The Owner Trustee agrees to pay to the Indenture Trustee for distribution in accordance with Section 3.04 hereof (a) any and all indemnity amounts received by the Owner Trustee which are payable by Lessee to (i) the Indenture Trustee in its individual capacity, (ii) the Pass Through Trusts, (iii) the Subordination Agent, (iv) the Liquidity Providers, or (v) the Pass Through Trustees, in each case pursuant to Sections 10 and 13 of the Lease or Section 21 of the Refunding Agreement, (b) any and all amounts received by the Owner Trustee which are payable by Lessee in respect of and equal to the Owner Trustee's pro rata share (as defined below) of all amounts owed to the Liquidity Providers by the Subordination Agent under each Liquidity Facility (as determined by the Subordination Agent in consultation with the Liquidity Providers and notified to the Indenture Trustee) other than amounts due as (i) repayments of the principal of advances thereunder, and (ii) interest on Interest Drawings, Final Drawings and Applied Downgrade Drawings under any Liquidity Facility except to the extent included in Net Interest and Related Charges (as defined below), and (c) any and all amounts received by the Owner Trustee which are payable by Lessee under clause (vii) or (viii) of the definition of Supplemental Rent. The Indenture Trustee shall have no duty or obligation to (i) verify or confirm the accuracy of any of the amounts (other than the portion of the Principal Amount of, and interest on, the Equipment Notes issued hereunder) paid to it by the Owner Trustee or (ii) determine whether any amounts are owed by the Owner Trustee under this Section 2.02. As used in this Section 2.02, "Owner Trustee's pro rata share" means as of any time: (A) with respect to all amounts other than Net Interest and Related Charges, a fraction the numerator of which is the aggregate principal balance then outstanding of the Equipment Notes issued hereunder and the denominator of which is the aggregate principal balance then outstanding of all "Equipment Notes" issued under the Indentures, and Trust Indenture 33 - 28 - (B) with respect to all Net Interest and Related Charges (x) if there exists a Payment Default (as defined below) under any Equipment Note a fraction, the numerator of which is the aggregate principal balance then outstanding of the Equipment Notes issued hereunder and the denominator of which is the aggregate principal balance then outstanding of all "Equipment Notes" issued under the Indentures under which there exists a Payment Default or (y) at all other times, zero; provided, however, neither the numerator nor the denominator of the fractions in paragraphs (A) or (B) shall include any "Series D Equipment Notes" or "Series E Equipment Notes" issued under the Indentures. As used in this Section 2.02, "Net Interest and Related Charges" means (as determined by the Subordination Agent in consultation with the Liquidity Providers and notified to the Indenture Trustee except that the Past Due Rate shall be determined by the Indenture Trustee and notified to the Subordination Agent) the sum of (i) the amount, if any, by which interest payable to any Liquidity Provider on any Interest Drawing, Final Drawing and/or Downgrade Drawing (other than a Downgrade Drawing that is not an Applied Downgrade Drawing (as defined in the Liquidity Facilities)) exceeds the amount which would be payable if such advances bore interest at the Designated Interest Rate (as defined below) plus (ii) any amounts payable under Section 3.1, Section 3.2, Section 3.3, Section 3.9 or Section 7.7 of each Liquidity Facility (or similar provisions of any succeeding liquidity facility) which result from any Interest Drawing, Final Drawing or Downgrade Drawing. As used in this Section 2.02, "Designated Interest Rate" means the weighted average Past Due Rate (as defined in the applicable Indentures) in respect of "Series A Equipment Notes," "Series B Equipment Notes" and "Series C Equipment Notes" issued under the Indentures, except with respect to that portion of any Final Drawing (or Downgrade Drawing which becomes a Final Drawing) which remains in a Cash Collateral Account, Designated Interest Rate means the weighted average Investment Earnings of funds in the Cash Collateral Accounts. As used in this Section 2.02, a "Payment Default" when used in connection with an "Equipment Note" issued under an Indenture means a default in the payment of principal thereof or interest thereon, other than a default in the payment of principal or interest on a "Series D Equipment Note" or "Series E Equipment Note" issued under the Indentures which has not been cured other than solely because of acceleration. For purposes of Section 3.04(b) hereof, this is the fourth paragraph of Section 2.02. The Equipment Notes shall be executed on behalf of the Owner Trustee by its President or one of its Vice Presidents, Assistant Vice Presidents or Assistant Secretaries or other authorized officer. Equipment Notes bearing the signatures of Trust Indenture 34 - 29 - individuals who were at any time the proper officers of the Owner Trustee shall bind the Owner Trustee, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Equipment Notes or did not hold such offices at the respective dates of such Equipment Notes. The Owner Trustee may from time to time execute and deliver Equipment Notes with respect to the Engine 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 Trustee signed by a Vice President or Assistant Vice President or other authorized officer of the Owner Trustee; provided, however, that each such request shall specify the aggregate Principal Amount of all Equipment Notes to be authenticated hereunder on original issue with respect to the Engine. No Equipment Note shall be secured by or be entitled to any benefit under this 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 shall be conclusive evidence, and the only evidence, that such Equipment Note has been duly authenticated and delivered hereunder. SECTION 2.03. Payments from Trust Indenture Estate Only. (a) Without impairing any of the other rights, powers, remedies, privileges or Liens of the Note Holders under this Indenture, each Note Holder, by its acceptance of an Equipment Note, agrees that, except as expressly provided in this Indenture, the Refunding Agreement or any other Operative Document, (i) the obligation to make all payments of all or any portion of the Principal Amount of, interest on, Make-Whole Amount, if any, and all other amounts due with respect to the Equipment Notes, and the performance by the Owner Trustee of every obligation or covenant contained in this Indenture and in the Refunding Agreement or any of the other Operative Documents, shall be payable only from the income and proceeds from the Trust Estate to the extent included in the Trust Indenture Estate and only to the extent that the Owner Trustee shall have sufficient income or proceeds from the Trust Estate to the extent included in the Trust Indenture Estate to enable the Indenture Trustee to make such payments in accordance with the terms of Article III hereof, and all of the statements, representations, covenants and agreements made by the Owner Trustee (when made in such capacity) contained in this Indenture and any other Operative Document other than the Trust Agreement, unless expressly otherwise stated, are made and intended only for the purpose of binding the Trust Estate and establishing the existence of rights and remedies which can be exercised and enforced against the Trust Estate; therefore, anything contained in this Indenture or such Trust Indenture 35 - 30 - other agreements to the contrary notwithstanding (except for any express provisions or representations that the Trust Company is responsible for, or is making, for which there would be personal liability of the Trust Company), no recourse shall be had with respect to this Indenture or such other agreements against the Trust Company or against any institution or Person which becomes a successor trustee or co-trustee or any officer, director, trustee, servant or direct or indirect parent or controlling Person or Persons of any of them, and (ii) none of the Trust Company, the Owner Participant, the Indenture Trustee and any officer, director, trustee, servant, employee, agent or direct or indirect parent or controlling Person or Persons of any of them shall have any personal liability for any amounts payable, or other obligation owed, hereunder, under the Refunding Agreement or any of the other Operative Documents or under the Equipment Notes except as expressly provided herein (in the case of the Owner Trustee and the Indenture Trustee) or therein; provided, however, nothing contained in this Section 2.03(a) shall be construed to limit the exercise and enforcement in accordance with the terms of this Indenture or such other agreements of rights and remedies against the Trust Indenture Estate. (b) If (i) all or any part of the Trust Estate becomes the property of, or the Owner Trustee or Owner Participant becomes, a debtor subject to the reorganization provisions of the Bankruptcy Code, (ii) pursuant to such reorganization provisions, including Section 1111(b) of the Bankruptcy Code, the Trust Company, the Owner Trustee or the Owner Participant is required, by reason of the Trust Company, the Owner Trustee or the Owner Participant being held to have recourse liability to any Note Holder or the Indenture Trustee, directly or indirectly (other than the recourse liability of the Trust Company, the Owner Trustee or the Owner Participant under the Operative Documents), to make payment on account of any amount payable as Principal Amount, Make-Whole Amount, if any, interest or other amounts on the Equipment Notes or under this Indenture and (iii) any Note Holder or the Indenture Trustee actually receives any Excess Amount (as hereinafter defined) which reflects any payment by the Trust Company, the Owner Trustee or the Owner Participant on account of clause (ii) above (other than aforesaid), then such Note Holder or the Indenture Trustee, as the case may be, shall promptly refund to the Trust Company, the Owner Trustee or the Owner Participant (whichever shall have made such payment) such Excess Amount. For purposes of this Section 2.03(b), "Excess Amount" means the amount by which such payment exceeds the amount that would have been received by a Note