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

          (c)  The Servicer is hereby authorized to commence, in it's own name
or in the name of the Trust, a legal proceeding to enforce a Receivable pursuant
to Section 2.3 or to commence or participate in any other legal proceeding
(including, without limitation, a bankruptcy proceeding) relating to or
involving a Receivable, an Obligor or a Financed Vehicle. If the Servicer
commences or participates in such a legal proceeding in its own name, the Trust
shall thereupon be deemed to have automatically assigned such Receivable to the
Servicer solely for purposes of commencing or participating in any such
proceeding as a party or claimant, and the Servicer is authorized and empowered
by the Trust to execute and deliver in the Servicer's name any notices, demands,
claims, complaints, responses, affidavits or other documents or instruments in
connection with any such proceeding. The Collateral Agent shall, in its
reasonable discretion, furnish the Servicer with any limited powers of attorney
and other documents which the Servicer may reasonably request and which the
Servicer deems necessary or appropriate and take any other steps which the
Servicer may deem necessary or appropriate to enable the Servicer to carry out
its servicing and administrative duties under this Agreement.

          Section 2.2.   Collection of Receivable Payments; Modifications of
                         ---------------------------------------------------
Receivables; Lock-Box Agreements.
--------------------------------

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

          (b)  So long as no Servicer Termination Event shall have occurred and
be continuing, and in accordance with the Credit and Collection Policy, the
Servicer may at any time agree to a modification or amendment of a Receivable in
order to (i) change the Obligor's regular due date to a date within the
Settlement Period in which such due date occurs or (ii) re- amortize the
Scheduled Receivables Payments on the Receivable following a partial prepayment

                                       7
<PAGE>

of principal, in accordance with its customary procedures if the Servicer
believes in good faith that such extension, modification or amendment is
necessary to avoid a default on such Receivable, will maximize Collections with
respect to such Receivable, and is otherwise in the best interests of the Trust.

          (c)  So long as no Servicer Termination Event shall have occurred and
be continuing, and in accordance with the Credit and Collection Policy, the
Servicer may grant payment extensions on, or other modifications or amendments
to, a Receivable (in addition to those modifications permitted by Section
2.2(b)) in accordance with its customary procedures if the Servicer believes in
good faith that such extension, modification or amendment is necessary to avoid
a default on such Receivable, will maximize Collections with respect to such
Receivable, and is otherwise in the best interests of the Trust; provided, that
                                                                 --------
any such amendment, modification or extension shall be delivered by the Servicer
to the Custodian promptly after execution thereof.

          The Servicer shall use its best efforts to notify or direct Obligors
to make all payments on the Receivables, whether by check or by direct debit of
the Obligor's bank account, to be made directly to one or more Lock-Box Banks,
acting as agent for the Collateral Agent, on behalf of the Secured Parties
pursuant to a Lock-Box Agreement. The Servicer shall use its best efforts to
notify or direct any Lock-Box Bank to deposit all payments on the Receivables in
the Lock-Box Account no later than the Business Day after receipt, and to cause
all amounts credited to the Lock-Box Account on account of such payments to be
transferred to the Collection Account no later than the second Business Day
after receipt of such payments. The Lock-Box Account shall be a demand deposit
account held by the Lock-Box Bank, or at the request of the Note Insurer, an
Eligible Deposit Account.

          Notwithstanding any Lock-Box Agreement, or any of the provisions of
this Agreement relating to the Lock-Box Agreement, the Servicer shall remain
obligated and liable to the Trust, the Collateral Agent and Secured Parties for
servicing and administering the Receivables and the Other Conveyed Property in
accordance with the provisions of this Agreement without diminution of such
obligation or liability by virtue thereof.

          In the event of a termination of the Servicer, the successor Servicer
shall assume all of the rights and obligations of the outgoing Servicer under
the Lock-Box Agreement subject to the terms hereof. In such event, the successor
Servicer shall be deemed to have assumed all of the outgoing Servicer's interest
therein and to have replaced the outgoing Servicer as a party to each such
Lock-Box Agreement to the same extent as if such Lock-Box Agreement had been
assigned to the successor Servicer, except that the outgoing Servicer shall not
thereby be relieved of any liability or obligations on the part of the outgoing
Servicer to the Lock-Box Bank under such Lock-Box Agreement. The outgoing
Servicer shall, upon request of the Collateral Agent, but at the expense of the
outgoing Servicer, deliver to the successor Servicer all documents and records
relating to each such Lock-Box Agreement and an accounting of amounts collected
and held by the Lock-Box Bank and otherwise use its best efforts to effect the
orderly and efficient transfer of any Lock-Box Agreement to the successor
Servicer. In the event that the Note Insurer elects to change the identity of
the Lock-Box Bank, the outgoing Servicer, at its expense, shall cause the
Lock-Box Bank to deliver, at the direction of the Note Insurer to the Collateral
Agent or a successor Lock-Box Bank, all documents and records relating to the
Receivables and all

                                       8
<PAGE>

amounts held (or thereafter received) by the Lock-Box Bank (together with an
accounting of such amounts) and shall otherwise use its best efforts to effect
the orderly and efficient transfer of the Lock-Box arrangements and the Servicer
shall notify the Obligors to make payments to the Lock-Box established by the
successor.

