Facility minus Investment Earnings from such Downgrade Advance multiplied by (y) the fraction specified in the foregoing clause (i); (iii) (x) the amount equal to interest on any Non-Extension Advance (other than any Applied Non-Extension Advance) payable under Section 3.07 of each Liquidity Facility minus Investment Earnings from such Non-Extension Advance multiplied by (y) the fraction specified in the foregoing clause (i); (iv) (x) the amount equal to interest on any Special Termination Advance (other than any Applied Special Termination Advance) payable under Section 3.07 of each Liquidity Facility minus Investment Earnings from such Special Termination Advance multiplied by (y) the fraction specified in the foregoing clause (i); (v) if any payment default shall have occurred and be continuing with respect to interest on any “Series A Equipment Notes” or “Series B Equipment Notes” (each as defined in the Note Purchase Agreement), (x) the excess, if any, of (1) an amount equal to interest on any Unpaid Advance, Applied Downgrade Advance, Applied Non-Extension Advance or Applied Special Termination Advance payable under Section 3.07 of each Liquidity Facility over (2) the sum of Investment Earnings from any Final Advance plus any amount of interest at the Payment Due Rate actually payable (whether or not in fact paid) by the Owner on the overdue scheduled interest on the “Equipment Notes” (as defined in the Note Purchase Agreement) in respect of which such Unpaid Advance, Applied Downgrade Advance, Applied Non-Extension Advance or Applied Special Termination Advance was made by the Liquidity Provider multiplied by (y) a fraction the numerator of which shall be the then aggregate overdue amounts of interest on the Series A Equipment Notes and Series B Equipment Notes (other than interest becoming due and payable solely as a result of acceleration of any such Equipment Notes) and the denominator of which shall be the then aggregate overdue amounts of interest on all “Series A Equipment Notes” and “Series B Equipment Notes” (each as defined in the Note Purchase Agreement) (other than interest becoming due and payable solely as a result of acceleration of any such “Equipment Notes”); and (vi) any other amounts owed to the Liquidity Provider by the Subordination Agent as borrower under each Liquidity Facility other than amounts due as repayment of advances thereunder or as interest on such advances, except to the extent payable pursuant to clause (ii), (iii), (iv) or (v) above, multiplied by the fraction specified in the foregoing clause (i), (b) without duplication of any amounts paid or payable pursuant to the provisions hereof, Owner’s pro rata share of all compensation and reimbursement of expenses, disbursements and advances payable by the Owner under the Pass Through Trust Agreements, (c) without duplication of any amounts paid or payable pursuant to the provisions hereof, Owner’s pro rata share of all compensation and reimbursement of expenses and disbursements payable to the Subordination Agent under the Intercreditor Agreement except with respect to any income or franchise taxes incurred by the Subordination Agent in connection with the transactions contemplated by the Intercreditor Agreement and (d) in the event the Owner requests any amendment to any Operative Agreement or Pass Through Agreement, the Owner’s pro rata share of all reasonable fees and expenses (including, without limitation, fees and disbursements of counsel) of the Escrow Agents and the Paying Agents in connection therewith payable by the Pass Through Trustees under the Escrow Agreements. As used herein, “Owner’s pro rata share” means as of any time a fraction, the numerator of which is the principal balance then outstanding of Equipment Notes and the denominator of which is the aggregate principal balance then outstanding of all “Equipment Notes” (as each such term is defined in each of the Operative Indentures). For purposes of this paragraph, (i) the terms “Applied Downgrade Advance”, “Applied Non-Extension Advance”, “Applied Special Termination Advance”, “Downgrade Advance”, “Final Advance”, “Investment Earnings”, “Non-Extension Advance”,

“Special Termination Advance” and “Unpaid Advance” shall have the meanings specified in each Liquidity Facility and (ii) the term “Cash Collateral Account” shall have the meaning specified in the Intercreditor Agreement.

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

The aggregate Original Amount of any Series of Equipment Notes issued hereunder shall not exceed the amount set forth as the maximum therefor on Schedule I hereto.

SECTION 2.03. Method of Payment

(a) The Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due under each Equipment Note or hereunder will be payable in Dollars by wire transfer of immediately available funds not later than 12:30 p.m., New York time, on the due date of payment to the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee, 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 Indenture Trustee 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 Indenture Trustee for cancellation promptly after such payment. Notwithstanding any other provision of this Trust Indenture to the contrary, the Indenture Trustee 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 Indenture Trustee to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 12:30 p.m., New York time, at the place of payment. Prior to the due presentment for registration of transfer of any Equipment Note, the Owner and the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee consistent with this Section 2.03.

