identity or corporate structure (within the meaning of Section 9-402(7) of the
UCC as in effect in the State of New York, Delaware and Texas) or relocate its
chief executive office or any office where Records are kept unless it shall
have: (i) given the Collateral Agent at least thirty (30) days' prior notice
thereof and (ii) prepared at the Debtor's expense and delivered to the
Collateral Agent all financing statements, instruments and other documents
necessary to preserve and protect the Collateral or requested by the Collateral
Agent or any Secured Party in connection with such change or relocation. Any
filings under the UCC or otherwise that are occasioned by such change in name or
location shall be made at the expense of the Debtor. On the Initial Funding
Date, the Debtor shall deliver to the Collateral Agent a listing by account
number of the Contracts as of the Initial Funding Date, which listing shall
constitute Schedule A hereto and is hereby incorporated herein by reference. On
each Remittance Date, the Debtor shall deliver to the Collateral Agent an
updated listing by account number of the Contracts as of the last day of such
Settlement Period (giving effect to any releases by the Company pursuant to
Section 2.15 hereof) and such updated list shall thereupon constitute Schedule A
hereto and is hereby incorporated by reference herein.

               (b)  The Collection Agent shall instruct all Obligors to cause
all Collections to be deposited directly with a Lock-Box Bank, acting as agent
for the Collateral Agent, on behalf of the Secured Parties, pursuant to a Lock-
Box Agreement. Amounts received by a Lock-Box Bank in respect of Receivables may
initially be deposited into a Lock-Box Account maintained by the Lock-Box Bank
as agent for the Collateral Agent, on behalf of the Secured Parties, and for
other owners of automobile receivables serviced by the Collection Agent. The
Collection Agent shall be permitted to give instructions to the Lock-Box Banks
for so long as neither a Potential Termination Event nor any Termination Event
has occurred hereunder. The Collection Agent shall not add any bank as a Lock-
Box Bank to those listed on Exhibit A attached hereto unless such bank has
entered into a Lock-Box Agreement. The Collection Agent shall not terminate any
bank as a Lock-Box Bank unless the Collateral Agent shall have received fifteen
(15) days' prior notice of such termination. The Collection Agent shall use its
best efforts to cause the Lock-Box Bank, pursuant to the Lock-Box Agreement, to
deposit all payments on the Receivables in the Lock-Box Account not later than
the Business Day after receipt thereof and, within two (2) Business Days of
receipt of Collections into the Lock-Box Account, the Collection Agent shall
cause such Collections to be remitted into the

receives any Collections, the Debtor, AmeriCredit, AFC III or the Collection
Agent, as applicable, shall immediately, but in any event within two (2)
Business Days of receipt, remit (and shall cause AmeriCredit and AFC III to
remit) such Collections to the Collection Account.

dilutive factor or other adjustment or (y) reduced or canceled as a result of a
setoff or offset in respect of any claim by any Person (whether such claim
arises out of the same or a related transaction or an unrelated transaction),
the Debtor shall be deemed to have received on such day a Collection of such
Receivable in the amount of such reduction or cancellation and the Debtor shall
pay to the Collection Agent an amount equal to such reduction or cancellation
and such amount shall be deposited into the Collection Account and applied by
the Collection Agent as a Collection in accordance with Section 2.3 or 2.4
hereof, as applicable. The Net Investment shall be reduced by the amount of such
payment applied to the reduction of the Net Investment and actually received by
the Agent.

               (b)  If on any day any of the representations or warranties in
Article III was or becomes untrue with respect to a Receivable (whether on or

for the benefit of the Secured Parties, as contemplated hereunder), the Debtor
shall be deemed to have received on such day a Collection of such Receivable in
full and the Debtor shall on such day pay to the Collection Agent an amount
equal to the Outstanding Balance of such Receivable and such amount shall be
deposited into the Collection Account and allocated and applied by the
Collection Agent as a Collection allocable to the Net Investment in accordance
with Section 2.3 or 2.4 hereof, as applicable. The Net Investment shall be
reduced by the amount of such payment applied to the reduction of the Net
Investment and actually received by the Agent.

               (c)  Any payment by an Obligor in respect of any indebtedness
owed by it to the Debtor, AmeriCredit or AFC III shall, except as otherwise
specified by such Obligor or otherwise required by contract or law and unless
otherwise instructed by the Agent, be applied as a Collection of any Receivable
of such Obligor included in the Net Investment (starting with the oldest such
Receivable) to the extent of any amounts then due and payable thereunder before
being applied to any other receivable or other indebtedness of such Obligor.

