If a Person other than the Indenture Trustee is appointed by the Issuer to maintain the Note Register, the Issuer will give the Indenture Trustee and the Administrative Agent prompt written notice of such appointment and of the location, and any change in the location, of the successor note registrar, and the Indenture Trustee, the Issuer, the Servicer and the related Series Enhancer shall have the right to inspect the Note Register at all reasonable times and to obtain copies thereof, and the Indenture Trustee shall have the right to rely upon a certificate executed on behalf of the note registrar by an officer thereof as to the names and addresses of the Noteholders and the principal amounts and number of such Notes.

The principal of, premium, if any, and interest on each Note shall be payable at the Corporate Trust Office of the Indenture Trustee in immediately available funds in such coin or currency of the United States of America as at the time for payment shall be legal tender for the payment of public and private debts. Except as set forth in any Supplement, all interest payable on the Notes shall be computed on the basis of a year of 360 days for the actual number of days (including the first but excluding the last day) elapsed. Notwithstanding the foregoing or any provision in any Note to the contrary, if so requested by the registered Holder of any Note by written notice to the Indenture Trustee received by the Indenture Trustee at least 5 Business Days prior to the Payment Date, all amounts payable to such registered Holder may be paid either (i) by crediting the amount to be distributed to such registered Holder to an account maintained by such registered Holder with the Indenture Trustee or by transferring such amount by wire to such other bank in the United States, including a Federal Reserve Bank, as shall have been specified in such notice, for credit to the account of such registered Holder maintained at such bank, or (ii) by mailing a check to such address as such Holder shall have specified in such notice, in either case without any presentment or surrender of such Note to the Indenture Trustee at the Corporate Trust Office of the Indenture Trustee.

Upon satisfaction of the requirements set forth in the preceding sentence, each Holder of a Note shall have the right, upon surrender of such Note to the Indenture Trustee, to require a new Note or Notes of the same Series and Class to be issued to it or to a prospective Holder, in a minimum denomination of the lesser of (x) $1,000,000 (or such other amount as shall be set forth in the related Supplement) or (y) the entire principal balance of the Note being surrendered, in substitution of the Note being surrendered.

(d) Any service charge made or expense incurred by the Indenture Trustee for any such registration, discharge from registration or exchange referred to in this Section 205 shall be paid by the Noteholder. The Indenture Trustee or the Issuer may require payment by the Holder of a sum sufficient to cover any tax, expense or other governmental charge payable in connection therewith.

(e) Each prospective initial Noteholder acquiring a Note, each prospective owner acquiring a Note and each prospective owner (or transferee thereof) of a beneficial interest in Notes acquiring such beneficial interest shall represent and warrant in writing to the Indenture Trustee, the Issuer, the Servicer and any successor Servicer that one of the following statements is true and correct: (i) the purchaser is not an “employee benefit plan” within the meaning of Section 3(3) of ERISA or a “plan” within the meaning of Section 4975(e)(1) of the Code (“Benefit Plan”) and it is not directly or indirectly acquiring the Notes on behalf of, as investment manager of, as named fiduciary of, as trustee of, or with assets of, a Benefit Plan, (ii) the acquisition will qualify for a statutory or administrative prohibited transaction exemption under ERISA and the Code and will not give rise to a non-exempt transaction described in

(f) No transfer of any Note shall be made unless such transfer is made in a transaction which does not require registration under the Securities Act and pursuant to an effective registration or qualification under any State securities or “Blue Sky” laws, or in a transaction which does not require such registration or qualification. If such a transfer is to be made in reliance upon an exemption from the Securities Act other than Rule 144A under the Securities Act, the prospective owner shall furnish to the Indenture Trustee a certificate substantially in the form of Exhibit E hereto. If such transfer is to be made in reliance upon Rule 144A under the Securities Act, the prospective owner shall furnish to the Indenture Trustee a certificate, substantially in the form of Exhibit D hereto. The Issuer (or Servicer as agent for the Issuer) shall promptly furnish to any Holder, or any prospective owners designated by a Holder, the information required to be delivered to any Holder and prospective owner in connection with a resale of the Notes to permit compliance with Rule 144A in connection with such resale. No Note may be subdivided (including any assignment or transfer of a participation or beneficial interest therein) for resale or other transfer into a unit smaller than a unit the initial offering price of which would have been $1,000,000 (or such other amount as shall be set forth in the related Supplement).

(g) No transfer of any Note shall be made unless (A) the prospective transferee of such Note shall represent and warrant in writing to the Indenture Trustee, the Issuer, the Servicer and any successor Servicer that: (i) it constitutes no more than [insert number] “beneficial owners” of the Notes for purposes of Section 3(c)(1) of the Investment Company Act; (ii) it is investing no more than 40% of its assets in any Notes issued under this Indenture; (iii) it was not formed for the purpose of investing in any Notes issued under this Indenture; (iv) (a) the shareholders, partners or other holders of equity or beneficial interests in the prospective transferee are not able to decide individually whether to acquire such Note or to determine the extent of such acquisition and (b) it is not a defined contribution or similar benefit plan that allows participants to determine whether or how much will be invested in investments on their behalf; (v) it is acquiring such Note in a principal amount of not less than the minimum denominations set forth in the Indenture; and (vi) it is acquiring the Notes for investment and not for sale in connection with any distribution thereof; and (B) the Issuer has consented to such

Section 206. Mutilated, Destroyed, Lost and Stolen Notes. (a) If (i) any mutilated Note is surrendered to the Indenture Trustee, or the Indenture Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, and (ii) there is delivered to the Indenture Trustee such security or indemnity as it and the Issuer may require to hold the Issuer, the Servicer and the Indenture Trustee harmless (the unsecured indemnity of a Rated Institutional Noteholder being deemed satisfactory for such purpose unless the Indenture Trustee provides written notice to the contrary), then the Issuer shall execute and the Indenture Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Note, a replacement Note of the same Series and Class and maturity and of like terms as the mutilated, destroyed, lost or stolen Note; provided, however, that if any such destroyed, lost or stolen Note, but not a mutilated Note, shall have become, or within seven days shall be, due and payable, or shall have been called for redemption, the Issuer may pay such destroyed, lost or stolen Note when so due or payable instead of issuing a replacement Note.

(b) If, after the delivery of such replacement Note, or payment of a destroyed, lost or stolen Note pursuant to the proviso in the preceding sentence, a bona fide purchaser of the original Note in lieu of which such replacement Note was issued presents for payment such original Note, the Issuer and the Indenture Trustee shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Issuer or the Indenture Trustee in connection therewith.