Holder or the Indenture Trustee if the Trust Company, the Owner Trustee or the Owner Participant had not become subject to the recourse liability referred to in clause (ii) above. Nothing contained in this Trust Indenture 36 - 31 - Section 2.03(b) shall prevent a Note Holder or the Indenture Trustee from enforcing any personal recourse obligation (and retaining the proceeds thereof) of the Trust Company, the Owner Trustee or the Owner Participant under the Refunding Agreement, this Indenture (and any exhibits or annexes hereto or thereto) or any other Operative Document. SECTION 2.04. Method of Payment. (a) The Principal 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 12:00 noon, New York City 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. After transferring (or causing the transfer of) the above amounts to the Indenture Trustee, the Owner Trustee shall not have any responsibility for the distribution of such payment to any Note Holder. Notwithstanding the foregoing or any provision in any Equipment Note to the contrary, the 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 Trustee), all amounts paid by the Owner Trustee hereunder and under such Holder's Equipment Note or Equipment Notes to such Holder or a nominee therefor (including all amounts distributed pursuant to Article III of this 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 preceding 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 and without indemnification or right of reimbursement under any Operative Document, agrees to compensate such Holders for loss of use of funds in accordance with industry standards for this type of transaction 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 free and clear of and without reduction for or on account of all wire and like charges and 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 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 if such Trust Indenture 37 - 32 - funds were received after 12:00 noon, New York City time, at the place of payment. Prior to the due presentment for registration of transfer of any Equipment Note, the Owner Trustee and the Indenture Trustee shall deem and treat the Person in whose name any Equipment Note is registered on the Register as the absolute owner and Holder of such Equipment Note for the purpose of receiving payment of all amounts payable with respect to such Equipment Note and for all other purposes, and neither the Owner Trustee nor the Indenture Trustee shall be affected by any notice to the contrary, unless and until such change is reflected in the Register. So long as any signatory to the Refunding 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 III thereto and otherwise in the manner provided in or pursuant to the Refunding Agreement unless it shall have specified some other account or manner of payment by notice to the Indenture Trustee consistent with this Section 2.04. (b) The Indenture Trustee, as agent for the Owner Trustee, shall exclude and withhold at the appropriate rate from each payment of Principal Amount of, interest on, Make-Whole Amount, if any, and other amounts due hereunder or under each Equipment Note (and such exclusion and withholding shall constitute payment in respect of such Equipment Note) any and all United States withholding taxes applicable thereto as required by law. The 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 such withholding shall constitute payment in respect of such Equipment Note) and timely pay the same to the appropriate authority in the name of and on behalf of the Note Holders, that it will file any necessary United States withholding tax returns or statements when due, and that as promptly as possible after the payment thereof it will deliver to each Note Holder (with a copy to the Owner Trustee and the Lessee) appropriate receipts showing the payment thereof, together with such additional documentary evidence as any such Note Holder, the Owner Participant and the Owner Trustee 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 and currently effective U.S. Internal Revenue Service Form 1001 or W-8 (or such successor form or forms as may be required by the United States Treasury Department) during the calendar year in which the payment hereunder or under the Equipment Note(s) held by such Holder is made (but prior to the making of such payment) or in either of the two preceding calendar years, and has not notified the Indenture Trustee of the withdrawal or inaccuracy of Trust Indenture 38 - 33 - such form prior to the date of such payment (and the Indenture Trustee has no reason to know 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 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 (and such withholding shall constitute payment in respect of such Equipment Note). If a Note Holder (x) which is a Non-U.S. Person has furnished to the Indenture Trustee a properly completed and currently effective U.S. Internal Revenue Service Form 4224 in duplicate (or such successor certificate, form or forms as may be required by the United States Treasury Department as necessary in order to avoid withholding of United States federal income tax), during the calendar year in which the payment is made (but prior to the making of such payment) or in either of the two 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 know 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 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 the Code or the regulations thereunder or the administrative interpretation thereof are at any time after the date hereof amended to require such withholding of United States federal income taxes from payments under the Equipment Notes held by such 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 such withholding shall constitute payment in respect of such Equipment Notes) 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 applicable law. None of the Owner Trustee, the Owner Participant or the Lessee shall have any liability for the failure of the Indenture Trustee to withhold taxes in the manner provided for herein or for any false, inaccurate or untrue evidence provided by a Holder hereunder. SECTION 2.05. Application of Payments. In the case of each Equipment Note, each payment of Principal Amount, Make-Whole Trust Indenture 39 - 34 - Amount, if any, and interest or other amounts due thereon shall be applied: First: to the payment of accrued interest on such Equipment Note (as well as any interest on any overdue Principal Amount, any overdue Make-Whole Amount, if any, and, to the extent permitted by law, any overdue interest and any other overdue amounts thereunder) to the date of such payment; Second: to the payment of the Principal Amount of such Equipment Note (or a portion thereof) then due thereunder; Third: to the payment of Make-Whole Amount, if any, and any other amount due hereunder or under such Equipment Note; and Fourth: the balance, if any, remaining thereafter, to the payment of the Principal Amount of such Equipment Note remaining unpaid (provided that such Equipment Note shall not be subject to redemption except as provided in Sections 2.10 and 2.11 hereof). The amounts paid pursuant to clause "Fourth" above shall be applied to the installments of Principal Amount of such Equipment Note in the inverse order of their normal maturity. SECTION 2.06. Termination of Interest in Trust Indenture Estate. A Note Holder shall not, as such, have any further interest in, or other right with respect to, the Trust Indenture Estate when the Principal 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 payable to such Note Holder hereunder and under the Lease and the Refunding Agreement by the Lessee, the Owner Participant and the Owner Trustee (collectively, the "Secured Obligations") shall have been paid in full. SECTION 2.07. Registration, Transfer and Exchange of Equipment Notes. The Indenture Trustee shall keep a register (the "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 Register shall be kept at the Corporate Trust Office of the Indenture Trustee. The Indenture Trustee is hereby appointed "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 Trust Indenture 40 - 35 - from the registered Holder thereof for the issuance of a new Equipment Note, specifying, in the case of a surrender for transfer, the name and address of the new Holder or Holders. Upon surrender for registration of transfer of any Equipment Note, the Owner Trustee shall execute, and the 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 unpaid portion of the Principal 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 unpaid portion of the Principal 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 Trustee 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 2.07 or under Section 2.08 hereof or otherwise under this Indenture) shall be the valid obligations of the Owner Trustee evidencing the same respective obligations, and entitled to the same security and benefits under this Indenture, as the Equipment Notes surrendered upon such registration of transfer or exchange. Every Equipment Note presented or surrendered for registration of transfer or exchange 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 Principal 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 Principal Amount marked on such new Equipment Note, as provided above, shall be deemed to have been made thereon. Neither the Indenture Trustee nor the Owner Trustee shall be required to exchange any surrendered Equipment Notes as provided above during the ten-day period preceding the Payment Date. The Indenture Trustee will promptly notify the Owner Trustee, the Owner Participant and Lessee of each registration of a transfer of an Equipment Note. Any such transferee of an Equipment Note, by its acceptance of an Equipment Note, agrees to the provisions of the Refunding Agreement applicable to Note Holders, and shall be deemed to have represented and warranted to the parties to the Refunding Trust Indenture 41 - 36 - Agreement as to the matters represented and warranted by the Subordination Agent in its capacity as the initial Holder of the Equipment Notes. Subject to compliance by the Note Holder and its transferee (if any) of the requirements set forth in this Section 2.07, the Indenture Trustee and the Owner Trustee shall use all reasonable efforts to issue new Equipment Notes upon transfer or exchange within 10 Business Days of the date an