     SECTION 2.8.   Payments and Computations, Etc. All amounts to be paid or

or otherwise), they shall be paid or deposited in the Agent's account indicated
in Section 9.3 hereof, until otherwise notified by the Agent, the Company or any
other Owners. The Debtor shall, to the extent permitted by law, pay to the
applicable Secured Parties upon demand, interest on all amounts not paid or
deposited when due to the Secured Parties hereunder at a rate equal to 2% per

the basis of a year of 360 days for the actual number of days (including the

amounts payable by the Debtor hereunder shall be binding upon the Debtor absent
manifest error.

interest in and to all funds deposited from time to time in the Collection
Account. The Collection Agent shall remit daily from the Lock-Box Account,
within two (2) Business Days of receipt, to the Collection Account all
Collections received with respect to any Receivables. On each Remittance Date,

shall be distributed hereunder as such. On the date on which the Net Investment
is zero and all Carrying Costs and other Aggregate Unpaids have been paid in

the Debtor.

               (b)  Subject to subsection (d) below, funds on deposit in the
Collection Account shall be invested in Eligible Investments by the Collateral
Agent at the written direction of the Servicer, provided that if such Eligible
Investments are not available or a Termination Event shall have occurred, such

                    ------------------------------
appoint Bank One to act solely on their behalf as Collateral Agent hereunder,
and Bank One hereby accepts such appointment. The Collateral Agent, both prior
to the occurrence of a Termination Event hereunder and after a Termination Event
shall have been cured or waived, shall undertake to perform such duties and only
such duties as are specifically set forth in this Agreement. The Collateral
Agent shall at all times after the occurrence of a Termination Event which has
not been cured or waived exercise such of the rights and powers vested in it
pursuant to this Agreement using the same degree of care and skill as a prudent
person would exercise or use in the conduct of his or her own affairs.

          All Collections received by the Collateral Agent from the Collection
Agent or otherwise will, pending remittance to the Secured Party entitled
thereto, be held in trust by the Collateral Agent for the benefit of the Secured

(i) securities transaction charges not waived due to the Collateral Agent's
receipt of a payment from a financial institution with respect to certain
Eligible Investments and (ii) the compensation and expenses of its counsel and
agents) pursuant to a separate letter agreement between the Collateral Agent and
the Debtor. All such amounts shall be payable from funds available therefor in
accordance with Section 2.3(a)(iv) hereof. Notwithstanding any other provisions
in this Agreement, the Collateral Agent shall not be liable for any liabilities,
costs or expenses of the Debtor arising under any tax law, including without

tax imposed on or measured by income (or any interest or penalties with respect
thereto or from a failure to comply therewith).

severally, indemnify the Collateral Agent, its officers, directors, employees
and agents for, and hold it harmless against any loss, liability or expense
incurred without willful misconduct, gross negligence or bad faith on its part,
arising out of or in connection with (i) the acceptance or administration of
this Agreement, including the costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of its
powers or duties under this Agreement and (ii) the negligence, willful
misconduct or bad faith of the Debtor in the performance of its duties
hereunder. All such amounts shall be payable in accordance with Section
2.3(a)(iv) hereof. The provisions of this Section 7.2 shall survive the
termination of this Agreement.

     SECTION 7.3.   [Intentionally Omitted].
                    -----------------------

     SECTION 7.4.   Liability of the Collateral Agent.
                    ---------------------------------

               (a)  The Collateral Agent shall be liable in accordance herewith
only to the extent of the obligations specifically undertaken by the Collateral
Agent in such capacity herein. No implied covenants or obligations shall be read
into this Agreement against the Collateral Agent and, in the absence of bad
faith on the part of the Collateral Agent, the Collateral Agent may conclusively
rely on the truth of the statements and the correctness of the opinions
expressed in any certificates or opinions furnished to the Collateral Agent and
conforming to the requirements of this Agreement.

               (b)  The Collateral Agent shall not be liable for an error of
judgment made in good faith by an authorized officer, unless it shall be
conclusively proved in a judicial proceeding that the Collateral Agent shall
have been negligent in ascertaining the pertinent facts of which the Collateral
Agent is required by the terms of this Agreement or any other Transaction
Documents to make itself aware.

               (c)  The Collateral Agent shall not be liable with respect to any
action taken, suffered or omitted to be taken in good faith in accordance with
this Agreement or at the

                                       48
<PAGE>

direction of a Secured Party relating to the exercise of any power conferred
upon the Collateral Agent under this Agreement.

               (d)  The Collateral Agent shall not be charged with knowledge of
any Termination Event unless an authorized officer obtains actual knowledge of
such event or the Collateral Agent receives written notice of such event from
the Debtor, the Company, any other Owner, any other Secured Party or the Agent,
as the case may be.

