shall hold the AART Owner Trust Estate (in the name of the Trust and not in the AART Owner Trustee’s name for the Trust, except as required by, and in accordance with, Section 2.8) in trust upon and subject to the conditions set
forth herein for the use and benefit of the Certificateholders, subject to the obligations of the Trust under the AART Transaction Documents. It is the intention of the parties hereto that the Trust constitute a statutory trust under the Statutory

transferred to and vested in the AART Owner Trustee, a co-trustee and/or a separate trustee, as the case may be. Any such trustee shall take such part of the AART Owner Trust Estate subject to the security interest of the AART Indenture Trustee
therein established under the AART Indenture. Such trustee’s acceptance of its appointment shall constitute acknowledgment of such security interest and shall constitute a Grant to the AART Indenture Trustee of a security interest in all

 Section 2.10 Representations and Warranties of the Depositor. The Depositor hereby
represents and warrants to the AART Owner Trustee that: 
 (a) The Depositor has been duly formed and is validly existing as an entity in
good standing under the laws of the State of Delaware, with power and authority to own its properties and to conduct its business as such properties are presently owned and such business is presently conducted and had at all relevant times, and now
has, power, authority and legal right to acquire, own and transfer the Secured Notes contemplated to be transferred to the Trust pursuant to the Trust Sale Agreement. 

(b) The Depositor is duly qualified to do business as a foreign entity in good standing, and has obtained all necessary licenses and
approvals, in all jurisdictions in which the ownership or lease of property or the conduct of its business requires such qualifications. 

(c) The Depositor has the power and authority to execute and deliver this Agreement and any other AART Transaction Documents to which the
Depositor is a party, and to carry out their respective terms, the Depositor has full power and authority to sell and assign the property to be sold and assigned to and deposited with the Trust as part of the AART Owner Trust Estate and the
Depositor has duly authorized such sale and assignment to the Trust by all necessary limited liability company action; and the execution, delivery and performance of this Agreement and any other AART Transaction Documents to which the Depositor is a
party have been duly authorized by the Depositor by all necessary limited liability company action. 
 (d) The consummation of the
transactions contemplated by this Agreement and any other AART Transaction Documents to which the Depositor is a party, and the fulfillment of the terms of this Agreement and any other AART Transaction Documents to which the Depositor is a party, do
not conflict with, result in any breach of any of the terms and provisions of or constitute (with or without notice or lapse of time) a default under, the certificate of formation or limited liability company agreement (or similar organizational
documents) of the Depositor, or any indenture, agreement or other instrument to which the Depositor is a party or by which it is bound, or result in the creation or imposition of any Lien upon any of its properties pursuant to the terms of any such
indenture, agreement or other instrument (other than pursuant to the AART Transaction Documents), or violate any law or, to the best of the Depositor’s knowledge, any order, rule or regulation applicable to the Depositor of any court or of any
federal or State regulatory body, administrative agency or other governmental instrumentality having jurisdiction over the Depositor or any of its properties. 

Section 2.11 Tax Treatment. As long as the Depositor or an Affiliate that is treated as the same Person as the Depositor for
federal income tax purposes is the sole owner of the Certificates, the Depositor and the AART Owner Trustee, by entering into this Agreement, express their intention that the Trust shall be disregarded for federal income tax purposes and shall be
treated as a division of the Depositor (or, if the Depositor is disregarded as a separate entity for federal income tax purposes, the Depositor’s first direct or indirect parent entity that is not disregarded as a separate entity for federal
income tax purposes). If the Depositor is not the sole owner of the Certificates, through sale of the Certificates, issuance by the Trust of additional Certificates to a Person other than the Depositor or otherwise, the Depositor and the AART Owner
Trustee, by entering into this Agreement, and the Certificateholders, by acquiring any Certificates or interest therein, (i) express their intention that the Certificates shall qualify as equity interests in either (A) a division of an
entity that is not disregarded as a separate entity for federal income tax purposes, or (B) a partnership for federal income tax purposes if the 

  
 4 








 
Certificates are owned by more than one Person (as long as (1) such Persons are not disregarded as separate entities for federal income tax purposes and (2) if such Persons are
disregarded as separate entities for federal income tax purposes, such Persons are not treated as a division of the same Person) and (ii) unless otherwise required by the appropriate taxing authorities, agree to treat the Certificates as equity
interests in an entity as described in clause (i) of this Section 2.11 for the purposes of federal income taxes, State and local income and franchise taxes, and any other taxes imposed upon, measured by, or based upon gross or net
income. The parties agree that, unless otherwise required by appropriate tax authorities, the Trust shall file or cause to be filed annual or other necessary returns, reports and other forms consistent with such characterization of the Trust for
such tax purposes. 
 Section 2.12 Merger and Consolidation of the Depositor. Any corporation, limited liability company or
other entity (i) into which the Depositor may be merged or with which it may be consolidated, (ii) resulting from any merger, or consolidation to which the Depositor shall be a party, (iii) succeeding to the business of the Depositor,
or (iv) 25% or more of the voting stock (or, if not a corporation, other voting interests) of which is owned directly or indirectly by Ally Financial or General Motors, which corporation or entity in any of the foregoing cases executes an
agreement of assumption to perform every obligation of the Depositor under this Agreement and the other AART Transaction Documents, shall be the successor to the Depositor under this Agreement without the execution or filing of any document or any
further act on the part of any of the parties to this Agreement. 
 ARTICLE III 

THE AART CERTIFICATES 

Section 3.1 Initial Beneficial Ownership. Since the formation of the Trust by the contribution by the Depositor pursuant to
Section 2.5, the Depositor has been the sole beneficial owner of the Trust. 
 Section 3.2 Form of the Certificates.

 (a) The Certificates shall be substantially in the form of Exhibit A. The Certificates shall represent the entire beneficial
interest in the Trust. The Certificates shall be executed on behalf of the Trust by manual or facsimile signature of a Responsible Officer of the AART Owner Trustee. Certificates bearing the manual or facsimile signatures of individuals who were, at
the time when such signatures shall have been affixed, authorized to sign on behalf of the Trust, shall be duly issued, fully paid and non-assessable beneficial interests in the Trust, notwithstanding that such individuals or any of them shall have
ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such offices at the date of authentication and delivery of such Certificates. 

(b) The Certificates shall be typewritten, printed, lithographed or engraved or produced by any combination of these methods (with or without
steel engraved borders) all as determined by the Authorized Officer of the AART Owner Trustee executing such Certificates, as evidenced by their execution of such Certificates. On the Closing Date, all of the Certificates shall be issued to the
Depositor as fully registered Certificates. 

