ORGANIZATION OF THE TRUST

Section 2.1 Name. The Trust shall be known as “CarMax Auto Owner Trust 20[ ]-[ ],” in which name the Owner Trustee may conduct the business of the Trust, make and execute contracts and other instruments on behalf of the Trust and ▇▇▇ and be sued on behalf of the Trust.

Section 2.2 Office. The office of the Trust shall be in care of the Owner Trustee at the Corporate Trust Office or at such other address as the Owner Trustee may designate by written notice to the Certificateholders and the Depositor.

Section 2.3 Purposes and Powers. The purpose of the Trust is, and the Trust shall have the power and authority, to engage solely in the following activities:

(i) to issue the Notes pursuant to the Indenture and the Certificates pursuant to this Trust Agreement, and to sell the Notes upon the written order of the Depositor;

(ii) to use the proceeds of the sale of the Notes, at the direction of the Depositor, to fund the Reserve Account, to pay the organizational, start-up and transactional expenses of the Trust and to pay the balance to the Depositor pursuant to the Sale and Servicing Agreement;

(iii) to pay interest on and principal of the Notes and to pay Excess Collections to the Certificateholders;

(iv) to assign, grant, transfer, pledge, mortgage and convey the Owner Trust Estate (other than the Certificate Payment Account and the proceeds thereof) to the Indenture Trustee pursuant to the Indenture;

(v) to enter into and perform its obligations under the Transaction Documents to which it is to be a party;

(vi) subject to compliance with the Transaction Documents, to engage in such other activities as may be required in connection with conservation of the Owner Trust Estate and the making of distributions to the Noteholders and the Certificateholders; [and]

(vii) to engage in those activities, including entering into agreements, that are necessary, suitable or convenient to accomplish the foregoing or are incidental thereto or connected therewith[.][; and]

(viii) [to enter into interest rate swaps or caps in connection with the Notes.]

The Trust is hereby authorized to engage in the foregoing activities. The Trust shall not engage in any activity other than in connection with the foregoing or other than as required or authorized by the terms of this Trust Agreement or the other Transaction Documents.

Section 2.4 Appointment of Owner Trustee. The Depositor hereby appoints the Owner Trustee as trustee of the Trust effective as of the date hereof, to have all the rights, powers and duties set forth herein and in the Statutory Trust Statute.

Section 2.5 Initial Capital Contribution of Owner Trust Estate. The Depositor has sold, assigned, transferred, conveyed and set over to the Owner Trustee the sum of $100. The Owner Trustee hereby acknowledges receipt in trust from the Depositor of such amount, which amount constituted the initial Owner Trust Estate and was deposited in the Certificate Payment Account. The Depositor shall pay organizational expenses of the Trust as they may arise or shall, upon the request of the Owner Trustee, promptly reimburse the Owner Trustee for any such expenses paid by the Owner Trustee.

Section 2.6 Declaration of Trust. The Owner Trustee hereby declares that it will hold the Owner Trust Estate in trust upon and subject to the conditions set forth herein for the use and benefit of the Certificateholders, subject to the obligations of the Trust under the Transaction Documents. It is the intention of the parties hereto that (i) the Trust constitute a statutory trust under the Statutory Trust Statute and that this Trust Agreement constitute the governing instrument of such statutory trust and (ii) solely for income and franchise tax purposes, the Trust shall be treated (A) if it has one beneficial owner, as a non-entity and (B) if it has more than one beneficial owner, as a partnership, with the assets of the partnership being the Receivables and other assets held by the Trust, the partners of the partnership being the Certificateholders and the Notes constituting indebtedness of the partnership. Unless otherwise required by the 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 either as a nonentity or as a partnership for such tax purposes. Effective as of the date hereof, the Owner Trustee shall have all rights, powers and duties set forth herein and in the Statutory Trust Statute with respect to accomplishing the purposes of the Trust. The parties have caused the filing of the Certificate of Trust with the Secretary of State. If it is determined that, contrary to the intent of the parties hereto and the position of the Certificateholder, the Trust has “gross receipts” for purposes of HB3, it is the intention of the parties hereto that the Trust be treated as a “passive entity” for purposes of HB3, formed to hold assets to facilitate securitization

transactions in a manner similar to grantor trusts and real estate mortgage investment conduits as defined by Section 860D of the Code. The Depositor, and the Certificateholders by acceptance of a Certificate, agree that if it is determined that, contrary to the intent of the parties hereto and the position of the Certificateholder, the Trust has “gross receipts” for purposes of HB3, they will, unless otherwise required by law, treat the Trust as a “passive entity” for purposes of HB3 and will not, unless otherwise required by law, take any action to include the Trust as part of an affiliated group engaged in a unitary business (as such terms are used in HB3). Notwithstanding anything to the contrary contained herein, nothing in this Trust Agreement should be read to imply that the Trust is doing business in Texas or has sufficient nexus with Texas in order for HB3 to apply to the Trust.

