For more complete information about the Certificates and Atlas, you should read this entire prospectus, as well as the other documents to which it refers to fully understand the terms of the Certificates. Unless otherwise indicated, "we," "us," "our" and similar terms, as well as references to the "Company" and "Atlas," refer to Atlas Air, Inc. and its subsidiaries. The term "you" refers to Certificateholders.

THE EXCHANGE OFFER

The Certificates...........  On January 28, 2000, we established three Atlas Air
                             2000-1 Pass Through Trusts (the "Trusts"). The
                             three Trusts are referred to as the "Class A
                             Trust," the "Class B Trust" and the "Class C
                             Trust." The Class A Trust issued "Class A
                             Certificates," the Class B Trust issued "Class B
                             Certificates" and the Class C Trust issued "Class C
                             Certificates," which represent fractional undivided
                             interests in the respective Trusts.

                             On January 28, 2000, we privately placed an
                             aggregate of $124,639,000 Class A Certificates,
                             $44,741,000 Class B Certificates and $47,937,000
                             Class C Certificates, pursuant to exemptions from
                             the SEC registration requirements. The "Initial
                             Purchasers" of the Certificates were Morgan Stanley
                             & Co. Incorporated, Deutsche Bank Securities Inc.
                             and Salomon Smith Barney Inc.

                             We have used all of the proceeds of the
                             Certificates to purchase Equipment Notes relating
                             to the acquisition of two new Boeing 747-400F
                             Aircraft.

                             When we use the term "Old Certificates" in this
                             prospectus, we mean the Class A, Class B and Class
                             C Certificates, Series 2000-1 privately placed with
                             the Initial Purchasers on January 28, 2000 and
                             which were not registered with the SEC. When we use
                             the term "New Certificates" in this prospectus, we
                             mean the Class A, Class B and Class C Certificates
                             registered with the SEC and offered hereby in
                             exchange for the Old Certificates.

                             When we use the term "Certificates" in this
                             prospectus, the related discussion applies to the
                             Old Certificates and the New Certificates.

Registration Agreement.....  On January 28, 2000, we entered into a Registration
                             Rights Agreement with the Initial Purchasers and
                             Trustee providing, among other things, for the
                             Exchange Offer.

The Exchange Offer.........  We are offering New Certificates in exchange for an
                             equal principal amount of Old Certificates. The New
                             Certificates will be issued to satisfy our
                             obligations under the Registration Rights
                             Agreement. The New Certificates will be entitled to
                             the benefits of and will be governed by the same
                             Pass Through Trust Agreements that govern the Old
                             Certificates. The form and terms of the New
                             Certificates are the same in all material respects
                             as the form and terms of the Old Certificates,
                             except that we registered the New Certificates
                             under the Securities Act so their transfer is not
                             restricted like the Old

                                        1

                             Certificates and the New Certificates are not
                             entitled to liquidated damages under the
                             Registration Rights Agreement.

                             As of the date of this prospectus, the aggregate
                             principal amount of Old Certificates outstanding is
                             $217,317,000.

Conditions to the Exchange
  Offer....................  The Exchange Offer is not conditioned upon any
                             minimum principal amount of Old Certificates being
                             tendered for exchange. However, the Exchange Offer
                             is subject to certain customary conditions, which

(1) These percentages are calculated as of January 2, 2001, the first Regular Distribution Date after all the Aircraft are scheduled to have been delivered. In making such calculations, we have assumed that all Aircraft are delivered prior to such date, the maximum amount of Equipment Notes is issued, the aggregate appraised base value for the Aircraft is $310,002,300 as of such date and that all principal payments through such date have been made on the Equipment Notes. The appraised base value is only an estimate and reflects certain assumptions, which may not reflect current market conditions. See "Description of the Aircraft and the Appraisals -- The Appraisals."

EQUIPMENT NOTES AND THE AIRCRAFT

Set forth below is certain information about the Equipment Notes expected to be held in the Trusts and the Aircraft expected to secure such Equipment Notes:

(1) The actual delivery month for each Aircraft was April 2000.

(2) The actual principal amount may be less depending on the circumstances of the financing of such Aircraft. The aggregate principal amount of all of the Equipment Notes will not exceed the aggregate face amount of the Certificates.

(3) The appraised base value of each Aircraft set forth above is the lesser of the average and median values of such Aircraft as appraised by three independent appraisal and consulting firms, projected as of the scheduled delivery month of each Aircraft. Such appraisals are based upon varying assumptions (which may not reflect current market conditions) and upon varying methodologies. An appraisal is only an estimate of value and should not be relied upon as a measure of realizable value. See "Risk Factors -- Risk Factors Relating to the New Certificates and the Exchange Offer -- Appraisals and Realizable Value of the Aircraft."

LOAN TO AIRCRAFT VALUE RATIOS

The following table sets forth loan to Aircraft value ratios ("LTVs") for each Class of Certificates as of January 2, 2001 (the first Regular Distribution Date that occurs after all Aircraft are scheduled to be delivered) and each January 2 Regular Distribution Date thereafter. The LTVs for any Class of Certificates as of dates prior to January 2, 2001, are not meaningful, since during such period all of the Equipment Notes expected to be acquired by the Trusts and the related Aircraft will not be included in the calculation. The table should not be considered a forecast or prediction of expected or likely LTVs but simply a mathematical calculation based on one set of assumptions. See "Risk Factors -- Risk Factors Relating to the New Certificates and the Exchange Offer -- Appraisals and Realizable Value of the Aircraft."

(1) We have assumed that the initial appraised value of each Aircraft, determined as described under "-- Equipment Notes and the Aircraft," declines by 3% per year for the first 20 years after the year of delivery of such Aircraft and by 4% per year thereafter. Different depreciation assumptions would result in material differences in the LTVs.

(2) In calculating the outstanding balances, we have assumed that the Trusts will acquire the maximum principal amount of Equipment Notes for all Aircraft.

(3) The LTVs for each Class of Certificates were obtained for each Regular Distribution Date by dividing (i) the expected outstanding balance of such Class together with the expected outstanding balance of all other Classes equal or senior in right of payment to such Class after giving effect to the distributions expected to be made on such date, by (ii) the assumed value of all of the Aircraft on such date based on the assumptions described above. The outstanding balances and LTVs may change if, among other things, the aggregate principal amount of the Equipment Notes acquired by the Trusts is less than the maximum permitted under the terms of the offering or the amortization of the Equipment Notes differs from the assumed amortization schedule calculated for purposes of this prospectus.

The above table was compiled on an aggregate basis. However, the Equipment Notes for an Aircraft will not have a security interest in any other Aircraft. This means that any excess proceeds realized from the sale of an Aircraft or other exercise of remedies will not be available to cover any shortfalls on the

6

Equipment Notes relating to any other Aircraft. See "Description of the Equipment Notes -- Loan to Value Ratios of Equipment Notes" for an example of LTVs for the Equipment Notes issued in respect of individual Aircraft, which may be more relevant in a default situation than the aggregate values shown above.

CASH FLOW STRUCTURE

Set forth below is a diagram illustrating the structure for the offering of the Old Certificates and certain cash flows:

[Atlas Air, Inc. Flow Chart]


(1) Each Aircraft leased to us will be subject to a separate Lease and a related Indenture. Each Aircraft owned by us will be subject to a separate Indenture. We will have the ability to enter into a sale/leaseback transaction with respect to any Aircraft that we initially own.

(2) The proceeds of the offering of each Class of Old Certificates initially are held in escrow and were deposited with the Depositary. The Depositary holds such funds as an interest-bearing Deposit. Each Trust will withdraw funds from the Deposit relating to such Trust to purchase Equipment Notes from time to time as each Aircraft is financed. The scheduled payments of interest on the Equipment Notes and on the Deposit relating to a Trust, taken together, will be sufficient to pay accrued interest on the outstanding Certificates of such Trust. The Liquidity Facilities will not cover interest on the Deposits. On April 5, 2000, $108,548,000 was withdrawn from escrow to purchase the first Boeing Aircraft and on April 25, 2000, $108,769,000 was withdrawn from escrow to purchase the second Boeing Aircraft.

                             will be the outstanding balance of the applicable
                             Class or Classes of Certificates plus accrued and
                             unpaid interest.

Liquidity Facilities.......  Under the Liquidity Facility for each Trust, the
                             Liquidity Provider will, if necessary, make
                             advances in an aggregate amount sufficient to pay
                             interest on the applicable Certificates on up to

                             Depositaries.

                             Notwithstanding the subordination provisions
                             applicable to the Certificates, the holders of the
                             Certificates issued by each Trust will be entitled
                             to receive and retain the proceeds of drawings
                             under the Liquidity Facility for such Trust.

                             Upon each drawing under any Liquidity Facility to
                             pay interest on the Certificates, the Subordination
                             Agent will reimburse the applicable Liquidity
                             Provider for the amount of such drawing. Such
                             reimbursement obligation and all interest, fees and
                             other amounts owing to the applicable Liquidity
                             Provider will rank senior to the Certificates in
                             right of payment.

Escrowed Funds.............  Funds paid to the Escrow Agent by the
                             Certificateholders were deposited with the
                             Depositary and were held as Deposits pursuant to
                             separate Deposit Agreements for each Trust. Funds
                             were withdrawn by the Trustees in April, 2000 to
                             purchase Equipment Notes to finance the acquisition
                             of the two Aircraft. On each Regular Distribution
                             Date, the Depositary will pay interest accrued on
                             the Deposit relating to such Trust at a rate per
                             annum equal to the interest rate applicable to the
                             Certificates issued by such Trust. The Deposits
                             relating to each Trust and interest paid thereon
                             will not be subject to the subordination provisions
                             applicable to the Certificates. The Deposits cannot
                             be used to pay any other amount in respect of the
                             Certificates.

                             Series C Equipment Notes issued with respect to
                             each Aircraft. We may enter into a leveraged lease
                             financing or a secured debt financing with respect
                             to any of the Aircraft. Each financing will be made
                             pursuant to forms of financing agreements attached
                             to the Note Purchase Agreement. We may elect to
                             convert an Owned

                                       10

                             Aircraft to a Leased Aircraft at any time by
                             entering into a sale/ leaseback transaction. In the
                             case of a Leased Aircraft, the terms of the
                             financing agreements entered into may differ from
                             the forms of such agreements described in this
                             prospectus because a third party -- the Owner
                             Participant -- will provide a portion of the
                             financing of the Aircraft and may request changes.
                             However, under the Note Purchase Agreement, the
                             terms of such financing agreements must (a) contain
                             the Mandatory Document Terms set forth in the Note
                             Purchase Agreement and (b) not vary the Mandatory

                             Agreement. In addition, we must (a) certify to the
                             Trustees that any such modifications do not
                             materially and adversely affect the
                             Certificateholders and (b) obtain written

                             Agencies") that the use of versions of such
                             agreements modified in any material respect will
                             not result in a withdrawal, suspension or
                             downgrading of the rating of any Class of
                             Certificates. The Trustees are not obligated to
                             purchase Equipment Notes if, at the time of
                             issuance, we are in bankruptcy or certain other
                             specified events have occurred. See "Description of
                             the Certificates -- Obligation to Purchase

                             such Equipment Notes. However, our scheduled rental
                             obligations under the related Lease will be in
                             amounts sufficient to pay scheduled payments on
                             such Equipment Notes.

                             OWNED AIRCRAFT. If we purchase an Aircraft, the
                             related Equipment Notes will be issued by us.

(b) Interest...............  The Equipment Notes held in each Trust will accrue
                             interest at the rate per annum for the Certificates
                             issued by such Trust set forth on the cover page of
                             this prospectus, subject to certain adjustments
                             described in "-- The Exchange Offer." Interest will
                             be payable on January 2 and July 2 of each year,
                             commencing on July 2, 2000. Interest is calculated
                             on the basis of a 360-day year consisting of twelve
                             30-day months.

(c) Principal..............  Principal payments on the Series A, Series B and
                             Series C Equipment Notes are scheduled to be
                             payable on January 2 and July 2 in certain years,
                             commencing on January 2, 2001.

(d) Redemption and
    Purchase...............  AIRCRAFT EVENT OF LOSS. If an Event of Loss occurs
                             with respect to an Aircraft, all of the Equipment
                             Notes issued with respect to such

                                       11

                             Aircraft will be redeemed, unless such Aircraft is
                             replaced by us under the related financing
                             agreements. The redemption price in such case will
                             be the unpaid principal amount of such Equipment
                             Notes, together with accrued interest, but without
                             any premium.

                             OPTIONAL REDEMPTION. The issuer of the Equipment
                             Notes with respect to an Aircraft may elect to
                             redeem them prior to maturity. The redemption price
                             in such case will be the unpaid principal amount of
                             such Equipment Notes, together with accrued
                             interest plus a Make-Whole Premium. See
                             "Description of the Equipment Notes -- Redemption."

                             PURCHASE BY OWNER. In the case of a Leased
                             Aircraft, if a Lease Event of Default is
                             continuing, the applicable Owner Trustee or Owner
                             Participant may elect to purchase all of the
                             Equipment Notes with respect to such Aircraft,
                             subject to the terms of the applicable Leased
                             Aircraft Indenture. The purchase price in such case
                             will be the unpaid principal amount of such
                             Equipment Notes, together with accrued interest,
                             but without any premium (provided that a Make-Whole
                             Premium will be payable under certain circumstances
                             specified in the Leased Aircraft Indenture). In the
                             case of an Owned Aircraft, we will have no
                             comparable right to purchase the Equipment Notes
                             under such circumstances.

(e) Security...............  The Equipment Notes issued with respect to each
                             Aircraft will be secured by a security interest in
                             such Aircraft and, in the case of each Leased
                             Aircraft, in the related Owner Trustee's rights
                             under the Lease with respect to such Aircraft (with
                             certain exceptions).

                             The Equipment Notes will not be
                             cross-collateralized (except in certain cases, if
                             any, where the related Owner Participant and Atlas
                             shall agree otherwise). This means that the
                             Equipment Notes issued in respect of an Aircraft
                             will not be secured by any other Aircraft or Leases
                             and that any excess proceeds from the sale of an
                             Aircraft or other exercise of remedies with respect
                             to such Aircraft will not be available to cover any
                             shortfall with respect to any other Aircraft.

                             By virtue of the Intercreditor Agreement, the
                             Equipment Notes are cross-subordinated. This means
                             that payments received on a junior class of
                             Equipment Notes issued in respect of one Aircraft
                             may be applied in accordance with the priority of
                             payment provisions set forth in the Intercreditor
                             Agreement to make payments in respect of a more
                             senior Class of Certificates.

                             There are no cross-default provisions in the
                             Indentures or in the Leases. This means that if the
                             Equipment Notes issued with respect to one or more
                             Aircraft are in default and the Equipment Notes
                             issued with respect to the remaining Aircraft are
                             not in default, no remedies will be exercisable
                             with respect to the remaining Aircraft.

Section 1110 Protection....  As a condition of the acquisition of Aircraft with
                             the proceeds of Equipment Notes, our outside
                             counsel will provide its opinion to the Trustees
                             that the benefits of Section 1110 of the U.S.
                             Bankruptcy Code are available with respect to the
                             remedies of the Loan Trustees against such
                             Aircraft.

                                       12

Certain Federal Income Tax
  Consequences.............  The exchange of the Old Certificates for the New
                             Certificates will not be a taxable event for U.S.
                             federal income tax purposes. See "Certain United
                             States Federal Income Tax Consequences."

Certain ERISA
Considerations.............  Each person who acquires a New Certificate will be
                             deemed to have represented that either (a) no
                             employee benefit plan assets have been used to
                             purchase such New Certificate or (b) the purchase
                             and holding of such New Certificate are exempt from
                             the prohibited transaction restrictions of the
                             Employee Retirement Income Security Act of 1974 and
                             the Internal Revenue Code of 1986 pursuant to one
                             or more prohibited transaction statutory or
                             administrative exemptions. See "ERISA
                             Considerations."

Ratings of the
Certificates...............  The Class A, Class B and Class C Certificates are
                             rated by Moody's, Standard & Poor's and Duff &
                             Phelps Credit Rating Co. ("Duff & Phelps"), as set

forth below:

A rating is not a recommendation to purchase, hold or sell Certificates, since such rating does not address market price or suitability for a particular investor. There can be no assurance that such ratings will not be lowered or withdrawn by a rating agency. See "Risk Factors -- Risk Factors Relating to the New Certificates and the Exchange Offer -- Ratings of the Certificates" and "Description of the Equipment Notes -- Remedies."

SUMMARY CONSOLIDATED FINANCIAL AND OPERATING DATA

A discussion of the consolidated financial and operating data relating to Atlas is included in our Form 10-K for the year ended December 31, 1999 which is incorporated herein by reference.

RATIO OF EARNINGS TO FIXED CHARGES

                                                                YEAR ENDED DECEMBER 31,
                                                         -------------------------------------
                                                         1995    1996    1997    1998    1999

Ratio of earnings to fixed charges(1)..................  1.86x   2.11x   1.30x   1.34x   1.57x


(1) In calculating the ratio of earnings to fixed charges, earnings consists of income (loss) prior to income tax benefit (expense), as adjusted to exclude the "Write-off of capital investment and other" in the second quarter of 1997, and fixed charges (excluding capitalized interest for the period). Fixed charges consist of interest expense (including amounts capitalized), amortization of debt issuance costs and one-third of rental payments on operating leases (such one-third portion having been deemed by us to represent the interest portion of such payments).

RISK FACTORS

You should carefully read the following risk factors before tendering your Old Certificates in the Exchange Offer. The risk factors set forth below (other than "Consequences of Failure to Exchange") are generally applicable to Old Certificates as well as New Certificates.

RISK FACTORS RELATING TO ATLAS

A discussion of risk factors relating to Atlas is included in our Form 10-K for the year ended December 31, 1999 which is incorporated herein by reference.

RISK FACTORS RELATING TO THE NEW CERTIFICATES AND THE EXCHANGE OFFER

CONSEQUENCES OF FAILURE TO EXCHANGE -- Holders of Old Certificates who chose not to participate in the Exchange Offer will be subject to continued restrictions on the transfer of such Certificates.

Holders of Old Certificates who do not exchange their Old Certificates for New Certificates pursuant to the Exchange Offer will continue to be subject to the restrictions on transfer of such Old Certificates as set forth in the legend thereon. In general, the Old Certificates may not be offered or sold, unless registered under the Securities Act, except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We do not currently anticipate that we will register the Old Certificates under the Securities Act. To the extent that Old Certificates are tendered and accepted in the Exchange Offer, the trading market for untendered and tendered but unaccepted Old Certificates could be adversely affected.

APPRAISALS AND REALIZABLE VALUE OF THE AIRCRAFT -- If the realized value of an Aircraft is not equal to its appraised value, the remedies provided to Certificateholders under an Indenture would be insufficient to cover the payments on the Certificates.

Three independent appraisal and consulting firms prepared appraisals of the Aircraft in connection with the sale of the Old Certificates in January, 2000. Letters summarizing such appraisals are annexed to this prospectus as Appendix B. Such appraisals, which are based on the base value of the Aircraft, rely on certain varying assumptions and methodologies and may not reflect current market conditions that could affect the fair market value of the Aircraft or the actual purchase price to be paid by us. Appraisals that are based on different assumptions and methodologies may result in valuations that are materially different from those contained in the appraisals. See "Description of the Aircraft and the Appraisals -- The Appraisals."

An appraisal is only an estimate of value. The proceeds realized upon a sale of any Aircraft may be less than the appraised value. The value of an Aircraft if the remedies are exercised under the applicable Indenture will depend on market and economic conditions, the supply of similar aircraft, the availability of buyers, the condition of the Aircraft and other factors. Accordingly, there can be no assurance that the proceeds realized upon any such exercise of remedies would be sufficient to satisfy in full payments due on the Certificates.

REPOSSESSION -- The Loan Trustee may encounter difficulty repossessing an Aircraft due to circumstances beyond its control. As a result, the benefits of the security interest created in the Equipment Notes could be limited.

There are no general geographic restrictions on our ability to operate the Aircraft. Although we do not currently intend to do so, we are permitted to register the Aircraft in foreign jurisdictions, subject to certain conditions. In addition, we are permitted to lease any Owned Aircraft and sublease any Leased Aircraft, subject to certain conditions. It may be difficult, time-consuming and expensive for the Loan Trustee to exercise its repossession rights if the Aircraft is located outside the United States, is registered in a foreign location or is subleased to a foreign operator. Additional difficulties may exist when a permitted sublessee, in the case of a Leased Aircraft, or lessee, in the case of an Owned Aircraft is the

15

subject of a bankruptcy, insolvency or similar event. In addition, certain jurisdictions may allow for certain other liens or other third party rights to have priority over the security interest in the Aircraft.

PRIORITY OF DISTRIBUTIONS; SUBORDINATION -- If there is a payment default under any Equipment Note or a Triggering Event occurs, the holders of one or more junior Classes of Certificates may not receive the full amount of interest due them.

Certain Classes of Certificates are subordinated to other Classes in rights to distributions. See "Description of the Certificates -- Subordination." Consequently, a payment default under any Equipment Note or a Triggering Event may cause the distribution to more senior Classes of Certificates of payments received from payment on one or more junior series of Equipment Notes. If this should occur, the interest accruing on the remaining Equipment Notes would be less than the interest accruing on the remaining Certificates. This is because the remaining Certificates of the junior Classes accrue interest at a higher rate than the remaining Equipment Notes, which include series applicable to the senior Classes bearing interest at a lower rate. As a result of this possible interest shortfall, the holders of one or more junior Classes of Certificates may not receive the full amount due to them after a payment default under any Equipment Note even if all Equipment Notes are eventually paid in full.

CONTROL OVER COLLATERAL; SALE OF COLLATERAL -- The ability of a Controlling Party to direct the Loan Trustee in an Indenture Event of Default may result in Certificateholders receiving a smaller amount of principal than anticipated.

If an Indenture Event of Default is continuing, subject to certain conditions, the Loan Trustee under such Indenture will be directed by the "Controlling Party" in exercising remedies under the Indenture including accelerating the applicable Equipment Notes, or foreclosing the lien on the Aircraft securing such Equipment Notes. See "Description of the Certificates -- Indenture Defaults and Certain Rights Upon an Indenture Default."

The Controlling Party will be:

- the Trustee of the Class A Trust (the "Class A Trustee");

- upon payment of final distributions to the holders of Class A Certificates, the Trustee of the Class B Trust ("Class B Trustee");

- upon payment of final distributions to the holders of Class B Certificates, the Trustee of the Class C Certificates ("Class C Trustee"); and

- under certain circumstances, the Liquidity Provider with the greatest amount of obligations owed to it.

During the continuation of any Indenture Event of Default, the Controlling Party may accelerate and sell the Equipment Notes issued under such Indenture, subject to certain limitations. See "Description of the Intercreditor Agreement -- Intercreditor Rights -- Sale of Equipment Notes or Aircraft." The market for Equipment Notes during any Indenture Event of Default may be very limited, and there can be no assurance as to the price at which they could be sold. If the Controlling Party sells any Equipment Notes for less than their outstanding principal amount, certain Certificateholders will receive a smaller amount of principal distributions than anticipated and will not have any claim for the shortfall against us, any Owner Trustee, any Owner Participant or any Trustee.

OWNER PARTICIPANT; REVISIONS TO AGREEMENTS -- Agreements described in the prospectus may differ from the descriptions of such agreements contained in the prospectus.

Atlas may seek commitments of one or more companies to act as the Owner Participant with respect to leveraged leases for one or more of the Aircraft. Such Owner Participants may request revisions to the forms of the Participation Agreement, the Lease and the Leased Aircraft Indenture attached to the Note Purchase Agreement. As a result, the actual Participation Agreement, Lease and Leased Aircraft

16

Indenture may differ from the description of such agreements contained in this prospectus. The degree to which such agreements may change is limited because:

- such agreements are required to contain the Mandatory Document Terms and the Mandatory Economic Terms;

- we are obligated to certify that any changes to the form agreements do not materially and adversely affect the Certificateholders; and

- we are obligated to obtain written confirmation from each Rating Agency that the use of versions of such agreements modified in any material respect will not result in a withdrawal, suspension or downgrading of the rating of any Class of Certificates.

RATINGS OF THE CERTIFICATES -- Ratings on the Certificates may not remain and the lowering or withdrawal of a rating by a Rating Agency may negatively impact the value of the Certificates.

It was a condition to the issuance of the Old Certificates that

- the Class A Certificates be rated not lower than A2 by Moody's, AA- by Duff & Phelps and AA- by Standard & Poor's;

- the Class B Certificates be rated not lower than Baa2 by Moody's, A- by Duff & Phelps and A- by Standard & Poor's; and

- the Class C Certificates be rated not lower than Ba2 by Moody's, BBB- by Duff & Phelps and BBB- by Standard & Poor's.

A rating is not a recommendation to purchase, hold or sell Certificates, since such rating does not address market price or suitability for a particular investor. A rating may not remain for any given period of time and may be lowered or withdrawn entirely by a rating agency if in its judgment circumstances in the future (including the downgrading of Atlas, the Depositary or the applicable Liquidity Provider) so warrant. See "Description of the Equipment Notes -- Remedies."

The rating of the Certificates is based primarily on the default risk of the Equipment Notes and the Depositary, the availability of the Liquidity Facility for the benefit of holders of the Certificates, the collateral value provided by the Aircraft relating to the Equipment Notes and the subordination provisions applicable to the Certificates. Standard & Poor's has indicated that its rating applies to a unit consisting of Certificates representing the Trust Property and Escrow Receipts initially representing undivided interests in certain rights to $217,317,000 of the Deposits. Amounts deposited under the Escrow Agreements are not the property of Atlas and are not entitled to the benefits of Section 1110 of the U.S. Bankruptcy Code. Neither the Certificates nor the Escrow Receipts may be separately assigned or transferred.

ABSENCE OF AN ESTABLISHED MARKET FOR THE CERTIFICATES -- If an active public market does not develop or continue, you may have trouble reselling Certificates.

Prior to the Exchange Offer, there was no public market for the Certificates and neither Atlas nor any Trust intends to apply for listing of the Certificates on any securities exchange or otherwise. The Initial Purchasers may assist in resales of the Certificates, but they are not required to do so. An active public market for the Certificates may not develop. If an active public market does develop, it might not continue or it might not be sufficiently liquid to allow the resale of any particular Certificates.

PROCEDURES FOR TENDER OF OLD CERTIFICATES -- If you fail to deliver the proper documentation to the Exchange Agent in a timely fashion, your tender of Old Certificates will be rejected.

The New Certificates will be issued in exchange for the Old Certificates only after timely receipt by the Exchange Agent of the Old Certificates, a properly completed and executed Letter of Transmittal and all other required documentation. Holders of Old Certificates who wish to tender their Old Certificates in exchange for New Certificates should allow sufficient time to ensure timely delivery. None of the

17

Exchange Agent, the Trustee or the Company is under any duty to give holders of Old Certificates notification of defects or irregularities with respect to tenders of Old Certificates for exchange. Old Certificates that are not tendered or are tendered but not accepted will, following the Exchange Offer, continue to be subject to the existing transfer restrictions. In addition, holders of Old Certificates who tender Old Certificates in the Exchange Offer to participate in a distribution of the New Certificates will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

THE EXCHANGE OFFER

This summary describes certain provisions of the registration rights agreement dated as of January 28, 2000 (the "Registration Rights Agreement") among Atlas, the Initial Purchasers and the Trustee but is not complete. We encourage you to review the Registration Rights Agreement, which has been filed as an exhibit to the Registration Statement and a copy of which is available as set forth under the heading "Where You Can Find More Information."

TERMS OF THE EXCHANGE OFFER

General

In connection with the issuance of the Old Certificates pursuant to a placement agreement dated as of January 20, 2000, between Atlas and the Initial Purchasers (the "Placement Agreement"), the Initial Purchasers and their respective assignees became entitled to the benefits of the Registration Rights Agreement.

Under the Registration Rights Agreement, we are obligated to use our best efforts:

- to file the Registration Statement, of which this prospectus is a part, with the SEC for a registered exchange offer (the "Exchange Offer") with respect to an issue of New Certificates identical in all material respects to the Old Certificates (except that the New Certificates would not contain terms with respect to transfer restrictions or interest rate increases) within 120 calendar days after January 28, 2000, the date the Old Certificates were issued (the "Issuance Date");

- to cause the Registration Statement to become effective within 60 days after filing of the Registration Statement with the SEC;

- to have the Registration Statement remain effective until the closing of the Exchange Offer; and

- to have the Exchange Offer consummated not later than 60 days after the effective date of the Registration Statement.

We will keep the Exchange Offer open for a period of not less than 30 calendar days after the date notice of the Exchange Offer is mailed to the holders of the Certificates. If the Exchange Offer is commenced and consummated within the time periods described in this paragraph, we will satisfy these requirements of the Registration Rights Agreement.

Upon the terms and subject to the conditions set forth in this prospectus and in the Letter of Transmittal (which together constitute the Exchange Offer), all Old Certificates validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the Expiration Date will be accepted for exchange. New Certificates of the same class will be issued in exchange for an equal principal amount of outstanding Old Certificates accepted in the Exchange Offer. Old Certificates may be tendered only in integral multiples of $1,000. This prospectus, together with the Letter of Transmittal, is being sent to all registered holders as of , 2000. The Exchange Offer is not conditioned upon any minimum principal amount of Old Certificates being tendered for exchange. However, the obligation to accept Old Certificates for exchange pursuant to the Exchange Offer is subject to certain conditions as set forth herein under "-- Conditions."

Old Certificates shall be deemed to have been accepted as validly tendered when, as and if the Trustee has given oral or written notice thereof to the Exchange Agent (as defined herein). The Exchange Agent will act as agent for the tendering holders of Old Certificates for the purposes of receiving the New Certificates and delivering New Certificates to such holders.

Based on interpretations by the staff of the SEC, as set forth in no-action letters issued to third parties, we believe that the New Certificates issued pursuant to the Exchange Offer may be offered for resale, resold or otherwise transferred by holders thereof (other than a broker-dealer who acquires such New Certificates directly from the Trustee for resale pursuant to Rule 144A under the Securities Act or

19

any other available exemption under the Securities Act or any holder that is an "affiliate" of the Company as defined under Rule 405 of the Securities Act), without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such New Certificates are acquired in the ordinary course of such holders' business and such holders are not engaged in, and do not intend to engage in, a distribution of such New Certificates and have no arrangement with any person to participate in a distribution of such New Certificates. By tendering the Old Certificates in exchange for New Certificates, each holder, other than a broker-dealer, will represent to the Company that:

- it is not an affiliate of the Company (as defined under Rule 405 of the Securities Act) nor a broker-dealer tendering Old Certificates acquired directly from the Company for its own account;

- any New Certificates to be received by it will be acquired in the ordinary course of its business; and

- it is not engaged in, and does not intend to engage in, a distribution of such New Certificates and has no arrangement or understanding to participate in a distribution of the New Certificates.

If a holder of Old Certificates is engaged in or intends to engage in a distribution of the New Certificates or has any arrangement or understanding with respect to the distribution of the New Certificates to be acquired pursuant to the Exchange Offer, such holder may not rely on the applicable interpretations of the staff of the SEC and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any secondary resale transaction. Each Participating Broker-Dealer that receives New Certificates for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Certificates. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a Participating Broker-Dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a Participating Broker-Dealer in connection with resales of New Certificates received in exchange for Old Certificates where such Old Certificates were acquired by such Participating Broker-Dealer as a result of market-making activities or other trading activities.

In the event that any changes in law or the applicable interpretations of the staff of the SEC do not permit Atlas to effect the Exchange Offer, if the Registration Statement is not declared effective within 60 calendar days after the filing thereof with the SEC under certain circumstances or the Exchange Offer is not consummated within 30 days after the effectiveness of the Registration Statement under certain other circumstances, at the request of a holder not eligible to participate in the Exchange Offer or under certain other circumstances described in the Registration Rights Agreement, Atlas will, in lieu of effecting the registration of the New Certificates pursuant to the Registration Statement and at no cost to the holders of Old Certificates:

- as promptly as practicable, file with the SEC a shelf registration statement (the "Shelf Registration Statement") covering resales of the Old Certificates;

- use its best efforts to cause the Shelf Registration Statement to be declared effective under the Securities Act by the 180th calendar day after the Issuance Date; and

- use its best efforts to keep effective the Shelf Registration Statement for a period of two years after its effective date (or for such shorter period as shall end when all of the Old Certificates covered by the Shelf Registration Statement have been sold pursuant thereto or may be freely sold pursuant to Rule 144 under the Securities Act).

In the event that neither the consummation of the Exchange Offer nor the declaration by the SEC of the Shelf Registration Statement to be effective (each, a "Registration Event") occurs on or prior to the 210th calendar day following the Issuance Date, the interest rate per annum borne by the Equipment Notes and passed through to holders of Old Certificates shall be increased by 0.50% effective from and including August 25, 2000, to but excluding the date on which a Registration Event occurs. In the event that the Shelf Registration Statement ceases to be effective at any time, during the period we are required

20

to keep such Shelf Registration Statement effective, for more than 60 days, whether or not consecutive, during any 12-month period, the interest rate per annum borne by the Equipment Notes shall be increased by 0.50% from the 61st day of the applicable 12-month period such Shelf Registration Statement ceases to be effective until such time as the Shelf Registration Statement again becomes effective.

Upon consummation of the Exchange Offer, subject to certain exceptions, holders of Old Certificates who do not exchange their Old Certificates for New Certificates in the Exchange Offer will no longer be entitled to registration rights and will not be able to offer or sell their Old Certificates, unless such Old Certificates are subsequently registered under the Securities Act which, subject to limited exceptions, we will have no obligation to do, except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. See "Risk Factors -- Risk Factors Relating to the New Certificates and the Exchange Offer -- Consequences of Failure to Exchange."

Expiration Date; Extensions; Amendments; Termination

The term "Expiration Date" shall mean , 2000 (30 calendar days following the commencement of the Exchange Offer), unless we, in our sole discretion, extend the Exchange Offer, in which case the term "Expiration Date" shall mean the latest date to which the Exchange Offer is extended. Notwithstanding any extension of the Exchange Offer, if the Exchange Offer is not consummated by August 25, 2000, the interest rate borne by the Equipment Notes and passed through to the Certificateholders is subject to increase. See "-- General."

In order to extend the Expiration Date, we will notify the Exchange Agent of any extension by oral or written notice and will mail to the record holders of Old Certificates an announcement thereof, each prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date. Such announcement may state that we are extending the Exchange Offer for a specified period of time.

We reserve the right:

- to delay acceptance of any Old Certificates, to extend the Exchange Offer or to terminate the Exchange Offer and not permit acceptance of Old Certificates not previously accepted if any of the conditions set forth herein under "-- Conditions" shall have occurred and shall not have been waived by us, by giving oral or written notice of such delay, extension or termination to the Exchange Agent; or

- to amend the terms of the Exchange Offer in any manner deemed by us to be advantageous to the holders of the Old Certificates.

Any such delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by oral or written notice thereof to the Exchange Agent. If the Exchange Offer is amended in a manner determined by us to constitute a material change, we will promptly disclose such amendment in a manner reasonably calculated to inform the holders of the Old Certificates of such amendment.

Without limiting the manner in which we may choose to make a public announcement of any delay, extension, amendment or termination of the Exchange Offer, we shall have no obligation to publish, advertise, or otherwise communicate any such public announcement, other than by making a timely release to an appropriate news agency.

INTEREST ON THE NEW CERTIFICATES

The New Certificates will accrue interest at the applicable per annum rate for such Trust set forth on the cover page of this prospectus, from the last date on which interest was paid on the Old Certificates surrendered in exchange therefor. Interest on the New Certificates is payable on January 2 and July 2 of each year commencing upon the consummation of the Exchange Offer, subject to the terms of the Intercreditor Agreement.

PROCEDURES FOR TENDERING

To tender in the Exchange Offer, a holder must complete, sign and date the Letter of Transmittal, or a facsimile thereof, have the signatures thereon guaranteed if required by the Letter of Transmittal and mail or otherwise deliver such Letter of Transmittal or such facsimile, together with any other required documents, to the Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration Date. In addition, either:

- certificates for such Old Certificates must be received by the Exchange Agent along with the Letter of Transmittal;

- a timely confirmation of a book-entry transfer (a "Book-Entry Confirmation") of such Old Certificates, if such procedure is available, into the Exchange Agent's account at DTC (the "Book-Entry Transfer Facility") pursuant to the procedure for book-entry transfer described below, must be received by the Exchange Agent prior to the Expiration Date; or

- the holder must comply with the guaranteed delivery procedures described below.

The method of delivery of Old Certificates, Letters of Transmittal and all other required documents is at the election and risk of the holders. If such delivery is by mail, it is recommended that registered mail, properly insured, with return receipt requested, be used. In all cases, sufficient time should be allowed to assure timely delivery. No Letters of Transmittal or Old Certificates should be sent to Atlas. Delivery of all documents must be made to the Exchange Agent at its address set forth below. Holders may also request their respective brokers, dealers, commercial banks, trust companies or nominees to effect such tender for such holders.

The tender by a holder of Old Certificates will constitute an agreement between such holder and the Company in accordance with the terms and subject to the conditions set forth in this prospectus and in the Letter of Transmittal.

Only a holder of Old Certificates may tender such Old Certificates in the Exchange Offer. The term "holder" with respect to the Exchange Offer means any person in whose name Old Certificates are registered on our books or any other person who has obtained a properly completed bond power from the registered holder.

Any beneficial owner whose Old Certificates are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and who wishes to tender should contact such registered holder promptly and instruct such registered holder to tender on his behalf. If such beneficial owner wishes to tender on his own behalf, such beneficial owner must, prior to completing and executing the Letter of Transmittal and delivering his Old Certificates, either make appropriate arrangements to register ownership of the Old Certificates in such owner's name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time.

Signatures on a Letter of Transmittal or a notice of withdrawal, as the case may be, must be guaranteed by any member firm of a registered national securities exchange or of the National Association of Securities Dealers, Inc., a commercial bank or trust company having an office or correspondent in the United States or an "eligible guarantor" institution within the meaning of Rule 17Ad-15 under the Exchange Act (each, an "Eligible Institution") unless the Old Certificates tendered pursuant thereto are tendered (a) by a registered holder who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on the Letter of Transmittal or (b) for the account of an Eligible Institution.

If the Letter of Transmittal is signed by a person other than the registered holder of any Old Certificates listed therein, such Old Certificates must be endorsed or accompanied by bond powers and a proxy which authorizes such person to tender the Old Certificates on behalf of the registered holder, in each case as the name of the registered holder or holders appears on the Old Certificates.

22

If the Letter of Transmittal or any Old Certificates or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and unless waived, evidence satisfactory to us of their authority to so act must be submitted with the Letter of Transmittal.

All questions as to the validity, form, eligibility (including time of receipt) and withdrawal of the tendered Old Certificates will be determined by us in our sole discretion, which determination will be final and binding. We reserve the absolute right to reject any and all Old Certificates not properly tendered or any Old Certificates which, if accepted, would, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any irregularities or conditions of tender as to particular Old Certificates. Our interpretation of the terms and conditions of the Exchange Offer, including the instructions in the Letter of Transmittal, will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Old Certificates must be cured within such time as we shall determine. Neither we, the Exchange Agent nor any other person shall be under any duty to give notification of defects or irregularities with respect to tenders of Old Certificates, nor shall any of us incur any liability for failure to give such notification. Tenders of Old Certificates will not be deemed to have been made until such irregularities have been cured or waived. Any Old Certificates received by the Exchange Agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned without cost to such holder by the Exchange Agent to the tendering holders of Old Certificates, unless otherwise provided in the Letter of Transmittal, as soon as practicable following the Expiration Date.

In addition, we reserve the right in our sole discretion, subject to the provisions of the Indenture, to (a) purchase or make offers for any Old Certificates that remain outstanding subsequent to the Expiration Date or, as set forth under "-- Conditions," to terminate the Exchange Offer in accordance with the terms of the Registration Rights Agreement and (b) to the extent permitted by applicable law, purchase Old Certificates in the open market, in privately negotiated transactions or otherwise. The terms of any such purchases or offers could differ from the terms of the Exchange Offer.

ACCEPTANCE OF OLD CERTIFICATES FOR EXCHANGE; DELIVERY OF NEW CERTIFICATES

Upon satisfaction or waiver of all of the conditions to the Exchange Offer, all Old Certificates properly tendered will be accepted, promptly after the Expiration Date, and the New Certificates will be issued promptly after acceptance of the Old Certificates. See "-- Conditions" below. For purposes of the Exchange Offer, Old Certificates shall be deemed to have been accepted validly tendered for exchange when, as and if we have given oral or written notice thereof to the Exchange Agent.

In all cases, issuance of New Certificates for Old Certificates that are accepted for exchange pursuant to the Exchange Offer will be made only after timely receipt by the Exchange Agent of certificates for such Old Certificates or a timely Book-Entry Confirmation of such Old Certificates into the Exchange Agent's account at the Book-Entry Transfer Facility, a properly completed and duly executed Letter of Transmittal and all other required documents. If any tendered Old Certificates are not accepted for any reason set forth in the terms and conditions of the Exchange Offer or if Old Certificates are submitted for a greater principal amount than the holder desires to exchange, such unaccepted or nonexchanged Old Certificates will be returned without expense to the tendering holder thereof (or, in the case of Old Certificates tendered by book-entry transfer procedures described below, such nonexchanged Old Certificates will be credited to an account maintained with such Book-Entry Transfer Facility) as promptly as practicable after the expiration or termination of the Exchange Offer.

BOOK-ENTRY TRANSFER

The Exchange Agent will make a request to establish an account with respect to the Old Certificates at the Book-Entry Transfer Facility for purposes of the Exchange Offer within two business days after the date of this prospectus. Any financial institution that is a participant in the Book-Entry Transfer Facility's systems may make book-entry delivery of Old Certificates by causing the Book-Entry Transfer Facility to

23

transfer such Old Certificates into the Exchange Agent's account at the Book-Entry Transfer Facility in accordance with such Book-Entry Transfer Facility's procedures for transfer. However, although delivery of Old Certificates may be effected through book-entry transfer at the Book-Entry Transfer Facility, the Letter of Transmittal or facsimile thereof with any required signature guarantees and any other required documents must, in any case, be transmitted to and received by the Exchange Agent at one of the addresses set forth below under "-- Exchange Agent" on or prior to the Expiration Date or the guaranteed delivery procedures described below must be complied with.

GUARANTEED DELIVERY PROCEDURES

If a registered holder of the Old Certificates desires to tender such Old Certificates, and the Old Certificates are not immediately available, or time will not permit such holder's Old Certificates or other required documents to reach the Exchange Agent before the Expiration Date, or the procedures for book- entry transfer cannot be completed on a timely basis, a tender may be effected pursuant to the following:

- the tender is made through an Eligible Institution;

- prior to the Expiration Date, the Exchange Agent receives from such Eligible Institution a properly completed and duly executed Letter of Transmittal (or a facsimile thereof) and Notice of Guaranteed Delivery, substantially in the form provided by the Company (by facsimile transmission, mail or hand delivery), setting forth the name and address of the holder of Old Certificates and the amount of Old Certificates tendered, stating that the tender is being made thereby and guaranteeing that within three New York Stock Exchange ("NYSE") trading days after the date of execution of the Notice of Guaranteed Delivery, the certificates for all physically tendered Old Certificates, in proper form for transfer, or a Book-Entry Confirmation, as the case may be, and any other documents required by the Letter of Transmittal will be deposited by the Eligible Institution with the Exchange Agent; and

- the certificates for all physically tendered Old Certificates, in proper form for transfer, or a Book-Entry Confirmation, as the case may be, and all other documents required by the Letter of Transmittal are received by the Exchange Agent within three NYSE trading days after the date of execution of the Notice of Guaranteed Delivery.

WITHDRAWAL OF TENDERS

Tenders of Old Certificates may be withdrawn at any time prior to 5:00
p.m., New York City time, on the Expiration Date.

For a withdrawal to be effective, a written notice of withdrawal must be received by the Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration Date at one of the addresses set forth below under "-- Exchange Agent." Any such notice of withdrawal must specify the name of the person having tendered the Old Certificates to be withdrawn, identify the Old Certificates to be withdrawn, including the principal amount of such Old Certificates, and (where certificates for Old Certificates have been transmitted) specify the name in which such Old Certificates are registered, if different from that of the withdrawing holder. If certificates for Old Certificates have been delivered or otherwise identified to the Exchange Agent, then, prior to the release of such certificates, the withdrawing holder must also submit the serial numbers of the particular certificates to be withdrawn and a signed notice of withdrawal with signatures guaranteed by an Eligible Institution unless such holder is an Eligible Institution. If Old Certificates have been tendered pursuant to the procedure for book-entry transfer described above, any notice of withdrawal must specify the name and number of the account at the Book-Entry Transfer Facility to be credited with the withdrawn Old Certificates and otherwise comply with the procedures of such facility. We will determine all questions as to the validity, form and eligibility (including time of receipt) of such notices. Our determination shall be final and binding on all parties. Any Old Certificates so withdrawn will be deemed not to have been validly tendered for exchange for purposes of the Exchange Offer. Any Old Certificates which have been tendered for exchange but which are not exchanged for any reason will be returned to the holder thereof without cost to such holder (or, in the case of Old

24

Certificates tendered by book-entry transfer into the Exchange Agent's account at the Book-Entry Transfer Facility pursuant to the book-entry transfer procedures described above, such Old Certificates will be credited to an account maintained with such Book-Entry Transfer Facility for the Old Certificates) as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offer. Properly withdrawn Old Certificates may be retendered by following one of the procedures described under "-- Procedures for Tendering" and "-- Book-Entry Transfer" above at any time on or prior to the Expiration Date.

CONDITIONS

Notwithstanding any other term of the Exchange Offer, Old Certificates will not be required to be accepted for exchange, nor will New Certificates be issued in exchange for any Old Certificates and we may terminate or amend the Exchange Offer before the acceptance of such Old Certificates, if because of any change in law, or applicable interpretations thereof by the SEC, we determine that we are not permitted to effect the Exchange Offer. In addition, we have no obligation to, and will not knowingly, permit acceptance of tenders of Old Certificates from our affiliates (within the meaning of Rule 405 under the Securities Act) or from any other holder or holders who are not eligible to participate in the Exchange Offer under applicable law or interpretations thereof by the SEC, or if the New Certificates to be received by such holder or holders of Old Certificates in the Exchange Offer, upon receipt, will not be tradable by such holder without restriction under the Securities Act and the Exchange Act and without material restrictions under the "blue sky" or securities laws of substantially all of the states of the United States.

FEES AND EXPENSES

We will pay the expenses of soliciting tenders pursuant to the Exchange Offer. The principal solicitation for tenders pursuant to the Exchange Offer is being made by mail; however, additional solicitations may be made by telegraph, telephone, telecopy or in person by our officers and regular employees.

We will not make any payments to brokers, dealers or other persons soliciting acceptances of the Exchange Offer. We will, however, pay the Exchange Agent reasonable and customary fees for its services and will reimburse the Exchange Agent for its reasonable out-of-pocket expenses in connection with its services. We may also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of the prospectus and related documents to the beneficial owners of the Old Certificates, and in handling or forwarding tenders for exchange.

25

We will pay the expenses to be incurred in connection with the Exchange Offer, including fees and expenses of the Exchange Agent and Trustee and accounting, legal, printing and related fees and expenses.

We will pay all transfer taxes, if any, applicable to the exchange of Old Certificates pursuant to the Exchange Offer. If, however, certificates representing New Certificates or Old Certificates for principal amounts not tendered or accepted for exchange are to be delivered to, or are to be registered or issued in the name of, any person other than the registered holder of the Old Certificates tendered, or if tendered Old Certificates are registered in the name of any person other than the person signing the Letter of Transmittal, or if a transfer tax is imposed for any reason other than the exchange of Old Certificates pursuant to the Exchange Offer, then the amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted with the Letter of Transmittal, the amount of such transfer taxes will be billed directly to such tendering holder.

USE OF PROCEEDS

There will be no cash proceeds payable to Atlas as a result of the issuance of New Certificates pursuant to the Exchange Offer. All of the proceeds from the sale of the Old Certificates were used to purchase Equipment Notes to finance all or a portion of Atlas' purchase price of the Owned Aircraft, including reimbursement of amounts paid by Atlas. Prior to utilization of such proceeds to purchase Equipment Notes, such proceeds from the sale of the Old Certificates of each Trust were deposited with the Depositary on behalf of the Escrow Agent for the benefit of the Certificateholders of such Trust.

THE COMPANY

OVERVIEW

We are the world's largest air cargo outsourcer, with an all Stage 3 Federal Aviation Administration ("FAA") noise regulation compliant fleet of Boeing 747 freighter aircraft. We provide reliable airport-to-airport cargo transportation services throughout the world to major international air carriers generally under three- to five-year fixed-rate U.S. dollar denominated contracts which typically require that we supply aircraft, crew, maintenance and insurance ("ACMI Contracts"). Our customers currently include some of the world's leading air carriers, including Alitalia, China Airlines Ltd., China Southern Airlines, Korean Airlines and Malaysian Airlines. We provide efficient, cost effective service to our customers primarily as a result of our productive work force, the outsourcing of a significant part of our regular maintenance work on a long-term, fixed-cost contractual basis and the advantageous cost economies realized in the operation of our fleet, comprised solely of Boeing 747 aircraft which are configured for service in long-haul cargo operations.

Our fleet currently includes 22 Boeing 747-200 and 12 Boeing 747-400 freighter aircraft in service. We acquired the 747-400 aircraft in 1998, 1999 and 2000 pursuant to an agreement with The Boeing Company ("Boeing") to purchase 10 new 747-400 freighter aircraft powered by engines acquired from General Electric Company, with options to purchase up to 10 additional 747-400 aircraft (the "Boeing Purchase Agreement"). In February 1999, we exercised options for two additional aircraft pursuant to the Boeing Purchase Agreement. We placed five 747-400 aircraft into service in 1998, four 747-400 aircraft into service in 1999 and three 747-400 aircraft into service in the first half of 2000.

DESCRIPTION OF THE CERTIFICATES

The following summary describes material terms of the Certificates. The summary does not purport to be complete and is qualified in its entirety by reference to all of the provisions of the Basic Agreement and to all of the provisions of the Certificates, the Trust Supplements, the Deposit Agreements, the Escrow Agreements, the Liquidity Facilities and the Intercreditor Agreement, forms of which were filed as exhibits

26

to the Registration Statement and copies of which are available as set forth under the heading "Where You Can Find More Information."

Except as otherwise indicated, the following summary relates to each of the Trusts and the Certificates issued by each Trust. The terms and conditions governing each of the Trusts will be substantially the same, except as described under "-- Subordination" below and except that the principal amount and scheduled principal repayments of the Equipment Notes held by each Trust and the interest rate and maturity date of the Equipment Notes held by each Trust will differ. The references to Sections in parentheses in the following summary are to the relevant Sections of the Basic Agreement unless otherwise indicated.

GENERAL

On January 28, 2000, Pass Through Certificates were issued representing a fractional undivided interest in one of the three classes (each, a "Class") of Atlas Air, Inc. 2000-1 Pass Through Trusts (the "Class A Trust," the "Class B Trust," and the "Class C Trust," and, collectively, the "Trusts"). The Trusts were formed pursuant to a pass through trust agreement between Atlas and Wilmington Trust Company, as trustee (the "Trustee"), dated as of January 28, 2000 (the "Basic Agreement"), and three separate supplements thereto (each, a "Trust Supplement" and, together with the Basic Agreement, collectively, the "Pass Through Trust Agreements"). The Certificates were issued by the Class A Trust, the Class B Trust, and the Class C Trust and are referred to herein as the "Class A Certificates," the "Class B Certificates" and the "Class C Certificates." As of the date of this prospectus, $124,639,000 Class A Certificates, $44,741,000 Class B Certificates and $47,937,000 Class C Certificates remain outstanding.

The New Certificates will be issued pursuant to the Pass Through Trust Agreements. The forms and terms of the New Certificates are the same in all material respects as the form and terms of the Old Certificates, except that:

- we registered the New Certificates under the Securities Act so their transfer is not restricted like the Old Certificates; and

- the New Certificates are not entitled to liquidated damages under the Registration Rights Agreement.

Each Certificate represents a fractional undivided interest in the Trust created by the Pass Through Trust Agreement pursuant to which such Certificate is issued. (Section 2.01) The Trust Property of each Trust (the "Trust Property") consists of:

- subject to the Intercreditor Agreement, Equipment Notes acquired under the Note Purchase Agreement and issued at Atlas' election in connection with the delivery of each Aircraft during the Delivery Period either (a) on a nonrecourse basis by an Owner Trustee in each separate leveraged lease transaction with respect to each Leased Aircraft to finance a portion of the purchase price of such Leased Aircraft by the Owner Trustee, in which case the applicable Leased Aircraft will be leased to Atlas or (b) on a recourse basis by Atlas in connection with each separate secured loan transaction with respect to each Owned Aircraft to finance a portion of the purchase price of such Owned Aircraft by Atlas;

- the rights of such Trust under the Intercreditor Agreement (including all monies receivable in respect of such rights);

- all monies receivable under the Liquidity Facility for such Trust; and

- funds from time to time deposited with the Trustee in accounts relating to such Trust.

27

The Certificates of each Trust have been issued in fully registered form only and are subject to the provisions described below under "-- Book Entry; Delivery and Form." New Certificates will be issued in denominations of $1,000 or integral multiples thereof. (Trust Supplement, Section 8.01(a))

The Certificates represent interests in the respective Trusts, and all payments and distributions thereon will be made only from the Trust Property of the related Trust. (Section 3.09) The Certificates do not and will not represent an interest in or obligation of Atlas, the Trustees, any of the Loan Trustees or Owner Trustees in their individual capacities, any Owner Participant or any affiliate of any thereof.

Pursuant to the Escrow Agreement applicable to each Trust, the holders of Certificates of such Trust (each, a "Certificateholder") as holders of the Escrow Receipts affixed to each Certificate are entitled to certain rights with respect to the Deposit relating to such Trust. Accordingly, any transfer of a Certificate will have the effect of transferring the corresponding rights with respect to the Deposit, and rights with respect to the Deposit may not be separately transferred by Certificateholders. Rights with respect to the Deposit and the Escrow Agreement relating to a Trust, except for the right to request withdrawals for the purchase of Equipment Notes, will not constitute Trust Property of such Trust. Payments to the Certificateholders in respect of the Deposit and the Escrow Receipts relating to a Trust will constitute payments to such Certificateholders solely in their capacity as holders of Escrow Receipts.

SUBORDINATION

The subordination terms of the Certificates vary depending upon whether a "Triggering Event" has occurred. "Triggering Event" means (x) the occurrence of an Indenture Event of Default under all Indentures resulting in a PTC Event of Default with respect to the most senior Class of Certificates then outstanding,
(y) the acceleration of all of the outstanding Equipment Notes (provided that during the Delivery Period the aggregate principal amount thereof exceeds $100 million) or (z) certain bankruptcy or insolvency events involving Atlas.

Before a Triggering Event

On each Regular Distribution Date or Special Distribution Date (each, a "Distribution Date"), so long as no Triggering Event shall have occurred (whether or not continuing), all payments received by the Subordination Agent in respect of Equipment Notes and certain other payments under the related Indenture will be distributed under the Intercreditor Agreement in the order specified under "Description of the Intercreditor Agreement -- Priority of Distributions -- Before a Triggering Event."

After a Triggering Event

Upon the occurrence of a Triggering Event and at all times thereafter, all payments received by the Subordination Agent in respect of the Equipment Notes and certain other payments will be distributed under the Intercreditor Agreement in the order specified under "Description of the Intercreditor Agreement -- Priority of Distributions -- After a Triggering Event."

Payments in respect of the Deposit relating to a Trust will not be subject to the subordination provisions of the Intercreditor Agreement.

PAYMENTS AND DISTRIBUTIONS

Payments of interest on the Deposit with respect to each Trust and payments of principal, premium (if any) and interest on the Equipment Notes or with respect to other Trust Property held in each Trust will be distributed by the Paying Agent (in the case of the Deposit) or by the Trustee (in the case of Trust Property of such Trust) to Certificateholders of such Trust on the date receipt of such payment is confirmed, except in the case of certain types of Special Payments.

The Deposit held with respect to each Trust and the Equipment Notes held in each Trust will accrue interest at the applicable rate per annum for Certificates to be issued by such Trust set forth on the cover page of this prospectus, payable on January 2 and July 2 of each year, commencing on July 2, 2000 (or, in

28

the case of Equipment Notes issued after such date, commencing with the first such date to occur after initial issuance thereof). Such interest payments will be distributed to Certificateholders of such Trust on each such date until the final Distribution Date for such Trust, subject in the case of payments on the Equipment Notes to the Intercreditor Agreement. Interest is calculated on the basis of a 360-day year consisting of twelve 30-day months.

Payments of interest applicable to the Certificates are supported by a separate Liquidity Facility provided by the applicable Liquidity Provider for the benefit of the holders of such Certificates in an aggregate amount sufficient to pay interest thereon at the Stated Interest Rate for such Trust on up to three successive Regular Distribution Dates (without regard to any future payments of principal on such Certificates), except that the Liquidity Facility with respect to such Trust does not cover interest payable by the Depositary on the Deposit relating to such Trust. The Liquidity Facility for any Class of Certificates does not provide for drawings thereunder to pay for principal of or premium on the Certificates of such Class, any interest on the Certificates of such Class in excess of the Stated Interest Rate, or, notwithstanding the subordination provisions of the Intercreditor Agreement, principal of or interest or premium on the Certificates of any other Class. Therefore, only the holders of the Certificates issued by a particular Trust will be entitled to receive and retain the proceeds of drawings under the Liquidity Facility for such Trust. See "Description of the Liquidity Facilities."

Payments of principal of the Series A, Series B and Series C Equipment Notes are scheduled to be received by the Trustee on January 2 and July 2 in certain years depending upon the terms of the Equipment Notes held in such Trust commencing on January 2, 2001 (or, in the case of Equipment Notes issued after such date, commencing with the first such date to occur after initial issuance thereof).

Scheduled payments of interest on the Deposits and of interest or principal on the Equipment Notes are herein referred to as "Scheduled Payments," and January 2 and July 2 of each year are herein referred to as "Regular Distribution Dates." See "Description of the Equipment Notes -- Principal and Interest Payments." The "Final Maturity Date" for the Class A Certificates is July 2, 2021, for the Class B Certificates is July 2, 2017 and for the Class C Certificates is July 2, 2011.

The Paying Agent with respect to each Escrow Agreement will distribute on each Regular Distribution Date to the Certificateholders of the Trust to which such Escrow Agreement relates all Scheduled Payments received in respect of the related Deposit, the receipt of which is confirmed by the Paying Agent on such Regular Distribution Date. The Trustee of each Trust will distribute, subject to the Intercreditor Agreement, on each Regular Distribution Date to the Certificateholders of such Trust all Scheduled Payments received in respect of Equipment Notes held on behalf of such Trust, the receipt of which is confirmed by the Trustee on such Regular Distribution Date. Each Certificateholder of each Trust will be entitled to receive its proportionate share, based upon its fractional interest in such Trust, of any distribution in respect of Scheduled Payments of interest on the Deposit relating to such Trust and, subject to the Intercreditor Agreement, of principal or interest on Equipment Notes held on behalf of such Trust. Each such distribution of Scheduled Payments will be made by the applicable Paying Agent or Trustee to the Certificateholders of record of the relevant Trust on the record date applicable to such Scheduled Payment subject to certain exceptions. (Sections 4.01 and 4.02; Escrow Agreement,
Section 2.03) If a Scheduled Payment is not received by the applicable Paying Agent or Trustee on a Regular Distribution Date but is received within five days thereafter, it will be distributed on the date received to such holders of record. If it is received after such five-day period, it will be treated as a Special Payment and distributed as described below.

Any payment in respect of, or any proceeds of, any Equipment Note or the Trust Indenture Estate under (and as defined in) each Leased Aircraft Indenture or Collateral under (and as defined in) any Owned Aircraft Indenture other than a Scheduled Payment (each, a "Special Payment") will be distributed on, in the case of an early redemption or a purchase of any Equipment Note, the date of such early redemption or purchase (which shall be a Business Day), and otherwise on the Business Day specified for distribution of such Special Payment pursuant to a notice delivered by each Trustee as soon as practicable after the Trustee has received funds for such Special Payment (each, a "Special

29

Distribution Date"). Any such distribution will be subject to the Intercreditor Agreement. Any unused Deposits to be distributed, together with accrued and unpaid interest thereon and any premium payable by Atlas (each, also a "Special Payment"), will be distributed on a date 15 days after the Paying Agent has received notice of the event requiring such distribution (also a "Special Distribution Date"). However, if such date is within 10 days before a Regular Distribution Date, the Special Payment shall be made on such Regular Distribution Date.

Each Paying Agent, in the case of the Deposits, and each Trustee, in the case of Trust Property, will mail a notice to the Certificateholders of the applicable Trust stating the scheduled Special Distribution Date, the related record date, the amount of the Special Payment and the reason for the Special Payment. In the case of a redemption or purchase of the Equipment Notes held in the related Trust or any distribution of unused Deposits, such notice will be mailed not less than 15 days prior to the date such Special Payment is scheduled to be distributed, and in the case of any other Special Payment, such notice will be mailed as soon as practicable after the Trustee has confirmed that it has received funds for such Special Payment. (Section 4.02(c); Escrow Agreement,
Section 2.03) Each distribution of a Special Payment, other than a final distribution, on a Special Distribution Date for any Trust will be made by the Paying Agent or the Trustee, as applicable, to the Certificateholders of record of such Trust on the record date applicable to such Special Payment. (Section 4.02(b); Escrow Agreement, Section 2.03) See "-- Indenture Defaults and Certain Rights Upon an Indenture Default" and "Description of the Equipment Notes -- Redemption."

Each Pass Through Trust Agreement requires that the Trustee establish and maintain, for the related Trust and for the benefit of the Certificateholders of such Trust, one or more non-interest bearing accounts (the "Certificate Account") for the deposit of payments representing Scheduled Payments received by such Trustee. Each Pass Through Trust Agreement requires that the Trustee establish and maintain, for the related Trust and for the benefit of the Certificateholders of such Trust, one or more accounts (the "Special Payments Account") for the deposit of payments representing Special Payments received by such Trustee, which shall be non-interest bearing except in certain circumstances where the Trustee may invest amounts in such account in certain permitted investments. Pursuant to the terms of each Pass Through Trust Agreement, the Trustee is required to deposit any Scheduled Payments relating to the applicable Trust received by it in the Certificate Account of such Trust and to deposit any Special Payments so received by it in the Special Payments Account of such Trust. (Section 4.01) All amounts so deposited will be distributed by the Trustee on a Regular Distribution Date or a Special Distribution Date, as appropriate. (Section 4.02)

Each Escrow Agreement requires that the Paying Agent establish and maintain, for the benefit of the Receiptholders, one or more accounts (the "Paying Agent Account"), which shall be non-interest bearing. Pursuant to the terms of the Escrow Agreement, the Paying Agent is required to deposit interest on the Deposit relating to such Trust and any unused Deposits withdrawn by the Escrow Agent in the Paying Agent Account. All amounts so deposited will be distributed by the Paying Agent on a Regular Distribution Date or Special Distribution Date, as appropriate.

The final distribution for each Trust will be made only upon presentation and surrender of the Certificates for such Trust at the office or agency of the Trustee specified in the notice given by the Trustee of such final distribution. The Trustee will mail such notice of the final distribution to the Certificateholders of such Trust, specifying the date set for such final distribution and the amount of such distribution. (Section 11.01) See "-- Termination of the Trusts" below. Distributions in respect of Certificates issued in global form will be made as described in "-- Book-Entry; Delivery and Form" below.

If any Distribution Date is a Saturday, Sunday or other day on which commercial banks are authorized or required to close in New York, New York, Wilmington, Delaware, Denver, Colorado, or Salt Lake City, Utah (any other day being a "Business Day"), distributions scheduled to be made on such Regular Distribution Date or Special Distribution Date will be made on the next succeeding Business Day without additional interest.

POOL FACTORS

The "Pool Balance" for each Trust or for the Certificates issued by any Trust indicates, as of any date, the original aggregate face amount of the Certificates of such Trust less the aggregate amount of all payments made in respect of the Certificates of such Trust or in respect of the Deposit relating to such Trust other than payments made in respect of interest or premium or reimbursement of any costs and expenses in connection therewith. The Pool Balance for each Trust or for the Certificates issued by any Trust as of any Distribution Date will be computed after giving effect to any special distribution with respect to the unused Deposit, payment of principal of the Equipment Notes or payment with respect to other Trust Property held in such Trust and the distribution thereof to be made on that date. (Trust Supplement,
Section 2.01)

The "Pool Factor" for each Trust as of any Distribution Date will be the quotient (rounded to the seventh decimal place) computed by dividing (i) the Pool Balance by (ii) the original aggregate face amount of the Certificates of such Trust. The Pool Factor for each Trust or for the Certificates issued by any Trust as of any Distribution Date will be computed after giving effect to any special distribution with respect to the unused Deposit, payment of principal of the Equipment Notes or payment with respect to other Trust Property held in such Trust and the distribution thereof to be made on that date. (Trust Supplement,
Section 2.01) The Pool Factor for each Trust was 1.0000000 on the date of issuance of the Certificates; thereafter, the Pool Factor for each Trust declines as described herein to reflect reductions in the Pool Balance of such Trust. The amount of a Certificateholder's pro rata share of the Pool Balance of a Trust can be determined by multiplying the par value of the holder's Certificate of such Trust by the Pool Factor for such Trust as of the applicable Distribution Date. Notice of the Pool Factor and the Pool Balance for each Trust will be mailed to Certificateholders of such Trust on each Regular Distribution Date and Special Distribution Date. (Trust Supplement, Section 3.02)

The following table sets forth an illustrative aggregate principal amortization schedule for the Equipment Notes held in each Trust (the "Assumed Amortization Schedule") and resulting Pool Factors with respect to such Trust. The actual aggregate principal amortization schedule applicable to the Class A, Class B or Class C Trust and the resulting Pool Factors with respect to each such Trust may differ from those set forth below, since the amortization schedule for the Series A, Series B or Series C Equipment Notes issued with respect to an Aircraft may vary from such illustrative amortization schedule so long as it complies with the Mandatory Economic Terms. Moreover, the scheduled distribution of principal payments for any Trust would be affected if any Equipment Notes held in such Trust are redeemed or purchased or if a default in payment on such Equipment Notes occurred. In addition, the table set forth below assumes that each Aircraft is delivered in the month scheduled for its delivery (see "Description of the Aircraft and the Appraisals -- The Appraisals" for the delivery schedule) and that Equipment Notes in the maximum principal amount in respect of all of the Aircraft are purchased by the Trusts. Actual circumstances may vary from these assumptions, which would result in differences in the aggregate principal amortization schedule applicable to a Trust and in the resulting Pool Factors.

The final schedule of principal payments and the resulting schedule of Pool Balances and Pool Factors may change from that set forth above as a result of any reoptimization. Such reoptimization may occur at any time prior to July 2, 2001. In addition, the Pool Factor and Pool Balance of each Trust will be recomputed if there has been an early redemption, purchase, or default in the payment of principal or interest in respect of one or more of the Equipment Notes held in a Trust, as described in "-- Indenture Defaults and Certain Rights Upon an Indenture Default" and "Description of the Equipment Notes -- Redemption," or a special distribution attributable to unused Deposits, as described in "Description of the Deposit Agreements." If (i) any such change in the scheduled repayments or (ii) any such redemption, purchase, default or special distribution occurs, the Pool Factors and the Pool Balances of each Trust so affected will be recomputed after giving effect thereto and notice thereof will be mailed to the Certificateholders of such Trust promptly after any such change in scheduled repayments or after the occurrence of any event described in clause (ii), as the case may be.

REPORTS TO CERTIFICATEHOLDERS

On each Distribution Date, the applicable Paying Agent and Trustee will include with each distribution by it of a Scheduled Payment or Special Payment to Certificateholders of the related Trust a statement, setting forth the following information (per $1,000 aggregate principal amount of Certificate for such Trust, as to (2), (3), (4) and (5) below):

(1) the aggregate amount of such funds distributed on such Distribution Date under the Pass Through Trust Agreement and the Escrow Agreement, indicating the amount allocable to each source;

(2) the amount of such distribution under the Pass Through Trust Agreement allocable to principal and the amount allocable to premium (including any premium paid by Atlas with respect to unused Deposits), if any;

(3) the amount of such distribution under the Pass Through Trust Agreement allocable to interest;

(4) the amount of such distribution under the Escrow Agreement allocable to interest;

(5) the amount of such distribution under the Escrow Agreement allocable to unused Deposits (if any); and

(6) the Pool Balance and the Pool Factor for such Trust. (Trust Supplement, Section 3.02(a))

So long as the Certificates are registered in the name of DTC or its nominee, on the record date prior to each Distribution Date, the applicable Trustee will request from DTC a securities position listing setting forth the names of all DTC Participants reflected on DTC's books as holding interests in the Certificates

32

on such record date. On each Distribution Date, the applicable Paying Agent and Trustee will mail to each such DTC Participant the statement described above and will make available additional copies as requested by such DTC Participant for forwarding to holders of interests in the Certificates. (Trust Supplement,
Section 3.02(a))

In addition, after the end of each calendar year, the applicable Trustee and Paying Agent will furnish to each Certificateholder of each Trust at any time during the preceding calendar year a report containing the sum of the amounts determined pursuant to clauses (1), (2), (3), (4) and (5) above with respect to the Trust for such calendar year or, if such person was a Certificateholder during only a portion of such calendar year, for the applicable portion of such calendar year, and such other items as are readily available to such Trustee and which a Certificateholder shall reasonably request as necessary for the purpose of such Certificateholder's preparation of its U.S. federal income tax returns. (Trust Supplement, Section 3.02(b)) Such report and such other items shall be prepared on the basis of information supplied to the applicable Trustee by the DTC Participants and will be delivered by such Trustee to such DTC Participants to be available for forwarding by such DTC Participants to holders of interests in the Certificates in the manner described above. (Trust Supplement, Section 3.02(b)) At such time, if any, as the Certificates are issued in the form of definitive certificates, the applicable Paying Agent and Trustee will prepare and deliver the information described above to each Certificateholder of record of each Trust as the name and period of ownership of such Certificateholder appear on the records of the registrar of the Certificates.

INDENTURE DEFAULTS AND CERTAIN RIGHTS UPON AN INDENTURE DEFAULT

An event of default under an Indenture (an "Indenture Event of Default") will, with respect to the Leased Aircraft Indentures, include an event of default under the related Lease (a "Lease Event of Default"). See "Description of the Equipment Notes -- Indenture Event of Defaults, Notice and Waiver." Since the Equipment Notes issued under an Indenture will be held in more than one Trust, a continuing Indenture Event of Default under such Indenture would affect the Equipment Notes held by each Trust. There are no cross-default provisions in the Indentures or in the Leases (unless otherwise agreed between an Owner Participant and Atlas). Consequently, events resulting in an Indenture Event of Default under any particular Indenture may or may not result in an Indenture Event of Default under any other Indenture, and a Lease Event of Default under any particular Lease may or may not constitute a Lease Event of Default under any other Lease. If an Indenture Event of Default occurs in fewer than all of the Indentures, notwithstanding the treatment of Equipment Notes issued under any Indenture under which an Indenture Event of Default has occurred, payments of principal and interest on the Equipment Notes will continue to be distributed to the holders of the Certificates as originally scheduled, subject to the Intercreditor Agreement. See "Description of the Intercreditor Agreement -- Priority of Distributions."

With respect to each Leased Aircraft, the applicable Owner Trustee and Owner Participant, under the related Leased Aircraft Indenture, will have the right under certain circumstances to cure Indenture defaults that result from the occurrence of a Lease Event of Default under the related Lease. If the Owner Trustee or the Owner Participant exercises any such cure right, the Indenture default will be deemed to have been cured.

In the event that the same institution acts as Trustee of multiple Trusts, in the absence of instructions from the Certificateholders of any such Trust, such Trustee could be faced with a potential conflict of interest upon an Indenture Event of Default. In such event, each Trustee has indicated that it would resign as Trustee of one or all such Trusts, and a successor trustee would be appointed in accordance with the terms of the applicable Pass Through Trust Agreement. Wilmington Trust Company will be the initial Trustee under each Trust.

Upon the occurrence and continuation of an Indenture Event of Default, the Controlling Party will direct the Indenture Trustee under such Indenture in the exercise of remedies thereunder and may accelerate and sell all (but not less than all) of the Equipment Notes issued under such Indenture to any person, subject to certain limitations. See "Description of the Intercreditor Agreement -- Intercreditor

33

Rights -- Sale of Equipment Notes or Aircraft." The proceeds of such sale will be distributed pursuant to the provisions of the Intercreditor Agreement. Any such proceeds so distributed to any Trustee upon any such sale shall be deposited in the applicable Special Payments Account and shall be distributed to the Certificateholders of the applicable Trust on a Special Distribution Date. (Sections 4.01 and 4.02) The market for Equipment Notes at the time of the existence of an Indenture Event of Default may be very limited and there can be no assurance as to the price at which they could be sold. If any such Equipment Notes are sold for less than their outstanding principal amount, certain Certificateholders will receive a smaller amount of principal distributions than anticipated and will not have any claim for the shortfall against Atlas, any Liquidity Provider, any Owner Trustee, any Owner Participant or any Trustee.

Any amount, other than Scheduled Payments received on a Regular Distribution Date or within five days thereafter, distributed to the Trustee of any Trust by the Subordination Agent on account of any Equipment Note or Trust Indenture Estate under (and as defined in) any Leased Aircraft Indenture or Collateral under (and as defined in) any Owned Aircraft Indenture held in such Trust following an Indenture Event of Default will be deposited in the Special Payments Account for such Trust and will be distributed to the Certificateholders of such Trust on a Special Distribution Date. (Sections 4.01 and 4.02) In addition, if, following an Indenture Event of Default under any Leased Aircraft Indenture, the applicable Owner Participant or Owner Trustee exercises its option to redeem or purchase the outstanding Equipment Notes issued under such Leased Aircraft Indenture, the price paid by such Owner Participant or Owner Trustee for the Equipment Notes issued under such Leased Aircraft Indenture and distributed to such Trust by the Subordination Agent will be deposited in the Special Payments Account for such Trust and will be distributed to the Certificateholders of such Trust on a Special Distribution Date. (Sections 4.01 and 4.02)

Any funds representing payments received with respect to any defaulted Equipment Notes, or the proceeds from the sale of any Equipment Notes, held by the Trustee in the Special Payments Account for such Trust will, to the extent practicable, be invested and reinvested by such Trustee in certain permitted investments pending the distribution of such funds on a Special Distribution Date. (Section 4.04) Such permitted investments will be defined as obligations of the United States or agencies or instrumentalities thereof for the payment of which the full faith and credit of the United States is pledged and which mature in not more than 60 days or such lesser time as is required for the distribution of any such funds on a Special Distribution Date. (Section 1.01)

Each Pass Through Trust Agreement provides that the Trustee of the related Trust will, within 90 days after the occurrence of any default known to the Trustee, give to the Certificateholders of such Trust notice, transmitted by mail, of such uncured or unwaived defaults with respect to such Trust known to it, provided that, except in the case of default in a payment of principal, premium, if any, or interest on any of the Equipment Notes held in such Trust, the applicable Trustee will be protected in withholding such notice if it in good faith determines that the withholding of such notice is in the interests of such Certificateholders. (Section 7.02) The term "default" as used in this paragraph only with respect to any Trust means the occurrence of an Indenture Event of Default under any Indenture pursuant to which Equipment Notes held by such Trust were issued, as described above, except that in determining whether any such Indenture Event of Default has occurred, any grace period or notice in connection therewith will be disregarded.

Each Pass Through Trust Agreement contains a provision entitling the Trustee of the related Trust, subject to the duty of such Trustee during a default to act with the required standard of care, to be offered reasonable security or indemnity by the holders of the Certificates of such Trust before proceeding to exercise any right or power under such Pass Through Trust Agreement at the request of such Certificateholders. (Section 7.03(e))

Subject to certain qualifications set forth in each Pass Through Trust Agreement and to the Intercreditor Agreement, the Certificateholders of each Trust holding Certificates evidencing fractional undivided interests aggregating not less than a majority in interest in such Trust will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee

34

with respect to such Trust or pursuant to the terms of the Intercreditor Agreement, or exercising any trust or power conferred on such Trustee under such Pass Through Trust Agreement or the Intercreditor Agreement, including any right of such Trustee as Controlling Party under the Intercreditor Agreement or as holder of the Equipment Notes. (Section 6.04)

In certain cases, the holders of the Certificates of a Trust evidencing fractional undivided interests aggregating not less than a majority in interest of such Trust may on behalf of the holders of all the Certificates of such Trust waive any past Indenture Event of Default and its consequences under any Indenture pursuant to which Equipment Notes held by such Trust were issued or, if the Trustee of such Trust is the Controlling Party, may direct the Trustee to instruct the applicable Loan Trustee to waive any past Indenture Default and its consequences, except (i) a default in the deposit of any Scheduled Payment or Special Payment or in the distribution thereof, (ii) a default in payment of the principal, premium, if any, or interest with respect to any of the Equipment Notes and (iii) a default in respect of any covenant or provision of the Pass Through Trust Agreement that cannot be modified or amended without the consent of each Certificateholder of such Trust affected thereby. (Section 6.05) Each Indenture will provide that, with certain exceptions, the holders of the majority in aggregate unpaid principal amount of the Equipment Notes issued thereunder may on behalf of all such holders waive any past default or Indenture Event of Default thereunder. Notwithstanding such provisions of the Indentures, pursuant to the Intercreditor Agreement only the Controlling Party will be entitled to waive any such past default or Indenture Event of Default.

PURCHASE RIGHTS OF CERTIFICATEHOLDERS

Upon the occurrence and during the continuation of a Triggering Event, with 10 days' written notice to the Trustee and each Certificateholder of the same Class:

- the Class B Certificateholders will have the right to purchase all, but not less than all, of the Class A Certificates;

- the Class C Certificateholders will have the right to purchase all, but not less than all, of the Class A and Class B Certificates; and

- if the Class D Certificates are issued, the Class D Certificateholders shall have the right to purchase all, but not less than all, of the Class A, Class B and Class C Certificates.

In each case the purchase price will be equal to the Pool Balance of the relevant Class or Classes of Certificates plus accrued and unpaid interest thereon to the date of purchase, without premium, but including any other amounts due to the Certificateholders of such Class or Classes. (Trust Supplement, Section 4.01) In each case, if prior to the end of the 10-day period, any other Certificateholder of the same Class notifies the purchasing Certificateholder that the other Certificateholder wants to participate in such purchase, then such other Certificateholder may join with the purchasing Certificateholder to purchase the Certificates pro rata based on the interest in the Trust held by each Certificateholder.

PTC EVENT OF DEFAULT

A Pass Through Certificate Event of Default (a "PTC Event of Default") is defined under the Pass Through Trust Agreements as the failure to pay:

- the outstanding Pool Balance of the applicable Class of Certificates within 10 Business Days of the Final Maturity Date for such Class; or

- interest due on such Class of Certificates within 10 Business Days of any Distribution Date (unless the Subordination Agent shall have made Interest Drawings, or withdrawals from the Cash Collateral Accounts for such Class of Certificates, with respect thereto in an aggregate amount sufficient to pay such interest and shall have distributed such amount to the Trustee entitled thereto).

35

Any failure to make expected principal distributions with respect to any Class of Certificates on any Regular Distribution Date (other than the Final Maturity Date) will not constitute a PTC Event of Default with respect to such Certificates. A PTC Event of Default with respect to the most senior outstanding Class of Certificates resulting from an Indenture Event of Default under all Indentures will constitute a Triggering Event. See "Description of the Intercreditor Agreement -- Priority of Distributions" for a discussion of the consequences of the occurrence of a Triggering Event.

MERGER, CONSOLIDATION AND TRANSFER OF ASSETS

Atlas is prohibited from consolidating with or merging into any other corporation or transferring substantially all of its assets as an entirety to any other corporation unless:

- the surviving successor or transferee corporation is validly existing under the laws of the United States or any state thereof;

- the surviving successor or transferee corporation is a "citizen of the United States" (as defined in Title 49 of the United States Code relating to aviation (the "Transportation Code")) holding an air carrier operating certificate issued by the Secretary of Transportation pursuant to Chapter 447 of Title 49, United States Code, if, and so long as, such status is a condition of entitlement to the benefits of Section 1110 of the Bankruptcy Code;

- the surviving successor or transferee corporation expressly assumes all of the obligations of Atlas contained in any Pass Through Trust Agreement, the Note Purchase Agreement, the Owned Aircraft Indentures, the Participation Agreements and the Leases, and any other operative documents; and

- Atlas delivers a certificate and an opinion or opinions of counsel indicating that such transaction, in effect, complies with such conditions.

In addition, after giving effect to such transaction, no Lease Event of Default, in the case of a Leased Aircraft, or Indenture Default, in the case of an Owned Aircraft, shall have occurred and be continuing. (Section 5.02; Leases,
Section 13.02; Owned Aircraft Indentures, Section 4.07)

The Pass Through Trust Agreements, the Note Purchase Agreement, the Indentures, the Participation Agreements and the Leases do not contain any covenants or provisions which may afford the applicable Trustee or Certificateholders protection in the event of a highly leveraged transaction, including transactions effected by management or affiliates, which may or may not result in a change in control of Atlas.

MODIFICATIONS OF THE PASS THROUGH TRUST AGREEMENTS AND CERTAIN OTHER AGREEMENTS

Each Pass Through Trust Agreement contains provisions permitting, at our request, the execution of amendments or supplements to such Pass Through Trust Agreement or, if applicable, to the Deposit Agreements, the Escrow Agreements, the Intercreditor Agreement, the Note Purchase Agreement or any Liquidity Facility, without the consent of the holders of any of the Certificates of such Trust:

- to provide for the formation of a Trust to issue additional classes of certificates and to enter into Trust Supplements setting forth the terms of any such class of certificates;

- to evidence the succession of another corporation to Atlas and the assumption by such corporation of Atlas' obligations under such Pass Through Trust Agreement, Deposit Agreement, Escrow Agreement, Note Purchase Agreement or Liquidity Facility;

- to add to the covenants of Atlas for the benefit of holders of such Certificates or to surrender any right or power conferred upon Atlas in such Pass Through Trust Agreement, Deposit Agreement, Escrow Agreement, Intercreditor Agreement, Note Purchase Agreement or Liquidity Facility;

36

- to correct or supplement any provision of such Pass Through Trust Agreement, the Deposit Agreement, Escrow Agreement, Intercreditor Agreement, Note Purchase Agreement or Liquidity Facility which may be defective or inconsistent with any other provision in such Pass Through Trust Agreement, Deposit Agreement, Escrow Agreement, Intercreditor Agreement, Note Purchase Agreement or Liquidity Facility, as applicable, or to cure any ambiguity or to modify any other provision with respect to matters or questions arising under such Pass Through Trust Agreement, Deposit Agreement, Escrow Agreement, Intercreditor Agreement, Note Purchase Agreement or Liquidity Facility, provided that such action shall not materially adversely affect the interests of the holders of such Certificates;

- to correct any mistake in such Pass Through Trust Agreement, Deposit Agreement, Escrow Agreement, Intercreditor Agreement, Note Purchase Agreement or Liquidity Facility; or, as provided in the Intercreditor Agreement, to give effect to or provide for a Replacement Facility;

- to comply with any requirement of the SEC, any applicable law, rules or regulations of any exchange or quotation system on which the Certificates are listed, or any regulatory body;

- to modify, eliminate or add to the provisions of such Pass Through Trust Agreement, Deposit Agreement, Escrow Agreement, Intercreditor Agreement, Note Purchase Agreement or Liquidity Facility to such extent as shall be necessary to continue the qualification of such Pass Through Trust Agreement (including any supplemental agreement) under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), or any similar federal statute enacted after the execution of such Pass Through Trust Agreement, and to add to such Pass Through Trust Agreement, Deposit Agreement, Escrow Agreement, Intercreditor Agreement, Note Purchase Agreement or Liquidity Facility such other provisions as may be expressly permitted by the Trust Indenture Act; and

- to evidence and provide for the acceptance of appointment under such Pass Through Trust Agreement, Deposit Agreement, Escrow Agreement, Intercreditor Agreement, Note Purchase Agreement or Liquidity Facility by a successor Trustee and to add to or change any of the provisions of such Pass Through Trust Agreement, Deposit Agreement, Escrow Agreement, Intercreditor Agreement, Note Purchase Agreement or Liquidity Facility as shall be necessary to provide for or facilitate the administration of the Trusts by more than one Trustee.

In each case, such modification or supplement may not adversely affect the status of the Trust as a grantor trust under Subpart E, Part I of Subchapter J of Chapter 1 of Subtitle A of the Internal Revenue Code of 1986, as amended (the "Code"), for U.S. federal income tax purposes. (Section 9.01)

Each Pass Through Trust Agreement also contains provisions permitting the execution, with the consent of the holders of the Certificates of the related Trust evidencing fractional undivided interests aggregating not less than a majority in interest of such Trust, and with the consent of the applicable Owner Trustee, of amendments or supplements adding any provisions to or changing or eliminating any of the provisions of such Pass Through Trust Agreement, the Deposit Agreements, the Escrow Agreements, the Intercreditor Agreement, the Note Purchase Agreement or any Liquidity Facility to the extent applicable to such Certificateholders or of modifying the rights and obligations of such Certificateholders under such Pass Through Trust Agreement, the Deposit Agreements, the Escrow Agreements, the Intercreditor Agreement, the Note Purchase Agreement or any Liquidity Facility. However, no such amendment or supplement may, without the consent of the holder of each Certificate adversely affected thereby:

- reduce in any manner the amount of, or delay the timing of, any receipt by the Trustee (or, with respect to the Deposit, the Receiptholders) of payments with respect to the Deposit, the Equipment Notes held in such Trust or distributions in respect of any Certificate related to such Trust, or change the date or place of any payment in respect of any Certificate, or make distributions payable in coin or currency other than that provided for in such Certificates, or impair the right of any Certificateholder of such Trust to institute suit for the enforcement of any such payment when due;

37

- permit the disposition of any Equipment Note held in such Trust, except as provided in such Pass Through Trust Agreement, or otherwise deprive such Certificateholder of the benefit of the ownership of the applicable Equipment Notes;

- alter the priority of distributions specified in the Intercreditor Agreement in a manner materially adverse to such Certificateholders;

- reduce the percentage of the aggregate fractional undivided interests of the Trust provided for in such Pass Through Trust Agreement, the consent of the holders of which is required for any such supplemental trust agreement or for any waiver provided for in such Pass Through Trust Agreement; or

- modify any of the provisions relating to the rights of the Certificateholders in respect of the waiver of events of default or receipt of payment. (Section 9.02; Trust Supplement, Section 6.02)

In the event that a Trustee, as holder (or beneficial owner through the Subordination Agent) of any Equipment Note in trust for the benefit of the Certificateholders of the relevant Trust or as Controlling Party under the Intercreditor Agreement, receives (directly or indirectly through the Subordination Agent) a request for a consent to any amendment, modification, waiver or supplement under any Indenture, any Participation Agreement, any Lease, any Equipment Note or any other related document, the Trustee shall forthwith send a notice of such proposed amendment, modification, waiver or supplement to each Certificateholder of the relevant Trust as of the date of such notice. The Trustee shall request from the Certificateholders a direction as to:

- whether or not to take or refrain from taking (or direct the Subordination Agent to take or refrain from taking) any action which a holder of such Equipment Note or the Controlling Party has the option to take;

- whether or not to give or execute (or direct the Subordination Agent to give or execute) any waivers, consents, amendments, modifications or supplements as a holder of such Equipment Note or as Controlling Party; and

- how to vote (or direct the Subordination Agent to vote) any Equipment Note if a vote has been called for with respect thereto.

Provided such a request for Certificateholder direction shall have been made, in directing any action or casting any vote or giving any consent as the holder of any Equipment Note (or in directing the Subordination Agent in any of the foregoing):

- other than as Controlling Party, the Trustee shall vote for or give consent to any such action with respect to such Equipment Note in the same proportion as that of (x) the aggregate face amount of all Certificates actually voted in favor of or for giving consent to such action by such direction of Certificateholders to (y) the aggregate face amount of all outstanding certificates of the relevant Trust; and

- as the Controlling Party, the Trustee shall vote as directed in such Certificateholder direction by the Certificateholders evidencing fractional undivided interests aggregating not less than a majority in interest in the relevant Trust.

For purposes of the immediately preceding sentence, a Certificate shall have been "actually voted" if the Certificateholder has delivered to the Trustee an instrument evidencing such Certificateholder's consent to such direction prior to one Business Day before the Trustee directs such action or casts such vote or gives such consent. Notwithstanding the foregoing, but subject to certain rights of the Certificateholders under the relevant Pass Through Trust Agreement and subject to the Intercreditor Agreement, the Trustee may, in its own discretion and at its own direction, consent and notify the relevant Loan Trustee of such consent (or direct the Subordination Agent to consent and notify the relevant Loan Trustee of such consent) to any amendment, modification, waiver or supplement under the relevant Indenture,

38

Participation Agreement or Lease, any relevant Equipment Note or any other related document, if an Indenture Event of Default under any Indenture shall have occurred and be continuing, or if such amendment, modification, waiver or supplement will not materially adversely affect the interests of the Certificateholders. (Section 10.01)

OBLIGATION TO PURCHASE EQUIPMENT NOTES

The Class A, Class B and Class C Trustees, respectively, are obligated to purchase the Series A, Series B and Series C Equipment Notes issued with respect to each Aircraft, subject in each case to the terms and conditions of a note purchase agreement (the "Note Purchase Agreement"). Under the Note Purchase Agreement, Atlas agrees to finance each Aircraft in the manner provided therein and in connection therewith will have the option of entering into a leveraged lease financing or a secured debt financing with respect to each Aircraft. In addition, Atlas may elect to convert an Owned Aircraft to a Leased Aircraft at any time by entering into a sale/leaseback transaction.

- If Atlas chooses to enter into a leveraged lease financing with respect to an Aircraft (such Aircraft, a "Leased Aircraft"), the Note Purchase Agreement provides for the relevant parties to enter into a participation agreement (each, a "Participation Agreement"), a Lease and an indenture (each, a "Leased Aircraft Indenture") relating to the financing of such Leased Aircraft.

- If Atlas chooses to enter into a secured debt financing with respect to an Aircraft (such Aircraft, an "Owned Aircraft"), the Note Purchase Agreement provides for the relevant parties to enter into a participation agreement (each, a "Participation Agreement") and an indenture (each an "Owned Aircraft Indenture" and together with the other Owned Aircraft Indentures and the Leased Aircraft Indentures, the "Indentures") relating to the financing of such Owned Aircraft.

The description of such agreements in this prospectus is based on the forms of such agreements to be utilized pursuant to the Note Purchase Agreement. In the case of a Leased Aircraft, the terms of the agreements actually entered into may differ from the forms of such agreements and, consequently, may differ from the description of such agreements contained in this prospectus. See "Description of the Equipment Notes." However, under the Note Purchase Agreement, the terms of such agreements are required to (a) contain the Mandatory Document Terms and (b) not vary the Mandatory Economic Terms. In addition, Atlas is obligated (a) to certify to the Trustees that any such modifications do not materially and adversely affect the Certificateholders and
(b) to obtain written confirmation from each Rating Agency that the use of versions of such agreements modified in any material respect (other than modifications affecting only the Owner Participant) will not result in a withdrawal, suspension or downgrading of the rating of any Class of Certificates. Further, under the Note Purchase Agreement, it is a condition precedent to the obligation of each Trustee to purchase the Equipment Notes related to the financing of an Aircraft that no Triggering Event shall have occurred. The Trustees will have no right or obligation to purchase Equipment Notes after the Delivery Period Termination Date.

MANDATORY ECONOMIC TERMS AND MANDATORY DOCUMENT TERMS

The "Mandatory Economic Terms," as defined in the Note Purchase Agreement, require, among other things, that:

- the aggregate principal amount of all the Equipment Notes issued with respect to an Aircraft not exceed the maximum principal amount of Equipment Notes indicated for each such Aircraft as set forth in "Summary -- Equipment Notes and the Aircraft" under the column "Maximum Principal Amount of Equipment Notes";

- the initial LTV with respect to an Aircraft (with the value of any Aircraft for these purposes to equal the value (the "Assumed Appraised Value") for such Aircraft set forth in "Summary -- Equipment Notes and the Aircraft" under the column "Appraised Base Value"), not exceed 39.0% in the case of Series A Equipment Notes, 53.0% in the case of Series B Equipment Notes and 68.0% in the case of Series C Equipment Notes;

39

- the LTV for each series of Equipment Notes issued in respect of each Aircraft (computed as of the date of issuance thereof on the basis of the Assumed Appraised Value of such Aircraft and the Depreciation Assumption) not exceed as of any Regular Distribution Date thereafter (assuming no default in the payment of the Equipment Notes) 39.0% in the case of the Series A Equipment Notes, 53.0% in the case of the Series B Equipment Notes and 68.0% in the case of the Series C Equipment Notes.

- the initial average life of each series of Equipment Notes for any Aircraft from the Issuance Date shall be as follows:

Series A Equipment Notes: not less than 11.0 years or more than 13.5 years
Series B Equipment Notes: not less than 6.5 years or more than 9.5 years Series C Equipment Notes: not less than 2.5 years or more than 4.25 years

- as of the Delivery Period Termination Date, the average life of each Class of Certificates shall be as follows, in each case from the Issuance Date (computed without regard to the acceleration of any Equipment Notes and after giving effect to any special distribution on the Certificates thereafter required in respect of unused Deposits):

Class A Certificates: not less than 11.5 years or more than 13.5 years Class B Certificates: not less than 7.5 years or more than 9.0 years Class C Certificates: not less than 3.0 years or more than 4.0 years

- the final expected Distribution Date of each Class of Certificates shall be as set forth on the cover page of this prospectus;

- the original aggregate principal amount of all of the Equipment Notes of each Series shall not exceed the original aggregate face amount of the Certificates issued by the corresponding Trust;

- the interest rate applicable to each Series of Equipment Notes must be equal to the rate applicable to the Certificates issued by the corresponding Trust;

- the payment dates for the Equipment Notes and basic rent under the Leases must be January 2 and July 2; provided however that rent under a Lease may also be paid at Atlas' election upon the commencement of such Lease and on any other date agreed between Atlas and the Owner Participant that occurs after the latest maturity date of the Equipment Notes issued in connection with the acquisition of the Aircraft to which the Lease relates;

- rent, stipulated loss values and termination values under the Leases must be sufficient to pay amounts due with respect to the related Equipment Notes;

- the amounts payable under the all-risk aircraft hull insurance maintained with respect to each Aircraft must be sufficient to pay the applicable stipulated loss value, or, in the case of Owned Aircraft, unpaid principal amount of the related Equipment Notes, subject to certain rights of self-insurance; and

- (a) the past due rate in the Indentures and the Leases, (b) the Make-Whole Premium payable under the Indentures, (c) the provisions relating to the redemption and purchase of Equipment Notes in the Indentures, (d) the minimum liability insurance amount on Aircraft in the Leases subject to certain rights of self-insurance, (e) the interest rate payable, if any, with respect to stipulated loss value in the Leases, and
(f) the indemnification of the Loan Trustees, Subordination Agent, Liquidity Providers (including MSDW so long as MSCS is a Liquidity Provider), Trustees, Escrow Agents and registered holders of the Equipment Notes (in such capacity, the "Note Holders") with respect to certain taxes and expenses, in each case be provided as set forth in the form of Participation Agreements, Lease and Indentures (collectively, the "Aircraft Operative Agreements").

40

The "Mandatory Document Terms" prohibit modifications in any material adverse respect to certain specified provisions of the Aircraft Operative Agreements annexed to the Note Purchase Agreement, as follows:

- In the case of the Indentures, the following modifications are prohibited:

(i) to the Granting Clause of the Indentures so as to deprive the Note Holders of a first priority security interest in the Aircraft, certain of Atlas' rights under its purchase agreement with the Aircraft manufacturer and, in the case of a Leased Aircraft, the Lease or to eliminate the obligations intended to be secured thereby;

(ii) to certain provisions relating to the issuance, redemption, purchase, payments, and ranking of the Equipment Notes (including the obligation to pay the Make-Whole Premium in certain circumstances);

(iii) to certain provisions regarding Indenture Defaults, remedies relating thereto and rights of the Owner Trustee and Owner Participant in such circumstances;

(iv) to certain provisions relating to any replaced airframe or engines with respect to an Aircraft; and

(v) to the provision that New York law will govern the Indentures.

- In the case of the Lease, the following modifications are prohibited:

(i) to certain provisions regarding the obligation of Atlas to pay basic rent, stipulated loss value and termination value to the Leased Aircraft Trustee;

(ii) to certain provisions regarding the obligation of Atlas to record the Leased Aircraft Indenture with the Federal Aviation Administration and to maintain such Indenture as a first-priority perfected mortgage on the related Aircraft;

(iii) to certain provisions relating to the obligation of Atlas to furnish certain opinions with respect to a replacement airframe;

(iv) to certain provisions relating to the obligation of Atlas to consent to the assignment of the Lease by the Owner Trustee as collateral under the Leased Aircraft Indenture; and

(v) modifications which would either alter the provision that New York law will govern the Lease or would deprive the Loan Trustee of rights expressly granted to it under the Leases.

- In the case of the Participation Agreement, the following modifications are prohibited:

(i) to certain conditions to the obligations of the Trustees to purchase the Equipment Notes issued with respect to an Aircraft involving good title to such Aircraft, obtaining a certificate of airworthiness with respect to such Aircraft, entitlement to the benefits of Section 1110 with respect to such Aircraft and filings of certain documents with the Federal Aviation Administration;

(ii) to the provisions restricting the Note Holder's ability to transfer such Equipment Notes;

(iii) to certain provisions requiring the delivery of legal opinions; and

(iv) to the provision that New York law will govern the Participation Agreement.

- In the case of all of the Aircraft Operative Agreements, modifications are prohibited in any material adverse respect as regards the interest of the Note Holders, the Subordination Agent, the Liquidity Providers or the Loan Trustees in the definition of Make-Whole Premium.

Notwithstanding the foregoing, any such Mandatory Document Term may be modified to correct or supplement any such provision which may be defective or to cure any ambiguity or correct any mistake,

41

provided that any such action shall not materially adversely affect the interests of the Note Holders, the Subordination Agent, the Liquidity Providers, the Loan Trustees or the Certificateholders.

POSSIBLE ISSUANCE OF SERIES D EQUIPMENT NOTES

Atlas may elect to issue Series D Equipment Notes in connection with the financing of Owned Aircraft, which will be funded from sources other than the original placement of the Old Certificates. Atlas may elect to fund the sale of the Series D Equipment Notes through the sale of Pass Through Certificates (the "Class D Certificates") issued by a Class D Atlas Air 2000-1 Pass Through Trust (the "Class D Trust"). Atlas will not issue any Series D Equipment Notes at any time prior to the consummation of the original placement of the Old Certificates. The Note Purchase Agreement provides that Atlas' ability to issue any Series D Equipment Notes is contingent upon its obtaining written confirmation from each Rating Agency that the issuance of such Series D Equipment Notes will not result in a withdrawal or downgrading of the rating of any Class of Certificates. If the Class D Certificates are issued, the Class D Trustee will become a party to the Intercreditor Agreement. See "Description of the Intercreditor Agreement."

TERMINATION OF THE TRUSTS

The obligations of Atlas and the applicable Trustee with respect to a Trust will terminate upon the distribution to Certificateholders of such Trust of all amounts required to be distributed to them pursuant to the applicable Pass Through Trust Agreement and the disposition of all property held in such Trust. (Trust Supplement, Section 7.01) The applicable Trustee will send to each Certificateholder of such Trust notice of the termination of such Trust, the amount of the proposed final payment and the proposed date for the distribution of such final payment for such Trust. The final distribution to any Certificateholder of such Trust will be made only upon surrender of such Certificateholder's Certificates at the office or agency of the applicable Trustee specified in such notice of termination. (Section 11.01)

THE TRUSTEES

Wilmington Trust Company is the Trustee for each Trust.

BOOK-ENTRY; DELIVERY AND FORM

The New Certificates of each Trust will be represented by one or more permanent Global Certificates, in definitive, fully registered form without interest coupons, to be deposited with the Trustee as custodian for DTC and registered in the name of the nominee of DTC.

DTC has advised Atlas as follows: DTC is a limited purpose trust company organized under the laws of the State of New York, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Participants include securities brokers and dealers, banks, trust companies and clearing corporations and certain other organizations. Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly ("indirect participants").

Ownership of beneficial interests in the Global Certificates will be limited to persons who have accounts with DTC ("DTC Participants") or persons who hold interests through DTC Participants. Ownership of beneficial interests in the Global Certificates will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of DTC Participants) and the records of DTC Participants (with respect to interests of persons other than DTC Participants). The laws of some states require that certain purchasers of securities take

42

physical delivery of such securities. Such limits and such laws may limit the market for beneficial interests in the Global Certificates.

So long as DTC or its nominee is the registered owner or holder of the Global Certificates, DTC or such nominee, as the case may be, will be considered the sole record owner or holder of the New Certificates represented by such Global Certificates for all purposes under the related Pass Through Trust Agreements. No beneficial owners of an interest in the Global Certificates will be able to transfer that interest except in accordance with DTC's applicable procedures, in addition to those provided for under the Pass Through Trust Agreements, and, if applicable, the Euroclear System or Cedel Bank Societe Anonyme.

Payments of the principal of, premium, if any, and interest on the Global Certificates will be made to DTC or its nominee, as the case may be, as the registered owner thereof. Neither Atlas, the Trustee, nor any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Certificates or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Atlas expects that DTC or its nominee, upon receipt of any payment of principal, premium, if any, or interest in respect of the Global Certificates will credit DTC Participants' accounts with payments in amounts proportionate to their respective beneficial ownership interests in the principal amount of such Global Certificates, as shown on the records of DTC or its nominee. Atlas also expects that payments by DTC Participants to owners of beneficial interests in such Global Certificates held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such DTC Participants.

Neither Atlas nor the Trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

DEFINITIVE CERTIFICATES

Interests in Global Certificates of any class will be exchangeable or transferable, as the case may be, for certificates in definitive, fully registered form without interest coupons (the "Definitive Certificates") only if
(i) Atlas advises the Trustee in writing that DTC is no longer willing or able to discharge properly its responsibilities as depository with respect to such Certificates and Atlas is unable to locate a qualified successor within 90 days of receipt of such notice or, (ii) after the occurrence of certain events of default or other events specified in the Pass Through Trust Agreement, Certificateholders with fractional undivided interests aggregating not less than a majority in interest in such Trust advise the Trustee, Atlas and DTC through DTC Participants in writing that the continuation of a book-entry system through DTC (or a successor thereto) is no longer in the Certificateholders' best interests.

Upon the occurrence of any event described in the immediately preceding paragraph, the Trustee will be required to notify through participants all Certificateholders having a beneficial interest in the Global Certificates of the availability of Definitive Certificates. Upon surrender by DTC of the certificates representing the Global Certificates and receipt of instructions for re-registration, the Trustee will reissue the Certificates as Definitive Certificates to Certificateholders.

Distributions of principal, premium, if any, and interest with respect to Certificates will thereafter be made by the Trustee directly in accordance with the procedures set forth in the Pass Through Trust Agreement, to holders in whose names the Definitive Certificates were registered at the close of business on the applicable Record Date. Such distributions will be made by check mailed to the address of such holder as it appears on the register maintained by the Trustee. The final payment on any Certificate, however, will be made only upon presentation and surrender of such Certificate at the office or agency specified in the notice of final distribution to Certificateholders.

43

DESCRIPTION OF THE DEPOSIT AGREEMENTS

The following summary describes material terms of the deposit agreements ("Deposit Agreements"). The summary does not purport to be complete and is qualified in its entirety by reference to all of the provisions of the Deposit Agreements. The provisions of the Deposit Agreements are substantially identical except as otherwise indicated.

GENERAL

Under the Escrow Agreements, the Escrow Agent with respect to each Trust has entered into a separate Deposit Agreement with the Depositary. The Depositary has established separate accounts into which the proceeds of the original placement of the Old Certificates attributable to the applicable Trust were deposited (each, a "Deposit") on the Issuance Date on behalf of such Escrow Agent. Both Aircraft were delivered in April 2000 and the applicable amounts were withdrawn from the Deposits to finance the two Aircraft. On each Regular Distribution Date the Depositary will pay to the Paying Agent on behalf of the applicable Escrow Agent, for distribution to the holders of Escrow Receipts, an amount equal to interest accrued on the Deposit relating to such Trust during the relevant interest period at the rate per annum applicable to the Certificates issued by such Trust.

Upon each delivery of the Aircraft during the Delivery Period, the Trustee for each Trust requested the Escrow Agent relating to such Trust to withdraw from the Deposit relating to such Trust funds sufficient to enable the Trustee of such Trust to purchase the Equipment Note of the series applicable to such Trust issued with respect to such Aircraft. Accrued but unpaid interest on such Deposit (or portion thereof) withdrawn will be paid on the next Regular Distribution Date. The Deposit relating to each Trust and interest paid thereon will not be subject to the subordination provisions of the Intercreditor Agreement and will not be available to pay any amount due in respect of the Certificates.

DEPOSITARY

Westdeutsche Landesbank Girozentrale, New York Branch, is the depositary (the "Depositary"). WestLB, a German universal bank, provides commercial and investment banking services regionally, nationally and internationally to public, corporate and bank customers. WestLB is the largest of the German state banks. At December 31, 1998, WestLB had total assets of approximately DM 540.8 billion ($323.2 billion).

WestLB operates its New York Branch (the "Branch") pursuant to a license granted by the Superintendent of Banks of the State of New York in 1975. It is also subject to review and supervision by the Federal Reserve Bank. The Branch offers a range of financial products and advisory services.

WestLB has short-term unsecured debt ratings of P-1 from Moody's and A-1+ from Standard & Poor's.

WestLB's registered head office is located at Herzogstrasse 15, 40217 Dusseldorf, Germany, and its telephone number is 011-49-21-826-01. The Branch is located at 1211 Avenue of the Americas, New York, N.Y. 10036, and its telephone number is 212-852-6000. A copy of WestLB's 1998 Annual Report may be obtained from the Branch by delivery of a written request to the attention of the Branch Management.

The description of WestLB above has been provided by WestLB. WestLB, however, has not been involved in the preparation of, nor does it accept responsibility for, this prospectus.

Atlas shall have the option to substitute another financial institution acceptable to the Rating Agencies as Depositary under certain circumstances.

44

DESCRIPTION OF THE ESCROW AGREEMENTS

The following summary describes material terms of the escrow and paying agent agreements (the "Escrow Agreements"). The summary does not purport to be complete and is qualified in its entirety by reference to all of the provisions of the Escrow Agreements. The provisions of the Escrow Agreements are substantially identical except as otherwise indicated.

First Security Bank, National Association, as escrow agent in respect of each Trust (the "Escrow Agent"), Wilmington Trust Company, as paying agent on behalf of the Escrow Agent in respect of each Trust (the "Paying Agent"), each Trustee and the Initial Purchasers have entered into a separate Escrow Agreement for the benefit of the Certificateholders of each Trust as holders of the Escrow Receipts affixed thereto (in such capacity, a "Receiptholder"). The cash proceeds of the offering of Old Certificates of each Trust were deposited on behalf of the Escrow Agent (for the benefit of Receiptholders) with the Depositary as the Deposit relating to such Trust. Both Aircraft were delivered in April 2000 and the applicable amount of each Deposit was withdrawn from such Deposit to finance the Aircraft.

The Escrow Agent shall direct the Depositary to pay interest on the Deposits accrued in accordance with the Deposit Agreement to the Paying Agent for distribution to the Receiptholders. Each Escrow Agreement requires that the Paying Agent establish and maintain, for the benefit of the related Receiptholders, one or more Paying Agent Account(s), which shall be non-interest bearing. The Paying Agent shall deposit interest on Deposits in the related Paying Agent Account. The Paying Agent shall distribute these amounts on a Regular Distribution Date or Special Distribution Date, as appropriate.

The Escrow Agent has issued one or more escrow receipts (the "Escrow Receipts") which were affixed by the relevant Trustee to each Certificate. Each Escrow Receipt evidences a fractional undivided interest in amounts from time to time deposited into the Paying Agent Account and is limited in recourse to amounts deposited into such account. An Escrow Receipt may not be assigned or transferred except in connection with the assignment or transfer of the Certificate to which it is affixed. In connection with the Exchange Offer, each Escrow Receipt attached to an Old Certificate (an "Old Escrow Receipt") will be exchanged for an Escrow Receipt attached to a New Certificate (a "New Escrow Receipt") that will be identical in all material respects to the Old Escrow Receipt. Each Escrow Receipt will be registered by the Escrow Agent in the same name and manner as the Certificate to which it is affixed.

DESCRIPTION OF THE LIQUIDITY FACILITIES

The following summary describes material terms of the Liquidity Facilities and certain provisions of the Intercreditor Agreement relating to the Liquidity Facilities. The summary does not purport to be complete and is qualified in its entirety by reference to all of the provisions of the Liquidity Facilities and the Intercreditor Agreement. The provisions of the Liquidity Facilities are substantially identical except as otherwise indicated.

GENERAL

The liquidity provider for each trust (the "Liquidity Provider") has entered into a separate revolving credit agreement (each, a "Liquidity Facility") with the Subordination Agent. Under each Liquidity Facility, the Liquidity Provider will, if necessary, make one or more advances ("Interest Drawings") to the Subordination Agent in an aggregate amount (the "Required Amount") sufficient to pay interest on the Certificates on up to three consecutive semiannual Regular Distribution Dates at the respective interest rates shown on the cover page of this prospectus for such Certificates of the related Class (the "Stated Interest Rate"). If interest payment defaults occur which exceed the amount covered by or available under the Liquidity Facility for any Trust, the Certificateholders of such Trust will bear their allocable share of the deficiencies to the extent that there are no other sources of funds. Although WestLB, New York Branch, and MSCS are the initial Liquidity Providers, the Liquidity Provider for any Trust under certain circumstances may be replaced by one or more other entities. See "-- Replacement of Liquidity

45

Facilities." The obligations of MSCS to make advances under the Liquidity Facilities for the Class B Trust and the Class C Trust will be fully and unconditionally guaranteed by MSDW.

