to the Owner Trustee pursuant to the Sale and Servicing Agreement, all payments
of principal and interest on or in respect of the Receivables received after the
Cutoff Date.

          SECTION 2.3   Transfer of Receivables. Pursuant to the Sale and
Servicing Agreement, the Purchaser will assign all of its right, title and
interest in, to and under the Receivables and other assets described in Section

     originated by the Seller or an Affiliate of the Seller in the ordinary
     course of business in connection with the sale of a new or used motor
     vehicle and has been fully and properly executed by the parties thereto,
     (ii) 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, (iii) provides for level
     monthly payments that fully amortize the Amount Financed by maturity
     (except that the period between the date of such Receivable and the date of
     the first Scheduled Payment may be less than or greater than one month and
     the amount of the first and last Scheduled Payments may be less than or
     greater than the level payments) and yield interest at the related APR,
     (iv) provides for, in the event that such Receivable is prepaid, a
     prepayment that fully pays the Principal Balance of such Receivable with
     interest at the related APR through the date of payment, (v) is a retail
     installment sale contract substantially in the form of Exhibit B, (vi) is
     secured by a new or used motor vehicle that had not been repossessed as of
     the Cutoff Date, (vii) is a Simple Interest Receivable, (viii) relates to
     an Obligor who has made at least one payment under such Receivable as of
     the Cutoff Date and (ix) relates to an Obligor whose mailing address is
     located in any State.

              (ii)  Receivable Schedule. The information set forth in the
     Receivable Schedule was true and correct in all material respects as of the
     opening of business on the Cutoff Date, and no selection procedures
     believed to be adverse to the Depositor and/or the Noteholders were
     utilized in selecting the Receivables from those retail installment sale
     contracts which met the criteria contained in this Agreement. The
     information set forth in the compact disk or other listing regarding the
     Receivables made available to the Depositor and its assigns (which compact
     disk or other listing is required to be delivered as specified herein) is
     true and correct in all material respects.

             (iii)  Compliance with Law. Each Receivable and the sale of the
     related Financed Vehicle complied, at the time such Receivable was
     originated and complies, as of the Closing Date, 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 Federal Reserve Board's Regulations B and
     Z, the Soldiers' and Sailors' Civil Relief Act of 1940, state adaptations
     of the National Consumer Act and the Uniform Consumer Credit Code and any
     other consumer credit, equal opportunity and disclosure laws applicable to
     such Receivable and sale.

              (iv)  Binding Obligation. Each Receivable represents the genuine,
     legal, valid and binding payment obligation in writing of the related
     Obligor, enforceable by the holder thereof in all material respects in
     accordance with its terms, except as enforceability may be limited by
     bankruptcy, insolvency, reorganization, liquidation or

                                       8

<PAGE>

     other similar laws affecting the enforcement of creditors' rights generally
     and by general principles of equity.

               (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. The Servicer has received, or will receive within 180 days
     after the Closing Date, the original certificate of title for each Financed
     Vehicle (other than any Financed Vehicle that is subject to a certificate
     of title statute or motor vehicle registration law that does not require
     that the original certificate of title for such Financed Vehicle be
     delivered to the Seller).

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

            (viii)  No Waiver. No provision of any Receivable has been waived
     in such a manner that such Receivable fails to meet all of the
     representations and warranties made by the Seller in this Section 3.2(b)
     with respect thereto.

              (ix)  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 to any right of rescission,
     setoff, counterclaim or defense, including the defense of usury, and the
     Seller has no knowledge of any such right of rescission, setoff,
     counterclaim or defense being asserted or threatened with respect to any
     Receivable.

               (x)  No Liens. The Seller has no knowledge of any liens or claims
     that have been filed, including liens for work, labor or materials or for
     unpaid state or federal taxes, relating to any Financed Vehicle that are
     prior to, or equal or coordinate with, the security interest in such
     Financed Vehicle created by the related Receivable.

              (xi)  No Default. 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

                                       9

<PAGE>

     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.

