Ladies and Gentlemen:

Ally Auto Assets LLC, a Delaware limited liability company (the “Depositor”), proposes to sell to the Underwriters $194,000,000 aggregate principal balance of Class A-1 Asset Backed Notes (the “Class A-1 Notes”), $295,000,000 aggregate principal balance of Class A-2 Asset Backed Notes (the “Class A-2 Notes”), $395,000,000 aggregate principal balance of Class A-3 Asset Backed Notes (the “Class A-3 Notes”) and $102,036,000 aggregate principal balance of Class A-4 Asset Backed Notes (the “Class A-4 Notes”, and together with the Class A-1 Notes, the Class A-2 Notes and the Class A-3 Notes, the “Offered Notes”) of the Ally Auto Receivables Trust 2013-SN1 (the “Trust”), to be issued pursuant to an indenture, to be dated as of the Closing Date (as defined herein) (as amended and supplemented from time to time, the “AART Indenture”), between the Trust and Citibank, N.A., as indenture trustee (in such capacity, the “AART Indenture Trustee”). The Trust is also issuing concurrently with the Offered Notes $65,340,000 aggregate principal balance of Class B Asset Backed Notes (the “Class B Notes”) and $38,609,000 aggregate principal balance of Class C Asset Backed Notes (the “Class C Notes”).

The assets of the Trust will include, among other things, secured notes (the “Secured Notes”) issued by Ally Central Originating Lease Trust (“ACOLT”). The Secured Notes will be issued pursuant to an indenture, to be dated as of the Closing Date (as amended and supplemented from time to time, the “ACOLT Indenture”), between ACOLT and Citibank, N.A., as indenture trustee (in such capacity, the “ACOLT Indenture Trustee”). The Secured Notes will initially be issued by ACOLT to Ally Bank, a Utah chartered bank (“Ally Bank”), in exchange

for the transfer by Ally Bank to ACOLT of a pool of new automobile and light duty truck leases and the related leased vehicles (the “Lease Assets”) and certain monies due or received thereunder on and after May 1, 2013 (the “Cutoff Date”), pursuant to a sale and contribution agreement, to be dated as of the Closing Date (as amended and supplemented from time to time, the “Sale and Contribution Agreement”), between ACOLT and Ally Bank. ACOLT’s obligations under the Secured Notes will be secured by the Lease Assets. The Initial ABS Value (as defined in the Administration Agreement (defined herein)) of the Lease Assets will be $1,187,995,481.48. Ally Financial Inc. (“Ally Financial”) will serve as the initial custodian of the Lease Asset Files (as defined in the Administration Agreement) and will continue to service the Lease Assets after their transfer to ACOLT pursuant to a servicing agreement, to be dated as of the Closing Date (the “Servicing Agreement”) between ACOLT and Ally Financial, as servicer and as custodian. Ally Bank will sell the Secured Notes to the Depositor pursuant to a pooling agreement, to be dated as of the Closing Date (as amended and supplemented from time to time, the “Pooling Agreement”), between Ally Bank and the Depositor. The Secured Notes will be transferred by the Depositor to the Trust pursuant to a trust sale agreement, to be dated as of the Closing Date (as amended and supplemented from time to time, the “Trust Sale Agreement”), between the Depositor and the Trust. The Secured Notes will be administered by Ally Financial pursuant to a Administration Agreement, to be dated as of the Closing Date (the “Administration Agreement”) among Ally Financial, as trust administrator, the Depositor and the Trust. The Trust has been formed pursuant to a trust agreement, dated as of May 8, 2013 (to be amended and restated as of the Closing Date, and as further amended and supplemented from time to time, the “Trust Agreement”), between the Depositor and Deutsche Bank Trust Company Delaware, as trustee, acting thereunder not in its individual capacity but solely as trustee of the Trust (the “AART Owner Trustee”).

Any reference herein to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the Exchange Act on or before the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be, deemed to be incorporated therein by reference. Certain terms used herein are defined in Section 18 hereof. Capitalized terms not otherwise defined in this Underwriting Agreement (this “Agreement”) shall have the meanings assigned to them in Part I of Appendix A to the Administration Agreement.

