It is the intention of the parties hereto that, solely for purposes of federal income taxes, state and local income and franchise taxes, and any other taxes imposed upon, measured by, or based upon gross or net income, the Trust shall be treated as a division or branch of the Seller. The parties agree that, unless otherwise required by appropriate tax authorities, the Trust shall file or cause to be filed annual or other necessary returns, reports and other forms consistent with the characterization of the Trust as a division or branch of the Seller for such tax purposes; provided, however, that until the Seller receives a ruling from the Illinois Department of Revenue or an opinion of counsel reasonably acceptable to the Owner Trustee that the Trust will be treated as a branch or division of the Seller for purposes of the Illinois Income Tax Act and the Illinois Personal Property Tax Replacement Tax Act, for purposes of the Illinois Income Tax Act and the Illinois Personal Property Tax Replacement Tax Act, the Seller will (i) include the taxable income of the Trust in the combined tax return filed by the combined group that includes the Seller, (ii) take all steps necessary to treat the Trust as a member of the same combined group of which the Seller is a member and (iii) provide information to the Owner Trustee to confirm that the actions required by clauses (i) and (ii) have been effected.

SECTION 2.7 Liability of the Certificateholders. No Certificateholder shall have any personal liability for any liability or obligation of the Trust.

SECTION 2.8 Title to Trust Property. Legal title to all the Owner Trust Estate shall be vested at all times in the Trust as a separate legal entity, except where applicable law in any jurisdiction requires title to any part of the Owner Trust Estate to be vested in a trustee or trustees, in which case title shall be deemed to be vested in the Owner Trustee, a co-trustee and/or other trustees, as the case may be.

SECTION 2.9 Situs of Trust. The Trust shall be located and administered in the State of Delaware. All bank accounts maintained by the Trust or the Owner Trustee on behalf of the Trust or for the benefit of the Certificateholders shall be located in the State of Delaware or the State of New York.

ARTICLE III

THE CERTIFICATES

SECTION 3.1 Initial Certificate Ownership. Upon the formation of the Trust by the contribution by the Seller pursuant to Section 2.5 and until the issuance of the Certificates, the Seller shall be the sole beneficiary of the Trust.

SECTION 3.2 Form of the Certificates.

(a) The Certificates shall be substantially in the form set forth in Exhibit A. The Certificates shall be executed on behalf of the Trust by manual or facsimile signature of a Responsible Officer of the Owner Trustee. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures shall have been affixed, authorized to sign on behalf of the Trust, shall be, when authenticated pursuant to Section 3.3, validly issued and entitled to the benefits of this Agreement, notwithstanding that such individuals or any of them shall have ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such offices at the date of authentication and delivery of such Certificates.

(b) The Certificates shall be typewritten, printed, lithographed or engraved or produced by any combination of these methods (with or without steel engraved borders) all as determined by the officers executing such Certificates, as evidenced by their execution of such Certificates.

(c) The Certificates shall be issued in fully-registered form and shall be in definitive form only. The terms of the Certificates set forth in Exhibit A shall form part of this Agreement.

SECTION 3.3 Execution, Authentication and Delivery. Concurrently with the sale of the Initial Receivables to the Trust pursuant to the Pooling Agreement, the Owner Trustee shall cause the Certificates to be executed on behalf of the Trust, and to be authenticated and delivered to or upon the written order of the Seller, signed by its chairman of the board, its president or any vice president, without further corporate action by the Seller, in authorized denominations. No Certificate shall entitle its holder to any benefit under this Agreement, or shall be valid for any purpose, unless there shall appear on such Certificate a certificate of authentication substantially in the form set forth in Exhibit A, executed by the Owner Trustee or by the Person appointed from time to time as the Owner Trustee’s authenticating agent hereunder (the “Authenticating Agent”) by manual signature. The Owner Trustee hereby appoints The Bank of New York Mellon as the initial Authenticating Agent. Such authentication shall constitute conclusive evidence that such Certificate shall have been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication.

SECTION 3.4 Registration; Registration of Transfer and Exchange of Certificates.