Equipment Note is surrendered for transfer or exchange. SECTION 2.08. Mutilated, Destroyed, Lost or Stolen Equipment Notes. If any Equipment Note shall become mutilated, destroyed, lost or stolen, the Owner Trustee shall, upon the written request of the Holder of such Equipment Note, execute and the Indenture Trustee shall authenticate and deliver in replacement thereof a new Equipment Note, payable in the same Principal Amount dated the same date and captioned as originally issued. If the Equipment Note being replaced has become mutilated, such Equipment Note shall be surrendered to the Indenture Trustee and a copy thereof shall be furnished to the Owner Trustee. If the Equipment Note being replaced has been destroyed, lost or stolen, the Holder of such Equipment Note shall furnish to the Lessee, the Owner Trustee, the Owner Participant and the Indenture Trustee such security or indemnity as may be reasonably required by them to save the Lessee, the Owner Trustee, the Owner Participant and the Indenture Trustee harmless and evidence satisfactory to the Lessee, the Owner Trustee, the Owner Participant and the Indenture Trustee of the destruction, loss or theft of such Equipment Note and of the ownership thereof. If a bank or trust company with a net worth of $200,000,000 or more is the Holder of any such destroyed, lost or stolen Equipment Note, then the written indemnity of such Person, signed by an authorized officer thereof, in favor of, delivered to and in form reasonably satisfactory to the Lessee, the Owner Participant, the Owner Trustee and the Indenture Trustee shall be accepted as satisfactory indemnity and security and no further indemnity or security shall be required as a condition to the execution and delivery of such new Equipment Note. Subject to compliance by the Note Holder of the requirements set forth in this Section 2.08, the Indenture Trustee and the Owner Trustee shall use all reasonable efforts to issue new Equipment Notes within 10 Business Days of the date of the written request therefor from the Note Holder. SECTION 2.09. Payment of Expenses on Transfer; Cancellation. (a) No service charge shall be made to a Note Holder for any registration of transfer or exchange of Equipment Notes, but the Indenture Trustee, as 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; provided, however, that none of the Lessee, the Owner Trustee, Trust Indenture 42 - 37 - the Indenture Trustee or the Owner Participant shall bear costs of registration, transfer or exchange in connection with the consummation of the Refinancing Transaction. (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 2.10. Mandatory Redemptions of Equipment Notes. The Equipment Notes are subject to redemption as provided in this Section 2.10 and Section 2.11 and purchase as provided in Section 2.12. On the date on which Lessee is required pursuant to Section 11(a) of the Lease to make payment for an Event of Loss with respect to the Engine, all of the Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of the unpaid Principal Amount thereof, together with all accrued interest thereon to, but not including, the date of redemption and all other amounts payable hereunder or under the Refunding Agreement to the Note Holders but without Make-Whole Amount, all in the order of priority specified in Section 3.02 hereof. SECTION 2.11. Redemptions; Notice of Redemption. (a) Neither any redemption of any Equipment Note nor any purchase by the Owner Trustee of any Equipment Note may be made except to the extent and in the manner expressly permitted by this Indenture. No purchase of any Equipment Note may be made by the Indenture Trustee. (b) Notice of redemption or purchase with respect to the Equipment Notes shall be given by the Indenture Trustee by first-class mail, postage prepaid, mailed not less than 15 nor more than 60 days prior to the applicable redemption date, to each Note Holder of such Equipment Notes to be redeemed or purchased, at such Note Holder's address appearing in the Register. All notices of redemption or purchase 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 interest on such Equipment Notes shall cease to accrue on and after such redemption date, and (4) the place or places where such Equipment Notes are to be surrendered for payment of the redemption price. (c) On or before the redemption date, the Owner Trustee (or any Person on behalf of the Owner Trustee) shall, to the extent an amount equal to the redemption price for the Equipment Notes to be redeemed or purchased on the redemption date shall not then be held in the Trust Indenture Estate, deposit or cause to be deposited with the Indenture Trustee by 12:00 noon, New York City time, on the redemption date in Trust Indenture 43 - 38 - immediately available funds the redemption price of the Equipment Notes to be redeemed or purchased. (d) Notice of redemption or purchase having been given as aforesaid, the Equipment Notes to be redeemed or purchased shall, on the redemption date, become due and payable at the Corporate Trust Office of the Indenture Trustee, and from and after such redemption date (unless there shall be a default in the payment of the redemption price) any such Equipment Notes then outstanding shall cease to bear interest. Upon surrender of any such Equipment Note for redemption or purchase in accordance with said notice, such Equipment Note shall be redeemed at the redemption price. If any Equipment Note called for redemption or purchase shall not be so paid upon surrender thereof for redemption, the principal amount thereof shall, until paid, continue to bear interest from the applicable redemption date at the interest rate in effect for such Equipment Note as of such redemption date. SECTION 2.12. Option to Purchase Equipment Notes. Either the Owner Trustee or the Owner Participant may, upon the events and subject to the terms and conditions and for the price set forth in this Section 2.12, purchase all but not less than all of the Equipment Notes outstanding hereunder, and each Note Holder agrees that it will, upon such events and subject to such terms and conditions and upon receipt of such price, sell, assign, transfer and convey to such purchaser or its nominee (without recourse or warranty of any kind except as to its title to the Equipment Notes and except against Liens on such Equipment Notes arising by, through or under such Holder), all of the right, title and interest of such Note Holder in and to the Trust Indenture Estate, this Indenture and the Equipment Notes held by it, and such purchaser or its nominee shall assume all of such Holder's obligations under the Refunding Agreement and hereunder. Such option to purchase the Equipment Notes may be exercised by the Owner Trustee or the Owner Participant upon any of the following events, and, in any such event, the purchase price thereof shall equal for each Equipment Note the aggregate unpaid Principal Amount thereof, plus accrued and unpaid interest thereon to, but not including, the date of purchase and all other amounts (other than the Make-Whole Amount, except as provided in the next sentence) then payable hereunder or under the Refunding Agreement to the Holder thereof. Such option to purchase the Equipment Notes may be exercised: (i) upon an Indenture Trustee Event or (ii) in the event there shall have occurred and be continuing a Lease Event of Default, provided that if such option is exercised pursuant to this clause (ii) at a time when there shall have occurred and be continuing for less than 120 days a Lease Event of Default (and there is no Indenture Trustee Event), the purchase price thereof shall equal the price provided in the Trust Indenture 44 - 39 - preceding sentence plus the Make-Whole Amount, if any; provided further, that under no circumstances shall the Make-Whole Amount be payable by the Lessee. Such option to purchase the Equipment Notes may be exercised by the Owner Trustee or the Owner Participant giving written notice of its election of such option to the Indenture Trustee, which notice shall specify a date for such purchase not more than 30 days or less than 15 days after the date of such notice. The Indenture Trustee shall not exercise any of the remedies hereunder or, without the consent of the Owner Trustee or the Owner Participant, under the Lease, during the period from the time that a notice of exercise by the Owner Participant of such option to purchase becomes irrevocable until the date on which such purchase is required to occur pursuant to the terms of the preceding sentence. Such election to purchase the Equipment Notes shall become irrevocable upon the fifteenth day preceding the date specified in the written notice described in the first sentence of this paragraph. If the Owner Trustee or the Owner Participant on or before the date of such purchase shall so request, the Note Holders will comply with all the provisions of Section 2.07 to enable new Equipment Notes to be issued to the Owner Trustee or the Owner Participant or its nominee in such denominations as the Owner Trustee or the Owner Participant shall request. All taxes and charges required pursuant to Section 2.09 in connection with the issuance of such new Equipment Note shall be borne by the Owner Participant. SECTION 2.13. Subordination. (a) The Owner Trustee and, by acceptance of its Equipment Notes of any Series, each Note Holder of such Series, hereby agree that no payment or distribution shall be made on or in respect of the Secured Obligations owed to such Note Holder of such Series, including any payment or distribution of cash, property or securities after the commencement of a proceeding of the type referred to in Section 4.02(g), (h) or (i) hereof, except as expressly provided in Articles II and III hereof. (b) By the acceptance of its Equipment Notes of any Series (other than Series A), each Note Holder of such Series agrees that in the event that such Note Holder, in its capacity as a Note Holder, shall receive any payment or distribution on any Secured Obligations in respect of such Series which it is not entitled to receive under this Section 2.13 or Article III hereof, it will hold any amount so received in trust for the Senior Holder or Senior Holders (as defined in Section 2.13(c) hereof) and will forthwith turn over such payment to the Indenture Trustee in the form received to be applied as provided in Articles II and III hereof.

