This letter constitutes a “Confirmation” as referred to in the Primary ISDA Agreement specified below.

The definitions and provisions contained in the 2006 ISDA Definitions (the “Definitions”), as published by the International Swaps and Derivatives Association, Inc.

The parties agree that this transaction is a Transaction under the ISDA Master Agreement (Multicurrency-Cross Border) of the parties dated as of August 18, 2010. The agreement is comprised of the printed form of such agreement as published by ISDA, as supplemented and modified by a Schedule (the “Primary ISDA Agreement”).

This Confirmation constitutes a binding agreement between you and us and will supplement, form a part of, and be subject to the Primary ISDA Agreement described above as amended and supplemented from time to time.

The Counterparty and the Trust acknowledge that this Transaction relates to the Class A-2 Floating Rate Asset Backed Notes (the “Notes” or “Reference Notes”) issued by the Trust for value pursuant to and subject to the Indenture.

Capitalized terms used and not otherwise defined herein, in the Primary ISDA Agreement or in the Definitions shall have the meanings assigned to them in Exhibit A hereto, as applicable.

In addition, on each Determination Date the Calculation Agent shall deliver to the Counterparty (by facsimile, or email, with hard copy to follow) a statement (the “Calculation Statement”) setting forth with respect to the close of business on the immediately preceding Distribution Date the Reference Note Balance as of such Distribution Date.

The Trust will give the Counterparty prompt written notice of any “Event of Default” under the Indenture (and in no event more than five Business Days following such “Event of Default”).

4.	Credit Downgrade:

(A) Xxxxx’x Downgrade.

If the Counterparty (or another Relevant Entity) fails to satisfy the Xxxxx’x First Trigger Required Ratings, the Counterparty shall promptly notify the Trust (and any permitted assignee or transferee of the Trust) and Ally Financial of such event and shall, within 30 Local Business Days after the occurrence of such event, at the Counterparty’s sole expense, either:

(1) obtain a Substitute Swap Provider acceptable to the Trust and replace this Transaction with a swap transaction on substantially similar terms or with such other amendments as consented to in writing by the Trust (which consent shall not be unreasonably withheld) and satisfy the Rating Agency Condition. Upon any such replacement of this Transaction with a Substitute Swap Provider, any and all collateral posted by the Counterparty shall be returned to it within one (1) Business Day and any other form of collateral arrangement (including letters of credit, surety bond or other guarantee) provided by or on behalf of the Counterparty shall terminate; or

(2) post collateral for the benefit of the Trust in accordance with the Credit Support Annex hereto (“CSA”); or

(3) obtain an Eligible Guarantee.

Notwithstanding the foregoing, if the Counterparty (or another Relevant Entity) fails to satisfy the Xxxxx’x Second Trigger Required Ratings, the Counterparty shall promptly notify the Trust (and any permitted assignee or transferee of the Trust) and Ally Financial of such event and shall, within 30 Local Business Days of such failure to satisfy the Xxxxx’x Second Trigger Required Ratings, at the Counterparty’s sole expense, use commercially reasonable efforts to either (a) obtain a Substitute Swap Provider as described in clause (1) above and satisfy the Rating Agency Condition, or (b) obtain an Eligible Guarantee. Following notice to the Trust and before obtaining a Substitute Swap Provider or an Eligible Guarantee, the Counterparty shall also post collateral pursuant to the terms of the CSA until it is replaced by the Substitute Swap Provider or provides an Eligible Guarantee.

(B) S&P Downgrade.

(1) If an S&P Collateralization Event occurs with respect to each Relevant Entity, the Counterparty shall at its sole expense, post Eligible Collateral for the benefit of the Trust in the amount and on the terms then applicable under the CSA. At any time following an S&P Collateralization Event, and so long as no S&P Substitution Event occurs, if the Counterparty elects, the Counterparty may (i) at its sole expense, assign its rights and obligations under this Transaction to a Substitute Swap Provider pursuant to a Permitted Transfer, provided that (x) no termination payments or other settlement amounts are payable by the Trust to either the Counterparty or the Substitute Swap Provider at the time of or as a result of such assignment by the Counterparty and (y) any termination payments or other settlement amounts are to be settled directly between the Counterparty and the Substitute Swap Provider; or (ii) at its sole expense, procure an Eligible Guarantee of the Counterparty’s obligations hereunder by a guarantor that is an Eligible Guarantor. Upon the successful consummation of any assignment to a Substitute Swap Provider or the delivery of any Eligible Guarantee as contemplated in this Section 4(B)(1), any obligation of the Counterparty to post and maintain collateral under the CSA shall terminate and the Trust shall return to the Counterparty any then-posted collateral within one (1) Business Day and any other form of collateral arrangement (including letters of credit, surety bond or other guarantee) provided by or on behalf of the Counterparty shall terminate (it being understood that until such time, if any, as the Counterparty completes the assignment of its rights and obligations hereunder to a Substitute Swap Provider or procures an Eligible Guarantee of such obligations, the Counterparty shall remain obligated to post Eligible Collateral to the extent and on the terms required by the CSA).