1. Representations and Warranties of the Depositor. The Depositor represents and warrants to, and agrees with, the several underwriters named in Schedule 1 (the “Underwriters”) that:

(a) Each of the Depositor and ACOLT meets the requirements for use of Form S-3 under the Act and has prepared and filed with the Commission a registration statement (No. 333-181915 and No. 000-000000-00, respectively), including a prospectus, on Form S-3 pursuant to Rule 415 under the Act on June 5, 2012, as amended

by Pre-Effective Amendment No. 1 on August 21, 2012, for the registration under the Act of asset-backed securities (issuable in series and classes thereof), including the Secured Notes and the Offered Notes, which registration statement has become effective, and a copy of which, as amended to the date hereof, has heretofore been delivered to the Underwriters. The Depositor has filed or will file with the Commission, pursuant to Rule 424(b), one or more Preliminary Prospectuses and has delivered the Final Preliminary Prospectus to the Underwriters on or prior to the Applicable Time for delivery to prospective investors. The Depositor will file with the Commission pursuant to Rule 424(b) a Final Prospectus relating to the Offered Notes and the method of distribution thereof.

(b) On the Effective Date, the Registration Statement complied, and when each of the Final Preliminary Prospectus and Final Prospectus are first filed in accordance with Rule 424(b), the Final Preliminary Prospectus and the Final Prospectus will comply, in all material respects, with the applicable requirements of the Act; provided, however, that the Depositor has prepared the Final Preliminary Prospectus and the Final Prospectus in reliance upon and in conformity with the guidance from the staff of the Commission set forth in the No-Action Letter, dated November 23, 2010, regarding Regulation AB Items 1103(a)(9) and 1120 (the “No-Action Letter”); on the Effective Date, the Registration Statement did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; on the date of any filing pursuant to Rule 424(b) and on the Closing Date, the Final Prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Depositor makes no representations or warranties as to the information contained in or omitted from the Registration Statement or the Final Prospectus (or any supplement thereto) (i) in reliance upon and in conformity with the Underwriter Information (as defined in Section 8(b)) or (ii) relating to and included in the ABS Tables. As of the Closing Date, the representations and warranties of the Depositor in the Pooling Agreement, the Trust Sale Agreement, the Administration Agreement and the Trust Agreement will be true and correct in all material respects.

(c) As of the Applicable Time, the Disclosure Package did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Depositor makes no representations or warranties as to the information contained in or omitted from the Disclosure Package (i) in reliance upon and in conformity with the Underwriter Information or (ii) included in the ABS Tables.

(d) At the earliest time after the filing of the Registration Statement that the Depositor or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Offered Notes, the Depositor was not an “ineligible issuer,” as defined in Rule 405.

(e) Each Issuer Free Writing Prospectus, as of its issue date, does not and will not include any information that conflicts or will conflict with the information then contained in the Registration Statement; provided, however, that the Depositor makes no representations or warranties as to the information contained in or omitted from any Issuer Free Writing Prospectus (i) in reliance upon and in conformity with the Underwriter Information or (ii) relating to the ABS Tables. If at any time following issuance of an Issuer Free Writing Prospectus there has occurred or does occur an event or development as a result of which such Issuer Free Writing Prospectus would conflict with the information then contained in the Registration Statement or would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, (i) the Depositor has notified or will promptly notify the Underwriters and (ii) the Depositor has amended or supplemented or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(f) This Agreement has been duly authorized, executed and delivered by the Depositor.

(g) As of its date, the Final Preliminary Prospectus did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Depositor makes no representations or warranties as to the information contained in or omitted from the Final Preliminary Prospectus (i) in reliance upon and in conformity with the Underwriter Information, (ii) included in the ABS Tables or (iii) pricing and price dependent information, which information shall appear in the Final Prospectus but not in the Final Preliminary Prospectus.

