TRUST PROPERTY

2.1 Conveyance of Trust Property.

(a) In consideration of the Trust’s delivery to, or upon the written order of, the Depositor of authenticated Notes, in authorized denominations in aggregate principal amounts equal to the Initial Note Balance, and authenticated Certificates, the Depositor hereby irrevocably sells, transfers, assigns, sets over and otherwise conveys to the Trust, without recourse (subject to the obligations herein), all right, title and interest of the Depositor, whether now owned or hereafter acquired, in, to and under the following:

(i) the Receivables;

(ii) all amounts received on or in respect of the Receivables after the Cutoff Date;

(iii) the security interests in the Financed Vehicles granted by the Obligors pursuant to the Receivables and any other interest of the Depositor in such Financed Vehicles;

(iv) all proceeds from claims on or refunds of premiums with respect to physical damage, theft, GAP, credit life or credit disability insurance policies relating to the Financed Vehicles or the Obligors;

(v) the Receivable Files;

(vi) the Collection Account, the Note Payment Account, the Certificate Payment Account and the Reserve Account and all amounts, securities, financial assets, investments and other property deposited in or credited to the Collection Account, the Note Payment Account and the Certificate Payment Account and all proceeds thereof;

(vii) all rights of the Depositor under the Receivables Purchase Agreement, including the right to require the Seller to repurchase Receivables from the Depositor;

(viii) the right to realize upon any property (including the right to receive future Liquidation Proceeds) that shall have secured a Receivable and have been repossessed by or on behalf of the Trust; and

(ix) all present and future claims, demands, causes of action and choses in action in respect of any or all of the foregoing and all payments on or under and all proceeds of every kind and nature whatsoever in respect of any or all of the foregoing, including all proceeds of the conversion thereof, voluntary or involuntary, into cash or other liquid property; all accounts, general intangibles, chattel paper, instruments, documents, money, investment property, deposit accounts, letters of credit, letter-of-credit rights, insurance proceeds, condemnation awards, rights to payment of any and every kind and other forms of obligations; and all other property which at any time constitutes all or part of or is included in the proceeds of any of the foregoing.

(b) The Depositor and the Trust intend that the transfer of the Trust Property contemplated by Section 2.1(a) constitute a sale of the Trust Property, conveying good title to the Trust Property, from the Depositor to the Trust. If such transfer is deemed to be a pledge to secure the payment of the Notes, however, the Depositor hereby grants to the Trust a first priority security interest in all of the Depositor’s right, title and interest in, to and under the Trust Property, and all proceeds thereof, to secure the payment of the Notes, and in such event, this Agreement shall constitute a security agreement under applicable law.

(c) The sale, transfer, assignment and conveyance of the Trust Property made under Section 2.1(a) shall not constitute and is not intended to result in an assumption by the Trust of any obligation of the Depositor or the Seller to the Obligors or any other Person in connection with the Receivables and the other Trust Property or any obligation of the Depositor or the Seller under any agreement, document or instrument related thereto.

2.2 Representations and Warranties from Receivables Purchase Agreement. The Seller has made to the Depositor the representations and warranties as to the Receivables and the pool of Receivables set forth in Sections 3.3 and 3.4 of the Receivables Purchase Agreement. The Trust shall be deemed to have relied on such representations and warranties in accepting the Receivables. The representations and warranties set forth in Section 3.3 and 3.4 of the Receivables Purchase Agreement speak as of the execution and delivery of this Agreement, except to the extent otherwise provided, but shall survive the sale, transfer, assignment and conveyance of the Receivables to the Trust pursuant to this Agreement and the pledge of the Receivables to the Indenture Trustee pursuant to the Indenture. Pursuant to Section 2.1, the Depositor has sold, transferred, assigned, set over and otherwise conveyed to the Trust, as part of the Trust Property, its rights under the Receivables Purchase Agreement, including its right to require the Seller to repurchase Receivables in accordance with the Receivables Purchase Agreement upon a breach of the representations and warranties set forth in Section 3.4 of the Receivables Purchase Agreement.

2.3 Representations and Warranties of the Depositor as to the Receivables and the Pool of Receivables.

(a) Representations and Warranties as to the Pool of Receivables. The Depositor makes the following representations and warranties as to the pool of Receivables on which the Trust shall be deemed to have relied in accepting the pool of Receivables. The representations and warranties speak as of the Closing Date, except to the extent otherwise provided, but shall survive the sale, transfer, assignment and conveyance of the pool of Receivables to the Trust pursuant to this Agreement and the pledge of the Receivables to the Indenture Trustee pursuant to the Indenture:

(i) Receivable Schedule. The representations and warranties set forth in Section 3.3(a) of the Receivables Purchase Agreement are true and correct in all material respects as of the Closing Date, except to the extent otherwise provided therein.

(ii) Security Interest Matters. This Agreement creates a valid and continuing “security interest” (as defined in the Relevant UCC) in the Receivables in favor of the Trust, which security interest is prior to all other Liens and is enforceable as such as against creditors of and purchasers from the Depositor. The Receivables constitute “tangible chattel paper” or “electronic chattel paper” (each as defined in the Relevant UCC). The Depositor owns and has good and marketable title to the Receivables free and clear of any Lien, claim or encumbrance of any Person. The Depositor has caused or will cause prior to the Closing Date the filing of all appropriate financing statements in the proper filing offices in the appropriate jurisdictions under applicable law necessary to perfect the security interest in the Receivables granted to the Trust under this Agreement. Other than the security interest granted to the Trust under this Agreement, the Depositor has not pledged, assigned, sold, granted a security interest in or otherwise conveyed any of the Receivables. The Depositor has not authorized the filing of and is not aware of any financing statements against the Depositor that include a description of collateral covering the Receivables other than any financing statement relating to the security interest granted to the Trust under this Agreement or that has been terminated. The Depositor is not aware of any material judgment or tax lien filings against the Depositor. The security interest of the Seller in each Financed Vehicle has been validly assigned by the Depositor to the Trust. Neither the Depositor nor a custodian or vaulting agent thereof has communicated, nor will they communicate, an “authoritative copy” (as defined in the Relevant UCC) of any Receivable to any Person other than the Servicer, the Trust or the Indenture Trustee.

(iii) Financing Statements. All financing statements filed or to be filed against the Depositor in favor of the Indenture Trustee (as assignee of the Trust) contain a statement substantially to the following effect: “A purchase of or security interest in any collateral described in this financing statement will violate the rights of the Indenture Trustee.”

(b) Representations and Warranties as to the Receivables. The Depositor makes the following representations and warranties as to the Receivables on which the Trust shall be deemed to have relied in accepting the pool of Receivables. The representations and

warranties speak as of the Closing Date, except to the extent otherwise provided, but shall survive the sale, transfer, assignment and conveyance of the pool of Receivables to the Trust pursuant to this Agreement and the pledge of the Receivables to the Indenture Trustee pursuant to the Indenture:

(i) Characteristics of Receivables. The representations and warranties as to the Receivables set forth in Sections 3.4(a) through (d), (f), (h), (j), and (m) through (t) of the Receivables Purchase Agreement are true and correct as of the Closing Date, except to the extent otherwise provided therein.

(ii) Security Interest in Financed Vehicles. Immediately prior to the transfer of the Receivables by the Depositor to the Trust, each Receivable was secured by a valid, binding and enforceable first priority perfected security interest in favor of the Seller in the related Financed Vehicle, or all necessary and appropriate actions shall have been commenced that would result in the valid perfection of a first priority security interest in favor of the Seller in the Financed Vehicle, which security interest has been validly assigned by the Seller to the Depositor pursuant to the Receivables Purchase Agreement and by the Depositor to the Trust hereunder.

(iii) No Waiver. No provision of any Receivable has been waived in such a manner that such Receivable fails to meet all of the representations and warranties made by the Depositor in this Section 2.3(b) with respect thereto.

(iv) No Liens. The Depositor has no knowledge of any liens or claims that have been filed, including liens for work, labor or materials or for unpaid State or federal taxes, relating to any Financed Vehicle that are prior to, or equal or coordinate with, the security interest in such Financed Vehicle created by the related Receivable.

(v) Title. Immediately prior to the transfer of the Receivables contemplated by Section 2.1(a), the Depositor had good and marketable title to the Receivables free and clear of any Lien, claim or encumbrance of any Person and, immediately upon such transfer, the Trust shall have good and marketable title to the Receivables free and clear of any Lien, claim or encumbrance of any Person, other than the Depositor pursuant to the Receivables Purchase Agreement. The Depositor has not sold, transferred, assigned or pledged any Receivable to any Person other than the Trust. The Depositor has not created, incurred or suffered to exist any Lien, encumbrance or security interest on any Receivable except for the Lien of the Receivables Purchase Agreement, this Agreement and the Indenture.

(vi) Valid Assignment. The Depositor has not entered into any agreement with any account debtor that prohibits, restricts or conditions the assignment of the Receivables.

