               --------------
pending or, to its knowledge threatened against it before any court, regulatory
body, administrative agency or other tribunal or governmental instrumentality
having jurisdiction over it or its properties (A) asserting the invalidity of
this Agreement or any of the Basic Documents, (B) seeking to prevent the

          SECTION 2.10. Covenants of the Certificateholder.  The
                        ----------------------------------
Certificateholder agrees:

          (a)  to be bound by the terms and conditions of the Certificate of
which the Holder is the beneficial owner and of this Agreement, including any
supplements or amendments hereto and to perform the obligations of a Holder as
set forth therein or herein, in all respects as if it were a signatory hereto.
This undertaking is made for the benefit of the Trust, the Owner Trustee and the
Security Insurer; and

          (b)  until the completion of the events specified in Section 8.1(d),
not to, for any reason, institute proceedings for the Trust to be adjudicated a
bankrupt or insolvent, or consent to the institution of bankruptcy or insolvency
proceedings against the Trust, or file a petition seeking or consenting to
reorganization or relief under any applicable federal or state law relating to
bankruptcy, or consent to the appointment of a receiver, liquidator, assignee,
trustee, sequestrator (or other similar official) of the Trust or a substantial
part of its property, or cause or permit the Trust to make any assignment for
the benefit of its creditors, or admit in writing its inability to pay its debts
generally as they become due, or declare or effect a moratorium on its debt or
take any action in furtherance of any such action.

          SECTION 2.11. Federal Income Tax Treatment of the Trust.
                        ------------------------------------------

          (a)  For so long as the Trust has a single owner for federal income
tax purposes, it will, pursuant to Treasury Regulations promulgated under
section 7701 of the Code, be disregarded as an entity distinct from the
Certificateholder for all federal income tax purposes. Accordingly, for federal
income tax purposes, the Certificateholder will be treated as (i) owning all
assets owned by the Trust, (ii) having incurred all liabilities incurred by the
Trust, and (iii) all transactions between the Trust and the Certificateholder
will be disregarded.

          (b)  Neither the Owner Trustee nor any Certificateholder will, under
any circumstances, and at any time, make an election on IRS Form 8832 or
otherwise, to classify the Trust as an association taxable as a corporation for
federal, state or any other applicable tax purpose.

          (c)  In the event that the Trust has two equity owners for federal
income tax purposes, the Trust will be treated as a partnership. At any such
time that the Trust has two

                                       7
<PAGE>

equity owners, this Agreement will be amended, in accordance with Section 10.1
herein, and appropriate provisions will be added so as to provide for treatment
of the Trust as a partnership.

                                 ARTICLE III.

                     Certificate and Transfer of Interest
                     ------------------------------------

          SECTION 3.1. Initial Ownership. Upon the formation of the Trust by the
                       -----------------
contribution by the Depositor pursuant to Section 2.5 and until the issuance of
the Certificate to the initial Certificateholder, the Depositor shall be the
sole beneficiary of the Trust.

          SECTION 3.2. The Certificate. The Certificate shall be executed on
                       ---------------
behalf of the Trust by manual or facsimile signature of an authorized officer of
the Owner Trustee. A Certificate bearing the manual or facsimile signatures of
individuals who were, at the time when such signatures shall have been affixed,
authorized to sign on behalf of the Trust, shall be validly issued and entitled
to the benefit of this Agreement, notwithstanding that such individuals or any
of them shall have ceased to be so authorized prior to the authentication and
delivery of such Certificate or did not hold such offices at the date of
authentication and delivery of such Certificate. A transferee of a Certificate
shall become a Certificateholder, and shall be entitled to the rights and
subject to the obligations of a Certificateholder hereunder, upon due
registration of such Certificate in such transferee's name pursuant to Section
3.4.

          SECTION 3.3. Authentication of Certificate. Concurrently with the
                       -----------------------------
initial sale of the Receivables to the Trust pursuant to the Sale and Servicing
Agreement, the Owner Trustee shall cause the Certificate to be executed on
behalf of the Trust, authenticated and delivered to or upon the written order of
the Depositor, signed by its chairman of the board, its president or any vice
president, its treasurer or any assistant treasurer without further corporate
action by the Depositor, in authorized denominations. No Certificate shall
entitle its holder to any benefit under this Agreement, or shall be valid for
any purpose, unless there shall appear on such Certificate a certificate of
authentication substantially in the form set forth in Exhibit A, executed by the
Owner Trustee or Bankers Trust Company as the Owner Trustee's authentication
agent, by manual signature; such authentication shall constitute conclusive
evidence that such Certificate shall have been duly authenticated and delivered
hereunder. The Certificate shall be dated the date of its authentication.

          SECTION 3.4. Registration of Transfer and Exchange of Certificate. The
                       ----------------------------------------------------
Certificate Registrar shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 3.7, a Certificate Register in which, subject to
such reasonable regulations as it may prescribe, the Owner Trustee shall provide
for the registration of the Certificate and of transfers and exchanges of the
Certificate as herein provided. Bankers Trust Company shall be the initial
Certificate Registrar.

          The Certificate Registrar shall provide the Trust Collateral Agent
with the name and address of the Certificateholder on the Closing Date.  Upon
any transfers of the Certificate, the Certificate Registrar shall notify the
Trust Collateral Agent of the name and address of the transferee in writing, by
facsimile, on the day of such transfer.

                                       8
<PAGE>

          Upon surrender for registration of transfer of the Certificate at the
office or agency maintained pursuant to Section 3.7, the Owner Trustee shall
execute, authenticate and deliver (or shall cause Bankers Trust Company as its
authenticating agent to authenticate and deliver), in the name of the designated
transferee, a new Certificate dated the date of authentication by the Owner
Trustee or any authenticating agent.

          A Certificate presented or surrendered for registration of transfer or
exchange shall be accompanied by a written instrument of transfer in form
satisfactory to the Owner Trustee and the Certificate Registrar duly executed by
the Certificateholder or his attorney duly authorized in writing, with such
signature guaranteed by an "eligible guarantor institution" meeting the
requirements of the Certificate Registrar, which requirements include membership
or participation in the Securities Transfer Agent's Medallion Program ("STAMP")
or such other "signature guarantee program" as may be determined by the
Certificate Registrar in addition to, or in substitution for, STAMP, all in
accordance with the Exchange Act.  Each Certificate surrendered for registration
of transfer or exchange shall be canceled and subsequently disposed of by the
Owner Trustee in accordance with its customary practice.

          No service charge shall be made for any registration of transfer or
exchange of the Certificate, but the Owner Trustee or the Certificate Registrar
may require payment of a sum sufficient to cover any tax or governmental charge
that may be imposed in connection with any transfer or exchange of the
Certificate.

          SECTION 3.5. Mutilated, Destroyed, Lost or Stolen Certificates. If (a)
                       -------------------------------------------------
any mutilated Certificate shall be surrendered to the Certificate Registrar, or
if the Certificate Registrar shall receive evidence to its satisfaction of the
destruction, loss or theft of any Certificate and (b) there shall be delivered
to the Certificate Registrar, the Owner Trustee and (unless an Insurer Default
shall have occurred and be continuing) the Security Insurer, such security or
indemnity as may be required by them to save each of them harmless, then in the
absence of notice that such Certificate shall have been acquired by a bona fide
purchaser, the Owner Trustee on behalf of the Trust shall execute and the Owner
Trustee, or Bankers Trust Company, as the Owner Trustee's authenticating agent,
shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
class, tenor and denomination. In connection with the issuance of any new
Certificate under this Section, the Owner Trustee or the Certificate Registrar
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith. Any duplicate
Certificate issued pursuant to this Section shall constitute conclusive evidence
of an ownership interest in the Trust, as if originally issued, whether or not
the lost, stolen or destroyed Certificate shall be found at any time.

          SECTION 3.6. Persons Deemed Certificateholders. Every Person by virtue
                       ---------------------------------
of becoming a Certificateholder in accordance with this Agreement shall be
deemed to be bound by the terms of this Agreement. Prior to due presentation of
the Certificate for registration of transfer, the Owner Trustee, the Certificate
Registrar and the Security Insurer and any agent of the Owner Trustee, the
Certificate Registrar and the Security Insurer, may treat the person in whose
name any Certificate shall be registered in the Certificate Register as the
owner of such Certificate for the purpose of receiving distributions pursuant to
the Sale and Servicing Agreement and for all other purposes whatsoever, and none
of the Owner Trustee, the Certificate

                                       9
<PAGE>

Registrar or the Security Insurer nor any agent of the Owner Trustee, the
Certificate Registrar or the Security Insurer shall be bound by any notice to
the contrary.

          SECTION 3.7. Maintenance of Office or Agency. The Owner Trustee shall
                       -------------------------------
maintain in New York, an office or offices or agency or agencies where the
Certificate may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Owner Trustee in respect of the
Certificate and the Basic Documents may be served. The Owner Trustee initially
designates Bankers Trust Company, 4 Albany Street, New York, New York 10006, as
its principal corporate trust office for such purposes. The Owner Trustee shall
give prompt written notice to the Depositor, the Certificateholder and (unless
an Insurer Default shall have occurred and be continuing) the Security Insurer
of any change in the location of the Certificate Register or any such office or
agency.

          SECTION 3.8. Disposition in Whole But Not in Part. The Certificate may
                       ------------------------------------
be transferred in whole but not in part. Any attempted transfer of the
Certificate that would divide the ownership of the Trust Estate shall be void.
The Certificate is only transferable (i) to an Affiliate of AmeriCredit Corp.
whose stock has been pledged to the Security Insurer or (ii) to another entity
with the prior written consent of the Security Insurer in its sole discretion.
The Owner Trustee shall cause any Certificate issued to contain a legend stating
"THIS CERTIFICATE IS NOT TRANSFERABLE, EXCEPT UNDER THE LIMITED CONDITIONS
SPECIFIED IN THE TRUST AGREEMENT".

          SECTION 3.9. ERISA Restrictions. The Certificate may not be acquired
                       ------------------
by or for the account of (i) an employee benefit plan (as defined in Section
3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) that is subject to the provisions of Title I of ERISA, (ii) a plan
(as defined in Section 4975(e)(1) of the Code) that is subject to Section 4975
of the Code, or (iii) any entity whose underlying assets include assets of a
plan described in (i) or (ii) above by reason of such plan's investment in the
entity (each, a "Benefit Plan"). By accepting and holding its beneficial
ownership interest in its Certificate, the Holder thereof shall be deemed to
have represented and warranted that it is not a Benefit Plan.

                                  ARTICLE IV.

                        Voting Rights and Other Actions
                        -------------------------------

          SECTION 4.1. Prior Notice to Holder with Respect to Certain Matters.
                       ------------------------------------------------------
With respect to the following matters, the Owner Trustee shall not take action
unless at least 30 days before the taking of such action, the Owner Trustee
shall have notified the Certificateholder in writing of the proposed action and
the Certificateholder shall not have notified the Owner Trustee in writing prior
to the 30th day after such notice is given that the Certificateholder has
withheld consent or provided alternative direction:

          (a)  the election by the Trust to file an amendment to the Certificate
of Trust (unless such amendment is required to be filed under the Business Trust
Statute or unless such amendment would not materially and adversely affect the
interests of the Holder);

                                       10
<PAGE>

          (b)  the amendment of the Indenture by a supplemental indenture in
circumstances where the consent of any Noteholder is required;

          (c)  the amendment of the Indenture by a supplemental indenture in
circumstances where the consent of any Noteholder is not required and such
amendment materially adversely affects the interest of the Certificateholder; or

          (d)  except pursuant to Section 12.1(b) of the Sale and Servicing
Agreement, the amendment, change or modification of the Sale and Servicing
Agreement, except to cure any ambiguity or defect or to amend or supplement any
provision in a manner that would not materially adversely affect the interests
of the Certificateholder.

The Owner Trustee shall notify the Certificateholder in writing of any
appointment of a successor Note Registrar or Trust Collateral Agent within five
Business Days after receipt of notice thereof.

          SECTION 4.2. Action by Certificateholder with Respect to Certain
                       ---------------------------------------------------
Matters. The Owner Trustee shall not have the power, except upon the direction
-------
of the Certificateholder or the Security Insurer in accordance with the Basic
Documents, to (a) remove the Servicer under the Sale and Servicing Agreement
pursuant to Section 9.2 thereof or (b) except as expressly provided in the Basic
Documents, sell the Receivables after the termination of the Indenture. The
Owner Trustee shall take the actions referred to in the preceding sentence only
upon written instructions signed by the Certificateholder and the furnishing of
indemnification satisfactory to the Owner Trustee by the Certificateholder.

          SECTION 4.3. Restrictions on Certificateholder's Power.
                       -----------------------------------------

          (a)  The Certificateholder shall not direct the Owner Trustee to take
or refrain from taking any action if such action or inaction would be contrary
to any obligation of the Trust or the Owner Trustee under this Agreement or any
of the Basic Documents or would be contrary to Section 2.3 nor shall the Owner
Trustee be obligated to follow any such direction, if given.

          (b)  The Certificateholder shall not have any right by virtue or by
availing itself of any provisions of this Agreement to institute any suit,
action, or proceeding in equity or at law upon or under or with respect to this
Agreement or any Basic Document, unless the Certificateholder is the Instructing
Party pursuant to Section 5.3 and unless the Certificateholder previously shall
have given to the Owner Trustee a written notice of default and of the
continuance thereof, as provided in this Agreement, and also unless
Certificateholder shall have made written request upon the Owner Trustee to
institute such action, suit or proceeding in its own name as Owner Trustee under
this Agreement and shall have offered to the Owner Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Owner Trustee, for 30 days after its
receipt of such notice, request, and offer of indemnity, shall have neglected or
refused to institute any such action, suit, or proceeding, and during such 30-
day period no request or waiver inconsistent with such written request has been
given to the Owner Trustee pursuant to and in compliance with this Section or
Section 5.3. For the protection and enforcement of the provisions of this
Section, the

Certificateholder and the Owner Trustee shall be entitled to such relief as can
be given either at law or in equity.

          SECTION 4.4. Rights of Security Insurer. Notwithstanding anything to
                       --------------------------
the contrary in the Basic Documents, without the prior written consent of the
Security Insurer (so long as no Insurer Default shall have occurred and be
continuing), the Owner Trustee shall not (i) remove the Servicer, (ii) initiate
any claim, suit or proceeding by the Trust or compromise any claim, suit or
proceeding brought by or against the Trust, other than with respect to the
enforcement of any Receivable or any rights of the Trust thereunder, (iii)
authorize the merger or consolidation of the Trust with or into any other
business trust or other entity (other than in accordance with Section 3.10 of
the Indenture) or (iv) amend the Certificate of Trust.

                                  ARTICLE V.

                     Authority and Duties of Owner Trustee
                     -------------------------------------

          SECTION 5.1. General Authority.
                       -----------------

          (a)  The Owner Trustee is authorized and directed to execute and
deliver the Basic Documents to which the Trust is named as a party and each
certificate or other document attached as an exhibit to or contemplated by the
Basic Documents to which the Trust is named as a party and any amendment
thereto, in each case, in such form as the Depositor shall approve as evidenced
conclusively by the Owner Trustee's execution thereof, and on behalf of the
Trust, to direct the Indenture Trustee to authenticate and deliver Class A-1
Notes in the aggregate principal amount of $192,000,000, Class A-2 Notes in the

principal amount of $275,000,000 and Class A-4 Notes in the aggregate principal
amount of $340,000,000. In addition to the foregoing, the Owner Trustee is
authorized, but shall not be obligated, to take all actions required of the
Trust pursuant to the Basic Documents. The Owner Trustee is further authorized
from time to time to take such action as the Instructing Party recommends with
respect to the Basic Documents so long as such activities are consistent with
the terms of the Basic Documents.

          (b)  The Owner Trustee shall sign on behalf of the Trust any
applicable tax returns of the Trust, unless applicable law requires a
Certificateholder to sign such documents.