  
 5 








 (c) The Certificates shall be issued in fully-registered form. The terms of the Certificates set
forth in Exhibit A shall form part of this Agreement. 
 Section 3.3 Execution, Authentication and Delivery. Concurrently
with the sale of the Secured Notes to the Trust pursuant to the Trust Sale Agreement, the AART Owner Trustee shall cause a single Certificate representing the entire beneficial interest in the Trust to be executed on behalf of the Trust,
authenticated and delivered to or upon the written order of the Depositor, signed by its chairman of the board, its president or any vice president, without further limited liability company action by the Depositor. Such Certificate shall be issued
to and held by the Depositor, as the initial Certificateholder. No Certificate shall entitle its holder to any benefit under this Agreement, or shall be valid for any purpose, unless there shall appear on such Certificate a certificate of
authentication substantially in the form set forth in Exhibit A, executed by the AART Owner Trustee or Deutsche Bank Trust Company Americas, as the AART Owner Trustee’s authenticating agent, by manual signature. Such authentication shall
constitute conclusive evidence that such Certificate shall have been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication. 

Section 3.4 Registration of Certificates; Registration of Transfer and Exchange of Certificates. 

(a) The Certificate Registrar shall keep or cause to be kept, at the office or agency maintained pursuant to Section 3.8, a
Certificate Register in which, subject to such reasonable regulations as it may prescribe, the AART Owner Trustee shall provide for the registration of Certificates and of transfers and exchanges of Certificates as provided herein. Deutsche Bank
Trust Company Americas shall be the initial Certificate Registrar. Upon any resignation of a Certificate Registrar, the AART Owner Trustee shall promptly appoint a successor or, if it elects not to make such an appointment, assume the duties of
Certificate Registrar. 
 (b) The Certificateholder may at any time, without consent of the Noteholders, sell, transfer, convey or assign in
any manner its rights to and interests in the Certificates, but only if: (i) such action will not result in a reduction or withdrawal of the rating of any class of Notes, (ii) the Certificateholder provides to the AART Owner Trustee and
the AART Indenture Trustee an Opinion of Counsel that such action shall not cause the Trust to be treated as an association (or publicly traded partnership) taxable as a corporation for federal income tax purposes, (iii) such transferee or
assignee agrees to take positions for tax purposes consistent with the tax positions set forth in Section 2.11 of this Agreement agreed to be taken by the Certificateholder, (iv) the conditions set forth in
Section 3.4(g) and (h) have been satisfied, and (v) in connection with any transfer of less than all of the interests in the Certificates, the transferor and the transferee specify the respective interests in the
Certificates to be held by the transferor and transferee, which interests may be determined by a formula or on any other basis agreed by transferor and transferee. No Certificate (other than the Certificates issued and held by the Depositor) may be
subdivided upon transfer or exchange in a manner such that the resulting Certificate represents less than a 2.00% fractional undivided interest in the Trust or such other amount as the Depositor may determine in order to prevent the Trust from being
a “publicly traded partnership” under Section 7704 of the Code, but in no event less than a 1.00% fractional undivided interest in the Trust. In addition, no transfer of a Certificate shall be registered unless


  
 6 








 
the transferee shall have provided to the AART Owner Trustee and the Certificate Registrar an Opinion of Counsel that in connection with such transfer no registration of the Certificates is
required under the Securities Act or applicable State securities law or that such transfer is otherwise being made in accordance with all applicable federal and State securities laws. If agreed by transferor and transferee, different interests may
be used for distributions of proceeds and for purposes of voting the Certificates, and the transferor shall notify the AART Owner Trustee of any such agreement in connection with such transfer. 

(c) In the event that the Depositor is no longer the sole Certificateholder, the Administrator shall promptly prepare amendments (subject to
the provisions regarding amendments in the applicable AART Transaction Documents) to the AART Transaction Documents to the extent necessary to reflect the establishment of the Certificate Distribution Account and the making of distributions to the
Certificateholders and such other matters as shall be agreed between the Depositor and the AART Owner Trustee. The expense of the foregoing amendments shall be paid by the Administrator. 

(d) Upon surrender for registration of transfer of any Certificates at the office or agency maintained pursuant to Section 3.8,
the AART Owner Trustee shall execute on behalf of the Trust, authenticate and deliver (or shall cause Deutsche Bank Trust Company Americas, as its authenticating agent to authenticate and deliver), in the name of the designated transferee or
transferees, one or more new Certificates of a like aggregate percentage interest in the Trust dated the date of authentication by the AART Owner Trustee or any authenticating agent. 

(e) At the option of a Holder, Certificates may be exchanged for other Certificates of a like aggregate percentage interest in the Trust, as
shown on the applicable Certificates, upon surrender of the Certificates to be exchanged at the office or agency maintained pursuant to Section 3.8. Whenever any Certificates are so surrendered for exchange, the AART Owner Trustee shall
execute on behalf of the Trust, authenticate and deliver (or shall cause Deutsche Bank Trust Company Americas, as its authenticating agent to authenticate and deliver) one or more Certificates dated the date of authentication by the AART Owner
Trustee or any authenticating agent. Such Certificates shall be delivered to the Holder making the exchange. 
 (f) Every Certificate
presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the AART Owner Trustee and the Certificate Registrar duly executed by the Holder or his attorney duly
authorized in writing and such other documents and instruments as may be required by Section 3.4(b). Each Certificate surrendered for registration of transfer or exchange shall be canceled and subsequently destroyed or otherwise disposed
of by the AART Owner Trustee or Certificate Registrar in accordance with its customary practice. 
 (g) The AART Owner Trustee or the
Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed and any other expenses of the AART Owner Trustee in connection with any transfer or exchange of Certificates. 

  
 7 








 (h) The Certificates may not be acquired by or for the account of a Benefit Plan other than an
“insurance company general account,” as defined in Prohibited Transaction Class Exemption 95-60, whose underlying assets include less than 25% plan assets and for which the purchase and holding of Certificates is eligible and satisfies all
conditions for relief under Prohibited Transaction Class Exemption 95-60. The Certificates also may not be acquired by or for the account of an employee benefit plan or plan that is not subject to the provisions of Title I of ERISA or
Section 4975 of the Code (including foreign or governmental plans) if such acquisition would result in a non-exempt prohibited transaction under, or a violation of, any applicable law that is substantially similar to Title I of ERISA or
Section 4975 of the Code. If requested to do so by the Depositor, each purchaser and transferee of a Certificate shall execute and deliver to the AART Owner Trustee an undertaking letter substantially in the form attached as Exhibit C.

 (i) The Certificates may (A) only be acquired by or for the account of a Person who is a United States Person (within the
meaning of Section 7701(a)(30) of the Code) and (B) not be acquired by or for the account of a Special Pass-Through Entity. For the purposes of this Section 3.5(i), “Special Pass-Through Entity” means a grantor
trust, S corporation, or partnership where more than 50% of the value of a beneficial owner’s interest in such pass through entity is attributable to the pass-through entity’s interest in the Certificates. 

Section 3.5 Mutilated, Destroyed, Lost or Stolen Certificates. 

