It is expressly agreed that anything herein contained to the contrary notwithstanding, the Owner Trustee shall remain liable under the Indenture Agreements, to perform all of the obligations assumed by it thereunder, except to the extent prohibited or excluded from doing so pursuant to the terms and provisions thereof, and the Mortgagee, the Loan Participants, the Note Holders and the Indenture Indemnitees shall have no obligation or liability under the Indenture Agreements, by reason of or arising out of the assignment hereunder, nor shall the Mortgagee, the Loan Participants, the Note Holders or the Indenture Indemnitees be required or obligated in any manner to perform or fulfill any obligations of the Owner Trustee under or pursuant to the Indenture Agreements, or, except as herein expressly provided, to make any payment, or to make any inquiry as to the nature or sufficiency of any payment received by it, or present or file any claim, or take any action to collect or enforce the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

Without limiting the generality of the foregoing, but subject to the rights of the Owner Trustee and the Owner Participant under Sections 2.13, 4.03 and 4.04(a) hereof, during the continuance of any Event of Default under this Trust Indenture, the Mortgagee shall have the right under such power of attorney to accept any offer in connection with the exercise of remedies as set forth herein of any purchaser to purchase the Airframe and Engines and upon such purchase to execute and deliver in the name of and on behalf of the Owner Trustee an appropriate ▇▇▇▇ of sale and other instruments of transfer relating to the Airframe and Engines, when purchased by such purchaser, and to perform all other necessary or appropriate acts with respect to any such purchase, and in its discretion to file any claim or take any other action or proceedings, either in its own name or in the name of the Owner Trustee or otherwise, which the Mortgagee may deem necessary or appropriate to protect and preserve the right, title and interest of the Mortgagee in and to such Rents and other sums and the security intended to be afforded hereby; provided, however, that no action of the Mortgagee pursuant to this paragraph shall increase the obligations or liabilities of the Owner Trustee to any Person beyond those obligations and liabilities specifically set forth in this Trust Indenture and in the other Operative Agreements. Under the Lease, Lessee is directed, so long as this Trust Indenture shall not have been fully discharged, to make all payments of Rent (other than Excluded Payments) and all other amounts which are required to be paid to or deposited with the Owner Trustee pursuant to the Lease (other than Excluded Payments) directly to, or as directed by, the Mortgagee at such address or addresses as the Mortgagee shall specify, for application as provided in this Trust Indenture. The Owner Trustee agrees that promptly upon receipt thereof, it will transfer to the Mortgagee any and all monies from time to time received by it constituting part of the Trust Indenture Estate, for distribution by the Mortgagee pursuant to this Trust Indenture, except that the Owner Trustee shall accept for distribution pursuant to the Trust Agreement any amounts distributed to it by the Mortgagee under this Trust Indenture.

The Owner Trustee agrees that at any time and from time to time, upon the written request of the Mortgagee, the Owner Trustee will promptly and duly execute and deliver or cause to be duly executed and delivered any and all such further instruments and documents as the Mortgagee may reasonably deem necessary or desirable to perfect, preserve or protect the mortgage, security interests and assignments created or intended to be created hereby or to obtain for the Mortgagee the full benefits of the assignment hereunder and of the rights and powers herein granted.

The Owner Trustee does hereby warrant and represent that it has not assigned or pledged, and hereby covenants and agrees that it will not assign or pledge, so long as the assignment hereunder shall remain in effect, and the Lien hereof shall not have been released pursuant to Section 10.01 hereof, any of its right, title or interest hereby assigned, to anyone other than the Mortgagee, and that it will not, except as otherwise provided in this Trust Indenture and except with respect to Excluded Payments to which it is entitled, (i) accept any payment from Lessee or any Permitted Sublessee under any Indenture Agreement, (ii) enter into any agreement amending or supplementing any Indenture Agreement, (iii) execute any waiver or modification of, or consent under, the terms of, or exercise any rights, powers or privileges under, any Indenture Agreement, (iv) settle or compromise any claim arising under any Indenture Agreement or (v) submit or consent to the submission of any dispute, difference or other matter arising under or in respect of any Indenture Agreement to arbitration thereunder.

The Owner Trustee does hereby agree that it will not without the written consent of the Mortgagee:

(a) receive or collect or agree to the receipt or collection of any payment (other than Excluded Payments) of Rent, including Basic Rent, Stipulated Loss Value, Termination Value or any other payment to be made pursuant to Section 9 or 10 of the Lease prior to the date for the payment thereof provided for by the Lease or assign, transfer or hypothecate (other than to the Mortgagee hereunder) any payment of Rent, including Basic Rent, Stipulated Loss Value, Termination Value or any other payment to be made pursuant to Section 9 or 10 of the Lease, then due or to accrue in the future under the Lease in respect of the Airframe and Engines; or

(b) except as contemplated by the Trust Agreement in connection with the appointment of a successor owner trustee, sell, mortgage, transfer, assign or hypothecate (other than to the Mortgagee hereunder) its interest in the Airframe and Engines or any part thereof or in any amount to be received by it from the use or disposition of the Airframe and Engines, other than amounts distributed to it pursuant to Article III hereof.

It is hereby further agreed that any and all property described or referred to in the granting clauses hereof which is hereafter acquired by the Owner Trustee shall ipso facto, and without any other conveyance, assignment or act on the part of the Owner Trustee or the Mortgagee, become and be subject to the Lien herein granted as fully and completely as though specifically described herein, but nothing contained in this paragraph shall be deemed to modify or change the obligations of the Owner Trustee contained in the foregoing paragraphs.

The Owner Trustee does hereby ratify and confirm the Lease and does hereby agree that it will not violate any covenant or agreement made by it therein, herein or in any other Owner Trustee Agreement.

Notwithstanding the Granting Clause or any of the preceding paragraphs, there is hereby excluded from the foregoing sale, transfer, assignment, grant, pledge and security interest all Excluded Payments. Further, nothing in the Granting Clause or the preceding paragraphs shall impair any of the rights of the Owner Trustee or the Owner Participant under Section 2.13, 4.03, 4.04, 4.08, 5.02 or 5.03 hereof.

IT IS HEREBY COVENANTED AND AGREED by and between the parties hereto as follows:

FIRST SECURITY BANK, NATIONAL ASSOCIATION, not in its individual capacity but solely as Owner Trustee (herein in such capacity called the “Owner Trustee”) under that certain Trust Agreement 645, dated as of September 30, 1997, between the Owner Participant named therein and First Security Bank, National Association (herein as such Trust Agreement may be supplemented or amended from time to time called the “Trust Agreement”), hereby promises to pay to __________________, or the registered assignee thereof, the principal sum of $____________ (the “Original Amount”), together with interest on the amount of the Original Amount remaining unpaid from time to time (calculated on the basis of a year of 360 days comprised of twelve 30-day months) from the date hereof until paid in full at a rate per annum equal to the Debt Rate. The Original Amount of this Equipment Note shall be payable in installments on the dates set forth in Schedule I hereto equal to the corresponding percentage of the Original Amount of this Equipment Note set forth in Schedule I hereto. Accrued but unpaid interest shall be due and payable in semiannual installments commencing on October 1, 1997, and thereafter on April 1 and October 1 of each year, to and including _______________. Notwithstanding the foregoing, the final payment made on this Equipment Note shall be in an amount sufficient to discharge in full the unpaid Original Amount and all accrued and unpaid interest on, and any other amounts due under, this Equipment Note. Notwithstanding anything to the contrary contained herein, if any date on which a payment under this Equipment Note becomes due and payable is not a Business Day, then such payment shall not be made on such scheduled date but shall be made on the next succeeding Business Day and if such payment is made on such next succeeding Business Day, no interest shall accrue on the amount of such payment during such extension.

For purposes hereof, the term “Trust Indenture” means the Trust Indenture and Mortgage 645, dated as of September 30, 1997, between the Owner Trustee and Wilmington Trust Company (the “Mortgagee”), as the same may be amended or supplemented from time to time. All other capitalized terms used in this Equipment Note and not defined herein shall have the respective meanings assigned in the Trust Indenture.

This Equipment Note shall bear interest, payable on demand, at the Payment Due Rate (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any overdue Original Amount, any overdue Make-Whole Amount, if any, and (to the extent permitted by applicable Law) any overdue interest and any other amounts payable hereunder which are overdue, in each case for the period the same is overdue. Amounts shall be overdue if not paid when due (whether at stated maturity, by acceleration or otherwise).

The interest rate borne by this Equipment Note shall be subject to adjustments to the extent, and under the circumstances, specified by the Registration Rights Agreement.

All payments of Original Amount, interest, Make-Whole Amount, if any, and other amounts, if any, to be made by the Owner Trustee hereunder and under the Trust Indenture or the Participation Agreement shall be payable only from the income and proceeds from the Trust Estate to the extent included in the Trust Indenture Estate and only to the extent that the Owner Trustee shall have sufficient income or proceeds from the Trust Estate to the extent included in the Trust Indenture Estate to enable the Mortgagee to make such payments in accordance with the terms of Section 2.03 and Article III of the Trust Indenture, and each holder hereof, by its acceptance of this Equipment Note, agrees that it will look solely to the income and proceeds from the Trust Indenture Estate to the extent available for distribution to the holder hereof as above provided and that none of the Owner Participant, the Owner Trustee and the Mortgagee is personally liable or liable in any manner extending to any assets other than the Trust Indenture Estate to the holder hereof for any amounts payable or any liability under this Equipment Note or, except as provided in the Trust Indenture or in the Participation Agreement, for any liability under the Trust Indenture or the Participation Agreement; provided, however, that nothing herein contained shall limit, restrict or impair the right of the Mortgagee, subject always to the terms and provisions of the Trust Indenture, to accelerate the maturity of this Equipment Note upon occurrence of an Event of Default under the Trust Indenture in accordance with Section 4.04(b) of the Trust Indenture, to bring suit and obtain a judgment against the Owner Trustee on this Equipment Note for purposes of realizing upon the Trust Indenture Estate and to exercise all rights and remedies provided under the Trust Indenture or otherwise realize upon the Trust Indenture Estate as provided under the Trust Indenture.

There shall be maintained an Equipment Note Register for the purpose of registering transfers and exchanges of Equipment Notes at the Corporate Trust Office of the Mortgagee or at the office of any successor in the manner provided in Section 2.07 of the Trust Indenture.

The Original Amount and interest and other amounts due hereunder shall be payable in Dollars in immediately available funds at the Corporate Trust Office of the Mortgagee, or as otherwise provided in the Trust Indenture. Each such payment shall be made on the date such payment is due and without any presentment or surrender of this Equipment Note, except that in the case of any final payment with respect to this Equipment Note, the Equipment Note shall be surrendered promptly thereafter to the Mortgagee for cancellation.

