          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

                                       11

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.

          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 $182,000,000, Class A-2 Notes in the

principal amount of $572,000,000 and Class A-4 Notes in the aggregate principal
amount of $233,000,000. 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

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

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

          (c)  no provision of this Agreement or any Basic Document shall
require the Owner Trustee to expend or risk funds or otherwise incur any

or under any Basic Document if the Owner Trustee shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured or provided to it;

indebtedness evidenced by or arising under any of the Basic Documents, including

Trustee, Trust Collateral Agent, the Collateral Agent, any Noteholder or to any
Certificateholder, other than as expressly provided for herein and in the Basic
Documents;

          (g)  the Owner Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Agreement, or to institute, conduct or
defend any litigation under this Agreement or otherwise or in relation to this
Agreement or any Basic Document, at the request, order or direction of the
Instructing Party or the Certificateholder, unless such Instructing Party or
Certificateholder has offered to the Owner Trustee security or indemnity
satisfactory to it against the costs, expenses and liabilities that may be
incurred by the Owner Trustee therein or thereby. The right of the Owner Trustee
to perform any discretionary act enumerated in this Agreement or in any Basic
Document shall not be construed as a duty, and the Owner Trustee shall not be
answerable for other than its negligence, bad faith or willful misconduct in the
performance of any such act.

          SECTION 6.2.  Furnishing of Documents. The Owner Trustee shall furnish

hereby represents and warrants to the Depositor, the Holder and the Security
Insurer (which shall have relied on such representations and warranties in
issuing the Note Policy), that:

          (a)  It is a Delaware banking corporation, duly organized and validly
existing in good standing under the laws of the State of Delaware. It has all
requisite corporate power and authority to execute, deliver and perform its
obligations under this Agreement.

          (b)  It has taken all corporate action necessary to authorize the
execution and delivery by it of this Agreement, and this Agreement will be
executed and delivered by one of its officers who is duly authorized to execute
and deliver this Agreement on its behalf.

          (c)  Neither the execution nor the delivery by it of this Agreement,
nor the consummation by it of the transactions contemplated hereby nor
compliance by it with any of the terms or provisions hereof will contravene any
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
by which any of its properties may be bound.

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

          (a)  The Owner Trustee shall incur no liability to anyone in acting
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
of which is not specifically prescribed herein, the Owner Trustee may for all
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.
The Owner Trustee shall not be liable for anything done, suffered or omitted in
good faith by it in accordance with the written opinion or advice of any such
counsel, accountants or other such persons and according to such opinion not
contrary to this Agreement or any Basic Document.

          SECTION 6.5.  Not Acting in Individual Capacity.  Except as provided

in this Article VI, in accepting the trust hereby created Bankers Trust
(Delaware) acts solely as Owner Trustee hereunder and not in its individual

the transactions contemplated by this Agreement or any Basic Document shall look
only to the Owner Trust Estate for payment or satisfaction thereof.

          SECTION 6.6.  Owner Trustee Not Liable for Certificate or Receivables.
                        -------------------------------------------------------
The recitals contained herein and in the Certificate (other than the signature

the statements of the Depositor 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 Agreement, of any Basic Document or of the
Certificate (other than the signature and countersignature of the Owner Trustee
on the Certificate) or the Notes, or of any Receivable or related documents. The
Owner Trustee shall at no time have any responsibility or liability for or with
respect to the legality, validity and enforceability of any Receivable, or the
perfection and priority of any security interest created by any Receivable in
any Financed Vehicle or the maintenance of any such perfection and priority, or
for or with respect to the sufficiency of the Owner Trust Estate or its ability
to generate the payments to be distributed to Certificateholder under this
Agreement or the Noteholders under the Indenture, including, without limitation:
the existence, condition and ownership of any Financed Vehicle; the existence
and enforceability of any insurance thereon; the existence and contents of any
Receivable on any computer or other record thereof; the validity of the
assignment of any Receivable to the Trust or of any intervening assignment; the
completeness of any Receivable; the performance or enforcement of any
Receivable; the compliance by the Depositor, the Servicer or any other Person
with any warranty or representation made under any Basic Document or in any
related document or the accuracy of any such warranty or representation or any
action of the Trustee or the Servicer or any subservicer taken in the name of
the Owner Trustee.

