(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. 

  
 16 








 (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. 

(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 will be
deemed to have represented and warranted, by its acceptance of the Note (or an interest therein), that either (a) it is not acquiring the Note (or an interest therein) with the plan assets of any (i) “employee benefit plan” (as


  
 17 








 
defined in Section 3(3) of ERISA) subject to the fiduciary requirements of ERISA, (ii) “plan” described in Section 4975(e)(1) of the Code, including individual retirement
accounts and Keogh plans, that is subject to the provisions of Section 4975 of the Code, or (iii) 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 the Note (or an interest therein) will not constitute or result in a non-exempt “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code or a violation of any substantially similar applicable
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 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. 

  
 18 








 (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.

Final Distribution Date, the principal amount of the Class A-2a Notes, to the extent not previously paid, shall be due and payable on the Class A-2a Final Distribution Date, the principal amount of the Class A-2b Notes, to the extent

(g) All principal and interest payments on each Class of Notes shall be made pro rata to the Holders of such Class. The
Indenture Trustee shall, before the Distribution Date on which the Issuer expects to pay the final installment of principal of and interest on any Note, notify the Holder of such Note as of the related Record Date of such final installment. Such
notice shall be mailed or transmitted by facsimile and shall specify that such final installment shall be payable only upon presentation and surrender of such Note and shall specify the place where such Note may be presented and surrendered for
payment of such installment. Notices in connection with redemption of Notes shall be mailed to Noteholders as provided in Section 10.2.

transfer, exchange or redemption in whole pursuant to 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. 
 Section 2.10 Release of Collateral.
Subject to Section 11.1 and the terms of the Transaction Documents, the Indenture Trustee shall release property from the lien of this Indenture only upon receipt of an Issuer Request (which shall include delivery instructions and other
relevant information) accompanied by an Officer’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 the lien of this Indenture in accordance with the conditions and procedures set forth in such exemptive order. 

Section 2.11 Book-Entry Notes. The 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; 

  

	 	(ii)	the Note Registrar and the Indenture Trustee shall be entitled to deal with the Clearing Agency for all 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; 


  
 24 









	 	(iii)	to the extent that the provisions of this Section 2.11 conflict with any other provisions of this Indenture, the provisions of this Section 2.11 shall control; 


 

	 	(iv)	the rights of Note Owners shall be exercised only through the Clearing Agency and shall be limited to those established by law and agreements between such Note Owners and the Clearing Agency and/or the Clearing Agency
Participants pursuant to the Note Depository Agreement; unless and until Definitive Notes are issued pursuant to Section 2.13, the initial Clearing Agency shall make book-entry transfers among the Clearing Agency Participants and receive and
transmit payments of principal of and interest on the Notes to such Clearing Agency Participants; and 

  

	 	(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. 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 

  
 25 








 
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”. 
 (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 Calculation Agent. 

(a) The Issuer hereby agrees that, for so long as any of the Class A-2b Notes remain Outstanding, the Issuer will at all times cause
there to be an agent appointed to calculate LIBOR in respect of each Accrual Period (the “Calculation Agent”), which agent shall (i) be a financial institution, subject to supervision or examination by federal or state
authority, (ii) have a rating of at least “BBB+” by Standard & Poor’s and “Baa1” by Moody’s, (iii) have an office within the United States and (iv) be engaged generally in transactions in U.S.
Eurodollar deposits in the international Eurodollar market. 
 (b) The Issuer hereby appoints the Indenture Trustee as Calculation Agent for
purposes of determining LIBOR on each LIBOR Determination Date for each Accrual Period. 

  
 26 








 (c) The Calculation Agent may be removed by the Issuer at any time. If the Calculation Agent is
unable or unwilling to act as such, is removed by the Issuer or fails to determine LIBOR for any Accrual Period, the Issuer will promptly appoint a replacement Calculation Agent. The Calculation Agent may not resign its duties without a successor
having been duly appointed.

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

(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

 (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

	 	(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

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 

  
 28 








 
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. 

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

Section 3.5 and designates 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. The Issuer further hereby authorizes 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 provision of Section 6.1 hereof. 

  
 29 








 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 2016), 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 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 Officer’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


  
 30 








 
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 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. 

  
 31 








 
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. 

Section 3.8 Negative Covenants. 

(a) If any Notes are Outstanding, the Issuer shall not: 
  

	 	(i)	except as expressly permitted by this Indenture, the Trust Agreement, the Receivables Purchase Agreement or the Sale and Servicing Agreement, sell, transfer, exchange or otherwise dispose of any of the properties or
assets of the Issuer, including those included in the Trust Estate, unless directed to do so in writing by the Indenture Trustee; 

  

	 	(ii)	claim any credit on, or make any deduction from the principal or interest payable in respect of, the Notes (other than amounts properly withheld from such payments under the Code or applicable State law) or assert any
claim against any present or former Noteholder by reason of the payment of taxes levied or assessed upon the Issuer; 

  

	 	(iii)	dissolve or liquidate in whole or in part; 

  

	 	(iv)	(A) permit the validity or effectiveness of this Indenture to be impaired, or permit the lien of this Indenture to be amended, hypothecated, subordinated, terminated or discharged, or permit any Person to be released
from any covenants or obligations with respect to the Notes under this Indenture except as may be expressly permitted hereby, (B) permit any lien (including any lien arising in connection with any tax imposed under HB3), 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




  
 32 









	 	
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. 

