(d) Each Note shall be dated the date of its authentication. The Notes shall be issuable as registered Notes in minimum denominations of

 (e) No Note shall be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein executed by the Indenture Trustee by the manual signature of one of its authorized signatories, and such certificate upon
any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder. 

Section 2.3 Temporary Notes. 

(a) Pending the preparation of Definitive Notes pursuant to Section 2.13, the Issuer may execute, and upon receipt of an Issuer Order the
Indenture Trustee shall authenticate and deliver, temporary Notes that are printed, lithographed, typewritten, mimeographed or otherwise produced of the tenor of the Definitive Notes in lieu of which they are issued and with such variations not
inconsistent with the terms of this Indenture as the officers executing such Notes may determine, as evidenced by their execution of such Notes. 

(b) If temporary Notes are issued pursuant to Section 2.3(a), the Issuer shall cause Definitive Notes to be prepared without unreasonable
delay. After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at the office or agency of the Note Registrar to be maintained as provided in Section 3.2,
without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuer shall execute, and the Indenture Trustee shall authenticate and deliver in exchange therefor, a like principal amount of Definitive Notes of
authorized denominations. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as Definitive Notes. 

Section 2.4 Tax Treatment. 

(a) The Issuer has entered into this Indenture, and the Notes shall be issued, with the intention that, for federal, State and local income
and franchise tax purposes, the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) shall qualify as indebtedness of the Issuer secured by the Trust Estate.
The Issuer, by entering into this Indenture, and each Noteholder, by its acceptance of a Note (and each Note Owner by its acceptance of an interest in the applicable Book-Entry Note), agree to treat the Notes (other than any Retained Notes held by
the Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) as indebtedness of the Issuer for federal, State and local income and franchise tax purposes. 

(b) Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, agrees to
provide to the Indenture Trustee, any Paying Agent or the Issuer, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the Noteholder FATCA Information. 

(c) Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, agrees that
the Indenture Trustee has the right to withhold any amounts of interest (properly withholdable under law and without any corresponding gross-up) payable to a Noteholder or holder of an interest in a Note that
fails to comply with the requirements of Section 2.4(b).

 Section 2.5 Registration; Registration of Transfer and Exchange. 

(a) The Indenture Trustee initially shall be the registrar (the “Note Registrar”) for the purpose of registering Notes and
transfers of Notes as herein provided. The Note Registrar shall cause to be kept a register (the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Note Registrar shall provide for the
registration of Notes and the registration of transfers of Notes. Upon any resignation of any Note Registrar, the Issuer shall promptly appoint a successor or, if it elects not to make such an appointment, assume the duties of Note Registrar. 

(b) If a Person other than the Indenture Trustee is appointed by the Issuer as Note Registrar, (i) the Issuer shall give the Indenture
Trustee prompt written notice of the appointment of such Note Registrar and of the location, or any change in the location, of the Note Register, (ii) the Indenture Trustee shall have the right to inspect the Note Register at all reasonable
times and to obtain copies thereof and (iii) the Indenture Trustee shall have the right to rely upon a certificate executed on behalf of the Note Registrar by an Executive Officer thereof as to the names and addresses of the Holders of the
Notes and the principal amounts and number of such Notes. 
 (c) Upon surrender for registration of transfer of any Note at the office or
agency of the Issuer to be maintained as provided in Section 3.2, if the requirements of Section 8-401 or 8A-401, as applicable, of the Relevant UCC are met,
the Issuer shall execute, and the Indenture Trustee shall authenticate and deliver to the Noteholder making such surrender, in the name of the designated transferee or transferees, one or more new Notes of the same Class in any authorized
denomination, of a like aggregate principal amount. The Indenture Trustee may rely upon the Administrator with respect to the determination of whether the requirements of Section 8-401 or 8A-401, as applicable, of the Relevant UCC are met. 
 (d) At the option of the Noteholder, Notes may be
exchanged for other Notes of the same Class in any authorized denominations, of a like aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, if the
requirements of Section 8-401 or 8A-401, as applicable, of the Relevant UCC are met, the Issuer shall execute, and the Indenture Trustee shall authenticate and
deliver to the Noteholder making such exchange, the Notes which such Noteholder is entitled to receive. The Indenture Trustee may rely upon the Administrator with respect to the determination of whether the requirements of Section 8-401 or 8A-401, as applicable, of the Relevant UCC are met. 

(e) All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Issuer, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 

  
 6 













 (f) All Notes presented or surrendered for registration of transfer or exchange shall be
duly endorsed by, or be accompanied by a written instrument of transfer in form satisfactory to the Indenture Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing, with such signature guaranteed by
an “eligible guarantor institution” meeting the requirements of the Note Registrar. 
 (g) No service charge shall be made to a
Holder for any registration of transfer or exchange of Notes, but the Indenture Trustee may require payment by such Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of
transfer or exchange of Notes, other than exchanges pursuant to Section 2.3 or Section 9.6 not involving any transfer. 
 (h) The
Issuer shall not be required to make, and the Note Registrar need not register, transfers or exchanges of Notes selected for redemption or Notes with respect to which the due date for any payment will occur within fifteen (15) days. 

(i) Each Person who initially acquires a Note (or an interest therein) or to whom a Note (or an interest therein) is transferred (and its
fiduciary, if applicable) will be deemed to have represented and warranted, by its acceptance of such Note (or an interest therein), that either (a) it is not acquiring such Note (or an interest therein) with the plan assets of either
(1) a Benefit Plan Investor or (2) an employee benefit plan or arrangement not subject to Title I of ERISA or Section 4975 of the Code; or (b) the acquisition and holding of such Note (or an interest therein) will not give rise
to a non-exempt “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code or a violation of any Similar Law. 

(j) Any purported transfer of a Note not in accordance with this Section 2.5 shall be null and void and shall not be given effect for any
purpose whatsoever. 
 Section 2.6 Mutilated, Destroyed, Lost or Stolen Notes. 

(a) If (i) any mutilated Note is surrendered to the Indenture Trustee, or the Indenture Trustee receives evidence to its satisfaction of
the destruction, loss or theft of any Note, and (ii) there is delivered to the Indenture Trustee such security or indemnity as may be required by it to hold the Issuer and the Indenture Trustee harmless, then, in the absence of notice to the
Issuer, the Note Registrar or the Indenture Trustee that such Note has been acquired by a “protected purchaser” (as defined in the Relevant UCC), and provided that the requirements of
Section 8-405 or 8A-405, as applicable, of the Relevant UCC are met, the Issuer shall execute and the Indenture Trustee shall authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Note, a replacement Note of the same Class; provided, however, that if any such destroyed, lost or stolen Note, but not a mutilated Note, shall have become or within seven
(7) days of the Indenture Trustee’s receipt of evidence to its satisfaction of such destruction, loss or theft shall be due and payable, or shall have been called for redemption in whole pursuant to Section 10.1, instead of issuing a
replacement Note of the same Class, the Issuer may pay such destroyed, lost or stolen Note when so due or payable or upon the Redemption Date without surrender thereof. The Indenture Trustee may conclusively rely upon the Administrator with respect
to the determination of whether the requirements of Section 8-405 or 8A-405, as applicable, of the Relevant UCC are met. If, after the delivery of such replacement
Note or payment of a destroyed, lost or stolen Note pursuant to the proviso to the preceding sentence, a “protected purchaser” (as defined in the Relevant UCC) of the original Note in lieu of which such


  
 7 













 
replacement Note was issued presents for payment such original Note, the Issuer and the Indenture Trustee shall be entitled to recover such replacement Note (or such payment) from the Person to
whom such replacement Note was delivered or any Person taking such replacement Note from such Person to whom such replacement Note was delivered or any assignee of such Person, except a “protected purchaser” (as defined in the Relevant
UCC), and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Issuer or the Indenture Trustee in connection therewith. 

(b) Upon the issuance of any replacement Note under this Section 2.6, the Issuer may require the payment by the Holder of such Note of a
sum sufficient to cover any tax or other governmental charge that may be imposed in connection with such issuance and any other reasonable expenses (including the fees and expenses of the Indenture Trustee) related thereto. 

(c) Every replacement Note issued pursuant to this Section 2.6 in replacement of any mutilated, destroyed, lost or stolen Note shall
constitute an original additional contractual obligation of the Issuer, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder. 
 (d) The provisions of this Section 2.6 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 

Section 2.7 Persons Deemed Owners. Prior to due presentation of a Note for registration of transfer, the Issuer, the Indenture
Trustee and any agent of the Issuer or the Indenture Trustee may, subject to Section 2.6, treat the Person in whose name such Note is registered in the Note Register (as of the day of determination) as the owner of such Note for the purpose of
receiving payments of principal of and interest on such Note and for all other purposes whatsoever, whether or not such Note shall be overdue, and none of the Issuer, the Indenture Trustee or any agent of the Issuer or the Indenture Trustee shall be
affected by any notice to the contrary.

Section 10.1(a) or Section 10.2(b) shall, if surrendered to any Person other than the Indenture Trustee, be delivered to the Indenture Trustee and shall be promptly canceled by the Indenture Trustee. The Issuer may at any time deliver to
the Indenture Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Issuer may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly canceled by the Indenture Trustee. No Notes
shall be authenticated in lieu of or in exchange for any Notes canceled as provided in this Section 2.9, except as expressly permitted by this Indenture. All canceled Notes may be held or disposed of by the Indenture Trustee in accordance with
its standard retention or disposal policy as in effect at the time unless the Issuer shall direct by an Issuer Order that they be destroyed or returned to it, provided that such Issuer Order is timely and the Notes have not been previously disposed
of by the Indenture Trustee.

Issuer’s Certificate, an Opinion of Counsel and Independent Certificates in accordance with TIA Sections 314(c) and 314(d)(1) or an Opinion of Counsel in lieu of such Independent Certificates to the effect that the TIA does not require any such
Independent Certificates. If the Commission shall issue an exemptive order under TIA Section 304(d) modifying the Indenture Trustee’s obligations under TIA Sections 314(c) and 314(d)(1), the Indenture Trustee shall release property from

Book-Entry Notes. The Notes (other than any Retained Notes), upon original issuance, shall be issued in the form of typewritten Notes representing Book-Entry Notes, to be delivered to The Depository Trust Company, the initial Clearing Agency,
by, or on behalf of, the Issuer. The Book-Entry Notes shall be such Notes registered initially or from time to time on the Note Register in the name of Cede & Co., the nominee of the initial Clearing Agency, and no Note Owner thereof shall
receive a definitive Note representing such Note Owner’s interest in such Note, except as provided in Section 2.13. Unless and until definitive, fully registered Notes (the “Definitive Notes”) have been issued to such Note
Owners pursuant to Section 2.13: 
  

	 	(i)	 the provisions of this Section 2.11 shall be in full force and effect;

purposes of this Indenture (including the payment of principal of and interest on the Notes and the giving of instructions or directions hereunder) as the sole Holder of the Notes, and shall have no obligation to the Note Owners;

 14 














	 	(v)	 whenever this Indenture requires or permits actions to be taken based upon written instructions or directions
of Holders of Notes (or Holders of Notes of any Class thereof, including the Controlling Class) evidencing a specified percentage of the principal amount of the Notes or any Class of Notes Outstanding, the Clearing Agency shall be deemed
to represent such percentage only to the extent that it has received instructions to such effect from Note Owners and/or Clearing Agency Participants owning or representing, respectively, such required percentage of the beneficial interest in the
Notes or such Class of Notes and has delivered such instructions to the Indenture Trustee. 


 Section 2.12
Notices to Clearing Agency. Whenever a notice or other communication to the Noteholders is required under this Indenture, unless and until Definitive Notes shall have been issued to such Note Owners pursuant to Section 2.13, the
Indenture Trustee shall give all such notices and communications specified herein to be given to Holders of the Notes to the Clearing Agency, and shall have no obligation to such Note Owners. 

Section 2.13 Definitive Notes. The Retained Notes, upon original issuance, will be in the form of Definitive Notes, but, at the
request of all of the holders thereof, may be exchanged for Book-Entry Notes. If (i) the Administrator or the Servicer advises the Indenture Trustee in writing that the Clearing Agency is no longer willing or able to properly discharge its
responsibilities with respect to the Book-Entry Notes and the Indenture Trustee or the Administrator is unable to locate a qualified successor or (ii) after the occurrence of an Event of Default or an Event of Servicing Termination, Note Owners
of the Book-Entry Notes representing beneficial interests aggregating not less than 51% of the principal amount of such Notes advise the Indenture Trustee and the Clearing Agency in writing that the continuation of a book-entry system through the
Clearing Agency is no longer in the best interests of such Note Owners, then the Clearing Agency shall notify all Note Owners and the Indenture Trustee in writing of the occurrence of such event and of the availability of Definitive Notes to Note
Owners requesting the same. Upon surrender to the Indenture Trustee of the typewritten Notes representing the Book-Entry Notes by the Clearing Agency, accompanied by registration instructions, the Issuer, at its own expense, shall execute and
deliver the Definitive Notes to the Indenture Trustee and the Indenture Trustee shall authenticate the Definitive Notes in accordance with the instructions of the Clearing Agency. None of the Issuer, the Note Registrar or the Indenture Trustee shall
be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Notes, the Indenture Trustee shall recognize the Holders of the
Definitive Notes as Noteholders. 
 Section 2.14 Authenticating Agents. 

(a) The Indenture Trustee may appoint one or more Persons (each, an “Authenticating Agent”) with power to act on its behalf
and subject to its direction in the authentication of Notes in connection with issuance, transfers and exchanges under Section 2.2, Section 2.3, Section 2.5 and Section 2.6, as fully to all intents and purposes as though each
such Authenticating Agent had been expressly authorized by those Sections to authenticate such Notes. For all purposes of this Indenture, the authentication of Notes by an Authenticating Agent pursuant to this Section 2.14 shall be deemed to be
the authentication of Notes “by the Indenture Trustee”. 

  
 15 













 (b) Any entity into which any Authenticating Agent may be merged or converted or with which
it may be consolidated, or any entity resulting from any merger, consolidation or conversion to which any Authenticating Agent shall be a party, or any entity succeeding to all or substantially all of the corporate trust business of any
Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, without the execution or filing of any document or any further act on the part of the parties hereto or such Authenticating Agent or such successor entity. 

(c) Any Authenticating Agent may at any time resign by giving written notice of resignation to the Indenture Trustee and the Owner Trustee.
The Indenture Trustee may at any time terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and the Owner Trustee. Upon receiving such notice of resignation or upon such a termination,
the Indenture Trustee may appoint a successor Authenticating Agent and shall give written notice of any such appointment to the Owner Trustee. 

(d) The Administrator agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services. The provisions of
Section 2.9 and Section 6.4 shall be applicable to any Authenticating Agent. 
 Section 2.15 Retained Notes. 

(a) As of the date of this Indenture, the Retained Notes have not been registered under the Securities Act and will not be listed on any
exchange. Unless and until such Notes have been sold pursuant to a transaction registered under the Securities Act, no transfer of such a Note shall be made unless such transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the registration requirements under the Securities Act and such state securities laws. Except in a transfer pursuant to Rule 144A or a transfer to the Depositor (or any other
entity whose separate existence from the Trust is disregarded for federal income tax purposes) or by the Depositor (or any other entity whose separate existence from the Trust is disregarded for federal income tax purposes) to an Affiliate thereof,
in the event that a transfer is to be made in reliance upon an exemption from the Securities Act and state securities laws, in order to assure compliance with the Securities Act and such laws, the Noteholder desiring to effect such transfer and such
Noteholder’s prospective transferee shall each certify to the Trust, the Indenture Trustee and the Depositor in writing the facts surrounding the transfer in substantially the forms set forth in Exhibit F (the “Transferor
Certificate”) and Exhibit G (the “Investment Letter”), in each case, with such revisions or modifications as may be determined by the Depositor. Except in a transfer pursuant to Rule 144A or a transfer to the Depositor or by the
Depositor (or any other entity whose separate existence from the Trust is disregarded for federal income tax purposes) to an Affiliate thereof, there shall also be delivered to the Depositor and the Indenture Trustee an Opinion of Counsel that such
transfer may be made pursuant to an exemption from the Securities Act, which opinion of counsel shall not be an expense of the Depositor, the Trust, the Owner Trustee or the Indenture Trustee (unless it is the transferee from whom such opinion is to
be obtained). The Trust shall cause the Depositor to provide to any Noteholder and any prospective transferee designated by any such Noteholder information regarding the Retained Notes and the Receivables and such other information as shall be
necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such Retained Notes without registration thereof under the Securities Act pursuant to the registration exemption


  
 16 













 
provided by Rule 144A. Each Noteholder desiring to effect such a transfer shall, and does hereby agree to, indemnify the Issuing Entity, the Owner Trustee, the Indenture Trustee, the Depositor
and CarMax (in any capacity) against any liability that may result if the transfer is not so exempt or is not made in accordance with federal and state securities laws. 

(b) (i) Sale, pledge or transfer of a Retained Note may only be made to a Person who is a United States person (within the meaning of
Section 7701(a)(30) of the Code); and (ii) no sale, pledge, or transfer of a Retained Note shall be made (x) to any one person in an amount less than $2,000,000 (or such other amount as the Depositor may determine in order to prevent
the Trust from being treated as a “publicly traded partnership” under Section 7704 of the Code) or (y) to a Special Pass-Through Entity, in each case under this clause (ii), unless (A) an opinion of counsel
satisfactory to the Indenture Trustee and the Depositor that such sale, pledge, or transfer shall not cause the Trust to be treated as an association (or publicly traded partnership) taxable as a corporation for federal income tax purposes shall
have been delivered to the Indenture Trustee and the Depositor and (B) the Depositor shall have provided prior written approval; provided, however, that the restrictions in Section 2.15(b)(i) and
(ii) above shall not continue to apply to such Retained Notes (covered by the opinion described in this clause) in the event counsel satisfactory to the Indenture Trustee and the Depositor has rendered an opinion, with respect to the
sale, pledge or transfer by the Depositor or an Affiliate thereof, to the effect that the Retained Notes to be sold, pledged, or transferred will be characterized as indebtedness for federal income tax purposes. Any transferee, other than the
Depositor or any other entity whose separate existence from the Trust is disregarded for federal income tax purposes, acquiring a Retained Note or an interest therein shall be deemed to have made the representations set forth in
Section 2.4 (as if Section 2.4(a) applied to the Retained Notes). Any attempted sale, pledge or other transfer in contravention of this Section 2.15(b) will be void ab
initio and the purported transferor will continue to be treated as the owner of the Retained Note. For the purposes of this Section 2.15(b), “Special Pass-Through Entity” means a grantor trust, S corporation, or
partnership (as determined, in each case, for Federal income tax purposes) where more than 50% of the value of any beneficial owner’s interest in such pass through entity is attributable to the pass-through entity’s interest in the
Retained Note. 
 (c) By directly or indirectly acquiring a Retained Note in a transaction pursuant to Rule 144A, each initial purchaser,
transferee and owner of a beneficial interest will be deemed to represent, warrant and agree as follows: 
  

	 	(i)	 it understands that such Notes have not been registered under the Securities Act, and may not be sold except as
permitted in the following sentence. It understands and agrees, on its own behalf and on behalf of any accounts for which it is acting as hereinafter stated, (x) that such Notes are being offered only in a transaction not involving any public
offering within the meaning of the Securities Act and (y) that such Notes may be resold, pledged or transferred only (i) to the Depositor, (ii) to an “accredited investor” as defined in Rule 501(a)(1),(2),(3) or (7) of
Regulation D under the Securities Act (an “Accredited Investor”) acting for its own account (and not for the account of others) or as a fiduciary or agent for others (which others also are Accredited Investors unless the holder is a
bank 



  
 17 














	 	
acting in its fiduciary capacity) that executes a certificate substantially in the form of the Investment Letter, (iii) so long as such Note is eligible for resale pursuant to Rule 144A
under the Securities Act, to a person whom it reasonably believes after due inquiry is a “qualified institutional buyer” as defined in Rule 144A, acting for its own account (and not for the account of others) or as a fiduciary or agent for
others (which others also are “qualified institutional buyers”) to whom notice is given that the resale, pledge or transfer is being made in reliance on Rule 144A or (iv) in a sale, pledge or other transfer made in a transaction
otherwise exempt from the registration requirements of the Securities Act, in which case the Indenture Trustee shall require that both the prospective transferor and the prospective transferee certify to the Indenture Trustee and the Depositor in
writing the facts surrounding such transfer, which certification shall be in form and substance satisfactory to the Indenture Trustee and the Depositor. Except in the case of a transfer described in clauses
(i) or (iii) above, the Indenture Trustee shall require that a written opinion of counsel (which will not be at the expense of the Depositor, any Affiliate of the Depositor or the Indenture Trustee), satisfactory to the
Indenture Trustee and the Depositor, be delivered to the Indenture Trustee and the Depositor to the effect that such transfer will not violate the Securities Act, and will be effected in accordance with any applicable securities laws of each state
of the United States. It will notify any purchaser of such Notes from it of the above resale restrictions, if then applicable. It further understands that in connection with any transfer of such Notes by it that the Indenture Trustee and the
Depositor may request, and if so requested it will furnish, such certificates and other information as they may reasonably require to confirm that any such transfer complies with the foregoing restrictions; 


 

	 	(ii)	 it is a “qualified institutional buyer” as defined under Rule 144A under the Securities Act and is
acquiring such Notes for its own account (and not for the account of others) or as a fiduciary or agent for others (which others also are “qualified institutional buyers”). It is familiar with Rule 144A under the Securities Act and is
aware that the seller of such Notes and other parties intend to rely on the foregoing representations, warranties and acknowledgements and the exemption from the registration requirements of the Securities Act provided by Rule
144A;


  

	 	(iii)	 it understands that Trust, the Indenture Trustee, the Depositor and others will rely upon the truth and
accuracy of the foregoing acknowledgments, representations and agreements, and it agrees that if any of the acknowledgments, representations and warranties deemed to have been made by it by its purchase of such Notes, for its own account or for one
or more accounts as to each of which it exercises sole investment discretion, are no longer accurate, it shall promptly notify the Depositor; and 



  
 18 














	 	(iv)	 the Trust, the Indenture Trustee and the Depositor are entitled to rely upon the foregoing representations,
warranties and acknowledgements and are irrevocably authorized to produce the foregoing representations, warranties and acknowledgments or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with
respect to the matters covered hereby. 


 (d) Any transfer in violation of this Section 2.15
will be of no force and effect, will be void ab initio, and will not operate to transfer any rights to the transferee, notwithstanding any instructions to the contrary to the Trust, the Indenture Trustee, or any intermediary. The Trust (or any other
entity whose separate existence from the Trust is disregarded for federal income tax purposes) may sell any Retained Notes acquired in violation of this Section 2.15 at the cost and risk of the purported owner. If at any
time the Trust determines or is notified that the Noteholder or Note Owner, as the case may be, was in breach, at the time given, of any of the representations set forth in this Section 2.15, the Trust may consider the
acquisition of such Retained Note or such beneficial interest in such Retained Note void and require that such Retained Note or such beneficial interest therein be transferred to a person designated by the Trust. If the transferee fails to transfer
such Retained Note or such beneficial interests in such Retained Note within thirty (30) days after notice of the voided transfer, then the Trust shall cause such Noteholder’s interest or Note Owner’s interest in such Retained Note to
be transferred in a commercially reasonable sale arranged by the Trust (conducted by the Trust or an agent of the Trust in accordance with Section 9-610(b) of the UCC as applied to securities that are
sold on a recognized market or that may decline speedily in value), subject to satisfaction of the requirements set forth in this Section 2.15. 

(e) During the period described in 17 CFR Part 246.12(f)(1), no Noteholder or Note Owner holding any Notes in satisfaction of CarMax’s
obligations under 17 CFR Part 246 may transfer any such Note (or interest therein) until the expiration of such period; provided, that, during such period, such Noteholder or Note Owner may transfer any such Note (or interest therein) to
CarMax or any “majority-owned affiliate” (as such term is defined in 17 CFR Part 246.2) of CarMax in accordance with the restrictions contained in 17 CFR Part 246.12. Any purported transfer of any such Note not in accordance with this
Section 2.15(e) shall be null and void and shall not be given effect for any purpose whatsoever. 
 (f) Upon any
sale or transfer of any Retained Note (or interest therein) as of the Closing Date, if for tax or other reasons it may be necessary to track any such Note (e.g., if the Notes have original issue discount), tracking conditions such as requiring
separate CUSIPs or that such Notes be in definitive registered form may be required by the Depositor or the Administrator as a condition to such transfer and the Trust shall cause the Administrator to provide prior written notice of such sale or
transfer and tracking condition to the Indenture Trustee.