The holder hereof, by its acceptance of this Equipment Note, agrees that, except as provided in the Trust Indenture, each payment of the Original Amount, Make-Whole Amount, if any, and interest received by it hereunder shall be applied, first, to the payment of accrued interest on this Equipment Note (as well as any interest on any overdue Original Amount, any overdue Make-Whole Amount, if any, or, to the extent permitted by Law, any overdue interest and other amounts hereunder) to the date of such payment, second, to the payment of the Original Amount of this Equipment Note then due, third, to the payment of Make-Whole Amount, if any, and any other amount due hereunder or under the Trust Indenture, and fourth, the balance, if any, remaining thereafter, to the payment of installments of the Original Amount of this Equipment Note remaining unpaid in the inverse order of their maturity.

This Equipment Note is one of the Equipment Notes referred to in the Trust Indenture which have been or are to be issued by the Owner Trustee pursuant to the terms of the Trust Indenture. The Trust Indenture Estate is held by the Mortgagee as security, in part, for the Equipment Notes. The provisions of this Equipment Note are subject to the Trust Indenture. Reference is hereby made to the Trust Indenture for a complete statement of the rights and obligations of the holder of, and the nature and extent of the security for, this Equipment Note and the rights and obligations of the holders of, and the nature and extent of the security for, any other Equipment Notes executed and delivered under the Trust Indenture, as well as for a statement of the terms and conditions of the Trust created by the Trust Indenture, to all of which terms and conditions in the Trust Indenture each holder hereof agrees by its acceptance of this Equipment Note.

SECTION 2.02. Issuance and Terms of Equipment Notes

The Equipment Notes shall be dated the date of issuance thereof, shall be issued in three separate series consisting of Series A, Series B and Series C and in the maturities and principal amounts and shall bear interest as specified in Schedule I hereto. On the date of the consummation of the Transactions, each Equipment Note shall be issued to the Subordination Agent on behalf of the Pass Through Trustees under the Pass Through Trust Agreements. The Equipment Notes shall be issued in registered form only. The Equipment Notes shall be issued in denominations of $1,000 and integral multiples thereof, except that one Equipment Note of each Series may be in an amount that is not an integral multiple of $1,000.

Each Equipment Note shall bear interest at the Debt Rate (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on the unpaid Original Amount thereof from time to time outstanding, payable in arrears on October 1, 1997, and on each April 1 and October 1 thereafter until maturity. The Original Amount of each Equipment Note shall be payable on the dates and in the installments equal to the corresponding percentage of the Original Amount as set forth in Schedule I hereto which shall be attached as Schedule I to the Equipment Notes. Notwithstanding the foregoing, the final payment made under each Equipment Note shall be in an amount sufficient to discharge in full the unpaid Original Amount and all accrued and unpaid interest on, and any other amounts due under, such Equipment Note. Each Equipment Note shall bear interest at the Payment Due Rate (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any part of the Original Amount, Make-Whole Amount, if any, and, to the extent permitted by applicable Law, interest and any other amounts payable thereunder not paid when due for any period during which the same shall be overdue, in each case for the period the same is overdue. Amounts shall be overdue if not paid when due (whether at stated maturity, by acceleration or otherwise). Notwithstanding anything to the contrary contained herein, if any date on which a payment under any Equipment Note becomes due and payable is not a Business Day then such payment shall not be made on such scheduled date but shall be made on the next succeeding Business Day and if such payment is made on such next succeeding Business Day, no interest shall accrue on the amount of such payment during such extension.

The Owner Trustee agrees to pay to the Mortgagee for distribution in accordance with Section 3.04 hereof: (i) to the extent not payable (whether or not in fact paid) under Section 6(a) of the Note Purchase Agreement (as originally in effect or amended with the consent of the Owner Participant), an amount equal to the fees payable to the relevant Liquidity Provider under Section 2.03 of each Liquidity Facility and the related Fee Letter (as defined in the Intercreditor Agreement) multiplied by a fraction the numerator of which shall be the then outstanding aggregate principal amount of the Series A Equipment Notes, Series B Equipment Notes and Series C Equipment Notes and the denominator of which shall be the then outstanding aggregate principal amount of all “Series A Equipment Notes”, “Series B Equipment Notes” and “Series C Equipment Notes” (each as defined in the Note Purchase Agreement); (ii) (x) the amount equal to interest on any Downgrade Advance (other than any Applied Downgrade Advance) payable under Section 3.07(e) of each Liquidity Facility minus Investment Earnings from such Downgrade Advance multiplied by (y) the fraction specified in the foregoing clause (i); (iii) (x) the amount equal to interest on any Non-Extension Advance (other than any Applied Non-Extension Advance) payable under Section 3.07(a)(i) of each Liquidity Facility minus Investment Earnings from such Non-Extension Advance multiplied by (y) the fraction specified in the foregoing clause (i); and (iv) if any payment default shall have occurred and be continuing with respect to interest on any Series A Equipment Note, Series B Equipment Note or Series C Equipment Note, (x) the excess, if any, of (1) the amount equal to interest on any Unpaid Advance, Applied Downgrade Advance or Applied Non-Extension Advance payable under Section 3.07(a)(i) of each Liquidity Facility over (2) the sum of Investment Earnings from any Final Advance plus any amount of interest at the Payment Due Rate actually payable (whether or not in fact paid) by the Owner Trustee on the overdue scheduled interest on the Equipment Notes in respect of which such Unpaid Advance, Applied Downgrade Advance or Applied Non-Extension Advance was made multiplied by (y) a fraction the numerator of which shall be the then aggregate overdue amounts of interest on the Series A Equipment Notes, Series B Equipment Notes and Series C Equipment Notes (other than interest becoming due and payable solely as a result of acceleration of any such Equipment Notes) and the denominator of which shall be the then aggregate overdue amounts of interest on all “Series A Equipment Notes”, “Series B Equipment Notes” and “Series C Equipment Notes” (each as defined in the Note Purchase Agreement) (other than interest becoming due and payable solely as a result of acceleration of any such “Equipment Notes”). For purposes of this paragraph, the terms “Applied Downgrade Advance”, “Applied Non-Extension Advance”, “Cash Collateral Account”, “Downgrade Advance”, “Final Advance”, “Investment Earnings”, “Non-Extension Advance” and “Unpaid Advance” shall have the meanings specified in each Liquidity Facility or the Intercreditor Agreement referred to therein.

The Equipment Notes shall be executed on behalf of the Owner Trustee by its President or one of its Vice Presidents, Assistant Vice Presidents or Assistant Secretaries or other authorized officer. Equipment Notes bearing the signatures of individuals who were at any time the proper officers of the Owner Trustee shall bind the Owner Trustee, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Equipment Notes or did not hold such offices at the respective dates of such Equipment Notes. The Owner Trustee may from time to time execute and deliver Equipment Notes with respect to the Aircraft to the Mortgagee for authentication upon original issue and such Equipment Notes shall thereupon be authenticated and delivered by the Mortgagee upon the written request of the Owner Trustee signed by a Vice President or Assistant Vice President or other authorized officer of the Owner Trustee; provided, however, that each such request shall specify the aggregate Original Amount of all Equipment Notes to be authenticated hereunder on original issue with respect to the Aircraft. No Equipment Note shall be secured by or entitled to any benefit under this Trust Indenture or be valid or obligatory for any purposes, unless there appears on such Equipment Note a certificate of authentication in the form provided for herein executed by the Mortgagee by the manual signature of one of its authorized officers and such certificate upon any Equipment Notes be conclusive evidence, and the only evidence, that such Equipment Note has been duly authenticated and delivered hereunder.

The aggregate Original Amount of the Equipment Notes issued hereunder shall not exceed [80]% of Lessor’s Cost.

SECTION 2.03. Payments from Trust Indenture Estate Only

(a) Without impairing any of the other rights, powers, remedies, privileges, liens or security interests of the Note Holders under this Trust Indenture, each Note Holder, by its acceptance of an Equipment Note, agrees that as between it and the Owner Trustee, except as expressly provided in this Trust Indenture, the Participation Agreement or any other Operative Agreement, (i) the obligation to make all payments of the Original Amount of, interest on, Make-Whole Amount, if any, and all other amounts due with respect to the Equipment Notes, and the performance by the Owner Trustee of every obligation or covenant contained in this Trust Indenture and in the Participation Agreement or any of the other Operative Agreements, shall be payable only from the income and proceeds from the Trust Estate to the extent included in the Trust Indenture Estate and only to the extent that the Owner Trustee shall have sufficient income or proceeds from the Trust Estate to the extent included in the Trust Indenture Estate to enable the Mortgagee to make such payments in accordance with the terms of Article III hereof, and all of the statements, representations, covenants and agreements made by the Owner Trustee (when made in such capacity) contained in this Trust Indenture and any agreement referred to herein other than the Trust Agreement, unless expressly otherwise stated, are made and intended only for the purpose of binding the Trust Estate and establishing the existence of rights and remedies which can be exercised and enforced against the Trust Estate; therefore, anything contained in this Trust Indenture or such other agreements to the contrary notwithstanding (except for any express provisions or representations that the Owner Trustee is responsible for, or is making, in its individual capacity, for which there would be personal liability of the Owner Trustee), no recourse shall be had with respect to this Trust Indenture or such other agreements against the Owner Trustee in its individual capacity or against any institution or person which becomes a successor trustee or co-trustee or any officer, director, trustee, servant or direct or indirect parent or controlling Person or Persons of any of them, and (ii) none of the Owner Trustee, in its individual capacity, the Owner Participant, the Mortgagee and any officer, director, trustee, servant, employee, agent or direct or indirect parent or controlling Person or Persons of any of them shall have any personal liability for, and no recourse shall be had against any of them for, any amounts payable hereunder, under the Participation Agreement or any of the other Operative Agreements or under the Equipment Notes except as expressly provided herein, in the Lease or in the Participation Agreement; provided, however, that nothing contained in this Section 2.03(a) shall be construed to limit the exercise and enforcement in accordance with the terms of this Trust Indenture or such other agreements of rights and remedies against the Trust Indenture Estate.

(b) If (i) all or any part of the Trust Estate becomes the property of, or the Owner Trustee or Owner Participant becomes, a debtor subject to the reorganization provisions of the Bankruptcy Code, (ii) pursuant to such reorganization provisions, including Section 1111(b) of the Bankruptcy Code, the Owner Trustee (in its individual capacity) or the Owner Participant is required, by reason of the Owner Trustee (in its individual capacity) or the Owner Participant being held to have recourse liability to any Note Holder or the Mortgagee, directly or indirectly (other than the recourse liability of the Owner Trustee (in its individual capacity) or the Owner Participant under the Participation Agreement, the Lease or this Trust Indenture or by separate agreement), to make payment on account of any amount payable as principal, Make-Whole Amount, if any, interest or other amounts on the Equipment Notes and (iii) any Note Holder or the Mortgagee actually receives any Excess Amount (as hereinafter defined) which reflects any payment by the Owner Trustee (in its individual capacity) or the Owner Participant on account of clause (ii) above, then such Note Holder or the Mortgagee, as the case may be, shall promptly refund to the Owner Trustee (in its individual capacity) or the Owner Participant (whichever shall have made such payment) such Excess Amount.