 Section 3.9 Annual Statement as to Compliance. 

(a) On or before May 31 of each year (commencing with the year 2016), the Issuer shall deliver to the Depositor and the Indenture Trustee

such condition or covenant, specifying each such default known to such Authorized Officer and the nature and status thereof.

indenture supplemental hereto, executed and delivered to the Indenture Trustee, in form satisfactory to the Depositor and the Indenture Trustee, the due and punctual payment of the principal of and interest on all Notes and the performance or

 (d) If there shall be pending, relative to the Issuer or any other obligor upon the Notes or any Person having or claiming an ownership
interest in the Trust Estate, Proceedings under Title 11 of the United States Code or any other applicable federal or State bankruptcy, insolvency or other similar law, or if a receiver, assignee or trustee in bankruptcy or reorganization,

Issuer or any other obligor upon the Notes, or to the creditors or property of the Issuer or such other obligor, the Indenture Trustee, irrespective of whether the principal of any Notes shall then be due and payable as therein expressed or by

Trustee, and their respective agents and attorneys, and all other amounts due and owing to the Indenture Trustee pursuant to Section 6.7.

 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;

	 	(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) in the following order of priority: 
  

	 	(i)	first, to the Servicer, the Total Servicing Fee for the preceding Collection Period and any Unreimbursed Servicer Advances for the preceding Collection Period;

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

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

	 	(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. 

  
 46 








 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 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 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, 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.



  
 47 








 (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 in its sole discretion may determine what action, if
any, shall be taken, notwithstanding any other provisions of this Indenture. 
 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. 
 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; 


  
 48 









	 	(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 

  

	 	(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,


  
 49 








 
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. 
 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).

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

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

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 to the requirements of this Indenture.

 (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. 

  
 52 








 (h) The Indenture Trustee shall not be charged with knowledge of any Event of Default or of any
other event unless either (i) a Responsible Officer shall have actual knowledge of such Event of Default or other event or (ii) written notice of such Event of Default or other event shall have been given to the Indenture Trustee in
accordance with the provisions of this Indenture.

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. 

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
Officer’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 Officer’s Certificate or Opinion of Counsel unless it is proved that the
Indenture Trustee was negligent in such reliance. 
 (c) The Indenture Trustee 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,

 (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. 

  
 53 








 (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. 
 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, 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 a 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 Default within ninety (90) days after it occurs. Except in the case of a Default in payment of principal of or interest on any Note (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 deliver, 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. 

  
 54 








 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 or expense (including
reasonable attorneys’ fees and expenses) incurred by it in connection with the administration of this trust and the performance of its duties hereunder; provided, however, that the Administrator need not indemnify the Indenture
Trustee for, or hold it harmless against, any such loss, liability 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; 


  
 55 









	 	(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. 

(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 

  
 56 








 
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. 


(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 

  
 57 








 
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 Trustee or its parent shall
have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition and shall have a long-term debt rating acceptable to each of the Rating Agencies. The Indenture Trustee shall comply
with TIA Section 310(b). 
 (b) Within 90 days after ascertaining the occurrence of an Event of Default which shall not have been cured
or waived, unless authorized by the Commission, the Indenture Trustee shall resign with respect to the Class A Notes, the Class B Notes, the Class C Notes or the Class D Notes in accordance with Section 6.8, and the Issuer shall appoint a
successor Indenture Trustee for one or more of such Classes, as applicable, so that there will be separate Indenture Trustees for the Class A Notes, the Class B Notes, the Class C Notes or the Class D Notes. In the event the Indenture Trustee
fails to comply with the terms of the preceding sentence, the Indenture Trustee shall comply with clauses (ii) and (iii) of TIA Section 310(b). 

(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


  
 58 








 
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. 

Section 6.12 Preferential Collection of Claims Against Issuer. The Indenture Trustee shall comply with TIA Section 311(a),
excluding any creditor relationship listed in TIA Section 311(b). An Indenture Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated. 

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

 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. 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. 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. 

(b) Subject to Section 6.1(c), the Indenture Trustee shall not in any way be held 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 Indenture Trustee by 11:00 A.M. (New York City time) (or such other time as may be agreed upon by the Issuer and Indenture Trustee), on the Business
Day preceding each Distribution Date, (ii) a Default or Event of Default shall have occurred and be continuing with respect to the Notes but the Notes shall not have been declared immediately due and payable pursuant to Section 5.2 or
(iii) the Notes shall have been declared immediately due and payable following an Event of Default, amounts collected or receivable from the Trust Estate are being applied in accordance with Section 5.4 as if there had not been such a
declaration, then the Indenture Trustee shall, to the fullest extent practicable, invest and reinvest funds in the Trust Accounts in one or more Permitted Investments. 

Section 8.4 Release of Trust Estate. 