          SECTION 5.2. General Duties. It shall be the duty of the Owner Trustee
                       --------------
to discharge (or cause to be discharged) all of its responsibilities pursuant to
the terms of this Agreement and the Sale and Servicing Agreement and to
administer the Trust in the interest of the Holder, subject to the Basic
Documents and in accordance with the provisions of this Agreement.
Notwithstanding the foregoing, the Owner Trustee shall be deemed to have
discharged its duties and responsibilities hereunder and under the Basic
Documents to the extent the Servicer has agreed in the Sale and Servicing
Agreement to perform any act or to discharge any duty of the Trust or the Owner
Trustee hereunder or under any Basic Document, and the Owner Trustee shall not
be liable for the default or failure of the Servicer to carry out its
obligations under the Sale and Servicing Agreement.

<PAGE>

          SECTION 5.3. Action upon Instruction.
                       -----------------------

          (a)  Subject to Article IV and the terms of the Spread Account
Agreement, the Security Insurer (so long as an Insurer Default shall not have
occurred and be continuing) or the Certificateholder (if an Insurer Default
shall have occurred and be continuing) (the "Instructing Party") shall have the
exclusive right to direct the actions of the Owner Trustee in the management of
the Trust, so long as such instructions are not inconsistent with the express
terms set forth herein or in any Basic Document. The Instructing Party shall not
instruct the Owner Trustee in a manner inconsistent with this Agreement or the
Basic Documents.

          (b)  The Owner Trustee shall not be required to take any action
hereunder or under any Basic Document if the Owner Trustee shall have reasonably
determined, or shall have been advised by counsel, that such action is likely to
result in liability on the part of the Owner Trustee or is contrary to the terms
hereof or of any Basic Document or is otherwise contrary to law.

          (c)  Whenever the Owner Trustee is unable to decide between
alternative courses of action permitted or required by the terms of this
Agreement or any Basic Document, the Owner Trustee shall promptly give notice
(in such form as shall be appropriate under the circumstances) to the
Instructing Party requesting instruction as to the course of action to be
adopted, and to the extent the Owner Trustee acts in good faith in accordance
with any written instruction of the Instructing Party received, the Owner
Trustee shall not be liable on account of such action to any Person. If the
Owner Trustee shall not have received appropriate instruction within ten days of
such notice (or within such shorter period of time as reasonably may be
specified in such notice or may be necessary under the circumstances) it may,
but shall be under no duty to, take or refrain from taking such action, not
inconsistent with this Agreement or the Basic Documents, as it shall deem to be
in the best interests of the Certificateholder, and shall have no liability to
any Person for such action or inaction.

          (d)  In the event that the Owner Trustee is unsure as to the
application of any provision of this Agreement or any Basic Document or any such
provision is ambiguous as to its application, or is, or appears to be, in
conflict with any other applicable provision, or in the event that this
Agreement permits any determination by the Owner Trustee or is silent or is
incomplete as to the course of action that the Owner Trustee is required to take
with respect to a particular set of facts, the Owner Trustee may give notice (in
such form as shall be appropriate under the circumstances) to the Instructing
Party requesting instruction and, to the extent that the Owner Trustee acts or
refrains from acting in good faith in accordance with any such instruction
received, the Owner Trustee shall not be liable, on account of such action or
inaction, to any Person. If the Owner Trustee shall not have received
appropriate instruction within 10 days of such notice (or within such shorter
period of time as reasonably may be specified in such notice or may be necessary
under the circumstances) it may, but shall be under no duty to, take or refrain
from taking such action, not inconsistent with this Agreement or the Basic
Documents, as it shall deem to be in the best interests of the
Certificateholder, and shall have no liability to any Person for such action or
inaction.

          SECTION 5.4. No Duties Except as Specified in this Agreement or in
                       -----------------------------------------------------
Instructions.  The Owner Trustee shall not have any duty or obligation to
------------
manage, make any

                                       13
<PAGE>

payment with respect to, register, record, sell, dispose of, or otherwise deal
with the Owner Trust Estate, or to otherwise take or refrain from taking any
action under, or in connection with, any document contemplated hereby to which
the Owner Trustee is a party, except as expressly provided by the terms of this
Agreement or in any document or written instruction received by the Owner
Trustee pursuant to Section 5.3; and no implied duties or obligations shall be
read into this Agreement or any Basic Document against the Owner Trustee. The
Owner Trustee shall have no responsibility for filing any financing or
continuation statement in any public office at any time or to otherwise perfect
or maintain the perfection of any security interest or lien granted to it
hereunder or to prepare or file any Commission filing for the Trust or to record
this Agreement or any Basic Document. The Owner Trustee nevertheless agrees that
it will, at its own cost and expense, promptly take all action as may be
necessary to discharge any Liens on any part of the Owner Trust Estate that
result from actions by, or claims against, the Owner Trustee (solely in its
individual capacity) and that are not related to the ownership or the
administration of the Owner Trust Estate.

          SECTION 5.5. No Action Except under Specified Documents or
                       ---------------------------------------------
Instructions. The Owner Trustee shall not manage, control, use, sell, dispose
------------
of or otherwise deal with any part of the Owner Trust Estate except (i) in
accordance with the powers granted to and the authority conferred upon the Owner
Trustee pursuant to this Agreement, (ii) in accordance with the Basic Documents
and (iii) in accordance with any document or instruction delivered to the Owner
Trustee pursuant to Section 5.3.

          SECTION 5.6. Restrictions. The Owner Trustee shall not take any action
                       ------------
(a) that is inconsistent with the purposes of the Trust set forth in Section 2.3
or (b) that, to the actual knowledge of the Owner Trustee, would result in the
Trust's becoming taxable as a corporation for Federal income tax purposes. The
Certificateholder shall not direct the Owner Trustee to take action that would
violate the provisions of this Section.

                                  ARTICLE VI.

                         Concerning the Owner Trustee
                         ----------------------------

          SECTION 6.1. Acceptance of Trusts and Duties. The Owner Trustee
                       -------------------------------
accepts the trusts hereby created and agrees to perform its duties hereunder
with respect to such trusts but only upon the terms of this Agreement. The Owner
Trustee also agrees to disburse all moneys actually received by it constituting
part of the Owner Trust Estate upon the terms of the Basic Documents and this
Agreement. The Owner Trustee shall not be answerable or accountable hereunder or
under any Basic Document under any circumstances, except (i) for its own willful
misconduct, bad faith or negligence, (ii) in the case of the inaccuracy of any
representation or warranty contained in Section 6.3 expressly made by the Owner
Trustee, (iii) for liabilities arising from the failure of the Owner Trustee to
perform obligations expressly undertaken by it in the last sentence of Section
5.4 hereof, (iv) for any investments issued by the Owner Trustee or any branch
or affiliate thereof in its commercial capacity or (v) for taxes, fees or other
charges on, based on or measured by, any fees, commissions or compensation

taken or omitted to be taken by it in accordance with the instructions of the
Instructing Party, the Servicer or the Certificateholder;

federal or Delaware state law, governmental rule or regulation governing the
banking or trust powers of the Owner Trustee or any judgment or order binding on
it, or constitute any default under its charter documents or by-laws or any
indenture, mortgage, contract, agreement or instrument to which it is a party or

          SECTION 6.4. Reliance; Advice of Counsel.
                       ---------------------------

upon any signature, instrument, notice, resolution, request, consent, order,
certificate, report, opinion, bond or other document or paper believed by it to
be genuine and believed by it to be signed by the proper party or parties. The
Owner Trustee may accept a certified copy of a resolution of the board of
directors or other governing body of any corporate party as conclusive evidence
that such resolution has been duly adopted by such body and that the same is in
full force and effect. As to any fact or matter the method of the determination

purposes hereof rely on a certificate, signed by the president or any vice
president or by the treasurer, secretary or other authorized officers of the
relevant party, as to such fact or matter, and such certificate shall constitute
full protection to the Owner Trustee for any action taken or omitted to be taken
by it in good faith in reliance thereon.

          (b)  In the exercise or administration of the trusts hereunder and in
the performance of its duties and obligations under this Agreement or the Basic
Documents, the Owner Trustee (i) may act directly or through its agents or
attorneys pursuant to agreements entered into with any of them, and the Owner
Trustee shall not be liable for the conduct or misconduct of such agents or
attorneys if such agents or attorneys shall have been selected by the Owner
Trustee with reasonable care, and (ii) may consult with counsel, accountants and
other skilled persons to be selected with reasonable care and employed by it.

respect to the legality, validity and enforceability of any Receivable, or the
perfection and priority of any security interest created by any Receivable in

for or with respect to the sufficiency of the Owner Trust Estate or its ability

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

the Trust or the Owner Trustee is a party shall be made only from the income and
proceeds of the Owner Trust Estate and only to the extent that the Owner Trust
shall have received income or proceeds from the Owner Trust Estate to make such
payments in accordance with the terms hereof. Bankers Trust (Delaware), or any
successor thereto, in its individual capacity, shall not be liable for any
amounts payable under this Agreement or any of the Basic Documents to which the
Trust or the Owner Trustee is a party.

          SECTION 6.9. Doing Business in Other Jurisdictions. Notwithstanding
                       -------------------------------------
anything contained herein to the contrary, neither Bankers Trust (Delaware) or
any successor thereto, nor the Owner Trustee shall be required to take any
action in any jurisdiction other than in the State of Delaware if the taking of
such action will, even after the appointment of a co-trustee or separate trustee
in accordance with Section 9.5 hereof, (i) require the consent or

                                       17

approval or authorization or order of or the giving of notice to, or the

consummation of the transactions by Bankers Trust (Delaware) (or any successor
thereto) or the Owner Trustee, as the case may be, contemplated hereby.

Basic Documents, the Owner Trust Estate, the administration of the Owner Trust
Estate or the action or inaction of the Owner Trustee hereunder, except only
that the Depositor shall not be liable for or required to indemnify the Owner
Trustee from and against Expenses arising or resulting from any of the matters
described in the third sentence of Section 6.1. The indemnities contained in
this Section and the rights under Section 7.1 shall survive the resignation or
termination of the Owner Trustee or the termination of this Agreement. In any

                                 ARTICLE VIII.

                        Termination of Trust Agreement

          SECTION 8.1. Termination of Trust Agreement.
                       ------------------------------

          (a)  This Agreement and the Trust shall terminate in accordance with
Section 3808 of the Business Trust Statute and be of no further force or effect
upon the latest of (i) the maturity or other liquidation of the last Receivable
(including the purchase by the Servicer at its option or by the Seller at its
option of the corpus of the Trust as described in Section 10.1 of the Sale and
Servicing Agreement) and the subsequent distribution of amounts in respect of

Certificateholder of all amounts required to be paid to it pursuant to this
Agreement and the payment to the Security Insurer of all amounts payable or
reimbursable to it pursuant to the Sale and Servicing Agreement; provided,
                                                                 --------
however, that the rights to indemnification under Section 7.2 and the rights
-------
under Section 7.1 shall survive the termination of the Trust. The Seller or the
Servicer shall promptly notify the Owner Trustee and the Security Insurer of any
prospective termination pursuant to this Section. The bankruptcy, liquidation,
dissolution, death or incapacity of the Certificateholder, shall not (x) operate
to terminate this Agreement or the Trust, nor (y) entitle the
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of all
or any part of the Trust or Owner Trust Estate nor (z) otherwise affect the
rights, obligations and liabilities of the parties hereto.

to revoke or terminate the Trust.

          (c)  Notice of any termination of the Trust, specifying the
Distribution Date upon which the Certificateholder shall surrender the
Certificate to the Trust Collateral Agent for payment of the final distribution
and cancellation, shall be given by the Owner Trustee by letter to the
Certificateholder mailed within five Business Days of receipt of notice of such
termination from the Servicer given pursuant to Section 10.1(c) of the Sale and
Servicing Agreement, stating (i) the Distribution Date upon or with respect to
which final payment of the Certificate shall be made upon presentation and
surrender of the Certificate at the office of the Trust Collateral Agent therein
designated, (ii) the amount of any such final payment, (iii) that the Record
Date otherwise applicable to such Distribution Date is not applicable, payments
being made only upon presentation and surrender of the Certificate at the office
of the Trust Collateral Agent therein specified and (iv) interest will cease to
accrue on the Certificate. The Owner Trustee shall give such notice to the Trust
Collateral Agent at the time such notice is given to the Certificateholder. Upon
presentation and surrender of the Certificate, the Trust Collateral Agent shall
cause to be distributed to the Certificateholder amounts distributable on such
Distribution Date pursuant to Section 5.7 of the Sale and Servicing Agreement.

                                       19
<PAGE>

          In the event that the Certificateholder shall not surrender the
Certificate for cancellation within six months after the date specified in the
above mentioned written notice, the Owner Trustee shall give a second written
notice to the Certificateholder to surrender the Certificate for cancellation
and receive the final distribution with respect thereto. If within one year
after the second notice all the Certificate shall not have been surrendered for
cancellation, the Owner Trustee may take appropriate steps, or may appoint an
agent to take appropriate steps, to contact the Certificateholder concerning
surrender of its Certificate, and the cost thereof shall be paid out of the
funds and other assets that shall remain subject to this Agreement. Any funds
remaining in the Trust after exhaustion of such remedies shall be distributed,
subject to applicable escheat laws, by the Owner Trustee to the Holder.

          (d)  Upon the completion of the winding up of the Trust in accordance
with Section 3808 of the Business Trust Statute and its termination, the Owner
Trustee shall cause the Certificate of Trust to be canceled by filing a
certificate of cancellation with the Secretary of State in accordance with the
provisions of Section 3810 of the Business Trust Statute.

            Successor Owner Trustees and Additional Owner Trustees
            ------------------------------------------------------

          SECTION 9.1. Eligibility Requirements for Owner Trustee. The Owner
                       ------------------------------------------
Trustee shall at all times be a corporation (i) satisfying the provisions of
Section 3807(a) of the Business Trust Statute; (ii) authorized to exercise
corporate trust powers; (iii) having a combined capital and surplus of at least
$50,000,000 and subject to supervision or examination by Federal or State
authorities; and (iv) acceptable to the Security Insurer in its sole discretion,
so long as an Insurer Default shall not have occurred and be continuing. If such
corporation shall publish reports of condition at least annually, pursuant to
law or to the requirements of the aforesaid supervising or examining authority,
then for the purpose of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. In case at any time the
Owner Trustee shall cease to be eligible in accordance with the provisions of
this Section, the Owner Trustee shall resign immediately in the manner and with
the effect specified in Section 9.2.

          SECTION 9.2. Resignation or Removal of Owner Trustee. The Owner
                       ---------------------------------------
Trustee may at any time resign and be discharged from the trusts hereby created
by giving written notice thereof to the Depositor, the Security Insurer and the
Servicer. Upon receiving such notice of resignation, the Depositor shall
promptly appoint a successor Owner Trustee by written instrument, in duplicate,
one copy of which instrument shall be delivered to the resigning Owner Trustee
and one copy to the successor Owner Trustee, provided that the Depositor shall
have received written confirmation from each of the Rating Agencies that the
proposed appointment will not result in an increased capital charge to the
Security Insurer by either of the Rating Agencies. If no successor Owner Trustee
shall have been so appointed and have accepted appointment within 30 days after
the giving of such notice of resignation, the resigning Owner Trustee or the
Security Insurer may petition any court of competent jurisdiction for the
appointment of a successor Owner Trustee.

                                       20
<PAGE>

          If at any time the Owner Trustee shall cease to be eligible in
accordance with the provisions of Section 9.1 and shall fail to resign after
written request therefor by the Depositor, or if at any time the Owner Trustee
shall be legally unable to act, or shall be adjudged bankrupt or insolvent, or a
receiver of the Owner Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Owner Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Depositor with the consent of the Security Insurer (so
long as an Insurer Default shall not have occurred and be continuing) may remove
the Owner Trustee.  If the Depositor shall remove the Owner Trustee under the
authority of the immediately preceding sentence, the Depositor shall promptly
appoint a successor Owner Trustee by written instrument, in duplicate, one copy
of which instrument shall be delivered to the outgoing Owner Trustee so removed,
one copy to the Security Insurer and one copy to the successor Owner Trustee and
payment of all fees owed to the outgoing Owner Trustee.

          Any resignation or removal of the Owner Trustee and appointment of a
successor Owner Trustee pursuant to any of the provisions of this Section shall
not become effective until acceptance of appointment by the successor Owner
Trustee pursuant to Section 9.3 and payment of all fees and expenses owed to the
outgoing Owner Trustee.  The Depositor shall provide notice of such resignation
or removal of the Owner Trustee to each of the Rating Agencies.