(b) The Indenture Trustee, 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 Indenture Trustee 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 Indenture Trustee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W-8BEN, W-8EXP or W-8IMY (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 any of the three preceding calendar years, and has not notified the Indenture Trustee of the withdrawal or inaccuracy of such form prior to the date of such payment (and the Indenture Trustee has no reason to believe that any information set forth in such form is inaccurate), the Indenture Trustee 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 Indenture Trustee

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) 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 any of the three preceding calendar years, and has not notified the Indenture Trustee of the withdrawal or inaccuracy of such certificate or form prior to the date of such payment (and the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 an applicable income tax convention, the Code or the regulations thereunder or the administrative interpretation of any of the foregoing 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 Indenture Trustee 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.

SECTION 2.04. 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 2.09, 2.10 and 2.11 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 maturity.

SECTION 2.05. Termination of Interest in Collateral

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 Indenture Trustee 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 2.06. Registration Transfer and Exchange of Equipment Notes

The Indenture Trustee shall keep a register (the “Equipment Note Register”) in which the Indenture Trustee 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 Indenture Trustee. The Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee at the Corporate Trust Office. Whenever any Equipment Notes are so surrendered for exchange, the Owner shall execute, and the Indenture Trustee 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 2.06 or under Section 2.07 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 Indenture Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Indenture Trustee duly executed by the Note Holder or such holder’s attorney duly authorized in writing, and the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee and such change is reflected on the Equipment Note Register. The Indenture Trustee 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 Indenture Trustee 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 2.06, the Indenture Trustee and the 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 2.07. 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee such security or indemnity as may be required by them to save the Owner and the Indenture Trustee harmless and evidence satisfactory to the Owner and the Indenture Trustee 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 the 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 2.07, the Indenture Trustee and the 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 2.08. 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 Indenture Trustee, 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 Indenture Trustee shall cancel all Equipment Notes surrendered for replacement, redemption, transfer, exchange, payment or cancellation and shall destroy the canceled Equipment Notes.

SECTION 2.09. 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 2.10. Optional Redemptions of Equipment Notes

SECTION 2.11. 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 Indenture Trustee.

(b) Notice of redemption with respect to the Equipment Notes shall be given by the Indenture Trustee by first-class mail, postage prepaid, mailed not less than twenty (20) nor more than sixty (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 the Indenture Trustee 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 Indenture Trustee, deposit or cause to be deposited with the Indenture Trustee by 12:30 p.m. New York time on the redemption date in immediately available funds the redemption price of the Equipment Notes to be redeemed.

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 2.12. Subordination

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 (in such capacity, the “Securities Intermediary”). WTNA waives any claim or lien against any Eligible Account it may have, by operation of law or otherwise, for any amount owed to it by the Owner. The Securities Intermediary hereby agrees that, notwithstanding anything to the contrary in this Trust Indenture, (i) any amounts to be held by the Securities Intermediary pursuant to paragraph (iv) of clause “Third” of Section 3.03 and any investment earnings thereon or other Cash Equivalents will be credited to an Eligible Account (the “Securities Account”) for which it is a “securities intermediary” (as defined in Section 8-102(a)(14) of the NY UCC) and the Indenture Trustee is the “entitlement holder” (as defined in Section 8-102(a)(7) of the NY UCC) of the “securities entitlement” (as defined in Section 8-102(a)(17) of the NY UCC) with respect to each “financial asset” (as defined in Section 8-102(a)(9) of the NY UCC) credited to such Eligible Account, (ii) all such amounts, Cash Equivalents and all other property acquired with cash credited to the Securities Account will be credited to the Securities Account, (iii) all items of property (whether cash, investment property, Cash Equivalents, other investments, securities, instruments or other property) credited to the Securities Account will be treated as a “financial asset” under Article 8 of the NY UCC, (iv) its “securities intermediary’s jurisdiction” (as defined in Section 8-110(e) of the NY UCC) with respect to the Securities Account is the State of New York, and (v) all securities, instruments and other property in order or registered from and credited to the Securities Account shall be payable to or to the order of, or registered in the name of, the Securities Intermediary or shall be indorsed to the Securities Intermediary or in blank, and in no case whatsoever shall any financial asset credited to the Securities Account be registered in the name of the Owner, payable

The Owner and the Securities Intermediary acknowledge that, by reason of the Indenture Trustee being the “entitlement holder” in respect of the Securities Account as provided above, the Indenture Trustee 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.

