          SECTION 4.1  Protection of Title of Purchaser.
                       ---------------------------------

          (a)  At or prior to the Closing Date, each Seller shall have filed or
     caused to be filed a UCC-1 financing statement, executed by such 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 Texas and in such other locations as
     Purchaser shall have required. At or prior to any Subsequent Transfer Date,
     each Seller shall file or cause to be filed a UCC-1 financing statement
     executed by such 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 Texas
     and in such other locations as Purchaser shall require. From time to time
     thereafter, Sellers 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. Sellers 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 either
     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.

          (b)  Sellers shall not change their name, identity, or corporate
     structure in any manner that would, could or might make any financing
     statement or continuation statement filed by Sellers (or by Purchaser,
     Issuer or the Trust Collateral Agent on behalf of Sellers) in accordance
     with paragraph (a) above seriously misleading within the meaning of (S) 9-
     402(7) of the UCC, unless they shall have given Purchaser, Issuer and the

                                       10

     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)  Sellers 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
     of their principal executive offices, 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. AFS 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, AFS 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, 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. AFS 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, AFS'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 AFS'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 Sellers 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,
     Sellers 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
                       ------------------------

to the Receivables and the Other Conveyed Property against all claims of third
parties claiming through or under Sellers.

                       ------------------

the occurrence of a Repurchase Event, AFS 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, AFS shall deposit the Purchase Amount in

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 AFS to

behalf of 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 AFS to demand
performance hereunder, and in connection therewith, AFS 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
AFS under this Section shall not terminate upon a termination of AFS 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 AFS, AFS 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
AFS under Section 5.1 hereof, Purchaser and the Issuer shall take such steps as
may be reasonably requested by AFS in order to assign to AFS 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 AFS 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 AFS, take such steps as AFS
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 Sellers.  Sellers shall be liable in
                       --------------------
accordance herewith only to the extent of the obligations in this Agreement
specifically undertaken by Sellers and the representations and warranties of
Sellers.

          SECTION 6.2  Merger or Consolidation of Sellers or Purchaser.  Any
                       -----------------------------------------------
corporation or other entity (i) into which Sellers or Purchaser may be merged or
consolidated, (ii) resulting from any merger or consolidation to which Sellers
or Purchaser is a party or (iii) succeeding to the business of Sellers 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 Sellers or Purchaser, as the case may be, under this Agreement and, whether
or not such assumption agreement is executed, shall be the successor to Sellers
or Purchaser, as the case may be, hereunder (without relieving Sellers 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. Sellers 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, 3.2 and 3.3 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) Sellers 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) Sellers
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

                                       15
<PAGE>

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 Sellers and Others.  Sellers
                       ---------------------------------------------
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. Sellers 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  Sellers May Own Notes or the Certificate.  Subject to the
                       ----------------------------------------
provisions of the Sale and Servicing Agreement, Sellers and any Affiliate of
Sellers may in their 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 Sellers or an Affiliate thereof.

          SECTION 6.5  Amendment.
                       ----------

          (a)  This Agreement may be amended by Sellers 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 Sellers
     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 Sellers provide
                                       --------  -------
     the Trust Collateral Agent with an Opinion of Counsel, (which may be
     provided by the Sellers' 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, Sellers
     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

                                       16
<PAGE>

     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.

                       -------

Attention: Chief Financial Officer, or such other address as shall be designated
by a party in a written notice delivered to the other party or to the Issuer,
Owner Trustee or the Trust Collateral Agent, as applicable.

          SECTION 6.7  Merger and Integration. Except as specifically stated
                       ----------------------
otherwise herein, this Agreement and Related Documents set forth the entire
understanding of the parties relating to the subject matter hereof, and all
prior understandings, written or oral, are superseded by this Agreement and the
Related Documents. This Agreement may not be modified, amended, waived or
supplemented except as provided herein.

