which they were made when such Prospectus is delivered, not misleading, or, if
for any other reason it shall be necessary during such same period to amend or

the Registration Statement or the Prospectus or any supplement to the Prospectus
that may, in the judgment of the Seller or the Underwriters, be required by the
Securities Act or requested by the Commission.  Neither the Underwriters'
consent to nor their delivery of any such amendment or supplement shall
constitute a waiver of any of the conditions set forth in Section 7 hereof.

          E.  To cause to be furnished to the Underwriters and counsel for the
Underwriters, prior to filing with the Commission, and to obtain the consent of
the Underwriters, which consent will not unreasonably be withheld, for the

the Notes. The Seller will cause the filing of such statements and reports as
may be required by the laws of each jurisdiction in which the Notes have been so
qualified.

          G.  The Seller will not, without the prior written consent of the

management, financial position, shareholders' equity or results of operations of
the Sponsor or the Seller, the Seller will give prompt written notice thereof to
the Underwriters.

or cause to be furnished such documents and take any such other actions.

     and adverse effect on its business or operations.

     court, tribunal or governmental body are currently pending or, to the best
     of such counsel's knowledge, threatened against the Note Insurer, which, if

     Insurance Policy.

          (iii)  The Note Insurance Policy and the Indemnification Agreement
     constitute the irrevocable, valid, legal and binding obligations of the
     Note Insurer in accordance with their respective terms to the extent
     provided therein, enforceable against the Note Insurer in accordance with
     their respective terms, except as the enforceability thereof and the
     availability of particular remedies to enforce the respective terms thereof
     against the Note Insurer may be limited by applicable laws affecting the

     principles of equity.

          (iv) The Note Insurer, as an insurance company, is not eligible for
     relief under the United States Bankruptcy Code.  Any proceedings for the
     liquidation, conservation or rehabilitation of the Note Insurer would be
     governed by the provisions of the Insurance Law of the State of New York.

          (v) The statements set forth in the Prospectus Supplement under the
     captions "The Insurer" and "The Policy" are true and correct, except that
     no opinion is expressed as to financial statements or other financial
     information included in the Prospectus relating to the Note Insurer and,
     insofar as such statements constitute a summary of the Note Insurance
     Policy, accurately and fairly summarize the terms of the Note Insurance
     Policy.

     the meaning of Section 3(a)(8) of the Act.

          (vii)  Neither the execution or delivery by the Note Insurer of the
     Note Insurance Policy or the Indemnification Agreement, nor the performance
     by the Note Insurer of its obligations thereunder, will conflict with any
     provision of the certificate of incorporation or the amended by-laws of the
     Note Insurer nor, to the best of such counsel's knowledge, result in a
     breach of, or constitute a default under, any agreement or other instrument
     to which the Note Insurer is a party or by which any of its property is
     bound nor, to the best of such counsel's knowledge, violate any judgment,
     order or decree applicable to the Note Insurer of any governmental
     regulatory body, administrative agency, court or arbitrator located in any
     jurisdiction in which the Note Insurer is licensed or authorized to do
     business.

     by the Trustee and constitutes a legal, valid and binding obligation of the

     except that as to enforceability such enforcement may (A) be subject to
     applicable bankruptcy, insolvency, reorganization, moratorium or other
     similar laws affecting the rights of creditors generally and (B) be limited
     by general principles of equity (whether considered in a proceeding at law
     or in equity).

          (iv) The Notes have been duly authorized, executed and authenticated
     by the Trustee on the date hereof on behalf of the Trust in accordance with

     any state or federal court or governmental agency or authority is necessary

     reorganization, moratorium or other similar laws affecting the rights of
     creditors generally and (B) be limited by general principles of equity
     (whether considered in a proceeding at law or in equity).

          (iv) The Certificate has been duly authorized, executed and

     upon any of the property or assets of the Owner Trustee pursuant to the
     terms of the articles of association or the by-laws of the Owner Trustee or
     any statute, rule, regulation or order of any governmental agency or body,

     assets or any agreement or instrument known 

                                       20

and hold harmless the Underwriters and each person, if any, who controls the

and against any and all loss, claim, damage or liability, joint or several, or
any action in respect thereof (including, but not limited to, any loss, claim,
damage, liability or action relating to purchases and sales of the Notes), to
which the Underwriters or any such controlling person may become subject, under
the Securities Act or the Exchange Act or otherwise, insofar as such loss,
claim, damage, liability or action arises out of, or is based upon, (i) any
untrue statement or alleged untrue statement of a material fact contained in the
Registration Statement or the Prospectus, (ii) the omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, (iii) any untrue statement or

or documented other expenses reasonably incurred by the Underwriters or such
controlling person in connection with investigating or defending or preparing to
defend against any such loss, claim, damage, liability or action as such
expenses are incurred; provided, however, that the foregoing indemnity with
                       --------  -------                                   
respect to any untrue statement contained in or omission from the Prospectus
shall not inure to the benefit of the Underwriters if the Sponsor shall sustain
the burden of proving that the person asserting against the Underwriters the
loss, liability, claim, damage or expense purchased any of the Notes which are
the subject thereof and was not sent or given a copy of the appropriate
Prospectus (or the appropriate Prospectus as amended or supplemented) (the term
Prospectus as used in this clause shall not include documents incorporated by
reference thereto), if required by law, at or prior to the written confirmation
of the sale of such Notes (unless such Prospectus is amended or supplemented
after the Prospectus has been delivered pursuant to Rule 424(b)) to such person
and the untrue statement contained in or omission from such preliminary
prospectus was corrected in the appropriate Prospectus (or the appropriate
Prospectus as amended or supplemented).

          (y) The Seller agrees to indemnify and hold harmless the Underwriters

Securities Act or the Exchange Act, from and against any and all loss, claim,
damage or liability, joint or several, or any action in respect thereof
(including, but not limited to, any loss, claim, damage, liability or action
relating to purchases and sales of the Notes), to which the Underwriters or any
such controlling person may become subject, under the Securities Act or the
Exchange Act or otherwise, insofar as such loss, claim, damage, liability or
action arises out of, or is based upon, (i) any untrue statement or alleged
untrue statement of a material fact contained in the Seller Offering Materials
or (ii) the omission or alleged omission to state therein a material fact
required to be stated or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading and shall
reimburse the Underwriters and each such controlling person promptly upon demand
for any documented legal or documented other expenses reasonably incurred by the
Underwriters or such controlling person in connection with investigating or
defending or preparing to defend against any such loss, claim, damage, liability
or action as such expenses are incurred; provided, however, that the foregoing
                                         --------  -------                    
indemnity with respect to any untrue statement contained in or omission from a
prospectus shall not inure to the benefit of the Underwriters if the Seller
shall sustain the burden of proving that the person asserting against the
Underwriters the loss, liability, claim, damage or expense purchased any of the
Notes which are the subject thereof and was not sent or given a copy of the
appropriate Prospectus (or the appropriate Prospectus as amended or
supplemented) (the term Prospectus as used in this clause shall not include
documents incorporated by reference thereto), if required by law, at or prior to
the written confirmation of the sale of such Notes to such person and the untrue
statement contained in or omission from such preliminary prospectus was
corrected in the appropriate Prospectus (or the appropriate Prospectus as
amended or supplemented).

          The foregoing indemnity agreement is in addition to any liability
which the Sponsor or the Seller may otherwise have to the Underwriters or any
controlling person of any of the Underwriters.

          B.  Each of the Underwriters agrees to severally and not jointly
indemnify and hold harmless the Sponsor and the Seller, the directors and the
officers of the Sponsor who signed the Registration Statement, and each person,
if any, who controls the Sponsor or the Seller within the meaning of the
Securities Act or the Exchange Act against any and all loss, claim, damage or
liability, or any action in respect thereof, to which the Sponsor, the Seller or
any such director, officer or controlling person may become subject, under the
Securities Act or the Exchange Act or otherwise, insofar as such loss, claim,
damage, liability or action arises out of, or is based upon, (i) any untrue
statement or alleged untrue statement of a material fact relating to such
Underwriter contained in the Underwriter Information or (ii) the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, and shall reimburse the Sponsor or
the Seller, as the case may be, promptly on demand, and any such director,
officer or controlling person for any documented legal or other documented
expenses reasonably incurred by the Sponsor or the Seller, or any director,
officer or controlling person in connection with investigating or defending or
preparing to defend against any such loss, claim, damage, liability or action as

                                       24
<PAGE>
 
          The foregoing indemnity agreement is in addition to any liability
which the Underwriters may otherwise have to the Sponsor or the Seller or any
such director, officer or controlling person.

          C.  Promptly after receipt by any indemnified party under this Section
9 of notice of any claim or the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Section 9, promptly notify the indemnifying party
in writing of the claim or the commencement of that action; provided, however,
that the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Section 9 except to the extent it has
been materially prejudiced by such failure; and provided, further, that the
                                                --------  -------          
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Section 9.

          If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party, unless such indemnified party reasonably objects to such assumption on
the ground that there may be legal defenses available to it which are different
from or in addition to those available to such indemnifying party.  After notice
from the indemnifying party to the indemnified party of its election to assume
the defense of such claim or action, except to the extent provided in the next
following paragraph, the indemnifying party shall not be liable to the
indemnified party under this Section 9 for any fees and expenses of counsel
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation.

          Any indemnified party shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless:  (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel; or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Representative, if the indemnified
parties under this Section 9 consist of the Underwriters or any of their
controlling persons, or by the Companies, if the 

                                       25
<PAGE>
 
indemnified parties under this Section 9 consist of either of the Companies or
any of the Companies' directors, officers or controlling persons, but in either
case reasonably satisfactory to the indemnified party.

          Each indemnified party, as a condition of the indemnity agreements
contained in Sections 9A and B, shall use its best efforts to cooperate with the
indemnifying party in the defense of any such action or claim.  No indemnifying
party shall be liable for any settlement of any such action effected without its
written consent (which consent shall not be unreasonably withheld), but if
settled with its written consent or if there be a final judgment for the
plaintiff in any such action, the indemnifying party agrees to indemnify and
hold harmless any indemnified party from and against any loss or liability by
reason of such settlement or judgment.  No indemnifying party shall, without
prior written consent of the indemnified party, effect any settlement of any
pending or threatened action in respect of which such indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement includes an unconditional release of
such indemnified party from all liability on any claims that are the subject
matter of such action.

          Notwithstanding the foregoing, if (x) the indemnified party has made a
proper request to the indemnifying party for the payment of the indemnified
party's legal fees and expenses, as permitted hereby, and (y) such request for
payment has not been honored within thirty days, then, for so long as such
request thereafter remains unhonored, the indemnifying party shall be liable for
any settlement entered into by the indemnified party whether or not the
indemnifying party consents thereto.

          D.  Each Underwriter agrees to deliver to the Companies no later than
the date prior to the date on which the Form 8-K is required to be filed
pursuant to Section 2(ii) hereof with a copy of its Derived Information (defined
                                                    -------------------         
below) for filing with the Commission on Form 8-K.

          E.  Each Underwriter agrees, assuming all Company-Provided Information
                                                    ----------------------------
(defined below) is accurate and complete in all material respects, to severally
and not jointly indemnify and hold harmless the Sponsor and the Seller, each of
the Sponsor's and the Seller's officers and directors and each person who
controls the Sponsor or the Seller within the meaning of Section 15 of the
Securities Act against any and all losses, claims, damages or liabilities, joint
or several, to which they may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement of a
material fact contained in the Derived Information provided by such Underwriter,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, and agrees to reimburse each such indemnified party for
any legal or other expenses reasonably incurred by him, her or it in connection
with investigating or defending or preparing to defend any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that  in no case shall any Underwriter be responsible for any amount in excess
of the underwriting discount applicable to the Notes purchased by such

                                       26
<PAGE>
 
Underwriter.  The obligations of each of the Underwriters under this Section 9E
shall be in addition to any liability which such Underwriter may otherwise have.

          The procedures set forth in Section 9C shall be equally applicable to
this Section 9E.

          F.  For purposes of this Section 9, the term "Derived Information"
means such portion, if any, of the information delivered to the Sponsor or the
Seller pursuant to Section 9D for filing with the Commission on Form 8-K as:

          (i)  is not contained in the Prospectus without taking into account
               information incorporated therein by reference;

          (ii) does not constitute Company-Provided Information; and

          (iii)   is of the type of information defined as Collateral term
               sheets, Structural term sheets or Computational Materials (as
               such terms are interpreted in the No-Action Letters).

          "Company-Provided Information" means any computer tape furnished to
the Underwriters by the Sponsor or the Seller concerning the Receivables
comprising the Trust.

          The terms "Collateral term sheet" and "Structural term sheet" shall
have the respective meanings assigned to them in the February 13, 1995 letter
(the "PSA Letter") of Cleary, Gottlieb, Steen & Hamilton on behalf of the Public
Securities Association (which letter, and the SEC staff's response thereto, were
publicly available February 17, 1995).  The term "Collateral term sheet" as used
herein includes any subsequent Collateral term sheet that reflects a substantive
change in the information presented.  The term "Computational Materials" has the
meaning assigned to it in the May 17, 1994 letter (the "Kidder letter" and
together with the PSA Letter, the "No-Action Letters") of Brown & Wood on behalf
of Kidder, Peabody & Co., Inc. (which letter, and the SEC staff's response
thereto, were publicly available May 20, 1994).


          G.  If the indemnification provided for in this Section 9 shall for
any reason be unavailable to hold harmless an indemnified party under Section 9A
or B in respect of any loss, claim, damage or liability, or any action in
respect thereof, referred to therein, then each indemnifying party shall, in
lieu of indemnifying such indemnified party, contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability, or action in respect thereof, (i) in such proportion as shall be
appropriate to reflect the relative benefits received by the Sponsor or the
Seller on the one hand and the Underwriters on the other from the offering of
the Notes or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Sponsor or the Seller on the one hand and the Underwriters on the
other with respect to the statements or omissions which resulted in 

                                       27
<PAGE>
 
such loss, claim, damage or liability, or action in respect thereof, as well as
any other relevant equitable considerations.

          The relative benefits of the Underwriters and the Sponsor or the
Seller shall be deemed to be in such proportion so that the Underwriters are
responsible for that portion represented by the percentage that the underwriting
discount appearing on the cover page of the Prospectus bears to the public
offering price appearing on the cover page of the Prospectus.

          The relative fault of the Underwriters and the Sponsor or the Seller
shall be determined by reference to whether the untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact relates to information supplied by the Sponsor or the Seller or by one of
the Underwriters, the intent of the parties and their relative knowledge, access
to information and opportunity to correct or prevent such statement or omission
and other equitable considerations.

          The Sponsor, the Seller and the Underwriters agree that it would not
be just and equitable if contributions pursuant to this Section 9G were to be
determined by pro rata allocation or by any other method of allocation which
does not take into account the equitable considerations referred to herein. The
amount paid or payable by an indemnified party as a result of the loss, claim,
damage or liability, or action in respect thereof, referred to above in this
Section 9G shall be deemed to include, for purposes of this Section 9G, any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.

          Each person, if any, who controls each Underwriter within the meaning
of the Securities Act or the Exchange Act shall have the same rights to
contribution as each of the Underwriters and each director of the Sponsor and/or
the Seller, each officer of the Sponsor who signed the Registration Statement,
and each person, if any, who controls the Sponsor and/or the Seller within the
meaning of the Securities Act or the Exchange Act shall have the same rights to
contribution as the Sponsor.

          In no case shall any Underwriter be responsible for any amount in
excess of the underwriting discount applicable to the Notes purchased by such
Underwriter hereunder.  No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

          H.  The Underwriters severally confirm that the information set forth
(i) in the Prospectus Supplement relating to market making and (ii) under the
caption "Underwriting" in the Prospectus Supplement, together with the Derived
Information, is correct and constitutes the only information furnished in
writing to the Sponsor or the Seller by or on behalf of the Underwriters
specifically for inclusion in the Registration Statement and the Prospectus.

          Section 10.  Default by One or More of the Underwriters.  If one or
                       ------------------------------------------            
more of the Underwriters participating in the public offering of the Notes shall
fail at the 

                                       28
<PAGE>
 
Closing Date to purchase the Notes which it is obligated to purchase hereunder
(the "Defaulted Securities"), then the non-defaulting Underwriter shall have the
right, within 24 hours thereafter, to make arrangements to purchase all, but not
less than all, of the Defaulted Securities in such amounts as may be agreed upon
and upon the terms herein set forth. If, however, the Underwriter have not
completed such arrangements within such 24-hour period, then:

          (i) if the aggregate principal amount of Defaulted Securities does not
exceed 10% of the aggregate principal amount of the Notes to be purchased
pursuant to this Agreement, the non-defaulting Underwriter shall be obligated to
purchase the full amount thereof, or

          (ii) if the aggregate principal amount of Defaulted Securities exceeds
10% of the aggregate principal amount of the Notes to be purchased pursuant to
this Agreement, this Agreement shall terminate, without any liability on the
party of the non- defaulting Underwriter.

          No action taken pursuant to this Section shall relieve the defaulting
Underwriter from the liability with respect to any default of such Underwriter
under this Agreement.

          In the event of a default by either Underwriter as set forth in this
Section, each of the Underwriters and the Seller shall have the right to
postpone the Closing Date for a period not exceeding five Business Days in order
that any required changes in the Registration Statement or Prospectus or in any
other documents or arrangements may be effected.

          Section 11.  Termination.  This Agreement shall be subject to
                       -----------                                     
termination in the absolute discretion of the Representative, by notice given to
the Sponsor and the Seller prior to delivery of and payment for the Notes if
prior to such time (i) any change, or any development involving a prospective
change, in or affecting particularly the business or properties of the Trust,
the Sponsor or the Seller which, in the reasonable judgment of the
Representative, materially impairs the investment quality of the Notes or makes
it impractical or inadvisable to market the Notes; (ii) the Notes have been
placed on credit watch by S&P or Moody's with negative implications; (iii)
trading in securities generally on the New York Stock Exchange or the National
Association of Securities Dealers National Market System shall have been
suspended or limited, or minimum prices shall have been established on such
exchange or market system; (iv) a banking moratorium shall have been declared by
either Federal or New York State authorities; or (v) there shall have occurred
any outbreak or material escalation of hostilities or other calamity or crisis,
the effect of which makes it, in the reasonable judgment of the Representative,
impractical or inadvisable to proceed with the completion of the sale and
payment for the Notes.  Upon such notice being given, the parties to this
Agreement shall (except for any liability arising before or in relation to such
termination) be released and discharged from their respective obligations under
this Agreement.

time may not exceed such amounts except as provided in Section 2.5.

               The Notes shall be issuable as registered Notes in the minimum
denomination of $1,000 and in integral multiples thereof (except for one Note of
each class which may be issued in a denomination other than an integral multiple
of $1,000).

               No Note shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose, unless there appears on such Note a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized
signatories, and such certificate upon any Note shall be conclusive evidence,
and the only evidence, that such Note has been duly authenticated and delivered
hereunder.

               SECTION 2.3 Temporary Notes. Pending the preparation of
Definitive Notes, the Issuer may execute, and upon receipt of an Issuer Order
the Trustee shall authenticate and deliver, temporary Notes which are printed,
lithographed, typewritten, mimeographed or otherwise produced, of the tenor of
the Definitive Notes in lieu of which they are issued and with such variations
not inconsistent with the terms of this Indenture as the officers executing such
Notes may determine, as evidenced by their execution of such Notes.

               If temporary Notes are issued, the Issuer will cause Definitive
Notes to be prepared without unreasonable delay. After the preparation of
Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes
upon surrender of the temporary Notes at the office or agency of the Issuer to
be maintained as provided in Section 3.2, without charge to the Noteholder. Upon
surrender for cancellation of any one or more temporary Notes, the Issuer shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
like principal amount of Definitive Notes of authorized denominations. Until so
exchanged, the temporary Notes shall in all respects be entitled to the same
benefits under this Indenture as Definitive Notes.

               SECTION 2.4 Registration; Registration of Transfer and Exchange.
The Issuer shall cause to be kept a register (the "Note Register") in which,
subject to such reasonable regulations as it may prescribe, the Issuer shall
provide for the registration of Notes and the registration of transfers of
Notes. The Trustee shall be "Note Registrar" for the purpose of registering
Notes and transfers of Notes as herein provided. Upon any resignation of any
Note Registrar, the Issuer shall promptly appoint a successor or, if it elects
not to make such an appointment, assume the duties of Note Registrar.

               If a Person other than the Trustee is appointed by the Issuer as
Note Registrar, the Issuer will give the Trustee prompt written notice of the
appointment of such Note Registrar and of the location, and any change in the
location, of the Note Register, and the Trustee shall have the right to inspect
the Note Register at all reasonable times and to obtain copies thereof, and the
Trustee shall have the right to conclusively rely upon a certificate executed on
behalf of the Note Registrar by an Executive Officer thereof as to the names and
addresses of the Noteholders of the Notes and the principal amounts and number
of such Notes.

               Subject to Sections 2.10 and 2.12 hereof, upon surrender for
registration of transfer of any Note at the office or agency of the Issuer to be
maintained as provided in Section 3.2, if the requirements of Section 8-401(1)
of the UCC are met the Issuer shall execute and upon its request the Trustee
shall authenticate and the Noteholder shall obtain from the Trustee, in the name
of the designated transferee or transferees, one or more new Notes, in any
authorized denominations, of the same class and a like aggregate principal
amount.

               At the option of the Noteholder, Notes may be exchanged for other
Notes in any authorized denominations, of the same class and a like aggregate
principal amount, upon surrender of the Notes to be exchanged at such office or
agency. Whenever any Notes are so surrendered for exchange, subject to Sections
2.10 and 2.12 hereof, if the requirements of Section 8-401(1) of the UCC are met
the Issuer shall execute and upon its request the Trustee shall authenticate and
the Noteholder shall obtain from the Trustee, the Notes which the Noteholder
making the exchange is entitled to receive.

               All Notes issued upon any registration of transfer or exchange of
Notes shall be the valid obligations of the Issuer, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

               Every Note presented or surrendered for registration of transfer
or exchange shall be (i) duly endorsed by, or be accompanied by a written
instrument of transfer in the form attached to Exhibits A-1, A-2, A-3, A-4 and
A-5 duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing, with such signature guaranteed by an "eligible guarantor
institution" meeting the requirements of the Note Registrar which requirements
include membership or participation in Securities Transfer Agents Medallion
Program ("Stamp") or such other "signature guarantee program" as may be
determined by the Note Registrar in addition to, or in substitution for, Stamp,
all in accordance with the Exchange Act, and (ii) accompanied by such other
documents as the Trustee may require.

               Notwithstanding the foregoing, in the case of any sale or other
transfer of a Definitive Note, the transferor of such Definitive Note shall be
required to represent and warrant in writing that the prospective transferee
either (a) is not (i) an employee benefit plan (as defined in section 3(3) of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA")),
which is subject to the provisions of Title I of ERISA, (ii) a plan (as defined
in section 4975(e)(1) of the Code), which is subject to Section 4975 of the
Code, or (iii) an entity whose underlying assets are deemed to be assets of a
plan described in (i) or (ii) above by reason of such plan's investment in the
entity (any such entity described in clauses (i) through (iii), a "Benefit Plan
Entity") or (b) is a Benefit Plan Entity and the acquisition and holding of the
Definitive Note by such prospective transferee is covered by a Department of
Labor Prohibited Transaction Class Exemption. Each transferee of a Book Entry
Note that is a Benefit Plan Entity shall be deemed to represent that its
acquisition and holding of the Book Entry Note is covered by a Department of
Labor Prohibited Transaction Class Exemption.

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

                                       14
<PAGE>
 
transfer or exchange of Notes, other than exchanges pursuant to Section 2.3 or
9.6 not involving any transfer.

               The preceding provisions of this section notwithstanding, the
Issuer shall not be required to make and the Note Registrar shall not register
transfers or exchanges of Notes selected for redemption or of any Note for a
period of 15 days preceding the due date for any payment with respect to the
Note.

