order to release any remaining portion of the Trust Property to the Seller. 
 SECTION
2.4.      Intention of the Parties. 
 The execution and delivery of this Agreement
shall constitute an acknowledgment by the Seller and the Issuer that they intend that the assignment and transfer herein contemplated constitute a sale and assignment outright, and not for security, of the Receivables and Other Conveyed Property,

ARTICLE III 
 The
Receivables 
 SECTION 3.1.      Representations and Warranties of Seller. 

 (a)    The Seller hereby represents and warrants that each of the representations and warranties
regarding the Receivables that are set forth in Schedule B-1 is true and correct and that the Issuer is deemed to have relied on such representations and warranties in acquiring the Receivables. Such
representations and warranties speak as of the execution and delivery of this Agreement and as of the Closing Date, but shall survive the sale, transfer and assignment of the Receivables to the Issuer and the pledge thereof to the Trust Collateral
Agent pursuant to the Indenture and shall not be waived. 
 (b)    The Seller hereby represents and
warrants that each of the representations and warranties regarding the pool of Receivables that are set forth in Schedule B-2 is true and correct and that the Issuer is deemed to have relied on such
representations and warranties in acquiring the Receivables. Such representations and warranties speak as of the execution and delivery of this Agreement and as of the Closing Date, but shall survive the sale, transfer and assignment of the
Receivables to the Issuer and the pledge thereof to the Trust Collateral Agent pursuant to the Indenture and shall not be waived. 

  
 22 












 (c)    The Seller hereby represents and warrants that
each of the following representations and warranties is true and correct and that the Issuer is deemed to have relied on such representations and warranties in acquiring the Receivables. Such representations and warranties speak as of the execution
and delivery of this Agreement and as of the Closing Date, but shall survive the sale, transfer and assignment of the Receivables to the Issuer and the pledge thereof to the Trust Collateral Agent pursuant to the Indenture and shall not be waived:

 (i)    to the best of the Seller’s knowledge, each Receivable (a) that was
originated by GM Financial was sold by GM Financial to the Seller without any fraud or misrepresentation on the part of GM Financial and (b) that was originated by a Dealer was sold by the Dealer to GM Financial and by GM Financial to the
Seller without any fraud or misrepresentation on the part of such Dealer or GM Financial, respectively; 

(ii)    no Receivable was originated in, or is subject to the laws of, any jurisdiction
the laws of which would make unlawful, void or voidable the sale, transfer and assignment of such Receivable under this Agreement or pursuant to transfers of the Notes; 

(iii)    the Seller has not done anything to convey any right to any Person that would
result in such Person having a right to payments due under the Receivables or otherwise to impair the rights of the Trust, the Trustee, the Trust Collateral Agent and the Noteholders in any Receivable or the proceeds thereof. Other than the security
interest granted to the Trust pursuant to this Agreement and except any other security interests that have been fully released and discharged as of the Closing Date, the Seller has not pledged, assigned, sold, granted a security interest in, or
otherwise conveyed any of the Receivables. The Seller has not authorized the filing of and is not aware of any financing statements against the Seller that include a description of collateral covering the Receivables other than any financing
statement relating to the security interest granted to the Trust hereunder or that has been terminated. The Seller is not aware of any judgment, ERISA or tax lien filings against it; and 

(iv)    no funds have been advanced by the Seller or anyone acting on behalf of GM
Financial in order to cause any Receivable to qualify under the representation and warranty set forth as paragraph 20(E) of Schedule B-1. 

SECTION 3.2.      Repurchase upon Breach. 

(a)    The Seller, the Servicer, the Trust Collateral Agent, the Trustee, the Trust or the Owner Trustee,
as the case may be, shall inform, and any Noteholder may inform, the other parties to this Agreement (or, in the case of notice provided by the Trustee or a Noteholder, all parties of this Agreement) promptly, by notice in writing, upon the
discovery of any breach of the Seller’s representations and warranties made pursuant to Section 3.1(a) that materially and adversely affects the interests of the Noteholders in any Receivable. If Noteholders representing 5% or more of the
Outstanding Amount of the Controlling Class inform the Trust Collateral Agent, by notice in writing, of any breach of the Seller’s representations and warranties made pursuant to Section 3.1(a), the Trust Collateral Agent shall inform
the other parties to this Agreement in the manner specified in the preceding sentence on behalf of such Noteholders. Any such notice delivered by 

  
 23 












 
the Servicer, the Trust Collateral Agent, the Trust, the Trustee, any Noteholder or the Owner Trustee, as the case may be, shall constitute a request by such party that the Seller repurchase the
affected Receivable. As of the last day of the second (or, if the Seller so elects, the first) month following the discovery by the Seller or receipt by the Seller of notice of such breach, unless such breach is cured by such date, the Seller shall
have an obligation to repurchase any Receivable in which the interests of the Noteholders are materially and adversely affected by any such breach as of such date. The “second month” shall mean the month following the month in which
discovery occurs or notice is given, and the “first month” shall mean the month in which discovery occurs or notice is given. In consideration of and simultaneously with the repurchase of the Receivable, the Seller shall remit, or cause GM
Financial to remit, to the Collection Account the Purchase Amount in the manner specified in Section 5.6(a) and the Issuer shall execute such assignments and other documents reasonably requested by such Person in order to effect such
repurchase. The sole remedy of the Issuer, the Owner Trustee, the Trust Collateral Agent, the Trustee or the Noteholders with respect to a breach of representations and warranties pursuant to Section 3.1(a) and the agreement contained in this
Section shall be the repurchase of Receivables pursuant to this Section, subject to the conditions contained herein or to enforce the obligation of GM Financial to the Seller to repurchase such Receivables pursuant to the Purchase Agreement. None of
the Owner Trustee, the Trust Collateral Agent or the Trustee shall have a duty to conduct any affirmative investigation as to the occurrence of any conditions requiring the repurchase of any Receivable pursuant to this Section. 

In addition to the foregoing and notwithstanding whether the related Receivable shall have been purchased by the Seller, the
Seller shall indemnify the Trust, the Trustee, the Trust Collateral Agent and the officers, directors, agents and employees thereof, and the Noteholders against all costs, expenses, losses, damages, claims and liabilities, including reasonable fees
and expenses of counsel, which may be asserted against or incurred by any of them as a result of third-party claims arising out of the events or facts giving rise to such breach. 

(b)    Pursuant to Section 2.1 of this Agreement, the Seller conveyed to the Trust all of the
Seller’s right, title and interest in its rights and benefits, but none of its obligations or burdens, under the Purchase Agreement including the Seller’s rights under the Purchase Agreement and the delivery requirements, representations
and warranties and the cure or repurchase obligations of GM Financial thereunder. The Seller hereby represents and warrants to the Trust that such assignment is valid, enforceable and effective to permit the Trust to enforce such obligations of GM
Financial under the Purchase Agreement. Any purchase by GM Financial pursuant to the Purchase Agreement shall be deemed a purchase by the Seller pursuant to this Section 3.2 and the definition of Purchased Receivable. 

SECTION 3.3.      Custody of Receivable Files. 

(a)    In connection with the sale, transfer and assignment of the Receivables and the Other Conveyed
Property to the Trust pursuant to this Agreement and simultaneously with the execution and delivery of this Agreement, the Trust Collateral Agent hereby revocably appoints the Custodian, and the Custodian hereby accepts such appointment, to act as
the agent of the Trust Collateral Agent as custodian of the following documents or instruments in its possession or control (the “Receivable Files”) which shall be delivered to the Custodian as agent of the Trust Collateral Agent on
or before the Closing Date (with respect to each Receivable): 

  
 24 












 (i)    The fully executed original (or
with respect to “electronic chattel paper”, the authoritative copy) of the Contract; and 

(ii)    The Lien Certificate (when received), and otherwise such documents, if any, that
GM Financial keeps on file in accordance with its customary procedures indicating that the Financed Vehicle is owned by the Obligor and subject to the interest of GM Financial or an Originating Affiliate (which may be accomplished by the use of a
properly registered “doing business as” (“DBA”) name in the applicable jurisdiction) as first lienholder or secured party (including any Lien Certificate received by GM Financial), or, if such Lien Certificate has not yet
been received, a copy of the application therefor or other documentation (which may include a dealer guaranty) that indicates that GM Financial has commenced procedures that will result in such Lien Certificate showing GM Financial or an Originating
Affiliate (which may be accomplished by the use of a properly registered DBA name in the applicable jurisdiction) as secured party. 

The Receivable Files are constructively delivered to the Trust Collateral Agent, as pledgee of the Issuer pursuant to the
Indenture, and the Custodian hereby, as of the Closing Date, acknowledges receipt of the Receivable File for each Receivable listed in Schedule A hereto. No initial review or any periodic review of the Receivable Files by the Issuer, the Owner
Trustee, the Trustee or the Trust Collateral Agent is required. 
 (b)    If the Trust Collateral Agent,
or its agent, as the case may be, is acting as the Custodian pursuant to Section 3.12, the Trust Collateral Agent, or its agent, as the case may be, shall be deemed to have assumed the obligations of the Custodian (except for any liabilities
incurred by the predecessor Custodian) specified in this Agreement until such time as a successor Custodian has been appointed. Upon payment in full of any Receivable, the Servicer will notify the Custodian pursuant to a certificate of an officer of
the Servicer (which certificate shall include a statement to the effect that all amounts received in connection with such payments which are required to be deposited in the Collection Account pursuant to Section 4.1 have been so deposited) and
shall request delivery of the Receivable and Receivable File to the Servicer; provided, that, no such certificate will be required to be delivered for so long as GM Financial is the Servicer. Upon the sale of any Receivable pursuant to
Section 4.3(c), the Servicer (if GM Financial is not the Servicer) will notify the Custodian pursuant to a certificate of an officer of the Servicer (which certificate shall include a statement to the effect that all amounts received in
connection with such sale which are required to be deposited in the Collection Account pursuant to Section 4.3(c) have been so deposited) and shall request delivery of the Receivable and Receivable File to the purchaser of such Receivable. From
time to time as appropriate for servicing and enforcing any Receivable, the Custodian shall, upon written request of an officer of the Servicer and delivery to the Custodian of a receipt signed by such officer, cause the original Receivable and the
related Receivable File to be released to the Servicer; provided, that, no such written request shall be required for so long as GM Financial is the Servicer. The Servicer’s receipt of a Receivable and/or Receivable File shall
obligate the Servicer to return the original Receivable and the related Receivable File to the Custodian when its need by the Servicer has ceased unless the Receivable is repurchased as described in Section 3.2, 4.2, 4.4(c) or 4.7. 