(c) The Indenture Trustee and the Issuer may, for each new Note authenticated and delivered under the provisions of this Section 206, require the advance payment by the Noteholder of the expenses, including counsel fees, service charges and any tax or governmental charge which may be incurred by the Indenture Trustee or the Issuer. Any Note issued under the provisions of this Section 206 in lieu of any Note alleged to be destroyed, mutilated, lost or stolen, shall be equally and proportionately entitled to the benefits of this Indenture with all other Notes of the same Series and Class. The provisions of this Section 206 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

Section 207. Delivery, Retention and Cancellation of Notes. Each Noteholder is required, and hereby agrees, to return to the Indenture Trustee, within 30 days after the Final Payment Date, any Note on which the final payment due thereon has been made. Any such Note as to which the Indenture Trustee has made or holds the final payment thereon shall be deemed cancelled and shall no longer be Outstanding or outstanding for any purpose of this Indenture, whether or not such Note is ever returned to the Indenture Trustee unless any unreimbursed payment on such Note has been made by a Series Enhancer. Matured Notes delivered upon final payment to the Indenture Trustee and any Notes transferred or exchanged for other Notes shall be cancelled and disposed of by the Indenture Trustee in accordance with its policy of disposal and the Indenture Trustee shall promptly deliver to the Issuer such cancelled Notes upon request; provided, however, that the Indenture Trustee shall not be required to destroy cancelled Notes. If the Indenture Trustee, for its own account, shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes. If the

Issuer shall acquire any of the Notes, such acquisition shall operate as a redemption or satisfaction of the indebtedness represented by such Notes. Notes which have been cancelled by the Indenture Trustee shall be deemed paid and discharged for all purposes under this Indenture.

Section 303. Trust Account. (a) On or prior to the Effective Date of the first Series, the Issuer shall, and will cause WLFC Funding (Ireland) Limited to, establish and maintain the Trust Account into which all Collections (other than amounts received from manufacturers or sellers of an Eligible Engine for breach of sale warranties or in settlement of any claims, losses, disputes or proceedings related thereto for which a corresponding amount has previously been paid by the Issuer, WLFC Funding (Ireland) Limited, Seller or Servicer to the Trust Account), Prepayments after an Early Amortization Event, Prepayments designated by the Issuer or WLFC Funding (Ireland) Limited to be deposited in the Trust Account prior to the occurrence of an Early Amortization Event, Warranty Purchase Amounts and other payments required by this Indenture shall be deposited. Such Trust Account shall be established and maintained with the Corporate Trust Office of the Indenture Trustee in trust for the Indenture Trustee, on behalf of the Noteholders and any Series Enhancer, until the Aggregate Outstanding Obligations are paid in full. The Trust Account shall be an Eligible Account and shall be pledged to the Indenture Trustee pursuant to the terms of this Indenture (or, in the case of the Trust Account maintained by WLFC Funding (Ireland) Limited, pursuant to an instrument in form and substance satisfactory to the Deal Agent for each Series which the Issuer will cause WLFC Funding (Ireland) Limited to execute and deliver). Promptly upon receipt thereof (but in no event later than two Business Days after receipt), the Servicer shall deposit into the Trust Account those amounts that have been remitted directly to the Servicer that the Servicer ascertains to be Engine Revenues, Sales Proceeds or Casualty Proceeds in respect of any of the Eligible Engines; provided, however, that indemnification payments and liability insurance payments received by the Issuer, WLFC Funding (Ireland) Limited or the Servicer shall not be

In addition, the Servicer shall instruct in writing the Indenture Trustee to allocate any earnings on Eligible Investments in the Trust Account to the Series Account for each Series then Outstanding in the same proportion as the ratio of the Outstanding Obligations of such Series to the Aggregate Outstanding Obligations.

(c) If any Series has more than one Class of Notes then Outstanding, then the portion of the investment earnings in the Trust Account allocable to such Series pursuant to Section 303(b) shall be calculated without giving effect to the payment priorities of the Classes of such Series. Once such Collections and investment earnings have been allocated to each Series, then that portion of the Collections allocable to such Series shall be paid to each Class of Noteholders of such Series in accordance with the priority of payments set forth in the related Supplement.

Section 304. Investment of Monies Held in the Trust Account, the Restricted Cash Account, Engine Reserve Account, the Security Deposit Account and Series Accounts.

Each Eligible Investment (including reinvestment of the income and proceeds of Eligible Investments) shall be held to its maturity and shall mature or shall be payable on demand not later than the Business Day immediately preceding the next succeeding Payment Date. If the Indenture Trustee has not received written instructions from the Servicer by 2:30 p.m. (New York time) on the day such funds are received as to the investment of funds then on deposit in any of the aforementioned accounts, the Issuer hereby instructs the Indenture Trustee to, and will cause WLFC Funding (Ireland) Limited to instruct the Indenture Trustee to, invest such funds in overnight investments of the type described in clause (ii) of the definition of Eligible Investments.

(b) The Issuer shall maintain (or shall cause the Servicer to maintain) records that will identify amounts on deposit in the Engine Reserve Account subaccount to a specific Eligible Engine. The Servicer shall be entitled to withdraw funds from the Engine Reserve Account for the payment of maintenance expenses with respect to the related Eligible Engine, at the times and subject to the further conditions set forth in the Servicing Agreement; provided, however, that so long as a Servicer Default is then in effect, the Servicer shall not be entitled to make such withdrawal except upon presentation of supporting documentation reasonably determined by the Administrative Agent to comply with the terms of the applicable Lease Agreement (which shall evidence its determination by written instrument delivered to the Indenture Trustee).

Section 309. Security Deposit Account.

(b) Each of the Issuer, the Securities Intermediary and the Indenture Trustee intends that the provisions of Section 310(a) will give the Indenture Trustee “control” over the Securities Accounts (as the term “control” is defined under UCC Section 8-106(d)), without prejudice to any other provision of the UCC that also would be deemed to give the Indenture Trustee such control.

ARTICLE IV

COLLATERAL

Section 401. Collateral. (a) The Notes and the obligations of the Issuer hereunder shall be an obligation of the Issuer as provided in Section 203 hereof. The Indenture Trustee, for the benefit of the Noteholders of all Series, and the Noteholders of a particular Series and the Series Enhancer (if any) of such Series, all in accordance with the Supplement for such Series, shall also have the benefit of, and the Notes of such Series shall be secured by and be payable from, the Issuer’s right, title and interest in that portion of the Collateral allocated or identified to such Series in accordance with the terms of this Indenture and the Supplement pursuant to which such Notes were issued.