2.4 Repurchase by Depositor upon Breach; Dispute Resolution.

(a) Investigation of Breach. If the Depositor (i) has knowledge of a breach of a representation or warranty made in Section 2.3(b), (ii) receives notice from the Trust, the Owner Trustee or the Indenture Trustee of a breach of a representation or warranty made in

Section 2.3(b), (iii) receives a written request to repurchase a Receivable due to an alleged breach of a representation and warranty in Section 2.3(b) from the Owner Trustee, the Indenture Trustee, any Verified Note Owner or any Noteholder (which repurchase request shall provide sufficient detail so as to allow the Seller or the Depositor to reasonably investigate the alleged breach of the representations and warranties in Section 2.3(b); provided, that with respect to a repurchase request from a Noteholder or a Verified Note Owner, such repurchase request shall initially be provided to the Indenture Trustee) for a Receivable (each, a “Repurchase Request”) or (iv) receives a final report from the Asset Representations Reviewer that indicates that the Asset Representations Reviewer has determined that a test procedure under the Asset Representations Review Agreement has not been satisfied with respect to a representation or warranty set forth in Section 2.3(b) hereof or Section 3.4 of the Receivables Purchase Agreement for a Receivable, then, in each case, the Depositor will investigate the Receivable to confirm the breach and determine if the breach materially and adversely affects the interests of the Issuer or the Noteholders in any Receivable. None of the Servicer, the Issuer, the Owner Trustee, the Indenture Trustee, the Asset Representations Reviewer or the Administrator will have an obligation to investigate whether a breach of any representation or warranty has occurred or whether any Receivable is required to be repurchased under Section 2.4(b).

(b) Repurchase of Receivables. The Depositor, the Servicer or the Administrator (on behalf of the Trust), as the case may be, shall inform the other parties to this Agreement, the Seller and the Indenture Trustee promptly, in writing, upon the discovery of any breach or failure to be true of the representations and warranties set forth in Section 2.3(b). If such breach or failure shall not have been cured by the close of business on the last day of the Collection Period which includes the 60^th day after the date on which the Depositor becomes aware of such breach or failure, and the Depositor determines that such breach or failure materially and adversely affects the interest of the Trust or the Noteholders in a Receivable, the Depositor shall repurchase such Receivable from the Trust on the Distribution Date immediately following such Collection Period. Any such breach or failure will be deemed not to have a material and adverse effect if such breach or failure has not affected the ability of the Issuer to receive and retain payment in full on such Receivable. In consideration of the repurchase of a Receivable hereunder, the Depositor shall remit the Purchase Amount of such Receivable in the manner specified in Section 4.5. Upon any such repurchase, the Trust shall, without further action, be deemed to transfer, assign, set-over and otherwise convey to the Depositor, without recourse, representation or warranty, all of the right, title and interest of the Trust in, to and under such repurchased Receivable and all other related assets described in Section 2.1(a). The Trust shall execute such documents and instruments of transfer or assignment and take such other actions as shall reasonably be requested by the Depositor to effect the conveyance of such Receivable pursuant to this Section 2.4(b). The sole remedy of the Trust with respect to a breach of the Depositor’s representations and warranties set forth in Section 2.3(b) shall be to require the Depositor to repurchase Receivables pursuant to this Section 2.4(b).

(c) Unfulfilled Repurchase Demands. In the event the Depositor fails to repurchase a Receivable pursuant to Section 2.4(b), or fails to cause the Seller to repurchase a Receivable pursuant to Section 3.5(c) of the Receivables Purchase Agreement, within 180 days of the delivery of a Repurchase Request and such Repurchase Request has not been resolved, the alleged breach has not otherwise been cured or the related Receivable has not otherwise been repurchased, paid-off or otherwise satisfied, the party that provided the Repurchase Request

pursuant to Section 2.4(a) (the “Requesting Party”) may refer the Repurchase Request to an ADR Proceeding, at its discretion, pursuant to Section 2.4(d) by filing in accordance with ADR Rules and providing a notice to the Depositor and the Seller; provided, however, that any such referral of a Repurchase Request shall be made (i) within the applicable statute of limitations period and (ii) within 30 days of the delivery of the Repurchase Response Notice indicating that the related Repurchase Request has not been resolved. The Indenture Trustee shall have no obligation to pursue or otherwise be involved in resolving any Repurchase Request, including any such request that is the subject of an ADR Proceeding, unless it is directed to do so by Noteholders or Note Owners of at least 5% of the Controlling Class, and such Noteholders or Note Owners shall have offered to the Indenture Trustee security or indemnity satisfactory to it against the reasonable costs, expenses, disbursements, advances and liabilities that might be incurred by it, its agents and its counsel in compliance with such direction. For the avoidance of doubt, if the Indenture Trustee does not agree to pursue or otherwise be involved in resolving any Repurchase Request, the related Noteholder or Verified Note Owner may independently pursue dispute resolution in respect of such Repurchase Request in accordance with Section 2.4(d). The Indenture Trustee shall be under no obligation to monitor repurchase activity or to independently determine which Repurchase Requests remain unresolved after 180 days.

(d) Dispute Resolution.

(i) General. If a Requesting Party provides notice of a referral of a Repurchase Request to an ADR Proceeding, the Depositor shall have at least 30 days to respond to such notice. Each ADR Proceeding shall take place in New York, New York. Under no circumstances will the Indenture Trustee, in its individual capacity, be liable for any costs, expenses and/or liabilities that could be allocated to the Requesting Party in any ADR Proceeding.

(ii) Confidentiality. Neither the Depositor nor the Seller will be required to produce personally identifiable customer information for purposes of any mediation or arbitration. The existence and details of any unresolved Repurchase Request, any informal meetings, mediations or arbitration proceedings, the nature and amount of any relief sought or granted, any offers or statements made and any discovery taken in the proceeding will be confidential, privileged and inadmissible for any purpose in any other mediation, arbitration, litigation or other proceeding. The parties will keep this information confidential and will not disclose or discuss it with any third party (other than a party’s attorneys, experts, accountants and other advisors, as reasonably required in connection with the mediation or arbitration proceeding under this Section 2.4(d)), except as required by law, regulatory requirement or court order. If a party to a mediation or arbitration proceeding receives a subpoena or other request for information from a third party (other than a governmental regulatory body) for confidential information of the other party to the mediation or arbitration proceeding, the recipient will promptly notify the other party and will provide the other party with the opportunity to object to the production of its confidential information. Nothing in this Section 2.4(d)(ii) shall prevent the Noteholders or Note Owners from exercising their rights under Section 7.5(b) of the Indenture or the Servicer or the Depositor from complying with its disclosure requirements under Item 1121 of Regulation AB.

(iii) Mediation. If the Requesting Party chooses to refer the Repurchase Request to Mediation, the following provisions shall apply:

(1) The Depositor and the Requesting Party shall agree on a neutral mediator within 15 days of the acknowledgement of the notice set forth in Section 2.4(d)(i); provided, that the mediator shall satisfy each of the following conditions:

a. the mediator shall be selected from a list of neutral mediators maintained by the ADR Facilitator;

b. the mediator shall be an attorney admitted to practice law in the State of New York; and

c. the mediator shall be an attorney specializing in commercial litigation with at least 15 years of experience;

provided, however, that if the Depositor and the Requesting Party do not agree on a mediator, a mediator shall be selected by the ADR Facilitator in accordance with ADR Rules for appointment of a mediator.

(2) The Mediation shall commence no later than 15 Business Days following selection of a mediator, and shall conclude within 30 days of the start of Mediation.

(3) The Depositor and the Requesting Party shall mutually agree upon the allocation of the expenses incurred in connection with the Mediation; provided, however, that if the Depositor and the Requesting Party do not agree on the allocation of expenses, the expenses shall be determined in accordance with ADR Rules.

(4) If the Depositor and the Requesting Party fail to agree at the completion of the Mediation, the Requesting Party may submit the Repurchase Request to Arbitration in accordance with Section 2.4(d)(iv) or may seek adjudication of the Repurchase Request in court.

(iv) Arbitration. If the Requesting Party refers the Repurchase Request to Arbitration, the following provisions shall apply:

(1) The Depositor shall provide a notice of the commencement of such Arbitration and instructions for other Noteholders or Note Owners to participate in such Arbitration to the Servicer for inclusion in the Form 10-D related to the monthly period in which the arbitration proceeding commences.

(2) The Repurchase Request shall be referred to a panel of three arbitrators (the “Panel”) to be selected in accordance with the ADR Rules; provided, that each arbitrator shall satisfy each of the following conditions: (i) the arbitrator shall be selected from a list of neutral arbitrators maintained by the ADR Facilitator, (ii) the arbitrator shall be an attorney admitted to practice law in the State of New York; and (iii) the arbitrator shall be an attorney specializing in commercial litigation with at least 15 years of experience.

(3) The following procedural time limits shall apply to the Arbitration:

a. discovery shall be completed within 30 days of appointment of the third arbitrator;

b. the evidentiary hearing on the merits shall commence no later than 60 days following the appointment of the third arbitrator, and shall proceed for no more than 10 consecutive business days with equal time allotted to each side for the presentation of direct evidence and cross examination; and

c. the Panel shall render its decision on the Repurchase Request within 90 days of the selection of the panel;

provided, that in each case, the Panel may modify such limits if, based on the facts and circumstances of the particular dispute, good cause exists, there is an unavoidable delay or with the consent of all of the parties.