In the event of any default by the Lessee in any obligation under the Lease other than the payment of Basic Rent, if such default can be remedied by the payment of money and the Owner Trustee shall have been furnished by the Owner Participant with all funds necessary for remedying such default, the Owner Participant may, within fifteen calendar days (or such longer period ending on the second day after the expiry of any applicable grace period specified in the Lease with respect to such default) after notice from the Indenture Trustee or the Lessee of such default, without the consent or concurrence of any Note Holder, instruct the Owner Trustee to exercise the Owner Trustee's rights under Section 21(d) of the Lease to perform such obligation on behalf of the Lessee. Solely for the purpose of determining whether there exists an Indenture Event of Default, (a) any timely payment by the Owner Participant pursuant to, and in compliance with, the first sentence of this Section 4.03 shall be deemed to remedy (but solely for purposes of this Indenture) any default by the Lessee in the payment of Basic Rent theretofore due and payable and to remedy (but solely for purposes of this Indenture) any default by the Owner Trustee in the payment of any amount due and payable under the Equipment Notes or hereunder, and (b) any timely performance by the Owner Trustee of any obligation of the Lessee under the Lease pursuant to, and in compliance with, the second sentence of this Section 4.03 shall be deemed to remedy (but solely for purposes of this Indenture) any default by the Trust Indenture 59 - 54 - Lessee under the Lease to the same extent that like performance by the Lessee itself would have remedied such default (but any such payment or performance shall not relieve the Lessee of its duty to pay all Rent and perform all of its obligations pursuant to the Lease). If, on the basis specified in the preceding sentence, such Lease Event of Default shall have been remedied, then any declaration pursuant to the Lease that the Lease is in default, and any declaration pursuant to this Indenture that the Equipment Notes are due and payable or that an Indenture Event of Default exists hereunder, based upon such Lease Event of Default, shall be deemed to be rescinded, and the Owner Participant or the Owner Trustee, as the case may be, shall (to the extent of any such payments made by it) be subrogated to the rights of the Note Holders hereunder to receive such payment of Rent from the Indenture Trustee (and the payment of interest on account of such Rent being overdue), and shall be entitled, so long as no other Indenture Default or Indenture Event of Default shall have occurred and be continuing, to receive, subject to the terms of this Indenture, such payment upon receipt thereof by the Indenture Trustee; provided that the Owner Participant shall not otherwise attempt to recover any such amount paid by it on behalf of the Lessee pursuant to this Section 4.03 except by demanding of the Lessee payment of such amount, or by commencing an action at law against the Lessee and obtaining and enforcing a judgment against the Lessee for the payment of such amount or taking appropriate action in a pending action at law against the Lessee or by demanding Excepted Payments or Excepted Rights; provided, however, that at no time while an Indenture Event of Default shall have occurred and be continuing shall any such demand be made or shall any such action be commenced (or continued) and any amounts nevertheless received by the Owner Participant in respect thereof shall be held in trust for the benefit of, and promptly paid to, the Indenture Trustee for distribution as provided in Section 3.03 hereof; and provided, further, that (x) this Section 4.03 shall not apply with respect to any default in the payment of Basic Rent due under the Lease, if the Lessee itself shall have theretofore failed to pay Basic Rent in the manner required under the Lease (after giving effect to any applicable grace period) as to (i) each of the three Basic Rent Payment Dates immediately preceding the date of such default or (ii) in the aggregate more than six Basic Rent Payment Dates, (y) the second sentence of this Section 4.03 shall cease to apply, and no payment by the Owner Participant in respect of Supplemental Rent or performance of any obligation of the Lessee under the Lease by the Owner Trustee shall be deemed to remedy or to have remedied any Lease Event of Default for the purposes of this Indenture, if during the 12-month period immediately preceding the Trust Indenture 60 - 55 - relevant default by the Lessee there shall have been expended by the Owner Participant pursuant to the second sentence of this Section 4.03 (and shall have not been reimbursed by the Lessee or any Permitted Sublessee themselves to the Owner Trustee for distribution to the Owner Participant) an amount in excess of $3,500,000, and (z) neither the Owner Trustee nor the Owner Participant shall (without the prior written consent of a Majority in Interest of Note Holders) have the right to cure any Lease Default or Lease Event of Default except as specified in this Section 4.03. SECTION 4.04. Remedies. (a) If an Indenture Event of Default shall have occurred and be continuing and so long as the same shall be continuing unremedied, and if the Equipment Notes shall have been accelerated pursuant to Section 4.04(b) or 4.04(c) hereof, then and in every such case the Indenture Trustee may (subject to the rights of the Owner Participant or the Owner Trustee to cure any such Indenture Event of Default set forth in Section 4.03 hereof and the obligations of the Indenture Trustee set forth in this Section 4.04(a) and subject to Section 10.05 hereof) exercise any or all of the rights and powers and pursue any and all of the remedies pursuant to this Article IV and shall have and may exercise all of the rights and remedies of a secured party under the Uniform Commercial Code and, in the event such Indenture Event of Default is an Indenture Event of Default referred to in paragraph (a) of Section 4.02 hereof, the Indenture Trustee may (subject as aforesaid), at the direction of a Majority in Interest of Note Holders, exercise any and all of the remedies pursuant to Section 18 of the Lease and pursuant to any Sublease Assignment and may take possession of all or any part of the properties covered or intended to be covered by the Lien and security interest created hereby or pursuant hereto but, in the case of the Engine, only as permitted by Section 18 of the Lease, and may exclude the Owner Participant, the Owner Trustee and the Lessee and all Persons claiming under any of them or wholly or partly therefrom; provided, however, that the Indenture Trustee shall give the Owner Trustee and the Owner Participant ten days' prior written notice of the initial exercise of such remedies by the Indenture Trustee under the Lease (if not stayed or otherwise precluded by applicable law from giving such notice); provided, further, that the Indenture Trustee shall give the Owner Trustee and the Owner Participant twenty days' prior written notice of its intention to sell the Engine. Without limiting any of the foregoing, it is understood and agreed that the Indenture Trustee may exercise any right of sale of the Engine available to it, even though it shall not have taken possession of the Engine and shall not have possession thereof at the time of such sale. Trust Indenture 61 - 56 - Anything in this Indenture to the contrary notwithstanding, the Indenture Trustee shall not be entitled to exercise any remedy hereunder if there shall have occurred or be continuing a Lease Event of Default unless the Indenture Trustee shall have exercised or concurrently be exercising one or more of the remedies provided for in Section 18 of the Lease to terminate the Lease or take possession and/or sell the Engine; provided, however, that such requirement to exercise one or more of such remedies under the Lease shall not apply in circumstances where the Indenture Trustee is, and has been, for a continuous period in excess of 60 days or such other period as may be specified in Section 1110(a)(1)(A) of the Bankruptcy Code (such 60-day or other period being the "Section 1110 Period"), stayed or prohibited by applicable law or court order from exercising such remedies under the Lease (a "Continuous Stay Period"); provided further, however, that the requirement to exercise one or more of such remedies under the Lease shall nonetheless be applicable during a Continuous Stay Period subsequent to the expiration of the Section 1110 Period to the extent that the continuation of such Continuous Stay Period subsequent to the expiration of the Section 1110 Period (A) results from an agreement by the trustee or the debtor-in-possession in such proceeding during the Section 1110 Period with the approval of the relevant court to perform the Lease in accordance with Section 1110(a)(1)(A) of the Bankruptcy Code and continues to perform as required by Section 1110(a)(1) of the Bankruptcy Code or (B) is an extension of the Section 1110 Period with the consent of the Indenture Trustee pursuant to Section 1110(b) of the Bankruptcy Code or (C) results from the Lessee's assumption during the Section 1110 Period with the approval of the relevant court of the Lease pursuant to Section 365 of the Bankruptcy Code or (D) is the consequence of the Indenture Trustee's own failure to give any requisite notice to any