 The foregoing grants are made in trust to secure (a) the Issuing Entity’s obligations

 The Indenture Trustee, as indenture trustee on behalf of the Noteholders, hereby acknowledges the foregoing grants, accepts

ARTICLE I 
 CREATION OF
SERIES 2015-3 NOTES 
 SECTION 1.01 Designation. 

(a) There is hereby created a Series of Notes to be issued by the Issuing Entity on the Closing Date pursuant to the Indenture and this
Indenture Supplement to be known as the “Series 2015-3 Asset Backed Notes” or the “Series 2015-3 Notes.” The Series 2015-3 Notes shall be issued in five Classes, the first shall be known as the “Series
2015-3 Fixed Rate Asset Backed Notes, Class A,” the second shall be known as the “Series 2015-3 Fixed Rate Asset Backed Notes, Class B,” the third shall be known as the “Series 2015-3 Fixed Rate Asset Backed Notes,
Class C,” the fourth shall be known as the “Series 2015-3 Fixed Rate Asset Backed Notes, Class D,” and the fifth shall be known as the “Series 2015-3 Asset Backed Equity Notes, Class E.” The Series 2015-3
Notes shall be due and payable on the Series 2015-3 Legal Maturity Date. 
 (b) Series 2015-3 shall be a Nonoverconcentration Series. Series
2015-3 shall be in Excess Interest Sharing Group One and in Principal Sharing Group One. Series 2015-3 shall not be a Shared Enhancement Series or in an Interest Reallocation Group. Series 2015-3 shall not be subordinated to any other Series. 

(c) The Series 2015-3 Notes are “Notes” and this Indenture Supplement is an “Indenture Supplement” for all purposes under
the Indenture. If any provision of the Series 2015-3 Notes or this Indenture Supplement conflicts with or is inconsistent with any provision of the Indenture, the provisions of the Series 2015-3 Notes or this Indenture Supplement, as the case may
be, control. 
 (d) Each term defined in Section 2.01 of this Indenture Supplement relates only to Series 2015-3 and this
Indenture Supplement and to no other Series or Indenture Supplements. 
 (e) Notwithstanding anything to the contrary in the Indenture, the
Series 2015-3 Notes, other than the Class E Note, shall be issued in fully registered form in minimum amounts of $1,000 and in integral multiples of $1,000 in excess thereof (except that one Note from each such class may be issued in a different
amount so long as such amount exceeds $1,000); provided that the minimum amounts of the Series 2015-3 Notes, other than the Class E Note, 

  
 2 








 
shall be subject to the restrictions set forth in Section 4.14. The Class E Note shall be issued in fully registered form in a principal amount equal to the Class E Note Principal
Balance. The Class E Note will be issuable in a minimum denomination of 100% of the Class E Note Principal Balance. 

SECTION 1.02 Reopening of Class or Tranche of Notes. 

The Depositor may from time to time, with notice to the Rating Agencies but without notice to, or the consent of, the holders of a Class or
Tranche of Series 2015-3 Notes, create and issue additional Series 2015-3 Notes equal in rank to any Class or Tranche of Series 2015-3 Notes previously offered in all respects or in all respects, except for the payment of interest accruing prior to
the Issuance Date of such additional Series 2015-3 Notes in a Class or Tranche of Series 2015-3 Notes or except for the first payment of interest following the Issuance Date of such additional Series 2015-3 Notes in a Class or Tranche of Series
2015-3 Notes. This is called a “reopening.” When issued, the additional Series 2015-3 Notes of a Class or Tranche shall be equally and ratably entitled to the benefits of the Indenture and this Indenture Supplement applicable to
those Series 2015-3 Notes with the other Outstanding Notes of that Class or Tranche without preference, priority or distinction. These additional Series 2015-3 Notes may be consolidated and form a single Class or Tranche with the previously issued
Series 2015-3 Notes and shall have the same terms as to status, redemption or otherwise as the previously issued Series 2015-3 Notes.

(h) The Controlled Accumulation Period is scheduled to commence on the first day of the November 2017 Collection Period; provided,
however, that, if the Accumulation Period Length (determined as described below) is less than six Collection Periods, the date on which the Controlled Accumulation Period actually commences shall be delayed to the first day of the Collection
Period that is the number of whole Collection Periods before the Series 2015-3 Expected Maturity Date at least equal to the Accumulation Period Length and, as a result, the number of Collection Periods in the Controlled Accumulation Period shall at
least equal the Accumulation Period Length. On or before each Determination Date beginning with the Determination Date in the October 2017 Collection Period and ending when the Controlled Accumulation Period begins, the Servicer shall determine the
“Accumulation Period Length” as of such Determination Date, which shall equal the number of whole Collection Periods such that the sum of the Accumulation Period Factors for each Collection Period during such period shall be equal

 27 








 (j) Notwithstanding any other provision of this Indenture Supplement or the Indenture, if any
amount is required to be deposited into any Series Account or other account pursuant to this Indenture Supplement and all or part of the amount of such deposit is to be deposited into another account or otherwise distributed on that date, such
amount may be deposited directly into the applicable subsequent account or distributed directly to the applicable recipient without first being deposited into the initial Series Account or account. 

(k) Note Defeasance Account. With respect to each Collection Period, no later than 10:00 am Central time on any Business Day of such
Collection Period, including pursuant to Section 4.04(d) and (e), the Servicer, at the direction of the Depositor, shall and, the Servicer may (if Ally Financial or an Affiliate of Ally Financial is the Servicer), in its
discretion, specify to the Indenture Trustee an amount of Available Series Interest Collections and Available Series Principal Collections to be withdrawn from the Collection Account or, with respect to any amounts on deposit in the Note
Distribution Account constituting Available Series Principal Collections, the Note Distribution Account, and deposited into the Note Defeasance Account. With respect to any Collection Period, the aggregate of such amounts deposited into the Note
Defeasance Account, as reasonably calculated by the Servicer (i) with respect to each Collection Period (or portion thereof) that does not occur during a Controlled Accumulation Period or Early Amortization Period, shall not be in excess of the
lesser of (1) Available Series Interest Collections for such Collection Period plus Reallocated Principal Collections for the related Distribution Date less the Monthly Servicing Fee for such Collection Period and (2) the aggregate amount
necessary to make the allocations and distributions required by clauses (ii) through (v) of Section 4.04(a) and (ii) with respect to each Collection Period (or portion thereof) that occurs during a Controlled Accumulation
Period or Early Amortization Period, shall not be in excess of the lesser of (1) the aggregate of the Available Series Interest Collections for such Collection Period, plus the Available Series Principal Collections for such Collection Period,
less the Monthly Servicing Fee for such Collection Period and (2) the aggregate amount necessary to make the allocations and distributions required by (x) clauses (ii) through (v) of Section 4.04(a) and (y) Section
4.04(d) or 4.04(e), as applicable, during such Collection Period. The Servicer shall not have any liability for any such calculation made in good faith. Any amount on deposit in the Note Defeasance Account on any Distribution Date (after
giving effect to all deposits therein or withdrawals therefrom on such Distribution Date) shall remain on deposit in the Note Defeasance Account for distribution on the next Distribution Date in accordance with this Indenture Supplement. 