(a) Subject to the payment of its fees and expenses pursuant to Section 6.7, the Indenture Trustee may, and when required by the
provisions of this Indenture shall, execute instruments to release property from the lien of this Indenture, or convey the Indenture Trustee’s interest in the same, in a manner and under circumstances that are not inconsistent with the
provisions of this Indenture. No party relying upon an instrument executed by the Indenture Trustee as provided in this Article VIII shall be bound to ascertain the Indenture Trustee’s authority, inquire into the satisfaction of any conditions
precedent or see to the application of any monies. 
 (b) The Indenture Trustee shall, at such time as there are no Notes Outstanding and
all sums due the Indenture Trustee pursuant to Section 6.7 have been paid in full, release any remaining portion of the Trust Estate that secured the Notes from the lien of this Indenture and release to the Issuer or any other Person entitled
thereto any funds then on deposit in the Trust Accounts. The Indenture Trustee shall release property from the lien of this Indenture pursuant to this Section (b) only upon receipt of an Issuer Request accompanied by an Officer’s
Certificate, an Opinion of Counsel addressed to the Indenture Trustee and (if required by the TIA) Independent Certificates in accordance with TIA Sections 314(c) and 314(d)(1) meeting the applicable requirements of Section 11.1.

 Section 8.5 Opinion of Counsel. The Indenture Trustee shall receive at least seven
(7) days notice when requested by the Issuer to take any action pursuant to Section 8.4(a), accompanied by copies of any instruments involved, and the Indenture Trustee shall also require, except in connection with any action 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. 
 ARTICLE IX 

SUPPLEMENTAL INDENTURES 

Section 9.1 Supplemental Indentures Without Consent of Noteholders. 

(a) The Issuer and the Indenture Trustee, when authorized by an Issuer Order, may, without the consent of the Holders of any Notes, with prior
written notice to the Rating Agencies and the Administrator, at any time and from time to time, enter into one or more indentures supplemental hereto, in form satisfactory to the Indenture Trustee, for any of the following purposes: 

 

	 	(i)	to correct or amplify the description of any property at any time subject to the lien of this Indenture, or better to assure, convey and confirm unto the Indenture Trustee any property subject or required to be
subjected to the lien of this Indenture, or to subject to the lien of this Indenture additional property; 

  

	 	(ii)	to evidence the succession, in compliance with the applicable provisions hereof, of another Person to the Issuer, and the assumption by any such successor of the covenants of the Issuer herein and in the Notes
contained; 


  
 63 









	 	(iii)	to add to the covenants of the Issuer, for the benefit of the Holders of the Notes, or to surrender any right or power herein conferred upon the Issuer; 


 

	 	(iv)	to convey, transfer, assign, mortgage or pledge any property to or with the Indenture Trustee; 

  

	 	(v)	to cure any ambiguity, to correct or supplement any provision herein or in any supplemental indenture that may be inconsistent with any other provision herein or in any supplemental indenture or in any offering document
used in connection with the initial offer and sale of the Notes or to add any provisions to or change in any manner or eliminate any of the provisions of this Indenture which will not be inconsistent with other provisions of this Indenture;


  

	 	(vi)	to evidence and provide for the acceptance of the appointment hereunder by a successor trustee with respect to the Notes and to add to or change any of the provisions of this Indenture as shall be necessary to
facilitate the administration of the trusts hereunder by more than one trustee, pursuant to the requirements of Article VI; or 

  

	 	(vii)	to modify, eliminate or add to the provisions of this Indenture to such extent as shall be necessary to effect the qualification of this Indenture under the TIA or under any similar federal statute hereafter enacted and
to add to this Indenture such other provisions as may be expressly required by the TIA; 

 provided, however, that (i) no
such supplemental indenture may materially adversely affect the interests of any Noteholder, and (ii) no such supplemental indenture will be permitted unless an Opinion of Counsel is delivered to the Indenture Trustee to the effect that such
supplemental indenture will not cause the Issuer to be characterized for federal income tax purposes as an association taxable as a corporation or otherwise have any material adverse impact on the federal income taxation of any Notes Outstanding or
any Noteholder. A supplemental indenture shall be deemed not to materially adversely affect the interests of any Noteholder if (i) the Person requesting such supplemental indenture obtains and delivers to the Indenture Trustee an Opinion of
Counsel to that effect or (ii) the Rating Agency Condition is satisfied. The Indenture Trustee is hereby authorized to join in the execution of any such supplemental indenture and to make any further appropriate agreements and stipulations that
may be therein contained.

one or more indentures supplemental hereto for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, this Indenture or modifying in any manner the rights of the Holders of the Notes under this
Indenture; provided, however, that (i) no such supplemental indenture may materially adversely affect the interests of any Noteholder and (ii) no such supplemental indenture will be permitted unless an Opinion of Counsel is
delivered to the Indenture Trustee to the effect that such supplemental indenture will not cause the Issuer to be characterized for federal income tax purposes as an association taxable as a corporation or otherwise have any material adverse impact
on the federal income taxation of any Notes Outstanding or any Noteholder; and, provided further, that no such supplemental indenture may, without the consent of the Holder of each Outstanding Note affected by such supplemental indenture: 

 

	 	(i)	change any Class Final Distribution Date or the date of payment of any installment of principal of or interest on any Note, or reduce the principal amount thereof, the Note Rate applicable thereto or the Redemption
Price with respect thereto, change the provisions of this Indenture relating to the application of collections on, or the proceeds of the sale of, the Trust Estate to payment of principal of or interest on the Notes, or change any place of payment
where, or the coin or currency in which, any Note or the interest thereon is payable; 