Section 2.7 Liability of Certificateholders. The Certificateholders shall be entitled to the same limitation of personal liability extended to stockholders of private corporations organized under the general corporation law of the State of Delaware.

Section 2.8 Title to Trust Property. Legal title to the entirety of 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 or a separate trustee, as the case may be; provided, that concurrently with or prior to title being deemed to be vested in a co-trustee or a separate trustee, such trustee must provide a written grant of a security interest in the Owner Trust Estate to the Indenture Trustee and must authorize the filing of a financing statement to perfect the Indenture Trustee’s security interest.

Section 2.9 Situs of Trust. The Trust shall be located and administered in the State of Delaware or the State of [ ]. All bank accounts maintained by the Owner Trustee on behalf of the Trust shall be located in the State of Delaware or the State of [ ]. The Trust shall not have any employees in any State other than the State of Delaware; provided, however, that nothing herein shall restrict or prohibit the Owner Trustee from having employees within or without the State of Delaware. Payments will be received by the Trust only in the State of Delaware or the State of [ ], and payments will be made by the Trust only from the State of Delaware or the State of [ ]. The principal office of the Trust will be at the Corporate Trust Office in the State of [ ].

Section 2.10 Representations and Warranties of the Depositor. The Depositor hereby represents and warrants to the Owner Trustee that:

(i) the Depositor has been duly organized and is validly existing as a limited liability company in good standing under the laws of the State of Delaware, has the power, authority and legal right to own its properties and to conduct its business as such properties are currently owned and such business is currently conducted, and has the power, authority and legal right to acquire, own and sell the Receivables;

(ii) the Depositor is duly qualified to do business as a foreign limited liability company in good standing and has obtained all necessary licenses and approvals in each jurisdiction in which the failure to so qualify or to obtain such licenses and approvals would materially and adversely affect the performance by the Depositor of its obligations under, or the validity or enforceability of, this Trust Agreement, any of the other Transaction Documents to which the Depositor is a party, the Receivables, the Notes or the Certificates;

(iii) the Depositor has the power and authority to execute, deliver and perform its obligations under this Trust Agreement and the other Transaction Documents to which it is a party, and the Depositor has the power and authority to sell, assign, transfer and convey the property to be sold and transferred to and deposited with the Trust and has duly authorized such transfer and deposit by all necessary limited liability company action, and the execution, delivery and performance of this Trust Agreement and the other Transaction Documents to which the Depositor is a party have been duly authorized by the Depositor by all necessary limited liability company action;

(iv) the execution, delivery and performance by the Depositor of this Trust Agreement and the other Transaction Documents to which the Depositor is a party, the consummation of the transactions contemplated hereby and thereby and the fulfillment of the terms hereof and thereof will not conflict with, result in a breach of any of the terms and provisions of or constitute (with or without notice or lapse of time or both) a default under the certificate of formation or limited liability company agreement of the Depositor or any material indenture, agreement, mortgage, deed of trust or other instrument to which the Depositor is a party or by which the Depositor is bound or to which any of its properties are subject, or result in the creation or imposition of any lien upon any of its properties pursuant to the terms of any such indenture, agreement, mortgage, deed of trust or other instrument (other than pursuant to this Trust Agreement), or violate any law, order, rule or regulation applicable to the Depositor or its properties of any federal or State regulatory body, court, administrative agency or other governmental instrumentality having jurisdiction over the Depositor or any of its properties;

