REPURCHASES

SECTION V.1 Repurchase of Receivables Upon Breach of Warranty. Upon (a) the discovery by the Depositor, the Servicer or the Issuer, or (b) the receipt of written notice by or actual knowledge of a Responsible Officer of the Indenture Trustee or Backup Servicer, of the occurrence of a Repurchase Event, the Seller shall, unless the breach which is the subject of such Repurchase Event shall have been cured in all material respects using commercially reasonable efforts, repurchase the Receivable(s) and the Other Conveyed Property relating thereto from the Issuer if the interest of the Noteholders in such Receivable and the Other Conveyed Property is materially and adversely affected by any such breach and, simultaneously with the repurchase of such Receivable and the related Other Conveyed Property, the Seller shall deposit the Purchase Amount in full, without deduction or offset, to the Collection Account, pursuant to Section 5.6 of the Sale and Servicing Agreement. It is understood and agreed that, except as set forth in this Section 5.1, the obligation of the Seller to repurchase any Receivable and the related Other Conveyed Property as to which a breach occurred and is continuing, shall, if such obligation is fulfilled, constitute the sole remedy against the Seller for such breach available to the Purchaser, the Issuer, the Backup Servicer, the Noteholders, the Certificateholders, the Indenture Trustee on behalf of the Noteholders or the Owner Trustee on behalf of the Certificateholders. The provisions of this Section 5.1 are intended to grant the Issuer a direct right against the Seller to demand performance hereunder, and in connection therewith, the Seller waives any requirement of prior demand against the Purchaser with respect to such repurchase obligation. Any such repurchase shall take place in the manner specified in Section 3.3 of the Sale and Servicing Agreement.

Notwithstanding any other provision of this Agreement or the Sale and Servicing Agreement to the contrary, the obligation of the Seller under this Section shall not terminate upon a termination of the Seller as Servicer under the Sale and Servicing Agreement and shall be performed in accordance with the terms hereof notwithstanding the failure of the Servicer or the Purchaser to perform any of their respective obligations with respect to such Receivable under the Sale and Servicing Agreement. Notwithstanding anything in this Agreement to the contrary, the Indenture Trustee shall have no duty to ensure the eligibility of any Receivable for purposes of this Agreement or to enforce the repurchase obligations of the Seller.

In addition to the foregoing and notwithstanding whether the related Receivable shall have been repurchased by the Seller, the Seller shall indemnify the Issuer, the Indenture Trustee, the Backup Servicer, the Owner Trustee, the Noteholders and the Certificateholders from and against all costs, expenses, losses, damages, claims and liabilities, including reasonable fees and expenses of counsel and court costs (including those incurred in connection with any enforcement (including any action, claim or suit brought) by the Owner Trustee, Indenture Trustee or Backup Servicer of any indemnification or other obligation of the Seller), which may be asserted against or incurred by any of them arising out of the events or facts giving rise to such Repurchase Events. In the event the Seller fails to provide such indemnity payments due pursuant to this Section to the Owner Trustee, Indenture Trustee or Backup Servicer, the Owner Trustee, Indenture Trustee and Backup Servicer shall collect such indemnity amounts pursuant to Section 7.2 of the Trust Agreement (with respect to the Owner Trustee), Section 5.7(b) of the Sale and Servicing Agreement or Section 5.6 of the Indenture. The indemnity obligations hereunder shall survive any termination or assignment of this Agreement, or the resignation or removal of any party, and shall be in addition to any obligation that the Seller may otherwise have.

SECTION V.2 Reassignment of Purchased Receivables. Upon deposit in the Collection Account of the Purchase Amount of any Receivable repurchased by the Seller under Section 5.1 of this Agreement, the Purchaser shall, without further action, be deemed to 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, to and under such repurchased Receivable, all other related Other Conveyed Property and all monies due or to become due with respect thereto and all proceeds thereof, and the Purchaser and the Issuer (pursuant to Section 3.3 of the Sale and Servicing Agreement) shall take such steps as may be reasonably requested by the Seller in order to assign to the Seller all of the Purchaser's right, title and interest in and to such Receivable and all security and documents and all Other Conveyed Property conveyed to the Purchaser directly relating thereto, without recourse, representation or warranty, except as to the absence of Liens created by or arising as a result of actions of the Purchaser or the Issuer. Such assignment shall be a sale and assignment outright, and not for security. If, following the reassignment of a Purchased Receivable, in any enforcement suit or legal proceeding, it is held that the Seller may not enforce any such Receivable on the ground that it shall not be a real party in interest or a holder entitled to enforce the Receivable, the Purchaser shall, at the expense of the Seller, take such steps as the Seller deems reasonably necessary to enforce the Receivable, including bringing suit in the Purchaser's name.