(l) No later than 10:00 am Central time on each Business Day on which amounts are to be withdrawn from the Collection Account or the Note
Distribution Account and deposited into the Note Defeasance Account pursuant to Section 4.04(k), the Servicer shall notify the Indenture Trustee of the sources and amounts to be deposited in the Note Defeasance Account on such Business
Day and the Indenture Trustee shall transfer such amount from the Collection Account or the Note Distribution Account, as applicable, to the Note Defeasance Account. 

(m) If an increase in the Subordination Factor is to occur on the next Distribution Date, the Required Nonoverconcentration Pool Balance for
purposes of Section 8.3 of the 

  
 28 








 
Indenture as of such Distribution Date and on each subsequent date until the Distribution Date on which such increase takes effect shall be calculated as if the increase in the Subordination
Factor has already occurred. 
 SECTION 4.05 Series Charge-Offs. 

(a) On each Determination Date, the Servicer shall calculate the Series Defaulted Amount, if any, for the related Distribution Date. If the
Series Defaulted Amount for any Distribution Date exceeds the sum of: 
 (i) the Available Series Interest Collections for
such Distribution Date applied to fund such Series Defaulted Amount pursuant to Section 4.04(a)(vi); 
 (ii) the
Excess Interest Collections available from other outstanding Series in Excess Interest Sharing Group One for such Distribution Date applied to fund such Series Defaulted Amount pursuant to Section 4.04(a)(vi) in accordance with
Section 4.04(b)(i); 
 (iii) the Reserve Fund Available Amount for such Distribution Date applied to fund such
Series Defaulted Amount pursuant to Section 4.04(a)(vi) in accordance with Section 4.04(b)(ii) (after giving effect to the application of such amounts to items (i) through (v) in Section 4.04(a)); and;

 (iv) the amount of Servicer Advances for such Distribution Date applied to fund such Series Defaulted Amount pursuant to
Section 4.04(a)(vi) in accordance with Section 4.04(b)(iv); 
 then, a “Series
Charge-Off” in the amount of such excess shall exist for such Distribution Date and shall reduce the Invested Amount. 

(b) The reduction in the Invested Amount for such Distribution Date due to such Series Charge-Off
shall be allocated as follows: 
 (i) first, the Class E Invested Amount shall be reduced by the amount of such reduction
until the Class E Invested Amount is reduced to zero; then 
 (ii) second, the Class D Invested Amount shall be reduced by
any remaining amount until the Class D Invested Amount is reduced to zero; then 
 (iii) third, the Class C Invested Amount
shall be reduced by any remaining amount until the Class C Invested Amount is reduced to zero; then 
 (iv) fourth, the Class
B Invested Amount shall be reduced by any remaining amount until the Class B Invested Amount is reduced to zero; and then

 SECTION 4.06 Reallocated Principal Collections. 

On each Distribution Date, the Servicer shall apply, or direct the Indenture Trustee by written instruction to the Indenture Trustee to apply
the portion of Reallocated Principal Collections specified in Section 4.04(b)(iii) from the following sources and in the following order of priority, (i) first, Additional Available Series Principal Collections for that Distribution
Date available in accordance with Section 4.04(f), (ii) second, Series Principal Collections for that date, (iii) third, amounts on deposit in the Note Defeasance Account (to the extent such funds are used to cover shortfalls

Class D Notes, then for the Class C Notes, then for the Class B Notes and then for the Class A Notes), but not in excess of the amounts specified in the definition of “Reallocated Principal Collections,” in accordance with
Section 4.04(b)(iii). If, on any Distribution Date, Reallocated Principal Collections for such Distribution Date are so applied, then, the Invested Amount shall be reduced by the amount of such application and, if such amounts are from
withdrawals from the Note Distribution Account or the Note Defeasance Account, those amounts shall be deemed not to have been allocated or deposited into the Note Distribution Account or the Note Defeasance Account, as applicable, for purposes of
this Indenture Supplement. The reduction in the Invested Amount for such Distribution Date due to the application of such Reallocated Principal Collections shall be allocated as follows: 

(a) first, the Class E Invested Amount shall be reduced by the amount of such reduction until the Class E Invested Amount is reduced to zero;
then 
 (b) second, the Class D Invested Amount shall be reduced by any remaining amount until the Class D Invested Amount is reduced to
zero; then 
 (c) third, the Class C Invested Amount shall be reduced by any remaining amount until the Class C Invested Amount is reduced

Excess Interest Sharing Group One for any Distribution Date shall be allocated to Series 2015-3 in an amount equal to the product of (i) the aggregate amount of Excess Interest Collections with respect to all the Excess Interest Sharing Series
in Excess Interest Sharing Group One for such Distribution Date and (ii) a fraction, the numerator of which is the Interest Collections Shortfall for Series 2015-3 for such Distribution Date and the


  
 30 








 
denominator of which is the aggregate amount of Interest Collections Shortfalls for all the Excess Interest Sharing Series in Excess Interest Sharing Group One for such Distribution Date. The
“Interest Collections Shortfall” for Series 2015-3 for any Distribution Date shall equal the excess, if any, of (a) the full amount required to be paid, without duplication, pursuant to clauses (i) through
(xii) of Section 4.04(a) on such Distribution Date, over (b) the Available Series Interest Collections for such Distribution Date. The maximum amount of “Excess Interest Collections” with respect to
Series 2015-3 for any Distribution Date available for other Series in Excess Sharing Group One shall equal the excess, if any, of (a) the Available Series Interest Collections for such Distribution Date over (b) the full amount required to

the amount previously deposited or distributed pursuant to that subsection, and (c) for any date in the Early Amortization Period, the amount to be deposited or distributed pursuant to Section 4.04(e) over the amount previously
deposited or distributed pursuant to that subsection. The “Shared Principal Collections” with respect to Series 2015-3 for any date shall equal the excess, if any, of (a) the Available Series Principal Collections for such date
(without giving effect to clause (ii) of the definition thereof) over (b) the full amount required to be deposited or distributed, without duplication, pursuant to Sections 4.04(c), (d) or (e) on such
date. 
 SECTION 4.09 Reinstatement of Invested Amount. 

(a) The Invested Amount shall be reinstated on any Distribution Date by the amount of any Available Series Interest Collections that are
applied pursuant to Section 4.04(a)(vi), (vii), (viii) and (ix). This amount shall be applied as follows: 

(i) first, if the Class A Invested Amount has been reduced pursuant to Sections 4.05 or 4.06, to the

C Invested Amount until it equals the Class C Note Principal Balance minus the aggregate amount on deposit in the Note Distribution Account and the Note Defeasance Account (excluding, in each case, amounts representing Investment Proceeds) allocated
to it; then 
 (iv) fourth, if the Class D Invested Amount has been reduced pursuant to Sections 4.05 or 4.06,

Proceeds) allocated to it; and then 
 (v) fifth, if the Class E Invested Amount has been reduced pursuant to Sections
4.05 or 4.06, to the Class E Invested Amount until it equals the Required Class E Invested Amount.