(c)    The authoritative copy of each Contract that constitutes or evidences a Receivable which is
“electronic chattel paper” (within the meaning of the UCC) will be maintained by an 

  
 25 












 
Electronic Chattel Paper Sub-Custodian on behalf of the Custodian for the benefit of the Trust Collateral Agent. The Custodian will confirm that the
authoritative copy of each Contract that constitutes or evidences a Receivable which is “electronic chattel paper” does not have any marks or notations indicating it has been pledged, assigned or otherwise conveyed to any Person other than
the Trust Collateral Agent. The Custodian will confirm that each Contract which is “electronic chattel paper” has been established in a manner such that (i) all copies or revisions that add or change an identified assignee of the
authoritative copy of each such Contract must be made with the participation of the Custodian on behalf of the Trust Collateral Agent and (ii) all revisions of the authoritative copy of each such Contract must be readily identifiable as an
authorized or unauthorized revision. 
 (d)    The Servicer hereby agrees that upon any appointment of a
successor Servicer hereunder it shall take all necessary action to transfer all of its control of any Receivables consisting of electronic chattel paper to the applicable successor Servicer (including the transfer of such electronic chattel paper to
a separate electronic vault at each Electronic Chattel Paper Sub-Custodian controlled by such successor Servicer or to a separate electronic vault at such successor Servicer or export of the electronic chattel
paper from the applicable electronic vault and delivery of physical copies of exported Contracts to the successor Servicer). 

(e)    In its capacity as Custodian, the Servicer confirms that it is acting solely as agent of the Trust
Collateral Agent with respect to the Receivables which are electronic chattel paper. 
 SECTION
3.4.      Maintenance and Safekeeping of the Receivable Files. The Custodian will accurately maintain and keep current the Receivable Files, including any computer systems on which the Receivable Files are
electronically stored, all in a manner that will permit the Servicer and the Issuer to comply with this Agreement and the Trust Collateral Agent to comply with the Indenture. The Custodian will act with reasonable care, using that degree of
skill and attention that the Custodian would exercise with respect to files relating to comparable automotive or other receivables that it services or holds for itself or others. The Custodian shall promptly report to the Trust Collateral Agent
in writing any failure on its part to hold the Receivable Files and maintain its accounts, records and computer systems as herein provided and promptly take appropriate action to remedy any such failure.

SECTION 3.5.      Location of Receivable Files. The Custodian will maintain the
Receivable Files in the United States in such a manner as to permit retrieval thereof and access thereto in the manner contemplated by this Agreement. The Custodian’s records will at all times indicate that it is holding the Receivable Files on
behalf of the Trust, separate from any other instruments and files that it holds. 
 SECTION
3.6.      Access to Records. The Custodian shall, subject only to the Custodian’s security requirements applicable to its own employees and agents having access to similar records held by the Custodian,
which requirements shall be consistent with the practices it exercises with respect to similar files and records relating to comparable automotive or other receivables that it holds for itself or others, and at such times as may be reasonably
imposed by the Custodian, permit only the Noteholders and the Trust Collateral Agent or their duly authorized representatives, attorneys or auditors to inspect, at the Servicer’s expense, the Receivable Files and the related


  
 26 












 
accounts, records, and computer systems maintained by the Custodian pursuant hereto at such times as the Noteholders or the Trust Collateral Agent may reasonably request. 

SECTION 3.7.      Advice of Counsel. The Custodian shall be entitled to rely and act upon
advice of counsel with respect to its performance hereunder as Custodian and shall be without liability for any action reasonably taken pursuant to such advice, provided that such action is not in violation of applicable federal or State law. 

SECTION 3.8.      Administration; Reports. The Custodian shall, in general, attend to all
non-discretionary details in connection with maintaining custody of the Receivable Files on behalf of the Trust Collateral Agent. In addition, the Custodian shall assist the Trust Collateral Agent
generally in the preparation of any routine reports to Noteholders or to regulatory bodies, to the extent necessitated by the Custodian’s custody of the Receivable Files. 

SECTION 3.9.      Instructions; Authority to Act. The Custodian shall be deemed to have
received proper instructions with respect to the Receivable Files upon its receipt of written instructions signed by a Responsible Officer of the Trust Collateral Agent. Such instructions may be general or specific in terms. A copy of any such
instructions shall be furnished by the Trust Collateral Agent to the Trustee (if they are separate entities) and the Issuer. 

SECTION 3.10.    Custodian Fee. For its services under this Agreement, the Custodian shall be
entitled to reasonable compensation to be paid by the Servicer. 
 SECTION 3.11.    Indemnification
by the Custodian. The Custodian agrees to indemnify the Issuer, the Owner Trustee, the Trust Collateral Agent and the Trustee for any and all liabilities, obligations, losses, damage, payments, costs or expenses of any kind whatsoever (including
the fees and expenses of counsel) that may be imposed on, incurred or asserted against the Issuer, the Owner Trustee, the Trust Collateral Agent and the Trustee and their respective officers, directors, employees, agents, attorneys and successors
and assigns as the result of any act or omission in any way relating to the maintenance and custody by the Custodian of the Receivable Files; provided, however, that the Custodian shall not be liable for any portion of any such liabilities,
obligations, losses, damages, payments or costs or expenses due to the Issuer’s, the Owner Trustee’s, the Trust Collateral Agent’s or the Trustee’s or the officers’, directors’, employees’ and agents’ thereof
own willful misfeasance, bad faith or gross negligence. In no event shall the Custodian be liable to any third party for acts or omissions of the Custodian. 

SECTION 3.12.    Effective Period and Termination of Custodian. GM Financial’s appointment as
Custodian is effective as of the Cutoff Date and will continue until terminated pursuant to this Section 3.12. So long as GM Financial is serving as Custodian, any termination of GM Financial as Servicer hereunder shall terminate GM
Financial as Custodian. As soon as practicable after termination of its appointment as Custodian, the Custodian shall deliver, at the Custodian’s expense, the Receivable Files to the Trust Collateral Agent on behalf of the Noteholders at such
place or places as the Trust Collateral Agent may designate, and the Trust Collateral Agent, or its agent, as the case may be, shall act as Custodian for such Receivable Files on behalf of the Noteholders until such time as a successor custodian has
been appointed. If, within seventy-two (72) hours after the termination of this Agreement, the Custodian has not delivered 

  
 27 












 
the Receivable Files in accordance with the preceding sentence, the Trust Collateral Agent may enter the premises of the Custodian and remove the Receivable Files from such premises. 

SECTION 3.13.      Dispute Resolution. 

(a)    If the Servicer, the Trust, the Owner Trustee, the Trustee, the Trust Collateral Agent, a
Noteholder or the Trust Collateral Agent on behalf of certain Noteholders in accordance with the following sentence (the “Requesting Party”) requests that the Seller and/or GM Financial repurchase a Receivable due to an alleged
breach of a representation and warranty in Section 5.1 of the Purchase Agreement or in Section 3.2(a) hereof (each, a “Repurchase Request”), and the Repurchase Request has not been resolved within one hundred eighty
(180) days of the receipt of notice of the Repurchase Request by the Seller or GM Financial, as the case may be (which resolution may take the form of a repurchase of the related Receivable by the Seller or GM Financial, as applicable, a
withdrawal of the related Repurchase Request by the related Requesting Party or a cure of the condition that led to the related breach in the manner set forth herein or in the Purchase Agreement, as applicable), the Requesting Party may refer the
matter, in its sole discretion, to either mediation (including non-binding arbitration) or binding third-party arbitration. Noteholders representing 5% or more of the Outstanding Amount of the Controlling
Class may direct the Trust Collateral Agent, by notice in writing, in relation to any matter described in the preceding sentence, to initiate either mediation (including non-binding arbitration) or
binding third-party arbitration, as directed by such Noteholders, on behalf of such Noteholders. The Requesting Party must start the mediation or arbitration proceeding according to the ADR Rules of the ADR Organization within ninety (90) days
following the date on which the Form 10-D is filed that relates to the Collection Period during which the related 180-day period ended. The Seller and GM Financial agree
to participate in the dispute resolution method selected by the Requesting Party. 
 (b)    If the
Requesting Party selects mediation for dispute resolution: 
 (i)    The mediation will
be administered by the ADR Organization using its ADR Rules. However, if any ADR Rules are inconsistent with the procedures for mediation stated in this Section 3.13(b), the procedures in this Section 3.13(b) will control. 

(ii)    A single mediator will be selected by the ADR Organization from a list of neutrals
maintained by it according to the ADR Rules. The mediator must be impartial, an attorney admitted to practice in the State of New York and have at least fifteen (15) years of experience in commercial litigation and, if possible, consumer
finance or asset-backed securitization matters. 
 (iii)    The mediation will start
within fifteen (15) Business Days after the selection of the mediator and conclude within thirty (30) days after the start of the mediation. 

(iv)    Expenses of the mediation will be allocated to the parties as mutually agreed by
them as part of the mediation. 
 (v)    If the parties fail to agree at the completion
of the mediation, the Requesting Party may refer the Repurchase Request to arbitration under this Section 3.13. 

  
 28 












 (c)    If the Requesting Party selects arbitration for
dispute resolution: 
 (i)    The arbitration will be administered by the ADR
Organization using its ADR Rules. However, if any ADR Rules are inconsistent with the procedures for arbitration stated in this Section 3.13(c), the procedures in this Section 3.13(c) will control. 

(ii)    A single arbitrator will be selected by the ADR Organization from a list of
neutrals maintained by it according to the ADR Rules. The arbitrator must be an attorney admitted to practice in the State of New York and have at least fifteen (15) years of experience in commercial litigation and, if possible, consumer
finance or asset-backed securitization matters. The arbitrator will be independent and impartial and will comply with the Code of Ethics for Arbitrators in Commercial Disputes in effect at the time of the arbitration. Before accepting an
appointment, the arbitrator must promptly disclose any circumstances likely to create a reasonable inference of bias or conflict of interest or likely to preclude completion of the proceedings within the stated time
schedule.    The arbitrator may be removed by the ADR Organization for cause consisting of actual bias, conflict of interest or other serious potential for conflict. 

(iii)    The arbitrator will have the authority to schedule, hear and determine any
motions, according to New York law, and will do so at the motion of any party. Discovery will be completed with thirty (30) days of selection of the arbitrator and will be limited for each party to two (2) witness depositions not to exceed
five (5) hours, two (2) interrogatories, one (1) document request and one (1) request for admissions. However, the arbitrator may grant additional discovery on a showing of good cause that the additional discovery is reasonable
and necessary. Briefs will be limited to no more than ten (10) pages each, and will be limited to initial statements of the case, motions and a pre-hearing brief. The evidentiary hearing on the merits
will start no later than sixty (60) days after selection of the arbitrator and will proceed for no more than six (6) consecutive Business Days with equal time allocated to each party for the presentation of evidence and cross examination.
The arbitrator may allow additional time for discovery and hearings on a showing of good cause or due to unavoidable delays. 

