The Class B Certificates will be deemed to be purchased on the date payment of the purchase price is made notwithstanding the failure of any Class B Certificateholder to deliver any Class B Certificate and, upon such a purchase, (i) the selling Class B Certificateholders shall have no further rights with respect to the Class B Certificates and (ii) if the purchaser(s) shall so request, each such Class B Certificateholder will comply with all the provisions of Section 3.04 of the Basic Agreement and the applicable provisions of this Trust Supplement to enable new Class B Certificates to be issued to the purchaser(s) in such denominations otherwise authorized under this Agreement as it shall request.

For the avoidance of doubt, if a Certificate Buy-Out Event ceases to exist and another Certificate Buy-Out Event occurs and is continuing, the purchase rights set forth in this Section 6.01 shall be revived notwithstanding any exercise of such rights during the continuance of any preceding Certificate Buy-Out Event.

Each issue of the Equipment Notes will be secured by, among other things, a security interest in the Aircraft owned by the Company.

The Certificates represent Fractional Undivided Interests in the Trust and the Trust Property, and will have no rights, benefits or interest in respect of any other separate trust established pursuant to the terms of the Basic Agreement for any other series of certificates issued pursuant thereto.

Subject to and in accordance with the terms of the Agreement and the Intercreditor Agreement, from funds then available to the Trustee, there will be distributed on each April 15 and each October 15 (each, a “ Regular Distribution Date ”), commencing on April 15, 2018, to the Person in whose name this Certificate is registered at the close of business on the 15 ^th day preceding the applicable Regular Distribution Date, an amount in respect of the Scheduled Payments on the Series B Equipment Notes due on such Regular Distribution Date, the receipt of which has been confirmed by the Trustee, equal to the product of the percentage interest in the Trust evidenced by this Certificate and an amount equal to the sum of such Scheduled Payments. Subject to and in accordance with the terms of the Agreement and the Intercreditor Agreement, in the event that Special Payments on the Series B Equipment Notes are received by the Trustee, from funds then available to the Trustee, there shall be distributed on the applicable Special Distribution Date, to the Person in whose name this Certificate is registered at the close of business on the 15 ^th day preceding the applicable Special Distribution Date, an amount in respect of such Special Payments on the Series B Equipment Notes, the receipt of which has been confirmed by the Trustee, equal to the product of the percentage interest in the Trust evidenced by this Certificate and an amount equal to the sum of such Special Payments so received. If a Regular Distribution Date or Special Distribution Date is not a Business Day, distribution shall be made on the immediately following Business Day and no interest shall accrue during the intervening period. The Trustee shall mail notice of each Special Payment and the Special Distribution Date therefor to the Certificateholder of this Certificate.

Distributions on this Certificate will be made by the Trustee by check mailed to the Person entitled thereto, without the presentation or surrender of this Certificate or the making of any notation hereon, except that with respect to Certificates registered on the Record Date in the name of a Clearing Agency (or its nominee), such distributions shall be made by wire transfer. Except as otherwise provided in the Agreement and notwithstanding the above, the final distribution on this Certificate will be made after notice mailed by the Trustee of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency of the Trustee specified in such notice.

The Certificates do not represent a direct obligation of, or an obligation guaranteed by, or an interest in, the Company, the Trustee, the Subordination Agent, any Loan Trustee or any Affiliate of any thereof. The Certificates are limited in right of payment, all as more specifically set forth on the face hereof and in the Agreement. All payments or distributions made to Certificateholders under the Agreement shall be made only from the Trust Property and only to the extent that the Trustee shall have sufficient income or proceeds from the Trust Property to make such payments in accordance with the terms of the Agreement. Each Certificateholder of this Certificate, by its acceptance hereof, agrees that it will look solely to the income and proceeds from the Trust Property to the extent available for any payment or distribution to such Certificateholder pursuant to the terms of the Agreement and that it will not have any recourse to the Company, the Trustee, the Loan Trustees or any Affiliate of any thereof except as otherwise expressly provided in the Agreement, in any Note Document or in the Intercreditor Agreement. This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for information with respect to the interests, rights, benefits, obligations, proceeds and duties evidenced hereby. A copy of the Agreement may be examined during normal business hours at the principal office of the Trustee, and at such other places, if any, designated by the Trustee, by any Certificateholder upon request.

