2

(ii) on the Addition Date for each Additional Account, sell, transfer, assign, set over and otherwise convey, without recourse (except as expressly provided herein), to the Purchaser (A) all of its right, title and interest in, to and under each Receivable existing in or arising in connection with each such Additional Account (from and including the related Additional Cutoff Date to and including the related Addition Date) and all Related Security, including the Seller’s interest in the security interests granted by the Dealers in the related Vehicles and any subordinated security interests in other Collateral with respect to such Receivable owned by the Seller at the close of business on the related Additional Cutoff Date and not previously sold to the Purchaser pursuant hereto, (B) all of its rights under the related Sales and Service Agreement, (C) all of its rights under intercreditor agreements with third-party creditors of Dealers with respect to each such Additional Account, (D) all of its rights under the related Floorplan Financing Agreement, (E) all proceeds of the foregoing owned by the Seller at the close of business on such Additional Cutoff Date and (F) all monies due or to become due and all amounts received with respect thereto and all proceeds thereof (including “proceeds,” as defined in the UCC as in effect in the applicable jurisdiction) and Recoveries with respect thereto; and

(b) The foregoing sales, transfers, assignments, set-overs and conveyances, and any subsequent sales, transfers, assignments, set-overs and conveyances of additional assets, do not constitute, and are not intended to result in, the creation, or an assumption by the Purchaser, of any obligation of the Servicer, the Seller, GM or any other Person in connection with the Accounts, the related Receivables or any agreement or instrument relating thereto, including any obligation to any Dealers or GM. Such sales, transfers, assignments, set-overs and conveyances are not sales, transfers, assignments, set-overs and conveyances of the Accounts; they are sales, transfers, assignments, set-overs and conveyances of the Receivables arising in connection therewith and the Related Security.

3

(c) In connection with such sales, the Seller will record and file, to the extent it has not done so, at its own expense, a financing statement on form UCC-1 or any other applicable form (and continuation statements when applicable) naming the Seller as “seller” and the Purchaser as “buyer” thereon with respect to the Receivables subject to this Agreement for the sale of “instruments”, “chattel paper”, “general intangibles”, “payment intangibles” or “accounts” (as defined in the UCC as in effect in the applicable jurisdiction) meeting the requirements of Applicable Law in such manner and in such jurisdictions as are necessary to perfect the sale and assignment of the Receivables and the Related Security to the Purchaser, and to deliver a file-stamped copy of such financing statements or other evidence of such filing to the Purchaser within 10 days after the first Series Issuance Date, in the case of the Initial Accounts, and (if any additional filing is necessary) the applicable Addition Date, in the case of Additional Accounts. The Purchaser is under no obligation whatsoever to file such financing statement, or a continuation statement to such financing statement, or to make any other filing under Applicable Law in connection with such sales.

(d) The Seller and the Purchaser intend that all transfers of Receivables under this Agreement constitute sales of the Receivables and not transfers for security for a loan. However, if the transfers of the Receivables hereunder were to be characterized as transfers for security and not as sales, then (i) the Seller will be deemed to have granted, and hereby grants, to the Purchaser a security interest in all of the Seller’s right, title and interest, whether now owned or hereafter acquired, in, to and under each Receivable, the Related Security, all other personal property described from time to time in Section 2.01(a) and all monies due or to become due and all amounts received with respect thereto and all proceeds thereof (including “proceeds,” as defined in the UCC as in effect in the applicable jurisdiction) and Recoveries with respect thereto, (ii) this Agreement constitutes a security agreement and (iii) the Seller and the Purchaser each represents and warrants as to itself only that each remittance of any collections with respect to the Receivables or any other proceeds to the Purchaser, or its assignee, thereof under this Agreement, will have been (A) in payment of a debt incurred by the Seller in the ordinary course of business or financial affairs of the Seller and the Purchaser and (B) made in the ordinary course of business or financial affairs of the Seller and the Purchaser.