 ARTICLE III COVENANTS 

Section 3.1 Payment of Principal and Interest; Determination of SOFR; Benchmark Replacement. 

(a) The Issuer shall duly and punctually pay the principal of and interest, if any, on the Notes in accordance with the terms of the Notes and
this Indenture. Amounts properly withheld under the Code by any Person from a payment to any Noteholder of interest and/or principal shall be considered as having been paid by the Issuer to such Noteholder for all purposes of this Indenture. 

(b) Wilmington Trust, National Association initially shall be the “Calculation Agent” for the purpose of identifying SOFR and
calculating the SOFR Rate pursuant to this Section 3.1. Upon any resignation of the Calculation Agent, the Administrator shall promptly appoint a successor or, if it elects not to make such an appointment, assume the duties
of Calculation Agent. If a Person other than Wilmington Trust, National Association is appointed by the Administrator as the Calculation Agent, the Administrator will give the Indenture Trustee prompt written notice of the appointment of the
Calculation Agent. 
 (c) So long as the Class A-2b Notes are Outstanding, the Calculation
Agent shall obtain SOFR in accordance with the definition of “SOFR Rate” on each SOFR Adjustment Date and shall promptly provide such rate to the Administrator or such person as directed by the Administrator. All determinations of SOFR by
the Calculation Agent, in the absence of manifest error, will be conclusive and binding on the Noteholders. 
 (d) If the Administrator
determines prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the determination of the then-current Benchmark, the Benchmark Replacement determined by the
Administrator will replace the then-current Benchmark for all purposes relating to the Class A-2b Notes in respect of such determination on such date and all such determinations on all subsequent dates.
The Administrator shall deliver written notice to each Rating Agency and the Calculation Agent on any SOFR Adjustment Date if, as of the applicable Reference Time, the Administrator has determined with respect to the related Accrual Period that
there will be a change in the SOFR Rate or the terms related thereto since the immediately preceding SOFR Adjustment Date due to a determination by the Administrator that a Benchmark Transition Event and its related Benchmark Replacement Date have
occurred. The Administrator shall have the right to make SOFR Conforming Changes and, in connection with the implementation of a Benchmark Replacement, Benchmark Replacement Conforming Changes, from time to time. 

(e) All percentages resulting from any calculation on the Class A-2b Notes shall be rounded to
the nearest one hundred-thousandth of a percentage point, with five-millionths of a percentage point rounded upwards (e.g., 9.8765445% (or 0.098765445) would be rounded to 9.87655% (or 0.0987655)), and all dollar amounts used in or resulting from
that calculation on the Class A-2b Notes will be rounded to the nearest cent (with one-half cent being rounded upwards). 

  
 20 













 (f) Any determination, decision or election that may be made by the Administrator or any
other Person in connection with a Benchmark Transition Event, a Benchmark Replacement Conforming Change or a Benchmark Replacement pursuant to this Section 3.1 (or pursuant to any capitalized term used in this Section 3.1 or in any such
capitalized term), including any determination with respect to administrative feasibility (whether due to technical, administrative or operational issues), a tenor, rate or adjustment or of the occurrence or
non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error, may be made in the
Administrator’s sole discretion, and, notwithstanding anything to the contrary in the Transaction Documents, will become effective without the consent of any other Person (including any Noteholder). The
Class A-2b Noteholders shall not have any right to approve or disapprove of these changes and shall be deemed by their acceptance of a Note to have agreed to waive and release any and all claims relating
to any such determinations. Notwithstanding anything to the contrary in the Transaction Documents, none of the Issuer, the Owner Trustee, the Indenture Trustee, the Administrator, the Calculation Agent, the Paying Agent, the Seller, the Depositor or
the Servicer will have any liability for any action or inaction taken or refrained from being taken by it with respect to any Benchmark, Benchmark Transition Event, Benchmark Replacement Date, Benchmark Replacement, Benchmark Replacement Adjustment,
Benchmark Replacement Conforming Changes or any other matters related to or arising in connection with the foregoing. Each Noteholder and beneficial owner of Notes, by its acceptance of a Note or a beneficial interest in a Note, will be deemed to
waive and release any and all claims against the Issuer, the Owner Trustee, the Indenture Trustee, the Calculation Agent, the Paying Agent, the Administrator, the Seller, the Depositor and the Servicer relating to any such determinations. 

(g) None of the Indenture Trustee, the Owner Trustee, the Paying Agent or the Calculation Agent shall be under any obligation (i) to
monitor, determine or verify the unavailability or cessation of SOFR, the Benchmark or Benchmark Replacement or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any event giving rise to the
replacement of the SOFR Rate or a Benchmark Replacement (each of which shall be determined by Administrator), (ii) to select, identify or designate any Benchmark Replacement, or other successor or replacement benchmark index, any Benchmark
Replacement Date, any Benchmark Transition Event, or whether any conditions to the designation of such a rate have been satisfied, (iii) to select, identify or designate any Benchmark Replacement Adjustment, or other modifier to any replacement
or successor index or (iv) to determine whether or what SOFR Conforming Changes, Benchmark Replacement Rate Conforming Changes or other amendments are necessary or advisable, if any, in connection with any of the foregoing. 

(h) None of the Indenture Trustee, the Owner Trustee, the Paying Agent or the Calculation Agent shall be liable for any inability, failure or
delay on its part to perform any of its duties set forth in this Indenture or any other Transaction Document as a result of the unavailability of SOFR Rate or Benchmark and absence of the designation of a Benchmark Replacement Rate, including as a
result of any inability, delay, error or inaccuracy on the part of any other transaction party, including without limitation the Administrator, in providing any direction, instruction, notice or information required or contemplated by the terms of
this Indenture and reasonably required for the performance of such duties. 

  
 21 













 (i) Neither the Indenture Trustee nor the Calculation Agent shall have any liability for any
interest rate published by any publication that is the source for determining the Interest Rates of the Class A-2b Notes, including but not limited to the Reuters Screen (or any successor source), the
FRBNY’s website, the Bloomberg Financial Markets Commodities News or any successor thereto, or for any rates published on any publicly available source or in any of the foregoing cases for any delay, error or inaccuracy in the publication of
any such rates, or for any subsequent correction or adjustment thereto. 
 Section 3.2 Maintenance of Office or Agency. The Note
Registrar shall maintain in Wilmington, Delaware, an office or agency where Notes may be surrendered for registration of transfer or exchange, and where notices and demands to or upon the Note Registrar in respect of the Notes and this Indenture may
be served. The Note Registrar shall give prompt written notice to the Issuer, the Depositor and the Indenture Trustee of the location, and of any change in the location, of any such office or agency. If, at any time, the Issuer and the Note
Registrar shall fail to maintain any such office or agency or shall fail to furnish the Indenture Trustee with the address thereof, such surrenders, notices and demands may be made or served at the Corporate Trust Office, and the Issuer hereby
appoints the Indenture Trustee as its agent to receive all such surrenders, notices and demands. 
 Section 3.3 Money for Payments
To Be Held in Trust. 
 (a) As provided in Section 8.2, all payments of amounts due and payable with respect to the Notes that are
to be made from amounts withdrawn from the applicable Trust Accounts shall be made on behalf of the Issuer by the Indenture Trustee or by another Paying Agent, and no amounts so withdrawn from the applicable Trust Accounts shall be paid over to the
Issuer, except as provided in this Section 3.3. 
 (b) On or before each Distribution Date and Redemption Date, the Issuer shall
deposit or cause to be deposited in the Note Payment Account an aggregate sum sufficient to pay the amounts then becoming due under the Notes, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless the Paying Agent
is the Indenture Trustee) shall promptly notify the Indenture Trustee of its action or failure so to act. 
 (c) The Issuer shall cause each
Paying Agent other than the Indenture Trustee to execute and deliver to the Indenture Trustee an instrument in which such Paying Agent shall agree with the Indenture Trustee (and if the Indenture Trustee acts as Paying Agent, it hereby so agrees),
subject to the provisions of this Section 3.3, that such Paying Agent shall: 
  

	 	(i)	 hold all sums held by it for the payment of amounts due with respect to the Notes in trust for the benefit of
the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided and pay such sums to such Persons as herein provided; 



 

	 	(ii)	 give the Indenture Trustee notice of any default by the Issuer (or any other obligor upon the Notes) of which
it has actual knowledge in the making of any payment required to be made with respect to the Notes; 



  
 22 














	 	(iii)	 at any time during the continuance of any such default, upon the written request of the Indenture Trustee,
forthwith pay to the Indenture Trustee all sums so held in trust by such Paying Agent; 


  

	 	(iv)	 immediately resign as a Paying Agent and forthwith pay to the Indenture Trustee all sums held by it in trust
for payment of the Notes if at any time it ceases to meet the standards required to be met by a Paying Agent at the time of its appointment; and 


  

	 	(v)	 comply with all requirements of the Code and any State or local tax law with respect to the withholding from
any payments made by it on the Notes of any applicable withholding taxes imposed thereon and with respect to any applicable reporting requirements in connection therewith. 



(d) The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, by
Issuer Order direct any Paying Agent to pay to the Indenture Trustee all sums held in trust by such Paying Agent, such sums to be held by the Indenture Trustee upon the same trusts as those upon which such sums were held by such Paying Agent, and
upon such payment by any Paying Agent to the Indenture Trustee, such Paying Agent shall be released from all further liability with respect to such sums. 

(e) Subject to applicable laws with respect to escheat of funds, any money held by the Indenture Trustee or any Paying Agent in trust for the
payment of any amount due with respect to any Note and remaining unclaimed for two (2) years after such amount has become due and payable shall be discharged from such trust and be paid to the Issuer on Issuer Request, and the Holder of such
Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof (but only to the extent of the amounts so paid to the Issuer), and all liability of the Indenture Trustee or such Paying Agent with respect to such
trust money shall thereupon cease; provided, however, that the Indenture Trustee or such Paying Agent, before being required to make any such repayment, shall at the expense and direction of the Issuer cause to be published once, in a
newspaper published in the English language, customarily published on each Business Day and of general circulation in The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less
than thirty (30) days from the date of such publication, any unclaimed balance of such money then remaining shall be repaid to the Issuer. The Indenture Trustee shall also adopt and employ, at the expense and direction of the Issuer, any other
reasonable means of notification of such repayment (including mailing notice of such repayment to Holders whose Notes have been called but have not been surrendered for redemption in whole pursuant to Section 10.1 or whose right to or interest
in monies due and payable but not claimed is determinable from the records of the Indenture Trustee or of any Paying Agent at the last address of record for each such Holder). 

Section 3.4 Existence. The Issuer shall keep in full effect its existence, rights and franchises as a statutory trust under the
laws of the State of Delaware (unless it becomes, or any successor Issuer hereunder is or becomes, organized under the laws of any other State or of the United States, in which case the Issuer shall keep in full effect its existence, rights and
franchises under the laws of such other jurisdiction) and shall obtain and preserve its qualification to do business in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this
Indenture, the Notes, the Collateral and each other instrument or agreement included in the Trust Estate. 

  
 23 













 Section 3.5 Protection of Trust Estate. 

(a) The Issuer shall from time to time authorize, execute and deliver all such supplements and amendments hereto and all such financing
statements, continuation statements, instruments of further assurance and other instruments, and shall take such other action, necessary or advisable to: 
  

	 	(i)	 maintain or preserve the lien and security interest (and the priority thereof) of this Indenture or carry out
more effectively the purposes hereof; 


  

	 	(ii)	 perfect, publish notice of or protect the validity of any Grant made or to be made by this Indenture;



  

	 	(iii)	 enforce any of the Collateral; or 



 

	 	(iv)	 preserve and defend title to the Trust Estate and the rights of the Indenture Trustee and the Noteholders in
the Trust Estate against the claims of all Persons. 


 (b) The Issuer hereby authorizes the Administrator and the
Indenture Trustee to file any financing statement or continuation statement required pursuant to this Section 3.5 and designates the Administrator and the Indenture Trustee as its agent and attorney-in-fact to execute any other instrument required to be executed pursuant to this Section 3.5; it being understood that such authorization shall not be deemed to be an obligation on the part of
the Administrator or the Indenture Trustee to make any such filing. The Issuer further hereby authorizes the Administrator and the Indenture Trustee to file any financing statement and amendments thereto that indicate the Collateral (A) as all
assets of the Issuer, all personal property of the Issuer or words of similar effect, regardless of whether any particular asset included in the Collateral falls within the scope of Article 9 of the Relevant UCC, or (B) as being of an equal or
lesser scope or with greater detail. If the Indenture Trustee prepares or files any such financing statement, continuation statement or amendment thereto, the Indenture Trustee’s responsibility with respect to such financing statement,
continuation statement or amendment shall be subject to the provisions of Sections 6.1 and 6.4 hereof. 
 Section 3.6 Opinions as to
Trust Estate. 
 (a) On the Closing Date, the Issuer shall deliver to the Indenture Trustee an Opinion of Counsel substantially in the
form attached as Exhibit E. 
 (b) On or before March 31 of each year (commencing with the year 2023), the Issuer shall deliver to the
Depositor and the Indenture Trustee an Opinion of Counsel either stating that, in the opinion of such counsel, such action has been taken with respect to the recording, filing, re-recording and refiling of
this Indenture, any indentures supplemental hereto and any other 

  
 24 













 
requisite documents and with respect to the authorization and filing of any financing statements and continuation statements as is necessary to maintain the lien and security interest created by
this Indenture and reciting the details of such action or stating that, in the opinion of such counsel, no such action is necessary to maintain such lien and security interest. Such Opinion of Counsel shall also describe the recording, filing, re-recording and refiling of this Indenture, any indentures supplemental hereto and any other requisite documents and the authorization and filing of any financing statements and continuation statements that shall,
in the opinion of such counsel, be required to maintain the lien and security interest of this Indenture until March 31 in the following year. 

Section 3.7 Performance of Obligations; Servicing of Receivables. 

(a) The Issuer shall not take any action and shall use its best efforts not to permit any action to be taken by others that would release any
Person from any of such Person’s material covenants or obligations under any instrument or agreement included in the Trust Estate or that would result in the amendment, hypothecation, subordination, termination or discharge of, or impair the
validity or effectiveness of, any such instrument or agreement, except as expressly provided in this Indenture and the other Transaction Documents. 

(b) The Issuer may contract with other Persons to assist it in performing its duties under this Indenture, and any performance of such duties
by a Person identified to the Indenture Trustee in an Issuer’s Certificate shall be deemed to be action taken by the Issuer. Initially, the Issuer has contracted with the Servicer and the Administrator to assist the Issuer in performing its
duties under this Indenture. 
 (c) The Issuer shall punctually perform and observe all of its obligations and agreements contained in this
Indenture, the other Transaction Documents and the instruments and agreements included in the Trust Estate, including filing or causing to be filed all financing statements and continuation statements required to be filed under the Relevant UCC by
the terms of this Indenture and the Sale and Servicing Agreement in accordance with and within the time periods provided for herein and therein. 

(d) If the Issuer shall have knowledge of the occurrence of an Event of Servicing Termination, the Issuer shall promptly notify the Depositor,
the Indenture Trustee, the Rating Agencies and the Administrator in writing of such event and shall specify in such notice the action, if any, the Issuer is taking in respect of such default. If an Event of Servicing Termination shall arise from the
failure of the Servicer to perform any of its duties or obligations under the Sale and Servicing Agreement with respect to the Receivables, the Issuer shall take all reasonable steps available to it to remedy such failure. 

(e) As promptly as possible after the giving of notice of termination to the Servicer of the Servicer’s rights and powers pursuant to
Section 8.1 of the Sale and Servicing Agreement, the Issuer may (subject to the rights of the Indenture Trustee to direct such appointment pursuant to Section 8.2 of the Sale and Servicing Agreement) appoint a successor servicer (the
“Successor Servicer”), and such Successor Servicer shall accept its appointment by a written assumption in a form acceptable to the Indenture Trustee. In the event that a Successor Servicer has not been appointed or has not accepted
its appointment at the time when the Servicer 

  
 25 













 
ceases to act as Servicer, the Indenture Trustee, without further action, shall be the successor to the Servicer in all respects in accordance with Section 8.2 of the Sale and Servicing
Agreement. The Indenture Trustee may resign as the Servicer by giving written notice of such resignation to the Issuer and in such event shall be released from such duties and obligations, such release not to be effective until the date a new
servicer enters into a servicing agreement with the Issuer as provided below. Upon delivery of any such notice to the Issuer, the Issuer shall obtain a new servicer as the Successor Servicer under the Sale and Servicing Agreement. Any Successor
Servicer (other than the Indenture Trustee) shall (i) be an established financial institution having a net worth of not less than $50,000,000 and whose regular business includes the servicing of motor vehicle installment sale contracts and
(ii) enter into a servicing agreement with the Issuer having substantially the same provisions as the provisions of the Sale and Servicing Agreement applicable to the Servicer. If, within thirty (30) days after the delivery of the notice
referred to above, the Issuer shall not have obtained such a new servicer, the Indenture Trustee may appoint, or may petition a court of competent jurisdiction to appoint, a Successor Servicer. In connection with any such appointment, the Indenture
Trustee may make such arrangements for the compensation of such successor as it and such successor shall agree, subject to the limitations set forth below and in the Sale and Servicing Agreement, and, in accordance with Section 8.2 of the Sale
and Servicing Agreement, the Issuer shall enter into an agreement with such successor for the servicing of the Receivables (such agreement to be in form and substance satisfactory to the Indenture Trustee). If the Indenture Trustee shall succeed to
the Servicer’s duties as servicer of the Receivables as provided herein, it shall do so in its individual capacity and not in its capacity as Indenture Trustee and, accordingly, the provisions of Article VI shall be inapplicable to the
Indenture Trustee in its duties as the successor to the Servicer and the servicing of the Receivables. In case the Indenture Trustee shall become successor to the Servicer under the Sale and Servicing Agreement, the Indenture Trustee shall be
entitled to appoint as Servicer any one of its Affiliates; provided, however, that the Indenture Trustee, in its capacity as the Servicer, shall be fully liable for the actions and omissions of such Affiliate in such capacity as
Successor Servicer. Notwithstanding any other provisions of this Indenture to the contrary, 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 under the Sale and
Servicing Agreement and the amount necessary to induce any Successor Servicer to act as Successor Servicer under the Sale and Servicing Agreement. 

(f) Upon any termination of the Servicer’s rights and powers pursuant to Section 8.1 of the Sale and Servicing Agreement, the Issuer
shall promptly notify the Depositor, the Indenture Trustee, the Administrator and the Rating Agencies in writing of such termination. Upon any appointment of a Successor Servicer by the Issuer, the Issuer shall promptly notify the Depositor, the
Indenture Trustee, the Administrator and the Rating Agencies in writing of such appointment, specifying in such notice the name and address of such Successor Servicer. 

(g) The Issuer shall not waive timely performance by the Depositor, the Seller or the Servicer of their respective obligations under the
Transaction Documents if such waiver would reasonably be expected to materially adversely affect the interests of the Noteholders. 

  
 26

any lien (including any lien arising in connection with any tax imposed under the Margin Tax), charge, excise, claim, security interest, mortgage or other encumbrance (other than the lien of this Indenture) to be created on or extend to or otherwise
arise upon or burden the Trust Estate or any part thereof or any interest therein or the proceeds thereof (other than tax liens, mechanics’ liens and other liens that arise by operation of law, in each case on any of the Financed Vehicles and
arising solely as a result of an action or omission of the related Obligor) or (C) permit the lien of this Indenture not to constitute a valid and perfected first priority (other than with respect to any such tax, mechanics’ or other lien)
security interest in the Trust Estate; 


  

	 	(v)	 engage in any activities other than financing, acquiring, owning, pledging and managing the Receivables as
contemplated by the Receivables Purchase Agreement, the Trust Agreement, the Sale and Servicing Agreement and this Indenture and activities incidental to such activities; or 



 

	 	(vi)	 incur, assume or guarantee any indebtedness other than the indebtedness evidenced by the Notes or indebtedness
otherwise permitted by the Receivables Purchase Agreement, the Trust Agreement, the Sale and Servicing Agreement or this Indenture.

authorized by each of the Noteholders to make payments to the Indenture Trustee and, in the event that the Indenture Trustee shall consent to the making of payments directly to the Noteholders, to pay to the Indenture Trustee such amounts as shall
be sufficient to cover reasonable compensation to the Indenture Trustee and each predecessor Indenture Trustee, and their respective agents and attorneys, and all other amounts due and owing to the Indenture Trustee pursuant to Section 6.7.



 (e) Nothing herein contained shall be deemed to authorize the Indenture Trustee to authorize or consent to or vote for

Noteholder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar Person. 
 (f) All
rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Indenture Trustee without the possession of any of the Notes or the production thereof in any trial or other Proceedings relative
thereto, and any such action or Proceedings instituted by the Indenture Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of

Section 5.4 Remedies; Priorities. 

(a) If the Notes have been declared immediately due and payable following an Event of Default, the Indenture Trustee may, or at the written
direction of the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class shall, take one or more of the following actions as so directed (subject to Section 5.5): 

 

	 	(i)	 institute Proceedings in its own name and as trustee of an express trust for the collection of all amounts then
payable on the Notes or under this Indenture with respect thereto, whether by declaration or otherwise, enforce any judgment obtained, and collect from the Issuer and any other obligor upon the Notes monies adjudged due; 



 

	 	(ii)	 institute Proceedings from time to time for the complete or partial foreclosure of this Indenture with respect
to the Trust Estate; 


  

	 	(iii)	 exercise any remedies of a secured party under the Relevant UCC and take any other appropriate action to
protect and enforce the rights and remedies of the Indenture Trustee and the Noteholders; and 



  
 38 














	 	(iv)	 sell the Trust Estate or any portion thereof or rights or interest therein at one or more public or private
sales called and conducted in any manner permitted by law; provided, however, that the Indenture Trustee may not sell or otherwise liquidate the Trust Estate at the direction of the Holders following an Event of Default, other than an
Event of Default described in Section 5.1(i) or (ii), unless (A) the Holders of 100% of the Note Balance consent thereto, (B) the proceeds of such sale or liquidation will be sufficient to pay in full the Note Balance and all accrued
but unpaid interest on the Outstanding Notes or (C) the Indenture Trustee determines that the Trust Estate will not continue to provide sufficient funds for the payment of principal of and interest on the Notes as they would have become due if
the Notes had not been declared immediately due and payable, and the Indenture Trustee obtains the consent of the Holders of Notes evidencing not less than 66 2/3% of the Note Balance of the Controlling Class. In determining such sufficiency or
insufficiency with respect to clauses (B) and (C) above, the Indenture Trustee may, but need not, obtain and rely upon an opinion of an Independent investment banking or accounting firm of national reputation as to the feasibility of such
proposed action and as to the sufficiency of the Trust Estate for such purpose. 