          SECTION 9.3. Successor Owner Trustee. Any successor Owner Trustee
                       -----------------------
appointed pursuant to Section 9.2 shall execute, acknowledge and deliver to the
Depositor, the Servicer, the Security Insurer and to its predecessor Owner
Trustee an instrument accepting such appointment under this Agreement, and
thereupon the resignation or removal of the predecessor Owner Trustee shall
become effective and such successor Owner Trustee, without any further act, deed
or conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor under this Agreement, with like effect as if
originally named as Owner Trustee. The predecessor Owner Trustee shall upon
payment of its fees and expenses deliver to the successor Owner Trustee all
documents and statements and monies held by it under this Agreement; and the
Depositor and the predecessor Owner Trustee shall execute and deliver such
instruments and do such other things as may reasonably be required for fully and
certainly vesting and confirming in the successor Owner Trustee all such rights,
powers, duties and obligations.

          No successor Owner Trustee shall accept appointment as provided in
this Section unless at the time of such acceptance such successor Owner Trustee
shall be eligible pursuant to Section 9.1.

          Upon acceptance of appointment by a successor Owner Trustee pursuant
to this Section, the Servicer shall mail notice of the successor of such Owner
Trustee to the Certificateholder, the Trustee, the Noteholders and the Rating
Agencies.  If the Servicer shall fail to mail such notice within 10 days after
acceptance of appointment by the successor Owner Trustee, the successor Owner
Trustee shall cause such notice to be mailed at the expense of the Servicer.

          SECTION 9.4. Merger or Consolidation of Owner Trustee. Any corporation
                       ----------------------------------------
into which the Owner Trustee may be merged or converted or with which it may be
consolidated,

                                       21
<PAGE>

or any corporation resulting from any merger, conversion or consolidation to
which the Owner Trustee shall be a party, or any corporation succeeding to all
or substantially all of the corporate trust business of the Owner Trustee, shall
be the successor of the Owner Trustee hereunder, provided such corporation shall
be eligible pursuant to Section 9.1, without the execution or filing of any
instrument or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding; provided further that the Owner Trustee
shall mail notice of such merger or consolidation to the Rating Agencies.

          SECTION 9.5. Appointment of Co-Trustee or Separate Trustee.
                       ---------------------------------------------
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Owner Trust Estate or any Financed Vehicle may at the time be located,
the Servicer and the Owner Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Owner Trustee and the Security Insurer to act as co-trustee, jointly with
the Owner Trustee, or separate trustee or separate trustees, of all or any part
of the Owner Trust Estate, and to vest in such Person, in such capacity, such
title to the Trust, or any part thereof, and, subject to the other provisions of
this Section, such powers, duties, obligations, rights and trusts as the
Servicer and the Owner Trustee may consider necessary or desirable. If the
Servicer shall not have joined in such appointment within 15 days after the
receipt by it of a request so to do, the Owner Trustee subject, unless an
Insurer Default shall have occurred and be continuing, to the approval of the
Security Insurer (which approval shall not be unreasonably withheld) shall have
the power to make such appointment. No co-trustee or separate trustee under this
Agreement shall be required to meet the terms of eligibility as a successor
trustee pursuant to Section 9.1 and no notice of the appointment of any co-
trustee or separate trustee shall be required pursuant to Section 9.3.

          Each separate trustee and co-trustee shall, to the extent permitted by
law, be appointed and act subject to the following provisions and conditions:

               (i)   all rights, powers, duties and obligations conferred or
     imposed upon the Owner Trustee shall be conferred upon and exercised or
     performed by the Owner Trustee and such separate trustee or co-trustee
     jointly (it being understood that such separate trustee or co-trustee is
     not authorized to act separately without the Owner Trustee joining in such
     act), except to the extent that under any law of any jurisdiction in which
     any particular act or acts are to be performed, the Owner Trustee shall be
     incompetent or unqualified to perform such act or acts, in which event such
     rights, powers, duties and obligations (including the holding of title to
     the Trust or any portion thereof in any such jurisdiction) shall be
     exercised and performed singly by such separate trustee or co-trustee, but
     solely at the direction of the Owner Trustee;

               (ii)  no trustee under this Agreement shall be personally liable
     by reason of any act or omission of any other trustee under this Agreement;
     and

               (iii) the Servicer and the Owner Trustee acting jointly may at
     any time accept the resignation of or remove any separate trustee or co-
     trustee.

                                       22
<PAGE>

          Any notice, request or other writing given to the Owner Trustee shall
be deemed to have been given to each of the then separate trustees and co-
trustees, as effectively as if given to each of them.  Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement and
the conditions of this Article.  Each separate trustee and co-trustee, upon its
acceptance of the trusts conferred, shall be vested with the estates or property
specified in its instrument of appointment, either jointly with the Owner
Trustee or separately, as may be provided therein, subject to all the provisions
of this Agreement, specifically including every provision of this Agreement
relating to the conduct of, affecting the liability of, or affording protection
to, the Owner Trustee.  Each such instrument shall be filed with the Owner
Trustee and a copy thereof given to the Servicer and the Security Insurer.

          Any separate trustee or co-trustee may at any time appoint the Owner
Trustee, its agent or attorney-in-fact with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name.  If any separate trustee or co-trustee
shall die, become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Owner Trustee, to the extent permitted by law, without the appointment of a new
or successor trustee.

          (b)  This Agreement may also be amended from time to time, with the
prior written consent of the Security Insurer (so long as an Insurer Default

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 any other consents of the Certificateholder provided for in this

     This is the duly authorized Certificate designated as "Asset Backed

Certificate will be made after due notice by the Owner Trustee of the pendency
of such distribution and only upon presentation and surrender of this
Certificate at the office or agency maintained for the purpose by the Owner
Trustee in the Borough of Manhattan, The City of New York.

forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

                           (Reverse of Certificate)

     The Certificate does not represent an obligation of, or an interest in, the
Seller, the Servicer, the Owner Trustee or any Affiliates of any of them and no
recourse may be had against such parties or their assets, except as may be
expressly set forth or contemplated herein or in the Trust Agreement, the
Indenture or the Basic Documents.  In addition, this Certificate is not
guaranteed by any governmental agency or instrumentality and is limited in right
of payment to certain collections with respect to the Receivables, all as more
specifically set forth herein and in the Sale and Servicing Agreement.  A copy
of each of the Sale and Servicing Agreement and the Trust Agreement may be
examined during normal business hours at the principal office of the Seller, and
at such other places, if any, designated by the Seller, by any Certificateholder
upon written request.

     The Trust Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Seller under the Trust Agreement at any time by the Seller and the Owner Trustee
with the consent of the Note Majority and the Certificateholder.  Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and on all future Holders of this Certificate and of any Certificate
issued upon the transfer hereof or in exchange hereof or in lieu hereof whether
or not notation of such consent is made upon this Certificate.  The Trust
Agreement also permits the amendment thereof, in certain limited circumstances,
without the consent of the Certificateholder.

     As provided in the Trust Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registerable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies of the Certificate Registrar maintained by
the Owner Trustee in the Borough of Manhattan, The City of New York, accompanied
by a written instrument of transfer in form satisfactory to the Owner Trustee
and the Certificate Registrar duly executed by the holder hereof or such
holder's attorney duly authorized in writing, and thereupon a new Certificate
evidencing the same aggregate interest in the Trust will be issued to the
designated transferee.  The initial Certificate Registrar appointed under the
Trust Agreement is Bankers Trust Company.  No service charge will be made for
any such registration of transfer or exchange, but the Owner Trustee or the
Certificate Registrar may require payment of a sum sufficient to cover any tax
or governmental charge payable in connection therewith.

     The Owner Trustee, the Security Insurer and any agent of the Owner Trustee
or the Security Insurer may treat the person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Owner Trustee,
the Security Insurer nor any such agent shall be affected by any notice to the
contrary.

     The obligations and responsibilities created by the Trust Agreement and the
Trust created thereby shall terminate upon the payment to the Certificateholder
of all amounts required to be paid to it pursuant to the Trust Agreement and the
Sale and Servicing Agreement and the disposition of all property held as part of
the Trust.  The Seller or the Servicer of the Receivables may at its option
purchase the corpus of the Trust at a price specified in the Sale and Servicing
Agreement, and such purchase of the Receivables and other property of the Trust
will effect

                                      A-5

early retirement of the Certificate; however, such right of purchase is
exercisable, subject to certain restrictions, only as of the last day of any
Collection Period as of which the Pool Balance is 10% or less of the Original
Pool Balance.

     The Certificate may not be acquired by (a) an employee benefit plan (as
defined in Section 3(3) of ERISA) that is subject to the provisions of Title I
of ERISA, (b) a plan (as defined in Section 4975(e)(1) of the Code) that is
subject to subject to Section 4975 or (c) any entity whose underlying assets
include assets of a plan described in (a) or (b) above by reason of such plan's
investment in the entity (each, a "Benefit Plan").  By accepting and holding
this Certificate, the Holder hereof shall be deemed to have represented and
warranted that it is not a Benefit Plan.

     The recitals contained herein shall be taken as the statements of the
Depositor or the Servicer, as the case may be, and the Owner Trustee assumes no
responsibility for the correctness thereof.  The Owner Trustee makes no
representations as to the validity or sufficiency of this Certificate or of any
Receivable or related document.

Unless the certificate of authentication hereon shall have been executed by an
authorized officer of the Owner Trustee, by manual or facsimile signature, this
Certificate shall not entitle the Holder hereof to any benefit under the Trust
Agreement or the Sale and Servicing Agreement or be valid for any purpose.

     SECTION 2.3. Further Encumbrance of Trust Property.
                  -------------------------------------

     (a) Immediately upon the conveyance to the Trust by the Seller of any item
of the Trust Property pursuant to Section 2.1, all right, title and interest of
the Seller in and to such item of Trust Property shall terminate, and all such
right, title and interest shall vest in the Trust, in accordance with the Trust
Agreement and Sections 3802 and 3805 of the Business Trust Statute (as defined
in the Trust Agreement).

     (b) Immediately upon the vesting of the Trust Property in the Trust, the
Trust shall have the sole right to pledge or otherwise encumber, such Trust
Property. Pursuant to the Indenture, the Trust shall grant a security interest
in the Trust Property to the Trust Collateral Agent securing the repayment of
the Notes. The Certificates shall represent the beneficial ownership interest in
the Trust Property, and the Certificateholders shall be entitled to receive
distributions with respect thereto as set forth herein.

     (c) Following the payment in full of the Notes and the release and
discharge of the Indenture, all covenants of the Issuer under Article III of the
Indenture shall, until payment in full of the Certificates, remain as covenants
of the Issuer for the benefit of the Certificateholders, enforceable by the
Certificateholders to the same extent as such covenants were enforceable by the
Noteholders prior to the discharge of the Indenture. Any rights of the Trustee
under Article III of the Indenture, following the discharge of the Indenture,
shall vest in Certificateholders.

                                       26
<PAGE>

     (d) The Trust Collateral Agent shall, at such time as there are no
Securities outstanding and all sums due to (i) the Trustee pursuant to the
Indenture and (ii) the Trust Collateral Agent pursuant to this Agreement, have
been paid, release any remaining portion of the Trust Property to the Seller.

                                  ARTICLE III

                                The Receivables
                                ---------------

     SECTION 3.1. Representations and Warranties of Seller. The Seller hereby
                  ----------------------------------------
represents and warrants that each of the representations and warranties set
forth on the Schedule of Representations attached hereto as Schedule B is true
and correct on which the Issuer is deemed to have relied in acquiring the
Receivables and upon which the Insurer shall be deemed to rely in issuing the
Note Policy. Such representations and warranties speak as of the execution and
delivery of this Agreement and as of the Closing Date in the case of the Initial
Receivables, and as of the related Subsequent Transfer Date in case of the
Subsequent Receivables, but shall survive the sale, transfer and assignment of
the Receivables to the Issuer and the pledge thereof to the Trustee pursuant to
the Indenture.

     SECTION 3.2. Repurchase upon Breach.
                  ----------------------

     (a) The Seller, the Servicer, the Insurer, the Trust Collateral Agent or
the Owner Trustee, as the case may be, shall inform the other parties to this
Agreement promptly, notice in writing, upon the discovery of any breach of the
Seller's representations and warranties made pursuant to Section 3.1. As of the
last day of the second (or, if the Seller so elects, the first) month following
the discovery by the Seller or receipt by the Seller of notice of such breach,
unless such breach is cured by such date, the Seller shall have an obligation to
repurchase any Receivable in which the interests of the Noteholders or the
Insurer are materially and adversely affected by any such breach as of such
date. The "second month" shall mean the month following the month in which
discovery occurs or notice is given, and the "first month" shall mean the month
in which discovery occurs or notice is given. In consideration of and
simultaneously with the repurchase of the Receivable, the Seller shall remit, or
cause AmeriCredit to remit, to the Collection Account the Purchase Amount in the
manner specified in Section 5.6 and the Issuer shall execute such assignments
and other documents reasonably requested by such person in order to effect such
repurchase. The sole remedy of the Issuer, the Owner Trustee, the Trust
Collateral Agent, the Trustee or the Noteholders with respect to a breach of
representations and warranties pursuant to Section 3.1 and the agreement
contained in this Section shall be the repurchase of Receivables pursuant to
this Section, subject to the conditions contained herein or to enforce the
obligation of AmeriCredit to the Seller to repurchase such Receivables pursuant
to the Purchase Agreement. Neither the Owner Trustee, the Trust Collateral Agent
nor the Trustee shall have a duty to conduct any affirmative investigation as to
the occurrence of any conditions requiring the repurchase of any Receivable
pursuant to this Section.

     In addition to the foregoing and notwithstanding whether the related
Receivable shall have been purchased by the Seller, the Seller shall indemnify
the Trust, the Trustee, the Backup

                                       27
<PAGE>

Servicer, the Trust Collateral Agent, Collateral Agent and the officers,
directors, agents and employees thereof, the Insurer, and the Noteholders
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 breach.

     (b) Pursuant to Section 2.1 of this Agreement, the Seller conveyed to the
Trust all of the Seller's right, title and interest in its rights and benefits,
but none of its obligations or burdens, under the Purchase Agreement including
the Seller's rights under the Purchase Agreement and the delivery requirements,
representations and warranties and the cure or repurchase obligations of
AmeriCredit and CP Funding thereunder. The Seller hereby represents and warrants
to the Trust that such assignment is valid, enforceable and effective to permit
the Trust to enforce such obligations of AmeriCredit and CP Funding under the
Purchase Agreement.

     SECTION 3.3. Custody of Receivables Files.
                  ----------------------------

     (a)  In connection with the sale, transfer and assignment of the
Receivables and the Other Conveyed Property to the Trust pursuant to this
Agreement and simultaneously with the execution and delivery of this Agreement,
the Trust Collateral Agent shall enter into the Custodian Agreement with the
Custodian, dated as of May 22, 2000, pursuant to which the Trust Collateral
Agent shall revocably appoint the Custodian, and the Custodian shall accept such
appointment, to act as the agent of the Trust Collateral Agent as custodian of
the following documents or instruments in its possession which shall be
delivered to the Custodian as agent of the Trust Collateral Agent on or before
the Closing Date (with respect to each Receivable):

          (i)   The fully executed original of the Receivable (together with any
     agreements modifying the Receivable, including without limitation any
     extension agreements);

          (ii)  The original credit application, or a copy thereof, of each
     Obligor, fully executed by each such Obligor on AmeriCredit's customary
     form, or on a form approved by AmeriCredit, for such application; and

          (iii) The original certificate of title (when received) and otherwise
     such documents, if any, that AmeriCredit keeps on file in accordance with
     its customary procedures indicating that the Financed Vehicle is owned by
     the Obligor and subject to the interest of AmeriCredit as first lienholder
     or secured party (including any Lien Certificate received by AmeriCredit),
     or, if such original certificate of title has not yet been received, a copy
     of the application therefor, showing AmeriCredit as secured party.

     The Trust Collateral Agent may act as the Custodian, in which case the
Trust Collateral Agent shall be deemed to have assumed the obligations of the
Custodian specified in the Custodian Agreement.