          (d)  The Servicer shall remit all payments by or on behalf of the
Obligors received directly by the Servicer to the Lock-Box Bank for deposit into
the Lock-Box Account and for transfer to the Collection Account in accordance
with Section 2.2(c) hereof, in either case, without deposit into any intervening
account and as soon as practicable, but in no event later than the Business Day
after receipt thereof.

          Section 2.3.   Realization upon Receivables.
                         ----------------------------

          (a)  Consistent with the standards, policies and procedures required
by this Agreement and the Credit and Collection Policy, the Servicer shall use
its best efforts to repossess (or otherwise comparably convert the ownership of)
and liquidate any Financed Vehicle securing a Receivable with respect to which
the Servicer has determined that payments thereunder are not likely to be
resumed, as soon as is practicable after default on such Receivable but in no
event later than the date on which all or any portion of a Scheduled Receivables
Payment has become 91 days delinquent; provided, however, that the Servicer may
                                       --------  -------
elect not to repossess a Financed Vehicle within such time period if in its good
faith judgment it determines that the proceeds ultimately recoverable with
respect to such Receivable would be increased by forbearance. The Servicer is
authorized to follow such customary practices and procedures as it shall deem
necessary or advisable, consistent with the standard of care required by Section
2.1, which practices and procedures may include reasonable efforts to realize
upon any recourse to Dealers and Third Party Lenders, the sale of the related
Financed Vehicle at public or private sale, the submission of claims under an
Insurance Policy and other actions by the Servicer in order to realize upon such
a Receivable. The foregoing is subject to the provision that, in any case in
which the Financed Vehicle shall have suffered damage, the Servicer shall not
expend funds in connection with any repair or towards the repossession of such
Financed Vehicle unless it shall determine in its reasonable discretion that
such repair and/or repossession shall increase the proceeds of liquidation of
the related Receivable by an amount greater than the amount of such expenses.
All amounts received upon liquidation of a Financed Vehicle shall be remitted by
the Servicer to the Collection Account as soon as practicable, but in no event
later than the Business Day after receipt thereof. The Servicer shall be
entitled to recover all reasonable expenses incurred by it in the course of
repossessing and liquidating a Financed Vehicle into cash proceeds, but only out
of the cash proceeds of such Financed Vehicle, any deficiency obtained from the
Obligor with respect to such Financed Vehicle or any amounts received from the
related Dealer and Third Party Lender with respect to such Financed Vehicle,
which amounts in reimbursement may be retained by the Servicer to the extent of
such expenses. The Servicer shall pay on behalf of the Trust any personal
property taxes assessed on repossessed Financed Vehicles.

          (b)  If the Servicer elects to commence a legal proceeding to enforce
a Dealer Agreement, Third Party Loan Purchase Agreement, Dealer Assignment or
Third Party Lender Assignment, the act of commencement shall be deemed to be an
automatic assignment from the Trust to the Servicer of the rights under such
Dealer Agreement, Third Party Loan Purchase

                                       9
<PAGE>

Agreement, Dealer Assignment and Third Party Lender Assignment for purposes of
collection only. If, however, in any enforcement suit or legal proceeding it is
held that the Servicer may not enforce a Dealer Agreement, Third Party Loan
Purchase Agreement, Dealer Assignment or Third Party Lender Assignment on the
grounds that it is not a real party in interest or a Person entitled to enforce
the Dealer Agreement, Third Party Loan Purchase Agreement, Dealer Assignment or
Third Party Lender Assignment, the Sellers, at the Sellers' expense, shall take
such steps as the Servicer deems reasonably necessary to enforce the Dealer
Agreement, Third Party Loan Purchase Agreement, Dealer Assignment or Third Party
Lender Assignment, including bringing suit in its name or the name of the
Sellers or of the Trust. All amounts recovered in any legal proceeding shall be
remitted directly by the Servicer to the Lock-Box Bank as provided in Section
2.2(d). Notwithstanding anything to the contrary contained herein, (i) the Note
Insurer may, in its reasonable discretion, direct the Servicer (whether the
Servicer is AmeriCredit or any other Person) to commence or settle any legal
action to enforce collection of any Receivable or to foreclose upon or repossess
any Related Security and (ii) the Servicer shall not make the Collateral Agent
or the Secured Parties a party to any litigation without the prior written
consent of such Person; provided, however, that in the case of subsection (i) of
this sentence, the Servicer may decline or refuse to act on instructions
provided by the Note Insurer if, in the reasonable determination of the
Servicer, such action is not consistent with any Requirements of Law (as defined
in the Note Purchase Agreement) or the Credit and Collection Policy (as defined
in the Security Agreement), or could result in legal or regulatory action
against the Servicer.