                       --------------------------
covenants, provisions or terms of this Agreement shall be for any reason
whatsoever held invalid, then such covenants, provisions or terms shall be
deemed severable from the remaining covenants, provisions or terms of this
Agreement and shall in no way affect the validity or enforceability of the other

          SECTION 6.9  Intention of the Parties.  The execution and delivery of

they intend that the assignment and transfer herein contemplated constitute a
sale and assignment outright, and not for security, of the Receivables and the

bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding,
or other proceeding under any federal or state bankruptcy or similar law, or the
occurrence of another similar event, of, or with respect to Sellers. In the
event that such conveyance is determined to be made as security for a loan made
by Purchaser, the Issuer, the Noteholders or the Certificateholder to Sellers,
the parties intend that Sellers shall have granted to Purchaser a security
interest in all of Sellers' right, title and interest in and to the Receivables
and the Other Conveyed Property conveyed pursuant to Section 2.1 hereof, and
that this Agreement shall constitute a security agreement under applicable law.

                       ------------
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.

                       ----------------------------------------------------

waive any further notice thereof and covenant and agree that the representations
and warranties of Sellers contained in this Agreement and the rights of

Trustee, the Trust Collateral Agent, the Noteholders and the Certificateholder.
In furtherance of the foregoing, Sellers covenant and agree to perform their
duties and obligations hereunder, in accordance with the terms hereof for the
benefit of the Insurer, the Issuer, the Owner Trustee, the Trust Collateral
Agent, the Noteholders and the Certificateholder and that, notwithstanding
anything to the contrary in this Agreement, Sellers shall be directly liable to
the Issuer, the Owner Trustee, the Trust Collateral Agent, the Noteholders and
the Certificateholder (notwithstanding any failure by the Servicer, the Backup
Servicer or the Purchaser to perform their respective duties and obligations
hereunder or under Related Documents) and that the Trust Collateral Agent may
enforce the duties and obligations of Sellers under this Agreement against
Sellers for the benefit of the Insurer, the Owner Trustee, the Trust Collateral
Agent, the Noteholders and the Certificateholder.

          SECTION 6.13 Nonpetition Covenant.  Neither Purchaser nor Sellers
                       --------------------
shall petition or otherwise invoke the process of any court or government
authority for the purpose of commencing or sustaining a case against the
Purchaser or the Issuer under any federal or state bankruptcy, insolvency or
similar law or appointing a receiver, liquidator, assignee, trustee, custodian,
sequestrator or other similar official of the Purchaser or the Issuer or any

                       ---------------------------------

             AMERICREDIT FINANCIAL SERVICES, INC. ("AMERICREDIT")
             ----------------------------------------------------

     1.   Characteristics of Receivables.  Each Receivable (A) was originated
          ------------------------------
by a Dealer for the retail sale of a Financed Vehicle in the ordinary course of
such Dealer's business in accordance with AmeriCredit's credit policies and such
Dealer had all necessary licenses and permits to originate Receivables in the
state where such Dealer was located, was fully and properly executed by the
parties thereto, was 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,
(B) contains customary and enforceable provisions such as to render the rights
and remedies of the holder thereof adequate for realization against the
collateral security, (C) 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 (D) 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 by a
          -----------------------------
Dealer and was sold by the Dealer to AmeriCredit and by AmeriCredit either (A)
to AFS Funding Corp. ("AFS Funding") or (B) to CP Funding Corp. ("CP Funding")
and by CP Funding to AFS Funding without any fraud or misrepresentation on the
part of such Dealer 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 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
<PAGE>

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 either AmeriCredit or CP
Funding 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 Schedules 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 either AmeriCredit or CP Funding 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 and New York.