               (e)  Without limiting the generality of this Section 7.4, the
Collateral Agent shall have no duty (i) to see to any recording, filing or
depositing of this Agreement or any other Transaction Document or any financing
statement or continuation statement evidencing a security interest in the
Receivables or the Financed Vehicles, or to see to the maintenance of any such
recording or filing or depositing or to any recording, refiling or redepositing
of any thereof, (ii) to see to any insurance of the Financed Vehicles or
Obligors or to effect or maintain any such insurance, (iii) to see to the
payment or discharge of any tax, assessment or other governmental charge or any
Lien or encumbrance of any kind owing with respect to, assessed or levied
against, any part of the Receivables, (iv) to confirm or verify the contents of
any reports or certificates of the Collection Agent or the Debtor delivered to
the Collateral Agent pursuant to this Agreement believed by the Collateral Agent
to be genuine and to have been signed or presented by the proper party or
parties or (v) to inspect the Financed Vehicles at any time or ascertain or
inquire as to the performance or observance of any of the Debtor's or the
Collection Agent's representations, warranties or covenants or the Collection
Agent's duties and obligations as Collection Agent and as custodian of books,
records, files and computer records relating to the Receivables.

               (f)  The Collateral Agent shall not be required to expend or risk
its own funds or otherwise incur financial liability in the performance of any
of its duties hereunder, or in the exercise of any of its rights or powers, if
there shall be reasonable ground for believing that the repayment of such funds
or adequate indemnity against such risk or liability shall not be reasonably
assured to it, and none of the provisions contained in this Agreement shall in
any event require the Collateral Agent to perform, or be responsible for the
manner of performance of, any of the obligations of the Collection Agent under
this Agreement.

               (g)  The Collateral Agent may rely and shall be protected in
acting or refraining from acting upon any resolution, officer's certificate, any
Servicer's Certificate, certificate of auditors, or any other certificate,
statement, instrument, opinion, report, notice, request, consent, order,
appraisal, bond or other paper or document reasonably believed by it to be
genuine and to have been signed or presented by the proper party or parties.

               (h)  The Collateral Agent may consult with counsel and any
opinion of such counsel shall be full and complete authorization and protection
in respect of any action taken or suffered or omitted by it under this Agreement
in good faith and in accordance with such opinion of counsel.

               (i)  The Collateral Agent 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 in relation
to this Agreement, at the request, order or direction

                                       49
<PAGE>

of the Agent pursuant to the provisions of this Agreement, unless the Agent
shall have offered to the Collateral Agent reasonable security or indemnity
against the costs, expenses and liabilities that may be incurred therein or
thereby; nothing contained in this Agreement, however, shall relieve the
Collateral Agent of its obligations, upon the occurrence of a Termination Event
(that shall not have been cured or waived), to exercise such of the rights and
powers vested in it by this Agreement, and to use the same degree of care and
skill in their exercise as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

               (j)  The Collateral Agent shall not be liable for any action
taken, suffered or omitted by it in good faith and believed by it to be
authorized or within the discretion or rights or powers conferred upon it by
this Agreement.

               (k)  Prior to the occurrence of a Termination Event and before
the Collateral Agent has received notice of such Termination Event and after the
waiver of any Termination Event that may have occurred, the Collateral Agent
shall not be bound to make any investigation into the facts of matters stated in
any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, bond or other paper or document, unless
requested in writing so to do by a Secured Party; provided, however, that if the
                                                  --------  -------
payment within a reasonable time to the Collateral Agent of the costs, expenses
or liabilities likely to be incurred by it in the making of such investigation
shall be, in the opinion of the Collateral Agent, not reasonably assured by the
Debtor, the Collateral Agent may require reasonable indemnity against such cost,
expense or liability as a condition to so proceeding. The reasonable expense of
every such examination shall be paid by the Debtor or, if paid by the Collateral
Agent, shall be reimbursed by the Debtor upon demand.

               (l)  The Collateral Agent may execute any of the trusts or powers
hereunder or perform any duties under this Agreement either directly or by or
through agents or attorneys or a custodian. The Collateral Agent shall not be
responsible for any misconduct or negligence of any such Agent or custodian
appointed with due care by it hereunder.

be under any liability to the Agent, any Secured Party or any other Person
hereunder or pursuant to any document delivered hereunder, it being expressly
understood that all such liability is expressly waived and released as a
condition of, and as consideration for, the execution of this Agreement;
provided, however, that this provision shall not protect the directors,
--------  -------
officers, employees and agents of the Collateral Agent against any liability
which would otherwise be imposed by reason of willful misfeasance, bad faith or
gross negligence in the performance of duties or by reason of reckless disregard
of obligations and duties hereunder.  Except as provided in Section 7.4 hereof,
the Collateral Agent shall not be under any liability to any Secured Party or
any other Person for any action taken or for refraining from the taking of any
action in its capacity as Collateral Agent pursuant to this Agreement whether
arising from express or implied duties under this Agreement; provided, however,
                                                             --------  -------
that this provision shall not protect the Collateral Agent against any liability
which would otherwise be imposed by reason of willful misfeasance, bad faith or
gross negligence in the performance of duties or by reason of reckless disregard
of obligations and