2. Representations, Warranties and Covenants of the Sponsor. Ally Bank in its capacity as sponsor (the “Sponsor”) represents and warrants to, and agrees with, each Underwriter that the Sponsor or the Depositor has provided a written representation (the “17g-5 Representation”) to each Rating Agency, which satisfies the requirements of paragraph (a)(3)(iii) of Rule 17g-5 of the Exchange Act. Each of the Sponsor and the Depositor has complied and will comply with the 17g-5 Representation other than any breach of the 17g-5 Representation (a) that would not have a material adverse effect on the Offered Notes or (b) arising from a breach by any Underwriter of the representation, warranty and covenant set forth in Section 5(g).

3. Purchase, Sale and Delivery of the Offered Notes. Each Underwriter executing this Agreement on its own behalf and as a Representative of the several Underwriters (the “Representatives”) hereby represents and warrants to the Depositor that it has been authorized by the other Underwriters to execute this Agreement on their behalf. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Depositor agrees to sell to the Underwriters, and each Underwriter, severally and not jointly, agrees to purchase from the Depositor, the respective principal balance of each class of Offered Notes set forth opposite the name of such Underwriter on Schedule 1. Each class of Offered Notes is to be purchased at the respective purchase price set forth on Schedule 2, plus accrued interest to the extent set forth on such Schedule 2.

4. Delivery and Payment. The Depositor will deliver the Offered Notes to the Representatives for the account of the Underwriters against payment of the purchase price and Reserve Account Deposit in immediately available funds, at the office of Xxxxxxxx & Xxxxx LLP, 000 Xxxxx XxXxxxx, Xxxxxxx, Xxxxxxxx 00000, on June 5, 2013 at 10:00 a.m. (Chicago time), or at such other time and place not later than seven full business days thereafter as the Representatives and the Depositor determine, such time being herein referred to as the “Closing Date.” The global notes representing the Offered Notes shall be registered in the name of Cede & Co., the nominee of The Depository Trust Company (“DTC”). The interests of beneficial owners of the Offered Notes will be represented by book entries on the records of DTC and participating members thereof. Definitive notes will be available only under limited circumstances.

5. Offering by Underwriters; Representations and Covenants of the Underwriters.

(a) It is understood that the Underwriters propose to offer the Offered Notes for sale to the public (which may include selected dealers) as set forth in the Final Prospectus. Each Underwriter agrees that all such offers and sales by such Underwriter will be made in compliance with all applicable laws and regulations, including all laws and regulations with respect to pricing of the Offered Notes and disclosure of underwriting commissions from the Depositor or any other person.

(b) The Underwriters have not provided and will not provide any ABS Informational and Computational Material to prospective investors. For the purposes hereof, “ABS Informational and Computational Material” as used herein shall have the meanings given such term in Item 1101(a) of Regulation AB under the Exchange Act.

(c) Each Underwriter represents that it has delivered the Final Preliminary Prospectus and the Bloomberg Screen to prospective investors prior to or at the Applicable Time.

(d) Each Underwriter, solely with respect to itself, represents, as of the Closing Date, that other than the Base Prospectus, any Preliminary Prospectus, the Final Prospectus and any Free Writing Prospectus identified on Schedule 3, it did not provide any prospective investors with any “written communication” (as defined in Rule 405 under the Act) that constitutes an offer to sell or solicitation of an offer to buy the Offered Notes, other than those identified on Schedule 4; provided, however, that, notwithstanding the foregoing, the Depositor agrees that each Underwriter may disseminate without the approval of the Depositor one or more “written communications” (as defined in Rule 405 under the Act) in the form of (i) an Intex CDI file that does not contain any Issuer Information (as defined below) other than Issuer Information contained in any Preliminary Prospectus, (ii) information on Bloomberg to prospective investors relating to (A) the prepayment speed and clean-up call information of the Offered Notes, any derivatives expected to be entered into in connection with the Offered Notes, and the weighted average life and payment window of one or more classes of Offered Notes and (B) a column or other entry showing the status of the subscriptions for the Offered Notes (both for the issuance as a whole and for each Underwriter’s retention) (collectively, the “Bloomberg Information”) or (iii) information customarily included in confirmations of sales of securities and notices of allocations and information