 (b) Notwithstanding the provisions of
Section 2.8 or Section 8.2, if the Indenture Trustee collects any money or property pursuant to this Section 5.4 and the Notes have been accelerated, it (or, if the Indenture Trustee is not the Paying Agent, the Paying Agent) shall
pay out such money or property (and other amounts, including all amounts held on deposit in the Reserve Account, except that amounts withdrawn from the Reserve Account will not be distributed to the Certificateholders, used to reimburse Unreimbursed
Servicer Advance, Unrelated Amounts or be paid to CarMax or any of its Affiliates in respect of the Total Servicing Fee owing to the Servicer to the extent that CarMax or any of its affiliates is the Servicer) in the following order of priority:

Section 8.2 of the Sale and Servicing Agreement, any amounts due in connection with indemnification of the Indenture Trustee as Successor Servicer and not paid pursuant to Section 7.2 of the Sale and Servicing Agreement plus any Transition
Costs due in connection with such transfer of servicing and not paid pursuant to Section 8.2(b) of the Sale and Servicing Agreement; (B) to the Indenture Trustee, all amounts due to the Indenture Trustee pursuant to Section 6.7 not

	 	(B)	 to the Holders of each Class of the remaining Class A Notes, pro rata based on the
outstanding principal amount of such Class of Class A Notes as of such Distribution Date, until the principal amount of each such Class of the remaining Class A Notes has been paid in full; 



 

	 	(C)	 to the Class B Noteholders, the Total Note Interest for the Class B Notes; 



 

	 	(D)	 to the Class B Noteholders, until the principal amount of the Class B Notes has been paid in full;



  

	 	(E)	 to the Class C Noteholders, the Total Note Interest for the Class C Notes; 



 

	 	(F)	 to the Class C Noteholders, until the principal amount of the Class C Notes has been paid in full;



  

	 	(G)	 to the Class D Noteholders, the Total Note Interest for the Class D Notes; 



 

	 	(H)	 to the Class D Noteholders, until the principal amount of the Class D Notes has been paid in full;



  

	 	(v)	 fifth, if an Event of Default described in Section 5.1 (iii) or (iv) has occurred, in the following
order of priority: 


  

	 	(A)	 to the Class B Noteholders, the Total Note Interest for the Class B Notes; 



 

	 	(B)	 to the Class C Noteholders, the Total Note Interest for the Class C Notes; 



  
 40

	 	(H)	 to the Class D Noteholders, until the principal amount of the Class D Notes has been paid in full;



  

	 	(vi)	 sixth, if the Indenture Trustee or any other Successor Servicer has become the Servicer pursuant to
Section 8.2 of the Sale and Servicing Agreement, to such Successor Servicer, any Additional Servicing Fee, if any, for the preceding Collection Period and any unpaid Additional Servicing Fees from prior Collection Periods; and



  

	 	(vii)	 seventh, to the Certificateholders, any remaining amounts. 



(c) Prior to an acceleration of the Notes following an Event of Default, if the Indenture Trustee collects any money or property pursuant to
this Article V, such amounts shall be deposited in the Collection Account and distributed in accordance with Section 2.8 and Section 8.2. 

(d) The Indenture Trustee may fix a record date and payment date for any payment to Noteholders pursuant to this Section 5.4. At least
five (5) days before such record date, the Indenture Trustee on behalf of the Issuer shall mail to each Noteholder a notice that states the record date, the payment date and the amount to be paid. 

Section 5.5 Optional Preservation of the Receivables. If the Notes have been declared immediately due and payable following an
Event of Default, and such declaration and its consequences have not been rescinded and annulled, the Indenture Trustee may, but need not, elect to maintain possession of the Trust Estate and apply proceeds as if there had been no declaration of
acceleration; provided, however, that the Available Funds shall be applied in accordance with such declaration of acceleration in the manner specified in Section 5.4(b) as provided in Section 4.6(d) of the Sale and Servicing Agreement. It
is the desire of the parties hereto and the Noteholders that there be at all times sufficient funds for the payment of principal of and interest on the Notes, and the Indenture Trustee shall take such desire into account when determining


  
 41 













 
whether or not to maintain possession of the Trust Estate. In determining whether to maintain possession of the Trust Estate, the Indenture Trustee may, but need not, obtain and rely upon an
opinion of an Independent investment banking or accounting firm of national reputation as to the feasibility of such proposed action and as to the sufficiency of the Trust Estate for such purpose. 

Section 5.6 Limitation of Suits. 

(a) No Holder of any Note shall have any right to institute any Proceeding with respect to this Indenture or for the appointment of a receiver
or trustee, or for any other remedy hereunder, except in accordance with Section 2.4(d) of the Sale and Servicing Agreement, unless: 
  

	 	(i)	 such Holder has previously given written notice to the Indenture Trustee of a continuing Event of Default;



  

	 	(ii)	 the Holders of Notes evidencing not less than 25% of the Note Balance of the Controlling Class have made
written request to the Indenture Trustee to institute such Proceeding in respect of such Event of Default in its own name as Indenture Trustee hereunder; 


  

	 	(iii)	 such Holder or Holders have offered to the Indenture Trustee reasonable indemnity against the costs, expenses
and liabilities to be incurred in complying with such request; 


  

	 	(iv)	 the Indenture Trustee for sixty (60) days after its receipt of such notice, request and offer of indemnity
has failed to institute such Proceedings; and 


  

	 	(v)	 no direction inconsistent with such written request has been given to the Indenture Trustee during such 60-day period by the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class. 



(b) It is understood and intended that no one or more Holders of Notes shall have any right in any manner whatever by virtue of, or by
availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders of Notes or to obtain or to seek to obtain priority or preference over any other Holders of Notes or to enforce any right under this
Indenture, except in the manner herein provided. 
 (c) In the event the Indenture Trustee shall receive conflicting or inconsistent
requests and indemnity from two or more groups of Holders of Notes, each evidencing less than 51% of the Note Balance of the Controlling Class, the Indenture Trustee will take action in accordance with the direction of the greatest amount of Holders
of Notes (measured by principal balance). 
 Section 5.7 Unconditional Rights of Noteholders to Receive Principal and Interest.
Notwithstanding any other provisions of this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest, if any, on such Note on the respective due dates thereof
expressed in such Note or in this Indenture (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such right shall not be impaired without the consent of such Holder. 

  
 42 













 Section 5.8 Restoration of Rights and Remedies. If the Indenture Trustee or any
Noteholder has instituted any Proceeding to enforce any right or remedy under this Indenture and such Proceeding has been discontinued or abandoned for any reason or has been determined adversely to the Indenture Trustee or such Noteholder, then and
in every such case the Issuer, the Indenture Trustee and the Noteholders shall, subject to any determination in such Proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of
the Indenture Trustee and the Noteholders shall continue as though no such Proceeding had been instituted. 
 Section 5.9 Rights and
Remedies Cumulative. No right or remedy herein conferred upon or reserved to the Indenture Trustee or the Noteholders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy. 
 Section 5.10 Delay or Omission Not a Waiver. No delay or
omission of the Indenture Trustee or any Noteholder to exercise any right or remedy accruing upon any Default or Event of Default shall impair any such right or remedy or constitute a waiver of any such Default or Event of Default or any
acquiescence therein. Every right and remedy given by this Article V or by law to the Indenture Trustee or the Noteholders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or the Noteholders, as
the case may be. 
 Section 5.11 Control by Noteholders of the Controlling Class. 

(a) The Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class shall have the right to direct the
time, method and place of conducting any Proceeding for any remedy available to the Indenture Trustee with respect to the Notes or exercising any trust or power conferred on the Indenture Trustee; provided, however, that: 

 

	 	(i)	 such direction shall not be in conflict with any rule of law or with this Indenture or any other Transaction
Document; 


  

	 	(ii)	 subject to the express terms of Section 5.4, any written direction to the Indenture Trustee to sell or
liquidate the Trust Estate shall be by the Holders of Notes evidencing not less than 100% of the Note Balance; 


  

	 	(iii)	 if the conditions set forth in Section 5.5 have been satisfied and the Indenture Trustee elects to retain
the Trust Estate pursuant to such section, then any written direction to the Indenture Trustee by the Holders of Notes evidencing less than 100% of the Note Balance to sell or liquidate the Trust Estate shall be of no force and effect; and




  
 43 














	 	(iv)	 the Indenture Trustee may take any other action deemed proper by the Indenture Trustee that is not inconsistent
with such direction. 


 (b) Notwithstanding the rights of Noteholders set forth in this Section 5.11, subject to
Section 6.1, the Indenture Trustee need not take any action that it reasonably believes might involve it in costs, expenses and liabilities for which it will not be adequately indemnified or might materially adversely affect the rights of any
Noteholders not consenting to such action. 
 Section 5.12 Waiver of Past Defaults. Prior to the declaration of the acceleration
of the maturity of the Notes as provided in Section 5.2, 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 past Default or Event of Default and its
consequences except a Default or Event of Default (i) in the payment of principal of or interest on any of the Notes or (ii) in respect of a covenant or provision hereof that cannot be amended, supplemented or modified without the consent
of all the Noteholders. Upon any such waiver, the Issuer, the Indenture Trustee and the Noteholders shall be restored to their former positions and rights hereunder, respectively, but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereto. Upon any such waiver, such Default or Event of Default shall cease to exist and be deemed to have been cured and not to have occurred, and any Event of Default arising therefrom shall be
deemed to have been cured and not to have occurred, for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto. 

Section 5.13 Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Note by such Holder’s
acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Indenture Trustee for any action taken, suffered
or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorney’s fees,
against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, however, that the provisions of this Section 5.13 shall not apply to (i) any suit
instituted by the Indenture Trustee, (ii) any suit instituted by any Noteholder or group of Noteholders, in each case holding Notes evidencing in the aggregate more than 10% of the Note Balance (or, in the case of any suit which is instituted
by the Controlling Class, more than 10% of the Note Balance of the Controlling Class) or (iii) any suit instituted by any Noteholder for the enforcement of the payment of principal of or interest on any Note on or after the respective due dates
expressed in such Note and in this Indenture (or, in the case of redemption, on or after the Redemption Date). 
 Section 5.14
Waiver of Stay or Extension Laws. The Issuer covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, or plead or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension
law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture, and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 

  
 44 













 Section 5.15 Action on Notes. The Indenture Trustee’s right to seek and
recover judgment on the Notes or under this Indenture shall not be affected by the seeking, obtaining or application of any other relief under or with respect to this Indenture. Neither the lien of this Indenture nor any rights or remedies of the
Indenture Trustee or the Noteholders shall be impaired by the recovery of any judgment by the Indenture Trustee against the Issuer or by the levy of any execution under such judgment upon any portion of the Trust Estate or upon any of the assets of
the Issuer. Any money or property collected by the Indenture Trustee shall be applied in accordance with Section 5.4(b). 

Section 5.16 Performance and Enforcement of Certain Obligations. 

(a) Promptly following a request from the Indenture Trustee to do so, and at the Administrator’s expense (or, if the Indenture Trustee is
then acting as the Administrator, at the expense of CarMax), the Issuer shall take all such lawful action as the Indenture Trustee may request to compel or secure the performance and observance by the Depositor and the Servicer of their respective
obligations to the Issuer under or in connection with the Sale and Servicing Agreement or by the Seller of its obligations under or in connection with the Receivables Purchase Agreement, and to exercise any and all rights, remedies, powers and
privileges lawfully available to the Issuer under or in connection with the Sale and Servicing Agreement to the extent and in the manner directed by the Indenture Trustee, including the transmission of notices of default on the part of the Depositor
or the Servicer thereunder and the institution of legal or administrative actions or proceedings to compel or secure performance by the Depositor and the Servicer of their respective obligations thereunder. 

(b) If an Event of Default shall have occurred and be continuing, the Indenture Trustee may, and at the direction (which direction shall be in
writing or by telephone (confirmed in writing promptly thereafter)) of the Holders of Notes evidencing not less than 66 2/3% of the Note Balance of the Controlling Class shall (subject to Section 6.2(f)), exercise all rights, remedies,
powers, privileges and claims of the Issuer against the Depositor or the Servicer under or in connection with the Sale and Servicing Agreement or against the Seller under or in connection with the Receivables Purchase Agreement, including the right
or power to take any action to compel or secure performance or observance by the Depositor or the Servicer, as the case may be, of its obligations to the Issuer thereunder and to give any consent, request, notice, direction, approval, extension or
waiver under the Sale and Servicing Agreement or the Receivables Purchase Agreement, as the case may be, and any right of the Issuer to take such action shall be suspended. 

(c) Promptly following a request from the Indenture Trustee to do so and at the Administrator’s expense, the Issuer agrees to take all
such lawful action as the Indenture Trustee may request to compel or secure the performance and observance by the Seller of its obligations to the Depositor under or in connection with the Receivables Purchase Agreement in accordance with the terms
thereof, and to exercise any and all rights, remedies, powers and privileges lawfully available to the Issuer under or in connection with the Receivables Purchase Agreement to the extent and in the manner directed by the Indenture Trustee, including
the transmission of notices of default on the part of the Depositor thereunder and the institution of legal or administrative actions or proceedings to compel or secure performance by the Seller of its obligations under the Receivables Purchase
Agreement. 

  
 45 













 (d) If an Event of Default shall have occurred and be continuing, the Indenture Trustee may,
and at the direction (which direction shall be in writing or by telephone (confirmed in writing promptly thereafter)) of the Holders of Notes evidencing not less than 66 2/3% of the Note Balance of the Controlling Class shall (subject to
Section 6.2(f)), exercise all rights, remedies, powers, privileges and claims of the Depositor against the Seller under or in connection with the Receivables Purchase Agreement, including the right or power to take any action to compel or
secure performance or observance by the Seller of its obligations to the Depositor thereunder and to give any consent, request, notice, direction, approval, extension or waiver under the Receivables Purchase Agreement, and any right of the Depositor
to take such action shall be suspended. 
 ARTICLE VI THE INDENTURE TRUSTEE 

Section 6.1 Duties of Indenture Trustee. 

(a) If an Event of Default shall have occurred and be continuing, the Indenture Trustee shall exercise the rights and powers vested in it by
this Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such Person’s own affairs. 

(b) Except during the continuance of an Event of Default: 
  

	 	(i)	 the Indenture Trustee undertakes to perform such duties and only such duties as are specifically set forth in
this Indenture and no implied covenants or obligations shall be read into this Indenture against the Indenture Trustee, and any discretion, permissive right or privilege shall not be deemed to be or otherwise construed as a duty or obligation; and



  

	 	(ii)	 in the absence of bad faith on its part, the Indenture Trustee may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Indenture Trustee and, if required by the terms of this Indenture, conforming to the requirements of this Indenture; provided,
however, that the Indenture Trustee shall examine the certificates and opinions to determine whether or not they conform on their face to the requirements of this Indenture. 



(c) The Indenture Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful
misconduct, except that: 
  

	 	(i)	 this paragraph does not limit the effect of paragraph (b) of this Section 6.1; 



 

	 	(ii)	 the Indenture Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer
unless it is proved that the Indenture Trustee was negligent in ascertaining the pertinent facts; 



  
 46 














	 	(iii)	 the Indenture Trustee shall not be liable with respect to any action it takes or omits to take in good faith in
accordance with a direction received by it pursuant to Section 5.11; and 


  

	 	(iv)	 the Indenture Trustee shall not be liable for special, punitive, consequential, or indirect damages (including,
among other things, lost profits). 


 (d) The Indenture Trustee shall not be liable for interest on any money received by
it except as the Indenture Trustee may agree in writing with the Issuer. 
 (e) Money held in trust by the Indenture Trustee need not be
segregated from other funds except to the extent required by law or the terms of this Indenture or the Sale and Servicing Agreement. 
 (f)
No provision of this Indenture shall require the Indenture Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers hereunder
if the Indenture Trustee shall have reasonable grounds to believe that repayment of such funds or indemnity satisfactory to it against such risk or liability is not assured or provided to it. 

(g) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Indenture Trustee
shall be subject to the provisions of this Section 6.1 and the TIA. 
 (h) The Indenture Trustee shall not be charged with knowledge of
any Event of Default, breach of a representation or warranty of any other party to the Transaction Documents or of any other event unless either (i) a Responsible Officer shall have actual knowledge of such Event of Default, breach of a
representation or warranty or other event or (ii) written notice of such Event of Default, breach of a representation or warranty or other event shall have been given to a Responsible Officer of the Indenture Trustee in accordance with the
provisions of this Indenture; provided, however, that for the avoidance of doubt, the Indenture Trustee shall not be deemed to have knowledge of a breach of representation or warranty solely as a result of the receipt and possession by the Indenture
Trustee of the Review Report (as defined in the Asset Representations Review Agreement). Except as expressly provided in this Indenture, the Indenture Trustee shall have no duty to take any action to determine whether any Event of Default or other
event has occurred. 
 (i) The Indenture Trustee shall be required to carry out its duties as specified in Sections 4.1, 4.7, 4.9, 7.4(c),
8.1, 8.2, 8.3(a), 8.4, 10.12 and 10.14 of the Sale and Servicing Agreement. In furtherance of the foregoing, Sections 4.1, 4.7, 4.9, 7.4(c), 8.1, 8.2, 8.3(a), 8.4, 10.12 and 10.14 of the Sale and Servicing Agreement are hereby incorporated by
reference into this Indenture to the extent that they refer to obligations of the Indenture Trustee. 
 (j) Subject to Sections 6.1(a) and
(c), in no event shall the Indenture Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without
limitation, strikes, work stoppages, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities; it being understood that the Indenture Trustee shall
use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

  
 47 













 (k) The Indenture Trustee shall have the right to decline to follow any investor direction
if the Indenture Trustee determines that the action or proceeding as directed may not lawfully be taken or conflicts with this Indenture or other Transaction Document or if the Indenture Trustee in good faith determines that the action or proceeding
so directed would involve it in personal liability or be unjustly prejudicial to the non-directing holders. 

(l) The Indenture Trustee shall not have any obligation to investigate any matter or to exercise any powers vested by the Indenture Trustee
unless requested by 25% or more of the Holders, and such Holders have assured to the Indenture Trustee indemnity satisfactory to it. 

Section 6.2 Rights of Indenture Trustee. 

(a) The Indenture Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the
proper Person. 
 (b) Before the Indenture Trustee acts or refrains from acting, it may request and shall be entitled to receive an
Issuer’s Certificate or an Opinion of Counsel. The Indenture Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on an Issuer’s Certificate or Opinion of Counsel. 

(c) The Indenture Trustee in any of its capacities may execute any of the trusts or powers hereunder or perform any duties hereunder either
directly or by or through agents or attorneys or a custodian or nominee, and the Indenture Trustee shall not be responsible for any misconduct or negligence on the part of, or for the supervision of, any such agent, attorney, custodian or nominee
appointed with due care by it hereunder. 
 (d) The Indenture Trustee shall not be liable for any action it takes or omits to take in good
faith which it believes to be authorized or within its rights or powers; provided, however, that such action or omission by the Indenture Trustee does not constitute willful misconduct, negligence or bad faith. 

(e) The Indenture Trustee may consult with counsel, and the advice or opinion of counsel with respect to legal matters relating to this
Indenture and the Notes shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel. 

(f) The Indenture Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request
or direction of the Noteholders pursuant to this Indenture, unless such Noteholders shall have offered to the Indenture Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction.

 (g) The Indenture Trustee shall not be bound to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Indenture Trustee, in its discretion, may make such further
inquiry or investigation into such facts or matters as it may see fit, and, if the Indenture Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer,
personally or by agent or attorney. In no event shall the Indenture Trustee have any responsibility to monitor CarMax’s compliance with or be charged with knowledge of the risk retention rules of 17 CFR Part 246, nor shall it be liable to any
investor, Holder, or any party whatsoever for violation of such rules or requirements or such similar provisions now or hereafter in effect. 

(h) Any permissive right or privilege of the Indenture Trustee hereunder shall not be deemed to be or otherwise construed as a duty or
obligation. 
 (i) The Indenture Trustee shall not be liable for the failure to perform its duties hereunder if such failure is a direct or
proximate result of another party failing to perform its duties. 
 Section 6.3 Individual Rights of Indenture Trustee. The
Indenture Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Indenture Trustee. Any Paying Agent,
Calculation Agent, Note Registrar, co-registrar or co-paying agent hereunder may do the same with like rights. 

Section 6.4 Indenture Trustee’s Disclaimer. The Indenture Trustee (i) shall not be responsible for, and
makes no representation as to, the validity or adequacy of this Indenture or the Notes, (ii) shall not be accountable for the Issuer’s use of the proceeds from the Notes or responsible for any statement of the Issuer in this Indenture or
in any document issued in connection with the sale of the Notes or in the Notes other than the Indenture Trustee’s certificate of authentication and (iii) shall not be responsible for the acts or omissions of any other party, including the
Servicer, Seller and Depositor, and may assume each other party’s performance of its obligations under the Trust Agreement, the Receivables Purchase Agreement and the Sale and Servicing Agreement absent written notice or actual knowledge of a
Responsible Officer to the contrary. 
 Section 6.5 Notice of Defaults. If an Event of Default occurs and is continuing and if
it is known to a Responsible Officer of the Indenture Trustee, the Indenture Trustee shall mail to each Noteholder and the Administrator notice of such Event of Default within ninety (90) days after it occurs. Except in the case of an Event of
Default described in Section 5.1(a)(i) or (ii) (including payments pursuant to the mandatory redemption provisions of such Note), the Indenture Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good
faith determines that withholding the notice is in the interests of Noteholders. 
 Section 6.6 Reports by Indenture Trustee to
Holders. The Indenture Trustee shall make available, within a reasonable period of time after the end of each calendar year, to each Person who at any time during such calendar year was a Noteholder, such information furnished to the Indenture
Trustee as may be required to enable such Person to prepare its federal and State income tax returns. 

  
 49 













 Section 6.7 Compensation and Indemnity. 

(a) The Administrator, on behalf of the Issuer, shall pay to the Indenture Trustee from time to time reasonable compensation for its services.
The Indenture Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Administrator, on behalf of the Issuer, shall reimburse the Indenture Trustee for all expenses, advances and
disbursements reasonably incurred or made by it, including costs of collection, in addition to the compensation for its services; provided, however, that the Administrator need not reimburse the Indenture Trustee for any expense incurred through the
Indenture Trustee’s willful misconduct, negligence, or bad faith. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Indenture Trustee’s agents, counsel, accountants and experts. The
Administrator, on behalf of the Issuer, shall indemnify the Indenture Trustee for, and hold it and its officers, directors, employees, representatives and agents, harmless against, any and all loss, liability, cost or expense (including reasonable
attorneys’ fees and expenses and court costs, and any loss or expense incurred in connection with a successful defense, in whole or in part, of any claim that the Indenture Trustee breached its standard of care) incurred by it in connection
with the administration of this trust and the performance of its duties hereunder, including those incurred in connection with any action, claim or suit brought to enforce the Indenture Trustee’s right to indemnification; provided, however,
that the Administrator need not indemnify the Indenture Trustee for, or hold it harmless against, any such loss, liability, cost or expense incurred through the Indenture Trustee’s willful misconduct, negligence, or bad faith. The Indenture
Trustee shall notify the Issuer and the Administrator promptly of any claim for which it may seek indemnity. Any failure by the Indenture Trustee to so notify the Issuer and the Administrator shall not, however, relieve the Administrator of its
obligations hereunder. The Administrator, on behalf of the Issuer, shall defend any such claim. The Indenture Trustee may have separate counsel in connection with the defense of any such claim, and the Administrator, on behalf of the Issuer, shall
pay the fees and expenses of such counsel. If the Indenture Trustee is then acting as Administrator, all payment obligations to the Indenture Trustee pursuant to this Section 6.7 shall be paid by CarMax. 

(b) The payment obligations to the Indenture Trustee pursuant to this Section 6.7 shall survive the resignation or removal of the
Indenture Trustee and the discharge of this Indenture. 
 (c) When the Indenture Trustee incurs fees or expenses after the occurrence of a
Default specified in Section 5.1(a)(v) or Section 5.1(a)(vi) with respect to the Issuer, such fees and expenses are intended to constitute expenses of administration under Title 11 of the United States Code or any other applicable federal
or State bankruptcy, insolvency or similar law. 
 Section 6.8 Replacement of Indenture Trustee. 

(a) No resignation or removal of the Indenture Trustee, and no appointment of a successor Indenture Trustee, shall become effective until the
acceptance of appointment by the successor Indenture Trustee pursuant to this Section 6.8. The Indenture Trustee may resign at any time by providing the Issuer, the Administrator, the Depositor and the Noteholders with at least 60 days’
advance written notice. The Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class may remove the Indenture Trustee without cause by notifying the Indenture Trustee (with a copy to the Issuer, the
Administrator, the Depositor and the Rating Agencies) of such removal and, following such removal, may appoint a successor Indenture Trustee. The Issuer shall remove the Indenture Trustee if: 

 

	 	(i)	 the Indenture Trustee fails to comply with Section 6.11; 



  
 50 














	 	(ii)	 the Indenture Trustee is adjudged to be bankrupt or insolvent; 



 

	 	(iii)	 a receiver or other public officer takes charge of the Indenture Trustee or its property; or



  

	 	(iv)	 the Indenture Trustee otherwise becomes incapable of acting. 