               SECTION 2.5 Mutilated, Destroyed, Lost or Stolen Notes. If (i)
any mutilated Note is surrendered to the Trustee, or the Trustee receives
evidence to its satisfaction of the destruction, loss or theft of any Note, and
(ii) there is delivered to the Trustee and the Security Insurer (unless an
Insurer Default shall have occurred and be continuing) such security or
indemnity as may be required by it to hold the Issuer, the Trustee and the
Security Insurer harmless, then, in the absence of notice to the Issuer, the
Note Registrar or the Trustee that such Note has been acquired by a bona fide
purchaser, and provided that the requirements of Section 8-405 of the UCC are
met, the Issuer shall execute and upon its request the Trustee shall
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Note, a replacement Note; provided, however, that if
any such destroyed, lost or stolen Note, but not a mutilated Note, shall have
become or within seven days shall be due and payable, or shall have been called
for redemption, instead of issuing a replacement Note, the Issuer may direct the
Trustee, in writing, to pay such destroyed, lost or stolen Note when so due or
payable or upon the Redemption Date without surrender thereof. If, after the
delivery of such replacement Note or payment of a destroyed, lost or stolen Note
pursuant to the proviso to the preceding sentence, a bona fide purchaser of the
original Note in lieu of which such replacement Note was issued presents for
payment such original Note, the Issuer, the Trustee and the Security Insurer
shall be entitled to recover such replacement Note (or such payment) from the
Person to whom it was delivered or any Person taking such replacement Note from
such Person to whom such replacement Note was delivered or any assignee of such
Person, except a bona fide purchaser, and shall be entitled to recover upon the
security or indemnity provided therefor to the extent of any loss, damage, cost
or expense incurred by the Issuer or the Trustee in connection therewith.

               Upon the issuance of any replacement Note under this Section, the
Issuer may require the payment by the Holder of such Note of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other reasonable expenses (including the fees and expenses of
the Trustee) connected therewith.

               Every replacement Note issued pursuant to this Section in
replacement of any mutilated, destroyed, lost or stolen Note shall constitute an
original additional contractual obligation of the Issuer, whether or not the
mutilated, destroyed, lost or stolen Note shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder.

               The provisions of this Section are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Notes.

               SECTION 2.6 Persons Deemed Owner. Prior to due presentment for
registration of transfer of any Note, the Issuer, the Trustee and any agent of
Issuer, the Trustee, the Security Insurer may treat the Person in whose name any
Note is registered (as of the Record Date) as the owner of such Note for the
purpose of receiving payments of principal of and interest, if any on such Note
and for all other purposes whatsoever, whether or not such Note be overdue, and
none of the Issuer, the Security Insurer, the Trustee nor any agent of the
Issuer or the Trustee shall be affected by notice to the contrary.

               SECTION 2.7 Payment of Principal and Interest; Defaulted
Interest.

               (a) The Notes shall accrue interest as provided in the forms of 
the Class A-1 Note, the Class A-2 Note, the Class A-3 Note, the Class A-4 Note
and the Class A-5 Note set forth in Exhibits A-1, A-2, A-3, A-4 and A-5,
respectively, and such interest shall be due and payable on each Distribution
Date and each Insured Distribution Date, as specified therein. Any installment
of interest or principal, if any, payable on any Note which is punctually paid
or duly provided for by the Issuer on the applicable Distribution Date or
Insured Distribution Date shall be paid to the Person in whose name such Note
(or one or more Predecessor Notes) is registered on the Record Date, by check
mailed first-class, postage prepaid, to such Person's address as it appears on
the Note Register on such Record Date, except that, unless Definitive Notes have
been issued pursuant to Section 2.12, with respect to Notes registered on the
Record Date in the name of the nominee of the Clearing Agency (initially, such
nominee to be Cede & Co.), payment will be made by wire transfer in immediately
available funds to the account designated by such nominee and except for the
final installment of principal payable with respect to such Note on a
Distribution Date or Insured Distribution Date or on the Final Scheduled
Distribution Date (or the Insured Distribution Date which immediately follows
such Final Scheduled Distribution Date)(and except for the Redemption Price for
any Note called for redemption pursuant to Section 10.1(a)) which shall be
payable as provided below. The funds represented by any such checks returned
undelivered shall be held in accordance with Section 3.3.

               (b) The principal of each Note shall be payable in installments 
on each Distribution Date or Insured Distribution Date, as applicable, as
provided in the forms of the Class A-1 Note, the Class A-2 Note, the Class A-3
Note, the Class A-4 Note and the Class A-5 Note set forth in Exhibits A-1, A-2,
A-3, A-4 and A-5, respectively. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes shall be due and payable, if not previously paid,
on the date on which an Event of Default shall have occurred and be continuing,
if the Trustee or the Noteholders representing not less than a majority of the
Outstanding Amount of the Notes have declared the Notes to be immediately due
and payable in the manner provided in Section 5.2. All principal payments on
each class of Notes shall be made pro rata to the Noteholders of such class
entitled thereto. Upon written notice from the Issuer, the Trustee shall notify
the Person in whose name a Note is registered at the close of business on the
Record Date preceding the Distribution Date on which the Issuer expects that the
final installment of principal of and interest on such Note will be paid. Such
notice shall be mailed or transmitted by facsimile prior to such final
Distribution Date and shall specify that such final installment will be payable
only upon presentation and surrender of such Note and shall specify the place
where such Note may be presented and surrendered for payment of such
installment. Notices in connection with redemptions of Notes shall be mailed to
Noteholders as provided in Section 10.2. 

                                       16
<PAGE>
 
               (c) If the Issuer defaults in a payment of interest on the 
Notes, and such default is waived by the Controlling Party, the Issuer shall pay
defaulted interest (plus interest on such defaulted interest to the extent
lawful) at the applicable Interest Rate in any lawful manner. The Issuer may pay
such defaulted interest to the Persons who are Noteholders on the immediately
following Insured Distribution Date, and, if such amount is not paid on such
following Insured Distribution Date, then on a subsequent special record date,
which date shall be at least five Business Days prior to the payment date. The
Issuer shall fix or cause to be fixed any such special record date and payment
date, and, at least 15 days before any such special record date, the Issuer
shall mail to each Noteholder and the Trustee a notice that states the special
record date, the payment date and the amount of defaulted interest to be paid.

               (d) Promptly following the date on which all principal of and 
interest on the Notes has been paid in full and the Notes have been surrendered
to the Trustee, the Trustee shall, if the Security Insurer has paid any amount
in respect of the Notes under the Note Policy or otherwise which has not been
reimbursed to it, deliver such surrendered Notes to the Security Insurer.

               SECTION 2.8 Cancellation. Subject to Section 2.7(d), all Notes
surrendered for payment, registration of transfer, exchange or redemption shall,
if surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by the Trustee. Subject to Section 2.7(d), the
Issuer may at any time deliver to the Trustee for cancellation any Notes
previously authenticated and delivered hereunder which the Issuer may have
acquired in any manner whatsoever, and all Notes so delivered shall be promptly
canceled by the Trustee. No Notes shall be authenticated in lieu of or in
exchange for any Notes canceled as provided in this Section, except as expressly
permitted by this Indenture. Subject to Section 2.7(d), all canceled Notes may
be held or disposed of by the Trustee in accordance with its standard retention
or disposal policy as in effect at the time unless the Issuer shall timely
direct by an Issuer Order that they be destroyed or returned to it; provided
that such Issuer Order is timely and the Notes have not been previously disposed
of by the Trustee.

               SECTION 2.9 Release of Collateral. The Trust Collateral Agent
shall, on or after the Termination Date, release any remaining portion of the
Trust Estate from the lien created by this Indenture and deposit in the
Collection Account any funds then on deposit in any other Trust Account. The
Trust Collateral Agent shall release property from the lien created by this
Indenture pursuant to this Section 2.9 only upon receipt of an Issuer Request
accompanied by an Officer's Certificate, an Opinion of Counsel and (if required
by the TIA) Independent Certificates in accordance with TIA ss.ss. 314(c) and
314(d)(1) meeting the applicable requirements of Section 11.1.

               SECTION 2.10 Book-Entry Notes. The Notes, upon original issuance,
will be issued in the form of typewritten Notes representing the Book-Entry
Notes, to be delivered to The Depository Trust Company, the initial Clearing
Agency, by, or on behalf of, the Issuer. Such Notes shall initially be
registered on the Note Register in the name of Cede & Co., the nominee of the
initial Clearing Agency, and no Note Owner will receive a Definitive Note
representing such Note Owner's interest in such Note, except as provided in
Section 2.12. Unless and until definitive, fully registered Notes (the
"Definitive Notes") have been issued to Note Owners pursuant to Section 2.12:

                                       17
<PAGE>
 
                    (i)    the provisions of this Section shall be in full force
               and effect;

                    (ii)   the Note Registrar and the Trustee shall be entitled
               to deal with the Clearing Agency for all purposes of this
               Indenture (including the payment of principal of and interest on
               the Notes and the giving of instructions or directions hereunder)
               as the sole Holder of the Notes, and shall have no obligation to
               the Note Owners;

                    (iii)  to the extent that the provisions of this Section
               conflict with any other provisions of this Indenture, the
               provisions of this Section shall control; 

                    (iv)   the rights of Note Owners shall be exercised only
               through the Clearing Agency and shall be limited to those
               established by law and agreements between such Note Owners and
               the Clearing Agency and/or the Clearing Agency Participants.
               Unless and until Definitive Notes are issued pursuant to Section
               2.12, the initial Clearing Agency will make book-entry transfers
               among the Clearing Agency Participants and receive and transmit
               payments of principal of and interest on the Notes to such
               Clearing Agency Participants; 

                    (v)    whenever this Indenture requires or permits actions
               to be taken based upon instructions or directions of Noteholders
               evidencing a specified percentage of the Outstanding Amount of
               the Notes, the Clearing Agency shall be deemed to represent such
               percentage only to the extent that it has received instructions
               to such effect from Note Owners and/or Clearing Agency
               Participants owning or representing, respectively, such required
               percentage of the beneficial interest in the Notes and has
               delivered such instructions to the Trustee; and

                    (vi)   Note Owners may receive copies of any reports sent to
               Noteholders pursuant to this Indenture, upon written request,
               together with a certification that they are Note Owners and
               payment of reproduction and postage expenses associated with the
               distribution of such reports, from the Trustee at the Corporate
               Trust Office.

               SECTION 2.11 Notices to Clearing Agency. Whenever a notice or
other communication to the Noteholders is required under this Indenture, unless
and until Definitive Notes shall have been issued to Note Owners pursuant to
Section 2.12, the Trustee shall give all such notices and communications
specified herein to be given to the Noteholders to the Clearing Agency, and
shall have no obligation to the Note Owners.

               SECTION 2.12 Definitive Notes. If (i) the Servicer advises the
Trustee in writing that the Clearing Agency is no longer willing or able to
properly discharge its responsibilities with respect to the Notes, and the
Servicer is unable to locate a qualified successor, (ii) the Servicer at its
option advises the Trustee in writing that it elects to terminate the book-entry
system through the Clearing Agency or (iii) after the occurrence of an Event of
Default, Note Owners representing beneficial interests aggregating at least a
majority of the Outstanding Amount of the Notes advise the Trustee through the
Clearing Agency in writing that the continuation of a book entry system through
the Clearing Agency is no longer in the best 

                                       18
<PAGE>
 
interests of the Note Owners, then the Clearing Agency shall notify all Note
Owners and the Trustee of the occurrence of any such event and of the
availability of Definitive Notes to Note Owners requesting the same. Upon
surrender to the Trustee of the typewritten Note or Notes representing the Book-
Entry Notes by the Clearing Agency, accompanied by registration instructions,
the Issuer shall execute and the Trustee shall authenticate the Definitive Notes
in accordance with the instructions of the Clearing Agency. None of the Issuer,
the Note Registrar or the Trustee shall be liable for any delay in delivery of
such instructions and may conclusively rely on, and shall be fully protected in
relying on, such instructions. Upon the issuance of Definitive Notes, the
Trustee shall recognize the Holders of the Definitive Notes as Noteholders.

                                  ARTICLE III

                                   Covenants

               SECTION 3.1 Payment of Principal and Interest. The Issuer will
duly and punctually pay the principal of and interest on the Notes in accordance
with the terms of the Notes and this Indenture. Without limiting the foregoing,
the Issuer will cause to be distributed all amounts on deposit in the Note
Distribution Account on a Distribution Date deposited therein pursuant to the
Sale and Servicing Agreement (i) for the benefit of the Class A-l Notes, to
Class A-1 Noteholders, (ii) for the benefit of the Class A-2 Notes, to Class A-2
Noteholders, (iii) for the benefit of the Class A-3 Notes, to Class A-3
Noteholders, (iv) for the benefit of the Class A-4 Notes, to Class A-4
Noteholders, and (v) for the benefit of the Class A-5 Notes, to Class A-5
Noteholders. Amounts properly withheld under the Code by any Person from a
payment to any Noteholder of interest and/or principal shall be considered as
having been paid by the Issuer to such Noteholder for all purposes of this
Indenture.

               SECTION 3.2 Maintenance of Office or Agency. The Issuer will
maintain in Columbus, Ohio, an office or agency where Notes may be surrendered
for registration of transfer or exchange, and where notices and demands to or
upon the Issuer in respect of the Notes and this Indenture may be served. The
Issuer hereby initially appoints the Trustee to serve as its agent for the
foregoing purposes. The Issuer will give prompt written notice to the Trustee of
the location, and of any change in the location, of any such office or agency.
If at any time the Issuer shall fail to maintain any such office or agency or
shall fail to furnish the Trustee with the address thereof, such surrenders,
notices and demands may be made or served at the Corporate Trust Office, and the
Issuer hereby appoints the Trustee as its agent to receive all such surrenders,
notices and demands.

               SECTION 3.3 Money for Payments to be Held in Trust. On or before
each Distribution Date, Insured Distribution Date and Redemption Date, the
Issuer shall deposit or cause to be deposited in the Note Distribution Account
from the Collection Account an aggregate sum sufficient to pay the amounts then
becoming due under the Notes, such sum to be held in trust for the benefit of
the Persons entitled thereto and (unless the Note Paying Agent is the Trustee)
shall promptly notify the Trustee of its action or failure so to act.

               The Issuer will cause each Note Paying Agent other than the 
Trustee to execute and deliver to the Trustee and the Security Insurer an
instrument in which such Note Paying 

                                       19
<PAGE>
 
Agent shall agree with the Trustee (and if the Trustee acts as Note Paying
Agent, it hereby so agrees), subject to the provisions of this Section, that
such Note Paying Agent will:

                    (i)    hold all sums held by it for the payment of amounts
               due with respect to the Notes in trust for the benefit of the
               Persons entitled thereto until such sums shall be paid to such
               Persons or otherwise disposed of as herein provided and pay such
               sums to such Persons as herein provided;

                    (ii)   give the Trustee notice of any default by the Issuer
               (or any other obligor upon the Notes) of which it has actual
               knowledge in the making of any payment required to be made with
               respect to the Notes;

                    (iii)  at any time during the continuance of any such
               default, upon the written request of the Trustee, forthwith pay
               to the Trustee all sums so held in trust by such Paying Agent;

                    (iv)   immediately resign as a Note Paying Agent and
               forthwith pay to the Trustee all sums held by it in trust for the
               payment of Notes if at any time it ceases to meet the standards
               required to be met by a Note Paying Agent at the time of its
               appointment; and

                    (v)    comply with all requirements of the Code with respect
               to the withholding from any payments made by it on any Notes of
               any applicable withholding taxes imposed thereon and with respect
               to any applicable reporting requirements in connection therewith.

     The Issuer may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, by Issuer Order direct
any Note Paying Agent to pay to the Trustee all sums held in trust by such Note
Paying Agent, such sums to be held by the Trustee upon the same trusts as those
upon which the sums were held by such Note Paying Agent; and upon such a payment
by any Note Paying Agent to the Trustee, such Note Paying Agent shall be
released from all further liability with respect to such money.

     Subject to applicable laws with respect to the escheat of funds, any money
held by the Trustee or any Note Paying Agent in trust for the payment of any
amount due with respect to any Note and remaining unclaimed for two years after
such amount has become due and payable shall be discharged from such trust and
be paid to the Issuer on Issuer Request with the consent of the Security Insurer
(unless an Insurer Default shall have occurred and be continuing) and shall be
deposited by the Trustee in the Collection Account; and the Holder of such Note
shall thereafter, as an unsecured general creditor, look only to the Issuer for
payment thereof (but only to the extent of the amounts so paid to the Issuer),
and all liability of the Trustee or such Note Paying Agent with respect to such
trust money shall thereupon cease; provided, however, that if such money or any
portion thereof had been previously deposited by the Security Insurer or the
Trust Collateral Agent with the Trustee for the payment of principal or interest
on the Notes, to the extent any amounts are owing to the Security Insurer, such

provisions of Section 3.10, the Issuer will keep in full effect its existence,
rights and franchises as a business trust under the laws of the State of

organized under the laws of any other state or of the United States of America,
in which case the Issuer will keep in full effect its existence, rights and
franchises under the laws of such other jurisdiction) and will obtain and
preserve its qualification to do business in each jurisdiction in which such

Secured Parties to be prior to all other liens in respect of the Trust Estate,

of the Trust Collateral Agent, for the benefit of the Issuer Secured Parties, a
first lien on and a first priority, perfected security interest in the Trust
Estate. The Issuer will from time to time prepare (or shall cause to be

                    (ii)   maintain or preserve the lien and security interest

                    (vi)   pay all taxes or assessments levied or assessed upon
               the Trust Estate when due. 

The Issuer hereby designates the Trust Collateral Agent its agent and attorney-

instrument required by the Trust Collateral Agent pursuant to this Section.

               SECTION 3.6 Opinions as to Trust Estate.

               SECTION 3.7 Performance of Obligations; Servicing of Receivables.

               (a) The Issuer will not take any action and will use its best 
efforts not to permit any action to be taken by others that would release any
Person from any of such Person's material covenants or obligations under any
instrument or agreement included in the Trust Estate or that would result in the
amendment, hypothecation, subordination, termination or discharge of, or impair
the validity or effectiveness of, any such instrument or agreement, except as
ordered by any bankruptcy or other court or as expressly provided in this
Indenture, the Basic Documents or such other instrument or agreement.

               (b) The Issuer may contract with other Persons acceptable to the
Security Insurer (so long as no Insurer Default shall have occurred and be
continuing) to assist it in performing its duties under this Indenture, and any
performance of such duties by a Person

<PAGE>
 
identified to the Trustee and the Security Insurer in an Officer's Certificate

duties under this Indenture.

               (c) The Issuer will punctually perform and observe all of its 
obligations and agreements contained in this Indenture, the Basic Documents and

not limited to, preparing (or causing to prepared) and filing (or causing to be
filed) all UCC financing statements and continuation statements required to be
filed by the terms of this Indenture and the Sale and Servicing Agreement in
accordance with and within the time periods provided for herein and therein.
Except as otherwise expressly provided therein, the Issuer shall not waive,
amend, modify, supplement or terminate any Basic Document or any provision
thereof without the consent of the Trustee, the Security Insurer or the Holders
of at least a majority of the Outstanding Amount of the Notes.

               (d) If a responsible officer of the Owner Trustee shall have 
actual knowledge of the occurrence of a Servicer Termination Event under the
Sale and Servicing Agreement, the Issuer shall promptly notify the Trustee, the
Security Insurer and the Rating Agencies thereof in accordance with Section
11.4, and shall specify in such notice the action, if any, the Issuer is taking
in respect of such default. If a Servicer Termination Event shall arise from the
failure of the Servicer to perform any of its duties or obligations under the
Sale and Servicing Agreement with respect to the Receivables, the Issuer shall
take all reasonable steps available to it to remedy such failure.

               (e) The Issuer agrees that it will not waive timely performance
or observance by the Servicer or the Seller of their respective duties under the
Basic Documents (x) without the prior consent of the Security Insurer (unless an

thereof would adversely affect the Holders of the Notes.

Outstanding, the Issuer shall not:

               do so by the Controlling Party;

                    (ii)   claim any credit on, or make any deduction from the
               principal or interest payable in respect of, the Notes (other
               than amounts properly withheld from such payments under the Code)
               or assert any claim against any present or former Noteholder by
               reason of the payment of the taxes levied or assessed upon any
               part of the Trust Estate; or

                    (iii)  (A) permit the validity or effectiveness of this
               Indenture to be impaired, or permit the lien in favor of the
               Trust Collateral Agent created by this Indenture to be amended,
               hypothecated, subordinated, terminated or discharged, or permit
               any Person to be released from any covenants or obligations with

<PAGE>
 
               respect to the Notes under this Indenture except as may be
               expressly permitted hereby, (B) permit any lien, charge, excise,
               claim, security interest, mortgage or other encumbrance (other
               than the lien of this Indenture) to be created on or extend to or
               otherwise arise upon or burden the Trust Estate or any part
               thereof or any interest therein or the proceeds thereof (other
               than tax liens, mechanics' liens and other liens that arise by
               operation of law, in each case on a Financed Vehicle and arising
               solely as a result of an action or omission of the related
               Obligor), (C) permit the lien of this Indenture not to constitute
               a valid first priority (other than with respect to any such tax,
               mechanics' or other lien) security interest in the Trust Estate
               or (D) amend, modify or fail to comply with the provisions of the
               Basic Documents without the prior written consent of the

               called for redemption pursuant to Section 10.1(a)), as the case
               may be;

               (B) the Issuer has paid or caused to be paid all Insurer Issuer

          firm of certified public accountants, each meeting the applicable
          requirements of Section 11.1(a) and each stating that all conditions
          precedent herein provided for relating to the satisfaction and

                                   Remedies

               SECTION 5.1 Events of Default. "Event of Default", wherever used
herein, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                    (i)   default in the payment of any interest on any Note
               when the same becomes due and payable, and such default shall
               continue for a period of five days (solely for purposes of this
               clause, (x) a payment due on a Distribution Date shall not be
               considered "due" until the immediately following Insured
               Distribution Date and (y) a payment on the Notes funded by the
               Security Insurer or the Collateral Agent pursuant to the Spread
               Account Agreement shall be deemed to be a payment made by the
               Issuer); or

                    (ii)  default in the payment of the principal of or any
               installment of the principal of any Note when the same becomes
               due and payable (solely for purposes of this clause, (x) a
               payment due on a Distribution Date shall not be considered "due"
               until the immediately following Insured Distribution Date and (y)
               a payment on the Notes funded by the Security Insurer or the
               Collateral Agent pursuant to the Spread Account Agreement, shall
               be deemed to be a payment made by the Issuer); or 

                    (iii) so long as an Insurer Default shall not have occurred
               and be continuing, an Insurance Agreement Indenture Cross Default
               shall have occurred; provided, however, that the occurrence of an
               Insurance Agreement Cross Default may not form the basis of an
               Event of Default unless the Security Insurer shall, upon prior
               written notice to the Rating Agencies, have delivered to the
               Issuer and the Trustee and not rescinded a written notice
               specifying that such Insurance Agreement Indenture Cross Default
               constitutes an Event of Default under the Indenture; or 

                    (iv)  so long as an Insurer Default shall have occurred and
               be continuing, default in the observance or performance of any
               covenant or agreement of the Issuer made in this Indenture (other
               than a covenant or agreement, a default in the observance or
               performance of which is elsewhere in this Section specifically
               dealt with), or any representation or warranty of the Issuer made
               in this Indenture or in any certificate or other writing
               delivered pursuant hereto or in connection herewith proving to
               have been incorrect in any material respect as of the time when
               the same shall have been made, and such default shall continue or
               not be cured, or the circumstance or condition in respect

                                       30
<PAGE>
 
               of which such misrepresentation or warranty was incorrect shall
               not have been eliminated or otherwise cured, for a period of 30
               days (or for such longer period, not in excess of 90 days, as may
               be reasonably necessary to remedy such default; provided that
               such default is capable of remedy within 90 days or less and the
               Servicer on behalf of the Owner Trustee delivers an Officer's
               Certificate to the Trustee to the effect that the Issuer has
               commenced, or will promptly commence and diligently pursue, all
               reasonable efforts to remedy such default) after there shall have
               been given, by registered or certified mail, to the Issuer by the
               Trustee or to the Issuer and the Trustee by the Holders of at
               least 25% of the Outstanding Amount of the Notes, a written
               notice specifying such default or incorrect representation or
               warranty and requiring it to be remedied and stating that such
               notice is a "Notice of Default" hereunder; or

                    (v)   so long as an Insurer Default shall have occurred and
               be continuing, the filing of a decree or order for relief by a
               court having jurisdiction in the premises in respect of the
               Issuer or any substantial part of the Trust Estate in an
               involuntary case under any applicable federal or State
               bankruptcy, insolvency or other similar law now or hereafter in
               effect, or appointing a receiver, liquidator, assignee,
               custodian, trustee, sequestrator or similar official of the
               Issuer or for any substantial part of the Trust Estate, or
               ordering the winding-up or liquidation of the Issuer's affairs,
               and such decree or order shall remain unstayed and in effect for
               a period of 60 consecutive days; or

                    (vi)  so long as an Insurer Default shall have occurred and
               be continuing, the commencement by the Issuer of a voluntary case
               under any applicable federal or State bankruptcy, insolvency or
               other similar law now or hereafter in effect, or the consent by
               the Issuer to the entry of an order for relief in an involuntary
               case under any such law, or the consent by the Issuer to the
               appointment or taking possession by a receiver, liquidator,
               assignee, custodian, trustee, sequestrator or similar official of
               the Issuer or for any substantial part of the Trust Estate, or
               the making by the Issuer of any general assignment for the
               benefit of creditors, or the failure by the Issuer generally to
               pay its debts as such debts become due, or the taking of action
               by the Issuer in furtherance of any of the foregoing.