                                       50
<PAGE>

duties hereunder. The Collateral Agent may rely in good faith on any document of
any kind prima facie properly executed and submitted by any Person respecting
         ----- -----
any matters arising hereunder. The Collateral Agent shall not be under any
obligation to appear in, prosecute or defend any legal action which is not
incidental to its duties to administer the Collections and the Collection
Account in accordance with this Agreement which in its reasonable opinion may
involve it in any expense or liability.

entitlements related thereto) shall be governed by the laws of the State of New
York.

cash and all other Aggregate Unpaids have been paid in full in cash; provided,
                                                                     --------
however, that (i) the rights and remedies of the Collateral Agent, the

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

               (a)   No failure or delay on the part of the Collateral Agent,
the Administrative Agent, the Agent or any of the Secured Parties in exercising
any power, right or remedy under this Agreement shall operate as a waiver
thereof, nor shall any single or partial exercise of any such power, right or
remedy preclude any other further exercise thereof or the exercise of any other
power, right or remedy. The rights and remedies herein provided shall be
cumulative and nonexclusive of any rights or remedies provided by law.

               (b)   Any provision of this Agreement or any of the Transaction
Documents may be amended or waived if, but only if, such amendment is in writing
and is signed by the Debtor, the Collection Agent and the Company and the

by the Collateral Agent).

     SECTION 9.3.    Notices.  Except as provided below, all communications and
                     -------
notices provided for hereunder shall be in writing (including bank wire, telex,
telecopy or electronic facsimile transmission or similar writing) and shall be
given to the other party at its address or telecopy number set forth below or at
such other address or telecopy number as such party may hereafter specify for
the purposes of notice to such party. Each such notice or other communication
shall be effective (i) if given by telecopy, when such telecopy is transmitted
to the telecopy number specified in this Section 9.3 and confirmation is
received, (ii) if given by mail three (3) Business Days following such posting,
if postage prepaid, or if sent via U.S. certified or registered mail, (iii) if
given by overnight courier, one (1) Business Day after deposit thereof with a
national overnight courier service, or (iv) if given by any other means, when

Section 9.3 to the contrary notwithstanding, the Debtor hereby authorizes the
Company to effect Fundings, funding period and interest rate selections based on
telephonic notices made by any Person which the Company in good faith believes
to be acting on behalf of the Debtor. The Debtor agrees to deliver promptly to
the Company a written confirmation of each telephonic notice signed by an
authorized officer of the Debtor. However, the absence of such confirmation
shall not affect the validity of such notice. If the written confirmation
differs in any material respect from the action taken by the Company, the
records of the Company shall govern absent manifest error.

Debtor, AmeriCredit, AFC III or the Collection Agent may assign any of its
rights or delegate any of its duties hereunder or under the Master Receivables

disclosure shall occur without the prior review by the Administrative Agent of

Purchase Agreement with respect to such Receivable or Contract. The Debtor
agrees that neither it nor the Collection Agent shall give any consent or waiver
required or permitted to be given under the Master Receivables Purchase
Agreement with respect to the Receivables or the Contracts without the prior
consent of the Agent, the Collateral Agent and the Administrative Agent.

                (b)   Each of the parties hereto agrees to treat the

contrary notwithstanding, the Debtor shall (i) perform all of its obligations
under the Contracts related to the Receivables to the same extent as if
interests in such Receivables had not been pledged hereunder and the exercise by
the Collateral Agent or any Secured Party of their rights hereunder shall not
relieve the Debtor from such obligations and (ii) pay when due any taxes,
including without limitation, any sales taxes payable in connection with the
Receivables and their creation and satisfaction. Neither the Collateral Agent
nor any Secured Party shall have any obligation or liability with respect to any
Receivable or related Contracts, nor shall any of them be obligated to perform
any of the obligations of the Debtor thereunder.

     SECTION 9.13.    Headings.  Section headings used in this Agreement are for
                      --------

individually or personally but solely as Trustee of the Debtor, in the exercise
of the powers and authority conferred and vested in it, (b) each of the

involuntary, through the exercise of any right of setoff, or otherwise) on
account of any interest in the Note owned by it in excess of its ratable share
of payments on account of any interest in the Note obtained by such Owner
entitled thereto, such Recipient shall forthwith purchase from the Company
and/or the other Owners entitled to a share of such amount participations in the
percentage interests owned by such Persons as shall be necessary to cause such
Recipient to share the excess payment ratably with each such other Person
entitled thereto; provided, however, that if all or any portion of such excess
                  --------  -------
payment is thereafter recovered from such Recipient, such purchase from each
such other Person shall be rescinded and each such other Person shall repay to
the Recipient the purchase price paid by such Recipient for such participation
to the extent of such recovery, together with an amount equal to such other
Person's ratable share (according to the proportion of (a) the amount of such
other Person's required payment to (b) the total amount so recovered from the
Recipient) of any interest or other amount paid or payable by the Recipient in
respect of the total amount so recovered.

