CONVEYANCE OF RECEIVABLES; ISSUANCE OF SECURITIES

Section 2.01 Conveyance of Receivables.

(a) Receivables. In consideration of the Issuing Entity’s delivery of the Notes and the Certificates to, or upon the order of, the Depositor, the Depositor does hereby enter into this Agreement and the Second Step Receivables Assignment in the form attached as Exhibit B to this Agreement (the “Second Step Receivables Assignment”) and agrees to fulfill all of its obligations hereunder and thereunder and to sell, transfer, assign and otherwise convey to the Issuing Entity, without recourse:

(i) all right, title and interest of the Depositor in, to and under the Receivables listed on the Schedule of Receivables and all monies received thereon on and after the Cutoff Date, exclusive of any amounts allocable to the premium for physical damage collateral protection insurance required by the Servicer or the Seller covering any related Financed Vehicle;

(ii) the interest of the Depositor in the security interests in the Financed Vehicles granted by Obligors pursuant to the Receivables and, to the extent permitted by law, any accessions thereto;

(iii) the interest of the Depositor in any proceeds from claims on any physical damage, credit life, credit disability or other insurance policies covering related Financed Vehicles or Obligors;

(iv) the interest of the Depositor in any proceeds from recourse against Dealers on the Receivables;

(v) all right, title and interest of the Depositor in, to and under the Pooling Agreement, the First Step Receivables Assignment, the Servicing Agreement and the Custodian Agreement, including the right of the Depositor to cause the Seller or Servicer to repurchase Receivables under certain circumstances; and

(vi) all present and future claims, demands, causes and choses in action in respect of any or all of the foregoing described in clauses (i) through (v) above and all payments on or under and all proceeds of every kind and nature whatsoever in respect of any or all of the foregoing, including all proceeds of the conversion of any or all of the foregoing, voluntary or involuntary, into cash or other liquid property, all cash proceeds, accounts, accounts receivable, notes, drafts, acceptances, chattel paper, checks, deposit accounts, insurance proceeds, investment property, payment intangibles, general intangibles, condemnation awards, rights to payment of any and every kind and other forms of obligations and receivables, instruments and other property which at any time constitute all or part of or are included in the proceeds of any of the foregoing.

(b) It is the intention of the Depositor and the Issuing Entity that the transfers and assignments contemplated by this Agreement and the Second Step Receivables Assignment shall constitute sales of the Receivables from the Depositor to the Issuing Entity for the purpose of applicable bankruptcy, insolvency, reorganization and other similar laws, so that the beneficial interest in and title to the Receivables shall not be part of the Depositor’s estate in the event of the filing of a bankruptcy petition by or against the Depositor under any bankruptcy law.

(c) The foregoing sales, transfers, assignments and other conveyances do not constitute and are not intended to result in the creation of or an assumption by the Issuing Entity of any obligation of the Servicer, the Depositor or any other Person to the Obligors, Dealers, insurers or any other Person in connection with the Receivables, any Dealer Agreements, any insurance policies or any other agreement or instrument relating to any of them.

Section 2.02 Acceptance by Issuing Entity. The Issuing Entity does hereby accept all consideration conveyed by the Depositor pursuant to Section 2.01(a), and declares that the Issuing Entity shall hold such consideration upon the trust set forth in the Trust Agreement for the benefit of the Certificateholders, subject to the terms and conditions of the Indenture, this Agreement and the Second Step Receivables Assignment and the rights of the Noteholders with respect thereto. The Issuing Entity hereby agrees to and accepts the appointment and authorization of Ally Financial as Servicer under Section 2.01 of the Servicing Agreement. The parties agree that this Agreement, the Second Step Receivables Assignment, the Indenture, the Trust Agreement, the Notes and the Certificates constitute the Further Transfer Agreements for purposes of the Pooling Agreement.

Section 2.03 Representations and Warranties as to the Receivables. Pursuant to Section 2.01(a)(v), the Depositor assigns to the Issuing Entity all of its right, title and interest in, to and under the Pooling Agreement. Such assigned right, title and interest includes the benefit of the representations and warranties of the Seller made to the Depositor pursuant to Section 3.01 of the Pooling Agreement. The Depositor hereby represents and warrants to the Issuing Entity that the Depositor has taken no action which would cause such representations and warranties of the Seller to be false in any material respect as of the Closing Date. The Depositor further acknowledges that the Issuing Entity and its permitted assignees rely on the representations and warranties of the Depositor under this Agreement and of the Seller under the Pooling Agreement in accepting the Receivables and executing and delivering the Notes and the Certificates. The foregoing representation and warranty speaks as of the Closing Date, but shall survive the sale, transfer and assignment of the Receivables to the Issuing Entity and the pledge thereof to the Indenture Trustee pursuant to the Indenture.