               The Issuer shall deliver to the Trustee and the Security Insurer,
within five days after the occurrence thereof, written notice in the form of an
Officer's Certificate of any event which with the giving of notice and the lapse
of time would become an Event of Default under clause (iii), its status and what
action the Issuer is taking or proposes to take with respect thereto.

               SECTION 5.2 Rights Upon Event of Default.

               (a) If an Insurer Default shall not have occurred and be
continuing and an Event of Default shall have occurred and be continuing, the
Notes shall become immediately due and payable at par, together with accrued
interest thereon. If an Event of Default shall have occurred and be continuing,
the Controlling Party may exercise any of the remedies specified in Section
5.4(a). In the event of any acceleration of any Notes by operation of this
Section 5.2, the 

                                       31
<PAGE>
 
Trustee shall continue to be entitled to make claims under the Note Policy
pursuant to the Sale and Servicing Agreement for Guaranteed Distributions on the
Notes. Payments under the Note Policy following acceleration of any Notes shall
be applied by the Trustee:

               FIRST:  to Noteholders for amounts due and unpaid on the Notes
          for interest, ratably, without preference or priority of any kind,
          according to the amounts due and payable on the Notes for interest;
          and

               SECOND: to Noteholders for amounts due and unpaid on the Notes
          for principal, ratably, without preference or priority of any kind,
          according to the amounts due and payable on the Notes for principal.

               (b) In the event any Notes are accelerated due to an Event of
Default, the Security Insurer shall have the right (in addition to its
obligation to pay Guaranteed Distributions on the Notes in accordance with the
Note Policy), but not the obligation, to make payments under the Note Policy or
otherwise of interest and principal due on such Notes, in whole or in part, on
any date or dates following such acceleration as the Security Insurer, in its
sole discretion, shall elect.

               (c) If an Insurer Default shall have occurred and be continuing 
and an Event of Default shall have occurred and be continuing, the Trustee in
its discretion may, or if so requested in writing by Holders holding Notes
representing not less than a majority of the Outstanding Amount of the Notes,
declare by written notice to the Issuer that the Notes become, whereupon they
shall become, immediately due and payable at par, together with accrued interest
thereon. 

               (d) If an Insurer Default shall have occurred and be continuing,
then at any time after such declaration of acceleration of maturity has been
made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article V provided, the
Noteholders representing a majority of the Outstanding Amount of the Notes, by
written notice to the Issuer and the Trustee, may rescind and annul such
declaration and its consequences if: 

                   (i) the Issuer has paid or deposited with the Trustee a sum
               sufficient to pay:

                         (A) all payments of principal of and interest on all
                    Notes and all other amounts that would then be due hereunder
                    or upon such Notes if the Event of Default giving rise to
                    such acceleration had not occurred; and

                         (B) all sums paid or advanced by the Trustee hereunder
                    and the reasonable compensation, expenses, disbursements and
                    advances of the Trustee and its agents and counsel; and 

                    (ii) all Events of Default, other than the nonpayment of the
               principal of the Notes that has become due solely by such
               acceleration, have been cured or waived as provided in Section
               5.12.

                                       32
<PAGE>
 
               No such rescission shall affect any subsequent default or impair
any right consequent thereto.

               SECTION 5.3 Collection of Indebtedness and Suits for Enforcement
by Trustee.

               (a) The Issuer covenants that if (i) default is made in the 
payment of any interest on any Note when the same becomes due and payable, and
such default continues for a period of five days, or (ii) default is made in the
payment of the principal of or any installment of the principal of any Note when
the same becomes due and payable, the Issuer will pay to the Trustee, for the
benefit of the Holders of the Notes, the whole amount then due and payable on
such Notes for principal and interest, with interest upon the overdue principal,
and, to the extent payment at such rate of interest shall be legally
enforceable, upon overdue installments of interest, at the applicable Interest
Rate and in addition thereto such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee and its agents and counsel.

               (b) Each Issuer Secured Party hereby irrevocably and 
unconditionally appoints the Controlling Party as the true and lawful
attorney-in-fact of such Issuer Secured Party for so long as such Issuer Secured
Party is not the Controlling Party, with full power of substitution, to execute,
acknowledge and deliver any notice, document, certificate, paper, pleading or
instrument and to do in the name of the Controlling Party as well as in the
name, place and stead of such Issuer Secured Party such acts, things and deeds
for or on behalf of and in the name of such Issuer Secured Party under this
Indenture (including specifically under Section 5.4) and under the Basic
Documents which such Issuer Secured Party could or might do or which may be
necessary, desirable or convenient in such Controlling Party's sole discretion
to effect the purposes contemplated hereunder and under the Basic Documents and,
without limitation, following the occurrence of an Event of Default, exercise
full right, power and authority to take, or defer from taking, any and all acts
with respect to the administration, maintenance or disposition of the Trust
Estate. 

               (c) If an Event of Default occurs and is continuing, the Trustee
may in its discretion but with the consent of the Controlling Party and shall,
at the direction of the Controlling Party (except as provided in Section 5.3(d)
below), proceed to protect and enforce its rights and the rights of the
Noteholders by such appropriate Proceedings as the Trustee or the Controlling
Party shall deem most effective to protect and enforce any such rights, whether
for the specific enforcement of any covenant or agreement in this Indenture or
in aid of the exercise of any power granted herein, or to enforce any other
proper remedy or legal or equitable right vested in the Trustee by this
Indenture or by law. 

               (d) Notwithstanding anything to the contrary contained in this 
Indenture (including, without limitation, Sections 5.4(a), 5.12, 5.13 and 5.17)
and regardless of whether an Insurer Default shall have occurred and be
continuing, if the Issuer fails to perform its obligations under Section 10.1(b)
hereof when and as due, the Trustee may in its discretion (and without the
consent of the Controlling Party) proceed to protect and enforce its rights and
the rights of the Noteholders by such appropriate proceedings as the Trustee
shall deem most effective to protect and enforce any such rights, whether for
specific performance of any 

                                       33
<PAGE>
 
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy or legal or equitable
right vested in the Trustee by this Indenture or by law; provided that the
Trustee shall only be entitled to take any such actions without the consent of
the Controlling Party to the extent such actions (x) are taken only to enforce
the Issuer's obligations to redeem the principal amount of Notes and (y) are
taken only against the portion of the Collateral, if any, consisting of the Pre-
Funding Account, the Capitalized Interest Account, any investments therein and
any proceeds thereof.

               (e) In case there shall be pending, relative to the Issuer or 
any other obligor upon the Notes or any Person having or claiming an ownership
interest in the Trust Estate, proceedings under Title 11 of the United States
Code or any other applicable federal or State bankruptcy, insolvency or other
similar law, or in case a receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Issuer or its property or such other
obligor or Person, or in case of any other comparable judicial proceedings
relative to the Issuer or other obligor upon the Notes, or to the creditors or
property of the Issuer or such other obligor, the Trustee, irrespective of
whether the principal of any Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section, shall be
entitled and empowered, by intervention in such proceedings or otherwise: 

                    (i) to file and prove a claim or claims for the whole amount
               of principal and interest owing and unpaid in respect of the
               Notes and to file such other papers or documents as may be
               necessary or advisable in order to have the claims of the Trustee
               (including any claim for reasonable compensation to the Trustee
               and each predecessor Trustee, and their respective agents,
               attorneys and counsel, and for reimbursement of all expenses and
               liabilities incurred, and all advances made, by the Trustee and
               each predecessor Trustee, except as a result of negligence, bad
               faith or willful misconduct) and of the Noteholders allowed in
               such proceedings;

                    (ii) unless prohibited by applicable law and regulations, to
               vote on behalf of the Noteholders in any election of a trustee, a
               standby trustee or person performing similar functions in any
               such proceedings; 

                    (iii) to collect and receive any moneys or other property
               payable or deliverable on any such claims and to distribute all
               amounts received with respect to the claims of the Noteholders
               and of the Trustee on their behalf; and 

                    (iv) to file such proofs of claim and other papers or
               documents as may be necessary or advisable in order to have the
               claims of the Trustee or the Noteholders allowed in any judicial
               proceedings relative to the Issuer, its creditors and its
               property; 

and any trustee, receiver, liquidator, custodian or other similar official in
any such proceeding is hereby authorized by each of such Noteholders to make
payments to the Trustee, and, in the event that the Trustee shall consent to the
making of payments directly to such Noteholders, to 

                                       34
<PAGE>
 
pay to the Trustee such amounts as shall be sufficient to cover reasonable
compensation to the Trustee, each predecessor Trustee and their respective
agents, attorneys and counsel, and all other expenses and liabilities incurred,
and all advances made, by the Trustee and each predecessor Trustee except as a
result of negligence or bad faith.

               (f) Nothing herein contained shall be deemed to authorize the 
Trustee to authorize or consent to or vote for or accept or adopt on behalf of
any Noteholder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder thereof or to
authorize the Trustee to vote in respect of the claim of any Noteholder in any
such proceeding except, as aforesaid, to vote for the election of a trustee in
bankruptcy or similar person.

               (g) All rights of action and of asserting claims under this 
Indenture, the Spread Account Agreement or under any of the Notes, may be
enforced by the Trustee without the possession of any of the Notes or the
production thereof in any trial or other proceedings relative thereto, and any
such action or proceedings instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment, subject to
the payment of the expenses, disbursements and compensation of the Trustee, each
predecessor Trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Holders of the Notes. 

               (h) In any proceedings brought by the Trustee (and also any 
proceedings involving the interpretation of any provision of this Indenture or
the Spread Account Agreement), the Trustee shall be held to represent all the
Holders of the Notes, and it shall not be necessary to make any Noteholder a
party to any such proceedings.

               SECTION 5.4 Remedies.

               (a) If an Event of Default shall have occurred and be 
continuing, the Controlling Party may do one or more of the following (subject
to Section 5.5):

                    (i) institute Proceedings in its own name and as trustee of
               an express trust for the collection of all amounts then payable
               on the Notes or under this Indenture with respect thereto,
               whether by declaration or otherwise, enforce any judgment
               obtained, and collect from the Issuer and any other obligor upon
               such Notes moneys adjudged due;

                    (ii) institute Proceedings from time to time for the
               complete or partial foreclosure of this Indenture with respect to
               the Trust Estate; 

                    (iii) exercise any remedies of a secured party under the UCC
               and take any other appropriate action to protect and enforce the
               rights and remedies of the Trustee and the Holders of the Notes;
               and 

                    (iv) direct the Trust Collateral Agent to sell the Trust
               Estate or any portion thereof or rights or interest therein, at
               one or more public or private sales called and conducted in any
               manner permitted by law; provided, however, that 

                                       35
<PAGE>
 
               (A) if the Security Insurer is the Controlling Party, the
          Security Insurer may not sell or otherwise liquidate the Trust Estate
          following an Insurance Agreement Indenture Cross Default unless

                         (I) such Insurance Agreement Indenture Cross Default
                    arises from a claim being made on the Note Policy or from
                    the insolvency of the Trust or the Seller, or

                         (II) the proceeds of such sale or liquidation
                    distributable to the Noteholders are sufficient to discharge
                    in full all amounts then due and unpaid upon such Notes for
                    principal and interest; or 

               (B) if the Trustee is the Controlling Party, the Trustee may not
          sell or otherwise liquidate the Trust Estate following an Event of
          Default unless

                         (I) such Event of Default is of the type described in
                    Section 5.01(i) or (ii), or

                         (II) either

                              (x) the Holders of 100% of the Outstanding Amount
                         of the Notes consent thereto,

                              (y) the proceeds of such sale or liquidation
                         distributable to the Noteholders are sufficient to
                         discharge in full all amounts then due and unpaid
                         upon such Notes for principal and interest, or

                              (z) the Trustee determines that the Trust Estate 
                         will not continue to provide sufficient funds for the
                         payment of principal of and interest on the Notes as 
                         they would have become due if the Notes had not been 
                         declared due and payable, and the Trustee provides 
                         prior written notice to the Rating Agencies and 
                         obtains the consent of Holders of 66-2/3% of the 
                         Outstanding Amount of the Notes.

               In determining such sufficiency or insufficiency with respect to
clause (y) and (z), the Trustee may, but need not, obtain and conclusively rely
upon an opinion of an Independent investment banking or accounting firm of
national reputation as to the feasibility of such proposed action and as to the
sufficiency of the Trust Estate for such purpose.

               SECTION 5.5 Optional Preservation of the Receivables. If the
Trustee is the Controlling Party and if the Notes have been declared to be due
and payable under Section 5.2 following an Event of Default and such declaration
and its consequences have not been rescinded and annulled, the Trustee may, but
need not, elect to direct the Trust Collateral Agent to maintain possession of
the Trust Estate. It is the desire of the parties hereto and the Noteholders
that there be at all times sufficient funds for the payment of principal of and
interest on the Notes, and the Trustee shall take such desire into account when
determining whether or not to direct the Trust Collateral Agent to maintain
possession of the Trust Estate. In determining whether to direct the 

                                       36
<PAGE>
 
Trust Collateral Agent to maintain possession of the Trust Estate, the Trustee
may, but need not, obtain and conclusively rely upon an opinion of an
Independent investment banking or accounting firm of national reputation as to
the feasibility of such proposed action and as to the sufficiency of the Trust
Estate for such purpose.

               SECTION 5.6 Priorities .

               (a) Following (1) the acceleration of the Notes pursuant to 
Section 5.2 or (2) if an Insurer Default shall have occurred and be continuing,
the occurrence of an Event of Default pursuant to Section 5.1(i), 5.1(ii),
5.1(iv), 5.1(v) or 5.1(vi) of the Indenture or (3) the receipt of Insolvency
Proceeds pursuant to Section 10.1(b) of the Sale and Servicing Agreement, the
Distribution Amount, including any money or property collected pursuant to
Section 5.4 of the Indenture and any such Insolvency Proceeds, shall be applied
by the Trust Collateral Agent on the related Distribution Date in the following
order of priority:

               FIRST: amounts due and owing and required to be distributed to
       the Servicer (provided there is no Servicer Event of Default), the Owner
       Trustee, the Trustee, the Collateral Agent, Back Up Servicer and the
       Trust Collateral Agent, respectively, pursuant to priorities (i) and (ii)
       of Section 5.7(b) of the Sale and Servicing Agreement and not previously
       distributed, in the order of such priorities and without preference or
       priority of any kind within such priorities;

               SECOND: to Noteholders for amounts due and unpaid on the Notes
          for interest, ratably, without preference or priority of any kind,
          according to the amounts due and payable on the Notes for interest;

               THIRD: to Noteholders for amounts due and unpaid on the Notes for
          principal, ratably, without preference or priority of any kind,
          according to the amounts due and payable on the Notes for principal;

               FOURTH: amounts due and owing and required to be distributed to
          the Security Insurer pursuant to priority (v) of Section 5.7(b) of the
          Sale and Servicing Agreement and not previously distributed); and

               FIFTH: to the Collateral Agent to be applied as provided in the
          Spread Account Agreement;

provided that any amounts collected from the Pre-Funding Account or the
Capitalized Interest Account shall be paid, first, for amounts due and unpaid on
the Notes for principal for distribution to Noteholders in accordance with
Section 10.1(b) and, second, in accordance with priorities FIRST through FIFTH
above.

               (b) The Trustee may fix a record date and payment date for any 
payment to Noteholders pursuant to this Section 5.6. At least 15 days before
such record date the Issuer shall mail to each Noteholder and the Trustee a
notice that states the record date, the payment date and the amount to be paid.

                                       37

               SECTION 5.7 Limitation of Suits. No Holder of any Note shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

                    (i) such Holder has previously given written notice to the
               Trustee of a continuing Event of Default;

                    (ii) the Holders of not less than 25% of the Outstanding
               Amount of the Notes have made written request to the Trustee to
               institute such proceeding in respect of such Event of Default in
               its own name as Trustee hereunder; 

                    (iii) such Holder or Holders have offered to the Trustee
               indemnity reasonably satisfactory to it against the costs,
               expenses and liabilities to be incurred in complying with such
               request; 

                    (iv) the Trustee for 60 days after its receipt of such
               notice, request and offer of indemnity has failed to institute
               such proceedings; 

                    (v) no direction inconsistent with such written request has
               been given to the Trustee during such 60-day period by the
               Holders of a majority of the Outstanding Amount of the Notes; and

                    (vi) an Insurer Default shall have occurred and be
               continuing; 

it being understood and intended that no one or more Noteholders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other
Noteholders or to obtain or to seek to obtain priority or preference over any
other Holders or to enforce any right under this Indenture, except in the manner
herein provided.

               In the event the Trustee shall receive conflicting or
inconsistent requests and indemnity from two or more groups of Noteholders, each
representing less than a majority of the Outstanding Amount of the Notes, the
Trustee in its sole discretion may determine what action, if any, shall be
taken, notwithstanding any other provisions of this Indenture.

               SECTION 5.8 Unconditional Rights of Noteholders To Receive
Principal and Interest. Notwithstanding any other provisions in this Indenture,
the Holder of any Note shall have the right, which is absolute and
unconditional, to receive payment of the principal of and interest, if any, on
such Note on or after the respective due dates thereof expressed in such Note or
in this Indenture (or, in the case of redemption, on or after the Redemption
Date) and to institute suit for the enforcement of any such payment, and such
right shall not be impaired without the consent of such Holder.

               SECTION 5.9 Restoration of Rights and Remedies. If the
Controlling Party or any Noteholder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason or has been determined adversely to the Trustee or
to such Noteholder, then and in every such case the Issuer, the Trustee and the
Noteholders shall, subject to any determination in such Proceeding, be

                                       38
<PAGE>
 
restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Noteholders shall
continue as though no such proceeding had been instituted.

               SECTION 5.10 Rights and Remedies Cumulative. No right or remedy
herein conferred upon or reserved to the Controlling Party or to the Noteholders
is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

               SECTION 5.11 Delay or Omission Not a Waiver. No delay or
omission of the Trustee, the Controlling Party or any Holder of any Note to
exercise any right or remedy accruing upon any Default or Event of Default shall
impair any such right or remedy or constitute a waiver of any such Default or
Event of Default or an acquiescence therein. Every right and remedy given by
this Article V or by law to the Trustee or to the Noteholders may be exercised
from time to time, and as often as may be deemed expedient, by the Trustee or by
the Noteholders, as the case may be.

               SECTION 5.12 Control by Noteholders. If the Trustee is the
Controlling Party, the Holders of a majority of the Outstanding Amount of the
Notes shall have the right to direct the time, method and place of conducting
any Proceeding for any remedy available to the Trustee with respect to the Notes
or exercising any trust or power conferred on the Trustee; provided that

                    (i) such direction shall not be in conflict with any rule of
               law or with this Indenture;

                    (ii) subject to the express terms of Section 5.4, any
               direction to the Trustee to sell or liquidate the Trust Estate
               shall be by the Noteholders representing not less than 100% of
               the Outstanding Amount of the Notes; 

                    (iii) if the conditions set forth in Section 5.5 have been
               satisfied and the Trustee elects to retain the Trust Estate
               pursuant to such Section, then any direction to the Trustee by
               Noteholders representing less than 100% of the Outstanding Amount
               of the Notes to sell or liquidate the Trust Estate shall be of no
               force and effect; and 

                    (iv) the Trustee may take any other action deemed proper by
               the Trustee that is not inconsistent with such direction;
             
provided, however, that, subject to Article VI, the Trustee need not take any
action that it determines might involve it in liability or might materially
adversely affect the rights of any Noteholders not consenting to such action.

               SECTION 5.13 Waiver of Past Defaults. If an Insurer Default
shall have occurred and be continuing, prior to the declaration of the
acceleration of the maturity of the Notes as provided in Section 5.4, the
Noteholders of not less than a majority of the Outstanding 

                                       39
<PAGE>
 
Amount of the Notes may waive any past Default or Event of Default and its
consequences except a Default (a) in payment of principal of or interest on any
of the Notes or (b) in respect of a covenant or provision hereof which cannot be
modified or amended without the consent of the Holder of each Note. In the case
of any such waiver, the Issuer, the Trustee and the Holders of the Notes shall
be restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other Default or impair any right
consequent thereto.

               Upon any such waiver, such Default shall cease to exist and be
deemed to have been cured and not to have occurred, and any Event of Default
arising therefrom shall be deemed to have been cured and not to have occurred,
for every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right consequent
thereto.

               SECTION 5.14 Undertaking for Costs. All parties to this
Indenture agree, and each Holder of any Note by such Holder's acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in
any suit for the enforcement of any right or remedy under this Indenture, or in
any suit against the Trustee for any action taken, suffered or omitted by it as
Trustee, the filing by any party litigant in such suit of an undertaking to pay
the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys' fees, against any party
litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this
Section shall not apply to (a) any suit instituted by the Trustee, (b) any suit
instituted by any Noteholder, or group of Noteholders, in each case holding in
the aggregate more than 10% of the Outstanding Amount of the Notes or (c) any
suit instituted by any Noteholder for the enforcement of the payment of
principal of or interest on any Note on or after the respective due dates
expressed in such Note and in this Indenture (or, in the case of redemption, on
or after the Redemption Date).

               SECTION 5.15 Waiver of Stay or Extension Laws. The Issuer
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead or in any manner whatsoever, claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, that may affect the covenants or the performance of
this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

               SECTION 5.16 Action on Notes. The Trustee's right to seek and
recover judgment on the Notes or under this Indenture shall not be affected by
the seeking, obtaining or application of any other relief under or with respect
to this Indenture. Neither the lien of this Indenture nor any rights or remedies
of the Trustee or the Noteholders shall be impaired by the recovery of any
judgment by the Trustee against the Issuer or by the levy of any execution under
such judgment upon any portion of the Trust Estate or upon any of the assets of
the Issuer.

               SECTION 5.17 Performance and Enforcement of Certain Obligations.

                                       40
<PAGE>
 
(a) Promptly following a request from the Trustee to do so and at the Servicer's
expense, the Issuer agrees to take all such lawful action as the Trustee may
request to compel or secure the performance and observance by the Seller and the
Servicer, as applicable, of each of their obligations to the Issuer under or in
connection with the Sale and Servicing Agreement in accordance with the terms
thereof, and to exercise any and all rights, remedies, powers and privileges
lawfully available to the Issuer under or in connection with the Sale and
Servicing Agreement to the extent and in the manner directed by the Trustee,
including the transmission of notices of default on the part of the Seller or
the Servicer thereunder and the institution of legal or administrative actions
or proceedings to compel or secure performance by the Seller or the Servicer of
each of their obligations under the Sale and Servicing Agreement.

(b) If the Trustee is a Controlling Party and if an Event of Default has
occurred and is continuing, the Trustee may, and, at the written direction of
the Holders of 66-2/3% of the Outstanding Amount of the Notes shall, subject to
Article VI, exercise all rights, remedies, powers, privileges and claims of the
Issuer against the Seller or the Servicer under or in connection with the Sale
and Servicing Agreement, including the right or power to take any action to
compel or secure performance or observance by the Seller or the Servicer of each
of their obligations to the Issuer thereunder and to give any consent, request,
notice, direction, approval, extension or waiver under the Sale and Servicing
Agreement, and any right of the Issuer to take such action shall be suspended.

                                   ARTICLE VI

                   The Trustee and the Trust Collateral Agent

               SECTION 6.1 Duties of Trustee.

               (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise the rights and powers vested in it by this Indenture and
the Basic Documents to which is a Party and use the same degree of care and
skill in its exercise as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs.

               (b) Except during the continuance of an Event of Default:

                    (i) the Trustee undertakes to perform such duties and only
               such duties as are specifically set forth in this Indenture and
               no implied covenants or obligations shall be read into this
               Indenture against the Trustee; and

                    (ii) in the absence of bad faith on its part, the Trustee
               may conclusively rely, as to the truth of the statements and the
               correctness of the opinions expressed therein, upon certificates
               or opinions furnished to the Trustee and conforming to the
               requirements of this Indenture; however, the Trustee shall
               examine the certificates and opinions to determine whether or not
               they conform on their face to the requirements of this Indenture.

               (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

                                       41
<PAGE>
 
                    (i) this paragraph does not limit the effect of paragraph
               (b) of this Section;

                    (ii) the Trustee shall not be liable for any error of
               judgment made in good faith by a Responsible Officer unless it is
               proved that the Trustee was negligent in ascertaining the
               pertinent facts; and 

                    (iii) the Trustee shall not be liable with respect to any
               action it takes or omits to take in good faith in accordance with
               a direction received by it pursuant to Section 5.12. 