The Agreement permits, with certain exceptions therein provided, the amendment thereof, and the modification of the rights and obligations of the Company and the rights of the Certificateholders under the Agreement, at any time by the Company and the Trustee with the consent of the Certificateholders holding Certificates evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the Trust. Any such consent by the Certificateholder of this Certificate shall be conclusive and binding on such Certificateholder and upon all future Certificateholders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Certificateholders of any of the Certificates.

As provided in the Agreement and subject to certain limitations set forth therein, the transfer of this Certificate is registrable in the Register upon surrender of this Certificate for registration of transfer at the offices or agencies maintained by the Trustee in its capacity as Registrar, or by any successor Registrar, duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Registrar, duly executed by the Certificateholder hereof or such Certificateholder’s attorney duly authorized in writing, and thereupon one or more new Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the Trust will be issued to the designated transferee or transferees.

The Certificates are issuable only as registered Certificates without coupons in minimum denominations of $2,000 (or such other denomination that is the lowest integral multiple of $1,000 that is, at the time of issuance, equal to at least 1,000 euros) Fractional Undivided Interest and integral multiples of $1,000 in excess thereof except that one Certificate may be issued in a different denomination. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the Trust, as requested by the Certificateholder surrendering the same.

No service charge will be made for any such registration of transfer or exchange, but the Trustee shall require payment of a sum sufficient to cover any tax or governmental charge payable in connection therewith.

The Company, the Trustee, the Registrar and any Paying Agent shall deem and treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Company, the Trustee, the Registrar or any such agent shall be affected by any notice to the contrary.

Each Certificateholder and Person with a beneficial interest herein, by its acceptance of this Certificate or such interest, agrees to treat the Trust as a grantor trust for all U.S. federal, state and local income tax purposes.

The obligations and responsibilities created by the Agreement and the Trust created thereby shall terminate upon the distribution to Certificateholders of all amounts required to be distributed to them pursuant to the Agreement and the disposition of all property held as part of the Trust Property.

Any Person acquiring or accepting this Certificate or an interest herein will, by such acquisition or acceptance, be deemed to (a) represent and warrant to the Company, the Loan Trustees and the Trustee that either: (i) no assets of a Plan or any trust established with respect to a Plan have been used to purchase or hold this Certificate or an interest herein or (ii) the purchase and holding of this Certificate or interest herein by such Person are exempt from the prohibited transaction restrictions of ERISA and the Code or provisions of Similar Law pursuant to one or more prohibited transaction statutory or administrative exemptions or similar exemptions under Similar Law; and (b) direct the Trustee to invest the assets held in the Trust pursuant to, and take all other actions contemplated by, the terms and conditions of the Basic Agreement, this Trust Supplement, the Intercreditor Agreement, the NPA and each Participation Agreement.

THIS CERTIFICATE AND THE AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.

Unless the certificate of authentication hereon has been executed by the Trustee, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly executed.

SAMPLE OFFERING DOCUMENT LANGUAGE

DESCRIBING BOOK-ENTRY-ONLY ISSUANCE

(Prepared by DTC–bracketed material may be applicable only to certain issues)

1.    The Depository Trust Company (“DTC”), New York, NY, will act as securities depository for the securities (the “Securities”). The Securities will be issued as fully-registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered Security certificate will be issued for [each issue of] the Securities, [each] in the aggregate principal amount of such issue, and will be deposited with DTC. [If, however, the aggregate principal amount of [any] issue exceeds $500 million, one certificate will be issued with respect to each $500 million of principal amount, and an additional certificate will be issued with respect to any remaining principal amount of such issue.]

2.    DTC, the world’s largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, 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 New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has a Standard & Poor’s rating of AA+. The DTC Rules applicable to its Participants are on file with the Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com .

3.    Purchases of Securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the Securities on DTC’s records. The ownership interest of each actual purchaser of each Security (“Beneficial Owner ”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Securities are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in Securities, except in the event that use of the book-entry system for the Securities is discontinued.

