 ADMINISTRATION AND SERVICING OF RECEIVABLES AND 
 OTHER TRUST PROPERTY 
 SECTION 3.1 Duties of Servicer and Backup Servicer. 
 (a) The Servicer shall administer the Receivables
with reasonable care. The Servicer’s duties shall include, but not be limited to, the collection and posting of all payments, responding to inquiries by Obligors on the Receivables, or by federal, State or local governmental authorities,
investigating delinquencies, reporting tax information to Obligors,

  

 27 








 
furnishing monthly and annual statements to the Owner Trustee and the Indenture Trustee with respect to distributions and providing collection and repossession services in the event of Obligor
default. In performing its duties as Servicer hereunder, the Servicer shall use reasonable care and exercise that degree of skill and attention that the Servicer exercises with respect to all comparable motor vehicle retail installment sale
contracts that it services for itself or others. Subject to the foregoing and to Section 3.2, the Servicer shall follow its customary standards, policies, practices and procedures in performing its duties hereunder as Servicer. Without limiting
the generality of the foregoing, the Servicer is hereby authorized and empowered to execute and deliver, on behalf of itself, the Depositor, the Backup Servicer, the Trust, the Owner Trustee, the Indenture Trustee, the Certificateholders, the
Noteholders or any one or more of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge, and all other comparable instruments, with respect to the Receivables or the Financed Vehicles, all in
accordance with this Agreement; provided, however, that, notwithstanding the foregoing, the Servicer shall not, except pursuant to an order from a court of competent jurisdiction, release an Obligor from payment of any unpaid amount
under any Receivable or waive the right to collect the unpaid balance (including accrued interest) of any Receivable from the related Obligor, except in connection with a de minimis deficiency which the Servicer would not attempt to collect in
accordance with its customary procedures, in which event the Servicer shall indemnify the Trust for such deficiency. If the Servicer shall commence a legal proceeding to enforce a Receivable, the Owner Trustee shall thereupon be deemed to have
automatically assigned such Receivable to the Servicer, which assignment shall be solely for purposes of collection. If in any enforcement suit or legal proceeding it shall be held that the Servicer may not enforce a Receivable on the ground that it
shall not be a real party in interest or a holder entitled to enforce such Receivable, the Owner Trustee shall, at the Servicer’s expense and written direction, take steps to enforce such Receivable, including bringing suit in its name or the
names of the Indenture Trustee, the Certificateholders, the Noteholders or any of them. The Owner Trustee shall execute and deliver to the Servicer any powers of attorney and other documents as shall be prepared by the Servicer and reasonably
necessary or appropriate to enable the Servicer to carry out its servicing and administrative duties hereunder. The Servicer, at its expense, shall obtain on behalf of the Trust or the Owner Trustee all licenses, if any, required by the laws of any
jurisdiction to be held by the Trust or the Owner Trustee in connection with ownership of the Receivables and shall make all filings and pay all fees as may be required in connection therewith during the term hereof. If the Servicer fails to perform
its obligations under this Agreement and the Backup Servicer is appointed as successor Servicer in accordance with Section 8.2, the Backup Servicer shall be responsible for the Servicer’s duties under this Agreement except as specified in
Section 8.2; provided, however, that the Backup Servicer shall not be liable for the terminated Servicer’s failure to perform such obligations. 
 (b) The Backup Servicer and the Servicer, as applicable, shall have the following duties: (i) not less than once during any 12-month period, the Backup Servicer shall conduct an on-site visit of the
Servicer’s servicing operations, meeting with appropriate operations personnel to discuss any changes in processes and procedures that have occurred since the last on-site visit, and (ii) not less than once during any 12-month period, the
Backup Servicer shall update or amend its data-mapping with respect to the computer systems used by the Servicer to service the Receivables by effecting a data-map refresh; provided, however, that the Backup Servicer shall only be
required to effect a data-map refresh upon receipt of written notice from the Servicer that one or more fields included in the Monthly Tape or confirmed in the Backup Servicer’s original data-mapping have been updated or amended. Each on-site
visit referred to in clause (i) above shall be at the cost of CarMax.

