CarMax Auto Funding LLC, a Delaware limited liability company (the “Depositor”), confirms its agreement with Barclays Capital Inc., as representative (the “Representative”) of the several underwriters named in Schedule A hereto (together with any underwriter substituted as hereinafter provided in Section 11, the “Underwriters”), with respect to the sale by the Depositor to the Underwriters, and the purchase by the Underwriters, acting severally and not jointly, of $114,000,000 aggregate principal amount of 0.40716% Class A-1 Asset Backed Notes (the “Class A-1 Notes”), $216,000,000 aggregate principal amount of 0.70% Class A-2 Asset Backed Notes (the “Class A-2 Notes”), $198,000,000 aggregate principal amount of 1.07% Class A-3 Asset Backed Notes (the “Class A-3 Notes”), $85,600,000 aggregate principal amount of 1.51% Class A-4 Asset Backed Notes (the “Class A-4 Notes”), $13,650,000 aggregate principal amount of 2.17% Class B Asset Backed Notes (the “Class B Notes”), $11,700,000 aggregate principal amount of 2.76% Class C Asset Backed Notes (the “Class C Notes”) and $11,050,000 aggregate principal amount of 3.90% Class D Asset Backed Notes (the “Class D Notes” and, together with the Class A-1 Notes, the Class A-2 Notes, the Class A-3 Notes, the Class A-4 Notes, the Class B Notes and the Class C Notes, the “Notes”) of CarMax Auto Owner Trust 2011-3 (the “Trust”) under the terms and conditions contained herein. The Notes will be issued pursuant to an indenture, dated as of November 1, 2011 (the “Indenture”), between the Trust and Xxxxx Fargo Bank, National Association, as trustee (the “Indenture Trustee”).

The Depositor understands that the Underwriters propose to make a public offering of the Notes as soon as the Representative deems advisable after this Agreement has been executed and delivered and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

Simultaneously with the issuance and sale of the Notes as contemplated herein, the Trust will issue the CarMax Auto Owner Trust 2011-3 Asset Backed Certificates (the “Certificates” and, together with the Notes, the “Securities”). The Trust was created and the Certificates will be issued pursuant to an amended and restated trust agreement, dated as of November 1, 2011 (the “Trust Agreement”), among the Depositor, The Bank of New York Mellon (“BONY”), as trustee (the “Owner Trustee”), and BNY Mellon Trust of Delaware (“BONY Delaware”), as Delaware trustee (the “Delaware Trustee”). Each Note will represent an obligation of the Trust, each Certificate will represent an undivided beneficial interest in the Trust and the Certificates will be subordinated to the Notes to the extent described in the Indenture and the Trust Agreement.

The assets of the Trust will include, among other things, (i) a pool of motor vehicle retail installment sale contracts (the “Receivables”) secured by the new and used motor vehicles financed thereby (the “Financed Vehicles”), (ii) certain monies payable under the Receivables after October 31, 2011, (iii) security interests in the Financed Vehicles, (iv) amounts on deposit in certain accounts, (v) certain rights under a receivables purchase agreement, dated as of November 1, 2011 (the “Receivables Purchase Agreement”), between CarMax Business Services, LLC (“CarMax LLC”) and the Depositor, pursuant to which CarMax LLC will sell the Receivables to the Depositor, (vi) certain rights under a sale and servicing agreement, dated as of November 1, 2011 (the “Sale and Servicing Agreement”), among the Trust, the Depositor, CarMax LLC, as servicer (in such capacity, the “Servicer”), and Xxxxx Fargo Bank, National Association, as backup servicer, pursuant to which the Receivables and other property of the Trust will be sold to the Trust and the Receivables will be serviced by the Servicer and (vii) and all proceeds of the foregoing. Pursuant to the Indenture, the Trust Estate will be held by the Indenture Trustee on behalf of the holders of the Notes. Pursuant to an administration agreement, dated as of November 1, 2011 (the “Administration Agreement”), among CarMax LLC, as administrator (in such capacity, the “Administrator”), the Trust and the Indenture Trustee, the Administrator will perform certain administrative obligations of the Trust under the Indenture. The Indenture, the Trust Agreement, the Administration Agreement, the Sale and Servicing Agreement and the Receivables Purchase Agreement are referred to herein collectively as the “Basic Documents”. Capitalized terms used herein that are not otherwise defined shall have the meanings ascribed thereto in the Indenture or the Sale and Servicing Agreement, as the case may be.