(a) If (i) any mutilated Certificate is surrendered to the Certificate Registrar, or the Certificate Registrar receives evidence to its
satisfaction of the destruction, loss or theft of any Certificate, and (ii) there is delivered to the Certificate Registrar, the AART Owner Trustee and the Trust such security or indemnity as may be required by them to hold each of them
harmless, then, in the absence of notice to the Certificate Registrar or the AART Owner Trustee that such Certificate has been acquired by a protected purchaser, the AART Owner Trustee shall execute on behalf of the Trust and the AART Owner Trustee
shall authenticate and deliver (or shall cause Deutsche Bank Trust Company Americas, as its authenticating agent to authenticate and deliver), in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a replacement
Certificate of a like aggregate percentage interest in the Trust, as shown on the Certificate; provided, however, that if any such destroyed, lost or stolen Certificate, but not a mutilated Certificate, shall have become or within
seven (7) days shall be payable, then instead of issuing a replacement Certificate the AART Owner Trustee may make distributions to such destroyed, lost or stolen Certificate when so payable. 

(b) If, after the delivery of a replacement Certificate or payment in respect of a destroyed, lost or stolen Certificate pursuant to
Section 3.5(a), a protected purchaser of the original Certificate in lieu of which such replacement Certificate was issued presents for payment or distribution such original Certificate, the AART Owner Trustee shall be entitled to
recover such replacement Certificate (and any distributions or payments made with respect thereto) or such payment or distribution from the Person to whom it was delivered or any Person taking such replacement Certificate from such Person to whom
such replacement Certificate was delivered or any assignee of such Person, except a protected purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by
the AART Owner Trustee in connection therewith. 

  
 8 








 (c) In connection with the issuance of any replacement Certificate under this
Section 3.5, the AART Owner Trustee may require the payment by the Holder of such Certificate of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses
(including the fees and expenses of the AART Owner Trustee and the Certificate Registrar) connected therewith. 
 (d) Any duplicate
Certificate issued pursuant to this Section 3.5 in replacement of any mutilated, destroyed, lost or stolen Certificate shall constitute an original additional beneficial interest in the Trust, whether or not the mutilated, destroyed,
lost or stolen Certificate shall be found at any time or be enforced by anyone, and shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Certificates duly issued hereunder. 

(e) The provisions of this Section 3.5 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates. 
 Section 3.6 Persons Deemed
Certificateholders. Prior to due presentation of a Certificate for registration of transfer, the AART Owner Trustee or the Certificate Registrar may treat the Person in whose name any Certificate shall be registered in the Certificate Register
as the Certificateholder of such Certificate for the purpose of receiving distributions pursuant to Article V and for all other purposes whatsoever, and neither the AART Owner Trustee nor the Certificate Registrar shall be affected by any
notice to the contrary. 
 Section 3.7 Access to List of Certificateholders’ Names and Addresses. The Certificate Registrar
shall furnish or cause to be furnished to the Administrator and the Depositor, within fifteen (15) days after receipt by the Certificate Registrar of a request therefor from the Administrator or the Depositor, in writing, a list of the names
and addresses of the Certificateholders as of the most recent Record Date. Each Holder, by receiving and holding a Certificate, shall be deemed to have agreed not to hold any of the Administrator, the Depositor, the Certificate Registrar or the AART
Owner Trustee accountable by reason of the disclosure of its name and address, regardless of the source from which such information was derived. 

Section 3.8 Maintenance of Corporate Trust Office. The AART Owner Trustee shall maintain in the Borough of Manhattan, The City of
New York, an office or offices or agency or agencies where Certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon the AART Owner Trustee in respect of the Certificates and the other AART
Transaction Documents may be served. The AART Owner Trustee initially designates the offices of Deutsche Bank Trust Company Americas, 60 Wall Street, New York, New York 10005, as its principal office for such purposes. The AART Owner Trustee shall
give prompt written notice to the Depositor, to the Administrator, and to the Certificateholders of any change in the location of the Certificate Register or any such office or agency. 

Section 3.9 Appointment of Paying Agent. Except as otherwise provided in Section 5.2, the Paying Agent shall make
distributions to Certificateholders from the Certificate Distribution Account pursuant to Section 5.2 and shall report the amounts of such distributions to the AART Owner Trustee and the Administrator; provided, however,
that no such reports shall 

  
 9 








 
be required so long as the Depositor is the sole Certificateholder. Any Paying Agent shall have the revocable power to withdraw funds from the Certificate Distribution Account for the purpose of
making the distributions referred to above. The AART Owner Trustee may revoke such power and remove the Paying Agent if the AART Owner Trustee determines in its sole discretion that the Paying Agent shall have failed to perform its obligations under
this Agreement in any material respect. The Paying Agent shall initially be Deutsche Bank Trust Company Americas, and any co-paying agent chosen by Deutsche Bank Trust Company Americas, and acceptable to the AART Owner Trustee. Deutsche Bank Trust
Company Americas shall be permitted to resign as Paying Agent upon thirty (30) days’ written notice to the AART Owner Trustee. If Deutsche Bank Trust Company Americas shall no longer be the Paying Agent, the AART Owner Trustee shall
appoint a successor to act as Paying Agent (which shall be a bank or trust company). The AART Owner Trustee shall cause such successor Paying Agent or any additional Paying Agent appointed by the AART Owner Trustee to execute and deliver to the AART
Owner Trustee an instrument in which such successor Paying Agent or additional Paying Agent shall agree with the AART Owner Trustee that as Paying Agent, such successor Paying Agent or additional Paying Agent shall hold all sums, if any, held by it
for payment to the Certificateholders in trust for the benefit of the Certificateholders entitled thereto until such sums shall be paid to such Certificateholders. The Paying Agent shall return all unclaimed funds to the AART Owner Trustee and upon
removal of a Paying Agent such Paying Agent shall also return all funds in its possession to the AART Owner Trustee. The provisions of Sections 6.3, 6.6, 6.7 and 6.9 shall apply to the AART Owner Trustee also in its role
as Paying Agent or Certificate Registrar, for so long as the AART Owner Trustee shall act as Paying Agent or Certificate Registrar and, to the extent applicable, to any other paying agent, certificate registrar or authenticating agent appointed
hereunder. Any reference in this Agreement to the Paying Agent shall include any co-paying agent unless the context requires otherwise. 

Section 3.10 Depositor as Certificateholder. The Depositor in its individual or any other capacity may become the owner or pledgee
of Certificates and may otherwise deal with the AART Owner Trustee or its Affiliates as if it were not the Depositor.

Section 7.02 thereof, appoint a successor Administrator under the Administration Agreement or except as expressly provided in the AART Transaction Documents, sell the Secured Notes or any interest therein after the termination of the AART

AART Owner Trustee shall not have the power to commence a voluntary case under Title 11 of the United States Code or any successor provision relating to the Trust without the unanimous prior approval of all Certificateholders (including the
Depositor) and the delivery to the AART Owner Trustee by each such Certificateholder of a certificate certifying that such Certificateholder reasonably believes that the Trust is insolvent; provided, however, that under no
circumstances shall the AART Owner Trustee commence or join in commencing any such case prior to the date that is one year and one day after the termination of the Trust.