(4) The following limitations on the Arbitration proceeding shall apply:

a. each party shall be limited to two witness depositions not to exceed five hours;

b. each party shall be limited to two interrogatories;

c. each party shall be limited to one document request; and

d. each party shall be limited to one request for admissions;

provided, that in each case, the Panel may modify such time limits if, based on the facts and circumstances of the particular dispute, good cause exists, there is an unavoidable delay or with the consent of all of the parties.

(5) Any briefs submitted in the Arbitration shall be no more than 10 pages each and shall be limited to (i) initial statements of the case, (ii) discovery motions and (iii) a pre-hearing brief.

(6) The Panel shall decide the Repurchase Request in accordance with this Agreement and the Receivables Purchase Agreement, including the provisions set forth in Section 10.3, including choice-of-law provisions, and may not modify or change the Transaction Documents in any way or award remedies not consistent with the Transaction Documents.

(7) The Panel shall not be permitted to award punitive or special damages.

(8) The Panel shall determine the allocation of the expenses of the Arbitration, including attorneys’ fees, between the Depositor and the Requesting Party.

(9) Judgment on the award will be entered in any court having jurisdiction.

(10) Once the Panel makes a decision with respect to a Receivable, such decision shall be binding on the Trust and each other party identified or described in the Receivables Purchase Agreement or the other Transaction Documents as having an interest as owner, trustee, secured party or holder of the Receivables, Notes or Certificates as to such Receivable, and such Receivable may not be subject to an additional ADR Proceeding. By selecting Arbitration, the Requesting Party is giving up the right to xxx in court, including the right to a trial by jury.

2.5 Custody of Receivable Files. To assure uniform quality in servicing the Receivables and to reduce administrative costs, the Trust, upon the execution and delivery of this Agreement, hereby revocably appoints the Servicer as its agent, and the Servicer hereby accepts such appointment, to act as custodian on behalf of the Trust and the Indenture Trustee of the following documents or instruments, which are hereby constructively delivered to the Indenture Trustee, as pledgee of the Trust pursuant to the Indenture with respect to each Receivable (collectively, a “Receivable File”):

(i) the original, executed copy of such Receivable, or a single “authoritative copy” (as defined in the Relevant UCC), as applicable;

(ii) the original credit application with respect to such Receivable fully executed by the related Obligor or a photocopy thereof or a record thereof on a computer file or disc or on microfiche;

(iii) the original certificate of title for the related Financed Vehicle or such other documents that the Seller or the Servicer shall keep on file, in accordance with its customary practices and procedures, evidencing the security interest of the Seller in such Financed Vehicle;

(iv) documents evidencing the commitment of the related Obligor to maintain physical damage insurance covering the related Financed Vehicle; and

(v) any and all other documents (including any computer file or disc or microfiche) that the Seller or the Servicer shall keep on file, in accordance with its customary practices and procedures, relating to such Receivable, the related Obligor or the related Financed Vehicle.

The Servicer hereby acknowledges receipt, on behalf of the Trust and the Indenture Trustee, of all the documents and instruments necessary for the Servicer to act as the agent of the Trust and the Indenture Trustee for the purposes set forth in this Section 2.5, including the documents referred to herein.

2.6 Duties of Servicer as Custodian.

(a) Safekeeping. The Servicer, in its capacity as custodian, shall hold, or maintain, as applicable, the Receivable Files for the benefit of the Trust and the Indenture Trustee and maintain such accurate and complete accounts, records and computer systems pertaining to each Receivable File as shall enable the Servicer and the Trust to comply with the terms and provisions of this Agreement, the Indenture Trustee to comply with the terms and conditions of the Indenture and the Asset Representations Reviewer to comply with the terms and conditions of the Asset Representations Review Agreement. In performing its duties as custodian, the Servicer shall act in accordance with its customary servicing practices, using the degree of skill and attention that the Servicer exercises with respect to the files relating to comparable motor vehicle retail installment sale contracts that the Servicer services for itself or others. The Servicer shall conduct, or cause to be conducted, in accordance with its customary practices and procedures, periodic audits of the Receivable Files held by it under this Agreement, and of the related accounts, records and computer systems, in such a manner as shall enable the Trust or the Indenture Trustee to verify the accuracy of the Servicer’s record keeping. The Servicer shall promptly report to the Owner Trustee and the Indenture Trustee any failure on its part to hold the Receivable Files and maintain its accounts, records and computer systems as herein provided and promptly take appropriate action to remedy any such failure. Nothing herein shall be deemed to require an initial review or any periodic review by the Trust, the Owner Trustee or the Indenture Trustee of the Receivable Files, and none of the Trust, the Owner Trustee or the Indenture Trustee shall be liable or responsible for any action or failure to act by the Servicer in its capacity as custodian hereunder.

The Servicer shall maintain each Receivable File at one of the locations listed in Schedule 2 or at such other location as shall be specified to the Trust, the Owner Trustee and the Indenture Trustee by written notice not later than ninety (90) days after any change in location. The Servicer shall make available to the Trust, the Owner Trustee, the Indenture Trustee and, to the extent the Servicer shall have received an Asset Representations Review Notice, the Asset Representations Reviewer, or its duly authorized representatives, attorneys or auditors, a list of locations of the Receivable Files, the Receivable Files, and the related accounts, records, and computer systems maintained by the Servicer, at such times as the Trust or the Indenture Trustee shall instruct.

(c) Release of Documents. As soon as practicable after receiving written instructions from the Indenture Trustee or, to the extent the Servicer shall have received an Asset Representations Review Notice, from the Asset Representations Reviewer, the Servicer shall release any document in the Receivable Files to the Indenture Trustee or the Asset Representations Reviewer or such Person’s agent or designee, as the case may be, at such place as the Indenture Trustee or the Asset Representations Reviewer may reasonably designate.

(d) Title to Receivables. The Servicer shall not at any time have or in any way attempt to assert any interest in any Receivable held by it as custodian hereunder or in the related Receivable File other than for collecting or enforcing such Receivable for the benefit of the Trust. The entire equitable interest in such Receivable and the related Receivable File shall at all times be vested in the Trust.

2.7 Instructions; Authority to Act. The Servicer shall be deemed to have received proper instructions with respect to the Receivable Files upon its receipt of written instructions signed by an Authorized Officer. A certified copy of excerpts of authorizing resolutions of the Board of Directors of the Indenture Trustee shall constitute conclusive evidence of the authority of any such Authorized Officer to act and shall be considered in full force and effect until receipt by the Servicer of written notice to the contrary given by the Indenture Trustee.

2.8 Indemnification by the Custodian. The Servicer, in its capacity as custodian, shall indemnify and hold harmless the Trust, the Owner Trustee and the Indenture Trustee and each of their respective officers, directors, employees and agents from and against any and all liabilities, obligations, losses, compensatory damages, payments, claims, actions, suits, costs or expenses (including legal fees if any) of any kind whatsoever that may be imposed on, incurred or asserted against the Trust, the Owner Trustee or the Indenture Trustee or any of their respective officers, directors, employees and agents as the result of any act or omission by the Servicer relating to the maintenance and custody of the Receivable Files, including those incurred in connection with any action, claim or suit brought to enforce the Indenture Trustee’s right to indemnification; provided, however, that the Servicer shall not be liable hereunder to the Owner Trustee or the Indenture Trustee, as applicable, to the extent that such liabilities, obligations, losses, compensatory damages, payments, claims, actions, suits, costs or expenses result from the willful misfeasance, bad faith or negligence of the Owner Trustee or the Indenture Trustee, as applicable.

2.9 Effective Period and Termination. The Servicer’s appointment as custodian shall become effective as of the Cutoff Date and shall continue in full force and effect until terminated pursuant to this Section 2.9. If the Servicer shall resign as Servicer under Section 7.6, or if all of the rights and obligations of the Servicer shall have been terminated under Section 8.1, the appointment of the Servicer as custodian hereunder may be terminated (i) by the Trust, with the consent of the Indenture Trustee, (ii) by the Holders of Notes evidencing not less than 25% of the Note Balance of the Controlling Class or, if the Notes have been paid in full, by the Holders of Certificates evidencing not less than 25% of the aggregate Certificate

As soon as practicable after any termination of such appointment, the Servicer shall deliver, or cause to be delivered, the Receivable Files and the related accounts and records maintained by the Servicer to the Indenture Trustee, the Indenture Trustee’s agent or the Indenture Trustee’s designee, as the case may be, at such place as the Indenture Trustee may reasonably designate or, if the Notes have been paid in full, at such place as the Owner Trustee may reasonably designate.

