If such a record date is fixed, such Direction may be given before or after such record date, but only the Certificateholders of record at the close of business on such record date shall be deemed to be Certificateholders for the purposes of determining whether Certificateholders of the requisite proportion of Outstanding Certificates have authorized or agreed or consented to such Direction, and for that purpose the Outstanding Certificates shall be computed as of such record date; provided that no 21 -16- such Direction by the Certificateholders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Agreement not later than one year after such record date. (f) Any Direction by the Holder of any Certificate shall bind the Holder of every Certificate issued upon the transfer thereof or in exchange therefor or in lieu thereof, whether or not notation of such Direction is made upon such Certificate. (g) Except as otherwise provided in Section 1.04(c), Certificates owned by or pledged to any Person shall have an equal and proportionate benefit under the provisions of this Agreement, without preference, priority, or distinction as among all of the Certificates. ARTICLE II ORIGINAL ISSUANCE OF CERTIFICATES; ACQUISITION OF EQUIPMENT NOTES Section 2.01. Issuance of Certificates; Acquisition of Equipment Notes. (a) The Trustee is hereby directed (i) to execute and deliver the Intercreditor Agreement, the Registration Rights Agreement, the Escrow Agreement and the Note Purchase Agreement on or prior to the Issuance Date, each in the form delivered to the Trustee by the Company and (ii) subject to the respective terms thereof, to perform its obligations thereunder. Upon request of the Company and the satisfaction or waiver of the closing conditions specified in the Certificate Purchase Agreement, the Trustee shall execute, deliver, authenticate, issue and sell Certificates in authorized denominations equaling in the aggregate the amount set forth, with respect to the Trust, in Schedule II to the Certificate Purchase Agreement evidencing the entire ownership interest in the Trust, which amount equals the maximum aggregate principal amount of Equipment Notes which may be purchased by the Trustee pursuant to the Note Purchase Agreement. Except as provided in Sections 3.04, 3.05, 3.06, 3.07 and 3.10 hereof, the Trustee shall not execute, authenticate or deliver Certificates in excess of the aggregate amount specified in this paragraph. (b) On or after the Issuance Date, the Company may deliver from time to time to the Trustee a Delivery Notice relating to one or more Equipment Notes. After receipt of a Delivery Notice and in any case no later than one Business Day prior to a Delivery Date as to which such Delivery Notice relates (the "Applicable Delivery Date") (or, if the Issuance Date is an Applicable Delivery Date, on the Issuance Date), the Trustee shall (as and when specified in the Delivery Notice) instruct the Escrow Agent to provide a Notice of Purchase Withdrawal to the Depositary requesting (A) the withdrawal of one or more Deposits on the Applicable Delivery Date in accordance with and to the extent permitted by the terms of the Escrow Agreement and the Deposit Agreement and (B) the payment of all, or a portion, of such Deposit or Deposits in an amount equal in the aggregate to the purchase price of such Equipment Notes to or on behalf of the Owner Trustee or the Company, as the case may be, issuing such Equipment Notes, all as shall be described in the Delivery Notice; provided that, if the Issuance Date is an Applicable Delivery Date, such purchase price shall be paid from a portion of the proceeds of the sale of the Certificates. The Trustee shall (as and when specified in such Delivery Notice), subject to the conditions set forth in Section 2 of the Note Purchase 22 -17- Agreement, enter into and perform its obligations under the Participation Agreement specified in such Delivery Notice (the "Applicable Participation Agreement") and cause such certificates, documents and legal opinions relating to the Trustee to be duly delivered as required by the Applicable Participation Agreement. If at any time prior to the Applicable Delivery Date, the Trustee receives a notice of postponement pursuant to Section 2(e) or 2(f) of the Note Purchase Agreement, then the Trustee shall give the Depositary (with a copy to the Escrow Agent) a notice of cancellation of such Notice of Purchase Withdrawal relating to such Deposit or Deposits on such Applicable Delivery Date. Upon satisfaction of the conditions specified in the Note Purchase Agreement and the Applicable Participation Agreement, the Trustee shall purchase the applicable Equipment Notes with the proceeds of the withdrawals of one or more Deposits made on the Applicable Delivery Date in accordance with the terms of the Deposit Agreement and the Escrow Agreement (or, if the Issuance Date is the Applicable Delivery Date with respect to such Applicable Participation Agreement, from a portion of the proceeds of the sale of the Certificates). The purchase price of such Equipment Notes shall equal the principal amount of such Equipment Notes. Amounts withdrawn from such Deposit or Deposits in excess of the purchase price of the Equipment Notes or to the extent not applied on the Applicable Delivery Date to the purchase price of the Equipment Notes, shall be re-deposited by the Trustee with the Depositary on the Applicable Delivery Date in accordance with the terms of the Deposit Agreement. Section 2.02. Withdrawal of Deposits. If any