Person (unless the Indenture Trustee is stayed or otherwise precluded by applicable law from giving such notice). In the event that the applicability of Section 1110 of the Bankruptcy Code to the Engine is being contested by the Lessee in judicial proceedings, so long as the Indenture Trustee fails to participate in such proceedings, the Owner Trustee shall have the right (without affecting in any way any right or remedy of the Indenture Trustee hereunder) to participate in such proceedings. The foregoing shall not preclude the Indenture Trustee from notifying any Permitted Sublessee that payments under any Assigned Sublease are to be made directly to it pursuant to the terms of the relevant Sublease Assignment, or, except as expressly provided above, from exercising its rights or remedies hereunder and under the other Operative Documents. For the avoidance of doubt, it is expressly understood and agreed, subject only to the immediately preceding paragraph, that the above-described inability of the Indenture Trustee to exercise any right or remedy under the Lease shall in no event and under Trust Indenture 62 - 57 - no circumstance prevent the Indenture Trustee from otherwise exercising all of its rights, powers and remedies under this Indenture, including without limitation this Article IV. (b) If an Indenture Event of Default referred to in clause (g), (h) or (i) of Section 4.02 hereof shall have occurred, or a Lease Event of Default under clause (e), (f) or (g) of Section 17 of the Lease shall have occurred, then and in every such case the unpaid Principal Amount of all Equipment Notes then outstanding, together with accrued but unpaid interest and all other amounts due thereunder and hereunder, shall immediately and without further act become due and payable without presentment, demand, protest or notice, all of which are hereby waived. (c) If any Indenture Event of Default not specified in Section 4.04(b) hereof 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), subject to Section 4.03 hereof, at any time, by written notice or notices to the Owner Trustee, declare the unpaid Principal Amount of all Equipment Notes to be due and payable, whereupon the unpaid Principal Amount of all Equipment Notes then outstanding, together with accrued but unpaid interest thereon and all other amounts due thereunder and hereunder, shall immediately become due and payable without presentment, demand, protest or further notice, all of which are hereby waived. (d) Sections 4.04(b) and (c), however, are subject to the condition that, if at any time after the Principal Amount of the Equipment Notes shall have become so due and payable, and before any judgment or decree for the payment of the money so due, or any thereof, shall be entered, all overdue payments of interest upon the Equipment Notes and all other amounts payable under the Equipment Notes (except the Principal Amount of the Equipment Notes which by such declaration shall have become payable) shall have been duly paid and every other Indenture Default and Indenture Event of Default with respect to any covenant or provision of this 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 and its consequences; but no such rescission or annulment shall extend to or affect any subsequent Indenture Default or Indenture Event of Default or impair any right consequent thereon. Any acceleration pursuant to Sections 4.04(b) and (c) shall be automatically rescinded and any related declaration of an Indenture Event of Default annulled in the event that the Owner Trustee or the Owner Participant, as the case may be, shall Trust Indenture 63 - 58 - have cured, in accordance with Section 4.03, the Indenture Event of Default that resulted in such acceleration. No Make-Whole Amount shall become payable on the Equipment Notes as a result of any acceleration under Section 4.04(b) or 4.04(c). (e) Each Note Holder shall be entitled, at any sale pursuant to Section 18 of the Lease, to credit against any purchase price bid at such sale by such Note Holder all or any part of the unpaid obligations owing to such Note Holder and secured by the Lien of this Indenture. The Owner Trustee or Owner Participant may be a cash purchaser at any such sale. (f) Notwithstanding anything contained herein, so long as the Pass Through Trustee under any Pass Through Trust Agreement or the Subordination Agent on its behalf is a Note Holder, the Indenture Trustee will not be authorized or empowered to acquire title to any property in the Trust Indenture Estate or take any action with respect to any property in the Trust Indenture Estate so acquired by it if such acquisition or action would cause any trust created pursuant to the Trust Agreement to fail to qualify as a "grantor trust" for federal income tax purposes. SECTION 4.05. Return of the Engine, etc. (a) Subject to the rights of the Owner Trustee and the Owner Participant under Section 4.03 hereof and unless the Owner Participant shall have theretofore purchased the Equipment Notes pursuant to Section 2.12 hereof, if an Indenture Event of Default shall have occurred and be continuing and the Equipment Notes shall have been accelerated pursuant to Section 4.04(b) or 4.04(c) hereof, at the request of the Indenture Trustee the Owner Trustee 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 Trust Indenture Estate; provided that the Indenture Trustee shall at the time be entitled to obtain such possession under Section 4.04(a) and the other applicable provisions of this Indenture. If the Owner Trustee 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 Trustee to execute and deliver such instruments and documents to the Indenture Trustee, to the entry of which judgment the Owner Trustee hereby specifically consents to the fullest extent it may lawfully do so, and (ii) to the extent permitted by law, pursue Trust Indenture 64 - 59 - all or part of the Trust Indenture Estate wherever it may be found (but not in violation of Section 10.05 hereof or of the Lease) and may enter any of the premises of the Lessee wherever such Trust Indenture Estate may be or be supposed to be and search for and take possession of and remove the same (but not in violation of Section 10.05 hereof or of the Lease). 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 Indenture. (b) Upon a Lease Event of Default which is continuing, the Indenture Trustee may, from time to time, at the expense of the Trust Indenture Estate, make all such expenditures for maintenance, insurance, repairs, replacements, alterations, additions and improvements to and of the Trust Indenture Estate, as it may deem proper (it being understood and agreed that the provisions hereof shall not be construed so as to expand the obligations of the Lessee under the Lease, including Section 16 thereof). In each such case, the Indenture Trustee shall have the right to maintain, use, operate, store, lease, control or manage the Trust Indenture Estate and to carry on the business (without limiting the express provisions of Section 5.10 hereof) and to exercise all rights and powers of the Owner Participant and the Owner Trustee relating to the Trust Indenture Estate, as the Indenture Trustee shall deem best, including the right to enter into any and all such agreements with respect to the maintenance, insurance, use, operation, storage, leasing, control, management or disposition of the Trust Indenture Estate or any part thereof as the Indenture Trustee may determine; and the Indenture Trustee shall be entitled to collect and receive directly all tolls, rents (including Rent), revenues, issues, income, products and profits of the Trust Indenture Estate and every part thereof, except Excepted Payments, without prejudice, however, to the right of the Indenture Trustee under any provision of this Indenture to collect and receive all cash held by, or required to be deposited with, the Indenture Trustee hereunder, except Excepted Payments. The Indenture Trustee shall, pursuant to the exercise of its remedies under this Article IV, to the extent permitted by applicable law, be entitled to the appointment of a receiver for all or any part of the Trust Indenture Estate, whether such receivership be incidental to a proposed sale of the Trust Indenture Estate or otherwise, and the Owner Trustee hereby consents to the appointment of such receiver and will not oppose any such appointment. Such tolls, rents (including Rent), revenues, issues, income, products and profits shall be applied to pay the expenses of the use, operation, storage, leasing, control, management or disposition of the Trust Indenture Estate and of conducting the business thereof, and of all maintenance, repairs, replacements, alterations, additions and improvements, and to make all payments which the Indenture Trustee may be required or Trust Indenture 65 - 60 - may elect to make, if any, for taxes, assessments, insurance or other proper charges upon the Trust Indenture Estate or any part thereof (including the employment of engineers and accountants to examine, inspect and make reports upon the properties and books and records of the Owner Trustee), and all other payments that the Indenture Trustee may be required or authorized to make under any provision of this 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. SECTION 4.06. Remedies Cumulative. Each and every right, power and remedy given to the Indenture Trustee specifically or otherwise in this 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 