ARTICLE III

ADMINISTRATION AND SERVICING OF RECEIVABLES AND

OTHER TRUST PROPERTY

3.1 Duties of Servicer. The Servicer shall administer the Receivables with reasonable care. The Servicer’s duties shall include, but not be limited to, the collection and posting of all payments, responding to inquiries by Obligors on the Receivables, or by federal, State or local governmental authorities, investigating delinquencies, reporting federal income tax information to Obligors, furnishing monthly and annual statements to the Administrator, the Owner Trustee and the Indenture Trustee with respect to distributions and providing collection and repossession services in the event of Obligor default. In performing its duties as Servicer hereunder, the Servicer shall service the Receivables in accordance with its customary servicing practices, using the degree of skill and attention that the Servicer exercises with respect to all comparable motor vehicle retail installment sale contracts that it services for itself or others. The Servicer will have full power and authority to do any and all things in connection with managing, servicing, administration and collection of the Receivables that it may deem necessary or desirable. Subject to the foregoing and to Section 3.2, the Servicer shall follow its customary standards, policies, practices and procedures in performing its duties hereunder as Servicer. Without limiting the generality of the foregoing, the Servicer is hereby authorized and empowered to execute and deliver, on behalf of itself, the Depositor, the Trust, the Administrator, the Owner Trustee, the Indenture Trustee, the Certificateholders, the Noteholders or any one or more of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge, and all other comparable instruments, with respect to the Receivables or the Financed Vehicles, all in accordance with this Agreement; provided, however, that, notwithstanding the foregoing, the Servicer shall not, except pursuant to an order from a court of competent jurisdiction, release an Obligor from payment of any unpaid amount under any Receivable or waive the right to collect the unpaid balance (including accrued interest) of any Receivable from the related Obligor, except in connection with a de minimis deficiency which the Servicer would not attempt to collect in accordance with its customary procedures, in which event the Servicer shall indemnify the Trust for such deficiency. If the Servicer shall commence a legal proceeding to enforce a Receivable, the Trust shall thereupon be deemed to have automatically assigned such Receivable to the Servicer, which assignment shall be solely for purposes of collection. If in any enforcement suit or legal proceeding it shall be held that the Servicer may not enforce a Receivable on the ground that it shall not be a real party in interest or a holder entitled to enforce such Receivable, the Trust shall (or the Administrator on behalf of the Trust shall), at the Servicer’s expense and written direction, take steps to enforce such Receivable, including bringing suit in its name or the names of the Indenture Trustee, the

Certificateholders, the Noteholders or any of them. The Trust shall execute and deliver to the Servicer any powers of attorney and other documents as shall be prepared by the Servicer and reasonably necessary or appropriate to enable the Servicer to carry out its servicing and administrative duties hereunder. The Servicer, at its expense, shall obtain on behalf of the Trust all licenses, if any, required by the laws of any jurisdiction to be held by the Trust in connection with ownership of the Receivables and shall make all filings and pay all fees as may be required in connection therewith during the term hereof. If the Servicer fails to perform its obligations under this Agreement and the Indenture Trustee or any other successor Servicer is appointed as Servicer in accordance with Section 8.2, such successor Servicer shall be responsible for the Servicer’s duties under this Agreement except as specified in Section 8.2; provided, however, that such successor Servicer shall not be liable for the terminated Servicer’s failure to perform such obligations. Notwithstanding anything to the contrary in this Agreement or any other Transaction Document, the Servicer shall not be liable for any failure or delay in the performance of its obligations or the taking of any action hereunder or under any other Transaction Document (and such failure or delay shall not constitute a breach of any Transaction Document or an Event of Servicing Termination) if such failure or delay arises from compliance by the Servicer with any law or court order, the direction of a regulatory authority or regulatory guidance.

3.2 Collection and Allocation of Receivable Payments. The Servicer shall make reasonable efforts to collect all payments called for under the terms and provisions of the Receivables as and when the same shall become due in accordance with the standard of care required by Section 3.1. The Servicer shall allocate collections on or in respect of the Receivables between principal and interest in accordance with the customary servicing practices and procedures it follows with respect to all comparable motor vehicle retail installment sale contracts that it services for itself or others. The Servicer may grant extensions, rebates, deferrals, amendments, modifications, temporary reductions in payments or adjustments with respect to any Receivable in accordance with its customary servicing practices; provided, however, that if the Servicer (i) extends the date for final payment by the Obligor of any Receivable beyond the last day of the Collection Period immediately prior to the Final Scheduled Maturity Date or (ii) reduces the APR or unpaid principal balance with respect to any Receivable, other than as required by applicable law (including, without limitation, by the Servicemembers Civil Relief Act) or court order or at the direction of a regulatory authority or in accordance with regulatory guidance, it will promptly purchase such Receivable in the manner provided in Section 3.7. The Servicer may, in its discretion (but only in accordance with its customary standards, policies, practices and procedures), waive any late payment charge or any other fee that may be collected in the ordinary course of servicing a Receivable.

3.3 Realization upon Receivables. The Servicer shall use reasonable efforts on behalf of the Trust, in accordance with the standard of care required under Section 3.1, to repossess or otherwise convert the ownership of each Financed Vehicle securing a Defaulted Receivable; provided, however, that the Servicer may elect not to repossess a Financed Vehicle if in its sole discretion it determines that repossession will not increase the aggregate Liquidation Proceeds or that the proceeds ultimately recoverable with respect to such Receivable would be increased by forbearance or that repossessing such Financed Vehicle would otherwise not be consistent with the Servicer’s customary servicing practices. In taking such action, the Servicer shall follow such customary practices and procedures as it shall deem necessary or advisable in

its servicing of comparable motor vehicle retail installment sale contracts and as are otherwise consistent with the standard of care required under Section 3.1. The Servicer shall be entitled to recover all reasonable expenses, including external costs of collection, incurred by it in connection with collection of any Defaulted Receivables and in the course of repossessing and liquidating a Financed Vehicle into cash proceeds, but only out of the cash proceeds of such Financed Vehicle and any deficiency obtained from the related Obligor. If a Financed Vehicle shall have suffered damage, the Servicer shall not expend funds in connection with the repair or the repossession of such Financed Vehicle unless it shall determine in its discretion that such repair and/or repossession will increase the Liquidation Proceeds received with respect to the related Receivable.

3.4 Physical Damage Insurance. The Servicer shall follow its customary practices and procedures to determine whether or not each Obligor shall have maintained physical damage insurance covering the related Financed Vehicle.

3.5 Maintenance of Security Interests in Financed Vehicles. The Servicer shall take such steps, in accordance with the standard of care required under Section 3.1, as are necessary to maintain perfection of the security interest created by each Receivable in the related Financed Vehicle at all times. The Trust hereby authorizes the Servicer, and the Servicer hereby agrees, to take such steps as are necessary to re-perfect such security interest on behalf of the Trust and the Indenture Trustee in the event the Servicer receives notice of, or otherwise has actual knowledge of, the fact that such security interest is not perfected as a result of the relocation of a Financed Vehicle or for any other reason. The Servicer shall not release, in whole or in part, any security interest in a Financed Vehicle created by the related Receivable except as permitted herein or in accordance with its customary standards, policies, practices and procedures.

3.6 Amendment of Receivable Terms. The Servicer shall not impair in any material respect the rights of the Depositor, the Trust, the Owner Trustee, the Indenture Trustee, the Certificateholders or the Noteholders in the Receivables or, except as permitted under Section 3.2, otherwise amend or alter the terms of the Receivables if, as a result of such amendment or alteration, the interests of the Depositor, the Trust, the Owner Trustee, the Indenture Trustee, the Certificateholders or the Noteholders hereunder would be materially adversely affected.

3.7 Purchase by Servicer upon Breach. The Depositor, the Servicer or the Administrator (on behalf of the Trust), as the case may be, shall inform the other parties to this Agreement, the Seller and the Indenture Trustee promptly, in writing, upon the discovery of any breach of Sections 3.2, 3.5 or 3.6. If such breach shall not have been cured by the close of business on the last day of the Collection Period which includes the 60^th day after the date on which the Servicer becomes aware of, or receives written notice from the Depositor or the Administrator (on behalf of the Trust) of, such breach, and such breach materially and adversely affects the interest of the Trust in a Receivable, the Servicer shall purchase such Receivable from the Trust on the Distribution Date following such Collection Period; provided, however, that with respect to a breach of Section 3.2, the Servicer shall purchase the affected Receivable from the Trust at the end of the Collection Period in which such breach occurs. Any such breach or failure will be deemed not to have a material and adverse effect if such breach or failure has not

affected the ability of the Issuer to receive and retain payment in full on such Receivable. In consideration of the purchase of a Receivable hereunder, the Servicer shall remit the Purchase Amount of such Receivable in the manner specified in Section 4.5. The sole remedy of the Trust, the Administrator, the Owner Trustee, the Indenture Trustee, the Noteholders and the Certificateholders with respect to a breach of Sections 3.2, 3.5 or 3.6 shall be to require the Servicer to purchase Receivables pursuant to this Section 3.7. None of the Administrator, the Owner Trustee or the Indenture Trustee shall have any duty to conduct an affirmative investigation as to the occurrence of any condition requiring the purchase of any Receivable pursuant to this Section 3.7.

3.8 Servicing Compensation and Reimbursement.

(a) Servicing Fee. The Servicer shall receive the Monthly Servicing Fee for servicing the Receivables. The Monthly Servicing Fee for any Collection Period shall equal the product of one-twelfth (1/12) of the Servicing Rate and the Pool Balance as of the first day of such Collection Period (or, in the case of the initial Collection Period, as of the Cutoff Date); provided, however, that the Monthly Servicing Fee payable to a successor Servicer other than the Indenture Trustee may equal such other amount as may be determined in accordance with Section 8.2(a). The Servicer shall also be entitled to all Supplemental Servicing Fees collected (from whatever source) on the Receivables. The Servicer shall pay all expenses incurred by it in connection with its activities hereunder (including the fees and expenses of the Owner Trustee, including reasonable fees and expenses of its attorneys and any custodian appointed by the Owner Trustee, the fees and expenses of independent accountants, agents and other experts as such trustee may employ in connection with the exercise and performance of its rights and its duties under the Transaction Documents, taxes imposed on the Servicer, expenses incurred in connection with distributions and reports to the Certificateholders and the Noteholders, and the fees, expenses and other amounts owing to the Asset Representations Reviewer pursuant to the Asset Representations Review Agreement), except expenses incurred in connection with realizing upon Receivables under Section 3.3.