For purposes of this Section 2.03(b), “Excess Amount” means the amount by which such payment exceeds the amount that would have been received by a Note Holder or the Trustee if the Owner Trustee (in its individual capacity) or the Owner Participant had not become subject to the recourse liability referred to in clause (ii) above. Nothing contained in this Section 2.03(b) shall prevent a Note Holder or the Mortgagee from enforcing any personal recourse obligation (and retaining the proceeds thereof) of the Owner Trustee (in its individual capacity) or the Owner Participant under the Participation Agreement, the Lease or this Trust Indenture (and any exhibits or annexes hereto or thereto) or from retaining any amount paid by Owner Participant under Section 2.13 or 4.03 hereof.

SECTION 2.04. Method of Payment

(a) The Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due under each Equipment Note or hereunder will be payable in Dollars by wire transfer of immediately available funds not later than 12:30 p.m., New York City time, on the due date of payment to the Mortgagee at the Corporate Trust Office for distribution among the Note Holders in the manner provided herein. The Owner Trustee shall not have any responsibility for the distribution of such payment to any Note Holder. Notwithstanding the foregoing or any provision in any Equipment Note to the contrary, the Mortgagee will use reasonable efforts to pay or cause to be paid, if so directed in writing by any Note Holder (with a copy to the Owner Trustee), all amounts paid by the Owner Trustee hereunder and under such holder’s Equipment Note or Equipment Notes to such holder or a nominee therefor (including all amounts distributed pursuant to Article III of this Trust Indenture) by transferring, or causing to be transferred, by wire transfer of immediately available funds in Dollars, prior to 2:00 p.m., New York City time, on the due date of payment, to an account maintained by such holder with a bank located in the continental United States the amount to be distributed to such holder, for credit to the account of such holder maintained at such bank. If the Mortgagee shall fail to make any such payment as provided in the immediately foregoing sentence after its receipt of funds at the place and prior to the time specified above, the Mortgagee, in its individual capacity and not as trustee, agrees to compensate such holders for loss of use of funds at Debt Rate until such payment is made and the Mortgagee shall be entitled to any interest earned on such funds until such payment is made. Any payment made hereunder shall be made without any presentment or surrender of any Equipment Note, except that, in the case of the final payment in respect of any Equipment Note, such Equipment Note shall be surrendered to the Mortgagee for cancellation promptly after such payment. Notwithstanding any other provision of this Trust Indenture to the contrary, the Mortgagee shall not be required to make, or cause to be made, wire transfers as aforesaid prior to the first Business Day on which it is practicable for the Mortgagee to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 12:30 p.m., New York City time, at the place of payment. Prior to the due presentment for registration of transfer of any Equipment Note, the Owner Trustee and the Mortgagee shall deem and treat the Person in whose name any Equipment Note is registered on the Equipment Note Register as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable with respect to such Equipment Note and for all other purposes, and none of the Owner Trustee or the Mortgagee shall be affected by any notice to the contrary. So long as any signatory to the Participation Agreement or nominee thereof shall be a registered Note Holder, all payments to it shall be made to the account of such Note Holder specified in Schedule I thereto and otherwise in the manner provided in or pursuant to the Participation Agreement unless it shall have specified some other account or manner of payment by notice to the Mortgagee consistent with this Section 2.04.

(b) The Mortgagee, as agent for the Owner Trustee, shall exclude and withhold at the appropriate rate from each payment of Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due hereunder or under each Equipment Note (and such exclusion and withholding shall constitute payment in respect of such Equipment Note) any and all United States withholding taxes applicable thereto as required by Law. The Mortgagee agrees to act as such withholding agent and, in connection therewith, whenever any present or future United States taxes or similar charges are required to be withheld with respect to any amounts payable hereunder or in respect of the Equipment Notes, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of the Note Holders, that it will file any necessary United States withholding tax returns or statements when due, and that as promptly as possible after the payment thereof it will deliver to each Note Holder (with a copy to the Owner Trustee and the Lessee) appropriate receipts showing the payment thereof, together with such additional documentary evidence as any such Note Holder may reasonably request from time to time.

If a Note Holder which is a Non-U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form 1001 or W-8 (or such successor form or forms as may be required by the United States Treasury Department) during the calendar year in which the payment hereunder or under the Equipment Note(s) held by such holder is made (but prior to the making of such payment), or in either of the two preceding calendar years, and has not notified the Mortgagee of the withdrawal or inaccuracy of such form prior to the date of such payment (and the Mortgagee has no reason to believe that any information set forth in such form is inaccurate), the Mortgagee shall withhold only the amount, if any, required by Law (after taking into account any applicable exemptions properly claimed by the Note Holder) to be withheld from payments hereunder or under the Equipment Notes held by such holder in respect of United States federal income tax. If a Note Holder (x) which is a Non-U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form 4224 in duplicate (or such successor certificate, form or forms as may be required by the United States Treasury Department as necessary in order to properly avoid withholding of United States federal income tax), for each calendar year in which a payment is made (but prior to the making of any payment for such year), and has not notified the Mortgagee of the withdrawal or inaccuracy of such certificate or form prior to the date of such payment (and the Mortgagee has no reason to believe that any information set forth in such form is inaccurate) or (y) which is a U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W-9, if applicable, prior to a payment hereunder or under the Equipment Notes held by such holder, no amount shall be withheld from payments in respect of United States federal income tax. If any Note Holder has notified the Mortgagee that any of the foregoing forms or certificates is withdrawn or inaccurate, or if such holder has not filed a form claiming an exemption from United States withholding tax or if the Code or the regulations thereunder or the administrative interpretation thereof is at any time after the date hereof amended to require such withholding of United States federal income taxes from payments under the Equipment Notes held by such holder, the Mortgagee agrees to withhold from each payment due to the relevant Note Holder withholding taxes at the appropriate rate under Law and will, on a timely basis as more fully provided above, deposit such amounts with an authorized depository and make such returns, statements, receipts and other documentary evidence in connection therewith as required by Law.

Neither the Owner Trustee nor the Owner Participant shall have any liability for the failure of the Mortgagee to withhold taxes in the manner provided for herein or as required by law, or for any false, inaccurate or untrue evidence provided by any Note Holder hereunder.

SECTION 2.05. Application of Payments

In the case of each Equipment Note, each payment of Original Amount, Make-Whole Amount, if any, and interest due thereon shall be applied:

First: to the payment of accrued interest on such Equipment Note (as well as any interest on any overdue Original Amount, any overdue Make-Whole Amount, if any, and to the extent permitted by Law, any overdue interest and any other overdue amounts thereunder) to the date of such payment;

Second: to the payment of the Original Amount of such Equipment Note (or a portion thereof) then due thereunder;

Third: to the payment of Make-Whole Amount, if any, and any other amount due hereunder or under such Equipment Note; and

Fourth: the balance, if any, remaining thereafter, to the payment of the Original Amount of such Equipment Note remaining unpaid (provided that such Equipment Note shall not be subject to redemption except as provided in Sections 2.10, 2.11 and 2.12 hereof).

The amounts paid pursuant to clause “Fourth” above shall be applied to the installments of Original Amount of such Equipment Note in the inverse order of their normal maturity.

SECTION 2.06. Termination of Interest in Trust Indenture Estate

No Note Holder nor any other Indenture Indemnitee shall, as such, have any further interest in, or other right with respect to, the Trust Indenture Estate when and if the Original Amount of, Make-Whole Amount, if any, and interest on and other amounts due under all Equipment Notes held by such Note Holder and all other sums then due and payable to such Note Holder, such Indenture Indemnitee or the Mortgagee hereunder (including, without limitation, under the third paragraph of Section 2.02 hereof) and under the other Operative Agreements by the Owner Trustee and the Lessee (collectively, the “Secured Obligations”) shall have been paid in full.

SECTION 2.07. Registration Transfer and Exchange of Equipment Notes

The Mortgagee shall keep a register (the “Equipment Note Register”) in which the Mortgagee shall provide for the registration of Equipment Notes and the registration of transfers of Equipment Notes. No such transfer shall be given effect unless and until registration hereunder shall have occurred. The Equipment Note Register shall be kept at the Corporate Trust Office of the Mortgagee. The Mortgagee is hereby appointed “Equipment Note Registrar” for the purpose of registering Equipment Notes and transfers of Equipment Notes as herein provided. A holder of any Equipment Note intending to exchange such Equipment Note shall surrender such Equipment Note to the Mortgagee at the Corporate Trust Office, together with a written request from the registered holder thereof for the issuance of a new Equipment Note, specifying, in the case of a surrender for transfer, the name and address of the new holder or holders. Upon surrender for registration of transfer of any Equipment Note, the Owner Trustee shall execute, and the Mortgagee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Equipment Notes of a like aggregate Original Amount and of the same series. At the option of the Note Holder, Equipment Notes may be exchanged for other Equipment Notes of any authorized denominations of a like aggregate Original Amount, upon surrender of the Equipment Notes to be exchanged to the Mortgagee at the Corporate Trust Office. Whenever any Equipment Notes are so surrendered for exchange, the Owner Trustee shall execute, and the Mortgagee shall authenticate and deliver, the Equipment Notes which the Note Holder making the exchange is entitled to receive. All Equipment Notes issued upon any registration of transfer or exchange of Equipment Notes (whether under this Section 2.07 or under Section 2.08 hereof or otherwise under this Trust Indenture) shall be the valid obligations of the Owner Trustee evidencing the same respective obligations, and entitled to the same security and benefits under this Trust Indenture, as the Equipment Notes surrendered upon such registration of transfer or exchange. Every Equipment Note presented or surrendered for registration of transfer, shall (if so required by the Mortgagee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Mortgagee duly executed by the Note Holder or such holder’s attorney duly authorized in writing, and the Mortgagee shall require evidence satisfactory to it as to the compliance of any such transfer with the Securities Act, and the securities Laws of any applicable state. The Mortgagee shall make a notation on each new Equipment Note of the amount of all payments of Original Amount previously made on the old Equipment Note or Equipment Notes with respect to which such new Equipment Note is issued and the date to which interest on such old Equipment Note or Equipment Notes has been paid. Interest shall be deemed to have been paid on such new Equipment Note to the date on which interest shall have been paid on such old Equipment Note, and all payments of the Original Amount marked on such new Equipment Note, as provided above, shall be deemed to have been made thereon. The Owner Trustee shall not be required to exchange any surrendered Equipment Notes as provided above during the ten-day period preceding the due date of any payment on such Equipment Note. The Owner Trustee shall in all cases deem the Person in whose name any Equipment Note shall have been issued and registered as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable by the Owner Trustee with respect to such Equipment Note and for all purposes until a notice stating otherwise is received from the Mortgagee and such change is reflected on the Equipment Note Register. The Mortgagee will promptly notify the Owner Trustee and the Lessee of each registration of a transfer of an Equipment Note. Any such transferee of an Equipment Note, by its acceptance of an Equipment Note, agrees to the provisions of the Participation Agreement applicable to Note Holders, and shall be deemed to have covenanted to the parties to the Participation Agreement as to the matters covenanted by the original Loan Participant in the Participation Agreement. Subject to compliance by the Note Holder and its transferee (if any) of the requirements set forth in this Section 2.07, Mortgagee and Owner Trustee shall use all reasonable efforts to issue new Equipment Notes upon transfer or exchange within 10 Business Days of the date an Equipment Note is surrendered for transfer or exchange.