Trustee or the Lessee or to be an acquiescence therein. SECTION 4.07. Discontinuance of Proceedings. In case the Indenture Trustee or any Note Holder shall have instituted any proceeding to enforce any right, power or remedy under this 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 or such Note Holder, then and in every such case the Owner Trustee, the Indenture Trustee, the Note Holders and the Lessee shall, subject to any determination in such proceedings, be restored to their former positions and rights hereunder with respect to the Trust Indenture Estate, and all rights, remedies and powers of the Indenture Trustee and the Note Holders shall continue as if no such proceedings had been instituted. SECTION 4.08. Waiver of Past Indenture Defaults. Upon written instructions from a Majority in Interest of Note Holders, the Indenture Trustee shall waive any past Indenture Default hereunder and its consequences and upon any such waiver such Indenture Default shall cease to exist and any Indenture Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Indenture Default or impair any right Trust Indenture 66 - 61 - consequent thereon; provided, however, that in the absence of written instructions from the Holders of all Equipment Notes then outstanding, the Indenture Trustee shall not waive any Indenture Default (i) in the payment of the Principal Amount of or interest on any Equipment Note then outstanding, or (ii) in respect of a covenant or provision hereof which, under Article IX hereof, cannot be modified or amended without the consent of each Note Holder. ARTICLE V DUTIES OF THE INDENTURE TRUSTEE SECTION 5.01. Notice of Indenture Event of Default. In the event the Indenture Trustee shall have knowledge of an Indenture Event of Default, or shall have knowledge of an Indenture Default arising either from a failure to pay Rent or a Lease Default of the type referred to in the second sentence of Section 4.03, the Indenture Trustee shall give prompt notice thereof to the Owner Trustee, the Owner Participant and the Lessee by facsimile, telex, telegraph or telephone (confirmed by written notice in the manner provided by Section 10.06 hereof), and to each Note Holder by first-class mail. Subject to the terms of Sections 2.12, 4.03, 4.04, 4.08, 4.09, 5.03, 5.10 and 10.05 hereof and of this Section 5.01, the Indenture Trustee shall take such action, or refrain from taking such action, with respect to any Indenture Event of Default or Indenture 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 5.03 hereof, if the Indenture Trustee shall not have received instructions as above provided within 20 calendar days after mailing notice of such Indenture Default or Indenture Event of Default to the Note Holders, the Indenture Trustee may, subject to instructions thereafter received pursuant to the preceding provisions of this Section 5.01, take such action, or refrain from taking such action, but shall be under no duty to take or refrain from taking any action, with respect to such Indenture Default or Indenture Event of Default as it shall determine to be advisable and in the best interests of the Note Holders and shall use the same degree of care and skill in connection therewith as a prudent person would use under the circumstances in the conduct of its own affairs; provided that the Indenture Trustee may not sell the Engine or any part thereof without the consent of a Majority in Interest of Note Holders. In the event the Indenture Trustee shall at any time elect to foreclose or otherwise enforce this Indenture, the Indenture Trustee shall forthwith notify, to the extent (in the case of any such party) not stayed or otherwise prohibited by applicable law, the Owner Participant, the Note Holders, the Owner Trustee and Trust Indenture 67 - 62 - the Lessee. For all purposes of this Indenture, in the absence of actual knowledge on the part of an officer in the Corporate Trust Office, in the case of the Indenture Trustee, or its Corporate Trust Administration Department, in the case of the Owner Trustee, the Indenture Trustee or the Owner Trustee, as the case may be, shall not be deemed to have knowledge of an Indenture Event of Default (except, in the case of the Indenture Trustee, the failure of the Lessee to pay any installment of Rent when due, if any portion of such installment was then required to be paid to the Indenture Trustee, which failure shall constitute knowledge of an Indenture Default for purposes of the first sentence of this Section 5.01) unless notified in writing by the Lessee, the Owner Trustee or one or more Note Holders or, in the case of the Owner Trustee, by the Indenture Trustee. SECTION 5.02. Action Upon Instructions. Subject to the terms of Sections 2.12, 4.03, 4.04, 4.08, 4.09, 5.01, 5.03, 5.10, 9.01 and 10.05 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 take such of the following actions as may be specified in such instructions: (i) exercise such election or option, or make such decision or determination, or give such notice, consent, waiver or approval or exercise such right, remedy or power to take such other action hereunder or under any other Indenture Document or in respect of any part or all of the Trust Indenture Estate as shall be specified in such instructions; (ii) take such action with respect to, or to preserve or protect, the Trust Indenture Estate (including the discharge of Liens) as shall be specified in such instructions and as are consistent with this Indenture; and (iii) take such other action in respect of the subject matter of this Indenture as is consistent with the terms hereof and of the other Indenture Documents. The Indenture Trustee will execute and the Owner Trustee will file or cause to be filed such continuation statements with respect to financing statements relating to the security interest created hereunder in the Trust Indenture Estate as may be specified from time to time in written instructions of a Majority in Interest of Note Holders (which instructions may, by their terms, be operative only at a future date and which shall be accompanied by the execution form of such continuation statement so to be filed); provided that, notwithstanding the foregoing, the Indenture Trustee may, but shall not be obligated to, execute and file or cause to be filed any financing statement which it from time to time deems appropriate or any continuation statement that the Lessee, in discharge of its obligations under Section 3(v) of the Refunding Agreement or any other Operative Document, may so request. Notwithstanding the foregoing or anything in this Indenture to the contrary, the Indenture Trustee may, on the advice of its counsel and without the consent or approval of any Note Holder, approve any counsel asked to opine on any matters under Section 11(b)(ii) of the Refunding Trust Indenture 68 - 63 - Agreement, Section 6(a)(iii) of the Lease or under this Indenture and approve any opinion issued by such counsel. None of the Owner Participant, the Owner Trustee or the Lessee have any liability for the failure of the Indenture Trustee to discharge its obligations hereunder. SECTION 5.03. Indemnification. The Indenture Trustee shall not be required to take any action or refrain from taking any action under Section 5.01 (other than the first sentence thereof) or 5.02 or Article IV hereof unless the Indenture Trustee shall have been indemnified against any liability, cost or expense (including counsel fees) that may be incurred in connection therewith. The Indenture Trustee shall not be under any obligation to take any action under this Indenture and nothing in this Indenture contained shall require the Indenture Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. The Indenture Trustee shall not be required to take any action under Section 5.01 (other than the first sentence thereof) or 5.02 or Article IV hereof, nor shall any other provision of this Indenture 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 of the other Indenture Documents or is otherwise contrary to law. SECTION 5.04. No Duties Except as Specified in Indenture or Instructions. The Indenture Trustee shall not have any duty or obligation to maintain, use, operate, store, lease, control, manage, sell, dispose of, insure or otherwise deal with the Engine or any other part of the Trust Indenture Estate, or to otherwise take or refrain from taking any action under, or in connection with, this Indenture or any Indenture Document or any part of the Trust Indenture Estate, except as expressly provided by the terms of this Indenture or as expressly provided in written instructions from Note Holders as provided in this Indenture and no implied duties or obligations shall be read into this Indenture against the Indenture Trustee. It is understood that, as between the Indenture Trustee and the Note Holders, with respect to all matters left to the discretion of the Indenture Trustee hereunder, or under any Indenture Document, the Indenture Trustee shall have the right to request written instructions from the Note Holders and, pending receipt of such instructions from the Note Holders or the required percentage thereof as provided herein, the Indenture Trustee shall not be required to take any such discretionary action hereunder; provided, however, that if the Indenture Trustee shall request written instructions pursuant to this Section 5.04, it will use reasonable efforts to seek and Trust Indenture 69 - 64 - obtain such instructions promptly so as not unreasonably to delay the proposed action of Lessee in respect of which the instructions are sought. . 