WHEREAS, pursuant to this Agreement the Company wishes to finance each of the Aircraft hereunder;

WHEREAS, pursuant to the Basic Pass Through Trust Agreement and each of the Trust Supplements set forth in Schedule II hereto, and concurrently with the execution and

delivery of this Agreement, separate grantor trusts (collectively, the “Pass Through Trusts” and, individually, a “Pass Through Trust”) have been created to facilitate certain of the transactions contemplated hereby, including, without limitation, the issuance and sale of pass through certificates pursuant thereto (collectively, the “Certificates”) to provide for a portion of the financing of the Aircraft contemplated hereby;

WHEREAS, the Company has entered into the Underwriting Agreement, dated as of January 31, 2018 (the “Underwriting Agreement”) with the Underwriters named therein (the “Underwriters”), which provides that the Company will cause the Pass Through Trustee under the Class AA Pass Through Trust (the “Class AA Pass Through Trustee”) and the Pass Through Trustee under the Class A Pass Through Trust (the “Class A Pass Through Trustee”) to issue and sell the Class AA Certificates and the Class A Certificates, respectively, to the Underwriters on the Issuance Date;

WHEREAS, concurrently with the execution and delivery of this Agreement, (i) National Australia Bank Limited, acting through its New York Branch (the “ Liquidity Provider”), has entered into two revolving credit agreements, one each for the benefit of the Certificateholders of the Class AA and Class A Pass Through Trusts, in each case, with the Subordination Agent, as agent for the Pass Through Trustee on behalf of each such Pass Through Trust (each such revolving credit agreement with the Liquidity Provider, a “Liquidity Facility”) and (ii) the Pass Through Trustees, the Liquidity Provider and the Subordination Agent have entered into the Intercreditor Agreement, dated as of the date hereof (the “Intercreditor Agreement”).

NOW, THEREFORE, in consideration of the foregoing premises and the mutual agreements herein contained and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Financing of Aircraft. (a) The Company confirms that (i) it currently owns the Delivered Aircraft that were delivered to it by the Manufacturer prior to the date hereof and (ii) it has entered into the Aircraft Purchase Agreements with the Manufacturer pursuant to which the Company has agreed to purchase, and the Manufacturer has agreed to deliver, the New Aircraft subject thereto in the months specified in Schedule I hereto, all on and subject to terms and conditions specified in such Aircraft Purchase Agreement. The Company agrees to finance the Aircraft in the manner provided herein, all on and subject to the terms and conditions hereof and of the relevant Financing Agreements.

(b) In furtherance of the foregoing, the Company agrees to give the parties hereto, the Depositary and each of the Rating Agencies not less than one Business Day’s prior notice substantially in the form of Exhibit A hereto (a “Closing Notice”) of the scheduled closing date (the “Scheduled Closing Date”) (or, in the case of a substitute Closing Notice under

Section 1(e) or (f) hereof, one Business Day’s prior notice) in respect of the financing of each Aircraft under this Agreement, which notice shall:

(i) specify the Scheduled Closing Date of such Aircraft (which shall be a Business Day before the Cut-off Date and, except as provided in Section 1(f) hereof, the date (the “Funding Date”) on which the financing therefor in the manner provided herein shall be consummated);

(ii) instruct each Pass Through Trustee being requested to purchase Equipment Notes pursuant to such Closing Notice (the “Applicable Pass Through Trustees”) to enter into the Participation Agreement included in the Financing Agreements with respect to such Aircraft in such form and at such a time on or before the Funding Date specified in such Closing Notice and to perform its obligations thereunder;

(iii) instruct each of the Class AA and Class A Pass Through Trustees to instruct the relevant Escrow Agent to provide a Notice of Purchase Withdrawal to the Depositary with respect to the Equipment Notes to be issued to such Pass Through Trustee in connection with the financing of such Aircraft (except in the case of any such financing on the Issuance Date); and

(iv) specify the aggregate principal amount of each series of Equipment Notes, if any, to be issued, and purchased by the Applicable Pass Through Trustees, in connection with the financing of such Aircraft scheduled on such Funding Date (which shall in all respects comply with the Required Terms).

Notwithstanding the foregoing, in the case of any Aircraft to be financed hereunder on the Issuance Date, the Closing Notice therefor may be delivered to the parties hereto on the Issuance Date.

(c) Upon receipt of a Closing Notice, the Applicable Pass Through Trustees shall, and shall cause the Subordination Agent to, enter into and perform their respective obligations under the Participation Agreement specified in such Closing Notice, provided that such Participation Agreement and the Indenture to be entered into pursuant to such Participation Agreement shall be in the forms thereof annexed hereto in all material respects and, if modified in any material respect, as to which Rating Agency Confirmation shall have been obtained from each Rating Agency by the Company (to be delivered by the Company to the Applicable Pass Through Trustees on or before the

relevant Funding Date, it being understood that if Rating Agency Confirmation shall have been received with respect to any Financing Agreements and such Financing Agreements are utilized for subsequent Aircraft (or Substitute Aircraft) without material modifications, no additional Rating Agency Confirmation shall be required); provided, however, that the relevant Financing Agreements as executed and delivered shall not vary the Required Terms. Notwithstanding the foregoing, an Indenture may be modified to the extent required for the issuance of Equipment Notes pursuant to Section 4(a)(vi) of this Agreement, subject to the terms of such Section and Section 9.1(c) or 9.1(d) of the Intercreditor Agreement, whichever may be applicable. The Company shall pay the reasonable costs and expenses of the Rating Agencies in connection with obtaining any such Rating Agency Confirmation. With respect to each Aircraft, the Company shall cause WTNA (or such other person that meets the eligibility requirements to act as loan trustee under the Indenture) to execute as Loan Trustee the Financing Agreements relating to such Aircraft to which such Loan Trustee is intended to be a party, and shall concurrently therewith execute such Financing Agreements to which the Company is intended to be a party and perform its respective obligations thereunder. Upon the request of any Rating Agency, the Company shall deliver or cause to be delivered to such Rating Agency a true and complete copy of each Financing Agreement relating to the financing of each Aircraft together with a true and complete set of the closing documentation (including legal opinions) delivered to the related Loan Trustee, Subordination Agent and Pass Through Trustee under the related Participation Agreement.

(d) The Company agrees that all Equipment Notes issued pursuant to any Indenture shall initially be registered in the name of the Subordination Agent on behalf of the Applicable Pass Through Trustees (or, in the case of any Additional Series Equipment Notes, on behalf of the Additional Series Pass Through Trustee with respect to the corresponding Additional Series Pass Through Certificates).

(e) If after giving any Closing Notice, there shall be a delay in the delivery of the Aircraft referred to therein, or if on the Scheduled Closing Date of the Aircraft referred to therein the financing thereof in the manner contemplated hereby shall not be consummated for whatever reason, the Company shall give the parties hereto and the Depositary prompt notice thereof. Concurrently with the giving of such notice of postponement or subsequently, the Company shall give the parties hereto and the Depositary a substitute Closing Notice specifying

the date to which the financing of such Aircraft (or of another Aircraft of the same model in lieu thereof) shall have been re-scheduled (which shall be a Business Day before the Cut-off Date on which the Escrow Agents shall be entitled to withdraw one or more Deposits under each of the applicable Deposit Agreements to enable each of the Class AA and Class A Pass Through Trustees to fund its purchase of the related Equipment Notes). Upon receipt of any such notice of postponement, each Applicable Pass Through Trustee shall comply with its obligations under Section 5.01 of each of the Trust Supplements and thereafter the financing of such Aircraft, as specified in such substitute Closing Notice, shall take place on the re-scheduled Closing Date therefor (all on and subject to the terms and conditions of the relevant Financing Agreements) unless further postponed as provided herein.

(f) Anything in this Section 1 to the contrary notwithstanding, the Company shall have the right to accept delivery of an Aircraft (including a Delivered Aircraft) under the applicable Aircraft Purchase Agreement on the Delivery Date thereof by utilization of bridge financing of such Aircraft (including cash provided by the Company) and thereafter give the parties hereto and the Depositary a Closing Notice specifying a Funding Date (i) in the case of any New Aircraft, not later than 90 days after the Delivery Date of such New Aircraft, (ii) in the case of any Delivered Aircraft, not later than 60 days after the Issuance Date and (iii) in the case of any Aircraft, not later than the Cut-off Date, and otherwise complying with the provisions of Section 1(b) hereof. All other terms and conditions of this Agreement shall apply to the financing of any such Aircraft on the re-scheduled Funding Date therefor except the related Financing Agreements shall be amended to reflect the original delivery of such Aircraft to the Company.

(g) If the scheduled delivery date from the Manufacturer for any New Aircraft is delayed more than 30 days beyond the last day of the month set forth opposite such New Aircraft under the heading “Scheduled Delivery Month” in Schedule I hereto, the Company may identify for delivery a substitute aircraft therefor meeting the following conditions (a “Substitute Aircraft”): (i) a Substitute Aircraft must be of the same model as the New Aircraft being replaced and (ii) the Company shall be obligated to obtain Rating Agency Confirmation in respect of the replacement of any New Aircraft by Substitute Aircraft. Upon the satisfaction of the conditions set forth above with respect to a Substitute Aircraft, the New Aircraft to be replaced shall cease to be subject to this Agreement and all

rights and obligations of the parties hereto concerning such New Aircraft shall cease, and such Substitute Aircraft shall become and thereafter be subject to the terms and conditions of this Agreement to the same extent as such New Aircraft.

(h) The Company shall have no liability for the failure of the Pass Through Trustees to purchase Equipment Notes with respect to any Aircraft or Substitute Aircraft.

(i) Anything herein to the contrary notwithstanding, the Company shall not have the right, and shall not be entitled, at any time to request the issuance of Equipment Notes of any series to the Class AA or Class A Pass Through Trustee in an aggregate principal amount in excess of the amount of the Deposits then available for withdrawal by the Escrow Agent under and in accordance with the provisions of the related Deposit Agreement.

SECTION 2. Conditions Precedent. The obligation of the Applicable Pass Through Trustees to enter into, and to cause the Subordination Agent to enter into, any Participation Agreement as directed pursuant to a Closing Notice and to perform its obligations thereunder is subject to satisfaction of the following conditions:

(a) no Triggering Event shall have occurred; and

(b) the Company shall have delivered a certificate to each such Pass Through Trustee and the Liquidity Provider stating (i) that such Participation Agreement and the other Financing Agreements to be entered into pursuant to such Participation Agreement do not vary the Required Terms and (ii) that any substantive modification of such Financing Agreements from the forms of Financing Agreements attached to this Agreement do not materially and adversely affect the Certificateholders or the Liquidity Provider, and such certification shall be true and correct.

Anything herein to the contrary notwithstanding, the obligation of each Pass Through Trustee to purchase Equipment Notes shall terminate on the Cut-off Date.

(v) the Company agrees to provide written notice to each of the parties hereto of the occurrence of the Cut-off Date no later than one Business Day after the date thereof, such notice to refer specifically to the Pass Through Trustee’s obligation to assign, transfer and deliver all of its right, title and interest to the Trust Property (as defined in each Pass Through Trust Agreement) to the trustee of the Related Trust (as defined in each Pass Through Trust Agreement) in accordance with Section 7.01 of each of the Trust Supplements;

(vi) the Company shall not repay and re-issue any Series A Equipment Notes or issue (or repay and reissue) any Additional Series Equipment Notes pursuant to any Indenture, unless it shall have obtained written confirmation from each Rating Agency that the reissuance or issuance of such Equipment Notes, as the case may be, will not result in (1) a reduction of the rating for any Class of Certificates then rated by such Rating Agency that will remain outstanding below the then current rating for such Class of Certificates or (2) a withdrawal or suspension of the rating of any Class of Certificates then rated by such Rating Agency that will remain outstanding. Any reissuance of the Series A Equipment Notes and issuance (or repayment and reissuance) of Additional Series Equipment Notes shall be subject to the terms of Section 9.1(c) and 9.1(d), respectively, of the Intercreditor Agreement; and

(vii) If (x) the Depositary’s long-term issuer credit rating and short-term issuer credit rating by Fitch Ratings, Inc. both fall below the Depositary Threshold Rating (or both such ratings have been withdrawn or suspended), or the Depositary’s short-term unsecured debt rating by Xxxxx’x Investors Service, Inc. falls below the Depositary Threshold Rating (or if such rating has been withdrawn or suspended) or (y) the Company or the Depositary, in its sole discretion, gives written notice to the other of its election that the Depositary be replaced, the Company shall, within 35 days after such event occurring, cause the Depositary to be replaced with a depositary

bank (a “Replacement Depositary”) on the following terms and preconditions:

(A) the Replacement Depositary must meet the Depositary Threshold Ratings and the Company shall have obtained written confirmation from each Rating Agency that such replacement will not cause a withdrawal, suspension or downgrading of any rating then in effect for any Class of Certificates by such Rating Agency (without regard to any withdrawal, suspension or downgrading of any rating of the Depositary being replaced);

(B) the Company shall pay all fees, expenses and other amounts then owing to the replaced Depositary and, except as expressly provided in clause (C) below, the Company shall pay any up-front fee of the Replacement Depositary and (without limitation of the foregoing) all out-of-pocket expenses (including reasonable fees and expenses of legal counsel) of the parties hereto (including without limitation all amounts payable to the Rating Agencies) incurred in connection with such replacement;

(C) solely in the case of the Depositary making an election in its discretion that it be replaced (and without limitation of clause (A) above), (x) the notice given by the Depositary to the Company shall nominate a Replacement Depositary, which shall satisfy all of terms and preconditions of this Section 4(a)(vii) (and the Company shall have the right to utilize such nominee as the Replacement Depositary or to select another Replacement Depositary), (y) the fees, expenses, indemnities and other amounts payable to the Replacement Depositary upon its execution of the Replacement Deposit Agreement or thereafter shall not to any extent exceed those which would have been payable to the Depositary had such replacement not occurred (it being specifically understood and agreed that any up-front fee of the Replacement Depositary shall be paid by the replaced Depositary, provided that, if the Company selects a Replacement Depositary other than the nominee of the replaced Depositary and the upfront fee of such selection exceeds that of such nominee, the Company shall pay such excess), and (without limitation of the foregoing) the Depositary shall pay all out-of-pocket expenses (including reasonable fees and expenses of legal counsel) of the parties hereto (including without limitation all amounts payable to the Rating Agencies) incurred in connection with such replacement, and (z) the Replacement Depositary shall be willing to enter into a Replacement Deposit Agreement for each of the Class AA and Class A Certificates with the Escrow Agent having the same

terms and conditions (including without limitation as to the interest to be paid on the Deposits) as the Deposit Agreements to which the Depositary is a party; and

(D) the Company or, in the case of the Depositary making an election that it be replaced (unless the Company shall have selected such Replacement Depositary), the Depositary, shall cause the Replacement Depositary to enter into a Replacement Deposit Agreement for each of the Class AA and Class A Certificates with the Escrow Agent (and, upon request of the Company the Escrow Agent agrees to enter into any such Replacement Deposit Agreement) and shall cause the Replacement Depositary to deliver to the Company and each Rating Agency legal opinions and other closing documentation substantially similar in scope and substance as those that were delivered by the Depositary being replaced in connection with the execution and delivery of the Deposit Agreement being replaced.

Upon satisfaction of the foregoing conditions, the Company shall instruct the Class AA Pass Through Trustee and the Class A Pass Through Trustee, and each such Pass Through Trustee agrees, to execute and deliver to the Escrow Agent a duly completed Withdrawal Certificate (as defined in the Escrow and Paying Agent Agreements) together with a Notice of Replacement Withdrawal (as defined in the Escrow and Paying Agent Agreements).

Each of the parties hereto agrees, at the Company’s request, to enter into any amendments to this Agreement, the Escrow and Paying Agent Agreements and any other Operative Agreements as may be necessary or desirable to give effect to the replacement of the Depositary with the Replacement Depositary and the replacement of the Deposit Agreements with the Replacement Deposit Agreements.

Upon the execution and delivery of the Replacement Deposit Agreements, the Replacement Depositary shall be deemed to be the Depositary with all of the rights and obligations of the Depositary hereunder and under the other Operative Agreements and the Replacement Deposit Agreements shall be deemed to be the Deposit Agreements hereunder and under the other Operative Agreements, except that the obligations of the replaced Depositary under its Deposit Agreements resulting from the delivery of any Withdrawal Notice delivered thereunder shall remain in full force and effect notwithstanding the execution and delivery of the Replacement Deposit Agreements.

(viii) Promptly after the occurrence of a Triggering Event or an Indenture Default resulting from the failure of the Company to make payments on any Equipment Note and on every Regular Distribution Date while the Triggering Event or such Indenture Default shall be continuing, the Company will, at the Subordination Agent’s request from time to time but in any event no more frequently than once every three months, provide to the Subordination Agent a statement setting forth the following information with respect to each Aircraft then subject to the lien of an Indenture: (A) whether the Aircraft are currently in service or parked in storage, (B) the maintenance status of the Aircraft and (C) the location of the Engines (as defined in the respective Indentures to which such Aircraft are subject). As used in this sentence, the terms “Triggering Event”, “Indenture Default”, “Regular Distribution Date” shall have the respective meanings set forth in the Intercreditor Agreement as originally executed.