(iv)    The arbitrator will make its final determination no later than ninety
(90) days after its selection. The arbitrator will resolve the dispute according to the terms of this Agreement and the Basic Documents, and may not modify or change this Agreement or the Basic Documents in any way. The arbitrator will not have
the power to award punitive damages or consequential damages in any arbitration conducted by them. In its final determination, the arbitrator will determine and award the expenses of the arbitration (including filing fees, the fees of the
arbitrator, expense of any record or transcript of the arbitration and administrative fees) to the parties in its reasonable discretion. The determination of the arbitrator will be in writing and counterpart copies will be promptly delivered to the
parties. The determination will be final and non-appealable, except for actions to confirm or vacate the determination permitted under federal or State law, and may be entered and enforced in any court of
competent jurisdiction. 
 (v)    By selecting arbitration, the Requesting Party is
giving up the right to sue in court, including the right to a trial by jury. 

  
 29 












 (vi)    The Requesting Party may not
bring a putative or certificated class action to arbitration. If this waiver of class action rights is found to be unenforceable for any reason, the Requesting Party agrees that it will bring its claims in a court of competent jurisdiction. 

(d)    For each mediation or arbitration: 

(i)    Any mediation or arbitration will be held in New York, New York at the offices of
the mediator or arbitrator or at another location selected by the Seller or GM Financial. Any party or witness may participate by teleconference or video conference. 

(ii)    The Seller, GM Financial and the Requesting Party will have the right to seek
provisional relief from a competent court of law, including a temporary restraining order, preliminary injunction or attachment order, if such relief is available by law. 

(iii)    Neither the Seller nor GM Financial will be required to produce personally
identifiable customer information for purposes of any mediation or arbitration. The existence and details of any unresolved Repurchase Request, any informal meetings, mediations or arbitration proceedings, the nature and amount of any relief sought
or granted, any offers or statements made and any discovery taken in the proceeding will be confidential, privileged and inadmissible for any purpose in any other mediation, arbitration, litigation or other proceeding. The parties will keep this
information confidential and will not disclose or discuss it with any third party (other than a party’s attorneys, experts, accountants and other advisors, as reasonably required in connection with the mediation or arbitration proceeding under
this Section 3.13), except as required by law, regulatory requirement or court order. If a party to a mediation or arbitration proceeding receives a subpoena or other request for information from a third party (other than a governmental
regulatory body) for confidential information of the other party to the mediation or arbitration proceeding, the recipient will promptly notify the other party and will provide the other party with the opportunity to object to the production of its
confidential information. 
 ARTICLE IV 

Administration and Servicing of Receivables 

SECTION 4.1.      Duties of the Servicer. The Servicer is hereby authorized to act as
agent for the Trust and in such capacity shall manage, service, administer and make collections on the Receivables, and perform the other actions required by the Servicer under this Agreement. The Servicer agrees that its servicing of the
Receivables shall be carried out in accordance with customary and usual procedures of institutions which service motor vehicle retail installment sale contracts or promissory notes and, to the extent more exacting, the degree of skill and attention
that the Servicer exercises from time to time with respect to all comparable motor vehicle receivables that it services for itself or others. In performing such duties, so long as GM Financial is the Servicer, it shall substantially comply with the
Servicing Policies and Procedures. The Servicer’s duties shall include, without limitation, collecting and posting all payments, responding to inquiries of Obligors on the Receivables, investigating delinquencies, sending payment invoices


  
 30 












 
to Obligors, reporting any required tax information to Obligors, monitoring the Collateral, accounting for collections and furnishing monthly and annual statements to the Trust Collateral Agent
and the Trustee with respect to distributions, and performing the other duties specified herein. 
 The Servicer, or if GM
Financial is no longer the Servicer, GM Financial, at the request of the Servicer, shall also administer and enforce all rights and responsibilities of the holder of the Receivables provided for in the Dealer Agreements (and shall maintain
possession of the Dealer Agreements, to the extent it is necessary to do so), the Dealer Assignments and the Insurance Policies, to the extent that such Dealer Agreements, Dealer Assignments and Insurance Policies relate to the Receivables, the
Financed Vehicles or the Obligors. To the extent consistent with the standards, policies and procedures otherwise required hereby, the Servicer shall follow its customary standards, policies, and procedures and shall have full power and authority,
acting alone, to do any and all things in connection with such managing, servicing, administration and collection that it may deem necessary or desirable. Without limiting the generality of the foregoing, the Servicer is hereby authorized and
empowered by the Trust to execute and deliver, on behalf of the Trust, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge, and all other comparable instruments, with respect to the Receivables and
with respect to the Financed Vehicles; provided, however, that notwithstanding the foregoing, the Servicer shall not, except pursuant to an order from a court of competent jurisdiction, release an Obligor from payment of any unpaid amount
under any Receivable or waive the right to collect the unpaid balance of any Receivable from the Obligor, except in accordance with the Servicer’s customary practices. 

The Servicer is hereby authorized to commence, in its own name or in the name of the Trust, a legal proceeding to enforce a
Receivable pursuant to Section 4.3 or to commence or participate in any other legal proceeding (including, without limitation, a bankruptcy proceeding) relating to or involving a Receivable, an Obligor or a Financed Vehicle. If the Servicer
commences or participates in such a legal proceeding in its own name, the Trust shall thereupon be deemed to have automatically assigned such Receivable to the Servicer solely for purposes of commencing or participating in any such proceeding as a
party or claimant, and the Servicer is authorized and empowered by the Trust to execute and deliver in the Servicer’s name any notices, demands, claims, complaints, responses, affidavits or other documents or instruments in connection with any
such proceeding. The Trust Collateral Agent and the Owner Trustee shall furnish the Servicer with any limited powers of attorney and other documents which the Servicer may reasonably request and which the Servicer deems necessary or appropriate and
take any other steps which the Servicer may deem necessary or appropriate to enable the Servicer to carry out its servicing and administrative duties under this Agreement. 

As set forth in Section 9.3, in the event the Servicer fails to perform its obligations hereunder, the successor Servicer
shall be responsible for the Servicer’s duties in this Agreement as if it were the Servicer, provided that the successor Servicer shall not be liable for the Servicer’s breach of its obligations. 

  
 31 












 SECTION 4.2.      Collection of Receivable
Payments; Modifications of Receivables. 
 (a)    Consistent with the standards, policies and
procedures required by this Agreement, the Servicer shall make reasonable efforts to collect all payments called for under the terms and provisions of the Receivables as and when the same shall become due, and shall follow such collection procedures
as it follows with respect to all comparable automobile receivables that it services for itself or others and otherwise act with respect to the Receivables, the Dealer Agreements, the Dealer Assignments, the Insurance Policies and the Other Conveyed
Property in such manner as will, in the reasonable judgment of the Servicer, maximize the amount to be received by the Trust with respect thereto, including directing the Issuer to sell the Receivables pursuant to Section 4.3(c). The Servicer
is authorized in its discretion to waive any prepayment charge, late payment charge or any other similar fees that may be collected in the ordinary course of servicing any Receivable. 

(b)    The Servicer may grant extensions, rebates, deferrals, amendments, modifications or adjustments
with respect to any Receivable in accordance with its Servicing Policies and Procedures; provided, however, that if the Servicer (i) extends a Receivable beyond the Collection Period immediately preceding the latest Final
Scheduled Distribution Date, or (ii) reduces the Amount Financed or APR with respect to any Receivable, it will repurchase such Receivable in the manner provided in Section 3.2 if such change in the Receivable would materially and
adversely affect the interests of the Noteholders, unless the Servicer is required to take such action by law (including, without limitation, by the Servicemembers Civil Relief Act) or court order. 

(c)    Subject to the proviso of the first sentence in Section 4.2(b), the Servicer or its Affiliates
may engage in any marketing practice or promotion of any sale of any products, goods or services to Obligors with respect to the Receivables so long as such practices, promotions or sales are offered to obligors of comparable motor vehicle
receivables serviced by the Servicer for itself and others, whether or not such practices, promotions or sales might result in a decrease in the aggregate amount of payments on the Receivables, prepayments or faster or slower timing of the payment
of the Receivables. 
 (d)    The Servicer shall remit all payments by or on behalf of the Obligors
received directly by the Servicer to the Collection Account as soon as practicable, but in no event later than the second Business Day after receipt thereof; provided, however, that if the Monthly Remittance Condition is satisfied,
then the Servicer shall not be required to deposit into the Collection Account all payments by or on behalf of the Obligors received directly by the Servicer until noon, New York City time, on the Business Day prior to the Distribution Date
immediately following receipt thereof. For purposes of the preceding sentence, “receipt” of a payment shall mean the initial deposit thereof in the Servicer’s bank account. 

(e)    [Reserved] 

(f)    GM Financial shall not cause or permit the substitution of the Financed Vehicle relating to a
Receivable unless: (i) the substitution is a replacement of the Financed Vehicle originally financed under the related Receivable; (ii) the Financed Vehicle originally financed under the related Receivable was either (x) insured under
an Insurance Policy as required under Section 4.4(a) at the time of a casualty loss that is treated as a total loss under such Insurance Policy, (y) 

  
 32 












 
deemed to be a “lemon” pursuant to applicable State law and repurchased by the related Dealer or (z) the subject of an order by a court of competent jurisdiction directing GM
Financial to substitute another vehicle under the related Receivable; (iii) the related Receivable is not more than thirty (30) days delinquent; (iv) the Obligor is deemed to be in “good standing” by the Servicer and is not
in breach of any requirement under the related Receivable; (v) the replacement Financed Vehicle has a book value (N.A.D.A.) at least equal to the book value (N.A.D.A.) of the Financed Vehicle that is being replaced, measured immediately before
the casualty loss or replacement by the Dealer and (vi) as of the date of such substitution, the replacement Financed Vehicle’s mileage is no greater than the mileage on the Financed Vehicle that is being replaced; provided,
however, that if the substitution is made pursuant to clause (ii)(z), above, clauses (iii) through (vi) inclusive, shall not be applicable. GM Financial shall not cause or permit the substitution of Financed Vehicles relating to Receivables
having an original aggregate Principal Balance greater than 2% of the Original Pool Balance, (the “Substitution Limit”). In the event that the Substitution Limit is exceeded for any reason, (i) GM Financial shall, on or before
the next following Accounting Date, repurchase a sufficient number of such Receivables to cause the aggregate original Principal Balances of such Receivables to be less than the Substitution Limit or (ii) if GM Financial is not the Servicer and
the Servicer has caused substitutions to be made hereunder pursuant to the circumstances described in clause (ii)(x), above, the Servicer shall, on or before the next following Accounting Date, repurchase a sufficient number of such Receivables to
cause the aggregate original Principal Balances of such Receivables to be less than the Substitution Limit. 
 SECTION
4.3.      Realization upon Receivables. 
 (a)    In
addition to the Servicer’s ability to direct the Issuer to sell Receivables pursuant to Section 4.3(c), and consistent with the standards, policies and procedures required by this Agreement, the Servicer shall use its best efforts to
repossess (or otherwise comparably convert the ownership of) and liquidate any Financed Vehicle securing a Receivable with respect to which the Servicer has determined that payments thereunder are not likely to be resumed, as soon as is practicable;
provided, however, that the Servicer may elect not to repossess a Financed Vehicle if in its good faith judgment it determines that the proceeds ultimately recoverable with respect to such Receivable would be increased by forbearance or if it
instead elects to direct the Issuer to sell the Receivables pursuant to Section 4.3(c). The Servicer is authorized to follow such customary practices and procedures as it shall deem necessary or advisable, consistent with the standard of care
required by Section 4.1, which practices and procedures may include reasonable efforts to realize upon any recourse to Dealers, the sale of the related Financed Vehicle at public or private sale, the submission of claims under an Insurance
Policy and other actions by the Servicer in order to realize upon such a Receivable. The foregoing is subject to the provision that, in any case in which the Financed Vehicle shall have suffered damage, the Servicer shall not expend funds in
connection with any repair or towards the repossession of such Financed Vehicle unless it expects in its sole discretion, that such repair and/or repossession shall increase the proceeds of liquidation of the related Receivable by an amount greater
than the amount of such expenses. All amounts received upon liquidation of a Financed Vehicle shall be remitted directly by the Servicer to the Collection Account without deposit into any intervening account as soon as practicable, but in no event
later than the Business Day after receipt thereof (or, if the Monthly Remittance Condition is satisfied, by no later than noon, New York City time, on the Business Day prior to the Distribution Date immediately following receipt thereof). The
Servicer shall be entitled to recover all reasonable expenses incurred by it in the course of repossessing and liquidating a Financed Vehicle 