 SECTION 3.2 Collection and Allocation of Receivable Payments. The Servicer shall
make reasonable efforts to collect all payments called for under the terms and provisions of the Receivables as and when the same shall become due and otherwise act with respect to the Receivables and the other Trust Property in such manner as will,
in the reasonable judgment of the Servicer, maximize the amount to be received by the Trust with respect thereto and in accordance with the standard of care required by Section 3.1. The Servicer shall allocate collections on or in respect of
the Receivables between principal and interest in accordance with the customary servicing practices and procedures it follows with respect to all comparable motor vehicle retail installment sale contracts that it services for itself or others. The
Servicer shall not increase or decrease the number or amount of any Scheduled Payment, the Amount Financed under any Receivable or the APR of any Receivable, or extend, rewrite or otherwise modify the payment terms of any Receivable;
provided, however, that the Servicer may extend the due date for one or more payments due on any Receivable for credit-related reasons that would be acceptable to the Servicer with respect to comparable motor vehicle retail installment
sale contracts that it services for itself or others and in accordance with its customary standards, policies, practices and procedures if the cumulative extensions with respect to any Receivable shall not cause the term of such Receivable to extend
beyond the Final Scheduled Maturity Date. If the Servicer fails to comply with the provisions of the preceding sentence, the Servicer shall be required to purchase each Receivable affected thereby for the related Purchase Amount, in the manner
specified in Section 3.7, as of the close of the Collection Period during which such failure occurs. The Servicer may, in its discretion (but only in accordance with its customary standards, policies, practices and procedures), waive any late
payment charge or any other fee that may be collected in the ordinary course of servicing a Receivable. 
 SECTION 3.3
Realization upon Receivables. The Servicer shall use reasonable efforts on behalf of the Trust, in accordance with the standard of care required under Section 3.1, to repossess or otherwise convert the ownership of each Financed Vehicle
securing a Defaulted Receivable. In taking such action, the Servicer shall follow such customary practices and procedures as it shall deem necessary or advisable in its servicing of comparable motor vehicle retail installment sale contracts and as
are otherwise consistent with the standard of care required under Section 3.1. The Servicer shall be entitled to recover all reasonable expenses incurred by it in the course of repossessing and liquidating a Financed Vehicle into cash proceeds,
but only out of the cash proceeds of such Financed Vehicle and any deficiency obtained from the related Obligor. If a Financed Vehicle shall have suffered damage, the Servicer shall not expend funds in connection with the repair or the repossession
of such Financed Vehicle unless it shall determine in its discretion that such repair and/or repossession will increase the Liquidation Proceeds received with respect to the related Receivable. 
 SECTION 3.4 Physical Damage Insurance. The Servicer shall follow its customary practices and procedures to determine whether or
not each Obligor shall have maintained physical damage insurance covering the related Financed Vehicle. 
  

 29 








 SECTION 3.5 Maintenance of Security Interests in Financed Vehicles. The Servicer
shall take such steps, in accordance with the standard of care required under Section 3.1, as are necessary to maintain perfection of the security interest created by each Receivable in the related Financed Vehicle at all times. The Trust
hereby authorizes the Servicer, and the Servicer hereby agrees, to take such steps as are necessary to re-perfect such security interest on behalf of the Trust and the Indenture Trustee in the event the Servicer receives notice of, or otherwise has
actual knowledge of, the fact that such security interest is not perfected as a result of the relocation of a Financed Vehicle or for any other reason. The Servicer shall not release, in whole or in part, any security interest in a Financed Vehicle
created by the related Receivable except as permitted herein or in accordance with its customary standards, policies, practices and procedures. 
 SECTION 3.6 Amendment of Receivable Terms. The Servicer shall not impair in any material respect the rights of the Depositor, the Trust, the Owner Trustee, the Indenture Trustee, the
Certificateholders or the Noteholders in the Receivables or, except as permitted under Section 3.2, otherwise amend or alter the terms of the Receivables if, as a result of such amendment or alteration, the interests of the Depositor, the
Trust, the Owner Trustee, the Indenture Trustee, the Certificateholders or the Noteholders hereunder would be materially adversely affected. 
 SECTION 3.7 Purchase by Servicer upon Breach. The Depositor, the Servicer, the Backup Servicer or the Owner Trustee, as the case may be, shall inform the other parties to this Agreement, the
Seller and the Indenture Trustee promptly, in writing, upon the discovery of any breach of Section 3.2, 3.5 or 3.6. If such breach shall not have been cured by the close of business on the last day of the Collection Period which includes the
30th day after the date on which the Servicer becomes aware of, or receives written notice from the Depositor, the Backup Servicer or the Owner Trustee of, such breach, and such breach materially and adversely affects the interest of the Trust in a
Receivable, the Servicer shall purchase such Receivable from the Trust on the Distribution Date following such Collection Period; provided, however, that, with respect to a breach of Section 3.2, the Servicer shall purchase the
affected Receivable from the Trust at the end of the Collection Period in which such breach occurs. In consideration of the purchase of a Receivable hereunder, the Servicer shall remit the Purchase Amount of such Receivable in the manner specified
in Section 4.5. The sole remedy of the Backup Servicer, the Trust, the Owner Trustee, the Indenture Trustee, the Noteholders and the Certificateholders with respect to a breach of Section 3.2, 3.5 or 3.6 shall be to require the Servicer to

Investments that mature not later than the Business Day preceding the Distribution Date following the Collection Period during which such investment is made. All such Permitted Investments shall be held to maturity. If the Collection Account is no
longer to be maintained at the Indenture Trustee, the Servicer shall, with the Indenture Trustee’s assistance as necessary, promptly (and in any case within ten (10) calendar days or such longer period not to exceed thirty
(30) calendar days as to which each Rating Agency shall consent) cause the Collection Account to be moved to an Eligible Institution. The Servicer shall promptly notify the Indenture Trustee and the Owner Trustee of any change in the account