               (d) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Issuer.

               (e) Money held in trust by the Trustee need not be segregated
from other funds except to the extent required by law or the terms of this
Indenture or the Sale and Servicing Agreement. 

               (f) No provision of this Indenture shall require the Trustee 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 it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it. 

               (g) Every provision of this Indenture relating to the conduct or

               (h) The Trustee shall, upon two Business Days' prior notice to
the Trustee, permit any representative of the Security Insurer at the expense of
the Trust, during the Trustee's normal business hours, to examine all books of
account, records, reports and other papers of the Trustee relating to the Notes,
to make copies and extracts therefrom and to discuss the Trustee's affairs and
actions, as such affairs and actions relate to the Trustee's duties with respect
to the Notes, with the Trustee's officers and employees responsible for carrying
out the Trustee's duties with respect to the Notes. 

               (i) The Trustee shall, and hereby agrees that it will, perform
all of the obligations and duties required of it under the Sale and Servicing
Agreement. 

               (j) The Trustee shall, and hereby agrees that it will, hold the

in trust solely for the use and benefit of the Noteholders. 

               (k) Without limiting the generality of this Section 6.1, the
Trustee shall have no duty (i) to see to any recording, filing or depositing of
this Indenture or any agreement referred to herein or any financing statement
evidencing a security interest in the Financed 

                                       42
<PAGE>

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

of the Receivable Files under the Sale and Servicing Agreement.

               (l) In no event shall Bank One, NA, in any of its capacities
hereunder, be deemed to have assumed any duties of the Owner Trustee under the
Delaware Business Trust Statute, common law, or the Trust Agreement.

               SECTION 6.2 Rights of Trustee.

               (a) The Trustee may conclusively rely on any document believed by
it to be genuine and to have been signed or presented by the proper person. The
Trustee need not investigate any fact or matter stated in the document.

               (b) Before the Trustee acts or refrains from acting, it may
require an Officer's Certificate or an Opinion of Counsel. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
the Officer's Certificate or Opinion of Counsel. 

               (c) The Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through agents or
attorneys or a custodian or nominee, and the Trustee shall not be responsible
for any misconduct or negligence on the part of, or for the supervision of,
AmeriCredit Financial Services, Inc., or any other such agent, attorney,
custodian or nominee appointed with due care by it hereunder. 

               (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers; provided, however, that the Trustee's conduct does not
constitute willful misconduct, negligence or bad faith. 

               (e) The Trustee may consult with counsel, and the advice or
opinion of counsel with respect to legal matters relating to this Indenture and
the Notes shall be full and complete authorization and protection from liability
in respect to any action taken, omitted or suffered by it hereunder in good
faith and in accordance with the advice or opinion of such counsel. 

               (f) The Trustee shall be under no obligation to institute,
conduct or defend any litigation under this Indenture or in relation to this
Indenture, at the request, order or direction of any of the Noteholders or the
Controlling Party, pursuant to the provisions of this Indenture, unless such
Noteholders or the Controlling Party shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that may be incurred therein or thereby; provided, however, that the Trustee
shall, upon the occurrence of an Event of 

                                       43
<PAGE>
 
Default (that has not been cured), exercise the rights and powers vested in it
by this Indenture with reasonable care and skill.

               (g) The Trustee shall not be bound to make any investigation into
the facts or 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 to do so by the Security
Insurer (so long as no Insurer Default shall have occurred and be continuing) or
(if an Insurer Default shall have occurred and be continuing) by the Noteholders
evidencing not less than 25% of the Outstanding Amount thereof; provided,
however, that if the payment within a reasonable time to the Trustee of the
costs, expenses or liabilities likely to be incurred by it in the making of such
investigation is, in the opinion of the Trustee, not reasonably assured to the
Trustee by the security afforded to it by the terms of this Indenture or the
Sale and Servicing Agreement, the Trustee 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 Person making
such request, or, if paid by the Trustee, shall be reimbursed by the Person
making such request upon demand. 

               (h) The Trustee shall not be liable for any losses on investments
except for losses resulting from the failure of the Trustee to make an
investment in accordance with instructions given in accordance hereunder. If the
Trustee acts as the Note Paying Agent or Note Registrar, the rights and
protections afforded to the Trustee shall be afforded to the Note Paying Agent
and Note Registrar.

               SECTION 6.3 Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and
may otherwise deal with the Issuer or its Affiliates with the same rights it
would have if it were not Trustee. Any Note Paying Agent, Note Registrar,
co-registrar or co-Note Paying Agent may do the same with like rights. However,
the Trustee must comply with Sections 6.11 and 6.12.

               SECTION 6.4 Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture, the Trust Estate or the Notes, it shall not be accountable for
the Issuer's use of the proceeds from the Notes, and it shall not be responsible
for any statement of the Issuer in the Indenture or in any document issued in
connection with the sale of the Notes or in the Notes other than the Trustee's
certificate of authentication.

               SECTION 6.5 Notice of Defaults. If an Event of Default occurs
and is continuing and if it is either known by, or written notice of the
existence thereof has been delivered to, a Responsible Officer of the Trustee,
the Trustee shall mail to each Noteholder notice of the Default within 90 days
after such knowledge or notice occurs. Except in the case of a Default in
payment of principal of or interest on any Note (including payments pursuant to
the mandatory redemption provisions of such Note), the Trustee may withhold the
notice if and so long as a committee of two or more of its Responsible Officers
in good faith determines that withholding the notice is in the interests of
Noteholders.

                                       44

               SECTION 6.6 Reports by Trustee to Holders. The Trustee shall
deliver to each Noteholder such information as may be reasonably required to
enable such Holder to prepare its federal and State income tax returns.

               SECTION 6.7 Compensation and Indemnity.

               (a) Pursuant to Section 5.7(b) of the Sale and Servicing
Agreement, the Issuer shall, or shall cause the Servicer to, pay to the Trustee
from time to time compensation for its services. The Trustee's compensation
shall not be limited by any law on compensation of a trustee of an express
trust. The Issuer shall cause the Servicer to reimburse the Trustee and the
Trust Collateral Agent for all reasonable out-of-pocket expenses incurred or
made by it, including costs of collection, in addition to the compensation for
its services. Such expenses shall include the reasonable compensation and
expenses, disbursements and advances of the Trustee's, the Backup Servicer's,
the Collateral Agent's and the Trust Collateral Agent's agents, counsel,
accountants and experts. The Issuer shall cause the Servicer to indemnify the
Trustee, the Trust Collateral Agent and their respective officers, directors,
employees and agents against any and all loss, liability or expense (including
attorneys' fees and expenses) incurred by each of them in connection with the
acceptance or the administration of this trust and the performance of its duties
hereunder. The Trustee, Trust Collateral Agent, the Collateral Agent or the
Backup Servicer shall notify the Issuer and the Servicer promptly of any claim
for which it may seek indemnity. Failure by the Trustee or Trust Collateral
Agent to so notify the Issuer and the Servicer shall not relieve the Issuer of
its obligations hereunder or the Servicer of its obligations under Article XI of
the Sale and Servicing Agreement. The Issuer shall cause the Servicer to defend
the claim, the Trustee, Trust Collateral Agent, the Collateral Agent or the
Backup Servicer may have separate counsel and the Issuer shall cause the
Servicer to pay the fees and expenses of such counsel. Neither the Issuer nor
the Servicer need reimburse any expense or indemnify against any loss, liability
or expense incurred by the Trustee or Trust Collateral Agent through the
Trustee's or Trust Collateral Agent's own willful misconduct, negligence or bad
faith.

               (b) The Issuer's payment obligations to the Trustee pursuant to
this Section shall survive the discharge of this Indenture or the earlier
resignation or removal of the Trustee or the Trust Collateral Agent or the
Collateral Agent or the Backup Servicer. When the Trustee, the Trust Collateral
Agent, the Collateral Agent or the Backup Servicer incurs expenses after the
occurrence of a Default specified in Section 5.1(v) or (vi) with respect to the
Issuer, the expenses are intended to constitute expenses of administration under
Title 11 of the United States Code or any other applicable federal or State
bankruptcy, insolvency or similar law. Notwithstanding anything else set forth
in this Indenture or the Basic Documents, the Trustee agrees that the
obligations of the Issuer (but not the Servicer) to the Trustee hereunder and
under the Basic Documents shall be recourse to the Trust Estate only and
specifically shall not be recourse to the assets of the Certificateholder or any
Noteholder. In addition, the Trustee agrees that its recourse to the Issuer, the
Trust Estate, the Seller and amounts held pursuant of the Spread Account
Agreement shall be limited to the right to receive the distributions referred to
in Section 5.7(b) of the Sale and Servicing Agreement.

               SECTION 6.8 Replacement of Trustee. The Trustee may resign at
any time by so notifying the Issuer and the Security Insurer. The Issuer may
and, at the request of the 

                                       45
<PAGE>
 
Security Insurer (unless an Insurer Default shall have occurred and be
continuing) shall, remove the Trustee, if:

                    (i) the Trustee fails to comply with Section 6.11;

                    (ii) a court having jurisdiction in the premises in respect
               of the Trustee in an involuntary case or proceeding under federal
               or state banking or bankruptcy laws, as now or hereafter
               constituted, or any other applicable federal or state bankruptcy,
               insolvency or other similar law, shall have entered a decree or
               order granting relief or appointing a receiver, liquidator,
               assignee, custodian, trustee, conservator, sequestrator (or
               similar official) for the Trustee or for any substantial part of
               the Trustee's property, or ordering the winding-up or liquidation
               of the Trustee's affairs; 

                    (iii) an involuntary case under the federal bankruptcy laws,
               as now or hereafter in effect, or another present or future
               federal or state bankruptcy, insolvency or similar law is
               commenced with respect to the Trustee and such case is not
               dismissed within 60 days; 

                    (iv) the Trustee commences a voluntary case under any
               federal or state banking or bankruptcy laws, as now or hereafter
               constituted, or any other applicable federal or state bankruptcy,
               insolvency or other similar law, or consents to the appointment
               of or taking possession by a receiver, liquidator, assignee,
               custodian, trustee, conservator, sequestrator (or other similar
               official) for the Trustee or for any substantial part of the
               Trustee's property, or makes any assignment for the benefit of
               creditors or fails generally to pay its debts as such debts
               become due or takes any corporate action in furtherance of any of
               the foregoing; or 

                    (v) the Trustee otherwise becomes incapable of acting.

               If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason (the Trustee in such event being referred
to herein as the retiring Trustee), the Issuer shall promptly appoint a
successor Trustee acceptable to the Security Insurer (so long as an Insurer
Default shall not have occurred and be continuing). If the Issuer fails to
appoint such a successor Trustee, the Security Insurer may appoint a successor
Trustee.

               A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee, the Security Insurer (provided that no
Insurer Default shall have occurred and be continuing) and to the Issuer.
Thereupon the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have all the rights, powers and
duties of the retiring Trustee under this Indenture subject to satisfaction of
the Rating Agency Condition. The successor Trustee shall mail a notice of its
succession to Noteholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee.

               If a successor Trustee does not take office within 60 days after
the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or
the Holders of a majority in Outstanding 

                                       46
<PAGE>
 
Amount of the Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

               If the Trustee fails to comply with Section 6.11, any Noteholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

               Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section shall not
become effective until acceptance of appointment by the successor Trustee
pursuant to Section 6.8 and payment of all fees and expenses owed to the
outgoing Trustee.

               Notwithstanding the replacement of the Trustee pursuant to this
Section, the Issuer's and the Servicer's obligations under Section 6.7 shall
continue for the benefit of the retiring Trustee.

               SECTION 6.9 Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee. The Trustee shall provide the Rating
Agencies prior written notice of any such transaction.

               In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Notes shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to the Trustee may authenticate such Notes either
in the name of any predecessor hereunder or in the name of the successor to the
Trustee; and in all such cases such certificates shall have the full force which
it is anywhere in the Notes or in this Indenture provided that the certificate
of the Trustee shall have.

               SECTION 6.10 Appointment of Co-Trustee or Separate Trustee.

               (a) Notwithstanding any other provisions of this Indenture, at
any time, for the purpose of meeting any legal requirement of any jurisdiction
in which any part of the Trust may at the time be located, the Trustee with the
consent of the Security Insurer (so long as an Insurer Default shall not have
occurred and be continuing) shall have the power and may execute and deliver all
instruments to appoint one or more Persons to act as a co-trustee or
co-trustees, or separate trustee or separate trustees, of all or any part of the
Trust, and to vest in such Person or Persons, in such capacity and for the
benefit of the Noteholders, such title to the Trust, or any part hereof, and,
subject to the other provisions of this Section, such powers, duties,
obligations, rights and trusts as the Trustee may consider necessary or
desirable. No co-trustee or separate trustee hereunder shall be required to meet
the terms of eligibility as a successor trustee under Section 6.11 and no notice
to Noteholders of the appointment of any co-trustee or separate trustee shall be
required under Section 6.8 hereof.

                                       47
<PAGE>
 
               (b) Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions: 

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

                    (ii) no trustee hereunder shall be personally liable by
               reason of any act or omission of any other trustee hereunder,
               including acts or omissions of predecessor or successor trustees;
               and 

                    (iii) the Trustee may at any time accept the resignation of
               or remove any separate trustee or co-trustee. 

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

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

               (e) Any and all amounts relating to the fees and expenses of the
co-trustee or separate trustee will be borne by the Trust Estate. 

               SECTION 6.11 Eligibility: Disqualification. The Trustee shall at
all times satisfy the requirements of TIA ss. 310(a). The Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition and it shall have a long term debt
rating of BBB- or better by the Rating Agencies. The Trustee shall 

                                       48
<PAGE>
 
provide copies of such reports to the Security Insurer upon request. The Trustee
shall comply with TIA ss. 310(b), including the optional provision permitted by
the second sentence of TIA ss. 310(b)(9); provided, however, that there shall be
excluded from the operation of TIA ss. 310(b)(1) any indenture or indentures
under which other securities of the Issuer are outstanding if the requirements
for such exclusion set forth in TIA ss. 310(b)(1) are met.

               SECTION 6.12 Preferential Collection of Claims Against Issuer.
The Trustee shall comply with TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated.

               SECTION 6.13 Appointment and Powers. Subject to the terms and
conditions hereof, each of the Issuer Secured Parties hereby appoints Bank One,
NA as the Trust Collateral Agent with respect to the Collateral, and Bank One,
NA hereby accepts such appointment and agrees to act as Trust Collateral Agent
with respect to the Indenture Collateral for the Issuer Secured Parties, to
maintain custody and possession of such Indenture Collateral (except as
otherwise provided hereunder) and to perform the other duties of the Trust
Collateral Agent in accordance with the provisions of this Indenture and the
other Basic Documents. Each Issuer Secured Party hereby authorizes the Trust
Collateral Agent to take such action on its behalf, and to exercise such rights,
remedies, powers and privileges hereunder, as the Controlling Party may direct
and as are specifically authorized to be exercised by the Trust Collateral Agent
by the terms hereof, together with such actions, rights, remedies, powers and
privileges as are reasonably incidental thereto. The Trust Collateral Agent
shall act upon and in compliance with the written instructions of the
Controlling Party delivered pursuant to this Indenture promptly following
receipt of such written instructions; provided that the Trust Collateral Agent
shall not act in accordance with any instructions (i) which are not authorized
by, or in violation of the provisions of, this Indenture, (ii) which are in
violation of any applicable law, rule or regulation or (iii) for which the Trust
Collateral Agent has not received reasonable indemnity. Receipt of such
instructions shall not be a condition to the exercise by the Trust Collateral
Agent of its express duties hereunder, except where this Indenture provides that
the Trust Collateral Agent is permitted to act only following and in accordance
with such instructions.

               SECTION 6.14 Performance of Duties. The Trust Collateral Agent
shall have no duties or responsibilities except those expressly set forth in
this Indenture and the other Basic Documents to which the Trust Collateral Agent
is a party or as directed by the Controlling Party in accordance with this
Indenture. The Trust Collateral Agent shall not be required to take any
discretionary actions hereunder except at the written direction and with the
indemnification of the Controlling Party. The Trust Collateral Agent shall, and
hereby agrees that it will, subject to this Article, perform all of the duties
and obligations required of it under the Sale and Servicing Agreement.

               SECTION 6.15 Limitation on Liability. Neither the Trust
Collateral Agent nor any of its directors, officers or employees shall be liable
for any action taken or omitted to be taken by it or them hereunder, or in
connection herewith, except that the Trust Collateral Agent shall be liable for
its negligence, bad faith or willful misconduct; nor shall the Trust Collateral
Agent be responsible for the validity, effectiveness, value, sufficiency or
enforceability against the Issuer of this Indenture or any of the Indenture
Collateral (or any part thereof). 

                                       49
<PAGE>
 
Notwithstanding any term or provision of this Indenture, the Trust Collateral
Agent shall incur no liability to the Issuer or the Issuer Secured Parties for
any action taken or omitted by the Trust Collateral Agent in connection with the
Indenture Collateral, except for the negligence, bad faith or willful misconduct
on the part of the Trust Collateral Agent, and, further, shall incur no
liability to the Issuer Secured Parties except for negligence, bad faith or
willful misconduct in carrying out its duties to the Issuer Secured Parties. The
Trust Collateral Agent shall be protected and shall incur no liability to any
such party in relying upon the accuracy, acting in reliance upon the contents,
and assuming the genuineness of any notice, demand, certificate, signature,
instrument or other document reasonably believed by the Trust Collateral Agent
to be genuine and to have been duly executed by the appropriate signatory, and
(absent actual knowledge to the contrary by a Responsible Officer of the Trust
Collateral Agent) the Trust Collateral Agent shall not be required to make any
independent investigation with respect thereto. The Trust Collateral Agent shall
at all times be free independently to establish to its reasonable satisfaction,
but shall have no duty to independently verify, the existence or nonexistence of
facts that are a condition to the exercise or enforcement of any right or remedy
hereunder or under any of the Basic Documents. The Trust Collateral Agent may
consult with counsel, and shall not be liable for any action taken or omitted to
be taken by it hereunder in good faith and in accordance with the advice of such
counsel. The Trust Collateral Agent shall not be under any obligation to
exercise any of the remedial rights or powers vested in it by this Indenture or
to follow any direction from the Controlling Party or risk its own funds or
otherwise incur financial liability in the performance of any of its duties
hereunder unless it shall have received reasonable security or indemnity
satisfactory to the Trust Collateral Agent against the costs, expenses and
liabilities which might be incurred by it.

               SECTION 6.16 Reliance Upon Documents. In the absence of
negligence, bad faith or willful misconduct on its part, the Trust Collateral
Agent shall be entitled to conclusively rely on any communication, instrument,
paper or other document reasonably believed by it to be genuine and correct and
to have been signed or sent by the proper Person or Persons and shall have no
liability in acting, or omitting to act, where such action or omission to act is
in reasonable reliance upon any statement or opinion contained in any such
document or instrument.

               SECTION 6.17 Successor Trust Collateral Agent.

               (a) Merger. Any Person into which the Trust Collateral Agent may
be converted or merged, or with which it may be consolidated, or to which it may
sell or transfer its trust business and assets as a whole or substantially as a
whole, or any Person resulting from any such conversion, merger, consolidation,
sale or transfer to which the Trust Collateral Agent is a party, shall (provided
it is otherwise qualified to serve as the Trust Collateral Agent hereunder) be
and become a successor Trust Collateral Agent hereunder and be vested with all
of the title to and interest in the Indenture Collateral and all of the trusts,
powers, discretions, immunities, privileges and other matters as was its
predecessor without the execution or filing of any instrument or any further
act, deed or conveyance on the part of any of the parties hereto, anything
herein to the contrary notwithstanding, except to the extent, if any, that any
such action is necessary to perfect, or continue the perfection of, the security
interest of the Issuer Secured Parties in the Indenture Collateral; provided
that any such successor shall also be the successor Trustee under Section 6.9.

               (b) Resignation. The Trust Collateral Agent and any successor
Trust Collateral Agent may resign at any time by so notifying the Issuer and the
Security Insurer; provided that the Trust Collateral Agent shall not so resign
unless it shall also resign as Trustee hereunder. 

               (c) Removal. The Trust Collateral Agent may be removed by the
Controlling Party at any time (and should be removed at any time that the
Trustee has been removed), with or without cause, by an instrument or concurrent
instruments in writing delivered to the Trust Collateral Agent, the other Issuer
Secured Party and the Issuer. A temporary successor may be removed at any time
to allow a successor Trust Collateral Agent to be appointed pursuant to
subsection (d) below. Any removal pursuant to the provisions of this subsection
(c) shall take effect only upon the date which is the latest of (i) the
effective date of the appointment of a successor Trust Collateral Agent and the
acceptance in writing by such successor Trust Collateral Agent of such
appointment and of its obligation to perform its duties hereunder in accordance
with the provisions hereof, and (ii) receipt by the Controlling Party of an
Opinion of Counsel to the effect described in Section 3.6. 

               (d) Acceptance by Successor. The Controlling Party shall have the
sole right to appoint each successor Trust Collateral Agent. Every temporary or
permanent successor Trust Collateral Agent appointed hereunder shall execute,
acknowledge and deliver to its predecessor and to the Trustee, each Issuer
secured Party and the Issuer an instrument in writing accepting such appointment
hereunder and the relevant predecessor shall execute, acknowledge and deliver
such other documents and instruments as will effectuate the delivery of all
Indenture Collateral to the successor Trust Collateral Agent, whereupon such
successor, without any further act, deed or conveyance, shall become fully
vested with all the estates, properties, rights, powers, duties and obligations
of its predecessor. Such predecessor shall, nevertheless, on the written request
of either Issuer Secured Party or the Issuer, execute and deliver an instrument
transferring to such successor all the estates, properties, rights and powers of
such predecessor hereunder. In the event that any instrument in writing from the
Issuer or an Issuer Secured Party is reasonably required by a successor Trust
Collateral Agent to more fully and certainly vest in such successor the estates,
properties, rights, powers, duties and obligations vested or intended to be
vested hereunder in the Trust Collateral Agent, any and all such written
instruments shall, at the request of the temporary or permanent successor Trust
Collateral Agent, be forthwith executed, acknowledged and delivered by the
Trustee or the Issuer, as the case may be. The designation of any successor
Trust Collateral Agent and the instrument or instruments removing any Trust
Collateral Agent and appointing a successor hereunder, together with all other
instruments provided for herein, shall be maintained with the records relating
to the Indenture Collateral and, to the extent required by applicable law, filed
or recorded by the successor Trust Collateral Agent in each place where such
filing or recording is necessary to effect the transfer of the Indenture
Collateral to the successor Trust Collateral Agent or to protect or continue the
perfection of the security interests granted hereunder.

               SECTION 6.18 Compensation. The Trust Collateral Agent shall not
be entitled to any compensation for the performance of its duties hereunder
other than the compensation it is entitled to receive in its capacity as
Trustee.

               SECTION 6.19 Representations and Warranties of the Trust
Collateral Agent. The Trust Collateral Agent represents and warrants to the
Issuer and to each Issuer Secured Party as follows:

               (a) Due Organization. The Trust Collateral Agent is a national
banking association and is duly authorized and licensed under applicable law to
conduct its business as presently conducted.

               (b) Corporate Power. The Trust Collateral Agent has all requisite
right, power and authority to execute and deliver this Indenture and to perform
all of its duties as Trust Collateral Agent hereunder. 

               (c) Due Authorization. The execution and delivery by the Trust
Collateral Agent of this Indenture and the other Transaction Documents to which
it is a party, and the performance by the Trust Collateral Agent of its duties
hereunder and thereunder, have been duly authorized by all necessary corporate
proceedings and no further approvals or filings, including any governmental
approvals, are required for the valid execution and delivery by the Trust
Collateral Agent, or the performance by the Trust Collateral Agent, of this
Indenture and such other Basic Documents. 

               (d) Valid and Binding Indenture. The Trust Collateral Agent has
duly executed and delivered this Indenture and each other Basic Document to
which it is a party, and each of this Indenture and each such other Basic
Document constitutes the legal, valid and binding obligation of the Trust
Collateral Agent, enforceable against the Trust Collateral Agent in accordance
with its terms, except as (i) such enforceability may be limited by bankruptcy,
insolvency, reorganization and similar laws relating to or affecting the
enforcement of creditors' rights generally and (ii) the availability of
equitable remedies may be limited by equitable principles of general
applicability.

               SECTION 6.20 Waiver of Setoffs. The Trust Collateral Agent
hereby expressly waives any and all rights of setoff that the Trust Collateral
Agent may otherwise at any time have under applicable law with respect to any
Trust Account and agrees that amounts in the Trust Accounts shall at all times
be held and applied solely in accordance with the provisions hereof.