(a) The Certificate Registrar shall keep or cause to be kept, at the office or agency maintained pursuant to Section 3.8, a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Owner Trustee shall provide for the registration of

- 5 -

Certificates and of transfers and exchanges of Certificates as provided herein. The Certificate Registrar shall be appointed by and may be removed by the Owner Trustee. The Bank of New York Mellon is hereby appointed as the initial Certificate Registrar. Upon any resignation of a Certificate Registrar, the Owner Trustee shall promptly appoint a successor or, if it elects not to make such an appointment, assume the duties of Certificate Registrar.

(b) A Certificateholder may at any time, without consent of the Noteholders, sell, transfer, convey or assign in any manner its rights to and interests in the Certificates (including its right to distributions from the Reserve Account pursuant to Section 8.10(b) of the Indenture), provided that: (i) the Certificateholder provides to the Owner Trustee and the Indenture Trustee an opinion of independent counsel that such action will not cause the Trust to be treated as an association (or publicly traded partnership) taxable as a corporation for federal income tax purposes, (ii) such transferee or assignee agrees to take positions for tax purposes consistent with the tax positions agreed to be taken by the Certificateholder and (iii) the conditions set forth in Section 3.4(g) have been satisfied. For the avoidance of doubt, any transfer of a Certificate by a Certificateholder other than the initial Certificateholder also must comply with the foregoing proviso. In addition, no transfer of a Certificate shall be registered unless the transferee shall have provided to the Owner Trustee and the Certificate Registrar an opinion of counsel that in connection with such transfer no registration of the Certificates is required under the Securities Act or applicable state law or that such transfer is otherwise being made in accordance with all applicable federal and state securities laws.

(c) Subject to Section 3.4(b), upon surrender for registration of transfer of any Certificate at the office or agency maintained pursuant to Section 3.8, the Owner Trustee shall execute on behalf of the Trust, authenticate and deliver (or shall cause its Authenticating Agent to authenticate and deliver), in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations of a like aggregate amount dated the date of authentication by the Owner Trustee or any authenticating agent.

(d) At the option of a Holder, Certificates may be exchanged for other Certificates of a like aggregate percentage interest upon surrender of the Certificates to be exchanged at the Corporate Trust Office or the office or agency maintained pursuant to Section 3.8. Whenever any Certificates are so surrendered for exchange, the Owner Trustee shall execute on behalf of the Trust, authenticate and deliver (or shall cause its Authenticating Agent to authenticate and deliver) one or more Certificates dated the date of authentication by the Owner Trustee or any Authenticating Agent. Such Certificates shall be delivered to the Holder making the exchange.

(e) Every Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Owner Trustee and the Certificate Registrar duly executed by the Holder or his attorney duly authorized in writing. Each Certificate surrendered for registration of transfer or exchange shall be canceled and subsequently destroyed or otherwise disposed of by the Owner Trustee or Certificate Registrar in accordance with its customary practice.

(f) No service charge shall be made for any registration of transfer or exchange of Certificates, but the Owner Trustee or the Certificate Registrar may require payment

- 6 -

of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

(g) The Certificates may not be acquired by or for the account of a Benefit Plan. By accepting and holding a Certificate, the Holder thereof shall be deemed to have represented and warranted that it is not a Benefit Plan.

SECTION 3.5 Mutilated, Destroyed, Lost or Stolen Certificates.

(a) If (i) any mutilated Certificate is surrendered to the Certificate Registrar, or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate, and (ii) there is delivered to the Certificate Registrar, the Owner Trustee and the Trust, such security or indemnity as may be required by them to hold each of them harmless, then, in the absence of notice to the Certificate Registrar, the Owner Trustee or the Trust that such Certificate has been acquired by a protected purchaser, the Owner Trustee shall execute on behalf of the Trust and the Owner Trustee shall authenticate and deliver (or shall cause its Authenticating Agent to authenticate and deliver), in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a replacement Certificate in authorized denominations of a like amount; provided, however, that if any such destroyed, lost or stolen Certificate, but not a mutilated Certificate, shall have become or within seven days shall be due and payable, then instead of issuing a replacement Certificate the Owner Trustee on behalf of the Trust may pay such destroyed, lost or stolen Certificate when so due or payable.