(b) WTNA, in its individual capacity, covenants with each of the other parties to this Agreement that it will, immediately upon obtaining knowledge of any facts that would cast doubt upon its continuing status as a “citizen of the United States” as defined in Section 40102(a)(15) of the Act and promptly upon public disclosure of negotiations in respect of any transaction which would or might adversely affect such status, notify in writing all parties hereto of all relevant matters in connection therewith. Upon WTNA giving any such notice, WTNA shall, subject to Section 9.01 of any Indenture then entered into, resign as Loan Trustee in respect of such Indenture.

SECTION 5. Notices. Unless otherwise specifically provided herein, all notices required or permitted by the terms of this Agreement shall be in English and in writing, and any such notice shall become effective upon being delivered personally or, if promptly confirmed by mail, when dispatched by facsimile or other written telecommunication, addressed to such party hereto at its address or facsimile number set forth below the signature of such party at the foot of this Agreement or to such other address or facsimile number as such party may hereafter specify by notice to the other parties.

SECTION 6. Expenses.

PAGE 29

8.1.3

Separate Agreement

This Agreement constitutes a separate agreement with respect to each Indemnitee and is enforceable directly by each such Indemnitee.

8.1.4

Notice

If a claim for any Expense that an Indemnitee shall be indemnified against under this Section 8.1 is made, such Indemnitee shall give prompt written notice thereof to Owner. Notwithstanding the foregoing, the failure of any Indemnitee to notify Owner as provided in this Section 8.1.4, or in Section 8.1.5, shall not release Owner from any of its obligations to indemnify such Indemnitee hereunder, except to the extent that such failure results in an additional Expense to Owner (in which event Owner shall not be responsible for such additional expense) or materially impairs Owner’s ability to contest such claim.

8.1.5

Notice of Proceedings; Defense of Claims; Limitations

(a) In case any action, suit or proceeding shall be brought against any Indemnitee for which Owner is responsible under this Section 8.1, such Indemnitee shall notify Owner of the commencement thereof and Owner may, at its expense, participate in and to the extent that it shall wish (subject to the provisions of the following paragraph), assume and control the defense thereof and, subject to Section 8.1.5(c), settle or compromise the same.

(b) Owner or its insurer(s) shall have the right, at its or their expense, to investigate or, if Owner or its insurer(s) shall agree not to dispute liability to the Indemnitee giving notice of such action, suit or proceeding under this Section 8.1.5 for indemnification hereunder or under any insurance policies pursuant to which coverage is sought, control the defense of, any action, suit or proceeding, relating to any Expense for which indemnification is sought pursuant to this Section 8.1, and each Indemnitee shall cooperate with Owner or its insurer(s) with respect thereto; provided, that Owner shall not be entitled to control the defense of any such action, suit, proceeding or compromise any such Expense during the continuance of any Event of Default. In connection with any

PAGE 30

such action, suit or proceeding being controlled by Owner, such Indemnitee shall have the right to participate therein, at its sole cost and expense, with counsel reasonably satisfactory to Owner; provided, that such Indemnitee’s participation does not, in the reasonable opinion of the independent counsel appointed by the Owner or its insurers to conduct such proceedings, interfere with the defense of such case.

(c) In no event shall any Indemnitee enter into a settlement or other compromise with respect to any Expense without the prior written consent of Owner, which consent shall not be unreasonably withheld or delayed, unless such Indemnitee waives its right to be indemnified with respect to such Expense under this Section 8.1.

(d) In the case of any Expense indemnified by the Owner hereunder which is covered by a policy of insurance maintained by Owner pursuant to Section 4.06 of the Indenture, at Owner’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.

(e) If an Indemnitee is not a party to this Agreement, Owner may require such Indemnitee to agree in writing to the terms of this Section 8 and Section 12.8 prior to making any payment to such Indemnitee under this Section 8.

(f) Nothing contained in this Section 8.1.5 shall be deemed to require an Indemnitee to contest any Expense or to assume responsibility for or control of any judicial proceeding with respect thereto.

8.1.6

Information

Owner will provide the relevant Indemnitee with such information not within the control of such Indemnitee, as is in Owner’s control or is reasonably available to Owner, which such Indemnitee may reasonably request and will otherwise cooperate with such Indemnitee so as to enable such Indemnitee to fulfill its obligations under Section 8.1.5. The Indemnitee shall supply Owner with such information not within the control of Owner, as is in such Indemnitee’s control or is reasonably available to such Indemnitee, which Owner may reasonably request to control or participate in any proceeding to the extent permitted by Section 8.1.5.

PAGE 31

8.1.7

Effect of Other Indemnities; Subrogation; Further Assurances

Upon the payment in full by Owner of any indemnity provided for under this Agreement, Owner, 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 such Indemnitee may have under Section 6.03 or 8.01 of the Trust Indenture) in respect of the matter as to which such indemnity was paid. Each Indemnitee will give such further assurances or agreements and cooperate with Owner to permit Owner to pursue such claims, if any, to the extent reasonably requested by Owner and at Owner’s expense.

8.1.8

Refunds

If an Indemnitee receives any refund, in whole or in part, with respect to any Expense paid by Owner hereunder, it will promptly pay the amount refunded (but not an amount in excess of the amount Owner or any of its insurers has paid in respect of such Expense) over to Owner unless an Event of Default shall have occurred and be continuing, in which case such amounts shall be paid over to Mortgagee to hold as security for Owner’s obligations under the Operative Agreements or, if requested by Owner, applied to satisfy such obligations.

8.2

Expenses

8.2.1

Invoices and Payment

The Mortgagee, the Applicable Pass Through Trustees and the Subordination Agent shall promptly submit to Owner for its prompt approval (which shall not be unreasonably withheld) copies of invoices in reasonable detail of the Transaction Expenses for which it is responsible for providing information as they are received (but in no event later than the 90th day after the Closing Date). If so submitted and approved, the Owner agrees promptly, but in any event no later than the 105th day after the Closing Date, to pay Transaction Expenses.

8.2.2

Payment of Other Expenses

Owner shall pay (i) the ongoing fees and expenses of Mortgagee, and (ii) all reasonable out-of-pocket costs and expenses (including the reasonable fees and disbursements of counsel) incurred by Mortgagee or any Note Holder attributable to any waiver, amendment or modification of any Operative Agreement to the extent requested by Owner.

General Tax Indemnity

8.3.1

General

Except as provided in Section 8.3.2, Owner agrees that each payment paid by Owner under the Equipment Notes, and any other payment or indemnity paid by Owner to a Tax Indemnitee under any Operative Agreement, shall be free of all withholdings or deductions with respect to Taxes of any nature (other than U.S. federal, state or local withholding taxes on, based on or measured by gross or net income, including, without limitation, any such taxes imposed under FATCA), and in the event that Owner shall be required by applicable law to make any such withholding or deduction for any such payment (x) Owner shall make all such withholdings or deductions, (y) the amount payable by Owner shall be increased so that after making all required withholdings or deductions such Tax Indemnitee receives the same amount that it would have received had no such withholdings or deductions been made, and (z) Owner shall pay the full amount withheld or deducted to the relevant Taxing Authority in accordance with applicable law. Except as provided in Section 8.3.2 and whether or not any of the transactions contemplated hereby are consummated, Owner shall pay, indemnify, protect, defend and hold each Tax Indemnitee harmless from all Taxes imposed by any Taxing Authority that may from time to time be 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 but not limited to any Tax imposed upon or with respect to (x) the Aircraft, the Airframe, any Engine, any Part, any Operative Agreement (including without limitation any Equipment Notes) or 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, the imposition of any Lien, financing, refinancing requested by the Owner, abandonment or other disposition of the Aircraft, the Airframe, any Engine, any Part, any data or any

PAGE 33

other thing delivered or to be delivered under an Operative Agreement or (z) interest, fees or any 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.

(m) Taxes relating to ERISA or Section 4975 of the Code.

For purposes hereof, a Tax Indemnitee and any other Tax Indemnitees that are successors, assigns, agents, servants or Affiliates of such Tax Indemnitee shall be related Tax Indemnitees.

PAGE 36

8.3.3

Payment

(a) Owner’s indemnity obligation to a Tax Indemnitee under this Section 8.3 shall equal the amount which, after taking into account any Tax imposed upon the receipt or accrual of the amounts payable under this Section 8.3 and any tax benefits actually recognized by such Tax Indemnitee as a result of the indemnifiable Tax (including, without limitation, any benefits recognized as a result of an indemnifiable Tax being utilized by such Tax Indemnitee as a credit against Taxes not indemnifiable under this Section 8.3), shall equal the amount of the Tax indemnifiable under this Section 8.3.

(b) At Owner’s request, the computation of the amount of any indemnity payment owed by Owner or any amount owed by a Tax Indemnitee to Owner pursuant to this Section 8.3 shall be verified and certified by an independent public accounting firm selected by such Tax Indemnitee and reasonably satisfactory to Owner. Such verification shall be binding. The costs of such verification (including the fee of such public accounting firm) shall be borne by Owner unless such verification shall result in an adjustment in Owner’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.

(c) Each Tax Indemnitee shall provide Owner with such certifications, information and documentation as shall be in such Tax Indemnitee’s possession and as shall be reasonably requested by Owner to minimize any indemnity payment pursuant to this Section 8.3; provided, that notwithstanding anything to the contrary contained herein, no Tax Indemnitee shall be required to provide Owner with any Tax returns.

(d) Each Tax Indemnitee shall promptly forward to Owner any written notice, xxxx or advice received by it from any Taxing Authority concerning any Tax for which it seeks indemnification under this Section 8.3. Owner shall pay any amount for which it is liable pursuant to this Section 8.3 directly to the appropriate Taxing Authority if legally permissible or upon demand of a Tax Indemnitee, to such Tax Indemnitee within 30 days of such demand (or, if a contest occurs in accordance with Section 8.3.4, within 30 days after a Final Determination (as defined below)), but in no event more than one Business Day prior to the date the Tax to which such amount payable hereunder relates is due. If requested by a Tax Indemnitee in writing, Owner shall furnish to the appropriate Tax Indemnitee the original or a certified copy of a receipt for Owner’s payment of any Tax paid by Owner or such other evidence

PAGE 37

of payment of such Tax as is acceptable to such Tax Indemnitee. Owner shall also furnish promptly upon written request such data as any Tax Indemnitee may reasonably require to enable such Tax Indemnitee to comply with the requirements of any taxing jurisdiction unless such data is not reasonably available to Owner or, unless such data is specifically requested by a Taxing Authority, is not customarily furnished by domestic air carriers under similar circumstances. For purposes of this Section 8.3, a “Final Determination” shall mean (i) a decision, judgment, decree or other order by any court of competent jurisdiction that occurs pursuant to the provisions of Section 8.3.4, which decision, judgment, decree or other order has become final and unappealable, (ii) a closing agreement or settlement agreement entered into in accordance with Section 8.3.4 that has become binding and is not subject to further review or appeal (absent fraud, misrepresentation, etc.), or (iii) the termination of administrative proceedings and the expiration of the time for instituting a claim in a court proceeding.

(e) If any Tax Indemnitee shall actually realize a tax savings by reason of any Tax paid or indemnified by Owner pursuant to this Section 8.3 (whether such tax savings shall be by means of a foreign tax credit, depreciation or cost recovery deduction or otherwise) and such savings is not otherwise taken into account in computing such payment or indemnity such Tax Indemnitee shall pay to Owner an amount equal to the lesser of (i) the amount of such tax savings, plus any additional tax savings recognized as the result of any payment made pursuant to this sentence, when, as, if, and to the extent, realized or (ii) the amount of all payments pursuant to this Section 8.3 by Owner to such Tax Indemnitee (less any payments previously made by such Tax Indemnitee to Owner pursuant to this Section 8.3.3(e)) (and the excess, if any, of the amount described in clause (i) over the amount described in clause (ii) shall be carried forward and applied to reduce pro tanto any subsequent obligations of Owner to make payments to such Tax Indemnitee pursuant to this Section 8.3); provided, that such Tax Indemnitee shall not be required to make any payment pursuant to this sentence so long as a Lease Event of Default of a monetary nature has occurred and is continuing. If a tax benefit is later disallowed or denied, the disallowance or denial shall be treated as a Tax indemnifiable under Section 8.3.1 without regard to the provisions of Section 8.3.2 (other than Section 8.3.2(f)). 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.

PAGE 38

8.3.4

Contest

(a) If a written claim is made against a Tax Indemnitee for Taxes with respect to which Owner could be liable for payment or indemnity hereunder, or if a Tax Indemnitee makes a determination that a Tax is due for which Owner could have an indemnity obligation hereunder, such Tax Indemnitee shall promptly give Owner notice in writing of such claim (provided, that failure to so notify Owner shall not relieve Owner of its indemnity obligations hereunder unless such failure to notify effectively forecloses Owner’s rights to require a contest of such claim) and shall take no action with respect to such claim without the prior written consent of Owner for 30 days following the receipt of such notice by Owner; provided, that, in the case of a claim made against a Tax Indemnitee, if such Tax Indemnitee shall be required by law to take action prior to the end of such 30-day period, such Tax Indemnitee shall, in such notice to Owner, so inform Owner, and such Tax Indemnitee shall take no action for as long as it is legally able to do so (it being understood that a Tax Indemnitee shall be entitled to pay the Tax claimed and xxx for a refund prior to the end of such 30-day period if (i)(A) the failure to so pay the Tax would result in substantial penalties (unless immediately reimbursed by Owner) and the act of paying the Tax would not materially prejudice the right to contest or (B) the failure to so pay would result in criminal penalties and (ii) such Tax Indemnitee shall take any action so required in connection with so paying the Tax in a manner that is the least prejudicial to the pursuit of the contest). In addition, such Tax Indemnitee shall (provided, that Owner shall have agreed to keep such information confidential other than to the extent necessary in order to contest the claim) furnish Owner with copies of any requests for information from any Taxing Authority relating to such Taxes with respect to which Owner may be required to indemnify hereunder. If requested by Owner in writing within 30 days after its receipt of such notice, such Tax Indemnitee shall, at the expense of Owner (including, without limitation, all reasonable costs, expenses and reasonable attorneys’ and accountants’ fees and disbursements), in good faith contest (or, if permitted by applicable law, allow Owner to contest) through appropriate administrative and judicial proceedings the validity, applicability or amount of such Taxes by (I) resisting payment thereof, (II) not paying the same except under protest if protest is necessary and proper or (III) if the payment is made, using reasonable efforts to obtain a refund thereof in an appropriate administrative and/or judicial proceeding. If requested to do so by Owner, the Tax Indemnitee shall appeal any

PAGE 39

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 the Tax Indemnitee is able to separate the contested issue or issues from other issues arising in the same administrative or judicial proceeding that are unrelated to the transactions contemplated by the Operative Agreements without, in the good faith judgment of such Tax Indemnitee, adversely affecting such Tax Indemnitee, such Tax Indemnitee shall permit Owner to control the conduct of any such proceeding and shall provide to Owner (at Owner’s cost and expense) with such information or data that is in such Tax Indemnitee’s control or possession that is reasonably necessary to conduct such contest. In the case of a contest controlled by a Tax Indemnitee, such Tax Indemnitee shall consult with Owner in good faith regarding the manner of contesting such claim and shall keep Owner reasonably informed regarding the progress of such contest. A Tax Indemnitee shall not fail to take any action expressly required by this Section 8.3.4 (including, without limitation, any action regarding any appeal of an adverse determination with respect to any claim) or settle or compromise any claim without the prior written consent of the Owner (except as contemplated by Section 8.3.4(b) or (c)).

(b) Notwithstanding the foregoing, in no event shall a Tax Indemnitee be required to pursue any contest (or to permit Owner to pursue any contest) unless (i) Owner shall have agreed to pay such Tax Indemnitee on demand all reasonable costs and expenses incurred by such Tax Indemnitee in connection with contesting such Taxes, including, without limitation, all reasonable out of pocket costs and expenses and reasonable attorneys’ and accountants’ fees and disbursements, (ii) if such contest shall involve the payment of the claim, Owner shall advance the amount thereof (to the extent indemnified hereunder) plus interest, penalties and additions to tax with respect thereto that are required to be paid prior to the commencement of such contest on an interest-free after-Tax basis to such Tax Indemnitee (and such Tax Indemnitee shall promptly pay to the Owner any net realized tax benefits resulting from such advance including any tax benefits resulting from making such payment), (iii) such Tax Indemnitee shall have reasonably determined that the action to be taken will not result in any material risk of forfeiture, sale or loss of the Aircraft (unless Owner shall have made provisions to protect the interests of any such Tax Indemnitee in a manner reasonably satisfactory to such Tax Indemnitee) (provided, that such Tax Indemnitee agrees to notify Owner in writing promptly after it becomes aware of any such risk), (iv) no Lease Event of Default shall have occurred and be

PAGE 40

continuing unless Owner has provided security for its obligations hereunder by advancing 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 (v) prior to commencing any judicial action controlled by Owner, Owner shall have acknowledged its liability for such claim hereunder, provided that Owner shall not be bound by its acknowledgment if the Final Determination articulates conclusions of law and fact that demonstrate that Owner has no liability for the contested amounts hereunder. Notwithstanding the foregoing, if any Tax Indemnitee shall release, waive, compromise or settle any claim which may be indemnifiable by Owner pursuant to this Section 8.3 without the written permission of Owner, Owner’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, subject to Section 8.3.4(c), and subject to Section 8.3.4(c), such Tax Indemnitee shall repay to Owner any amount previously paid or advanced to such Tax Indemnitee with respect to such claim, plus interest at the rate that would have been payable by the relevant Taxing Authority with respect to a refund of such Tax.