SECTION 2.08. Mutilated, Destroyed, Lost or Stolen Equipment Notes

If any Equipment Note shall become mutilated, destroyed, lost or stolen, the Owner Trustee shall, upon the written request of the holder of such Equipment Note, execute and the Mortgagee shall authenticate and deliver in replacement thereof a new Equipment Note, payable in the same Original Amount dated the same date and captioned as issued in connection with the Aircraft. If the Equipment Note being replaced has become mutilated, such Equipment Note shall be surrendered to the Mortgagee and a photocopy thereof shall be furnished to the Owner Trustee. If the Equipment Note being replaced has been destroyed, lost or stolen, the holder of such Equipment Note shall furnish to the Owner Trustee and the Mortgagee such security or indemnity as may be required by them to save the Owner Trustee and the Mortgagee harmless and evidence satisfactory to the Owner Trustee and the Mortgagee of the destruction, loss or theft of such Equipment Note and of the ownership thereof. If a “qualified institutional buyer” of the type referred to in paragraph (a)(1)(i)(A), (B), (D) or (E) of Rule 144A under the Securities Act (a “QIB”) is the holder of any such destroyed, lost or stolen Equipment Note, then the written indemnity of such QIB, signed by an authorized officer thereof, in favor of, delivered to and in form reasonably satisfactory to Lessee, Owner Trustee and Mortgagee shall be accepted as satisfactory indemnity and security and no further indemnity or security shall be required as a condition to the execution and delivery of such new Equipment Note. Subject to compliance by the Note Holder of the requirements set forth in this Section 2.08, Mortgagee and Owner Trustee shall use all reasonable efforts to issue new Equipment Notes within 10 Business Days of the date of the written request therefor from the Note Holder.

SECTION 2.09. Payment of Expenses on Transfer; Cancellation

(a) No service charge shall be made to a Note Holder for any registration of transfer or exchange of Equipment Notes, but the Mortgagee, as Equipment Note Registrar, may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Equipment Notes.

(b) The Mortgagee shall cancel all Equipment Notes surrendered for replacement, redemption, transfer, exchange, payment or cancellation and shall destroy the canceled Equipment Notes.

SECTION 2.10. Mandatory Redemptions of Equipment Notes

(a) On the date on which Lessee is required pursuant to Section 10.1.2 of the Lease to make payment for an Event of Loss with respect to the Aircraft, all of the Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with all accrued interest thereon to the date of redemption and all other Secured Obligations owed or then due and payable to the Note Holders but without Make-Whole Amount.

(b) If the Lease is terminated with respect to the Aircraft by Lessee pursuant to Section 9 thereof, on the date the Lease is so terminated, all the Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with accrued interest thereon to the date of redemption and all other amounts then due and payable hereunder and under the Participation Agreement and all other Operative Agreements to the Note Holders plus, if such redemption is made prior to the Premium Termination Date, Make-Whole Amount, if any.

SECTION 2.11. Voluntary Redemptions of Equipment Notes

All (but not less than all) of the Equipment Notes may be redeemed by the Owner Trustee in connection with a transaction described in, and subject to the terms and conditions of, Section 11 of the Participation Agreement upon at least 30 days’ revocable prior written notice to the Mortgagee and the Note Holders, and the Equipment Notes shall, as provided in Section 11 of the Participation Agreement, be redeemed in whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with accrued interest thereon to the date of redemption and all other Secured Obligations owed or then due and payable to the Note Holders plus (except as provided in Section 11 of the Participation Agreement), if such redemption is made prior to the Premium Termination Date, Make-Whole Amount, if any.

SECTION 2.12. Redemptions; Notice of Redemption

(a) Neither any redemption of any Equipment Note nor any purchase by the Owner Trustee of any Equipment Note may be made except to the extent and in the manner expressly permitted by this Trust Indenture. No purchase of any Equipment Note may be made by the Mortgagee.

(b) Notice of redemption or purchase with respect to the Equipment Notes shall be given by the Mortgagee by first-class mail, postage prepaid, mailed not less than 25 nor more than 60 days prior to the applicable redemption date, to each Note Holder of such Equipment Notes to be redeemed or purchased, at such Note Holder’s address appearing in the Equipment Note Register; provided that, in the case of a redemption to be made pursuant to Section 2.10(b) or Section 2.11, such notice shall be revocable and shall be deemed revoked in the event that the Lease does not in fact terminate on the specified termination date or if notice of such redemption shall have been given in connection with a refinancing of Equipment Notes and the Mortgagee receives written notice of such revocation from the Lessee or the Owner Trustee not later than three days prior to the redemption date. All notices of redemption shall state: (1) the redemption date, (2) the applicable basis for determining the redemption price, (3) that on the redemption date, the redemption price will become due and payable upon each such Equipment Note, and that, if any such Equipment Notes are then outstanding, interest on such Equipment Notes shall cease to accrue on and after such redemption date, and (4) the place or places where such Equipment Notes are to be surrendered for payment of the redemption price.

(c) On or before the redemption date, the Owner Trustee (or any person on behalf of the Owner Trustee) shall, to the extent an amount equal to the redemption price for the Equipment Notes to be redeemed or purchased on the redemption date shall not then be held in the Trust Indenture Estate, deposit or cause to be deposited with the Mortgagee by 12:00 noon on the redemption date in immediately available funds the redemption price of the Equipment Notes to be redeemed or purchased.

(d) Notice of redemption or purchase having been given as aforesaid (and not deemed revoked as contemplated in the proviso to Section 2.12(b)), the Equipment Notes to be redeemed or purchased shall, on the redemption date, become due and payable at the Corporate Trust Office of the Mortgagee or at any office or agency maintained for such purposes pursuant to Section 2.07, and from and after such redemption date (unless there shall be a default in the payment of the redemption price) any such Equipment Notes then outstanding shall cease to bear interest. Upon surrender of any such Equipment Note for redemption or purchase in accordance with said notice, such Equipment Note shall be redeemed at the redemption price. If any Equipment Note called for redemption or purchase shall not be so paid upon surrender thereof for redemption, the principal amount thereof shall, until paid, continue to bear interest from the applicable redemption date at the interest rate in effect for such Equipment Note as of such redemption date.

SECTION 2.13. Option to Purchase Equipment Notes

The Owner Trustee and the Owner Participant may, upon the events and subject to the terms and conditions and for the price set forth in this Section 2.13, purchase all but not less than all of the Equipment Notes outstanding hereunder, and each Note Holder agrees that it will, upon such events and subject to such terms and conditions and upon receipt of such price, sell, assign, transfer and convey to such purchaser or its nominee (without recourse or warranty of any kind except against Liens on such Equipment Notes arising by, through or under such holder), all of the right, title and interest of such Note Holder in and to the Equipment Notes held by it, and such purchaser or its nominee shall assume all of such holder’s obligations under the Participation Agreement and hereunder.

Such option to purchase the Equipment Notes may be exercised by the Owner Trustee or the Owner Participant at any time following the occurrence of any of the following events, and in any such event the purchase price thereof shall equal for each Equipment Note, the aggregate unpaid Original Amount thereof, plus accrued and unpaid interest thereon to, but not including, the date of purchase and all other Secured Obligations owed, or then due and payable hereunder, to the holder thereof (including under the third paragraph of Section 2.02 hereof). Such option to purchase the Equipment Notes may be exercised (x) upon a Mortgagee Event or (y) in the event there shall have occurred and be continuing a Lease Event of Default or (z) upon either the Equipment Notes becoming due and payable pursuant to Section 4.04(b) hereof or the Mortgagee taking action or notifying the Owner Trustee that it intends to take action to foreclose the Lien of this Trust Indenture or otherwise commence the exercise of any significant remedy under this Trust Indenture or the Lease, provided that if such option is exercised pursuant to clause (y) at a time when there shall have occurred and be continuing for less than 120 days a Lease Event of Default, the purchase price thereof shall equal the price provided in the preceding sentence plus the Make-Whole Amount, if any.

Such option to purchase the Equipment Notes may be exercised by the Owner Trustee or the Owner Participant giving irrevocable written notice of its election of such option to the Mortgagee, which notice shall specify a date for such purchase within 15 days of the date of such notice.

(g) at any time either (i) the commencement of an involuntary case or other proceeding in respect of the Owner Participant, the Owner Trustee, the Trust or the Trust Estate under the federal bankruptcy Laws, as now constituted or hereafter amended, or any other applicable federal or state bankruptcy, insolvency or other similar Law in the United States or seeking the appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of the Owner Participant, the Owner Trustee, the Trust or the Trust Estate or for all or substantially all of its property, or seeking the winding-up or liquidation of its affairs and the continuation of any such case or other proceeding undismissed and unstayed for a period of 60 consecutive days; or (ii) the commencement by the Owner Participant, the Owner Trustee, the Trust or the Trust Estate of a voluntary case or proceeding under the federal bankruptcy Laws, as now constituted or hereafter amended, or any other applicable federal or state bankruptcy, insolvency or other similar Law in the United States, or the consent by the Owner Participant, the Owner Trustee, the Trust or the Trust Estate to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of the Owner Participant, the Owner Trustee, the Trust or the Trust Estate or for all or substantially all of its property, or the making by the Owner Participant, the Owner Trustee, the Trust or the Trust Estate of any assignment for the benefit of creditors or the Owner Participant or the Owner Trustee shall take any action to authorize any of the foregoing; provided, however, that an event referred to in this Section 4.02(g) with respect to the Owner Participant shall not constitute an Event of Default if within 30 days of the commencement of the case or proceeding a final non-appealable order, judgment or decree shall be entered in such case or proceeding by a court or a trustee, custodian, receiver or liquidator, to the effect that, no part of the Trust Estate (except for the Owner Participant’s beneficial interest therein) and no right, title or interest under the Trust Indenture Estate shall be included in, or be subject to, any declaration or adjudication of, or proceedings with respect to, the bankruptcy, insolvency or liquidation of the Owner Participant referred to in this Section 4.02(g).