(e) At its own expense, on or before the first Series Issuance Date, in the case of the Initial Accounts, and on or before the applicable Addition Date, in the case of Additional Accounts, the Seller has (in the case of the Initial Accounts) or will (to the extent it has not done so):

(i) indicate in its books and records (and with respect to (C) below, in its computer files) that the Receivables arising in connection with the Accounts and the Related Security: (A) have been sold or assigned, as the case may be, to the Purchaser pursuant to this Agreement, then (B) transferred by the Purchaser to the Issuer pursuant to the Transfer and Servicing Agreement and then (C) pledged by the Issuer to the Indenture Trustee for the benefit of the Noteholders pursuant to the Indenture; and

(ii) deliver the Initial Account Schedule and each applicable Additional Account Schedule.

4

The Account Schedule, as amended, supplemented or otherwise modified from time to time will be marked as Schedule I to this Agreement and is hereby incorporated into and made a part of this Agreement.

(f) In consideration for the sale of Receivables indicated on Schedule I hereto on the first Series Issuance Date and the Related Security and other personal property described in Section 2.01(a)(i), the Purchaser has paid to the Seller consideration in the form of cash and other valuable consideration having value reasonably equivalent to the value of the assets so conveyed on such date. The purchase prices for the Receivables, Related Security and other personal property described in Section 2.01(a)(i) or (ii), as applicable, sold pursuant to this Agreement on subsequent Series Issuance Dates and on any other date on which Receivables are sold to the Purchaser by the Seller, will be agreed to by the Purchaser and the Seller at the time of such sales, and will be paid in the form of cash or other valuable consideration having value reasonably equivalent to the value of the assets so conveyed on such date. In each case, the purchase price will not be materially less favorable than prices for transactions of a generally similar character at the time of the acquisition, taking into account the quality of such Receivables, the Seller’s cost of originating such Receivables and a reasonable return on such costs, and other pertinent factors; provided that such consideration will in any event not be less than reasonably equivalent value therefor.

Notwithstanding anything in this Agreement or in the other Basic Documents to the contrary, in originating the Receivables, the Seller acts solely in its individual capacity and not in the capacity of agent or nominee of the Purchaser or the Issuer. In connection with all sales of Receivables by the Seller to the Purchaser under this Agreement, the Seller is under no obligation and does not intend to inform the related Dealers of such sales by the Seller to the Purchaser or the transfer thereof by the Purchaser to the Issuer under the Transfer and Servicing Agreement.

If and to the extent that the Purchaser does not have sufficient funds available to pay to the Seller the purchase price for the Receivables in a transfer hereunder, the amount of the excess of such purchase price over the amount of such available funds shall be considered a contribution of capital from the Seller to the Purchaser.

7

(iv) This Agreement creates a valid and continuing security interest (as defined in the UCC) in the Receivables, Related Security and other personal property described in Section 2.01(a) in favor of the Purchaser, which security interest is prior to all other Liens (other than Permitted Liens), and is enforceable as such as against creditors of and purchasers from the Seller.

(v) The Receivables constitute “instruments”, “chattel paper”, “general intangibles”, “payment intangibles” or “accounts” within the meaning of the UCC.

(viii) The Seller has not authorized the filing of and is not aware of any financing statements against the Seller that include a description of collateral covering the Receivables, Related Security or other personal property described in Section 2.01(a) other than any financing statement (i) relating to the security interest granted to the Purchaser hereunder, (ii) that has been terminated or as to which the secured party has released its security interest with respect to collateral covering the Receivables, Related Security or other personal property described in Section 2.01(a), or (iii) that was filed with respect to Permitted Liens.

In such event, the Seller will pay an amount not less than the Purchase Amount for the repurchase of such Receivable on the Determination Date on which the Purchaser is required to accept reassignment pursuant to the Transfer and Servicing Agreement. The Seller will repurchase such Receivable by making a payment to the Purchaser, in immediately available funds, in an amount equal to the Purchase Amount for such Receivable. Upon payment of such purchase price and reassignment of such Receivables to the Purchaser in accordance with the Transfer and Servicing Agreement, the Purchaser will automatically and without further action be deemed to sell, transfer, assign, set over and otherwise convey to the Seller, without recourse, representation or warranty, all the right, title and interest of the Purchaser in and to such Receivable, all Related Security and all monies due or to become due with respect thereto and all proceeds thereof. The Purchaser will execute such documents and instruments of sale or assignment mutually agreed to by the Purchaser and the Seller. The Purchaser will also take such other actions as are reasonably requested by the Seller to effect the conveyance of such Receivable. The Seller’s obligation to repurchase a Receivable or all the Receivables with respect to an Account pursuant to this Section 2.03(c) constitutes the sole remedy with respect to the event of the type specified in the first sentence of this Section 2.03(c) available to the Purchaser and to the Noteholders (or the Owner Trustee or the Indenture Trustee on behalf of the Noteholders).