The Depositor has prepared and filed with the Securities and Exchange Commission (the “Commission”), a registration statement on Form S-3 (File No. 333-174975), including a base prospectus and a form of preliminary prospectus supplement relating to the offering of asset backed notes and asset backed certificates, issued in series from time to time in accordance with Rule 415 (“Rule 415”) of the rules and regulations of the Commission (the “Securities Act

Regulations”) under the Securities Act of 1933, as amended (the “Securities Act”). Such registration statement covers the registration of the Notes under the Securities Act and has been declared effective by the Commission.

Promptly after execution and delivery of this Agreement, the Depositor will prepare and file with the Commission a final base prospectus and a final prospectus supplement relating to the Notes in accordance with the provisions of Rule 430B of the Securities Act Regulations (“Rule 430B”) and paragraph (b) of Rule 424 of the Securities Act Regulations (“Rule 424(b)”). Any information included in such base prospectus and prospectus supplement that was omitted from the registration statement at the time it became effective but that is deemed to be part of and included in such registration statement pursuant to Rule 430B is referred to as “Rule 430B Information”. Such registration statement, at any given time, including the amendments thereto to such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference pursuant to the Securities Act at such time and documents otherwise deemed to be a part thereof or included therein by the Securities Act Regulations, is herein called the “Registration Statement”.

“Base Prospectus” means the base prospectus included in the Registration Statement, as amended at the time of the filing of the Preliminary Prospectus. “Preliminary Prospectus” means the Base Prospectus and the Preliminary Prospectus Supplement (including the information referred to under the caption “CarMax—Static Pool Information About Previous Securitizations” therein regardless of whether such information is deemed a part of the Registration Statement or Prospectus), used in connection with the offering of the Notes that omitted the Rule 430B Information and is used prior to the filing of the Prospectus, including the documents incorporated by reference therein pursuant to the Securities Act at the Time of Sale. “Prospectus” means the Prospectus Supplement (including the information referred to under the caption “CarMax—Static Pool Information About Previous Securitizations” therein regardless of whether such information is deemed a part of the Registration Statement or Prospectus) to the Base Prospectus that is first filed after the Time of Sale pursuant to Rule 424(b), together with the Base Prospectus, as amended at the time of such filing, including the documents incorporated by reference therein pursuant to the Securities Act at the Time of Sale or at the Closing Time, as applicable. “Prospectus Supplement” means the prospectus supplement to the Base Prospectus included in the Prospectus. “Preliminary Prospectus Supplement” means the preliminary prospectus supplement, dated October 27, 2011, included in the Preliminary Prospectus.

“Issuer Free Writing Prospectus” means any “issuer free writing prospectus”, as defined in Rule 433 of the Securities Act Regulations (“Rule 433”), relating to the Notes that (i) is required to be filed with the Commission by the Depositor, (ii) is a “road show that is a written communication” within the meaning of Rule 433(d)(8)(i), whether or not required to be filed with the Commission, (iii) is exempt from filing pursuant to Rule 433(d)(5)(i) because it contains a description of the Notes or of the offering that does not reflect the final terms and (iv) the free writing prospectus dated October 27, 2011 (the “Ratings Free Writing Prospectus”), in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Depositor’s records pursuant to Rule 433(g).

“Issuer General Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, and is specified in Schedule B hereto. “Issuer Limited Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is not an Issuer General Use Free Writing Prospectus.

At or prior to the time when sales to purchasers of the Notes were first made by the Underwriters, which was approximately 2:16 p.m., New York City time, on November 2, 2011 (the “Time of Sale”), the Depositor had prepared (i) the Issuer General Use Free Writing Prospectus(es) issued at or prior to the Time of Sale and (ii) the Preliminary Prospectus, dated October 27, 2011 and (iii) the information contained on Schedule C hereto (collectively, the “Time of Sale Information”). If, at or subsequent to the Time of Sale and prior to the Closing Time, such information included an untrue statement of material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, and as a result investors in the Notes may terminate their old “Contracts of Sale” (as that term is used in Rule 159 under the Securities Act) for any Notes and the Underwriters enter into new Contracts of Sale with investors in the Notes, then “Time of Sale Information” will refer to the information conveyed to investors at the time of entry into the first such new Contract of Sale in connection with an amended Preliminary Prospectus approved by the Depositor and the Representative that corrects such material misstatements or omissions (a “Corrected Prospectus”) and “Time of Sale” will refer to the time and date on which such new Contracts of Sale were entered into.