  

	 	(ii)	impair the right to institute suit for the enforcement of the provisions of this Indenture requiring the application of available funds, as provided in Article V, to the payment of any amount due on the Notes on or

	 	(v)	 reduce the percentage of the Note Balance the consent of the Holders of which is required to direct the Indenture Trustee to sell




  
 65 









	 	
or liquidate the Trust Estate pursuant to Section 5.4 if the proceeds of such sale would be insufficient to pay in full the principal amount of and accrued but unpaid interest on the Notes;


  

	 	(vi)	reduce the percentage of the Note Balance of the Controlling Class the consent of the Holders of which is required for any such supplemental indenture amending the provisions of this Indenture which specify the
applicable percentage of the Note Balance of the Controlling Class the consent of which is required for such supplemental indenture or the amendment of any other Transaction Document; 


 

	 	(vii)	affect the calculation of the amount of interest on or principal of the Notes payable on any Distribution Date, including the calculation of any of the individual components of such calculation; 


 

	 	(viii)	modify any of the provisions of this Indenture in such a manner as to affect the rights of the Holders of the Notes to the benefit of any provisions for the mandatory redemption of the Notes; or

of this Indenture on any such collateral at any time subject hereto or deprive the Holder of any Note of the security provided by the lien of this Indenture. 


(b) It shall not be necessary for any Act of Noteholders under this Section 9.2 to approve the 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 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 

  
 66 








 
indenture shall be effective without the prior written consent of the Owner Trustee if the supplemental indenture would adversely modify the amount or timing of distributions to be made to the
Owner Trustee under this Indenture. 
 Section 9.4 Effect of Supplemental Indenture. Upon the execution of any supplemental
indenture pursuant to the provisions hereof, this Indenture shall be and shall be deemed to be modified and amended in accordance therewith with respect to the Notes affected thereby, and the respective rights, limitations of rights, obligations,
duties, liabilities and immunities under this Indenture of the Indenture Trustee, the Issuer and the Holders of the Notes shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such 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.

 70 








 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. 

(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

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.

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. 

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.

 Section 11.7 Conflict with Trust Indenture Act. If any provision hereof limits,
qualifies or conflicts with another provision hereof that is required to be included in this Indenture by any of the provisions of the Trust Indenture Act, such required provision shall control. The provisions of TIA Sections 310 through 317 that
impose duties on any Person (including the provisions automatically deemed included herein unless expressly excluded by this Indenture) are a part of and govern this Indenture, whether or not physically contained herein. 

Section 11.8 Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for
convenience of reference only and shall not define or limit any of the terms or provisions hereof. 
 Section 11.9 Successors and
Assigns. All covenants and agreements in this Indenture and the Notes by the Issuer shall bind its successors and assigns, whether so expressed or not. All agreements of the Indenture Trustee in this Indenture shall bind its successors,
co-trustees and agents. 
 Section 11.10 Severability. If any provision of this Indenture or the Notes shall be invalid, illegal
or unenforceable, the validity, legality, and enforceability of the remaining provisions of this Indenture and the Notes shall not in any way be affected or impaired thereby. 

Section 11.11 Benefits of Indenture. Nothing in this Indenture or in the Notes, express or implied, shall give to any Person,
other than the parties hereto and their successors hereunder, the Noteholders, any other party secured hereunder and any other Person with an ownership interest in any part of the Trust Estate, any benefit or any legal or equitable right, remedy or
claim under this Indenture. 
 Section 11.12 Legal Holiday. If the date on which any payment is due shall not be a Business Day,
then (notwithstanding any other provision of the Notes or this Indenture) payment need not be made on such date but may be made on the next succeeding Business Day with the same force and effect as if made on the date on which nominally due, and no
interest shall accrue for the period from and after any such nominal date. 
 Section 11.13 GOVERNING LAW; WAIVER OF RIGHT TO JURY
TRIAL. 
 (a) THIS INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES UNDER THIS INDENTURE 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). 
 (B) TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY HERETO IRREVOCABLY
WAIVES ALL RIGHT OF TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BASED ON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS INDENTURE OR ANY MATTER ARISING HEREUNDER. 

  
 74 








 Section 11.14 Counterparts. This Indenture may be executed in any number of
counterparts, each of which counterparts when so executed shall be deemed to be an original, and all of which counterparts shall together constitute but one and the same instrument. 

Section 11.15 Recording of Indenture. If this Indenture is subject to recording in any appropriate public recording office, such
recording shall be effected by the Issuer at its expense and shall be accompanied by an Opinion of Counsel (which may be counsel to the Indenture Trustee or any other counsel reasonably acceptable to the Indenture Trustee) to the effect that such
recording is necessary either for the protection of the Noteholders or any other Person secured hereunder or for the enforcement of any right or remedy granted to the Indenture Trustee under this Indenture. 