(c) Pursuant to the Servicing Agreement the Issuer shall cause the Servicer to collect the Accounts in accordance with the Servicer’s normal business practice; provided, however, that the Indenture Trustee, with the consent of, or at the direction of, the Requisite Global Majority, may, without notice, limit or terminate such authority upon (i) the occurrence of an Event of Default described in Section 801(ii) hereof, or (ii) any Sale of the Collateral pursuant to Section 816 hereof or (iii) the occurrence of a Servicer Default. Any Proceeds subsequently received in payment of any such Account or in payment for any of the Eligible Engines or on account of any of its Contracts shall be promptly deposited by the Issuer in precisely the form received (with all necessary endorsements) in the Trust Account as hereinafter provided, and until so turned over shall be deemed to be held in trust by the Issuer for and as the Indenture Trustee’s property. Such Proceeds, when deposited, shall continue to be collateral security for all of the obligations secured by this Indenture and shall not constitute payment thereof until applied as hereinafter provided. Upon (i) the occurrence of an Event of Default described in Section 801(ii), or (ii) any Sale of the Series Collateral pursuant to Section 816 hereof or (iii) the occurrence of a Servicer Default, the Issuer shall at the request of the Indenture Trustee, with the consent of or at the direction of the Requisite Global Majority, to the extent practicable, deliver to the Indenture Trustee (or such other Person as the Indenture Trustee may direct) all original Lease Agreements and any other documents evidencing, and relating to, the sale, lease and delivery of the Eligible Engines and the Issuer shall, to the extent practicable, deliver all original and other documents evidencing and relating to, the performance of any labor, maintenance, remarketing or other service which gave rise to such Accounts, including, without limitation, all original orders, invoices and shipping receipts.

Such Excess Cash Available for Distribution shall be paid to the Indenture Trustee(s) for each such Deficient Series in the proportion that the Outstanding Obligations for each such Deficient Series bears to the aggregate amount of Outstanding Obligations for all such Deficient Series. Only after all Deficiency Amounts existing on such Payment Date have been paid in full shall any such Excess Cash Available for Distribution be paid to the Issuer.

Section 402. Pro Rata Interest. (a) Each Supplement pursuant to which a Series of Notes is issued shall identify the Eligible Engines and other Series Collateral that will be pledged as collateral security for the Notes and other Obligations for such Series. All Notes of a particular Series shall be equally and ratably entitled to the benefits of this Indenture without preference, priority or distinction, except as provided in the related Supplement. All Notes of a particular Class within a Series are and are to be, to the extent (including any exceptions)

provided in this Indenture and the related Supplement, equally and ratably secured by this Indenture without preference, priority or distinction on account of the actual time or times of the authentication or delivery of the Notes so that all Notes of a particular Series and Class at any time Outstanding shall have the same right, Lien and preference under this Indenture and shall all be equally and ratably secured hereby with like effect as if they had all been executed, authenticated and delivered simultaneously on the date hereof.

(b) With respect to each Series of Notes, the execution and delivery of the related Supplement shall be upon the express condition that if the conditions specified in Section 701 of this Indenture are met with respect to such Series of Notes, the security interest and all other estate and rights granted by this Indenture with respect to such Series of Notes shall cease and become null and void and all of the property, rights and interest granted as security for the Notes of such Series shall revert to and revest in the Issuer without any other act or formality whatsoever.

Section 403. Indenture Trustee’s Appointment as Attorney-in-Fact. (a) The Issuer hereby irrevocably constitutes and appoints the Indenture Trustee, and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Issuer and in the name of the Issuer or in its own name, from time to time at the Indenture Trustee’s discretion, for the purpose of carrying out the terms of this Indenture, to take any and all appropriate action and to execute and deliver any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Indenture; provided, however, that the Indenture Trustee has no obligation or duty to determine whether to perfect, file, record or maintain any perfected, filed or recorded document or instrument in connection with the grant or security interest in the Collateral hereunder.

The power of attorney granted pursuant to this Section 403 is a power coupled with an interest and shall be irrevocable until all Series of Notes are paid and performed in full.

(c) The powers conferred on the Indenture Trustee hereunder are solely to protect the Indenture Trustee’s interests in the Collateral and shall not impose any duty upon it to exercise any such powers except as set forth herein. The Indenture Trustee shall be accountable only for amounts that it actually receives as a result of the exercise of such powers and neither it nor any of its officers, directors, employees, agents or representatives shall be responsible to the Issuer for any act or failure to act, except for its own negligence or willful misconduct.

(d) The Issuer also authorizes the Indenture Trustee, at any time and from time to time upon the occurrence of any Event of Default (subject to the quiet enjoyment rights of any lessee of any Collateral), to (i) communicate in its own name, or to direct any other Person, including the Servicer or a successor Servicer, to communicate with any party to any Contract with regard to the assignment of the right, title and interest of the Issuer in and under the Contracts hereunder and other matters relating thereto and (ii) execute, in connection with the

sale of Collateral provided for in Article VIII hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral.

(e) If the Issuer fails to perform or comply with any of its agreements contained herein and the Indenture Trustee, with the consent of or at the direction of the Requisite Global Majority, shall perform or comply, or otherwise cause performance or compliance, with such agreement, the reasonable expenses, including attorneys’ fees, of the Indenture Trustee incurred in connection with such performance or compliance together with interest thereon at the rate specified in the related Supplement, shall be payable by the Issuer to the Indenture Trustee on demand and shall constitute obligations secured hereby.

Section 404. Release of Security Interest. The Indenture Trustee, at the written direction of the Servicer (and with the prior written consent of the Administrative Agent if an Early Amortization Event shall have occurred), shall release from the security interest created pursuant to the terms of this Indenture, any Eligible Engine, the related Lease Agreement and any other Related Assets sold or transferred pursuant to Section 606(a) hereof. In effectuating such release, the Indenture Trustee shall be entitled to rely on a certificate of the Servicer (provided, however, that after the occurrence of an Early Amortization Event, the Administrative Agent in its sole discretion shall be entitled to deliver such certification) identifying each Eligible Engine, the related Lease Agreement or other items to be released from the Lien of this Indenture in accordance with the provisions of this Section 404 accompanied by an Asset Base Certificate and stating that such release is in compliance with Sections 404 and 606(a) hereof.

The Indenture Trustee will, promptly upon receipt of such certificate from the Servicer or the Administrative Agent and at the Issuer’s expense, execute and deliver to the Issuer, the Seller or the Servicer, as appropriate, and each Series Enhancer, a non-recourse certificate of release substantially in the form of Exhibit F hereto and such additional documents and instruments as that Person may reasonably request (including UCC termination statements and appropriate filings with the FAA or other Governmental Authority) to evidence the termination and release from the Lien of this Indenture of such Eligible Engine, the related Lease Agreement and the other related items of Collateral.

Section 405. Administration of Collateral. (a) The Indenture Trustee hereby acknowledges the appointment by the Issuer of the Servicer to service and administer the Collateral in accordance with the provisions of the Servicing Agreement and agrees to provide the Servicer with such documentation, and to take all such actions, as the Servicer may reasonably request in accordance with the provisions of the Servicing Agreement or as the Issuer may request.