(c) Notwithstanding anything contained in this Section 8.3, 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 Owner’s consent if such Tax Indemnitee (i) shall waive its right to indemnity under this Section 8.3 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), (ii) shall pay to Owner any amount previously paid or advanced by Owner pursuant to this Section 8.3 with respect to such Tax, plus interest at the rate that would have been payable by the relevant Taxing Authority with respect to a refund of such Tax, and (iii) shall agree to discuss with Owner the views or positions of any relevant Taxing Authority with respect to the imposition of such Tax.

8.3.5

Refund

If any Tax Indemnitee shall receive a refund of, or be entitled to a credit against other liability for, all or any part of any Taxes paid, reimbursed or advanced by Owner, such Tax Indemnitee shall pay to Owner 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

PAGE 41

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 Owner to such Tax Indemnitee theretofore made pursuant to this Section 8.3 (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 Owner to make payments to such Tax Indemnitee pursuant to this Section 8.3). If, in addition to such refund or credit, such Tax Indemnitee shall receive (or be credited with) an amount representing interest on the amount of such refund or credit, such Tax Indemnitee shall pay to Owner within 30 days of such receipt or realization of such credit that proportion of such interest that shall be fairly attributable to Taxes paid, reimbursed or advanced by Owner prior to the receipt of such refund or realization of such credit.

8.3.6

Tax Filing

If any report, return or statement is required to be filed with respect to any Tax which is subject to indemnification under this Section 8.3, Owner shall timely file the same (except for any such report, return or statement which a Tax Indemnitee has timely notified the Owner 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 Owner with any information in such Tax Indemnitee’s possession or control that is reasonably necessary to file any such return, report or statement and is reasonably requested in writing by Owner (it being understood that the Tax Indemnitee shall not be required to furnish copies of its actual tax returns, although it may be required to furnish relevant information contained therein). Owner shall either file such report, return or statement and send a copy of such report, return or statement to such Tax Indemnitee, or, where Owner 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 satisfactory to such Tax Indemnitee within a reasonable time prior to the time such report, return or statement is to be filed.

8.3.7

Forms

Each Tax Indemnitee agrees to furnish from time to time to Owner or Mortgagee or to such other person as Owner or

Mortgagee may designate, at Owner’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 (x) such reduction or exemption is available to such Tax Indemnitee and (y) Owner has provided such Tax Indemnitee with any information necessary to complete such form not otherwise reasonably available to such Tax Indemnitee.

8.3.8

Non-Parties

If a Tax Indemnitee is not a party to this Agreement, Owner may require the Tax Indemnitee to agree in writing, in a form reasonably acceptable to Owner, to the terms of this Section 8.3 and Section 15.8 prior to making any payment to such Tax Indemnitee under this Section 8.3.

8.3.9

Subrogation

Upon payment of any Tax by Owner pursuant to this Section 8.3 to or on behalf of a Tax Indemnitee, Owner, without any further action, shall be subrogated to any claims that such Tax Indemnitee may have relating thereto. Such Tax Indemnitee shall cooperate with Owner (to the extent such cooperation does not result in any unreimbursed cost, expense or liability to such Tax Indemnitee) to permit Owner to pursue such claims.

8.4

Payments

Any payments made pursuant to Section 8.1 or 8.3 shall be due on the 60th day after demand therefor and shall be made directly to the relevant Indemnitee or Tax Indemnitee or to Owner, in immediately available funds at such bank or to such account as specified by such Indemnitee or Tax Indemnitee or Owner, as the case may be, in written directives to the payor, or, if no such direction shall have been given, by check of the payor payable to the order of, and mailed to, such Indemnitee or Tax Indemnitee or Owner, as the case may be, by certified mail, postage prepaid, at its address as set forth in this Agreement.

8.5

Interest

If any amount, payable by Owner, any Indemnitee or any Tax Indemnitee under Section 8.1 or 8.3 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 same

PAGE 43

is paid, at the Payment Due Rate. Such interest shall be paid in the same manner as the unpaid amount in respect of which such interest is due.

8.6

Benefit of Indemnities

The obligations of Owner in respect of all indemnities, obligations, adjustments and payments in Section 8.1 or 8.3 are expressly made for the benefit of, and shall be enforceable by, the Indemnitee or Tax Indemnitee entitled thereto, notwithstanding any provision of the Trust Indenture.

SECTION 9.

ASSIGNMENT OR TRANSFER OF INTEREST

9.1

Note Holders

Subject to Section 6.3.2 hereof and Section 2.07 of the Trust Indenture, any Note Holder may, at any time and from time to time, Transfer or grant participations in all or any portion of the Equipment Notes and/or all or any portion of its beneficial interest in its Equipment Notes to any person (it being understood that the sale or issuance of Pass Through Certificates by a Pass Through Trustee shall not be considered a Transfer or participation); provided, that any participant in any such participations shall not have any direct rights under the Operative Agreements or any Lien on all or any part of the Aircraft or the Collateral and Owner shall not have any increased liability or obligations as a result of any such participation. In the case of any such Transfer, the Transferee, by acceptance of Equipment Notes in connection with such Transfer, shall be deemed to be bound by (i) all of the covenants of Note Holders contained in the Operative Agreements and (ii) certain terms of the Intercreditor Agreement as specified in such Equipment Notes and/or Section 2.07 of the Trust Indenture.

9.2

Effect of Transfer

Upon any Transfer in accordance with Section 9.1 (other than any Transfer by any Note Holder, to the extent it only grants participations in Equipment Notes or in its beneficial interest therein), Transferee shall be deemed a “Note Holder,” for all purposes of this Agreement and the other Operative Agreements, and the transferring Note Holder shall be released from all of its liabilities and obligations under this Agreement and any other Operative Agreements to the extent such liabilities and obligations arise after such Transfer and, in

PAGE 44

each case, to the extent such liabilities and obligations are assumed by the Transferee; provided, that such transferring Note Holder (and its respective Affiliates, successors, assigns, agents, servants, representatives, directors and officers) will continue to have the benefit of any rights or indemnities under any Operative Agreement vested or relating to circumstances, conditions, acts or events prior to such Transfer.

SECTION 10.

SECTION 1110

It is the intention of each of the Owner, the Note Holders (such intention being evidenced by each of their acceptance of an Equipment Note), and Mortgagee that Mortgagee shall be entitled to the benefits of Section 1110 in the event of a case under Chapter 11 of the Bankruptcy Code in which Owner is a debtor.

SECTION 11.

CHANGE OF CITIZENSHIP

11.1

Generally

Without prejudice to the representations, warranties or covenants regarding the status of any party hereto as a Citizen of the United States, each of Owner, WTNA and Mortgagee agrees that it will, immediately upon obtaining knowledge of any facts that would cast doubt upon its continuing status as a Citizen of the United States and promptly upon public disclosure of negotiations in respect of any transaction which would or might adversely affect such status, notify in writing all parties hereto of all relevant matters in connection therewith.

11.2

Mortgagee

Upon WTNA giving any notice in accordance with Section 11.1, Mortgagee shall (if and so long as such citizenship is necessary under the Act as in effect at such time or, if it is not necessary, if and so long as Mortgagee’s citizenship could have any adverse effect on Owner, or any Note Holder), subject to Section 9.02 of the Trust Indenture, resign as Mortgagee promptly upon its ceasing to be such a citizen.

SECTION 12.

MISCELLANEOUS

No provision of this Agreement may be amended, supplemented, waived, modified, discharged, terminated or otherwise varied orally, but only by an instrument in writing

PAGE 45

that specifically identifies the provision of this Agreement that it purports to amend, supplement, waive, modify, discharge, terminate or otherwise vary and is signed by the party against which the enforcement of the amendment, supplement, waiver, modification, discharge, termination or variance is sought. Each such amendment, supplement, waiver, modification, discharge, termination or variance shall be effective only in the specific instance and for the specific purpose for which it is given. No provision of this Agreement shall be varied or contradicted by oral communication, course of dealing or performance or other manner not set forth in an agreement, document or instrument in writing and signed by the party against which enforcement of the same is sought.

12.2

Severability

If any provision hereof shall be held invalid, illegal or unenforceable in any respect in any jurisdiction, then, to the extent permitted by Law, (a) all other provisions hereof shall remain in full force and effect in such jurisdiction and (b) such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such provision in any other jurisdiction. If, however, any Law pursuant to which such provisions are held invalid, illegal or unenforceable may be waived, such Law is hereby waived by the parties hereto to the full extent permitted, to the end that this Agreement shall be deemed to be a valid and binding agreement in all respects, enforceable in accordance with its terms.

12.6

No Waiver

No failure on the part of any party hereto to exercise, and no delay by any party hereto in exercising, any of its respective rights, powers, remedies or privileges under this Agreement or provided at Law, in equity or otherwise shall impair, prejudice or constitute a waiver of any such right, power, remedy or privilege or be construed as a waiver of any breach hereof or default hereunder or as an acquiescence therein nor shall any single or partial exercise of any such right, power, remedy or privilege preclude any other or further exercise thereof by it or the exercise of any other right, power, remedy or privilege by it. No notice to or demand on any party hereto in any case shall, unless otherwise required under this Agreement, entitle such party to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of any party hereto to any other or further action in any circumstances without notice or demand.

12.7

EXHIBIT A

PARTICIPATION AGREEMENT

[Form of Opinion of Owner’s Special Counsel]

[DATE]

To the Persons Listed on Schedule I

Attached Hereto

Re:

Mortgage of Boeing Model [MOD] Aircraft with

Manufacturer’s Serial Number [MSN] and U.S. Registration

Number N[REG]

Ladies and Gentlemen:

We have been requested by United Airlines, Inc., a Delaware corporation (the “Company”), to act as special counsel with respect to, and to render this opinion letter in connection with, the transactions contemplated by the Participation Agreement [TN], dated as of [DD] (the “Participation Agreement”), among the Company, as Owner, and Wilmington Trust, National Association, a national banking association (“WTNA”), in its capacity as Mortgagee (the “Mortgagee”), as Subordination Agent under the Intercreditor Agreement and as Pass Through Trustee under the Applicable Pass Through Trust Agreements. Capitalized terms used herein and not otherwise defined herein have the respective meanings given to those terms pursuant to the Participation Agreement.

In connection with this opinion letter we have examined, among other things, originals or copies certified or otherwise identified to our satisfaction of the following documents:

(i)

Participation Agreement;

(ii)

Trust Indenture;

(iii)

Trust Indenture Supplement No. 1;

(iv)

Forms of the Equipment Notes;

(v)

Consent and Agreement;

(vi)

Engine Consent and Agreement; and

(vii)

Bills of Sale.

We have also examined and relied upon such other documents and such other corporate records, certificates and other statements of governmental officials and corporate officers and other representatives of the Company as we have deemed necessary or appropriate for the purposes of this opinion. As to certain facts material to the opinions expressed herein, we have relied upon representations and warranties contained in the Operative Agreements. The opinions expressed herein are subject to the following exceptions, assumptions, qualifications and limitations:

A. The opinions set forth below are limited to the laws of the State of New York, the federal laws of the United States of America and the General Corporation Law of the State of Delaware, except that we express no opinion with respect to (i) the laws, regulations or ordinances of any county, town or municipality or governmental subdivision or agency thereof, (ii) state securities or blue sky laws or federal securities laws, including the Securities Act and the Investment Company Act of 1940, as amended, (iii) any federal or state tax, antitrust or fraudulent transfer or conveyance laws, (iv) the Employee Retirement Income Security Act of 1974, as amended, or (v) the Act (except as expressly provided in paragraph 5 below), the Cape Town Treaty or any other laws, rules or regulations governing, regulating or relating to the acquisition, ownership, registration, use or sale of an aircraft, airframe or aircraft engine or to the particular nature of the equipment to be acquired by the Company. In addition, our opinions are based upon a review of those laws, statutes, rules and regulations which, in our experience, are normally applicable to transactions of the type contemplated by the Participation Agreement.

B. The opinions set forth in paragraph 3 below are subject to (i) limitations on enforceability arising from applicable bankruptcy, insolvency, reorganization, moratorium, receivership, fraudulent conveyance, fraudulent transfer, preferential transfer and similar laws relating to or affecting the rights and remedies of creditors generally and the effect of general principles of equity, including, without limitation, laches and estoppel as equitable defenses and concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether such enforceability is considered or applied in a proceeding in equity or at law) and considerations of impracticability or impossibility of performance, and defenses based upon unconscionability of otherwise enforceable obligations in the context of the factual circumstances under which enforcement thereof is sought and (ii) the qualification that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceeding therefor may be brought. In addition, certain remedial and procedural provisions of the Company Documents (as defined in paragraph 2 below) are or may be unenforceable in whole or in part, but the inclusion of such provisions does not affect the validity of those agreements and does not, in our opinion, make the remedies provided in those agreements, or otherwise available under applicable law, inadequate for the practical realization of the substantive benefits purported to be provided thereby, except for the economic consequences resulting from any delay imposed by, or any procedure required by, applicable laws, rules, regulations and by constitutional requirements. We express no opinion as to (i) any provision contained in any Operative Agreement (a) providing for indemnification or exculpation of any Person for such Person’s gross negligence, willful misconduct, recklessness or unlawful conduct or in respect of liabilities under the Securities Act, (b) providing for a premium, late payment charges or an increase in interest rate upon delinquency in payment or the

occurrence of a default or other specified event but only to the extent such provision is deemed to constitute a penalty or liquidated damages provision, (c) as such provision relates to the subject matter jurisdiction of federal courts or the waiver of inconvenient forum with respect to proceedings in federal courts, (d) that purports to establish (or may be construed to establish) evidentiary standards, (e) providing for the waiver of any statutory right or any broadly or vaguely stated rights or unknown future rights, or any waiver which is against public policy considerations or (f) providing for severability of the provisions of an Operative Agreement or (ii) Section 12.8(e) of the Participation Agreement or any comparable provision of any other Operative Agreement. Under certain circumstances the requirement that the provisions of an Operative Agreement may be modified or waived only in writing or only in a specific instance and provisions to the effect that failure or delay in exercising any right, remedy, power and/or privilege will not impair or waive such right, remedy, power and/or privilege may be unenforceable to the extent that an oral agreement has been effected or a course of dealing has occurred modifying such provisions. A court may modify or limit contractual agreements regarding attorneys’ fees.

C. To the extent that our opinions expressed herein involve conclusions as to the matters set forth in the opinions dated the date hereof of the United Airlines, Inc. Legal Department, Xxxxxx Xxxxx LLP or Xxxxx, Xxxxx & Xxxxxx being delivered to you on the date hereof, we have assumed, without independent investigation, the correctness of the matters set forth in such opinions.

D. We have assumed the due authorization, execution and delivery of the Operative Agreements by each of the parties thereto, that each of such parties (other than the Company) has the power and authority to execute, deliver and perform each such Operative Agreement and has obtained or made all necessary consents, approvals, filings and registrations in connection therewith (except any required under New York law by the Company), that such execution, delivery and performance does not violate its charter, by-laws or similar instrument, that value has been given by each Applicable Pass Through Trustee to the Company under the Trust Indenture, that the Company has rights in the Collateral and that WTNA is duly organized, validly existing and in good standing in its jurisdiction of organization and qualified to transact business in each other jurisdiction where such qualification is required.

E. We have assumed the due authentication of the Equipment Notes by the Mortgagee and the delivery thereof against payment therefor, all in accordance with the Participation Agreement and the Trust Indenture, and that the Equipment Notes conform to the forms thereof examined by us. We have assumed that the Company holds an air carrier operating certificate issued pursuant to Chapter 447 of Title 49 of the United States Code for aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of cargo.

F. We have assumed that all signatures on documents examined by us are genuine, that all persons signing such documents have legal capacity, that all documents submitted to us as originals are authentic and that all documents submitted to us as copies or specimens conform with the originals, which facts we have not independently verified.

G. We express no opinion as to any provision in any Operative Agreement that is contrary to Sections 9-401, 9-406, 9-407 or 9-408 or Part VI of Article 9, of the UCC.