Section 11.16 Trust Obligation. No recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer,
the Owner Trustee or the Indenture Trustee on the Notes or under this Indenture or any certificate or other writing delivered in connection herewith or therewith against (i) the Indenture Trustee or the Owner Trustee in its individual capacity,
(ii) any holder of a beneficial interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer, director, employee or agent of the Indenture Trustee or the Owner Trustee in its individual capacity, of any holder of a
beneficial interest in the Issuer, the Owner Trustee or the Indenture Trustee or of any successor or assign of the Indenture Trustee or the Owner Trustee in its individual capacity, except as any such Person may have expressly agreed (it being
understood that the Indenture Trustee and the Owner Trustee have no such obligations in their individual capacities), 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 or failure to pay any installment or call owing to such entity. For all purposes of this Indenture, in the performance of any duties or obligations of the Issuer hereunder, the Owner
Trustee shall be subject to, and entitled to the benefits of, the terms and provisions of Article VI, Article VII and Article VIII of the Trust Agreement. 

Section 11.17 No Petition. The Indenture Trustee, by entering into this Indenture, and each Noteholder or Note Owner, by accepting
a Note or beneficial interest in a Note, as the case may be, hereby covenant and agree that they will not at any time institute against the Depositor or the Issuer, or join in any institution against the Depositor or the Issuer of, or cooperate with
or encourage others to institute against the Depositor or the Issuer, any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings or other proceedings under any United States federal or State bankruptcy or similar law in
connection with any obligations relating to the Notes, this Indenture or any of the other Transaction Documents. 
 Section 11.18
Inspection. The Issuer shall, with reasonable prior notice, permit any representative of the Indenture Trustee, during the Issuer’s normal business hours, to examine the books of account, records, reports and other papers of the Issuer,
to make copies and extracts therefrom, to cause such books to be audited by Independent certified public accountants, and to discuss the Issuer’s affairs, finances and accounts with the Issuer’s officers, employees, and Independent
certified public accountants, all at such reasonable times and as often as may be 

  
 75 








 
reasonably requested. The Indenture Trustee shall and shall cause its representatives to hold in confidence all such information except to the extent disclosure may be required by law (and all
reasonable applications for confidential treatment are unavailing) and except to the extent that the Indenture Trustee may reasonably determine that such disclosure is consistent with its obligations hereunder. 

Section 11.19 Third-Party Beneficiaries. This Indenture shall inure to the benefit of and be binding upon the parties hereto, the
Owner Trustee, the Noteholders, the Certificateholders and their respective successors and permitted assigns. Except as otherwise provided in this Article XI, no other Person shall have any right or obligation hereunder. 

Section 11.20 Limitation on Recourse to CarMax Funding. Notwithstanding anything to the contrary contained herein, the Depositor
shall only be required to pay (i) any fees, expenses, indemnities or other liabilities that it may incur under the Transaction Documents from funds available pursuant to, and in accordance with, the applicable payment priorities set forth in
the Transaction Documents and (ii) to the extent the Depositor has additional funds available (other than funds described in the preceding clause (i)) that would be in excess of amounts that would be necessary to pay the debt and other
obligations of the Depositor in accordance with the Depositor’s certificate of formation, operating agreement and all financing documents to which the Depositor is a party. The agreement set forth in the preceding sentence shall constitute a
subordination agreement for purposes of Section 510(a) of the Bankruptcy Code. In addition, no amount owing by the Depositor under any Transaction Document in excess of liabilities that it is required to pay in accordance with the preceding
sentence shall constitute a “claim” (as defined in Section 101(5) of the Bankruptcy Code) against it.

 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” (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 2015-4 

0.42000% CLASS A-1 ASSET-BACKED NOTE 

CarMax Auto Owner Trust 2015-4, 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 Cede & Co., or its registered assigns, the principal sum of [        ] DOLLARS 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, 2015 (as amended, supplemented or otherwise
modified and in effect from time to time, the “Indenture”) between the Issuer and Wells Fargo Bank, 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 of the October 17, 2016 Distribution Date (the
“Class A-1 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-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


  
 Ex. A-1-1 








 
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 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-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) and (iii) the actual number of days in the applicable interest period divided by
360; provided, however, that the interest payable on this Class A-1 Note on November 16, 2015 shall equal $39,678.33. The principal of and interest on this Class A-1 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 16, 2015. 
 The principal of and interest on this Class A-1 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-1 Note shall be applied first to interest due and payable
on this Class A-1 Note as provided above and then to the unpaid principal of this Class A-1 Note. 
 Reference is hereby made to
the further provisions of this Class A-1 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-1 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-1 Note shall not entitle the Holder hereof to any benefit under the Indenture or be valid for any purpose.

 [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 0.42000% Class A-1 Asset-backed
Notes, which, together with the 1.09% Class A-2a Asset-backed Notes, the LIBOR + 0.60% Class A-2b Asset-backed Notes, the 1.56% Class A-3 Asset-backed Notes, the 1.83% Class A-4 Asset-backed Notes, the 2.16% Class B Asset-backed
Notes, the 2.50% Class C Asset-backed Notes and the 3.00% 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


  
 Ex. A-1-4 








 
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-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 the Borough of Manhattan, The City of New York. 