(ix) So long as no Event of Default shall have occurred and be continuing, 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) the Owner shall have furnished the Indenture Trustee with a favorable opinion of counsel, reasonably satisfactory to the Indenture Trustee, 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 the Indenture Trustee 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) the Indenture Trustee’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 the 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 or Permitted Lessee who receives possession by reason of a transfer permitted by any of clauses (i) through (ix) 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

Any Wet Lease or similar arrangement under which the Owner maintains operational control of the Aircraft shall not constitute a deliver, transfer or relinquishment of possession of the Aircraft for purposes of this Section.

The Indenture Trustee 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, the Owner or any Permitted Lessee subject to a lease, conditional sale, trust indenture or other security agreement that the Indenture Trustee, 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, medical emergency or other circumstances beyond the reasonable control of the Owner (or any Permitted Lessee), so long as the Owner (or any Permitted Lessee) diligently and in good faith proceeds to remove the Aircraft from such area. The Owner shall also have the right to operate the Aircraft without having on board the original registration certificate or airworthiness certificate in the event that either or both such certificates disappear from the Aircraft, but only to the extent permitted by Exemption No. 5318 of the FAA Regulations or other similar exemption. 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 of any Government Entity having jurisdiction over the Aircraft that is 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 the 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 the 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 the Indenture Trustee or impair the Indenture Trustee’s security interest or International Interest in the Aircraft, Airframe or any Engine. Owner shall not be in default under or required to take any action set forth in the preceding sentence if it is not possible for Owner to comply with the laws of a jurisdiction other than the United States (or other jurisdiction in which the Aircraft is registered) because of a conflict with the Laws of the United States (or other jurisdiction in which the Aircraft is registered).

(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 Owner’s FAA approved maintenance program or while registered in another jurisdiction, under the applicable maintenance standards required by the Aviation Authority in such jurisdiction

(provided, that in any case, if operated under the maintenance program of an Aviation Authority other the FAA, the Aircraft, Airframe and each Engine shall be maintained according to standards substantially equivalent to those required by the Aviation Authority of any of Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland or the United Kingdom) 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 (w) during temporary periods of storage in accordance with applicable regulations, (x) maintenance, testing and modification permitted hereunder, (y) during periods when the FAA or such other Aviation Authority has revoked or suspended the airworthiness certificates for Similar Aircraft or (z) with respect to minor or nonrecurring violations with respect to which corrective measures are taken upon discovery thereof and except to the extent the Owner or Permitted Lessee is promptly 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 the Indenture Trustee therein or any material risk of criminal liability or material civil penalty against the Indenture Trustee; and (ii) except during periods when a Permitted Lease is in effect, the same standards as the Owner uses with respect to similar aircraft of similar size in its fleet operated by the 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 the Owner’s obligations under the preceding clause (i)). The Owner further agrees that the Aircraft, Airframe and Engines will be maintained, used, serviced, repaired, overhauled or inspected in compliance with each applicable airworthiness certificate, license and registration relating to the Aircraft, Airframe or any Engine issued by the FAA (or other applicable Aviation Authority). 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, the Owner may, by written notice to the Indenture Trustee, 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 the Trust Indenture has been discharged, the Owner shall also cause the 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 the Indenture Trustee to execute and deliver any necessary documents). Unless the Lien of this Indenture has been discharged, the Owner shall cause the International Interest granted under this Indenture in favor of the Indenture Trustee in each Airframe and Engine to be registered on the International Registry as an International Interest on such Airframe and Engine, subject to the Indenture Trustee providing its consent to the International

Registry with respect thereto[, and shall cause the sale to the Owner of the Airframe and each Engine at the Closing to be registered on the International Registry]⁹.

(f) Markings. If permitted by applicable Law, on or reasonably promptly after the Closing Date, the 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 Company, not in its individual capacity but solely as Indenture Trustee.” 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, the Owner shall promptly replace it with a placard complying with the requirements of this Section.

SECTION 4.03. Inspection

(a) At all reasonable times upon at least 15 Business Days prior written notice to Owner, so long as the Aircraft is subject to the Lien of this Trust Indenture, the Indenture Trustee and its authorized representatives (the “Inspecting Parties”) may (not more than once every twelve (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 the 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 the like or other components of the Aircraft, and no such inspection shall interfere with the Owner’s or any Permitted Lessee’s maintenance and operation of the Aircraft, Airframe and Engines. Any inspection shall be subject to the Owner’s safety and security rules applicable to the location of the Aircraft.