     (b)  Upon payment in full of any Receivable, the Servicer will notify the
Custodian pursuant to a certificate of an officer of the Servicer (which
certificate shall include a statement to the effect that all amounts received in
connection with such payments which are required to be deposited in the
Collection Account pursuant to Section 4.1 have been so deposited) and shall
request delivery of the Receivable and Receivable File to the Servicer. From
time to time as

                                       28
<PAGE>

appropriate for servicing and enforcing any Receivable, the Custodian shall,
upon written request of an officer of the Servicer and delivery to the Custodian
of a receipt signed by such officer, cause the original Receivable and the
related Receivable File to be released to the Servicer. The Servicer's receipt
of a Receivable and/or Receivable File shall obligate the Servicer to return the
original Receivable and the related Receivable File to the Custodian when its
need by the Servicer has ceased unless the Receivable is repurchased as
described in Section 3.2 or 4.7.

                                  ARTICLE IV

                  Administration and Servicing of Receivables
                  -------------------------------------------

     SECTION 4.1. Duties of the Servicer. The Servicer is hereby authorized to
                  ----------------------
act as agent for the Trust and in such capacity shall manage, service,
administer and make collections on the Receivables, and perform the other
actions required by the Servicer under this Agreement. The Servicer agrees that
its servicing of the Receivables shall be carried out in accordance with
customary and usual procedures of institutions which service motor vehicle
retail installment sales contracts and, to the extent more exacting, the degree
of skill and attention that the Servicer exercises from time to time with
respect to all comparable motor vehicle receivables that it services for itself
or others. In performing such duties, so long as AmeriCredit is the Servicer, it
shall substantially comply with the policies and procedures described on
Schedule C, as such policies and procedures may be updated from time to time.
The Servicer's duties shall include, without limitation, collection and posting
of all payments, responding to inquiries of Obligors on the Receivables,
investigating delinquencies, sending payment coupons to Obligors, reporting any
required tax information to Obligors, monitoring the collateral, complying with
the terms of the Lockbox Agreement, accounting for collections and furnishing
monthly and annual statements to the Trust Collateral Agent, the Trustee and the
Insurer with respect to distributions, monitoring the status of Insurance
Policies with respect to the Financed Vehicles and performing the other duties
specified herein.

     The Servicer shall also administer and enforce all rights and
responsibilities of the holder of the Receivables provided for in the Dealer
Agreements (and shall maintain possession of the Dealer Agreements, to the
extent it is necessary to do so), the Dealer Assignments and the Insurance
Policies, to the extent that such Dealer Agreements, Dealer Assignments and
Insurance Policies relate to the Receivables, the Financed Vehicles or the
Obligors.  To the extent consistent with the standards, policies and procedures
otherwise required hereby, the Servicer shall follow its customary standards,
policies, and procedures and shall have full power and authority, acting alone,
to do any and all things in connection with such managing, servicing,
administration and collection that it may deem necessary or desirable.  Without
limiting the generality of the foregoing, the Servicer is hereby authorized and
empowered by the Trust to execute and deliver, on behalf of the Trust, any and
all instruments of satisfaction or cancellation, or of partial or full release
or discharge, and all other comparable instruments, with respect to the
Receivables and with respect to the Financed Vehicles; provided, however, that
notwithstanding the foregoing, the Servicer shall not, except pursuant to an
order from a court of competent jurisdiction, release an Obligor from payment of
any unpaid amount under any Receivable or waive the right to collect the unpaid
balance of any Receivable from the Obligor.

                                       29
<PAGE>

     The Servicer is hereby authorized to commence, in it's own name or in the
name of the Trust, a legal proceeding to enforce a Receivable pursuant to
Section 4.3 or to commence or participate in any other legal proceeding
(including, without limitation, a bankruptcy proceeding) relating to or
involving a Receivable, an Obligor or a Financed Vehicle.  If the Servicer
commences or participates in such a legal proceeding in its own name, the Trust
shall thereupon be deemed to have automatically assigned such Receivable to the
Servicer solely for purposes of commencing or participating in any such
proceeding as a party or claimant, and the Servicer is authorized and empowered
by the Trust to execute and deliver in the Servicer's name any notices, demands,
claims, complaints, responses, affidavits or other documents or instruments in
connection with any such proceeding.  The Trust Collateral Agent and the Owner
Trustee shall furnish the Servicer with any limited powers of attorney and other
documents which the Servicer may reasonably request and which the Servicer deems
necessary or appropriate and take any other steps which the Servicer may deem
necessary or appropriate to enable the Servicer to carry out its servicing and
administrative duties under this Agreement.

     SECTION 4.2. Collection of Receivable Payments; Modifications of
                  ---------------------------------------------------
Receivables; Lockbox Agreements.
-------------------------------

     (a) Consistent with the standards, policies and procedures required by this
Agreement, the Servicer shall make reasonable efforts to collect all payments
called for under the terms and provisions of the Receivables as and when the
same shall become due, and shall follow such collection procedures as it follows
with respect to all comparable automobile receivables that it services for
itself or others and otherwise act with respect to the Receivables, the Dealer
Agreements, the Dealer Assignments, the Insurance Policies and the Other
Conveyed Property in such manner as will, in the reasonable judgment of the
Servicer, maximize the amount to be received by the Trust with respect thereto.
The Servicer is authorized in its discretion to waive any prepayment charge,
late payment charge or any other similar fees that may be collected in the
ordinary course of servicing any Receivable.

     (b) The Servicer may at any time agree to a modification or amendment of a
Receivable in order to (i) change the Obligor's regular due date to a date
within the Collection Period in which such due date occurs or (ii) re-amortize
the Scheduled Receivables Payments on the Receivable following a partial
prepayment of principal, in accordance with its customary procedures if the
Servicer believes in good faith that such extension, modification or amendment
is necessary to avoid a default on such Receivable, will maximize the amount to
be received by the Trust with respect to such Receivable, and is otherwise in
the best interests of the Trust.

     (c) The Servicer may grant payment extensions on, or other modifications or
amendments to, a receivable (in addition to those modifications permitted by
Section 4.2(b)) in accordance with its customary procedures if the Servicer
believes in good faith that such extension, modification or amendment is
necessary to avoid a default on such Receivable, will maximize the amount to be
received by the Trust with respect to such Receivable, and is otherwise in the
best interests of the Trust; provided, however, that:

         (i) The aggregate period of all extensions on a Receivable shall not
     exceed six months;

                                       30
<PAGE>

          (ii)   In no event may a Receivable be extended beyond the Collection
     Period immediately preceding the latest Final Scheduled Distribution Date;

          (iii)  The average Monthly Extension Rate for any three consecutive
     calendar months shall not exceed 4%; and

          (iv)   So long as an Insurer Default shall not have occurred and be
     continuing, the Servicer shall not amend or modify a Receivable (except as
     provided in Section 4.2(b) and this Section 4.2(c)) without the consent of
     the Insurer or a Note Majority (if an Insurer Default shall have occurred
     and be continuing).

     With respect to clause (iii) of this Section 4.2(c), in the event the
average of the Monthly Extension Rates calculated with respect to three
consecutive calendar months exceeds 4% (which information shall be set forth in
the related Servicer's Certificate), the Servicer shall, on the third such
Accounting Date, purchase from the Trust the Receivables with respect to which
payment had been extended (starting with the Receivables most recently so
extended) in an aggregate Principal Balance equal to the product of (i) the
difference between such average of Monthly Extension Rates and 4% and (ii) the
Aggregate Principal Balance, and pay the related Purchase Amount on the related
Preliminary Determination Date; provided, however, that in the event the Backup
                                --------  -------
Servicer shall be acting as Servicer hereunder, the foregoing sentence shall
apply only in respect of Receivables as to which payments had been extended by
such Backup Servicer.

     (d)  The Servicer shall use its best efforts to notify or direct Obligors
to make all payments on the Receivables, whether by check or by direct debit of
the Obligor's bank account, to be made directly to one or more Lockbox Banks,
acting as agent for the Trust pursuant to a Lockbox Agreement. The Servicer
shall use its best efforts to notify or direct any Lockbox Bank to deposit all
payments on the Receivables in the Lockbox Account no later than the Business
Day after receipt, and to cause all amounts credited to the Lockbox Account on
account of such payments to be transferred to the Collection Account no later
than the second Business Day after receipt of such payments. The Lockbox Account
shall be a demand deposit account held by the Lockbox Bank, or at the request of
the Controlling Party, an Eligible Account.

     Prior to the Closing Date, the Servicer shall have notified each Obligor
that makes its payments on the Receivables by check to make such payments
thereafter directly to the Lockbox Bank (except in the case of Obligors that
have already been making such payments to the Lockbox Bank), and shall have
provided each such Obligor with remittance invoices in order to enable such
Obligors to make such payments directly to the Lockbox Bank for deposit into the
Lockbox Account, and the Servicer will continue, not less often than every three
months, to so notify those Obligors who have failed to make payments to the
Lockbox Bank.  If and to the extent requested by the Controlling Party, the
Servicer shall request each Obligor that makes payment on the Receivables by
direct debit of such Obligor's bank account, to execute a new authorization for
automatic payment which in the judgment of the Controlling Party is sufficient
to authorize direct debit by the Lockbox Bank on behalf of the Trust.  If at any
time, the Lockbox Bank is unable to directly debit an Obligor's bank account
that makes payment on the Receivables by direct debit and if such inability is
not cured within 15 days or cannot be cured by execution by the Obligor of a new
authorization for automatic payment, the Servicer shall

                                       31
<PAGE>

notify such Obligor that it cannot make payment by direct debit and must
thereafter make payment by check.

     Notwithstanding any Lockbox Agreement, or any of the provisions of this
Agreement relating to the Lockbox Agreement, the Servicer shall remain obligated
and liable to the Trust, the Trust Collateral Agent and Noteholders for
servicing and administering the Receivables and the Other Conveyed Property in
accordance with the provisions of this Agreement without diminution of such
obligation or liability by virtue thereof, provided, however, that the foregoing
shall not apply to any Backup Servicer for so long as a Lockbox Bank is
performing its obligations pursuant to the terms of a Lockbox Agreement.

     In the event of a termination of the Servicer, the successor Servicer shall
assume all of the rights and obligations of the outgoing Servicer under the
Lockbox Agreement subject to the terms hereof.  In such event, the successor
Servicer shall be deemed to have assumed all of the outgoing Servicer's interest
therein and to have replaced the outgoing Servicer as a party to each such
Lockbox Agreement to the same extent as if such Lockbox Agreement had been
assigned to the successor Servicer, except that the outgoing Servicer shall not
thereby be relieved of any liability or obligations on the part of the outgoing
Servicer to the Lockbox Bank under such Lockbox Agreement.  The outgoing
Servicer shall, upon request of the Trust Collateral Agent, but at the expense
of the outgoing Servicer, deliver to the successor Servicer all documents and
records relating to each such Lockbox Agreement and an accounting of amounts
collected and held by the Lockbox Bank and otherwise use its best efforts to
effect the orderly and efficient transfer of any Lockbox Agreement to the
successor Servicer.  In the event that the Insurer (so long as an Insurer
Default shall not have occurred and be continuing) or a Note Majority (if an
Insurer Default shall have occurred and be continuing) elects to change the
identity of the Lockbox Bank, the outgoing Servicer, at its expense, shall cause
the Lockbox Bank to deliver, at the direction of the Insurer (so long as an
Insurer Default shall not have occurred and be continuing) or a Note Majority
(if an Insurer Default shall have occurred and be continuing) to the Trust
Collateral Agent or a successor Lockbox Bank, all documents and records relating
to the Receivables and all amounts held (or thereafter received) by the Lockbox
Bank (together with an accounting of such amounts) and shall otherwise use its
best efforts to effect the orderly and efficient transfer of the lockbox
arrangements and the Servicer shall notify the Obligors to make payments to the
Lockbox established by the successor.

     (e)  The Servicer shall remit all payments by or on behalf of the Obligors
received directly by the Servicer to the Lockbox Bank for deposit into the
Collection Account, in either case, without deposit into any intervening account
and as soon as practicable, but in no event later than the Business Day after
receipt thereof.

     SECTION 4.3.   Realization upon Receivables.
                    -----------------------------

     (a)  Consistent with the standards, policies and procedures required by
this Agreement, the Servicer shall use its best efforts to repossess (or
otherwise comparably convert the ownership of) and liquidate any Financed
Vehicle securing a Receivable with respect to which the Servicer has determined
that payments thereunder are not likely to be resumed, as soon as is practicable
after default on such Receivable but in no event later than the date on which
all or any portion of a Scheduled Receivables Payment has become 91 days
delinquent; provided,
            --------

                                       32
<PAGE>

however, that the Servicer may elect not to repossess a Financed Vehicle within
-------
such time period if in its good faith judgment it determines that the proceeds
ultimately recoverable with respect to such Receivable would be increased by
forbearance. The Servicer is authorized to follow such customary practices and
procedures as it shall deem necessary or advisable, consistent with the standard
of care required by Section 4.1, which practices and procedures may include
reasonable efforts to realize upon any recourse to Dealers, the sale of the
related Financed Vehicle at public or private sale, the submission of claims
under an Insurance Policy and other actions by the Servicer in order to realize
upon such a Receivable. The foregoing is subject to the provision that, in any
case in which the Financed Vehicle shall have suffered damage, the Servicer
shall not expend funds in connection with any repair or towards the repossession
of such Financed Vehicle unless it shall determine in its discretion that such
repair and/or repossession shall increase the proceeds of liquidation of the
related Receivable by an amount greater than the amount of such expenses. All
amounts received upon liquidation of a Financed Vehicle shall be remitted
directly by the Servicer to the Collection Account without deposit into any
intervening account as soon as practicable, but in no event later than the
Business Day after receipt thereof. The Servicer shall be entitled to recover
all reasonable expenses incurred by it in the course of repossessing and
liquidating a Financed Vehicle into cash proceeds, but only out of the cash
proceeds of such Financed Vehicle, any deficiency obtained from the Obligor or
any amounts received from the related Dealer, which amounts in reimbursement may
be retained by the Servicer (and shall not be required to be deposited as
provided in Section 4.2(e)) to the extent of such expenses. The Servicer shall
pay on behalf of the Trust any personal property taxes assessed on repossessed
Financed Vehicles. The Servicer shall be entitled to reimbursement of any such
tax from Net Liquidation Proceeds with respect to such Receivable.

     (b)  If the Servicer elects to commence a legal proceeding to enforce a
Dealer Agreement or Dealer Assignment, the act of commencement shall be deemed
to be an automatic assignment from the Trust to the Servicer of the rights under
such Dealer Agreement and Dealer Assignment for purposes of collection only. If,
however, in any enforcement suit or legal proceeding it is held that the
Servicer may not enforce a Dealer Agreement or Dealer Assignment on the grounds
that it is not a real party in interest or a Person entitled to enforce the
Dealer Agreement or Dealer Assignment, the Owner Trustee and/or the Trust
Collateral Agent, at the Servicer's expense, or the Seller, at the Seller's
expense, shall take such steps as the Servicer deems reasonably necessary to
enforce the Dealer Agreement or Dealer Assignment, including bringing suit in
its name or the name of the Seller or of the Trust and the Owner Trustee and/or
the Trust Collateral Agent for the benefit of the Noteholders. All amounts
recovered shall be remitted directly by the Servicer as provided in Section
4.2(e).

     SECTION 4.4.   Insurance.
                    ----------

     (a)  The Servicer shall require, in accordance with its customary servicing
policies and procedures, that each Financed Vehicle be insured by the related
Obligor under the Insurance Policies referred to in Paragraph 24 of the Schedule
of Representations and Warranties and shall monitor the status of such physical
loss and damage insurance coverage thereafter, in accordance with its customary
servicing procedures. Each Receivable requires the Obligor to maintain such
physical loss and damage insurance, naming AmeriCredit and its successors and
assigns as additional insureds, and permits the holder of such Receivable to
obtain physical loss and damage insurance at the expense of the Obligor if the
Obligor fails to maintain such insurance.