All references in this Agreement to financial statements and schedules and other information which is “contained”, “included” or “stated” in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Prospectus or any Corrected Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which are or are deemed to be incorporated by reference in or otherwise deemed by the Securities Act Regulations to be a part of or included in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Prospectus or any Corrected Prospectus, as the case may be. All references in this Agreement to the terms “amend”, “amendments” or “supplements” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Prospectus or any Corrected Prospectus shall be deemed to mean and include the filing of any documents under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), after the effective date (the “Effective Date”) of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus, the Prospectus or any Corrected Prospectus, as the case may be, which are or are deemed to be incorporated by reference therein or otherwise deemed by the Securities Act Regulations to be a part thereof or included therein. For purposes of this Agreement, all references to the Registration Statement, any Preliminary Prospectus, the Prospectus, the Corrected Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis, and Retrieval system (“XXXXX”).

Section 1. Representations and Warranties.

(a) Representations and Warranties by the Depositor. The Depositor represents and warrants to the Underwriters as of the date hereof, the Time of Sale and as of the Closing Time referred to in Section 2(b) and agrees with the Underwriters as follows:

(i) Compliance with Registration Requirements. The Depositor meets the requirements for use of Form S-3 under the Securities Act. The Registration Statement, at the Time of Sale, meets the requirements set forth in Rule 415(a)(1)(x). At the time the Registration Statement was originally filed, at the earliest time thereafter that the Depositor or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the Securities Act Regulations) of the Notes and at the date hereof and at the date the Depositor delivers or causes to be delivered each Issuer General Use Free Writing Prospectus, the Depositor was not, is not and will not be an “ineligible issuer”, as defined in Rule 405 of the Securities Act Regulations.

(ii) Registration Statement, Prospectus and Disclosure at Time of Sale.

(A) The Registration Statement became effective on July 8, 2011, and any post-effective amendment thereto also has become effective. The Registration Statement is effective and no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Depositor, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with. The Indenture has been duly qualified under the Trust Indenture Act.

(B) At the respective times the Registration Statement and each amendment thereto became effective, at each deemed effective date with respect to the Underwriters pursuant to Rule 430B(f) and at the Closing Time, the Registration Statement complied and will comply in all material respects with the requirements of the Securities Act, the Securities Act Regulations, the Trust Indenture Act and the rules and regulations of the Commission under the Trust Indenture Act (the “Trust Indenture Act Regulations”) and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(C) When filed with the Commission, each Preliminary Prospectus (including the prospectus and prospectus supplement filed as part of the Registration Statement or any amendment thereto) complied when so filed in all material respects with the Securities Act Regulations, and each Preliminary Prospectus and the Prospectus delivered to the Underwriters for use in connection with the offering of the Notes will, at the time of such delivery, be identical to any electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

(D) When filed with the Commission, the Prospectus shall include all information with respect to the offering of the Notes required by the Securities Act, the Trust Indenture Act, the Securities Act Regulations and the Trust Indenture Act Regulations and shall be in all substantive respects in the form furnished to the Representative prior to the Time of Sale or, to the extent not

completed at the Time of Sale, shall contain only such specific additional information and other changes (beyond those contained in the latest preliminary base prospectus and preliminary prospectus supplement, if any, that have been previously furnished to the Representative) as the Depositor has advised the Representative, prior to the Time of Sale, will be included or made therein.

(E) The Preliminary Prospectus, at the date thereof, did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, that no representation or warranty is made with respect to the omission of information in the Preliminary Prospectus regarding the amount of the Notes or pricing and price-dependent information.

(F) Neither the Prospectus nor any amendment or supplement thereto, at the time the Prospectus or any such amendment or supplement was issued and at the Closing Time, included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(G) As of the Time of Sale and the Closing Time neither (1) the Time of Sale Information nor (2) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the Time of Sale Information, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(H) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Notes or until any earlier date that the Depositor notified or notifies the Representative as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein and any Preliminary Prospectus or other prospectus deemed to be a part thereof that has not been superseded or modified.

(I) If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Depositor will promptly notify the Representative and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or the Time of Sale Information made in reliance upon and in conformity with the Underwriters’ Information (as defined in Section 7(a)).