Certificate Payment Account shall be held in trust for the benefit of the Certificateholders. The Certificate Payment Account shall be under the sole dominion and control of the Owner Trustee; provided, however, that the Servicer may
direct the Indenture Trustee in writing to make deposits to the Certificate Payment Account in accordance with this Agreement and the Indenture and may direct the Owner Trustee to make withdrawals from the Certificate Payment Account in accordance

event after the close of business on the second Business Day after such receipt; provided, however, that for so long as (i) CarMax is the Servicer, (ii) no Event of Servicing Termination shall have occurred and be continuing
and (iii) the Rating Agency Condition shall have been satisfied (each, a “Monthly Remittance Condition”), the Servicer may remit any such amounts received during any Collection Period to the Collection Account in immediately
available funds on the Business Day preceding the Distribution Date following such Collection Period (it being understood that the Monthly Remittance Condition has not been satisfied as of the Closing Date); provided further, that if
any such amounts (including Liquidation Proceeds and all amounts received by the Servicer in connection with the repossession and sale of a Financed Vehicle (whether or not the related Receivable has been classified as a Defaulted Receivable)) are
received in respect of a Receivable as to which there is an unreimbursed Simple Interest Advance, the Servicer shall retain such amounts to the extent of such unreimbursed Simple Interest Advance (and shall apply the amount retained to reimburse
itself for such unreimbursed Simple Interest Advance) and shall remit the balance of such amounts to the Collection Account; and, provided further, that the Servicer shall, if it determines that it has made an Unreimbursed Servicer
Advance, retain amounts received on or in respect of the Receivables to the extent set forth in Section 4.4(b). The Owner Trustee and the Indenture Trustee shall not be deemed to have knowledge of any event or circumstance under clause
(ii) or (iii) of the definition of Monthly Remittance Condition that would require daily remittance by the Servicer to the Collection Account unless the Owner Trustee or the Indenture Trustee, as applicable, has received notice of such
event or circumstance from the Depositor or the Servicer in an Officer’s Certificate or written notice of such event or circumstance from the Holders of

  

 35 








 
Notes evidencing not less than 25% of the Note Balance of the Controlling Class or unless a Responsible Officer of the Owner Trustee or the Indenture Trustee, as applicable, has actual knowledge
of such event or circumstance. The Servicer shall remit to the Collection Account on the Closing Date all amounts received by the Servicer on or in respect of the Receivables (including Liquidation Proceeds and all amounts received by the Servicer

 SECTION 4.3 Application of Collections. For purposes of this Agreement, all amounts
received on or in respect of a Receivable during any Collection Period (including Liquidation Proceeds and all amounts received by the Servicer in connection with the repossession and sale of a Financed Vehicle (whether or not the related Receivable

with the Simple Interest Method. 
 SECTION 4.4 Simple Interest Advances and Unreimbursed Servicer Advances.

 (a) If, as of the end of any Collection Period, one or more payments of Monthly P&I due under any Receivable (other than
a Defaulted Receivable) outstanding at the end of such Collection Period shall not have been received by the Servicer and remitted to the Collection Account pursuant to Section 4.2, the Servicer may, at its option, make, on the Business Day
preceding the Distribution Date immediately following such Collection Period, a Simple Interest Advance with respect to such Receivable by depositing in or crediting to the Collection Account the amount of Monthly P&I allocable to interest
scheduled to have been paid during such Collection Period, assuming that such Receivable was paid on its due date, minus the amount of Monthly P&I actually received and allocated to interest, if any, with respect to such Receivable during
such Collection Period. 
 (b) If the Servicer determines that it has made an Unreimbursed Servicer Advance, the Servicer shall
reimburse itself for such Unreimbursed Servicer Advance from unrelated amounts received by the Servicer on or in respect of the Receivables (including Liquidation Proceeds and all amounts received by the Servicer in connection with the repossession

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

at one or more depository institutions having the Required Rating and each such deposit account shall be subject to the exclusive custody and control of the Indenture Trustee and the Indenture Trustee shall have sole signature authority with respect
thereto; and 
 (iii) except for any deposit accounts specified in clause (ii) above, the Reserve Account

 (d) If the Reserve Account Amount for any Distribution Date (after giving effect to the withdrawal of the Reserve Account Draw Amount for
such Distribution Date) exceeds the Required Reserve Account Amount for such Distribution Date, the Servicer shall instruct the Indenture Trustee in writing to distribute the amount of such excess (i) first, to the Note Payment Account, for
payment of principal of the Notes in the priority set forth in Section 2.8(b) of the Indenture, to the extent of any unfunded Regular Principal Distributable Amount, if any, on such Distribution Date (after giving effect to the application of
Available Funds on such Distribution Date), (ii) second, be paid to the Backup Servicer or any other Successor Servicer, as applicable, to the extent of any unfunded amounts payable pursuant to Section 2.8(a)(xii) or (xiii) of the
Indenture, if any, on such Distribution Date (after giving effect to the application of Available Funds on such Distribution Date), (iii) third, to the Certificate Payment Account for payment to the Certificateholders. The Indenture Trustee and

in the opinion of such counsel, no such action shall be necessary to fully preserve and protect such interest. The Servicer shall provide prior written notice of any merger, conversion, consolidation or succession pursuant to this Section 7.4
to the Rating Agencies. Notwithstanding anything to the contrary contained herein, the execution of the foregoing agreement of assumption and compliance with clauses (x) and (y) above shall be conditions to the consummation of the
transactions referred to in clauses (i), (ii) and (iii) above. 
 (b) Any Person (i) into which the Backup
Servicer shall be merged or consolidated, (ii) resulting from any merger, conversion or consolidation to which the Backup Servicer shall be a party or (iii) that shall succeed by purchase and assumption to all or substantially all of the
business of the Backup Servicer, which Person in any of the foregoing cases is an Eligible Servicer and executes an agreement of assumption to perform every obligation of the Backup Servicer under this Agreement, shall be the successor to the Backup
Servicer under this Agreement without the execution or filing of any other document or any further act on the part of any of the parties to this Agreement.

