Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depositary (or its nominee).

(b) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Note may be transferred in accordance with Section 2.15 and the rules and procedures of the Depositary. In addition, certificated Notes shall be transferred to beneficial owners in exchange for their beneficial interests only if (i) the Depositary notifies the Issuer that it is unwilling or unable to continue as Depositary for the Global Notes and a successor depositary is not appointed by the Issuer within ninety (90) days of such notice or (ii) there shall have occurred and be continuing an Event of Default and the Depositary shall have requested the issuance of certificated Notes.

(f) At such time as all beneficial interests in Global Notes have been exchanged for certificated Notes, redeemed, repurchased or cancelled, all Global Notes shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.11. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for certificated Notes, redeemed, repurchased or cancelled, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note, by the Trustee or the Note Custodian, at the direction of the Trustee, to reflect such reduction.

(g) General Provisions Relating to Transfers and Exchanges .

(1) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes and certificated Notes at the Registrar’s request.

(2) No service charge shall be made to a Holder for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any stamp or transfer tax or similar governmental charge payable in connection therewith (other than any such stamp or transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Section 2.10, Section 2.16, Section 3.6, Section 4.10, Section 4.14 and Section 9.4 hereof).

39

(3) All Global Notes and certificated Notes issued upon any registration of transfer or exchange of Global Notes or certificated Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes (or interests therein) or certificated Notes surrendered upon such registration of transfer or exchange.

(4) The Registrar is not required (A) to issue, to register the transfer of or to exchange Notes during a period beginning at the opening of business fifteen (15) days before the day of any selection of Notes for redemption and ending at the close of business on the day of such selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

(5) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent, or the Issuer shall be affected by notice to the contrary.

(6) The Trustee shall authenticate Global Notes and certificated Notes in accordance with the provisions of Section 2.2. Except as provided in Section 2.6(b), neither the Trustee nor the Registrar shall authenticate or deliver any certificated Note in exchange for a Global Note.

(7) Neither the Trustee nor any Agent shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(8) Each Holder agrees to indemnify the Issuer and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Note in violation of any provision of this Indenture and/or applicable United States Federal or state securities law.

SECTION 2.7. Replacement Notes . If any mutilated Note is surrendered to the Trustee, or the Issuer and the Trustee receive evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon the written order of the Issuer signed by an Officer of the Issuer, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond must be

40

supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer, the Trustee and the Agents may charge for their expenses in replacing a Note.

Every replacement Note is an additional obligation of the Issuer and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

SECTION 2.8. Outstanding Notes . The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.8 as not outstanding. Except as set forth in Section 2.9, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

If a Note is replaced pursuant to Section 2.7, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, on or after the maturity date, any redemption date or date for purchase of the Notes pursuant to an offer to purchase, money sufficient to pay the amounts under the Notes payable on such date, then on and after that date such Notes payable on such date shall be deemed to be no longer outstanding and shall cease to accrue interest.

SECTION 2.9. Treasury Notes . In determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or by any Affiliate of the Issuer shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes of which a Responsible Officer of the Trustee has written notice as being so owned shall be so disregarded. Notwithstanding the foregoing, Notes that are to be acquired by the Issuer or an Affiliate of the Issuer pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by such entity until legal title to such Notes passes to such entity.

SECTION 2.10. Temporary Notes . Until certificated Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Issuer signed by one Officer of the Issuer. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall upon receipt of a written order of the Issuer signed by one Officer, authenticate certificated Notes in certificate form in exchange for temporary Notes.

Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

SECTION 2.11. Cancellation . The Issuer at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder or which the Issuer may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled

41

by the Trustee. All Notes surrendered for registration of transfer, exchange or payment, if surrendered to any Person other than the Trustee, shall be delivered to the Trustee. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation. Subject to Section 2.7, the Issuer may not issue new Notes to replace Notes that it has redeemed or paid or that have been delivered to the Trustee for cancellation. All cancelled Notes held by the Trustee shall be disposed of in accordance with its customary practice, and certification of their disposal delivered to the Issuer upon its written request therefor.

SECTION 2.12. Defaulted Interest . If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which date shall be the earliest practicable date but in all events at least five (5) Business Days prior to the payment date, in each case at the rate provided in the Notes and in Section 4.1. The Issuer shall fix or cause to be fixed each such special record date and payment date and shall promptly thereafter notify the Trustee of any such date. At least fifteen (15) days before the special record date, the Issuer (or the Trustee, in the name and at the expense of the Issuer) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

SECTION 2.13. Computation of Interest . Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

SECTION 2.14. CUSIP Number . The Issuer in issuing the Notes may use a “CUSIP” number, and if it does so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify the Trustee in writing of any change in any CUSIP number.

SECTION 2.15. Special Transfer Provisions . Each Note issued pursuant to an exemption from registration under the Securities Act (other than in reliance on Regulation S) will constitute a Transfer Restricted Note and be required to bear the Restricted Notes Legend until the date that is one year after the later of the date of original issue and the last date on which the Issuer or any affiliate (within the meaning of Rule 405 under the Securities Act) of the Issuer was the owner of such Notes (or any predecessor thereto), unless and until such Transfer Restricted Note is transferred or exchanged pursuant to an effective registration statement under the Securities Act.

The Issuer shall provide written notice to the Trustee of the date that constitutes the final day of the Restricted Period in respect of any Notes issued in reliance on Regulation S; provided , however , that no such notice shall be required with respect to any Initial Notes issued in reliance on Regulation S and May 26, 2014 shall constitute the final day of the Restricted Period for such Initial Notes.

(ii) If the proposed transferee is a Participant and the Note to be transferred consists of an interest in the Regulation S Global Note, upon receipt by the Registrar of (x) the items required by paragraph (i) above and (y) instructions given in accordance with the Depositary’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Rule 144A Global Note in an amount equal to the principal amount of the beneficial interest in the Regulation S Global Note to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of such Regulation S Global Note in an amount equal to the principal amount of the beneficial interest in such Regulation S Global Note to be so transferred.

(b) Transfers Pursuant to Regulation S . The following provisions shall apply with respect to registration of any proposed transfer of a Transfer Restricted Note pursuant to Regulation S:

43

(c) In the event that a Global Note is exchanged for Notes in certificated, registered form pursuant to Section 2.6, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of clauses (a) and (b) above (including the certification requirements intended to ensure that such transfers comply with Rule 144A or Regulation S, as the case may be) and such other procedures as may from time to time be adopted by the Issuer and notified to the Trustee in writing.

(d) Restricted Notes Legend . Upon the transfer, exchange or replacement of Notes not bearing the Restricted Notes Legend, the Registrar shall deliver Notes that do not bear the Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes bearing the Restricted Notes Legend, the Registrar shall deliver only Notes that bear the Restricted Notes Legend unless there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Issuer 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 Note bearing the Restricted Notes Legend or the Regulation S Legend, as applicable, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Restricted Notes Legend or the Regulation S Legend, as applicable, and agrees that it shall transfer such Note only as provided in this Indenture. A transfer of a beneficial interest in a Global Note that does not involve an exchange of such interest for a certificated Note or a beneficial interest in another Global Note shall be subject to compliance with applicable law and the applicable procedures of the Depositary but is not subject to any procedure required by this Indenture.

In connection with any proposed transfer pursuant to Regulation S or pursuant to any other available exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A), the Issuer may require the delivery of an Opinion of Counsel, other certifications or other information satisfactory to the Issuer.

The Registrar shall retain copies of all letters, notices and other written communications received pursuant to this Section 2.15.

SECTION 2.16. Issuance of Additional Notes . The Issuer shall be entitled to issue Additional Notes in an unlimited aggregate principal amount under this Indenture that shall have identical terms as the Initial Notes, other than with respect to the date of issuance, issue price,

44

amount of interest payable on the first interest payment date applicable thereto and transfer restrictions; provided that such issuance is not prohibited by the terms of this Indenture, including Section 4.9 and Section 4.12, provided further that Additional Notes will not be issued with the same CUSIP, if any, as any Notes then existing unless such Additional Notes are fungible with such Notes then existing for U.S. federal income tax purposes. The Initial Notes and any Additional Notes shall be treated as a single class for all purposes under this Indenture.

With respect to any Additional Notes, the Issuer shall set forth in a resolution of its Board of Directors and in an Officers’ Certificate, a copy of each of which shall be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

(2) the issue price, the issue date, the CUSIP number of such Additional Notes, the first interest payment date and the amount of interest payable on such first interest payment date applicable thereto and the date from which interest shall accrue;

(3) whether such Additional Notes shall be Transfer Restricted Notes; and

(4) that such issuance is not prohibited by this Indenture.

SECTION 2.17. Payment of Additional Amounts .

(1) All payments made by or on behalf of the Issuer under or with respect to the Notes or by or on behalf of any Guarantor pursuant to its Guarantee, will be made without withholding or deduction for or on account of any taxes imposed or levied by or on behalf of any Panamanian taxing authority or any political subdivision or any authority or agency therein or thereof having power to tax, or any other jurisdiction in which the Issuer or any Guarantor (including any successor entity) is organized, incorporated, engaged in business or is otherwise resident or treated as resident for tax purposes, or any jurisdiction from or through which payment is made (including, without limitation, the jurisdiction of each paying agent) (each, a “ Specified Tax Jurisdiction ”), unless required by law or regulation of any such taxing authority. If the Issuer or a Guarantor is obligated to withhold or deduct any amount on account of taxes imposed by any Specified Tax Jurisdiction from any payment made with respect to the Notes, the Issuer or such Guarantor will:

(a) subject to the limitations below, pay to each Holder such additional amounts (“ Additional Amounts ”) as may be necessary so that the net amount received by each Holder (including Additional Amounts) after such withholding or deduction will not be less than the amount such Holder would have received if such taxes had not been withheld or deducted;

45

(b) furnish to the Trustee for the benefit of the Holders, within 60 days after the date payment of any taxes is due pursuant to applicable law, certified copies of an official receipt of the relevant government authorities for all amounts deducted or withheld pursuant to applicable law, or if such receipts are not readily obtainable without significant expense (as reasonably determined by the Issuer), other evidence of payment by the Issuer or such Guarantor of those taxes reasonably satisfactory to the Trustee which the Trustee will make available to the Holders or beneficial owners of Notes upon reasonable request; and

(c) at least 15 days prior to each date on which any Additional Amounts are payable, deliver to the Trustee an Officers’ Certificate setting forth the calculation of the Additional Amounts to be paid and such other information as the Trustee may request to enable the Trustee to pay such Additional Amounts to Holders on the payment date. The Issuer agrees to indemnify the Trustee and each Paying Agent for, and to hold each harmless against, any loss, liability or expense reasonably incurred without bad faith on its part arising out of or in connection with actions taken or omitted by it in reliance on any such Officers’ Certificate or any failure to furnish such a certificate. The obligations of the Issuer hereunder shall survive the payment of the Notes, the resignation or removal of the Trustee or any Paying Agent and/or termination of this Indenture.