 32 








 
cause each Eligible Investment to be delivered to it (including a securities intermediary) and shall be credited to the Note Distribution Account. Funds on deposit in the Note Distribution
Account shall be invested in Eligible Investments. On each Distribution Date, all Investment Proceeds on deposit in the Note Distribution Account shall be treated as Available Series Interest Collections with respect to the related Collection

entitlements, documents, certificates of deposit and other property from time to time on deposit in or credited to the Reserve Fund and in all interest, proceeds, earnings, income, revenue, dividends and other distributions thereof (including any
accrued discount realized on liquidation of any investment purchased at a discount) for the benefit of the Series 2015-3 Noteholders. Except as expressly provided in this Indenture Supplement and the Trust Sale and Servicing Agreement, the Servicer
agrees that it has no right of setoff or banker’s lien against, and no right to otherwise deduct from, any funds and other property held in the Reserve Fund for any amount owed to it by the Indenture Trustee, the Issuing Entity, any Noteholder

(including the Securities Intermediary) in Eligible Investments. All such Eligible Investments shall be held by the Indenture Trustee or its nominee for the benefit of the Series 2015-3 Noteholders. The Indenture Trustee shall cause each Eligible
Investment to be delivered to it or its nominee (including a securities intermediary) and shall be credited to the Reserve Fund. Funds on deposit in the Reserve Fund shall be invested in Eligible Investments. On each Distribution Date, all
Investment Proceeds on deposit in the Reserve Fund shall be treated as Available Series Interest Collections for such Distribution Date. The Indenture Trustee shall bear no responsibility or liability for any losses resulting from investment or
reinvestment of any funds in accordance with this Section 4.11(b) nor for the selection of Eligible Investments in accordance with the provisions of this Indenture Supplement, the Indenture or the Trust Sale and Servicing Agreement.

of the Reserve Fund Initial Amount. After the Closing Date, funds shall be deposited into the Reserve Fund as provided in Section 4.04(a)(x). The Depositor may at any time and from time to time make additional deposits into the Reserve
Fund; provided, however, the Depositor shall not be permitted to make any such discretionary deposit without satisfaction of the Series 2015-3 Rating Agency Condition with respect to each Class of Series 2015-3 Notes in connection
therewith if such deposit, together with any discretionary increases in the Subordination Factor and the Class E Invested Amount, would result in the aggregate amount of all such deposits and increases exceeding 5.0% of the Note Principal Balance as
of the date of such deposit. 
 (d) If on any Distribution Date, after giving effect to all withdrawals from and deposits to the Reserve
Fund, the amount on deposit in the Reserve Fund (excluding amounts representing Investment Proceeds) exceeds the Reserve Fund Required Amount then in effect, the Indenture Trustee shall, at the written direction of the Servicer, distribute such
excess to the Owner Trustee for distribution to the holders of the Certificate Interest in accordance with the Trust Agreement.

the Noteholders. The Indenture Trustee shall cause each Eligible Investment to be delivered to it (including a securities intermediary) and shall be credited to the Accumulation Period Reserve Account. Funds on deposit in the Accumulation Period

Account pursuant to Sections 4.04(a)(xi) and Section 4.04(b)(i) on such Distribution Date. If for any Distribution Date, the Accumulation Period Reserve Draw Amount is greater than zero, the Accumulation Period Reserve Draw
Amount, up to the Available Accumulation Period Reserve Account Amount, shall be withdrawn from the Accumulation Period Reserve Account on such Distribution Date by the Indenture Trustee (acting in accordance with the written instructions of the
Servicer) and deposited into the Collection Account for application as Available Series Interest Collections. 
 (d) If on any Distribution
Date, after giving effect to all withdrawals from and deposits to the Accumulation Period Reserve Account, the amount on deposit in the Accumulation Period Reserve Account exceeds the Accumulation Period Reserve Account Required Amount then in

 SECTION 4.14 Transfer Restrictions. 

(a) The Class E Notes (or interests therein) may not be acquired by or for the account of (i) a Benefit Plan other than an insurance
company general account (as defined in Prohibited Transaction Class Exemption (“PTCE”) 95-60) whose underlying assets include less than 25% “plan assets” and for which the purchase and
holding of the Class E Notes is eligible for and satisfied all conditions for relief under PTCE 95-60 or (ii) an employee benefit plan or plan that is not subject to the provisions of Title I of ERISA or
Section 4975 of the Code if such acquisition would result in a non-exempt prohibited transaction under, or a non-exempt violation of, any applicable law that is
substantially similar to Title I of ERISA or Section 4975 of the Code. By accepting and holding a Class E Note (or interest therein), the Holder thereof and any related Note Owner shall each be deemed to have represented and warranted that it
is not, nor is it acquiring the Note for the account of either, (i) a Benefit Plan other than an insurance company general account (as defined in Prohibited Transaction Class Exemption (“PTCE”)
95-60) whose underlying assets include less than 25% “plan assets” and for which the purchase and holding of the Class E Notes is eligible for and satisfied all conditions for relief under PTCE 95-60 or (ii) an employee benefit plan or plan that is not subject to the provisions of Title I of ERISA or Section 4975 of the Code if such acquisition would result in a
non-exempt prohibited transaction under, or a non-exempt violation of, any applicable law that is substantially similar to Title I of ERISA or Section 4975 of the
Code. By accepting and holding a Class A Note, Class B Note, Class C Note or Class D Note (or interest therein), the Holder thereof and any related Note Owner shall be deemed to have represented and warranted that either (i) it is not, nor
is it acquiring the Note for the account of, a Benefit Plan or any other plan that is subject to any law that is substantially similar to Title I of ERISA or Section 4975 of the Code or (ii) the acquisition and holding of the Note will not
give rise to a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a non-exempt violation of substantially similar law.
In addition, Benefit Plans may not acquire (i) a Class A Note, Class B Note, Class C Note, or Class D Note at any time that such Note would not be treated as indebtedness without substantial equity features, or (ii) a Class B Note,
Class C Note or Class D Note at any time that the ratings on such Note are below investment grade or the restrictions in Section 4.14(e) apply to such Note. By accepting and holding a Class A Note, Class B Note, Class C Note or
Class D Note (or interest therein), the Holder thereof and any related Note Owner shall each be deemed to have represented and warranted that its acquisition of such note is in compliance with the foregoing restriction. 