(b) If, after the delivery of a replacement Certificate or distribution in respect of a destroyed, lost or stolen Certificate pursuant to Section 3.5(a), a protected purchaser of the original Certificate in lieu of which such replacement Certificate was issued presents for payment such original Certificate, the Owner Trustee on behalf of the Trust shall be entitled to recover such replacement Certificate (or such distribution) from the Person to whom it was delivered or any Person taking such replacement Certificate from such Person to whom such replacement Certificate was delivered or any assignee of such Person, except a protected purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Trust or the Owner Trustee in connection therewith.

(c) In connection with the issuance of any replacement Certificate under this Section 3.5, the Owner Trustee on behalf of the Trust may require the payment by the Holder of such Certificate of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the fees and expenses of the Trust, the Owner Trustee and the Certificate Registrar) connected therewith.

(d) Any duplicate Certificate issued pursuant to this Section 3.5 in replacement of any mutilated, destroyed, lost or stolen Certificate shall constitute an original additional contractual obligation of the Trust, whether or not the mutilated, destroyed, lost or stolen Certificate shall be found at any time or be enforced by anyone, and shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Certificates duly issued hereunder.

- 7 -

(e) The provisions of this Section 3.5 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 3.6 Persons Deemed Certificateholders. Prior to due presentation of a Certificate for registration of transfer, the Owner Trustee or the Certificate Registrar may treat the Person in whose name any Certificate shall be registered in the Certificate Register as the Certificateholder of such Certificate for the purpose of receiving distributions pursuant to Article V and for all other purposes whatsoever, and neither the Owner Trustee nor the Certificate Registrar shall be bound by any notice to the contrary.

SECTION 3.7 Access to List of Certificateholders’ Names and Addresses. The Owner Trustee shall furnish or cause to be furnished to the Servicer and the Seller, within 15 days after receipt by the Owner Trustee of a request therefor from the Servicer or the Seller in writing, a list, in such form as the Servicer or the Seller may reasonably require, of the names and addresses of the Certificateholders as of the most recent Record Date. Each Holder, by receiving and holding a Certificate, shall be deemed to have agreed not to hold any of the Servicer, the Seller, the Trust or the Owner Trustee accountable by reason of the disclosure of its name and address, regardless of the source from which such information was derived.

SECTION 3.8 Maintenance of Corporate Trust Office. The Trust shall maintain in the Borough of Manhattan, the City of New York, an office or offices or agency or agencies where Certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Trust in respect of the Certificates and the Basic Documents may be served. The Trust initially designates the offices of the Certificate Registrar at 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, as its principal office for such purposes. The Owner Trustee shall give prompt written notice to the Seller and to the Certificateholders of any change in the location of the Certificate Register or any such office or agency.

SECTION 3.9 Appointment of Paying Agent. The Paying Agent shall make distributions to Certificateholders from the Certificate Distribution Account pursuant to Section 5.2. Any Paying Agent shall have the revocable power to withdraw funds from the Certificate Distribution Account for the purpose of making the distributions referred to above. The Owner Trustee may appoint and may revoke such power and remove the Paying Agent if the Owner Trustee determines in its sole discretion that the Paying Agent shall have failed to perform its obligations under this Agreement in any material respect. The Bank of New York Mellon is hereby appointed as the initial Paying Agent. The Paying Agent shall be permitted to resign as Paying Agent upon 30 days’ written notice to the Owner Trustee. If the Paying Agent shall resign or be removed, the Owner Trustee shall appoint a successor to act as Paying Agent (which shall be a bank or trust company). The Owner Trustee shall cause such successor Paying Agent or any additional Paying Agent appointed by the Owner Trustee to execute and deliver to the Owner Trustee an instrument in which such successor Paying Agent or additional Paying Agent shall agree with the Owner Trustee that as Paying Agent, such successor Paying Agent or additional Paying Agent shall hold all sums, if any, held by it for distribution to the Certificateholders in trust for the benefit of the Certificateholders entitled thereto until such sums shall be paid to such Certificateholders. The Paying Agent shall return all unclaimed funds to the Trust and upon removal of a Paying Agent such Paying Agent shall also return all funds in