H. We have not made any examination of, and express no opinion with respect to (and to the extent relevant have assumed the accuracy and sufficiency of), (i) descriptions of, the legal or beneficial ownership of, or the title or condition of title to, the Collateral or any other property covered by any of the Operative Agreements, (ii) except as expressly set forth in paragraphs 5 and 7 below, the existence, creation, validity or attachment of any Lien thereon, (iii) except as expressly set forth in paragraph 5 below, the perfection of any Lien thereon and (iv) the priority or enforcement of any Lien thereon.

I. In giving an opinion regarding the valid existence and good standing of the Company, we have relied solely upon certificates of public officials.

J. The opinions expressed herein are given as of the date hereof. We assume no obligation to advise you of any facts or circumstance that may come to our attention, or any changes in law that may occur after the date hereof, which may affect the opinion expressed herein.

Based on and subject to the foregoing, we are of the opinion that:

1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware.

2. The Company has all necessary corporate power to execute, deliver and perform its obligations under the Participation Agreement, the Trust Indenture, the Trust Indenture Supplement No. 1 and the Equipment Notes (collectively, the “Company Documents”). Neither the execution nor delivery of the Company Documents by the Company nor the consummation of the transactions contemplated thereby will result in any violation of (a) its Amended and Restated Certificate of Incorporation or Amended and Restated By-laws or (b) any law, governmental rule or regulation known to us to be applicable to, or binding on, the Company, or requires the approval of the stockholders of the Company.

3. Each Company Document constitutes the valid and binding obligation of the Company and is enforceable against the Company in accordance with its terms.

4. Except for the matters referred to in clauses (i) through (iv) of paragraph 5 below, no approval, authorization or other action by or filing with any governmental authority is required for the execution and delivery by the Company of the Company Documents or the consummation of the transactions contemplated thereby to occur at the Closing.

5. Except for (i) the filing and recordation in accordance with the Act of the Trust Indenture, Trust Indenture Supplement No. 1 and the FAA Xxxx of Sale, and assuming that at the time of such filing no other unrecorded document relating to the Aircraft has been filed pursuant to the Act, (ii) the filing with the FAA pursuant to the FAA Regulations of the Forms 8050-135 referred to in Section 5.1.6 of the Participation Agreement, (iii) the filing of Financing

Statements referred to in Section 4.1.11 of the Participation Agreement (and the filing of periodic continuation statements with respect thereto) and (iv) the filing of an FAA Application for Registration (on AC Form 8050-1 or other form as may be approved by the FAA) relating to the Aircraft in the name of the Company and the registration of the Aircraft in the name of the Company with the FAA pursuant to the Act (and the periodic renewal of such registration with the FAA prior to its expiration), (a) no further filing or recording of any document is necessary (x) to establish the Company’s title to the Airframe and Engines, and (y) to create a valid security interest in the Company’s interest as owner of the Airframe and Engines or in the Purchase Agreement (to the extent a security interest therein is created by the Trust Indenture) in favor of the Mortgagee pursuant to the Trust Indenture and (b) no further filing or recording of any document in the State of New York or under the Act is required to perfect a security interest in the Company’s interest as owner of the Airframe and Engines or in the Purchase Agreement (to the extent a security interest therein is created by the Trust Indenture) in favor of the Mortgagee pursuant to the Trust Indenture.

6. The Mortgagee will be entitled to the benefits of Section 1110 of Title 11 of the United States Code with respect to the Airframe and Engines delivered on the date hereof in connection with any case commenced by or against the Company under Chapter 11 of Title 11 of the United States Code.

7. Upon issuance, execution, authentication and delivery of the Equipment Notes at the Closing, the Trust Indenture creates the security interest in favor of the Mortgagee, as trustee for the benefit of the holders of the Equipment Notes, in the Collateral it purports to create to the extent that the UCC applies to a security interest in such property.

This opinion is being delivered pursuant to Section 4.1.2(x)(A) of the Participation Agreement. This opinion may be relied upon by you (and any permitted Transferee under Section 9.1 of the Participation Agreement) in connection with the matters set forth herein and, without our prior written consent, may not be relied upon for any other purpose and may not be relied upon by any other Person for any purpose.

Very truly yours,

Ladies and Gentlemen:

This opinion letter is being delivered by United Airlines, Inc., a Delaware corporation (“United”), through its Legal Department in connection with the transactions contemplated by the Participation Agreement [TN] dated as of [DD], among Wilmington Trust, National Association, a national banking association, as Mortgagee, Subordination Agent under the Intercreditor Agreement and as Pass Through Trustee under the Applicable Pass Through Trust Agreements, and United, as Owner (the “Participation Agreement”). All capitalized terms used herein and not otherwise defined herein shall have the respective meanings given those terms pursuant to the Participation Agreement. This opinion letter is being furnished to you pursuant to Section 4.1.2(x)(B) of the Participation Agreement.

In giving the following opinions, members of United’s Legal Department or lawyers retained by United’s Legal Department have reviewed the Participation Agreement and the other Operative Agreements to which United is a party and have relied upon originals, or copies certified or otherwise identified to our satisfaction, of such records, documents, certificates and other instruments as in our judgment are necessary or appropriate to enable us to render the opinions expressed below. In addition, United’s Legal Department has assumed and has not verified the accuracy as to factual matters of each document reviewed. As used herein, the phrase “to our knowledge” or words of similar import shall mean to the actual knowledge of members of United’s Legal Department after reasonable investigation, but shall not be interpreted to impute to any member of United’s Legal Department knowledge of others.

Based on the foregoing, and subject to the assumptions and limitations contained herein, United’s Legal Department is of the opinion that:

(a) United is an “air carrier” within the meaning of Section 40102 of the Act, holds an air carrier operating certificate issued pursuant to Chapter 447 of Title 49 of the United States Code for aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of cargo, is a “citizen of the United States” as such term is defined in Section 40102 of such Act and holds all authority, necessary licenses and certificates under such Act and the rules and regulations promulgated thereunder necessary for the conduct of its business and to perform its obligations under the Participation Agreement, the Trust Indenture, the Trust Indenture Supplement No. 1 and the Equipment Notes (collectively, the “Agreements”).

(b) The execution, delivery and performance by United of each of the Agreements do not, to our knowledge, constitute a breach or result in a default under any indenture, mortgage, deed of trust, credit agreement, conditional sale contract or other loan agreement to which United is a party or by which United or its property may be bound.

(c) The execution, delivery and performance of each of the Agreements has been duly authorized by all necessary corporate action on the part of United, and each of the Agreements has been duly executed and delivered by United.

(d) There are no pending or, to our knowledge, threatened actions, suits or proceedings before any court or administrative agency or arbitrator that question the validity of any of the Agreements or that would have been required to be disclosed in United’s Annual Report on Form 10-K filed for the year ended December 31, [___], or any subsequent Quarterly Report on Form 10-Q or Current Report on Form 8-K (or amendment to any of the foregoing), except such as are therein disclosed.

The foregoing opinions are limited to the federal law of the United States of America (other than (i) the Act (except as expressly provided in paragraph (a) above), the Cape Town Treaty or any other laws, rules or regulations governing, regulating or relating to the acquisition, ownership, registration, use or sale of an aircraft, airframe or aircraft engine or to the particular nature of the equipment to be acquired by United, (ii) federal securities laws, (iii) federal tax, antitrust or fraudulent transfer or conveyance laws, as to which we express no opinion), the General Corporation Law of the State of Delaware and the law of the State of Illinois (other than state securities or blue sky laws, or state tax, antitrust or fraudulent transfer or conveyance laws, as to which we express no opinion).

This opinion letter can be relied upon only by you for the purpose indicated above, and may not be relied upon by any other Person (except any permitted Transferee under Section 9.1 of the Participation Agreement) or for any other purpose without our written consent.

Re:

United Airlines, Inc. - Financing of One Boeing Model [ - ] Aircraft

Bearing Manufacturer’s Serial Number [ ]

Ladies and Gentlemen:

We have acted as counsel to Wilmington Trust, National Association (“WTNA”), in connection with the Trust Indenture and Mortgage [ ], dated as of [ , ] (the “Trust Indenture”), between WTNA, as mortgagee (the “Mortgagee”), and United Airlines, Inc. (the “Owner”). Pursuant to Participation Agreement [ ], dated as of [ , ] (the “Participation Agreement”), among the Owner and WTNA, as Mortgagee, Paying Agent, Subordination Agent under the Intercreditor Agreement (as defined in the Participation Agreement) and as Pass Through Trustee (as defined in the Participation Agreement), financing is being provided for one Boeing Model [ - ] aircraft bearing manufacturer’s serial number [ ]. This opinion is furnished pursuant to Section 4.1.2 (x)(C) of the Participation Agreement. Capitalized terms used herein and not otherwise defined are used as defined in the Trust Indenture, except that reference herein to any document shall mean such document as in effect on the date hereof.

We have examined originals or copies of the following documents:

(a) The Trust Indenture and the initial Trust Indenture Supplement;

(b) The Participation Agreement (the documents referred to in paragraphs (a) and (b) above being collectively referred to as the “Transaction Documents”); and

We have also examined originals or copies of such other documents and such corporate records, certificates and other statements of governmental officials and corporate officers and other representatives of the corporations or entities referred to herein as we have deemed necessary or appropriate for the purposes of this opinion. Moreover, as to certain facts material to the opinions expressed herein, we have relied upon representations and warranties contained in the documents referred to in this paragraph.

To Each of the Parties Listed

on Schedule A Hereto

Page 2

Based upon the foregoing and upon an examination of such questions of law as we have considered necessary or appropriate, and subject to the assumptions, exceptions and qualifications set forth below, we advise you that, in our opinion:

1. WTNA has been duly incorporated and is validly existing in good standing as a national banking association under the laws of the United States of America, is a “citizen of the United States” within the meaning of Section 40102(a)(15) of Title 49 of the United States Code, as amended, and has full power, authority and legal right to execute, deliver and perform its obligations under the Transaction Documents and to authenticate the Equipment Notes.

2. The Mortgagee, the Subordination Agent, the Paying Agent, the Pass Through Trustee or WTNA, as the case may be, has duly authorized, executed and delivered each Transaction Document to which it is party, and each Equipment Note, and each such document constitutes a legal, valid and binding obligation of the Mortgagee, the Subordination Agent, the Paying Agent, the Pass Through Trustee or WTNA, as the case may be, enforceable against the Mortgagee, the Subordination Agent, the Paying Agent, the Pass Through Trustee or WTNA, as the case may be, in accordance with its terms.

3. The execution, delivery and performance by the Mortgagee, the Subordination Agent, the Paying Agent, the Pass Through Trustee or WTNA, as the case may be, of the Transaction Documents to which it is a party, the authentication by the Mortgagee of the Equipment Notes and the consummation by the Mortgagee, the Subordination Agent, the Paying Agent, the Pass Through Trustee or WTNA, as the case may be, of any of the transactions contemplated thereby are not in violation of the charter or by-laws of WTNA or of any law, governmental rule or regulation of the State of Delaware or the United States governing the trust powers of WTNA or, to our knowledge, any indenture, mortgage, bank credit agreement, note or bond purchase agreement, long-term lease, license or other agreement or instrument to which WTNA is a party or by which it is bound or, to our knowledge, any judgment or order applicable to WTNA.

4. None of the execution and delivery by the Mortgagee, the Subordination Agent, the Paying Agent, the Pass Through Trustee or WTNA, as the case may be, of the Transaction Documents to which it is a party, the authentication of the Equipment Notes or the consummation of any of the transactions by the Mortgagee, the Subordination Agent, the Paying Agent, the Pass Through Trustee or WTNA, as the case may be, contemplated thereby, requires the consent or approval of, the giving of notice to, the registration with, or the taking of any other action in respect of, any governmental authority or agency of the State of Delaware or the United States governing the trust powers of WTNA or under any Delaware law.

To Each of the Parties Listed

on Schedule A Hereto

Page 3

5. No taxes, fees or other charges (other than taxes payable by WTNA on or measured by any compensation received by WTNA for its services as Mortgagee, Subordination Agent or Pass Through Trustee) are required to be paid by the Subordination Agent, the Paying Agent, the Pass Through Trustee or the Mortgagee or the trust created by the Trust Indenture under the laws of the State of Delaware, or any political subdivision thereof, in connection with the execution, delivery or performance of the Transaction Documents to which the Mortgagee, the Subordination Agent or the Pass Through Trustee is party and the Equipment Notes, which taxes, fees or other charges would not be required to be paid if WTNA were not a national banking association and did not perform its obligations as Mortgagee under the Trust Indenture in the State of Delaware.

6. The Equipment Notes have been duly and validly authenticated by the Mortgagee in accordance with the Trust Indenture.

7. To our knowledge, there are no proceedings pending or threatened against or affecting the Mortgagee, the Subordination Agent, the Paying Agent, the Pass Through Trustee or WTNA in any court or before any governmental authority, agency, arbitration board or tribunal which, if adversely determined, individually or in the aggregate, would materially and adversely affect the Mortgaged Property or the right, power and authority of the Mortgagee, the Subordination Agent, the Paying Agent, the Pass Through Trustee or WTNA, as the case may be, to enter into or perform its obligations under the Transaction Documents to which it is party.

The foregoing opinions are subject to the following assumptions, exceptions and qualifications:

A. We are admitted to practice law in the State of Delaware and we do not hold ourselves out as being experts on the law of any other jurisdiction. The foregoing opinions are limited to the laws of the State of Delaware (and its political subdivisions to the extent set forth in paragraph 5 above), the federal laws of the United States of America governing the banking and trust powers of WTNA, except that we express no opinion with respect to (i) federal securities laws, including the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, the Investment Company Act of 1940, as amended, and the Trust Indenture Act of 1939, as amended, (ii) Part A of Subtitle VII of Title 49 of the United States Code, as amended (except with respect to the opinion set forth in paragraph 1 above concerning the citizenship of WTNA), (iii) the Federal Communications Act of 1934, as amended, (iv) state securities or blue sky laws, or (v) laws, rules and regulations applicable to the particular nature of the equipment acquired by the Company. Insofar as the foregoing opinions relate to the validity and enforceability of the Transaction Documents expressed to be governed by the laws of the State of New York, we have assumed that each such document is legal, valid, binding and enforceable in accordance with its terms under such laws (as to which we express no opinion).

B. The foregoing opinions regarding enforceability are subject to (i) applicable bankruptcy, insolvency, moratorium, reorganization, receivership, fraudulent conveyance and similar laws relating to or affecting the enforcement of the rights and remedies of creditors generally, and (ii) principles of equity (regardless of whether considered and applied in a proceeding in equity or at law).

To Each of the Parties Listed

on Schedule A Hereto

C. We have assumed that each of the parties to the Transaction Documents and the Equipment Notes (except the Mortgagee, the Subordination Agent, the Paying Agent, the Pass Through Trustee or WTNA, as the case may be) has full power, authority and legal right to execute, deliver and perform each such document and that each such document has been duly authorized, executed and delivered by each such party.

D. We have assumed that all signatures (other than signatures of officers of WTNA) on documents examined by us are genuine, that all documents submitted to us as originals are authentic and that all documents submitted to us as copies conform with the originals, which facts we have not independently verified.

E. We have assumed that the Participation Agreement and the transactions contemplated thereby are not within the prohibitions of Section 406 of the Employee Retirement Income Security Act of 1974, as amended.

F. No opinion is expressed as to the creation, attachment, perfection or priority of any mortgage or security interests or as to the nature or validity of title to any part of the Mortgaged Property.

G. The opinion set forth in paragraph (1) above concerning the citizenship of WTNA is based upon an affidavit of WTNA, made by one of its Vice Presidents, the facts set forth in which we have not independently verified.

H. In basing the opinions set forth herein on “our knowledge,” the words “our knowledge” signify that no information has come to the attention of the attorneys in the firm who are directly involved in the representation of WTNA in this transaction that would give us actual knowledge that any such opinions are not accurate. Except as otherwise stated herein, we have undertaken no independent investigation or verification of such matters.

This opinion may be relied upon by you in connection with the matters set forth herein. This opinion may also be relied upon by any transferee of a Note Holder subject to the understanding that the opinions expressed herein are rendered as of the date hereof and only with respect to the laws, rules and regulations in effect as of such date. Otherwise, without our prior written consent, this opinion may not be relied upon by any other person or entity for any purpose.

FORM OF OPINION

Re: Boeing model (described as model on the International

Registry) aircraft with manufacturer’s serial number and United

States nationality and registration marks N (the “Aircraft”)

To the Addressees Listed on

the Attached Exhibit A

Ladies and Gentlemen:

Acting as special legal counsel in connection with the transactions contemplated by the instruments described below, this opinion is furnished to you with respect to: (i) registering interests with the International Registry (the “International Registry”) created pursuant to and in accordance with the provisions of the Convention on International Interests in Mobile Equipment, the Protocol to the Convention on International Interests in Mobile Equipment on Matters Specific to Aircraft equipment, both signed in Cape Town, South Africa on November 16, 2001, together with the Regulations for the International Registry, the International Registry Procedures, and all other rules, amendments, supplements, revisions thereto (collectively the “Cape Town Treaty”), all as in effect on this date in the United States of America, as a Contracting State, as defined in the Cape Town Treaty (a “Contracting State”), and the requirements of Title 49 of the United States Code (the “Transportation Code”); and (ii) pertaining to the recordation of instruments and the registration of aircraft pursuant to the Transportation Code and the continued validity of interests under the Cape Town Treaty and the Transportation Code.

