ADMINISTRATION AND SERVICING OF RECEIVABLES

     SECTION 3.01 Duties of the Servicer . (a) The Servicer is hereby appointed and authorized to act as agent for the Owner of the Receivables and in such capacity shall manage, service, administer and make collections on the Receivables with reasonable care, using that degree of skill and attention that the Servicer exercises with respect to comparable motor vehicle related receivables that it services for itself or others. The Servicer hereby accepts such appointment and authorization and agrees to perform the duties of Servicer with respect to the Receivables set forth herein and in the Further Transfer and Servicing Agreements.

          (b) The Servicer’s duties shall include collection and posting of all payments, responding to inquiries of Obligors, investigating delinquencies, sending payment coupons to Obligors, reporting tax information to Obligors, policing the collateral, accounting for collections and furnishing monthly and annual statements to the Owner of any Receivables with respect to distributions, generating federal income tax information and performing the other duties specified herein. Subject to the provisions of Section 3.02 , the Servicer shall follow its customary standards, policies and procedures and shall have full power and authority, acting alone, to do any and all things in connection with such managing, servicing, administration and collection that it may deem necessary or desirable.

          (c) Without limiting the generality of the foregoing, the Servicer is hereby authorized and empowered by the Owner of the Receivables, pursuant to this Section 3.01 , to execute and deliver, on behalf of all Interested Parties, or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge, and all other comparable instruments, with respect to the Receivables and the Financed Vehicles. The Servicer is hereby authorized to commence, in its own name or in the name of the Owner of such Receivable a legal proceeding, whether through judicial process or (with respect to repossession of a Financed Vehicle) non-judicial process, to enforce a Liquidating Receivable as contemplated by Section 3.04 , to enforce all obligations of GMAC and CARI under this Agreement and under the Further Transfer and Servicing Agreements or to commence or participate in a legal proceeding (including a bankruptcy case) relating to or involving a Receivable or a Liquidating Receivable. If the Servicer commences or participates in such a legal proceeding in its own name, the Servicer is hereby authorized and empowered by the Owner of the Receivables pursuant to this

4

Section 3.01 to obtain possession of the related Financed Vehicle and immediately and without further action on the part of the Owner or the Servicer, the Owner of such Receivable shall thereupon automatically assign in trust such Receivable and the security interest in the related Financed Vehicle to the Servicer for the benefit of the Interested Parties for purposes of commencing or participating in any such proceeding as a party or claimant. Upon such automatic assignment, the Servicer will be, and will have all the rights and duties of, a secured party under the UCC and other applicable law with respect to such Receivable and the related Financed Vehicle. At the Servicer’s request from time to time, the Owner of a Receivable assigned under this Section 3.01 shall provide the Servicer with evidence of the assignment in trust for the benefit of the Interested Parties as may be reasonably necessary for the Servicer to take any of the actions set forth in the following sentence.

          (d) The Servicer is hereby authorized and empowered by the Owner of a Receivable to execute and deliver in the Servicer’s name any notices, demands, claims, complaints, responses, affidavits or other documents or instruments in connection with any such proceeding. Any Owner of Receivables shall furnish the Servicer with any powers of attorney and other documents and take any other steps which the Servicer may deem necessary or appropriate to enable the Servicer to carry out its servicing and administrative duties under this Agreement and the Further Transfer and Servicing Agreements. Except to the extent required by the preceding two sentences, the authority and rights granted to the Servicer in this Section 3.01 shall be nonexclusive and shall not be construed to be in derogation of the retention by the Owner of a Receivable of equivalent authority and rights.

     SECTION 3.02 Collection of Receivable Payments . The Servicer shall make reasonable efforts to collect all payments called for under the terms and provisions of the Receivables as and when the same shall become due, and shall follow such collection practices, policies and procedures as it follows with respect to comparable motor vehicle related receivables that it services for itself or others in connection therewith. Except as provided in Section 3.07(a)(iii) , the Servicer is hereby authorized to grant extensions, rebates or adjustments on a Receivable without the prior consent of the Owner of such Receivable. The Servicer is authorized in its discretion to waive any prepayment charge, late payment charge or any other fees that may be collected in the ordinary course of servicing such Receivable.

     SECTION 3.03 Rebates on Full Prepayments on Scheduled Interest Receivables . If the amount of a full Prepayment by an Obligor under a Scheduled Interest Receivable, after adjustment for the Rebate, is less than the amount that would be payable under the actuarial method if a full Prepayment were made at the end of the billing month under such Scheduled Interest Receivable, either because the Rebate calculated under the terms of such Receivable is greater than the amount calculable under the actuarial method or because the Servicer’s customary servicing procedure is to credit a greater Rebate, the Servicer, as part of its servicing duties, shall remit such difference to the Owner of such Receivable.

     SECTION 3.04 Realization Upon Liquidating Receivables . The Servicer shall use reasonable efforts, consistent with its customary practices, policies and procedures, to repossess or otherwise comparably convert the ownership of any Financed Vehicle that it has reasonably determined should be repossessed or otherwise converted following a default under the Receivable secured by the Financed Vehicle. The Servicer is authorized to follow such

5

customary practices, policies and procedures as it follows with respect to comparable motor vehicle related receivables that it services for itself or others, which customary practices, policies and procedures may include reasonable efforts to realize upon any recourse to Dealers, selling the related Financed Vehicle at public or private sale and other actions by the Servicer in order to realize upon such a Receivable. The foregoing is subject to the provision that, in any case in which the Financed Vehicle shall have suffered damage, the Servicer shall not expend funds in connection with any repair or towards the repossession of such Financed Vehicle unless it shall determine in its discretion that such repair and/or repossession shall increase the proceeds of liquidation of the related Receivable by an amount greater than the amount of such expenses. The Servicer shall be entitled to receive Liquidation Expenses with respect to each Liquidating Receivable at such time as the Receivable becomes a Liquidating Receivable (or as may otherwise be provided in the Further Transfer and Servicing Agreements).

     SECTION 3.05 Maintenance of Insurance Policies . The Servicer shall, in accordance with its customary practices, policies and procedures, require that each Obligor shall have obtained physical damage insurance covering the Financed Vehicle as of the execution of the related Receivable. The Servicer shall, in accordance with its customary practices, policies and procedures, monitor such physical damage insurance with respect to each Receivable.

     SECTION 3.06 Maintenance of Security Interests in Vehicles . The Servicer shall, in accordance with its customary practices, policies and procedures and at its own expense, take such steps as are necessary to maintain perfection of the security interest created by each Receivable in the related Financed Vehicle. The Owner of each Receivable hereby authorizes the Servicer to re-perfect such security interest on behalf of such Owner, as necessary because of the relocation of a Financed Vehicle, or for any other reason.

     SECTION 3.07 Covenants, Representations and Warranties of the Servicer . As of the Closing Date, the Servicer hereby makes the following representations, warranties and covenants on which CARI relies in accepting the Receivables hereunder and pursuant to the related First Step Receivables Assignment, and on which the Issuing Entity shall rely in accepting such Receivables and executing and delivering the Securities under the Further Transfer and Servicing Agreements.