SECTION 4.03. Certain Rights

The Mortgagee shall give the Note Holders, the Owner Trustee and the Owner Participant prompt written notice of any Event of Default of which the Mortgagee has Actual Knowledge and shall give the Note Holders, the Owner Trustee and the Owner Participant not less than ten Business Days’ prior written notice of the date (the “Enforcement Date”) on or after which the Mortgagee may, subject to the limitation set forth in Section 4.04(a), commence and consummate the exercise of any remedy or remedies described in Section 4.04, 4.05 or 4.06 hereof; provided, however, that in the event the Mortgagee shall have validly terminated the Lease, the Mortgagee shall not sell or lease, or otherwise afford the use of, the Aircraft or any portion thereof to the Lessee or any Affiliate thereof. Without limiting the generality of the foregoing, the Mortgagee shall give the Owner Trustee, the Owner Participant and the Lessee at least ten Business Days’ prior written notice (which may be given concurrently with notice of the Enforcement Date) of any declaration of the Lease to be in default pursuant to Sections 14 and 15 of the Lease or any termination of the Lease or of the exercise of any remedy or remedies pursuant to Section 15 of the Lease. If an Event of Default shall have occurred and be continuing, the Owner Trustee shall have the rights set forth below, any of which may be exercised directly by the Owner Participant.

If as a result of the occurrence of an Event of Default in respect of the nonpayment by Lessee of Basic Rent due under the Lease, the Mortgagee shall have insufficient funds to make any payment of Original Amount and interest on any Equipment Note on the day it becomes due and payable, the Owner Trustee may, but shall not be obligated to pay the Mortgagee prior to the Enforcement Date, in the manner provided in Section 2.04 hereof, for application in accordance with Section 3.01 hereof, an amount equal to the portion of the Original Amount and interest (including interest, if any, on any overdue payments of such portion of Original Amount and interest) then due and payable on the Equipment Notes, and, unless the Owner Trustee has cured Events of Default in respect of payments of Basic Rent on each of the three immediately preceding Basic Rent payment dates, or the Owner Trustee has cured six previous Events of Default in respect of payments of Basic Rent, such payment by the Owner Trustee shall, solely for purposes of this Trust Indenture be deemed to cure any Event of Default which would otherwise have arisen on account of the nonpayment by Lessee of such installment of Basic Rent (but not any other Default or Event of Default which shall have occurred and be continuing).

If any Event of Default (other than in respect of the nonpayment of Basic Rent by the Lessee) which can be cured by the payment of money has occurred, the Owner Trustee may, but shall not be obligated to, cure such Event of Default by making such payment prior to the Enforcement Date as is necessary to accomplish the observance or performance of the defaulted covenant, condition or agreement to the party entitled to the same.

Except as hereinafter in this Section 4.03 provided, the Owner Trustee shall not, as a result of exercising the right to cure any such Event of Default, obtain any Lien on any of the Mortgaged Property or any Rent payable under the Lease for or on account of costs or expenses incurred in connection with the exercise of such right, nor shall any claim of the Owner Trustee against Lessee or any other party for the repayment of such costs or expenses impair the prior right and security interest of the Mortgagee in and to the Mortgaged Property. Upon any payment by the Owner Trustee pursuant to the first or second preceding paragraphs of this Section 4.03, the Owner Trustee shall be subrogated to the rights of the Mortgagee and the Note Holders in respect of the Basic Rent which was overdue at the time of such payment and interest payable by the Lessee on account of its being overdue and any Supplemental Rent in respect of the reimbursement of amounts paid by Owner Trustee pursuant to the immediately preceding paragraph (but in either case shall have no rights as a secured party hereunder), and thereafter, the Owner Trustee shall be entitled (so long as the application thereof shall not give rise to an Event of Default hereunder) to receive such overdue Basic Rent or Supplemental Rent, as the case may be, and interest thereon upon receipt thereof by the Mortgagee; provided, however, that (i) if the Original Amount and interest on the Equipment Notes shall have become due and payable pursuant to Section 4.04(b) hereof, such subrogation shall, until the Secured Obligations shall have been paid in full, be subordinate to the rights of the Mortgagee, the Note Holders and the Indenture Indemnitees in respect of such payment of overdue Basic Rent, Supplemental Rent and such interest and (ii) the Owner Trustee shall not otherwise attempt to recover any such amount paid by it on behalf of the Lessee pursuant to this Section 4.03 except by demanding of the Lessee payment of such amount, or by commencing an action at law against the Lessee and obtaining and enforcing a judgment against the Lessee for the payment of such amount or taking appropriate action in a pending action at law against the Lessee (provided, that at no time while an Event of Default shall have occurred and be continuing shall any such demand be made or shall any such action be commenced (or continued) and any amounts nevertheless received by the Owner Trustee in respect thereof shall be held in trust for the benefit of, and promptly paid to, the Mortgagee for distribution as provided in Section 3.03 hereof).

Neither the Owner Trustee nor the Owner Participant shall have the right to cure any Lease Event of Default or Lease Default except as specified in this Section 4.03.

SECTION 4.04. Remedies

(a) If an Event of Default shall have occurred and be continuing and so long as the same shall continue unremedied, then and in every such case the Mortgagee may, subject to the second and third paragraphs of this Section 4.04(a), exercise any or all of the rights and powers and pursue any and all of the remedies pursuant to this Article IV and shall have and may exercise all of the rights and remedies of a secured party under the Uniform Commercial Code and, in the event such Event of Default is also a Lease Event of Default, any and all of the remedies pursuant to Section 15 of the Lease and pursuant to any Permitted Sublease assignment and may take possession of all or any part of the properties covered or intended to be covered by the Lien created hereby or pursuant hereto and may exclude the Owner Participant, the Owner Trustee and Lessee and all persons claiming under any of them wholly or partly therefrom; provided, that the Mortgagee shall give the Owner Trustee and the Owner Participant twenty days’ prior written notice of its intention to sell the Aircraft, and provided, further, that in the event the Mortgagee shall have validly terminated the Lease, the Mortgagee shall not sell or lease, or otherwise afford the use of, the Aircraft or any portion thereof to the Lessee or any Affiliate thereof. Unless an Event of Default not resulting from or relating to a Lease Event of Default has occurred and is continuing, the Owner Participant may bid at the sale and become the purchaser. Without limiting any of the foregoing, it is understood and agreed that the Mortgagee may exercise any right of sale of the Aircraft available to it, even though it shall not have taken possession of the Aircraft and shall not have possession thereof at the time of such sale.

Anything in this Trust Indenture to the contrary notwithstanding, the Mortgagee shall not be entitled to exercise any remedy hereunder as a result of an Event of Default which arises solely by reason of one or more events or circumstances which constitute a Lease Event of Default unless the Mortgagee as security assignee of the Owner Trustee shall have exercised or concurrently be exercising one or more of the dispossessory remedies provided for in Section 15 of the Lease with respect to the Aircraft; provided, however, that such requirement to exercise one or more of such remedies under the Lease shall not apply in circumstances where the Mortgagee is, and has been, for a continuous period in excess of 60 days or such other period as may be specified in Section 1110(a)(1)(A) of the Bankruptcy Code (such 60-day or other period being the “New Section 1110 Period”), involuntarily stayed or prohibited by applicable law or court order from exercising such remedies under the Lease (a “Continuous Stay Period”); provided further, however, that the requirement to exercise one or more of such remedies under the Lease shall nonetheless be applicable during a Continuous Stay Period subsequent to the expiration of the New Section 1110 Period to the extent that the continuation of such Continuous Stay Period subsequent to the expiration of the New Section 1110 Period (A) results from an agreement by the trustee or the debtor-in-possession in such proceeding during the New Section 1110 Period with the approval of the relevant court to perform the Lease in accordance with Section 1110(a)(1)(A) of the Bankruptcy Code and continues to perform as required by Section 1110(a)(1)(A-B) of the Bankruptcy Code or (B) is an extension of the New Section 1110 Period with the consent of the Mortgagee pursuant to Section 1110(b) of the Bankruptcy Code or (C) results from the Lessee’s assumption during the New Section 1110 Period with the approval of the relevant court of the Lease pursuant to Section 365 of the Bankruptcy Code and Lessee’s continuous performance of the Lease as so assumed or (D) is the consequence of the Mortgagee’s own failure to give any requisite notice to any person. In the event that the applicability of Section 1110 of the Bankruptcy Code to the Aircraft is being contested by Lessee in judicial proceedings, both of the Mortgagee and the Owner Trustee shall have the right to participate in such proceedings; provided that any such participation by the Owner Trustee shall not affect in any way any rights or remedy of the Mortgagee hereunder.

It is expressly understood and agreed that, subject only to the two preceding paragraphs, the inability, described in such paragraphs, of the Mortgagee to exercise any right or remedy under the Lease shall in no event and under no circumstances prevent the Mortgagee from exercising any or all of its rights, powers and remedies under this Trust Indenture, including, without limitation, this Article IV.

(b) If an Event of Default shall have occurred and be continuing, then and in every such case the Mortgagee may (and shall, upon receipt of a written demand therefor from a Majority in Interest of Note Holders), subject to Section 4.03 hereof, at any time, by delivery of written notice or notices to the Owner Trustee and the Owner Participant, declare all the Equipment Notes to be due and payable, whereupon the unpaid Original Amount of all Equipment Notes then outstanding, together with accrued but unpaid interest thereon (without Make-Whole Amount) and other amounts due thereunder, shall immediately become due and payable without presentment, demand, protest or notice, all of which are hereby waived; provided that if an Event of Default referred to in clause (g) of Section 4.02 hereof shall have occurred or a Lease Event of Default under Section 14.5 of the Lease shall have occurred, then and in every such case the unpaid Original Amount then outstanding, together with accrued but unpaid interest and all other amounts due thereunder and hereunder shall immediately and without further act become due and payable without presentment, demand, protest or notice, all of which are hereby waived; provided further that in the event of a reorganization proceeding involving the Lessee instituted under Chapter 11 of the Bankruptcy Code, if no Lease Event of Default (including any Lease Event of Default set forth in Section 14.3 of the Lease) and no other Event of Default (other than the failure to pay the Original Amount of the Equipment Notes which by such declaration shall have become payable) exists at any time after the consummation of such proceeding, such declaration shall be automatically rescinded without any further action on the part of any Note Holder.