(c) With respect to such rights of inspection, the Indenture Trustee 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 of Engines

(a) Replacement of Parts. Except as otherwise provided herein, so long as the Airframe or Engine is subject to the Lien of this Trust Indenture, the 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, except as otherwise provided in paragraph (d) of this Section 4.04 or if the Airframe or Engine to which a Part relates has suffered an Event of Loss. In addition, the 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 the 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 Indenture Trustee 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. Upon request of Owner, the Indenture Trustee shall, at Owner’s expense, execute and deliver to Owner such documents as may be reasonably required to evidence the release of any replaced Part from the Lien of the Indenture.

(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 the 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”); except for (i) immaterial and non-recurring violations with respect to which corrective measures are being taken promptly by Owner or a Permitted Lessee and (ii) any law, rule, regulation or order the validity or application of which is being contested in good faith by the Owner or any Permitted Lessee in any reasonable manner which does not materially adversely affect the Indenture Trustee’s interest in the Aircraft, does not impair the Indenture Trustee’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 the Indenture Trustee therein or any material risk of material civil penalty or any material risk of criminal liability being imposed on the Indenture Trustee 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 the 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. For the avoidance of doubt, Owner may make alterations in the passenger configuration of the Aircraft and such alterations shall not constitute an Optional Modification. 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 Indenture Trustee and such Part shall no longer be deemed a Part hereunder. Removable Parts may be leased from or financed by third parties other than the Indenture Trustee. Notwithstanding any other provision of this Indenture, Owner may, at any time, install or permit to be installed in the Aircraft Passenger Convenience Equipment owned by Owner or any Permitted Lessee or by third parties and leased or otherwise furnished to Owner in the ordinary course of business (including pursuant to a conditional sale contract, a licence or otherwise), and Owner may remove (and not replace) or permit to be removed (and not replaced) the same, and Indenture Trustee shall not acquire a Lien thereon by virtue of such installation or otherwise, and the rights of the owners therein shall not constitute a default under this Trust Indenture, it being acknowledged and agreed, however, that in no event shall the installation of any such Passenger Convenience Equipment impair or otherwise affect the rights and remedies of the Indenture Trustee hereunder and under applicable law.

(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, the Owner shall promptly (and in any event within fifteen (15) days after such occurrence) give the Indenture Trustee written notice of such Event of Loss. The Owner shall have the right at its option at any time, on at least five (5) Business Days’ prior notice to the Indenture Trustee, 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 one hundred and twenty (120) 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee:

(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 ▇▇▇▇ 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 Indenture Trustee); 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 Indenture Trustee to protect the security interests of the Indenture Trustee in the Replacement Engine;

(ii) the Owner shall cause to be delivered to the Indenture Trustee 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 the Indenture Trustee shall reasonably request;

(iii) promptly after the filing of the Trust Indenture Supplement, the Owner shall have caused to be furnished to the Indenture Trustee an opinion of the Owner’s aviation law counsel reasonably satisfactory to the Indenture Trustee addressed to the Indenture Trustee 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 the Owner shall have caused to be effected) with the International Registry of the sale to the 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 the Indenture Trustee a certificate of a qualified aircraft engineer (who may be an employee of the Owner) or an independent appraiser 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 Indenture Trustee 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 Indenture Trustee 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

(ii) if the Owner elects to make a payment in respect of such Event of Loss of the Airframe, the Owner shall make a payment to the Indenture Trustee for purposes of redeeming Equipment Notes in accordance with Section 2.09 hereof on a date on or before the Business Day next following the earlier of (x) the one hundred and twentieth (120)th day following the date of the occurrence of such Event of Loss, and (y) the fourth (4^th) 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 the 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee shall assign to the Owner all claims the Indenture Trustee 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:

(i) on the date when the Replacement Airframe and Replacement Engines, if any, is subjected to the Lien of this Trust Indenture (such date being referred to in this Section 4.05 as the “Replacement Closing Date”), an executed counterpart of each of the following documents (or, in the case of the FAA ▇▇▇▇ of Sale and full warranty ▇▇▇▇ of sale referred to below, a photocopy thereof) shall have been delivered to the Indenture Trustee:

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

(d) Non-Insurance Payments Received on Account of an Event of Loss. Any amounts, other than insurance proceeds in respect of damage or loss not constituting an Event of Loss (the application of which is provided for in Annex B), received at any time by the Indenture Trustee or the Owner from any Government Entity or any other Person in respect of any Event of Loss will be applied as follows:

(i) If such amounts are received with respect to the Airframe, and any Engine installed thereon at the time of such Event of Loss, upon compliance by the Owner with the applicable terms of Section 4.05(c) with respect to the Event of Loss for which such amounts are received, such amounts shall be paid over to, or retained by, the Owner;