(ii) Floorplan Financing Agreements and Guidelines. The Seller will comply with and perform its servicing obligations with respect to the Accounts and the Receivables in conformity with its then-current policies and procedures and in accordance with the applicable Floorplan Financing Agreements relating to the Accounts and the applicable Floorplan Financing Guidelines, except insofar as any failure to so comply or perform would not materially and adversely affect the rights of the Purchaser, the Issuer or the Noteholders. Subject to compliance with all Requirements of Law, the Seller, in its capacity as Servicer, may change the terms and provisions of any Floorplan Financing Agreement or the Floorplan Financing Guidelines in any respect (including the calculation of the amount or the timing of charge-offs and the rate of the finance charge assessed thereon) only if such change would be permitted pursuant to Section 3.01(d) of the Transfer and Servicing Agreement.

9

(E) the addition of the Receivables arising in connection with such Additional Accounts will not, in the reasonable belief of the Seller, cause an Early Amortization Event to occur; and

(v) deliver to the Purchaser an Officer’s Certificate confirming, to the best of such officer’s knowledge, the satisfaction of each of the conditions set forth in clauses (i) through (iv) above. The Purchaser may conclusively rely on such Officer’s Certificate and has no duty to make inquiries with regard to the matters set forth therein and will incur no liability in so relying.

(c) The Seller hereby represents and warrants on each Addition Date as to the matters set forth in clause (iv) of Section 2.05(b). These representations and warranties will survive the sale and assignment of the respective Receivables and the Related Security to the Purchaser. If any Responsible Officer of the Seller or the Purchaser has actual knowledge of a breach of any of the foregoing representations and warranties, the party discovering the breach will give prompt written notice to the other party and the Indenture Trustee. If any such breach has a material adverse effect on the related Receivable, the provisions of Section 2.03(c) will apply.

Section 2.06 Removal of Accounts Without Removal of Receivables.

(a) On each date on which Accounts are redesignated as Redesignated Accounts pursuant to Section 2.07 of the Transfer and Servicing Agreement, the Purchaser shall be deemed to have offered to the Seller automatically and without notice to or action by or on behalf of the Purchaser, the right to remove such Redesignated Accounts from the operation of this Agreement in the manner prescribed in Section 2.06(b). The Seller shall be deemed to have accepted such offer with respect to each Redesignated Account on the related Redesignation Date.

11

(i) not less than five Business Days prior to the Redesignation Date, furnish to the Purchaser, the Servicer (if the Servicer is not GMF), the Indenture Trustee and each Rating Agency a Redesignation Notice specifying the Accounts to be designated as Designated Accounts and the applicable Redesignation Date;

(ii) on or prior to the date that is five Business Days after the Redesignation Date, deliver to the Indenture Trustee a computer file or written list containing a true and complete list of the Redesignated Accounts and specifying for each such Redesignated Account, as of the Redesignation Date, its account number and the aggregate amount of Principal Receivables outstanding in such Redesignated Account;

(iii) from and after the Redesignation Date, cease to transfer to the Purchaser any and all Receivables arising in each such Redesignated Account;

TERMINATION

Section 5.01 Termination of Agreement.

This Agreement will terminate immediately after the legal existence of the Issuer terminates pursuant to the Trust Agreement. In addition, the Purchaser will immediately cease purchasing Receivables and the Seller will immediately cease selling Receivables and will not designate any Additional Accounts if the Seller shall become the subject of any proceeding provided for by any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings of or relating to the Seller or relating to all or substantially all of its property (an “Involuntary Case”) and such Involuntary Case shall have continued for a period of 20 Business Days from and including the day of receipt by the Seller at its principal, corporate office of notice of such Involuntary Case; provided that during such 20 Business Day period, the Purchaser shall suspend its purchase of Receivables and shall hold all Collections of Principal Receivables that would have been available to purchase Receivables in the Collection Account and (a) if by the first Business Day after such 20 Business Day period, neither the Seller nor the Purchaser has obtained an order from the court having jurisdiction of such case or filing which order approves the continuation of the sale of Receivables by the Seller to the Purchaser and which provides that the Seller and any of its transferees (including the Issuer, the Owner Trustee and the Indenture Trustee) may conclusively rely on such order for the validity and non-avoidance of such transfer (the “Order”), the Purchaser shall hold such Collections in the Collection Account until such time as they may be paid as elsewhere provided herein and shall

