binding payment obligation in writing of the related Obligor, enforceable by the holder thereof in all material respects in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, liquidation or
other similar laws affecting the enforcement of creditors’ rights generally and by general principles of equity. 
 (e)
No Government Obligor. No Receivable is due from the United States or any State or from any agency, department or instrumentality of the United States or any State. 
 (f) Security Interest in Financed Vehicles. Immediately prior to the transfer of the Receivables by the Seller to the Depositor, each Receivable was secured by a valid, binding and enforceable
first priority perfected security interest in favor of the Seller in the related Financed Vehicle, which security interest has been validly assigned by the Seller to the Depositor. The Servicer has received, or will receive within 180 days
after the Closing Date, the original certificate of title for each Financed Vehicle (other than any Financed Vehicle that is subject to a certificate of title statute or motor vehicle registration law that does not require that the original
certificate of title for such Financed Vehicle be delivered to the Seller). 
 (g) Receivables in Force. No Receivable
has been satisfied, subordinated or rescinded, nor has any Financed Vehicle been released in whole or in part from the Lien granted by the related Receivable. 
 (h) No Waiver. No provision of any Receivable has been waived in such a manner that such Receivable fails to meet all of the representations and warranties made by the Depositor in this
Section 2.3 with respect thereto. 
 (i) No Defenses. No Receivable is subject to any right of rescission, setoff,
counterclaim or defense, including the defense of usury, and the operation of any of the terms of any Receivable, or the exercise of any right thereunder, will not render such Receivable unenforceable in whole or in part or subject to any right of

has no knowledge that any default, breach, violation or event permitting acceleration under the terms of any Receivable has occurred or that any continuing condition that with notice or the lapse of time or both would constitute a default, breach,
violation or event permitting acceleration under the terms of any Receivable has arisen, and the Depositor has not waived any such event or condition. 

  
 22 









 (l) Title. The Depositor has purchased the Receivables from the Seller. The Depositor
intends that the transfer of the Receivables contemplated by Section 2.1 constitute a sale of the Receivables from the Depositor to the Trust and that the beneficial interest in, and title to, the Receivables not be part of the Depositor’s
estate in the event of the filing of a bankruptcy petition by or against the Depositor under any bankruptcy law. The Depositor has not sold, transferred, assigned or pledged any Receivable to any Person other than the Trust. The Depositor has not
created, incurred or suffered to exist any Lien, encumbrance or security interest on any Receivable except for the Lien of the Indenture. 
 (m) Security Interest Matters. This Agreement creates a valid and continuing “security interest” (as defined in the Relevant UCC) in the Receivables in favor of the Trust, which security
interest is prior to all other Liens and is enforceable as such as against creditors of and purchasers from the Depositor. With respect to each Receivable, the Seller has taken all steps necessary to perfect its security interest against the related
Obligor in the related Financed Vehicle. The Receivables constitute “tangible chattel paper” (as defined in the Relevant UCC). The Depositor owns and has good and marketable title to the Receivables free and clear of any Lien, claim or
encumbrance of any Person. The Depositor has caused or will cause prior to the Closing Date the filing of all appropriate financing statements in the proper filing offices in the appropriate jurisdictions under applicable law necessary to perfect
the security interest in the Receivables granted to the Trust under this Agreement. Other than the security interest granted to the Trust under this Agreement, the Depositor has not pledged, assigned, sold, granted a security interest in or
otherwise conveyed any of the Receivables. The Depositor has not authorized the filing of and is not aware of any financing statements against the Depositor that include a description of collateral covering the Receivables other than any financing
statement relating to the security interest granted to the Trust under this Agreement or that has been terminated. The Depositor is not aware of any judgment or tax lien filings against the Depositor. The security interest of the Seller in each
Financed Vehicle has been validly assigned by the Depositor to the Trust. 
 (n) Financing Statements. All financing
statements filed or to be filed against the Depositor in favor of the Indenture Trustee (as assignee of the Trust) contain a statement substantially to the following effect: “A purchase of or security interest in any collateral described in
this financing statement will violate the rights of the Indenture Trustee.” 
 (o) Valid Assignment. No Receivable
has been originated in, or is subject to the laws of, any jurisdiction under which the sale, transfer, assignment and conveyance of such Receivable under the Receivables Purchase Agreement or this Agreement or the pledge of such Receivable under the
Indenture is unlawful, void or voidable or under which such Receivable would be rendered void or voidable as a result of any such sale, transfer, assignment, conveyance or pledge. The Depositor has not entered into any agreement with any account
debtor that prohibits, restricts or conditions the assignment of the Receivables. 
 (p) One Original. There is only one
original executed copy of each Receivable.

