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

ARTICLE I 
 CREATION OF
SERIES 2018-2 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 2018-2 Asset Backed Notes” or the “Series 2018-2 Notes.” The Series 2018-2 Notes shall be issued in five Classes, the first shall be known as the “Series 2018-2 Fixed Rate Asset Backed Notes, Class A,” the
second shall be known as the “Series 2018-2 Fixed Rate Asset Backed Notes, Class B,” the third shall be known as the “Series
2018-2 Fixed Rate Asset Backed Notes, Class C,” the fourth shall be known as the “Series 2018-2 Fixed Rate Asset Backed Notes,
Class D,” and the fifth shall be known as the “Series 2018-2 Asset Backed Equity Notes, Class E.” The Series
2018-2 Notes shall be due and payable on the Series 2018-2 Legal Maturity Date. 

(b) Series 2018-2 shall be a Nonoverconcentration Series. Series
2018-2 shall be in Excess Interest Sharing Group One and in Principal Sharing Group One. Series 2018-2 shall not be a Shared Enhancement Series or in an Interest
Reallocation Group. Series 2018-2 shall not be subordinated to any other Series. 
 (c) The Series 2018-2 Notes are “Notes” and this Indenture Supplement is an “Indenture Supplement” for all purposes under the Indenture. If any provision of the Series
2018-2 Notes or this Indenture Supplement conflicts with or is inconsistent with any provision of the Indenture, the provisions of the Series 2018-2 Notes or this
Indenture Supplement, as the case may be, shall control. 
 (d) Each term defined in Section 2.01 of this Indenture
Supplement relates only to Series 2018-2 and this Indenture Supplement and to no other Series or Indenture Supplements. 

(e) Notwithstanding anything to the contrary in the Indenture, the Series 2018-2 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 2018-2 Notes, other than the Class E Note, 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 2018-2 Notes, create and issue additional Series 2018-2 Notes equal in rank to any Class or Tranche of Series 2018-2 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 2018-2
Notes in a Class or Tranche of Series 2018-2 Notes or except for the first payment of interest following the Issuance Date of such additional Series 2018-2 Notes in
a Class or Tranche of Series 2018-2 Notes. This is called a “reopening.” A reopening shall only occur if either (a) such additional Series
2018-2 Notes will, for U.S. federal income tax purposes, have the same issue price and issue date as do any other Series 2018-2 Notes (of the same applicable
Class or Tranche) that are Outstanding at that time, or (b) such additional Series 2018-2 Notes will have a CUSIP different from that of any other Series
2018-2 Notes (of the same applicable Class or Tranche) that are Outstanding at that time. When issued, the additional Series 2018-2 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 2018-2 Notes with the other Outstanding Notes of that Class or Tranche
without preference, priority or distinction. These additional Series 2018-2 Notes may be consolidated and form a single Class or Tranche with the previously issued Series
2018-2 Notes and shall have the same terms as to status, redemption or otherwise as the previously issued Series 2018-2 Notes.

 (g) On the
first Business Day of the earlier to occur of the Controlled Accumulation Period and the Early Amortization Period, the Indenture Trustee, acting in accordance with written instructions from the Servicer, shall withdraw from the Excess Funding
Account and apply in accordance with Sections 4.04(d) or (e), as applicable, an amount equal to the lesser of (i) the Series 2018-2 Excess Funding Amount for such date and (ii) the
amount required to be deposited or distributed on that date pursuant to Section 4.04(d)(i) or 4.04(e)(i), as applicable that was not previously deposited or distributed on that date. 

(h) The Controlled Accumulation Period is scheduled to commence on the first day of the November 2020 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 2018-2 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 2020 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 to or greater than the Required Accumulation Factor Number; provided, however, that the Accumulation Period Length shall not be determined to be less than one Collection Period. If the
number of whole Collection Periods remaining after such Determination Date and before the Series 2018-2 Expected Maturity Date is less than or equal to the Accumulation Period Length calculated as of such
Determination Date, the Controlled Accumulation Period shall commence on the first day of the following Collection Period; provided, however, if such number of Collection Periods is greater than such Accumulation Period Length, the
commencement of the Controlled Accumulation Period shall be delayed until at least the next Determination Date, at which time the Accumulation Period Length shall be recalculated as described above. 