SECTION V.3 Waivers. No failure or delay on the part of the Purchaser, or the Issuer as assignee of the Purchaser, or the Indenture Trustee as assignee of the Issuer, in exercising any power, right or remedy under this Agreement shall operate as a waiver thereof, nor shall any single

or partial exercise of any such power, right or remedy preclude any other or future exercise thereof or the exercise of any other power, right or remedy.

Immediately prior to the conveyance of the Receivables to the Issuer pursuant to this Agreement, the Purchaser was the sole owner thereof and had good and indefeasible title thereto, free of any Lien and, upon execution and delivery of this Agreement by the Purchaser, the Issuer shall have good and indefeasible title to and will be the sole owner of such Receivables, free of any Lien. No Dealer has a participation in, or other right to receive, proceeds of any Receivable. The Purchaser has not taken any action to convey any right to any Person that would result in such Person having a right to payments received under the related Insurance Policies or the related Dealer Agreements or Dealer Assignments or to payments due under such Receivables.

19. Security Interest in Financed Vehicle. Each Receivable created or shall create a valid, binding and enforceable first priority security interest in favor of Seller (or an Originating Affiliate which first priority security interest has been assigned to Seller) in the Financed Vehicle. The Lien Certificate for each Financed Vehicle shows, or if a new or replacement Lien Certificate is being applied for with respect to such Financed Vehicle the Lien Certificate will be received within 180 days of the origination date of the related Receivable and will show, Seller (or an Originating Affiliate) named as the original secured party under each Receivable as the holder of a first priority security interest in such Financed Vehicle. With respect to each Receivable for which the Lien Certificate has not yet been returned from the Registrar of Titles, Seller or the related Originating Affiliate has applied for or received written evidence from the related Dealer that such Lien Certificate showing Seller, an Originating Affiliate or the Issuer, as applicable, as first lienholder has been applied for and the Originating Affiliate's security interest has been validly assigned by the Originating Affiliate to Seller and Seller's security interest (assigned by Seller to the Purchaser pursuant to the Purchase Agreement) has been validly assigned by the Purchaser to the Issuer pursuant to the Sale and Servicing Agreement. The Sale and Servicing Agreement creates a valid and continuing security interest (as defined in the UCC) in the Receivables in favor of the Issuer, which security interest is prior to all other Liens, and is enforceable as such against creditors of and purchasers from the Purchaser. Immediately after the sale, transfer and assignment by the Purchaser

to the Issuer, each Receivable will be secured by an enforceable and perfected first priority security interest in the Financed Vehicle in favor of the Indenture Trustee as secured party, which security interest is prior to all other Liens upon and security interests in such Financed Vehicle which now exist or may hereafter arise or be created (except, as to priority, for any lien for taxes, labor or materials affecting a Financed Vehicle).

Other than the security interest granted to the Purchaser pursuant to this Agreement and except any other security interests that have been fully released and discharged as of the Closing Date, the Seller has not pledged, assigned, sold, granted a security interest in or otherwise conveyed any of the Receivables. 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 other than any financing statement relating to the security interest granted to the Purchaser hereunder or that has been terminated. The Seller is not aware of any judgment or tax lien filings against it.

23. Receivable Not Assumable. No Receivable is assumable by another Person in a manner which would release the Obligor thereof from such Obligor's obligations to the owner thereof with respect to such Receivable.

24. No Defenses. No Receivable is subject to any right of rescission, setoff, counterclaim or defense and no such right has been asserted or threatened with respect to any Receivable.