contemplated by Rule 134 of the Act, which, in the case of clauses (ii) or (iii), each Underwriter, solely with respect to itself, represents shall not be required to be filed with the Commission (i) pursuant to the safe harbor provided by Rule 134 or (ii) because such information is a Free Writing Prospectus that is not an Issuer Free Writing Prospectus (each such written communication, an “Underwriter Free Writing Prospectus”). As used herein, the term “Issuer Information” means any information of the type specified in clauses (1) – (5) of footnote 271 of Commission Release No. 33-8591 (Securities Offering Reform), other than Underwriter Derived Information. As used herein, the term “Underwriter Derived Information” shall refer to information of the type described in clause (5) of footnote 271 of Commission Release No. 33-8591 (Securities Offering Reform) when prepared by any Underwriter, including traditional computational and analytical materials prepared by such Underwriter.

(e) Each Underwriter severally and not jointly represents, warrants and agrees with the Depositor that:

(i) each Underwriter Free Writing Prospectus prepared by it will not, as of the date such Underwriter Free Writing Prospectus was conveyed or delivered to any prospective purchaser of Offered Notes, when taken as a whole together with the Disclosure Package, include any untrue statement of a material fact or omit to state any material fact necessary to make the statements contained therein, in the light of the circumstances under which they were made, not misleading; provided, however, that no Underwriter makes such representation, warranty or agreement to the extent such untrue statements in or omissions from any Underwriter Free Writing Prospectus were made in reliance upon and in conformity with any (A) written information furnished to the related Underwriter by the Depositor or Ally Bank expressly for use in such Underwriter Free Writing Prospectus, which information was not corrected by information subsequently provided by the Depositor or Ally Bank to the related Underwriter prior to the time of use of such Underwriter Free Writing Prospectus, (B) information accurately extracted from any Preliminary Prospectus or the Final Prospectus, which information was not corrected by information subsequently provided by the Depositor or Ally Bank to the related Underwriter prior to the time of use of such Underwriter Free Writing Prospectus or (C) Issuer Information (as defined in Section 5(d));

(ii) each Underwriter Free Writing Prospectus prepared by it shall contain a legend substantially in the form of and in compliance with Rule 433(c)(2)(i) of the Act, and shall otherwise conform to any applicable requirements for “free writing prospectuses” under the Act;

(iii) none of the information in any Underwriter Free Writing Prospectus will conflict with the information then contained in the Registration Statement or any prospectus or prospectus supplement that is a part thereof; and

(iv) such Underwriter has in place, and covenants that it shall maintain, internal controls and procedures that it reasonably believes to be sufficient to ensure compliance in all material respects with all applicable legal requirements of the Act and the rules and regulations thereunder with respect to the generation and use of Underwriter Free Writing Prospectuses in connection with the offering of the Offered Notes.

(f) Each Underwriter that uses the Internet or other electronic means to offer or sell the Offered Notes severally and not jointly represents that it has in place, and covenants that it shall maintain, internal controls and procedures which it reasonably believes to be sufficient to ensure compliance in all material respects with all applicable legal requirements under the Act and applicable procedures, if any, worked out with the staff of the Commission relating to the use of the Internet or relating to computerized or electronic means of delivery to prospective investors of the Prospectus and any road show-related materials, including the Road Show, in each case in connection with the offering of the Offered Notes.

(g) Each Underwriter severally and not jointly represents, warrants and agrees with the Depositor and the Sponsor that:

(i)

on and prior to the date of this Agreement, it has not delivered (or caused any person other than the Sponsor or any of its affiliates to deliver) any written Rating Agency Information to any nationally recognized statistical rating organization (each, an “NRSRO”), other than the Rating Agency Information set forth on Schedule 6;

(ii)

on and after the date of this Agreement, it will not deliver (and will not cause any person other than the Sponsor or any of its affiliates to deliver) any written Rating Agency Information to any NRSRO other than with the express written consent of the Sponsor; and

(iii)

it has not communicated any Rating Agency Information orally to any NRSRO except in circumstances where an authorized representative of the Sponsor participated in such oral communications; provided, however, that if an Underwriter receives an oral communication from any NRSRO, such Underwriter is authorized to inform such NRSRO that it will respond to the oral communication with a designated representative from the Sponsor or refer such NRSRO to the Sponsor, who will respond to the oral communication.