            (xiii)  Security Interest Matters. This Agreement creates a valid
     and continuing "security interest" (as defined in the Relevant UCC) in the
     Receivables in favor of the Depositor, which security interest is prior to
     all other Liens and is enforceable as such as against creditors of and
     purchasers from the Seller. With respect to each Receivable, the Seller has
     taken all steps necessary to perfect its security interest against the
     related Obligor in the related Financed Vehicle. The Receivables constitute
     "tangible chattel paper" (as defined in the Relevant UCC). The Seller has
     caused or will cause prior to the Closing Date the filing of all
     appropriate financing statements in the proper filing offices in the
     appropriate jurisdictions under applicable law necessary to perfect the
     security interest in the Receivables granted to the Depositor under this
     Agreement. Other than the security interest granted to the Depositor under
     this Agreement, 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 Depositor under the Sale and Servicing
     Agreement or that has been terminated. 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 Trust 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 Trust (as assignee of the
     Depositor) 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 Trust." All financing
     statements filed or to be filed against the Seller in favor of the
     Indenture Trustee (as assignee of the Trust) 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. The Seller has not entered into any
     agreement with any account debtor that prohibits, restricts or conditions
     the assignment of the Receivables.

                                       10

     each Receivable.

     Principal Balance of not more than $60,000 and a remaining Principal
     Balance as of the Cutoff Date of not less than $500.

           (xviii)  No Bankrupt Obligors. As of the Cutoff Date, no
     Receivable was due from an Obligor that was the subject of a proceeding
     under the Bankruptcy Code of the United States or was bankrupt.

             (xix)  New and Used Vehicles. As of the Cutoff Date, approximately
     4.11% of the Pool Balance related to Receivables secured by new Financed
     Vehicles and approximately 95.89% of the Pool Balance related to
     Receivables secured by used Financed Vehicles.

              (xx)  Origination. Each Receivable was originated after April 17,
     1998.

             (xxi)  Term to Maturity. Each Receivable had an original term to
     maturity of not more than 72 months and not less than 12 months and a
     remaining term to maturity as of the Cutoff Date of not more than 71 months
     and not less than three months.

            (xxii)  Weighted Average Remaining Term to Maturity. As of the
     Cutoff Date, the weighted average remaining term to maturity of the
     Receivables was approximately 57 months.

           (xxiii)  Annual Percentage Rate. Each Receivable has an APR of at
     least 4.95% and not more than 25.00%.

            (xxiv)  Location of Receivable Files. The Receivable Files are
     maintained at the location listed in Schedule 2 to the Sale and Servicing
     Agreement.

             (xxv)  Simple Interest Method. All payments with respect to the
     Receivables have been allocated consistently in accordance with the Simple
     Interest Method.

            (xxvi)  No Delinquent Receivables. As of the Cutoff Date, no
     payment due under any Receivable was more than 30 days past due.

           (xxvii)  Insurance. Each Obligor has obtained or agreed to obtain
     physical damage insurance (which insurance shall not be force placed
     insurance) covering the related Financed Vehicle in accordance with the
     Seller's normal requirements.

          (xxviii)  Fair Market Value. The Receivables Purchase Price
     represents the fair market value of the Receivables.

            (xxix)  Custodial Agreements. Immediately prior to the transfer of
     the Receivables by the Seller to the Depositor, the Seller or an Affiliate
     of the Seller had possession of the Receivable Files and there were no, and
     there will not be any, custodial

                                       11

<PAGE>

     agreements in effect materially adversely affecting the right or ability of
     the Seller to make, or cause to be made, any delivery required under this
     Agreement.

             (xxx)  Bulk Transfer Laws. The transfer of the Receivables and the
     Receivable Files by the Seller to the Depositor pursuant to this Agreement
     is not subject to the bulk transfer laws or any similar statutory
     provisions in effect in any applicable jurisdiction.

          (c)  The Seller shall indemnify the Purchaser and hold the Purchaser
harmless against any losses, penalties, fines, forfeitures, legal fees and
related costs, judgments and other costs and expenses resulting from any third
party claim, demand, defense or assertion based on or grounded upon, or
resulting from, a breach of the Seller's representations and warranties set
forth in Section 3.2(b). The Trustees shall also have the remedies provided in
the Sale and Servicing Agreement.

