not be part of Seller's estate in the event of the filing of a bankruptcy
petition or insolvency proceeding by or against Seller under any bankruptcy or
insolvency law. No Receivable has been sold, transferred, assigned, or pledged
by Seller to any Person other than Purchaser. Immediately prior to the transfer
and assignment herein contemplated, Seller had good and marketable title to the
Receivable free and clear of any Lien and had full right and power to transfer
and assign the Receivable to Purchaser and, immediately upon the transfer and
assignment of the Receivable to Purchaser, Purchaser shall have good and
marketable title to the Receivable, free and clear of any Lien; and Purchaser's
interest in the Receivable resulting from the transfer has been perfected under
the UCC.

be fulfilled under, or in connection with, the Receivable.

      (m) Possession. There is only one original executed Receivable, and
immediately prior to the Closing Date, the Seller will have possession of such
original executed Receivable.

      (n) [No Government Obligor. The Obligor on the Receivable is not the
United States of America or any state thereof or any local government, or any
agency, department, political subdivision or instrumentality of the United
States of America or any state thereof or any local government.]

      (o) Marking Records. By the Closing Date, Seller shall have caused the
portions of Seller's electronic master record of Motor Vehicle Loans relating to
the Receivables to be clearly and unambiguously marked to show that the
Receivable is owned by Purchaser in accordance with the terms of this Agreement.

      (p) No Assignment. As of the Closing Date, Seller shall not have taken any
action to convey any right to any Person that would result in such Person having
a right to payments received under the Insurance Policies or Dealer Agreements,
or payments due under the Receivable, that is senior to, or equal with, that of
Purchaser.

      (q) Lawful Assignment. The Receivable has not been originated in, and is
not subject to the laws of, any jurisdiction under which the sale, transfer or
assignment of such Receivable


                                       6
<PAGE>
hereunder or pursuant to transfers of the Notes or Certificates are unlawful,
void or voidable. Seller has not entered into any agreement with any Obligor
that prohibits, restricts or conditions the assignment of any portion of the
Receivables.

      (r) Dealer Agreements. A Dealer Agreement for each Receivable is in effect
whereby the Dealer warrants title to the Motor Vehicle and indemnifies the
Seller against the unenforceability of each Receivable sold thereunder, and the
rights of Seller thereunder, with regard to the Receivable sold hereunder, have
been validly assigned to and are enforceable against the Dealer by the
Purchaser, along with any Dealer Recourse.

      (s) Composition of Receivable. No Receivable has a Principal Balance which
includes capitalized interest or late charges.

      (t) Database File. The information included with respect to each
Receivable in the database file delivered pursuant to [Section 4.9(b)] of the
Sale and Servicing Agreement is accurate and complete in all material respects.

      SECTION 3.3. Repurchase upon Breach. Seller or Purchaser, as the case may
be, shall inform the other party to this Agreement promptly, in writing, upon
the discovery of any breach or failure to be true of the representations or
warranties made by Seller in Section 3.2; provided that the failure to give such
notice shall not affect any obligation of Seller. If the breach or failure shall
not have been cured by the last day of the Collection Period which includes the
60th day (or, if Seller elects, the 30th day) after the date on which Seller
becomes aware of, or receives written notice from Purchaser of, such breach or
failure, and such breach or failure materially and adversely affects the
interests of Issuer and the Holders in any Receivable, Seller shall repurchase
each such Receivable from Purchaser as of such last day of such Collection
Period at a purchase price equal to the Purchase Amount for such Receivable as
of such last day of such Collection Period. Notwithstanding the foregoing, any
such breach or failure with respect to the representations and warranties
contained in Section 3.2 will not be deemed to have such a material and adverse
effect with respect to a Receivable if the facts resulting in such breach or
failure do not affect the ability of Issuer to receive and retain payment in
full on such Receivable. In consideration of the purchase of a Receivable
hereunder, Seller shall (unless otherwise directed by Purchaser in writing)
deposit the Purchase Amount of such Receivable, no later than the close of
business on the next Deposit Date, in the Collection Account. The sole remedy of
Purchaser with respect to a breach or failure to be true of the representations
and warranties made by Seller pursuant to Section 3.2 shall be to require Seller
to repurchase Receivables pursuant to this Section 3.3.

                                   ARTICLE IV

                               COVENANTS OF SELLER

<PAGE>
interest of Purchaser, Owner Trustee and Indenture Trustee in the Receivables
and the proceeds thereof. Seller shall deliver (or cause to be delivered) to
Purchaser file-stamped copies of, or filing receipts for, any document filed as
provided above, as soon as available following such filing.

      (b) Seller shall not change its name, identity or corporate structure in
any manner that would, could or might make any financing statement or
continuation statement filed in accordance with paragraph (a) above seriously
misleading within the meaning of Section 9-507 of the UCC, unless it shall have
given Purchaser, Owner Trustee and Indenture Trustee at least five days' prior
written notice thereof and shall have promptly filed appropriate amendments to
all previously filed financing statements or continuation statements.

      (c) Seller shall give Purchaser, Owner Trustee and Indenture Trustee at
least 60 days' prior written notice of any relocation of its principal executive
office if, as a result of such relocation, the applicable provisions of the UCC
would require the filing of any amendment of any previously filed financing or
continuation statement or of any new financing statement and shall promptly file
any such amendment or new financing statement.

      (d) Seller shall maintain its computer systems relating to installment
loan recordkeeping so that, from and after the time of sale under this Agreement
of its Receivables, Seller's master computer records (including any backup
archives) that refer to a Receivable shall indicate clearly the interest of
Purchaser, Issuer and Indenture Trustee in such Receivable and that such
Receivable has been sold to Purchaser and by Purchaser to Issuer and is owned by
Issuer and has been pledged to Indenture Trustee pursuant to the Indenture.
Indication of Purchaser's, Issuer's and Indenture Trustee's interest in a
Receivable shall be deleted from or modified on Seller's computer systems when,
and only when, the related Receivable shall have been paid in full or
repurchased by Seller or purchased by Servicer.

      (e) If at any time Seller shall propose to sell, grant a security interest
in or otherwise transfer any interest in automotive receivables to any
prospective purchaser, lender or other transferee, Seller shall give to such
prospective purchaser, lender or other transferee computer tapes, records or
printouts (including any restored from backup archives) that, if they shall
refer in any manner whatsoever to any Receivable, shall indicate clearly that
such Receivable has been sold to Purchaser and then sold by Purchaser to Issuer
and pledged to Indenture Trustee.

      (f) Seller shall permit Purchaser, Owner Trustee and Indenture Trustee and
its agents at any time during normal business hours to inspect, audit and make
copies of and abstracts from Seller's records regarding any Receivable.

      (g) Upon request at any time Purchaser, Owner Trustee or Indenture Trustee
