In consideration of the sale on the Closing Date of $860,601,737 in Contract Balance of Receivables as of the Cut-off Date, the Purchaser shall deliver to or upon the order of the Seller cash in an amount of $850,074,872. The Seller does hereby sell, transfer, assign, set over and otherwise convey to the Purchaser, without recourse (subject to the obligations herein), all right, title and interest in and to the following, whether now owned or hereafter acquired:

     (a) all right, title and interest of the Seller in and to the Receivables, and all monies (including accrued interest) due thereunder on or after the Cut-off Date;

     (b) the interests of the Seller in the security interests in the Transaction Equipment granted by Obligors pursuant to the Receivables and any other interest of the Seller in such Transaction Equipment, including any Liquidation Proceeds;

     (c) the interest and rights of the Seller in any proceeds with respect to the Receivables from claims on any physical damage, credit life, liability or disability insurance policies covering Financed Equipment or Obligors, as the case may be;

     (d) the interest of the Seller in any proceeds of repossessed or returned Transaction Equipment;

     (e) the interest of the Seller in any proceeds from recourse to, or other payments by, Dealers on Receivables; and

     (f) the proceeds of any and all of the foregoing.

     It is the express intent of the parties hereto that the conveyance of the Receivables and the other property described above by the Seller to the Purchaser as provided in this Agreement be, and be construed as, a sale of the Receivables by the Seller to the Purchaser. It is, further, not the intention of the parties that such conveyance be deemed a pledge of the Receivables or the other property described above by the Seller to the Purchaser to secure a debt or other obligation of the Seller. However, in the event, notwithstanding the intent of the parties, the Receivables or the other property described above are held to be property of the Seller, or if for any reason this Agreement is held or deemed to create a security interest in the Receivables or the other property described above then, (a) this Agreement shall be a security agreement within the meaning of Article 9 of the New York UCC; and (b) the Seller 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 and to the property described in clauses (a) through (f) above, in order to secure the obligations of the Seller hereunder. In connection herewith, the Purchaser (or its assignee) shall have all of the rights and remedies of a secured party and creditor under the UCC.

4

     Any assignment of the interest of the Purchaser pursuant to this Section 2.01 shall also be an assignment of the security interest created hereby. The Seller and the Purchaser shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement creates a security interest in the Receivables, such security interest would be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement.

     SECTION 2.02. Ownership and Custody of Receivables Files.

     (a) Upon the acceptance by the Seller of the amount set forth in Section 2.01, the ownership of each Receivable and the contents of the related Receivables File shall be vested in the Purchaser.

     (b) In connection with the sale of the Receivables pursuant to Section 2.01, within 30 days of the Closing Date, the Seller shall deliver each Receivable File to the Custodian on behalf of the Purchaser.

     SECTION 2.03. Books and Records.

     The transfer of each Receivable shall be reflected on the Seller’s balance sheets and other financial statements prepared in accordance with generally accepted accounting principles as a sale of assets by the Seller to the Purchaser. The Seller shall be responsible for maintaining, and shall maintain, a complete and accurate set of accounts, records and computer files for each Receivable which shall be clearly marked to reflect the ownership of each Receivable by the Purchaser.

     SECTION 2.04. Custody of Receivable Files. Pursuant to the Custodial Agreement the Purchaser has appointed the Custodian, and the Custodian accepted such appointment, to act as custodian of the Receivables Files.

     SECTION 2.05. Certifications by the Servicer and the Custodian.

     (a) In accordance with the terms of the Sale and Servicing Agreement, the Servicer will review the Receivable Files and deliver the certification required by Section 3.05(a) of the Sale and Servicing Agreement.

     (b) In accordance with the terms of the Custodial Agreement, the Custodian will review each of the Receivable Files and deliver the certifications or notices required by to Sections 3.1 and 4.1 of the Custodial Agreement. It is understood that the scope of the Custodian’s review of the Receivable Files is limited solely to confirming that it has received each Receivable File. The Seller agrees to use reasonable efforts to cause to be delivered to the Custodian any Receivable File that the Custodian determines is missing and to cause to be remedied a material defect in a document constituting part of a Receivables File. If, however, within 60 days after it has delivered the Receivable Files to the Custodian (A) the Seller has not caused such missing Receivable File to be delivered or (B) the Seller has not caused to be remedied any such material defect, and such defect materially and adversely affects the interest of the Purchaser in the related Receivable, the Seller shall remit the Purchase Amount with respect to such Receivable

5

to the Purchaser. The sole remedy of the Purchaser, the Trust, the Owner Trustee, the Indenture Trustee, the Noteholders or the Certificateholder with respect to a breach shall be to require the Seller to repurchase Receivables pursuant to this Section, subject to the conditions contained herein. The Owner Trustee shall have no duty to conduct any affirmative investigation as to the occurrence of any condition requiring the repurchase of any Receivable pursuant to this Section.