          SECTION 6.7.  Owner Trustee May Own Notes.  The Owner Trustee in its
                        ---------------------------
individual or any other capacity may become the owner or pledgee of the Notes
and may deal with the Depositor, the Trustee and the Servicer in banking
transactions with the same rights as it would have if it were not Owner Trustee.

          SECTION 6.8.  Payments from Owner Trust Estate.  All payments to be
                        --------------------------------
made by the Owner Trustee under this Agreement or any of the Basic Documents to
which 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
<PAGE>

approval or authorization or order of or the giving of notice to, or the
registration with or the taking of any other action in respect of, any state or
other governmental authority or agency of any jurisdiction other than the State
of Delaware; (ii) result in any fee, tax or other governmental charge under the
laws of the State of Delaware becoming payable by Bankers Trust (Delaware) (or
any successor thereto); or (iii) subject Bankers Trust (Delaware) (or any
successor thereto) to personal jurisdiction in any jurisdiction other than the
State of Delaware for causes of action arising from acts unrelated to the
consummation of the transactions by Bankers Trust (Delaware) (or any successor
thereto) or the Owner Trustee, as the case may be, contemplated hereby.

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

          SECTION 7.1.  Owner Trustee's Fees and Expenses.  The Owner Trustee
                        ---------------------------------

Trustee, and the Owner Trustee shall be entitled to be reimbursed by the
Depositor for its other reasonable expenses hereunder, including the reasonable

          SECTION 7.2.  Indemnification.  The Depositor shall be liable as
                        ---------------
primary obligor for, and shall indemnify the Owner Trustee and its officers,

losses, damages, taxes, claims, actions and suits, and any and all reasonable
costs, expenses and disbursements (including reasonable legal fees and expenses)
of any kind and nature whatsoever (collectively, "Expenses") which may at any
time be imposed on, incurred by, or asserted against the Owner Trustee or any
Indemnified Party in any way relating to or arising out of this Agreement, the
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
event of any claim, action or proceeding for which indemnity will be sought
pursuant to this Section, the Owner Trustee's choice of legal counsel shall be
subject to the approval of the Depositor which approval shall not be
unreasonably withheld. AmeriCredit Corp. shall be jointly and severally liable
for the indemnification duties and obligations of the Depositor which are
described in this Section 7.2.

          SECTION 7.4.  Non-recourse Obligations.  Notwithstanding anything in
                        ------------------------
this Agreement or any Basic Document, the Owner Trustee agrees in its individual
capacity and in its capacity as Owner Trustee for the Trust that all obligations
of the Trust to the Owner Trustee individually or as Owner Trustee for the Trust

without recourse to the assets of the Holder.

                                 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
such Receivables as provided in the Basic Documents, or (ii) the payment to the
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.

          (b)  Neither the Depositor nor the Certificateholder shall be entitled
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.

                                  ARTICLE X.

Trustee, with the prior written consent of the Security Insurer (so long as an
Insurer Default shall not have occurred and be continuing) and with prior
written notice to the Rating Agencies, without the consent of any of the
Noteholders or the Certificateholder, (i) to cure any ambiguity or defect or
(ii) to correct, supplement or modify any provisions in this Agreement;
provided, however, that such action shall not, as evidenced by an Opinion of
--------  -------
Counsel which may be based upon a certificate of the Servicer, adversely affect
in any material respect the interests of any Noteholder or Certificateholder.

          (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
shall not have occurred and be continuing) by the Depositor and the Owner
Trustee, with prior written notice to the Rating Agencies, to the extent such
amendment materially and adversely affects the interests of the Noteholders,
with the consent of the Noteholders evidencing not less than a majority of the
Outstanding Amount of the Notes, and the consent of the Certificateholder (which
consent of any Holder of a Certificate or Note given pursuant to this Section or
pursuant to any other provision of this Agreement shall be conclusive and
binding on such Holder) for the purpose of adding any provisions to or changing

                           (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.