                                       33
<PAGE>

If the Servicer shall determine that an Obligor has failed to obtain or maintain
a physical loss and damage Insurance Policy covering the related Financed
Vehicle which satisfies the conditions set forth in clause (i)(a) of such
Paragraph 24 (including, without limitation, during the repossession of such
Financed Vehicle) the Servicer may enforce the rights of the holder of the
Receivable under the Receivable to require the Obligor to obtain such physical
loss and damage insurance in accordance with its customary servicing policies
and procedures. The Servicer may maintain a vendor's single interest or other
collateral protection insurance policy with respect to all Financed Vehicles
("Collateral Insurance") which policy shall by its terms insure against physical
loss and damage in the event any Obligor fails to maintain physical loss and
damage insurance with respect to the related Financed Vehicle. All policies of
Collateral Insurance shall be endorsed with clauses providing for loss payable
to the Servicer. Costs incurred by the Servicer in maintaining such Collateral
Insurance shall be paid by the Servicer.

     (b)  The Servicer may, if an Obligor fails to obtain or maintain a physical
loss and damage Insurance Policy, obtain insurance with respect to the related
Financed Vehicle and advance on behalf of such Obligor, as required under the
terms of the insurance policy, the premiums for such insurance (such insurance
being referred to herein as "Force-Placed Insurance"). All policies of Force-
Placed Insurance shall be endorsed with clauses providing for loss payable to
the Servicer. Any cost incurred by the Servicer in maintaining such Force-Placed
Insurance shall only be recoverable out of premiums paid by the Obligors or Net
Liquidation Proceeds with respect to the Receivable, as provided in Section
4.4(c).

     (c)  In connection with any Force-Placed Insurance obtained hereunder, the
Servicer may, in the manner and to the extent permitted by applicable law,
require the Obligors to repay the entire premium to the Servicer. In no event
shall the Servicer include the amount of the premium in the Amount Financed
under the Receivable. For all purposes of this Agreement, the Insurance Add-On
Amount with respect to any Receivable having Force-Placed Insurance will be
treated as a separate obligation of the Obligor and will not be added to the
Principal Balance of such Receivable, and amounts allocable thereto will not be
available for distribution on the Notes and the Certificates. The Servicer shall
retain and separately administer the right to receive payments from Obligors
with respect to Insurance Add-On Amounts or rebates of Forced-Placed Insurance
premiums. If an Obligor makes a payment with respect to a Receivable having
Force-Placed Insurance, but the Servicer is unable to determine whether the
payment is allocable to the Receivable or to the Insurance Add-On Amount, the
payment shall be applied first to any unpaid Scheduled Receivables Payments and
then to the Insurance Add-On Amount. Net Liquidation Proceeds on any Receivable
will be used first to pay the Principal Balance and accrued interest on such
Receivable and then to pay the related Insurance Add-On Amount. If an Obligor
under a Receivable with respect to which the Servicer has placed Force-Placed
Insurance fails to make scheduled payments of such Insurance Add-On Amount as
due, and the Servicer has determined that eventual payment of the Insurance Add-
On Amount is unlikely, the Servicer may, but shall not be required to, purchase
such Receivable from the Trust for the Purchase Amount on any subsequent
Determination Date. Any such Receivable, and any Receivable with respect to
which the Servicer has placed Force-Placed Insurance which has been paid in full
(excluding any Insurance Add-On Amounts) will be assigned to the Servicer.

     (d)  The Servicer may sue to enforce or collect upon the Insurance
Policies, in its own name, if possible, or as agent of the Trust. If the
Servicer elects to commence a legal proceeding

                                       34
<PAGE>

to enforce an Insurance Policy, the act of commencement shall be deemed to be an
automatic assignment of the rights of the Trust under such Insurance Policy to
the Servicer for purposes of collection only. If, however, in any enforcement
suit or legal proceeding it is held that the Servicer may not enforce an
Insurance Policy on the grounds that it is not a real party in interest or a
holder entitled to enforce the Insurance Policy, the Owner Trustee and/or the
Trust Collateral Agent, at the Servicer's expense, or the Seller, at the
Seller's expense, shall take such steps as the Servicer deems necessary to
enforce such Insurance Policy, including bringing suit in its name or the name
of the Trust and the Owner Trustee and/or the Trust Collateral Agent for the
benefit of the Noteholders.

     (e)  The Servicer will cause itself and may cause the Trust Collateral
Agent to be named as named insured under all policies of Collateral Insurance.

     SECTION 4.5.   Maintenance of Security Interests in Vehicles.
                    ----------------------------------------------

     (a)  Consistent with the policies and procedures required by this
Agreement, the Servicer shall take such steps on behalf of the Trust as are
necessary to maintain perfection of the security interest created by each
Receivable in the related Financed Vehicle, including, but not limited to,
obtaining the execution by the Obligors and the recording, registering, filing,
re-recording, re-filing, and re-registering of all security agreements,
financing statements and continuation statements as are necessary to maintain
the security interest granted by the Obligors under the respective Receivables.
The Trust Collateral Agent hereby authorizes the Servicer, and the Servicer
agrees, to take any and all steps necessary to re-perfect such security interest
on behalf of the Trust as necessary because of the relocation of a Financed
Vehicle or for any other reason. In the event that the assignment of a
Receivable to the Trust is insufficient, without a notation on the related
Financed Vehicle's certificate of title, or without fulfilling any additional
administrative requirements under the laws of the state in which the Financed
Vehicle is located, to perfect a security interest in the related Financed
Vehicle in favor of the Trust, the Servicer hereby agrees that AmeriCredit's
designation as the secured party on the certificate of title is in its capacity
as Servicer as agent of the Trust.

     (b)  Upon the occurrence of an Insurance Agreement Event of Default, the
Insurer may (so long as an Insurer Default shall not have occurred and be
continuing) instruct the Trust Collateral Agent and the Servicer to take or
cause to be taken, or, if an Insurer Default shall have occurred, upon the
occurrence of a Servicer Termination Event, the Trust Collateral Agent and the
Servicer shall take or cause to be taken such action as may, in the opinion of
counsel to the Controlling Party, be necessary to perfect or re-perfect the
security interests in the Financed Vehicles securing the Receivables in the name
of the Trust by amending the title documents of such Financed Vehicles or by
such other reasonable means as may, in the opinion of counsel to the Controlling
Party, be necessary or prudent.

     AmeriCredit hereby agrees to pay all expenses related to such perfection or
reperfection and to take all action necessary therefor.  In addition, prior to
the occurrence of an Insurance Agreement Event of Default, the Controlling Party
may instruct the Trust Collateral Agent and the Servicer to take or cause to be
taken such action as may, in the opinion of counsel to the Controlling Party, be
necessary to perfect or re-perfect the security interest in the Financed
Vehicles underlying the Receivables in the name of the Trust, including by
amending the title

                                       35
<PAGE>

documents of such Financed Vehicles or by such other reasonable means as may, in
the opinion of counsel to the Controlling Party, be necessary or prudent;
provided, however, that if the Controlling Party requests that the title
--------  -------
documents be amended prior to the occurrence of an Insurance Agreement Event of
Default, the out-of-pocket expenses of the Servicer or the Trust Collateral
Agent in connection with such action shall be reimbursed to the Servicer or the
Trust Collateral Agent, as applicable, by the Controlling Party. AmeriCredit and
CP Funding hereby appoint the Trust Collateral Agent as their attorney-in-fact
to take any and all steps required to be performed by AmeriCredit or CP Funding
pursuant to this Section 4.5(b) (it being understood that and agreed that the
Trust Collateral Agent shall have no obligation to take such steps, except as
pursuant to the Basic Documents to which it is a party), including execution of
certificates of title or any other documents in the name and stead of
AmeriCredit or CP Funding, and the Trust Collateral Agent hereby accepts such
appointment.

     SECTION 4.6.   Covenants, Representations, and Warranties of Servicer. By
                    ------------------------------------------------------
its execution and delivery of this Agreement, the Servicer makes the following
representations, warranties and covenants on which the Trust Collateral Agent
relies in accepting the Receivables, on which the Trustee relies in
authenticating the Notes and on which the Insurer relies in issuing the Note
Policy.

     (a)   The Servicer covenants as follows:

         (i)    Liens in Force.  The Financed Vehicle securing each Receivable
                --------------
     shall not be released in whole or in part from the security interest
     granted by the Receivable, except upon payment in full of the Receivable or
     as otherwise contemplated herein;

         (ii)   No Impairment.  The Servicer shall do nothing to impair the
                -------------
     rights of the Trust or the Noteholders in the Receivables, the Dealer
     Agreements, the Dealer Assignments, the Insurance Policies or the Other
     Conveyed Property except as otherwise expressly provided herein;

         (iii)  No Amendments.  The Servicer shall not extend or otherwise
                -------------
     amend the terms of any Receivable, except in accordance with Section 4.2;
     and

          (iv)  Restrictions on Liens.  The Servicer shall not (i) create,
                ---------------------
     incur or suffer to exist, or agree to create, incur or suffer to exist, or
     consent to cause or permit in the future (upon the happening of a
     contingency or otherwise) the creation, incurrence or existence of any Lien
     or restriction on transferability of the Receivables except for the Lien in
     favor of the Trust Collateral Agent for the benefit of the Noteholders and
     Insurer, the Lien imposed by the Spread Account Agreement Supplement in
     favor of the Collateral Agent for the benefit of the Trust Collateral Agent
     and Insurer, and the restrictions on transferability imposed by this
     Agreement or (ii) sign or file under the Uniform Commercial Code of any
     jurisdiction any financing statement which names AmeriCredit or the
     Servicer as a debtor, or sign any security agreement authorizing any
     secured party thereunder to file such financing statement, with respect to
     the Receivables, except in each case any such instrument solely securing
     the rights and preserving the Lien of the Trust Collateral Agent, for the
     benefit of the Noteholders and the Insurer.

                                       36
<PAGE>

     (b)  The Servicer represents, warrants and covenants as of the Closing Date
as to itself that the representations and warranties set forth on the Schedule
of Representations attached hereto as Schedule B are true and correct, provided
that such representations and warranties contained therein and herein shall not
apply to any entity other than AmeriCredit.

     SECTION 4.7.  Purchase of Receivables Upon Breach of Covenant.  Upon
                   -----------------------------------------------
discovery by any of the Servicer, the Insurer, a Responsible Officer of the
Trust Collateral Agent, the Owner Trustee or a Responsible Officer of the
Trustee of a breach of any of the covenants set forth in Sections 4.5(a) or
4.6(a), the party discovering such breach shall give prompt written notice to
the others; provided, however, that the failure to give any such notice shall
            --------  -------
not affect any obligation of AmeriCredit as Servicer under this Section.  As of
the second Accounting Date following its discovery or receipt of notice of any
breach of any covenant set forth in Sections 4.5(a) or 4.6(a) which materially
and adversely affects the interests of the Noteholders or the Insurer in any
Receivable (including any Liquidated Receivable) (or, at AmeriCredit's election,
the first Accounting Date so following) or the related Financed Vehicle,
AmeriCredit shall, unless such breach shall have been cured in all material
respects, purchase from the Trust the Receivable affected by such breach and, on
the related Determination Date, AmeriCredit shall pay the related Purchase
Amount.  It is understood and agreed that the obligation of AmeriCredit to
purchase any Receivable (including any Liquidated Receivable) with respect to
which such a breach has occurred and is continuing shall, if such obligation is
fulfilled, constitute the sole remedy against AmeriCredit for such breach
available to the Insurer, the Noteholders, the Owner Trustee or the Trust
Collateral Agent; provided, however, that AmeriCredit shall indemnify the Trust,
                  --------  -------
the Backup Servicer, the Collateral Agent, the Insurer, the Owner Trustee, the
Trust Collateral Agent, the Trustee and the Noteholders 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 breach.  This section shall survive the termination of this
Agreement and the earlier removal or resignation of the Trustee and/or the Trust
Collateral Agent and/or the Backup Servicer.

     SECTION 4.8.  Total Servicing Fee; Payment of Certain Expenses by Servicer.
                   ------------------------------------------------------------
On each Distribution Date, the Servicer shall be entitled to receive out of
the Collection Account the Base Servicing Fee and any Supplemental Servicing Fee
for the related Collection Period (together, the "Servicing Fee") pursuant to
Section 5.7.  The Servicer shall be required to pay all expenses incurred by it
in connection with its activities under this Agreement (including taxes imposed
on the Servicer, expenses incurred in connection with distributions and reports
made by the Servicer to Noteholders or the Insurer and all other fees and
expenses of the Owner Trustee, the Collateral Agent, the Backup Servicer, the
Trust Collateral Agent or the Trustee, except taxes levied or assessed against
the Trust, and claims against the Trust in respect of indemnification, which
taxes and claims in respect of indemnification against the Trust are expressly
stated to be for the account of AmeriCredit).  The Servicer shall be liable for
the fees and expenses of the Owner Trustee, the Backup Servicer, the Trust
Collateral Agent, the Trustee, the Custodian, the Backup Servicer, the
Collateral Agent, the Lockbox Bank (and any fees under the Lockbox Agreement)
and the Independent Accountants.  Notwithstanding the foregoing, if the Servicer
shall not be AmeriCredit, a successor to AmeriCredit as Servicer including the
backup servicer permitted by Section 9.3 shall not be liable for taxes levied or
assessed against the Trust or claims against the Trust in respect of
indemnification, or the fees and expenses referred to above.

                   -------------------------------------------------
Certificate.
------------

     (a)  No later than 10:00 am. Eastern time on each Preliminary Determination

     (c)  In the event that the Distribution Date is the date described in

longer the Servicer), then the information required by the Preliminary
Servicer's Certificate shall be added to the information required by the
Servicer's Certificate, and the expanded Servicer's Certificate shall be
delivered as required by paragraph (b) above.

of its performance under this Agreement has been made under such officer's
supervision, and (ii) to such officer's knowledge, based on such review, the
Servicer has fulfilled all its obligations under this Agreement throughout such
period, or, if there has been a default in the fulfillment of any such
obligation, specifying each such default known to such officer and the nature
and status thereof.

     (b)  The Servicer shall deliver to the Trustee, the Owner Trustee, the
Trust Collateral Agent, the Backup Servicer, the Insurer, the Collateral Agent,
and each Rating Agency, promptly after having obtained knowledge thereof, but in
no event later than two (2) Business Days thereafter, written notice in an

(which period shall not be less than six months)), a statement (the
"Accountants' Report") addressed to the Board of Directors of the Servicer, to
the Trustee, the Owner Trustee, the Trust Collateral Agent, the Backup Servicer
and to the Insurer, to the effect that such firm has audited the books and
records of AmeriCredit Corp., in which the Servicer is included as a
consolidated subsidiary, and issued its report thereon in connection with the

that (1) such audit was made in accordance with generally accepted auditing
standards, and accordingly included such tests of the accounting records and
such other auditing procedures as such firm considered necessary in the
circumstances; (2) the firm is independent of the Seller and the Servicer within
the meaning of the Code of Professional Ethics of the American Institute of

<PAGE>

Trust Collateral Agent, the Backup Servicer and the Insurer reasonable access to
the documentation regarding the Receivables. In each case, such access shall be
afforded without charge but only upon reasonable request and during normal
business hours. Nothing in this Section shall affect the obligation of the
Servicer to observe any applicable law prohibiting disclosure of information
regarding the Obligors, and the failure of the Servicer to provide access as
provided in this Section as a result of such obligation shall not constitute a
breach of this Section.

