Article 2. Duties and Responsibilities. CarMax shall employ the Associate in the position of TITLE . The specific duties of such position are set forth in the then-current written job description for such position and are incorporated herein by reference.

The terms and provisions contained in this Article 8 comprise a covenant not to compete (the “Covenant Not to Compete”). The Associate acknowledges and agrees as follows: 8.1 CarMax operates a unique business concept regarding the sale and servicing of new and used vehicles in a highly competitive industry. 8.2 CarMax’s competitors have attempted to duplicate CarMax’s business concept in various markets throughout the United States, including markets where CarMax does not currently have a business location, and may continue to do so. 8.3 In connection with the Associate’s employment with CarMax, the Associate will receive access to, and training regarding, CarMax’s business concept and will, accordingly, acquire commercially valuable knowledge of and insight into CarMax’s operations and CarMax’s proprietary and confidential information, any of which if made available to any Competitor (as defined below) could place CarMax at a competitive disadvantage. 8.4 In order to protect CarMax’s legitimate business interests from Competitors (as defined below) and to protect CarMax’s critical interest in its proprietary and confidential information, the Associate covenants and agrees as follows: During the Associate’s employment with CarMax and for a period of twenty-four (24) months following the last day of the Associate’s employment (the “Restricted Period”), the Associate will not, directly or indirectly, compete with CarMax by acting “in a competitive capacity” (as defined below), for, or on behalf of, any person or entity operating or developing, during the Restricted Period, a business that provides or intends to provide activities, products or services that are the same or substantially similar to, and competitive with, the business of CarMax as of Associate’s last day of employment with CarMax (each, a “Competitor”) within any Metropolitan Statistical Area (as defined by the United States Office of Management and Budget) in which CarMax has a retail store site as of Associate’s last day of employment. Such Competitors include, but are not limited to: Sonic Automotive, Inc.; Lithia Motors, Inc.; Group 1 Automotive, Inc.; AutoNation, Inc.; Penske Automotive Group, Inc.; Xxxxxx Automotive Group, Inc.; Xxxxxxxx Automotive Group; Auction Direct USA, L.P.; AutoAmerica, Inc.; Off Lease Only, Inc.; Carvana, LLC; Carvana Group, LLC; AutoMatch USA, LLC; DriveTime Car Sales Company, LLC; DriveTime Automotive Group, Inc.; Hertz Global Holdings, Inc.; Enterprise Holdings, Inc.; Avis Budget Group, Inc.; Xxx Automotive, Inc.; Classified

9 Ventures, LLC; TrueCar, Inc.; Dealer Dot Com, Inc.; CarGurus, Inc.; Blinker, Inc.; KAR Auction Services, Inc.; Xxxx.xxx; TrueCar, Inc.; Vroom, Inc.; Shift Technologies, Inc.; ACV Auctions, Inc.; CarOffer, LLC; Copart, Inc.; XxXxxXxxXxx.xxx; and XxxxXxXxxXXX.xxx, and any automotive retail operation affiliated with, owned, operated, or controlled by Berkshire Hathaway Inc.; Carrefour S.A.; and/or Gulliver International Co., Ltd. 8.5 A business, including any Competitor, or any of its respective subsidiaries or affiliates, will not be considered to be in competition with CarMax for purposes of Article 8 if the business, or operating unit of the business, or its respective subsidiaries or affiliates, by which the Associate will be or is employed (i) does not have within the twenty-four (24) months preceding the Associate’s termination of employment with CarMax, annual gross revenues (calculated on a rolling 12-month basis) of at least $5,000,000 derived from the sale and servicing of new or used vehicles; or (ii) is not projected (by the business or operating unit of the business) to have within the twenty-four (24) months following the Associate’s termination of employment with CarMax, annual gross revenues (regardless of how calculated) of at least $5,000,000 derived from the sale and servicing of new or used vehicles. 8.6 Acting “in a competitive capacity” shall mean providing to a Competitor, directly or indirectly, the same or substantially similar services that the Associate provided to CarMax at any time during Associate’s last twenty-four (24) months of employment. 8.7 Nothing herein shall prevent or restrict the Associate from working for any person in any role or in any capacity that is not in competition with CarMax. 8.8 Notwithstanding the foregoing, nothing herein shall be deemed to prevent or limit the right of the Associate to invest in the capital stock or other securities of any corporation whose stock or securities are regularly traded on any public exchange. 8.9 The Associate and CarMax have examined in detail the Covenant Not to Compete contained in this Article 8 and each agrees that the restraint imposed upon the Associate is reasonable in light of the legitimate business interests of CarMax and is not unduly harsh or burdensome with respect to the Associate’s ability to earn a livelihood. If any provision of the Covenant Not to Compete relating to the time period, geographic area or scope of restricted activities shall be declared by a court of competent jurisdiction to exceed the maximum time period, geographic area or scope of activities, as applicable, that such court deems reasonable and enforceable, then such time period, geographic area or scope of activities shall be deemed to be, and thereafter shall become, the maximum time period, scope of activities or largest geographic area that such court deems reasonable and enforceable and this Agreement shall automatically be considered to have been amended and revised to reflect such determination. 8.10 The Associate and CarMax acknowledge that the Associate’s services are of a special, extraordinary, and intellectual character that gives the Associate unique value, and that CarMax’s business is highly competitive, and that violation of the Covenant Not to Compete provided herein would cause immediate, immeasurable, and irreparable harm,