This Section 4.04(b), however, is subject to the condition that, if at any time after the Original Amount of the Equipment Notes shall have become so due and payable, and before any judgment or decree for the payment of the money so due, or any thereof, shall be entered, all overdue payments of interest upon the Equipment Notes and all other amounts payable under the Equipment Notes (except the Original Amount of the Equipment Notes which by such declaration shall have become payable) shall have been duly paid, and every other Default and Event of Default with respect to any covenant or provision of this Trust Indenture shall have been cured, then and in every such case a Majority in Interest of Note Holders may (but shall not be obligated to), by written instrument filed with the Mortgagee, rescind and annul the Mortgagee’s declaration (or such automatic acceleration) and its consequences; but no such rescission or annulment shall extend to or affect any subsequent Default or Event of Default or impair any right consequent thereon.

Any acceleration pursuant to this Section 4.04(b) shall be automatically rescinded and any related declaration of an Event of Default annulled in the event that the Owner Trustee shall have cured, in accordance with Section 4.03 hereof, the Event of Default that resulted in such acceleration or declaration.

(c) The Note Holders shall be entitled, at any sale pursuant to Section 15 of the Lease or this Section 4.04, to credit against any purchase price bid at such sale by such holder all or any part of the unpaid obligations owing to such Note Holder and secured by the Lien of this Trust Indenture (only to the extent that such purchase price would have been paid to such Note Holder pursuant to Article III hereof if such purchase price were paid in cash and the foregoing provisions of this subsection (c) were not given effect).

(d) In the event of any sale of the Trust Indenture Estate, or any part thereof, pursuant to any judgment or decree of any court or otherwise in connection with the enforcement of any of the terms of this Trust Indenture, the unpaid Original Amount of all Equipment Notes then outstanding, together with accrued interest thereon (without Make-Whole Amount), and other amounts due thereunder, shall immediately become due and payable without presentment, demand, protest or notice, all of which are hereby waived.

(e) Notwithstanding anything contained herein, so long as the Pass Through Trustee under any Pass Through Trust Agreement (or its designee) is a Note Holder, the Mortgagee will not be authorized or empowered to acquire title to any Mortgaged Property or take any action with respect to any Mortgaged Property so acquired by it if such acquisition or action would cause any Trust to fail to qualify as a “grantor trust” for federal income tax purposes.

SECTION 4.05. Return of Aircraft, Etc.

(a) If an Event of Default shall have occurred and be continuing and the Equipment Notes have been accelerated, subject to Section 4.03 hereof and unless the Owner Trustee or the Owner Participant shall have elected to purchase the Equipment Notes, at the request of the Mortgagee, the Owner Trustee shall promptly execute and deliver to the Mortgagee such instruments of title and other documents as the Mortgagee may deem necessary or advisable to enable the Mortgagee or an agent or representative designated by the Mortgagee, at such time or times and place or places as the Mortgagee may specify, to obtain possession of all or any part of the Mortgaged Property included in the Trust Indenture Estate to which the Mortgagee shall at the time be entitled hereunder. If the Owner Trustee shall for any reason fail to execute and deliver such instruments and documents after such request by the Mortgagee, the Mortgagee may (i) obtain a judgment conferring on the Mortgagee the right to immediate possession and requiring the Owner Trustee to execute and deliver such instruments and documents to the Mortgagee, to the entry of which judgment the Owner Trustee hereby specifically consents to the fullest extent permitted by Law, and (ii) pursue all or part of such Mortgaged Property wherever it may be found and, in the event that a Lease Event of Default has occurred and is continuing, may enter any of the premises of Lessee wherever such Mortgaged Property may be or be supposed to be and search for such Mortgaged Property and take possession of and remove such Mortgaged Property. All expenses of obtaining such judgment or of pursuing, searching for and taking such property shall, until paid, be secured by the Lien of this Trust Indenture.

(b) Upon every such taking of possession, the Mortgagee may, from time to time, at the expense of the Mortgaged Property, make all such expenditures for maintenance, use, operation, storage, insurance, leasing, control, management, disposition, modifications or alterations to and of the Mortgaged Property, as it may deem proper. In each such case, the Mortgagee shall have the right to maintain, use, operate, store, insure, lease, control, manage, dispose of, modify or alter the Mortgaged Property and to carry on the business and to exercise all rights and powers of the Owner Participant and the Owner Trustee relating to the Mortgaged Property, as the Mortgagee shall deem best, including the right to enter into any and all such agreements with respect to the maintenance, use, operation, storage, insurance, leasing, control, management, disposition, modification or alteration of the Mortgaged Property or any part thereof as the Mortgagee may determine, and the Mortgagee shall be entitled to collect and receive directly all tolls, rents (including Rent), revenues, issues, income, products and profits of the Mortgaged Property and every part thereof, except Excluded Payments, without prejudice, however, to the right of the Mortgagee under any provision of this Trust Indenture to collect and receive all cash held by, or required to be deposited with, the Mortgagee hereunder other than Excluded Payments. Such tolls, rents (including Rent), revenues, issues, income, products and profits shall be applied to pay the expenses of the maintenance, use, operation, storage, insurance, leasing, control, management, disposition, improvement, modification or alteration of the Mortgaged Property and of conducting the business thereof, and to make all payments which the Mortgagee may be required or may elect to make, if any, for taxes, assessments, insurance or other proper charges upon the Mortgaged Property or any part thereof (including the employment of engineers and accountants to examine, inspect and make reports upon the properties and books and records of the Owner Trustee), and all other payments which the Mortgagee may be required or authorized to make under any provision of this Trust Indenture, as well as just and reasonable compensation for the services of the Mortgagee, and of all persons properly engaged and employed by the Mortgagee with respect hereto.

SECTION 4.06. Remedies Cumulative

Each and every right, power and remedy given to the Mortgagee specifically or otherwise in this Trust Indenture shall be cumulative and shall be in addition to every other right, power and remedy herein specifically given or now or hereafter existing at Law, in equity or by statute, and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time and as often and in such order as may be deemed expedient by the Mortgagee, and the exercise or the beginning of the exercise of any power or remedy shall not be construed to be a waiver of the right to exercise at the same time or thereafter any other right, power or remedy. No delay or omission by the Mortgagee in the exercise of any right, remedy or power or in the pursuance of any remedy shall impair any such right, power or remedy or be construed to be a waiver of any default on the part of the Owner Trustee or Lessee or to be an acquiescence therein.

SECTION 4.07. Discontinuance of Proceedings

In case the Mortgagee shall have instituted any proceeding to enforce any right, power or remedy under this Trust Indenture by foreclosure, entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Mortgagee, then and in every such case the Owner Trustee, the Mortgagee and Lessee shall, subject to any determination in such proceedings, be restored to their former positions and rights hereunder with respect to the Mortgaged Property, and all rights, remedies and powers of the Owner Trustee, the Mortgagee or Lessee shall continue as if no such proceedings had been instituted.

SECTION 4.08. Waiver of Past Defaults

Upon written instruction from a Majority in Interest of Note Holders, the Mortgagee shall waive any past Default hereunder and its consequences and upon any such waiver such Default shall cease to exist and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Trust Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon; provided, that in the absence of written instructions from all the Note Holders, the Mortgagee shall not waive any Default (i) in the payment of the Original Amount, Make-Whole Amount, if any, and interest and other amounts due under any Equipment Note then outstanding, or (ii) in respect of a covenant or provision hereof which, under Article IX hereof, cannot be modified or amended without the consent of each Note Holder.

SECTION 4.09. Appointment of Receiver

The Mortgagee shall, as a matter of right, be entitled to the appointment of a receiver (who may be the Mortgagee or any successor or nominee thereof) for all or any part of the Mortgaged Property, whether such receivership be incidental to a proposed sale of the Mortgaged Property or the taking of possession thereof or otherwise, and the Owner Trustee hereby consents to the appointment of such a receiver and will not oppose any such appointment. Any receiver appointed for all or any part of the Mortgaged Property shall be entitled to exercise all the rights and powers of the Mortgagee with respect to the Mortgaged Property.

SECTION 4.10. Mortgagee Authorized to Execute Bills of Sale, Etc.

Subject to the provisions of this Trust Indenture, the Owner Trustee irrevocably appoints the Mortgagee the true and lawful attorney-in-fact of the Owner Trustee (which appointment is coupled with an interest) in its name and stead and on its behalf, for the purpose of effectuating any sale, assignment, transfer or delivery for the enforcement of the Lien of this Trust Indenture, whether pursuant to foreclosure or power of sale, assignments and other instruments as may be necessary or appropriate, with full power of substitution, the Owner Trustee hereby ratifying and confirming all that such attorney or any substitute shall do by virtue hereof in accordance with applicable law. Nevertheless, if so requested by the Mortgagee or any purchaser, the Owner Trustee shall ratify and confirm any such sale, assignment, transfer or delivery, by executing and delivering to the Mortgagee or such purchaser all bills of sale, assignments, releases and other proper instruments to effect such ratification and confirmation as may be designated in any such request.

SECTION 4.11. Rights of Note Holders to Receive Payment

Notwithstanding any other provision of this Trust Indenture, the right of any Note Holder to receive payment of principal of, and premium, if any, and interest on an Equipment Note on or after the respective due dates expressed in such Equipment Note, or to bring suit for the enforcement of any such payment on or after such respective dates in accordance with the terms hereof, shall not be impaired or affected without the consent of such Note Holder.

ARTICLE V

DUTIES OF THE MORTGAGEE

SECTION 5.01. Notice of Event of Default

If the Mortgagee shall have Actual Knowledge of an Event of Default or of a Default arising from a failure to pay Rent, the Mortgagee shall give prompt written notice thereof to the Owner Trustee, the Owner Participant, Lessee, and each Note Holder. Subject to the terms of Sections 2.13, 4.03, 4.04, 4.08, 5.02 and 5.03 hereof, the Mortgagee shall take such action, or refrain from taking such action, with respect to such Event of Default or Default (including with respect to the exercise of any rights or remedies hereunder) as the Mortgagee shall be instructed in writing by a Majority in Interest of Note Holders. Subject to the provisions of Section 5.03, if the Mortgagee shall not have received instructions as above provided within 20 days after mailing notice of such Event of Default to the Note Holders, the Mortgagee may, subject to instructions thereafter received pursuant to the preceding provisions of this Section 5.01, take such action, or refrain from taking such action, but shall be under no duty to take or refrain from taking any action, with respect to such Event of Default or Default as it shall determine advisable in the best interests of the Note Holders; provided, however, that the Mortgagee may not sell the Aircraft or any Engine without the consent of a Majority in Interest of Note Holders. For all purposes of this Trust Indenture, in the absence of Actual Knowledge on the part of the Mortgagee, the Owner Trustee or the Owner Participant, the Mortgagee, the Owner Trustee or the Owner Participant, as the case may be, shall not be deemed to have knowledge of a Default or an Event of Default (except, in the case of the Mortgagee, the failure of Lessee to pay any installment of Basic Rent within one Business Day after the same shall become due, if any portion of such installment was then required to be paid to the Mortgagee, which failure shall constitute knowledge of a Default) unless notified in writing by Lessee, the Owner Trustee, the Owner Participant or one or more Note Holders.