Potential Termination Event to set-off, appropriate and apply (without
presentment, demand, protest or other notice which are hereby expressly waived)
any deposits and any other indebtedness held or owing by the Agent, the Company

     Section 2.5. Selection of Funding Periods and Interest Rates.
                  -----------------------------------------------

                  (a)  Prior to the Termination Date. At all times hereafter,
but prior to the Termination Date and with respect to the Transferred Interest
held by the Agent on behalf of the Company, the Issuer may, subject to the
Company's approval and the limitations described below, request funding periods
and allocate a portion of the Net Investment to each selected funding period, so
that the aggregate amounts allocated to outstanding funding periods at all times
shall equal the Net Investment held on behalf of the Company. The Issuer shall
give the Company irrevocable notice by telephone of the requested funding
period(s) at least one (1) Business Day prior by 12:00 p.m. (New York time) to
the requested Funding Date or the expiration of any then existing funding
period; provided, however, that the Company may select, in its sole discretion,
        --------  -------
any such funding period if (i) the Issuer fails to provide such notice on a
timely basis or (ii) the Company determines, in its sole discretion, that the
funding period requested by the Issuer is unavailable or for any reason
commercially undesirable to any party. The Company confirms that it is its
intention to allocate all or substantially all of the Net Investment held on
behalf of it to one or more funding periods with respect to which the interest
rate applicable thereto is calculated by reference to the CP Rate; provided that
the Company may determine, from time to time, in its sole discretion (whether as
a result of a CP Disruption Event or otherwise), that funding such Net
Investment by means of the issuance of Commercial Paper is not possible or is
not desirable for any reason. Upon such determination, Discount shall be
calculated at the Eurodollar Rate. If the Liquidity Provider acquires from the
Company a Purchased Interest pursuant to the terms of the Liquidity Provider
Agreement, Barclays, on behalf of the Liquidity Provider, may exercise the right
of selection granted to the Company hereby. The initial funding period
applicable to any such Purchased Interest shall be a period of not greater than
14 days and Discount with respect thereto shall be calculated by reference to
the Base Rate. Thereafter, provided that the Termination Date caused by a
Termination Event shall not have occurred, Discount shall be calculated by
reference to the Eurodollar Rate and, if such rate is not available, the Base
Rate. In the case of any funding period outstanding upon the occurrence of the
Termination Date, such funding period shall end on the date of such occurrence.

                  (b)  After the Termination Date. At all times on and after the
                       --------------------------
Termination Date, with respect to any portion of the Transferred Interest which
shall be held by the Agent on behalf of the Company, the Agent shall select all
funding periods. At all times after the Termination Date but prior to the
occurrence of a Termination Event, Discount shall be calculated by reference to
the CP Rate; provided that the Company may determine, from time to time, in its
sole discretion (whether as a result of a CP Disruption Event or otherwise),
that funding such Net Investment by means of the issuance of Commercial Paper is
not possible or is not desirable for any reason. Upon such determination,
Discount shall be calculated at the Eurodollar Rate. If the Liquidity Provider
acquires from the Company a Purchased Interest pursuant to the terms of the
Liquidity Provider Agreement, Barclays, on behalf of the Liquidity Provider, may
exercise the right of selection granted to the Company hereby. The initial
funding period applicable to any such Purchased Interest shall be a period of
not greater than 14 days and Discount with respect thereto shall be calculated
by reference to the Base Rate. Thereafter, provided that a Termination Event
                                           --------
shall not have occurred, Discount shall be calculated by reference to the
Eurodollar Rate and, if such rate is not available, the Base Rate. After the
occurrence of a Termination Event, Discount in respect of any Transferred
Interest held by

                                       8
<PAGE>

the Company or any Purchased Interest held by a Liquidity Provider shall be
determined as set forth in Section 6.2 of the Security Agreement.

                  (c)  Eurodollar Rate Protection; Illegality.
                       --------------------------------------

                       (i)    If the Agent is unable to obtain on a timely basis
the information necessary to determine the Eurodollar Rate for any proposed
funding period, then

                              (1)  the Agent shall forthwith notify the Company
or the other Owners, as applicable and the Issuer that the Eurodollar Rate
cannot be determined for such funding period, and

                              (2)  while such circumstances exist, neither the
Company, the other Owners nor the Agent shall allocate the Net Investment of any
additional advances during such period or reallocate the Net Investment
allocated to any then existing funding period ending during such period, to a
funding period with respect to which Discount is calculated by reference to the
Eurodollar Rate.