     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) the original executed credit application, or a
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

                                       2
<PAGE>

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, either AmeriCredit or CP Funding 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 both AmeriCredit and CP Funding, AFS Funding shall
have good and indefeasible title to and will be the sole owner of such
Receivables, free of any Lien.  No Dealer has a participation in, or other right
to receive, proceeds of any Receivable.  Neither AmeriCredit nor CP Funding has
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 or Dealer 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 either AmeriCredit or CP Funding  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 received written evidence
from the related Dealer that such Lien Certificate showing AmeriCredit as first
lienholder has been applied for and AmeriCredit's security interest has been
validly assigned by AmeriCredit either (A) to AFS Funding or (B) to CP Funding
and by CP Funding to AFS Funding pursuant to this Agreement.  Immediately after
the sale, transfer and assignment thereof by either AmeriCredit or CP Funding 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 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.  Neither AmeriCredit nor CP Funding have 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 a purchase of a Receivable by AmeriCredit
          ---------
from a Dealer, 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.

     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 Receivable had an original maturity of not more than 72
months; (C) each Initial Receivable had a remaining Principal Balance as of the
Initial Cutoff Date of at least $250 and not more than $60,000; (D) each Initial
Receivable has an Annual Percentage Rate of at least 8% and not more than 32%;
(E) no Initial Receivable was more than 30 days past due as of the Initial
Cutoff Date and (F) no funds have been advanced by AmeriCredit, any Dealer, or
anyone acting on behalf of any of them in order to cause any Initial Receivable
to qualify under clause (E) above.

                 --------------------------------------------------------
Security. Financial Security represents, warrants and agrees as follows:
--------

          (a)  Organization, Etc.  Financial Security is a stock insurance
               -----------------
     company duly organized, validly existing and authorized to transact
     financial guaranty insurance business under the laws of the State of New
     York.

          (b)  Authorization, Etc.  The Policy and the Financial Security
               ------------------
     Agreements have been duly authorized, executed and delivered by Financial
     Security.

          (c)  Validity, Etc.  The Policy and the Financial Security Agreements
               -------------
      constitute valid and binding obligations of Financial Security,
     enforceable against Financial Security in accordance with their terms,
     subject, as to the enforcement of remedies, to bankruptcy, insolvency,
     reorganization, rehabilitation, moratorium and other similar laws affecting
     the enforceability of creditors' rights generally applicable in the event
     of the bankruptcy or insolvency of Financial Security and to the
     application of general principles of equity and subject, in the case of
     this Agreement, to principles of public policy limiting the right to
     enforce the indemnification provisions contained herein.

          (d)  Exemption From Registration.  The Policy is exempt from
               ---------------------------
     registration under the Securities Act.

          (e)  No Conflicts.  Neither the execution or delivery by Financial
               ------------
     Security of the Policy or the Financial Security Agreements, nor the
     performance by Financial Security of its obligations thereunder, will
     conflict with any provision of the certificate of incorporation or the
     bylaws of Financial Security nor result in a breach of, or constitute a
     default under, any material agreement or other instrument to which
     Financial Security is a party or by which any of its property is bound nor
     violate any judgment, order or decree applicable to Financial Security of
     any governmental or regulatory body, administrative agency, court or
     arbitrator having jurisdiction over Financial Security (except that, in the
     published opinion of the Securities and Exchange Commission, the
     indemnification provisions of this Agreement, insofar as they relate to
     indemnification for liabilities arising under the Securities Act, are
     against public policy as expressed in the Securities Act and are therefore
     unenforceable).

          (f)  Financial Information.  The consolidated balance sheets of
               ---------------------
     Financial Security as of December 31, 1998 and December 31, 1997 and the
     related consolidated statements of income, changes in shareholder's equity
     and cash flows for the fiscal years then ended, and the interim
     consolidated balance sheet of Financial Security as of September 30, 1999,
     and the related statements of income, changes in shareholder equity

                                       3
<PAGE>

     and cash flows for the interim period then ended, which are incorporated by
     reference in the Prospectus, fairly present in all material respects the
     financial condition of Financial Security as of such dates and for such
     periods in accordance with generally accepted accounting principles
     consistently applied (subject as to interim statements to normal year-end
     adjustments) and since the date of the most current interim consolidated
     balance sheet referred to above there has been no change in the financial
     condition of Financial Security which would materially and adversely affect
     its ability to perform its obligations under the Policy.

