LOAN AGREEMENT

THIS LOAN AGREEMENT (this “Agreement”) is entered into as of February 12, 2007 among (a) AIRTRAN AIRWAYS, INC. (“Borrower”), a Delaware corporation, (b) THE PARTIES IDENTIFIED IN SCHEDULE 1 HERETO AS LENDERS (the “Lenders”) and (c) WELLS FARGO BANK NORTHWEST, NATIONAL ASSOCIATION, a national banking association, in its individual capacity (“WFB”).

RECITALS

A. Borrower and Airframe Manufacturer have entered into the Purchase Agreement, pursuant to which Airframe Manufacturer agreed to manufacture and sell to Borrower, and Borrower agreed to purchase and take delivery of, among other things, six (6) Boeing model 737-7BD aircraft, each equipped with two (2) CFM International model CFM56-7B20 engines, to be delivered in the Scheduled Delivery Months (the “Aircraft”).

B. To enable Borrower to purchase and take delivery of each of the Aircraft on the applicable Delivery Dates, Borrower desires to borrow from Lenders, and Lenders desire to lend to Borrower, a portion of the purchase price of each of the Aircraft.

C. The parties to this Agreement wish to set forth in this Agreement the terms and conditions upon and subject to which the foregoing transactions shall be effected.

The parties hereto agree as follows:

1. DEFINITIONS AND CONSTRUCTION

The terms defined in Annex A, when capitalized as in Annex A, have the same meanings when used in this Agreement. Annex A also contains rules of usage that control construction in this Agreement.

2. SECURED LOANS; CLOSING

2.1

Making of Loans; Creation of Mortgages; Issuance of Equipment Notes.

In respect of each Aircraft and subject to the terms and conditions of this Agreement, on the applicable Delivery Date of each Aircraft (each such date a “Closing Date”):

(a) each Lender severally agrees to make a secured loan to Borrower in the amount of such Lender’s Commitment for such Aircraft;

(b) WFB, in its individual capacity and as a mortgagee, and Borrower shall enter into the Mortgage in respect of such Aircraft; and

(c) pursuant to Section 2 of such Mortgage, Borrower shall issue an Equipment Note to each Lender having a Commitment for such Aircraft, dated the Applicable Closing Date, for an aggregate principal amount equal to the amount of the secured loan made by such Lender on such date.

No Closing Date for any Aircraft shall occur after the Commitment Termination Date.

If any Lender shall default in its obligation to make the amount of its Commitment available pursuant to this Article 2 in respect of any Aircraft, except as provided below in this Section 2.1 with respect to the relevant Initial Lenders, no other Lender shall have an obligation to increase the amount of its Commitment for such Aircraft and, notwithstanding the further provisions of this paragraph, the obligations of the non-defaulting Lenders shall remain subject to the terms and conditions set forth in this Agreement. If a Lender to whom an Initial Lender has transferred its Commitment in whole or in part pursuant to Section 7.1 with respect to an Aircraft fails to perform its obligation to make a secured loan on an Applicable Closing Date, such Initial Lender shall be obligated to make a secured loan or additional secured loan, as the case may be, on such Applicable Closing Date in an amount equal to the amount of the secured loan that such Lender was so obligated to, but did not, make; provided, this sentence shall not apply if Borrower has elected to approve (acting in its sole discretion and without any obligation to do so) in writing any such Lender to whom an Initial Lender has so transferred its Commitment. In the event that the preceding sentence is applicable and such Initial Lender is obligated to make a secured loan or additional secured loan (as the case may be), the Commitment of the Initial Lender shall be increased by the amount of such secured loan or additional secured loan (as the case may be), and the Commitment of the affected Lender shall be reduced by an equivalent amount, effective on the Applicable Closing Date. In the circumstances of the second preceding sentence, such Lender shall be liable to such Initial Lender (but not Borrower) for any damages attributable to its failure to make the secured loan in question which was made, instead, by such Initial Lender.

2.2

Procedure for Funding of Secured Loans.

(a) Notice of Scheduled Delivery Date. In the case of each Aircraft, Borrower agrees to give each Applicable Lender, the Applicable Mortgagee and SkyBlue Capital LLC written notice or telephonic notice (to be confirmed promptly in writing) of the date such Aircraft is scheduled to be delivered (the “Scheduled Delivery Date”) so that such notice is received by each such Lender not later than 4:30 p.m., New York City time, on the tenth (10^th) day prior to the Scheduled Delivery Date. Borrower undertakes to promptly notify each such Lender of any amendment or change in the Scheduled Delivery Date.

(b) Drawdown Notice. No later than 10:00 a.m., New York City time, on the third (3rd) Business Day prior to the Scheduled Delivery Date for any Aircraft, each Applicable Lender, the Applicable Mortgagee and SkyBlue Capital LLC shall receive the Drawdown Notice from Borrower in respect of such Aircraft, receipt of which shall, subject to the conditions contained in this Agreement, oblige Borrower to borrow an amount equal to the Commitment for such Aircraft (or such lesser amount specified in such Drawdown Notice) on the date stated and on the terms herein contained.

(c) Disbursement of Funds. In the case of each Aircraft, each Applicable Lender agrees, subject to the terms and conditions of this Agreement, to make its Commitment for such Aircraft available for disbursement to or on behalf of Borrower, in each case in immediately available funds by 11:00 a.m., New York City time, on the Scheduled Delivery Date for such Aircraft in the amount set out in the Drawdown Notice. In order to facilitate the timely closing of the transactions contemplated hereby, for any Aircraft, Borrower, by delivery of the Drawdown Notice to the Applicable Lenders, irrevocably instructs, subject to its rights to postpone under Section 2.2(d) below, such Lenders to wire transfer (for receipt by no later than 11:00 a.m. New York City time) on the Scheduled Delivery Date for such Aircraft its Commitment for such Aircraft by the wiring of immediately available funds (reference: AirTran N AT) to the account of WFB specified in Schedule 1 hereto (the “Account”). The funds so paid by each such Lender (the “Deposit”) into the Account for any Aircraft are to be held by WFB for account of such Lender. Upon the fulfillment (as determined by each Applicable Lender acting reasonably) (or waiver) of the conditions precedent set forth in Section 3 hereof in respect of the Applicable Aircraft, each such Lender shall instruct WFB to disburse the Deposit for application of its Commitment for such Aircraft.

(d) Postponement of Scheduled Delivery Date.

(1) Borrower may in the case of each Aircraft change or postpone (to a specified date not later than the Commitment Termination Date) the Scheduled Delivery Date for such Aircraft by telephonic notice (to be confirmed promptly in writing) to each Applicable Lender, provided such notice (specifying the new Delivery Date, if any) is received by such Lenders not later than 4:30 p.m. on such Scheduled Delivery Date being postponed (the “Postponement Notice”). If the revised Scheduled Delivery Date specified in the Postponement Notice is a date after a date specified in clause (x) or (z) of the definition of “Cutoff Date” set forth in Section 2.2(d)(4) hereof, then such revised Scheduled Delivery Date shall be deemed the “Scheduled Delivery Date” for such Aircraft for all purposes of the Applicable Operative Agreements.

(2) If the Scheduled Delivery Date for an Aircraft is postponed and the Deposit has been paid by the Lenders into the Account, then the Deposit for such Aircraft will, pending any return contemplated by Section 2.2(d)(4) below, be invested, together with earnings thereon, and reinvested by WFB at the sole direction, for the account, and at the risk of Borrower in an overnight investment selected by Borrower and acceptable to WFB (acting reasonably and in good faith). Upon Borrower’s oral (to be confirmed in writing) instructions, earnings on any such investments shall be applied to Borrower’s payment obligations to each Lender under Section 2.2(d)(3)(ii) to the extent of such earnings.

(3) If the Scheduled Delivery Date for an Aircraft is postponed and the Deposit has been paid by the Lenders into the Account, then Borrower shall pay interest hereunder to each Lender on the amount of its Deposit for the period from and including the original Scheduled Delivery Date for such Aircraft to but excluding the earlier of (i) the actual Delivery Date for such Aircraft, (ii) the

Cutoff Date (as defined below) or (iii) the date of return of the Deposit to such Lender pursuant to clause (4) below if such amounts are received by such Lender before 11:00 a.m. on such date (and if such amounts are received by such Lender after 11:00 a.m., the next succeeding Business Day). For each Lender, such interest shall accrue on the amount of such Lender’s Deposit at the applicable Debt Rate. Interest on the Deposit accrued pursuant to the preceding sentence shall (i) if accrued to the Delivery Date for such Aircraft, be paid on the first Payment Date following such delivery and (ii) if accrued to the Cutoff Date, be due and payable to each Lender on such date.

(4) If for any reason, other than the failure of any Lender to comply with the terms hereof, the Scheduled Delivery Date for an Aircraft is postponed beyond the earliest of (x) three Business Days after the Scheduled Delivery Date for such Aircraft, (y) the Commitment Termination Date or (z) such earlier date as Borrower shall specify (the “Cutoff Date”), then each such Lender shall cancel, terminate or otherwise unwind its funding arrangements made in the London interbank market or otherwise to fund its Commitment on the Scheduled Delivery Date for such Aircraft, and such Lender shall notify WFB thereof, and WFB shall return its Commitment for such Aircraft to it, subject, however, to such Lender’s continuing commitment to fund as provided herein.

(5) In the event of the occurrence of the events described in Section 2.2(c) or clause (4) above, Borrower agrees to pay each Lender promptly (but in any event within three (3) Business Days of the relevant Cutoff Date) (i) as compensation for the cancellation or termination of its Commitment for any Aircraft, an amount of liquidated damages equal to any loss incurred in connection with the unwinding or liquidating of any deposits or funding or financing arrangement with its funding source and (ii) without duplication of the amounts covered by the preceding clause (i) or to be paid pursuant to Section 4.1 hereof, the reasonable out-of-pocket costs and expenses of such Lender (including, without limitation, reasonable legal costs and expenses) incurred by such Lender in respect of such cancellation or termination to the extent described in the definition of Transaction Expenses.

(e) Prospective International Interest. Prior to the Scheduled Delivery Date of any Aircraft, a Prospective International Interest in the Airframe and each Engine relating to such Aircraft in the name of the Applicable Mortgagee shall have been duly registered on the International Registry with respect to the Mortgage with respect to such Airframe and Engines.

2.3

Terms of Repayment.

(1) On each Payment Date, Borrower shall make payments to the Applicable Mortgagee on each Applicable Equipment Note of principal scheduled to be paid thereon on such date in accordance with the amortization schedule attached thereto and accrued interest due and payable on such Equipment Note on such date. The amortization schedules in the aggregate determined for all

Applicable Equipment Notes issued in respect of any Aircraft shall be calculated by reference to Schedule 5A (if winglets are financed) or Schedule 5B (if winglets are financed) attached hereto. In respect of the amortization schedule for any particular Equipment Note issued in respect of any Aircraft, the payments due on any Payment Date set forth on such amortization schedule shall be pro rated based on the ratio by which the Original Amount of such Equipment Note bears to the aggregate Original Amount of all of the Applicable Equipment Notes. For the avoidance of doubt, the aggregate principal amount payable at any time under all Equipment Notes issued in respect of a single Aircraft shall be equal to the amount which would be required to be paid had a single Equipment Note complying with the requirements of this Section 2.3(1) been issued.

Interest on each Applicable Equipment Note will accrue at the Debt Rate for such Equipment Note (calculated on the basis of a year of 360 days and actual number of days elapsed), and be payable on each Payment Date. The interest payable on each Payment Date for any Applicable Equipment Note shall include interest accrued during the Interest Period ending on such Payment Date.

(2) Except as otherwise provided in the Applicable Mortgage, each payment of principal and interest received by the Applicable Mortgagee in respect of an Applicable Equipment Note shall be applied: first, to pay amounts due hereunder or under the Applicable Mortgage other than as specified in the following clauses, second, to pay accrued interest on such Applicable Equipment Note (as well as any interest on any overdue amount) to the date of such payment, third, to pay the principal of such Applicable Equipment Note then due, and fourth, the balance, if any, remaining thereafter, to pay installments of the principal of such Applicable Equipment Note remaining unpaid in the inverse order of their maturity.

2.4

Closing; Funds; No Set-Off.

(a) Location. Each closing of the Transactions shall take place on the Applicable Closing Date at the offices of Smith, Gambrell & Russell, LLP, Promenade II, Suite 3100, 1230 Peachtree Street, N.E., Atlanta, Georgia 30309 (the “Closing”), with a set of Operative Agreements relating to such Closing also being delivered in New York City, New York.

(b) Funds; No Set-Off. All payments by Borrower pursuant to this Section 2 and on any Equipment Note whether on account of principal, interest, LIBOR Breakage Amount, fees or otherwise shall be made in immediately available funds without set-off, counterclaim or defense to the account of the Applicable Mortgagee as set forth in Schedule 1 hereto.

2.5

Events of Default.

If an Event of Default as defined in any Mortgage (or, prior to the date of execution and delivery of any Mortgage, the form of Mortgage attached hereto as Exhibit A) shall have

occurred and be continuing, Lenders holding a majority of the Commitments in respect of any Aircraft may, by written notice to Borrower, cancel such Commitments, and upon such notice, such Commitments shall be cancelled and of no further effect. If an Event of Default under Section 5.1(e), (f) or (g) under any Mortgage (or form of Mortgage) shall have occurred and be continuing, the Commitments shall automatically, without any action or notice, be cancelled and of no further effect.

2.6

No Winglet Notice; Post-Closing Winglet Funding.

(a) No Winglet Notice. In respect of any Aircraft, at any time (but in no event later than five (5) Business Days prior to the Scheduled Delivery Date in respect of such Aircraft) Borrower may deliver written notice to the Applicable Lenders of Borrower’s intent not to finance the acquisition of winglets for installation on such Aircraft (the “No Winglet Notice”), in which case the Commitment for such Aircraft shall be adjusted as provided in Schedule 2 hereof and if such notice shall specify that such Commitment is to be permanently reduced, the Commitment Fee from and after the date on which the Applicable Lenders receive such notice shall be calculated based on the adjusted Commitment for such Aircraft. The Borrower shall furnish the No Winglet Notice if the Applicable Aircraft does not have installed thereon winglets.

(b) Post-Closing Winglet Funding. If, in respect of any Aircraft, Borrower delivers a No Winglet Notice (which did not specify a permanent reduction of Commitment) and, within six (6) months following the Applicable Closing Date, installs winglets on such Aircraft, the Applicable Lenders shall, subject to the terms of this Section 2.6(b), make an additional secured loan (pro rata according to the respective Commitment of the Applicable Lenders in respect of such Aircraft) in an amount equal to the Winglet Amount upon five (5) Business Days’ irrevocable written notice from Borrower requesting such additional secured loan (the “Winglet Loan Request”). A Winglet Loan Request may not be issued later than one (1) month following the installation of the related winglets and shall certify that winglets have bee installed on the Applicable Aircraft. Interest on the Winglet Amount will accrue at the Special Debt Rate (calculated on the basis of a year of 360 days and actual number of days elapsed) from and after the date the Applicable Lenders make the additional secured loan under this Section 2.6(b) to but excluding the first Payment Date following the making of such additional secured loan, which interest will be payable on such first Payment Date. From and after such first Payment Date, the principal payment amounts set forth on the amortization schedules to the Equipment Notes in respect of such Aircraft shall be adjusted upwards on a pro rata basis to reflect an Original Amount equal to the Lender’s respective Commitments as provided in Schedule 2 hereof calculated as though Schedule 5A governed such Equipment Notes. In connection with any borrowing of the Winglet Amount pursuant to this Section 2.6(b) and as a condition thereto, Borrower shall deliver to each Applicable Lender an allonge duly executed and delivered by Borrower to such Lender’s Equipment Note evidencing the lending of the Winglet Amount (or pro rata share thereof) by such Lender, the interest rate thereon and the amortization thereof (or, at the Applicable Lender’s request, its Equipment Note shall be appropriately amended and restated to take into account the Winglet Amount loan). The Winglet Amount associated with any Aircraft may not be borrowed if (x) the related Equipment Notes

have been prepaid or (y) an Event of Default has occurred and is continuing. If for any reason, other than the failure of any Lender to comply with the terms hereof, a loan in respect of a Winglet Amount is not made on the date indicated in the Winglet Loan Request, Borrower agrees to indemnify each Lender on demand for any damages associated with the unwinding or liquidation of deposits or funding or financing arrangements with its funding source. At such time as any Lender shall advance the Winglet Amount (or pro rated amount thereof) associated with any Aircraft as provided in this Section 2.6(b), Borrower shall pay to such Lender the up-front fee associated with such advance as provided in the Upfront Fee Letter.

Borrower agrees to pay a Commitment Fee on account of the unutilized Commitment for each Aircraft to the Applicable Mortgagee in arrears on the last Business Day of each calendar quarter following the date of this Agreement, on the Closing Date for such Aircraft and, if not theretofore utilized, on the Commitment Termination Date. Such Commitment Fee shall be calculated on the basis of a year of 360 days and actual number of days elapsed and shall accrue from the date of this Agreement until the earlier of, for any such Aircraft, its Closing Date and the Commitment Termination Date.

4.4

Increased Costs/Capital Adequacy

(a) Borrower shall pay directly to each Lender from time to time such amounts as such Lender may determine to be necessary to compensate such Lender for any increase in costs that such Lender determines are attributable to its making or maintaining of its Commitment or the loans evidenced by its Equipment Notes or funding arrangements utilized in connection with such loans, or any reduction in any amount receivable by such Lender hereunder in respect of any of Commitments, such loans or such arrangements (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), in either case applicable to the period commencing sixty (60) days prior to Lender’s notification thereof pursuant to Section 4.4(c) and resulting from any Regulatory Change that:

(1) imposes any tax that is the functional equivalent of any reserve, special deposit or similar requirement of the sort covered by clause (2) below; or

(2) imposes or modifies any reserve, special deposit or similar requirements (including any Reserve Requirement) relating to any extensions of credit or other assets of, or any deposits with or other liabilities of, such Lender, or any such obligations; or

(3) imposes any other condition affecting this Agreement or its Equipment Notes (or any of such extensions of credit or liabilities) or any such obligation.