accordance with the Simple Interest Method.

damage insurance (which insurance shall not be force placed insurance) covering the related Financed Vehicle in accordance with the Seller’s normal requirements. 
 (bb) Fair Market Value. The Receivables Purchase Price represents the fair market value of the Receivables. 
 (cc) Custodial Agreements. Immediately prior to the transfer of the Receivables by the Seller to the Depositor, the Seller or an Affiliate of the Seller had possession of the Receivable Files and

imposed by this Agreement. 
 2.4 Repurchase by Depositor 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 or failure to be true of the representations and warranties set
forth in Section 2.3. If such breach or failure shall not have been cured by the close of business on the last day of the Collection Period which includes the 30th day after the date on which the Depositor becomes aware of, or receives written
notice from the Servicer, the Backup Servicer or the Owner Trustee of, such breach or failure, and such breach or failure materially and adversely affects the interest of the Trust in a Receivable, the Depositor shall repurchase such Receivable from
the Trust on the Distribution Date immediately following such Collection Period. In consideration of the repurchase of a Receivable hereunder, the Depositor shall remit the Purchase Amount of such Receivable in the manner specified in
Section 4.5. 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 or failure to be true of the representations and warranties set forth
in Section 2.3 shall be to require the Depositor to repurchase Receivables pursuant to this Section 2.4. Neither the Owner Trustee nor the Indenture Trustee shall have any duty to conduct an affirmative investigation as to the occurrence
of any condition requiring the repurchase of any Receivable pursuant to this Section 2.4 or the eligibility of any Receivable for purposes of this Agreement. 
 2.5 Custody of Receivable Files. To assure uniform quality in servicing the Receivables and to reduce administrative costs, the Trust, upon the execution and delivery of this Agreement, hereby
revocably appoints the Servicer as its agent, and the Servicer hereby accepts such appointment, to act as custodian on behalf of the Trust and the Indenture Trustee of the following documents or instruments, which are hereby constructively delivered
to the Indenture Trustee, as pledgee of the Trust pursuant to the Indenture with respect to each Receivable (collectively, a “Receivable File”):

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

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

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

 On the Closing Date, the Servicer shall deliver to the Backup Servicer, the Trust and the Indenture Trustee an Officer’s
Certificate confirming that the Servicer has received, on behalf of the Trust and the Indenture Trustee, all the documents and instruments necessary for the Servicer to act as the agent of the Trust and the Indenture Trustee for the purposes set
forth in this Section 2.5, including the documents referred to herein, and the Backup Servicer, the Trust, the Owner Trustee and the Indenture Trustee are hereby authorized to rely on such Officer’s Certificate. In addition, within 180
days after the Closing Date, the Servicer shall deliver to the Backup Servicer, the Trust and the Indenture Trustee an Officer’s Certificate certifying that the Servicer has received the original certificate of title for each Financed Vehicle
except each Financed Vehicle securing an outstanding Receivable for which the Servicer has not received the original certificate of title as shall be identified in such Officer’s Certificate (and indicating whether such Financed Vehicle is
subject to a certificate of title statute or motor vehicle registration law that requires that the original certificate of title for such Financed Vehicle be delivered to the Seller). 

2.6 Duties of Servicer as Custodian. 
 (a) Safekeeping. The Servicer, in its capacity as custodian, shall hold the Receivable Files for the benefit of the Trust and the Indenture Trustee and maintain such accurate and complete accounts,
records and computer systems pertaining to each Receivable File as shall enable the Servicer, the Backup Servicer and the Trust to comply with the terms and provisions of this Agreement and the Indenture Trustee to comply with the terms and
conditions of the Indenture. In performing its duties as custodian, the Servicer shall act with reasonable care, using that degree of skill and attention that the Servicer exercises with respect to the files relating to comparable motor vehicle
retail installment sale contracts that the Servicer services for itself or others. The Servicer shall conduct, or cause to be conducted, in accordance with its customary practices and procedures, periodic audits of the Receivable Files held by it

