     time) a default under, the certificate of incorporation or bylaws of
     Purchaser, or conflict with or breach any of the terms or provisions of, or
     constitute (with or without notice or lapse of time) a default under, any
     indenture, agreement, mortgage, deed of trust or other instrument to which
     Purchaser is a party or by which Purchaser is bound or to which any of its
     properties are subject, or result in the creation or imposition of any Lien
     upon any of its properties pursuant to the terms of any such indenture,
     agreement, mortgage, deed of trust or other instrument (other than the Sale
     and Servicing Agreement and the Spread Account Agreement), or violate any
     law, order, rule or regulation, applicable to Purchaser or its properties,
     of any federal or state regulatory body, any court, administrative agency,
     or other governmental instrumentality having jurisdiction over Purchaser or
     any of its properties.

          (g) No Proceedings. There are no proceedings or investigations
     pending, or, to the knowledge of Purchaser, threatened against Purchaser,
     before any court, regulatory body, administrative agency, or other tribunal
     or governmental instrumentality having jurisdiction over Purchaser or its
     properties: (i) asserting the invalidity of this Agreement or any of the
     Related Documents, (ii) seeking to prevent the consummation of any of the
     transactions contemplated by this Agreement or any of the Related
     Documents, (iii) seeking any determination or ruling that might materially
     and adversely affect the performance by Purchaser of its obligations under,
     or the validity or enforceability of, this Agreement or any of the Related
     Documents or (iv) that may adversely affect the federal or state income tax
     attributes of, or seeking to impose any excise, franchise, transfer or
     similar tax upon, the transfer and acquisition of the Receivables and the
     Other Conveyed Property hereunder or the transfer of the Receivables and
     the Other Conveyed Property to the Issuer pursuant to the Sale and
     Servicing Agreement.

          In the event of any breach of a representation and warranty made by
Purchaser hereunder, Seller covenants and agrees that it will not take any
action to pursue any remedy that it may have hereunder, in law, in equity or
otherwise, until a year and a day have passed since the date on which all Notes,
Certificates, pass-through certificates or other similar securities issued by
Purchaser, or a trust or similar vehicle formed by Purchaser, have been paid in
full. Seller and Purchaser agree that damages will not be an adequate remedy for
such breach and that this covenant may be specifically enforced by Purchaser,
Issuer or by the Trustee on behalf of the Noteholders and Owner Trustee on
behalf of the Certificateholder.

                                  ARTICLE IV.

                               COVENANTS OF SELLER

          SECTION 4.1   Protection of Title of Purchaser.

          (a) At or prior to the Closing Date, Seller shall have filed or caused
     to be filed a UCC-1 financing statement, naming Seller as seller or debtor,
     naming Purchaser as purchaser or secured party and describing the Initial
     Receivables and the Initial Other Conveyed Property being sold by it to
     Purchaser as collateral, with the office of the Secretary of State of the
     State of Delaware and in such other locations as Purchaser shall

                                       8

<PAGE>

     have required. At or prior to any Subsequent Transfer Date, Seller shall
     file or cause to be filed a UCC-1 financing statement naming Seller as
     seller or debtor, naming the Purchaser as purchaser or secured party and
     describing the Subsequent Receivables and the Subsequent Other Conveyed
     Property being sold by it to the Purchaser as collateral, with the office
     of the Secretary of State of the State of Delaware and in such other
     locations as Purchaser shall require. From time to time thereafter, Seller
     shall execute and file such financing statements and cause to be executed
     and filed such continuation statements, all in such manner and in such
     places as may be required by law fully to preserve, maintain and protect
     the interest of Purchaser under this Agreement, of the Issuer under the
     Sale and Servicing Agreement and of the Trust Collateral Agent under the
     Indenture in the Receivables and the Other Conveyed Property and in the
     proceeds thereof. Seller shall deliver (or cause to be delivered) to
     Purchaser, the Trust Collateral Agent and the Insurer file-stamped copies
     of, or filing receipts for, any document filed as provided above, as soon
     as available following such filing. In the event that Seller fails to
     perform its obligations under this subsection, Purchaser, Issuer or the
     Trust Collateral Agent may do so, at the expense of such Seller. In
     furtherance of the foregoing, the Seller hereby authorizes the Purchaser,
     the Issuer or the Trust Collateral Agent to file a record or records (as
     defined in the applicable UCC), including, without limitation, financing
     statements, in all jurisdictions and with all filing offices as each may
     determine, in its sole discretion, are necessary or advisable to perfect
     the security interest granted to the Purchaser pursuant to Section 6.9 of
     this Agreement. Such financing statements may describe the collateral in
     the same manner as described herein or may contain an indication or
     description of collateral that describes such property in any other manner
     as such party may determine, in its sole discretion, is necessary,
     advisable or prudent to ensure the perfection of the security interest in
     the collateral granted to the Purchaser herein.