          Section 2.4.   Insurance.
                         ---------

          (a)  The Servicer shall require, in accordance with its customary
servicing policies and procedures, that each Financed Vehicle be insured by the
related Obligor under the Insurance Policies and shall monitor the status of
such physical loss and damage insurance coverage thereafter, in accordance with
its customary servicing procedures. Each Receivable requires the Obligor to
maintain such physical loss and damage insurance, naming AmeriCredit and its
successors and assigns as additional insureds, and permits the holder of such
Receivable to obtain physical loss and damage insurance at the expense of the
Obligor if the Obligor fails to maintain such insurance. If the Servicer shall
determine that an Obligor has failed to obtain or maintain a physical loss and
damage Insurance Policy covering the related Financed Vehicle (including,
without limitation, during the repossession of such Financed Vehicle) the
Servicer may enforce the rights of the holder of the Receivable under the
Receivable to require the Obligor to obtain such physical loss and damage
insurance in accordance with its customary servicing policies and procedures.
The Servicer may maintain a vendor's single interest or other collateral
protection insurance policy with respect to all Financed Vehicles ("Collateral
                                                                    ----------
Insurance") which policy shall by its terms insure against physical loss and
---------
damage in the event any Obligor fails to maintain physical loss and damage
insurance with respect to the related Financed Vehicle. All policies of
Collateral Insurance shall be endorsed with clauses providing for loss payable
to the Servicer. Costs incurred by the Servicer in maintaining such Collateral
Insurance shall be paid by the Servicer. The Servicer will administer the filing
of claims under the Insurance Policies.

          (b)  The Servicer may, if an Obligor fails to obtain or maintain a
physical loss and damage Insurance Policy, obtain insurance with respect to the
related Financed Vehicle and

                                       10
<PAGE>

advance on behalf of such Obligor, as required under the terms of the insurance
policy, the premiums for such insurance (such insurance being referred to herein
as "Force-Placed Insurance"). All policies of Force-Placed Insurance shall be
    ----------------------
endorsed with clauses providing for loss payable to the Servicer. Any cost
incurred by the Servicer in maintaining such Force-Placed Insurance shall only
be recoverable out of premiums paid by the Obligors or Net Liquidation Proceeds
with respect to the Receivable, as provided in Section 2.4(c).

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

          (d)  The Servicer may sue to enforce or collect upon the Insurance
Policies, in its own name, if possible, or as agent of the Trust. If the
Servicer elects to commence a legal proceeding to enforce an Insurance Policy,
the act of commencement shall be deemed to be an automatic assignment of the
rights of the Trust under such Insurance Policy to the Servicer for purposes of
collection only. If, however, in any enforcement suit or legal proceeding it is
held that the Servicer may not enforce an Insurance Policy on the grounds that
it is not a real party in interest or a holder entitled to enforce the Insurance
Policy, the Sellers, at the Sellers' expense, shall take such steps as the
Servicer deems necessary to enforce such Insurance Policy, including bringing
suit in its name or the name of the Trust.

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

          Section 2.5.   Maintenance of Security Interests in Vehicles.
                         ---------------------------------------------

          (a)  Consistent with the policies and procedures required by this
Agreement, the Servicer shall take such steps on behalf of the Trust as are
necessary to maintain perfection of the

                                       11
<PAGE>

security interest created by each Contract in the related Financed Vehicle with
respect to each Receivable, including, but not limited to, obtaining the
execution by the Obligors and the recording, registering, filing, re-recording,
re-filing, and re-registering of all security agreements, financing statements
and continuation statements as are necessary to maintain the security interest
granted by the Obligors under the respective Contracts. The Servicer shall take
all action required under Section 2.1 and 2.6 of the Security Agreement with
respect to the notation of Contracts and the marking of records of the Trust.
The Collateral Agent hereby authorizes the Servicer, and the Servicer agrees, to
take any and all steps necessary to re-perfect such security interest on behalf
of the Trust as necessary because of the relocation of a Financed Vehicle or for
any other reason. In the event that the assignment of a Receivable to the Trust
is insufficient, without a notation on the related Financed Vehicle's
certificate of title, or without fulfilling any additional administrative
requirements under the laws of the state in which the Financed Vehicle is
located, to perfect a security interest in the related Financed Vehicle in favor
of the Trust, the Servicer hereby agrees that AmeriCredit's designation as the
secured party on the certificate of title is in its capacity as Servicer as
agent of the Trust.

          (b)  Upon the occurrence of a Termination and Amortization Event, the
Note Insurer may instruct the Collateral Agent and the Servicer to take or cause
to be taken such action as may, in the discretion of the Note Insurer, be
necessary to perfect or re-perfect the security interests in the Financed
Vehicles securing the Receivables in the name of the Trust by amending the title
documents of such Financed Vehicles to name the Collateral Agent on behalf of
the Secured Parties as lienholder or by such other reasonable means as may, in
the opinion of counsel to the Note Insurer, be necessary or prudent. Any costs
associated with such retitling shall be paid by the Servicer and to the extent
not so paid, the Note Insurer shall have the option to pay such costs and shall
be entitled to reimbursement therefor pursuant to Section 2.3(a)(ix) of the
Security Agreement and the Collateral Agent shall not be responsible for any
such costs.