(iii) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission thereunder (the “Exchange Act Regulations”) and, when read together with the other information in the Prospectus, at the Effective Date, at the Time of Sale and at the Closing Time, did not and will not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

Since the respective dates as of which information is given in the Registration Statement, the Time of Sale Information and the Prospectus, except as otherwise set forth therein, (A) there has been no Material Adverse Effect with respect to the Depositor and (B) there have been no transactions entered into by the Depositor, other than those in the ordinary course of business, which are material with respect to it. As used herein, the term “Material Adverse Effect” means, when used with respect to either the Depositor or CarMax LLC, as the case may be, a material adverse change in its condition, financial or otherwise, or in its earnings, business affairs or business prospects, whether or not arising in the ordinary course of business, or in its ability to perform its obligations under this Agreement and each Basic Document to which it is a party.

(v) Due Organization. The Depositor has been duly formed and is validly existing as a limited liability company under the laws of the State of Delaware, and all filings required at the date hereof under the Delaware Limited Liability Company Act (6 Del. C. §18-101, et seq.) (the “LLC Act”) with respect to the due formation and valid existence of the Depositor as a limited liability company have been made; the Depositor has all requisite power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement and the Prospectus and to enter into and to perform its obligations under each Basic Document to which it is a party (collectively, the “Depositor Agreements”), this Agreement and the Securities; and the Depositor is duly qualified or registered as a foreign limited liability company to transact business and is in good standing in each jurisdiction in which such qualification or registration is required, whether by reason of the ownership of property or the conduct of business, except where the failure to so qualify or register or to be in good standing would not result in a Material Adverse Effect.

(vi) Authorization of this Agreement. This Agreement has been duly authorized, executed and delivered by the Depositor.

(vii) Authorization of Basic Documents. As of the Closing Time, each Depositor Agreement has been duly authorized, executed and delivered by the Depositor, and, assuming the due authorization, execution and delivery thereof by the other parties thereto, will constitute a valid and binding agreement of the Depositor, enforceable against it in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally and except as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).

(viii) Issuance of the Notes. The Notes have been duly authorized and, at the Closing Time, will have been duly executed and, when authenticated, issued and delivered in the manner provided for in the Indenture and delivered against payment of the purchase price therefor as provided in this Agreement, will constitute valid and binding obligations of the Trust, enforceable against the Trust in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally and except as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law), and will be in the form contemplated by, and entitled to the benefits of, the Indenture.

(ix) Issuance of the Certificates. The Certificates have been duly authorized and, at the Closing Time, will have been duly executed and, when authenticated, issued and delivered in the manner provided for in the Trust Agreement, will be validly issued, fully paid, non-assessable and outstanding and will be in the form contemplated by, and entitled to the benefits of, the Trust Agreement.

(x) Description of the Securities and Basic Documents. The Securities and the Basic Documents conform in all material respects to the descriptions thereof and the statements relating thereto contained in the Registration Statement and the Prospectus.

(xi) Absence of Defaults and Conflicts. The Depositor is not in violation of its limited liability company agreement or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which it is a party or by which it may be bound, or to which any of its properties, operations or assets is subject (collectively, the “Depositor Agreements and Instruments”), except for violations or defaults that, individually or in the aggregate, would not result in a Material Adverse Effect with respect to the Depositor; and the execution, delivery and performance by the Depositor of the Depositor Agreements, this Agreement and the Securities, the consummation of the transactions contemplated herein or therein, in the Registration Statement or in the Prospectus (including the sale of the Notes to the Underwriters pursuant to the terms of this Agreement and the use of proceeds therefrom as described under the heading “Use of Proceeds” in the Prospectus) and compliance by it with its obligations hereunder and thereunder have been duly and validly authorized by all necessary action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a

breach of, a default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, mortgage, pledge, charge, encumbrance, adverse claim or other security interest (collectively, “Liens”) upon any of its property or assets pursuant to the Depositor Agreements and Instruments except for Liens permitted by the Basic Documents and conflicts, breaches or defaults that, individually or in the aggregate, will not result in a Material Adverse Effect with respect to the Depositor, nor will such action result in any violation of the provisions of its limited liability company agreement or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Depositor or any of its assets, properties or operations. As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Depositor or CarMax LLC, as the case may be.