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

2.8 Indemnification by the Custodian. The Servicer, in its capacity as custodian, shall indemnify and hold harmless the Backup
Servicer, the Trust, the Owner Trustee and the Indenture Trustee and each of their respective officers, directors, employees and agents from and against any and all liabilities, obligations, losses, compensatory damages, payments, costs or expenses

as the result of any act or omission by the Servicer relating to the maintenance and custody of the Receivable Files; provided, however, that the Servicer shall not be liable hereunder to the Backup Servicer, the Owner Trustee or the Indenture
Trustee, as applicable, to the extent that such liabilities, obligations, losses, compensatory damages, payments, costs or expenses result from the willful misfeasance, bad faith or negligence of the Backup Servicer, the Owner Trustee or the
Indenture Trustee, as applicable.

 ARTICLE III 

ADMINISTRATION AND SERVICING OF RECEIVABLES AND OTHER TRUST PROPERTY 

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, 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 

  
 28 









 
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 and each data-map refresh referred to in clause (ii) above shall be at the cost of CarMax. 

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, in its sole discretion,
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 

  
 29 









 
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. 
 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. 
 3.4 Physical Damage Insurance. The Servicer shall follow its customary practices and procedures to determine whether or not each Obligor shall have maintained physical damage insurance covering the
related Financed Vehicle. 
 3.5 Maintenance of Security Interests in Financed Vehicles. The Servicer shall take such
steps, in accordance with the standard of care required under Section 3.1, as are necessary to maintain perfection of the security interest created by each Receivable in the related Financed Vehicle at all times. The Trust hereby authorizes the
Servicer, and the Servicer hereby agrees, to take such steps as are necessary to re-perfect such security interest on behalf of the Trust and the Indenture Trustee in the event the Servicer receives notice of, or otherwise has actual knowledge of,
the fact that such security interest is not perfected as a result of the relocation of a Financed Vehicle or for any other reason. The Servicer shall not release, in whole or in part, any security interest in a Financed Vehicle created by the
related Receivable except as permitted herein or in accordance with its customary standards, policies, practices and procedures. 
 3.6 Amendment of Receivable Terms. The Servicer shall not impair in any material respect the rights of the Depositor, the Trust, the Owner Trustee, the Indenture Trustee, the Certificateholders or
the Noteholders in the Receivables or, except as permitted under Section 3.2, otherwise amend or alter the terms of the Receivables if, as a result of such amendment or alteration, the interests of the Depositor, the Trust, the Owner Trustee,
the Indenture Trustee, the Certificateholders or the Noteholders hereunder would be materially adversely affected. 
 3.7
Purchase by Servicer upon Breach. The Depositor, the Servicer, the Backup Servicer or the Owner Trustee, as the case may be, shall inform the other parties to this 

  
 30 









 
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 purchase Receivables pursuant to this Section 3.7. Neither the Owner Trustee nor the Indenture Trustee shall have any duty to conduct an affirmative investigation as to the
occurrence of any condition requiring the purchase of any Receivable pursuant to this Section 3.7.

other amount as may be determined in accordance with Section 8.2(c). The Servicer shall pay all expenses incurred by it in connection with its activities hereunder (including the fees and expenses of the Owner Trustee and the Indenture Trustee,
including the reasonable fees and expenses of their attorneys, and any custodian appointed by the Owner Trustee and the Indenture Trustee, the fees and expenses of independent accountants, taxes imposed on the Servicer and expenses incurred in

Servicer shall deliver to the Depositor, the Backup Servicer, the Seller, the Owner Trustee, the Indenture Trustee and each Paying Agent, with a copy to the Rating Agencies, a certificate of a Servicing Officer substantially in the form of Exhibit A
(a “Servicer’s Certificate”) and attached to a Servicer’s report containing all information necessary to make the transfers and distributions pursuant to Sections 4.5, 4.6 and 4.7, together with the written statements to be
furnished by the Owner Trustee to the Certificateholders pursuant to Section 4.9 and by the Indenture Trustee to the Noteholders pursuant to Section 4.9 and pursuant to Section 6.6 of the Indenture. The Servicer shall separately
identify (by account number) in a written notice to the Depositor, the Backup Servicer, the Owner Trustee and the Indenture Trustee the Receivables to be repurchased by the Depositor or to be purchased by the Servicer, as the case may be, on the
Business Day preceding such Distribution Date, and, upon request of one of the foregoing parties, each Receivable which became a Defaulted Receivable during the related Collection Period. The Servicer shall deliver to the Rating Agencies any
information, to the extent it is available to the Servicer, that the Rating Agencies reasonably request (and the initial Servicer shall specify in writing to the successor Servicer any such requests that remain unsatisfied during the servicing
transition to the successor Servicer) in order to monitor the Trust.

