In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to

other matters and any such Person may certify or give an opinion as to such matters in one or several documents.

     Any Opinion of Counsel stated to be based on the opinion of other counsel shall be accompanied by a copy of such other opinion.

     Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Basic Agreement or any Trust Supplement, they may, but need not, be consolidated and form one instrument.

     Section 1.04. Acts of Certificateholders. (a) Any direction, consent, waiver or other action provided by this Basic Agreement or any Trust Supplement to be given or taken by Certificateholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Certificateholders in person or by an 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 Trustee and, where it is hereby expressly required, to the Company or any Indenture Trustee. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Certificateholders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Basic Agreement or any Trust Supplement and (subject to Section 7.01) conclusive in favor of the Trustee, the Company and the Indenture Trustee, if made in the manner provided in this Section.

     (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the certificate of any notary public or other officer of any jurisdiction authorized to take acknowledgements of deeds or administer oaths that the Person executing such instrument acknowledged to him the execution thereof, or by an affidavit of a witness to such execution sworn to before any such notary or such other officer and where such execution is by an officer of a corporation or association or a member of a partnership, on behalf of such corporation, association or partnership such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other reasonable manner which the Trustee deems sufficient.

     (c) In determining whether the Certificateholders of the requisite Fractional Undivided Interests of Certificates of any series Outstanding have given any direction, consent or waiver (a “Direction”), under this Basic Agreement or any Trust Supplement, Certificates owned by the Company, any related Owner Trustee, any related Owner Participant or any Affiliate of any such Person shall be disregarded and deemed not to be Outstanding for purposes of any such determination. In determining whether the Trustee shall be protected in relying upon any such Direction, only Certificates of such series which the Trustee knows to be so owned shall be so disregarded. Notwithstanding the foregoing, (i) if any such Person owns 100% of the Certificates of any series Outstanding, such Certificates shall not be so disregarded as aforesaid, and (ii) if any amount of Certificates of such series so owned by any such Person have been pledged in good faith, such Certificates shall not be disregarded as aforesaid if the pledgee

establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Certificates and that the pledgee is not the Company, any related Owner Trustee, any related Owner Participant or any Affiliate of any such Persons.

     (d) The Company may at its option by delivery of an Officer’s Certificate to the Trustee set a record date to determine the Certificateholders entitled to give any consent, request, demand, authorization, Direction, notice, waiver or other Act. Notwithstanding Section 316(c) of the Trust Indenture Act, such record date shall be the record date specified in such Officer’s Certificate which shall be a date not more than 30 days prior to the first solicitation of Certificateholders in connection therewith. If such a record date is fixed, such consent, request, demand, authorization, Direction, notice, waiver or other Act may be given before or after such record date, but only the Certificateholders of record of the applicable series 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 of such series have authorized or agreed or consented to such consent, request, demand, authorization, Direction, notice, waiver or other Act, and for that purpose the Outstanding Certificates of such series shall be computed as of such record date; provided that no such consent, request, demand, authorization, Direction, notice, waiver or other Act by the Certificateholders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Basic Agreement not later than one year after such record date.

     (e) Any Direction, consent, waiver or other action by the Certificateholder of any Certificate shall bind the Certificateholder of every Certificate issued upon the transfer thereof or in exchange therefor or in lieu thereof, whether or not notation of such action is made upon such Certificate.

     (f) Except as otherwise provided in Section 1.04(c), Certificates of any series owned by or pledged to any Person shall have an equal and proportionate benefit under the provisions of this Basic Agreement and the related Trust Supplement, without preference, priority, or distinction as among all of the Certificates of such series.

ARTICLE II

     Section 2.01. Amount Unlimited; Issuable in Series. (a) The aggregate principal amount of Certificates which may be authenticated and delivered under this Basic Agreement is unlimited. The Certificates may be issued from time to time in one or more series and shall be designated generally as the “Pass Through Certificates,” with such further designations added or incorporated in such title for the Certificates of each series as specified in the related Trust Supplement. Each Certificate shall bear upon its face the designation so selected for the series to which it belongs. All Certificates of the same series shall be substantially identical except that the Certificates of a series may differ as to denomination and as may otherwise be provided in the Trust Supplement establishing the Certificates of such series. Each separate series of Certificates issued pursuant to this Basic Agreement and related Trust Supplement will evidence Fractional Undivided Interests in the separate Trust formed by such Trust Supplement, and will have no rights, benefits or interests in respect of any other separate Trust or the Trust Property

held therein. All Certificates of the same series issued under this Basic Agreement and the related Trust Supplement shall be in all respects equally and ratably entitled to the benefits of this Basic Agreement and the related Trust Supplement without preference, priority, or distinction on account of the actual time or times of authentication and delivery, all in accordance with the terms and provisions of this Basic Agreement and the related Trust Supplement.

     (b) The following matters shall be established with respect to the Certificates of each series issued hereunder by a Trust Supplement executed and delivered by and between the Company and the Trustee:

     (1) the formation of the Trust as to which the Certificates represent Fractional Undivided Interests and its designation (which designation shall distinguish such Trust from each other Trust created under this Basic Agreement and a Trust Supplement);

     (2) the specific title of the Certificates (which title shall distinguish the Certificates of the series from each other series of Certificates issued under this Basic Agreement);

     (3) any limit upon the aggregate principal amount of the Certificates which may be authenticated and delivered under this Basic Agreement (which limit shall not pertain to Certificates authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Certificates of the series pursuant to Sections 3.03, 3.04 and 3.05);

     (4) the Cut-Off Date with respect to the Certificates and the related Trust;

     (5) the Regular Distribution Dates applicable to the Certificates and the related Trust;

     (6) the Special Distribution Dates applicable to the Certificates and the related Trust;

     (7) if other than as provided in Section 7.12, the Registrar or the Paying Agent for the Certificates of such series, including any Co-Registrar or additional Paying Agent;

     (8) if other than as provided in Section 3.01, the denominations in which the Certificates of such series shall be issuable;

     (9) the specific form of the Certificates of such series and whether or not such Certificates are to be issued as Book-Entry Certificates;

     (10) a description of the Equipment Notes to be acquired and held in the Trust formed by such Trust Supplement and of the related Equipment and Note Documents;

     (11) provisions with respect to the terms for which the definitions set forth in Article I hereof permit or require further specification in the related Trust Supplement; and

     (12) any other terms of the Certificates of such series (which terms shall not be inconsistent with the provisions of the Trust Indenture Act or adversely affect the interest of the Certificateholders of any series Outstanding at the time), including any terms which may be required or advisable under United States laws or regulations or advisable in connection with the marketing of Certificates of the series.