  
 33 












 
into cash proceeds, but only out of the cash proceeds of such Financed Vehicle, any deficiency obtained from the Obligor or any amounts received from the related Dealer, which amounts in
reimbursement may be retained by the Servicer (and shall not be required to be deposited as provided in Section 4.2(d)) to the extent of such expenses. The Servicer shall pay on behalf of the Trust any personal property taxes assessed on
repossessed Financed Vehicles. The Servicer shall be entitled to reimbursement of any such tax from Net Liquidation Proceeds with respect to such Receivable. 

(b)    If the Servicer, or if GM Financial is no longer the Servicer, GM Financial at the request of the
Servicer, elects to commence a legal proceeding to enforce a Dealer Agreement or Dealer Assignment, the act of commencement shall be deemed to be an automatic assignment from the Trust to the Servicer, or to GM Financial at the request of the
Servicer, of the rights under such Dealer Agreement or Dealer Assignment for purposes of collection only. If, however, in any enforcement suit or legal proceeding it is held that the Servicer or GM Financial, as appropriate, may not enforce a Dealer
Agreement or Dealer Assignment on the grounds that it is not a real party in interest or a Person entitled to enforce the Dealer Agreement or Dealer Assignment, the Owner Trustee and/or the Trust Collateral Agent, at GM Financial’s expense, or
the Seller, at the Seller’s expense, shall take such steps as the Servicer deems reasonably necessary to enforce the Dealer Agreement or Dealer Assignment, including bringing suit in its name or the name of the Seller or of the Trust and the
Owner Trustee and/or the Trust Collateral Agent for the benefit of the Noteholders. All amounts recovered shall be remitted directly by the Servicer as provided in Section 4.2(d). 

(c)    Consistent with the standards, policies and procedures required by this Agreement, the Servicer may
use its best efforts to locate a third-party purchaser that is not affiliated with the Servicer, the Seller or the Issuer to purchase from the Issuer any Receivable that has become more than sixty (60) days delinquent, and shall have the right
to direct the Issuer to sell any such Receivable to the third-party purchaser; provided, that no more than 20% of the number of Receivables in the pool as of the Cutoff Date may be sold by the Issuer pursuant to this Section 4.3(c) in
the aggregate; provided further, that the Servicer may elect to not direct the Issuer to sell a Receivable that has become more than sixty (60) days delinquent if in its good faith judgment the Servicer determines that the proceeds
ultimately recoverable with respect to such Receivable would be increased by forbearance. In selecting Receivables to be sold to a third-party purchaser pursuant to this Section 4.3(c), the Servicer shall use commercially reasonable efforts to
locate purchasers for the most delinquent Receivables first. In any event, the Servicer shall not use any procedure in selecting Receivables to be sold to third-party purchasers which is materially adverse to the interest of the Noteholders. The
Issuer shall sell each Sold Receivable for the greatest market price possible; provided, however, that aggregate Sale Amounts received by the Issuer for all Receivables sold to a single third-party purchaser on a single date must be at least
equal to the sum of the Minimum Sale Prices for all such Receivables. The Servicer shall remit or cause the third-party purchaser to remit all sale proceeds from the sale of Receivables to the Collection
Account without deposit into any intervening account as soon as practicable, but in no event later than the Business Day after receipt thereof. 

  
 34 












 SECTION 4.4.      Insurance. 

(a)    The Servicer shall require, in accordance with the Servicing Policies and Procedures, that each
Financed Vehicle be insured by the related Obligor under the Insurance Policies referred to in paragraph 18 of Schedule B-1 hereto. Each Receivable requires the Obligor to maintain such physical loss and
damage insurance, naming GM Financial or an Originating Affiliate (which may be accomplished by the use of a properly registered DBA name in the applicable jurisdiction) and its successors and assigns as additional insureds, and permits the holder
of such Receivable to obtain physical loss and damage insurance at the expense of the Obligor if the Obligor fails to maintain such insurance. If the Servicer shall determine that an Obligor has failed to obtain or maintain a physical loss and
damage Insurance Policy covering the related Financed Vehicle which satisfies the conditions set forth in such paragraph 18 (including, without limitation, during the repossession of such Financed Vehicle) the Servicer may enforce the rights of the
holder of the Receivable under the Receivable to require the Obligor to obtain such physical loss and damage insurance in accordance with the Servicing Policies and Procedures. The Servicer may maintain a vendor’s single interest or other
collateral protection insurance policy with respect to all Financed Vehicles (“Collateral Insurance”) which policy shall by its terms insure against physical loss and damage in the event any Obligor fails to maintain physical loss
and damage insurance with respect to the related Financed Vehicle. The Servicer shall cause itself or an Originating Affiliate, and may cause the Trust Collateral Agent (which may be accomplished by the use of a properly registered DBA name in the
applicable jurisdiction), to be named as named insured under all policies of Collateral Insurance. Costs incurred by the Servicer in maintaining such Collateral Insurance shall be paid by the Servicer. 

(b)    The Servicer may, if an Obligor fails to obtain or maintain a physical loss and damage Insurance
Policy, obtain insurance with respect to the related Financed Vehicle and advance on behalf of such Obligor, as required under the terms of the Insurance Policy, the premiums for such insurance (such insurance being referred to herein as
“Force-Placed Insurance”). All policies of Force-Placed Insurance shall be endorsed with clauses providing for loss payable to the Servicer. Any cost incurred by the Servicer in maintaining such Force-Placed Insurance shall only be
recoverable out of premiums paid by the Obligors or Net Liquidation Proceeds with respect to the Receivable, as provided in Section 4.4(c). 

(c)    In connection with any Force-Placed Insurance obtained hereunder, the Servicer may, in the manner
and to the extent permitted by applicable law, require the Obligors to repay the entire premium to the Servicer. In no event shall the Servicer include the amount of the premium in the Amount Financed under the Receivable. For all purposes of this
Agreement, the Insurance Add-On Amount with respect to any Receivable having Force-Placed Insurance will be treated as a separate obligation of the Obligor and will not be added to the Principal Balance of
such Receivable, and amounts allocable thereto will not be available for distribution on the Notes and the Certificate. The Servicer shall retain and separately administer the right to receive payments from Obligors with respect to Insurance Add-On Amounts or rebates of Forced-Placed Insurance premiums. If an Obligor makes a payment with respect to a Receivable having Force-Placed Insurance, but the Servicer is unable to determine whether the payment is
allocable to the Receivable or to the Insurance Add-On Amount, the payment shall be applied first to any unpaid Scheduled Receivables Payments and then to the Insurance
Add-On Amount. Net Liquidation Proceeds on any Receivable will be used first to pay the Principal Balance and accrued interest on 

  
 35 












 
such Receivable and then to pay the related Insurance Add-On Amount. If an Obligor under a Receivable with respect to which the Servicer has placed
Force-Placed Insurance fails to make scheduled payments of such Insurance Add-On Amount as due, and the Servicer has determined that eventual payment of the Insurance
Add-On Amount is unlikely, the Servicer may, but shall not be required to, purchase such Receivable from the Trust for the Purchase Amount on any subsequent Determination Date. Any such Receivable, and any
Receivable with respect to which the Servicer has placed Force-Placed Insurance which has been paid in full (excluding any Insurance Add-On Amounts) will be assigned to the Servicer. 

(d)    The Servicer may sue to enforce or collect upon the Insurance Policies, in its own name, if
possible, or as agent of the Trust. If the Servicer elects to commence a legal proceeding to enforce an Insurance Policy, the act of commencement shall be deemed to be an automatic assignment of the rights of the Trust under such Insurance Policy to
the Servicer for purposes of collection only. If, however, in any enforcement suit or legal proceeding it is held that the Servicer may not enforce an Insurance Policy on the grounds that it is not a real party in interest or a holder entitled to
enforce the Insurance Policy, the Issuer and/or the Trust Collateral Agent, at the Servicer’s expense, or the Seller, at the Seller’s expense, shall take such steps as the Servicer deems necessary to enforce such Insurance Policy,
including bringing suit in its name or the name of the Trust and the Owner Trustee and/or the Trust Collateral Agent for the benefit of the Noteholders. 

SECTION 4.5.      Maintenance of Security Interests in Vehicles. 

(a)    Consistent with the policies and procedures required by this Agreement, the Servicer shall take
such steps on behalf of the Trust as are necessary to maintain perfection of the security interest created by each Receivable in the related Financed Vehicle, including, but not limited to, obtaining the execution by the Obligors and the recording,
registering, filing, re-recording, re-filing, and re-registering of all security agreements, financing statements and
continuation statements as are necessary to maintain the security interest granted by the Obligors under the respective Receivables. The Trust Collateral Agent hereby authorizes the Servicer, and the Servicer agrees, to take any and all steps
necessary to re-perfect such security interest on behalf of the Trust as necessary because of the relocation of a Financed Vehicle or for any other reason. In the event that the assignment of a Receivable to
the Trust is insufficient, without a notation on the related Financed Vehicle’s certificate of title, or without fulfilling any additional administrative requirements under the laws of the State in which the Financed Vehicle is located, to
perfect a security interest in the related Financed Vehicle in favor of the Trust, the Servicer hereby agrees that the designation of GM Financial or an Originating Affiliate (which may be accomplished by the use of a properly registered DBA name in
the applicable jurisdiction) as the secured party on the Lien Certificate is in its capacity as Servicer as agent of the Trust. 