                       (ii)   If, with respect to any outstanding funding
period, the Company or any of the other Owners on behalf of which the Agent
holds any Transferred Interest therein notifies the Agent that it is unable to
obtain matching deposits in the London interbank market to fund any advance or
to maintain such Transferred Interest or that the Eurodollar Rate applicable to
such Transferred Interest will not adequately reflect the cost to the Person of
funding or maintaining its respective Transferred Interest for such funding
period then the Agent shall forthwith so notify the Issuer, whereupon neither
the Agent nor the Company or the other Owners, as applicable, shall, while such
circumstances exist, allocate any Net Investment of any additional Transferred
Interest purchased during such period or reallocate the Net Investment allocated
to any funding period ending during such period, to a funding period with
respect to which Discount is calculated by reference to the Eurodollar Rate.

                       (iii)  Notwithstanding any other provision of this
Agreement, if the Company or any of the other Owners, as applicable, shall
notify the Agent that such Person has determined (or has been notified by any
Liquidity Provider) that the introduction of or any change in or in the
interpretation of any law or regulation makes it unlawful (either for the
Company, such other Owner, or such Liquidity Provider, as applicable), or any
central bank or other governmental authority asserts that it is unlawful, for
the Company, such other Owner or such Liquidity Provider, as applicable, to fund
any advance or to maintain the Transferred Interest the Discount with respect to
which is calculated by reference to the Eurodollar Rate, then (x) as of the
effective date of such notice from such Person to the Agent, the obligation or
ability of the Company or such other Owner, as applicable, to fund its purchase
or maintenance of the Transferred Interest at a Discount calculated by reference
to the Eurodollar Rate shall be suspended until such Person notifies the Agent
that the circumstances causing such suspension no longer exist and (y) the Net
Investment of each funding period in which such Person owns an interest shall
either (1) if such Person may lawfully continue to maintain the Transferred
Interest at a Discount calculated by reference to the Eurodollar Rate until the
last day of the applicable funding period, be reallocated on the last day of
such funding period to another funding period in respect of which the Net
Investment allocated thereto accrues Discount determined other than with respect
to the Eurodollar Rate or (2) if such Person shall determine that it

                                       9
<PAGE>

may not lawfully continue to maintain the Transferred Interest at a Discount
calculated by reference to the Eurodollar Rate until the end of the applicable
funding period, such Person's share of the Net Investment allocated to such
funding period shall be deemed to accrue Discount at the Base Rate from the
effective date of such notice until the end of such funding period.

shall not be required to exercise any discretion or take any action, but shall
be required to act or to refrain from acting (and shall be fully protected in so
acting or refraining from acting) upon the instructions of the Majority Owners,
and such instructions shall be binding on the Company and all of the other
Owners; provided, however, that the Agent shall not be required to take any
        --------  -------
action that exposes the Agent to personal liability or that is contrary to any
Transaction Document or applicable law or unless it shall first be indemnified
to its satisfaction by the Owners against any and all liability and expense
which may be incurred by it by reason of taking any such action.

     Section 5.3.  Termination Event or Potential Termination Event. The Agent
                   ------------------------------------------------
shall not be deemed to have knowledge or notice of the occurrence of a Potential
Termination Event or a Termination Event unless the Agent has received written
notice from the Company, any other Owner or the Issuer specifying such Potential
Termination Event or Termination Event and stating that such notice is a "Notice
of Termination Event or Potential Termination Event". In the event that the
Agent receives such a notice of the occurrence of a Potential Termination Event
or Termination Event, the Agent shall give prompt notice thereof to the Company
and the other Owners. The Agent shall (subject to Section 5.2 hereof) take such
action with respect to such Potential Termination Event or Termination Event as
shall reasonably be directed by the Majority Owners, provided that, unless and
                                                     --------
until the Agent shall have received such directions, the Agent may (but shall
not be obligated to) take such action, or refrain from taking such action, with
respect to such Potential Termination Event or Termination Event as it shall
deem advisable in the best interest of the Company.

     Section 5.4.  Agent and Affiliates. To the extent that the Agent or any of
                   --------------------
its affiliates shall become an Owner, the Agent or such affiliate, in such
capacity, shall have the same rights and powers hereunder as any other Owner and
may exercise the same as though it were not acting as the Agent or such
affiliate (as the case may be). Barclays (and any successor acting as Agent) and
its affiliates may (without having to account therefor to the Company or any
other Owner) accept deposits from, lend money to, make investments in, provide
services to, and generally engage in any kind of lending, trust, or other
business with any of the Issuer, AmeriCredit, AFC III and the Collection Agent
or any of their Subsidiaries or affiliates as if it were not acting as Agent,
and Barclays (and any successor acting as Agent or such affiliate) and its
affiliates may accept fees and other consideration from any of the Issuer,
AmeriCredit, AFC III and the Collection Agent or any of their Subsidiaries or
Affiliates for services in connection with this Agreement or otherwise without
having to account for the same to the Company or any other Owner.