Documents, nor shall the AART Owner Trustee be obligated to follow any such direction, if given. The Certificateholders shall not and shall not direct the AART Owner Trustee to take action that would violate the provisions of Section 6.1

ARTICLE V 
 APPLICATION
OF TRUST FUNDS; CERTAIN DUTIES 
 Section 5.1 Establishment of Certificate Distribution Account. 

(a) Except as otherwise provided in Section 5.2, the Administrator, for the benefit of the Certificateholders, shall establish and
maintain in the name of the Trust an Eligible Deposit Account known as the Ally Auto Receivables Trust 2015-SN1 Certificate Distribution Account (the “Certificate Distribution Account”), bearing an additional designation clearly
indicating that the funds deposited therein are held for the benefit of the Certificateholders. 
 (b) The Trust shall possess all right,
title and interest in and to all funds on deposit from time to time in the Certificate Distribution Account and in all proceeds thereof. Except as otherwise provided herein, in the AART Indenture, or in the Administration Agreement, the Certificate
Distribution Account shall be under the sole dominion and control of the AART Owner Trustee for the benefit of the Certificateholders. If, at any time, the Certificate Distribution Account ceases to be an Eligible Deposit Account, the AART Owner
Trustee (or the Administrator on behalf of the AART Owner Trustee, if the Certificate Distribution Account is not then held by the AART Owner Trustee or an Affiliate thereof) shall within ten (10) Business Days (or such longer period, not to
exceed thirty (30) calendar days, as to which each Rating Agency may consent) establish a new Certificate Distribution Account as an Eligible Deposit Account and shall transfer any cash and/or any investments to such new Certificate
Distribution Account. 
 Section 5.2 Application of Trust Funds. 

(a) On each Distribution Date, the AART Owner Trustee or the Paying Agent shall distribute to the Certificateholders, on a pro rata basis,
amounts equal to the amounts deposited in the Certificate Distribution Account pursuant to Sections 4.05 and 8.01(b) of the Administration Agreement on or prior to such Distribution Date. Notwithstanding the foregoing or anything else to the
contrary in this Agreement or the other AART Transaction Documents, if and for so long as Certificates representing in the aggregate a 100% beneficial interest in the Trust are held by the Depositor or another subsidiary of Ally Bank, (i) no
Certificate Distribution Account shall be required to be established or maintained and (ii) all distributions and payments on the Certificates (including the final distribution as contemplated by Section 7.1(c)) required


  
 12 








 
hereunder or under the Administration Agreement shall be made directly to the Certificateholder by the AART Indenture Trustee (whether or not the Administration Agreement otherwise contemplates
deposit into the Certificate Distribution Account) and the AART Owner Trustee shall have no duty or liability to see to such distribution. 

(b) On each Distribution Date, the AART Owner Trustee shall send to each Certificateholder the statement provided to the AART Owner Trustee by
the Administrator pursuant to Section 4.07(a) of the Administration Agreement on such Distribution Date setting forth, among other things, the amount distributed on the Certificates and the Administration Fee with respect to such Distribution
Date or Monthly Period, as applicable; provided, however, that no such statement shall be required to be sent by the AART Owner Trustee if and for so long as the Depositor or another subsidiary of Ally Bank is the sole
Certificateholder. 
 (c) If any withholding tax is imposed on the Trust’s payment (or allocations of income) to a Certificateholder,
such tax shall reduce the amount otherwise distributable to the Certificateholder in accordance with this Section 5.2; provided, however, that the AART Owner Trustee or the Paying Agent shall not have an obligation to
withhold any such amount if and for so long as the Depositor is the sole Certificateholder. The AART Owner Trustee or the Paying Agent is hereby authorized and directed to retain from amounts otherwise distributable to the Certificateholders
sufficient funds for the payment of any tax that is legally owed by the Trust (but such authorization shall not prevent the AART Owner Trustee or the Paying 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 Certificateholder shall be treated as cash distributed to such Certificateholder 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. Certificateholder), the AART Owner Trustee or the Paying Agent may
in its sole discretion withhold such amounts in accordance with this Section 5.2(c). If a Certificateholder wishes to apply for a refund of any such withholding tax, the AART Owner Trustee or the Paying Agent shall reasonably cooperate
with such Certificateholder in making such claim so long as such Certificateholder agrees to reimburse the AART Owner Trustee or the Paying Agent for any out-of-pocket expenses incurred. 

(d) If the AART Indenture Trustee holds escheated funds for payment to the Trust pursuant to Section 3.3(e) of the AART Indenture, the
AART Owner Trustee shall, upon notice from the AART Indenture Trustee that such funds exist, submit on behalf of the Trust an Issuing Entity Order to the AART Indenture Trustee pursuant to Section 3.3(e) of the AART Indenture instructing the
AART Indenture Trustee to pay such funds to or at the order of the Depositor. 
 Section 5.3 Method of Payment. Subject to
Section 7.1(c), distributions required to be made to Certificateholders on any Distribution Date shall be made to each Certificateholder of record on the related Record Date by wire transfer, in immediately available funds, to the
account of such Holder at a bank or other entity having appropriate facilities therefore, if such Certificateholder shall have provided to the Certificate Registrar appropriate written instructions at least five (5) Business Days prior to such
Record Date or if not, by check mailed to such Certificateholder at the address of such Certificateholder appearing in the Certificate Register. 

  
 13 








 Section 5.4 Accounting and Reports to the Certificateholders, the Internal Revenue
Service and Others. The AART Owner Trustee shall maintain (or cause to be maintained) the books of the Trust on a calendar year basis on the accrual method of accounting, deliver to each Certificateholder, as may be required by the Code and
applicable Treasury Regulations or otherwise, such information as may be required to enable each Certificateholder to prepare its federal income tax return, file such tax returns relating to the Trust and make such elections as may from time to time
be required or appropriate under any applicable State or federal statute or rule or regulation thereunder so as to maintain the Trust’s characterization as an entity described in clause (a) of Section 2.11 for federal income tax
purposes, cause such tax returns to be signed in the manner required by law and collect or cause to be collected any withholding tax as described in and in accordance with Section 5.2(c) with respect to income or distributions to
Certificateholders. If the Trust were to become a partnership in accordance with Section 2.11 or the Internal Revenue Service were to contend successfully that the Trust is not a disregarded entity but is rather a partnership for federal
income tax purposes, the Trust shall allocate items of income, gain, deduction and loss to the partners of the Trust in accordance with their economic interests in the Trust. With respect to interest expense of the Trust, the Trust shall allocate to
the Certificateholders their share of the entire amount of such interest expense. 
 Section 5.5 Signature on Returns; Other Tax
Matters. The AART Owner Trustee shall sign on behalf of the Trust any and all tax returns of the Trust, unless applicable law requires a Certificateholder to sign such documents, in which case such documents shall be signed by the Depositor. To
the extent one may be required, the Depositor shall be the “tax matters partner” of the Trust pursuant to the Code.

VI

obligations shall be read into this Agreement.