     (c) At any time and from time to time after the execution and delivery of this Basic Agreement and a Trust Supplement forming a Trust and establishing the terms of Certificates of a series, Certificates of such series shall be executed, authenticated and delivered by the Trustee to the Person or Persons specified by the Company upon request of the Company and upon satisfaction of any conditions precedent set forth in the related Trust Supplement.

     Section 2.02. Acquisition of Equipment Notes. (a) Certificates of a series executed, authenticated and delivered by the Trustee upon request of the Company in accordance with Section 2.01(c) shall equal in the aggregate the aggregate principal amount of the Equipment Notes to be purchased by the Trustee pursuant to the related Participation Agreements and shall evidence the entire ownership of the related Trust. The Trustee shall issue and sell such Certificates, in authorized denominations and in such Fractional Undivided Interests, so as to result in the receipt of consideration in an amount equal to the aggregate principal amount of such Equipment Notes and, concurrently therewith, the Trustee shall purchase, pursuant to the terms and conditions of the Participation Agreements, the Equipment Notes (except Postponed Notes, if any) at a purchase price equal to the amount of such consideration so received. Except as provided in Sections 3.03, 3.04 and 3.05 hereof, the Trustee shall not execute, authenticate or deliver Certificates of such series in excess of the aggregate amount specified in this paragraph. The provisions of this Subsection (a) are subject to the provisions of Subsection (b) below.

     (b) If on or prior to the Issuance Date with respect to a series of Certificates and the related Trust the Company shall deliver to the Trustee a Postponement Notice relating to one or more Postponed Notes, the Trustee shall postpone the purchase of the related Postponed Notes and shall deposit into an escrow account (the “Escrow Account”) to be maintained as a part of such Trust an amount equal to the purchase price of such Postponed Notes (the “Escrowed Funds”). The Escrowed Funds so deposited shall be invested by the Trustee at the direction and risk of, and for the benefit of, the Company in Specified Investments (i) maturing no later than any scheduled Transfer Date relating to such series of Certificates, or (ii) if no such Transfer Date has been scheduled, maturing on the next Business Day, or (iii) if the Company has given notice to the Trustee that any Postponed Notes will not be issued, with respect to the portion of the Escrowed Funds relating to such Postponed Notes, maturing on the next applicable Special Distribution Date, if such investments are reasonably available for purchase. The Trustee shall make withdrawals from the Escrow Account only as provided in this Basic Agreement and the related Trust Supplement.

     Upon request of the Company on one or more occasions, and the satisfaction of the closing conditions specified in the applicable Participation Agreements on or prior to the related Cut-Off Date, the Trustee shall purchase the applicable Postponed Notes with the Escrowed Funds. The purchase price shall equal the principal amount of such Postponed Notes. On the Initial Regular Distribution Date, the Company will pay (in immediately available funds) to the Trustee an amount equal to the interest that would have accrued on any Postponed Notes

purchased after the Issuance Date if such Postponed Notes had been purchased on the Issuance Date, from the Issuance Date to, but not including, the date of the purchase of such Postponed Notes by the Trustee.

     The Trustee shall hold all such Specified Investments until the maturity thereof and will not sell or otherwise transfer such Specified Investments. If Specified Investments held in the Escrow Account mature prior to any applicable Transfer Date, any proceeds received on the maturity of such Specified Investments (other than any earnings thereon) shall be reinvested by the Trustee at the direction and risk of, and for the benefit of, the Company in Specified Investments maturing as provided in the second preceding paragraph.

     Any earnings on Specified Investments received from time to time by the Trustee shall be promptly distributed to the Company. The Company shall pay to the Trustee for deposit to the Escrow Account an amount equal to any losses realized on such Specified Investments.

     If the Company notifies the Trustee prior to the applicable Cut-Off Date that any of the Postponed Notes will not be issued on or prior to the Cut-Off Date for any reason, on the next Special Distribution Date for the series of Certificates related to such Postponed Notes occurring more than 10 days following the date of such notice (i) the Company shall pay to the Trustee for deposit in the related Special Payments Account, in immediately available funds, an amount equal to the interest that would have accrued on the Postponed Notes designated in such notice at a rate equal to the interest rate applicable to such series of Certificates from the Issuance Date to, but not including, such Special Distribution Date and (ii) the Trustee shall transfer an amount equal to that amount of Escrowed Funds that would have been used to purchase the Postponed Notes designated in such notice and the amount paid by the Company pursuant to the immediately preceding clause (i) to the related Special Payments Account for distribution as a Special Payment in accordance with the provisions hereof.

     If, on the applicable Cut-Off Date, an amount equal to less than all of the Escrowed Funds (other than Escrowed Funds referred to in the immediately preceding paragraph) has been used to purchase Postponed Notes, on the Special Distribution Date for the series of Certificates related to such Postponed Notes next following such Cut-Off Date by more than 10 days (i) the Company shall pay to the Trustee for deposit in the related Special Payments Account, in immediately available funds, an amount equal to the interest that would have accrued on such Postponed Notes contemplated to be purchased with such unused Escrowed Funds (other than Escrowed Funds referred to in the immediately preceding paragraph) but not so purchased at a rate equal to the interest rate applicable to such series of Certificates from the Issuance Date to, but no including, such Special Distribution Date and (ii) the Trustee shall transfer such unused Escrowed Funds and the amount paid by the Company pursuant to the immediately preceding clause (i) to such Special Payments Account for distribution as a Special Payment in accordance with the provisions hereof.

     Section 2.03. Acceptance by Trustee. The Trustee, upon the execution and delivery of a Trust Supplement creating a Trust and a series of Certificates, shall acknowledge its acceptance of all right, title and interest in and to the Equipment Notes to be acquired pursuant to Section 2.02 hereof and the Participation Agreements and shall declare that the Trustee holds and will hold such right, title, and interest, together with all other property constituting the Trust Property,

for the benefit of all present and future Certificateholders of such series, upon the trusts herein and in such Trust Supplement set forth. By its payment for and acceptance of each Certificate of such series issued to it under this Basic Agreement and such Trust Supplement, each initial Certificateholder of such series as grantor of the Trust thereby joins in the creation and declaration of such Trust.

     Section 2.04. Limitation of Powers. Each Trust shall be constituted solely for the purpose of making the investment in the Equipment Notes provided for in the related Trust Supplement, and, except as set forth herein or in such Trust Supplement, the Trustee shall not be authorized or empowered to acquire any other investments or engage in any other activities and, in particular, the Trustee shall not be authorized or empowered to do anything that would cause the Trust to fail to qualify as a “grantor trust” for federal income tax purposes (including, as subject to this restriction, acquiring any Equipment (as defined in the related Indenture) by bidding the Equipment Notes or otherwise, or taking any action with respect to any such Equipment once acquired).