     Section 5.5.  Indemnification of the Agent. Each Owner (other than the
                   ----------------------------
Company) agrees to indemnify the Agent (to the extent not reimbursed by the
Issuer), ratably in accordance with its share of the outstanding principal
balance of the Note, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses
(including attorneys' fees), or disbursements of any kind or nature whatsoever
which may be imposed on, incurred by, or asserted against the Agent (including
by the Company or any other Owner) in any way relating to or arising out of this
Agreement or any other Transaction Document or the transactions contemplated
thereby or any action taken or omitted by the Agent under this Agreement or any
other Transaction Document, provided that no Owner shall be liable for any of
                            --------
the foregoing to the extent they arise from the gross negligence or willful
misconduct of the Agent. Without limitation of the foregoing, each Owner
(including the Company but only to the extent that the Company is reimbursed by
the Issuer for such expenses) agrees to reimburse the Agent, ratably in
accordance with its share of the outstanding principal balance of the Note,
promptly upon demand for any out-of-pocket expenses (including attorneys' fees)
incurred by the Agent in connection with the administration, modification,
amendment or enforcement (whether through negotiations, legal proceedings or
otherwise) of, or legal advice in respect of rights or responsibilities under,
this Agreement and the other Transaction Documents, to the extent that such
expenses are incurred in the interests of or otherwise in respect of the Owners
hereunder and/or thereunder and to the extent that the Agent is not reimbursed
for such expenses by the Issuer. The agreements contained in this Section shall
survive payment in full of the Net Investment and all other amounts payable
under this Agreement.

     Section 5.6.  Non-Reliance. Each Owner agrees that it has, independently
                   ------------
and without reliance on the Agent or the Company or any other Owner, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis of the Receivables, the Contracts, the Issuer, AmeriCredit, AFC
III and the Collection Agent and their respective Subsidiaries and decision to
enter into this Agreement and that it will, independently and without reliance
upon the Agent, the Company or any other Owner, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
analysis and decisions in taking or not taking action under the Transaction
Documents. Except for notices, reports, and other documents and information
expressly required to be furnished to the Company and the other Owners by the
Agent hereunder, the Agent shall not have any duty or responsibility to provide
the Company or any other Owner with any credit or other information concerning
the affairs, financial condition, or business of any of the Issuer, AmeriCredit,
AFC III or the Collection Agent or any of their respective Subsidiaries or
affiliates that may come into the possession of the Agent or any of its
affiliates.

     Section 5.7.  Resignation of Agent. The Agent may resign at any time by
                   --------------------
giving notice thereof to the Company, the other Owners and the Issuer. Upon any
such resignation, the Majority Owners shall have the right to appoint a
successor Agent. If no successor Agent shall have been so appointed by the
Majority Owners and shall have accepted such appointment within thirty (30) days
after the retiring Agent's giving of notice of resignation, then the retiring
Agent may, on behalf of the Company and the other Owners, appoint a successor
Agent which shall be a commercial bank organized under the laws of the United
States having combined capital and surplus of at least $100,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor, such successor
shall thereupon succeed to and become vested with all the rights, powers,
discretion, privileges, and duties of the retiring Agent, and the retiring Agent
shall be discharged from its duties and obligations hereunder. After any
retiring Agent's resignation hereunder as Agent, the provisions

                                       19
<PAGE>

of this Article V shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as Agent.

     Section 5.8.  Payments by the Agent. Unless specifically allocated to an
                   ---------------------
Owner pursuant to the terms of this Agreement, all amounts received by the Agent
on behalf of the Owners shall be paid by the Agent to the Owners (at their
respective accounts designated in writing to the Agent) in accordance with their
respective related pro rata interests in the Net Investment on the Business Day
received by the Agent, unless such amounts are received after 12:00 noon on such
Business Day, in which case the Agent shall use its reasonable efforts to pay
such amounts to the Owners on such Business Day, but, in any event, shall pay
such amounts to the Owners in accordance with their respective related pro rata
interests in the Net Investment not later than the following Business Day.

                                   ARTICLE VI

                                 MISCELLANEOUS

     Section 6.1.   Term of Agreement. This Agreement shall terminate on the
                    -----------------
date following the Termination Date upon which the Net Investment has been
reduced to zero, all accrued Discount and Servicing Fees have been indefeasibly
paid in full and all other Aggregate Unpaids have been indefeasibly paid in
full, in each case, in cash; provided, however, that (i) the rights and remedies
                             --------  -------
of the Agent, the Company, the other Owners and the Administrative Agent with
respect to any representation and warranty made or deemed to be made by the
Issuer pursuant to this Agreement, (ii) the indemnification and payment
provisions of Article IV, and (iii) the agreement set forth in Section 6.9
hereof, shall be continuing and shall survive any termination of this Agreement.