DRAWINGS

The initial amount available under the Liquidity Facilities for each Trust on the Issuance Date was as follows:

TRUST                                                  AVAILABLE AMOUNT
-----                                                  ----------------
Class A.............................................     $16,278,477
Class B.............................................     $ 6,078,289
Class C.............................................     $ 6,976,272

Except as otherwise provided below, the Liquidity Facility for each Trust will enable the Subordination Agent to make Interest Drawings thereunder on or promptly after any Regular Distribution Date to pay interest then due and payable on the Certificates of such Trust at the Stated Interest Rate for such Trust to the extent that the amount, if any, available to the Subordination Agent on such Regular Distribution Date is not sufficient to pay such interest; provided, however, that the maximum amount available to be drawn under a Liquidity Facility with respect to any Trust on any Regular Distribution Date to fund any shortfall of interest on Certificates of such Trust will not exceed the then Maximum Available Commitment under such Liquidity Facility.

The "Maximum Available Commitment" at any time under each Liquidity Facility is an amount equal to the then Required Amount of such Liquidity Facility less the aggregate amount of each Interest Drawing outstanding under such Liquidity Facility at such time, provided that following a Downgrade Drawing, a Final Drawing or a Non-Extension Drawing under a Liquidity Facility, the Maximum Available Commitment under such Liquidity Facility shall be zero.

The Liquidity Facility for any Class of Certificates does not provide for drawings thereunder to pay for principal of or premium on the Certificates of such Class or any interest on the Certificates of such Class in excess of the Stated Interest Rate for such Class or more than three semiannual installments of interest thereon or principal of or interest or premium on the Certificates of any other Class. (Liquidity Facilities, Section 2.02; Intercreditor Agreement, Section 3.6) In addition, the Liquidity Facility with respect to each Trust does not provide for drawings thereunder to pay any amounts payable with respect to the Deposits relating to such Trust.

Each payment by the Liquidity Provider reduces by the same amount the Maximum Available Commitment under the related Liquidity Facility, subject to reinstatement as hereinafter described. With respect to any Interest Drawings upon reimbursement of the Liquidity Provider in full for the amount of such Interest Drawings plus interest thereon, the Maximum Available Commitment under such Liquidity Facility in respect of interest on the Certificates of such Trust will be reinstated to an amount not to exceed the then Required Amount of such Liquidity Facility. However, such Liquidity Facility will not be so reinstated at any time if (i) a Liquidity Event of Default shall have occurred and be continuing and (ii) less than 65% of the then aggregate outstanding principal amount of all Equipment Notes are Performing Equipment Notes. With respect to any other drawings under such Liquidity Facility, amounts available to be drawn thereunder are not subject to reinstatement. The Required Amount of the Liquidity Facility for any Trust will be automatically reduced from time to time to an amount equal to the next three successive interest payments due on the Certificates of such Trust (without regard to expected future payment of principal of such Certificates) at the Stated Interest Rate for such Trust.
(Liquidity Facilities, Section 2.04(a); Intercreditor Agreement, Section 3.6(j))

"Performing Equipment Note" means an Equipment Note with respect to which no payment default has occurred and is continuing (without giving effect to any acceleration); provided that in the event of a bankruptcy proceeding involving Atlas under the U.S. Bankruptcy Code, (a) any payment default existing during the 60-day period under Section 1110(a)(1)(A) of the U.S. Bankruptcy Code (or such longer

46

period as may apply under Section 1110(b) of the U.S. Bankruptcy Code) (the "Section 1110 Period") shall not be taken into consideration, unless during the
Section 1110 Period the trustee in such proceeding or Atlas refuses to assume or agree to perform its obligations under the Lease related to such Equipment Note (in the case of a Leased Aircraft) or under the Owned Aircraft Indenture related to such Equipment Note (in the case of an Owned Aircraft), and (b) any payment default occurring after the date of the order of relief in such proceeding will not be taken into consideration if such payment default is cured under Section 1110(a)(1)(B) of the U.S. Bankruptcy Code before the later of 30 days after the date of such default or the expiration of the Section 1110 Period.

REPLACEMENT OF LIQUIDITY FACILITIES

If at any time (i) the short-term unsecured debt rating of any Liquidity Provider or, if applicable, of any guarantor of the obligations of a Liquidity Provider then issued by any of the Rating Agencies is lower than the Threshold Rating for the relevant Class or (ii) any guarantee of a Liquidity Provider's obligations under the relevant Liquidity Facilities becomes invalid or unenforceable, then the relevant Liquidity Facility may be replaced by a Replacement Facility. In the event that such Liquidity Facility is not replaced with a Replacement Facility, within 10 days after notice of the downgrading or such guarantee becoming invalid or unenforceable and as otherwise provided in the Intercreditor Agreement, such Liquidity Facility will be drawn in full up to the then Maximum Available Commitment under such Liquidity Facility (the "Downgrade Drawing") and the proceeds will be deposited into a cash collateral account (the "Cash Collateral Account") for such Class of Certificates and used for the same purposes and under the same circumstances and subject to the same conditions as cash payments of Interest Drawings under such Liquidity Facility would be used. (Liquidity Facilities, Section 2.02(c); Intercreditor Agreement,
Section 3.6(c))

A "Replacement Facility" for any Liquidity Facility means an irrevocable liquidity facility (or liquidity facilities) in substantially the form of the replaced Liquidity Facility, including reinstatement provisions, or in such other form (which may include a letter of credit) as shall permit the Rating Agencies to confirm in writing their respective ratings then in effect for the Certificates (before downgrading of such ratings, if any, as a result of the downgrading of the applicable Liquidity Provider), in a face amount (or in an aggregate face amount) equal to the applicable Required Amount and issued by a person having unsecured short-term debt ratings issued by the Rating Agencies which are equal to or higher than the Threshold Rating for the relevant Class. (Intercreditor Agreement, Section 1.1) The provider of any Replacement Facility will have the same rights (including, without limitation, priority distribution rights and rights as "Controlling Party") under the Intercreditor Agreement as the initial Liquidity Provider.

"Threshold Rating" means the short-term unsecured debt rating of P-1 by Moody's and A-1+ by Standard & Poor's, in the case of the Class A Liquidity Provider, and the short-term unsecured debt rating of P-1 by Moody's and A-1 by Standard & Poor's, in the case of the Class B and Class C Liquidity Provider.

The Liquidity Facility for each Trust provides that the Liquidity Provider's obligations thereunder will expire on the earliest of:

- January 26, 2001;

- the date on which the Subordination Agent delivers to such Liquidity Provider a certification that all of the Certificates of such Trust have been paid in full;

- the date on which the Subordination Agent delivers to such Liquidity Provider a certification that a Replacement Facility has been substituted for such Liquidity Facility;

47

- the fifth Business Day following receipt by the Subordination Agent of a Termination Notice from such Liquidity Provider (see "-- Liquidity Events of Default"); or

- the date on which no amount is or may (by reason of reinstatement) become available for drawing under such Liquidity Facility.

Each Liquidity Facility provides that the scheduled expiration date thereof may be extended for additional 364-day periods by mutual agreement of the relevant Liquidity Provider and the Subordination Agent. (Liquidity Facilities,
Section 2.10)

The Intercreditor Agreement provides for the replacement of the Liquidity Facility for any Trust if such Liquidity Facility is scheduled to expire earlier than 15 days after the Final Maturity Date for the Certificates of such Trust and such Liquidity Facility is not extended at least 25 days prior to its then scheduled expiration date. (Intercreditor Agreement, Section 3.6(d)) If such Liquidity Facility is not so extended or replaced by the 25th day prior to its then scheduled expiration date, such Liquidity Facility will be drawn in full up to the then Maximum Available Commitment under such Liquidity Facility (the "Non-Extension Drawing"). The proceeds of the Non-Extension Drawing will be deposited in the Cash Collateral Account for the related Class of Certificates as cash collateral to be used for the same purposes and under the same circumstances, and subject to the same conditions, as cash payments of Interest Drawings under such Liquidity Facility would be used. (Liquidity Facilities,
Section 2.02(b))

Subject to certain limitations, Atlas may, at its option, arrange for a Replacement Facility at any time to replace the liquidity facility for any Trust (including without limitation any Replacement Facility described in the following sentence). In addition, if any liquidity provider shall determine not to extend any liquidity facility, then such liquidity provider may, at its option, arrange for a Replacement Facility to replace such liquidity facility during the period no earlier than 40 days and no later than 25 days prior to the then scheduled expiration date of such liquidity facility. If any Replacement Facility is provided at any time after a Downgrade Drawing or a Non-Extension Drawing under any Liquidity Facility, the funds with respect to such liquidity facility on deposit in the Cash Collateral Account for such Trust will be returned to the liquidity provider being replaced. (Intercreditor Agreement,
Section 3.6(e))

Upon receipt by the Subordination Agent of a Termination Notice with respect to any Liquidity Facility from the relevant Liquidity Provider, the Subordination Agent shall request a final drawing (a "Final Drawing") under such Liquidity Facility in an amount equal to the then Maximum Available Commitment thereunder. The Subordination Agent will hold the proceeds of the Final Drawing in the Cash Collateral Account for the related Trust as cash collateral to be used for the same purposes and under the same circumstances, and subject to the same conditions, as cash payments of Interest Drawings under such Liquidity Facility would be used. (Liquidity Facilities, Section 2.02(d); Intercreditor Agreement, Section 3.6(i))

REIMBURSEMENT OF DRAWINGS

The Subordination Agent must reimburse amounts drawn under any Liquidity Facility by reason of an Interest Drawing, Final Drawing, Downgrade Drawing or Non-Extension Drawing and interest thereon, but only to the extent that the Subordination Agent has funds available therefor.

Interest Drawings and Final Drawings

Amounts drawn under any Liquidity Facility by reason of an Interest Drawing or the Final Drawing will be immediately due and payable, together with interest on the amount of such drawing. From the date of each such drawing to (but excluding) the third business day following the applicable Liquidity Provider's receipt of the notice of such drawing, interest will accrue at the Base Rate plus 2.25% per annum, in the case of the Class A Trust, and 2.00% per annum in the case of the Class B Trust or the Class C Trust. Thereafter, interest will accrue at LIBOR for the applicable Interest Period plus 2.25% per annum in the case of the Class A Trust and 2.00% per annum in the case of the Class B Trust or the Class C Trust. In the case of a Final Drawing, however, the Subordination Agent may convert the Final

48

Drawing into a drawing bearing interest at the Base Rate plus 2.25% per annum, in the case of the Class A Trust, and 2.00% per annum, in the case of the Class B Trust and the Class C Trust, on the last day of an Interest Period for such Drawing.

"Base Rate" means a fluctuating interest rate per annum in effect from time to time, which rate per annum shall at all times be equal to (a) the weighted average of the rates on overnight Federal funds transactions with members of the Federal Reserve System arranged by Federal funds brokers, as published for such day (or, if such day is not a business day, for the next preceding business day) by the Federal Reserve Bank of New York, or if such rate is not so published for any day that is a business day, the average of the quotations for such day for such transactions received by the Liquidity Provider from three Federal funds brokers of recognized standing selected by it, plus (b) one-quarter of one percent ( 1/4 of 1%).

"LIBOR" means, with respect to any interest period, (i) the rate per annum appearing on display page 3750 (British Bankers Association -- LIBOR) of the Dow Jones Markets Service (or any successor or substitute therefor) at approximately 11:00 A.M. (London time) two business days before the first day of such interest period, as the rate for dollar deposits with a maturity comparable to such interest period, or (ii) if the rate calculated pursuant to clause (i) above is not available, the average (rounded upwards, if necessary, to the next 1/16 of 1%) of the rates per annum at which deposits in dollars are offered for the relevant interest period by three banks of recognized standing selected by the applicable Liquidity Provider in the London interbank market at approximately 11:00 A.M. (London time) two business days before the first day of such interest period in an amount approximately equal to the principal amount of the LIBOR Advance to which such interest period is to apply and for a period comparable to such interest period.

Downgrade Drawings and Non-Extension Drawings

The amount drawn under any Liquidity Facility for any Trust by reason of a Downgrade Drawing or a Non-Extension Drawing will be treated as follows:

- such amount will be released on any Distribution Date to the relevant Liquidity Provider to the extent that such amount exceeds the Required Amount;

- any portion of such amount withdrawn from the Cash Collateral Account for such Certificate to pay interest on such Certificates will be treated in the same way as Interest Drawings; and

- the balance of such amount will be invested in Eligible Investments.

A Downgrade Drawing or a Non-Extension Drawing under the Liquidity Facility for the Class A Trust (other than any portion thereof applied to the payment of interest on the Class A Certificates) will bear interest equal to the earnings, if any, on funds on deposit in the Cash Collateral Account for the Class A Trust.

A Downgrade Drawing or a Non-Extension Drawing under the Liquidity Facility for the Class B Trust or the Class C Trust (other than any portion thereof applied to the payment of interest on the Certificates of Class B or Class C, respectively) will bear interest at (x) the greater of (A) an amount equal to the earnings, if any, plus 0.50% per annum on the outstanding amount from time to time of such Downgrade Drawing or Non-Extension Drawing for the Class B Trust or the Class C Trust, as applicable, for the relevant interest period and (B) interest on the outstanding amount from time to time of such Downgrade Drawing or Non-Extension Drawing, (i) at the Base Rate plus 0.50% per annum with respect to the period from the date of such drawing to (but excluding) the third business day following the applicable Liquidity Provider's receipt of the notice of such drawing, (ii) thereafter subject to clause (y) below, at a rate equal to LIBOR for the applicable interest period plus 0.50% per annum, and (y) from and after the date, if any, on which it is converted into a Final Drawing as described below under "-- Liquidity Events of Default," at a rate equal to LIBOR for the applicable Interest Period (or, as described in the fourth preceding paragraph, the Base Rate) plus 2.00% per annum. (Liquidity Facilities, Sections 2.06 and 3.07)

49

LIQUIDITY EVENTS OF DEFAULT

Events of Default under each Liquidity Facility (each, a "Liquidity Event of Default") will consist of:

- the acceleration of all the Equipment Notes; and

- certain bankruptcy or similar events involving Atlas. (Liquidity Facilities, Section 1.01)

If (i) any Liquidity Event of Default under any Liquidity Facility has occurred and is continuing and (ii) less than 65% of the aggregate outstanding principal amount of all Equipment Notes are Performing Equipment Notes, the applicable Liquidity Provider may, in its discretion, give a notice of termination of the related Liquidity Facility (a "Termination Notice"). The Termination Notice will have the following consequences:

- the related Liquidity Facility will expire on the fifth Business Day after the date on which such Termination Notice is received by the Subordination Agent;

- the Subordination Agent will promptly request, and the Liquidity Provider will make, a Final Drawing thereunder in an amount equal to the then Maximum Available Commitment thereunder;

- any Drawing remaining unreimbursed as of the date of termination will be automatically converted into a Final Drawing under such Liquidity Facility; and

- all amounts owing to the applicable Liquidity Provider will be automatically accelerated.

Notwithstanding the foregoing, the Subordination Agent will be obligated to pay amounts owing to the applicable Liquidity Provider only to the extent of funds available therefor after giving effect to the payments in accordance with the provisions set forth under "Description of the Intercreditor Agreement -- Priority of Distributions." (Liquidity Facilities, Section 6.01) Upon the circumstances described below under "Description of the Intercreditor Agreement -- Intercreditor Rights," a Liquidity Provider may become the Controlling Party with respect to the exercise of remedies under the Indentures.
(Intercreditor Agreement, Section 2.6(c))

INITIAL LIQUIDITY PROVIDERS

The initial Liquidity Provider for the Class A Trust is WestLB, acting through its New York Branch.

The initial Liquidity Provider for the Class B Trust and the Class C Trust is MSCS. MSCS, a subsidiary of MSDW, commenced operation in August 1985 and was established to conduct, primarily as principal, an interest rate, currency and equity derivatives products business. MSCS also engages in a variety of other related transactions.

MSDW, the guarantor of MSCS's obligations under its Liquidity Facilities, is a global financial services firm. MSDW has long-term unsecured debt ratings of Aa3 from Moody's and A+ from Standard & Poor's and short-term unsecured debt ratings of P-1 from Moody's and A-1 from Standard & Poor's. MSDW files reports, proxy statements and other information with the Commission pursuant to the information requirements of the Exchange Act. Such information can be inspected and copied at the public reference facilities of the Commission, or electronically accessed through the Internet.

The descriptions of MSCS and MSDW above have been provided by the respective parties. None of MSCS or MSDW, however, has been involved in the preparation of or accepts responsibility for this prospectus Morgan Stanley & Co. Incorporated, a subsidiary of MSDW and an affiliate of MSCS, acted as an Initial Purchaser of the Certificates.

DESCRIPTION OF THE INTERCREDITOR AGREEMENT

The following summary describes material provisions of the intercreditor agreement (the "Intercreditor Agreement") among the Trustees, the Liquidity Providers, Wilmington Trust Company, as subordination agent (the "Subordination Agent") and any holder of Class D Equipment Notes, if issued. The summary does not purport to be complete and is qualified in its entirety by reference to all of the provisions of the Intercreditor Agreement.

INTERCREDITOR RIGHTS

Controlling Party

Each Loan Trustee is directed in taking, or refraining from taking, any action thereunder or with respect to the Equipment Notes issued under the related Indenture, by the holders of at least a majority of the outstanding principal amount of the Equipment Notes issued under such Indenture, so long as no Indenture Event of Default (which, with respect to Leased Aircraft, has not been cured by the applicable Owner Trustee or Owner Participant) shall have occurred and be continuing thereunder. For so long as the Subordination Agent is the registered holder of the Equipment Notes, the Subordination Agent will act with respect to the preceding sentence in accordance with the directions of the Trustees for whom the Equipment Notes issued under such Indenture are held as Trust Property, to the extent constituting, in the aggregate, directions with respect to the required principal amount of Equipment Notes.

After the occurrence and during the continuance of an Indenture Event of Default under such Indenture (which, with respect to Leased Aircraft, has not been cured by the applicable Owner Trustee or Owner Participant), each Loan Trustee will be directed in taking, or refraining from taking, any action thereunder or with respect to the Equipment Notes issued under the related Indenture, including acceleration of such Equipment Notes or foreclosing the lien on the related Aircraft, by the Controlling Party, subject to the limitations described below. See "Description of the Certificates -- Indenture Event of Defaults and Certain Rights Upon an Indenture Event of Default" for a description of the rights of the Certificateholders of each Trust to direct the respective Trustees.

The "Controlling Party" will be:

- the Class A Trustee;

- upon payment of Final Distributions to the holders of Class A Certificates, the Class B Trustee; and

- upon payment of Final Distributions to the holders of Class B Certificates, the Class C Trustee.

At any time after 18 months from the earlier to occur of (x) the date on which the entire available amount under any Liquidity Facility shall have been drawn (for any reason other than a Downgrade Drawing or a Non-Extension Drawing) and remain unreimbursed, (y) the date on which the entire amount of any Downgrade Drawing or Non-Extension Drawing has been withdrawn from the relevant Cash Collateral Account to pay interest on the relevant Class of Certificates and remains unreimbursed and (z) the date on which all Equipment Notes shall have been accelerated, the Liquidity Provider with the greatest amount of unreimbursed Liquidity Obligations shall have the right to become the Controlling Party with respect to any Indenture.

For purposes of giving effect to the rights of the Controlling Party, the Trustees (other than the Controlling Party) shall irrevocably agree, and the Certificateholders (other than the Certificateholders represented by the Controlling Party) will be deemed to agree by virtue of their purchase of Certificates, that the Subordination Agent, as record holder of the Equipment Notes, shall exercise its voting rights in respect of the Equipment Notes as directed by the Controlling Party. (Intercreditor Agreement, Section 2.6) For a description of certain limitations on the Controlling Party's rights to exercise remedies, see "Description of the Equipment Notes -- Remedies."

51

"Final Distributions" means, with respect to the Certificates of any Trust on any Distribution Date, the sum of (x) the aggregate amount of all accrued and unpaid interest on such Certificates (excluding interest payable on the Deposit relating to such Trust) and (y) the Pool Balance of such Certificates as of the immediately preceding Distribution Date (less the amount of the Deposit for such Class of Certificates as of such preceding Distribution Date other than any portion of such Deposits thereafter used to acquire Equipment Notes pursuant to the Note Purchase Agreement). For purposes of calculating Final Distributions with respect to the Certificates of any Trust, any premium paid on the Equipment Notes held in such Trust which has not been distributed to the Certificateholders of such Trust (other than such premium or a portion thereof applied to the payment of interest on the Certificates of such Trust or the reduction of the Pool Balance of such Trust) shall be added to the amount of such Final Distributions.

Sale of Equipment Notes or Aircraft

Upon the occurrence and during the continuation of any Indenture Event of Default under any Indenture, the Controlling Party may accelerate and, subject to the provisions of the immediately following sentence, direct the Subordination Agent to sell all (but not less than all) of the Equipment Notes issued under such Indenture to any person. So long as any Certificates are outstanding, during nine months after the earlier of (x) the acceleration of the Equipment Notes under any Indenture and (y) the bankruptcy or insolvency of Atlas, without the consent of each Trustee, no Aircraft subject to the lien of such Indenture or such Equipment Notes may be sold, if the net proceeds from such sale would be less than the Minimum Sale Price for such Aircraft or such Equipment Notes. In addition, with respect to any Leased Aircraft, the amount and payment dates of rentals payable by Atlas under the related Lease for such Aircraft may not be adjusted during this nine-month period, if, as a result of such adjustment, the discounted present value of all such rentals would be less than 75% of the discounted present value of the rentals payable by Atlas under such Lease before giving effect to such adjustment. The discounted present value of all rentals shall be determined using the weighted average interest rate of the Equipment Notes outstanding under such Indenture as the discount rate.

"Minimum Sale Price" means, with respect to any Aircraft or the Equipment Notes issued in respect of such Aircraft, at any time, the lesser of (1) 75% of the Appraised Current Market Value of such Aircraft and (2) the aggregate outstanding principal amount of such Equipment Notes, plus accrued and unpaid interest thereon.

PRIORITY OF DISTRIBUTIONS

Before a Triggering Event

So long as no Triggering Event shall have occurred (whether or not continuing) all payments in respect of the Equipment Notes and certain other payments received on any Distribution Date will be promptly distributed by the Subordination Agent on such Distribution Date in the following order of priority:

- to the Liquidity Providers to the extent required to pay the Liquidity Expenses;

- to the Liquidity Providers to the extent required to pay interest accrued on the Liquidity Obligations;

- to the Liquidity Providers to the extent required to pay or reimburse the Liquidity Providers for the Liquidity Obligations (other than amounts payable pursuant to the two preceding clauses) and/or, if applicable, to replenish each Cash Collateral Account up to the applicable Required Amounts;

- to the Class A Trustee to the extent required to pay Expected Distributions on the Class A Certificates;

- to the Class B Trustee to the extent required to pay Expected Distributions on the Class B Certificates;

52

- to the Class C Trustee to the extent required to pay Expected Distributions on the Class C Certificates;

- if Class D Certificates have been issued, to the trustee for the Class D Trust (the "Class D Trustee") to the extent required to pay "Expected Distributions" (to be defined in a manner equivalent to the definition below for other Classes of Certificates) on the Class D Certificates; and

- to the Subordination Agent and each Trustee for the payment of certain fees and expenses.

"Liquidity Obligations" means the obligations to reimburse or to pay the Liquidity Providers all principal, interest, fees and other amounts owing to them under each Liquidity Facility or certain other agreements.

"Liquidity Expenses" means the Liquidity Obligations other than any interest accrued thereon or the principal amount of any drawing under the Liquidity Facilities.

"Expected Distributions" means, with respect to the Certificates of any Trust on any Distribution Date (the "Current Distribution Date"), the sum of (1) accrued and unpaid interest on such Certificates (excluding interest, if any, payable with respect to the Deposits relating to such Trust) and (2) the difference between:

(A) the Pool Balance of such Certificates as of the immediately preceding Distribution Date (or, if the Current Distribution Date is the first Distribution Date, the original aggregate face amount of the Certificates of such Trust); and

(B) the Pool Balance of such Certificates as of the Current Distribution Date calculated on the basis that (i) the principal of the Equipment Notes held in such Trust has been paid when due (whether at stated maturity, upon redemption, prepayment, purchase or acceleration or otherwise) and such payments have been distributed to the holders of such Certificates and (ii) the principal of any Equipment Notes formerly held in such Trust that have been sold pursuant to the Intercreditor Agreement has been paid in full and such payments have been distributed to the holders of such Certificates, but without giving effect to any reduction in the Pool Balance as a result of any distribution attributable to the Deposit occurring after the immediately preceding Distribution Date (or, if the Current Distribution Date is the first Distribution Date, occurring after the initial issuance of the Certificates of such Trust).

For purposes of determining the priority of distributions on account of the redemption, purchase or prepayment of all of the Equipment Notes issued pursuant to an Indenture, clause (1) of the definition of Expected Distributions shall be deemed to read as follows: "(1) accrued, due and unpaid interest on such Certificates (excluding interest, if any, payable with respect to the Deposits relating to such Trust) together with (without duplication) accrued and unpaid interest on a portion of such Certificates equal to the outstanding principal amount of the Equipment Notes being redeemed, purchased or prepaid (immediately prior to such redemption, purchase or prepayment)."

After a Triggering Event

Subject to the terms of the Intercreditor Agreement, upon the occurrence of a Triggering Event and at all times thereafter, all funds received by the Subordination Agent in respect of the Equipment Notes and certain other payments will be promptly distributed by the Subordination Agent in the following order of priority:

- to the Subordination Agent, any Trustee, any Certificateholder and the Liquidity Providers to the extent required to pay certain out-of-pocket costs and expenses actually incurred by the Subordination Agent or any Trustee or to reimburse any Certificateholder or the Liquidity Providers in respect of payments made to the Subordination Agent or any Trustee in connection with the protection or realization of the value of the Equipment Notes, any Trust Indenture Estate under

53

(and as defined in) any Leased Aircraft Indenture or Collateral under (and as defined in) any Owned Aircraft Indenture (collectively, the "Administration Expenses");

- to the Liquidity Providers to the extent required to pay the Liquidity Expenses;

- to the Liquidity Providers to the extent required to pay interest accrued on the Liquidity Obligations;

- to the Liquidity Providers to the extent required to pay the outstanding amount of all Liquidity Obligations and/or, if applicable, with respect to any particular Liquidity Facility, unless (x) less than 65% of the aggregate outstanding principal amount of all Equipment Notes are Performing Equipment Notes and a Liquidity Event of Default shall have occurred and is continuing under such Liquidity Facility or (y) a Final Drawing shall have occurred under such Liquidity Facility, to replenish the Cash Collateral Account with respect to such Liquidity Facility up to the Required Amount for the related Class of Certificates (less the amount of any repayments of Interest Drawings under such Liquidity Facility while sub-clause (x) of this clause is applicable);

- to the Subordination Agent, any Trustee or any Certificateholder to the extent required to pay certain fees, taxes, charges and other amounts payable;

- to the Class A Trustee to the extent required to pay Adjusted Expected Distributions on the Class A Certificates.

- to the Class B Trustee to the extent required to pay Adjusted Expected Distributions on the Class B Certificates;

- to the Class C Trustee to the extent required to pay Adjusted Expected Distributions on the Class C Certificates; and

- if Class D Certificates have been issued, to the Class D Trustee to the extent required to pay "Adjusted Expected Distributions" (to be defined in a manner equivalent to the definition below for other Classes of Certificates) on the Class D Certificates.

"Adjusted Expected Distributions" means, with respect to the Certificates of any Trust on any Current Distribution Date, the sum of (1) accrued and unpaid interest on such Certificates (excluding interest, if any, payable with respect to the Deposits relating to such Trust) and (2) the greater of:

(A) the difference between (x) the Pool Balance of such Certificates as of the immediately preceding Distribution Date (or, if the Current Distribution Date is the first Distribution Date, the original aggregate face amount of the Certificates of such Trust) and (y) the Pool Balance of such Certificates as of the Current Distribution Date calculated on the basis that (i) the principal of the Equipment Notes other than Performing Equipment Notes (the "Non-Performing Equipment Notes") held in such Trust has been paid in full and such payments have been distributed to the holders of such Certificates, (ii) the principal of the Performing Equipment Notes held in such Trust has been paid when due (but without giving effect to any acceleration of Performing Equipment Notes) and such payments have been distributed to the holders of such Certificates and
(iii) the principal of any Equipment Notes formerly held in such Trust that have been sold pursuant to the Intercreditor Agreement has been paid in full and such payments have been distributed to the holders of such Certificates, but without giving effect to any reduction in the Pool Balance as a result of any distribution attributable to the Deposit occurring after the immediately preceding Distribution Date (or, if the Current Distribution Date is the first Distribution Date, occurring after the initial issuance of the Certificates of such Trust), and

(B) the amount of the excess, if any, of (i) the Pool Balance of such Class of Certificates as of the immediately preceding Distribution Date (or, if the Current Distribution Date is the first Distribution Date, the original aggregate face amount of the Certificates of such Trust), less the amount of the Deposits for such Class of Certificates as of such preceding Distribution Date (or, if the Current Distribution Date is the first Distribution Date, the original aggregate amount of the

54

Deposit for such Class of Certificates) other than any portion of such Deposit thereafter used to acquire Equipment Notes pursuant to the Note Purchase Agreement (the amount described in this clause (i), the "Current Pool Balance"), over (ii) the Aggregate LTV Collateral Amount for such Class of Certificates for the Current Distribution Date;

provided that, until the date of the initial LTV Appraisals, clause (B) shall not apply.

For purposes of calculating Expected Distributions or Adjusted Expected Distributions with respect to the Certificates of any Trust, any premium paid on the Equipment Notes held in such Trust that has not been distributed to the Certificateholders of such Trust (other than such premium or a portion thereof applied to the payment of interest on the Certificates of such Trust or the reduction of the Pool Balance of such Trust) shall be added to the amount of Expected Distributions or Adjusted Expected Distributions.

"Aggregate LTV Collateral Amount" for any Class of Certificates for any Distribution Date means the product of (i) the sum of the applicable LTV Collateral Amounts for each Aircraft, minus (ii) the Pool Balance for each Class of Certificates, if any, senior to such Class, after giving effect to any distribution of principal on such Distribution Date with respect to such senior Class or Classes.

"LTV Collateral Amount" of any Aircraft for any Class of Certificates means, as of any Distribution Date, the lesser of (i) the LTV Ratio for such Class of Certificates multiplied by the Appraised Current Market Value of such Aircraft (or with respect to any such Aircraft which has suffered an Event of Loss under and as defined in the relevant Lease, in the case of a Leased Aircraft, or relevant Indenture, in the case of an Owned Aircraft, the amount of the insurance proceeds paid to the related Loan Trustee in respect thereof to the extent then held by such Loan Trustee (and/or on deposit in the Special Payments Account) or payable to such Loan Trustee in respect thereof) and (ii) the outstanding principal amount of the Equipment Notes secured by such Aircraft after giving effect to any principal payments of such Equipment Notes on or before such Distribution Date.

"LTV Ratio" means for the Class A Certificates 39.0%, for the Class B Certificates 53.0% and for the Class C Certificates 68.0%.

"Appraised Current Market Value" of any Aircraft means the lower of the average and the median of the most recent three LTV Appraisals of such Aircraft.

After a Triggering Event occurs and any Equipment Note becomes a Non-Performing Equipment Note, the Subordination Agent shall obtain LTV Appraisals of the Aircraft securing such Equipment Note as soon as practicable and additional LTV Appraisals on or prior to each anniversary of the date of such initial LTV Appraisals; provided that if the Controlling Party reasonably objects to the appraised value of the Aircraft shown in such LTV Appraisals, the Controlling Party shall have the right to obtain or cause to be obtained substitute LTV Appraisals (including LTV Appraisals based upon physical inspection of such Aircraft).

"LTV Appraisal" means a current fair market value appraisal (which may be a "desk-top" appraisal) performed by any Appraiser or any other nationally recognized appraiser on the basis of an arm's-length transaction between an informed and willing purchaser under no compulsion to buy and an informed and willing seller under no compulsion to sell and both having knowledge of all relevant facts.

Interest Drawings under the Liquidity Facility and withdrawals from the Cash Collateral Account, in each case in respect of interest on the Certificates of any Trust, will be distributed to the Trustee for such Trust, notwithstanding the priority of distributions set forth in the Intercreditor Agreement and otherwise described herein.

ADDITION OF TRUSTEE FOR CLASS D CERTIFICATES

If the Class D Certificates are issued, the Class D Trustee will become a party to the Intercreditor Agreement.

Any resignation or removal of the Subordination Agent and appointment of a successor Subordination Agent does not become effective until acceptance of the appointment by the successor Subordination Agent. (Intercreditor Agreement,
Section 8.1)

DESCRIPTION OF THE AIRCRAFT AND THE APPRAISALS

THE AIRCRAFT

The Aircraft consist of two new Boeing 747-400F aircraft, both of which were delivered by the manufacturer to Atlas in April 2000. The Aircraft have been designed to be in compliance with Stage 3 noise level standards. The Boeing 747-400F aircraft is a long-range aircraft with payload capacity of approximately 150 tons. The engine type expected to be utilized on each Aircraft is the General Electric Model CF6-80C2B5FG04.

THE APPRAISALS

The table below sets forth the appraised base values as determined by AvSolutions, Inc. ("AvS"), Morton Beyer and Agnew, Inc. ("MBA") and Simat Helliesen & Eichner, Inc. ("SH&E"), independent aircraft appraisal and consulting firms (the "Appraisers") and certain additional information regarding the Aircraft.

(1) The actual delivery month for each Aircraft was April 2000.

For purposes of the foregoing chart, each Appraiser was asked to provide its opinion as to the appraised base value of each Aircraft projected as of the scheduled delivery month of each such Aircraft. As part of this process, all three Appraisers performed "desk-top" appraisals without any physical inspection of the Aircraft. The appraisals are based on various assumptions and methodologies, which vary among the appraisals. The Appraisers have delivered letters summarizing their respective appraisals, copies of which are annexed to this prospectus as Appendix B. For a definition of appraised base value and a discussion of the assumptions and methodologies used in each of the appraisals, reference is hereby made to such letters.

An appraisal is only an estimate of value. It is not indicative of the price at which an aircraft may be purchased from the manufacturer and should not be relied upon as a measure of realizable value. The proceeds realized upon a sale of any Aircraft may be less than its appraised base value. The value of the Aircraft in the event of the exercise of remedies under the applicable Indenture will depend on market and economic conditions, the availability of buyers, the condition of the Aircraft and other similar factors. Accordingly, there can be no assurance that the proceeds realized upon any such exercise with respect to

56

the Equipment Notes and the Aircraft pursuant to the applicable Indenture would equal the appraised value of such Aircraft or be sufficient to satisfy in full payments due on the Equipment Notes issued thereunder or the Certificates.

DELIVERIES OF AIRCRAFT

The Note Purchase Agreement provides that the delivery period (the "Delivery Period") will expire on December 31, 2000, subject to extension if a labor strike occurs at Boeing prior to December 31, 2000, by the number of days that such strike continues in effect (the "Delivery Period Termination Date").

DESCRIPTION OF THE EQUIPMENT NOTES

The statements under this caption describe certain terms of the Equipment Notes, the Indentures, the Leases, the Participation Agreements, the trust agreements under which the Owner Trustees act on behalf of the Owner Participants (the "Trust Agreements") and the Note Purchase Agreement and do not purport to be complete. The summaries make use of terms defined in and are qualified in their entirety by reference to all of the provisions of the Equipment Notes, the Indentures, the Leases, the Participation Agreements, the Trust Agreements and the Note Purchase Agreement, forms of which were filed as exhibits to the Registration Statement and copies of which are available as set forth under the heading "Where You Can Find More Information." Except as otherwise indicated, the following summaries relate to the Equipment Notes, the Indenture, the Lease, the Participation Agreement and the Trust Agreement that may be applicable to each Aircraft.

Under the Note Purchase Agreement, Atlas has the option of entering into a leveraged lease financing or a secured debt financing with respect to each of the Aircraft.

- If Atlas chooses to enter into a leveraged lease financing with respect to an Aircraft, the Note Purchase Agreement provides for the relevant parties to enter into a Participation Agreement, a Lease and a Leased Aircraft Indenture (among other documents) relating to the financing of such Leased Aircraft.

- If Atlas chooses to enter into a secured debt financing with respect to an Aircraft, the Note Purchase Agreement provides for the relevant parties to enter into a Participation Agreement and an Owned Aircraft Indenture relating to the financing of such Owned Aircraft.

The description of such agreements in this prospectus is based on the forms of such agreements annexed to the Note Purchase Agreement. In the case of Leased Aircraft, the terms of the agreements actually entered into may differ from the forms of such agreements and, consequently, may differ from the description of such agreements contained in this prospectus. This is because a third party -- the owner participant that will be the beneficial owner of the Leased Aircraft (the "Owner Participant") -- will provide a portion of the financing of such Aircraft and may request changes. However, under the Note Purchase Agreement, the terms of such agreements are required to (i) contain the Mandatory Documents Terms and (ii) not vary the Mandatory Economic Terms. In addition, Atlas will be obligated (i) to certify to the Trustees that any such modifications do not materially and adversely affect the Certificateholders and
(ii) to obtain written confirmation from each Rating Agency that the use of versions of such agreements modified in any material respect would not result in a withdrawal, suspension or downgrading of the ratings of any Class of Certificates. See "Description of the Certificates -- Obligation to Purchase Equipment Notes." Each Owner Participant will be required to satisfy certain requirements, including having a minimum combined capital and surplus or net worth.

GENERAL

The Equipment Notes will be issued in up to three series with respect to each Aircraft (the "Series A Equipment Notes," the "Series B Equipment Notes," the "Series C Equipment Notes," and, collectively, the "Equipment Notes"). Atlas may elect to issue an additional series with respect to Owned Aircraft (the

57

"Series D Equipment Notes"), which will be funded from sources other than the original placement of the Old Certificates. See "Description of the Certificates -- Possible Issuance of Series D Equipment Notes." The Equipment Notes with respect to each Leased Aircraft will be issued under a separate Leased Aircraft Indenture between First Security Bank, National Association, as owner trustee of a trust for the benefit of the Owner Participant who will be the beneficial owner of such Aircraft (each, an "Owner Trustee"), and Wilmington Trust Company, as an indenture trustee thereunder (each, a "Leased Aircraft Trustee"). The Equipment Notes with respect to each Owned Aircraft will be issued under a separate Owned Aircraft Indenture between Atlas and Wilmington Trust Company, as indenture trustee thereunder (each, an "Owned Aircraft Trustee" and, together with the other Owned Aircraft Trustees and the Leased Aircraft Trustees, the "Loan Trustees"). The Indentures will not provide for defeasance, or discharge upon deposit of cash or certain obligations of the United States.

The related Owner Trustee will lease each Leased Aircraft to Atlas pursuant to a separate Lease between such Owner Trustee and Atlas with respect to such Leased Aircraft. Under each Lease, Atlas will be obligated to make or cause to be made rental and other payments to the related Leased Aircraft Trustee on behalf of the related Owner Trustee, which rental and other payments will be at least sufficient to pay in full when due all payments required to be made on the Equipment Notes issued with respect to such Leased Aircraft. The Equipment Notes issued with respect to the Leased Aircraft are not, however, direct obligations of, or guaranteed by, Atlas. Atlas' rental obligations under each Lease and Atlas' obligations under the Equipment Notes issued with respect to each Owned Aircraft will be general obligations of Atlas.

SUBORDINATION

The Indenture provides for the following subordination provisions applicable to the Equipment Notes:

- Series A Equipment Notes issued in respect of an Aircraft will rank senior in right of payment to other Equipment Notes issued in respect of such Aircraft;

- Series B Equipment Notes issued in respect of an Aircraft will rank junior in right of payment to the Series A Equipment Notes issued in respect of such Aircraft and will rank senior to the Series C and, if applicable, Series D Equipment Notes issued in respect of such Aircraft;

- Series C Equipment Notes issued in respect of such Aircraft will rank junior in right of payment to the Series A and Series B Equipment Notes issued in respect of such Aircraft and, if Series D Equipment Notes are issued with respect to such Aircraft, senior to such Series D Equipment Notes; and

- If Atlas elects to issue Series D Equipment Notes with respect to an Aircraft, they will be subordinated in right of payment to the Series A, Series B, and Series C Equipment Notes issued with respect to such Aircraft.

PRINCIPAL AND INTEREST PAYMENTS

Subject to the provisions of the Intercreditor Agreement, interest paid on the Equipment Notes held in each Trust will be passed through to the Certificateholders of such Trust on the dates and at the rate per annum set forth on the cover page of this prospectus with respect to Certificates issued by such Trust until the final expected Regular Distribution Date for such Trust. Subject to the provisions of the Intercreditor Agreement, principal paid on the Equipment Notes held in each Trust will be passed through to the Certificateholders of such Trust in scheduled amounts on the dates set forth herein until the final expected Regular Distribution Date for such Trust.

Interest will be payable on the unpaid principal amount of each Equipment Note at the rate applicable to such Equipment Note on January 2 and July 2 of each year, commencing on July 2, 2000. Such interest will be computed on the basis of a 360-day year of twelve 30-day months.

58

Scheduled principal payments on the Equipment Notes will be made on January 2 and July 2 in certain years, commencing on, January 2, 2001 (or, in the case of Equipment Notes issued after such date, commencing with the first such date to occur after initial issuance thereof). See "Description of the Certificates -- Pool Factors" for a discussion of the scheduled payments of principal of the Equipment Notes and possible revisions thereto.

If any date scheduled for a payment of principal, premium (if any) or interest with respect to the Equipment Notes is not a Business Day, such payment will be made on the next succeeding Business Day without any additional interest.

REDEMPTION

If an Event of Loss occurs with respect to an Aircraft and such Aircraft is not replaced by Atlas under the related Lease (in the case of a Leased Aircraft) or under the related Owned Aircraft Indenture (in the case of an Owned Aircraft), the Equipment Notes issued with respect to such Aircraft will be redeemed, in whole, in each case at a price equal to the aggregate unpaid principal amount thereof, together with accrued interest thereon to, but not including, the date of redemption, but without premium, on a Special Distribution Date. (Leased Aircraft Indentures, Section 2.10(a)) (Owned Aircraft Indentures, Section 2.10)

If Atlas exercises its right to terminate a Lease under Section 9 or
Section 17.3.1 of such Lease, the Equipment Notes relating to the applicable Leased Aircraft will be redeemed, in whole, on a Special Distribution Date at a price equal to the aggregate unpaid principal amount thereof, together with accrued and unpaid interest thereon to, but not including, the date of redemption, plus a Make-Whole Premium, if any. (Leased Aircraft Indentures,
Section 2.10(b)) See "-- The Leases and Certain Provisions of the Owned Aircraft Indentures -- Lease Termination."

All (but not less than all) of the Equipment Notes issued with respect to a Leased Aircraft may be redeemed prior to maturity at the option of the issuer with the prior written consent of Atlas and all of the Equipment Notes issued with respect to an Owned Aircraft may be redeemed prior to maturity at the option of Atlas, in each case at a price equal to the aggregate unpaid principal thereof, together with accrued interest thereon to, but not including, the date of redemption, plus a Make-Whole Premium, if any. (Indentures, Section 2.11)

Notice of redemption shall be given to each Note Holder by the Loan Trustee not less than 15 nor more than 60 days prior to the applicable redemption date. If notice of such a redemption shall have been given (A) in connection with a refinancing of Equipment Notes with respect to an Aircraft, such notice may be revoked not later than three days prior to the proposed redemption date and (B) in connection with the anticipated termination of a Lease as described above, such notice may be revoked, and shall be deemed revoked, in the event the Lease does not in fact terminate. In addition, the redemption date may be postponed for up to 10 Business Days. (Indentures, Section 2.12)

If, with respect to a Leased Aircraft, (x) one or more Lease Events of Default shall have occurred and are continuing, (y) in the event of a bankruptcy proceeding involving Atlas, (i) during the Section 1110 Period, the trustee in such proceeding or Atlas does not assume or agree to perform its obligations under the related Lease or (ii) at any time after assuming or agreeing to perform such obligations, such trustee or Atlas ceases to perform such obligations such that the stay period applicable under the U.S. Bankruptcy Code comes to an end or (z) the Equipment Notes with respect to such Leased Aircraft have been accelerated or the Leased Aircraft Trustee with respect to such Equipment Notes takes action or notifies the applicable Owner Trustee that it intends to take action to foreclose the lien of the related Leased Aircraft Indenture or otherwise commence the exercise of any significant remedy under such Indenture or the related Lease, then in each case all, but not less than all, of the Equipment Notes issued with respect to such Leased Aircraft may be purchased by the related Owner Trustee or Owner Participant on the applicable purchase date at a price equal to the aggregate unpaid principal thereof, together with accrued and unpaid interest thereon to, but not including, the date of purchase, but without any premium (provided that a Make-Whole Premium shall be payable if such

59

Equipment Notes are to be purchased pursuant to clause (x) when a Lease Event of Default shall have occurred and been continuing for less than 180 days). (Leased Aircraft Indentures, Section 2.13) Atlas as owner of the Owned Aircraft has no comparable right under the Owned Aircraft Indentures to purchase Equipment Notes under such circumstances.

"Make-Whole Premium" means, with respect to any Equipment Note, an amount (as determined by an independent investment bank of national standing) equal to the excess, if any, of (a) the present value of the remaining scheduled payments of principal and interest to maturity of such Equipment Note computed by discounting such payments on a semiannual basis on each payment date under the applicable Indenture (assuming a 360-day year of twelve 30-day months) using a discount rate equal to the Treasury Yield over (b) the outstanding principal amount of such Equipment Note plus accrued interest to the date of determination.

For purposes of determining the Make-Whole Premium, "Treasury Yield" means, at the date of determination with respect to any Equipment Note, the interest rate (expressed as a decimal and, in the case of United States Treasury bills, converted to a bond equivalent yield) determined to be the per annum rate equal to the semiannual yield to maturity for United States Treasury securities maturing on the Average Life Date of such Equipment Note and trading in the public securities markets either as determined by interpolation between the most recent weekly average yield to maturity for two series of United States Treasury securities trading in the public securities markets, (A) one maturing as close as possible to, but earlier than, the Average Life Date of such Equipment Note and (B) the other maturing as close as possible to, but later than, the Average Life Date of such Equipment Note, in each case as published in the most recent H.15(519) or, if a weekly average yield to maturity for United States Treasury securities maturing on the Average Life Date of such Equipment Note is reported in the most recent H.15(519), such weekly average yield to maturity as published in such H.15(519). "H.15(519)" means the weekly statistical release designated as such, or any successor publication, published by the Board of Governors of the Federal Reserve System. The date of determination of a Make-Whole Premium shall be the third Business Day prior to the applicable payment or redemption date and the "most recent H.15(519)" means the H.15(519) published prior to the close of business on the third Business Day prior to the applicable payment or redemption date.

"Average Life Date" for any Equipment Note shall be the date which follows the time of determination by a period equal to the Remaining Weighted Average Life of such Equipment Note. "Remaining Weighted Average Life" on a given date with respect to any Equipment Note shall be the number of days equal to the quotient obtained by dividing (a) the sum of each of the products obtained by multiplying (i) the amount of each then remaining scheduled payment of principal of such Equipment Note by (ii) the number of days from and including such determination date to but excluding the date on which such payment of principal is scheduled to be made, by (b) the then outstanding principal amount of such Equipment Note.

SECURITY

Leased Aircraft

The Equipment Notes issued with respect to each Leased Aircraft will be secured by:

- an assignment by the related Owner Trustee to the related Leased Aircraft Trustee of such Owner Trustee's rights, except for certain rights, under the Lease with respect to the related Leased Aircraft, including the right to receive payments of rent thereunder;

- a mortgage to such Leased Aircraft Trustee of such Aircraft, subject to the rights of Atlas under such Lease; and

- an assignment to such Leased Aircraft Trustee of certain of such Owner Trustee's rights under the purchase agreement between Atlas and the Leased Aircraft manufacturer.

60

Unless and until an Indenture Event of Default with respect to a Leased Aircraft has occurred and is continuing, the Leased Aircraft Trustee may not exercise the rights of the Owner Trustee under the related Lease, except the Owner Trustee's right to receive payments of rent due thereunder. The assignment by the Owner Trustee to the Leased Aircraft Trustee of its rights under the related Lease will exclude certain rights of such Owner Trustee and the related Owner Participant, including the rights of the Owner Trustee and the Owner Participant with respect to indemnification by Atlas for certain matters, insurance proceeds payable to such Owner Trustee in its individual capacity or to such Owner Participant under public liability insurance maintained by Atlas under such Lease or by such Owner Trustee or such Owner Participant, insurance proceeds payable to such Owner Trustee in its individual capacity or to such Owner Participant under certain casualty insurance maintained by such Owner Trustee or such Owner Participant under such Lease and certain reimbursement payments made by Atlas to such Owner Trustee. (Leased Aircraft Indenture, Granting Clause) The Equipment Notes issued in respect of any one Aircraft will not be secured by any of the other Aircraft or Leases (except in certain cases, if any, where the related Owner Participant and Atlas shall agree to cross-collateralization). Accordingly, any excess proceeds from the exercise of remedies with respect to the Equipment Notes relating to an Aircraft will not be available to cover any shortfall with respect to any other Aircraft.

Owned Aircraft

The Equipment Notes issued with respect to each Owned Aircraft will be secured by:

- a mortgage to the Owned Aircraft Trustee of such Aircraft; and

- an assignment to the Owned Aircraft Trustee of certain of Atlas' rights under its purchase agreement with the Aircraft manufacturer.

Cash

Cash, if any, held from time to time by the Loan Trustee with respect to any Aircraft, including funds held as the result of an Event of Loss to such Aircraft or, in the case of a Leased Aircraft, termination of the Lease, if any, relating thereto, will be invested and reinvested by such Loan Trustee, at the direction of the related Owner Trustee in the case of the Leased Aircraft or Atlas in the case of the Owned Aircraft, in investments described in the related Indenture. (Leased Aircraft Indentures, Section 5.09; Owned Aircraft Indentures,
Section 6.06)

LOAN TO VALUE RATIOS OF EQUIPMENT NOTES

The following table sets forth illustrative loan to Aircraft value ratios for the Equipment Notes issued in respect of a Leased Aircraft as of each January 2 Regular Distribution Date occurring after the scheduled date of original issuance of such Equipment Notes, assuming that Series A, Series B, and Series C Equipment Notes in the maximum principal amount are issued in respect of such Aircraft. This example was utilized by Atlas in preparing the Assumed Amortization Schedule, although the amortization schedule for the Series A, Series B and Series C Equipment Notes issued with respect to an Aircraft may vary from such assumed schedule so long as it complies with the Mandatory Economic Terms. Accordingly, the schedule set forth below may not be applicable in the case of any particular Leased Aircraft or in the case of any Owned Aircraft. See "Description of the Certificates -- Pool Factors." The LTV was obtained by dividing (i) the outstanding balance (assuming no payment default) of such Equipment Notes determined immediately after giving effect to the payments scheduled to be made on each such Regular Distribution Date by (ii) the assumed value (the "Assumed Aircraft Value") of the Aircraft securing such Equipment Notes.

The following table is based on the assumption (the "Depreciation Assumption") that the value of the Aircraft set forth opposite the initial Regular Distribution Date included in the table depreciates by 3% of the initial appraised value per year for the first 20 years after the year of delivery of such Aircraft and by 4% of the initial appraised value per year thereafter. Other rates or methods of depreciation would result in materially different loan to Aircraft value ratios, and no assurance can be given (i) that the

61

depreciation rates and method assumed for the purposes of the table are the ones most likely to occur or (ii) as to the actual future value of any Aircraft. Thus the table should not be considered a forecast or prediction of expected or likely loan to Aircraft value ratios, but simply a mathematical calculation based on one set of assumptions.

LIMITATION OF LIABILITY

The Equipment Notes issued with respect to each Leased Aircraft are not direct obligations of, or guaranteed by, Atlas, any Owner Participant or the Leased Aircraft Trustees or the Owner Trustees in their individual capacities. None of the Owner Trustees, the Owner Participants or the Leased Aircraft Trustees, or any affiliates thereof, will be personally liable to any holder of an Equipment Note or, in the case of the Owner Trustees and the Owner Participants, to the Leased Aircraft Trustees for any amounts payable under the Equipment Notes or, except as provided in each Leased Aircraft Indenture, for any liability under such Leased Aircraft Indenture. All payments of principal of, premium, if any, and interest on the Equipment Notes issued with respect to any Leased Aircraft (other than payments made in connection with an optional redemption or purchase of Equipment Notes issued with respect to a Leased Aircraft by the related Owner Trustee or the related Owner Participant) will be made only from the assets subject to the lien of the Indenture with respect to such Leased Aircraft or the income and proceeds received by the related Leased Aircraft Trustee therefrom (including rent payable by Atlas under the Lease with respect to such Leased Aircraft).

The Equipment Notes issued with respect to the Owned Aircraft will be direct obligations of Atlas.

Except as otherwise provided in the Indentures, each Owner Trustee and each Loan Trustee, in its individual capacity, will not be answerable or accountable under the Indentures or under the Equipment Notes under any circumstances except, among other things, for its own willful misconduct or gross negligence. None of the Owner Participants will have any duty or responsibility under any of the Leased Aircraft Indentures or the Equipment Notes to the Leased Aircraft Trustees or to any holder of any Equipment Note. (Owned Aircraft Indenture,
Section 7.01; Leased Aircraft Indenture, Section 6.01)

INDENTURE DEFAULTS, NOTICE AND WAIVER

Indenture Events of Default under each Indenture will include:

- in the case of a Leased Aircraft Indenture, the occurrence of any Lease Event of Default under the related Lease (other than the failure to make certain indemnity payments and other payments to the related Owner Trustee or Owner Participant unless a notice is given by such Owner Participant that such failure shall constitute an Indenture Default);

- the failure by the related Owner Trustee (other than as a result of a Lease Default or Lease Event of Default), in the case of a Leased Aircraft Indenture, or Atlas, in the case of an Owned Aircraft Indenture, to pay any interest or principal or premium, if any, under such Indenture or under any Equipment Note issued thereunder that continues for more than 10 Business Days, in the case of principal, interest or Make-Whole Premium, and, in all other cases, 10 Business Days after the relevant Owner Trustee or Owner Participant, in the case of a Leased Aircraft Indenture or Atlas, in the case of an Owned Aircraft Indenture, receives written demand from the related Loan Trustee or holder of an Equipment Note;

- the failure by the related Owner Participant or the related Owner Trustee (in its individual capacity), in the case of a Leased Aircraft Indenture, to discharge certain liens that continue after notice and specified cure periods;

- any representation or warranty made by the related Owner Trustee or Owner Participant, in the case of a Leased Aircraft Indenture, or Atlas, in the case of an Owned Aircraft Indenture, in such Indenture, the related Participation Agreement, or certain related documents furnished to the Loan Trustee or any holder of an Equipment Note pursuant thereto being false or incorrect in any material respect when made that continues to be material and adverse to the interests of the Loan Trustee or Note Holders and remains unremedied after notice and specified cure periods;

- failure by Atlas or the related Owner Trustee or Owner Participant to perform or observe covenants or obligations for the benefit of the Loan Trustee or holders of Equipment Notes under such Indenture or certain related documents which continues after notice and specified cure periods and which is material and adverse to the interests of the Loan Trustee or the Note Holders;

- the registration of the related Aircraft ceasing to be effective as a result of the Owner Participant (in the case of a Leased Aircraft) not being a citizen of the United States, as defined in the Transportation Code (subject to a cure period);

- with respect to the Owned Aircraft, the lapse or cancellation of insurance required under the Owned Aircraft Indenture; or

- the occurrence of certain events of bankruptcy, reorganization or insolvency of the related Owner Trustee or Owner Participant (in the case of a Leased Aircraft) or Atlas (in the case of an Owned Aircraft). (Leased Aircraft Indentures, Section 4.02; Owned Aircraft Indentures,
Section 5.01)

There will not be cross-default provisions in the Indentures or in the Leases (unless otherwise agreed between an Owner Participant and Atlas). Consequently, events resulting in an Indenture Event of Default under any particular Indenture may or may not result in an Indenture Event of Default occurring under any other Indenture, and a Lease Event of Default under any particular Lease may or may not constitute a Lease Event of Default under any other Lease.

If Atlas fails to make any semiannual basic rental payment due under any Lease, within a specified period after such failure the applicable Owner Trustee may furnish to the Leased Aircraft Trustee the amount due on the Equipment Notes issued with respect to the related Leased Aircraft, together with any interest thereon on account of the delayed payment thereof, in which event the Leased Aircraft Trustee and the holders of outstanding Equipment Notes issued under such Indenture may not exercise any remedies otherwise available under such Indenture or such Lease as the result of such failure to make such rental payment, unless such Owner Trustee has previously cured three or more immediately

63

preceding semiannual basic rental payment defaults or, in total, six or more previous semiannual basic rental payment defaults. The applicable Owner Trustee also may cure any other default by Atlas in the performance of its obligations under any Lease that can be cured with the payment of money. (Leased Aircraft Indentures, Section 4.03)

The holders of a majority in principal amount of the outstanding Equipment Notes issued with respect to any Aircraft, by notice to the Loan Trustee, may on behalf of all the holders waive any existing default and its consequences under the Indenture with respect to such Aircraft, except a default in the payment of the principal of, or premium or interest on any such Equipment Notes or a default in respect of any covenant or provision of such Indenture that cannot be modified or amended without the consent of each holder of Equipment Notes. (Leased Aircraft Indentures, Section 4.08; Owned Aircraft Indentures, Section 5.06)

REMEDIES

If an Indenture Event of Default occurs and is continuing under an Indenture, the related Loan Trustee or the holders of a majority in principal amount of the Equipment Notes outstanding under such Indenture may, subject to the applicable Owner Participant's or Owner Trustee's right to cure, as discussed above, declare the principal of all such Equipment Notes issued thereunder immediately due and payable, together with all accrued but unpaid interest thereon, provided that in the event of a reorganization proceeding involving Atlas instituted under Chapter 11 of the U.S. Bankruptcy Code, if no other Lease Event of Default and no other Indenture Event of Default (other than the failure to pay the outstanding amount of the Equipment Notes which by such declaration shall have become payable) exists at any time after the consummation of such proceeding, such declaration will be automatically rescinded without any further action on the part of any holder of Equipment Notes. The holders of a majority in principal amount of Equipment Notes outstanding under an Indenture may rescind any declaration of acceleration of such Equipment Notes at any time before the judgment or decree for the payment of the money so due shall be entered if (i) there has been paid to the related Loan Trustee an amount sufficient to pay all principal, interest, and premium, if any, on any such Equipment Notes, to the extent such amounts have become due otherwise than by such declaration of acceleration and (ii) all other Indenture Events of Default and incipient Indenture Events of Default with respect to any covenant or provision of such Indenture have been cured. (Leased Aircraft Indentures Section 4.04(b); Owned Aircraft Indentures, Section 5.02(b))

Each Indenture provides that if an Indenture Event of Default under such Indenture has occurred and is continuing, the related Loan Trustee may exercise certain rights or remedies available to it under such Indenture or under applicable law, including if, in the case of a Leased Aircraft, the corresponding Lease has been declared in default one or more of the remedies under such Lease with respect to the Aircraft subject to such Lease. If an Indenture Event of Default arises solely by reason of one or more events or circumstances which constitutes a Lease Event of Default, the related Leased Aircraft Trustee's right to exercise remedies under a Leased Aircraft Indenture is subject, with certain exceptions, to its having proceeded to exercise one or more of the dispossessory remedies under the Lease with respect to such Leased Aircraft; provided that the requirement to exercise one or more of such remedies under such Lease shall not apply in circumstances where such exercise has been involuntarily stayed or prohibited by applicable law or court order for a continuous period in excess of 60 days or such period as may be specified in
Section 1110(a)(1)(A) of the U.S. Bankruptcy Code, plus an additional period, if any, resulting from (i) the trustee or debtor-in-possession in such proceeding agreeing to perform obligations under such Lease with the approval of the applicable court and its continuous performance of such Lease under Section 1110(a)(1) (A-B) of the U.S. Bankruptcy Code or such Leased Aircraft Trustee's consent to an extension of such period, (ii) such Leased Aircraft Trustee's failure to give any requisite notice or (iii) Atlas' assumption of such Lease with the approval of the relevant court and its continuous performance of the Lease as so assumed. See "-- The Leases and Certain Provisions of the Owned Aircraft Indentures -- Events of Default Under the Leases." Such remedies may be exercised by the related Leased Aircraft Trustee to the exclusion of the related Owner Trustee, subject to certain conditions

64

specified in such Indenture and subject to the terms of such Lease. Any Aircraft sold in the exercise of such remedies will be free and clear of any rights of those parties, including the rights of Atlas under the Lease with respect to such Aircraft; provided that no exercise of any remedies by the related Leased Aircraft Trustee may affect the rights of Atlas under any Lease unless a Lease Event of Default has occurred and is continuing. (Leased Aircraft Indentures,
Section 4.04; Leases, Section 15) The Owned Aircraft Indentures will not contain such limitations on the Owned Aircraft Trustee's ability to exercise remedies upon an Indenture Event of Default under an Owned Aircraft Indenture.

If a bankruptcy proceeding involving Atlas under the U.S. Bankruptcy Code occurs, all of the rights of the Owner Trustee as lessor under a particular Lease will be exercised by the Owner Trustee in accordance with the terms thereof unless (i) during the Section 1110 Period the trustee in such proceeding or Atlas does not assume or agree to perform its obligations under such Lease,
(ii) at any time after assuming or agreeing to perform such obligations, such trustee or Atlas ceases to perform such obligations or (iii) the related Loan Trustee takes action, or notifies the Owner Trustee that such Loan Trustee intends to take action, to foreclose the lien of the related Leased Aircraft Indenture or otherwise commence the exercise of any significant remedy in accordance with the Leased Aircraft Indenture in connection with any continuing non-bankruptcy Indenture Event of Default. The Owner Trustee's exercise of such rights shall be subject to certain limitations and may not, in any event, reduce the amount or change the time of any payment in respect of the Equipment Notes or adversely affect the validity or enforceability of the lien under the related Leased Aircraft Indenture.

If the Equipment Notes issued in respect of one Aircraft are in default, the Equipment Notes issued in respect of the other Aircraft may not be in default, and, if not, no remedies will be exercisable under the applicable Indentures with respect to such other Aircraft.

Section 1110 of the U.S. Bankruptcy Code ("Section 1110") provides in relevant part that the right of lessors, conditional vendors and holders of security interests with respect to "Equipment" (as defined in Section 1110) to take possession of such Equipment in compliance with the provisions of a lease, conditional sale contract or security agreement, as the case may be, is not affected by:

- the automatic stay provision of the U.S. Bankruptcy Code, which provision enjoins repossessions by creditors for the duration of the reorganization period;

- the provision of the U.S. Bankruptcy Code allowing the trustee in reorganization to use property of the debtor during the reorganization period;

- Section 1129 of the U.S. Bankruptcy Code (which governs the confirmation of plans of reorganization in Chapter 11 cases); and

- any power of the bankruptcy court to enjoin a repossession.

Section 1110 provides in relevant part, however, that the right of a lessor, conditional vendor or holder of a security interest to take possession of an aircraft in the event of an event of default may not be exercised for 60 days following the date of commencement of the reorganization proceedings (unless specifically permitted by the bankruptcy court) and may not be exercised at all if, within such 60-day period (or such longer period consented to by the lessor, conditional vendor or holder of a security interest), the trustee in reorganization agrees to perform the debtor's obligations that become due on or after such date and cures all existing defaults (other than defaults resulting solely from the financial condition, bankruptcy, insolvency or reorganization of the debtor).

"Equipment" is defined in Section 1110, in part, as an aircraft, aircraft engine, propeller, appliance, or spare part (as defined in Section 40102 of Title 49 of the U.S. Code) that is subject to a security interest granted by, leased to, or conditionally sold to a debtor that is a citizen of the United States (as defined in Section 40102 of Title 49 of the U.S. Code) holding an air carrier operating certificate issued by the Secretary of Transportation pursuant to chapter 447 of Title 49 of the U.S. Code for aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of cargo.

65

It is a condition to the Trustee's obligation to purchase Equipment Notes with respect to each Aircraft that outside counsel to Atlas, Cahill Gordon & Reindel, provide its opinion to the Trustees that (x) if such Aircraft is a Leased Aircraft, the Owner Trustee, as lessor under the Lease for such Aircraft, and the Leased Aircraft Trustee, as assignee of such Owner Trustee's rights under such Lease pursuant to the related Leased Aircraft Indenture, will be entitled to the benefits of Section 1110 with respect to the airframe and engines comprising such Aircraft or (y) if such Aircraft is an Owned Aircraft, the Owned Aircraft Trustee will be entitled to the benefits of Section 1110 with respect to the airframe and engines comprising such Owned Aircraft, in each case, assuming that Atlas is a "citizen of the United States" as defined in
Section 40102 of Title 49 of the U.S. Code holding an air carrier operating certificate issued by the Secretary of Transportation pursuant to chapter 447 of Title 49 of the U.S. Code for aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of cargo and assuming that the Aircraft and Engines constitute "equipment" as defined in Section 1110. For a description of certain limitations on the Loan Trustee's exercise of rights contained in the Indenture, see "-- Indenture Defaults, Notice and Waiver."

The opinion of Cahill Gordon & Reindel will not address the possible replacement of an Aircraft after an Event of Loss in the future, the consummation of which is conditioned upon the contemporaneous delivery of an opinion of counsel to the effect that the related Loan Trustee will be entitled to Section 1110 benefits with respect to such replacement unless there is a change in law or court interpretation that results in Section 1110 not being available. See "-- The Leases and Certain Provisions of the Owned Aircraft Indentures -- Events of Loss." The opinion of Cahill Gordon & Reindel will also not address the availability of Section 1110 with respect to any possible sublessee of a Leased Aircraft subleased by Atlas or to any possible lessee of an Owned Aircraft if it is leased by Atlas.

The U.S. District Court for the District of Colorado in 1998 issued opinions arising from the bankruptcy proceedings of Western Pacific Airlines, Inc. relating to Section 1110. The decisions held that, once an airline debtor reaffirms its obligations and cures its defaults under an aircraft lease within the prescribed period in accordance with Section 1110, the lessor under such lease is not entitled to repossess the aircraft under Section 1110 if the airline subsequently defaults under such lease. (An appeal of these decisions to the United States Court of Appeals for the Tenth Circuit was dismissed as moot on July 7, 1999.) The opinion of Cahill Gordon & Reindel will state that, in such firm's opinion, the District Court cases were incorrectly decided, since they are contrary to the plain language of Section 1110 that requires the cure of any default (other than certain defaults relating to the bankruptcy proceedings) and are not limited to defaults occurring at the commencement of the bankruptcy proceeding. Moreover, such opinion of Cahill Gordon & Reindel will state that, in such firm's opinion, such District Court cases are contrary to the clear intent of Congress in enacting Section 1110, since they would substantially eliminate the benefit of Section 1110 by giving no effect to rights of repossession under Section 1110 after the initial reaffirmance and cure.

As a result of these decisions and the fact that Atlas is headquartered in Colorado, Standard & Poor's placed Atlas' 1998 EETCs, 1999 EETCs and 2000 EETCs on credit watch with negative implications while affirming its corporate credit rating on Atlas' unsecured debt. Standard & Poor's has placed the Certificates offered hereby on credit watch for the same reason. Standard & Poor's has stated that if remedial legislation which favorably resolves the Section 1110 uncertainty becomes law, or if the issue is favorably resolved in a court decision, ratings on the pass through trust certificates would be affirmed. Standard & Poor's has also stated that once Atlas moves its headquarters from Colorado to New York State, they expect to affirm and remove the ratings from credit watch.

If an Indenture Default under any Indenture occurs and is continuing, any sums held or received by the related Loan Trustee may be applied to reimburse such Loan Trustee for any tax, expense or other loss incurred by it and to pay any other amounts due to such Loan Trustee prior to any payments to holders of the Equipment Notes issued under such Indenture. (Indentures, Section 3.03)

In the event of bankruptcy, insolvency, receivership or like proceedings involving an Owner Participant, it is possible that, notwithstanding that the applicable Leased Aircraft is owned by the related

66

Owner Trustee in trust, such Leased Aircraft and the related Lease and Equipment Notes might become part of such proceeding. In such event, payments under such Lease or on such Equipment Notes might be interrupted and the ability of the related Leased Aircraft Trustee to exercise its remedies under the related Leased Aircraft Indenture might be restricted, although such Leased Aircraft Trustee would retain its status as a secured creditor in respect of the related Lease and the related Leased Aircraft.

MODIFICATION OF INDENTURES AND LEASES

Without the consent of holders of a majority in principal amount of the Equipment Notes outstanding under any Indenture, the provisions of such Indenture and any related Lease, Participation Agreement or Trust Agreement may not be amended or modified, except to the extent indicated below.

Subject to certain limitations, certain provisions of any Leased Aircraft Indenture, and of the Lease, the Participation Agreement, and the Trust Agreement related thereto, may be amended or modified by the parties thereto without the consent of any holders of the Equipment Notes outstanding under such Indenture. In the case of each Lease, such provisions include, among others, provisions relating to (i) the return to the related Owner Trustee of the related Leased Aircraft at the end of the term of such Lease (except to the extent that such amendment would affect the rights or exercise of remedies under the Lease) and (ii) the renewal of such Lease and the option of Atlas at the end of the term of such Lease to purchase the related Leased Aircraft so long as the same would not adversely affect the Note Holders. (Leased Aircraft Indentures,
Section 9.01(a)) In addition, any Indenture may be amended without the consent of the holders of Equipment Notes to, among other things, cure any defect or inconsistency in such Indenture or the Equipment Notes issued thereunder, provided that such change does not adversely affect the interests of any such holder. (Leased Aircraft Indentures, Section 9.01(c); Owned Aircraft Indentures,
Section 10.01)

Without the consent of each Liquidity Provider and the holder of each Equipment Note outstanding under any Indenture affected thereby, no amendment or modification of such Indenture may among other things (a) reduce the principal amount of, or premium, if any, or interest payable on, any Equipment Notes issued under such Indenture or change the date on which any principal, premium, if any, or interest is due and payable, (b) permit the creation of any security interest with respect to the property subject to the lien of such Indenture, except as provided in such Indenture, or deprive any holder of an Equipment Note issued under such Indenture of the benefit of the lien of such Indenture upon the property subject thereto or (c) reduce the percentage in principal amount of outstanding Equipment Notes issued under such Indenture required to take or approve any action under such Indenture. (Leased Aircraft Indentures, Section 9.01(b); Owned Aircraft Indentures, Section 10.01(a))

INDEMNIFICATION

Atlas will be required to indemnify each Loan Trustee, each Owner Participant, each Owner Trustee, each Liquidity Provider, the Subordination Agent, the Escrow Agent and each Trustee, but not the holders of Certificates, for certain losses, claims and other matters. Atlas will be required under certain circumstances to indemnify each Owner Participant against the loss of depreciation deductions and certain other benefits allowable for certain income tax purposes with respect to the related Leased Aircraft.

THE LEASES AND CERTAIN PROVISIONS OF THE OWNED AIRCRAFT INDENTURES

Each Leased Aircraft will be leased to Atlas by the relevant Owner Trustee under the relevant lease agreement (each, a "Lease"). Each Owned Aircraft will be owned by Atlas.

Lease Term Rentals and Payments

Each Leased Aircraft will be leased separately by the relevant Owner Trustee to Atlas for a term commencing on the date on which the Aircraft is acquired by the Owner Trustee and expiring on a date not earlier than the latest maturity date of the relevant Equipment Notes, unless terminated prior to the originally scheduled expiration date as permitted by the applicable Lease. The semiannual basic rent

67

payment under each Lease is payable by Atlas on each related Lease Payment Date (or, if such day is not a Business Day, on the next Business Day), and will be assigned by the Owner Trustee under the corresponding Leased Aircraft Indenture to provide the funds necessary to make scheduled payments of principal and interest due from the Owner Trustee on the Equipment Notes issued under such Indenture. In certain cases, the semiannual basic rent payments under the Leases may be adjusted, but each Lease provides that under no circumstances will rent payments by Atlas be less than the scheduled payments on the related Equipment Notes. Any balance of each such semiannual basic rent payment under each Lease, after payment of amounts due on the Equipment Notes issued under the Indenture corresponding to such Lease, will be paid over to the Owner Trustee. (Leases,
Section 3; Leased Aircraft Indentures, Section 3.01)

"Lease Payment Date" means, with respect to each Lease, January 2 or July 2 during the term of such Lease, the commencement date of such Lease or any other date agreed between Atlas and the Owner Participant that occurs after the latest maturity date of the Equipment Notes issued in connection with the acquisition of the Aircraft to which such Lease relates.

Semiannual payments of interest on the Equipment Notes issued by Atlas under an Owned Aircraft Indenture are payable January 2 and July 2 of each year, commencing on July 2, 2000. Semiannual payments of principal under the Equipment Notes issued by Atlas under an Owned Aircraft Indenture are payable on January 2 and July 2 in certain years, commencing on January 2, 2001.

Net Lease; Maintenance

Under the terms of each Lease, Atlas' obligations in respect of each Leased Aircraft will be those of a lessee under a "net lease." Accordingly, Atlas is obligated under each Lease, among other things and at its expense, to keep each Aircraft duly registered and insured, to pay all costs of operating the Aircraft and to maintain, service, repair and overhaul the Aircraft so as to keep it in as good operating condition as when delivered to Atlas, ordinary wear and tear excepted, and in such condition as required to maintain the airworthiness certificate for the Aircraft in good standing at all times. (Leases, Sections 7.1, 8.1 and 11.1 and Annexes C and D) The Owned Aircraft Indentures impose comparable registration, insurance, maintenance, service and repair obligations on Atlas with respect to the Owned Aircraft. (Owned Aircraft Indentures, Sections 4.02 and 4.06)

Possession, Sublease and Transfer

Each Aircraft may be operated by Atlas or, subject to certain restrictions, by certain other persons. Normal interchange and pooling agreements customary in the commercial airline industry with respect to any Engine are permitted. Subleases, in the case of the Leased Aircraft, and leases, in the case of Owned Aircraft, are also permitted to U.S. air carriers, U.S. aircraft manufacturers, foreign air carriers and foreign aircraft manufacturers that have their principal executive office in certain specified countries, subject to a reasonably satisfactory legal opinion that, among other things, such country would recognize (in the case of the Leased Aircraft) Owner Trustee's title to, and the Loan Trustee's security interest in respect of, the applicable Aircraft. In addition, a sublessee may not be subject to insolvency or similar proceedings at the commencement of such sublease or lease. (Leases, Section 7; Owned Aircraft Indentures, Section 4.02) Permitted foreign air carriers are not limited to those based in a country that is a party to the Convention on the International Recognition of Rights in Aircraft (Geneva 1948) (the "Convention"). It is uncertain to what extent the relevant Loan Trustee's security interest would be recognized if an Aircraft is registered or located in a jurisdiction not a party to the Convention. Moreover, in the case of an Indenture Event of Default, the ability of the related Loan Trustee to realize upon its security interest in an Aircraft could be adversely affected as a legal or practical matter if such Aircraft were registered or located outside the United States.

68

Registration

Atlas is required to keep each Aircraft duly registered under the Transportation Code with the FAA, except (in the case of the Leased Aircraft) if the relevant Owner Trustee or the relevant Owner Participant fails to meet the applicable citizenship requirements, and to record each Lease (in the case of the Leased Aircraft) and Indenture and certain other documents under the Transportation Code. (Leases, Section 7; Owned Aircraft Indentures, Section 4.02(e)) Such recordation of the Indenture and other documents with respect to each Aircraft will give the relevant Loan Trustee a first-priority, perfected security interest in such Aircraft whenever it is located in the United States or any of its territories and possessions. The Convention provides that such security interest will also be recognized, with certain limited exceptions, in those jurisdictions that have ratified or adhere to the Convention.

So long as no Lease Event of Default exists, Atlas has the right to register the Leased Aircraft subject to such Lease in a country other than the United States at its own expense in connection with a permitted sublease of the Aircraft to a permitted foreign air carrier, subject to certain conditions set forth in the related Participation Agreement. These conditions include a requirement that the lien of the applicable Indenture continue as a first priority security interest in the applicable Aircraft. (Leases, Section 7.1.2; Participation Agreements, Section 7.6.11) The Owned Aircraft Indentures contain comparable provisions with respect to the registration of the Owned Aircraft in connection with a permitted lease of the Owned Aircraft. (Owned Aircraft Indentures, Section 4.02(e))

Liens

Atlas is required to maintain each Aircraft free of any liens, other than the rights of the relevant Loan Trustee, the holders of the related Equipment Notes, Atlas, and, with respect to a Leased Aircraft, the Owner Participant and Owner Trustee arising under the applicable Indenture, the Lease (in the case of the Leased Aircraft) or the other operative documents related thereto, and other than certain limited liens permitted under such documents, including but not limited to (i) liens for taxes either not yet due or being contested in good faith by appropriate proceedings; (ii) materialmen's, mechanics' and other similar liens arising in the ordinary course of business and securing obligations that either are not yet delinquent for more than 60 days or are being contested in good faith by appropriate proceedings; (iii) judgment liens so long as such judgment is discharged or vacated within 60 days or the execution of such judgment is stayed pending appeal or discharged, vacated or reversed within 60 days after expiration of such stay; and (iv) any other lien as to which Atlas has provided a bond or other security adequate in the reasonable opinion of the Owner Trustee; provided that in the case of each of the liens described in the foregoing clauses (i), (ii) and (iii), such liens and proceedings do not involve any material risk of the sale, forfeiture or loss of such Aircraft or the interest of any Participant therein or impair the lien of the relevant Indenture. (Leases, Section 6; Owned Aircraft Indentures, Section 4.01)

Replacement of Parts, Alterations

Atlas is obligated to replace all parts at its expense that may from time to time be incorporated or installed in or attached to any Aircraft and that may become lost, damaged beyond repair, worn out, stolen, seized, confiscated or rendered permanently unfit for use. Atlas or any permitted sublessee has the right, at its own expense, to make such alterations, modifications and additions with respect to each Aircraft as it deems desirable in the proper conduct of its business and to remove parts which it deems to be obsolete or no longer suitable or appropriate for use, so long as such alteration, modification, addition or removal does not materially diminish the fair market value, utility or useful life of the related Aircraft or Engine or invalidate the Aircraft's airworthiness certificate. (Leases, Section 8.1 and Annex C; Owned Aircraft Indentures, Section 4.04(d))

Insurance

Atlas is required to maintain, at its expense (or at the expense of a permitted lessee, in the case of the Owned Aircraft, or a permitted sublessee, in the case of the Leased Aircraft), all-risk aircraft hull

69

insurance covering each Aircraft, at all times in an amount not less than the stipulated loss value of such Aircraft (which will exceed the aggregate outstanding principal amount of the Equipment Notes relating to such Aircraft, together with accrued interest thereon). However, after giving effect to self-insurance permitted as described below, the amount payable under such insurance may be less than such amounts payable with respect to the Equipment Notes. In the event of a loss involving insurance proceeds in excess of $7.5 million, to be adjusted for inflation, per occurrence such proceeds up to the stipulated loss value of the relevant Aircraft will be payable to the applicable Loan Trustee, for so long as the relevant Indenture shall be in effect. In the event of a loss involving insurance proceeds of up to $7.5 million, to be adjusted for inflation, per occurrence such proceeds will be payable directly to Atlas so long as an Indenture Event of Default does not exist with respect to the Owned Aircraft or (in the case of the Leased Aircraft) the Owner Trustee has not notified the insurance underwriters that a Lease Event of Default exists. So long as the loss does not constitute an Event of Loss, insurance proceeds will be applied to repair or replace the property. (Leases, Sections 11 and Annex D; Owned Aircraft Indentures, Section 4.06)

In addition, Atlas is obligated to maintain comprehensive airline liability insurance at its expense (or at the expense of a permitted lessee, in the case of the Owned Aircraft, or a permitted sublessee, in the case of the Leased Aircraft), including without limitation, passenger liability, baggage liability, cargo and mail liability, hangarkeeper's liability and contractual liability insurance with respect to each Aircraft. Such liability insurance must be underwritten by insurers of nationally or internationally recognized responsibility. The amount of such liability insurance coverage per occurrence may not be less than the amount of comprehensive airline liability insurance from time to time applicable to aircraft owned or leased and operated by Atlas of the same type and operating on similar routes as such Aircraft. (Leases,
Section 11.1 and Annex D; Owned Aircraft Indentures, Section 4.06)

Atlas is also required to maintain war-risk, hijacking or allied perils insurance if it (or any permitted sublessee or lessee) operates any Aircraft, Airframe or Engine in any area of recognized hostilities or if Atlas (or any permitted sublessee or lessee) maintains such insurance with respect to other aircraft operated on the same routes or areas on or in which the Aircraft is operated. (Leases, Annex D; Owned Aircraft Indentures, Section 4.06)

Atlas may self-insure under a program applicable to all aircraft in its fleet, but the amount of such self-insurance in the aggregate may not exceed 50% of the largest replacement value of any single aircraft in Atlas' fleet or 1 1/2% of the average aggregate insurable value (during the preceding policy year) of all aircraft on which Atlas carries insurance, whichever is less, unless an insurance broker of national standing shall certify that the standard among other major U.S. air cargo carriers is a higher level of self-insurance, in which case Atlas may self-insure the Aircraft to such higher level. In addition, Atlas may self-insure to the extent of any applicable deductible per Aircraft that does not exceed industry standards for major U.S. air cargo carriers. (Leases, Section 11.1 and Annex D; Owned Aircraft Indentures, Section 4.06 and Annex B)

In respect of each Aircraft, Atlas is required to name as additional insured parties the relevant Loan Trustee and holders of the Equipment Notes and (in the case of the Leased Aircraft) the relevant Owner Participant and Owner Trustee, in its individual capacity and as owner of such Aircraft, and the Liquidity Provider under all liability, hull and property and war risk, hijacking and allied perils insurance policies required with respect to such Aircraft. In addition, the insurance policies will be required to provide that, in respect of the interests of such additional insured persons, the insurance shall not be invalidated or impaired by any act or omission of Atlas, any permitted sublessee or any other person. (Leases, Annex D; Owned Aircraft Indentures, Section 4.06 and Annex B)

Lease Termination

Atlas may terminate any Lease on any Lease Payment Date occurring after the fifth anniversary of the date on which such Lease commenced, if it makes a good faith determination that the Leased Aircraft subject to such Lease is economically obsolete or surplus to its requirements or if it is to be disposed pursuant to a program of fleet renewal. Atlas is required to give notice of its intention to exercise its right

70

of termination described in this paragraph at least 90 days prior to the proposed date of termination, which notice may be withdrawn up to 10 Business Days prior to such proposed date; provided that Atlas may with respect to such Lease give only five such termination notices. In such a situation, unless the Owner Trustee elects to retain title to such Aircraft, Atlas is required to use commercially reasonable efforts to sell such Aircraft as an agent for such Owner Trustee. The Owner Trustee will sell such Aircraft to the highest cash bidder on the date of termination specified in Atlas' notice or on any other date within 10 Business Days of such date of termination agreed with the applicable lessor. If such sale occurs, the Equipment Notes related thereto are required to be prepaid. If the net proceeds to be received from such sale are less than the termination value for such Aircraft (which is set forth in a schedule to each Lease), Atlas is required to pay to the applicable Owner Trustee an amount equal to the excess, if any, of the applicable termination value for such Aircraft over such net proceeds. Upon payment of termination value for such Aircraft and an amount equal to the Make-Whole Premium, if any, payable on such date of payment, together with certain additional amounts, the lien of the relevant Indenture will be released, the relevant Lease will terminate, and the obligation of Atlas thereafter to make scheduled rent payments under such Lease will cease. (Leases, Section 9; Leased Aircraft Indentures, Section 2.10(b))

The Owner Trustee has the option to retain title to the Leased Aircraft if Atlas has given a notice of termination under the Lease. In such event, such Owner Trustee will pay to the applicable Loan Trustee an amount sufficient to prepay the outstanding Equipment Notes issued with respect to such Aircraft (including the Make-Whole Premiums), in which case the lien of the relevant Indenture will be released, the relevant Lease will terminate and the obligation of Atlas thereafter to make scheduled rent payments under such Lease will cease.
(Leases, Section 9; Leased Aircraft Indentures, Sections 2.06 and 2.10(b))

Events of Loss

If an Event of Loss occurs with respect to the Airframe or the Airframe and Engines of an Aircraft, Atlas must elect within 60 days after such occurrence either to make payment with respect to such Event of Loss or to replace such Airframe and any such Engines. If Atlas elects to make payment with respect to such Event of Loss, then such payment shall be made on or before the earlier of
(i) the Business Day next following the 180th day after the date of occurrence of such Event of Loss, and (ii) the Business Day specified as the payment date in an irrevocable notice delivered by Atlas not less than 20 days prior to such payment date. The amount of such payment shall include the outstanding principal amount of the Equipment Notes (in the case of an Owned Aircraft) or the stipulated loss value of such Aircraft (in the case of a Leased Aircraft), together with certain additional amounts, but shall exclude any Make-Whole Premium. If Atlas elects to replace such Airframe and any such Engines, Atlas must, within 180 days after the date of occurrence of such Event of Loss, substitute an airframe (or airframe and one or more engines, as the case may be) for the Airframe or Airframe and Engines that suffered such Event of Loss. Notwithstanding the foregoing, if an Indenture Event of Default or failure to pay principal or interest under the Owned Aircraft Indenture has occurred and is continuing or certain bankruptcy defaults have occurred and are continuing, Atlas shall be required to make payment with respect to such Event of Loss. (Leases, Sections 10.1.1 and 10.1.2; Leased Aircraft Indentures, Section 2.10(a); Owned Aircraft Indentures, Section 2.10 and 4.05(a))

If Atlas elects to replace an Airframe (or Airframe and one or more Engines, as the case may be) that suffered such Event of Loss, it shall, in the case of the Leased Aircraft, convey to the related Owner Trustee title to an airframe (or airframe and one or more engines, as the case may be) or, in the case of an Owned Aircraft, subject such an airframe (or airframe and one or more engines) to the lien of the Owned Aircraft Indenture, and such replacement airframe or airframe and engines must be the same model as the Airframe or Airframe and Engines to be replaced or an improved model, with a value, utility and remaining useful life (without regard to hours or cycles remaining until the next regular maintenance check) at least equal to the Airframe or Airframe and Engines to be replaced, assuming that such Airframe and such Engines had been maintained in accordance with the related Lease or Owned Aircraft Indenture, as the case may be. Atlas is also required to provide to the relevant Loan Trustee and (in the case of a Leased Aircraft) the relevant Owner Trustee and Owner Participant reasonably acceptable

71

opinions of counsel to the effect, among other things, that (i) certain specified documents have been duly filed under the Transportation Code and (ii) such Owner Trustee and Leased Aircraft Trustee (as assignee of lessor's rights and interests under the Lease), in the case of a Leased Aircraft, or the Owned Aircraft Trustee, in the case of an Owned Aircraft, will be entitled to receive the benefits of Section 1110 of the U.S. Bankruptcy Code with respect to any such replacement airframe (unless, as a result of a change in law or court interpretation, such benefits are not then available). (Leases, Sections 10.1.3 and 10.3; Owned Aircraft Indentures, Section 4.05(c))

If Atlas elects not to replace such Airframe, or Airframe and Engine(s), then upon payment of the outstanding principal amount of the Equipment Notes issued with respect to such Aircraft (in the case of an Owned Aircraft) or the stipulated loss value for such Aircraft (in the case of a Leased Aircraft), together with all additional amounts then due and unpaid with respect to such Aircraft, which must be at least sufficient to pay in full as of the date of payment thereof the aggregate unpaid principal amount under such Equipment Notes together with accrued but unpaid interest thereon and all other amounts due and owing in respect of such Equipment Notes (but without any Make-Whole Premium), the lien of the Indenture and (in the case of a Leased Aircraft) the Lease relating to such Aircraft shall terminate with respect to such Aircraft, the obligation of Atlas thereafter to make the scheduled rent payments (in the case of a Leased Aircraft) or interest and principal payments (in the case of an Owned Aircraft) with respect thereto shall cease and the related Owner Trustee shall transfer all of its right, title and interest in and to the related Aircraft to Atlas. The stipulated loss value and other payments made under the Leases or the Owned Aircraft Indenture, as the case may be, by Atlas shall be deposited with the applicable Loan Trustee. Amounts in excess of the amounts due and owing under the Equipment Notes issued with respect to such Aircraft will be distributed by such Loan Trustee to the applicable Owner Trustee or to Atlas, as the case may be. (Leases, Section 10.1.2; Leased Aircraft Indentures, Sections 2.06 and 3.02; Owned Aircraft Indentures, Section 4.05(a)(ii))

If an Event of Loss occurs with respect to an Engine alone, Atlas will be required to replace such Engine within 90 days after the occurrence of such Event of Loss with another engine, free and clear of all liens (other than certain permitted liens). Such replacement engine shall be the same make and model as the Engine to be replaced, or an improved model, suitable for installation and use on the Airframe, and having a value, utility and remaining useful life (without regard to hours or cycles remaining until overhaul) at least equal to the Engine to be replaced, assuming that such Engine had been maintained in accordance with the relevant Lease or the Owned Aircraft Indenture, as the case may be. (Leases, Section 10.2; Owned Aircraft Indenture,
Section 4.04(e))

An "Event of Loss" with respect to an Aircraft, Airframe or any Engine means any of the following events with respect to such property:

- the destruction of such property, damage to such property beyond economic repair or rendition of such property permanently unfit for normal use;

- the actual or constructive total loss of such property or any damage to such property or requisition of title or use of such property which results in an insurance settlement with respect to such property on the basis of a total loss or a constructive or compromised total loss;

- any theft, hijacking or disappearance of such property for a period of 180 consecutive days or more;

- any seizure, condemnation, confiscation, taking or requisition of title to such property by any governmental entity or purported governmental entity (other than a U.S. government entity or an entity of the country of registration of the relevant Aircraft) for a period exceeding 180 consecutive days or, if earlier, at the end of the term of such Lease (in the case of a Leased Aircraft) or the final maturity of the Equipment Notes (in the case of an Owned Aircraft);

- in the case of any Leased Aircraft, any seizure, condemnation, confiscation, taking or requisition of use of such property by any U.S. government entity (or governmental entity of the country of registration of the relevant Aircraft) that continues until the 30th day after the last day of the term

72

of the relevant Lease (unless the Owner Trustee shall have elected not to treat such event as an Event of Loss);

- as a result of any law, rule, regulation, order or other action by the FAA or any governmental entity, the use of such property in the normal course of Atlas' business of air cargo transportation is prohibited for 180 consecutive days, unless Atlas, prior to the expiration of such 180-day period, shall have undertaken and shall be diligently carrying forward steps which are necessary or desirable to permit the normal use of such property by Atlas, but in any event if such use shall have been prohibited for a period of two consecutive years, provided that no Event of Loss shall be deemed to have occurred if such prohibition has been applicable to Atlas' entire U.S. registered fleet of similar property and Atlas, prior to the expiration of such two-year period, shall have conformed at least one unit of such property in its fleet to the requirements of any such law, rule, regulation, order or other action and commenced regular commercial use of the same and shall be diligently carrying forward, in a manner which does not discriminate against applicable property in so conforming such property, steps which are necessary or desirable to permit the normal use of such property by Atlas, but in any event if such use shall have been prohibited for a period of three years or, in the case of a Leased Aircraft, such use shall be prohibited at the expiration of the term of the relevant Lease; or

- with respect to any Engine, any divestiture of title to such Engine shall be treated as an Event of Loss. (Leases, Section 7.2.6 and Annex A; Owned Aircraft Indentures, Annex A)

Renewal and Purchase Options

At the end of the term of each Lease after final maturity of the related Equipment Notes and subject to certain conditions, Atlas will have the option to renew such Lease for additional limited periods (each a "Renewal Term"). Each Renewal Term shall be for not less than three months and not more than 2 years, as determined by Atlas. Rent payments during the first Renewal Term shall equal the lesser of fair market rental and a fixed rate rental as specified in the Lease. Rent payments during subsequent Renewal Terms shall equal fair market rental (Leases, Section 17.2).

In addition, Atlas will have the right (i) at the end of the term of each Lease, (ii) at the end of each Renewal Term, (iii) on specified dates prior to the end of the term of each Lease and (iv) upon certain tax events, to purchase the Aircraft from the applicable Owner Trustee and assume as direct obligations of Atlas, the Equipment Notes with respect to such Aircraft. In such case, the Leased Aircraft Indenture relating to such Equipment Notes will be amended and restated to be substantially the same as an Owned Aircraft Indenture. Such assumption may occur only if, Atlas has (i) indemnified the then existing beneficial owners of Certificates against any incremental U.S. federal income taxes that may be imposed on them as a direct consequence of such assumption (including any taxes that may be imposed as a result of the payment of such indemnification) and (ii) if such an opinion can be given, provided an opinion of counsel to the effect that holders of such Equipment Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such assumption and will be subject to U.S. federal income tax on the same amount and in the same manner and at the same time as would have been the case if such assumption had not occurred. See "Certain U.S. Federal Income Tax Consequences -- Taxation of Certificateholders Generally" for a discussion of certain tax consequences of such purchase and assumption under current regulations.

Events of Default Under the Leases

Lease Events of Default under each Lease include among other things:

- failure by Atlas to make any payment of basic rent, renewal rent, stipulated loss value or termination value under such Lease within 10 Business Days after the same shall have become due, or failure by Atlas to pay any other amount due under such Lease or under any other related operative document (other than excluded payments (as defined in the Lease)) within 10 Business

73

Days from and after the date of any written notice from the Owner Trustee or Loan Trustee of the failure to make such payment when due;

- failure by Atlas to make any excluded payment (as defined in the Lease) within 10 Business Days after written notice that such failure constitutes a Lease Event of Default is given by the relevant Owner Participant to Atlas and the relevant Loan Trustee;

- failure by Atlas to carry and maintain insurance on and in respect of the Aircraft, Airframe and Engines, in accordance with the provisions of such Lease;

- failure by Atlas to perform or observe in any material respect any other covenant or agreement to be performed or observed by it under such Lease or the related Participation Agreement or any other related operative document (other than the related tax indemnity agreement between Atlas and the Owner Participant), and such failure shall continue unremedied for a period of 30 days after written notice of such failure by the applicable Owner Trustee or Loan Trustee unless such failure is capable of being corrected and Atlas shall be diligently proceeding to correct such failure, in which case there shall be no Lease Event of Default unless and until such failure shall continue unremedied for a period of 180 days after the receipt of such notice;

- any representation or warranty made by Atlas in such Lease or the related Participation Agreement or in any other related operative document (other than in the related tax indemnity agreement between Atlas and the Owner Participant) shall prove to have been untrue or inaccurate in any material respect at the time made, such representation or warranty is material at the time in question and the same shall remain uncured (to the extent of the adverse impact thereof) for more than 30 days after the date of written notice thereof to Atlas; and

- the occurrence of certain voluntary events of bankruptcy, reorganization or insolvency of Atlas or the occurrence of involuntary events of bankruptcy, reorganization or insolvency which shall continue undismissed, unvacated or unstayed for a period of 90 days. (Leases,
Section 14)

Indenture Events of Default under the Owned Aircraft Indentures are discussed above under "-- Indenture Defaults, Notice and Waiver."

Remedies Exercisable upon Events of Default Under the Leases

If a Lease Event of Default has occurred and is continuing, the applicable Owner Trustee may (or, so long as the Indenture shall be in effect, the applicable Loan Trustee may, subject to the terms of the Indenture) exercise one or more of the remedies provided in such Lease with respect to the related Aircraft. These remedies include the right to repossess and use or operate such Aircraft, to rescind or terminate such Lease, to sell or re-lease such Aircraft free and clear of Atlas' rights, except as set forth in the Lease, and retain the proceeds, and to require Atlas to pay, as liquidated damages any due and unpaid basic rent plus an amount equal to, at such Owner Trustee's (or, subject to the terms of the relevant Leased Aircraft Indenture, the Leased Aircraft Trustee's) option, either (i) the excess of the present value of all unpaid rent during the remainder of the term of such Lease over the present value of the fair market rental value of such Aircraft for the remainder of the term of such Lease or, (ii) the excess of the stipulated loss value of such Aircraft over the fair market sales value of such Aircraft or, if such Aircraft has been sold, the net sales proceeds from the sale of such Aircraft. (Leases, Section 15; Leased Aircraft Indentures, Section 4.04) If the Loan Trustee has validly terminated such Lease, the Loan Trustee may not sell or lease or otherwise afford the use of such Aircraft to Atlas or any of its affiliates. (Leased Aircraft Indentures, Sections 4.03 and 4.04(a))

Remedies under the Owned Aircraft Indentures are discussed above under "Description of the Equipment Notes -- Remedies."

74

Transfer of Owner Participant Interests

Subject to certain restrictions, each Owner Participant may transfer all or any part of its interest in the related Leased Aircraft. (Participation Agreements, Section 10.1.1)

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

GENERAL

The following summary describes the material U.S. federal income tax consequences to Certificateholders of the exchange of the Old Certificates for the New Certificates pursuant to the Exchange Offer. Except as otherwise specified, the summary is addressed to beneficial owners of Certificates that are citizens or residents of the United States, corporations, partnerships or other entities created or organized in or under the laws of the United States or any state therein, estates the income of which is subject to U.S. federal income taxation regardless of its source, and trusts that meet the following two tests:
(a) a U.S. court is able to exercise primary supervision over the administration of the trust and (b) one or more U.S. persons have the authority to control all substantial decisions of the trust that will hold the Certificates as capital assets. The summary does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a decision to exchange the Old Certificates for the New Certificates. This summary does not describe any tax consequences arising under the laws of any state, locality or taxing jurisdiction other than the United States.

The exchange of the Old Certificates for the New Certificates pursuant to the Exchange Offer will not be a taxable event for U.S. federal income tax purposes. The receipt of New Certificates in the exchange will be treated as a continuation of the original investment in the Old Certificates. As a result, no gain or loss will be recognized by a holder of the Old Certificates upon receipt of the New Certificates. A holder's tax basis in the New Certificates received pursuant to the Exchange Offer will be the same as the holder's tax basis in the Old Certificates exchanged therefor. A holder's holding period for the New Certificates received pursuant to the Exchange Offer will include its holding period for the Old Certificates exchanged therefor.

The summary is based upon the tax laws and practice of the United States as in effect on the date of this prospectus, as well as judicial and administrative interpretations thereof available on or before such date. All of the foregoing are subject to change, which change could apply retroactively. Certificate holders should note that no rulings have been sought from the U.S. Internal Revenue Service (the "IRS") with respect to the tax consequences described above, and no assurance can be given that the IRS will not take contrary positions.

The foregoing summary of U.S. federal tax consequences is for general information only and is not tax advice. CERTIFICATEHOLDERS ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF EXCHANGING THE OLD CERTIFICATES FOR THE NEW CERTIFICATES AND THE OWNERSHIP AND DISPOSITION OF THE NEW CERTIFICATES RECEIVED IN THE EXCHANGE OFFER IN LIGHT OF THEIR OWN PARTICULAR CIRCUMSTANCES.

ERISA CONSIDERATIONS

The Employee Retirement Income Security Act of 1974, as amended ("ERISA") imposes certain requirements on employee benefit plans subject to Title I of ERISA ("ERISA Plans"), and on those persons who are fiduciaries with respect to ERISA Plans. Investments by ERISA Plans are subject to ERISA's general fiduciary requirements, including, but not limited to, the requirement of investment prudence and diversification and the requirement that an ERISA Plan's investments be made in accordance with the documents governing the Plan.

Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of an ERISA Plan (as well as those plans that are not subject to ERISA but which are subject to

75

Section 4975 of the Code, such as individual retirement accounts (together with ERISA Plans, "Plans")) and certain persons (referred to as "parties in interest" or "disqualified persons") having certain relationships to such Plans, unless a statutory or administrative exemption is applicable to the transaction. A party in interest or disqualified person who engages in a prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code.

The Department of Labor has promulgated a regulation, 29 CFR Section 2510.3-101 (the "Plan Asset Regulation"), describing what constitutes the assets of a Plan with respect to the Plan's investment in an entity for purposes of ERISA and Section 4975 of the Code. Under the Plan Asset Regulation, if a Plan invests (directly or indirectly) in a New Certificate, the Plan's assets will include both the New Certificate and an undivided interest in each of the underlying assets of the corresponding Trust, including the Equipment Notes held by such Trust, unless it is established that equity participation in the Trust by employee benefit plans (including Plans and entities whose underlying assets include Plan assets by reason of an employee benefit plan's investment in the entity) is not "significant" within the meaning of the Plan Asset Regulation. In this regard, the extent to which there is equity participation in a particular Trust by, or on behalf of, employee benefit plans will not be monitored. If the assets of a Trust are deemed to constitute the assets of a Plan, transactions involving the assets of such Trust could be subject to the prohibited transaction provisions of ERISA and Section 4975 of the Code unless a statutory or administrative exemption is applicable to the transaction.

The fiduciary of a Plan that proposes to acquire and hold any New Certificates should consider, among other things, whether such acquisition and holding may involve (i) the direct or indirect extension of credit to a party in interest or a disqualified person, (ii) the sale or exchange of any property between a Plan and a party in interest or a disqualified person, and (iii) the transfer to, or use by or for the benefit of, a party in interest or a disqualified person, of any Plan assets. Such parties in interest or disqualified persons could include, without limitation, Atlas and its affiliates, the Owner Participants, the Underwriters, the Trustees, the Escrow Agent, the Depositary, the Owner Trustees and the Liquidity Provider. In addition, whether or not the assets of a Trust are deemed to be Plan assets under the Plan Asset Regulation, if New Certificates are acquired by a Plan and Certificates of another Class are held by a party in interest or a disqualified person with respect to such Plan, the exercise by the holder of such other Class of Certificates of its right to purchase another Class of Certificates upon the occurrence and during the continuation of a Triggering Event could be considered to constitute a prohibited transaction unless a statutory or administrative exemption were applicable. Depending on the identity of the Plan fiduciary making the decision to acquire or hold New Certificates on behalf of a Plan, Prohibited Transaction Class Exemption ("PTCE") 91-38 (relating to investments by bank collective investment funds), PTCE 84-14 (relating to transactions effected by a "qualified professional asset manager"), PTCE 95-60 (relating to investments by an insurance company general account), PTCE 96-23 (relating to transactions directed by an in-house professional asset manager) or PTCE 90-1
(relating to investments by insurance company pooled separate accounts)
(collectively, the "Class Exemptions") could provide an exemption from the prohibited transaction provisions of ERISA and Section 4975 of the Code. However, there can be no assurance that any of these Class Exemptions or any other exemption will be available with respect to any particular transaction involving the New Certificates.

Governmental plans and certain church plans, while not subject to the fiduciary responsibility provisions of ERISA or the provisions of Section 4975 of the Code, may nevertheless be subject to state or other federal laws that are substantially similar to the foregoing provisions of ERISA and the Code. Fiduciaries of any such plans should consult with their counsel before acquiring any New Certificates.

Any Plan fiduciary which proposes to cause a Plan to acquire any New Certificates should consult with its counsel regarding the applicability of the fiduciary responsibility and prohibited transaction provisions of ERISA and
Section 4975 of the Code to such an investment, and to confirm that such acquisition and holding will not constitute or result in a non-exempt prohibited transaction or any other violation of an applicable requirement of ERISA.

76

In addition to the Class Exemptions referred to above, an individual exemption may apply to the purchase, holding and secondary market sale of Class A Certificates by Plans, provided that certain specified conditions are met. In particular, the Department of Labor has issued individual administrative exemptions to certain of the Initial Purchasers which are substantially the same as the administrative exemption issued to Morgan Stanley & Co. Incorporated, Prohibited Transaction Exemption 90-24 (55 Fed. Reg. 20,548 (1990)), as amended (the "Underwriter Exemption"). The Underwriter Exemption generally exempts from the application of certain, but not all, of the prohibited transaction provisions of Section 406 of ERISA and Section 4975 of the Code certain transactions relating to the initial purchase, holding and subsequent secondary market sale of pass through certificates which represent an interest in a trust that holds secured credit instruments that bear interest or are purchased at a discount in transactions by or between business entities (including equipment notes secured by leases) and certain other assets, provided that certain conditions set forth in the Underwriter Exemption are satisfied.

The Underwriter Exemption sets a number of general and specific conditions which must be satisfied for a transaction involving the initial purchase, holding or secondary market sale of Class A Certificates to be eligible for exemptive relief thereunder. In particular, the acquisition of Class A Certificates by a Plan must be on terms that are at least as favorable to the Plan as they would be in an arm's-length transaction with an unrelated party; the rights and interests evidenced by the Certificates must not be subordinated to the rights and interests evidenced by other Certificates of the same trust estate; the Certificates at the time of acquisition by the Plan must be rated in one of the three highest generic rating categories by Moody's, Standard & Poor's or Duff & Phelps; and the investing Plan must be (and by its acquisition or acceptance of a Certificate or an interest therein, would be deemed to have represented that it is) an accredited investor as defined in Rule 501(a)(1) of Regulation D of the Commission under the Securities Act.

In addition, the trust corpus generally must be invested in qualifying receivables, such as the Equipment Notes, but may not in general include a pre-funding account (except for a limited amount of pre-funding which is invested in qualifying receivables within a limited period of time following the closing not to exceed three months).

With respect to the investment restrictions set forth in the Underwriter Exemption, an investment in a Certificate will evidence both an interest in the respective Trust as well as an interest in the Deposits held in escrow by an Escrow Agent for the benefit of the Certificateholder. Under the terms of the Escrow Agreement, the proceeds from the offering of the Old Certificates of each Class were paid over by the Initial Purchasers to the Depositary on behalf of the Escrow Agent (for the benefit of such Certificateholders as the holders of the Escrow Receipts) and do not constitute property of the Trusts. Under the terms of each Escrow Agreement, the Escrow Agent is irrevocably instructed to enter into the Deposit Agreements with the Depositary and to effect withdrawals upon the receipt of appropriate notice from the relevant Trustee so as to enable such Trustee to purchase the identified Equipment Notes on the terms and conditions set forth in the Note Purchase Agreement. Interest on the Deposits relating to each Trust will be paid to the Certificateholders of such Trust as Receiptholders through a Paying Agent appointed by the Escrow Agent. Pending satisfaction of such conditions and withdrawal of such Deposits, the Escrow Agent's rights with respect to the Deposits will remain plan assets subject to the fiduciary responsibility and prohibited transaction provisions of ERISA and
Section 4975 of the Code.

There can be no assurance that the Department of Labor would agree that the Underwriter Exemption will be applicable to Class A Certificates in these circumstances. In particular, the Department of Labor might assert that the escrow arrangement is tantamount to an impermissible pre-funding rendering the Underwriter Exemption inapplicable. In addition, even if all of the conditions of the Underwriter Exemption are satisfied with respect to the Class A Certificates, no assurance can be given that the Underwriter Exemption would apply with respect to all transactions involving the Class A Certificates or the assets of the Class A Trust. In particular, it appears that the Underwriter Exemption would not apply to the purchase by Certificateholders of another Class of Certificates in connection with the exercise of their rights upon the occurrence and during the continuance of a Triggering Event. Therefore, the fiduciary of a Plan considering the purchase of a Class A Certificate should consider the

77

availability of the exemptive relief provided by the Underwriter Exemption, as well as the availability of any other exemptions that may be applicable.

The Underwriter Exemption does not apply to the Class B or Class C Certificates.

Each person who acquires or accepts a New Certificate or an interest therein will be deemed by such acquisition or acceptance to have represented and warranted that either: (i) no Plan assets have been used to purchase such New Certificate or an interest therein or (ii) the purchase and holding of such New Certificate or interest therein are exempt from the prohibited transaction restrictions of ERISA and the Code pursuant to one or more prohibited transaction statutory or administrative exemptions.

Each Plan fiduciary (and each fiduciary for a governmental or church plan subject to rules similar to those imposed on Plans under ERISA) should consult with its legal advisor concerning an investment in any of the New Certificates.

PLAN OF DISTRIBUTION

Each broker-dealer that receives New Certificates for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Certificates. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of New Certificates received in exchange for Old Certificates where such Old Certificates were acquired as a result of market-making activities or other trading activities. Atlas has agreed that for a period of one hundred eighty (180) days after the Expiration Date, it will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

Atlas will not receive any proceeds from any sale of New Certificates by broker-dealers. New Certificates received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time on one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the New Certificates or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such New Certificates. Any broker-dealer that resells New Certificates that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such New Certificates may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of New Certificates and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The Letter of Transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

For a period of one hundred eighty (180) days after the Expiration Date, Atlas will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. Atlas has agreed to pay all expenses incident to the Exchange Offer other than commissions or concessions of any brokers or dealers and will indemnify the holders of the Certificates (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

APPENDIX B -- APPRAISAL LETTERS

84

December 21, 1999

Mr. Fred deLeeuw
Director, Corporate Finance
Atlas Air, Inc.
538 Commons Drive
Golden, Colorado 80401

Dear Mr. deLeeuw:

AvSOLUTIONS is pleased to provide this opinion on the base value, as of December 1999, of two Boeing 747-400F aircraft (the aircraft). The Boeing 747-400F aircraft are powered by General Electric CF6-80C2B5F engines. The two aircraft will be delivered new to Atlas Air, Inc. during the third quarter of 2000. A listing of the aircraft is provided as attachment 1 of this document.

Set forth below is a summary of the methodology, considerations and assumptions utilized in this appraisal.

BASE VALUE

Base value is the appraiser's opinion of the underlying economic value of an aircraft in an open, unrestricted, stable market environment with a reasonable balance of supply and demand, and assumes full consideration of its "highest and best use". An aircraft's base value is founded in the historical trend of values and in the projection of future value trends and presumes an arm's length, cash transaction between willing, able and knowledgeable parties, acting prudently, with an absence of duress and with a reasonable period of time available for marketing.

CURRENT FAIR MARKET VALUE

According to the International Society of Transport Aircraft Trading's (ISTAT) definition of Fair Market Value (FMV), to which AvSOLUTIONS subscribes, the quoted FMV is the appraiser's opinion of the most likely trading price that may be generated for an aircraft under the market circumstances that are perceived to exist at the time in question. The fair market value assumes that the aircraft is valued for its highest and best use, that the parties to the hypothetical sales transaction are willing, able, prudent and knowledgeable, and under no unusual pressure for a prompt sale, and that the transaction would be negotiated in an open and unrestricted market on an arm's length basis, for cash equivalent consideration, and given an adequate amount of time for effective market exposure to prospective buyers, which AvSOLUTIONS considers to be ten to eighteen months.