(b) Reimbursement. On each Payment Date, the Indenture Trustee shall remit to the Servicer an amount equal to any funds deposited in the Collection Account during any preceding Collection Period (and not previously included in any amounts paid to the Servicer under this Section 3.8(b)) that constitute Unrelated Amounts. Unrelated Amounts to be reimbursed hereunder shall be paid to the Servicer on the related Payment Date pursuant to Section 2.8(a) and Section 5.4(b) of the Indenture upon certification by the Servicer of such amounts and the provision of such information to the Indenture Trustee. The Servicer may deduct from Available Collections all Unrelated Amounts to the extent such Unrelated Amounts have not been previously reimbursed to the Servicer.

3.9 Monthly Servicer’s Certificate. On or before the Determination Date immediately preceding each Distribution Date, the Servicer shall deliver to the Depositor, the Seller, the Owner Trustee, the Indenture Trustee and each Paying Agent, with a copy to the Rating Agencies, a certificate of a Servicing Officer substantially in the form of Exhibit A (a “Servicer’s Certificate”) and attached to a Servicer’s report containing all information necessary to make the transfers and distributions pursuant to Sections 4.5, 4.6 and 4.7, together with the written statements to be furnished by the Indenture Trustee to the Certificateholders pursuant to

Section 4.9 and by the Indenture Trustee to the Noteholders pursuant to Section 4.9 and pursuant to Section 6.6 of the Indenture. The Servicer shall separately identify (by account number) in a written notice to the Depositor, the Owner Trustee and the Indenture Trustee the Receivables to be repurchased by the Depositor or to be purchased by the Servicer, as the case may be, on the Business Day preceding such Distribution Date, and, upon request of one of the foregoing parties, each Receivable which became a Defaulted Receivable during the related Collection Period. The Servicer shall deliver to the Rating Agencies any information, to the extent it is available to the Servicer, that the Rating Agencies reasonably request (and the initial Servicer shall specify in writing to the successor Servicer any such requests that remain unsatisfied during the servicing transition to the successor Servicer) in order to monitor the Trust.

Such access shall be afforded without charge, but only upon reasonable request and during normal business hours at the offices of the Servicer. Nothing in this Section 3.12 shall affect the obligation of the Servicer to observe any applicable law prohibiting disclosure of information regarding the Obligors, and the failure of the Servicer to provide access to information as a result of such obligation shall not constitute a breach of this Section 3.12.

The Servicer shall remit to the Collection Account all amounts (excluding, for the avoidance of doubt, any Supplemental Servicing Fees) received by the Servicer on or in respect of the Receivables (including Liquidation Proceeds and all amounts received by the Servicer in connection with the repossession and sale of a Financed Vehicle (whether or not the related Receivable has been classified as a Defaulted Receivable)) but excluding payments with respect to Purchased Receivables) as soon as practicable and in no event after the close of business on the second Business Day after such receipt; provided, however, that for so long as (i) CarMax is the Servicer, (ii) no Event of Servicing Termination shall have occurred and be continuing and (iii) CarMax’s short-term unsecured debt is rated at least “A-1” by S&P Global Ratings and “P-1” by Moody’s (the “Monthly Remittance Condition”), the Servicer may remit any such amounts received during any Collection Period to

the Collection Account in immediately available funds on the Business Day preceding the Distribution Date following such Collection Period (it being understood that the Monthly Remittance Condition has not been satisfied as of the Closing Date); provided further, that if any such amounts (including Liquidation Proceeds and all amounts received by the Servicer in connection with the repossession and sale of a Financed Vehicle (whether or not the related Receivable has been classified as a Defaulted Receivable)) are received in respect of a Receivable as to which there is an unreimbursed Simple Interest Advance, the Servicer shall retain such amounts to the extent of such unreimbursed Simple Interest Advance (and shall apply the amount retained to reimburse itself for such unreimbursed Simple Interest Advance) and shall remit the balance of such amounts to the Collection Account; and, provided further, that the Servicer shall, if it determines that it has made an Unreimbursed Servicer Advance, retain amounts received on or in respect of the Receivables to the extent set forth in Section 4.4(b). The Owner Trustee and the Indenture Trustee shall not be deemed to have knowledge of any event or circumstance under clauses (ii) or (iii) of the definition of Monthly Remittance Condition that would require daily remittance by the Servicer to the Collection Account unless the Owner Trustee or the Indenture Trustee, as applicable, has received notice of such event or circumstance at its Corporate Trust Office from the Depositor or the Servicer in an Officer’s Certificate or written notice of such event or circumstance from the Holders of Notes evidencing not less than 25% of the Note Balance of the Controlling Class or unless a Responsible Officer of the Owner Trustee or the Indenture Trustee, as applicable, has actual knowledge of such event or circumstance. The Servicer shall remit to the Collection Account on the Closing Date all amounts received by the Servicer on or in respect of the Receivables (including Liquidation Proceeds and all amounts received by the Servicer in connection with the repossession and sale of a Financed Vehicle (whether or not the related Receivable has been classified as a Defaulted Receivable)) during the period from but excluding the Cutoff Date to and including the second Business Day preceding the Closing Date.

4.3 Application of Collections. For purposes of this Agreement, all amounts (excluding, for the avoidance of doubt, any Supplemental Servicing Fees) received on or in respect of a Receivable during any Collection Period (including Liquidation Proceeds and all amounts received by the Servicer in connection with the repossession and sale of a Financed Vehicle (whether or not the related Receivable has been classified as a Defaulted Receivable) but excluding payments with respect to Purchased Receivables) shall be applied by the Servicer, as of the last day of such Collection Period, to interest and principal on such Receivable in accordance with the Simple Interest Method.

4.4 Simple Interest Advances and Unreimbursed Servicer Advances.

(a) If, as of the end of any Collection Period, one or more payments of Monthly P&I due under any Receivable (other than a Defaulted Receivable) outstanding at the end of such Collection Period shall not have been received by the Servicer and remitted to the Collection Account pursuant to Section 4.2, the Servicer may, at its option, make, on the Business Day preceding the Distribution Date immediately following such Collection Period, a Simple Interest Advance with respect to such Receivable, to the extent that the Servicer determines that such advances will be recoverable from subsequent collections or recoveries on the Receivables, by depositing in or crediting to the Collection Account the amount of Monthly P&I allocable to interest scheduled to have been paid during such Collection Period, assuming that such Receivable was paid on its due date, minus the amount of Monthly P&I actually received and allocated to interest, if any, with respect to such Receivable during such Collection Period.

(b) If the Servicer determines that it has made an Unreimbursed Servicer Advance, the Servicer shall reimburse itself for such Unreimbursed Servicer Advance from unrelated amounts received by the Servicer on or in respect of the Receivables (including Liquidation Proceeds and all amounts received by the Servicer in connection with the repossession and sale of a Financed Vehicle (whether or not the related Receivable has been classified as a Defaulted Receivable)); provided, however, that the Servicer shall furnish to the Indenture Trustee and the Owner Trustee, on or before the Distribution Date following the Collection Period during which such reimbursement is taken, a certificate of a Servicing Officer setting forth the basis for such determination, the amount of such Unreimbursed Servicer Advance, the Receivable with respect to which such Unreimbursed Servicer Advance was made and the installments or other proceeds with respect to which such reimbursement was taken.

4.5 Additional Deposits. The Depositor and the Servicer shall deposit or cause to be deposited in the Collection Account the aggregate Purchase Amount with respect to Purchased Receivables pursuant to Sections 2.4, 3.7 or 9.1. All such deposits described above with respect to a Collection Period shall be made in immediately available funds no later than noon, New York City time, on the Distribution Date following such Collection Period.

(ii) the Reserve Account Amount for the following Distribution Date (after giving effect to the withdrawal of the Reserve Account Draw Amount for such Distribution Date); and

(iii) the amount, if any, by which the Required Reserve Account Amount for the following Distribution Date exceeds the Reserve Account Amount for such Distribution Date (after giving effect to the withdrawal of the Reserve Account Draw Amount for such Distribution Date) (such excess, the “Reserve Account Deficiency”).

On each Distribution Date, the Servicer shall instruct the Indenture Trustee to transfer the Reserve Account Draw Amount, if any, for such Distribution Date from the Reserve Account to the Collection Account.

(d) On each Distribution Date, the Servicer shall instruct the Indenture Trustee (or, if the Indenture Trustee is not the Paying Agent, the Paying Agent) in writing to apply the Available Funds for such Distribution Date to make the payments and deposits set forth in Sections 2.8(a) or 5.4(b) of the Indenture, as applicable.