(b)    Upon the occurrence of a Servicer Termination Event, the Servicer or the successor Servicer (if no
successor Servicer has been appointed, then the Trust Collateral Agent) shall take or cause to be taken such action as may, in the Opinion of Counsel to the Majority Noteholders, be necessary to perfect or
re-perfect the security interests in the Financed Vehicles securing the Receivables in the name of the Trust by amending the title documents of such Financed Vehicles or by such other reasonable means as may,
in the Opinion of Counsel to the Majority Noteholders, be necessary or prudent. 

  
 36 












 GM Financial hereby agrees to pay all expenses related to such perfection or
reperfection and to take all action necessary therefor. GM Financial hereby appoints the Trust Collateral Agent as its attorney-in-fact to take any and all steps
required to be performed by GM Financial pursuant to this Section 4.5(b) (it being understood that and agreed that the Trust Collateral Agent shall have no obligation to take such steps with respect to all perfection or reperfection, except as
pursuant to the Basic Documents to which it is a party and to which GM Financial has paid all expenses), including execution of Lien Certificates or any other documents in the name and stead of GM Financial (which may be accomplished by the use of a
properly registered DBA name in the applicable jurisdiction), and the Trust Collateral Agent hereby accepts such appointment. 

SECTION 4.6.      Covenants of Servicer. By its execution and delivery of this Agreement,
the Servicer makes the following covenants on which the Trust Collateral Agent relies in accepting the Receivables and on which the Trustee relies in authenticating the Notes. 

(a)      The Servicer covenants as follows: 

(i)    Liens in Force. The Financed Vehicle securing each Receivable shall not be
released in whole or in part from the security interest granted by the Receivable, except upon payment in full of the Receivable or as otherwise contemplated herein; 

(ii)    No Impairment. The Servicer shall do nothing to impair the rights of the
Trust or the Noteholders in the Receivables, the Dealer Agreements, the Dealer Assignments, the Insurance Policies or the Other Conveyed Property except as otherwise expressly provided herein; 

(iii)    No Amendments. The Servicer shall not extend or otherwise amend the terms
of any Receivable, except in accordance with Section 4.2; and 

(iv)    Restrictions on Liens. The Servicer shall not (A) create, incur or
suffer to exist, or agree to create, incur or suffer to exist, or consent to cause or permit in the future (upon the happening of a contingency or otherwise) the creation, incurrence or existence of any Lien or restriction on transferability of the
Receivables except for the Lien in favor of the Trust Collateral Agent for the benefit of the Noteholders and the restrictions on transferability imposed by this Agreement or (B) sign or file under the UCC of any jurisdiction any financing
statement which names GM Financial or the Servicer as a debtor, or sign any security agreement authorizing any secured party thereunder to file such financing statement, with respect to the Receivables, except in each case any such instrument solely
securing the rights and preserving the Lien of the Trust Collateral Agent, for the benefit of the Noteholders. 
 SECTION
4.7.      Purchase of Receivables Upon Breach of Covenant. Upon discovery by any of the Servicer, a Responsible Officer of the Trust Collateral Agent, the Owner Trustee or a Responsible Officer of the Trustee of
a breach of any of the covenants set forth in Sections 3.4, 3.5, 3.6, 4.5(a) or 4.6 that materially and adversely affects the interests of the Noteholders in any Receivable (including any Liquidated Receivable), the party discovering such breach
shall give prompt written notice to the others; provided, however, that the failure to give any such notice shall not affect any obligation of GM Financial as Servicer under this Section. As of the second


  
 37 












 
Accounting Date following its discovery or receipt of notice of any breach of any covenant set forth in Sections 3.4, 3.5, 3.6, 4.5(a) or 4.6 which materially and adversely affects the interests
of the Noteholders in any Receivable (including any Liquidated Receivable) (or, at GM Financial’s election, the first Accounting Date so following) or the related Financed Vehicle, GM Financial shall, unless such breach shall have been cured in
all material respects, purchase from the Trust the Receivable affected by such breach and, on the related Determination Date, GM Financial shall pay the related Purchase Amount. It is understood and agreed that the obligation of GM Financial to
purchase any Receivable (including any Liquidated Receivable) with respect to which such a breach has occurred and is continuing shall, if such obligation is fulfilled, constitute the sole remedy against GM Financial for such breach available to the
Noteholders, the Issuer, the Owner Trustee or the Trust Collateral Agent; provided, however, that GM Financial shall indemnify the Trust, the Owner Trustee, the Trust Collateral Agent, the Trustee and the Noteholders from and against all
costs, expenses, losses, damages, claims and liabilities, including reasonable fees and expenses of counsel, which may be asserted against or incurred by any of them as a result of third-party claims arising out of the events or facts giving rise to
such breach. 
 SECTION 4.8.      Total Servicing Fee; Payment of Certain Expenses by
Servicer. On each Distribution Date, the Servicer shall be entitled to receive out of the Collection Account the Base Servicing Fee and any Supplemental Servicing Fee for the related Collection Period (together, the “Servicing
Fee”) pursuant to Section 5.7. The Servicer shall be required to pay all expenses incurred by it in connection with its activities under this Agreement (including taxes imposed on the Servicer, expenses incurred in connection with
distributions and reports made by the Servicer to the Noteholders and all other fees and expenses of the Owner Trustee, the Trust Collateral Agent or the Trustee; provided, however, the Servicer shall not be required to pay taxes levied or
assessed against the Trust or claims against the Trust in respect of indemnification unless such taxes and claims are expressly stated to be for the account of GM Financial). The Servicer shall be liable for the fees and expenses of the Owner
Trustee, the Trust Collateral Agent, the Trustee, the Custodian and the Independent Accountants. Notwithstanding the foregoing, if the Servicer shall not be GM Financial, a successor to GM Financial as Servicer permitted by Section 9.3 shall
not be liable for taxes levied or assessed against the Trust or claims against the Trust in respect of indemnification, or the fees and expenses referred to above. 

SECTION 4.9.      Servicer’s Certificate and Asset-Level Information. 

(a)    Servicer’s Certificate. No later than noon Eastern time on each Determination Date, the
Servicer shall deliver (electronic delivery being acceptable) to the Trustee, the Owner Trustee and the Trust Collateral Agent the monthly Servicer’s Certificate. The Servicer will also deliver the Servicer’s Certificate to each Rating
Agency on the same date the Servicer’s Certificate is publicly available (provided that if the Servicer’s Certificate is not made publicly available, the Servicer will deliver it to each Rating Agency no later than the twenty-fifth (25th) of each month (or if not a Business Day, the next succeeding Business Day)). Each Servicer’s Certificate will be executed by a Responsible Officer of the Servicer and contain among other things:
(i) all information necessary to enable the Trust Collateral Agent to make the distributions required by Sections 5.7(a) and 5.7(b), (ii) a listing of all Purchased Receivables and Sold Receivables purchased by the Servicer or sold by the
Issuer as of the related Accounting Date, identifying the Receivables so purchased by the Servicer or sold by the Issuer, (iii) all information necessary to enable the Trust Collateral Agent to make such statements available to Noteholders as
required by 

  
 38 












 
Section 5.9 and (iv) solely in the case of the first monthly Servicer’s Certificate, the disclosure required by Rule 4(c)(1)(ii) of Regulation RR, 17 C.F.R. § 246.1, et seq.
(the “Credit Risk Retention Rules”). Receivables purchased by the Servicer or by the Seller on the related Accounting Date and each Receivable which became a Liquidated Receivable or which was paid in full during the related
Collection Period shall be identified by account number (as set forth in the Schedule of Receivables). 

(b)    Asset-Level Information. On or before the fifteenth (15th) day following each Distribution
Date, the Servicer will prepare a Form ABS-EE, including an asset data file and asset-related document containing the asset-level information for each Receivable for the prior Collection Period as required by
Item 1A of Form 10-D. 
 SECTION 4.10.      Annual
Statement as to Compliance, Notice of Servicer Termination Event. 
 (a)    To the extent

 SECTION 5.1.      Establishment of Trust
Accounts. 
 (a)    (i)     The Trust Collateral Agent, on behalf of the
Noteholders, shall establish and maintain in its own name an Eligible Deposit Account (the “Collection Account”), bearing a designation clearly indicating that the funds deposited therein are held for the benefit of the Trust
Collateral Agent on behalf of the Noteholders. The Collection Account shall initially be established with the Trust Collateral Agent. 

(ii)    The Trust Collateral Agent, on behalf of the Noteholders, shall establish and maintain in its own
name an Eligible Deposit Account (the “Note Distribution Account”), bearing a designation clearly indicating that the funds deposited therein are held for the benefit of the Trust Collateral Agent on behalf of the Noteholders. The
Note Distribution Account shall initially be established with the Trust Collateral Agent. 

(iii)    The Trust Collateral Agent, on behalf of the Noteholders, shall establish and maintain in its
own name an Eligible Deposit Account (the “Reserve Account”), bearing a designation clearly indicating that the funds deposited therein are held for the benefit of the Trust Collateral Agent on behalf of the Noteholders. The Reserve
Account shall initially be established with the Trust Collateral Agent. 
 (b)    Funds on deposit in
the Collection Account, the Reserve Account and the Note Distribution Account (collectively, the “Trust Accounts”) shall be invested by the Trust Collateral Agent (or any custodian with respect to funds on deposit in any such
account) in Eligible Investments selected in writing by the Servicer (pursuant to standing instructions or otherwise). Absent receipt of such written investment direction from the Servicer, funds on deposit in the Trust Accounts shall be held
uninvested. All such Eligible Investments shall be held by or on behalf of the Trust Collateral Agent for the benefit of the Noteholders. Other than as permitted by the Rating Agencies, funds on deposit in any Trust Account shall be invested in
Eligible Investments that will mature so that such funds will be available at the close of business on the Business Day immediately preceding the following Distribution Date. All Eligible Investments will be held to


  
 41 












 
maturity. Each institution at which the relevant Trust Account is maintained shall invest the funds therein as directed in writing by the Servicer in Eligible Investments. The Servicer
acknowledges that upon its written request and at no additional cost, it has the right to receive notification after the completion of each such investment or the Trust Collateral Agent’s receipt of a broker confirmation. The Servicer agrees
that such notifications will not be provided by the Trust Collateral Agent hereunder, and the Trust Collateral Agent shall make available, upon request and in lieu of notifications, periodic account statements that reflect such investment activity.
No statement need be made available if no activity has occurred in the relevant Trust Account during such period. 