10 loss, and damage to CarMax not adequately compensable by a monetary award. In the event of any breach or threatened breach by the Associate of the Covenant Not to Compete, CarMax shall be entitled to such equitable and injunctive relief as may be available to restrain the Associate from violating the provisions hereof. Nothing herein shall be construed as prohibiting CarMax from pursuing any other remedies available at law or in equity for such breach or threatened breach, including the recovery of damages and the immediate termination of the employment of the Associate hereunder for Cause. Article 9. Non-Solicitation of Employees. The Associate agrees that during the Associate’s employment with CarMax and for a period of twenty-four (24) months following the last day of the Associate’s employment, the Associate shall not, directly or indirectly, solicit or induce, or attempt to solicit or induce, any employee of CarMax with whom the Associate had material business-related contact on behalf of CarMax, to leave employment with CarMax for any reason whatsoever (the “Covenant Not to Solicit”). For purposes of this Article 9, employee shall mean any individual employed by CarMax. Article 10. Confidentiality. The terms and provisions contained in this Article 10 comprise a covenant of confidentiality (the “Covenant of Confidentiality”). The Associate understands and agrees that any and all Protected Information is the property of CarMax and is essential to the protection of CarMax’s goodwill and to the maintenance of CarMax’s competitive position and accordingly should be kept secret. For purposes of this Agreement, “Protected Information” means trade secrets, confidential and proprietary business information of or about CarMax, and any other information of CarMax, including technical data, processes, know-how, financial data, analyses, forecasts, plans, operations information and data, customer lists (including potential customers) and information, marketing plans, materials and information, product and service information, accounts and xxxxxxxx information, sales transaction data, sales documents and information, discoveries, ideas, concepts, designs, drawings, specifications, techniques, models, information systems data and materials, computer software or hardware, data analyses and compilations, source code, object code, documentation, diagrams, flow charts, research, procedures, methods, systems, programs, price lists, pricing policies, supplier and distributor information, sources of supply, internal memoranda, promotional plans, internal policies, purchasing information, operating methods and procedures, training materials, and any products and services which may be developed from time to time by CarMax and its agents or employees, including the Associate; provided, however, that information that is in the public domain (other than as a result of a breach of this Agreement), approved for release by CarMax or lawfully obtained from third parties who are not bound by a confidentiality agreement with CarMax, is not Protected Information. CarMax has advised the Associate and the Associate acknowledges that it is the policy of CarMax to maintain as secret and confidential all Protected Information, and that Protected Information has been and will be developed at substantial cost to and effort by CarMax. The Associate agrees to hold in strict confidence and safeguard any and all Protected Information

11 accessed or accessible by the Associate during the Associate’s employment. The Associate shall not, without the prior written consent of CarMax, at any time, directly or indirectly, divulge, furnish, use, disclose or make accessible to any person, firm, corporation, association, or other entity (otherwise than as may be required in the regular course of the Associate’s employment with CarMax), any Protected Information, or cause any such Protected Information to enter the public domain. Nothing contained in this Article 10 is intended to reduce in any way the protection available to CarMax pursuant to the Uniform Trade Secrets Act as adopted in Virginia or any other state or other applicable laws that prohibit the misuse or disclosure of confidential or proprietary information. Unless lengthened by the application of the Virginia Uniform Trade Secrets Act or other applicable law, the restrictions in Article 10 shall remain in effect during Associate’s employment and for five (5) years thereafter. Article 11. Return of CarMax Property. Upon the termination (for any reason) of the Associate’s employment with CarMax, the Associate shall deliver promptly to CarMax all CarMax property including, without limitation, any automobiles, equipment, credit cards, keys, building access cards, identification, cellular phones, computers, software, CD ROMs, customer lists, and all Protected Information as defined in Article 10 of this Agreement. The Associate further agrees not to take or extract any portion of any such information and/or materials in written, computer, electronic or any other reproducible form. Article 12. Monies Owed. To the extent that the Associate owes CarMax any monies at the time of termination of employment, the Associate authorizes and agrees to have CarMax withhold such amounts owed from the Associate’s final paycheck, to the maximum extent permitted by applicable law. Article 13. Work Product. (a) All work product prepared by the Associate in connection with performing job duties for CarMax shall be the sole property of CarMax. CarMax shall have full and exclusive rights to use, reproduce, publish, or otherwise profit from such work product, as CarMax deems appropriate. The Associate agrees to assist CarMax, or any agent designated by CarMax, at any time and at no cost to the Associate, in obtaining any patents, copyrights, trademarks or other forms of legal protection for any such work product. (b) To the extent that any work product is deemed in any way to fall within the definition of “work made for hire,” as such term is defined in 17 U.S.C. § 101, such work product shall be considered “work made for hire,” the copyright of which shall be owned solely, completely and exclusively by CarMax. (c) For the purpose of this Agreement, the term “work product” includes, but is not limited to, reports, manuals, inventions, improvements, designs, formulae,

12 processes, techniques, methods, computer software, proposals, technical solutions, patents, training materials, other works of authorship, innovations, and enhancements created by the Associate or the Associate’s staff. Article 14. Dispute Resolution. Except for actions initiated by CarMax to enjoin a breach by the Associate, and/or recover damages from the Associate, related to the Covenant Not to Compete (Article 8), the Covenant Not to Solicit (Article 9) or the Covenant of Confidentiality (Article 10) (collectively, the “Restrictive Covenants”), or Forfeiture and Recoupment (Article 3.2), which action(s) CarMax may bring in an appropriate court of law or equity, any disagreement between the Associate and CarMax concerning anything covered by this Agreement or concerning other terms or conditions of the Associate’s employment or the termination of the Associate’s employment will be settled by final and binding arbitration pursuant to CarMax’s Dispute Resolution Rules and Procedures in effect at the time the disagreement or dispute arises or at the time of termination in the event the Associate’s employment terminated. The decision of the arbitrator will be final and binding on both the Associate and CarMax and may be enforced in a court of appropriate jurisdiction. Article 15. General Provisions. 15.1 Notices.