(ii) If such amounts are received with respect to an Engine (other than an Engine installed on the Airframe at the time such Airframe suffers an Event of Loss), upon compliance by the Owner with the applicable terms of Section 4.04(e) with respect to the Event of Loss for which such amounts are received, such amounts shall be paid over to, or retained by, the Owner;

(iii) If such amounts are received, in whole or in part, with respect to the Airframe, and the Owner makes, has made or is deemed to have made the election set forth in Section 4.05(a)(ii), such amounts shall be applied as follows:

first, if the sum described in Section 4.05(a)(ii) has not then been paid in full by the Owner, such amounts shall be paid to the Indenture Trustee to the extent necessary to pay in full such sum; and

(e) Requisition for Use. In the event of a requisition for use by any Government Entity of the Airframe and the Engines, if any, or engines installed on such Airframe while such Airframe is subject to the Lien of this Trust Indenture, the Owner shall promptly notify the Indenture Trustee of such requisition and all of the Owner’s obligations under this Trust Indenture shall continue to the same extent as if such requisition had not occurred except to the extent that the performance or observance of any obligation by the Owner shall have been prevented or delayed by such requisition; provided that the Owner’s obligations under this Section 4.05 with respect to the occurrence of an Event of Loss for the payment of

money and under Section 4.06 (except while an assumption of liability by the U.S. Government of the scope referred to in Section 4.02(c) is in effect) shall not be reduced or delayed by such requisition. Any payments received by the Indenture Trustee or the Owner or Permitted Lessee from such Government Entity with respect to such requisition of use shall be paid over to, or retained by, the Owner. In the event of an Event of Loss of an Engine resulting from the requisition for use by a Government Entity of such Engine (but not the Airframe), the Owner will replace such Engine hereunder by complying with the terms of Section 4.04(e) and any payments received by the Indenture Trustee or the Owner from such Government Entity with respect to such requisition shall be paid over to, or retained by, the Owner.

(f) Certain Payments to be Held As Security.

SECTION 4.06. Insurance

(a) Owner’s Obligation to Insure. The 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) Indenture Trustee 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 the Owner pursuant to this Section 4.06 and Annex B.

(c) Indemnification by Government in Lieu of Insurance. The Indenture Trustee 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 the Indenture Trustee, 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 the 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.

(d) Application of Insurance Proceeds. As between the Owner and the Indenture Trustee, all insurance proceeds received as a result of the occurrence of an Event of Loss with respect to the Aircraft or any Engine under policies required to be maintained by the

Owner pursuant to this Section 4.06 will be applied in accordance with Section 4.05(d). All proceeds of insurance required to be maintained by the 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, the Owner.

SECTION 4.07. Merger of Owner

(a) In General. The 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 the Indenture Trustee a duly authorized, legal, valid, binding and enforceable agreement, reasonably satisfactory in form and substance to the Indenture Trustee, 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 the 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 and, irrespective of the registry of the Aircraft, such person makes such registrations with the International Registry, in any case, as shall be necessary to evidence such consolidation or merger; and

(iv) 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 the Owner with or into, or the conveyance, transfer or lease by the 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, the 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 the Owner under this Trust Indenture.

(iv) any representation or warranty made by the Owner herein, in the Participation Agreement or in any other Operative Agreement to which Owner is a party (a) shall prove to have been untrue or inaccurate in any material respect as of the date made, (b) such untrue or inaccurate representation or warranty is material at the time in question, (c) and the same shall remain uncured (to the extent of the adverse impact of such incorrectness on the interest of the Indenture Trustee) for a period in excess of thirty (30) days from and after the date of written notice thereof from the Indenture Trustee to the Owner;

(v) the Owner shall consent to the appointment of or taking possession by a receiver, trustee or liquidator of itself or of a substantial part of its property, or the Owner shall admit in writing its inability to pay its debts generally as they come due or shall make a general assignment for the benefit of its creditors, or the Owner shall file a voluntary petition in bankruptcy or a voluntary petition or an answer seeking reorganization, liquidation or other relief under any bankruptcy laws or insolvency laws (as in effect at such time), or an answer admitting the material allegations of a petition filed against it in any such case, or the

(viii) the occurrence of a Related Indenture Event of Default.

provided, however, that, notwithstanding anything to the contrary contained in this Section 5.01, any failure of Owner to perform or observe any covenant, condition, agreement or any error in a representation or warranty shall not constitute an Event of Default if such failure or error is caused solely by reason of any event that constitutes an Event of Loss so long as Owner is continuing to comply with all of the terms of Section 4.04(e) and Section 4.05 hereof.