Deposits remain outstanding on the Business Day next succeeding the Cut-Off Date, (i) (A) the Trustee shall give the Escrow Agent notice that the Trustee's obligation to purchase Equipment Notes under the Note Purchase Agreement has terminated and instruct the Escrow Agent to provide a notice of Final Withdrawal to the Depositary substantially in the form of Exhibit B to the Deposit Agreement (the "Final Withdrawal Notice") and (B) the Trustee will make a demand upon the Company under the Note Purchase Agreement for an amount equal to the Special Redemption Premium, if applicable, such payment to be made on the Final Withdrawal Date. Section 2.03. Acceptance by Trustee. The Trustee, upon the execution and delivery of this Agreement, acknowledges its acceptance of all right, title and interest in and to the Trust Property and declares that the Trustee holds and will hold such right, title and interest for the benefit of all then present and future Certificateholders, upon the trusts herein set forth. Subject to Section 7.14, the Trustee shall take all actions reasonably necessary to effect the registration of all such Equipment Notes in the name of the Subordination Agent. By its payment for and acceptance of each Certificate issued to it under this Agreement, each initial Certificateholder as grantor of the Trust thereby joins in the creation and declaration of the Trust. Section 2.04. Limitation of Powers. The Trust is constituted solely for the purpose of making the investment in the Equipment Notes, and, except as set forth herein, the Trustee shall not be authorized or empowered to acquire any other investments or engage in any other activities including without limitation purchasing any Equipment Note issued in connection with the redemption of outstanding Equipment Notes under any Indenture and, in particular, the Trustee shall not be authorized or empowered to do anything that would cause such Trust to fail to qualify as a "grantor trust" for federal income tax purposes (including as subject to this restriction, acquiring any Aircraft (as defined in the respective Indentures) by bidding such 23 -18- Equipment Notes or otherwise, or taking any action with respect to any such Aircraft once acquired).

AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION", "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT. THE PASS THROUGH TRUST AGREEMENT CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS CERTIFICATE IN VIOLATION OF THE FOREGOING RESTRICTIONS. Each Global Certificate shall bear the following legend on the face thereof: UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE TRUSTEE OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IN EXCHANGE FOR THIS CERTIFICATE IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. TRANSFERS OF THIS GLOBAL CERTIFICATE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL CERTIFICATE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN SECTIONS 3.05 AND 3.06 OF THE PASS THROUGH TRUST AGREEMENT REFERRED TO HEREIN. Section 3.03. Authentication of Certificates. (a) On the Issuance Date, the Trustee shall duly execute, authenticate and deliver Certificates in authorized denominations equaling in the aggregate the amount set forth, with respect to the Trust, in Schedule II to the Certificate Purchase Agreement, evidencing the entire ownership of the Trust, which amount equals the maximum aggregate principal amount of Equipment Notes which may be purchased by the Trustee pursuant to the Note Purchase Agreement. (b) No Certificate shall be entitled to any benefit under this Agreement or be valid or obligatory for any purpose, unless there appears on such Certificate a certificate of authentication substantially in the form provided for herein executed by the Trustee by the manual signature of one of its authorized signatories, and such certificate upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. 27 -22- (c) Certificates bearing the manual or facsimile signature of an individual who was, at the time when such signature was affixed, authorized to sign on behalf of the Trustee shall be valid and binding obligations of the Trust notwithstanding that such individual has ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such office on the date of such Certificates. Section 3.04. Transfer and Exchange. The Trustee shall cause to be kept at the office or agency to be maintained by it in accordance with the provisions of Section 7.12 a register (the "Register") of the Certificates in which, subject to such reasonable regulations as it may prescribe, the Trustee shall provide for the registration of such Certificates and of transfers and exchanges of such Certificates as herein provided. The Trustee shall initially be the registrar (the "Registrar") for the purpose of registering such Certificates and transfers and exchanges of such Certificates as herein provided. The Company, upon notice to the Trustee, may change the Registrar at any time. All Certificates issued upon any registration of transfer or exchange of Certificates shall be valid obligations of the Trust, evidencing the same interest therein, and entitled to the same benefits under this Trust Agreement, as the Certificates surrendered upon such registration of transfer or exchange. A Certificateholder may transfer a Certificate, or request that a Certificate be exchanged for Certificates in an aggregate Fractional Undivided Interest equal to the Fractional Undivided Interest of such Certificate surrendered for exchange of other authorized denominations, by