(b) The Indenture Trustee shall as promptly as practicable notify the Noteholders, each Series Enhancer and the Administrative Agent of any Servicer Default of which it has prior actual knowledge, and at the direction of the Requisite Global Majority, shall deliver to the Servicer a Servicer Termination Notice terminating the Servicer of its responsibilities in accordance with the terms of the Servicing Agreement. If the Administrative Agent is unable to locate and qualify a successor Servicer within sixty (60) days after the date of delivery of the Servicer Termination Notice, then the Indenture Trustee may appoint, or petition a court of competent jurisdiction to appoint, a company acceptable to the Requisite Global

Majority, and whose regular business includes equipment leasing, as the successor to the Servicer of all or any part of the responsibilities, duties or liabilities of the Servicer under the Servicing Agreement, for such portion of the Servicing Fee as the Requisite Global Majority shall determine in its sole discretion. The Servicer shall continue to fulfill its duties and responsibilities as Servicer until such time as its replacement is appointed and has assumed such responsibilities. The replaced Servicer shall not be entitled to receive any compensation for any period after the effective date of such replacement, but shall be entitled to receive compensation for services rendered through the effective date of such replacement except to the extent that it is unable to fulfill such duties pending the appointment of a successor Servicer. If the Servicer is unable to fulfill such duties pending the appointment of a successor Servicer, the Administrative Agent may (but shall not be required to) take such actions which it is reasonably capable of performing and that have been directed by the Requisite Global Majority; provided, however, that as a condition precedent to taking any such action, the Requisite Global Majority shall provide the Administrative Agent with (i) indemnification, reasonably satisfactory to the Administrative Agent, with respect to such actions and (ii) reimbursement of any out-of-pocket costs incurred by the Administrative Agent in taking such actions which have been approved by the Requisite Global Majority. In connection with the appointment of a successor Servicer, the Indenture Trustee or Administrative Agent may, with the written consent of the Requisite Global Majority, make such arrangements for the compensation of such replacement out of Collections as the Indenture Trustee, the Administrative Agent and such successor Servicer shall agree; provided, however, that no such revised compensation shall be in excess of the Servicing Fees permitted the Servicer under the Servicing Agreement and the arrangement for reimbursement of expenses shall be no more favorable than that set forth in the Servicing Agreement unless (i) the Indenture Trustee (with the prior written consent of the Requisite Global Majority) shall approve such higher amounts or (ii) the outgoing Servicer shall agree to pay, out of its own funds, the successor Servicer any such excess compensation and reimbursement; provided, further, that in no event shall either the Indenture Trustee or the Administrative Agent be liable to any successor Servicer for the Servicing Fees or any additional amounts (including expenses and indemnifications) payable to such successor Servicer, either pursuant to the Servicing Agreement or otherwise. The Indenture Trustee and such successor shall take such action, consistent with the Servicing Agreement, as shall be necessary to effectuate any such succession.

(c) The Indenture Trustee may, and shall if directed by the Requisite Global Majority, at any time, upon the occurrence of any Servicer Default, after first notifying the Issuer of its intention to do so, notify Account Debtors of the Issuer, parties to the Contracts of the Issuer, obligors in respect of Instruments of the Issuer and obligors in respect of Chattel Paper of the Issuer that the Accounts and the right, title and interest of the Issuer in and under such Contracts, Instruments, and Chattel Paper (to the extent related to the Eligible Engines) have been assigned to the Indenture Trustee and that payments shall be made directly to the Indenture Trustee; provided that a successor Servicer appointed pursuant to this Section 405 shall unless otherwise directed by the Requisite Global Majority, exercise all of the foregoing rights, and that pending appointment of such successor Servicer, the then current Servicer shall unless otherwise directed by the Requisite Global Majority be permitted to exercise such rights until the successor Servicer assumes the responsibility of the Servicer. Upon the request of the Requisite Global Majority, the Issuer or Servicer shall so notify such Account Debtors, parties to such Contracts, obligors in respect of such Instruments and obligors in respect of such Chattel Paper. Upon the occurrence of a Servicer Default, the Indenture Trustee shall at the direction of the Requisite

Global Majority communicate with such Account Debtors, parties to such Contracts, obligors in respect of such Instruments and obligors in respect of such Chattel Paper to verify with such parties, to the Indenture Trustee’s satisfaction, the existence, amount and terms of any such Accounts, Contracts, Instruments or Chattel Paper.

(d) Upon the breach of any Engine Representations and Warranties giving rise to repurchase or substitution obligations of the Seller pursuant to Section 2.02 of the Contribution and Sale Agreement, the Issuer shall cause the Seller to fully satisfy such repurchase or substitution obligations and cause to be deposited in the Trust Account in accordance with the provisions of Section 2.02 of the Contribution and Sale Agreement, the Warranty Purchase Amounts received from, or on behalf of, the Seller with respect to such repurchase obligation. Upon obtaining actual knowledge or the receipt of notice by the Indenture Trustee that any repurchase or substitution obligations of the Seller under Section 2.02 of the Contribution and Sale Agreement have arisen, the Indenture Trustee shall notify the Series Enhancer, if any, for the Series to which the Engines to be repurchased or substituted are pledged, each Rating Agency and all Noteholders of the Series to which such Engines are pledged of such event and shall enforce such repurchase or substitution obligations at the direction of the Control Party for the affected Series.

Section 406. Quiet Enjoyment. The security interest hereby granted to the Indenture Trustee by the Issuer is subject to the rights of any lessee under the related Lease Agreement so long as such lessee is not in default under the Lease Agreement therefor and the Servicer under the Servicing Agreement (or the Indenture Trustee, as provided in Section 405(c)) continues to receive all amounts payable under the related Contract.

Section 407. Acknowledgment. The Indenture Trustee agrees to execute any and all acknowledgments that the Issuer or the Seller may require with respect to the Lessee’s right to continued quiet enjoyment of the related Engine.

(ii) all Events of Default, other than the nonpayment of the principal of or interest on Notes which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 813 hereof.

No such rescission with respect to any Event of Default shall affect any subsequent Event of Default or impair any right consequent thereon.

Section 803. Collection of Indebtedness. The Issuer covenants that, if an Event of Default occurs and is continuing and a declaration of acceleration has been made under Section 802 with respect to a Series and not rescinded, the Issuer will, upon demand of the Indenture Trustee, pay to the Indenture Trustee, for the benefit of the Noteholders of such Series then Outstanding and any Series Enhancers of such Series, an amount equal to the sum of (i) the Outstanding Obligations of such Series including the costs and out-of-pocket expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee, its agents and counsel incurred in connection with the enforcement of this Indenture and (ii) to the extent that the payment of such interest is lawful, interest on the amount set forth in clause (i) at the applicable Overdue Rate.

Section 805. Indenture Trustee May Enforce Claims Without Possession of Notes. (a) In all Proceedings brought by the Indenture Trustee (and also any Proceedings involving the interpretation of any provision of this Indenture to which the Indenture Trustee shall be a party), the Indenture Trustee shall be held to represent all of the Noteholders of the affected Series, and it shall not be necessary to make any affected Noteholder a party to any such Proceedings.