     SECTION 2.06. The Closing.

     The conveyance of the Receivables and the other property described in Section 2.01 shall take place on the Closing Date, simultaneously with the closing of the transactions contemplated by the Sale and Servicing Agreement, the Indenture, the underwriting agreements related to the Notes and the other Basic Documents.

     (b) The Seller makes the following representations and warranties as to the Receivables on which the Purchaser relied in accepting the Receivables. The parties hereto acknowledge that the representations and warranties below require the Seller to monitor conditions that it may not have the ability to monitor. Accordingly, wherever the Seller makes, or is deemed to make, a representation that it cannot monitor, such representation shall be made as if prefaced with the phrase “to the best of the Seller’s knowledge”; provided, however, that the determination as to whether a Repurchase Event has occurred pursuant to Section 6.02 shall be made without reliance on whether the Seller actually had knowledge of the accuracy of any of its representations. Such representations and warranties speak as of the execution and delivery of this Agreement but shall survive the sale, transfer and assignment of the Receivables to the Purchaser and the subsequent assignments and transfers of the Receivables pursuant to the Sale and Servicing Agreement and the Indenture:

     (i) Characteristics of Receivables. Each Receivable (A) was originated in the United States of America by the Seller in the ordinary course of business or was originated by a Dealer in the ordinary course of business, in each case in connection with the retail sale by a Dealer of Financed Equipment in the ordinary course of such Dealer’s business, was fully and properly executed by the parties thereto, and if originated by such Dealer, was purchased by the Seller from such Dealer and was validly assigned by such Dealer to the Seller in accordance with its terms, (B) has created a valid, subsisting and enforceable (subject to paragraph (iv) below) first priority security interest in favor of the Seller in the

8

Financed Equipment, and if applicable, a valid, subsisting and enforceable (subject to paragraph (iv) below) security interest in favor of the Seller in the Cross-Collateralized Equipment, which security interests are assignable by the Seller to the Purchaser, by the Purchaser to the Trust and by the Trust to the Indenture Trustee, (C) contains customary and enforceable (subject to paragraph (iv) below) provisions such that the rights and remedies of the holder thereof are adequate for realization against the collateral of the benefits of the security and (D) provides for fixed payments (except as described below) on a periodic basis, yields interest at a fixed-rate (in the case of Receivables related to an Installment Sales Contract) and is prepayable without premium or penalty at any time. The fixed payments provided for are sufficient to amortize the Amount Financed of such Receivable by maturity and yield interest at the APR.

     (ii) Schedule of Receivables. The information set forth in the Schedule of Receivables to this Agreement is true and correct in all material respects as of the opening of business on the Cut-off Date and no selection procedures believed to be adverse to the Noteholders or the Certificateholder were utilized in selecting the Receivables.

Each Receivable and the sale or lease of the Financed Equipment complied at the time it was originated or made, and at the execution of this Agreement complies in all material respects, with all requirements of applicable federal, state and local laws and regulations thereunder, including usury laws, the Federal Truth-in-Lending Act, the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Fair Debt Collection Practices Act, the Federal Trade Commission Act, the Magnuson-Moss Warranty Act, the Federal Reserve Board’s Regulations B and S and other equal credit opportunity and disclosure laws.

Such enforceability has not been and is not adversely affected by whether or not the Seller was or is qualified to do business in the state in which the Obligor was or is located.

     (v) Security Interest in Financed Equipment. Immediately prior to the sale, assignment and transfer thereof, each Receivable shall be secured by a validly perfected first priority security interest in the Financed Equipment in favor of the Seller as secured party. As of the Cut-off Date, such Financed Equipment is located in the United States of America.

     (vi) Receivables in Force. No Receivable has been satisfied, subordinated or rescinded and no Financed Equipment been released from the lien granted by the related Receivable in whole or in part.

     (xii) Insurance. Each Obligor is required to obtain and maintain physical damage insurance and/or liability insurance, as applicable, covering the Financed Equipment in accordance with the Seller’s normal requirements.

     (xiii) Title. It is the intention of the Seller that the transfer and assignment herein contemplated constitute a sale of the Receivables from the Seller to the Purchaser, and that the beneficial interest in and title to the Receivables not be part of the debtor’s estate in the event of the filing of a bankruptcy petition by or against the Seller under any bankruptcy law.

     (xvii) Maturity of Receivables. Each Receivable has a final scheduled payment date due not later than the payment date occurring in March 2010 as of the Cut-off Date and the weighted average remaining term of the Receivables is 44 months as of the Cut-off Date.