(to Issuer Letter of Representations)

4.    To facilitate subsequent transfers, all Securities deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of Securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Securities; DTC’s records reflect only the identity of the Direct Participants to whose accounts such Securities are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

5.    Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. [Beneficial Owners of Securities may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the Securities, such as redemptions, tenders, defaults, and proposed amendments to the Security documents. For example, Beneficial Owners of Securities may wish to ascertain that the nominee holding the Securities for their benefit has agreed to obtain and transmit notices to Beneficial Owners. In the alternative, Beneficial Owners may wish to provide their names and addresses to the registrar and request that copies of notices be provided directly to them.]

6.    [Redemption notices shall be sent to DTC. If less than all of the Securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.]

7.    Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to Securities unless authorized by a Direct Participant in accordance with DTC’s MMI Procedures. Under its usual procedures, DTC mails an Omnibus Proxy to Issuer as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts Securities are credited on the record date (identified in a listing attached to the Omnibus Proxy).

8.    Redemption proceeds, distributions, and dividend payments on the Securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from Issuer or Agent, on payable date in accordance with their respective holdings shown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC, Agent, or Issuer, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and dividend payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of Issuer or Agent, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

(to Issuer Letter of Representations)

9.    [A Beneficial Owner shall give notice to elect to have its Securities purchased or tendered, through its Participant, to [ Tender/Remarketing] Agent, and shall effect delivery of such Securities by causing the Direct Participant to transfer the Participant’s interest in the Securities, on DTC’s records, to [Tender/Remarketing] Agent. The requirement for physical delivery of Securities in connection with an optional tender or a mandatory purchase will be deemed satisfied when the ownership rights in the Securities are transferred by Direct Participants on DTC’s records and followed by a book-entry credit of tendered Securities to [Tender/Remarketing] Agent’s DTC account.]

10.    DTC may discontinue providing its services as depository with respect to the Securities at any time by giving reasonable notice to Issuer or Agent. Under such circumstances, in the event that a successor depository is not obtained, Security certificates are required to be printed and delivered.

11.    Issuer may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, Security certificates will be printed and delivered to DTC.

12.    The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that Issuer believes to be reliable, but Issuer takes no responsibility for the accuracy thereof.

After the occurrence of a Downgrade Event with respect to any Liquidity Provider, each Liquidity Facility provided by such Liquidity Provider shall become a “ Downgraded Facility ” on the thirty-fifth (35th) day after the related Downgrade Date, unless, not later than such thirty-fifth (35th) day (or, if earlier, the expiration date of such Downgraded Facility), the Rating Agency whose downgrading of such Liquidity Provider resulted in such Downgrade Event shall have provided a written confirmation to the effect that the occurrence of such Downgrade Event will not result in the downgrading, withdrawal or suspension of the ratings then issued by such Rating Agency of the related Class of Certificates. Notwithstanding the foregoing, if at any time after the occurrence of such Downgrade Event, such Liquidity Provider notifies the Subordination Agent in writing that no such confirmation will be provided by such Rating Agency, each Liquidity Facility provided by such Liquidity Provider shall become a Downgraded Facility as of the date of such notice to the Subordination Agent.

(iii) If a Downgraded Facility has not been replaced by a Replacement Liquidity Facility in accordance with Section 3.05(c)(ii), the Subordination Agent shall, on the 35th day referred to in Section 3.05(c)(ii) (or if such 35th 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 the Available Amount thereunder.

Subject to Section  3.05(e)(iii) , the applicable 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 such Liquidity Provider.

(iv) For the avoidance of doubt, the provisions of this Section  3.05(c) shall apply to each occurrence of a Downgrade Event with respect to a Liquidity Provider, regardless of whether or not one or more Downgrade Events have occurred prior thereto and whether or not any confirmation by a Rating Agency specified in Section  3.05(c)(i) has been obtained with respect to any prior occurrence of a Downgrade Event.