APPRAISAL METHODOLOGY

The method employed by AvSOLUTIONS to appraise the current and future values of aircraft and the associated equipment addresses the factors that influence the market value of an aircraft, such as its age, condition, configuration, the population of similar aircraft, similar aircraft on the market, operating costs, cost to acquire a new aircraft, and the state of demand for transportation services.

To achieve this objective, cross-sectional data concerning the values of aircraft in each of several general categories is collected and analyzed. Cross-sectional data is then postulated and compared with reported market values at a specified point in time. Such data reflects the effect of deterioration in aircraft performance due to usage and exposure to the elements, as well as the effect of obsolescence due to the evolutionary development and implementation of new designs and materials.

The product of the analysis identifies the relationship between the value of each aircraft and its characteristics, such as age, model designation, service configuration and engine type. Once the relationship is identified, one can then postulate the effects of the difference between the economic circumstances at the time when the cross-sectional data were collected and the current situation. Therefore, if one can determine the current value of an aircraft in one category, it is possible to estimate the current values of all aircraft in that category.

The manufacturer and size of the aircraft usually determine the specific category to which it is assigned. Segregating the world airplane fleet in this manner accommodates the potential effects of different size and different design philosophies.

The variability of the data used by AvSOLUTIONS to determine the current and future market values implies that the actual value realized will fall within a range of values. Therefore, if a contemplated value falls within the specified confidence range, AvSOLUTIONS cannot reject the hypothesis that it is a reasonable representation of the current market situation.

LIMITING CONDITIONS AND ASSUMPTIONS

In order to conduct this valuation, AvSOLUTIONS is solely relying on information as supplied by Atlas Air, Inc., and from data within AvSOLUTIONS' own database. In determining the base value of the subject Boeing 747-400F aircraft, the following assumptions have been researched and determined.

1. AvSOLUTIONS has not inspected these aircraft or their maintenance records; accordingly, AvSOLUTIONS cannot attest to their specific location or condition.

2. The aircraft will be delivered new to Atlas Air, Inc. during the third quarter of 2000.

3. The aircraft will be certified, maintained and operated under United States Federal Aviation Regulation (FAR) part 121.

4. All mandatory inspections and Airworthiness Directives have been complied with.

5. The aircraft have no damage history.

6. The aircraft are in good condition.

7. AvSOLUTIONS considers the economic useful life of these aircraft to be at least 37 years.

Based upon the above methodology, considerations and assumptions, it is AvSOLUTIONS' opinion that the base values of each aircraft are as listed in attachment 1.

I. INTRODUCTION AND EXECUTIVE SUMMARY

MORTEN BEYER & AGNEW (MBA) has been retained by Atlas Air, Inc. to determine the Current Base Value (CBV) of (2) Boeing 747-400 Freighter aircraft, delivered new. The aircraft are further identified in Section II of this report.

In performing this valuation we did not inspect the aircraft or their historical maintenance documentation, and we relied solely on information provided to us by Atlas Air. Based on the information set forth further in this report, it is our opinion that the CBV of the total value of aircraft in this portfolio is $322,870,000 with their respective individual values noted in
Section IV.

MBA uses the definition of certain terms, such as CMV and Base Value (BV), as promulgated by the International Society of Transport Aircraft Trading (ISTAT), a non-profit association of management personnel from banks, leasing companies, airlines, manufacturers, appraisers, brokers, and others who have a vested interest in the commercial aviation industry.

ISTAT defines CMV as the appraiser's opinion of the most likely trading price that may be generated for an aircraft under market conditions that are perceived to exist at the time in question. Market Value (MV) assumes that the aircraft is valued for its highest, best use; that the parties to the hypothetical sale transaction are willing, able, prudent and knowledgeable and under no unusual pressure for a prompt sale; and that the transaction would be negotiated in an open and unrestricted market on an arm's-length basis, for cash or equivalent consideration, and given an adequate amount of time for effective exposure to prospective buyers.

The ISTAT definition of Base Value (BV) has, essentially, the same elements of MV except that the market circumstances are assumed to be in a reasonable state of equilibrium. Thus, BV pertains to an idealized aircraft and market combination, but will not necessarily reflect the actual CMV of the aircraft in question. BV is founded in the historical trend of values and is generally used to analyze historical values or to project future values.

Re: Value Opinion of Two Boeing 747-400 Freighters

Dear Mr. deLeeuw:

Simat, Helliesen & Eichner, Inc ("SH&E") was asked by Atlas Air (the "Client") to determine the Base Value ("BV") of two Boeing 747-400 Freighter aircraft operated by Atlas Air (the "Subject Aircraft"). The specifications for the Subject Aircraft are referenced herein.

SH&E has determined the aggregate Base Value of the Subject Aircraft to be US$306.7 million.

AIRCRAFT DESCRIPTION

The Boeing 747 was launched in 1966 and first entered passenger service with Pan Am in January 1970. At an overall length of 231 ft. and 380-passenger capacity, the 747-100 was the largest commercial aircraft available and revolutionized the commercial air travel industry.

In 1971 Boeing launched the 747-200, realizing that the 747-100 lacked sufficient range to serve the Pacific on a nonstop basis without incurring a significant payload penalty. While similar in appearance to the 747-100, the 747-200 incorporated increased fuel capacity and more powerful engines with increased fuel efficiency. The Maximum Gross Takeoff Weight ("MTOW") was initially increased from 730,000 pounds to 775,000 pounds and later to 833,000 pounds. The range was increased to 7,000 nautical miles and, apart from the 747, the only other aircraft that approach this range capability are 777s, MD-11s and A340s.

In 1980, Boeing offered the Stretched Upper Deck ("SUD") modification for the new 747-100 and the existing 747-200 aircraft, bridging the standard 747-200 with the 747-300. The SUD modification involved extending the upper deck area by 23 ft and removing the circular stairway, thereby increasing passenger capacity by approximately 44 seats. The 747-200 SUD and the 747-300 are nearly identical, with the exception of minor doorway and window modifications.

Boeing began development of the 747-400 in May of 1985 and Northwest Airlines took delivery of its first 747-400 aircraft on January 26, 1989. Compared to previous derivatives, the 747-400 represents a major improvement over its predecessors through its enhanced technology, economic efficiencies and performance.

Externally, the 747-400 looks similar to its -300 predecessor, sharing the -300's Stretched Upper Deck. The most noticeable modifications are the 6-ft winglets that enhance aerodynamic performance and fuel efficiency. Boeing also upgraded the cockpit with digital avionics and eliminated the flight engineer position in the cockpit. The 747-400 cabin is identical in size to the 747-300 with a 416-passenger capacity in a standard configuration. With an increased fuel capacity of 383,800 pounds and a MTOW of 875,000


pounds, the 747-400 has long distance range capability of approximately 7,400 nautical miles, which is most closely matched by the Airbus A340.

The 747-400F is the freighter version of the 747-400. The aircraft the same with a shorter upper deck than the passenger version. It has the same MTOW as the passenger variant, but with a shorter range of 4,400 nm. The maximum landing weight and maximum zero-fuel weight are both greater for the 747-400F with a maximum payload of 249,125 lb. A modification of the 747-400F to a passenger version is being studied by Boeing and is labeled 747-200X. The aircraft can hold 30 96" by 125" pallets in its upper deck and 32 LD-1 containers in its lower deck. Currently there is no aircraft that completes with the 747-400F given its payload/range capabilities.

Foreseeing a requirement for increased range and capacity, Boeing was developing a new 747 series, numbered -500X and -600X, that would have carried 550 passengers increased the maximum range to approximately 8,700 nm. However, Boeing suspended development of this series in 1997 citing limited customer demand. Airbus, on the other hand, has publicly stated that it will continue development of the A3XX, an aircraft type with similar passenger and range capabilities and recently began soliciting firm orders from potential launch customers.

As of October 1999, 35 747-400Fs were operated by six airlines worldwide and a further 74 are on order.

SH&E VALUATION METHODOLOGY

SH&E's appraisal's are performed according to the International Society of Transport Aircraft Trading ("ISTAT") principles of appraisal practice and code of ethics.

The SH&E valuation approach starts by determining a half-life value. The term 'half-life' represents an aircraft whose major components, the airframe, engines, landing gear and APU have used 50 percent of the time between scheduled or expected overhauls. If appropriate, this initial appraisal can then be adjusted, positively or negatively for each individual unit to reflect the aircraft's maintenance status relative to the next overhaul. In most cases, the Base Value of an aircraft assumes its physical condition is average for an aircraft of its type and age, and its maintenance times status is at half-life, or benefiting from an above-average maintenance status if it is new or nearly new, as the case may be. SH&E half-life values are determined on an annual basis by reviewing recent past sales, aircraft availability trends, technological aspects, environmental constraints and maintenance requirements.

In the case of new aircraft, the above half-life values are automatically adjusted upwards to reflect the fact that the aircraft has the full span of maintenance overhaul intervals available. Consequently, SH&E's initial depreciation of new aircraft is considerably greater than for a used aircraft, thereby accounting for both the change in its maintenance status and its intrinsic depreciation.

BASE VALUE DEFINITION

The Base Value ("BV") is the appraiser's opinion of the underlying economic value of an asset in an open, unrestricted and stable market environment with a reasonable balance of supply and demand, and also assumes full considerations of its "highest and best use". An asset's BV is founded in the historical trend of values and in the projection of value trends and presumes an arm's-length, cash transaction between willing, able and knowledgeable parties, acting prudently, with an absence of duress and with a reasonable period of time available for marketing.

Since BV pertains to a somewhat idealized asset and market combination it may not necessarily reflect the actual value of the asset in question, but is a nominal starting value to which adjustments may be applied to determine an actual value. Since BV is related to long-term market trends, the BV definition is normally applied to analyses of historical values and projections of residual values and lease rates.

ASSUMPTIONS

SH&E used information supplied by the Client together with in-house data accumulated through other recent studies of aircraft transactions. SH&E assumed that the Subject Aircraft will meet all of the specifications and performance standards for standard 747-400F series aircraft.

SH&E's opinions are based upon historical relationships and expectations that it believes are reasonable. Some of the underlying assumptions, including those described above are detailed explicitly or implicitly elsewhere in this report, and may not materialize because of unanticipated events and circumstances. SH&E's opinions could, and would, vary materially, should any of the above assumptions prove to be inaccurate.

QUALIFICATIONS

Founded in 1963 and with offices in New York, Boston, Washington, London and Amsterdam, SH&E is the world's largest consulting firm specializing in commercial aviation. Its staff of over 90 personnel encompasses expertise in all disciplines of the industry and the firm has provided appraisal, consulting, strategic planning and technical services to airlines, leasing companies, government agencies, airframe and engine manufacturers, and financial institutions.

A related service that SH&E offers its clients is Asset Management. Over the last few years, SH&E has been the principal Asset Manager responsible for the recovery and subsequent re-marketing of a number of individual aircraft and some significant portfolios. In addition, we have been the advisors and re-marketing agents to Bank of New York, NationsCredit, NationsBank, Greyrock Capital, Potomac, Concorde, Integrated Resources and the First Fidelity Trust. In the course of those and other similar assignments we have sold, leased or parted-out over 150 aircraft, a like number of engines and approximately $30 million worth of spare parts.

In addition to the above aircraft valuations, SH&E annually values in excess of $1 billion worth of aircraft spare parts and spare engines. We have developed a statistically based methodology for the appraisal of spare parts that provides accurate valuations with known confidence levels. SH&E has also valued a number of portfolios of ground equipment, the valuations of which have been assisted by our recent acquisition, on behalf of a client, of sufficient ground equipment for the start-up of an eight aircraft airline.

This active participation in the market place provides SH&E with practical and first hand knowledge of aircraft values and lease rates. SH&E annually appraises aviation equipment worth over $10 billion. The major U.S. bond rating agencies have used SH&E's Residual Value model to validate their own depreciation schedules.

(b) Schedules.

All schedules are omitted as the required information is presented in the Registrant's consolidated financial statements or related notes or such schedules are not applicable.

ITEM 22. UNDERTAKINGS.

(1) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(2) The registrant undertakes that every prospectus: (i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of the amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by

II-10


controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection
(a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Act.

The Trustee shall initially be the registrar (the "Registrar") for the purpose of registering such Certificates of each series and transfers and exchanges of such Certificates as herein provided.

All Certificates issued upon any registration of transfer or exchange of Certificate of any series shall be valid obligations of the applicable Trust, evidencing the same interest therein, and entitled to the same benefits under this Agreement, as the Certificates of such series surrendered upon such registration of transfer or exchange.

Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office or such other office or agency, the Trustee shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates of like series, in authorized denominations of a like aggregate Fractional Undivided Interest.

At the option of a Certificateholder, Certificates may be exchanged for other Certificates of like series, in authorized denominations and of a like aggregate Fractional Undivided Interest, upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, authenticate and deliver the Certificates that the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Registrar duly executed by the Certificateholder thereof or its attorney duly authorized in writing.

No service charge shall be made to a Certificateholder for any registration of transfer or exchange of Certificates, but the Trustee shall require payment of a sum sufficient to cover any tax or similar governmental charge that may be imposed in connection with any transfer or exchange of Certificates. Certificates surrendered for registration of transfer or exchange shall be canceled and subsequently destroyed by the Trustee.

Section 3.05. Book-Entry and Definitive Certificates.

(a) The Certificates of any series may be issued in the form of one or more typewritten Certificates representing the Book-Entry Certificates of such series, to be delivered to The Depository Trust Company, the initial Clearing Agency, by, or on behalf of, the Company. In such case, the Certificates of such series delivered to The Depository Trust


-23-

Company shall initially be registered on the Register in the name of Cede & Co., the nominee of the initial Clearing Agency, and no Certificate Owner will receive a definitive certificate representing such Certificate Owner's interest in the Certificates of such series, except as provided above and in Subsection
(d) below. As to the Certificates of any series, unless and until definitive, fully registered Certificates (the "Definitive Certificates") have been issued pursuant to Subsection (d) below:

(i) the provisions of this Section 3.05 shall be in full force and effect;

(ii) the Company, the Paying Agent, the Registrar and the Trustee may deal with the Clearing Agency Participants for all purposes (including the making of distributions on the Certificates) as the authorized representatives of the Certificate Owners;

(iv) the rights of Certificate Owners shall be exercised only through the Clearing Agency and shall be limited to those established by law and agreements between such Certificate Owners and the Clearing Agency Participants; and until Definitive Certificates are issued pursuant to Subsection (d) below, the Clearing Agency will make book-entry transfers among the Clearing Agency Participants and receive and transmit distributions of principal, interest and premium, if any, on the Certificates to such Clearing Agency Participants; and

(v) whenever this Agreement requires or permits actions to be taken based upon instructions or directions of Certificateholders of such series holding Certificates of such series evidencing a specified percentage of the Fractional Undivided Interests in the related Trust, the Clearing Agency shall be deemed to represent such percentage only to the extent that it has received instructions to such effect from Clearing Agency Participants owning or representing, respectively, such required percentage of the beneficial interest in Certificates of such series and has delivered such instructions to the Trustee. The Trustee shall have no obligation to determine whether the Clearing Agency has in fact received any such instructions.

(b) Whenever notice or other communication to the Certificateholders of such series is required under this Agreement, unless and until Definitive Certificates shall have been issued pursuant to Subsection (d) below, the Trustee shall give all such notices and communications specified herein to be given to Certificateholders of such series to the Clearing Agency.


-24-

(c) Unless and until Definitive Certificates of a series are issued pursuant to Subsection (d) below, on the Record Date prior to each applicable Regular Distribution Date and Special Distribution Date, the Trustee will request from the Clearing Agency a securities position listing setting forth the names of all Clearing Agency Participants reflected on the Clearing Agency's books as holding interests in the Certificates on such Record Date.

(d) If with respect to the Certificates of any series (i) the Company advises the Trustee in writing that the Clearing Agency is no longer willing or able to discharge properly its responsibilities and the Trustee or the Company is unable to locate a qualified successor, (ii) the Company, at its option, advises the Trustee in writing that it elects to terminate the book-entry system through the Clearing Agency or (iii) after the occurrence of an Event of Default, Certificate Owners of Book-Entry Certificates of such series evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the related Trust, by Act of such Certificate Owners delivered to the Company and the Trustee, advise the Company, the Trustee and the Clearing Agency through the Clearing Agency Participants in writing that the continuation of a book-entry system through the Clearing Agency Participants is no longer in the best interests of the Certificate Owners of such series, then the Trustee shall notify all Certificate Owners of such series, through the Clearing Agency, of the occurrence of any such event and of the availability of Definitive Certificates. Upon surrender to the Trustee of all the Certificates of such series held by the Clearing Agency, accompanied by registration instructions from the Clearing Agency Participants for registration of Definitive Certificates in the names of Certificate Owners of such series, the Trustee shall issue and deliver the Definitive Certificates of such series in accordance with the instructions of the Clearing Agency. Neither the Company, the Registrar, the Paying Agent nor the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such registration instructions. Upon the issuance of Definitive Certificates of such series, the Trustee shall recognize the Person in whose name the Definitive Certificates are registered in the Register as Certificateholders hereunder. Neither the Company nor the Trustee shall be liable if the Trustee or the Company is unable to locate a qualified successor Clearing Agency.

(e) Except as otherwise provided in the related Trust Supplement, the Trustee shall enter into the applicable Letter of Representations with respect to such series of Certificates and fulfill its responsibilities thereunder.

(f) The provisions of this Section 3.05 may be made inapplicable to any series or may be amended with respect to any series in the related Trust Supplement.

Section 3.06. Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate is surrendered to the Registrar or the Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to the


-25-

Registrar and the Trustee such security, indemnity or bond, as may be required by them to save each of them harmless, then, in the absence of notice to the Registrar or the Trustee that such destroyed, lost or stolen Certificate has been acquired by a bona fide purchaser, and provided that the requirements of
Section 8-405 of the Uniform Commercial Code in effect in any applicable jurisdiction are met, the Trustee shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate or Certificates of like series, in authorized denominations and of like Fractional Undivided Interest and bearing a number not contemporaneously outstanding.

In connection with the issuance of any new Certificate under this
Section 3.06, the Trustee may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee and the Registrar) connected therewith.

Any duplicate Certificate issued pursuant to this Section 3.06 shall constitute conclusive evidence of the appropriate Fractional Undivided Interest in the related Trust, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

The provisions of this Section 3.06 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates.

Section 3.07. Persons Deemed Owners. Prior to due presentment of a Certificate for registration of transfer, the Trustee, the Registrar and any Paying Agent may treat the Person in whose name any Certificate is registered (as of the day of determination) as the owner of such Certificate for the purpose of receiving distributions pursuant to Article IV and for all other purposes whatsoever, and none of the Trustee, the Registrar or any Paying Agent shall be affected by any notice to the contrary.

Section 3.08. Cancellation. All Certificates surrendered for payment or transfer or exchange shall, if surrendered to the Trustee or any agent of the Trustee other than the Registrar, be delivered to the Registrar for cancellation and shall promptly be canceled by it. No Certificates shall be authenticated in lieu of or in exchange for any Certificates cancelled as provided in this
Section 3.08, except as expressly permitted by this Agreement. All cancelled Certificates held by the Registrar shall be destroyed and a certification of their destruction delivered to the Trustee.

Section 3.09. Limitation of Liability for Payments. All payments and distributions made to Certificateholders of any series in respect of the Certificates of such series shall be made only from the Trust Property of the related Trust and only to the extent that the


-26-

Trustee shall have sufficient income or proceeds from the Trust Property to make such payments in accordance with the terms of Article IV of this Agreement. Each Certificateholder, by its acceptance of a Certificate, agrees that it will look solely to the income and proceeds from the Trust Property of the related Trust for any payment or distribution due to such Certificateholder pursuant to the terms of this Agreement and that it will not have any recourse to the Company, the Trustee, the Loan Trustees, the Liquidity Providers, the Owner Trustees or the Owner Participants, except as otherwise expressly provided herein or in the Intercreditor Agreement.

The Company is a party to this Agreement solely for purposes of meeting the requirements of the Trust Indenture Act, and therefore shall not have any right, obligation or liability hereunder (except as otherwise expressly provided herein).

It is understood and intended that no one or more of the Certificateholders of any series shall have any right in any manner whatsoever hereunder or under the related Trust Supplement or under the Certificates of such series to (i) surrender, impair, waive, affect, disturb or prejudice any property in the Trust Property of the Trust, or the lien of any related Indenture on any property subject thereto, or the rights of the Certificateholders of such series or the holders of the Equipment Notes, (ii) obtain or seek to obtain priority over or preference with respect to any other such Certificateholder of such series or (iii) enforce any right under this Agreement, except in the manner herein provided and for the equal, ratable and common benefit of all the Certificateholders of such series subject to the provisions of this Agreement.

Section 6.08. Remedies Cumulative. Every remedy given hereunder to the Trustee or to any of the Certificateholders of any series shall not be exclusive of any other remedy or remedies, and every such remedy shall be cumulative and in addition to every other remedy given hereunder or now or hereafter given by statute, law, equity or otherwise.

Section 6.09. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Agreement, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant,


-37-

in the manner and to the extent provided in the Trust Indenture Act; provided, however, that neither this Section 6.09 nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company.

-38-

default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal, premium, if any, or interest on any Equipment Note, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith shall determine that the withholding of such notice is in the interests of the Certificateholders. For the purpose of this Section 7.02 in respect of any Trust, the term "default" means any event that is, or after notice or lapse of time or both would become, an Event of Default in respect of that Trust.

Section 315 of the Trust Indenture Act:

(a) the Trustee may rely and shall be protected in acting or refraining from acting in reliance upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(b) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Request;

(c) whenever in the administration of this Agreement or the Intercreditor Agreement, the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officer's Certificate of the Company, any related Owner Trustee or any related Loan Trustee;

(d) the Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(i) the Trustee shall not be required to expend or risk its own funds in the performance of any of its duties under this Agreement, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk is not reasonably assured to it.

Section 7.04. Not Responsible for Recitals or Issuance of Certificates. The recitals contained herein and in the Certificates of each series, except the certificates of authentication, shall not be taken as the statements of the Trustee, and the Trustee assumes no responsibility for their correctness. Subject to Section 7.15, the Trustee makes no representations as to the validity or sufficiency of this Basic Agreement, any Equipment Notes, any Intercreditor Agreement, the Certificates of any series, and Trust Supplement or any Note Documents, except that the Trustee hereby represents and warrants that this Basic Agreement has been, and each Trust Supplement, each Certificate, the Note Purchase Agreement, and each Intercreditor Agreement of, or relating to, each series will be executed and delivered by one of its officers who is duly authorized to execute and deliver such document on its behalf.

Section 7.05. May Hold Certificates. The Trustee, any Paying Agent, Registrar or any of their Affiliates or any other agent, in their respective individual or any other capacity, may become the owner or pledgee of Certificates and, subject to Sections 310(b) and 311 of the Trust Indenture Act, if applicable, may otherwise deal with the Company, any Owner Trustees or the Loan Trustees with the same rights it would have if it were not Trustee, Paying Agent, Registrar or such other agent.


-40-

Section 7.06. Money Held in Trust. Money held by the Trustee or the Paying Agent in trust under this Agreement need not be segregated from other funds except to the extent required herein or by law and neither the Trustee nor the Paying Agent shall have any liability for interest upon any such moneys except as provided for herein.

Section 7.07. Compensation and Reimbursement. The Company agrees:

(a) to pay, or cause to be paid, to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); and

(b) except as expressly provided herein or in any Trust Supplement, to reimburse, or cause to be reimbursed, the Trustee upon its request for all reasonable out-of-pocket expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Basic Agreement, any Trust Supplement or any Intercreditor Agreement (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence, willful misconduct or bad faith or as may be incurred due to the Trustee's breach of its representations and warranties set forth in Section 7.15.

The Trustee shall be entitled to reimbursement from, and shall have a lien prior to the Certificates of each series upon, all property and funds held or collected by the Trustee in its capacity as Trustee with respect to any series or the related Trust for any tax incurred without negligence, bad faith or willful misconduct, on its part, arising out of or in connection with the acceptance or administration of the Trust (other than any tax attributable to the Trustee's compensation for serving as such), including any costs and expenses incurred in contesting the imposition of any such tax. The Trustee shall notify the Company of any claim for any tax for which it may seek reimbursement. If the Trustee reimburses itself from the Trust Property of such Trust for any such tax, it will mail a brief report within 30 days setting forth the amount of such tax and the circumstances thereof to all Certificateholders of such series as their names and addresses appear in the Register.

Section 7.08. Corporate Trustee Required; Eligibility. Each Trust shall at all times have a Trustee which shall be eligible to act as a trustee under
Section 310(a) of the Trust Indenture Act and shall have a combined capital and surplus of at least $75,000,000 (or a combined capital and surplus in excess of $5,000,000 and the obligations of which, whether now in existence or hereafter incurred, are fully and unconditionally guaranteed by a corporation organized and doing business under the laws of the United States, any state or territory thereof or of the District of Columbia and having a combined capital and surplus of at least


-41-

$75,000,000). If such corporation publishes reports of conditions at least annually, pursuant to law or to the requirements of federal, state, territorial or District of Columbia supervising or examining authority, then for the purposes of this Section 7.08 the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of conditions so published.

In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 7.08 to act as Trustee of any Trust, the Trustee shall resign immediately as Trustee of such Trust in the manner and with the effect specified in Section 7.09.

Section 7.09. Resignation and Removal, Appointment of Successor. (a) No resignation or removal of the Trustee and no appointment of a successor Trustee of any Trust pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee under Section 7.10.

(b) The Trustee may resign at any time as Trustee of any or all Trusts by giving prior written notice thereof to the Company, the Authorized Agents, the related Owner Trustees and the related Loan Trustees. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Company, the related Owner Trustees and the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee.

(c) The Trustee may be removed at any time by Direction of the Certificateholders of the related series holding Certificates evidencing Fractional Undivided Interests aggregating not less than a majority in interest in such Trust delivered to the Trustee and to the Company, the related Owner Trustees and the related Loan Trustees.

(d) If at any time in respect of the Trust:

(i) the Trustee shall fail to comply with Section 310 of the Trust Indenture Act, if applicable, after written request therefor by the Company or by any Certificateholder who has been a bona fide Certificateholder for at least six months; or

(ii) the Trustee shall cease to be eligible under Section 7.08 and shall fail to resign after written request therefor by the Company or by any such Certificateholder; or

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;


-42-

then, in any case, (i) the Company may remove the Trustee or (ii) any Certificateholder of the related series who has been a bona fide Certificateholder for at least six months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee of the Trust.

(e) If a Responsible Officer of the Trustee shall obtain actual knowledge of an Avoidable Tax (as defined below) in respect of any Trust which has been or is likely to be asserted, the Trustee shall promptly notify the Company and shall, within 30 days of such notification, resign as Trustee of such Trust hereunder unless within such 30-day period the Trustee shall have received notice that the Company has agreed to pay such tax. The Company shall promptly appoint a successor Trustee of such Trust in a jurisdiction where there are no Avoidable Taxes. As used herein, an "Avoidable Tax" in respect of such Trust means a state or local tax: (i) upon (w) such Trust, (x) such Trust Property, (y) Certificateholders of such Trust or (z) the Trustee for which the Trustee is entitled to seek reimbursement from the Trust Property of such Trust, and (ii) which would be avoided if the Trustee were located in another state, or jurisdiction within a state, within the United States of America. A tax shall not be an Avoidable Tax in respect of any Trust if the Company or any Owner Trustee shall agree to pay, and shall pay, such tax.

(f) If the Trustee shall resign, be removed or become incapable of acting as Trustee of any Trust or if a vacancy shall occur in the office of the Trustee of any Trust for any cause, the Company shall promptly appoint a successor Trustee of such Trust. If, within one year after such resignation, removal or incapability, or other occurrence of such vacancy, a successor Trustee of such Trust shall be appointed by Direction of the Certificateholders of the related series holding Certificates of such series evidencing Fractional Undivided Interests aggregating not less than a majority in interest in such Trust delivered to the Company, the related Owner Trustees, the related Loan Trustee and the retiring Trustee, then the successor Trustee so appointed shall, with the approval of the Company of such appointment, which approval shall not be unreasonably withheld, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed as provided above. If no successor Trustee shall have been so appointed as provided above and accepted appointment in the manner hereinafter provided, the resigning Trustee or any Certificateholder who has been a bona fide Certificateholder of the related series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

(g) The successor Trustee shall give notice of the resignation and removal of the Trustee and appointment of the successor Trustee by mailing written notice of such event by first-class mail, postage prepaid, to the Certificateholders of the related series as their names and addresses appear in the Register. Each notice shall include the name of such successor Trustee and the address of its Corporate Trust Office.


-43-

Section 7.10. Acceptance of Appointment by Successor. Every successor Trustee appointed hereunder shall execute and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall execute and deliver an instrument transferring to such successor Trustee all such rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all Trust Property held by such retiring Trustee in respect of such Trusts hereunder, subject nevertheless to its lien, if any, provided for in Section 7.07. Upon request of any such successor Trustee, the Company, the retiring Trustee and such successor Trustee shall execute and deliver any and all instruments containing such provisions as shall be necessary or desirable to transfer and confirm to, and for more fully and certainly vesting in, such successor Trustee all such rights, powers and trusts.

If a successor Trustee is appointed with respect to one or more (but not all) Trusts, the Company, the predecessor Trustee and each successor Trustee with respect to any Trust shall execute and deliver a supplemental agreement hereto which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the predecessor Trustee with respect to the Trusts as to which the predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee, and shall add to or change any of the provisions of this Basic Agreement and the applicable Trust Supplements as shall be necessary to provide for or facilitate the administration of the Trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental agreement shall constitute such Trustees as co-Trustees of the same Trust and that each such Trustee shall be Trustee of separate Trusts.

No institution shall accept its appointment as a Trustee hereunder unless at the time of such acceptance such institution shall be qualified and eligible under this Article VII.


-44-

Section 7.11. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder; provided, however, that such corporation shall be otherwise qualified and eligible under this Article VII, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Certificates shall have been executed or authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such execution or authentication and deliver the Certificates so executed or authenticated with the same effect as if such successor Trustee had itself executed or authenticated such Certificates.

Section 7.12. Maintenance of Agencies. (a) With respect to each series of Certificates, there shall at all times be maintained an office or agency in the location set forth in Section 12.04 where Certificates of such series may be presented or surrendered for registration of transfer or for exchange, and for payment thereof, and where notices and demands, to or upon the Trustee in respect of such Certificates or this Agreement may be served; provided, however, that, if it shall be necessary that the Trustee maintain an office or agency in another location with respect to the Certificates (e.g., the Certificates of such series shall be represented by Definitive Certificates and shall be listed on a national securities exchange), the Trustee will make all reasonable efforts to establish such an office or agency. Written notice of the location of each such other office or agency and of any change of location thereof shall be given by the Trustee to the Company, any Owner Trustees, the Loan Trustees (in the case of any Owner Trustee or Loan Trustee, at its address specified in the Note Documents or such other address as may be notified to the Trustee) and the Certificateholders of such series. In the event that no such office or agency shall be maintained or no such notice of location or of change of location shall be given, presentations and demands may be made and notices may be served at the Corporate Trust Office of the Trustee.

(b) There shall at all times be a Registrar and a Paying Agent hereunder with respect to the Certificates of each series. Each such Authorized Agent shall be a bank or trust company, shall be a corporation organized and doing business under the laws of the United States or any state, with a combined capital and surplus of at least $75,000,000, or a corporation having a combined capital and surplus in excess of $5,000,000, the obligations of which are guaranteed by a corporation organized and doing business under the laws of the United States or any state, with a combined capital and surplus of at least $75,000,000, and shall be authorized under such laws to exercise corporate trust powers, subject to supervision by federal or state authorities. The Trustee shall initially be the Paying Agent and, as provided in Section 3.04, Registrar hereunder with respect to the Certificates of each series. Each Registrar


-45-

shall furnish to the Trustee, at stated intervals of not more than six months, and at such other times as the Trustee may request in writing, a copy of the Register maintained by such Registrar.

(c) Any corporation into which any Authorized Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, consolidation or conversion to which any Authorized Agent shall be a party, or any corporation succeeding to the corporate trust business of any Authorized Agent, shall be the successor of such Authorized Agent, if such successor corporation is otherwise eligible under this Section 7.12, without the execution or filing of any paper or any further act on the part of the parties hereto or such Authorized Agent or such successor corporation.

(d) Any Authorized Agent may at any time resign by giving written notice of resignation to the Trustee, the Company, any related Owner Trustees and the related Loan Trustees. The Company may, and at the request of the Trustee shall, at any time terminate the agency of any Authorized Agent by giving written notice of termination to such Authorized Agent and to the Trustee. Upon the resignation or termination of an Authorized Agent or in case at any time any such Authorized Agent shall cease to be eligible under this
Section 7.12 (when, in either case, no other Authorized Agent performing the functions of such Authorized Agent shall have been appointed), the Company shall promptly appoint one or more qualified successor Authorized Agents, reasonably satisfactory to the Trustee, to perform the functions of the Authorized Agent which has resigned or whose agency has been terminated or who shall have ceased to be eligible under this Section 7.12. The Company shall give written notice of any such appointment made by it to the Trustee, any related Owner Trustees and the related Loan Trustees; and in each case the Trustee shall mail notice of such appointment to all Certificateholders of the related series as their names and addresses appear on the Register for such series.

(e) The Company agrees to pay, or cause to be paid, from time to time to each Authorized Agent reasonable compensation for its services and to reimburse it for its reasonable expenses.

Section 7.13. Money for Certificate Payments to Be Held in Trust. All moneys deposited with any Paying Agent for the purpose of any payment on Certificates shall be deposited and held in trust for the benefit of the Certificateholders entitled to such payment, subject to the provisions of this
Section 7.13. Moneys so deposited and held in trust shall constitute a separate trust fund for the benefit of the Certificateholders with respect to which such money was deposited.

The Trustee may at any time, for the purpose of obtaining the satisfaction and discharge of this Agreement or for any other purpose, direct any Paying Agent to pay to the


-46-

Trustee all sums held in trust by such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Section 7.14. Registration of Equipment Notes in Trustee's Name. Subject to the provisions of any Intercreditor Agreement, the Trustee agrees that all Equipment Notes to be purchased by any Trust and Permitted Investments, if any, shall be issued in the name of the Trustee as Trustee for the applicable Trust or its nominee and held by the Trustee in trust for the benefit of the Certificateholders of such series, or, if not so held, the Trustee or its nominee shall be reflected as the owner of such Equipment Notes or Permitted Investments, as the case may be, in the register of the issuer of such Equipment Notes or Permitted Investments, as the case may be.

Section 7.15. Representations and Warranties of Trustee. The Trustee hereby represents and warrants that:

(c) the execution, delivery and performance by the Trustee of this Agreement, any Intercreditor Agreement and the Note Purchase Agreements (i) will not violate any provision of any United States federal law or the law of the state of the United States where it is located governing the banking and trust powers of the Trustee or any order, writ, judgment, or decree of any court, arbitrator or governmental authority applicable to the Trustee or any of its assets, (ii) will not violate any provision of the articles of association or by-laws of the Trustee, and (iii) will not violate any provision of, or constitute, with or without notice or lapse of time, a default under, or result in the creation or imposition of any lien on any properties included in the Trust Property pursuant to the provisions of any mortgage, indenture, contract, agreement or other undertaking to which it is a party, which violation, default or lien could reasonably be expected to have an adverse effect on the Trustee's performance or ability to perform its duties hereunder or thereunder or on the transactions contemplated herein or therein;


-47-

(d) the execution, delivery and performance by the Trustee of this Agreement, any Intercreditor Agreement and the Note Purchase Agreements will not require the authorization, consent, or approval of, the giving of notice to, the filing or registration with, or the taking of any other action in respect of, any governmental authority or agency of the United States or the state of the United States where it is located regulating the banking and corporate trust activities of the Trustee; and

(e) this Agreement, any Intercreditor Agreement and the Note Purchase Agreements have been duly executed and delivered by the Trustee and constitute the legal, valid and binding agreements of the Trustee, enforceable against it in accordance with their respective terms; provided, however, that enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the rights of creditors generally and (ii) general principles of equity.

As to the Certificates of any series, the Trustee, as trustee of the related grantor trust created by this Agreement, shall exclude and withhold from each distribution of principal, premium, if any, and interest and other amounts due under this Agreement or under the Certificates of such series any and all withholding taxes applicable thereto as required by law. The Trustee agrees to act as such withholding agent and, in connection therewith, whenever any present or future taxes or similar charges are required to be withheld with respect to any amounts payable in respect of the Certificates, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of the Certificateholders of such series, that it will file any necessary withholding tax returns or statements when due, and that, as promptly as possible after the payment thereof, it will deliver to each such Certificateholder of such series, appropriate documentation showing the payment thereof, together with such additional documentary evidence as such Certificateholders may reasonably request from time to time. The Trustee agrees to file any other information reports as it may be required to file under United States law.

Section 7.17. Trustee's Liens. The Trustee in its individual capacity agrees that it will, in respect of each Trust created by this Agreement, at its own cost and expense promptly take any action as may be necessary to duly discharge and satisfy in full any mortgage, pledge, lien, charge, encumbrance, security interest or claim ("Trustee's Liens") on or with respect to the Trust Property of such Trust which is attributable to the Trustee either (i) in its individual capacity and which is unrelated to the transactions contemplated by this Agreement or the related Note Documents or (ii) as Trustee hereunder or in its individual capacity and which arises out of acts or omissions which are not contemplated by this Agreement.

AMENDMENTS TO INDENTURE AND NOTE DOCUMENTS

Section 10.01. Amendments and Supplements to Indenture and Other Note Documents. In the event that the Trustee, as holder (or beneficial owner through the Subordination Agent) of any Equipment Notes (or as a prospective purchaser of any Postponed Notes) in trust for the benefit of the Certificateholders of any series or as Controlling Party under an Intercreditor Agreement, receives (directly or indirectly through the Subordination Agent) a request for a consent to any amendment, modification, waiver or supplement under any Indenture, other Note Document or any other related document, the Trustee shall forthwith send a notice of such proposed amendment, modification, waiver or supplement to each


-54-

Certificateholder of such series registered on the Register as of the date of such notice. The Trustee shall request from the Certificateholders of such series a Direction as to (a) whether or not to take or refrain from taking (or direct the Subordination Agent to take or refrain from taking) any action which a holder of (or, with respect to Postponed Notes, a prospective purchaser of) such Equipment Note has the option to direct, (b) whether or not to give or execute (or direct the Subordination Agent to give or execute) any waivers, consents, amendments, modifications or supplements as a holder of (or, with respect to Postponed Notes, a prospective purchaser of) such Equipment Note or as Controlling Party and (c) how to vote (or direct the Subordination Agent to vote) any Equipment Note (or, with respect to a Postponed Note, its commitment to acquire such Postponed Note) if a vote has been called for with respect thereto. Provided such a request for Certificateholder Direction shall have been made, in directing any action or casting any vote or giving any consent as the holder of any Equipment Note (or in directing the Subordination Agent in any of the foregoing), (i) other than as Controlling Party, the Trustee shall vote for or give consent to any such action with respect to such Equipment Note (or Postponed Note) in the same proportion as that of (A) the aggregate face amounts of all Certificates actually voted in favor of or for giving consent to such action by such Direction of Certificateholders to (B) the aggregate face amount of all Outstanding Certificates and (ii) as Controlling Party, the Trustee shall vote as directed in such Certificateholder Direction by the Certificateholders of such series evidencing a Fractional Undivided Interest aggregating not less than a majority in interest in the Trust. For purposes of the immediately preceding sentence, a Certificate shall have been "actually voted" if the Holder of such Certificate has delivered to the Trustee an instrument evidencing such Holder's consent to such Direction prior to one Business Day before the Trustee directs such action or casts such vote or gives such consent. Notwithstanding the foregoing, but subject to Section 6.04 and any Intercreditor Agreement, the Trustee may, with respect to the Certificates of any series, in its own discretion and at its own direction, consent and notify the relevant Loan Trustee of such consent (or direct the Subordination Agent to consent and notify the Loan Trustee of such consent) to any amendment, modification, waiver or supplement under any related Indenture or any other related Note Document if an Event of Default hereunder shall have occurred and be continuing or if such amendment, modification, waiver or supplement will not materially adversely affect the interests of the Certificateholders of such series.

ARTICLE XI

TERMINATION OF TRUSTS

Section 11.01. Termination of the Trusts. In respect of each Trust created by the Basic Agreement as supplemented by a related Trust Supplement, the respective obligations and responsibilities of the Company and the Trustee with respect to such Trust shall


-55-

terminate upon the distribution to all Holders of Certificates of the series of such Trust and the Trustee of all amounts required to be distributed to them pursuant to this Agreement and the disposition of all property held as part of the Trust Property of such Trust; provided, however, that in no event shall the Trust continue beyond one hundred ten (110) years following the date of the execution of the Trust Supplement with respect to such Trust (or such other final expiration date as may be specified in such Trust Supplement).

Notice of any termination of a Trust, specifying the applicable Regular Distribution Date (or the applicable Special Distribution Date, as the case may be) upon which the Certificateholders of any series may surrender their Certificates to the Trustee for payment of the final distribution and cancellation, shall be mailed promptly by the Trustee to Certificateholders of such series not earlier than 60 of days and not later than 15 days preceding such final distribution specifying (A) the Regular Distribution Date (or Special Distribution Date, as the case may be) upon which the proposed final payment of the Certificates of such series will be made upon presentation and surrender of Certificates of such series at the office or agency of the Trustee therein specified, (B) the amount of any such proposed final payment, and (C) that the Record Date otherwise applicable to such Regular Distribution Date (or Special Distribution Date, as the case may be) is not applicable, payments being made only upon presentation and surrender of the Certificates of such series at the office or agency of the Trustee therein specified. In the event that a notice of termination shall be given in connection with the termination of a Lease, the Special Distribution Date may be postponed for up to 10 Business Days. The Trustee shall give such notice to the Registrar at the time such notice is given to Certificateholders of such series. Upon presentation and surrender of the Certificates of such series in accordance with such notice, the Trustee shall cause to be distributed to Certificateholders of such series amounts distributable on such Regular Distribution Date (or Special Distribution Date, as the case may be) pursuant to Section 4.02.

In the event that all of the Certificateholders of such series shall not surrender their Certificates for cancellation within six months after the date specified in the above-mentioned written notice, the Trustee shall give a second written notice to the remaining Certificateholders of such series to surrender their Certificates for cancellation and receive the final distribution with respect thereto. No additional interest shall accrue on the Certificates of such series after any Regular Distribution Date (or Special Distribution Date, as the case may be) of such series, as specified in the first written notice. In the event that any money held by the Trustee for the payment of distributions on the Certificates of such series shall remain unclaimed for two years (or such lesser time as the Trustee shall be satisfied, after 60 days' notice from the Company, is one month prior to the escheat period provided under applicable law) after the final distribution date with respect thereto, the Trustee shall pay to each Loan Trustee the appropriate amount of money relating to such Loan Trustee and shall give


-56-

written notice thereof to the related Owner Trustees, the Owner Participants and the Company.

ARTICLE XII

[THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT

OF 1933, AS AMENDED (THE "SECURITIES ACT") OR ANY STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2),
(3) OR (7) UNDER THE SECURITIES ACT) (AN "INSTITUTIONAL ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS CERTIFICATE IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT; (2) AGREES THAT IT WILL NOT, PRIOR TO EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE CERTIFICATES UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION) RESELL OR OTHERWISE TRANSFER THIS CERTIFICATE EXCEPT (A) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (B) INSIDE THE UNITED STATES TO AN INSTITUTIONAL ACCREDITED INVESTOR ACQUIRING $100,000 OR MORE AGGREGATE PRINCIPAL AMOUNT OF SUCH CERTIFICATE, THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS CERTIFICATE (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE TRUSTEE), (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (D) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), (E) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER), OR (F) TO ATLAS OR ANY SUBSIDIARY THEREOF; (3) PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(E) ABOVE), IT WILL FURNISH TO THE TRUSTEE SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A


-21-

TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND (4) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS CERTIFICATE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS CERTIFICATE PRIOR TO THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE CERTIFICATES UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE.

THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE CERTIFICATES PURSUANT TO CLAUSE 2(E) ABOVE OR UPON ANY TRANSFER OF THE CERTIFICATES UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION). AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION", "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT. THE PASS THROUGH TRUST AGREEMENT CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS CERTIFICATE IN VIOLATION OF THE FOREGOING RESTRICTIONS.]1

(b) Each Global Certificate shall also bear the following legend on the face thereof:

OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.


(a) Not to be included on the face of the Permanent Offshore Global Certificate.

TRANSFERS OF THIS GLOBAL CERTIFICATE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL CERTIFICATE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN SECTIONS 8.04 AND 8.05 OF THE TRUST SUPPLEMENT TO THE PASS THROUGH TRUST AGREEMENT REFERRED TO HEREIN.

Section 8.03. TRANSFER AND EXCHANGE. An Applicable Certificateholder may transfer an Applicable Certificate by written application to the Registrar stating the name of the proposed transferee and otherwise complying with the terms of this Agreement, including providing a written certificate or other evidence of compliance with any restrictions on transfer. No such transfer shall be effected until, and such transferee shall succeed to the rights of an Applicable Certificateholder only upon, final acceptance and registration of the transfer by the Registrar in the Register. Prior to the registration of any transfer by an Applicable Certificateholder as provided herein, the Trustee shall treat the person in whose name the Applicable Certificate is registered as the owner thereof for all purposes, and the Trustee shall not be affected by notice to the contrary. Furthermore, DTC shall, by acceptance of a Global Certificate, agree that transfers of beneficial interests in such Global Certificate may be effected only through a book-entry system maintained by DTC (or its agent), and that ownership of a beneficial interest in the Certificate shall be required to be reflected in a book entry. When Applicable Certificates are presented to the Registrar with a request to register the transfer or to exchange them for an equal face amount of Applicable Certificates of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met. To permit registrations of transfers and exchanges in accordance with the terms, conditions and restrictions hereof, the Trustee shall execute and authenticate Applicable Certificates at the Registrar's request.

Section 8.04. BOOK-ENTRY PROVISIONS FOR U.S. GLOBAL CERTIFICATE AND OFFSHORE GLOBAL CERTIFICATES. (a) Members of, or participants in, DTC ("Agent Members") shall have no rights under this Agreement with respect to any Global Certificate held on their behalf by DTC, or the Trustee as its custodian, and DTC may be treated by the Trustee and any agent of the Trustee as the absolute owner of such Global Certificate for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Trustee or any agent of the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or shall impair, as between DTC and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Applicable Certificate. Upon the issuance of any Global Certificate, the Registrar or its duly appointed agent shall record a nominee of DTC as the registered holder of such Global Certificate.

(b) Transfers of any Global Certificate shall be limited to transfers of such Global Certificate or Offshore Global Certificate in whole, but not in part, to nominees of DTC, its successor or such successor's nominees. Beneficial interests in the U.S. Global Certificate and any Offshore Global Certificate may be transferred in accordance with the rules and procedures of DTC and the provisions of Section 8.05. Beneficial interests in the U.S. Global Certificate or an Offshore Global Certificate shall be delivered to all beneficial owners in the form of U.S. Physical Certificates or Offshore Physical Certificates, as the case may be, if (i) DTC notifies the Trustee that it is unwilling or unable to continue as depositary for the U.S. Global Certificate or such Offshore Global Certificate, as the case may be, and a successor depositary is not appointed by the Trustee within 90 days of such notice or (ii) an Event of Default has occurred and Applicable Certificateholders with fractional undivided interests aggregating not less than a majority in interest in the Applicable Trust advise the Trustee, the Company and DTC through Agent Members in writing that the continuation of a book-entry system through DTC (or a successor thereto) is no longer in the Applicable Certificateholders' best interests.

Notwithstanding the foregoing, nothing herein shall prevent the Trustee or any agent of the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or shall impair, as between DTC and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Applicable Certificate. Upon the issuance of any Global Certificate, the Registrar or its duly appointed agent shall record a nominee of DTC as the registered holder of such Global Certificate.

(b) Transfers of any Global Certificate shall be limited to transfers of such Global Certificate or Offshore Global Certificate in whole, but not in part, to nominees of DTC, its successor or such successor's nominees. Beneficial interests in the U.S. Global Certificate and any Offshore Global Certificate may be transferred in accordance with the rules and procedures of DTC and the provisions of Section 8.05. Beneficial interests in the U.S. Global Certificate or an Offshore Global Certificate shall be delivered to all beneficial owners in the form of U.S. Physical Certificates or Offshore Physical Certificates, as the case may be, if (i) DTC notifies the Trustee that it is unwilling or unable to continue as depositary for the U.S. Global Certificate or such Offshore Global Certificate, as the case may be, and a successor depositary is not appointed by the Trustee within 90 days of such notice or (ii) an Event of Default has occurred and Applicable Certificateholders with fractional undivided interests aggregating not less than a majority in interest in the Applicable Trust advise the Trustee, the Company and DTC through Agent Members in writing that the continuation of a book-entry system through DTC (or a successor thereto) is no longer in the Applicable Certificateholders' best interests.

(c) Any beneficial interest in one of the Global Certificates that is transferred to a Person who takes delivery in the form of an interest in the other Global Certificate will, upon such transfer, cease to be an interest in such Global Certificate and become an interest in the other Global Certificate and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Certificate for as long as it remains such an interest.

(d) In connection with the transfer of the entire U.S. Global Certificate or an entire Offshore Global Certificate to the beneficial owners thereof pursuant to paragraph (b) of this Section 8.04, such U.S. Global Certificate or Offshore Global Certificate, as the case may be, shall be deemed to be surrendered to the Trustee for cancellation, and the Trustee shall execute, authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in such U.S. Global Certificate or Offshore Global Certificate,


-23-

as the case may be, an equal aggregate principal amount of U.S. Physical Certificates or Offshore Physical Certificates, as the case may be, of authorized denominations.

(e) Any U.S. Physical Certificate delivered in exchange for an interest in the U.S. Global Certificate pursuant to paragraph (b) of this
Section 8.04 shall, except as otherwise provided by paragraph (f) of Section 8.05, bear the Private Placement Legend.

(f) Any Offshore Physical Certificate delivered in exchange for an interest in an Offshore Global Certificate pursuant to paragraph (b) of this Section shall, except as otherwise provided by paragraph (f) of Section 8.05, bear the applicable legend regarding transfer restrictions set forth in
Section 8.02(a).

(g) The registered holder of the U.S. Global Certificate or any Offshore Global Certificate may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Agreement or the Applicable Certificates.

Section 8.05. SPECIAL TRANSFER PROVISIONS. Unless and until

(a) TRANSFERS TO NON-QIB INSTITUTIONAL ACCREDITED INVESTORS. The following provisions shall apply with respect to the registration of any proposed transfer of an Applicable Certificate to any Institutional Accredited Investor which is not a QIB (excluding transfers to or by Non-U.S. Persons):

(ii) If the proposed transferor is an Agent Member holding a beneficial interest in the U.S. Global Certificate, upon receipt by the Registrar of (x) the documents, if any, required by paragraph (i) and (y) instructions given in accordance with DTC's and the Registrar's procedures, the Registrar shall reflect on its books and records the date of the transfer and a decrease in the principal amount of such U.S. Global Certificate in an amount equal to the principal amount of the beneficial interest in such U.S. Global Certificate to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver to the transferor or at its direction, one or more U.S. Physical Certificates of like tenor and amount.

(b) TRANSFERS TO QIBS. The following provisions shall apply with respect to the registration of any proposed transfer of an Initial Certificate to a QIB (excluding Non-U.S. Persons):

(i) If the Initial Certificate to be transferred consists of U.S. Physical Certificates or an interest in any Temporary Offshore Global Certificate, the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the


-24-

box provided for on the form of Initial Certificate stating, or has otherwise advised the Trustee and the Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Initial Certificate stating, or has otherwise advised the Trustee and the Registrar in writing, that it is purchasing the Initial Certificate for its own account or an account with respect to which it exercises sole investment discretion and that it, or the Person on whose behalf it is acting with respect to any such account, is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Trust and/or the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A.

(ii) Upon receipt by the Registrar of the documents referred to in clause (i) above and instructions given in accordance with DTC's and the Registrar's procedures therefor, the Registrar shall reflect on its books and records the date of such transfer and an increase in the principal amount of the U.S. Global Certificate in an amount equal to the principal amount of the U.S. Physical Certificates or interests in the Temporary Offshore Global Certificate, as the case may be, being transferred, and the Trustee shall cancel such Physical Certificates or decrease the amount of such Temporary Offshore Global Certificate so transferred.

(c) TRANSFERS OF INTERESTS IN THE PERMANENT OFFSHORE GLOBAL CERTIFICATE OR OFFSHORE PHYSICAL CERTIFICATES. The Registrar shall register any transfer of interests in the Permanent Offshore Global Certificate or Offshore Physical Certificates without requiring any additional certification.

(d) TRANSFERS TO NON-U.S. PERSONS AT ANY TIME. The following provisions shall apply with respect to any registration of any transfer of an Initial Certificate to a Non-U.S. Person:

(i) Prior to the Offshore Certificates Exchange Date, the Registrar shall register any proposed transfer of an Initial Certificate to a Non-U.S. Person upon receipt of a certificate substantially in the form set forth as Exhibit C hereto from the proposed transferor.

(ii) On and after the Offshore Certificates Exchange Date, the Registrar shall register any proposed transfer to any Non-U.S. Person if the Initial Certificate to be transferred is a U.S. Physical Certificate or an interest in the U.S. Global Certificate, upon receipt of a certificate substantially in the form of Exhibit C from the proposed transferor. The Registrar shall promptly send a copy of such certificate to the Company.

(iii) (A) Upon receipt by the Registrar of (x) the documents, if any, required by paragraph (ii) and (y) instructions in accordance with DTC's and the Registrar's procedures, the Registrar shall reflect on its books and records the date of such transfer and a decrease in the principal amount of such U.S. Global Certificate in an amount equal to the principal amount of the beneficial interest in such U.S. Global Certificate to be transferred, and (B) upon receipt by the Registrar of instructions given in accordance


-25-

with DTC's and the Registrar's procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Offshore Global Certificate in an amount equal to the principal amount of the U.S. Physical Certificate or the U.S. Global Certificate, as the case may be, to be transferred, and the Trustee shall cancel the Physical Certificate, if any, so transferred or decrease the amount of such U.S. Global Certificate.

(e) PRIVATE PLACEMENT LEGEND. Upon the transfer, exchange or replacement of Applicable Certificates not bearing the Private Placement Legend, the Registrar shall deliver Applicable Certificates that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Applicable Certificates bearing the Private Placement Legend, the Registrar shall deliver only Applicable Certificates that bear the Private Placement Legend unless either (i) the circumstances contemplated by paragraph (a)(i)(x) or (e)(ii) of this Section 8.05 exist or (ii) there is delivered to the Registrar an Opinion of Counsel to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

(f) GENERAL. By its acceptance of any Applicable Certificate bearing the Private Placement Legend, each Holder of such an Applicable Certificate acknowledges the restrictions on transfer of such Applicable Certificate set forth in this Agreement and agrees that it will transfer such Applicable Certificate only as provided in this Agreement. The Registrar shall not register a transfer of any Applicable Certificate unless such transfer complies with the restrictions on transfer of such Applicable Certificate set forth in this Agreement. In connection with any transfer of Applicable Certificates, each Applicable Certificateholder agrees by its acceptance of the Applicable Certificates to furnish the Registrar or the Trustee such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act; provided that the Registrar shall not be required to determine the sufficiency of any such certifications, legal opinions or other information.

Until such time as no Applicable Certificates remain Outstanding, the Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 8.04 or this Section 8.05. The Trustee, if not the Registrar at such time, shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

Section 8.04. BOOK-ENTRY PROVISIONS FOR U.S. GLOBAL CERTIFICATE AND OFFSHORE GLOBAL CERTIFICATES. (a) Members of, or participants in, DTC ("Agent Members") shall have no rights under this Agreement with respect to any Global Certificate held on their behalf by DTC, or the Trustee as its custodian, and DTC may be treated by the Trustee and any agent of the Trustee as the absolute owner of such Global Certificate for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Trustee or any agent of the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or shall impair, as between DTC and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Applicable Certificate. Upon the issuance of any Global Certificate, the Registrar or its duly appointed agent shall record a nominee of DTC as the registered holder of such Global Certificate.

(b) Transfers of any Global Certificate shall be limited to transfers of such Global Certificate or Offshore Global Certificate in whole, but not in part, to nominees of DTC, its successor or such successor's nominees. Beneficial interests in the U.S. Global Certificate and any Offshore Global Certificate may be transferred in accordance with the rules and procedures of DTC and the provisions of Section 8.05. Beneficial interests in the U.S. Global Certificate or an Offshore Global Certificate shall be delivered to all beneficial owners in the form of U.S. Physical Certificates or Offshore Physical Certificates, as the case may be, if (i) DTC notifies the Trustee that it is unwilling or unable to continue as depositary for the U.S. Global Certificate or such Offshore Global Certificate, as the case may be, and a successor depositary is not appointed by the Trustee within 90 days of such notice or (ii) an Event of Default has occurred and Applicable Certificateholders with fractional undivided interests aggregating not less than a majority in interest in the Applicable Trust advise the Trustee, the Company and DTC through Agent Members in writing that the continuation of a book-entry system through DTC (or a successor thereto) is no longer in the Applicable Certificateholders' best interests.

(c) Any beneficial interest in one of the Global Certificates that is transferred to a Person who takes delivery in the form of an interest in the other Global Certificate will, upon such transfer, cease to be an interest in such Global Certificate and become an interest in the other Global Certificate and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Certificate for as long as it remains such an interest.

(d) In connection with the transfer of the entire U.S. Global Certificate or an entire Offshore Global Certificate to the beneficial owners thereof pursuant to paragraph (b) of this Section 8.04, such U.S. Global Certificate or Offshore Global Certificate, as the case may be, shall be deemed to be surrendered to the Trustee for cancellation, and the Trustee shall execute, authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in such U.S. Global Certificate or Offshore Global Certificate, as the case may be, an equal aggregate principal amount of U.S. Physical Certificates or Offshore Physical Certificates, as the case may be, of authorized denominations.

(e) Any U.S. Physical Certificate delivered in exchange for an interest in the U.S. Global Certificate pursuant to paragraph (b) of this Section 8.04 shall, except as otherwise provided by paragraph (f) of Section 8.05, bear the Private Placement Legend.


-23-

(f) Any Offshore Physical Certificate delivered in exchange for an interest in an Offshore Global Certificate pursuant to paragraph (b) of this
Section shall, except as otherwise provided by paragraph (f) of Section 8.05, bear the applicable legend regarding transfer restrictions set forth in Section 8.02(a).

(g) The registered holder of the U.S. Global Certificate or any Offshore Global Certificate may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Agreement or the Applicable Certificates.

Section 8.05. SPECIAL TRANSFER PROVISIONS. Unless and until (i) an Initial Certificate is sold under an effective Shelf Registration Statement, or

(ii) If the proposed transferor is an Agent Member holding a beneficial interest in the U.S. Global Certificate, upon receipt by the Registrar of (x) the documents, if any, required by paragraph (i) and (y) instructions given in accordance with DTC's and the Registrar's procedures, the Registrar shall reflect on its books and records the date of the transfer and a decrease in the principal amount of such U.S. Global Certificate in an amount equal to the principal amount of the beneficial interest in such U.S. Global Certificate to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver to the transferor or at its direction, one or more U.S. Physical Certificates of like tenor and amount.

(b) TRANSFERS TO QIBS. The following provisions shall apply with respect to the registration of any proposed transfer of an Initial Certificate to a QIB (excluding Non-U.S. Persons):

(i) If the Initial Certificate to be transferred consists of U.S. Physical Certificates or an interest in any Temporary Offshore Global Certificate, the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Initial Certificate stating, or has otherwise advised the Trustee and the Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Initial Certificate stating, or has otherwise advised the Trustee and the Registrar in writing, that it is purchasing the Initial Certificate for its own account or an account with respect to which it exercises sole investment discretion and that it, or the Person on whose behalf it is acting with respect to any such


-24-

account, is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Trust and/or the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A.

(ii) Upon receipt by the Registrar of the documents referred to in clause (i) above and instructions given in accordance with DTC's and the Registrar's procedures therefor, the Registrar shall reflect on its books and records the date of such transfer and an increase in the principal amount of the U.S. Global Certificate in an amount equal to the principal amount of the U.S. Physical Certificates or interests in the Temporary Offshore Global Certificate, as the case may be, being transferred, and the Trustee shall cancel such Physical Certificates or decrease the amount of such Temporary Offshore Global Certificate so transferred.

(c) TRANSFERS OF INTERESTS IN THE PERMANENT OFFSHORE GLOBAL CERTIFICATE OR OFFSHORE PHYSICAL CERTIFICATES. The Registrar shall register any transfer of interests in the Permanent Offshore Global Certificate or Offshore Physical Certificates without requiring any additional certification.

(d) TRANSFERS TO NON-U.S. PERSONS AT ANY TIME. The following provisions shall apply with respect to any registration of any transfer of an Initial Certificate to a Non-U.S. Person:

(i) Prior to the Offshore Certificates Exchange Date, the Registrar shall register any proposed transfer of an Initial Certificate to a Non-U.S. Person upon receipt of a certificate substantially in the form set forth as Exhibit C hereto from the proposed transferor.

(ii) On and after the Offshore Certificates Exchange Date, the Registrar shall register any proposed transfer to any Non-U.S. Person if the Initial Certificate to be transferred is a U.S. Physical Certificate or an interest in the U.S. Global Certificate, upon receipt of a certificate substantially in the form of Exhibit C from the proposed transferor. The Registrar shall promptly send a copy of such certificate to the Company.

(iii) (A) Upon receipt by the Registrar of (x) the documents, if any, required by paragraph (ii) and (y) instructions in accordance with DTC's and the Registrar's procedures, the Registrar shall reflect on its books and records the date of such transfer and a decrease in the principal amount of such U.S. Global Certificate in an amount equal to the principal amount of the beneficial interest in such U.S. Global Certificate to be transferred, and (B) upon receipt by the Registrar of instructions given in accordance with DTC's and the Registrar's procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Offshore Global Certificate in an amount equal to the principal amount of the U.S. Physical Certificate or the U.S. Global Certificate, as the case may be, to be transferred, and the Trustee shall cancel the Physical Certificate, if any, so transferred or decrease the amount of such U.S. Global Certificate.


-25-

(e) PRIVATE PLACEMENT LEGEND. Upon the transfer, exchange or replacement of Applicable Certificates not bearing the Private Placement Legend, the Registrar shall deliver Applicable Certificates that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Applicable Certificates bearing the Private Placement Legend, the Registrar shall deliver only Applicable Certificates that bear the Private Placement Legend unless either (i) the circumstances contemplated by paragraph (a)(i)(x) or (e)(ii) of this Section 8.05 exist or (ii) there is delivered to the Registrar an Opinion of Counsel to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

(f) GENERAL. By its acceptance of any Applicable Certificate bearing the Private Placement Legend, each Holder of such an Applicable Certificate acknowledges the restrictions on transfer of such Applicable Certificate set forth in this Agreement and agrees that it will transfer such Applicable Certificate only as provided in this Agreement. The Registrar shall not register a transfer of any Applicable Certificate unless such transfer complies with the restrictions on transfer of such Applicable Certificate set forth in this Agreement. In connection with any transfer of Applicable Certificates, each Applicable Certificateholder agrees by its acceptance of the Applicable Certificates to furnish the Registrar or the Trustee such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act; provided that the Registrar shall not be required to determine the sufficiency of any such certifications, legal opinions or other information.

Until such time as no Applicable Certificates remain Outstanding, the Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 8.04 or this Section 8.05. The Trustee, if not the Registrar at such time, shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

(f) Upon the making of any Advance requested pursuant to a Notice of Borrowing, in accordance with the Borrower's payment instructions, the Liquidity Provider shall be fully discharged of its obligation hereunder with respect to such Notice of Borrowing, and the Liquidity Provider shall not thereafter be obligated to make any further Advances hereunder in respect of such Notice of Borrowing to the Borrower or to any other Person. If the Liquidity Provider makes an Advance requested pursuant to a Notice of Borrowing before 12:00 noon (New York City time) on the second Business Day after the date of payment specified in said Section 2.02(e), the Liquidity Provider shall have fully discharged its obligations hereunder with respect to such Advance and an event of default and shall not have occurred hereunder. Following the making of any Advance pursuant to Section 2.02(b), (c) or (d) hereof to fund the Class A Cash Collateral Account, the Liquidity Provider shall have no interest in or rights to the Class A Cash Collateral Account, such Advance or any other amounts from time to time on deposit in the Class A Cash Collateral Account; provided that the foregoing shall not affect or impair the obligations of the Subordination Agent to make the distributions contemplated by Section 3.6(e) or
(f) of the Intercreditor Agreement. By paying to the Borrower proceeds of Advances requested by the Borrower in accordance with the provisions of this Agreement, the Liquidity Provider makes no representation as to, and assumes no responsibility for, the correctness or sufficiency for any purpose of the amount of the Advances so made and requested.

Section 2.03. Fees. The Borrower agrees to pay to the Liquidity Provider the fees set forth in the WestLB Fee Letter.

Section 2.04. Reduction or Termination of the Maximum Commitment. (a) Automatic Reduction. Promptly following each date on which the Required Amount is reduced as a result of a reduction in the Pool Balance of the Class A Certificates or otherwise, the Maximum Commitment shall automatically be reduced to an amount equal to such reduced Required Amount (as calculated by the Borrower). The Borrower shall give notice of any such automatic reduction of the Maximum Commitment to the Liquidity Provider within two Business Days thereof. The failure by the Borrower to furnish any such notice shall not affect such automatic reduction of the Maximum Commitment.

(b) Termination. Upon the making of any Provider Advance or Final Advance hereunder or the occurrence of the Termination Date, the obligation of the Liquidity Provider to make further Advances hereunder shall automatically and irrevocably terminate, and the Borrower shall not be entitled to request any further Borrowing hereunder.

Section 2.05. Repayments of Interest Advances or the Final Advance. Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby agrees, without notice of an Advance or demand for repayment from the Liquidity Provider (which notice and demand are hereby waived by the Borrower), to pay, or to cause to be paid, to the Liquidity Provider on each date on which the Liquidity Provider shall make an Interest Advance or the Final Advance, an amount equal to (a) the amount of such Advance (any such Advance, until repaid, is referred to herein as an "Unpaid Advance"), plus (b) interest on the amount of each such Unpaid Advance as provided in Section 3.07 hereof; provided that if
(i) the Liquidity Provider shall make a Provider Advance at any time after making one or more Interest Advances which shall not have been repaid in

9

accordance with this Section 2.05 or (ii) this Liquidity Facility shall become a Downgraded Facility or Non-Extended Facility at any time when unreimbursed Interest Advances have reduced the Maximum Commitment to zero, then such Interest Advances shall cease to constitute Unpaid Advances and shall be deemed to have been changed into an Applied Downgrade Advance or an Applied Non-Extension Advance, as the case may be, for all purposes of this Agreement (including, without limitation, for the purpose of determining when such Interest Advance is required to be repaid to the Liquidity Provider in accordance with Section 2.06 and for the purposes of Section 2.06(b)). The Borrower and the Liquidity Provider agree that the repayment in full of each Interest Advance and Final Advance on the date such Advance is made is intended to be a contemporaneous exchange for new value given to the Borrower by the Liquidity Provider.

Section 2.06. Repayments of Provider Advances. (a) Amounts advanced hereunder in respect of a Provider Advance shall be deposited in the Class A Cash Collateral Account, invested and withdrawn from the Class A Cash Collateral Account as set forth in Sections 3.6(c), (d) and (f) of the Intercreditor Agreement. The Borrower agrees to pay to the Liquidity Provider, on each Regular Distribution Date, commencing on the first Regular Distribution Date after the making of a Provider Advance, interest on the principal amount of any such Provider Advance as provided in Section 3.07; provided, however, that amounts in respect of a Provider Advance withdrawn from the Class A Cash Collateral Account for the purpose of paying interest on the Class A Certificates in accordance with Section 3.6(f) of the Intercreditor Agreement (the amount of any such withdrawal being (y) in the case of a Downgrade Advance, an "Applied Downgrade Advance" and (z) in the case of a Non-Extension Advance, an "Applied Non-Extension Advance" and, together with an Applied Downgrade Advance, an "Applied Provider Advance") shall thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon; provided further, however, that if, following the making of a Provider Advance, the Liquidity Provider delivers a Termination Notice to the Borrower pursuant to
Section 6.01 hereof, such Provider Advance shall thereafter be treated as a Final Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon. Subject to Sections 2.07 and 2.09 hereof, immediately upon the withdrawal of any amounts from the Class A Cash Collateral Account on account of a reduction in the Required Amount, the Borrower shall repay to the Liquidity Provider a portion of the Provider Advances in a principal amount equal to such reduction, plus interest on the principal amount prepaid as provided in Section 3.07 hereof.

(b) At any time when an Applied Provider Advance (or any portion thereof) is outstanding, upon the deposit in the Class A Cash Collateral Account of any amount pursuant to clause "third" of Section 2.4(b) of the Intercreditor Agreement, clause "third" of Section 3.2 of the Intercreditor Agreement or clause "fourth" of Section 3.3 of the Intercreditor Agreement (any such amount being a "Replenishment Amount") for the purpose of replenishing or increasing the balance thereof up to the Required Amount at such time, (i) the aggregate outstanding principal amount of all Applied Provider Advances (and of each Provider Advance treated as an Interest Advance for purposes of determining the Applicable Liquidity Rate for interest payable thereon) shall be automatically reduced by the amount of such Replenishment Amount and (ii) the

10

aggregate outstanding principal amount of all Unapplied Provider Advances shall be automatically increased by the amount of such Replenishment Amount.

(c) Upon the provision of a Replacement Liquidity Facility in replacement of this Agreement in accordance with Section 3.6(e) of the Intercreditor Agreement, amounts remaining on deposit in the Class A Cash Collateral Account after giving effect to any Applied Provider Advance on the date of such replacement shall be reimbursed to the Liquidity Provider, but only to the extent such amounts are necessary to repay in full to the Liquidity Provider all amounts owing to it hereunder.

Section 2.07. Payments to the Liquidity Provider Under the Intercreditor Agreement. In order to provide for payment or repayment to the Liquidity Provider of any amounts hereunder, the Intercreditor Agreement provides that amounts available and referred to in Articles II and III of the Intercreditor Agreement, to the extent payable to the Liquidity Provider pursuant to the terms of the Intercreditor Agreement (including, without limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid to the Liquidity Provider in accordance with the terms thereof. Amounts so paid to the Liquidity Provider shall be applied by the Liquidity Provider to Liquidity Obligations then due and payable in accordance with the Intercreditor Agreement or, if not provided for in the Intercreditor Agreement, then in such manner as the Liquidity Provider shall deem appropriate.

Section 2.08. Book Entries. The Liquidity Provider shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower resulting from Advances made from time to time and the amounts of principal and interest payable hereunder and paid from time to time in respect thereof; provided, however, that the failure by the Liquidity Provider to maintain such account or accounts shall not affect the obligations of the Borrower in respect of Advances.

Section 2.09. Payments from Available Funds Only. All payments to be made by the Borrower under this Agreement shall be made only from the amounts that constitute Scheduled Payments, Special Payments or payments under
Section 8.1 or 9.1, as the case may be, of the Participation Agreements and
Section 6 of the Note Purchase Agreement and only to the extent that the Borrower shall have sufficient income or proceeds therefrom to enable the Borrower to make payments in accordance with the terms hereof after giving effect to the priority of payments provisions set forth in the Intercreditor Agreement. The Liquidity Provider agrees that it will look solely to such amounts to the extent available for distribution to it as provided in the Intercreditor Agreement and this Agreement and that the Borrower, in its individual capacity, is not personally liable to it for any amounts payable or liability under this Agreement except as expressly provided in this Agreement, the Intercreditor Agreement or any Participation Agreement. Amounts on deposit in the Class A Cash Collateral Account shall be available to the Borrower to make payments under this Agreement only to the extent and for the purposes expressly contemplated in Section 3.6(f) of the Intercreditor Agreement.

Section 2.10. Extension of the Expiry Date: Non-Extension Advance. No earlier than the 60th day and no later than the 40th day prior to the then effective Expiry Date (unless

11

such Expiry Date is on or after the date that is 15 days after the Final Maturity Date for the Class A Certificates), the Borrower shall request that the Liquidity Provider extend the Expiry Date for a period of 364 days after the then effective Expiry Date (unless the obligations of the Liquidity Provider are earlier terminated in accordance with the terms hereof). The Liquidity Provider shall advise the Borrower, no earlier than 40 days and no later than 25 days prior to the then effective Expiry Date, whether, in its sole discretion, it agrees to so extend the Expiry Date. If the Liquidity Provider advises the Borrower on or before the 25th day prior to the Expiry Date then in effect that such Expiry Date shall not be so extended, or fails to irrevocably and unconditionally advise the Borrower on or before the 25th day prior to the Expiry Date then in effect that such Expiry Date shall be so extended (and, in each case, if the Liquidity Provider shall not have been replaced in accordance with Section 3.6(e) of the Intercreditor Agreement), the Borrower shall be entitled on and after such 25th day (but prior to the then effective Expiry Date) to request a Non-Extension Advance in accordance with Section 2.02(b) hereof and Section 3.6(d) of the Intercreditor Agreement.

ARTICLE III

OBLIGATIONS OF THE BORROWER

Section 3.01. Increased Costs. The Borrower shall pay to the Liquidity Provider from time to time such amounts as may be necessary to compensate the Liquidity Provider for any increased costs incurred by the Liquidity Provider which are attributable to its making or maintaining any LIBOR Advances hereunder or its obligation to make any such Advances hereunder, or any reduction in any amount receivable by the Liquidity Provider under this Agreement or the Intercreditor Agreement in respect of any such Advances or such obligation (such increases in costs and reductions in amounts receivable being herein called "Additional Costs"), resulting from any change after the date of this Agreement in U.S. federal, state, municipal, or foreign laws or regulations (including Regulation D of the Board of Governors of the Federal Reserve System), or the adoption or making after the date of this Agreement of any interpretations, directives, or requirements applying to a class of banks including the Liquidity Provider under any U.S. federal, state, municipal, or any foreign laws or regulations (whether or not having the force of law) by any court, central bank or monetary authority charged with the interpretation or administration thereof (a " Regulatory Change"), which: (1) changes the basis of taxation of any amounts payable to the Liquidity Provider under this Agreement in respect of any such Advances (other than Excluded Taxes); or (2) imposes or modifies any reserve, special deposit, compulsory loan or similar requirements relating to any extensions of credit or other assets of, or any deposits with other liabilities of, the Liquidity Provider (including any such Advances or any deposits referred to in the definition of LIBOR Rate or related definitions). The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

12

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.01 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.01 of the effect of any Regulatory Change on its costs of making or maintaining Advances or on amounts receivable by it in respect of Advances, and of the additional amounts required to compensate the Liquidity Provider in respect of any Additional Costs, shall be prima facie evidence of the amount owed under this Section.

Section 3.02. Capital Adequacy. If (1) the adoption, after the date hereof, of any applicable governmental law, rule or regulation regarding capital adequacy, (2) any change, after the date hereof, in the interpretation or administration of any such law, rule or regulation by any central bank or other governmental authority charged with the interpretation or administration thereof or (3) compliance by the Liquidity Provider or any corporation controlling the Liquidity Provider with any applicable guideline or request of general applicability, issued after the date hereof, by any central bank or other governmental authority (whether or not having the force of law) that constitutes a change of the nature described in clause (2), has the effect of requiring an increase in the amount of capital required to be maintained by the Liquidity Provider or any corporation controlling the Liquidity Provider, and such increase is based upon the Liquidity Provider's obligations hereunder and other similar obligations, the Borrower shall pay to the Liquidity Provider from time to time such additional amount or amounts as are necessary to compensate the Liquidity Provider for such portion of such increase as shall be reasonably allocable to the Liquidity Provider's obligations to the Borrower hereunder. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise materially disadvantageous to the Liquidity Provider.

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.02 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.02 of the effect of any increase in the amount of capital required to be maintained by the Liquidity Provider and of the amount allocable to the Liquidity Provider's obligations to the Borrower hereunder shall be prima facie evidence of the amounts owed under this Section.

Section 3.03. Payments Free of Deductions. All payments made by the Borrower under this Agreement shall be made free and clear of, and without reduction for or on account of, any present or future stamp or other taxes, levies, imposts, duties, charges, fees, deductions, withholdings, restrictions or conditions of any nature whatsoever now or hereafter imposed, levied, collected, withheld or assessed, excluding Excluded Taxes (such non-excluded taxes being referred to herein, collectively, as "Non-Excluded Taxes" and, individually, as a "Non-

13

Excluded Tax"). If any Non-Excluded Taxes are required to be withheld from any amounts payable to the Liquidity Provider under this Agreement, the amounts so payable to the Liquidity Provider shall be increased to the extent necessary to yield to the Liquidity Provider (after payment of all Non-Excluded Taxes) interest or any other such amounts payable under this Agreement at the rates or in the amounts specified in this Agreement. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider. From time to time upon the reasonable request of the Borrower, the Liquidity Provider agrees to provide to the Borrower two original Internal Revenue Service Forms W-8 BEN or W-8 ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that the Liquidity Provider is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement.

(b) All payments (including, without limitation, Advances) made by the Liquidity Provider under this Agreement shall be made free and clear of, and without reduction for or on account of, any Taxes. If any Taxes are required to be withheld or deducted from any amounts payable to the Borrower under this Agreement, the Liquidity Provider shall (i) within the time prescribed therefor by applicable law pay to the appropriate governmental or taxing authority the full amount of any such Taxes (and any additional Taxes in respect of the payment required under clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) pay to the Borrower an additional amount which (after deduction of all such Taxes) will be sufficient to yield to the Borrower the full amount which would have been received by it had no such withholding or deduction been made. Within 30 days after the date of each payment hereunder, the Liquidity Provider shall furnish to the Borrower the original or a certified copy of (or other documentary evidence of) the payment of the Taxes applicable to such payment.

Section 3.04. Payments. The Borrower shall make or cause to be made each payment to the Liquidity Provider under this Agreement so as to cause the same to be received by the Liquidity Provider not later than 1:00 P.M. (New York City time) on the day when due. The Borrower shall make all such payments in lawful money of the United States of America, to the Liquidity Provider in immediately available funds, by wire transfer to The Chase Manhattan Bank, ABA No. 021-000-021, for account of Westdeutsche Landesbank Girozentrale, New York Branch, Account No. 920-1-060663, Reference: Atlas Air, Inc., 2000-1A.

Section 3.05. Computations. All computations of interest based on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the LIBOR Rate shall be made on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable.

Section 3.06. Payment on Non-Business Days. Whenever any payment to be made hereunder shall be stated to be due on a day other than a Business Day, such payment shall

14

be made on the next succeeding Business Day and no additional interest shall be due as a result (and if so made, shall be deemed to have been made when due). If any payment in respect of interest on an Advance is so deferred to the next succeeding Business Day, such deferral shall not delay the commencement of the next Interest Period for such Advance (if such Advance is a LIBOR Advance) or reduce the number of days for which interest will be payable on such Advance on the next interest payment date for such Advance.

Section 3.07. Interest. (a) Subject to Section 2.09, the Borrower shall pay, or shall cause to be paid, without duplication, interest on
(i) the unpaid principal amount of each Advance from and including the date of such Advance (or, in the case of an Applied Provider Advance, from and including the date on which the amount thereof was withdrawn from the Class A Cash Collateral Account to pay interest on the Class A Certificates) to but excluding the date such principal amount shall be paid in full (or, in the case of an Applied Provider Advance, the date on which the Class A Cash Collateral Account is fully replenished in respect of such Advance) and (ii) any other amount due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by law, installments of interest on Advances or any such other amount) which is not paid when due (whether at stated maturity, by acceleration or otherwise) from and including the due date thereof to but excluding the date such amount is paid in full, in each such case, at a fluctuating interest rate per annum for each day equal to the Applicable Liquidity Rate (as defined below) for such Advance or such other amount as in effect for such day, but in no event at a rate per annum greater than the maximum rate permitted by applicable law; provided, however, that, if at any time the otherwise applicable interest rate as set forth in this Section 3.07 shall exceed the maximum rate permitted by applicable law, then any subsequent reduction in such interest rate will not reduce the rate of interest payable pursuant to this Section 3.07 below the maximum rate permitted by applicable law until the total amount of interest accrued equals the amount of interest that would have accrued if such otherwise applicable interest rate as set forth in this Section 3.07 had at all times been in effect.

(b) Each Advance (other than any Unapplied Provider Advance) will be either a Base Rate Advance or a LIBOR Advance as provided in this Section. Each such Advance will be a Base Rate Advance for the period from the date of its borrowing to (but excluding) the third Business Day following the Liquidity Provider's receipt of the Notice of Borrowing for such Advance. Thereafter, such Advance shall be a LIBOR Advance. Each Applied Provider Advance and a Final Advance that is deemed to have been made without delivery of a Notice of Borrowing pursuant to Section 2.06 shall be a LIBOR Advance from the day such Advance is made; provided that the Borrower (at the direction of the Controlling Party, so long as the Liquidity Provider is not the Controlling Party) may (x) convert the Final Advance into a Base Rate Advance on the last day of an Interest Period for such Advance by giving the Liquidity Provider no less than four Business Days' prior written notice of such election or (y) elect to maintain the Final Advance as a Base Rate Advance by not requesting a conversion of the Final Advance to a LIBOR Advance under Clause (5) of the applicable Notice of Borrowing (or, if such Final Advance is deemed to have been made without delivery of a Notice of Borrowing pursuant to Section 2.06, by requesting, prior to 11:00 AM on the first Business Day immediately following the Borrower's receipt of the applicable Termination Notice, that such Final Advance not be converted from a Base Rate Advance to a LIBOR Advance).

15

(c) Each LIBOR Advance shall bear interest during each Interest Period at a rate per annum equal to the LIBOR Rate for such Interest Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on the last day of such Interest Period and, in the event of the payment of principal of such LIBOR Advance on a day other than such last day, on the date of such payment (to the extent of interest accrued on the amount of principal repaid).

(d) Each Base Rate Advance shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin for such Base Rate Advance, payable in arrears on each Regular Distribution Date and, in the event of the payment of principal of such Base Rate Advance on a day other than a Regular Distribution Date, on the date of such payment (to the extent of interest accrued on the amount of principal repaid).

(e) Each Unapplied Provider Advance shall bear interest in an amount equal to the Investment Earnings on amounts on deposit in the Class A Cash Collateral Account.

(f) Each amount not paid when due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by applicable law, installments of interest on Advances but excluding Advances) shall bear interest at a rate per annum equal to the Base Rate plus 3.25% until paid.

(g) Each change in the Base Rate shall become effective immediately. The rates of interest specified in this Section 3.07 with respect to any Advance or other amount shall be referred to as the "Applicable Liquidity Rate".

Section 3.08. Replacement of Borrower. From time to time and subject to the successor Borrower's meeting the eligibility requirements set forth in Section 6.9 of the Intercreditor Agreement applicable to the Subordination Agent, upon the effective date and time specified in a written and completed Notice of Replacement Subordination Agent in substantially the form of Annex VI attached hereto (a "Notice of Replacement Subordination Agent") delivered to the Liquidity Provider by the then Borrower, the successor Borrower designated therein shall be substituted for as the Borrower for all purposes hereunder.

Section 3.09. Funding Loss Indemnification. The Borrower shall pay to the Liquidity Provider, upon the request of the Liquidity Provider, such amount or amounts as shall be sufficient (in the reasonable opinion of the Liquidity Provider) to compensate it for any loss, cost, or expense incurred by reason of the liquidation or redeployment of deposits or other funds acquired by the Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss of anticipated profits) incurred as a result of:

(1) Any repayment of a LIBOR Advance on a date other than the last day of the Interest Period for such Advance; or

(2) Any failure by the Borrower to borrow a LIBOR Advance on the date for borrowing specified in the relevant notice under Section 2.02.

16

Section 3.10. Illegality. Notwithstanding any other provision in this Agreement, if any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Liquidity Provider (or its Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for the Liquidity Provider (or its Lending Office) to maintain or fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity Provider, the outstanding principal amount of the LIBOR Advances shall be converted to Base Rate Advances (a) immediately upon demand of the Liquidity Provider, if such change or compliance with such request, in the judgment of the Liquidity Provider, requires immediate repayment; or (b) at the expiration of the last Interest Period to expire before the effective date of any such change or request.

A copy of all notices delivered hereunder to either party shall in addition be delivered to each of the parties to the Participation Agreements at their respective addresses set forth therein.

Section 7.03. No Waiver: Remedies. No failure on the part of the Liquidity Provider to exercise, and no delay in exercising, any right under this Agreement shall operate as a waiver thereof; nor shall any single or partial exercise of any right under this Agreement preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

Section 7.04. Further Assurances. The Borrower agrees to do such further acts and things and to execute and deliver to the Liquidity Provider such additional assignments, agreements, powers and instruments as the Liquidity Provider may reasonably require or deem advisable to carry into effect the purposes of this Agreement and the other Operative Agreements or to better assure and confirm unto the Liquidity Provider its rights, powers and remedies hereunder and under the other Operative Agreements.

Section 7.05. Indemnification; Survival of Certain Provisions. The Liquidity Provider shall be indemnified hereunder to the extent and in the manner described in Section 9.1 of the Leased Aircraft Participation Agreement,
Section 8.1 of the Owned Aircraft Participation Agreement and Section 6 of the Note Purchase Agreement. In addition, the Borrower agrees to indemnify, protect, defend and hold harmless the Liquidity Provider from, against and in respect of, and shall pay on demand, all Expenses of any kind or nature whatsoever (other than any Expenses of the nature described in Sections 3.01, 3.02 or 7.07 hereof or in the WestLB Fee Letter (regardless of whether indemnified against pursuant to said Sections or in such WestLB Fee

21

Letter)), that may be imposed, incurred by or asserted against any Liquidity Indemnitee, in any way relating to, resulting from, or arising out of or in connection with any action, suit or proceeding by any third party against such Liquidity Indemnitee and relating to this Agreement, the WestLB Fee Letter, the Intercreditor Agreement or any Financing Agreement; provided, however, that the Borrower shall not be required to indemnify, protect, defend and hold harmless any Liquidity Indemnitee in respect of any Expense of such Liquidity Indemnitee to the extent such Expense is (i) attributable to the gross negligence or willful misconduct of such Liquidity Indemnitee or any other Liquidity Indemnitee, (ii) ordinary and usual operating overhead expense, or (iii) attributable to the failure by such Liquidity Indemnitee or any other Liquidity Indemnitee to perform or observe any agreement, covenant or condition on its part to be performed or observed in this Agreement, the Intercreditor Agreement, the WestLB Fee Letter, the Tax Letter or any other Operative Agreement to which it is a party. The indemnities contained in Section 9.1 or 8.1, as the case may be, of the Participation Agreements, and the provisions of Sections 3.01, 3.02, 3.03, 3.09, 7.05 and 7.07 hereof, shall survive the termination of this Agreement.

Section 7.06. Liability of the Liquidity Provider. (a) Neither the Liquidity Provider nor any of its officers, employees, directors or affiliates shall be liable or responsible for: (i) the use which may be made of the Advances or any acts or omissions of the Borrower or any beneficiary or transferee in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; or (iii) the making of Advances by the Liquidity Provider against delivery of a Notice of Borrowing and other documents which do not comply with the terms hereof; provided, however, that the Borrower shall have a claim against the Liquidity Provider, and the Liquidity Provider shall be liable to the Borrower, to the extent of any damages suffered by the Borrower which were the result of (A) the Liquidity Provider's willful misconduct or negligence in determining whether documents presented hereunder comply with the terms hereof, or (B) any breach by the Liquidity Provider of any of the terms of this Agreement, including, but not limited to, the Liquidity Provider's failure to make lawful payment hereunder after the delivery to it by the Borrower of a Notice of Borrowing strictly complying with the terms and conditions hereof.

(b) Neither the Liquidity Provider nor any of its officers, employees, director or affiliates shall be liable or responsible in any respect for (i) any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with this Agreement or any Notice of Borrowing delivered hereunder, or (ii) any action, inaction or omission which may be taken by it in good faith, absent willful misconduct or negligence (in which event the extent of the Liquidity Provider's potential liability to the Borrower shall be limited as set forth in the immediately preceding paragraph), in connection with this Agreement or any Notice of Borrowing.

Section 7.07. Costs, Expenses and Taxes. The Borrower agrees to pay, or cause to be paid (A) on the Effective Date and on such later date or dates on which the Liquidity Provider shall make demand, all reasonable out-of-pocket costs and expenses (including, without limitation, the reasonable fees and expenses of outside counsel for the Liquidity Provider) of the Liquidity Provider in connection with the preparation, negotiation, execution, delivery, filing and recording of this Agreement, any other Operative Agreement and any other documents which may be delivered in connection with this Agreement and (B) on demand, all reasonable costs and expenses

22

(including reasonable counsel fees and expenses) of the Liquidity Provider in connection with (i) the enforcement of this Agreement or any other Operative Agreement, (ii) the modification or amendment of, or supplement to, this Agreement or any other Operative Agreement or such other documents which may be delivered in connection herewith or therewith (whether or not the same shall become effective) or (iii) any action or proceeding relating to any order, injunction, or other process or decree restraining or seeking to restrain the Liquidity Provider from paying any amount under this Agreement, the Intercreditor Agreement or any other Operative Agreement or otherwise affecting the application of funds in the Class A Cash Collateral Account. In addition, the Borrower shall pay any and all recording, stamp and other similar taxes and fees payable or determined to be payable in connection with the execution, delivery, filing and recording of this Agreement, any other Operative Agreement and such other documents, and agrees to save the Liquidity Provider harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such taxes or fees.

Section 7.08. Binding Effect; Participations.

(a) This Agreement shall be binding upon and inure to the benefit of the Borrower and the Liquidity Provider and their respective successors and assigns, except that neither the Liquidity Provider (except as otherwise provided in this Section 7.08) nor (except as contemplated by Section 3.08) the Borrower shall have the right to assign its rights or obligations hereunder or any interest herein without the prior written consent of the other party, subject to the requirements of Section 7.08(b). The Liquidity Provider may grant participations herein or in any of its rights hereunder (including, without limitation, funded participations and participations in rights to receive interest payments hereunder) and under the other Operative Agreements to such Persons (not including Atlas or any affiliate of Atlas) as the Liquidity Provider may in its sole discretion select, subject to the requirements of
Section 7.08(b). No such participation by the Liquidity Provider, however, will relieve the Liquidity Provider of its obligations hereunder. In connection with any participation or any proposed participation, the Liquidity Provider may disclose to the participant or the proposed participant any information that the Borrower is required to deliver or to disclose to the Liquidity Provider pursuant to this Agreement. The Borrower acknowledges and agrees that the Liquidity Provider's source of funds may derive in part from its participants. Accordingly, references in this Agreement and the other Operative Agreements to determinations, reserve and capital adequacy requirements, increased costs, reduced receipts, additional amounts due pursuant to Section 3.03(a) and the like as they pertain to the Liquidity Provider shall be deemed also to include those of each of its participants (subject, in each case, to the maximum amount that would have been incurred by or attributable to the Liquidity Provider directly if the Liquidity Provider, rather than the participant, had held the interest participated).

(b) If, pursuant to subsection (a) above, the Liquidity Provider sells any participation in this Agreement to any bank or other entity (each, a "Transferee"), then, concurrently with the effectiveness of such participation, the Transferee shall (i) represent to the Liquidity Provider (for the benefit of the Liquidity Provider and the Borrower) either (A) that it is incorporated under the laws of the United States or a state thereof or (B) that under applicable law and treaties, no taxes will be required to be withheld with respect to any payments to be made to such Transferee in respect of this Agreement, (ii) furnish to the Liquidity Provider and the

23

Borrower either (x) a statement that it is incorporated under the laws of the United States or a state thereof or (y) if it is not so incorporated, two copies of a properly completed United States Internal Revenue Service Form W-8 ECI or Form W-8 BEN, as appropriate, or other applicable form, certificate or document prescribed by the Internal Revenue Service certifying, in each case, such Transferee's entitlement to a complete exemption from United States federal withholding tax in respect to any and all payments to be made hereunder, and
(iii) agree (for the benefit of the Liquidity Provider and the Borrower) to provide the Liquidity Provider and the Borrower a new Form W-8 ECI or Form W-8 BEN, as appropriate, (A) on or before the date that any such form expires or becomes obsolete or (B) after the occurrence of any event requiring a change in the most recent form previously delivered by it and prior to the immediately following due date of any payment by the Borrower hereunder, certifying in the case of a Form W-8 BEN or Form W-8 ECI that such Transferee is entitled to a complete exemption from United States federal withholding tax on payments under this Agreement. Unless the Borrower has received forms or other documents reasonably satisfactory to it (and required by applicable law) indicating that payments hereunder are not subject to United States federal withholding tax, the Borrower will withhold taxes as required by law from such payments at the applicable statutory rate.

(c) Notwithstanding the other provisions of this Section 7.08, the Liquidity Provider may assign and pledge all or any portion of the Advances owing to it to any Federal Reserve Bank or the United States Treasury as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank, provided that any payment in respect of such assigned Advances made by the Borrower to the Liquidity Provider in accordance with the terms of this Agreement shall satisfy the Borrower's obligations hereunder in respect of such assigned Advance to the extent of such payment. No such assignment shall release the Liquidity Provider from its obligations hereunder.

Section 7.09. Severability. Any provision of this Agreement which is prohibited, unenforceable or not authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition, unenforceability or nonauthorization without invalidating the remaining provisions hereof or affecting the validity, enforceability or legality of such provision in any other jurisdiction.

Section 7.10. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

Section 7.11. Submission to Jurisdiction; Waiver of Jury Trial; Waiver of Immunity. (a) Each of the parties hereto hereby irrevocably and unconditionally:

(i) submits for itself and its property in any legal action or proceeding relating to this Agreement or any other Operative Agreement, or for recognition and enforcement of any judgment in respect hereof or thereof, to the nonexclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and the appellate courts from any thereof;

24

(ii) consents that any such action or proceeding may be brought in such courts, and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(iii) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form and mail), postage prepaid, to each party hereto at its address set forth in Section 7.02 hereof, or at such other address of which the Liquidity Provider shall have been notified pursuant thereto; and

(iv) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction.

(b) THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING ESTABLISHED, including, without limitation, contract claims, tort claims, breach of duty claims and all other common law and statutory claims. The Borrower and the Liquidity Provider each warrant and represent that it has reviewed this waiver with its legal counsel, and that it knowingly and voluntarily waives its jury trial rights following consultation with such legal counsel. THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

(c) The Liquidity Provider hereby waives any immunity it may have from the jurisdiction of the courts of the United States or of any State and waives any immunity any of its properties located in the United States may have from attachment or execution upon a judgement entered by any such court under the United States Foreign Sovereign Immunities Act of 1976 or any similar successor legislation.

Section 7.12. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto on separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 7.13. Entirety. This Agreement, the Intercreditor Agreement and the other Operative Agreements to which the Liquidity Provider is a party constitute the entire agreement of the parties hereto with respect to the subject matter hereof and supersedes all prior understandings and agreements of such parties.

25

Section 7.14. Headings. Section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

Section 7.15. LIQUIDITY PROVIDER'S OBLIGATION TO MAKE ADVANCES. EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE OBLIGATIONS OF THE LIQUIDITY PROVIDER TO MAKE ADVANCES HEREUNDER, AND THE BORROWER'S RIGHTS TO DELIVER NOTICES OF BORROWING REQUESTING THE MAKING OF ADVANCES HEREUNDER, SHALL BE UNCONDITIONAL AND IRREVOCABLE, AND SHALL BE PAID OR PERFORMED, IN EACH CASE STRICTLY IN ACCORDANCE WITH THE TERMS OF THIS AGREEMENT.

Annex III attached hereto, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Commitment at such time, and shall be used to fund the Class B Cash Collateral Account in accordance with said Section 3.6(c) and Section 3.6(f) of the Intercreditor Agreement.

(d) A Final Advance shall be made in a single Borrowing upon the receipt by the Borrower of a Termination Notice from the Liquidity Provider pursuant to Section 6.01 hereof by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex IV attached hereto, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Commitment at such time, and shall be used to fund the Class B Cash Collateral Account (in accordance with Section 3.6(i) of the Intercreditor Agreement) and Section 3.6(f) of the Intercreditor Agreement.

If a Notice of Borrowing is delivered by the Borrower in respect of any Borrowing no later than 1:00 PM (New York City time) on a Business Day, upon satisfaction of the conditions precedent set forth in Section 4.02 with respect to a requested Borrowing, the Liquidity Provider shall make available to the Borrower, in accordance with its payment instructions, the amount of such Borrowing in U.S. dollars and immediately available funds, before 4:00 PM (New York City time) on the day of receipt of such Notice of Borrowing or on such later Business Day specified in such Notice of Borrowing. If a Notice of Borrowing is delivered by the Borrower in respect of any Borrowing after 1:00 PM (New York City time) on a Business Day, upon satisfaction of the conditions precedent set forth in Section 4.02 with respect to a requested Borrowing, the Liquidity Provider shall make available to the Borrower, in accordance with its payment instructions, the amount of such Borrowing in U.S. dollars and immediately available funds, before 4:00 PM (New York City time) on the first Business Day next following the day of receipt of such Notice of Borrowing or on such later Business Day specified by the Borrower in such Notice of Borrowing. Payments of proceeds of a Borrowing shall be made by wire transfer of immediately available funds to the Borrower in accordance with such wire transfer instructions as the Borrower shall furnish from time to time to the Liquidity Provider for such purpose. Each Notice of Borrowing shall be irrevocable and binding on the Borrower.

(f) Upon the making of any Advance requested pursuant to a Notice of Borrowing, in accordance with the Borrower's payment instructions, the Liquidity Provider shall be fully discharged of its obligation hereunder with respect to such Notice of Borrowing, and the Liquidity Provider shall not thereafter be obligated to make any further Advances hereunder in respect of such Notice of Borrowing to the Borrower or to any other Person. If the Liquidity Provider makes an Advance requested pursuant to a Notice of Borrowing before 12:00 Noon (New York City time) on the second Business Day after the date of payment specified in said Section 2.02(e), the Liquidity Provider shall have fully discharged its obligations hereunder with respect to such Advance and an event of default shall not have occurred hereunder. Following the making of any Advance pursuant to Section 2.02(b), (c) or (d) hereof to fund the Class B Cash Collateral Account, the Liquidity Provider shall have no interest in or rights to the Class B Cash Collateral Account, such Advance or any other amounts from time to time on deposit in the


Class B Cash Collateral Account; provided that the foregoing shall not affect or impair the obligations of the Subordination Agent to make the distributions contemplated by Section 3.6(e) or (f) of the Intercreditor Agreement. By paying to the Borrower proceeds of Advances requested by the Borrower in accordance with the provisions of this Agreement, the Liquidity Provider makes no representation as to, and assumes no responsibility for, the correctness or sufficiency for any purpose of the amount of the Advances so made and requested.

Section 2.03. Fees. The Borrower agrees to pay to the Liquidity Provider the fees set forth in the MSCS Fee Letter.

Section 2.04. Reduction or Termination of the Maximum Commitment.

(a) Automatic Reduction. Promptly following each date on which the Required Amount is reduced as a result of a reduction in the Pool Balance of the Class B Certificates or otherwise, the Maximum Commitment shall automatically be reduced to an amount equal to such reduced Required Amount (as calculated by the Borrower). The Borrower shall give notice of any such automatic reduction of the Maximum Commitment to the Liquidity Provider within two Business Days thereof. The failure by the Borrower to furnish any such notice shall not affect such automatic reduction of the Maximum Commitment.

(b) Termination. Upon the making of any Provider Advance or Final Advance hereunder or the occurrence of the Termination Date, the obligation of the Liquidity Provider to make further Advances hereunder shall automatically and irrevocably terminate, and the Borrower shall not be entitled to request any further Borrowing hereunder.

Section 2.05. Repayments of Interest Advances or the Final Advance. Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby agrees, without notice of an Advance or demand for repayment from the Liquidity Provider (which notice and demand are hereby waived by the Borrower), to pay, or to cause to be paid, to the Liquidity Provider on each date on which the Liquidity Provider shall make an Interest Advance or the Final Advance, an amount equal to (a) the amount of such Advance (any such Advance, until repaid, is referred to herein as an "Unpaid Advance"), plus (b) interest on the amount of each such Unpaid Advance as provided in Section 3.07 hereof; provided that if
(i) the Liquidity Provider shall make a Provider Advance at any time after making one or more Interest Advances which shall not have been repaid in accordance with this Section 2.05 or (ii) this Liquidity Facility shall become a Downgraded Facility or Non-Extended Facility at any time when unreimbursed Interest Advances have reduced the Maximum Commitment to zero, then such Interest Advances shall cease to constitute Unpaid Advances and shall be deemed to have been changed into an Applied Downgrade Advance or Applied Non-Extension Advance for all purposes of this Agreement (including, without limitation, for the purpose of determining when such Interest Advance is required to be repaid to the Liquidity Provider in accordance with Section 2.06 and for the purposes of Section 2.06(b)). The Borrower and the Liquidity Provider agree that the repayment in full of each Interest Advance and Final Advance on the date such Advance is made is intended to be a contemporaneous exchange for new value given to the Borrower by the Liquidity Provider.


Section 2.06. Repayments of Provider Advances. (a) Amounts advanced hereunder in respect of a Provider Advance shall be deposited in the Class B Cash Collateral Account, invested and withdrawn from the Class B Cash Collateral Account as set forth in Sections 3.6(c), (d) and (f) of the Intercreditor Agreement. The Borrower agrees to pay to the Liquidity Provider, on each Regular Distribution Date, commencing on the first Regular Distribution Date after the making of a Provider Advance, interest on the principal amount of any such Provider Advance as provided in Section 3.07; provided, however, that amounts in respect of a Provider Advance withdrawn from the Class B Cash Collateral Account for the purpose of paying interest on the Class B Certificates in accordance with Section 3.6(f) of the Intercreditor Agreement (the amount of any such withdrawal being (x) in the case of a Downgrade Advance, an "Applied Downgrade Advance" and (y) in the case of a Non-Extension Advance, an "Applied Non-Extension Advance" and, together with an Applied Downgrade Advance, an "Applied Provider Advance") shall thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon; provided further, however, that if, following the making of a Provider Advance, the Liquidity Provider delivers a Termination Notice to the Borrower pursuant to
Section 6.01 hereof, such Provider Advance shall thereafter be treated as a Final Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon. Subject to Sections 2.07 and 2.09 hereof, immediately upon the withdrawal of any amounts from the Class B Cash Collateral Account on account of a reduction in the Required Amount, the Borrower shall repay to the Liquidity Provider a portion of the Provider Advances in a principal amount equal to such reduction, plus interest on the principal amount prepaid as provided in Section 3.07 hereof.

(b) At any time when an Applied Provider Advance (or any portion thereof) is outstanding, upon the deposit in the Class B Cash Collateral Account of any amount pursuant to clause "third" of Section 2.4(b) of the Intercreditor Agreement, clause "third" of Section 3.2 of the Intercreditor Agreement or clause "fourth" of Section 3.3 of the Intercreditor Agreement (any such amount being a "Replenishment Amount") for the purpose of replenishing or increasing the balance thereof up to the Required Amount at such time, (i) the aggregate outstanding principal amount of all Applied Provider Advances (and of Provider Advances treated as an Interest Advance for purposes of determining the Applicable Liquidity Rate for interest payable thereon) shall be automatically reduced by the amount of such Replenishment Amount and (ii) the aggregate outstanding principal amount of all Unapplied Provider Advances shall be automatically increased by the amount of such Replenishment Amount.

(c) Upon the provision of a Replacement Liquidity Facility in replacement of this Agreement in accordance with Section 3.6(e) of the Intercreditor Agreement, amounts remaining on deposit in the Class B Cash Collateral Account after giving effect to any Applied Provider Advance on the date of such replacement shall be reimbursed to the Liquidity Provider, but only to the extent such amounts are necessary to repay in full to the Liquidity Provider all amounts owing to it hereunder.

Section 2.07. Payments to the Liquidity Provider Under the Intercreditor Agreement. In order to provide for payment or repayment to the Liquidity Provider of any


amounts hereunder, the Intercreditor Agreement provides that amounts available and referred to in Articles II and III of the Intercreditor Agreement, to the extent payable to the Liquidity Provider pursuant to the terms of the Intercreditor Agreement (including, without limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid to the Liquidity Provider in accordance with the terms thereof. Amounts so paid to the Liquidity Provider shall be applied by the Liquidity Provider to Liquidity Obligations then due and payable in accordance with the Intercreditor Agreement or, if not provided for in the Intercreditor Agreement, then in such manner as the Liquidity Provider shall deem appropriate.

Section 2.08. Book Entries. The Liquidity Provider shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower resulting from Advances made from time to time and the amounts of principal and interest payable hereunder and paid from time to time in respect thereof; provided, however, that the failure by the Liquidity Provider to maintain such account or accounts shall not affect the obligations of the Borrower in respect of Advances.

Section 2.09. Payments from Available Funds Only. All payments to be made by the Borrower under this Agreement shall be made only from the amounts that constitute Scheduled Payments, Special Payments or payments under
Section 8.1 or 9.1, as the case may be, of the Participation Agreements and
Section 6 of the Note Purchase Agreement and only to the extent that the Borrower shall have sufficient income or proceeds therefrom to enable the Borrower to make payments in accordance with the terms hereof after giving effect to the priority of payments provisions set forth in the Intercreditor Agreement. The Liquidity Provider agrees that it will look solely to such amounts to the extent available for distribution to it as provided in the Intercreditor Agreement and this Agreement and that the Borrower, in its individual capacity, is not personally liable to it for any amounts payable or liability under this Agreement except as expressly provided in this Agreement, the Intercreditor Agreement or any Participation Agreement. Amounts on deposit in the Class B Cash Collateral Account shall be available to the Borrower to make payments under this Agreement only to the extent and for the purposes expressly contemplated in Section 3.6(f) of the Intercreditor Agreement.

Section 2.10. Extension of the Expiry Date; Non-Extension Advance. The Expiry Date shall be automatically extended, effective on the 25th day prior to each Expiry Date (unless such Expiry Date is on or after the date that is 15 days after the Final Legal Distribution Date for the Class B Certificates), for a period of 364 days after such Expiry Date (unless the obligations of the Liquidity Provider are earlier terminated in accordance with the terms hereof), without the necessity of any act on the part of the Borrower or the Liquidity Provider, unless the Liquidity Provider shall advise the Borrower prior to such 25th day that it does not agree to such extension of such Expiry Date, in which event (and if the Liquidity Provider shall not have been replaced in accordance with Section 3.6(e) of the Intercreditor Agreement), the Borrower shall be entitled on and after such 25th day (but prior to such Expiry Date) to request a Non-Extension Advance in accordance with Section 2.02(b) hereof and Section 3.6(d) of the Intercreditor Agreement.


ARTICLE III

OBLIGATIONS OF THE BORROWER

Section 3.01. Increased Costs. The Borrower shall pay to the Liquidity Provider from time to time such amounts as may be necessary to compensate the Liquidity Provider for any increased costs incurred by the Liquidity Provider which are attributable to its making or maintaining any LIBOR Advances hereunder or its obligation to make any such Advances hereunder, or any reduction in any amount receivable by the Liquidity Provider under this Agreement or the Intercreditor Agreement in respect of any such Advances or such obligation (such increases in costs and reductions in amounts receivable being herein called "Additional Costs"), resulting from any change after the date of this Agreement in U.S. federal, state, municipal, or foreign laws or regulations ("Regulatory Change") which changes the basis of taxation of any amounts payable to the Liquidity Provider under this Agreement in respect of any such Advances (other than Excluded Taxes). The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.01 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.01 of the effect of any Regulatory Change on its costs of making or maintaining Advances or on amounts receivable by it in respect of Advances, and of the additional amounts required to compensate the Liquidity Provider in respect of any Additional Costs, shall be prima facie evidence of the amount owed under this Section.

Section 3.02. Capital Adequacy. If (1) the adoption, after the date hereof, of any applicable governmental law, rule or regulation regarding capital adequacy, (2) any change, after the date hereof, in the interpretation or administration of any such law, rule or regulation by any central bank or other governmental authority charged with the interpretation or administration thereof or (3) compliance by the Liquidity Provider or any corporation controlling the Liquidity Provider with any applicable guideline or request of general applicability, issued after the date hereof, by any central bank or other governmental authority (whether or not having the force of law) that constitutes a change of the nature described in clause (2), has the effect of requiring an increase in the amount of capital required to be maintained by the Liquidity Provider or any corporation controlling the Liquidity Provider, and such increase is based upon the Liquidity Provider's obligations hereunder and other similar obligations, the Borrower shall pay to the Liquidity Provider from time to time such additional amount or amounts as are necessary to compensate the Liquidity Provider for such portion of such increase as shall be reasonably allocable to the Liquidity Provider's obligations to the Borrower hereunder. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid


the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise materially disadvantageous to the Liquidity Provider.

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.02 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.02 of the effect of any increase in the amount of capital required to be maintained by the Liquidity Provider and of the amount allocable to the Liquidity Provider's obligations to the Borrower hereunder shall be prima facie evidence of the amounts owed under this Section.

Section 3.03. Payments Free of Deductions. (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without reduction for or on account of, any present or future stamp or other taxes, levies, imposts, duties, charges, fees, deductions, withholdings, restrictions or conditions of any nature whatsoever now or hereafter imposed, levied, collected, withheld or assessed, excluding Excluded Taxes (such non-excluded taxes being referred to herein, collectively, as "Non-Excluded Taxes" and, individually, as a "Non-Excluded Tax"). If any Non-Excluded Taxes are required to be withheld from any amounts payable to the Liquidity Provider under this Agreement, the amounts so payable to the Liquidity Provider shall be increased to the extent necessary to yield to the Liquidity Provider (after payment of all Non-Excluded Taxes) interest or any other such amounts payable under this Agreement at the rates or in the amounts specified in this Agreement. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider. From time to time upon the reasonable request of the Borrower, the Liquidity Provider agrees to provide to the Borrower two original Internal Revenue Service Forms W-8 BEN or W-8 ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that the Liquidity Provider is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement.