(xii) Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending or, to the knowledge of the Depositor, threatened, against or affecting the Depositor which is required to be disclosed in the Registration Statement and the Prospectus (other than as stated therein or stated in a document incorporated by reference therein), or which might reasonably be expected to result in a Material Adverse Effect with respect to the Depositor; the aggregate of all pending legal or governmental proceedings to which the Depositor is a party or of which any of its properties or assets is the subject which are not described in the Registration Statement and the Prospectus, including ordinary routine litigation incidental to the business, could not reasonably be expected to result in a Material Adverse Effect with respect to the Depositor.

(xiii) Accuracy of Exhibits. There are no contracts or documents which are required to be described in the Registration Statement, the Prospectus or the documents incorporated by reference therein which have not been so described and filed as required.

(xiv) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court, governmental authority or agency or any other person is necessary in connection with (A) the issuance of the Securities or the offering and sale of the Notes, (B) the authorization, execution, delivery and performance by the Depositor of the Depositor Agreements or this Agreement or (C) the consummation by the Depositor of the transactions contemplated hereby or thereby, except such as have been obtained and are in full force and effect as of the Closing Time.

(xv) Possession of Licenses and Permits. The Depositor possesses or, as of the Closing Time, has applied for, such permits, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct the business now operated by it; the Depositor is in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, have a Material Adverse Effect with respect to the Depositor; except for

Governmental Licenses that have been applied for as of the Closing Time, all of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not have a Material Adverse Effect with respect to the Depositor or would not render a material portion of the Receivables unenforceable; and the Depositor has not received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Material Adverse Effect with respect to the Depositor or would render a material portion of the Receivables unenforceable.

(xvi) Title to Receivables; Payment of Fees. As of the Closing Time, the (A) Depositor will have good and marketable title to the Receivables listed in Schedule 1 to the Sale and Servicing Agreement, free and clear of any Lien, (B) Depositor’s assignment and delivery of the Receivables to the Trust will vest in the Trust the good and marketable title purported to be conveyed thereby to, (C) Trust will be the sole owner of each Receivable free and clear of Liens other than the Lien in favor of the Indenture Trustee under the Indenture and (D) Trust’s Grant of the Collateral to the Indenture Trustee pursuant to the Indenture will vest in the Indenture Trustee, for the benefit of the Noteholders, a first priority perfected security interest therein, subject to no prior Lien; and all taxes, fees and other governmental charges arising in connection with the transactions contemplated by this Agreement and the Basic Documents and with the execution and delivery of the Receivables, including any amendments thereto and assignments and/or endorsements thereof, have been paid by the Depositor.

(xvii) Investment Company Act. Neither the Trust nor the Depositor is, or after giving effect to the sale of the Notes and the use of proceeds thereof will be, required to be registered as an “investment company” under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

(xviii) Incorporation of Representations and Warranties. The representations and warranties of the Depositor in each Depositor Agreement are true and correct in all material respects and are hereby incorporated by reference herein and restated for the benefit of the Underwriters with the same effect as if set forth in full herein.

(b) Representations and Warranties by CarMax LLC. CarMax LLC represents and warrants to the Underwriters as of the date hereof and as of the Closing Time that the representations and warranties of the Depositor set forth in Section 1(a) are true and correct as of the time made and further represents and warrants to and agrees with the Underwriters as follows:

CarMax LLC has been duly formed and is validly existing as a limited liability company under the laws of the State of Delaware, and all filings required at the date hereof under the LLC Act with respect to the due formation and valid existence of CarMax LLC as a limited liability company have been made; CarMax LLC is duly qualified or registered as a foreign limited liability company to transact business, and is in good standing, in each jurisdiction where the character of its

properties or the nature of its activities makes such qualification necessary, except such jurisdictions, if any, in which the failure to be so qualified will not have a material adverse effect on either the business or properties of CarMax LLC or on the ability of CarMax LLC to perform its obligations under each Basic Document to which it is a party (collectively, the “CarMax Agreements”) and this Agreement; CarMax LLC has the requisite power and authority to own its properties and conduct its business as described in the Prospectus and to enter into and perform its obligations under each CarMax Agreement; and CarMax LLC holds all material licenses, certificates and permits from all governmental authorities necessary for the conduct of its business as described in the Prospectus.

(ii) Authorization of this Agreement. This Agreement has been duly authorized, executed and delivered by CarMax LLC.