If 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 fifteen (15) days after the Final Legal Distribution Date for such Class of Certificates, then, if before the 25th day prior to any anniversary date of the Class AA/A Closing Date (in the case of the Class AA Liquidity Facility and the Class A Liquidity Facility) or the Class B Closing Date (in the case of the Class B Liquidity Facility) (such 25th day, the “ Notice Date ”) the Liquidity Provider shall have advised the Subordination Agent that such Liquidity Facility shall not be extended beyond the immediately following anniversary date of the Class AA/A Closing Date (in the case of the Class AA Liquidity Facility and the Class A Liquidity Facility) or the Class B Closing Date (in the case of the Class B Liquidity Facility) and on or before the Notice Date such Liquidity Facility shall not have been replaced in accordance with Section  3.05(e) , the Subordination Agent shall, on the Notice Date (or as soon thereafter as possible but prior to the date of expiration of the expiring Liquidity Facility (a “ Non-Extended Facility ”)), in accordance with the terms of such Non-Extended Facility, request a drawing under such Non-Extended Facility (such drawing, a “ Non-Extension Drawing ”) of all available and undrawn amounts thereunder.

(e) Issuance of Replacement Liquidity Facility . (i) Subject to Section 3.05(e)(iii) and the agreements, if any, in the applicable Fee Letter, at any time, American may, at its option and at its own expense, 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  3.05(e)(ii) ); provided , however , that if the initial Liquidity Provider is replaced (including as a result of a refinancing of the Class A Certificates or the Class B Certificates) it shall be replaced with respect to all Liquidity Facilities under which it is a Liquidity Provider. If such Replacement Liquidity Facility is provided at any time after a Downgrade Drawing, a Non-Extension Drawing or a Special Termination Drawing has been made, all funds on deposit in the relevant Cash Collateral Account resulting from such Downgrade Drawing, Non-Extension Drawing or Special Termination Drawing will be returned to the Liquidity Provider being replaced.

(ii) If any Liquidity Provider shall determine not to extend its Liquidity Facility in accordance with Section  3.05(d) , then such Liquidity Provider may, at its option and its own expense, arrange for a Replacement Liquidity Facility to replace such Liquidity Facility during the period no earlier than forty (40) days and no later than twenty-five (25) days prior to the then effective Stated Expiration Date of such Liquidity Facility. At any time after a Non-Extension Drawing has been made under any Liquidity Facility, the Liquidity Provider thereunder may, at its option and its own expense, arrange for a Replacement Liquidity Facility to replace the Liquidity Facility under which such Non-Extension Drawing has been made.

38

(iii) No Replacement Liquidity Facility arranged by American or a Liquidity Provider in accordance with clause  (i) or (ii)  above or pursuant to Section 3.05(c) , respectively, shall become effective and no such Replacement Liquidity Facility shall be deemed a “Liquidity Facility” under the Operative Agreements, unless and until (A) each of the conditions referred to in sub-clauses (iv)(x) and (z)  below shall have been satisfied, (B) if such Replacement Liquidity Facility shall materially adversely affect the rights, remedies, interests or obligations of the Class AA Certificateholders, the Class A Certificateholders or the Class B 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 3.05(e)(ii) or pursuant to Section 3.05(c) , such Replacement Liquidity Facility is reasonably acceptable to American.

(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, withdrawal or suspension of any rating then in effect for the related Class of Certificates by such Rating Agency (without regard to any downgrading of any rating of the Liquidity Provider being replaced pursuant to Section  3.05(c) ), (y) pay all Liquidity Obligations then owing to the replaced Liquidity Provider (which payment shall be made first from available funds in the applicable Cash Collateral Account as described in Section  3.05(f) , 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  3.05(e) with respect to a Replacement Liquidity Facility, (1) the replaced Liquidity Facility shall terminate, (2) the Subordination Agent shall, if and to the extent so requested by American 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, (3) each of the parties hereto shall enter into any amendments to this Agreement necessary to give effect to (a) the replacement of the applicable Liquidity Provider with the applicable Replacement Liquidity Provider and (b) the replacement of the applicable Liquidity Facility with the applicable Replacement Liquidity Facility, and (4) 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.