(i) All distributions that are deposited by the Indenture Trustee into the Certificate Distribution Account for distribution to the holders of
the Certificate pursuant to this Indenture Supplement shall be made in accordance with such written remittance instructions as may be provided to the Indenture Trustee by the Depositor from time to time. 

  
 26 








 (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. 
 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: 

  
 27 








 (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 
 (v) fifth, the Class A Invested Amount shall be reduced by
any remaining amount until the Class A Invested Amount is reduced to zero. 
 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 in the distributions required under clauses (ii) through (v) of Section 4.04(a)), and (iv) fourth, amounts on deposit in the Note Distribution Account for the payment of
principal (first for the Class E Notes, then for the Class D Notes, then for the Class C Notes, then for the 

  
 28 








 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 to zero; then 
 (d) 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 
 (e) fifth, the
Class A Invested Amount shall be reduced by any remaining amount until the Class A Invested Amount is reduced to zero.

 Subject to Section 8.05(b) of the Indenture, Excess Interest
Collections with respect to the Excess Interest Sharing Series in Excess Interest Sharing Group One for any Distribution Date shall be allocated to Series 2018-2 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 2018-2 for such Distribution Date and the 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 2018-2 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 (xi) 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 2018-2 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 be distributed, without duplication, pursuant to clauses (i) through (xi)
of Section 4.04(a) on such Distribution Date. 
 SECTION 4.08 Shared Principal Collections. 

Subject to Section 8.5(c) of the Indenture, the aggregate amount of Shared Principal Collections with respect to the
Principal Sharing Series in Principal Sharing Group One for any 

  
 29 








 date shall be allocated to Series 2018-2 in an amount equal to the
product of (i) the aggregate amount of Shared Principal Collections, times (ii) a fraction, the numerator of which is the Principal Shortfall for Series 2018-2 for such date and the
denominator of which is the aggregate amount of Principal Shortfalls for all the Principal Sharing Series in Principal Sharing Group One for such date. The “Principal Shortfall” for Series
2018-2 shall equal (a) for any date in the Revolving Period, zero, (b) for any date in the Controlled Accumulation Period, the amount to be deposited or distributed pursuant to Sections
4.04(d) over 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 2018-2 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
Class A Invested Amount until it equals the Class A 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 
 (ii) second, if the Class B Invested Amount has been reduced pursuant to Sections
4.05 or 4.06, to the Class B Invested Amount until it equals the Class B Note Principal Balance minus the aggregate amount on deposit in the Note Distribution Account and the Note Defeasance Account (excluding amounts
representing Investment Proceeds) allocated to it; then 
 (iii) third, if the Class C Invested Amount has been reduced
pursuant to Sections 4.05 or 4.06, to the Class 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, to the Class D Invested Amount until it equals the Class D 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; and then 

  
 30 








 (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. 

SECTION 4.10 Note Distribution Account. 

(a) The Servicer, for the benefit of the Noteholders, shall establish and maintain with the Indenture Trustee in the name of the Indenture
Trustee, on behalf of the Issuing Entity, 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 Noteholders (the
“Note Distribution 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

Available Series Interest Collections with respect to the related Collection Period. The Indenture Trustee shall bear no responsibility or liability for any losses resulting from investment or reinvestment of any funds in accordance with this

(c) The Series 2018-2 Private Notes will not be registered under the Securities Act or the securities
or blue sky laws of any other jurisdiction. Consequently, the Series 2018-2 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 2018-2 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 2018-2 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 “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 2018-2 Private Notes under the Securities Act, qualify the Series 2018-2 Private Notes under the securities laws of any state or provide registration rights to any purchaser
or holder thereof. 

  
 34 








 (d) 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. 

(e) 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. The transferee, or, if different, the beneficial owner of such Class E Note, covenants that it will provide to any subsequent transferee a properly completed IRS Form W-9 signed under penalty of perjury, or other appropriate certification pursuant to Section 1446(f) of the Code (and to the extent future Treasury regulations or guidance relating to Section 1446(f) of the
Code require other documentation, it will provide such other documentation). 
 (f) (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 States 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 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(f) 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. If any Class B Note, Class C
Note or Class D Note held by the transferee is required to be treated other than as indebtedness for federal income tax purposes, then the transferee, or, if different, the beneficial owner of such Class B Note, Class C Note or
Class D Note, covenants that it will provide to any subsequent transferee a properly completed IRS Form W-9 signed under penalty of perjury, or other appropriate certification pursuant to
Section 1446(f) of the Code (and to the extent future Treasury regulations or guidance relating to Section 1446(f) of the Code require other documentation, it will provide such other documentation). Any attempted transfer in contravention
of this Section 4.14(f) will be 

  
 35 








 
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.