(b) The Series 2015-3 Private Notes will not be registered under the Securities Act or the securities or blue sky laws of any other
jurisdiction. Consequently, the Series 2015-3 Private Notes are not transferable other than pursuant to an exemption from the registration requirements of the Securities Act and satisfaction of certain other provisions specified herein. No sale,
pledge or other transfer of the Series 2015-3 Private Notes (or interest therein) may be made by any Person unless either (i) such sale, pledge or other transfer is made to or by the Depositor, (ii) so long as the Series 2015-3 Private
Notes are eligible for resale pursuant to Rule 144A under the Securities Act, such sale, pledge or other transfer is made to a person whom the transferor “reasonably believes” within the meaning of Rule 144A under the Securities Act is a


  
 36 








 
“qualified institutional buyer” within the meaning of Rule 144A under the Securities Act (a “Qualified Institutional Buyer”) acting for its own account (and not for the
account of others) or as a fiduciary or agent for others (which others also are Qualified Institutional Buyers) to whom notice is given that the sale, pledge or transfer is being made in reliance on Rule 144A under the Securities Act, or
(iii) such sale, pledge or other transfer is otherwise made in a transaction exempt from the registration requirements of the Securities Act, in which case (A) the Indenture Trustee shall require that both the prospective transferor and
the prospective transferee certify to the Indenture Trustee and the Depositor in writing the facts surrounding such transfer, which certification shall be in form and substance satisfactory to the Indenture Trustee and the Depositor, and
(B) the Indenture Trustee shall require a written opinion of counsel (which will not be at the expense of the Issuing Entity, the Seller, the Depositor, the Servicer or the Indenture Trustee) satisfactory to the Depositor and the Indenture
Trustee to the effect that such transfer will not violate the Securities Act. Neither the Depositor nor the Indenture Trustee shall be obligated to register the Series 2015-3 Private Notes under the Securities Act, qualify the Series 2015-3 Private
Notes under the securities laws of any state or provide registration rights to any purchaser or holder thereof. 
 (c) Transfer of a Class E
Note may only be made to a Person who is a United States Person (within the meaning of Section 7701(a)(30) of the Internal Revenue Code). Any Person acquiring a Class E Note or an interest therein (i) shall not be deemed to have made the
representations set forth in Section 2.14 of the Indenture and (ii) other than the Depositor shall not acquire or hold such Class E Note or interest therein in the form of a Book Entry Note. 

(d) No sale, pledge or other transfer may be made to any one person of a Class E Note with a face amount of less than the amount determined in
accordance with Section 1.01(E) hereof (in order to prevent the Issuing Entity from being treated as a “publicly traded partnership” under Section 7704 of the Code), and, in the case of any Person acting on behalf of one
or more third parties (other than a bank (as defined in Section 3(a)(2) of the Securities Act) acting in its fiduciary capacity), for a Class E Note with a face amount of less than such amount for each such third party. Any attempted transfer
in contravention of the immediately preceding restriction will be void ab initio and the purported transferor will continue to be treated as the owner of the Class E Notes for all purposes. No Class E Note may be transferred unless the
transferor provides to the Indenture Trustee an opinion of independent counsel that the transfer will not cause the Issuing Entity to be treated as an association (or publicly traded partnership) taxable as a corporation for federal income tax
purposes. 
 (e) (i) A sale, pledge, or transfer of a Class B Note, Class C Note or Class D Note may only be made to a Person who is a
United State Person (within the meaning of Section 7701(a)(30) of the Internal Revenue Code). A Person other than the Depositor acquiring a Class B Note, Class C Note or Class D Note or an interest therein shall be deemed to have made the
representations set forth in Section 2.14 of the Indenture; and (ii) no sale, pledge, or transfer of a Class B Note, Class C Note or Class D Note shall be made (x) to any one person with a face amount of less than 100% of the
Class B Note Principal Balance, Class C Note Principal Balance 

  
 37 








 
or Class D Note Principal Balance, as applicable, or (y) to a Special Pass-Through Entity, in each case, unless (A) an opinion of counsel
satisfactory to the Indenture Trustee and the Depositor that such sale, pledge, or transfer shall not cause the Issuing Entity to be treated as an association (or publicly traded partnership) taxable as a corporation for federal income tax purposes
shall have been delivered to the Indenture Trustee and the Depositor and (B) the Depositor shall have provided prior written approval; provided, however, that the restrictions in this Section 4.14(e) shall not apply in
the event counsel satisfactory to the Indenture Trustee and the Depositor has rendered an opinion to the effect that the Class B Note, Class C Note or Class D Note to be sold, pledged, or transferred will be characterized as indebtedness for federal
income tax purposes. Any attempted transfer in contravention of this Section 4.14(e) will be void ab initio and the purported transferor will continue to be treated as the owner of, as applicable, the Class B Note, Class C Note or
Class D Note for all purposes. 
 SECTION 4.15 Note Defeasance Account. 

(a) The Indenture Trustee, for the benefit of the Series 2015-3 Noteholders, shall establish and maintain in the name of the Indenture Trustee,
an Eligible Deposit Account (including any subaccounts thereof) bearing a designation clearly indicating that the funds and other property credited thereto are held for the benefit of the Series 2015-3 Noteholders (the “Note Defeasance
Account”). The Indenture Trustee shall possess all right, title and interest in all Eligible Investments and all monies, cash, instruments, securities, securities entitlements, documents, certificates of deposit and other property from time
to time on deposit in or credited to the Note Defeasance Account for the benefit of the Series 2015-3 Noteholders (other than Investment Proceeds, which shall be for the benefit of the Indenture Trustee). Except as expressly provided in this
Indenture Supplement, the Servicer agrees that it has no right of setoff or banker’s lien against, and no right to otherwise deduct from, any funds and other property held in the Note Defeasance Account for any amount owed to it by the
Indenture Trustee, the Issuing Entity, any Noteholder or any Series Enhancer. The Indenture Trustee, at the written direction of the Servicer, shall make deposits and withdrawals from the Note Defeasance Account from time to time, in the amounts and
for the purposes set forth in this Indenture Supplement. 
 (b) Funds on deposit in the Note Defeasance Account shall, at the direction or
election of the Indenture Trustee, be invested by the Indenture Trustee (including the Securities Intermediary) in Eligible Investments that mature prior to the next Distribution Date selected by the Indenture Trustee. All such Eligible Investments
shall be held by the Indenture Trustee or its nominee for the benefit of the Series 2015-3 Noteholders. The Indenture Trustee shall cause each Eligible Investment to be delivered to it (including a securities intermediary) and shall be credited to
the Note Defeasance Account. Notwithstanding anything to the contrary in the Indenture, the Indenture Trustee shall be entitled to receive all Investment Proceeds on the Note Defeasance Account when and as paid without any obligation to the Owner
Trustee, the Servicer or the Depositor in respect thereof. The Indenture Trustee will have no obligation to deposit any such amount in any account established hereunder or the Indenture. Notwithstanding Sections 6.1(f) and 8.3(f) of
the Indenture, the Indenture Trustee shall be liable for any investment losses with respect to funds on deposit in the Note Defeasance Account. 