(iii) Authorization of Basic Documents. As of the Closing Time, each CarMax Agreement has been duly authorized, executed and delivered by CarMax LLC, and, assuming the due authorization, execution and delivery thereof by the other parties thereto, will constitute a valid and binding agreement of CarMax LLC, enforceable against it in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally and except as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).

(iv) Absence of Defaults and Conflicts. CarMax LLC is not in violation of its limited liability company agreement or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which it is a party or by which it may be bound, or to which any of its properties, operations or assets is subject (collectively, the “CarMax Agreements and Instruments”), except for violations or defaults that, individually or in the aggregate, would not result in a Material Adverse Effect with respect to CarMax LLC; and the execution, delivery and performance by CarMax LLC of the CarMax Agreements and this Agreement, the consummation of the transactions contemplated herein or therein, in the Registration Statement or in the Prospectus and compliance by it with its obligations hereunder and thereunder have been duly and validly authorized by all necessary action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, a default or Repayment Event under, or result in the creation or imposition of any Lien upon any of its property or assets pursuant to the CarMax Agreements and Instruments except for Liens permitted by the Basic Documents and conflicts, breaches or defaults that, individually or in the aggregate, will not result in a Material Adverse Effect with respect to CarMax LLC, nor will such action result in any violation of the provisions of its articles of incorporation or bylaws or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over CarMax LLC or any of its assets, properties or operations.

(v) Absence of Proceedings.

(c) Officer’s Certificates. Any certificate signed by any officer of CarMax LLC, the Depositor or any of their respective Affiliates and delivered at the Closing Time to the Representative or to counsel for the Underwriters shall be deemed a representation and warranty by CarMax LLC, the Depositor or such Affiliate, as the case may be, to the Underwriters as to the matters covered thereby.

(a) Compliance with Securities Act Regulations and Commission Requests. The Depositor, subject to Section 3(b), will comply with the requirements of Rules 424(b) and 430B and will notify the Representative immediately, and confirm the notice in writing, of (i) the effectiveness of any post-effective amendment to the Registration Statement or the filing of any supplement or amendment to the Prospectus, (ii) the receipt of any comments from the Commission, (iii) any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or any document incorporated by reference therein or otherwise deemed to be a part thereof or for additional information, (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any Preliminary Prospectus, or of the suspension of the qualification of the Notes for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes and (v) the happening of any event during the period referred to in Section 3(d) which, in the judgment of the Depositor, makes the Registration Statement or the Prospectus contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing at the time it is delivered or made available to a purchaser, not misleading. The Depositor will effect the filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), and will take such steps as it deems necessary to ascertain promptly whether the Prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file the Prospectus. The Depositor will effect any required filing of each Issuer Free Writing Prospectus pursuant to Rule 433 in the manner and within the time period required by Rule 433(d). The Depositor will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. The Depositor will give the Representative notice of its intention to file or prepare any amendment to the Registration Statement or any amendment, supplement or revision to either any preliminary prospectus (including any prospectus included in the Registration Statement or amendment thereto at the time it became effective) or to the Prospectus, whether pursuant to the Securities Act, the Exchange Act or otherwise, and the Depositor will furnish the Representative with copies of all such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representative or counsel for the Underwriters shall object.

(c) Delivery of Registration Statements. The Depositor has furnished or will deliver to the Representative and counsel for the Underwriters, without charge, a signed copy of the Registration Statement and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein or otherwise deemed to be a part thereof) and a signed copy of all consents and certificates of experts, and will also deliver to the Representative, without charge, a conformed copy of the Registration Statement and of each amendment thereto (without exhibits) for each of the Underwriters. The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

(d) Delivery of Offering Documents. The Depositor will deliver to each Underwriter, without charge, as many copies of each Preliminary Prospectus as such Underwriter may reasonably request, and the Depositor hereby consents to the use of such copies for purposes permitted by the Securities Act. The Depositor will furnish to each Underwriter, without charge, during the period when a prospectus is required to be delivered under the Securities Act or the Exchange Act, such number of copies of the Prospectus as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. The Depositor will comply with the Securities Act and the Securities Act Regulations, the Exchange Act and the Exchange Act Regulations and the Trust Indenture Act Regulations so as to permit the completion of the distribution of the Notes as contemplated in this Agreement, the Basic Documents, the Registration Statement and the Prospectus. If at any time when a prospectus is required by the Securities Act to be delivered in connection with sales of the Notes, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or counsel to the Depositor, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the Securities Act or the Securities Act Regulations, the Depositor will promptly prepare and file with the Commission, subject to the review and approval provisions afforded to the Representative described in Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, the Depositor will use its best efforts to have such amendment declared effective as soon as practicable and the Depositor will furnish to the Underwriters, without charge, such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light