(b) If the Indenture Trustee resigns or is removed or if a vacancy exists in the office of Indenture Trustee for any reason (the Indenture
Trustee in such event being referred to herein as the retiring Indenture Trustee), the Administrator shall promptly appoint a successor Indenture Trustee. 

(c) Any successor Indenture Trustee shall deliver a written acceptance of its appointment to the retiring Indenture Trustee, the Issuer, the
Administrator and the Depositor. Upon delivery of such written acceptance, the resignation or removal of the retiring Indenture Trustee shall become effective and the successor Indenture Trustee shall have all the rights, powers and duties of the
Indenture Trustee under this Indenture. The successor Indenture Trustee shall mail a notice of its succession to the Noteholders. The retiring Indenture Trustee shall promptly transfer all property held by it as Indenture Trustee to the successor
Indenture Trustee. 
 (d) If a successor Indenture Trustee does not take office within sixty (60) days after the retiring Indenture
Trustee resigns or is removed, the retiring Indenture Trustee, the Issuer or the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class may petition any court of competent jurisdiction for the appointment of
a successor Indenture Trustee. If the Indenture Trustee fails to comply with Section 6.11, any Noteholder may petition any court of competent jurisdiction for the removal of the Indenture Trustee and the appointment of a successor Indenture
Trustee. 
 (e) Notwithstanding the replacement of the Indenture Trustee pursuant to this Section 6.8, the Administrator’s
obligations under Section 6.7 shall continue for the benefit of the retiring Indenture Trustee. 
 Section 6.9 Successor
Indenture Trustee by Merger. 
 (a) If the Indenture Trustee consolidates with, merges or converts into, or transfers all or
substantially all its corporate trust business or assets to another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Indenture Trustee;
provided, however, that such corporation or banking association must be otherwise qualified and eligible under Section 6.11. The Indenture Trustee shall provide the Rating Agencies, the Administrator and the Depositor with prior
written notice of any such transaction. 

  
 51 













 (b) If at the time such successor or successors by consolidation, merger or conversion to
the Indenture Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have been authenticated but not delivered, any such successor to the Indenture Trustee may adopt the certificate of authentication of any predecessor
trustee and deliver such Notes so authenticated, and in case at that time any of the Notes shall not have been authenticated, any such successor to the Indenture Trustee may authenticate such Notes either in the name of any predecessor trustee or in
the name of the successor to the Indenture Trustee. In all such cases such certificates shall have the full force which the Notes or this Indenture provide that the certificate of the Indenture Trustee shall have. 

Section 6.10 Appointment of Co-Indenture Trustee or Separate Indenture Trustee. 

(a) Notwithstanding any other provisions of this Indenture, at any time, for the purpose of meeting any legal requirement of any jurisdiction
in which any part of the Trust Estate may at the time be located, the Indenture Trustee shall have the power and may execute and deliver an instrument to appoint one or more Persons to act as a co-trustee or co-trustees, jointly with the Indenture Trustee, or separate trustee or separate trustees, of all or any part of the Trust Estate, and to vest in such Person or Persons, in such capacity and for the benefit of the
Noteholders, such title to the Trust Estate, or any part hereof, and, subject to the other provisions of this Section 6.10, such powers, duties, obligations, rights and trusts as the Indenture Trustee may consider necessary or desirable. No co-trustee or separate trustee under this Indenture shall be required to meet the terms of eligibility as a successor trustee under Section 6.11 and no notice of the appointment of any co-trustee or separate trustee shall be required under Section 6.8. 
 (b) Each separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions: 
  

	 	(i)	 all rights, powers, duties and obligations conferred or imposed upon the Indenture Trustee shall be conferred
or imposed upon and exercised or performed by the Indenture Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or
co-trustee shall not be authorized to act separately without the Indenture Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to
be performed the Indenture Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust Estate or any portion thereof in any such
jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Indenture Trustee; 



 

	 	(ii)	 no trustee under this Indenture shall be personally liable by reason of any act or omission of any other
trustee under this Indenture; and 


  

	 	(iii)	 the Indenture Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee. 



  
 52 













 (c) Any notice, request or other writing given to the Indenture Trustee shall be deemed to
have been given to each of the then separate trustees and co-trustees as effectively as if given to each of them. Every instrument appointing any separate trustee or
co-trustee shall refer to this Indenture and the conditions of this Article VI. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall
be vested with the estates or property specified in its instrument of appointment, either jointly with the Indenture Trustee or separately, as may be provided therein, subject to all the provisions of this Indenture, specifically including every
provision of this Indenture relating to the conduct of, affecting the liability of, or affording protection to, the Indenture Trustee. Each such instrument shall be filed with the Indenture Trustee. 

(d) Any separate trustee or co-trustee may at any time constitute the Indenture Trustee its agent or attorney-in-fact with full power and authority, to the extent permitted by law, to do any lawful act under or in respect of this Indenture on its behalf and in its name. If
any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Indenture
Trustee, to the extent permitted by law, without the appointment of a new or successor trustee. 
 Section 6.11 Eligibility;
Disqualification. 
 (a) The Indenture Trustee shall at all times satisfy the requirements of TIA Section 310(a). The Indenture

Indenture Trustee shall comply with TIA Section 310(b). 
 (b) The Indenture Trustee shall comply with TIA Section 310(b),

securities of the Issuer are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. 
 (c) In
the case of the appointment pursuant to this Section 6.11 of a successor Indenture Trustee with respect to any Class of Notes, the Issuer, the retiring Indenture Trustee and the successor Indenture Trustee with respect to such
Class of Notes shall execute and deliver an indenture supplemental hereto wherein each successor Indenture Trustee shall accept such appointment and which (i) shall contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, the successor Indenture Trustee all the rights, powers, trusts and duties of the retiring Indenture Trustee with respect to the Notes of the Class to which the appointment of such successor Indenture Trustee relates,
(ii) if the retiring Indenture Trustee is not retiring with respect to all Classes of Notes, shall contain such provisions as shall be deemed necessary or desirable to confirm that all rights, powers, trusts and duties of the retiring Indenture
Trustee with respect to the Notes of each Class as to which the retiring Indenture Trustee is not retiring shall continue to be vested in the Indenture Trustee and (iii) shall add to or change any of the provisions of this Indenture as
shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Indenture Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Indenture Trustees co-trustees of the same trust and that each such Indenture Trustee shall be a trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Indenture
Trustee; and upon the removal of the retiring Indenture Trustee shall become effective to the extent provided herein. 

  
 53 













 Section 6.12 Preferential Collection of Claims Against Issuer. The Indenture

Section 6.13 Communications Regarding Demands to Purchase Receivables. The Indenture Trustee agrees to cooperate in good faith
with any reasonable request by the Depositor for information which is required in order to enable the Depositor to comply with the provisions of Items 1104(e) and 1121(c) of Regulation AB and Rule 15Ga-1 under
the Exchange Act as it relates to the Indenture Trustee or to the Indenture Trustee’s obligations under this Indenture. The Indenture Trustee shall provide the Depositor with notification, as soon as practicable and in any event within five
(5) Business Days, of (i) all demands communicated to the Indenture Trustee for the repurchase or replacement of any Receivable and (ii) all requests by Verified Note Owners to communicate with other Noteholders regarding the exercise

(if the Notes are represented by Book-Entry Notes) may communicate with the Indenture Trustee and give notices and make requests and demands and give directions to the Indenture Trustee through the procedures of the Clearing Agency and by notice to
the Indenture Trustee. In the event that a Verified Note Owner 

  
 55 













 
communicates with the Indenture Trustee, the Indenture Trustee shall provide a copy of the supporting evidence provided to the Indenture Trustee to the Issuer. The Indenture Trustee will not be
required to take action in response to requests, demands or directions of a Noteholder or a Verified Note Owner, other than requests, demands or directions relating to obligations of the Indenture Trustee in connection with an Asset Representations
Review Notice explicitly set forth in Section 7.6, unless the Noteholder or Verified Note Owner has offered reasonable security or indemnity reasonably satisfactory to the Indenture Trustee to protect it against the fees and expenses that it
may incur in complying with the request, demand or direction. 
 (b) Communications between Noteholders. A Noteholder (if the Notes
are represented by Definitive Notes) or a Note Owner (if the Notes are represented by Book-Entry Notes) that seeks to communicate with other Noteholders or Note Owners, as applicable, about a possible exercise of rights under this Indenture or the
other Transaction Documents may send a request to the Servicer, on behalf of the Issuer, at CMX_Corp_Fin_Dept@carmax.com to include information regarding the communication in a Form 10-D to be filed by the

and (iii) in the case of a Note Owner, evidence of and a certification from that Person that it is a Verified Note Owner. A Noteholder or Verified Note Owner, as applicable, that delivers a request under this Section 7.5(b) will be deemed
to have certified to the Issuer and the Servicer that its request to communicate with other Noteholders or Note Owners, as applicable, relates solely to a possible exercise of rights under this Indenture or the other Transaction Documents, and will
not be used for other purposes. The Issuer will promptly deliver any such request to the Servicer. On receipt of such a request, the Servicer will include in the Form 10-D filed by the Issuer with the
Commission for the Collection Period in which the request was received (A) a statement that the Servicer has received a request from a Noteholder or Note Owner, as applicable, that is interested in communicating with other Noteholders or Note
Owners, as applicable, about a possible exercise of rights under this Indenture or the other Transaction Documents, (B) the name of the requesting Noteholder or Note Owner, (C) the date the request was received and (D) a description
of the method by which the other Noteholders or Note Owners, as applicable, may contact the requesting Noteholder or Note Owner. Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a
Note, covenants and agrees that such requesting Noteholder or Note Owner will pay any costs associated with communicating with other Noteholders or Note Owners, and none of the Seller, the Servicer, the Depositor, the Issuer, the Administrator, the
Indenture Trustee or the Owner Trustee will be responsible for such costs. 
 Section 7.6 Asset Representations Review. 

(a) If a Delinquency Trigger Event occurs, a Noteholder (if the Notes are represented by Definitive Notes) or a Verified Note Owner (if the
Notes are represented by Book-Entry Notes) may make a demand on the Indenture Trustee to cause a vote of the Noteholders or Note Owners, as applicable, about whether to direct the Asset Representations Reviewer to conduct an Asset Representations
Review. If Noteholders and Note Owners of 5% or more of the aggregate principal amount of all Notes Outstanding demand a vote within 90 days of the filing of the Form 10-D indicating that the Delinquency
Trigger Event has occurred, the Indenture Trustee will promptly request a vote of the Noteholders and Note Owners as described in Section 7.6(b) below; provided, that for the purpose of determining the holders of the Notes Outstanding,
any Notes held by CarMax or any of its Affiliates shall not be included in such calculation. 

  
 56 













 (b) Upon the direction of the requisite Noteholders or Note Owners set forth in
Section 7.6(a), the Indenture Trustee shall conduct a vote of all Noteholders, and shall cause the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.) to conduct a vote of all Note Owners. The Indenture Trustee
shall provide to the Servicer the voting instructions and procedures applicable to the Noteholders and Note Owners to be included in the Form 10-D filed by the Issuer with the Commission. Each Noteholder or
Note Owner that elects to vote shall vote whether or not the Asset Representations Reviewer should be directed to conduct an Asset Representations Review. Noteholders or Note Owners shall be permitted to vote for 150 days after the filing of the
Form 10-D indicating that the Delinquency Trigger Event has occurred. 
 (c) In the event that a
Verified Note Owner exercises its right to vote such Note Owner’s beneficial interest, the Indenture Trustee shall provide a copy of the supporting evidence provided to the Indenture Trustee to the Issuer. 

(d) If (i) a majority of the Noteholders and Note Owners voting pursuant to Section 7.6(b) vote to cause the Asset Representations
Reviewer to conduct an Asset Representations Review and (ii) the holders of 5% or more of the aggregate principal amount of Outstanding Notes cast a vote, the Indenture Trustee shall provide a notice to the Issuer (the “Asset
Representations Review Notice”), which shall promptly provide such Asset Representations Review Notice to the Seller, the Depositor and the Servicer. 

(e) The Indenture Trustee shall cooperate with the Asset Representations Reviewer in the event an Asset Representations Review is commenced
pursuant to Section 7.6(d) and shall provide the Asset Representations Reviewer with any documents or other information in its possession reasonably requested by the Asset Representations Reviewer in connection with the Asset Representations
Review.

Sale and Servicing Agreement. The Indenture Trustee shall apply all such money received by it as provided in this Indenture and the Sale and Servicing Agreement. Except as otherwise expressly provided in this Indenture, if any default occurs in the
making of any payment or performance under any agreement or instrument that is part of the Trust Estate, the Indenture Trustee may take such action as may be appropriate to enforce such payment or performance, including the institution and

Trustee shall apply or cause to be applied the amount on deposit in the Note Payment Account on such Distribution Date in accordance with Section 2.8(a) or (d), as applicable. 

Section 8.3 General Provisions Regarding Accounts. 

(a) So long as no Default or Event of Default shall have occurred and be continuing, all or a portion of the funds in the Trust Accounts shall
be invested by the Indenture Trustee at the written direction of the Servicer in Permitted Investments as provided in Sections 4.1 and 4.7 of the Sale and Servicing Agreement; provided, that, funds on deposit in the Reserve Account shall be
invested in Permitted Investments meeting the requirements of 17 CFR Part 246.4(b)(2), as determined by the Servicer. All income or other gain (net of losses and investment expenses) from investments of monies deposited in the Trust Accounts shall
be withdrawn by the Indenture Trustee from such accounts and distributed (but only under the circumstances set forth in the Sale and Servicing Agreement) as provided in Sections 4.1 and 4.7 of the Sale and Servicing Agreement; provided, that
amounts released from the Reserve Account shall meet the requirements of 17 CFR Part 246.4(b)(3)(i), as determined by the Servicer. The Servicer shall not direct the Indenture Trustee to make any investment of any funds or to sell any investment
held in any of the Trust Accounts unless the security interest granted and perfected in such account will continue to be perfected in such investment or the proceeds of such sale, in either case without any further action by any Person, and, in
connection with any direction to the Indenture Trustee to make any such investment or sale, if requested by the Indenture Trustee, the Issuer shall deliver to the Indenture Trustee an Opinion of Counsel, acceptable to the Indenture Trustee, to such
effect.

liable by reason of any insufficiency in any of the Trust Accounts resulting from any loss on any Permitted Investment included therein, except for losses attributable to the Indenture Trustee’s failure to make payments on such Permitted
Investments issued by the Indenture Trustee, in its commercial capacity as principal obligor and not as trustee, in accordance with their terms. 

(c) If (i) the Servicer shall have failed to give written investment directions for any funds on deposit in the Trust Accounts to the

reinvest funds in the Trust Accounts in one or more Permitted Investments in accordance with the standing instructions most recently given by the Servicer; provided, however, that if no standing instructions shall have been given to the Indenture
Trustee, the funds shall remain uninvested.

thereto any funds then on deposit in the Trust Accounts; provided, that, any amounts on deposit in the Reserve Account shall be distributable only to the Depositor following the final distribution to the Certificateholders. The Indenture

contemplated by Section 8.4(b), as a condition to such action, an Opinion of Counsel, addressed to the Indenture Trustee, stating the legal effect of any such action, outlining the steps required to complete such action, and concluding that all
conditions precedent to the taking of such action have been complied with and such action will not materially and adversely impair the security for the Notes or the rights of the Noteholders in contravention of the provisions of this Indenture;
provided, however, that such Opinion of Counsel shall not be required to express an opinion as to the fair value of the Trust Estate. Counsel rendering any such opinion may rely, without independent investigation, on the accuracy and validity of any
certificate or other instrument delivered to the Indenture Trustee in connection with any such action.

particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. Promptly after the execution by the Issuer and the Indenture Trustee of any supplemental indenture pursuant to this
Section 9.2, the Indenture Trustee shall mail to the Holders of the Notes to which such amendment or supplemental indenture relates a notice setting forth in general terms the substance of such supplemental indenture. Any failure of the
Indenture Trustee to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture. 

Section 9.3 Execution of Supplemental Indentures. In executing, or permitting the additional trusts created by, any supplemental
indenture permitted by this Article IX or the modification thereby of the trusts created by this Indenture, the Indenture Trustee shall be entitled to receive and, subject to Section 6.1 and Section 6.2, shall be fully protected in relying
upon an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or 

  
 62 













 
permitted by this Indenture and that all conditions precedent in this Indenture to the execution and delivery of such supplemental indenture have been satisfied. The Indenture Trustee may, but
shall not be obligated to, enter into any such supplemental indenture that affects the Indenture Trustee’s own rights, duties, liabilities or immunities under this Indenture or otherwise. Notwithstanding anything in this Indenture to the
contrary, no supplemental indenture shall be effective without the prior written consent of the Owner Trustee or the Asset Representations Reviewer, respectively, if the supplemental indenture would adversely modify the amount or timing of
distributions to be made to the Owner Trustee or the Asset Representations Reviewer, as applicable, under this Indenture. 

Section 9.4 Effect of Supplemental Indenture. Upon the execution of any supplemental indenture pursuant to the provisions hereof,

supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

Section 9.5 Conformity with Trust Indenture Act. Every amendment of this Indenture and every supplemental indenture executed
pursuant to this Article IX shall conform to the requirements of the Trust Indenture Act as then in effect so long as this Indenture shall then be qualified under the Trust Indenture Act. 

Section 9.6 Reference in Notes to Supplemental Indentures. Any Notes authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article IX may, and if required by the Indenture Trustee shall, bear a notation in form approved by the Indenture Trustee as to any matter provided for in such supplemental indenture. If the Issuer or the
Indenture Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Indenture Trustee and the Issuer, to any such supplemental indenture may be prepared and executed by the Issuer and authenticated and delivered by the
Indenture Trustee in exchange for Outstanding Notes.

to the fair value (within ninety (90) days of such release) of the property or securities proposed to be released and stating that in the opinion of such person the proposed release will not impair the security under this Indenture in

and to the extent permitted or required by the Transaction Documents and (ii) make cash payments out of the Trust Accounts as and to the extent permitted or required by the Transaction Documents. 

Section 11.2 Form of Documents Delivered to Indenture Trustee. 

(a) In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary
that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more
other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. 

  
 66 













 (b) Any certificate or opinion of an Authorized Officer of the Issuer may be based, insofar
as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the
matters upon which such officer’s certificate or opinion is based are erroneous. Any such certificate of an Authorized Officer or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, one or more officers of the Depositor, the Seller, the Servicer, the Administrator or the Issuer, stating that the information with respect to such factual matters is in the possession of the Depositor, the Seller, the Servicer,

in connection with any application or certificate or report to the Indenture Trustee, it is provided that the Issuer shall deliver any document as a condition of the granting of such application, or as evidence of the Issuer’s compliance with
any term hereof, it is intended that the truth and accuracy, at the time of the granting of such application or at the effective date of such certificate or report (as the case may be), of the facts and opinions stated in such document shall in such
case be conditions precedent to the right of the Issuer to have such application granted or to the sufficiency of such certificate or report. The foregoing shall not, however, be construed to affect the Indenture Trustee’s right to rely upon
the truth and accuracy of any statement or opinion contained in any such document as provided in Article VI. 
 Section 11.3 Acts of
Noteholders. 
 (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by the Noteholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by the Noteholders in person or by agents duly appointed in writing, and except as herein otherwise expressly
provided such action shall become effective when such instrument or instruments are delivered to the Indenture Trustee and, where it is hereby expressly required, to the Issuer. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the “Act” of the Noteholders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for
any purpose of this Indenture and (subject to Section 6.1) conclusive in favor of the Indenture Trustee and the Issuer, if made in the manner provided in this Section 11.3.

action is made upon such Note.

made, given, furnished or filed in writing to or with the Indenture Trustee at its Corporate Trust Office; 


  

	 	(ii)	 the Issuer by the Indenture Trustee or by any Noteholder, shall be sufficient for every purpose hereunder if in

by the Issuer or the Administrator; 


  

	 	(iii)	 the Depositor by the Indenture Trustee, the Servicer or any Noteholder, it shall be sufficient for every
purpose hereunder if in writing and sent by first-class mail, postage prepaid, or overnight courier to the Depositor addressed to CarMax Auto Funding LLC at 12800 Tuckahoe Creek Parkway, Suite 400, Richmond, Virginia 23238, Attention: Treasurer; or



  

	 	(iv)	 the Administrator by the Indenture Trustee, the Issuer, the Servicer, the Depositor or any Noteholder, shall be
sufficient for every purpose hereunder if in writing and sent by first-class mail, postage prepaid, or overnight courier to the Administrator addressed to CarMax Business Services, LLC at 12800 Tuckahoe Creek Parkway, Richmond, Virginia 23238,

 (b) Notices required to be given to the Rating Agencies by the Issuer, the Indenture
Trustee or the Owner Trustee shall be in writing, personally delivered, telecopied or mailed by certified mail, return receipt requested, to the Administrator and the Issuer shall cause the Administrator to promptly provide such notices (i) in
the case of Fitch Ratings, Inc., at the following address: 33 Whitehall Street, New York, New York, 10004, Attention: Auto Asset 

  
 68 













 
Backed Securities Group, and via email to surveillance-abs-auto@fitchratings.com and (ii) in the case of
S&P Global Ratings, at the following address: S&P Global Ratings, 55 Water Street, New York, New York 10041, Attention: Asset Backed Surveillance Department, and via email to servicer_reports@spglobal.com. The Issuer shall promptly transmit
any notice received by it from the Noteholders to the Indenture Trustee. The Indenture Trustee shall likewise promptly transmit any notice received by it from the Noteholders or Note Owners to the Issuer and, if such notice is a Repurchase Request,
to the Depositor. 
 Section 11.5 Notices to Noteholders; Waiver. 

(a) Where this Indenture provides for notice to Noteholders of any event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class, postage prepaid to each Noteholder affected by such event, at its address as it appears on the Note Register, not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice. In any case where notice to Noteholders is given by mail, neither the failure to mail such notice nor any defect in any notice so mailed to any particular Noteholder shall affect the sufficiency of such
notice with respect to other Noteholders, and any notice that is mailed in the manner herein provided shall conclusively be presumed to have been duly given. 

(b) Where this Indenture provides for notice in any manner, such notice may be waived in writing by any Person entitled to receive such
notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Noteholders shall be filed with the Indenture Trustee, but such filing shall not be a condition precedent to the validity of any
action taken in reliance upon such a waiver. 
 (c) If, by reason of the suspension of regular mail service as a result of a strike, work
stoppage or similar activity, it shall be impractical to mail notice of any event to Noteholders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to
the Indenture Trustee shall be deemed to be a sufficient giving of such notice. 
 (d) Where this Indenture provides for notice to the
Rating Agencies, failure to give such notice shall not affect any other rights or obligations created hereunder, and shall not under any circumstance constitute a Default or Event of Default. 

(e) If the Indenture Trustee receives a Repurchase Request and the Depositor or CarMax does not repurchase the Receivables related to such
Repurchase Request within one hundred eighty (180) days of the receipt of such Repurchase Request, the Indenture Trustee, at the direction of the Administrator pursuant to Section 2(b)(viii) of the Administration Agreement, shall deliver a
Repurchase Response Notice to the related Noteholder or Note Owner. 
 Section 11.6 Alternate Payment and Notice Provisions.
Notwithstanding any other provisions of this Indenture or any of the Notes to the contrary, the Issuer may enter into any agreement with any Holder of a Note providing for a method of payment, or notice by the Indenture Trustee or any Paying Agent
to such Holder, that is different from the methods provided for in this Indenture for such payments or notices. The Issuer shall furnish to the Indenture Trustee a copy of each such agreement and the Indenture Trustee shall cause payments to be made
and notices to be given in accordance with such agreements.

liable, to the extent provided by applicable law, for any unpaid consideration for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. For all purposes of this Indenture, in the performance of any

Trustee of the Issuer, in the exercise of the powers and authority conferred and vested in it, (b) each of the representations, undertakings and agreements herein made on the part of the Issuer is made and intended not as personal
representations, undertakings and agreements by U.S. Bank Trust National Association but is made and intended for the purpose of binding only the Issuer, (c) nothing herein contained shall be construed as creating any liability on U.S. Bank
Trust National Association, individually or personally, to perform any covenant either expressed or implied contained herein of the Issuer, all such liability, if any, being expressly waived by the parties hereto and by any Person claiming by,
through or under the parties hereto, (d) U.S. Bank Trust National Association has not verified and made no investigation as to the accuracy or completeness of any representations and warranties made by the Issuer in this Indenture and
(e) under no circumstances shall U.S. Bank Trust National Association be personally liable for the payment of any indebtedness or expenses of the Issuer or be liable for the breach or failure of any obligation, representation, warranty or
covenant made or undertaken by the Issuer under this Indenture or any other related documents. 
 Section 11.23 PATRIOT Act. The
parties hereto acknowledge that in accordance with the Customer Identification Program (CIP) requirements established under the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of
2001, Title III of Pub. L. 107 56 (signed into law October 26, 2001) and its implementing regulations (collectively, USA PATRIOT Act), the Indenture Trustee in order to help fight the funding of terrorism and money laundering, is required to
obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Indenture Trustee. Each party hereby agrees that it shall provide the Indenture Trustee with such
information as the Indenture Trustee may request from time to time in order to comply with any applicable requirements of the Patriot Act. 