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 2018-2 Noteholders (other

benefit of the Series 2018-2 Noteholders. The Indenture Trustee shall cause each Eligible Investment to be delivered to it (including the Securities Intermediary) and shall be credited to 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 2018-2 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 2018-2 Notes in accordance with the priorities specified in this Indenture Supplement, and the Holders of the Series 2018-2 Notes shall have recourse and shall look solely to the Note Defeasance Account for the payment of such amounts. 

  
 36 








 (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

2018-2 Notes for payment on or redemption of the Series 2018-2 Notes, and no amounts so withdrawn from the Note Defeasance Account for payments of Notes shall be paid
over to the Issuing Entity.

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.

2018-2 Note Owners shall be permitted to vote for at least 150 days after such filing.

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.

to the Class E Noteholders on such Distribution Date.

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 2018-2 Noteholders
shall be deemed distributed in full to the Series 2018-2 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 2018-2 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

 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 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 

  
 Ex. A-1 








 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 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 

  
 Ex. A-2 








 
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.] 
 [Any holder of this Class [A][B][C][D] Note, by its acceptance of this Class [A][B][C][D] Note, shall be deemed to have
represented that either (a) it is not, nor is it acquiring or holding the Class [A][B][C][D] Note with the assets of (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 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, (iii) an entity whose underlying assets are deemed to include “plan assets” of such an employee benefit plan or a plan (each of clause (i) through (iii), a “Benefit Plan”) or
(iv) 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 (b) the acquisition and holding of the Class [A][B][C][D] Note will not give rise to a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a violation of any substantially similar applicable law. Benefit Plans may not acquire this Class [A][B][C][D]
Note at any time that this Class [A][B][C][D] Note is rated below investment grade.] [Any holder of this Class [E] Note, by its acceptance of this Class [E] Note, shall be deemed to have represented that (a) it is either (1) not acquiring
or holding the Class [E] Note with the plan assets of (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 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, (iii) an entity whose underlying assets
are deemed to include “plan assets” of such an employee benefit plan or a plan (each of clause (i) through (iii), a “Benefit Plan”) or (2) it is an insurance company general account (as defined in Prohibited
Transaction Class Exemption (“PTCE”) 95-60) whose underlying assets include less than 25% “plan assets” of any Benefit Plan for the entire period during which it holds its interest in
the Class [E] Notes, who is not and is not an affiliate of a person that has discretionary authority or control with respect to the assets of the Issuing Entity or provides investment advice for a fee (direct or indirect) with respect to the assets
of the Issuing Entity, and for which the purchase and 

  
 Ex. A-3 








 holding of the Class [E] Notes is eligible for and satisfied all conditions for relief under PTCE 95-60 and (b) it is not an employee benefit plan or plan that is subject to any applicable law that is substantially similar to Title I of ERISA or Section 4975 of the Code.] [Any holder of this Class
[A][B][C][D][E] Note that is a Benefit Plan shall be deemed to have represented that the decision to acquire such note has been made by a fiduciary which is an “independent fiduciary with financial expertise” as described in 29 C.F.R. 2510.3-21(c)(1).] 
 [Transfer of this 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 this 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 this Class E Note or interest herein in the form of a Book Entry Note.] 

[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(f) of the Indenture Supplement (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.]

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 2018-2 Notes only represent interest in the Issuing Entity allocated to the Series 2018-2 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. 

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 

  
 Ex. A-7 








 
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 2018-2 Expected Maturity Date is the May 2021 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 2018-2 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 

  
 Ex. A-8 








 
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 and Registrar. No service charge may be imposed for any
such exchange but the Issuing Entity or Transfer Agent and Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. 

The Issuing Entity, the Depositor, the Indenture Trustee and any 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 Issuing Entity, the Depositor or the Indenture Trustee shall be
affected by notice to the contrary. 
 This Note is to be construed in accordance with the laws of the State of New York, without reference
to its conflict of law provisions, and the obligations, rights and remedies of the parties hereunder are to be determined in accordance with such laws.