of the circumstances prevailing at that subsequent time, not misleading, the Depositor will promptly notify the Representative and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(f) State Securities Law Qualifications. The Depositor will use its best efforts, in cooperation with the Underwriters, in arranging for the registration and qualification of the Notes for offering and sale and the determination of their eligibility for investment, as the case may be, under the laws of such jurisdictions as the Underwriters designate and will continue to assist the Underwriters in maintaining such registrations and qualifications in effect for a period of not less than one year from the date of the Prospectus and in filing such consents to service of process or other documents as may be necessary in order to effect such registrations and qualifications; provided, however, that the Depositor shall not be obligated to file any general consent to service of process or to qualify as a foreign limited liability company or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. The Depositor will also supply the Underwriters with such information as is necessary for the determination of the legality of the offering and sale of the Notes for investment under the laws of such jurisdictions as the Underwriters may reasonably request.

(g) Earnings Statement. The Depositor will timely file such reports pursuant to the Exchange Act as are necessary in order to cause the Trust to make generally available to holders of the Notes as soon as practicable an earnings statement for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the Securities Act and Rule 158 under the Securities Act.

(h) Use of Proceeds. The Depositor shall cause the Trust to use the net proceeds received by it from the sale of the Notes in the manner specified in the Base Prospectus under “Use of Proceeds”.

(i) Reports, Statements and Certificates. So long as any Notes are outstanding, the Depositor shall deliver or cause to be delivered to the Underwriters, as soon as copies become available, copies of (i) each payment date certificate delivered to Securityholders pursuant to Section 4.9 of the Sale and Servicing Agreement, (ii) the annual statements of compliance, annual independent certified public accountants’ reports and annual opinions of counsel furnished to the Indenture Trustee or the Owner Trustee pursuant to the Basic Documents, as soon as such statements, reports and opinions are furnished to the Indenture Trustee or the Owner Trustee, as the case may be, (iii) all documents of the Depositor or the Trust required to be filed with the Commission pursuant to the Exchange Act or any order of the Commission thereunder and (iv) such other information concerning CarMax LLC, the Depositor, the Trust or the Securities as the Underwriters may reasonably request from time to time.

(j) Reporting Requirements. The Depositor, during the period when the Prospectus is required to be delivered under the Securities Act or the Exchange Act, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and the Exchange Act Regulations.

(b) Termination of Agreement.

(v) The authorization, execution, delivery and performance by CarMax LLC of this Agreement and the CarMax Agreements and the Depositor of this Agreement and the Depositor Agreements and the consummation of the transactions contemplated hereby and thereby, including the issuance and delivery of the Securities and the offering and sale of the Notes do not require the consent, authorization, license, order, registration, qualification, decree or approval of, or any filing with, any court or governmental agency or body having jurisdiction over CarMax LLC or the Depositor (except such consents, authorizations, approvals or filings as have been obtained or made and as are in full force and effect as of the Closing Time or those that may be required under the state securities or blue sky laws of the various states, and except for the filing of UCC-3 partial release statements relating to the release of the existing liens on the Receivables and the other property of the Trust of CarMax LLC’s secured lenders and the filing of UCC-1 financing statements relating to the conveyance of the Receivables and other property of the Trust by the Depositor to the Trust and by the Trust to the Indenture Trustee, which Uniform Commercial Code (“UCC”) financing statement filings are in the process of being made) and do not (A) result in the creation or imposition of any Lien upon any property or assets of CarMax LLC or the Depositor pursuant to the terms of any CarMax Agreement and Instrument or any Depositor Agreement and Instrument, as the case may be, (except for (1) Liens permitted by the Basic Documents and (2) such conflicts, breaches or defaults or liens, charges or encumbrances that would not have a Material Adverse Effect on CarMax LLC or the Depositor, as the case may be) and (B) conflict with, violate, result in a breach of or constitute a default under (1) any term or provision of the certificate of formation or limited liability company agreement of CarMax LLC or any term or provision of the limited liability company agreement of the Depositor, (2) in any material respect, any law, statute, order known to such counsel, rule or regulation of any court or governmental agency or body having jurisdiction over CarMax LLC or the Depositor or (3) any CarMax Agreement and Instrument or any Depositor Agreement and Instrument known to such counsel.