(c)    All Investment Earnings of moneys deposited in each Trust Account shall be deposited (or caused to
be deposited) in the Collection Account on each Distribution Date by the Trust Collateral Agent and applied as Available Funds on such Distribution Date, and any loss resulting from such investments shall be charged to the related Trust Account. The
Servicer will not direct the Trust Collateral Agent to make any investment of any funds 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, in either
case without any further action by any Person, and, in connection with any direction to the Trust Collateral Agent to make any such investment, if requested by the Trust Collateral Agent, the Servicer shall deliver to the Trust Collateral Agent an
Opinion of Counsel, acceptable to the Trust Collateral Agent, to such effect. 
 (d)     The Trust
Collateral Agent 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 Eligible Investment included therein except for losses attributable to the Trust Collateral Agent’s
negligence or bad faith or its failure to make payments on such Eligible Investments issued by the Trust Collateral Agent, in its commercial capacity as principal obligor and not as Trust Collateral Agent or as Trustee, in accordance with their
terms. 
 (e)     If (i) the Servicer shall have failed to give investment directions in
writing for any funds on deposit in the Trust Accounts to the Trust Collateral Agent by 1:00 p.m. Eastern Time (or such other time as may be agreed by the Issuer and the Trust Collateral Agent) on any Business Day; or (ii) a Default or Event of
Default shall have occurred and is continuing with respect to the Notes but the Notes shall not have been declared due and payable, or, if such Notes shall have been declared due and payable following an Event of Default, amounts collected or
received from the Trust Property are being applied as if there had not been such a declaration; then the Trust Collateral Agent shall, to the fullest extent practicable, invest and reinvest funds in the Trust Accounts in accordance with the
instructions outlined in the most recent investment direction letter between the Servicer and the Trust Collateral Agent. 

(f)     (i)     The Trust Collateral Agent shall possess all right, title and
interest in all funds on deposit from time to time in the Trust Accounts and in all proceeds thereof for the benefit of the Noteholders and all such funds, investments, proceeds and income shall be part of the Owner Trust Estate. Except as otherwise
provided herein, the Trust Accounts shall be under the sole dominion and control of the Trust Collateral Agent for the benefit of the Noteholders. If, at any time, any of the Trust Accounts ceases to be an Eligible Deposit Account, the Trust
Collateral Agent (or the Servicer on its behalf) shall within five (5) Business Days (or such longer period as to which each Rating Agency may consent) establish a new Trust Account as an Eligible Deposit


  
 42 












 
Account and shall transfer any cash and/or any investments to such new Trust Account. In connection with the foregoing, the Servicer agrees that, in the event that any of the Trust Accounts are
not accounts with the Trust Collateral Agent, the Servicer shall notify the Trust Collateral Agent in writing promptly upon any of such Trust Accounts ceasing to be an Eligible Deposit Account. 

(ii)    With respect to the Trust Account Property, the Trust Collateral Agent agrees that: 

(A)    any Trust Account Property that is held in deposit accounts shall be held solely
in the Eligible Deposit Accounts; and, except as otherwise provided herein, each such Eligible Deposit Account shall be subject to the exclusive custody and control of the Trust Collateral Agent, and the Trust Collateral Agent shall have sole
signature authority with respect thereto; 
 (B)    any Trust Account Property that
constitutes Physical Property shall be delivered to the Trust Collateral Agent in accordance with paragraph (a) of the definition of “Delivery” and shall be held, pending maturity or disposition, solely by the Trust Collateral Agent
or a securities intermediary (as such term is defined in Section 8-102(14) of the UCC) acting solely for the Trust Collateral Agent; 

(C)    the “securities intermediary’s jurisdiction” for purposes of
Section 8-110 of the UCC shall be the State of New York; 

(D)    any Trust Account Property that is a book-entry security held through the Federal
Reserve System pursuant to federal book-entry regulations shall be delivered in accordance with paragraph (b) of the definition of “Delivery” and shall be maintained by the Trust Collateral Agent, pending maturity or disposition,
through continued book-entry registration of such Trust Account Property as described in such paragraph; 

(E)    any Trust Account Property that is an “uncertificated security”
or a “security entitlement” under Article 8 of the UCC and that is not governed by clause (D) above shall be delivered to the Trust Collateral Agent in accordance with paragraph (c) or (d), if applicable, of the definition
of “Delivery” and shall be maintained by the Trust Collateral Agent, pending maturity or disposition, through continued registration of the Trust Collateral Agent’s (or its nominee’s) ownership of such security; and 

(F)    any cash that is Trust Account Property shall be considered a “financial
asset” under Article 8 of the UCC. 
 (g)    The Servicer shall have the power to instruct the
Trust Collateral Agent to make withdrawals and payments from the Trust Accounts for the purpose of permitting the Servicer and the Trust Collateral Agent to carry out their respective duties hereunder.

have resulted from mistaken deposits or postings or checks returned for insufficient funds. The amount to be reimbursed hereunder shall be paid to the Servicer on the related Distribution Date pursuant to Section 5.7(a)(i) upon certification by
the Servicer of such amounts and the provision of such information to the Trust Collateral Agent. The Servicer will additionally be entitled to receive from amounts on deposit in the Collection Account with respect to a Collection Period any amounts

in accordance with the Trust Agreement, the aggregate amount remaining in the Collection Account. 
 On any
Distribution Date with respect to which no Servicer’s Certificate was delivered, to the extent there are Available Funds in the Collection Account, the Trust Collateral Agent will make payments of the Noteholders’ Interest Distributable
Amounts described in (iii), (v), (vii) and (ix) above.

 46 












 
of the Indenture or (C) the receipt of Insolvency Proceeds pursuant to Section 10.1(b), the Total Available Funds and amounts deposited in the Note Distribution Account (including any
such Insolvency Proceeds) shall be paid to the Noteholders pursuant to Section 5.6(a) of the Indenture. 

(c)     In the event that the Collection Account is maintained with an institution other than the
Trust Collateral Agent, the Servicer shall instruct and cause such institution to make all deposits and distributions pursuant to Sections 5.7(a) and 5.7(b) on the related Distribution Date. 

(d)    In the event that any withholding tax is imposed on the Trust’s payment (or allocations of
income) to a Noteholder, such tax shall reduce the amount otherwise distributable to the Noteholder in accordance with this Section 5.7. The Trust Collateral Agent is hereby authorized and directed to retain from amounts otherwise distributable
to the Noteholders sufficient funds for the payment of any tax attributable to the Trust (but such authorization shall not prevent the Trust Collateral Agent from contesting any such tax in appropriate proceedings, and withholding payment of such
tax, if permitted by law, pending the outcome of such proceedings). The amount of any withholding tax imposed with respect to a Noteholder shall be treated as cash distributed to such Noteholder at the time it is withheld by the Trust and remitted
to the appropriate taxing authority. If there is a possibility that withholding tax is payable with respect to a distribution (such as a distribution to a non-U.S. Noteholder), the Trust Collateral Agent may
in its sole discretion withhold such amounts in accordance with this clause (d). In the event that a Noteholder wishes to apply for a refund of any such withholding tax, the Trust Collateral Agent shall reasonably cooperate with such Noteholder in
making such claim so long as such Noteholder agrees to reimburse the Trust Collateral Agent for any out-of-pocket expenses (including legal fees and expenses) incurred.

 (e)     Distributions required to be made to Noteholders on any Distribution Date shall be made
to each Noteholder of record on the preceding Record Date either by (i) wire transfer, in immediately available funds, to the account of such Holder at a bank or other entity having appropriate facilities therefore, if such Noteholder shall
have provided to the Note Registrar appropriate written instructions at least five (5) Business Days prior to such Distribution Date and such Holder’s Notes in the aggregate evidence a denomination of not less than $1,000,000 or
(ii) by check mailed to such Noteholder at the address of such holder appearing in the Note Register. Notwithstanding the foregoing, the final distribution in respect of any Note (whether on the Final Scheduled Distribution Date or otherwise)
will be payable only upon presentation and surrender of such Note at the office or agency maintained for that purpose by the Note Registrar pursuant to Section 2.4 of the Indenture. 

(f)     Subject to Section 5.1 and this Section, monies received by the Trust Collateral Agent
hereunder need not be segregated in any manner except to the extent required by law and may be deposited under such general conditions as may be prescribed by law, and the Trust Collateral Agent shall not be liable for any interest thereon. 

SECTION 5.8.    Reserve Account. 

(a)     On the Closing Date, the Seller shall deposit the Specified Reserve Balance into the Reserve
Account. Amounts held from time to time in the Reserve Account shall be held by the Trust Collateral Agent for the benefit of the Noteholders. 

  
 47 












 (b)    The Seller may, from time to time after the date
hereof, request each Rating Agency to approve a formula for determining the Specified Reserve Balance that is different from the formula set forth herein, which may result in a decrease in the amount of the Specified Reserve Balance or change the
manner by which the Reserve Account is funded. Notwithstanding any other provision of this Agreement, the use of such new formula will be deemed to be approved upon the satisfaction of the Rating Agency Condition with respect to the use of such new
formula, and the Specified Reserve Balance will be determined in accordance with such new formula and this Agreement will be amended to reflect such new formula without the consent of any Noteholder. 

(c)    On each Distribution Date, the Servicer shall instruct the Trust Collateral Agent (based on the
information contained in the Servicer’s Certificate delivered on the related Determination Date) (A) if the amount on deposit in the Reserve Account (without taking into account any amount on deposit in the Reserve Account representing net
Investment Earnings) is less than the Specified Reserve Balance, in which case the Trust Collateral Agent shall, after payment of any amounts required to be distributed pursuant to clauses (i) through (x) of Section 5.7(a) deposit in the
Reserve Account the Reserve Account Deposit Amount pursuant to Section 5.7(a)(xi), and (B) if the amount on deposit in the Reserve Account, after giving effect to all other deposits thereto and withdrawals therefrom to be made on such
Distribution Date is greater than the Specified Reserve Balance, in which case the Trust Collateral Agent shall distribute the amount of such excess as part of Available Funds on such Distribution Date. 