(b) Without limiting the effect of the foregoing provisions of this Section 4.4 (but without duplication), Borrower shall pay directly to each Lender from time to time on request such amounts as such Lender shall determine to be necessary to compensate such Lender (or, without duplication, the holding company of which such Lender is a

subsidiary) for any increase in costs that are attributable to the maintenance by such Lender (or any lending office or such holding company), pursuant to any law or regulation or any interpretation, directive or request (whether or not having the force of law and whether or not failure to comply therewith would be unlawful so long as compliance therewith is standard banking practice in the relevant jurisdiction) of any court or governmental or monetary authority following (i) any Regulatory Change or (ii) implementing any risk-based capital guideline or other similar requirement issued by any government or governmental or supervisory authority at the national level (including the implementation of the capital guidelines commonly known as Basle II), of capital in respect of its Commitments or Equipment Notes or funding arrangements utilized in connection with the Equipment Notes. Such compensation shall include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Lender (or any lending office or such bank holding company) would have achieved but for such law, regulation, interpretation, directive or request, but shall be limited to any such increase in costs or reductions attributable for the period commencing sixty (60) days prior to Lender’s notification thereof pursuant to Section 4.4(c).

(c) Each Lender shall notify Borrower of any event occurring after the date of this Agreement entitling such Lender to compensation under paragraph (a) or (b) of this Section 4.4 as promptly as practicable following its actual knowledge thereof. Each Lender will use commercially reasonable efforts (at Borrower’s expense) to attempt to mitigate the amount of the Additional Costs associated with such event, including designating a different lending office for the Equipment Notes of such Lender affected by such event if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the opinion of such Lender, result in any economic, legal or regulatory disadvantage to such Lender (other than economic disadvantages for which Borrower agrees to indemnify such Lender and which indemnity is acceptable to such Lender in its discretion acting reasonably and in good faith based on its credit assessment of Borrower). If after using commercially reasonably efforts as aforesaid such Lender is not able to mitigate the amount of or the need for such compensation to the reasonable satisfaction of Borrower within thirty (30) days of such Lender’s notice described in Section 4.4(c) hereof, Borrower may prepay in accordance with Section 2.10 of the Applicable Mortgage the unpaid Original Amount of the affected Equipment Notes plus interest accrued thereon and any LIBOR Breakage Amount. Each Lender will furnish to Borrower an officer’s certificate setting forth in reasonable detail (i) the events giving rise to such Additional Costs, (ii) the basis for determining and allocating such Additional Costs and (iii) the amount of each request by such Lender for compensation under paragraph (a) or (b) of this Section 4.4 (subject, however, to any limitations such Lender may require in respect of disclosure of confidential information relating to its capital structure), together with a statement that the determinations and allocations made in respect of the Additional Costs comply with the provisions of this Section 4.4, including as provided in the last sentence of this paragraph (c). Determinations and allocations by any Lender for purposes of this Section 4.4 of the effect of any Regulatory Change pursuant to paragraph (a) of this Section 4.4, or of the effect of capital maintained pursuant to paragraph (b) of this Section 4.4, on its costs or rate of return of maintaining Equipment Notes or its funding, or on amounts receivable by it in respect of Equipment Notes, and of the amounts required to compensate such Lender under this Section 4.4, shall be conclusive, absent manifest error; provided, that such determinations and allocations are made on a reasonable basis and, in the case of allocations, are made fairly.

(d) Borrower shall not be required to make payments under this Section to any Lender if (i) a claim hereunder arises through circumstances peculiar to such Lender and which do not affect commercial banks in the same jurisdiction generally or (ii) the claim arises out of a relocation by such Lender of its lending office (except any such relocation effected pursuant to Section 4.4(c)), or (iii) such Lender is not seeking similar compensation for such costs from its borrowers similarly situated with Borrower and commercial aircraft loans generally, or (iv) the claim arises as the result of any law or regulation or any interpretation, directive or request of any court or governmental or monetary authority in any jurisdiction other than an Accepted Jurisdiction, unless, in the case of Section 4.4(d)(iv), such claim is made by a Lender that is a United States branch of a foreign commercial bank that has its principal place of business in a country that is a member of the Organization for Economic Co-operation and Development as of the date of this Agreement.

In connection with any such Junior Loan, each of the parties hereto (or their successors) and the lender(s) providing such Junior Loan (and the related mortgagee) will execute and deliver an intercreditor agreement in form and substance reasonably satisfactory to the parties hereto (or their successors) and the lender(s) providing such Junior Loan, which agreement shall, among other things, ensure there is no diminution of the Applicable Mortgagee’s priority and perfected Lien in such Aircraft and all other then-existing Collateral (as defined in the Applicable Mortgage). In connection with any such Junior Loan the security and credit position of the Applicable Lenders will not be adversely affected and the rights of the holders of the Junior Loans vis a vis the Applicable Lenders will be limited to any buyout right that would cover outstanding principal, accrued interest, any LIBOR Breakage Amount and all other amounts due and owing to the applicable Lenders under the Applicable Operative Agreements (the “Applicable Senior Debt”). In addition the holders of the Junior Loan will (i) fully subordinate the entirety of their claims to the Applicable Senior Debt as it relates to the Collateral and (ii) not be entitled to exercise any remedies against the Applicable Aircraft and related Collateral so long as the Applicable Senior Debt is outstanding. Borrower shall reimburse the Applicable Mortgagee and the Lenders for all of their reasonable out-of-pocket fees and expenses (including

reasonable fees and disbursements of counsel) incurred in connection with documenting any such Junior Loan and intercreditor agreement, and with respect to any Junior Loan that is consummated after the Applicable Closing Date, Borrower shall pay to the Applicable Mortgagee the Working Fee to be distributed by the Applicable Mortgagee to the Applicable Lenders as directed by the Applicable Lenders.

7.4

Sale-Leaseback Transaction.

Notwithstanding anything to the contrary in any Operative Agreement, upon not less than thirty (30) days’ prior written notice to the parties hereto (the “Sale-Leaseback Notice”), Borrower shall, so long as no Event of Default is then in existence, have the right to sell, at any time prior to the first (1^st) anniversary of the Applicable Closing Date, an Aircraft and transfer title to such Aircraft to an owner trustee for the benefit of an owner participant in a transaction in which such owner trustee assumes all of Borrower’s obligations under the Applicable Equipment Notes and the Applicable Mortgage on a non-recourse basis (with Borrower being released from such obligations, except to the extent accrued before the assumption), leases such Aircraft to Borrower, and assigns such lease to the Applicable Mortgagee pursuant to an amended and restated mortgage (a “Sale-Leaseback”). In connection with such Sale-Leaseback, each of the relevant parties hereto (or their successors) will execute and deliver appropriate documentation permitting the owner trustee to assume Borrower’s obligations under the Applicable Equipment Notes and the Applicable Mortgage on a non-recourse basis, releasing Borrower from all obligations in respect of such Equipment Notes and Mortgage (except to the extent accrued before the assumption), and take all other actions as are reasonably necessary to permit such assumption by the owner trustee. Such Sale-Leaseback shall be subject to the satisfaction of the following terms and conditions:

(a) the Sale-Leaseback Notice shall identify the owner participant and the owner trustee;

(b) the identified owner participant shall have a tangible net worth of at least $50,000,000 per Aircraft subject to the Sale-Leaseback (or have its obligations guaranteed by a Person with such a tangible net worth level) and the owner participant shall be an entity regularly participating in the leasing and financing of equipment or shall otherwise be reasonably acceptable to the Applicable Lenders; and

(c) documentation for such transaction shall be in form and substance reasonably satisfactory to the Applicable Lenders, Borrower, the owner participant and the owner trustee and shall:

(1) other than variations necessary to effect the Sale-Leaseback, contain terms and conditions concerning Borrower and the Applicable Aircraft no less favorable to the Applicable Lenders than those binding on Borrower and such Aircraft contained in the Applicable Operative Agreements;

(2) the applicable lease shall be a “hell-or-highwater” triple net lease, with a minimum rents clause that will provide that basic rent shall always be sufficient to pay debt service on the Applicable Equipment Notes, and that the

termination/stipulated loss value shall always be sufficient to pay the aggregate outstanding principal amount of, and accrued interest on, the Applicable Equipment Notes;

(3) contain debt/equity provisions as are consistent with market practice and satisfactory to the Applicable Lenders, but shall not, without the consent of the Applicable Lenders, contain any breakage cap or other limitation relating to any funding transaction (whether relating to the distribution-of-proceeds waterfall following an “event of default” or the owner participant’s buy-out right following an “event of default”) or otherwise adversely affect the ability of the Applicable Lenders to recover any LIBOR Breakage Amounts ahead of recoveries by the owner participant of its investment; the Applicable Lenders agree to negotiate such debt/equity provisions in good faith, provided that, in no event will the Applicable Lenders be required to agree to (A) payment cure rights that would forestall their ability to take action for more than one year; or (B) equity squeeze provisions that would prohibit the Applicable Lenders from squeezing out the equity following the 60-day Section 1110 period; and

(4) the economic substance (e.g., loan amount, interest rate, payment periodicity, payment conventions, maturity date, amortization profile, Debt Rate, etc.) of the Sale-Leaseback debt funded by the relevant Lenders shall be the same as that evidenced by the Applicable Equipment Notes.

Borrower shall reimburse the Applicable Mortgagee and the Applicable Lenders for all of their reasonable out-of-pocket fees and expenses (including reasonable fees and disbursements of counsel) incurred in connection with any such Sale-Leaseback, and with respect to any Sale-Leaseback that is consummated after the Applicable Closing Date, Borrower shall pay to the Applicable Mortgagee the Working Fee to be distributed by the Applicable Mortgagee to the Applicable Lenders as directed by the Applicable Lenders.

7.5

Termination of Cross-Collateralization and Cross-Defaults.

(a) Majority. If at any time a majority of the aggregate unpaid Original Amount of all Applicable Equipment Notes in respect of an Aircraft (for purposes of this Section 7.5(a) only, a “Relevant Aircraft”) ceases to be held by the one or more of the Initial Lenders, then (x) for purposes of the Mortgage entered into in respect of such Relevant Aircraft, the Equipment Notes issued, and the Mortgage entered into, in respect of the other Aircraft shall, without further action of the parties hereto or thereto, not be deemed to be “Related Equipment Notes” or a “Related Mortgage” (as the case may be) and (y) the Equipment Notes issued, and the Mortgage entered into, in respect of such Relevant Aircraft shall, without further act of the parties hereto or thereto, not be deemed to be “Related Equipment Notes” or a “Related Mortgage” (as the case may be) under the Mortgage in respect of the other Aircraft.

(b) Sale-Leaseback. If an Aircraft is subjected to a Sale-Leaseback pursuant to Section 7.4 (for purposes of this Section 7.5(b) only, the “Relevant Aircraft”) then (x) for purposes of the Mortgage entered into in respect of such Relevant Aircraft, the

Equipment Notes issued, and the Mortgage entered into, in respect of the Aircraft not subjected to a Sale-Leaseback with the same (or affiliated) owner participants (for purposes of this Section 7.5(b) only, the “No-Cross Aircraft”) shall, without further act of the parties hereto or thereto, no longer be deemed to be “Related Equipment Notes” or a “Related Mortgage” (as the case may be) and (y) the Equipment Notes issued, and the Mortgage entered into, in respect of such Relevant Aircraft shall, without further act of the parties hereto or thereto, no longer be deemed to be “Related Equipment Notes” or a “Related Mortgage” (as the case may be) for purposes the Mortgage in respect of the No-Cross Aircraft.

(c) Payment. If the unpaid Original Amount of (plus the unpaid and accrued interest thereon and all other amounts due under the Applicable Operative Agreements with respect to) all Equipment Notes in respect of an Aircraft (for purposes of this Section 7.5(c) only, the “Relevant Aircraft”) are paid in full and the Lien of the Applicable Mortgage is discharged and terminated in accordance with the terms thereof, then (x) for purposes of the Mortgage entered into in respect of such Relevant Aircraft, the Equipment Notes issued, and the Mortgage entered into, in respect of the other Aircraft shall, without further act of the parties hereto or thereto, no longer be deemed to be “Related Equipment Notes” or a “Related Mortgage” (as the case may be) and (y) the Equipment Notes issued, and the Mortgage entered into, in respect of such Relevant Aircraft shall, without further act of the parties hereto or thereto, no longer be deemed to be “Related Equipment Notes” or a “Related Mortgage” (as the case may be) for purposes of the Mortgage in respect of such other Aircraft; provided that if the Equipment Notes issued in connection with any Applicable Aircraft have been paid in full as aforesaid as a consequence of the foreclosure sale on such Aircraft during the continuation of an Event of Default, the excess proceeds of the sale of such Aircraft (i.e., the proceeds remaining after application of the proceeds of such sale against the amounts outstanding to the Applicable Lender(s) holding Equipment Notes in respect of such Aircraft) shall be, as contemplated by Section 3.3 of the Applicable Mortgage, available to be applied against the amounts outstanding to the Applicable Lenders holding Equipment Notes issued in respect of the other Aircraft.

8. CONFIDENTIALITY

Each Lender, Borrower and WFB (in its individual capacity and as a Mortgagee) shall keep confidential the terms of Annex B to each Mortgage and all information furnished to them from time to time hereunder or under the Mortgage (which is marked confidential) and shall not disclose, or cause to be disclosed, the same to any Person, except (a) to prospective and permitted transferees of the interests of any Lender, WFB (in its individual capacity or as a Mortgagee) or their counsel, independent insurance brokers, auditors, or other agents who are under an obligation of confidentiality with respect to such information or who otherwise agree to hold such information confidential, (b) to any Lender’s, Borrower’s or WFB’s counsel, independent insurance brokers, auditors, or other agents, Affiliates, or investors who agree to hold such information confidential, (c) as may be required by any statute, court, or administrative order or decree, legal process, or governmental ruling or regulation, including those of any applicable regulatory authority, federal or state banking examiners, taxing authorities, or any stock exchange, or (d) to such other Persons as are reasonably deemed necessary by the

disclosing party in order to protect the interests of such party or for the purposes of enforcing such documents by such party; provided, that any and all disclosures permitted by clauses (c) and (d) above shall be made only to the extent reasonably deemed necessary to meet the specific requirements or needs of the Persons making such disclosures.

9. INDEMNIFICATION AND EXPENSES

9.1

General Indemnity.

(a) Indemnity. Whether or not any of the Transactions are consummated, Borrower shall indemnify, protect, defend, and hold harmless each Indemnitee from, against, and in respect of, and shall pay on an After-Tax Basis, any and all Expenses of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against any Indemnitee, relating to, resulting from, or arising out of or in connection with any one or more of the following:

(b) Exceptions. Notwithstanding anything in Section 9.1(a), Borrower shall not be required to indemnify, protect, defend or hold harmless any Indemnitee pursuant to Section 9.1(a) against any Expense of such Indemnitee:

(1)

for any Taxes or a loss of Tax benefit, whether or not Borrower is required to indemnify therefor pursuant to Section 9.3;

(2)

to the extent attributable to any Transfer (voluntary or involuntary) by or on behalf of such Indemnitee of any Equipment Note or interest therein, except for out-of-pocket costs and expenses incurred as a result of any such Transfer requested in writing by Borrower or made or effected pursuant to the exercise of remedies under any Operative Agreement;

(3)

to the extent attributable to the gross negligence or willful misconduct of such Indemnitee or any “Related Indemnitee” (as defined at the end of this Section 9.1(b)) (other than gross negligence or willful misconduct imputed to such Person solely by reason of its interest in the Aircraft or any Operative Agreement);

(4)

to the extent attributable to the incorrectness or breach of any representation or warranty, of such Indemnitee or any Related Indemnitee, contained in or made pursuant to any Operative Agreement;

(5)

to the extent attributable to the failure, by such Indemnitee or any Related Indemnitee, to perform or observe any agreement, covenant, or condition on its part to be performed or observed in any Operative Agreement;

(6)

to the extent attributable to the offer or sale, by such Indemnitee or any Related Indemnitee, of any interest in the Equipment Notes, or any similar interest, in violation of the Securities Act or other applicable federal, state, or foreign securities Laws (other than any thereof caused by acts or omissions of Borrower);

(7)

(aa) with respect to any Indemnitee other than the Mortgagee, to the extent attributable to such Mortgagee’s failure to distribute funds received and distributable by it in accordance with the relevant Mortgage and (bb) with respect to the Mortgagee, to the extent attributable to its negligence or willful misconduct in the distribution of funds received and distributable by it in accordance with the relevant Mortgage;

(8)

other than during the existence of an Event of Default, to the extent attributable to the authorization or giving or withholding of any future amendments, supplements, waivers, or consents with respect to any Operative Agreement, other than any requested by Borrower or required by or made pursuant to the terms of the Operative Agreements (unless such requirement results from the actions of an Indemnitee not required by or made pursuant to the Operative Agreements);

(9)

to the extent attributable to any amount which any Indemnitee expressly agrees to pay (other than amounts required to be paid by such Indemnitee in connection with the enforcement of its rights and remedies hereunder and under any Operative Agreement) or such Indemnitee expressly agrees shall not be paid by or be reimbursed by Borrower;

(10)

to the extent that it is an ordinary and usual operating or overhead expense;

(11)

for any Lien attributable to such Indemnitee or any Related Indemnitee that Borrower is not obligated to discharge under the Operative Agreements;

if another provision of an Operative Agreement specifies the extent of Borrower’s responsibility or obligation with respect to such Expense, to the extent arising from a cause other than Borrower’s failure to comply with such specified responsibility or obligation; or

(13)

to the extent incurred by or asserted against an Indemnitee as a result of any “prohibited transaction” caused by it, within the meaning of ERISA § 406 or Code § 4975(c)(1).

For purposes of this Section 9.1, a Person shall be considered a “Related Indemnitee” of an Indemnitee if that Person is an Affiliate or employer of such Indemnitee, a director, officer, employee, agent, or servant of such Indemnitee or any such Affiliate, or a successor or permitted assign of any of the foregoing (other than pursuant to a Transfer). For the avoidance of doubt, no Transferee of an Equipment Note shall be entitled under this Section 9.1 to be indemnified, protected, defended or held harmless against any Expense to the extent that any prior holder of such Equipment Note would not have been entitled to such rights and protections at the time of its transfer.

