4

(e) Security Interest in Financed Vehicle. Immediately prior to the sale, transfer and assignment thereof pursuant hereto and the First Step Receivables Assignment, each Receivable was secured by a validly perfected first priority security interest in the Financed Vehicle in favor of the Seller as secured party or all necessary and appropriate action had been commenced that would result in the valid perfection of a first priority security interest in the Financed Vehicle in favor of the Seller as secured party.

(f) Receivables In Force. Each such Receivable has not been satisfied, subordinated or rescinded, and the Financed Vehicle securing each such Receivable has not been released from the lien of the related Receivable in whole or in part.

(g) No Waiver.

(k) One Original. There is only one original executed copy (or with respect to “electronic chattel paper,” one authoritative copy) of each such Receivable.

(l) No Documents or Instruments. No such Receivable, or constituent part thereof, constitutes a “negotiable instrument” or “negotiable document of title” (as such terms are used in the UCC).

The Seller makes the following representations and warranties as to the pool of Receivables, on which Ally Auto relies in accepting the Receivables.

(d) Lawful Assignment. Each such Receivable was not originated in, or is not subject to the laws of, any jurisdiction the laws of which would make unlawful the sale, transfer and assignment of each such Receivable under this Agreement, the Trust Sale Agreement or the Indenture, as applicable.

SECTION 4.03 Other Liens or Interests. Except for the conveyances hereunder and under the First Step Receivables Assignment and as contemplated by the Further Transfer Agreements, the Seller shall not sell, pledge, assign or transfer the Receivables or other Purchased Property to any other Person, or grant, create, incur, assume or suffer to exist any Lien on any interest therein, and the Seller shall defend the right, title and interest of Ally Auto in, to and under such Receivables or other Purchased Property against all claims of third parties claiming through or under the Seller.