               SECTION 6.21 Control by the Controlling Party. The Trust
Collateral Agent shall comply with notices and instructions given by the Issuer
only if accompanied by the written consent of the Controlling Party, except that
if any Event of Default shall have occurred and be continuing, the Trust
Collateral Agent shall act upon and comply with notices and instructions given
by the Controlling Party alone in the place and stead of the Issuer.

Insurer may request a copy of the list.

               SECTION 7.2 Preservation of Information; Communications to

               the Commission may from time to time by rules and regulations
               prescribe) which the Issuer may be required to file with the

                    (ii) file with the Trustee and the Commission in accordance

               by such rules and regulations; and 

                    (iii) supply to the Trustee (and the Trustee shall transmit

               summaries of any information, documents and reports required to
               be filed by the Issuer pursuant to clauses (i) and (ii) of this
               Section 7.3(a) as may be required by rules and regulations
               prescribed from time to time by the Commission.

within 60 days after each May 31, beginning with May 31, 1998, the Trustee shall
mail to each Noteholder as required by TIA ss. 313(c) a brief report dated as of
such date that complies with TIA ss. 313(a). The Trustee also shall comply with
TIA ss. 313(b).

               A copy of each report at the time of its mailing to Noteholders
shall be filed by the Trustee with the Commission and each stock exchange, if
any, on which the Notes are listed. The Issuer shall notify the Trustee if and
when the Notes are listed on any stock exchange.

                                  ARTICLE VIII

                      Accounts, Disbursements and Releases

               SECTION 8.1 Collection of Money. Except as otherwise expressly
provided herein, the Trustee may demand payment or delivery of, and shall
receive and collect, directly and without intervention or assistance of any
fiscal agent or other intermediary, all money and other property payable to or
receivable by the Trust Collateral Agent pursuant to this Indenture and the Sale
and Servicing Agreement. The Trustee shall apply all such money received by it,
or cause the Trust Collateral Agent to apply all money received by it as
provided in this Indenture and the Sale and Servicing Agreement. Except as
otherwise expressly provided in this Indenture or in the Sale and Servicing
Agreement, if any default occurs in the making of any payment or performance
under any agreement or instrument that is part of the Trust Estate, the Trustee
may take such action as may be appropriate to enforce such payment or
performance, including the institution and prosecution of appropriate
proceedings. Any such action shall be without prejudice to any right to claim a
Default or Event of Default under this Indenture and any right to proceed
thereafter as provided in Article V.

               SECTION 8.2 Release of Trust Estate.

               (a) Subject to the payment of its fees and expenses and other
amounts pursuant to Section 6.7, the Trust Collateral Agent may, and when
required by the provisions of this Indenture shall, execute instruments to
release property from the lien of this Indenture, in a manner and under
circumstances that are not inconsistent with the provisions of this Indenture.
No party relying upon an instrument executed by the Trust Collateral Agent as
provided in this Article VIII shall be bound to ascertain the Trust Collateral
Agent's authority, inquire into the satisfaction of any conditions precedent or
see to the application of any moneys.

               (b) The Trust Collateral Agent shall, at such time as there are
no Notes outstanding and all sums due the Trustee pursuant to Section 6.7 have
been paid, release any remaining portion of the Trust Estate that secured the
Notes from the lien of this Indenture and release to the Issuer or any other
Person entitled thereto any funds then on deposit in the Trust Accounts. The
Trustee shall release property from the lien of this Indenture pursuant to this
Section 8.2(b) only upon receipt of an Issuer Request accompanied by an
Officer's Certificate, an 

                                       54
<PAGE>
 
Opinion of Counsel and (if required by the TIA) Independent Certificates in
accordance with TIA ss.ss. 314(c) and 314(d)(1) meeting the applicable
requirements of Section 11.1.

               SECTION 8.3 Opinion of Counsel. The Trust Collateral Agent shall
receive at least seven days' notice when requested by the Issuer to take any
action pursuant to Section 8.2(a), accompanied by copies of any instruments
involved, and the Trustee shall also require as a condition to such action, an
Opinion of Counsel in form and substance satisfactory to the Trustee, stating
the legal effect of any such action, outlining the steps required to complete
the same, and concluding that all conditions precedent to the taking of such
action have been complied with and such action will not materially and adversely
impair the security for the Notes or the rights of the Noteholders in
contravention of the provisions of this Indenture; provided, however, that such
Opinion of Counsel shall not be required to express an opinion as to the fair
value of the Trust Estate. Counsel rendering any such opinion may rely, without
independent investigation, on the accuracy and validity of any certificate or
other instrument delivered to the Trustee in connection with any such action.

                                   ARTICLE IX

                             Supplemental Indentures

               SECTION 9.1 Supplemental Indentures Without Consent of
Noteholders.

               (a) Without the consent of the Holders of any Notes but with the
consent of the Security Insurer (unless an Insurer Default shall have occurred
and be continuing) and with prior notice to the Rating Agencies by the Issuer,
as evidenced to the Trustee, the Issuer and the Trustee, when authorized by an
Issuer Order, at any time and from time to time, may enter into one or more

Trust Indenture Act as in force at the date of the execution thereof), in form
satisfactory to the Trustee, for any of the following purposes:

                    (i) to correct or amplify the description of any property at
               any time subject to the lien of this Indenture, or better to
               assure, convey and confirm unto the Trust Collateral Agent any
               property subject or required to be subjected to the lien of this
               Indenture, or to subject to the lien of this Indenture additional
               property;

                    (ii) to evidence the succession, in compliance with the
               applicable provisions hereof, of another person to the Issuer,
               and the assumption by any such successor of the covenants of the
               Issuer herein and in the Notes contained; 

                    (iii) to add to the covenants of the Issuer, for the benefit
               of the Holders of the Notes, or to surrender any right or power
               herein conferred upon the Issuer; 

                    (iv) to convey, transfer, assign, mortgage or pledge any
               property to or with the Trust Collateral Agent; 

                    (v) to cure any ambiguity, to correct or supplement any
               provision herein or in any supplemental indenture which may be
               inconsistent with any other 

                                       55
<PAGE>
 
               provision herein or in any supplemental indenture or to make any
               other provisions with respect to matters or questions arising
               under this Indenture or in any supplemental indenture; provided
               that such action shall not adversely affect the interests of the
               Holders of the Notes;

                    (vi) to evidence and provide for the acceptance of the
               appointment hereunder by a successor trustee with respect to the
               Notes and to add to or change any of the provisions of this
               Indenture as shall be necessary to facilitate the administration
               of the trusts hereunder by more than one trustee, pursuant to the
               requirements of Article VI; or 

                    (vii) to modify, eliminate or add to the provisions of this
               Indenture to such extent as shall be necessary to effect the
               qualification of this Indenture under the TIA or under any
               similar federal statute hereafter enacted and to add to this
               Indenture such other provisions as may be expressly required by
               the TIA.

               The Trustee is hereby authorized to join in the execution of any
such supplemental indenture and to make any further appropriate agreements and
stipulations that may be therein contained.

               (b) The Issuer and the Trustee, when authorized by an Issuer 
Order, may, also without the consent of any of the Holders of the Notes but with
prior notice to the Rating Agencies by the Issuer, as evidenced to the Trustee,
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to, or changing in any manner or eliminating any of the
provisions of, this Indenture or of modifying in any manner the rights of the
Holders of the Notes under this Indenture; provided, however, that such action
shall not, as evidenced by an Opinion of Counsel, adversely affect in any
material respect the interests of any Noteholder.

               SECTION 9.2 Supplemental Indentures with Consent of Noteholders.
The Issuer and the Trustee, when authorized by an Issuer Order, also may, with
prior notice to the Rating Agencies, with the consent of the Security Insurer
(unless an Insurer Default shall have occurred and be continuing) and with the
consent of the Holders of not less than a majority of the outstanding Amount of
the Notes, by Act of such Holders delivered to the Issuer and the Trustee, enter
into an indenture or indentures supplemental hereto for the purpose of adding
any provisions to, or changing in any manner or eliminating any of the
provisions of, this Indenture or of modifying in any manner the rights of the
Holders of the Notes under this Indenture; provided, however, that, subject to
the express rights of the Security Insurer under the Basic Documents, no such
supplemental indenture shall, without the consent of the Holder of each
Outstanding Note affected thereby:

                    (i) change the date of payment of any installment of
               principal of or interest on any Note, or reduce the principal
               amount thereof, the interest rate thereon or the Redemption Price
               with respect thereto, change the provision of this Indenture
               relating to the application of collections on, or the proceeds of
               the sale of, the Trust Estate to payment of principal of or
               interest on the Notes, or change any place of payment where, or
               the coin or currency in which, any Note or the 

                                       56
<PAGE>
 
               interest thereon is payable, provided, that any change
               necessitated by the assumption by the Backup Servicer or other
               successor Servicer to the duties of AmeriCredit Financial
               Services, Inc., as Servicer, which results in the Distribution
               Date becoming the same date as the Insured Distribution Date
               shall not be considered an event which requires the consent of
               the Trustee, the Security Insurer or any Noteholder;

                    (ii) impair the right to institute suit for the enforcement
               of the provisions of this Indenture requiring the application of
               funds available therefor, as provided in Article V, to the
               payment of any such amount due on the Notes on or after the
               respective due dates thereof (or, in the case of redemption, on
               or after the Redemption Date); 

                    (iii) reduce the percentage of the Outstanding Amount of the
               Notes, the consent of the Holders of which is required for any
               such supplemental indenture, or the consent of the Holders of
               which is required for any waiver of compliance with certain
               provisions of this Indenture or certain defaults hereunder and
               their consequences provided for in this Indenture; 

                    (iv) modify or alter the provisions of the proviso to the
               definition of the term "Outstanding"; 

                    (v) reduce the percentage of the Outstanding Amount of the
               Notes required to direct the Trustee to direct the Issuer to sell
               or liquidate the Trust Estate pursuant to Section 5.4; 

                    (vi) modify any provision of this Section except to increase
               any percentage specified herein or to provide that certain
               additional provisions of this Indenture or the Basic Documents
               cannot be modified or waived without the consent of the Holder of
               each Outstanding Note affected thereby; 

                    (vii) modify any of the provisions of this Indenture in such
               manner as to affect the calculation of the amount of any payment
               of interest or principal due on any Note on any Distribution Date
               or any Insured Distribution Date (including the calculation of
               any of the individual components of such calculation) or to
               affect the rights of the Noteholders to the benefit of any
               provisions for the mandatory redemption of the Notes contained
               herein; or 

                    (viii) permit the creation of any lien ranking prior to or
               on a parity with the lien of this Indenture with respect to any
               part of the Trust Estate or, except as otherwise permitted or
               contemplated herein or in any of the Basic Documents, terminate
               the lien of this Indenture on any property at any time subject
               hereto or deprive the Holder of any Note of the security provided
               by the lien of this Indenture.

               The Trustee may determine whether or not any Notes would be
affected by any supplemental indenture and any such determination shall be
conclusive upon the Holders of all 

                                       57
<PAGE>
 
Notes, whether theretofore or thereafter authenticated and delivered hereunder.
The Trustee shall not be liable for any such determination made in good faith.

               It shall not be necessary for any Act of Noteholders under this
Section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such Act shall approve the substance thereof.

               Promptly after the execution by the Issuer and the Trustee of any
supplemental indenture pursuant to this Section, the Trustee shall mail to the
Holders of the Notes to which such amendment or supplemental indenture relates a
notice setting forth in general terms the substance of such supplemental
indenture. Any failure of the Trustee to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any
such supplemental indenture.

               SECTION 9.3 Execution of Supplemental Indentures. In executing,
or permitting the additional trusts created by, any supplemental indenture
permitted by this Article IX or the amendments or modifications thereby of the
trusts created by this Indenture, the Trustee shall be entitled to receive,
shall be fully protected in relying upon, an Opinion of Counsel stating that the
execution of such supplemental indenture is authorized or permitted by this
Indenture. The Trustee may, but shall not be obligated to, enter into any such
supplemental indenture that affects the Trustee's own rights, duties,
liabilities or immunities under this Indenture or otherwise.

               SECTION 9.4 Effect of Supplemental Indenture. Upon the execution
of any supplemental indenture pursuant to the provisions hereof, this Indenture
shall be and be deemed to be modified and amended in accordance therewith with
respect to the Notes affected thereby, and the respective rights, limitations of
rights, obligations, duties, liabilities and immunities under this Indenture of
the Trustee, the Issuer and the Holders of the Notes shall thereafter be
determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments, and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and
conditions of this Indenture for any and all purposes.

               SECTION 9.5 Conformity With Trust Indenture Act. Every amendment
of this Indenture and every supplemental indenture executed pursuant to this
Article IX shall conform to the requirements of the Trust Indenture Act as then
in effect so long as this Indenture shall then be qualified under the Trust
Indenture Act.

               SECTION 9.6 Reference in Notes to Supplemental Indentures. Notes
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article IX may, and if required by the Trustee shall, bear a
notation in form approved by the Trustee as to any matter provided for in such
supplemental indenture. If the Issuer or the Trustee shall so determine, new
Notes so modified as to conform, in the opinion of the Trustee and the Issuer,
to any such supplemental indenture may be prepared and executed by the Issuer
and authenticated and delivered by the Trustee in exchange for Outstanding
Notes.

                               Redemption of Notes

               SECTION 10.1 Redemption.

               (a) The Notes are subject to redemption in whole, but not in
part, at the direction of the Servicer or the Seller pursuant to Section 10.1(a)
of the Sale and Servicing Agreement, on any Distribution Date on which the
Servicer exercises its option to purchase the Trust Estate pursuant to said
Section 10.1(a), for a purchase price equal to the Redemption Price; provided,
however, that the Issuer has available funds sufficient to pay the Redemption
Price. The Servicer or the Issuer shall furnish the Security Insurer and the
Rating Agencies notice of such redemption. If the Notes are to be redeemed
pursuant to this Section 10.1(a), the Servicer or the Issuer shall furnish
notice of such election to the Trustee not later than 35 days prior to the
Redemption Date and the Issuer shall deposit with the Trustee in the Note
Distribution Account the Redemption Price of the Notes to be redeemed whereupon
all such Notes shall be due and payable on the Redemption Date upon the
furnishing of a notice complying with Section 10.2 to each Holder of Notes.

               (b) In the event that on the Distribution Date on which the
Funding Period ends (or on the Distribution Date on or immediately following the
last day of the Funding Period, if the Funding Period does not end on a
Distribution Date), the Pre-Funded Amount after giving effect to the purchase of
all Subsequent Receivables, including any such purchase on such Redemption Date,
the Notes will be redeemed in part, on a pro rata basis, in an aggregate
principal amount equal to the Class A-1 Prepayment Amount, the Class A-2
Prepayment Amount, the Class A-3 Prepayment Amount, the Class A-4 Prepayment
Amount and the Class A-5 Prepayment Amount. 

               (c) In the event that the assets of the Trust are sold pursuant
to Section 9.2 of the Trust Agreement, all amounts on deposit in the Note
Distribution Account shall be paid to the Noteholders up to the Outstanding
Amount of the Notes and all accrued and unpaid interest thereon. If amounts are
to be paid to Noteholders pursuant to this Section 10.1(c), the Servicer or the
Issuer shall, to the extent practicable, furnish notice of such event to the
Trustee not later than 45 days prior to the Redemption Date whereupon all such
amounts shall be payable on the Redemption Date.

               SECTION 10.2 Form of Redemption Notice.

               (a) Notice of redemption under Section 10.1(a) shall be given by
the Trustee by facsimile or by first-class mail, postage prepaid, transmitted or
mailed prior to the applicable Redemption Date to each Holder of Notes, as of
the close of business on the Record Date preceding the applicable Redemption
Date, at such Holder's address appearing in the Note Register.

               All notices of redemption shall state:

                    (i) the Redemption Date;

                                       59
<PAGE>
 
                    (ii) the Redemption Price;

                    (iii) that the Record Date otherwise applicable to such
               Redemption Date is not applicable and that payments shall be made
               only upon presentation and surrender of such Notes and the place
               where such Notes are to be surrendered for payment of the
               Redemption Price (which shall be the office or agency of the
               Issuer to be maintained as provided in Section 3.2); and 

                    (iv) that interest on the Notes shall cease to accrue on the
               Redemption Date.

               Notice of redemption of the Notes shall be given by the Trustee
in the name and at the expense of the Issuer. Failure to give notice of
redemption, or any defect therein, to any Holder of any Note shall not impair or
affect the validity of the redemption of any other Note.

               (b) Prior notice of redemption under Section 10.1(b) is not
required to be given to Noteholders.

               SECTION 10.3 Notes Payable on Redemption Date. The Notes to be
redeemed shall, following notice of redemption as required by Section 10.2 (in
the case of redemption pursuant to Section 10.1(a)), on the Redemption Date
become due and payable at the Redemption Price and (unless the Issuer shall
default in the payment of the Redemption Price) no interest shall accrue on the
Redemption Price for any period after the date to which accrued interest is
calculated for purposes of calculating the Redemption Price.

                                   ARTICLE XI

                                  Miscellaneous

               SECTION 11.1 Compliance Certificates and Opinions, etc.

               (a) Upon any application or request by the Issuer to the Trustee
or the Trust Collateral Agent to take any action under any provision of this
Indenture, the Issuer shall furnish to the Trustee or the Trust Collateral
Agent, as the case may be, and to the Security Insurer if the application or
request is made to the Trust Collateral Agent (i) an Officer's Certificate
stating that all conditions precedent, if any, provided for in this Indenture
relating to the proposed action have been complied with, (ii) an Opinion of
Counsel stating that in the opinion of such counsel all such conditions
precedent, if any, have been complied with and (iii) (if required by the TIA) an
Independent Certificate from a firm of certified public accountants meeting the
applicable requirements of this Section, except that, in the case of any such
application or request as to which the furnishing of such documents is
specifically required by any provision of this Indenture, no additional
certificate or opinion need be furnished.

               Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

                                       60
<PAGE>
 
                    (i) a statement that each signatory of such certificate or
               opinion has read or has caused to be read such covenant or
               condition and the definitions herein relating thereto;

                    (ii) a brief statement as to the nature and scope of the
               examination or investigation upon which the statements or
               opinions contained in such certificate or opinion are based;
               
                    (iii) a statement that, in the opinion of each such
               signatory, such signatory has made such examination or
               investigation as is necessary to enable such signatory to express
               an informed opinion as to whether or not such covenant or
               condition has been complied with; and 

                    (iv) a statement as to whether, in the opinion of each such
               signatory such condition or covenant has been complied with. 

               (b)  (i) Prior to the deposit of any Collateral or other property
or securities with the Trust Collateral Agent that is to be made the basis for
the release of any property or securities subject to the lien of this Indenture,
the Issuer shall, in addition to any obligation imposed in Section 11.1(a) or
elsewhere in this Indenture, furnish to the Trust Collateral Agent and the
Security Insurer an Officer's Certificate certifying or stating the opinion of
each person signing such certificate as to the fair value (within 90 days of
such deposit) to the Issuer of the Collateral or other property or securities to
be so deposited.

                    (ii) Whenever the Issuer is required to furnish to the Trust
               Collateral Agent and the Security Insurer an Officer's
               Certificate certifying or stating the opinion of any signer
               thereof as to the matters described in clause (i) above, the
               Issuer shall also deliver to the Trust Collateral Agent and the
               Security Insurer an Independent Certificate as to the same
               matters, if the fair value to the Issuer of the securities to be
               so deposited and of all other such securities made the basis of
               any such withdrawal or release since the commencement of the
               then-current fiscal year of the Issuer, as set forth in the
               certificates delivered pursuant to clause (i) above and this
               clause (ii), is 10% or more of the Outstanding Amount of the
               Notes, but such a certificate need not be furnished with respect
               to any securities so deposited, if the fair value thereof to the
               Issuer as set forth in the related Officer's Certificate is less
               than $25,000 or less than 1% percent of the Outstanding Amount of
               the Notes.

                    (iii) Other than with respect to the release of any
               Purchased Receivables or Liquidated Receivables, whenever any
               property or securities are to be released from the lien of this
               Indenture, the Issuer shall also furnish to the Trust Collateral
               Agent and the Security Insurer an Officer's Certificate
               certifying or stating the opinion of each person signing such
               certificate as to the fair value (within 90 days of such release)
               of the property or securities proposed to be released and stating
               that in the opinion of such person the proposed release will not
               impair the security under this Indenture in contravention of the
               provisions hereof. 

                                       61
<PAGE>
 
                    (iv) Whenever the Issuer is required to furnish to the
               Trustee and the Security Insurer an Officer's Certificate
               certifying or stating the opinion of any signer thereof as to the
               matters described in clause (iii) above, the Issuer shall also
               furnish to the Trust Collateral Agent and the Security Insurer an
               Independent Certificate as to the same matters if the fair value
               of the property or securities and of all other property other
               than Purchased Receivables and Defaulted Receivables, or
               securities released from the lien of this Indenture since the
               commencement of the then current calendar year, as set forth in
               the certificates required by clause (iii) above and this clause
               (iv), equals 10% or more of the Outstanding Amount of the Notes,
               but such certificate need not be furnished in the case of any
               release of property or securities if the fair value thereof as
               set forth in the related Officer's Certificate is less than
               $25,000 or less than 1 percent of the then Outstanding Amount of
               the Notes. 

                    (v) Notwithstanding Section 2.9 or any other provision of
               this Section, the Issuer may (A) collect, liquidate, sell or
               otherwise dispose of Receivables as and to the extent permitted
               or required by the Basic Documents and (B) make cash payments out
               of the Trust Accounts as and to the extent permitted or required
               by the Basic Documents.

               SECTION 11.2 Form of Documents Delivered to Trustee. In any case
where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified
by, or covered by the opinion of, only one such Person, or that they be so
certified or covered by only one document, but one such Person may certify or
give an opinion with respect to some matters and one or more other such Persons
as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents.

               Any certificate or opinion of an Authorized Officer of the Issuer
may be based, insofar as it relates to legal matters, upon a certificate or
opinion of, or representations by, counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the certificate or opinion or
representations with respect to the matters upon which his or her certificate or
opinion is based are erroneous. Any such certificate of an Authorized Officer or
Opinion of Counsel may be based, insofar as it relates to factual matters, upon
a certificate or opinion of, or representations by, an officer or officers of
the Servicer, the Seller or the Issuer, stating that the information with
respect to such factual matters is in the possession of the Servicer, the Seller
or the Issuer, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

               Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

               Whenever in this Indenture, in connection with any application or
certificate or report to the Trustee, it is provided that the Issuer shall
deliver any document as a condition of the granting of such application, or as
evidence of the Issuer's compliance with any term hereof, 

                                       62
<PAGE>
 
it is intended that the truth and accuracy, at the time of the granting of such
application or at the effective date of such certificate or report (as the case
may be), of the facts and opinions stated in such document shall in such case be
conditions precedent to the right of the Issuer to have such application granted
or to the sufficiency of such certificate or report. The foregoing shall not,
however, be construed to affect the Trustee's right to rely upon the truth and
accuracy of any statement or opinion contained in any such document as provided
in Article VI.

               SECTION 11.3 Acts of Noteholders.

               (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Noteholders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Noteholders in person or by agents
duly appointed in writing; and except as herein otherwise expressly provided
such action shall become effective when such instrument or instruments are
delivered to the Trustee, and, where it is hereby expressly required, to the
Issuer. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the
Noteholders signing such instrument or instruments. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Section 6.1) conclusive in
favor of the Trustee and the Issuer, if made in the manner provided in this
Section.

               (b) The fact and date of the execution by any person of any such
instrument or writing may be proved in any customary manner of the Trustee. 

               (c) The ownership of Notes shall be proved by the Note Register.

               (d) Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Holder of any Notes shall bind the Holder
of every Note issued upon the registration thereof or in exchange therefor or in
lieu thereof, in respect of anything done, omitted or suffered to be done by the
Trustee or the Issuer in reliance thereon, whether or not notation of such
action is made upon such Note.

               SECTION 11.4 Notices, etc., to Trustee, Issuer and Rating
Agencies. Any request, demand, authorization, direction, notice, consent,
waiver or Act of Noteholders or other documents provided or permitted by this
Indenture to be made upon, given or furnished to or filed with:

               (a) The Trustee by any Noteholder or by the Issuer shall be

overnight courier or mailed certified mail, return receipt requested and shall
be deemed to have been duly given upon receipt to the Trustee at its Corporate
Trust Office, or

               (b) The Issuer by the Trustee or by any Noteholder shall be
sufficient for every purpose hereunder if personally delivered, delivered by
overnight courier or mailed certified mail, return receipt requested and shall
deemed to have been duly given upon receipt to the Issuer addressed to:

by it from the Noteholders to the Trustee. 