(v) there are no proceedings or investigations pending or, to the knowledge of the Depositor, threatened against the Depositor before any court, regulatory body, administrative agency or other governmental instrumentality having jurisdiction over the Depositor or its properties (A) asserting the invalidity of this Trust Agreement, the Sale and Servicing Agreement, the Indenture, any of the other Transaction Documents, the Notes or the Certificates, (B) seeking to prevent the issuance of the Notes or the Certificates or the consummation of any of the transactions contemplated by this Trust Agreement, the Sale and Servicing Agreement, the Indenture or any of the other Transaction Documents, (C) seeking any determination or ruling that would materially and adversely affect the performance by the Depositor of its obligations under, or the validity or enforceability of, this Trust Agreement, the Sale and Servicing Agreement, the Indenture, any of the other Transaction Documents, the Receivables, the Notes or the Certificates, or (D) that would adversely affect the federal tax attributes or Applicable Tax State franchise or income tax attributes of the Trust or of the Notes or the Certificates; and

(vi) the representations and warranties of the Depositor in Section 3.1 of the Receivables Purchase Agreement are true and correct.

Section 2.11 Federal Income Tax Matters. The Certificateholders acknowledge that it is their intent and that they understand it is the intent of the Depositor and the Servicer that, for purposes of federal income, State and local income and franchise tax and any other income taxes, the Trust will be treated either as a disregarded entity under Treasury Regulation Section 301.7701-3 or as a partnership, and that the Certificateholders will be treated as partners in that partnership. The Certificateholders by acceptance of a Certificate agree to such treatment and agree to take no action inconsistent with such treatment. For each calendar quarter, other than periods in which there is only one Certificateholder:

(i) net income of the Trust for any calendar quarter as determined for federal income tax purposes (and each item of income, gain, credit, loss or deduction entering into the computation thereof) shall be allocated among the Certificateholders as of the first day following the end of such quarter in proportion to their Certificate Percentage Interest on such date; and

(ii) net losses of the Trust, if any, for any calendar quarter as determined for federal income tax purposes (and each item of income, gain, credit, loss or deduction entering into the computation thereof) shall be allocated among the Certificateholders as of the first day following the end of such quarter in proportion to their Certificate Percentage Interest on such date.

The Depositor is authorized to modify the allocations in this Section 2.11 if necessary or appropriate, in its sole discretion, for the allocations to reflect fairly the economic income, gain, credit, loss or deduction to the Certificateholders or as otherwise required by the Code.

ARTICLE III

CERTIFICATES AND TRANSFER OF INTERESTS

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

Section 3.2 The Certificates. The Certificates shall be issued in one or more registered, definitive, physical certificates, substantially in the form set forth in Exhibit A. The Certificates may be in printed or typewritten form and shall be executed on behalf of the Trust by manual or facsimile signature of an Authorized 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 validly issued and entitled to the benefits of this Trust 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.

If Transfer of the Certificates is permitted pursuant to this Section 3.2 and Section 3.4, a transferee of a Certificate shall become a Certificateholder, and shall be entitled to the rights and subject to the obligations of a Certificateholder hereunder upon such transferee’s acceptance of a Certificate duly registered in such transferee’s name pursuant to Section 3.4.

Section 3.3 Authentication of Certificates. Concurrently with the initial sale of the Receivables to the Trust pursuant to the Sale and Servicing Agreement, the Owner Trustee shall cause the Certificates to be executed on behalf of the Trust, authenticated and delivered to or upon the written order of the Depositor, signed by its president, any vice president, any assistant vice president, its treasurer, any assistant treasurer, its secretary or any assistant secretary, without further limited liability company action by the Depositor. No Certificate shall entitle its Holder to any benefit under this Trust 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 by manual signature, which 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. Upon issuance, authentication and delivery pursuant to the terms hereof, the Certificates will be entitled to the benefits of this Trust Agreement.

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

(a) The Owner Trustee initially shall be the registrar (the “Certificate Registrar”) for the purpose of registering Certificates and Transfers of Certificates as herein provided. The Certificate Registrar shall cause to be kept, at the office or agency maintained pursuant to Section 3.8, a register (the “Certificate Register”) in which, subject to such reasonable regulations as it may prescribe, the Certificate Registrar shall provide for the registration of Certificates and the registration of Transfers of Certificates. Upon any resignation of any Certificate Registrar, the Owner Trustee shall, upon receipt of written instructions from the Depositor, promptly appoint a successor.