Section 11.24 Beneficial Ownership. Pursuant to applicable law, the Indenture Trustee is required to obtain from the Issuer on or
before closing, and from time to time thereafter, documentation to verify and record information that identifies each person who opens an account. For a non-individual person such as a business entity, a
charity, a trust or legal entity, the Indenture Trustee will ask for documentation to verify the entity’s formation and existence, its financial 

  
 73 













 
statements, licenses, tax identification documents, identification and authorization documents from individuals claiming authority to represent the entity and other relevant documentation and
information (including beneficial owners of such entities). To the fullest extent permitted by applicable law, the Indenture Trustee may conclusively rely on and shall be fully protected and indemnified in relying on, such information received.
Failure to provide such information may result in an inability of the Indenture Trustee to perform its obligations hereunder, which, at the sole option of the Indenture Trustee, may result in the Indenture Trustee’s resignation in accordance
with the terms hereof.

 APPENDIX A 

Additional Representations and Warranties 
  

	1.	 This Indenture creates a valid and continuing “security interest” (as defined in the Relevant UCC) in
the Receivables in favor of the Indenture Trustee, which security interest is prior to all other Liens and is enforceable as such as against creditors of and purchasers from the Issuer. 



 

	2.	 With respect to each Receivable, the Issuer has taken all steps necessary to perfect its security interest
against the related Obligor in the related Financed Vehicle. 


  

	3.	 The Receivables constitute “tangible chattel paper” or “electronic chattel paper” (each as
defined in the Relevant UCC). 


  

	4.	 The Issuer owns and has good and marketable title to the Receivables free and clear of any Lien, claim or
encumbrance of any Person. 


  

	5.	 The Issuer has caused or will cause prior to the Closing Date the filing of all appropriate financing
statements in the proper filing office in the appropriate jurisdictions under applicable law necessary to perfect the security interest in the Receivables granted to the Indenture Trustee under this Indenture. 



 

	6.	 Other than the security interest granted to the Indenture Trustee under the Indenture, the Issuer has not
pledged, assigned, sold, granted a security interest in, or otherwise conveyed any of the Receivables. The Issuer has not authorized the filing of and is not aware of any financing statements against the Seller, the Depositor or the Issuer that
include a description of collateral covering the Receivables other than the financing statements relating to the security interests granted to the Depositor, the Issuer and the Indenture Trustee under the Transaction Documents or any financing
statement that has been terminated. The Issuer is not aware of any judgment or tax lien filings against the Seller, the Depositor or the Issuer. 


  

	7.	 All financing statements filed or to be filed against the Issuer in favor of the Indenture Trustee in
connection herewith describing the Receivables contain a statement 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.”

CarMax Auto Owner Trust 2022-4, a statutory trust organized and existing under the laws of the State
of Delaware (herein referred to as the “Issuer”), for value received, hereby promises to pay to [                ], or its registered assigns, the
principal sum of [                ] DOLLARS OR SUCH LESSER AMOUNT AS IS SET FORTH IN SCHEDULE I or such lesser amount payable on each Distribution Date in an amount
equal to the aggregate amount, if any, payable from the Note Payment Account in respect of principal on the Class A-1 Notes pursuant to Section 2.8 of the Indenture dated as of October 1, 2022
(as amended, supplemented or otherwise modified and in effect from time to time, the “Indenture”) between the Issuer and Wilmington Trust, National Association, a national banking association, as Indenture Trustee (in such capacity,
the “Indenture Trustee”); provided, however, that, if not paid prior to such date, the unpaid principal amount of this Class A-1 Note shall be due and payable on the earlier

terms used but not defined herein are defined in Article I of the Indenture, which also contains rules as to construction that shall be applicable hereto. 

The Issuer shall pay interest on this Class A-1 Note at the rate per annum shown above on each
Distribution Date, until the principal of this Class A-1 Note is paid or made available for payment, on the principal amount of this Class A-1 Note outstanding
on the preceding Distribution Date (after giving effect to all payments of principal made on such preceding Distribution Date), subject to certain limitations contained in Section 3.1 of the Indenture. Interest on this Class A-1 Note shall accrue for each Distribution Date from and including the preceding Distribution Date (or, in the case of the initial Distribution Date or if no interest has been paid, from and including

Class A-1 Note on each Distribution Date shall equal the product of (i) the rate per annum shown above, (ii) the principal amount of this Class A-1
Note outstanding on the preceding Distribution Date (after giving effect to all payments of principal made on such preceding Distribution Date) or, with respect to the initial Distribution Date, on the Closing Date, and (iii) the actual number

 [REVERSE OF CLASS A-1 NOTE] 

This Class A-1 Note is one of a duly authorized issue of Notes of the Issuer, designated as its
4.466% Class A-1 Asset-backed Notes, which, together with the 5.34% Class A-2a Asset-backed Notes, the Benchmark + 0.90%
Class A-2b Asset-backed Notes, the 5.34% Class A-3 Asset-backed Notes, the 5.70% Class A-4 Asset-backed Notes, the
6.01% Class B Asset-backed Notes, the 6.49% Class C Asset-backed Notes and the 8.08% Class D Asset-backed Notes (collectively, the “Notes”), are issued under the Indenture, to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes. The Notes are subject to all terms of the Indenture. 

The Class A-1 Notes are and shall be equally and ratably secured by the collateral pledged as
security therefor as provided in the Indenture. The Class A-2a Notes, the Class A-2b Notes, the Class A-3 Notes,
the Class A-4 Notes, the Class B Notes, the Class C Notes and the Class D Notes are subordinated to the Class A-1 Notes to the extent set forth
in the Indenture and the Sale and Servicing Agreement. 
 As described above, the entire unpaid principal amount of this Class A-1 Note shall be due and payable on the earlier of the Class A-1 Final Distribution Date and the Redemption Date, if any, pursuant to Section 10.1 of the
Indenture. Notwithstanding the foregoing, the entire unpaid principal amount of the Notes, together with accrued and unpaid interest thereon through the date of acceleration, shall be due and payable on the date on which an Event of Default shall
have occurred and be continuing if the Indenture Trustee or the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class have declared the Notes to be immediately due and payable in the manner provided in
Section 5.2 of the Indenture. All principal payments on the Class A-1 Notes shall be made pro rata to the Holders entitled thereto if the Notes have been declared immediately due and payable. 

Payments of interest on this Class A-1 Note due and payable on any Distribution Date, together
with the installment of principal, if any, due and payable on such Distribution Date, to the extent not in full payment of this Class A-1 Note, shall be made by check mailed to the Person whose name
appears as the Holder of this Class A-1 Note (or one or more Predecessor Notes) on the Note Register as of the close of business on the Record Date preceding such Distribution Date or by wire transfer in
immediately available funds to the account designated in writing to the Indenture Trustee by such Person at least five (5) Business Days prior to the related Record Date, except that with respect to
Class A-1 Notes registered on the Record Date in the name of the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.), payments will be made by wire transfer in immediately
available funds to the account designated by such nominee. Such checks shall be mailed to the Person entitled thereto at the address of such Person as it appears on the Note Register as of such Record Date without requiring that this Class A-1 Note be submitted for notation of payment. Any reduction in the principal amount of this Class A-1 Note (or any one or more Predecessor Notes) effected by
any payments made on any Distribution Date shall be binding upon all future Holders of this Class A-1 Note and of any Class A-1 Note issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. If funds are expected to be available, as provided in the Indenture, for payment in full of the then remaining unpaid principal amount of this Class A-1 Note on a Distribution Date, 

  
 Ex. A-1-6 













 
then the Indenture Trustee, in the name of and on behalf of the Issuer, shall notify the Person who was the Holder hereof as of the Record Date preceding such Distribution Date by notice mailed
or transmitted by facsimile prior to such Distribution Date, and the amount then due and payable shall be payable only upon presentation and surrender of this Class A-1 Note at the Indenture
Trustee’s Corporate Trust Office or at the office of the Indenture Trustee’s agent appointed for such purposes located in St. Paul, Minnesota. 

The Issuer shall pay interest on overdue installments of interest at the Class A-1 Rate to the
extent lawful. 
 As provided in the Indenture, the Notes may be redeemed, in whole but not in part, in the manner and to the extent
described in the Indenture and the Sale and Servicing Agreement. 
 As provided in the Indenture, and subject to certain limitations set
forth therein, the transfer of this Class A-1 Note may be registered on the Note Register upon surrender of this Class A-1 Note for registration of transfer at
the office or agency designated by the Issuer pursuant to the Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Indenture Trustee duly executed by, the Holder hereof or such Holder’s
attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor institution” meeting the requirements of the Note Registrar, and thereupon one or more new Class A-1
Notes in any authorized denomination and in the same aggregate principal amount will be issued to the designated transferee or transferees. No service charge will be charged for any registration of transfer or exchange of this Class A-1 Note, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or exchange.

 Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants
and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer or the Indenture Trustee on the Notes or under the Indenture or any certificate or other writing delivered in connection therewith
against (i) the Indenture Trustee or the Owner Trustee, each in its individual capacity, (ii) any holder of a beneficial interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer, director or employee of the
Indenture Trustee or the Owner Trustee, each in its individual capacity, or any holder of a beneficial interest in the Issuer, the Owner Trustee or the Indenture Trustee or any successor or assign of the Indenture Trustee or the Owner Trustee, each
in its individual capacity, except as any such Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided by applicable law, for any unpaid consideration for stock, unpaid
capital contribution for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. 
 Each
Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and agrees that such Noteholder or Note Owner shall not at any time institute against the Depositor or the Issuer, or
join in any institution against the Depositor or the Issuer of, any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under any United States federal or State bankruptcy or similar law in connection with any obligations
relating to the Notes, the Certificates, the Indenture or any of the other Transaction Documents. 

  
 Ex. A-1-7 













 Each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note
Owner, a beneficial interest in this Note, agrees to provide to the Indenture Trustee, any Paying Agent or the Issuer, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the
Noteholder FATCA Information. In addition, each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note Owner, a beneficial interest in this Note, agrees that the Indenture Trustee has the right to withhold any amounts of
interest (properly withholdable under law and without any corresponding gross-up) payable to a Noteholder or holder of an interest in a Note that fails to comply with the requirements of the preceding
sentence. 
 The Issuer has entered into the Indenture and this Class A-1 Note is issued with
the intention that, for federal, State and local income, and franchise tax purposes, the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) will qualify as
indebtedness of the Issuer secured by the Trust Estate. Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, agrees to treat the Notes (other than any Retained Notes held by the
Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) for federal, State and local income, single business and franchise tax purposes as indebtedness of the Issuer. 

Prior to the due presentment for registration of transfer of this Class A-1 Note, the Issuer, the
Indenture Trustee and any agent of the Issuer or the Indenture Trustee may treat the Person in whose name this Class A-1 Note (as of the day of determination or as of such other date as may be specified
in the Indenture) is registered as the owner hereof for all purposes, whether or not this Class A-1 Note shall be overdue, and none of the Issuer, the Indenture Trustee or any such agent shall be affected
by notice to the contrary. 
 The Indenture permits the Owner Trustee, on behalf of the Issuer, and the Indenture Trustee, with certain
exceptions therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture without the consent of the Holders of the Notes. The Indenture also permits the Owner Trustee, on behalf of the Issuer, and the
Indenture Trustee, with certain exceptions as therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture with the consent of the Holders of Notes evidencing not less than 51% of the Note Balance of
the Controlling Class. The Indenture also permits the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class, on behalf of the Holders of all the Notes, to waive compliance by the Issuer with certain provisions of
the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holders of not less than 51% of the Note Balance of the Controlling Class or the Holder of this
Class A-1 Note (or any one or more Predecessor Notes) shall be conclusive and binding on such Holder and on all future Holders of this Class A-1 Note and of
any Class A-1 Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon this Class A-1 Note. 
 The term “Issuer”, as used in this Note, includes any successor to the
Issuer under the Indenture. 

  
 Ex. A-1-8 













 The Indenture permits the Issuer, under certain circumstances, to consolidate or merge with
or into another Person, subject to the rights of the Indenture Trustee and the Holders of Notes under the Indenture. 
 The Notes are
issuable only in registered form in denominations as provided in the Indenture, subject to certain limitations therein set forth. 
 THIS CLASS A-1 NOTE AND THE INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAWS PROVISIONS THEREOF WHICH MAY REQUIRE THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION (OTHER THAN SECTION 5-1401 OF THE NEW
YORK GENERAL OBLIGATIONS LAW). 
 No reference herein to the Indenture, and no provision of this Note or of the Indenture, shall alter or
impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Class A-1 Note at the times, place and rate, and in the coin or currency, herein
prescribed. 
 Anything herein to the contrary notwithstanding, except as expressly provided in the Transaction Documents, none of
Wilmington Trust, National Association, in its individual capacity, U.S. Bank Trust National Association, in its individual capacity, any holder of a beneficial interest in the Issuer, or any of their respective owners, beneficiaries, agents,
officers, directors, employees or successors or assigns shall be personally liable for, nor shall recourse be had to any of them for, the payment of principal of or interest on this Class A-1 Note or the
performance of, or omission to perform, any of the covenants, obligations or indemnifications contained in the Indenture. The Holder of this Note, by its acceptance hereof, agrees that, except as expressly provided in the Transaction Documents, in
the case of an Event of Default under the Indenture, the Holder shall have no claim against any of the foregoing for any deficiency, loss or claim resulting therefrom; provided, however, that nothing contained herein shall be taken to prevent
recourse to, or enforcement against, the assets of the Issuer for any and all liabilities, obligations and undertakings contained in the Indenture or in this Class A-1 Note.

principal sum of [                ] DOLLARS OR SUCH LESSER AMOUNT AS IS SET FORTH IN SCHEDULE I or such lesser amount payable on each Distribution Date in an amount
equal to the aggregate amount, if any, payable from the Note Payment Account in respect of principal on the Class A-2a Notes pursuant to Section 2.8 of the Indenture dated as of October 1, 2022
(as amended, supplemented or otherwise modified and in effect from time to time, the “Indenture”) between the Issuer and Wilmington Trust, National Association, a national banking association, as Indenture Trustee (in such capacity,
the “Indenture Trustee”); provided, however, that principal of this Class A-2a Note will not be due and payable until the
Class A-1 Notes have been paid in full; and, provided further, that, if not paid prior to such date, the unpaid principal amount of this
Class A-2a Note shall be due and payable on the earlier of the December 2025 Distribution Date (the “Class A-2a Final Distribution
Date”) and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture. Capitalized terms used but not defined herein are defined in Article I of the Indenture, which also contains rules as to construction that shall be
applicable hereto. 
 The Issuer shall pay interest on this Class A-2a Note at the rate per
annum shown above on each Distribution Date, until the principal of this Class A-2a Note is paid or made available for payment, on the principal amount of this
Class A-2a Note outstanding on the preceding Distribution Date (after giving effect to all payments of principal made on such preceding Distribution Date), subject to certain limitations contained in
Section 3.1 of the Indenture. Interest on this Class A-2a Note shall accrue for each Distribution Date from and including the 15th day of the preceding month (or, in the case of the initial
Distribution Date or if no interest has been paid, from and including the Closing Date) to but excluding the 15th day of the month in which such Distribution Date occurs. Interest shall be computed on the basis of a
360-day year consisting of twelve 30-day months. Interest on this Class A-2a Note on each Distribution Date shall equal

month in which such Distribution Date occurs, assuming each month has 30 days, divided by 360) of the product of (i) the rate per annum shown above and (ii) the principal amount of this
Class A-2a Note outstanding as of the Closing Date (in the case of the first Distribution Date) or on the preceding Distribution Date (after giving effect to all payments of principal made on such
preceding Distribution Date). The principal of and interest on this Class A-2a Note shall be paid in the manner specified on the reverse hereof.

commencing on November 15, 2022. 
 The principal of and interest on this Class A-2a Note
are payable in such coin or currency of the United States as at the time of payment is legal tender for payment of public and private debts. All payments made by the Issuer with respect to this Class A-2a
Note shall be applied first to interest due and payable on this Class A-2a Note as provided above and then to the unpaid principal of this Class A-2a Note.

 Reference is hereby made to the further provisions of this Class A-2a Note set forth on the
reverse hereof, which further provisions shall for all purposes have the same effect as if fully set forth on the face of this Class A-2a Note.

 [REVERSE OF CLASS A-2a NOTE] 

This Class A-2a Note is one of a duly authorized issue of Notes of the Issuer, designated as its
5.34% Class A-2a Asset-backed Notes, which, together with the 4.466% Class A-1 Asset-backed Notes, the Benchmark + 0.90%
Class A-2b Asset-backed Notes, the 5.34% Class A-3 Asset-backed Notes, the 5.70% Class A-4 Asset-backed Notes, the
6.01% Class B Asset-backed Notes, the 6.49% Class C Asset-backed Notes and the 8.08% Class D Asset-backed Notes (collectively, the “Notes”), are issued under the Indenture, to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes. The Notes are subject to all terms of the Indenture. 

The Class A-2a Notes are and shall be equally and ratably secured by the collateral pledged as
security therefor as provided in the Indenture. The Class A-2a Notes are subordinated to the Class A-1 Notes to the extent set forth in the Indenture and the
Sale and Servicing Agreement. The Class A-3 Notes, the Class A-4 Notes, the Class B Notes, the Class C Notes and the Class D Notes are
subordinated to the Class A-2a Notes to the extent set forth in the Indenture and the Sale and Servicing Agreement. The Class A-2a Notes and the Class A-2b Notes are pari passu to the extent set forth in the Indenture and the Sale and Servicing Agreement. 

As described above, the entire unpaid principal amount of this Class A-2a Note shall be due and
payable on the earlier of the Class A-2a Final Distribution Date and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture. Notwithstanding the foregoing, the entire unpaid principal
amount of the Notes, together with accrued and unpaid interest thereon through the date of acceleration, shall be due and payable on the date on which an Event of Default shall have occurred and be continuing if the Indenture Trustee or the Holders
of Notes evidencing not less than 51% of the Note Balance of the Controlling Class have declared the Notes to be immediately due and payable in the manner provided in Section 5.2 of the Indenture. All principal payments on the Class A-2a Notes shall be made pro rata to the Holders entitled thereto if the Notes have been declared immediately due and payable. 

Payments of interest on this Class A-2a Note due and payable on any Distribution Date, together
with the installment of principal, if any, due and payable on such Distribution Date, to the extent not in full payment of this Class A-2a Note, shall be made by check mailed to the Person whose name
appears as the Holder of this Class A-2a Note (or one or more Predecessor Notes) on the Note Register as of the close of business on the Record Date preceding such Distribution Date or by wire transfer in
immediately available funds to the account designated in writing to the Indenture Trustee by such Person at least five (5) Business Days prior to the related Record Date, except that with respect to
Class A-2a Notes registered on the Record Date in the name of the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.), payments will be made by wire transfer in immediately
available funds to the account designated by such nominee. Such checks shall be mailed to the Person entitled thereto at the address of such Person as it appears on the Note Register as of such Record Date without requiring that this Class A-2a Note be submitted for notation of payment. Any reduction in the principal amount of this Class A-2a Note (or any one or more Predecessor Notes) effected
by any payments made on any Distribution Date shall be binding upon all future Holders of this Class A-2a Note and of any Class A-2a Note issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not 

  
 Ex. A-2a-6 













 
noted hereon. If funds are expected to be available, as provided in the Indenture, for payment in full of the then remaining unpaid principal amount of this
Class A-2a Note on a Distribution Date, then the Indenture Trustee, in the name of and on behalf of the Issuer, shall notify the Person who was the Holder hereof as of the Record Date preceding such
Distribution Date by notice mailed or transmitted by facsimile prior to such Distribution Date, and the amount then due and payable shall be payable only upon presentation and surrender of this Class A-2a
Note at the Indenture Trustee’s Corporate Trust Office or at the office of the Indenture Trustee’s agent appointed for such purposes located in St. Paul, Minnesota. 

The Issuer shall pay interest on overdue installments of interest at the Class A-2a Rate to the
extent lawful. 
 As provided in the Indenture, the Notes may be redeemed, in whole but not in part, in the manner and to the extent
described in the Indenture and the Sale and Servicing Agreement. 
 As provided in the Indenture, and subject to certain limitations set
forth therein, the transfer of this Class A-2a Note may be registered on the Note Register upon surrender of this Class A-2a Note for registration of transfer
at the office or agency designated by the Issuer pursuant to the Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Indenture Trustee duly executed by, the Holder hereof or such Holder’s
attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor institution” meeting the requirements of the Note Registrar, and thereupon one or more new
Class A-2a Notes in any authorized denomination and in the same aggregate principal amount will be issued to the designated transferee or transferees. No service charge will be charged for any
registration of transfer or exchange of this Class A-2a Note, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection
with any such registration of transfer or exchange. 
 Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note
Owner, a beneficial interest in a Note, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer or the Indenture Trustee on the Notes or under the Indenture or any certificate or
other writing delivered in connection therewith against (i) the Indenture Trustee or the Owner Trustee, each in its individual capacity, (ii) any holder of a beneficial interest in the Issuer or (iii) any partner, owner, beneficiary,
agent, officer, director or employee of the Indenture Trustee or the Owner Trustee, each in its individual capacity, or any holder of a beneficial interest in the Issuer, the Owner Trustee or the Indenture Trustee or any successor or assign of the
Indenture Trustee or the Owner Trustee, each in its individual capacity, except as any such Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided by applicable law, for
any unpaid consideration for stock, unpaid capital contribution for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. 

Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and
agrees that such Noteholder or Note Owner shall not at any time institute against the Depositor or the Issuer, or join in any institution against the Depositor or the Issuer of, any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under any United States federal or State bankruptcy or similar law in connection with any obligations relating to the Notes, the Certificates, the Indenture or any of the other Transaction Documents. 