4.7 Reserve Account.

(a) The Servicer shall establish, on or before the Closing Date, and maintain with the Indenture Trustee in the name and for the benefit of the Trust at an Eligible Institution (which shall initially be the Indenture Trustee) a segregated trust account designated as the Reserve Account (the “Reserve Account”). The Reserve Account shall be held in trust for the benefit of the Noteholders and the Depositor. The Reserve Account shall be under the sole dominion and control of the Indenture Trustee; provided, however, that the Servicer may make deposits to and direct the Indenture Trustee in writing to make withdrawals from the Reserve Account in accordance with this Agreement and the Indenture. On the Closing Date, the Depositor shall deposit the Initial Reserve Account Deposit into the Reserve Account. All of the Depositor’s right, title and interest to the Reserve Account has been conveyed by the Depositor to the Trust pursuant to Section 2.1 and all amounts, securities, investments, financial assets and other property deposited in or credited to the Reserve Account shall be pledged by the Depositor to the Indenture Trustee for the benefit of the Noteholders (the “Reserve Account Property”). Pursuant to the Indenture, the Trust will pledge all of its right, title and interest in, to and under the Reserve Account and the Reserve Account Property to the Indenture Trustee on behalf of the Noteholders to secure its obligations under the Notes and the Indenture. The Depositor hereby grants to the Indenture Trustee on the Closing Date, as Indenture Trustee for the benefit of the Holders of the Notes, all of the Depositor’s right, title and interest in, to and under, whether now owned or existing or hereafter acquired or arising, the Reserve Account and the Reserve Account Property and all proceeds thereof.

(b) The Reserve Account Property shall, to the extent permitted by applicable law, rules and regulations, be invested, as directed in writing by the Servicer, by the bank or trust company then maintaining the Reserve Account in Permitted Investments (provided, that funds on deposit in the Reserve Account shall be invested in Permitted Investments meeting the requirements of 17 CFR Part 246.4(b)(2), as determined by the Servicer) that mature not later than the Business Day preceding the next Distribution Date. All such Permitted Investments shall be held to maturity. The Servicer acknowledges that upon its written request and at no additional cost, it has the right to receive notification after the completion of each such investment or the Indenture Trustee’s receipt of a broker’s confirmation. The Servicer agrees that such notifications shall not be provided by the Indenture Trustee hereunder, and the Indenture

Trustee shall make available, upon request and in lieu of notifications, periodic account statements that reflect such investment activity. No statement need be made available if no activity has occurred in the Reserve Account during such period. On any Distribution Date, all interest and other income (net of losses and investment expenses) on funds on deposit in the Reserve Account, to the extent that funds on deposit therein, as certified by the Servicer, exceed the Required Reserve Account Amount, shall, at the written direction of the Servicer, (i) first, be deposited into the Note Payment Account, for payment of principal of the Notes in the priority set forth in Section 2.8(d) of the Indenture, to the extent of any unfunded Regular Principal Distributable Amount, if any, on such Distribution Date (after giving effect to the application of Available Funds on such Distribution Date), (ii) second, be paid to the Asset Representations Reviewer, the Indenture Trustee or any other successor Servicer (to the extent such successor Servicer is not an Affiliate of CarMax), as applicable, to the extent of any unfunded amounts payable pursuant to Section 2.8(a)(xiii) of the Indenture, if any, on such Distribution Date (after giving effect to the application of Available Funds on such Distribution Date) and (iii) third, be distributed to the Depositor. If the Reserve Account is no longer to be maintained at the Indenture Trustee, the Servicer shall, with the Indenture Trustee’s assistance as necessary, promptly (and in any case within ten (10) calendar days or such longer period not to exceed thirty (30) calendar days as to which each Rating Agency may consent) cause the Reserve Account to be moved to an Eligible Institution. The Servicer shall promptly notify the Indenture Trustee and the Owner Trustee in writing of any change in the account number or location of the Reserve Account.

(i) any Reserve Account Property that is a “financial asset” (as defined in Section 8-102(a)(9) of the Relevant UCC) shall be physically delivered to, or credited to an account in the name of, the Eligible Institution maintaining the Reserve Account, in accordance with such institution’s customary procedures such that such institution establishes a “securities entitlement” in favor of the Indenture Trustee with respect thereto;

(ii) any Reserve Account Property that is held in deposit accounts shall be held solely in the name of the Indenture Trustee at one or more depository institutions having the Required Rating and each such deposit account shall be subject to the exclusive custody and control of the Indenture Trustee and the Indenture Trustee shall have sole signature authority with respect thereto; and

(iii) except for any deposit accounts specified in clause (ii) above, the Reserve Account shall only be invested in securities or in other assets which the Eligible Institution maintaining the Reserve Account agrees to treat as “financial assets” (as defined in Section 8-102(a)(9) of the Relevant UCC).

(d) If the Reserve Account Amount for any Distribution Date (after giving effect to the withdrawal of the Reserve Account Draw Amount for such Distribution Date) exceeds the Required Reserve Account Amount for such Distribution Date, the Servicer shall instruct the Indenture Trustee in writing to distribute the amount of such excess (i) first, to the Note Payment Account, for payment of principal of the Notes in the priority set forth in Section 2.8(d)

of the Indenture, to the extent of any unfunded Regular Principal Distributable Amount, if any, on such Distribution Date (after giving effect to the application of Available Funds on such Distribution Date), (ii) second, to be paid to the Asset Representations Reviewer, the Indenture Trustee or any other successor Servicer (to the extent such successor Servicer is not an Affiliate of CarMax), as applicable, to the extent of any unfunded amounts payable pursuant to Section 2.8(a)(xiii) of the Indenture, if any, on such Distribution Date (after giving effect to the application of Available Funds on such Distribution Date) and (iii) third, to the Depositor. The Indenture Trustee and the Owner Trustee hereby release, on each Distribution Date, their security interest in, to and under Reserve Account Property distributed to the Depositor.

(e) If the Note Balance, and all other amounts owing or to be distributed hereunder or under the Indenture or the Trust Agreement to the Noteholders or the Certificateholders, have been paid in full and the Trust has been terminated, any remaining Reserve Account Property shall be distributed to the Depositor.

4.8 Net Deposits. As an administrative convenience, unless the Servicer is required to remit collections on a daily basis pursuant to the first sentence of Section 4.2, the Depositor and the Servicer may make any remittance pursuant to this Article IV with respect to a Collection Period net of distributions or reimbursements to be made to the Depositor or the Servicer with respect to such Collection Period; provided, however, that such obligations shall remain separate obligations, no party shall have a right of offset and each such party shall account for all of the above described remittances and distributions as if the amounts were deposited and/or transferred separately.

4.9 Statements to Noteholders and Certificateholders. On or prior to each Determination Date, the Servicer shall provide to the Indenture Trustee (with copies to the Depositor, the Rating Agencies and each Paying Agent), for the Indenture Trustee to make available to each Note Owner as described below, and to the Indenture Trustee (with copies to the Depositor, the Rating Agencies and each Paying Agent), for the Indenture Trustee to make available to each Certificateholder of record as of the most recent Record Date, the Servicer’s Certificate.

The Indenture Trustee shall notify the Noteholders in writing of any changes in the address or means of access to the Internet website where the reports are accessible. The Indenture Trustee makes no representation or warranty as to the accuracy or completeness of such documents and will assume no responsibility therefor. For assistance with regard to this service, Note Owners can call the Indenture Trustee’s Bondholder Services Group at (000) 000-0000.

(e) No Violation. The execution, delivery and performance by the Servicer of this Agreement and the other Transaction Documents to which the Servicer 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 Servicer or any material indenture, agreement, mortgage, deed of trust or other instrument to which the Servicer is a party or by which the Servicer 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, or violate any law, order, rule or regulation applicable to the Servicer or its properties of any federal or State regulatory body, court, administrative agency or other governmental instrumentality having jurisdiction over the Servicer or any of its properties.

7.2 Liability of Servicer; Indemnities.

(a) The Servicer shall be liable in accordance herewith only to the extent of the obligations specifically undertaken by the Servicer under this Agreement.

(b) The Servicer shall indemnify, defend and hold harmless the Trust, the Owner Trustee, the Indenture Trustee, the Noteholders, the Certificateholders and the Depositor from and against all costs, expenses, losses, claims, actions, suits, damages and liabilities arising out of or incurred in connection with the use, ownership or operation by the Servicer or any Affiliate of the Servicer of a Financed Vehicle.

(d) The Servicer shall indemnify, defend and hold harmless the Trust, the Owner Trustee, the Indenture Trustee, the Noteholders, the Certificateholders and the Depositor from and against any loss, liability or expense incurred by reason of the Servicer’s willful misfeasance, bad faith or gross negligence in the performance of its duties under this Agreement or any other Transaction Document to which it is a party or by reason of a reckless disregard of its obligations and duties under this Agreement or any other Transaction Document to which it is a party.

(e) The Servicer shall indemnify, defend and hold harmless the Owner Trustee and the Indenture Trustee and their respective officers, directors, employees and agents from and against all costs, expenses, losses, claims, actions, suits, damages and liabilities arising out of or incurred in connection with the acceptance or performance of the trusts and duties contained herein and in the Trust Agreement, in the case of the Owner Trustee, and in the Indenture, in the case of the Indenture Trustee, except to the extent that such cost, expense, loss, claim, damage or liability (i) shall be due to the willful misfeasance, bad faith or gross negligence (except for errors in judgment) of the Owner Trustee or the Indenture Trustee, as applicable, (ii) in the case of the Owner Trustee, shall arise from the breach by the Owner Trustee of any of its representations or warranties set forth in the Trust Agreement, (iii) in the case of the Indenture Trustee, shall arise from the breach by the Indenture Trustee of any of its representations and warranties set forth in the Indenture or (iv) relates to any tax other than the taxes with respect to which either the Depositor or the Servicer shall be required to indemnify the Owner Trustee or the Indenture Trustee, as applicable.