ARTICLE III

     Section 3.01. Form, Denomination and Execution of Certificates. The Certificates of each series shall be issued in registered form without coupons and shall be substantially in the form attached hereto as Exhibit A, with such omissions, variations and insertions as are permitted by this Basic Agreement or the related Trust Supplement, and may have such letters, numbers or other marks of identification and such legends or endorsements printed, lithographed or engraved thereon, as may be required to comply with the rules of any securities exchange on which such Certificates may be listed or to conform to any usage in respect thereof, or as may, consistently herewith, be prescribed by the Trustee or by the officer executing such Certificates, such determination by said officer to be evidenced by his signing such Certificates.

     Except as provided in Section 3.09, the definitive Certificates of such series shall be printed, lithographed or engraved or produced by any combination of these methods or may be produced in any other manner permitted by the rules of any securities exchange on which such Certificates may be listed, all as determined by the officer executing such Certificates, as evidenced by his execution of such Certificates.

     Except as otherwise provided in the related Trust Supplement, the Certificates of each series shall be issued in denominations of $1,000 or integral multiples thereof except that one Certificate of such series may be issued in a denomination of less than $1,000.

     The Certificates of each series shall be executed on behalf of the Trustee by manual or facsimile signature of a Responsible Officer of the Trustee. 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 Trustee, 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 at the date of such Certificates. No Certificate of any series shall be entitled to any benefit under this Basic Agreement or any Trust Supplement, or be valid for any purposes, unless there appears on such Certificate a certificate of

authentication substantially in the form set forth in Exhibit A hereto executed by the Trustee by manual signature, and such certificate upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates of any series shall be dated the date of their authentication.

     Section 3.02. Authentication of Certificates. The Trustee shall duly authenticate and deliver Certificates of each series in authorized denominations equalling in the aggregate the aggregate principal amount of the Equipment Notes to be purchased by the Trustee pursuant to the related Participation Agreement, and evidencing the entire ownership of the related Trust.

     Section 3.03. Temporary Certificates. Pending the preparation of definitive Certificates of any series, the Trustee may execute, authenticate and deliver temporary Certificates of such series which are printed lithographed, typewritten, or otherwise produced, in any denomination, containing substantially the same terms and provisions as set forth in Exhibit A, except for such appropriate insertions, omissions, substitutions and other variations relating to their temporary nature as the officer executing such temporary Certificates may determine, as evidenced by his execution of such temporary Certificates.

     If temporary Certificates of any series are issued, the Trustee will cause definitive Certificates of such series to be prepared without unreasonable delay. After the preparation of definitive Certificates, the temporary Certificates shall be exchangeable for definitive Certificates of such series upon surrender of the temporary Certificates at the Corporate Trust Office of the Trustee, or at the office or agency of the Trustee maintained in accordance with Section 7.12, without charge to the holder. Upon surrender for cancellation of any one or more temporary Certificates, the Trustee shall execute, authenticate and deliver in exchange therefor definitive Certificates of like series, in authorized denominations of a like aggregate Fractional Undivided Interest. Until so exchanged, such temporary Certificates shall in all respects be entitled to the same benefits under this Basic Agreement and the related Trust Supplement as definitive Certificates of such series.

     Section 3.04. Registration of Transfer and Exchange of Certificates. (a) 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”) for each series of Certificates in which, subject to the provisions of this Section 3.04 and the Certificates, the Trustee shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. The Trustee shall initially be the registrar (the “Registrar”) for the purpose of registering Certificates of each series and transfers and exchanges of Certificates as herein provided.

     (b) Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office or such other office or agency, the Trustee shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates of like series, in authorized denominations of a like aggregate Fractional Undivided Interest. At the option of a Certificateholder, Certificates may be exchanged for other Certificates of like series, in authorized denominations of a like aggregate Fractional Undivided Interest, upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, authenticate and deliver the Certificates that the Certificateholder making the exchange is entitled to receive. Every Certificate presented or

surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Registrar duly executed by the Holder thereof or his attorney duly authorized in writing.

     (c) 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 cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

     (d) All Certificates surrendered for registration of transfer and exchange shall be cancelled and subsequently destroyed by the Trustee.

     Section 3.05. 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 Certificate has been acquired by a bona fide purchaser, 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 of like series and of like Fractional Undivided Interest with the same final Regular Distribution Date. In connection with the issuance of any new Certificate under this Section 3.05, the Trustee shall 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 3.05 shall constitute conclusive evidence of the appropriate Fractional Undivided Interest in the related Trust, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

     Section 3.06. Persons Deemed Owners. Prior to due presentation of a Certificate for registration of transfer, the Trustee, the Registrar, and any Paying Agent of the Trustee may treat the person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 4.02 and for all other purposes whatsoever, and neither the Trustee, the Registrar, nor any Paying Agent of the Trustee shall be affected by any notice to the contrary.

     Section 3.07. Cancellation. All Certificates surrendered for payment or transfer or exchange shall, if surrendered to any Person a party hereto other than the Registrar, be delivered by such Person to the Registrar for cancellation. No Certificates shall be authenticated in lieu of or in exchange for any Certificates cancelled as provided in this Section, except as expressly permitted by this Basic Agreement. All cancelled Certificates held by the Registrar shall be destroyed and a certification of their destruction delivered to the Trustee.

     Section 3.08. Limitation of Liability for Payments. All payments or distributions made to Certificateholders of any series under this Basic Agreement or the related Trust Supplement shall be made only from such Trust Property of the related Trust 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 Basic Agreement and the

related Trust Supplement. Each Certificateholder, by its acceptance of such Certificate, agrees that it will look solely to the income and proceeds from the Trust Property of the related Trust to the extent available for distribution to the Holder thereof as provided in this Basic Agreement and the related Trust Supplement. Nothing in this Basic Agreement shall be construed as an agreement, or otherwise creating an obligation, of the Company to pay any of the principal, premium, if any, and interest due from time to time under the Equipment Notes or in respect of the Certificates.