               (c) The Security Insurer by the Issuer or the Trustee shall be
sufficient for any purpose hereunder if in writing and mailed by registered mail
or personally delivered or telexed or telecopied to the recipient as follows:

(In each case in which notice or other communication to the Security Insurer
refers to an Event of Default, a claim on the Note Policy or with respect to
which failure on the part of the Security Insurer to respond shall be deemed to
constitute consent or acceptance, then a copy of such notice or other
communication should also be sent to the attention of the General Counsel and
the Head--Financial Guaranty Group "URGENT MATERIAL ENCLOSED.")

               Notices required to be given to the Rating Agencies by the
Issuer, the Trustee or the Owner Trustee shall be in writing, personally
delivered, delivered by overnight courier or mailed certified mail, return
receipt requested to (i) in the case of Moody's, at the following address:
Moody's Investors Service, Inc., 99 Church Street, New York, New York 10004 and
(ii) in the case of S&P, at the following address: Standard & Poor's Ratings
Services, 26 Broadway (15th Floor), New York, New York 10004, Attention of Asset
Backed Surveillance Department; or as to each of the foregoing, at such other
address as shall be designated by written notice to the other parties.

               SECTION 11.5 Notices to Noteholders; Waiver. Where this
Indenture provides for notice to Noteholders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class, postage prepaid to each Noteholder affected by such
event, at his address as it appears on the Note Register, not later than the
latest date, and not earlier than the earliest date, prescribed for the giving
of such notice. In any case where notice to Noteholders is given by mail,
neither the failure to mail such notice nor any defect in any notice so mailed
to any particular Noteholder shall affect the sufficiency of such notice with
respect to other Noteholders, and any notice that is mailed in the manner here
in provided shall conclusively be presumed to have been duly given.

               Where this Indenture provides for notice in any manner, such
notice may be waived in writing by any Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Noteholders shall be 

                                       64
<PAGE>
 
filed with the Trustee but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such a waiver.

               In case, by reason of the suspension of regular mail service as a
result of a strike, work stoppage or similar activity, it shall be impractical
to mail notice of any event to Noteholders when such notice is required to be
given pursuant to any provision of this Indenture, then any manner of giving
such notice as shall be satisfactory to the Trustee shall be deemed to be a
sufficient giving of such notice.

               Where this Indenture provides for notice to the Rating Agencies,
failure to give such notice shall not affect any other rights or obligations
created hereunder, and shall not under any circumstance constitute a Default or
Event of Default.

               SECTION 11.6 [Reserved].

               SECTION 11.7 Conflict with Trust Indenture Act. If any provision
hereof limits, qualifies or conflicts with another provision hereof that is
required to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control.

               The provisions of TIA ss.ss. 310 through 317 that impose duties
on any person (including the provisions automatically deemed included herein
unless expressly excluded by this Indenture) are a part of and govern this
Indenture, whether or not physically contained herein.

               SECTION 11.8 Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

               SECTION 11.9 Successors and Assigns. All covenants and
agreements in this Indenture and the Notes by the Issuer shall bind its
successors and assigns, whether so expressed or not. All agreements of the
Trustee in this Indenture shall bind its successors. All agreements of the Trust
Collateral Agent in this Indenture shall bind its successors.

               SECTION 11.10 Separability. In case any provision in this
Indenture or in the Notes shall be invalid, illegal or unenforceable, the
validity, legality, and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

               SECTION 11.11 Benefits of Indenture. The Security Insurer and
its successors and assigns shall be a third-party beneficiary to the provisions
of this Indenture, and shall be entitled to rely upon and directly to enforce
such provisions of this Indenture so long as no Insurer Default shall have
occurred and be continuing. Nothing in this Indenture or in the Notes, express
or implied, shall give to any Person, other than the parties hereto and their
successors hereunder, and the Noteholders, and any other party secured
hereunder, and any other person with an Ownership interest in any part of the
Trust Estate, any benefit or any legal or equitable right, remedy or claim under
this Indenture. The Security Insurer may disclaim any of its rights and powers
under this Indenture (in which case the Trustee may exercise such right or power

                                       65
<PAGE>
 
hereunder), but not its duties and obligations under the Note Policy, upon
delivery of a written notice to the Trustee.

               SECTION 11.12 Legal Holidays. In any case where the date on
which any payment is due shall not be a Business Day, then (notwithstanding any
other provision of the Notes or this Indenture) payment need not be made on such
date, but may be made on the next succeeding Business Day with the same force

                                [REVERSE OF NOTE]

               This Note is one of a duly authorized issue of Notes of the
Issuer, designated as its Class A-1 5.629% Asset Backed Notes (herein called the
"Class A-1 Notes"), all issued under an Indenture dated as of May 11, 1998 (such
indenture, as supplemented or amended, is herein called the "Indenture"),
between the Issuer and Bank One, NA , as trustee (the "Trustee", which term
includes any successor Trustee under the Indenture) and as trust collateral
agent (the "Trust Collateral Agent"), which term includes any successor Trust
Collateral Agent) to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights and
obligations thereunder of the Issuer, the Trustee and the Holders of the Notes.
The Notes are subject to all terms of the Indenture. All terms used in this Note
that are defined in the Indenture, as supplemented or amended, shall have the
meanings assigned to them in or pursuant to the Indenture, as so supplemented or
amended.

               The Class A-1 Notes, the Class A-2 Notes, the Class A-3 Notes,
the Class A-4 Notes and the Class A-5 Notes (together, the "Notes") are and will
be equally and ratably secured by the collateral pledged as security therefor as
provided in the Indenture.

               Principal of the Class A-1 Notes will be payable on each
Distribution Date in an amount described on the face hereof. "Distribution Date"
means the fifth day of each month, or, if any such date is not a Business Day,
the next succeeding Business Day, provided that such day for payment shall in no
event be earlier than the third Business Day of the month, commencing June 5,
1998. The term "Distribution Date," shall be deemed to include the Final
Scheduled Distribution Date.

               As described above, the entire unpaid principal amount of this
Note shall be due and payable on the earlier of the Final Scheduled Distribution
Date and the Redemption Date, if any, pursuant to the Indenture. As described
above, a portion of the unpaid principal balance of this Note shall be due and
payable on the Redemption Date. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes shall be due and payable (i) on the date on which
an Event of Default shall have occurred and be continuing so long as an Insurer
Default shall not have occurred and be continuing or (ii) if an Insurer Default
shall have occurred and be continuing, on the date on which an Event of Default
shall have occurred and be continuing and the Trustee or the Holders of the
Notes representing at least 66-2/3% of the Outstanding Amount of the Notes have
declared the Notes to be immediately due and payable in the manner provided in
the Indenture. All principal payments on the Class A-1 Notes shall be made pro
rata to the Class A-1 Noteholders entitled thereto.

               Payments of interest on this Note due and payable on each
Distribution Date, together with the installment of principal, if any, to the
extent not in full payment of this Note, shall be made by check mailed to the
Person whose name appears as the Holder of this Note (or one or more Predecessor
Notes) on the Note Register as of the close of business on each Record Date,
except that with respect to Notes registered on the Record Date in the name of
the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.),
payments will be made by wire transfer in immediately available funds to the
account designated by such nominee. Such checks shall be mailed to the Person
entitled thereto at the address of such Person as it appears on the Note
Register as of the applicable Record Date without requiring that this Note be





                                     A-1-5
<PAGE>
 
submitted for notation of payment. Any reduction in the principal amount of this
Note (or any one or more Predecessor Notes) effected by any payments made on any
Distribution Date shall be binding upon all future Holders of this Note and of
any Note issued upon the registration of transfer hereof or in exchange hereof
or in lieu hereof, whether or not noted hereon. If funds are expected to be
available, as provided in the Indenture, for payment in full of the then
remaining unpaid principal amount of this Note on a Distribution Date, then the
Trustee, in the name of and on behalf of the Issuer, will notify the Person who
was the Holder hereof as of the Record Date preceding such Distribution Date by
notice mailed prior to such Distribution Date and the amount then due and
payable shall be payable only upon presentation and surrender of this Note at
the Trustee's principal Corporate Trust Office or at the office of the Trustee's
agent appointed for such purposes located in Columbus, Ohio.

               The Issuer shall pay interest on overdue installments of interest
at the Class A-1 Interest Rate to the extent lawful.

               As provided in the Indenture, the Notes may be redeemed (a) in
whole, but not in part, at the option of the Servicer (with the consent of the
Security Insurer under certain circumstances), on any Distribution Date on or
after the date on which the Pool Balance is less than or equal to 10% of the
Original Pool Balance, and (b) in part, on a pro rata basis, on the Distribution
Date on or immediately following the last day of the Funding Period.

               As provided in the Indenture and subject to certain limitations
set forth therein, the transfer of this Note may be registered on the Note
Register upon surrender of this Note for registration of transfer at the office
or agency designated by the Issuer pursuant to the Indenture, (i) duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to
the Trustee duly executed by, the Holder hereof or his attorney duly authorized
in writing, with such signature guaranteed by an "eligible guarantor
institution" meeting the requirements of the Note Registrar which requirements
include membership or participation in Securities Transfer Agents Medallion
Program ("Stamp") or such other "signature guarantee program" as may be
determined by the Note Registrar in addition to, or in substitution for, Stamp,
all in accordance with the Exchange Act, and (ii) accompanied by such other
documents as the Trustee may require, and thereupon one or more new Notes of
authorized denominations and in the same aggregate principal amount will be
issued to the designated transferee or transferees. No service charge will be
charged for any registration of transfer or exchange of this Note, but the
transferor may be required to pay a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any such registration
of transfer or exchange.

               Each Noteholder or Note Owner, by acceptance of a Note or, in the
case of a Note Owner, a beneficial interest in a Note covenants and agrees that
no recourse may be taken, directly or indirectly, with respect to the
obligations of the Issuer, the Owner Trustee or the Trustee on the Notes or
under the Indenture or any certificate or other writing delivered in connection
therewith, against (i) the Seller, the Servicer, the General Partner, the
Trustee or the Owner Trustee in its individual capacity, (ii) any owner of a
beneficial interest in the Issuer or (iii) any partner, owner, beneficiary,
agent, officer, director or employee of the Seller, the Servicer, the General
Partner, the Trustee or the Owner Trustee in its individual capacity, any holder
of a beneficial interest in the Issuer, the Seller, the Servicer, the General
Partner, the Owner Trustee or the Trustee or of any successor or assign of the
Seller, the Servicer, the

General Partner, the Trustee or the Owner Trustee in its individual capacity,
except as any such Person may have expressly agreed (it being understood that
the Trustee and the Owner Trustee have no such obligations in their individual
capacity) and except that any such partner, owner or beneficiary shall be fully
liable, to the extent provided by applicable law, for any unpaid consideration
for stock, unpaid capital contribution or failure to pay any installment or call
owing to such entity.

               Prior to the due presentment for registration of transfer of this
Note, the Issuer, the Trustee and the Security Insurer and any agent of the
Issuer, the Trustee or the Security Insurer may treat the Person in whose name
this Note (as of the day of determination or as of such other date as may be
specified in the Indenture) is registered as the owner hereof for all purposes,
whether or not this Note be overdue, and neither the Issuer, the Trustee nor any
such agent shall be affected by notice to the contrary.

               The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the rights of the Holders of the Notes under the
Indenture at any time by the Issuer with the consent of the Security Insurer and
of the Noteholders representing a majority of the Outstanding Amount of all
Notes at the time Outstanding. The Indenture also contains provisions permitting
the Noteholders representing specified percentages of the Outstanding Amount of
the Notes, on behalf of the Holders of all the Notes, to waive compliance by the
Issuer with certain provisions of the Indenture and certain past defaults under
the Indenture and their consequences. Any such consent or waiver by the Holder
of this Note (or any one of more Predecessor Notes) shall be conclusive and
binding upon such Holder and upon all future Holders of this Note and of any
Note issued upon the registration of transfer hereof or in exchange hereof or in
lieu hereof whether or not notation of such consent or waiver is made upon this
Note. The Indenture also permits the Trustee to amend or waive certain terms and
conditions set forth in the Indenture without the consent of Holders of the
Notes issued thereunder.

               The term "Issuer" as used in this Note includes any successor to
the Issuer under the Indenture.

               The Issuer is permitted by the Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the Trustee and
the Noteholders under the Indenture.

               The Notes are issuable only in registered form in denominations
as provided in the Indenture, subject to certain limitations therein set forth.

               This Note and the Indenture shall be construed in accordance with
the laws of the State of New York, without reference to its conflict of law
provisions, and the obligations, rights and remedies of the parties hereunder
and thereunder shall be determined in accordance with such laws.

               No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on

                                [REVERSE OF NOTE]

               This Note is one of a duly authorized issue of Notes of the
Issuer, designated as its Class A-2 Floating Rate Asset Backed Notes (herein
called the "Class A-2 Notes"), all issued under an Indenture dated as of May 11,
1998 (such indenture, as supplemented or amended, is herein called the
"Indenture"), between the Issuer and Bank One, NA, as trustee (the "Trustee",
which term includes any successor Trustee under the Indenture) and as trust
collateral agent (the "Trust Collateral Agent"), which term includes any
successor Trust Collateral Agent) to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights and obligations thereunder of the Issuer, the Trustee and the Holders of
the Notes. The Notes are subject to all terms of the Indenture. All terms used
in this Note that are defined in the Indenture, as supplemented or amended,
shall have the meanings assigned to them in or pursuant to the Indenture, as so
supplemented or amended.

               The Class A-1 Notes, the Class A-2 Notes, the Class A-3 Notes,
the Class A-4 Notes and the Class A-5 Notes (together, the "Notes") are and will
be equally and ratably secured by the collateral pledged as security therefor as
provided in the Indenture.

               Principal of the Class A-2 Notes will be payable on each
Distribution Date in an amount described on the face hereof. "Distribution Date"
means the fifth day of each month, or, if any such date is not a Business Day,
the next succeeding Business Day, provided, that such day for payment shall in
no event be earlier than the third Business Day of the month, commencing June 5,
1998. The term "Distribution Date," shall be deemed to include the Final
Scheduled Distribution Date.

               As described above, the entire unpaid principal amount of this
Note shall be due and payable on the earlier of the Final Scheduled Distribution
Date and the Redemption Date, if any, pursuant to the Indenture. As described
above, a portion of the unpaid principal balance of this Note shall be due and
payable on the Redemption Date. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes shall be due and payable (i) on the date on which
an Event of Default shall have occurred and be continuing so long as an Insurer
Default shall not have occurred and be continuing or (ii) if an Insurer Default
shall have occurred and be continuing, on the date on which an Event of Default
shall have occurred and be continuing and the Trustee or the Holders of the
Notes representing at least 66-2/3% of the Outstanding Amount of the Notes have
declared the Notes to be immediately due and payable in the manner provided in
the Indenture. All principal payments on the Class A-2 Notes shall be made pro
rata to the Class A-2 Noteholders entitled thereto.

               Payments of interest on this Note due and payable on each
Distribution Date, together with the installment of principal, if any, to the
extent not in full payment of this Note, shall be made by check mailed to the
Person whose name appears as the Holder of this Note (or one or more Predecessor
Notes) on the Note Register as of the close of business on each Record Date,
except that with respect to Notes registered on the Record Date in the name of
the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.),
payments will be made by wire transfer in immediately available funds to the
account designated by such nominee. Such checks shall be mailed to the Person
entitled thereto at the address of such Person as it appears on the Note
Register as of the applicable Record Date without requiring that this Note be






                                     A-2-5
<PAGE>
 
submitted for notation of payment. Any reduction in the principal amount of this
Note (or any one or more Predecessor Notes) effected by any payments made on any
Distribution Date shall be binding upon all future Holders of this Note and of
any Note issued upon the registration of transfer hereof or in exchange hereof
or in lieu hereof, whether or not noted hereon. If funds are expected to be
available, as provided in the Indenture, for payment in full of the then
remaining unpaid principal amount of this Note on a Distribution Date, then the
Trustee, in the name of and on behalf of the Issuer, will notify the Person who
was the Holder hereof as of the Record Date preceding such Distribution Date by
notice mailed prior to such Distribution Date and the amount then due and
payable shall be payable only upon presentation and surrender of this Note at
the Trustee's principal Corporate Trust Office or at the office of the Trustee's
agent appointed for such purposes located in Columbus, Ohio.

               The Issuer shall pay interest on overdue installments of interest
at the Class A-2 Interest Rate to the extent lawful.

               As provided in the Indenture, the Notes may be redeemed (a) in
whole, but not in part, at the option of the Servicer (with the consent of the
Security Insurer under certain circumstances), on any Distribution Date on or
after the date on which the Pool Balance is less than or equal to 10% of the
Original Pool Balance, and (b) in part, on a pro rata basis, on the Distribution
Date on or immediately following the last day of the Funding Period.

               As provided in the Indenture and subject to certain limitations
set forth therein, the transfer of this Note may be registered on the Note
Register upon surrender of this Note for registration of transfer at the office
or agency designated by the Issuer pursuant to the Indenture, (i) duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to
the Trustee duly executed by, the Holder hereof or his attorney duly authorized
in writing, with such signature guaranteed by an "eligible guarantor
institution" meeting the requirements of the Note Registrar which requirements
include membership or participation in Securities Transfer Agents Medallion
Program ("Stamp") or such other "signature guarantee program" as may be
determined by the Note Registrar in addition to, or in substitution for, Stamp,
all in accordance with the Exchange Act, and (ii) accompanied by such other
documents as the Trustee may require, and thereupon one or more new Notes of
authorized denominations and in the same aggregate principal amount will be
issued to the designated transferee or transferees. No service charge will be
charged for any registration of transfer or exchange of this Note, but the
transferor may be required to pay a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any such registration
of transfer or exchange.

               Each Noteholder or Note Owner, by acceptance of a Note or, in the
case of a Note Owner, a beneficial interest in a Note covenants and agrees that
no recourse may be taken, directly or indirectly, with respect to the
obligations of the Issuer, the Owner Trustee or the Trustee on the Notes or
under the Indenture or any certificate or other writing delivered in connection
therewith, against (i) the Seller, the Servicer, the General Partner, the
Trustee or the Owner Trustee in its individual capacity, (ii) any owner of a
beneficial interest in the Issuer or (iii) any partner, owner, beneficiary,
agent, officer, director or employee of the Seller, the Servicer, the General
Partner, the Trustee or the Owner Trustee in its individual capacity, any holder
of a beneficial interest in the Issuer, the Seller, the Servicer, the General
Partner, the Owner Trustee or the Trustee or of any successor or assign of the
Seller, the Servicer, the

General Partner, the Trustee or the Owner Trustee in its individual capacity,
except as any such Person may have expressly agreed (it being understood that
the Trustee and the Owner Trustee have no such obligations in their individual
capacity) and except that any such partner, owner or beneficiary shall be fully
liable, to the extent provided by applicable law, for any unpaid consideration
for stock, unpaid capital contribution or failure to pay any installment or call
owing to such entity.

               Prior to the due presentment for registration of transfer of this
Note, the Issuer, the Trustee and the Security Insurer and any agent of the
Issuer, the Trustee or the Security Insurer may treat the Person in whose name
this Note (as of the day of determination or as of such other date as may be
specified in the Indenture) is registered as the owner hereof for all purposes,
whether or not this Note be overdue, and neither the Issuer, the Trustee nor any
such agent shall be affected by notice to the contrary.

               The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the rights of the Holders of the Notes under the
Indenture at any time by the Issuer with the consent of the Security Insurer and
of the Noteholders representing a majority of the Outstanding Amount of all
Notes at the time Outstanding. The Indenture also contains provisions permitting
the Noteholders representing specified percentages of the Outstanding Amount of
the Notes, on behalf of the Holders of all the Notes, to waive compliance by the
Issuer with certain provisions of the Indenture and certain past defaults under
the Indenture and their consequences. Any such consent or waiver by the Holder
of this Note (or any one of more Predecessor Notes) shall be conclusive and
binding upon such Holder and upon all future Holders of this Note and of any
Note issued upon the registration of transfer hereof or in exchange hereof or in
lieu hereof whether or not notation of such consent or waiver is made upon this
Note. The Indenture also permits the Trustee to amend or waive certain terms and
conditions set forth in the Indenture without the consent of Holders of the
Notes issued thereunder.

               The term "Issuer" as used in this Note includes any successor to
the Issuer under the Indenture.

               The Issuer is permitted by the Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the Trustee and
the Noteholders under the Indenture.

               The Notes are issuable only in registered form in denominations
as provided in the Indenture, subject to certain limitations therein set forth.

               This Note and the Indenture shall be construed in accordance with
the laws of the State of New York, without reference to its conflict of law
provisions, and the obligations, rights and remedies of the parties hereunder
and thereunder shall be determined in accordance with such laws.

               No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on
this Note at the times, place, and rate, and in the coin or currency herein
prescribed.

Default under the Indenture, the Holder shall have no claim against any of the

submitted for notation of payment. Any reduction in the principal amount of this
Note (or any one or more Predecessor Notes) effected by any payments made on any
Distribution Date shall be binding upon all future Holders of this Note and of
any Note issued upon the registration of transfer hereof or in exchange hereof
or in lieu hereof, whether or not noted hereon. If funds are expected to be
available, as provided in the Indenture, for payment in full of the then
remaining unpaid principal amount of this Note on a Distribution Date, then the
Trustee, in the name of and on behalf of the Issuer, will notify the Person who
was the Holder hereof as of the Record Date preceding such Distribution Date by

Original Pool Balance, and (b) in part, on a pro rata basis, on the Distribution
Date on or immediately following the last day of the Funding Period.

               As provided in the Indenture and subject to certain limitations
set forth therein, the transfer of this Note may be registered on the Note

or agency designated by the Issuer pursuant to the Indenture, (i) duly endorsed

authorized denominations and in the same aggregate principal amount will be
issued to the designated transferee or transferees. No service charge will be
charged for any registration of transfer or exchange of this Note, but the
transferor may be required to pay a sum sufficient to cover any tax or other

                                [REVERSE OF NOTE]

               This Note is one of a duly authorized issue of Notes of the
Issuer, designated as its Class A-5 6.12% Asset Backed Notes (herein called the
"Class A-5 Notes"), all issued under an Indenture dated as of May 11, 1998 (such
indenture, as supplemented or amended, is herein called the "Indenture"),
between the Issuer and Bank One, NA, as trustee (the "Trustee", which term
includes any successor Trustee under the Indenture) and as trust collateral
agent (the "Trust Collateral Agent"), which term includes any successor Trust
Collateral Agent) to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights and
obligations thereunder of the Issuer, the Trustee and the Holders of the Notes.
The Notes are subject to all terms of the Indenture. All terms used in this Note
that are defined in the Indenture, as supplemented or amended, shall have the
meanings assigned to them in or pursuant to the Indenture, as so supplemented or
amended.

               The Class A-1 Notes, the Class A-2 Notes, the Class A-3 Notes,
the Class A-4 Notes and the Class A-5 Notes (together, the "Notes") are and will
be equally and ratably secured by the collateral pledged as security therefor as
provided in the Indenture.

               Principal of the Class A-5 Notes will be payable on each
Distribution Date in an amount described on the face hereof. "Distribution Date"
means the fifth day of each month, or, if any such date is not a Business Day,
the next succeeding Business Day, provided, that such day for payment shall in
no event be earlier than the third Business Day of the month, commencing June 5,
1998. The term "Distribution Date," shall be deemed to include the Final
Scheduled Distribution Date.

               As described above, the entire unpaid principal amount of this
Note shall be due and payable on the earlier of the Final Scheduled Distribution
Date and the Redemption Date, if any, pursuant to the Indenture. As described
above, a portion of the unpaid principal balance of this Note shall be due and
payable on the Redemption Date. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes shall be due and payable (i) on the date on which
an Event of Default shall have occurred and be continuing so long as an Insurer
Default shall not have occurred and be continuing or (ii) if an Insurer Default
shall have occurred and be continuing, on the date on which an Event of Default
shall have occurred and be continuing and the Trustee or the Holders of the
Notes representing at least 66-2/3% of the Outstanding Amount of the Notes have
declared the Notes to be immediately due and payable in the manner provided in
the Indenture. All principal payments on the Class A-5 Notes shall be made pro
rata to the Class A-5 Noteholders entitled thereto.