Indenture Trustee, the Certificateholders or the Noteholders shall be required by applicable statutes, regulations or the provisions of any Transaction Document to have access to such documentation. Such access shall be afforded without charge, but
only upon reasonable request and during normal business hours at the offices of the Servicer. Nothing in this Section 3.12 shall affect the obligation of the Servicer and the Backup Servicer, as applicable, to observe any applicable law
prohibiting disclosure of information regarding the Obligors, and the failure of the Servicer to provide access to information as a result of such obligation shall not constitute a breach of this Section 3.12. Each Certificateholder or

Collection Account shall be held in trust for the benefit of the Noteholders and the Certificateholders. The Collection Account shall be under the sole dominion and control of the Indenture Trustee; provided, however, that the Servicer
may make deposits to and direct the Indenture Trustee in writing to make withdrawals from the Collection Account in accordance with this Agreement, the Indenture and the Trust Agreement. All monies deposited from time to time in the Collection

and conditions of the Transaction Documents. 
 If the Servicer is required to remit collections on a daily basis pursuant to
the first sentence of Section 4.2, all amounts held in the Collection Account shall, to the extent permitted by applicable law, rules and regulations, be invested, as directed in writing by the Servicer, by the bank or trust company then
maintaining the Collection Account in Permitted 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

writing to make withdrawals from the Note Payment Account in accordance with this Agreement and the Indenture. All monies deposited from time to time in the Note Payment Account pursuant to this Agreement and the Indenture shall be held by the
Indenture Trustee as part of the Trust Property and shall be applied as provided in this Agreement and the Indenture. The amounts on deposit in the Note Payment Account shall not be invested. If the Note Payment Account is no longer to be maintained
at the Indenture Trustee, the Servicer shall, with the Indenture Trustee’s assistance as necessary, promptly (and in any case within ten (10) calendar days or such longer period not to exceed thirty (30) calendar days as to which each
Rating Agency may consent) cause the Note Payment 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 number or location of the Note 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 with this Agreement
and the Trust Agreement. All monies deposited from time to time in the Certificate Payment Account pursuant to this Agreement and the Indenture shall be held by the Owner Trustee as part of the Trust Property and shall be applied as provided in this
Agreement and the Trust Agreement. The amounts on deposit in the Certificate Payment Account shall not be invested. If the Certificate Payment Account is no longer to be maintained at the Owner Trustee, the Servicer shall, with the Owner
Trustee’s assistance as necessary, promptly (and in any case within ten (10) calendar days or such longer period not to exceed thirty (30) calendar days as to which each Rating Agency may consent) cause the Certificate Payment Account
to be moved to an Eligible Institution. The Servicer shall promptly notify the Indenture Trustee and the Owner Trustee in writing of any change in the account number or location of the Certificate Payment Account.

sum of (i) the Note Balance as of the day preceding such Distribution Date, (ii) the Total Note Interest for each Class of Notes for such Distribution Date and (iii) the Total Servicing Fee for the preceding Collection Period and any

the related Receivable has been classified as a Defaulted Receivable) but excluding payments with respect to Purchased Receivables) as soon as practicable and in no event after the close of business on the second Business Day after such receipt;
provided, however, that for so long as (i) CarMax is the Servicer, (ii) no Event of Servicing Termination shall have occurred and be continuing and (iii) 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 Notes evidencing not less than 25% of the Note Balance of the Controlling Class or unless a Responsible Officer of the Owner Trustee or the Indenture Trustee, as applicable, has actual knowledge of such event or
circumstance. The Servicer shall remit to the Collection Account on the Closing Date all amounts received by the Servicer on or in respect of the Receivables (including Liquidation Proceeds and all amounts received by the Servicer in connection with
the repossession and sale of a Financed Vehicle (whether or not the related Receivable has been classified as a Defaulted Receivable)) during the period from but excluding the Cutoff Date to and including the second Business Day preceding the

 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 has been classified as a
Defaulted Receivable) but excluding payments with respect to Purchased Receivables) shall be applied by the Servicer, as of the last day of such Collection Period, to interest and principal on such Receivable in accordance with the Simple Interest
Method.