          (b) Seller shall not change its name, identity, state of incorporation
     or corporate structure in any manner that would, could or might make any
     financing statement or continuation statement filed by Seller (or by
     Purchaser, Issuer or the Trust Collateral Agent on behalf of Seller) in
     accordance with paragraph (a) above seriously misleading within the meaning
     of ss.9-506 of the applicable UCC, unless they shall have given Purchaser,
     Issuer and the Trust Collateral Agent at least 60 days' prior written
     notice thereof, and shall promptly file appropriate amendments to all
     previously filed financing statements and continuation statements.

          (c) Seller shall give Purchaser, the Issuer, the Insurer (so long as
     an Insurer Default shall not have occurred and be continuing) and the Trust
     Collateral Agent at least 60 days' prior written notice of any relocation
     that would result in a change of location of the debtor within the meaning
     of Section 9-307 of the applicable UCC. Seller shall at all times maintain
     each office from which it services Receivables and its principal executive
     office within the United States of America.

          (d) Prior to the Closing Date and with respect to Subsequent
     Receivables, the Subsequent Transfer Date, Seller has maintained accounts
     and records as to each Receivable accurately and in sufficient detail to
     permit (i) the reader thereof to know at any time as of or prior to the
     Closing Date and with respect to Subsequent Receivables,

                                       9

<PAGE>

     the Subsequent Transfer Date, the status of such Receivable, including
     payments and recoveries made and payments owing (and the nature of each)
     and (ii) reconciliation between payments or recoveries on (or with respect
     to) each Receivable and the Principal Balance as of the Closing Date and
     with respect to Subsequent Receivables, the Subsequent Transfer Date.
     Seller shall maintain its computer systems so that, from and after the time
     of sale under this Agreement of the Receivables to Purchaser, and the
     conveyance of the Receivables by Purchaser to the Issuer, Seller's master
     computer records (including archives) that shall refer to a Receivable
     indicate clearly that such Receivable has been sold to Purchaser and has
     been conveyed by Purchaser to the Issuer. Indication of the Issuer's
     ownership of a Receivable shall be deleted from or modified on Seller's
     computer systems when, and only when, the Receivable shall become a
     Purchased Receivable or shall have been paid in full.

          (e) If at any time Seller shall propose to sell, grant a security
     interest in, or otherwise transfer any interest in any motor vehicle
     receivables to any prospective purchaser, lender or other transferee,
     Seller shall give to such prospective purchaser, lender, or other
     transferee computer tapes, records, or print-outs (including any restored
     from archives) that, if they shall refer in any manner whatsoever to any
     Receivable (other than a Purchased Receivable), shall indicate clearly that
     such Receivable has been sold to Purchaser, sold by Purchaser to Issuer,
     and is owned by the Issuer.

          SECTION 4.2   Other Liens or Interests. Except for the conveyances
hereunder, Seller will not sell, pledge, assign or transfer to any other Person,
or grant, create, incur, assume or suffer to exist any Lien on the Receivables
or the Other Conveyed Property or any interest therein, and Seller shall defend
the right, title, and interest of Purchaser and the Issuer in and to the
Receivables and the Other Conveyed Property against all claims of third parties
claiming through or under Seller.

          SECTION 4.3   Costs and Expenses. Seller shall pay all reasonable
costs and disbursements in connection with the performance of its obligations
hereunder and under its Related Documents.

          SECTION 4.4   Indemnification.

          (a) Seller shall defend, indemnify and hold harmless Purchaser, the
     Issuer, the Trust Collateral Agent, the Trustee, the Backup Servicer, the
     Owner Trustee, the Noteholders and the Certificateholder from and against
     any and all costs, expenses, losses, damages, claims, and liabilities,
     arising out of or resulting from any breach of any of Seller's
     representations and warranties contained herein.

          (b) Seller shall defend, indemnify and hold harmless Purchaser, the
     Issuer, the Trust Collateral Agent, the Trustee, the Backup Servicer, the
     Owner Trustee, the Noteholders and the Certificateholder from and against
     any and all costs, expenses, losses, damages, claims, and liabilities,
     arising out of or resulting from the use, ownership or operation by Seller
     or any affiliate thereof of a Financed Vehicle.

                                       10

          (c) Seller shall defend, indemnify and hold harmless Purchaser, the
     Issuer, the Trust Collateral Agent, the Trustee, the Backup Servicer, the
     Owner Trustee, the Noteholders and the Certificateholder from and against
     any and all costs, expenses, losses, damages, claims and liabilities
     arising out of or resulting from any action taken, or failed to be taken,
     by it in respect of any portion of the Receivables other than in accordance
     with this Agreement or the Sale and Servicing Agreement.