(b) All payments (including, without limitation, Advances) made by the Liquidity Provider under this Agreement shall be made free and clear of, and without reduction for or on account of, any Taxes. If any Taxes are required to be withheld or deducted from any amounts payable to the Borrower under this Agreement, the Liquidity Provider shall (i) within the time prescribed therefor by applicable law pay to the appropriate governmental or taxing authority the full amount of any such Taxes (and any additional Taxes in respect of the payment required under clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) pay to the Borrower an additional amount which (after deduction of all such Taxes) will be sufficient to yield to the Borrower the full amount which would have been received by it had no such withholding or deduction been made. Within 30 days after the date of each payment hereunder, the Liquidity


Provider shall furnish to the Borrower the original or a certified copy of (or other documentary evidence of) the payment of the Taxes applicable to such payment.

Section 3.04. Payments. The Borrower shall make or cause to be made each payment to the Liquidity Provider under this Agreement so as to cause the same to be received by the Liquidity Provider not later than 1:00 P.M. (New York City time) on the day when due. The Borrower shall make all such payments in lawful money of the United States of America, to the Liquidity Provider in immediately available funds, by wire transfer to Citibank, N.A., New York, NY, ABA# 021000089, Account Name: Morgan Stanley Capital Services, Inc., Account # 4072-4601, Reference: Atlas Air, Inc., 2000-1B.

Section 3.05. Computations. All computations of interest based on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the LIBOR Rate shall be made on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable.

Section 3.06. Payment on Non-Business Days. Whenever any payment to be made hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and no additional interest shall be due as a result (and if so made, shall be deemed to have been made when due). If any payment in respect of interest on an Advance is so deferred to the next succeeding Business Day, such deferral shall not delay the commencement of the next Interest Period for such Advance (if such Advance is a LIBOR Advance) or reduce the number of days for which interest will be payable on such Advance on the next interest payment date for such Advance.

Section 3.07. Interest. (a) Subject to Section 2.09, the Borrower shall pay, or shall cause to be paid, without duplication, interest on
(i) the unpaid principal amount of each Advance from and including the date of such Advance (or, in the case of an Applied Provider Advance, from and including the date on which the amount thereof was withdrawn from the Class B Cash Collateral Account to pay interest on the Class B Certificates) to but excluding the date such principal amount shall be paid in full (or, in the case of an Applied Provider Advance, the date on which the Class B Cash Collateral Account is fully replenished in respect of such Advance) and (ii) any other amount due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by law, installments of interest on Advances or any such other amount) which is not paid when due (whether at stated maturity, by acceleration or otherwise) from and including the due date thereof to but excluding the date such amount is paid in full, in each such case, at a fluctuating interest rate per annum for each day equal to the Applicable Liquidity Rate (as defined below) for such Advance or such other amount as in effect for such day, but in no event at a rate per annum greater than the maximum rate permitted by applicable law; provided, however, that, if at any time the otherwise applicable interest rate as set forth in this Section 3.07 shall exceed the maximum rate permitted by applicable law, then any subsequent reduction in such interest rate will not reduce the rate of interest payable pursuant to this Section 3.07 below the maximum rate permitted by applicable law until the total amount of interest accrued equals the amount of interest that would have accrued if such otherwise applicable interest rate as set forth in this Section 3.07 had at all times been in effect.


(b) Each Advance will be either a Base Rate Advance or a LIBOR Advance as provided in this Section. Each such Advance will be a Base Rate Advance for the period from the date of its borrowing to (but excluding) the third Business Day following the Liquidity Provider's receipt of the Notice of Borrowing for such Advance. Thereafter, such Advance shall be a LIBOR Advance; provided that the Borrower (at the direction of the Controlling Party, so long as the Liquidity Provider is not the Controlling Party) may (x) convert the Final Advance into a Base Rate Advance on the last day of an Interest Period for such Advance by giving the Liquidity Provider no less than four Business Days' prior written notice of such election or (y) elect to maintain the Final Advance as a Base Rate Advance by not requesting a conversion of the Final Advance to a LIBOR Advance under Clause (5) of the applicable Notice of Borrowing (or, if such Final Advance is deemed to have been made without delivery of a Notice of Borrowing pursuant to Section 2.06, by requesting, prior to 11:00 AM on the first Business Day immediately following the Borrower's receipt of the applicable Termination Notice, such that such Final Advance not be converted from a Base Rate Advance to a LIBOR Advance).

(c) Each LIBOR Advance shall bear interest during each Interest Period at a rate per annum equal to the LIBOR Rate for such Interest Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on the last day of such Interest Period and, in the event of the payment of principal of such LIBOR Advance on a day other than such last day, on the date of such payment (to the extent of interest accrued on the amount of principal repaid).

(d) Each Base Rate Advance shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin for such Base Rate Advance, payable in arrears on each Regular Distribution Date and, in the event of the payment of principal of such Base Rate Advance on a day other than a Regular Distribution Date, on the date of such payment (to the extent of interest accrued on the amount of principal repaid).

(e) Each Unapplied Provider Advance shall bear interest as provided in Section 3.07(b) hereof plus an amount equal to the amount by which
(i) the Investment Earnings plus 0.50% per annum on the outstanding amount from time to time of such Advance for the period for which interest is calculated pursuant to clause (ii) hereof exceeds (ii) the amount of interest on such Unapplied Provider Advance under Section 3.07(b). . (f) Each amount not paid by the Borrower when due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by applicable law, installments of interest on Advances but excluding Advances) shall bear interest at a rate per annum equal to the Base Rate plus 2.00% until paid.

(g) Each change in the Base Rate shall become effective immediately. The rates of interest specified in this Section 3.07 with respect to any Advance or other amount shall be referred to as the "Applicable Liquidity Rate".

Section 3.08. Replacement of Borrower. From time to time and subject to the successor Borrower's meeting the eligibility requirements set forth in Section 6.9 of the


Intercreditor Agreement applicable to the Subordination Agent, upon the effective date and time specified in a written and completed Notice of Replacement Subordination Agent in substantially the form of Annex V attached hereto (a "Notice of Replacement Subordination Agent") delivered to the Liquidity Provider by the then Borrower, the successor Borrower designated therein shall be substituted for as the Borrower for all purposes hereunder.

Section 3.09. Funding Loss Indemnification. The Borrower shall pay to the Liquidity Provider, upon the request of the Liquidity Provider, such amount or amounts as shall be sufficient (in the reasonable opinion of the Liquidity Provider) to compensate it for any loss, cost, or expense incurred by reason of the liquidation or redeployment of deposits or other funds acquired by the Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss of anticipated profits) incurred as a result of:

(1) Any repayment of a LIBOR Advance on a date other than the last day of the Interest Period for such Advance; or

(2) Any failure by the Borrower to borrow a LIBOR Advance on the date for borrowing specified in the relevant notice under Section 2.02.

Section 3.10. Illegality. Notwithstanding any other provision in this Agreement, if any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Liquidity Provider (or its Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for the Liquidity Provider (or its Lending Office) to maintain or fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity Provider, the outstanding principal amount of the LIBOR Advances shall be converted to Base Rate Advances (a) immediately upon demand of the Liquidity Provider, if such change or compliance with such request, in the judgment of the Liquidity Provider, requires immediate repayment; or (b) at the expiration of the last Interest Period to expire before the effective date of any such change or request.

Section 7.03. No Waiver: Remedies.

the Liquidity Provider, and the Liquidity Provider shall be liable to the Borrower, to the extent of any damages suffered by the Borrower which were the result of (A) the Liquidity Provider's willful misconduct or negligence in determining whether documents presented hereunder comply with the terms hereof, or (B) any breach by the Liquidity Provider of any of the terms of this Agreement, including, but not limited to, the Liquidity Provider's failure to make lawful payment hereunder after the delivery to it by the Borrower of a Notice of Borrowing strictly complying with the terms and conditions hereof.

(b) Neither the Liquidity Provider nor any of its officers, employees, director or affiliates shall be liable or responsible in any respect for (i) any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with this Agreement or any Notice of Borrowing delivered hereunder, or (ii) any action, inaction or omission which may be taken by it in good faith, absent willful misconduct or negligence (in which event the extent of the Liquidity Provider's potential liability to the Borrower shall be limited as set forth in the immediately preceding paragraph), in connection with this Agreement or any Notice of Borrowing.

Section 7.07. Costs, Expenses and Taxes.

In addition, the Borrower shall pay any and all recording, stamp and other similar taxes and fees payable or determined to be payable in connection with the execution, delivery, filing and recording of this Agreement, any other Operative Agreement and such other documents, and agrees to save the Liquidity Provider harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such taxes or fees.

Section 7.08. Binding Effect; Participations.

(a) This Agreement shall be binding upon and inure to the benefit of the Borrower and the Liquidity Provider and their respective successors and assigns, except that neither the Liquidity Provider (except as otherwise provided in this Section 7.08) nor (except as contemplated by Section 3.08) the Borrower shall have the right to assign its rights or obligations


hereunder or any interest herein without the prior written consent of the other party, subject to the requirements of Section 7.08(b). The Liquidity Provider may grant participations herein or in any of its rights hereunder (including, without limitation, funded participations and participations in rights to receive interest payments hereunder) and under the other Operative Agreements to such Persons as (not including Atlas or any affiliate of Atlas) the Liquidity Provider may in its sole discretion select, subject to the requirements of
Section 7.08(b). No such participation by the Liquidity Provider, however, will relieve the Liquidity Provider of its obligations hereunder. In connection with any participation or any proposed participation, the Liquidity Provider may disclose to the participant or the proposed participant any information that the Borrower is required to deliver or to disclose to the Liquidity Provider pursuant to this Agreement. The Borrower acknowledges and agrees that the Liquidity Provider's source of funds may derive in part from its participants. Accordingly, references in this Agreement and the other Operative Agreements to determinations, reserve and capital adequacy requirements, increased costs, reduced receipts, additional amounts due pursuant to Section 3.03(a) and the like as they pertain to the Liquidity Provider shall be deemed also to include those of each of its participants (subject, in each case, to the maximum amount that would have been incurred by or attributable to the Liquidity Provider directly if the Liquidity Provider, rather than the participant, had held the interest participated).

(b) If, pursuant to subsection (a) above, the Liquidity Provider sells any participation in this Agreement to any bank or other entity (each, a "Transferee"), then, concurrently with the effectiveness of such participation, the Transferee shall (i) represent to the Liquidity Provider (for the benefit of the Liquidity Provider and the Borrower) either (A) that it is incorporated under the laws of the United States or a state thereof or (B) that under applicable law and treaties, no taxes will be required to be withheld with respect to any payments to be made to such Transferee in respect of this Agreement, (ii) furnish to the Liquidity Provider and the Borrower either (x) a statement that it is incorporated under the laws of the United States or a state thereof or (y) if it is not so incorporated, two copies of a properly completed United States Internal Revenue Service Form W-8 ECI or Form W-8 BEN, as appropriate, or other applicable form, certificate or document prescribed by the Internal Revenue Service certifying, in each case, such Transferee's entitlement to a complete exemption from United States federal withholding tax in respect to any and all payments to be made hereunder, and (iii) agree (for the benefit of the Liquidity Provider and the Borrower) to provide the Liquidity Provider and the Borrower a new Form W-8 ECI or Form W-8 BEN, as appropriate, (A) on or before the date that any such form expires or becomes obsolete or (B) after the occurrence of any event requiring a change in the most recent form previously delivered by it and prior to the immediately following due date of any payment by the Borrower hereunder, certifying in the case of a Form W-8 BEN or Form W-8 ECI that such Transferee is entitled to a complete exemption from United States federal withholding tax on payments under this Agreement. Unless the Borrower has received forms or other documents reasonably satisfactory to it (and required by applicable law) indicating that payments hereunder are not subject to United States federal withholding tax, the Borrower will withhold taxes as required by law from such payments at the applicable statutory rate.

Section 7.09. Severability. Any provision of this Agreement which is prohibited, unenforceable or not authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to


the extent of such prohibition, unenforceability or nonauthorization without invalidating the remaining provisions hereof or affecting the validity, enforceability or legality of such provision in any other jurisdiction.

Section 7.10. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

Section 7.11. Submission to Jurisdiction; Waiver of Jury Trial; Waiver of Immunity. (a) Each of the parties hereto hereby irrevocably and unconditionally:

(i) submits for itself and its property in any legal action or proceeding relating to this Agreement or any other Operative Agreement, or for recognition and enforcement of any judgment in respect hereof or thereof, to the nonexclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and the appellate courts from any thereof;

(ii) consents that any such action or proceeding may be brought in such courts, and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(iii) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form and mail), postage prepaid, to each party hereto at its address set forth in Section 7.02 hereof, or at such other address of which the Liquidity Provider shall have been notified pursuant thereto; and

(iv) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction.

(b) THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING ESTABLISHED, including, without limitation, contract claims, tort claims, breach of duty claims and all other common law and statutory claims. The Borrower and the Liquidity Provider each warrant and represent that it has reviewed this waiver with its legal counsel, and that it knowingly and voluntarily waives its jury trial rights following consultation with such legal counsel. THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.


Section 7.12. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto on separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 7.13. Entirety. This Agreement, the Intercreditor Agreement and the other Operative Agreements to which the Liquidity Provider is a party constitute the entire agreement of the parties hereto with respect to the subject matter hereof and supersedes all prior understandings and agreements of such parties.

Section 7.14. Headings. Section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

Section 7.15. LIQUIDITY PROVIDER'S OBLIGATION TO MAKE ADVANCES. EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE OBLIGATIONS OF THE LIQUIDITY PROVIDER TO MAKE ADVANCES HEREUNDER, AND THE BORROWER'S RIGHTS TO DELIVER NOTICES OF BORROWING REQUESTING THE MAKING OF ADVANCES HEREUNDER, SHALL BE UNCONDITIONAL AND IRREVOCABLE, AND SHALL BE PAID OR PERFORMED, IN EACH CASE STRICTLY IN ACCORDANCE WITH THE TERMS OF THIS AGREEMENT.

Section 2.02. Making the Advances.

Annex III attached hereto, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Commitment at such time, and shall be used to fund the Class C Cash Collateral Account in accordance with said Section 3.6(c) and Section 3.6(f) of the Intercreditor Agreement.

(d) A Final Advance shall be made in a single Borrowing upon the receipt by the Borrower of a Termination Notice from the Liquidity Provider pursuant to Section 6.01 hereof by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex IV attached hereto, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Commitment at such time, and shall be used to fund the Class C Cash Collateral Account (in accordance with Section 3.6(i) of the Intercreditor Agreement) and Section 3.6(f) of the Intercreditor Agreement.

(f) Upon the making of any Advance requested pursuant to a Notice of Borrowing, in accordance with the Borrower's payment instructions, the Liquidity Provider shall be fully discharged of its obligation hereunder with respect to such Notice of Borrowing, and the Liquidity Provider shall not thereafter be obligated to make any further Advances hereunder in respect of such Notice of Borrowing to the Borrower or to any other Person. If the Liquidity Provider makes an Advance requested pursuant to a Notice of Borrowing before 12:00 Noon (New York City time) on the second Business Day after the date of payment specified in said Section 2.02(e), the Liquidity Provider shall have fully discharged its obligations hereunder with respect to such Advance and an event of default shall not have occurred hereunder. Following the making of any Advance pursuant to Section 2.02(b), (c) or (d) hereof to fund the Class C Cash Collateral Account, the Liquidity Provider shall have no interest in or rights to the Class C

9

Cash Collateral Account, such Advance or any other amounts from time to time on deposit in the Class C Cash Collateral Account; provided that the foregoing shall not affect or impair the obligations of the Subordination Agent to make the distributions contemplated by Section 3.6(e) or (f) of the Intercreditor Agreement. By paying to the Borrower proceeds of Advances requested by the Borrower in accordance with the provisions of this Agreement, the Liquidity Provider makes no representation as to, and assumes no responsibility for, the correctness or sufficiency for any purpose of the amount of the Advances so made and requested.

Section 2.03. Fees. The Borrower agrees to pay to the Liquidity Provider the fees set forth in the MSCS Fee Letter.

Section 2.04. Reduction or Termination of the Maximum Commitment.

(a) Automatic Reduction. Promptly following each date on which the Required Amount is reduced as a result of a reduction in the Pool Balance of the Class C Certificates or otherwise, the Maximum Commitment shall automatically be reduced to an amount equal to such reduced Required Amount (as calculated by the Borrower). The Borrower shall give notice of any such automatic reduction of the Maximum Commitment to the Liquidity Provider within two Business Days thereof. The failure by the Borrower to furnish any such notice shall not affect such automatic reduction of the Maximum Commitment.

(b) Termination. Upon the making of any Provider Advance or Final Advance hereunder or the occurrence of the Termination Date, the obligation of the Liquidity Provider to make further Advances hereunder shall automatically and irrevocably terminate, and the Borrower shall not be entitled to request any further Borrowing hereunder.

Section 2.05. Repayments of Interest Advances or the Final Advance. Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby agrees, without notice of an Advance or demand for repayment from the Liquidity Provider (which notice and demand are hereby waived by the Borrower), to pay, or to cause to be paid, to the Liquidity Provider on each date on which the Liquidity Provider shall make an Interest Advance or the Final Advance, an amount equal to (a) the amount of such Advance (any such Advance, until repaid, is referred to herein as an "Unpaid Advance"), plus (b) interest on the amount of each such Unpaid Advance as provided in Section 3.07 hereof; provided that if
(i) the Liquidity Provider shall make a Provider Advance at any time after making one or more Interest Advances which shall not have been repaid in accordance with this Section 2.05 or (ii) this Liquidity Facility shall become a Downgraded Facility or Non-Extended Facility at any time when unreimbursed Interest Advances have reduced the Maximum Commitment to zero, then such Interest Advances shall cease to constitute Unpaid Advances and shall be deemed to have been changed into an Applied Downgrade Advance or Applied Non-Extension Advance for all purposes of this Agreement (including, without limitation, for the purpose of determining when such Interest Advance is required to be repaid to the Liquidity Provider in accordance with Section 2.06 and for the purposes of Section 2.06(b)). The Borrower and the Liquidity Provider agree that the repayment in full of each Interest Advance and Final Advance on the date such Advance is made is intended to be a contemporaneous exchange for new value given to the Borrower by the Liquidity Provider.

10

Section 2.06. Repayments of Provider Advances. (a) Amounts advanced hereunder in respect of a Provider Advance shall be deposited in the Class C Cash Collateral Account, invested and withdrawn from the Class C Cash Collateral Account as set forth in Sections 3.6(c), (d) and (f) of the Intercreditor Agreement. The Borrower agrees to pay to the Liquidity Provider, on each Regular Distribution Date, commencing on the first Regular Distribution Date after the making of a Provider Advance, interest on the principal amount of any such Provider Advance as provided in Section 3.07; provided, however, that amounts in respect of a Provider Advance withdrawn from the Class C Cash Collateral Account for the purpose of paying interest on the Class C Certificates in accordance with Section 3.6(f) of the Intercreditor Agreement (the amount of any such withdrawal being (x) in the case of a Downgrade Advance, an "Applied Downgrade Advance" and (y) in the case of a Non-Extension Advance, an "Applied Non-Extension Advance" and, together with an Applied Downgrade Advance, an "Applied Provider Advance") shall thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon; provided further, however, that if, following the making of a Provider Advance, the Liquidity Provider delivers a Termination Notice to the Borrower pursuant to
Section 6.01 hereof, such Provider Advance shall thereafter be treated as a Final Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon. Subject to Sections 2.07 and 2.09 hereof, immediately upon the withdrawal of any amounts from the Class C Cash Collateral Account on account of a reduction in the Required Amount, the Borrower shall repay to the Liquidity Provider a portion of the Provider Advances in a principal amount equal to such reduction, plus interest on the principal amount prepaid as provided in Section 3.07 hereof.

(b) At any time when an Applied Provider Advance (or any portion thereof) is outstanding, upon the deposit in the Class C Cash Collateral Account of any amount pursuant to clause "third" of Section 2.4(b) of the Intercreditor Agreement, clause "third" of Section 3.2 of the Intercreditor Agreement or clause "fourth" of Section 3.3 of the Intercreditor Agreement (any such amount being a "Replenishment Amount") for the purpose of replenishing or increasing the balance thereof up to the Required Amount at such time, (i) the aggregate outstanding principal amount of all Applied Provider Advances (and of Provider Advances treated as an Interest Advance for purposes of determining the Applicable Liquidity Rate for interest payable thereon) shall be automatically reduced by the amount of such Replenishment Amount and (ii) the aggregate outstanding principal amount of all Unapplied Provider Advances shall be automatically increased by the amount of such Replenishment Amount.

(c) Upon the provision of a Replacement Liquidity Facility in replacement of this Agreement in accordance with Section 3.6(e) of the Intercreditor Agreement, amounts remaining on deposit in the Class C Cash Collateral Account after giving effect to any Applied Provider Advance on the date of such replacement shall be reimbursed to the Liquidity Provider, but only to the extent such amounts are necessary to repay in full to the Liquidity Provider all amounts owing to it hereunder.

11

Section 2.07. Payments to the Liquidity Provider Under the Intercreditor Agreement. In order to provide for payment or repayment to the Liquidity Provider of any amounts hereunder, the Intercreditor Agreement provides that amounts available and referred to in Articles II and III of the Intercreditor Agreement, to the extent payable to the Liquidity Provider pursuant to the terms of the Intercreditor Agreement (including, without limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid to the Liquidity Provider in accordance with the terms thereof. Amounts so paid to the Liquidity Provider shall be applied by the Liquidity Provider to Liquidity Obligations then due and payable in accordance with the Intercreditor Agreement or, if not provided for in the Intercreditor Agreement, then in such manner as the Liquidity Provider shall deem appropriate.

Section 2.08. Book Entries. The Liquidity Provider shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower resulting from Advances made from time to time and the amounts of principal and interest payable hereunder and paid from time to time in respect thereof; provided, however, that the failure by the Liquidity Provider to maintain such account or accounts shall not affect the obligations of the Borrower in respect of Advances.

Section 2.09. Payments from Available Funds Only. All payments to be made by the Borrower under this Agreement shall be made only from the amounts that constitute Scheduled Payments, Special Payments or payments under
Section 8.1 or 9.1, as the case may be, of the Participation Agreements and
Section 6 of the Note Purchase Agreement and only to the extent that the Borrower shall have sufficient income or proceeds therefrom to enable the Borrower to make payments in accordance with the terms hereof after giving effect to the priority of payments provisions set forth in the Intercreditor Agreement. The Liquidity Provider agrees that it will look solely to such amounts to the extent available for distribution to it as provided in the Intercreditor Agreement and this Agreement and that the Borrower, in its individual capacity, is not personally liable to it for any amounts payable or liability under this Agreement except as expressly provided in this Agreement, the Intercreditor Agreement or any Participation Agreement. Amounts on deposit in the Class C Cash Collateral Account shall be available to the Borrower to make payments under this Agreement only to the extent and for the purposes expressly contemplated in Section 3.6(f) of the Intercreditor Agreement.

Section 2.10. Extension of the Expiry Date; Non-Extension Advance. The Expiry Date shall be automatically extended, effective on the 25th day prior to each Expiry Date (unless such Expiry Date is on or after the date that is 15 days after the Final Legal Distribution Date for the Class C Certificates), for a period of 364 days after such Expiry Date (unless the obligations of the Liquidity Provider are earlier terminated in accordance with the terms hereof), without the necessity of any act on the part of the Borrower or the Liquidity Provider, unless the Liquidity Provider shall advise the Borrower prior to such 25th day that it does not agree to such extension of such Expiry Date, in which event (and if the Liquidity Provider shall not have been replaced in accordance with Section 3.6(e) of the Intercreditor Agreement), the Borrower shall be entitled on and after such 25th day (but prior to such Expiry Date) to request a Non-Extension Advance in accordance with Section 2.02(b) hereof and Section 3.6(d) of the Intercreditor Agreement.

ARTICLE III

OBLIGATIONS OF THE BORROWER

Section 3.01. Increased Costs. The Borrower shall pay to the Liquidity Provider from time to time such amounts as may be necessary to compensate the Liquidity Provider for any increased costs incurred by the Liquidity Provider which are attributable to its making or maintaining any LIBOR Advances hereunder or its obligation to make any such Advances hereunder, or any reduction in any amount receivable by the Liquidity Provider under this Agreement or the Intercreditor Agreement in respect of any such Advances or such obligation (such increases in costs and reductions in amounts receivable being herein called "Additional Costs"), resulting from any change after the date of this Agreement in U.S. federal, state, municipal, or foreign laws or regulations ("Regulatory Change") which changes the basis of taxation of any amounts payable to the Liquidity Provider under this Agreement in respect of any such Advances (other than Excluded Taxes). The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.01 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.01 of the effect of any Regulatory Change on its costs of making or maintaining Advances or on amounts receivable by it in respect of Advances, and of the additional amounts required to compensate the Liquidity Provider in respect of any Additional Costs, shall be prima facie evidence of the amount owed under this Section.

Section 3.02. Capital Adequacy. If (1) the adoption, after the date hereof, of any applicable governmental law, rule or regulation regarding capital adequacy, (2) any change, after the date hereof, in the interpretation or administration of any such law, rule or regulation by any central bank or other governmental authority charged with the interpretation or administration thereof or (3) compliance by the Liquidity Provider or any corporation controlling the Liquidity Provider with any applicable guideline or request of general applicability, issued after the date hereof, by any central bank or other governmental authority (whether or not having the force of law) that constitutes a change of the nature described in clause (2), has the effect of requiring an increase in the amount of capital required to be maintained by the Liquidity Provider or any corporation controlling the Liquidity Provider, and such increase is based upon the Liquidity Provider's obligations hereunder and other similar obligations, the Borrower shall pay to the Liquidity Provider from time to time such additional amount or amounts as are necessary to compensate the Liquidity Provider for such portion of such increase as shall be reasonably allocable to the Liquidity Provider's obligations to the Borrower hereunder. The Liquidity

13

Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise materially disadvantageous to the Liquidity Provider.

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.02 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.02 of the effect of any increase in the amount of capital required to be maintained by the Liquidity Provider and of the amount allocable to the Liquidity Provider's obligations to the Borrower hereunder shall be prima facie evidence of the amounts owed under this Section.

Section 3.03. Payments Free of Deductions. (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without reduction for or on account of, any present or future stamp or other taxes, levies, imposts, duties, charges, fees, deductions, withholdings, restrictions or conditions of any nature whatsoever now or hereafter imposed, levied, collected, withheld or assessed, excluding Excluded Taxes (such non-excluded taxes being referred to herein, collectively, as "Non-Excluded Taxes" and, individually, as a "Non-Excluded Tax"). If any Non-Excluded Taxes are required to be withheld from any amounts payable to the Liquidity Provider under this Agreement, the amounts so payable to the Liquidity Provider shall be increased to the extent necessary to yield to the Liquidity Provider (after payment of all Non-Excluded Taxes) interest or any other such amounts payable under this Agreement at the rates or in the amounts specified in this Agreement. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider. From time to time upon the reasonable request of the Borrower, the Liquidity Provider agrees to provide to the Borrower two original Internal Revenue Service Forms W-8 BEN or W-8 ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that the Liquidity Provider is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement.

(b) All payments (including, without limitation, Advances) made by the Liquidity Provider under this Agreement shall be made free and clear of, and without reduction for or on account of, any Taxes. If any Taxes are required to be withheld or deducted from any amounts payable to the Borrower under this Agreement, the Liquidity Provider shall (i) within the time prescribed therefor by applicable law pay to the appropriate governmental or taxing authority the full amount of any such Taxes (and any additional Taxes in respect of the payment required under clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) pay to the Borrower an additional amount which (after deduction of all such Taxes) will be sufficient to yield to the

14

Borrower the full amount which would have been received by it had no such withholding or deduction been made. Within 30 days after the date of each payment hereunder, the Liquidity Provider shall furnish to the Borrower the original or a certified copy of (or other documentary evidence of) the payment of the Taxes applicable to such payment.

Section 3.04. Payments. The Borrower shall make or cause to be made each payment to the Liquidity Provider under this Agreement so as to cause the same to be received by the Liquidity Provider not later than 1:00 P.M. (New York City time) on the day when due. The Borrower shall make all such payments in lawful money of the United States of America, to the Liquidity Provider in immediately available funds, by wire transfer to Citibank, N.A., New York, NY, ABA# 021000089, Account Name: Morgan Stanley Capital Services, Inc., Account # 4072-4601, Reference: Atlas Air, Inc., 2000-1B.

Section 3.05. Computations. All computations of interest based on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the LIBOR Rate shall be made on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable.

Section 3.06. Payment on Non-Business Days. Whenever any payment to be made hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and no additional interest shall be due as a result (and if so made, shall be deemed to have been made when due). If any payment in respect of interest on an Advance is so deferred to the next succeeding Business Day, such deferral shall not delay the commencement of the next Interest Period for such Advance (if such Advance is a LIBOR Advance) or reduce the number of days for which interest will be payable on such Advance on the next interest payment date for such Advance.

Section 3.07. Interest. (a) Subject to Section 2.09, the Borrower shall pay, or shall cause to be paid, without duplication, interest on
(i) the unpaid principal amount of each Advance from and including the date of such Advance (or, in the case of an Applied Provider Advance, from and including the date on which the amount thereof was withdrawn from the Class C Cash Collateral Account to pay interest on the Class C Certificates) to but excluding the date such principal amount shall be paid in full (or, in the case of an Applied Provider Advance, the date on which the Class C Cash Collateral Account is fully replenished in respect of such Advance) and (ii) any other amount due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by law, installments of interest on Advances or any such other amount) which is not paid when due (whether at stated maturity, by acceleration or otherwise) from and including the due date thereof to but excluding the date such amount is paid in full, in each such case, at a fluctuating interest rate per annum for each day equal to the Applicable Liquidity Rate (as defined below) for such Advance or such other amount as in effect for such day, but in no event at a rate per annum greater than the maximum rate permitted by applicable law; provided, however, that, if at any time the otherwise applicable interest rate as set forth in this Section 3.07 shall exceed the maximum rate permitted by applicable law, then any subsequent reduction in such interest rate will not reduce the rate of interest payable pursuant to this Section 3.07 below the maximum rate permitted by applicable law until the total amount of

15

interest accrued equals the amount of interest that would have accrued if such otherwise applicable interest rate as set forth in this Section 3.07 had at all times been in effect.

(b) Each Advance will be either a Base Rate Advance or a LIBOR Advance as provided in this Section. Each such Advance will be a Base Rate Advance for the period from the date of its borrowing to (but excluding) the third Business Day following the Liquidity Provider's receipt of the Notice of Borrowing for such Advance. Thereafter, such Advance shall be a LIBOR Advance; provided that the Borrower (at the direction of the Controlling Party, so long as the Liquidity Provider is not the Controlling Party) may (x) convert the Final Advance into a Base Rate Advance on the last day of an Interest Period for such Advance by giving the Liquidity Provider no less than four Business Days' prior written notice of such election or (y) elect to maintain the Final Advance as a Base Rate Advance by not requesting a conversion of the Final Advance to a LIBOR Advance under Clause (5) of the applicable Notice of Borrowing (or, if such Final Advance is deemed to have been made without delivery of a Notice of Borrowing pursuant to Section 2.06, by requesting, prior to 11:00 AM on the first Business Day immediately following the Borrower's receipt of the applicable Termination Notice, such that such Final Advance not be converted from a Base Rate Advance to a LIBOR Advance).

(c) Each LIBOR Advance shall bear interest during each Interest Period at a rate per annum equal to the LIBOR Rate for such Interest Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on the last day of such Interest Period and, in the event of the payment of principal of such LIBOR Advance on a day other than such last day, on the date of such payment (to the extent of interest accrued on the amount of principal repaid).

(d) Each Base Rate Advance shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin for such Base Rate Advance, payable in arrears on each Regular Distribution Date and, in the event of the payment of principal of such Base Rate Advance on a day other than a Regular Distribution Date, on the date of such payment (to the extent of interest accrued on the amount of principal repaid).

(e) Each Unapplied Provider Advance shall bear interest as provided in Section 3.07(b) hereof plus an amount equal to the amount by which
(i) the Investment Earnings plus 0.50% per annum on the outstanding amount from time to time of such Advance for the period for which interest is calculated pursuant to clause (ii) hereof exceeds (ii) the amount of interest on such Unapplied Provider Advance under Section 3.07(b).

(f) Each amount not paid by the Borrower when due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by applicable law, installments of interest on Advances but excluding Advances) shall bear interest at a rate per annum equal to the Base Rate plus 2.00% until paid.

(g) Each change in the Base Rate shall become effective immediately. The rates of interest specified in this Section 3.07 with respect to any Advance or other amount shall be referred to as the "Applicable Liquidity Rate".

16

Section 3.08. Replacement of Borrower. From time to time and subject to the successor Borrower's meeting the eligibility requirements set forth in Section 6.9 of the Intercreditor Agreement applicable to the Subordination Agent, upon the effective date and time specified in a written and completed Notice of Replacement Subordination Agent in substantially the form of Annex V attached hereto (a "Notice of Replacement Subordination Agent") delivered to the Liquidity Provider by the then Borrower, the successor Borrower designated therein shall be substituted for as the Borrower for all purposes hereunder.

Section 3.09. Funding Loss Indemnification. The Borrower shall pay to the Liquidity Provider, upon the request of the Liquidity Provider, such amount or amounts as shall be sufficient (in the reasonable opinion of the Liquidity Provider) to compensate it for any loss, cost, or expense incurred by reason of the liquidation or redeployment of deposits or other funds acquired by the Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss of anticipated profits) incurred as a result of:

(1) Any repayment of a LIBOR Advance on a date other than the last day of the Interest Period for such Advance; or

(2) Any failure by the Borrower to borrow a LIBOR Advance on the date for borrowing specified in the relevant notice under Section 2.02.

Section 3.10. Illegality. Notwithstanding any other provision in this Agreement, if any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Liquidity Provider (or its Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for the Liquidity Provider (or its Lending Office) to maintain or fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity Provider, the outstanding principal amount of the LIBOR Advances shall be converted to Base Rate Advances (a) immediately upon demand of the Liquidity Provider, if such change or compliance with such request, in the judgment of the Liquidity Provider, requires immediate repayment; or (b) at the expiration of the last Interest Period to expire before the effective date of any such change or request.

Section 7.05. Indemnification; Survival of Certain Provisions. The Liquidity Provider shall be indemnified hereunder to the extent and in the manner described in Section 9.1 of the Leased Aircraft Participation Agreement,

22

(b) Neither the Liquidity Provider nor any of its officers, employees, director or affiliates shall be liable or responsible in any respect for (i) any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with this Agreement or any Notice of Borrowing delivered hereunder, or (ii) any action, inaction or omission which may be taken by it in good faith, absent willful misconduct or negligence (in which event the extent of the Liquidity Provider's potential liability to the Borrower shall be limited as set forth in the immediately preceding paragraph), in connection with this Agreement or any Notice of Borrowing.

Section 7.07. Costs, Expenses and Taxes. The Borrower agrees to pay, or cause to be paid (A) on the Effective Date and on such later date or dates on which the Liquidity Provider shall make demand, all reasonable out-of-pocket costs and expenses (including, without limitation, the reasonable fees and expenses of outside counsel for the Liquidity Provider) of the Liquidity Provider in connection with the preparation, negotiation, execution, delivery, filing and recording of this Agreement, any other Operative Agreement and any other documents which may be delivered in connection with this Agreement and (B) on demand, all reasonable costs and expenses (including reasonable counsel fees and expenses) of the Liquidity Provider in connection with (i) the enforcement of this Agreement or any other Operative Agreement, (ii) the modification or amendment of, or supplement to, this Agreement or any other Operative Agreement or such other documents which may be delivered in connection herewith or therewith (whether or not the same shall become effective) or (iii) any action or proceeding relating to any order, injunction, or other process or decree restraining or seeking to restrain the Liquidity Provider from paying any amount under this Agreement, the Intercreditor Agreement or any other Operative Agreement or otherwise affecting the application of funds in the Class C Cash Collateral Account. In addition, the Borrower shall pay any and all recording, stamp and other similar taxes and fees payable or determined to be payable in connection with the execution, delivery, filing and recording of this Agreement, any other Operative Agreement and such other documents, and agrees to save the Liquidity Provider harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such taxes or fees.

Section 7.08. Binding Effect; Participations.

(a) This Agreement shall be binding upon and inure to the benefit of the Borrower and the Liquidity Provider and their respective successors and assigns, except that neither the Liquidity Provider (except as otherwise provided in this Section 7.08) nor (except as contemplated by Section 3.08) the Borrower shall have the right to assign its rights or obligations hereunder or any interest herein without the prior written consent of the other party, subject to the requirements of Section 7.08(b). The Liquidity Provider may grant participations herein or in any of its rights hereunder (including, without limitation, funded participations and participations in rights to receive interest payments hereunder) and under the other Operative Agreements to such Persons as (not including Atlas or any affiliate of Atlas) the Liquidity Provider may in its sole discretion select, subject to the requirements of
Section 7.08(b). No such participation by the Liquidity Provider, however, will relieve the Liquidity Provider of its obligations hereunder. In

23

connection with any participation or any proposed participation, the Liquidity Provider may disclose to the participant or the proposed participant any information that the Borrower is required to deliver or to disclose to the Liquidity Provider pursuant to this Agreement. The Borrower acknowledges and agrees that the Liquidity Provider's source of funds may derive in part from its participants. Accordingly, references in this Agreement and the other Operative Agreements to determinations, reserve and capital adequacy requirements, increased costs, reduced receipts, additional amounts due pursuant to Section 3.03(a) and the like as they pertain to the Liquidity Provider shall be deemed also to include those of each of its participants (subject, in each case, to the maximum amount that would have been incurred by or attributable to the Liquidity Provider directly if the Liquidity Provider, rather than the participant, had held the interest participated).

(b) If, pursuant to subsection (a) above, the Liquidity Provider sells any participation in this Agreement to any bank or other entity (each, a "Transferee"), then, concurrently with the effectiveness of such participation, the Transferee shall (i) represent to the Liquidity Provider (for the benefit of the Liquidity Provider and the Borrower) either (A) that it is incorporated under the laws of the United States or a state thereof or (B) that under applicable law and treaties, no taxes will be required to be withheld with respect to any payments to be made to such Transferee in respect of this Agreement, (ii) furnish to the Liquidity Provider and the Borrower either (x) a statement that it is incorporated under the laws of the United States or a state thereof or (y) if it is not so incorporated, two copies of a properly completed United States Internal Revenue Service Form W-8 ECI or Form W-8 BEN, as appropriate, or other applicable form, certificate or document prescribed by the Internal Revenue Service certifying, in each case, such Transferee's entitlement to a complete exemption from United States federal withholding tax in respect to any and all payments to be made hereunder, and (iii) agree (for the benefit of the Liquidity Provider and the Borrower) to provide the Liquidity Provider and the Borrower a new Form W-8 ECI or Form W-8 BEN, as appropriate, (A) on or before the date that any such form expires or becomes obsolete or (B) after the occurrence of any event requiring a change in the most recent form previously delivered by it and prior to the immediately following due date of any payment by the Borrower hereunder, certifying in the case of a Form W-8 BEN or Form W-8 ECI that such Transferee is entitled to a complete exemption from United States federal withholding tax on payments under this Agreement. Unless the Borrower has received forms or other documents reasonably satisfactory to it (and required by applicable law) indicating that payments hereunder are not subject to United States federal withholding tax, the Borrower will withhold taxes as required by law from such payments at the applicable statutory rate.

Section 7.09. Severability. Any provision of this Agreement which is prohibited, unenforceable or not authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition, unenforceability or nonauthorization without invalidating the remaining provisions hereof or affecting the validity, enforceability or legality of such provision in any other jurisdiction.

Section 7.10. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

24

Section 7.11. Submission to Jurisdiction; Waiver of Jury Trial; Waiver of Immunity. (a) Each of the parties hereto hereby irrevocably and unconditionally:

(i) submits for itself and its property in any legal action or proceeding relating to this Agreement or any other Operative Agreement, or for recognition and enforcement of any judgment in respect hereof or thereof, to the nonexclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and the appellate courts from any thereof;

(ii) consents that any such action or proceeding may be brought in such courts, and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(iii) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form and mail), postage prepaid, to each party hereto at its address set forth in Section 7.02 hereof, or at such other address of which the Liquidity Provider shall have been notified pursuant thereto; and

(iv) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction.

(b) THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING ESTABLISHED, including, without limitation, contract claims, tort claims, breach of duty claims and all other common law and statutory claims. The Borrower and the Liquidity Provider each warrant and represent that it has reviewed this waiver with its legal counsel, and that it knowingly and voluntarily waives its jury trial rights following consultation with such legal counsel. THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

Section 7.12. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto on separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

25

Section 7.13. Entirety. This Agreement, the Intercreditor Agreement and the other Operative Agreements to which the Liquidity Provider is a party constitute the entire agreement of the parties hereto with respect to the subject matter hereof and supersedes all prior understandings and agreements of such parties.

Section 7.14. Headings. Section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE OBLIGATIONS OF THE LIQUIDITY PROVIDER TO MAKE ADVANCES HEREUNDER, AND THE BORROWER'S RIGHTS TO DELIVER NOTICES OF BORROWING REQUESTING THE MAKING OF ADVANCES HEREUNDER, SHALL BE UNCONDITIONAL AND IRREVOCABLE, AND SHALL BE PAID OR PERFORMED, IN EACH CASE STRICTLY IN ACCORDANCE WITH THE TERMS OF THIS AGREEMENT.

SECTION 1. Escrow Agent.

Section 1.01. Appointment of Escrow Agent. Each of the Placement Agents, for and on behalf of each of the Investors, hereby irrevocably appoints, authorizes and directs the Escrow Agent to act as escrow agent and fiduciary hereunder and under the Deposit Agreement for such specific purposes and with such powers as are specifically delegated to the Escrow Agent by the terms of this Agreement, together with such other powers as are reasonably incidental thereto. Any and all money received and held by the Escrow Agent under this Agreement or the Deposit Agreement shall be held in escrow by the Escrow Agent in accordance with the terms of this Agreement. This Agreement is irrevocable and the Investors' rights with respect to any monies received and held in escrow by the Escrow Agent under this Agreement or the Deposit Agreement shall only be as provided under the terms and conditions of this Agreement and the Deposit Agreement. The Escrow Agent (which term as used in this sentence shall include reference to its affiliates and its own and its affiliates' officers, directors, employees and agents): (a) shall have no duties or responsibilities except those expressly set forth in this Agreement; (b) shall not be responsible to the Pass Through Trustee or the Investors for any recitals, statements, representations or warranties of any person other then itself contained in this Agreement or the Deposit Agreement or for the failure by the Pass Through Trustee, the Investors or any other person or entity (other than the Escrow Agent) to perform any of its obligations hereunder (whether or not the Escrow Agent shall have any knowledge thereof); and (c) shall not be responsible for any action taken or omitted to be taken by it hereunder or provided for herein or in connection herewith, except for its own willful misconduct or gross negligence (or simple negligence in connection with the handling of funds).

Section 1.02. Instruction; Etc. The Placement Agents, for and on behalf of each of the Investors, hereby irrevocably instruct the Escrow Agent, and the Escrow Agent agrees, (a) to enter into the Deposit Agreement, (b) to appoint the Paying Agent as provided in this Agreement, (c) upon receipt at any time and from time to time prior to the Delivery Period Termination Date (as defined in the Note Purchase Agreement) of a certificate substantially in

2

the form of Exhibit B hereto (a "Withdrawal Certificate") executed by the Pass Through Trustee, together with an attached Notice of Purchase Withdrawal in substantially the form of Exhibit A to the Deposit Agreement duly completed by the Pass Through Trustee (the "Applicable Notice of Purchase Withdrawal" and the withdrawal to which it relates, a "Purchase Withdrawal"), immediately to execute the Applicable Notice of Purchase Withdrawal as Escrow Agent and transmit it to the Depositary by facsimile transmission in accordance with the Deposit Agreement; provided that, upon the request of the Pass Through Trustee after such transmission, the Escrow Agent shall cancel such Applicable Notice of Purchase Withdrawal, (d) upon receipt at any time and from time to time prior to the Delivery Period Termination Date of a certificate substantially in the form of Exhibit C hereto (a "Prepayment Withdrawal Certificate") executed by the Pass Through Trustee, together with an attached Notice of Prepayment Withdrawal in substantially the form of Exhibit B to the Deposit Agreement duly completed by the Pass Through Trustee (the "Applicable Notice of Prepayment Withdrawal" and the withdrawal to which it relates, a "Prepayment Withdrawal"), immediately to execute the Applicable Notice of Prepayment Withdrawal as Escrow Agent and transmit it to the Depositary by facsimile transmission in accordance with the Deposit Agreement; provided that, upon the request of the Pass Through Trustee after such transmission, the Escrow Agent shall cancel such Applicable Notice of Prepayment Withdrawal, and (e) if there are any undrawn amounts in the Account (as defined in the Deposit Agreement) on the earlier of (i) the Delivery Period Termination Date and (ii) the date on which the Escrow Agent receives notice from the Pass Through Trustee that the Pass Through Trustee's obligation to purchase Equipment Notes under the Note Purchase Agreement has terminated, to give notice to the Depositary (with a copy to the Paying Agent) substantially in the form of Exhibit C to the Deposit Agreement requesting a withdrawal of all of the remaining amount of the Deposit (as defined in the Deposit Agreement), together with accrued and unpaid interest on the Deposit to the date of withdrawal, on the 15th day after the date that such notice of withdrawal is given to the Depositary (or, if not a Business Day, on the next succeeding Business Day) (a "Final Withdrawal"), provided that if the day scheduled for the Final Withdrawal in accordance with the foregoing is within 10 days before a Regular Distribution Date, then the Escrow Agent shall request that such requested Final Withdrawal be made on such Regular Distribution Date (the date of such requested withdrawal, the "Final Withdrawal Date"). If for any reason the Escrow Agent shall have failed to give the Final Withdrawal Notice to the Depositary on or before December 31, 2000 (provided, that if a labor strike or work stoppage occurs at The Boeing Company prior to such date, such date shall be extended by adding thereto the number of days that each such labor strike or work stoppage continues in effect), and there are unwithdrawn amounts in the Account (as defined in the Deposit Agreement) on such date, the Final Withdrawal Date shall be deemed to be January 16, 2001 (or, if the December 31, 2000 date has been extended as provided in this sentence, the fifteenth day after the Delivery Period Termination Date).

Section 1.03. Initial Escrow Amount; Issuance of Escrow Receipts. The Escrow Agent hereby directs the Placement Agents to, and the Placement Agents hereby acknowledge that on the date hereof they shall, irrevocably deliver to the Depositary on behalf of the Escrow Agent, an amount in U.S. dollars ("Dollars") and immediately available funds equal to $124,639,000 for deposit on behalf of the Escrow Agent with the Depositary in accordance with Section 2.1 of the Deposit Agreement. The Placement Agents hereby instruct the Escrow Agent,

3

upon receipt of such sum from the Placement Agents, to confirm such receipt by executing and delivering to the Pass Through Trustee an Escrow Receipt in the form of Exhibit A hereto (an "Escrow Receipt"), (a) to be affixed by the Pass Through Trustee to each Certificate and (b) to evidence the same percentage interest (the "Escrow Interest") in the Account Amounts (as defined below) as the Fractional Undivided Interest in the Pass Through Trust evidenced by the Certificate to which it is to be affixed. The Escrow Agent shall provide to the Pass Through Trustee for attachment to each Certificate newly issued under and in accordance with the Pass Through Trust Agreement an executed Escrow Receipt as the Pass Through Trustee may from time to time request of the Escrow Agent. Each Escrow Receipt shall be registered by the Escrow Agent in a register (the "Register") maintained by the Escrow Agent in the same name and same manner as the Certificate to which it is attached and may not thereafter be detached from such Certificate to which it is to be affixed prior to the distribution of the Final Withdrawal (the "Final Distribution"). After the Final Distribution, no additional Escrow Receipts shall be issued and the Pass Through Trustee shall request the return to the Escrow Agent for cancellation of all outstanding Escrow Receipts.

Section 1.04. Payments to Receiptholders. All payments and distributions made to holders of an Escrow Receipt (collectively "Receiptholders") in respect of the Escrow Receipt shall be made only from amounts deposited in the Paying Agent Account (as defined below) ("Account Amounts"). Each Receiptholder, by its acceptance of an Escrow Receipt, agrees that (a) it will look solely to the Account Amounts for any payment or distribution due to such Receiptholder pursuant to the terms of the Escrow Receipt and this Agreement and (b) it will have no recourse to Atlas, the Pass Through Trustee, the Paying Agent or the Escrow Agent, except as expressly provided herein or in the Pass Through Trust Agreement. No Receiptholder shall have any right to vote or in any manner otherwise control the operation and management of the Paying Agent Account or the obligations of the parties hereto, nor shall anything set forth herein, or contained in the terms of the Escrow Receipt, be construed so as to constitute the Receiptholders from time to time as partners or members of an association.

Section 1.05. Mutilated, Destroyed, Lost or Stolen Escrow Receipt. If (a) any mutilated Escrow Receipt is surrendered to the Escrow Agent or the Escrow Agent receives evidence to its satisfaction of the destruction, loss or theft of any Escrow Receipt and (b) there is delivered to the Escrow Agent and the Pass Through Trustee such security, indemnity or bond, as may be required by them to hold each of them harmless, then, absent notice to the Escrow Agent or the Pass Through Trustee that such destroyed, lost or stolen Escrow Receipt has been acquired by a bona fide purchaser, and provided that the requirements of Section 8-405 of the Uniform Commercial Code in effect in any applicable jurisdiction are met, the Escrow Agent shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Escrow Receipt, a new Escrow Receipt or Escrow Receipts and of like Escrow Interest in the Account Amounts and bearing a number not contemporaneously outstanding.

In connection with the issuance of any new Escrow Receipt under this Section 1.05, the Escrow Agent may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Pass Through Trustee and the Escrow Agent) connected therewith.

4

Any duplicate Escrow Receipt issued pursuant to this Section 1.05 shall constitute conclusive evidence of the appropriate Escrow Interest in the Account Amounts, as if originally issued, whether or not the lost, stolen or destroyed Escrow Receipt shall be found at any time.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Escrow Receipts.

Section 1.06. Additional Escrow Amounts. On the date of any Purchase Withdrawal, the Pass Through Trustee may re-deposit with the Depositary some or all of the amounts so withdrawn in accordance with Section 2.4 of the Deposit Agreement.

Section 1.07. Resignation or Removal of Escrow Agent. Subject to the appointment and acceptance of a successor Escrow Agent as provided below, the Escrow Agent may resign at any time by giving 30 days' prior written notice thereof to the Investors, but may not otherwise be removed except for cause by the written consent of the Investors with respect to Investors representing Escrow Interests aggregating not less than a majority in interest in the Account Amounts (an "Action of Investors"). Upon any such resignation or removal, the Investors, by an Action of Investors, shall have the right to appoint a successor Escrow Agent. If no successor Escrow Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Escrow Agent's giving of notice of resignation or the removal of the retiring Escrow Agent, then the retiring Escrow Agent may appoint a successor Escrow Agent. Any successor Escrow Agent shall be a bank which has an office in the United States with a combined capital and surplus of at least $100,000,000. Upon the acceptance of any appointment as Escrow Agent hereunder by a successor Escrow Agent, such successor Escrow Agent shall enter into such documents as the Pass Through Trustee shall require and shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Escrow Agent, and the retiring Escrow Agent shall be discharged from its duties and obligations hereunder. No resignation or removal of the Escrow Agent shall be effective unless a written confirmation shall have been obtained from each of Moody's Investors Service, Inc. and Standard & Poor's Rating Group, a division of McGraw-Hill Inc. that the replacement of the Escrow Agent with the successor Escrow Agent will not result in (a) a reduction of the rating for the Certificates below the then current rating for the Certificates or (b) a withdrawal or suspension of the rating of the Certificates.

Section 1.08. Persons Deemed Owners. Prior to due presentment of a Certificate for registration of transfer, the Escrow Agent and the Paying Agent may treat the Person in whose name any Escrow Receipt is registered (as of the day of determination) as the owner of such Escrow Receipt for the purpose of receiving distributions pursuant to this Agreement and for all other purposes whatsoever, and neither the Escrow Agent nor the Paying Agent shall be affected by any notice to the contrary.

Section 1.09. Further Assurances. The Escrow Agent agrees to take such actions, and execute such other documents, as may be reasonably requested by the Pass Through

5

Trustee in order to effectuate the purposes of this Agreement and the performance by the Escrow Agent of its obligations hereunder.

SECTION 2. Paying Agent.

Section 2.01. Appointment of Paying Agent. The Escrow Agent hereby irrevocably appoints and authorizes the Paying Agent to act as its paying agent hereunder, for the benefit of the Investors, for such specific purposes and with such powers as are specifically delegated to the Paying Agent by the terms of this Agreement, together with such other powers as are reasonably incidental thereto. Any and all money received and held by the Paying Agent under this Agreement or the Deposit Agreement shall be held in the Paying Agent Account for the benefit of the Investors.

(whether or not the Paying Agent shall have any knowledge thereof); and (c)
shall not be responsible for any action taken or omitted to be taken by it hereunder or provided for herein or in connection herewith, except for its own willful misconduct or gross negligence (or simple negligence in connection with the handling of funds).

It is expressly understood by the parties hereto that the Paying Agent is acting as the paying agent of the Escrow Agent hereunder and that no amounts on deposit in the Paying Agent Account constitute part of the Trust Property.

Section 2.03. Payments from Paying Agent Account. The Escrow Agent hereby irrevocably instructs the Paying Agent, and the Paying Agent agrees to act, as follows:

(c) If any payment of interest or principal in respect of the Final Withdrawal is not received by the Paying Agent within five days of the applicable date when due, then it shall be distributed to Receiptholders after actual receipt by the Paying Agent on the same basis as a Special Payment is distributed under the Pass Through Trust Agreement.

(d) Upon the confirmation by the Paying Agent of receipt in the Paying Agent Account from the Depositary of any amount in respect of a Prepayment Withdrawal, the Paying Agent shall forthwith distribute the entire amount of such Prepayment Withdrawal upon not less than 15 days prior notice to the Receiptholders.

The Paying Agent agrees to file any other information reports as it may be required to file under United States law.

Section 2.05. Resignation or Removal of Paying Agent. Subject to the appointment and acceptance of a successor Paying Agent as provided below, the Paying Agent may resign at any time by giving 30 days' prior written notice thereof to the Escrow Agent, but may not otherwise be removed except for cause by the Escrow Agent. Upon any such resignation or removal, the Escrow Agent shall have the right to appoint a successor Paying Agent. If no successor Paying Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Paying Agent's giving of notice of resignation or the removal of the retiring Paying Agent, then the retiring Paying Agent may appoint a successor Paying Agent. Any Successor Paying Agent shall be a bank which has an office in the United States with a combined capital and surplus of at least $100,000,000. Upon the acceptance of any appointment as Paying Agent hereunder by a successor Paying Agent, such successor Paying Agent shall enter into such documents as the Escrow Agent shall require and shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Paying Agent, and the retiring Paying Agent shall be discharged from its duties and obligations hereunder.

Section 2.06. Notice of Prepayment Withdrawal and Final Withdrawal.

SECTION 3. Payments. If, notwithstanding the instructions in
Section 4 of the Deposit Agreement that all amounts payable to the Escrow Agent under the Deposit Agreement be paid by the Depositary directly to the Paying Agent or the Pass Through Trustee (depending on the circumstances), the Escrow Agent receives any payment thereunder, then the Escrow Agent shall forthwith pay such amount in Dollars and in immediately available funds by wire transfer to

SECTION 1. Escrow Agent.

Section 1.01. Appointment of Escrow Agent. Each of the Placement Agents, for and on behalf of each of the Investors, hereby irrevocably appoints, authorizes and directs the Escrow Agent to act as escrow agent and fiduciary hereunder and under the Deposit Agreement for such specific purposes and with such powers as are specifically delegated to the Escrow Agent by the terms of this Agreement, together with such other powers as are reasonably incidental thereto. Any and all money received and held by the Escrow Agent under this Agreement or the Deposit Agreement shall be held in escrow by the Escrow Agent in accordance with the terms of this Agreement. This Agreement is irrevocable and the Investors' rights with respect to any monies received and held in escrow by the Escrow Agent under this Agreement or the Deposit Agreement shall only be as provided under the terms and conditions of this Agreement and the Deposit Agreement. The Escrow Agent (which term as used in this sentence shall include reference to its affiliates and its own and its affiliates_ officers, directors, employees and agents): (a) shall have no duties or responsibilities except those expressly set forth in this Agreement; (b) shall not be responsible to the Pass Through Trustee or the Investors for any recitals, statements, representations or warranties of any person other then itself contained in this Agreement or the Deposit Agreement or for the failure by the Pass Through Trustee, the Investors or any other person or entity (other than the Escrow Agent) to perform any of its obligations hereunder (whether or not the Escrow Agent shall have any knowledge thereof); and (c) shall not be responsible for any action taken or omitted to be taken by it hereunder or provided for herein or in connection herewith, except for its own willful misconduct or gross negligence (or simple negligence in connection with the handling of funds).

Section 1.02. Instruction; Etc. The Placement Agents, for and on behalf of each of the Investors, hereby irrevocably instruct the Escrow Agent, and the Escrow Agent agrees, (a) to enter into the Deposit Agreement, (b) to appoint the Paying Agent as provided in this Agreement, (c) upon receipt at any time and from time to time prior to the Delivery Period Termination Date (as defined in the Note Purchase Agreement) of a certificate substantially in

2

the form of Exhibit B hereto (a "Withdrawal Certificate") executed by the Pass Through Trustee, together with an attached Notice of Purchase Withdrawal in substantially the form of Exhibit A to the Deposit Agreement duly completed by the Pass Through Trustee (the "Applicable Notice of Purchase Withdrawal" and the withdrawal to which it relates, a "Purchase Withdrawal"), immediately to execute the Applicable Notice of Purchase Withdrawal as Escrow Agent and transmit it to the Depositary by facsimile transmission in accordance with the Deposit Agreement; provided that, upon the request of the Pass Through Trustee after such transmission, the Escrow Agent shall cancel such Applicable Notice of Purchase Withdrawal, (d) upon receipt at any time and from time to time prior to the Delivery Period Termination Date of a certificate substantially in the form of Exhibit C hereto (a "Prepayment Withdrawal Certificate") executed by the Pass Through Trustee, together with an attached Notice of Prepayment Withdrawal in substantially the form of Exhibit B to the Deposit Agreement duly completed by the Pass Through Trustee (the "Applicable Notice of Prepayment Withdrawal" and the withdrawal to which it relates, a "Prepayment Withdrawal"), immediately to execute the Applicable Notice of Prepayment Withdrawal as Escrow Agent and transmit it to the Depositary by facsimile transmission in accordance with the Deposit Agreement; provided that, upon the request of the Pass Through Trustee after such transmission, the Escrow Agent shall cancel such Applicable Notice of Prepayment Withdrawal, and (e) if there are any undrawn amounts in the Account (as defined in the Deposit Agreement) on the earlier of (i) the Delivery Period Termination Date and (ii) the date on which the Escrow Agent receives notice from the Pass Through Trustee that the Pass Through Trustee's obligation to purchase Equipment Notes under the Note Purchase Agreement has terminated, to give notice to the Depositary (with a copy to the Paying Agent) substantially in the form of Exhibit C to the Deposit Agreement requesting a withdrawal of all of the remaining amount of the Deposit (as defined in the Deposit Agreement), together with accrued and unpaid interest on the Deposit to the date of withdrawal, on the 15th day after the date that such notice of withdrawal is given to the Depositary (or, if not a Business Day, on the next succeeding Business Day) (a "Final Withdrawal"), provided that if the day scheduled for the Final Withdrawal in accordance with the foregoing is within 10 days before a Regular Distribution Date, then the Escrow Agent shall request that such requested Final Withdrawal be made on such Regular Distribution Date (the date of such requested withdrawal, the "Final Withdrawal Date"). If for any reason the Escrow Agent shall have failed to give the Final Withdrawal Notice to the Depositary on or before December 31, 2000 (provided, that if a labor strike or work stoppage occurs at The Boeing Company prior to such date, such date shall be extended by adding thereto the number of days that each such labor strike or work stoppage continues in effect), and there are unwithdrawn amounts in the Account (as defined in the Deposit Agreement) on such date, the Final Withdrawal Date shall be deemed to be January 16, 2001 (or, if the December 31, 2000 date has been extended as provided in this sentence, the fifteenth day after the Delivery Period Termination Date).

Section 1.03. Initial Escrow Amount; Issuance of Escrow Receipts. The Escrow Agent hereby directs the Placement Agents to, and the Placement Agents hereby acknowledge that on the date hereof they shall, irrevocably deliver to the Depositary on behalf of the Escrow Agent, an amount in U.S. dollars ("Dollars") and immediately available funds equal to $44,741,000 for deposit on behalf of the Escrow Agent with the Depositary in accordance with
Section 2.1 of the Deposit Agreement. The Placement Agents hereby instruct the Escrow Agent,

3

upon receipt of such sum from the Placement Agents, to confirm such receipt by executing and delivering to the Pass Through Trustee an Escrow Receipt in the form of Exhibit A hereto (an "Escrow Receipt"), (a) to be affixed by the Pass Through Trustee to each Certificate and (b) to evidence the same percentage interest (the "Escrow Interest") in the Account Amounts (as defined below) as the Fractional Undivided Interest in the Pass Through Trust evidenced by the Certificate to which it is to be affixed. The Escrow Agent shall provide to the Pass Through Trustee for attachment to each Certificate newly issued under and in accordance with the Pass Through Trust Agreement an executed Escrow Receipt as the Pass Through Trustee may from time to time request of the Escrow Agent. Each Escrow Receipt shall be registered by the Escrow Agent in a register (the "Register") maintained by the Escrow Agent in the same name and same manner as the Certificate to which it is attached and may not thereafter be detached from such Certificate to which it is to be affixed prior to the distribution of the Final Withdrawal (the "Final Distribution"). After the Final Distribution, no additional Escrow Receipts shall be issued and the Pass Through Trustee shall request the return to the Escrow Agent for cancellation of all outstanding Escrow Receipts.

Section 1.04. Payments to Receiptholders. All payments and distributions made to holders of an Escrow Receipt (collectively "Receiptholders") in respect of the Escrow Receipt shall be made only from amounts deposited in the Paying Agent Account (as defined below) ("Account Amounts"). Each Receiptholder, by its acceptance of an Escrow Receipt, agrees that (a) it will look solely to the Account Amounts for any payment or distribution due to such Receiptholder pursuant to the terms of the Escrow Receipt and this Agreement and (b) it will have no recourse to Atlas, the Pass Through Trustee, the Paying Agent or the Escrow Agent, except as expressly provided herein or in the Pass Through Trust Agreement. No Receiptholder shall have any right to vote or in any manner otherwise control the operation and management of the Paying Agent Account or the obligations of the parties hereto, nor shall anything set forth herein, or contained in the terms of the Escrow Receipt, be construed so as to constitute the Receiptholders from time to time as partners or members of an association.

Section 1.05. Mutilated, Destroyed, Lost or Stolen Escrow Receipt. If (a) any mutilated Escrow Receipt is surrendered to the Escrow Agent or the Escrow Agent receives evidence to its satisfaction of the destruction, loss or theft of any Escrow Receipt and (b) there is delivered to the Escrow Agent and the Pass Through Trustee such security, indemnity or bond, as may be required by them to hold each of them harmless, then, absent notice to the Escrow Agent or the Pass Through Trustee that such destroyed, lost or stolen Escrow Receipt has been acquired by a bona fide purchaser, and provided that the requirements of Section 8-405 of the Uniform Commercial Code in effect in any applicable jurisdiction are met, the Escrow Agent shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Escrow Receipt, a new Escrow Receipt or Escrow Receipts and of like Escrow Interest in the Account Amounts and bearing a number not contemporaneously outstanding.

In connection with the issuance of any new Escrow Receipt under this Section 1.05, the Escrow Agent may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Pass Through Trustee and the Escrow Agent) connected therewith.

4

Any duplicate Escrow Receipt issued pursuant to this Section 1.05 shall constitute conclusive evidence of the appropriate Escrow Interest in the Account Amounts, as if originally issued, whether or not the lost, stolen or destroyed Escrow Receipt shall be found at any time.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Escrow Receipts.

Section 1.06. Additional Escrow Amounts. On the date of any Purchase Withdrawal, the Pass Through Trustee may re-deposit with the Depositary some or all of the amounts so withdrawn in accordance with Section 2.4 of the Deposit Agreement.

Section 1.07. Resignation or Removal of Escrow Agent. Subject to the appointment and acceptance of a successor Escrow Agent as provided below, the Escrow Agent may resign at any time by giving 30 days' prior written notice thereof to the Investors, but may not otherwise be removed except for cause by the written consent of the Investors with respect to Investors representing Escrow Interests aggregating not less than a majority in interest in the Account Amounts (an "Action of Investors"). Upon any such resignation or removal, the Investors, by an Action of Investors, shall have the right to appoint a successor Escrow Agent. If no successor Escrow Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Escrow Agent's giving of notice of resignation or the removal of the retiring Escrow Agent, then the retiring Escrow Agent may appoint a successor Escrow Agent. Any successor Escrow Agent shall be a bank which has an office in the United States with a combined capital and surplus of at least $100,000,000. Upon the acceptance of any appointment as Escrow Agent hereunder by a successor Escrow Agent, such successor Escrow Agent shall enter into such documents as the Pass Through Trustee shall require and shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Escrow Agent, and the retiring Escrow Agent shall be discharged from its duties and obligations hereunder. No resignation or removal of the Escrow Agent shall be effective unless a written confirmation shall have been obtained from each of Moody's Investors Service, Inc. and Standard & Poor's Rating Group, a division of McGraw-Hill Inc. that the replacement of the Escrow Agent with the successor Escrow Agent will not result in (a) a reduction of the rating for the Certificates below the then current rating for the Certificates or (b) a withdrawal or suspension of the rating of the Certificates.

Section 1.08. Persons Deemed Owners. Prior to due presentment of a Certificate for registration of transfer, the Escrow Agent and the Paying Agent may treat the Person in whose name any Escrow Receipt is registered (as of the day of determination) as the owner of such Escrow Receipt for the purpose of receiving distributions pursuant to this Agreement and for all other purposes whatsoever, and neither the Escrow Agent nor the Paying Agent shall be affected by any notice to the contrary.

Section 1.09. Further Assurances. The Escrow Agent agrees to take such actions, and execute such other documents, as may be reasonably requested by the Pass Through

5

Trustee in order to effectuate the purposes of this Agreement and the performance by the Escrow Agent of its obligations hereunder.

SECTION 2. Paying Agent.

Section 2.01. Appointment of Paying Agent. The Escrow Agent hereby irrevocably appoints and authorizes the Paying Agent to act as its paying agent hereunder, for the benefit of the Investors, for such specific purposes and with such powers as are specifically delegated to the Paying Agent by the terms of this Agreement, together with such other powers as are reasonably incidental thereto. Any and all money received and held by the Paying Agent under this Agreement or the Deposit Agreement shall be held in the Paying Agent Account for the benefit of the Investors. The Paying Agent (which term as used in this sentence shall include reference to its affiliates and its own and its affiliates' officers, directors, employees and agents): (a) shall have no duties or responsibilities except those expressly set forth in this Agreement, and shall not by reason of this Agreement be a trustee for the Escrow Agent; (b) shall not be responsible to the Escrow Agent for any recitals, statements, representations or warranties of any person other then itself contained in this Agreement or for the failure by the Escrow Agent or any other person or entity (other than the Paying Agent) to perform any of its obligations hereunder
(whether or not the Paying Agent shall have any knowledge thereof); and (c)
shall not be responsible for any action taken or omitted to be taken by it hereunder or provided for herein or in connection herewith, except for its own willful misconduct or gross negligence (or simple negligence in connection with the handling of funds).

Section 2.02. Establishment of Paying Agent Account. The Paying Agent shall establish a deposit account (the "Paying Agent Account") at Wilmington Trust Company in the name of the Escrow Agent. It is expressly understood by the parties hereto that the Paying Agent is acting as the paying agent of the Escrow Agent hereunder and that no amounts on deposit in the Paying Agent Account constitute part of the Trust Property.

Section 2.03. Payments from Paying Agent Account. The Escrow Agent hereby irrevocably instructs the Paying Agent, and the Paying Agent agrees to act, as follows:

(a) On each Interest Payment Date (as defined in the Deposit Agreement) or as soon thereafter as the Paying Agent has confirmed receipt in the Paying Agent Account from the Depositary of any amount in respect of accrued interest on the Deposit, the Paying Agent shall distribute out of the Paying Agent Account the entire amount deposited therein by the Depositary. There shall be so distributed to each Receiptholder of record on the 15th day (whether or not a Business Day) preceding such Interest Payment Date by check mailed to such Receiptholder, at the address appearing in the Register, such Receiptholder's pro rata share (based on the Escrow Interest in the Account Amounts held by such Receiptholder) of the total amount of interest deposited by the Depositary in the Paying Agent Account on such date, except that, with respect to Escrow Receipts registered on the record date in the name of a nominee of the Depository Trust Company ("DTC"), such distribution shall be made by wire transfer in immediately available funds to the account designated by DTC.

6

(b) Upon the confirmation by the Paying Agent of receipt in the Paying Agent Account from the Depositary of any amount in respect of the Final Withdrawal, the Paying Agent shall forthwith distribute the entire amount of the Final Withdrawal deposited therein by the Depositary. There shall be so distributed to each Receiptholder of record on the 15th day (whether or not a Business Day) preceding the Final Withdrawal Date by check mailed to such Receiptholder, at the address appearing in the Register, such Receiptholder's pro rata share (based on the Escrow Interest in the Account Amounts held by such Receiptholder) of the total amount in the Paying Agent Account on account of such Final Withdrawal, except that, with respect to Escrow Receipts registered on the record date in the name of a nominee of DTC, such distribution shall be made by wire transfer in immediately available funds to the account designated by DTC.

(c) If any payment of interest or principal in respect of the Final Withdrawal is not received by the Paying Agent within five days of the applicable date when due, then it shall be distributed to Receiptholders after actual receipt by the Paying Agent on the same basis as a Special Payment is distributed under the Pass Through Trust Agreement.

(d) Upon the confirmation by the Paying Agent of receipt in the Paying Agent Account from the Depositary of any amount in respect of a Prepayment Withdrawal, the Paying Agent shall forthwith distribute the entire amount of such Prepayment Withdrawal upon not less than 15 days prior notice to the Receiptholders. There shall be distributed to each Receiptholder of record on the 15th day (whether or not a Business Day) preceding such date of distribution by check mailed to such Receiptholder, at the address appearing in the Register, such Receiptholder's pro rata share (based on the Escrow Interest in the Account Amounts held by such Receiptholder) of the total amount in the Paying Agent Account on account of such Prepayment Withdrawal, except that, with respect to the Escrow Receipts registered on such record date in the name of a nominee of DTC, such distribution shall be made by wire transfer in immediately available funds to the account designated by DTC.

(e) The Paying Agent shall include with any check mailed pursuant to this Section any notice required to be distributed under the Pass Through Trust Agreement that is furnished to the Paying Agent by the Pass Through Trustee.

Section 2.04. Withholding Taxes. The Paying Agent shall exclude and withhold from each distribution of accrued interest on the Deposit (as defined in the Deposit Agreement) and any amount in respect of any Prepayment Withdrawal and the Final Withdrawal any and all withholding taxes applicable thereto as required by law. The Paying Agent agrees to act as such withholding agent and, in connection therewith, whenever any present or future taxes or similar charges are required to be withheld with respect to any amounts payable in respect of the Deposit (as defined in the Deposit Agreement) or the escrow amounts, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of the Receiptholders, that it will file any necessary withholding tax returns or statements when due,

7

and that, as promptly as possible after the payment thereof, it will deliver to each such Receiptholder appropriate documentation showing the payment thereof, together with such additional documentary evidence as such Receiptholder may reasonably request from time to time. The Paying Agent agrees to file any other information reports as it may be required to file under United States law.

Section 2.05. Resignation or Removal of Paying Agent. Subject to the appointment and acceptance of a successor Paying Agent as provided below, the Paying Agent may resign at any time by giving 30 days' prior written notice thereof to the Escrow Agent, but may not otherwise be removed except for cause by the Escrow Agent. Upon any such resignation or removal, the Escrow Agent shall have the right to appoint a successor Paying Agent. If no successor Paying Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Paying Agent's giving of notice of resignation or the removal of the retiring Paying Agent, then the retiring Paying Agent may appoint a successor Paying Agent. Any Successor Paying Agent shall be a bank which has an office in the United States with a combined capital and surplus of at least $100,000,000. Upon the acceptance of any appointment as Paying Agent hereunder by a successor Paying Agent, such successor Paying Agent shall enter into such documents as the Escrow Agent shall require and shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Paying Agent, and the retiring Paying Agent shall be discharged from its duties and obligations hereunder.

Section 2.06. Notice of Prepayment Withdrawal and Final Withdrawal. Promptly after receipt by the Paying Agent of notice that the Escrow Agent has requested a Prepayment Withdrawal or a Final Withdrawal or that a Prepayment Withdrawal or a Final Withdrawal will be made, the Paying Agent shall cause notice of such distribution to be mailed to each of the Receiptholders at its address as it appears in the Register. Such notice shall be mailed not less than 15 days prior to the distribution date of such Prepayment Withdrawal (the "Prepayment Withdrawal Date") or of the Final Withdrawal Date, as the case may be. Such notice shall set forth:

(i) the Prepayment Withdrawal or the Final Withdrawal Date, as the case may be, and the date for determining Receiptholders of record who shall be entitled to receive distributions in respect of the Prepayment Withdrawal or Final Withdrawal,

(ii) the amount of the payment in respect of the Prepayment Withdrawal or Final Withdrawal, as the case may be, for each $1,000 face amount Certificate (based on information provided by the Pass Through Trustee) and the amount thereof constituting the unused portion of the Deposit (as defined in the Deposit Agreement) and interest thereon, and

(iii) if the Prepayment Withdrawal Date or Final Withdrawal Date is the same date as a Regular Distribution Date, the total amount to be received on such date for each $1,000 face amount Certificate (based on information provided by the Pass Through Trustee).

8

Such mailing may include any notice required to be given to Certificateholders in connection with such distribution pursuant to the Pass Through Trust Agreement.

SECTION 3. Payments. If, notwithstanding the instructions in
Section 4 of the Deposit Agreement that all amounts payable to the Escrow Agent under the Deposit Agreement be paid by the Depositary directly to the Paying Agent or the Pass Through Trustee (depending on the circumstances), the Escrow Agent receives any payment thereunder, then the Escrow Agent shall forthwith pay such amount in Dollars and in immediately available funds by wire transfer to
(a) in the case of a payment of accrued interest on the Deposit (as defined in the Deposit Agreement), any Prepayment Withdrawal or any Final Withdrawal, directly to the Paying Agent Account and (b) in the case of any Purchase Withdrawal, directly to the Pass Through Trustee or its designee as specified and in the manner provided in the Applicable Notice of Purchase Withdrawal. The Escrow Agent hereby waives any and all rights of set-off, combination of accounts, right of retention or similar right (whether arising under applicable law, contract or otherwise) it may have against amounts payable to the Paying Agent howsoever arising.

SECTION 4. Other Actions. The Escrow Agent shall take such other actions under or in respect of the Deposit Agreement (including, without limitation, the enforcement of the obligations of the Depositary thereunder) as the Investors, by an Action of Investors, may from time to time request.

This Escrow Receipt evidences a fractional undivided interest in amounts ("Account Amounts") from time to time deposited into a certain paying agent account (the "Paying Agent Account") described in the Escrow and Paying Agent Agreement (Class B) dated as of January 28, 2000 (as amended, modified or supplemented from time to time, the "Escrow and Paying Agent Agreement") among First Security Bank, National Association, as Escrow Agent (in such capacity, together with its successors in such capacity, the "Escrow Agent"), Morgan Stanley & Co. Incorporated, Deutsche Bank Securities Inc. and Salomon Smith Barney Inc., as Placement Agents, Wilmington Trust Company as Pass Through Trustee (in such capacity, together with its successors in such capacity, the "Pass Through Trustee") and Wilmington Trust Company, as paying agent (in such capacity, together with its successors in such capacity, the "Paying Agent"). Capitalized terms not defined herein shall have the meanings assigned to them in the Escrow and Paying Agent Agreement.

This Escrow Receipt is issued under and is subject to the terms, provisions and conditions of the Escrow and Paying Agent Agreement. By virtue of its acceptance hereof the holder of this Escrow Receipt assents and agrees to be bound by the provisions of the Escrow and Paying Agent Agreement and this Escrow Receipt.

This Escrow Receipt represents a fractional undivided interest in amounts deposited from time to time in the Paying Agent Account, and grants or represents no rights, benefits or interests of any kind in respect of any assets or property other than such amounts. This Escrow Receipt evidences the same percentage interest in the Account Amounts as the Fractional Undivided Interest in the Pass Through Trust evidenced by the Certificate to which this Escrow Receipt is affixed.

All payments and distributions made to Receiptholders in respect of the Escrow Receipt shall be made only from Account Amounts deposited in the Paying Agent Account. The holder of this Escrow Receipt, by its acceptance of this Escrow Receipt, agrees that it will look solely to the Account Amounts for any payment or distribution due to it pursuant to this Escrow Receipt and that it will not have any recourse to Atlas, the Pass Through Trustee, the Paying Agent or the Escrow Agent, except as expressly provided herein or in the Pass Through Trust Agreement.

the Pass Through Trustee, the holder hereof will return this Escrow Receipt to the Pass Through Trustee.

THIS ESCROW RECEIPT SHALL BE GOVERNED BY AND CONSTRUED IN

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

NOW, THEREFORE, in consideration of the obligations contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1. Escrow Agent.

Section 1.01. Appointment of Escrow Agent. Each of the Placement Agents, for and on behalf of each of the Investors, hereby irrevocably appoints, authorizes and directs the Escrow Agent to act as escrow agent and fiduciary hereunder and under the Deposit Agreement for such specific purposes and with such powers as are specifically delegated to the Escrow Agent by the terms of this Agreement, together with such other powers as are reasonably incidental thereto. Any and all money received and held by the Escrow Agent under this Agreement or the Deposit Agreement shall be held in escrow by the Escrow Agent in accordance with the terms of this Agreement. This Agreement is irrevocable and the Investors' rights with respect to any monies received and held in escrow by the Escrow Agent under this Agreement or the Deposit Agreement shall only be as provided under the terms and conditions of this Agreement and the Deposit Agreement. The Escrow Agent (which term as used in this sentence shall include reference to its affiliates and its own and its affiliates' officers, directors, employees and agents): (a) shall have no duties or responsibilities except those expressly set forth in this Agreement; (b) shall not be responsible to the Pass Through Trustee or the Investors for any recitals, statements, representations or warranties of any person other then itself contained in this Agreement or the Deposit Agreement or for the failure by the Pass Through Trustee, the Investors or any other person or entity (other than the Escrow Agent) to perform any of its obligations hereunder (whether or not the Escrow Agent shall have any knowledge thereof); and (c) shall not be responsible for any action taken or omitted to be taken by it hereunder or provided for herein or in connection herewith, except for its own willful misconduct or gross negligence (or simple negligence in connection with the handling of funds).

Section 1.02. Instruction; Etc. The Placement Agents, for and on behalf of each of the Investors, hereby irrevocably instruct the Escrow Agent, and the Escrow Agent agrees, (a) to enter into the Deposit Agreement, (b) to appoint the Paying Agent as provided in this Agreement, (c) upon receipt at any time and from time to time prior to the Delivery Period Termination Date (as defined in the Note Purchase Agreement) of a certificate substantially in


the form of Exhibit B hereto (a "Withdrawal Certificate") executed by the Pass Through Trustee, together with an attached Notice of Purchase Withdrawal in substantially the form of Exhibit A to the Deposit Agreement duly completed by the Pass Through Trustee (the "Applicable Notice of Purchase Withdrawal" and the withdrawal to which it relates, a "Purchase Withdrawal"), immediately to execute the Applicable Notice of Purchase Withdrawal as Escrow Agent and transmit it to the Depositary by facsimile transmission in accordance with the Deposit Agreement; provided that, upon the request of the Pass Through Trustee after such transmission, the Escrow Agent shall cancel such Applicable Notice of Purchase Withdrawal, (d) upon receipt at any time and from time to time prior to the Delivery Period Termination Date of a certificate substantially in the form of Exhibit C hereto (a "Prepayment Withdrawal Certificate") executed by the Pass Through Trustee, together with an attached Notice of Prepayment Withdrawal in substantially the form of Exhibit B to the Deposit Agreement duly completed by the Pass Through Trustee (the "Applicable Notice of Prepayment Withdrawal" and the withdrawal to which it relates, a "Prepayment Withdrawal"), immediately to execute the Applicable Notice of Prepayment Withdrawal as Escrow Agent and transmit it to the Depositary by facsimile transmission in accordance with the Deposit Agreement; provided that, upon the request of the Pass Through Trustee after such transmission, the Escrow Agent shall cancel such Applicable Notice of Prepayment Withdrawal, and (e) if there are any undrawn amounts in the Account (as defined in the Deposit Agreement) on the earlier of (i) the Delivery Period Termination Date and (ii) the date on which the Escrow Agent receives notice from the Pass Through Trustee that the Pass Through Trustee's obligation to purchase Equipment Notes under the Note Purchase Agreement has terminated, to give notice to the Depositary (with a copy to the Paying Agent) substantially in the form of Exhibit C to the Deposit Agreement requesting a withdrawal of all of the remaining amount of the Deposit (as defined in the Deposit Agreement), together with accrued and unpaid interest on the Deposit to the date of withdrawal, on the 15th day after the date that such notice of withdrawal is given to the Depositary (or, if not a Business Day, on the next succeeding Business Day) (a "Final Withdrawal"), provided that if the day scheduled for the Final Withdrawal in accordance with the foregoing is within 10 days before a Regular Distribution Date, then the Escrow Agent shall request that such requested Final Withdrawal be made on such Regular Distribution Date (the date of such requested withdrawal, the "Final Withdrawal Date"). If for any reason the Escrow Agent shall have failed to give the Final Withdrawal Notice to the Depositary on or before December 31, 2000 (provided, that if a labor strike or work stoppage occurs at The Boeing Company prior to such date, such date shall be extended by adding thereto the number of days that each such labor strike or work stoppage continues in effect), and there are unwithdrawn amounts in the Account (as defined in the Deposit Agreement) on such date, the Final Withdrawal Date shall be deemed to be January 16, 2001 (or, if the December 31, 2000 date has been extended as provided in this sentence, the fifteenth day after the Delivery Period Termination Date).

Section 1.03. Initial Escrow Amount; Issuance of Escrow Receipts. The Escrow Agent hereby directs the Placement Agents to, and the Placement Agents hereby acknowledge that on the date hereof they shall, irrevocably deliver to the Depositary on behalf of the Escrow Agent, an amount in U.S. dollars ("Dollars") and immediately available funds equal to $47,937,000 for deposit on behalf of the Escrow Agent with the Depositary in accordance with
Section 2.1 of the Deposit Agreement. The Placement Agents hereby instruct the Escrow Agent,


upon receipt of such sum from the Placement Agents, to confirm such receipt by executing and delivering to the Pass Through Trustee an Escrow Receipt in the form of Exhibit A hereto (an "Escrow Receipt"), (a) to be affixed by the Pass Through Trustee to each Certificate and (b) to evidence the same percentage interest (the "Escrow Interest") in the Account Amounts (as defined below) as the Fractional Undivided Interest in the Pass Through Trust evidenced by the Certificate to which it is to be affixed. The Escrow Agent shall provide to the Pass Through Trustee for attachment to each Certificate newly issued under and in accordance with the Pass Through Trust Agreement an executed Escrow Receipt as the Pass Through Trustee may from time to time request of the Escrow Agent. Each Escrow Receipt shall be registered by the Escrow Agent in a register (the "Register") maintained by the Escrow Agent in the same name and same manner as the Certificate to which it is attached and may not thereafter be detached from such Certificate to which it is to be affixed prior to the distribution of the Final Withdrawal (the "Final Distribution"). After the Final Distribution, no additional Escrow Receipts shall be issued and the Pass Through Trustee shall request the return to the Escrow Agent for cancellation of all outstanding Escrow Receipts.

Section 1.04. Payments to Receiptholders. All payments and distributions made to holders of an Escrow Receipt (collectively "Receiptholders") in respect of the Escrow Receipt shall be made only from amounts deposited in the Paying Agent Account (as defined below) ("Account Amounts"). Each Receiptholder, by its acceptance of an Escrow Receipt, agrees that (a) it will look solely to the Account Amounts for any payment or distribution due to such Receiptholder pursuant to the terms of the Escrow Receipt and this Agreement and (b) it will have no recourse to Atlas, the Pass Through Trustee, the Paying Agent or the Escrow Agent, except as expressly provided herein or in the Pass Through Trust Agreement. No Receiptholder shall have any right to vote or in any manner otherwise control the operation and management of the Paying Agent Account or the obligations of the parties hereto, nor shall anything set forth herein, or contained in the terms of the Escrow Receipt, be construed so as to constitute the Receiptholders from time to time as partners or members of an association.

Section 1.05. Mutilated, Destroyed, Lost or Stolen Escrow Receipt. If (a) any mutilated Escrow Receipt is surrendered to the Escrow Agent or the Escrow Agent receives evidence to its satisfaction of the destruction, loss or theft of any Escrow Receipt and (b) there is delivered to the Escrow Agent and the Pass Through Trustee such security, indemnity or bond, as may be required by them to hold each of them harmless, then, absent notice to the Escrow Agent or the Pass Through Trustee that such destroyed, lost or stolen Escrow Receipt has been acquired by a bona fide purchaser, and provided that the requirements of Section 8-405 of the Uniform Commercial Code in effect in any applicable jurisdiction are met, the Escrow Agent shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Escrow Receipt, a new Escrow Receipt or Escrow Receipts and of like Escrow Interest in the Account Amounts and bearing a number not contemporaneously outstanding.

In connection with the issuance of any new Escrow Receipt under this Section 1.05, the Escrow Agent may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Pass Through Trustee and the Escrow Agent) connected therewith.


Any duplicate Escrow Receipt issued pursuant to this Section 1.05 shall constitute conclusive evidence of the appropriate Escrow Interest in the Account Amounts, as if originally issued, whether or not the lost, stolen or destroyed Escrow Receipt shall be found at any time.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Escrow Receipts.

Section 1.06. Additional Escrow Amounts. On the date of any Purchase Withdrawal, the Pass Through Trustee may re-deposit with the Depositary some or all of the amounts so withdrawn in accordance with Section 2.4 of the Deposit Agreement.

Section 1.07. Resignation or Removal of Escrow Agent. Subject to the appointment and acceptance of a successor Escrow Agent as provided below, the Escrow Agent may resign at any time by giving 30 days' prior written notice thereof to the Investors, but may not otherwise be removed except for cause by the written consent of the Investors with respect to Investors representing Escrow Interests aggregating not less than a majority in interest in the Account Amounts (an "Action of Investors"). Upon any such resignation or removal, the Investors, by an Action of Investors, shall have the right to appoint a successor Escrow Agent. If no successor Escrow Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Escrow Agent's giving of notice of resignation or the removal of the retiring Escrow Agent, then the retiring Escrow Agent may appoint a successor Escrow Agent. Any successor Escrow Agent shall be a bank which has an office in the United States with a combined capital and surplus of at least $100,000,000. Upon the acceptance of any appointment as Escrow Agent hereunder by a successor Escrow Agent, such successor Escrow Agent shall enter into such documents as the Pass Through Trustee shall require and shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Escrow Agent, and the retiring Escrow Agent shall be discharged from its duties and obligations hereunder. No resignation or removal of the Escrow Agent shall be effective unless a written confirmation shall have been obtained from each of Moody's Investors Service, Inc. and Standard & Poor's Rating Group, a division of McGraw-Hill Inc. that the replacement of the Escrow Agent with the successor Escrow Agent will not result in (a) a reduction of the rating for the Certificates below the then current rating for the Certificates or (b) a withdrawal or suspension of the rating of the Certificates.

Section 1.08. Persons Deemed Owners. Prior to due presentment of a Certificate for registration of transfer, the Escrow Agent and the Paying Agent may treat the Person in whose name any Escrow Receipt is registered (as of the day of determination) as the owner of such Escrow Receipt for the purpose of receiving distributions pursuant to this Agreement and for all other purposes whatsoever, and neither the Escrow Agent nor the Paying Agent shall be affected by any notice to the contrary.

Section 1.09. Further Assurances. The Escrow Agent agrees to take such actions, and execute such other documents, as may be reasonably requested by the Pass Through


Trustee in order to effectuate the purposes of this Agreement and the performance by the Escrow Agent of its obligations hereunder.

SECTION 2. Paying Agent.

Section 2.01. Appointment of Paying Agent. The Escrow Agent hereby irrevocably appoints and authorizes the Paying Agent to act as its paying agent hereunder, for the benefit of the Investors, for such specific purposes and with such powers as are specifically delegated to the Paying Agent by the terms of this Agreement, together with such other powers as are reasonably incidental thereto. Any and all money received and held by the Paying Agent under this Agreement or the Deposit Agreement shall be held in the Paying Agent Account for the benefit of the Investors. The Paying Agent (which term as used in this sentence shall include reference to its affiliates and its own and its affiliates' officers, directors, employees and agents): (a) shall have no duties or responsibilities except those expressly set forth in this Agreement, and shall not by reason of this Agreement be a trustee for the Escrow Agent; (b) shall not be responsible to the Escrow Agent for any recitals, statements, representations or warranties of any person other then itself contained in this Agreement or for the failure by the Escrow Agent or any other person or entity (other than the Paying Agent) to perform any of its obligations hereunder
(whether or not the Paying Agent shall have any knowledge thereof); and (c)
shall not be responsible for any action taken or omitted to be taken by it hereunder or provided for herein or in connection herewith, except for its own willful misconduct or gross negligence (or simple negligence in connection with the handling of funds).

Section 2.02. Establishment of Paying Agent Account. The Paying Agent shall establish a deposit account (the "Paying Agent Account") at Wilmington Trust Company in the name of the Escrow Agent. It is expressly understood by the parties hereto that the Paying Agent is acting as the paying agent of the Escrow Agent hereunder and that no amounts on deposit in the Paying Agent Account constitute part of the Trust Property.

Section 2.03. Payments from Paying Agent Account. The Escrow Agent hereby irrevocably instructs the Paying Agent, and the Paying Agent agrees to act, as follows:

(a) On each Interest Payment Date (as defined in the Deposit Agreement) or as soon thereafter as the Paying Agent has confirmed receipt in the Paying Agent Account from the Depositary of any amount in respect of accrued interest on the Deposit, the Paying Agent shall distribute out of the Paying Agent Account the entire amount deposited therein by the Depositary. There shall be so distributed to each Receiptholder of record on the 15th day (whether or not a Business Day) preceding such Interest Payment Date by check mailed to such Receiptholder, at the address appearing in the Register, such Receiptholder's pro rata share (based on the Escrow Interest in the Account Amounts held by such Receiptholder) of the total amount of interest deposited by the Depositary in the Paying Agent Account on such date, except that, with respect to Escrow Receipts registered on the record date in the name of a nominee of the Depository Trust Company ("DTC"), such distribution shall be made by wire transfer in immediately available funds to the account designated by DTC.


(b) Upon the confirmation by the Paying Agent of receipt in the Paying Agent Account from the Depositary of any amount in respect of the Final Withdrawal, the Paying Agent shall forthwith distribute the entire amount of the Final Withdrawal deposited therein by the Depositary. There shall be so distributed to each Receiptholder of record on the 15th day (whether or not a Business Day) preceding the Final Withdrawal Date by check mailed to such Receiptholder, at the address appearing in the Register, such Receiptholder's pro rata share (based on the Escrow Interest in the Account Amounts held by such Receiptholder) of the total amount in the Paying Agent Account on account of such Final Withdrawal, except that, with respect to Escrow Receipts registered on the record date in the name of a nominee of DTC, such distribution shall be made by wire transfer in immediately available funds to the account designated by DTC.

(c) If any payment of interest or principal in respect of the Final Withdrawal is not received by the Paying Agent within five days of the applicable date when due, then it shall be distributed to Receiptholders after actual receipt by the Paying Agent on the same basis as a Special Payment is distributed under the Pass Through Trust Agreement.

(d) Upon the confirmation by the Paying Agent of receipt in the Paying Agent Account from the Depositary of any amount in respect of a Prepayment Withdrawal, the Paying Agent shall forthwith distribute the entire amount of such Prepayment Withdrawal upon not less than 15 days prior notice to the Receiptholders. There shall be distributed to each Receiptholder of record on the 15th day (whether or not a Business Day) preceding such date of distribution by check mailed to such Receiptholder, at the address appearing in the Register, such Receiptholder's pro rata share (based on the Escrow Interest in the Account Amounts held by such Receiptholder) of the total amount in the Paying Agent Account on account of such Prepayment Withdrawal, except that, with respect to the Escrow Receipts registered on such record date in the name of a nominee of DTC, such distribution shall be made by wire transfer in immediately available funds to the account designated by DTC.

(e) The Paying Agent shall include with any check mailed pursuant to this Section any notice required to be distributed under the Pass Through Trust Agreement that is furnished to the Paying Agent by the Pass Through Trustee.

Section 2.04. Withholding Taxes. The Paying Agent shall exclude and withhold from each distribution of accrued interest on the Deposit (as defined in the Deposit Agreement) and any amount in respect of any Prepayment Withdrawal and the Final Withdrawal any and all withholding taxes applicable thereto as required by law. The Paying Agent agrees to act as such withholding agent and, in connection therewith, whenever any present or future taxes or similar charges are required to be withheld with respect to any amounts payable in respect of the Deposit (as defined in the Deposit Agreement) or the escrow amounts, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of the Receiptholders, that it will file any necessary withholding tax returns or statements when due,


and that, as promptly as possible after the payment thereof, it will deliver to each such Receiptholder appropriate documentation showing the payment thereof, together with such additional documentary evidence as such Receiptholder may reasonably request from time to time. The Paying Agent agrees to file any other information reports as it may be required to file under United States law.

Section 2.05. Resignation or Removal of Paying Agent. Subject to the appointment and acceptance of a successor Paying Agent as provided below, the Paying Agent may resign at any time by giving 30 days' prior written notice thereof to the Escrow Agent, but may not otherwise be removed except for cause by the Escrow Agent. Upon any such resignation or removal, the Escrow Agent shall have the right to appoint a successor Paying Agent. If no successor Paying Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Paying Agent's giving of notice of resignation or the removal of the retiring Paying Agent, then the retiring Paying Agent may appoint a successor Paying Agent. Any Successor Paying Agent shall be a bank which has an office in the United States with a combined capital and surplus of at least $100,000,000. Upon the acceptance of any appointment as Paying Agent hereunder by a successor Paying Agent, such successor Paying Agent shall enter into such documents as the Escrow Agent shall require and shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Paying Agent, and the retiring Paying Agent shall be discharged from its duties and obligations hereunder.

Section 2.06. Notice of Prepayment Withdrawal and Final Withdrawal. Promptly after receipt by the Paying Agent of notice that the Escrow Agent has requested a Prepayment Withdrawal or a Final Withdrawal or that a Prepayment Withdrawal or a Final Withdrawal will be made, the Paying Agent shall cause notice of such distribution to be mailed to each of the Receiptholders at its address as it appears in the Register. Such notice shall be mailed not less than 15 days prior to the distribution date of such Prepayment Withdrawal (the "Prepayment Withdrawal Date") or of the Final Withdrawal Date, as the case may be. Such notice shall set forth:

(i) the Prepayment Withdrawal or the Final Withdrawal Date, as the case may be, and the date for determining Receiptholders of record who shall be entitled to receive distributions in respect of the Prepayment Withdrawal or Final Withdrawal,

(ii) the amount of the payment in respect of the Prepayment Withdrawal or Final Withdrawal, as the case may be, for each $1,000 face amount Certificate (based on information provided by the Pass Through Trustee) and the amount thereof constituting the unused portion of the Deposit (as defined in the Deposit Agreement) and interest thereon, and

(iii) if the Prepayment Withdrawal Date or Final Withdrawal Date is the same date as a Regular Distribution Date, the total amount to be received on such date for each $1,000 face amount Certificate (based on information provided by the Pass Through Trustee).


Such mailing may include any notice required to be given to Certificateholders in connection with such distribution pursuant to the Pass Through Trust Agreement.

SECTION 3. Payments. If, notwithstanding the instructions in
Section 4 of the Deposit Agreement that all amounts payable to the Escrow Agent under the Deposit Agreement be paid by the Depositary directly to the Paying Agent or the Pass Through Trustee (depending on the circumstances), the Escrow Agent receives any payment thereunder, then the Escrow Agent shall forthwith pay such amount in Dollars and in immediately available funds by wire transfer to
(a) in the case of a payment of accrued interest on the Deposit (as defined in the Deposit Agreement), any Prepayment Withdrawal or any Final Withdrawal, directly to the Paying Agent Account and (b) in the case of any Purchase Withdrawal, directly to the Pass Through Trustee or its designee as specified and in the manner provided in the Applicable Notice of Purchase Withdrawal. The Escrow Agent hereby waives any and all rights of set-off, combination of accounts, right of retention or similar right (whether arising under applicable law, contract or otherwise) it may have against amounts payable to the Paying Agent howsoever arising.

SECTION 4. Other Actions. The Escrow Agent shall take such other actions under or in respect of the Deposit Agreement (including, without limitation, the enforcement of the obligations of the Depositary thereunder) as the Investors, by an Action of Investors, may from time to time request.

(iv) no authorization, consent or approval of or other action by, and no notice to or filing with, any United States federal or state governmental authority or regulatory body governing its banking and fiduciary powers is required for the execution, delivery or performance by it of this Agreement or the Deposit Agreement;

(v) neither the execution, delivery or performance by it of this Agreement or the Deposit Agreement, nor compliance with the terms and provisions hereof or thereof, conflicts or will conflict with or results or will result in a breach or violation of any of the terms, conditions or provisions of, or will require any consent or approval under, any law, governmental rule or regulation or the charter documents, as amended, or bylaws, as amended, of it or any similar instrument binding on it or any order, writ, injunction or decree of any court or governmental authority against it or by which it or any of its properties is bound or any indenture, mortgage or contract or other agreement or instrument to which it is a party or by which it or any of its properties is bound, or constitutes or will constitute a default thereunder or results or will result in the imposition of any lien upon any of its properties; and

WHEREAS, the Escrow Agent, the Placement Agents, the Pass Through Trustee and Wilmington Trust Company, as paying agent for the Escrow Agent (in such capacity, together with its successors in such capacity, the "Paying Agent") concurrently herewith are entering into an Escrow and Paying Agent Agreement, dated as of the date hereof (as amended, modified or supplemented from time to time in accordance with the terms thereof, the "Escrow Agreement");

WHEREAS, Atlas and the Depositary concurrently herewith are entering into an Indemnity Agreement, dated as of the date hereof (the "Indemnity Agreement"); and

WHEREAS, the Placement Agents and the Pass Through Trustee intend that the Net Proceeds be held in escrow by the Escrow Agent on behalf of the Investors pursuant to the


Escrow Agreement, subject to withdrawal upon request of and proper certification by the Pass Through Trustee for the purpose of purchasing Equipment Notes, and that pending such withdrawal the Net Proceeds be deposited by the Escrow Agent with the Depositary pursuant to this Agreement, which provides for the Depositary to pay interest for distribution to the Investors and to establish an account from which the Escrow Agent shall make withdrawals upon request of and proper certification by the Pass Through Trustee.

NOW, THEREFORE, in consideration of the obligations contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1.1 Acceptance of Depositary. The Depositary hereby agrees to act as depositary bank as provided herein and in connection therewith to accept all amounts to be delivered to or held by the Depositary pursuant to the terms of this Agreement. The Depositary further agrees to hold, maintain and safeguard the Deposit and the Account (as defined below) during the term of this Agreement in accordance with the provisions of this Agreement. The Escrow Agent shall not have any right to withdraw, assign or otherwise transfer moneys held in the Account except as permitted by this Agreement.

SECTION 1.2 Establishment of Account. The Escrow Agent hereby instructs the Depositary, and the Depositary agrees, to establish the deposit account listed on Schedule I hereto (the "Account"), in the name of the Escrow Agent and on the terms and conditions set forth in this Agreement.

SECTION 2.1 Deposit. The Escrow Agent shall direct the Placement Agents to deposit with the Depositary on the date of this Agreement (the "Deposit Date") in Federal (same day) funds by wire transfer to: Westdeutsche Landesbank Girozentrale, New York Branch, Reference: Atlas 2000-1A, and the Depositary shall accept from the Placement Agents, on behalf of the Escrow Agent, the sum of US$124,639,000. Upon acceptance of such sum, the Depositary shall (i) establish the deposit specified in Schedule I hereto maturing on the date set forth therein (the "Deposit") and (ii) credit the Deposit to the Account as set forth therein. No amount shall be deposited in the Account other than the related Deposit.

SECTION 2.2 Interest. The Depositary shall pay interest on the balance of the Deposit from and including the date of deposit to but excluding the date of withdrawal at the rate of 8.707% per annum (computed on the basis of a year of twelve 30-day months) payable to the Paying Agent on behalf of the Escrow Agent semi-annually in arrears on each January 2 and July 2, commencing on July 2, 2000 (each, an "Interest Payment Date"), and on the date of each Prepayment Withdrawal and the Final Withdrawal (as defined below), all in accordance with the terms of this Agreement (whether or not any portion of the Deposit is withdrawn on an Interest Payment Date); provided, however, that in the event that no Registration Event (as defined in the Registration Rights Agreement) occurs on or prior to the 210th day after the date of the issuance of the Certificates (the "Registration Date"), the interest rate per annum paid by the Depositary on each Deposit shall be increased by 0.50%, effective from and including the 210th day after the date of issuance of the Certificates, to but excluding the date on which a Registration Event


occurs; and provided, further, that in the event that a Shelf Registration Statement (as defined in the Registration Rights Agreement) ceases to be effective for more than 60 days, whether or not consecutive, during any 12-month period at any time before the earlier of (a) the second anniversary of the effective date of the Shelf Registration Statement or (b) the sale pursuant to the Shelf Registration Statement of all the Certificates covered thereby, the interest rate per annum paid by the Depositary on each Deposit shall be increased by 0.50% per annum from the 61st day of the applicable 12-month period such Shelf Registration Statement ceases to be effective until such time as the Shelf Registration Statement again becomes effective. Interest accrued on any portion of the Deposit when withdrawn pursuant to a Notice of Purchase Withdrawal (as defined below) shall be paid on the next Interest Payment Date, notwithstanding any intervening Final Withdrawal.

SECTION 2.3 Withdrawals. (a) On and after the date seven days after the establishment of the Deposit, the Escrow Agent may, by providing at least one Business Day's prior notice of withdrawal to the Depositary in the form of Exhibit A hereto (a "Notice of Purchase Withdrawal"), withdraw all or a portion of the Deposit, except that at any time prior to the actual withdrawal of the Deposit, the Escrow Agent or the Pass Through Trustee may, by notice to the Depositary, cancel such withdrawal (including on the scheduled date therefor), and thereafter the Deposit shall continue to be maintained by the Depositary in accordance with the original terms thereof. Following such withdrawal the balance in the Account shall be reduced by the amount of the withdrawal. As used herein, "Business Day" means any day, other than a Saturday, Sunday or other day on which commercial banks are authorized or required by law to close in New York, New York, Denver, Colorado, Salt Lake City, Utah or Wilmington, Delaware. If a Notice of Purchase Withdrawal is related to a single aircraft, the amount of withdrawal specified therein shall not exceed the maximum principal amount of the Equipment Notes for such aircraft, as specified in the Offering Memorandum (as defined in the Note Purchase Agreement).

(b) The Escrow Agent may, by providing at least 15 days' prior notice of withdrawal to the Depositary in the form of Exhibit B hereto (a "Notice of Prepayment Withdrawal"), withdraw all or a portion of the Deposit together with all accrued and unpaid interest thereon to but excluding the specified date of withdrawal (a "Prepayment Withdrawal"), on such date as shall be specified in such Notice of Prepayment Withdrawal. Following such withdrawal the balance in the Account shall be reduced by the amount of the withdrawal. Upon any Prepayment Withdrawal, the Depositary shall pay to the Paying Agent the amount requested in the related Notice of Prepayment Withdrawal, provided that after giving pro forma effect to any Prepayment Withdrawal, the remaining amount of the Deposit shall not be less than the maximum principal amount of the Equipment Notes issuable in respect of any aircraft scheduled to be delivered after the date of such Prepayment Withdrawal, as specified in the Offering Memorandum.

(c) The Escrow Agent may, by providing at least 15 days' prior notice of withdrawal to the Depositary in the form of Exhibit C hereto (a "Notice of Final Withdrawal"), withdraw the entire amount of the Deposit together with the all accrued and unpaid interest on the Deposit to but excluding the specified date of withdrawal (a "Final Withdrawal"), on such


date as shall be specified in such Notice of Final Withdrawal. Following such withdrawal the balance in the Account shall be zero and the Depositary shall close such Account. If a Notice of Final Withdrawal has not been given to the Depositary on or before December 31, 2000 (provided that if a labor strike or work stoppage occurs at The Boeing Company prior to such date, such date shall be extended by adding thereto the number of days that each such labor strike or work stoppage continues in effect) and there are unwithdrawn amounts in the Account on such date, the Depositary shall pay the amount of the Final Withdrawal to the Paying Agent on January 16, 2001 (or if the December 31, 2000 date has been extended as set forth in this sentence, the fifteenth day after the Delivery Period Termination Date).

(d) If the Depositary receives a duly completed Notice of Purchase Withdrawal, Notice of Prepayment Withdrawal or Notice of Final Withdrawal complying with the provisions of this Agreement, it shall make the payments specified therein in accordance with the provisions of this Agreement. No notice of withdrawal shall be given within seven days after the date of the immediately preceding notice of withdrawal.

SECTION 2.4 Re-Deposit. On the date of withdrawal of any portion of the Deposit, the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow Agent, shall be entitled to re-deposit with the Depositary any portion thereof and the Depositary shall accept the same for deposit hereunder. Any sums so received for deposit shall be deemed not to have been withdrawn for all purposes hereof.

SECTION 3.1 Termination. This Agreement shall terminate on the later of the date on which (i) all of the Deposit shall have been withdrawn and paid as provided herein without any re-deposit and (ii) all accrued and unpaid interest on the Deposit shall have been paid as provided herein, but in no event prior to the date on which the Depositary shall have performed in full its obligations hereunder.

SECTION 4. Payments. All payments (including, without limitation, those payments made in respect of Taxes (as defined and provided for below)) made by the Depositary hereunder shall be paid in United States Dollars and immediately available funds by wire transfer (i) in the case of accrued interest on the Deposit payable under Section 2.2 hereof, any Prepayment Withdrawal or any Final Withdrawal, directly to the Paying Agent at Wilmington Trust Company, Wilmington, Delaware, ABA #03-11-000-92, Account No. 50849-0, Attention: Robert Hines, Reference: Atlas Air 2000-1A, or to such other account as the Paying Agent may direct from time to time in writing to the Depositary and the Escrow Agent and (ii) in the case of any withdrawal of all or a portion of the Deposit pursuant to a Notice of Purchase Withdrawal, directly to or as directed by the Pass Through Trustee as specified and in the manner provided in such Notice of Purchase Withdrawal. The Depositary hereby waives any and all rights of set-off, combination of accounts, right of retention or similar right (whether arising under applicable law, contract or otherwise) it may have against the Deposit howsoever arising. All payments on or in respect of the Deposit shall be made free and clear of and without reduction for or on account of any and all taxes, levies or other impositions or charges (collectively, "Taxes"). However, if the Depositary or the Paying Agent (pursuant to Section 2.04 of the Escrow Agreement) shall be required by law to deduct or withhold any Taxes from or


in respect of any sum payable hereunder, the Depositary shall (i) make such deductions or withholding, (ii) pay the full amount deducted or withheld (including in respect of such additional amounts) to the competent taxation authority and (iii) if the Taxes required to be deducted or withheld are imposed by the Federal Republic of Germany or any political subdivision thereof, pay such additional amounts as may be necessary in order that the actual amount received by the designated recipient of such sum under this Agreement or the Escrow Agreement after such deduction or withholding equals the sum it would have received had no such deduction or withholding been required. If the date on which any payment due on the Deposit would otherwise fall on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day, with the same force and effect as if made on such scheduled date, and no additional interest shall accrue in respect of such extension.

SECTION 5. Representation and Warranties. The Depositary hereby represents and warrants to Atlas, the Escrow Agent, the Pass Through Trustee and the Paying Agent that:

(a) it is duly organized and validly existing as a German public law banking institution under the laws of the State of Rhine-Westphalia and is duly qualified to conduct banking business in the State of New York through its New York Branch;

(f) there are no pending or, to its knowledge, threatened actions, suits, investigations or proceedings (whether or not purportedly on behalf of it) against or affecting it or any of its property before or by any court or administrative agency which, if adversely determined, (i) would adversely affect the ability of it to perform its obligations under this Agreement or (ii) would call into question or challenge the validity of this Agreement or the enforceability hereof in accordance with the terms hereof, nor is the Depositary in default with respect to any order of any court, governmental authority, arbitration board or administrative agency so as to adversely affect its ability to perform its obligations under this Agreement; and

(g) the Depositary will make all payments under this Agreement from its own funds and not from funds provided by, or on deposit from, Atlas or any of Atlas' subsidiaries.

SECTION 6. Transfer. Neither party hereto shall be entitled to assign or otherwise transfer this Agreement (or any interest herein) other than (in the case of the Escrow Agent) to a successor escrow agent under the Escrow Agreement, and any purported assignment in violation thereof shall be void. This Agreement shall be binding upon the parties hereto and their respective successors and (in the case of the Escrow Agent) permitted assigns.

and

Westdeutsche Landesbank Girozentrale,
New York Branch,

as Depositary


DEPOSIT AGREEMENT (Class B) dated as of January 28, 2000 (as amended, modified or supplemented from time to time, this "Agreement") between First Security Bank, National Association, a national banking association, as Escrow Agent under the Escrow and Paying Agent Agreement referred to below (in such capacity, together with its successors in such capacity, the "Escrow Agent"), and WESTDEUTSCHE LANDESBANK GIROZENTRALE, a German banking institution organized under the laws of the State of North Rhine-Westphalia, acting through its New York Branch as depositary bank (the "Depositary").