(h) As of the Applicable Time and as of the Closing Date, each Underwriter has and will have complied with all of its obligations hereunder.

6. Covenants of the Depositor. The Depositor covenants and agrees with the Underwriters that:

(a) The Depositor shall furnish to the Representatives without charge, during the period mentioned in Section 6(e) below, as many copies of the Final Prospectus and any supplements and amendments thereof or thereto as the Representatives may reasonably request.

(b) The Depositor has filed or shall file each Preliminary Prospectus pursuant to and in accordance with Rule 424(b) not later than the second business day following the date it is first used.

(c) The Depositor shall prepare and file the Final Prospectus pursuant to and in accordance with Rule 424(b) not later than the second business day following the date it is first used.

(d) The Depositor shall advise the Representatives promptly of any proposal to amend or supplement the Registration Statement, any Preliminary Prospectus or the Final Prospectus and shall consult with them and their counsel with respect to any comments they may have on any such proposed amendment or supplement; provided, however, that no such advice or consultation shall be necessary for Exchange Act reports filed by the Depositor in the ordinary course that contain opinions, the Basic Documents or related agreements, monthly distribution reports, annual reports and suspension of duty to report notices.

(e) If, at any time when a prospectus relating to the Offered Notes is (or but for the exemption in Rule 172 would be required to be) delivered under the Act in connection with sales by any Underwriter or dealer, any event occurs as a result of which the Final Preliminary Prospectus or the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Final Preliminary Prospectus or the Final Prospectus to comply with the Act, the Depositor promptly shall (1) notify the Representatives of such event and (2) prepare and file with the Commission, subject to paragraph (d) of this Section 6, an amendment or supplement which will correct such statement or omission or effect such compliance.

(f) The Depositor represents and agrees that, unless it obtains the prior consent of the Representatives, and each Underwriter, severally and not jointly, represents and agrees with the Depositor that, unless it obtains the prior consent of the Depositor, it has not made and will not make any offer relating to the Offered Notes that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a Free Writing Prospectus; provided, however, that the prior consent of the parties hereto shall be deemed to have been given with respect to the Free Writing Prospectuses included in Schedule 3 and Schedule 4 hereto, in the Intex CDI files as described in Section 5(d)(i) above, the Bloomberg Information and the information described in Section 5(d)(iii).

(g) The Depositor shall take such action in order to exempt the Offered Notes from the qualification for offer and sale under the securities or “Blue Sky” laws of such jurisdictions as the Representatives shall reasonably request and to pay all reasonable

expenses (including reasonable fees and disbursements of counsel) in connection with such exemption and in connection with the determination of the legality of the Offered Notes for purchase under the laws of such jurisdictions as the Representatives may designate. Thereafter, until all of the Offered Notes have been retired, the Depositor shall arrange for the filing and making of, and shall pay all fees applicable to, such statements and reports and renewals of registration necessary in order to continue to exempt the Offered Notes for secondary market transactions in the various jurisdictions in which the Offered Notes were originally exempted for sale.

(h) For a period from the date of this Agreement until the retirement of the Offered Notes, or until such time as no Underwriter shall continue to maintain a secondary market in the Offered Notes, whichever first occurs, the Depositor shall deliver or cause to be delivered to the Representatives, upon request, the Servicer’s annual statement as to compliance pursuant to Section 2.16(a) of the Servicing Agreement concerning Item 1123 of Regulation AB and the Report of Assessment of Compliance with Servicing Criteria furnished to the ACOLT Indenture Trustee and the ACOLT Owner Trustee pursuant to Section 2.17(a) of the Servicing Agreement and furnished to the AART Indenture Trustee and the AART Owner Trustee pursuant to Section 4.02(b) of the Administration Agreement concerning Item 1122 of Regulation AB, promptly after the same are furnished to the ACOLT Indenture Trustee, the ACOLT Owner Trustee, the AART Indenture Trustee and the AART Owner Trustee, as applicable.