(d)    On each Distribution Date, the Servicer shall instruct the Trust Collateral Agent (based on the
information contained in the Servicer’s Certificate delivered on the related Determination Date) to withdraw the Reserve Account Withdrawal Amount from the Reserve Account and deposit such amounts in the Collection Account to be included as
Total Available Funds for that Distribution Date. 
 (e)    Amounts properly transferred to the
Certificate Distribution Account for payment to the Certificateholder pursuant to this Agreement shall not be available to the Trust Collateral Agent or the Trust for the purpose of making deposits to the Reserve Account, or making payments to the
Noteholders, nor shall the Certificateholder be required to refund any amount properly received by them. 
 SECTION
5.9.    Statements to Noteholders. 
 (a)    On or prior to each Distribution
Date, the Trust Collateral Agent shall make available to each Noteholder of record a statement setting forth at least the following information as to the Notes solely to the extent such information has been received from the Servicer pursuant to
Section 4.9:

(vi)    the amount of the Servicing Fee paid to the Servicer with respect to the related Collection Period
and/or due but unpaid with respect to such Collection Period or prior Collection Periods, as the case may be; 

(vii)    the Noteholders’ Interest Carryover Amount, if any, and the change in that amount from the
preceding statement; 
 (viii)    the Yield Supplement Overcollateralization Amount as of the opening of
business on the first day of the preceding Collection Period and as of the close of business on the last day of the preceding Collection Period; 

(ix)    the amount of the aggregate Realized Losses, if any, for the second preceding Collection Period;
and 
 (x)    the aggregate Purchase Amounts for Receivables, if any, that were repurchased by the
Servicer or the Seller in such period. 
 (b)    The Trust Collateral Agent will make available each
month to each Noteholder the statements referred to in Section 5.9(a) above (and certain other documents, reports and information regarding the Receivables provided by the Servicer from time to time) via the Trust Collateral Agent’s
internet website, with the use of a password provided by the Trust Collateral Agent. The Trust Collateral Agent’s internet website will be located at https://getinvestorreporting.bnymellon.com or at such other address as the Trust Collateral
Agent shall notify the Noteholders from time to time. For assistance with regard to this service, Noteholders can call the Trust Collateral Agent’s technical assistance center at (800) 332-4550. The Trust
Collateral Agent shall have the right to change the way the statements referred to in Section 5.9(a) above are distributed in order to make such distribution more convenient and/or more accessible to the parties entitled to receive such
statements so long as such statements are only provided to the then current Noteholders. The Trust Collateral Agent shall provide notification of any such change to all parties entitled to receive such statements in the manner described in
Section 12.3 hereof, Section 11.4 of the Indenture or Section 11.5 of the Indenture, as appropriate.

any such Person against any liability that would otherwise be imposed by reason of a breach of this Agreement or willful misfeasance, bad faith or negligence (excluding errors in judgment) in the performance of duties; provided,
further, that this provision shall not affect any liability to indemnify the Trust Collateral Agent, the Trustee and the Owner Trustee for costs, taxes, expenses, claims, liabilities, losses or damages paid by the Trust Collateral Agent, the

The Servicer also may at any time perform specific 

  
 58 












 
duties through sub-contractors in accordance with the Servicing Policies and Procedures. No delegation or
sub-contracting by the Servicer of its duties herein in the manner described in this Section 8.5 shall relieve the Servicer of its responsibility with respect to such duties. 

SECTION 8.6.     Servicer Not to Resign. Subject to the provisions of Section 8.3,
the Servicer shall not resign from the obligations and duties imposed on it by this Agreement as Servicer except upon a determination that, by reason of a change in legal requirements, the performance of its duties under this Agreement would cause
it to be in violation of such legal requirements in a manner which would have a material adverse effect on the Servicer if the Majority Noteholders do not elect to waive the obligations of the Servicer to perform the duties which render it legally
unable to act or to delegate those duties to another Person. Any such determination permitting the resignation of the Servicer shall be evidenced by an Opinion of Counsel to such effect delivered and acceptable to the Trust Collateral Agent and the
Owner Trustee. No resignation of the Servicer shall become effective until an entity acceptable to the Majority Noteholders shall have assumed the responsibilities and obligations of the Servicer.

 (a)     Any failure
by the Servicer to deliver to the Trust Collateral Agent for distribution to Noteholders any proceeds or payment required to be so delivered under the terms of this Agreement that continues unremedied for a period of five (5) Business Days
after written notice is received by the Servicer from the Trust Collateral Agent (at the direction of the Majority Noteholders) or after actual knowledge of such failure by a Responsible Officer of the Servicer; 

(b)     Failure on the part of the Servicer duly to observe or perform any other covenants or
agreements of the Servicer set forth in this Agreement, which failure (i) materially and adversely affects the rights of Noteholders, and (ii) continues unremedied for a period of sixty (60) days after actual knowledge thereof by a

 (c)     An Insolvency Event with respect to the Servicer; 

provided, however, that if (i) any delay or failure of performance referred to in Section 9.1(a) above shall
have been caused by force majeure or other similar occurrences, the five (5) Business Day grace period shall be extended for an additional sixty (60) calendar days and (ii) if any delay or failure of performance referred to in
Section 9.1(b) above shall have been caused by force majeure or other similar occurrences, the sixty (60) day grace period shall be extended for an additional ninety (90) calendar days. 

SECTION 9.2.     Consequences of a Servicer Termination Event. If a Servicer
Termination Event shall occur and be continuing, the Trust Collateral Agent may, or at the direction of the Majority Noteholders shall, by notice given in writing to the Servicer (and to the

Trust Collateral Agent if given by the Noteholders) terminate all of the rights and obligations of the Servicer under this Agreement. On or after the receipt by the Servicer of such written
notice or upon termination of the term of the Servicer, all authority, power, obligations and responsibilities of the Servicer under this Agreement, whether with respect to the Notes, the Certificate or the Other Conveyed Property or otherwise,
shall pass to, be vested in and become obligations and responsibilities of the successor Servicer appointed by the Majority Noteholders; provided, however, that the successor Servicer shall have no liability with respect to any obligation
which was required to be performed by the terminated Servicer prior to the date that the successor Servicer becomes the Servicer or any claim of a third party based on any alleged action or inaction of the terminated Servicer. The successor Servicer
is authorized and empowered by this Agreement to execute and deliver, on behalf of the terminated Servicer, as attorney-in-fact or otherwise, any and all documents and
other instruments and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement of the Receivables and the Other Conveyed Property and
related documents to show the Trust as lienholder or secured party on the related Lien Certificates, or otherwise. The terminated Servicer agrees to cooperate with the successor Servicer in effecting the termination of the responsibilities and
rights of the terminated Servicer under this Agreement, including, without limitation, the transfer to the successor Servicer for administration by it of all cash amounts that shall at the time be held by the terminated Servicer for deposit, or have
been deposited by the terminated Servicer, in the Collection Account or thereafter received with respect to the Receivables and the delivery to the successor Servicer of all Receivable Files, Monthly Records and Collection Records and a computer
tape in readable form as of the most recent Business Day containing all information necessary to enable the successor Servicer to service the Receivables and the Other Conveyed Property. The terminated Servicer shall grant the Trust Collateral
Agent, the successor Servicer and the Majority Noteholders reasonable access to the terminated Servicer’s premises at the terminated Servicer’s expense. 

SECTION 9.3.     Appointment of Successor. 

(a)     On and after the time the Servicer receives a notice of termination pursuant to
Section 9.2 or upon the resignation of the Servicer pursuant to Section 8.6, the Controlling Party may, or at the written direction of the Majority Noteholders shall, appoint an eligible servicer as successor Servicer or may petition a
court of competent jurisdiction to appoint a Person that it determines is competent to perform the duties of the Servicer hereunder as successor Servicer. Pending appointment pursuant to the preceding sentence, the outgoing Servicer shall continue
to act as Servicer until a successor has been appointed and accepted such appointment. Any successor Servicer shall be the successor in all respects to the Servicer in its capacity as Servicer under this Agreement and the transactions set forth or
provided for in this Agreement, and shall be subject to all the rights, responsibilities, restrictions, duties, liabilities and termination provisions relating thereto placed on the Servicer by the terms and provisions of this Agreement except as
otherwise stated herein. The Trust Collateral Agent and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. If a successor Servicer is acting as Servicer hereunder, it shall
be subject to termination under Section 9.2 upon the occurrence of any Servicer Termination Event applicable to it as Servicer. If no Person has accepted its appointment as successor Servicer when the predecessor Servicer ceases to act as
Servicer in accordance with Section 9.2 or Section 8.6, the Trust Collateral Agent or other eligible successor servicer appointed by the Trust Collateral Agent and who has accepted such appointment, will,


  
 60 












 
without further action, be automatically appointed the successor Servicer. Notwithstanding the above, if the Trust Collateral Agent is unwilling or legally unable to act as successor Servicer, it
may appoint, or petition a court of competent jurisdiction to appoint, an institution whose business includes the servicing of motor vehicle receivables, as successor Servicer. All reasonable costs and expenses incurred in connection with
transferring the servicing of the Receivables to the successor Servicer and amending this agreement to reflect such succession as Servicer pursuant to this Section shall be paid by the predecessor Servicer upon presentation of reasonable
documentation of such costs and expenses. The Trust Collateral Agent will be released from its duties and obligations as successor Servicer on the date that a new servicer agrees to appointment as successor Servicer hereunder. 

(b)     Any successor Servicer shall be entitled to such compensation (whether payable out of the
Collection Account or otherwise) as the Servicer would have been entitled to under this Agreement if the Servicer had not resigned or been terminated hereunder or such additional compensation as the Majority Noteholders and such successor Servicer
may agree on. 
 SECTION 9.4.     Notification to Noteholders. Upon any termination
of, or appointment of a successor to, the Servicer, the Trust Collateral Agent shall give prompt written notice thereof to each Noteholder and to the Seller (who shall promptly deliver such notice to the Rating Agencies). 

SECTION 9.5.     Waiver of Past Defaults. The Majority Noteholders may, on behalf of all
Noteholders, waive any default by the Servicer in the performance of its obligations hereunder and its consequences. Upon any such waiver of a past default, such default shall cease to exist, and any Servicer Termination Event arising therefrom
shall be deemed to have been remedied for every purpose of this Agreement and the Basic Documents. No such waiver shall extend to any subsequent or other default or impair any right consequent thereto.

amount to be paid for such purchase (as set forth in the following sentence) shall be sufficient to pay the full amount of principal, and interest then due and payable on the Notes. To exercise such option, the Servicer or the Seller, as the case
may be, shall deposit pursuant to Section 5.6 in the Collection Account an amount equal to the greater of (i) the amount necessary to pay the full amount of principal and interest then due and payable on the Notes and (ii) the
aggregate Purchase Amount for the Receivables (including Liquidated Receivables), plus the appraised value of any other property held by the Trust, (such value to be determined by the Servicer, or if the Trust Collateral Agent has received
written notice that there is a material error in the Servicer’s calculation, by an appraiser mutually agreed upon by the Servicer and the Trust Collateral Agent), and shall succeed to all interests in and to the Trust.

 (b)     Upon any sale of the assets of the Trust
pursuant to Section 8.1 of the Trust Agreement, the Servicer shall instruct the Trust Collateral Agent to deposit the proceeds from such sale after all payments and reserves therefrom (including the expenses of such sale) have been made (the
“Insolvency Proceeds”) in the Collection Account. 
 (c)     Notice of any
termination of the Trust shall be given by the Servicer to the Owner Trustee, the Trustee, the Trust Collateral Agent and the Rating Agencies as soon as practicable after the Servicer has received notice thereof. 