surrender of such Certificate to the Trustee with the form of transfer notice thereon duly completed and executed, and otherwise complying with the terms of this Agreement, including providing evidence of compliance with any restrictions on transfer, in form satisfactory to the Trustee and the Registrar; provided that no exchanges of Initial Certificates for Exchange Certificates shall occur until an Exchange Offer Registration Statement shall have been declared effective by the SEC (notice of which shall be provided to the Trustee by the Company). No such transfer shall be effected until, and such transferee shall succeed to the rights of a Certificateholder only upon, final acceptance and registration of the transfer by the Registrar in the Register. Prior to the registration of any transfer by a Certificateholder as provided herein, the Trustee shall treat the person in whose name the Certificate is registered as the owner thereof for all purposes, and the Trustee shall not be affected by notice to the contrary. Furthermore, DTC shall, by acceptance of a Global Certificate, agree that transfers of beneficial interests in such Global Certificate may be effected only through a book-entry system maintained by DTC (or its agent) and that ownership of a beneficial interest in the Certificate shall be required to be reflected in a book-entry. When Certificates are presented to the Registrar with a request to register the transfer thereof or to exchange them for other authorized denominations of a Certificate in a Fractional Undivided Interest equal to the aggregate Fractional Undivided Interest of Certificates surrendered for exchange, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met. To permit registrations of transfers and exchanges in accordance with the terms, conditions and restrictions hereof, the Trustee shall execute and authenticate Certificates at the Registrar's request. No service charge shall be made to a Certificateholder for any registration of transfer or exchange of Certificates, but the Trustee shall require payment of a sum sufficient to 28 -23- cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates. All Certificates surrendered for registration of transfer or exchange shall be canceled and subsequently destroyed by the Trustee. Section 3.05. Book-Entry Provisions for Restricted Global Certificates and Regulation S Global Certificates. (a) Members of, or participants in, DTC ("Agent Members") shall have no rights under this Agreement with respect to any Global Certificate held on their behalf by DTC, or the Trustee as its custodian, and DTC may be treated by the Trustee and any agent of the Trustee as the absolute owner of such Global Certificate for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Trustee or any agent of the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or shall impair, as between DTC and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Certificate. Upon the issuance of any Global Certificate, the Registrar or its duly appointed agent shall record DTC as the registered holder of such Global Certificate. (b) Transfers of any Global Certificate shall be limited to transfers of such Restricted Global Certificate or Regulation S Global Certificate in whole, but not in part, to DTC. Beneficial interests in the Restricted Global Certificate and any Regulation S Global Certificate may be transferred in accordance with the rules and procedures of DTC and the provisions of Section 3.06. Beneficial interests in a Restricted Global Certificate or a Regulation S Global Certificate shall be delivered to all beneficial owners thereof in the form of Restricted Definitive Certificates or Regulation S Definitive Certificates, as the case may be, if (i) DTC notifies the Trustee that it is unwilling or unable to continue as depositary for such Restricted Global Certificate or Regulation S Global Certificate, as the case may be, and a successor depositary is not appointed by the Trustee within 90 days of such notice, and (ii) after the occurrence and during the continuance of an Event of Default, owners of beneficial interests in a Global Certificate with Fractional Undivided Interests aggregating not less than a majority in interest in the Trust advise the Trustee, the Company and DTC through Agent Members in writing that the continuation of a book-entry system through DTC or its successor is no longer in their best interests. (c) Any beneficial interest in one of the Global Certificates that is transferred to a Person who takes delivery in the form of an interest in another Global Certificate will, upon such transfer, cease to be an interest in such Global Certificate and become an interest in the other Global Certificate and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Certificate for as long as it remains such an interest. (d) In connection with the transfer of an entire Restricted Global Certificate or an entire Regulation S Global Certificate to the beneficial owners thereof pursuant to paragraph (b) of this Section 3.05, such Restricted Global Certificate or Regulation S Global Certificate, as the case may be, shall be deemed to be surrendered to the Trustee for cancellation, and the Trustee shall execute, authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Restricted Global Certificate or Regulation S Global Certificate, as the case may be, an equal aggregate principal amount of Restricted Definitive Certificates or Regulation S Definitive Certificates, as the case may be, of 29 -24- authorized denominations.