(b) All rights of action and claims under this Indenture, the related Supplement or such Notes may be prosecuted and enforced by the Indenture Trustee without the possession of any of the Notes or the production thereof in any Proceeding relating thereto, and any such Proceeding instituted by the Indenture Trustee shall be brought in its own name as trustee of an express trust, and any recovery whether by judgment, settlement or otherwise shall, after provision for the payment of the reasonable compensation, expenses, and disbursements incurred and advances made, by the Indenture Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes of the affected Series, subject to the subordination of payments among Classes of a particular Series as set forth in the related Supplement.

Section 806. Allocation of Money Collected. If the Notes of a Series have been declared due and payable following an Event of Default and such declaration and its

consequences have not been rescinded or annulled, any money collected by the Indenture Trustee pursuant to this Article or otherwise and any other monies that may be held or thereafter received by the Indenture Trustee as security for the Notes of such Series shall be applied, to the extent permitted by law, in the following order, at the date or dates fixed by the Indenture Trustee:

FIRST: To the payment of all amounts due the Indenture Trustee under Section 905 hereof; and

SECOND: To the payment of all management fees or other servicing fees as more particularly provided in each Supplement and in accordance with the terms of the related Servicing Agreement: provided, however, that in no event shall the Servicing Fee then payable pursuant to each Supplement be less than the Minimum Servicing Fee Percentage of Engine Revenues of the Engines pledged pursuant to such Supplement.

THIRD: Any remaining amounts shall be distributed in accordance with Section 3.02 (II) of each Supplement (or such other or additional related sections or clauses as may be provided in any particular Supplement) hereof but without duplication of any amounts specified in Section 3.02(II) of a Supplement that is also set forth in Section 806 (First) or (Second) above.

Section 807. Limitation on Suits. Except to the extent provided in Section 808 hereof, no Noteholder of a Series shall have the right to institute any Proceeding, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(ii) the Control Party of such Series shall have made written request to the Indenture Trustee to institute Proceedings in respect of such Event of Default in its own name as Indenture Trustee hereunder;

(iii) such Holder or Holders have offered to the Indenture Trustee reasonable security or indemnity against the costs, expenses and liabilities to be incurred in compliance with such request (the unsecured indemnity of a Rated Institutional Noteholder being deemed satisfactory for such purpose);

(iv) the Indenture Trustee has, for 30 days after its receipt of such notice, request and offer of security or indemnity, failed to institute any such Proceeding; and

(v) no direction inconsistent with such written request has been given to the Indenture Trustee during such 30 day period by the Control Party of such Series;

it being understood and intended that no one or more Noteholders shall have any right in any manner whatsoever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Noteholder, or to obtain or to seek to obtain priority or preference over any other Noteholder (except to the extent provided in the related

Supplement) or to enforce any right under this Indenture, except in the manner herein provided and for the benefit of all Noteholders of a Series.

Section 808. Unconditional Right of Holders to Receive Principal and Interest. Notwithstanding any other provision of this Indenture, each Noteholder shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest on such Note as such principal and interest becomes due and payable and to institute any Proceeding for the enforcement of such payment, and such rights shall not be impaired without the consent of such Holder.

Section 809. Restoration of Rights and Remedies. If the Indenture Trustee, any Series Enhancer or any Holder has instituted any Proceeding to enforce any right or remedy under this Indenture or the related Supplement and such Proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Indenture Trustee, any Series Enhancer or to such Holder, then and in every such case, subject to any determination in such Proceeding, the Issuer, the Indenture Trustee, such Series Enhancer (if applicable) and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Indenture Trustee, such Series Enhancer (if applicable) and the Holders shall continue as though no such Proceeding had been instituted.

Section 810. Rights and Remedies Cumulative. No right or remedy conferred upon or reserved to the Indenture Trustee, any Series Enhancer (if applicable) or to the Holders pursuant to this Indenture or any Supplement is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 811. Delay or Omission Not Waiver. No delay or omission of the Indenture Trustee, of any Series Enhancer or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Indenture Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or by the Holders, as the case may be.

Section 812. Control by the Control Party of the Affected Series. Upon the occurrence of an Event of Default with respect to a Series, the Control Party of the affected Series shall have the right to direct the time, method and place of conducting any Proceeding for any remedy available to the Indenture Trustee or exercising any trust or power conferred on the Indenture Trustee, provided that (i) such direction shall not be in conflict with any rule of law or with this Indenture, including, without limitation, Section 804 hereof, (ii) such Control Party has offered to the Indenture Trustee reasonable security or indemnity against costs, expenses and liabilities which it might incur in connection therewith as provided in Section 902(iii) hereof, and (iii) the Indenture Trustee may take any other action deemed proper by the Indenture Trustee which is not inconsistent with such direction.

Section 813. Waiver of Past Defaults. (a) The Control Party of a Series may, on behalf of all Noteholders of such Series, waive any past Event of Default with respect to such Series and its consequences, except an Event of Default with respect to such Series:

(i) in the payment of (x) the principal balance of any Note on the Final Payment Date or (y) any required interest payment on any Note of any Series on any Payment Date, or

(ii) in respect of a covenant or provision hereof which cannot be modified or amended without the consent of all the Noteholders of all Series pursuant to Section 1002 of this Indenture.

(b) Upon any such waiver, such Event of Default shall cease to exist and shall be deemed to have been cured and not to have occurred for every purpose of this Indenture; provided, however, that no such waiver shall extend to any subsequent or other Event of Default or impair any right consequent thereon.

Section 814. Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Note by acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Indenture Trustee for any action taken, suffered or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, however, that the provisions of this Section 814 shall not apply (i) to any suit instituted by the Indenture Trustee or any Holder or group of Holders, holding in the aggregate more than 10% of the aggregate principal balance of the Notes of all Series then Outstanding, or (ii) to any suit instituted by any Holder for the enforcement of (x) the payment of interest or principal on any Notes on any Payment Date or (y) the payment of the principal of any Note on or after the Final Payment Date of such Note.

Section 815. Waiver of Stay or Extension Laws. The Issuer covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 816. Sale of Collateral. (a) The power to effect any sale (a “Sale”) of any portion of the Series Collateral pursuant to Section 804 hereof shall not be exhausted by any one or more Sales as to any portion of the Series Collateral remaining unsold, but shall continue unimpaired until the entire Series Collateral shall have been sold or the Outstanding Obligations of the related Series shall have been paid in full. The Indenture Trustee at the direction of the

Control Party of the related Series may from time to time postpone any Sale by public announcement made at the time and place of such Sale.

(b) Upon any Sale, whether made under the power of sale hereby given or under judgment, order or decree in any Proceeding for the foreclosure or involving the enforcement of this Indenture: (i) the Indenture Trustee, at the direction of the Control Party of the related Series, may bid for and purchase the property being sold, and upon compliance with the terms of such Sale may hold, retain and possess and dispose of such property in accordance with the terms of this Indenture; and (ii) the receipt of the Indenture Trustee or of any officer thereof making such Sale shall be a sufficient discharge to the purchaser or purchasers at such Sale for its or their Purchase money, and such purchaser or purchasers, and its or their assigns or personal representatives, shall not, after paying such purchase money and receiving such receipt of the Indenture Trustee or of such officer therefor, be obliged to see to the application of such purchase money or be in any way answerable for any loss, misappropriation or non-application thereof.