  
 38 








 (c) All payments of amounts due and payable with respect to any Notes that are to be made from
amounts withdrawn from the Note Defeasance Account pursuant to this Indenture Supplement shall be made by the Indenture Trustee or by another Paying Agent from available funds on deposit in the Note Defeasance Account. 

(d) Upon the irrevocable deposit of any amount into the Note Defeasance Account pursuant to this Indenture Supplement, the Issuing Entity
shall have no further liability for, and shall be deemed to be discharged and released from its obligations with respect to, the Series 2015-3 Notes to the extent of the amount so deposited as such amounts are to be applied to the payments of
interest on and principal of the Series 2015-3 Notes in accordance with the priorities specified in this Indenture Supplement, and the Holders of the Series 2015-3 Notes shall have recourse and shall look solely to the Note Defeasance Account for
the payment of such amounts. 
 (e) All monies deposited with the Indenture Trustee in the Note Defeasance Account pursuant to this
Indenture Supplement shall be held in trust in a segregated trust account and (except for Investment Proceeds thereon) applied by the Indenture Trustee, in accordance with the provisions of the Series 2015-3 Notes and this Indenture Supplement, to
the payment, either directly or through any Paying Agent, as the Indenture Trustee may determine, to the Holders of Series 2015-3 Notes for payment on or redemption of the Series 2015-3 Notes, and no amounts so withdrawn from the Note Defeasance
Account for payments of Notes shall be paid over to the Issuing Entity. 
 (f) The Indenture Trustee may, at such time as there are no Notes
Outstanding, notify the Issuing Entity thereof in writing and withdraw and retain any funds then on deposit in the Note Defeasance Account. 

(g) Sections 8.3(f) and (g) of the Indenture shall not apply to the Note Defeasance Account. 

(h) The Note Defeasance Account shall constitute a “Note Distribution Account” solely for purposes of Sections 2.7,
3.1, 3.3(b), and 10.1 of the Indenture. 
 SECTION 4.16 FATCA. 

Each Noteholder or holder of an interest in a Note, by acceptance of such Note or such interest therein, agrees to provide to the Indenture
Trustee, any Paying Agent or the Issuing Entity, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the Noteholder FATCA Information. In addition, each Noteholder or holder of an
interest in a Note, by acceptance of such Note or such interest therein, agrees that the Indenture Trustee has the right to withhold any amounts of interest (properly withholdable under law and without any corresponding gross-up) payable to a
Noteholder or holder of an interest in a Note that fails to comply with the requirements of the preceding sentence.

in this Section 6.02), which failure materially and adversely affects the rights of the Noteholders, and such default shall continue or not be cured for a period of 30 days after there shall have been given, by registered or certified
mail, to the Issuing Entity and the Servicer by the Indenture 

  
 45 








 
Trustee or to the Issuing Entity, the Servicer and the Indenture Trustee by the Holders of at least 25% of the Outstanding Amount of the Series 2015-3 Notes, a written notice specifying such

in the form of an Officer’s Certificate of any event which with the giving of notice and the lapse of time would become an Event of Default under Section 6.02(d), its status and what action the Issuing Entity is taking or proposes
to take with respect thereto. 
 SECTION 6.03 Acceleration of Maturity; Rescission and Annulment. 

(a) If an Event of Default, other than an Event of Default as a result of an Insolvency Event with respect to the Issuing Entity, should occur
and is continuing, then the Indenture Trustee may, or shall, at the direction of the Holders of at least a majority of the Outstanding Amount of the Series 2015-3 Notes, declare all the Series 2015-3 Notes to be immediately due and payable, by a
notice in writing to the Issuing Entity and the Servicer (and to the Indenture Trustee if declared by such Noteholders) setting forth the Event or Events of Default. If an Insolvency Event of Default occurs and is continuing, then the Series 2015-3
Notes shall be immediately and without further action become due and payable, and the Indenture Trustee shall give a notice to such effect in writing to the Issuing Entity (although failure to give such notice shall not affect the immediate
acceleration of maturity). Upon any such declaration or automatic occurrence, the Revolving Period or the Controlled Accumulation Period, as applicable, with respect to the Series 2015-3 Notes shall terminate, an Early Amortization Period shall
commence and the unpaid principal amount of such Series 2015-3 Notes, together with accrued and unpaid interest thereon through the date of acceleration, shall become immediately due and payable. 

  
 46 








 (b) At any time after such acceleration of maturity has occurred pursuant to
Section 6.03(a) and before a judgment or decree for payment of the money due has been obtained by the Indenture Trustee as provided in Article V of the Indenture, the Holders of at least a majority of the Outstanding Amount of the
Series 2015-3 Notes, by written notice to the Issuing Entity, the Servicer and the Indenture Trustee, may rescind and annul such acceleration and its consequences with respect to the Series 2015-3 Notes. No such rescission and annulment shall extend
to or affect any subsequent Event of Default or impair any right consequent thereto; and provided, further, that if the Indenture Trustee shall have proceeded to enforce any right under the Indenture and such proceedings shall have
been discontinued or abandoned because of such rescission and annulment or for any other reason, or shall have been determined adversely to the Indenture Trustee, then and in every such case, the Indenture Trustee, the Issuing Entity and the
Noteholders, as the case may be, shall be restored to their respective former positions and rights hereunder and under the Indenture, and all rights, remedies and powers of the Indenture Trustee, the Issuing Entity and the Noteholders, as the case
may be, shall continue as though no such proceedings had been commenced. 
 (c) If the Series 2015-3 Notes shall have been accelerated
following an Event of Default, the Indenture Trustee may exercise the remedies available to it as set forth in Article V the Indenture. 

(d) Any money or property collected by the Indenture Trustee pursuant to this Section 6.03 following the acceleration of the
maturities of the Series 2015-3 Notes (so long as such acceleration has not been rescinded or annulled) shall be paid out or allocated in accordance with Section 5.4(b) of the Indenture. 

ARTICLE VII 
 REDEMPTION
OF SERIES 2015-3 NOTES; SERIES LEGAL MATURITY; FINAL 
 DISTRIBUTIONS 

SECTION 7.01 Optional Redemption of Series 2015-3 Notes. 

(a) On any day occurring on or after the date on which the Note Principal Balance is reduced to 10% or less of the Initial Note Principal
Balance, the Servicer (if Ally Financial or an Affiliate of Ally Financial is the Servicer) shall have the option to purchase the Series 2015-3 Noteholders’ Collateral and thereby cause a redemption of the Series 2015-3 Notes, at a purchase
price equal to (i) if such day is a Distribution Date, the Reassignment Amount for such Distribution Date or (ii) if such day is not a Distribution Date, the Reassignment Amount for the Distribution Date following such day. 