(c) Separate Agreement. The provisions of this Section 9.1 constitute a separate agreement with respect to each Indemnitee and is enforceable directly by each such Indemnitee.

(d) Notice. If an Indemnitee makes a claim for any Expense indemnifiable under this Section 9.1, such Indemnitee shall give prompt written notice thereof to Borrower. Notwithstanding the foregoing, any Indemnitee’s failure to notify Borrower as provided in this Section 9.1(d), or in Section 9.1(e), shall not release Borrower from any of its obligations to indemnify such Indemnitee hereunder, except to the extent that such failure results in an additional Expense to Borrower (in which event Borrower shall not be responsible for such additional Expense) or materially impairs Borrower’s ability to contest such claim.

(e) Notice of Proceedings; Defense of Claims; Limitations.

(1) If any action, suit, or proceeding for which Borrower is responsible under this Section 9.1 is brought against any Indemnitee, such Indemnitee shall notify Borrower of the commencement thereof, and Borrower may, at its expense, participate in and, to the extent that it so desires (subject to the provisions of the following paragraph), assume and control the defense thereof and, subject to Section 9.1(e)(3), settle or compromise it.

(2) Borrower or its insurer(s) shall have the right, at its or their expense, to investigate and control the defense of, any action, suit, or proceeding, relating to any Expense for which indemnification is sought pursuant to this Section 9.1, and each Indemnitee shall cooperate reasonably and in good faith with Borrower or its insurer(s) with respect thereto; provided, that Borrower shall not be entitled to control the defense of any such action, suit, or proceeding, or to compromise any such Expense, while (a) any Event of Default exists, (b) if such proceedings will involve a material risk of the sale, forfeiture, or loss of, or the creation of any Lien (other than Permitted Lien) on the Aircraft, or the Collateral, unless Borrower shall have posted a bond or other security or collateral reasonably satisfactory to such Indemnitee in respect to such risk, or (c) if such proceedings entail any material risk of criminal liability or material civil liability. In connection with any such Borrower-controlled action, suit, or proceeding, such Indemnitee shall have the right to participate therein, at its sole cost and expense, with counsel reasonably satisfactory to Borrower, provided that such Indemnitee’s participation does not, in the reasonable opinion of the independent counsel appointed by Borrower or its insurers to conduct such proceedings, interfere with the defense of such case. In connection with any Indemnitee-controlled action, suit, or proceeding, Borrower or its insurers shall have the right to participate therein, at its or their sole cost and expense, with counsel reasonably satisfactory to any such Indemnitee, provided that Borrower’s or its insurers’ participation does not, in the reasonable opinion of the independent counsel appointed by any such Indemnitee to conduct such suit or proceedings, materially interfere with the defense of such case.

(3) In no event shall any Indemnitee enter into a settlement or other compromise with respect to any Expense without Borrower’s prior written consent (which shall not be unreasonably withheld or delayed), unless such Indemnitee waives its right to be indemnified with respect to such Expense under this Section 9.1.

(4) To the extent that any Expense indemnified by Borrower hereunder may be covered by insurance maintained by Borrower, at Borrower’s expense, each Indemnitee agrees to cooperate with the insurers in the exercise of their rights to investigate, defend, or compromise such Expense as may be required to retain the benefits of such insurance with respect to such Expense.

(5) If an Indemnitee is not a party to this Agreement, Borrower may require such Indemnitee to agree in writing to the terms of this Section 9.1 and Section 11.8 before making any payment to such Indemnitee under this Section 9.

(6) Nothing in this Section 9.1(e) shall require an Indemnitee to contest any Expense or to assume responsibility for or control of any judicial proceeding with respect thereto.

(f) Information. Borrower will provide the relevant Indemnitee with such information not within the control of such Indemnitee (but in Borrower’s control or

reasonably available to Borrower) which such Indemnitee reasonably requests, and will otherwise cooperate with such Indemnitee so as to enable such Indemnitee to fulfill its obligations under Section 9.1(e). The Indemnitee shall supply Borrower with such information not within the control of Borrower (but in such Indemnitee’s control or reasonably available to such Indemnitee) which Borrower reasonably requests to control or participate in any proceeding to the extent permitted by Section 9.1(e).

(g) Effect of Other Indemnities. Upon payment in full by or on behalf of Borrower of any indemnity provided for under this Agreement, Borrower, without any further action and to the full extent permitted by Law, will be subrogated to all rights and remedies of the Person indemnified (other than with respect to any of such Indemnitee’s insurance policies or in connection with any indemnity claim of such Indemnitee under Section 6.3 of the applicable Mortgage) in respect of the matter as to which such indemnity was paid. Each Indemnitee will give such further assurances or agreements and cooperate with Borrower to permit Borrower to pursue such claims, to the extent reasonably requested by Borrower and at Borrower’s expense.

(h) Refunds. If an Indemnitee receives any refund, in whole or in part, with respect to any Expense paid by Borrower hereunder, that Indemnitee will promptly pay the amount refunded (but not an amount in excess of the amount Borrower or any of its insurers has paid in respect of such Expense) over to Borrower unless a Special Default or Event of Default exists, in which case such amount shall be paid over to the relevant Mortgagee to hold as security for Borrower’s obligations under the relevant Operative Agreements or, if requested by Borrower, applied to satisfy those obligations.

9.2

Expenses.

Borrower shall pay (a) the ongoing fees and expenses of the Mortgagees, and (b) all reasonable out-of-pocket costs and expenses (including the reasonable fees and disbursements of counsel) incurred by the Mortgagees or Lenders attributable to an Event of Default or any waiver, amendment, or modification of any Operative Agreement to the extent requested by Borrower.

9.3

General Tax Indemnity.

(a) Withholding Taxes. Except as provided in Section 9.3(c), Borrower agrees that each payment paid by Borrower or the Mortgagee under the Equipment Notes, and any other payment or indemnity paid by Borrower or the Mortgagee to or for the benefit of a Lender under any Operative Agreement, shall be free of all withholdings or deductions with respect to Taxes of any nature unless the withholding or deduction is required by applicable Law, and if Borrower or the Mortgagee is required by applicable Law to make any such withholding or deduction for any such payment, (1) Borrower shall (or cause Mortgagee on its behalf to) make all such withholdings or deductions, (2) if and to the extent that all or any portion of the required withholdings or deductions constitutes Indemnified Withholding Taxes, the amount payable by Borrower shall be increased by Borrower so that, after the Mortgagee makes all required withholdings or deductions, such Lender receives the same amount that it would have received had no

such withholdings or deductions with respect to such Indemnified Withholding Taxes been made, with the amount payable by Borrower with respect to such Indemnified Withholding Taxes being calculated on an After-Tax Basis and (3) Borrower shall (or cause Mortgagee on its behalf to) pay the full amount withheld or deducted to the relevant Taxing Authority in accordance with applicable Law. The term “Indemnified Withholding Taxes” shall mean, with respect to any Equipment Note or other payment or indemnity paid by Borrower or the Mortgagee to or for the benefit of a Lender under any Operative Agreement, withholding taxes imposed by the U.S. Government, but only to the extent that, as the result of a change in law or regulation or the interpretation thereof or a change in a tax treaty to which the United States is a party, in each case that occurs after the Closing Date applicable to such Equipment Notes or other payment or indemnity paid by Borrower or the Mortgagee to or for the benefit of a Lender under any Operative Agreement, such withholding taxes become applicable with respect to a payment by Borrower or the Mortgagee to or for the benefit of the Lender (if none had previously been imposed or required) or the rate applicable to a previously imposed or required withholding tax is increased; provided that, if the particular Lender is based in a jurisdiction other than an Accepted Jurisdiction, the amount of Indemnified Withholding Taxes shall not exceed the amount of Indemnified Withholding Taxes that would be applicable if the Lender were based in an Accepted Jurisdiction or other jurisdiction to which such Equipment Notes have been transferred solely pursuant to this Section 9.3(a). In the event that Indemnified Withholding Taxes become payable by Borrower as provided above, the Lender will, if possible, at Borrower’s cost and expense, and without any adverse consequences, transfer the Equipment Notes to another jurisdiction that is mutually acceptable to Borrower and such Lender so that either (1) no such Indemnified Withholding Taxes would be applicable to subsequent payments to or for the benefit of such Lender following such transfer (taking into account the provisions of Treas. Reg. § 1.881-3 and the limitation on benefits provisions of any applicable tax treaty) or (2) the rate of the Indemnified Withholding Taxes applicable to subsequent payments to such Lender following such transfer (taking into account the provisions of Treas. Reg. § 1.881-3 and the limitation on benefits provisions of any applicable tax treaty) would not exceed the rate of the Indemnified Withholding Taxes applicable to payments to such Lender prior to such transfer and the applicable change in law or regulation or the interpretation thereof or change in tax treaty.

(b) General Tax Indemnity. Except as provided in Section 9.3(c) and whether or not any of the transactions contemplated hereby are consummated, Borrower shall pay, indemnify, protect, defend, and hold harmless each Tax Indemnitee from all Taxes imposed by any Taxing Authority imposed on or asserted against any Tax Indemnitee or the Aircraft, the Airframe, any Engine, or any Part, or any interest in any of the foregoing (whether or not indemnified against by any other Person), upon or with respect to the Operative Agreements or the transactions or payments contemplated thereby, including any Tax imposed upon or with respect to (x) the Aircraft, the Airframe, any Engine, any Part, any Operative Agreement (including any Equipment Notes), any data, or any other thing delivered or to be delivered under an Operative Agreement, (y) the purchase, manufacture, acceptance, rejection, sale, transfer of title, return, ownership, mortgaging, delivery, transport, charter, rental, lease, re-lease, sublease, assignment, possession, repossession, presence, use, condition, storage, preparation, maintenance, modification,

alteration, improvement, operation, registration, transfer or change of registration, reregistration, repair, replacement, overhaul, location, control, imposition of any Lien, financing, refinancing requested by Borrower, abandonment, or other disposition of the Aircraft, the Airframe, any Engine, any Part, any data, or any other thing delivered or to be delivered under an Operative Agreement or (z) interest, fees, or other income, proceeds, receipts, or earnings, whether actual or deemed, arising upon, in connection with, or in respect of any of the Operative Agreements (including the property or income or other proceeds with respect to property held as part of the Collateral) or the transactions contemplated thereby.

(c) Certain Exceptions. The provisions of Section 9.3(a) and Section 9.3(b) shall not apply to, and Borrower shall have no liability hereunder for, Taxes:

(1) imposed on a Tax Indemnitee by the federal government of the United States or any Taxing Authority or governmental subdivision of the United States or therein (including any state or local Taxing Authority) (aa) on, based on, or measured by gross or net income or gross or net receipts, including capital gains taxes, excess profits taxes, minimum taxes from tax preferences, alternative minimum taxes, branch profits taxes, accumulated earnings taxes, personal holding company taxes, succession taxes and estate taxes, and any withholding taxes on, based on, or measured by gross or net income or receipts, or (bb) on, or with respect to, or measured by capital or net worth or in the nature of a franchise tax or a tax for the privilege of doing business (other than Indemnified Withholding Taxes, sales, use, rental, stamp, documentary, license, or property Taxes and value added Taxes (that are not imposed in direct substitution for an income Tax);

(2) imposed on a Tax Indemnitee by any Taxing Authority or governmental subdivision thereof or therein outside of the United States (including any Taxing Authority in or of a territory, possession or commonwealth of the United States) (aa) on, based on, or measured by gross or net income or gross or net receipts, including capital gains taxes, excess profits taxes, minimum taxes from tax preferences, alternative minimum taxes, branch profits taxes, accumulated earnings taxes, personal holding company taxes, succession taxes and estate taxes, and any withholding taxes on, based on, or measured by gross or net income or receipts, or (bb) on, or with respect to, or measured by capital or net worth or in the nature of a franchise tax or a tax for the privilege of doing business (other than, in the case of clause (aa) or (bb), (y) sales, use, rental, stamp, documentary, license, or property Taxes and value added Taxes (that are not imposed in direct substitution for an income Tax), or (z) any Taxes imposed by any Taxing Authority (other than a Taxing Authority within whose jurisdiction such Tax Indemnitee is incorporated or organized or maintains its principal place of business) if such Tax Indemnitee would not have been subject to Taxes of such type by such jurisdiction but for (i) the location, use, or operation of the Aircraft, the Airframe, any Engine, or any Part thereof by any Borrower Person within the jurisdiction of the Taxing Authority imposing such Tax, or (ii) the activities of any Borrower Person in such jurisdiction, including use of any other aircraft by

any Borrower Person in such jurisdiction, (iii) the status of any Borrower Person as a foreign entity or as an entity owned in whole or in part by foreign persons, (iv) any Borrower Person having made (or having been deemed to have made) payments to or for the benefit of such Tax Indemnitee from the relevant jurisdiction, or (v) any Borrower Person being incorporated or organized or maintaining a place of business or conducting activities in such jurisdiction);

(3) on, with respect to, or measured by any trustee fees, commissions, or compensation received by Mortgagee or WFB;

(4) that are being contested as provided in Section 9.3(e) below;

(5) imposed on any Tax Indemnitee to the extent that such Taxes result from the gross negligence or willful misconduct of such Tax Indemnitee or any Affiliate thereof;

(6) imposed on or with respect to a Tax Indemnitee (including a transferee thereof in those cases in which the Tax on transfer is imposed on, or is collected from, the transferee) as a result of a transfer or other disposition (including a deemed transfer or disposition) by such Tax Indemnitee or any of its Related Tax Indemnitees of any or all of its interest in the Aircraft, the Airframe, any Engine, or any Part, any interest arising under the Operative Agreements, or any Equipment Note, or as a result of a transfer or disposition (including a deemed transfer or disposition) of any interest in a Tax Indemnitee (other than (1) a substitution or replacement of the Aircraft, the Airframe, any Engine, or any Part by a Borrower Person that is treated for Tax purposes as a transfer or disposition, or (2) a transfer requested by Borrower or required by the Operative Agreements or pursuant to an exercise of remedies upon a then-existing Event of Default);

(7) in excess of those that would have been imposed had there not been a transfer or other disposition excluded from indemnification by clause (6) of this Section 9.3(c) by or to such Tax Indemnitee or any of its Related Tax Indemnitees;

(8) consisting of any interest, penalties, or additions to Tax imposed on a Tax Indemnitee as a result (in whole or in part) of a failure of such Tax Indemnitee or any of its Related Tax Indemnitees to properly and timely file any Tax return that it is required to file, unless such failure is caused by Borrower’s failure to fulfill its obligations (if any) under Section 9.3(g) with respect to such Tax return;

(9) resulting from, or that would not have been imposed but for, any Liens arising as a result of claims against, or acts or omissions of, or otherwise attributable to such Tax Indemnitee or any of its Related Tax Indemnitees that Borrower is not obligated to discharge under the Operative Agreements;

(10) imposed on a Tax Indemnitee as a result of the breach by such Tax Indemnitee or any of its Related Tax Indemnitees of any covenant of such Tax Indemnitee or any Affiliate thereof contained in any Operative Agreement or the inaccuracy of any representation or warranty by such Tax Indemnitee or any Affiliate thereof in any Operative Agreement;

(11) in the nature of an intangible or similar Tax imposed upon or with respect to the value or principal amount of the interest of a Lender in any Equipment Note or the loan evidenced thereby, but only if such Taxes are in the nature of franchise Taxes or result from the conduct of business by such Tax Indemnitee in the taxing jurisdiction and, in each case, are imposed because of the place of incorporation or the activities unrelated to the Transactions in the taxing jurisdiction of such Tax Indemnitee;

(12) imposed on a Tax Indemnitee by a Taxing Authority of a jurisdiction outside the United States, to the extent that such Taxes result from a connection between the Tax Indemnitee or any of its Related Tax Indemnitees and such jurisdiction imposing such Tax unrelated to the Transactions; or

(13) relating to ERISA or to Code § 4975.

For purposes of this Section 9.3, a Person shall be considered a “Related Tax Indemnitee” of a Tax Indemnitee if that Person is an Affiliate or employer of such Tax Indemnitee, a director, officer, employee, agent, or servant of such Tax Indemnitee or any such Affiliate, or a successor or permitted assign of any of the foregoing (other than pursuant to a Transfer).

(d) Payment.

(1) Borrower’s indemnity obligation to a Tax Indemnitee under this Section 9.3 shall equal the amount which, after taking into account any Tax currently payable upon the receipt or accrual of the amounts payable under this Section 9.3 and any current tax benefits realized by such Tax Indemnitee as a result of the indemnifiable Tax (including any benefits realized as a result of such Tax Indemnitee’s use of an indemnifiable Tax as a credit against Taxes not indemnifiable under this Section 9.3), shall equal the amount of the Tax indemnifiable under this Section 9.3.

(2) At Borrower’s written request, the computation of the amount of any indemnity payment owed by Borrower or any amount owed by a Tax Indemnitee to Borrower pursuant to this Section 9.3 shall be verified and certified by an independent public accounting firm selected by such Tax Indemnitee and reasonably satisfactory to Borrower. Each Tax Indemnitee shall upon written request provide to such accounting firm such information in such Tax Indemnitee’s possession or control as is reasonably necessary, for the performance of such verification (subject to the accounting firm’s execution and delivery of a confidentiality agreement in form and substance reasonably acceptable to the Tax Indemnitee. Such verification shall be binding on Borrower

and the Tax Indemnitee. The costs of such verification (including the fee of such public accounting firm) shall be borne by Borrower unless such verification results in an adjustment in Borrower’s favor of 5% or more of the net present value of the payment as computed by such Tax Indemnitee, in which case the costs shall be paid by such Tax Indemnitee.