SECTION 5.02. Action Upon Instructions; Certain Rights and Limitations

(a) Subject to the terms of Sections 2.13, 4.03, 4.04(a) and (b), 4.08, 5.01 and 5.03 hereof, upon the written instructions at any time and from time to time of a Majority in Interest of Note Holders, the Mortgagee shall, subject to the terms of this Section 5.02, take such of the following actions as may be specified in such instructions: (i) give such notice or direction or exercise such right, remedy or power hereunder as shall be specified in such instructions; (ii) give such notice or direction or exercise such right, remedy or power under the Lease, the Participation Agreement, the Purchase Agreement, the Purchase Agreement Assignment, or any other part of the Trust Indenture Estate as shall be specified in such instructions; and (iii) approve as satisfactory to the Mortgagee all matters required by the terms of the Lease to be satisfactory to the Owner Trustee, it being understood that without the written instructions of a Majority in Interest of Note Holders, the Mortgagee shall not approve any such matter as satisfactory to the Mortgagee; provided, that anything contained in this Trust Indenture, the Lease or the other Operative Agreements to the contrary notwithstanding, but subject to the next paragraph hereof:

(1) the Owner Trustee or the Owner Participant, may, without the consent of the Mortgagee, demand, collect, ▇▇▇ for or otherwise obtain all amounts included in Excluded Payments from Lessee and seek legal or equitable remedies to require Lessee to maintain the insurance coverage referred to in Section 11 of the Lease (or the comparable provisions of any assigned Permitted Sublease) provided, that the rights referred to in this clause (1) shall not be deemed to include the exercise of any remedies provided for in Section 15 of the Lease other than the right to proceed by appropriate court action, either at Law or in equity, to enforce payment by Lessee of such amounts included in Excluded Payments or performance by Lessee of such insurance covenant or to recover damages for the breach thereof or for specific performance of any other term of the Lease (or the comparable provisions of any assigned Permitted Sublease);

(2) (A) the Mortgagee shall not, without the consent of the Owner Trustee, enter into, execute or deliver amendments or modifications in respect of any of the provisions of the Lease[, any assigned Permitted Sublease or any Permitted Sublease assignment]*, and (B) unless a Mortgagee Event shall have occurred and be continuing, the Mortgagee shall not, without the consent of the Owner Trustee, which consent shall not be withheld if no right or interest of the Owner Trustee or the Owner Participant shall be diminished or impaired thereby, (i) enter into, execute or deliver waivers or consents in respect of any of the provisions of the Lease, or (ii) approve any accountants, engineers, appraisers or counsel as satisfactory to render services for or issue opinions to the Owner Trustee pursuant to the Operative Agreements, provided that whether or not any Mortgagee Event has occurred and is continuing, the Owner Trustee’s consent shall be required with respect to any waivers or consents in respect of any of the provisions of Section 5, 7 or 11 of the Lease, or of any other Section of the Lease to the extent such action shall affect (y) the amount or timing of, or the right to enforce payment of any Excluded Payment or (z) the amount or timing of any amounts payable by the Lessee under the Lease as originally executed (or as subsequently modified with the consent of the Owner Trustee) which, absent the occurrence and continuance of an Event of Default hereunder, would be distributable to the Owner Trustee under Article III hereof;

(3) whether or not a Default or Event of Default under the Trust Indenture has occurred and is continuing, the Owner Trustee and the Owner Participant shall have the right, together with the Mortgagee, (i) to receive from Lessee or any Permitted Sublessee certificates and other documents and information which Lessee is required to give or furnish to the Owner Trustee or the Lessor pursuant to any Operative Agreement and (ii) to inspect in accordance with the Lease the Airframe and Engines and all Aircraft Documents;

(6) whether or not a Default or Event of Default under the Trust Indenture has occurred and is continuing, the Owner Trustee may, without the consent of the Mortgagee, (i) solicit and make bids with respect to the Aircraft under Section 9 of the Lease in respect of a termination of the Lease by Lessee pursuant to Section 9 thereof, (ii) determine Fair Market Sales Value and Fair Market Rental Value under Section 17 of the Lease for all purposes except following a Mortgagee Event pursuant to Section 15 of the Lease, and (iii) make an election pursuant to and in accordance with the provisions of Sections 9.1(b), 9.2 and 9.3 of the Lease; and

(7) so long as no Mortgagee Event shall have occurred and be continuing, all other rights of the “Lessor” under the Lease or any assigned Permitted Sublease shall be exercised by the Owner Trustee to the exclusion of the Mortgagee including, without limitation, the right to (i) exercise all rights with respect to Lessee’s use and operation, modification or maintenance of the Aircraft and any Engine which the Lease specifically confers on the Lessor, and (ii) consent to and approve any assignment pursuant to Section 13 of the Lease; provided that the foregoing shall not (x) limit (A) any rights separately granted to the Mortgagee under the Operative Agreements or (B) the right of the Mortgagee to receive any funds to be delivered to the “Lessor” under the Lease (except with respect to Excluded Payments) and under the Purchase Agreement or (y) confer upon the Owner Trustee the right to adversely affect the validity or enforceability of the Lien of this Indenture.

Notwithstanding anything to the contrary contained herein (including this Section 5.02), the Mortgagee shall have the right, to the exclusion of the Owner Trustee and the Owner Participant, to (A) declare the Lease to be in default under Section 15 thereof and (B) subject only to the provisions of Sections 4.03, 4.04(a) and (b) and 2.13 hereof, exercise the remedies set forth in such Section 15 (other than in connection with Excluded Payments and provided that each of the Owner Trustee, Owner Participant and Mortgagee shall independently retain the rights set forth in clause (ii) of Section 15.1.5 of the Lease) at any time that a Lease Event of Default shall have occurred and be continuing. Further and for the avoidance of doubt, and anything to the contrary contained herein (including this Section 5.02), in no event may the Owner Trustee amend or otherwise modify the provisions of Section 3.2.1(e) of the Lease or of the final sentence of the definition of Stipulated Loss Value or Termination Value, in any such case, without the prior written consent of the Mortgagee.

The Mortgagee will execute and the Owner Trustee will file or cause to be filed such continuation statements with respect to financing statements relating to the security interest created hereunder in the Trust Indenture Estate as may be specified from time to time in written instructions of a Majority in Interest of Note Holders (which instructions shall be accompanied by the form of such continuation statement so to be filed). The Mortgagee will furnish to each Note Holder (and, during the continuation of a Mortgagee Event, to the Owner Trustee and Owner Participant), promptly upon receipt thereof, duplicates or copies of all reports, notices, requests, demands, certificates and other instruments furnished to the Mortgagee under the Lease or hereunder, including, without limitation, a copy of any notice given pursuant to Section 9.1 of the Lease and a copy of each report or notice received pursuant to Section 9 and Paragraph E of Annex D of the Lease, respectively to the extent that the same shall not have been furnished to such holder pursuant hereto or the Lease.

(b) If any Lease Event of Default shall have occurred and be continuing and the Owner Trustee shall not have cured fully such Lease Event of Default under and in accordance with Section 4.03 hereof, on request of a Majority in Interest of Note Holders, the Mortgagee shall declare the Lease to be in default pursuant to Section 15 thereof and exercise those remedies specified by such Note Holders. The Mortgagee agrees to provide to the Note Holders, the Owner Trustee and the Owner Participant concurrently with such declaration by the Mortgagee, notice of such declaration by the Mortgagee.

SECTION 5.03. Indemnification

The Mortgagee agrees that it shall look solely to the Note Holders for the satisfaction of any indemnity (except expenses for foreclosure of the type referred to in clause “First” of Section 3.03 hereof) owed to it pursuant to this Section 5.03. The Mortgagee shall not be under any obligation to take any action under this Trust Indenture or any other Operative Agreement and nothing herein or therein shall require the Mortgagee to expend or risk its own funds or otherwise incur the risk of any financial liability in the performance of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it (the written indemnity of any Note Holder who is a QIB, signed by an authorized officer thereof, in favor of, delivered to and in form reasonably satisfactory to the Mortgagee shall be accepted as reasonable assurance of adequate indemnity). The Mortgagee shall not be required to take any action under Section 5.01 (other than the first sentence thereof) or 5.02 or Article IV hereof, nor shall any other provision of this Trust Indenture or any other Operative Agreement be deemed to impose a duty on the Mortgagee to take any action, if the Mortgagee shall have been advised by counsel that such action is contrary to the terms hereof or of the Lease or is otherwise contrary to Law.

SECTION 5.04. No Duties Except as Specified in Trust Indenture or Instructions

The Mortgagee shall not have any duty or obligation to use, operate, store, lease, control, manage, sell, dispose of or otherwise deal with the Aircraft or any other part of the Trust Indenture Estate, or to otherwise take or refrain from taking any action under, or in connection with, this Trust Indenture or any part of the Trust Indenture Estate, except as expressly provided by the terms of this Trust Indenture or as expressly provided in written instructions from Note Holders as provided in this Trust Indenture; and no implied duties or obligations shall be read into this Trust Indenture against the Mortgagee. The Mortgagee agrees that it will in its individual capacity and at its own cost and expense (but without any right of indemnity in respect of any such cost or expense under Section 7.01 hereof), promptly take such action as may be necessary duly to discharge all liens and encumbrances on any part of the Trust Indenture Estate which result from claims against it in its individual capacity not related to the ownership of the Aircraft or the administration of the Trust Indenture Estate or any other transaction pursuant to this Trust Indenture or any document included in the Trust Indenture Estate.

SECTION 5.05. No Action Except Under Lease, Trust Indenture or Instructions

The Owner Trustee and the Mortgagee agree that they will not use, operate, store, lease, control, manage, sell, dispose of or otherwise deal with the Aircraft or any other part of the Trust Indenture Estate except (i) as required by the terms of the Lease or (ii) in accordance with the powers granted to, or the authority conferred upon, the Owner Trustee and the Mortgagee pursuant to this Trust Indenture and in accordance with the express terms hereof.

SECTION 5.06. Replacement Airframes and Replacement Engines

At any time an Airframe or Engine is to be replaced under or pursuant to Section 10 of the Lease by a Replacement Airframe or Replacement Engine, if no Lease Event of Default is continuing, the Owner Trustee shall direct the Mortgagee to execute and deliver to the Owner Trustee an appropriate instrument releasing such Airframe and/or Engine as appropriate from the Lien of this Trust Indenture and the Mortgagee shall execute and deliver such instrument as aforesaid, but only upon compliance by Lessee with the applicable provisions of Section 10 of the Lease.