- 8 -

its possession to the Trust. The provisions of Sections 6.3, 6.6, 6.7, 6.8 and 6.9 shall apply, mutatis mutandis, to the Owner Trustee also in its role as Paying Agent, for so long as the Owner Trustee shall act as Paying Agent and, to the extent applicable, to any other paying agent appointed hereunder. Any reference in this Agreement to the Paying Agent shall include any co-paying agent unless the context requires otherwise.

SECTION 3.10 Seller as Certificateholder. The Seller in its individual or any other capacity may become the owner or pledgee of Certificates and may otherwise deal with the Owner Trustee or its Affiliates as if it were not the Seller.

SECTION 4.4 Restrictions on Certificateholders’ Power. The Certificateholders shall not direct the Owner Trustee to take or refrain from taking any action if such action or inaction would be contrary to any obligation of the Trust or the Owner Trustee under this Agreement or any of the Basic Documents or would be contrary to Section 2.3, nor shall the Owner Trustee be obligated to follow any such direction, if given.

SECTION 4.5 Majority Control. Except as expressly provided herein, any action that may be taken or consent that may be given or withheld by the Certificateholders under this Agreement shall be effective if such action is taken or such consent is given or withheld by the Holders of a majority of the ownership interest in the Trust outstanding as of the close of the preceding Distribution Date. Except as expressly provided herein, any written notice, instruction, direction or other document of the Certificateholders delivered pursuant to this Agreement shall be effective if signed by Holders of Certificates evidencing not less than a majority of the ownership interest in the Trust at the time of the delivery of such notice.

ARTICLE V

APPLICATION OF TRUST FUNDS; CERTAIN DUTIES

SECTION 5.1 Establishment of Certificate Distribution Account.

(a) The Seller shall cause the Servicer, for the benefit of the Certificateholders, to establish and maintain at The Bank of New York Mellon in the name of the Trust an Eligible Deposit Account known as the Navistar Financial 2008-B Owner Trust Certificate Distribution Account (the “Certificate Distribution Account”), bearing an additional designation clearly indicating that the funds deposited therein are held for the benefit of the Certificateholders.

- 10 -

(b) The Trust, for the benefit of the Certificateholders, shall possess all right, title and interest in and to all funds on deposit from time to time in the Certificate Distribution Account and in all proceeds thereof. Except as otherwise provided herein or in the Pooling Agreement or the Servicing Agreement, the Certificate Distribution Account shall be under the sole dominion and control of the Paying Agent for the benefit of the Certificateholders. If, at any time, the Certificate Distribution Account ceases to be an Eligible Deposit Account, the Seller shall cause the Servicer within 10 Business Days (or such longer period, not to exceed 30 calendar days, as to which the Certificateholders may consent) to establish a new Certificate Distribution Account as an Eligible Deposit Account and shall cause the Paying Agent to transfer any cash and/or any investments in the old Certificate Distribution Account to such new Certificate Distribution Account.

SECTION 5.2 Application of Trust Funds.

(a) On each Distribution Date, the Paying Agent shall (based on the information contained in the Servicer’s Certificate delivered on the related Determination Date) distribute to the Certificateholders, on a pro rata basis, amounts on deposit in the Certificate Distribution Account.

(b) On each Distribution Date, the Paying Agent shall send (or shall cause to be sent) to each Certificateholder the statement described in Section 2.17(a) of the Servicing Agreement.