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-1-5 








 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, represents and warrants that either (a) it is not acquiring the Note (or an interest therein) with the plan assets of any (i) “employee benefit plan” (as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) subject to the fiduciary requirements of ERISA, (ii) “plan” described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended
(the “Code”), including individual retirement accounts and Keogh plans, that is subject to the provisions of Section 4975 of the Code, or (iii) 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 the Note will not constitute or result in a non-exempt “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code or a violation of
any substantially similar applicable law. 
 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 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 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 

  
 Ex. A-1-6 








 
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. 

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 Wells Fargo Bank, 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 partners, 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.

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, 2015 (as amended, supplemented or otherwise
modified and in effect from time to time, the “Indenture”) between the Issuer and Wells Fargo Bank, National Association, a national banking association, as Indenture Trustee (in such capacity, the “Indenture

 [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 1.09% Class A-2a Asset-backed
Notes, which, together with the 0.42000% Class A-1 Asset-backed Notes, the LIBOR + 0.60% Class A-2b Asset-backed Notes, the 1.56% Class A-3 Asset-backed Notes, the 1.83% Class A-4 Asset-backed Notes, the 2.16% Class B
Asset-backed Notes, the 2.50% Class C Asset-backed Notes and the 3.00% 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


  
 Ex. A-2a-4 








 
Class A-2a 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-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 the Borough of Manhattan, The City of New York. 

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 

  
 Ex. A-2a-5 








 
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. 
 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, represents and warrants that either (a) it is not acquiring the Note (or an interest therein) with the plan assets of any
(i) “employee benefit plan” (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) subject to the fiduciary requirements of ERISA, (ii) “plan”
described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended (the “Code”), including individual retirement accounts and Keogh plans, that is subject to the provisions of Section 4975 of the Code, or
(iii) 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 the Note will not constitute or result in a non-exempt “prohibited transaction”
under Section 406 of ERISA or Section 4975 of the Code or a violation of any substantially similar applicable law. 
 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 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 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-2a 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-2a 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-2a 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 

  
 Ex. A-2a-6 








 
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-2a 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-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 notation of such consent or waiver is made upon this Class A-2a Note. 

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-2A 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-2a 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 Wells Fargo Bank, 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 partners, 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-2a 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-2a Note.

 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, represents and warrants that either (a) it is not acquiring the Note (or an interest therein) with the plan assets of any
(i) “employee benefit plan” (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) subject to the fiduciary requirements of ERISA, (ii) “plan”

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 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

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 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. 

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

modified and in effect from time to time, the “Indenture”) between the Issuer and Wells Fargo Bank, 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

 [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 1.56% Class A-3 Asset-backed Notes,
which, together with the 0.42000% Class A-1 Asset-backed Notes, the 1.09% Class A-2a Asset-backed Notes, the LIBOR + 0.60% Class A-2b Asset-backed Notes, the 1.83% Class A-4 Asset-backed Notes, the 2.16% Class B Asset-backed

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

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

 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

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 

  
 Ex. A-3-4 








 
Indenture, for payment in 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 the Borough of Manhattan, The City of
New York. 
 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.

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-3-5 








 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, represents and warrants that either (a) it is not acquiring the Note (or an interest therein) with the plan assets of any (i) “employee benefit plan” (as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) subject to the fiduciary requirements of ERISA, (ii) “plan” described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended
(the “Code”), including individual retirement accounts and Keogh plans, that is subject to the provisions of Section 4975 of the Code, or (iii) 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 the Note will not constitute or result in a non-exempt “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code or a violation of
any substantially similar applicable law. 
 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 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 for federal, State and local income, single business and franchise tax purposes as indebtedness of the Issuer. 
 Prior to

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%

 Ex. A-3-6 








 
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. 

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.

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

 [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 1.83% Class A-4 Asset-backed Notes,
which, together with the 0.42000% Class A-1 Asset-backed Notes, the 1.09% Class A-2a Asset-backed Notes, the LIBOR + 0.60% Class A-2b Asset-backed Notes, the 1.56% Class A-3 Asset-backed Notes, the 2.16% Class B Asset-backed
Notes, the 2.50% Class C Asset-backed Notes and the 3.00% 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 

  
 Ex. A-4-4 








 
Indenture, for payment in 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 the Borough of Manhattan, The City of
New York. 
 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-4-5 








 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, represents and warrants that either (a) it is not acquiring the Note (or an interest therein) with the plan assets of any (i) “employee benefit plan” (as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) subject to the fiduciary requirements of ERISA, (ii) “plan” described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended
(the “Code”), including individual retirement accounts and Keogh plans, that is subject to the provisions of Section 4975 of the Code, or (iii) 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 the Note will not constitute or result in a non-exempt “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code or a violation of
any substantially similar applicable law. 
 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 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 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 

  
 Ex. A-4-6 








 
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. 

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 Wells Fargo Bank, 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 partners, 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.

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

 Ex. B-5 








 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, represents and warrants that either (a) it is not acquiring the Note (or an interest therein) with the plan assets of any (i) “employee benefit plan” (as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) subject to the fiduciary requirements of ERISA, (ii) “plan” described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended
(the “Code”), including individual retirement accounts and Keogh plans, that is subject to the provisions of Section 4975 of the Code, or (iii) 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 the Note will not constitute or result in a non-exempt “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code or a violation of
any substantially similar applicable law. 
 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 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 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 

  
 Ex. B-6 








 
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. 