W I T N E S S E T H

WHEREAS, Atlas Air, Inc. ("Atlas") and Wilmington Trust Company, not in its individual capacity except as otherwise expressly provided therein, but solely as trustee (in such capacity, together with its successors in such capacity, the "Pass Through Trustee") have entered into a Trust Supplement, dated the date hereof to the Pass Through Trust Agreement dated as of January 28, 2000 (together, as amended, modified or supplemented from time to time in accordance with the terms thereof, the "Pass Through Trust Agreement") relating to Atlas Air Pass Through Trust 2000-1B pursuant to which the Atlas Air Pass Through Trust, Series 2000-1B Certificates referred to therein (the "Certificates") are being issued;

WHEREAS, Atlas and Morgan Stanley & Co. Incorporated, Deutsche Bank Securities Inc. and Salomon Smith Barney Inc. (collectively, the "Placement Agents" and, together with their respective transferees and assigns as registered owners of the Certificates, the "Investors") have entered into a Placement Agreement dated January 20, 2000 pursuant to which the Pass Through Trustee will issue and sell the Certificates to the Placement Agents;

WHEREAS, Atlas, the Pass Through Trustee, certain other pass through trustees and certain other persons concurrently herewith are entering into the Note Purchase Agreement, dated as of the date hereof (the "Note Purchase Agreement"), pursuant to which the Pass Through Trustee has agreed to acquire, subject to the terms thereof, from time to time on or prior to the Delivery Period Termination Date (as defined in the Note Purchase Agreement) equipment notes (the "Equipment Notes") issued to finance the acquisition of aircraft by Atlas, as lessee or as owner, utilizing a portion of the proceeds from the sale of the Certificates (the "Net Proceeds");

WHEREAS, the Escrow Agent, the Placement Agents, the Pass Through Trustee and Wilmington Trust Company, as paying agent for the Escrow Agent (in such capacity, together with its successors in such capacity, the "Paying Agent") concurrently herewith are entering into an Escrow and Paying Agent Agreement, dated as of the date hereof (as amended, modified or supplemented from time to time in accordance with the terms thereof, the "Escrow Agreement");

WHEREAS, Atlas and the Depositary concurrently herewith are entering into an Indemnity Agreement, dated as of the date hereof (the "Indemnity Agreement"); and


WHEREAS, the Placement Agents and the Pass Through Trustee intend that the Net Proceeds be held in escrow by the Escrow Agent on behalf of the Investors pursuant to the Escrow Agreement, subject to withdrawal upon request of and proper certification by the Pass Through Trustee for the purpose of purchasing Equipment Notes, and that pending such withdrawal the Net Proceeds be deposited by the Escrow Agent with the Depositary pursuant to this Agreement, which provides for the Depositary to pay interest for distribution to the Investors and to establish an account from which the Escrow Agent shall make withdrawals upon request of and proper certification by the Pass Through Trustee.

NOW, THEREFORE, in consideration of the obligations contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1.1 Acceptance of Depositary. The Depositary hereby agrees to act as depositary bank as provided herein and in connection therewith to accept all amounts to be delivered to or held by the Depositary pursuant to the terms of this Agreement. The Depositary further agrees to hold, maintain and safeguard the Deposit and the Account (as defined below) during the term of this Agreement in accordance with the provisions of this Agreement. The Escrow Agent shall not have any right to withdraw, assign or otherwise transfer moneys held in the Account except as permitted by this Agreement.

SECTION 1.2 Establishment of Account. The Escrow Agent hereby instructs the Depositary, and the Depositary agrees, to establish the deposit account listed on Schedule I hereto (the "Account"), in the name of the Escrow Agent and on the terms and conditions set forth in this Agreement.

SECTION 2.1 Deposit. The Escrow Agent shall direct the Placement Agents to deposit with the Depositary on the date of this Agreement (the "Deposit Date") in Federal (same day) funds by wire transfer to:
Westdeutsche Landesbank Girozentrale, New York Branch, Reference: Atlas 2000-1B, and the Depositary shall accept from the Placement Agents, on behalf of the Escrow Agent, the sum of US$44,741,000. Upon acceptance of such sum, the Depositary shall (i) establish the deposit specified in Schedule I hereto maturing on the date set forth therein (the "Deposit") and (ii) credit the Deposit to the Account as set forth therein. No amount shall be deposited in the Account other than the related Deposit.

SECTION 2.2 Interest. The Depositary shall pay interest on the balance of the Deposit from and including the date of deposit to but excluding the date of withdrawal at the rate of 9.057% per annum (computed on the basis of a year of twelve 30-day months) payable to the Paying Agent on behalf of the Escrow Agent semi-annually in arrears on each January 2 and July 2, commencing on July 2, 2000 (each, an "Interest Payment Date"), and on the date of each Prepayment Withdrawal and the Final Withdrawal (as defined below), all in accordance with the terms of this Agreement (whether or not any portion of the Deposit is withdrawn on an Interest Payment Date); provided, however, that in the event that no Registration Event (as defined in the Registration Rights Agreement) occurs on or prior to the 210th day after the date of the issuance of the Certificates (the "Registration Date"), the interest rate per annum paid by the Depositary


on each Deposit shall be increased by 0.50%, effective from and including the 210th day after the date of issuance of the Certificates, to but excluding the date on which a Registration Event occurs; and provided, further, that in the event that a Shelf Registration Statement (as defined in the Registration Rights Agreement) ceases to be effective for more than 60 days, whether or not consecutive, during any 12-month period at any time before the earlier of (a) the second anniversary of the effective date of the Shelf Registration Statement or (b) the sale pursuant to the Shelf Registration Statement of all the Certificates covered thereby, the interest rate per annum paid by the Depositary on each Deposit shall be increased by 0.50% per annum from the 61st day of the applicable 12-month period such Shelf Registration Statement ceases to be effective until such time as the Shelf Registration Statement again becomes effective. Interest accrued on any portion of the Deposit when withdrawn pursuant to a Notice of Purchase Withdrawal (as defined below) shall be paid on the next Interest Payment Date, notwithstanding any intervening Final Withdrawal.

SECTION 2.3 Withdrawals. (a) On and after the date seven days after the establishment of the Deposit, the Escrow Agent may, by providing at least one Business Day's prior notice of withdrawal to the Depositary in the form of Exhibit A hereto (a "Notice of Purchase Withdrawal"), withdraw all or a portion of the Deposit, except that at any time prior to the actual withdrawal of the Deposit, the Escrow Agent or the Pass Through Trustee may, by notice to the Depositary, cancel such withdrawal (including on the scheduled date therefor), and thereafter the Deposit shall continue to be maintained by the Depositary in accordance with the original terms thereof. Following such withdrawal the balance in the Account shall be reduced by the amount of the withdrawal. As used herein, "Business Day" means any day, other than a Saturday, Sunday or other day on which commercial banks are authorized or required by law to close in New York, New York, Denver, Colorado, Salt Lake City, Utah or Wilmington, Delaware. If a Notice of Purchase Withdrawal is related to a single aircraft, the amount of withdrawal specified therein shall not exceed the maximum principal amount of the Equipment Notes for such aircraft, as specified in the Offering Memorandum (as defined in the Note Purchase Agreement).

(b) The Escrow Agent may, by providing at least 15 days' prior notice of withdrawal to the Depositary in the form of Exhibit B hereto (a "Notice of Prepayment Withdrawal"), withdraw all or a portion of the Deposit together with all accrued and unpaid interest thereon to but excluding the specified date of withdrawal (a "Prepayment Withdrawal"), on such date as shall be specified in such Notice of Prepayment Withdrawal. Following such withdrawal the balance in the Account shall be reduced by the amount of the withdrawal. Upon any Prepayment Withdrawal, the Depositary shall pay to the Paying Agent the amount requested in the related Notice of Prepayment Withdrawal, provided that after giving pro forma effect to any Prepayment Withdrawal, the remaining amount of the Deposit shall not be less than the maximum principal amount of the Equipment Notes issuable in respect of any aircraft scheduled to be delivered after the date of such Prepayment Withdrawal, as specified in the Offering Memorandum.

(c) The Escrow Agent may, by providing at least 15 days' prior notice of withdrawal to the Depositary in the form of Exhibit C hereto (a "Notice of Final Withdrawal"),


withdraw the entire amount of the Deposit together with the all accrued and unpaid interest on the Deposit to but excluding the specified date of withdrawal (a "Final Withdrawal"), on such date as shall be specified in such Notice of Final Withdrawal. Following such withdrawal the balance in the Account shall be zero and the Depositary shall close such Account. If a Notice of Final Withdrawal has not been given to the Depositary on or before December 31, 2000 (provided that if a labor strike or work stoppage occurs at The Boeing Company prior to such date, such date shall be extended by adding thereto the number of days that each such labor strike or work stoppage continues in effect) and there are unwithdrawn amounts in the Account on such date, the Depositary shall pay the amount of the Final Withdrawal to the Paying Agent on January 16, 2001 (or if the December 31, 2000 date has been extended as set forth in this sentence, the fifteenth day after the Delivery Period Termination Date).

(d) If the Depositary receives a duly completed Notice of Purchase Withdrawal, Notice of Prepayment Withdrawal or Notice of Final Withdrawal complying with the provisions of this Agreement, it shall make the payments specified therein in accordance with the provisions of this Agreement. No notice of withdrawal shall be given within seven days after the date of the immediately preceding notice of withdrawal.

SECTION 2.4 Re-Deposit. On the date of withdrawal of any portion of the Deposit, the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow Agent, shall be entitled to re-deposit with the Depositary any portion thereof and the Depositary shall accept the same for deposit hereunder. Any sums so received for deposit shall be deemed not to have been withdrawn for all purposes hereof.

SECTION 3.1 Termination. This Agreement shall terminate on the later of the date on which (i) all of the Deposit shall have been withdrawn and paid as provided herein without any re-deposit and (ii) all accrued and unpaid interest on the Deposit shall have been paid as provided herein, but in no event prior to the date on which the Depositary shall have performed in full its obligations hereunder.

SECTION 4. Payments. All payments (including, without limitation, those payments made in respect of Taxes (as defined and provided for below)) made by the Depositary hereunder shall be paid in United States Dollars and immediately available funds by wire transfer (i) in the case of accrued interest on the Deposit payable under Section 2.2 hereof, any Prepayment Withdrawal or any Final Withdrawal, directly to the Paying Agent at Wilmington Trust Company, Wilmington, Delaware, ABA # 03-11-000-92, Account No. 50849-0, Attention: Robert Hines, Reference: Atlas Air 2000-1B, or to such other account as the Paying Agent may direct from time to time in writing to the Depositary and the Escrow Agent and (ii) in the case of any withdrawal of all or a portion of the Deposit pursuant to a Notice of Purchase Withdrawal, directly to or as directed by the Pass Through Trustee as specified and in the manner provided in such Notice of Purchase Withdrawal. The Depositary hereby waives any and all rights of set-off, combination of accounts, right of retention or similar right (whether arising under applicable law, contract or otherwise) it may have against the Deposit howsoever arising. All payments on or in respect of the Deposit shall be made free and clear of and without reduction for or on account of any and all taxes, levies or other impositions or charges


(collectively, "Taxes"). However, if the Depositary or the Paying Agent (pursuant to Section 2.04 of the Escrow Agreement) shall be required by law to deduct or withhold any Taxes from or in respect of any sum payable hereunder, the Depositary shall (i) make such deductions or withholding, (ii) pay the full amount deducted or withheld (including in respect of such additional amounts) to the competent taxation authority and (iii) if the Taxes required to be deducted or withheld are imposed by the Federal Republic of Germany or any political subdivision thereof, pay such additional amounts as may be necessary in order that the actual amount received by the designated recipient of such sum under this Agreement or the Escrow Agreement after such deduction or withholding equals the sum it would have received had no such deduction or withholding been required. If the date on which any payment due on the Deposit would otherwise fall on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day, with the same force and effect as if made on such scheduled date, and no additional interest shall accrue in respect of such extension.

SECTION 5. Representation and Warranties. The Depositary hereby represents and warrants to Atlas, the Escrow Agent, the Pass Through Trustee and the Paying Agent that:

(a) it is duly organized and validly existing as a German public law banking institution under the laws of the State of Rhine-Westphalia and is duly qualified to conduct banking business in the State of New York through its New York Branch;

(b) it has full power, authority and legal right to conduct its business and operations as currently conducted and to enter into and perform its obligations under this Agreement;

(d) no authorization, consent or approval of or other action by, and no notice to or filing with, any United States federal or state governmental authority or regulatory body is required for the execution, delivery or performance by it of this Agreement;

(e) neither the execution, delivery or performance by it of this Agreement, nor compliance with the terms and provisions hereof, conflicts or will conflict with or results or will result in a breach or violation of any of the terms, conditions or provisions of, or will require any consent or approval under, any law, governmental rule or regulation or the charter documents, as amended, or bylaws, as amended, of it or any similar instrument binding on it or any order, writ, injunction or decree of any court or governmental authority against it or by which it or any of its properties is bound or any indenture, mortgage or contract or other agreement or instrument to which it is a party or


by which it or any of its properties is bound, or constitutes or will constitute a default thereunder or results or will result in the imposition of any lien upon any of its properties;

(f) there are no pending or, to its knowledge, threatened actions, suits, investigations or proceedings (whether or not purportedly on behalf of it) against or affecting it or any of its property before or by any court or administrative agency which, if adversely determined, (i) would adversely affect the ability of it to perform its obligations under this Agreement or (ii) would call into question or challenge the validity of this Agreement or the enforceability hereof in accordance with the terms hereof, nor is the Depositary in default with respect to any order of any court, governmental authority, arbitration board or administrative agency so as to adversely affect its ability to perform its obligations under this Agreement; and

(g) the Depositary will make all payments under this Agreement from its own funds and not from funds provided by, or on deposit from, Atlas or any of Atlas' subsidiaries.

SECTION 6. Transfer. Neither party hereto shall be entitled to assign or otherwise transfer this Agreement (or any interest herein) other than (in the case of the Escrow Agent) to a successor escrow agent under the Escrow Agreement, and any purported assignment in violation thereof shall be void. This Agreement shall be binding upon the parties hereto and their respective successors and (in the case of the Escrow Agent) permitted assigns.

NOW, THEREFORE, in consideration of the obligations contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1.1 Acceptance of Depositary. The Depositary hereby agrees to act as depositary bank as provided herein and in connection therewith to accept all amounts to be delivered to or held by the Depositary pursuant to the terms of this Agreement. The Depositary further agrees to hold, maintain and safeguard the Deposit and the Account (as defined below) during the term of this Agreement in accordance with the provisions of this Agreement. The Escrow Agent shall not have any right to withdraw, assign or otherwise transfer moneys held in the Account except as permitted by this Agreement.

SECTION 1.2 Establishment of Account. The Escrow Agent hereby instructs the Depositary, and the Depositary agrees, to establish the deposit account listed on Schedule I hereto (the "Account"), in the name of the Escrow Agent and on the terms and conditions set forth in this Agreement.

SECTION 2.1 Deposit. The Escrow Agent shall direct the Placement Agents to deposit with the Depositary on the date of this Agreement (the "Deposit Date") in Federal (same day) funds by wire transfer to:
Westdeutsche Landesbank Girozentrale, New York Branch, Reference: Atlas 2000-1C, and the Depositary shall accept from the Placement Agents, on behalf of the Escrow Agent, the sum of US$47,937,000. Upon acceptance of such sum, the Depositary shall (i) establish the deposit specified in Schedule I hereto maturing on the date set forth therein (the "Deposit") and (ii) credit the Deposit to the Account as set forth therein. No amount shall be deposited in the Account other than the related Deposit.

SECTION 2.2 Interest. The Depositary shall pay interest on the balance of the Deposit from and including the date of deposit to but excluding the date of withdrawal at the rate of 9.702% per annum (computed on the basis of a year of twelve 30-day months) payable to the Paying Agent on behalf of the Escrow Agent semi-annually in arrears on each January 2 and July 2, commencing on July 2, 2000 (each, an "Interest Payment Date"), and on the date of each Prepayment Withdrawal and the Final Withdrawal (as defined below), all in accordance with the terms of this Agreement (whether or not any portion of the Deposit is withdrawn on an Interest Payment Date); provided, however, that in the event that no Registration Event (as defined in the Registration Rights Agreement) occurs on or prior to the 210th day after the date of the issuance of the Certificates (the "Registration Date"), the interest rate per annum paid by the Depositary on each Deposit shall be increased by 0.50%, effective from and including the 210th day after the date of issuance of the Certificates, to but excluding the date on which a Registration Event


occurs; and provided, further, that in the event that a Shelf Registration Statement (as defined in the Registration Rights Agreement) ceases to be effective for more than 60 days, whether or not consecutive, during any 12-month period at any time before the earlier of (a) the second anniversary of the effective date of the Shelf Registration Statement or (b) the sale pursuant to the Shelf Registration Statement of all the Certificates covered thereby, the interest rate per annum paid by the Depositary on each Deposit shall be increased by 0.50% per annum from the 61st day of the applicable 12-month period such Shelf Registration Statement ceases to be effective until such time as the Shelf Registration Statement again becomes effective. Interest accrued on any portion of the Deposit when withdrawn pursuant to a Notice of Purchase Withdrawal (as defined below) shall be paid on the next Interest Payment Date, notwithstanding any intervening Final Withdrawal.

SECTION 2.3 Withdrawals. (a) On and after the date seven days after the establishment of the Deposit, the Escrow Agent may, by providing at least one Business Day's prior notice of withdrawal to the Depositary in the form of Exhibit A hereto (a "Notice of Purchase Withdrawal"), withdraw all or a portion of the Deposit, except that at any time prior to the actual withdrawal of the Deposit, the Escrow Agent or the Pass Through Trustee may, by notice to the Depositary, cancel such withdrawal (including on the scheduled date therefor), and thereafter the Deposit shall continue to be maintained by the Depositary in accordance with the original terms thereof. Following such withdrawal the balance in the Account shall be reduced by the amount of the withdrawal. As used herein, "Business Day" means any day, other than a Saturday, Sunday or other day on which commercial banks are authorized or required by law to close in New York, New York, Denver, Colorado, Salt Lake City, Utah or Wilmington, Delaware. If a Notice of Purchase Withdrawal is related to a single aircraft, the amount of withdrawal specified therein shall not exceed the maximum principal amount of the Equipment Notes for such aircraft, as specified in the Offering Memorandum (as defined in the Note Purchase Agreement).

(b) The Escrow Agent may, by providing at least 15 days' prior notice of withdrawal to the Depositary in the form of Exhibit B hereto (a "Notice of Prepayment Withdrawal"), withdraw all or a portion of the Deposit together with all accrued and unpaid interest thereon to but excluding the specified date of withdrawal (a "Prepayment Withdrawal"), on such date as shall be specified in such Notice of Prepayment Withdrawal. Following such withdrawal the balance in the Account shall be reduced by the amount of the withdrawal. Upon any Prepayment Withdrawal, the Depositary shall pay to the Paying Agent the amount requested in the related Notice of Prepayment Withdrawal, provided that after giving pro forma effect to any Prepayment Withdrawal, the remaining amount of the Deposit shall not be less than the maximum principal amount of the Equipment Notes issuable in respect of any aircraft scheduled to be delivered after the date of such Prepayment Withdrawal, as specified in the Offering Memorandum.

(c) The Escrow Agent may, by providing at least 15 days' prior notice of withdrawal to the Depositary in the form of Exhibit C hereto (a "Notice of Final Withdrawal"), withdraw the entire amount of the Deposit together with the all accrued and unpaid interest on the Deposit to but excluding the specified date of withdrawal (a "Final Withdrawal"), on such


date as shall be specified in such Notice of Final Withdrawal. Following such withdrawal the balance in the Account shall be zero and the Depositary shall close such Account. If a Notice of Final Withdrawal has not been given to the Depositary on or before December 31, 2000 (provided that if a labor strike or work stoppage occurs at The Boeing Company prior to such date, such date shall be extended by adding thereto the number of days that each such labor strike or work stoppage continues in effect) and there are unwithdrawn amounts in the Account on such date, the Depositary shall pay the amount of the Final Withdrawal to the Paying Agent on January 16, 2001 (or if the December 31, 2000 date has been extended as set forth in this sentence, the fifteenth day after the Delivery Period Termination Date).

(d) If the Depositary receives a duly completed Notice of Purchase Withdrawal, Notice of Prepayment Withdrawal or Notice of Final Withdrawal complying with the provisions of this Agreement, it shall make the payments specified therein in accordance with the provisions of this Agreement. No notice of withdrawal shall be given within seven days after the date of the immediately preceding notice of withdrawal.

SECTION 2.4 Re-Deposit. On the date of withdrawal of any portion of the Deposit, the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow Agent, shall be entitled to re-deposit with the Depositary any portion thereof and the Depositary shall accept the same for deposit hereunder. Any sums so received for deposit shall be deemed not to have been withdrawn for all purposes hereof.

SECTION 3.1 Termination. This Agreement shall terminate on the later of the date on which (i) all of the Deposit shall have been withdrawn and paid as provided herein without any re-deposit and (ii) all accrued and unpaid interest on the Deposit shall have been paid as provided herein, but in no event prior to the date on which the Depositary shall have performed in full its obligations hereunder.

SECTION 4. Payments. All payments (including, without limitation, those payments made in respect of Taxes (as defined and provided for below)) made by the Depositary hereunder shall be paid in United States Dollars and immediately available funds by wire transfer (i) in the case of accrued interest on the Deposit payable under Section 2.2 hereof, any Prepayment Withdrawal or any Final Withdrawal, directly to the Paying Agent at Wilmington Trust Company, Wilmington, Delaware, ABA # 03-11-000-92, Account No. 50849-0, Attention: Robert Hines, Reference: Atlas Air 2000-1C, or to such other account as the Paying Agent may direct from time to time in writing to the Depositary and the Escrow Agent and (ii) in the case of any withdrawal of all or a portion of the Deposit pursuant to a Notice of Purchase Withdrawal, directly to or as directed by the Pass Through Trustee as specified and in the manner provided in such Notice of Purchase Withdrawal. The Depositary hereby waives any and all rights of set-off, combination of accounts, right of retention or similar right (whether arising under applicable law, contract or otherwise) it may have against the Deposit howsoever arising. All payments on or in respect of the Deposit shall be made free and clear of and without reduction for or on account of any and all taxes, levies or other impositions or charges (collectively, "Taxes"). However, if the Depositary or the Paying Agent (pursuant to Section 2.04 of the Escrow Agreement) shall be required by law to deduct or withhold any Taxes from or


in respect of any sum payable hereunder, the Depositary shall (i) make such deductions or withholding, (ii) pay the full amount deducted or withheld (including in respect of such additional amounts) to the competent taxation authority and (iii) if the Taxes required to be deducted or withheld are imposed by the Federal Republic of Germany or any political subdivision thereof, pay such additional amounts as may be necessary in order that the actual amount received by the designated recipient of such sum under this Agreement or the Escrow Agreement after such deduction or withholding equals the sum it would have received had no such deduction or withholding been required. If the date on which any payment due on the Deposit would otherwise fall on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day, with the same force and effect as if made on such scheduled date, and no additional interest shall accrue in respect of such extension.

SECTION 5. Representation and Warranties. The Depositary hereby represents and warrants to Atlas, the Escrow Agent, the Pass Through Trustee and the Paying Agent that:

(f) there are no pending or, to its knowledge, threatened actions, suits, investigations or proceedings (whether or not purportedly on behalf of it) against or affecting it or any of its property before or by any court or administrative agency which, if adversely determined, (i) would adversely affect the ability of it to perform its obligations under this Agreement or (ii) would call into question or challenge the validity of this Agreement or the enforceability hereof in accordance with the terms hereof, nor is the Depositary in default with respect to any order of any court, governmental authority, arbitration board or administrative agency so as to adversely affect its ability to perform its obligations under this Agreement; and

(g) the Depositary will make all payments under this Agreement from its own funds and not from funds provided by, or on deposit from, Atlas or any of Atlas' subsidiaries.

The Company shall, or shall cause the Trustees to, commence the Exchange Offer by mailing the related exchange offer Prospectus and accompanying documents to each Holder stating, in addition to such other disclosures as are required by applicable law:

(i) that the Exchange Offer is being made pursuant to this Registration Rights Agreement and that all Registrable Certificates validly tendered will be accepted for exchange;

(iii) that any Registrable Certificate not tendered will remain outstanding and continue to accrue interest, but will not retain any rights under this Registration Rights Agreement;

(iv) that Holders electing to have a Registrable Certificate exchanged pursuant to the Exchange Offer will be required to surrender such Registrable Certificate,


together with the enclosed letters of transmittal, to the institution and at the address (located in the Borough of Manhattan, The City of New York) specified in the notice prior to the close of business on the last Exchange Date; and

As soon as practicable after the last Exchange Date, the Company shall or shall cause the Trustees to:

(i) accept for exchange Registrable Certificates or portions thereof tendered and not validly withdrawn pursuant to the Exchange Offer;

(ii) deliver, or cause to be delivered, to the Class A Trustee for cancellation all Class A Registrable Certificates or portions thereof so accepted for exchange by the Company, and issue, and cause the Class A Trustee to promptly authenticate and mail to each Class A Holder, Class A Exchange Certificates equal in principal amount to the principal amount of the Class A Registrable Certificates surrendered by such Class A Holder;

(iv) deliver, or cause to be delivered, to the Class C Trustee for cancellation all Class C Registrable Certificates or portions thereof so accepted for exchange by the Company, and issue, and cause the Class C Trustee to promptly authenticate and mail to each Class C Holder, Class C Exchange Certificates equal in principal amount to the principal amount of the Class C Registrable Certificates surrendered by such Class C Holder.

The Company shall use its best efforts to complete the Exchange Offer as provided above and shall comply with the applicable requirements of the 1933 Act, the 1934 Act and other applicable laws, rules and regulations in connection with the Exchange Offer. The Exchange Offer shall not be subject to any conditions, other than that the Exchange Offer does not violate applicable law or any applicable interpretation of the Staff of the SEC. The Company shall inform the Placement Agents of the names and addresses of the Holders to whom the Exchange Offer is


made, and the Placement Agents shall have the right, subject to applicable law, to contact such Holders and otherwise facilitate the tender of Registrable Certificates in the Exchange Offer.

(b) In the event that (i) the Company determines that the Exchange Offer Registration provided for in Section 2(a) above is not available or may not be consummated as soon as practicable after the last Exchange Date because it would violate applicable law or the applicable interpretations of the Staff of the SEC, (ii) the Exchange Offer Registration Statement is not declared effective with 60 calendar days after the filing thereof with the SEC, (iii) the Exchange Offer is not for any other reason consummated within 30 days of the effectiveness of an Exchange Offer Registration Statement or (iv) the Exchange Offer has been completed and in the opinion of counsel for the Placement Agents a Registration Statement must be filed and a Prospectus must be delivered by the Placement Agents in connection with any offering or sale of Registrable Certificates, the Company shall use its best efforts to cause to be filed as soon as practicable after such determination, date or notice of such opinion of counsel is given to the Company, as the case may be, a Shelf Registration Statement providing for the sale by the Holders of all of the Registrable Certificates, and to use its best efforts to cause such Shelf Registration Statement to be declared effective by the SEC by the 180th calendar day after the Closing Date. The Company agrees to use its best efforts to keep the Shelf Registration Statement continuously effective for a period of two years after its effective date or such shorter period that will terminate when all of the Registrable Certificates covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement. The Company further agrees to supplement or amend the Shelf Registration Statement, if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement or by the 1933 Act or by any other rules and regulations thereunder for shelf registration or if reasonably requested by a Holder with respect to information relating to such Holder, and to use its best efforts to cause any such amendment to become effective and such Shelf Registration Statement to become usable as soon as thereafter practicable. The Company agrees to furnish to the Holders of Registrable Certificates copies of any such supplement or amendment promptly after its being used or filed with the SEC.

(c) The Company shall pay all Registration Expenses in connection with the registration pursuant to Section 2(a) or Section 2(b). Each Holder shall pay all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder's Registrable Certificates pursuant to the Shelf Registration Statement.

(d) An Exchange Offer Registration Statement pursuant to
Section 2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become effective unless it has been declared effective by the SEC; provided, however, that if, after it has been declared effective, the offering of Registrable Certificates pursuant to a Shelf Registration Statement is interfered with by any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court, such Shelf Registration Statement will be deemed not to have become effective during the period of such interference until the offering of Registrable Certificates pursuant to such Registration Statement may legally resume. In the event that neither the consummation of the Exchange Offer nor the declaration by the SEC of a Shelf Registration to be effective (each a "Registration Event") occurs on or prior to


the 210th day after the Closing Date, the interest rate per annum borne by the Certificates shall be increased by 0.50%, effective from and including such 210th day, to but excluding the date on which a Registration Event occurs. In the event that the Shelf Registration Statement ceases to be effective at any time during the period specified by Section 2(b) hereof for more than 60 days, whether or not consecutive, during any 12-month period, the interest rate borne by the Certificates shall be increased by 0.50% per annum from the 61st day of the applicable 12-month period such Shelf Registration Statement ceases to be effective until such time as the Shelf Registration Statement again becomes effective.

(e) Without limiting the remedies available to the Placement Agents and the Holders, the Company acknowledges that any failure by the Company to comply with its obligations under Section 2(a) and Section 2(b) hereof may result in material irreparable injury to the Placement Agents or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, each Placement Agent or any Holder may obtain such relief as may be required to specifically enforce the Company's obligations under Section 2(a) and Section 2(b) hereof.

make such representations and warranties to the Holders and any Underwriters of such Registrable Certificates with respect to the business of the Company and its subsidiaries, the Registration Statement, Prospectus and documents incorporated by reference or deemed incorporated by reference, if any, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and confirm the same if and when requested, (ii) obtain opinions of counsel to the Company (which counsel and opinions, in form, scope and substance, shall be reasonably satisfactory to the Holders and such Underwriters and their respective counsel) addressed to each selling Holder and Underwriter of Registrable Certificates, covering the matters customarily covered in opinions requested in underwritten offerings, (iii) obtain "cold comfort" letters from the independent certified public accountants of the Company (and, if necessary, any other certified public accountant of any subsidiary of the Company, or of any business acquired by the Company for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to each selling Holder and Underwriter of Registrable Certificates, such letters to be in customary form and covering matters of the type customarily covered in "cold comfort" letters in connection with underwritten offerings, and (iv) deliver such documents and certificates as may be reasonably requested by the Holders of a majority in principal amount of the Registrable Certificates being sold or the Underwriters, and which are customarily delivered in underwritten offerings, to evidence the continued validity of the representations and warranties of the Company made pursuant to clause (i) above and to evidence compliance with any customary conditions contained in an underwriting agreement.

In the case of a Shelf Registration Statement, the Company may require each Holder of Registrable Certificates to furnish to the Company such information regarding the Holder and the proposed distribution by such Holder of such Registrable Certificates as the Company may from time to time reasonably request in writing.

In the case of a Shelf Registration Statement, each Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(e)(v) hereof, such Holder will forthwith discontinue disposition of Registrable Certificates pursuant to a Shelf Registration Statement until such Holder's receipt of the copies of the supplemented or amended Prospectus contemplated by Section 3(i) hereof, and, if so directed by the Company, such Holder will deliver to the Company (at the Company's expense) all copies in its possession, other than permanent file copies then in such Holder's possession, of the Prospectus covering such Registrable Certificates current at the time of receipt of such notice. If the Company shall give any such notice to suspend the disposition of Registrable Certificates pursuant to a Registration Statement, the Company shall extend the period during which the Registration Statement shall be maintained effective pursuant to this Registration Rights Agreement by the number of days during the period from and including the date of the giving of such notice to and including the date when the Holders shall have received copies of the supplemented or amended Prospectus necessary to resume such dispositions.

In any such Underwritten Offering, the investment banker or investment bankers and manager or managers (the "Underwriters") that will administer the offering will be selected by the Majority Holders of the Registrable Certificates included in such offering.

4. Participation of Broker-Dealers in Exchange Offer. (a) The Staff of the SEC has taken the position that any broker-dealer that receives Exchange Certificates for its own account in the Exchange Offer in exchange for Certificates that were acquired by such broker-dealer as a result of market making or other trading activities (a "Participating Broker-Dealer") may be deemed to be an "underwriter" within the meaning of the 1933 Act and must deliver a prospectus meeting the requirements of the 1933 Act in connection with any resale of such Exchange Certificates.

The Company understands that it is the Staff's position that if the Prospectus contained in the Exchange Offer Registration Statement includes a plan of distribution containing a statement to the above effect and the means by which Participating Broker-Dealers may resell the Exchange Certificates, without naming the Participating Broker-Dealers or specifying the amount of Exchange Certificates owned by them, such Prospectus may be delivered by Participating Broker-Dealers to satisfy their prospectus delivery obligation under the 1933 Act in connection with resales of Exchange Certificates for their own accounts, so long as the Prospectus otherwise meets the requirements of the 1933 Act.

(b) In light of Section 4(a) above, notwithstanding the other provisions of this Registration Rights Agreement, the Company agrees that the provisions of this Registration Rights Agreement as they relate to a Shelf Registration shall also apply to an Exchange Offer Registration to the extent, and with such reasonable modifications thereto as may be reasonably requested by the Placement Agents or by one or more Participating Broker-Dealers, in each case as provided in clause (ii) below, in order to expedite or facilitate the disposition of any Exchange Certificates by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above; provided that:

(i) the Company shall not be required to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement, as would otherwise be contemplated by Section 3(i), for a period exceeding 180 days after the last Exchange Date (as such period may be extended pursuant to the penultimate paragraph of Section 3 of this Agreement) and Participating Broker-Dealers shall not be authorized by the Company to deliver and shall not deliver such Prospectus after such period in connection with the resales contemplated by this Section 4; and

(ii) the application of the Shelf Registration procedures set forth in Section 3 of this Registration Rights Agreement to an Exchange Offer Registration, to the extent not required by the positions of the Staff of the SEC or the 1933 Act and the rules and regulations thereunder, will be in conformity with the reasonable request to the Company


by the Placement Agents or with the reasonable request in writing to the Company by one or more broker-dealers who certify to the Placement Agents and the Company in writing that they anticipate that they will be Participating Broker-Dealers; provided that in connection with such application of the Shelf Registration procedures set forth in Section 3 to an Exchange Offer Registration, the Company shall be obligated (x) to deal only with one entity representing the Participating Broker-Dealers, which shall be Morgan Stanley unless it elects not to act as such representative, (y) to pay the fees and expenses of only one counsel representing the Participating Broker-Dealers, which shall be counsel to the Placement Agents unless such counsel elects not to so act, and (z) to cause to be delivered only one, if any, "cold comfort" letter with respect to the Prospectus in the form existing on the last Exchange Date and with respect to each subsequent amendment or supplement, if any, effected during the period specified in clause (i) above.

(c) The Placement Agents shall have no liability to the Company or any Holder with respect to any request that it may make pursuant to
Section 4(b) above.

5. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Placement Agent, each Holder and each person, if any, who controls any Placement Agent or any Holder within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, or is under common control with, or is controlled by, any Placement Agent or any Holder, from and against all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred by any Placement Agent, any Holder or any such controlling or affiliated person in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto) pursuant to which Exchange Certificates or Registrable Certificates were registered under the 1933 Act, including all documents incorporated therein by reference, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or caused by any untrue statement or alleged untrue statement of a material fact contained in any Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Placement Agents or any Holder (and, in the case of such losses, claims, damages or liabilities incurred by Morgan Stanley, by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to Morgan Stanley Capital Services, Inc. or to Morgan Stanley Dean Witter & Co.) furnished to the Company in writing by the Placement Agents or any selling Holder expressly for use therein, provided, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Placement Agent from whom the person asserting any such losses, claims, damages or liabilities purchased Offered Certificates, or any person controlling such Placement Agent, if a copy of the final prospectus (as then amended or supplemented if the Company shall have furnished any amendments thereto) was not sent or given by or on behalf of such Placement Agent to such


person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Offered Certificates (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or liabilities, unless such failure is the result of noncompliance by the Company with Section 3 hereof. In connection with any Underwritten Offering permitted by Section 3, the Company will also indemnify the Underwriters, if any, selling brokers, dealers and similar securities industry professionals participating in the distribution, their officers and directors and each Person who controls such Persons (within the meaning of the 1933 Act and the 1934 Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any Registration Statement.

(b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, each Placement Agent, the other selling Holders and each of their respective directors, officers who sign the Registration Statement and each Person, if any, who controls the Company, any Placement Agent or any other selling Holder within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the foregoing indemnity from the Company to the Placement Agents and the Holders, but only with reference to information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement (or any amendment thereto) or any Prospectus (or any amendment or supplement thereto).

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either of paragraph (a) or paragraph (b) above, such person (the "indemnified party") shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (a) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Placement Agents and all persons, if any, who control any Placement Agent within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, (b) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (c) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Holders and all persons, if any, who control any Holders within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In such case involving the Placement Agents and persons who control any Placement Agent, such firm shall be designated


in writing by the Placement Agents. In such case involving the Holders and such persons who control Holders, such firm shall be designated in writing by the Majority Holders. In all other cases, such firm shall be designated by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but, if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party for such fees and expenses of counsel in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which such indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) If the indemnification provided for in paragraph (a) or paragraph (b) of this Section 4 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Holders shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Holders and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Holders' respective obligations to contribute pursuant to this Section 5(d) are several in proportion to the respective number of Registrable Certificates of such Holder that were registered pursuant to a Registration Statement.

(e) The Company and each Holder agree that it would not be just or equitable if contribution pursuant to this Section 5 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5, no Holder shall be required to


indemnify or contribute any amount in excess of the amount by which the total price at which Registrable Certificates were sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

The indemnity and contribution provisions contained in this
Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Placement Agents, any Holder or any person controlling any Placement Agent or any Holder, or by or on behalf of the Company, its officers or directors or any person controlling the Company, (iii) acceptance of any of the Exchange Certificates and (iv) any sale of Registrable Certificates pursuant to a Shelf Registration Statement.

6. Miscellaneous. (a) No Inconsistent Agreements. The Company has not entered into, and on or after the date of this Registration Rights Agreement will not enter into, any agreement which is inconsistent with the rights granted to the Holders of Registrable Certificates in this Registration Rights Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company's other issued and outstanding securities under any such agreements.

(b) Amendments and Waivers. The provisions of this Registration Rights Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Company has obtained the written consent of Holders of at least a majority in aggregate principal amount of the outstanding Registrable Certificates affected by such amendment, modification, supplement, waiver or consent; provided, however, that no amendment, modification, supplement, waiver or consents to any departure from the provisions of Section 5 hereof shall be effective as against any Holder of Registrable Certificates unless consented to in writing by such Holder.

(c) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, telex, telecopier, or any courier guaranteeing overnight delivery (i) if to a Holder, at the most current address given by such Holder to the Company by means of a notice given in accordance with the provisions of this
Section 6(c), which address initially is, with respect to the Placement Agents, the address set forth in the Placement Agreement, and (ii) if to the Company, initially at the Company's address set forth in the Placement Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c).


All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five business days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt is acknowledged, if telecopied; and on the next business day if timely delivered to an air courier guaranteeing overnight delivery.

Copies of all such notices, demands, or other communications shall be concurrently delivered by the person giving the same to each Trustee, at the address specified in the Applicable Trust Agreement.

(d) Successors and Assigns. This Registration Rights Agreement shall inure to the benefit of and be binding upon the successors, assigns and transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent Holders; provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Certificates in violation of the terms of the Placement Agreement or the Trust Agreements. If any transferee of any Holder shall acquire Registrable Certificates, in any manner, whether by operation of law or otherwise, such Registrable Certificates shall be held subject to all of the terms of this Registration Rights Agreement, and by taking and holding such Registrable Certificates, such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Registration Rights Agreement and such Person shall be entitled to receive the benefits hereof. The Placement Agents (in their capacity as Placement Agents) shall have no liability or obligation to the Company with respect to any failure by any other Holder to comply with, or any breach by any other Holder of, any of the obligations of such other Holder under this Registration Rights Agreement.

(e) Purchases and Sales of Certificates. The Company shall not, and shall use its best efforts to cause its affiliates (as defined in Rule 405 under the 1933 Act), not to purchase and then resell or otherwise transfer any Certificates.

(f) Third Party Beneficiary. The Holders shall be third party beneficiaries to the agreements made hereunder and shall have the right to enforce such agreements directly to the extent they deem such enforcement necessary or advisable to protect their rights hereunder.

(g) Counterparts. This Registration Rights Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

(h) Headings. The headings in this Registration Rights Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

(i) Governing Law. This Registration Rights Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

(j) Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable,


the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein shall not be affected or impaired thereby.

(k) Trustees. The Trustees shall take such action as may be reasonably requested by the Company in connection with the Company satisfying its obligations arising under this Agreement.

In addition, each Trustee hereby agrees to cause the Equipment Notes purchased by the related Trust to be registered in the name

21

of the Subordination Agent or its nominee, as agent and trustee for such Trustee, to be held in trust by the Subordination Agent solely for the purpose of facilitating the enforcement of the subordination and other provisions of this Agreement.

(b) Except as otherwise expressly provided in the next succeeding sentence of this Section 2.1, all payments to be made by the Subordination Agent hereunder shall be made only from amounts received by it that constitute Scheduled Payments, Special Payments, or payments under Section 9.1 of the Leased Aircraft Participation Agreements, Section 8.1 of the Owned Aircraft Participation Agreements or payments under Section 6 of the Note Purchase Agreement, and only to the extent that the Subordination Agent shall have received sufficient income or proceeds therefrom to enable it to make such payments in accordance with the terms hereof. Each of the Trustees and the Subordination Agent hereby agrees and, as provided in each Trust Agreement, each Certificateholder, by its acceptance of a Certificate, and each Liquidity Provider, by entering into the Liquidity Facility to which it is a party, has agreed to look solely to such amounts to the extent available for distribution to it as provided in this Agreement and to the relevant Deposits and that none of the Trustees, Owner Trustees, Loan Trustees, Owner Participants nor the Subordination Agent is personally liable to any of them for any amounts payable or any liability under this Agreement, any Trust Agreement, any Liquidity Facility or such Certificate, except (in the case of the Subordination Agent) as expressly provided herein or (in the case of the Trustees) as expressly provided in each Trust Agreement or (in the case of the Owner Trustees and the Loan Trustees) as expressly provided in any Operative Agreement.

SECTION 2.2. Trust Accounts. (a) Upon the execution of this Agreement, the Subordination Agent shall establish and maintain in its name (i) the Collection Account as an Eligible Deposit Account, bearing a designation clearly indicating that the funds deposited therein are held in trust for the benefit of the Trustees, the Certificateholders and the Liquidity Providers, and

Upon such establishment and maintenance under Section 3.6(f) hereof, the Cash Collateral Accounts shall, together with the Collection Account, constitute the "Trust Accounts" hereunder.

(b) Funds on deposit in the Trust Accounts shall be invested and reinvested by the Subordination Agent in Eligible Investments selected by the Subordination Agent if such investments are reasonably available and have maturities no later than the earlier of (i) 90 days following the date of such investment and (ii) the Business Day immediately preceding the Regular Distribution Date or the date of the related distribution pursuant to Section 2.4 hereof, as the case may be, next following the date of such investment; (or, in the case of any amount on deposit in the Cash Collateral Account with respect to any Liquidity Facility, the Business Day immediately preceding the scheduled Interest Payment Date with respect to such Liquidity Facility next following the date of such investment); provided, however, that following the making of a Downgrade Drawing or a Non-Extension Drawing under any Liquidity Facility, the Subordination Agent shall invest and reinvest amounts on deposit in the related Cash Collateral

34

SECTION 3.5. Payments to the Trustees and the Liquidity Providers.

SECTION 3.6. Liquidity Facilities. (a) Interest Drawings. If on any Distribution Date, after giving effect to the subordination provisions of this Agreement, the Subordination Agent shall not have sufficient funds for the payment of any amounts due and owing in respect of accrued interest on the Class A Certificates, the Class B Certificates or the Class C Certificates (at the Stated Interest Rate for such Class of Certificates), then, prior to 1:00 PM (New York City time) on such Distribution Date, the Subordination Agent shall request a drawing (each such drawing, an "Interest Drawing") under each Liquidity Facility with respect to such Class of Certificates in an amount equal to the lesser of (i) of an amount sufficient to pay the amount of such accrued interest (at the Stated Interest Rate for such Class of Certificates) and (ii) the Available Amount under such Liquidity Facility, and shall pay such amount to the Trustee with respect to such Class of Certificates in payment of such accrued interest.

(b) Application of Interest Drawings. Notwithstanding anything to the contrary contained in this Agreement, (i) all payments received by the Subordination Agent in respect of an Interest Drawing under the Class A Liquidity Facility and all amounts withdrawn by the Subordination Agent from the Class A Cash Collateral Account, and payable in each case to the Class A Certificateholders or the Class A Trustee, shall be promptly distributed to the Class A Trustee, (ii) all payments received by the Subordination Agent in respect of an Interest Drawing under the Class B Liquidity Facility and all amounts withdrawn by the Subordination Agent from the Class B Cash Collateral Account, and payable in each case to the Class B Certificateholders, shall be promptly distributed to the Class B Trustee and (iii) all payments received by the Subordination Agent in respect of an Interest Drawing under the Class C Liquidity Facility and all amounts withdrawn by the Subordination Agent from the Class C Cash Collateral Account, and payable in each case to the Class C Certificateholders, shall be promptly distributed to the Class C Trustee.

(c) Downgrade Drawings. If at any time (i) in the case of any Liquidity Facility (other than as provided in clause (ii) below) the short-term unsecured debt rating of the Liquidity Provider thereof issued by any Rating Agency is lower than the applicable Threshold Rating or (ii) (with respect to any MSCS Liquidity Facility, so long as MSCS is the Liquidity Provider thereunder) the short-term unsecured debt rating of the Guarantor issued by any Rating Agency is lower than the applicable Threshold Rating or the related Guarantee Agreement ceases to be in full force and effect, becomes invalid or unenforceable or the Guarantor denies its liability thereunder (any such occurrence, a "Guarantee Event"), within 10 days after receiving notice of such downgrading or Guarantee Event, as the case may be (but not later than the expiration date of the Liquidity Facility issued by the relevant Liquidity Provider (the "Downgraded Facility")), such Liquidity Provider or Atlas may arrange for a Replacement

35

Liquidity Provider to issue and deliver a Replacement Liquidity Facility to the Subordination Agent. If a Downgraded Facility has not been replaced in accordance with the terms of this paragraph, the Subordination Agent shall, on such 10th (or if such day is not a Business Day, on the next succeeding Business Day) (or, if earlier, the expiration date of such Downgraded Facility), request a drawing in accordance with and to the extent permitted by such Downgraded Facility (such drawing, a "Downgrade Drawing") of all available and undrawn amounts thereunder. Amounts drawn pursuant to a Downgrade Drawing shall be maintained and invested as provided in Section 3.6(f) hereof. The Liquidity Provider may also arrange for a Replacement Liquidity Provider to issue and deliver a Replacement Liquidity Facility at any time after such Downgrade Drawing so long as such Downgrade Drawing has not been reimbursed in full to the Liquidity Provider.

(d) Non-Extension Drawings. If the any Liquidity Facility with respect to any Class of Certificates is scheduled to expire on a date (the "Stated Expiration Date") prior to the date that is 15 days after the Final Legal Distribution Date for such Class of Certificates, then, no earlier than the 60th day and no later than the 40th day prior to the then Stated Expiration Date, the Subordination Agent shall request that such Liquidity Provider extend the Stated Expiration Date for a period of 364 days after the Stated Expiration Date (unless the obligations of such Liquidity Provider thereunder are earlier terminated in accordance therewith). The applicable Liquidity Provider shall advise the Borrower, no earlier than 40 days and no later than 25 days prior to such Stated Expiration Date, whether, in its sole discretion, it agrees to so extend the Stated Expiration Date for such Liquidity Facility. If, on or before such 25th day, such Liquidity Facility shall not have been so extended or replaced in accordance with Section 3.6(e), or if such Liquidity Provider fails irrevocably and unconditionally to advise the Borrower on or before the 25th day prior to the Stated Expiration Date then in effect that such Stated Expiration Date shall be so extended, the Subordination Agent shall, on such 25th day (or as soon as possible thereafter), in accordance with and to the extent permitted by the terms of the expiring Liquidity Facility (a "Non-Extended Facility"), request a drawing under such expiring Liquidity Facility (such drawing, a "Non-Extension Drawing") of all available and undrawn amounts thereunder. Amounts drawn pursuant to a Non-Extension Drawing shall be maintained and invested in accordance with Section 3.6(f) hereof. Notwithstanding the immediately preceding three sentences, so long as MSCS is the Liquidity Provider for any MSCS Liquidity Facility, the Stated Expiration Date therefor shall be automatically extended, effective on the 25th day prior to such Stated Expiration Date (unless such Stated Expiration Date is on or after the date that is 15 days after the Final Legal Distribution Date for the relevant Class of Certificates), for a period of 364 days after such Stated Expiration Date (unless the obligations of such Liquidity Provider are earlier terminated in accordance with such Liquidity Facility) without the necessity of any act by the Subordination Agent or such Liquidity Provider, unless such Liquidity Provider shall advise the Subordination Agent, prior to such 25th day, that it does not agree to such extension of the Stated Expiration Date, in which event, the Subordination Agent shall, on such 25th day (or as soon as possible thereafter), in accordance with and to the extent permitted by the terms of the Non-Extended Facility, request a Non-Extension Drawing under the Non-Extended Facility of all available and undrawn amounts thereunder.

36

(e) Issuance of Replacement Liquidity Facility. (i) At any time, Atlas may, at its option, with cause or without cause, arrange for a Replacement Liquidity Facility to replace any Liquidity Facility for any Class of Certificates (including any Replacement Liquidity Facility provided pursuant to Section 3.6(e)(ii) hereof); provided, however, that neither WESTLB nor MSCS shall be replaced by Atlas as a Liquidity Provider with respect to any Class of Certificates prior to the fourth anniversary of the Closing Date unless (A) there shall have become due to such Liquidity Provider, or such Liquidity Provider shall have demanded, amounts pursuant to Section 3.01, 3.02 or 3.03 of any Liquidity Facility or pursuant to the Tax Letter and the replacement of such Liquidity Provider would reduce or eliminate the obligation to pay such amounts or Atlas determines in good faith that there is a substantial likelihood that such Liquidity Provider will have the right to claim any such amounts (unless such Liquidity Provider waives, in writing, any right it may have to claim such amounts), which determination shall be set forth in a certificate delivered by Atlas to such Liquidity Provider setting forth the basis for such determination and accompanied by an opinion of outside counsel selected by Atlas and reasonably acceptable to such Liquidity Provider verifying the legal conclusions, if any, of such certificate relating to such basis, provided that, in the case of any likely claim for such amounts based upon any proposed, or proposed change in, law, rule, regulation, interpretation, directive, requirement, request or administrative practice, such opinion may assume the adoption or promulgation of such proposed matter, (B) it shall become unlawful or impossible for such Liquidity Provider (or its Lending Office) to maintain or fund its LIBOR Advances as described in Section 3.10 of any Liquidity Facility,
(C) with respect to any Liquidity Facility for which MSCS is not the Liquidity Provider, the short-term unsecured debt rating of such Liquidity Provider or, with respect to the MSCS Liquidity Facilities (so long as MCSC is the Liquidity Provider thereunder), the short-term unsecured debt rating of the Guarantor, is downgraded by any Rating Agency and there is a resulting downgrade in the rating by any Rating Agency of any related Class of Certificates, (D) a Downgrade Drawing or a Non-Extension Drawing shall have occurred under any Liquidity Facility, or (E) such Liquidity Provider shall have breached any of its payment (including, without limitation, funding) obligations under any Liquidity Facility. If such Replacement Liquidity Facility is provided at any time after a Downgrade Drawing or Non-Extension Drawing has been made, all funds on deposit in the relevant Cash Collateral Account will be returned to the Liquidity Provider being replaced.

(ii) If any Liquidity Provider shall determine not to extend any of its Liquidity Facility in accordance with Section 3.6(d), then such Liquidity Provider may, at its option, arrange for a Replacement Liquidity Facility to replace such Liquidity Facility during the period no earlier than 40 days and no later than 25 days prior to the then effective Stated Expiration Date of such Liquidity Facility.

(iii) No Replacement Liquidity Facility arranged by Atlas or a Liquidity Provider in accordance with clause (i) or (ii) above, respectively, shall become effective and no such Replacement Liquidity Facility shall be deemed a Liquidity Facility" under the Operative Agreements (in each case other than insofar as necessary to permit the repayment of amounts owed to the replaced Liquidity Provider), unless and until (A) each of the conditions referred to in clause (iv) below shall have been satisfied, (B) if such Replacement Liquidity Facility shall materially adversely affect the rights, remedies,

37

interests or obligations of the Class A Certificateholders, the Class B Certificateholders or the Class C Certificateholders under any of the Operative Agreements, the applicable Trustee shall have consented, in writing, to the execution and issuance of such Replacement Liquidity Facility and (C) in the case of a Replacement Liquidity Facility arranged by a Liquidity Provider under Section 3.6(e)(ii), such Replacement Liquidity Facility is acceptable to Atlas.

(iv) In connection with the issuance of each Replacement Liquidity Facility, the Subordination Agent shall (x) prior to the issuance of such Replacement Liquidity Facility, obtain written confirmation from each Rating Agency that such Replacement Liquidity Facility will not cause a reduction of any rating then in effect for any Class of Certificates by such Rating Agency (without regard to any downgrading of any rating of any Liquidity Provider being replaced pursuant to Section 3.6(c) hereof), (y) pay all Liquidity Obligations then owing to the replaced Liquidity Provider (which payment shall be made first from available funds in the Cash Collateral Account as described in clause (vii) of Section 3.6(f) hereof, and thereafter from any other available source, including, without limitation, a drawing under the Replacement Liquidity Facility) and (z) cause the issuer of the Replacement Liquidity Facility to deliver the Replacement Liquidity Facility to the Subordination Agent, together with a legal opinion opining that such Replacement Liquidity Facility is an enforceable obligation of such Replacement Liquidity Provider.

(v) Upon satisfaction of the conditions set forth in clauses
(iii) and (iv) of this Section 3.6(e), (w) the replaced Liquidity Facility shall terminate, (x) the Subordination Agent shall, if and to the extent so requested by Atlas or the Liquidity Provider being replaced, execute and deliver any certificate or other instrument required in order to terminate the replaced Liquidity Facility, shall surrender the replaced Liquidity Facility to the Liquidity Provider being replaced and shall execute and deliver the Replacement Liquidity Facility and any associated Fee Letter, (y) each of the parties hereto shall enter into any amendments to this Agreement necessary to give effect to (1) the replacement of the applicable Liquidity Provider with the applicable Replacement Liquidity Provider and (2) the replacement of the applicable Liquidity Facility with the applicable Replacement Liquidity Facility and (z) the applicable Replacement Liquidity Provider shall be deemed to be a Liquidity Provider with the rights and obligations of a Liquidity Provider hereunder and under the other Operative Agreements and such Replacement Liquidity Facility shall be deemed to be a Liquidity Facility hereunder and under the other Operative Agreements.

(f) Cash Collateral Accounts; Withdrawals; Investments. In the event the Subordination Agent shall draw all available amounts under the Class A Liquidity Facility, the Class B Liquidity Facility or the Class C Liquidity Facility pursuant to Section 3.6(c), 3.6(d) or 3.6(i) hereof, or in the event amounts are to be deposited in the Cash Collateral Account pursuant to subclause (B) of clause "third" of Section 2.4(b), subclause (B) of clause "third" of
Section 3.2 or subclause (B) of clause "fourth" of Section 3.3, amounts so drawn or to be deposited, as the case may be, shall be deposited by the Subordination Agent in the Class A Cash Collateral Account, the Class B Cash Collateral Account or the Class C Cash Collateral Account,

38

respectively. All amounts on deposit in each Cash Collateral Account shall be invested and reinvested in Eligible Investments in accordance with Section 2.2(b) hereof. Investment Earnings on amounts on deposit in each Cash Collateral Account shall be deposited in the Collection Account on each Interest Payment Date under the related Liquidity Facility and applied on such Interest Payment Date in accordance with Section 2.4, 3.2, 3.3 or 3.4 (as applicable). The Subordination Agent shall deliver a written statement to Atlas and each Liquidity Provider one day prior to each Interest Payment Date setting forth the aggregate amount of Investment Earnings held in the applicable Cash Collateral Accounts as of such date.

all amounts on deposit in the Cash Collateral Account in respect of such Class of Certificates and shall deposit such amount in the Collection Account.

With respect to any Interest Drawing under the Liquidity Facility for any Trust, upon the reimbursement of the applicable Liquidity Provider for all or any part of the amount of such Interest Drawing, together with any accrued interest thereon, the Available Amount of such Liquidity Facility shall be reinstated by an amount equal to the amount of such Interest Drawing so reimbursed to the applicable Liquidity Provider but not to exceed the Maximum Commitment with respect to such Liquidity Facility; provided, however, that such Liquidity Facility shall not be so reinstated in part or in full at any time if (x) both a Performing Note Deficiency exists and a Liquidity Event of Default shall have occurred and be continuing with respect to the relevant Liquidity Facility or (y) a Final Drawing shall have occurred with respect to such Liquidity Facility. In the event that, with respect to any particular Liquidity Facility (i) funds are withdrawn from any Cash Collateral Account pursuant to clause (i), (ii) or (iii) of Section 3.6(f) hereof or (ii) such Liquidity Facility shall become a Downgraded Facility or a Non-Extended Facility at a time when unreimbursed Interest Drawings under such Liquidity Facility have reduced the Available Amount thereunder to zero, then funds received by the Subordination Agent at any time other than (x) any time when a Liquidity Event of Default shall have occurred and be continuing with respect to such Liquidity Facility and a Performing Note Deficiency exists or (y) any time after a Final Drawing shall have occurred with respect to such Liquidity Facility shall be deposited in such Cash Collateral Account as and to the extent provided in clause "third" of Section 2.4(b), clause "third" of Section 3.2 or clause "fourth" of Section 3.3, as applicable, and applied in accordance with
Section 3.6(f) hereof.

Amounts drawn pursuant to a Final Drawing shall be maintained and invested in accordance with Section 3.6(f) hereof.

(j) Reduction of Stated Amount. Promptly following each date on which the Required Amount of the Liquidity Facility for a Class of Certificates is reduced as a result of a reduction in the Pool Balance with respect to such Certificates, the Subordination Agent shall, if any such Liquidity Facility provides for reductions of the Stated Amount of such Liquidity Facility and regardless of whether such reductions are automatic, request such Liquidity Provider for such Class of Certificates to reduce such Stated Amount to an amount equal to the Required Amount with respect to such Liquidity Facility (as calculated by the Subordination Agent after giving effect to such payment). Each such request shall be made in accordance with the provisions of the applicable Liquidity Facility.

41

(k) Relation to Subordination Provisions. Interest Drawings under the Liquidity Facilities and withdrawals from the Cash Collateral Accounts, in each case, in respect of interest on the Certificates of any Class, will be distributed to the Trustee for such Class of Certificates, notwithstanding Sections 3.2, 3.3 and 3.6(h) hereof.

ARTICLE IV

EXERCISE OF REMEDIES

SECTION 4.1. Directions from the Controlling Party. (a) (i) Following the occurrence and during the continuation of an Indenture Event of Default under any Indenture, the Controlling Party shall direct the Subordination Agent, which in turn shall direct the Loan Trustee under such Indenture, in the exercise of remedies available to the holders of the Equipment Notes issued pursuant to such Indenture, including, without limitation, the ability to vote all such Equipment Notes in favor of Accelerating such Equipment Notes in accordance with the provisions of such Indenture. Subject to the Owner Trustees' and the Owner Participants' rights, if any, set forth in the Indentures with respect to Leased Aircraft to purchase the Equipment Notes and the provisions of the next paragraph, if the Equipment Notes issued pursuant to any Indenture have been Accelerated following an Indenture Event of Default with respect thereto, the Controlling Party direct the Subordination Agent to, assign, contract to sell or otherwise dispose of and deliver all (but not less than all) of such Equipment Notes to any Person at public or private sale, at any location at the option of the Controlling Party, all upon such terms and conditions as it may reasonably deem advisable in accordance with applicable law.

(ii) Subject to the Owner Trustees' and the Owner Participants' rights, if any, set forth in the Indentures with respect to Leased Aircraft to purchase the Equipment Notes, and notwithstanding the foregoing, so long as any Certificates remain Outstanding, during the period ending on the date which is nine months after the earlier of
(x) the Acceleration of the Equipment Notes issued pursuant to any Indenture or (y) the occurrence of a Atlas Bankruptcy Event, without the consent of each Trustee, (A) no Aircraft subject to the Lien of such Indenture or such Equipment Notes may be sold if the net proceeds from such sale would be less than the Minimum Sale Price for such Aircraft or such Equipment Notes, and (B) with respect to any Leased Aircraft, the amount and payment dates of rentals payable by Atlas under the Lease for such Aircraft may not be adjusted, if, as a result of such adjustment, the discounted present value of all such rentals would be less than 75% of the discounted present value of the rentals payable by Atlas under such Lease before giving effect to such adjustment, in each case, using the weighted average interest rate of the Equipment Notes issued pursuant to such Indenture as the discount rate.

(iii) At the request of the Controlling Party, the Subordination Agent may from time to time during the continuance of an Indenture Event of Default (and before the occurrence of a Triggering Event) commission LTV Appraisals with respect to the Aircraft subject to such Indenture.

42

(iv) After a Triggering Event occurs and any Equipment Note becomes a Non-Performing Equipment Note, the Subordination Agent shall obtain Appraisals with respect to all of the Aircraft (the "LTV Appraisals") as soon as practicable and additional LTV Appraisals on or prior to each anniversary of the date of such initial LTV Appraisals; provided that if the Controlling Party reasonably objects to the appraised value of the Aircraft shown in such LTV Appraisals, the Controlling Party shall have the right to obtain or cause to be obtained substitute any LTV Appraisals (including any LTV Appraisals based upon physical inspection of the Aircraft).

(b) The Controlling Party shall take such actions as it may reasonably deem most effectual to complete the sale or other disposition of such Aircraft or Equipment Notes. In addition, in lieu of any sale, assignment, contract to sell or other disposition, the Controlling Party may maintain possession of such Equipment Notes and continue to apply monies received in respect of such Equipment Notes in accordance with Article III hereof. In addition, in lieu of such sale, assignment, contract to sell or other disposition, or in lieu of such maintenance of possession, the Controlling Party may, subject to the terms and conditions of the related Indenture, instruct the Loan Trustee under such Indenture to foreclose on the Lien on the related Aircraft.

SECTION 4.2. Remedies Cumulative. Each and every right, power and remedy given to the Trustees, the Liquidity Providers, the Controlling Party or the Subordination Agent specifically or otherwise in this Agreement shall be cumulative and shall be in addition to every other right, power and remedy herein specifically given or now or hereafter existing at law, in equity or by statute, and each and every right, power and remedy whether specifically herein given or otherwise existing may, subject always to the terms and conditions hereof, be exercised from time to time and as often and in such order as may be deemed expedient by any Trustee, any Liquidity Provider, the Controlling Party or the Subordination Agent, as appropriate, and the exercise or the beginning of the exercise of any power or remedy shall not be construed to be a waiver of the right to exercise at the same time or thereafter any other right, power or remedy. No delay or omission by any Trustee, any Liquidity Provider, the Controlling Party or the Subordination Agent in the exercise of any right, remedy or power or in the pursuit of any remedy shall impair any such right, power or remedy or be construed to be a waiver of any default or to be an acquiescence therein.

SECTION 4.3. Discontinuance of Proceedings. In case any party to this Agreement (including the Controlling Party in such capacity) shall have instituted any Proceeding to enforce any right, power or remedy under this Agreement by foreclosure, entry or otherwise, and such Proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Person instituting such Proceeding, then and in every such case each such party shall, subject to any determination in such Proceeding, be restored to its former position and rights hereunder, and all rights, remedies and powers of such party shall continue as if no such Proceeding had been instituted.

43

SECTION 4.4. Right of Certificateholders to Receive Payments Not to Be Impaired. Anything in this Agreement to the contrary notwithstanding but subject to each Trust Agreement, the right of any Certificateholder or any Liquidity Provider, respectively, to receive payments hereunder (including without limitation pursuant to Section 2.4, 3.2 or 3.3 hereof) when due, or to institute suit for the enforcement of any such payment on or after the applicable Distribution Date, shall not be impaired or affected without the consent of such Certificateholder or such Liquidity Provider, respectively.

SECTION 4.5. Undertaking for Costs. In any Proceeding for the enforcement of any right or remedy under this Agreement or in any Proceeding against any Controlling Party or the Subordination Agent for any action taken or omitted by it as Controlling Party or Subordination Agent, as the case may be, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. The provisions of this Section do not apply to a suit instituted by the Subordination Agent, a Liquidity Provider or a Trustee or a suit by Certificateholders holding more than 10% of the original principal amount of any Class of Certificates.

The Subordination Agent shall not be required to take any action under Section 5.1 (other than the first sentence thereof) or Article IV hereof, nor shall any other provision of this Agreement be deemed to impose a duty on the Subordination Agent to take any action, if the Subordination Agent shall have been advised by counsel that such action is contrary to the terms hereof or is otherwise contrary to law.

All covenants and agreements contained herein shall be binding upon, and inure to the benefit of, each of the parties hereto and the successors and assigns of each, all as herein provided.

SECTION 10.7. Headings. The headings of the various Articles and Sections herein and in the table of contents hereto are for convenience of reference only and shall not define or limit any of the terms or provisions hereof.

SECTION 10.8. Counterpart Form. This Agreement may be executed by the parties hereto in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts shall together constitute but one and the same agreement.

SECTION 10.9. Subordination. (a) As (i) between the Liquidity Providers, on the one hand, and the Trustees and the Certificateholders, on the other hand, and (ii) among the Trustee and Certificateholders of each Class this Agreement shall be a subordination agreement for purposes of Section 510 of the United States Bankruptcy Code, as amended from time to time.

(b) Notwithstanding the provisions of this Agreement, if prior to the payment in full to the Liquidity Providers of all Liquidity Obligations then due and payable, any party hereto shall have received any payment or distribution in respect of Equipment Notes or any other amount under the Indentures or other Operative Agreements which, had the subordination provisions of this Agreement been properly applied to such payment, distribution or other amount, would not have been distributed to such Person, then such payment, distribution or other amount shall be received and held in trust by such Person and paid over or delivered to the Subordination Agent for application as provided herein.

(c) If any Trustee, any Liquidity Provider or the Subordination Agent receives any payment in respect of any obligations owing hereunder (or, in the case of the Liquidity Providers, in respect of the Liquidity Obligations), which is subsequently invalidated, declared preferential, set aside and/or required to be repaid to a trustee, receiver or other party, then, to the extent of such payment, such obligations (or, in the case of the Liquidity Providers, such Liquidity Obligations) intended to be satisfied shall be revived and continue in full force and effect as if such payment had not been received.

(d) The Trustees (on behalf of themselves and the holders of Certificates), the Liquidity Providers and the Subordination Agent confirm that the payment priorities specified in Sections 2.4, 3.2 and 3.3 shall apply in all circumstances, notwithstanding the fact that the obligations owed to the Trustees and the holders of Certificates are secured by certain assets and the Liquidity Obligations may not be so secured. The Trustees expressly agree (on behalf of themselves and the holders of Certificates) not to assert priority over the holders of Liquidity

54

Obligations due to their status as secured creditors in any bankruptcy, insolvency or other legal proceeding.

(e) Each of the Trustees (on behalf of themselves and the holders of Certificates), the Liquidity Providers and the Subordination Agent may take any of the following actions without impairing its rights under this Agreement:

(i) obtain a Lien on any property to secure any amounts owing to it hereunder, including, in the case of the Liquidity Providers, the Liquidity Obligations,

(ii) obtain the primary or secondary obligation of any other obligor with respect to any amounts owing to it hereunder, including, in the case of the Liquidity Providers, any of the Liquidity Obligations,

(iii) renew, extend, increase, alter or exchange any amounts owing to it hereunder, including, in the case of the Liquidity Providers, any of the Liquidity Obligations, or release or compromise any obligation of any obligor with respect thereto,

(iv) refrain from exercising any right or remedy, or delay in exercising such right or remedy, which it may have, or

(v) take any other action which might discharge a subordinated party or a surety under applicable law;

provided, however, that the taking of any such actions by any of the Trustees, the Liquidity Providers or the Subordination Agent shall not prejudice the rights or adversely affect the obligations of any other party under this Agreement.

SECTION 10.10. Governing Law. THIS AGREEMENT SHALL IN ALL RESPECTS BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.

SECTION 10.11. Submission to Jurisdiction; Waiver of Jury Trial; Waiver of Immunity. (a) Each of the parties hereto hereby irrevocably and unconditionally:

(i) submits for itself and its property in any legal action or proceeding relating to this Agreement or any other Operative Agreement, or for recognition and enforcement of any judgment in respect hereof or thereof, to the nonexclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and the appellate courts from any thereof;

(ii) consents that any such action or proceeding may be brought in such courts, and waives any objection that it may now or hereafter have to the venue of any such

55

action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(iii) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form and mail), postage prepaid, to each party hereto at its address set forth in Section 10.3 hereof, or at such other address of which the other parties shall have been notified pursuant thereto; and

(iv) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction.

(b) EACH OF THE PARTIES HERETO HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING ESTABLISHED, including, without limitation, contract claims, tort claims, breach of duty claims and all other common law and statutory claims. Each of the parties warrants and represents that it has reviewed this waiver with its legal counsel, and that it knowingly and voluntarily waives its jury trial rights following consultation with such legal counsel. THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

(c) Each Liquidity Provider hereby waives any immunity it may have from the jurisdiction of the courts of the United States of America or of any State and waives any immunity any of its properties located in the United States of America may have from attachment or execution upon a judgment entered by any such court under the United States Foreign Sovereign Immunities Act of 1976 or any similar successor legislation.

W I T N E S S E T H:

WHEREAS, capitalized terms used but not defined herein shall have the meanings ascribed to such terms in Annex A hereto;

WHEREAS, the Company has obtained commitments from the Manufacturer pursuant to the Purchase Agreement for the delivery of the two aircraft listed in Schedule I hereto (together with any aircraft substituted therefor in accordance with the Purchase Agreement and this Agreement prior to the delivery thereof, the "Aircraft");

WHEREAS, pursuant to the Pass Through Trust Agreements set forth in Schedule II hereto, and concurrently with the execution and delivery of this Agreement, separate grantor trusts (collectively, the "Pass Through Trusts" and, individually, a "Pass Through Trust") have been created to facilitate certain of the transactions contemplated hereby, including, without limitation, the issuance and sale of pass through certificates pursuant thereto (collectively, the "Certificates") to provide for all or a portion of the financing of the Aircraft;

WHEREAS, the Company has entered into the Placement Agreement dated January 20, 2000 (the "Placement Agreement") with the several placement agents (the "Placement Agents") named therein, which provides that the Company will cause each Pass Through Trustee to issue and sell the Certificates to the Placement Agents;

WHEREAS, concurrently with the execution and delivery of this Agreement, (i) the Escrow Agents and the Depositary entered into the Deposit Agreements set forth in Schedule III hereto (the "Deposit Agreements") whereby the applicable Escrow Agent agreed to direct the Placement Agents to make the deposit referred to therein on the Issuance Date (each a "Deposit") and to permit the applicable Pass Through Trustee to re-deposit amounts from time to time thereafter, (ii) the Company and the Depositary entered into the Indemnity Agreement, dated as


of the date hereof (the "Indemnity Agreement") and (iii) the Pass Through Trustees, the Placement Agents, the Paying Agents and the Escrow Agents entered into the Escrow and Paying Agent Agreements set forth in Schedule IV hereto (the "Escrow Agreements") whereby, among other things, (a) the Placement Agents agreed to deliver an amount equal to the amount of the Deposits to the Depositary on behalf of each applicable Escrow Agent and (b) each Escrow Agent, upon the Depositary receiving such amount, has agreed to deliver escrow receipts to be affixed to each Certificate;

WHEREAS, prior to the delivery of each Aircraft, the Company will determine whether to enter into a leveraged lease transaction as lessee with respect to such Aircraft (a "Leased Aircraft") or to purchase as owner such Aircraft (an "Owned Aircraft"), and will give to the Pass Through Trustee a Delivery Notice (as defined below) specifying its election;

WHEREAS, concurrently with the execution and delivery of this Agreement, (i) Westdeutsche Landesbank Girozentrale, a German banking institution organized under the law of the State of North Rhine-Westphalia, acting through its New York Branch, entered into a revolving credit agreement for the benefit of the Certificateholders of the Class A Pass Through Trust and Morgan Stanley Capital Services, Inc. entered into two revolving credit agreements for the benefit of the Certificateholders of the Class B Pass Through Trust and the Class C Pass Through Trust, in each case with the Subordination Agent, as agent for the Pass Through Trustee on behalf of each such Pass Through Trust (Westdeutsche Landesbank Girozentrale, New York Branch, and Morgan Stanley Capital Services, Inc. are collectively referred to herein as the "Liquidity Providers", and the revolving credit agreements as the "Liquidity Facilities") and (ii) the Pass Through Trustee, the Liquidity Providers and the Subordination Agent entered into the Intercreditor Agreement, dated as of the date hereof (the "Intercreditor Agreement");

NOW, THEREFORE, in consideration of the foregoing premises and the mutual agreements herein contained and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Financing of Aircraft. (a) The Company confirms that it has entered into the Purchase Agreement with the Manufacturer pursuant to which the Company has agreed to purchase, and the Manufacturer has agreed to deliver, the Aircraft, all on and subject to terms and conditions specified in the Purchase Agreement. The currently scheduled delivery dates for the Aircraft are set forth in Schedule 1. The Company agrees to finance the Aircraft in

2

the manner provided herein, all on and subject to the terms and conditions hereof and of the relevant Financing Agreements.

(b) In furtherance of the foregoing, the Company agrees to give the parties hereto, the Depositary and each of the Rating Agencies and DCR not less than two Business Days' prior notice (a "Delivery Notice") of the scheduled delivery date (the "Scheduled Delivery Date") (or, in the case of a substitute Delivery Notice under Section 1(d) or (e) hereof, one Business Day's prior notice) in respect of each Aircraft under the Purchase Agreement, which notice shall:

(i) specify whether the Company has elected to treat such Aircraft as a Leased Aircraft or an Owned Aircraft;

(ii) specify the Scheduled Delivery Date of such Aircraft (which shall be a Business Day before the Cut-off Date and, except as provided in Section 1(e) hereof, the date (the "Funding Date") on which the financing therefor in the manner provided herein shall be consummated);

(iii) instruct the Pass Through Trustee to instruct the relevant Escrow Agent to provide a Notice of Purchase Withdrawal to the Depositary with respect to the Equipment Notes to be issued in connection with the financing of such Aircraft;

(iv) instruct the Pass Through Trustee to enter into the Participation Agreement included in the Financing Agreements with respect to such Aircraft in such form and at such a time on or before the Funding Date specified in such Delivery Notice and to perform its obligations thereunder;

(v) specify the aggregate principal amount of each series of Equipment Notes to be issued, and purchased by the Pass Through Trustee, in connection with the financing of such Aircraft scheduled to be delivered on such Funding Date (which shall in all respects comply with the Mandatory Economic Terms); and

(vi) if such Aircraft is to be a Leased Aircraft, certify that the related Owner Participant (A) is not an Affiliate of the Company (unless prior Rating Agency Confirmation permitting the use of an Affiliate has been obtained) and (B) based on the representations of such Owner Participant, is either (1) a Qualified Owner Participant or
(2) any other person the obligations of which under the Owner Participant Agreements (as defined in the applicable Participation Agreement) are guaranteed by a Qualified Owner Participant.

(c) Upon receipt of a Delivery Notice, the Pass Through Trustees shall, and shall cause the Subordination Agent to, enter into and perform their obligations under the Participation Agreement specified in such Delivery Notice, provided that, (i) the relevant Financing Agreements as executed and delivered shall not vary the Mandatory Economic Terms and shall contain the Mandatory Document Terms and (ii) subject to the next two succeeding sentences, such Participation Agreement and the other Lease Financing Agreements or Owner

3

Financing Agreements to be entered into pursuant to such Participation Agreement shall be in the forms thereof annexed hereto in all material respects. The Leased Aircraft Participation Agreements and other Lease Financing Agreements may contain modifications, provided, however, that with respect to any material modifications (other than modifications affecting only the Owner Participant), a Rating Agency Confirmation shall have been obtained from each Rating Agency by the Company and delivered by the Company to the applicable Pass Through Trustee on or before the relevant Delivery Date. If Rating Agency Confirmation shall have been received with respect to any Financing Agreements and such Financing Agreements are utilized for subsequent Aircraft (or Substitute Aircraft) without material modifications, no additional Rating Agency Confirmation shall be required. Notwithstanding the foregoing, if any Financing Agreement annexed hereto shall not have been reviewed by either Rating Agency prior to the Issuance Date, then, prior to the use thereof in connection with the financing of any Aircraft hereunder, the Company shall obtain from each Rating Agency a confirmation that the use of such Financing Documents would not result in (x) a reduction of the rating for any Class of Certificates below the then current rating for such Class of Certificates or (y) a withdrawal or suspension of the rating of any Class of Certificates. With respect to each Aircraft, the Company shall cause Wilmington Trust Company (or such other person that meets the eligibility requirements to act as loan trustee under the Leased Aircraft Indenture or Owned Aircraft Indenture) to execute as Loan Trustee the Financing Agreements relating to such Aircraft to which such Loan Trustee is intended to be a party, and shall concurrently therewith execute such Financing Agreements to which the Company is intended to be a party and perform its respective obligations thereunder. Upon the request of either Rating Agency or of DCR, the Company shall deliver or cause to be delivered to such requesting entity a true and complete copy of each Financing Agreement relating to the financing of each Aircraft together with a true and complete set of the closing documentation (including legal opinions) delivered to the related Loan Trustee, Subordination Agent and Pass Through Trustee under the related Participation Agreement.

(d) If after giving any Delivery Notice, there shall be a delay in the delivery of an Aircraft, or if on the Scheduled Delivery Date of an Aircraft the financing thereof in the manner contemplated hereby shall not be consummated for whatever reason, the Company shall give the parties hereto prompt notice thereof. Concurrently with the giving of such notice of postponement or subsequently, the Company shall give the parties hereto a substitute Delivery Notice specifying the date to which such delivery and related financing shall have been re-scheduled (which shall be a Business Day before the Cut-off Date on which the Escrow Agents shall be entitled to withdraw all or a portion of the Deposit under each of the applicable Deposit Agreements to enable each applicable Pass Through Trustee to fund its purchase of the related Equipment Notes). Upon receipt of any such notice of postponement, each applicable Pass Through Trustee shall comply with its obligations under Section 5.01 of each of the Trust Supplements and thereafter the financing of the relevant Aircraft shall take place on the re-scheduled Delivery Date therefor (all on and subject to the terms and conditions of the relevant Financing Agreements) unless further postponed as provided herein.

(e) Anything in this Section 1 to the contrary notwithstanding, the Company shall have the right at any time on or before the Scheduled Delivery Date of any Aircraft, and subsequent to its giving a Delivery Notice therefor, to postpone the Scheduled Delivery Date of

4

such Aircraft so as to enable the Company to change its election to treat such Aircraft as a Leased Aircraft or an Owned Aircraft by written notice of such postponement to the other parties hereto. The Company shall subsequently give the parties hereto a substitute Delivery Notice complying with the provisions of
Section 1(b) hereof and specifying the new Funding Date for such postponed Aircraft (which shall be a Business Day occurring before the Cut-off Date and on which the Escrow Agents shall be entitled to withdraw the Deposit under each of the applicable Deposit Agreements sufficient to enable each applicable Pass Through Trustee to fund its purchase of the related Equipment Notes). In addition, the Company shall have the further right, anything in this Section 1 to the contrary notwithstanding, to accept delivery of an Aircraft under the Purchase Agreement on the Delivery Date thereof by utilization of bridge financing of such Aircraft and promptly thereafter give the parties hereto a Delivery Notice specifying a Funding Date not later than 60 days after the Delivery Date of such Aircraft and no later than the Cut-off Date and otherwise complying with the provisions of Section 1(b) hereof. All other terms and conditions of this Note Purchase Agreement shall apply to the financing of any such Aircraft on the re-scheduled Funding Date therefor except (i) the re-scheduled Funding Date shall be deemed the Delivery Date of such Aircraft for all purposes of this Section 1 and (ii) the related Financing Agreements shall be amended to reflect the original delivery of such Aircraft to the Company.

(f) If the Scheduled Delivery Date for any Aircraft is delayed
(a) more than 30 days beyond the last day of the month set forth opposite such Aircraft under the heading "Scheduled Delivery Months" in Schedule I hereto or
(b) beyond the Delivery Period Termination Date, the Company may identify for delivery a substitute aircraft therefor meeting the following conditions (a "Substitute Aircraft"): (i) a Substitute Aircraft must be a Boeing 747-400F aircraft manufactured after 1993, so long as after giving effect thereto such substitution does not vary the Mandatory Economic Terms, and (ii) the Company shall be obligated to obtain Rating Agency Confirmation in respect of the replacement of any Aircraft by Substitute Aircraft. Upon the satisfaction of the conditions set forth above with respect to a Substitute Aircraft, the Aircraft to be replaced shall cease to be subject to this Agreement and all rights and obligations of the parties hereto concerning such Aircraft shall cease, and such Substitute Aircraft shall become and thereafter be subject to the terms and conditions of this Agreement to the same extent as such Aircraft.

(g) The Company shall have no liability for the failure of any Pass Through Trustee to purchase Equipment Notes with respect to any Aircraft or Substitute Aircraft, other than the Company's obligation, if any, to pay the Deposit Make-Whole Premium pursuant to Section 4(a)(i) of this Agreement.

(h) The parties agree that if, in connection with the delivery of an Aircraft or Substitute Aircraft, any Owner Participant who is to be a party to any Lease Financing Agreement shall not be a "Citizen of the United States" within the meaning of Section 40102(a)(15) of the Act, then the applicable Lease Financing Agreements shall be modified, consistent with the Mandatory Document Terms, to require such Owner Participant to enter into a voting trust, voting powers, control rights or similar arrangement satisfactory to the Company that (A) enables such Aircraft or Substitute Aircraft to be registered in the United States and (B) complies with the FAA regulations issued under the Act applicable thereto.

5

(i) Anything herein to the contrary notwithstanding, the Company shall not have the right, and shall not be entitled, at any time to request the issuance of Equipment Notes of any series to any Pass Through Trustee in an aggregate principal amount in excess of the amount of the Deposit then available for withdrawal in respect of such Equipment Notes by the Escrow Agent under and in accordance with the provisions of the related Deposit Agreement.

SECTION 2. Conditions Precedent. The obligation of the Pass Through Trustees to enter into, and to cause the Subordination Agent to enter into, any Participation Agreement as directed pursuant to a Delivery Notice and to perform its obligations under such Participation Agreement is subject to satisfaction of the following conditions:

(a) no Triggering Event shall have occurred; and

(b) the Company shall have delivered to each such Pass Through Trustee and each Liquidity Provider a certificate stating that (i) such Participation Agreement and the other Financing Agreements to be entered into pursuant to such Participation Agreement do not vary the Mandatory Economic Terms and contain the Mandatory Document Terms and
(ii) any substantive modification of such Financing Agreements from the forms thereof attached to this Agreement do not materially and adversely affect the Certificateholders, and such certification shall be true and correct.

Anything herein to the contrary notwithstanding, the obligation of each Pass Through Trustee to purchase Equipment Notes shall terminate on the Cut-off Date.

Such Note Holder (if it is a Non-U.S. Person) agrees to indemnify (on an after-tax basis) and hold harmless Lessee, Lessor, Owner Participant and Mortgagee against any United States withholding taxes (and related interest, penalties and additions to tax) as a result of the inaccuracy or invalidity of any certificate or form provided by such Note Holder to Mortgagee in connection with such withholding taxes. Any amount payable hereunder shall be paid within 30 days after receipt by a Note Holder of a written demand therefor.

7.5.2 TRANSFER; COMPLIANCE

(a) Such Note Holder will (i) not transfer any Equipment Note or interest therein in violation of the Securities Act or applicable state or foreign securities Law; provided, that the foregoing provisions of this section shall not be deemed to impose on such Note Holder any responsibility with respect to any such offer, sale or solicitation by any other party hereto, and (ii) perform and comply with the obligations specified to be imposed on it (as a Note Holder) under each of the Trust Indenture and the form of Equipment Note set forth in the Trust Indenture.

(b) Except as otherwise required by the terms of Section 2.13 of the Trust Indenture or Section 11 hereof, each Note Holder will not sell, assign, convey, exchange or otherwise transfer any Equipment Note or any interest in, or represented by, any Equipment Note (it being understood that this provision is not applicable to the Pass Through Certificates) unless the proposed transferee thereof first provides Lessee and Owner Participant with both of the following:


-41-

(i) a written representation and covenant that either (a) no portion of the funds it uses to purchase, acquire and hold such Equipment Note or interest directly or indirectly constitutes, or may be deemed under the Code or ERISA or any rulings, regulations or court decisions thereunder to constitute, the assets of any Plan or (b) the transfer, and subsequent holding, of such Equipment Note or interest shall not involve or give rise to a transaction that constitutes a prohibited transaction within the meaning of Section 406 of ERISA or Section 4975(c)(1) of the Code involving Lessee, Owner Participant, a Pass Through Trustee, the Subordination Agent or the proposed transferee (other than a transaction that is exempted from the prohibitions of such sections by applicable provisions of ERISA or the Code or administrative exemptions or regulations issued thereunder); and

(ii) a written covenant that it will not transfer any Equipment Note or any interest in, or represented by, any Equipment Note unless the subsequent transferee also makes the representation described in clause (i) above and agrees to comply with this clause (ii).

7.6 AGREEMENTS

7.6.1 OWNER TRUSTEE IS OWNER AND LESSOR FOR ALL PURPOSES

Lessee, the Owner Participant and Owner Trustee agree that for all purposes, after the Closing, Owner Trustee will be the owner and lessor of the Aircraft (except that Owner Participant will be the owner and lessor for income tax purposes) and Lessee will be the lessee thereof. No transfer, by operation of Law or otherwise, of the beneficial interest of Owner Participant in and to the Trust Estate shall operate to transfer legal title to any part of the Trust Estate to any transferee thereof.

7.6.2 COMMENCEMENT OF BANKRUPTCY PROCEEDINGS

Lessee, each Participant, each Note Holder, First Security, Owner Trustee, WTC and Mortgagee agree for the benefit of each of the others that it will not commence or join in any proceeding under the Bankruptcy Code to commence a case under Section 303 of the Bankruptcy Code against the Trust Estate. Nothing contained herein shall be deemed to preclude any Participant, any Note Holder, First Security, Owner Trustee, WTC


-42-

or Mortgagee from filing any claim against the Trust Estate in any case commenced against the Trust Estate.

7.6.3 CERTAIN BANKRUPTCY MATTERS

If (a) all or any part of the Trust Estate becomes the property of, or Owner Trustee or Owner Participant becomes, a debtor subject to the reorganization provisions of the Bankruptcy Code, (b) pursuant to such reorganization provisions, including Section 1111(b) of the Bankruptcy Code, First Security or Owner Participant is required, by reason of First Security or Owner Participant being held to have recourse liability to any Note Holder or Mortgagee directly or indirectly (other than the recourse liability of First Security or Owner Participant under this Agreement, the Trust Indenture or by separate agreement), to make payment on account of any amount payable as principal, Make-Whole Amount, if any, interest or other amounts on the Equipment Notes, and (c) any Note Holder or Mortgagee actually receives any Excess Amount, as defined below, which reflects any payment by First Security or Owner Participant on account of (b) above, then such Note Holder or Mortgagee, as the case may be, shall promptly refund to First Security or Owner Participant (whichever shall have made such payment) such Excess Amount.

For purposes of this Section 7.6.3, "Excess Amount" means the amount by which such payment exceeds the amount that would have been received by a Note Holder or Mortgagee if First Security or Owner Participant had not become subject to the recourse liability referred to in clause (b) above. Nothing contained in this Section 7.6.3 shall prevent a Note Holder or Mortgagee from enforcing any personal recourse obligation (and retaining the proceeds thereof) of First Security or Owner Participant under this Agreement (other than as referred to in clause (b) above) or the Trust Indenture (and any exhibits or annexes thereto) or from retaining any amount paid by Owner Participant under Sections 2.13 or 4.03 of the Trust Indenture.

7.6.4 QUIET ENJOYMENT; SALE BY OWNER TRUSTEE BINDING

(a) Owner Participant, each Pass Through Trustee, Subordination Agent, each Note Holder, Owner Trustee and Mortgagee each agrees as to itself with Lessee that, so long as no Lease Event of Default shall have occurred and be continuing, such Person shall not (and shall not permit any Affiliate or other Person claiming by, through or under it to) interfere with Lessee's or any Permitted Sublessee's rights in accordance with the Lease to the quiet enjoyment, possession and use of the Aircraft during the Term.


-43-

(b) Any assignment, sale, transfer or other conveyance of the Aircraft by Owner Trustee made pursuant to the terms of this Agreement or the Lease shall bind Owner Participant and shall be effective to transfer or convey all right, title and interest of Owner Trustee and Owner Participant in and to the Aircraft. No purchaser or other grantee shall be required to inquire as to the authorization, necessity, expediency or regularity of such assignment, sale, transfer or conveyance, or as to the application of any sale or other proceeds with respect thereto by Owner Trustee, as regards Owner Participant.

7.6.5 RELEASE OF LIEN OF TRUST INDENTURE

Each of Lessee, Lessor and Mortgagee agrees that in each instance referred to in the Lease in which a transfer of any property is required to be made by Lessor to Lessee or any other Person (other than Mortgagee), Mortgagee shall, upon request of Lessor and compliance with the applicable provisions of the Lease and the Trust Indenture, including payment of all amounts then due and payable to each Liquidity Provider as Supplemental Rent, promptly execute (at Lessee's cost and expense) such instruments as Lessor or Lessee may reasonably request to evidence the release of the Lien of the Trust Indenture with respect to such property.

7.6.6 NON-RECOURSE

Each Loan Participant and Mortgagee agrees that (a) obligations of Owner Trustee under the Trust Indenture or any other Operative Agreement and with respect to the Equipment Notes shall be non-recourse to Owner Participant and to First Security and (b) they will look solely to the income and proceeds from the Trust Estate and the Trust Indenture Estate to the extent available for distribution to Note Holder or Mortgagee as provided in the Trust Indenture and that neither Owner Participant nor First Security will be personally liable to Loan Participant or Mortgagee for any amounts payable by Owner Trustee under the Trust Indenture or any other Operative Agreement; provided, however, that the foregoing is not intended nor shall it be construed to limit any recourse liability of Owner Participant or First Security to the extent that such liability is expressly set forth in this Agreement or in any of the Operative Agreements or arises by reason of the breach of any


-44-

representation or warranty or covenant given by such Person (in the case of First Security, in its individual capacity).

7.6.7 OTHER DOCUMENTS; AMENDMENT

(a) So long as the Lease has not been terminated or expired, each Participant, the Mortgagee and the Owner Trustee hereby agree for the benefit of Lessee that without the consent of Lessee they will not amend, supplement or otherwise modify (i) Article III, Article IX or Section 2.05 of the Trust Indenture, (ii) any provision of any Operative Agreement that will affect the stated principal amount of or premium or interest on the Equipment Notes or (iii) any other provision of the Trust Indenture or Equipment Notes in a manner that would adversely affect Lessee. Mortgagee and Owner Trustee agree to promptly furnish to Lessee copies of any supplement, amendment, waiver or modification of any of the Operative Agreements to which Lessee is not a party; provided that Mortgagee or Owner Trustee, as the case may be, has in its possession a copy of such supplement, amendment, waiver or modification. Each Loan Participant agrees that it will not take any action in respect of the Trust Indenture Estate except through the Mortgagee pursuant to the Trust Indenture or as otherwise permitted by Trust Indenture or other Operative Agreement.

(b) Owner Trustee agrees to join with Lessee to the extent that action on the part of Owner Trustee is necessary or appropriate (i) to cause the following to be duly accomplished in accordance with applicable United States federal Law by the time the Aircraft is delivered under this Agreement and the Lease: (A) the application for registration of the Aircraft in the name of Owner Trustee and (B) all related action necessary in order for Lessee to have temporary or permanent authority to operate the Aircraft as contemplated by the Lease and (ii) forthwith upon delivery of the Aircraft under this Agreement and the Lease, to cause all necessary documents to be duly filed for recording in accordance with applicable United States federal Law.

7.6.8 CONSENTS

Each of Owner Participant, each Pass Through Trustee, Subordination Agent, Owner Trustee and Mortgagee covenants and agrees, for the benefit of Lessee, that it shall not unreasonably withhold its consent to any consent or approval requested


-45-

of it or of Owner Trustee or Mortgagee under the terms of any of the Operative Agreements which by its terms is not to be unreasonably withheld.

7.6.9 INSURANCE

Each of Owner Participant, the Pass Through Trustees, the Subordination Agent and the Owner Trustee agrees not to obtain or maintain insurance for its own account as permitted by Section 11.2 of the Lease if such insurance would limit or otherwise adversely affect the coverage of any insurance required to be obtained or maintained by Lessee pursuant to Section 11 and Annex D of the Lease.

7.6.10 EXTENT OF INTEREST OF NOTE HOLDERS

A Note Holder shall not, as such, have any further interest in, or other right with respect to, the Trust Estate or the Trust Indenture Estate when and if the principal and Make-Whole Amount, if any, of and interest on the Equipment Note held by such Note Holder, and all other sums, then due and payable to such Note Holder hereunder and under any other Operative Agreement, shall have been paid in full.

7.6.11 FOREIGN REGISTRATION

Each Participant, Owner Trustee and Mortgagee hereby agree, for the benefit of Lessee but subject to the provisions of Section 7.1.2 of the Lease:

(a) that Lessee shall be entitled to register the Aircraft or cause the Aircraft to be registered in a country other than the United States subject to compliance with the following:

(i) each of the following requirements is satisfied:

(A) such registration shall be made only after the close of the Tax Attribute Period, unless Lessee prepays to the Owner Participant on a lump sum basis any indemnity due under the Tax Indemnity Agreement as a result of such registration based upon the assumption that such registration would continue for the remainder of the term of the Permitted Sublease described in clause (C) below;


-46-

(B) no Lease Event of Default shall have occurred and be continuing at the time of such registration;

(C) such proposed change of registration is made in connection with a Permitted Sublease to a Permitted Air Carrier;

(D) such country is a Permitted Country with which the United States then maintains normal diplomatic relations or, if Taiwan, the United States then maintains diplomatic relations at least as good as those in effect on the Delivery Date;

(ii) the Owner Trustee and Mortgagee shall have received an opinion of counsel (subject to customary exceptions) reasonably satisfactory to the Owner Participant addressed to each such party as to the effect that:

(A) such country would recognize the Owner Trustee's ownership interest in the Aircraft;

(B) the obligations of Lessee, and the rights and remedies of Owner Trustee, under the Lease are valid, binding and enforceable under the laws of such jurisdiction (or the laws of the jurisdiction to which the laws of such jurisdiction would refer as the applicable governing law);

(C) after giving effect to such change in registration, the Lien of the Trust Indenture on the Owner Trustee's right, title and interest in and to the Aircraft and the Lease shall continue as a valid and duly perfected first priority security interest and all filing, recording or other action necessary to protect the same shall have been accomplished (or, if such opinion cannot be given at the time of such proposed change in registration because such change in registration is not yet effective, (1) the opinion shall detail what filing, recording or other action is necessary and (2) the Owner Trustee and the Mortgagee shall have received a certificate from Lessee that all possible preparations to accomplish such filing, recording and other action shall have been done, and such filing, recording and other action shall be accomplished and a supplemental opinion to that effect shall be delivered to the Owner Trustee


-47-

and the Mortgagee on or prior to the effective date of such change in registration);

(D) it is not necessary, solely as a consequence of such change in registration and without giving effect to any other activity of the Owner Trustee, the Owner Participant or the Mortgagee (or any Affiliate thereof), as the case may be, for the Owner Trustee, the Owner Participant or the Mortgagee to qualify to do business in such jurisdiction as a result of such reregistration in order to exercise any rights or remedies with respect to the Aircraft pursuant to the Lease;

(E) there is no tort liability of the owner or lessor of an aircraft not in possession thereof under the laws of such jurisdiction (it being agreed that, in the event such opinion cannot be given in a form satisfactory to the Owner Participant, such opinion shall be waived if insurance reasonably satisfactory to the Owner Participant is provided to cover such risk); and

(F) unless Lessee shall have agreed to provide insurance covering the risk of requisition of use of the Aircraft by the government of such country (so long as the Aircraft is registered under the laws of such country), the laws of such country require fair compensation by the government of such country payable in currency freely convertible into Dollars and freely removable from such country (without license or permit, unless Lessee prior to such proposed reregistration has obtained such license or permit) for the taking or requisition by such government of such use;

(b) In addition, as a condition precedent to any change in registration Lessee shall have given to Lessor and Mortgagee assurances reasonably satisfactory to each of them:

(i) to the effect that the provisions of Section 11 of the Lease will have been complied with after giving effect to such change of registration;

(ii) of the payment by Lessee of all reasonable out-of-pocket expenses of Lessor, each Participant and Mortgagee in connection with such change of registry, including,


-48-

without limitation (1) the reasonable fees and disbursements of counsel to Lessee, Lessor and Mortgagee, (2) any filing or recording fees, Taxes or similar payments incurred in connection with the change of registration of the Aircraft and the creation and perfection of the security interest therein in favor of Mortgagee for the benefit of Note Holders, and (3) all costs and expenses incurred in connection with any filings necessary to continue in the United States the perfection of the security interest in the Aircraft and the Lease in favor of Mortgagee for the benefit of Note Holders; and

(iii) to the effect that the tax and other indemnities in favor of each person named as an indemnitee under any other Operative Agreement afford each such person substantially the same protection as provided prior to such change of registration (or Lessee shall have agreed upon additional indemnities that, together with such original indemnities, in the reasonable judgment of Lessor and Mortgagee, afford such protection).

7.6.12 OTHER COMMERCIAL RELATIONS UNAFFECTED

Notwithstanding anything to the contrary set forth in any Operative Agreement:

(a) Except as set forth in the Purchase Agreement Assignment, nothing contained in the Operative Agreements shall constitute or be deemed to be a waiver by Lessee of any rights, remedies or claims it may have against Airframe Manufacturer or Engine Manufacturer or any subcontractor or supplier of either; and the Operative Agreements do not and shall not be construed or deemed to create any rights, waivers, immunities or indemnities in favor of Airframe Manufacturer, Engine Manufacturer or any subcontractor or supplier of either with respect to any such rights, remedies or claims of Lessee; and

(b) None of Airframe Manufacturer, by its execution and delivery of the Consent and Agreement, and Engine Manufacturer, by its execution and delivery of the Engine Consent and Agreement, shall be deemed to have waived any rights, remedies or claims which Airframe Manufacturer or Engine Manufacturer (or any subcontractor or supplier of either), as the case may be, may have against Lessee; and the Operative Agreements do not and shall not be construed or deemed to create any rights, waivers, immunities or indemnities in favor of Lessee with respect to any such


-49-

rights, remedies or claims of Airframe Manufacturer or Engine Manufacturer (or any subcontractor or supplier of either).

7.6.13 INTEREST IN CERTAIN ENGINES

-56-

9.1.5 NOTICE OF PROCEEDINGS; DEFENSE OF CLAIMS; LIMITATIONS

(a) In case any action, suit or proceeding shall be brought against any Indemnitee for which Lessee is responsible under this Section 9.1, such Indemnitee shall notify Lessee of the commencement thereof and Lessee may, at its expense, participate in and to the extent that it shall wish (subject to the provisions of the following paragraph), assume and control the defense thereof and, subject to Section 9.1.5(c), settle or compromise the same.

(b) Lessee or its insurer(s) shall have the right, at its or their expense, to investigate or, if Lessee or its insurer(s) shall agree not to dispute liability to the Indemnitee giving notice of such action, suit or proceeding under this Section 9.1.5 for indemnification hereunder or under any insurance policies pursuant to which coverage is sought, control the defense of, any action, suit or proceeding, relating to any Expense for which indemnification is sought pursuant to this Section 9.1, and each Indemnitee shall cooperate with Lessee or its insurer(s) with respect thereto; provided, that Lessee shall not be entitled to control the defense of any such action, suit, proceeding or compromise any such Expense during the continuance of any Lease Event of Default arising under Section 14.1 of the Lease. In connection with any such action, suit or proceeding being controlled by Lessee, such Indemnitee shall have the right to participate therein, at its sole cost and expense, with counsel reasonably satisfactory to Lessee; provided, that such Indemnitee's participation does not, in the reasonable opinion of the independent counsel appointed by the Lessee or its insurers to conduct such proceedings, interfere with the defense of such case.

(c) In no event shall any Indemnitee enter into a settlement or other compromise with respect to any Expense without the prior written consent of Lessee, which consent shall not be unreasonably withheld or delayed. Any settlement or compromise without such consent of Lessee shall be deemed a waiver by such Indemnitee of its right to be indemnified with respect to such Expense under this Section 9.1.

(d) In the case of any Expense indemnified by the Lessee hereunder which is covered by a policy of insurance maintained by Lessee pursuant to
Section 11 of the Lease,


-57-

at Lessee's expense, each Indemnitee agrees to cooperate with the insurers in the exercise of their rights to investigate, defend or compromise such Expense as may be required to retain the benefits of such insurance with respect to such Expense.

(e) If an Indemnitee is not a party to this Agreement, Lessee may require such Indemnitee to agree in writing to the terms of this Section 9 and Section 15.8 prior to making any payment to such Indemnitee under this
Section 9.

(f) Nothing herein shall be deemed to be an assumption by Lessee of obligations of Owner Trustee with respect to, or a guarantee by Lessee of, any amounts payable by Owner Trustee upon Equipment Notes or a guarantee of any residual value of the Aircraft.

9.1.6 INFORMATION

Lessee will provide the relevant Indemnitee with such information not within the control of such Indemnitee, as is in Lessee's control or is reasonably available to Lessee, which such Indemnitee may reasonably request and will otherwise cooperate with such Indemnitee so as to enable such Indemnitee to fulfill its obligations under Section 9.1.5. The Indemnitee shall supply Lessee with such information not within the control of Lessee, as is in such Indemnitee's control or is reasonably available to such Indemnitee, which Lessee may reasonably request to control or participate in any proceeding to the extent permitted by Section 9.1.5.

9.3 GENERAL TAX INDEMNITY

9.3.1 GENERAL

Except as provided in Section 9.3.2, Lessee agrees that each payment of Rent paid by Lessee pursuant to the Lease, and any other payment or indemnity paid by Lessee to a Tax Indemnitee under any Operative Agreement, shall be free of all withholdings or deductions with respect to Taxes of any nature (other than U.S. federal, state or local withholding taxes on, based on or measured by gross or net income), and in the event that Lessee shall be required by applicable law to make any such withholding or deduction for any such payment
(x) Lessee shall make all such withholdings or deductions, (y) the amount payable by Lessee shall be increased so that after making all required withholdings or deductions such Tax Indemnitee receives the same amount that it would have received had no such withholdings or deductions been made, and (z) Lessee shall pay the full amount withheld or deducted to the relevant Taxing Authority in accordance with applicable law. Lessee further agrees that, in the event it is required to withhold from any payment of Basic Rent, Stipulated Loss Value (and amounts determined by reference thereto), and amounts payable upon exercise

9.3.3 PAYMENT

(a) Lessee's indemnity obligation to a Tax Indemnitee under this
Section 9.3 shall equal the amount which, after taking into account any Tax imposed upon the receipt or accrual of the amounts payable under this
Section 9.3 and any tax benefits actually recognized by such Tax Indemnitee as a result of the indemnifiable Tax (including, without limitation, any benefits recognized as a result of an indemnifiable Tax being utilized by such Tax Indemnitee as a credit against Taxes not indemnifiable under this
Section 9.3), shall equal the amount of the Tax indemnifiable under this
Section 9.3.

(b) At Lessee's request, the computation of the amount of any indemnity payment owed by Lessee or any


-65-

amount owed by a Tax Indemnitee to Lessee pursuant to this Section 9.3 shall be verified and certified by an independent public accounting firm selected by such Tax Indemnitee and reasonably satisfactory to Lessee. Such verification shall be binding. The costs of such verification (including the fee of such public accounting firm) shall be borne by Lessee unless such verification shall result in an adjustment in Lessee's favor of 5% or more of the net present value of the payment as computed by such Tax Indemnitee, in which case the costs shall be paid by such Tax Indemnitee.

(c) Each Tax Indemnitee shall provide Lessee with such certifications, information and documentation as shall be in such Tax Indemnitee's possession and as shall be reasonably requested by Lessee to minimize any indemnity payment pursuant to this Section 9.3; provided, that notwithstanding anything to the contrary contained herein, no Tax Indemnitee shall be required to provide Lessee with any Tax returns.

(d) Each Tax Indemnitee shall promptly forward to Lessee any written notice, bill or advice received by it from any Taxing Authority concerning any Tax for which it seeks indemnification under this Section 9.3. Lessee shall pay any amount for which it is liable pursuant to this Section 9.3 directly to the appropriate Taxing Authority if legally permissible or upon demand of a Tax Indemnitee, to such Tax Indemnitee within 30 days of such demand (or, if a contest occurs in accordance with Section 9.3.4, within 30 days after a Final Determination (as defined below)), but in no event more than one Business Day prior to the date the Tax to which such amount payable hereunder relates is due. If requested by a Tax Indemnitee in writing, Lessee shall furnish to the appropriate Tax Indemnitee the original or a certified copy of a receipt for Lessee's payment of any Tax paid by Lessee or such other evidence of payment of such Tax as is acceptable to such Tax Indemnitee. Lessee shall also furnish promptly upon written request such data as any Tax Indemnitee may reasonably require to enable such Tax Indemnitee to comply with the requirements of any taxing jurisdiction unless such data is not reasonably available to Lessee or, unless such data is specifically requested by a Taxing Authority, is not customarily furnished by domestic air carriers under similar circumstances. For purposes of this Section 9.3, a "Final Determination" shall mean (i) a decision, judgment, decree or other order by any court of


-66-

competent jurisdiction that occurs pursuant to the provisions of Section 9.3.4, which decision, judgment, decree or other order has become final and unappealable, (ii) a closing agreement or settlement agreement entered into in accordance with Section 9.3.4 that has become binding and is not subject to further review or appeal (absent fraud, misrepresentation, etc.), or
(iii) the termination of administrative proceedings and the expiration of the time for instituting a claim in a court proceeding.

(e) If any Tax Indemnitee shall actually realize a tax savings by reason of any Tax paid or indemnified by Lessee pursuant to this Section
9.3 (whether such tax savings shall be by means of a foreign tax credit, depreciation or cost recovery deduction or otherwise) and such savings is not otherwise taken into account in computing such payment or indemnity such Tax Indemnitee shall pay to Lessee an amount equal to the lesser of
(i) the amount of such tax savings, plus any additional tax savings recognized as the result of any payment made pursuant to this sentence, when, as, if, and to the extent, realized or (ii) the amount of all payments pursuant to this Section 9.3 by Lessee to such Tax Indemnitee (less any payments previously made by such Tax Indemnitee to Lessee pursuant to this Section 9.3.3 (e)) (and the excess, if any, of the amount described in clause (i) over the amount described in clause (ii) shall be carried forward and applied to reduce pro tanto any subsequent obligations of Lessee to make payments to such Tax Indemnitee pursuant to this Section 9.3); provided, that such Tax Indemnitee shall not be required to make any payment pursuant to this sentence so long as a Lease Event of Default of a monetary nature has occurred and is continuing. If a tax benefit is later disallowed or denied, the disallowance or denial shall be treated as a Tax indemnifiable under Section 9.3.1 without regard to the provisions of
Section 9.3.2 (other than Section 9.3.2 (f)). Each such Tax Indemnitee shall in good faith use reasonable efforts in filing its tax returns and in dealing with Taxing Authorities to seek and claim any such tax benefit.

9.3.4 CONTEST

(a) If a written claim is made against a Tax Indemnitee for Taxes with respect to which Lessee could be liable for payment or indemnity hereunder, or if a Tax Indemnitee makes a determination that a Tax is due for which Lessee could have an indemnity obligation hereunder, such


-67-

Tax Indemnitee shall promptly give Lessee notice in writing of such claim (provided, that failure to so notify Lessee shall not relieve Lessee of its indemnity obligations hereunder unless such failure to notify effectively forecloses Lessee's rights to require a contest of such claim) and shall take no action with respect to such claim without the prior written consent of Lessee for 30 days following the receipt of such notice by Lessee; provided, that, in the case of a claim made against a Tax Indemnitee, if such Tax Indemnitee shall be required by law to take action prior to the end of such 30-day period, such Tax Indemnitee shall, in such notice to Lessee, so inform Lessee, and such Tax Indemnitee shall take no action for as long as it is legally able to do so (it being understood that a Tax Indemnitee shall be entitled to pay the Tax claimed and sue for a refund prior to the end of such 30-day period if (i)(A) the failure to so pay the Tax would result in substantial penalties (unless immediately reimbursed by Lessee) and the act of paying the Tax would not materially prejudice the right to contest or (B) the failure to so pay would result in criminal penalties and (ii) such Tax Indemnitee shall take any action so required in connection with so paying the Tax in a manner that is the least prejudicial to the pursuit of the contest). In addition, such Tax Indemnitee shall (provided, that Lessee shall have agreed to keep such information confidential other than to the extent necessary in order to contest the claim) furnish Lessee with copies of any requests for information from any Taxing Authority relating to such Taxes with respect to which Lessee may be required to indemnify hereunder. If requested by Lessee in writing within 30 days after its receipt of such notice, such Tax Indemnitee shall, at the expense of Lessee (including, without limitation, all reasonable costs, expenses and reasonable attorneys' and accountants' fees and disbursements), in good faith contest (or, if permitted by applicable law, allow Lessee to contest) through appropriate administrative and judicial proceedings the validity, applicability or amount of such Taxes by (I) resisting payment thereof, (II) not paying the same except under protest if protest is necessary and proper or (III) if the payment is made, using reasonable efforts to obtain a refund thereof in an appropriate administrative and/or judicial proceeding. If requested to do so by Lessee, the Tax Indemnitee shall appeal any adverse administrative or judicial decision, except that the Tax Indemnitee shall not be required to pursue any appeals to the United States Supreme Court. If and to the extent the Tax Indemnitee is able to separate


-68-

the contested issue or issues from other issues arising in the same administrative or judicial proceeding that are unrelated to the transactions contemplated by the Operative Agreements without, in the good faith judgment of such Tax Indemnitee, adversely affecting such Tax Indemnitee, such Tax Indemnitee shall permit Lessee to control the conduct of any such proceeding and shall provide to Lessee (at Lessee's cost and expense) with such information or data that is in such Tax Indemnitee's control or possession that is reasonably necessary to conduct such contest. In the case of a contest controlled by a Tax Indemnitee, such Tax Indemnitee shall consult with Lessee in good faith regarding the manner of contesting such claim and shall keep Lessee reasonably informed regarding the progress of such contest. A Tax Indemnitee shall not fail to take any action expressly required by this Section 9.3.4 (including, without limitation, any action regarding any appeal of an adverse determination with respect to any claim) or settle or compromise any claim without the prior written consent of the Lessee (except as contemplated by Section 9.3.4(b) or (c)).