(c) If any withholding tax is imposed on distributions of the Owner Trust Estate (or allocations of income) to a Certificateholder, such tax shall reduce the amount otherwise distributable to the Certificateholder in accordance with this Section 5.2. The Paying Agent is hereby authorized and directed to retain from amounts otherwise distributable to the Certificateholders sufficient funds for the payment of any withholding tax that is legally owed by the Trust in respect of any distribution (but such authorization shall not prevent the Owner Trustee from contesting any such tax in appropriate proceedings and withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The amount of any withholding tax imposed with respect to a Certificateholder shall be treated as cash distributed to such Certificateholder at the time it is withheld by the Trust and remitted to the appropriate taxing authority. If there is a possibility that withholding tax is payable with respect to a distribution (such as a distribution to a non-U.S. Certificateholder), the Paying Agent may in its sole discretion withhold such amounts in accordance with this Section 5.2(c). If a Certificateholder wishes to apply for a refund of any such withholding tax, the Owner Trustee and the Paying Agent shall reasonably cooperate with such Certificateholder in making such claim so long as such Certificateholder agrees to reimburse the Trust, the Owner Trustee and the Paying Agent for any out-of-pocket expenses incurred.

(d) If the Indenture Trustee holds escheated funds for payment to the Trust pursuant to Section 3.3(e) of the Indenture, the Owner Trustee shall, upon notice from the Indenture Trustee that such funds exist, submit on behalf of the Trust an Issuer Order to the Indenture Trustee pursuant to Section 3.3(e) of the Indenture instructing the Indenture Trustee to pay such funds pro rata to or at the order of the Certificateholders.

SECTION 5.3 Method of Payment. Subject to Section 7.1(c), distributions required to be made to Certificateholders on any Distribution Date shall be made to each Certificateholder of record on the related Record Date (i) by wire transfer, in immediately available funds, to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor or, where possible, by intra-bank book entry credit, if such Certificateholder shall have provided to the Certificate Registrar appropriate written instructions at least five Business Days prior to such Record Date and the distribution required to be made to such Certificateholders exceeds $100,000 or (ii) by check mailed to such Certificateholder at the address of such Certificateholder appearing in the Certificate Register.

SECTION 5.4 Accounting and Reports to the Certificateholders, the Internal Revenue Service and Others. The Trust shall maintain (or cause to be maintained) the books of the Trust on the basis of a fiscal year ending October 31 on the accrual method of accounting, deliver to each Certificateholder, as may be required by the Code and applicable Treasury Regulations or otherwise, such information as may be required to enable each Certificateholder to prepare its federal income tax returns, file such tax returns relating to the Trust and make such elections as may from time to time be required or appropriate under any applicable state or federal statute or rule or regulation thereunder so as to maintain the Trust’s characterization as a division or branch of the Seller for federal income tax purposes, cause such tax returns to be signed in the manner required by law and collect or cause to be collected any withholding tax as described in and in accordance with Section 5.2(c) with respect to income or distributions to Certificateholders.

SECTION 5.5 Signature on Returns. The Owner Trustee shall sign on behalf of the Trust any and all tax returns of the Trust as directed by the Seller, unless applicable law requires a Certificateholder to sign such documents, in which case such documents shall be signed by the Seller.

(b) Notwithstanding the foregoing, the Owner Trustee shall not be required to take any action hereunder or under any Basic Document if the Owner Trustee shall have reasonably determined, or shall have been advised by counsel, that such action is likely to result in liability on the part of the Owner Trustee or is contrary to the terms hereof or of any Basic Document or is otherwise contrary to law.

(c) Whenever the Owner Trustee is unable to decide between alternative courses of action permitted or required by the terms of this Agreement or any Basic Document, or is unsure as to the application, intent, interpretation or meaning of any provision of this Agreement or the Basic Documents, the Owner Trustee shall promptly give notice (in such form as shall be appropriate under the circumstances) to the Certificateholders requesting instruction

(d) The execution, delivery and performance by the Owner Trustee of this Agreement shall not require the authorization, consent or approval of, the giving of notice to, the filing or registration with, or the taking of any other action in respect of, any governmental authority or agency regulating the corporate trust activities of the Owner Trustee.

SECTION 6.7 Reliance; Advice of Counsel.