Owner Trustee and conforming to the requirements of this Agreement in determining the truth of the statements and the correctness of the opinions contained therein; provided, however, that the AART Owner Trustee shall have examined
such certificates or opinions so as to determine compliance of the same with the requirements of this Agreement. 

  
 14 








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

faith by a Responsible Officer unless it is proved that the AART Owner Trustee was negligent in ascertaining the pertinent facts;

direct the AART Owner Trustee to take any action or themselves take any action that would violate the provisions of this Section 6.1. 

Section 6.2 Rights of AART Owner Trustee. The AART Owner Trustee is authorized and directed to execute and deliver the AART
Transaction Documents and each certificate or other document attached as an exhibit to or contemplated by the AART Transaction Documents to which the Trust is to be a party, in such form as the Depositor shall approve as evidenced conclusively by

willful misconduct or in the case of the inaccuracy of any representation or warranty contained in Section 6.6 and expressly made by the AART Owner Trustee. In particular, but not by way of limitation (and subject to the exceptions set
forth in the preceding sentence): 
 (a) the AART Owner Trustee shall at no time have any responsibility or liability for, or with respect
to, the legality, validity and enforceability of any Secured Note, or the perfection and priority of any security interest created by any Secured Note in any Lease Asset or the maintenance of any such perfection and priority, or for, or with respect

reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured or provided to it; 

(d) under no circumstances shall the AART Owner Trustee be liable for indebtedness evidenced by or arising under any of the AART Transaction
Documents, including the principal of and interest on the Notes; 
 (e) the AART Owner Trustee shall not be responsible for or in respect of

institute, conduct or defend any litigation under this Agreement or otherwise or in relation to this Agreement or any other AART Transaction Document, at the request, order or direction of any of the Certificateholders, unless such
Certificateholders have offered to the AART Owner Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities that may be incurred by the AART Owner Trustee therein or thereby; the right of the AART Owner Trustee to
perform any discretionary act enumerated in this Agreement or in any other AART Transaction Document shall not be construed as a duty, and the AART Owner Trustee shall not be answerable for other than its negligence or willful misconduct in the
performance of any such act; and 
 (h) notwithstanding anything to the contrary contained herein or in any other AART Transaction Document,

of the Trust or any other Person any filings, certificates, affidavits or other instruments required pursuant to the Sarbanes-Oxley Act of 2002 or the rules and regulations promulgated pursuant thereto, and the refusal to comply with any such
instructions shall not constitute a default or breach under any AART Transaction Document. In the event that the AART Owner Trustee, on behalf of the Trust, does not execute, deliver or certify any filings, certificates, affidavits or other
instruments required under the Sarbanes-Oxley Act of 2002, an Authorized Officer of the Administrator shall, on behalf of the Trust, execute, deliver or make such certification. 

Section 6.4 Action upon Instruction by Certificateholders. 

(a) Subject to Section 4.4, the Certificateholders may by written instruction direct the AART Owner Trustee in the management of
the Trust. Such direction may be exercised at any time by written instruction of the Certificateholders pursuant to Section 4.5. 

(b) Notwithstanding the foregoing, the AART Owner Trustee shall not be required to take any action hereunder or under any other AART
Transaction Document if the AART Owner Trustee shall have reasonably determined, or shall have been advised by counsel, that such action is likely to result in liability on the part of the AART Owner Trustee or is contrary to the terms hereof or of
any other AART Transaction Document or is otherwise contrary to law. 

  
 17 








 (c) Whenever the AART Owner Trustee is unable to decide between alternative courses of action
permitted or required by the terms of this Agreement or any other AART Transaction Document, or is unsure as to the application, intent, interpretation or meaning of any provision of this Agreement or any other AART Transaction Document, the AART
Owner Trustee shall promptly give notice (in such form as shall be appropriate under the circumstances) to the Certificateholders requesting instruction as to the course of action to be adopted, and, to the extent the AART Owner Trustee acts in good
faith in accordance with any such instruction received, the AART Owner Trustee shall not be liable on account of such action to any Person. If the AART Owner Trustee shall not have received appropriate instructions within ten (10) days of such
notice (or within such shorter period of time as reasonably may be specified in such notice or may be necessary under the circumstances) it may, but shall be under no duty to, take or refrain from taking such action which is consistent, in its view,
with this Agreement or any other AART Transaction Document, and as it shall deem to be in the best interests of the Certificateholders, and the AART Owner Trustee shall have no liability to any Person for any such action or inaction. 

Section 6.5 Furnishing of Documents. The AART Owner Trustee shall furnish to the Certificateholders, promptly upon receipt of a
written request therefor, duplicates or copies of all reports, notices, requests, demands, certificates, financial statements and any other instruments furnished to the AART Owner Trustee under the AART Transaction Documents. 

Section 6.6 Representations and Warranties of AART Owner Trustee. The AART Owner Trustee hereby represents and warrants to the
Depositor, for the benefit of the Certificateholders, that:

standing under the laws of the State of its incorporation. It has satisfied the eligibility requirements set forth in Section 6.13.

authorize the execution, delivery and performance by it of this Agreement.

Agreement (i) shall not violate any provision of any law or regulation governing the banking and trust powers of the AART Owner Trustee or any order, writ, judgment or decree of any court, arbitrator or governmental authority applicable to the
AART Owner Trustee or any of its assets, (ii) shall not violate any provision of the corporate charter or by-laws of the AART Owner Trustee or (iii) shall not violate any provision of, or constitute, with or without notice or lapse of
time, a default under, or result in the creation or imposition of any Lien on any properties included in the Trust pursuant to the provisions of any mortgage, indenture, contract, agreement or other undertaking to which it is a party, which
violation, default or Lien could reasonably be expected to have a materially adverse effect on the AART Owner Trustee’s performance or ability to perform its duties as AART Owner Trustee under this Agreement or on the transactions contemplated
in this Agreement. 

  
 18 








 (d) This Agreement has been duly executed and delivered by the AART Owner Trustee and constitutes
the legal, valid and binding agreement of the AART Owner Trustee, enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, or other similar laws affecting the enforcement of
creditors’ rights in general and by general principles of equity, regardless of whether such enforceability is considered in a proceeding in equity or at law. 

Section 6.7 Reliance; Advice of Counsel. 

(a) The AART Owner Trustee shall incur no liability to anyone in acting upon any signature, instrument, notice, resolution, request, consent,
order, certificate, report, opinion, bond or other document or paper believed by it to be genuine and believed by it to be signed by the proper party or parties and need not investigate any fact or matter in any such document. The AART Owner Trustee
may accept a certified copy of a resolution of the board of directors or other governing body of any corporate party as conclusive evidence that such resolution has been duly adopted by such body and that the same is in full force and effect. As to
any fact or matter the method of the determination of which is not specifically prescribed herein, the AART Owner Trustee may for all purposes hereof rely on a certificate, signed by the president or any vice president or by the treasurer or other
authorized officers of the relevant party, as to such fact or matter, and such certificate shall constitute full protection to the AART Owner Trustee for any action taken or omitted to be taken by it in good faith in reliance thereon. 