          (d) Seller agrees to pay, and shall defend, indemnify and hold
     harmless Purchaser, the Issuer, the Trust Collateral Agent, the Trustee,
     the Backup Servicer, the Owner Trustee, the Noteholders and the
     Certificateholder from and against any taxes that may at any time be
     asserted against Purchaser, the Issuer, the Trust Collateral Agent, the
     Trustee, the Backup Servicer, the Owner Trustee, the Noteholders and the
     Certificateholder with respect to the transactions contemplated in this
     Agreement, including, without limitation, any sales, gross receipts,
     general corporation, tangible or intangible personal property, privilege,
     or license taxes (but not including any taxes asserted with respect to, and
     as of the date of, the sale, transfer and assignment of the Receivables and
     the Other Conveyed Property to Purchaser and by Purchaser to the Issuer or
     the issuance and original sale of the Notes or issuance of the Certificate,
     or asserted with respect to ownership of the Receivables and Other Conveyed
     Property which shall be indemnified by Seller pursuant to clause (e) below,
     or federal, state or other income taxes, arising out of distributions on
     the Notes or the Certificate or transfer taxes arising in connection with
     the transfer of the Notes or the Certificate) and costs and expenses in
     defending against the same, arising by reason of the acts to be performed
     by Seller under this Agreement or imposed against such Persons.

          (e) Seller agrees to pay, and to indemnify, defend and hold harmless
     Purchaser, the Issuer, the Trust Collateral Agent, the Trustee, the Backup
     Servicer, the Owner Trustee, the Noteholders and the Certificateholder
     from, any taxes which may at any time be asserted against such Persons with
     respect to, and as of the date of, the conveyance or ownership of the
     Receivables or the Other Conveyed Property hereunder and under any
     Subsequent Purchase Agreement and the conveyance or ownership of the
     Receivables under the Sale and Servicing Agreement or the issuance and
     original sale of the Notes or the issuance of the Certificate, including,
     without limitation, any sales, gross receipts, personal property, tangible
     or intangible personal property, privilege or license taxes (but not
     including any federal or other income taxes, including franchise taxes,
     arising out of the transactions contemplated hereby or transfer taxes
     arising in connection with the transfer of the Notes or the Certificate)
     and costs and expenses in defending against the same, arising by reason of
     the acts to be performed by Seller under this Agreement or imposed against
     such Persons.

          (f) Seller shall defend, indemnify, and hold harmless Purchaser, the
     Issuer, the Trust Collateral Agent, the Trustee, the Backup Servicer, the
     Owner Trustee, the Noteholders and the Certificateholder from and against
     any and all costs, expenses, losses, claims, damages, and liabilities to
     the extent that such cost, expense, loss, claim, damage, or liability arose
     out of, or was imposed upon Purchaser, the Issuer, the Trust Collateral
     Agent, the Trustee, the Backup Servicer, the Owner Trustee, the Noteholders
     or the Certificateholder through the negligence, willful misfeasance, or
     bad faith of Seller

                                       11

<PAGE>

     in the performance of its duties under this Agreement or by reason of
     reckless disregard of Seller's obligations and duties under this Agreement.

          (g) Seller shall indemnify, defend and hold harmless Purchaser, the
     Issuer, the Trust Collateral Agent, the Trustee, the Backup Servicer, the
     Owner Trustee, the Noteholders and the Certificateholder from and against
     any loss, liability or expense incurred by reason of the violation by
     Seller of federal or state securities laws in connection with the
     registration or the sale of the Notes.

          (h) Seller shall indemnify, defend and hold harmless Purchaser, the
     Issuer, the Trust Collateral Agent, the Trustee, the Backup Servicer, the
     Owner Trustee, the Noteholders and the Certificateholder from and against
     any loss, liability or expense imposed upon, or incurred by, Purchaser, the
     Issuer, the Trust Collateral Agent, the Trustee, the Backup Servicer, the
     Owner Trustee, the Noteholders or the Certificateholder as result of the
     failure of any Receivable, or the sale of the related Financed Vehicle, to
     comply with all requirements of applicable law.

          (i) Seller shall defend, indemnify, and hold harmless Purchaser from
     and against all costs, expenses, losses, claims, damages, and liabilities
     arising out of or incurred in connection with the acceptance or performance
     of Seller's trusts and duties as Servicer under the Sale and Servicing
     Agreement, except to the extent that such cost, expense, loss, claim,
     damage, or liability shall be due to the willful misfeasance, bad faith, or
     negligence (except for errors in judgment) of Purchaser.

          (j) Seller shall indemnify the Owner Trustee and its officers,
     directors, successors, assigns, agents and servants jointly and severally
     with the Purchaser pursuant to Section 7.2 of the Trust Agreement.

          Indemnification under this Section 4.4 shall include reasonable fees
and expenses of counsel and expenses of litigation and shall survive payment of
the Notes and the Certificate. The indemnity obligations hereunder shall be in
addition to any obligation that Seller may otherwise have.