Indemnification under this Section 7.2 by CarMax (or the successor Servicer, as applicable) as Servicer, with respect to the period such Person was (or was deemed to be) the Servicer, shall survive the termination of such Person as Servicer or a resignation by such Person as Servicer as well as the resignation or removal of the Owner Trustee or the Indenture Trustee and the termination of this Agreement and shall include the reasonable fees and expenses of counsel and expenses of litigation (including those incurred in connection with any action, claim or suit brought to enforce the Indenture Trustee’s right to indemnification) and the fees and expenses of the Owner Trustee and the Indenture Trustee. If the Servicer shall have made any indemnity payments pursuant to this Section 7.2 and the Person to or on behalf of whom such payments are made thereafter shall collect any of such amounts from others, such Person shall promptly repay such amounts to the Servicer, without interest.

7.3 Merger or Consolidation of, or Assumption of the Obligations of, Servicer. Any Person (i) into which the Servicer shall be merged or consolidated, (ii) resulting from any merger, conversion or consolidation to which the Servicer shall be a party or (iii) that shall succeed by purchase and assumption to all or substantially all of the business of the Servicer, which Person in any of the foregoing cases is an Eligible Servicer and executes an agreement of assumption to perform every obligation of the Servicer under this Agreement, shall be the successor to the Servicer under this Agreement without the execution or filing of any other document or any further act on the part of any of the parties to this Agreement; provided, however, that (x) the Servicer shall have delivered to the Depositor, the Owner Trustee and the Indenture Trustee an Officer’s Certificate and an Opinion of Counsel each stating that such merger, conversion, consolidation or succession and such agreement of assumption comply with this Section 7.3 and (y) the Servicer shall have delivered to the Depositor, the Owner Trustee and the Indenture Trustee an Opinion of Counsel either (A) stating that, in the opinion of such counsel, all financing statements and continuation statements and amendments thereto have been authorized and filed that are necessary to fully preserve and protect the interest of the Trust and the Indenture Trustee, respectively, in the Receivables, and reciting the details of such filings or referring to prior Opinions of Counsel in which such details are given, or (B) stating that, in the opinion of such counsel, no such action shall be necessary to fully preserve and protect such interest. The Servicer shall provide prior written notice of any merger, conversion, consolidation or succession pursuant to this Section 7.3 to the Rating Agencies. Notwithstanding anything to the contrary contained herein, the execution of the foregoing agreement of assumption and compliance with clauses (x) and (y) above shall be conditions to the consummation of the transactions referred to in clauses (i), (ii) and (iii) above.

7.4 Limitation on Liability of Servicer and Others.

(a) Neither the Servicer nor any of the directors, officers, employees or agents of the Servicer shall be under any liability to the Trust, the Noteholders or the Certificateholders for any action taken or for refraining from the taking of any action pursuant to this Agreement or for errors in judgment; provided, however, that this provision shall not protect the Servicer or

any such Person against any liability that would otherwise be imposed by reason of willful misfeasance or bad faith in the performance of duties or by reason of reckless disregard of obligations and duties under this Agreement, or by reason of negligence in the performance of duties under this Agreement (except for errors in judgment). The Servicer and its directors, officers, employees and agents may rely in good faith on the advice of counsel or on any document of any kind prima facie properly executed and submitted by any Person in respect of any matters arising under this Agreement.

(b) The Servicer shall not be under any obligation to appear in, prosecute or defend any legal action that shall not be incidental to its duties to service the Receivables in accordance with this Agreement and that in its opinion may involve it in any expense or liability; provided, however, that the Servicer may undertake any reasonable action that it may deem necessary or desirable in respect of this Agreement and the rights and duties of the parties to this Agreement and the interests of the Noteholders and the Certificateholders under this Agreement. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Servicer.

(c) The parties expressly acknowledge and consent to U.S. Bank National Association, acting in the capacity of Indenture Trustee and in the possible dual capacity of successor Servicer and Indenture Trustee. U.S. Bank National Association, may, in such dual or other capacity, discharge its separate functions fully, without hindrance or regard to conflict of interest principles, duty of loyalty principles or other breach of fiduciary duties to the extent that any such conflict or breach arises from the performance by U.S. Bank National Association, of express duties set forth in this Agreement in any of such capacities, all of which defenses, claims or assertions are hereby expressly waived by the other parties hereto and the Noteholders except in the case of gross negligence and willful misconduct by U.S. Bank National Association.

7.5 Delegation of Duties. The Servicer may at any time delegate its duties as servicer under this Agreement to third parties; provided, however, that no such delegation shall relieve the Servicer of its responsibilities with respect to such duties and the Servicer shall be solely responsible for the fees of any such third party.

Any such determination permitting the resignation of the Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Depositor, the Owner Trustee and the Indenture Trustee. No such resignation shall become effective until the Indenture Trustee or another successor Servicer shall have (i) assumed the obligations and duties of the Servicer in accordance with Section 8.2 and (ii) become the Administrator under the Administration Agreement pursuant to Section 20 thereof.

7.7 Servicer May Own Notes or Certificates. The Servicer, and any Affiliate of the Servicer, may, in its individual or any other capacity, become the owner or pledgee of Notes or Certificates with the same rights as it would have if it were not the Servicer or an

Affiliate of the Servicer, except as otherwise expressly provided herein (including in the definition of “Note Balance”) or in the other Transaction Documents. Except as otherwise expressly provided herein (including in the definition of “Note Balance”) or in the other Transaction Documents, Notes and Certificates so owned by or pledged to the Servicer or such Affiliate shall have an equal and proportionate benefit under the provisions of this Agreement and the other Transaction Documents, without preference, priority or distinction as among the Notes and the Certificates.

ARTICLE VIII

SERVICING TERMINATION

8.1 Events of Servicing Termination.

(a) The occurrence of any one of the following events shall constitute an event of servicing termination hereunder (each, an “Event of Servicing Termination”):

(i) any failure by the Servicer to deliver to the Owner Trustee, the Indenture Trustee, the Depositor, the Seller, each Paying Agent or the Rating Agencies the Servicer’s Certificate for any Collection Period, which failure shall continue unremedied beyond three (3) Business Days following the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Servicer by the Depositor, the Owner Trustee or the Indenture Trustee or to the Depositor, the Seller, the Servicer, the Owner Trustee and the Indenture Trustee by the Holders of Notes evidencing not less than 25% of the Note Balance of the Controlling Class, or any failure by the Servicer to make any required payment or deposit under this Agreement, which failure shall continue unremedied beyond five (5) Business Days following the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Servicer by the Depositor, the Owner Trustee or the Indenture Trustee or to the Depositor, the Seller, the Servicer, the Owner Trustee and the Indenture Trustee by the Holders of Notes evidencing not less than 25% of the Note Balance of the Controlling Class; or

(ii) any failure by the Servicer duly to observe or perform in any material respect any other covenant or agreement in this Agreement, which failure shall materially and adversely affect the rights of the Depositor or the Noteholders and shall continue unremedied for a period of sixty (60) days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Servicer by the Depositor, the Owner Trustee or the Indenture Trustee or to the Depositor, the Seller, the Servicer, the Owner Trustee and the Indenture Trustee by the Holders of Notes evidencing not less than 25% of the Note Balance of the Controlling Class; or

(iii) any representation or warranty of the Servicer made in this Agreement or in any certificate delivered pursuant hereto or in connection herewith, other than any representation and warranty relating to a Receivable that has been purchased by the Servicer, proving to have been incorrect in any material respect as of the time when the same shall have been made, and the circumstance or condition in respect of which such representation or warranty was incorrect shall not have been eliminated or otherwise

cured for a period of thirty (30) days after the date on which written notice of such circumstance or condition, requiring the same to be eliminated or cured, shall have been given to the Servicer by the Depositor, the Owner Trustee or the Indenture Trustee or to the Depositor, the Seller, the Servicer, the Owner Trustee and the Indenture Trustee by the Holders of Notes evidencing not less than 25% of the Note Balance of the Controlling Class; or

(iv) the entry of a decree or order by a court or agency or supervisory authority of competent jurisdiction for the appointment of a conservator, receiver, liquidator or trustee for the Servicer in any bankruptcy, insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceeding, or for the winding up or liquidation of its affairs, which decree or order continues unstayed and in effect for a period of sixty (60) consecutive days; or

(v) the consent by the Servicer to the appointment of a conservator, receiver, liquidator or trustee in any bankruptcy, insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceeding of or relating to the Servicer or relating to substantially all of its property, the admission in writing by the Servicer of its inability to pay its debts generally as they become due, the filing by the Servicer of a petition to take advantage of any applicable bankruptcy, insolvency or reorganization statute, the making by the Servicer of an assignment for the benefit of its creditors or the voluntary suspension by the Servicer of payment of its obligations.