(2) Notwithstanding the foregoing, neither the Issuer nor any Guarantor will pay Additional Amounts with respect to a payment made to any Holder or beneficial owner of a Note:

(a) which is subject to such taxes by reason of the Holder or the beneficial owner being a resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some connection with the relevant Specified Tax Jurisdiction otherwise than by the mere acquisition, holding or disposition of the Notes, enforcement of rights hereunder or the receipt of payments thereunder;

(b) for or on account of any taxes imposed or deducted or withheld by reason of the failure of the Holder or beneficial owner of the Notes to complete, execute and deliver to the Issuer or a Guarantor, as the case may be, any customary form or document, to the extent applicable to such Holder or beneficial owner, that may be required by law (including any applicable tax treaty) or by reason of administration of such law and which is reasonably requested in writing to be delivered to the Issuer or such Guarantor in order to enable the Issuer or such Guarantor to make payments on the Notes or pursuant to any Guarantee, as the case may be, without deduction or withholding for taxes, or with deduction or withholding of a lesser amount, which form or document shall be delivered within 60 days of a written request therefor by the Issuer or such Guarantor;

(c) for or on account of any estate, inheritance, gift, sales, transfer, capital gains, excise, personal property or similar tax, assessment or other governmental charge;

46

(d) for or on account of any tax, duty, assessment or other governmental charge that is payable otherwise than by withholding from payments under or with respect to the Notes;

(e) where the payment could have been made without deduction or withholding if the beneficiary of the payment had presented the Note for payment within 30 days after the date on which such payment or such Note became due and payable or the date on which payment thereof is duly provided for, whichever is later;

(f) if the Holder is a fiduciary, partnership or person other than the sole beneficial owner of that payment, to the extent that such payment would be required to be included in income under the laws of the relevant taxing jurisdiction for tax purposes, of a beneficiary or settler with respect to such fiduciary, a member of such partnership or a beneficial owner who, in each case, would not have been entitled to such Additional Amounts had such beneficiary, settler, partner or beneficial owner been the Holder thereof; or

(g) any combination of the instances described in the foregoing clauses (a) through (f).

(3) Any reference in this Indenture or the Notes to the payment of principal, premium, if any, interest, purchase price, redemption price or any other amount payable under or with respect to any Note, will be deemed to include the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. The Issuer’s and the Guarantors’ obligation to make payments of Additional Amounts will survive any termination of this Indenture or the defeasance of any rights hereunder.

(4) The Issuer will promptly pay when due any present or future stamp, issue, registration, documentation, court or similar documentary taxes or any other excise or property taxes, charges or similar levies (including interest and penalties with respect thereto) that arise in a Specified Tax Jurisdiction from the execution, delivery or registration of each Note or any other document or instrument referred to herein or therein.

47

If the Issuer is required to make an offer to purchase Notes pursuant to Section 4.10 or Section 4.14, it shall furnish to the Trustee, at least three (3) Business Days (or such shorter period as is acceptable to the Trustee) prior to the giving of notice of the offer to purchase, an Officers’ Certificate setting forth the (i) section of this Indenture pursuant to which the offer to purchase shall occur, (ii) terms of the offer, (iii) principal amount of Notes to be purchased, (iv) purchase price and (v) purchase date and further setting forth a statement to the effect that (a) the Issuer or one of its Restricted Subsidiaries has effected an Asset Sale and there are Excess Proceeds aggregating an amount equal to or more than $25.0 million or (b) a Change of Control has occurred, as applicable.

SECTION 3.2. Selection of Notes to Be Redeemed . If less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis (subject to the procedures of the Depositary), by lot or by such method as the Trustee, in its sole discretion, may deem fair and appropriate; provided , however that no Notes of $2,000 in original principal amount or less shall be redeemed in part. In addition, if a partial redemption is made pursuant to Section 3.7(c), selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of the Depositary), unless that method is otherwise prohibited.

On and after the redemption date, interest will cease to accrue on Notes or portions of them called for redemption so long as the Issuer has complied with Section 3.5 in connection with such redemption. The Trustee shall make the selection from the Notes outstanding and not previously called for redemption as long as the Issuer has deposited with the Paying Agent funds in satisfaction of the applicable redemption price pursuant to this Indenture and shall promptly notify the Issuer in writing of the Notes selected for redemption.

48

The notice shall identify the Notes (including CUSIP numbers) to be redeemed and shall state:

(1) the redemption date;

(2) the redemption price; provided that, with respect to any redemption pursuant to Section 3.7(a), the redemption price need only be included in the notice of redemption to the extent the redemption price has been determined at the time of such notice of redemption (and if not so determined at such time, the notice of redemption shall then include the manner in which the redemption price will be calculated);

(3) if any Note is being redeemed in part, the portion of the principal amount of such Notes to be redeemed and that, after the redemption date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note will be made, as appropriate);

(4) the name and address of the Trustee;

(5) that Notes called for redemption must be surrendered to the Trustee to collect the redemption price;

(6) that, unless the Issuer defaults in making such redemption payment, interest, if any, on Notes called for redemption ceases to accrue on and after the redemption date;

(8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes; and

(9) if applicable, any conditions to such redemption.

At the Issuer’s written request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense; provided , however , that the Issuer shall have delivered to the Trustee, at least three (3) Business Days prior to the giving of notice of redemption (or such shorter period as is acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in the notice as provided in the preceding paragraph. The notice delivered in the manner herein provided shall be deemed to have been duly given whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note shall not affect the validity of the proceeding for the redemption of any other Note.

SECTION 3.4. Effect of Notice of Redemption . Except with respect to notices of redemption given in accordance with Section 3.7(d), once notice of redemption is delivered in accordance with Section 3.3, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price plus accrued and unpaid interest to (but excluding) such date unless the redemption is subject to a condition precedent that has not been satisfied or waived. Notice of redemption may, at the Issuer’s option and discretion, be subject to one or more conditions precedent as set forth in Section 3.7(f).

SECTION 3.5. Deposit of Redemption Price . On or before 10:00 a.m. (New York City time) on the Business Day prior to each redemption date or the date on which Notes must be accepted for purchase pursuant to Section 4.10 or Section 4.14, the Issuer shall deposit with the

49

Trustee or with the Paying Agent (other than the Issuer or an Affiliate of the Issuer) money sufficient to pay the redemption price of and accrued and unpaid interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption price of (including any applicable premium), and accrued interest, if any, on, all Notes to be redeemed or purchased.

If Notes called for redemption or tendered in a Net Proceeds Offer or Change of Control Offer are paid or if the Issuer has deposited with the Trustee or Paying Agent money sufficient to pay the redemption or purchase price of, and unpaid and accrued interest, if any, on, all Notes to be redeemed or purchased, on and after the redemption or purchase date, interest, if any, shall cease to accrue on the Notes or the portions of Notes called for redemption or tendered and not withdrawn in a Net Proceeds Offer or Change of Control Offer (regardless of whether certificates for such securities are actually surrendered). If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case, at the rate provided in the Notes and in Section 4.1.

SECTION 3.6. Notes Redeemed in Part .

SECTION 4.2. Maintenance of Office or Agency . The Issuer shall maintain an office or agency where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer and Guarantors in respect of the Notes and this Indenture (other than the type contemplated by Section 12.19) may be served. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish to the Trustee the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Issuer hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Issuer in accordance with Section 2.3.

SECTION 4.3. Provision of Financial Information .

Whether or not required by the SEC, so long as any Notes are outstanding, the Issuer will furnish to the Trustee and the Holders, or, to the extent permitted by the SEC, file electronically with the SEC through the SEC’s Electronic Data Gathering, Analysis and Retrieval System (or any successor system) (“ EDGAR ”) within the time periods specified in the SEC’s rules and regulations:

52

(1) all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Issuer were required to file such reports; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Issuer were required to file such reports.

If the Issuer has designated any of its Subsidiaries as Unrestricted Subsidiaries, and such Unrestricted Subsidiaries, individually or taken together, would constitute a Significant Subsidiary of the Issuer, then the quarterly and annual financial information required by this Section 4.3 will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Issuer and its Restricted Subsidiaries excluding the Unrestricted Subsidiaries.

For so long as any Notes remain outstanding and are “restricted securities” within the meaning of Rule 144(A)(3), and the Issuer and the Guarantors are not required to file the reports required by this Section 4.3 with the SEC, the Issuer shall furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

The Issuer will be deemed to have furnished the reports required to be furnished to the Trustee and the Holders pursuant to this Section 4.3 if it has filed such reports with the SEC using the EDGAR filing system or if it has made such reports publicly available on its website.

In the event that:

(i) the rules and regulations of the SEC permit the Issuer and any direct or indirect parent company of the Issuer to report at such parent entity’s level on a consolidated basis and such parent entity of the Issuer is not engaged in any business in any material respect other than incidental to its ownership, directly or indirectly, of the Voting Stock of the Issuer, or

(ii) any direct or indirect parent of the Issuer becomes a Guarantor,

such consolidated reporting at such parent entity’s level in a manner consistent with that described in this covenant for the Issuer will satisfy this covenant; provided that such financial information is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such direct or indirect parent and any of its Subsidiaries other than the Issuer and its Subsidiaries, on the one hand, and the information relating to the Issuer and its Subsidiaries on a stand-alone basis, on the other hand.

The Issuer shall notify the Trustee in writing if the Issuer is not permitted by the SEC to file, or has not filed, electronically with the SEC through EDGAR (or any successor system) the information and reports referred to in clauses (1) and (2) of this Section 4.3. The Trustee shall have no obligation to determine if and when the Issuer’s information is available on the SEC’s website.

53

Delivery of the above reports to the Trustee is for informational purposes only and the Trustee’s receipt of such reports shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants in this Indenture (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates) or any other agreement or document.

SECTION 4.4. Compliance Certificate . The Issuer shall deliver to the Trustee, within 90 days after the end of each fiscal year beginning with the fiscal year ended December 31, 2014, an Officers’ Certificate stating that a review of the activities of the Issuer and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether each has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that, to his or her knowledge, each entity has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuer is taking or proposes to take with respect thereto) and that, to his or her knowledge, no event has occurred and remains in existence by reason of which payments on account of the principal of, premium, if any, or interest on the Notes is prohibited or if such event has occurred, a description of the event and what action the Issuer is taking or proposes to take with respect thereto.