     Section 3.09. Book-Entry and Definitive Certificates. (a) Except for one Certificate of each series that may be issued in a denomination of less than $1,000, the Certificates of each series may be issued in the form of one or more typewritten Certificates representing the Book-Entry Certificates of such series, to be delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Company. In such case, the Certificates of such series delivered to DTC shall initially be registered on the Register in the name of CEDE & Co., the nominee of the initial Clearing Agency, and no Certificate Owner will receive a definitive certificate representing such Certificate Owner’s interest in the Certificates of such series, except as provided above and in Subsection (d) below. Except with respect to the one Certificate of each series that may be issued in a denomination of less than $1,000, unless and until definitive, fully registered Certificates of such series (the “Definitive Certificates”) have been issued pursuant to Subsection (d) below:

     (i) the provisions of this Section 3.09 shall be in full force and effect;

     (ii) the Company, the Paying Agent, the Registrar and the Trustee may deal with the Clearing Agency for all purposes (including the making of distributions on the Certificates) as the authorized representative of the Certificate Owners;

     (iii) to the extent that the provisions of this Section 3.09 conflict with any other provisions of this Basic Agreement or any Trust Supplement (other than the provisions of any Trust Supplement amending this Section 3.09 as permitted by this Basic Agreement), the provisions of this Section 3.09 shall control;

     (iv) the rights of Certificate Owners shall be exercised only through the Clearing Agency and shall be limited to those established by law and agreements between such Certificate Owners and the Clearing Agency Participants; and until Definitive Certificates are issued pursuant to Subsection (d) below, the Clearing Agency will make book-entry transfers among the Clearing Agency Participants and receive and transmit distributions of principal and interest and premium, if any, on the Certificates to such Clearing Agency Participants; and

     (v) whenever this Basic Agreement or any Trust Supplement requires or permits actions to be taken based upon instructions or directions of Certificateholders of such series holding Certificates of such series evidencing a specified percentage of the Fractional Undivided Interests in the related Trust, the Clearing Agency shall be deemed to represent such percentage only to the extent that it has received instructions to such effect from Certificate Owners and/or Clearing Agency Participants owning or representing, respectively, such required percentage of the beneficial interest in

Certificates of such series and has delivered such instructions to the Trustee. The Trustee shall have no obligation to determine whether the Clearing Agency has in fact received any such instructions.

     (b) Except with respect to the one Certificate of each series that may be issued in a denomination of less than $1,000, whenever notice or other communication to the Certificateholders of such series is required under this Basic Agreement or the related Trust Supplement, unless and until Definitive Certificates shall have been issued pursuant to Subsection (d) below, the Trustee shall give all such notices and communications specified herein to be given to Certificateholders of such series to the Clearing Agency and/or the Clearing Agency Participants, and shall make available additional copies as requested by such Clearing Agency Participants.

     (c) Unless and until Definitive Certificates of a series are issued pursuant to Subsection (d) below, on the Record Date prior to each applicable Regular Distribution Date and Special Distribution Date, the Trustee will request from DTC a Securities Position Listing (as defined in the Letter of Representations) setting forth the names of all Clearing Agency Participants reflected on DTC’s books as holding interests in the Certificates of such series on such Record Date. The Trustee shall mail to each such Clearing Agency Participant, the statements described in Section 4.03 hereof and will make available additional copies as requested by such Clearing Agency Participant to be available for forwarding to Certificate Owners.

     (d) If with respect to the Certificates of any series, (i) the Company advises the Trustee in writing that the Clearing Agency is no longer willing or able to properly discharge its responsibilities and the Trustee or the Company is unable to locate a qualified successor, (ii) the Company at its option, advises the Trustee in writing that it elects to terminate the book-entry system through the Clearing Agency or (iii) after the occurrence of an Event of Default, Certificate Owners of Book-Entry Certificates of such series evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the related Trust, by Act of said Certificate Owners delivered to the Company and the Trustee, advise the Trustee and the Clearing Agency through the Clearing Agency Participants in writing that the continuation of a book-entry system through the Clearing Agency is no longer in the best interests of the Certificate Owners of such series, then the Trustee shall notify all Certificate Owners of such series, through the Clearing Agency, of the occurrence of any such event and of the availability of Definitive Certificates. Upon surrender to the Trustee of all the Certificates of such series held by the Clearing Agency, accompanied by registration instructions from the Clearing Agency for registration of Definitive Certificates in the names of Certificate Owners of such series, the Trustee shall issue and deliver the Definitive Certificates of such series in accordance with the instructions of the Clearing Agency. Neither the Company, the Registrar, the Paying Agent nor the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such registration instructions. Upon the issuance of Definitive Certificates of such series, the Trustee shall recognize the Person in whose name such Definitive Certificates are registered in the Register as Certificateholders of such series hereunder. Neither the Company nor the Trustee shall be liable if the Trustee or the Company is unable to locate a qualified successor Clearing Agency.

     (e) Except as otherwise provided in the related Trust Supplement, the Trustee shall enter into the applicable Letter of Representations with respect to each series of Certificates and fulfill its responsibilities thereunder.

     (f) The provisions of this Section 3.09 may be made inapplicable to any series or may be amended with respect to any series in the related Trust Supplement.

ARTICLE IV

     Section 4.01. Certificate Account and Special Payments Account. (a) The Trustee shall establish and maintain on behalf of the Certificateholders of each series a Certificate Account as one or more non-interest-bearing accounts. The Trustee shall hold the Certificate Account in trust for the benefit of the Certificateholders of such series, and shall make or permit withdrawals therefrom only as provided in this Basic Agreement or the related Trust Supplement. On each day when a Scheduled Payment is made under any Indenture to the Trustee, as holder of the Equipment Notes issued under such Indenture, the Trustee upon receipt shall immediately deposit the aggregate amount of such Scheduled Payment in the applicable Certificate Account.

     (b) The Trustee shall establish and maintain on behalf of the Certificateholders of each series a Special Payments Account as one or more accounts, which shall be non-interest-bearing except as provided in Section 4.04. The Trustee shall hold such Special Payments Account in trust for the benefit of the Certificateholders of such series, and shall make or permit withdrawals therefrom only as provided in this Basic Agreement or the related Trust Supplement. On each day when one or more Special Payments (other than a Special Payment that represents either payment received with respect to an Equipment Note upon an Event of Default in respect thereof or the proceeds of any sale pursuant to Article VI hereof by the Trustee of an Equipment Note) is made under any Indenture to the Trustee, as holder of the Equipment Notes issued under such Indenture, the Trustee upon receipt shall immediately deposit the aggregate amounts of such Special Payments in the applicable Special Payments Account. Upon the sale of any Equipment Note by the Trustee pursuant to Article VI hereof and the realization of any proceeds thereof, the Trustee shall deposit the aggregate amount of such proceeds as a Special Payment in the applicable Special Payments Account.

     (c) The Trustee shall present to the Indenture Trustee to which an Equipment Note relates such Equipment Note on the date of its stated final maturity, or in the case of any Equipment Note which is to be prepaid or purchased in whole pursuant to the relevant Indenture, on the applicable prepayment or purchase date under such Indenture.