(3) Each Tax Indemnitee shall provide Borrower with such certifications, and such information and documentation in such Tax Indemnitee’s possession or control, as Borrower reasonably requests in writing that are necessary to minimize any indemnity payment pursuant to this Section 9.3 and which such Tax Indemnitee can provide without incurring material adverse consequences under applicable Law, and Borrower shall, on written request from such Tax Indemnitee, reimburse such Tax Indemnitee for its reasonable out-of-pocket expenses incurred in providing such certifications, information and documentation to Borrower. If the Tax Indemnitee believes that providing to Borrower the certifications, information and documentation requested by Borrower would result in the incurrence of material adverse consequences under applicable Law, the Tax Indemnitee shall notify Borrower of the bases of that belief and the Tax Indemnitee and Borrower shall promptly meet to discuss the matter and, if Borrower and the Tax Indemnitee are unable to agree whether such material adverse consequences would result, shall appoint an independent accounting firm to resolve the issue on terms similar to those set forth in Section 9.3(d)(2) hereof (except that Borrower and the Tax Indemnitee shall share equally the costs of such accounting firm).

(4) Each Tax Indemnitee shall promptly forward to Borrower any written notice, bill, or advice that such Tax Indemnitee receives from any Taxing Authority concerning any Tax for which it seeks indemnification under this Section 9.3. Borrower shall pay any amount for which it is liable pursuant to this Section 9.3 directly to the appropriate Taxing Authority if legally permissible, or, upon written demand of a Tax Indemnitee, to such Tax Indemnitee within 30 days of such demand (or, if a contest occurs in accordance with Section 9.3(d), within 30 days after a Final Determination (as defined below)), but in no event more than three Business Days before the related Tax is due. If requested by a Tax Indemnitee in writing, Borrower shall furnish at its expense to the appropriate Tax Indemnitee the original or a certified copy of a receipt for Borrower’s payment of any Tax paid by Borrower (if such a receipt is reasonably obtainable from the applicable Taxing Authority), or such other evidence of payment of such Tax as is reasonably acceptable to such Tax Indemnitee. Borrower shall also furnish at its expense promptly upon written request such data as any Tax Indemnitee reasonably requires to enable such Tax Indemnitee to comply with the requirements of any taxing jurisdiction; provided that Borrower shall not be required to furnish such data if (x) such data are not within the possession or control of Borrower (unless Borrower is required to maintain such data pursuant to applicable Law) or (y) such data are not customarily furnished by U.S. domestic air carriers under similar circumstances (unless such data are specifically requested by a Taxing Authority). For purposes of this Section 9.3, a

“Final Determination” is (1) a decision, judgment, decree, or other order by any court of competent jurisdiction that occurs pursuant to the provisions of Section 9.3(e), which decision, judgment, decree, or other order has become final and unappealable, (2) a closing agreement or settlement agreement entered into in accordance with Section 9.3(e) that has become binding and is not subject to further review or appeal (absent fraud, misrepresentation, etc.), or (3) the termination of administrative proceedings and the expiration of the time for instituting a claim in a court proceeding; provided that, notwithstanding the foregoing, the positions taken by such Tax Indemnitee on its Tax returns and filings, dealing with Tax authorities and, subject to the provisions of Section 9.3(e) hereof, in any Tax proceedings shall be in the sole, good-faith discretion of such Tax Indemnitee and, subject to the provisions of Section 9.3(d)(2) hereof, no Person shall have the right to require disclosure of the Tax returns or filings of such Tax Indemnitee, provided further that, in the case of any Tax credit or other Tax benefit that is limited in its availability, in the aggregate, to such Tax Indemnitee (and is not directly and fully traceable to the Tax paid or indemnified by Borrower without such limitations), the allocation of such Tax credit or other Tax benefit shall be made in a manner consistent with the requirements of applicable Law, and if and to the extent such allocation is not addressed by applicable Law, in proportion to other Tax credits or Tax benefits claimed by such Tax Indemnitee (taking into account any requirement of applicable Law concerning segregation or basketing of similar Tax credits or Tax benefits), by multiplying the amount of such Tax credit or Tax benefit by the ratio of the Tax credit or Tax benefit realized by the Tax Indemnitee by reason of any Tax paid or indemnified by Borrower over the total of such available Tax credits or Tax benefits for the Tax year at issue (taking into account any requirement of applicable Law concerning segregation or basketing of similar Tax credits or Tax benefits).

(5) If any Tax Indemnitee actually realizes a net tax savings by reason of any Tax paid or indemnified by Borrower pursuant to this Section 9.3 (whether such tax savings arise by means of a foreign tax credit, depreciation or cost recovery deduction, or otherwise), and such net savings is not otherwise taken into account in computing such payment or indemnity, such Tax Indemnitee shall pay to Borrower an amount equal to the lesser of (1) the amount of such net tax savings, plus any additional net tax savings recognized as the result of any payment made pursuant to this sentence, and (2) the amount of all payments pursuant to this Section 9.3 by Borrower to such Tax Indemnitee (less any payments previously made by such Tax Indemnitee to Borrower pursuant to this Section 9.3(d)(5)) (and the excess, if any, of the amount described in clause (1) over the amount described in clause (2) shall be carried forward and applied to reduce pro tanto any subsequent obligations of Borrower to make payments to such Tax Indemnitee pursuant to this Section 9.3); provided, that such Tax Indemnitee shall not be required to make any payment pursuant to this sentence so long as a Special Default or an Event of Default exists. If a tax benefit is later disallowed or denied, the disallowance or denial shall be treated as a Tax indemnifiable under Section 9.3(b) without regard to the provisions of Section

9.3(c) (other than Section 9.3(c)(5), (8) or (10)). Each such Tax Indemnitee shall in good faith use reasonable efforts in filing its tax returns and in dealing with Taxing Authorities to seek and claim any such tax benefit.

(e) Contest.

(1) If a written claim is made against a Tax Indemnitee for Taxes with respect to which Borrower could be liable for payment or indemnity hereunder, or if a Tax Indemnitee determines that a Tax is due for which Borrower could have an indemnity obligation hereunder, such Tax Indemnitee shall promptly notify Borrower in writing of such claim (provided, that failure so to notify Borrower shall not relieve Borrower of its indemnity obligations hereunder except to the extent that such failure has a material adverse effect on Borrower’s indemnification obligations hereunder or on Borrower’s rights to successfully contest such claim), and shall take no action with respect to such claim without Borrower’s prior written consent for 30 days following Borrower’s receipt of such notice; provided, that, if applicable Law requires such Tax Indemnitee to take action before the end of such 30-day period, such Tax Indemnitee shall, in such notice to Borrower, so inform Borrower, and such Tax Indemnitee shall take no action for as long as it is legally able to avoid taking action. Such Tax Indemnitee shall (provided that Borrower shall have agreed to keep such information confidential other than to the extent necessary in order to contest the claim, such agreement to be delivered to the Tax Indemnitee and in form and substance reasonably acceptable to it) furnish Borrower with copies of the relevant portions of any requests for information from any Taxing Authority relating to such Taxes with respect to which Borrower may be required to indemnify hereunder. If requested by Borrower in writing within 30 days after its receipt of such notice, such Tax Indemnitee shall, at Borrower’s expense (including all reasonable out-of-pocket costs and expenses, including reasonable attorneys’ and accountants’ fees and disbursements incurred in connection with, and reasonably allocable to, the contest of such Tax), in good faith contest (or, if permitted by applicable Law, allow Borrower to contest) through appropriate administrative and judicial proceedings the validity, applicability, or amount of such Taxes by (x) resisting payment thereof, (y) not paying the Taxes except under protest if protest is necessary and proper, or (z) if the payment is made, using reasonable efforts to obtain a refund thereof in an appropriate administrative or judicial proceeding. If requested to do so by Borrower in writing, the Tax Indemnitee shall appeal any adverse administrative or judicial decision, except that the Tax Indemnitee shall not be required to pursue any appeals to the United States Supreme Court. If and to the extent that the Tax Indemnitee is able, using reasonable efforts, to separate the contested issue or issues from other issues arising in the same administrative or judicial proceeding that are unrelated to the Transactions without (in such Tax Indemnitee’s good faith judgment) adversely affecting such Tax Indemnitee, such Tax Indemnitee shall permit Borrower to control the conduct of any such proceeding and shall provide to Borrower (at Borrower’s cost and expense) such information or data in such Tax Indemnitee’s control or possession and reasonably necessary to conduct such contest. If the

contest is being controlled by a Tax Indemnitee, such Tax Indemnitee shall consult with Borrower in good faith regarding the manner of contesting such claim, and shall keep Borrower reasonably informed regarding the progress of such contest. If the contest is being controlled by Borrower, Borrower shall consult with the applicable Tax Indemnitee in good faith regarding the manner of contesting such claim, and shall keep such Tax Indemnitee reasonably informed regarding the progress of such contest. A Tax Indemnitee shall not fail to take any action expressly required by this Section 9.3(e) (including any action regarding any appeal of an adverse determination with respect to any claim) or settle or compromise any claim without Borrower’s prior written consent (except as contemplated by Sections 9.3(e)(2) or (3)).

(2) Notwithstanding the foregoing, in no event shall a Tax Indemnitee be required to pursue any contest (or to permit Borrower to pursue any contest) unless (1) Borrower agrees to pay such Tax Indemnitee on demand all reasonable out-of-pocket costs and expenses that such Tax Indemnitee incurs in connection with contesting such Taxes, including all reasonable out-of-pocket costs and expenses and reasonable attorneys’ and accountants’ fees and disbursements, in each case, to the extent reasonably allocable to the contest of such Taxes), (2) if such contest involves the payment of the claim, Borrower advances the amount thereof (to the extent indemnified hereunder) that are required to be paid before commencing the contest on an interest-free after-tax basis to such Tax Indemnitee (and such Tax Indemnitee shall promptly pay to Borrower any net realized tax benefits resulting from such advance, including any tax benefits resulting from making such payment), (3) the action to be taken will not result in any material risk of forfeiture, sale, or loss of, or the creation of a Lien (other than a Permitted Lien) on, the Aircraft or the Collateral (unless Borrower makes provisions to protect the interests of any such Tax Indemnitee in a manner reasonably satisfactory to such Tax Indemnitee) or any material risk of criminal liability or material civil liability (provided, that such Tax Indemnitee shall notify Borrower in writing promptly after it becomes aware of any such risks), (4) no Event of Default exists (unless Borrower has provided security reasonably acceptable to the Tax Indemnitee for its obligations hereunder or has advanced to such Tax Indemnitee, before proceeding or continuing with such contest, the amount of the Tax being contested, plus any interest and penalties and an amount estimated in good faith by such Tax Indemnitee for expenses) and (5) before commencing any judicial action controlled by Borrower, such Tax Indemnitee shall have received written confirmation from Borrower that the Taxes that are the subject of such Tax claim are indemnified by Borrower hereunder, provided, that Borrower shall not be bound by such confirmation to the extent that the Final Determination of the contest articulates conclusions of law and fact that demonstrate Borrower is not liable hereunder for the Taxes that are the subject of such Tax claim. . Notwithstanding the foregoing, if any Tax Indemnitee releases, waives, compromises, or settles any claim that may be indemnifiable by Borrower pursuant to this Section 9.3 without Borrower’s written permission, Borrower’s obligation to indemnify such Tax Indemnitee with respect to such claim (and all directly-related claims, and claims based on the

outcome of such claim) shall terminate, and such Tax Indemnitee shall repay to Borrower any amount previously paid or advanced to such Tax Indemnitee with respect to such claim (other than previously incurred costs and expenses of contest described in clause (1) of this paragraph), plus interest at the rate that would have been payable by the relevant Taxing Authority on a refund of such Tax.

(3) Notwithstanding anything contained in this Section 9.3, a Tax Indemnitee will not be required to contest the imposition of any Tax, and shall be permitted to settle or compromise any claim without Borrower’s consent, if such Tax Indemnitee (1) waives its right to indemnity under this Section 9.3 with respect to such Tax (and any directly-related claim, and any claim the outcome of which is determined based upon the outcome of such claim), (2) pays to Borrower any amount previously paid or advanced by Borrower pursuant to this Section 9.3 with respect to such Tax (other than previously incurred costs and expenses of contest described in clause (1) of this paragraph), plus interest at the rate that would have been payable by the relevant Taxing Authority on a refund of such Tax, and (3) agrees to discuss with Borrower the views or positions of any relevant Taxing Authority with respect to the imposition of such Tax.

(f) Refund. If any Tax Indemnitee receives a refund of, or is entitled to a credit against other liability for, all or any part of any Taxes paid, reimbursed, or advanced by Borrower, such Tax Indemnitee shall pay to Borrower within 30 days of such receipt an amount equal to the lesser of (a) the amount of such refund or credit plus any net tax benefit (taking into account any Taxes incurred by such Tax Indemnitee by reason of the receipt of such refund or realization of such credit) actually realized by such Tax Indemnitee as a result of any payment by such Tax Indemnitee made pursuant to this sentence (including this clause (a)), and (b) such tax payment, reimbursement, or advance by Borrower to such Tax Indemnitee theretofore made pursuant to this Section 9.3 (and the excess, if any, of the amount described in clause (a) over the amount described in clause (b) shall be carried forward and applied to reduce pro tanto any subsequent obligation of Borrower to make payments to such Tax Indemnitee pursuant to this Section 9.3). If, in addition to such refund or credit, such Tax Indemnitee receives (or is credited with) an amount representing interest on the amount of such refund or credit, such Tax Indemnitee shall pay to Borrower within 30 days after receiving or realizing such credit that proportion of such interest fairly attributable to Taxes paid, reimbursed, or advanced by Borrower before the receipt of such refund or realization of such credit. Anything herein to the contrary notwithstanding, a Tax Indemnitee shall not be required to make any payment pursuant to this subsection 9.3(e) so long as a Special Default or an Event of Default exists.

(g) Tax Filing. Borrower shall, at its expense, timely file any report, return, or statement that is required to be filed with respect to any Tax which is subject to indemnification under this Section 9.3 (except for any such report, return, or statement which a Tax Indemnitee has timely notified Borrower in writing that such Tax Indemnitee intends to file, or for which such Tax Indemnitee is required by law to file, in its own name); provided, that the relevant Tax Indemnitee shall furnish Borrower with

any information in such Tax Indemnitee’s possession or control that is reasonably necessary to file any such return, report, or statement and that Borrower reasonably requests in writing. Borrower shall either file such report, return, or statement and send a copy to such Tax Indemnitee, or, if Borrower is not permitted to file such report, return, or statement, it shall notify such Tax Indemnitee of such requirement and prepare and deliver such report, return, or statement to such Tax Indemnitee in a manner reasonably satisfactory to such Tax Indemnitee within a reasonable time before the time such report, return, or statement is to be filed; provided, that the relevant Tax Indemnitee shall either furnish Borrower with any information in such Tax Indemnitee’s possession or control that is reasonably necessary to file any such return, report, or statement and that Borrower reasonably requests in writing or such Tax Indemnitee shall itself be responsible for completing and filing such report, return or statement if it fails to, or elects not to, provide Borrower with the requested information.

(h) Forms. Each Tax Indemnitee agrees to furnish from time to time to Borrower, the relevant Mortgagee, or such other Person as Borrower or such Mortgagee shall designate, at Borrower’s or Mortgagee’s request, such duly-executed and properly-completed forms as may be necessary or appropriate in order to claim any reduction of or exemption from any withholding or other Tax imposed by any Taxing Authority, if (i) such reduction or exemption is available to such Tax Indemnitee without such Tax Indemnitee’s incurring material adverse consequences under applicable Law, and (ii) Borrower has provided such Tax Indemnitee with any information necessary to complete such form not otherwise reasonably available to such Tax Indemnitee. If the Tax Indemnitee believes that claiming such reduction or exemption would result in its incurring material adverse consequences under applicable Law, the Tax Indemnitee shall notify Borrower of the basis of that belief, and the Tax Indemnitee and Borrower shall promptly meet to discuss the matter and, if the Tax Indemnitee and Borrower are unable to agree whether such material adverse consequences would result, shall appoint an independent accounting firm to resolve the issue on terms similar to those set forth in Section 9.3(d)(2) hereof (except that the Tax Indemnitee and Borrower shall share equally the costs of such accounting firm).

(i) Non-Parties. If a Tax Indemnitee is not a party to this Agreement, Borrower may require the Tax Indemnitee to agree in writing, in a form reasonably acceptable to Borrower, to the terms of this Section 9.3 and Section 11.8 before any payment shall be due to such Tax Indemnitee under this Section 9.3.

9.4

Payments.

Except as otherwise provided herein, any payments which Borrower or an Indemnitee or Tax Indemnitee is obligated to make pursuant to Section 9.1 or Section 9.3 shall be paid on the 30th day after demand, but not before five (5) days before the date such Expense or Tax is due or payable by such Indemnitee or Tax Indemnitee, as applicable. If Borrower shall have requested to contest a Tax or Expense as provided in this Section 9 and shall have duly complied with all the terms of this Section 9, Borrower’s liability for indemnification under this Section 9 shall, at Borrower’s election, be deferred until a final determination is made with respect to such contest. At such time, Borrower shall become obligated for the payment of any indemnification

hereunder resulting from the outcome of such contest, and within fifteen (15) days following such final determination, any amounts so due hereunder shall be paid by Borrower to the Indemnitee or Tax Indemnitee, as applicable. Such payments shall be made directly to the relevant Indemnitee or Tax Indemnitee or to Borrower, in immediately available funds at such bank or to such account as specified by such Indemnitee or Tax Indemnitee or Borrower (as applicable) in written directives to the payor, or, if no such direction has been given, by check of the payor payable to the order of, and mailed to, such Indemnitee or Tax Indemnitee or Borrower (as applicable) by certified mail, postage prepaid, at its address as set forth in this Agreement.

9.5

Interest.

If any amount, payable by Borrower, any Indemnitee, or any Tax Indemnitee under Section 9.1 or Section 9.3 is not paid when due, the Person obligated to make such payment shall pay on demand, to the extent permitted by Law, to the Person entitled thereto, interest on any such amount for the period from and including the due date for such amount to but excluding the date the amount is paid, at the Past-Due Rate. Such interest shall be paid in the same manner as the unpaid amount in respect of which such interest is due.

9.6

Benefit of Indemnities.