The Issuer shall, so long as any of the Notes are outstanding, deliver to the Trustee, within 30 days after any Officer becomes aware of any Default, an Officers’ Certificate specifying such Default and what action the Issuer is taking or proposes to take with respect thereto.

SECTION 4.5. Taxes . The Issuer shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency all material taxes, assessments and governmental levies, except such as are contested in good faith and by appropriate proceedings and with respect to which appropriate reserves have been taken in accordance with GAAP or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

SECTION 4.6. Stay, Extension and Usury Laws . The Issuer and each of the Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture, and the Issuer and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

SECTION 4.7. Limitation on Restricted Payments .

(2) the Issuer is not able to incur at least $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception; or

(3) the amount of such Restricted Payment, when added to the aggregate amount of all other Restricted Payments made after the Issue Date (other than Restricted Payments made pursuant to clauses (2) through (11) of Section 4.7(b), exceeds the sum (the “ Restricted Payments Basket ”) of (without duplication):

(A) 50.0% of Consolidated Net Income of the Issuer and the Restricted Subsidiaries for the period (taken as one accounting period) commencing on April 1, 2014 to and including the last day of the fiscal quarter ended immediately prior to the date of such calculation for which consolidated financial statements are available (or, if such Consolidated Net Income shall be a deficit, minus 100.0% of such deficit),

55

(E) upon a Redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, an amount (to the extent not included in the computation of Consolidated Net Income) equal to the lesser of (i) the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary immediately following such Redesignation, and (ii) the aggregate amount of the Issuer’s Investments in such Subsidiary to the extent such Investments reduced the Restricted Payments Basket and were not previously repaid or otherwise reduced,

provided that, notwithstanding the foregoing, there shall be no increase to the Restricted Payments Basket in respect of the issuance of the Tangible Equity Units or any Qualified Equity Interests purchased (or to be purchased) pursuant to the Tangible Equity Units or the component parts thereof.

provided that no issuance and sale of Qualified Equity Interests used to make a payment pursuant to clauses (2) or (5)(B) above shall increase the Restricted Payments Basket to the extent of such payment.

For the avoidance of doubt, payments by the Issuer on, or with respect to, the Unsecured Notes, including any payments of interest, amortization payments and early payments of principal, shall not constitute Restricted Payments.

For the purposes of determining compliance with any U.S. dollar denominated restriction on Restricted Payments denominated in a foreign currency, the U.S. dollar equivalent amount of such Restricted Payment shall be calculated based on the relevant currency exchange rate in effect on the date that such Restricted Payment was made.

The Issuer will not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to Section 4.18. For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by the Issuer and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be deemed to be Restricted Payments or Permitted Investments, as determined by the Issuer, in an amount determined as set forth in the definition of “Investment.” Such designation will be permitted only if a Restricted Payment and Permitted Investments, as applicable, in such amount would be permitted at such time and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

(b) make loans or advances, or pay any Indebtedness or other obligation owed, to the Issuer or any other Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Issuer or any Restricted Subsidiary to other Indebtedness or obligations incurred by the Issuer or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or

58

(c) transfer any of its property or assets to the Issuer or any other Restricted Subsidiary (it being understood that such transfers shall not include any type of transfer described in clause (a) or (b) above);

(6) encumbrances or restrictions existing under or by reason of applicable law, regulation, order, approval, license or similar restriction;

(12) customary provisions in partnership agreements, limited liability company organizational governance documents, joint venture agreements, shareholder agreements and other similar agreements that in each case restrict the disposition or distribution of ownership interests in or assets of the partnership, limited liability company, joint venture, corporation or similar Person governed thereby;

63

Notwithstanding anything to the contrary, a Restricted Subsidiary that is not a Guarantor may not (and the Issuer will not permit any Restricted Subsidiary that is not a Guarantor to) incur any Indebtedness pursuant to the Coverage Ratio Exception or clause (1), (13), (15) or (18) of this Section 4.9(b) if after giving effect to such incurrence on a pro forma basis (including giving pro forma effect to the application of the proceeds thereof), more than an aggregate of $175.0 million of Indebtedness of Restricted Subsidiaries that are not Guarantors would be outstanding pursuant to the Coverage Ratio Exception and clauses (1), (13), (15) and (18) of this Section 4.9(b) (this paragraph is referred to as the “ Non-Guarantor Debt Cap ”).

Neither the Issuer nor any Guarantor will incur any Indebtedness that pursuant to its terms is subordinate or junior in right of payment to any other Indebtedness of the Issuer or such Guarantor, as applicable, unless such Indebtedness is subordinated in right of payment to the Notes and the Guarantees of the Notes to the same extent; provided that Indebtedness will not be considered subordinate or junior in right of payment to any other Indebtedness solely by virtue of being unsecured or secured to a greater or lesser extent or with greater or lower priority or by virtue of structural subordination or with different collateral or as a result of provisions that apply proceeds or amounts received by the borrower, obligor or issuer following a default or exercise of remedies in a certain order of priority.

For purposes of determining compliance with this Section 4.9, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (18) above or is entitled to be incurred pursuant to the Coverage Ratio Exception, the Issuer shall, in its sole discretion, classify such item of Indebtedness and may divide and classify such Indebtedness in more than one of the types of Indebtedness described (except that Indebtedness incurred (or outstanding) under the Credit Agreement on the Issue Date shall be deemed to have been incurred under clause (1) above), and may later reclassify any item of Indebtedness described in clauses (1) through (18) above ( provided that at the time of reclassification it meets the criteria in such category or categories). In addition, for purposes of determining any particular amount of Indebtedness under this Section 4.9, (i) guarantees or letter of credit obligations supporting Indebtedness otherwise included in the determination of such particular amount shall not be included so long as incurred by a Person that could have incurred such Indebtedness; and (ii) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

For the purposes of determining compliance with any U.S. dollar denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the U.S. dollar equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the earlier of the date that such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction

64

shall be deemed not to have been exceeded so long as the principal amount of such Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

Notwithstanding any other provision of this Section 4.9, in no event shall the reclassification of any lease or other liability as indebtedness due to a change in accounting principles after the Issue Date be deemed to be an incurrence of Indebtedness.

If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary then outstanding shall be deemed to be incurred by a Restricted Subsidiary as of such time (and, if such Indebtedness is not permitted to be incurred as of such time under this Section 4.9, the Issuer shall be in Default of this Section 4.9).

SECTION 4.10. Limitations on Asset Sales .

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless:

(1) the Issuer or such Restricted Subsidiary, as the case may be, receives consideration at least equal to the Fair Market Value (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Sale or, in circumstances where the Issuer or such Restricted Subsidiary grants a third party the right to purchase an asset, the date of such grant) of the shares and assets subject to such Asset Sale; and

(2) at least 75.0% of the total consideration from such Asset Sale and all other Asset Sales on a cumulative basis since the Issue Date received by the Issuer or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents.

For purposes of clause (2) above and for no other purpose, the following shall be deemed to be cash:

(A) the amount (without duplication) of any Indebtedness (other than Subordinated Indebtedness or intercompany Indebtedness) of the Issuer or such Restricted Subsidiary that is expressly assumed by the transferee of any such assets pursuant to a written agreement that releases the Issuer or such Restricted Subsidiary from further liability therefor,

(B) the amount of any securities, notes or other obligations received from such transferee that are within 180 days after such Asset Sale converted by the Issuer or such Restricted Subsidiary into cash (to the extent of the cash actually so received),

(C) any Designated Non-cash Consideration received by the Issuer or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration

65

received pursuant to this Section 4.10(a)(2)(C) that is at that time outstanding, not to exceed the greater of (i) $75.0 million and (ii) 2.5% of the Issuer’s Consolidated Tangible Assets at the time of receipt of such Designated Non-cash Consideration, with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value, provided that if the applicable Asset Sale is a Collateral Disposition, (x) any assets received pursuant to this clause (C) must become Collateral in which the Collateral Agent has a Second Priority Lien concurrently with such receipt, which Second Priority Lien shall be perfected to the extent required by the Indenture Documents, and

(D) the Fair Market Value of (i) any assets (other than securities) received by the Issuer or any Restricted Subsidiary to be used by it in a Permitted Business, (ii) Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary concurrently with the acquisition of such Person by the Issuer or (iii) a combination of (i) and (ii); provided that if the applicable Asset Sale is a Collateral Disposition, (x) any assets received pursuant to clause (i) of this clause (D) must become Collateral in which the Collateral Agent has a Second Priority Lien concurrently with such receipt, (y) any Equity Interests received pursuant to clause (ii) of this clause (D) must become Collateral in which the Collateral Agent has a Second Priority Lien concurrently with such receipt, which Second Priority Lien in the case of clauses (x) and (y) shall be perfected to the extent required by the Indenture Documents, and (z) to the extent any Person acquired pursuant to clause (ii) of this clause (D) becomes a wholly owned Restricted Subsidiary, such Person shall become a Guarantor.

If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be applied in accordance with this Section 4.10.

Any Asset Sale pursuant to an Event of Loss shall not be required to satisfy the conditions set forth in clauses (1) and (2) of this Section 4.10(a).

Notwithstanding the foregoing, the 75.0% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provisions on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75.0% limitation.

(b) If the Issuer or any Restricted Subsidiary engages in an Asset Sale, the Issuer or such Restricted Subsidiary may, no later than 365 days following the consummation thereof, apply all or any of the Net Available Proceeds therefrom to:

66

(1) (A) if the Asset Sale is a Collateral Disposition, repay, redeem, cash collateralize or otherwise retire any Indebtedness that constitutes First Priority Claims or Notes Obligations or (B) if the Asset Sale is not a Collateral Disposition, repay, redeem or otherwise retire any Indebtedness of the Issuer or a Restricted Subsidiary (other than any Disqualified Equity Interests or Subordinated Indebtedness of the Issuer or a Guarantor, and other than Indebtedness owed to the Issuer or an Affiliate of the Issuer); provided that, for purposes of clauses (A) and (B), any repayment, redemption or retirement of Indebtedness under or in respect of a revolving Credit Facility shall be accompanied by a permanent termination of the corresponding amount of commitments thereunder; or

(2) (A) if the Asset Sale is a Collateral Disposition (i) make any capital expenditure with respect to Collateral or otherwise invest all or any part of the Net Available Proceeds thereof in the purchase of assets (other than securities and excluding working capital or current assets for the avoidance of doubt) to be used by the Issuer or any Guarantor in a Permitted Business and that constitute Collateral, (ii) acquire Qualified Equity Interests held by a Person other than the Issuer or any of its Restricted Subsidiaries in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business, which Qualified Equity Interests shall be pledged as Collateral to the Collateral Agent upon such consummation (and if such acquired Person becomes a wholly owned Restricted Subsidiary, such acquired Person shall become a Guarantor) or (iii) a combination of (i) and (ii) or (B) if the Asset Sale is not a Collateral Disposition, (i) make any capital expenditure or otherwise invest all or any part of the Net Available Proceeds thereof in the purchase of assets (other than securities and excluding working capital or current assets for the avoidance of doubt) to be used by the Issuer or any Restricted Subsidiary in a Permitted Business, (ii) acquire Qualified Equity Interests held by a Person other than the Issuer or any of its Restricted Subsidiaries in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary concurrently with the consummation of such acquisition or (iii) a combination of (i) and (ii).