  
 Ex. A-2a-7 













 Each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note
Owner, a beneficial interest in this Note, agrees to provide to the Indenture Trustee, any Paying Agent or the Issuer, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the
Noteholder FATCA Information. In addition, each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note Owner, a beneficial interest in this Note, agrees that the Indenture Trustee has the right to withhold any amounts of
interest (properly withholdable under law and without any corresponding gross-up) payable to a Noteholder or holder of an interest in a Note that fails to comply with the requirements of the preceding
sentence. 
 The Issuer has entered into the Indenture and this Class A-2a Note is issued with
the intention that, for federal, State and local income, and franchise tax purposes, the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) will qualify as
indebtedness of the Issuer secured by the Trust Estate. Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, agrees to treat the Notes (other than any Retained Notes held by the

principal sum of [                ] DOLLARS OR SUCH LESSER AMOUNT AS IS SET FORTH IN SCHEDULE I or such lesser amount payable on each Distribution Date in an amount
equal to the aggregate amount, if any, payable from the Note Payment Account in respect of principal on the Class A-2b Notes pursuant to Section 2.8 of the Indenture dated as of October 1, 2022
(as amended, supplemented or otherwise modified and in effect from time to time, the “Indenture”) between the Issuer and Wilmington Trust, National Association, a national banking association, as Indenture Trustee (in such capacity,
the “Indenture Trustee”); provided, however, that principal of this Class A-2b Note will not be due and payable until the
Class A-1 Notes have been paid in full; and, provided further, that, if not paid prior to such date, the unpaid principal amount of this
Class A-2b Note shall be due and payable on the earlier of the December 2025 Distribution Date (the “Class A-2b Final Distribution
Date”) and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture. Capitalized terms used but not defined herein are defined in Article I of the Indenture, which also contains rules as to construction that shall be
applicable hereto. 
 The Issuer shall pay interest on this Class A-2b Note at a rate based on
the Benchmark determined in accordance with the terms of the Indenture for the related Accrual Period plus 0.90% per annum on each Distribution Date (provided, that for any Accrual Period for which the sum of Benchmark + 0.90% is less than 0.00%,
the interest rate shall be deemed to be 0.00%), until the principal of this Class A-2b Note is paid or made available for payment, on the principal amount of this
Class A-2b Note outstanding on the preceding Distribution Date (after giving effect to all payments of principal made on such preceding Distribution Date), subject to certain limitations contained in
Section 3.1 of the Indenture. Interest on this Class A-2b Note shall accrue for each Distribution Date from and including the preceding Distribution Date (or, in the case of the initial Distribution
Date or if no interest has been paid, from and including the Closing Date) to but 

  
 Ex. A-2b-3 













 
excluding such Distribution Date. Interest shall be computed on the basis of actual days elapsed and a 360-day year. Interest on this Class A-2b Note on each Distribution Date shall equal one-twelfth of the product of (i) the rate per annum described above and (ii) the principal amount of this
Class A-2b Note outstanding on the preceding Distribution Date (after giving effect to all payments of principal made on such preceding Distribution Date) or, with respect to the initial Distribution
Date, on the Closing Date and (iii) the actual number of days in the applicable interest period divided by 360. The principal of and interest on this Class A-2b Note shall be paid in the manner
specified on the reverse hereof. 
 “Distribution Date” means the 15th day of each month or, if such 15th day is not a
Business Day, the following Business Day, commencing on November 15, 2022. 
 The principal of and interest on this Class A-2b Note are payable in such coin or currency of the United States as at the time of payment is legal tender for payment of public and private debts. All payments made by the Issuer with respect to this Class A-2b Note shall be applied first to interest due and payable on this Class A-2b Note as provided above and then to the unpaid principal of this Class A-2b Note. 
 Reference is hereby made to the further provisions of this Class A-2b Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if fully set forth on the face of this
Class A-2b Note. 
 Unless the certificate of authentication hereon has been executed by an
authorized officer of the Indenture Trustee, by manual or facsimile signature, this Class A-2b Note shall not entitle the Holder hereof to any benefit under the Indenture or be valid for any purpose.

 [REVERSE OF CLASS A-2b NOTE] 

This Class A-2b Note is one of a duly authorized issue of Notes of the Issuer, designated as its
Benchmark + 0.90% Class A-2b Asset-backed Notes, which, together with the 4.466% Class A-1 Asset-backed Notes, the 5.34%
Class A-2a Asset-backed Notes, the 5.34% Class A-3 Asset-backed Notes, the 5.70% Class A-4 Asset-backed Notes, the
6.01% Class B Asset-backed Notes, the 6.49% Class C Asset-backed Notes and the 8.08% Class D Asset-backed Notes (collectively, the “Notes”), are issued under the Indenture, to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes. The Notes are subject to all terms of the Indenture. 

The Class A-2b Notes are and shall be equally and ratably secured by the collateral pledged as
security therefor as provided in the Indenture. The Class A-2b Notes are subordinated to the Class A-1 Notes to the extent set forth in the Indenture and the
Sale and Servicing Agreement. The Class A-3 Notes, the Class A-4 Notes, the Class B Notes, the Class C Notes and the Class D Notes are
subordinated to the Class A-2b Notes to the extent set forth in the Indenture and the Sale and Servicing Agreement. The Class A-2b Notes and the Class A-2a Notes are pari passu to the extent set forth in the Indenture and the Sale and Servicing Agreement. 

As described above, the entire unpaid principal amount of this Class A-2b Note shall be due and
payable on the earlier of the Class A-2b Final Distribution Date and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture. Notwithstanding the foregoing, the entire unpaid principal
amount of the Notes, together with accrued and unpaid interest thereon through the date of acceleration, shall be due and payable on the date on which an Event of Default shall have occurred and be continuing if the Indenture Trustee or the Holders
of Notes evidencing not less than 51% of the Note Balance of the Controlling Class have declared the Notes to be immediately due and payable in the manner provided in Section 5.2 of the Indenture. All principal payments on the Class A-2b Notes shall be made pro rata to the Holders entitled thereto if the Notes have been declared immediately due and payable. 

Payments of interest on this Class A-2b Note due and payable on any Distribution Date, together
with the installment of principal, if any, due and payable on such Distribution Date, to the extent not in full payment of this Class A-2b Note, shall be made by check mailed to the Person whose name
appears as the Holder of this Class A-2b Note (or one or more Predecessor Notes) on the Note Register as of the close of business on the Record Date preceding such Distribution Date or by wire transfer in
immediately available funds to the account designated in writing to the Indenture Trustee by such Person at least five (5) Business Days prior to the related Record Date, except that with respect to
Class A-2b Notes registered on the Record Date in the name of the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.), payments will be made by wire transfer in immediately
available funds to the account designated by such nominee. Such checks shall be mailed to the Person entitled thereto at the address of such Person as it appears on the Note Register as of such Record Date without requiring that this Class A-2b Note be submitted for notation of payment. Any reduction in the principal amount of this Class A-2b Note (or any one or more Predecessor Notes) effected
by any payments made on any Distribution Date shall be binding upon all future Holders of this Class A-2b Note and of any Class A-2b Note issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not 

  
 Ex. A-2b-6 













 
noted hereon. If funds are expected to be available, as provided in the Indenture, for payment in full of the then remaining unpaid principal amount of this
Class A-2b Note on a Distribution Date, then the Indenture Trustee, in the name of and on behalf of the Issuer, shall notify the Person who was the Holder hereof as of the Record Date preceding such
Distribution Date by notice mailed or transmitted by facsimile prior to such Distribution Date, and the amount then due and payable shall be payable only upon presentation and surrender of this Class A-2b
Note at the Indenture Trustee’s Corporate Trust Office or at the office of the Indenture Trustee’s agent appointed for such purposes located in St. Paul, Minnesota. 

The Issuer shall pay interest on overdue installments of interest at the Class A-2b Rate to the
extent lawful. 
 As provided in the Indenture, the Notes may be redeemed, in whole but not in part, in the manner and to the extent
described in the Indenture and the Sale and Servicing Agreement. 
 As provided in the Indenture, and subject to certain limitations set
forth therein, the transfer of this Class A-2b Note may be registered on the Note Register upon surrender of this Class A-2b Note for registration of transfer
at the office or agency designated by the Issuer pursuant to the Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Indenture Trustee duly executed by, the Holder hereof or such Holder’s
attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor institution” meeting the requirements of the Note Registrar, and thereupon one or more new
Class A-2b Notes in any authorized denomination and in the same aggregate principal amount will be issued to the designated transferee or transferees. No service charge will be charged for any
registration of transfer or exchange of this Class A-2b Note, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection
with any such registration of transfer or exchange. 
 Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note
Owner, a beneficial interest in a Note, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer or the Indenture Trustee on the Notes or under the Indenture or any certificate or
other writing delivered in connection therewith against (i) the Indenture Trustee or the Owner Trustee, each in its individual capacity, (ii) any holder of a beneficial interest in the Issuer or (iii) any partner, owner, beneficiary,
agent, officer, director or employee of the Indenture Trustee or the Owner Trustee, each in its individual capacity, or any holder of a beneficial interest in the Issuer, the Owner Trustee or the Indenture Trustee or any successor or assign of the
Indenture Trustee or the Owner Trustee, each in its individual capacity, except as any such Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided by applicable law, for
any unpaid consideration for stock, unpaid capital contribution for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. 

Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and
agrees that such Noteholder or Note Owner shall not at any time institute against the Depositor or the Issuer, or join in any institution against the Depositor or the Issuer of, any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under any United States federal or State bankruptcy or similar law in connection with any obligations relating to the Notes, the Certificates, the Indenture or any of the other Transaction Documents. 

  
 Ex. A-2b-7 













 Each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note
Owner, a beneficial interest in this Note, agrees to provide to the Indenture Trustee, any Paying Agent or the Issuer, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the
Noteholder FATCA Information. In addition, each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note Owner, a beneficial interest in this Note, agrees that the Indenture Trustee has the right to withhold any amounts of
interest (properly withholdable under law and without any corresponding gross-up) payable to a Noteholder or holder of an interest in a Note that fails to comply with the requirements of the preceding
sentence. 
 The Issuer has entered into the Indenture and this Class A-2b Note is issued with
the intention that, for federal, State and local income, and franchise tax purposes, the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) will qualify as
indebtedness of the Issuer secured by the Trust Estate. Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, agrees to treat the Notes (other than any Retained Notes held by the
Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) for federal, State and local income, single business and franchise tax purposes as indebtedness of the Issuer. 

Prior to the due presentment for registration of transfer of this Class A-2b Note, the Issuer,
the Indenture Trustee and any agent of the Issuer or the Indenture Trustee may treat the Person in whose name this Class A-2b Note (as of the day of determination or as of such other date as may be
specified in the Indenture) is registered as the owner hereof for all purposes, whether or not this Class A-2b Note shall be overdue, and none of the Issuer, the Indenture Trustee or any such agent shall
be affected by notice to the contrary. 
 The Indenture permits the Owner Trustee, on behalf of the Issuer, and the Indenture Trustee, with
certain exceptions therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture without the consent of the Holders of the Notes. The Indenture also permits the Owner Trustee, on behalf of the Issuer,
and the Indenture Trustee, with certain exceptions as therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture with the consent of the Holders of Notes evidencing not less than 51% of the Note
Balance of the Controlling Class. The Indenture also permits the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class, on behalf of the Holders of all the Notes, to waive compliance by the Issuer with certain
provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holders of not less than 51% of the Note Balance of the Controlling Class or the Holder of this Class A-2b Note (or any one or more Predecessor Notes) shall be conclusive and binding on such Holder and on all future Holders of this Class A-2b Note and of any Class A-2b Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon this
Class A-2b Note. 

  
 Ex. A-2b-8 













 The term “Issuer”, as used in this Note, includes any successor to the Issuer

subject to the rights of the Indenture Trustee and the Holders of Notes under the Indenture. 
 The Notes are issuable only in registered
form in denominations as provided in the Indenture, subject to certain limitations therein set forth. 
 THIS
CLASS A-2B NOTE AND THE INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAWS PROVISIONS THEREOF WHICH MAY REQUIRE THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION (OTHER THAN SECTION 5-1401
OF THE NEW YORK GENERAL OBLIGATIONS LAW).

alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Class A-2b Note at the times, place and rate, and in the coin or currency,
herein prescribed. 
 Anything herein to the contrary notwithstanding, except as expressly provided in the Transaction Documents, none of
Wilmington Trust, National Association, in its individual capacity, U.S. Bank Trust National Association, in its individual capacity, any holder of a beneficial interest in the Issuer, or any of their respective owners, beneficiaries, agents,
officers, directors, employees or successors or assigns shall be personally liable for, nor shall recourse be had to any of them for, the payment of principal of or interest on this Class A-2b Note or the
performance of, or omission to perform, any of the covenants, obligations or indemnifications contained in the Indenture. The Holder of this Note, by its acceptance hereof, agrees that, except as expressly provided in the Transaction Documents, in
the case of an Event of Default under the Indenture, the Holder shall have no claim against any of the foregoing for any deficiency, loss or claim resulting therefrom; provided, however, that nothing contained herein shall be taken to prevent
recourse to, or enforcement against, the assets of the Issuer for any and all liabilities, obligations and undertakings contained in the Indenture or in this Class A-2b Note.

5.34% CLASS A-3 ASSET-BACKED NOTE 

CarMax Auto Owner Trust 2022-4, a statutory trust organized and existing under the laws of the State
of Delaware (herein referred to as the “Issuer”), for value received, hereby promises to pay to [                ], or its registered assigns, the
principal sum of [                ] DOLLARS OR SUCH LESSER AMOUNT AS IS SET FORTH IN SCHEDULE I or such lesser amount payable on each Distribution Date in an amount
equal to the aggregate amount, if any, payable from the Note Payment Account in respect of principal on the Class A-3 Notes pursuant to Section 2.8 of the Indenture dated as of October 1, 2022
(as amended, supplemented or otherwise modified and in effect from time to time, the “Indenture”) between the Issuer and Wilmington Trust, National Association, a national banking association, as Indenture Trustee (in such capacity,
the “Indenture Trustee”); provided, however, that, except under certain limited circumstances described in the Indenture, principal of this Class A-3 Note will not be due
and payable until the Class A-1 Notes, the Class A-2a Notes and the Class A-2b Notes have been paid in full; and,
provided further, that, if not paid prior to such date, the unpaid principal amount of this Class A-3 Note shall be due and payable on the earlier of the August 2027 Distribution Date (the
“Class A-3 Final Distribution Date”) and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture. Capitalized terms used but not defined herein are
defined in Article I of the Indenture, which also contains rules as to construction that shall be applicable hereto. 
 The Issuer shall pay
interest on this Class A-3 Note at the rate per annum shown above on each Distribution Date, until the principal of this Class A-3 Note is paid or made
available for payment, on the principal amount of this Class A-3 Note outstanding on the preceding Distribution Date (after giving effect to all payments of principal made on such preceding Distribution
Date), subject to certain limitations contained in Section 3.1 of the Indenture. Interest on this Class A-3 Note shall accrue for each Distribution Date from and including the 15th day of the
preceding month (or, in the case of the initial Distribution Date or if no interest has been paid, from and including the Closing Date) to but excluding the 15th day of the month in which such Distribution Date occurs. Interest shall be computed on
the basis of a 360-day year consisting of twelve 30-

  
 Ex. A-3-3 













 
day months. Interest on this Class A-3 Note on each Distribution Date shall equal one-twelfth (or, in the case
of the first Distribution Date, the number of days from and including the Closing Date to but excluding the 15th day of the month in which such Distribution Date occurs, assuming each month has 30 days, divided by 360) of the product of (i) the
rate per annum shown above and (ii) the principal amount of this Class A-3 Note outstanding as of the Closing Date (in the case of the first Distribution Date) or on the preceding Distribution Date
(after giving effect to all payments of principal made on such preceding Distribution Date). The principal of and interest on this Class A-3 Note shall be paid in the manner specified on the reverse
hereof. 
 “Distribution Date” means the 15th day of each month or, if such 15th day is not a Business Day, the following
Business Day, commencing on November15, 2022. 
 The principal of and interest on this
Class A-3 Note are payable in such coin or currency of the United States as at the time of payment is legal tender for payment of public and private debts. All payments made by the Issuer with respect to
this Class A-3 Note shall be applied first to interest due and payable on this Class A-3 Note as provided above and then to the unpaid principal of this Class A-3 Note. 
 Reference is hereby made to the further provisions of this Class A-3 Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if fully set forth on the face of this
Class A-3 Note. 
 Unless the certificate of authentication hereon has been executed by an
authorized officer of the Indenture Trustee, by manual or facsimile signature, this Class A-3 Note shall not entitle the Holder hereof to any benefit under the Indenture or be valid for any purpose.

 [REVERSE OF CLASS A-3 NOTE] 

This Class A-3 Note is one of a duly authorized issue of Notes of the Issuer, designated as its
5.34% Class A-3 Asset-backed Notes, which, together with the 4.466% Class A-1 Asset-backed Notes, the 5.34%
Class A-2a Asset-backed Notes, the Benchmark + 0.90% Class A-2b Asset-backed Notes, the 5.70% Class A-4
Asset-backed Notes, the 6.01% Class B Asset-backed Notes, the 6.49% Class C Asset-backed Notes and the 8.08% Class D Asset-backed Notes (collectively, the “Notes”), are issued under the Indenture, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes. The Notes are subject to all terms of the
Indenture. 
 The Class A-3 Notes are and shall be equally and ratably secured by the
collateral pledged as security therefor as provided in the Indenture. The Class A-3 Notes are subordinated to the Class A-1 Notes, the Class A-2a Notes and the Class A-2b Notes to the extent set forth in the Indenture and the Sale and Servicing Agreement. The
Class A-4 Notes, the Class B Notes, the Class C Notes and the Class D Notes are subordinated to the Class A-3 Notes to the extent set forth in
the Indenture and the Sale and Servicing Agreement. 
 As described above, the entire unpaid principal amount of this Class A-3 Note shall be due and payable on the earlier of the Class A-3 Final Distribution Date and the Redemption Date, if any, pursuant to Section 10.1 of the
Indenture. Notwithstanding the foregoing, the entire unpaid principal amount of the Notes, together with accrued and unpaid interest thereon through the date of acceleration, shall be due and payable on the date on which an Event of Default shall
have occurred and be continuing if the Indenture Trustee or the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class have declared the Notes to be immediately due and payable in the manner provided in
Section 5.2 of the Indenture. All principal payments on the Class A-3 Notes shall be made pro rata to the Holders entitled thereto if the Notes have been declared immediately due and payable. 

Payments of interest on this Class A-3 Note due and payable on any Distribution Date, together
with the installment of principal, if any, due and payable on such Distribution Date, to the extent not in full payment of this Class A-3 Note, shall be made by check mailed to the Person whose name
appears as the Holder of this Class A-3 Note (or one or more Predecessor Notes) on the Note Register as of the close of business on the Record Date preceding such Distribution Date or by wire transfer in
immediately available funds to the account designated in writing to the Indenture Trustee by such Person at least five (5) Business Days prior to the related Record Date, except that with respect to
Class A-3 Notes registered on the Record Date in the name of the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.), payments will be made by wire transfer in immediately
available funds to the account designated by such nominee. Such checks shall be mailed to the Person entitled thereto at the address of such Person as it appears on the Note Register as of such Record Date without requiring that this Class A-3 Note be submitted for notation of payment. Any reduction in the principal amount of this Class A-3 Note (or any one or more Predecessor Notes) effected by
any payments made on any Distribution Date shall be binding upon all future Holders of this Class A-3 Note and of any Class A-3 Note issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. If funds are expected to be available, as provided in the Indenture, for payment in 

  
 Ex. A-3-6 













 
full of the then remaining unpaid principal amount of this Class A-3 Note on a Distribution Date, then the Indenture Trustee, in the name of and on
behalf of the Issuer, shall notify the Person who was the Holder hereof as of the Record Date preceding such Distribution Date by notice mailed or transmitted by facsimile prior to such Distribution Date, and the amount then due and payable shall be
payable only upon presentation and surrender of this Class A-3 Note at the Indenture Trustee’s Corporate Trust Office or at the office of the Indenture Trustee’s agent appointed for such
purposes located in St. Paul, Minnesota. 
 The Issuer shall pay interest on overdue installments of interest at the Class A-3 Rate to the extent lawful. 
 As provided in the Indenture, the Notes may be redeemed, in
whole but not in part, in the manner and to the extent described in the Indenture and the Sale and Servicing Agreement. 
 As provided in
the Indenture, and subject to certain limitations set forth therein, the transfer of this Class A-3 Note may be registered on the Note Register upon surrender of this
Class A-3 Note for registration of transfer at the office or agency designated by the Issuer pursuant to the Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Indenture Trustee duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor institution” meeting the requirements of the Note
Registrar, and thereupon one or more new Class A-3 Notes in any authorized denomination and in the same aggregate principal amount will be issued to the designated transferee or transferees. No service
charge will be charged for any registration of transfer or exchange of this Class A-3 Note, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any such registration of transfer or exchange. 
 Each Noteholder or Note Owner, by its acceptance of a
Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer or the Indenture Trustee on the Notes or under the
Indenture or any certificate or other writing delivered in connection therewith against (i) the Indenture Trustee or the Owner Trustee, each in its individual capacity, (ii) any holder of a beneficial interest in the Issuer or
(iii) any partner, owner, beneficiary, agent, officer, director or employee of the Indenture Trustee or the Owner Trustee, each in its individual capacity, or any holder of a beneficial interest in the Issuer, the Owner Trustee or the Indenture
Trustee or any successor or assign of the Indenture Trustee or the Owner Trustee, each in its individual capacity, except as any such Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to
the extent provided by applicable law, for any unpaid consideration for stock, unpaid capital contribution for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. 

Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and
agrees that such Noteholder or Note Owner shall not at any time institute against the Depositor or the Issuer, or join in any institution against the Depositor or the Issuer of, any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under any United States federal or State bankruptcy or similar law in connection with any obligations relating to the Notes, the Certificates, the Indenture or any of the other Transaction Documents. 

  
 Ex. A-3-7 













 Each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note
Owner, a beneficial interest in this Note, agrees to provide to the Indenture Trustee, any Paying Agent or the Issuer, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the
Noteholder FATCA Information. In addition, each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note Owner, a beneficial interest in this Note, agrees that the Indenture Trustee has the right to withhold any amounts of
interest (properly withholdable under law and without any corresponding gross-up) payable to a Noteholder or holder of an interest in a Note that fails to comply with the requirements of the preceding
sentence. 
 The Issuer has entered into the Indenture and this Class A-3 Note is issued with
the intention that, for federal, State and local income, and franchise tax purposes, the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) will qualify as
indebtedness of the Issuer secured by the Trust Estate. Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, agrees to treat the Notes (other than any Retained Notes held by the
Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) for federal, State and local income, single business and franchise tax purposes as indebtedness of the Issuer. 

Prior to the due presentment for registration of transfer of this Class A-3 Note, the Issuer, the
Indenture Trustee and any agent of the Issuer or the Indenture Trustee may treat the Person in whose name this Class A-3 Note (as of the day of determination or as of such other date as may be specified
in the Indenture) is registered as the owner hereof for all purposes, whether or not this Class A-3 Note shall be overdue, and none of the Issuer, the Indenture Trustee or any such agent shall be affected
by notice to the contrary. 
 The Indenture permits the Owner Trustee, on behalf of the Issuer, and the Indenture Trustee, with certain
exceptions therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture without the consent of the Holders of the Notes. The Indenture also permits the Owner Trustee, on behalf of the Issuer, and the
Indenture Trustee, with certain exceptions as therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture with the consent of the Holders of Notes evidencing not less than 51% of the Note Balance of
the Controlling Class. The Indenture also permits the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class, on behalf of the Holders of all the Notes, to waive compliance by the Issuer with certain provisions of
the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holders of not less than 51% of the Note Balance of the Controlling Class or the Holder of this
Class A-3 Note (or any one or more Predecessor Notes) shall be conclusive and binding on such Holder and on all future Holders of this Class A-3 Note and of
any Class A-3 Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon this Class A-3 Note. 