          Section 2.6.   Covenants, Representations, and Warranties of Servicer.
                         ------------------------------------------------------

          (a)  The Servicer covenants as follows:

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

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

          (iii) No Amendments. The Servicer shall not extend or otherwise amend
                -------------
     the terms of any Receivable, except in accordance with Section 2.2; and

          (iv)  Restrictions on Liens. The Servicer shall not (i) create, incur
                ---------------------
     or suffer to exist, or agree to create, incur or suffer to exist, or
     consent to cause or permit in the future (upon the happening of a
     contingency or otherwise) the creation, incurrence or existence

                                       12
<PAGE>

     of any Lien or restriction on transferability of the Receivables except for
     the Lien in favor of the Collateral Agent for the benefit of the Secured
     Parties and the restrictions on transferability imposed by this Agreement
     or (ii) sign or file under the Uniform Commercial Code of any jurisdiction
     any financing statement which names AmeriCredit or the Servicer as a
     debtor, or sign any security agreement authorizing any secured party
     thereunder to file such financing statement, with respect to the
     Receivables, except in each case any such instrument solely securing the
     rights and preserving the Lien of the Collateral Agent, for the benefit of
     the Secured Parties.

          (b)  The Servicer represents and warrants as follows:

          (i)   Representations and Warranties. Each Receivable is an Eligible
                ------------------------------
     Receivable;

     necessary licenses and approvals, in all jurisdictions in which the
     ownership or lease of property or the conduct of its business (including

     shall require such qualification;

          (iv)  Power and Authority. The Servicer has the full power and

     Agreement and the other Transaction Documents to which it is a party have

     articles of incorporation or bylaws of the Servicer, or any indenture,

                         --------------------------------------------------
Representation and Warranty. Upon discovery by either of the Servicer or a
---------------------------
Responsible Officer of the Note Insurer of a breach of any of the covenants set
forth in Sections 2.5(a), 2.6(a), 5.1, 5.2, 5.3 or 5.9, the party discovering
such breach shall give prompt written notice to all of the parties hereto;
provided, however, that the failure to give any such notice shall not affect any
--------  -------
obligation of AmeriCredit as Servicer under this Section. As of the second
Accounting Date following its discovery or receipt of notice of any breach of
any covenant set forth in Sections 2.5(a), 2.6(a), 5.1, 5.2, 5.3 or 5.9 which
materially and adversely affects the interests of the Secured Parties in any

the first Accounting Date so following) or the related Financed Vehicle,
AmeriCredit shall, unless such breach shall have been cured in all material

related Determination Date, AmeriCredit shall pay the related Purchase Amount to
the Trust. It is understood and agreed that the obligation of AmeriCredit to
purchase any Receivable (including any Defaulted Receivable) with respect to
which such a breach has occurred and is continuing shall, if such obligation is
fulfilled, constitute the sole remedy against AmeriCredit for such breach
available to the Secured Parties or the Collateral Agent except as otherwise
provided in the Insurance Agreement; provided, however, that AmeriCredit shall
                                     --------  -------

AmeriCredit Corp. and that (1) such audit was made in accordance with generally
accepted auditing standards, and accordingly included such tests of the
accounting records and such other auditing procedures as such firm considered
necessary in the circumstances; (2) the firm is independent of the Servicer
within the meaning of the Code of Professional Ethics of the American Institute
of Certified Public Accountants, and (3) includes a report on the application of

Regarding Receivables. The Servicer shall provide to representatives of the

regarding the Receivables. In each case, such access shall be afforded without
charge and, provided no Servicer Termination Event or Potential Termination and
Amortization Event shall have occurred, only upon reasonable request and during
normal business hours. Nothing in this Section shall affect the obligation of
the Servicer to observe any applicable law prohibiting disclosure of information
regarding the Obligors, and the failure of the Servicer to provide access as
provided in this Section as a result of such obligation shall not constitute a
breach of this Section.

use such tape or diskette (or other electronic transmission acceptable to the
Collateral Agent) to (i) confirm that the Servicer's Certificate is complete,
(ii) confirm that such tape, diskette or other electronic transmission is in
readable form, (iii) verify the mathematical accuracy of all calculations
contained within the Servicer's Certificate and (iv) calculate and confirm any

it has verified the Servicer's Certificate in accordance with this Section and
shall notify the Servicer and the Note Insurer of any discrepancies, in each
case, on or before the second Business Day following the Remittance Date. In the
event that the Collateral Agent reports any discrepancies, the Servicer and the
Collateral Agent shall attempt to reconcile such discrepancies prior to the next
succeeding Remittance Date, but in the absence of a reconciliation, the
Servicer's Certificate shall control for the purpose of calculations and
distributions with respect to the next succeeding Remittance Date. In the event
that the Collateral Agent and the Servicer are unable to reconcile discrepancies
with respect to a Servicer's Certificate by the next succeeding Remittance Date,
the Servicer shall cause the Independent Accountants, at the Servicer's expense,
to audit the Servicer's Certificate and, prior to the last day of the month
after the month in which such Servicer's Certificate was delivered, reconcile
the discrepancies. The effect, if any, of such reconciliation shall be reflected
in the Servicer's Certificate for the next succeeding Remittance Date, and/or
the Servicer's Certificate for such next succeeding Determination Date. In
addition, upon the occurrence of a Servicer Termination Event the Servicer
shall, if so requested by the Note Insurer, deliver to the Collateral Agent its
Collection Records and its Monthly Records within 15 days after demand therefor

taken or omitted by the Servicer.

that may at any time be asserted against any of such parties with respect to the
transactions contemplated in this Agreement, including, without limitation, any
sales, gross receipts, tangible or intangible personal property, privilege or
license taxes (but not including any federal or other income taxes, including
franchise taxes asserted with respect to, and as of the date of, the sale of the

in defending against the same;