               Payments of interest on this Note due and payable on each
Distribution Date, together with the installment of principal, if any, to the
extent not in full payment of this Note, shall be made by check mailed to the
Person whose name appears as the Holder of this Note (or one or more Predecessor
Notes) on the Note Register as of the close of business on each Record Date,
except that with respect to Notes registered on the Record Date in the name of
the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.),
payments will be made by wire transfer in immediately available funds to the
account designated by such nominee. Such checks shall be mailed to the Person
entitled thereto at the address of such Person as it appears on the Note
Register as of the applicable Record Date without requiring that this Note be




                                     A-5-5
<PAGE>
 
submitted for notation of payment. Any reduction in the principal amount of this
Note (or any one or more Predecessor Notes) effected by any payments made on any
Distribution Date shall be binding upon all future Holders of this Note and of
any Note issued upon the registration of transfer hereof or in exchange hereof
or in lieu hereof, whether or not noted hereon. If funds are expected to be
available, as provided in the Indenture, for payment in full of the then
remaining unpaid principal amount of this Note on a Distribution Date, then the
Trustee, in the name of and on behalf of the Issuer, will notify the Person who
was the Holder hereof as of the Record Date preceding such Distribution Date by
notice mailed prior to such Distribution Date and the amount then due and
payable shall be payable only upon presentation and surrender of this Note at
the Trustee's principal Corporate Trust Office or at the office of the Trustee's
agent appointed for such purposes located in Columbus, Ohio.

               The Issuer shall pay interest on overdue installments of interest
at the Class A-5 Interest Rate to the extent lawful.

               As provided in the Indenture, the Notes may be redeemed (a) in
whole, but not in part, at the option of the Servicer (with the consent of the
Security Insurer under certain circumstances), on any Distribution Date on or
after the date on which the Pool Balance is less than or equal to 10% of the
Original Pool Balance, and (b) in part, on a pro rata basis, on the Distribution
Date on or immediately following the last day of the Funding Period.

               As provided in the Indenture and subject to certain limitations
set forth therein, the transfer of this Note may be registered on the Note
Register upon surrender of this Note for registration of transfer at the office
or agency designated by the Issuer pursuant to the Indenture, (i) duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to
the Trustee duly executed by, the Holder hereof or his attorney duly authorized
in writing, with such signature guaranteed by an "eligible guarantor
institution" meeting the requirements of the Note Registrar which requirements
include membership or participation in Securities Transfer Agents Medallion
Program ("Stamp") or such other "signature guarantee program" as may be
determined by the Note Registrar in addition to, or in substitution for, Stamp,
all in accordance with the Exchange Act, and (ii) accompanied by such other
documents as the Trustee may require, and thereupon one or more new Notes of
authorized denominations and in the same aggregate principal amount will be
issued to the designated transferee or transferees. No service charge will be
charged for any registration of transfer or exchange of this Note, but the
transferor may be required to pay a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any such registration
of transfer or exchange.

               Each Noteholder or Note Owner, by acceptance of a Note or, in the
case of a Note Owner, a beneficial interest in a Note covenants and agrees that
no recourse may be taken, directly or indirectly, with respect to the
obligations of the Issuer, the Owner Trustee or the Trustee on the Notes or
under the Indenture or any certificate or other writing delivered in connection
therewith, against (i) the Seller, the Servicer, the General Partner, the
Trustee or the Owner Trustee in its individual capacity, (ii) any owner of a
beneficial interest in the Issuer or (iii) any partner, owner, beneficiary,
agent, officer, director or employee of the Seller, the Servicer, the General
Partner, the Trustee or the Owner Trustee in its individual capacity, any holder
of a beneficial interest in the Issuer, the Seller, the Servicer, the General
Partner, the Owner Trustee or the Trustee or of any successor or assign of the
Seller, the Servicer, the 



                                     A-5-6
<PAGE>
 
General Partner, the Trustee or the Owner Trustee in its individual capacity,
except as any such Person may have expressly agreed (it being understood that
the Trustee and the Owner Trustee have no such obligations in their individual
capacity) and except that any such partner, owner or beneficiary shall be fully
liable, to the extent provided by applicable law, for any unpaid consideration
for stock, unpaid capital contribution or failure to pay any installment or call
owing to such entity.

               Prior to the due presentment for registration of transfer of this
Note, the Issuer, the Trustee and the Security Insurer and any agent of the
Issuer, the Trustee or the Security Insurer may treat the Person in whose name
this Note (as of the day of determination or as of such other date as may be
specified in the Indenture) is registered as the owner hereof for all purposes,
whether or not this Note be overdue, and neither the Issuer, the Trustee nor any
such agent shall be affected by notice to the contrary.

               The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the rights of the Holders of the Notes under the
Indenture at any time by the Issuer with the consent of the Security Insurer and
of the Noteholders representing a majority of the Outstanding Amount of all
Notes at the time Outstanding. The Indenture also contains provisions permitting
the Noteholders representing specified percentages of the Outstanding Amount of
the Notes, on behalf of the Holders of all the Notes, to waive compliance by the
Issuer with certain provisions of the Indenture and certain past defaults under
the Indenture and their consequences. Any such consent or waiver by the Holder
of this Note (or any one of more Predecessor Notes) shall be conclusive and
binding upon such Holder and upon all future Holders of this Note and of any
Note issued upon the registration of transfer hereof or in exchange hereof or in
lieu hereof whether or not notation of such consent or waiver is made upon this
Note. The Indenture also permits the Trustee to amend or waive certain terms and
conditions set forth in the Indenture without the consent of Holders of the
Notes issued thereunder.

               The term "Issuer" as used in this Note includes any successor to
the Issuer under the Indenture.

               The Issuer is permitted by the Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the Trustee and
the Noteholders under the Indenture.

               The Notes are issuable only in registered form in denominations
as provided in the Indenture, subject to certain limitations therein set forth.

               This Note and the Indenture shall be construed in accordance with
the laws of the State of New York, without reference to its conflict of law
provisions, and the obligations, rights and remedies of the parties hereunder
and thereunder shall be determined in accordance with such laws.

               No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on

               (e) No Violation. The consummation of the transactions
contemplated by this Agreement and the fulfillment of the terms hereof do not
conflict with, result in any breach of any of the terms and provisions of, or
constitute (with or without notice or lapse of time) a default under, the
certificate of incorporation or by-laws of the Depositor, or any material
indenture, agreement or other instrument to which the Depositor is a party or by
which it is bound; nor result in the creation or imposition of any Lien upon any

<PAGE>
 
the validity or enforceability of, this Agreement or any of the Basic Documents,
or (D) seeking to adversely affect the federal income tax or other federal,
state or local tax attributes of the Certificate.

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

               (a) to be bound by the terms and conditions of the Certificate of

set forth therein or herein, in all respects as if it were a signatory hereto.
This undertaking is made for the benefit of the Trust, the Owner Trustee and the

income tax purposes, it will, pursuant to Treasury Regulations promulgated under

income tax purposes, the Certificateholder will be treated as (i) owning all
assets owned by the Trust, (ii) having incurred all liabilities incurred by the
Trust, and (iii) all transactions between the Trust and the Certificateholder
will be disregarded.

               (b) In the event that the Trust has two equity owners for federal
income tax purposes, the Trust will be treated as a partnership. At any such
time that the Trust has two equity owners, this Agreement will be amended, in
accordance with Section 10.1 herein, and appropriate provisions will be added so
as to provide for treatment of the Trust as a partnership.

of the Owner Trustee. A Certificate bearing the manual or facsimile signatures

<PAGE>
 
such signatures shall have been affixed, authorized to sign on behalf of the
Trust, shall be validly issued and entitled to the benefit of this Agreement,

authorized prior to the authentication and delivery of such Certificate or did

               SECTION 3.3. Authentication of Certificate. Concurrently with

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

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

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

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

               A Certificate presented or surrendered for registration of
transfer or exchange shall be accompanied by a written instrument of transfer in
form satisfactory to the Owner Trustee and the Certificate Registrar duly
executed by the Certificateholder or his attorney duly authorized in writing,
with such signature guaranteed by an "eligible guarantor institution" meeting
the requirements of the Certificate Registrar, which requirements include

surrendered for registration of transfer or exchange shall be canceled and
subsequently disposed of by the Owner Trustee in accordance with its customary
practice.

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

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

               SECTION 3.6. Persons Deemed Certificateholders. Every Person by
virtue of becoming a Certificateholder in accordance with this Agreement shall
be deemed to be bound by the terms of this Agreement. Prior to due presentation
of the Certificate for registration of transfer, the Owner Trustee, the
Certificate Registrar and the Security Insurer and any agent of the Owner
Trustee, the Certificate Registrar and the Security Insurer, may treat the
person in whose name any Certificate shall be registered in the Certificate
Register as the owner of such Certificate for the purpose of receiving
distributions pursuant to the Sale and Servicing Agreement and for all other
purposes whatsoever, and none of the Owner Trustee, the Certificate Registrar or
the Security Insurer nor any agent of the Owner Trustee, the Certificate
Registrar or the Security Insurer shall be bound by any notice to the contrary.

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

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

               SECTION 3.9. ERISA Restrictions. The Certificate may not be
acquired by or for the account of (i) an employee benefit plan (as defined in
Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) that is subject to the provisions of Title I of ERISA, (ii) a plan
described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as
amended, or (iii) any entity whose underlying assets include plan assets by
reason of a plan's investment in the entity (each, a "Benefit Plan"). By
accepting and holding its beneficial ownership interest in its Certificate, the
Holder thereof shall be deemed to have represented and warranted that it is not
a Benefit Plan.

                                  ARTICLE IV.

                         Voting Rights and Other Actions

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

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

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

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

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

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

               SECTION 4.2. Action by Certificateholder with Respect to Certain
Matters. The Owner Trustee shall not have the power, except upon the direction
of the Certificateholder or the Security Insurer in accordance with the Basic
Documents, to (a) remove the Servicer under the Sale and Servicing Agreement
pursuant to Section 7.1 thereof or (b) except as expressly provided in the Basic
Documents, sell the Receivables after the termination of the Indenture. The
Owner Trustee shall take the actions referred to in the preceding sentence only
upon written instructions signed by the Certificateholder and the furnishing of
indemnification satisfactory to the Owner Trustee by the Certificateholder.

               SECTION 4.3. Restrictions on Certificateholder's Power.

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

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

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

                      Authority and Duties of Owner Trustee

               SECTION 5.1. General Authority.

               (a) The Owner Trustee is authorized and directed to execute and
deliver the Basic Documents to which the Trust is named as a party and each
certificate or other document attached as an exhibit to or contemplated by the
Basic Documents to which the Trust is named as a party and any amendment
thereto, in each case, in such form as the Depositor shall approve as evidenced
conclusively by the Owner Trustee's execution thereof, and on behalf of the
Trust, to direct the Indenture Trustee to authenticate and deliver Class A-1
Notes in the aggregate principal amount of $116,000,000, Class A-2 Notes in the
aggregate principal amount of $174,000,000, Class A-3 Notes in the aggregate
principal amount of $77,000,000, Class A-4 Notes in the aggregate principal
amount of $108,000,000 and Class A-5 Notes in the aggregate principal amount of
$50,000,000. In addition to the foregoing, the Owner Trustee is authorized, but
shall not be obligated, to take all actions required of the Trust pursuant to
the Basic Documents. The Owner Trustee is further authorized from time to time
to take such action as the Instructing Party recommends with respect to the
Basic Documents so long as such activities are consistent with the terms of the
Basic Documents.

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

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

               SECTION 5.3. Action upon Instruction.

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

               (b) The Owner Trustee shall not be required to take any action
hereunder or under any Basic Document if the Owner Trustee shall have reasonably
determined, or shall have been 

                                       12
<PAGE>
 
advised by counsel, that such action is likely to result in liability on the
part of the Owner Trustee or is contrary to the terms hereof or of any Basic
Document or is otherwise contrary to law.

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

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

               SECTION 5.4. No Duties Except as Specified in this Agreement or
in Instructions. The Owner Trustee shall not have any duty or obligation to
manage, make any payment with respect to, register, record, sell, dispose of, or
otherwise deal with the Owner Trust Estate, or to otherwise take or refrain from
taking any action under, or in connection with, any document contemplated hereby
to which the Owner Trustee is a party, except as expressly provided by the terms
of this Agreement or in any document or written instruction received by the
Owner Trustee pursuant to Section 5.3; and no implied duties or obligations
shall be read into this Agreement or any Basic Document against the Owner
Trustee. The Owner Trustee shall have no responsibility for filing any financing
or continuation statement in any public office at any time or to otherwise
perfect or maintain the perfection of any security interest or lien granted to
it hereunder or to prepare or file any Commission filing for the Trust or to
record this Agreement or any Basic Document. The Owner Trustee nevertheless
agrees that it will, at its own cost and expense, promptly take all action as
may be necessary to discharge any Liens on any part of the Owner Trust Estate
that result from actions by, or claims against, the Owner 

                                       13
<PAGE>
 
Trustee (solely in its individual capacity) and that are not related to the
ownership or the administration of the Owner Trust Estate.

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

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

                                  ARTICLE VI.

                          Concerning the Owner Trustee

               SECTION 6.1. Acceptance of Trusts and Duties. The Owner Trustee
accepts the trusts hereby created and agrees to perform its duties hereunder

Trustee also agrees to disburse all moneys actually received by it constituting

Agreement. The Owner Trustee shall not be answerable or accountable hereunder or
under any Basic Document under any circumstances, except (i) for its own willful

perform obligations expressly undertaken by it in the last sentence of Section

judgment made by a Responsible Officer of the Owner Trustee;

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

require the Owner Trustee to expend or risk funds or otherwise incur any
financial liability in the performance of any of its rights or powers hereunder
or under any Basic Document if the Owner Trustee shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured or provided to it; 

                                       14

indebtedness evidenced by or arising under any of the Basic Documents, including
the principal of and interest on the Notes; 

               (e) the Owner Trustee shall not be responsible for or in respect

validity of any of the Owner Trust Estate or for or in respect of the validity
or sufficiency of the Basic Documents, other than the certificate of
authentication on the Certificate, and the Owner Trustee shall in no event
assume or incur any liability, duty or obligation to the Security Insurer,
Trustee, Trust Collateral Agent, the Collateral Agent, any Noteholder or to any
Certificateholder, other than as expressly provided for herein and in the Basic
Documents; 

               (f) the Owner Trustee shall not be liable for the default or
misconduct of the Security Insurer, the Trustee, the Trust Collateral Agent or
the Servicer under any of the Basic Documents or otherwise and the Owner Trustee
shall have no obligation or liability to perform the obligations under this
Agreement or the Basic Documents that are required to be performed by the
Trustee under the Indenture or the Trust Collateral Agent or the Servicer under
the Sale and Servicing Agreement; and 

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

               SECTION 6.2. Furnishing of Documents. The Owner Trustee shall

<PAGE>
 
               (c) Neither the execution nor the delivery by it of this
Agreement, nor the consummation by it of the transactions contemplated hereby
nor compliance by it with any of the terms or provisions hereof will contravene
any federal or Delaware state law, governmental rule or regulation governing the
banking or trust powers of the Owner Trustee or any judgment or order binding on
it, or constitute any default under its charter documents or by-laws or any
indenture, mortgage, contract, agreement or instrument to which it is a party or
by which any of its properties may be bound. 

               SECTION 6.4. Reliance; Advice of Counsel.

               (a) The Owner Trustee shall incur no liability to anyone in
acting upon any signature, instrument, notice, resolution, request, consent,

it to be genuine and believed by it to be signed by the proper party or parties.
The Owner Trustee may accept a certified copy of a resolution of the board of
directors or other governing body of any corporate party as conclusive evidence
that such resolution has been duly adopted by such body and that the same is in
full force and effect. As to any fact or matter the method of the determination
of which is not specifically prescribed herein, the Owner Trustee may for all
purposes hereof rely on a certificate, signed by the president or any vice
president or by the treasurer, secretary or other authorized officers of the
relevant party, as to such fact or matter, and such certificate shall constitute
full protection to the Owner Trustee for any action taken or omitted to be taken
by it in good faith in reliance thereon.

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

               SECTION 6.5. Not Acting in Individual Capacity. Except as
provided in this Article VI, in accepting the trusts hereby created Bankers
Trust (Delaware) acts solely as Owner Trustee hereunder and not in its
individual capacity and all Persons having any claim against the Owner Trustee
by reason of the transactions contemplated by this Agreement or any Basic
Document shall look only to the Owner Trust Estate for payment or satisfaction
thereof.

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

representations as to the validity or sufficiency of this Agreement, of any
Basic Document or of the Certificate (other than the signature and
countersignature of the Owner Trustee on the Certificate) or the Notes, or of
any Receivable or related documents. The Owner Trustee shall at no time have any
responsibility or liability for or with respect to the legality, validity and

                                       16

enforceability of any Receivable, or the perfection and priority of any security
interest created by any Receivable in any Financed Vehicle or the maintenance of
any such perfection and priority, or for or with respect to the sufficiency of
the Owner Trust Estate or its ability to generate the payments to be distributed
to Certificateholder under this Agreement or the Noteholders under the
Indenture, including, without limitation: the existence, condition and ownership
of any Financed Vehicle; the existence and enforceability of any insurance
thereon; the existence and contents of any Receivable on any computer or other
record thereof; the validity of the assignment of any Receivable to the Trust or
of any intervening assignment; the completeness of any Receivable; the
performance or enforcement of any Receivable; the compliance by the Depositor,
the Servicer or any other Person with any warranty or representation made under
any Basic Document or in any related document or the accuracy of any such
warranty or representation or any action of the Trustee or the Servicer or any
subservicer taken in the name of the Owner Trustee.

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

               SECTION 6.8. Payments from Owner Trust Estate. All payments to
be made by the Owner Trustee under this Agreement or any of the Basic Documents
to which the Trust or the Owner Trustee is a party shall be made only from the
income and proceeds of the Owner Trust Estate and only to the extent that the
Owner Trust shall have received income or proceeds from the Owner Trust Estate
to make such payments in accordance with the terms hereof. Bankers Trust
(Delaware), or any successor thereto, in its individual capacity, shall not be

Documents to which the Trust or the Owner Trustee is a party.

               SECTION 6.9. Doing Business in Other Jurisdictions .
Notwithstanding anything contained to the contrary, neither Bankers Trust
(Delaware) or any successor thereto, nor the Owner Trustee shall be required to
take any action in any jurisdiction other than in the State of Delaware if the
taking of such action will, even after the appointment of a co-trustee or
separate trustee in accordance with Section 9.5 hereof, (i) require the consent
or approval or authorization or order of or the giving of notice to, or the
registration with or the taking of any other action in respect of, any state or
other governmental authority or agency of any jurisdiction other than the State
of Delaware; (ii) result in any fee, tax or other governmental charge under the
laws of the State of Delaware becoming payable by Bankers Trust (Delaware) (or
any successor thereto); or (iii) subject Bankers Trust (Delaware) (or any
successor thereto) to personal jurisdiction in any jurisdiction other than the
State of Delaware for causes of action arising from acts unrelated to the
consummation of the transactions by Bankers Trust (Delaware) (or any successor
thereto) or the Owner Trustee, as the case may be, contemplated hereby.

                          Compensation of Owner Trustee

               SECTION 7.1. Owner Trustee's Fees and Expenses. The Owner
Trustee shall receive as compensation for its services hereunder such fees as
have been separately agreed upon before the date hereof between AmeriCredit and
the Owner Trustee, and the Owner Trustee shall be entitled to be reimbursed by
the Depositor for its other reasonable expenses hereunder, including the
reasonable compensation, expenses and disbursements of such agents,
representatives, experts and counsel as the Owner Trustee may employ in
connection with the exercise and performance of its rights and its duties
hereunder and under the Basic Documents.

               SECTION 7.2. Indemnification. The Depositor shall be liable as
primary obligor for, and shall indemnify the Owner Trustee and its officers,
directors, successors, assigns, agents and servants (collectively, the
"Indemnified Parties") from and against, any and all liabilities, obligations,
losses, damages, taxes, claims, actions and suits, and any and all reasonable
costs, expenses and disbursements (including reasonable legal fees and expenses)
of any kind and nature whatsoever (collectively, "Expenses") which may at any
time be imposed on, incurred by, or asserted against the Owner Trustee or any
Indemnified Party in any way relating to or arising out of this Agreement, the
Basic Documents, the Owner Trust Estate, the administration of the Owner Trust
Estate or the action or inaction of the Owner Trustee hereunder, except only
that the Depositor shall not be liable for or required to indemnify the Owner
Trustee from and against Expenses arising or resulting from any of the matters
described in the third sentence of Section 6.1. The indemnities contained in
this Section and the rights under Section 7.1 shall survive the resignation or
termination of the Owner Trustee or the termination of this Agreement. In any
event of any claim, action or proceeding for which indemnity will be sought
pursuant to this Section, the Owner Trustee's choice of legal counsel shall be
subject to the approval of the Depositor which approval shall not be
unreasonably withheld.

               SECTION 7.3. Payments to the Owner Trustee. Any amounts paid to
the Owner Trustee pursuant to this Article VII shall be deemed not to be a part
of the Owner Trust Estate immediately after such payment.

               SECTION 7.4. Non-recourse Obligations. Notwithstanding anything
in this Agreement or any Basic Document, the Owner Trustee agrees in its
individual capacity and in its capacity as Owner Trustee for the Trust that all
obligations of the Trust to the Owner Trustee individually or as Owner Trustee
for the Trust shall be recourse to the Owner Trust Estate only and specifically
shall not be recourse to the assets of the Holder.

                                 ARTICLE VIII.

                         Termination of Trust Agreement

               SECTION 8.1. Termination of Trust Agreement.

               (a) This Agreement and the Trust shall terminate and be of no
further force or effect upon the latest of (i) the maturity or other liquidation
of the last Receivable (including the 

                                       18
<PAGE>
 
purchase by the Servicer at its option of the corpus of the Trust as described
in Section 10.1 of the Sale and Servicing Agreement) and the subsequent
distribution of amounts in respect of such Receivables as provided in the Basic
Documents, or (ii) the payment to the Certificateholder of all amounts required
to be paid to it pursuant to this Agreement and the payment to the Security
Insurer of all amounts payable or reimbursable to it pursuant to the Sale and
Servicing Agreement; provided, however, that the rights to indemnification under
Section 7.2 and the rights under Section 7.1 shall survive the termination of
the Trust. The Servicer shall promptly notify the Owner Trustee and the Security
Insurer of any prospective termination pursuant to this Section. The bankruptcy,
liquidation, dissolution, death or incapacity of the Certificateholder, shall
not (x) operate to terminate this Agreement or the Trust, nor (y) entitle the
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of all
or any part of the Trust or Owner Trust Estate nor (z) otherwise affect the
rights, obligations and liabilities of the parties hereto.

               (b) Neither the Depositor nor the Certificateholder shall be
entitled to revoke or terminate the Trust. 

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

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

               (d) Upon the winding up of the Trust and its termination, the
Owner Trustee shall cause the Certificate of Trust to be canceled by filing a
certificate of cancellation with the

Secretary of State in accordance with the provisions of Section 3810 of the
Business Trust Statute.

                                  ARTICLE IX.

             Successor Owner Trustees and Additional Owner Trustees

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

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

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

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

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

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

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

               SECTION 9.4. Merger or Consolidation of Owner Trustee. Any
corporation into which the Owner Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Owner Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Owner Trustee, shall be the successor of the Owner Trustee
hereunder, provided such corporation shall be eligible pursuant to Section 9.1,
without the execution or filing of any instrument or any further act on the part
of any of the parties hereto, anything herein to the contrary notwithstanding;
provided further that the Owner Trustee shall mail notice of such merger or
consolidation to the Rating Agencies.

               SECTION 9.5. Appointment of Co-Trustee or Separate Trustee .
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Owner Trust Estate or any Financed Vehicle may at the time be located,
the Servicer and the Owner Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Owner Trustee and the Security Insurer to act as co-trustee, jointly with
the 

                                       21
<PAGE>
 
Owner Trustee, or separate trustee or separate trustees, of all or any part
of the Owner Trust Estate, and to vest in such Person, in such capacity, such
title to the Trust, or any part thereof, and, subject to the other provisions of
this Section, such powers, duties, obligations, rights and trusts as the
Servicer and the Owner Trustee may consider necessary or desirable. If the
Servicer shall not have joined in such appointment within 15 days after the
receipt by it of a request so to do, the Owner Trustee subject, unless an
Insurer Default shall have occurred and be continuing, to the approval of the
Security Insurer (which approval shall not be unreasonably withheld) shall have
the power to make such appointment. No co-trustee or separate trustee under this
Agreement shall be required to meet the terms of eligibility as a successor
trustee pursuant to Section 9.1 and no notice of the appointment of any
co-trustee or separate trustee shall be required pursuant to Section 9.3.

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

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

               (ii) no trustee under this Agreement shall be personally liable
          by reason of any act or omission of any other trustee under this
          Agreement; and (iii) the Servicer and the Owner Trustee acting jointly
          may at any time accept the resignation of or remove any separate
          trustee or co-trustee.