     SECTION 4.13.  Monthly Tape.  On or before the Insured Distribution Date,
                    ------------
but in no event later than the seventh calendar day, of each month, the Servicer

tape and a diskette (or any other electronic transmission acceptable to the
Trust Collateral Agent and the Backup Servicer) in a format acceptable to the
Trust Collateral Agent and the Backup Servicer containing the information with
respect to the Receivables as of the preceding Accounting Date necessary for
preparation of the Servicer's Certificate relating to the immediately preceding
Determination Date and necessary to determine the application of collections as

Backup Servicer) to verify the Servicer's Certificate delivered by the Servicer,
and the Backup Servicer shall certify to the Controlling Party that it has
verified the Servicer's Certificate in accordance with this Section and shall
notify the Servicer and the Controlling Party of any discrepancies, in each
case, on or before the second Business Day following the Insured Distribution

Servicer and the Backup Servicer shall attempt to reconcile such discrepancies
prior to the next succeeding Distribution Date, but in the absence of a
reconciliation, the Servicer's Certificate shall control for the purpose of
calculations and distributions with respect to the next succeeding Distribution
Date. In the event that the Backup Servicer and the Servicer are unable to
reconcile discrepancies with respect to a Servicer's Certificate by the next
succeeding Distribution Date, the Servicer shall cause the Independent
Accountants, at the Servicer's expense, to audit the Servicer's Certificate and,
prior to the last day of the month after the month in which such Servicer's
Certificate was delivered, reconcile the discrepancies. The effect, if any, of
such reconciliation shall be reflected in the Preliminary Servicer's Certificate
for the next succeeding Distribution Date, and/or the Servicer's Certificate for
such next succeeding Determination Date. In addition, upon the occurrence of a
Servicer Termination Event the Servicer shall, if so requested by the
Controlling Party, deliver to the Backup Servicer its Collection Records and its
Monthly Records within 15 days after demand therefor and a computer tape
containing as of the close of business on the date of demand all of the data
maintained by the Servicer in computer format in connection with servicing the
Receivables. Other than the duties specifically set forth in this Agreement, the
Backup Servicer shall have no obligations hereunder, including, without
limitation, to supervise, verify, monitor or administer the performance of the
Servicer. The Backup Servicer shall have no liability for any actions taken or
omitted by the Servicer.

     SECTION 4.14.  Retention and Termination of Servicer.  The Servicer hereby
                    -------------------------------------
covenants and agrees to act as such under this Agreement for an initial term,
commencing on the Closing Date and ending on September 30, 2000, which term
shall be subject to extension by the Controlling Party for successive quarterly
terms ending on each successive December 31, March 31 and June 30 (or, pursuant
to revocable written standing instructions from time to time to the Servicer and
the Trust Collateral Agent for any specified number of terms greater than one),
until

                                       40
<PAGE>

the Notes and the Securities are paid in full. Each such notice (including each
notice pursuant to standing instructions, which shall be deemed delivered at the
end of successive quarterly terms for so long as such instructions are in
effect) (a "Servicer Extension Notice") shall be delivered by the Insurer to the
Trust Collateral Agent and the Servicer. The Servicer hereby agrees that, as of
the date hereof and upon its receipt of any such Servicer Extension Notice, the
Servicer shall become bound, for the initial term beginning on the Closing Date
and for the duration of the term covered by such Servicer Extension Notice, to
continue as the Servicer subject to and in accordance with the other provisions
of this Agreement. Until such time as an Insurer Default shall have occurred and
be continuing the Trust Collateral Agent agrees that if as of the fifteenth day
prior to the last day of any term of the Servicer the Trust Collateral Agent
shall not have received any Servicer Extension Notice from the Insurer, the
Trust Collateral Agent will, within five days thereafter, give written notice of
such non-receipt to the Insurer and the Servicer.

     SECTION 4.15.  Fidelity Bond and Errors and Omissions Policy.  The Servicer
                    ---------------------------------------------
has obtained, and shall continue to maintain in full force and effect, a
Fidelity Bond and Errors and Omissions Policy of a type and in such amount as is
customary for servicers engaged in the business of servicing automobile
receivables.

     SECTION 5.1.   Establishment of Trust Accounts.
                    --------------------------------

     (a)   (i) The Trust Collateral Agent, on behalf of the Noteholders and the
Insurer, shall establish and maintain in its own name an Eligible Deposit
Account (the "Collection Account"), bearing a designation clearly indicating
that the funds deposited therein are held for the benefit of the Trust
Collateral Agent on behalf of the Noteholders and the Insurer. The Collection
Account shall initially be established with the Trust Collateral Agent.

     (ii)  The Trust Collateral Agent, on behalf of the Noteholders, shall
establish and maintain in its own name an Eligible Deposit Account (the "Note
Distribution Account"), bearing a designation clearly indicating that the funds
deposited therein are held for the benefit of the Trust Collateral Agent on
behalf of the Noteholders and the Insurer.  The Note Distribution Account shall
initially be established with the Trust Collateral Agent.

     (iii) The Trust Collateral Agent, on behalf of the Noteholders and the
Insurer, shall establish and maintain in its own name an Eligible Deposit
Account (the "Pre-Funding Account"), bearing a designation clearly indicating
that the funds deposited therein are held for the benefit of the Trust
Collateral Agent on behalf of the Noteholders and the Insurer.  The Pre-Funding
Account shall initially be established with the Trust Collateral Agent.

     (b)   Funds on deposit in the Collection Account, the Pre-Funding Account,
the Note Distribution Account and the Capitalized Interest Account
(collectively, the "Trust Accounts") and the Lockbox Accounts shall be invested
by the Trust Collateral Agent (or any custodian with respect to funds on deposit
in any such account) in Eligible Investments selected in writing by

                                       41
<PAGE>

the Servicer (pursuant to standing instructions or otherwise). All such Eligible
Investments shall be held by or on behalf of the Trust Collateral Agent for the
benefit of the Noteholders and the Insurer, as applicable. Other than as
permitted by the Rating Agencies and the Insurer, funds on deposit in any
Account shall be invested in Eligible Investments that will mature so that such
funds will be available at the close of business on the Business Day immediately
preceding the following Distribution Date or, if earlier, on the following
Insured Distribution Date. Funds deposited in a Trust Account on the day
immediately preceding a Distribution Date or an Insured Distribution Date upon
the maturity of any Eligible Investments are required to be invested overnight.
All Eligible Investments will be held to maturity.

     (c)  All investment earnings of moneys deposited in the Trust Accounts
shall be deposited (or caused to be deposited) by the Trust Collateral Agent in
the Collection Account, and any loss resulting from such investments shall be
charged to such account. The Servicer will not direct the Trust Collateral Agent
to make any investment of any funds held in any of the Trust Accounts unless the
security interest granted and perfected in such account will continue to be
perfected in such investment, in either case without any further action by any
Person, and, in connection with any direction to the Trust Collateral Agent to
make any such investment, if requested by the Trust Collateral Agent, the
Servicer shall deliver to the Trust Collateral Agent an Opinion of Counsel,
acceptable to the Trust Collateral Agent, to such effect.

     (d)  The Trust Collateral Agent shall not in any way be held liable by
reason of any insufficiency in any of the Trust Accounts resulting from any loss
on any Eligible Investment included therein except for losses attributable to
the Trust Collateral Agent's negligence or bad faith or its failure to make
payments on such Eligible Investments issued by the Trust Collateral Agent, in
its commercial capacity as principal obligor and not as trustee, in accordance
with their terms.

     (e)  If (i) the Servicer shall have failed to give investment directions in
writing for any funds on deposit in the Trust Accounts to the Trust Collateral
Agent by 1:00 p.m. Eastern Time (or such other time as may be agreed by the
Issuer and Trust Collateral Agent) on any Business Day; or (ii) a Default or
Event of Default shall have occurred and be continuing with respect to the Notes
but the Notes shall not have been declared due and payable, or, if such Notes
shall have been declared due and payable following an Event of Default, amounts
collected or receivable from the Trust Property are being applied as if there
had not been such a declaration; then the Trust Collateral Agent shall, to the
fullest extent practicable, invest and reinvest funds in the Trust Accounts in
the investment described in clause (g) of the definition of Eligible
Investments.

     (f)  (i) The Trust Collateral Agent shall possess all right, title and
interest in all funds on deposit from time to time in the Trust Accounts and in
all proceeds thereof (excluding all Investment Earnings on the Collection
Account) and all such funds, investments, proceeds and income shall be part of
the Owner Trust Estate. Except as otherwise provided herein, the Trust Accounts
shall be under the sole dominion and control of the Trust Collateral Agent for
the benefit of the Noteholders, as the case may be, and the Insurer. If, at any
time, any of the Trust Accounts ceases to be an Eligible Deposit Account, the
Trust Collateral Agent (or the Servicer on its behalf) shall within five
Business Days (or such longer period as to which each Rating Agency and the
Insurer may consent) establish a new Trust Account as an Eligible Deposit

                                       42
<PAGE>

Account and shall transfer any cash and/or any investments to such new Trust
Account. In connection with the foregoing, the Servicer agrees that, in the
event that any of the Trust Accounts are not accounts with the Trust Collateral
Agent, the Servicer shall notify the Trust Collateral Agent in writing promptly
upon any of such Trust Accounts ceasing to be an Eligible Deposit Account.

     (ii)  With respect to the Trust Account Property, the Trust Collateral
Agent agrees that:

                  (A) any Trust Account Property that is held in deposit

     are not sufficient funds in the Note Distribution Account to pay the entire
     amount of accrued and unpaid interest then due on each Class of Notes, the
     amount in the Note Distribution Account shall be applied to the payment of
     such interest on each Class of Notes pro rata on the basis of the amount of
     accrued and unpaid interest due on each Class of Notes;

          (ii) any amounts deposited in the Note Distribution Account with
     respect to the Note Prepayment Amount, shall be distributed to the Holders
     of the Class A-1 Notes, the Class A-2 Notes, the Class A-3 Notes and the

                                       47
<PAGE>

     represented by the relative outstanding principal balance of each Class of
     Notes; provided, that if the aggregate remaining amount in the Pre-Funding
     Account is $100,000 or less, such amount will be applied exclusively to
     reduce the outstanding principal balance of the Class of Notes then
     entitled to receive distributions of principal;

         (iii) The Principal Distributable Amount shall be distributed as
     follows:

     (1)  to the Holders of the Class A-1 Notes with the total amount paid out
          on each Distribution Date until the outstanding principal balance of
          the Class A-1 Notes has been reduced to zero;

     (2)  to the Holders of the Class A-2 Notes with the total amount paid out
          on each Distribution Date until the outstanding principal balance of
          the Class A-2 Notes has been reduced to zero;

     (3)  to the Holders of the Class A-3 Notes with the total amount paid out
          on each Distribution Date until the outstanding principal balance of
          the Class A-3 Notes has been reduced to zero; and

amount otherwise distributable to the Noteholder in accordance with this
Section. The Trust Collateral Agent is hereby authorized and directed to retain
from amounts otherwise distributable to the Noteholders sufficient funds for the
payment of any tax attributable to the Trust (but such authorization shall not
prevent the Trust Collateral Agent from contesting any such tax in appropriate
proceedings, and withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings). The amount of any withholding tax imposed with
respect to a Noteholder shall be treated as cash distributed to such Noteholder
at the time it is withheld by the Trust and remitted to the appropriate taxing
authority. If there is a possibility that withholding tax is payable with
respect to a distribution (such as a distribution to a non-US Noteholder), the
Trust Collateral Agent may in its sole discretion withhold such amounts in
accordance with this clause (c). In the event that a Noteholder wishes to apply
for a refund of any such withholding tax, the Trust Collateral Agent shall
reasonably cooperate with such Noteholder in making such claim so long as such
Noteholder agrees to reimburse the Trust Collateral Agent for any out-of-pocket
expenses (including legal fees and expenses) incurred.

     (d)  Distributions required to be made to Noteholders on any Distribution
Date any Insured Distribution Date shall be made to each Noteholder of record on

denomination of not less than $1,000,000 or (ii) by check mailed to such
Noteholder at the address of such holder appearing in the Note Register.

(whether on the Final Scheduled Distribution Date or otherwise) will be payable
only upon presentation and surrender of such Note at the office or agency
maintained for that purpose by the Note Registrar pursuant to Section 2.4 of the
Indenture.

     (e)  Subject to Section 5.1 and this section, monies received by the Trust
Collateral Agent hereunder need not be segregated in any manner except to the
extent required by law and may be deposited under such general conditions as may
be prescribed by law, and the Trust Collateral Agent shall not be liable for any
interest thereon.

Trust Collateral Agent in writing to withdraw from the Pre-Funding Account (i)

which the Funding Period ends after giving effect to any reductions in the Pre-
Funded Amount on such date, the Servicer shall instruct the Trust Collateral
Agent in writing to withdraw from the Pre-Funding Account on the Mandatory
Redemption Date the Pre-Funded Amount (exclusive of any Pre-Funding Earnings)
and deposit an amount equal to the Note Prepayment Amount in the Note
Distribution Account.

     SECTION 5.10.  Statements to Noteholders.
                    -------------------------

backedsecuritizations. Persons that are entitled to receive such statements but

to receive such statements. The Trust Collateral Agent shall provide
notification of any such change to all parties entitled to receive such
statements in the manner described in Section 12.3 hereof, Section 11.4 of the
Indenture or Section 11.5 of the Indenture, as appropriate.

     SECTION 5.11.  Optional Deposits by the Insurer.  The Insurer shall at any
                    --------------------------------
time, and from time to time, with respect to an Insured Distribution Date, have
the option (but shall not be required, except in accordance with the terms of
the Note Policy) to deliver amounts to the Trust Collateral Agent for deposit
into the Collection Account for any of the following purposes: (i) to provide
funds in respect of the payment of fees or expenses of any provider of services
to the

                                       50

     SECTION 5.12.  Determination of LIBOR.  The Trust Collateral Agent will
                    ----------------------
determine LIBOR for purposes of calculating the Interest Rate for the Class A-3
Notes and the Class A-4 Notes on May 23, 2000 for the period from the Closing
Date to the first Distribution Date, and for each given Interest Period
thereafter, on the second London Business Day prior to the prior Distribution
Date (each, a "LIBOR Determination Date"). For purposes of calculating LIBOR, a
business day means a Business Day and a day on which banking institutions in the
City of London, England are not required or authorized by law to be closed.

     "LIBOR" means, with respect to any Interest Period, the London interbank
offered rate for deposits in the U.S. dollars having a maturity of one month
commencing on the related LIBOR Determination Date (the "Index Maturity") which
appears on Telerate Page 3750 as of 11:00 a.m., London time, on such LIBOR
Determination Date.  If such rate does not appear on the Telerate page 3750, the
rate for that day will be determined on the basis of the rate at which deposits
in U.S. dollars, having the Index Maturity and in a principal amount of not less
than U.S. $1,000,000 are offered at approximately 11:00 a.m., London Time, on
such LIBOR Determination Date to prime banks in the London interbank market by
the Reference Banks.  The Trust Collateral Agent will request the principal
London office of each of such Reference Banks to provide a quotation of its
rate.  If at least two such quotations are provided, the rate for that day will
be the arithmetic mean, rounded upward, if necessary, to the nearest 1/100,000
of 1% (0.0000001), with five-one millionths of a percentage point rounded
upward, of all such quotations.  If fewer than two such quotations are provided,
the rate for that day will be the arithmetic mean, rounded upward of necessary
to the nearest 1/100,000 of 1% (0.0000001), with five-one millionths of a
percentage point rounded upward, of the offered per annum rates that one or more
leading banks in New York City, selected by the Trust Collateral Agent, are
quoting as of approximately 11:00 a.m., Eastern time, on such LIBOR
Determination Date to leading European banks for United States dollar deposits
for the Index Maturity; provided that if the banks selected as aforesaid are not
quoting as mentioned in this sentence, LIBOR in effect for the applicable

     (a)  In the event that the Trust Collateral Agent has delivered a
Deficiency Notice with respect to any Determination Date pursuant to Section 5.5
hereof, the Trust Collateral Agent shall on the related Draw Date determine the
Note Policy Claim Amount for the related Insured Distribution Date. If the Note
Policy Claim Amount for such Insured Distribution Date is greater than zero, the
Trust Collateral Agent shall furnish to the Insurer no later than 12:00 noon
Eastern time on the related Draw Date a completed Notice of Claim (as defined in
(b) below) in the amount of the Note Policy Claim Amount. Amounts paid by the
Insurer pursuant to a claim submitted under this Section shall be deposited by
the Trust Collateral Agent into the Note Distribution Account for payment to
Noteholders on the related Insured Distribution Date.

     (b)  Any notice delivered by the Trust Collateral Agent to the Insurer
pursuant to subsection 6.1(a) shall specify the Note Policy Claim Amount claimed
under the Note Policy and shall constitute a "Notice of Claim" under the Note
Policy. In accordance with the provisions of the Note Policy, the Insurer is
required to pay to the Trust Collateral Agent the Note Policy Claim Amount
properly claimed thereunder by 10:00 a.m., Eastern time, on the later of (i) the
third Business Day following receipt on a Business Day of the Notice of Claim,
and (ii) the applicable Insured Distribution Date. Any payment made by the
Insurer under the Note Policy shall be applied solely to the payment of the
Notes, and for no other purpose.