          (c)  The Servicer shall indemnify, defend and hold harmless the Trust,
the Trustee, and the Collateral Agent, the Secured Parties and their respective
officers, directors, agents and employees from and against any and all costs,
expenses, losses, claims, damages, and liabilities to the extent that such cost,
expense, loss, claim, damage, or liability arose out of, or was imposed upon the
Trust, the Trustee, the Collateral Agent or the Secured Parties by reason of the
breach of this Agreement by the Servicer, the negligence, misfeasance, or bad
faith of the Servicer in the performance of its duties under this Agreement or
by reason of reckless disregard of its obligations and duties under this
Agreement;

under the Transaction Documents other than if such loss, liability or expense is
conclusively determined by a judicial proceeding to have been incurred by the
Collateral Agent as a result of any such entity's willful misconduct, bad faith
or negligence,; and

          (e)  Indemnification under this Article shall survive the termination
of the Transaction Documents or the resignation and removal of the Trustee and
the Collateral Agent and shall include, without limitation, reasonable fees and
expenses of counsel and expenses of litigation. If the Servicer has made any
indemnity payments pursuant to this Article and the recipient thereafter
collects any of such amounts from others, the recipient shall promptly repay
such amounts collected to the Servicer, without interest.

          Section 3.2.   Merger or Consolidation of, or Assumption of the
                         ------------------------------------------------
Obligations of the Servicer. AmeriCredit shall not merge or consolidate with any

Any corporation (i) into which AmeriCredit

or filing of any paper or any further act on the part of any of the parties to
this Agreement, anything in this Agreement to the contrary notwithstanding;
provided, however, that nothing contained herein shall be deemed to release

consolidation or succession pursuant to this Section to the Collateral Agent and
the Secured Parties. Notwithstanding the foregoing, AmeriCredit shall not merge
or consolidate with any other Person or permit any other Person to become a
successor to AmeriCredit's business, unless (x) immediately after giving effect
to such transaction, no representation or warranty made pursuant to Section 2.6
shall have been breached (for purposes hereof, such representations and
warranties shall speak as of the date of the consummation of such transaction)
and no Termination and Amortization Event or Potential Termination and
Amortization Event shall have occurred and be continuing, (y) AmeriCredit shall
have delivered to the Collateral Agent and the Note Insurer an Officer's
Certificate and an Opinion of Counsel each stating that such consolidation,
merger or succession and such agreement of assumption comply with this Section
and that all conditions precedent, if any, provided for in this Agreement
relating to such transaction have been complied with, and (z) AmeriCredit shall
have delivered to the Collateral Agent and the Note Insurer an Opinion of
Counsel, stating in the opinion of such counsel, either (A) all financing
statements and continuation statements and amendments thereto have been executed
and filed that are necessary to preserve and protect the interest of the Trust
in the Receivables and the Other Conveyed Property and reciting the details of
the filings or (B) no such action shall be necessary to preserve and protect
such interest.

          Section 3.3.   Limitation on Liability of Servicer and Others. None of
                         ----------------------------------------------
AmeriCredit nor any of the directors or officers or employees or agents of
AmeriCredit shall be under any liability to the Trust or the Secured Parties,
except as provided in this Agreement, for any action taken or for refraining
from the taking of any action pursuant to this Agreement; provided, however,
that this provision shall not protect AmeriCredit or any such person against any
liability that would otherwise be imposed by reason of a breach of this
Agreement or willful misfeasance, bad faith or negligence in the performance of
duties; provided further that this provision shall not affect any liability to
indemnify the Collateral Agent for costs, taxes, expenses, claims, liabilities,
losses or damages paid by the Collateral Agent, in its individual capacity.
AmeriCredit and any director, officer, employee or agent of AmeriCredit may rely
in good faith on the written advice of counsel selected by it with due care or

consent of the Note Insurer and may perform other specific duties through such

<PAGE>

in accordance with Servicer's customary servicing policies and procedures, with
the prior consent of the Note Insurer; provided, however, that no such
                                       --------  -------
delegation or sub-contracting duties by the Servicer shall relieve the Servicer
of its responsibility with respect to such duties. Neither AmeriCredit or any
party acting as Servicer hereunder shall appoint any subservicer hereunder

                         ----------------------
Section 3.2, the Servicer shall not resign from the obligations and duties
imposed on it by this Agreement as Servicer except upon a determination that by
reason of a change in legal requirements the performance of its duties under
this Agreement would cause it to be in violation of such legal requirements in a
manner which would have a material adverse effect on the Servicer and the Note
Insurer does not elect to waive the obligations of the Servicer to perform the
duties which render it legally unable to act or to delegate those duties to
another Person. Any such determination permitting the resignation of the
Servicer shall be evidenced by an Opinion of Counsel to such effect delivered
and acceptable to the Note Insurer. No resignation of the Servicer shall become
effective until a successor Servicer that is an eligible servicer as approved by
the Note Insurer, shall have assumed the responsibilities and obligations of the
Servicer.

regarding the duties of the Debtor under the Transaction Documents. The Servicer
shall monitor the performance of the Debtor and shall advise the Trustee when
action is necessary to comply with the Debtor's duties under the Transaction
Documents. The Servicer shall prepare for execution by the Trustee or shall
cause the preparation by other appropriate Persons of all such documents,

Agreement or any of the Transaction Documents, the Servicer shall perform such
calculations and shall prepare, or shall cause the preparation, for execution by
the Trustee or other appropriate Persons of all such documents, reports,
filings, instruments, certificates and opinions as it shall be the duty of the

securities laws. The Servicer shall administer, perform or supervise the
performance of such other activities in connection with the Debtor as are not
covered by any of the foregoing provisions and as are expressly requested by the
Trustee and are reasonably within the capability of the Servicer.