 4.4 Simple Interest Advances and Unreimbursed Servicer Advances. 

(a) If, as of the end of any Collection Period, one or more payments of Monthly P&I due under any Receivable (other than a Defaulted
Receivable) outstanding at the end of such Collection Period shall not have been received by the Servicer and remitted to the Collection Account pursuant to Section 4.2, the Servicer may, at its option, make, on the Business Day preceding the
Distribution Date immediately following such Collection Period, a Simple Interest Advance with respect to such Receivable by depositing in or crediting to the Collection Account the amount of Monthly P&I allocable to interest scheduled to have
been paid during such Collection Period, assuming that such Receivable was paid on its due date, minus the amount of Monthly P&I actually received and allocated to interest, if any, with respect to such Receivable during such Collection
Period. 
 (b) If the Servicer determines that it has made an Unreimbursed Servicer Advance, the Servicer shall reimburse itself
for such Unreimbursed Servicer Advance from unrelated amounts received by the Servicer on or in respect of the Receivables (including Liquidation Proceeds and all amounts received by the Servicer in connection with the repossession and sale of a
Financed Vehicle (whether or not the related Receivable has been classified as a Defaulted Receivable)); provided, however, that the Servicer shall furnish to the Indenture Trustee and the Owner Trustee, on or before the Distribution
Date following the Collection Period during which such reimbursement is taken, a certificate of a Servicing Officer setting forth the basis for such determination, the amount of such Unreimbursed Servicer Advance, the Receivable with respect to

the Reserve Account in Permitted Investments that mature not later than the Business Day preceding the next Distribution Date. All such Permitted Investments shall be held to maturity. On any Distribution Date, all interest and other income (net of
losses and investment expenses) on funds on deposit in the Reserve Account, to the extent that funds on deposit therein, as certified by the Servicer, exceed the Required Reserve Account Amount, shall, at the written direction of the Servicer,

Account to be moved to an Eligible Institution. The Servicer shall promptly notify the Indenture Trustee and the Owner Trustee in writing of any change in the account number or location of the
Reserve Account. 
 (c) With respect to any Reserve Account Property: 

(i) any Reserve Account Property that is a “financial asset” (as defined in Section 8-102(a)(9) of the
Relevant UCC) shall be physically delivered to, or credited to an account in the name of, the Eligible Institution maintaining the Reserve Account, in accordance with such institution’s customary procedures such that such institution
establishes a “securities entitlement” in favor of the Indenture Trustee with respect thereto; 
 (ii)
any Reserve Account Property that is held in deposit accounts shall be held solely in the name of the Indenture Trustee at one or more depository institutions having the Required Rating and each such deposit account shall be subject to the exclusive
custody and control of the Indenture Trustee and the Indenture Trustee shall have sole signature authority with respect thereto; and 
 (iii) except for any deposit accounts specified in clause (ii) above, the Reserve Account shall only be invested in securities or in other assets which the Eligible Institution maintaining the
Reserve Account agrees to treat as “financial assets” (as defined in Section 8-102(a)(9) of the Relevant UCC). 

(d) If the Reserve Account Amount for any Distribution Date (after giving effect to the withdrawal of the Reserve Account Draw Amount for
such Distribution Date) exceeds the Required Reserve Account Amount for such Distribution Date, the Servicer shall instruct the Indenture Trustee in writing to distribute the amount of such excess (i) first, to the Note Payment Account, for
payment of principal of the Notes in the priority set forth in Section 2.8(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)(xiii) or (xiv) 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
the Owner Trustee hereby release, on each Distribution Date, their security interest in, to and under Reserve Account Property distributed to the Certificateholders. 
 (e) If the Note Balance, and all other amounts owing or to be distributed hereunder or under the Indenture or the Trust Agreement to the Noteholders or the Certificateholders, have been paid in full and

Backup Servicer, to the extent not paid by the Servicer, shall be paid solely from the application of Available Funds pursuant to Section 2.8(a)(ii) and (xiv) or Section 5.4(b)(ii) of the Indenture, as applicable. 

