2.1      Funding

         (a)   Initial Loan Note Funding. Upon the terms and subject to the
               conditions herein set forth, provided that the Facility
               Termination Date shall not have occurred, the Lender shall make
               an initial advance (the "Initial Loan Note Funding") to the
               Borrower on or after the Closing Date. In connection with the
               Initial Loan Note Funding, the Borrower shall, by notice in the
               form of Exhibit A hereto (the "Funding Notice") request such
               Funding by noon (Toronto time) at least one Business Day prior to
               the proposed date of such Initial Loan Note Funding. Such notice
               shall specify the proposed Funding amount (which shall be at
               least Cdn.$1,000,000) and the proposed date of the Initial Loan
               Note Funding and shall include the Borrowing Base calculation and
               a spreadsheet file containing the field names listed in Exhibit C
               hereto.

         (b)   Subsequent Loan Note Fundings. Upon the terms and subject to the
               conditions herein set forth, provided that the Facility
               Termination Date shall not have occurred, the Lender shall make
               subsequent advances from time to time (each, a "Subsequent Loan
               Note Funding") to the Borrower on or after the Funding Date. In
               connection with each Subsequent Loan Note Funding, the Borrower
               shall, by noon (Toronto time) on the Business Day prior to the
               related Funding Date, provide the Lender with a Funding Notice
               setting forth the amount of the proposed Subsequent Loan Note
               Funding, which shall be at least Cdn.$1,000,000 and integral
               multiples of Cdn.$100,000 in excess thereof (or, to the extent
               that the then available unused portion of the Facility Limit is
               less than such amount, such amount) and shall include the
               Borrowing Base calculation and a spreadsheet file containing the
               field names listed in Exhibit C hereto.

         (c)   Limitation of Liability. By making any advance hereunder, the
               Lender does not assume nor shall it or the Collateral Agent have
               any obligations or liabilities

<PAGE>

                                      -3-

               under any of the Receivables or with respect to any of the
               Related Security, all of which shall remain the obligations and
               liabilities of the Borrower.

         (d)   Conditions to Funding. The Lender shall have no obligation to
               advance any funds to the Borrower in connection with any Funding
               if on the date of the proposed Funding, (i) the Net Loan
               Investment after giving effect to the Funding would exceed the
               Borrowing Base; (ii) the Borrower shall not have given
               irrevocable instructions to the Lender to direct from proceeds of
               such Funding, the Cash Reserve Account Required Amount into the
               Cash Reserve Account; (iii) a Potential Termination Event or a
               Termination Event shall have occurred and be continuing; (iv) the
               conditions precedent set forth in Article 5 hereof (to the extent
               that they apply to such Funding) shall not be satisfied; (v) the
               representations and warranties in Section 3.1 of the Security
               Agreement shall not be true and correct on such day; or (vi) the
               Facility Termination Date shall have occurred.

         (e)   Funding Notices Irrevocable. The Funding Notices shall be
               irrevocable and binding on the Borrower and the Borrower shall
               indemnify the Lender against any loss or expense incurred by the
               Lender, either directly or indirectly as a result of any failure
               by the Borrower to complete the requested Funding including,
               without limitation, any loss (excluding loss of anticipated
               profits) or expense incurred by the Lender, either directly or
               indirectly, by reason of the liquidation or re-employment of
               funds acquired by the Lender for the Lender to complete the
               requested Funding.

         (f)   Payments. By no later than 1:00 p.m. (Toronto time) on the date
               of any Funding, the Lender shall remit the amount of such Funding
               to be advanced by the Lender to the Borrower as set forth in the
               applicable Funding Notice, as the case may be, to the Borrower's
               account as directed in the Funding Notice.

         (g)   The Loan Note.