(c) The Indenture Trustee shall execute and deliver an appropriate instrument of conveyance transferring its interest in any portion of the Collateral in connection with a Sale thereof. In addition, the Indenture Trustee is hereby irrevocably appointed the agent and attorney-in-fact of the Issuer to transfer and convey its interest (subject to lessee’s rights of quiet enjoyment) in any portion of the Collateral in connection with a Sale thereof, and to take all action necessary to effect such Sale. No purchaser or transferee at such a Sale shall be bound to ascertain the Indenture Trustee’s authority, inquire into the satisfaction of any conditions precedent or see to the application of any monies.

Section 817. Action on Notes. The Indenture Trustee’s right to seek and recover judgment on the Notes or under this Indenture or any Supplement shall not be affected by the seeking, obtaining or application of any other relief under or with respect to this Indenture or any Supplement. Neither the Lien of this Indenture nor any rights or remedies of the Indenture Trustee, any Series Enhancer or the Noteholders shall be impaired by the recovery of any judgment by the Indenture Trustee against the Issuer or by the levy of any execution under such judgment upon any portion of the Collateral or upon any of the assets of the Issuer.

ARTICLE IX

CONCERNING THE INDENTURE TRUSTEE

Section 901. Duties of Indenture Trustee. The Indenture Trustee, prior to the occurrence of an Event of Default with respect to any Series or after the curing of any Event of Default with respect to any Series which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and the related Supplement. If an Event of Default with respect to any Series has occurred and is continuing, the Indenture Trustee, at the direction of the Control Party of the related Series, shall exercise such of the rights and powers vested in it by this Indenture and the related Supplement, and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

The Indenture Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Indenture Trustee which are specifically required to be furnished pursuant to any provisions of this Indenture and any applicable Supplement, shall determine whether they are in the form required by this Indenture and any applicable Supplement; provided, however, that the Indenture Trustee shall not be responsible for the accuracy or content of any such resolution, certificate, statement, opinion, report, document, order or other instrument furnished pursuant to this Indenture and any applicable Supplement.

No provision of this Indenture or any Supplement shall be construed to relieve the Indenture Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that:

(i) Prior to the occurrence of an Event of Default and after the curing of any Event of Default which may have occurred, the duties and obligations of the Indenture Trustee shall be determined solely by the express provisions of this Indenture and any Supplements issued pursuant to the terms hereof. The Indenture Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and any Supplements issued pursuant to the terms hereof, and no implied covenants or obligations shall be read into this Indenture against the Indenture Trustee and, in the absence of bad faith on the part of the Indenture Trustee, the Indenture Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any Opinion of Counsel, certificates, statements, reports, documents, orders, opinions, appraisals, bonds or other documents or instruments believed by it to be genuine and to have been signed or presented by the proper party or parties and conforming to the requirements of this Indenture and any Supplements issued pursuant to the terms hereof;

(ii) The Indenture Trustee shall not be liable for an error of judgment made in good faith by a Corporate Trust Officer or Corporate Trust Officers of the Indenture Trustee, unless it shall be proved that the Indenture Trustee was negligent in ascertaining the pertinent facts; and

(iii) The Indenture Trustee shall not be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the Control Party of a Series relating to the time, method and place of conducting any Proceeding for any remedy available to the Indenture Trustee, or exercising any trust or power conferred upon the Indenture Trustee, under this Indenture.

No provisions of this Indenture shall require the Indenture Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate security or indemnity against such risk or liability is not reasonably assured to it (the unsecured indemnity of (A) a Rated Institutional Noteholder being deemed satisfactory for such purpose unless the Indenture Trustee provides written notice to the contrary, or (B) any Series Enhancer, if applicable (so long as its claims

paying ability is rated “AAA” or “Aaa”, as applicable) being deemed satisfactory for such purpose).

Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Indenture Trustee shall be subject to the provisions of this Section 901.

Section 902. Certain Matters Affecting the Indenture Trustee. Except as otherwise provided in Section 901 hereof:

(i) The Indenture Trustee may consult with counsel of its selection and any advice of such counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance in reliance thereof;

(ii) The Indenture Trustee shall be under no obligation to institute, conduct or defend any litigation or proceeding hereunder or in relation hereto at the request, order or direction of the Control Party of a Series, pursuant to the provisions of this Indenture, unless the such Control Party shall have offered to the Indenture Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby (the unsecured indemnity of (A) a Rated Institutional Noteholder being deemed satisfactory for such purpose, unless the Indenture Trustee provides written notice to the contrary or (B) any Series Enhancer if applicable (so long as its claims paying ability is rated “AAA” or “Aaa”, as applicable) being deemed satisfactory for such purpose);

(iii) The Indenture Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture;

(iv) The Indenture 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, consent, order, approval, bond or other paper or document, unless requested in writing to do so by the Control Party of a Series; provided, however, that the Indenture Trustee may require reasonable security or indemnity against any cost, expense or liability likely to be incurred in making such investigation as a condition to so proceeding (the unsecured indemnity of (A) a Rated Institutional Noteholder being deemed satisfactory for such purposes unless the Indenture Trustee provides written notice to the contrary) or (B) any Series Enhancer (so long as its claims paying ability is rated “AAA” or “Aaa,” as applicable) being deemed satisfactory for such purpose). The reasonable expense of any such examination shall be paid, on a pro rata basis, by the Noteholders of the applicable Series requesting such examination or, if paid by the Indenture Trustee, shall be reimbursed by such Noteholders upon demand;

(v) The Indenture Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through its agents or attorneys, provided that the Indenture Trustee shall not be responsible for any misconduct or

negligence on the part of any agent or attorney appointed by it with due care hereunder; and

(vi) The Indenture Trustee shall not be charged with knowledge of any Default or Event of Default unless either a Corporate Trust Officer of the Indenture Trustee shall have actual knowledge or written notice of such shall have been given to a Corporate Trust Officer of the Indenture Trustee.

The Indenture 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 pursuant to this Indenture, unless such Holders shall have offered to the Indenture Trustee security or indemnity satisfactory to the Indenture Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. The rights, privileges, protections, immunities and benefits given to the Indenture Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Indenture Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder. The Indenture Trustee may request that the Issuer deliver an Officer’s Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any person authorized to sign an Officer’s Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

The provisions of this Section 902 shall be applicable to the Indenture Trustee in its capacity as Indenture Trustee under this Indenture.