(b) Notwithstanding the foregoing, in no event shall a Tax Indemnitee be required to pursue any contest (or to permit Lessee to pursue any contest) unless (i) Lessee shall have agreed to pay such Tax Indemnitee on demand all reasonable costs and expenses incurred by such Tax Indemnitee in connection with contesting such Taxes, including, without limitation, all reasonable out of pocket costs and expenses and reasonable attorneys' and accountants' fees and disbursements, (ii) if such contest shall involve the payment of the claim, Lessee shall advance the amount thereof (to the extent indemnified hereunder) plus interest, penalties and additions to tax with respect thereto that are required to be paid prior to the commencement of such contest on an interest-free after-Tax basis to such Tax Indemnitee (and such Tax Indemnitee shall promptly pay to the Lessee any net realized tax benefits resulting from such advance including any tax benefits resulting from making such payment), (iii) such Tax Indemnitee shall have reasonably determined that the action to be taken will not result in any material risk of forfeiture, sale or loss of the Aircraft (unless Lessee shall have made provisions to protect the interests of any such Tax Indemnitee in a manner reasonably satisfactory to such Tax Indemnitee) (provided, that such Tax Indemnitee agrees to notify Lessee in writing promptly after it becomes aware of any such risk), (iv) no Lease Event of Default shall have occurred and be


-69-

continuing unless Lessee has provided security for its obligations hereunder by advancing to such Tax Indemnitee before proceeding or continuing with such contest, the amount of the Tax being contested, plus any interest and penalties and an amount estimated in good faith by such Tax Indemnitee for expenses, and (v) prior to commencing any judicial action controlled by Lessee, Lessee shall have acknowledged its liability for such claim hereunder, provided that Lessee shall not be bound by its acknowledgment if the Final Determination articulates conclusions of law and fact that demonstrate that Lessee has no liability for the contested amounts hereunder. Notwithstanding the foregoing, if any Tax Indemnitee shall release, waive, compromise or settle any claim which may be indemnifiable by Lessee pursuant to this Section 9.3 without the written permission of Lessee, Lessee's obligation to indemnify such Tax Indemnitee with respect to such claim (and all directly related claims and claims based on the outcome of such claim) shall terminate, subject to Section 9.3.4(c), and subject to Section 9.3.4(c), such Tax Indemnitee shall repay to Lessee any amount previously paid or advanced to such Tax Indemnitee with respect to such claim, plus interest at the rate that would have been payable by the relevant Taxing Authority with respect to a refund of such Tax.

(c) Notwithstanding anything contained in this Section 9.3, a Tax Indemnitee will not be required to contest the imposition of any Tax and shall be permitted to settle or compromise any claim without Lessee's consent if such Tax Indemnitee (i) shall waive its right to indemnity under this Section 9.3 with respect to such Tax (and any directly related claim and any claim the outcome of which is determined based upon the outcome of such claim), (ii) shall pay to Lessee any amount previously paid or advanced by Lessee pursuant to this Section 9.3 with respect to such Tax, plus interest at the rate that would have been payable by the relevant Taxing Authority with respect to a refund of such Tax, and (iii) shall agree to discuss with Lessee the views or positions of any relevant Taxing Authority with respect to the imposition of such Tax.

9.3.5 REFUND

If any Tax Indemnitee shall receive a refund of, or be entitled to a credit against other liability for, all or any part of any Taxes paid, reimbursed or advanced by Lessee, such Tax Indemnitee shall pay to Lessee within 30 days of such receipt


-70-

an amount equal to the lesser of (a) the amount of such refund or credit plus any net tax benefit (taking into account any Taxes incurred by such Tax Indemnitee by reason of the receipt of such refund or realization of such credit) actually realized by such Tax Indemnitee as a result of any payment by such Tax Indemnitee made pursuant to this sentence (including this clause (a)) and (b) such tax payment, reimbursement or advance by Lessee to such Tax Indemnitee theretofore made pursuant to this Section 9.3 (and the excess, if any, of the amount described in clause (a) over the amount described in clause
(b) shall be carried forward and applied to reduce pro tanto any subsequent obligation of Lessee to make payments to such Tax Indemnitee pursuant to this
Section 9.3). If, in addition to such refund or credit, such Tax Indemnitee shall receive (or be credited with) an amount representing interest on the amount of such refund or credit, such Tax Indemnitee shall pay to Lessee within 30 days of such receipt or realization of such credit that proportion of such interest that shall be fairly attributable to Taxes paid, reimbursed or advanced by Lessee prior to the receipt of such refund or realization of such credit.

9.3.6 TAX FILING

If any report, return or statement is required to be filed with respect to any Tax which is subject to indemnification under this Section 9.3, Lessee shall timely file the same (except for any such report, return or statement which a Tax Indemnitee has timely notified the Lessee in writing that such Tax Indemnitee intends to file, or for which such Tax Indemnitee is required by law to file, in its own name); provided, that the relevant Tax Indemnitee shall furnish Lessee with any information in such Tax Indemnitee's possession or control that is reasonably necessary to file any such return, report or statement and is reasonably requested in writing by Lessee (it being understood that the Tax Indemnitee shall not be required to furnish copies of its actual tax returns, although it may be required to furnish relevant information contained therein). Lessee shall either file such report, return or statement and send a copy of such report, return or statement to such Tax Indemnitee, and Owner Trustee if the Tax Indemnitee is not Owner Trustee, or, where Lessee is not permitted to file such report, return or statement, it shall notify such Tax Indemnitee of such requirement and prepare and deliver such report, return or statement to such Tax Indemnitee in a manner satisfactory to such Tax Indemnitee within a reasonable time prior to the time such report, return or statement is to be filed.


-71-

9.3.7 FORMS

Each Tax Indemnitee agrees to furnish from time to time to Lessee or Loan Trustee or to such other person as Lessee or Loan Trustee may designate, at Lessee's or Loan Trustee's request, such duly executed and properly completed forms as may be necessary or appropriate in order to claim any reduction of or exemption from any withholding or other Tax imposed by any Taxing Authority, if
(x) such reduction or exemption is available to such Tax Indemnitee and (y) Lessee has provided such Tax Indemnitee with any information necessary to complete such form not otherwise reasonably available to such Tax Indemnitee.

9.3.8 NON-PARTIES

If a Tax Indemnitee is not a party to this Agreement, Lessee may require the Tax Indemnitee to agree in writing, in a form reasonably acceptable to Lessee, to the terms of this Section 9.3 and Section 15.8 prior to making any payment to such Tax Indemnitee under this Section 9.3.

9.3.9 SUBROGATION

Upon payment of any Tax or other amount computed by reference to the amount of any Tax by Lessee pursuant to this Section 9.3 to or on behalf of a Tax Indemnitee or any Affiliate thereof, Lessee, without any further action, shall be subrogated to any claims that such Tax Indemnitee or Affiliate may have relating thereto. Such Tax Indemnitee or Affiliate shall cooperate with Lessee (to the extent such cooperation does not result in any unreimbursed cost, expense or liability to such Tax Indemnitee or Affiliate) to permit Lessee to pursue such claims.

9.3.10 FOREIGN TAX ON LOAN PAYMENTS

If an Owner Participant is incorporated or organized, or maintains a place of business or conducts activities in, a country other than the United States or in a territory, possession or commonwealth of the United States (within the meaning of the tax law of that foreign jurisdiction) and if as a result thereof any foreign Taxes (including withholding Taxes) are imposed on the Pass Through Trustees, Pass Through Trusts, or Note Holders, then Owner Participant shall reimburse Lessee for any payments Lessee is required to make to or on behalf of any Pass Through Trustee, Pass Through Trust, or Note Holder under this Section 9.3 as a result of the imposition of such Taxes.


-72-

The amount payable by Owner Participant to Lessee shall be an amount which, after taking into account any such Taxes, any Tax imposed upon the receipt or accrual by Lessee of such payment by Owner Participant and any tax benefits or tax savings realized by Lessee with respect to the payment of such withholding Tax or the payment hereunder, shall equal the amount of Lessee's payment to or on behalf of such Pass Through Trustee, or Note Holder.

9.4 PAYMENTS

(iii) the Mortgagee shall have received an insurance report dated the effective date of such assumption of an independent insurance broker and certificates of insurance, each in form and substance satisfactory to the Mortgagee,

(v) the Mortgagee shall have received a certificate from the Lessee that no Event of Default exists as of the effective date of such assumption; and

(vi) the Mortgagee shall have received (A) from counsel for the Lessee (who may be an attorney in Lessee's legal department) a legal opinion, in form and substance as reasonably satisfactory to the Mortgagee: (w) with respect to the compliance of the assumption contemplated hereby with the terms hereof, (x) with respect to the due authorization, execution, delivery, validity, and enforceability of the instrument referred to in paragraph (i) of this Section 10.1.4(b), (y) with respect to the continued perfection of the first and prior Lien and security interest in the Aircraft for the benefit of the Holders of the Equipment Notes and the other Indenture Indemnitees (or the Lessee's substituted obligations) referred to in paragraph (ii) of this Section 10.1.4(b), and (z) with respect to the continued availability of the benefits of Section 1110 of the Bankruptcy Code to the Mortgagee for the benefit of the Holders with respect to the Aircraft after giving effect to such assumption, provided, that the opinion required by subclause (z) need only be given if immediately prior to such assumption the Owner Trustee should have been entitled to the benefits of Section 1110 of the Bankruptcy Code, (B) from counsel to the Mortgagee and special counsel in Oklahoma City, a legal opinion comparable to the respective opinions delivered on the Issuance Date or the Delivery Date, as the case may be, with such changes therein as may be appropriate in light of such assumption, and (C) in the case of each opinion described in clause (A) or (B) above, covering such additional matters as the Mortgagee shall reasonably request.

SECTION 14. CONCERNING OWNER TRUSTEE

It is understood and agreed that, except as otherwise expressly provided herein or in the Trust Agreement or the Trust Indenture, Owner Trustee is entering into this Agreement solely in its capacity as trustee as provided in the Trust Agreement and not in its individual capacity and in no case whatsoever will it be liable or accountable in its individual capacity for any of the statements, representations, warranties, agreements or obligations of Owner Trustee hereunder, or for any loss in respect thereof, as to all of which the parties agree to look solely to the Trust Estate; provided, that nothing in this
Section 14 shall be deemed to limit in scope or substance the personal liability of First Security (a) to Owner Participant as expressly set forth in the Trust Agreement, (b) in respect of the representations, warranties and agreements of First Security expressly made as such herein or in any other Operative Agreement to which it is a party, and (c) for the consequences of its own gross negligence, willful misconduct, and, in receiving, handling or remitting of funds only, its willful misconduct or simple negligence as a trustee.

LEASE AGREEMENT

LEASE AGREEMENT dated as of _______________ (this "Agreement" or "Lease"), between (a) FIRST SECURITY BANK, NATIONAL ASSOCIATION, a national banking association, not in its individual capacity, except as expressly provided herein, but solely as Owner Trustee (this and all other capitalized terms used but not defined herein shall have the respective meanings ascribed thereto in Section 1 below) ("Lessor" or "Owner Trustee"), and (b) ATLAS AIR, INC., a Delaware corporation ("Lessee").

RECITALS

A. Lessor and Lessee are parties to the Participation Agreement, pursuant to which, among other things, Lessor and Lessee have agreed to enter into this Agreement.

B. Pursuant to the Trust Agreement, Owner Participant has authorized Lessor to enter into this Agreement.

NOW, THEREFORE, for and in consideration of the premises and the mutual agreements contained herein and for other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. DEFINITIONS AND CONSTRUCTION

Capitalized terms used but not defined herein shall have the respective meanings set forth or incorporated by reference, and shall be construed and interpreted in the manner described, in Annex A.

SECTION 2. DELIVERY AND ACCEPTANCE

2.1 Delivery and Lease of Aircraft

Lessor hereby agrees (subject to the satisfaction or waiver of the conditions set forth in Section 5 of the Participation Agreement) to lease to Lessee for the Term and Lessee hereby agrees (subject to the satisfaction or waiver of the conditions set forth in Section 5 of the Participation Agreement) to lease from Lessor for the Term, the Aircraft, commencing


-2-

immediately upon acquisition of the Aircraft by Lessor pursuant to the Purchase Agreement Assignment.

2.2 Acceptance by Lessee

(a) By executing and delivering Lease Supplement No. 1, Lessee confirms to Lessor that Lessee has duly and irrevocably accepted delivery of the Aircraft for all purposes of this Agreement.

(b) Lessor has authorized one or more employees of Lessee, designated by Lessee in writing, as the authorized representative or representatives of Lessor to accept delivery of the Aircraft on behalf of Lessor pursuant to the Purchase Agreement Assignment and the Participation Agreement. Lessee hereby agrees that if delivery of the Aircraft shall be accepted by an employee or employees of Lessee pursuant to such authorization by Lessor, such acceptance of delivery by such employee or employees on behalf of Lessor shall, without further act, irrevocably constitute acceptance by Lessee of the Aircraft for all purposes of this Agreement.

SECTION 3. TERM AND RENT

3.1 Term

The Aircraft shall be leased hereunder for the Term, unless this Agreement or the leasing of the Aircraft is earlier terminated in accordance with any provision of this Agreement. Lessee shall have the option to renew the leasing of the Aircraft hereunder pursuant to, and subject to the terms and conditions of, Section 17.

3.2 Rent

3.2.1 Basic Rent; Adjustments to Basic Rent and Certain Other Amounts

(a) During the Base Lease Term, Lessee shall pay to Lessor, on each Payment Date, Basic Rent in the amount equal to the percentage of Lessor's Cost specified in Schedule 2 for such Payment Date, which shall be allocated to the Payment Period ending on such Payment Date, if designated as a payment in arrears, or allocated to the Payment Period commencing on such Payment Date, if designated as a payment in advance, in each case as specified in Schedule 2, as such amount may be adjusted pursuant to Section 3.2.1(b).


-3-

(b) Basic Rent, Stipulated Loss Values and Termination Values, the EBO Price and the EBO Date shall be subject to adjustment as follows:

(i) In the event that Transaction Expenses paid by Lessor pursuant to Section 9.2 of the Participation Agreement are determined to be other than [ ]% of Lessor's Cost, then in each case the Basic Rent percentages set forth in Schedule 2, the Stipulated Loss Value percentages set forth in Schedule 3, the Termination Value percentages set forth in Schedule 4 and the EBO Price and the EBO Date set forth in Schedule 1 shall be recalculated (upwards or downwards) by the Owner Participant, on or prior to the 120th day after the Delivery Date using the same methods and assumptions used to calculate the original Basic Rent, Stipulated Loss Value and Termination Value percentages and the EBO Price and the EBO Date in order to (1) maintain the Owner Participant's Net Economic Return and (2) minimize the Net Present Value of Rents and the EBO Price to Lessee to the extent possible consistent with clause (1) hereof.

(ii) In the event of a refinancing as contemplated by Section 11 of the Participation Agreement, then the Basic Rent percentages set forth in Schedule 2, the Stipulated Loss Value percentages set forth in Schedule 3, the Termination Value percentages set forth in Schedule 4 and the EBO Price and the EBO Date set forth in Schedule 1 shall be recalculated (upwards or downwards) by the Owner Participant using the same methods and assumptions used to calculate the original Basic Rent, Stipulated Loss Value and Termination Value percentages and the EBO Price and the EBO Date to (1) maintain the Owner Participant's Net Economic Return and (2) to the extent possible consistent with clause
(1) hereof, minimize the Net Present Value of Rents and the EBO Price to Lessee.

(iii) In the event that Lessee is required to indemnify the Owner Participant under the Tax Indemnity Agreement, then (A) in the event that Lessee agrees to satisfy such indemnity obligation pursuant to Section __ of the Tax Indemnity Agreement, the Basic Rent percentages set forth in Schedule 2, and (B) in any case, the Stipulated Loss Value percentages set forth in Schedule 3 and the Termination Value percentages set forth in Schedule 4 shall be recalculated (upwards or downwards) by Owner Participant, using the same methods and assumptions (except to the extent such assumptions shall be varied to take


-4-

into account the Tax Loss [or Foreign Tax Credit Loss] (as each such term is defined in the Tax Indemnity Agreement) that is the subject of such indemnification and any prior or contemporaneous Tax Loss [or Foreign Tax Credit Loss]) used to calculate the Basic Rent percentages, the Stipulated Loss Value percentages and the Termination Value percentages in order to (1) maintain the Owner Participant's Net Economic Return and (2) to the extent possible consistent with clause
(1) hereof, minimize the Net Present Value of Rents and the EBO Price to Lessee.

(c) All adjustments pursuant to Section 3.2.1(b) shall be made as promptly as practicable after either Owner Participant or Lessee gives notice to the other that an event has occurred that requires an adjustment. Owner Participant and Lessee shall give prompt notice to the other of any event requiring an adjustment. Any recalculation of the percentages of Basic Rent, the EBO Price and the EBO Date (which may change only at the election of Lessee), Stipulated Loss Value and Termination Value shall be prepared by Owner Participant, subject to verification by Lessee in accordance with Section 3.2.1(d), using the same methodology and assumptions used by Owner Participant in determining the percentages of Basic Rent, Stipulated Loss Value and Termination Value and the EBO Price and the EBO Date as of the Delivery Date, except as such methodologies and assumptions have been modified to reflect the events giving rise to adjustments hereunder. Promptly after an adjustment is made hereunder, Owner Participant shall deliver to Lessee a description of such adjustment, setting forth in reasonable detail the calculation thereof. All adjustments shall (i) be made so as to avoid characterization of the Lease as a "disqualified leaseback or long-term agreement" within the meaning of Section 467 of the Code and/or regulations thereunder (or any successor or relevant code provision or regulations) and (ii) be in compliance with the requirements of Sections 4.02(5), 4.07(l) and, on a prospective basis, 4.08(1) of Revenue Procedure 75-28 (or any successor or relevant procedure), except to the extent that on the Delivery Date the Lease constituted a "disqualified leaseback or long-term agreement" or was not in compliance with the revenue procedure referred to in clause (ii). All adjustments required pursuant to Section 3.2.1(b) shall be set forth in a Lease Supplement or in an amendment to this Lease, and , promptly after execution thereof by Lessor and Lessee, Lessee shall give a copy thereof to Mortgagee.

(d) If Lessee believes that any calculations by Owner Participant pursuant to Section 3.2.1(c) are in error,


-5-

and if, after consultation, Lessee and Owner Participant are unable to agree on an adjustment, then Babcock & Brown Inc. or any other nationally recognized certified public accounting or lease advisory firm selected by Lessee and reasonably satisfactory to Owner Participant shall verify such calculations. Owner Participant will make available to such firm, but not, in any circumstances, to Lessee or any representative of Lessee, the methodology and assumptions referred to in Section 3.2.1(b) and any modifications thereto made to reflect the events giving rise to adjustments hereunder (subject to the execution by such firm of a confidentiality agreement, reasonably acceptable to Owner Participant, prohibiting disclosure of such methodology and assumptions to any third party). The determination by such firm shall be final. Lessee will pay the reasonable costs and expenses of such further verification by such firm, provided that if such verification results in a decrease in Basic Rent which decreases the remaining Net Present Value of Rents and/or the EBO Price by $10,000 or more from the remaining Net Present Value of Rents and/or the EBO Price as recalculated by the Owner Participant, then the Owner Participant will pay such costs and expenses.

(e) Notwithstanding anything to the contrary in any Operative Agreement, the amount of the payment of Basic Rent due and payable on each Payment Date shall be at least sufficient to pay in full, as of such Payment Date (assuming timely payment of the Equipment Notes prior to such Payment Date), the aggregate principal amount of scheduled installments due on the Equipment Notes outstanding on such Payment Date, together with the accrued and unpaid interest thereon, due on such Payment Date in respect of the Equipment Notes; provided, however, that no installment of Basic Rent shall be increased to the extent such increase would be based upon (i) any attachment or diversion of Basic Rent on account of Lessor Liens attributable to Lessor or Owner Participant, (ii) any modification of the payment terms of the Equipment Notes, other than as required or permitted by any Operative Agreement (including, without limitation, as permitted upon the occurrence of a Lease Event of Default) or (iii) the acceleration of any Equipment Note or Equipment Notes due solely to the occurrence of an Event of Default that does not constitute a Lease Event of Default.

3.2.2 Supplemental Rent

Lessee shall pay to Lessor, or to whosoever shall be entitled thereto, any and all Supplemental Rent when and as the same shall become due and owing. Lessee will also pay to Lessor, or to whosoever shall be entitled thereto as Supplemental


-6-

Rent, to the extent permitted by applicable Law, interest at the Payment Due Rate on any part of any amount of Rent (including, without limitation, Supplemental Rent) not paid by 12:30 p.m., New York time, on the date when due (so long as, in the case of any person not a party to the Participation Agreement, Lessee had received timely notice of the account to which such payment was required to be made), for the period from and including the date on which the same was due to, but excluding, the date of payment in full.

3.3 Payments

(a) Payments of Rent by Lessee shall be paid by wire transfer of immediately available Dollars, not later than 12 noon, New York time, on the date when due, to the account of Lessor specified in Schedule 1 to the Participation Agreement or to such other account in the United States as directed by Lessor to Lessee in writing at least 10 Business Days prior to the date such payment of Rent is due or, in the case of any payment of Supplemental Rent expressly payable to a person other than Lessor, to the person that shall be entitled thereto to such account in the United States as such person may specify from time to time to Lessee at least 10 Business Days prior to the date such payment of Rent is due.

(b) Except as otherwise expressly provided herein, whenever any payment of Rent shall be due on a day that is not a Business Day, such payment shall be made on the next day that is a Business Day, and, if such payment is made on such next Business Day, no interest shall accrue on the amount of such payment during such extension.

(c) So long as Lessee has not received written notice from the Mortgagee that the Lien of the Trust Indenture has been discharged, and notwithstanding Section 3.3(a), Lessor hereby directs, and Lessee agrees, that all payments of Rent and all other amounts payable by Lessee hereunder, other than Excluded Payments, shall be paid directly to Mortgagee on behalf of Lessor by wire transfer of immediately available Dollars to the account of Mortgagee specified in Schedule 1 to the Participation Agreement, or to such other account in the United States as Mortgagee may specify by written notice to Lessor and Lessee at least 10 Business Days prior to the date such payment of Rent is due.

(d) Excluded Payments shall be paid by wire transfer to the person entitled thereto pursuant to the Operative Agreements of immediately available Dollars to the account of such


-7-

person specified in the Participation Agreement or, if not so specified, to such account in the United States as may be specified by such person by written notice to Lessor and Lessee from time to time at least 10 Business Days prior to the date such payment is required to be made.

(e) All computations of interest under this Agreement shall be made on the basis of a year of 360 days comprised of twelve 30-day months.

4.2 Certain Agreements of Lessor

Unless a Lease Event of Default shall have occurred and be continuing, Lessor agrees to make available to Lessee such rights as Lessor may have under any warranty with respect to the Aircraft made, or made available, by Airframe Manufacturer or Engine Manufacturer or any of their respective subcontractors or suppliers, as the case may be, pursuant to and in accordance with the terms of the Purchase Agreement Assignment.

4.3 Quiet Enjoyment

So long as no Lease Event of Default shall have occurred and be continuing, Lessor shall not take or cause to be taken or permit any Person lawfully claiming by or through it to take any action to interfere with Lessee's (or any Permitted Sublessee's) rights hereunder to continued possession, use and operation of, and quiet enjoyment of the Aircraft, the Airframe, any Engine or any Part and other rights with respect to the Aircraft hereunder during the Term.

4.4 Investment of Funds Held as Security

4.4.1 Investment

Any moneys held by Lessor as security for Lessee's obligations under the Operative Agreements, shall, until paid to Lessee as provided herein or applied as provided herein, be invested by Lessor from time to time as directed in writing by Lessee (or, if Lessee fails to so direct, as directed by Lessor in its sole discretion) and at the expense and risk of Lessee in Cash Equivalents so long as such Cash Equivalents specified by Lessee or Lessor, as the case may be, can be acquired by Lessor using its best efforts; provided, that so long as the Lien of the Trust Indenture shall not have been discharged, such moneys shall be invested and held by Mortgagee, as assignee of Lessor, in accordance with this Lease and upon discharge of such Lien, Mortgagee shall pay any such money held by it to Lessor to be held and invested in accordance with this Section.

held and applied hereunder. Lessee will promptly pay to Lessor, on demand, the amount of any loss realized as the result of any such investment (together with any fees, commissions and other reasonable expenses, if any, incurred in connection with such investment), such amount so paid to be held and applied by Lessor as contemplated in Section 4.4.1 above.

4.4.3 Limitation of Liability

All investments under this Section 4.4 shall be at the expense and risk of Lessee, and Lessor and Mortgagee shall not be liable for any loss resulting from any investment made under this Section 4.4 other than by reason of its willful misconduct or gross negligence. Any such investment may be sold (without regard to its maturity) by Lessor, or by Mortgagee as assignee of Lessor, without instructions whenever such sale is necessary to make a distribution required by this Lease.

4.5 Title Transfers by Lessor

If Lessor shall be required to transfer title to the Aircraft, Airframe or any Engine to Lessee or any other person pursuant to this Lease, then (a) Lessor shall (1) transfer to Lessee or such other person, as the case may be, all of Lessor's right, title and interest in and to the Aircraft, Airframe or such Engine, as the case may be, free and clear of all Lessor Liens attributable to Lessor or Owner Participant, (2) so long as the Lien of the Trust Indenture has not been discharged, comply with the terms of the Trust Indenture relating to the release of the Aircraft, Airframe or such Engine, (3) assign to Lessee or such other person, as the case may be, if and to the extent permitted under the Purchase Agreement, all warranties of Airframe Manufacturer and Engine Manufacturer with respect to the Aircraft, Airframe or such Engine, and (4) assign to Lessee or such other person, as the case may be, if and to the extent permitted, all claims, if any, for damage to the Aircraft, Airframe or such Engine, in each case free of Lessor Liens attributable to Lessor or Owner Participant, and without recourse or warranty of any kind whatsoever (except as to the transfer described in clause (1) above and as to the absence of such Lessor Liens, as aforesaid), and (b) Lessor shall promptly deliver to Lessee or such other person, as the case may be, a bill of sale and agreements of assignment, evidencing such transfer and assignment, and such other instruments of transfer, all in form and substance reasonably satisfactory to Lessee (or such other person, as the case may be), as Lessee (or such other person, as the case may be) may reasonably request.

Lessor hereby agrees for the benefit of each lessor, conditional seller, indenture trustee or secured party of any engine leased to, or purchased by, Lessee or any Permitted Sublessee subject to a lease, conditional sale, trust indenture or other security agreement that Lessor, its successors and assigns will not acquire or claim, as against such lessor, conditional seller, indenture trustee or secured party, any right, title or interest in any engine as the result of such engine being installed on the Airframe at any time while such engine is subject to such lease, conditional sale, trust indenture or other security agreement and owned by such lessor or conditional seller or subject to a trust indenture or security interest in favor of such indenture trustee or secured party.

4.7 Lease for U.S. Federal Income Tax Law Purposes; Section 1110 of Bankruptcy Code

(a) Lessee and Lessor agree that this Lease is, and shall be treated as, a lease for U.S. federal income tax purposes of the Aircraft, Airframe, Engines and Parts.

(b) It is the intention of each of Lessee and Lessor that Lessor (and Mortgagee as assignee of Lessor under the Trust Indenture) shall be entitled to the benefits of Section 1110 with respect to the right to take possession of the Aircraft, Airframe, Engines and Parts as provided in this Lease.

SECTION 5. RETURN OF AIRCRAFT

5.1 Compliance with Annex B

Lessee shall comply with each of the provisions of Annex B hereto, which provisions are hereby incorporated by this reference as if set forth in full herein.

5.2 Storage and Related Matters

If Lessor gives written notice to Lessee not less than 60 days nor more than 120 days prior to the end of the Term requesting outdoor parking of the Aircraft upon its return hereunder, Lessee will assist Lessor in arranging outdoor parking facilities for the Aircraft for a period up to 30 days, commencing on the date of such return, and upon request of Lessor to Lessee made at least 10 days prior to the end of such initial 30 day period, for an additional 30 day period commencing


-11-

upon expiration of such initial period, at such outdoor parking facility in the 48 contiguous states of the United States as Lessee may select. Lessee shall, at Lessor's written request, maintain insurance (if available) for the Aircraft during such outdoor parking period, provided that Lessor shall reimburse Lessee for Lessee's out-of-pocket cost of providing such insurance. Such outdoor parking shall be at Lessor's risk, and Lessor shall pay all applicable outdoor parking fees; provided that Lessee's obligation to assist Lessor in arranging parking shall be subject to Lessor entering into an agreement prior to the commencement of the outdoor parking period with the outdoor parking facility providing, among other things, that Lessor shall bear all maintenance charges (other than maintenance required as a direct result of Lessee's failure to comply with the provisions of Annex B) and other costs incurred.

5.3 Return of Other Engines

In the event that any Engine owned by Lessor shall not be installed on the Airframe at the time of return hereunder, Lessee shall be required to return the Airframe hereunder with a Replacement Engine meeting the requirements of, and in accordance with, Section 10 hereof and Annex B hereto. Thereupon, Lessor will transfer to Lessee the Engine constituting part of such Aircraft but not installed on such Airframe at the time of the return of the Airframe.

5.4 Fuel

Upon the return of the Airframe upon any termination of this Lease, Lessor shall pay Lessee, as compensation for any fuel or oil contained in the fuel or oil tanks of such Airframe, the value of such fuel or oil at the price paid by Lessee for such fuel or oil, provided that if the Aircraft is being returned in connection with the exercise of remedies pursuant to Section 15, Lessor shall have no obligation to make such payment to Lessee until Lessor shall have been paid all amounts due to it pursuant to Section 15.

SECTION 6. LIENS

Lessee shall not, directly or indirectly, create, incur, assume or suffer to exist any Lien on or with respect to the Aircraft, the Airframe, any Engine or any Part, title to any of the foregoing or any interest of Lessee therein, or the Lessee's rights in and to this Lease or any Permitted Sublease,

(d) Liens for Taxes of Lessee or any Permitted Sublessee (and their respective U.S. federal tax law consolidated groups), or Liens for Taxes of any Tax Indemnitee (and its U.S. federal tax law consolidated group) for which Lessee is obligated to indemnify such Tax Indemnitee under any of the Lessee Operative Agreements, in any such case either not yet due or being contested in good faith by appropriate proceedings so long as such Liens and such proceedings do not involve any material risk of the sale, forfeiture or loss of the Aircraft, the Airframe, any Engine or the interest of any Participant therein or impair the lien of the Trust Indenture; (e) materialmen's, mechanics', workers', repairers', employees' or other like Liens arising in the ordinary course of business for amounts the payment of which is either not yet delinquent for more than 60 days or is being contested in good faith by appropriate proceedings, so long as such Liens and such proceedings do not involve any material risk of the sale, forfeiture or loss of the Aircraft, the Airframe, any Engine or the interest of any Participant therein or impair the lien of the Trust Indenture;
(f) Liens arising out of any judgment or award against Lessee (or against any Permitted Sublessee), so long as such judgment shall, within 60 days after the entry thereof, have been discharged or vacated, or execution thereof stayed pending appeal or shall have been discharged, vacated or reversed within 60 days after the expiration of such stay, and so long as during any such 60-day period there is not, or any such judgment or award does not involve, any material risk of the sale, forfeiture or loss of the Aircraft, the Airframe, any Engine or the interest of any Participant therein or impair the lien of the Trust Indenture, and (g) any other Lien with respect to which Lessee (or any Permitted Sublessee) shall have provided a bond, cash collateral or other security adequate in the reasonable opinion of Lessor. Lessee shall promptly take (or cause to be taken) such action as may be necessary duly to discharge (by bonding or otherwise) any Lien not excepted above if the same shall at any time arise in respect of the Aircraft, the Airframe, any Engine or any Part during the Term.

SECTION 7. REGISTRATION, OPERATION, POSSESSION, SUBLEASING AND RECORDS

7.1 Registration and Operation

7.1.1 Registration and Recordation

Subject to the compliance by Lessor and Owner Participant with their respective obligations under Section 13 of the Participation Agreement, Lessee shall cause the Aircraft to be, and at all times during the Term to remain, duly registered with the FAA under the Act or with such other country of registry as shall be permitted under Section 7.1.2 below, in the name of Lessor as owner and lessor (except to the extent that such registration under the Act cannot be effected with the FAA because of Lessor's or Owner Participant's failure to comply with the citizenship requirements for registration of the Aircraft under the Act). Lessor shall execute and deliver all such documents as Lessee (or any Permitted Sublessee) may reasonably request for the purpose of effecting and continuing such registration. Unless Mortgagee has given Lessee notice that the Trust Indenture has been discharged, Lessee shall also cause the Trust Indenture to be duly recorded and at all times maintained of record as a first-priority perfected mortgage (subject to Permitted Liens) on the Aircraft, the Airframe and each of the Engines (except to the extent such perfection or priority cannot be maintained solely as a result of the failure by Lessor or Mortgagee to execute and deliver any necessary documents).

7.1.2 Reregistration

So long as no Lease Event of Default shall have occurred and be continuing, Lessee may, by written notice to Lessor, request to change the country of registration of the Aircraft. Any such change in registration shall be effected only in compliance with, and subject to all of the conditions set forth in, Section 7.6.11 of the Participation Agreement.

7.1.3 Markings

If permitted by applicable Law, on or reasonably promptly after the Delivery Date, Lessee will cause to be affixed to, and maintained in, the cockpit of the Airframe and on each Engine, in each case, in a clearly visible location (it being understood that the location of such placards, as identified to the Owner Participant prior to the Delivery Date, shall be deemed to be in compliance with this requirement), a placard


-14-

of a reasonable size and shape bearing the legend, in English, set forth in Schedule 6. Such placards may be removed temporarily, if necessary, in the course of maintenance of the Airframe or Engines. If any such placard is destroyed or becomes illegible, Lessee shall promptly replace it with a placard complying with the requirements of this Section 7.1.3.

7.1.4 Compliance With Laws

Lessee shall not, and shall not allow any other person to, operate, use, maintain, service, repair or overhaul the Aircraft (a) in violation of any Law binding on or applicable to the Aircraft, the Airframe or any Engine, or (b) in violation of any airworthiness certificate, license or registration of any Government Entity relating to the Aircraft, the Airframe or any Engine, except (1) immaterial or non-recurring violations with respect to which corrective measures are taken promptly by Lessee or a Permitted Sublessee, as the case may be, upon discovery thereof, and (2) to the extent Lessee or any Permitted Sublessee is contesting the validity or application of any such Law or requirement relating to any such certificate, license or registration in good faith in any reasonable manner which does not involve any material risk of the sale, forfeiture or loss of the Aircraft, the Airframe, any Engine or the interest of any Participant therein, any material risk of criminal liability or of material risk of civil penalty against Lessor, Mortgagee or any Participant or impair the lien of the Trust Indenture.

7.1.5 Operation

Lessee agrees not to operate, use or locate the Aircraft, the Airframe or any Engine, or allow the Aircraft, the Airframe or any Engine to be operated, used or located (a) in any area excluded from coverage by any insurance required by the terms of Section 11, except in the case of a requisition by or transfer to the U.S. Government where Lessee obtains an indemnity in lieu of such insurance from the U.S. Government, or insurance from the U.S. Government, covering such area, in accordance with Section 11.3 or (b) in any recognized area of hostilities unless fully covered in accordance with Annex D by war-risk insurance as required by the terms of Section 11 (including, without limitation, Section 11.3), unless in any case referred to in this
Section 7.1.5 the Aircraft is only temporarily operated, used or located in such area as a result of an emergency, equipment malfunction, navigational error, hijacking, weather condition or other similar unforeseen circumstances,


-15-

so long as Lessee diligently and in good faith proceeds to remove the Aircraft from such area.

7.2 Possession

Lessee will not, without the prior written consent of Lessor, sublease or otherwise in any manner deliver, transfer or relinquish possession of the Aircraft, the Airframe or any Engine or install any Engine, or permit any Engine to be installed, on any airframe other than the Airframe; provided, however, subject to the provisions of Section 7.3, Lessee may, without such prior written consent:

7.2.1 Interchange and Pooling

Subject or permit any Permitted Sublessee to subject any Engine to normal interchange agreements or pooling agreements or arrangements, in each case customary in the commercial air cargo industry and entered into by Lessee or such Permitted Sublessee, as the case may be, in the ordinary course of business; provided, however, that if Lessor's title to any such Engine is divested under any such agreement or arrangement, then such Engine shall be deemed to have suffered an Event of Loss as of the date of such divestiture, with the effect that Lessee shall be required to replace such Engine with a Replacement Engine meeting the requirements of, and in accordance with,
Section 10.

7.2.2 Testing and Service

Deliver or permit any Permitted Sublessee to deliver possession of the Aircraft, Airframe, any Engine or any Part (i) to the manufacturer thereof or to any third-party maintenance provider, for testing, service, repair, maintenance or overhaul work on the Aircraft, Airframe, any Engine or any Part, or, to the extent required or permitted by the terms of Annex C, for alterations or modifications in or additions to the Aircraft, Airframe or any Engine or (ii) to any Person for the purpose of transport to a Person referred to in the preceding clause (i).

7.2.3 Transfer to U.S. Government

Transfer or permit any Permitted Sublessee to transfer possession of the Aircraft, Airframe or any Engine to the U.S. Government, in which event Lessee shall promptly notify Lessor and Mortgagee in writing of any such transfer of possession and, in the case of any transfer pursuant to CRAF, in such


-16-

notification shall identify by name, address and telephone numbers the Contracting Office Representative or Representatives for the Military Airlift Command of the United States Air Force to whom notices must be given and to whom requests or claims must be made to the extent applicable under CRAF.

7.2.4 Installation of Engines on Owned Aircraft

Install or permit any Permitted Sublessee to install an Engine on an airframe owned by Lessee or such Permitted Sublessee, as the case may be, free and clear of all Liens, except (a) Permitted Liens and those that do not apply to the Engines and (b) the rights of third parties under normal interchange or pooling agreements and arrangements of the type that would be permitted under Section 7.2.1.

7.2.5 Installation of Engines on Other Airframes

Install or permit any Permitted Sublessee to install an Engine on an airframe leased to Lessee or such Permitted Sublessee, or purchased by Lessee or such Permitted Sublessee subject to a mortgage, security agreement, conditional sale or other secured financing arrangement, but only if (a) such airframe is free and clear of all Liens, except (i) the rights of the parties to such lease, or any such secured financing arrangement, covering such airframe and (ii) Liens of the type permitted by clauses (a) and (b) of Section 7.2.4 and
(b) Lessee or Permitted Sublessee, as the case may be, shall have received from the lessor, mortgagee, secured party or conditional seller, in respect of such airframe, a written agreement (which may be a copy of the lease, mortgage, security agreement, conditional sale or other agreement covering such airframe), whereby such Person agrees that it will not acquire or claim any right, title or interest in, or Lien on, such Engine by reason of such Engine being installed on such airframe at any time while such Engine is subject to this Lease or is owned by Lessor.

7.2.6 Installations of Engines on Financed Aircraft

Install or permit any Permitted Sublessee to install an Engine on an airframe owned by Lessee or such Permitted Sublessee, leased to Lessee or such Permitted Sublessee, or purchased by Lessee or such Permitted Sublessee subject to a conditional sale or other security agreement under circumstances where neither Section 7.2.4 or 7.2.5 is applicable; provided, however, that any such installation shall be deemed an Event of Loss with respect to such Engine, and Lessee shall comply with


-17-

Section 10.2 hereof in respect thereof. Until Section 10.2 has been fully complied with, Lessor's interest in any such Engine shall continue in full force and effect.

7.2.7 Subleasing

With respect to the Aircraft, Airframe or any Engine, so long as no Lease Event of Default shall have occurred and is continuing, enter into a sublease with any Permitted Air Carrier, but only if:

(a) Lessee shall provide written notice to Lessor and Mortgagee (such notice in the event of a sublease to a U.S. Air Carrier to be given promptly after entering into any such sublease or, in the case of a sublease to any other Permitted Air Carrier, 10 days in advance of entering into such sublease);

(b) At the time that Lessee enters into such sublease, such Permitted Air Carrier shall not be subject to any bankruptcy, insolvency, liquidation, reorganization, dissolution or similar proceeding, and shall not have substantially all of its property in the possession of any liquidator, trustee, receiver or similar person;

(c) Any such sublease (i) shall not extend beyond the expiration of the Base Lease Term or any Renewal Lease Term then in effect unless Lessee shall have irrevocably committed to purchase the Aircraft, (ii) shall include provisions for the maintenance, operation, possession, inspection and insurance of the Aircraft that are the same in all material respects as the applicable provisions of this Lease and
(iii) shall be expressly subject and subordinate to all the terms of this Agreement and to the rights, powers and remedies of Lessor hereunder, including, without limitation, Lessor's rights under Section 15 to repossess the Aircraft, Airframe and Engines and to terminate such sublease upon the occurrence of a Lease Event of Default;

(d) In connection with a sublease to a Permitted Foreign Air Carrier or a Permitted Foreign Manufacturer, (1) the United States maintains diplomatic relations with the country of domicile of such Permitted Foreign Air Carrier or Permitted Foreign Manufacturer (or, in the case of Taiwan, diplomatic relations at least as good as those in effect on the Delivery Date) and (2) Lessee shall have furnished Lessor, Owner Participant and Mortgagee a favorable


-18-

opinion of counsel, reasonably satisfactory to Lessor and Owner Participant, in the country of domicile of such Permitted Foreign Air Carrier or Permitted Foreign Manufacturer, that (i) the terms of such sublease are the legal, valid and binding obligations of the parties thereto enforceable under the laws of such jurisdiction, (ii) it is not necessary for Owner Participant, Lessor or Mortgagee to register or qualify to do business in such jurisdiction, if not already so registered or qualified, as a result, in whole or in part, of the proposed sublease, (iii) Lessor's title to, and Mortgagee's Lien in respect of, the Aircraft, Airframe and Engines will be recognized in such jurisdiction, (iv) the Laws of such jurisdiction of domicile require fair compensation by the government of such jurisdiction, payable in a currency freely convertible into Dollars, for the loss of title to the Aircraft, Airframe or Engines in the event of the requisition by such government of such title (unless Lessee shall provide insurance in the amounts required with respect to hull insurance under Section 11 covering the requisition of title to the Aircraft, Airframe or Engines by the government of such jurisdiction so long as the Aircraft, Airframe or Engines are subject to such sublease) and (v) the agreement of such Permitted Foreign Air Carrier or Permitted Foreign Manufacturer that its rights under the sublease are subject and subordinate to all the terms of this Lease is enforceable against such Permitted Foreign Air Carrier or Permitted Foreign Manufacturer under applicable law;

(e) Lessee shall furnish to Lessor, Mortgagee and Owner Participant evidence reasonably satisfactory to Lessor that the insurance required by Section 11 remains in effect;

(f) All necessary documents shall have been duly filed, registered or recorded in such public offices as may be required fully to preserve the title of Lessor, and the first priority security interest (subject to Permitted Liens) of Mortgagee, in the Aircraft, Airframe and Engines;

(g) Lessee shall reimburse Lessor, Mortgagee and Owner Participant for all of their reasonable out-of-pocket fees and expenses, including, without limitation, reasonable fees and disbursements of counsel, incurred by Lessor, Mortgagee and Owner Participant in connection with any such sublease;


-19-

(h) For all purposes of this Section 7.2.7, the term "sublease" shall be deemed to include interchange agreements with respect to the Aircraft or Airframe; and

(i) No such sublease shall be made to a Permitted Foreign Air Carrier or a Permitted Foreign Manufacturer prior to the close of the Tax Attribute Period, unless Lessee prepays on a lump-sum basis any liability due under the Tax Indemnity Agreement as a result of such sublease based upon the assumption that such sublease were to continue for the remainder of the term of such sublease; provided, however, that such sublease shall not be restricted under this paragraph (i) if it would not have the effect of lengthening the "recovery period" (as defined in Section 168 of the Code) then applicable to the Aircraft.

7.3 Certain Limitations on Subleasing or Other Relinquishment of Possession

Notwithstanding anything to the contrary in Section 7.2:

(a) The rights of any person that receives possession of the Aircraft in accordance with Section 7.2 shall be subject and subordinate to all the terms of this Lease, and to Lessor's rights, powers and remedies hereunder, including, without limitation (i) Lessor's right to repossess the Aircraft pursuant to Section 15, (ii) Lessor's right to terminate and avoid such sublease, delivery, transfer or relinquishment of possession upon the occurrence of a Lease Event of Default and (iii) the right to require such person to forthwith deliver the Aircraft, the Airframe and Engines subject to such transfer upon the occurrence of a Lease Event of Default;

(b) Lessee shall remain primarily liable hereunder for the performance of all the terms of this Lease to the same extent as if such transfer had not occurred, and no transfer of possession of the Aircraft, the Airframe, any Engine or any Part shall in any way discharge or diminish any of Lessee's obligations to Lessor hereunder or under any Operative Agreement;

(c) Lessee shall ensure that no sublease, delivery, transfer or relinquishment permitted under Section 7.2 shall affect the United States registration of the Aircraft, unless also made in accordance with the provisions of Section 7.1.2;


-20-

(d) Any event that constitutes or would, with the passage of time, constitute an Event of Loss under paragraph (c), (d), or (e) of the definition of such term (as set forth in Annex A) shall not be deemed to violate the provisions of Section 7.2; and

(e) Any Wet Lease or ACMI Contract shall not constitute a delivery, transfer or relinquishment of possession for purposes of
Section 7.2 and shall not be prohibited by the terms hereof, but shall be subject and subordinate to the terms of this Lease. Neither a Wet Lease nor an ACMI contract shall be deemed to be a "sublease", and the counterparty of a Wet Lease or an ACMI Contract shall not be deemed to be a sublessee for any purposes under this Lease. Any contract that is part of the United States Civil Reserve Air Fleet Program shall not be deemed to be a sublease for any purposes under this Lease.

-21-

copy of Lessee's report on Form 10-Q for such fiscal quarter (excluding exhibits) will satisfy this paragraph (a).

(b) Within 120 days after the end of each fiscal year of Lessee, a consolidated balance sheet of Lessee as of the end of such fiscal year and related statements of income and cash flows of Lessee for such fiscal year, in comparative form with the preceding fiscal year, prepared in accordance with GAAP, together with a report of Lessee's independent certified public accountants with respect to their audit of such financial statements; provided that so long as Lessee is subject to the reporting requirements of the Securities Exchange Act of 1934, a copy of Lessee's report on Form 10-K for such fiscal year (excluding exhibits) will satisfy this paragraph (b).

8.2.2 Annual Certificate

Within 120 days after the close of each fiscal year of Lessee, Lessee shall deliver to Lessor and Mortgagee an Officer's Certificate of Lessee to the effect that such officer is familiar with or has reviewed or caused to be reviewed the relevant terms of this Lease and the other Lessee Operative Agreements and that such officer does not have knowledge of the existence as of the date of such certificate of any Lease Event of Default.

-22-

to the filing of such information directly by Lessee or such Permitted Sublessee in lieu of filing by Owner Participant or Lessor, and if any such waiver or consent is evidenced to the reasonable satisfaction of Owner Participant or Lessor, as the case may be, then Lessee shall not be required to furnish such information to Owner Participant or Lessor.

8.2.4 Other

Lessee shall furnish annually any such opinions as may be required pursuant to Section 7.1.3(d) of the Participation Agreement.

SECTION 9. VOLUNTARY TERMINATION UPON OBSOLESCENCE

9.1 Right of Termination

(a) Lessee shall have the right at its option to terminate this Lease during the Base Lease Term, effective only on a Termination Date occurring on or after the fifth anniversary of the Delivery Date, if:

-23-

In addition, Lessee shall have no obligation to Lessor or any other party to accept any bid solicited pursuant to this Section 9.2.1 that Lessee, in good faith, believes is unlikely to result in the consummation of the sale of the Aircraft in accordance with the terms hereof.


-24-

(c) For purposes of Section 10.1.2, an Event of Loss with respect to the Airframe shall be deemed to constitute an Event of Loss with respect to the Aircraft. For purposes of Section 10.1.3, any Engine not actually suffering an Event of Loss shall not be required to be replaced.

(i) on the earlier of (x) the first Business Day following the 180th day after the date of the occurrence of such Event of Loss, and (y) the Business Day specified by Lessee as the payment date in an irrevocable notice delivered by Lessee to the applicable Lessor and Mortgagee not less than 20 days prior to such payment date, Lessee shall pay to Lessor an amount equal to the Stipulated Loss Value of the Aircraft as of the Loss Payment Date plus:

If Lessee makes such election, but for any reason fails or is unable to effect such replacement within such time period and in compliance with the requirements set forth in Section 10.3, then Lessee shall be deemed to have initially made the election set forth in Section 10.1.2 with the effect that Lessee shall immediately pay, in the manner and in funds of the type specified in Section 3.3, the amounts required under, and in accordance with, Section 10.1.2.

Any such Replacement Engine shall meet the requirements of, and be conveyed by Lessee to Lessor in accordance with, Section 10.2 (other than the notice requirement set forth in Section 10.2.1).

10.2.3 Engine Exchange

Upon not less than five Business Days' prior written notice to Lessor, Lessee may replace any Engine leased hereunder with another engine (the "Exchanged Engine") meeting the requirements of Section 10.2.2.

10.3 Conditions to any Replacement

10.3.1 Documents

Prior to or at the time of conveyance of title to any Replacement Airframe or Replacement Engine to Lessor, Lessee shall take each of the following actions:

(a) furnish Lessor with a full warranty bill of sale duly conveying to Lessor such Replacement Airframe or Replacement Engine, in form and substance reasonably satisfactory


-31-

to Lessor and cause such Replacement Airframe to be duly registered in the name of Lessor pursuant to the Act;

(b) cause (i) a Lease Supplement subjecting such Replacement Airframe or Replacement Engine to this Lease, duly executed by Lessee, to be delivered to Lessor for execution and, upon such execution, to be filed for recordation with the FAA pursuant to the Act, (ii) a Trust Indenture Supplement, subjecting such Replacement Airframe or Replacement Engine to the Trust Indenture, to be delivered to Lessor for execution and, upon execution, to be filed for recordation with the FAA pursuant to the Act and (iii) such Financing Statements and other filings, as Lessor or Mortgagee may reasonably request, duly executed by Lessee and, to the extent applicable, Lessor and Mortgagee (and Lessor and Mortgagee shall execute and deliver the same), to be filed in such locations as any such party may reasonably request;

(c) furnish such evidence of compliance with the insurance provisions of Section 11 with respect to such Replacement Airframe or Replacement Engine as Lessor may reasonably request;

(d) furnish an opinion or opinions of Lessee's counsel (which may be Lessee's legal department) reasonably satisfactory to Lessor and addressed to Lessor and Mortgagee to the effect that (i) such full warranty bill of sale referred to in Section 10.3.1(a) constitutes an effective instrument for the conveyance of title to the Replacement Airframe or Replacement Engine and (ii) in the case of a Replacement Airframe, Lessor and Mortgagee, as assignee of Lessor, will be entitled to the benefits of Section 1110 with respect to the Replacement Airframe, provided that such opinion referred to in this clause (ii) need not be delivered to the extent that immediately prior to such replacement the benefits of Section 1110 were not, solely by reason of a change in law or court interpretation thereof, available to Lessor or Mortgagee, as assignee of Lessor;

(e) furnish an opinion of Lessee's aviation law counsel reasonably satisfactory to Lessor and addressed to Lessor and Mortgagee as to the due registration of any such Replacement Airframe and the due filing for recordation of each Lease Supplement and Trust Indenture Supplement with respect to such Replacement Airframe or Replacement Engine under the Act;


-32-

(f) with respect to any Replacement Airframe, furnish an opinion of tax counsel, selected by Owner Participant and reasonably satisfactory to Lessee, as to the federal income tax consequences (without any requirement as to the nature of such Federal income tax consequences) to Lessor and Owner Participant of any such replacement;

(g) with respect to the replacement of the Airframe, and any Engine installed thereon at the time of the subject Event of Loss, if requested by Lessor and at Lessor's expense, furnish a certified report of a qualified independent aircraft appraiser, reasonably satisfactory to Lessor, certifying that such Replacement Airframe and any such Replacement Engine complies with the value, utility and remaining useful life requirements set forth in Section 10.1.3(b).

Lessor and Lessee understand and agree that if at the time of any replacement of the Airframe or any Engine, as contemplated in this Section 10, the Airframe was registered in a jurisdiction other than the United States, then the requirements set forth above in this Section 10.3.1 relating to compliance with the requirements of the Act or the FAA, shall be deemed to refer to the comparable applicable Law of, and the Aviation Authority of, such other jurisdiction.

10.3.2 Other Obligations

(a) Lessor and Lessee agree that, upon any Replacement Airframe becoming the Airframe hereunder, and upon any Replacement Engine becoming an Engine hereunder, this Lease shall continue to be, and shall be treated as, a lease for U.S. federal income tax purposes of, among other things, such Replacement Airframe and such Replacement Engine. Without limiting the foregoing, Lessee and Lessor intend that Lessor shall, in all events, be entitled to the benefits of Section 1110 with respect to any Replacement Airframe or Replacement Engine and Lessee and Lessor shall cooperate and take such action as the other may reasonably request so as to ensure that Lessor shall be entitled to such benefits; provided that Lessor shall not be entitled to such benefits to the extent that immediately prior to any Replacement Engine becoming an Engine hereunder, the benefits of Section 1110 were not, solely by reason of a change in law or court interpretation thereof, available to Lessor or Mortgagee, as assignee of Lessor.

(b) No Event of Loss with respect to an Engine, or with respect to an Airframe, shall result in, or otherwise allow


-33-

or permit (other than as provided in Section 10.1.2(b)), any reduction, deferral, discharge or other change in the timing or amount of any Rent payable by Lessee hereunder, and (subject to such Section 10.1.2(b)) Lessee shall pay all such Rent and other amounts as though such Event of Loss had not occurred.

10.4 Conveyance to Lessee

Upon compliance by Lessee with the applicable terms of Sections 10.1.3, 10.2 and 10.3.1, Lessor will transfer to Lessee the Airframe or Engine, as the case may be, with respect to which such Event of Loss occurred, in accordance with Section 4.5.

10.5 Application of Payments

Any amounts, other than insurance proceeds in respect of damage or loss not constituting an Event of Loss (the application of which is provided for in Section 11), received at any time by Lessor, Lessee or any Permitted Sublessee from any Government Entity or any other Person in respect of any Event of Loss will be applied as follows:

10.5.1 Replacement of Airframe and Engines

If such amounts are received with respect to the Airframe, and any Engine installed thereon at the time of such Event of Loss, upon compliance by Lessee with the applicable terms of Section 10.1.3 with respect to the Event of Loss for which such amounts are received, such amounts shall be paid over to, or retained by, Lessee.

10.5.2 Loss of Engine

If such amounts are received with respect to an Engine (other than an Engine installed on the Airframe at the time such Airframe suffers an Event of Loss), upon compliance by Lessee with the applicable terms of Section 10.2.2 with respect to the Event of Loss for which such amounts are received, such amounts shall be paid over to, or retained by, Lessee.

10.5.3 Payment of Loss

(a) first, if the sum described in Section 10.1.2 has not then been paid in full by Lessee, such amounts shall be paid to Lessor (or to Mortgagee so long as Mortgagee has not given notice to Lessee that the Lien of the Trust Indenture has been duly discharged, except with respect to Excluded Payments) to the extent necessary to pay in full such sum;

(b) second, the remainder, if any, shall be paid to Lessee.

10.6 Requisition of Aircraft for Use

If any Government Entity shall requisition for use the Airframe and the Engines or engines installed thereon, and if the same does not constitute an Event of Loss, Lessee shall promptly notify Lessor and Mortgagee of such requisition and all of Lessee's obligations under this Agreement shall continue to the same extent as if such requisition had not occurred; provided, however, that if the Airframe and Engines or engines installed thereon are not returned to Lessor by Lessee at the end of the Term or within 180 days thereafter, and Lessor, upon notice given not less than 30 days nor more than 120 days before the end of the Term, shall have elected to treat such event as constituting an Event of Loss with respect to the Aircraft, Lessee shall then be deemed to have made the election set forth in Section 10.1.2 with the effect that Lessee shall be obligated to pay the Stipulated Loss Value and all other amounts payable pursuant to Section 10.1.2 with respect to the Aircraft as if an Event of Loss had occurred as of the end of the Term. If Lessor shall not have elected to treat such event as an Event of Loss, Lessee shall be obligated to return the Airframe and Engines or engines to Lessor pursuant to, and in all other respects to comply with the provisions of, Section 5 promptly upon their return by such Government Entity, and Lessee shall pay to Lessor upon such return an amount equal to the average daily Basic Rent or Renewal Rent, as the case may be, payable by Lessee during the Term for each day after the end of the Term to but excluding the day of such return, up to a maximum of 30 days.

If any Government Entity shall requisition for use any Engine but not the Airframe, Lessee will, if such requisition continues to the end of the Term, replace such Engine by complying with the applicable terms of Sections 10.2 and 10.3 to the same extent as if an Event of Loss had occurred with respect


-35-

to such Engine, and any payments received by Lessor or Lessee from such Government Entity with respect to such requisition shall be paid or retained in accordance with Section 10.5.2.

10.9 Application of Payments During Existence of a Special Default

Any amount described in this Section 10 that is payable or creditable to, or retainable by, Lessee shall not be paid or credited to, or retained by, Lessee if at the time such payment, credit or retention would otherwise occur a Special Default shall have occurred and be continuing, but shall instead be held by or paid over to Lessor (or to Mortgagee so long as Mortgagee has not given notice to Lessee that the Trust Indenture has been duly discharged) as security for the obligations of Lessee under this Lease and the other Lessee Operative Agreements and shall be invested pursuant to Section 4.4 hereof unless and until such amount is applied, at the option of Lessor, or upon the written request of Lessee to Lessor, from time to time during the continuance of a Special Default, to Lessee's obligations under this Lease as and when due, it being understood that any such application shall be made to such obligations of Lessee as Lessor may determine in its sole discretion. At such time as there shall not be continuing any Special Default, such amount shall be paid to Lessee to the extent not previously applied in accordance with this Section 10.9.

Lessee shall comply with, or cause to be complied with, each of the provisions of Annex D, which provisions are hereby incorporated by this reference as if set forth in full herein.

11.2 Insurance for Own Account

Nothing in Section 11 shall limit or prohibit (a) Lessee from maintaining the policies of insurance required under Annex D with higher limits than those specified in Annex D, or (b) Lessor, Mortgagee or Owner Participant from obtaining insurance for its own account (and any proceeds payable under such separate insurance shall be payable as provided in the policy relating thereto); provided, however, that no insurance may be obtained or maintained that would limit or otherwise adversely affect the coverage of any insurance required to be obtained or maintained by Lessee pursuant to this Section 11 and Annex D.

11.3 Indemnification by Government in Lieu of Insurance

Lessor agrees to accept, in lieu of insurance against any risk with respect to the Aircraft described in Annex D, indemnification from, or insurance provided by, the U.S. Government, or upon the written consent of Lessor, other Government Entity, against such risk in an amount that, when added to the amount of insurance (including permitted self-insurance), if any, against such risk that Lessee (or any Permitted Sublessee) may continue to maintain, in accordance with this Section 11, during the period of such requisition or transfer, shall be at least equal to the amount of insurance against such risk otherwise required by this Section 11.

11.4 Application of Insurance Proceeds

As between Lessor and Lessee, all insurance proceeds received as a result of the occurrence of an Event of Loss with respect to the Aircraft or any Engine under policies required to be maintained by Lessee pursuant to this Section 11 will be applied in accordance with Section 10.5.

11.5 Application of Payments During Existence of a Special Default

If a Special Default shall have occurred and be continuing at any time that an amount described in this Section 11 is payable or creditable to, or retainable by, Lessee, Lessee shall cause such amount to be paid over to Lessor (or to Mortgagee so long as Mortgagee has not given notice to Lessee that the Lien of the Trust Indenture has been duly discharged) as security for the obligations of Lessee under this Lease and shall be invested pursuant to Section 4.4 hereof unless and until such amount is applied, at the option of Lessor, or upon the written request of Lessee to Lessor, from time to time during the continuance of a Special Default, to Lessee's obligations under this Lease and the other Lessee Operative Agreements as and when due, it being understood that any such application shall be made to such obligations of Lessee as Lessor may determine in its sole discretion. At such time as there shall not be continuing any Special Default, such amount shall be paid to Lessee to the extent not previously applied in accordance with this Section 11.5.

SECTION 12. INSPECTION

(a) At all reasonable times Lessor, Mortgagee or the Owner Participant, and their respective authorized representatives (the "Inspecting Parties") may (not more than once every 12 months unless a Lease Event of Default has occurred and is continuing in which case such inspection right shall not be so limited) inspect the Aircraft, the Airframe and the Engines (including, without limitation, the Aircraft Documents) and any such Inspecting Party may make copies of such Aircraft Documents not reasonably deemed confidential by Lessee or such Permitted Sublessee.

(b) Any inspection of the Aircraft hereunder shall be limited to a visual, walk-around inspection and shall not include the opening of any panels, bays or other components of the Aircraft (although those otherwise open may be inspected), and no such inspection shall interfere with Lessee's or any

(d) Each Inspecting Party shall bear its own expenses in connection with any such inspection (including the cost of any copies made in accordance with Section 12(a)).

SECTION 13. ASSIGNMENT; MERGER; SUCCESSOR OWNER TRUSTEE

13.1 In General

This Lease and the other Lessee Operative Agreements shall be binding upon and inure to the benefit of Lessor and Lessee and their respective successors and permitted assigns. Except as otherwise expressly permitted by the terms of the Lease or any other Lessee Operative Agreement, Lessee will not, without the prior written consent of Lessor and Mortgagee, assign any of its rights under this Lease, such consent not to be unreasonably withheld. Except as otherwise provided herein (including, without limitation, under the provisions of Section 15 hereof), Lessor and Mortgagee may not assign or convey any of their right, title and interest in and to this Lease or the Aircraft without the prior written consent of Lessee, such consent not to be unreasonably withheld.

13.2 Merger of Lessee

13.2.1 In General

Lessee shall not consolidate with or merge into any other Person under circumstances in which Lessee is not the surviving corporation, or convey, transfer or lease in one or more transactions all or substantially all of its assets to any other Person, unless:

(b) such Person executes and delivers to Lessor and Mortgagee a duly authorized, legal, valid, binding and enforceable

(d) immediately after giving effect to such consolidation or merger no Lease Event of Default shall have occurred and be continuing.

13.2.2 Effect of Merger

Upon any such consolidation or merger of Lessee with or into, or the conveyance, transfer or lease by Lessee of all or substantially all of its assets to, any Person in accordance with this Section 13.2, such Person will succeed to, and be substituted for, and may exercise every right and power of, Lessee under the Lessee Operative Agreements with the same effect as if such person had been named as "Lessee" therein. No such consolidation or merger, or conveyance, transfer or lease, shall have the effect of releasing Lessee or such Person from any of the obligations, liabilities, covenants or undertakings of Lessee under the Lease.

13.3 Assignment Security for Lessor's Obligations

In order to secure the indebtedness evidenced by the Equipment Notes, Lessor has agreed in the Trust Indenture, among other things, to assign to Mortgagee this Lease and to mortgage the Aircraft, the Airframe and the Engines in favor of Mortgagee, subject to the reservations and conditions therein set forth. Lessee hereby accepts and consents to the assignment of all Lessor's right, title and interest in and to this Lease pursuant to the terms of the Trust Indenture.

Section 16 hereof. Notwithstanding the foregoing assignment of this Lease, the obligations of Lessee to Lessor


-40-

to perform the terms and conditions of this Lease shall remain in full force and effect.

Lessee agrees that in the case of the appointment of any successor Owner Trustee pursuant to the terms of the Participation Agreement and the Trust Agreement, such successor Owner Trustee shall, upon written notice by such successor Owner Trustee to Lessee, succeed to all the rights, powers and title of Lessor hereunder and shall be deemed to be Lessor and the owner of the Aircraft and the other assets of the Trust Estate for all purposes hereof without the necessity of any consent or approval by Lessee and without in any way altering the terms of this Lease or Lessee's obligations hereunder. An appointment and designation of a successor Owner Trustee shall not exhaust the right to appoint and designate further successor or additional Owner Trustees pursuant to the Participation Agreement and the Trust Agreement, and such right may be exercised repeatedly as long as this Lease shall be in effect.

SECTION 14. LEASE EVENTS OF DEFAULT

The occurrence of any one or more of the following circumstances, conditions, acts or events, for any reason whatsoever and whether any such circumstance, condition, act or event shall be voluntary or involuntary or come about or be effected by operation of Law or pursuant to or in compliance with any judgment, decree, order, rule or regulation of any Government Entity, shall constitute a Lease Event of Default so long as it shall not have been remedied:

14.4 Representations and Warranties

Any representation or warranty made by Lessee herein, in the Participation Agreement or in any other Lessee Operative Agreement (other than the representations and warranties of Lessee in the Tax Indemnity Agreement) (a) shall prove to have been untrue or inaccurate in any material respect as of the date made, (b) such untrue or inaccurate representation or warranty is material at the time in question, and (c) the same shall remain uncured (to the extent of the adverse impact of such incorrectness on the interest of the Participants or Lessor) for a period in excess of 30 days from and after the date of written notice thereof from Lessor or Mortgagee to Lessee.

Lessor shall give Lessee at least 15 days prior written notice of the date fixed for any public sale of the Airframe and/or any Engine or of the date on or after which will occur the execution of any contract providing for any private sale.

(ii) an amount equal to the excess, if any, of the Stipulated Loss Value for the Aircraft, computed as of the Stipulated Loss Value Date specified in such notice, over the Fair Market Sales Value of the Aircraft, as of the Stipulated Loss Value Date specified in such notice; plus

(a) at the Payment Due Rate from and including the date on which any such amount was due to the date of payment of such amount; plus

Section 3.3, as liquidated damages for


-45-

loss of a bargain and not as a penalty (in lieu of the Basic Rent or Renewal Rent, as the case may be, for the Aircraft in respect of all periods commencing on or after the date of such sale), the following amounts:

(a) all unpaid Basic Rent or Renewal Rent, as the case may be, due at any time prior to the Stipulated Loss Value Date on or immediately preceding the date of such sale; plus

(b) an amount equal to the excess, if any, of (i) the Stipulated Loss Value of the Aircraft, computed as of the Stipulated Loss Value Date used in the foregoing clause (a) for the computation of unpaid Rent, over (ii) the proceeds of such sale; plus

(c) all reasonable brokerage and other out-of-pocket fees and expenses incurred by Lessor and, Mortgagee in connection with such sale; plus

(d) if the date of such sale is not a Stipulated Loss Value Date, an amount equal to interest on the outstanding principal amount of the Equipment Notes at the rate per annum borne thereby from and including the Stipulated Loss Value Date used in the foregoing clause
(a) for the computation of unpaid Rent to the date of such sale; plus

(e) interest on the amounts specified in the foregoing clause
(a) at the Payment Due Rate from and including the date on which any such amount was due to the date of payment of such amount; plus

(f) interest on the sum of the amounts specified in the foregoing clause (b) at the Payment Due Rate from and including the date of such sale to the date of payment of such amounts.

15.1.5 Rescission

Lessor may (i) at its option, rescind or terminate this Lease as to the Aircraft, Airframe or any Engine, or any Part thereof, or (ii) exercise any other right or remedy that may be available to it under applicable Law or proceed by appropriate court action to enforce the terms hereof.

15.1.6 Other Remedies


-46-

(a) In addition to the foregoing remedies (but without duplication of amounts otherwise paid under this Section 15), Lessee shall be liable for any and all unpaid Rent due hereunder before, during or after (except as otherwise provided herein) the exercise of any of the foregoing remedies and for all reasonable attorneys' fees and other costs and expenses of Lessor, Mortgagee the Owner Participant and the Note Holders, including, without limitation, interest on overdue Rent at the rate as herein provided, incurred by reason of the occurrence of any Lease Event of Default or the exercise of Lessor's remedies with respect thereto, including all reasonable costs and expenses incurred in connection with the return of the Airframe or any Engine, in accordance with the terms of Section 5 or in placing the Airframe or any Engine, in the condition and airworthiness required by Section 5.

(b) The prevailing party in any dispute between Lessee and Lessor under this Lease shall be entitled to reimbursement from the other party for all reasonable attorneys' fees and other costs and expenses of such prevailing party, incurred by reason of such dispute.

15.2 Limitations Under CRAF

Notwithstanding the provisions of Section 15.1, during any period that the Aircraft, Airframe or any Engine is subject to CRAF in accordance with the provisions of Section 7.2.3 and in the possession of the U.S. Government, Lessor shall not, as a result of any Lease Event of Default, exercise its remedies hereunder in such manner as to limit Lessee's control under this Lease (or any Permitted Sublessee's control under any Permitted Sublease) of the Aircraft, Airframe or such Engine, unless at least 30 days' (or such other period as may then be applicable under CRAF) written notice of default hereunder shall have been given by Lessor or Mortgagee by registered or certified mail to Lessee (and any Permitted Sublessee) with a copy to the Contracting Officer Representative or Representatives for the Military Airlift Command of the United States Air Force to whom notices must be given under the contract governing Lessee's (or any Permitted Sublessee's) participation in CRAF with respect to the Aircraft, Airframe or any Engine.

15.3 Right to Perform for Lessee

If Lessee (i) fails to make any payment of Rent required to be made by it hereunder or (ii) fails to perform or comply with any of its agreements contained herein and such


-47-

failure continues for a period of 30 days after written notice thereof is given by Lessor or Mortgagee to Lessee, Lessor or Mortgagee may (but shall not be obligated to) make such payment or perform or comply with such agreement, and the amount of such payment and the amount of the expenses of Lessor or Mortgagee incurred in connection with such payment or the performance of or compliance with such agreement, as the case may be, together with interest thereon at the Payment Due Rate, shall be deemed Supplemental Rent, payable by Lessee upon demand by Lessor or Mortgagee, whichever is entitled thereto. No such payment, performance or compliance shall be deemed to cure any Lease Default or Lease Event of Default or otherwise relieve Lessee of its obligations with respect thereto.

15.4 Determination of Fair Market Rental Value and Fair Market Sales Value

For the purpose of this Section 15 only, the "Fair Market Rental Value" or the "Fair Market Sales Value" of the Aircraft, the Airframe or any Engine, shall be determined on an "as is, where is" basis and shall take into account customary brokerage and other out-of-pocket fees and expenses which typically would be incurred in connection with a re-lease or sale of the Aircraft, the Airframe or any Engine. Any such determination shall be made by an Appraiser selected by Lessor and the costs and expenses associated therewith shall be borne by Lessee, unless Lessor does not obtain possession of the Aircraft, the Airframe and the Engines pursuant to this Section 15, in which case an Appraiser shall not be appointed and Fair Market Rental Value and Fair Market Sales Value for purposes of this Section 15 shall be zero.

15.5 Remedies Cumulative

Nothing contained in this Lease shall be construed to limit in any way any right, power, remedy or privilege of Lessor hereunder or under any other Operative Agreement or now or hereafter existing at law or in equity. Each and every right, power, remedy and privilege hereby given to, or retained by, Lessor in this Lease shall be in addition to and not in limitation of every other right, power, remedy and privilege given under the Operative Agreements or now or hereafter existing at law or in equity. Each and every right, power, remedy and privilege of Lessor under this Lease and any other Operative Agreement may be exercised from time to time or simultaneously and as often and in such order as may be deemed expedient by Lessor. All such rights, powers, remedies and privileges shall be cumulative and not mutually exclusive, and the exercise of


-48-

one shall not be deemed a waiver of the right to exercise any other. Lessee hereby waives to the extent permitted by applicable Law any right which it may have to require Lessor to choose or elect remedies.

SECTION 16. LESSEE'S OBLIGATIONS; NO SETOFF, COUNTERCLAIM, ETC.

(a) Lessee's obligation to pay Rent hereunder shall be absolute and unconditional, and shall not be affected by any event or circumstance, including, without limitation: (i) any setoff, counterclaim, recoupment, defense or other right that Lessee may have against Lessor, Mortgagee, any Participant, any Note Holder, or any other Person for any reason whatsoever; (ii) any defect in the title, airworthiness, condition, design, operation or fitness for use of, or any damage to or loss or destruction of, the Aircraft, Airframe or any Engine, or any interruption or cessation in the use or possession thereof by Lessee for any reason whatsoever; (iii) any insolvency, bankruptcy, reorganization or similar proceedings by or against Lessee or any other Person; or (iv) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

(b) If for any reason whatsoever this Lease shall be terminated in whole or in part by operation of law or otherwise except as specifically provided herein, Lessee nonetheless agrees to pay an amount equal to each Rent payment at the time such payment would have become due and payable in accordance with the terms hereof had this Agreement not been terminated in whole or in part. Lessee hereby waives, to the extent permitted by applicable law, any and all rights that it may now have or that at any time hereafter may be conferred upon it, by statute or otherwise, to terminate, cancel, quit or surrender this Agreement, except in accordance with the express terms hereof.

(c) Nothing set forth in this Section 16 shall be construed to prohibit Lessee from separately pursuing any claim that it may have from time to time against Lessor or any other Person with respect to any matter (other than the absolute and unconditional nature of Lessee's obligations hereunder to pay Basic Rent, Renewal Rent, the Stipulated Loss Value with respect to any Aircraft, and the Termination Value with respect to any Aircraft and other than the matters specified in paragraphs (a) and (b) above).

17.1 Preliminary Notices

(a) At least (i) 120 days prior to the Scheduled Expiration Date or a Renewal Term Expiration Date, as applicable, or (ii) if a Renewal Lease Term of six months or less is then in effect, 60 days prior to the Renewal Term Expiration Date, Lessee may provide notice to Lessor that Lessee may exercise the option to extend the leasing of the Aircraft for a Renewal Lease Term pursuant to Section 17.2 or the option to purchase the Aircraft on the Scheduled Expiration Date or Renewal Term Expiration Date of such Renewal Lease Term, as the case may be, pursuant to Section 17.3 (a "Preliminary Notice").

(b) If any such Preliminary Notice is given by Lessee, then Lessee may provide a further notice specifying which option it intends to elect, with respect to the relevant period, pursuant to Section 17.2.1 or 17.3.1, as the case may be. If Lesser fails to provide such further notice, such Preliminary Notice shall be deemed revoked.

17.2 Renewal Options

17.2.1 Renewal Notice

(a) If Lessee has given a Preliminary Notice, as specified in
Section 17.1, and subject to the terms and conditions of this Section 17.2, Lessee may exercise its option to extend the leasing of the Aircraft hereunder until the applicable Renewal Term Expiration Date, on the same terms, provisions and conditions (except as contemplated by this Section 17) set forth herein and in the other Lessee Operative Agreements with respect to the Base Lease Term, by delivery of a notice (a "Renewal Notice") to Lessor not less than (i) 75 days prior to the Scheduled Expiration Date or a Renewal Term Expiration Date, as applicable, or (ii) if a Renewal Lease Term of six months or less is then in effect, 20 days prior to the Renewal Term Expiration Date.

(b) Notwithstanding anything to the contrary in this Agreement or any other Operative Agreement:

(i) No Renewal Notice shall be binding on Lessor or oblige Lessor to extend the leasing of the Aircraft hereunder for a Renewal Lease Term if any Lease Event of Default shall have occurred and be continuing on and as of


-50-

the date that such Renewal Lease Term would otherwise commence.

(ii) Any Renewal Notice shall be revocable by Lessee until 10 Business Days after the Renewal Rent is determined in accordance with

(iii) Lessee shall not be entitled to give any Renewal Notice if it has (x) not delivered a Preliminary Notice or (y) delivered a Purchase Notice to Lessor.

17.4 Appraisals

Whenever Fair Market Rental Value or Fair Market Sales Value of the Aircraft is required to be determined by an appraisal under the foregoing provisions of this Section 17, Lessee and Lessor shall, within seven days after the expiration of the 35-day period referred to in Sections 17.2.2(b), 17.2.3(c) and 17.3.2, appoint a mutually satisfactory Appraiser to complete such appraisal within seven days of the appointment


-53-

and the determination of such Appraiser shall be final and binding on Lessor and Lessee. If Lessee and Lessor fail to agree within such 7-day period upon a satisfactory Appraiser then each shall within one day thereafter appoint a separate Appraiser and such Appraisers shall within seven days of such appointment jointly determine such amount and such jointly determined amount shall be final and binding on Lessor and Lessee. If either Lessee or Lessor fails to so appoint an Appraiser, the determination of the single Appraiser appointed shall be final and binding on Lessor and Lessee. If two Appraisers are appointed and within seven days after the appointment of the latter of such two Appraisers, they cannot agree upon such amount, such two Appraisers shall, within two days after such seventh day, appoint a third Appraiser and such amount shall be determined by such three Appraisers, who shall make their separate appraisals within seven days following the appointment of the third Appraiser, and any determination so made shall be conclusive and binding upon Lessor and Lessee in accordance with the following provisions of this Section
17. If three Appraisers are appointed and the difference between the determination which is farther from the middle determination and the middle determination is more than 125% of the difference between the middle determination and the third determination, then such farther determination shall be excluded, the remaining two determinations shall be averaged and such average shall be final and binding upon Lessor and Lessee. Otherwise, the average of all three determinations shall be final and binding upon Lessor and Lessee. If no such third Appraiser is appointed within such 2-day period, either Lessor or Lessee may apply to the American Arbitration Association to make such appointment, and both parties shall cooperate in making, and be bound by, such appointment. The fees and expenses of all such Appraisers and such appraisal procedure shall be borne equally by Lessee and Lessor; provided, that if Lessee elects not to renew this Lease or purchase the Aircraft following the conclusion of such appraisal, Lessee shall pay all such fees and expenses of such appraisal.

TO HAVE AND TO HOLD all and singular the aforesaid property unto the Mortgagee, and its successors and assigns, in trust for the equal and proportionate benefit and security of the Loan Participants, the Note Holders and the Indenture Indemnitees, except as provided in Section 2.14 and Article III hereof without any preference, distinction or priority of any one Equipment Note over any other by reason of priority of time of issue, sale, negotiation, date of maturity thereof or otherwise for any reason whatsoever, and for the uses and purposes, and in all cases and as to all property specified in paragraphs (1) through (8) inclusive above, subject to the terms and provisions set forth in this Trust Indenture.

It is expressly agreed that anything herein contained to the contrary notwithstanding, the Owner Trustee shall remain liable under the Indenture Agreements to perform all of the obligations assumed by it thereunder, except to the extent prohibited or excluded from doing so pursuant to the terms and provisions thereof, and the Mortgagee, the Loan Participants, the Note Holders and the Indenture Indemnitees shall have no obligation or liability under the Indenture Agreements by reason of or arising out of the assignment hereunder, nor shall the Mortgagee, the Loan Participants, the Note Holders or the Indenture Indemnitees be required or obligated in any manner to perform or fulfill any obligations of the Owner Trustee under or pursuant to the Indenture Agreements, or, except as herein expressly provided, to make any payment, or to make any inquiry as to the nature or sufficiency of any payment received by it, or present or file any claim, or take any action to collect or enforce the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

The Owner Trustee does hereby constitute the Mortgagee the true and lawful attorney of the Owner Trustee, irrevocably, granted for good and valuable consideration and coupled with an interest and with full power of substitution, and with full power (in the name of the Owner Trustee or otherwise) to ask for, require, demand, receive, compound and give acquittance for any and all monies and claims for monies (in each case including insurance and requisition proceeds but in all cases excluding Excluded Payments) due and to become due under or arising out of the Indenture Agreements, and all other property which now or hereafter constitutes part of the Trust Indenture Estate, to endorse any checks or other instruments or orders in connection therewith and to file any claims or to take any action or to institute any proceedings which the Mortgagee may deem to be necessary or advisable in the premises. Without limiting the generality of the foregoing, but subject to the rights of the Owner Trustee and the Owner Participant under Sections 2.13, 4.03 and 4.04(a) hereof, during the continuance of any Event of Default under this Trust Indenture, the Mortgagee shall have the right under such power of attorney to accept any offer in connection with the exercise of


-6-

remedies as set forth herein of any purchaser to purchase the Airframe and Engines and upon such purchase to execute and deliver in the name of and on behalf of the Owner Trustee an appropriate bill of sale and other instruments of transfer relating to the Airframe and Engines, when purchased by such purchaser, and to perform all other necessary or appropriate acts with respect to any such purchase, and in its discretion to file any claim or take any other action or proceedings, either in its own name or in the name of the Owner Trustee or otherwise, which the Mortgagee may deem necessary or appropriate to protect and preserve the right, title and interest of the Mortgagee in and to such Rents and other sums and the security intended to be afforded hereby; provided, however, that no action of the Mortgagee pursuant to this paragraph shall increase the obligations or liabilities of the Owner Trustee to any Person beyond those obligations and liabilities specifically set forth in this Trust Indenture and in the other Operative Agreements. Under the Lease, Lessee is directed, so long as this Trust Indenture shall not have been fully discharged, to make all payments of Rent (other than Excluded Payments) and all other amounts which are required to be paid to or deposited with the Owner Trustee pursuant to the Lease (other than Excluded Payments) directly to, or as directed by, the Mortgagee at such address or addresses as the Mortgagee shall specify, for application as provided in this Trust Indenture. The Owner Trustee agrees that promptly upon receipt thereof, it will transfer to the Mortgagee any and all monies from time to time received by it constituting part of the Trust Indenture Estate, for distribution by the Mortgagee pursuant to this Trust Indenture, except that the Owner Trustee shall accept for distribution pursuant to the Trust Agreement any amounts distributed to it by the Mortgagee under this Trust Indenture.

The Owner Trustee agrees that at any time and from time to time, upon the written request of the Mortgagee, the Owner Trustee will promptly and duly execute and deliver or cause to be duly executed and delivered any and all such further instruments and documents as the Mortgagee may reasonably deem necessary or desirable to perfect, preserve or protect the mortgage, security interests and assignments created or intended to be created hereby or to obtain for the Mortgagee the full benefits of the assignment hereunder and of the rights and powers herein granted.

The Owner Trustee does hereby warrant and represent that it has not assigned or pledged, and hereby covenants and agrees that it will not assign or pledge, so long as the assignment hereunder shall remain in effect, and the Lien hereof shall not have been released pursuant to Section 10.01 hereof, any of its right, title or interest hereby assigned, to anyone other than the Mortgagee, and that it will not, except as otherwise provided in this Trust Indenture and except with respect to Excluded Payments to which it is entitled, (i) accept any payment from Lessee under any Indenture Agreement, (ii) enter into any agreement amending or supplementing any Indenture Agreement, (iii) execute any waiver or modification of, or consent under, the terms of, or exercise any rights, powers or privileges under, any Indenture Agreement, (iv) settle or compromise any claim arising under any Indenture Agreement or (v)


-7-

submit or consent to the submission of any dispute, difference or other matter arising under or in respect of any Indenture Agreement to arbitration thereunder.

The Owner Trustee does hereby agree that it will not without the written consent of the Mortgagee:

(a) receive or collect or agree to the receipt or collection of any payment (other than Excluded Payments) of Rent, including Basic Rent, Stipulated Loss Value, Termination Value or any other payment to be made pursuant to
Section 9 or 10 of the Lease prior to the date for the payment thereof provided for by the Lease or assign, transfer or hypothecate (other than to the Mortgagee hereunder) any payment of Rent, including Basic Rent, Stipulated Loss Value, Termination Value or any other payment (other than Excluded Payments) to be made pursuant to Section 9 or 10 of the Lease, then due or to accrue in the future under the Lease in respect of the Airframe and Engines; or

(b) except as contemplated by the Trust Agreement in connection with the appointment of a successor owner trustee, sell, mortgage, transfer, assign or hypothecate (other than to the Mortgagee hereunder) its interest in the Airframe and Engines or any part thereof or in any amount to be received by it from the use or disposition of the Airframe and Engines, other than amounts distributed to it pursuant to Article III hereof.

It is hereby further agreed that any and all property granted, bargained, sold, assigned, transferred, conveyed, mortgaged, pledged or confirmed in the granting clauses hereof which is hereafter acquired by the Owner Trustee shall ipso facto, and without any other conveyance, assignment or act on the part of the Owner Trustee or the Mortgagee, become and be subject to the Lien herein granted as fully and completely as though specifically described herein, but nothing contained in this paragraph shall be deemed to modify or change the obligations of the Owner Trustee contained in the foregoing paragraphs.

The Owner Trustee does hereby ratify and confirm the Lease and does hereby agree that it will not violate any covenant or agreement made by it therein, herein or in any other Owner Trustee Agreement.

Notwithstanding the Granting Clause or any of the preceding paragraphs, there is hereby excluded from the foregoing grant, bargain, sale, assignment, transfer, conveyance, mortgage, pledge and security interest all Excluded Payments. Further, nothing in the Granting Clause or the preceding paragraphs shall impair any of the rights of the Owner Trustee or the Owner Participant under Section 2.13, 4.03, 4.04, 4.08, 5.02 or 5.03 hereof.

IT IS HEREBY COVENANTED AND AGREED by and between the parties hereto as follows:

SECTION 2.02. ISSUANCE AND TERMS OF EQUIPMENT NOTES

The Equipment Notes shall be dated the date of issuance thereof, shall be issued in up to three separate series consisting of Series A, Series B and Series C and in the maturities and principal amounts and shall bear interest as specified in Schedule I hereto. On the date of the consummation of the Transaction, each Equipment Note shall be issued to the Subordination Agent on behalf of the Pass Through Trustees under the Pass Through Trust Agreements. The Equipment Notes shall be issued in registered form only. The Equipment Notes shall be issued in denominations of $1,000 and integral multiples thereof, except that one Equipment Note of each Series may be in an amount that is not an integral multiple of $1,000.

Each Equipment Note shall bear interest at the applicable Debt Rate (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on the unpaid Original Amount thereof from time to time outstanding, payable in arrears in semiannual installments


-14-

commencing on _____________, ____, and on each _______ _ and _______ _ thereafter until maturity. The Original Amount of each Equipment Note shall be payable on the dates and in the installments equal to the corresponding percentage of the Original Amount as set forth in Schedule I hereto, the applicable portion of which shall be attached as Schedule I to such Equipment Notes. Notwithstanding the foregoing, the final payment made under each Equipment Note shall be in an amount sufficient to discharge in full the unpaid Original Amount and all accrued and unpaid interest on, and any other amounts due under, such Equipment Note. Each Equipment Note shall bear interest at the Payment Due Rate (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any part of the Original Amount, Make-Whole Amount, if any, and, to the extent permitted by applicable Law, interest and any other amounts payable thereunder not paid when due for any period during which the same shall be overdue, in each case for the period the same is overdue. Amounts shall be overdue if not paid when due (whether at stated maturity, by acceleration or otherwise). Notwithstanding anything to the contrary contained herein, if any date on which a payment under any Equipment Note becomes due and payable is not a Business Day then such payment shall not be made on such scheduled date but shall be made on the next succeeding Business Day and if such payment is made on such next succeeding Business Day, no interest shall accrue on the amount of such payment during such extension.

The Owner Trustee agrees to pay to the Mortgagee for distribution in accordance with Section 3.04 hereof: (i) to the extent not payable (whether or not in fact paid) under Section 6(a) of the Note Purchase Agreement (as originally in effect or amended with the consent of the Owner Participant), an amount equal to the fees payable to the relevant Liquidity Provider under
Section 2.03 of each Liquidity Facility and the related Fee Letter (as defined in the Intercreditor Agreement) multiplied by a fraction the numerator of which shall be the then outstanding aggregate principal amount of the Series A Equipment Notes, Series B Equipment Notes and Series C Equipment Notes and the denominator of which shall be the then outstanding aggregate principal amount of all "Series A Equipment Notes," "Series B Equipment Notes" and "Series C Equipment Notes" (each as defined in the Note Purchase Agreement); (ii) (x) the amount equal to interest on any Downgrade Advance (other than any Applied Downgrade Advance) payable under Section 3.07(e) of each Liquidity Facility minus Investment Earnings from such Downgrade Advance multiplied by (y) the fraction specified in the foregoing clause (i); (iii) (x) the amount equal to interest on any Non-Extension Advance (other than any Applied Non-Extension Advance) payable under Section 3.07(a)(i) of each Liquidity Facility minus Investment Earnings from such Non-Extension Advance multiplied by (y) the fraction specified in the foregoing clause (i); (iv) if any payment default shall have occurred and be continuing with respect to interest on any Series A Equipment Note, Series B Equipment Note or Series C Equipment Note, (x) the excess, if any, of (1) the amount equal to interest on any Unpaid Advance, Applied Downgrade Advance or Applied Non-Extension Advance payable under Section 3.07(a)(i) of each Liquidity Facility over (2) the


-15-

sum of Investment Earnings from any Final Advance plus any amount of interest at the Payment Due Rate actually payable (whether or not in fact paid) by the Owner Trustee on the overdue scheduled interest on the Equipment Notes in respect of which such Unpaid Advance, Applied Downgrade Advance or Applied Non-Extension Advance was made multiplied by (y) a fraction the numerator of which shall be the then aggregate overdue amounts of interest on the Series A Equipment Notes, Series B Equipment Notes and Series C Equipment Notes (other than interest becoming due and payable solely as a result of acceleration of any such Equipment Notes) and the denominator of which shall be the then aggregate overdue amounts of interest on all "Series A Equipment Notes," "Series B Equipment Notes" and "Series C Equipment Notes" (each as defined in the Note Purchase Agreement) (other than interest becoming due and payable solely as a result of acceleration of any such "Equipment Notes") and (v) any other amounts owed to the Liquidity Provider by the Subordination Agent as borrower under each Liquidity Facility (other than amounts due as repayment of advances thereunder or as interest on advances) except to the extent payable pursuant to clause (i),
(ii), (iii) or (iv) above multiplied by the fraction specified in the foregoing clause (i). For purposes of this paragraph, the terms "Applied Downgrade Advance," "Applied Non-Extension Advance," "Cash Collateral Account," "Downgrade Advance," "Final Advance," "Investment Earnings," "Non-Extension Advance" and "Unpaid Advance" shall have the meanings specified in each Liquidity Facility.

The Equipment Notes shall be executed on behalf of the Owner Trustee by its President or one of its Vice Presidents, Assistant Vice Presidents or Assistant Secretaries or other authorized officer. Equipment Notes bearing the signatures of individuals who were at any time the proper officers of the Owner Trustee shall bind the Owner Trustee, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Equipment Notes or did not hold such offices at the respective dates of such Equipment Notes. The Owner Trustee may from time to time execute and deliver Equipment Notes with respect to the Aircraft to the Mortgagee for authentication upon original issue and such Equipment Notes shall thereupon be authenticated and delivered by the Mortgagee upon the written request of the Owner Trustee signed by a Vice President or Assistant Vice President or other authorized officer of the Owner Trustee; provided, however, that each such request shall specify the aggregate Original Amount of all Equipment Notes to be authenticated hereunder on original issue with respect to the Aircraft. No Equipment Note shall be secured by or entitled to any benefit under this Trust Indenture or be valid or obligatory for any purposes, unless there appears on such Equipment Note a certificate of authentication in the form provided for herein executed by the Mortgagee by the manual signature of one of its authorized officers and such certificate upon any Equipment Notes be conclusive evidence, and the only evidence, that such Equipment Note has been duly authenticated and delivered hereunder.


-16-

The aggregate Original Amount of the Equipment Notes issued hereunder shall not exceed 80% of Lessor's Cost.

SECTION 2.03. PAYMENTS FROM TRUST INDENTURE ESTATE ONLY

(a) Without impairing any of the other rights, powers, remedies, privileges, liens or security interests of the Note Holders under this Trust Indenture, each Note Holder, by its acceptance of an Equipment Note, agrees that as between it and the Owner Trustee, except as expressly provided in this Trust Indenture, the Participation Agreement or any other Operative Agreement, (i) the obligation to make all payments of the Original Amount of, interest on, Make-Whole Amount, if any, and all other amounts due with respect to the Equipment Notes, and the performance by the Owner Trustee of every obligation or covenant contained in this Trust Indenture and in the Participation Agreement or any of the other Operative Agreements, shall be payable only from the income and proceeds from the Trust Estate to the extent included in the Trust Indenture Estate and only to the extent that the Owner Trustee shall have sufficient income or proceeds from the Trust Estate to the extent included in the Trust Indenture Estate to enable the Mortgagee to make such payments in accordance with the terms of Article III hereof, and all of the statements, representations, covenants and agreements made by the Owner Trustee (when made in such capacity) contained in this Trust Indenture and any agreement referred to herein other than the Trust Agreement, unless expressly otherwise stated, are made and intended only for the purpose of binding the Trust Estate and establishing the existence of rights and remedies which can be exercised and enforced against the Trust Estate; therefore, anything contained in this Trust Indenture or such other agreements to the contrary notwithstanding (except for any express provisions or representations that the Owner Trustee is responsible for, or is making, in its individual capacity, for which there would be personal liability of the Owner Trustee), no recourse shall be had with respect to this Trust Indenture or such other agreements against the Owner Trustee in its individual capacity or against any institution or person which becomes a successor trustee or co-trustee or any officer, director, trustee, servant or direct or indirect parent or controlling Person or Persons of any of them, and
(ii) none of the Owner Trustee, in its individual capacity, the Owner Participant, the Mortgagee and any officer, director, trustee, servant, employee, agent or direct or indirect parent or controlling Person or Persons of any of them shall have any personal liability for any amounts payable hereunder, under the Participation Agreement or any of the other Operative Agreements or under the Equipment Notes except as expressly provided herein, in the Lease or in the Participation Agreement; provided, however, that nothing contained in this Section 2.03(a) shall be construed to limit the exercise and enforcement in accordance with the terms of this Trust Indenture or such other agreements of rights and remedies against the Trust Indenture Estate.

(b) If (i) all or any part of the Trust Estate becomes the property of, or the Owner Trustee or Owner Participant becomes, a debtor subject to the reorganization provisions


-17-

of the Bankruptcy Code, (ii) pursuant to such reorganization provisions, including Section 1111(b) of the Bankruptcy Code, the Owner Trustee (in its individual capacity) or the Owner Participant is required, by reason of the Owner Trustee (in its individual capacity) or the Owner Participant being held to have recourse liability to any Note Holder or the Mortgagee, directly or indirectly (other than the recourse liability of the Owner Trustee (in its individual capacity) or the Owner Participant under the Participation Agreement, the Lease or this Trust Indenture or by separate agreement), to make payment on account of any amount payable as principal, Make-Whole Amount, if any, interest or other amounts on the Equipment Notes and (iii) any Note Holder or the Mortgagee actually receives any Excess Amount (as hereinafter defined) which reflects any payment by the Owner Trustee (in its individual capacity) or the Owner Participant on account of clause (ii) above, then such Note Holder or the Mortgagee, as the case may be, shall promptly refund to the Owner Trustee (in its individual capacity) or the Owner Participant (whichever shall have made such payment) such Excess Amount.

For purposes of this Section 2.03(b), "Excess Amount" means the amount by which such payment exceeds the amount that would have been received by a Note Holder or the Mortgagee if the Owner Trustee (in its individual capacity) or the Owner Participant had not become subject to the recourse liability referred to in clause (ii) above. Nothing contained in this Section 2.03(b) shall prevent a Note Holder or the Mortgagee from enforcing any personal recourse obligation (and retaining the proceeds thereof) of the Owner Trustee (in its individual capacity) or the Owner Participant under the Participation Agreement, the Lease or this Trust Indenture (and any exhibits or annexes hereto or thereto) or from retaining any amount paid by Owner Participant under Section 2.13 or 4.03 hereof.

SECTION 2.04. METHOD OF PAYMENT

(a) The Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due under each Equipment Note or hereunder will be payable in Dollars by wire transfer of immediately available funds not later than 12 noon, New York City time, on the due date of payment to the Mortgagee at the Corporate Trust Office for distribution among the Note Holders in the manner provided herein. The Owner Trustee shall not have any responsibility for the distribution of such payment to any Note Holder. Notwithstanding the foregoing or any provision in any Equipment Note to the contrary, the Mortgagee will use reasonable efforts to pay or cause to be paid, if so directed in writing by any Note Holder (with a copy to the Owner Trustee), all amounts paid by the Owner Trustee hereunder and under such holder's Equipment Note or Equipment Notes to such holder or a nominee therefor (including all amounts distributed pursuant to Article III of this Trust Indenture) by transferring, or causing to be transferred, by wire transfer of immediately available funds in Dollars, prior to 12:30 p.m., New York City time, on the due date of payment, to an account maintained by such holder with a bank located in the continental United States the amount to be


-18-

distributed to such holder, for credit to the account of such holder maintained at such bank. Any payment made hereunder shall be made without any presentment or surrender of any Equipment Note, except that, in the case of the final payment in respect of any Equipment Note, such Equipment Note shall be surrendered to the Mortgagee for cancellation promptly after such payment. Notwithstanding any other provision of this Trust Indenture to the contrary, the Mortgagee shall not be required to make, or cause to be made, wire transfers as aforesaid prior to the first Business Day on which it is practicable for the Mortgagee to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 12:30 p.m., New York City time, at the place of payment. Prior to the due presentment for registration of transfer of any Equipment Note, the Owner Trustee and the Mortgagee shall deem and treat the Person in whose name any Equipment Note is registered on the Equipment Note Register as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable with respect to such Equipment Note and for all other purposes, and none of the Owner Trustee or the Mortgagee shall be affected by any notice to the contrary. So long as any signatory to the Participation Agreement or nominee thereof shall be a registered Note Holder, all payments to it shall be made to the account of such Note Holder specified in Schedule I thereto and otherwise in the manner provided in or pursuant to the Participation Agreement unless it shall have specified some other account or manner of payment by notice to the Mortgagee consistent with this Section 2.04.

(b) The Mortgagee, as agent for the Owner Trustee, shall exclude and withhold at the appropriate rate from each payment of Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due hereunder or under each Equipment Note (and such exclusion and withholding shall constitute payment in respect of such Equipment Note) any and all United States withholding taxes applicable thereto as required by Law. The Mortgagee agrees to act as such withholding agent and, in connection therewith, whenever any present or future United States taxes or similar charges are required to be withheld with respect to any amounts payable hereunder or in respect of the Equipment Notes, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of the Note Holders, that it will file any necessary United States withholding tax returns or statements when due, and that as promptly as possible after the payment thereof it will deliver to each Note Holder (with a copy to the Owner Trustee and the Lessee) appropriate receipts showing the payment thereof, together with such additional documentary evidence as any such Note Holder may reasonably request from time to time.

If a Note Holder which is a Non-U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form 1001 or W-8 (or such successor form or forms as may be required by the United States Treasury Department) during the calendar year in which the payment hereunder or under the


-19-

Equipment Note(s) held by such holder is made (but prior to the making of such payment), or in either of the two preceding calendar years, and has not notified the Mortgagee of the withdrawal or inaccuracy of such form prior to the date of such payment (and the Mortgagee has no reason to believe that any information set forth in such form is inaccurate), the Mortgagee shall withhold only the amount, if any, required by Law (after taking into account any applicable exemptions properly claimed by the Note Holder) to be withheld from payments hereunder or under the Equipment Notes held by such holder in respect of United States federal income tax. If a Note Holder (x) which is a Non-U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form 4224 in duplicate (or such successor certificate, form or forms as may be required by the United States Treasury Department as necessary in order to properly avoid withholding of United States federal income tax), for each calendar year in which a payment is made (but prior to the making of any payment for such year), and has not notified the Mortgagee of the withdrawal or inaccuracy of such certificate or form prior to the date of such payment (and the Mortgagee has no reason to believe that any information set forth in such form is inaccurate) or (y) which is a U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W-9, if applicable, prior to a payment hereunder or under the Equipment Notes held by such holder, no amount shall be withheld from payments in respect of United States federal income tax. If any Note Holder has notified the Mortgagee that any of the foregoing forms or certificates is withdrawn or inaccurate, or if such holder has not filed a form claiming an exemption from United States withholding tax or if the Code or the regulations thereunder or the administrative interpretation thereof is at any time after the date hereof amended to require such withholding of United States federal income taxes from payments under the Equipment Notes held by such holder, the Mortgagee agrees to withhold from each payment due to the relevant Note Holder withholding taxes at the appropriate rate under Law and will, on a timely basis as more fully provided above, deposit such amounts with an authorized depository and make such returns, statements, receipts and other documentary evidence in connection therewith as required by Law.

Neither the Owner Trustee nor the Owner Participant shall have any liability for the failure of the Mortgagee to withhold taxes in the manner provided for herein or for any false, inaccurate or untrue evidence provided by any Note Holder hereunder.

SECTION 2.05. APPLICATION OF PAYMENTS

In the case of each Equipment Note, each payment of Original Amount, Make-Whole Amount, if any, and interest due thereon shall be applied:

First: to the payment of accrued interest on such Equipment Note (as well as any interest on any overdue Original Amount, any overdue Make-Whole Amount, if


-20-

any, and to the extent permitted by Law, any overdue interest and any other overdue amounts thereunder) to the date of such payment;

Second: to the payment of the Original Amount of such Equipment Note (or a portion thereof) then due thereunder;

Third: to the payment of Make-Whole Amount, if any, and any other amount due hereunder or under such Equipment Note; and

Fourth: the balance, if any, remaining thereafter, to the payment of the Original Amount of such Equipment Note remaining unpaid (provided that such Equipment Note shall not be subject to redemption except as provided in Sections 2.10, 2.11 and 2.12 hereof).

The amounts paid pursuant to clause "Fourth" above shall be applied to the installments of Original Amount of such Equipment Note in the inverse order of their normal maturity.

SECTION 2.06. TERMINATION OF INTEREST IN TRUST INDENTURE ESTATE

No Note Holder nor any other Indenture Indemnitee shall, as such, have any further interest in, or other right with respect to, the Trust Indenture Estate when and if the Original Amount of, Make-Whole Amount, if any, and interest on and other amounts due under all Equipment Notes held by such Note Holder and all other sums then due and payable to such Note Holder, such Indenture Indemnitee or the Mortgagee hereunder (including, without limitation, under the third paragraph of Section 2.02 hereof) and under the other Operative Agreements by the Owner Trustee and the Lessee (collectively, the "Secured Obligations") shall have been paid in full.

SECTION 2.07. REGISTRATION TRANSFER AND EXCHANGE OF EQUIPMENT NOTES

The Mortgagee shall keep a register (the "Equipment Note Register") in which the Mortgagee shall provide for the registration of Equipment Notes and the registration of transfers of Equipment Notes. No such transfer shall be given effect unless and until registration hereunder shall have occurred. The Equipment Note Register shall be kept at the Corporate Trust Office of the Mortgagee. The Mortgagee is hereby appointed "Equipment Note Registrar" for the purpose of registering Equipment Notes and transfers of Equipment Notes as herein provided. A holder of any Equipment Note intending to exchange such Equipment Note shall surrender such Equipment Note to the Mortgagee at the Corporate Trust Office,


-21-

together with a written request from the registered holder thereof for the issuance of a new Equipment Note, specifying, in the case of a surrender for transfer, the name and address of the new holder or holders. Upon surrender for registration of transfer of any Equipment Note, the Owner Trustee shall execute, and the Mortgagee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Equipment Notes of a like aggregate Original Amount and of the same series. At the option of the Note Holder, Equipment Notes may be exchanged for other Equipment Notes of any authorized denominations of a like aggregate Original Amount, upon surrender of the Equipment Notes to be exchanged to the Mortgagee at the Corporate Trust Office. Whenever any Equipment Notes are so surrendered for exchange, the Owner Trustee shall execute, and the Mortgagee shall authenticate and deliver, the Equipment Notes which the Note Holder making the exchange is entitled to receive. All Equipment Notes issued upon any registration of transfer or exchange of Equipment Notes (whether under this Section 2.07 or under Section 2.08 hereof or otherwise under this Trust Indenture) shall be the valid obligations of the Owner Trustee evidencing the same respective obligations, and entitled to the same security and benefits under this Trust Indenture, as the Equipment Notes surrendered upon such registration of transfer or exchange. Every Equipment Note presented or surrendered for registration of transfer shall (if so required by the Mortgagee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Mortgagee duly executed by the Note Holder or such holder's attorney duly authorized in writing, and the Mortgagee shall require evidence satisfactory to it as to the compliance of any such transfer with the Securities Act, and the securities Laws of any applicable state. The Mortgagee shall make a notation on each new Equipment Note of the amount of all payments of Original Amount previously made on the old Equipment Note or Equipment Notes with respect to which such new Equipment Note is issued and the date to which interest on such old Equipment Note or Equipment Notes has been paid. Interest shall be deemed to have been paid on such new Equipment Note to the date on which interest shall have been paid on such old Equipment Note, and all payments of the Original Amount marked on such new Equipment Note, as provided above, shall be deemed to have been made thereon. The Owner Trustee shall not be required to exchange any surrendered Equipment Notes as provided above during the ten-day period preceding the due date of any payment on such Equipment Note. The Owner Trustee shall in all cases deem the Person in whose name any Equipment Note shall have been issued and registered as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable by the Owner Trustee with respect to such Equipment Note and for all purposes until a notice stating otherwise is received from the Mortgagee and such change is reflected on the Equipment Note Register. The Mortgagee will promptly notify the Owner Trustee and the Lessee of each registration of a transfer of an Equipment Note. Any such transferee of an Equipment Note, by its acceptance of an Equipment Note, agrees to the provisions of the Participation Agreement applicable to Note Holders, and shall be deemed to have covenanted to the parties to the Participation Agreement as to the matters covenanted by the


-22-

original Loan Participant in the Participation Agreement. Subject to compliance by the Note Holder and its transferee (if any) of the requirements set forth in this Section 2.07, Mortgagee and Owner Trustee shall use all reasonable efforts to issue new Equipment Notes upon transfer or exchange within 10 Business Days of the date an Equipment Note is surrendered for transfer or exchange.

SECTION 2.08. MUTILATED, DESTROYED, LOST OR STOLEN EQUIPMENT NOTES

If any Equipment Note shall become mutilated, destroyed, lost or stolen, the Owner Trustee shall, upon the written request of the holder of such Equipment Note, execute and the Mortgagee shall authenticate and deliver in replacement thereof a new Equipment Note, payable in the same Original Amount dated the same date and captioned as issued in connection with the Aircraft. If the Equipment Note being replaced has become mutilated, such Equipment Note shall be surrendered to the Mortgagee and a photocopy thereof shall be furnished to the Owner Trustee. If the Equipment Note being replaced has been destroyed, lost or stolen, the holder of such Equipment Note shall furnish to the Owner Trustee and the Mortgagee such security or indemnity as may be required by them to save the Owner Trustee and the Mortgagee harmless and evidence satisfactory to the Owner Trustee and the Mortgagee of the destruction, loss or theft of such Equipment Note and of the ownership thereof. If a "qualified institutional buyer" of the type referred to in paragraph (a)(1)(i)(A), (B), (D) or (E) of Rule 144A under the Securities Act (a "QIB") is the holder of any such destroyed, lost or stolen Equipment Note, then the written indemnity of such QIB, signed by an authorized officer thereof, in favor of, delivered to and in form reasonably satisfactory to Lessee, Owner Trustee and Mortgagee shall be accepted as satisfactory indemnity and security and no further indemnity or security shall be required as a condition to the execution and delivery of such new Equipment Note. Subject to compliance by the Note Holder of the requirements set forth in this Section 2.08, Mortgagee and Owner Trustee shall use all reasonable efforts to issue new Equipment Notes within 10 Business Days of the date of the written request therefor from the Note Holder.

SECTION 2.09. PAYMENT OF EXPENSES ON TRANSFER; CANCELLATION

(a) No service charge shall be made to a Note Holder for any registration of transfer or exchange of Equipment Notes, but the Mortgagee, as Equipment Note Registrar, may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Equipment Notes.


-23-

-26-

but not including, the date of purchase and all other Secured Obligations owed, or then due and payable hereunder, to the holder thereof (including under the third paragraph of Section 2.02 hereof). Such option to purchase the Equipment Notes may be exercised (x) upon a Mortgagee Event described in clause (i) of the definition thereof or (y) in the event there shall have occurred and be continuing a Lease Event of Default or (z) upon either the Equipment Notes becoming due and payable pursuant to Section 4.04(b) hereof or the Mortgagee taking action or notifying the Owner Trustee that it intends to take action to foreclose the Lien of this Trust Indenture or otherwise commence the exercise of any significant remedy under this Trust Indenture or the Lease, provided that if such option is exercised pursuant to clause (y) when there shall have occurred and be continuing for less than 180 days a Lease Event of Default, the purchase price thereof shall equal the price provided in the preceding sentence plus the Make-Whole Amount, if any.

Such option to purchase the Equipment Notes may be exercised by the Owner Trustee or the Owner Participant giving irrevocable written notice of its election of such option to the Mortgagee, which notice shall specify a date for such purchase within 15 days of the date of such notice.

-27-

III hereof, it will hold any amount so received in trust for the Senior Holder (as defined in Section 2.14(c) hereof) and will forthwith turn over such payment to the Mortgagee in the form received to be applied as provided in Article III hereof.

                  that if an Event of Default shall have occurred and be
                  continuing, then such balance as shall not constitute Excluded
                  Payments shall not be distributed as provided in this clause
                  "Second" but shall be held by the Mortgagee as part of the
                  Trust Indenture Estate and invested in accordance with Section
                  5.09 hereof until whichever of the following shall first

(f) the Owner Trustee will not enter into any business or other activity other than the business of owning the Aircraft, the leasing thereof to Lessee and the carrying out of the transactions contemplated hereby and by the Lease, the Participation Agreement and the Trust Agreement and the other Operative Agreements.