               (i)  The Borrower's obligation to pay the principal of and
                    interest on all amounts advanced by the Lender pursuant to
                    any Funding shall be evidenced by a single note of the
                    Borrower (the "Loan Note") payable to the Collateral Agent
                    on behalf of the Lender which shall (1) be dated May 9,
                    2002; (2) be in the stated principal amount described
                    therein; (3) bear interest as provided herein and therein;
                    (4) be payable to the order of the Collateral Agent on
                    behalf of the Lender and mature on the Settlement Date
                    occurring in the eighth calendar month following the
                    calendar month in which the latest maturing Receivable
                    (determined as of the Facility Termination Date) is
                    scheduled to mature (without regard to extensions
                    subsequently granted on any Receivable by the Borrower); (5)
                    be entitled to the benefit of the Security Agreement; and
                    (6) be substantially in the form of Exhibit B to this
                    Agreement, with blanks appropriately completed in conformity
                    herewith. The Collateral Agent shall, and is hereby
                    authorized to, make a notation on the schedule attached to
                    the Loan Note of the date and the amount of each Funding and
                    the date and amount of the payment of principal thereon;
                    provided, however, that failure to make such

<PAGE>
                                      -4-

                    notation shall not adversely affect the Collateral Agent's
                    rights with respect to the Loan Note.

               (ii) Although the Loan Note shall be dated May 9, 2002, interest
                    in respect thereof shall be payable only for the periods
                    during which amounts are outstanding thereunder.

2.2      Interest

         (a)   The Borrower shall pay to the Lender interest on the Net Loan
               Investment monthly in arrears in respect of each Monthly Period
               on the Settlement Date immediately following such Monthly Period
               which interest shall be calculated for each Monthly Period as
               follows:

               (i)  for the portion of such Monthly Period ending prior to the
                    occurrence of a Termination Event,

                               BAR x NLI x ED/365

               (ii) for the portion of such Monthly Period ending on or after
                    the date of occurrence of a Termination Event,

                                PR x NLI x ED/365

               where:

                    BAR = the applicable BA Rate for such Monthly Period

                    NLI = the weighted average Net Loan Investment for the
                    applicable portion of such Monthly Period

                    PR = the applicable Prime Rate plus 3.50% for such Monthly
                    Period

                    ED = the actual number of days in the applicable portion of
                    such Monthly Period during which the Net Loan Investment was
                    outstanding and being funded at the BA Rate or the Prime
                    Rate plus 3.5%, as applicable;

                    provided, that any interest paid on the Net Loan Investment
                    shall not be considered paid by any distribution to the
                    Lender on account of interest to the extent that at any time
                    all or a portion of such distribution is rescinded or must
                    otherwise be returned for any reason.

         (b)   Interest on any amount payable to the Lender under this Agreement
               or any other Transaction Document which is not paid when due
               shall be calculated daily at a rate per annum equal to the Prime
               Rate plus 3.5% in the outstanding amount thereof and shall accrue
               from the due date therefore, until payment in full of such
               amount. Such interest shall be payable upon demand by the Lender.

<PAGE>

                                      -5-

         (c)   Interest payable hereunder shall be calculated on the basis of a
               three hundred sixty five (365) day year, and actual days elapsed.

         (d)   The Lender shall determine the CDOR Rate on the first day of each
               month for the purposes of calculating the BA Rate for the Monthly
               Period commencing on such date. The Prime Rate for each Monthly
               Period and for all other purposes of this Agreement shall be the
               Prime Rate in effect as of the opening of business on the first
               day of each month.

         (e)   For purposes of disclosure under the Interest Act (Canada), where
               interest is calculated pursuant hereto at a rate based upon a
               three hundred and sixty-five (365) or three hundred and sixty
               (360) day year (the "First Rate"), it is hereby agreed that the
               rate or percentage of interest on a yearly basis is equivalent to
               such First Rate multiplied by the actual number of days in the
               year divided by three hundred and sixty-five (365) or three
               hundred and sixty (360), as applicable.

         (f)   In no event shall charges constituting interest payable by the
               Borrower to the Lender exceed the maximum amount or the rate
               permitted under any applicable law or regulation, and if any part
               or provision of this Agreement is in contravention of any such
               law or regulation, such part or provision shall be deemed amended
               to conform thereto. Notwithstanding the provisions of this
               Agreement, in no event shall the aggregate "interest" (as that
               term is defined in Section 347 of the Criminal Code (Canada))
               exceed the effective annual rate of interest on the "credit
               advanced" (as defined therein) lawfully permitted under Section
               347 of the Criminal Code (Canada). The effective annual rate of
               interest shall be determined in accordance with generally
               accepted actuarial practices and principles over the term of the
               applicable Funding, and in the event of a dispute, a certificate
               of a Fellow of the Canadian Institute of Actuaries appointed by
               Lender will be conclusive for the purposes of such determination.