[¹This letter confirms that we filed the following described instruments with the Federal Aviation Administration (the “FAA”) today at the respective times noted below: (a) AC Form 8050-2 Aircraft Xxxx of Sale dated this date (the “FAA Xxxx of Sale”) by The Boeing Company (“Boeing”) to United Airlines, Inc. (the “Owner”) covering the Aircraft was filed at : _.M., C._.T.;

¹	For use when the Aircraft is purchased by United at the same time as the Mortgage is entered into and filed at the same time with the FAA.

(b) AC Form 8050-1 Aircraft Registration Application by the Owner covering the Aircraft was filed at : _.M., C._.T.; and

(c)]

[²This letter confirms that we filed with the Federal Aviation Administration (the “FAA”) today at __:__ _.M., C.S.T.,] Trust Indenture and Mortgage ___ dated as of this date (the “Trust Indenture”) by [¹the Owner] [²United Airlines, Inc. (the “Owner”)] in favor of Wilmington Trust, National Association, as Mortgagee (the “Mortgagee”), to which was attached Trust Indenture and Mortgage Supplement No. 1 dated this date (the “Indenture Supplement”) covering the Aircraft and the two model (described as model on the International Registry) aircraft engines with manufacturer’s serial numbers and (the “Engines”) [¹was filed at : _.M., C._.T.]

Based upon our examination of the above-described instruments and of such records of the FAA and the Priority Search Certificates (the “Priority Search Certificates”) issued by the International Registry as we deemed necessary to render this opinion and as were made available to us by the FAA and the International Registry, it is our opinion that:

(a)

based on the type certificate data sheets issued by the FAA, the Aircraft and the Engines constitute “aircraft objects” as defined by the Cape Town Treaty;

(b)

[¹the FAA Xxxx of Sale and ]the Trust Indenture with the Indenture Supplement attached [¹are] [²is] in due form for recording and [¹have] [²has] been duly filed for recordation with the FAA pursuant to and in accordance with the provisions of the Transportation Code;

(c)

[¹the Owner is owner of legal title to the Aircraft and all instruments necessary to cause the FAA in due course to issue to the Owner a Certificate of Aircraft Registration covering the Aircraft have been duly filed with the FAA pursuant to and in accordance with the provisions of the Transportation Code] [²the Owner is owner of legal title to the Aircraft, with a Certificate of Aircraft Registration duly issued to the Owner with an expiration date of , 202_, pursuant to and in accordance with the provisions of the Transportation Code];

(d)

the Aircraft and the Engines are free and clear of all Liens (as such term is defined in the Trust Indenture) of record with the FAA except the security interest created by the Trust Indenture, as supplemented by the Indenture Supplement;

²	For use when the Aircraft was previously delivered and the Mortgage is the only document entered into and filed with the FAA.

Page 2

(e)

the interest by the Owner to the Mortgagee created pursuant to and recognized by the Cape Town Treaty in the Trust Indenture, as supplemented by the Indenture Supplement (the “Indenture International Interest”), constitutes an International Interest as defined in the Cape Town Treaty with respect to the Aircraft and the Engines;

(f)

based on the Priority Search Certificate No. dated this date issued by the International Registry attached hereto as Exhibit B, the Aircraft is subject to: [¹(i) the Indenture International Interest assigned International Registry File No. ; and (ii) Sale dated this date by Boeing as seller to the Owner as buyer (the “Sale”) assigned International Registry File No. ] [²(i) the Sale dated , 201_, by The Boeing Company as seller to the Owner as buyer (the “Sale”) assigned International Registry File No. ; and (ii) International Interest dated this date by the Owner as debtor to the Mortgagee as creditor (the “Indenture International Interest”) assigned International Registry File No. ];

(g)

based on the Priority Search Certificate No. dated this date issued by the International Registry, attached hereto as Exhibit C, Engine is subject to: [¹(i) the Indenture International Interest assigned International Registry File No. ; and (ii) the Sale assigned International Registry File No. ] [²(i) the Sale assigned International Registry File No. ; and (ii) the Indenture International Interest assigned International Registry File No. ];

(h)

(i)

the Indenture International Interest is a duly registered first priority International Interest as defined in the Cape Town Treaty in favor of the Mortgagee in the Aircraft and the Engines, subject to the terms of the Cape Town Treaty;

(j)

the Sale is effective to transfer the interest of Boeing in the Aircraft and the Engines to the Owner and is effective against third parties in any Contracting State pursuant to and in accordance with the terms of the Cape Town Treaty;

(k)

the Trust Indenture, as supplemented by the Indenture Supplement, constitutes a valid, duly perfected mortgage and security interest in favor of the Mortgagee in the Aircraft and the Engines pursuant to and in accordance with the Transportation Code, subject to the terms of the Cape Town Treaty;

Page 3

(l)

no further registration with the International Registry of the Indenture International Interest or the Sale is required under the Cape Town Treaty and no filings or recordings of the Trust Indenture or the Indenture Supplement (other than the filings and recordings with the FAA which have been effected) are necessary to perfect and maintain the effectiveness and priority of the interests created thereunder; and

(m)

no authorization, approval, consent, license or order of, or registration with, or giving of notice to, the FAA Aircraft Registry or the International Registry is required for the valid authorization, delivery or performance of the Trust Indenture or the Indenture Supplement, or to maintain the effectiveness and priority thereof, except for such authorizations, approvals, consents, licenses, orders, registrations and notices as have been effected.

No opinion is herein expressed as to: (i) laws other than the federal laws of the United States; (ii) the validity or enforceability under local law of the Trust Indenture, as supplemented by the Indenture Supplement; and (iii) the recognition of the perfection of the security interest created by the Trust Indenture, as supplemented by the Indenture Supplement, as against third parties in any legal proceedings outside the United States. Since our examination was limited to records maintained by the FAA Aircraft Registry and the International Registry, our opinion does not cover liens which are perfected without the filing of notice thereof with the FAA and without the registration of notice thereof with the International Registry, such as federal tax liens, liens arising under Section 1368(a) of Title 29 of the United States Code and possessory artisans’ liens, and is subject to: (i) the accuracy of FAA personnel in the filing, indexing, posting, recording and additions to the Registry Modernization System of instruments filed with the FAA and in the search for encumbrance cross-reference index records for the Engines; (ii) the accuracy of the information contained in the Priority Search Certificates; and (iii) the inclusion of all registered interests associated with the Aircraft and the Engines in the Priority Search Certificates. We have assumed that the instruments in the records maintained by the FAA for the Aircraft and the Engines and the instruments supporting the registrations on the International Registry are sufficient under the relevant local law to create or terminate the interests they purport to create or terminate.

Very truly yours,

Xxxxx Xxxxx

SECTION 2.04. Method of Payment

(a) The Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due under each Equipment Note or hereunder will be payable in Dollars by wire transfer of immediately available funds not later than 12:30 PM, New York time, on the due date of payment to the Mortgagee at the Corporate Trust Office for distribution among the Note Holders in the manner provided herein, and payment of such amount by the Owner to the Mortgagee shall be deemed to satisfy the Owner’s obligation to make such payment. The Owner shall not have any responsibility for the distribution of such payment to any Note Holder. Notwithstanding the foregoing or any provision in any Equipment Note to the contrary, the Mortgagee will use reasonable efforts to pay or cause to be paid, if so directed in writing by any

Note Holder (with a copy to the Owner), all amounts paid by the Owner hereunder and under such holder’s Equipment Note or Equipment Notes to such holder or a nominee therefor (including all amounts distributed pursuant to Article III of this Trust Indenture) by transferring, or causing to be transferred, by wire transfer of immediately available funds in Dollars, prior to 2:00 p.m., New York City time, on the due date of payment, to an account maintained by such holder with a bank located in the continental United States the amount to be distributed to such holder, for credit to the account of such holder maintained at such bank. If the Mortgagee shall fail to make any such payment as provided in the immediately foregoing sentence after its receipt of funds at the place and prior to the time specified above, the Mortgagee, in its individual capacity and not as trustee, agrees to compensate such holders for loss of use of funds at Debt Rate until such payment is made and the Mortgagee shall be entitled to any interest earned on such funds until such payment is made. Any payment made hereunder shall be made without any presentment or surrender of any Equipment Note, except that, in the case of the final payment in respect of any Equipment Note, such Equipment Note shall be surrendered to the Mortgagee for cancellation promptly after such payment. Notwithstanding any other provision of this Trust Indenture to the contrary, the Mortgagee shall not be required to make, or cause to be made, wire transfers as aforesaid prior to the first Business Day on which it is practicable for the Mortgagee to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 12:30 PM, New York time, at the place of payment. Prior to the due presentment for registration of transfer of any Equipment Note, the Owner and the Mortgagee shall deem and treat the Person in whose name any Equipment Note is registered on the Equipment Note Register as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable with respect to such Equipment Note and for all other purposes, and none of the Owner or the Mortgagee shall be affected by any notice to the contrary. So long as any signatory to the Participation Agreement or nominee thereof shall be a registered Note Holder, all payments to it shall be made to the account of such Note Holder specified in Schedule 1 thereto and otherwise in the manner provided in or pursuant to the Participation Agreement unless it shall have specified some other account or manner of payment by notice to the Mortgagee consistent with this Section 2.04.

(b) The Mortgagee, as agent for the Owner, shall exclude and withhold at the appropriate rate from each payment of Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due hereunder or under each Equipment Note (and such exclusion and withholding shall constitute payment in respect of such Equipment Note) any and all United States withholding taxes, including, without limitation, any such withholding taxes imposed under FATCA applicable thereto as required by Law. The Mortgagee agrees to act as such withholding agent and, in connection therewith, whenever any present or future United States taxes or similar charges are required to be withheld with respect to any amounts payable hereunder or in respect of the Equipment Notes, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of the Note Holders, that it will file any necessary United States withholding tax returns or statements when due, and that as promptly as possible after the payment thereof it will deliver to each Note Holder (with a copy to the Owner) appropriate receipts showing the payment thereof, together with such additional documentary evidence as any such Note Holder may reasonably request from time to time.

If a Note Holder which is a Non-U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W-8BEN

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

Owner shall not have any liability for the failure of the Mortgagee to withhold taxes in the manner provided for herein or for any false, inaccurate or untrue evidence provided by any Note Holder hereunder.

SECTION 2.05. Application of Payments

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

First: to the payment of Make-Whole Amount, if any, with respect to such Equipment Note and any other amount (other than as covered by any of the following clauses) due hereunder or under such Equipment Note;

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

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

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

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

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

SECTION 2.07. Registration Transfer and Exchange of Equipment Notes

The Mortgagee shall keep a register (the “Equipment Note Register”) in which the Mortgagee shall provide for the registration of Equipment Notes and the registration of transfers of Equipment Notes. No such transfer shall be given effect unless and until registration hereunder shall have occurred. The Equipment Note Register shall be kept at the Corporate Trust Office of the Mortgagee. The Mortgagee is hereby appointed “Equipment Note Registrar” for the purpose of registering Equipment Notes and transfers of Equipment Notes as herein provided. A holder of any Equipment Note intending to exchange such Equipment Note shall surrender such Equipment Note to the Mortgagee at the Corporate Trust Office, together with a written request from the registered holder thereof for the issuance of a new Equipment Note, specifying, in the case of a surrender for transfer, the name and address of the new holder or holders. Upon surrender for registration of transfer of any Equipment Note, the Owner shall execute, and the Mortgagee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Equipment Notes of a like aggregate Original Amount and of the same Series. At the option of the Note Holder, Equipment Notes may be exchanged for other Equipment Notes of any authorized denominations of a like aggregate Original Amount, upon surrender of the Equipment Notes to be exchanged to the Mortgagee at the Corporate Trust Office. Whenever any Equipment Notes are so surrendered for exchange, the Owner shall execute, and the Mortgagee shall authenticate and deliver, the Equipment Notes which the Note Holder making the exchange is entitled to receive. All Equipment Notes issued upon any registration of transfer or exchange of Equipment Notes (whether under this Section 2.07 or under Section 2.08 hereof or otherwise under this Trust Indenture) shall be the valid obligations of the Owner evidencing the same respective obligations, and entitled to the

same security and benefits under this Trust Indenture, as the Equipment Notes surrendered upon such registration of transfer or exchange. Every Equipment Note presented or surrendered for registration of transfer, shall (if so required by the Mortgagee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Mortgagee duly executed by the Note Holder or such holder’s attorney duly authorized in writing, and the Mortgagee shall require evidence satisfactory to it as to the compliance of any such transfer with the Securities Act, and the securities Laws of any applicable state. The Mortgagee shall make a notation on each new Equipment Note of the amount of all payments of Original Amount previously made on the old Equipment Note or Equipment Notes with respect to which such new Equipment Note is issued and the date to which interest on such old Equipment Note or Equipment Notes has been paid. Interest shall be deemed to have been paid on such new Equipment Note to the date on which interest shall have been paid on such old Equipment Note, and all payments of the Original Amount marked on such new Equipment Note, as provided above, shall be deemed to have been made thereon. The Owner shall not be required to exchange any surrendered Equipment Notes as provided above during the ten-day period preceding the due date of any payment on such Equipment Note. The Owner shall in all cases deem the Person in whose name any Equipment Note shall have been issued and registered as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable by the Owner with respect to such Equipment Note and for all purposes until a notice stating otherwise is received from the Mortgagee and such change is reflected on the Equipment Note Register. The Mortgagee will promptly notify the Owner of each registration of a transfer of an Equipment Note. Any such transferee of an Equipment Note, by its acceptance of an Equipment Note, (i) agrees to the provisions of this Trust Indenture and the Participation Agreement applicable to Note Holders, including Sections 6.3, 6.4 and 9.1 thereof, and shall be deemed to have covenanted to the parties to the Participation Agreement as to the matters covenanted by the original Note Holder in the Participation Agreement and (ii) agrees to the restrictions set forth in Sections 4.1(a)(i) and 4.1(a)(iii) of the Intercreditor Agreement, and shall be deemed to have covenanted to the parties to the Intercreditor Agreement not to give any direction, or otherwise authorize, the Mortgagee to take any action that would violate Sections 4.1(a)(i) or 4.1(a)(iii) of the Intercreditor Agreement. Subject to compliance by the Note Holder and its transferee (if any) of the requirements set forth in this Section 2.07, Mortgagee and Owner shall use all reasonable efforts to issue new Equipment Notes upon transfer or exchange within 10 Business Days of the date an Equipment Note is surrendered for transfer or exchange.

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

If any Equipment Note shall become mutilated, destroyed, lost or stolen, the Owner shall, upon the written request of the holder of such Equipment Note, execute and the Mortgagee shall authenticate and deliver in replacement thereof a new Equipment Note, payable in the same Original Amount dated the same date and captioned as issued in connection with the Aircraft. If the Equipment Note being replaced has become mutilated, such Equipment Note shall be surrendered to the Mortgagee and a photocopy thereof shall be furnished to the Owner. If the Equipment Note being replaced has been destroyed, lost or stolen, the holder of such Equipment Note shall furnish to the Owner and the Mortgagee such security or indemnity as may be required by them to save the Owner and the Mortgagee harmless and evidence satisfactory to the Owner and the Mortgagee of the destruction, loss or theft of such Equipment Note and of the ownership thereof. If a “qualified institutional buyer” of the type referred to in paragraph

(a)(1)(i)(A), (B), (D) or (E) of Rule 144A under the Securities Act (a “QIB”) is the holder of any such destroyed, lost or stolen Equipment Note, then the written indemnity of such QIB, signed by an authorized officer thereof, in favor of, delivered to and in form reasonably satisfactory Owner shall be accepted as satisfactory indemnity and security and no further indemnity or security shall be required as a condition to the execution and delivery of such new Equipment Note. Subject to compliance by the Note Holder with the requirements set forth in this Section 2.08, Mortgagee and Owner shall use all reasonable efforts to issue new Equipment Notes within 10 Business Days of the date of the written request therefor from the Note Holder.

SECTION 2.09. Payment of Expenses on Transfer; Cancellation

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

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

SECTION 2.10. Mandatory Redemptions of Equipment Notes

On the date on which the Owner is required pursuant to Section 4.05 hereof to make payment for an Event of Loss with respect to the Airframe, all of the Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with all accrued interest thereon to the date of redemption and all other Secured Obligations (other than Related Secured Obligations) owed or then due and payable to the Note Holders but without Make-Whole Amount.

SECTION 2.11. Voluntary Redemptions of Equipment Notes

(a) All (but not less than all) of the Equipment Notes may be redeemed by the Owner upon at least 30 days’ revocable prior written notice to the Mortgagee and the Note Holders, and such Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with accrued interest thereon to the date of redemption and all other Secured Obligations (other than Related Secured Obligations) owed or then due and payable to the Note Holders plus Make-Whole Amount, if any, provided that no redemption shall be permitted under this Section 2.11(a) unless simultaneously with such redemption all Related Series AA Equipment Notes and Related Series A Equipment Notes shall also be redeemed.