Borrower’s obligations for indemnities, obligations, adjustments, and payments in Section 9.1 or Section 9.3 are expressly made for the benefit of, and shall be enforceable by, the Indemnitee or Tax Indemnitee entitled thereto as and to the extent provided herein, notwithstanding any provision of the Mortgage.

Any and all property described or referred to in the granting clauses hereof which Borrower acquires in the future and required or deemed to be subjected to the Lien herein pursuant to the provisions hereof shall ipso facto, and without any other conveyance, assignment, or act on the part of Borrower or Mortgagee, become and be subject to the Lien herein granted as fully and completely as though specifically described herein, but nothing in this paragraph shall modify or change Borrower’s obligations in the foregoing paragraphs.

Borrower and Mortgagee further agree as follows:

1. DEFINITIONS

The terms defined in Annex A, when capitalized as in Annex A, have the same meanings when used in this Mortgage. Annex A also contains rules of usage that control construction in this Mortgage.

2. THE EQUIPMENT NOTES

2.1

Form of Equipment Notes.

The Equipment Notes shall be substantially in the form of Exhibit B.

2.2

Issuance and Terms of Equipment Notes.

The Equipment Notes shall be dated the date of the Closing Date and shall have the maturity and principal amounts and shall bear interest set forth therein. On the Closing Date, Borrower shall issue the Equipment Notes to the Lenders. The Equipment Notes shall be registered in the Equipment Note Register (as defined in Section 2.6) at the time of issuance.

The Equipment Notes shall be executed on behalf of Borrower by one of its authorized officers. Equipment Notes bearing the signatures of individuals who were the proper officers of Borrower at the time of such execution shall bind Borrower, notwithstanding that such individuals or any of them have ceased to hold such offices before the authentication and delivery of such Equipment Notes. Borrower may from time to time execute and deliver Equipment Notes with respect to the Aircraft to Mortgagee for authentication upon original issue, and Mortgagee thereupon shall authenticate and deliver such Equipment Notes upon Borrower’s written request signed by an authorized officer of Borrower. No Equipment Note shall be secured by or entitled to any benefit under this Mortgage, 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 Mortgagee by the manual signature of one of its authorized officers, and such certificate upon any Equipment Note shall be conclusive evidence, and the only evidence, that such Equipment Note has been duly authenticated and delivered hereunder.

The aggregate Original Amount of the Equipment Notes issued hereunder shall not exceed the amount set forth as the maximum therefor on Schedule 2 of the Loan Agreement.

2.3

Method of Payment.

(a) The Original Amount of, interest on, and other amount due under each Equipment Note or hereunder will be payable in Dollars by wire transfer of immediately available funds not later than 11:00 a.m., New York time, on the due date of payment to Mortgagee at the Corporate Trust Office for distribution in the manner provided herein

(any payment received after such time being deemed received on the next following Business Day). Notwithstanding the foregoing or any provision in any Equipment Note to the contrary, Mortgagee will pay or cause to be paid all amounts to be paid by Borrower hereunder and under any Equipment Note to the holder thereof (including all amounts distributed pursuant to Article 3 of this Mortgage) by transferring, or causing to be transferred, by wire transfer of immediately available funds in Dollars, before 2:00 p.m., New York City time, on the due date for 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 Mortgagee fails to initiate the transfer by federal wire transfer of any such payment as provided in the foregoing sentence after its receipt of funds at the place and before the time specified above by reason of its failure to use ordinary care, WFB shall compensate such holders for loss of use of funds at the Debt Rate until such payment is made, and 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 Mortgagee for cancellation promptly after such payment. Notwithstanding any other provision of this Mortgage to the contrary, Mortgagee shall not be required to make, or cause to be made, wire transfers as aforesaid before the first Business Day on which it is practicable for 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 11:00 a.m., New York time, at the place of payment. Before the due presentment for registration of transfer of any Equipment Note, Borrower and 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 neither Borrower nor Mortgagee shall be affected by any notice to the contrary. So long as any signatory to the Loan Agreement or nominee thereof shall be a registered Lender, all payments to it shall be made to the account of such Lender specified in Schedule 1 of the Loan Agreement, and otherwise in the manner provided in or pursuant to the Loan Agreement, unless and until it specifies some other account or manner of payment by notice to Mortgagee consistent with this Section 2.3.

(b) Mortgagee (as agent for Borrower) agrees (1) to act as withholding agent in connection with the Mortgage and the Loan Agreement, (2) whenever any present or future United States taxes or similar charges are required by applicable Law to be withheld from a payment of Original Amount of, interest on, or other amounts due hereunder or under an Equipment Note or under the Loan Agreement, to withhold such amounts as are required by applicable Law and timely pay the same to the appropriate authority in the name of and on behalf of the applicable Lenders (and such amount withheld shall constitute payment by Borrower of such amount under the applicable Equipment Note or hereunder or under the Loan Agreement, as the case may be (but, for the avoidance of doubt, such Lender shall still be entitled to gross-ups and indemnities pursuant to the terms of the Operative Agreements with respect to such payment if the Operative Agreements so provide), (3) to file any necessary United States withholding tax returns or statements when due (including an IRS Form 1042-S), and (4) as promptly

as possible after the payment thereof, to deliver to each Lender (with a copy to Borrower) appropriate receipts, if available, showing the payment thereof, together with such additional documentary evidence as any such Lender reasonably requests from time to time.

(c) In the case of a Lender that is a Non-U.S. Person, such Lender shall furnish such Mortgagee with a properly completed and executed withholding certificate on an IRS Form W-8BEN or W-8ECI (or any successor forms), as applicable, or such other applicable documentation as may be necessary to enable such Lender to claim an exemption from, or reduced rate of, such taxes. Provided that such Lender has furnished Mortgagee with the requested forms and other documentation duly executed by such Lender and has not notified the Mortgagee of the withdrawal or inaccuracy of such form prior to the date of an interest payment, only the reduced amount (if any) required by applicable Law shall be withheld from payments under the Equipment Notes held by such Lender in respect of United States federal income tax. In the case of a Lender that is a U.S. Person and (1) not an Exempt Recipient that has furnished to the Mortgagee a properly completed and currently effective U.S. Treasury Form W-9 or (2) that is an Exempt Recipient (not required to deliver an IRS form W-9), no amount shall be withheld from payments under the Equipment Notes held by such Lender in respect of United States federal income tax. If a Lender has notified Mortgagee that any of the foregoing forms or certificates that it delivered is withdrawn or inaccurate, or if the Internal Revenue Code or the regulations thereunder or the administrative interpretation thereof are 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 Lender, or if such withholding is otherwise required, Mortgagee agrees to withhold from each payment due to the relevant Lender withholding taxes at the appropriate rate under applicable law, and will, as more fully provided above, on a timely basis, deposit such amounts with an authorized depository and make such returns, filings, and other reports in connection therewith, and in the manner required under applicable Law. For purposes of this paragraph, an “Exempt Recipient” is a Person described in Code §6049(b)(4).

(d) Neither Borrower nor Mortgagee shall have any liability to a Lender as a result of any false, inaccurate, or untrue statement in any form provided by such Lender hereunder.

2.4

Application of Payments.

Each payment of Original Amount, LIBOR Breakage Amount, Redemption Fee and interest due thereon shall be applied:

FIRST: to pay any amount due hereunder or under such Equipment Note other than any amount designated under this Section 2.4 to be paid pursuant to clauses “SECOND”, “THIRD” or “FOURTH”;

SECOND: to pay accrued interest on such Equipment Note (and any interest on any overdue amount) to the date of such payment;

THIRD: to pay the Original Amount of such Equipment Note (or a portion thereof) then due thereunder; and

FOURTH: to pay 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 2.9, 2.10, and 2.11).

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.

2.5

Termination of Interest in Collateral.

No Lender shall have any further interest in, or other right with respect to, the Collateral when and if the Original Amount of, and interest on and other amounts due under all Equipment Notes held by such Lender and all other sums then due and payable to such Lender (to the extent secured hereby), or Mortgagee hereunder and under the other Operative Agreements by Borrower (collectively, the “Secured Obligations”) have been paid in full.

2.6

Registration, Transfer, and Exchange of Equipment Notes.

Mortgagee shall keep a register (the “Equipment Note Register”) in which 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 registered hereunder. Mortgagee shall keep the Equipment Note Register at its Corporate Trust Office. 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 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(s) and address(es) of the new holder(s). Upon surrender for registration of transfer of any Equipment Note, Borrower shall execute, and Mortgagee shall authenticate and deliver, in the name(s) of the designated transferee(s), one or more new Equipment Notes of a like aggregate Original Amount. At the Lender’s option, 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 Mortgagee at the Corporate Trust Office. Whenever any Equipment Notes are so surrendered for exchange, Borrower shall execute, and Mortgagee shall authenticate and deliver, the Equipment Notes which the Lender 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 2.6 or under Section 2.7 or otherwise under this Mortgage) shall be the valid obligations of Borrower evidencing the same respective obligations, and entitled to the same security and benefits under this Mortgage, 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 Mortgagee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to Mortgagee duly executed by the Lender or such holder’s attorney duly authorized in writing. 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. Borrower shall not be required to exchange any surrendered Equipment Notes as provided above during the 10-day period preceding the due date of any payment on such Equipment Note. Borrower 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 Borrower with respect to such Equipment Note, and for all other purposes, until Borrower receives from Mortgagee a notice stating otherwise and such change is reflected on the Equipment Note Register. Mortgagee will promptly notify Borrower of each registration of a transfer of an Equipment Note. Any such transferee of an Equipment Note, by its acceptance of an Equipment Note, agrees to the provisions of this Mortgage and the Loan Agreement applicable to Lenders, including Sections 6 and 7.1 of the Loan Agreement, and shall be deemed to have covenanted to the parties to the Loan Agreement as to the matters covenanted by the original Lender in the Loan Agreement. Subject to compliance by the Lender and its transferee (if any) of the requirements in this Section 2.6, Mortgagee and Borrower 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.

2.7

Mutilated, Destroyed, Lost, or Stolen Equipment Notes.

If any Equipment Note shall become mutilated, destroyed, lost, or stolen, upon the written request of the holder of such Equipment Note, Borrower shall execute, and 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 Mortgagee and a photocopy thereof shall be furnished to Borrower. If the Equipment Note being replaced has been destroyed, lost, or stolen, the holder of such Equipment Note shall furnish to Borrower and Mortgagee (a) such security or indemnity as they require to save Borrower and Mortgagee harmless, and (b) evidence satisfactory to Borrower and 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 Borrower 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 the Lender’s compliance with the requirements in this Section 2.7, Mortgagee and Borrower shall use all reasonable efforts to issue new Equipment Notes within 10 Business Days after receiving the Lender’s written request therefor.

2.8

Payment of Expenses on Transfer; Cancellation.

(a) No service charge shall be made to a Lender for any registration of transfer or exchange of Equipment Notes, but Mortgagee, as Equipment Note Registrar,

may require payment from any such Lender 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) Mortgagee shall cancel all Equipment Notes surrendered for replacement, redemption, transfer, exchange, payment, or cancellation, and shall destroy the cancelled Equipment Notes.

2.9

Mandatory Redemptions of Equipment Notes.

On the date on which Borrower is required pursuant to Section 4.5 to prepay the Equipment Notes following an Event of Loss to the Airframe, all 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 plus any LIBOR Breakage Amount and all other Secured Obligations owed or then due and payable to the Lenders in respect thereto.

2.10

Voluntary Redemptions of Equipment Notes.

Borrower may redeem all or any part of the unpaid Original Amount of the Equipment Notes upon at least 5 Business Days’ prior written notice to Mortgagee and the Lenders. The Equipment Notes shall be redeemed in whole or in part without penalty or premium (except as provided below) together with accrued interest on the amount to be redeemed provided, except in the case of a redemption of Equipment Notes with respect to which (1) Indemnified Withholding Taxes are then payable by Borrower pursuant to Section 9.3 of the Loan Agreement or (2) Increased Costs are then payable by Borrower pursuant to Section 4.4 of the Loan Agreement (each an “Optional Redemption Triggering Event”), Borrower may not redeem an aggregate unpaid Original Amount of less than One Million Dollars ($1,000,000) or, if less, the then outstanding Original Amount; and provided, further, that notwithstanding anything to the contrary in this Mortgage, the proceeds of any partial redemption shall be distributed by Mortgagee to the Lenders ratably, except in the case of a redemption of Equipment Notes with respect to which an Optional Redemption Triggering Event shall have occurred, in which case the proceeds of such redemption shall be distributed to the Lender or Lenders of the Equipment Notes to which such Optional Redemption Triggering Event relate. Borrower shall not be entitled to reborrow any amounts redeemed. In connection with any redemption (except in the case of a redemption of Equipment Notes with respect to which an Optional Redemption Triggering Event has occurred) of all or part of any Equipment Note having a redemption date prior to the third (3rd) anniversary of the Closing Date, Borrower shall pay to the holder of any such Equipment Note a redemption fee (the “Redemption Fee”) equal to a percentage (set forth in the table below opposite the period in which any such redemption date occurs) of the redeemed unpaid Original Amount of any such Equipment Note.

3.2

Event of Loss; Replacement; Optional Redemption.

Except as otherwise provided in Section 3.3, any payments received by Mortgagee (1) with respect to the Airframe or the Airframe and one or more Engines as the result of an Event of Loss or (2) pursuant to an optional redemption of all of the unpaid Original Amount of the Equipment Notes pursuant to Section 2.10 shall be applied to redeem the Equipment Notes and to all other Secured Obligations by applying such funds in the following order of priority:

FIRST, (a) to reimburse Mortgagee and the Lenders for any reasonable costs or expenses incurred in connection with such redemption for which they are entitled to reimbursement, or indemnity by Borrower, under the Operative Agreements, and then (b) to pay any other Secured Obligations then due (except as provided in clause “SECOND” below) to Mortgagee and the Lenders under this Mortgage, the Loan Agreement, or the Equipment Notes (other than amounts specified in clause SECOND of this Section 3.2);

3.3

Payments after Event of Default.

Except as otherwise provided in Section 3.4, all payments received and amounts held or realized by Mortgagee (including any amounts realized by Mortgagee from the exercise of any remedies pursuant to Article 5) if an Event of Default exists and after the acceleration specified in Section 5.2(b), as well as all payments or amounts then held by Mortgagee as part of the Collateral, shall be promptly distributed by Mortgagee in the following order of priority:

FIRST, so much of such payments or amounts as shall be required to reimburse Mortgagee or WFB for any tax (except to the extent resulting from a failure of Mortgagee to withhold taxes pursuant to Section 2.3(b)), expense, or other loss (including all amounts to be expended at the expense of, or charged upon the rents, revenues, issues, products, and profits of, the property included in the Collateral (all such property being herein the “Mortgaged Property”) pursuant to Section 5.3(b)) incurred by Mortgagee or WFB (to the extent not previously reimbursed), the expenses of any sale, or other proceeding, reasonable attorneys’ fees and expenses, court costs, and any other expenditures incurred or expenditures or advances made by Mortgagee, WFB, Agent or the Lenders in the protection, exercise, or enforcement of any right, power, or remedy or any damages sustained by Mortgagee, WFB, Agent or any Lender, liquidated or otherwise, upon such Event of Default shall be applied by Mortgagee as between itself, WFB, Agent and the Lenders to reimburse such expenses and any other expenses for which Mortgagee, WFB, Agent or the Lenders are entitled to reimbursement under any Operative Agreement; and if the aggregate amount to be so distributed is insufficient to pay all amounts described above, then ratably, without priority of one over the other, in proportion to the amounts owed each hereunder;

SECOND, so much of such payments or amounts remaining as shall be required to pay in full the unpaid Original Amount of the Equipment Notes, and the accrued but unpaid interest and other amounts due thereon and any LIBOR Breakage Amount and all other Secured Obligations to the date of distribution, shall be distributed to the Lenders, and if the amount so to be distributed is insufficient to pay in full, then ratably, without priority of one over the other, in the proportion that (x) the unpaid Original Amount of the Equipment Notes held by each holder plus the accrued but unpaid interest and other amounts due hereunder or thereunder to the distribution date, bears to (y) the aggregate unpaid Original Amount of the Equipment Notes held by all such holders plus the accrued but unpaid interest and other amounts due thereon to the distribution date;

THIRD, subject to Section 7.5 of the Loan Agreement, so much of such payments or amounts remaining as is required to pay in full the amounts specified in clauses FIRST and SECOND of Section 3.3 of each Related Mortgage, pro rata as to amounts outstanding, but with priority of such clause FIRST amounts over such clause SECOND amounts; and

Liens; Amendments to Mortgagor Agreements.

Borrower will not directly or indirectly create, incur, assume, or suffer to exist any Lien or with respect to the Airframe or any Engine or any other Collateral, title to any of the foregoing, or any interest of Borrower therein, except Permitted Liens. Borrower shall promptly, at its own expense, take such action as may be necessary duly to discharge (by bonding or otherwise) any Lien other than a Permitted Lien arising at any time. Except as otherwise permitted in this Mortgage, Borrower will not enter into any agreement amending or supplementing any Mortgagor Agreement (other than a Permitted Lease) which would adversely affect the rights and interest of the Mortgagee without the consent of the Mortgagee.

4.2

Possession; Operation and Use; Maintenance; Registration; Markings.

(a) General. Except as otherwise expressly provided herein, Borrower shall be entitled to operate, use, locate, employ, or otherwise utilize or not utilize the Airframe, any Engine or any Parts in any lawful manner or place in accordance with Borrower’s business judgment.