         (g)   A certificate of an authorized signing officer of the Lender as
               to each amount and/or each rate of interest payable hereunder
               from time to time shall be conclusive evidence of such amount and
               of such rate, absent manifest error.

         (h)   For greater certainty, whenever any amount is payable under this
               Agreement or any other Transaction Document by Borrower as
               interest or as a fee which requires the calculation of an amount
               using a percentage per annum, each party to this Agreement
               acknowledges and agrees that such amount shall be calculated as
               of the date payment is due without application of the "deemed
               reinvestment principle" or the "effective yield method". As an
               example, when interest is calculated and payable monthly, the
               rate of interest payable per month is 1/12 of the stated rate of
               interest per annum.

2.3      Optional Prepayments

The Borrower may prepay the Fundings made to it, in whole or in part, without
premium or penalty, upon at least three (3) Business Days' irrevocable notice to
the Lender specifying the date and amount of prepayment, or upon less notice
provided that if less than three (3) Business Days' notice is provided to the
Lender the Borrower shall be responsible for the reasonable

<PAGE>

                                      -6-

breakage costs incurred by the Lender as a result of such prepayment. If any
such notice is given, the amount specified in such notice shall be due and
payable on the date specified therein, together with accrued interest thereon
calculated at the then applicable rate hereunder.

                                    ARTICLE 3
                                TERM AND DEFAULT

3.1      Term of Agreement

The initial term of this Agreement and the facility described herein shall be
364 days from the Closing Date (the "Initial Commitment Expiry Date"). The
Borrower may, by written request (an "Extension Request") to the Lender
delivered at least sixty days preceding each anniversary of the then applicable
Commitment Expiry Date, request that the Lender extend the Commitment Expiry
Date then in effect by a further 364 day period. The Lender shall notify the
Borrower and AmeriCredit Canada no later than 5:00 p.m., Toronto time, on the
date which is thirty days after delivery of an Extension Request, of whether the
Lender agrees to extend the Commitment Expiry Date by 364 days. If the Lender
has failed to notify the Borrower and AmeriCredit Canada within such 30 day
period its consent shall be deemed to have been denied. If the Lender agrees in
writing to so extend a Commitment Expiry Date by 364 days, then such Commitment
Expiry Date shall automatically be so extended.

3.2      Default

The Borrower shall be in default under this Agreement upon the occurrence of any
Termination Event and the Collateral Agent may with the consent of the Lender
and shall upon the direction of the Lender subsequently declare that the
Facility Termination Date shall have occurred (in which case the Facility
Termination Date shall be deemed to have occurred), provided that automatically
upon the commencement or occurrence of any Insolvency Event with respect to the
Seller (without the requirement for passage of time or giving of notice) the
Facility Termination Date shall occur, and the Collateral Agent may accelerate
the obligations owing to the Lender hereunder or under the Loan Note and may
exercise the other rights and remedies set out in the Security Agreement and the
other Transaction Documents and, in the case of a Servicer Termination Event,
the Servicing Agreement and may exercise all other rights and remedies provided
after default under the applicable PPSA and under other applicable law, which
rights and remedies shall be cumulative.

                                    ARTICLE 4
                                 INDEMNIFICATION

4.1      Indemnity

Without limiting any other rights which the Lender may have hereunder or under
applicable law, each of the Borrower and AmeriCredit Canada agrees to jointly
and severally indemnify the Lender, the Collateral Agent and any permitted
assigns and their respective agents, officers, directors and employees
(collectively, "Indemnified Parties") from and against any and all claims,
damages, expenses, losses and liabilities (including Legal Costs) (all of the
foregoing being collectively referred to as "Indemnified Amounts") awarded
against or incurred by any of them in any action or proceeding between the
Borrower, AmeriCredit Canada and any of the Indemnified Parties or between any
of the Indemnified Parties and any third party or otherwise

<PAGE>

                                      -7-

arising out of or as a result of this Agreement, the Loan Note or the other
Transaction Documents or any other transactions contemplated hereby or thereby
excluding, however, (i) Indemnified Amounts to the extent resulting from gross
negligence or willful misconduct on the part of an Indemnified Party or (ii)
recourse for uncollectible Receivables or (iii) (except as otherwise
specifically provided in this Agreement) any income (including withholding)
taxes or franchise taxes or capital taxes. Such Indemnified Amounts shall be
paid in accordance with the Security Agreement. Without limiting, or being
limited by the generality of the foregoing, but subject to the exclusions set
forth in the second preceding sentence, each of the Borrower and AmeriCredit
Canada shall indemnify each Indemnified Party from and against any and all
Indemnified Amounts relating to or resulting from:

         (a)   any representation or warranty made by the Borrower, Seller or
               AmeriCredit Canada under or in connection with this Agreement,
               the Security Agreement, any other Transaction Document, any
               Funding Notice, Servicer's Report (to the extent prepared by
               AmeriCredit Canada as Servicer) or any other information or
               report delivered by the Borrower or AmeriCredit Canada pursuant
               hereto or thereto, which shall have been false or incorrect in
               any material respect when made or deemed made;

         (b)   the failure by the Borrower, AmeriCredit Canada, Seller,
               AmeriCredit Financial Services, Inc. or the Temporary Custodian

               respect to the Collateral, or the nonconformity of any portion of
               the Collateral with any such applicable law, rule or regulation;

         (c)   the failure to vest and maintain vested in the Collateral Agent a
               first priority perfected security interest in the Collateral,
               free and clear of any Adverse Claim;

         (d)   the failure to file, or any delay in filing, financing statements
               or other similar instruments or documents under the PPSA or
               Uniform Commercial Code as adopted by the State of Texas with
               respect to all or any part of the Collateral which failure has an
               adverse effect on the validity, perfected status or priority of
               the security interest granted to the Collateral Agent under the
               Security Agreement;

         (e)   any dispute, claim, offset or defense (other than discharge in
               bankruptcy of the Obligor) of the Obligor to the payment of any
               Receivable (including, without limitation, a defense based on
               such Receivable not being legal, valid and binding obligation of
               such Obligor enforceable against it in accordance with its
               terms), or any other claim resulting from the sale of services
               related to such Receivable or the furnishing or failure to
               furnish such services;

         (f)   any products liability claim or personal injury or property
               damage suit or other similar or related claim or action of

               to insure the Financed Vehicle;

               Borrower other than an Eligible Receivable;

(h)  the failure by the Borrower, AmeriCredit Canada, Seller, AmeriCredit
     Financial Services, Inc. or the Temporary Custodian to comply with any

     or to perform any of its respective duties under the Receivables or the
     Contracts;

(i)  the acceptance or administration of the Trust by any Indemnified Party and
     the performance of such Indemnified Party's duties under the Transaction
     Documents except for any Indemnified Amounts that are conclusively

                                      -10-

          to this Agreement, the Security Agreement, the Loan Note, the Net Loan
          Investment, the Collateral, the obligations hereunder, the funding of
          any purchases, then within 10 days after demand by the Lender, either
          the Borrower or Servicer shall pay to the Lender such additional
          amount or amounts as will compensate such Indemnified Party for such
          increased cost or reduction.

     (b)  The Lender will promptly notify the Borrower and Servicer of any event
          of which it has knowledge, occurring after the date hereof, which will
          entitle an Indemnified Party to compensation pursuant to this Section
          4.2. A notice by the Lender claiming compensation under this Section
          and setting forth the additional amount or amounts to be paid to it
          hereunder shall be conclusive in the absence of manifest error. In
          determining such amount, the Lender may use any reasonable averaging
          and attributing methods.

4.3  Other Costs, Expenses and Related Matters

Each of the Borrower and AmeriCredit Canada agrees, upon receipt of a written
invoice, to pay or cause to be paid, and to save the Lender and the Collateral
Agent harmless against liability for the payment of, all reasonable
out-of-pocket expenses (including, without limitation, all reasonable Legal
Costs, accountants' and other third parties' fees and expenses, any filing fees
and expenses incurred by officers or employees of the Lender) incurred by or on
behalf of the Lender or the Collateral Agent (i) subject to the terms and
conditions of the Fee Letter, in connection with the negotiation, execution,
delivery and preparation of this Agreement, the Loan Note, and the Security
Agreement and any other Transaction Document and the transactions contemplated
hereby and thereby; and (ii) from time to time (a) relating to any amendments,
waivers or consents under this Agreement, the Loan Note, the Security Agreement
and any other Transaction Document, (b) arising in connection with the Lender's,
or its agent's enforcement or preservation of rights (including, without
limitation, the perfection and protection of the Collateral Agent's security
interest in the Collateral), (c) arising in connection with any dispute,
disagreement, litigation or preparation for litigation involving this Agreement
or any other Transaction Document, or (d) arising in connection with any
transfer of Receivables under the Master Receivables Purchase Agreement or the
Servicing Agreement.