SECTION 5.07. Indenture Supplements for Replacements

If a Replacement Airframe or Replacement Engine is being substituted as contemplated by Section 10 of the Lease, the Owner Trustee and the Mortgagee agree for the benefit of the Note Holders and Lessee, subject to fulfillment of the conditions precedent and compliance by Lessee with its obligations set forth in Section 10 of the Lease and the requirements of Section 5.06 hereof with respect to such Replacement Airframe or Replacement Engine, to execute and deliver a Lease Supplement and a Trust Indenture Supplement, as applicable, as contemplated by Section 10 of the Lease.

SECTION 5.08. Effect of Replacement

In the event of the substitution of an Airframe or of a Replacement Engine pursuant to Section 10 of the Lease, all provisions of this Trust Indenture relating to the Airframe or Engine or Engines being replaced shall be applicable to such Replacement Airframe or Replacement Engine or Engines with the same force and effect as if such Replacement Airframe or Replacement Engine or Engines were the same airframe or engine or engines, as the case may be, as the Airframe or Engine or Engines being replaced but for the Event of Loss with respect to the Airframe or Engine or Engines being replaced.

SECTION 5.09. Investment of Amounts Held by Mortgagee

Any amounts held by the Mortgagee as assignee of the Owner Trustee’s rights to hold monies for security pursuant to Section 4.4 of the Lease shall be held in accordance with the terms of such Section and the Mortgagee agrees, for the benefit of Lessee, to perform the duties of the Owner Trustee under such Section. Any amounts held by the Mortgagee pursuant to the proviso to Clause “Second” of the first sentence of Section 3.01, pursuant to Section 3.02, or pursuant to any provision of any other Operative Agreement providing for amounts to be held by the Mortgagee which are not distributed pursuant to the other provisions of Article III hereof shall be invested by the Mortgagee from time to time in Cash Equivalents as directed by the Owner Trustee so long as the Mortgagee may acquire the same using its best efforts. Unless otherwise expressly provided in this Trust Indenture, any income realized as a result of any such investment, net of the Mortgagee’s reasonable fees and expenses in making such investment, shall be held and applied by the Mortgagee in the same manner as the principal amount of such investment is to be applied and any losses, net of earnings and such reasonable fees and expenses, shall be charged against the principal amount invested. The Mortgagee shall not be liable for any loss resulting from any investment required to be made by it under this Trust Indenture other than by reason of its willful misconduct or gross negligence, and any such investment may be sold (without regard to its maturity) by the Mortgagee without instructions whenever such sale is necessary to make a distribution required by this Trust Indenture.

SUCCESSOR AND SEPARATE TRUSTEES

SECTION 8.01. Notice of Successor Owner Trustee

In the case of any appointment of a successor to the Owner Trustee pursuant to the Trust Agreement including upon any merger, conversion, consolidation or sale of substantially all of the corporate trust business of the Owner Trustee pursuant to the Trust Agreement, the successor Owner Trustee shall give prompt written notice thereof to the Mortgagee, Lessee and the Note Holders.

SECTION 8.02. Resignation of Mortgagee; Appointment of Successor

(a) The Mortgagee or any successor thereto may resign at any time without cause by giving at least 30 days’ prior written notice to Lessee, the Owner Trustee, the Owner Participant and each Note Holder, such resignation to be effective upon the acceptance of the trusteeship by a successor Mortgagee. In addition, a Majority in Interest of Note Holders may at any time (but only with the consent of the Lessee, which consent shall not be unreasonably withheld, except that such consent shall not be necessary if a Lease Event of Default is continuing) remove the Mortgagee without cause by an instrument in writing delivered to the Owner Trustee, Lessee, the Owner Participant and the Mortgagee, and the Mortgagee shall promptly notify each Note Holder thereof in writing, such removal to be effective upon the acceptance of the trusteeship by a successor Mortgagee. In the case of the resignation or removal of the Mortgagee, a Majority in Interest of Note Holders may appoint a successor Mortgagee by an instrument signed by such holders, which successor, so long as no Lease Event of Default shall have occurred and be continuing, shall be subject to Lessee’s reasonable approval. If a successor Mortgagee shall not have been appointed within 30 days after such notice of resignation or removal, the Mortgagee, the Owner Trustee, the Owner Participant or any Note Holder may apply to any court of competent jurisdiction to appoint a successor Mortgagee to act until such time, if any, as a successor shall have been appointed as above provided. The successor Mortgagee so appointed by such court shall immediately and without further act be superseded by any successor Mortgagee appointed as above provided.

(b) Any successor Mortgagee, however appointed, shall execute and deliver to the Owner Trustee, the predecessor Mortgagee and the Lessee an instrument accepting such appointment and assuming the obligations of the Mortgagee under the Participation Agreement arising from and after the time of such appointment, and thereupon such successor Mortgagee, without further act, shall become vested with all the estates, properties, rights, powers and duties of the predecessor Mortgagee hereunder in the trust hereunder applicable to it with like effect as if originally named the Mortgagee herein; but nevertheless upon the written request of such successor Mortgagee, such predecessor Mortgagee shall execute and deliver an instrument transferring to such successor Mortgagee, upon the trusts herein expressed applicable to it, all the estates, properties, rights and powers of such predecessor Mortgagee, and such predecessor Mortgagee shall duly assign, transfer, deliver and pay over to such successor Mortgagee all monies or other property then held by such predecessor Mortgagee hereunder.

(c) Any successor Mortgagee, however appointed, shall be a bank or trust company having its principal place of business in the Borough of Manhattan, City and State of New York; Chicago, Illinois; Hartford, Connecticut; Wilmington, Delaware; or Boston, Massachusetts and having (or whose obligations under the Operative Agreements are guaranteed by an affiliated entity having) a combined capital and surplus of at least $100,000,000, if there be such an institution willing, able and legally qualified to perform the duties of the Mortgagee hereunder upon reasonable or customary terms.

(d) Any corporation into which the Mortgagee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Mortgagee shall be a party, or any corporation to which substantially all the corporate trust business of the Mortgagee may be transferred, shall, subject to the terms of paragraph (c) of this Section 8.02, be a successor Mortgagee and the Mortgagee under this Trust Indenture without further act.

SECTION 8.03. Appointment of Additional and Separate Trustees

(a) Whenever (i) the Mortgagee shall deem it necessary or desirable in order to conform to any Law of any jurisdiction in which all or any part of the Trust Indenture Estate shall be situated or to make any claim or bring any suit with respect to or in connection with the Trust Indenture Estate, this Trust Indenture, any other Indenture Agreement, the Equipment Notes or any of the transactions contemplated by the Participation Agreement, (ii) the Mortgagee shall be advised by counsel satisfactory to it that it is so necessary or prudent in the interests of the Note Holders (and the Mortgagee shall so advise the Owner Trustee and Lessee), or (iii) the Mortgagee shall have been requested to do so by a Majority in Interest of Note Holders, then in any such case, the Mortgagee and, upon the written request of the Mortgagee, the Owner Trustee, shall execute and deliver an indenture supplemental hereto and such other instruments as may from time to time be necessary or advisable either (1) to constitute one or more bank or trust companies or one or more persons approved by the Mortgagee, either to act jointly with the Mortgagee as additional trustee or trustees of all or any part of the Trust Indenture Estate, or to act as separate trustee or trustees of all or any part of the Trust Indenture Estate, in each case with such rights, powers, duties and obligations consistent with this Trust Indenture as may be provided in such supplemental indenture or other instruments as the Mortgagee or a Majority in Interest of Note Holders may deem necessary or advisable, or (2) to clarify, add to or subtract from the rights, powers, duties and obligations theretofore granted any such additional or separate trustee, subject in each case to the remaining provisions of this Section 8.03. If the Owner Trustee shall not have taken any action requested of it under this Section 8.03(a) that is permitted or required by its terms within 15 days after the receipt of a written request from the Mortgagee so to do, or if an Event of Default shall have occurred and be continuing, the Mortgagee may act under the foregoing provisions of this Section 8.03(a) without the concurrence of the Owner Trustee, and the Owner Trustee hereby irrevocably appoints (which appointment is coupled with an interest) the Mortgagee, its agent and attorney-in-fact to act for it under the foregoing provisions of this Section 8.03(a) in either of such contingencies. The Mortgagee may, in such capacity, execute, deliver and perform any such supplemental indenture, or any such instrument, as may be required for the appointment of any such additional or separate trustee or for the clarification of, addition to or subtraction from the rights, powers, duties or obligations theretofore granted to any such additional or separate trustee. In case any additional or separate trustee appointed under this Section 8.03(a) shall die, become incapable of acting, resign or be moved, all the assets, property, rights, powers, trusts, duties and obligations of such additional or separate trustee shall revert to the Mortgagee until a successor additional or separate trustee is appointed as provided in this Section 8.03(a).

(b) No additional or separate trustee shall be entitled to exercise any of the rights, powers, duties and obligations conferred upon the Mortgagee in respect of the custody, investment and payment of monies and all monies received by any such additional or separate trustee from or constituting part of the Trust Indenture Estate or otherwise payable under any Operative Agreement to the Mortgagee shall be promptly paid over by it to the Mortgagee. All other rights, powers, duties and obligations conferred or imposed upon any additional or separate trustee shall be exercised or performed by the Mortgagee and such additional or separate trustee jointly except to the extent that applicable Law of any jurisdiction in which any particular act is to be performed renders the Mortgagee incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations (including the holding of title to all or part of the Trust Indenture Estate in any such jurisdiction) shall be exercised and performed by such additional or separate trustee. No additional or separate trustee shall take any discretionary action except on the instructions of the Mortgagee or a Majority in Interest of Note Holders. No trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder, except that the Mortgagee shall be liable for the consequences of its lack of reasonable care in selecting, and the Mortgagee’s own actions in acting with, any additional or separate trustee. Each additional or separate trustee appointed pursuant to this Section 8.03 shall be subject to, and shall have the benefit of Articles IV through VIII and Article X hereof insofar as they apply to the Mortgagee. The powers of any additional or separate trustee appointed pursuant to this Section 8.03 shall not in any case exceed those of the Mortgagee hereunder.

(c) If at any time the Trustee shall deem it no longer necessary or in order to conform to any such Law or take any such action or shall be advised by such counsel that it is no longer so necessary or desirable in the interest of the Note Holders, or in the event that the Mortgagee shall have been requested to do so in writing by a Majority in Interest of Note Holders, the Mortgagee and, upon the written request of the Mortgagee, the Owner Trustee, shall execute and deliver an indenture supplemental hereto and all other instruments and agreements necessary or proper to remove any additional or separate trustee. The Mortgagee may act on behalf of the Owner Trustee under this Section 8.03(c) when and to the extent it could so act under Section 8.03(a) hereof.