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 Indenture Trustee 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 Indenture Trustee shall give the Owner twenty (20) days’ prior written notice of its intention to sell the Aircraft; provided further, that during any period the Aircraft is subject to the CRAF program and in possession of the U.S. Government or an agency or instrumentality of the United States, the Indenture Trustee shall not, on account of any Event of Default, be entitled to exercise or pursue any of the powers, rights or remedies described in this Article V in such manner as to limit the Owner’s control (or any Permitted

Lessee’s control under any lease) of any Airframe or any Engines installed thereon, unless at least sixty (60) days (or such lesser period as may then be applicable under the Air Mobility Command program of the U.S. Government) written notice of default hereunder shall have been given by the Indenture Trustee by registered or certified mail to the Owner (any Permitted Lessee) with a copy addressed to the Contracting Office Representative of the Air Mobility Command of the United States Air Force under any contract with the Owner (or any Permitted Lessee) relating to the Aircraft. Without limiting any of the foregoing, it is understood and agreed that the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee, rescind and annul the Indenture Trustee’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 Indenture Trustee 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 Indenture Trustee, the Owner shall promptly execute and deliver to the Indenture Trustee such instruments of title and other documents as the Indenture Trustee may deem necessary or advisable to enable the Indenture Trustee or an agent or representative designated by the Indenture Trustee, at such time or times and place or places as the Indenture Trustee may specify, to obtain possession of all or any part of the Collateral to which the Indenture Trustee 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 Indenture Trustee, the Indenture Trustee may (i) obtain a judgment conferring on the Indenture Trustee the right to immediate possession and requiring the Owner to execute and deliver such instruments and documents to the Indenture Trustee, 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 the 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee may determine, and the Indenture Trustee 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 Indenture Trustee under any provision of this Trust Indenture to collect and receive all cash held by, or required to be deposited with, the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee, and of all persons properly engaged and employed by the Indenture Trustee with respect hereto.

SECTION 5.04. Remedies Cumulative

Each and every right, power and remedy given to the Indenture Trustee 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 Indenture Trustee, 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee, then and in every such case the Owner and the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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

If an Event of Default shall have occurred and be continuing, the Indenture Trustee shall, as a matter of right, be entitled to the appointment of a receiver (who may be the Indenture Trustee 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 Indenture Trustee with respect to the Collateral.

SECTION 5.08. Indenture Trustee Authorized to Execute Bills of Sale, Etc.

The Owner irrevocably appoints, while an Event of Default has occurred and is continuing, the Indenture Trustee 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 Indenture Trustee or any purchaser, the Owner shall ratify and confirm any such sale, assignment, transfer or delivery, by executing and delivering to the Indenture Trustee 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 INDENTURE TRUSTEE

SECTION 6.01. Notice of Event of Default

If the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee shall be instructed in writing by a Majority in Interest of Note Holders. Subject to the

provisions of Section 6.03, if the Indenture Trustee shall not have received instructions as above provided within 20 days after mailing notice of such Event of Default to the Note Holders, the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee, the Indenture Trustee shall not be deemed to have knowledge of a Default or an Event of Default (except, the failure of the 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 Indenture Trustee 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 Indenture Trustee shall not, except as provided in Section 6.01, approve any such matter as satisfactory to the Indenture Trustee.

The Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee hereunder.

SECTION 6.03. Indemnification

The Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee shall be accepted as reasonable assurance of adequate indemnity). The Indenture Trustee 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 Indenture Trustee to take any action, if the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee. The Indenture Trustee 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 Indenture Trustee will not use, operate, store, lease, control, manage, sell, dispose of or otherwise deal with the Aircraft or any other part of the Collateral except in accordance with the powers granted to, or the authority conferred upon the Indenture Trustee pursuant to this Trust Indenture and in accordance with the express terms hereof.