  
 Ex. A-3-8 













 The term “Issuer”, as used in this Note, includes any successor to the Issuer
under the Indenture. 
 The Indenture permits the Issuer, under certain circumstances, to consolidate or merge with or into another Person,
subject to the rights of the Indenture Trustee and the Holders of Notes under the Indenture. 
 The Notes are issuable only in registered
form in denominations as provided in the Indenture, subject to certain limitations therein set forth. 
 THIS
CLASS A-3 NOTE AND THE INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAWS PROVISIONS THEREOF WHICH MAY REQUIRE THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION (OTHER THAN SECTION 5-1401
OF THE NEW YORK GENERAL OBLIGATIONS LAW). 
 No reference herein to the Indenture, and no provision of this Note or of the Indenture, shall
alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Class A-3 Note at the times, place and rate, and in the coin or currency,
herein prescribed. 
 Anything herein to the contrary notwithstanding, except as expressly provided in the Transaction Documents, none of
Wilmington Trust, National Association, in its individual capacity, U.S. Bank Trust National Association, in its individual capacity, any holder of a beneficial interest in the Issuer, or any of their respective owners, beneficiaries, agents,
officers, directors, employees or successors or assigns shall be personally liable for, nor shall recourse be had to any of them for, the payment of principal of or interest on this Class A-3 Note or the
performance of, or omission to perform, any of the covenants, obligations or indemnifications contained in the Indenture. The Holder of this Note, by its acceptance hereof, agrees that, except as expressly provided in the Transaction Documents, in
the case of an Event of Default under the Indenture, the Holder shall have no claim against any of the foregoing for any deficiency, loss or claim resulting therefrom; provided, however, that nothing contained herein shall be taken to prevent
recourse to, or enforcement against, the assets of the Issuer for any and all liabilities, obligations and undertakings contained in the Indenture or in this Class A-3 Note.

principal sum of [                ] DOLLARS OR SUCH LESSER AMOUNT AS IS SET FORTH IN SCHEDULE I or such lesser amount payable on each Distribution Date in an amount
equal to the aggregate amount, if any, payable from the Note Payment Account in respect of principal on the Class A-4 Notes pursuant to Section 2.8 of the Indenture dated as of October 1, 2022
(as amended, supplemented or otherwise modified and in effect from time to time, the “Indenture”) between the Issuer and Wilmington Trust, National Association, a national banking association, as Indenture Trustee (in such capacity,
the “Indenture Trustee”); provided, however, that, except under certain limited circumstances described in the Indenture, principal of this Class A-4 Note will not be due
and payable until the Class A-1 Notes, the Class A-2a Notes, the Class A-2b Notes and the Class A-3 Notes have been paid in full; and, provided further, that, if not paid prior to such date, the unpaid principal amount of this Class A-4 Note
shall be due and payable on the earlier of the July 2028 Distribution Date (the “Class A-4 Final Distribution Date”) and the Redemption Date, if any, pursuant to

The Issuer shall pay interest on this Class A-4 Note at the rate per annum shown above on each

on the preceding Distribution Date (after giving effect to all payments of principal made on such preceding Distribution Date), subject to certain limitations contained in Section 3.1 of the Indenture. Interest on this Class A-4 Note shall accrue for each Distribution Date from and including the 15th day of the preceding month (or, in the case of the initial Distribution Date or if no interest has been paid, from and

 [REVERSE OF CLASS A-4 NOTE] 

This Class A-4 Note is one of a duly authorized issue of Notes of the Issuer, designated as its
5.70% Class A-4 Asset-backed Notes, which, together with the 4.466% Class A-1 Asset-backed Notes, the 5.34%
Class A-2a Asset-backed Notes, the Benchmark + 0.90% Class A-2b Asset-backed Notes, the 5.34% Class A-3
Asset-backed Notes, the 6.01% Class B Asset-backed Notes, the 6.49% Class C Asset-backed Notes and the 8.08% Class D Asset-backed Notes (collectively, the “Notes”), are issued under the Indenture, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes. The Notes are subject to all terms of the
Indenture. 
 The Class A-4 Notes are and shall be equally and ratably secured by the
collateral pledged as security therefor as provided in the Indenture. The Class A-4 Notes are subordinated to the Class A-1 Notes, the Class A-2a Notes, the Class A-2b Notes and the Class A-3 Notes to the extent set forth in the Indenture and the Sale and
Servicing Agreement. The Class B Notes, the Class C Notes and the Class D Notes are subordinated to the Class A-4 Notes to the extent set forth in the Indenture and the Sale and Servicing
Agreement. 
 As described above, the entire unpaid principal amount of this Class A-4 Note
shall be due and payable on the earlier of the Class A-4 Final Distribution Date and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture. Notwithstanding the foregoing, the entire
unpaid principal amount of the Notes, together with accrued and unpaid interest thereon through the date of acceleration, shall be due and payable on the date on which an Event of Default shall have occurred and be continuing if the Indenture
Trustee or the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class have declared the Notes to be immediately due and payable in the manner provided in Section 5.2 of the Indenture. All principal
payments on the Class A-4 Notes shall be made pro rata to the Holders entitled thereto if the Notes have been declared immediately due and payable. 

Payments of interest on this Class A-4 Note due and payable on any Distribution Date, together
with the installment of principal, if any, due and payable on such Distribution Date, to the extent not in full payment of this Class A-4 Note, shall be made by check mailed to the Person whose name
appears as the Holder of this Class A-4 Note (or one or more Predecessor Notes) on the Note Register as of the close of business on the Record Date preceding such Distribution Date or by wire transfer in
immediately available funds to the account designated in writing to the Indenture Trustee by such Person at least five (5) Business Days prior to the related Record Date, except that with respect to
Class A-4 Notes registered on the Record Date in the name of the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.), payments will be made by wire transfer in immediately
available funds to the account designated by such nominee. Such checks shall be mailed to the Person entitled thereto at the address of such Person as it appears on the Note Register as of such Record Date without requiring that this Class A-4 Note be submitted for notation of payment. Any reduction in the principal amount of this Class A-4 Note (or any one or more Predecessor Notes) effected by
any payments made on any Distribution Date shall be binding upon all future Holders of this Class A-4 Note and of any Class A-4 Note issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. If funds are expected to be available, as provided in the Indenture, for payment in 

  
 Ex. A-4-6 













 
full of the then remaining unpaid principal amount of this Class A-4 Note on a Distribution Date, then the Indenture Trustee, in the name of and on
behalf of the Issuer, shall notify the Person who was the Holder hereof as of the Record Date preceding such Distribution Date by notice mailed or transmitted by facsimile prior to such Distribution Date, and the amount then due and payable shall be
payable only upon presentation and surrender of this Class A-4 Note at the Indenture Trustee’s Corporate Trust Office or at the office of the Indenture Trustee’s agent appointed for such
purposes located in St. Paul, Minnesota. 
 The Issuer shall pay interest on overdue installments of interest at the Class A-4 Rate to the extent lawful. 
 As provided in the Indenture, the Notes may be redeemed, in
whole but not in part, in the manner and to the extent described in the Indenture and the Sale and Servicing Agreement. 
 As provided in
the Indenture, and subject to certain limitations set forth therein, the transfer of this Class A-4 Note may be registered on the Note Register upon surrender of this
Class A-4 Note for registration of transfer at the office or agency designated by the Issuer pursuant to the Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Indenture Trustee duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor institution” meeting the requirements of the Note
Registrar, and thereupon one or more new Class A-4 Notes in any authorized denomination and in the same aggregate principal amount will be issued to the designated transferee or transferees. No service
charge will be charged for any registration of transfer or exchange of this Class A-4 Note, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any such registration of transfer or exchange. 
 Each Noteholder or Note Owner, by its acceptance of a
Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer or the Indenture Trustee on the Notes or under the
Indenture or any certificate or other writing delivered in connection therewith against (i) the Indenture Trustee or the Owner Trustee, each in its individual capacity, (ii) any holder of a beneficial interest in the Issuer or
(iii) any partner, owner, beneficiary, agent, officer, director or employee of the Indenture Trustee or the Owner Trustee, each in its individual capacity, or any holder of a beneficial interest in the Issuer, the Owner Trustee or the Indenture
Trustee or any successor or assign of the Indenture Trustee or the Owner Trustee, each in its individual capacity, except as any such Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to
the extent provided by applicable law, for any unpaid consideration for stock, unpaid capital contribution for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. 

Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and
agrees that such Noteholder or Note Owner shall not at any time institute against the Depositor or the Issuer, or join in any institution against the Depositor or the Issuer of, any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under any United States federal or State bankruptcy or similar law in connection with any obligations relating to the Notes, the Certificates, the Indenture or any of the other Transaction Documents. 

  
 Ex. A-4-7 













 Each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note
Owner, a beneficial interest in this Note, agrees to provide to the Indenture Trustee, any Paying Agent or the Issuer, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the
Noteholder FATCA Information. In addition, each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note Owner, a beneficial interest in this Note, agrees that the Indenture Trustee has the right to withhold any amounts of
interest (properly withholdable under law and without any corresponding gross-up) payable to a Noteholder or holder of an interest in a Note that fails to comply with the requirements of the preceding
sentence. 
 The Issuer has entered into the Indenture and this Class A-4 Note is issued with
the intention that, for federal, State and local income, and franchise tax purposes, the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) will qualify as
indebtedness of the Issuer secured by the Trust Estate. Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, agrees to treat the Notes (other than any Retained Notes held by the
Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) for federal, State and local income, single business and franchise tax purposes as indebtedness of the Issuer. 

Prior to the due presentment for registration of transfer of this Class A-4 Note, the Issuer, the
Indenture Trustee and any agent of the Issuer or the Indenture Trustee may treat the Person in whose name this Class A-4 Note (as of the day of determination or as of such other date as may be specified
in the Indenture) is registered as the owner hereof for all purposes, whether or not this Class A-4 Note shall be overdue, and none of the Issuer, the Indenture Trustee or any such agent shall be affected
by notice to the contrary. 
 The Indenture permits the Owner Trustee, on behalf of the Issuer, and the Indenture Trustee, with certain
exceptions therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture without the consent of the Holders of the Notes. The Indenture also permits the Owner Trustee, on behalf of the Issuer, and the
Indenture Trustee, with certain exceptions as therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture with the consent of the Holders of Notes evidencing not less than 51% of the Note Balance of
the Controlling Class. The Indenture also permits the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class, on behalf of the Holders of all the Notes, to waive compliance by the Issuer with certain provisions of
the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holders of not less than 51% of the Note Balance of the Controlling Class or the Holder of this
Class A-4 Note (or any one or more Predecessor Notes) shall be conclusive and binding on such Holder and on all future Holders of this Class A-4 Note and of
any Class A-4 Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon this Class A-4 Note. 

  
 Ex. A-4-8 













 The term “Issuer”, as used in this Note, includes any successor to the Issuer
under the Indenture. 
 The Indenture permits the Issuer, under certain circumstances, to consolidate or merge with or into another Person,
subject to the rights of the Indenture Trustee and the Holders of Notes under the Indenture. 
 The Notes are issuable only in registered
form in denominations as provided in the Indenture, subject to certain limitations therein set forth. 
 THIS
CLASS A-4 NOTE AND THE INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAWS PROVISIONS THEREOF WHICH MAY REQUIRE THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION (OTHER THAN SECTION 5-1401
OF THE NEW YORK GENERAL OBLIGATIONS LAW). 
 No reference herein to the Indenture, and no provision of this Note or of the Indenture, shall
alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Class A-4 Note at the times, place and rate, and in the coin or currency,
herein prescribed. 
 Anything herein to the contrary notwithstanding, except as expressly provided in the Transaction Documents, none of
Wilmington Trust, National Association, in its individual capacity, U.S. Bank Trust National Association, in its individual capacity, any holder of a beneficial interest in the Issuer, or any of their respective owners, beneficiaries, agents,
officers, directors, employees or successors or assigns shall be personally liable for, nor shall recourse be had to any of them for, the payment of principal of or interest on this Class A-4 Note or the
performance of, or omission to perform, any of the covenants, obligations or indemnifications contained in the Indenture. The Holder of this Note, by its acceptance hereof, agrees that, except as expressly provided in the Transaction Documents, in
the case of an Event of Default under the Indenture, the Holder shall have no claim against any of the foregoing for any deficiency, loss or claim resulting therefrom; provided, however, that nothing contained herein shall be taken to prevent
recourse to, or enforcement against, the assets of the Issuer for any and all liabilities, obligations and undertakings contained in the Indenture or in this Class A-4 Note.

CarMax Auto Owner Trust 2022-4, a statutory trust organized and existing under the laws of the State
of Delaware (herein referred to as the “Issuer”), for value received, hereby promises to pay to [                ], or its registered assigns, the
principal sum of [                ] DOLLARS OR SUCH LESSER AMOUNT AS IS SET FORTH IN SCHEDULE I or such lesser amount payable on each Distribution Date in an amount
equal to the aggregate amount, if any, payable from the Note Payment Account in respect of principal on the Class B Notes pursuant to Section 2.8 of the Indenture dated as of October 1, 2022 (as amended, supplemented or otherwise
modified and in effect from time to time, the “Indenture”) between the Issuer and Wilmington Trust, National Association, a national banking association, as Indenture Trustee (in such capacity, the “Indenture
Trustee”); provided, however, that principal of this Class B Note will not be due and payable until the Class A-1 Notes, the
Class A-2a Notes, the Class A-2b Notes, the Class A-3 Notes and the
Class A-4 Notes have been paid in full; and, provided further, that, if not paid prior to such date, the unpaid principal amount of this Class B Note shall be due and payable on the
earlier of the July 2028 Distribution Date (the “Class B Final Distribution Date”) and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture. Capitalized terms used but not defined herein are
defined in Article I of the Indenture, which also contains rules as to construction that shall be applicable hereto. 
 The Issuer shall pay
interest on this Class B Note at the rate per annum shown above on each Distribution Date, until the principal of this Class B Note is paid or made available for payment, on the principal amount of this Class B Note outstanding on the
preceding Distribution Date (after giving effect to all payments of principal made on such preceding Distribution Date), subject to certain limitations contained in Section 3.1 of the Indenture. Interest on this Class B Note shall accrue
for each Distribution Date from and including the 15th day of the preceding month (or, in the case of the initial Distribution Date or if no interest has been paid, from and including the Closing Date) to but excluding the 15th day of the month in

(ii) the principal amount of this Class B Note outstanding as of the Closing Date (in the case of the first Distribution Date) or on the preceding Distribution Date (after giving effect to all payments of principal made on such preceding
Distribution Date). The principal of and interest on this Class B Note shall be paid in the manner specified on the reverse hereof.

 The principal of and interest on this Class B Note are payable in such coin or currency of the
United States as at the time of payment is legal tender for payment of public and private debts. All payments made by the Issuer with respect to this Class B Note shall be applied first to interest due and payable on this Class B Note as
provided above and then to the unpaid principal of this Class B Note. 
 Reference is hereby made to the further provisions of this
Class B Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if fully set forth on the face of this Class B Note.

 [REVERSE OF CLASS B NOTE] 

This Class B Note is one of a duly authorized issue of Notes of the Issuer, designated as its 6.01% Class B Asset-backed Notes,
which, together with the 4.466% Class A-1 Asset-backed Notes, the 5.34% Class A-2a Asset-backed Notes, the Benchmark + 0.90%
Class A-2b Asset-backed Notes, the 5.34% Class A-3 Asset-backed Notes, the 5.70% Class A-4 Asset-backed Notes, the
6.49% Class C Asset-backed Notes and the 8.08% Class D Asset-backed Notes (collectively, the “Notes”), are issued under the Indenture, to which Indenture and all indentures supplemental thereto reference is hereby made for
a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes. The Notes are subject to all terms of the Indenture. 

The Class B Notes are and shall be equally and ratably secured by the collateral pledged as security therefor as provided in the
Indenture. The Class B Notes are subordinated to the Class A-1 Notes, the Class A-2a Notes, the Class A-2b
Notes, the Class A-3 Notes and the Class A-4 Notes to the extent set forth in the Indenture and the Sale and Servicing Agreement. The Class C Notes and
the Class D Notes are subordinated to the Class B Notes to the extent set forth in the Indenture and the Sale and Servicing Agreement. 

As described above, the entire unpaid principal amount of this Class B Note shall be due and payable on the earlier of the Class B
Final Distribution Date and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture. Notwithstanding the foregoing, the entire unpaid principal amount of the Notes, together with accrued and unpaid interest thereon through the
date of acceleration, shall be due and payable on the date on which an Event of Default shall have occurred and be continuing if the Indenture Trustee or the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling
Class have declared the Notes to be immediately due and payable in the manner provided in Section 5.2 of the Indenture. All principal payments on the Class B Notes shall be made pro rata to the Holders entitled thereto if the Notes
have been declared immediately due and payable. 
 Payments of interest on this Class B Note due and payable on any Distribution Date,
together with the installment of principal, if any, due and payable on such Distribution Date, to the extent not in full payment of this Class B Note, shall be made by check mailed to the Person whose name appears as the Holder of this
Class B Note (or one or more Predecessor Notes) on the Note Register as of the close of business on the Record Date preceding such Distribution Date or by wire transfer in immediately available funds to the account designated in writing to the
Indenture Trustee by such Person at least five (5) Business Days prior to the related Record Date, except that with respect to Class B Notes registered on the Record Date in the name of the nominee of the Clearing Agency (initially, such
nominee to be Cede & Co.), payments will be made by wire transfer in immediately available funds to the account designated by such nominee. Such checks shall be mailed to the Person entitled thereto at the address of such Person as it
appears on the Note Register as of such Record Date without requiring that this Class B Note be submitted for notation of payment. Any reduction in the principal amount of this Class B Note (or any one or more Predecessor Notes) effected
by any payments made on any Distribution Date shall be binding upon all future Holders of this Class B Note and of any Class B Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not
noted hereon. If funds are expected to be available, as provided in the Indenture, for payment in full of the then remaining 

  
 Ex. B-6 













 
unpaid principal amount of this Class B Note on a Distribution Date, then the Indenture Trustee, in the name of and on behalf of the Issuer, shall notify the Person who was the Holder hereof
as of the Record Date preceding such Distribution Date by notice mailed or transmitted by facsimile prior to such Distribution Date, and the amount then due and payable shall be payable only upon presentation and surrender of this Class B Note
at the Indenture Trustee’s Corporate Trust Office or at the office of the Indenture Trustee’s agent appointed for such purposes located in St. Paul, Minnesota. 

The Issuer shall pay interest on overdue installments of interest at the Class B Rate to the extent lawful. 

As provided in the Indenture, the Notes may be redeemed, in whole but not in part, in the manner and to the extent described in the Indenture
and the Sale and Servicing Agreement. 
 As provided in the Indenture, and subject to certain limitations set forth therein, the transfer of
this Class B Note may be registered on the Note Register upon surrender of this Class B Note for registration of transfer at the office or agency designated by the Issuer pursuant to the Indenture, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Indenture Trustee duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor
institution” meeting the requirements of the Note Registrar, and thereupon one or more new Class B Notes in any authorized denomination and in the same aggregate principal amount will be issued to the designated transferee or transferees.
No service charge will be charged for any registration of transfer or exchange of this Class B Note, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with
any such registration of transfer or exchange. 
 Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note
Owner, a beneficial interest in a Note, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer or the Indenture Trustee on the Notes or under the Indenture or any certificate or
other writing delivered in connection therewith against (i) the Indenture Trustee or the Owner Trustee, each in its individual capacity, (ii) any holder of a beneficial interest in the Issuer or (iii) any partner, owner, beneficiary,
agent, officer, director or employee of the Indenture Trustee or the Owner Trustee, each in its individual capacity, or any holder of a beneficial interest in the Issuer, the Owner Trustee or the Indenture Trustee or any successor or assign of the
Indenture Trustee or the Owner Trustee, each in its individual capacity, except as any such Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided by applicable law, for
any unpaid consideration for stock, unpaid capital contribution for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. 

Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and
agrees that such Noteholder or Note Owner shall not at any time institute against the Depositor or the Issuer, or join in any institution against the Depositor or the Issuer of, any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under any United States federal or State bankruptcy or similar law in connection with any obligations relating to the Notes, the Certificates, the Indenture or any of the other Transaction Documents. 

  
 Ex. B-7 













 Each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note
Owner, a beneficial interest in this Note, agrees to provide to the Indenture Trustee, any Paying Agent or the Issuer, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the
Noteholder FATCA Information. In addition, each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note Owner, a beneficial interest in this Note, agrees that the Indenture Trustee has the right to withhold any amounts of
interest (properly withholdable under law and without any corresponding gross-up) payable to a Noteholder or holder of an interest in a Note that fails to comply with the requirements of the preceding
sentence. 
 The Issuer has entered into the Indenture and this Class B Note is issued with the intention that, for federal, State and
local income, and franchise tax purposes, the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) will qualify as indebtedness of the Issuer secured by the
Trust Estate. Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, agrees to treat the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same
Person as the Issuer for federal income tax purposes) for federal, State and local income, single business and franchise tax purposes as indebtedness of the Issuer. 

Prior to the due presentment for registration of transfer of this Class B Note, the Issuer, the Indenture Trustee and any agent of the
Issuer or the Indenture Trustee may treat the Person in whose name this Class B Note (as of the day of determination or as of such other date as may be specified in the Indenture) is registered as the owner hereof for all purposes, whether or
not this Class B Note shall be overdue, and none of the Issuer, the Indenture Trustee or any such agent shall be affected by notice to the contrary. 

The Indenture permits the Owner Trustee, on behalf of the Issuer, and the Indenture Trustee, with certain exceptions therein provided, to
amend or waive from time to time certain terms and conditions set forth in the Indenture without the consent of the Holders of the Notes. The Indenture also permits the Owner Trustee, on behalf of the Issuer, and the Indenture Trustee, with certain
exceptions as therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture with the consent of the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class. The
Indenture also permits the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class, on behalf of the Holders of all the Notes, to waive compliance by the Issuer with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or waiver by the Holders of not less than 51% of the Note Balance of the Controlling Class or the Holder of this Class B Note (or any one or more Predecessor Notes)
shall be conclusive and binding on such Holder and on all future Holders of this Class B Note and of any Class B Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such
consent or waiver is made upon this Class B Note. 

  
 Ex. B-8 













 The term “Issuer”, as used in this Note, includes any successor to the Issuer
under the Indenture. 
 The Indenture permits the Issuer, under certain circumstances, to consolidate or merge with or into another Person,
subject to the rights of the Indenture Trustee and the Holders of Notes under the Indenture. 
 The Notes are issuable only in registered
form in denominations as provided in the Indenture, subject to certain limitations therein set forth. 
 THIS CLASS B NOTE AND THE
INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS WITHOUT GIVING EFFECT TO THE
CONFLICTS OF LAWS PROVISIONS THEREOF WHICH MAY REQUIRE THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION (OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW). 

No reference herein to the Indenture, and no provision of this Note or of the Indenture, shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on this Class B Note at the times, place and rate, and in the coin or currency, herein prescribed. 

Anything herein to the contrary notwithstanding, except as expressly provided in the Transaction Documents, none of Wilmington Trust, National
Association, in its individual capacity, U.S. Bank Trust National Association, in its individual capacity, any holder of a beneficial interest in the Issuer, or any of their respective owners, beneficiaries, agents, officers, directors, employees or
successors or assigns shall be personally liable for, nor shall recourse be had to any of them for, the payment of principal of or interest on this Class B Note or the performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in the Indenture. The Holder of this Note, by its acceptance hereof, agrees that, except as expressly provided in the Transaction Documents, in the case of an Event of Default under the Indenture, the Holder shall have no
claim against any of the foregoing for any deficiency, loss or claim resulting therefrom; provided, however, that nothing contained herein shall be taken to prevent recourse to, or enforcement against, the assets of the Issuer for any and all
liabilities, obligations and undertakings contained in the Indenture or in this Class B Note.

The Issuer shall pay interest on this Class C Note at the rate per annum shown above on each Distribution Date, until the principal of

 Reference is hereby made to the further provisions of this
Class C Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if fully set forth on the face of this Class C Note.

 [REVERSE OF CLASS C NOTE] 

This Class C Note is one of a duly authorized issue of Notes of the Issuer, designated as its 6.49% Class C Asset-backed Notes,
which, together with the 4.466% Class A-1 Asset-backed Notes, the 5.34% Class A-2a Asset-backed Notes, the Benchmark + 0.90%
Class A-2b Asset-backed Notes, the 5.34% Class A-3 Asset-backed Notes, the 5.70% Class A-4 Asset-backed Notes, the
6.01% Class B Asset-backed Notes and the 8.08% Class D Asset-backed Notes (collectively, the “Notes”), are issued under the Indenture, to which Indenture and all indentures supplemental thereto reference is hereby made for
a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes. The Notes are subject to all terms of the Indenture. 

The Class C Notes are and shall be equally and ratably secured by the collateral pledged as security therefor as provided in the
Indenture. The Class C Notes are subordinated to the Class A-1 Notes, the Class A-2a Notes, the Class A-2b
Notes, the Class A-3 Notes, the Class A-4 Notes and the Class B Notes to the extent set forth in the Indenture and the Sale and Servicing Agreement. The
Class D Notes are subordinated to the Class C Notes to the extent set forth in the Indenture and the Sale and Servicing Agreement. 