The amount of Net Available Proceeds not applied or invested as provided in clauses (1) or (2) of this Section 4.10(b) shall constitute “ Excess Proceeds .”

(c) On the 366th day after an Asset Sale (or, at the Issuer’s option, an earlier date), if the aggregate amount of Excess Proceeds equals or exceeds $25.0 million, the Issuer shall be required to make an offer to purchase or redeem (a “ Net Proceeds Offer ”) from all Holders the maximum principal amount of Notes to which the Net Proceeds Offer applies that may be purchased or redeemed out of the Excess Proceeds, at an offer price in cash in an amount equal to 100.0% of the principal amount of Notes plus accrued and unpaid interest thereon to (but excluding) the date of purchase, in accordance with the procedures set forth in this Indenture in denominations of $2,000 or integral multiples of $1,000 in excess thereof.

To the extent that the sum of the aggregate principal amount of Notes so validly tendered pursuant to a Net Proceeds Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds, or a portion thereof, for any purposes not otherwise prohibited by the provisions of this Indenture. If the aggregate principal amount of Notes so validly tendered

67

pursuant to a Net Proceeds Offer exceeds the amount of Excess Proceeds, the Issuer shall select the Notes to be purchased on a pro rata basis on the basis of the aggregate outstanding principal amount of Notes. Upon completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero.

(d) The Net Proceeds Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “ Net Proceeds Offer Period ”). No later than five Business Days after the termination of the Net Proceeds Offer Period (the “ Net Proceeds Purchase Date ”), the Issuer will purchase the principal amount of Notes required to be purchased pursuant to this Section 4.10 (the “ Net Proceeds Offer Amount ”) or, if less than the Net Proceeds Offer Amount has been so validly tendered, all Notes validly tendered in response to the Net Proceeds Offer.

If the Net Proceeds Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Net Proceeds Offer.

Pending the final application of any Net Available Proceeds pursuant to this Section 4.10, the Issuer or the Restricted Subsidiary, as applicable, may apply such Net Available Proceeds temporarily to reduce Indebtedness outstanding under a revolving Credit Facility or otherwise invest such Net Available Proceeds in any manner not prohibited by this Indenture.

On or before the Net Proceeds Purchase Date, the Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Net Proceeds Offer Amount of Notes or portions of Notes so validly tendered and not properly withdrawn pursuant to the Net Proceeds Offer, or if less than the Net Proceeds Offer Amount has been validly tendered and not properly withdrawn, all Notes so validly tendered and not properly withdrawn, in each case in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Issuer or the Paying Agent, as the case may be, will promptly (but in any case not later than five Business Days after termination of the Net Proceeds Offer Period) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Issuer for purchase, and the Issuer will promptly issue a new Note, and the Trustee, upon delivery of an Officers’ Certificate from the Issuer, will authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Any Note not so accepted will be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer will publicly announce the results of the Net Proceeds Offer on the Net Proceeds Purchase Date.

Notwithstanding the foregoing, the sale, conveyance or other disposition of all or substantially all of the assets of the Issuer and its Restricted Subsidiaries, taken as a whole, will be governed by Section 4.14 and/or Section 5.1 and not by this Section 4.10.

68

The Issuer shall comply with all applicable securities laws and regulations in the United States, including, without limitation, the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 4.10, the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance.

SECTION 4.11. Limitation on Transactions with Affiliates .

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, in one transaction or a series of related transactions, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (an “ Affiliate Transaction ”), unless:

(1) the terms of such Affiliate Transaction are not materially less favorable to the Issuer or such Restricted Subsidiary, as the case may be, than those that could reasonably be expected to have been obtained in a comparable transaction at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate or are otherwise fair to the Issuer or such Restricted Subsidiary from a financial point of view; and

(2) the Issuer delivers to the Trustee, with respect to any Affiliate Transaction involving aggregate value in excess of $25.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and, with respect to any Affiliate Transaction involving aggregate value in excess of $40.0 million, a Secretary’s Certificate which sets forth and authenticates a resolution that has been adopted by a majority of the Independent Directors approving such Affiliate Transaction.

(b) The foregoing restrictions shall not apply to:

(1) transactions to the extent between or among (a) the Issuer and one or more Restricted Subsidiaries or (b) Restricted Subsidiaries;

(2) director, officer, employee and consultant compensation (including bonuses) and other benefits (including pursuant to any employment agreement or arrangement, severance agreement, consulting agreement or any retirement, health, stock option, other equity award or other benefit plan), payments or loans (or cancellation of loans) to employees of the Issuer and indemnification arrangements, including reimbursement or advance of out-of-pocket expenses and provision of officers’ and directors’ liability insurance;

(3) the entering into of a tax sharing agreement, or payments pursuant thereto, between the Issuer and/or one or more Subsidiaries, on the one hand, and any other Person with which the Issuer or such Subsidiaries are required or permitted to file a consolidated tax return or with which the Issuer or such Subsidiaries are part of a consolidated group for tax purposes to be used by such Person to pay taxes, and which payments by the Issuer and the Restricted Subsidiaries, collectively, are not in excess of the tax liabilities that would have been payable by them, collectively, on a stand-alone basis;

69

(4) any Permitted Investments (other than pursuant to clause (1) of the definition thereof);

(5) any Restricted Payments which are made in accordance with Section 4.7;

(6) any agreement, arrangement or commitment in effect on the Issue Date or as thereafter amended or replaced in any manner that, taken as a whole, is not more disadvantageous to the Issuer in any material respect than such agreement as it was in effect on the Issue Date;

(7) any transaction with a Person (other than an Unrestricted Subsidiary) which would constitute an Affiliate of the Issuer solely because the Issuer or a Restricted Subsidiary owns an equity interest in or otherwise controls such Person;

(8) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the applicable terms of this Indenture; provided that in the reasonable determination of the Board of Directors of the Issuer or the senior management of the Issuer, such transactions are on terms not materially less favorable to the Issuer or the relevant Restricted Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Issuer;

(9) (a) any transaction with an Affiliate where the only consideration paid by the Issuer or any Restricted Subsidiary is Qualified Equity Interests and (b) the issuance or sale of any Qualified Equity Interests and the granting of registration and other customary rights in connection therewith;

(10) pledges by the Issuer or any Restricted Subsidiary of Equity Interests in Unrestricted Subsidiaries for the benefit of lenders or other creditors of the Unrestricted Subsidiaries;

(11) transactions entered into by a Person prior to the time such Person becomes a Subsidiary or is merged or consolidated into the Issuer or a Restricted Subsidiary ( provided that such transaction is not entered into in contemplation of such event);

(12) dividends and distributions to the Issuer or a Restricted Subsidiary by any Unrestricted Subsidiary or Permitted Joint Venture; and

(13) transactions entered into as part of a Receivables Program.

70

SECTION 4.12. Limitations on Liens . The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or permit or suffer to exist any Lien (other than Permitted Liens) upon any of their property or assets (including Equity Interests of any Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, which Lien secures Indebtedness.

SECTION 4.13. Payments for Consent . The Issuer will not, and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that so consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

SECTION 4.14. Offer to Purchase upon Change of Control . Upon the occurrence of any Change of Control, unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes as described under Section 3.7, each Holder will have the right to require that the Issuer purchase all or any portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes for a cash price (the “ Change of Control Purchase Price ”) equal to 101.0% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon to (but excluding) the date of purchase.

Not later than 30 days following any Change of Control, the Issuer will deliver, or cause to be delivered, to the Holders, with a copy to the Trustee, a notice:

(1) describing the transaction or transactions that constitute the Change of Control;

(2) offering to purchase, pursuant to the procedures required by this Indenture and described in the notice (a “ Change of Control Offer ”), on a date specified in the notice, which shall be a Business Day not earlier than 30 days, nor later than 60 days, from the date the notice is delivered (the “ Change of Control Payment Date ”), and for the Change of Control Purchase Price, all Notes properly tendered by such Holder pursuant to such Change of Control Offer prior to 5:00 p.m. New York time on the second Business Day preceding the Change of Control Payment Date; and

(3) describing the procedures, as determined by the Issuer, consistent with this Indenture, that Holders must follow to accept the Change of Control Offer.

On or before the Change of Control Payment Date, the Issuer will, to the extent lawful, deposit with the Paying Agent an amount equal to the Change of Control Purchase Price in respect of the Notes or portions of Notes properly tendered.

On the Change of Control Payment Date, the Issuer will, to the extent lawful:

(1) accept for payment all Notes or portions of Notes (of $2,000 or integral multiples of $1,000 in excess thereof) properly tendered pursuant to the Change of Control Offer; and

71

(2) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

The Paying Agent will promptly deliver to each Holder who has so tendered Notes the Change of Control Purchase Price for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes so tendered, if any; provided that each such new Note will be in a principal amount of $2,000 or integral multiples of $1,000 in excess thereof.

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest will be paid on the relevant interest payment date to the Person in whose name a Note is registered at the close of business on such record date.

A Change of Control Offer shall remain open for at least 20 Business Days or for such longer period as is required by applicable law. The Issuer shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the date of purchase.

The Issuer’s obligation to make a Change of Control Offer shall be satisfied if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer.

If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Issuer, or any third party making a Change of Control Offer in lieu of the Issuer as described above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuer will have the right, upon not less than 30 days’ nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Purchase Price plus, to the extent not included in the Change of Control Purchase Price, accrued and unpaid interest to (but excluding) the date of redemption.

The Issuer shall comply with all applicable securities legislation in the United States, including, without limitation, the requirements of Rule 14e-l under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 4.14, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.14 by virtue of such compliance.

The provisions under this Indenture relating to the Issuer’s obligation to make a Change of Control Offer may be waived, modified or terminated with the written consent of the Holders of a majority in principal amount of the Notes then outstanding.