 SECTION 7.5 Limitation on Liability of Servicer, Backup Servicer and Others.

 (a) Neither the Servicer nor the Backup Servicer nor any of the directors, officers, employees or agents of the Servicer or
the Backup Servicer shall be under any liability to the Trust, the Noteholders or the Certificateholders for any action taken or for refraining from the taking of any action pursuant to this Agreement or for errors in judgment; provided,
however, that this provision shall not protect the Servicer or the Backup Servicer or any such Person against any liability that would otherwise be imposed by reason of willful misfeasance or bad faith in the performance of duties or by
reason of reckless disregard of obligations and duties under this Agreement, or by reason of negligence in the performance of duties under this Agreement (except for errors in judgment). The Servicer and the Backup Servicer, and their respective
directors, officers, employees and agents, may rely in good faith on the advice of counsel or on any document of any kind prima facie properly executed and submitted by any Person in respect of any matters arising under this Agreement.

 (b) The Servicer shall not be under any obligation to appear in, prosecute or defend any legal action that shall not be
incidental to its duties to service the Receivables in accordance with this Agreement and that in its opinion may involve it in any expense or liability; provided, however, that the Servicer may undertake any reasonable action that it
may deem necessary or desirable in respect of this Agreement and the rights and duties of the parties to this Agreement and the interests of the Noteholders and the Certificateholders under this Agreement. In such event, the legal expenses and costs
of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Servicer. 
 (c) The Backup
Servicer shall not be liable for any obligation of the Servicer contained in this Agreement or for any errors of the Servicer contained in any computer tape, certificate or other data or document delivered to the Backup Servicer hereunder or on
which the Backup Servicer must rely in order to perform its obligations hereunder, and the Owner Trustee, the Indenture Trustee, the Depositor and the Noteholders shall look only to the Servicer to perform such obligations. The Owner Trustee, the
Indenture Trustee, the Backup Servicer, the Depositor and the Noteholders shall have no responsibility and shall not be in default hereunder or incur any liability for any failure, error, malfunction or delay in carrying out any of their respective
duties under this Agreement if such failure, error, malfunction or delay results from the Backup Servicer acting in accordance with information prepared or supplied by a Person other than the Backup Servicer (or its contractual agents) or the
failure of any such other Person to prepare or provide such information. The Backup Servicer shall have no responsibility, shall not be in default and shall incur no liability for (i) any act or failure to act of any third party (other than its
contractual agents), including the Servicer or the Noteholders, (ii) any inaccuracy or omission in a notice or communication received by the Backup Servicer from any third party (other than its contractual agents), (iii) the invalidity or
unenforceability of any Receivable under applicable law, (iv) the breach or inaccuracy of any representation or warranty made with respect to any Receivable, or (v) the acts or omissions of any successor Backup Servicer. 
  

 53 








 (d) The parties expressly acknowledge and consent to Wells Fargo Bank, National Association,
acting in the dual capacity of Backup Servicer and Indenture Trustee and in the possible dual capacity of successor Servicer and Indenture Trustee. Wells Fargo Bank, National Association, may, in such dual or other capacity, discharge its separate
functions fully, without hindrance or regard to conflict of interest principles, duty of loyalty principles or other breach of fiduciary duties to the extent that any such conflict or breach arises from the performance by Wells Fargo Bank, National
Association, of express duties set forth in this Agreement in any of such capacities, all of which defenses, claims or assertions are hereby expressly waived by the other parties hereto and the Noteholders except in the case of gross negligence and
willful misconduct by Wells Fargo Bank, National Association. 
 SECTION 7.6 Delegation of Duties. The Servicer may
at any time delegate its duties as servicer under this Agreement to third parties; provided, however, that no such delegation shall relieve the Servicer of its responsibilities with respect to such duties and the Servicer shall be
solely responsible for the fees of any such third party. 
 SECTION 7.7 Servicer and Backup Servicer Not to Resign.