(2) If an S&P Substitution Event occurs with respect to each Relevant Entity, the Counterparty shall (a) within 10 Local Business Days of the occurrence of such S&P Substitution Event and at its sole expense, post Eligible Collateral for the benefit of the Trust in the amount and on the terms then applicable under the CSA, and (b) at its sole expense, use commercially reasonable efforts to, within 60 calendar days of the occurrence of such S&P Substitution Event, either (i) assign its rights and obligations under this Transaction to a Substitute Swap Provider pursuant to a Permitted Transfer, provided that (x) no termination payments or other settlement amounts are payable by the Trust to either the Counterparty or the Substitute Swap Provider at the time of or as a result of such assignment by the Counterparty and (y) any termination payments or other settlement amounts are to be settled directly between the Counterparty and the Substitute Swap Provider, or (ii) procure an Eligible Guarantee of the Counterparty’s obligations hereunder by a guarantor that is an Eligible Guarantor. Upon the successful consummation of any assignment to a Substitute Swap Provider or the delivery of any Eligible Guarantee as contemplated in this Section 4(B)(2), any obligation of the Counterparty to post and maintain collateral under the CSA shall terminate and the Trust shall return to the Counterparty any then-posted collateral within one (1) Business Day and any other form of collateral arrangement (including letters of credit, surety bond or other guarantee) provided by or on behalf of the Counterparty shall terminate.

Upon any replacement of this Transaction with a swap transaction with a Substitute Swap Provider, any and all collateral posted by the Counterparty shall be returned to it within one (1) Business Day and any other form of collateral arrangement (including letters of credit, surety bond or other guarantee) provided by or on behalf of the Counterparty shall terminate.

In the event that the Counterparty fails to satisfy its obligations set forth above in this Section 4, such failure shall be an Additional Termination Event with the Counterparty as the sole Affected Party and this Transaction as the sole Affected Transaction. For the avoidance of doubt, the Counterparty and the Trust acknowledge and agree that any such failure shall not constitute an Event of Default.

The following terms shall have the following meanings in this Confirmation:

“Calculation Period”: means, with respect to each party hereunder, each period from, and including one Period End Date of that party to, but excluding, the next following Period End Date of that party during the Term of the Swap Transaction, except that the initial Calculation Period for that party will commence on, and include, the Effective Date.

“Depositor”: Ally Auto Assets LLC, which has executed the Trust Sale and Servicing Agreement as the Depositor, or its successor in interest pursuant to Section 3.03 of the Trust Sale and Servicing Agreement.

“Determination Date”: the tenth (10th) day of each calendar month, or if such tenth (10th) day is not a Business Day, the next succeeding Business Day.

“Distribution Date”: the fifteenth (15th) day of each succeeding calendar month following the Effective Date or, if such fifteenth (15th) day is not a Business Day, the next such succeeding Business Day, commencing September 15, 2010.

“LIBOR”: with respect to each Calculation Period other than the initial Calculation Period, the rate for deposits in U.S. Dollars for a period of one month which appears on Reuters Screen LIBOR01 Page as of 11:00 a.m., London time, on the day that is two LIBOR Business Days prior to the first day of such Calculation Period (and, in the case of the initial Calculation Period, two LIBOR Business Days prior to the Effective Date). If such rate does not appear on that date on Reuters Screen LIBOR01 Page (or any other page as may replace that page on that service, or if that service is no longer offered, any other service for displaying LIBOR or comparable rates as may be selected by the Indenture Trustee after consultation with the Depositor), then LIBOR will be the Reference Bank Rate.

“Period End Date”: means the Fixed Rate Payer Period End Date or the Floating Rate Payer Period End Date.

The reference banks shall be four major banks that are engaged in transactions in the London interbank market, selected by the Indenture Trustee

If on that date fewer than two quotations are provided as requested, the rate will be the arithmetic mean, rounded upwards to the nearest one-sixteenth of one percent, of the rates quoted by one or more major banks in New York City, selected by the Indenture Trustee after consultation with the Depositor, as of 11:00 a.m., New York City time, on that date to leading European banks for United States dollar deposits for a period of one month in amounts approximately equal to the principal amount of the Reference Notes then outstanding.