     Section 6.2.  Waivers; Amendments.
                   -------------------

                   (a) No failure or delay on the part of the Agent, the
Company, the Administrative Agent or any other Owners in exercising any power,
right or remedy under this Agreement shall operate as a waiver thereof, nor
shall any single or partial exercise of any such power, right or remedy preclude
any other further exercise thereof or the exercise of any other power, right or
remedy. The rights and remedies herein provided shall be cumulative and
nonexclusive of any rights or remedies provided by law.

                   (b) Any provision of this Agreement or any other Transaction
Document may be amended or waived if, but only if, such amendment or waiver is
in writing and is signed by the Issuer, the Collection Agent, the Company and
the Majority Owners (and, if Article V or the rights or duties of the Agent are
affected thereby, by the Agent); provided that no such amendment or waiver
                                 --------
shall, unless signed by each Owner directly affected thereby, (i) increase the
Commitment of the Company, (ii) reduce the Net Investment or rate of interest to
accrue thereon or any fees or other amounts payable hereunder, (iii) postpone
any date fixed for the payment of any scheduled distribution in respect of the
Net Investment or interest with respect thereto or any fees or other amounts
payable hereunder or for termination of the Commitment, (iv) change the
percentage of the Owners which shall be required for the Owners or any of them
to take any action under this section or any other provision of this Agreement,
(v) release all or substantially all of the property with respect to which a
security or ownership interest therein has been granted hereunder or under the
Security Agreement to the Agent or the Owners or (vi) extend or permit the
extension of the Commitment Termination Date. In the event

                                       20
<PAGE>

the Agent requests the Company's or any other Owner's consent pursuant to the
foregoing provisions and the Agent does not receive a consent (either positive
or negative) from the Company or such Owner within 10 Business Days of the
Company's or any other Owner's receipt of such request, then the Company or such
Owner (and its percentage interest hereunder) shall be disregarded in
determining whether the Agent shall have obtained sufficient consent hereunder.

     Section 6.3.   Notices. Except as provided below, all communications and
                    -------
notices provided for hereunder shall be in writing (including telecopy or
electronic facsimile transmission or similar writing) and shall be given to the
other party at its address or telecopy number set forth below or at such other
address or telecopy number as such party may hereafter specify for the purposes
of notice to such party. Each such notice or other communication shall be
effective (i) if given by telecopy, when such telecopy is transmitted to the
telecopy number specified in this Section 6.3 and confirmation is received, (ii)
if given by mail, three (3) Business Days following such posting, if postage
prepaid, or if sent via U.S. certified or registered mail, (iii) if given by
overnight courier, one (1) Business Day after deposit thereof with a national
overnight courier service, or (iv) if given by any other means, when received at
the address specified in this Section 6.3. However, anything in this Section 6.3
to the contrary notwithstanding, the Issuer hereby authorizes the Company to
effect Subsequent Fundings, funding period and interest rate selections based on
telephonic notices made by any Person which the Company in good faith believes
to be acting on behalf of the Issuer. The Issuer agrees to deliver promptly to
the Company a written confirmation of each telephonic notice signed by an
authorized officer of Issuer. However, the absence of such confirmation shall
not affect the validity of such notice. If the written confirmation differs in
any material respect from the action taken by the Company, the records of the
Company shall govern absent manifest error.

or hereafter have to the laying of the venue of any such proceeding brought in
such a court and any claim that any such proceeding brought in such a court has
been brought in an inconvenient forum. Nothing in this Section 6.4 shall affect

               (b) EACH OF THE PARTIES HERETO HEREBY WAIVES ANY RIGHT TO HAVE A

applicable to commercial paper issued by such Conduit Assignee (rather than the
Company), (vii) the defined terms and other terms and provisions of this
Agreement and the other Transaction Documents shall be interpreted in accordance
with the foregoing, and (viii) if requested by the Agent or administrative agent
with respect to the Conduit Assignee, the parties will execute and deliver such
further agreements and documents and take such other actions as the Agent or
such administrative agent may reasonably request to evidence and give effect to
the foregoing.

          (c)  The Issuer hereby agrees and consents to the assignment by the
Company from time to time of all or any part of its rights under, interest in
and title to this Agreement, the other Transaction Documents and the Note to any

other agreements, instruments and documents entered into by it pursuant hereto
or in connection herewith are, in each case, solely the corporate obligations of
the Company, and that no personal liability whatsoever shall attach to or be
incurred by any incorporator, stockholder, affiliate, officer, employee or
director of the Company, as such, or any of them, under or by reason of any of
the obligations, covenants or agreements of the Company contained in this
Agreement or in any other such instruments, documents or agreements, or which
are implied therefrom, and that any and all personal liability of each
incorporator, stockholder, affiliate, officer, employee or director of the
Company, or any of them, for breaches by the Company of any such obligations,
covenants or agreements, which liability may arise either at common law or at
equity, or by statute or constitution, or otherwise, is hereby expressly waived
except to the extent that such personal liability of the Company arises from the
gross negligence or willful misconduct of the Company.  The provisions of this