(b) Possession. Borrower shall not, without Mortgagee’s prior written consent, lease or otherwise in any manner deliver, transfer, or relinquish possession of the Aircraft, the Airframe, or any Engine, or install any Engine, or permit any Engine to be installed, on any airframe other than the Airframe; except that Borrower may, without such prior written consent:

(1) subject or permit any Permitted Lessee to subject (aa) the Airframe to normal interchange agreements or (bb) any Engine to normal interchange agreements or pooling agreements or arrangements, in each case customary in the commercial airline industry and entered into by Borrower or such Permitted

Lessee in the ordinary course of business; provided, that if Borrower’s title to any such Airframe or Engine is divested under any such agreement or arrangement, then such Airframe or Engine shall be deemed to have suffered an Event of Loss as of the date of such divestiture, and Borrower shall comply with Section 4.4(e) in respect thereof;

(2) deliver or permit any Permitted Lessee to deliver possession of the Aircraft, the Airframe, any Engine, or any Part (aa) to the manufacturer thereof or to any third-party maintenance provider for testing, service, repair, maintenance, or overhaul work on the Aircraft, the Airframe, any Engine, or any Part, or, to the extent required or permitted by Section 4.4, for alterations or modifications in or additions to the Aircraft, the Airframe, or any Engine, or (bb) to any Person for the purpose of transport to a Person referred to in the preceding clause (aa);

(3) install or permit any Permitted Lessee to install an Engine on an airframe owned by Borrower or such Permitted Lessee free and clear of all Liens, except (aa) Permitted Liens and those that do not apply to the Engines, and (bb) the rights of third parties under normal interchange or pooling agreements and arrangements of the type permitted under Section 4.2(b)(1);

(4) install or permit any Permitted Lessee to install an Engine on an airframe leased to Borrower or such Permitted Lessee, or purchased or owned by Borrower or such Permitted Lessee subject to a security agreement, conditional sale, or other secured financing arrangement, but only if (aa) such airframe is free and clear of all Liens, except (i) the rights of the parties to such lease, or any such secured financing arrangement, covering such airframe, and (ii) Liens of the type permitted by clause (3) of this Section 4.2(b), and (bb) Borrower or Permitted Lessee has received from the lessor, secured party, or conditional seller in respect of such airframe, a written agreement (which may be a copy of the lease, security agreement, conditional sale agreement, or other agreement covering such airframe), whereby such Person agrees that it will not acquire or claim any right, title, or interest in, or Lien on, such Engine by reason of the installation of such Engine on such airframe at any time while such Engine is subject to the Lien of this Mortgage;

(5) install or permit any Permitted Lessee to install an Engine on an airframe owned by or leased to Borrower or such Permitted Lessee subject to a conditional sale or other security agreement under circumstances where neither clause (3) nor clause (4) of this Section 4.2(b) applies; provided, that any such installation shall be deemed an Event of Loss with respect to such Engine, and Borrower shall comply with Section 4.4(e) in respect thereof;

(6) transfer or permit any Permitted Lessee to transfer possession of the Aircraft, the Airframe, or any Engine to (aa) a U.S. Government Entity pursuant to CRAF or (bb) to any other Government Entity in the country of registry whose obligations are supported by the full faith and credit of such country when required by applicable Law. Neither such event shall, for the avoidance of doubt, be deemed to be an Event of Loss;

(7) enter into a Wet Lease with respect to the Aircraft or any other aircraft on which any Engine may be installed (which shall not be considered a transfer of possession hereunder); provided, that Borrower’s obligations hereunder shall continue in full force and effect notwithstanding any Wet Lease;

(8) if no Special Default or Event of Default exists, and subject to the following paragraph, enter into a lease with respect to the Aircraft, the Airframe, or any Engine to with any of the following Persons (so long as such Person is not then subject to any bankruptcy, insolvency, liquidation, reorganization, dissolution, or similar proceeding and shall not have substantially all of its property in the possession of any liquidator, trustee, receiver, or similar Person): (aa) any Permitted Air Carrier or Permitted Manufacturer; but only if, in the case only of a lease to a Permitted Foreign Air Carrier or a Non-U.S. domiciled Permitted Manufacturer (and pursuant to such lease, the Aircraft is to be registered outside the United States), Borrower furnishes Mortgagee a favorable opinion, in form and substance satisfactory to Mortgagee, of counsel selected by Borrower and satisfactory to Mortgagee located in the country of domicile of such Permitted Foreign Air Carrier or Permitted Manufacturer, (x) that there are no possessory rights in favor of Borrower, any Permitted Lessee, or any third party (including any Government Entity) which would, upon bankruptcy or other default by Borrower (assuming that the Permitted Lessee is not itself the subject of any bankruptcy proceedings), prevent or unreasonably delay the return of the Aircraft to Borrower in accordance with and when permitted by the terms of this Mortgage upon Mortgagee’s exercise of its remedies hereunder and the rights of Mortgagee hereunder shall not in any other way be materially adversely affected and (y) to such further effect as the Lenders may require; (bb) any Affiliate of Borrower that is a U.S. Air Carrier; or (cc) a U.S. Government Entity or a Government Entity of the country of registration of the Aircraft, in each case bearing the full faith and credit of the government;

provided, that (1) the rights of any transferee who receives possession by reason of a transfer permitted by this Section 4.2(b) (other than by a transfer of an Engine which is deemed an Event of Loss) shall be subject and subordinate to this Mortgage and to Mortgagee’s rights, powers and remedies hereunder, including (x) Mortgagee’s right to repossess the Aircraft pursuant to Section 5.2, (y) Mortgagee’s right to terminate and avoid such lease, delivery, transfer or relinquishment of possession if an Event of Default exists, and (z) the right to require such Person to deliver the Aircraft, the Airframe, and Engines subject to such transfer forthwith if an Event of Default exists, (2) Borrower shall remain primarily liable for the performance of this Mortgage and all the terms and conditions of this Mortgage and the other Operative Agreements shall remain in effect, (3) no lease or transfer of possession otherwise in compliance with this Section 4.2(b) shall (aa) result in any registration or re-registration of an Aircraft (except to the extent permitted by Section 4.2(e)) or the maintenance, operation, or use thereof except in compliance with Sections 4.2(c) and 4.2(d), or (bb) permit any action not permitted to Borrower hereunder and (4) Borrower shall notify Lenders promptly after entering into any lease permitted by this Section 4.2(b).

In the case of any lease permitted under this Section 4.2(b), Borrower will include in such lease appropriate provisions which (x) make such lease expressly subject and subordinate to this Mortgage, including Mortgagee’s right to avoid such lease in the exercise of its rights to repossession of the Airframe and Engines hereunder; (y) require the Permitted Lessee to comply with Section 4.6, to the extent that Borrower does not obligate itself therein to do so; and (z) require that the Airframe or any Engine subject thereto be used in accordance with the limitations applicable to Borrower’s possession and use provided in this Mortgage and provide for the maintenance and inspection of the Aircraft in the same manner in all material respects as the applicable provisions of this Mortgage. No Permitted Lessee may sublease the Airframe or any Engine, except that a Permitted Manufacturer or Affiliate of Borrower that is a Permitted Lessee may sublease to any Permitted Lessee to whom a lease would be permitted under this Section 4.2; provided that (A) such sublease shall not permit any sub-subleasing of the Aircraft, the Airframe, or any Engine (and Borrower shall ensure that the same does not occur), (B) such sublease shall be assigned to Borrower to secure such Permitted Manufacturer’s obligations under its lease, and (C) Borrower shall comply, and shall cause such sublease to comply, with all requirements of this Section 4.2 as if such sublease were a direct lease from Borrower to the sublessee. Borrower shall reimburse Mortgagee for all of its reasonable out-of-pocket fees and expenses (including reasonable fees and disbursements of counsel) incurred in connection with any such lease. Except as otherwise provided herein and without in any way relieving Borrower from its primary obligation for the performance of its obligations under this Mortgage, Borrower may in its sole discretion permit a lessee to exercise any or all rights which Borrower would be entitled to exercise under Section 4.2 and Section 4.4, and may cause a lessee to perform any or all of Borrower’s obligations under Article 4, and Mortgagee agrees to accept actual and full performance thereof by a lessee in lieu of performance by Borrower.

As security for Borrower’s due and punctual payment and performance of all of its covenants and obligations in the Operative Agreements, Borrower hereby grants to Mortgagee a security interest in all of Borrower’s right, title, and interest in and to each Permitted Lease (and any related permitted sublease) having a term in excess of one year of any Aircraft, Airframe, or Engine, and all payments, including payments of rent, insurance proceeds (other than public liability insurance proceeds), and other amounts due or to become due thereunder. Borrower shall enter into a “Lease Assignment” in form and substance satisfactory to Mortgagee with respect to each Permitted Lease of the Airframe having a term of one or more years.

Mortgagee hereby agrees, and each Lender by acceptance of an Equipment Note agrees, for the benefit of each lessor, conditional seller, or secured party of any engine leased, purchased, or owned by Borrower or any Permitted Lessee subject to a lease, conditional sale, or other security agreement that Mortgagee, each Lender, and their respective successors and assigns will not acquire or claim, as against such lessor, conditional seller, or secured party, any right, title, or interest in any engine (other than an Engine) as the result of the installation of such engine on the Airframe at any time while such engine is subject to such lease, conditional sale, or other security agreement and owned by such lessor or conditional seller or subject to a security interest in favor of such secured party; provided, Borrower or any Permitted Lessee has received from any such lessor, secured party, or conditional seller in respect of any airframe leased,

purchased or owned by Borrower or any Permitted Lessee, a written agreement (which may be a copy of the lease, security agreement, conditional sale agreement, or other agreement covering such airframe), whereby such Person agrees that it will not acquire or claim any right, title, or interest in an Engine by reason of the installation of such Engine on any such airframe at any time while such Engine is subject to the Lien of this Mortgage.

(c) Operation and Use. Borrower shall not operate, use, or locate the Aircraft, the Airframe, or any Engine, or allow the Aircraft, the Airframe, or any Engine to be operated, used, or located, (1) in any area excluded from coverage by any insurance required by Section 4.6, except in the case of a requisition by the U.S. Government where Borrower obtains indemnity in lieu of such insurance from the U.S. Government, or insurance from the U.S. Government, against substantially the same risks and for at least the amounts of the insurance required by Section 4.6 covering such area, or (2) in any recognized area of hostilities unless covered in accordance with Section 4.6 by war risk insurance, or in either case unless the Aircraft, the Airframe, or any Engine is only temporarily operated, used, or located in such area as a result of an emergency, equipment malfunction, navigational error, hijacking, weather condition, or other similar unforeseen circumstance, so long as Borrower diligently and in good faith proceeds to remove the Aircraft from such area. Borrower shall not permit the Aircraft, the Airframe, or any Engine to be used, operated, maintained, serviced, repaired or overhauled (x) in violation of any Law binding on or applicable to such Aircraft, Airframe, or Engine or (y) in violation of any airworthiness certificate, license or registration of any Government Entity relating to the Aircraft, the Airframe, or any Engine, except (i) immaterial or non-recurring violations with respect to which corrective measures are taken promptly by Borrower or Permitted Lessee upon discovery thereof, or (ii) to the extent the validity or application of any such Law or requirement relating to any such certificate, license, or registration is being contested in good faith by Borrower or Permitted Lessee in any reasonable manner which does not involve any material risk of the sale, forfeiture, or loss of the Aircraft, the Airframe, or any Engine, any material risk of criminal liability or material civil penalty against Mortgagee or any Lender or impair in any material respect Mortgagee’s or any Lender’s interest in the Aircraft, the Airframe, or any Engine.

(d) Maintenance and Repair. At its own cost and expense, Borrower shall cause the Aircraft, the Airframe, and each Engine to be maintained, serviced, repaired, and overhauled in accordance with (1) maintenance standards required by, or substantially as stringent as those required by, the FAA (the “Maintenance Program”), so as (aa) to keep the Aircraft, the Airframe, and each Engine in as good operating condition as on the Closing Date, ordinary wear and tear excepted, (bb) in passenger configuration, and (cc) to keep the Aircraft in such operating condition as may be necessary to enable the applicable airworthiness certification of such Aircraft to be maintained under the regulations of the FAA or other Aviation Authority then having jurisdiction over the operation of the Aircraft (but in any event in accordance with the Maintenance Program), except during (x) temporary periods of storage in accordance with applicable regulations and applicable manufacturer guidelines, in which case Borrower undertakes to notify Mortgagee of any such storage and any change in the Maintenance Program as a result thereof, (y) maintenance and modification permitted hereunder, or (z) periods when the FAA or such other Aviation Authority has revoked or suspended the airworthiness

certificates for Similar Aircraft; and (2) except during periods when a Permitted Lease is in effect, the same standards as Borrower uses with respect to similar aircraft of similar size in its fleet operated by Borrower in similar circumstances and, during any period in which a Permitted Lease is in effect, the same standards used by the Permitted Lessee with respect to similar aircraft of similar size in its fleet and operated by the Permitted Lessee in similar circumstances. Borrower further agrees that the Aircraft, the Airframe, and Engines will be maintained, used, serviced, repaired, overhauled, or inspected in compliance with applicable Laws with respect to the maintenance of the Aircraft and in compliance with each applicable airworthiness certificate, license, and registration relating to the Aircraft, the Airframe, or any Engine issued by the Aviation Authority, other than minor or nonrecurring violations with respect to which corrective measures are taken upon discovery thereof and except to the extent Borrower or Permitted Lessee is contesting in good faith the validity or application of any such Law or requirement relating to any such certificate, license, or registration in any reasonable manner which does not create any material risk of sale, loss, or forfeiture of the Aircraft, the Airframe, or any Engine or the interest of Mortgagee or any Lender therein, or any material risk of criminal liability or material civil penalty against Mortgagee or any Lender. Borrower shall maintain or cause to be maintained the Aircraft Documents in English. Any maintenance, service, repair or overhaul that is intended to be accomplished with respect to the Airframe, any Engine, or any Part, as the case may be, shall be accomplished by Borrower or any Permitted Lessee or by Persons certificated by the FAA, JAA/EASA or any other applicable governmental or regulatory agency or authority having jurisdiction over such Person, and approved by the FAA, JAA/EASA or such other agency for the accomplishment of any such maintenance, service, repair or overhaul.

(e) Registration. On or as promptly as practicable after the Closing Date, Borrower shall cause the Aircraft to be duly registered in its name under the Transportation Code and cause (subject to the consent of the Airframe Manufacturer) the ownership interest of the Airframe and each Engine constituted by the Bills of Sale to be duly registered with the International Registry, and except as otherwise permitted by this Section 4.2(e) at all times thereafter shall cause the Aircraft to remain so registered. Borrower shall be entitled to register the Aircraft or cause the Aircraft to be registered in Taiwan, a Permitted Country or another country with the approval of Lenders (which approval shall not be unreasonably withheld) if: (1) such proposed change of registration is made in connection with a Permitted Lease; (2) Borrower and Permitted Lessee duly register with the appropriate Government Entity or such country the rights of Mortgagee in and to the Aircraft; (3) any import or export permits necessary to take the Aircraft into or out of such country and any exchange permits necessary to allow all payments provided for hereunder shall be in full force and effect; (4) all insurance provided for in this Mortgage shall be in full force and effect before, at the time of, and after such change in registration, and Mortgagee and each Lender shall receive a certificate of Borrower’s or Permitted Lessee’s insurance broker evidencing such insurance; (5) there are no procedural impediments to the repossession of the Aircraft greater than under United States law, and upon termination of any Permitted Lease, registration shall be terminable without material burden or delay; (6) there is no strict tort liability imposed on passive lenders, except such tort liability not of materially greater scope or magnitude than might be imposed on such passive lender or security trustee under the prevailing rule among the

states of the United States, and except liabilities that Borrower or a Permitted Lessee has agreed to insure against, which insurance is reasonably satisfactory to the Lenders and the Mortgagee; (7) such country imposes, or Borrower shall cause the Aircraft to be maintained in accordance with, aircraft maintenance standards approved by, or at least as stringent as those approved by, the FAA, the JAA/EASA, or the central civil aviation authority of Transport Canada, the United Kingdom, France, or Germany; (8) it shall not be necessary by reason of such re-registration or for purposes of enforcing remedies contained in this Mortgage or in the Loan Agreement or any Permitted Lease for Mortgagee or the Lenders to register or qualify to do business in such country; (9) the laws of such country require fair compensation, in currency freely convertible to U.S. dollars, for the loss of use of the Aircraft due to its requisition by the government of registry (unless Borrower or any Permitted Lessee provides insurance reasonably satisfactory to the Lenders covering the risk of requisition of use of the Aircraft by the government of such country so long as the Aircraft is registered under the laws of such country); (10) neither Mortgagee nor any Lender shall be subjected to any adverse tax consequences as a result of such re-registration for which Borrower is not required to indemnify such Person, unless Borrower has agreed to indemnify such Person therefore; (11) Mortgagee receives from Permitted Lessee and the Borrower an appropriate power of attorney required in connection with any repossession, deregistration or return of the Aircraft; and (12) Mortgagee receives an opinion of counsel (subject to customary assumptions and exceptions) satisfactory to Mortgagee (including as to such assumptions and exceptions), addressed to the Lenders and Mortgagee to the effect (i) that such country recognizes Borrower’s ownership interest in the Aircraft; (ii) that Borrower’s obligations, and Mortgagee’s rights and remedies, under the Mortgage are legal, valid, binding and enforceable under the laws of such jurisdiction (or the laws of the jurisdiction to which the laws of such jurisdiction would refer as the applicable governing law); (iii) that after giving effect to such change in registration, the Lien of the Mortgage on Borrower’s right, title, and interest in and to the Aircraft continues as valid a binding and duly-perfected first-priority security interest enforceable in such jurisdiction and all filing, recording, or other action necessary to protect the same shall have been accomplished (or, if such opinion cannot be given at the time of such proposed change in registration because such change in registration is not yet effective, (1) the opinion shall detail what filing, recording, or other action is necessary, and (2) Mortgagee receive a certificate from Borrower that all possible preparations to accomplish such filing, recording, and other action are done, and such filing, recording, and other action are accomplished, and a supplemental opinion to that effect shall be delivered to Mortgagee promptly after the effective date of such change in registration); (iv) as to the matters in the preceding clauses (3), (5), (6), (8) and (9) (unless Borrower or any Permitted Lessee provides the insurance contemplated by such clause (9)). Borrower shall reimburse Mortgagee and the Lenders for all of their reasonable out-of-pocket fees and expenses (including reasonable fees and disbursements of counsel) incurred in connection with any such change in registration and (v) as to such other matters as the Lenders shall require. Mortgagee and each Lender agrees to cooperate in good faith with Borrower to the extent necessary to enable it to effectuate such change in registration. Borrower shall also cause (A) this Mortgage to be duly recorded and at all times maintained of record as a first-priority perfected mortgage (subject to Permitted Liens) on the Aircraft, the Airframe, and each of the Engines and (B) the International Interest with respect to this Mortgage in the Airframe and each Engine to be duly registered on the International Registry as a first priority International Interest (except to the extent such perfection, priority or registration cannot be maintained solely as a result of the failure by Mortgagee to execute and deliver any necessary documents or consents).