          (ii)  Notwithstanding anything in this Agreement or any of the
Transaction Documents to the contrary, the  Servicer shall be responsible for
promptly notifying the Trustee in the event that any withholding tax is imposed
on the Debtor's payments (or allocations of income) to a Certificateholder.  Any
such notice shall be in writing and specify the amount of any withholding tax
required to be withheld by the Trustee pursuant to such provision.

          (d)  The Servicer shall materially modify the Credit and Collection
Policy, unless it has given the Note Insurer prompt notification of such
modification and the Note Insurer has determined in its reasonable discretion
that such modification is not a material adverse change;

"event of default" or "default" under any such agreement; or any Indebtedness
owing by the Servicer or any Subsidiary of the Servicer greater than such
respective amounts shall be declared to be due and payable or required to be
prepaid (other than by a regularly scheduled payment) prior to the date of

with the consent of the Note Insurer, by notice given in writing to the Servicer
may, or at the direction of the Note Insurer shall, terminate all of the rights

under this Agreement, whether with respect to the Receivables or the Other
Conveyed Property (as defined in the Master Receivables Purchase Agreement) or
otherwise, automatically shall pass to, be vested in and become obligations and
responsibilities of a successor Servicer acceptable to the Note Insurer);
provided, however, that the successor Servicer shall have no liability with
--------  -------
respect to any obligation which was required to be performed by the terminated
Servicer prior to the date that the successor Servicer becomes the Servicer or
any claim of a third party based on any alleged action or inaction of the
terminated Servicer. The successor Servicer is authorized and empowered by this
Agreement to execute and deliver, on behalf of the terminated Servicer, as
attorney-in-fact or otherwise, any and all documents and other instruments and
to do or accomplish all other acts or things necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and
endorsement of the Receivables and the Other Conveyed Property and related
documents to show the Trust as lienholder or secured party on the related Lien
Certificates, or otherwise. The terminated Servicer agrees to cooperate with the
successor Servicer in effecting the termination of the responsibilities and
rights of the terminated Servicer under this Agreement, including, without
limitation, the transfer to the successor Servicer for administration by it of
all cash amounts that shall at the time be held by the terminated Servicer for
deposit, or have been deposited by the terminated Servicer, in the Collection
Account or thereafter received with respect to the Receivables and the delivery
to the successor Servicer of all Receivable Files, Monthly Records and
Collection Records and a computer tape in readable form as of the most recent

          Section 4.3.   Appointment of Successor.
                         ------------------------

          (a)  On and after the time the Servicer receives a notice of
termination pursuant to Section 4.2, or upon the resignation of the Servicer,
the Collateral Agent shall appoint an alternate successor Servicer upon written
direction from the Note Insurer, provided that any successor Servicer may not be
an Affiliate (as defined in the Security Agreement) of the Note Insurer, who
shall be subject to all the rights, responsibilities, restrictions, duties,
liabilities and termination provisions relating thereto placed on the Servicer
by the terms and provisions of this Agreement except as otherwise stated herein.
The Collateral Agent and such successor shall take such action, consistent with
this Agreement, as shall be necessary to effectuate any such succession. If a
successor Servicer is acting as Servicer hereunder, it shall be subject to
termination under Section 4.2 upon the occurrence of any Servicer Termination
Event applicable to it as Servicer.

          (b)  Any successor Servicer shall be entitled to such compensation
(whether payable out of the Collection Account or otherwise) as the Servicer
would have been entitled to under this Agreement if the Servicer had not
resigned or been terminated hereunder. The Collateral Agent and such successor
Servicer may agree on additional reasonable compensation to be paid to such
successor Servicer. In addition, any successor Servicer shall be entitled to
reasonable transition expenses incurred in acting as successor Servicer.

          Section 4.4.   Notification to Secured Parties. Upon any termination
                         -------------------------------
of, or appointment of a successor to, the Servicer, the Collateral Agent shall
give prompt written notice thereof to each Secured Party.

          Section 4.5.   Waiver of Past Defaults. The Agent may, on behalf of
                         -----------------------
all Secured Parties, waive any default by the Servicer in the performance of its
obligations hereunder and its consequences. Upon any such waiver of a past
default, such default shall cease to exist, and any Servicer Termination Event
arising therefrom shall be deemed to have been remedied for every purpose of
this Agreement. No such waiver shall extend to any subsequent or other default
or impair any right consequent thereto.