(b) All (but not less than all) of the Series A Equipment Notes may be redeemed by the Owner upon at least 30 days’ revocable prior written notice to the Mortgagee and the Note Holders of such Series, and such Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with accrued interest thereon to the date of redemption and all other Secured Obligations (other than Related

Secured Obligations) owed or then due and payable to the Note Holders of such Series plus Make-Whole Amount, if any; provided that no redemption shall be permitted under this Section 2.11(b) unless the following conditions have been satisfied: (1) simultaneously with such redemption, the Related Series A Equipment Notes shall also be redeemed; and (2) simultaneously with such redemption, new Series A Equipment Notes shall be reissued in accordance with Section 4(a)(vi) of the Note Purchase Agreement and Section 9.1(c) of the Intercreditor Agreement.

SECTION 2.12. Redemptions; Notice of Redemption

(a) No redemption of any Equipment Note may be made except to the extent and in the manner expressly permitted by this Trust Indenture. No purchase of any Equipment Note may be made by the Mortgagee.

(b) Notice of redemption with respect to the Equipment Notes shall be given by the Mortgagee by first-class mail, postage prepaid, mailed not less than 20 nor more than 60 days prior to the applicable redemption date, to each Note Holder of such Equipment Notes to be redeemed, at such Note Holder’s address appearing in the Equipment Note Register; provided that such notice shall be revocable by written notice from the Owner to Mortgagee given not later than three days prior to the redemption date. All notices of redemption shall state: (1) the redemption date, (2) the applicable basis for determining the redemption price, (3) that on the redemption date, the redemption price will become due and payable upon each such Equipment Note, and that, if any such Equipment Notes are then outstanding, interest on such Equipment Notes shall cease to accrue on and after such redemption date, and (4) the place or places where such Equipment Notes are to be surrendered for payment of the redemption price.

(c) On or before the redemption date, the Owner (or any person on behalf of the Owner) shall, to the extent an amount equal to the redemption price for the Equipment Notes to be redeemed on the redemption date shall not then be held by the Mortgagee, deposit or cause to be deposited with the Mortgagee by 12:30 PM New York time on the redemption date in immediately available funds the redemption price of the Equipment Notes to be redeemed.

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

SECTION 2.13. Subordination

(a) The Owner, each Note Holder (by acceptance of its Equipment Notes of any Series) and each Related Note Holder (by acceptance of its Related Equipment Note), hereby agree that no payment or distribution shall be made on or in respect of the Secured Obligations owed to such Note Holder of such Series or owed to such Related Note Holder, including any payment or distribution of cash, property or securities after the commencement of a proceeding of the type referred to in Section 5.01(v), (vi) or (vii) hereof, except as expressly provided in Article III hereof.

(b) By the acceptance of its Equipment Notes of any Series (other than Series AA), each Note Holder of such Series agrees that in the event that such Note Holder, in its capacity as a Note Holder, shall receive any payment or distribution on any Secured Obligations in respect of such Series which it is not entitled to receive under this Section 2.13 or Article III hereof, it will hold any amount so received in trust for the Senior Holder (as defined in Section 2.13(c) hereof) and will forthwith turn over such payment to the Mortgagee in the form received to be applied as provided in Article III hereof. By the acceptance of its Related Equipment Notes (other than Related Series AA Equipment Notes), each Related Note Holder agrees that in the event that such Related Note Holder, in its capacity as a Related Note Holder, shall receive any payment or distribution pursuant to this Trust Indenture on any Related Secured Obligations which it is not entitled to receive under this Section 2.13 or Article III hereof, it will hold any amount so received in trust for the Senior Holder (as defined in Section 2.13(c) hereof) and will forthwith turn over such payment to the Mortgagee in the form received to be applied as provided in Article III hereof.

SECTION 3.07. Securities Account

In furtherance of the provisions of Section 3.03 of this Trust Indenture, WTNA agrees to act as an Eligible Institution under this Trust Indenture in accordance with the provisions of this Trust Indenture.

The Owner acknowledges that, by reason of the Mortgagee being the “entitlement holder” in respect of the Securities Account as provided above, the Mortgagee shall have the sole right and discretion, subject only to the terms of this Trust Indenture, to give all “entitlement orders” (as defined in Section 8-102(a)(8) of the NY UCC) with respect to the Securities Account and any and all financial assets and other property credited thereto to the exclusion of the Owner.

(iii) Install or permit any Permitted Lessee to install an Engine on an airframe owned by Owner or such Permitted Lessee, as the case may be, free and clear of all Liens, except (x) Permitted Liens and those that do not apply to the Engines, and (y) the rights of third parties under normal interchange or pooling agreements and arrangements of the type that would be permitted under Section 4.02(b)(i);

(iv) Install or permit any Permitted Lessee to install an Engine on an airframe leased to Owner or such Permitted Lessee, or purchased by Owner or such Permitted Lessee subject to a mortgage, security agreement, conditional sale or other secured financing arrangement, but only if (x) such airframe is free and clear of all Liens, except (A) the rights of the parties to such lease, or any such secured financing arrangement, covering such airframe and (B) Liens of the type permitted by clause (iii) above and (y) Owner or Permitted Lessee, as the case may be, shall have received from the lessor, mortgagee, secured party or conditional seller, in respect of such airframe, a written agreement (which may be a copy of the lease, mortgage, security agreement, conditional sale 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 such Engine being installed on such airframe at any time while such Engine is subject to the Lien of this Trust Indenture;

(v) Install or permit any Permitted Lessee to install an Engine on an airframe owned by Owner or such Permitted Lessee, leased to Owner or such Permitted Lessee, or purchased by Owner or such Permitted Lessee subject to a conditional sale or other security agreement under circumstances where neither clause (iii) or (iv) above is applicable; provided, however, that any such installation shall be deemed an Event of Loss with respect to such Engine, and Owner shall comply with Section 4.04(e) hereof in respect thereof;

(vi) Transfer or permit any Permitted Lessee to transfer possession of the Aircraft, Airframe or any Engine to the U.S. Government, in which event Owner shall promptly notify Mortgagee in writing of any such transfer of possession and, in the case of any transfer pursuant to CRAF, in such notification shall identify by name, address and telephone numbers the Contracting Office Representative or Representatives for the Military Airlift Command of the United States Air Force to whom notices must be given and to whom requests or claims must be made to the extent applicable under CRAF;

(vii) Enter into a charter or Wet Lease or other similar arrangement 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 the Owner’s obligations hereunder shall continue in full force and effect notwithstanding any such charter or Wet Lease or other similar arrangement;

(viii) So long as no Event of Default shall have occurred and be continuing, and subject to the provisions of the immediately following paragraph, enter into a lease with respect to the Aircraft, Airframe or any Engine to any Permitted Air Carrier that 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; provided that, in the case only of a lease to a Permitted Foreign Air Carrier, (A) the United States maintains diplomatic relations with the country of domicile of such Permitted Foreign Air Carrier (or, in the case of Taiwan, diplomatic relations at least as good as those in effect on the Closing Date) and (B) Owner shall have furnished Mortgagee a favorable opinion of counsel, reasonably satisfactory to Mortgagee, in the country of domicile of such Permitted Foreign Air Carrier, that (v) the terms of such lease are the legal, valid and binding obligations of the parties thereto enforceable under the laws of such jurisdiction, (w) it is not necessary for Mortgagee to register or qualify to do business in such jurisdiction, if not already so registered or qualified, as a result, in whole or in part, of the proposed lease, (x) Mortgagee’s Lien in respect of, the Aircraft, Airframe and Engines will be recognized in such jurisdiction, (y) the Laws of such jurisdiction of domicile require fair compensation by the government of such jurisdiction, payable in a currency freely convertible into Dollars, for the loss of title to the Aircraft, Airframe or Engines in the event of the requisition by such government of such title (unless Owner shall provide insurance in the amounts required with respect to hull insurance under this Trust Indenture covering the requisition of title to the Aircraft, Airframe or Engines by the government of such jurisdiction so long as the Aircraft, Airframe or Engines are subject to such lease) and (z) the agreement of such Permitted Air Carrier that its rights under the lease are subject and subordinate to all the terms of this Trust Indenture is enforceable against such Permitted Air Carrier under applicable law;

provided that (1) the rights of any transferee who receives possession by reason of a transfer permitted by any of clauses (i) through (viii) of this Section 4.02(b) (other than by a transfer of an Engine which is deemed an Event of Loss) shall be subject and subordinate to all the terms of this Trust Indenture, (2) the Owner shall remain primarily liable for the performance of all of the terms of this Trust Indenture and all the terms and conditions of this Trust Indenture and the other Operative Agreements shall remain in effect and (3) no lease or transfer of possession otherwise in compliance with this Section 4.02(b) shall (x) result in any registration or re-registration of an Aircraft, except to the extent permitted by Section 4.02(e) or the maintenance, operation or use thereof except in compliance with Sections 4.02(c) and 4.02(d) or (y) permit any action not permitted to the Owner hereunder.

In the case of any lease permitted under this Section 4.02(b), the Owner will include in such lease appropriate provisions which (t) make such lease expressly subject and subordinate to all of the terms of this Trust Indenture, including the rights of the Mortgagee to avoid such lease in the exercise of its rights to repossession of the Airframe and Engines hereunder; (u) require the Permitted Lessee to comply with the terms of Section 4.06; and (v) require that the Airframe or any Engine subject thereto be used in accordance with the limitations applicable to the Owner’s possession and use provided in this Trust Indenture. No lease permitted under this Section 4.02(b) shall be entered into unless (w) Owner shall provide written notice to Mortgagee (such notice in the event of a lease to a U.S. Air Carrier to be given promptly after entering into any such lease or, in the case of a lease to any other Permitted Air Carrier, 10 days in advance of entering into such lease); (x) Owner shall furnish to Mortgagee

evidence reasonably satisfactory to Mortgagee that the insurance required by Section 4.06 remains in effect; (y) all necessary documents shall have been duly filed, registered or recorded in such public offices as may be required fully to preserve the first priority security interest and International Interest (subject to Permitted Liens) of Mortgagee in the Aircraft, Airframe and Engines; and (z) Owner shall reimburse Mortgagee for all of its reasonable out-of-pocket fees and expenses, including, without limitation, reasonable fees and disbursements of counsel, incurred by Mortgagee in connection with any such lease. Except as otherwise provided herein and without in any way relieving the Owner from its primary obligation for the performance of its obligations under this Trust Indenture, the Owner may in its sole discretion permit a lessee to exercise any or all rights which the Owner would be entitled to exercise under Sections 4.02 and 4.04, and may cause a lessee to perform any or all of the Owner’s obligations under Article IV, and the Mortgagee agrees to accept actual and full performance thereof by a lessee in lieu of performance by the Owner.

Mortgagee hereby agrees, and each Note Holder and Related Note Holder by acceptance of an Equipment Note and a Related Equipment Note, respectively, agrees, for the benefit of each lessor, conditional seller, indenture trustee or secured party of any engine leased to, or purchased by, Owner or any Permitted Lessee subject to a lease, conditional sale, trust indenture or other security agreement that Mortgagee, each Note Holder and Related Note Holder and their respective successors and assigns will not acquire or claim, as against such lessor, conditional seller, indenture trustee or secured party, any right, title or interest in any engine as the result of such engine being installed on the Airframe at any time while such engine is subject to such lease, conditional sale, trust indenture or other security agreement and owned by such lessor or conditional seller or subject to a trust indenture or security interest in favor of such indenture trustee or secured party.

(c) Operation and Use. So long as the Aircraft, Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall not operate, use or locate the Aircraft, Airframe or any Engine, or allow the Aircraft, Airframe or any Engine to be operated, used or located, (i) in any area excluded from coverage by any insurance required by the terms of Section 4.06, except in the case of a requisition by the U.S. Government where the Owner 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 4.06 covering such area, or (ii) in any recognized area of hostilities unless covered in accordance with Section 4.06 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 Owner diligently and in good faith proceeds to remove the Aircraft from such area. So long as the Aircraft, the Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall not permit such Aircraft, Airframe or any Engine, as the case may be, 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 Owner or Permitted Lessee, as the case may be, 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 Owner or Permitted Lessee in any reasonable manner which does not involve any material risk of the sale, forfeiture or loss of the Aircraft, Airframe or any Engine, any material risk of criminal liability or material civil penalty against Mortgagee or impair the Mortgagee’s security interest or International Interest in the Aircraft, Airframe or any Engine.

(d) Maintenance and Repair. So long as the Aircraft, Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall cause the Aircraft, Airframe and each Engine to be maintained, serviced, repaired and overhauled in accordance with (i) maintenance standards required by or substantially equivalent to those required by the FAA, the EASA or the central aviation authority of Canada or Japan for the Aircraft, Airframe and Engines, so as to (A) keep the Aircraft, the Airframe and each Engine in as good operating condition as on the Closing Date, ordinary wear and tear excepted, (B) 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, except during (x) temporary periods of storage in accordance with applicable regulations, (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 (ii) except during periods when a Permitted Lease is in effect, the same standards as Owner uses with respect to similar aircraft of similar size in its fleet operated by Owner 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 (it being understood that this clause (ii) shall not limit Owner’s obligations under the preceding clause (i)). Owner further agrees that the Aircraft, 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, 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 Owner 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 a material risk of sale, loss or forfeiture of the Aircraft, the Airframe or any Engine or the interest of Mortgagee therein, or any material risk of criminal liability or material civil penalty against Mortgagee. The Owner shall maintain or cause to be maintained the Aircraft Documents in the English language.

(e) Registration. The Owner on or prior to the date of the Closing shall cause the Aircraft to be duly registered in its name under the Act and except as otherwise permitted by this Section 4.02(e) at all times thereafter shall cause the Aircraft to remain so registered. So long as no Special Default or Event of Default shall have occurred and be continuing, Owner may, by written notice to Mortgagee, request to change the country of registration of the Aircraft. Any such change in registration shall be effected only in compliance with, and subject to all of the conditions set forth in, Section 6.4.5 of the Participation Agreement. Unless this Trust Indenture has been discharged, Owner shall also cause this Trust Indenture 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 (except to the extent such perfection or priority cannot be maintained solely as a result of the failure by Mortgagee to execute and deliver any necessary documents). Unless the Lien of this Indenture has been discharged, Owner shall cause the International Interest granted under this Indenture in favor of the Mortgagee in each Airframe and Engine to be registered on the International Registry as an International Interest on such Airframe and Engine, subject to the Mortgagee providing its consent to the International Registry with respect thereto, and shall cause the sale to Owner of the Airframe and each Engine on the Delivery Date to be registered on the International Registry.

(f) Markings. If permitted by applicable Law, on or reasonably promptly after the Closing Date, Owner 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 Wilmington Trust, National Association, not in its individual capacity but solely as Mortgagee.” Such placards may be removed temporarily, if necessary, in the course of maintenance of the Airframe or Engines. If any such placard is damaged or becomes illegible, Owner shall promptly replace it with a placard complying with the requirements of this Section.

SECTION 4.03. Inspection

(a) At all reasonable times, so long as the Aircraft is subject to the Lien of this Trust Indenture, Mortgagee and its authorized representatives (the “Inspecting Parties”) may (not more than once every 12 months unless an Event of Default has occurred and is continuing then such inspection right shall not be so limited) inspect the Aircraft, Airframe and Engines (including without limitation, the Aircraft Documents) and any such Inspecting Party may make copies of such Aircraft Documents not reasonably deemed confidential by Owner or such Permitted Lessee.

(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 Owner’s or any Permitted Lessee’s maintenance and operation of the Aircraft, Airframe and Engines.

(c) With respect to such rights of inspection, Mortgagee shall not 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 (including the cost of any copies made in accordance with Section 4.03(a)).

SECTION 4.04. Replacement and Pooling of Parts, Alterations, Modifications and Additions; Substitution Rights

(a) Replacement of Parts. Except as otherwise provided herein, so long as the Airframe or Engine is subject to the Lien of this Indenture, Owner, at its own cost

and expense, will, or will cause a Permitted Lessee to, at its own cost and expense, promptly replace (or cause to be replaced) all Parts which may from time to time be incorporated or installed in or attached to the Aircraft, Airframe or any Engine and which may from time to time become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use for any reason whatsoever. In addition, Owner may, at its own cost and expense, or may permit a Permitted Lessee at its own cost and expense to, remove (or cause to be removed) in the ordinary course of 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, however, that Owner, except as otherwise provided herein, at its own cost and expense, will, or will cause a Permitted Lessee at its own cost and expense to, replace such Parts as promptly as practicable. All replacement parts shall be free and clear of all Liens, except for Permitted Liens and pooling arrangements to the extent permitted by Section 4.04(c) below (and except in the case of replacement property temporarily installed on an emergency basis) and shall be in good operating condition and have a value and utility not less than the value and utility of the Parts replaced (assuming such replaced Parts were in the condition required hereunder).