7.4 Merger or Consolidation of, or Assumption of the Obligations of, Servicer or Backup Servicer. 

(a) Any Person (i) into which the Servicer shall be merged or consolidated, (ii) resulting from any merger, conversion or
consolidation to which the Servicer shall be a party or (iii) that shall succeed by purchase and assumption to all or substantially all of the business of the Servicer, which Person in any of the foregoing cases is an Eligible Servicer and
executes an agreement of assumption to perform every obligation of the Servicer under this Agreement, shall be the successor to the Servicer under this Agreement without the execution or filing of any other document or any further act on the part of
any of the parties to this Agreement; provided, however, that (x) the Servicer shall have delivered to the Depositor, the Backup Servicer, the Owner Trustee and the Indenture Trustee an Officer’s Certificate and an Opinion of
Counsel each stating that such merger, conversion, consolidation or succession and such agreement of assumption comply with this Section 7.4 and (y) the Servicer shall have delivered to the Depositor, the Backup Servicer, the Owner Trustee
and the Indenture Trustee an Opinion of Counsel either (A) stating that, in the opinion of such counsel, all financing statements and continuation statements and amendments thereto have been authorized and filed that are necessary to fully
preserve and protect the interest of the Trust and the Indenture Trustee, respectively, in the Receivables, and reciting the details of such filings or referring to prior Opinions of Counsel in which such details are given, or (B) stating that,
in the opinion of such counsel, no such action shall be necessary to fully preserve and protect such interest. The Servicer shall provide prior written notice of any merger, conversion, consolidation or succession pursuant to this Section 7.4
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

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.

 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. 

  
 54 









 (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. 
 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. 
 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 (b), the Backup Servicer may petition a court for its removal.

 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 

  
 55 









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

ARTICLE VIII 

SERVICING TERMINATION 
 8.1 Events of Servicing Termination. 
 (a) The occurrence of any one of the
following events shall constitute an event of servicing termination hereunder (each, an “Event of Servicing Termination”): 
 (i) any failure by the Servicer to deliver to the 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 

  
 56 









 (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 Administrator, 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 (a) prior to the continuance of such event through the end of any cure period specified in Section (a). 

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


  
 57 









 
all respects to the outgoing Servicer in its capacity as Servicer under this Agreement and shall be subject to all the obligations and duties placed on the Servicer by the terms and provisions of
this Agreement; provided, however, that the 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 (xiii) or Section 5.4(b)(ii) of the Indenture, as
applicable. 
 (c) If the Backup Servicer is appointed successor Servicer pursuant to Section (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 (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 

  
 58 









 
appointed successor Servicer pursuant to Section (a) because the Backup 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 (xiii) of the Indenture, as applicable. 

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 

  
 59 









 
reasonable request and during normal business hours at the offices of the successor Servicer. Nothing in this Section 8.3 shall affect the obligation of the successor Servicer to observe any
applicable law prohibiting disclosure of information regarding the Obligors, and the failure of the Servicer to provide access to information as a result of such obligation shall not constitute a breach of this Section 8.3. 

(d) Any transfer of servicing hereunder shall not constitute an assumption by the related successor Servicer of any liability of the
related outgoing Servicer arising out of any breach by such outgoing Servicer of such outgoing Servicer’s duties hereunder prior to such transfer of servicing. 
 8.4 Notification to Noteholders, Certificateholders and Rating Agencies. Upon any notice of an Event of Servicing Termination or upon any termination of, or any appointment of a successor to, the
Servicer pursuant to this Article VIII, the Indenture Trustee shall give prompt written notice thereof to the Noteholders and the Owner Trustee shall give prompt written notice thereof to the Certificateholders, the Administrator and the Depositor
(who shall promptly give such notice to the Rating Agencies). 
 8.5 Waiver of Past Events of Servicing Termination. The
Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class may, on behalf of all Noteholders, waive any Event of Servicing Termination and its consequences, except an event resulting from the failure to make any
required deposits to or payments from the Collection Account, the Note Payment Account, the Certificate Payment Account or the Reserve Account in accordance with this Agreement. Upon any such waiver of an Event of Servicing Termination, such event
shall cease to exist, and shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other event or impair any right arising therefrom, except to the extent expressly so waived.

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

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 

  
 60 









 
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 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 (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

federal income taxation of any Notes Outstanding or any Noteholder and (y) that no such amendment may:

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