                                   ARTICLE V.

                                   REPURCHASES

          SECTION 5.1   Repurchase of Receivables Upon Breach of Warranty. Upon
the occurrence of a Repurchase Event, Seller shall, unless the breach which is
the subject of such Repurchase Event shall have been cured in all material
respects, repurchase the Receivable relating thereto from the Issuer and,
simultaneously with the repurchase of the Receivable, Seller shall deposit the
Purchase Amount in full, without deduction or offset, to the Collection Account,
pursuant to Section 3.2 of the Sale and Servicing Agreement. It is understood
and agreed that, except as set forth in Section 6.1 hereof, the obligation of
Seller to repurchase any Receivable, as to which a breach occurred and is
continuing, shall, if such obligation is fulfilled, constitute the sole remedy
against Seller for such breach available to Purchaser, the Issuer, the Insurer,
the Backup Servicer, the Noteholders, the Certificateholder, the Trust
Collateral Agent on behalf of

                                       12

<PAGE>

the Noteholders or the Owner Trustee on behalf of the Certificateholder. The
provisions of this Section 5.1 are intended to grant the Issuer and the Trust
Collateral Agent a direct right against Seller to demand performance hereunder,
and in connection therewith, Seller waives any requirement of prior demand
against Purchaser with respect to such repurchase obligation. Any such
repurchase shall take place in the manner specified in Section 3.2 of the Sale
and Servicing Agreement. Notwithstanding any other provision of this Agreement
or the Sale and Servicing Agreement to the contrary, the obligation of Seller
under this Section shall not terminate upon a termination of Seller as Servicer
under the Sale and Servicing Agreement and shall be performed in accordance with
the terms hereof notwithstanding the failure of the Servicer or Purchaser to
perform any of their respective obligations with respect to such Receivable
under the Sale and Servicing Agreement.

          In addition to the foregoing and notwithstanding whether the related
Receivable shall have been purchased by Seller, Seller shall indemnify the
Issuer, the Trust Collateral Agent, the Trustee, the Backup Servicer, the Owner
Trustee, the Insurer, the Noteholders and the Certificateholder from and against
all costs, expenses, losses, damages, claims and liabilities, including
reasonable fees and expenses of counsel, which may be asserted against or
incurred by any of them as a result of third party claims arising out of the
events or facts giving rise to such Repurchase Events.

          SECTION 5.2   Reassignment of Purchased Receivables. Upon deposit in
the Collection Account of the Purchase Amount of any Receivable repurchased by
Seller under Section 5.1 hereof, Purchaser and the Issuer shall take such steps
as may be reasonably requested by Seller in order to assign to Seller all of
Purchaser's and the Issuer's right, title and interest in and to such Receivable
and all security and documents and all Other Conveyed Property conveyed to
Purchaser and the Issuer directly relating thereto, without recourse,
representation or warranty, except as to the absence of Liens created by or
arising as a result of actions of Purchaser or the Issuer. Such assignment shall
be a sale and assignment outright, and not for security. If, following the
reassignment of a Purchased Receivable, in any enforcement suit or legal
proceeding, it is held that Seller may not enforce any such Receivable on the
ground that it shall not be a real party in interest or a holder entitled to
enforce the Receivable, Purchaser and the Issuer shall, at the expense of
Seller, take such steps as Seller deems reasonably necessary to enforce the
Receivable, including bringing suit in Purchaser's or in the Issuer's name.

          SECTION 5.3   Waivers. No failure or delay on the part of Purchaser,
or the Issuer as assignee of Purchaser, in exercising any power, right or remedy
under this Agreement shall operate as a waiver thereof, nor shall any single or
partial exercise of any such power, right or remedy preclude any other or future
exercise thereof or the exercise of any other power, right or remedy.

                                  ARTICLE VI.
                                  MISCELLANEOUS

          SECTION 6.1   Liability of Seller. Seller shall be liable in
accordance herewith only to the extent of the obligations in this Agreement
specifically undertaken by Seller and the representations and warranties of
Seller.