(b) The Certificates may not be acquired with the plan assets of any (i) “employee benefit plan” (as defined in Section 3(3) of ERISA) subject to the fiduciary requirements of ERISA, (ii) “plan” described in Section 4975(e)(1) of the Code, including individual retirement accounts and ▇▇▇▇▇ plans, that is subject to the provisions of Section 4975 of the Code or (iii) employee benefit plan or arrangement not subject to Title I of ERISA or Section 4975 of the Code whose acquisition of a Certificate would constitute or result in a violation of any applicable law that is substantially similar to Title I of ERISA or Section 4975 of the Code (each of (i) through (iii), a “Plan”). Each Certificateholder, by its acceptance of a Certificate, shall be deemed to have represented and warranted that such Certificateholder is not a Plan and is not a Person acting on behalf of a Plan or a Person using the assets of a Plan to effect the transfer of such Certificate.

Any person who is not an affiliate of the Seller and acquires more than 49.9% of the Certificates will be deemed to represent that it is not a party in interest (within the meaning of ERISA) or a disqualified person (within the meaning of Section 4975(e)(2) of the Code) with respect to any Plan, other than a Plan that it sponsors for the benefit of its employees, and that no Plan with respect to which it is a party in interest has or will acquire any interest in the Notes.

To the extent permitted under applicable law (including, but not limited to, ERISA), neither the Owner Trustee nor the Certificate Registrar shall be under any liability to any Person for any registration of transfer of any Certificate that is in fact not permitted or for taking any other action with respect to such Certificate under the provisions of this Trust Agreement so long as such transfer was registered by the Owner Trustee or the Certificate Registrar in accordance with this Trust Agreement.

(c) Upon surrender for registration of Transfer of any Certificate at the office or agency of the Certificate Registrar to be maintained as provided in Section 3.8, and upon compliance with any provisions of this Trust Agreement relating to such Transfer, the Owner Trustee shall execute on behalf of the Trust and the Owner Trustee shall authenticate and deliver to the Certificateholder making such surrender, in the name of the designated transferee or transferees, one or more new Certificates in any authorized denomination evidencing the same aggregate interest in the Trust. Each Certificate presented or surrendered for registration of Transfer or exchange shall be accompanied by a written instrument of transfer and accompanied by IRS Form ▇-▇ ▇▇▇, ▇-▇ ECI or W-9, as applicable, in form satisfactory to the Owner Trustee and the Certificate Registrar, duly executed by the Certificateholder or his attorney duly authorized in writing. Each Certificate presented or surrendered for registration of Transfer or exchange shall be canceled and subsequently disposed of by the Certificate Registrar in accordance with its customary practice. 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 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) As a condition to the registration of any Transfer of any Certificate:

(i) the prospective transferee shall be required to represent in writing to the Owner Trustee, the Depositor and the Certificate Registrar that it has neither acquired nor will it transfer any Certificate it purchases (or any interest therein) or cause any such Certificate (or any interest therein) to be marketed on or through an “established securities market” within the meaning of Section 7704(b)(1) of the Code, including, without limitation, an over-the-counter-market or an interdealer quotation system that regularly disseminates firm buy or sell quotations;

(ii) the prospective transferee shall be required to represent in writing to the Owner Trustee, the Depositor and the Certificate Registrar that it either (A) is not, and will not become, a partnership, Subchapter S corporation or grantor trust for United States federal income tax purposes or (B) is such an entity, but none of the direct or indirect beneficial owners of any of the interests in such transferee have allowed or caused, or will allow or cause, 50% or more (or such other percentage as the transferor may establish prior to the time of such proposed transfer) of the value of such interests to be attributable to such transferee’s ownership of Certificates;

(iii) the prospective transferee shall be required to represent in writing to the Owner Trustee, the Depositor and the Certificate Registrar that it is not a Plan and is not a Person acting on behalf of a Plan or a Person using the assets of a Plan to effect the transfer of such Certificate;

(iv) the Certificateholder provides to the Owner Trustee and the Depositor an opinion of independent counsel that such action will not cause the Issuing Entity to be treated as an association (or publicly traded partnership) taxable as a corporation for federal income tax purposes;

(v) such transferee or assignee agrees to take positions for tax purposes consistent with the tax positions agreed to be taken by the Certificateholder; and

(vi) in connection with any transfer of less than all of the interests in the Certificates, the transferor and transferee shall specify the respective interests in the Certificates to be held by the transferor and transferee, which interests may be determined by a formula or on any other basis agreed by the transferor and transferee. No Certificate (other than the Certificates issued to and held by the Depositor) may be subdivided upon transfer or exchange in a manner such that the resulting Certificate represents less than a 2.00% fractional undivided interest in the Issuing Entity (or such other amount as the Depositor may determine in order to prevent the Issuing Entity from being treated as a “publicly traded partnership” under Section 7704 of the Code, but in no event less than a 1.00% fractional undivided interest in the Issuing Entity).