     Section 4.02. Distributions from Certificate Account and Special Payments Account. (a) On each Regular Distribution Date with respect to a series of Certificates or as soon thereafter as the Trustee has confirmed receipt of the payment of the Scheduled Payments due on the Equipment Notes held in the related Trust on such date, the Trustee shall distribute out of the applicable Certificate Account the entire amount deposited therein on account of Scheduled Payments pursuant to Section 4.01(a). There shall be so distributed to each Certificateholder of

record on the Record Date with respect to such Regular Distribution Date (other than as provided in Section 11.01 concerning the final distribution) (i) by check mailed to such Certificateholder at the address appearing in the Register or (ii) prior to the time Definitive Certificates are issued, by wire transfer of same-day funds to the account designated by the Certificateholder to the Trustee on or prior to the Record Date relating to such Regular Distribution Date, such Certificateholder’s pro rata share (based on the aggregate Fractional Undivided Interest in the related Trust held by such Certificateholder) of the aggregate amount in the applicable Certificate Account.

     (b) On each Special Distribution Date with respect to any Special Payment with respect to a series of Certificates or as soon thereafter as the Trustee has confirmed receipt of the Special Payments due on the Equipment Notes held in the related Trust or realized upon the sale of any such Equipment Note, the Trustee shall distribute out of the applicable Special Payments Account the entire amount deposited therein on account of Special Payments pursuant to Section 4.01(b). There shall be so distributed to each Certificateholder of record of such series on the Record Date with respect to such Special Distribution Date (other than as provided in Section 11.01 concerning the final distribution) (i) by check mailed to such Certificateholder at the address appearing in the Register or (ii) prior to the time Definitive Certificates are issued, by wire transfer of same-day funds to the account designated by the Certificateholder to the Trustee on or prior to the Record Date relating to such Special Distribution Date, such Certificateholder’s pro rata share (based on the aggregate Fractional Undivided Interest in the related Trust held by such Certificateholder) of the aggregate amount in the applicable Special Payments Account on account of such Special Payment.

     (c) The Trustee shall at the expense of the Company cause notice of each Special Payment with respect to a series of Certificates to be mailed to each Certificateholder of such series at his address as it appears in the Register. In the event of a prepayment or purchase of Equipment Notes held in the related Trust, such notice shall be mailed not less than 20 days prior to the date any such Special Payment is scheduled to be distributed. In the case of a Special Payment pursuant to either of the last two paragraphs of Section 2.02(b), such notice shall be mailed not less than 10 days prior to the date any such Special Payment is scheduled to be distributed. In the case of any other Special Payments, such notice shall be mailed as soon as practicable after the Trustee has confirmed that it has received funds for such Special Payment. Notices mailed by the Trustee shall set forth:

     (i) the Special Distribution Date and the Record Date therefor (except as otherwise provided in Section 11.01);

     (ii) the amount of the Special Payment for each $1,000 face amount Certificate (taking into account any payment to be made by the Company pursuant to Section 2.02(b)) and the amount thereof constituting principal, premium, if any, and interest;

     (iii) the reason for the Special Payment; and

     (iv) if the Special Distribution Date is the same date as a Regular Distribution Date for the Certificates of such series, the total amount to be received on such date for each $1,000 face amount Certificate.

     If the amount of premium payable upon the prepayment or purchase of an Equipment Note has not been calculated at the time that the Trustee mails notice of a Special Payment, it shall be sufficient if the notice sets forth the other amounts to be distributed and states that any premium received will also be distributed.

     Section 4.03. Statements to Certificateholders. (a) On each Regular Distribution Date and Special Distribution Date, if any, with respect to a series of Certificates the Trustee will include with each distribution to Certificateholders of the related series a statement, giving effect to such distribution to be made on such Regular Distribution Date or Special Distribution Date, as the case may be, setting forth the following information (per a $1,000 face amount Certificate as to (i) and (ii) below):

     (i) the amount of such distribution allocable to principal and the amount allocable to premium, if any;

     (ii) the amount of such distribution allocable to interest; and

     (iii) the Pool Balance and the Pool Factor of the related Trust.

     (b) Within a reasonable period of time after the end of each calendar year but not later than the latest date permitted by law, the Trustee shall furnish to each Person who at any time during such calendar year was a Certificateholder of record a statement containing the sum of the amounts determined pursuant to clauses (a)(i) and (a)(ii) with respect to the related Trust for such calendar year or, in the event such Person was a Certificateholder of record during a portion of such calendar year, for the applicable portion of such year, and such other items as are readily available to the Trustee and which a Certificateholder shall reasonably request as necessary for the purpose of such Certificateholder’s preparation of its Federal Income tax returns.

     Section 4.04. Investment of Special Payment Moneys. Any money received by the Trustee pursuant to Section 4.01(b) representing a Special Payment which is not to be promptly distributed shall, to the extent practicable, be invested in Permitted Government Investments by the Trustee pending distribution of such Special Payment pursuant to Section 4.02. Any investment made pursuant to this Section 4.04 shall be in such Permitted Government Investments having maturities not later than the date that such moneys are required to be used to make the payment required under Section 4.02 on the applicable Special Distribution Date and the Trustee shall hold any such Permitted Government Investments until maturity. The Trustee shall have no liability with respect to any investment made pursuant to this Section 4.04, other than by reason of the willful misconduct or negligence of the Trustee. All income and earnings from such investments shall be distributed on such Special Distribution Date as part of such Special Payment.

ARTICLE V

     Section 5.01. Maintenance of Corporate Existence. The Company, at its own costs and expense, will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, rights and franchises, except as otherwise specifically permitted in Section 5.02; provided, however, that the Company shall not be required to preserve any right or franchise if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not prejudicial in any material respect to the Certificateholders.

     Section 5.02. Consolidation, Merger or Sale of Assets Permitted. (a) The Company covenants that it will not consolidate with or merge into any other corporation or sell, convey or otherwise dispose of all or substantially all of its assets as an entirety to any Person unless the successor or transferee corporation (if other than the Company) shall be a corporation organized and existing under the laws of the United States of America or a state thereof or the District of Columbia, and such corporation shall expressly assume the due and punctual performance and observance of all of the covenants and conditions of this Basic Agreement and the related Trust Supplement to be performed by the Company by supplemental agreement given by such successor corporation to the Trustee.

     (b) The Company agrees with the Certificateholders of each series that, immediately prior to and after giving effect to any transaction described in Section 5.02(a), no Event of Default with respect to Equipment Notes held in the related Trust arising solely as a result of an event of default under a related Lease and no Indenture Event of Default with respect to such Equipment Notes arising solely as a result of an event of default under a related lease, and no event that, after notice or lapse of time, or both, would become such an Event of Default or such an Indenture Event of Default, shall have occurred and be continuing. The Trustee, subject to the provisions of Sections 7.01 and 7.02, may receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale or conveyance, and any such assumption complies with the provisions of this Section 5.02.

