         pursuant to the terms of, any indenture, mortgage, deed of trust, loan
         agreement, guarantee, lease financing agreement or similar agreement or
         instrument under which the Seller is a debtor or guarantor, nor will

transfer pursuant to the Sale and Servicing Agreement:

                           (i) Characteristics of Receivables. Each Receivable
         (a) has been originated in the United States of America by a Dealer for
         the retail sale of a Financed Vehicle in the ordinary course of such
         Dealer's business, has been fully and properly executed by the parties
         thereto, has been purchased by the Seller from such Dealer under an
         existing dealer agreement with the Seller, and has been validly
         assigned by such Dealer to the Seller, (b) created a valid, subsisting
         and enforceable security interest in favor of the Seller in such
         Financed Vehicle, (c) contains customary and enforceable provisions
         such that the rights and remedies of the holder thereof are adequate
         for realization against the collateral of the benefits of the security,
         (d) provides for level monthly payments (provided that the payment in
         the first or last month in the life of the Receivable may be minimally
         different from the level payment) that fully amortize the Amount
         Financed over an original term of no greater than [____] months, and
         (e) provides for interest at the related Annual Percentage Rate.

                           (ii) Schedule of Receivables. The information set
         forth in Schedule A to this Agreement was true and correct in all
         material respects as of the opening of business on the Cutoff Date; the
         Receivables were selected from the Seller's retail installment sale
         contracts (other than contracts originated in Alabama [, Hawaii or
         Maine]) meeting the criteria of the Trust set forth in the Sale and
         Servicing Agreement; and no selection procedures believed to be adverse
         to the Securityholders were utilized in selecting the Receivables.

<PAGE>


                           (iii) Compliance with Law. Each Receivable, the
         origination of such Receivable, and the sale of the Financed Vehicle
         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 Servicemembers Civil Relief Act, the
         Federal Reserve Board's Regulations B and Z, the Gramm-Leach-Bliley
         Act, and state adaptations of the National Consumer Credit Protection
         Act and of the Uniform Consumer Credit Code, state "Lemon Laws"
         designed to prevent fraud in the sale of automobiles and other consumer
         credit laws and equal credit opportunity and disclosure laws.

                           (iv) Binding Obligation. Each Receivable represents
         the genuine, legal, valid and binding payment obligation in writing of
         the Obligor, enforceable by the holder thereof in accordance with its
         terms, subject to the effect of bankruptcy, insolvency, reorganization,
         moratorium or other similar laws affecting creditors' rights generally
         and by general equitable principles.

                           (v) Security Interest in Financed Vehicle. (a)
         Immediately prior to the sale, assignment and transfer thereof to the
         Purchaser, 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 or all appropriate actions
         shall have 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, and (b) as of the Cutoff Date, according
         to the records of the Seller, no Financed Vehicle has been repossessed
         and the possession thereof not reinstated.

                           (vi) Receivables in Force. No Receivable has been
         satisfied, subordinated or rescinded, nor has any Financed Vehicle been
         released from the lien granted by the related Receivable in whole or in
         part.

                           (vii) No Waiver. No provision of a Receivable has
         been waived in such a manner that is prohibited by the provisions of
         the Sale and Servicing Agreement or that would cause such Receivable to
         fail to meet all of the other requirements and warranties made by the
         Seller herein with respect thereto.

                           (viii) No Defenses. No Receivable is subject to any
         right of rescission, setoff, counterclaim or defense, including the
         defense of usury, and the operation of any of the terms of any
         Receivable, or the exercise of any right thereunder, will not render
         such Receivable unenforceable in whole or in part or subject such
         Receivable to any right of rescission, setoff, counterclaim or defense,
         including the defense of usury, and no such right of rescission,
         setoff, counterclaim or defense has been asserted with respect thereto.


                                       7                   (Purchase Agreement)
<PAGE>

                           (ix) No Liens. To the Seller's knowledge, no liens
         have been filed for work, labor or materials relating to a Financed
         Vehicle that shall be liens prior to, or equal or coordinate with, the
         security interest in the Financed Vehicle granted by the Receivable.