                                 THE CUSTODIAN
                                 -------------

          Section 5.1.   Appointment of Custodian; Acknowledgment of Receipt;
                         ----------------------------------------------------
Monthly Exception Reports. Subject to the terms and conditions hereof, the
-------------------------
Collateral Agent hereby revocably appoints the Custodian and the Custodian
hereby accepts such appointment, as custodian and bailee on behalf of the
Collateral Agent (for the benefit of the Secured Parties) to maintain exclusive
custody of the Receivable Files relating to the Receivables from time to time
held as part of the Collateral; provided, however, that neither the Collateral
                                --------  -------
Agent nor any Secured Party shall be responsible for the acts or omissions of
the Custodian. In performing its duties hereunder, the Custodian agrees to act
with that degree of care, skill and attention that a commercial bank acting in
the capacity of a custodian would exercise with respect to files relating to
comparable automotive or other receivables that it services or holds for itself
or others, and, in any event, to exercise at least that degree of care, skill
and attention that it

                                       23
<PAGE>

exercises with respect to its own assets. The Custodian, as of each Receivables
Transfer Date with respect to the Receivables sold on such date, hereby
acknowledges receipt of the Receivable File for each Receivable listed in the
Schedules of Receivables attached to the related Supplement, subject to any
exceptions noted on the applicable Custodian's Acknowledgment. As evidence of
its acknowledgement of such receipt of such Records, the Custodian shall execute
and deliver to the Collateral Agent and the Note Insurer on each Receivables
Transfer Date with respect to the Receivables sold on such date, the Custodian's
Acknowledgement in the form attached hereto as Schedule A. In addition, the
Custodian shall deliver to the Collateral Agent and the Note Insurer a monthly
exception report in the form attached as Exhibit B hereto. AmeriCredit shall be
required to repurchase the Receivables listed on the monthly exception report
pursuant to Section 2.7 hereof, in the event that the related Lien Certificates
are indicated as not having been received by the 181st day following the date of
origination of the related Receivables.

          Section 5.2.   Maintenance of Records at Office. The Custodian agrees
                         --------------------------------
to maintain the Receivable Files at 4001 Embarcadero Drive, Arlington, Texas
76014 or at such other office as shall from time to time be identified to the
Collateral Agent and the Note Insurer, and the Custodian will hold the
Receivable Files in such office on behalf of the Collateral Agent (for the
benefit of the Secured Parties), clearly identified on its records as being
separate from any other instruments and files, including other instruments and
files held by the Custodian, and in compliance with Section 5.3(b) hereof.

          Section 5.3.   Duties of Custodian.
                         -------------------

          (a)  Safekeeping. (i) The Custodian shall hold the Receivable Files on
               -----------
behalf of the Collateral Agent (for the benefit of the Secured Parties) clearly
identified as being separate from all other files or records maintained by the
Custodian, whether at the same or any other location, and shall maintain such
accurate and complete accounts, records or computer systems pertaining to each
Receivable File as are required to comply with the terms and conditions of the
Note Purchase Agreement. Each Contract shall be stamped on both of the first
page and the signature page (if different) in accordance with the requirements
of any Opinion of Counsel or as otherwise is deemed necessary or desirable by
the Collateral Agent and the Note Insurer. Each Receivable shall be identified
on the books and records of the Custodian in an manner that (x) is consistent
with the practices of a commercial bank acting in the capacity of custodian with
respect to similar receivables, (y) indicates that the Receivables are held by
the Custodian on behalf of the Collateral Agent and (z) is otherwise necessary,
as reasonably determined by the Custodian, to comply with the terms of this
Agreement. The Custodian shall conduct, or cause to be conducted, periodic
physical inspections of the Receivable Files held by it under this Agreement,
and of the related accounts, records and computer systems, in such a manner as
shall enable the Collateral Agent, the Note Insurer and the Custodian to verify
the accuracy of the Custodian's inventory and recordkeeping. Such inspections
shall be conducted at such times, in such manner and by such persons, including,
without limitation, independent accountants, as the Collateral Agent and the
Note Insurer may request and the cost of such inspections shall be borne by the
Custodian. The Custodian shall promptly report to the Collateral Agent and the
Note Insurer any failure on the Custodian's part to hold the Receivable Files
and maintain its accounts, records and computer systems as herein provided and
the Custodian shall promptly take appropriate action to remedy any such failure.

                                       24
<PAGE>

          (ii) Notwithstanding the above paragraph (i), upon a Servicer
Termination Event, at the direction of the Note Insurer, the Custodian shall
deliver the Receivable Files within 30 days of such notice to the Collateral
Agent and the Collateral Agent shall hold such Receivable Files on behalf of the
Secured Parties. Subject to Section 5.3(c) hereof and the preceding sentence,
the Custodian shall at all times maintain the original of the fully executed
original retail installment sales contract or promissory note and of the Lien
Certificate or application therefore, if no such Lien Certificate has yet been
issued, relating to each Receivable in a fire resistant vault.

          (b)  Access to Records. The Custodian shall, subject only to the
               -----------------
Custodian's security requirements applicable to its own employees having access
to similar records held by the Custodian, which requirements shall be consistent
with the practices of a commercial bank acting in the capacity of custodian with
respect to similar files or records, and at such times as may be reasonably
imposed by the Custodian, permit only the Secured Parties and the Collateral
Agent or their duly authorized representatives, attorneys or auditors to inspect
the Receivable Files and the related accounts, records, and computer systems
maintained by the Custodian pursuant hereto at such times as any of the Secured
Parties or the Collateral Agent may reasonably request.