SECTION 6.06. Investment of Amounts Held by Indenture Trustee

Any amounts held by the Indenture Trustee or the Securities Intermediary pursuant to Section 3.02, 3.03 or 3.07 or pursuant to any provision of any other Operative Agreement providing for amounts to be held by the Indenture Trustee or the Securities Intermediary which are not distributed pursuant to the other provisions of Article III hereof shall be invested by the Indenture Trustee or the Securities Intermediary, as applicable, from time to time in Cash Equivalents as directed by the Owner so long as the Indenture Trustee or the Securities Intermediary, as applicable, may acquire the same using its best efforts. All Cash Equivalents held by the Indenture Trustee or the Securities Intermediary pursuant to this Section 6.06 shall either be (a) registered in the name of, payable to the order of, or specially endorsed to,

the Indenture Trustee, or (b) held in an Eligible Account. Unless otherwise expressly provided in this Trust Indenture, any income realized as a result of any such investment, net of the Indenture Trustee’s and the Securities Intermediary’s reasonable fees and expenses in making such investment, shall be held and applied by the Indenture Trustee or the Securities Intermediary, as applicable, in the same manner as the principal amount of such investment is to be applied and any losses, net of earnings and such reasonable fees and expenses, shall be charged against the principal amount invested. Neither the Indenture Trustee nor the Securities Intermediary shall 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 Indenture Trustee or the Securities Intermediary, as applicable, without instructions whenever such sale is necessary to make a distribution required by this Trust Indenture.

THE INDENTURE TRUSTEE IN ITS INDIVIDUAL OR TRUST CAPACITY DOES NOT MAKE AND SHALL NOT BE DEEMED TO HAVE MADE AND HEREBY EXPRESSLY DISCLAIMS ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO THE TITLE, AIRWORTHINESS, VALUE, COMPLIANCE WITH SPECIFICATIONS, CONDITION, DESIGN, QUALITY, DURABILITY, OPERATION, MERCHANTABILITY OR FITNESS FOR USE FOR A PARTICULAR PURPOSE OF THE AIRCRAFT OR ANY ENGINE, AS TO THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE, AS TO THE ABSENCE OF ANY INFRINGEMENT OF ANY PATENT, TRADEMARK OR COPYRIGHT, AS TO THE ABSENCE OF OBLIGATIONS BASED ON STRICT LIABILITY IN TORT OR ANY OTHER REPRESENTATION OR WARRANTY WHATSOEVER.

SECTION 7.05. Reliance; Agreements; Advice of Counsel

The Indenture Trustee shall not incur any liability to anyone in acting upon any signature, instrument, notice, resolution, request, consent, order, certificate, report, opinion, bond or other document or paper believed by it to be genuine and believed by it to be signed by the proper party or parties. The Indenture Trustee may accept a copy of a resolution of the Board of Directors of the Owner, certified by the Secretary or an Assistant Secretary thereof as duly adopted and in full force and effect, as conclusive evidence that such resolution has been duly adopted and that the same is in full force and effect. As to the aggregate unpaid Original Amount of Equipment Notes outstanding as of any date, the Owner may for all purposes hereof rely on a certificate signed by any Vice President or other authorized corporate trust officer of

the Indenture Trustee. As to any fact or matter relating to the Owner the manner of the ascertainment of which is not specifically described herein, the Indenture Trustee may for all purposes hereof rely on a certificate, signed by a duly authorized officer of the Owner, as to such fact or matter, and such certificate shall constitute full protection to the Indenture Trustee for any action taken or omitted to be taken by it in good faith in reliance thereon. In the administration of the trusts hereunder, the Indenture Trustee may execute any of the trusts or powers hereof and perform its powers and duties hereunder directly or through agents or attorneys and may, at the expense of the Collateral, advise with counsel, accountants and other skilled persons to be selected and retained by it, and the Indenture Trustee shall not be liable for anything done, suffered or omitted in good faith by it in accordance with the written advice or written opinion of any such counsel, accountants or other skilled persons.

In the administration of the trusts created hereunder, the Indenture Trustee shall have the right to seek instructions from a Majority in Interest of Note Holders should any provision of this Trust Indenture appear to conflict with any other provision herein or should the Indenture Trustee’s duties or obligations hereunder be unclear, and the Indenture Trustee shall incur no liability in refraining from acting until it receives such instructions.

ARTICLE VIII

SUCCESSOR SECURITIES INTERMEDIARY

SECTION 8.01. Resignation of Securities Intermediary; Appointment of Successor

(a) The Securities Intermediary or any successor thereto may resign at any time without cause by giving at least thirty (30) days’ prior written notice to the Owner and the Indenture Trustee, such resignation to be effective upon the acceptance of the Securities Intermediary’s obligations under this Trust Indenture by a successor Securities Intermediary. 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 Securities Intermediary without cause

by an instrument in writing delivered to the Owner and the Indenture Trustee, and the Indenture Trustee shall promptly notify each Note Holder thereof in writing, such removal to be effective upon the acceptance of the Securities Intermediary’s obligations under this Trust Indenture by a successor Securities Intermediary. In the case of the resignation or removal of the Securities Intermediary, so long as no Event of Default shall have occurred and be continuing, the Owner may appoint a successor Securities Intermediary or, if an Event of Default shall have occurred and be continuing, a Majority in Interest of Note Holders may appoint a successor Securities Intermediary, in each case by an instrument signed by the Owner or such holders, whichever shall have made such appointment. If a successor Securities Intermediary shall not have been appointed within thirty (30) days after such notice of resignation or removal, the Securities Intermediary, the Owner or any Note Holder may apply to any court of competent jurisdiction to appoint a successor Securities Intermediary to act until such time, if any, as a successor shall have been appointed as above provided.