Section 903. Indenture Trustee Not Liable. The recitals contained herein (other than the representations and warranties contained in Section 911 hereof), in any Supplement and in the Notes (other than the certificate of authentication on the Notes) shall be taken as the statements of the Issuer, and the Indenture Trustee assumes no responsibility for their correctness. The Indenture Trustee makes no representations as to the validity or sufficiency of this Indenture, any Supplement, the Notes, the Collateral or of any related document. The Indenture Trustee shall not be accountable for the use or application by the Issuer of any of the Notes or of the proceeds thereof, or for the use or application of any funds paid to the Issuer or the Servicer in respect of the Collateral. The Indenture Trustee will be deemed to have appointed Barclays Bank PLC to act as Administrative Agent under the terms of the Administration Agreement without negligence or willful misconduct.

(a) The Indenture Trustee shall have no responsibility or liability for or with respect to the existence or validity of any Engine, the perfection of any security interest (whether as of the date hereof or at any future time), the maintenance of or the taking of any action to maintain such perfection, the validity of the assignment of any portion of the Collateral to the Indenture Trustee or of any intervening assignment, the compliance by the Seller or the Servicer with any covenant or the breach by the Seller or the Servicer of any warranty or representation made hereunder, in any Supplement or in any related document or the accuracy of such warranty or representation, any investment of monies in the Trust Account, the Restricted Cash Account or any Series Account or any loss resulting therefrom (provided that such investments are made in accordance with the provisions of Section 303 hereof), the acts or omissions of the Seller or

the Servicer taken in the name of the Indenture Trustee, or the acts or omissions of the Administrative Agent.

(b) Except as expressly provided herein or in any Supplement, the Indenture Trustee shall not have any obligation or liability under any Contract by reason of or arising out of this Indenture or the granting of a security interest in such Contract hereunder or the receipt by the Indenture Trustee of any payment relating to any Contract pursuant hereto, nor shall the Indenture Trustee be required or obligated in any manner to perform or fulfill any of the obligations of the Issuer, the Seller or the Servicer under or pursuant to any Contract, or to make any payment, or to make any inquiry as to the nature or the sufficiency of any payment received by it, or the sufficiency of any performance by any party, under any Contract.

Section 904. Indenture Trustee May Own Notes. The Indenture Trustee in its individual or any other capacity may become the owner or pledgee of Notes with the same rights it would have if it were not Indenture Trustee; provided that such transaction shall not result in the disqualification of the Indenture Trustee for purposes of Rule 3a-7 under the Investment Company Act of 1940.

Section 905. Indenture Trustee’s Fees and Expenses. The fees of the Indenture Trustee shall be paid by the Issuer in accordance with Section 3.02 of a related Supplement for a Series. The Issuer shall indemnify the Indenture Trustee and each of its officers, directors and employees for, and hold them harmless against, any loss, liability, damage, claim or expense incurred without negligence or willful misconduct on their part, arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself both individually and in its representative capacity against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder (including, but not limited to, loss, liability, damage, claim or expense incurred by reason of the appointment of Barclays Bank PLC to act as Administrative Agent).

The obligations of the Issuer under this Section 905 to compensate the Indenture Trustee, to pay or reimburse the Indenture Trustee for expenses, disbursements and advances and to indemnify and hold harmless the Indenture Trustee shall constitute Outstanding Obligations hereunder and shall survive the resignation or removal of the Indenture Trustee and the satisfaction and discharge of this Indenture.

When the Indenture Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 801(iii) or Section 801(iv), the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy law.

Anything in this Indenture to the contrary notwithstanding, in no event shall the Indenture Trustee be liable under or in connection with this Indenture for indirect, special, incidental, punitive or consequential losses or damages of any kind whatsoever, including but not limited to lost profits, whether or not foreseeable, even if the Indenture Trustee has been advised of the possibility thereof and regardless of the form of action in which such damages are sought.

Section 906. Eligibility Requirements for Indenture Trustee. The Indenture Trustee hereunder shall at all times be a national banking association or a corporation, organized and doing business under the laws of the United States of America or any State, and authorized under such laws to exercise corporate trust powers. In addition, the Indenture Trustee or its parent corporation shall at all times (i) have a combined capital and surplus of at least $250,000,000, (ii) be subject to supervision or examination by Federal or state authority and (iii) have a long-term unsecured senior debt rating of “A2” or better by Moody’s or a long-term unsecured senior debt rating of “A” by Standard & Poor’s and short-term unsecured senior debt rating of “P-1” or better by Moody’s or a short-term unsecured senior debt rating of “A-2” by Standard & Poor’s. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of such supervising or examining authority, then, for the purposes of this Section 906, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Indenture Trustee shall cease to be eligible in accordance with the provisions of this Section 906, the Indenture Trustee shall resign immediately in the manner and with the effect specified in Section 907 hereof. In lieu of the foregoing eligibility requirements for the Indenture Trustee, The Bank of New York shall be an eligible Indenture Trustee.

Section 907. Resignation and Removal of Indenture Trustee. The Indenture Trustee may at any time resign and be discharged from the trusts hereby created by giving written notice thereof to the Issuer, the Servicer, the Administrative Agent, each Series Enhancer if applicable and the Noteholders. Upon receiving such notice of resignation, the Issuer shall promptly appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning Indenture Trustee and each Series Enhancer if applicable, and one copy to the successor Indenture Trustee. If no successor Indenture Trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the Requisite Global Majority may appoint a successor trustee or, if it does not do so within 30 days thereafter, the resigning Indenture Trustee, with the consent of each Series Enhancer, may petition any court of competent jurisdiction for the appointment of a successor trustee, which successor trustee shall meet the eligibility standards set forth in Section 906.

If at any time the Indenture Trustee shall cease to be eligible in accordance with the provisions of Section 906 hereof and shall fail to resign after written request therefor by the Issuer, any Series Enhancer if applicable or the Servicer, or if at any time the Indenture Trustee shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Indenture Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Indenture Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Issuer shall remove the Indenture Trustee and appoint a successor Indenture Trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the Indenture Trustee so removed and one copy to the successor Indenture Trustee.

Any resignation or removal of the Indenture Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section shall become effective upon acceptance of appointment by the successor trustee as provided in Section 908 hereof.

Section 908. Successor Indenture Trustee. Any successor Indenture Trustee appointed as provided in Section 907 hereof shall execute, acknowledge and deliver to the Issuer and to its predecessor Indenture Trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Indenture Trustee shall become effective and such successor Indenture Trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as the Indenture Trustee herein. The predecessor Indenture Trustee shall deliver to the successor Indenture Trustee all documents relating to the Collateral, if any, delivered to it, together with any amount remaining in the Trust Account, Restricted Cash Account and any other Series Accounts. In addition, the predecessor Indenture Trustee and, upon request of the successor Indenture Trustee, the Issuer shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor Indenture Trustee all such rights, powers, duties and obligations.

No successor Indenture Trustee shall accept appointment as provided in this Section 908 unless at the time of such acceptance such successor Indenture Trustee shall be eligible under the provisions of Section 906 hereof and shall be acceptable to the Requisite Global Majority.