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 Wells Fargo Bank, 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 partners, 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.

equal to the aggregate amount, if any, payable from the Note Payment Account in respect of principal on the Class C Notes pursuant to Section 2.8 of the Indenture dated as of October 1, 2015 (as amended, supplemented or otherwise modified
and in effect from time to time, the “Indenture”) between the Issuer and Wells Fargo Bank, National Association, a national banking association, as Indenture Trustee (in such capacity, the “Indenture Trustee”);
provided, however, that principal of this Class C 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,
the Class A-4 Notes and the Class B Notes have been paid in full; and, provided further, that, if not paid prior to such date, the unpaid principal amount of this Class C Note shall be due and payable on the earlier of the

 [REVERSE OF CLASS C NOTE] 

This Class C Note is one of a duly authorized issue of Notes of the Issuer, designated as its 2.50% Class C Asset-backed Notes, which,
together with the 0.42000% Class A-1 Asset-backed Notes, the 1.09% Class A-2a Asset-backed Notes, the LIBOR + 0.60% Class A-2b Asset-backed Notes, the 1.56% Class A-3 Asset-backed Notes, the 1.83% Class A-4 Asset-backed
Notes, the 2.16% Class B Asset-backed Notes and the 3.00% 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, 

  
 Ex. C-4 








 
for payment in full of the then remaining 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 the Borough of Manhattan, The City of New York. 

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.

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-5 








 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, represents and warrants that either (a) it is not acquiring the Note (or an interest therein) with the plan assets of any (i) “employee benefit plan” (as defined in Section 3(3) of the

(the “Code”), including individual retirement accounts and Keogh plans, that is subject to the provisions of Section 4975 of the Code, or (iii) 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 the Note will not constitute or result in a non-exempt “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code or a violation of
any substantially similar applicable law.

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.

franchise tax purposes, the Notes 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

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

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. 

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

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 D 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 D Note on each Distribution Date shall equal one-twelfth of the
product of (i) the rate per annum shown above and (ii) the principal amount of this Class D Note outstanding on the preceding Distribution Date (after giving effect to all payments of principal made on such preceding Distribution Date);
provided, however, that the interest payable on this Class D Note on November 16, 2015 shall equal $37,187.50. The principal of and interest on this Class D 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 16, 2015. 
 The principal of and interest on this Class D 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 D Note shall be applied first to interest due and payable on this Class D Note as provided
above and then to the unpaid principal of this Class D Note. 
 Reference is hereby made to the further provisions of this Class D 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 D 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 D Note shall not entitle the Holder hereof to any benefit under the Indenture or be valid for any purpose.

 [REVERSE OF CLASS D NOTE] 

This Class D Note is one of a duly authorized issue of Notes of the Issuer, designated as its 3.00% Class D Asset-backed Notes, which,
together with the 0.42000% Class A-1 Asset-backed Notes, the 1.09% Class A-2a Asset-backed Notes, the LIBOR + 0.60% Class A-2b Asset-backed Notes, the 1.56% Class A-3 Asset-backed Notes, the 1.83% Class A-4 Asset-backed
Notes, the 2.16% Class B Asset-backed Notes and the 2.50% 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 

  
 Ex. D-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 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 the Borough of Manhattan, The City of New York. 

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-5 








 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, represents and warrants that either (a) it is not acquiring the Note (or an interest therein) with the plan assets of any (i) “employee benefit plan” (as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) subject to the fiduciary requirements of ERISA, (ii) “plan” described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended
(the “Code”), including individual retirement accounts and Keogh plans, that is subject to the provisions of Section 4975 of the Code, or (iii) 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 the Note will not constitute or result in a non-exempt “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code or a violation of
any substantially similar applicable law. 
 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 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 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 

  
 Ex. D-6 








 
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. 

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 Wells Fargo Bank, 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 partners, 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 
  

	1.	Pursuant to Sections 18-201(a), 18-204 and 18-206 of the Delaware Limited Liability Company Act, the Secretary of State of the State of Delaware is required to maintain a public record showing limited liability
companies that have been organized. Pursuant to Section 3810, Section 3811 and Section 3812 of the Delaware Statutory Trust Act, the Secretary of State of the State of Delaware is required to maintain a public record showing statutory
trusts that have been formed. Based solely on our review of (i) the Delaware Limited Liability Company Act as found in “Corporation: Covering Corporation Practice, Procedure, Law - Aspen Law & Business,” as supplemented
through                  , 20    ; (ii) the Delaware Statutory Trust Act as found in “Delaware Code Annotated, Volume 7A, 2007 Volume -
Michie;” and (iii) as to each of CarMax, the Depositor and the Issuing Entity’s existence in the State of Delaware, a copy of the certificate of formation of each of CarMax and the Depositor and a copy of the certificate of trust of
the Issuing Entity, each as supplied to us by the Secretary of State of the State of Delaware, each of CarMax, the Depositor and the Issuing Entity is a registered organization (as such term is defined in the New York UCC) formed under the laws of
the State of Delaware. For the purposes of this opinion, we have assumed that each of CarMax, the Depositor and the Issuing Entity is organized solely under the laws of the State of Delaware. Each of CarMax, the Depositor and the Issuing Entity is,
therefore, located, for purposes of Article 9 of the New York UCC, in the State of Delaware and the local law of Delaware governs perfection by the filing of a financing statement of a nonpossessory security interest in the Receivables granted by
CarMax, the Depositor and the Issuing Entity. 