(b) In the exercise or administration of the trusts hereunder and in the performance of its duties and obligations under this Agreement or the
other AART Transaction Documents, the AART Owner Trustee may act directly or through its agents, attorneys, custodians or nominees (including the granting of a power of attorney to officers of Deutsche Bank Trust Company Americas to execute and
deliver any AART Transaction Documents, Certificate, Note or other documents related thereto on behalf of the AART Owner Trustee) pursuant to agreements entered into with any of them, and the AART Owner Trustee shall not be liable for the conduct or
misconduct of such agents, attorneys, custodians or nominees if such agents, attorneys, custodians or nominees shall have been selected by the AART Owner Trustee with reasonable care; and may consult with counsel, accountants and other skilled
professionals to be selected with reasonable care and employed by it. The AART Owner Trustee shall not be liable for anything done, suffered or omitted in good faith by it in accordance with the opinion or advice of any such counsel, accountants or
other such Persons and not contrary to this Agreement or any other AART Transaction Document. 
 Section 6.8 AART Owner Trustee May
Own Certificates and Notes. Deutsche Bank Trust Company Delaware or any successor AART Owner Trustee in its individual or any other capacity may become the owner or pledgee of Certificates or Notes and may deal with the Depositor, the AART
Indenture Trustee and the Administrator in transactions in the same manner as it would have if it were not the AART Owner Trustee. 

Section 6.9 Compensation and Indemnity. The AART Owner Trustee shall receive as compensation for its services hereunder such fees
as have been separately agreed upon before the date hereof between the Administrator and the AART Owner Trustee, and the AART Owner Trustee, any paying agent, registrar, authenticating agent or co-trustee shall be entitled to be


  
 19 








 
reimbursed by the Administrator for its other reasonable expenses hereunder, including the reasonable compensation, expenses and disbursements of such agents, custodians, nominees,
representatives, experts and external counsel as the AART Owner Trustee may employ in connection with the exercise and performance of its rights and its duties hereunder. The Administrator shall indemnify the AART Owner Trustee, any paying agent,
registrar, authenticating agent or co-trustee and its successors, assigns, agents and servants in accordance with the provisions of Section 6.01 of the Administration Agreement. The indemnities contained in this Section 6.9 shall
survive the resignation or removal of the AART Owner Trustee or the termination of this Agreement. Any amounts paid to the AART Owner Trustee pursuant to this Article VI shall be deemed not to be a part of the AART Owner Trust Estate
immediately after such payment. 
 Section 6.10 Replacement of AART Owner Trustee. 

(a) The AART Owner Trustee may give notice of its intent to resign and be discharged from the trusts hereby created by giving notice thereof to
the Administrator provided, however, that no such resignation shall become effective, and the AART Owner Trustee shall not resign, prior to the time set forth in Section 6.10(c). If no successor AART Owner Trustee shall
have been appointed pursuant to Section 6.10(b) and have accepted such appointment within thirty (30) days after the giving of such notice, the AART Owner Trustee giving such notice may petition any court of competent jurisdiction
for the appointment of a successor AART Owner Trustee. The Administrator shall remove the AART Owner Trustee if: 
 (i) the AART Owner

successor AART Owner Trustee) and shall pay all fees owed to the outgoing AART Owner Trustee. 
 (c) Any resignation or removal of the AART
Owner Trustee and appointment of a successor AART Owner Trustee pursuant to any of the provisions of this Section 6.10 shall not become effective and no such resignation shall be deemed to have occurred until a written acceptance of

the 

  
 20 








 
AART Owner Trustee and the appointment of a successor AART Owner Trustee, such costs shall reduce the amount otherwise distributable to the AART Certificateholder in accordance with

with all the rights, powers, duties and obligations of its predecessor under this Agreement, with like effect as if originally named as AART Owner Trustee. The Administrator shall provide notice of such resignation or removal of the AART Owner
Trustee to each of the Rating Agencies. 
 (d) The predecessor AART Owner Trustee shall upon payment of its fees and expenses deliver to the
successor AART Owner Trustee all documents and statements and monies held by it under this Agreement. The Administrator and the predecessor AART Owner Trustee shall execute and deliver such instruments and do such other things as may reasonably be

converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the AART Owner Trustee shall be a party, or any Person succeeding to all or substantially all of the corporate trust
business of the AART Owner Trustee, shall be the successor of the AART Owner Trustee hereunder, provided such Person shall be eligible pursuant to Section 6.13, and without the execution or filing of any instrument or any further act on
the part of any of the parties hereto. 
 Section 6.12 Appointment of Co-Trustee or Separate Trustee. 

(a) Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirement of any jurisdiction
in which any part of the AART Owner Trust Estate or any Secured Note may at the time be located, the Administrator and the AART Owner Trustee acting jointly shall have the power and shall, at the expense of the Administrator, execute and deliver all
instruments to appoint one or more Persons approved by the AART Owner Trustee to act as co-trustee, jointly with the AART Owner Trustee, or as separate trustee or trustees, of all or any part of the AART Owner Trust Estate, and to vest in such
Person (in the name of the Trust and not in such Person’s name for the Trust, except to the extent otherwise required by, and in accordance with, Section 2.8), in such capacity, such title to the Trust, or any part thereof, and,
subject to the other provisions of this Section 6.12, such powers, duties, obligations, rights and trusts as the Administrator and the AART Owner Trustee may consider necessary or desirable. If the Administrator shall not have joined in
such appointment within fifteen (15) days after the receipt by it of a request so to do, the AART Owner Trustee alone shall have the power to make such appointment. No co-trustee or separate 

  
 21 








 
trustee under this Agreement shall be required to meet the terms of eligibility as a successor trustee pursuant to Section 6.13 and no notice of the appointment of any co-trustee or
separate trustee shall be required pursuant to Section 6.10. 
 (b) Each separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and conditions: 
 (i) all rights, powers, duties and
obligations conferred or imposed upon the AART Owner Trustee shall be conferred upon and exercised or performed by the AART Owner Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee
is not authorized to act separately without the AART Owner Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed, the AART Owner Trustee shall be incompetent
or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such
separate trustee or co-trustee, but solely at the direction of the AART Owner Trustee; 
 (ii) no trustee under this Agreement shall be
personally liable by reason of any act or omission of any other trustee under this Agreement; and 
 (iii) the Administrator and the AART
Owner Trustee acting jointly may at any time accept the resignation of or remove any separate trustee or co-trustee. 
 (c) Any notice,
request or other writing given to the AART Owner Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or
co-trustee shall refer to this Agreement and the conditions of this Article VI. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of
appointment, either jointly with the AART Owner Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the
liability of, or affording protection to, the AART Owner Trustee. Each such instrument shall be filed with the AART Owner Trustee and a copy thereof given to the Administrator. 