     (c)  The Trust Collateral Agent shall (i) receive as attorney-in-fact of
each Noteholder any Note Policy Claim Amount from the Insurer and (ii) deposit
the same in the Collection Account for distribution to Noteholders. Any and all
Note Policy Claim Amounts disbursed by the Trust Collateral Agent from claims
made under the Note Policy shall not be considered payment by the Trust or from
the Spread Account with respect to such Notes, and shall not discharge the
obligations of the Trust with respect thereto. The Insurer shall, to the extent
it makes any payment with respect to the Notes, become subrogated to the rights
of the recipients of such payments to the extent of such payments. Subject to
and conditioned upon any payment with respect to the Notes by or on behalf of
the Insurer, the Trust Collateral Agent shall assign to the Insurer all rights
to the payment of interest or principal with respect to the Notes which are then
due for payment to the extent of all payments made by the Insurer, and the
Insurer may exercise any option, vote, right, power or the like with respect to
the Notes to the extent that it has made payment pursuant to the Note Policy. To
evidence such subrogation, the Note Registrar shall note the Insurer's rights as
subrogee upon the register of Noteholders upon receipt from the Insurer of proof
of payment by the Insurer of any Noteholders' Interest Distributable Amount or
Noteholders' Principal Distributable Amount. The foregoing subrogation shall in
all cases be subject to the rights of the Noteholders to receive all Scheduled
Payments (as defined in the Note Policy) in respect of the Notes.

     (d)  The Trust Collateral Agent shall keep a complete and accurate record
of all funds deposited by the Insurer into the Collection Account and the
allocation of such funds to payment of interest on and principal paid in respect
of any Note. The Insurer shall have the right to inspect such records at
reasonable times upon one Business Day's prior notice to the Trust Collateral
Agent.

     (e)  The Trust Collateral Agent shall be entitled to enforce on behalf of
the Noteholders the obligations of the Insurer under the Note Policy.
Notwithstanding any other provision of this

                                       52

Agreement or any Basic Document, the Noteholders are not entitled to institute
proceedings directly against the Insurer.

     SECTION 6.2.   Preference Claims.
                    ------------------

     (a)  In the event that the Trust Collateral Agent has received a certified
copy of an order of the appropriate court that any Scheduled Payment (as defined
in the Note Policy) paid on a Note has been avoided in whole or in part as a
preference payment under applicable bankruptcy law, the Trust Collateral Agent
shall so notify the Insurer, shall comply with the provisions of the Note Policy
to obtain payment by the Insurer of such avoided payment, and shall, at the time
it provides notice to the Insurer, notify Holders of the Notes by mail that, in
the event that any Noteholder's payment is so recoverable, such Noteholder will
be entitled to payment pursuant to the terms of the Note Policy. The Trust
Collateral Agent shall furnish to the Insurer its records evidencing the
payments of principal of and interest on Notes, if any, which have been made by
the Trust Collateral Agent and subsequently recovered from Noteholders, and the
dates on which such payments were made. Pursuant to the terms of the Note
Policy, the Insurer will make such payment on behalf of the Noteholder to the
receiver, conservator, debtor-in-possession or trustee in bankruptcy named in
the Order (as defined in the Note Policy) and not to the Trust Collateral Agent
or any Noteholder directly (unless a Noteholder has previously paid such payment
to the receiver, conservator, debtor-in-possession or trustee in bankruptcy, in
which case the Insurer will make such payment to the Trust Collateral Agent for
distribution to such Noteholder upon proof of such payment reasonably
satisfactory to the Insurer).

     (b)  The Trust Collateral Agent shall promptly notify the Insurer of any
proceeding or the institution of any action (of which a Responsible Officer of
the Trust Collateral Agent has actual knowledge) seeking the avoidance as a
preferential transfer under applicable bankruptcy, insolvency, receivership,
rehabilitation or similar law (a "Note Preference Claim") of any distribution
made with respect to the Notes. Each Holder, by its purchase of Notes, and the
Trust Collateral Agent hereby agree that so long as an Insurer Default shall not
have occurred and be continuing, the Insurer may at any time during the
continuation of any proceeding relating to a Preference Claim direct all matters
relating to such Preference Claim, including, without limitation, (i) the
direction of any appeal of any order relating to any Preference Claim and (ii)
the posting of any surety, supersedes as or performance bond pending any such
appeal at the expense of the Insurer, but subject to reimbursement as provided
in the Insurance Agreement. In addition, and without limitation of the
foregoing, as set forth in Section 6.1(c), the Insurer shall be subrogated to,
and each Noteholder and the Trust Collateral Agent hereby delegate and assign,
to the fullest extent permitted by law, the rights of the trustee and each
Noteholder in the conduct of any proceeding with respect to a Preference Claim,
including, without limitation, all rights of any party to an adversary
proceeding action with respect to any court order issued in connection with any
such Preference Claim.

     SECTION 6.3.   Surrender of Policy.  The Trust Collateral Agent shall
                    -------------------
surrender the Note Policy to the Insurer for cancellation upon the expiration of
such policy in accordance with the terms thereof.

defend and hold harmless the Trust, the Trustee, the Trust Collateral Agent, the
Owner Trustee, the Backup Servicer, the Insurer, their respective officers,
directors, agents and employees and the Noteholders from and against any taxes
that may at any time be asserted against any of such parties with respect to the

and hold harmless the Trust, the Trustee, the Trust Collateral Agent, the Owner
Trustee, the Backup Servicer, the Insurer, their respective officers, directors,

or the Noteholders by reason of the breach of this Agreement by the Servicer,
the negligence, misfeasance, or bad faith of the Servicer in the performance of
its duties under this Agreement or by reason of reckless disregard of its
obligations and duties under this Agreement.

     (e)  AmeriCredit shall indemnify, defend and hold harmless the Trust, the
Trustee, the Trust Collateral Agent, the Owner Trustee, the Backup Servicer, the
Insurer, their respective officers, directors, agents and employees and the
Noteholders from and against any loss, liability or expense incurred by reason

Collateral Agent.

loss, liability or expense, (other than overhead and expenses incurred in the

     SECTION 8.3.   Merger or Consolidation of, or Assumption of the Obligations
                    ------------------------------------------------------------
of the Servicer or Backup Servicer.
----------------------------------

     (a)  AmeriCredit shall not merge or consolidate with any other person,
convey, transfer or lease substantially all its assets as an entirety to another
Person, or permit any other Person to become the successor to AmeriCredit's
business unless, after the merger, consolidation, conveyance, transfer, lease or
succession, the successor or surviving entity shall be capable of fulfilling the
duties of AmeriCredit contained in this Agreement and shall be acceptable to the
Controlling Party, and, if an Insurer Default shall have occurred and be
continuing, shall be an Eligible Servicer. Any corporation (i) into which
AmeriCredit may be merged or consolidated, (ii) resulting from any merger or
consolidation to which AmeriCredit shall be a party, (iii) which acquires by
conveyance, transfer, or lease substantially all of the assets of AmeriCredit,
or (iv) succeeding to the business of AmeriCredit, in any of the foregoing cases
shall execute an agreement of assumption to perform every obligation of
AmeriCredit under this Agreement and, whether or not such assumption agreement
is executed, shall be the successor to AmeriCredit under this Agreement without
the execution or filing of any paper or any further act on the part of any of
the parties to this Agreement, anything in this Agreement to the contrary
notwithstanding; provided, however, that nothing contained herein shall be
                 --------  -------
deemed to release AmeriCredit from any obligation. AmeriCredit shall provide
notice of any merger, consolidation or succession pursuant to this Section to
the Owner Trustee, the Trust Collateral Agent, the Noteholders, the Insurer and
each Rating Agency. Notwithstanding the foregoing, AmeriCredit shall not merge
or consolidate with any other Person or permit any other Person to become a
successor to AmeriCredit's business, unless (x) immediately after giving effect
to such transaction, no representation or warranty made pursuant to Section 4.6
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
Insurance Agreement Event of Default shall have occurred and be continuing, (y)
AmeriCredit shall have delivered to the Owner Trustee, the Trust Collateral
Agent, Trustee, Backup Servicer and Collateral Agent, the Rating Agencies and
the Insurer 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 and that all conditions precedent, if any, provided for in
this Agreement relating to such transaction have been complied with, and (z)

                                       61
<PAGE>

AmeriCredit shall have delivered to the Owner Trustee, the Trust Collateral
Agent, the Rating Agencies and the Insurer 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 Trust in the Receivables
and the Other Conveyed Property and reciting the details of the filings or (B)
no such action shall be necessary to preserve and protect such interest.

     (b)  Any corporation (i) into which the Backup Servicer may be merged or
consolidated, (ii) resulting from any merger or consolidation to which the
Backup Servicer shall be a party, (iii) which acquires by conveyance, transfer
or lease substantially all of the assets of the Backup Servicer, or (iv)
succeeding to the business of the Backup Servicer, in any of the foregoing cases
shall execute an agreement of assumption to perform every obligation of the
Backup Servicer under this Agreement and, whether or not such assumption
agreement is executed, shall be the successor to the Backup Servicer under this
Agreement without the execution or filing of any paper or any further act on the
part of any of the parties to this Agreement, anything in this Agreement to the
contrary notwithstanding; provided, however, that nothing contained herein shall
be deemed to release the Backup Servicer from any obligation.

     SECTION 8.4.  Limitation on Liability of Servicer, Backup Servicer and
                   --------------------------------------------------------
Others.
-------

     (a)  Neither AmeriCredit, the Backup Servicer nor any of the directors or
officers or employees or agents of AmeriCredit or Backup Servicer shall be under
any liability to the Trust or the Noteholders, except as provided in this
Agreement, for any action taken or for refraining from the taking of any action
pursuant to this Agreement; provided, however, that this provision shall not
                            --------  -------
protect AmeriCredit, the Backup Servicer or any such person against any
liability that would otherwise be imposed by reason of a breach of this
Agreement or willful misfeasance, bad faith or negligence (excluding errors in
judgment) in the performance of duties; provided further that this provision
shall not affect any liability to indemnify the Trust Collateral Agent and the
Owner Trustee for costs, taxes, expenses, claims, liabilities, losses or damages
paid by the Trust Collateral Agent and the Owner Trustee, in their individual
capacities. AmeriCredit, the Backup Servicer and any director, officer, employee
or agent of AmeriCredit or Backup Servicer may rely in good faith on the written
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.

     (b)  The Backup Servicer shall not be liable for any obligation of the
Servicer contained in this Agreement or for any errors of the Servicer contained
in any computer tape, certificate or other data or document delivered to the
Backup Servicer hereunder or on which the Backup Servicer must rely in order to
perform its obligations hereunder, and the Owner Trustee, the Trustee, the Trust
Collateral Agent, the Collateral Agent, the Backup Servicer, the Seller and the
Insurer and the Noteholders shall look only to the Servicer to perform such
obligations. The Backup Servicer, Trust Collateral Agent, the Trustee, the
Collateral Agent, the Owner Trustee and the Custodian shall have no
responsibility and shall not be in default hereunder or incur any liability for
any failure, error, malfunction or any delay in carrying out any of their
respective duties under this Agreement if such failure or delay results from the
Backup Servicer acting in accordance with information prepared or supplied by a
Person other than the Backup Servicer (or contractual agents) or the failure of
any such other Person to prepare or provide such

                                       62
<PAGE>

information. The Backup Servicer shall have no responsibility, shall not be in
default and shall incur no liability for (i) any act or failure to act of any
third party (other than its contractual agents), including the Servicer or the
Controlling Party, (ii) any inaccuracy or omission in a notice or communication
received by the Backup Servicer from any third party (other than its contractual
agents), (iii) the invalidity or unenforceability of any Receivable under
applicable law, (iv) the breach or inaccuracy of any representation or warranty
made with respect to any Receivable, or (v) the acts or omissions of any
successor Backup Servicer.

     (c)  The parties expressly acknowledge and consent to Bank One, N.A. acting
in the possible dual capacity of Backup Servicer or successor Servicer and in
the capacity as Trust Collateral Agent. Bank One, N.A. may, in such dual or
other capacity, discharge its separate functions fully, without hindrance or
regard to conflict of interest principles, duty of loyalty principles or other
breach of fiduciary duties to the extent that any such conflict or breach arises
from the performance by Bank One, N.A. of express duties set forth in the this
Agreement in any of such capacities, all of which defenses, claims or assertions
are hereby expressly waived by the other parties hereto and the Noteholders
except in the case of gross negligence and willful misconduct by Bank One, N.A.

     SECTION 8.5.   Delegation of Duties.  The Servicer may delegate duties
                    --------------------
under this Agreement to an Affiliate of AmeriCredit with the prior written
consent of the Insurer (unless an Insurer Default shall have occurred and be
continuing), the Trust Collateral Agent, the Owner Trustee and the Backup
Servicer. The Servicer also may at any time perform through sub-contractors the
specific duties of (i) repossession of Financed Vehicles, (ii) tracking Financed
Vehicles' insurance and (iii) pursuing the collection of deficiency balances on
certain Liquidated Receivables, in each case, without the consent of the Insurer
and may perform other specific duties through such sub-contractors in accordance
with Servicer's customary servicing policies and procedures, with the prior
consent of the Insurer; provided, however, that no such delegation or sub-
                        --------  -------
contracting duties by the Servicer shall relieve the Servicer of its
responsibility with respect to such duties. So long as no Insurer Default shall
have occurred and be continuing neither AmeriCredit or any party acting as
Servicer hereunder shall appoint any subservicer hereunder without the prior
written consent of the Insurer, the Trustee and the Backup Servicer.

     SECTION 8.6.   Servicer and Backup Servicer Not to Resign.  Subject to the
                    ------------------------------------------
provisions of Section 8.3, neither the Servicer nor the Backup Servicer shall
resign from the obligations and duties imposed on it by this Agreement as
Servicer or Backup Servicer except upon a determination that by reason of a
change in legal requirements the performance of its duties under this Agreement
would cause it to be in violation of such legal requirements in a manner which
would have a material adverse effect on the Servicer or the Backup Servicer, as
the case may be, and the Insurer (so long as an Insurer Default shall not have
occurred and be continuing) or a Note Majority (if an Insurer Default shall have
occurred and be continuing) does not elect to waive the obligations of the
Servicer or the Backup Servicer, as the case may be, to perform the duties which
render it legally unable to act or to delegate those duties to another Person.
Any such determination permitting the resignation of the Servicer or Backup
Servicer shall be evidenced by an Opinion of Counsel to such effect delivered
and acceptable to the Trust Collateral Agent, the Owner Trustee and the Insurer
(unless an Insurer Default shall have occurred and be continuing). No
resignation of the Servicer shall become effective until, so long as no Insurer
Default shall have occurred and be continuing the Backup Servicer or an entity

                                       63
<PAGE>

acceptable to the Insurer shall have assumed the responsibilities and
obligations of the Servicer or, if an Insurer Default shall have occurred and be
continuing, the Backup Servicer or a successor Servicer that is an Eligible
Servicer shall have assumed the responsibilities and obligations of the
Servicer. No resignation of the Backup Servicer shall become effective until, so
long as no Insurer Default shall have occurred and be continuing, an entity
acceptable to the Insurer shall have assumed the responsibilities and
obligations of the Backup Servicer or, if an Insurer Default shall have occurred
and be continuing a Person that is an Eligible Servicer shall have assumed the
responsibilities and obligations of the Backup Servicer; provided, however, that
(i) in the event a successor Backup Servicer is not appointed within 60 days
after the Backup Servicer has given notice of its resignation and has provided
the Opinion of Counsel required by this Section, the Backup Servicer may
petition a court for its removal, (ii) the Backup Servicer may resign with the
written consent of the Insurer and (iii) if Bank One, N.A. resigns as the
Trustee under the Indenture it will no longer be the Backup Servicer.