(e) No Certificateholder shall Transfer any Certificate initially held by it unless such Transfer is made pursuant to an effective registration statement or otherwise in accordance with the requirements under the Securities Act and effective registration or qualification under applicable State securities laws, or is made in a transaction which does not require such registration or qualification. If a Transfer is to be made in reliance upon an exemption from the Securities Act and under applicable State securities laws, (i) the Certificate Registrar may require an Opinion of Counsel reasonably satisfactory to the Certificate Registrar and the Depositor substantially to the effect that such Transfer may be made pursuant to an exemption from the Securities Act and applicable State securities laws and describing the applicable exemption and the basis therefor, which Opinion of Counsel shall not be an expense of the Certificate Registrar, the Depositor or the Owner Trustee, and (ii) the Certificate Registrar may require the transferee to execute a certification acceptable to and in form and substance satisfactory to the Certificate Registrar and the Depositor setting forth the facts surrounding such Transfer.

(f) No Transfer of any Certificate shall be permitted, recognized or recorded unless the Depositor has consented in writing to such Transfer, which consent may be withheld in the sole discretion of the Depositor; provided, however, that no such consent of the Depositor shall be required where the proposed transferee is, and at the time of such Transfer will be, a Certificateholder.

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 and the Owner Trustee such security or indemnity as may be required by them to hold each of the Trust, the Certificate Registrar and the Owner Trustee harmless, then, in the absence of notice to the Trust, the

Certificate Registrar or the Owner Trustee that such Certificate has been acquired by a “protected purchaser” (as defined in the Relevant UCC), the Owner Trustee shall execute on behalf of the Trust and the Owner Trustee shall authenticate and deliver, in exchange for, or in lieu of, any such mutilated, destroyed, lost or stolen Certificate, as the case may be, a replacement Certificate, as the case may be, of like tenor and Certificate Percentage Interest. If, after the delivery of such replacement Certificate or payment of a destroyed, lost or stolen Certificate pursuant to the proviso to the preceding sentence, a “protected purchaser” (as defined in the Relevant UCC) of the original Certificate in lieu of which such replacement Certificate was issued presents for payment such original Certificate, the Trust and the Owner Trustee shall be entitled to recover such replacement Certificate (or such payment) from the Person to whom such replacement Certificate 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” (as defined in the Relevant UCC), 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.

(b) Upon the issuance of any replacement Certificate under this Section 3.5, 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 connection with such issuance and any other reasonable expenses (including the fees and expenses of the Owner Trustee) related thereto.

(c) Every replacement 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 at any time enforceable by anyone, and shall be entitled to all the benefits of this Trust Agreement equally and proportionately with any and all other Certificates duly issued hereunder.

(d) 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 Owners. Prior to due presentation of a Certificate for registration of transfer, the Owner Trustee, the Certificate Registrar and any Paying Agent may treat the Person in whose name such Certificate is registered in the Certificate Register (as of the day of determination) as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 5.2 and for all other purposes whatsoever, and none of the Owner Trustee, the Certificate Registrar or any Paying Agent shall be bound by any notice to the contrary.

Section 3.7 Access to List of Certificateholders’ Names and Addresses.

Section 5.1 Establishment of Certificate Payment Account. Pursuant to Section 4.1 of the Sale and Servicing Agreement, the Servicer has agreed to establish, on or before the Closing Date, and maintain in the name of the Owner Trustee at an Eligible Institution (which shall initially be the Owner Trustee) a segregated trust account designated as the “CarMax Auto Owner Trust 20[ ]-[ ] Trust Account” (the “Certificate Payment Account”). The Certificate Payment Account shall be held in trust for the benefit of the Certificateholders. Except as expressly provided in Section 3.9, the Certificate Payment Account shall be under the sole dominion and control of the Owner Trustee. All monies deposited from time to time in the Certificate Payment Account pursuant to the Sale and Servicing Agreement or the Indenture shall be applied as provided in this Trust Agreement, the Sale and Servicing Agreement and the Indenture. The amounts on deposit in the Certificate Payment Account shall not be invested.