(i) So long as any of the Offered Notes are outstanding, the Depositor shall furnish to the Representatives (i) as soon as available, a copy of each report of the Depositor filed with the Commission under the Exchange Act or mailed to the holders of the Offered Notes, and (ii) from time to time, such other information concerning the Depositor as the Representatives may reasonably request.

(j) Whether or not the transactions contemplated by this Agreement are consummated, the Depositor shall pay or cause to be paid all expenses incident to the performance of the Depositor’s obligations under this Agreement, and shall pay or cause to be paid or shall reimburse the Underwriters for (i) any reasonable expenses (including reasonable fees and disbursements of outside counsel) incurred by them in connection with the qualification or exemption of the Offered Notes for offer and sale and the determination of their legality for purchase under the laws of such jurisdictions as the Representatives have reasonably requested pursuant to Section 6(g) and the printing of memoranda relating thereto, (ii) any fees charged by investment rating agencies for the rating of the Offered Notes, and (iii) reasonable expenses incurred in printing, if applicable, and distributing any Preliminary Prospectus and the Final Prospectus (including any amendments and supplements thereto) to the Underwriters.

(k) To the extent, if any, that any rating necessary to satisfy the condition set forth in Section 7(k) is conditioned upon the furnishing of documents or the taking of other actions by the Depositor on or after the Closing Date, the Depositor shall furnish such documents and take such other actions.

(l) If, during the period after the Closing Date in which a prospectus relating to the Offered Notes is required to be delivered under the Act, the Depositor receives notice that a stop order suspending the effectiveness of the Registration Statement or preventing the offer and sale of the Offered Notes is in effect, the Depositor shall advise the Representatives of the issuance of such stop order.

(m) The Depositor and the Sponsor each acknowledges and agrees that each Underwriter is acting solely in the capacity of an arm’s length contractual counterparty to the Depositor and the Sponsor with respect to the offering of the Offered Notes contemplated hereby (including in connection with determining the terms of the offering) and not as a fiduciary to, or an agent of, the Depositor, the Sponsor or any other person. Additionally, no Underwriter is advising the Depositor, the Sponsor or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Depositor and the Sponsor shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and no Underwriter shall have any responsibility or liability to the Depositor, the Sponsor or any other person with respect thereto. Any review by the Underwriters of the Depositor, the Sponsor, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Depositor, the Sponsor or any other party.

(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless each of Ally Bank and the Depositor, its respective directors, its respective officers and any person controlling either Ally Bank or the Depositor, as applicable, to the same extent as the foregoing indemnity from each of Ally Bank and the Depositor to such Underwriter in Section 8(a), but only with reference to

(i) information in reliance upon or conformity with the Underwriter Information; and the Depositor acknowledges that the following items constitute the only “Underwriter Information”:

(1) the statements made by the Underwriters under the caption “Underwriting” in the Disclosure Package and the Final Prospectus with respect to the following:

(a.) the legal names of the Underwriters in the table titled “Aggregate Principal Amount to be Purchased”;

(b.) the table relating to selling concessions and reallowances and the paragraph of text preceding such table; and

(c.) to the extent the sixth to last sentence under the caption “Underwriting”¹ applies to the Underwriters, the representation of the Depositor and the Underwriters relating to purchase transactions, over-allotment transactions, stabilizing transactions, syndicate covering transactions and penalty bids; and

(2) each of the Underwriters’ “street names” on the front cover and the back cover, if any, of the Final Preliminary Prospectus and the Final Prospectus; and

(ii) any Underwriter Free Writing Prospectus (as defined in Section 5(d)), when taken as a whole together with the Disclosure Package;

provided, however, that no Underwriter shall be liable to the extent that any such loss, claim, damage or liability arises out of or is based upon any statement in or omission from any Underwriter Free Writing Prospectus in reliance upon and in conformity with (A) any written information furnished to the related Underwriter by the Depositor or Ally Bank expressly for use therein, which information was not corrected by information subsequently provided by the Depositor or Ally Bank to such Underwriter prior to the time of use of such Underwriter Free Writing Prospectus, (B) information accurately extracted from any Preliminary Prospectus or the Final Prospectus, which information was not corrected by information subsequently provided by the Depositor or Ally Bank to the related Underwriter prior to the time of use of such Underwriter Free Writing Prospectus or (C) Issuer Information (as defined in Section 5(d)).