          (g)  Financial Security Information. The information in the Prospectus
               ------------------------------
     Supplement set forth under the caption "The Insurer" (as revised from time
     to time in accordance with the provisions hereof, the "Financial Security
                                                            ------------------
     Information") is limited and does not purport to provide the scope of
     -----------
     disclosure required to be included in a prospectus with respect to a
     registrant in connection with the offer and sale of securities of such
     registrant registered under the Securities Act.  Within such limited scope
     of disclosure, however, as of the date of the Prospectus Supplement and as
     of the date hereof, the Financial Security Information does not contain any
     untrue statement of a material fact, or omit to state a material fact
     necessary to make the statements contained therein, in the light of the
     circumstances under which they were made, not misleading.

          (h)  Additional Information.  Financial Security will furnish to the
               ----------------------
     Underwriters or the Seller, upon request of the Underwriters or the Seller,
     as the case may be, copies of Financial Security's most recent financial
     statements (annual or interim, as the case may be) which fairly present in
     all material respects the financial condition of Financial Security as of
     the dates and for the periods indicated, in accordance with generally
     accepted accounting principles consistently applied except as noted therein
     (subject, as to interim statements, to normal year-end adjustments).  In
     addition, if the delivery of a Prospectus relating to the Securities is
     required at any time prior to the expiration of nine months after the time
     of issue of the Prospectus in connection with the offering or sale of the
     Securities, the Seller or the Underwriters will notify Financial Security
     of such requirement to deliver a Prospectus and Financial Security will
     promptly provide the Underwriters and the Seller with any revisions to the
     Financial Security Information that are in the judgment of Financial
     Security necessary to prepare an amended Prospectus or a supplement to the
     Prospectus.

          (i)  Opinion of Counsel.  Financial Security will furnish to the
               ------------------
     Underwriters and the Seller on the closing date for the sale of the
     Securities an opinion of its Assistant General Counsel, to the effect set
     forth in Exhibit A attached hereto, dated such closing date and addressed
     to the Seller and the Underwriters.

          (j)  Consents and Reports of Independent Accountants.  Financial
               -----------------------------------------------
     Security will furnish to the Underwriters and the Seller, upon request, as
     comfort from its independent accountants in respect of its financial
     condition, (i) at the expense of the Person specified in the Insurance
     Agreement, a copy of the Prospectus, including either a manually signed
     consent or a manually signed report of Financial Security's independent
     accountants and (ii) the quarterly review letter by Financial Security's
     independent

                                       4
<PAGE>

     accountants in respect of the most recent interim financial statements of
     Financial Security.

Nothing in this Agreement shall be construed as a representation or warranty by
Financial Security concerning the rating of its insurance financial strength by
Moody's Investors Service, Inc., its insurer financial strength by Standard &
Poor's Ratings Services and Standard & Poor's (Australia) Pty. Ltd., its claims-
paying ability by Fitch IBCA, Inc. and Japan Rating and Investment Information,
Inc. or any other rating assigned by a rating agency (collectively, the "Rating
                                                                         ------
Agencies").  The Rating Agencies, in assigning such ratings, take into account
--------
facts and assumptions not described in the Prospectus and the facts and
assumptions which are considered by the Rating Agencies, and the ratings issued
thereby, are subject to change over time.

     Section 3.  Representations, Warranties and Agreements of the Underwriters.
                 --------------------------------------------------------------
Each of the Underwriters represents, warrants and agrees as follows:

          (a)  Compliance With Laws.  Such Underwriter will comply in all
               --------------------
     material respects with all legal requirements in connection with offers and
     sales of the Securities and make such offers and sales in the manner
     provided in the Prospectus.