                           (x) No Default. Except for payment defaults
         continuing for a period of not more than 29 days as of the Cutoff Date,
         no default, breach, violation or event permitting acceleration under
         the terms of any Receivable has occurred; and no continuing condition
         that with notice or the lapse of time would constitute a default,
         breach, violation or event permitting acceleration under the terms of
         any Receivable has arisen (other than deferrals and waivers of late
         payment charges or fees permitted under the Sale and Servicing
         Agreement).

                           (xi) Insurance. The Seller, in accordance with its
         customary procedures, has determined at the time of origination of each
         Receivable that the related Obligor has agreed to obtain physical
         damage insurance covering the Financed Vehicle and the Obligor is
         required under the terms of related Receivable to maintain such
         insurance.

                           (xii) 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
         Seller's estate in the event of the filing of a bankruptcy petition by
         or against the Seller under any bankruptcy law. Immediately prior to
         the transfer and assignment herein contemplated, the Seller had good
         and marketable title to each Receivable free and clear of all Liens
         and, immediately upon the transfer thereof, the Purchaser shall have
         good and marketable title to each Receivable, free and clear of all
         Liens and rights of others. Each Receivable File contains the original
         certificate of title (or a photocopy or image thereof) or evidence that
         an application for a certificate of title has been filed. To the extent
         that the transfer and assignment contemplated by this Agreement is
         deemed to be other than a sale, this Agreement and all filings
         described under this Agreement creates a valid and continuing security
         interest (as defined in the applicable UCC) in the Receivables in favor
         of the Purchaser, which security interest is prior to all other Liens,
         and is enforceable as such against creditors of and purchasers from the
         Seller.

                           (xiii) Lawful Assignment. No Receivable has been
         originated in, or shall be subject to the laws of, any jurisdiction
         under which the sale, transfer and assignment of such Receivable under
         this Agreement or pursuant to the Sale and Servicing Agreement are
         unlawful, void or voidable.

                           (xiv) All Filings Made. All actions have been taken,

principal executive office within the United States of America.

                  (d) The Seller shall maintain its computer systems so that,

and duties under this Agreement.

Purchaser from and against all Damages arising out of or incurred in connection
with the acceptance or performance of the Seller's trusts and duties as Servicer
under the Sale and Servicing Agreement, except to the extent that such Damages

Purchaser.

obligation that the Seller may otherwise have.

                  (f) Promptly after receipt by a party indemnified under this

action, such Indemnified Party will, if a claim in respect thereof is to be made
against the Seller under this Section 5.4, notify the Seller of the commencement
thereof. If any such action is brought against any Indemnified Party under this
Section 5.4 and it notifies the Seller of the commencement thereof, the Seller
will assume the defense thereof, with counsel reasonably satisfactory to such
Indemnified Party (who may, unless there is, as evidenced by an opinion of
counsel to the Indemnified Party stating that there is an unwaivable conflict of
interest, be counsel to the Indemnifying Party), and the Seller will not be
liable to such Indemnified Party under this Section 5.4 for any legal or other
expenses subsequently incurred by such Indemnified Party in connection with the
defense thereof, other than reasonable costs of investigation. The obligations
set forth in this Section 5.4 shall survive the termination of this Agreement
and shall include reasonable fees and expenses of counsel and expenses of
litigation. If the Seller shall have made any indemnity payments pursuant to
this Section 5.4 and the Person to or on behalf of whom such payments are made
thereafter collects any of such amounts from others, such Person shall promptly
repay such amounts to the Seller, without interest (except to the extent
received by such Person).

agrees with the Purchaser for the benefit of the Purchaser, the Trust, the
Indenture Trustee and the holders of the Securities, that the occurrence of a

Sale and Servicing Agreement, at the amount of the Warranty Purchase Payment

Purchaser; provided, however, that any such amendment must be consented to by
the [Holders of Notes representing a majority of the Outstanding Amount of the

remedy. Notwithstanding anything to the contrary, the Purchaser shall not waive
any breach of representations and warranties set forth in Sections 3.2(b)(v),
(xii), (xiv), (xv), (xxx) or (xxxi).