16

not purchase Receivables thereafter, or (b) if by such first Business Day, the Seller or the Purchaser has obtained such Order, the Seller may continue selling Receivables, and the Purchaser may continue purchasing Receivables, pursuant to the terms hereof, as modified by the immediately succeeding sentence. During the period after the 20 Business Day period described above and before the end of the 60-day period described below, the purchase price of the Receivables transferred during such period, notwithstanding anything in this Agreement to the contrary, shall be paid to the Seller by the Purchaser in cash not later than the same Business Day of any sale of Receivables. During such period, Receivables will be considered transferred to the Purchaser only to the extent that the purchase price therefor has been paid in cash on the same Business Day. If an Order is obtained but subsequently is reversed or rescinded or expires, the Seller shall immediately cease selling Receivables to the Purchaser and the Purchaser shall immediately cease buying Receivables. The Seller shall give prompt written notice to each of the Purchaser, the Owner Trustee, the Indenture Trustee and each Rating Agency immediately upon becoming a party to an Involuntary Case. If by the first Business Day after the 60-day period after such involuntary filing, such Involuntary Case has not been dismissed, the Purchaser shall not thereafter purchase Receivables or designate Additional Accounts for transfer to the Issuer. Notwithstanding any cessation of the sale of Receivables to the Purchaser pursuant to this Section, Receivables sold to the Purchaser prior to the Seller becoming a party to an Insolvency Case and Collections in respect of such Receivables will continue to be property of the Purchaser available for transfer by the Purchaser to the Issuer pursuant to the Transfer and Servicing Agreement.

INTERCREDITOR PROVISIONS

Section 6.01 Nonfloorplan Agreements Between Seller and Dealer.

(a) With respect to any Dealer that is the obligor under Receivables that have been or will be sold to the Purchaser hereunder, the Seller may be or become a lender to such Dealer under a Nonfloorplan Agreement pursuant to which the Seller (either directly, or as assignee of the originator of the Account) has been or may be granted a security interest in Common Collateral, which Common Collateral may include Common Vehicle Collateral.

(b) The Seller hereby agrees that (i) any security interest it now has or may hereafter acquire from time to time in, to or under any and all Common Vehicle Collateral (whether now existing or hereafter arising) shall, without further action by the Seller, the Purchaser or any other Person, at all times be subordinate and junior in priority to any security interest in the Common Vehicle Collateral created from time to time pursuant to the related Floorplan Financing Agreements (and the Seller hereby agrees to take such further actions as the Purchaser, the Issuer or the Indenture Trustee may reasonably request to more fully effectuate such subordination), (ii) it shall not foreclose or otherwise realize upon any Common Vehicle Collateral (except in its capacity as Servicer, acting for the benefit of the Issuer and the Noteholders) or exercise its rights under any Nonfloorplan Agreement (or otherwise) with respect to any Common Vehicle Collateral (including, without limitation, by way of setoff against any deposit or other amount at any time owing by the Seller to the related Dealer), in each case, in any manner that is materially adverse to the Purchaser, the Issuer or the Noteholders, until all scheduled or required payments in respect of the Receivables under the

17

related Floorplan Financing Agreement(s) have been paid in full and (iii) in realizing upon such Common Vehicle Collateral, neither the Purchaser, the Issuer nor the Indenture Trustee has any obligation to notify the Seller or to protect or preserve the rights of the Seller in such Common Vehicle Collateral (and, without limiting the generality of the foregoing, the Purchaser, the Issuer and the Indenture Trustee may liquidate or otherwise deal with the Common Vehicle Collateral as it or they deem appropriate in accordance with the Indenture and the other Basic Documents). The Purchaser agrees that if another creditor of a Dealer has a security interest in any Common Non-Vehicle Collateral, such security interest may be senior to the interest therein of the Purchaser and the Seller has no obligation whatsoever to attempt to remove or challenge or satisfy such other security interest in any manner or to limit in any way the exercise of remedies by such other creditor with respect thereto, and is not responsible for replacing any such Common Non-Vehicle Collateral or for any shortfalls or loss, claims or damages relating to or resulting therefrom whatsoever.