(a) The Owner Trustee shall incur no liability to anyone in acting upon any signature, instrument, notice, resolution, request, consent, order, certificate, report, opinion, bond or other document or paper believed by it to be genuine and believed by it to be signed by the proper party or parties and need not investigate any fact or matter in any such document. The Owner Trustee may accept a certified copy of a resolution of the board of directors or other governing body of any corporate party as conclusive evidence that such resolution has been duly adopted by such body and that the same is in full force and effect. As to any fact or matter the method of the determination of which is not specifically prescribed herein, the Owner Trustee may for all purposes hereof rely on a certificate, signed by the president or any vice president or by the treasurer or other authorized officers of the relevant party, as to such fact or matter, and such certificate shall constitute full protection to the Owner Trustee for any action taken or omitted to be taken by it in good faith in reliance thereon.

(b) In the exercise or administration of the trusts hereunder and in the performance of its duties and obligations under this Agreement or the Basic Documents, the Owner Trustee: may act directly or through its agents, attorneys, custodians or nominees pursuant to agreements entered into with any of them, and the Owner Trustee shall not be liable for the conduct or misconduct of such agents, attorneys, custodians or nominees if such agents, attorneys, custodians or nominees shall have been selected by the Owner Trustee with reasonable care; and may consult with counsel, accountants and other skilled professionals to be selected with reasonable care and employed by it.

SECTION 6.8 Owner Trustee May Own Certificates and Notes. The Owner Trustee in its individual or any other capacity may become the owner or pledgee of Certificates or Notes and may deal with the Seller, the Administrator, the Indenture Trustee and the Servicer in transactions in the same manner as it would have if it were not the Owner Trustee.

SECTION 6.10 Replacement of Owner Trustee.

(a) The Owner Trustee may give notice of its intent to resign and be discharged from the trusts hereby created by written notice thereof to the Administrator; provided that no such resignation shall become effective, and the Owner Trustee shall not resign, prior to the time set forth in Section 6.10(c). The Administrator may appoint a successor Owner Trustee by delivering a written instrument, in duplicate, to the resigning Owner Trustee and the successor Owner Trustee. If no successor Owner Trustee shall have been appointed and have accepted appointment within 30 days after the giving of such notice, the resigning Owner Trustee giving such notice may petition any court of competent jurisdiction for the appointment of a successor Owner Trustee. The Administrator shall remove the Owner Trustee if:

(i) the Owner Trustee shall cease to be eligible in accordance with the provisions of Section 6.13 and shall fail to resign after written request therefor by the Administrator;

(c) Any resignation or removal of the Owner Trustee and appointment of a successor Owner Trustee pursuant to any of the provisions of this Section 6.10 shall not become effective and no such resignation shall be deemed to have occurred until a written acceptance of appointment is delivered by the successor Owner Trustee to the outgoing Owner Trustee and the Administrator and all fees and expenses due to the outgoing Owner Trustee are paid. Any successor Owner Trustee appointed pursuant to this Section 6.10 shall be eligible to act in such capacity in accordance with Section 6.13 and, following compliance with the preceding sentence, shall become fully vested with all the rights, powers, duties and obligations of its predecessor under this Agreement, with like effect as if originally named as Owner Trustee. The Administrator shall provide notice of such resignation or removal of the Owner Trustee to the Agent and the Rating Agencies.

SECTION 6.12 Appointment of Co-Trustee or Separate Trustee.

(a) Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirement of any jurisdiction in which any part of the Owner Trust Estate or any Financed Vehicle may at the time be located, the Administrator and the Owner Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Owner Trustee to act as co-trustee, jointly with the Owner Trustee, or as separate trustee or trustees, of all or any part of the Owner Trust Estate, and to vest in such Person, in such capacity, such title to the Owner Trust Estate, or any part thereof, and, subject to the other provisions of this Section 6.12, such powers, duties, obligations, rights and trusts as the Administrator and the Owner Trustee may consider necessary or desirable. If the Administrator shall not have joined in such appointment within 15 days after the receipt by it of a request to do so, the Owner Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee under this Agreement shall be required to meet the terms of eligibility as a successor trustee pursuant to Section 6.13 and no notice of the appointment of any co-trustee or separate trustee shall be required pursuant to Section 6.10.