 (a) Subject to the provisions of Section 7.4(a), the Servicer shall not resign from its obligations and duties under
this Agreement except (i) upon a determination that the performance of its duties is no longer permissible under applicable law or (ii) upon the appointment of a successor Servicer and satisfaction of the Rating Agency Condition with
respect to such resignation and appointment. Any such determination permitting the resignation of the Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Depositor, the Backup Servicer, the Owner Trustee and the
Indenture Trustee. No such resignation shall become effective until the Backup Servicer or another successor Servicer shall have (i) assumed the obligations and duties of the Servicer in accordance with Section 8.2 and (ii) become the
Administrator under the Administration Agreement pursuant to Section 20 thereof. 
 (b) Subject to the provisions of
Section 7.4(b), the Backup Servicer shall not resign from its obligations and duties under this Agreement except upon a determination that the performance of its duties is no longer permissible under applicable law. Any such determination
permitting the resignation of the Backup Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Depositor, the Servicer, the Owner Trustee and the Indenture Trustee. No such resignation shall become effective until an
entity acceptable to the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class shall have assumed the responsibilities and obligations of the Backup Servicer; provided, however, that (i) in the
event a successor Backup Servicer is not appointed within sixty (60) days after the Backup Servicer has given notice of its resignation and has provided the Opinion of Counsel required by this Section 7.7(b), the Backup Servicer may
petition a court for its removal. 
 SECTION 7.8 Servicer May Own Notes or Certificates. The Servicer, and any
Affiliate of the Servicer, may, in its individual or any other capacity, become the owner or pledgee of Notes or Certificates with the same rights as it would have if it were not the Servicer or an Affiliate of the Servicer, except as otherwise
expressly provided herein (including in the definition of “Note Balance”) or in the other Transaction Documents. Except as otherwise

  

 54 








 
expressly provided herein (including in the definition of “Note Balance”) or in the other Transaction Documents, Notes and Certificates so owned by or pledged to the Servicer or such
Affiliate shall have an equal and proportionate benefit under the provisions of this Agreement and the other Transaction Documents, without preference, priority or distinction as among the Notes and the Certificates. 
 ARTICLE VIII 
 SERVICING TERMINATION 
 SECTION 8.1 Events of Servicing Termination. 
 (a) The occurrence of any one of the following events shall constitute an event of servicing termination hereunder (each, an “Event
of Servicing Termination”): 
 (i) any failure by the Servicer to deliver to the Backup Servicer (unless
the Backup Servicer is then acting as the successor Servicer), the Owner Trustee, the Indenture Trustee, the Depositor, the Seller, each Paying Agent or the Rating Agencies the Servicer’s Certificate for any Collection Period, which failure
shall continue unremedied beyond the earlier of three (3) Business Days following the date such Servicer’s Certificate was required to be delivered and the Business Day preceding the related Distribution Date, or any failure by the
Servicer to make any required payment or deposit under this Agreement, which failure shall continue unremedied beyond the earlier of five (5) Business Days following the date such payment or deposit was due and, in the case of a payment or
deposit to be made no later than a Distribution Date or the Business Day preceding a Distribution Date, such Distribution Date or preceding Business Day, as applicable; or 
 (ii) any failure by the Servicer duly to observe or perform in any material respect any other covenant or agreement in this
Agreement, which failure shall materially and adversely affect the rights of the Depositor or the Noteholders and shall continue unremedied for a period of sixty (60) days after the date on which written notice of such failure, requiring the
same to be remedied, shall have been given to the Servicer by the Depositor, the Backup Servicer, the Owner Trustee or the Indenture Trustee or to the Depositor, the Seller, the Servicer, the Backup Servicer, the Owner Trustee and the Indenture
Trustee by the Holders of Notes evidencing not less than 25% of the Note Balance of the Controlling Class; or 
 (iii) any representation or warranty of the Servicer made in this Agreement or in any certificate delivered pursuant hereto or in connection herewith, other than any representation and warranty relating to a Receivable that has been
purchased by the Servicer, proving to have been incorrect in any material respect as of the time when the same shall have been made, and the circumstance or condition in respect of which such representation or warranty was incorrect shall not have
been eliminated or otherwise cured for a period of thirty (30) days after the date on which written notice of such circumstance or condition, requiring the same to be eliminated or cured, shall have been given to the Servicer by the Depositor,
the Backup Servicer, the Owner Trustee or the Indenture Trustee or to the Depositor, the Seller, the Servicer, the Backup Servicer, the Owner Trustee and the Indenture Trustee by the Holders of Notes evidencing not less than 25% of the Note Balance
of the Controlling Class; or 
  

 55 








 (iv) the entry of a decree or order by a court or agency or supervisory
authority of competent jurisdiction for the appointment of a conservator, receiver, liquidator or trustee for the Servicer in any bankruptcy, insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceeding, or for the
winding up or liquidation of its affairs, which decree or order continues unstayed and in effect for a period of sixty (60) consecutive days; or 
 (v) the consent by the Servicer to the appointment of a conservator, receiver, liquidator or trustee in any bankruptcy, insolvency, readjustment of debt, marshalling of assets and liabilities or similar
proceeding of or relating to the Servicer or relating to substantially all of its property, the admission in writing by the Servicer of its inability to pay its debts generally as they become due, the filing by the Servicer of a petition to take
advantage of any applicable bankruptcy, insolvency or reorganization statute, the making by the Servicer of an assignment for the benefit of its creditors or the voluntary suspension by the Servicer of payment of its obligations; or 
 (vi) if CarMax is the Servicer, the occurrence, as of any Distribution Date, of a Special Unrated Servicer Tangible Net Worth
Event. 
 If an Event of Servicing Termination shall have occurred and be continuing, the Indenture Trustee or the Holders of
Notes evidencing not less than 51% of the Note Balance of the Controlling Class, in each case by notice then given in writing to the Depositor, the Servicer and the Backup Servicer (with a copy to the Indenture Trustee and the Owner Trustee if given
by the Noteholders), may terminate all of the rights and obligations of the Servicer under this Agreement; provided, however, that the indemnification obligations of the Servicer under Section 7.3 shall survive such termination.
On or after the receipt by the Servicer of such written notice, all authority and power of the Servicer under this Agreement, whether with respect to the Notes, the Certificates, the Trust Property or otherwise, shall pass to and be vested in the
Backup Servicer or such other successor Servicer as may be appointed under Section 8.2; provided, however, that the Backup Servicer or such other successor Servicer shall have no liability with respect to any obligation that was
required to be performed by the terminated Servicer prior to the appointment of the Backup Servicer or such other successor Servicer or any claim of any third party based on any alleged action or inaction of the terminated Servicer. 
 (b) The Indenture Trustee and the Owner Trustee shall have no obligation to notify the Noteholders, the Certificateholders or any other
Person of the occurrence of any event specified in Section 8.1(a) prior to the continuance of such event through the end of any cure period specified in Section 8.1(a). 
 SECTION 8.2 Appointment of Successor Servicer. 
 (a) Upon the resignation of the Servicer pursuant to Section 7.7 or the termination of the Servicer pursuant to Section 8.1, the Backup Servicer shall be the successor in all respects to the
outgoing Servicer in its capacity as Servicer under this Agreement and shall be