(c) The Purchaser hereby agrees that (i) any security interest it now has or may hereinafter acquire from time to time in, to or under any and all Common Non-Vehicle Collateral (whether now existing or hereafter arising) shall, without further action by the Seller, the Purchaser or any other Person, at all times be subordinate and junior in priority to any security interest in the Common Non-Vehicle Collateral created from time to time pursuant to the related Nonfloorplan Agreements (and the Purchaser hereby agrees to take such further actions as the Seller may reasonably request to more fully effectuate such subordination), (ii) it shall not foreclose or otherwise realize upon any Common Non-Vehicle Collateral or exercise its rights under any Floorplan Financing Agreement (or otherwise) with respect to any Common Non-Vehicle Collateral, in each case, in any manner that is materially adverse to the Seller, until all scheduled or required payments in respect of the obligations created or secured by the Nonfloorplan Agreement(s) have been paid in full and (iii) in realizing on such Common Non-Vehicle Collateral, the Seller has no obligation to notify the Purchaser, the Issuer or the Indenture Trustee or to protect or preserve the rights of the Purchaser, the Issuer or the Indenture Trustee in such Common Non-Vehicle Collateral (and, without limiting the generality of the foregoing, the Seller may liquidate or otherwise deal with the Common Non-Vehicle Collateral as it deems appropriate). The Transfer and Servicing Agreement will provide that the Issuer is subject to the preceding sentence.

(d) If the Seller in any manner assigns or transfers any rights under, or any obligation evidenced or secured by, a Nonfloorplan Agreement, the Seller will make such assignment or transfer subject to the provisions of this Article VI and require such assignee or transferee to acknowledge that it takes such assignment or transfer subject to the provisions of this Article VI and to agree that it will require the same acknowledgment from any subsequent assignee or transferee.

Section 7.01 Amendment.

(a) This Agreement may be amended from time to time by the Seller and the Purchaser without the consent of any Noteholder and with notice to each Rating Agency; provided, however, that such amendment does not adversely affect in any material respect the interests of any Noteholder. The absence of any material adverse effect may be evidenced by an Officer’s Certificate of the Seller or the Purchaser delivered to the Issuer and the Indenture Trustee, to the effect that, in the reasonable belief of the Seller or the Purchaser, as applicable, such amendment will not adversely affect in any material respect the interests of any Noteholder.

(b) This Agreement may also be amended from time to time by the Purchaser and the Seller with notice to each Rating Agency and the consent of the Majority Noteholders of all materially adversely affected Series, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Purchaser or the Noteholders; provided, however, that no such amendment may (i) reduce in any manner the amount of or delay the timing of any distributions to be made to Noteholders or deposits of amounts to be so distributed without the consent of each affected Noteholder (provided that changes in Early Amortization Events that decrease the likelihood of the occurrence of those events will not be considered delays in the timing of distributions for purposes of this clause) or (ii) reduce the aforesaid percentage required to consent to any such amendment without the consent of each Noteholder. Any amendment to be effected pursuant to this paragraph will be deemed to materially adversely affect all outstanding Series, other than any Series with respect to which such action will not, as evidenced by an Officer’s Certificate of the Seller, addressed and delivered to the Issuer and the Indenture Trustee, adversely affect in any material respect the interests of any Noteholder of such Series.

(c) Promptly after the execution of any such amendment or consent (other than an amendment pursuant to paragraph (a)), the Seller will furnish notification of the substance of such amendment to the Indenture Trustee.

(d) If the Noteholders are required to consent to any proposed amendments pursuant to this Section, such Noteholders need not consent to or approve the particular form of such amendment.

(c) The Seller will give the Purchaser and the Indenture Trustee prompt written notice of any (i) relocation of any office at which it keeps records concerning the Receivables or of its principal executive office and (ii) change in the Seller’s jurisdiction of organization and whether, as a result of such relocation or change, 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 and will file such financing statements or amendments as may be necessary to perfect or to continue the perfection of the Purchaser’s security interest in the Receivables and the proceeds thereof.