- 19 -

to the Owner Trust Estate or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Owner Trustee;

(ii) no trustee under this Agreement shall be personally liable by reason of any act or omission of any other trustee under this Agreement (unless such other trustee acts or fails to act at the direction of such first trustee); and

(iii) the Administrator and the Owner Trustee acting jointly may at any time accept the resignation of or remove any separate trustee or co-trustee.

(c) Any notice, request or other writing given to the Owner Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article VI. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Owner Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Owner Trustee. Each such instrument shall be filed with the Owner Trustee and a copy thereof given to the Administrator.

(d) Any separate trustee or co-trustee may at any time appoint the Owner Trustee as its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Owner Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

If such Person or bank shall publish reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purpose of this Section 6.13, the combined capital and surplus of such Person or bank shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Owner Trustee shall cease to be eligible in accordance with the provisions of this Section 6.13, the Owner Trustee shall resign immediately in the manner and with the effect specified in Section 6.10.

(a) The Trust shall dissolve and wind up in accordance with Section 3808 of the Statutory Trust Statute on or immediately preceding the final distribution by the Owner Trustee of all monies or other property or proceeds of the Owner Trust Estate in accordance with the terms of the Indenture, the Pooling Agreement (including the exercise by the Servicer of its option to purchase the Receivables pursuant to Section 4.01 of the Pooling Agreement), the Servicing Agreement and Article V of this Agreement. The bankruptcy, liquidation, dissolution, death or incapacity of any Certificateholder shall not (x) operate to terminate this Agreement or the Trust, nor (y) entitle such Certificateholder’s legal representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding up of all or any part of the Trust or the Owner Trust Estate, nor (z) otherwise affect the rights, obligations and liabilities of the parties hereto.

(b) This Agreement shall be irrevocable. Except as provided in Section 7.1(a) and in this Section 7.1(b), neither the Seller nor any Certificateholder shall be entitled to revoke or terminate the Trust or this Agreement. Each of the Seller, the Trust and the Owner Trustee acknowledges that the Indenture Trustee, on behalf of the Noteholders, is a third-party beneficiary of this Agreement. For so long as the Notes are outstanding, neither the Trust nor this Agreement shall be revoked without the consent of the Indenture Trustee. Each of the Seller, the Trust and the Owner Trustee acknowledges that the Indenture Trustee, as an agent of the Noteholders, maintains a legitimate interest in ensuring that the Trust is not revoked prior to the fulfillment of the Trust objectives. In no event may this Agreement be amended without the consent of the Indenture Trustee if the effect of such amendment is the revocation or termination of this Trust other than in accordance with this Section 7.1.

(c) Notice of any dissolution of the Trust specifying the Distribution Date upon which the Certificateholders shall surrender their Certificates to the Owner Trustee for payment of the final distribution and cancellation, shall be given by the Owner Trustee by letter to Certificateholders mailed within five Business Days of receipt of notice of dissolution from the Servicer given pursuant to Section 8.13(b) of the Indenture, stating: (i) the Distribution Date upon or with respect to which the final distribution on the Certificates shall be made upon presentation and surrender of the Certificates at the office of the Owner Trustee; (ii) the amount of any such final distribution; and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, distributions being made only upon presentation and surrender of the Certificates at the office of the Owner Trustee therein specified.

Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within one year after the second notice all the Certificates shall not have been surrendered for cancellation, the Owner Trustee may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets that shall remain subject to this Agreement. Subject to applicable laws with respect to escheat of funds, any funds remaining in the Owner Trust Estate after exhaustion of such remedies in the preceding sentence shall be deemed property of the Seller and distributed by the Owner Trustee to the Seller.

(e) Within sixty days of the later of (i) the cancellation of all of the Certificates pursuant to Section 7.1(c) or 7.1(d), or (ii) payment to the Seller of funds remaining in the Owner Trust Estate pursuant to Section 7.1(d), the Owner Trustee shall provide the Agent and the Rating Agencies with written notice stating that all Certificates have been so canceled or such funds have been so paid to the Seller.