          (b)  Offering Document.  Such Underwriter will not use, or distribute
               -----------------
     to other broker-dealers for use, any Offering Document in connection with
     the offer and sale of the Securities unless such Offering Document includes
     such information as has been furnished by Financial Security for inclusion
     therein and the information therein concerning Financial Security has been
     approved by Financial Security in writing. Financial Security hereby
     consents to the information in respect of Financial Security included in
     the Prospectus. Each Offering Document will include the following
     statement:

          "The Policy is not covered by the property/casualty
          insurance security fund specified in Article 76 of
          the New York Insurance Law".

     Each Offering Document including financial information with respect to
     Financial Security prepared in accordance with generally accepted
     accounting principles (but excluding any Offering Document in which such
     financial statements are incorporated by reference) will include the
     following statement immediately preceding such financial information:

          "The New York State Insurance Department recognizes
          only statutory accounting practices for determining
          and reporting the financial condition and results of
          operations of an insurance company, for determining
          its solvency under the New York Insurance Law, and for
          determining whether its financial condition warrants
          the payment of a dividend to its stockholders.  No
          consideration is given by the New York State Insurance
          Department to financial statements prepared in
          accordance with

                                       5
<PAGE>

          generally accepted accounting principles in making
          such determinations."

          (c)    Underwriter Information.  All material provided by the
                 -----------------------
     Underwriters for inclusion in the Prospectus (as revised from time to time,
     the "Underwriter Information"), insofar as such information relates to the
          -----------------------
     Underwriters, is true and correct in all material respects. In respect of
     the Prospectus Supplement, the Underwriter Information is limited to the
     information set forth (i) on the cover page of the Prospectus Supplement in
     the table containing the price to the public, the underwriting discount and
     the proceeds to the Seller with respect to the Securities and (ii) in the

                 ---------------

          (a)    Financial Security agrees, upon the terms and subject to the
     conditions provided herein, to indemnify, defend and hold harmless each
     Seller Party and each Underwriter Party against (i) any and all Losses
     incurred by them with respect to the offer and sale of the Securities and
     resulting from Financial Security's breach of any of its representations,
     warranties or agreements set forth in Section 2 hereof and (ii) any and all
     Losses to which any Seller Party or Underwriter Party may become subject,
     under the Securities Act or otherwise, insofar as such Losses arise out of
     or result from an untrue statement of a material fact contained in any
     Offering Document or the omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading, in each case to the extent, but only to the extent, that such
     untrue statement or omission was made in the Financial Security Information
     included therein in accordance with the provisions hereof.

          (b)    Each of the Underwriters, agrees, upon the terms and subject to
     the conditions provided herein, to indemnify, defend and hold harmless each
     Financial Security Party and each Seller Party against (i) any and all
     Losses incurred by them with respect to the offer and sale of the
     Securities and resulting from the Underwriters' breach of any of its
     representations, warranties or agreements set forth in Section 3 hereof and
     (ii) any and all Losses to which any Financial Security Party or Seller
     Party may become subject, under the Securities Act or otherwise, insofar as
     such Losses arise out of or result from an untrue statement of a material
     fact contained in any Offering Document or the omission to state therein a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, in each case to the extent, but only to
     the extent, that such untrue statement or omission was made in the
     Underwriter Information included therein.

          (c)    Upon the incurrence of any Losses for which a party is entitled
     to indemnification hereunder, the Indemnifying Party shall reimburse the
     Indemnified Party promptly upon establishment by the Indemnified Party to
     the Indemnifying Party of the Losses incurred.