4.4  Taxes

Except as otherwise required by applicable law, all payments made hereunder by
the Borrower and AmeriCredit Canada (each a "payor") to the Collateral Agent or
the Lender shall be made free and clear of and without deduction for or on
account of any present or future taxes, fees, duties, withholdings or other
charges of any nature whatsoever imposed by any taxing authority on the
Collateral Agent or the Lender (or any assignee of such party) (such
non-excluded items being called "Taxes"), but excluding any taxes, fees, duties,
withholdings or other charges (i) imposed on or measured by the net income or
capital of the Lender or the Collateral Agent by the jurisdictions under the
laws of which the Lender or the Collateral Agent is organized, is resident or
carries on business or (ii) imposed as a result of a change of residence of the
Lender or the Collateral Agent (or any assignee of such Person) for tax purposes
other than any change of residency of the Lender or the Collateral Agent which
is the result of an assignment by the Lender or the Collateral Agent to an
affiliate of the Lender or the Collateral Agent following the occurrence of a
Termination Event ("Excluded Taxes"). In the event that any withholding or

<PAGE>

                                      -11-

deduction from any payment made by the payor hereunder is required in respect of
any Taxes, then such payor shall:

     (a)  pay directly to the relevant authority the full amount required to be
          so withheld or deducted;

     (b)  promptly forward to the Collateral Agent or the Lender an official
          receipt or other documentation satisfactory to the Collateral Agent or
          the Lender, as applicable, evidencing such payment to such authority;
          and

     (c)  pay to the Collateral Agent or the Lender, as applicable, such
          additional amount or amounts as is necessary to ensure that the net
          amount after payment of all Taxes imposed by any relevant jurisdiction
          on any additional amounts payable under this Section 4.4 actually
          received by the Collateral Agent or the Lender, as applicable, will
          equal the full amount such Collateral Agent or Lender, as applicable,
          would have received had no such withholding or deduction been
          required.

Moreover, if any Taxes are directly asserted against the Collateral Agent or the
Lender, as applicable, with respect to any payment received by the Collateral
Agent or the Lender hereunder, the Collateral Agent or the Lender, as
applicable, may pay such Taxes and the payor will promptly pay such additional
amounts (including any penalties, interest or expenses) as shall be necessary in
order that the net amount received by the recipient after the payment of such
Taxes (including any Taxes on such additional amount) shall equal the amount the
Collateral Agent or the Lender would have received had such Taxes not been
asserted.

If the payor fails to pay any Taxes when due to the appropriate taxing authority
or fails to remit to the Collateral Agent or the Lender, as applicable, the
required receipts or other required documentary evidence, the payor shall
indemnify the Collateral Agent or the Lender, as applicable, for any incremental
Taxes, interest, or penalties that may become payable by the Collateral Agent or
the Lender as applicable, as a result of any such failure.

If the Collateral Agent or the Lender, as applicable, determines that any credit
or deduction received by it is reasonably allocable to any Taxes paid or
reimbursed by the payor under this Section 4.4, the Collateral Agent or the
Lender, as applicable, shall pay the amount of such credit or deduction to the
payor.

4.5  Liability of Seller; Indemnities

     (a)  The Seller (in its capacity as such) shall be liable hereunder only to
          the extent of the obligations in this Agreement and the other
          Transaction Documents specifically undertaken by the Seller and the
          representations made by the Seller herein and therein;

     (b)  The Seller shall indemnify the Trustee and the Collateral Agent, and
          their respective officers, directors, agents and employees against any
          and all loss, liability or expense, (other than overhead and expenses
          incurred in the normal course of business) incurred by each of them in
          connection with the acceptance or administration of the Trust and the
          performance of their duties under the

<PAGE>

                                      -12-

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

     (c)  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 Seller 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 Seller without interest.

     (a)  This Agreement shall be binding on, and inure to the benefit of the
          Borrower and AmeriCredit Canada, and their respective successors and
          assigns; provided, however, that neither AmeriCredit Canada, nor the

          neither the Borrower nor AmeriCredit Canada shall have any obligation