Upon acceptance of appointment by a successor Indenture Trustee as provided in this Section 908, the Issuer shall mail notice of the succession of such Indenture Trustee hereunder to all Noteholders at their addresses as shown in the registration books maintained by the Indenture Trustee. If the Issuer fails to mail such notice within 10 days after acceptance of appointment by the successor Indenture Trustee, the successor Indenture Trustee shall cause such notice to be mailed at the expense of the Issuer.

Section 909. Merger or Consolidation of Indenture Trustee. Any corporation into which the Indenture Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Indenture Trustee shall be a party, or any corporation succeeding to the business of the Indenture Trustee, shall be the successor of the Indenture Trustee hereunder, provided such corporation shall be eligible under the provisions of Section 906 hereof, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 910. Separate Indenture Trustees, Co-Indenture Trustees and Custodians. If the Indenture Trustee is not capable of acting outside the United States of America, it shall have the power from time to time to appoint one or more Persons or corporations to act either as co-trustees jointly with the Indenture Trustee, or as separate trustees, or as custodians, for the purpose of holding title to, foreclosing or otherwise taking action with respect to any of the Collateral, when such separate trustee or co-trustee is necessary or advisable under any applicable laws or for the purpose of otherwise conforming to any legal requirement, restriction or condition in any applicable jurisdiction. The separate trustees, co-trustees, or custodians so appointed shall be trustees, co-trustees, or custodians for the benefit of all Noteholders and shall have such powers, rights and remedies as shall be specified in the instrument of appointment; provided, however, that no such appointment shall, or shall be deemed to, constitute the

appointee an agent of the Indenture Trustee. The Issuer shall join in any such appointment, but such joining shall not be necessary for the effectiveness of such appointment.

Every separate trustee, co-trustee and custodian shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i) all powers, duties, obligations and rights conferred upon the Indenture Trustee in respect of the receipt, custody and payment of moneys shall be exercised solely by the Indenture Trustee;

(ii) all other rights, powers, duties and obligations conferred or imposed upon the Indenture Trustee shall be conferred or imposed upon and exercised or performed by the Indenture Trustee and such separate trustee, co-trustee, or custodian jointly, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed the Indenture Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Collateral or any portion thereof in any such jurisdiction) shall be exercised and performed by such separate trustee, co-trustee or custodian;

(iii) no trustee or custodian hereunder shall be personally liable by reason of any act or omission of any other trustee or custodian hereunder; and

(iv) the Issuer or the Indenture Trustee may at any time accept the resignation of or remove any separate trustee, co-trustee or custodian so appointed by it or them if such resignation or removal does not violate the other terms of this Indenture.

Any notice, request or other writing given to the Indenture Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee, co-trustee, or custodian shall refer to this Indenture and the conditions of this Article. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Indenture Trustee or separately, as may be provided therein, subject to all the provisions of this Indenture, specifically including every provision of this Indenture relating to the conduct of, affecting the liability of, or affording protection to, the Indenture Trustee. Every such instrument of appointment shall be furnished to the Indenture Trustee and each Series Enhancer.

Any separate trustee, co-trustees, or custodian may, at any time, constitute the Indenture Trustee, its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Indenture on its behalf and in its name. If any separate trustee, co-trustee, or custodian shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Indenture Trustee, to the extent permitted by law, without the appointment of a new or successor trustee or custodian.

No separate trustee, co-trustee or custodian hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 906 hereof and no notice to Noteholders of the appointment thereof shall be required under Section 908 hereof.

The Indenture Trustee agrees to instruct the co-trustees, if any, to the extent necessary to fulfill the Indenture Trustee’s obligations hereunder.

(c) Binding Obligations. This Indenture and each Supplement, assuming due authorization, execution and delivery by the Issuer, constitutes the legal, valid and binding obligations of the Indenture Trustee, enforceable against the Indenture Trustee in accordance with its terms, except that (i) such enforcement may be subject to bankruptcy, insolvency, reorganization, moratorium or other similar laws (whether statutory, regulatory or decisional) now or hereafter in effect relating to creditors’ rights generally and the rights of trust companies in particular and (ii) the remedy of specific performance and injunctive and other forms of equitable relief may be subject to certain equitable defenses and to the discretion of the court before which any proceeding therefor may be brought, whether in a proceeding at law or in equity;

(e) No Proceedings. There are no proceedings or investigations to which the Indenture Trustee is a party pending, or, to the knowledge of the Indenture Trustee, threatened, before any court, regulatory body, administrative agency or other tribunal or Governmental Authority (A) asserting the invalidity of this Indenture or the Notes, (B) seeking to prevent the issuance of the Notes or the consummation of any of the transactions contemplated by this Indenture or (C) seeking any determination or ruling that would materially and adversely affect the performance by the Indenture Trustee of its obligations under, or the validity or enforceability of, this Indenture or the Notes; and

(f) Approvals. Neither the execution or delivery by the Indenture Trustee of this Indenture nor the consummation of the transactions by the Indenture Trustee contemplated hereby requires the consent or approval of, the giving of notice to, the registration with or the taking of any other action with respect to any Governmental Authority under any existing federal or State of New York law governing the banking or trust powers of the Indenture Trustee.

(g) Securities Accounts. (i) The Indenture Trustee is a bank which regularly accepts in the ordinary course of its business securities of the same type as the applicable Collateral as a custodial service for its customers and maintains in the State of New York deposit accounts and securities accounts for its customers; (ii) the Indenture Trustee will at all times be acting solely in the capacity of a Securities Intermediary with respect to items of Collateral identified on its books and records; (iii) the Indenture Trustee will maintain its offices and books and records with respect to its securities accounts in the State of New York; (iv) the Indenture Trustee will at all times maintain an account with and be a member of The Federal Reserve Bank; and (v) the Indenture Trustee will act in accordance with, and fulfill its obligations under the terms of this Indenture and any Supplement hereto, on its part to be performed or observed, including, without limitation, crediting each Financial Asset (as defined in Section 8-102(a)(9) of the New York UCC) and any other property it receives in accordance thereunder to the appropriate Securities Account.

Section 914. Assignment of Rights, Not Assumption of Duties. Anything herein contained to the contrary notwithstanding, (a) the Issuer shall remain liable under each of the agreements to which it is a party to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Indenture had not been executed, (b) the exercise by the Indenture Trustee or the Noteholders of any of their rights, remedies or powers hereunder shall not release the Issuer from any of its duties or obligations under each of the agreements to which it is a party and (c) neither the Noteholders nor the Indenture Trustee shall have any obligation or liability under any of the agreements to which the Issuer is a party by reason of or arising out of this Indenture, nor shall the Noteholders or the Indenture Trustee be obligated to perform any of the obligations or duties of the Issuer thereunder or, except as expressly provided herein with respect to the Indenture Trustee, to take any action to collect or enforce any claim for payment assigned hereunder or otherwise or except as expressly provided in the applicable Note Purchase Agreement with respect to the Noteholders.