     (c) In case of any such merger, consolidation, sale, conveyance or other disposition and upon any such assumption by the successor corporation, such successor corporation shall succeed to and be substituted for the Company hereunder, with the same effect as if it had been named herein as the party of the first part.

ARTICLE VI

     Section 6.01. Events of Default. If in respect of any Trust, any Indenture Event of Default under any applicable Indenture (an “Event of Default”) shall occur and be continuing, then, and in each and every case, so long as such Indenture Event of Default shall be continuing, the Trustee may vote all of the Equipment Notes issued under the applicable Indenture and held in the Trust, and upon the direction of the Certificateholders evidencing Fractional Undivided Interests aggregating not less than a majority in interest in such Trust, the Trustee shall vote a corresponding majority of such Equipment Notes, in favor of directing the Indenture Trustee

under such Indenture, to declare the unpaid principal amount of the Equipment Notes then outstanding to which such Event of Default relates and accrued interest thereon to be due and payable under, and in accordance with the provisions of, the applicable Indenture. In addition, if an Indenture Event of Default shall have occurred and be continuing under any Indenture, the Trustee may in accordance with the applicable Indenture vote the Equipment Notes held in the Trust to which such Event of Default relates to direct the Indenture Trustee regarding the exercise of remedies provided in such Indenture.

     In addition, after an Event of Default shall have occurred and be continuing with respect to any Equipment Notes, the Trustee may in its discretion, and upon the direction of the Certificateholders evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the related Trust shall, by such officer or agent as it may appoint, sell, convey, transfer and deliver such Equipment Note or Equipment Notes, without recourse to or warranty by the Trustee or any Certificateholder, to any Person. In any such case, the Trustee shall sell, assign, contract to sell or otherwise dispose of and deliver such Equipment Note or Equipment Notes in one or more parcels at public or private sale or sales, at any location or locations at the option of the Trustee, all upon such terms and conditions as it may reasonably deem advisable and at such prices as it may reasonably deem advisable, for cash. If the Trustee so decides or is required to sell or otherwise dispose of any Equipment Note pursuant to this Section, the Trustee shall take such of the actions described above as it may reasonably deem most effectual to complete the sale or other disposition of such Equipment Note, so as to provide for the payment in full of all amounts due on the related series of Certificates. The Trustee shall give notice to the Company promptly after any such sale. Notwithstanding the foregoing, any action taken by the Trustee under this Section shall not, in the reasonable judgment of the Trustee, be adverse to the best interests of the Certificateholders of such series.

     Section 6.02. Incidents of Sale of Equipment Notes. Upon any sale of all or any part of the Equipment Notes made either under the power of sale given under this Basic Agreement or the related Trust Supplement or otherwise for the enforcement of this Basic Agreement or the related Trust Supplement, the following shall be applicable:

     (a) Certificateholders and Trustee May Purchase Equipment Notes. Any Certificateholder, the Trustee in its individual or any other capacity or any other Person may bid for and purchase any of the Equipment Notes, and upon compliance with the terms of sale, may hold, retain, possess and dispose of such Equipment Notes in their or its or his own absolute right without further accountability.

     (b) Receipt of Trustee Shall Discharge Purchaser. The receipt of the Trustee or of the officer making such sale shall be a sufficient discharge to any purchaser for his purchase money, and, after paying such purchase money and receiving such receipt, such purchaser or his personal representative or assigns shall not be obliged to see to the application of such purchase money, or be in any way answerable for any loss, misapplication or non-application thereof.

     (c) Application of Moneys Received upon Sale. Any moneys collected by the Trustee upon any sale made either under the power of sale given by this Basic Agreement and the related Trust Supplement or otherwise for the enforcement of this Basic Agreement and the related Trust Supplement, shall be applied as provided in Section 4.02.

     Section 6.03. Judicial Proceedings Instituted by Trustee.

     (a) Trustee May Bring Suit. If there shall be a failure to make payment of the principal of, premium, if any, or interest on any Equipment Note, or if there shall be any failure to pay Rent (as defined in the applicable Lease) under any Lease when due and payable, then the Trustee, in its own name, and as trustee of an express trust, as holder of such Equipment Notes, shall be, to the extent permitted by and in accordance with the terms of the Note Documents, entitled and empowered to institute any suits, actions or proceedings at law, in equity or otherwise, for the collection of the sums so due and unpaid or proceedings at law, in equity or otherwise, for the collection of the sums so due and unpaid on such Equipment Notes or under such Lease and may prosecute any such claim or proceeding to judgment or final decree with respect to the whole amount of any such sums so due and unpaid.

     (b) Trustee May File Proofs of Claim; Appointment of Trustee as Attorney-in-Fact in Judicial Proceedings. The Trustee in its own name, or as trustee of an express trust, or as attorney-in-fact for the Certificateholders of any series, or in any one or more of such capacities (irrespective of whether distributions on the Certificates of any series shall then be due and payable, or the payment of the principal on any Equipment Notes shall then be due and payable, as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand to the relevant Indenture Trustee for the payment of overdue principal, premium (if any) or interest on the Equipment Notes), shall be entitled and empowered to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the Certificateholders of any series allowed in any receivership, insolvency, bankruptcy, liquidation, readjustment, reorganization or any other judicial proceedings relative to the Company or any Owner Trustee or Owner Participant, their respective creditors or property. Any receiver, assignee, trustee, liquidator, sequestrator (or similar official) in any such judicial proceeding is hereby authorized by each Certificateholder to make payments in respect of such claim to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Certificateholders of any series, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. Nothing contained in this Basic Agreement or any related Trust Supplement shall be deemed to give to the Trustee any right to accept or consent to any plan of reorganization or otherwise by action of any character in any such proceeding or to waive or change in any way any right of any Certificateholder of any series.

     Section 6.04. Control by Certificateholders. Subject to Section 2.04, the Certificateholders holding Certificates of a series evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the related Trust shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee under this Basic Agreement or the related Trust Supplement, including any right of the Trustee as holder of the Equipment Notes, provided that:

     (1) such direction shall not be in conflict with any rule of law or with this Basic Agreement or the related Trust Supplement and would not involve the Trustee in personal liability or expense,

     (2) the Trustee shall not determine that the action so directed would be unjustly prejudicial to the Certificateholders of such series not taking part in such direction,

     (3) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

     (4) if any Indenture Event of Default under a related Indenture shall have occurred and be continuing, such direction shall not obligate the Trustee to vote more than a corresponding majority of the related Equipment Notes held by the Trust in favor of directing any action by the Indenture Trustee with respect to such Indenture Event of Default.