SECTION 4.02. EVENT OF DEFAULT

"Event of Default" means any of the following events (whatever the reason for such Event of Default and whether such event shall be voluntary or involuntary or come about or be effected by operation of Law or pursuant to or in compliance with any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(a) any Lease Event of Default (provided that any such Lease Event of Default caused solely by a failure of Lessee to pay to the Owner Trustee or the Owner Participant when due any amount that is included in the definition of Excluded Payments shall not constitute an Event of Default unless notice is given by the Owner Participant to the Mortgagee that such failure shall constitute an Event of Default); or

(b) the failure of the Owner Trustee to pay when due any payment of Original Amount of, interest on, Make-Whole Amount, if any, or other amount due and payable under any Equipment Note or hereunder (other than as a result of a Lease Event of Default or a Lease Default) and such failure shall have continued unremedied for ten Business Days in the case of any payment of Original Amount or interest or Make-Whole Amount, if any, thereon and, in the case of any other amount, for ten Business Days after the Owner Trustee or the Owner Participant receives written demand from the Mortgagee or any Note Holder; or

(c) any Lien required to be discharged by the Owner Trustee, in its individual capacity pursuant to Section 4.01(b) hereof or in its individual or trust capacity pursuant to Section 7.3.1 of the Participation Agreement, or by the Owner Participant pursuant to Section 7.2.1 of the Participation Agreement shall remain undischarged for a period of 30 days after the Owner Trustee or the Owner Participant, as the case may be, shall have received written notice from the Mortgagee or any Note Holder of such Lien; or


-36-

(d) any representation or warranty made by the Owner Participant or the Owner Trustee in the Participation Agreement or this Trust Indenture or in any certificate furnished by the Owner Participant or the Owner Trustee to the Mortgagee or any Note Holder in connection with the transactions contemplated by the Operative Agreements shall prove to have been false or incorrect when made in any material respect and continues to be material and adverse to the interests of the Mortgagee or the Note Holders; and if such misrepresentation is capable of being corrected and if such correction is being sought diligently, such misrepresentation shall not have been corrected within 60 days (or, without affecting Section 4.02(f) hereof, in the case of the representation made in
Section 6.3.6 or 6.2.6 of the Participation Agreement as to citizenship of the Owner Trustee in its individual capacity or of the Owner Participant, respectively, as soon as is reasonably practicable but in any event within 60 days) following notice thereof from the Mortgagee or any Note Holder to the Owner Trustee or the Owner Participant, as the case may be; or

(e) other than as provided in (c) above or (f) below, any failure by the Owner Trustee or Owner Participant to observe or perform any other covenant or obligation of the Owner Trustee or Owner Participant, as the case may be, for the benefit of the Mortgagee or the Note Holders contained in the Participation Agreement, Section 4.2.1 of the Trust Agreement, the Equipment Notes or this Trust Indenture which is not remedied within a period of 60 days after notice thereof has been given to the Owner Trustee and the Owner Participant; or

(f) if at any time when the Aircraft is registered under the Laws of the United States, the Owner Participant shall not be a "citizen of the United States" within the meaning of Section 40102(a)(15) of Part A of Subtitle VII of Title 49, United States Code, and as the result thereof the registration of the Aircraft under the Federal Aviation Act, and regulations then applicable thereunder, shall cease to be effective; provided that no Event of Default shall be deemed to have occurred under this paragraph (f) unless such circumstances continue unremedied for more than 30 days after the Owner Participant has Actual Knowledge of the state of facts that resulted in such ineffectiveness and of such loss of citizenship; or

(g) at any time either (i) the commencement of an involuntary case or other proceeding in respect of the Owner Participant, the Owner Trustee, the Trust or the Trust Estate under the federal bankruptcy Laws, as now constituted or hereafter amended, or any other applicable federal or state bankruptcy, insolvency or other similar Law in the United States or seeking the appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of the Owner Participant, the Owner Trustee, the Trust or the Trust Estate or for all or substantially all of its property, or seeking the winding-up or liquidation of its affairs and the continuation of any such case or other proceeding undismissed and unstayed for a period of 60 consecutive days; or (ii) the commencement by the Owner Participant, the Owner Trustee, the Trust or the Trust Estate of a voluntary case or proceeding under the federal


-37-

bankruptcy Laws, as now constituted or hereafter amended, or any other applicable federal or state bankruptcy, insolvency or other similar Law in the United States, or the consent by the Owner Participant, the Owner Trustee, the Trust or the Trust Estate to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of the Owner Participant, the Owner Trustee, the Trust or the Trust Estate or for all or substantially all of its property, or the making by the Owner Participant, the Owner Trustee, the Trust or the Trust Estate of any assignment for the benefit of creditors or the Owner Participant or the Owner Trustee shall take any action to authorize any of the foregoing; provided, however, that an event referred to in this Section 4.02(g) with respect to the Owner Participant shall not constitute an Event of Default if within 30 days of the commencement of the case or proceeding a final non-appealable order, judgment or decree shall be entered in such case or proceeding by a court or a trustee, custodian, receiver or liquidator, to the effect that, no part of the Trust Estate (except for the Owner Participant's beneficial interest therein) and no right, title or interest under the Trust Indenture Estate shall be included in, or be subject to, any declaration or adjudication of, or proceedings with respect to, the bankruptcy, insolvency or liquidation of the Owner Participant referred to in this Section 4.02(g).

SECTION 4.03. CERTAIN RIGHTS

The Mortgagee shall give the Note Holders, the Owner Trustee and the Owner Participant prompt written notice of any Event of Default of which the Mortgagee has Actual Knowledge and shall give the Note Holders, the Owner Trustee and the Owner Participant not less than ten Business Days prior written notice of the date (the "Enforcement Date") on or after which the Mortgagee may, subject to the limitation set forth in Section 4.04(a), commence and consummate the exercise of any remedy or remedies described in Section 4.04, 4.05 or 4.06 hereof; provided, however, that in the event the Mortgagee shall have validly terminated the Lease, the Mortgagee shall not sell or lease, or otherwise afford the use of, the Aircraft or any portion thereof to the Lessee or any Affiliate thereof. Without limiting the generality of the foregoing, the Mortgagee shall give the Owner Trustee, the Owner Participant and the Lessee at least ten Business Days prior written notice (which may be given concurrently with notice of the Enforcement Date) of any declaration of the Lease to be in default pursuant to Sections 14 and 15 of the Lease or any termination of the Lease or of the exercise of any remedy or remedies pursuant to Section 15 of the Lease. If an Event of Default shall have occurred and be continuing, the Owner Trustee shall have the rights set forth below, any of which may be exercised directly by the Owner Participant.

If as a result of the occurrence of an Event of Default in respect of the nonpayment by Lessee of Basic Rent due under the Lease, the Mortgagee shall have insufficient funds to make any payment of Original Amount and interest on any Equipment Note on the day it becomes due and payable, the Owner Trustee may, but shall not be obligated to pay the Mortgagee prior to the Enforcement Date, in the manner provided in Section 2.04 hereof, for


-38-

application in accordance with Section 3.01 hereof, an amount equal to the portion of the Original Amount and interest (including interest, if any, on any overdue payments of such portion of Original Amount and interest) then due and payable on the Equipment Notes, and, unless the Owner Trustee has cured Events of Default in respect of payments of Basic Rent on each of the three immediately preceding Basic Rent payment dates, or the Owner Trustee has cured six previous Events of Default in respect of payments of Basic Rent, such payment by the Owner Trustee shall, solely for purposes of this Trust Indenture be deemed to cure any Event of Default which would otherwise have arisen on account of the nonpayment by Lessee of such installment of Basic Rent (but not any other Default or Event of Default which shall have occurred and be continuing).

If any Event of Default (other than in respect of the nonpayment of Basic Rent by the Lessee) which can be cured by the payment of money has occurred, the Owner Trustee may, but shall not be obligated to, cure such Event of Default by making such payment prior to the Enforcement Date as is necessary to accomplish the observance or performance of the defaulted covenant, condition or agreement to the party entitled to the same.

Except as hereinafter in this Section 4.03 provided, the Owner Trustee shall not, as a result of exercising the right to cure any such Event of Default, obtain any Lien on any of the Mortgaged Property or any Rent payable under the Lease for or on account of costs or expenses incurred in connection with the exercise of such right, nor shall any claim of the Owner Trustee against Lessee or any other party for the repayment of such costs or expenses impair the prior right and security interest of the Mortgagee in and to the Mortgaged Property. Upon any payment by the Owner Trustee pursuant to the first or second preceding paragraphs of this Section 4.03, the Owner Trustee shall be subrogated to the rights of the Mortgagee and the Note Holders in respect of the Basic Rent which was overdue at the time of such payment and interest payable by the Lessee on account of its being overdue and any Supplemental Rent in respect of the reimbursement of amounts paid by Owner Trustee pursuant to the immediately preceding paragraph (but in either case shall have no rights as a secured party hereunder), and thereafter, the Owner Trustee shall be entitled (so long as the application thereof shall not give rise to an Event of Default hereunder) to receive such overdue Basic Rent or Supplemental Rent, as the case may be, and interest thereon upon receipt thereof by the Mortgagee; provided, however, that (i) if the Original Amount and interest on the Equipment Notes shall have become due and payable pursuant to Section 4.04(b) hereof, such subrogation shall, until the Secured Obligations shall have been paid in full, be subordinate to the rights of the Mortgagee, the Note Holders and the Indenture Indemnitees in respect of such payment of overdue Basic Rent, Supplemental Rent and such interest and (ii) the Owner Trustee shall not otherwise attempt to recover any such amount paid by it on behalf of the Lessee pursuant to this Section 4.03 except by demanding of the Lessee payment of such amount, or by commencing an action at law against the Lessee and obtaining and enforcing a


-39-

judgment against the Lessee for the payment of such amount or taking appropriate action in a pending action at law against the Lessee (provided, that at no time while an Event of Default shall have occurred and be continuing shall any such demand be made or shall any such action be commenced (or continued) and any amounts nevertheless received by the Owner Trustee in respect thereof shall be held in trust for the benefit of, and promptly paid to, the Mortgagee for distribution as provided in Section 3.03 hereof).

Neither the Owner Trustee nor the Owner Participant shall have the right to cure any Lease Event of Default or Lease Default except as specified in this Section 4.03.

SECTION 4.04. REMEDIES

(a) If an Event of Default shall have occurred and be continuing and so long as the same shall continue unremedied, then and in every such case the Mortgagee may, subject to the second and third paragraphs of this Section 4.04(a), exercise any or all of the rights and powers and pursue any and all of the remedies pursuant to this Article IV and shall have and may exercise all of the rights and remedies of a secured party under the Uniform Commercial Code and, in the event such Event of Default is also a Lease Event of Default, any and all of the remedies pursuant to Section 15 of the Lease and may take possession of all or any part of the properties covered or intended to be covered by the Lien created hereby or pursuant hereto and may exclude the Owner Participant, the Owner Trustee and Lessee and all persons claiming under any of them wholly or partly therefrom; provided, that the Mortgagee shall give the Owner Trustee and the Owner Participant 20 days prior written notice of its intention to sell the Aircraft, and provided, further, that in the event the Mortgagee shall have validly terminated the Lease, the Mortgagee shall not sell or lease, or otherwise afford the use of, the Aircraft or any portion thereof to the Lessee or any Affiliate thereof. Unless an Event of Default not resulting from or relating to a Lease Event of Default has occurred and is continuing, the Owner Participant may bid at the sale and become the purchaser. Without limiting any of the foregoing, it is understood and agreed that the Mortgagee may exercise any right of sale of the Aircraft available to it, even though it shall not have taken possession of the Aircraft and shall not have possession thereof at the time of such sale.

Anything in this Trust Indenture to the contrary notwithstanding, if the Event of Default arises solely by reason of one or more circumstances which constitutes a Lease Event of Default, the Mortgagee shall not be entitled to exercise any remedy hereunder unless the Mortgagee as security assignee of the Owner Trustee shall have exercised or concurrently be exercising one or more of the dispossessory remedies provided for in Section 15 of the Lease with respect to the Aircraft; provided, however, that such requirement to exercise one or more of such remedies under the Lease shall not apply in circumstances where the Mortgagee is, and has been, for a continuous period in excess of 60 days or such other period as may be specified in Section 1110(a)(1)(A) of the Bankruptcy Code (such 60-day or other period being


-40-

the "New Section 1110 Period"), involuntarily stayed or prohibited by applicable law or court order from exercising such remedies under the Lease (a "Continuous Stay Period"); provided further, however, that the requirement to exercise one or more of such remedies under the Lease shall nonetheless be applicable during a Continuous Stay Period subsequent to the expiration of the New Section 1110 Period to the extent that the continuation of such Continuous Stay Period subsequent to the expiration of the New Section 1110 Period (A) results from an agreement by the trustee or the debtor-in-possession in such proceeding during the New Section 1110 Period with the approval of the relevant court to perform the Lease in accordance with Section 1110(a)(1)(A) of the Bankruptcy Code and continues to perform as required by Section 1110(a)(1)(A-B) of the Bankruptcy Code or (B) is an extension of the New Section 1110 Period with the consent of the Mortgagee pursuant to Section 1110(b) of the Bankruptcy Code or (C) results from the Lessee's assumption during the New Section 1110 Period with the approval of the relevant court of the Lease pursuant to Section 365 of the Bankruptcy Code and Lessee's continuous performance of the Lease as so assumed or (D) is the consequence of the Mortgagee's own failure to give any requisite notice to any person. In the event that the applicability of Section 1110 of the Bankruptcy Code to the Aircraft is being contested by Lessee in judicial proceedings, both of the Mortgagee and the Owner Trustee shall have the right to participate in such proceedings; provided that any such participation by the Owner Trustee shall not affect in any way any rights or remedy of the Mortgagee hereunder.

It is expressly understood and agreed that, subject only to the two preceding paragraphs, the inability, described in such paragraphs, of the Mortgagee to exercise any right or remedy under the Lease shall in no event and under no circumstances prevent the Mortgagee from exercising any or all of its rights, powers and remedies under this Trust Indenture, including, without limitation, this Article IV.

(b) If an Event of Default shall have occurred and be continuing, then and in every such case the Mortgagee may (and shall, upon receipt of a written demand therefor from a Majority in Interest of Note Holders), subject to Section 4.03 hereof, at any time, by delivery of written notice or notices to the Owner Trustee and the Owner Participant, declare all the Equipment Notes to be due and payable, whereupon the unpaid Original Amount of all Equipment Notes then outstanding, together with accrued but unpaid interest thereon (without Make-Whole Amount) and other amounts due thereunder, shall immediately become due and payable without presentment, demand, protest or notice, all of which are hereby waived; provided that if an Event of Default referred to in clause (g) of
Section 4.02 hereof shall have occurred or a Lease Event of Default under
Section 14.5 of the Lease shall have occurred, then and in every such case the unpaid Original Amount then outstanding, together with accrued but unpaid interest and all other amounts due thereunder and hereunder shall immediately and without further act become due and payable without presentment, demand, protest or notice, all of which are hereby waived; provided further that in the event of a reorganization


-41-

proceeding involving the Lessee instituted under Chapter 11 of the Bankruptcy Code, if no Lease Event of Default (including any Lease Event of Default set forth in Section 14.3 of the Lease) and no other Event of Default (other than the failure to pay the Original Amount of the Equipment Notes which by such declaration shall have become payable) exists at any time after the consummation of such proceeding, such declaration shall be automatically rescinded without any further action on the part of any Note Holder.

This Section 4.04(b), however, is subject to the condition that, if at any time after the Original Amount of the Equipment Notes shall have become so due and payable, and before any judgment or decree for the payment of the money so due, or any thereof, shall be entered, all overdue payments of interest upon the Equipment Notes and all other amounts payable under the Equipment Notes (except the Original Amount of the Equipment Notes which by such declaration shall have become payable) shall have been duly paid, and every other Default and Event of Default with respect to any covenant or provision of this Trust Indenture shall have been cured, then and in every such case a Majority in Interest of Note Holders may (but shall not be obligated to), by written instrument filed with the Mortgagee, rescind and annul the Mortgagee's declaration (or such automatic acceleration) and its consequences; but no such rescission or annulment shall extend to or affect any subsequent Default or Event of Default or impair any right consequent thereon.

Any acceleration pursuant to this Section 4.04(b) shall be automatically rescinded and any related declaration of an Event of Default annulled in the event that the Owner Trustee shall have cured, in accordance with Section 4.03 hereof, the Event of Default that resulted in such acceleration or declaration.

(c) The Note Holders shall be entitled, at any sale pursuant to Section 15 of the Lease or this Section 4.04, to credit against any purchase price bid at such sale by such holder all or any part of the unpaid obligations owing to such Note Holder and secured by the Lien of this Trust Indenture (but only to the extent that such purchase price would have been paid to such Note Holder pursuant to Article III hereof if such purchase price were paid in cash and the foregoing provisions of this subsection (c) were not given effect).

(d) In the event of any sale of the Trust Indenture Estate, or any part thereof, pursuant to any judgment or decree of any court or otherwise in connection with the enforcement of any of the terms of this Trust Indenture, the unpaid Original Amount of all Equipment Notes then outstanding, together with accrued interest thereon (without Make-Whole Amount), and other amounts due thereunder, shall immediately become due and payable without presentment, demand, protest or notice, all of which are hereby waived.

(e) Notwithstanding anything contained herein, so long as the Pass Through Trustee under any Pass Through Trust Agreement (or its designee) is a Note Holder, the


-42-

Mortgagee will not be authorized or empowered to acquire title to any Mortgaged Property or take any action with respect to any Mortgaged Property so acquired by it if such acquisition or action would cause any Trust to fail to qualify as a "grantor trust" for federal income tax purposes.

SECTION 4.05. RETURN OF AIRCRAFT, ETC.

(a) If an Event of Default shall have occurred and be continuing and the Equipment Notes have been accelerated, subject to Section 4.03 hereof and unless the Owner Trustee or the Owner Participant shall have elected to purchase the Equipment Notes, at the request of the Mortgagee, the Owner Trustee shall promptly execute and deliver to the Mortgagee such instruments of title and other documents as the Mortgagee may deem necessary or advisable to enable the Mortgagee or an agent or representative designated by the Mortgagee, at such time or times and place or places as the Mortgagee may specify, to obtain possession of all or any part of the Mortgaged Property included in the Trust Indenture Estate to which the Mortgagee shall at the time be entitled hereunder. If the Owner Trustee shall for any reason fail to execute and deliver such instruments and documents after such request by the Mortgagee, the Mortgagee may
(i) obtain a judgment conferring on the Mortgagee the right to immediate possession and requiring the Owner Trustee to execute and deliver such instruments and documents to the Mortgagee, to the entry of which judgment the Owner Trustee hereby specifically consents to the fullest extent permitted by Law, and (ii) pursue all or part of such Mortgaged Property wherever it may be found and, in the event that a Lease Event of Default has occurred and is continuing, may enter any of the premises of Lessee wherever such Mortgaged Property may be or be supposed to be and search for such Mortgaged Property and take possession of and remove such Mortgaged Property. All expenses of obtaining such judgment or of pursuing, searching for and taking such property shall, until paid, be secured by the Lien of this Trust Indenture.

(b) Upon every such taking of possession, the Mortgagee may, from time to time, at the expense of the Mortgaged Property, make all such expenditures for maintenance, use, operation, storage, insurance, leasing, control, management, disposition, modifications or alterations to and of the Mortgaged Property, as it may deem proper. In each such case, the Mortgagee shall have the right to maintain, use, operate, store, insure, lease, control, manage, dispose of, modify or alter the Mortgaged Property and to carry on the business and to exercise all rights and powers of the Owner Participant and the Owner Trustee relating to the Mortgaged Property, as the Mortgagee shall deem best, including the right to enter into any and all such agreements with respect to the maintenance, use, operation, storage, insurance, leasing, control, management, disposition, modification or alteration of the Mortgaged Property or any part thereof as the Mortgagee may determine, and the Mortgagee shall be entitled to collect and receive directly all tolls, rents (including Rent), revenues, issues, income, products and profits of the Mortgaged Property and every part thereof, except Excluded Payments,


-43-

without prejudice, however, to the right of the Mortgagee under any provision of this Trust Indenture to collect and receive all cash held by, or required to be deposited with, the Mortgagee hereunder other than Excluded Payments. Such tolls, rents (including Rent), revenues, issues, income, products and profits shall be applied to pay the expenses of the maintenance, use, operation, storage, insurance, leasing, control, management, disposition, improvement, modification or alteration of the Mortgaged Property and of conducting the business thereof, and to make all payments which the Mortgagee may be required or may elect to make, if any, for taxes, assessments, insurance or other proper charges upon the Mortgaged Property or any part thereof (including the employment of engineers and accountants to examine, inspect and make reports upon the properties and books and records of the Owner Trustee), and all other payments which the Mortgagee may be required or authorized to make under any provision of this Trust Indenture, as well as just and reasonable compensation for the services of the Mortgagee, and of all persons properly engaged and employed by the Mortgagee with respect hereto.

SECTION 4.06. REMEDIES CUMULATIVE

Each and every right, power and remedy given to the Mortgagee specifically or otherwise in this Trust Indenture shall be cumulative and shall be in addition to every other right, power and remedy herein specifically given or now or hereafter existing at Law, in equity or by statute, and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time and as often and in such order as may be deemed expedient by the Mortgagee, and the exercise or the beginning of the exercise of any power or remedy shall not be construed to be a waiver of the right to exercise at the same time or thereafter any other right, power or remedy. No delay or omission by the Mortgagee in the exercise of any right, remedy or power or in the pursuance of any remedy shall impair any such right, power or remedy or be construed to be a waiver of any default on the part of the Owner Trustee or Lessee or to be an acquiescence therein.

SECTION 4.07. DISCONTINUANCE OF PROCEEDINGS

In case the Mortgagee shall have instituted any proceeding to enforce any right, power or remedy under this Trust Indenture by foreclosure, entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Mortgagee, then and in every such case the Owner Trustee, the Mortgagee and Lessee shall, subject to any determination in such proceedings, be restored to their former positions and rights hereunder with respect to the Mortgaged Property, and all rights, remedies and powers of the Owner Trustee, the Mortgagee or Lessee shall continue as if no such proceedings had been instituted.


-44-

SECTION 4.08. WAIVER OF PAST DEFAULTS

Upon written instruction from a Majority in Interest of Note Holders, the Mortgagee shall waive any past Default hereunder and its consequences and upon any such waiver such Default shall cease to exist and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Trust Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon; provided, that in the absence of written instructions from all the Note Holders, the Mortgagee shall not waive any Default (i) in the payment of the Original Amount, Make-Whole Amount, if any, and interest and other amounts due under any Equipment Note then outstanding, or (ii) in respect of a covenant or provision hereof which, under Article IX hereof, cannot be modified or amended without the consent of each Note Holder.

SECTION 4.09. APPOINTMENT OF RECEIVER

The Mortgagee shall, as a matter of right, be entitled to the appointment of a receiver (who may be the Mortgagee or any successor or nominee thereof) for all or any part of the Mortgaged Property, whether such receivership be incidental to a proposed sale of the Mortgaged Property or the taking of possession thereof or otherwise, and the Owner Trustee hereby consents to the appointment of such a receiver and will not oppose any such appointment. Any receiver appointed for all or any part of the Mortgaged Property shall be entitled to exercise all the rights and powers of the Mortgagee with respect to the Mortgaged Property.

SECTION 4.10. MORTGAGEE AUTHORIZED TO EXECUTE BILLS OF SALE, ETC.

Subject to the provisions of this Trust Indenture, the Owner Trustee irrevocably appoints the Mortgagee the true and lawful attorney-in-fact of the Owner Trustee (which appointment is coupled with an interest) in its name and stead and on its behalf, for the purpose of effectuating any sale, assignment, transfer or delivery for the enforcement of the Lien of this Trust Indenture, whether pursuant to foreclosure or power of sale, assignments and other instruments as may be necessary or appropriate, with full power of substitution, the Owner Trustee hereby ratifying and confirming all that such attorney or any substitute shall do by virtue hereof in accordance with applicable law. Nevertheless, if so requested by the Mortgagee or any purchaser, the Owner Trustee shall ratify and confirm any such sale, assignment, transfer or delivery, by executing and delivering to the Mortgagee or such purchaser all bills of sale, assignments, releases and other proper instruments to effect such ratification and confirmation as may be designated in any such request.


-45-

SECTION 4.11. RIGHTS OF NOTE HOLDERS TO RECEIVE PAYMENT

Notwithstanding any other provision of this Trust Indenture, the right of any Note Holder to receive payment of principal of, and premium, if any, and interest on an Equipment Note on or after the respective due dates expressed in such Equipment Note, or to bring suit for the enforcement of any such payment on or after such respective dates in accordance with the terms hereof, shall not be impaired or affected without the consent of such Note Holder.

ARTICLE V

DUTIES OF THE MORTGAGEE

SECTION 5.01. NOTICE OF EVENT OF DEFAULT

If the Mortgagee shall have Actual Knowledge of an Event of Default or of a Default arising from a failure to pay Rent, the Mortgagee shall give prompt written notice thereof to the Owner Trustee, the Owner Participant, Lessee, and each Note Holder. Subject to the terms of Sections 2.13, 4.03, 4.04, 4.08, 5.02 and 5.03 hereof, the Mortgagee shall take such action, or refrain from taking such action, with respect to such Event of Default or Default (including with respect to the exercise of any rights or remedies hereunder) as the Mortgagee shall be instructed in writing by a Majority in Interest of Note Holders. Subject to the provisions of Section 5.03, if the Mortgagee shall not have received instructions as above provided within 20 days after mailing notice of such Event of Default to the Note Holders, the Mortgagee may, subject to instructions thereafter received pursuant to the preceding provisions of this
Section 5.01, take such action, or refrain from taking such action, but shall be under no duty to take or refrain from taking any action, with respect to such Event of Default or Default as it shall determine advisable in the best interests of the Note Holders; provided, however, that the Mortgagee may not sell the Aircraft or any Engine without the consent of a Majority in Interest of Note Holders. For all purposes of this Trust Indenture, in the absence of Actual Knowledge on the part of the Mortgagee, the Owner Trustee or the Owner Participant, the Mortgagee, the Owner Trustee or the Owner Participant, as the case may be, shall not be deemed to have knowledge of a Default or an Event of Default (except, in the case of the Mortgagee, the failure of Lessee to pay any installment of Basic Rent within one Business Day after the same shall become due, if any portion of such installment was then required to be paid to the Mortgagee, which failure shall constitute knowledge of a Default) unless notified in writing by Lessee, the Owner Trustee, the Owner Participant or one or more Note Holders.

SECTION 5.03. INDEMNIFICATION

The Mortgagee shall not be required to take any action or refrain from taking any action under Section 5.01 (other than the first sentence thereof), 5.02 or Article IV hereof unless the Mortgagee shall have been indemnified to its reasonable satisfaction against any liability, cost or expense (including counsel fees) which may be incurred in connection therewith pursuant to a written agreement with one or more Note Holders.

SECTION 5.08. EFFECT OF REPLACEMENT

In the event of the substitution of an Airframe or of a Replacement Engine pursuant to Section 10 of the Lease, all provisions of this Trust Indenture relating to the Airframe or Engine or Engines being replaced shall be applicable to such Replacement Airframe or Replacement Engine or Engines with the same force and effect as if such Replacement Airframe or Replacement Engine or Engines were the same airframe or engine or engines, as the case may be, as the Airframe or Engine or Engines being replaced but for the Event of Loss with respect to the Airframe or Engine or Engines being replaced and the provisions of this Trust

Unless otherwise expressly provided in this Trust Indenture, any income realized as a result of any such investment, net of the Mortgagee's reasonable fees and expenses in making such investment, shall be held and applied by the Mortgagee in the same manner as the principal amount of such investment is to be applied and any losses, net of earnings and such reasonable fees and expenses, shall be charged against the principal amount invested. The Mortgagee shall not be liable for any loss resulting from any investment required to be made by it under this Trust Indenture other than by reason of its willful misconduct or gross negligence, and any such investment may be sold (without regard to its maturity) by the Mortgagee without instructions whenever such sale is necessary to make a distribution required by this Trust Indenture.

Without limiting the foregoing, the Mortgagee agrees that, prior to seeking indemnification from the Trust Indenture Estate, it will demand, and diligently pursue in good faith (but with no duty to exhaust all legal remedies therefor), indemnification available to the Mortgagee from Lessee under the Lease or the Participation Agreement.

ARTICLE VIII

SUCCESSOR AND SEPARATE TRUSTEES

SECTION 8.01. NOTICE OF SUCCESSOR OWNER TRUSTEE

In the case of any appointment of a successor to the Owner Trustee pursuant to the Trust Agreement including upon any merger, conversion, consolidation or sale of substantially all of the corporate trust business of the Owner Trustee pursuant to the Trust Agreement, the successor Owner Trustee shall give prompt written notice thereof to the Mortgagee, Lessee and the Note Holders.

SECTION 8.02. RESIGNATION OF MORTGAGEE; APPOINTMENT OF SUCCESSOR

(a) The Mortgagee or any successor thereto may resign at any time without cause by giving at least 30 days prior written notice to Lessee, the Owner Trustee, the Owner Participant and each Note Holder, such resignation to be effective upon the acceptance of the trusteeship by a successor Mortgagee. In addition, a Majority in Interest of Note Holders may at any time (but only with the consent of the Lessee, which consent shall not be unreasonably withheld, except that such consent shall not be necessary if a Lease Event of Default is continuing) remove the Mortgagee without cause by an instrument in writing delivered to the Owner Trustee, Lessee, the Owner Participant and the Mortgagee, and the Mortgagee shall promptly notify each Note Holder thereof in writing, such removal to be effective upon the acceptance of the trusteeship by a successor Mortgagee. In the case of the resignation or removal of the Mortgagee, a Majority in Interest of Note Holders may appoint a successor Mortgagee by an instrument signed by such holders, which successor, so long as no Lease Event of Default shall have occurred and be continuing, shall be subject to Lessee's reasonable approval. If a successor Mortgagee shall not have been appointed within 30 days after such notice of resignation or removal, the Mortgagee, the Owner Trustee, the Owner Participant or


-57-

any Note Holder may apply to any court of competent jurisdiction to appoint a successor Mortgagee to act until such time, if any, as a successor shall have been appointed as above provided. The successor Mortgagee so appointed by such court shall immediately and without further act be superseded by any successor Mortgagee appointed as above provided.

(b) Any successor Mortgagee, however appointed, shall execute and deliver to the Owner Trustee, the predecessor Mortgagee and the Lessee an instrument accepting such appointment and assuming the obligations of the Mortgagee under the Participation Agreement arising from and after the time of such appointment, and thereupon such successor Mortgagee, without further act, shall become vested with all the estates, properties, rights, powers and duties of the predecessor Mortgagee hereunder in the trust hereunder applicable to it with like effect as if originally named the Mortgagee herein; but nevertheless upon the written request of such successor Mortgagee, such predecessor Mortgagee shall execute and deliver an instrument transferring to such successor Mortgagee, upon the trusts herein expressed applicable to it, all the estates, properties, rights and powers of such predecessor Mortgagee, and such predecessor Mortgagee shall duly assign, transfer, deliver and pay over to such successor Mortgagee all monies or other property then held by such predecessor Mortgagee hereunder.

(c) Any successor Mortgagee, however appointed, shall be a bank or trust company having its principal place of business in the Borough of Manhattan, City and State of New York; Chicago, Illinois; Hartford, Connecticut; Wilmington, Delaware; or Boston, Massachusetts and having (or whose obligations under the Operative Agreements are guaranteed by an affiliated entity having) a combined capital and surplus of at least $100,000,000, if there be such an institution willing, able and legally qualified to perform the duties of the Mortgagee hereunder upon reasonable or customary terms.

(d) Any corporation into which the Mortgagee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Mortgagee shall be a party, or any corporation to which substantially all the corporate trust business of the Mortgagee may be transferred, shall, subject to the terms of paragraph (c) of this Section 8.02, be a successor Mortgagee and the Mortgagee under this Trust Indenture without further act.

SECTION 8.03. APPOINTMENT OF ADDITIONAL AND SEPARATE TRUSTEES

(a) Whenever (i) the Mortgagee shall deem it necessary or desirable in order to conform to any Law of any jurisdiction in which all or any part of the Trust Indenture Estate shall be situated or to make any claim or bring any suit with respect to or in connection with the Trust Indenture Estate, this Trust Indenture, any other Indenture Agreement, the Equipment


-58-

Notes or any of the transactions contemplated by the Participation Agreement,
(ii) the Mortgagee shall be advised by counsel satisfactory to it that it is so necessary or prudent in the interests of the Note Holders (and the Mortgagee shall so advise the Owner Trustee and Lessee), or (iii) the Mortgagee shall have been requested to do so by a Majority in Interest of Note Holders, then in any such case, the Mortgagee and, upon the written request of the Mortgagee, the Owner Trustee, shall execute and deliver an indenture supplemental hereto and such other instruments as may from time to time be necessary or advisable either
(1) to constitute one or more bank or trust companies or one or more persons approved by the Mortgagee, either to act jointly with the Mortgagee as additional trustee or trustees of all or any part of the Trust Indenture Estate, or to act as separate trustee or trustees of all or any part of the Trust Indenture Estate, in each case with such rights, powers, duties and obligations consistent with this Trust Indenture as may be provided in such supplemental indenture or other instruments as the Mortgagee or a Majority in Interest of Note Holders may deem necessary or advisable, or (2) to clarify, add to or subtract from the rights, powers, duties and obligations theretofore granted any such additional or separate trustee, subject in each case to the remaining provisions of this Section 8.03. If the Owner Trustee shall not have taken any action requested of it under this Section 8.03(a) that is permitted or required by its terms within 15 days after the receipt of a written request from the Mortgagee so to do, or if an Event of Default shall have occurred and be continuing, the Mortgagee may act under the foregoing provisions of this Section 8.03(a) without the concurrence of the Owner Trustee, and the Owner Trustee hereby irrevocably appoints (which appointment is coupled with an interest) the Mortgagee, its agent and attorney-in-fact to act for it under the foregoing provisions of this Section 8.03(a) in either of such contingencies. The Mortgagee may, in such capacity, execute, deliver and perform any such supplemental indenture, or any such instrument, as may be required for the appointment of any such additional or separate trustee or for the clarification of, addition to or subtraction from the rights, powers, duties or obligations theretofore granted to any such additional or separate trustee. In case any additional or separate trustee appointed under this Section 8.03(a) shall die, become incapable of acting, resign or be removed, all the assets, property, rights, powers, trusts, duties and obligations of such additional or separate trustee shall revert to the Mortgagee until a successor additional or separate trustee is appointed as provided in this Section 8.03(a).

All other rights, powers, duties and obligations conferred or imposed upon any additional or separate trustee shall be exercised or performed by the Mortgagee and such additional or separate trustee jointly except to the extent that applicable Law of any jurisdiction in which any


-59-

particular act is to be performed renders the Mortgagee incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations (including the holding of title to all or part of the Trust Indenture Estate in any such jurisdiction) shall be exercised and performed by such additional or separate trustee. No additional or separate trustee shall take any discretionary action except on the instructions of the Mortgagee or a Majority in Interest of Note Holders. No trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder, except that the Mortgagee shall be liable for the consequences of its lack of reasonable care in selecting, and the Mortgagee's own actions in acting with, any additional or separate trustee. Each additional or separate trustee appointed pursuant to this Section 8.03 shall be subject to, and shall have the benefit of Articles IV through VIII and Article X hereof insofar as they apply to the Mortgagee. The powers of any additional or separate trustee appointed pursuant to this Section 8.03 shall not in any case exceed those of the Mortgagee hereunder.

(c) If at any time the Trustee shall deem it no longer necessary or desirable or in order to conform to any such Law or take any such action or shall be advised by such counsel that it is no longer so necessary or desirable in the interest of the Note Holders, or in the event that the Mortgagee shall have been requested to do so in writing by a Majority in Interest of Note Holders, the Mortgagee and, upon the written request of the Mortgagee, the Owner Trustee, shall execute and deliver an indenture supplemental hereto and all other instruments and agreements necessary or proper to remove any additional or separate trustee. The Mortgagee may act on behalf of the Owner Trustee under this Section 8.03(c) when and to the extent it could so act under Section 8.03(a) hereof.

Owner Participant hereby agrees, whether or not any of the transactions contemplated hereby shall be consummated, to assume liability for, and hereby indemnifies, protects, saves and keeps harmless, First Security and its successors, assigns, agents and servants, from and against any and all liabilities, obligations, losses, damages, penalties, taxes (excluding any Taxes which are not required to be indemnified by Lessee pursuant to Section 9.1 or 9.3 of the Participation Agreement and excluding any taxes payable by First Security on or measured by any compensation received by First Security for its services under this Trust Agreement), claims, actions, suits, costs, expenses or disbursements (including, without limitation, reasonable legal fees and expenses, but excluding internal costs and expenses such as salaries and overhead, and including, without limitation, any liability of an owner, any strict liability and any liability without fault) of any kind and nature whatsoever which may be imposed on, incurred by or asserted against First Security (whether or not also indemnified against by Lessee under the Lease or under the Participation Agreement or also indemnified against by any other Person; provided, that Owner Participant shall be subrogated to the rights of Owner Trustee against Lessee or any other indemnitor)


-15-

in any way relating to or arising out of this Trust Agreement or any of the other Operative Agreements or the enforcement of any of the terms of any thereof, or in any way relating to or arising out of the manufacture, purchase, acceptance, nonacceptance, rejection, ownership, delivery, lease, possession, use, operation, condition, sale, return or other disposition of the Aircraft (including, without limitation, latent and other defects, whether or not discoverable, and any claim for patent, trademark or copyright infringement), or in any way relating to or arising out of the administration of the Trust Estate or the action or inaction of Owner Trustee, under this Trust Agreement, except
(a) in the case of gross negligence or willful misconduct on the part of First Security, in its individual capacity or as Owner Trustee, in the performance or nonperformance of its duties under this Trust Agreement or under any of the other Owner Trustee Agreements or (b) those Expenses resulting from the inaccuracy of any representation or warranty of First Security (or from the failure of First Security to perform any of its covenants) in Section 6.3, in
Section 6.03 of the Trust Indenture, in Section 4 of the Lease, in Section 6.3 of the Participation Agreement or elsewhere in any of the Operative Agreements or (c) as may result from a breach by First Security of its covenant in the last sentence of Section 5.4.1 or (d) in the case of the failure to use ordinary care on the part of First Security, in its individual capacity or as Owner Trustee, in the receipt or disbursement of funds or in connection with its obligation to invest funds pursuant to Section 4 of the Participation Agreement, Section 4.4 of the Lease or Section 4.3 hereof or in compliance with the provisions of the first sentence of Section 6.8 or (e) any liability on the part of Owner Trustee arising out of its negligence or willful or negligent misconduct in connection with its obligations under Section 5.1, 6.8 or 9.2 hereof or Section 4.01 of the Trust Indenture, or (f) those Expenses arising under any circumstances or upon any terms where Lessee would not have been required to indemnify First Security pursuant to Section 9.1 or 9.3 of the Participation Agreement (disregarding for purposes of this Section 7(f), Sections 9.1.2(b) and 9.3.2(j) of the Participation Agreement); provided, that before asserting its right to indemnification, if any, pursuant to this Section 7, First Security shall first demand its corresponding right to indemnification pursuant to Section 9 of the Participation Agreement (but need not exhaust any or all remedies available thereunder). The indemnities contained in this Section 7 extend to First Security only in its individual capacity and shall not be construed as indemnities of the Trust Indenture Estate or the Trust Estate (except to the extent, if any, that First Security has been reimbursed by the Trust


-16-

Indenture Estate or the Trust Estate for amounts covered by the indemnities contained in this Section 7). The indemnities contained in this Section 7 shall survive the termination of this Trust Agreement. In addition, if necessary, First Security shall be entitled to indemnification from the Trust Estate, subject to the Lien of the Trust Indenture, for any liability, obligation, loss, damage, penalty, tax, claim, action, suit, cost, expense or disbursement indemnified against pursuant to this Section 7 to the extent not reimbursed by Lessee, Owner Participant or others, but without releasing any of them from their respective agreements of reimbursement; and, to secure the same First Security shall have a lien on the Trust Estate, subject to the lien of the Trust Indenture and subject further to the provisions of Section 6.7, which shall be prior to any interest therein of Owner Participant. The payor of any indemnity under this Section 7 shall be subrogated to any right of the person indemnified in respect of the matter as to which such indemnity was paid.

SECTION 8. TRANSFER OF OWNER PARTICIPANT'S INTEREST

8.1 TRANSFER OF INTEREST

All provisions of Section 10 of the Participation Agreement applicable to a transfer by the Owner Participant shall (with the same force and effect as if set forth in full in this Section 8.1) be applicable to any assignment, conveyance or other transfer by Owner Participant of any of its right, title or interest in and to the Participation Agreement, the Trust Estate or this Trust Agreement. If there is more than one Owner Participant, no assignment, conveyance or other transfer by an Owner Participant of any of its right, title or interest in and to this Trust Agreement or the Trust Estate shall be valid unless each other Owner Participant's prior written consent (which consent may be withheld in the sole discretion of such other Owner Participant) is given to such assignment, conveyance or other transfer.

8.2 ACTIONS OF OWNER PARTICIPANTS

If at any time prior to the termination of this Trust Agreement there is more than one Owner Participant, then, subject to Section 11.5, during such time, if any action is required to be taken by all Owner Participants and whenever any direction, authorization, approval, consent, instruction or other action is permitted to be given or taken by Owner Participant, it shall be given or taken only upon unanimous agreement of all Owner Participants; provided, that the termination


-17-

of this Trust Agreement pursuant to Section 11.2 may be effected upon the election of any Owner Participant.

SECTION 9. SUCCESSOR OWNER TRUSTEES; CO-TRUSTEES

9.1 RESIGNATION OF OWNER TRUSTEE; APPOINTMENT OF SUCCESSOR

9.1.1 RESIGNATION OR REMOVAL

Owner Trustee or any successor Owner Trustee (a) shall resign if required to do so pursuant to Section 13.3 of the Participation Agreement or upon obtaining Actual Knowledge of any facts that would cast doubt upon its continuing status as a Citizen of the United States and (b) may resign at any time without cause by giving at least 60 days prior written notice to Owner Participant, Mortgagee and Lessee, such resignation to be effective upon the assumption of the trusts hereunder by the successor Owner Trustee under Section
9.1.2. In addition, Owner Participant may at any time remove Owner Trustee, with or without cause by a notice in writing delivered to Owner Trustee, Mortgagee and Lessee, such removal to be effective upon the assumption of the trusts hereunder by the successor Owner Trustee under Section 9.1.2, provided, that, in the case of a removal without cause, unless a Lease Event of Default shall have occurred and be continuing, such removal shall be subject to the consent of Lessee (which consent shall not be unreasonably withheld). In the case of the resignation or removal of Owner Trustee, Owner Participant may appoint a successor Owner Trustee by an instrument signed by Owner Participant, with, unless a Lease Event of Default shall have occurred and be continuing, the consent of Lessee (which consent shall not be unreasonably withheld). If a successor Owner Trustee shall not have been appointed within 30 days after such notice of resignation or removal, Owner Trustee, any Owner Participant, Lessee or Mortgagee may apply to any court of competent jurisdiction to appoint a successor Owner Trustee to act until such time, if any, as a successor shall have been appointed as above provided. Any successor Owner Trustee so appointed by such court shall immediately and without further act be superseded by any successor Owner Trustee appointed as above provided within one year from the date of the appointment by such court.


-18-

9.1.2 EXECUTION AND DELIVERY OF DOCUMENTS, ETC.

Any successor Owner Trustee, however appointed, shall execute and deliver to the predecessor Owner Trustee, with a copy to Owner Participant, Lessee and Mortgagee, an instrument accepting such appointment and assuming the obligations of Owner Trustee, in its individual capacity and as Owner Trustee, under the Owner Trustee Agreements, and thereupon such successor Owner Trustee, without further act, shall become vested with all the estates, properties, rights, powers, duties and trusts of the predecessor Owner Trustee in the trusts under this Trust Agreement with like effect as if originally named Owner Trustee in this Trust Agreement; but nevertheless, upon the written request of such successor Owner Trustee, such predecessor Owner Trustee shall execute and deliver an instrument transferring to such successor Owner Trustee, upon the trusts herein expressed, all the estates, properties, rights, powers and trusts of such predecessor Owner Trustee, and such predecessor Owner Trustee shall duly assign, transfer, deliver and pay over to such successor Owner Trustee all monies or other property then held by such predecessor Owner Trustee upon the trusts herein expressed. Upon the appointment of any successor Owner Trustee under this Section 9.1, the predecessor Owner Trustee will execute such documents as are provided to it by such successor Owner Trustee and will take such further actions as are requested of it by such successor Owner Trustee as are required to cause registration of the Aircraft included in the Trust Estate to be transferred upon the records of the FAA, or other governmental authority having jurisdiction, into the name of the successor Owner Trustee.

9.1.3 QUALIFICATIONS

Any successor Owner Trustee, however appointed, shall be a Citizen of the United States and shall also be a bank or trust company organized under the Laws of the United States or any state thereof having a combined capital and surplus of at least $100,000,000, if there be such an institution willing, able and legally qualified to perform the duties of Owner Trustee under this Trust Agreement upon reasonable or customary terms. No such successor Owner Trustee shall be located in a jurisdiction which creates material adverse consequences for Lessee (unless such material adverse consequences would be created by substantially all jurisdictions where major banking or trust institutions are located).


-19-

9.1.4 MERGER, ETC.

Any corporation into which First Security may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which First Security shall be a party, or any corporation to which substantially all the corporate trust business of First Security may be transferred, shall, subject to the terms of Section 9.1.3, be Owner Trustee under this Trust Agreement without further act, provided, that such corporation shall not also be the Mortgagee.

9.2 CO-TRUSTEES AND SEPARATE TRUSTEES

(a) If at any time it shall be necessary or prudent in order to conform to any Law of any jurisdiction in which all or any part of the Trust Estate is located, or Owner Trustee being advised by counsel shall determine that it is so necessary or prudent in the interest of Owner Participant or Owner Trustee, or Owner Trustee shall have been directed to do so by Owner Participant, Owner Trustee and Owner Participant shall execute and deliver an agreement supplemental hereto and all other instruments and agreements necessary or proper to constitute another bank or trust company or one or more persons (any or all of which shall be a Citizen of the United States) approved by Owner Trustee and Owner Participant, either to act as co-trustee, jointly with Owner Trustee, or to act as separate trustee under this Trust Agreement (any such co-trustee or separate trustee being herein sometimes referred to as an "additional trustee"). In the event Owner Participant shall not have joined in the execution of such agreements supplemental hereto within 10 days after the receipt of a written request from Owner Trustee so to do, or in case a Lease Event of Default or Event of Default shall occur and be continuing, Owner Trustee may act under the foregoing provisions of this Section 9.2 without the concurrence of Owner Participant; and Owner Participant hereby appoints Owner Trustee its agent and attorney-in-fact to act for it under the foregoing provisions of this Section 9.2 in either of such contingencies.

(b) Every additional trustee under this Trust Agreement shall, to the extent permitted by Law, be appointed and act, and Owner Trustee and its successors shall act, subject to the following provisions and conditions:

(i) All powers, duties, obligations and rights conferred upon Owner Trustee in respect of the custody, control and management of monies, the Aircraft or documents


-20-

authorized to be delivered under this Trust Agreement or under the Participation Agreement shall be exercised solely by Owner Trustee;

(ii) All other rights, powers, duties and obligations conferred or imposed upon Owner Trustee shall be conferred or imposed upon and exercised or performed by Owner Trustee and such additional trustee jointly, except to the extent that under any Law of any jurisdiction in which any particular act or acts are to be performed (including the holding of title to the Trust Estate) Owner Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations shall be exercised and performed by such additional trustee;

(iii) No power given to, or which it is provided hereby may be exercised by, any such additional trustee shall be exercised under this Trust Agreement by such additional trustee, except jointly with, or with the consent in writing of, Owner Trustee;

(iv) No trustee under this Trust Agreement shall be personally liable by reason of any action or omission of any other trustee under this Trust Agreement;

(v) Owner Participant, at any time, by an instrument in writing may remove any such additional trustee. In the event that Owner Participant shall not have joined in the execution of any such instrument within ten days after the receipt of a written request from Owner Trustee so to do, Owner Trustee shall have the power to remove any such additional trustee without the concurrence of Owner Participant; and Owner Participant hereby appoints Owner Trustee its agent and attorney-in-fact to act for it in such connection in such contingency; and

(vi) No appointment of, or action by, any additional trustee will relieve Owner Trustee of any of its obligations under, or otherwise affect any of the terms of, the Trust Indenture or affect the interests of Mortgagee or the Note Holders in the Trust Indenture Estate.

(c) In case any separate trustee under this Section 9.2 shall die, become incapable of acting, resign or be removed, the title to the Trust Estate and all rights and duties of such separate trustee shall, so far as permitted by


-21-

Law, vest in and be exercised by Owner Trustee, without the appointment of a successor to such separate trustee.

SECTION 10. SUPPLEMENTS AND AMENDMENTS TO TRUST AGREEMENT AND OTHER DOCUMENTS

10.1 SUPPLEMENTS AND AMENDMENTS AND DELIVERY THEREOF

Section 9 of the Participation Agreement or in the Tax Indemnity Agreement,

A signed copy of each amendment or supplement referred to in Section 10.1.1 to which Lessee is not a party shall be delivered promptly by Owner Trustee to Lessee, and a signed copy of each amendment or supplement referred to in Section 10.1.1 shall be delivered promptly by Owner Trustee to Mortgagee.

10.2 DISCRETION AS TO EXECUTION OF DOCUMENTS

Prior to executing any document required to be executed by it pursuant to the terms of Section 10.1, Owner Trustee shall be entitled to receive an opinion of its counsel to the effect that the execution of such document is authorized under this Trust Agreement. If in the opinion of Owner Trustee any such document adversely affects any right, duty, immunity or indemnity in favor of Owner Trustee under this Trust Agreement or under any other Owner Trustee Agreement, Owner Trustee may in its discretion decline to execute such document unless Owner Trustee is furnished with indemnification from Lessee or any other party upon terms and in amounts reasonably satisfactory to Owner Trustee to protect the Trust Estate and the Owner Trustee against any and all liabilities, costs and expenses arising out of the execution of such documents.

10.3 ABSENCE OF REQUIREMENTS AS TO FORM

It shall not be necessary for any written request furnished pursuant to Section 10.1 to specify the particular form of the proposed documents to be executed pursuant to such Section 10.1, but it shall be sufficient if such request shall indicate the substance thereof.

10.4 DISTRIBUTION OF DOCUMENTS

Promptly after the execution by Owner Trustee of any document entered into pursuant to Section 10.1, Owner Trustee shall mail, by certified mail, postage prepaid, a conformed copy thereof to Owner Participant, but the failure of Owner Trustee to mail such conformed copy shall not impair or affect the validity of such document.

10.5 NO REQUEST NEEDED AS TO LEASE SUPPLEMENT AND TRUST INDENTURE SUPPLEMENT

No written request pursuant to Section 10.1 shall be required to enable Owner Trustee to enter into, pursuant to Section 3.1 and the Lease or the Trust Indenture, as the case may be, the Lease Supplement with Lessee and the Trust Indenture Supplement.


-23-

SECTION 11. MISCELLANEOUS

11.1 TERMINATION OF TRUST AGREEMENT

This Trust Agreement and the trusts created hereby shall be of no further force or effect upon the earlier of (a) both the final discharge of the Trust Indenture pursuant to Section 10.01 thereof and the sale or other final disposition by Owner Trustee of all property constituting part of the Trust Estate and the final distribution by Owner Trustee of all monies or other property or proceeds constituting part of the Trust Estate in accordance with

Rockefeller living on the date of the earliest execution of this Trust Agreement by any party hereto, but if this Trust Agreement and the trusts created hereby shall be or become authorized under applicable Law to be valid for a period commencing on the 21st anniversary of the death of such last survivor (or, without limiting the generality of the foregoing, if legislation shall become effective providing for the validity of this Trust Agreement and the trusts created hereby for a period in gross exceeding the period for which this Trust Agreement and the trusts created hereby are hereinabove stated to extend and be valid), then this Trust Agreement and the trusts created hereby shall not terminate under this clause (b) but shall extend to and continue in effect, but only if such nontermination and extension shall then be valid under applicable Law, until the day preceding such date as the same shall, under applicable Law, cease to be valid; otherwise this Trust Agreement and the trusts created hereby shall continue in full force and effect in accordance with the terms hereof. Except as expressly set forth in
Section 11.2, this Trust Agreement and the trusts created hereby may not be revoked by Owner Participant.

11.2 TERMINATION AT OPTION OF THE OWNER PARTICIPANT

Notwithstanding Section 11.1 hereof, this Agreement and trust created hereby shall terminate and the Trust Estate shall be distributed to the Owner Participant, and this Agreement shall be of no further force and effect, upon the election of the Owner Participant by notice to the Owner Trustee, if such notice shall be accompanied by the written agreement (in form and substance satisfactory to the Owner Trustee) of the Owner Participant assuming all obligations of the Owner Trustee under or contemplated by the Operative Agreements or incurred


-24-

by it as trustee hereunder and releasing the Owner Trustee therefrom; provided, however, that such notice may be given only after the time the Lien of the Trust Indenture is discharged under Section 10.01 of the Trust Indenture and after the Lease shall no longer be in effect.

11.3 OWNER PARTICIPANT HAS NO LEGAL TITLE IN TRUST ESTATE

No Owner Participant shall have legal title to any part of the Trust Estate.

Any assignment, sale, transfer or other conveyance of the Aircraft by Owner Trustee made pursuant to the terms of this Trust Agreement or of the Lease or the Participation Agreement shall bind Owner Participant and shall be effective to transfer or convey all right, title and interest of Owner Trustee and Owner Participant in and to the Aircraft.

-25-

11.6 CITIZENSHIP OF OWNER PARTICIPANT

If at any time there shall be more than one Owner Participant, then any Owner Participant who shall cease to be a Citizen of the United States shall have no voting or similar rights under this Trust Agreement and shall have no right to direct, influence or limit the exercise of, or to prevent the direction or influence of, or place any limitation on the exercise of, Owner Trustee's authority or to remove Owner Trustee.

If, however, any Law pursuant to which such provisions are held invalid, illegal or unenforceable may be waived, such Law is


-26-

hereby waived by the parties hereto to the full extent permitted, to the end that this Trust Agreement shall be deemed to be a valid and binding agreement in all respects, enforceable in accordance with its terms.

11.9 WAIVERS, ETC.

No term or provision hereof may be changed, waived, discharged or terminated orally, but only by an instrument in writing entered into in compliance with the terms of Section 10; and any waiver of the terms hereof shall be effective only in the specific instance and for the specific purpose given.

(iii) to the effect that the tax and other indemnities in favor of each person named as an indemnitee under any other Operative Agreement afford each


-23-

such person substantially the same protection as provided prior to such change of registration (or Owner shall have agreed upon additional indemnities that, together with such original indemnities, in the reasonable judgment of Mortgagee, afford such protection).

8.1.4 NOTICE

If a claim for any Expense that an Indemnitee shall be indemnified against under this Section 8.1 is made, such Indemnitee shall give prompt written notice thereof to Owner. Notwithstanding the foregoing, the failure of any Indemnitee to notify Owner as provided in this Section 8.1.4, or in Section 8.1.5, shall not release Owner from any of its obligations to indemnify such Indemnitee hereunder, except to the extent that such failure results in an additional Expense to Owner (in which event Owner shall not be responsible for such additional Expense) or materially impairs Owner's ability to contest such claim.

8.1.5 NOTICE OF PROCEEDINGS; DEFENSE OF CLAIMS; LIMITATIONS

(a) In case any action, suit or proceeding shall be brought against any Indemnitee for which Owner is responsible under this Section 8.1, such Indemnitee shall notify Owner of the commencement thereof and Owner may, at its expense, participate in and to the extent that it shall wish (subject to the provisions of the following paragraph), assume and control the defense thereof and, subject to Section 8.1.5(c), settle or compromise the same.

-29-

any such Expense during the continuance of any Event of Default. In connection with any such action, suit or proceeding being controlled by Owner, such Indemnitee shall have the right to participate therein, at its sole cost and expense, with counsel reasonably satisfactory to Owner; provided, that such Indemnitee's participation does not, in the reasonable opinion of the independent counsel appointed by the Owner or its insurers to conduct such proceedings, interfere with the defense of such case.

(d) In the case of any Expense indemnified by the Owner hereunder which is covered by a policy of insurance maintained by Owner pursuant to Section 4.06 of the Indenture, at Owner's expense, each Indemnitee agrees to cooperate with the insurers in the exercise of their rights to investigate, defend or compromise such Expense as may be required to retain the benefits of such insurance with respect to such Expense.

Section 12.8 prior to making any payment to such Indemnitee under this Section 8.

8.1.6 INFORMATION

Owner will provide the relevant Indemnitee with such information not within the control of such Indemnitee, as is in Owner's control or is reasonably available to Owner, which such Indemnitee may reasonably request and will otherwise cooperate with such Indemnitee so as to enable such Indemnitee to fulfill its obligations under Section 8.1.5.

-30-

8.1.7 EFFECT OF OTHER INDEMNITIES; SUBROGATION; FURTHER ASSURANCES

Upon the payment in full by Owner of any indemnity provided for under this Agreement, Owner, without any further action and to the full extent permitted by Law, will be subrogated to all rights and remedies of the person indemnified (other than with respect to any of such Indemnitee's insurance policies or in connection with any indemnity claim such Indemnitee may have under Section 6.03 or 8.01 of the Trust Indenture) in respect of the matter as to which such indemnity was paid. Each Indemnitee will give such further assurances or agreements and cooperate with Owner to permit Owner to pursue such claims, if any, to the extent reasonably requested by Owner and at Owner's expense.

8.1.8 REFUNDS

If an Indemnitee receives any refund, in whole or in part, with respect to any Expense paid by Owner hereunder, it will promptly pay the amount refunded (but not an amount in excess of the amount Owner or any of its insurers has paid in respect of such Expense) over to Owner unless an Event of Default shall have occurred and be continuing, in which case such amounts shall be paid over to Mortgagee to hold as security for Owner's obligations under the Operative Agreements or, if requested by Owner, applied to satisfy such obligations.

If so submitted and approved, the Owner agrees promptly, but in any event no later than the 105th day after the Closing Date, to pay Transaction Expenses.

(l) imposed on a Tax Indemnitee by a Taxing Authority of a jurisdiction outside the United States to the extent that such Taxes would not have been imposed but for a connection between the Tax Indemnitee or a related Tax Indemnitee and such jurisdiction imposing such Tax unrelated to the transactions contemplated by the Operative Agreements; or

For purposes hereof, a Tax Indemnitee and any other Tax Indemnitees that are successors, assigns, agents, servants or Affiliates of such Tax Indemnitee shall be related Tax Indemnitees.

8.3.3 PAYMENT

(a) Owner's indemnity obligation to a Tax Indemnitee under this Section 8.3 shall equal the amount which, after taking into account any Tax imposed upon the receipt or accrual of the amounts payable under this Section 8.3 and any tax benefits actually recognized by such Tax Indemnitee as a result of the indemnifiable Tax (including, without limitation, any benefits recognized as a result of an indemnifiable Tax being utilized by such Tax Indemnitee as a credit against Taxes not indemnifiable under this


-35-

Section 8.3), shall equal the amount of the Tax indemnifiable under this Section 8.3.

(b) At Owner's request, the computation of the amount of any indemnity payment owed by Owner or any amount owed by a Tax Indemnitee to Owner pursuant to this Section 8.3 shall be verified and certified by an independent public accounting firm selected by such Tax Indemnitee and reasonably satisfactory to Owner. Such verification shall be binding. The costs of such verification (including the fee of such public accounting firm) shall be borne by Owner unless such verification shall result in an adjustment in Owner's favor of 5% or more of the net present value of the payment as computed by such Tax Indemnitee, in which case the costs shall be paid by such Tax Indemnitee.

(c) Each Tax Indemnitee shall provide Owner with such certifications, information and documentation as shall be in such Tax Indemnitee's possession and as shall be reasonably requested by Owner to minimize any indemnity payment pursuant to this Section 8.3; provided, that notwithstanding anything to the contrary contained herein, no Tax Indemnitee shall be required to provide Owner with any Tax returns.

(d) Each Tax Indemnitee shall promptly forward to Owner any written notice, bill or advice received by it from any Taxing Authority concerning any Tax for which it seeks indemnification under this Section 8.3. Owner shall pay any amount for which it is liable pursuant to this Section 8.3 directly to the appropriate Taxing Authority if legally permissible or upon demand of a Tax Indemnitee, to such Tax Indemnitee within 30 days of such demand (or, if a contest occurs in accordance with Section 8.3.4, within 30 days after a Final Determination (as defined below)), but in no event more than one Business Day prior to the date the Tax to which such amount payable hereunder relates is due. If requested by a Tax Indemnitee in writing, Owner shall furnish to the appropriate Tax Indemnitee the original or a certified copy of a receipt for Owner's payment of any Tax paid by Owner or such other evidence of payment of such Tax as is acceptable to such Tax Indemnitee. Owner shall also furnish promptly upon written request such data as any Tax Indemnitee may reasonably require to enable such Tax Indemnitee to comply with the requirements of any taxing jurisdiction unless such data is not reasonably available to Owner or, unless such data is specifically requested by a Taxing Authority, is not customarily furnished by domestic air carriers under similar circumstances. For purposes of this Section 8.3, a "Final Determination" shall mean (i) a decision, judgment, decree or other order by any court of competent jurisdiction that occurs pursuant to the provisions of Section 8.3.4, which decision, judg-


-36-

ment, decree or other order has become final and unappealable, (ii) a closing agreement or settlement agreement entered into in accordance with Section 8.3.4 that has become binding and is not subject to further review or appeal (absent fraud, misrepresentation, etc.), or (iii) the termination of administrative proceedings and the expiration of the time for instituting a claim in a court proceeding.

(e) If any Tax Indemnitee shall actually realize a tax savings by reason of any Tax paid or indemnified by Owner pursuant to this Section 8.3 (whether such tax savings shall be by means of a foreign tax credit, depreciation or cost recovery deduction or otherwise) and such savings is not otherwise taken into account in computing such payment or indemnity such Tax Indemnitee shall pay to Owner an amount equal to the lesser of (i) the amount of such tax savings, plus any additional tax savings recognized as the result of any payment made pursuant to this sentence, when, as, if, and to the extent, realized or (ii) the amount of all payments pursuant to this Section 8.3 by Owner to such Tax Indemnitee (less any payments previously made by such Tax Indemnitee to Owner pursuant to this Section 8.3.3 (e)) (and the excess, if any, of the amount described in clause (i) over the amount described in clause (ii) shall be carried forward and applied to reduce pro tanto any subsequent obligations of Owner to make payments to such Tax Indemnitee pursuant to this
Section 8.3); provided, that such Tax Indemnitee shall not be required to make any payment pursuant to this sentence so long as a Lease Event of Default of a monetary nature has occurred and is continuing. If a tax benefit is later disallowed or denied, the disallowance or denial shall be treated as a Tax indemnifiable under Section 8.3.1 without regard to the provisions of Section
8.3.2 (other than Section 8.3.2 (f)). Each such Tax Indemnitee shall in good faith use reasonable efforts in filing its tax returns and in dealing with Taxing Authorities to seek and claim any such tax benefit.

8.3.4 CONTEST

(a) If a written claim is made against a Tax Indemnitee for Taxes with respect to which Owner could be liable for payment or indemnity hereunder, or if a Tax Indemnitee makes a determination that a Tax is due for which Owner could have an indemnity obligation hereunder, such Tax Indemnitee shall promptly give Owner notice in writing of such claim (provided, that failure to so notify Owner shall not relieve Owner of its indemnity obligations hereunder unless such failure to notify effectively forecloses Owner's rights to require a contest of such claim) and shall take no action with respect to such claim without the prior written consent of Owner for 30 days following the receipt of such notice


-37-

by Owner; provided, that, in the case of a claim made against a Tax Indemnitee, if such Tax Indemnitee shall be required by law to take action prior to the end of such 30-day period, such Tax Indemnitee shall, in such notice to Owner, so inform Owner, and such Tax Indemnitee shall take no action for as long as it is legally able to do so (it being understood that a Tax Indemnitee shall be entitled to pay the Tax claimed and sue for a refund prior to the end of such 30-day period if (i)(A) the failure to so pay the Tax would result in substantial penalties (unless immediately reimbursed by Owner) and the act of paying the Tax would not materially prejudice the right to contest or (B) the failure to so pay would result in criminal penalties and (ii) such Tax Indemnitee shall take any action so required in connection with so paying the Tax in a manner that is the least prejudicial to the pursuit of the contest). In addition, such Tax Indemnitee shall (provided, that Owner shall have agreed to keep such information confidential other than to the extent necessary in order to contest the claim) furnish Owner with copies of any requests for information from any Taxing Authority relating to such Taxes with respect to which Owner may be required to indemnify hereunder. If requested by Owner in writing within 30 days after its receipt of such notice, such Tax Indemnitee shall, at the expense of Owner (including, without limitation, all reasonable costs, expenses and reasonable attorneys' and accountants' fees and disbursements), in good faith contest (or, if permitted by applicable law, allow Owner to contest) through appropriate administrative and judicial proceedings the validity, applicability or amount of such Taxes by (I) resisting payment thereof, (II) not paying the same except under protest if protest is necessary and proper or (III) if the payment is made, using reasonable efforts to obtain a refund thereof in an appropriate administrative and/or judicial proceeding. If requested to do so by Owner, the Tax Indemnitee shall appeal any adverse administrative or judicial decision, except that the Tax Indemnitee shall not be required to pursue any appeals to the United States Supreme Court. If and to the extent the Tax Indemnitee is able to separate the contested issue or issues from other issues arising in the same administrative or judicial proceeding that are unrelated to the transactions contemplated by the Operative Agreements without, in the good faith judgment of such Tax Indemnitee, adversely affecting such Tax Indemnitee, such Tax Indemnitee shall permit Owner to control the conduct of any such proceeding and shall provide to Owner (at Owner's cost and expense) with such information or data that is in such Tax Indemnitee's control or possession that is reasonably necessary to conduct such contest. In the case of a contest controlled by a Tax Indemnitee, such Tax Indemnitee shall consult with Owner in good faith regarding the manner of contesting such claim and shall keep Owner reasonably informed regarding the progress of such contest. A Tax Indemnitee


-38-

shall not fail to take any action expressly required by this Section 8.3.4 (including, without limitation, any action regarding any appeal of an adverse determination with respect to any claim) or settle or compromise any claim without the prior written consent of the Owner (except as contemplated by
Section 8.3.4(b) or (c)).

(b) Notwithstanding the foregoing, in no event shall a Tax Indemnitee be required to pursue any contest (or to permit Owner to pursue any contest) unless (i) Owner shall have agreed to pay such Tax Indemnitee on demand all reasonable costs and expenses incurred by such Tax Indemnitee in connection with contesting such Taxes, including, without limitation, all reasonable out of pocket costs and expenses and reasonable attorneys' and accountants' fees and disbursements, (ii) if such contest shall involve the payment of the claim, Owner shall advance the amount thereof (to the extent indemnified hereunder) plus interest, penalties and additions to tax with respect thereto that are required to be paid prior to the commencement of such contest on an interest-free after-Tax basis to such Tax Indemnitee (and such Tax Indemnitee shall promptly pay to the Owner any net realized tax benefits resulting from such advance including any tax benefits resulting from making such payment),
(iii) such Tax Indemnitee shall have reasonably determined that the action to be taken will not result in any material risk of forfeiture, sale or loss of the Aircraft (unless Owner shall have made provisions to protect the interests of any such Tax Indemnitee in a manner reasonably satisfactory to such Tax Indemnitee) (provided, that such Tax Indemnitee agrees to notify Owner in writing promptly after it becomes aware of any such risk), (iv) no Lease Event of Default shall have occurred and be continuing unless Owner has provided security for its obligations hereunder by advancing to such Tax Indemnitee before proceeding or continuing with such contest, the amount of the Tax being contested, plus any interest and penalties and an amount estimated in good faith by such Tax Indemnitee for expenses, and (v) prior to commencing any judicial action controlled by Owner, Owner shall have acknowledged its liability for such claim hereunder, provided that Owner shall not be bound by its acknowledgment if the Final Determination articulates conclusions of law and fact that demonstrate that Owner has no liability for the contested amounts hereunder. Notwithstanding the foregoing, if any Tax Indemnitee shall release, waive, compromise or settle any claim which may be indemnifiable by owner pursuant to this Section 8.3 without the written permission of Owner, Owner's obligation to indemnify such Tax Indemnitee with respect to such claim (and all directly related claims and claims based on the outcome of such claim) shall terminate, subject to Section 8.3.4(c), and subject to Section 8.3.4(c), such Tax Indemnitee shall repay to Owner any


-39-

amount previously paid or advanced to such Tax Indemnitee with respect to such claim, plus interest at the rate that would have been payable by the relevant Taxing Authority with respect to a refund of such Tax.

(c) Notwithstanding anything contained in this Section 8.3, a Tax Indemnitee will not be required to contest the imposition of any Tax and shall be permitted to settle or compromise any claim without Owner's consent if such Tax Indemnitee (i) shall waive its right to indemnity under this Section 8.3 with respect to such Tax (and any directly related claim and any claim the outcome of which is determined based upon the outcome of such claim), (ii) shall pay to Owner any amount previously paid or advanced by Owner pursuant to this
Section 8.3 with respect to such Tax, plus interest at the rate that would have been payable by the relevant Taxing Authority with respect to a refund of such Tax, and (iii) shall agree to discuss with Owner the views or positions of any relevant Taxing Authority with respect to the imposition of such Tax.

8.3.5 REFUND

If any Tax Indemnitee shall receive a refund of, or be entitled to a credit against other liability for, all or any part of any Taxes paid, reimbursed or advanced by Owner, such Tax Indemnitee shall pay to Owner within 30 days of such receipt an amount equal to the lesser of (a) the amount of such refund or credit plus any net tax benefit (taking into account any taxes incurred by such Tax Indemnitee by reason of the receipt of such refund or realization of such credit) actually realized by such Tax Indemnitee as a result of any payment by such Tax Indemnitee made pursuant to this sentence (including this clause (a)) and (b) such tax payment, reimbursement or advance by Owner to such Tax Indemnitee theretofore made pursuant to this Section 8.3 (and the excess, if any, of the amount described in clause (a) over the amount described in clause (b) shall be carried forward and applied to reduce pro tanto any subsequent obligation of Owner to make payments to such Tax Indemnitee pursuant to this Section 8.3). If, in addition to such refund or credit, such Tax Indemnitee shall receive (or be credited with) an amount representing interest on the amount of such refund or credit, such Tax Indemnitee shall pay to owner within 30 days of such receipt or realization of such credit that proportion of such interest that shall be fairly attributable to Taxes paid, reimbursed or advanced by Owner prior to the receipt of such refund or realization of such credit.


-40-

8.3.6 TAX FILING

If any report, return or statement is required to be filed with respect to any Tax which is subject to indemnification under this Section 8.3, Owner shall timely file the same (except for any such report, return or statement which a Tax Indemnitee has timely notified the Owner in writing that such Tax Indemnitee intends to file, or for which such Tax Indemnitee is required by law to file, in its own name); provided, that the relevant Tax Indemnitee shall furnish Owner with any information in such Tax Indemnitee's possession or control that is reasonably necessary to file any such return, report or statement and is reasonably requested in writing by Owner (it being understood that the Tax Indemnitee shall not be required to furnish copies of its actual tax returns, although it may be required to furnish relevant information contained therein). Owner shall either file such report, return or statement and send a copy of such report, return or statement to such Tax Indemnitee, or, where Owner is not permitted to file such report, return or statement, it shall notify such Tax Indemnitee of such requirement and prepare and deliver such report, return or statement to such Tax Indemnitee in a manner satisfactory to such Tax Indemnitee within a reasonable time prior to the time such report, return or statement is to be filed.

8.3.7 FORMS

Each Tax Indemnitee agrees to furnish from time to time to Owner or Mortgagee or to such other person as Owner or Mortgagee may designate, at Owner's or Mortgagee's request, such duly executed and properly completed forms as may be necessary or appropriate in order to claim any reduction of or exemption from any withholding or other Tax imposed by any Taxing Authority, if
(x) such reduction or exemption is available to such Tax Indemnitee and (y) Owner has provided such Tax Indemnitee with any information necessary to complete such form not otherwise reasonably available to such Tax Indemnitee.

8.3.8 NON-PARTIES

If a Tax Indemnitee is not a party to this Agreement, Owner may require the Tax Indemnitee to agree in writing, in a form reasonably acceptable to Owner, to the terms of this Section 8.3 and Section 15.8 prior to making any payment to such Tax Indemnitee under this Section 8.3.

Upon payment of any Tax by Owner pursuant to this Section 8.3 to or on behalf of a Tax Indemnitee, Owner, without any further action, shall be subrogated to any claims that such Tax Indemnitee may have relating thereto. Such Tax Indemnitee shall cooperate with Owner (to the extent such cooperation does not result in any unreimbursed cost, expense or liability to such Tax Indemnitee) to permit Owner to pursue such claims.

8.4. PAYMENTS

Any payments made pursuant to Section 8.1 or 8.3 shall be due on the 60th day after demand therefor and shall be made directly to the relevant Indemnitee or Tax Indemnitee or to Owner, in immediately available funds at such bank or to such account as specified by such Indemnitee or Tax Indemnitee or Owner, as the case may be, in written directives to the payor, or, if no such direction shall have been given, by check of the payor payable to the order of, and mailed to, such Indemnitee or Tax Indemnitee or Owner, as the case may be, by certified mail, postage prepaid, at its address as set forth in this Agreement.

8.5. INTEREST

If any amount, payable by Owner, any Indemnitee or any Tax Indemnitee under Section 8.1 or 8.3 is not paid when due, the person obligated to make such payment shall pay on demand, to the extent permitted by Law, to the person entitled thereto, interest on any such amount for the period from and including the due date for such amount to but excluding the date the same is paid, at the Payment Due Rate.

The Original Amount of each Equipment Note shall be payable on the dates and in the installments equal to the corresponding percentage of the Original Amount as set forth in Schedule I hereto the applicable portion of which shall be attached as Schedule I to the Equipment Notes (or, in the case of the Series D Equipment Notes if issued after the Closing Date, as set forth in an amendment to this Trust Indenture, which payment schedule shall be attached as Schedule I to the Series D Equipment Notes). Notwithstanding the foregoing, the final payment made under each Equipment Note shall be in an amount sufficient to discharge in full the unpaid Original Amount and all accrued and unpaid interest on, and any other amounts due under, such Equipment Note. Each Equipment Note shall bear interest at the Payment Due Rate (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any part of the Original Amount, Make-Whole Amount, if any, and, to the extent permitted by applicable Law, interest and any other amounts payable thereunder not paid when due for any period during which the same shall be overdue, in each case for the period the same is overdue. Amounts shall be overdue if not paid when due (whether at stated maturity, by acceleration or otherwise). Notwithstanding anything to the contrary contained herein, if any date on which a payment under any Equipment Note becomes due and payable is not a Business Day then such payment shall not be made on such scheduled date but shall be made on the next succeeding Business Day and if such payment is made on such next succeeding Business Day, no interest shall accrue on the amount of such payment during such extension.

(v) Owner's pro rata share of any other amounts owed to the Liquidity Providers by the Subordination Agent as borrower under each Liquidity Facility other than amounts due as repayment of advances thereunder or as interest on such advances, except to the extent payable pursuant to clause (ii), (iii) or (iv) above, (c) Owner's pro rata share of all compensation and reimbursement of expenses, disbursements and advances payable by Owner under the Pass Through Trust Agreements, (d) Owner's pro rata share of all compensation and reimbursement of expenses and disbursements payable to the Subordination Agent under the Intercreditor

Agreement except with respect to any income or franchise taxes incurred by the Subordination Agent in connection with the transactions contemplated by the Intercreditor Agreement and (e) in the event Owner requests any amendment to any Operative Agreement or Pass Through Agreement, Owner's pro rata share of all reasonable fees and expenses (including, without limitation, fees and disbursements of counsel) of the Escrow Agents and the Paying Agents in connection therewith payable by the Pass Through Trustees under the Escrow Agreements. As used herein, "Owner's pro rata share" means as of any time a fraction, the numerator of which is the principal balance then outstanding of Equipment Notes and the denominator of which is the aggregate principal balance then outstanding of all "Equipment Notes" (as such term is defined in each of the Operative Indentures). For purposes of this paragraph, the terms "Applied Downgrade Advance," "Applied Non-Extension Advance," "Cash Collateral Account," "Downgrade Advance," "Final Advance," "Investment Earnings," "Non-Extension Advance" and "Unpaid Advance" shall have the meanings specified in each Liquidity Facility.

The Equipment Notes shall be executed on behalf of the Owner by one of its authorized officers. Equipment Notes bearing the signatures of individuals who were at any time the proper officers of the Owner shall bind the Owner, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Equipment Notes or did not hold such offices at the respective dates of such Equipment Notes. The Owner may from time to time execute and deliver Equipment Notes with respect to the Aircraft to the Mortgagee for authentication upon original issue and such Equipment Notes shall thereupon be authenticated and delivered by the Mortgagee upon the written request of the Owner signed by an authorized officer of the Owner. No Equipment Note shall be secured by or entitled to any benefit under this Trust Indenture or be valid or obligatory for any purposes, unless there appears on such Equipment Note a certificate of authentication in the form provided for herein executed by the Mortgagee by the manual signature of one of its authorized officers and such certificate upon any Equipment Notes be conclusive evidence, and the only evidence, that such Equipment Note has been duly authenticated and delivered hereunder.

The aggregate Original Amount of the Equipment Notes issued hereunder shall not exceed the amount set forth as the maximum therefor on Schedule I hereto.

SECTION 2.03. [INTENTIONALLY OMITTED]

SECTION 2.04. METHOD OF PAYMENT

(a) The Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due under each Equipment Note or hereunder will be payable in Dollars by


-14-

wire transfer of immediately available funds not later than 12 noon, New York time, on the due date of payment to the Mortgagee at the Corporate Trust Office for distribution among the Note Holders in the manner provided herein. The Owner shall not have any responsibility for the distribution of such payment to any Note Holder. Notwithstanding the foregoing or any provision in any Equipment Note to the contrary, the Mortgagee will use reasonable efforts to pay or cause to be paid, if so directed in writing by any Note Holder (with a copy to the Owner), all amounts paid by the Owner hereunder and under such holder's Equipment Note or Equipment Notes to such holder or a nominee therefor (including all amounts distributed pursuant to Article III of this Trust Indenture) by transferring, or causing to be transferred, by wire transfer of immediately available funds in Dollars, prior to 12:30 P.M., New York City time, on the due date of payment, to an account maintained by such holder with a bank located in the continental United States the amount to be distributed to such holder, for credit to the account of such holder maintained at such bank. Any payment made hereunder shall be made without any presentment or surrender of any Equipment Note, except that, in the case of the final payment in respect of any Equipment Note, such Equipment Note shall be surrendered to the Mortgagee for cancellation promptly after such payment. Notwithstanding any other provision of this Trust Indenture to the contrary, the Mortgagee shall not be required to make, or cause to be made, wire transfers as aforesaid prior to the first Business Day on which it is practicable-for the Mortgagee to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 12 noon, New York time, at the place of payment. Prior to the due presentment for registration of transfer of any Equipment Note, the Owner and the Mortgagee shall deem and treat the Person in whose name any Equipment Note is registered on the Equipment Note Register as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable with respect to such Equipment Note and for all other purposes, and none of the Owner or the Mortgagee shall be affected by any notice to the contrary. So long as any signatory to the Participation Agreement or nominee thereof shall be a registered Note Holder, all payments to it shall be made to the account of such Note Holder specified in Schedule I thereto and otherwise in the manner provided in or pursuant to the Participation Agreement unless it shall have specified some other account or manner of payment by notice to the Mortgagee consistent with this Section 2.04.

(b) The Mortgagee, as agent for the Owner, shall exclude and withhold at the appropriate rate from each payment of Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due hereunder or under each Equipment Note (and such exclusion and withholding shall constitute payment in respect of such Equipment Note) any and all United States withholding taxes applicable thereto as required by Law. The Mortgagee agrees to act as such withholding agent and, in connection therewith, whenever any present or future United States taxes or similar charges are required to be withheld with respect to any amounts


-15-

payable hereunder or in respect of the Equipment Notes, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of the Note Holders, that it will file any necessary United States withholding tax returns or statements when due, and that as promptly as possible after the payment thereof it will deliver to each Note Holder (with a copy to the Owner) appropriate receipts showing the payment thereof, together with such additional documentary evidence as any such Note Holder may reasonably request from time to time.

If a Note Holder which is a Non-U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form 1001 or W-8 (or such successor form or forms as may be required by the United States Treasury Department) during the calendar year in which the payment hereunder or under the Equipment Note(s) held by such holder is made (but prior to the making of such payment), or in either of the two preceding calendar years, and has not notified the Mortgagee of the withdrawal or inaccuracy of such form prior to the date of such payment (and the Mortgagee has no reason to believe that any information set forth in such form is inaccurate), the Mortgagee shall withhold only the amount, if any, required by Law (after taking into account any applicable exemptions properly claimed by the Note Holder) to be withheld from payments hereunder or under the Equipment Notes held by such holder in respect of United States federal income tax. If a Note Holder (x) which is a Non-U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form 4224 in duplicate (or such successor certificate, form or forms as may be required by the United States Treasury Department as necessary in order to properly avoid withholding of United States federal income tax), for each calendar year in which a payment is made (but prior to the making of any payment for such year), and has not notified the Mortgagee of the withdrawal or inaccuracy of such certificate or form prior to the date of such payment (and the Mortgagee has no reason to believe that any information set forth in such form is inaccurate) or (y) which is a U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W9, if applicable, prior to a payment hereunder or under the Equipment Notes held by such holder, no amount shall be withheld from payments in respect of United States federal income tax. If any Note Holder has notified the Mortgagee that any of the foregoing forms or certificates is withdrawn or inaccurate, or if such holder has not filed a form claiming an exemption from United States withholding tax or if the Code or the regulations thereunder or the administrative interpretation thereof is at any time after the date hereof amended to require such withholding of United States federal income taxes from payments under the Equipment Notes held by such holder, the Mortgagee agrees to withhold from each payment due to the relevant Note Holder withholding taxes at the appropriate rate under Law and will, on a timely basis as more fully provided above, deposit such amounts with an authorized depository and make such returns,


-16-

statements, receipts and other documentary evidence in connection therewith as required by Law.

Owner shall not have any liability for the failure of the Mortgagee to withhold taxes in the manner provided for herein or for any false, inaccurate or untrue evidence provided by any Note Holder hereunder.

SECTION 2.05. APPLICATION OF PAYMENTS

In the case of each Equipment Note, each payment of Original Amount, Make-Whole Amount, if any, and interest due thereon shall be applied:

First: to the payment of accrued interest on such Equipment Note (as well as any interest on any overdue Original Amount, any overdue Make-Whole Amount, if any, and to the extent permitted by Law, any overdue interest and any other overdue amounts thereunder) to the date of such payment;

Second: to the payment of the Original Amount of such Equipment Note (or a portion thereof) then due thereunder;

Third: to the payment of Make-Whole Amount, if any, and any other amount due hereunder or under such Equipment Note: and

Fourth: the balance, if any, remaining thereafter, to the payment of the Original Amount of such Equipment Note remaining unpaid (provided that such Equipment Note shall not be subject to redemption except as provided in Sections 2.10, 2.11 and 2.12 hereof).

The amounts paid pursuant to clause "Fourth" above shall be applied to the installments of Original Amount of such Equipment Note in the inverse order of their maturity.

SECTION 2.06. TERMINATION OF INTEREST IN COLLATERAL

No Note Holder nor any other Indenture Indemnitee shall, as such, have any further interest in, or other right with respect to, the Collateral when and if the Original Amount of, Make-Whole Amount, if any, and interest on and other amounts due under all Equipment Notes held by such Note Holder and any other sums then due and payable to such Note Holder, such Indenture Indemnitee or the Mortgagee hereunder (including, without limitation, under the third paragraph of
Section 2.02 hereof) and under the other Operative


-17-

Agreements by the Owner (collectively, the "Secured Obligations") shall have been paid in full.

SECTION 2.07. REGISTRATION TRANSFER AND EXCHANGE OF EQUIPMENT NOTES

The Mortgagee shall keep a register (the "Equipment Note Register") in which the Mortgagee shall provide for the registration of Equipment Notes and the registration of transfers of Equipment Notes. No such transfer shall be given effect unless and until registration hereunder shall have occurred. The Equipment Note Register shall be kept at the Corporate Trust Office of the Mortgagee. The Mortgagee is hereby appointed "Equipment Note Registrar" for the purpose of registering Equipment Notes and transfers of Equipment Notes as herein provided. A holder of any Equipment Note intending to exchange such Equipment Note shall surrender such Equipment Note to the Mortgagee at the Corporate Trust Office, together with a written request from the registered holder thereof for the issuance of a new Equipment Note, specifying, in the case of a surrender for transfer, the name and address of the new holder or holders. Upon surrender for registration of transfer of any Equipment Note, the Owner shall execute, and the Mortgagor shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Equipment Notes of a like aggregate Original Amount and of the same series. At the option of the Note Holder, Equipment Notes may be exchanged for other Equipment Notes of any authorized denominations of a like aggregate Original Amount, upon surrender of the Equipment Notes to be exchanged to the Mortgagee at the Corporate Trust Office. Whenever any Equipment Notes are so surrendered for exchange, the Owner shall execute, and the Mortgagee shall authenticate and deliver, the Equipment Notes which the Note Holder making the exchange is entitled to receive. All Equipment Notes issued upon any registration of transfer or exchange of Equipment Notes (whether under this Section 2.07 or under Section 2.08 hereof or otherwise under this Trust Indenture) shall be the valid obligations of the Owner evidencing the same respective obligations, and entitled to the same security and benefits under this Trust Indenture, as the Equipment Notes surrendered upon such registration of transfer or exchange. Every Equipment Note presented or surrendered for registration of transfer, shall (if so required by the Mortgagee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Mortgagee duly executed by the Note Holder or such holder's attorney duly authorized in writing, and the Mortgagee shall require evidence satisfactory to it as to the compliance of any such transfer with the Securities Act, and the securities Laws of any applicable state. The Mortgagee shall make a notation on each new Equipment Note of the amount of all payments of Original Amount previously made on the old Equipment Note or Equipment Notes with respect to which such new Equipment Note is issued and the date to which interest on such old Equipment Note or Equipment Notes has been paid. Interest shall be


-18-

deemed to have been paid on such new Equipment Note to the date on which interest shall have been paid on such old Equipment Note, and all payments of the Original Amount marked on such new Equipment Note, as provided above, shall be deemed to have been made thereon. The Owner shall not be required to exchange any surrendered Equipment Notes as provided above during the ten-day period preceding the due date of any payment on such Equipment Note. The Owner shall in all cases deem the Person in whose name any Equipment Note shall have been issued and registered as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable by the Owner with respect to such Equipment Note and for all purposes until a notice stating otherwise is received from the Mortgagee and such change is reflected on the Equipment Note Register. The Mortgagee will promptly notify the Owner of each registration of a transfer of an Equipment Note. Any such transferee of an Equipment Note, by its acceptance of an Equipment Note, agrees to the provisions of this Trust Indenture and the Participation Agreement applicable to Note Holders, including Sections 6.3, 6.4 and 9.1 thereof and shall be deemed to have covenanted to the parties to the Participation Agreement as to the matters covenanted by the original Note Holder in the Participation Agreement. Subject to compliance by the Note Holder and its transferee (if any) of the requirements set forth in this Section 2.07, Mortgagee and Owner shall use all reasonable efforts to issue new Equipment Notes upon transfer or exchange within 10 Business Days of the date an Equipment Note is surrendered for transfer or exchange.

SECTION 2.08. MUTILATED, DESTROYED, LOST OR STOLEN EQUIPMENT NOTES

If any Equipment Note shall become mutilated, destroyed, lost or stolen, the Owner shall, upon the written request of the holder of such Equipment Note, execute and the Mortgagee shall authenticate and deliver in replacement thereof a new Equipment Note, payable in the same Original Amount dated the same date and captioned as issued in connection with the Aircraft. If the Equipment Note being replaced has become mutilated, such Equipment Note shall be surrendered to the Mortgagee and a photocopy thereof shall be furnished to the Owner. If the Equipment Note being replaced has been destroyed, lost or stolen, the holder of such Equipment Note shall furnish to the Owner and the Mortgagee such security or indemnity as may be required by them to save the Owner and the Mortgagee harmless and evidence satisfactory to the Owner and the Mortgagee of the destruction, loss or theft of such Equipment Note and of the ownership thereof. If a "qualified institutional buyer" of the type referred to in paragraph (a)(1)(i)(A), (B), (D) or (E) of Rule 144A under the Securities Act (a "QIB") is the holder of any such destroyed, lost or stolen Equipment Note, then the written indemnity of such QIB, signed by an authorized officer thereof, in favor of, delivered to and in form reasonably satisfactory to the Owner shall be accepted as satisfactory indemnity and


-19-

security and no further indemnity or security shall be required as a condition to the execution and delivery of such new Equipment Note. Subject to compliance by the Note Holder with the requirements set forth in this Section 2.08, Mortgagee and Owner shall use all reasonable efforts to issue new Equipment Notes within 10 Business Days of the date of the written request therefor from the Note Holder.

SECTION 2.09. PAYMENT OF EXPENSES ON TRANSFER; CANCELLATION

(a) No service charge shall be made to a Note Holder for any registration of transfer or exchange of Equipment Notes, but the Mortgagee, as Equipment Note Registrar, may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Equipment Notes.

(b) The Mortgagee shall cancel all Equipment Notes surrendered for replacement, redemption, transfer, exchange, payment or cancellation and shall destroy the canceled Equipment Notes.

SECTION 2.10. MANDATORY REDEMPTIONS OF EQUIPMENT NOTES

On the date on which the Owner is required pursuant to Section 4.05 hereof to make payment for an Event of Loss with respect to the Airframe, all of the Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with all accrued interest thereon to the date of redemption and all other Secured Obligations owed or then due and payable to the Note Holders but without Make-Whole Amount.

SECTION 2.11. VOLUNTARY REDEMPTIONS OF EQUIPMENT NOTES

All (but not less than all) of the Equipment Notes may be redeemed by the Owner upon at least 20 days revocable prior written notice to the Mortgagee and the Note Holders, and the Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with accrued interest thereon to the date of redemption and all other Secured Obligations owed or then-due and payable to the Note Holders plus Make-Whole Amount, if any.


-20-

SECTION 2.12. REDEMPTIONS; NOTICE OF REDEMPTION

(a) No redemption of any Equipment Note may be made except to the extent and in the manner expressly permitted by this Trust Indenture. No purchase of any Equipment Note may be made by the Mortgagee.

(b) Notice of redemption with respect to the Equipment Notes shall be given by the Mortgagee by first-class mail, postage prepaid, mailed not less than 15 nor more than 60 days prior to the applicable redemption date, to each Note Holder of such Equipment Notes to be redeemed, at such Note Holder's address appearing in the Equipment Note Register; provided that such notice shall be revocable by written notice from the Owner to Mortgagee given not later than three days prior to the redemption date. All notices of redemption shall state: (1) the redemption date, (2) the applicable basis for deter-mining the redemption price, (3) that on the redemption date, the redemption price will become due and payable upon each such Equipment Note, and that, if any such Equipment Notes are then outstanding, interest on such Equipment Notes shall cease to accrue on and after such redemption date, and (4) the place or places where such Equipment Notes are to be surrendered for payment of the redemption price.

(c) On or before the redemption date (unless the notice with respect thereto shall have been revoked pursuant to Section 2.12(b)), the Owner (or any person on behalf of the Owner) shall, to the extent an amount equal to the redemption price for the Equipment Notes to be redeemed on the redemption date shall not then be held by the Mortgagee, deposit or cause to be deposited with the Mortgagee by 12:30 PM New York time on the redemption date in immediately available funds the redemption price of the Equipment Notes to be redeemed.

(d) Notice of redemption having been given as aforesaid (and not revoked as contemplated in the proviso to Section 2.12(b)), the Equipment Notes to be redeemed shall, on the redemption date, become due and payable at the Corporate Trust Office of the Mortgagee or at any office or agency maintained for such purposes pursuant to Section 2.07, and from and after such redemption date (unless there shall be a default in the payment of the redemption price) any such Equipment Notes then outstanding shall cease to bear interest. Upon surrender of any such Equipment Note for redemption in accordance with said notice, such Equipment Note shall be redeemed at the redemption price. If any Equipment Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal amount thereof shall, until paid, continue to bear interest from the applicable redemption date at the interest rate in effect for such Equipment Note as of such redemption date.

SECTION 2.13. SUBORDINATION

(a) The Owner and, by acceptance of its Equipment Notes of any Series, each Note Holder of such Series, hereby agree that no payment or distribution shall be made on or in respect of the Secured Obligations owed to such Note Holder of such Series, including any payment or distribution of cash, property or securities after the commencement of a proceeding of the type referred to in
Section 5.01(e), (f) or (g) hereof, except as expressly provided in Article III hereof.

              Holders in reimbursement of such expenses and any other expenses
              for which the Mortgagee, WTC or the Note Holders are entitled to
              reimbursement under any Operative Agreement and (ii) pay all
              amounts payable to the other Indenture Indemnitees hereunder and

              accordance with the amount of the payment or payments made by each
              such then existing or prior Note Holder pursuant to said Section
              6.03 hereof;

(i) Subject or permit any Permitted Lessee to subject any Engine to normal interchange agreements or pooling agreements or arrangements, in each case customary


-29-

in the commercial airline industry and entered into by Owner or such Permitted Lessee, as the case may be, in the ordinary course of business; provided, however, that if Owner's title to any such Engine is divested under any such agreement or arrangement, then such Engine shall be deemed to have suffered an Event of Loss as of the date of such divestiture, and Owner shall comply with Section 4.04(e) in respect thereof;

(ii) Deliver or permit any Permitted Lessee to deliver possession of the Aircraft, Airframe, any Engine or any Part (x) to the manufacturer thereof or to any third-party maintenance provider for testing, service, repair, maintenance or overhaul work on the Aircraft, Airframe, any Engine or any Part, or, to the extent required or permitted by Section 4.04, for alterations or modifications in or additions to the Aircraft, Airframe or any Engine or (y) to any Person for the purpose of transport to a Person referred to in the preceding clause (x);

(y) Owner or Permitted Lessee, as the case may be, shall have received from the lessor, mortgagee, secured party or conditional seller, in respect of such airframe, a written agreement (which may be a copy of the lease, mortgage, security agreement, conditional sale or other agreement covering such airframe), whereby such Person agrees that it will not acquire or claim any right, title or interest in, or Lien on, such Engine by reason of such Engine being installed on such airframe at any time while such Engine is subject to the Lien of this Trust Indenture;

(v) Install or permit any Permitted Lessee to install an Engine on an airframe owned by Owner or such Permitted Lessee, leased to Owner or such Permitted Lessee, or purchased by Owner or such Permitted Lessee subject to a conditional sale or other security agreement under circumstances where neither clause (iii) or (iv) above is applicable;

(z) the agreement of such Permitted Air Carrier that its rights under the lease are subject and subordinate to all the terms of


-31-

this Trust Indenture is enforceable against such Permitted Air Carrier under applicable law;

provided that (1) the rights of any transferee who receives possession by reason of a transfer permitted by this Section 4.02(b) (other than by a transfer of an Engine which is deemed an Event of Loss) shall be subject and subordinate to all the terms of this Trust Indenture, (2) the Owner shall remain primarily liable for the performance of all of the terms of this Trust Indenture and all the terms and conditions of this Trust Indenture and the other Operative Agreements shall remain in effect and (3) no lease or transfer of possession otherwise in compliance with this Section 4.02(b) shall (x) result in any registration or re-registration of an Aircraft, except to the extent permitted by Section 4.02(e) or the maintenance, operation or use thereof except in compliance with Sections 4.02(c) and 4.02(d) or (y) permit any action not permitted to the Owner hereunder.

In the case of any lease permitted under this Section 4.02(b), the Owner will include in such lease appropriate provisions which (t) make such lease expressly subject and subordinate to all of the terms of this Trust Indenture, including the rights of the Mortgagee to avoid such lease in the exercise of its rights to repossession of the Airframe and Engines hereunder;
(u) require the Permitted Lessee to comply with the terms of Section 4.06; and
(v) require that the Airframe or any Engine subject thereto be used in accordance with the limitations applicable to the Owner's possession and use provided in this Trust Indenture. No lease permitted under this Section 4.02(b) shall be entered into unless (w) Owner shall provide written notice to Mortgagee and Standard & Poor's (such notice in the event of a lease to a U.S. Air Carrier to be given promptly after entering into any such lease or, in the case of a lease to any other Permitted Air Carrier, 10 days in advance of entering into such lease); (x) Owner shall furnish to Mortgagee evidence reasonably satisfactory to Mortgagee that the insurance required by Section 4.06 remains in effect; (y) all necessary documents shall have been duly filed, registered or recorded in such public offices as may be required fully to preserve the first priority security interest (subject to Permitted Liens) of Mortgagee in the Aircraft, Airframe and Engines; and (z) Owner shall reimburse Mortgagee for all of its reasonable out-of-pocket fees and expenses, including, without limitation, reasonable fees and disbursements of counsel, incurred by Mortgagee in connection with any such lease. For all purposes of this Section, the term "lease" shall be deemed to include interchange agreements with respect to the Aircraft or Airframe. Except as otherwise provided herein and without in any way relieving the Owner from its primary obligation for the performance of its obligations under this Trust Indenture, the Owner may in its sole discretion permit a lessee to exercise any or all rights which the Owner would be entitled to exercise under Sections 4.02 and 4.04, and may cause a lessee to perform any or all of the Owner's obligations under Article IV, and the


-32-

Mortgagee agrees to accept actual and full performance thereof by a lessee in lieu of performance by the Owner.

Mortgagee hereby agrees, and each Note Holder by acceptance of an Equipment Note agrees, for the benefit of each lessor, conditional seller, indenture trustee or secured party of any engine leased to, or purchased by, Owner or any Permitted Lessee subject to a lease, conditional sale, trust indenture or other security agreement that Mortgagee, each Note Holder and their respective successors and assigns will not acquire or claim, as against such lessor, conditional seller, indenture trustee or secured party, any right, title or interest in any engine as the result of such engine being installed on the Airframe at any time while such engine is subject to such lease, conditional sale, trust indenture or other security agreement and owned by such lessor or conditional seller or subject to a trust indenture or security interest in favor of such indenture trustee or secured party.

Notwithstanding anything to the contrary contained in this Trust Indenture or any other Operative Agreement, any charter, Wet Lease or ACMI Contract shall not constitute a delivery, transfer or relinquishment of possession for purposes of this Section 4.02(b) and shall not be prohibited by the terms hereof, but shall be subject and subordinate to the terms of this Trust Indenture. Neither a charter, Wet Lease nor ACMI contract shall be deemed to be a "lease" or "sublease", and the counterparty of a charter, Wet Lease or ACMI Contract shall not be deemed to be a lessee or sublessee for any purposes under this Trust Indenture. Any contract that is part of the United States Civil Reserve Air Fleet Program shall not be deemed to be a lease or sublease for any purposes under this Trust Indenture.

(c) Operation and Use. So long as the Aircraft, Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall not operate, use or locate the Aircraft, Airframe or any Engine, or allow the Aircraft, Airframe or any Engine to be operated, used or located, (i) in any area excluded from coverage by any insurance required by the terms of Section 4.06, except in the case of a requisition by the U.S. Government where the Owner obtains indemnity in lieu of such insurance from the U.S. Government, or insurance from the U.S. Government, against substantially the same risks and for at least the amounts of the insurance required by Section 4.06 covering such area, or (ii) in any recognized area of hostilities unless covered in accordance with Section 4.06 by war risk insurance, or in either case unless the Aircraft, the Airframe or any Engine is only temporarily operated, used or located in such area as a result of an emergency, equipment malfunction, navigational error, hijacking, weather condition or other similar unforeseen circumstance, so long as Owner diligently and in good faith proceeds to remove the Aircraft from such area. So long as the Aircraft, the Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall not permit such Aircraft, Airframe or any Engine, as the case may be, to be used, operated, maintained,


-33-

serviced, repaired or overhauled (x) in violation of any Law binding on or applicable to such Aircraft, Airframe or Engine or (y) in violation of any airworthiness certificate, license or registration of any Government Entity relating to the Aircraft, the Airframe or any Engine, except (i) immaterial or non-recurring violations with respect to which corrective measures are taken promptly by Owner or Permitted Lessee, as the case may be, upon discovery thereof, or (ii) to the extent the validity or application of any such Law or requirement relating to any such certificate, license or registration is being contested in good faith by Owner or Permitted Lessee in any reasonable manner which does not involve any material risk of the sale, forfeiture or loss of the Aircraft, Airframe or any Engine, any material risk of criminal liability or material civil penalty against Mortgagee or impair the Mortgagee's security interest in the Aircraft, Airframe or any Engine.

(d) Maintenance and Repair. So long as the Aircraft, Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall cause the Aircraft, Airframe and each Engine to be maintained, serviced, repaired and overhauled in accordance with (i) maintenance standards required by or substantially equivalent to those required by the FAA or the central aviation authority of Canada, France, Germany, Japan, the Netherlands or the United Kingdom for the Aircraft, Airframe and Engines, so as to (A) keep the Aircraft, the Airframe and each Engine in as good operating condition as on the Closing Date, ordinary wear and tear excepted, (B) keep the Aircraft in such operating condition as may be necessary to enable the applicable airworthiness certification of such Aircraft to be maintained under the regulations of the FAA or other Aviation Authority then having jurisdiction over the operation of the Aircraft, except during (x) temporary periods of storage in accordance with applicable regulations, (y) maintenance and modification permitted hereunder or
(z) periods when the FAA or such other Aviation Authority has revoked or suspended the airworthiness certificates for Similar Aircraft; and (ii) except during periods when a Permitted Lease is in effect, the same standards as Owner uses with respect to similar aircraft of similar size in its fleet operated by Owner in similar circumstances and, during any period in which a Permitted Lease is in effect, the same standards used by the Permitted Lessee with respect to similar aircraft of similar size in its fleet and operated by the Permitted Lessee in similar circumstances. Owner further agrees that the Aircraft, Airframe and Engines will be maintained, used, serviced, repaired, overhauled or inspected in compliance with applicable Laws with respect to the maintenance of the Aircraft and in compliance with each applicable airworthiness certificate, license and registration relating to the Aircraft, Airframe or any Engine issued by the Aviation Authority, other than minor or nonrecurring violations with respect to which corrective measures are taken upon discovery thereof and except to the extent Owner or Permitted Lessee is contesting in good faith the validity or application of any such Law or requirement relating to any such certificate, license or registration in any reasonable manner which does not create a material risk of sale, loss or forfeiture of the Aircraft, the Airframe or any Engine or the interest of


-34-

Mortgagee therein, or any material risk of criminal liability or material civil penalty against Mortgagee. The Owner shall maintain or cause to be maintained the Aircraft Documents in the English language.

(e) Registration. The Owner on or prior to the date of the Closing shall cause the Aircraft to be duly registered in its name under the Act and except as otherwise permitted by this Section 4.02(e) at all times thereafter shall cause the Aircraft to remain so registered. So long as no Special Default or Event of Default shall have occurred and be continuing, Owner may, by written notice to Mortgagee, request to change the country of registration of the Aircraft. Any such change in registration shall be effected only in compliance with, and subject to all of the conditions set forth in, Section 6.4.5 of the Participation Agreement. Unless the Trust Indenture has been discharged, Owner shall also cause the Trust Indenture to be duly recorded and at all times maintained of record as a first-priority perfected mortgage (subject to Permitted Liens) on the Aircraft, the Airframe and each of the Engines (except to the extent such perfection or priority cannot be maintained solely as a result of the failure by Mortgagee to execute and deliver any necessary documents).

(f) Markings. If permitted by applicable Law, on or reasonably promptly after the Closing Date, Owner will cause to be affixed to, and maintained in, the cockpit of the Airframe and on each Engine, in each case, in a clearly visible location, a placard of a reasonable size and shape bearing the legend: "Subject to a security interest in favor of Wilmington Trust Company, not in its individual capacity but solely as Mortgagee." Such placards may be removed temporarily, if necessary, in the course of maintenance of the Airframe or Engines. If any such placard is damaged or becomes illegible, Owner shall promptly replace it with a placard complying with the requirements of this Section.

SECTION 4.03. INSPECTION

(a) At all reasonable times, so long as the Aircraft is subject to the Lien of this Trust Indenture, Mortgagee and its authorized representatives (the "Inspecting Parties") may (not more than once every 12 months unless an Event of Default has occurred and is continuing then such inspection right shall not be so limited) inspect the Aircraft, Airframe and Engines (including without limitation, the Aircraft Documents) and any such Inspecting Party may make copies of such Aircraft Documents not reasonably deemed confidential by Owner or any Permitted Lessee.

(b) Any inspection of the Aircraft hereunder shall be limited to a visual, walk-around inspection and shall not include the opening of any panels, bays or other components


-35-

of the Aircraft, and no such inspection shall interfere with Owner's or any Permitted Lessee's maintenance and operation of the Aircraft, Airframe and Engines.

(c) With respect to such rights of inspection, Mortgagee shall not have any duty or liability to make, or any duty or liability by reason of not making, any such visit, inspection or survey.

(d) Each Inspecting Party shall bear its own expenses in connection with any such inspection (including the cost of any copies made in accordance with Section 4.03(a)).

SECTION 4.04. REPLACEMENT AND POOLING OF PARTS, ALTERATIONS, MODIFICATIONS AND ADDITIONS; SUBSTITUTION OF ENGINES

(a) Replacement of Parts. Except as otherwise provided herein, so long as the Aircraft, Airframe or Engine is subject to the Lien of this Trust Indenture, Owner, at its own cost and expense, will, or will cause a Permitted Lessee to, at its own cost and expense, promptly replace (or cause to be replaced) all Parts which may from time to time be incorporated or installed in, or attached to, the Aircraft, Airframe or any Engine and which may from time to time become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use for any reason whatsoever. In addition, Owner may, at its own cost and expense, or may permit a Permitted Lessee at its own cost and expense to, remove (or cause to be removed) in the ordinary course of maintenance, service, repair, overhaul or testing any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use; provided, however, that Owner, except as otherwise provided herein, at its own cost and expense, will, or will cause a Permitted Lessee at its own cost and expense to, replace such Parts as promptly as practicable. All replacement Parts shall be free and clear of all Liens, except for Permitted Liens and pooling arrangements to the extent permitted by Section 4.04(c) below (and except in the case of replacement property temporarily installed on an emergency basis) and shall be in good operating condition and have a value and utility not less than the value and utility of the Parts replaced (assuming such replaced Parts were in the condition required hereunder).

(b) Parts. Except as otherwise provided herein, any Part at any time removed from the Airframe or any Engine shall remain subject to the Lien of this Trust Indenture, no matter where located, until such time as such Part shall be replaced by a Part that has been incorporated or installed in, or attached to, such Airframe or any Engine and that meets the requirements for replacement Parts specified above. Immediately upon any replacement Part


-36-

becoming incorporated or installed in or attached to such Airframe or any Engine as provided in Section 4.04(a), without further act, (i) the replaced Part shall thereupon be free and clear of all rights of the Mortgagee and shall no longer be deemed a Part hereunder, and (ii) such replacement Part shall become subject to this Trust Indenture and be deemed part of such Airframe or any Engine, as the case may be, for all purposes hereof to the same extent as the Parts originally incorporated or installed in, or attached to, such Airframe or any Engine.

(c) Pooling of Parts. Any Part removed from the Aircraft, Airframe or an Engine may be subjected by the Owner or a Permitted Lessee to a normal pooling arrangement customary in the airline industry and entered into in the ordinary course of business of Owner or such Permitted Lessee, provided that the part replacing such removed Part shall be incorporated or installed in, or attached to, such Airframe or any Engine in accordance with Sections 4.04(a) and 4.04(b) as promptly as practicable after the removal of such removed Part. In addition, any replacement part when incorporated or installed in, or attached to, the Airframe or any Engine may be owned by any third party, subject to a normal pooling arrangement, so long as the Owner or a Permitted Lessee, at its own cost and expense, as promptly thereafter as reasonably possible, either (i) causes such replacement part to become subject to the Lien of this Trust Indenture, free and clear of all Liens except Permitted Liens, at which time such replacement part shall become a Part or (ii) replaces (or causes to be replaced) such replacement part by incorporating or installing in, or attaching to, the Aircraft, Airframe or any Engine a further replacement Part owned by the Owner free and clear of all Liens except Permitted Liens and which shall become subject to the Lien of this Trust Indenture in accordance with Section 4.04(b).

(d) Alterations, Modifications and Additions. The Owner shall, or shall cause a Permitted Lessee to, make (or cause to be made) such alterations and modifications in and additions to the Aircraft, Airframe and each Engine as may be required to be made from time to time to meet the applicable standards of the FAA or other Aviation Authority having jurisdiction over the operation of the Aircraft, to the extent made mandatory in respect of the Aircraft (a "Mandatory Modification"); provided, however, that the Owner or a Permitted Lessee may, in good faith and by appropriate procedure, contest the validity or application of any law, rule, regulation or order in any reasonable manner which does not materially adversely affect Mortgagee's interest in the Aircraft and does not involve any material risk of sale, forfeiture or loss of the Aircraft or the interest of Mortgagee therein, or any material risk of material civil penalty or any material risk of criminal liability being imposed on Mortgagee or the holder of any Equipment Note. In addition, the Owner, at its own expense, may, or may permit a Permitted Lessee at its own cost and expense to, from time to time make or cause to be made such alterations and modifications in and additions to the Airframe or any Engine (each an "Optional Modification") as the Owner or such Permitted Lessee may deem desirable in


-37-

the proper conduct of its business including, without limitation, removal of Parts which Owner deems are obsolete or no longer suitable or appropriate for use in the Aircraft, Airframe or such Engine; provided, however, that no such Optional Modification shall (i) materially diminish the fair market value, utility, or useful life of the Aircraft or any Engine below its fair market value, utility or useful life immediately prior to such Optional Modification (assuming the Aircraft or such Engine was in the condition required by the Trust Indenture immediately prior to such Optional Modification) or (ii) cause the Aircraft to cease to have the applicable standard certificate of airworthiness. All Parts incorporated or installed in or attached to any Airframe or any Engine as the result of any alteration, modification or addition effected by the Owner shall be free and clear of any Liens except Permitted Liens and become subject to the Lien of this Trust Indenture; provided that the Owner or any Permitted Lessee may, at any time so long as the Airframe or any Engine is subject to the Lien of this Trust Indenture, remove any such Part (such Part being referred to herein as a "Removable Part") if (i) such Part is in addition to, and not in replacement of or in substitution for, any Part originally incorporated or installed in, or attached to, such Airframe or any Engine at the time of delivery thereof hereunder or any Part in replacement of, or in substitution for, any such original Part, (ii) such Part is not required to be incorporated or installed in, or attached or added to, the Aircraft, Airframe or such Engine pursuant to the terms of Section 4.02(d) or the first sentence of this Section 4.04(d) and (iii) such Part can be removed from the Aircraft, Airframe or any Engine without materially diminishing the fair market value, utility or remaining useful life which such Aircraft, Airframe or Engine would have had at the time of removal had such removal not been effected by the Owner, assuming the Aircraft was otherwise maintained in the condition required by this Trust Indenture. Upon the removal by the Owner of any such Part as above provided, title thereto shall, without further act, be free and clear of all rights of the Mortgagee and such Part shall no longer be deemed a Part hereunder. Removable Parts may not be leased from or financed by third parties other than Mortgagee.