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either of Sections 8(a) or (b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such

The sixth to last sentence under the caption “Underwriting” reads as follows: “Neither the depositor nor any of the underwriters represent that the underwriters will engage in any of these transactions or that these transactions, once commenced, will not be discontinued without notice at any time.”

indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by the Representatives in the case of parties indemnified pursuant to Section 8(a) and by Ally Bank and the Depositor in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened proceeding in respect of which any indemnified party is a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or admission of, fault, culpability or a failure to act by or on behalf of the indemnified party.

If the indemnification provided for in this Section 8 is unavailable to an indemnified party under Section 8(a) or 8(b) or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect not only the relative benefits but also the relative fault of Ally Bank and/or the Depositor on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of Ally Bank and/or the Depositor on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by either of Ally Bank or the Depositor, as applicable, or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

Each of Ally Bank, the Depositor and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation or by any other method of allocation which does not take account of the considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.

Notwithstanding the provisions of this Section 8, the Underwriters shall not be required to contribute any amount in excess of the amount by which the total price at which the Offered Notes were offered for sale exceeds the amount of any damages which the Underwriters have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 8 to indemnify and contribute are several in proportion to their respective underwriting obligations and not joint.

The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of each of Ally Bank and the Depositor, as applicable, in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by any Underwriter or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of either of Ally Bank or the Depositor, as applicable, together with its respective directors or officers or any person controlling such party, and (iii) acceptance of, and payment for, any of the Offered Notes.

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Offered Notes agreed to be purchased by such Underwriters hereunder and such failure to purchase or pay shall constitute a default in the performance of its or their obligations under this Agreement, the Representatives may make arrangements satisfactory to the Depositor in its sole discretion for the purchase of such Offered Notes by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the remaining Underwriters shall be obligated severally and not jointly to take up and pay for (in the respective proportions that the amount of Offered Notes set forth opposite their names in Schedule 1 bears to the aggregate amount of Offered Notes set forth opposite the names of all the remaining Underwriters) the Offered Notes which the defaulting Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Offered Notes which the defaulting Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of all of the Offered Notes set forth in Schedule 1, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Offered Notes and if such nondefaulting Underwriters do not purchase all the Offered Notes, this Agreement will terminate without liability (except the Depositor’s liability under Section 6(j)) to any nondefaulting Underwriter, the Trust or the Depositor (other than under Section 8). In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding seven days, as the Depositor shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any Underwriter of its liability, if any, to the Depositor and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. (a) If this Agreement shall be terminated by the Representatives because of any failure or refusal on the part of either of Ally Bank or the Depositor to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason either of Ally Bank or the Depositor shall be unable to perform its obligations under this Agreement, Ally

Bank and the Depositor, jointly and severally, shall reimburse the Underwriters for all reasonable out-of-pocket expenses (including the reasonable fees and disbursements of their outside counsel) reasonably incurred by the Underwriters in connection with the offering of the Offered Notes.

(b) The Representatives may terminate this Agreement (upon consultation with each of Ally Bank and the Depositor) at any time prior to the Closing Date if, in the opinion of the Representatives, there shall have been a change in national or international financial, political or economic conditions that in their view will have a materially adverse effect on the success of the offering and distribution of or a secondary market for the Offered Notes in the United States. After consultation with each of Ally Bank and the Depositor, the parties to this Agreement shall be released and discharged from their respective obligations under this Agreement without liability on the part of either the Underwriters or on the part of either of Ally Bank or the Depositor (other than under Section 8), and, notwithstanding Section 10(a), each party will pay its own expenses.

11. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of each of Ally Bank and the Depositor or its respective officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriters or either of Ally Bank or the Depositor or any of their respective officers or directors or any controlling persons, and will survive delivery of and payment for the Offered Notes.

L. 107-56 (signed into law October 26, 2001)), the Representatives are each required to obtain, verify and record information that identifies its clients, including the Depositor, which information may include the name and address of its clients, as well as other information that will allow the Underwriters to properly identify its clients.