     Section 6.05. Waiver of Defaults. The Certificateholders holding Certificates of a series evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the Trust may on behalf of all of the Certificateholders of such series waive any Default or Event of Default and its consequences hereunder or under the related Trust Supplement with respect to such series or may instruct the Trustee to waive any default under the related Indenture, this Basic Agreement or the related Trust Supplement with respect to such series and its consequences, except a Default:

     (1) in the deposit of any Scheduled Payment or Special Payment under Section 4.01 or in the distribution of any payment under Section 4.02 on the Certificates of such series, or

     (2) in the payment of the principal of, premium, if any, or interest on any Equipment Notes, or

     (3) in respect of a covenant or provision hereof which under Article IX hereof cannot be modified or amended without the consent of the Certificateholder of each Outstanding Certificate of such series affected.

     Upon any such waiver, such Default shall cease to exist with respect to the Certificates of such series, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose in respect of such series and any direction given by the Trustee on behalf of the Certificateholders of such series to the Indenture Trustee shall be annulled with respect thereto; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Upon any such waiver, the Trustee shall vote the Equipment Notes issued under the Indenture to waive the corresponding Indenture Default or Indenture Event of Default.

     Section 6.06. Undertaking to Pay Court Costs. All parties to this Basic Agreement and the related Trust Supplement, and each Certificateholder by his acceptance of a Certificate, shall be deemed to have agreed that any court may in its discretion require, in any suit, action or proceeding for the enforcement of any right or remedy under this Basic Agreement or the related Trust Supplement, or in any suit, action or proceeding against the Trustee for any action taken or omitted by it as Trustee hereunder or under the related Trust Supplement, the filing by any party litigant in such suit, action or proceeding of an undertaking to pay the costs of such suit, action or

proceeding, and that such court may, in its discretion, assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, action or proceeding, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, however, that the provisions of this Section shall not apply to (a) any suit, action or proceeding instituted by any Certificateholder or group of Certificateholders of any series evidencing Fractional Undivided Interests aggregating more than 10% of the relevant Trust, (b) any suit, action or proceeding instituted by any Certificateholder of any series for the enforcement of the distribution of payments pursuant to Section 4.02 hereof on or after the respective due dates expressed herein or (c) any suit, action or proceeding instituted by the Trustee.

     Section 6.07. Right of Certificateholders to Receive Payments Not to Be Impaired. Anything in this Basic Agreement or any Trust Supplement to the contrary notwithstanding, including without limitation Section 6.08 hereof, the right of any Certificateholder to receive distributions of payments required pursuant to Section 4.02 hereof on the Certificates when due, or to institute suit for the enforcement of any such payment on or after the applicable Regular Distribution Date or Special Distribution Date, shall not be impaired or affected without the consent of such Certificateholder.

     Section 6.08. Certificateholders May Not Bring Suit Except Under Certain Conditions. A Certificateholder of any series shall not have the right to institute any suit, action or proceeding at law or in equity or otherwise with respect to this Basic Agreement or the related Trust Supplement, for the appointment of a receiver or for the enforcement of any other remedy under this Basic Agreement or the related Trust Supplement, unless:

     (1) such Certificateholder previously shall have given written notice to the Trustee of a continuing Event of Default;

     (2) the Certificateholders holding Certificates of such series evidencing Fractional Undivided Interests aggregating not less than a majority in interest of the Trust shall have requested the Trustee in writing to institute such action, suit or proceeding and shall have offered to the Trustee indemnity as provided in Section 7.03(e);

     (3) the Trustee shall have refused or neglected to institute any such action, suit or proceeding for 60 days after receipt of such notice, request and offer of indemnity; and

     (4) no direction inconsistent with such written request has been given to the Trustee during such 60 day period by the Certificateholders holding Certificates of such series evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the related Trust.

     It is understood and intended that no one or more of the Certificateholders of any series shall have any right in any manner whatever hereunder or under the related Trust Supplement or under the Certificates of such series to (i) surrender, impair, waive, affect, disturb or prejudice any property in the Trust Property of the related Trust or the lien of any applicable Indenture on any property subject thereto, or the rights of the Certificateholders of such series or the holders

of the applicable Equipment Notes, (ii) obtain or seek to obtain priority over or preference to any other Certificateholder of such series or (iii) enforce any right under this Basic Agreement or the related Trust Supplement, except in the manner herein or therein provided and for the equal, ratable and common benefit of all the Certificateholders of such series subject to the provisions of this Basic Agreement and the related Trust Supplement.

     Section 6.09. Remedies Cumulative. Every remedy given hereunder to the Trustee or to any of the Certificateholders of any series shall not be exclusive of any other remedy or remedies, and every such remedy shall be cumulative and in addition to every other remedy given hereunder or now or hereafter given by statute, law, equity or otherwise.

     (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;

then, in any case, (i) the Company may remove the Trustee or (ii) subject to Section 6.06, any Certificateholder of the related series who has been a bona fide Certificateholder for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee of such Trust.

     (e) If a Responsible Officer of the Trustee shall obtain actual knowledge of an Avoidable Tax (as hereinafter defined) in respect of any Trust which has been or is likely to be asserted, the Trustee shall promptly notify the Company and the related Owner Trustees thereof and shall, within 30 days of such notification, resign hereunder unless within such 30 day period the Trustee of such Trust shall have received notice that the Company or the related Owner Trustee has agreed to pay such tax. The Company shall promptly appoint a successor Trustee of such Trust in a jurisdiction where there are no Avoidable Taxes. As used herein an Avoidable Tax means a state or local tax: (i) upon (w) the Trust, (x) the Trust Property of such Trust, (y) Certificateholders of such Trust or (z) the Trustee for which the Trustee is entitled to seek reimbursement from the Trust Property of such Trust, and (ii) which would be avoided if the Trustee were located in another state, or jurisdiction within a state, within the United States. A tax shall not be an Avoidable Tax if the Company or the related Owner Trustee shall agree to pay, and shall pay, such tax.

     (f) If the Trustee shall resign, be removed or become incapable of acting as Trustee of any Trust, or if a vacancy shall occur in the office of the Trustee of any Trust for any cause, the Company shall promptly appoint a successor Trustee of such Trust. If, within 90 days after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee of such Trust shall be appointed by Act of the Certificateholders holding Certificates evidencing Fractional Undivided Interests aggregating not less than a majority in interest in such Trust delivered to the Company, the related Owner Trustee, the related Indenture Trustee and the retiring Trustee, the successor Trustee so appointed of such Trust shall, forthwith upon its acceptance of such appointment, become the successor Trustee of such Trust and supersede the successor Trustee appointed as provided above. If no successor Trustee of such Trust shall have been so appointed as provided above and accepted appointment in the manner hereinafter provided, any Certificateholder who has been a bona fide Certificateholder of the related series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee for such Trust.