Section 5.2 Application of Trust Funds.

(a) On each Distribution Date, upon receipt of written instructions from the Servicer pursuant to Section 4.1(c) of the Sale and Servicing Agreement, the Owner Trustee shall, or, if the Owner Trustee is not the Paying Agent, shall direct the Paying Agent to, distribute to the Certificateholders, in proportion to each Certificateholder’s Certificate Percentage Interest, amounts deposited in the Certificate Payment Account on such Distribution Date pursuant to Section 4.1(c) of the Sale and Servicing Agreement and Section 2.8 of the Indenture with respect to such Distribution Date.

(b) On each Distribution Date, the Owner Trustee shall, or, if the Owner Trustee is not the Paying Agent, the Owner Trustee shall direct the Paying Agent to, make available to each Certificateholder the statement provided to the Owner Trustee by the Servicer pursuant to Section 4.9 of the Sale and Servicing Agreement with respect to such Distribution Date.

(c) In the event that any withholding tax is imposed on any Trust payment (or any allocation of income) to a Certificateholder, such tax shall reduce the amount otherwise distributable to the Certificateholder in accordance with this Section 5.2. The Owner Trustee and each Paying Agent are hereby authorized and directed to retain from amounts otherwise distributable to the Certificateholders sufficient funds for the payment of any such withholding tax that is legally owed by the Trust (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 Owner Trustee may withhold such amounts in accordance with this Section 5.2. If a Certificateholder wishes to apply for a refund of any such withholding tax, the Owner Trustee shall reasonably cooperate with such Certificateholder in making such claim so long as such Certificateholder agrees to reimburse the Owner Trustee for any out-of-pocket expenses incurred.

Section 5.3 Method of Payment. Subject to Section 5.2(c), distributions required to be made to Certificateholders on any Distribution Date shall be made to each Certificateholder of record on the preceding Record Date either by wire transfer, in immediately available funds, to the account of such Holder at a bank or other entity having appropriate facilities therefor, if such Certificateholder shall have provided to the Certificate Registrar and the Paying Agent appropriate written instructions at least five (5) Business Days prior to such Distribution Date and such Certificateholder is the Depositor or, if not, by check mailed to such Certificateholder at the address of such Holder appearing in the Certificate Register. Notwithstanding the foregoing, the final distribution in respect of any Certificate (whether on the Final Scheduled Maturity Date or otherwise) will be payable only upon presentation and surrender of such Certificate at the office or agency maintained for that purpose by the Certificate Registrar pursuant to Section 3.8.

Section 5.4 No Segregation of Monies; No Interest. Subject to Section 5.1 and Section 5.2, monies received by the Owner Trustee hereunder need not be segregated in any manner except to the extent required by law, the Indenture[, the Swap Agreement] or the Sale and Servicing Agreement and may be deposited under such general conditions as may be prescribed by law, and the Owner Trustee shall not be liable for any interest thereon.

Section 5.5 Accounting and Reports to the Noteholders, Certificateholders, the Internal Revenue Service and Others. The Owner Trustee shall, based on information provided by the Seller, (i) maintain (or cause to be maintained) the books of the Trust on the basis of a fiscal year ending on the last day of February and based on the accrual method of accounting, (ii) deliver to each Certificateholder, as may be required by the Code and applicable Treasury Regulations, such information as may be required (including Schedule K-1) to enable such Certificateholder to prepare its federal and State income tax returns, (iii) file such tax returns relating to the Trust (including a partnership information return, IRS Form 1065) 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 partnership for federal income tax purposes, (iv) cause such tax returns to be signed in the manner required by law and (v) 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. The Owner Trustee, on behalf of the Trust, shall elect under Section 1278 of the Code to include in income currently any market discount that accrues with respect to the Receivables. The Owner Trustee, on behalf of the Trust, shall not make the election provided under Section 754 of the Code.

The Owner Trustee may satisfy its obligations with respect to this Section 5.5 by retaining, on behalf of the Trust, at the expense of the Seller, a firm of independent public accountants (the “Accountants”) selected by the Seller. The Owner Trustee, on behalf of the Trust, may require the Accountants to provide to the Owner Trustee, on or before March [15], 20[ ], a letter in form and substance satisfactory to the Owner Trustee as to whether any federal tax withholding on Certificates is then required and, if required, the procedures to be followed with respect thereto to comply with the requirements of the Code. The Accountants shall be required to update such letter in each instance that any additional tax withholding is subsequently required or any previously required tax withholding shall no longer be required. The Owner Trustee shall be deemed to have discharged its obligations pursuant to this Section 5.5 upon its retention of the Accountants, and the Owner Trustee shall not have any liability with respect to the default or misconduct of the Accountants.