If an Event of Servicing Termination shall have occurred and be continuing, the Indenture Trustee or the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class, in each case by notice then given in writing to the Depositor, the Administrator and the Servicer (with a copy to the Indenture Trustee and the Owner Trustee if given by the Noteholders), may terminate all of the rights and obligations of the Servicer under this Agreement; provided, however, that the indemnification obligations of the Servicer under Section 7.2 shall survive such termination. On or after the receipt by the Servicer of such written notice, all authority and power of the Servicer under this Agreement, whether with respect to the Notes, the Certificates, the Trust Property or otherwise, shall pass to and be vested in the Indenture Trustee or other successor Servicer appointed under Section 8.2; provided, however, that the Indenture Trustee or such other successor Servicer shall have no liability with respect to any obligation that was required to be performed by the terminated Servicer prior to the appointment of the Indenture Trustee or such other successor Servicer or any claim of any third party based on any alleged action or inaction of the terminated Servicer.

(b) The Indenture Trustee and the Owner Trustee shall have no obligation to notify the Noteholders, the Certificateholders or any other Person of the occurrence of any event specified in Section 8.1(a) prior to the continuance of such event through the end of any cure period specified in Section 8.1(a).

8.2 Indenture Trustee to Act; Appointment of Successor Servicer.

(a) Upon the resignation of the Servicer pursuant to Section 7.6 or the termination of the Servicer pursuant to Section 8.1, the Indenture Trustee shall be the successor

in all respects to the Servicer in its capacity as Servicer under this Agreement and shall be subject to all the obligations and duties placed on the Servicer by the terms and provisions of this Agreement; provided, however, that the Indenture Trustee, as successor Servicer, shall not, in any event, make any Simple Interest Advances pursuant to Section 4.4, shall have no obligations pursuant to Section 3.7 with respect to the repurchase of Receivables and shall have no obligations pursuant to Section 3.8 with respect to the fees and expenses of the Owner Trustee, the fees and expenses of the Owner Trustee’s attorneys, the fees and expenses of any custodian appointed by the Owner Trustee, the fees and expenses of independent accountants or expenses incurred in connection with distributions and reports to the Certificateholders or the Noteholders and the fees, expenses and other amounts owing to the Asset Representations Reviewer or pay any indemnities owed pursuant to Sections 2.8, 7.2(b), 7.2(d) or 7.2(e). As compensation therefor, the Indenture Trustee shall be entitled to such compensation (whether payable out of the Collection Account or otherwise) as the Servicer would have been entitled to under this Agreement if no such resignation or termination had occurred, except that all collections on or in respect of the Receivables shall be deposited in the Collection Account within two (2) Business Days of receipt and shall not be retained by the successor Servicer. Notwithstanding the foregoing, the Indenture Trustee may, if it shall be unwilling so to act, or shall, if it is legally unable so to act, appoint, or petition a court of competent jurisdiction to appoint, an Eligible Servicer as the successor to the terminated Servicer under this Agreement. In connection with such appointment, the Indenture Trustee may make such arrangements for the compensation of such successor Servicer out of collections on or in respect of the Receivables as it and such successor shall agree; provided, however, that such compensation shall not be greater than that payable to CarMax as Servicer hereunder without the prior consent of the Holders of Notes evidencing at least 51% of the Note Balance of the Controlling Class. The Indenture Trustee and such successor Servicer shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. The Indenture Trustee shall not be relieved of its duties as successor Servicer under this Section 8.2 until a newly appointed Servicer shall have assumed the obligations and duties of the terminated Servicer under this Agreement. Notwithstanding anything to the contrary contained herein, in no event shall the Indenture Trustee be liable for any servicing fee or for any differential in the amount of the servicing fee paid hereunder and the amount necessary to induce any successor Servicer to act as successor Servicer hereunder.

(b) The successor Servicer is authorized and empowered to execute and deliver, on behalf of the outgoing Servicer, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the transfer of servicing to the successor Servicer, whether to complete the transfer and endorsement of the Receivable Files or the certificates of title to the Financed Vehicles or otherwise. The outgoing Servicer shall cooperate with the Indenture Trustee, the Owner Trustee and such successor Servicer in effecting the termination of its responsibilities and rights as Servicer under this Agreement, including the transfer to the successor Servicer for administration of all cash amounts that are at the time held by the outgoing Servicer for deposit or thereafter shall be received with respect to a Receivable, all Receivable Files and all information or documents that the successor Servicer may require. In addition, the outgoing Servicer shall transfer its electronic records relating to the Receivables to the successor Servicer in such electronic form as the successor Servicer may reasonably request. In no event shall the successor Servicer be liable if it cannot perform its duties hereunder because the outgoing

Servicer has breached the foregoing obligation to deliver such information or documents that the successor Servicer may require. All reasonable costs and expenses (including reasonable attorneys’ fees) incurred or payable by the successor Servicer in connection with the transfer of servicing (whether due to termination, resignation or otherwise), including allowable compensation of employees and overhead costs incurred or payable in connection with the transfer of the Receivable Files or any amendment to this Agreement required in connection with the transfer of servicing (the “Transition Costs”), shall be paid by any applicable then outgoing Servicer upon presentation of reasonable documentation of such costs and expenses. Any such Transition Costs not paid by the outgoing Servicer shall be paid solely from the application of Available Funds pursuant to Sections 2.8(a)(ii) and (xiii) or Section 5.4(b)(ii) of the Indenture, as applicable.

(c) Notwithstanding anything contained in this Agreement to the contrary, the successor Servicer is authorized to accept and rely on all of the accounting records (including computer records) and work of the prior Servicer relating to the Receivables (collectively, the “Predecessor Servicer Work Product”) without any audit or other examination thereof, and the successor Servicer shall have no duty, responsibility, obligation or liability for the acts and omissions of the prior Servicer. If any error, inaccuracy, omission or incorrect or non-standard practice or procedure (collectively, “Errors”) exists in any Predecessor Servicer Work Product and such Error makes it materially more difficult to service or should cause or materially contribute to the successor Servicer making or continuing any Error (collectively, “Continuing Errors”), the successor Servicer shall have no duty, responsibility, obligation or liability for such Continuing Errors; provided, however, that the successor Servicer agrees to use its best efforts to prevent further Continuing Errors. If the successor Servicer becomes aware of Errors or Continuing Errors, it shall, with the prior consent of the Holders of Notes evidencing at least 51% of the Note Balance of the Controlling Class, use its best efforts to reconstruct and reconcile such data as is commercially reasonable to correct such Errors and Continuing Errors and to prevent future Continuing Errors. The successor Servicer shall be entitled to recover its costs expended in connection with such efforts in accordance with Sections 2.8(a)(ii) and (xiii) of the Indenture, as applicable.

8.3 Effect of Servicing Transfer.

(a) After a transfer of servicing hereunder, the successor Servicer shall notify the Obligors to make directly to the successor Servicer payments that are due under the Receivables after the effective date of such transfer.

(b) Except as provided in Section 8.2, after a transfer of servicing hereunder, the outgoing Servicer shall have no further obligations with respect to the administration, servicing, custody or collection of the Receivables and the successor Servicer shall have all of such obligations, except that the outgoing Servicer will transmit or cause to be transmitted directly to the successor Servicer for its own account, promptly on receipt and in the same form in which received, any amounts or items held by the outgoing Servicer (properly endorsed where required for the successor Servicer to collect any such items) received as payments upon or otherwise in connection with the Receivables.

(c) Any successor Servicer shall provide the Depositor with access to the Receivable Files and to the successor Servicer’s records (whether written or automated) with respect to the Receivable Files. Such access shall be afforded without charge, but only upon reasonable request and during normal business hours at the offices of the successor Servicer. Nothing in this Section 8.3 shall affect the obligation of the successor Servicer to observe any applicable law prohibiting disclosure of information regarding the Obligors, and the failure of the Servicer to provide access to information as a result of such obligation shall not constitute a breach of this Section 8.3.

(d) Any transfer of servicing hereunder shall not constitute an assumption by the related successor Servicer of any liability of the related outgoing Servicer arising out of any breach by such outgoing Servicer of such outgoing Servicer’s duties hereunder prior to such transfer of servicing.

8.4 Notification to Noteholders, Certificateholders and Rating Agencies. Upon any notice of an Event of Servicing Termination or upon any termination of, or any appointment of a successor to, the Servicer pursuant to this Article VIII, the Indenture Trustee shall give prompt written notice thereof to the Noteholders and the Owner Trustee shall give prompt written notice thereof to the Certificateholders, the Administrator and the Depositor (who shall promptly give such notice to the Rating Agencies).

8.5 Waiver of Past Events of Servicing Termination. The Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class may, on behalf of all Noteholders, waive any Event of Servicing Termination and its consequences, except an event resulting from the failure to make any required deposits to or payments from the Collection Account, the Note Payment Account, the Certificate Payment Account or the Reserve Account in accordance with this Agreement. Upon any such waiver of an Event of Servicing Termination, such event shall cease to exist, and shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other event or impair any right arising therefrom, except to the extent expressly so waived.

8.6 Repayment of Advances. If the identity of the Servicer shall change, the predecessor Servicer shall be entitled to receive reimbursement for outstanding and unreimbursed Simple Interest Advances made pursuant to Section 4.4 by the predecessor Servicer.
