(v) No Government Obligor. No Receivable is due from the United States or any State or from any agency, department or instrumentality of the United States or any State.

(vi) Security Interest in Financed Vehicles. Immediately prior to the transfer of the Receivables by the Seller to the Depositor, each Receivable was secured by a valid, binding and enforceable first priority perfected security interest in favor of the Seller in the related Financed Vehicle, which security interest has been validly assigned by the Seller to the Depositor.

Except for payment defaults continuing for a period of not more than 30 days, the Seller has no knowledge that any default, breach, violation or event permitting acceleration under the terms of any Receivable has occurred or that any continuing condition that with notice or the lapse of time or both would constitute a default, breach, violation or event permitting acceleration under the terms of any Receivable has arisen, and the Seller has not waived any such event or condition.

(xii) Title. The Seller intends that the transfer of the Receivables contemplated by Section 2.1 constitute a sale of the Receivables from the Seller to the Depositor and that the beneficial interest in, and title to, the Receivables not be part of the Seller's estate in the event of the filing of a bankruptcy petition by or against the Seller under any bankruptcy law. The Seller has not sold, transferred, assigned or pledged any Receivable to any Person other than the Depositor. Immediately prior to the transfer of the Receivables contemplated by Section 2.1, the Seller had good and marketable title to the Receivables free and clear of any Lien, claim or encumbrance of any Person and, immediately upon such transfer, the Depositor shall have good and marketable title to the Receivables free and clear of any Lien, claim or encumbrance of any Person.

The motor vehicle retail installment sale contracts that constitute or evidence the Receivables do not have any marks or notations indicating that they have been pledged, assigned or otherwise conveyed to any Person other than the Depositor, the Issuer or the Indenture Trustee. The Seller is not aware of any judgment or tax lien filings against the Seller.

(xiv) Financing Statements. All financing statements filed or to be filed against the Seller in favor of the Indenture Trustee (as assignee of the Depositor and the Issuer) contain a statement substantially to the following effect: “A purchase of or security interest in any collateral described in this financing statement will violate the rights of the Indenture Trustee.”

(xv) Valid Assignment. No Receivable has been originated in, or is subject to the laws of, any jurisdiction under which the sale, transfer, assignment and conveyance of such Receivable under this Agreement or the Sale and Servicing Agreement or the pledge of such Receivable under the Indenture is unlawful, void or voidable or under which such Receivable would be rendered void or voidable as a result of any such sale, transfer, assignment, conveyance or pledge.