EXERCISE OF REMEDIES

Section 4.01. 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, as the holder of the Equipment Notes issued under such Indenture, which in turn shall direct the Loan Trustee under such Indenture, in the exercise of remedies available to the holders of such Equipment Notes, including, without limitation, the ability to vote all such Equipment Notes held by the Subordination Agent in favor of Accelerating such Equipment Notes in accordance with the provisions of such Indenture. Subject to Section  4.01(a)(iii) , if the Equipment Notes issued pursuant to any Indenture have been Accelerated following an Indenture Event of Default with respect thereto, the Controlling Party may direct the Subordination Agent to sell, 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 the Controlling Party may reasonably deem advisable and in accordance with applicable law.

(ii) Following the occurrence and during the continuation of an Indenture Event of Default under any Indenture, in the exercise of remedies pursuant to such Indenture, the Loan Trustee under such Indenture may be directed to lease the related Aircraft to any Person (including American) so long as the Loan Trustee in doing so acts in a “commercially reasonable” manner within the meaning of Article 9 of the Uniform Commercial Code as in effect in any applicable jurisdiction (including Sections 9-610 and 9-627 thereof).

(iii) 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 an American Bankruptcy Event, without the consent of each Trustee (other than the Trustee of any Trust all of the Certificates of which are held or beneficially owned by American and/or its Affiliates), 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.

(iv) Upon the occurrence and continuation of an Indenture Event of Default under any Indenture, the Subordination Agent will obtain three desktop appraisals from the Appraisers selected by the Controlling Party setting forth the current market value, current lease rate and distressed value (in each case, as defined by the International Society of Transport Aircraft Trading or any successor organization) of the Aircraft subject to such Indenture (each

44

such appraisal, an “ Appraisal ” and the current market value appraisals being referred to herein as the “ Post-Default Appraisals ”). For so long as any Indenture Event of Default shall be continuing under any Indenture, and without limiting the right of the Controlling Party to request more frequent Appraisals, the Subordination Agent will obtain updated Appraisals on the date that is 364 days from the date of the most recent Appraisal (or if an American Bankruptcy Event shall have occurred and is continuing, on the date that is 180 days from the date of the most recent Appraisal) and shall (acting on behalf of each Trustee) post such Appraisals on DTC’s Internet bulletin board or make such other commercially reasonable efforts as the Subordination Agent may deem appropriate to make such Appraisals available to all Certificateholders.

(b) Following the occurrence and during the continuance of an Indenture Event of Default under any Indenture, the Controlling Party shall take such actions as it may reasonably deem most effectual to complete the sale or other disposition of the relevant Aircraft or Equipment Notes. In addition, in lieu of any sale, assignment, contract to sell or other disposition, the Controlling Party may maintain or cause the Subordination Agent to 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 direct the Subordination Agent to, 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 or to take any other remedial action permitted under such Indenture or under any applicable law.

(c) If following an American Bankruptcy Event and during the pendency thereof, the Controlling Party receives a proposal from or on behalf of American to restructure the financing of any one or more of the Aircraft, the Controlling Party shall promptly thereafter give the Subordination Agent, each Trustee and each Liquidity Provider that has not made a Final Drawing notice of the material economic terms and conditions of such restructuring proposal whereupon the Subordination Agent acting on behalf of each Trustee shall post such terms and conditions of such restructuring proposal on DTC’s Internet bulletin board or make such other commercially reasonable efforts as the Subordination Agent may deem appropriate to make such terms and conditions available to all Certificateholders. Thereafter, neither the Subordination Agent nor any Trustee, whether acting on instructions of the Controlling Party or otherwise, may, without the consent of each Trustee and each Liquidity Provider that has not made a Final Drawing, enter into any term sheet, stipulation or other agreement (a “ Restructuring Arrangement ”) (whether in the form of an adequate protection stipulation, an extension under Section 1110(b) of the Bankruptcy Code or otherwise) to effect any such restructuring proposal with or on behalf of American unless and until the material economic terms and conditions of such restructuring proposal shall have been made available to all Certificateholders and each Liquidity Provider that has not made a Final Drawing for a period of not less than fifteen (15) calendar days (except that such requirement shall not apply to any such term sheet, stipulation or other agreement that is to be effective on or as of any date occurring during the 60-Day Period and that is initially effective for a period not exceeding three months from the expiry of the 60-Day Period (an “ Interim Restructuring Arrangement ”)). The foregoing provisions of this Section 4.01(c) : (i) shall not apply to any extension of a Restructuring Arrangement with respect to which such provisions have been complied with in connection with the original entry thereof if