Section 5.6 Signature on Returns; Tax Matters Partner.

(a) The Owner Trustee shall sign, on behalf of the Trust, the tax returns of the Trust.

(b) The Depositor, as a Certificateholder, shall be designated the “tax matters partner” of the Trust pursuant to Section 6231(a)(7)(A) of the Code and applicable Treasury Regulations.

TERMINATION

Section 9.1 Termination of Trust Agreement.

(a) This Trust Agreement (other than the provisions of Article VIII) shall terminate and be of no further force or effect and the Trust shall dissolve upon the earlier of (i) the payment to the Servicer, the Noteholders[, the Swap Counterparty] and the Certificateholders of all amounts required to be paid to them pursuant to the terms of the Indenture, the Sale and Servicing Agreement[, the Swap Agreement] and Article V and (ii) the Distribution Date next succeeding the month which is one year after the maturity or other liquidation of the last Receivable and the disposition of any amounts received upon liquidation of any property remaining in the Trust. The bankruptcy, liquidation, dissolution, death or incapacity of any Certificateholder shall not operate to terminate this Trust Agreement or the Trust, 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 Owner Trust Estate or otherwise affect the rights, obligations and liabilities of the parties hereto.

(b) No Certificateholder shall be entitled to revoke or terminate the Trust.

(c) Notice of any termination of the Trust, specifying the Distribution Date upon which the Certificateholders shall surrender their Certificates to the Paying Agent for payment of the final distribution and cancellation, shall be given by the Owner Trustee by letter to Certificateholders mailed within five (5) Business Days of receipt of notice of such termination from the Servicer, stating (i) the Distribution Date upon or with respect to which final payment of the Certificates shall be made upon presentation and surrender of the Certificates at the office of the Paying Agent therein specified, (ii) the amount of any such final payment and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the office of the Paying Agent therein specified.

Subject to applicable escheat laws, any funds remaining in the Trust after exhaustion of such remedies shall be distributed by the Owner Trustee to the Certificateholders in proportion to each Certificateholder’s Certificate Percentage Interest.

(d) Upon the winding up of the Trust, in accordance with Section 3808 of the Statutory Trust Statute, and its termination, the Owner Trustee shall, at the written direction of the Depositor, cause the Certificate of Trust to be canceled by filing a certificate of cancellation with the Secretary of State in accordance with the provisions of Section 3810 of the Statutory Trust Statute.

If such corporation or banking association 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 10.1 the combined capital and surplus of such corporation or banking association 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 10.1, the Owner Trustee shall resign immediately in the manner and with the effect specified in Section 10.2.

Section 10.2 Resignation or Removal of Owner Trustee. The Owner Trustee may at any time resign and be discharged from the trusts hereby created by giving written notice thereof to the Administrator and the Depositor. Upon receiving such notice of resignation, the Administrator shall promptly appoint a successor Owner Trustee (acceptable to the Depositor) by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning Owner Trustee and one copy to the successor Owner Trustee. If no successor Owner Trustee shall have been so appointed and have accepted appointment within thirty (30) days after the giving of such notice of resignation, the resigning Owner Trustee may petition any court of competent jurisdiction for the appointment of a successor Owner Trustee.

If at any time the Owner Trustee shall cease to be eligible in accordance with the provisions of Section 10.1 and shall fail to resign after written request therefor by the Administrator, or if at any time the Owner Trustee shall be legally unable to act, or shall be

adjudged bankrupt or insolvent, or a receiver of the Owner Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Owner Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, or the Owner Trustee shall otherwise become incapable of acting, then the Administrator shall remove the Owner Trustee. If the Administrator shall remove the Owner Trustee under the authority of the immediately preceding sentence, the Administrator shall promptly appoint a successor Owner Trustee (acceptable to the Depositor) by written instrument, in duplicate, one copy of which instrument shall be delivered to the removed Owner Trustee and one copy to the successor Owner Trustee.