(a) The Indenture Trustee or any successor thereto may resign at any time without cause by giving at least thirty (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 Indenture Trustee. In addition, a Majority in Interest of Note Holders may at any time (but only with the consent of the 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 Indenture Trustee without cause by an instrument in writing delivered to the Owner and the Indenture Trustee, and the Indenture Trustee shall promptly notify each Note Holder thereof in writing, such removal to be effective upon the acceptance of the trusteeship by a successor Indenture Trustee. In the case of the resignation or removal of the Indenture Trustee, a Majority in Interest of Note Holders may appoint a successor Indenture Trustee 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 the Owner’s reasonable approval. If a successor Indenture Trustee shall not have been appointed within thirty (30) days after such notice of resignation or removal, the Indenture Trustee, the Owner or any Note Holder may apply to any court of competent jurisdiction to appoint a successor Indenture Trustee to act until such time, if any, as a successor shall have been appointed as above provided. The successor Indenture Trustee so appointed by such court shall immediately and without further act be superseded by any successor Indenture Trustee appointed as above provided.

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

(c) No successor Indenture Trustee may be appointed in any manner unless it is 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 with (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 Indenture Trustee hereunder upon reasonable or customary terms.

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

(e) The Owner consents to any change in the identity of the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee shall be advised by counsel satisfactory to it that it is so necessary or prudent in the interests of the Note Holders (and the Indenture Trustee shall so advise the Owner), or (iii) the Indenture Trustee shall have been requested to do so by a Majority in Interest of Note Holders, then in any such case, the Indenture Trustee and, upon the written request of the Indenture Trustee, 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 Indenture Trustee, either to act jointly with the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee so to do, or if an Event of Default shall have occurred and be continuing, the Indenture Trustee 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 Indenture Trustee, 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee shall be promptly paid over by it to the Indenture Trustee. All other rights, powers, duties and obligations conferred or imposed upon any additional or separate trustee shall be exercised or performed by the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee shall be liable for the consequences of its lack of reasonable care in selecting, and the Indenture Trustee’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 Indenture Trustee. The powers of any additional or separate trustee appointed pursuant to this Section 9.02 shall not in any case exceed those of the Indenture Trustee hereunder.

(c) If at any time the Indenture Trustee shall deem it no longer necessary or in order to conform to any such Law or take any such action or shall be advised by such counsel that it is no longer so necessary or desirable in the interest of the Note Holders, or in the event that the Indenture Trustee shall have been requested to do so in writing by a Majority in Interest of Note Holders, the Indenture Trustee and, upon the written request of the Indenture Trustee, 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 Indenture Trustee 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.

The Additional Insureds shall have the rights but not the obligations of an additional named insured. None of the Indenture Trustee and the other Additional Insured shall have any obligation to pay any premium, commission, assessment or call due on any such insurance (including reinsurance).

G.	Deductibles; Self-insurance

The Owner may self-insure by way of deductible, premium adjustment or franchise provisions or otherwise (including, with respect to insurance maintained pursuant to Section B, insuring for a maximum amount which is less than the Debt Balance) in the insurance covering the risks required to be insured against pursuant to Section 4.06 and this Annex B under a program applicable to all aircraft in the Owner’s fleet, but in no case shall the aggregate amount of self-insurance in regard to Section 11 and this Annex B exceed during any policy year, with respect to all of the aircraft in the Owner’s fleet (including, without limitation, the Aircraft), the lesser of (a) 50% of the largest replacement value of any single aircraft in the Owner’s fleet and (b) 1-1/2% of the average aggregate insurable value (during the preceding policy year) of all aircraft (including, without limitation, the Aircraft) on which the Owner carries insurance, unless an insurance broker of national standing shall certify that the standard among all other major U.S. airlines is a higher level of self-insurance, in which case the Owner may self-insure to such higher level. In addition, the Owner (and any Permitted Lessee) may self-insure to the extent of any applicable deductible per aircraft that does not exceed industry standards for major U.S. airlines.