                                       13

<PAGE>

          SECTION 6.2   Merger or Consolidation of Seller or Purchaser. Any
corporation or other entity (i) into which Seller or Purchaser may be merged or
consolidated, (ii) resulting from any merger or consolidation to which Seller or
Purchaser is a party or (iii) succeeding to the business of Seller or Purchaser,
in the case of Purchaser, which corporation has a certificate of incorporation
containing provisions relating to limitations on business and other matters
substantively identical to those contained in Purchaser's certificate of
incorporation, provided that in any of the foregoing cases such corporation
shall execute an agreement of assumption to perform every obligation of Seller
or Purchaser, as the case may be, under this Agreement and, whether or not such
assumption agreement is executed, shall be the successor to Seller or Purchaser,
as the case may be, hereunder (without relieving Seller or Purchaser of their
responsibilities hereunder, if it survives such merger or consolidation) without
the execution or filing of any document or any further action by any of the
parties to this Agreement. Notwithstanding the foregoing, so long as an Insurer
Default shall not have occurred and be continuing, Purchaser shall not merge or
consolidate with any other Person or permit any other Person to become the
successor to Purchaser's business without the prior written consent of the
Insurer. Seller or Purchaser shall promptly inform the other party, the Issuer,
the Trust Collateral Agent, the Owner Trustee and, so long as an Insurer Default
shall not have occurred and be continuing, the Insurer of such merger,
consolidation or purchase and assumption. Notwithstanding the foregoing, as a
condition to the consummation of the transactions referred to in clauses (i),
(ii) and (iii) above, (x) immediately after giving effect to such transaction,
no representation or warranty made pursuant to Sections 3.1 and 3.2 of this
Agreement shall have been breached (for purposes hereof, such representations
and warranties shall speak as of the date of the consummation of such
transaction) and no event that, after notice or lapse of time, or both, would
become an event of default under the Insurance Agreement, shall have occurred
and be continuing, (y) Seller or Purchaser, as applicable, shall have delivered
written notice of such consolidation, merger or purchase and assumption to the
Rating Agencies prior to the consummation of such transaction and shall have
delivered to the Issuer and the Trust Collateral Agent an Officer's Certificate
and an Opinion of Counsel each stating that such consolidation, merger or
succession and such agreement of assumption comply with this Section 6.2 and
that all conditions precedent, if any, provided for in this Agreement relating
to such transaction have been complied with, and (z) Seller or Purchaser, as
applicable, shall have delivered to the Issuer and the Trust Collateral Agent an
Opinion of Counsel, stating, in the opinion of such counsel, either (A) all
financing statements and continuation statements and amendments thereto have
been executed and filed that are necessary to preserve and protect the interest
of the Issuer and the Trust Collateral Agent in the Receivables and reciting the
details of the filings or (B) no such action shall be necessary to preserve and
protect such interest.

          SECTION 6.3   Limitation on Liability of Seller and Others. Seller and
any director, officer, employee or agent thereof may rely in good faith on the
advice of counsel or on any document of any kind prima facie properly executed
and submitted by any Person respecting any matters arising under this Agreement.
Seller shall not be under any obligation to appear in, prosecute or defend any
legal action that is not incidental to its obligations under this Agreement or
its Related Documents and that in its opinion may involve it in any expense or
liability.

          SECTION 6.4   Seller May Own Notes or the Certificate. Subject to the
provisions of the Sale and Servicing Agreement, Seller and any Affiliate of
Seller may in their

                                       14

<PAGE>

individual or any other capacity become the owner or pledgee of Notes or the
Certificate with the same rights as they would have if they were not Seller or
an Affiliate thereof.

          SECTION 6.5  Amendment.

          (a) This Agreement may be amended by Seller and Purchaser with the
     prior written consent of the Insurer (so long as an Insurer Default shall
     not have occurred and be continuing) but without the consent of the Trust
     Collateral Agent, the Owner Trustee, the Certificateholder or any of the
     Noteholders (i) to cure any ambiguity or (ii) to correct any provisions in
     this Agreement; provided, however, that such action shall not, as evidenced
     by an Opinion of Counsel delivered to the Issuer, the Owner Trustee and the
     Trust Collateral Agent, adversely affect in any material respect the
     interests of any Certificateholder or Noteholder.

          (b) This Agreement may also be amended from time to time by Seller and
     Purchaser, with the prior written consent of the Insurer (so long as an
     Insurer Default shall not have occurred and be continuing) and with the
     consent of the Trust Collateral Agent and, if required, the
     Certificateholder and the Noteholders, in accordance with the Sale and
     Servicing Agreement, for the purpose of adding any provisions to or
     changing in any manner or eliminating any of the provisions of this
     Agreement, or of modifying in any manner the rights of the
     Certificateholder or Noteholders; provided, however, the Seller provides
     the Trust Collateral Agent with an Opinion of Counsel, (which may be
     provided by the Seller's internal counsel) that no such amendment shall
     increase or reduce in any manner the amount of, or accelerate or delay the
     timing of, collections of payments on Receivables or distributions that
     shall be required to be made on any Note or Certificate.

          (c) Prior to the execution of any such amendment or consent, Seller
     shall have furnished written notification of the substance of such
     amendment or consent to each Rating Agency.

