WHEREAS, in connection with such sale, transfer and assignment, the Seller desires for the Custodian to act as custodian of such Eligible Receivables for the benefit of the Issuer; and

WHEREAS, GMAC will retain the Receivables in the Accounts in the Pool of Accounts not so sold, transferred and assigned to the Seller (the “Retained Receivables”) and, in connection therewith, the Seller desires for (and GMAC is willing to agree and accept) the Custodian to act as custodian of the Wholesale Security Agreements between GMAC and each Dealer and any other documents and instruments pertaining to the Receivables retained by GMAC (the “Retained Receivables Files,” and together with the Eligible Receivables Files, the “Receivables Files”);

NOW, THEREFORE, in consideration of the mutual agreements herein contained and of other good and valuable consideration the receipt and adequacy of which are hereby acknowledged, the parties agree as follows:

1. Appointment of Custodian; Acknowledgment of Receipt. Subject to the terms and conditions hereof, the Seller hereby appoints the Custodian, and the Custodian hereby accepts such appointment, to act as agent of the Seller as Custodian to maintain custody of the Eligible Receivables Files pertaining to the Eligible Receivables conveyed to the Seller from time to time under the Pooling and Servicing Agreement. The Custodian hereby acknowledges that the Seller desires to sell, transfer and assign all of its right, title and interest in, to and under

such Eligible Receivables and this Custodian Agreement to the Issuer pursuant to the Trust Sale and Servicing Agreement. The Custodian hereby agrees, in connection with such sale, transfer and assignment, to act as Custodian for the benefit of the Issuer with respect to such Receivables. Subject to the terms and conditions hereof and at the request of the Seller, GMAC hereby appoints the Custodian, and the Custodian hereby accepts such appointment, to act as agent of GMAC as Custodian to maintain custody of the Retained Receivables Files pertaining to the Retained Receivables. In performing its duties hereunder, the Custodian agrees to act with reasonable care, using that degree of skill and attention that the Custodian exercises with respect to receivable files relating to comparable wholesale receivables that the Custodian services and holds for itself or others. The Custodian hereby acknowledges receipt of the Receivables Files for (i) each Eligible Receivable conveyed to the Seller and (ii) each Retained Receivable on the date hereof.

2. Maintenance at Office. The Custodian agrees to maintain each Receivables File at one of its branch offices as identified in the List of Branch Offices attached hereto as Exhibit A, or at such other office of the Custodian as shall from time to time be identified to the Issuer upon 30 days’ prior written notice.

3. Duties of Custodian.

(a) Safekeeping. The Custodian shall hold each Receivables File described herein on behalf of the Seller, the Issuer or GMAC, as the case may be, for the use and benefit of the Seller, the Issuer, GMAC and the Interested Parties, as applicable, and maintain such accurate and complete accounts, records and computer systems pertaining to each Receivables File described herein as shall enable GMAC, the Seller and the Issuer to comply with their respective obligations under the Pooling and Servicing Agreement and the Trust Sale and Servicing Agreement. Each Receivable subject hereto shall be identified as such on the books and records of the Custodian to the extent the Custodian reasonably determines to be necessary to comply with the terms and conditions of the Pooling and Servicing Agreement and the Trust Sale and Servicing Agreement. The Custodian shall conduct, or cause to be conducted, periodic physical inspections of the Receivables Files held by it under this Custodian Agreement, and of the related accounts, records and computer systems, in such a manner as shall enable the Issuer, GMAC and the Custodian to verify the accuracy of the Custodian’s inventory and record keeping. The Custodian shall promptly report to the Issuer or GMAC, as applicable, any failure on its part to hold the related Receivables File as described herein and maintain its accounts, records and computer systems as herein provided and promptly take appropriate action to remedy any such failure.

- 2 -

the circumstances provided in the Pooling and Servicing Agreement and the Trust Sale and Servicing Agreement or, in the case of the Retained Receivables, as otherwise requested by GMAC (so long as such request is not inconsistent with the terms of the Pooling and Servicing Agreement and the Trust Sale and Servicing Agreement).

The Custodian further agrees to cooperate with the Servicer in the Servicer’s performance of its duties under the Pooling and Servicing Agreement and the Trust Sale and Servicing Agreement.

4. Instructions; Authority to Act. The Custodian shall be deemed to have received proper instructions from the Issuer or GMAC, as the case may be, with respect to the Receivables Files described herein upon its receipt of written instructions signed by an Authorized Officer. A certified copy of a by-law or of a resolution of the appropriate governing body of the Issuer or GMAC, as the case may be (or, as appropriate, a trustee on behalf of the Issuer), may be received and accepted by the Custodian as conclusive evidence of the authority of any such officer to act and may be considered as in full force and effect until receipt of written notice to the contrary.

6. Advice of Counsel. The Custodian, GMAC, the Seller and, upon execution of the Trust Sale and Servicing Agreement, the Issuer further agree that the Custodian shall be entitled to rely and act upon advice of counsel with respect to its performance hereunder and shall be without liability for any action reasonably taken pursuant to such advice, provided that such action is not in violation of applicable federal or state law.

Notwithstanding the foregoing, if GMAC resigns as Servicer under the Trust Sale and Servicing Agreement or if all of the rights and obligations of the Servicer have been terminated under the Trust Sale and Servicing Agreement, this Custodian Agreement may be terminated by the Issuer or GMAC or by any Persons to whom the Issuer or GMAC has assigned its rights hereunder. As soon as practicable after the termination of this Custodian Agreement, the Custodian shall deliver the Receivables Files described herein to the Issuer, the Issuer’s agent or GMAC at such place or places as the Issuer or GMAC may reasonably designate.