45

the possibility of such extension has been disclosed in satisfaction of the notification requirements of such provisions and such extension shall not amend or modify any of the other terms and conditions of such Restructuring Arrangement and (ii) shall apply to the initial extension of an Interim Restructuring Arrangement beyond the three months following the expiry of the 60-Day Period but not to any subsequent extension of such Interim Restructuring Arrangement, if the possibility of such subsequent extension has been disclosed in satisfaction of the notification requirements of such provisions and such subsequent extension shall not amend or modify any of the other terms and conditions of such Interim Restructuring Arrangement. In the event that any Certificateholder gives irrevocable notice of the exercise of its right to purchase all (but not less than all) of the Class of Certificates represented by the then Controlling Party pursuant to the applicable Trust Agreement, prior to the expiry of the 15-day notice period specified above, such Controlling Party may not direct the Subordination Agent or any Trustee to enter into any such restructuring proposal with respect to any of the Aircraft, unless and until such Certificateholder shall fail to purchase such Class of Certificates on the date that it is required to make such purchase.

Section 4.02. Remedies Cumulative . To the extent permitted by applicable law, 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 right, 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, to the extent permitted by applicable law, impair any such right, power or remedy or be construed to be a waiver of any default or to be an acquiescence therein.

Section 4.03. 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.

Section 4.04. Right of Certificateholders and the Liquidity Providers 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  3.02 ) 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.

The Controlling Party or American (only so long as no Indenture Event of Default has occurred or is continuing) may remove the Subordination Agent for cause by so notifying the Subordination Agent and may appoint a successor Subordination Agent. The Controlling Party (or the party that would be the Controlling Party if an Indenture Event of Default had occurred) shall remove the Subordination Agent if:

(3) a receiver of the Subordination Agent shall be appointed or any public officer shall take charge or control of the Subordination Agent or its property or affairs for the purpose of rehabilitation, conservation or liquidation; or

(4) the Subordination Agent otherwise becomes incapable of acting.

If the Subordination Agent resigns or is removed or if a vacancy exists in the office of Subordination Agent for any reason (the Subordination Agent in such event being referred to herein as the retiring Subordination Agent), the Controlling Party (or the party that would be the Controlling Party if an Indenture Event of Default had occurred) shall promptly appoint a successor Subordination Agent. If a successor Subordination Agent shall not have been appointed within sixty (60) days after such notice of resignation or removal, the retiring Subordination Agent, one or more of the Trustees or one or more of the Liquidity Providers may petition any court of competent jurisdiction for the appointment of a successor Subordination Agent to act until such time, if any, as a successor shall have been appointed as provided above.

A successor Subordination Agent shall deliver (x) a written acceptance of its appointment as Subordination Agent hereunder to the retiring Subordination Agent and (y) a written assumption of its obligations hereunder and under each Liquidity Facility to each party hereto, upon which the resignation or removal of the retiring Subordination Agent shall become effective, and the successor Subordination Agent shall have all the rights, powers and duties of the Subordination Agent under this Agreement.

Notwithstanding the foregoing, no resignation or removal of the Subordination Agent shall be effective unless and until a successor has been appointed. No appointment of a successor Subordination Agent shall be effective unless and until the Rating Agencies shall have delivered a Ratings Confirmation with respect to each Class of Certificates then rated by the Rating Agencies.

Each of the Liquidity Providers hereby agrees and confirms that it shall be deemed to consent to any issuance and amendment in accordance with this Section 8.01(c) (subject to the Liquidity Providers’ consent right in Section 8.01(c)(iii) ) and that any such issuance and amendment shall not affect any of its respective obligations under the applicable Liquidity Facility.

(v) the Additional Certificates may be rated by the Rating Agencies;