          (d) It shall not be necessary for the consent of Certificateholder or
     Noteholders pursuant to this Section to approve the particular form of any
     proposed amendment or consent, but it shall be sufficient if such consent
     shall approve the substance thereof. The manner of obtaining such consents
     and of evidencing the authorization of the execution thereof by
     Certificateholder or Noteholders shall be subject to such reasonable
     requirements as the Trust Collateral Agent may prescribe, including the
     establishment of record dates. The consent of a Holder of a Certificate or
     a Note given pursuant to this Section or pursuant to any other provision of
     this Agreement shall be conclusive and binding on such Holder and on all
     future Holders of such Certificate or Note and of any Certificate or Note
     issued upon the transfer thereof or in exchange thereof or in lieu thereof
     whether or not notation of such consent is made upon the Certificate or
     Note.

          SECTION 6.6   Notices. All demands, notices and communications to
Seller or Purchaser hereunder shall be in writing, personally delivered, or sent
by telecopier (subsequently confirmed in writing), reputable overnight courier
or mailed by certified mail, return receipt

                                       15

               SECTION 6.10 Governing Law. This Agreement shall be construed in
accordance with the laws of the State of New York without regard to the
principles of conflicts of laws thereof and the obligations, rights and remedies
of the parties under this Agreement shall be determined in accordance with such
laws.

               SECTION 6.11 Counterparts. For the purpose of facilitating the
execution of this Agreement and for other purposes, this Agreement may be
executed simultaneously in any number of counterparts, each of which
counterparts shall be deemed to be an original, and all of which counterparts
shall constitute but one and the same instrument.

               SECTION 6.12 Conveyance of the Receivables and the Other Conveyed
Property to the Issuer. Seller acknowledge that Purchaser intends, pursuant to
the Sale and Servicing Agreement, to convey the Receivables and the Other
Conveyed Property, together with its rights under this Agreement, to the Issuer
on the date hereof and on the Subsequent Transfer Date in the case of Subsequent
Receivables. Seller acknowledges and consents to such conveyance and pledge and

representations and warranties of Seller contained in this Agreement and the
rights of Purchaser hereunder are intended to benefit the Insurer, the Issuer,
the Owner Trustee, the Trust Collateral Agent, the Noteholders and the

to perform its duties and obligations hereunder, in accordance with the terms

Collateral Agent, the Noteholders and the Certificateholder and that,
notwithstanding anything to the contrary in this Agreement, Seller shall be

Agreement against Seller for the benefit of the Insurer, the Owner Trustee, the

                        REPRESENTATIONS AND WARRANTIES OF

              AMERICREDIT FINANCIAL SERVICES, INC. ("AMERICREDIT")

     1.  Characteristics of Receivables. Each Receivable (A) was originated (i)
by AmeriCredit, (ii) by a Dealer and purchased by AmeriCredit from such Dealer
under an existing Dealer Agreement or pursuant to a Dealer Assignment with
AmeriCredit and was validly assigned by such Dealer to AmeriCredit pursuant to a
Dealer Assignment or (iii) by a Third-Party Lender and purchased by AmeriCredit
from such Third-Party Lender under an existing Auto Loan Purchase and Sale
Agreement or pursuant to a Third-Party Lender Assignment with AmeriCredit and
was validly assigned by such Third-Party Lender to AmeriCredit pursuant to a
Third-Party Lender Assignment (B) was originated by AmeriCredit, such Dealer or
such Third-Party Lender for the retail sale of a Financed Vehicle in the
ordinary course of AmeriCredit's, the Dealer's or the Third-Party Lender's
business, in each case was originated in accordance with AmeriCredit's credit
policies and was fully and properly executed by the parties thereto, and
AmeriCredit, each Dealer and each Third-Party Lender had all necessary licenses
and permits to originate Receivables in the state where AmeriCredit, each such
Dealer or each such Third-Party Lender was located, (C) contains customary and
enforceable provisions such as to render the rights and remedies of the holder
thereof adequate for realization against the collateral security, (D) is a
Receivable which provides for level monthly payments (provided that the period
in the first Collection Period and the payment in the final Collection Period of
the Receivable may be minimally different from the normal period and level
payment) which, if made when due, shall fully amortize the Amount Financed over
the original term and (E) has not been amended or collections with respect to
which waived, other than as evidenced in the Receivable File relating thereto.

     2.  No Fraud or Misrepresentation. Each Receivable was originated (i) by
AmeriCredit, (ii) by a Dealer and was sold by the Dealer to AmeriCredit, or
(iii) by a Third-Party Lender and was sold by the Third-Party Lender to
AmeriCredit, and was sold by AmeriCredit to AFS Funding without any fraud or
misrepresentation on the part of such Dealer or Third-Party Lender in any case.