  

 56 








 
subject to all the obligations and duties placed on the Servicer by the terms and provisions of this Agreement; provided, however, that the Backup Servicer, as successor Servicer,
shall not, in any event, make any Simple Interest Advances pursuant to Section 4.4, shall have no obligations pursuant to Section 3.7 with respect to the repurchase of Receivables and shall have no obligations pursuant to Section 3.8
with respect to the fees and expenses of the Owner Trustee or the Indenture Trustee or the fees and expenses of the Owner Trustee’s attorneys or the Indenture Trustee’s attorneys. Notwithstanding the foregoing, if the Backup Servicer is
the outgoing Servicer or shall be unwilling or legally unable to act as successor Servicer, the Indenture Trustee shall appoint, or petition a court of competent jurisdiction to appoint, an Eligible Servicer as the successor Servicer under this
Agreement. The Indenture Trustee and such successor Servicer shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. 
 (b) The successor Servicer is authorized and empowered to execute and deliver, on behalf of the outgoing Servicer, as attorney-in-fact or
otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the transfer of servicing to the successor Servicer, whether to complete the transfer and endorsement of the
Receivable Files or the certificates of title to the Financed Vehicles or otherwise. The outgoing Servicer shall cooperate with the Indenture Trustee, the Owner Trustee and such successor Servicer in effecting the termination of its responsibilities
and rights as Servicer under this Agreement, including the transfer to the successor Servicer for administration of all cash amounts that are at the time held by the outgoing Servicer for deposit or thereafter shall be received with respect to a
Receivable, all Receivable Files and all information or documents that the successor Servicer may require. In addition, the outgoing Servicer shall transfer its electronic records relating to the Receivables to the successor Servicer in such
electronic form as the successor Servicer may reasonably request. All reasonable costs and expenses (including reasonable attorneys’ fees) incurred or payable by the successor Servicer in connection with the transfer of servicing (whether due
to termination, resignation or otherwise), including allowable compensation of employees and overhead costs incurred or payable in connection with the transfer of the Receivable Files or any amendment to this Agreement required in connection with
the transfer of servicing, (the “Transition Costs”) shall be paid by any applicable then outgoing Servicer other than the Backup Servicer upon presentation of reasonable documentation of such costs and expenses. Any such Transition
Costs not paid by the outgoing Servicer shall be paid solely from the application of Available Funds pursuant to Section 2.8(a)(ii) and (xii) or Section 5.4(b)(ii) of the Indenture, as applicable. 
 (c) If the Backup Servicer is appointed successor Servicer pursuant to Section 8.2(a), it shall be entitled to such compensation
(whether payable out of the Collection Account or otherwise) as the outgoing Servicer would have been entitled to under this Agreement if such outgoing Servicer had not resigned or been terminated. If a Person other than the Backup Servicer is
appointed successor Servicer pursuant to Section 8.2(a), the Indenture Trustee may make such arrangements for the compensation of such successor Servicer out of collections on or in respect of the Receivables as it and such successor Servicer
shall agree; provided, however, that such compensation shall not be greater than that payable to CarMax as Servicer hereunder without the prior consent of the Holders of Notes evidencing at least 51% of the Note Balance of the
Controlling Class; and, provided further, that, if a Person other than the Backup Servicer is appointed successor Servicer pursuant to Section 8.2(a) because the Backup

  