(b) Upon any such election, the Servicer shall give the Depositor, the Indenture Trustee, the Issuing Entity and, if applicable, other holders
of the Certificate Interest at least 30 days prior written notice of the date on which the Servicer intends to exercise such optional redemption as well as the Reassignment Amount and the Indenture Trustee shall provide notice to Holders of the
Series 2015-3 Notes that it has received such notice from the Servicer. No later 

  
 47 








 
than 11:00 a.m. (New York City time) on such day the Servicer shall deposit the Reassignment Amount into the Collection Account or, at the direction of the Depositor or election of the Servicer
in an amount not to exceed the interest and principal to be paid with respect to the Series 2015-3 Notes, the Note Defeasance Account, in immediately available funds. Such redemption option is subject to payment in full of the Reassignment Amount.
Following such deposit into the Collection Amount or the Note Defeasance Account, as applicable, in accordance with the foregoing, the Invested Amount of the Series 2015-3 Notes shall be deemed reduced to zero and the Series 2015-3 Noteholders shall
be deemed to have no further interest in the Receivables. The Reassignment Amount shall be distributed as set forth in Section 7.02. 

SECTION 7.02 Series Legal Maturity.

Servicing Agreement. With respect to the Reassignment Amount deposited into the Collection Account or the Note Defeasance Account, as applicable, pursuant to Section 2.5 of the Trust Sale and Servicing Agreement or pursuant to
Section 7.01 of this Indenture Supplement or the proceeds from any Foreclosure Remedy pursuant to Section 5.4 of the Indenture, the Indenture Trustee shall, in accordance with the written direction of the Servicer, no later
than 11:00 a.m. (New York City time) on the related Distribution Date, make deposits or distributions of the following amounts (in the priority set forth below and, in each case after giving effect to any deposits and distributions otherwise to be
made on such date) in immediately available funds first, from amounts on deposit in the Note Defeasance Account and, to the extent the amounts on deposit in the Note Defeasance Account are insufficient to make such allocations, second, from
available funds on deposit in the Collection Account, to make the following distributions or deposits in the following priority: 

(i) (A) the Class A Note Principal Balance on such Distribution Date shall be distributed to the Indenture Trustee for
payment to the Class A Noteholders and (B) an amount equal to the sum of (1) the Class A Monthly Interest for such Distribution Date and (2) any Class A Monthly Interest previously due but not paid to the Class A
Noteholders on prior Distribution Dates, shall be distributed to the Indenture Trustee for payment to the Class A Noteholders on such Distribution Date; 

(ii) (A) the Class B Note Principal Balance on such Distribution Date shall be distributed to the Indenture Trustee for payment
to the Class B Noteholders and (B) an amount equal to the sum of (1) the Class B Monthly Interest for such Distribution Date and (2) any Class B Monthly Interest previously due but not paid to the Class B Noteholders on prior

(iii) (A) the Class C Note Principal Balance on such Distribution Date shall be


  
 48

(2) any Class C Monthly Interest previously due but not paid to the Class C Noteholders on prior Distribution Dates, shall be distributed to the Indenture Trustee for payment to the Class C Noteholders on such Distribution Date; 

(iv) (A) the Class D Note Principal Balance on such Distribution Date shall be distributed to the Indenture Trustee for payment

Distribution Dates, shall be distributed to the Indenture Trustee for payment to the Class D Noteholders on such Distribution Date; and 

(v) the Class E Note Principal Balance on such Distribution Date shall be distributed to the Indenture Trustee for payment to
the Class E Noteholders on such Distribution Date. 
 (b) Notwithstanding anything to the contrary in this Indenture Supplement, the
Indenture or the Trust Sale and Servicing Agreement, (i) all amounts distributed to the Indenture Trustee pursuant to Section 7.02(a) for payment to the Series 2015-3 Noteholders shall be deemed distributed in full to the Series
2015-3 Noteholders on the date on which such funds are distributed to the Indenture Trustee pursuant to this Section and shall be deemed to be a final distribution pursuant to Section 11.2 of the Indenture and (ii) in the event that
the amounts available for final distribution to the Series 2015-3 Noteholders and to the Noteholders of any other Series on any Distribution Date are less than the full amount required to be so distributed, the available amounts shall be allocated
to each Series based on the respective amounts required to be distributed to each such Series (including Series 2015-3) on such Distribution Date.

 EXHIBIT A 

FORM OF CLASS [A][B][C][D][E] NOTE 

[Unless this Class A Note is presented by an authorized representative of The Depository Trust Company, a New York corporation
(“DTC”), to the Issuing Entity or its agent for registration of transfer, exchange or payment, and any Note issued is registered in the name of Cede & Co. or in such other name as is requested by an authorized
representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC) ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
inasmuch as the registered owner hereof, Cede & Co., has an interest herein.] 
 [This Class [B][C][D][E] Note has not and will not
be registered under the United States Securities Act of 1933, as amended (the “Securities Act”), or under the securities or blue sky laws of any State in the United States or any foreign securities laws. By its acceptance of this
Class [B][C][D][E] Note (or interest therein), the Holder of this Class [B][C][D][E] Note (or such interest), if other than the Depositor, is deemed to represent and warrant to the Depositor and the Indenture Trustee that it is a “Qualified
Institutional Buyer” as defined in Rule 144A under the Securities Act and is acquiring this Class [B][C][D][E] Note (or interest therein) for its own account (and not for the account of others) or as a fiduciary or agent for others (which
others also are Qualified Institutional Buyers) or has otherwise acquired an interest in the Class [B][C][D][E] Note in a transaction that is exempt from the registration requirements of the Securities Act.] 

[No sale, pledge or other transfer of this Class [B][C][D][E] Note (or interest therein) may be made by any Person unless either (i) such
sale, pledge or other transfer is made by or to the Depositor, (ii) at the time of such sale, pledge or other transfer, (A) this Class [B][C][D][E] Note is eligible for resale pursuant to Rule 144A under the Securities Act, and such sale,
pledge or other transfer is made to a person whom the transferor “reasonably believes” within the meaning of Rule 144A under the Securities Act is a “qualified institutional buyer” within the meaning of Rule 144A under the
Securities Act (a “Qualified Institutional Buyer”) acting for its own account or the accounts of other Qualified Institutional Buyers, and (B) the transferee is aware that the transferor of this Class [B][C][D][E] Note intends
to rely on the exemption from the registration requirements of the Securities Act provided by Rule 144A under the Securities Act, or (iii) such sale, pledge or other transfer is otherwise made in a transaction exempt from the registration
requirements of the Securities Act, in which case (A) the Indenture Trustee shall require that both the prospective transferor and the prospective transferee certify to the Indenture Trustee and the Depositor in writing the facts surrounding
such transfer, which certification shall be in form and substance satisfactory to the Indenture Trustee and the Depositor, and (B) the Indenture Trustee shall require a written opinion of 

  
 Ex. A-1 








 
counsel (which will not be at the expense of the Seller, the Depositor, the Administrator, the Issuing Entity, the Servicer or the Indenture Trustee) satisfactory to the Depositor and the
Indenture Trustee to the effect that such transfer will not violate the Securities Act and satisfaction of certain other provisions specified herein.] 