     3.  Compliance with Law. All requirements of applicable federal, state and
local laws, and regulations thereunder (including, without limitation, usury
laws, the Federal Truth-in-Lending Act, the Equal Credit Opportunity Act, the
Fair Credit Billing Act, the Fair Credit Reporting Act, the Fair Debt Collection
Practices Act, the Federal Trade Commission Act, the Moss-Magnuson Warranty Act,
the Federal Reserve Board's Regulations "B" and "Z" (including amendments to the
Federal Reserve's Official Staff Commentary to Regulation Z, effective October
1, 1998, concerning negative equity loans), the Soldiers' and Sailors' Civil
Relief Act of 1940, each applicable state Motor Vehicle Retail Installment Sales
Act, and state adaptations of the National Consumer Act and of the Uniform
Consumer Credit Code and other consumer credit laws and equal credit opportunity
and disclosure laws) in respect of the Receivables and the Financed Vehicles,
have been complied with in all material respects, and each Receivable and the
sale of the Financed Vehicle evidenced by each Receivable complied at the time
it was



<PAGE>

originated or made and now complies in all material respects with all applicable
legal requirements.

     4.   Origination. Each Receivable was originated in the United States.

     5.   Binding Obligation. Each Receivable represents the genuine, legal,
valid and binding payment obligation of the Obligor thereon, enforceable by the
holder thereof in accordance with its terms, except (A) as enforceability may be
limited by bankruptcy, insolvency, reorganization or similar laws affecting the
enforcement of creditors' rights generally and by equitable limitations on the
availability of specific remedies, regardless of whether such enforceability is
considered in a proceeding in equity or at law and (B) as such Receivable may be
modified by the application after the Cutoff Date of the Soldiers' and Sailors'
Civil Relief Act of 1940, as amended; and all parties to each Receivable had
full legal capacity to execute and deliver such Receivable and all other
documents related thereto and to grant the security interest purported to be
granted thereby.

     6.   No Government Obligor. No Obligor is the United States of America or
any State or any agency, department, subdivision or instrumentality thereof.

     7.   Obligor Bankruptcy. At the related Cutoff Date no Obligor had been
identified on the records of AmeriCredit as being the subject of a current
bankruptcy proceeding.

     8.   Schedules of Receivables. The information set forth in the Schedules
of Receivables has been produced from the Electronic Ledger and was true and
correct in all material respects as of the close of business on the related
Cutoff Date.

     9.   Marking Records. By the Closing Date or Subsequent Transfer Date, as
applicable, AmeriCredit will have caused the portions of the Electronic Ledger
relating to the Receivables to be clearly and unambiguously marked to show that
the Receivables have been sold to AFS Funding by AmeriCredit and resold by the
AFS Funding to the Trust in accordance with the terms of the Sale and Servicing
Agreement.

     10.  Computer Tape. The Computer Tape made available by AmeriCredit to AFS
Funding and to the Trust on the Closing Date or Subsequent Transfer Date, as
applicable, was complete and accurate as of the related Cutoff Date and includes
a description of the same Receivables that are described in the Schedule of
Receivables.

     11.  Adverse Selection. No selection procedures adverse to the Noteholders
or the Insurer were utilized in selecting the Receivables from those receivables
owned by AmeriCredit which met the selection criteria contained in the Sale and
Servicing Agreement.

     12.  Chattel Paper. The Receivables constitute chattel paper within the
meaning of the UCC as in effect in the States of Texas, New York and Delaware.

     13.  One Original. There is only one original executed copy of each
Receivable.

     14.  Receivable Files Complete. There exists a Receivable File pertaining
to each Receivable and such Receivable File contains (a) a fully executed
original of the Receivable, (b)

                                      B-2

<PAGE>

the original executed credit application, or a paper or electronic copy thereof
and (c) the original Lien Certificate or application therefor. Each of such
documents which is required to be signed by the Obligor has been signed by the
Obligor in the appropriate spaces. All blanks on any form have been properly
filled in and each form has otherwise been correctly prepared. The complete
Receivable File for each Receivable currently is in the possession of the
Custodian.

     15.  Receivables in Force. No Receivable has 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. No
terms of any Receivable have been waived, altered or modified in any respect
since its origination, except by instruments or documents identified in the
Receivable File. No Receivable has been modified as a result of application of
the Soldiers' and Sailors' Civil Relief Act of 1940, as amended.

     16.  Lawful Assignment. No Receivable was originated in, or is subject to
the laws of, any jurisdiction the laws of which would make unlawful, void or
voidable the sale, transfer and assignment of such Receivable under this
Agreement or pursuant to transfers of the Notes.

     17.  Good Title. Immediately prior to the conveyance of the Receivables to
AFS Funding pursuant to this Agreement or Subsequent Purchase Agreement, as
applicable, AmeriCredit was the sole owner thereof and had good and indefeasible
title thereto, free of any Lien and, upon execution and delivery of this
Agreement by AmeriCredit, AFS Funding shall have good and indefeasible title to
and will be the sole owner of such Receivables, free of any Lien. No Dealer or
Third-Party Lender has a participation in, or other right to receive, proceeds
of any Receivable. AmeriCredit has not taken any action to convey any right to
any Person that would result in such Person having a right to payments received
under the related Insurance Policies or the related Dealer Agreements, Auto Loan
Purchase and Sale Agreements, Dealer Assignments, or Third-Party Lender
Assignments or to payments due under such Receivables.