72

Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

SECTION 4.15. Corporate Existence . Subject to Section 4.14 and Article V, as the case may be, the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership, limited liability company or other existence of each of its Restricted Subsidiaries in accordance with the respective organizational documents (as the same may be amended from time to time) of the Issuer or any such Restricted Subsidiary and the rights (charter and statutory), licenses and franchises of the Issuer and its Restricted Subsidiaries; provided that the Issuer shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors of the Issuer shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders.

SECTION 4.16. Business Activities . The Issuer shall engage, and shall cause its Restricted Subsidiaries to engage, in businesses that, when considered together as a single enterprise, are primarily the Permitted Business.

SECTION 4.17. Additional Guarantees . If any Restricted Subsidiary, other than a Guarantor, shall guarantee any Indebtedness of the Issuer or any Guarantor under a Credit Facility, then the Issuer shall, within 30 days thereof, cause such Restricted Subsidiary to execute and deliver to the Trustee a supplemental indenture in substantially the form attached hereto as Exhibit B , pursuant to which such Restricted Subsidiary shall become a Guarantor with respect to the Notes, upon the terms and subject to the release provisions and other limitations described under Section 10.1.

SECTION 4.18. Limitations on Designation of Unrestricted Subsidiaries . The Board of Directors of the Issuer may designate any Subsidiary (including any newly formed or newly acquired Subsidiary or a Person becoming a Subsidiary through merger or consolidation or Investment therein) of the Issuer as an “Unrestricted Subsidiary” under this Indenture (a “ Designation ”) only if:

(1) no Default shall have occurred and be continuing at the time of or after giving effect to such Designation; and

(2) the Issuer would be permitted to make, at the time of such Designation, (a) a Permitted Investment or (b) an Investment pursuant to Section 4.7, in either case, in an amount (the “ Designation Amount ”) equal to the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary on such date.

No Subsidiary shall be Designated as an “Unrestricted Subsidiary” unless:

73

(1) all of the Indebtedness of such Subsidiary and its Subsidiaries shall, at the date of Designation, consist of Non-Recourse Debt, except for any guarantee given solely to support the pledge by the Issuer or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not recourse to the Issuer or any Restricted Subsidiary, and except for any guarantee of Indebtedness of such Subsidiary by the Issuer or a Restricted Subsidiary that is permitted as both an incurrence of Indebtedness and an Investment (in each case in an amount equal to the amount of such Indebtedness so guaranteed) permitted by Sections 4.7 and 4.9;

(2) on the date such Subsidiary is Designated an Unrestricted Subsidiary, such Subsidiary is not party to any agreement, contract, arrangement or understanding (other than a guarantee permitted under clause (1) above) with the Issuer or any Restricted Subsidiary unless the terms of the agreement, contract, arrangement or understanding are not materially less favorable to the Issuer or the Restricted Subsidiary than those that could reasonably be expected to have been obtained at the time from Persons who are not Affiliates of the Issuer, as determined in good faith by the Issuer; and

(3) such Subsidiary is a Person with respect to which neither the Issuer nor any of its Restricted Subsidiaries has any direct or indirect obligation (a) to subscribe for additional Equity Interests of such Person or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any specified levels of operating results (in each case other than a guarantee permitted under clause (1) above).

Any such Designation by the Board of Directors of the Issuer shall be evidenced to the Trustee by filing with the Trustee a resolution of the Board of Directors of the Issuer giving effect to such Designation and an Officers’ Certificate certifying that such Designation complies with the foregoing conditions. If, at any time, any Unrestricted Subsidiary fails to meet the preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary at such time and, if the Indebtedness is not permitted to be incurred under Section 4.9 or the Lien is not permitted under Section 4.12, the Issuer shall be in default of the applicable covenant. Notwithstanding anything to the contrary, no Guarantor may be designated as an Unrestricted Subsidiary if it provides (or continues to provide) a guarantee of any Credit Facility unless such Guarantor is substantially concurrently being designated as an “unrestricted subsidiary” under such Credit Facility.

The Board of Directors of the Issuer may redesignate an Unrestricted Subsidiary as a Restricted Subsidiary (a “ Redesignation ”) only if:

(1) no Default shall have occurred and be continuing at the time of and after giving effect to such Redesignation; and

(2) all Liens, Indebtedness and Investments of such Unrestricted Subsidiary outstanding immediately following such Redesignation would, if incurred or made at such time, have been permitted to be incurred or made for all purposes of this Indenture.

74

Any such Redesignation shall be evidenced to the Trustee by filing with the Trustee a resolution of the Board of Directors of the Issuer giving effect to such designation and an Officers’ Certificate certifying that such Redesignation complies with the foregoing conditions.

SECTION 4.19. Further Assurances . (a) The Issuer and the Guarantors shall, at their expense and to the extent not in violation of the Intercreditor Agreement, duly execute and deliver, or cause to be duly executed and delivered, such further agreements, documents and instruments, and do or cause to be done such further acts (i) as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture or (ii) as the Collateral Agent may reasonably request to grant, evidence, perfect, maintain and enforce the security interests and the priority thereof in the Collateral in favor of the Collateral Agent for its benefit and for the benefit of the Holders and any other Secured Parties and the Trustee, and to otherwise effectuate the provisions or purposes of this Indenture and the Collateral Agreements.

(b) The Issuer and the Guarantors will (i) maintain insurance with responsible and reputable insurance companies or associations in such amounts and covering such risks as, in the reasonable determination of the Issuer, is usually carried out by companies engaged in similar businesses and owning similar properties in the same general areas in which the Issuer or such Subsidiary operates; provided that, with respect to the Mortgaged Vessels, the Issuer shall be required to provide or cause to be provided only such insurance as is required by the Collateral Agreements, and (ii) cause all property and general liability insurance policies to name the Collateral Agent on behalf of the Secured Parties as additional insured (with respect to liability and property policies), loss payee (with respect to property policies) or lender’s loss payee (with respect to property policies), as appropriate, and to provide that no cancellation, material addition in amount or material change in coverage shall be effective until after 30 days’ written notice to the Collateral Agent. So long as an Event of Default is not then continuing, the Collateral Agent, on behalf of the Secured Parties, agrees to promptly release, endorse and turn over to the Issuer or the applicable Subsidiary any insurance proceeds received by the Collateral Agent.

SECTION 4.20. After-Acquired Collateral; Additional Security Interests . From and after the Issue Date, if and to the extent that the Issuer or any Guarantor executes and delivers any First Priority Security Documents (including any amendments, supplements or modifications to any First Priority Security Documents) or takes any other actions (including any actions taken in the United States of America or in any other jurisdiction) to grant a perfected security interest in any property or asset (including a marine vessel) to secure the First Priority Claims (including in connection with any acquisition by the Issuer or any Guarantor of any property or asset after the Issue Date), the Issuer shall, and shall cause such Guarantor to, promptly (but in any event not later than the date that is 10 Business Days after the date on which such First Priority Security Documents are executed and delivered or such other actions are taken with respect to the First Priority Liens), to the extent a Second Priority Lien may be granted or perfected in such property or asset, (a) execute and deliver to the Collateral Agent such Collateral Agreements (including any amendments and supplements thereto) and take such other actions to grant the Collateral Agent a perfected Second Priority Lien in such Collateral to secure the Notes Obligations (in each case, to the same extent as any First Priority Security Documents were executed and delivered and any other actions were taken in connection with granting a perfected security interest in such property or asset to secure the First Priority Claims) and (b) cause to be delivered to the Collateral Agent legal opinions and other deliverables related thereto (in each

75

case, to the extent such legal opinions and other deliverables were delivered to the First Priority Agent in connection with granting a perfected security interest in such property or asset to secure the First Priority Claims). The Issuer will not, and will not permit its Subsidiaries to, take any action, or knowingly omit to take any action, which action or omission would have the result of materially impairing the validity, perfection or priority of the security interests in the Collateral created by the Collateral Agreements (except as permitted in this Indenture, the Intercreditor Agreement or the other Collateral Agreements). Notwithstanding anything to the contrary contained herein, to the extent that any Lien on any Collateral is perfected by the First Priority Agent (or any of its agents or bailees) by obtaining “control” (as defined in the UCC) of such Collateral, the obligation of the Issuer and the Guarantors to grant the Collateral Agent, or to cause the Collateral Agent to obtain, such “control” of such Collateral shall be limited to using their commercially reasonable efforts to grant the Collateral Agent, or to cause the Collateral Agent to obtain, such “control” of such Collateral.

SECTION 4.21. Covenant Suspension .

(a) If on any date following the Issue Date (i) the Notes have an Investment Grade Rating from both Rating Agencies and (ii) no Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “ Covenant Suspension Event ”), the Issuer and the Restricted Subsidiaries will not be subject to the following covenants (collectively, the “ Suspended Covenants ”):

(1) Section 4.7;

(2) Section 4.8;

(3) Section 4.9;

(4) Section 4.10;

(5) Section 4.11;

(6) Section 4.16; and

(7) Section 5.1(a)(3).

(b) In the event that the Issuer and its Restricted Subsidiaries are not subject to the Suspended Covenants under this Indenture for any period of time as a result of the foregoing, and on any subsequent date (the “ Reversion Date ”) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade Rating, then the Issuer and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events.

(c) The Issuer shall promptly notify the Trustee of the existence, and of the termination of any Covenant Suspension Event or Reversion Date by filing with the Trustee an Officers’ Certificate certifying the same; provided , however , that the Trustee shall have no obligation to discover or verify the existence or termination of any Covenant Suspension Event or Reversion Date.

76

(d) The period of time between the occurrence of a Covenant Suspension Event and the Reversion Date is referred to herein as the “ Suspension Period .” Solely for the purpose of determining the amount of Permitted Liens in accordance with the provisions of Section 4.12 during any Suspension Period and without limiting the Issuer’s or any Restricted Subsidiary’s ability to incur Indebtedness without restriction during any Suspension Period, to the extent that calculations as set forth in the definition of “Permitted Liens” refer to the covenant set forth in Section 4.9, such calculations shall be made as though the covenant set forth in Section 4.9 remains in effect during the Suspension Period. Additionally, upon the occurrence of a Covenant Suspension Event, the amount of Excess Proceeds shall be reset at zero.

(e) In the event of any reinstatement of the Suspended Covenants, from and after the Reversion Date, no action taken or omitted to be taken by the Issuer or any of its Restricted Subsidiaries prior to such reinstatement will give rise to a Default under this Indenture with respect to Notes; provided , however , that with respect to Restricted Payments made after any such reinstatement, the amount of Restricted Payments made will be calculated as though the covenant as set forth in Section 4.7 had been in effect prior to, but not during, the Suspension Period. No Subsidiaries shall be designated as Unrestricted Subsidiaries during the Suspension Period. All Indebtedness incurred during the Suspension Period will be classified to have been incurred or issued pursuant to clause (3) of the definition of “Permitted Indebtedness” herein. Any Affiliate Transaction entered into after the Reversion Date pursuant to an agreement entered into during any Suspension Period shall be deemed to be permitted pursuant to clause (6) of Section 4.11(b).