(d) Any separate trustee or co-trustee may at any time appoint the AART Owner Trustee as its agent or attorney-in-fact with full power and
authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its
estates, properties, rights, remedies and trusts shall vest in and be exercised by the AART Owner Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

shall publish reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purpose of this Section 6.13, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the AART Owner Trustee shall cease to be eligible in accordance with the provisions of this
Section 6.13, the AART Owner Trustee shall resign immediately in the manner and with the effect specified in Section 6.10.

the Depositor or the Administrator to facilitate compliance with Article XII of the AART Indenture by the Ally Parties.

 TERMINATION OF TRUST AGREEMENT 

Section 7.1 Termination of Trust Agreement. 

(a) The Trust shall dissolve in accordance with Section 3808 of the Statutory Trust Act immediately prior to the final distribution by the
AART Owner Trustee of all monies or other property or proceeds of the AART Owner Trust Estate in accordance with the terms of the AART Indenture, the Administration Agreement (including the exercise by the Administrator of its option to purchase the
Secured Notes pursuant to Section 8.01(a) of the Administration Agreement), and Article V. The bankruptcy, liquidation, dissolution, death or incapacity of any Certificateholder shall not (x) operate to terminate this Agreement or
the Trust, (y) entitle such Certificateholder’s legal representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding up of all or any part of the Trust or the AART Owner Trust
Estate, or (z) otherwise affect the rights, obligations and liabilities of the parties hereto. 
 (b) Neither the Depositor nor any
Certificateholder shall be entitled to revoke or terminate the Trust or this Agreement. 
 (c) Subject to Section 5.2(a), notice
of any dissolution of the Trust, specifying the Distribution Date upon which the Certificateholders shall surrender their Certificates to the Paying Agent for payment of the final distribution and cancellation, shall be given by the AART Owner
Trustee by letter to Certificateholders mailed within five (5) Business Days of receipt of notice of such termination from the Administrator given pursuant to Section 8.01(c) of the Administration Agreement, stating: (i) the
Distribution Date upon or with respect to which final payment of the Certificates shall be made upon presentation and surrender of the Certificates at the office of the Paying Agent therein designated; (ii) the amount of any such final payment;
and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the office of the Paying Agent therein specified. The AART Owner
Trustee shall give such notice to the 

  
 23 








 
Certificate Registrar (if other than the AART Owner Trustee) and the Paying Agent at the time such notice is given to Certificateholders. Upon presentation and surrender of the Certificates, the
Paying Agent shall cause to be distributed to Certificateholders amounts distributable on such Distribution Date pursuant to Section 5.2. 

(d) If all of the Certificateholders shall not surrender their Certificates for cancellation within six (6) months after the date
specified in the written notice referred to in Section 7.1(c), the AART Owner Trustee shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final
distribution with respect thereto. If within one (1) year after the second notice all the Certificates shall not have been surrendered for cancellation, the AART Owner Trustee may take appropriate steps, or may appoint an agent to take
appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets that shall remain subject to this Agreement. Subject to applicable laws
with respect to escheat of funds, any funds remaining in the Trust after exhaustion of such remedies in the preceding sentence shall be deemed property of the Depositor and distributed by the AART Owner Trustee to the Depositor, and the AART Owner
Trustee shall have no further liability to the Certificateholders with respect thereto. 
 (e) Upon the winding up and termination of the
Trust in accordance with Section 3808 of the Statutory Trust Act and this Section 7.1, at the written direction and expense of the Certificateholders, the AART Owner Trustee shall cause the Certificate of Trust to be canceled by
filing a certificate of cancellation with the Secretary of State in accordance with the provisions of Section 3810 of the Statutory Trust Act. Thereupon, this Agreement (other than Sections 6.9, 9.8 and 9.9) and the Trust
shall terminate.

Agreement may also be amended from time to time by the Depositor and the AART Owner Trustee with the consent of Noteholders whose Notes evidence not less than a majority of the Outstanding Amount of the Controlling Class as of the close of the
preceding Distribution Date and, if any Person other than the Depositor or an Affiliate of the Depositor holds any Certificates, the consent of Certificateholders whose Certificates evidence not less than a majority of the Voting Interests as of the
close of the preceding Distribution Date (which consent, whether given pursuant to this Section 8.2 or pursuant to any other provision of this Agreement, shall be conclusive and binding on such Person and on all future Holders of such
Notes or Certificates and of any Notes or Certificates issued upon the transfer thereof or in exchange thereof or in lieu thereof whether or not notation of such consent is made upon the Notes or Certificates) 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 Noteholders or the Certificateholders; provided, however, that no such amendment shall
(a) without the consent of the holder of the affected Note, increase or reduce the interest rate or principal amount of any Note or change any Distribution Date or the Final Scheduled Distribution Date of any Note or distributions on the

Certificateholders and Unaffiliated Certificateholders provided for in this Agreement or in any other AART Transaction Document) and of evidencing the authorization of the execution thereof by Certificateholders and Unaffiliated Certificateholders
shall be subject to such reasonable requirements as the AART Owner Trustee may prescribe. 
 (c) Promptly after the execution of any
amendment to the Certificate of Trust, the AART Owner Trustee shall cause the filing of such amendment with the Secretary of State. 

  
 25 








 (d) Prior to the execution of any amendment to this Agreement or the Certificate of Trust, the
AART Owner Trustee shall be entitled to receive and conclusively rely upon an Opinion of Counsel stating that the execution of such amendment by it is authorized or permitted by this Agreement. The AART Owner Trustee may, but shall not be obligated
to, enter into any such amendment which affects the AART Owner Trustee’s own rights, duties or immunities under this Agreement or otherwise.

 26 








 Section 9.6 Counterparts. This Agreement may be executed by the parties hereto in
separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts shall together constitute one and the same instrument. 

Section 9.7 Successors and Assigns.

authority of competent jurisdiction, and, as a result, a Certificateholder is deemed to have an interest in any assets of the Depositor or any Affiliate of the Depositor other than the Trust (“other assets”), each Certificateholder and
Certificate Owner agrees that (i) its claim against any such other assets shall be, and hereby is, subject and subordinate in all respects to the rights of other Persons to whom rights in the other assets have been expressly granted
(“entitled Persons”), including to the payment in full of all amounts owing to such entitled Persons, and (ii) the covenant set forth in the preceding clause (i) constitutes a “subordination agreement” within the

 ALLY AUTO RECEIVABLES TRUST 2015-SN1 

ASSET BACKED CERTIFICATE 

evidencing a fractional undivided interest in the Trust, as defined below, the property of which includes the Secured Notes
sold to the Trust by Ally Auto Assets LLC. 
 (This Certificate does not represent an interest in or obligation of Ally Auto
Assets LLC or Ally Financial Inc. or any of their respective affiliates, except to the extent described in the AART Transaction Documents.) 