(f) General. By acceptance of any Certificate bearing the Restricted Legend, each Holder of such a Certificate acknowledges the restrictions on transfer of such Certificate set forth in this Agreement and agrees that it will transfer such Certificate only as provided in this Agreement.

In connection with any transfer of Certificates, each Certificateholder agrees by its acceptance of the Certificates to furnish the Registrar 32 -27- or the Trustee such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act and in accordance with the terms and provisions of this Article III; provided that the Registrar shall not be required to determine the sufficiency of any such certifications, legal opinions or other information. Until such time as no Certificates remain Outstanding, the Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 3.05 or this Section 3.06. The Trustee, if not the Registrar at such time, shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar. Section 3.07. Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate is surrendered to the Registrar or the Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to the Registrar and the Trustee such security, indemnity or bond, as may be required by them to save each of them harmless, then, in the absence of notice to the Registrar or the Trustee that such destroyed, lost or stolen Certificate has been acquired by a protected purchaser, and provided that the requirements of Section 8-405 of the Uniform Commercial Code in effect in any applicable jurisdiction are met, the Trustee shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate or Certificates, in authorized denominations and of like Fractional Undivided Interest and bearing a number not contemporaneously outstanding. In connection with the issuance of any new Certificate under this Section 3.07, the Trustee may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee and the Registrar) connected therewith. Any duplicate Certificate issued pursuant to this Section 3.07 shall constitute conclusive evidence of the appropriate Fractional Undivided Interest in the Trust, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates. Section 3.08. Persons Deemed Owners. Prior to due presentment of a Certificate for registration of transfer, the Trustee, the Registrar and any Paying Agent may treat the Person in whose name any Certificate is registered (as of the day of determination) as the owner of such Certificate for the purpose of receiving distributions pursuant to Article IV and for all other purposes whatsoever, and none of the Trustee, the Registrar or any Paying Agent shall be affected by any notice to the contrary. Section 3.09. Cancellation. All Certificates surrendered for payment or transfer or exchange shall, if surrendered to the Trustee or any agent of the Trustee other than the 33 -28- Registrar, be delivered to the Registrar for cancellation and shall promptly be canceled by it.