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 Article VII hereof or any other Operative Document) promptly take such action as may be necessary to duly discharge all Lenders' Liens on any part of the Trust Indenture Estate attributable to it in its individual capacity. SECTION 5.05. No Action Except Under Lease, Refunding Agreement, Indenture or Instructions. The Owner Trustee and the Indenture Trustee agree that they will not use, operate, store, lease, control, manage, sell, dispose of or otherwise deal with, or place Liens on, the Engine or any other part of the Trust Indenture Estate except (i) as required or permitted by the terms of the Lease or the Refunding Agreement, or (ii) in accordance with the powers granted to, or the authority conferred upon, the Owner Trustee and the Indenture Trustee pursuant to this Indenture and in accordance with the terms hereof. SECTION 5.06. Replacement Engine. (a) If at any time and from time to time, the Engine may, or may be required to, be replaced under Section 6(a) or 11(a) of the Lease by a Replacement Engine, as the case may be, in accordance with the provisions of this Section 5.06 and the provisions of said Sections of the Lease, the Owner Trustee shall, at such time or times, but subject to compliance with the conditions to such replacement set forth in the Lease, direct the Indenture Trustee to execute and deliver to or as directed in writing by the Owner Trustee an appropriate instrument releasing the Engine as appropriate from the Lien of this Indenture and the Indenture Trustee shall execute and deliver such instrument as aforesaid, but only upon receipt by or deposit with the Indenture Trustee of the following: (1) A written request from the Owner Trustee, requesting such release and specifically describing the Engine so to be released and the Replacement Engine. (2) A certificate signed by a duly authorized officer of the Lessee stating the following: A. [Intentionally reserved] B. With respect to the replacement of the Engine: (i) a description of the Engine which shall be identified by manufacturer's name and serial number; Trust Indenture 70 - 65 - (ii) a description of the Replacement Engine (including the manufacturer's name and serial number) to be received as consideration for the Engine; (iii) that on the date of the Indenture Supplement relating to the Replacement Engine the Owner Trustee will hold title to the Replacement Engine free and clear of all Liens except Permitted Liens, that such Replacement Engine will on such date be in good operating condition, and that the Replacement Engine is the same or an improved model as the Engine; (iv) the value, remaining useful life and utility of the Replacement Engine as of the date of such certificate (which value, remaining useful life and utility shall not be less than the then value, remaining useful life and utility of the Engine, assuming the Engine was in the condition and repair required to be maintained under the Lease (but without regard to hours and cycles until overhaul)); (v) that no Lease Event of Default has occurred and is continuing or would result from the making and granting of the request for release and the addition of the Replacement Engine; and (vi) that each of the conditions specified in Section 11(b) of the Lease with respect to the Replacement Engine have been satisfied.

The Indenture Trustee shall at any time and from time to time at the request of the Lessee execute an appropriate written instrument or instruments to confirm the release of any Part from the Lien of this Indenture as provided in this Section 5.06(b), but only upon receipt by the Indenture Trustee of an Officers' Certificate of Lessee confirming such release is authorized by the terms hereof. SECTION 5.07. Indenture Supplements for Replacements. In the event of the substitution of a Replacement Engine as contemplated by Section 11 of the Lease, the Owner Trustee and the Indenture Trustee agree for the benefit of the Note Holders and the Lessee, subject to fulfillment of the conditions precedent and compliance by the Lessee with its obligations set Trust Indenture 72 - 67 - forth in Section 11 of the Lease, to execute and deliver the appropriate instruments as contemplated by Section 5.06 hereof, and execute and deliver to the Lessee (or any relevant Permitted Sublessee) an appropriate instrument releasing the Engine being replaced from the Lien of this Indenture. SECTION 5.08. Effect of Replacement. In the event of the substitution of a Replacement Engine as contemplated by Section 11 of the Lease and Section 5.06 hereof, all provisions of this Indenture relating to the Engine being replaced shall be applicable to such Replacement Engine with the same force and effect as if such Replacement Engine was the same engine as the Engine being replaced. SECTION 5.09. Notices, etc. Where this Indenture expressly provides for notice to Note Holders, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Note Holder entitled thereto, at his last address as it appears in the Register. In any case where notice to Note Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Note Holder shall affect the sufficiency of such notice with respect to other Note Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Note Holders shall be filed with the Indenture Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. In case, by reason of the suspension of or irregularities in regular mail service, it shall be impracticable to mail notice to the Note Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving of such notice.

Trust Indenture 74 - 69 - (c) at all times whether or not an Indenture Event of Default has occurred and is continuing, the Owner Trustee and the Owner Participant shall have the right, together with the Indenture Trustee, (i) to receive from the Lessee or any Permitted Sublessee all notices, certificates, reports, filings, opinions of counsel and other documents and all information which any thereof is permitted or required to give or furnish to the Owner Trustee pursuant to any Operative Document (including pursuant to Section 10 of the Lease), (ii) to exercise inspection rights pursuant to Section 7 of the Lease, (iii) to retain all rights with respect to insurance maintained for its own account which Section 12 of the Lease specifically confers on the Owner Participant and (iv) to exercise, to the extent necessary to enable it to exercise its rights under Section 4.03 hereof, the rights of the Owner Trustee under Section 21(d) of the Lease and to give notices of default under Section 17 of the Lease;

Notwithstanding the foregoing provisions of this Section 5.10, but subject always to Section 10.05 hereof and to the rights of the Owner Participant under Sections 2.12 and 4.03 hereof, the Indenture Trustee shall at all times have the right, to the exclusion of the Owner Trustee and the Owner Participant, to (A) demand, collect, sue for or otherwise receive and enforce the payment of all Rent due and payable under the Lease (other than any thereof constituting an Excepted Payment or Excepted Right), (B) declare the Lease to be in default under Section 18 thereof and (C) subject only to the provisions of Sections 4.03 and 4.04(a) hereof, exercise the remedies set forth in such Section 18 (other than in connection with Excepted Payments) and in Article IV hereof. Trust Indenture 75 - 70 - SECTION 5.11. Evidence of Action Taken by Note Holder. Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Note Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Note Holders in person or by agent duly appointed in writing, and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Indenture Trustee and, if expressly required herein, to the Owner Trustee.

Except as aforesaid any such action taken by the Note Holder shall be conclusive and binding upon such Note Holder and upon all future Note Holders and owners of such Equipment Note and of any Equipment Notes issued in exchange or substitution therefor, irrespective of whether or not any notation in regard thereto is made upon any such Equipment Note. Any action taken by the Note Holders of the percentage in aggregate Principal Amount of the Equipment Notes specified in this Indenture in connection with such action shall be conclusively binding upon the Owner Trustee, the Indenture Trustee and the Note Holders.

The Indenture Trustee shall assume, and shall be fully protected in assuming, that the Owner Trustee is authorized by the Trust Agreement to enter into this Indenture and to take all action to be taken by it pursuant to the provisions hereof, and shall not inquire into the authorization of the Owner Trustee with respect thereto. In the administration of the trusts hereunder, the Owner Trustee and the Indenture Trustee each may execute any of the trusts or powers hereof and perform its powers and duties hereunder directly or (except in the case of the Indenture Trustee's obligations under the third sentence of Section 2.04(a)) through agents or attorneys and shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care hereunder.

SECTION 6.08. May Become Note Holder. Each of the institutions acting as Owner Trustee and Indenture Trustee hereunder may become a Note Holder and have all rights and benefits of a Note Holder to the same extent as if it were not the institution acting as Owner Trustee or Indenture Trustee, as the case may be.