THIS CERTIFIES THAT                     is
the registered owner of a nonassessable, fully-paid, fractional undivided interest in Ally Auto Receivables Trust 2015-SN1 (the “Trust”) formed by Ally Auto Assets LLC, a Delaware limited liability company (the
“Depositor”). 
 The Trust was created pursuant to a trust agreement, dated as of February 20, 2015 (as amended and
restated as of March 31, 2015 and as it may be amended from time to time, the “Trust Agreement”), between the Depositor and Deutsche Bank Trust Company Delaware, as owner trustee (the “AART Owner Trustee”), a
summary of certain of the pertinent provisions of which is set forth below. To the extent not otherwise defined herein, the capitalized terms used herein have the meanings assigned to them or incorporated by reference in the Trust Agreement. 

This Certificate is one of the duly authorized Certificates designated as Asset Backed Certificates (the “Certificates”).
This Certificate is issued under and is subject to the terms, provisions and conditions of the Trust Agreement, the terms of which are incorporated herein by reference and made a part hereof, to which Trust Agreement the holder of this Certificate
by virtue of the acceptance hereof assents and by which such holder is bound. 
 Under the Trust Agreement, there shall be distributed on
the 20th day of each month or, if such 20th day is not a Business Day, the next Business Day, commencing on May 20, 2015 (each, a
“Distribution Date”), to the Person in whose name this Certificate is registered on the related Record Date (as defined below), such amount as is provided in the AART Transaction Documents. The “Record Date,” with
respect to any Distribution Date, means the last day of the preceding Monthly Period. 
 The distributions in respect of this Certificate
are payable in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. All payments made by the Trust with respect to this Certificate shall be applied in respect of
this Certificate. 

  
 Ex. A-3 








 The holder of this Certificate acknowledges and agrees that its rights to receive distributions
in respect of this Certificate are subordinated to the rights of the Noteholders as and to the extent described in the Administration Agreement. 

It is the intent of the Depositor, the AART Owner Trustee and the Certificateholders that, for purposes of federal income, State and local
income and franchise taxes, and any other taxes imposed upon, measured by or based upon gross or net income, the Trust shall be treated as either (A) a division of an entity that is not disregarded as a separate entity for federal income tax
purposes, or (B) a partnership if the Certificates are owned by more than one Person (as long as (1) such Persons are not disregarded as separate entities for federal income tax purposes and (2) if such Persons are disregarded as
separate entities for federal income tax purposes, such Persons are not treated as a division of the same Person). Except as otherwise required by appropriate taxing authorities, the Depositor and the other Certificateholders by acceptance of a
Certificate agree to treat, and to take no action inconsistent with the treatment of, the Certificates for such tax purposes as interests in such a disregarded entity or partnership as described in the previous sentence. 

Each Certificateholder or Certificate Owner by its acceptance of a Certificate (or an interest therein) covenants and agrees that such
Certificateholder or Certificate Owner shall not (nor shall it join with or solicit another person to), prior to the date which is one year and one day after the termination of the Trust and of each other trust heretofore formed by the Depositor,
acquiesce, petition or otherwise invoke or cause the Depositor, the AART Owner Trustee or the Trust to invoke in any court or governmental authority for the purpose of commencing or sustaining a case against the Depositor or the Trust under any
federal or State bankruptcy, insolvency or similar law or appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or other similar official of the Depositor or the Trust or any substantial part of its property, or ordering the
winding up or liquidation of the affairs of the Depositor or the Trust under a federal or State bankruptcy or insolvency proceeding. 

Except as otherwise provided in the Trust Agreement, distributions on this Certificate shall be made as provided in the Trust Agreement by the
AART Owner Trustee by wire transfer or check mailed to the Certificateholder of record in the Certificate Register without the presentation or surrender of this Certificate or the making of any notation hereon. Except as otherwise provided in the
Trust Agreement and notwithstanding the above, the final distribution on this Certificate shall be made after due notice by the AART Owner Trustee of the pendency of such distribution and only upon presentation and surrender of this Certificate at
the office maintained for such purpose by the AART Owner Trustee in the Borough of Manhattan, The City of New York. 
 Reference is hereby
made to the further provisions of this Certificate set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place. 

Unless the certificate of authentication hereon shall have been executed by an authorized officer of the AART Owner Trustee by manual
signature, this Certificate shall not entitle the holder hereof to any benefit under the Trust Agreement or the Administration Agreement or be valid for any purpose.

 REVERSE OF CERTIFICATE 

The Certificates do not represent an obligation of, or an interest in, the Depositor, the Administrator, Ally Bank, Ally Financial Inc., the
AART Indenture Trustee, the AART Owner Trustee or any Affiliates of any of them and no recourse may be had against such parties or their assets, except as may be expressly set forth or contemplated herein or in the Trust Agreement or the other AART
Transaction Documents. In addition, this Certificate is not guaranteed by any governmental agency or instrumentality and is limited in right of payment to certain collections and recoveries with respect to the Secured Notes (and certain other
amounts), all as more specifically set forth herein and in the other AART Transaction Documents. A copy of each of the other AART Transaction Documents may be examined during normal business hours at the principal office of the Depositor, and at
such other places, if any, designated by the Depositor, by any Certificateholder upon written request. In the event of any conflict between the terms of this Certificate and the terms of the other AART Transaction Documents, the terms of the other
AART Transaction Documents shall govern. 
 The Trust Agreement permits, with certain exceptions provided therein, the amendment thereof and
the modification of the rights and obligations of the Depositor and the rights of the Certificateholders under the Trust Agreement at any time by the Depositor and the AART Owner Trustee with the consent of the Holders of the Notes evidencing not
less than a majority of the Outstanding Amount of the Controlling Class as of the close of the preceding Distribution Date and, if any Person other than the Depositor or an Affiliate of the Depositor holds any Certificates, the consent of
Certificateholders whose Certificates evidence not less than a majority of the Voting Interests as of the close of the preceding Distribution Date. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and
on all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Trust Agreement also permits the
amendment thereof, in certain circumstances, without the consent of the Holders of any of the Certificates or the Notes. 
 As provided in
the Trust Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registerable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies of the
Certificate Registrar maintained by the AART Owner Trustee in The City of New York, accompanied by a written instrument of transfer in form satisfactory to the AART Owner Trustee and the Certificate Registrar duly executed by the Holder hereof or
such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates evidencing the same percentage interest in the Trust will be issued to the designated transferee. The initial Certificate Registrar appointed under
the Trust Agreement is Deutsche Bank Trust Company Americas, New York, New York. 
 The Certificates are issuable only as registered
Certificates. As provided in the Trust Agreement and subject to certain limitations set forth therein, Certificates are exchangeable for new Certificates of the same aggregate percentage interested requested by the Holder surrendering the same. No
service charge shall be made for any such registration of transfer or exchange, but the AART Owner Trustee or the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge payable in connection therewith.

 The AART Owner Trustee, the Certificate Registrar and any agent of the AART Owner Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the AART Owner Trustee, the Certificate Registrar or any such agent shall be affected by any notice to the
contrary. 
 The obligations and responsibilities created by the Trust Agreement and the Trust created thereby shall terminate in accordance
with Article VII of the Trust Agreement.