Until definitive Certificates are ready for delivery, the Trustee shall authenticate temporary Certificates. Temporary Certificates shall be substantially in the form of definitive Certificates but may have insertions, substitutions, omissions and other variations determined to be appropriate by the officers executing the temporary Certificates, as evidenced by their execution of such temporary Certificates. If temporary Certificates are issued, the Trustee will cause definitive Certificates to be prepared without unreasonable delay. After the preparation of definitive Certificates, the temporary Certificates shall be exchangeable for definitive Certificates upon surrender of the temporary Certificates at the office or agency of the Trustee designated for such purpose pursuant to Section 7.12, without charge to the Certificateholder. Upon surrender for cancellation of any one or more temporary Certificates, the Trustee shall execute, authenticate and deliver in exchange therefor a like face amount of definitive Certificates of authorized denominations. Until so exchanged, the temporary Certificates shall be entitled to the same benefits under this Agreement as definitive Certificates. Section 3.11. Limitation of Liability for Payments. All payments and distributions made to Certificateholders in respect of the Certificates shall be made only from the Trust Property and only to the extent that the Trustee shall have sufficient income or proceeds from the Trust Property to make such payments in accordance with the terms of Article IV of this Agreement. Each Certificateholder, by its acceptance of a Certificate, agrees that it will look solely to the income and proceeds from the Trust Property for any payment or distribution due to such Certificateholder pursuant to the terms of this Agreement and that it will not have any recourse to the Company, the Trustee, the Loan Trustees, the Liquidity Provider, the Owner Trustees or the Owner Participants, except as otherwise expressly provided herein or in the Intercreditor Agreement. The Company is a party to this Agreement solely for purposes of meeting the requirements of the Trust Indenture Act, and therefore shall not have any right, obligation or liability hereunder (except as otherwise expressly provided herein). Section 3.12 ERISA Restrictive Legend. All Certificates issued pursuant to this Agreement shall bear a legend to the following effect (the "ERISA Legend") unless the Company and the Trustee determine otherwise consistent with applicable law: "BY ITS ACQUISITION HEREOF, THE HOLDER REPRESENTS THAT (A) NO PLAN ASSETS HAVE BEEN USED TO PURCHASE THIS CERTIFICATE OR AN INTEREST HEREIN OR (B) THE PURCHASE AND HOLDING OF THIS CERTIFICATE OR AN INTEREST HEREIN IS EXEMPT FROM THE PROHIBITED TRANSACTION RESTRICTIONS OF ERISA AND THE CODE PURSUANT TO ONE OR MORE PROHIBITED TRANSACTION STATUTORY OR ADMINISTRATIVE EXEMPTIONS. THE PASS THROUGH TRUST AGREEMENT CONTAINS A PROVISION REQUIRING 34 -29- THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS CERTIFICATE IN VIOLATION OF THE FOREGOING RESTRICTIONS." By acceptance of any Certificate bearing the ERISA Legend, each Holder of such a Certificate acknowledges the restrictions on transfer of such Certificate set forth in this Agreement and agrees that it will transfer such Certificate only as provided in this Agreement. The Trustee shall not register a transfer of any Certificate unless such transfer complies with the restrictions on transfer, if any, of such Certificate set forth in such legend.

Under certain circumstances set forth in Section 11.01 of the Agreement, all of the Trustee's right, title and interest to the Trust Property may be assigned, transferred and delivered to the Related Trustee of the Related Trust pursuant to the Assignment and Assumption Agreement.

Each Certificateholder, by its acceptance of this Certificate or a beneficial interest herein, agrees to be bound by the Assignment and Assumption Agreement and subject to the terms of the Related Pass Through Trust Agreement as a certificateholder thereunder. From and after the Transfer, unless and to the extent the context otherwise requires, references herein to the Trust, the Agreement and the Trustee shall constitute references to the Related Trust, the Related Pass Through Trust Agreement and trustee of the Related Trust, respectively. The Certificates are issuable only as registered Certificates without coupons in minimum denominations of [$100,000]* [$1,000]** Fractional Undivided Interest and integral multiples of $1,000 in excess thereof except that one Certificate may be in a different denomination. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the Trust, as requested by the Certificateholder surrendering the same. No service charge will be made for any such registration of transfer or exchange, but the Trustee shall require payment by the Holder of a sum sufficient to cover any tax or governmental charge payable in connection therewith. Each Certificateholder and Investor, by its acceptance of this Certificate or a beneficial interest herein, agrees to treat the Trust as a grantor trust for all U.S. federal, state and local income tax purposes. The Trustee, the Registrar, and any agent of the Trustee or the Registrar may treat the person in whose name this Certificate is registered as the owner hereof for all purposes, and neither the Trustee, the Registrar, nor any such agent shall be affected by any notice to the contrary. The obligations and responsibilities created by the Agreement and the Trust created thereby shall terminate upon the distribution to Certificateholders of all amounts required to be distributed to them pursuant to the Agreement and the disposition of all property held as part of the Trust Property. - ---------- * To be included only on each Initial Certificate. ** To be included only on each Exchange Certificate. 71 A-7 UNTIL THE TRANSFER, THE AGREEMENT AND THIS CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.