     Section 5.  Indemnification Procedures.  Except as provided below in
                 --------------------------
Section 6 with respect to contribution, the indemnification provided herein by
an Indemnifying Party shall be

                                       6
<PAGE>

the exclusive remedy of any and all Indemnified Parties for the breach of a
representation, warranty or agreement hereunder by an Indemnifying Party;
provided, however, that each Indemnified Party shall be entitled to pursue any
--------  -------
other remedy at law or in equity for any such breach so long as the damages
sought to be recovered shall not exceed the Losses incurred thereby resulting
from such breach. In the event that any action or regulatory proceeding shall be
commenced or claim asserted which may entitle an Indemnified Party to be
indemnified under this Agreement, such party shall give the Indemnifying Party
written or telegraphic notice of such action or claim reasonably promptly after
receipt of written notice thereof. The Indemnifying Party shall be entitled to
participate in and, upon notice to the Indemnified Party, assume the defense of
any such action or claim in reasonable cooperation with, and with the reasonable
cooperation of, the Indemnified Party. The Indemnified Party will have the right
to employ its own counsel in any such action in addition to the counsel of the
Indemnifying Party, but the fees and expenses of such counsel will be at the
expense of such Indemnified Party, unless (a) the employment of counsel by the
Indemnified Party at its expense has been authorized in writing by the
Indemnifying Party, (b) the Indemnifying Party has not in fact employed counsel
satisfactory to Financial Security to assume the defense of such action within a
reasonable time after receiving notice of the commencement of the action, or (c)
the named parties to any such action or proceeding (including any impleaded
parties) include both the Indemnifying Party and one or more Indemnified
Parties, and the Indemnified Parties shall have been advised by counsel that (A)
there may be one or more legal defenses available to them which are different
from or additional to those available to the Indemnifying Party and (B) the
representation of the Indemnifying Party and such Indemnified Parties by the
same counsel would be inappropriate or contrary to prudent practice (in which
case, if such Indemnified Parties notify the Indemnifying Party in writing that
they elect to employ separate counsel at the expense of the Indemnifying Party,
the Indemnifying Party shall not have the right to assume the defense of such
action or proceeding on behalf of such Indemnified Parties, it being understood,
however, that the Indemnifying Party shall not, in connection with any one such
action or proceeding or separate but substantially similar or related actions or
proceedings in the same jurisdiction arising out of the same general allegations
or circumstances, be liable for the reasonable fees and expenses of more than
one separate firm of attorneys at any time for all Seller Parties, one such firm
for all Underwriter Parties and one such firm for all Financial Security
Parties, as the case may be, which firm shall be designated in writing by the
Seller in respect of the Seller Parties, by the Underwriters in respect of the
Underwriter Parties and by Financial Security in respect of the Financial
Security Parties), in each of which cases the fees and expenses of counsel will
be at the expense of the Indemnifying Party and all such fees and expenses will
be reimbursed promptly as they are incurred. The Indemnifying Party shall not be
liable for any settlement of any such claim or action unless the Indemnifying
Party shall have consented thereto or be in default in its obligations
hereunder. Any failure by an Indemnified Party to comply with the provisions of
this Section shall relieve the Indemnifying Party of liability only if such
failure is prejudicial to the position of the Indemnifying Party and then only
to the extent of such prejudice.

     Section 6.  Contribution.
                 ------------

          (a)    To provide for just and equitable contribution if the
     indemnification provided by any Indemnifying Party is determined to be
     unavailable for any Indemnified Party (other than due to application of
     this Section), each Indemnifying Party shall

                                       7
<PAGE>

     contribute to the Losses arising from any breach of any of its
     representations, warranties or agreements contained in this Agreement on
     the basis of the relative fault of each of the parties as set forth in
     Section 6(b) below; provided, however, that an Indemnifying Party shall in
                         --------  -------
     no event be required to contribute to all Indemnified Parties an aggregate
     amount in excess of the Losses incurred by such Indemnified Parties
     resulting from the breach of representations, warranties or agreements
     contained in this Agreement.

          (b)    The relative fault of each Indemnifying Party, on the one hand,
     and of each Indemnified Party, on the other, shall be determined by
     reference to, among other things, whether the breach of, or alleged breach
     of, any representations, warranties or agreements contained in this
     Agreement relates to information supplied by, or action within the control
     of, the Indemnifying Party or the Indemnified Party and the parties'
     relative intent, knowledge, access to information and opportunity to
     correct or prevent such breach.