 57 








 
Servicer refuses to act as successor Servicer (in breach of the terms of this Agreement and notwithstanding that it is legally able to do so), the Backup Servicer shall be liable for any
Additional Servicing Fees with respect to such successor Servicer in an aggregate amount not to exceed $150,000 per year. Notwithstanding anything to the contrary contained herein, in no event shall the Indenture Trustee be liable for any servicing
fee or for any differential in the amount of the servicing fee paid hereunder and the amount necessary to induce any successor Servicer to act as successor Servicer hereunder other than pursuant to the preceding sentence if the Indenture Trustee is
the Backup Servicer. 
 (d) Notwithstanding anything contained in this Agreement to the contrary, the successor Servicer is
authorized to accept and rely on all of the accounting records (including computer records) and work of the prior Servicer relating to the Receivables (collectively, the “Predecessor Servicer Work Product”) without any audit or
other examination thereof, and the successor Servicer shall have no duty, responsibility, obligation or liability for the acts and omissions of the prior Servicer. If any error, inaccuracy, omission or incorrect or non-standard practice or procedure
(collectively, “Errors”) exists in any Predecessor Servicer Work Product and such Error makes it materially more difficult to service or should cause or materially contribute to the successor Servicer making or continuing any Error
(collectively, “Continuing Errors”), the successor Servicer shall have no duty, responsibility, obligation or liability for such Continuing Errors; provided, however, that the successor Servicer agrees to use its best
efforts to prevent further Continuing Errors. If the successor Servicer becomes aware of Errors or Continuing Errors, it shall, with the prior consent of the Holders of Notes evidencing at least 51% of the Note Balance of the Controlling Class, use
its best efforts to reconstruct and reconcile such data as is commercially reasonable to correct such Errors and Continuing Errors and to prevent future Continuing Errors. The successor Servicer shall be entitled to recover its costs expended in
connection with such efforts in accordance with Section 2.8(a)(ii) and (xii) of the Indenture, as applicable. 
 SECTION 8.3 Effect of Servicing Transfer. 
 (a) After a transfer of servicing hereunder, the Indenture
Trustee or successor Servicer shall notify the Obligors to make directly to the successor Servicer payments that are due under the Receivables after the effective date of such transfer. 
 (b) Except as provided in Section 8.2, after a transfer of servicing hereunder, the outgoing Servicer shall have no further obligations
with respect to the administration, servicing, custody or collection of the Receivables and the successor Servicer shall have all of such obligations, except that the outgoing Servicer will transmit or cause to be transmitted directly to the
successor Servicer for its own account, promptly on receipt and in the same form in which received, any amounts or items held by the outgoing Servicer (properly endorsed where required for the successor Servicer to collect any such items) received
as payments upon or otherwise in connection with the Receivables. 
 (c) Any successor Servicer shall provide the Depositor with
access to the Receivable Files and to the successor Servicer’s records (whether written or automated) with respect to the Receivable Files. Such access shall be afforded without charge, but only upon reasonable request and during normal
business hours at the offices of the successor Servicer.

  

 58 








 
Nothing in this Section 8.3 shall affect the obligation of the successor Servicer to observe any applicable law prohibiting disclosure of information regarding the Obligors, and the failure
of the Servicer to provide access to information as a result of such obligation shall not constitute a breach of this Section 8.3. 
 (d) Any transfer of servicing hereunder shall not constitute an assumption by the related successor Servicer of any liability of the related outgoing Servicer arising out of any breach by such outgoing
Servicer of such outgoing Servicer’s duties hereunder prior to such transfer of servicing. 
 SECTION 8.4
Notification to Noteholders, Certificateholders and Rating Agencies. Upon any notice of an Event of Servicing Termination or upon any termination of, or any appointment of a successor to, the Servicer pursuant to this Article VIII, the
Indenture Trustee shall give prompt written notice thereof to the Noteholders and the Owner Trustee shall give prompt written notice thereof to the Certificateholders and to the Rating Agencies. 
 SECTION 8.5 Waiver of Past Events of Servicing Termination. The Holders of Notes evidencing not less than 51% of the Note
Balance of the Controlling Class may, on behalf of all Noteholders, waive any Event of Servicing Termination and its consequences, except an event resulting from the failure to make any required deposits to or payments from the Collection Account,
the Note Payment Account, the Certificate Payment Account or the Reserve Account in accordance with this Agreement. Upon any such waiver of an Event of Servicing Termination, such event shall cease to exist, and shall be deemed to have been remedied
for every purpose of this Agreement. No such waiver shall extend to any subsequent or other event or impair any right arising therefrom, except to the extent expressly so waived. 
 SECTION 8.6 Repayment of Advances. If the identity of the Servicer shall change, the predecessor Servicer shall be entitled to
receive reimbursement for outstanding and unreimbursed Simple Interest Advances made pursuant to Section 4.4 by the predecessor Servicer. 
 ARTICLE IX 
 TERMINATION 
 SECTION 9.1 Optional Purchase of All Receivables. 
 (a) If, as of the last day of any Collection Period, the Pool Balance shall be less than or equal to 10% of the initial Pool Balance, the Servicer shall have the option to purchase on the following
Distribution Date the Owner Trust Estate, other than the Collection Account, the Note Payment Account, the Certificate Payment Account or the Reserve Account. To exercise such option, the Servicer shall notify the Depositor, the Backup Servicer, the
Owner Trustee, the Indenture Trustee and the Rating Agencies no later than ten (10) days prior to the Distribution Date on which such repurchase is to be effected and shall deposit into the Collection Account on the Business Day preceding such
Distribution Date an amount equal to the aggregate Purchase Amount for the Receivables, plus the appraised value of any other Trust Property, other than the Collection Account, the Note Payment Account, the Certificate Payment Account or the
Reserve Account, such value to be determined by an appraiser mutually agreed upon by the