                                    -------

     SECTION 9.1.   Servicer Termination Event.  For purposes of this Agreement,
                    --------------------------
each of the following shall constitute a "Servicer Termination Event":

     (a)  Any failure by the Servicer to deliver to the Trust Collateral Agent
for distribution to Noteholders any proceeds or payment required to be so
delivered under the terms of this Agreement that continues unremedied for a
period of two Business Days (one Business Day with respect to payment of
Purchase Amounts) after written notice is received by the Servicer from the
Trust Collateral Agent or (unless an Insurer Default shall have occurred and be
continuing) the Insurer or after discovery of such failure by a Responsible
Officer of the Servicer;

     (b)  Failure by the Servicer to deliver to the Trust Collateral Agent and
(so long as an Insurer Default shall not have occurred and be continuing) the
Insurer the Servicer's Certificate by the fourth Business Day prior to the

covenants and agreements set forth in Section 8.3(a);

     (c)  Failure on the part of the Servicer duly to observe or perform any
other covenants or agreements of the Servicer set forth in this Agreement, which
failure (i) materially and adversely affects the rights of Noteholders
(determined without regard to the availability of funds under the Note Policy),
or of the Insurer (unless an Insurer Default shall have occurred and be
continuing), and (ii) continues unremedied for a period of 30 days after
knowledge thereof by the Servicer or after the date on which written notice of
such failure, requiring the same to be remedied, shall have been given to the
Servicer by the Trust Collateral Agent or the Insurer (or, if an Insurer Default
shall have occurred and be continuing by any Noteholder);

     (d)  The entry of a decree or order for relief by a court or regulatory
authority having jurisdiction in respect of the Servicer in an involuntary case
under the federal bankruptcy laws, as now or hereafter in effect, or another

a receiver, liquidator, assignee, trustee, custodian, sequestrator or other

ordering the winding up or liquidation of the affairs of the Servicer and the
continuance of any such decree or order unstayed and in effect for a period of
60 consecutive days or the commencement of an involuntary case under the federal
bankruptcy laws, as now or hereinafter in effect, or another present or future
federal or state bankruptcy, insolvency or similar law and such case is not
dismissed within 60 days; or

     (e)  The commencement by the Servicer of a voluntary case under the federal
bankruptcy laws, as now or hereafter in effect, or any other present or future,
federal or state, bankruptcy, insolvency or similar law, or the consent by the
Servicer to the appointment of or taking possession by a receiver, liquidator,
assignee, trustee, custodian, sequestrator or other similar official of the
Servicer or of any substantial part of its property or the making by the
Servicer of an assignment for the benefit of creditors or the failure by the
Servicer generally to pay its debts as such debts become due or the taking of
corporate action by the Servicer in furtherance of any of the foregoing; or

     (f)  Any representation, warranty or statement of the Servicer made in this
Agreement or any certificate, report or other writing delivered pursuant hereto
shall prove to be incorrect in any material respect as of the time when the same
shall have been made, and the incorrectness of such representation, warranty or
statement has a material adverse effect on the Trust or the Noteholders and,
within 30 days after knowledge thereof by the Servicer or after written notice
thereof shall have been given to the Servicer by the Trust Collateral Agent or
the Insurer (or, if an Insurer Default shall have occurred and be continuing, a
Noteholder), the circumstances or condition in respect of which such
representation, warranty or statement was incorrect shall not have been
eliminated or otherwise cured; or

     (g)  So long as an Insurer Default shall not have occurred and be
continuing, the Insurer shall not have delivered a Servicer Extension Notice
pursuant to Section 4.14; or

     (h)  So long as an Insurer Default shall not have occurred and be
continuing, an Insurance Agreement Event of Default occurs or an Event of
Default under any other Insurance and Indemnity Agreement relating to any other

     (i)  A claim is made under the Note Policy.

     SECTION 9.2.   Consequences of a Servicer Termination Event.  If a Servicer
                    --------------------------------------------
Termination Event shall occur and be continuing, the Insurer (or, if an Insurer
Default shall have occurred and be continuing either the Trust Collateral Agent,
(to the extent it has knowledge thereof) a Note Majority), by notice given in
writing to the Servicer (and to the Trust Collateral Agent if given by the
Insurer or the Noteholders) or by non-extension of the term of the Servicer as
referred to in Section 4.14 may terminate all of the rights and obligations of
the Servicer under this Agreement. On or after the receipt by the Servicer of
such written notice or upon termination of the term of the Servicer, all
authority, power, obligations and responsibilities of the Servicer under this
Agreement, whether with respect to the Notes, the Certificates or the Other
Conveyed Property or otherwise, automatically shall pass to, be vested in and
become obligations and responsibilities of the Backup Servicer (or such other
successor Servicer appointed by the Controlling Party); provided, however, that
                                                        --------  -------
the successor Servicer shall have no

                                       65
<PAGE>

liability with respect to any obligation which was required to be performed by
the terminated Servicer prior to the date that the successor Servicer becomes
the Servicer or any claim of a third party based on any alleged action or
inaction of the terminated Servicer. The successor Servicer is authorized and
empowered by this Agreement to execute and deliver, on behalf of the terminated
Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement of the Receivables and the Other Conveyed
Property and related documents to show the Trust as lienholder or secured party
on the related Lien Certificates, or otherwise. The terminated Servicer agrees
to cooperate with the successor Servicer in effecting the termination of the
responsibilities and rights of the terminated Servicer under this Agreement,
including, without limitation, the transfer to the successor Servicer for
administration by it of all cash amounts that shall at the time be held by the
terminated Servicer for deposit, or have been deposited by the terminated
Servicer, in the Collection Account or thereafter received with respect to the
Receivables and the delivery to the successor Servicer of all Receivable Files,
Monthly Records and Collection Records and a computer tape in readable form as
of the most recent Business Day containing all information necessary to enable
the successor Servicer or a successor Servicer to service the Receivables and
the Other Conveyed Property. If requested by the Controlling Party, the
successor Servicer shall terminate the Lockbox Agreement and direct the Obligors
to make all payments under the Receivables directly to the successor Servicer
(in which event the successor Servicer shall process such payments in accordance
with Section 4.2(e)), or to a lockbox established by the successor Servicer at
the direction of the Controlling Party, at the successor Servicer's expense. The
terminated Servicer shall grant the Trust Collateral Agent, the successor
Servicer and the Controlling Party reasonable access to the terminated
Servicer's premises at the terminated Servicer's expense.

     SECTION 9.3.   Appointment of Successor.
                    -------------------------

     (a)  On and after the time the Servicer receives a notice of termination
pursuant to Section 9.2, upon non-extension of the servicing term as referred to
in Section 4.14, or upon the resignation of the Servicer pursuant to Section
8.6, the Backup Servicer (unless the Insurer shall have exercised its option
pursuant to Section 9.3(b) to appoint an alternate successor Servicer) shall be
the successor in all respects to the Servicer in its capacity as servicer under
this Agreement and the transactions set forth or provided for in this Agreement,
and shall be subject to all the rights, responsibilities, restrictions, duties,
liabilities and termination provisions relating thereto placed on the Servicer
by the terms and provisions of this Agreement except as otherwise stated herein.
The Trust Collateral Agent and such successor shall take such action, consistent
with this Agreement, as shall be necessary to effectuate any such succession. If
a successor Servicer is acting as Servicer hereunder, it shall be subject to
term-to-term servicing as referred to in Section 4.14 and to termination under
Section 9.2 upon the occurrence of any Servicer Termination Event applicable to
it as Servicer.

     (b)  The Controlling Party may exercise at any time its right to appoint as
Backup Servicer or as successor to the Servicer a Person other than the Person
serving as Backup Servicer at the time, and (without limiting its obligations
under the Note Policy) shall have no liability to the Trust Collateral Agent,
AmeriCredit, CP Funding, the Seller, the Person then serving as Backup Servicer,
any Noteholders or any other Person if it does so. Notwithstanding

                                       66
<PAGE>

the above, if the Backup Servicer shall be legally unable or unwilling to act as
Servicer, and an Insurer Default shall have occurred and be continuing, the
Backup Servicer, the Trust Collateral Agent or a Note Majority may petition a
court of competent jurisdiction to appoint any Eligible Servicer as the
successor to the Servicer. Pending appointment pursuant to the preceding
sentence, the Backup Servicer shall act as successor Servicer unless it is
legally unable to do so, in which event the outgoing Servicer shall continue to
act as Servicer until a successor has been appointed and accepted such
appointment. Subject to Section 8.6, no provision of this Agreement shall be
construed as relieving the Backup Servicer of its obligation to succeed as
successor Servicer upon the termination of the Servicer pursuant to Section 9.2,
the resignation of the Servicer pursuant to Section 8.6 or the non-extension of
the servicing term of the Servicer, as referred to in Section 4.14. If upon the
termination of the Servicer pursuant to Section 9.2 or the resignation of the
Servicer pursuant to Section 8.6, the Controlling Party appoints a successor
Servicer other than the Backup Servicer, the Backup Servicer shall not be
relieved of its duties as Backup Servicer hereunder.

     (c)  Any successor Servicer shall be entitled to such compensation (whether
payable out of the Collection Account or otherwise) as the Servicer would have
been entitled to under this Agreement if the Servicer had not resigned or been
terminated hereunder. If any successor Servicer is appointed as a result of the
Backup Servicer's refusal (in breach of the terms of this Agreement) to act as
Servicer although it is legally able to do so, the Insurer and such successor
Servicer may agree on reasonable additional compensation to be paid to such
successor Servicer by the Backup Servicer, which additional compensation shall
be paid by such breaching Backup Servicer in its individual capacity and solely
out of its own funds provided, however, it being understood and agreed that the
                     --------  -------
Insurer shall give prior notice to the Backup Servicer with respect to the
appointment of such successor and the payment of additional compensation, if
any. If any successor Servicer is appointed for any reason other than the Backup
Servicer's refusal to act as Servicer although legally able to do so, the
Insurer and such successor Servicer may agree on additional compensation to be
paid to such successor Servicer, which additional compensation shall be payable
as provided in the Spread Account Agreement and shall in no event exceed
$150,000. In addition, any successor Servicer shall be entitled, as provided in
the Spread Account Agreement, to reasonable transition expenses incurred in
acting as successor Servicer.

     SECTION 9.4.   Notification to Noteholders.  Upon any termination of, or
                    ---------------------------
appointment of a successor to, the Servicer, the Trust Collateral Agent shall
give prompt written notice thereof to each Noteholder and to the Rating
Agencies.

     SECTION 9.5.   Waiver of Past Defaults. So long as no Insurer Default shall
                    -----------------------
have occurred and be continuing, the Insurer (or, if an Insurer Default shall
have occurred and be continuing, the Note Majority) may, on behalf of all
Noteholders, waive any default by the Servicer in the performance of its
obligations hereunder and its consequences. Upon any such waiver of a past
default, such default shall cease to exist, and any Servicer Termination Event
arising therefrom shall be deemed to have been remedied for every purpose of
this Agreement. No such waiver shall extend to any subsequent or other default
or impair any right consequent thereto.

would result in a claim on the Note Policy or would result in any amount owing
to the Insurer under the Insurance Agreement remaining unpaid); provided,

the Trust Agreement, the Servicer shall instruct the Trust Collateral Agent to

payment in full of the principal of and interest on the Notes, the
Certificateholders will succeed to the rights of the Noteholders hereunder and
the Owner Trustee will succeed to the rights of, and assume the obligations of,
the Trust Collateral Agent pursuant to this Agreement.

         REPRESENTATIONS AND WARRANTIES OF THE SELLER AND THE SERVICER
         -------------------------------------------------------------

          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

Dealer had all necessary licenses and permits to originate Receivables in 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.  Fraud or Misrepresentation. Each Receivable was originated by a
              --------------------------
Dealer and was sold by the Dealer to AmeriCredit and by AmeriCredit or CP
Funding to the Seller 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 State
              -----------

          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

                                       1
<PAGE>

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.   Schedule of Receivables. The information set forth in the
               -----------------------
Schedule 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, the Seller 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 the Seller by the Servicer and resold by the
Seller to the Trust in accordance with the terms of the Sale and Servicing
Agreement.

          10.  Computer Tape. The Computer Tape made available by the Seller 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 the Seller 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 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.

                                       2
<PAGE>

          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 Securities.

          17.  Good Title. Immediately prior to the conveyance of the
               ----------
Receivables to the Trust pursuant to this Agreement or Subsequent Transfer
Agreement, as applicable, the Seller 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 the Seller, the Trust 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.
The Seller 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 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 the Seller 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 the Seller 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, the Seller has received written evidence from the related
Dealer that such Lien Certificate showing the Seller as first lienholder has
been applied for and the Seller's security interest has been validly assigned by
the Seller to the Trust pursuant to this Agreement. Immediately after the sale,
transfer and assignment thereof by the Seller to the Trust, each Receivable will
be secured by an enforceable and perfected first priority security interest in
the Financed Vehicle in favor of the Trustee 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 the Trust 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. The Seller 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.

                                       3
<PAGE>

          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 Schedule 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.

                       SERVICING POLICIES AND PROCEDURES
                       ---------------------------------

               Note:  Applicable Time Periods Will Vary by State

Compliance with state collection laws is required of all AmeriCredit Collection
Personnel.  Additionally, AmeriCredit has chosen to follow the guidelines of the
Federal Fair Debt Collection Practices Act (FDCPA).

The Collection Process
----------------------

Customer is issued a monthly billing statement 16 to 20 days before payment is
due.

A.   All accounts are issued to the Computer Assisted Collection System (CACS)
     at 5 days delinquent or at such other dates of delinquency as determined by
     historical payment patterns of the account.

B.   Accounts are then segregated into two groups, those less than 60 days
     delinquent and those over 60 days delinquent.

C.   Accounts less than 60 days delinquent are further segregated into accounts
     that have good residential and business phone numbers and those that do
     not.

D.   For those that have good phone numbers, they are assigned to the Davox
     Group.

E.   For those without good phone numbers, they are assigned to the front-end
     collector.

F.   In both groups, all reasonable collection efforts are made to avoid the
     account rolling over 30 days delinquent, including the use of collection
     letters. Collection letters may be utilized between 15 and 25 days
     delinquent.

G.   At the time the account reaches 31 days delinquent, the collector
     identifies the necessity of any default notification required by state law.

H.   Once the account exceeds 60 days in delinquency, it is assigned to a hard-
     core collector. The hard-core collector then continues the collection
     effort. If the account cannot be resolved through normal collection
     efforts, i.e., satisfactory payment arrangements, then the account may be
     submitted for repossession approval, either voluntary or by an approved
     outside contractor or if necessary for sequestration approval. All
     repossessions and sequestrations must be approved by an Officer.

I.   CACS allows the individual collector to accurately document and update each
     account pertaining to telephone calls and correspondence created as a
     result of contact with the customer.

                                       1

Repossessions
-------------

If repossession of the collateral occurs, whether voluntary or involuntary, the
following steps are taken:

A.   Notification of repossession to proper authorities when necessary.

B.   Inventory of all personal property is taken and a condition report is done
     on the vehicle.

C.   Written notification, as required by state law, to customer(s) concerning
     their rights of redemption or reinstatement along with information on how
     to obtain any personal property that was in the vehicle at the time of
     repossession.

D.   Written request to the originating dealer for all refunds due for dealer
     adds.

E.   Collateral disposition through public or private sale, (dictated by state
     law), in a commercially reasonable manner, whenever possible through a
     Manheim or Adessa Auto Auction.

F.   After the collateral is liquidated, the debtor(s) is notified in writing of
     the deficiency balance owed, if any.

Use of Due Date Changes
-----------------------

Due dates may be changed subject to the following conditions:

A.   The account is contractually current or will be brought current with the
     due date change.

B.   Due date changes cannot exceed the total of 15 days over the life of the
     contract.

C.   The first installment payment has been paid in full.

D.   Only one date change in a twelve month period.

E.   Any exceptions to the above stated policy must be approved by an Officer.

Use of Payment Deferments
-------------------------

A payment deferral is offered to customers who have the desire and capacity to
make future payments but who have encountered temporary financial difficulties,
with management approval.

A.   Minimum of six payments have been made on the account and a minimum of nine
     made since the last deferment, if any.

B.   The account will be brought current with the deferment, but not paid ahead,
     without management approval

C.   A deferment fee is collected on all transactions.

                                       2
<PAGE>

D.   No more than eight total payments may be deferred over the life of the
     loan, without management approval.

E.   Any exceptions to the above stated policy must be approved by an Officer.

Charge-Offs
-----------

A.   It is AmeriCredit's policy that any account that is not successfully
     recovered by 120 days delinquent is submitted to an Officer for approval