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such use by a Holder prejudices the rights of any other Holders or obtains priority or preference over such other Holders).

SECTION 6.7. Rights of Holders to Receive Payment .

To the extent that the payment of any such compensation, expenses, disbursements and advances to the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.6 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in

84

such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

SECTION 6.11. Undertaking for Costs . In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, 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.

SECTION 7.2. Rights of Trustee .

(a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting on any resolution, certificate, statement, instrument, opinion, notice, report, request, direction, consent, order, bond, debenture or other document (whether in original or facsimile form) believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated therein.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. Prior to taking, suffering or admitting any action, the Trustee may consult with counsel of the Trustee’s own choosing, and the Trustee shall be fully protected from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in conclusive reliance on the advice or opinion of such counsel.

(c) The Trustee may act through its attorneys, attorneys-in-fact and agents and shall not be responsible for the misconduct or negligence of any attorney or agent appointed with due care.

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

(g) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or documents, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine during normal business hours the books, records and premises of the Issuer, personally or by agent or attorney at the sole cost of the Issuer, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, the Collateral Agent, the Agents and each other agent, attorney, attorney-in-fact, custodian and Person employed to act hereunder.

87

(i) The Trustee may request that the Issuer and each of the Guarantors shall deliver to the Trustee an Officers’ Certificate setting forth the names of individuals and/or titles of Officers of the Issuer and each Guarantor, as applicable, authorized at such time to take specified actions pursuant to this Indenture, the Notes and the Guarantees, which Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded.

(j) The Trustee shall not be deemed to have notice or be charged with knowledge of any Default unless a Responsible Officer of the Trustee has actual knowledge thereof or the Trustee shall have received from the Issuer or any other obligor upon the Notes or from any Holder written notice thereof at its address set forth in Section 12.1 and such notice references the Notes and this Indenture. In the absence of such actual knowledge or such notice, the Trustee may conclusively assume that no such Default exists.

(k) In no event shall the Trustee be responsible or liable for special, indirect, punitive, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(l) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

SECTION 7.3. Individual Rights of the Trustee . The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest, it must eliminate such conflict within ninety (90) days, apply to the SEC for permission to continue as Trustee (if this Indenture has been qualified under the Trust Indenture Act of 1939, as amended) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.9 hereof.

SECTION 7.4. Trustee’s Disclaimer . The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or any Guarantee, it shall not be accountable for the use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes, any Officers’ Certificate delivered to the Trustee hereunder, or any other document in connection with the sale of the Notes or pursuant to this Indenture other than the Trustee’s certificate of authentication hereunder.

SECTION 7.5. Notice of Defaults . If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall deliver to Holders a notice of the Default within 60 days after it occurs. Except in the case of a Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determines that withholding the notice is in the interests of the Holders.

88

SECTION 7.6. Compensation and Indemnity . The Issuer shall pay to the Trustee from time to time compensation for its acceptance of this Indenture and for all services rendered by it hereunder as agreed upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services, except any such disbursements, expenses and advances as may be attributable to the Trustee’s gross negligence, bad faith or willful misconduct. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

Each of the Issuer and the Guarantors, jointly and severally, shall indemnify the Trustee (which for purposes of this Section 7.6 shall include its officers, directors, employees and agents) against any and all claims, damages, losses, liabilities, costs or expenses incurred by it (including, without limitation, the fees and expenses of its agents and counsel) arising out of or in connection with the acceptance or administration of its duties under this Indenture, the performance of its obligations and/or exercise of its rights hereunder, including the costs and expenses of enforcing this Indenture against the Issuer or any Guarantor (including this Section 7.6) and defending itself against any claim (whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, claim, damage, liability or expense shall be caused by its own gross negligence, bad faith or willful misconduct. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Trustee may have one separate counsel in each relevant jurisdiction, and the Issuer shall pay the reasonable fees and expenses of such counsel for the Trustee. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

The obligations of the Issuer and the Guarantors under this Section 7.6 shall survive the discharge of this Indenture, the payment of the Notes or the resignation or removal of the Trustee.

To secure the Issuer’s payment obligations in this Section 7.6, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal or interest, if any, on particular Notes. Such Lien shall survive the discharge of this Indenture, the payment of the Notes and the resignation or removal of the Trustee.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(7) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

SECTION 7.7. Replacement of Trustee . A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor trustee’s acceptance of appointment as provided in this Section 7.7.

89

The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing. The Issuer may remove the Trustee if:

(a) the Trustee fails to comply with Section 7.9 hereof;

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to such Trustee under any Bankruptcy Law;

(c) a custodian or public officer takes charge of the Trustee or its property; or

(d) the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason, the Issuer shall promptly appoint a successor trustee. Within one year after the successor trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor trustee to replace the successor trustee appointed by the Issuer.

If a successor trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor trustee.

If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.9 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee.

A successor trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor trustee shall have all the rights, powers and the duties of the Trustee under this Indenture. The successor trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided that all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.6. Notwithstanding replacement of the Trustee pursuant to this Section 7.7, the Issuer’s and the Guarantors’ obligations under Section 7.6 shall continue for the benefit of the retiring Trustee.

SECTION 7.8. Successor Trustee by Merger, Etc . If the Trustee or any Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business (including this transaction) to, another corporation, the successor corporation without any further act shall be the successor Trustee or Agent, as applicable.

SECTION 7.9. Eligibility; Disqualification . There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state authorities. Such Trustee together with its affiliates shall at all times have a combined capital surplus of at least $50.0 million as set forth in its most recent annual report of condition.

For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer or any of its Subsidiaries may omit to comply with and shall have no liability in respect of any term,

91

condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.1, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby.

(1) the Issuer must irrevocably deposit with the Trustee, as trust funds, in trust solely for the benefit of the Holders, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Issuer which is delivered to the Trustee, to pay the principal of and interest on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be,

(2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that:

(A) the Issuer has received from, or there has been published by the United States Internal Revenue Service, a ruling, or

(B) since the Issue Date, there has been a change in the applicable U.S. federal income tax law,

in either case to the effect that, and based thereon, such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred,

92

(3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the Covenant Defeasance had not occurred,

(4) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to make the deposit required to effect such Legal Defeasance or Covenant Defeasance and the granting of any Lien securing such borrowings),

(5) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound (other than this Indenture),

(6) the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by it with the intent of preferring the Holders over any other of its creditors or with the intent of defeating, hindering, delaying or defrauding any other of its creditors or others, and

(7) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each to the effect that the conditions precedent provided for in clauses (1) through (6) have been complied with.

SECTION 8.5. Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous Provisions . Subject to Section 8.6, all U.S. legal tender and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively, for purposes of this Section 8.5, the “ Deposit Trustee ”) pursuant to Section 8.4 in respect of the outstanding Notes shall be held in trust, shall not be invested, and shall be applied by the Deposit Trustee in accordance with the provisions of such Notes and this Indenture to the payment, either directly or through any Paying Agent (including the Issuer or any Subsidiary acting as Paying Agent) as the Deposit Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuer shall pay and indemnify the Deposit Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to Section 8.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Anything in this Article VIII to the contrary notwithstanding, the Deposit Trustee shall deliver or pay to the Issuer from time to time upon the written request of the Issuer and be relieved of all liability with respect to any U.S. legal tender or non-callable U.S. Government Obligations held by it as provided in Section 8.4 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Deposit Trustee (which may be the opinion delivered under Section 8.4(1)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

93

If the funds deposited with the Deposit Trustee to effect Covenant Defeasance or Legal Defeasance are insufficient to pay the principal of and interest on the Notes when due, then the Issuer’s obligations and the obligations of the Guarantors under this Indenture will be revived and no such defeasance will be deemed to have occurred.

SECTION 8.6. Repayment to Issuer . Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal and premium, if any, or interest has become due and payable shall be paid to the Issuer on its written request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof; and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided , however , that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Issuer.

SECTION 8.7. Reinstatement . If the Trustee or Paying Agent is unable to apply any U.S. dollars or U.S. Government Obligations in accordance with Section 8.2, Section 8.3 or Section 8.8, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Issuer and the Guarantors under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2, Section 8.3 or Section 8.8 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2, Section 8.3 or Section 8.8, as the case may be; provided , however , that, if the Issuer makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

SECTION 8.8. Discharge . This Indenture shall be discharged and shall cease to be of further effect (except as to rights of registration of transfer or exchange of Notes which shall survive until all Notes have been canceled and the rights, protections and immunities of the Trustee) as to all outstanding Notes when either:

(a) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from this trust), have been delivered to the Trustee for cancellation; or

(b)

94

In addition, the Issuer must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to the discharge of this Indenture pursuant to this Section 8.8 have been complied with.

In the case of clause (b) of this Section 8.8, and subject to the next sentence and notwithstanding the foregoing paragraph, the Issuer’s and the Guarantors’ obligations, as applicable, in Section 2.2, Section 2.3, Section 2.4, Section 2.5, Section 2.6, Section 2.7, Section 2.10, Section 2.12, Section 2.15, Section 2.17, Section 4.1, Section 4.2, Section 4.15 (as to legal existence of the Issuer only), Section 7.6, Section 8.5 and Section 8.7 shall survive until the Notes are no longer outstanding pursuant to the last paragraph of Section 2.8. After the Notes are no longer outstanding, the Issuer’s and the Guarantors’ obligations in Section 7.6, Section 8.5 and Section 8.7 shall survive any discharge pursuant to this Section 8.8.

After such delivery or irrevocable deposit and receipt of the Officers’ Certificate and Opinion of Counsel, the Trustee, upon written request, shall acknowledge in writing the discharge of the Issuer’s obligations under the Notes and this Indenture except for those surviving obligations specified above.

In addition, the consent of Holders representing at least 66 2/3% of the outstanding Notes shall be required to release the Liens for the benefit of the Holders of the Notes on all or substantially all of the Collateral, other than any such release in accordance with this Indenture, the Intercreditor Agreement and the Collateral Agreements.

It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

SECTION 9.3. Revocation and Effect of Consents . Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. When an amendment, supplement or waiver becomes effective in accordance with its terms, it thereafter binds every Holder.

The Issuer may, but shall not be obligated to, fix a record date for determining which Holders consent to such amendment, supplement or waiver. If the Issuer fixes a record date, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation pursuant to Section 2.5 or (ii) such other date as the Issuer shall designate.

