The Depositor has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement onForm SF-3 (FileNo. 333-228379), including a form of preliminary prospectus 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. Such registration statement, at any specified time (or, if no time is otherwise specified, at the Time of Sale, as defined below), including the amendments thereto at 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”.

Promptly after execution and delivery of this Agreement, the Depositor will prepare and file with the Commission a final prospectus relating to the Notes in accordance with the provisions of Rule 430D of the Securities Act Regulations (“Rule 430D”) and paragraph (b) of Rule 424 of the Securities Act Regulations (“Rule 424(b)”). Any information included in such prospectus 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 430D is referred to as “Rule 430D Information”.

“Preliminary Prospectus” means the Preliminary Prospectus dated January 9, 2019 (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 430D 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 dated January 16, 2019 (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) that is first filed after the Time of Sale pursuant to Rule 424(b), 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 defined in Section 2(b)), as applicable.

“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, including any Road Show as defined herein, (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 or (iv) is the free writing prospectus, dated January 9, 2019 (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 4:12 p.m., New York City time, on January 16, 2019 (the “Time of Sale”), the Depositor had prepared (i) the Issuer General Use Free Writing Prospectus(es) and (ii) the Preliminary Prospectus (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 Regulations) 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, 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, 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, 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 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 (“EDGAR”).

The Depositor will effect the filings required under Rule 424(h) and Rule 424(b), in the manner and within the time period required by Rule 424(h) and Rule 424(b) (without reliance on Rule 424(b)(8)), as applicable, and will take such steps as it deems necessary to ascertain promptly whether the Preliminary Prospectus and the Prospectus transmitted for filing under Rule 424(h) and Rule 424(b), as applicable, was received for filing by the Commission and, in the event that it was not, it will promptly file the Preliminary Prospectus and 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), the Preliminary Prospectus or 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 reasonably object.

(d)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, the Preliminary Prospectus and the Prospectus.

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.

Any expenses incurred in connection with maintaining any such qualification for more than one year from the date of the Prospectus will be at the Representative’s expense. 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.

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred: (A) arising out of any untrue statement or alleged untrue statement of a material fact (1) contained in the Registration Statement (or any amendment thereto), including the Rule 430D Information or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or (2) included in the Time of Sale Information, any Issuer Free Writing

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever, based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d)) any such settlement is effected with the written consent of CarMax LLC or the Depositor; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representative and reasonably approved by the Depositor), reasonably incurred 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 statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under clause (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Depositor by the Underwriters through the Representative expressly for use in the Registration Statement (or any amendment thereto), the Time of Sale Information, including the Rule 430D Information or any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information furnished to the Depositor by the Underwriters through the Representative consists of the following information under the caption “Underwriting” in the Prospectus: the (1) concession and reallowance figures appearing in the second table and (2) information in the fourth paragraph and the second sentence of the ninth paragraph (which paragraph immediately follows the second table) under such caption insofar as they relate to market-making transactions ((1) and (2), collectively, the “Underwriters’ Information”); provided, further, that this indemnity

with respect to the Time of Sale Information, any Issuer Free Writing Prospectus or any Issuer Information delivered prior to the Time of Sale shall not inure to the benefit of any Underwriter (or to the benefit of any person controlling the Underwriter) from whom the person asserting any such losses, liabilities, claims, damages or expenses purchased the Notes if such untrue statement or omission or alleged untrue statement or omission made in such information is eliminated as remedied in a Corrected Prospectus delivered to such Underwriter prior to the revised Time of Sale and a copy of the Corrected Prospectus shall not have been furnished to such person at or prior to the revised Time of Sale of such Notes to such person.

(b)Indemnification of CarMax LLC and the Depositor. Each Underwriter, severally but not jointly, agrees to indemnify and hold harmless CarMax LLC and the Depositor, each person, if any, who controls CarMax LLC and the Depositor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and the respective officers, directors, agents and employees of each of the foregoing against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 7(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, of material facts made in (i) the Registration Statement (or any amendment thereto), the Time of Sale Information, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Depositor by such Underwriter (including, if applicable, through the Representative) expressly for use therein, it being understood and agreed that the only such information furnished to the Depositor by the Underwriters (including, if applicable, through the Representative) consists of the Underwriters’ Information and (ii) any Underwriter Free Writing Prospectus that does not result from an error or omission in the Registration Statement, the Time of Sale Information, any Issuer Free Writing Prospectus, any Issuer Information or the Prospectus (other than any Underwriters’ Information).

(c)Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 7(a), counsel to the indemnified parties shall be selected by the Underwriters, and, in the case of parties indemnified pursuant to Section 7(b), counsel to the indemnified parties shall be selected by CarMax LLC or the Depositor. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. 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 and the respective officers, directors, agents and employees of each such person and each Underwriter 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 and the respective officers, directors, agents and employees of each such person and each of CarMax LLC and the Depositor 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, the effect of which is such as to make it, in the judgment of the Representative, impracticable to market any Class of Notes or to enforce contracts for the sale of any Class of Notes, (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, 13, 14 and 15 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 thenon-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 such24-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, thenon-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 allnon-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 anynon-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.

Section 12.Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.