(b) 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 Trust Indenture, no matter where located, until such time as such Part shall be 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. Immediately upon any replacement part becoming incorporated or installed in or attached to such Airframe or any Engine as provided in Section 4.04(a), without further act, (i) the replaced Part shall thereupon be free and clear of all rights of the Mortgagee and shall no longer be deemed a Part hereunder, and (ii) such replacement part shall become a Part subject to this Trust Indenture and be deemed part of such Airframe or any Engine, as the case may be, for all purposes hereof to the same extent as the Parts originally incorporated or installed in or attached to such Airframe or any Engine.

(c) Pooling of Parts. Any Part removed from the Aircraft, Airframe or an Engine may be subjected by the Owner or a Permitted Lessee to a normal pooling arrangement customary in the airline industry and entered into in the ordinary course of business of Owner 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 Sections 4.04(a) and 4.04(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 the Owner or a Permitted Lessee, at its own cost and expense, as promptly thereafter as reasonably possible, either (i) causes such replacement part to become subject to the Lien of this Trust Indenture, free and clear of all Liens except Permitted Liens, at which time such replacement part shall become a Part or (ii) replaces (or causes to be replaced) such replacement part by incorporating or installing in or attaching to the Aircraft, Airframe or any Engine a further replacement part owned by the Owner free and clear of all Liens except Permitted Liens and which shall become subject to the Lien of this Trust Indenture in accordance with Section 4.04(b).

(d) Alterations, Modifications and Additions. The Owner shall, or shall cause a Permitted Lessee to, make (or cause to be made) alterations and modifications in and additions to the Aircraft, Airframe and each Engine 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 however, that the Owner 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 materially adversely affect Mortgagee’s interest in the Aircraft, does not impair the Mortgagee’s security interest or International Interest in the Aircraft and does not involve any material risk of sale, forfeiture or loss of the Aircraft or the interest of Mortgagee therein, or any material risk of material civil penalty or any material risk of criminal liability being imposed on Mortgagee or the holder of any Equipment Note. In addition, the Owner, at its own expense, may, or may permit a Permitted Lessee at its own cost and expense to, from time to time make or cause to be made such alterations and modifications in and additions to the Airframe or any Engine (each an “Optional Modification”) as the Owner or such Permitted Lessee may deem desirable in the proper conduct of its business including, without limitation, removal of Parts which Owner deems are obsolete or no longer suitable or appropriate for use in the Aircraft, Airframe or such Engine; provided, however, that no such Optional Modification shall (i) materially 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 prior to such Optional Modification (assuming the Aircraft or such Engine was in the condition required by this Trust Indenture immediately prior to such Optional Modification) or (ii) cause the Aircraft to cease to have the applicable standard certificate of airworthiness except that such certificate of airworthiness temporarily may be replaced by an experimental certificate during the process of implementing and testing such Optional Modification and securing related FAA re-certification of the Aircraft. All Parts incorporated or installed in or attached to any Airframe or any Engine as the result of any alteration, modification or addition effected by the Owner shall be free and clear of any Liens except Permitted Liens and become subject to the Lien of this Trust Indenture; provided that the Owner or any Permitted Lessee may, at any time so long as the Airframe or any Engine is subject to the Lien of this Trust Indenture, 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 the terms of Section 4.02(d) or the first sentence of this Section 4.04(d) and (iii) such Part can be removed from such Airframe or any Engine without materially 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 by the Owner, assuming the Aircraft was otherwise maintained in the condition required by this Trust Indenture and such Removable Part had not been incorporated or installed in or attached to the Aircraft, Airframe or such Engine. Upon the removal by the Owner of any such Part as above provided in this Section 4.04(d), title thereto shall, without further act, be free and clear of all rights of the Mortgagee and such Part shall no longer be deemed a Part hereunder. Removable Parts may be leased from or financed by third parties other than Mortgagee.

(e) Substitution of Engines. Upon the occurrence of an Event of Loss with respect to an Engine under circumstances in which an Event of Loss with respect to the Airframe has not occurred, Owner shall promptly (and in any event within 15 days after such occurrence) give the Mortgagee written notice of such Event of Loss. The Owner shall have the right at its option at any time, on at least 5 Business Days’ prior notice to the Mortgagee, to substitute, and if an Event of Loss shall have occurred with respect to an Engine under circumstances in which an Event of Loss with respect to the Airframe has not occurred, shall within 60 days of the occurrence of such Event of Loss substitute, a Replacement Engine for any Engine. In such event, immediately upon the effectiveness of such substitution and without further act, (i) the replaced Engine shall thereupon be free and clear of all rights of the Mortgagee and the Lien of this Trust Indenture and shall no longer be deemed an Engine hereunder and (ii) such Replacement Engine shall become subject to this Trust Indenture and be deemed part of the Aircraft for all purposes hereof to the same extent as the replaced Engine. Such Replacement Engine shall be an engine manufactured by Engine Manufacturer that is the same model as the Engine to be replaced thereby, or an improved model, 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) at least equal to the Engine to be replaced thereby (assuming that such Engine had been maintained in accordance with this Trust Indenture). The Owner’s right to make a replacement hereunder shall be subject to the fulfillment (which may be simultaneous with such replacement) of the following conditions precedent at the Owner’s sole cost and expense, and the Mortgagee agrees to cooperate with the Owner to the extent necessary to enable it to timely satisfy such conditions:

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

(A) a Trust Indenture Supplement covering the Replacement Engine, which shall have been duly filed for recordation pursuant to the Act or such other applicable law of the jurisdiction other than the United States in which the Aircraft of which such Engine is a part is registered in accordance with Section 4.02(e), as the case may be;

(B) a full warranty xxxx of sale (as to title), covering the Replacement Engine, executed by the former owner thereof in favor of the Owner (or, at the Owner’s option, other evidence of the Owner’s ownership of such Replacement Engine, reasonably satisfactory to the Mortgagee); and

(C) UCC financing statements covering the security interests created by this Trust Indenture (or 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 deemed necessary or desirable by counsel for the Mortgagee to protect the security interests of the Mortgagee in the Replacement Engine;

(ii) the Owner shall cause to be delivered to the Mortgagee an opinion of counsel to the effect that the Lien of this Trust Indenture continues to be in full force and effect with respect to the Replacement Engine and such evidence of compliance with the insurance provisions of Section 4.06 with respect to such Replacement Engine as Mortgagee shall reasonably request;

(iii) the Owner shall have furnished to Mortgagee an opinion of Owner’s aviation law counsel reasonably satisfactory to Mortgagee and addressed to Mortgagee as to the due filing for recordation of the Trust Indenture Supplement with respect to such Replacement Engine under the Act or such other applicable law of the jurisdiction other than the United States in which the Aircraft is registered in accordance with Section 4.02(e), as the case may be, and the registration (which Owner shall have caused to be effected) with the International Registry of the sale to Owner of such Replacement Engine (if occurring after February 28, 2006) and the International Interest granted under such Trust Indenture Supplement with respect to such Replacement Engine; and

(iv) the Owner shall have furnished to Mortgagee a certificate of a qualified aircraft engineer (who may be an employee of Owner) certifying that such Replacement Engine has a value and utility and remaining useful life (without regard to hours and cycles remaining until overhaul) at least equal to the Engine so replaced (assuming that such Engine had been maintained in accordance with this Trust Indenture).

Upon satisfaction of all conditions to such substitution, (x) the Mortgagee shall execute and deliver to the Owner such documents and instruments, prepared at the Owner’s expense, as the Owner shall reasonably request to evidence the release of such replaced Engine from the Lien of this Trust Indenture, (y) the Mortgagee shall assign to the Owner all claims it may have against any other Person relating to any Event of Loss giving rise to such substitution and (z) the Owner shall receive all insurance proceeds (other than those reserved to others under Section 4.06(b)) and proceeds in respect of any Event of Loss giving rise to such replacement to the extent not previously applied to the purchase price of the Replacement Engine as provided in Section 4.05(d).

SECTION 4.05. Loss, Destruction or Requisition

(a) Event of Loss With Respect to the Airframe. Upon the occurrence of an Event of Loss with respect to the Airframe, the Owner shall promptly (and in any event within 15 days after such occurrence) give the Mortgagee written notice of such Event of Loss.

(i) if Owner elects to replace the Airframe, Owner shall, subject to the satisfaction of the conditions contained in Section 4.05(c), as promptly as possible and in any event within 120 days after the occurrence of such Event of Loss, cause to be subjected to the Lien of this Trust Indenture, in replacement of the Airframe with respect to which the Event of Loss occurred, a Replacement Airframe and, if any Engine shall have been installed on the Airframe when it suffered the Event of Loss, a Replacement Engine therefor,

such Replacement Airframe and Replacement Engines to be free and clear of all Liens except Permitted Liens and to have a value, utility and remaining useful life (without regard to hours or cycles remaining until the next regular maintenance check) at least equal to the Airframe or Engine, as the case may be, to be replaced thereby (assuming that such Airframe or Engine had been maintained in accordance with this Trust Indenture); provided that if the Owner shall not perform its obligation to effect such replacement under this clause (i) during the 120-day period of time provided herein, it shall pay the amounts required to be paid pursuant to and within the time frame specified in clause (ii) below; or

(ii) if Owner elects to make a payment in respect of such Event of Loss of the Airframe, Owner shall make a payment to the Mortgagee for purposes of redeeming Equipment Notes in accordance with Section 2.10 hereof on a date on or before the Business Day next following the earlier of (x) the 120th day following the date of the occurrence of such Event of Loss, and (y) the fourth Business Day following the receipt of insurance proceeds with respect to such Event of Loss (but in any event not earlier than the date of Owner’s election under Section 4.05(a) to make payment under this Section 4.05 (a)(ii)); and upon such payment and payment of all other Secured Obligations then due and payable, the Mortgagee shall, at the cost and expense of the Owner, release from the Lien of this Trust Indenture the Airframe and the Engines, by executing and delivering to the Owner all documents and instruments as the Owner may reasonably request to evidence such release.

(b) Effect of Replacement. Should the Owner have provided a Replacement Airframe and Replacement Engines, if any, as provided for in Section 4.05(a)(i), (i) the Lien of this Trust Indenture shall continue with respect to such Replacement Airframe and Replacement Engines, if any, as though no Event of Loss had occurred; (ii) the Mortgagee shall, at the cost and expense of the Owner, release from the Lien of this Trust Indenture the replaced Airframe and Engines, if any, by executing and delivering to the Owner such documents and instruments as the Owner may reasonably request to evidence such release; and (iii) in the case of a replacement upon an Event of Loss, the Mortgagee shall assign to the Owner all claims the Mortgagee may have against any other Person arising from the Event of Loss and the Owner shall receive all insurance proceeds (other than those reserved to others under Section 4.06(b)) and proceeds from any award in respect of condemnation, confiscation, seizure or requisition, including any investment interest thereon, to the extent not previously applied to the purchase price of the Replacement Airframe and Replacement Engines, if any, as provided in Section 4.05(d).

(c) Conditions to Airframe and Engine Replacement. The Owner’s right to substitute a Replacement Airframe and Replacement Engines, if any, as provided in Section 4.05(a)(i) shall be subject to the fulfillment, at the Owner’s sole cost and expense, in addition to the conditions contained in such Section 4.05(a)(i), of the following conditions precedent:

(a) Owner’s Obligation to Insure. Owner 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 4.06 shall limit or prohibit (a) Owner 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, however, that no insurance may be obtained or maintained that would limit or otherwise adversely affect the coverage of any insurance required to be obtained or maintained by Owner pursuant to this Section 4.06 and Annex B.

(c) Indemnification by Government in Lieu of Insurance. Mortgagee agrees to 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 the written consent of Mortgagee, 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 Owner (or any Permitted Lessee) may continue to maintain, in accordance with this Section 4.06, 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 4.06; provided that the provisions of Section D of Annex B shall not apply to an indemnity or insurance provided by the U.S. Government in lieu of insurance required by Section C of Annex B, except to the extent the U.S. Government makes such provisions generally available to covered airlines.

(d) Application of Insurance Proceeds.

All proceeds of insurance required to be maintained by Owner, in accordance with Section 4.06 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, Airframe or any Engine will be applied in payment (or to reimburse Owner) 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, Owner.

SECTION 4.07. Merger of Owner

(a) In General. Owner shall not consolidate with or merge into any other person under circumstances in which Owner is not the surviving corporation, or convey, transfer or lease in one or more transactions all or substantially all of its assets to any other person, unless:

(i) 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;

(ii) such person executes and delivers to Mortgagee a duly authorized, legal, valid, binding and enforceable 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 Owner;

(iii) if the Aircraft is, at the time, registered with the FAA, such person makes such filings and recordings with the FAA pursuant to the Act or if the Aircraft is, at the time, not registered with FAA, such person makes such filings and recordings with the applicable Aviation Authority as shall be necessary to evidence such consolidation or merger;

(iv) such person makes such registrations with the International Registry as shall be permitted to evidence such consolidation or merger; and

(v) immediately after giving effect to such consolidation or merger no Event of Default shall have occurred and be continuing.

(b) Effect of Merger. Upon any such consolidation or merger of Owner with or into, or the conveyance, transfer or lease by Owner of all or substantially all of its assets to, any Person in accordance with this Section 4.07, such Person will succeed to, and be substituted for, and may exercise every right and power of, Owner under the Operative Agreements with the same effect as if such person had been named as “Owner” therein. No such consolidation or merger, or conveyance, transfer or lease, shall have the effect of releasing Owner or such Person from any of the obligations, liabilities, covenants or undertakings of Owner under this Trust Indenture.

SECTION 5.02. Remedies

(a) If an Event of Default shall have occurred and be continuing and so long as the same shall continue unremedied, then and in every such case the Mortgagee may exercise any or all of the rights and powers and pursue any and all of the remedies pursuant to this Article V and shall have and may exercise all of the rights and remedies of a secured party under the Uniform Commercial Code or of a chargee under the Cape Town Treaty and may take possession of all or any part of the properties covered or intended to be covered by the Lien

created hereby or pursuant hereto and may exclude the Owner and all persons claiming under it wholly or partly therefrom; provided, that the Mortgagee shall give the Owner twenty days’ prior written notice of its intention to sell the Aircraft. Without limiting any of the foregoing, it is understood and agreed that the Mortgagee may exercise any right of sale of the Aircraft available to it, even though it shall not have taken possession of the Aircraft and shall not have possession thereof at the time of such sale.

(b) If an Event of Default shall have occurred and be continuing, then and in every such case the Mortgagee may (and shall, upon receipt of a written demand therefor from a Majority in Interest of Note Holders), at any time, by delivery of written notice or notices to the Owner, declare all the Equipment Notes to be due and payable, whereupon the unpaid Original Amount of all Equipment Notes then outstanding, together with accrued but unpaid interest thereon (without Make-Whole Amount) and other amounts due thereunder or otherwise payable hereunder, shall immediately become due and payable without presentment, demand, protest or notice, all of which are hereby waived; provided that if an Event of Default referred to in clause (v), (vi) or (vii) of Section 5.01 hereof shall have occurred, then and in every such case the unpaid Original Amount then outstanding, together with accrued but unpaid interest (without Make-Whole Amount) and all other amounts due hereunder and under the Equipment Notes shall immediately and without further act become due and payable without presentment, demand, protest or notice, all of which are hereby waived.

This Section 5.02(b), however, is subject to the condition that, if at any time after the Original Amount of the Equipment Notes shall have become so due and payable, and before any judgment or decree for the payment of the money so due, or any thereof, shall be entered, all overdue payments of interest upon the Equipment Notes and all other amounts payable hereunder or under the Equipment Notes (except the Original Amount of the Equipment Notes and any Make-Whole Amount which by such declaration shall have become payable) shall have been duly paid, and every other Default and Event of Default with respect to any covenant or provision of this Trust Indenture shall have been cured, then and in every such case a Majority in Interest of Note Holders may (but shall not be obligated to), by written instrument filed with the Mortgagee, rescind and annul the Mortgagee’s declaration (or such automatic acceleration) and its consequences; but no such rescission or annulment shall extend to or affect any subsequent Default or Event of Default or impair any right consequent thereon.

(c) The Note Holders shall be entitled, at any sale pursuant to this Section 5.02, to credit against any purchase price bid at such sale by such holder all or any part of the unpaid obligations owing to such Note Holder and secured by the Lien of this Trust Indenture (only to the extent that such purchase price would have been paid to such Note Holder pursuant to Article III hereof if such purchase price were paid in cash and the foregoing provisions of this subsection (c) were not given effect).

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

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

SECTION 5.03. Return of Aircraft, Etc.

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

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

SECTION 5.04. Remedies Cumulative

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

SECTION 5.05. Discontinuance of Proceedings

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

SECTION 5.06. Waiver of Past Defaults

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

SECTION 5.07. Appointment of Receiver

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

SECTION 5.08. Mortgagee Authorized to Execute Bills of Sale, Etc.