SECTION 9.4. Notation on or Exchange of Notes . The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.5. Trustee to Sign Amendments, Etc . The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In signing or refusing to sign any amendment or supplemental indenture, the Trustee shall be provided with and (subject to Section 7.1) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture, that all conditions precedent

thereto have been met or waived, that such amendment or supplemental indenture is not inconsistent herewith and that it will be valid and binding upon the Issuer and the Guarantors in accordance with its terms.

GUARANTEES

SECTION 10.1. Guarantees .

(a) Each Guarantor hereby jointly and severally, fully and unconditionally guarantees the Notes and obligations of the Issuer hereunder and thereunder, and guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee, that: (i) the principal of and premium, if any, and interest on the Notes shall be paid in full when due, whether at Stated Maturity, by acceleration, call for redemption or otherwise (including, without limitation, the amount that would become due but for the operation of the automatic stay under Section 362(a) of Title 11 of the U.S. Code), together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other Obligations of the Issuer to the Holders or the Trustee under this Indenture or the Notes shall be paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. Each of the Guarantees shall be a guarantee of payment and not of collection.

(b) Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

(c) Each Guarantor hereby waives the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer or any other Person, any right to request the division of the payment obligations among the Guarantors, any right to request that any Collateral be foreclosed upon, protest, notice and all demands whatsoever and covenants that the Guarantee of such Guarantor shall not be discharged as to any Note or this Indenture except by complete performance of the obligations contained in such Note and this Indenture and such Guarantee. Each of the Guarantors hereby agrees that, in the event of a Default in payment of principal or premium, if any, or interest on any Note, whether at its Stated Maturity, by acceleration, call for redemption, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce each such Guarantor’s Guarantee without first proceeding against the Issuer or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes, or to enforce or exercise any

99

other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders and any other amounts due and owing to the Trustee under this Indenture.

(d) If any Holder or the Trustee is required by any court or otherwise to return to the Issuer or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. This paragraph (d) shall remain effective notwithstanding any contrary action which may be taken by the Trustee or any Holder in reliance upon such amount required to be returned. This paragraph (d) shall survive the termination of this Indenture.

(e) Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of the Guarantee of such Guarantor, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VI, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Guarantee of such Guarantor.

(f) Each Guarantor acknowledges that each Guarantee will be a general obligation of such Guarantor and will rank senior in right of payment to all future Obligations of such Guarantor that are, by their terms, expressly subordinated in right of payment to such Guarantee and equal in right of payment with all existing and future obligations of such Guarantor that are not so subordinated.

(g) Each Guarantee will be secured by a second-priority Lien on the Collateral owned by such Guarantor, subject to the terms of the Intercreditor Agreement.

(h) Each Guarantor that makes a payment for distribution under its Guarantee is entitled upon payment in full of all guaranteed obligations under this Indenture to seek contribution from each other Guarantor in a pro rata amount of such payment based on the respective net assets of all the Guarantors at the time of such payment in accordance with GAAP or applicable law.

SECTION 10.2. Execution and Delivery of Guarantee . To evidence its Guarantee set forth in Section 10.1, each Guarantor agrees that this Indenture or a supplemental indenture in substantially the form attached hereto as Exhibit B shall be executed on behalf of such Guarantor by an Officer of such Guarantor (or, if an officer is not available, by a board member or director) on behalf of such Guarantor by manual or facsimile signature. Each Guarantor hereby agrees that its Guarantee set forth in Section 10.1 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. In case the Officer, board member or director of such Guarantor whose signature is on this Indenture or supplemental indenture, as applicable, no longer holds office at the time the Trustee authenticates any Note, the Guarantee shall be valid nevertheless.

100

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors.

If required by Section 4.17 hereof, the Issuer shall cause each Restricted Subsidiary described in Section 4.17 hereof to comply with the provisions of Section 4.17 hereof and this Article X, to the extent applicable.

SECTION 10.3. Severability . In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 10.4. Limitation of Guarantors’ Liability . (a) Each Guarantor and by its acceptance hereof each Holder confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor under its Guarantee (other than a company that is a direct or indirect parent of the Issuer) shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee, result in the obligations of such Guarantor under its Guarantee constituting a fraudulent conveyance, fraudulent preference, or fraudulent transfer or otherwise reviewable transaction under applicable law.

(b) Notwithstanding anything set out to the contrary in this Indenture or any other Indenture Document, the obligations and liabilities of J. Ray McDermott (Norway) AS under any provision of this Indenture or any other Indenture Document to which it is a party shall not include any obligations or liabilities to the extent they would constitute unlawful financial assistance within the meaning of Section 8-7 and/or 8-10, cfr. Section 1-4, of the Norwegian Companies Act of 13 June 1997 no. 44, and the obligations and liabilities of J. Ray McDermott (Norway) AS under this Indenture or any other Indenture Document only apply to the extent permitted by those provisions of the Norwegian Companies Act of 13 June 1997 no. 44.

(c) The total liability of J. Ray McDermott (Norway) AS under this Indenture or any other Indenture Document to which it is a party shall never exceed $1,000,000,000 plus interest thereon and fees, costs and expenses as set out in this Indenture or any other Indenture Document.

SECTION 10.5. Releases . A Guarantor shall be released and relieved of any Obligations under its Guarantee and this Indenture:

(a) upon any sale, exchange or transfer (by merger, consolidation or otherwise) of the Equity Interests of such Guarantor after which the applicable Guarantor is no longer a Restricted Subsidiary, which sale, exchange or transfer does not violate this Indenture;

101

(b) upon designation by the Board of Directors of the Issuer as an Unrestricted Subsidiary in accordance with the terms of this Indenture;

(c) in the case of any Restricted Subsidiary that after the Issue Date is required to guarantee the Notes pursuant to the requirements of Section 4.17, upon the release or discharge of such Restricted Subsidiary’s guarantee of Indebtedness of the Issuer or any Guarantor that resulted in the obligation of such Restricted Subsidiary to guarantee the Notes pursuant to such Section 4.17, except if any such release or discharge is by or as a result of payment under such other guarantee; provided that no continuing Event of Default relating to the failure to make required payments on the Notes exists;

(d) if the Issuer exercises its Legal Defeasance option or its Covenant Defeasance option pursuant to Section 8.2 or Section 8.3 or if this Indenture is discharged in accordance with Section 8.8;

(e) upon dissolution of such Guarantor, which dissolution does not violate the provisions of this Indenture;

(f) in accordance with the provisions of Article IX; or

(g) as otherwise provided in the Intercreditor Agreement, including, without limitation, with respect to any Guarantor that is released from its obligations to guarantee the First Priority Claims to the extent set forth in the Intercreditor Agreement.

Upon delivery to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that all conditions precedent to the release of a Guarantor’s Guarantee set forth in this Indenture have been satisfied, the Trustee shall execute any documents reasonably requested by the Issuer in writing in order to evidence the release of any Guarantor from its obligations under its Guarantee.

Any Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article X.

SECTION 10.6. Benefits Acknowledged . Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its guarantee and waivers pursuant to its Guarantee are knowingly made in contemplation of such benefits.

ARTICLE XI

COLLATERAL AND SECURITY

SECTION 11.1. Security Interest . The Notes Obligations are secured by Second Priority Liens on the Collateral as provided in the Collateral Agreements. Each Holder, by its acceptance of a Note, consents and agrees to the terms of the Collateral Agreements (including the provisions providing for foreclosure and release of Collateral by the Collateral Agent, relating to ranking of Second Priority Liens and order of application of proceeds from enforcement of Second Priority Liens) as the same may be in effect or may be amended,

102

amended and restated, modified, renewed, restated or replaced from time to time in accordance with their terms and each Holder and the Trustee hereby authorizes and appoints Wells Fargo Bank, National Association, as Collateral Agent, and each Holder and the Trustee direct the Collateral Agent to enter into the Collateral Agreements and to perform its obligations and exercise its rights thereunder in accordance therewith and to exercise such powers as are delegated to the Trustee and the Collateral Agent by the terms thereof, together with such actions and powers as are reasonably incidental thereto. The Issuer and each of the applicable Guarantors consents and agrees to be bound by the terms of the Collateral Agreements, as the same may be in effect from time to time, and agrees to perform its obligations thereunder in accordance therewith. Each Holder agrees that all Notes Obligations shall be and are secured equally and ratably by all Second Priority Liens at any time granted by the Issuer or any Guarantor to secure any Notes Obligations and all such Second Priority Liens shall be enforceable by the Collateral Agent for the benefit of all holders of Notes Obligations.

SECTION 11.2. Intercreditor Agreement . THIS INDENTURE, THE NOTES AND THE COLLATERAL AGREEMENTS ARE SUBJECT TO THE TERMS, LIMITATIONS AND CONDITIONS SET FORTH IN THE INTERCREDITOR AGREEMENT. THE TRUSTEE AND EACH HOLDER, BY ITS ACCEPTANCE OF A NOTE, IS DEEMED TO HAVE AUTHORIZED AND INSTRUCTED THE COLLATERAL AGENT TO ENTER INTO THE INTERCREDITOR AGREEMENT ON ITS BEHALF. Each Holder, by its acceptance of a Note, agrees that it will be bound by and will take no actions contrary to the provisions of the Intercreditor Agreement. In the event of any conflict or inconsistency between the provisions of this Indenture and the provisions of the Intercreditor Agreement, the provisions of the Intercreditor Agreement shall control. Nothing in the Indenture Documents (a) impairs, as between the Issuer and the Holders, the obligation of the Issuer to pay principal of and interest, premium, if any, on the Notes in accordance with their terms, (b) impairs, as between the Issuer and the Holders, subject to the preceding sentence, any other obligation of the Issuer or any Guarantor under the Indenture Documents, (c) restricts the right of any Holder to sue for payments that are then due and owing (but not the right to enforce any judgment in respect thereof against any Collateral to the extent prohibited by the Intercreditor Agreement) or (d) restricts or prevents any Holder or any other Person from exercising any of its rights or remedies upon a Default or in any insolvency or liquidation proceeding not restricted or prohibited by the Intercreditor Agreement.

SECTION 11.3. Release of Liens in Respect of the Notes . The Liens on Collateral securing the Notes Obligations will be entitled to be released upon any one or more of the following circumstances:

(1) in connection with a sale or other disposition of Collateral to a Person that is not the Issuer or a Restricted Subsidiary in accordance with the provisions of Section 4.10;

(2) if the Issuer exercises its Legal Defeasance option or its Covenant Defeasance option pursuant to Section 8.2 or Section 8.3 or if this Indenture is discharged in accordance with Section 8.8;

103

(3) in the event that the owner thereof is properly designated as an Unrestricted Subsidiary;

(4) in the event that the owner thereof ceases to be a Guarantor in accordance with this Indenture; provided that no continuing Event of Default relating to the failure to make required payments on the Notes exists;

(5) in whole or in part, in accordance with the provisions of Article IX; or

(6) otherwise as provided in the Intercreditor Agreement.