Any resignation or removal of the Owner Trustee and appointment of a successor Owner Trustee pursuant to this Section 10.2 shall not become effective until acceptance of appointment by the successor Owner Trustee pursuant to Section 10.3 and payment of all fees and expenses owed to the outgoing Owner Trustee. The Administrator shall provide notice of such resignation or removal of the Owner Trustee to the Depositor, the Certificateholders, the Indenture Trustee, the Noteholders[, the Swap Counterparty] and the Rating Agencies.

Section 10.3 Successor Owner Trustee. Any successor Owner Trustee appointed pursuant to Section 10.2 shall execute, acknowledge and deliver to the Administrator and to its predecessor Owner Trustee an instrument accepting such appointment under this Trust Agreement, and thereupon, subject to the payment of all fees and expenses owed to the predecessor Owner Trustee, the resignation or removal of the predecessor Owner Trustee shall become effective and such successor Owner Trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor under this Trust Agreement, with like effect as if originally named as Owner Trustee. The predecessor Owner Trustee shall, upon payment of its fees and expenses, deliver to the successor Owner Trustee all documents, statements and monies held by it under this Trust Agreement, and the Administrator and the predecessor Owner Trustee shall execute and deliver such instruments and do such other things as may reasonably be required for fully and certainly vesting and confirming in the successor Owner Trustee all such rights, powers, duties and obligations.

No successor Owner Trustee shall accept appointment as provided in this Section 10.3 unless, at the time of such acceptance, such successor Owner Trustee shall be eligible pursuant to Section 10.1.

Any successor Owner Trustee appointed pursuant to this Section 10.3 shall file an amendment to the Certificate of Trust with the Secretary of State reflecting the name and principal place of business of such successor in the State of Delaware.

Upon acceptance of appointment by a successor Owner Trustee pursuant to this Section 10.3, the Administrator shall mail notice of such appointment to all Certificateholders, the Indenture Trustee, the Noteholders[, the Swap Counterparty] and the Rating Agencies. If the Administrator shall fail to mail such notice within ten (10) days after acceptance of appointment by the successor Owner Trustee, the successor Owner Trustee shall cause such notice to be mailed at the expense of the Administrator.

The Owner Trustee shall provide the Administrator (who shall promptly forward to the Rating Agencies) with prior written notice of any such transaction.

(b) If at the time such successor or successors by consolidation, merger or conversion to the Owner Trustee shall succeed to the trusts created by this Trust Agreement any of the Certificates shall have been authenticated but not delivered, any such successor to the Owner Trustee may adopt the certificate of authentication of any predecessor trustee and deliver such Certificates so authenticated, and in case at that time any of the Certificates shall not have been authenticated, any such successor to the Owner Trustee may authenticate such Certificates either in the name of any predecessor trustee or in the name of the successor to the Owner Trustee. In all such cases such certificates shall have the full force which the Certificates or this Trust Agreement provide that the certificate of the Owner Trustee shall have.

Section 10.5 Appointment of Co-Trustee or Separate Trustee.

(a) Notwithstanding any other provisions of this Trust Agreement to the contrary, 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 may execute and deliver an instrument to appoint one or more Persons approved by the Owner Trustee to act as co-trustee or co-trustees, jointly with the Owner Trustee, or separate trustee or separate trustees, of all or any part of the Owner Trust Estate, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Owner Trust Estate, or any part thereof, and, subject to the other provisions of this Section 10.5, 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 fifteen (15) days after the receipt by it of a request so to do, the Owner Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee under this Trust Agreement shall be required to meet the terms of eligibility as a successor trustee under Section 10.1 and no notice of the appointment of any co-trustee or separate trustee shall be required under Section 10.3.

(b) Each separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i) all rights, powers, duties and obligations conferred or imposed upon the Owner Trustee shall be conferred or imposed upon and exercised or performed by the Owner Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee shall not be authorized to act separately without the Owner Trustee joining in such act), except to the extent that under any law of any

jurisdiction in which any particular act or acts are to be performed the Owner Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title 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 Trust Agreement shall be personally liable by reason of any act or omission of any other trustee under this Trust Agreement; 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 Trust Agreement and the conditions of this Article X. 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 Trust Agreement, specifically including every provision of this Trust 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 constitute the Owner Trustee its agent or attorney-in-fact with full power and authority, to the extent permitted by law, to do any lawful act under or in respect of this Trust 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.