          (c)    The parties agree that Financial Security shall be solely
     responsible for the Financial Security Information and the Underwriters
     shall be solely responsible for the Underwriter Information and that the
     balance of each Offering Document shall be the responsibility of the
     Seller.

          (d)    Notwithstanding anything in this Section 6 to the contrary, the
     Underwriters shall not be required to contribute an amount in excess of the
     amount by which the total price of the Securities underwritten by the
     Underwriters exceeds the amount of any damages that the Underwriters have
     otherwise been required to pay in respect of such untrue statement or
     omission.

          (e)    No person guilty of fraudulent misrepresentation (within the
     meaning of Section 11(f) of the Securities Act) shall be entitled to
     contribution from any person who was not guilty of such fraudulent
     misrepresentation.

          (f)    Upon the incurrence of any Losses entitled to contribution
     hereunder, the contributor shall reimburse the party entitled to
     contribution promptly upon establishment by the party entitled to
     contribution to the contributor of the Losses incurred.

     Section 7.  Miscellaneous.

                                   EXHIBIT A

                     OPINION OF ASSISTANT GENERAL COUNSEL

     Based upon the foregoing, I am of the opinion that:

     1.   Financial Security is a stock insurance company duly organized,
validly existing and authorized to transact financial guaranty insurance
business under the laws of the State of New York.

     2.   The Policy and the Financial Security Agreements have been duly
authorized, executed and delivered by Financial Security.

     3.   The Policy and the Financial Security Agreements constitute valid and
binding obligations of Financial Security, enforceable against Financial
Security in accordance with their terms, subject, as to the enforcement of
remedies, to bankruptcy, insolvency, reorganization, rehabilitation, moratorium
and other similar laws affecting the enforceability of creditors' rights
generally applicable in the event of the bankruptcy or insolvency of Financial
Security and to the application of general principles of equity and subject, in
the case of the Indemnification Agreement, to principles of public policy
limiting the right to enforce the indemnification provisions contained therein
insofar as they relate to indemnification for liabilities arising under
applicable securities laws.

     4.  The Policy is exempt from registration under the Securities Act of
1933, as amended (the "Act").
                       ---

     5.  Neither the execution or delivery by Financial Security of the Policy
or the Financial Security Agreements, nor the performance by Financial Security
of its obligations thereunder, will conflict with any provision of the
certificate of incorporation or the bylaws of Financial Security or violate any
law or regulation, which violation would impair the binding effect or
enforceability of the Policy or any of the Agreements or, to the best of my
knowledge, result in a breach of, or constitute a default under, any agreement
or other instrument to which Financial Security is a party or by which it or any
of its property is bound or, to the best of my knowledge, violate any judgment,
order or decree applicable to Financial Security of any governmental or
regulatory body, administrative agency, court or arbitrator having jurisdiction
over Financial Security (except that in the published opinion of the Securities
and Exchange Commission the indemnification provisions of the Indemnification
Agreement, insofar as they relate to indemnification for liabilities arising
under the Act, are against public policy as expressed in the Act and are
therefore unenforceable).

     In addition, please be advised that I have reviewed the description of
Financial Security under the caption "The Insurer" in the Prospectus (the
"Offering Document") of the Seller with respect to the Securities.  The
 -----------------
information provided in the Offering Document with respect to Financial Security
is limited and does not purport to provide the scope of disclosure required to
be included in a prospectus with respect to a registrant under the Act in
connection with the

                                      A-1
<PAGE>

public offer and sale of securities of such registrant. Within such limited
scope of disclosure, however, there has not come to my attention any information
which would cause me to believe that the description of Financial Security
referred to above, as of the date of the Offering Document or as of the date of
this opinion, contained or contains any untrue statement of a material fact or
omitted or omits to state a material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading (except that I express no opinion with respect to any financial
statements or other financial information contained or referred to therein).