SECTION 11.4. Collateral Agent . (a) Each of the Holders by acceptance of the Notes hereby designates and appoints the Collateral Agent as its agent under this Indenture, the Collateral Agreements and the Intercreditor Agreement and each of the Holders by acceptance of the Notes hereby irrevocably authorizes the Collateral Agent to take such action on its behalf under the provisions of this Indenture and the Collateral Agreements (including the Intercreditor Agreement) and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Collateral Agreements (including the Intercreditor Agreement), and consents and agrees to the terms of the Intercreditor Agreement and each Collateral Agreement, as the same may be amended, restated, supplemented or otherwise modified from time to time in accordance with their respective terms. The provisions of this Section 11.4 are solely for the benefit of the Collateral Agent and none of the Trustee, any of the Holders nor any of the Guarantors or the Grantors shall have any rights as a third party beneficiary of any of the provisions contained herein. Each Holder agrees that any action taken by the Collateral Agent in accordance with the provisions of this Indenture and the Collateral Agreements (including the Intercreditor Agreement), and the exercise by the Collateral Agent of any rights or remedies set forth herein and therein shall be authorized and binding upon all Holders. Notwithstanding any provision to the contrary contained elsewhere in this Indenture and the Collateral Agreements (including the Intercreditor Agreement), the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the other Indenture Documents to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or fiduciary relationship with the Trustee, any Holder, any Guarantor or any Grantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Collateral Agreements (including the Intercreditor Agreement) or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(b) Subject to the provisions of the applicable Collateral Agreement, each Holder, by acceptance of the Notes, agrees that the Collateral Agent shall execute and deliver the Intercreditor Agreement and the other Collateral Agreements to which it is a party and all agreements, power of attorney, documents and instruments incidental thereto, and act in accordance with the terms thereof. The Collateral Agent shall hold (directly or through any

104

Agent) and is directed by each Holder to so hold, and shall be entitled to enforce on behalf of the holders of Notes Obligations all Second Priority Liens on the Collateral created by the Collateral Agreements for their benefit, subject to the provisions of the Intercreditor Agreement.

(c) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default, unless the Collateral Agent shall have received written notice from the Trustee or the Issuer referring to this Indenture, describing such Default and stating that such notice is a “notice of default.” The Collateral Agent shall take such action with respect to such Default as may be requested by the Trustee in accordance with Article VI or the Holders of a majority in aggregate principal amount of the Notes (subject to this Section 11.4).

(d) If at any time or times the Trustee shall receive (i) by payment, foreclosure, set-off or otherwise, any proceeds of Collateral or any payments with respect to the Notes Obligations except for any such proceeds or payments received by the Trustee from the Collateral Agent pursuant to the terms of this Indenture, or (ii) payments from the Collateral Agent in excess of the amount required to be paid to the Trustee pursuant to Article VI, the Trustee shall promptly turn the same over to the Collateral Agent, in kind, and with such endorsements as may be required to negotiate the same to the Collateral Agent, such proceeds to be applied by the Collateral Agent pursuant to the terms of this Indenture, the Intercreditor Agreement and the other Collateral Agreements.

(e) The Collateral Agent shall have no obligation whatsoever to the Trustee or any of the Holders to assure that the Collateral exists or is owned by any Grantor or Guarantor or is cared for, protected, or insured or has not been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Grantor’s property constituting Collateral intended to be subject to the Lien and security interest of the Collateral Agreements has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent pursuant to this Indenture, the Intercreditor Agreement or any other Collateral Agreements other than pursuant to the instructions of the Trustee or the Holders of a majority in aggregate principal amount of the Notes or as otherwise provided in the Collateral Agreements, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Collateral Agent shall have no other duty or liability whatsoever to the Trustee or any Holder or any Grantor or Guarantor as to any of the foregoing.

(f) The Collateral Agent may resign at any time by notice to the Trustee and the Issuer, such resignation to be effective upon the acceptance of a successor agent to its appointment as Collateral Agent. If the Collateral Agent resigns under this Indenture, the Issuer shall appoint a successor collateral agent. If no successor collateral agent is appointed prior to the intended effective date of the resignation of the Collateral Agent (as stated in the notice of resignation), the Collateral Agent may appoint, after consulting with the Trustee, subject to the consent of the Issuer (which shall not be unreasonably withheld and which shall not be required during a continuing Event of Default), a successor collateral agent. If no successor collateral agent is appointed and consented to by the Issuer pursuant to the preceding sentence within thirty

105

(30) days after the intended effective date of resignation (as stated in the notice of resignation) the Collateral Agent shall be entitled to petition a court of competent jurisdiction to appoint a successor. Upon the acceptance of its appointment as successor collateral agent hereunder, such successor collateral agent shall succeed to all the rights, powers and duties of the retiring Collateral Agent, and the term “Collateral Agent” shall mean such successor collateral agent, and the retiring Collateral Agent’s appointment, powers and duties as the Collateral Agent shall be terminated. After the retiring Collateral Agent’s resignation hereunder, the provisions of this Section 11.4 (and Article VI) shall continue to inure to its benefit and the retiring Collateral Agent shall not by reason of such resignation be deemed to be released from liability as to any actions taken or omitted to be taken by it while it was the Collateral Agent under this Indenture.

(g) Notwithstanding anything to the contrary in this Indenture or any other Indenture Document, in no event shall the Collateral Agent or the Trustee be responsible for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the security interests or Liens intended to be created by this Indenture or the other Indenture Documents (including without limitation the filing or continuation of any UCC financing statements, mortgages, security agreements or similar documents or instruments in any U.S. or foreign jurisdiction), nor shall the Collateral Agent or the Trustee be responsible for, and neither the Collateral Agent nor the Trustee makes any representation regarding, the validity, effectiveness or priority of any of the Collateral Agreements or the security interests or Liens intended to be created thereby.

(h) Notwithstanding anything to the contrary contained herein, the Collateral Agent shall act pursuant to the instructions of the Holders and the Trustee solely with respect to this Indenture, the Collateral Agreements and the Collateral.

SECTION 11.5. Compensation and Indemnity . (a) The Issuer and the Guarantors shall pay to the Collateral Agent from time to time such compensation as the Issuer and the Collateral Agent shall from time to time agree in writing for its services rendered under this Indenture, the Collateral Agreements and the Intercreditor Agreement. The Issuer and the Guarantors shall reimburse the Collateral Agent promptly upon request for all reasonable disbursements, expenses and advances incurred or made by it in addition to the compensation for its services, except any such disbursements, expenses and advances as may be attributable to the Collateral Agent’s gross negligence, bad faith or willful misconduct. Such expenses shall include the reasonable fees and expenses of the Collateral Agent’s agents, attorneys-in-fact and counsel, including but not limited to counsel in any U.S. or foreign jurisdiction.

(b) Each of the Issuer and the Guarantors, jointly and severally, shall indemnify the Collateral Agent (which for purposes of this Section 11.5(b) shall include its affiliates and the respective officers, directors, employees, agents, advisors and attorneys-in-fact of the Collateral Agent and its affiliates) against any and all claims, damages, losses, liabilities, costs or expenses incurred by it (including, without limitation, the fees and expenses of its agents, attorneys-in-fact and counsel) arising out of or in connection with the acceptance or administration of its duties under the Indenture Documents, the performance of its obligations and/or exercise of its rights under any Indenture Document, including the costs and expenses of enforcing this Indenture or any Collateral Agreement against the Issuer or any Guarantor (including this Section 11.5(b)) and defending itself against any claim (whether asserted by the Issuer or any Holder or any other

106

Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, claim, damage, liability or expense shall be caused by its own gross negligence, bad faith or willful misconduct. The Collateral Agent shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Collateral Agent to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Collateral Agent may have one separate counsel in each relevant jurisdiction, and the Issuer shall pay the fees and expenses of such counsel for the Collateral Agent. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The obligations of the Issuer and the Guarantors under this Section 11.5(b) shall survive the discharge of this Indenture, the payment of the Notes, the release or termination of any Second Priority Liens or the resignation or removal of the Collateral Agent.

Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “ Act ” of Holders signing such instrument or instruments.

Where such execution is by a signer acting in a capacity other than such signer’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of such signer’s authority.

SECTION 12.18. Conversion of Currency . If for the purposes of obtaining judgment in any court it is necessary to convert a sum due under this Indenture to the Holder from U.S. dollars to another currency, the Issuer and each Guarantor has agreed, and each Holder by holding such Note will be deemed to have agreed, to the fullest extent that the Issuer, each Guarantor and they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures such Holder could purchase U.S. dollars with such other currency in New York City, New York on the Business Day preceding the day on which final judgment is given.

The Issuer’s and Guarantors’ obligations to any Holder will, notwithstanding any judgment in a currency (the “ Judgment Currency ”) other than U.S. dollars, be discharged only to the extent that on the Business Day following receipt by such Holder or the Trustee, as the case may be, of any amount in such Judgment Currency, such Holder may in accordance with normal banking procedures purchase U.S. dollars with the judgment currency. If the amount of the

112

U.S. dollars so purchased is less than the amount originally to be paid to such Holder or the Trustee in the Judgment Currency (as determined in the manner set forth in the preceding paragraph), as the case may be, each of the Issuer and the Guarantors, jointly and severally, agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Holder and the Trustee, as the case may be, against any such loss. If the amount of the U.S. dollars so purchased is more than the amount originally to be paid to such Holder or the Trustee, as the case may be, such Holder or the Trustee, as the case may be, will pay the Issuer and the Guarantors, such excess; provided that such Holder or the Trustee, as the case may be, shall not have any obligation to pay any such excess as long as a Default under the Notes or this Indenture has occurred and is continuing or if the Issuer or the Guarantors shall have failed to pay any Holder or the Trustee any amounts then due and payable under such Note or this Indenture, in which case such excess may be applied by such Holder or the Trustee to such Obligations.

SECTION 12.19. Service of Process . Each of the Issuer and each non-U.S. Guarantor hereby appoints McDermott, Inc., as its agent for service of process in any suit, action or proceeding with respect to this Indenture, the Notes or the Guarantees and for actions brought under federal or state securities laws brought in any federal or state court located in The City of New York.

SECTION 12.20. Legal Holidays . If any payment date falls on a day that is not a Business Day, the payment to be made on such payment date will be made on the next succeeding Business Day with the same force and effect as if made on such payment date, and no additional interest will accrue solely as a result of such delayed payment.