     (g) The successor Trustee of a Trust shall give notice of the resignation and removal of the Trustee and appointment of the successor Trustee by mailing written notice of such event by first-class mail, postage prepaid, to the Certificateholders of the related series as their names and addresses appear in the Register. Each notice shall include the name of such successor Trustee and the address of its Corporate Trust Office.

     Section 7.10. Acceptance of Appointment by Successor. (a) Every successor Trustee appointment hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee with respect to the related Trusts shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to related Trusts; but, on request of the Company or the successor Trustee, such retiring Trustee shall execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and such successor Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee with respect to the related Trusts, subject nevertheless to its lien, if any, provided for in Section 7.07. Upon request of any such successor Trustee, the Company, the retiring Trustee and such provisions as shall execute and deliver any and all instruments containing such provisions as shall be necessary or desirable to transfer and confirm to, and for more fully and certainly vesting in, such successor Trustee all such rights, powers and trusts.

     (b) If a successor Trustee is appointed with respect to one or more (but not all) Trusts, the Company, the predecessor Trustee and each successor Trustee with respect to any Trust shall execute and deliver an agreement supplemental hereto which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the predecessor Trustee with respect to the Trusts as to which the predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee, and shall add to or change any of the provisions of this Basic Agreement as shall be necessary to provide for or facilitate the administration of the Trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental agreement shall constitute such Trustee co-Trustees of the same Trust and that each such Trustee shall be Trustee of separate Trusts.

     Section 7.11. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the 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 Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, including the administration of the Basic Agreement, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Certificates shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Certificates so authenticated with the same effect as if such successor Trustee had itself authenticated such Certificates.

     Section 7.12. Maintenance of Agencies. (a) With respect to each series of Certificates, there shall at all times be maintained in the Borough of Manhattan, The City of New York, an office or agency where Certificates of such series may be presented or surrendered for registration of transfer or for exchange, and for payment thereof and where notices and demands to or upon the Trustee in respect of the Certificates or of this Basic Agreement or any Trust Supplement may be served.

Written notice of the location of each such other office or agency and of any change of location thereof shall be given by the Trustee to the Company, the Owner Trustees, the Indenture Trustees and the Certificateholders of such series. In the event that no such office or agency shall be maintained or no such notice of location or of change of location shall be given, presentations and demands may be made and notices may be served at the Corporate Trust Office of the Trustee.

     (b) There shall at all times be a Registrar and a Paying Agent with respect to the Certificates of each series. Each such Authorized Agent shall be a bank or trust company, shall be a corporation organized and doing business under the laws of the United States or any state, with (or, in the case of a subsidiary of a bank holding company, its parent shall have) a combined capital and surplus of at least $100,000,000, and shall be authorized under such laws to exercise corporate trust powers, subject to supervision by Federal or state authorities. The Trustee shall initially be the Paying Agent and, as provided in Section 3.04, Registrar hereunder with respect to the Certificates of each series. Each Registrar shall furnish to the Trustee, at stated intervals of nor more than six months, and at such other times as the Trustee may request in writing, a copy of the Register.

     (d) Any Authorized Agent may at any time resign by giving written notice of resignation to the Trustee, the Company, the related Owner Trustees and the related Indenture Trustees. The Company may, and at the request of the Trustee shall, at any time terminate the agency of any Authorized Agent by giving written notice of termination to such Authorized Agent and to the Trustee. Upon the resignation or termination of an Authorized Agent or in case at any time any such Authorized Agent shall cease to be eligible under this Section (when, in either case, no other Authorized Agent performing the functions of such Authorized Agent shall have been appointed), the Company shall promptly appoint one or more qualified successor Authorized Agents, reasonably satisfactory to the Trustee, to perform the functions of the Authorized Agent which has resigned or whose agency has been terminated or who shall have ceased to be eligible under this Section. The Company shall give written notice of any such appointment made by it to the Trustee, the related Owner Trustees and the related Indenture Trustees; and in each case the Trustee shall mail notice of such appointment to all Certificateholders of the related series as their names and addresses appear on the Register for such series.

     (e) The Company agrees to pay, or cause to be paid, from time to time to each Authorized Agent the compensation as set forth in the schedule agreed to by each Authorized Agent and the Company for its services and to reimburse it for its reasonable expenses.

     Section 7.13. Money for Certificate Payments to Be Held in Trust. All moneys deposited with any Paying Agent for the purpose of any payment on Certificates of any series shall be deposited and held in trust for the benefit of the Certificateholders entitled to such payment, subject to the provisions of this Section. Moneys so deposited and held in trust shall constitute a separate trust fund for the benefit of the Certificateholders with respect to which such money was deposited.

     The Trustee will cause each Paying Agent other than the Trustee to execute and deliver to it an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will

[REVERSE OF CERTIFICATE]

     The Certificates do not represent a direct obligation of, or an obligation guaranteed by, or an interest in, the Company or the Trustee or any affiliate thereof. The Certificates are limited in right of payment, all as more specifically set forth on the face hereof and in the Agreement. All payments or distributions made to Certificateholders under the Agreement 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 the Agreement. Each Holder of this Certificate, by its acceptance hereof, agrees that it will look solely to the income and proceeds from the Trust Property to the extent available for distribution to such holder as provided in the Agreement. This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for information with respect to the interests, rights, benefits, obligations, proceeds, and duties evidenced hereby. A copy of the Agreement may be examined during normal business hours at the principal office of the Trustee, and at such other places, if any, designated by the Trustee, by any Certificateholder upon request.

     The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Certificateholders under the Agreement at any time by the Company and the Trustee with the consent of the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the Trust. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

     As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Register upon surrender of this Certificate for registration of transfer at the offices or agencies maintained by the Trustee in its capacity as Registrar, or by any successor Registrar, in the Borough of Manhattan, the City of New York, duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Registrar duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the Trust will be issued to the designated transferee or transferees.

     The Certificates are issuable only as registered Certificates without coupons in denominations of $1,000 Fractional Undivided Interest and any integral multiples of $1,000 in excess thereof except that one Certificate may be in a denomination of less than $1,000. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of authorized denominations and like series evidencing the same aggregate Fractional Undivided Interest in the Trust, as requested by the Holder surrendering the same.

     No service charge will be made for any such registration of transfer or exchange, but the Trustee shall require payment of a sum sufficient to cover any tax or governmental charge payable in connection therewith.

     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.