     18.  Security Interest in Financed Vehicle. Each Receivable created or
shall create a valid, binding and enforceable first priority security interest
in favor of AmeriCredit in the Financed Vehicle. The Lien Certificate and
original certificate of title for each Financed Vehicle show, or if a new or
replacement Lien Certificate is being applied for with respect to such Financed
Vehicle the Lien Certificate will be received within 180 days of the Closing
Date or Subsequent Transfer Date, as applicable, and will show AmeriCredit named
as the original secured party under each Receivable as the holder of a first
priority security interest in such Financed Vehicle. With respect to each
Receivable for which the Lien Certificate has not yet been returned from the
Registrar of Titles, AmeriCredit has applied for or received written evidence
from the related Dealer or Third-Party Lender that such Lien Certificate showing
AmeriCredit as first lienholder has been applied for and AmeriCredit's security
interest has been validly assigned by AmeriCredit to AFS Funding pursuant to
this Agreement. Immediately after the sale, transfer and assignment thereof by
AmeriCredit to AFS Funding, each Receivable will be secured by an enforceable
and perfected first priority security interest in the Financed Vehicle in favor
of AFS Funding as secured party, which security interest is prior to all other
Liens upon and security interests in such Financed Vehicle which now exist or
may hereafter arise or be created (except, as to priority, for any lien for
taxes, labor or materials affecting a Financed Vehicle). As of the related
Cutoff Date there were no Liens or claims for taxes, work, labor or

                                      B-3


<PAGE>

materials affecting a Financed Vehicle which are or may be Liens prior or equal
to the Liens of the related Receivable.

     19.  All Filings Made. All filings (including, without limitation, UCC
filings) required to be made by any Person and actions required to be taken or
performed by any Person in any jurisdiction to give AFS Funding a first priority
perfected lien on, or ownership interest in, the Receivables and the proceeds
thereof and the Other Conveyed Property have been made, taken or performed.

     20.  No Impairment. AmeriCredit has not done anything to convey any right
to any Person that would result in such Person having a right to payments due
under the Receivable or otherwise to impair the rights of the Trust, the
Insurer, the Trustee, the Trust Collateral Agent and the Noteholders in any
Receivable or the proceeds thereof.

     21.  Receivable Not Assumable. No Receivable is assumable by another Person
in a manner which would release the Obligor thereof from such Obligor's
obligations to AmeriCredit with respect to such Receivable.

     22.  No Defenses. No Receivable is subject to any right of rescission,
setoff, counterclaim or defense and no such right has been asserted or
threatened with respect to any Receivable.

     23.  No Default. There has been no default, breach, violation or event
permitting acceleration under the terms of any Receivable (other than payment
delinquencies of not more than 30 days), and no condition exists or event has
occurred and is continuing that with notice, the lapse of time or both would
constitute a default, breach, violation or event permitting acceleration under
the terms of any Receivable, and there has been no waiver of any of the
foregoing. As of the related Cutoff Date no Financed Vehicle had been
repossessed.

     24.  Insurance. At the time of origination of a Receivable by AmeriCredit
or a purchase of a Receivable by AmeriCredit from a Dealer or Third-Party
Lender, each Financed Vehicle is required to be covered by a comprehensive and
collision insurance policy (i) in an amount at least equal to the lesser of (a)
its maximum insurable value or (b) the principal amount due from the Obligor
under the related Receivable, (ii) naming AmeriCredit as loss payee and (iii)
insuring against loss and damage due to fire, theft, transportation, collision
and other risks generally covered by comprehensive and collision coverage. Each
Receivable requires the Obligor to maintain physical loss and damage insurance,
naming AmeriCredit and its successors and assigns as additional insured parties,
and each Receivable permits the holder thereof to obtain physical loss and
damage insurance at the expense of the Obligor if the Obligor fails to do so. No
Financed Vehicle is insured under a policy of Force-Placed Insurance on the
related Cutoff Date.

     25.  Past Due. At the related Cutoff Date no Receivable was more than 30
days past due.

     26.  Remaining Principal Balance. At the related Cutoff Date the Principal
Balance of each Receivable set forth in the Schedules of Receivables is true and
accurate in all material respects.

                                      B-4

     27.  Certain Characteristics of Initial Receivables. (A) Each Initial
Receivable had a remaining maturity, as of the Initial Cutoff Date, of not more
than 72 months; (B) each Initial Receivable had an original maturity of not more
than 72 months; (C) not more than 40% of Receivables (calculated by Aggregate

(F) no Initial Receivable was more than 30 days past due as of the Initial

                                      B-5