(ix) To the best knowledge of such counsel, no default by the Depositor exists in the due performance or observance of any obligation, agreement, covenant or condition contained in the Depositor Agreements and Instruments, except for defaults that would not result in a Material Adverse Effect with respect to the Depositor.

Such counsel shall also state that such counsel has examined the Registration Statement, the Preliminary Prospectus and the Prospectus and nothing has come to such counsel’s attention that would lead such counsel to believe that: (i) the Registration Statement, at the time it originally became effective, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) the Registration Statement, including the Rule 430B Information, at each deemed effective date with respect to the

Underwriters pursuant to Rule 430B(f)(2), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; or (iii) the Prospectus at the date thereof and at the Closing Time, included or includes any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that in each of clauses (i), (ii) and (iii) such counsel need make no statement with respect to any financial statements and schedules and other financial, numerical, statistical and quantitative information, in each case contained or incorporated by reference therein or omitted therefrom and the Form T-1.

With respect to statements contained in the Time of Sale Information, any statement contained in any of the constituent documents shall be deemed modified or superseded to the extent any information contained in subsequent constituent documents modifies or replaces such statement. In connection with such counsel’s statements in clause (ii) above, such counsel may assume that the Ratings Free Writing Prospectus is conveyed to all initial and subsequent purchasers of the Notes prior to their entry into a contract of sale for the Notes.

In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental

agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section or Section 8 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

Section 8. Contribution. If the indemnification provided for in Section 7 is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by CarMax LLC and the Depositor on the one hand and the Underwriters on the other hand from the offering of the Notes pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of CarMax LLC and the Depositor on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by CarMax LLC and the Depositor on the one hand and the Underwriters on the other hand in connection with the offering of the Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes pursuant to this Agreement (before deducting expenses) received by CarMax LLC and the Depositor and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate initial public offering prices of the Notes. The relative fault of CarMax LLC and the Depositor on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by CarMax LLC or the Depositor or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

CarMax LLC, the Depositor and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations

referred to above in this Section. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever, based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section, no Underwriter shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter in respect of the Notes underwritten by it and distributed to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. The Underwriters’ respective obligations to contribute pursuant to this Section are (i) several and not joint and (ii) subject to the preceding sentence, in proportion to the principal amount of Notes set forth opposite their respective names in Schedule A.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each person, if any, who controls CarMax LLC or the Depositor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as CarMax LLC and the Depositor.

Section 9. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement (including, without limitation, Sections 7 and 8) or in certificates of officers of CarMax LLC, the Depositor and their respective Affiliates submitted pursuant hereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Underwriters or any controlling person, or by or on behalf of CarMax LLC, the Depositor and their respective Affiliates, and shall survive delivery of the Notes to the Underwriters.

Section 10. Termination of Agreement.

(a) Termination; General. The Underwriters may terminate this Agreement, by notice to the Depositor, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus or the Time of Sale Information, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of CarMax LLC or the Depositor, whether or not arising in the ordinary course of business, (ii) if there has occurred any material adverse change in the financial markets in the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of

the Representative, impracticable or inadvisable to market the Notes or to enforce contracts for the sale of the Notes, (iii) if trading in any securities of CarMax LLC, the Depositor or any of their respective Affiliates has been suspended or materially limited by the Commission or if trading generally on the American Stock Exchange, the New York Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, (iv) a material disruption has occurred in commercial banking or securities settlement or clearing services in the United States or (v) if a banking moratorium has been declared by either federal, Virginia, North Carolina or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4, and provided further that Sections 1, 7, 8, 9 and 14 shall survive such termination and remain in full force and effect.

Section 11. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time to purchase the Notes which it or they are obligated to purchase (the “Defaulted Notes”), then the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:

(i) if the aggregate principal amount of Defaulted Notes does not exceed 10% of the aggregate principal amount of Notes to be purchased on such date, the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations in Schedule A bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii) if the aggregate principal amount of Defaulted Notes exceeds 10% of the aggregate principal amount of Notes to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement either the Representative or the Depositor shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements.