(f) Markings. On or reasonably promptly after the Closing Date, Borrower will cause to be affixed to, and maintained in, the cockpit of the Airframe and on each Engine, in each case, in a clearly visible location, a placard of a reasonable size and shape bearing the legend: “Subject to a security interest in favor of Wells Fargo Bank Northwest, National Association, as Mortgagee.” Such placards may be removed temporarily, if necessary, in the course of maintenance of the Airframe or Engines and promptly replaced thereafter. If any such placard is damaged or becomes illegible, Borrower shall promptly replace it with a placard complying with the requirements of this Section 4.2(f).

4.3

Inspection.

(a) At all reasonable times, Mortgagee or its authorized representatives (the “Inspecting Parties”) may (not more than once every 12 months, unless an Event of Default exists, then such inspection right shall not be so limited) inspect the Aircraft and the Aircraft Documents.

(b) Any inspection of the Aircraft hereunder shall be limited to a visual, walk-around inspection, and shall not include the opening of any panels, bays, or other components of the Aircraft, and no such inspection shall interfere with Borrower’s or any Permitted Lessee’s maintenance or operation of the Aircraft, the Airframe, or any Engine.

(c) With respect to such rights of inspection, neither Mortgagee nor Agent shall have any duty or liability to make, or any duty or liability by reason of not making, any such visit, inspection or survey.

(d) Each Inspecting Party shall bear its own expenses in connection with any such inspection, unless an Event of Default exists, then Borrower shall reimburse each Inspecting Party for its reasonable out-of-pocket costs and expenses incurred in connection with any such inspection.

(e) Any Inspecting Party shall, upon request, be provided, at any such Inspecting Party’s cost and expense (unless at the time of such request an Event of Default exists), with copies of the reports and records of Borrower required to be maintained by the FAA or the regulatory agency or body of another jurisdiction in which the Aircraft is then registered which summarize the maintenance status of the Aircraft.

4.4

Replacement and Pooling of Parts; Alterations, Modifications, and Additions; Substitution of Engines.

(a) Replacement of Parts. Except as otherwise provided herein, Borrower, at its own cost and expense, will promptly replace (or cause to be replaced) all Parts that are

from time to time incorporated or installed in or attached to the Aircraft, and that become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair, or permanently rendered unfit for use for any reason whatsoever. In addition, Borrower, at its own cost and expense, may remove (or cause to be removed) in the ordinary course of business, fleet management, maintenance, service, repair, overhaul, or testing any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair, or permanently rendered unfit for use; provided, that, except as otherwise provided herein, Borrower will replace or cause the replacement of such Parts as promptly as practicable. All replacement parts (other than replacement parts installed in or attached to the Airframe or any Engine on a temporary basis) shall be owned by Borrower and shall be free and clear of all Liens, except for Permitted Liens and pooling arrangements to the extent permitted by Section 4.4(c), and shall be in good operating condition and (except in the case of replacement parts installed in or attached to the Airframe on a temporary basis) have a value, remaining useful life (without regard to hours and/or cycles to overhaul or replacement (as applicable)) and utility not less than the value, remaining useful life (without regard to hours and/or cycles to overhaul or replacement (as applicable)) and utility of the Parts replaced (assuming such replaced Parts were in the condition required hereunder).

(b) Removal of Parts. Except as otherwise provided herein, any Part at any time removed from the Airframe or any Engine shall remain subject to the Lien of this Mortgage, no matter where located, until it is replaced by a part that has been incorporated or installed in or attached to such Airframe or any Engine and that meets the requirements for replacement parts specified above. Except with respect to replacement parts installed in or attached to the Airframe or any Engine on a temporary basis, as soon as a replacement part is incorporated or installed in or attached to the Airframe or any Engine as provided in Section 4.4(a), without further act, (1) the replaced part shall thereupon be free and clear of all rights of Mortgagee and shall no longer be a Part hereunder, and (2) such replacement part shall become a Part hereunder and subject to this Mortgage and be part of such Airframe or Engine for all purposes hereof to the same extent as the Parts originally incorporated or installed in or attached to such Airframe or Engine.

(c) Pooling of Parts. Any Part removed from the Aircraft may be subjected by Borrower or a Permitted Lessee to a normal pooling arrangement customary in the airline industry and entered into in the ordinary course of business of Borrower or Permitted Lessee, provided, that the part replacing such removed Part shall be incorporated or installed in or attached to such Airframe or any Engine in accordance with Section 4.4(a) and Section 4.4(b) as promptly as practicable after the removal of such removed Part. In addition, any replacement part when incorporated or installed in or attached to the Airframe or any Engine may be owned by any third party, subject to a normal pooling arrangement, so long as Borrower or a Permitted Lessee, as promptly thereafter as reasonably possible, either (1) causes such replacement part to become subject to the Lien of this Mortgage, free and clear of all Liens except Permitted Liens, at which time such replacement part shall become a Part, or (2) replaces (or causes to be replaced) such replacement part by incorporating or installing in or attaching to the Aircraft a further replacement part owned by Borrower free and clear of all Liens except Permitted Liens and which shall become subject to the Lien of this Mortgage in accordance with Section 4.4(b).

(d) Alterations, Modifications, and Additions. Borrower shall make (or cause to be made) alterations and modifications in and additions to the Aircraft as may be required to be made from time to time to meet the applicable standards of the FAA or other Aviation Authority having jurisdiction over the operation of the Aircraft, to the extent made mandatory in respect of the Aircraft (a “Mandatory Modification”); provided, that Borrower or a Permitted Lessee may, in good faith and by appropriate procedure, contest the validity or application of any law, rule, regulation, or order in any reasonable manner which does not adversely affect in any material respect Mortgagee’s interest in the Aircraft and does not involve any material risk of sale, forfeiture, or loss of the Aircraft or the interest of Mortgagee or any Lender therein, or any material risk of material civil penalty or criminal liability being imposed on Mortgagee or any Lender. In addition, Borrower may make or permit to be made such alterations and modifications in and additions to the Airframe or any Engine (each an “Optional Modification”) as Borrower or a Permitted Lessee deems desirable in the proper conduct of its business, including removal of Parts which Borrower deems are obsolete or no longer suitable or appropriate for use in the Aircraft; provided, that no such Optional Modification shall (1) diminish the fair market value, utility, or useful life of the Aircraft or any Engine below its fair market value, utility, or useful life immediately before such Optional Modification (assuming the Aircraft or such Engine was in the condition required by this Mortgage immediately before such Optional Modification), or (2) cause the Aircraft to cease to have the applicable standard certificate of airworthiness. Except as otherwise provided herein, all Parts (other than Removable Parts) incorporated or installed in or attached to the Aircraft as a result of such Optional Modification shall, without further act, become subject to this Mortgage. Borrower or any Permitted Lessee may, at any time so long as the Airframe or any Engine is subject to the Lien of this Mortgage, remove any such Part (such Part being referred to herein as a “Removable Part”) from such Airframe or an Engine if (i) such Part is in addition to, and not in replacement of or in substitution for, any Part originally incorporated or installed in or attached to such Airframe or any Engine at the time of delivery thereof hereunder or any Part in replacement of, or in substitution for, any such original Part, (ii) such Part is not required to be incorporated or installed in or attached or added to such Airframe or any Engine pursuant to Section 4.2(d) or the first sentence of this Section 4.4(d), and (iii) such Part can be removed from such Airframe or any Engine without diminishing the fair market value, utility, or remaining useful life which such Airframe or any Engine would have had at the time of removal had such removal not been effected, assuming the Aircraft was otherwise maintained in the condition required by this Mortgage and such Removable Part had not been incorporated or installed in or attached to the Aircraft. No Removable Part shall be subject to the Lien of this Mortgage. Removable Parts may be leased from or financed by third parties other than Mortgagee. For the avoidance of any doubt, Mortgagee and Borrower acknowledge and agree that (x) any and all in-flight entertainment equipment installed in the Aircraft (whether before or after delivery thereof) shall be deemed to be a Removable Part for purposes of this Mortgage, (y) parts installed on the Engines (whether before or after delivery thereof) to increase the thrust setting of any such Engine shall be deemed to be a Removable Part for purposes of this Mortgage and (y) any winglets installed on the Aircraft shall not constitute a Removable Part.

(e) Substitution of Engines. Subject to the terms and conditions of this Section 4.4(e), (A) Borrower shall have the right at its option at any time for operational or fleet management purposes and so long as no Special Default or Event of Default shall exist, on at least five (5) Business Days’ prior notice to Mortgagee, to substitute for any Engine, and (B) if an Event of Loss to an Engine occurs under circumstances in which an Event of Loss to the Airframe has not occurred, Borrower shall within 90 days of the occurrence of such Event of Loss substitute for such Engine, a Replacement Engine, free and clear of Liens (other than Permitted Liens not of record). In such event, immediately upon the effectiveness of such substitution and without further act, (1) the replaced Engine shall thereupon be free and clear of all rights of Mortgagee and the Lien of this Mortgage and shall no longer be deemed an Engine hereunder, and (2) such Replacement Engine shall become subject to this Mortgage and be deemed part of the Aircraft for all purposes hereof to the same extent as was the replaced Engine. Such Replacement Engine shall be an engine manufactured by Engine Manufacturer that was placed into service after October 22, 1994 and that is the same model as the Engine being replaced thereby, or an improved model (but in any event the same model as the other Engine then subject to this Mortgage), and that is suitable for installation and use on the Airframe, and that has a value, utility, and remaining useful life (without regard to hours and cycles remaining until overhaul) similar to the Engine being replaced thereby (assuming that such Engine had been maintained in accordance with this Mortgage and was in the condition required hereunder). In connection with any such substitution, Borrower shall be required to fulfill the following conditions at Borrower’s sole cost and expense, and Mortgagee shall cooperate reasonably with Borrower to enable Borrower timely to satisfy such conditions:

(1) an executed counterpart of each of the following documents shall be delivered to Mortgagee:

(aa) furnish a certificate signed on the Borrower’s behalf by a duly authorized officer of the Borrower stating with respect to any Replacement Engine: (A) a description of the Engine suffering the Event of Loss, which shall be identified by manufacturer’s serial number; (B) a description of the Replacement Engine (including the manufacturer’s name and serial number); and (C) that on the date of the Mortgage Supplement relating to the Replacement Engine, each of the conditions specified in this Section 4.4(e) with respect to such Replacement Engine has been satisfied;

(cc) a full warranty (as to title) bill of sale, covering the Replacement Engine, executed by the former owner thereof in favor of Borrower (or, at Borrower’s option, other evidence of Borrower’s ownership of such Replacement Engine, reasonably satisfactory to Mortgagee), and Borrower shall cause (subject, if necessary, to the consent of the prior owner of the Replacement Engine) the ownership interest of the Replacement Engine constituted by such bill of sale (or other evidence) to be registered with the International Registry as a contract of sale;

(dd) Financing Statements covering the security interests created by this Mortgage (and any similar statements or other documents required to be filed or delivered pursuant to the laws of the jurisdiction in which such Aircraft may be registered) as are necessary to protect the security interests of Mortgagee in the Replacement Engine;

(ee) furnish the Mortgagee with evidence that such Replacement Engine was manufactured after October 22, 1994;

(ff) furnish a certificate signed by a qualified aircraft engineer (who may be an employee of Borrower) or appraiser reasonably acceptable to the Mortgagee certifying that such Replacement Engine is of the same as or improved model of the replaced Engine and has value and utility required by this Section 4.4(e); and

(gg) appropriate instruments collaterally assigning to the Mortgagee the benefits, if any, of all manufacturer’s and vendor’s warranties generally available and permitted to be assigned by the Borrower with respect to such Replacement Engine.

4.6

Insurance.

(a) Borrower’s Obligation to Insure. Borrower shall comply with, or cause to be complied with, each of the provisions of Annex B, which provisions are hereby incorporated by this reference as if set forth in full herein.

(b) Insurance for Own Account. Nothing in Section 4.6 shall limit or prohibit (a) Borrower from maintaining the policies of insurance required under Annex B with higher limits than those specified in Annex B, or (b) Mortgagee from obtaining insurance for its own account (and any proceeds payable under such separate insurance shall be payable as provided in the policy relating thereto); provided, that (i) Borrower may not insure the hull value of the Aircraft by an amount greater than twenty percent (20%) over the Insured Value (calculated as of the Closing Date) and (ii) no insurance may be obtained or maintained that would limit or otherwise adversely affect the coverage of or increase the cost of any insurance required to be obtained or maintained by Borrower pursuant to this Section 4.6 and Annex B.

(c) Indemnification by Government in Lieu of Insurance. During any period of requisition or transfer of the Aircraft or any part thereof by or to the U.S. Government or any other Government Entity, Mortgagee shall accept, in lieu of insurance against any risk with respect to the Aircraft described in Annex B, indemnification from, or insurance provided by, the U.S. Government, or upon Mortgagee’s written consent, other Government Entity, against such risk in an amount that, when added to the amount of insurance (including permitted self-insurance), if any, against such risk that Borrower (or any Permitted Lessee) may continue to maintain, in accordance with this Section 4.6, during the period of such requisition or transfer, shall be at least equal to the amount of insurance against such risk otherwise required by this Section 4.6.

(d) Government Insurance. Mortgagee shall accept, in lieu of insurance when required against war risk and allied perils with respect to the Aircraft described in Annex B, indemnification or insurance from the United States Government against war risks and allied perils in such amounts and on such terms that when added to the insurance maintained by Borrower, Borrower is in full compliance with the requirements of this Section 4.6.

(e) Application of Insurance Proceeds. As between Borrower and Mortgagee, all insurance proceeds received as a result of the occurrence of an Event of Loss to the Aircraft or any Engine under policies required to be maintained by Borrower pursuant to this Section 4.6 will be applied in accordance with Section 4.5(d). All proceeds of insurance required to be maintained by Borrower, in accordance with Section 4.6 and Section B of Annex B, in respect of any property damage or loss not constituting an Event of Loss with respect to the Aircraft, the Airframe, or any Engine will be held by Mortgagee and applied to pay (or to reimburse Borrower) for repairs or for replacement property, and any balance remaining after such repairs or replacement with respect to such damage or loss shall be paid over to, or retained by, Borrower.

4.7

Merger of Borrower.

(a) In General. Borrower shall not consolidate with or merge into any other Person under circumstances in which Borrower is not the surviving corporation, unless:

(1) such Person is organized, existing, and in good standing under the Laws of the United States, any state of the United States, or the District of Columbia, and, upon consummation of such transaction, such Person will be a U.S. Air Carrier with respect to which, absent a change in law or court interpretation, Mortgagee will be entitled to the benefits of Section 1110;

(2) such Person executes and delivers to Mortgagee a duly authorized, legal, valid and binding agreement, reasonably satisfactory in form and substance to Mortgagee, containing an effective assumption by such Person of the due and punctual performance and observance of each covenant, agreement, and condition in the Operative Agreements to be performed or observed by Borrower; and

(3) such Person, immediately after giving effect to such transaction, shall have a tangible net worth of not less than (aa) Borrower’s tangible net worth (determined in each case in accordance with GAAP) as of the Closing Date or (bb) Borrower’s tangible net worth (determined in each case in accordance with GAAP) immediately prior to such transaction.

(b) Effect of Merger. Upon any such consolidation or merger of Borrower with any Person in accordance with this Section 4.7, such Person will succeed to, and be substituted for, and may exercise every right and power of, Borrower under the Operative Agreements with the same effect as if such Person had been named as “Borrower” therein. No such consolidation or merger shall have the effect of releasing Borrower or such Person from any of the obligations, liabilities, covenants, or undertakings of Borrower under the Mortgage.

5. EVENTS OF DEFAULT; REMEDIES

5.1

9. SUCCESSOR AND SEPARATE TRUSTEES

9.1

Resignation of Mortgagee; Appointment of Successor.

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

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

(c) Any successor institution acting as Mortgagee, however appointed, shall be a bank or trust company that has its principal place of business in the United States of America (or, failing such standards, a Lender (subject to appropriate modifications to this Mortgage with respect to withholding taxes)), and that has (or whose obligations under the Operative Agreements are guaranteed by an affiliated entity that has) a combined capital and surplus of at least $250,000,000, if such an institution is then willing, able, and legally qualified to perform the duties of Mortgagee hereunder upon reasonable or customary terms.

(d) Any corporation into which the institution acting as Mortgagee is merged or converted or with which it is consolidated, or any corporation resulting from any merger, conversion, or consolidation to which the institution acting as Mortgagee is a party, or any corporation to which substantially all the corporate trust business of the institution acting as Mortgagee is transferred, shall, subject to Section 9.1(c), be a successor Mortgagee and Mortgagee under this Mortgage without further act.

(e) Borrower consents to any change in the identity of the Mortgagee on the International Registry occasioned by provisions of this Section 9.1, and if required by the International Registry to reflect such change, will provide its consent thereto.

9.2

Appointment of Additional and Separate Trustees.

If Borrower has not taken any action requested of it under this Section 9.2(a) that is permitted or required by its terms within 15 days after receiving a written request from Mortgagee to do so, or if an Event of Default exists, Mortgagee may act under the foregoing provisions of this Section 9.2(a) without Borrower’s concurrence, and Borrower hereby irrevocably appoints (which appointment is coupled with an interest) Mortgagee as Borrower’s agent and attorney-in-fact to act for Borrower under the foregoing provisions of this Section 9.2(a) in either of such contingencies. In such capacity, Mortgagee may 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. If any additional or separate trustee appointed under this Section 9.2(a) dies, becomes incapable of acting, resigns, or is moved, all the assets, property, rights, powers, trusts, duties, and obligations of such additional or separate trustee shall revert to Mortgagee until a successor additional or separate trustee is appointed as provided in this Section 9.2(a).