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

SECTION 5.09. Rights of Note Holders to Receive Payment

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

ARTICLE VI

DUTIES OF THE MORTGAGEE

SECTION 6.01. Notice of Event of Default

If the Mortgagee shall have Actual Knowledge of an Event of Default or of a Default arising from a failure to pay any installment of principal and interest on any Equipment Note, the Mortgagee shall give prompt written notice thereof to each Note Holder. Subject to the terms of Sections 5.06, 6.02 and 6.03 hereof, the Mortgagee shall take such action, or refrain from taking such action, with respect to such Event of Default or Default (including with respect to the exercise of any rights or remedies hereunder) as the Mortgagee shall be instructed in writing by a Majority in Interest of Note Holders. Subject to the provisions of Section 6.03, if the Mortgagee shall not have received instructions as above provided within 20 days after mailing notice of such Event of Default to the Note Holders, the Mortgagee may, subject to instructions thereafter received pursuant to the preceding provisions of this Section 6.01, take such action, or refrain from taking such action, but shall be under no duty to take or refrain from taking any action, with respect to such Event of Default or Default as it shall determine advisable in the best interests of the Note Holders; provided, however, that the Mortgagee may not sell the Aircraft or any Engine without the consent of a Majority in Interest of Note Holders. For all purposes of this Trust Indenture, in the absence of Actual Knowledge on the part of the Mortgagee, the Mortgagee shall not be deemed to have knowledge of a Default or an Event of Default (except, the failure of Owner to pay any installment of principal or interest within one Business Day after the same shall become due, which failure shall constitute knowledge of a Default) unless notified in writing by the Owner or one or more Note Holders.

SECTION 6.02. Action Upon Instructions; Certain Rights and Limitations

Subject to the terms of Sections 5.02(a), 5.06, 6.01 and 6.03 hereof, upon the written instructions at any time and from time to time of a Majority in Interest of Note Holders, the Mortgagee shall, subject to the terms of this Section 6.02, take such of the following actions as may be specified in such instructions: (i) give such notice or direction or exercise such right, remedy or power hereunder as shall be specified in such instructions and (ii) give such notice or direction or exercise such right, remedy or power hereunder with respect to any part of the Collateral as shall be specified in such instructions; it being understood that without the written instructions of a Majority in Interest of Note Holders, the Mortgagee shall not, except as provided in Section 6.01, approve any such matter as satisfactory to the Mortgagee.

The Mortgagee will execute and the Owner will file such continuation statements with respect to financing statements relating to the security interest created hereunder in the Collateral as may be specified from time to time in written instructions of a Majority in Interest of Note Holders (which instructions shall be accompanied by the form of such continuation statement so to be filed). The Mortgagee will furnish to each Note Holder, promptly upon receipt thereof, duplicates or copies of all reports, notices, requests, demands, certificates and other instruments furnished to the Mortgagee hereunder.

SECTION 6.03. Indemnification

The Mortgagee shall not be required to take any action or refrain from taking any action under Section 6.01 (other than the first sentence thereof), 6.02 or Article V hereof unless the Mortgagee shall have been indemnified to its reasonable satisfaction against any liability, cost or expense (including counsel fees) which may be incurred in connection therewith pursuant to a written agreement with one or more Note Holders. The Mortgagee agrees that it shall look solely to the Note Holders for the satisfaction of any indemnity (except expenses for foreclosure of the type referred to in clause “First” of Section 3.03 hereof) owed to it pursuant to this Section 6.03. The Mortgagee shall not be under any obligation to take any action under this Trust Indenture or any other Operative Agreement and nothing herein or therein shall require the Mortgagee to expend or risk its own funds or otherwise incur the risk of any financial liability in the performance of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it (the written indemnity of any Note Holder who is a QIB, signed by an authorized officer thereof, in favor of, delivered to and in form reasonably satisfactory to the Mortgagee shall be accepted as reasonable assurance of adequate indemnity). The Mortgagee shall not be required to take any action under Section 6.01 (other than the first sentence thereof) or 6.02 or Article V hereof, nor shall any other provision of this Trust Indenture or any other Operative Agreement be deemed to impose a duty on the Mortgagee to take any action, if the Mortgagee shall have been advised by counsel that such action is contrary to the terms hereof or is otherwise contrary to Law.

SECTION 6.04. No Duties Except as Specified in Trust Indenture or Instructions

The Mortgagee shall not have any duty or obligation to use, operate, store, lease, control, manage, sell, dispose of or otherwise deal with the Aircraft or any other part of the Collateral, or to otherwise take or refrain from taking any action under, or in connection with,

this Trust Indenture or any part of the Collateral, except as expressly provided by the terms of this Trust Indenture or as expressly provided in written instructions from Note Holders as provided in this Trust Indenture; and no implied duties or obligations shall be read into this Trust Indenture against the Mortgagee. The Mortgagee agrees that it will in its individual capacity and at its own cost and expense (but without any right of indemnity in respect of any such cost or expense under Section 8.01 hereof), promptly take such action as may be necessary duly to discharge all liens and encumbrances on any part of the Collateral which result from claims against it in its individual capacity not related to the administration of the Collateral or any other transaction pursuant to this Trust Indenture or any document included in the Collateral.

SECTION 6.05. No Action Except Under Trust Indenture or Instructions

The Mortgagee shall not be liable for any loss resulting from any investment required to be made by it under this Trust Indenture other than by reason of its willful misconduct or gross negligence or negligence in the handling of funds, and any such investment may be sold (without regard to its maturity) by the Mortgagee without instructions whenever such sale is necessary to make a distribution required by this Trust Indenture.

SUCCESSOR AND SEPARATE TRUSTEES

SECTION 9.01. Resignation of Mortgagee; Appointment of Successor

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

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

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

(d) Any corporation into which the Mortgagee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Mortgagee shall be a party, or any corporation to which substantially all the corporate trust business of the Mortgagee may be transferred, shall, subject to the terms of paragraph (c) of this Section 9.01, be a successor Mortgagee and the Mortgagee under this Trust Indenture without further act.

(e) The Owner consents to any change in the identity of the Mortgagee on the International Registry occasioned by provisions of this Section 9.01, and if required by the International Registry to reflect such change, will provide its consent thereto.

SECTION 9.02. Appointment of Additional and Separate Trustees

(a) Whenever (i) the Mortgagee shall deem it necessary or desirable in order to conform to any Law of any jurisdiction in which all or any part of the Collateral shall be situated or to make any claim or bring any suit with respect to or in connection with the Collateral, this Trust Indenture, any other Indenture Agreement, the Equipment Notes or any of the transactions contemplated by the Participation Agreement, (ii) the Mortgagee shall be advised by counsel satisfactory to it that it is so necessary or prudent in the interests of the Note Holders (and the Mortgagee shall so advise the Owner), or (iii) the Mortgagee shall have been requested to do so by a Majority in Interest of Note Holders, then in any such case, the Mortgagee and, upon the written request of the Mortgagee, the Owner, shall execute and deliver an indenture supplemental hereto and such other instruments as may from time to time be necessary or advisable either (1) to constitute one or more bank or trust companies or one or more persons approved by the Mortgagee, either to act jointly with the Mortgagee as additional trustee or trustees of all or any part of the Collateral, or to act as separate trustee or trustees of all or any part of the Collateral, in each case with such rights, powers, duties and obligations consistent with this Trust Indenture as may be provided in such supplemental indenture or other instruments as the Mortgagee or a Majority in Interest of Note Holders may deem necessary or advisable, or (2) to clarify, add to or subtract from the rights, powers, duties and obligations theretofore granted any such additional or separate trustee, subject in each case to the remaining provisions of this Section 9.02. If the Owner shall not have taken any action requested of it under this Section 9.02(a) that is permitted or required by its terms within 15 days after the receipt of a written request from the Mortgagee so to do, or if an Event of Default shall have occurred and be continuing, the Mortgagee may act under the foregoing provisions of this Section 9.02(a) without the concurrence of the Owner, and the Owner hereby irrevocably appoints (which appointment is coupled with an interest) the Mortgagee, its agent and attorney-in-fact to act for it under the foregoing provisions of this Section 9.02(a) in either of such contingencies. The Mortgagee

may, in such capacity, execute, deliver and perform any such supplemental indenture, or any such instrument, as may be required for the appointment of any such additional or separate trustee or for the clarification of, addition to or subtraction from the rights, powers, duties or obligations theretofore granted to any such additional or separate trustee. In case any additional or separate trustee appointed under this Section 9.02(a) shall die, become incapable of acting, resign or be moved, all the assets, property, rights, powers, trusts, duties and obligations of such additional or separate trustee shall revert to the Mortgagee until a successor additional or separate trustee is appointed as provided in this Section 9.02(a).

(b) No additional or separate trustee shall be entitled to exercise any of the rights, powers, duties and obligations conferred upon the Mortgagee in respect of the custody, investment and payment of monies and all monies received by any such additional or separate trustee from or constituting part of the Collateral or otherwise payable under any Operative Agreement to the Mortgagee shall be promptly paid over by it to the Mortgagee. All other rights, powers, duties and obligations conferred or imposed upon any additional or separate trustee shall be exercised or performed by the Mortgagee and such additional or separate trustee jointly except to the extent that applicable Law of any jurisdiction in which any particular act is to be performed renders the Mortgagee incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations (including the holding of title to all or part of the 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 the Mortgagee or a Majority in Interest of Note Holders. No trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder, except that the Mortgagee shall be liable for the consequences of its lack of reasonable care in selecting, and the Mortgagee’s own actions in acting with, any additional or separate trustee. Each additional or separate trustee appointed pursuant to this Section 9.02 shall be subject to, and shall have the benefit of Articles V through IX and Article XI hereof insofar as they apply to the Mortgagee. The powers of any additional or separate trustee appointed pursuant to this Section 9.02 shall not in any case exceed those of the Mortgagee hereunder.

(c) If at any time the Mortgagee shall deem it no longer necessary or in order to conform to any such Law or take any such action or shall be advised by such counsel that it is no longer so necessary or desirable in the interest of the Note Holders, or in the event that the Mortgagee shall have been requested to do so in writing by a Majority in Interest of Note Holders, the Mortgagee and, upon the written request of the Mortgagee, the Owner, shall execute and deliver an indenture supplemental hereto and all other instruments and agreements necessary or proper to remove any additional or separate trustee. The Mortgagee may act on behalf of the Owner under this Section 9.02(c) when and to the extent it could so act under Section 9.02(a) hereof.

Except as provided in Section A.2 below, Owner (or Permitted Lessee) will carry or cause to be carried at all times, at no expense to Mortgagee, commercial airline legal liability (including, but not limited to passenger liability, property damage, baggage liability, cargo and mail liability, hangarkeeper’s liability and contractual liability insurance) with respect to the Aircraft, the Airframe and the Engines, which is (i) in an amount not less than the greater of (x) the amount of commercial airline legal liability insurance from time to time applicable to aircraft owned or leased and operated by Owner (or Permitted Lessee) of the same type and operating on similar routes as the Aircraft and (y) the Minimum Liability Insurance Amount per occurrence; (ii) of the type and covering the same risks as from time to time applicable to aircraft operated by Owner (or Permitted Lessee) of the same type as the Aircraft; and (iii) maintained in effect with insurers of nationally or internationally recognized responsibility (such insurers being referred to herein as “Approved Insurers”). Owner (or Permitted Lessee) need not maintain cargo liability insurance with respect to the Aircraft, or may maintain such insurance in an amount less than the Minimum Liability Insurance Amount, as long as the amount of the cargo liability insurance, if any, maintained with respect to such Aircraft is not less than the amount of such coverage which is maintained by Owner (or Permitted Lessee) for other aircraft owned or leased by Owner (or Permitted Lessee) that are similar in type to such Aircraft and operated by Owner (or Permitted Lessee) on the same or similar routes.

2. During any period that the Aircraft is on the ground and not in operation, Owner (or Permitted Lessee) may carry or cause to be carried, in lieu of the insurance required by Section A.1 above, insurance otherwise conforming with the provisions of said Section A.1 except that (i) the amounts of coverage shall not be required to exceed the amounts of public liability and property damage insurance from time to time applicable to aircraft owned or operated by Owner (or Permitted Lessee) of the same type as the Aircraft which are on the ground and not in operation and (ii) the scope of the risks covered and the type of insurance shall be the same as from time to time shall be applicable to aircraft owned or operated by Owner (or Permitted Lessee) of the same type which are on the ground and not in operation.

In the case of a loss with respect to an engine (other than an Engine) installed on the Airframe, Mortgagee shall hold any payment to it of any insurance proceeds in respect of such loss for the account of Owner or any other third party that is entitled to receive such proceeds.

2. During any period that the Aircraft is on the ground and not in operation, Owner (or Permitted Lessee) may carry or cause to be carried, in lieu of the insurance required by Section B.1 above, insurance otherwise conforming with the provisions of said Section B.1 except that the scope of the risks and the type of insurance shall be the same as from time to time applicable to aircraft owned by Owner (or Permitted Lessee) of the same type similarly on the ground and not in operation, provided that Owner (or Permitted Lessee) shall maintain insurance against risk of loss or damage to the Aircraft in an amount equal to the Debt Balance during such period that the Aircraft is on the ground and not in operation.

C.	War-Risk, Hijacking and Allied Perils Insurance

If Owner (or any Permitted Lessee) shall at any time operate or propose to operate the Aircraft, Airframe or any Engine (i) in any area of recognized hostilities or (ii) on international routes and war-risk, hijacking or allied perils insurance is maintained by Owner (or any Permitted Lessee) with respect to other aircraft owned or operated by Owner (or any Permitted Lessee) on such routes or in such areas, Owner (or Permitted Lessee) shall maintain or cause to be maintained war-risk, hijacking and related perils insurance of substantially the same type carried by major United States commercial air carriers operating the same or comparable models of aircraft on similar routes or in such areas and in no event in an amount less than the unpaid Original Amount.

D.	General Provisions

Any policies of insurance carried in accordance with Sections A, B and C, including any policies taken out in substitution or replacement for such policies:

(ii) shall apply worldwide and have no territorial restrictions or limitations (except only in the case of war, hijacking and related perils insurance required under Section C, which shall apply to the fullest extent available in the international insurance market);

(iii) shall provide that, in respect of the interests of the Additional Insureds in such policies, the insurance shall not be invalidated or impaired by any act or omission (including misrepresentation and nondisclosure) by Owner (or any Permitted Lessee) or any other Person (including, without limitation, use for illegal purposes of the Aircraft or any Engine) and shall insure the Additional Insureds regardless of any breach or violation of any representation, warranty, declaration, term or condition contained in such policies by Owner (or any Permitted Lessee);

(iv) shall provide that, if the insurers cancel such insurance for any reason whatsoever, or if the same is allowed to lapse for nonpayment of premium, or if any material change is made in the insurance which adversely affects the interest of any of the Additional Insureds, such cancellation, lapse or change shall not be effective as to the Additional Insureds for thirty (30) days (seven (7) days in the case of war risk, hijacking and allied perils insurance and ten (10) days in case of nonpayment of premium) after receipt by the Additional Insureds of written notice by such insurers of such cancellation, lapse or change, provided that if any notice period specified above is not reasonably obtainable, such policies shall provide for as long a period of prior notice as shall then be reasonably obtainable;

(v) shall waive any rights of setoff (including for unpaid premiums), recoupment, counterclaim or other deduction, whether by attachment or otherwise, against each Additional Insured;

(vi) shall waive any right of subrogation against any Additional Insured;

(vii) shall be primary without right of contribution from any other insurance that may be available to any Additional Insured;

(viii) shall provide that all of the liability insurance provisions thereof, except the limits of liability, shall operate in all respects as if a separate policy had been issued covering each party insured thereunder;

(ix) shall provide that none of the Additional Insureds shall be liable for any insurance premium; and

On or prior to the Closing Date and on or prior to each renewal date of the insurance policies required hereunder, Owner(or Permitted Lessee) will furnish or cause to be furnished to Mortgagee insurance certificates describing in reasonable detail the insurance maintained by Owner (or Permitted Lessee) hereunder and a report, signed by Owner’s (or Permitted Lessee’s) regularly retained independent insurance broker (the “Insurance Broker”), stating the opinion of such Insurance Broker that (a) all premiums in connection with such insurance then due have been paid and (b) such insurance complies with the terms of this Annex B, except that such opinion shall not be required with respect to war risk insurance or indemnity provided by the U.S. Government. To the extent such agreement is reasonably obtainable Owner (or Permitted Lessee) will also cause the Insurance Broker to agree to advise Mortgagee in writing of any default in the payment of any premium and of any other act or omission on the part of Owner (or Permitted Lessee) of which it has knowledge and which might invalidate or render unenforceable, in whole or in part, any insurance on the Aircraft or Engines required hereunder or cause the cancellation or termination of such insurance, and to advise Mortgagee in writing at least thirty (30) days (seven (7) days in the case of war-risk and allied perils coverage and ten (10) days in the case of nonpayment of premium, or such shorter period as may be available in the international insurance market, as the case may be) prior to the cancellation, lapse or material adverse change of any insurance maintained pursuant to this Annex B.