ARTICLE VII INDEMNIFICATION OF INDENTURE TRUSTEE BY OWNER TRUSTEE SECTION 7.01. Scope of Indemnification. The Owner Trustee, not individually but solely in its capacity as owner trustee under the Trust Agreement, hereby agrees, whether or not any of the transactions contemplated hereby shall be consummated but except as otherwise provided in Section 2.03 hereof, to assume liability for, and does hereby indemnify, protect, save and keep harmless the Indenture Trustee, in its individual capacity and as Indenture Trustee, and its successors, permitted assigns, agents and servants solely from the Trust Estate, from and against any and all liabilities, obligations, losses, damages, penalties, taxes (excluding any taxes payable by the Indenture Trustee on or measured by any compensation received by the Indenture Trustee for its services under this Indenture), claims, actions, suits, and reasonable out-of-pocket costs, expenses or disbursements (including reasonable legal fees and expenses) of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Indenture Trustee (in its individual capacity and as trustee) from and after the Restatement Date (whether or not also agreed to be indemnified against by any other Person under any other document) in any way relating Trust Indenture 80 - 75 - to or arising out of this Indenture, the Trust Agreement, the Equipment Notes, the other Indenture Documents or the enforcement of any of the terms of any thereof, or in any way relating to or arising out of the manufacture, purchase, acceptance, nonacceptance, rejection, ownership, delivery, lease, sublease, possession, use, operation, condition, sale, return or other disposition of the Engine (including, without limitation, latent and other defects, whether or not discoverable, and any claim for patent, trademark or copyright infringement), or in any way relating to or arising out of the administration of the Trust Indenture Estate or the action or inaction of the Indenture Trustee hereunder, except only (i) in the case of willful misconduct or gross negligence (or negligence in the case of handling of funds) of the Indenture Trustee in the performance of its duties hereunder, (ii) as may result from the inaccuracy of any representation or warranty of the Indenture Trustee made in the Refunding Agreement, (iii) as otherwise provided in Section 2.04(a) hereof or in the last sentence of Section 5.04 hereof or (iv) as otherwise excluded by the terms of Sections 10(b) and 13 of the Lease from the Lessee's indemnities to the Indenture Trustee, in its individual capacity and as Indenture Trustee, and its successors, permitted assigns, agents and servants thereunder; provided that so long as the Lease is in effect, the Indenture Trustee shall not make any claim under this Section 7.01 for any amount indemnified against by the Lessee under the Lease without first (but only to the extent not stayed or otherwise prevented by operation of law) making demand on the Lessee for payment of such amount. The Indenture Trustee shall notify the Owner Trustee and the Lessee promptly of any claim for which it may seek indemnity. The Lessee shall be entitled to defend any claim by the Indenture Trustee to the extent provided in Section 10 or 13 of the Lease. The Indenture Trustee shall be entitled to indemnification from the Trust Indenture Estate for any liability, obligation, loss, damage, penalty, claim, action, suit, cost, expense or disbursement indemnified against pursuant to this Section 7.01 to the extent not reimbursed by the Lessee or others, but without releasing any of them from their respective agreements of reimbursement; and to secure the same the Indenture Trustee shall have a prior Lien on the Trust Indenture Estate. The indemnities contained in this Section 7.01 shall survive the termination of this Indenture. SECTION 7.02. Exculpation and Release of Liability. Without in any way affecting the limitations on liability set forth in the Operative Documents, the Indenture Trustee, and each Note Holder by accepting any Equipment Note hereunder, hereby acknowledge and agree that none of the Trust Company, the Owner Participant or any director, officer, employee, stockholder, agent or affiliate of the Trust Company or the Owner Participant (the "Exculpated Equity Persons") shall have any obligation, duty or liability of any kind whatsoever to the Indenture Trustee or Trust Indenture 81 - 76 - any such Note Holder in connection with the exercise by any Exculpated Equity Person of any rights of the Owner Trustee or the taking of any action or the failure to take any action by any Exculpated Equity Person in connection with any rights of the Owner Trustee under this Indenture or the Lease, and each such Note Holder hereby waives and releases, to the extent permitted by applicable law, each Exculpated Equity Person of any and all such obligations, duties or liabilities. ARTICLE VIII SUCCESSOR TRUSTEES AND SEPARATE TRUSTEES SECTION 8.01. Notice of Successor Owner Trustee. In the case of any appointment of a successor to the Owner Trustee pursuant to the Trust Agreement or any merger, conversion, consolidation or sale of substantially all of the corporate trust business of the Trust Company pursuant to the Trust Agreement, the successor Owner Trustee shall give prompt written notice thereof to the Indenture Trustee and to each Note Holder. SECTION 8.02. Resignation and Removal of Indenture Trustee; Appointment of Successor. (a) The Indenture Trustee or any successor thereto may resign at any time without cause by giving at least 30 calendar days' prior written notice to the Owner Trustee, the Owner Participant, each Note Holder and the Lessee, 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 remove the Indenture Trustee without cause by an instrument in writing delivered to the Owner Trustee, the Lessee 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, with the consent of the Lessee, a successor Indenture Trustee by an instrument signed by such Holders (whose fees shall be reasonably acceptable to the Lessee). If a successor Indenture Trustee shall not have been appointed within 30 calendar days after such notice of resignation or removal, the Indenture Trustee, any Note Holder, the Owner Trustee, the Lessee or the Owner Participant 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 within one year from the date of the appointment by such court. Trust Indenture 82 - 77 - (b) Any successor Indenture Trustee, however appointed, shall execute and deliver to the Owner Trustee and to the predecessor Indenture Trustee an instrument accepting and assuming such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Indenture Trustee, without further act, shall become vested with and bound by all the estates, properties, rights, powers, duties and obligations of the predecessor Indenture Trustee hereunder and under the other Indenture Documents in the trusts 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 moneys or other property then held by such predecessor Indenture Trustee hereunder, subject nevertheless to its claim provided for in Section 6.07 hereof. (c) Any successor Indenture Trustee, however appointed, shall be a bank or trust company having a combined capital and surplus of at least $200,000,000 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 8.02, be the Indenture Trustee under this Indenture without further act. Notwithstanding the foregoing, upon the request of the Owner Trustee or the Lessee, any such successor corporation referred to in this Section 8.02(d) shall deliver to the Owner Trustee and the Lessee an instrument confirming its status as the Indenture Trustee hereunder and under the other Indenture Documents. SECTION 8.03. Appointment of Separate Trustees. (a) At any time or times, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Indenture Estate may at the time be located or in which any action of the Indenture Trustee may be required to be performed or taken, the Indenture Trustee, by an instrument in writing signed by it, may appoint one or more individuals or corporations to act as separate trustee or separate trustees or co-trustee, Trust Indenture 83 - 78 - acting jointly with the Indenture Trustee, of all or any part of the Trust Indenture Estate to the full extent that local law makes it necessary for such separate trustee or separate trustees or co-trustee acting jointly with the Indenture Trustee to act. (b) The Indenture Trustee and, at the request of the Indenture Trustee, the Owner Trustee, shall execute, acknowledge and deliver all such instruments as may be required by the legal requirements of any jurisdiction or by any such separate trustee or separate trustees or co-trustee for the purpose of more fully confirming such title, rights or duties to such separate trustee or separate trustees or co-trustee. Upon the acceptance in writing of such appointment by any such separate trustee or separate trustees or co-trustee, it, he, she or they shall be vested with such title to the Trust Indenture Estate or any part thereof, and with such rights and duties, as shall be specified in the instrument of appointment, jointly with the Indenture Trustee (except insofar as local law makes it necessary for any such separate trustee or separate trustees to act alone) subject to all the terms of this Indenture. Any separate trustee or separate trustees or co-trustee may, at any time by an instrument in writing, constitute the Indenture Trustee its, his or her attorney-in-fact and agent with full power and authority to do all acts and things and to exercise all discretion on its, his or her behalf and in its, his or her name.