          (d)  Any cause of action against the Seller relating to or arising out
of the breach of any of its representations and warranties set forth in Section
3.2(b) shall accrue as to any Receivable upon (i) discovery of such breach by
the Purchaser or either Trustee or notice thereof by the Seller to the
Purchaser, (ii) failure by the Seller to cure such breach and (iii) demand upon
the Seller by the Purchaser for all amounts payable in respect of such
Receivable under this Agreement.

          (e)  The Purchaser or the Seller, as the case may be, shall inform the
other parties promptly, in writing, upon discovery of any breach of the Seller's
representations and warranties set forth in Section 3.2(b) which materially and
adversely affects the interests of the Noteholders in any Receivable.

          (f)  If a breach of any representation or warranty set forth in
Section 3.2(b) which materially and adversely affects the interests of the
Purchaser, the Trust or the Noteholders in any Receivable shall not have been
cured by the close of business on the last day of the Collection Period which
includes the thirtieth day after the date on which the Seller becomes aware of,
or receives written notice from the Servicer, the Purchaser or the Owner Trustee

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 and all other related assets

property conveyed by the Seller to the Purchaser hereunder to be promptly
authorized, recorded, registered and filed, and at all times to be kept

the Purchaser hereunder to the Receivables and such other property. The Seller

statement or of any new financing statement and, within 30 days after such
relocation, shall authorize and file such financing statements or amendments as
may be necessary to continue the perfection of the interest of the Purchaser in
the Receivables and the proceeds thereof. The Seller shall at all times maintain

executive office and the location of the office where the Receivables Files and
any accounts and records relating to the Receivables are kept within the United
States.

          (f)  If at any time the Seller shall propose to sell, grant a security
interest in or otherwise transfer any interest in any motor vehicle retail
installment sale contract to any prospective purchaser, lender or other
transferee, the Seller shall give to such prospective purchaser, lender or other
transferee computer tapes, compact disks, records or print-outs (including any
restored from back-up archives) that, if they shall refer in any manner
whatsoever to any Receivable, shall indicate clearly and unambiguously that such

request, furnish to the Purchaser, within ten days, a list of all Receivables
(by receivable number and name of Obligor) then owned by the Purchaser, together

hereunder, the Seller covenants that it will not sell, pledge, assign or
transfer to any other Person, or grant, create, incur, assume or suffer to exist
any Lien on any Receivable, whether now existing or hereafter created, or any
interest therein; the Seller will immediately notify the Purchaser of the
existence of any Lien on any Receivable and, in the event that the interests of
the Noteholders in such Receivable are materially and adversely affected, such
Receivable shall be repurchased from the Purchaser by the Seller in the manner
and with the effect specified in Section 3.2(f), and the Seller shall defend the
right, title and interest of the Purchaser in, to and under the Receivables,
whether now existing or hereafter created, against all claims of third parties
claiming through or under the Seller.

to deliver in kind upon receipt to the Servicer under the Sale and Servicing

no action, nor omit to take any action, which would impair the rights of the

payments due on any Receivable.

          SECTION 5.5   Costs and Expenses. The Seller shall pay all reasonable
costs and expenses incurred in connection with the perfection of the Purchaser's
right, title and interest in, to and under the Receivables.

indemnify and hold the Purchaser and the Issuer and their respective assigns and
their attorneys, accountants, employees, officers and directors harmless from
and against all losses, costs, liabilities, claims, damages and expenses of
every kind and character, as incurred, resulting from or relating to or arising
out of (i) the inaccuracy, nonfulfillment or breach of any representation,
warranty, covenant or agreement made by the Seller in this Agreement, (ii) any
legal action, including any counterclaim, that has either been settled by the
litigants (which settlement, if the Seller is not a party thereto shall be with
the consent of the Seller) or has proceeded to judgment by a court of competent
jurisdiction, in either case to the extent it is based upon alleged facts that,
if true, would constitute a breach of any representation, warranty, covenant or
agreement made by the Seller in this Agreement, (iii) any actions or omissions
of the Seller or any employee or agent of the Seller occurring prior to the
Closing Date with respect to any Receivable or Financed Vehicle or (iv) any
failure of a Receivable to be originated in compliance with all requirements of
law. These indemnity obligations shall be in addition to any obligation that the
Seller may otherwise have.