Each Noteholder or Note Owner, by acceptance of this Note (or interest therein), hereby covenant and agree that by accepting the benefits of
the Indenture such Noteholder or Note Owner shall not, prior to the date which is one year and one day after the termination of the Indenture with respect to the Issuing Entity and, with respect to the Depositor, the Securities issued by each other
trust formed by and each other financing by the Depositor, acquiesce, petition or otherwise invoke or cause the Depositor or the Issuing Entity to invoke the process of any court or government authority for the purpose of commencing or sustaining a
case against the Depositor or the Issuing Entity under any Insolvency Law or appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or other similar official of the Depositor or the Issuing Entity or any substantial part of
the property of either of them, or ordering the winding up or liquidation of the affairs of the Depositor or the Issuing Entity. 
 Each
Noteholder, by acceptance of this Note (or interest therein), covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuing Entity, the Owner Trustee or the Indenture Trustee on the Notes
or under the Indenture or any certificate or other writing delivered in connection herewith or therewith, against: 
 (i) the
Indenture Trustee or the Owner Trustee in its individual capacity; 
 (ii) the Depositor or any other owner of a beneficial
interest in the Issuing Entity; or 
 (iii) any partner, owner, beneficiary, agent, officer, director or employee of the
Indenture Trustee or the Owner Trustee in its individual capacity, any holder of a beneficial interest in the Issuing Entity, the Owner Trustee or the Indenture Trustee or of any successor or assign of the Indenture Trustee or the Owner Trustee in
its individual capacity, except as any such Person may have expressly agreed (it being understood that the Indenture Trustee and the Owner Trustee have no such obligations in their individual capacity) and except that any such partner, owner or
beneficiary shall be fully liable, to the extent provided by applicable law, for any unpaid consideration for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. 

Except as expressly provided in the Basic Documents, none of the Seller, the Depositor, the Servicer, the Indenture Trustee nor the Owner
Trustee in their respective individual capacities, any owner of a beneficial interest in the Issuing Entity, nor any of 

  
 Ex. A-2 








 
their respective partners, owners, beneficiaries, agents, officers, directors, employees or successors or assigns, shall be personally liable for, nor shall recourse be had to any of them for,
the payment of principal of [or interest on], or performance of, or omission to perform, any of the covenants, obligations or indemnifications contained in this Note or the Indenture, it being expressly understood that said covenants, obligations
and indemnifications have been made solely by the Issuing Entity. Each Noteholder by accepting this Note (or any interest therein) acknowledges that such Noteholder’s Note (or interest therein) represents beneficial interests in the Issuing
Entity only and does not represent interests in or obligations of the Depositor, the Servicer, the Administrator, the Owner Trustee, the Indenture Trustee or any Affiliate thereof (other than the Issuing Entity) and no recourse, either directly or
indirectly, may be had against such parties or their assets, except as may be expressly set forth or contemplated in the Basic Documents. Each Noteholder by the acceptance of a Note (or beneficial interest therein) agrees that except as expressly
provided in the Basic Documents, in the event of nonpayment of any amounts with respect to the Notes, it shall have no claim against any of Depositor, the Servicer, the Administrator, the Owner Trustee, the Indenture Trustee or any Affiliate for any
deficiency, loss or claim therefrom; provided, however, that nothing contained herein shall be taken to prevent recourse to, and enforcement against, the assets of the Issuing Entity for any and all liabilities, obligations and
undertakings contained in the Indenture or in the Notes. 
 If any of the foregoing covenants of a Noteholder is prohibited by, or declared
illegal or otherwise unenforceable against or with respect to any Noteholder under applicable law by any court or other authority of competent jurisdiction, and, as a result, a Noteholder is deemed to have an interest in any assets of the Depositor
or any Affiliate of the Depositor other than the Issuing Entity (“other assets”), each Noteholder or Note Owner by the acceptance of this Note (or beneficial interest therein), 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 meaning of, and subject to, Section 510(a) of the Bankruptcy Code. 

[The holder of this Note, by acceptance of this Note, and each holder of a beneficial interest therein, unless otherwise required by the
appropriate taxing authorities, agree to treat this Note as indebtedness of the Issuing Entity for applicable United States federal, state and local income and franchise tax purposes and any other taxes imposed upon, measured by or based upon gross
or net income.] 
 [[Include if restrictions in Section 4.14(e) apply.] Any holder of this Class [B][C][D] Note, by its acceptance of
this Class [B][C][D] Note, shall be deemed to have represented that (a) it is not (i) an employee benefit plan (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”))
that is 

  
 Ex. A-3 








 
subject to the provisions of Title I of ERISA, (ii) a plan described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended (the “Code”) which is
subject to Section 4975 of the Code or (iii) an entity whose underlying assets include plan assets by reason of an employee benefit plan’s or plan’s investment in such entity (each of the foregoing, a “Benefit

give reise to a non-exempt violation of such substantially similar law.] [[Include if restrictions in Section 4.14(e) do not apply.] Any holder of this Class [A][B][C][D] Note, by its acceptance of this Class [A][B][C][D] Note, shall be deemed

any substantially similar applicable law. Employee benefit plans subject to the provisions of Title I of ERISA, plans subject to Section 4975 of the Code and entities whose underlying assets include plan assets by reason of an employee benefit
plan’s or plan’s investment in such entity may not acquire this Class [A][B][C][D] Note at any time that this Class [A][B][C][D] Note would not be treated as indebtedness without substantial equity features [or the ratings on this Class
[B][C][D] Note are below investment grade]. 
 [Any holder of this Class [E] Note, by its acceptance of this Class [E] Note, shall be deemed

SERIES 2015-3 [FIXED RATE ASSET BACKED][ASSET BACKED EQUITY] NOTE, CLASS [A][B][C][D][E] 

Summary of Terms and Conditions 

This Note is one of a duly authorized issue of Notes of the Issuing Entity, designated as the Series 2015-3 [Fixed Rate] Asset Backed Notes
(the “Notes”), issued under the Indenture, dated as of February 12, 2010 (the “Indenture”), between the Issuing Entity and Wells Fargo Bank, National Association, as indenture trustee (the “Indenture
Trustee”), as supplemented by the Series 2015-3 Indenture Supplement, dated as of June 3, 2015 (the “Indenture Supplement” and, together with the Indenture, the “Series Agreement”), and representing
the right to receive certain payments from the Issuing Entity. The Notes are subject to all of the terms of the Series Agreement. All terms used in this Note that are defined in the Series Agreement have the meanings assigned to them in or pursuant
to the Series Agreement. In the event of any conflict or inconsistency between the Series Agreement and this Note, the Series Agreement controls. 