As described above, the entire unpaid principal amount of this Class C Note shall be due and payable on the earlier of the Class C
Final Distribution Date and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture. Notwithstanding the foregoing, the entire unpaid principal amount of the Notes, together with accrued and unpaid interest thereon through the
date of acceleration, shall be due and payable on the date on which an Event of Default shall have occurred and be continuing if the Indenture Trustee or the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling
Class have declared the Notes to be immediately due and payable in the manner provided in Section 5.2 of the Indenture. All principal payments on the Class C Notes shall be made pro rata to the Holders entitled thereto if the Notes
have been declared immediately due and payable. 
 Payments of interest on this Class C Note due and payable on any Distribution Date,
together with the installment of principal, if any, due and payable on such Distribution Date, to the extent not in full payment of this Class C Note, shall be made by check mailed to the Person whose name appears as the Holder of this
Class C Note (or one or more Predecessor Notes) on the Note Register as of the close of business on the Record Date preceding such Distribution Date or by wire transfer in immediately available funds to the account designated in writing to the
Indenture Trustee by such Person at least five (5) Business Days prior to the related Record Date, except that with respect to Class C Notes registered on the Record Date in the name of the nominee of the Clearing Agency (initially, such
nominee to be Cede & Co.), payments will be made by wire transfer in immediately available funds to the account designated by such nominee. Such checks shall be mailed to the Person entitled thereto at the address of such Person as it
appears on the Note Register as of such Record Date without requiring that this Class C Note be submitted for notation of payment. Any reduction in the principal amount of this Class C Note (or any one or more Predecessor Notes) effected
by any payments made on any Distribution Date shall be binding upon all future Holders of this Class C Note and of any Class C Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not
noted hereon. If funds are expected to be available, as provided in the Indenture, for payment in full of the then remaining 

  
 Ex. C-6 













 
unpaid principal amount of this Class C Note on a Distribution Date, then the Indenture Trustee, in the name of and on behalf of the Issuer, shall notify the Person who was the Holder hereof
as of the Record Date preceding such Distribution Date by notice mailed or transmitted by facsimile prior to such Distribution Date, and the amount then due and payable shall be payable only upon presentation and surrender of this Class C Note
at the Indenture Trustee’s Corporate Trust Office or at the office of the Indenture Trustee’s agent appointed for such purposes located in St. Paul, Minnesota. 

The Issuer shall pay interest on overdue installments of interest at the Class C Rate to the extent lawful. 

As provided in the Indenture, the Notes may be redeemed, in whole but not in part, in the manner and to the extent described in the Indenture
and the Sale and Servicing Agreement. 
 As provided in the Indenture, and subject to certain limitations set forth therein, the transfer of
this Class C Note may be registered on the Note Register upon surrender of this Class C Note for registration of transfer at the office or agency designated by the Issuer pursuant to the Indenture, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Indenture Trustee duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor
institution” meeting the requirements of the Note Registrar, and thereupon one or more new Class C Notes in any authorized denomination and in the same aggregate principal amount will be issued to the designated transferee or transferees.
No service charge will be charged for any registration of transfer or exchange of this Class C Note, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with
any such registration of transfer or exchange. 
 Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note
Owner, a beneficial interest in a Note, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer or the Indenture Trustee on the Notes or under the Indenture or any certificate or
other writing delivered in connection therewith against (i) the Indenture Trustee or the Owner Trustee, each in its individual capacity, (ii) any holder of a beneficial interest in the Issuer or (iii) any partner, owner, beneficiary,
agent, officer, director or employee of the Indenture Trustee or the Owner Trustee, each in its individual capacity, or any holder of a beneficial interest in the Issuer, the Owner Trustee or the Indenture Trustee or any successor or assign of the
Indenture Trustee or the Owner Trustee, each in its individual capacity, except as any such Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided by applicable law, for
any unpaid consideration for stock, unpaid capital contribution for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. 

Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and
agrees that such Noteholder or Note Owner shall not at any time institute against the Depositor or the Issuer, or join in any institution against the Depositor or the Issuer of, any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under any United States federal or State bankruptcy or similar law in connection with any obligations relating to the Notes, the Certificates, the Indenture or any of the other Transaction Documents. 

  
 Ex. C-7 













 Each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note
Owner, a beneficial interest in this Note, agrees to provide to the Indenture Trustee, any Paying Agent or the Issuer, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the
Noteholder FATCA Information. In addition, each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note Owner, a beneficial interest in this Note, agrees that the Indenture Trustee has the right to withhold any amounts of
interest (properly withholdable under law and without any corresponding gross-up) payable to a Noteholder or holder of an interest in a Note that fails to comply with the requirements of the preceding
sentence. 
 The Issuer has entered into the Indenture and this Class C Note is issued with the intention that, for federal, State and
local income, and franchise tax purposes, the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) will qualify as indebtedness of the Issuer secured by the
Trust Estate. Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, agrees to treat the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same
Person as the Issuer for federal income tax purposes) for federal, State and local income, single business and franchise tax purposes as indebtedness of the Issuer. 

Prior to the due presentment for registration of transfer of this Class C Note, the Issuer, the Indenture Trustee and any agent of the
Issuer or the Indenture Trustee may treat the Person in whose name this Class C Note (as of the day of determination or as of such other date as may be specified in the Indenture) is registered as the owner hereof for all purposes, whether or
not this Class C Note shall be overdue, and none of the Issuer, the Indenture Trustee or any such agent shall be affected by notice to the contrary. 

The Indenture permits the Owner Trustee, on behalf of the Issuer, and the Indenture Trustee, with certain exceptions therein provided, to
amend or waive from time to time certain terms and conditions set forth in the Indenture without the consent of the Holders of the Notes. The Indenture also permits the Owner Trustee, on behalf of the Issuer, and the Indenture Trustee, with certain
exceptions as therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture with the consent of the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class. The
Indenture also permits the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class, on behalf of the Holders of all the Notes, to waive compliance by the Issuer with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or waiver by the Holders of not less than 51% of the Note Balance of the Controlling Class or the Holder of this Class C Note (or any one or more Predecessor Notes)
shall be conclusive and binding on such Holder and on all future Holders of this Class C Note and of any Class C Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such
consent or waiver is made upon this Class C Note. 

  
 Ex. C-8 













 The term “Issuer”, as used in this Note, includes any successor to the Issuer
under the Indenture. 
 The Indenture permits the Issuer, under certain circumstances, to consolidate or merge with or into another Person,
subject to the rights of the Indenture Trustee and the Holders of Notes under the Indenture. 
 The Notes are issuable only in registered
form in denominations as provided in the Indenture, subject to certain limitations therein set forth. 
 THIS CLASS C NOTE AND THE INDENTURE
SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAWS
PROVISIONS THEREOF WHICH MAY REQUIRE THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION (OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW). 

No reference herein to the Indenture, and no provision of this Note or of the Indenture, shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on this Class C Note at the times, place and rate, and in the coin or currency, herein prescribed. 

Anything herein to the contrary notwithstanding, except as expressly provided in the Transaction Documents, none of Wilmington Trust, National
Association, in its individual capacity, U.S. Bank Trust National Association, in its individual capacity, any holder of a beneficial interest in the Issuer, or any of their respective owners, beneficiaries, agents, officers, directors, employees or
successors or assigns shall be personally liable for, nor shall recourse be had to any of them for, the payment of principal of or interest on this Class C Note or the performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in the Indenture. The Holder of this Note, by its acceptance hereof, agrees that, except as expressly provided in the Transaction Documents, in the case of an Event of Default under the Indenture, the Holder shall have no
claim against any of the foregoing for any deficiency, loss or claim resulting therefrom; provided, however, that nothing contained herein shall be taken to prevent recourse to, or enforcement against, the assets of the Issuer for any and all
liabilities, obligations and undertakings contained in the Indenture or in this Class C Note.

6.01% Class B Asset-backed Notes and the 6.49% Class C Asset-backed Notes (collectively, the “Notes”), are issued under the Indenture, to which Indenture and all indentures supplemental thereto reference is hereby made for
a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes. The Notes are subject to all terms of the Indenture. 

The Class D Notes are and shall be equally and ratably secured by the collateral pledged as security therefor as provided in the
Indenture. The Class D Notes are subordinated to the Class A-1 Notes, the Class A-2a Notes, the Class A-2b
Notes, the Class A-3 Notes, the Class A-4 Notes, the Class B Notes and the Class C Notes to the extent set forth in the Indenture and the Sale and
Servicing Agreement. 
 As described above, the entire unpaid principal amount of this Class D Note shall be due and payable on the
earlier of the Class D Final Distribution Date and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture. Notwithstanding the foregoing, the entire unpaid principal amount of the Notes, together with accrued and unpaid
interest thereon through the date of acceleration, shall be due and payable on the date on which an Event of Default shall have occurred and be continuing if the Indenture Trustee or the Holders of Notes evidencing not less than 51% of the Note
Balance of the Controlling Class have declared the Notes to be immediately due and payable in the manner provided in Section 5.2 of the Indenture. All principal payments on the Class D Notes shall be made pro rata to the Holders
entitled thereto if the Notes have been declared immediately due and payable. 
 Payments of interest on this Class D Note due and
payable on any Distribution Date, together with the installment of principal, if any, due and payable on such Distribution Date, to the extent not in full payment of this Class D Note, shall be made by check mailed to the Person whose name
appears as the Holder of this Class D Note (or one or more Predecessor Notes) on the Note Register as of the close of business on the Record Date preceding such Distribution Date or by wire transfer in immediately available funds to the account
designated in writing to the Indenture Trustee by such Person at least five (5) Business Days prior to the related Record Date, except that with respect to Class D Notes registered on the Record Date in the name of the nominee of the
Clearing Agency (initially, such nominee to be Cede & Co.), payments will be made by wire transfer in immediately available funds to the account designated by such nominee. Such checks shall be mailed to the Person entitled thereto at the
address of such Person as it appears on the Note Register as of such Record Date without requiring that this Class D Note be submitted for notation of payment. Any reduction in the principal amount of this Class D Note (or any one or more
Predecessor Notes) effected by any payments made on any Distribution Date shall be binding upon all future Holders of this Class D Note and of any Class D Note issued upon the registration of transfer hereof or in exchange hereof or in
lieu hereof, whether or not noted hereon. If funds are expected to be available, as provided in the Indenture, for payment in full of the then remaining unpaid principal amount of this Class D Note on a Distribution Date, then the Indenture
Trustee, 

  
 Ex. D-6 













 
in the name of and on behalf of the Issuer, shall notify the Person who was the Holder hereof as of the Record Date preceding such Distribution Date by notice mailed or transmitted by facsimile
prior to such Distribution Date, and the amount then due and payable shall be payable only upon presentation and surrender of this Class D Note at the Indenture Trustee’s Corporate Trust Office or at the office of the Indenture
Trustee’s agent appointed for such purposes located in St. Paul, Minnesota. 
 The Issuer shall pay interest on overdue installments of
interest at the Class D Rate to the extent lawful. 
 As provided in the Indenture, the Notes may be redeemed, in whole but not in
part, in the manner and to the extent described in the Indenture and the Sale and Servicing Agreement. 
 As provided in the Indenture, and
subject to certain limitations set forth therein, the transfer of this Class D Note may be registered on the Note Register upon surrender of this Class D Note for registration of transfer at the office or agency designated by the Issuer
pursuant to the Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Indenture Trustee duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, with such
signature guaranteed by an “eligible guarantor institution” meeting the requirements of the Note Registrar, and thereupon one or more new Class D Notes in any authorized denomination and in the same aggregate principal amount will be
issued to the designated transferee or transferees. No service charge will be charged for any registration of transfer or exchange of this Class D Note, but the transferor may be required to pay a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any such registration of transfer or exchange. 
 Each Noteholder or Note Owner,
by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer or the Indenture Trustee on the
Notes or under the Indenture or any certificate or other writing delivered in connection therewith against (i) the Indenture Trustee or the Owner Trustee, each in its individual capacity, (ii) any holder of a beneficial interest in the
Issuer or (iii) any partner, owner, beneficiary, agent, officer, director or employee of the Indenture Trustee or the Owner Trustee, each in its individual capacity, or any holder of a beneficial interest in the Issuer, the Owner Trustee or the
Indenture Trustee or any successor or assign of the Indenture Trustee or the Owner Trustee, each in its individual capacity, except as any such Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully
liable, to the extent provided by applicable law, for any unpaid consideration for stock, unpaid capital contribution for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. 

Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, covenants and
agrees that such Noteholder or Note Owner shall not at any time institute against the Depositor or the Issuer, or join in any institution against the Depositor or the Issuer of, any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under any United States federal or State bankruptcy or similar law in connection with any obligations relating to the Notes, the Certificates, the Indenture or any of the other Transaction Documents. 

  
 Ex. D-7 













 Each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note
Owner, a beneficial interest in this Note, agrees to provide to the Indenture Trustee, any Paying Agent or the Issuer, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the
Noteholder FATCA Information. In addition, each Noteholder or Note Owner, by its acceptance of this Note or, in the case of a Note Owner, a beneficial interest in this Note, agrees that the Indenture Trustee has the right to withhold any amounts of
interest (properly withholdable under law and without any corresponding gross-up) payable to a Noteholder or holder of an interest in a Note that fails to comply with the requirements of the preceding
sentence. 
 The Issuer has entered into the Indenture and this Class D Note is issued with the intention that, for federal, State and
local income, and franchise tax purposes, the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same Person as the Issuer for federal income tax purposes) will qualify as indebtedness of the Issuer secured by the
Trust Estate. Each Noteholder or Note Owner, by its acceptance of a Note or, in the case of a Note Owner, a beneficial interest in a Note, agrees to treat the Notes (other than any Retained Notes held by the Issuer or a Person treated as the same
Person as the Issuer for federal income tax purposes) for federal, State and local income, single business and franchise tax purposes as indebtedness of the Issuer. 

Prior to the due presentment for registration of transfer of this Class D Note, the Issuer, the Indenture Trustee and any agent of the
Issuer or the Indenture Trustee may treat the Person in whose name this Class D Note (as of the day of determination or as of such other date as may be specified in the Indenture) is registered as the owner hereof for all purposes, whether or
not this Class D Note shall be overdue, and none of the Issuer, the Indenture Trustee or any such agent shall be affected by notice to the contrary. 

The Indenture permits the Owner Trustee, on behalf of the Issuer, and the Indenture Trustee, with certain exceptions therein provided, to
amend or waive from time to time certain terms and conditions set forth in the Indenture without the consent of the Holders of the Notes. The Indenture also permits the Owner Trustee, on behalf of the Issuer, and the Indenture Trustee, with certain
exceptions as therein provided, to amend or waive from time to time certain terms and conditions set forth in the Indenture with the consent of the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class. The
Indenture also permits the Holders of Notes evidencing not less than 51% of the Note Balance of the Controlling Class, on behalf of the Holders of all the Notes, to waive compliance by the Issuer with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or waiver by the Holders of not less than 51% of the Note Balance of the Controlling Class or the Holder of this Class D Note (or any one or more Predecessor Notes)
shall be conclusive and binding on such Holder and on all future Holders of this Class D Note and of any Class D Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such
consent or waiver is made upon this Class D Note. 
 The term “Issuer”, as used in this Note, includes any successor to the
Issuer under the Indenture. 

  
 Ex. D-8 













 The Indenture permits the Issuer, under certain circumstances, to consolidate or merge with
or into another Person, subject to the rights of the Indenture Trustee and the Holders of Notes under the Indenture. 
 The Notes are
issuable only in registered form in denominations as provided in the Indenture, subject to certain limitations therein set forth. 
 THIS
CLASS D NOTE AND THE INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS WITHOUT
GIVING EFFECT TO THE CONFLICTS OF LAWS PROVISIONS THEREOF WHICH MAY REQUIRE THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION (OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW). 

No reference herein to the Indenture, and no provision of this Note or of the Indenture, shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on this Class D Note at the times, place and rate, and in the coin or currency, herein prescribed. 

Anything herein to the contrary notwithstanding, except as expressly provided in the Transaction Documents, none of Wilmington Trust, National
Association, in its individual capacity, U.S. Bank Trust National Association, in its individual capacity, any holder of a beneficial interest in the Issuer, or any of their respective owners, beneficiaries, agents, officers, directors, employees or
successors or assigns shall be personally liable for, nor shall recourse be had to any of them for, the payment of principal of or interest on this Class D Note or the performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in the Indenture. The Holder of this Note, by its acceptance hereof, agrees that, except as expressly provided in the Transaction Documents, in the case of an Event of Default under the Indenture, the Holder shall have no
claim against any of the foregoing for any deficiency, loss or claim resulting therefrom; provided, however, that nothing contained herein shall be taken to prevent recourse to, or enforcement against, the assets of the Issuer for any and all
liabilities, obligations and undertakings contained in the Indenture or in this Class D Note.

 Exhibit E 

Form of Opinion of Counsel 
  

	A.	 The provisions of the Purchase Agreement are effective under the New York UCC to create in favor of the
Depositor a security interest in CarMax’s rights in the Receivables and in any identifiable proceeds thereof. (We note that a “security interest” as defined in Section 1-201(b)(35) of the
New York UCC includes the interests of a buyer of accounts, chattel paper, payment intangibles and promissory notes and we refer you to our other opinion of even date herewith with respect to whether the security interest of the Depositor should be
characterized as an ownership interest or solely as a collateral interest held to secure a loan made to CarMax). 


  

	B.	 The provisions of the Sale and Servicing Agreement are effective under the New York UCC to create in favor of
the Issuer a security interest in the Depositor’s rights in the Receivables and in any identifiable proceeds thereof. We express no opinion as to whether the security interest of the Issuer would be characterized as an ownership interest or
solely as a collateral interest held to secure a loan made to the Depositor. 


  

	C.	 The provisions of the Indenture are effective under the New York UCC to create in favor of the Indenture
Trustee a security interest in the Issuer’s rights in the Receivables and any identifiable proceeds thereof. 


  

	D.	 Under the New York UCC (including the choice of laws provisions thereof), while a debtor is “located”
in a jurisdiction, the local law of that jurisdiction governs the perfection by the filing of a financing statement of a security interest in personal property that is accounts, chattel paper, payment intangibles or instruments. Under the New York
UCC (including the choice of laws provisions thereof): 


  

	 	1.	 CarMax is “located” in Delaware and the local law of that state governs perfection of a nonpossessory
security interest in CarMax’s rights in the Receivables by the filing of a financing statement. 


  

	 	2.	 The Depositor is “located” in Delaware and the local law of that state governs perfection of a
nonpossessory security interest in the Depositor’s rights in the Receivables by the filing of a financing statement. 


  

	 	3.	 The Issuer is “located” in Delaware and the local law of that state governs perfection of a
nonpossessory security interest in the Issuer’s rights in the Receivables by the filing of a financing statement. 


  

	E.	 When the CarMax Financing Statement is filed (within the meaning of
Section 9-516 of the Delaware UCC) in the Delaware Filing Office, under the provisions of the Delaware UCC, the Depositor’s security interest in CarMax’s rights in the Receivables and in
identifiable cash proceeds thereof will be perfected.

 Mail Code: MK-IL-SL7C 

Chicago, Illinois 60603 
 Attn: CAOT 2022-4 
 Ladies and Gentlemen: 

In connection with our proposed purchase of Class ___ Notes (the “Class ___ Notes”) of CarMax Auto Owner Trust
2022-4 (the “Issuing Entity”), we confirm that: 

1.                We understand that the Class ___ Notes have not been
registered under the Securities Act of 1933, as amended (the “1933 Act”), and may not be sold except as permitted in the following sentence. We understand and agree, on our own behalf and on behalf of any accounts for which we are acting
as hereinafter stated, (x) that such Class ___ Notes are being offered only in a transaction not involving any public offering within the meaning of the 1933 Act and (y) that such Class ___ Notes may be resold, pledged or transferred only
(i) to CarMax Auto Funding LLC (the “Depositor”), (ii) so long as such Class ___ Note is eligible for resale pursuant to Rule 144A under the 1933 Act (“Rule 144A”), to a person whom we reasonably believe after due inquiry is
a “qualified institutional buyer” as defined in Rule 144A, acting for its own account (and not for the account of others) or as a fiduciary or agent for others (which others also are “qualified institutional buyers”) to whom
notice is given that the resale, pledge or transfer is being made in reliance on Rule 144A or (iii) in a sale, pledge or other transfer made in a transaction otherwise exempt from the registration requirements of the 1933 Act, in which case the
Indenture Trustee shall require that both the prospective transferor and the prospective transferee certify to the Indenture Trustee and the Depositor in writing the facts surrounding such transfer, which certification shall be in form and substance
satisfactory to the Indenture Trustee and the Depositor. Except in the case of a transfer described in clauses (i) or (ii) above, the Indenture Trustee shall require that a written 

  
 Ex. G-1 













 
opinion of counsel (which will not be at the expense of the Depositor, any Affiliate of the Depositor or the Indenture Trustee), satisfactory to the Indenture Trustee and the Depositor, be
delivered to the Indenture Trustee and the Depositor to the effect that such transfer will not violate the 1933 Act, and will be effected in accordance with any applicable securities laws of each state of the United States. We will notify any
purchaser of the Class ___ Notes from us of the above resale restrictions, if then applicable. We further understand that in connection with any transfer of the Class ___ Notes by us that the Indenture Trustee and the Depositor may request, and if
so requested we will furnish, such certificates and other information as they may reasonably require to confirm that any such transfer complies with the foregoing restrictions. 

2. [CHECK ONE] 
 ☐ (a) We are an
Accredited Investor acting for our own account (and not for the account of others) or as a fiduciary or agent for others (which others also are Accredited Investors unless we are a bank acting in its fiduciary capacity). We have such knowledge and
experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Class ___ Notes, and we and any accounts for which we are acting are each able to bear the economic risk of our or their
investment for an indefinite period of time. We are acquiring the Class ___ Notes or investment and not with a view to, or for offer and sale in connection with, a public distribution. 

☐ (b) We are a “qualified institutional buyer” as defined under Rule 144A under the 1933 Act and are acquiring the Class ___
Notes for our own account (and not for the account of others) or as a fiduciary or agent for others (which others also are “qualified institutional buyers”). We are familiar with Rule 144A under the 1933 Act and are aware that the seller
of the Class ___ Notes and other parties intend to rely on the statements made herein and the exemption from the registration requirements of the 1933 Act provided by Rule 144A. 

3. Either (i) we are not acquiring the Class ___ Notes with the assets of any (A) “employee benefit plan” as defined in Section 3(3) of
the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) that is subject to Title I of ERISA, (B) “plan” described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended (the
“Code”) that is subject to Section 4975 of the Code, (C) entity or account whose underlying assets include “plan assets” within the meaning of 29 C.F.R. Section 2510.3-101,
as modified by Section 3(42) of ERISA by reason of a plan’s investment in the entity or account or (D) employee benefit plan or arrangement that is not subject to Title I of ERISA or Section 4975 of the Code (each, a
“Plan”) or (ii) our acquisition and holding of the Class ___ Notes will not give rise to a nonexempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a violation of any federal, state, local
or other law that is substantially similar to Title I of ERISA or Section 4975 of the Code (“Similar Law”). We hereby acknowledge that no transfer of any Class ___ Note shall be permitted to be made to any transferee unless either
(i) such transferee is not acquiring the Class ___ Note with the assets of any Plan or (ii) the acquisition and holding of such Class ___ Note will not constitute or result in a nonexempt prohibited transaction under Section 406 of
ERISA or Section 4975 of the Code or a violation of Similar Law. 

  
 Ex. G-2 













 4. Unless counsel satisfactory to the Indenture Trustee shall have rendered an opinion to the effect that
the Class ___ Notes to be transferred will be characterized as indebtedness for United States federal income tax purposes, we represent that we are a United States person (within the meaning of Section 7701(a)(30) of the Code); and we
acknowledge that unless the Indenture Trustee shall have received such an opinion, no transfer of any Class ___ Note shall be permitted to be made to any person who is not a United States person (within the meaning of Section 7701(a)(30) of the
Code) and any such purported transfer in violation of these restrictions shall be null and void. 
 5. We understand that the Issuing Entity, the Indenture
Trustee, the Depositor and others will rely upon the truth and accuracy of the foregoing acknowledgments, representations and agreements, and we agree that if any of the acknowledgments, representations and warranties deemed to have been made by us
by our purchase of the Class ___ Notes, for our own account or for one or more accounts as to each of which we exercise sole investment discretion, are no longer accurate, we shall promptly notify the Depositor. 

6. You are entitled to rely upon this letter and you are irrevocably authorized to produce this letter or a copy hereof to any interested party in any
administrative or legal proceeding or official inquiry with respect to the matters covered hereby.