(d)     Following the satisfaction and discharge of the Indenture and the payment in full of the
principal of and interest on the Notes, the Certificateholder will succeed to the rights of the Noteholders hereunder and the Certificateholder will succeed to the rights of, and assume the obligations of, the Trust Collateral Agent pursuant to this
Agreement.

information regarding Obligors, then the Servicer 

  
 64 












 
may condition its delivery of that portion of the Review Report to the requesting Noteholder on such Noteholder’s delivery to the Servicer of an agreement acknowledging that such Noteholder
may use such information only for the limited purpose of assessing the nature of the related breaches of representations and warranties and may not use that information for any other purpose.

changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Noteholders; provided, however, that such amendments require: (i) satisfaction of the Rating Agency Condition

 (b)     This Agreement may also be amended from time to time by the parties hereto, with the
consent of the Trustee, and with the consent of the Majority Noteholders for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the

It shall not be necessary for the consent of the Noteholders pursuant to this Section to approve the particular form of any
proposed amendment or consent, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents (and any other consents of Noteholders provided for in this Agreement) and of evidencing the

with respect to) each Receivable and the amounts from time to time deposited in the Collection Account in respect of such Receivable. 

(e)    The Servicer shall maintain its computer systems so that, from and after the time of sale under
this Agreement of the Receivables to the Issuer, the Servicer’s master computer records (including any backup archives) that refer to a Receivable shall indicate clearly the interest of the Trust in such Receivable and that such Receivable is
owned by the Trust. Indication of the Trust’s interest in a Receivable shall be deleted from or modified on the Servicer’s computer systems when, 

  
 66 












 
and only when, the related Receivable shall have been paid in full or repurchased or sold pursuant to this Agreement. 

(f)    If at any time the Seller or the Servicer shall propose to sell, grant a security interest in or
otherwise transfer any interest in automotive receivables to any prospective purchaser, lender or other transferee, the Servicer shall give to such prospective purchaser, lender or other transferee computer tapes, records or printouts (including any

adequate for realization against the collateral security, and (D) has not been amended or collections with respect to which waived, other than as evidenced in the Receivable File or the Servicer’s electronic records relating thereto. 

2.        Compliance with Law. All requirements of applicable federal, State
and local laws, and regulations thereunder (including, without limitation, usury laws, the federal Truth-in-Lending Act, the Equal Credit Opportunity Act, the Fair
Credit Reporting Act, the Fair Debt Collection Practices Act, the Federal Trade Commission Act, the Magnuson-Moss Warranty Act, the Federal Reserve Board’s Regulations “B” and “Z” (including amendments to the Federal

Motor Vehicle Retail Installment Sales Act, the Gramm-Leach-Bliley Act and State adaptations of the National Consumer Act and of the Uniform Consumer Credit Code and other consumer credit laws and equal credit opportunity and disclosure laws) in
respect of the Receivables and the Financed Vehicles, have been complied with in all material respects. 

3.        Binding Obligation. Each Receivable represents the genuine, legal,
valid and binding payment obligation of the Obligor thereon, enforceable by the holder thereof in accordance with its terms, except (A) as enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the
enforcement of creditors’ rights generally and by equitable limitations on the availability of specific remedies, regardless of whether such enforceability is considered in a proceeding in equity or at law and (B) as such Receivable may be
modified by the application after the Cutoff Date of the Servicemembers Civil Relief Act, as amended; and, to the best of the Seller’s and the Servicer’s knowledge, all parties to each Receivable had full legal capacity to execute and
deliver such Receivable and all other documents related thereto and to grant the security interest purported to be granted thereby. 

4.        Schedule of Receivables. The information set forth in the Schedule of
Receivables has been produced from the Electronic Ledger and was true and correct in all material respects as of the close of business on the Cutoff Date. 

  
 SCH-B-1-1 












 5.        Marking Records.
Each of GM Financial and the Seller agree that the Receivables have been sold to the Trust pursuant to the Sale and Servicing Agreement and Granted to the Trust Collateral Agent pursuant to the Indenture. Further, GM Financial has indicated in its
computer files that the Receivables are owned by the Trust. 
 6.        Chattel
Paper. The Receivables constitute “tangible chattel paper” or “electronic chattel paper” within the meaning of the UCC. 

7.        One Original. There is only one original executed copy (or with
respect to “electronic chattel paper”, one authoritative copy) of each Contract. With respect to Contracts that are “electronic chattel paper”, each authoritative copy (a) is unique, identifiable and unalterable (other than
with the participation of the Trust Collateral Agent in the case of an addition or amendment of an identified assignee and other than a revision that is readily identifiable as an authorized or unauthorized revision), (b) has been marked with a
legend to the following effect: “Authoritative Copy” and (c) has been communicated to and is maintained by or on behalf of the Custodian. 

8.        Not an Authoritative Copy. With respect to Contracts that are
“electronic chattel paper”, the Servicer has marked all copies of each such Contract other than an authoritative copy with a legend to the following effect: “This is not an authoritative copy.”  

9.        Revisions. With respect to Contracts that are “electronic
chattel paper”, the related Receivables have been established in a manner such that (a) all copies or revisions that add or change an identified assignee of the authoritative copy of each such Contract must be made with the participation
of the Trust Collateral Agent and (b) all revisions of the authoritative copy of each such Contract are readily identifiable as an authorized or unauthorized revision. 

10.        Pledge or Assignment. With respect to Contracts that are
“electronic chattel paper”, the authoritative copy of each Contract communicated to the Custodian has no marks or notations indicating that it has been pledged, assigned or otherwise conveyed to any Person other than the Trust Collateral
Agent. 
 11.        Receivable Files Complete. There exists a Receivable
File pertaining to each Receivable. Related documentation concerning the Receivable, including any documentation regarding modifications of the Contract, will be maintained electronically by the Servicer in accordance with customary policies and
procedures. With respect to any Receivables that are “tangible chattel paper”, the complete Receivable File for each Receivable currently is in the possession of the Custodian. 

12.        Receivables in Force. No Receivable has been satisfied, or, to the
best of the Seller’s and the Servicer’s knowledge, subordinated or rescinded, and the Financed Vehicle securing each such Receivable has not been released from the lien of the related Receivable in whole or in part. No terms of any
Receivable have been waived, altered or modified in any respect since its origination, except by instruments or documents identified in the Receivable File or the Servicer’s electronic records. 

13.        Good Title. Immediately prior to the conveyance of the Receivables
to the Trust pursuant to this Agreement, the Seller was the sole owner thereof and had good and indefeasible 

  
 SCH-B-1-2 












 
title thereto, free of any Lien and, upon execution and delivery of this Agreement by the Seller, the Trust shall have good and indefeasible title to and will be the sole owner of such
Receivables, free of any Lien. The Seller has not taken any action to convey any right to any Person that would result in such Person having a right to payments received under the related Insurance Policies or the related Dealer Agreements or Dealer
Assignments or to payments due under such Receivables. No Dealer has a participation in, or other right to receive, proceeds of any Receivable. 

14.        Security Interest in Financed Vehicle. Each Receivable created or
shall create a valid, binding and enforceable first priority security interest in favor of GM Financial in the Financed Vehicle. The Lien Certificate for each Financed Vehicle shows, or GM Financial has commenced procedures that will result in such
Lien Certificate which will show, GM Financial named (which may be accomplished by the use of a properly registered DBA name in the applicable jurisdiction) as the original secured party under each Receivable as the holder of a first priority
security interest in such Financed Vehicle. Immediately after the sale, transfer and assignment by the Seller to the Trust, each Receivable will be secured by an enforceable and perfected first priority security interest in the Financed Vehicle,
which security interest is prior to all other Liens upon and security interests in such Financed Vehicle which now exist or may hereafter arise or be created (except, as to priority, for any lien for taxes, labor or materials affecting a Financed
Vehicle). To the best of the Seller’s and the Servicer’s knowledge, as of the Cutoff Date, there were no Liens or claims for taxes, work, labor or materials affecting a Financed Vehicle which are or may be Liens prior or equal to the Liens
of the related Receivable. 
 15.        Receivable Not Assumable. No
Receivable is assumable by another Person in a manner which would release the Obligor thereof from such Obligor’s obligations to the owner thereof with respect to such Receivable. 

16.        No Defenses. No Receivable is subject to any right of rescission,
setoff, counterclaim or defense, including the defense of usury, and the operation of any of the terms of any Receivable, or the exercise of any right thereunder, will not render such Receivable unenforceable in whole or in part and no such right
has been asserted or threatened with respect to any Receivable. 
 17.        No
Default. There has been no default, breach, or, to the knowledge of the Seller and Servicer, violation or event permitting acceleration under the terms of any Receivable (other than payment delinquencies of not more than thirty (30) days),
and, to the best of the Seller’s and the Servicer’s knowledge, no condition exists or event has occurred and is continuing that with notice, the lapse of time or both would constitute a default, breach, violation or event permitting
acceleration under the terms of any Receivable, and there has been no waiver of any of the foregoing. 

18.        Insurance. At the time of an origination of a Receivable by GM
Financial or a Dealer, each Financed Vehicle is required to be covered by a comprehensive and collision insurance policy, and each Receivable permits the holder thereof to obtain physical loss and damage insurance at the expense of the Obligor if
the Obligor fails to do so. 
 19.        Fixed Payments, Simple Interest.
Each Receivable provides for fixed level monthly payments (provided that the first and last payments may be minimally different from the level 

  
 SCH-B-1-3 












 
payment amount) that fully amortize the Amount Financed over the original term, and amortizes using the Simple Interest Method. 

20.        Certain Characteristics of the Receivables. 

(A) Each Receivable had a remaining maturity, as of the Cutoff Date, of not less than three (3) months
and not more than eighty-four (84) months. 
 (B) Each Receivable had an original maturity, as of the
Cutoff Date, of not less than three (3) months and not more than eighty-four (84) months.

(D) Each Receivable had an Annual Percentage Rate, as of the Cutoff Date, of not more than 20%. 

(E) No Receivable was more than thirty (30) days past due as of the Cutoff Date.

thereof. 
 (G) Each Obligor had a billing address in the United States or in a United States territory as
of the date of origination of the related Receivable. 
 (H) Each Receivable is denominated in, and each
Contract provides for payment in, United States dollars. 
 (I) Each Receivable arose under a Contract that
is assignable without the consent of, or notice to, the Obligor thereunder, and does not contain a confidentiality provision that purports to restrict the ability of the Servicer to exercise its rights under the Sale and Servicing Agreement,
including, without limitation, its right to review the Contract. Each Receivable prohibits the sale or transfer of the Financed Vehicle without the consent of the Servicer. 

(J) Each Receivable arose under a Contract with respect to which GM Financial has performed all obligations
required to be performed by it thereunder. 
 (K) No automobile related to a Receivable was held in
repossession inventory as of the Cutoff Date.

Obligor was in bankruptcy as of the Cutoff Date.

required to be made by any Person and actions required to be taken or performed by any Person in any jurisdiction to give the Trust and the Trust Collateral Agent a first priority perfected lien on, or ownership interest in, the Receivables and the