The [Class A Notes, the Class B Notes, the Class C Notes, the Class D Notes and the Class E Note] with initial principal amounts of
$[            ], $[            ], $[            ],
$[            ] and $[            ], respectively, shall also be issued under the Series Agreement. [The rights of the holders of
the [Class A Notes, the Class B Notes, the Class C Notes, and the Class D Notes] to receive payments on [the Class A Notes, the Class B Notes, the Class C Notes and the Class D Notes] are senior to the rights of the holders of the Class
[B][C][D][E] Notes to receive payments as specified in the Series Agreement.] [The rights of the holders of [the Class B Notes, the Class C Notes, the Class D Notes, and the Class E Notes] to receive payments on [the Class B Notes, the Class C
Notes, the Class D Notes and the Class E Notes] are subordinate to the rights of the holders of the Class [A][B][C][D] Notes to receive payments as specified in the Series Agreement.] 

The Series 2015-3 Notes only represent interest in the Issuing Entity allocated to the Series 2015-3 Notes. The Noteholder, by its acceptance
of this Note, agrees that it shall look solely to the property of the Issuing Entity allocated to the payment of the Notes for payment hereunder and under the Series Agreement and that the Indenture Trustee is not liable to the Noteholders for any
amount payable under the Notes or the Series Agreement or, except as expressly provided in the Series Agreement, subject to any liability under the Series Agreement. 

Upon the irrevocable deposit of any amount into the Note Defeasance Account pursuant to the Series Agreement, the Issuing Entity shall have no
further liability for, and shall be deemed to be discharged and released from its obligations with respect to, this Note to the extent of the amount so deposited as such amounts are to be applied to the payments of interest on and principal of this
Note in accordance with the priorities specified in the Series Agreement, and the Noteholder shall have recourse and shall look solely to the Note Defeasance Account for the payment of such amounts. 

  
 Ex. A-8 








 Each Noteholder or holder of an interest in a Note, by acceptance of such Note or such interest
therein, agrees to provide to the Indenture Trustee, any Paying Agent or the Issuing Entity, upon its request, the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the Noteholder FATCA Information. In
addition, each Noteholder or holder of an interest in a Note, by acceptance of such Note or such interest therein, agrees that the Indenture Trustee has the right to withhold any amounts of interest (properly withholdable under law and without any
corresponding gross-up) payable to a Noteholder or holder of an interest in a Note that fails to comply with the requirements of the preceding sentence. 

This Note does not purport to summarize the Series Agreement and reference is made to the Series Agreement for the interests, rights and
limitations of rights, benefits, obligations and duties evidenced thereby, and the rights, duties and immunities of the Indenture Trustee. 

The Class [A][B][C][D][E] Note Initial Principal Balance is $[            ]. The
Class [A][B][C][D][E] Note Principal Balance on any date of determination shall be an amount equal to the Class [A][B][C][D][E] Note Initial Principal Balance minus the aggregate amount of any principal payments made to the Class [A][B][C][D][E]
Noteholders before such date. 
 The Series 2015-3 Expected Maturity Date is the May 2018 Distribution Date, but principal with respect to
the Class [A][B][C][D][E] Notes may be paid earlier or later under certain circumstances described in the Series Agreement. If for one or more months during the Controlled Accumulation Period there are not sufficient funds to deposit the Controlled
Deposit Amount into the Note Distribution Account or, to the extent permitted by the Indenture Supplement, the Note Defeasance Account, then to the extent that excess funds are not available on subsequent Distribution Dates with respect to the
Controlled Accumulation Period to make up for such shortfalls, the final payment of principal of the Notes shall occur later than the Series 2015-3 Expected Maturity Date. Payments of principal of the Notes shall be payable in accordance with the
provisions of the Series Agreement. 
 Subject to the terms and conditions of the Series Agreement, the Depositor may, from time to time,
direct the Owner Trustee, on behalf of the Issuing Entity, to issue one or more new Series of notes. 
 On each Distribution Date, the
Indenture Trustee shall distribute to each Class [A][B][C][D][E] Noteholder of record on the related Record Date (except for the final distribution in respect of this Note) such Class [A][B][C][D][E] Noteholder’s pro rata share of the amounts
held by the Indenture Trustee that are allocated and available on

such Distribution Date to pay [interest and] principal on the Class [A][B][C][D][E] Notes pursuant to the Indenture Supplement. Except as provided in the Series Agreement with respect to a final
distribution, distributions to the Noteholders shall be made by (a) wire transfer (to the account specified by the applicable Noteholder) or check mailed to the applicable Noteholder (at such Noteholder’s address as it appears in the Note
Register), except that with respect to any Notes registered in the name of the nominee of a Clearing Agency, such distribution shall be made in immediately available funds and (b) without presentation or surrender of any Note or the making of
any notation thereon. Final payment of this Note shall be made only upon presentation and surrender of this Note at the office or agency specified in the notice of final distribution delivered by the Indenture Trustee to the Noteholders in
accordance with the Series Agreement. 
 On any day occurring on or after the date on which the Note Principal Balance is reduced to 10% or
less of the Initial Note Principal Balance, the Servicer (if Ally Financial or an Affiliate of Ally Financial is the Servicer) shall have the option to redeem the Notes, at a purchase price equal to (a) if such day is a Distribution Date, the
Reassignment Amount for such Distribution Date or (b) if such day is not a Distribution Date, the Reassignment Amount for the Distribution Date following such day. 

This Note does not represent an obligation of, or an interest in, Ally Bank, Ally Financial, Inc., Ally Wholesale Enterprises LLC, the
Indenture Trustee, the Owner Trustee or any Affiliate of any of them (other than the Issuing Entity) and is not insured or guaranteed by any governmental agency or instrumentality. 

The Issuing Entity is permitted by the Indenture, under certain circumstances, to merge or consolidate subject to the rights of the Indenture
Trustee and the Noteholders. 
 [Except as otherwise provided in the Indenture Supplement, the Class [A][B][C][D] Notes are issuable only in
minimum denominations of $1,000 and integral multiples of $1,000.][Except as otherwise provided in the Indenture Supplement, the Class E Notes are issuable only in a minimum denomination of 100% of the Class E Note Principal Balance] The transfer of
this Note shall be registered in the Note Register upon surrender of this Note for registration of transfer at any office or agency maintained by the Transfer Agent and Registrar accompanied by a written instrument of transfer, in a form
satisfactory to the Indenture Trustee or the Transfer Agent and Registrar, duly executed by the Noteholder or such Noteholder’s attorney, and duly authorized in writing with such signature guaranteed, and thereupon one or more new Class
[A][B][C][D][E] Notes in any authorized denominations of like aggregate principal amount shall be issued to the designated transferee or transferees. 

As provided in the Series Agreement and subject to certain limitations therein set forth, Class [A][B][C][D][E] Notes are exchangeable for new
Class [A][B][C][D][E] Notes in any authorized denominations and of like aggregate principal amount, upon surrender of such Notes to be exchanged at the office or agency of the Transfer Agent

of the Issuing Entity, the Depositor or the Indenture Trustee shall treat the person in whose name this Note is registered as the owner hereof for all purposes, and none of the Issuing Entity, the Depositor, the Indenture Trustee or any agent of the