(b) No additional or separate trustee shall be entitled to exercise any of the rights, powers, duties, and obligations conferred upon Mortgagee in respect of the custody, investment, and payment of money, and any such additional or separate trustee shall promptly pay over to Mortgagee all money that such additional or separate trustee receives from or constituting part of the Collateral or otherwise payable to Mortgagee under any Operative Agreement. All other rights, powers, duties, and obligations conferred or imposed upon any additional or separate trustee shall be exercised or performed by 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 Mortgagee incompetent or unqualified to perform such act, in which event such rights, powers, duties, and obligations (including the holding of title to all or part of the Collateral in any such jurisdiction) shall be exercised and performed by such additional or separate trustee. No additional or separate trustee shall take any discretionary action except on the instructions of Mortgagee or a Majority in Interest of the Lenders. No trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder, except that Mortgagee shall be liable for the consequences of its lack of reasonable care in selecting, and Mortgagee’s own actions in acting with, any additional or separate trustee. Each additional or separate trustee appointed pursuant to this Section 9.2 shall be subject to, and shall have the benefit of, Articles 5 through 9 and Article 11 insofar as they apply to Mortgagee. The powers of any additional or separate trustee appointed pursuant to this Section 9.2 shall not in any case exceed those of Mortgagee hereunder.

(c) If at any time Mortgagee deems 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 Lenders, or if Mortgagee is requested to do so in writing by a Majority in Interest of the Lenders, Mortgagee and (upon Mortgagee’s written request) Borrower shall execute and deliver an indenture supplemental hereto and all other instruments and agreements necessary or proper to remove any additional or separate trustee. Mortgagee may act on behalf of Borrower under this Section 9.2(c) when and to the extent it could so act under Section 9.2(a).

Obligations or the Guaranteed Documents, by any other guarantee or other obligations, or by any other circumstance or condition (whether or not Guarantor or Borrower shall have any knowledge or notice thereof), including, without limitation: (1) any termination, amendment, modification, or other change in, or supplement to, any of the Guaranteed Documents or any other agreement, or to the Aircraft or any part thereof, or any assignment, mortgage, or transfer thereof, or any leasing or subleasing of or any re-registration of the Aircraft, or any furnishing or acceptance of additional security, or release of any security, for the obligations of Borrower under the Guaranteed Documents, or the failure of any security or any failure to perfect any interest in any collateral given by Borrower under the Guaranteed Documents; (2) any failure, omission, or delay on the part of any Person to conform or comply with any term of any Guaranteed Document or any other agreement, including failure to give notice to Guarantor of the occurrence of a Default; (3) any waiver of the payment, performance, or observance of any of the obligations, conditions, covenants, or agreements contained in any Guaranteed Document or any other agreement or any other waiver, consent, extension, indulgence, compromise, settlement, release, or other action or inaction under or in respect of any Guaranteed Document, or any exercise or nonexercise of any right or remedy under any Guaranteed Document or any obligation or liability of Borrower or any Guaranteed Party, or any exercise or nonexercise of any right, remedy, power, or privilege under or in respect of any Guaranteed Document or any such obligation or liability; (4) any extension of time for payment or performance of any Obligation; (5) the exchange, modification, substitution, or surrender of any collateral; (6) any failure, omission, or delay on the part of any Guaranteed Party to enforce, assert, or exercise any right, power, or remedy conferred on it in connection with any Guaranteed Document, or any other action on the part of any Guaranteed Party; (7) any voluntary or involuntary bankruptcy, insolvency, assignment for the benefit of creditors, receivership, conservatorship, custodianship, liquidation, marshalling of assets and liabilities, or similar proceeding with respect to Borrower, Guarantor, or any other Person or any of their respective properties or creditors, or the disaffirmance in whole or in part of any of the Guaranteed Documents in any such proceeding, or any action taken by any trustee or receiver or by any court in any such proceeding; (8) any limitation on Borrower’s liability or obligations (or the liabilities and obligations of any other Person) or any discharge, termination, cancellation, frustration, irregularity, invalidity, or unenforceability, in whole or in part, of any of the Guaranteed Documents or any other agreement; (9) any defect in the title, compliance with specifications, condition, design, operation, or fitness for use of the Aircraft, or any damage to or loss or destruction of the Aircraft, or any interruption or cessation of the use of the Aircraft for any reason (including any force majeure and any act of a governmental or military authority); (10) any merger or consolidation of Borrower or Guarantor into or with any other corporation, or any sale, lease, or other transfer of any of the assets of Borrower or Guarantor to any other Person or any change in the ownership of Guarantor or Borrower or in the control of any such owner; (11) to the extent permitted by law, any release or discharge, by operation of law, of Guarantor from the performance or observance of any obligation, covenant, or agreement contained in this Guarantee; and (12) any other condition or circumstance which might otherwise constitute a legal or equitable discharge, release, or defense of a surety or guarantor, or which might otherwise limit recourse against Guarantor, including any discharge, release, defense, or limitation arising out of any laws of the United States of America or any state thereof or any other Government Entity having authority thereover which would exempt, modify, or delay the due or punctual payment and performance of the obligations of Guarantor hereunder (the obligations of Guarantor hereunder not being dischargeable except by payment or performance). No failure or delay in exercising any right under this Guarantee shall operate as a waiver thereof, nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right of any Guaranteed Party under this Guarantee or the Guaranteed Documents.

(c) Guarantee of Payment and Performance. This Guarantee is a continuing guarantee of payment and performance and not merely of collection, and Guarantor waives any right to require that any action against Borrower or any other Person or any collateral or security be taken or exhausted before action is taken against Guarantor. No Guaranteed Party shall be required (1) to file suit or to proceed to obtain or assert a claim against Borrower for the Obligations, (2) to make any effort at collection of the Obligations from Borrower, (3) to foreclose against or seek to realize upon any present or future security for the Obligations, (4) to file suit or to proceed to obtain or assert a claim for personal judgment against any other Person liable for the Obligations, or to make any effort at collecting the Obligations from any such other Person, or to exercise or assert any other right or remedy to which any Guaranteed Party is or becomes entitled in connection with the Obligations or any security or other guarantee therefor, or (5) to assert or to file any claim against the assets of Borrower or any other guarantor or any other Person liable for the Obligations, or any part thereof, either before or as a condition to enforcing Guarantor’s liability under this Guarantee or to require Guarantor to pay or perform the Obligations at any time thereafter.

(d) Waiver. Guarantor hereby waives diligence, presentment, demand, protest, and notice of any kind whatsoever with respect to this Guarantee or the Obligations, including (1) notice of acceptance of this Guarantee, notice of nonpayment or nonperformance of any of the Obligations, and notice of a Default; (2) any requirement to exhaust any remedies exercisable upon a default under any Guaranteed Document or other agreement; (3) any notice of any sale, transfer, or other disposition of any right or title to or interest in the Aircraft or any part thereof; and (4) any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge, release, or defense of a guarantor or surety or which might otherwise limit recourse against Guarantor.

(e) Termination. Guarantor’s obligations under this Section 1 shall terminate (subject to reinstatement under Section 3) when the Obligations have been irrevocably paid and performed in full.

2. Rights Limited to Guaranteed Parties. This Guarantee shall not create any right in any Person except the Guaranteed Parties (and their permitted successors and assigns), and shall not be construed in any respect to be a contract in whole or in part for the benefit of any other Person.

3. Bankruptcy, etc. If at any time all or any part of any payment or performance theretofore applied to any of the Obligations is or must be rescinded or returned for any reason whatsoever (including the bankruptcy, insolvency, or reorganization of Borrower), such Obligations shall, for purposes of this Guarantee, to the extent rescinded or returned, be deemed to have continued in existence, notwithstanding such application by any Guaranteed Party, and this Guarantee shall continue to be effective or be reinstated, as the case may be, as to such Obligations

all as though such application by any Guaranteed Party had not been made. If an event permitting the declaration of default under a Guaranteed Document exists at any time, and such declaration of default is prevented by the pendency against Borrower or any other Person of a case or proceeding under a bankruptcy or insolvency law, then for purposes of this Guarantee and Guarantor’s obligations hereunder, such Guaranteed Document shall be deemed to have been declared in default with the same effect as if such Guaranteed Document had been enforceable in accordance with the terms thereof, and Guarantor shall forthwith pay the amounts due hereunder as specified by any Guaranteed Party, any interest thereon, and any other amounts guaranteed hereunder, without further notice or demand.

4. Subrogation. Guarantor hereby irrevocably and unconditionally waives any and all rights it may have or obtain, by reason of the performance of the terms and provisions of this Guarantee, to be subrogated to the rights and privileges of any Guaranteed Party against Borrower, or against any collateral security or guarantee or right of offset held by any Guaranteed Party for the payment of the Obligations pursuant to the Guaranteed Documents or otherwise. No payment or performance hereunder by Guarantor shall give rise to any claim of Guarantor against any of the Guaranteed Parties; provided, that this sentence shall not prevent Guarantor from being subrogated to any claim available to Borrower.

5. Amendments and Other Actions. Any Guaranteed Party may, in its discretion, and without affecting Guarantor’s absolute, continuing, and unconditional liability under this Guarantee, agree to amendments, modifications, or supplements to the Guaranteed Documents, give or withhold consents, waivers, or approvals, and exercise or refrain from exercising rights under the Guaranteed Documents.

6. Assignment. Any Guaranteed Party may at any time sell, assign, transfer, or otherwise dispose of its interest in all or any part of this Guarantee or the Guaranteed Documents and in the property and interests subject hereto and thereto, subject to any limitations and conditions thereon in any such Guaranteed Document. To the extent of the interest acquired by it, any purchaser, assignee, transferee, or other party so acquiring any Guaranteed Party’s interest shall have the same rights as such assigning Guaranteed Party hereby and shall be deemed and declared a “Guaranteed Party” hereunder. Guarantor shall not assign any of its rights or obligations hereunder, including any claim arising by subrogation.

7. Written Changes Only. No amendment, waiver, or consent under the terms of this Guarantee shall be effective unless evidenced by an instrument in writing signed by Guarantor and each Guaranteed Party.

8. Payments. All payments by Guarantor hereunder shall be made in the United States in U.S. dollars and in immediately available funds, and otherwise as provided in the Guaranteed Documents pursuant to which the relevant Obligations are created. Section 9.3(a) of the Loan Agreement shall apply to payments made by Guarantor hereunder, mutatis mutandis, as if references therein to “Borrower” were references to Guarantor; provided, that the provisions of Section 9.3(a) shall not be applied more than once with respect to any payment obligation of Borrower that is paid by Guarantor hereunder.

9. Expenses. The Guarantor further agrees to pay any and all expenses (including, without limitation, all fees and disbursements of counsel) which are reasonably incurred by any Guaranteed Party in successfully enforcing or collecting any or all of the Obligations and/or successfully enforcing or collecting under this Guarantee.

10. Representations, Warranties, and Covenants. Guarantor hereby represents, warrants, and covenants to the Guaranteed Parties as follows:

(a) Organization; Qualification. Guarantor is a corporation validly existing and in good standing under the Laws of Nevada, and has the corporate power and authority to conduct the business in which it is currently engaged and to own or hold under lease its properties and to enter into and perform its obligations under this Guarantee. Guarantor is duly qualified to do business as a foreign corporation in good standing in each jurisdiction in which the nature and extent of the business conducted by it, or the ownership of its properties, requires such qualification, except where the failure to be so qualified does not constitute or would not give rise to a Materially Adverse Change to Guarantor

(b) Authorization; Compliance. The execution and delivery by Guarantor of, and performance by Guarantor of its obligations under, this Guarantee has been duly authorized by all necessary corporate action on the part of Guarantor.

(c) No Violation. Guarantor’s execution and delivery of, and performance of its obligations under, this Guarantee do not (1) violate any provision of Guarantor’s articles of incorporation or by-laws, (2) violate any Law applicable to or binding on Guarantor, or (3) violate or constitute any default under, or result in the creation of any Lien under, any lease, loan or other agreement to which Guarantor is a party or by which Guarantor or any of its properties is bound.

(d) Approvals. Guarantor’s execution and delivery of, and performance of its obligations under, this Guarantee do not require the consent or approval of, the giving of notice to, the registration with, the recording or filing of any documents with, or the taking of any other action in respect of (1) any trustee or other holder of any debt of Guarantor, or (2) any Government Entity.

(e) Valid and Binding Guarantee. This Guarantee has been duly authorized, executed, and delivered by Guarantor and this Guarantee constitutes legal, valid, and binding obligations of Guarantor enforceable against Guarantor in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, and other similar Laws affecting the rights of creditors generally or by general principles of equity.

(f) No Litigation. Except as set forth in Guarantor’s Annual Report on Form 10-K, Quarterly Report on Form 10-Q or Current Report on Form 8-K filed with the SEC on or prior to December 31, 2006, no action, claim or proceeding is now pending or, to Guarantor’s Actual Knowledge, threatened, against Guarantor before any Government Entity, that is reasonably likely to be determined adversely to Guarantor and if determined adversely to Guarantor would result in a Materially Adverse Change.

11. Covenants. The Guarantor hereby covenants and agrees with each Guaranteed Party that, from and after the date of this Guarantee until the Obligations are irrevocably performed and paid in full:

(a) It will (i) preserve and maintain its legal existence and all of its material rights, privileges and franchises, (ii) conduct its business in all material respects in accordance with all applicable Laws and regulations binding on it and its operations or assets, and (iii) promptly provide the Guaranteed Parties with such financial and other information concerning its affairs as the Guaranteed Parties or any of them, as the case may be, may from time to time reasonably request in connection with the transactions contemplated by this Guarantee and any other Operative Document.

(b) It shall provide to the Mortgagee, copies of its (x) audited financial statements for its financial year ended as at December 31, 2006 and for each financial year thereafter as soon as they are available but in any event not later than 120 days after the close of the relevant period and (y) unaudited financial statements for each quarterly period as soon as they are available but in any event not later than sixty (60) days after the close of the relevant period. Each financial statement provided hereunder shall have been prepared in accordance with GAAP and each annual financial statement shall be accompanied by a certificate of the Guarantor, signed by the principal financial officer of the Guarantor, stating that, based on an examination sufficient to enable such officer to make an informed statement, no Default under the Guaranteed Documents exists or, if such is not the case, specifying such Default and its nature, when it occurred and the steps being taken by Holdings with respect thereto. Notwithstanding the foregoing to the contrary, so long as Guarantor is subject to, and complying with, the reporting requirements under the Securities and Exchange Act of 1934, Guarantor’s obligations under this Section 11(b) shall be suspended.

(c) It shall maintain its corporate existence under and in compliance with all applicable Laws, and it may not consolidate with or merge into another Person under circumstances in which Guarantor is not the surviving corporation, unless:

(1) such Person is organized, existing, and in good standing under the Laws of the United States, any state of the United States, or the District of Columbia;

(2) such Person executes and delivers to Mortgagee a duly authorized, legal, valid and binding agreement, reasonably satisfactory in form and substance to Mortgagee, containing an effective assumption by such Person of the due and punctual performance and observance of each covenant, agreement, and condition in this Guarantee to be performed or observed by the Guarantor; and

(3) such Person, immediately after giving effect to such transaction, shall have a tangible net worth of not less than (aa) Guarantor’s tangible net worth (determined in each case in accordance with GAAP) as of the Closing Date or (bb) Guarantor’s tangible net worth (determined in each case in accordance with GAAP) immediately prior to such transaction

Upon any such consolidation or merger of Guarantor with any Person in accordance with this Section 11(c), such Person will succeed to, and be substituted for, and may exercise every right and power of, Guarantor under this Guarantee with the same effect as if such Person had been named as “Guarantor” therein. No such consolidation or merger shall have the effect of releasing Guarantor or such Person from any of the obligations, liabilities, covenants, or undertakings of Guarantor under this Guarantee. Guarantor shall provide written notice to Mortgagee of any such consolidation or merger of Guarantor with any Person in accordance with this Section 11(c) at least thirty (30) days’ prior to the consummation thereof.

(c) At its own expense, it shall execute, acknowledge, and deliver (or shall cause to be executed, acknowledged, and delivered) all such further agreements, instruments, certificates, or other documents, and shall do and cause to be done such further things, as any Guaranteed Party reasonably requests in connection with the administration of, or to carry out more effectively the purposes of, or to assure and confirm better to such Guaranteed Party the rights and benefits to be provided under, this Guarantee.

12.

GUARANTOR HEREBY AGREES THAT SERVICE UPON IT, OR ANY OF ITS AGENTS, IN EACH CASE IN ACCORDANCE WITH THIS SECTION 12(C), SHALL CONSTITUTE VALID AND EFFECTIVE PERSONAL SERVICE UPON GUARANTOR, AND GUARANTOR HEREBY AGREES THAT THE FAILURE OF ANY OF ITS AGENTS TO GIVE ANY NOTICE OF SUCH SERVICE TO GUARANTOR SHALL NOT IMPAIR OR AFFECT IN ANY WAY THE VALIDITY OF SUCH SERVICE ON GUARANTOR OR ANY JUDGMENT RENDERED IN ANY ACTION OR PROCEEDING BASED THEREON.

(d) GUARANTOR HEREBY IRREVOCABLY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, AND AGREES NOT TO ASSERT, BY WAY OF MOTION, AS A DEFENSE, OR OTHERWISE, IN ANY LEGAL ACTION OR PROCEEDING BROUGHT HEREUNDER IN ANY OF THE ABOVE-NAMED COURTS, THAT SUCH ACTION OR PROCEEDING IS BROUGHT IN AN INCONVENIENT FORUM, THAT VENUE FOR THE ACTION OR PROCEEDING IS IMPROPER, OR THAT THIS GUARANTEE MAY NOT BE ENFORCED IN OR BY SUCH COURTS.

(e) GUARANTOR HEREBY WAIVES ITS RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION IN ANY COURT IN ANY JURISDICTION BASED UPON OR ARISING OUT OF OR RELATING TO THE OPERATIVE AGREEMENTS.