(e) Substitution of Engines. Upon the occurrence of an Event of Loss with respect to an Engine under circumstances in which an Event of Loss with respect to the Airframe has not occurred, Owner shall promptly (and in any event within 15 days after such occurrence) give the Mortgagee written notice of such Event of Loss. The Owner shall have the right at its option at any time, on at least 5 Business Days prior notice to the Mortgagee, to substitute, and if an Event of Loss shall have occurred with respect to an Engine under circumstances in which an Event of Loss with respect to the Airframe has not occurred, shall within 90 days of the occurrence of such Event of Loss substitute, a Replacement Engine for any Engine. In such event, immediately upon the effectiveness of such substitution and without further act, (i) the replaced Engine shall thereupon be free and clear of all rights of the Mortgagee and the Lien of this Trust Indenture and shall no longer be deemed an Engine hereunder and (ii) such Replacement Engine shall become subject to this Trust Indenture and


-38-

be deemed part of the Aircraft for all purposes hereof to the same extent as the replaced Engine. Such Replacement Engine shall be an engine manufactured by Engine Manufacturer that is the same model as the Engine to be replaced thereby, or an improved model, and that is suitable for installation and use on the Airframe, and that has a value, utility and remaining useful life (without regard to hours and cycles remaining until overhaul) at least equal to the Engine to be replaced thereby (assuming that such Engine had been maintained in accordance with this Trust Indenture). The Owner's right to make a replacement hereunder shall be subject to the fulfillment (which may be simultaneous with such replacement) of the following conditions precedent at the Owner's sole cost and expense, and the Mortgagee agrees to cooperate with the Owner to the extent necessary to enable it to timely satisfy such conditions:

(i) an executed counterpart of each of the following documents shall be delivered to the Mortgagee:

(A) a Trust Indenture Supplement covering the Replacement Engine, which shall have been duly filed for recordation pursuant to the Act or such other applicable law of the jurisdiction other than the United States in which the Aircraft of which such Engine is a part is registered in accordance with Section 4.02(e), as the case may be;

(B) a full warranty bill of sale (as to title), covering the Replacement Engine, executed by the former owner thereof in favor of the Owner (or, at the Owner's option, other evidence of the Owner's ownership of such Replacement Engine, reasonably satisfactory to the Mortgagee); and

(C) UCC financing statements covering the security interests created by this Trust Indenture (or any similar statements or other documents required to be filed or delivered pursuant to the laws of the jurisdiction in which such Aircraft may be registered) as are deemed necessary or desirable by counsel for the Mortgagee to protect the security interests of the Mortgagee, in the Replacement Engine;

(ii) the Owner shall cause to be delivered to the Mortgagee an opinion of counsel to the effect that the Lien of this Trust Indenture continues to be in full force and effect with respect to the Replacement Engine and such evidence of compliance with the insurance provisions of Section 4.06 with respect to such Replacement Engine as Mortgagee shall reasonably request;


-39-

(iii) the Owner shall have furnished to Mortgagee an opinion of Owner's aviation law counsel reasonably satisfactory to Mortgagee and addressed to Mortgagee as to the due filing for recordation of the Trust Indenture Supplement with respect to such Replacement Engine under the Act or such other applicable law of the jurisdiction other than the United States in which the Aircraft is registered in accordance with Section 4.02(e), as the case may be; and

(iv) the Owner shall have furnished to Mortgagee a certificate of a qualified aircraft engineer (who may be an employee of Owner) certifying that such Replacement Engine has a value and utility and remaining useful life (without regard to hours and cycles remaining until overhaul) at least equal to the Engine so replaced (assuming that such Engine had been maintained in accordance with this Trust Indenture).

Upon satisfaction of all conditions to such substitution, (x) the Mortgagee shall execute and deliver to the Owner such documents and instruments, prepared at the Owner's expense, as the Owner shall reasonably request to evidence the release of such replaced Engine from the Lien of this Trust Indenture, (y) the Mortgagee shall assign to the Owner all claims it may have against any other Person relating to any Event of Loss giving rise to such substitution and (z) the Owner shall receive all insurance proceeds (other than those reserved to others under Section 4.06(b)) and proceeds in respect of any Event of Loss giving rise to such replacement to the extent not previously applied to the purchase price of the Replacement Engine as provided in Section 4.05(d).

(d) Non-Insurance Payments Received on Account of an Event of Loss. Any amounts, other than insurance proceeds in respect of damage or loss not constituting an Event of Loss (the application of which is provided for in Annex
B), received at any time by Mortgagee or Owner from any Government Entity or any other Person in respect of any Event of Loss will be applied as follows:

(i) If such amounts are received with respect to the Airframe, and any Engine installed thereon at the time of such Event of Loss, upon compliance by Owner with the applicable terms of Section 4.05(c) with respect to the Event of Loss for which such amounts are received, such amounts shall be paid over to, or retained by, Owner;

Any amount referred to in this Section 4.05 or Section 4.06 which is payable or creditable to, or retainable by, the Owner shall not be paid or credited to, or retained by the Owner if at the time of such payment, credit or retention a Special Default or an Event of Default shall have occurred and be continuing, but shall be paid to and held by the Mortgagee as security for the obligations of the Owner under this Trust Indenture and the Operative Agreements, and at such time as there shall not be continuing any such Special Default or Event of Default such amount and any gain realized as a result of investments required to be made pursuant to
Section 6.06 shall to the extent not theretofore applied as provided herein, be paid over to the Owner.

SECTION 4.06. INSURANCE

(b) Insurance for Own Account. Nothing in Section 4.06 shall limit or prohibit (a) Owner from maintaining the policies of insurance required under Annex B with higher limits than those specified in Annex B, or (b) Mortgagee from obtaining insurance for its own account (and any proceeds payable under such separate insurance shall be payable as provided in the policy relating thereto); provided, however, that no insurance may be obtained or maintained that would limit or otherwise adversely affect the coverage of any insurance required to be obtained or maintained by Owner pursuant to this Section 4.06 and Annex B.

Mortgagee agrees to accept, in lieu of insurance against any risk with respect to the Aircraft described in Annex B, indemnification from, or insurance provided by, the U.S. Government, or upon the written consent of Mortgagee, other Government Entity, against such risk in an amount that, when added to the amount of insurance (including permitted self-insurance), if any, against such risk that Owner (or any Permitted Lessee) may continue to maintain, in accordance with this


-45-

Section 4.06, during the period of such requisition or transfer, shall be at least equal to the amount of insurance against such risk otherwise required by this Section 4.06.

(d) Application of Insurance Proceeds. As between Owner and Mortgagee, all insurance proceeds received as a result of the occurrence of an Event of Loss with respect to the Aircraft or any Engine under policies required to be maintained by Owner pursuant to this Section 4.06 will be applied in accordance with this Section 4.05(d). All proceeds of insurance required to be maintained by Owner, in accordance with Section 4.06 and Section B of Annex B, in respect of any property damage or loss not constituting an Event of Loss with respect to the Aircraft, Airframe or any Engine will be applied in payment (or to reimburse Owner) for repairs or for replacement property, and any balance remaining after such repairs or replacement with respect to such damage or loss shall be paid over to, or retained by, Owner.

SECTION 4.07. MERGER OF OWNER

(a) In General. Owner shall not consolidate with or merge into any other person under circumstances in which Owner is not the surviving corporation, or convey, transfer or lease in one or more transactions all or substantially all of its assets to any other person, unless:

(i) such person is organized, existing and in good standing under the Laws of the United States, any State of the United States or the District of Columbia and, upon consummation of such transaction, such person will be a U.S. Air Carrier;

(ii) such person executes and delivers to Mortgagee a duly authorized, legal, valid, binding and enforceable agreement, reasonably satisfactory in form and substance to Mortgagee, containing an effective assumption by such person of the due and punctual performance and observance of each covenant, agreement and condition in the Operative Agreements to be performed or observed by Owner;

(iii) such person makes such filings and recordings with the FAA pursuant to the Act as shall be necessary to evidence such consolidation or merger; and

(iv) immediately after giving effect to such consolidation or merger no Event of Default shall have occurred and be continuing.

(b) Effect of Merger. Upon any such consolidation or merger of Owner with or into, or the conveyance, transfer or lease by Owner of all or substantially all of its assets to, any Person in accordance with this Section 4.07, such Person will succeed to, and be substituted


-46-

for, and may exercise every right and power of, Owner under the Operative Agreements with the same effect as if such person had been named as "Owner" therein. No such consolidation or merger, or conveyance, transfer or lease, shall have the effect of releasing Owner or such Person from any of the obligations, liabilities, covenants or undertakings of Owner under the Trust Indenture.

SECTION 5.02. REMEDIES

(a) If an Event of Default shall have occurred and be continuing and so long as the same shall continue unremedied, then and in every such case the Mortgagee may exercise any or all of the rights and powers and pursue any and all of the remedies pursuant to this Article V and shall have and may exercise all of the rights and remedies of a secured party under the Uniform Commercial Code and may take possession of all or any part of the properties covered or intended to be covered by the Lien created hereby or pursuant hereto and may exclude the Owner and all persons claiming under it wholly or partly therefrom; provided that the Mortgagee shall give the Owner 20 days prior written notice of its intention to sell the Aircraft. Without limiting any of the foregoing, it is understood and agreed that the Mortgagee may exercise any right of sale of the Aircraft available to it, even though it shall not have taken possession of the Aircraft and shall not have possession thereof at the time of such sale.

(b) If an Event of Default shall have occurred and be continuing, then and in every such case the Mortgagee may (and shall, upon receipt of a written demand therefor from a Majority in Interest of Note Holders), at any time, by delivery of written notice or notices to the Owner, declare all the Equipment Notes to be due and payable, whereupon the unpaid Original Amount of all Equipment Notes then outstanding, together with accrued but unpaid interest thereon (without Make-Whole Amount) and other amounts due thereunder or otherwise payable hereunder, shall immediately become due and payable without presentment, demand, protest or notice, all of which are hereby waived; provided that if an Event of Default referred to in clause (e), (f) or (g) of Section 5.01 hereof shall have occurred, then and in every such case the unpaid Original Amount then outstanding, together with accrued but unpaid interest and all other amounts due hereunder and under the Equipment Notes shall immediately and without further act become due and payable without presentment, demand, protest or notice, all of which are hereby waived.

This Section 5.02(b), however, is subject to the condition that, if at any time after the Original Amount of the Equipment Notes shall have become so due and payable, and before any judgment or decree for the payment of the money so due, or any thereof, shall be entered, all overdue payments of interest upon the Equipment Notes and all other amounts payable hereunder or under the Equipment Notes (except the Original Amount of the Equipment Notes which by such declaration shall have become payable) shall have been duly paid, and every other Default and Event of Default with respect to any covenant or provision of this Trust Indenture shall have been cured, then and in every such case a Majority in Interest of Note Holders may (but shall not be obligated to), by written instrument filed with the Mortgagee, rescind and annul the Mortgagee's declaration (or such automatic acceleration) and its


-49-

consequences; but no such rescission or annulment shall extend to or affect any subsequent Default or Event of Default or impair any right consequent thereon.

(c) The Note Holders shall be entitled, at any sale pursuant to this
Section 5.02, to credit against any purchase price bid at such sale by such holder all or any part of the unpaid obligations owing to such Note Holder and secured by the Lien of this Trust Indenture (only to the extent that such purchase price would have been paid by such Note Holder pursuant to Article III hereof if such purchase price were paid in cash and the foregoing provisions of this subsection (c) were not given effect).

(d) In the event of any sale of the Collateral, or any part thereof, pursuant to any judgment or decree of any court or otherwise in connection with the enforcement of any of the terms of this Trust Indenture, the unpaid Original Amount of all Equipment Notes then outstanding, together with accrued interest thereon (without Make-Whole Amount), and other amounts due thereunder, shall immediately become due and payable without presentment, demand, protest or notice, all of which are hereby waived.

(e) Notwithstanding anything contained herein, so long as the Pass Through Trustee under any Pass Through Trust Agreement (or its designee) is a Note Holder, the Mortgagee will not be authorized or empowered to acquire title to any Collateral or take any action with respect to any Collateral so acquired by it if such acquisition or action would cause any Trust to fail to qualify as a "grantor trust" for federal income tax purposes.

SECTION 5.03. RETURN OF AIRCRAFT, ETC.

(a) If an Event of Default shall have occurred and be continuing and the Equipment Notes have been accelerated, at the request of the Mortgagee, the Owner shall promptly execute and deliver to the Mortgagee such instruments of title and other documents as the Mortgagee may deem necessary or advisable to enable the Mortgagee or an agent or representative designated by the Mortgagee, at such time or times and place or places as the Mortgagee may specify, to obtain possession of all or any part of the Collateral to which the Mortgagee shall at the time be entitled hereunder. If the Owner shall for any reason fail to execute and deliver such instruments and documents after such request by the Mortgagee, the Mortgagee may (i) obtain a judgment conferring on the Mortgagee the right to immediate possession and requiring the Owner to execute and deliver such instruments and documents to the Mortgagee, to the entry of which judgment the Owner hereby specifically consents to the fullest extent permitted by Law, and (ii) pursue all or part of such Collateral wherever it may be found and may enter any of the premises of Owner wherever such Collateral may be or be supposed to be and search for such Collateral and take possession of and remove such Collateral.


-50-

All other rights, powers, duties and obligations conferred or imposed upon any additional or separate trustee shall be exercised or performed by the Mortgagee and such additional or separate trustee jointly except to the extent that applicable Law of any jurisdiction in which any particular act is to be performed renders the Mortgagee incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations (including the holding of title to all or part of the Collateral in any such jurisdiction) shall be exercised and performed by such additional or separate trustee. No additional or separate trustee shall take any discretionary action except on the instructions of the Mortgagee or a Majority in Interest of Note Holders. No trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder, except that the Mortgagee shall be liable for the consequences of its lack of reasonable care in selecting, and the Mortgagee's own actions in acting with, any additional or separate trustee.

Ladies and Gentlemen:

We have examined a copy of the Registration Statement on Form S-4 (No. 333- ) (the "Registration Statement"), filed by Atlas Air, Inc. (the "Company") with the Securities and Exchange Commission (the "Commission") on May 4, 2000 and relating to the registration pursuant to the provisions of the Securities Act of 1933, as amended ( the "Act"), of Pass Through Certificates, Series 2000-1 in the principal amount of $217,317,000 (the "New Certificates"). The New Certificates, which upon the effectiveness of the Registration Statement will be registered under the Act, will be issued in exchange for a like principal amount of the outstanding Pass Through Certificates, Series 2000-1 (the "Old Certificates"), which are not registered under the Act. Each of the New Certificates represents a fractional undivided interest in one of the three Atlas Air 2000-1 Pass Through Trusts (the "Trusts") and will be issued pursuant to three separate Pass Through Trust Agreements (collectively, the "Pass Through Trust Agreements") dated as of January 28, 2000, between the Company and Wilmington Trust Company. In rendering this opinion, we have reviewed such documents and made such investigations as we have deemed appropriate.


-2-

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that when the New Certificates have been duly executed and authenticated in accordance with the Pass Through Trust Agreements, and duly issued and delivered by the Trusts in exchange for an equal principal amount of Old Certificates pursuant to the terms of the Registration Rights Agreement filed as an exhibit to the Registration Statement, the New Certificates will be legal, valid, binding and enforceable obligations of the applicable Trust, entitled to the benefits of the applicable Pass Through Trust Agreement, subject to applicable bankruptcy, insolvency and similar laws affecting creditors' rights generally and to general principles of equity.

We are members of the bar of the State of New York and do not purport to be experts in, or to express any opinion concerning, the laws of any jurisdiction other than the law of the State of New York, the Delaware General Corporation Law and the federal laws of the United States of America.

Neither this opinion nor any part hereof may be delivered to, used or relied upon by any person other than you without our prior written consent.

We hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement and to the reference to our firm under the caption "Legal Matters" in the Registration Statement and related prospectus. Our consent to such reference does not constitute a consent under Section 7 of the Securities Act, and in consenting to such reference we have not certified any part of the Registration Statement and do not otherwise come within the categories of persons whose consent is required under said
Section 7 or under the rules and regulations of the Commission thereunder.

Very truly yours,

2. EMPLOYMENT AND OBLIGATIONS OF EMPLOYEE

Atlas and Employee agree to the following rights, obligations and duties with respect to employment:

2.1 Employment. During the Employment Period, Atlas agrees to employ the Employee as Executive Vice President of Atlas. Employee shall not be entitled to any additional compensation for serving in any other office for Atlas or any subsidiary or affiliate of Atlas.

3.1 Base Annual Salary. Atlas will pay Employee a base annual salary (the "Base Annual Salary") of no less than $250,000 per annum, payable in semi-monthly installments, which amount shall increase to an amount not less than $325,000 upon (i) the consummation of an acquisition by Atlas of an entity for an acquisition price of in excess of $500,000,000 or (ii) Employee's establishing a residence, at the request of the chief executive officer, in the Seattle, Washington or White Plains, New York area.

-8-

4. TERMINATION OF EMPLOYMENT PERIOD

The Employment Period shall terminate under the following terms and conditions:

4.1 At Will Arrangement. Atlas may terminate the Employment Period upon written notice to the Employee at any time and for any reason. Both Atlas and Employee expressly understand and agree that the employment relationship is at-will. Atlas is entitled to sever the employment relationship for any reason.

4.2 Rights Following Termination.

(a) If the Employment Period is terminated by Atlas for reasons other than Cause or if the Employment Period is terminated by the Employee for Good Reason, the Employee shall be entitled to receive: (i) in a single lump sum payment within 10 business days after such termination, an amount equal to $325,000, (ii) an amount equal to $650,000, payable quarterly, in advance, over the twenty-four month period commencing twelve months following Employee's termination, (iii) an amount equal to $250,000 payable quarterly, in advance, over the twelve month period commencing thirty-six months following Employee's


-9-

termination, and (iv) continued coverage and rights and benefits available under the employee benefit programs of Atlas as provided in Section 3.3 above for a period of three years from the date of termination; provided, however, that any such continued coverage shall be offset by comparable coverage provided to Employee in connection with subsequent employment, and to the extent Atlas is unable to continue such coverage, Atlas shall provide the Employee with economically equivalent benefits determined on an after-tax basis.

(b) Upon the death or Permanent Disability of the Employee, the Employment Period shall terminate and the Employee's Base Annual Salary which is accrued but unpaid as of the date of such death or Permanent Disability shall be paid to the Employee or his personal representative.

(c) If the Employment Period is terminated by Atlas for Cause or by the Employee for other than Good Reason, the Employee shall be entitled to receive his Base Annual Salary which is accrued but unpaid as of the date of termination.

(d) If Employee's employment with Atlas is terminated as a result of the failure of Atlas or Employee to renew this Employment Agreement by giving the notice called for in


-10-

Section 1.2 hereof, Employee shall be deemed to have been terminated by Atlas without "Cause" for the purpose of (i) the vesting of Employee's outstanding options and restricted stock awards and (ii) the severance payments and benefit coverage referred to in Section 4.2 (a).

4.3 Non-Competition Provision. Employee covenants and agrees that he will not, at any time before five years after his termination of employment with Atlas, reveal, divulge or make known to any third party any confidential or proprietary records, data, trade secrets, pricing policies, strategy, rate structure, personnel policy, management methods, financial reports, methods or practice of obtaining or doing business, or any other confidential or proprietary information of Atlas or any of its affiliates which is not in the public domain. In addition, Employee agrees that, at no time before three years after his termination of employment with Atlas, will he engage in any of the following activities directly or indirectly, for any reason, whether for his own account or for the account of any other person, firm, corporation or other organization:

(a) solicit, employ or otherwise interfere with any of Atlas' contracts or relationships with any client, employee, officer, director or any independent contractor whether the person is employed by or associated with Atlas on the date of this Agreement or at any time thereafter; or


-11-

(b) solicit, accept or otherwise interfere with any of Atlas' contracts or relationships with any independent contractor, customer, client or supplier, or any person who is a bona fide prospective independent contractor, customer, client or supplier of Atlas;

(c) accept employment with, or give advice to, any air cargo carrier or an air cargo division or affiliate of any other airline.

The parties agree and intend that breach of this non-competition clause shall subject Employee to the full measure of contract and equitable damages including punitive damages.

5. EXCISE TAX GROSS-UP

5.1 (a) Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any payment or distribution made, or benefit provided, by Atlas to or for the benefit of the Employee (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, but determined without regard to any additional payments required under this Section 5.1) (a "Payment") would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended and then in effect (the "Code") (or any similar excise tax) or any


-12-

interest or penalties are incurred by the Employee with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the "Excise Tax"), then the Employee shall be entitled to receive an additional payment (a "Gross-Up Payment") in an amount such that after payment by the Employee of all Federal, state, local or other taxes (including any interest or penalties imposed with respect to any such taxes), including, without limitation, any such income taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the Employee retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments.

(b) Subject to the provisions of paragraph (c) of this Section 5.1, all determinations required to be made under this Section 5.1, including whether and when a Gross-Up Payment is required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by Arthur Andersen (the "Accounting Firm") which shall provide detailed supporting calculations both to Atlas and the Employee within 20 calendar days of the receipt of written notice from the Employee that there has been a Payment,


-13-

or such earlier time as is requested by Atlas. In the event that the Accounting Firm is serving as accountant or auditor for the individual, entity or group effecting the change in control, the Employee shall have the right by written notice to Atlas to appoint another nationally recognized accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall be borne solely by Atlas and shall be paid by Atlas upon demand of the Employee as incurred or billed by the Accounting Firm. Any Gross-Up Payment, as determined pursuant to this Section 5.1, shall be paid by Atlas to the Employee within five days of the receipt of the Accounting Firm's determination. If the Accounting Firm determines that no Excise Tax is payable by the Employee, it shall furnish the Employee with an unqualified written opinion in form and substance satisfactory to the Employee that failure to report the Excise Tax on the Employee's applicable federal income tax return would not result in the imposition of a negligence or similar penalty. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by Atlas should have been made ("Underpayment"),


-14-

consistent with the calculations required to be made hereunder. In the event that Atlas exhausts its remedies described in paragraph (c) of this Section 5.1 and the Employee thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be paid by Atlas to or for the benefit of the Employee within five days of the receipt of the Accounting Firm's determination. All determinations made by the Accounting Firm in connection with any Gross-Up Payment or Underpayment shall be final and binding upon Atlas and the Employee.

(c) The Employee shall notify Atlas in writing of any claim asserted in writing by the Internal Revenue Service to the Employee that, if successful, would require the payment by Atlas of the Gross-Up Payment. Such notification shall be given as soon as practicable but not later than 60 days after the Employee is informed in writing of such claim and shall apprise Atlas of the nature of such claim and the date on which such claim is requested to be paid. The Employee shall not pay such claim prior to the expiration of the 30-day period following the date on which it gives such notice to Atlas (or such shorter period ending on the date that any payment of taxes


-15-

with respect to such claim is due). If Atlas notifies the Employee in writing prior to the expiration of such period that it desires to contest such claim, the Employee shall at Atlas' expense:

(i) give Atlas any information reasonably requested by Atlas relating to such claim,

(ii) take such action in connection with contesting such claim as Atlas shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by Atlas,

(iii) cooperate with Atlas in good faith in order effectively to contest such claim, and

(iv) permit Atlas to participate in any proceedings relating to such claim;

provided, however, that Atlas shall bear and pay directly as incurred all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold the Employee harmless, on an after-tax basis, for any Excise Tax or any Federal, state, local or other income or other tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Section 5.1, Atlas shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forego any and all administrative


-16-

appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct the Employee to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and the Employee agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as Atlas shall determine; provided, however, that if Atlas directs the Employee to pay such claim and sue for a refund, Atlas shall advance the amount of such payment to the Employee, on an interest-free basis and shall indemnify and hold the Employee harmless, on an after-tax basis, from any Excise Tax or Federal, state, local or other income or other tax (including interest or penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance; and further provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of the Employee with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, Atlas' control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and the Employee shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.


-17-

(d) If, after the receipt by the Employee of an amount advanced by Atlas pursuant to paragraph (c) of this Section 5.1, the Employee becomes entitled to receive any refund with respect to such claim, the Employee shall (subject to Atlas' complying with the requirements of paragraph (ii) of this
Section 5.1) promptly pay to Atlas the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto) upon receipt thereof. If, after the receipt by the Employee of an amount advanced by Atlas pursuant to paragraph (c) of this Section 5.1, a determination is made that the Employee shall not be entitled to any refund with respect to such claim and Atlas does not notify the Employee in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid.


-18-

6. CHOICE OF LAW

This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without reference to principles of conflict of laws.

7. SEVERABILITY AND ENFORCEABILITY

It is expressly acknowledged and agreed that the covenants and provisions hereof are separable; that the enforceability of one covenant or provision shall in no event affect the full enforceability of any other covenant or provision herein. Further, it is agreed that, in the event any covenant or provision of this Agreement is found by any court of competent jurisdiction to be unenforceable, illegal or invalid, such invalidity, illegality or unenforceability shall not affect any other term or condition of this Agreement. Rather, the Agreement shall be construed as if such invalid or illegal or unenforceable term or condition had never been contained herein. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement.


-19-

8. MISCELLANEOUS

8.1 No Mitigation. The amounts to be paid Employee are net to Employee, without any reduction or duty to mitigate, except for taxes, other governmental charges or amounts owed to Atlas by Employee.

8.2 Pro-Ration. In the event the Employment Period is terminated in the middle of any calendar month, the amount due for such month shall be pro-rated on a daily basis.

8.3 No Waiver Except in Writing. No waiver or modification of this Agreement or any of the terms and conditions set forth herein shall be effective unless submitted to a writing duly executed by the parties.

8.4 Successors and Assigns. This Agreement shall be binding on Atlas and any successor thereto, whether by reason of merger, consolidation or otherwise. The duties and obligations of Employee may not be assigned by Employee.

8.5 Confidentiality of Terms. Atlas and Employee agree that the terms and conditions of this Agreement are confidential and that they will not disclose the terms of this Agreement to any third parties, other than the Employee's


-20-

spouse, their attorneys, auditors, accountants or as required by law or as may be necessary to enforce this Agreement.

8.6 Full Understanding. Employee declares and represents that he has carefully read and fully understands the terms of this Agreement, has had the opportunity to obtain advice and assistance of counsel with respect thereto, and knowingly and of his own free will, without any duress, being fully informed and after due deliberation, voluntarily accepts the terms of this Agreement.

8.7 Entire Agreement. This Agreement sets forth the entire agreement and understanding between the parties with respect to the subject matter hereof and supersedes all prior agreements, arrangements, and understandings between the parties with respect to the subject matter hereof.

Promptly after receipt by Administrative Agent of a Notice of Borrowing pursuant to subsection 2.1B (or telephonic notice in lieu thereof), Administrative Agent shall notify each Lender of the proposed borrowing. Each Lender shall make the amount of its Loan available to Administrative Agent not later than 12:00 Noon (New York time) on the applicable Funding Date, in each case in same day funds in Dollars, at the Funding and Payment Office.

Unless Administrative Agent shall have been notified by any Lender prior to the Funding Date for any Loans that such Lender does not intend to make available to Administrative Agent the amount of such Lender's Loan requested on such Funding Date, Administrative Agent may assume that such Lender has made such amount available to Administrative Agent on such Funding Date and Administrative Agent may, in its sole discretion, but shall not be obligated to, make available to Company a corresponding amount on such Funding Date. If such corresponding amount is not in fact made available to Administrative Agent by such Lender, Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender together with interest thereon, for each day from such Funding Date until the date such amount is paid to Administrative Agent, at the customary rate set by Administrative Agent for the correction of errors among banks for three Business Days and thereafter at the Base Rate. If such Lender does not pay such corresponding amount forthwith upon Administrative Agent's demand therefor, Administrative Agent shall promptly notify Company and Company shall immediately pay such corresponding amount to Administrative Agent together with interest thereon, for each day from such Funding Date until the date such amount is paid to Administrative Agent, at the rate payable under this Agreement for Base Rate Loans. Nothing in this subsection 2.1C shall be deemed to relieve any Lender from its obligation to fulfill its Commitments hereunder or to prejudice any rights that Company may have against any Lender as a result of any default by such Lender hereunder.

2.2 INTEREST ON THE LOANS.

A. RATE OF INTEREST. Subject to the provisions of subsections 2.6 and 2.7, each Loan shall bear interest on the unpaid principal amount thereof from the date made through maturity (whether by acceleration or otherwise) at a rate determined by reference to the Base Rate or the Adjusted Eurodollar Rate, as the case may be. The applicable basis for determining the rate of interest with respect to any Loan shall be selected by Company initially at the time a Notice of Borrowing is given with respect to such Loan pursuant to subsection 2.1B. The basis for determining the interest rate with respect to any Loan may be changed from time to time pursuant to subsection 2.2D. If on any day a Loan is outstanding with respect to which notice has not been delivered to Administrative Agent in accordance with the terms of this Agreement specifying the applicable basis for determining the rate of interest, then for that day that Loan shall bear interest determined by reference to the Base Rate.

Subject to the provisions of subsections 2.2E and 2.7, each Loan shall bear interest through maturity as follows:

(i) if a Base Rate Loan, then at the sum of the Base Rate plus the Applicable Margin per annum; or

(ii) if a Eurodollar Rate Loan, then at the sum of the Adjusted Eurodollar Rate plus the Applicable Margin per annum.

-34-

The "APPLICABLE MARGIN" for each Base Rate Loan and Eurodollar Rate Loan shall be the percentage set forth below for that type of Loan for the periods set forth below.

                                              APPLICABLE MARGIN
                                              --------------------------

TIME PERIOD                                   LOAN            RATE LOAN
                                              ---------       ----------
From the Second Amendment Effective Date      1.00%           2.00%
through the Fourth Restatement Date

From the Fourth Restatement Date and          0.75%           1.75%
Thereafter

Notwithstanding the foregoing, the Applicable Margin shall be reduced in an amount equal to the applicable Pricing Reduction effective from the date following the delivery by Company to Administrative Agent of a Pricing Certificate through the date a subsequent Pricing Certificate is required to be delivered. If Company fails to deliver a Pricing Certificate or delivers an incorrect Pricing Certificate, no Pricing Reduction shall be effective until Company delivers a correct Pricing Certificate.

B. INTEREST PERIODS. In connection with each Eurodollar Rate Loan, Company may, pursuant to the applicable Notice of Borrowing or Notice of Conversion/Continuation, as the case may be, select an interest period (each an "INTEREST PERIOD") to be applicable to such Loan, which Interest Period shall be, at Company's option, either a one, two, three or six month period; provided that:

(i) the initial Interest Period for any Eurodollar Rate Loan shall commence on the Funding Date in respect of such Loan, in the case of a Loan initially made as a Eurodollar Rate Loan, or on the date specified in the applicable Notice of Conversion/Continuation, in the case of a Loan converted to a Eurodollar Rate Loan;

(ii) in the case of immediately successive Interest Periods applicable to a Eurodollar Rate Loan continued as such pursuant to a Notice of Conversion/Continuation, each successive Interest Period shall commence on the day on which the next preceding Interest Period expires;

(iii) if an Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day; provided that, if any Interest Period would otherwise expire on a day that is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the next preceding Business Day;

(iv) any Interest Period that begins on the last Business Day of a calendar month (or on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period) shall, subject to clause (v) of this subsection 2.2B, end on the last Business Day of a calendar month;

-35-

(v) no Interest Period with respect to any portion of the Loans shall extend beyond the Final Scheduled Maturity Date.

(vi) no Interest Period with respect to any portion of the Loans shall extend beyond a date on which Company is required to make a scheduled payment of principal of the Loans unless the sum of (a) the aggregate principal amount of Loans that are Base Rate Loans plus (b) the aggregate principal amount of Loans that are Eurodollar Rate Loans with Interest Periods expiring on or before such date equals or exceeds the principal amount required to be paid on the Loans on such date;

(vii) there shall be no more than twelve Interest Periods outstanding at any time;

(viii) in the event Company fails to specify an Interest Period for any Eurodollar Rate Loan in the applicable Notice of Borrowing or Notice of Conversion/Continuation, Company shall be deemed to have selected an Interest Period of one month; and

(ix) prior to the date that is three months from the Fourth Restatement Date, no Interest Period with respect to any portion of the Loans shall exceed one month.

C. INTEREST PAYMENTS. Subject to the provisions of subsection 2.2E, interest on each Loan shall be payable in arrears on and to each Interest Payment Date applicable to that Loan, upon any prepayment of that Loan (to the extent accrued on the amount being prepaid) and at maturity (including final maturity).

D. CONVERSION OR CONTINUATION. Subject to the provisions of subsection 2.6, Company shall have the option (i) to convert at any time all or any part of its outstanding Loans equal to $3,000,000 and integral multiples of $100,000 in excess of that amount from Loans bearing interest at a rate determined by reference to one basis to Loans bearing interest at a rate determined by reference to an alternative basis or (ii) upon the expiration of any Interest Period applicable to a Eurodollar Rate Loan, to continue all or any portion of such Loan equal to $3,000,000 and integral multiples of $100,000 in excess of that amount as a Eurodollar Rate Loan; provided, however, that a Eurodollar Rate Loan may only be converted into a Base Rate Loan on the expiration date of an Interest Period applicable thereto.

Company shall deliver a Notice of Conversion/Continuation to Administrative Agent no later than 12:00 Noon (New York time) at least one Business Day in advance of the proposed conversion date (in the case of a conversion to a Base Rate Loan) and at least three Business Days in advance of the proposed conversion/continuation date (in the case of a conversion to, or a continuation of, a Eurodollar Rate Loan). A Notice of Conversion/Continuation shall specify (i) the proposed conversion/continuation date (which shall be a Business Day), (ii) the amount and type of the Loan to be converted/continued,
(iii) the nature of the proposed conversion/continuation, (iv) in the case of a conversion to, or a continuation of, a Eurodollar Rate Loan, the requested Interest Period, and (v) in the case of a conversion to, or

-36-

a continuation of, a Eurodollar Rate Loan, that no Potential Event of Default or Event of Default has occurred and is continuing. In lieu of delivering the above-described Notice of Conversion/Continuation, Company may give Administrative Agent telephonic notice by the required time of any proposed conversion/continuation under this subsection 2.2D; provided that such notice shall be promptly confirmed in writing by delivery of a Notice of Conversion/Continuation to Administrative Agent on or before the proposed conversion/continuation date.

Neither Administrative Agent nor any Lender shall incur any liability to Company in acting upon any telephonic notice referred to above that Administrative Agent believes in good faith to have been given by a duly authorized officer or other person authorized to act on behalf of Company or for otherwise acting in good faith under this subsection 2.2D, and upon conversion or continuation of the applicable basis for determining the interest rate with respect to any Loans in accordance with this Agreement pursuant to any such telephonic notice Company shall have effected a conversion or continuation, as the case may be, hereunder.

Except as otherwise provided in subsections 2.6B, 2.6C and 2.6G, a Notice of Conversion/Continuation for conversion to, or continuation of, a Eurodollar Rate Loan (or telephonic notice in lieu thereof) shall be irrevocable on and after the related Interest Rate Determination Date, and Company shall be bound to effect a conversion or continuation in accordance therewith.

E. DEFAULT RATE. Upon the occurrence and during the continuation of any Event of Default, the outstanding principal amount of all Loans and, to the extent permitted by applicable law, any interest payments thereon not paid when due and any fees and other amounts then due and payable hereunder, shall thereafter bear interest (including post-petition interest in any proceeding under the Bankruptcy Code or other applicable bankruptcy laws) payable upon demand at a rate that is 2% per annum in excess of the interest rate otherwise payable under this Agreement with respect to the applicable Loans (or, in the case of any such fees and other amounts, at a rate which is 2% per annum in excess of the interest rate otherwise payable under this Agreement for Base Rate Loans) ; provided that, in the case of Eurodollar Rate Loans, upon the expiration of the Interest Period in effect at the time any such increase in interest rate is effective such Eurodollar Rate Loans shall thereupon become Base Rate Loans and shall thereafter bear interest payable upon demand at a rate which is 2% per annum in excess of the interest rate otherwise payable under this Agreement for Base Rate Loans. Payment or acceptance of the increased rates of interest provided for in this subsection 2.2E is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Administrative Agent or any Lender.

F. COMPUTATION OF INTEREST. Interest on each Loan shall be computed on the basis of a 360-day year, in each case for the actual number of days elapsed in the period

-37-

during which it accrues. In computing interest on any Loan, the date of the making of such Loan or the first day of an Interest Period applicable to such Loan or, with respect to a Base Rate Loan being converted from a Eurodollar Rate Loan, the date of conversion of such Eurodollar Rate Loan to such Base Rate Loan, as the case may be, shall be included, and the date of payment of such Loan or the expiration date of an Interest Period applicable to such Loan or, with respect to a Base Rate Loan being converted to a Eurodollar Rate Loan, the date of conversion of such Base Rate Loan to such Eurodollar Rate Loan, as the case may be, shall be excluded; provided that if a Loan is repaid on the same day on which it is made, one day's interest shall be paid on that Loan.

2.3 FEES.

A. COMMITMENT FEES. Company agrees to pay to Administrative Agent, for distribution to each Lender in proportion to that Lender's Pro Rata Share, commitment fees for the period from and including the Fourth Restatement Date to and excluding the Revolving Loan Commitment Termination Date equal to the average of the daily excess of the Revolving Loan Commitments over the aggregate principal amount of Loans outstanding multiplied by (y) if a Pricing Reduction is not then in effect, 0.50% per annum or (z) if a Pricing Reduction is then in effect, 0.375% per annum, such commitment fees to be calculated on the basis of a 360-day year and the actual number of days elapsed and to be payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year, commencing on the first such date to occur after the Fourth Restatement Date, and on the Revolving Loan Commitment Termination Date.

All payments by Company of principal, interest, fees and other Obligations hereunder and under the Notes shall be made in Dollars in same day funds, without defense, set-off or counterclaim, free of any restriction or condition, and delivered to Administrative Agent not later than 12:00 Noon (New York time) on the date due at the Funding and Payment Office for the account of Lenders; funds received by Administrative Agent after that time on such due date shall be deemed to have been paid by Company on the next succeeding Business Day. Company hereby authorizes Administrative Agent to charge its

-44-

accounts with Administrative Agent in order to cause timely payment to be made to Administrative Agent of all principal, interest, fees and expenses due hereunder (subject to sufficient funds being available in its accounts for that purpose).

(ii) Application of Payments to Principal and Interest. All payments in respect of the principal amount of any Loan shall include payment of accrued interest on the principal amount being repaid or prepaid, and all such payments shall be applied to the payment of interest before application to principal.

(iii) Apportionment of Payments. Aggregate principal and interest payments in respect of Loans shall be apportioned among all outstanding Loans to which such payments relate, in each case proportionately to Lenders' respective Pro Rata Shares. Administrative Agent shall promptly distribute to each Lender, at its primary address set forth below its name on the appropriate signature page hereof or at such other address as such Lender may request, its Pro Rata Share of all such payments received by Administrative Agent and the commitment fees of such Lender when received by Administrative Agent pursuant to subsection 2.3. Notwithstanding the foregoing provisions of this subsection 2.4C(iii), if, pursuant to the provisions of subsection 2.6C, any Notice of Conversion/Continuation is withdrawn as to any Affected Lender or if any Affected Lender makes Base Rate Loans in lieu of its Pro Rata Share of any Eurodollar Rate Loans, Administrative Agent shall give effect thereto in apportioning payments received thereafter.

(iv) Payments on Business Days. Whenever any payment to be made hereunder shall be stated to be due on a day that is not a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall be included in the computation of the payment of interest hereunder or of the commitment fees hereunder, as the case may be.

(v) Notation of Payment. Each Lender agrees that before disposing of any Note held by it, or any part thereof (other than by granting participations therein), that Lender will make a notation thereon of all Loans evidenced by that Note and all principal payments previously made thereon and of the date to which interest thereon has been paid; provided that the failure to make (or any error in the making of) a notation of any Loan made under such Note shall not limit or otherwise affect the obligations of Company hereunder or under such Note with respect to any Loan or any payments of principal or interest on such Note.

2.5 USE OF PROCEEDS.

A. EXISTING AIRCRAFT EXTENDED LOANS. The proceeds of the Existing Aircraft Extended Loans were used to finance the purchase and renovation of the Existing Aircraft as shown on Schedule 1.1 annexed hereto.

-45-

B. NEW AIRCRAFT LOANS. The proceeds of New Aircraft Loans shall be applied to finance (i) the purchase of an Eligible Aircraft pursuant to a Purchase Agreement in an amount up to the lesser of the purchase price of such Eligible Aircraft and 80% of the Appraised Value of such Eligible Aircraft (but without giving effect to any contemplated modifications) and/or (ii) the cost of making a Financed Aircraft usable by Company as a cargo aircraft by paying for those modifications identified in any Modification Agreement and any BFE Agreement (but not for maintenance costs) in an amount that when added to the amount financed in (i) does not exceed 80% the Appraised Value of such modified Eligible Aircraft; provided that the final Revolving Loan to finance the modification of such Eligible Aircraft may be in an amount equal to the lesser of (x) 100% of the costs of modification associated with such final Revolving Loan and (y) an amount which, when added to all other Revolving Loans made with respect to such Eligible Aircraft, does not exceed 80% of the Appraised Value of such Eligible Aircraft after giving effect to the completion of modification.

C. MARGIN REGULATIONS. No portion of the proceeds of any borrowing under this Agreement shall be used by Company or any of its Subsidiaries in any manner that might cause the borrowing or the application of such proceeds to violate Regulation U, Regulation T or Regulation X of the Board of Governors of the Federal Reserve System or any other regulation of such Board or to violate the Exchange Act, in each case as in effect on the date or dates of such borrowing and such use of proceeds.

2.6 SPECIAL PROVISIONS GOVERNING EURODOLLAR RATE LOANS.

Notwithstanding any other provision of this Agreement to the contrary, the following provisions shall govern with respect to Eurodollar Rate Loans as to the matters covered:

A. DETERMINATION OF APPLICABLE INTEREST RATE. As soon as practicable after 10:00 A.M. (New York time) on each Interest Rate Determination Date, Administrative Agent shall determine (which determination shall, absent manifest error, be final, conclusive and binding upon all parties) the interest rate that shall apply to the Eurodollar Rate Loans for which an interest rate is then being determined for the applicable Interest Period and shall promptly give notice thereof (in writing or by telephone confirmed in writing) to Company and each Lender.

B. INABILITY TO DETERMINE APPLICABLE INTEREST RATE. In the event that Administrative Agent shall have determined (which determination shall be final and conclusive and binding upon all parties hereto), on any Interest Rate Determination Date with respect to any Eurodollar Rate Loans, that by reason of circumstances affecting the interbank Eurodollar market adequate and fair means do not exist for ascertaining the interest rate applicable to such Loans on the basis provided for in the definition of Adjusted Eurodollar Rate, Administrative Agent shall on such date give notice (by telefacsimile or by telephone confirmed in writing) to Company and each Lender of such determination, whereupon (i) no Loans may be made as, or converted to, Eurodollar Rate Loans until such time as

-46-

Administrative Agent notifies Company and Lenders that the circumstances giving rise to such notice no longer exist and (ii) any Notice of Borrowing or Notice of Conversion/Continuation given by Company with respect to the Loans in respect of which such determination was made shall be deemed to be rescinded by Company.

C. ILLEGALITY OR IMPRACTICABILITY OF EURODOLLAR RATE LOANS. In the event that on any date any Lender shall have determined (which determination shall be final and conclusive and binding upon all parties hereto but shall be made only after consultation with Company and Administrative Agent) that the making, maintaining or continuation of its Eurodollar Rate Loans (i) has become unlawful as a result of compliance by such Lender in good faith with any law, treaty, governmental rule, regulation, guideline or order (or would conflict with any such treaty, governmental rule, regulation, guideline or order not having the force of law even though the failure to comply therewith would not be unlawful) or (ii) has become impracticable, or would cause such Lender material hardship, as a result of contingencies occurring after the date of this Agreement which materially and adversely affect the interbank Eurodollar market or the position of such Lender in that market, then, and in any such event, such Lender shall be an "AFFECTED LENDER" and it shall on that day give notice (by telefacsimile or by telephone confirmed in writing) to Company and Administrative Agent of such determination (which notice Agent shall promptly transmit to each other Lender). Thereafter (a) the obligation of the Affected Lender to make Loans as, or to convert Loans to, Eurodollar Rate Loans shall be suspended until such notice shall be withdrawn by the Affected Lender, (b) to the extent such determination by the Affected Lender relates to a Eurodollar Rate Loan then being requested by Company pursuant to a Notice of Borrowing or a Notice of Conversion/Continuation, the Affected Lender shall make such Loan as (or convert such Loan to, as the case may be) a Base Rate Loan, (c) the Affected Lender's obligation to maintain its outstanding Eurodollar Rate Loans (the "AFFECTED LOANS") shall be terminated at the earlier to occur of the expiration of the Interest Period then in effect with respect to the Affected Loans or when required by law, and (d) the Affected Loans shall automatically convert into Base Rate Loans on the date of such termination. Notwithstanding the foregoing, to the extent a determination by an Affected Lender as described above relates to a Eurodollar Rate Loan then being requested by Company pursuant to a Notice of Borrowing or a Notice of Conversion/Continuation, Company shall have the option, subject to the provisions of subsection 2.6D, to rescind such Notice of Borrowing or Notice of Conversion/Continuation as to all Lenders by giving notice (by telefacsimile or by telephone confirmed in writing) to Administrative Agent of such rescission on the date on which the Affected Lender gives notice of its determination as described above (which notice of rescission Administrative Agent shall promptly transmit to each other Lender). Except as provided in the immediately preceding sentence, nothing in this subsection 2.6C shall affect the obligation of any Lender other than an Affected Lender to make or maintain Loans as, or to convert Loans to, Eurodollar Rate Loans in accordance with the terms of this Agreement.

D. COMPENSATION FOR BREAKAGE OR NON-COMMENCEMENT OF INTEREST PERIODS. Company shall compensate each Lender, upon written request by that Lender (which request shall set forth the basis for requesting such amounts), for all reasonable losses, expenses and

-47-

liabilities (including, without limitation, any interest paid by that Lender to lenders of funds borrowed by it to make or carry its Eurodollar Rate Loans and any loss, expense or liability sustained by that Lender in connection with the liquidation or re-employment of such funds) which that Lender may sustain: (i) if for any reason (other than a default by that Lender) a borrowing of any Eurodollar Rate Loan does not occur on a date specified therefor in a Notice of Borrowing or a telephonic request for borrowing, or a conversion to or continuation of any Eurodollar Rate Loan does not occur on a date specified therefor in a Notice of Conversion/Continuation or a telephonic request for conversion or continuation, (ii) if any prepayment or other principal payment or any conversion of any of its Eurodollar Rate Loans occurs on a date prior to the last day of an Interest Period applicable to that Loan, (iii) if any prepayment of any of its Eurodollar Rate Loans is not made on any date specified in a notice of prepayment given by Company, or (iv) as a consequence of any other default by Company in the repayment of its Eurodollar Rate Loans when required by the terms of this Agreement.

E. BOOKING OF EURODOLLAR RATE LOANS. Any Lender may make, carry or transfer Eurodollar Rate Loans at, to, or for the account of any of its branch offices or the office of an Affiliate of that Lender.

F. ASSUMPTIONS CONCERNING FUNDING OF EURODOLLAR RATE LOANS. Calculation of all amounts payable to a Lender under this subsection 2.6 and under subsection 2.7A shall be made as though that Lender had actually funded each of its relevant Eurodollar Rate Loans through the purchase of a Eurodollar deposit bearing interest at the rate obtained pursuant to clause (i) of the definition of Adjusted Eurodollar Rate in an amount equal to the amount of such Eurodollar Rate Loan and having a maturity comparable to the relevant Interest Period and through the transfer of such Eurodollar deposit from an offshore office of that Lender to a domestic office of that Lender in the United States of America; provided, however, that each Lender may fund each of its Eurodollar Rate Loans in any manner it sees fit and the foregoing assumptions shall be utilized only for the purposes of calculating amounts payable under this subsection 2.6 and under subsection 2.7A.

G. EURODOLLAR RATE LOANS AFTER DEFAULT. After the occurrence of and during the continuation of a Potential Event of Default or an Event of Default,
(i) Company may not elect to have a Loan be made or maintained as, or converted to, a Eurodollar Rate Loan after the expiration of any Interest Period then in effect for that Loan and (ii) subject to the provisions of subsection 2.6D, any Notice of Borrowing or Notice of Conversion/Continuation given by Company with respect to a requested borrowing or conversion/continuation that has not yet occurred shall be deemed to be rescinded by Company.

2.7 INCREASED COSTS; TAXES; CAPITAL ADEQUACY.

A. COMPENSATION FOR INCREASED COSTS AND TAXES. Subject to the provisions of subsection 2.7B, in the event that any Lender shall determine (which determination shall, absent manifest error, be final and conclusive and binding upon all parties hereto) that any law, treaty or governmental rule, regulation or order, or any change therein or in the interpretation,

-48-

administration or application thereof (including the introduction of any new law, treaty or governmental rule, regulation or order), or any determination of a court or governmental authority, in each case that becomes effective after the date hereof, or compliance by such Lender with any guideline, request or directive issued or made after the date hereof by any central bank or other governmental or quasi-governmental authority (whether or not having the force of law):

(i) subjects such Lender (or its applicable lending office) to any additional Tax (other than any Tax on the overall net income of such Lender) with respect to this Agreement or any of its obligations hereunder or any payments to such Lender (or its applicable lending office) of principal, interest, fees or any other amount payable hereunder;

(ii) imposes, modifies or holds applicable any reserve (including without limitation any marginal, emergency, supplemental, special or other reserve), special deposit, compulsory loan, FDIC insurance or similar requirement against assets held by, or deposits or other liabilities in or for the account of, or advances or loans by, or other credit extended by, or any other acquisition of funds by, any office of such Lender (other than any such reserve or other requirements with respect to Eurodollar Rate Loans that are reflected in the definition of Adjusted Eurodollar Rate); or

(iii) imposes any other condition (other than with respect to a Tax matter) on or affecting such Lender (or its applicable lending office) or its obligations hereunder or the interbank Eurodollar market;

and the result of any of the foregoing is to increase the cost to such Lender of agreeing to make, making or maintaining Loans hereunder or to reduce any amount received or receivable by such Lender (or its applicable lending office) with respect thereto; then, in any such case, Company shall promptly pay to such Lender, upon receipt of the statement referred to in the next sentence, such additional amount or amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender in its sole discretion shall determine) as may be necessary to compensate such Lender for any such increased cost or reduction in amounts received or receivable hereunder. Such Lender shall deliver to Company (with a copy to Administrative Agent) a written statement, setting forth in reasonable detail the basis for calculating the additional amounts owed to such Lender under this subsection 2.7A, which statement shall be conclusive and binding upon all parties hereto absent manifest error.

B. WITHHOLDING OF TAXES.

(i) Payments to Be Free and Clear. All sums payable by Company under this Agreement and the other Loan Documents shall be paid free and clear of and (except to the extent required by law) without any deduction or withholding on account of any Tax (other than a Tax on the overall net income of any Lender)

-49-

imposed, levied, collected, withheld or assessed by or within the United States of America or any political subdivision in or of the United States of America or any other jurisdiction from or to which a payment is made by or on behalf of Company or by any federation or organization of which the United States of America or any such jurisdiction is a member at the time of payment.

(ii) Grossing-up of Payments. If Company or any other Person is required by law to make any deduction or withholding on account of any such Tax from any sum paid or payable by Company to Administrative Agent or any Lender under any of the Loan Documents:

(a) Company shall notify Administrative Agent of any such requirement or any change in any such requirement as soon as Company becomes aware of it;

(b) Company shall pay any such Tax before the date on which penalties attach thereto, such payment to be made (if the liability to pay is imposed on Company) for its own account or (if that liability is imposed on Administrative Agent or such Lender, as the case may be) on behalf of and in the name of Administrative Agent or such Lender;

(c) the sum payable by Company in respect of which the relevant deduction, withholding or payment is required shall be increased to the extent necessary to ensure that, after the making of that deduction, withholding or payment, Administrative Agent or such Lender, as the case may be, receives on the due date a net sum equal to what it would have received had no such deduction, withholding or payment been required or made; and

(d) within 30 days after paying any sum from which it is required by law to make any deduction or withholding, and within 30 days after the due date of payment of any Tax which it is required by clause (b) above to pay, Company shall deliver to Administrative Agent evidence satisfactory to the other affected parties of such deduction, withholding or payment and of the remittance thereof to the relevant taxing or other authority;

provided that no such additional amount shall be required to be paid to any Lender under clause (c) above except to the extent that any change after the date hereof (in the case of each Lender listed on the signature pages hereof) or after the date of the Assignment Agreement pursuant to which such Lender became a Lender (in the case of each other Lender) in any such requirement for a deduction, withholding or payment as is mentioned therein shall result in an increase in the rate of such deduction, withholding or payment from that in effect at the date of this Agreement or at the date of such Assignment Agreement, as the case may be, in respect of payments to such Lender.

-50-

(iii) Evidence of Exemption from U.S. Withholding Tax.

(a) Each Lender that is organized under the laws of any jurisdiction other than the United States or any state or other political subdivision thereof (for purposes of this subsection 2.7B(iii), a "NON-US LENDER") shall deliver to Administrative Agent for transmission to Company, on or prior to the Fourth Restatement Date (in the case of each Lender listed on the signature pages hereof) or on the date of the Assignment Agreement pursuant to which it becomes a Lender (in the case of each other Lender), and at such other times as may be necessary in the determination of Company or Administrative Agent (each in the reasonable exercise of its discretion), (1) two original copies of Internal Revenue Service Form 1001 or 4224 (or any successor forms), properly completed and duly executed by such Lender, together with any other certificate or statement of exemption required under the Internal Revenue Code or the regulations issued thereunder to establish that such Lender is not subject to deduction or withholding of United States federal income tax with respect to any payments to such Lender of principal, interest, fees or other amounts payable under any of the Loan Documents or
(2) if such Lender is not a "bank" or other Person described in
Section 881(c)(3) of the Internal Revenue Code and cannot deliver either Internal Revenue Service Form 1001 or 4224 pursuant to clause (1) above, a Certificate re Non-Bank Status together with two original copies of Internal Revenue Service Form W-8 (or any successor form), properly completed and duly executed by such Lender, together with any other certificate or statement of exemption required under the Internal Revenue Code or the regulations issued thereunder to establish that such Lender is not subject to deduction or withholding of United States federal income tax with respect to any payments to such Lender of interest payable under any of the Loan Documents.

(b) Each Lender required to deliver any forms, certificates or other evidence with respect to United States federal income tax withholding matters pursuant to subsection 2.7B(iii)(a) hereby agrees, from time to time after the initial delivery by such Lender of such forms, certificates or other evidence, whenever a lapse in time or change in circumstances renders such forms, certificates or other evidence obsolete or inaccurate in any material respect, such Lender shall (1) deliver to Administrative Agent for transmission to Company two new original copies of Internal Revenue Service Form 1001 or 4224, or a Certificate re Non-Bank Status and two original copies of Internal Revenue Service Form W-8, as the case may be, properly completed and duly executed by such Lender, together with any other certificate or statement of exemption required in order to confirm or establish that such Lender is not subject to deduction or withholding of United States federal income tax with respect to payments to such Lender under the Loan Documents or (2) immediately notify Administrative Agent and Company of its inability to deliver any such forms, certificates or other evidence.

-51-

(c) Company shall not be required to pay any additional amount to any Non-US Lender under clause (c) of subsection 2.7B(ii) if such Lender shall have failed to satisfy the requirements of subsection 2.7B(iii)(a); provided that if such Lender shall have satisfied such requirements on the Fourth Restatement Date (in the case of each Lender listed on the signature pages hereof) or on the date of the Assignment Agreement pursuant to which it became a Lender (in the case of each other Lender), nothing in this subsection 2.7B(iii)(c) shall relieve Company of its obligation to pay any additional amounts pursuant to clause (c) of subsection 2.7B(ii) in the event that, as a result of any change in any applicable law, treaty or governmental rule, regulation or order, or any change in the interpretation, administration or application thereof, such Lender is no longer properly entitled to deliver forms, certificates or other evidence at a subsequent date establishing the fact that such Lender is not subject to withholding as described in subsection 2.7B(iii)(a).

C. CAPITAL ADEQUACY ADJUSTMENT. If any Lender shall have determined that the adoption, effectiveness, phase-in or applicability after the date hereof of any law, rule or regulation (or any provision thereof) regarding capital adequacy, or any change therein or in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its applicable lending office) with any guideline, request or directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of, or with reference to, such Lender's Loans or Commitments or other obligations hereunder to a level below that which such Lender or such controlling corporation could have achieved but for such adoption, effectiveness, phase-in, applicability, change or compliance (taking into consideration the policies of such Lender or such controlling corporation with regard to capital adequacy), then from time to time, within five Business Days after receipt by Company from such Lender of the statement referred to in the next sentence, Company shall pay to such Lender such additional amount or amounts as will compensate such Lender or such controlling corporation on an after-tax basis for such reduction. Such Lender shall deliver to Company (with a copy to Administrative Agent) a written statement, setting forth in reasonable detail the basis of the calculation of such additional amounts, which statement shall be conclusive and binding upon all parties hereto absent manifest error.

D. SUBSTITUTE LENDERS. In the event Company is required under the provisions of this subsection 2.7 to make payments in a material amount to any Lender or in the event any Lender fails to lend to Company in accordance with this Agreement, Company may, so long as no Event of Default or Potential Event of Default shall have occurred and be continuing, elect to terminate such Lender as a party to this Agreement; provided that, concurrently with

-52-

such termination, (i) Company shall pay that Lender all principal, interest and fees and other amounts (including without limitation, amounts, if any, owed under this subsection 2.7) owed to such Lender through such date of termination,
(ii) another financial institution satisfactory to Company and Administrative Agent (or if Administrative Agent is also the Lender to be terminated, the successor Administrative Agent) shall agree, as of such date, to become a Lender for all purposes under this Agreement (whether by assignment or amendment) and to assume all obligations of the Lender to be terminated as of such date, and
(iii) all documents and supporting materials necessary, in the judgment of Administrative Agent (or if Administrative Agent is also the Lender to be terminated, the successor Administrative Agent) to evidence the substitution of such Lender shall have been received and approved by Administrative Agent as of such date.

2.8 OBLIGATION OF LENDERS TO MITIGATE.

Each Lender agrees that, as promptly as practicable after the officer of such Lender responsible for administering the Loans of such Lender becomes aware of the occurrence of an event or the existence of a condition that would cause such Lender to become an Affected Lender or that would entitle such Lender to receive payments under subsection 2.7, it will, to the extent not inconsistent with the internal policies of such Lender and any applicable legal or regulatory restrictions, use reasonable efforts (i) to make, issue, fund or maintain the Commitments of such Lender or the affected Loans of such Lender through another lending office of such Lender, or (ii) take such other measures as such Lender may deem reasonable, if as a result thereof the circumstances which would cause such Lender to be an Affected Lender would cease to exist or the additional amounts which would otherwise be required to be paid to such Lender pursuant to subsection 2.7 would be materially reduced and if, as determined by such Lender in its sole discretion, the making, issuing, funding or maintaining of such Commitments or Loans through such other lending office or in accordance with such other measures, as the case may be, would not otherwise materially adversely affect such Commitments or Loans or the interests of such Lender; provided that such Lender will not be obligated to utilize such other lending office pursuant to this subsection 2.8 unless Company agrees to pay all incremental expenses incurred by such Lender as a result of utilizing such other lending office as described in clause (i) above. A certificate as to the amount of any such expenses payable by Company pursuant to this subsection 2.8 (setting forth in reasonable detail the basis for requesting such amount) submitted by such Lender to Company (with a copy to Administrative Agent) shall be conclusive absent manifest error.

2.9 RELEASE OF COLLATERAL.

Upon the prepayment of all Loans made with respect to a specific Financed Aircraft pursuant to subsection 2.4B(iv)(a) hereof, Administrative Agent, at the reasonable expense of Company, agrees to execute and deliver to Company such documents as shall be reasonably satisfactory to Company to evidence the release of the Liens granted pursuant to the Collateral Documents with respect to such Financed Aircraft and shall use its best efforts to return the originals of all Notes representing such Loans to Company, marked "Paid."

5.6 COMPLIANCE WITH LAWS, ETC.

Company will, and will cause its Subsidiaries to, comply with the requirements of all applicable laws, rules, regulations and orders of any governmental authority (including, without limitation, Environmental Laws), noncompliance with which could reasonably be expected to cause a Material Adverse Effect.

5.9 FURTHER ASSURANCES; NEW SUBSIDIARIES; HOLDING COMPANY.

A. At any time or from time to time upon the request of Administrative Agent, Company will, at its expense, promptly execute, acknowledge and deliver such further documents and do such other acts and things as Administrative Agent may reasonably request in order to effect fully the purposes of the Loan Documents and to provide for payment of the Obligations in accordance with the terms of this Agreement, the Notes and the other Loan Documents.

B. In furtherance and not in limitation of the foregoing, Company will cause any Subsidiary whose total assets exceed 15% of the consolidated total assets of Company, in each case determined in accordance with GAAP (other than a Special Purpose Subsidiary or Atlas

-75-

One), to take such actions as Administrative Agent may reasonably request from time to time to ensure that the Obligations are guarantied by any such Subsidiary. If, after the Fourth Restatement Date, Company or any of its Subsidiaries (other than a Special Purpose Subsidiary or Atlas One) acquires any asset, other than an aircraft financed with Loans hereunder or with Other Permitted Indebtedness, with a fair market value in excess of $5 million, or the value of spare parts of Company and its Subsidiaries not subject to Liens securing Designated Indebtedness exceeds $25 million in the aggregate, Company shall so notify Administrative Agent and take, or cause such Subsidiaries to take, such actions as Administrative Agent may reasonably request from time to time (including, without limitation, the execution and delivery of guaranties, security agreements, mortgages, deeds of trust, financing statements and other documents, the filing or recording of any of the foregoing, title insurance with respect to any of the foregoing that relates to an interest in real property, and the delivery of stock certificates and other collateral with respect to which perfection is obtained by possession) to ensure that the Obligations are secured by a first priority security interest in such asset or spare parts (other than capital stock of a Subsidiary), as the case may be; provided that, in the case of any engine otherwise subject to such security interest, such Lien may be released at the request of Company in connection with a refinancing thereof with Other Permitted Indebtedness. Notwithstanding the foregoing, so long as the AFL III Financing remains outstanding nothing herein shall cause or give rise to an obligation on the part of the Company or AFL III to require a guaranty or grant of security interest in the assets of AFL III. The Lenders acknowledge that the security interests and Liens created by the Collateral Documents do not extend to the assets of AFL III now existing or hereafter acquired.

C. In furtherance and not in limitation of the foregoing, if Company interposes a Holding Company, Company will cause the Holding Company to take such actions (including, without limitation, the execution and delivery of a guaranty, pledge agreement, financing statements and other documents, the filing or recording of any of the foregoing, and the delivery of stock certificates properly endorsed for transfer or accompanied by duly executed stock powers) as Administrative Agent and Lenders may reasonably request to ensure that the Obligations are guarantied by the Holding Company and that the Obligations are secured by a first priority security interest in all of the capital stock of Company. Company agrees that the Holding Company will not incur, directly or indirectly, any Indebtedness and will not engage in any business or activity or own any assets other than (1) holding the capital stock of Company or other Subsidiaries formed by the Holding Company, and performing its obligations incidental thereto, (2) employing certain management employees and pilots and performing its obligations incidental thereto, (3) paying general administrative costs and expenses in the ordinary course of business and (4) such other activities as may be consented to from time to time by Requisite Lenders.

5.10 APPRAISALS.

At the request of Administrative Agent or Requisite Lenders (but no more than once each calendar year), Company will obtain appraisals of each of the Financed Aircraft from two

-76-

Approved Appraisers, in form and substance satisfactory to Administrative Agent; provided that, upon the occurrence and during the continuance of an Event of Default, Company will obtain such additional appraisals with respect to the Financed Aircraft as Administrative Agent or Requisite Lenders may request.

5.11 MAINTENANCE CONTRACTS.

Company shall maintain contracts with respect to the maintenance of each Financed Aircraft sufficient to insure compliance with the Federal Aviation Act, in form and substance reasonably satisfactory to Administrative Agent.

5.12 EMPLOYEE BENEFIT PLANS.

Company will not establish or permit to be established any Employee Benefit Plans for Company or any of its employees and will not permit any ERISA Affiliate to establish any Employee Benefit Plan which, in either case, could result in a liability for Company, under ERISA, in excess of $10 million.

5.13 REGISTRATION OF FOREIGN LEASED AIRCRAFT WITH FAA.

Upon termination of an Approved Lease to which a Foreign Leased Aircraft is subject, Company shall cause such Foreign Leased Aircraft to be deregistered in such country and registered under the Federal Aviation Act and file for recordation with the FAA following such deregistration a First Aircraft Chattel Mortgage and Second Aircraft Chattel Mortgage with respect to such Foreign Leased Aircraft and shall cause FAA counsel to deliver an opinion in form and substance satisfactory to Administrative Agent.

5.14 CORPORATE SEPARATENESS.

Following the creation of a Holding Company, Company will take all such action as is necessary to keep its operations separate and apart from those of Holding Company or any of its Affiliates, including, without limitation, ensuring that all customary corporate formalities, including the maintenance of separate corporate records and documents and holding regular meetings are followed. Any financial statements distributed to any creditors of Company shall clearly establish the corporate separateness of Company from Holding Company and each Holding Company Subsidiary. Company shall not take any action or conduct its affairs in a manner that is likely to result in the corporate existence of Company on the one hand and of Holding Company or any Holding Company Subsidiary on the other hand being disregarded, or in the assets and liabilities of Holding Company or any Holding Company Subsidiary being substantively consolidated with those of Company in a bankruptcy, reorganization or other insolvency proceeding. Company shall maintain its principal executive office separate from Holding Company or any of its Affiliates.

7.11 FAILURE OF SECURITY.

Upon execution and delivery thereof, any Collateral Document shall, at any time, cease to be in full force and effect (other than by reason of a release of Collateral thereunder in accordance with the terms hereof or thereof, the satisfaction in full of the Obligations or any other termination of such Collateral Document in accordance with the terms hereof or thereof) or shall be declared null and void, or the validity or enforceability thereof shall be contested in writing by any Loan Party, or Administrative Agent shall not have or shall cease to have a valid security interest in any Collateral purported to be covered thereby, perfected and with the priority required by the relevant Collateral Document, for any reason other than the failure of Administrative Agent or any Lender to take any action within its control, subject only to Liens permitted under the applicable Collateral Documents; or

The provisions of this paragraph are intended merely to bind Lenders to a decision which may be made at the election of Requisite Lenders and are not intended to benefit Company and do not grant Company the right to require Lenders to rescind or annul any acceleration hereunder, even if the conditions set forth herein are met.

The provisions of this Section 8 are solely for the benefit of Administrative Agent and Lenders and Company shall have no rights as a third party beneficiary of any of the provisions thereof. In performing its functions and duties under this Agreement, Administrative Agent shall act solely as an agent of Lenders and does not assume and shall not be deemed to have assumed any obligation towards or relationship of agency or trust with or for Company or any of its Subsidiaries.

8.2 POWERS AND DUTIES; GENERAL IMMUNITY.

A. POWERS; DUTIES SPECIFIED. Each Lender irrevocably authorizes Administrative Agent to take such action on such Lender's behalf and to exercise such powers, rights and remedies hereunder and under the other Loan Documents as are specifically delegated or granted to Administrative Agent by the terms hereof and thereof, together with such powers, rights and remedies as are reasonably incidental thereto. Administrative Agent shall have only those duties and responsibilities that are expressly specified in this Agreement and the other Loan Documents. Administrative Agent may exercise such powers, rights and remedies and perform such duties by or through its agents or employees. Administrative Agent shall not have, by reason of this Agreement or any of the other Loan Documents, a fiduciary relationship in respect of any Lender; and nothing in this Agreement or any of the other Loan Documents, expressed or implied, is intended to or shall be so construed as to impose upon Administrative Agent any obligations in respect of this Agreement or any of the other Loan Documents except as expressly set forth herein or therein.

B. NO RESPONSIBILITY FOR CERTAIN MATTERS. Administrative Agent shall not be responsible to any Lender for the execution, effectiveness, genuineness, validity, enforceability, collectibility or sufficiency of this Agreement or any other Loan Document or for any representations, warranties, recitals or statements made herein or therein or made in any written or oral statements or in any financial or other statements, instruments, reports or certificates or any other documents furnished or made by Administrative Agent to Lenders or by or on behalf of Company to Administrative Agent or any Lender in connection with the Loan Documents and the transactions contemplated thereby or for the financial condition or business affairs of Company or any other Person liable for the payment of any Obligations, nor shall Administrative Agent be required to ascertain or inquire as to the performance or

-95-

observance of any of the terms, conditions, provisions, covenants or agreements contained in any of the Loan Documents or as to the use of the proceeds of the Loans or as to the existence or possible existence of any Event of Default or Potential Event of Default.

C. EXCULPATORY PROVISIONS. Neither of Administrative Agent nor any of its officers, directors, partners, employees or agents shall be liable to Lenders for any action taken or omitted by Administrative Agent under or in connection with any of the Loan Documents except to the extent caused by Administrative Agent's gross negligence or willful misconduct. If Administrative Agent shall request instructions from Lenders with respect to any act or action (including the failure to take an action) in connection with this Agreement or any of the other Loan Documents, Administrative Agent shall be entitled to refrain from such act or taking such action unless and until Administrative Agent shall have received instructions from Requisite Lenders. Without prejudice to the generality of the foregoing, (i) Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any communication, instrument or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and shall be entitled to rely and shall be protected in relying on opinions and judgments of attorneys (who may be attorneys for Company and its Subsidiaries), accountants, experts and other professional advisors selected by it; and (ii) no Lender shall have any right of action whatsoever against Administrative Agent as a result of Administrative Agent acting or (where so instructed) refraining from acting under this Agreement or any of the other Loan Documents in accordance with the instructions of Requisite Lenders.

-96-

8.3 REPRESENTATIONS AND WARRANTIES; NO RESPONSIBILITY FOR APPRAISAL OF CREDITWORTHINESS.

Each Lender represents and warrants that it has made its own independent investigation of the financial condition and affairs of Company and its Subsidiaries in connection with the making of the Loans hereunder and that it has made and shall continue to make its own appraisal of the creditworthiness of Company and its Subsidiaries. Administrative Agent shall have no duty or responsibility, either initially or on a continuing basis, to make any such investigation or any such appraisal on behalf of Lenders or to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before the making of the Loans or at any time or times thereafter, and Administrative Agent shall not have responsibility with respect to the accuracy of or the completeness of any information provided to Lenders.

8.4 RIGHT TO INDEMNITY.

Each Lender, in proportion to its Pro Rata Share, severally agrees to indemnify Administrative Agent (and its respective affiliates and partners), to the extent that Administrative Agent shall not have been reimbursed by Company, for and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses (including, without limitation, counsel fees and disbursements) or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against Administrative Agent in exercising its powers, rights and remedies or performing its duties hereunder or under the other Loan Documents or otherwise in its capacity as Administrative Agent, in any way relating to or arising out of this Agreement or the other Loan Documents; provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Administrative Agent's gross negligence or willful misconduct.

8.5 COLLATERAL DOCUMENTS.

Without limiting the generality of subsection 8.1, each Lender hereby further authorizes Administrative Agent to enter into the Collateral Documents as secured party on behalf of and for the benefit of such Lender and agrees to be bound by the terms of each of the Collateral Documents; provided that, except as otherwise provided below, Administrative Agent shall not enter into or consent to any amendment, modification, termination or waiver of any provision contained in any Collateral Document without prior written consent of Requisite Lenders. Anything contained in any of the Loan Documents to the contrary notwithstanding, each Lender agrees that no Lender shall have any right individually to realize upon any of the collateral under any Collateral Document, it being understood and agreed that all powers, rights and remedies under the Collateral Documents may be exercised solely by Administrative Agent for the benefit of Lenders in accordance with the terms thereof. Each Lender hereby authorizes Administrative Agent (i) to release or subordinate Collateral as permitted or required under this Agreement or the Collateral Documents, and agrees that a

-97-

certificate executed by Administrative Agent evidencing such release of Collateral shall be conclusive evidence of such release as to any third party and (ii) to enter into any amendments of the Collateral Documents to cure any ambiguity, defect or inconsistency or to amend provisions relating to ministerial or administrative matters which do not materially adversely affect the rights of the Lenders thereunder.

8.6 SUCCESSOR ADMINISTRATIVE AGENT.

Administrative Agent may resign at any time by giving 30 days' prior written notice thereof to Lenders and Company. Upon any such notice of resignation, Requisite Lenders shall have the right, upon consultation with Company, to appoint a successor Administrative Agent. Upon the acceptance of any appointment hereunder by a successor Administrative Agent, that successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent and the retiring or removed Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent's resignation hereunder as Administrative Agent, the provisions of this Section 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement.

SECTION 9. MISCELLANEOUS

9.1 ASSIGNMENTS AND PARTICIPATIONS IN LOANS.

A. GENERAL. Each Lender shall have the right at any time to (i) sell, assign or transfer to any Eligible Assignee, or (ii) sell participations to any Person in, all or any part of its Commitments or any Loan or Loans made by it or any other interest herein or in any other Obligations owed to it; provided that no such sale, assignment, transfer or participation shall, without the consent of Company, require Company to file a registration statement with the Securities and Exchange Commission or apply to qualify such sale, assignment, transfer or participation under the securities laws of any state; provided, further that no such sale, assignment or transfer described in clause (i) above shall be effective unless and until (a) an Assignment Agreement effecting such sale, assignment or transfer shall have been accepted by Administrative Agent and recorded in the Register as provided in subsection 9.1B(ii) or (b) the sale, assignment or transfer is made in accordance with subsection 9.21. Except as otherwise provided in this subsection 9.1, no Lender shall, as between Company and such Lender, be relieved of any of its obligations hereunder as a result of any sale, assignment or transfer of, or any granting of participations in, all or any part of its Commitments or the Loans, or the other Obligations owed to such Lender.

-98-

B. ASSIGNMENTS.

(i) Amounts and Terms of Assignments. Each Commitment, Loan or other Obligation may (a) be assigned in any amount to another Lender, or to an Affiliate of the assigning Lender or another Lender, with the giving of notice to Company and Administrative Agent or (b) be assigned in an aggregate amount of not less than $5,000,000 (or such lesser amount as shall constitute the aggregate amount of the Commitments, Loans, and other Obligations of the assigning Lender) to any other Eligible Assignee with the giving of notice to Company and with the consent of Administrative Agent and Company (which consent shall not be unreasonably withheld). Any assignment of Loans hereunder shall effect a pro rata assignment of the Notes with respect to each Financed Aircraft. To the extent of any such assignment in accordance with either clause (a) or (b) above, the assigning Lender shall be relieved of its obligations with respect to its Commitments, Loans, or other Obligations or the portion thereof so assigned. The parties to each such assignment shall execute and deliver to Administrative Agent, for its acceptance and recording in the Register, an Assignment Agreement, together with a processing and recordation fee of $3,000 and such forms, certificates or other evidence, if any, with respect to United States federal income tax withholding matters as the assignee under such Assignment Agreement may be required to deliver to Administrative Agent pursuant to subsection 2.7B(iii)(a); provided, however that such processing fee shall not be required where the assignee is an existing Lender. Upon such execution, delivery and acceptance, from and after the effective date specified in such Assignment Agreement, (y) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment Agreement, shall have the rights and obligations of a Lender hereunder and (z) the assigning Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment Agreement, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment Agreement covering all or the remaining portion of an assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto). The Commitments hereunder shall be modified to reflect the Commitment of such assignee and any remaining Commitment of such assigning Lender and, if any such assignment occurs after the issuance of the Notes hereunder, the assigning Lender shall, upon the effectiveness of such assignment or as promptly thereafter as practicable, surrender its applicable Notes to Administrative Agent for cancellation, and thereupon new Notes shall be issued to the assignee substantially in the form of Exhibit IIIA annexed hereto or Exhibit IIIB, as the case may be, with appropriate insertions, to reflect the new Commitments and/or outstanding Loans, as the case may be, of the assignee and/or the assigning Lender.

(ii) Acceptance by Administrative Agent; Recordation in Register. Upon its receipt of an Assignment Agreement executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with the processing and recordation fee referred to in subsection 9.1B(i) and any forms, certificates or other evidence with respect to United States federal income tax withholding matters that

-99-

such assignee may be required to deliver to Administrative Agent pursuant to subsection 2.7B(iii)(a), Administrative Agent shall, if such Assignment Agreement has been completed and is in substantially the form of Exhibit VII hereto and if Administrative Agent has consented to the assignment evidenced thereby to the extent such consent is required pursuant to subsection 9.1B(i)), (a) accept such Assignment Agreement by executing a counterpart thereof as provided therein (which acceptance shall evidence any required consent of Administrative Agent to such assignment), (b) record the information contained therein in the Register and (c) give prompt notice thereof to Company. Administrative Agent shall maintain a copy of each Assignment Agreement delivered to and accepted by it as provided in this subsection 9.1B(ii).

C. PARTICIPATIONS. The holder of any participation, other than an Affiliate of the Lender granting such participation, shall not be entitled to require such Lender to take or omit to take any action hereunder except action directly affecting (i) the extension of the scheduled final maturity date of any Loan allocated to such participation, (ii) a reduction of the principal amount of or the rate of interest payable on any Loan allocated to such participation or (iii) a release of Collateral, and all amounts payable by Company hereunder (including without limitation amounts payable to such Lender pursuant to subsections 2.6D and 2.7) shall be determined as if such Lender had not sold such participation. Company and each Lender hereby acknowledge and agree that, solely for purposes of subsection 9.5, (a) any participation will give rise to a direct obligation of Company to the participant and (b) the participant shall be considered to be a "Lender".

D. ASSIGNMENTS TO FEDERAL RESERVE BANKS. In addition to the assignments and participations permitted under the foregoing provisions of this subsection 9.1, any Lender may assign and pledge all or any portion of its Loans, the other Obligations owed to such Lender, and its Notes to any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any operating circular issued by such Federal Reserve Bank; provided that (i) no Lender shall, as between Company and such Lender, be relieved of any of its obligations hereunder as a result of any such assignment and pledge and (ii) in no event shall such Federal Reserve Bank be considered to be a "Lender" or be entitled to require the assigning Lender to take or omit to take any action hereunder.

E. INFORMATION. Each Lender may furnish any information concerning Company and its Subsidiaries in the possession of that Lender from time to time to assignees and participants (including prospective assignees and participants), subject to subsection 9.19.

9.2 EXPENSES.

Whether or not the transactions contemplated hereby shall be consummated, Company agrees to pay promptly (i) all the actual and reasonable costs and expenses of preparation of the Loan Documents; (ii) all the costs of furnishing all opinions by counsel for Company (including without limitation any opinions requested by Lenders as to any legal matters arising hereunder) and of Company's performance of and compliance with all agreements and

-100-

conditions on its part to be performed or complied with under this Agreement and the other Loan Documents including, without limitation, with respect to confirming compliance with environmental and insurance requirements; (iii) the reasonable fees, expenses and disbursements of counsel to Administrative Agent in connection with the negotiation, preparation, execution and administration of the Loan Documents and the Loans and any consents, amendments, waivers or other modifications hereto or thereto and any other documents or matters requested by Company; (iv) all the costs and expenses of creating and perfecting the Liens in favor of Administrative Agent for the benefit of Lenders pursuant to the Loan Documents, including filing and recording fees and expenses, title insurance, fees and expenses of counsel for providing such opinions as Lenders may reasonably request and fees and expenses of legal counsel to Administrative Agent (including local counsel); (v) all other actual and reasonable costs and expenses incurred by Administrative Agent in connection with the syndication of the Commitments and the negotiation, preparation and execution of the Loan Documents and the transactions contemplated hereby and thereby; provided that such costs and expenses of syndication shall not exceed $10,000; and (vi) after the occurrence of an Event of Default, all costs and expenses, including reasonable attorneys' fees (including allocated costs of internal counsel) and costs of settlement, incurred by Administrative Agent and Lenders in enforcing any Obligations of or in collecting any payments due from Company hereunder or under the other Loan Documents by reason of such Event of Default or in connection with any refinancing or restructuring of the credit arrangements provided under this Agreement in the nature of a "work-out" or pursuant to any insolvency or bankruptcy proceedings.

9.3 INDEMNITY.

In addition to the payment of expenses pursuant to subsection 9.2, whether or not the transactions contemplated hereby shall be consummated, Company agrees to defend, indemnify, pay and hold harmless Administrative Agent and Lenders, and the officers, directors, partners, employees, agents and affiliates of Administrative Agent and Lenders (collectively called the "INDEMNITIES") from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and disbursements of any kind or nature whatsoever (including without limitation the reasonable fees and disbursements of counsel for such Indemnities in connection with any investigative, administrative or judicial proceeding commenced or threatened by any Person, whether or not any such Indemnitee shall be designated as a party or a potential party thereto), whether direct, indirect or consequential and whether based on any federal, state or foreign laws, statutes, rules or regulations (including without limitation securities and commercial laws, statutes, rules or regulations and Environmental Laws), on common law or equitable cause or on contract or otherwise, that may be imposed on, incurred by, or asserted against any such Indemnitee, in any manner relating to or arising out of this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby (including without limitation Lenders' agreement to make the Loans hereunder or the use or intended use of the proceeds of any of the Loans) or the statements contained in the commitment letter delivered by any Lender to Company with respect thereto (collectively called the "INDEMNIFIED LIABILITIES");

-101-

provided that Company shall not have any obligation to any Indemnitee hereunder with respect to any Indemnified Liabilities to the extent such Indemnified Liabilities arise solely from the gross negligence or willful misconduct of that Indemnitee as determined by a final judgment of a court of competent jurisdiction. To the extent that the undertaking to defend, indemnify, pay and hold harmless set forth in the preceding sentence may be unenforceable because it is violative of any law or public policy, Company shall contribute the maximum portion that it is permitted to pay and satisfy under applicable law to the payment and satisfaction of all Indemnified Liabilities incurred by the Indemnities or any of them.

9.4 SET-OFF.

In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence of any Event of Default each Lender is hereby authorized by Company at any time or from time to time, without notice to Company or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, Indebtedness evidenced by certificates of deposit, whether matured or unmatured, but not including trust accounts) and any other Indebtedness at any time held or owing by that Lender to or for the credit or the account of Company against and on account of the obligations and liabilities of Company to that Lender under this Agreement, the Notes, and the other Loan Documents, including, but not limited to, all claims of any nature or description arising out of or connected with this Agreement, the Notes, or any other Loan Document, irrespective of whether or not (i) that Lender shall have made any demand hereunder or (ii) the principal of or the interest on the Loans or any other amounts due hereunder shall have become due and payable pursuant to Section 7 and although said obligations and liabilities, or any of them, may be contingent or unmatured.

9.5 RATABLE SHARING.

Lenders hereby agree among themselves that if any of them shall, whether by voluntary payment, by realization upon security, through the exercise of any right of set-off or banker's lien, by counterclaim or cross action or by the enforcement of any right under the Loan Documents or otherwise, or as adequate protection of a deposit treated as cash collateral under the Bankruptcy Code, receive payment or reduction of a proportion of the aggregate amount of principal, interest, fees and other amounts then due and owing to that Lender hereunder or under the other Loan Documents (collectively, the "AGGREGATE AMOUNTS DUE" to such Lender) which is greater than the proportion received by any other Lender in respect of the Aggregate Amounts Due to such other Lender, then the Lender receiving such proportionately greater payment shall (i) notify Administrative Agent and each other Lender of the receipt of such payment and
(ii) apply a portion of such payment to purchase participations (which it shall be deemed to have purchased from each seller of a participation simultaneously upon the receipt by such seller of its portion of such payment) in the Aggregate Amounts Due to the other Lenders so that all such recoveries of Aggregate Amounts Due shall be shared by all Lenders in proportion to the Aggregate Amounts Due to

-102-

them; provided that if all or part of such proportionately greater payment received by such purchasing Lender is thereafter recovered from such Lender upon the bankruptcy or reorganization of Company or otherwise, those purchases shall be rescinded and the purchase prices paid for such participations shall be returned to such purchasing Lender ratably to the extent of such recovery, but without interest. Company expressly consents to the foregoing arrangement and agrees that any holder of a participation so purchased may exercise any and all rights of banker's lien, set-off or counterclaim with respect to any and all monies owing by Company to that holder with respect thereto as fully as if that holder were owed the amount of the participation held by that holder.

9.6 AMENDMENTS AND WAIVERS.

A. No amendment, modification, termination or waiver of any provision of this Agreement or of the Notes, or consent to any departure by Company therefrom, shall in any event be effective without the written concurrence of Requisite Lenders; provided that any such amendment, modification, termination, waiver or consent which: increases the amount of any of the Commitments or reduces the principal amount of any of the Loans; changes any Lender's Pro Rata Share; changes in any manner the definition of "Requisite Lenders"; changes in any manner any provision of this Agreement which, by its terms, expressly requires the approval or concurrence of all Lenders; postpones the Final Scheduled Maturity Date (but not the date of any scheduled installment of principal) of any of the Loans; postpones the date on which any interest or any fees are payable; decreases the interest rate borne by any of the Loans (other than any waiver of any increase in the interest rate applicable to any of the Loans pursuant to subsection 2.2E) or the amount of any fees payable hereunder; increases the maximum duration of Interest Periods permitted hereunder; releases all or substantially all of the Collateral; or changes in any manner the provisions contained in subsection 7.1 or this subsection 9.6 shall be effective only if evidenced by a writing signed by or on behalf of all Lenders to whom are owed Obligations being directly affected by such amendment, modification, termination, waiver or consent. In addition, (i) any amendment, modification, termination or waiver of any of the provisions contained in Section 3 shall be effective only if evidenced by a writing signed by or on behalf of Administrative Agent and Requisite Lenders, (ii) no amendment, modification, termination or waiver of any provision of any Note shall be effective without the written concurrence of the Lender which is the holder of that Note, (iii) no increase in the Commitments of any Lender over the amount thereof then in effect shall be effective without the written concurrence of that Lender, it being understood and agreed that in no event shall waivers or modifications of conditions precedent, covenants, Events of Default, Potential Events of Default or of a mandatory prepayment or a reduction of any or all of the Commitments be deemed to constitute an increase of the Commitment of any Lender and that an increase in the available portion of any Commitment of any Lender shall not be deemed to constitute an increase in the Commitment of such Lender, and (iv) no amendment, modification, termination or waiver of any provision of Section 7 or of any other provision of this Agreement which, by its terms, expressly requires the approval or concurrence of Administrative Agent shall be effective without the written concurrence of Administrative Agent. Administrative Agent may, but shall have no obligation to, with the

-103-

concurrence of any Lender, execute amendments, modifications, waivers or consents on behalf of that Lender. Any waiver or consent shall be effective only in the specific instance and for the specific purpose for which it was given. No notice to or demand on Company in any case shall entitle Company to any other or further notice or demand in similar or other circumstances. Any amendment, modification, termination, waiver or consent effected in accordance with this subsection 9.6 shall be binding upon each Lender at the time outstanding, each future Lender and, if signed by Company, on Company. Notwithstanding anything in this subsection 9.6A to the contrary, the Notes and Aircraft Chattel Mortgages may be amended in the manner and for the purposes set forth in subsection 9.21 without the consents required by this subsection 9.6A.

B. If, in connection with any proposed change, waiver, discharge or termination to any of the provision of this Agreement as contemplated by the proviso in the first sentence of this subsection 9.6, the consent of Requisite Lenders is obtained but consent of one or more of such other Lenders whose consent is required is not obtained, then Company may, so long as all non-consenting Lenders are so treated, elect to terminate such Lender as a party to this Agreement; provided that, concurrently with such termination, (i) Company shall pay that Lender all principal, interest and fees and other amounts owed to such Lender through such date of termination, (ii) another financial institution satisfactory to Company and Administrative Agent (or if Administrative Agent is also the Lender to be terminated, the successor Administrative Agent) shall agree, as of such date, to become a Lender for all purposes under this Agreement (whether by assignment or amendment) and to assume all obligations of the Lender to be terminated as of such date, and (iii) all documents and supporting materials necessary, in the judgment of Administrative Agent (or if Administrative Agent is also the Lender to be terminated, the successor Administrative Agent) to evidence the substitution of such Lender shall have been received and approved by Administrative Agent as of such date.

9.7 INDEPENDENCE OF COVENANTS.

All covenants under this Agreement shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or would otherwise be within the limitations of, another covenant shall not avoid the occurrence of an Event of Default or Potential Event of Default if such action is taken or condition exists.

9.8 NOTICES.

Unless otherwise specifically provided herein, any notice or other communication herein required or permitted to be given shall be in writing and may be personally served, telexed or sent by telefacsimile or United States mail or courier service and shall be deemed to have been given when delivered in person or by courier service, upon receipt of telefacsimile or telex, or three Business Days after depositing it in the United States mail with postage prepaid and properly addressed; provided that notices to Administrative Agent shall not be

Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of any Lender to bring proceedings against Company in the courts of any other jurisdiction.

9.18 WAIVER OF JURY TRIAL.

EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS LOAN TRANSACTION OR THE LENDER/BORROWER RELATIONSHIP THAT IS BEING ESTABLISHED.

-108-

Mortgage and Second Aircraft Chattel Mortgage, in each case, as requested by Company; provided that the terms of such amended Notes and Aircraft Chattel Mortgages do not violate any term of this Agreement and provided, further, that such amendments shall be effective only upon and simultaneous with (i) the assignment of such Notes and Aircraft Chattel Mortgages to such Person, (ii) indefeasible payment in full to Lenders of an amount equal to all amounts owing under such Notes and (iii) releases from any liability relating to such Notes and Aircraft Chattel Mortgages of Administrative Agent and Lenders in form and substance satisfactory to Administrative Agent.

9.22 REPLACEMENT ENGINES.

A. ENGINES. So long as no Event of Default or Potential Event of Default has occurred and is continuing, Company may, upon not less than five (5) Business Days prior written notice to Administrative Agent, replace any Engine which is the subject of an Aircraft Chattel Mortgage with another engine (the "Replacement Engine") meeting the requirements of the applicable Aircraft Chattel Mortgage.

(3) Except as may otherwise be required by law or by the provisions of such resolution or resolutions as may be adopted by the Board of Directors pursuant to section (b) of this Article FOURTH, each holder of Common Stock shall have one vote in respect of each share of Common Stock held on all matters voted upon by the stockholders.

(d) No holder of any of the shares of any class or series of stock or of options, warrants or other rights to purchase shares of any class or series of stock or of other securities of the Corporation shall have any preemptive right to purchase or subscribe for any unissued stock of any class or series or any additional shares of any class or series to be issued by reason of any increase of the authorized capital stock of the Corporation of any class or series, or bonds, certificates of indebtedness, debentures or other securities convertible into or exchangeable for stock of the Corporation of any class or series, or carrying any right to purchase stock of any class or series, but any such unissued stock, additional authorized issue of shares of any class or series of stock or securities convertible into or exchangeable for stock, or carrying any right to purchase stock, may be issued and disposed of pursuant to resolution of the Board of Directors to such persons, firms, corporations or associations, whether such holders or others, and upon such terms as may be deemed advisable by the Board of Directors in the exercise of its sole discretion.

(f) Subject to the provisions of section (e), shares of any series of Preferred Stock may be issued from time to time as the Board of Directors of the Corporation shall determine and on such terms and for such consideration as shall be fixed by the Board of Directors.

(g) Shares of Common Stock may be issued from time to time as the Board of Directors of the Corporation shall determine and on such terms and for such consideration as shall be fixed by the Board of Directors.

(h) The authorized amount of shares of Common Stock and of Preferred Stock may, without a class or series vote, be increased or decreased from time to time by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote thereon.

FIFTH: - (a) The business and affairs of the Corporation shall be conducted and managed by a Board of Directors. The number of directors constituting the entire Board shall be not less than five nor more than twenty-five as fixed from time to time by vote of a majority of the whole Board, provided, however, that the number of directors shall not be reduced so as to shorten the term of any director at the time in office, and provided further, that the number of directors constituting the whole Board shall be twenty-four until otherwise fixed by a majority of the whole Board.

(b) The Board of Directors shall be divided into three classes, as nearly equal in number as the then total number of directors constituting the whole Board permits, with the term of office of one class expiring each year.

Any vacancies in the Board of Directors for any reason, and any newly created directorships resulting from any increase in the directors, may be filled by the Board of Directors, acting by a majority of the directors then in office, although less than a quorum, and any directors so chosen shall hold office until the next annual election of directors. At such election, the stockholders shall elect a successor to such director to hold office until the next election of the class for which such director shall have been chosen and until his successor shall be elected and qualified. No decrease in the number of directors shall shorten the term of any incumbent director.

7

(c) Notwithstanding any other provisions of this Charter or Act of Incorporation or the By-Laws of the Corporation (and notwithstanding the fact that some lesser percentage may be specified by law, this Charter or Act of Incorporation or the By-Laws of the Corporation), any director or the entire Board of Directors of the Corporation may be removed at any time without cause, but only by the affirmative vote of the holders of two-thirds or more of the outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors (considered for this purpose as one class) cast at a meeting of the stockholders called for that purpose.

(d) Nominations for the election of directors may be made by the Board of Directors or by any stockholder entitled to vote for the election of directors. Such nominations shall be made by notice in writing, delivered or mailed by first class United States mail, postage prepaid, to the Secretary of the Corporation not less than 14 days nor more than 50 days prior to any meeting of the stockholders called for the election of directors; provided, however, that if less than 21 days' notice of the meeting is given to stockholders, such written notice shall be delivered or mailed, as prescribed, to the Secretary of the Corporation not later than the close of the seventh day following the day on which notice of the meeting was mailed to stockholders. Notice of nominations which are proposed by the Board of Directors shall be given by the Chairman on behalf of the Board.

(f) The Chairman of the meeting may, if the facts warrant, determine and declare to the meeting that a nomination was not made in accordance with the foregoing procedure, and if he should so determine, he shall so declare to the meeting and the defective nomination shall be disregarded.

-2-

of Transmittal (this "Letter"), which together constitute the offer (the "Exchange Offer") to exchange an aggregate principal amount of up to $217,317,000 of Pass Through Certificates, Series 2000-1 (the "New Certificates") for an equal principal amount of the outstanding Pass Through Certificates, Series 2000-1 (the "Old Certificates").

For each Old Certificate accepted for exchange, the holder of such Old Certificate will receive a New Certificate having a principal amount at maturity equal to that of the surrendered Old Certificate. The New Certificates will accrue interest at the applicable per annum rate for such Trust as set forth on the cover page of the Prospectus, from the last date on which interest was paid on the Old Certificates surrendered in exchange therefor. Interest on the New Certificates is payable on January 2 and July 2 of each year commencing upon the consummation of this Exchange Offer, subject to the terms of the Intercreditor Agreement (as defined in the Prospectus). In the event that neither the consummation of the Exchange Offer nor the declaration by the Commission of the Shelf Registration Statement to be effective (each a "Registration Event") occurs on or prior to the 210th calendar day after the Issue Date, the interest rate per annum borne by the Equipment Notes and passed through to holders of Old Certificates shall be increased by 0.50% from and including August 25, 2000, but excluding the date on which a Registration Event occurs. In the event that the Shelf Registration Statement ceases to be effective at any time, during the period the Company is required to keep such Shelf Registration Statement effective, for more than 60 days, whether or not consecutive, during any 12-month period, the interest rate per annum borne by the Equipment Notes shall be increased by 0.50% from the 61st day of the applicable 12-month period such Shelf Registration Statement ceases to be effective until such time as the Shelf Registration Statement again becomes effective. The Company reserves the right, at any time or from time to time, to extend the Exchange Offer at its discretion, in which event the term "Expiration Date" shall mean the latest time and date to which the Exchange Offer is extended. The Company shall notify the holders of the Old Certificates of any extension by means of a press release or other public announcement prior to 9:00
A.M., New York City time, on the next business day after the previously scheduled Expiration Date.

This Letter is to be completed by a holder of Old Certificates either if Old Certificates are to be forwarded herewith or if a tender of Old Certificates, if available, is to be made by book-entry transfer to the account maintained by the Exchange Agent at The Depository Trust Company (the "Book-Entry Transfer Facility") pursuant to the procedure set forth in "The Exchange Offer" section of the Prospectus. Holders of Old Certificates whose certificates are not immediately available, or who are unable to deliver their certificates or confirmation of the book-entry tender of their Old Certificates into the Exchange Agent's account at the Book-Entry Transfer Facility (a "Book-Entry Confirmation") and all other documents required by this Letter to the Exchange Agent on or prior to the Expiration Date, must tender their Old Certificates according to the guaranteed delivery procedures set forth in "The Exchange Offer - Guaranteed Delivery Procedures" section of the Prospectus.

PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

Upon the terms and subject to the conditions of the Exchange Offer, the undersigned hereby tenders to the Company the aggregate principal amount of Old Certificates indicated above. Subject to, and effective upon, the acceptance for exchange of the Old Certificates tendered hereby, the undersigned hereby sells, assigns and transfers to, or upon the order of, the Company all right, title and interest in and to such Old Certificates as are being tendered hereby.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Old Certificates tendered hereby and that the Company will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim when the same are accepted by the Company. The undersigned hereby further represents that any New Certificates acquired in exchange for Old Certificates tendered hereby will have been acquired in the ordinary course of business of the person receiving such New Certificates, whether or not such person is the undersigned, that neither the holder of such Old Certificates nor any such other person is engaged in, or intends to engage in a distribution of such New Certificates, or has an arrangement or understanding with any person to participate in the distribution of such New Certificates, and that neither the holder of such Old Certificates nor any such other person is an "affiliate," as defined in Rule 405 under the Securities Act of 1933, as amended (the "Securities Act"), of the Company.

The undersigned also acknowledges that this Exchange Offer is being made based upon the Company's understanding of an interpretation by the Staff of the Securities and Exchange Commission (the "Commission") as set forth in no-action letters issued to third parties, including Exxon Capital Holdings Corporation, SEC No-Action Letter (available May 13, 1988) (the "Exxon Capital Letter"), Morgan Stanley & Co. Incorporated, SEC No-Action Letter (available June 5, 1991) (the "Morgan Stanley Letter") and Shearman & Sterling, SEC No-Action Letter (available July 2, 1993) (the "Shearman & Sterling Letter"), that the New Certificates issued in exchange for the Old Certificates pursuant to the Exchange Offer may be offered for resale,


-7-

resold and otherwise transferred by holders thereof (other than a broker-dealer who acquires such New Certificates directly from the Company for resale pursuant to Rule 144A under the Securities Act or any other available exemption under the Securities Act or any such holder that is an "affiliate" of the Company within the meaning of Rule 405 under the Securities Act), without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such New Certificates are acquired in the ordinary course of such holders' business and such holders are not engaged in, and do not intend to engage in, a distribution of such New Certificates and have no arrangement with any person to participate in the distribution of such New Certificates. If a holder of Old Certificates is engaged in or intends to engage in a distribution of the New Certificates or has any arrangement or understanding with respect to the distribution of the New Certificates to be acquired pursuant to the Exchange Offer, such holder could not rely on the applicable interpretations of the Staff of the Commission and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any secondary resale transaction. If the undersigned is a broker-dealer that will receive New Certificates for its own account in exchange for the Old Certificates, it represents that the Old Certificates to be exchanged for the New Certificates were acquired by it as a result of market-making activities or other trading activities and acknowledges that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Certificates; however, by so acknowledging and by delivering a prospectus, the undersigned will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

The undersigned will, upon request, execute and deliver any additional documents deemed by the Company to be necessary or desirable to complete the sale, assignment and transfer of the Old Certificates tendered hereby. All authority conferred or agreed to be conferred in this Letter and every obligation of the undersigned hereunder shall be binding upon the successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of the undersigned and shall not be affected by, and shall survive, the death or incapacity of the undersigned. This tender may be withdrawn only in accordance with the procedures set forth in "The Exchange Offer -- Withdrawal of Tenders" section of the Prospectus.

INSTRUCTIONS

Forming Part of the Terms and Conditions of the Offer to Exchange Atlas Air, Inc. Pass Through Certificates, Series 2000-1 which have been registered under the Securities Act of 1933, as amended, for any and all Outstanding Atlas Air, Inc. Pass Through Certificates, Series 2000-1.

1. Delivery of this Letter and Old Certificates; Guaranteed Delivery Procedures.

This Letter is to be completed by holders of Old Certificates either if certificates are to be forwarded herewith or if tenders are to be made pursuant to the procedures for delivery by book-entry transfer set forth in "The Exchange Offer -- Book-Entry Transfer" section of the Prospectus. Certificates for all physically tendered Old Certificates, or Book-Entry Confirmation, as the case may be, as well as a properly completed and duly executed Letter of Transmittal (or facsimile thereof) and any other documents required by this Letter, must be received by the Exchange Agent at the address set forth herein on or prior to the Expiration Date, or the tendering holder must comply with the guaranteed delivery procedures set forth below. Old Certificates tendered hereby must be in denominations of principal amount at maturity of $1,000 and any integral multiple thereof.

Holders of Old Certificates whose certificates for Old Certificates are not immediately available or who cannot deliver their certificates and all other required documents to the Exchange Agent on or prior to the Expiration Date, or who cannot complete the procedure for book-entry transfer on a timely basis, may tender their Old Certificates pursuant to the guaranteed delivery procedures set forth in "The Exchange Offer -- Guaranteed Delivery Procedures" section of the Prospectus. Pursuant to such procedures: (i) such tender must be made through an Eligible Institution (as defined below),
(ii) prior to the Expiration Date, the Exchange Agent must receive from such Eligible Institution a properly completed and duly executed Letter of Transmittal (or facsimile thereof) and Notice of Guaranteed Delivery, substantially in the form provided by the Company by facsimile transmission, mail or hand delivery, setting forth the name and address of the holder of


-13-

Old Certificates and the amount of Old Certificates tendered, stating that the tender is being made thereby and guaranteeing that within three New York Stock Exchange ("NYSE") trading days after the date of execution of the Notice of Guaranteed Delivery, the certificates for all physically tendered Old Certificates, or a Book-Entry Confirmation, as the case may be, and any other documents required by this Letter will be deposited by the Eligible Institution with the Exchange Agent, and (iii) the certificates for all physically tendered Old Certificates, in proper form for transfer, or Book-Entry Confirmation, as the case may be, and all other documents required by this Letter, are received by the Exchange Agent within three NYSE trading days after the date of execution of the Notice of Guaranteed Delivery.

The method of delivery of this Letter, the Old Certificates and all other required documents is at the election and risk of the tendering holders, but the delivery will be deemed made only when actually received or confirmed by the Exchange Agent. If Old Certificates are sent by mail, it is suggested that the mailing be made sufficiently in advance of the Expiration Date to permit delivery to the Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration Date.

See "The Exchange Offer" section of the Prospectus.

2. Partial Tenders (not applicable to holders of Old Certificates who tender by book-entry transfer).

If less than all of the Old Certificates evidenced by a submitted certificate are to be tendered, the tendering holder(s) should fill in the aggregate principal amount of Old Certificates to be tendered in the box above entitled "Description of Old Certificates -- Principal Amount Tendered." A reissued certificate representing the balance of nontendered Old Certificates will be sent to such tendering holder, unless otherwise provided in the appropriate box on this Letter, promptly after the Expiration Date. All of the Old Certificates delivered to the Exchange Agent will be deemed to have been tendered unless otherwise indicated.

3. Signatures of this Letter; Bond Powers and Endorsements; Guarantee of Signatures.

If this Letter is signed by the registered holder of the Old Certificates tendered hereby, the signature must


-14-

correspond exactly with the name as written on the face of the certificates without any change whatsoever.

If any tendered Old Certificates are owned of record by two or more joint owners, all such owners must sign this Letter.

If any tendered Old Certificates are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate copies of this Letter as there are different registrations of certificates.

When this Letter is signed by the registered holder of the Old Certificates specified herein and tendered hereby, no endorsements of certificates or separate bond powers are required. If, however, the New Certificates are to be issued, or any untendered Old Certificates are to be reissued, to a person other than the registered holder, then endorsements of any certificates transmitted hereby or separate bond powers are required. Signatures on such certificates must be guaranteed by an Eligible Institution.

If this Letter is signed by a person other than the registered holder of any certificates specified herein, such certificates must be endorsed or accompanied by appropriate bond powers, in either case signed exactly as the name of the registered holder appears on the certificates and the signatures on such certificates must be guaranteed by an Eligible Institution.

If this Letter or any certificates or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and, unless waived by the Company, proper evidence satisfactory to the Company of their authority to so act must be submitted.

Endorsements on certificates for Old Certificates or signatures on bond powers required by this Instruction 3 must be guaranteed by a firm which is a member of a registered national securities exchange or a member of the National Association of Securities Dealers, Inc., by a commercial bank or trust company having an office or correspondent in the United States or by an "eligible guarantor" institution within the meaning of


-15-

Rule 17Ad-15 under the Securities Exchange Act Of 1934 (an "Eligible Institution").

Signatures on this Letter need not be guaranteed by an Eligible Institution, provided the Old Certificates are tendered: (i) by a registered holder of Old Certificates (which term, for purposes of the Exchange Offer, includes any participant in the Book-Entry Transfer Facility system whose name appears on a security position listing as the holder of such Old Certificates) tendered who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on this Letter, or (ii) for the account of an Eligible Institution.

4. Special Issuance and Delivery Instructions.

Tendering holders of Old Certificates should indicate in the applicable box the name and address to which New Certificates issued pursuant to the Exchange Offer and/or substitute certificates evidencing Old Certificates not exchanged are to be issued or sent, if different from the name or address of the person signing this Letter. In the case of issuance in a different name, the employer identification or social security number of the person named must also be indicated. A holder of Old Certificates tendering Old Certificates by book-entry transfer may request that Old certificates not exchanged be credited to such account maintained at the Book-Entry Transfer Facility as such holder of Old Certificates may designate hereon. If no such instructions are given, such Old Certificates not exchanged will be returned to the name or address of the person signing this Letter.

5. Tax Identification Number.

Federal income tax law generally requires that a tendering holder whose Old Certificates are accepted for exchange must provide the Company (as payor) with such Holder's correct Taxpayer Identification Number ("TIN") on Substitute Form W-9 below, which, in the case of a tendering holder who is an individual, is his or her social security number. If the Company is not provided with the current TIN or an adequate basis for an exemption, such tendering holder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, delivery of New Certificates to such tendering holder may be subject to backup withholding in an amount equal to 31% of all


-16-

reportable payments made after the exchange. If withholding results in an overpayment of taxes, a refund may be obtained.

Exempt holders of Old Certificates (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. See the enclosed Guidelines of Certification of Taxpayer Identification Number on Substitute Form W-9 (the "W-9 Guidelines") for additional instructions.

To prevent backup withholding, each tendering holder of Old Certificates must provide its correct TIN by completing the "Substitute Form W-9" set forth below, certifying that the TIN provided is correct (or that such holder is awaiting a TIN) and that (i) the holder is exempt from backup withholding, (ii) the holder has not been notified by the Internal Revenue Service that such holder is subject to a backup withholding as a result of a failure to report all interest or dividends or (iii) the Internal Revenue Service has notified the holder that such holder is no longer subject to backup withholding. If the tendering holder of Old Certificates is a nonresident alien or foreign entity not subject to backup withholding, such holder must give the Company a completed Form W-8, Certificate of Foreign Status. These forms may be obtained from the Exchange Agent. If the Old Certificates are in more than one name or are not in the name of the actual owner, such holder should consult the W-9 Guidelines for information on which TIN to report. If such holder does not have a TIN, such holder should consult the W-9 Guidelines for instructions on applying for a TIN, check the box in Part 2 of the Substitute Form W-9 and write "applied for" in lieu of its TIN. Note: checking this box and writing "applied for" on the form means that such holder has already applied for a TIN or that such holder intends to apply for one in the near future. If such holder does not provide its TIN to the Company within 60 days, backup withholding will begin and continue until such holder furnishes its TIN to the Company.

6. Transfer Taxes.

The Company will pay all transfer taxes, if any, applicable to the transfer of Old Certificates to it or its order pursuant to the Exchange Offer. If, however, New Certificates and/or substitute Old Certificates not exchanged are to be delivered to, or are to be registered or issued in the name of,


-17-

any person other than the registered holder of the Old Certificates tendered hereby, or if tendered Old Certificates are registered in the name of any person other than the person signing this Letter, or if a transfer tax is imposed for any reason other than the transfer of Old Certificates to the Company or its order pursuant to the Exchange Offer, the amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted herewith, the amount of such transfer taxes will be billed directly to such tendering holder.

Except as provided in this Instruction 6, it is not necessary for transfer tax stamps to be affixed to the Old Certificates specified in this Letter.

7. Waiver of Conditions.

The Company reserves the absolute right to waive satisfaction of any or all conditions enumerated in the Prospectus.

8. No Conditional Tenders.

No alternative, conditional, irregular or contingent tenders will be accepted. All tendering holders of Old Certificates, by execution of this Letter, shall waive any right to receive notice of the acceptance of their Old Certificates for exchange.

Neither the Company, the Exchange Agent nor any other person is obligated to give notice of any defect or irregularity with respect to any tender of Old Certificates nor shall any of them incur any liability for failure to give any such notice.

9. Mutilated, Lost, Stolen or Destroyed Old Certificates.

Any holder whose Old Certificates have been mutilated, lost, stolen or destroyed should contact the Exchange Agent at the address indicated above for further instructions.

10. Requests for Assistance or Additional Copies.

Questions relating to the procedure for tendering, as well as requests for additional copies of the Prospectus and this Letter, may be directed to the Exchange Agent, at the address and telephone number indicated above.