Section 2.04 Repurchase of Receivables Upon Breach of Warranty. Upon discovery by the Seller, the Depositor, the Servicer, the Owner Trustee or the Indenture Trustee of a breach of any of the representations and warranties in Section 3.01 of the Pooling Agreement or in Section 2.03 or Section 3.01 of this Agreement that materially and adversely affects the interests of the Noteholders or the Certificateholders in any Receivable, the party discovering such breach shall give prompt written notice thereof to the others. As of the last day of the second Monthly Period following its discovery or its receipt of notice of such breach (or, at the Depositor’s election, the last day of the first Monthly Period following such discovery or receipt of notice), unless such breach shall have been cured in all material respects, in the event of a breach of the representations and warranties made by the Depositor in Section 2.03 or Section 3.01, the Depositor shall repurchase, or in the event of a breach of a representation and warranty under Section 3.01 of the Pooling Agreement, the Depositor shall use reasonable efforts to enforce the obligation of the Seller under Section 4.04 of the Pooling Agreement to repurchase such Receivable from the Issuing Entity on the related Distribution Date. The repurchase price to be paid by the breaching party (the “Warranty Purchaser”) shall be an amount equal to the Warranty Payment calculated as of the last day of the related Monthly Period. It is understood and agreed that the obligation of the Warranty Purchaser to repurchase any Receivable as to which a breach has occurred and is continuing, and the obligation of the Depositor to enforce the Seller’s obligation to repurchase such Receivables pursuant to the Pooling Agreement shall, if such obligations are fulfilled, constitute the sole remedy against the Depositor or the Seller for such breach available to the Issuing Entity, the Financial Parties, the Owner Trustee or the Indenture Trustee.

The Depositor and any director or officer or employee or agent of the Depositor may rely in good faith on the advice of counsel or on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising under this Agreement and the Second Step Receivables Assignment. The Depositor and any director or officer or employee or agent of the Depositor shall be reimbursed by the Indenture Trustee or Owner Trustee, as applicable, for any contractual damages, liability or expense incurred by reason of such trustee’s willful misfeasance, bad faith or negligence (gross negligence in the case of the Owner Trustee) (except errors in judgment) in the performance of its duties under this Agreement, the Second Step Receivables Assignment, the Indenture or the Trust Agreement, or by reason of reckless disregard of its obligations and duties under this Agreement, the Second Step Receivables Assignment, the Indenture or the Trust Agreement. In no event, however, shall the Indenture Trustee or the Owner Trustee be liable to the Depositor for any damages in the nature of special, indirect or consequential damages, however styled, including lost profits. The Depositor shall not be under any obligation to appear in, prosecute or defend any legal action that is not incidental to its obligations as the Depositor of the Receivables under this Agreement and the Second Step Receivables Assignment and that in its opinion may involve it in any expense or liability.

Each of the Depositor and any Person controlling, controlled by or under common control with the Depositor may in its individual or any other capacity become the owner or pledgee of Notes or Certificates with the same rights as it would have if it were not the Depositor or an affiliate thereof, except as otherwise specifically provided herein. Except as otherwise provided herein, Notes or Certificates so owned by or pledged to the Depositor or such controlling or commonly controlled Person shall have an equal and proportionate benefit under the provisions of this Agreement, without preference, priority or distinction as among all of such Notes or Certificates, respectively.

The Indenture Trustee and the Owner Trustee may, but shall not be obligated to, enter into any such amendment which affects such trustee’s own rights, duties or immunities under this Agreement or otherwise.

(b) The Depositor shall not change its State of formation or its name, identity or structure in any manner that would, could or might make any financing statement or continuation statement filed in accordance with paragraph (a) above seriously misleading within the meaning of the UCC, unless it shall have given the Indenture Trustee and the Owner Trustee at least sixty (60) days prior written notice thereof.

(c) The Depositor shall give the Indenture Trustee and the Owner Trustee at least sixty (60) days prior written notice of any relocation of its principal executive office or change of its jurisdiction of formation if, as a result of such relocation or change of jurisdiction, the applicable provisions of the UCC would require the filing of any amendment of any previously filed financing or continuation statement or of any new financing statement.

Section 4.05 Severability of Provisions. If any one or more of the covenants, agreements, provisions or terms of this Agreement shall be for any reason whatsoever held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this Agreement and shall in no way affect the validity or enforceability of the other provisions of this Agreement or of the Securities or the rights of the holders thereof.