          (c)  Release of Documents. The Custodian shall release such Receivable
               -----------------
Files to the Servicer only (1) upon payment in full of such Receivable or (2) as
required from time to time as appropriate for servicing and enforcing any
Receivable but, in the case of clause (1) or (2), only as is consistent with the
terms of the Note Purchase Agreement and the Security Agreement.

          (d)  Administration; Reports. The Custodian shall, in general, attend
               -----------------------
to all ministerial matters in connection with maintaining custody of the
Receivable Files on behalf of the Collateral Agent. In addition, the Custodian
shall assist the Collateral Agent or the Servicer, as the case may be, in the
preparation of any routine reports to Secured Parties or to regulatory bodies,
to the extent necessitated by the Custodian's custody of the Receivable Files.

          Section 5.4.   Instructions; Authority to Act. The Custodian shall be
                         ------------------------------
deemed to have received proper instructions with respect to the Receivable Files
upon its receipt of written instructions signed by a Responsible Officer of the
Collateral Agent. Such instructions may be general or specific in terms.

          Section 5.5.   Custodian Fee. For its services under this Agreement,
                         -------------
the Custodian shall be entitled to reasonable compensation to be paid by the
Servicer.

          Section 5.6.   Indemnification by the Custodian. The Custodian agrees
                         --------------------------------
to indemnify the Secured Parties, the Trust, the Note Insurer, the Trustee and
the Collateral Agent for any and all liabilities, obligations, losses, damage,
payments, costs or expenses of any kind whatsoever (including the fees and
expenses of counsel) that may be imposed on, incurred or asserted against any of
the Secured Parties, the Trust, the Note Insurer and/or the Collateral Agent as
the result of any act or omission in any way relating to the maintenance and
custody by the Custodian of the Receivable Files or any default by the Custodian
of its obligations hereunder; provided, however, that the Custodian shall not be
                              --------  -------
liable to any party indemnified
                                       25
<PAGE>

hereunder for any portion of any such liabilities, obligations, losses, damages,
payments or costs or expenses as are due to the willful misfeasance, bad faith
or gross negligence of such indemnified party.

          Section 5.7.   Advice of Counsel. The Custodian shall be entitled to
                         -----------------
rely and act upon advice of counsel selected by it with due care with respect to
its performance hereunder as custodian and shall be without liability for any
action reasonably taken in good faith pursuant to such advice, provided that
such action is not in violation of applicable federal or state law.

          Section 5.8.   Effective Period, Termination, and Amendment;
                         ---------------------------------------------
Interpretive and Additional Provisions. This Agreement shall become effective as
--------------------------------------
of the date hereof and shall continue in full force and effect until terminated
as hereinafter provided. This Agreement may be amended at any time by agreement
of the Collateral Agent, the Note Insurer and the Custodian and the rights and
obligations of the Servicer and the Custodian may be terminated by the Note
Insurer following a Termination and Amortization Event; provided so long as
                                                        --------
AmeriCredit is Custodian, the Custodian shall not resign from the obligations
and duties imposed on it by this Agreement, except upon a determination that by
reason of a change in legal requirements, the performance of its duties under
this Agreement would cause it to be in violation of such legal requirements in a
manner which would have a material adverse effect on it and the Note Insurer
does not elect to waive the obligations of the Custodian to perform the duties
which render it legally unable to act or to delegate those duties to another
Person; provided, further, that any such determination permitting the
        --------  -------
resignation of the Custodian shall be evidenced by an Opinion of Counsel to such
effect delivered to the Note Insurer and the Collateral Agent that is acceptable
to the Note Insurer. So long as AmeriCredit is serving as Custodian, any
termination of AmeriCredit as Servicer under the Note Purchase Agreement or the
Security Agreement shall terminate AmeriCredit as Custodian under this
Agreement. Immediately after receipt of notice of termination of this Agreement,
the Custodian shall deliver the Receivable Files to the Collateral Agent on
behalf of the Secured Parties, at such place or places as the Collateral Agent
may designate, and the Collateral Agent, or its agent, as the case may be, shall
act as custodian for such Records on behalf of the Secured Parties until such
times as a successor custodian acceptable to the Note Insurer has been appointed
by the Collateral Agent. (For the avoidance of doubt, during any such period,
the Collateral Agent shall be acting in its capacity as Collateral Agent,
including the standard of care and liability in such capacity, and not as a
successor "Custodian" hereunder.) If, within 30 days after the termination of
           ---------
this Agreement, the Custodian has not delivered the Receivable Files in
accordance with the preceding sentence, the Collateral Agent may enter the
premises of the Custodian and remove the Receivable Files from such premises. In
connection with the administration of this Agreement, the parties may agree from
time to time upon the interpretation of the provisions of this Agreement as may
in their joint opinion be consistent with the general tenor and purposes of this
Agreement, any such interpretation to be signed by all parties and annexed
hereto.

each of the Secured Parties that as of the date of each Custodian's
Acknowledgment: (i) it holds no adverse interest, by way of security or