  

	2.	Assuming the Receivables are created under, and are evidenced solely by, retail installment sale contracts in the form attached to the Receivables Purchase Agreement as Exhibit B, and assuming they are completed
in their entirety and executed and there is nothing that would prevent them from being enforceable, then the Receivables will constitute “tangible chattel paper” as such term is defined in Article 9 of the New York UCC. 


 

	3.	When each of the Receivables Purchase Agreement and the First Step Bill of Sale has been duly executed and delivered by all parties thereto and when value has been given as provided in Section 9-203(b)(1) of the
New York UCC with respect to the Receivables, the Depositor will have a valid and enforceable security interest in such Receivables and identifiable cash proceeds thereof. When, in addition to the foregoing, the First Step Financing Statement has
been duly filed in the office of the Secretary of State of the State of Delaware, the security interest in favor of the Depositor in such Receivables and identifiable cash proceeds thereof will be perfected. 


 

	4.	 When each of the Receivables Purchase Agreement, the First Step Bill of Sale and the Sale and Servicing Agreement has been duly executed and delivered
by all parties thereto and when value has been given as provided in Section 9-203(b)(1) of the New York UCC with respect to the Receivables, the Issuing Entity will have a valid and enforceable security interest in such Receivables and the
identifiable cash proceeds thereof. When, in addition to the foregoing, each of the First Step Financing Statement and the Second Step Financing 



  
 Ex. E-1 









	 	
Statement has been duly filed in the office of the Secretary of State of the State of Delaware, the security interest in favor of the Issuing Entity in such Receivables and identifiable cash
proceeds thereof will be perfected. 

  

	5.	When each of the Basic Documents has been duly executed and delivered by all parties thereto and when value has been given as provided in Section 9-203(b)(1) of the New York UCC with respect to the Receivables, the
Indenture Trustee will have a valid and enforceable security interest in such Receivables and the identifiable cash proceeds thereof. When, in addition to the foregoing, all of the Financing Statements have been duly filed in the office of the
Secretary of State of the State of Delaware, the security interest in favor of the Indenture Trustee in such Receivables and identifiable cash proceeds thereof will be perfected. 


 

	6.	Under the New York UCC, a nonpossessory security interest in tangible chattel paper can be perfected by the filing of a financing statement only in the jurisdiction where the debtor is located. Because each of CarMax,
the Depositor and the Issuing Entity is located in Delaware for purposes of the New York UCC, Delaware is the only jurisdiction in which a financing statement could be filed to perfect a nonpossessory security interest in the rights of CarMax, the
Depositor and the Issuing Entity in the Receivables. Therefore, to the extent a financing statement was filed there, the office of the Secretary of State of the State of Delaware constitutes the only filing office from which UCC Search Reports must
be reviewed to determine whether another nonpossessory security interest in the rights of CarMax, the Depositor or the Issuing Entity in the Receivables exists which was perfected by filing. We have not reviewed any UCC search reports other than the
UCC Search Reports. 

  

	7.	Based solely on our review of the UCC Search Reports and assuming the Terminated Financing Statements are duly filed in the office of the Secretary of State of the State of Delaware, the respective security interests of
the Depositor, the Issuing Entity and the Indenture Trustee in the Receivables and identifiable cash proceeds thereof are subject to no equal or prior security interest perfected by filing a financing statement under the Delaware UCC. To the extent
the Receivables constitute “tangible chattel paper” under the New York UCC, the local law of the jurisdiction in which the Receivables are physically located governs the effect of perfection or non-perfection and the priority of a
nonpossessory security interest in the Receivables. For purposes of our opinion, we have assumed that the UCC provisions governing the effect of perfection or non-perfection and the priority of nonpossessory security interests in tangible chattel
paper as in effect in each jurisdiction in which the Receivables are physically located, and the interpretation of such provisions in each such jurisdiction, are identical to the corresponding provisions and interpretations under the New York UCC.


  

	8.	 When each of the Basic Documents has been duly executed and delivered by all parties thereto, and value has been given as provided in
Section 9-203(b)(1) of the New York UCC with respect to the Collection Account and the Note Payment Account (collectively, the “Accounts”), the Indenture Trustee will have a valid and enforceable security interest in the
Accounts and the identifiable cash proceeds thereof and such security interest will be perfected under the New York UCC. For the purposes of this opinion, we have also assumed that each Account is a “deposit account” as defined in the New
York UCC, that such Account is maintained with the Indenture Trustee and that the Indenture Trustee is a “bank” 



  
 Ex. E-2 









	 	
as defined in the New York UCC. To the extent each Account constitutes a “securities account” as defined in the New York UCC, and when each of the Financing Statements has been duly
filed in the office of the Secretary of State of the State of Delaware, the security interest of the Indenture Trustee in the Accounts and identifiable cash proceeds thereof has been perfected. 


  
 Ex. E-3