  

 59 








 
Servicer, the Owner Trustee and the Indenture Trustee; provided, however, that the Servicer shall not be permitted to exercise such option unless the amount to be deposited in the
Collection Account pursuant to this Section 9.1(a) is at least equal to the sum of all amounts due to the Servicer under this Agreement plus all amounts due to the Backup Servicer under this Agreement plus the Note Balance
plus all accrued but unpaid interest (including any overdue interest) on the Notes plus all amounts due to the Servicer in any outstanding and unreimbursed Simple Interest Advances and any outstanding and unreimbursed Unreimbursed
Servicer Advances. Upon such payment, the Servicer shall succeed to and own all interests in and to the Trust. The aggregate Purchase Amount for such Distribution Date, plus, to the extent necessary, all amounts in the Reserve Account shall
be used to make payments in full to the Noteholders in the manner set forth in Article IV. 
 (b) [RESERVED]. 
 (c) Following the satisfaction and discharge of the Indenture and the payment in full of the principal of and interest on the Notes, the
Certificateholders shall succeed to the rights of the Noteholders hereunder and the Indenture Trustee shall continue to carry out its obligations hereunder with respect to the Certificateholders, including making distributions from the Collection
Account in accordance with Section 4.6(d) and making withdrawals from the Reserve Account in accordance with Sections 4.6(b) and 4.7. 
 ARTICLE X

 (a) This Agreement may be amended from time to time by the Depositor, the Servicer, the Backup Servicer and the Owner Trustee, on behalf of the Trust, with the consent of the Indenture Trustee, but

initial offer and sale of the Notes or to add, change or eliminate any other provisions with respect to matters or questions arising under this Agreement that are not inconsistent with the provisions of this Agreement; provided,
however, that (i) no such amendment may materially adversely affect the interests of any Noteholder and (ii) no such amendment will be permitted unless an Opinion of Counsel is delivered to the Depositor, the Owner Trustee and the

permitted unless an Opinion of Counsel is delivered to the Depositor, the Owner Trustee and

  

 60

any material adverse impact on the federal income taxation of any Notes Outstanding or any Noteholder and (y) that no such amendment may: 
 (i) increase or reduce in any manner the amount of, or accelerate or delay the timing of, or change the allocation or priority of, collections of payments on or in respect of the Receivables or

 SECTION 10.2 Protection of Title to Trust. 
 (a) The Depositor or the Servicer, or both, shall authorize and file such financing statements and cause to be authorized and filed such
continuation statements, all in such manner and in such places as may be required by law fully to preserve, maintain and protect the interest of the Trust and the Indenture Trustee for the benefit of the Noteholders in the Receivables and the
proceeds thereof. The Depositor or the Servicer, or both, shall deliver (or cause to be delivered) to the Backup Servicer, the Owner Trustee and the Indenture Trustee file-stamped copies of, or filing receipts for, any document filed as provided
above as soon as available following such filing. 
 (b) Neither the Depositor nor the Servicer shall change its name, identity
or organizational structure in any manner that would make any financing statement or continuation statement filed by the Depositor or the Servicer in accordance with Section 10.2(a) seriously misleading within the meaning of Section 9-506
of the Relevant UCC, unless it shall have given the Backup Servicer, the Owner Trustee and the Indenture Trustee at least sixty (60) days’ prior written notice thereof and shall have promptly filed such amendments to previously filed

Indenture Trustee at least sixty (60) days’ prior written notice of any change in its name, identity, organizational structure or jurisdiction of organization or any relocation of its principal place of business or chief executive office
if, as a result of such change or relocation, the applicable provisions of the Relevant UCC would require the filing of any amendment to any previously filed financing statement or continuation statement or of any new financing statement and shall
promptly file any such amendment, continuation statement or new financing statement. The Depositor shall at all times maintain its jurisdiction of organization, its principal place of business and its chief executive office within the United States.
The Servicer shall at all times maintain each office from which it shall service Receivables and each office at which the Receivable Files are located within the United States. 
 (d) The Servicer shall maintain accounts and records as to each Receivable accurately and in sufficient detail to permit (i) the reader

amounts from time to time deposited in the Collection Account and the Reserve Account in respect of such Receivable. 
 (e) The
Servicer shall maintain its computer systems so that, from and after the time of the transfer of the Receivables to the Trust pursuant to this Agreement, the Servicer’s master computer records (including any back-up archives) that refer to a
Receivable shall indicate clearly and unambiguously the interest of the Trust and the Indenture Trustee in such

  

 62 








 
Receivable and that such Receivable is owned by the Trust and has been pledged to the Indenture Trustee pursuant to the Indenture. Indication of the Trust’s and the Indenture Trustee’s
interest in a Receivable shall be deleted from or modified on the Servicer’s computer systems when, and only when, such Receivable shall have been paid in full or repurchased by the Depositor or purchased by the Servicer. 
 (f) If at any time the Depositor or the Servicer shall propose to sell, grant a security interest in or otherwise transfer any interest in
any motor vehicle retail installment sale contract to any prospective purchaser, lender or other transferee, the Servicer shall give to such prospective purchaser, lender or other transferee computer tapes, compact disks, records or print-outs