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

               Any separate trustee or co-trustee may at any time appoint the
Owner Trustee, its agent or attorney-in-fact with full power and authority, to
the extent not prohibited by law, to do any lawful act under or in respect of
this Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all of

                                       22
<PAGE>
 
its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Owner Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

                                   ARTICLE X.

                                  Miscellaneous
                                                                           
               SECTION 10.1. Supplements and Amendments.

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

               (b) This Agreement may also be amended from time to time, with
the prior written consent of the Security Insurer (so long as an Insurer Default
shall not have occurred and be continuing) by the Depositor and the Owner
Trustee, with prior written notice to the Rating Agencies, to the extent such
amendment materially and adversely affects the interests of the Noteholders,
with the consent of the Noteholders evidencing not less than a majority of the
Outstanding Amount of the Notes and, the consent of the Certificateholder (which
consent of any Holder of a Certificate or Note given pursuant to this Section or
pursuant to any other provision of this Agreement shall be conclusive and
binding on such Holder) for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of this Agreement or of
modifying in any manner the rights of the Noteholders or the Certificateholder;
provided, however, that, subject to the express rights of the Security Insurer
under the Basic Documents, no such amendment shall (a) increase or reduce in any
manner the amount of, or accelerate or delay the timing of, collections of
payments on Receivables or distributions that shall be required to be made for
the benefit of the Noteholders or the Certificateholder or (b) reduce the
aforesaid percentage of the Outstanding Amount of the Notes and the Certificate
Balance required to consent to any such amendment, without the consent of the
Holders of all the outstanding Notes and the Certificateholder.

               Promptly after the execution of any such amendment or consent,
the Owner Trustee shall furnish written notification of the substance of such
amendment or consent to the Certificateholder, the Trustee and each of the
Rating Agencies.

               It shall not be necessary for the consent of Certificateholder,
the Noteholders or the Trustee pursuant to this Section to approve the
particular form of any proposed amendment or consent, but it shall be sufficient
if such consent shall approve the substance thereof. The manner of obtaining
such consents (and any other consents of the Certificateholder provided for in
this Agreement or in any other Basic Document) and of evidencing the
authorization of the execution thereof by Certificateholder shall be subject to
such reasonable requirements as the 

                                       23
<PAGE>
 
Owner Trustee may prescribe. Promptly after the execution of any amendment to
the Certificate of Trust, the Owner Trustee shall cause the filing of such
amendment with the Secretary of State.

               Prior to the execution of any amendment to this Agreement or the
Certificate of Trust, the Owner Trustee shall be entitled to receive and rely
upon an Opinion of Counsel stating that the execution of such amendment is
authorized or permitted by this Agreement and that all conditions precedent to
the execution and delivery of such amendment have been satisfied. The Owner
Trustee may, but shall not be obligated to, enter into any such amendment which
affects the Owner Trustee's own rights, duties or immunities under this
Agreement or otherwise.

               SECTION 10.2. No Legal Title to Owner Trust Estate in
Certificateholder. The Certificateholder shall not have legal title to any part
of the Owner Trust Estate. The Certificateholder shall be entitled to receive
distributions in accordance with Articles VIII. No transfer, by operation of law
or otherwise, of any right, title or interest of the Certificateholder to and in
its ownership interest in the Owner Trust Estate shall operate to terminate this
Agreement or the trusts hereunder or entitle any transferee to an accounting or
to the transfer to it of legal title to any part of the Owner Trust Estate.

               SECTION 10.3. Limitations on Rights of Others. The provisions of
this Agreement are solely for the benefit of the Owner Trustee, the Depositor,
the Certificateholder, the Servicer and, to the extent expressly provided
herein, the Security Insurer, the Trustee and the Noteholders, and nothing in
this Agreement, whether express or implied, shall be construed to give to any
other Person any legal or equitable right, remedy or claim in the Owner Trust
Estate or under or in respect of this Agreement or any covenants, conditions or
provisions contained herein.

other communication should also be sent to the attention of the General Counsel
and the Head-Financial Guaranty Group "URGENT MATERIAL ENCLOSED"); or, as to
each party, at such other address as shall be designated by such party in a

is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

               SECTION 10.6. Separate Counterparts. This Agreement may be
executed by the parties hereto in separate counterparts, each of which when so
executed and delivered shall be an original, but all such counterparts shall

assets, except as may be expressly set forth or contemplated in this Agreement,
the Certificate or the Basic Documents.

               SECTION 10.9. Headings. The headings of the various Articles and
Sections herein are for convenience of reference only and shall not define or

                                    not in its individual capacity but
                                    solely as Owner Trustee

Dated:                       By:

<PAGE>
 
                            (Reverse of Certificate)

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

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

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

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

        The obligations and responsibilities created by the Trust Agreement and
the Trust created thereby shall terminate upon the payment to the
Certificateholder of all amounts required to be paid to it pursuant to the Trust
Agreement and the Sale and Servicing Agreement and the disposition of all
property held as part of the Trust. The Servicer of the Receivables may at its
option purchase the corpus of the Trust at a price specified in the Sale and
Servicing Agreement, and such purchase of the Receivables and other property of
the Trust will effect early retirement 
<PAGE>
 
of the Certificate; however, such right of purchase is exercisable, subject to
certain restrictions, only as of the last day of any Monthly Period as of which
the Pool Balance is 10% or less of the Original Pool Balance. The Certificate is
also subject to mandatory prepayment, pro rata on the basis of the initial
Certificate Balance, on the Distribution Date on or immediately following the
last day of the Funding Period in the event that any portion of the Pre-Funded
Amount remains on deposit in the Pre-Funding Account after giving effect to the
purchase of all Subsequent Receivables, including any purchase of Subsequent
Receivables on such date. The aggregate principal amount of the Certificate to
be prepaid will be an amount equal to the Certificate Prepayment Amount.

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

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

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

repurchase. The sole remedy of the Issuer, the Owner Trustee, the Trust
Collateral Agent, the Trustee or the Noteholders with respect to a breach of
representations and warranties pursuant to Section 3.1 and the agreement
contained in this Section shall be the repurchase of Receivables pursuant to
this Section, subject to the conditions contained herein or to enforce the
obligation of AmeriCredit to the Seller to repurchase such Receivables pursuant
to the Purchase Agreement. Neither the Owner Trustee, the Trust Collateral Agent
nor the Trustee shall have a duty to conduct any affirmative investigation as to
the occurrence of any conditions requiring the repurchase of any Receivable
pursuant to this Section.

        In addition to the foregoing and notwithstanding whether the related
Receivable shall have been purchased by the Seller, the Seller shall indemnify
the Trust, the Trustee, the Backup Servicer, the Trust Collateral Agent,
Collateral Agent and the officers, directors, agents and employees thereof, the
Insurer, and the Noteholders against all costs, expenses, losses, damages,
claims and liabilities, including reasonable fees and expenses of counsel, which
may be asserted against or incurred by any of them as a result of third party
claims arising out of the events or facts giving rise to such breach.

                                       27

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

        SECTION 3.3. Custody of Receivables Files.

        (a) In connection with the sale, transfer and assignment of the
Receivables and the Other Conveyed Property to the Trust pursuant to this
Agreement and simultaneously with the execution and delivery of this Agreement,
the Trust Collateral Agent shall enter into the Custodian Agreement with the
Custodian, dated as of May 11, 1998, pursuant to which the Trust Collateral
Agent shall revocably appoint the Custodian, and the Custodian shall accept such
appointment, to act as the agent of the Trust Collateral Agent as custodian of
the following documents or instruments in its possession which shall be
delivered to the Custodian as agent of the Trust Collateral Agent on or before
the Closing Date (with respect to each Receivable):

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

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

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

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

        (b) Upon payment in full of any Receivable, the Servicer will notify the
Custodian pursuant to a certificate of an officer of the Servicer (which
certificate shall include a statement to the effect that all amounts received in
connection with such payments which are required to be deposited in the
Collection Account pursuant to Section 4.1 have been so deposited) and shall
request delivery of the Receivable and Receivable File to the Servicer. From
time to time as appropriate for servicing and enforcing any Receivable, the
Custodian shall, upon written request of an officer of the Servicer and delivery
to the Custodian of a receipt signed by such officer, cause the original
Receivable and the related Receivable File to be released to the Servicer. The
Servicer's receipt of a Receivable and/or Receivable File shall obligate the
Servicer to return the 

                                       28
<PAGE>
 
original Receivable and the related Receivable File to the Custodian when its
need by the Servicer has ceased unless the Receivable is repurchased as
described in Section 3.2 or 4.7.

                                   ARTICLE IV

                   Administration and Servicing of Receivables

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

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

        The Servicer is hereby authorized to commence, in it's own name or in
the name of the Trust, a legal proceeding to enforce a Receivable pursuant to
Section 4.3 or to commence or participate in any other legal proceeding
(including, without limitation, a bankruptcy proceeding) relating to or
involving a Receivable, an Obligor or a Financed Vehicle. If the Servicer
commences or participates in such a legal proceeding in its own name, the Trust
shall thereupon 

                                       29
<PAGE>
 
be deemed to have automatically assigned such Receivable to the Servicer solely
for purposes of commencing or participating in any such proceeding as a party or
claimant, and the Servicer is authorized and empowered by the Trust to execute
and deliver in the Servicer's name any notices, demands, claims, complaints,
responses, affidavits or other documents or instruments in connection with any
such proceeding. The Trust Collateral Agent and the Owner Trustee shall furnish
the Servicer with any limited powers of attorney and other documents which the
Servicer may reasonably request and which the Servicer deems necessary or
appropriate and take any other steps which the Servicer may deem necessary or
appropriate to enable the Servicer to carry out its servicing and administrative
duties under this Agreement.

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

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

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

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

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

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

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

                                       30
<PAGE>
 
                (iv) So long as an Insurer Default shall not have occurred and
        be continuing, the Servicer shall not amend or modify a Receivable
        (except as provided in Section 4.2(b) and this Section 4.2(c)) without
        the consent of the Insurer or a Note Majority (if an Insurer Default
        shall have occurred and be continuing).

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

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

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

        Notwithstanding any Lockbox Agreement, or any of the provisions of this
Agreement relating to the Lockbox Agreement, the Servicer shall remain obligated
and liable to the Trust, the Trust Collateral Agent and Noteholders for
servicing and administering the Receivables and the Other Conveyed Property in
accordance with the provisions of this Agreement without 

                                       31
<PAGE>
 
diminution of such obligation or liability by virtue thereof, provided, however,
that the foregoing shall not apply to any Backup Servicer for so long as a
Lockbox Bank is performing its obligations pursuant to the terms of a Lockbox
Agreement.

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

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

        SECTION 4.3. Realization upon Receivables.

        (a) Consistent with the standards, policies and procedures required by
this Agreement, the Servicer shall use its best efforts to repossess (or
otherwise comparably convert the ownership of) and liquidate any Financed
Vehicle securing a Receivable with respect to which the Servicer has determined
that payments thereunder are not likely to be resumed, as soon as is practicable
after default on such Receivable but in no event later than the date on which
all or any portion of a Scheduled 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 4.1, which practices and
procedures may include reasonable efforts to realize upon any recourse to
Dealers, the sale of the related Financed Vehicle at public or private sale, the
submission of claims under an Insurance Policy and other actions by the 

                                       32
<PAGE>
 
Servicer in order to realize upon such a Receivable. The foregoing is subject to
the provision that, in any case in which the Financed Vehicle shall have
suffered damage, the Servicer shall not expend funds in connection with any
repair or towards the repossession of such Financed Vehicle unless it shall
determine in its discretion that such repair and/or repossession shall increase
the proceeds of liquidation of the related Receivable by an amount greater than
the amount of such expenses. All amounts received upon liquidation of a Financed
Vehicle shall be remitted directly by the Servicer to the Collection Account
without deposit into any intervening account as soon as practicable, but in no
event later than the Business Day after receipt thereof. The Servicer shall be
entitled to recover all reasonable expenses incurred by it in the course of
repossessing and liquidating a Financed Vehicle into cash proceeds, but only out
of the cash proceeds of such Financed Vehicle, any deficiency obtained from the
Obligor or any amounts received from the related Dealer, which amounts in
reimbursement may be retained by the Servicer (and shall not be required to be
deposited as provided in Section 4.2(e)) to the extent of such expenses. The
Servicer shall pay on behalf of the Trust any personal property taxes assessed
on repossessed Financed Vehicles. The Servicer shall be entitled to
reimbursement of any such tax from Net Liquidation Proceeds with respect to such
Receivable.

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

        SECTION 4.4. Insurance.

        (a) The Servicer shall require, in accordance with its customary
servicing policies and procedures, that each Financed Vehicle be insured by the
related Obligor under the Insurance Policies referred to in Paragraph 24 of the
Schedule of Representations and Warranties and shall monitor the status of such
physical loss and damage insurance coverage thereafter, in accordance with its
customary servicing procedures. Each Receivable requires the Obligor to maintain
such physical loss and damage insurance, naming AmeriCredit and its successors
and assigns as additional insureds, and permits the holder of such Receivable to
obtain physical loss and damage insurance at the expense of the Obligor if the
Obligor fails to maintain such insurance. If the Servicer shall determine that
an Obligor has failed to obtain or maintain a physical loss and damage Insurance
Policy covering the related Financed Vehicle which satisfies the conditions set
forth in clause (i)(a) of such Paragraph 24 (including, without limitation,
during the repossession of such Financed Vehicle) the Servicer may enforce the
rights of the holder of the Receivable under the Receivable to require the
Obligor to obtain such physical loss and damage insurance in accordance with its
customary servicing policies and procedures. The Servicer may maintain a
vendor's single interest or other collateral protection insurance policy with
respect to all Financed 

                                       33
<PAGE>
 
Vehicles ("Collateral Insurance") which policy shall by its terms insure against
physical loss and damage in the event any Obligor fails to maintain physical
loss and damage insurance with respect to the related Financed Vehicle. All
policies of Collateral Insurance shall be endorsed with clauses providing for
loss payable to the Servicer. Costs incurred by the Servicer in maintaining such
Collateral Insurance shall be paid by the Servicer.

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

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

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

                                       34
<PAGE>
 
in its name or the name of the Trust and the Owner Trustee and/or the Trust
Collateral Agent for the benefit of the Noteholders.

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

        SECTION 4.5. Maintenance of Security Interests in Vehicles.

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

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

        AmeriCredit hereby agrees to pay all expenses related to such perfection
or reperfection and to take all action necessary therefor. In addition, prior to
the occurrence of an Insurance Agreement Event of Default, the Controlling Party
may instruct the Trust Collateral Agent and the Servicer to take or cause to be
taken such action as may, in the opinion of counsel to the Controlling Party, be
necessary to perfect or re-perfect the security interest in the Financed
Vehicles underlying the Receivables in the name of the Trust, including by
amending the title documents of such Financed Vehicles or by such other
reasonable means as may, in the opinion of counsel to the Controlling Party, be
necessary or prudent; provided, however, that if the Controlling Party requests
that the title documents be amended prior to the occurrence of an Insurance
Agreement Event of Default, the out-of-pocket expenses of the Servicer or the
Trust Collateral Agent in connection with such action shall be reimbursed to the
Servicer or the Trust Collateral Agent, as applicable, by the Controlling Party.
AmeriCredit and CP Funding hereby appoint the Trust Collateral Agent as their
attorney-in-fact to take any and all steps required to be 

                                       35
<PAGE>
 
performed by AmeriCredit or CP Funding pursuant to this Section 4.5(b) (it being
understood that and agreed that the Trust Collateral Agent shall have no
obligation to take such steps, except as pursuant to the Basic Documents to
which it is a party), including execution of certificates of title or any other
documents in the name and stead of AmeriCredit or CP Funding, and the Trust
Collateral Agent hereby accepts such appointment.

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

        (a) The Servicer covenants as follows:

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

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

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

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

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

        SECTION 4.7. Purchase of Receivables Upon Breach of Covenant. Upon
discovery by any of the Servicer, the Insurer, a Responsible Officer of the
Trust Collateral Agent, the Owner Trustee or a Responsible Officer of the
Trustee of a breach of any of the covenants set 

                                       36
<PAGE>
 
forth in Sections 4.5(a) or 4.6(a), the party discovering such breach shall give
prompt written notice to the others; provided, however, that the failure to give
any such notice shall not affect any obligation of AmeriCredit as Servicer under
this Section. As of the second Accounting Date following its discovery or
receipt of notice of any breach of any covenant set forth in Sections 4.5(a) or
4.6(a) which materially and adversely affects the interests of the Noteholders
or the Insurer in any Receivable (including any Liquidated Receivable) (or, at
AmeriCredit's election, the first Accounting Date so following) or the related
Financed Vehicle, AmeriCredit shall, unless such breach shall have been cured in
all material respects, purchase from the Trust the Receivable affected by such
breach and, on the related Determination Date, AmeriCredit shall pay the related
Purchase Amount. It is understood and agreed that the obligation of AmeriCredit
to purchase any Receivable (including any Liquidated Receivable) with respect to
which such a breach has occurred and is continuing shall, if such obligation is
fulfilled, constitute the sole remedy against AmeriCredit for such breach
available to the Insurer, the Noteholders, the Owner Trustee or the Trust
Collateral Agent; provided, however, that AmeriCredit shall indemnify the Trust,
the Backup Servicer, the Collateral Agent, the Insurer, the Owner Trustee, the
Trust Collateral Agent, the Trustee and the Noteholders against all costs,
expenses, losses, damages, claims and liabilities, including reasonable fees and
expenses of counsel, which may be asserted against or incurred by any of them as
a result of third party claims arising out of the events or facts giving rise to
such breach. This section shall survive the termination of this Agreement and
the earlier removal or resignation of the Trustee and/or the Trust Collateral
Agent and/or the Backup Servicer.

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

        SECTION 4.9. Preliminary Servicer's Certificate and Servicer's
Certificate.

        (a) No later than 10:00 am. Eastern time on each Preliminary
Determination Date, the Servicer shall deliver (facsimile delivery being
acceptable) to the Trustee, the Owner Trustee, the Trust Collateral Agent, the
Collateral Agent, the Backup Servicer, the Insurer, the Collateral Agent and
each Rating Agency a Preliminary Servicer's Certificate executed by a
Responsible Officer of the Servicer containing among other things, all
information necessary to enable the 

                                       37
<PAGE>
 
Trust Collateral Agent to give any notice required by Section 5.5(b) and to make
the distributions required by Sections 5.7(a) and 5.7(b).

        (b) No later than 10:00 am. Eastern time on each Determination Date, the
Servicer shall deliver (facsimile delivery being acceptable) to the Trustee, the
Owner Trustee, the Trust Collateral Agent, the Backup Servicer, the Insurer, the
Collateral Agent and each Rating Agency a Servicer's Certificate executed by a
Responsible Officer of the Servicer containing among other things, (i) all
information necessary to enable the Trust Collateral Agent to make any
withdrawal and deposit required by Section 5.5 and to make the distributions
required by Section 5.7(c), (ii) a listing of all Purchased Receivables and
Administrative Receivables purchased as of the related Accounting Date,
identifying the Receivables so purchased, (iii) all information necessary to
enable the Trust Collateral Agent to send the statements to Noteholders and the
Insurer required by Section 5.10, and (iv) all information necessary to enable
the Trust Collateral Agent to reconcile the aggregate cash flows, the Collection
Account for the related Collection Period, Distribution Date and Insured
Distribution Date, including the accounting required by Section 5.10.
Receivables purchased by the Servicer or by the Seller on the related Accounting
Date and each Receivable which became a Liquidated Receivable or which was paid
in full during the related Collection Period shall be identified by account
number (as set forth in the Schedule of Receivables). In addition to the
information set forth in the preceding sentence, the Servicer's Certificate
shall also contain the following information: (a) the Delinquency Ratio, Average
Delinquency Ratio, Cumulative Default Ratio and Cumulative Net Loss Ratio (as
such terms are defined in the Spread Account Agreement) for such Determination
Date; (b) whether any Trigger Event has occurred as of such Determination Date;
(c) whether any Trigger Event that may have occurred as of a prior Determination
Date is deemed cured as of such Determination Date; and (d) whether to the
knowledge of the Servicer an Insurance Agreement Event of Default has occurred.

        (c) In the event that the Distribution Date is the date described in
clause (y) of the definition of "Distribution Date" (i.e., if AmeriCredit is no
longer the Servicer), then the information required by the Preliminary
Servicer's Certificate shall be added to the information required by the
Servicer's Certificate, and the expanded Servicer's Certificate shall be
delivered as required by paragraph (b) above. 

        SECTION 4.10. Annual Statement as to Compliance, Notice of Servicer
Termination Event.

        (a) The Servicer shall deliver to the Trustee, the Owner Trustee, the
Trust Collateral Agent, the Backup Servicer, the Insurer and each Rating Agency,

year, if other than June 30) of each year, beginning on October 31, 1999, an
officer's certificate signed by any Responsible Officer of the Servicer, dated
as of June 30 (or other applicable date) of such year, stating that (i) a review
of the activities of the Servicer during the preceding 12-month period (or such
other period as shall have elapsed from the Closing Date to the date of the
first such certificate) and of its performance under this Agreement has been
made under such officer's supervision, and (ii) to such officer's knowledge,
based on such review, the Servicer has fulfilled all its obligations under this
Agreement throughout such period, or, if there has been a default in the
fulfillment of 

                                       38
<PAGE>
 
any such obligation, specifying each such default known to such officer and the
nature and status thereof.

        (b) The Servicer shall deliver to the Trustee, the Owner Trustee, the
Trust Collateral Agent, the Backup Servicer, the Insurer, the Collateral Agent,
and each Rating Agency, promptly after having obtained knowledge thereof, but in
no event later than two (2) Business Days thereafter, written notice in an
officer's certificate of any event which with the giving of notice or lapse of
time, or both, would become a Servicer Termination Event under Section 9.1(a).
The Seller or the Servicer shall deliver to the Trustee, the Owner Trustee, the
Trust Collateral Agent, the Backup Servicer, the Insurer, the Collateral Agent,
the Servicer or the Seller (as applicable) and each Rating Agency promptly after
having obtained knowledge thereof, but in no event later than two (2) Business
Days thereafter, written notice in an officer's certificate of any event which
with the giving of notice or lapse of time, or both, would become a Servicer
Termination Event under any other clause of Section 9.1. 

        SECTION 4.11. Annual Independent Accountants' Report.

        The Servicer shall cause a firm of nationally recognized independent
certified public accountants (the "Independent Accountants"), who may also
render other services to the Servicer or to the Seller, to deliver to the
Trustee, the Owner Trustee, the Trust Collateral Agent, the Backup Servicer, the
Insurer and each Rating Agency, on or before October 31 (or 120 days after the
end of the Servicer's fiscal year, if other than June 30) of each year,
beginning on October 31, 1999, with respect to the twelve months ended the
immediately preceding June 30 (or other applicable date) (or such other period
as shall have elapsed from the Closing Date to the date of such certificate), a
statement (the "Accountants' Report") addressed to the Board of Directors of the
Servicer, to the Trustee, the Owner Trustee, the Trust Collateral Agent, the
Backup Servicer and to the Insurer, to the effect that such firm has audited the
books and records of AmeriCredit Corp., in which the Servicer is included as a
consolidated subsidiary, and issued its report thereon in connection with the
audit report on the consolidated financial statements of 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 Seller and 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
agreed upon procedures to three randomly selected Servicer's Certificates
including the delinquency, default and loss statistics required to be specified
therein noting whether any exceptions or errors in the Servicer's Certificates
were found.

        SECTION 4.12. Access to Certain Documentation and Information Regarding
Receivables. The Servicer shall provide to representatives of the Trustee, the
Owner Trustee, the Trust Collateral Agent, the Backup Servicer and the Insurer
reasonable access to the documentation regarding the Receivables. In each case,
such access shall be afforded without charge but only upon reasonable request
and during normal business hours. Nothing in this Section shall affect the
obligation of the Servicer to observe any applicable law prohibiting disclosure
of information regarding the Obligors, and the failure of the Servicer to
provide access as provided in this Section as a result of such obligation shall
not constitute a breach of this Section.

                                       39
<PAGE>
 
        SECTION 4.13. Monthly Tape. On or before the Insured Distribution Date,
but in no event later than the seventh calendar day, of each month, the Servicer
will deliver to the Trust Collateral Agent and the Backup Servicer a computer
tape and a diskette (or any other electronic transmission acceptable to the
Trust Collateral Agent and the Backup Servicer) in a format acceptable to the
Trust Collateral Agent and the Backup Servicer containing the information with
respect to the Receivables as of the preceding Accounting Date necessary for
preparation of the Servicer's Certificate relating to the immediately preceding
Determination Date and necessary to determine the application of collections as
provided in Section 5.4. The Backup Servicer shall use such tape or diskette (or
other electronic transmission acceptable to the Trust Collateral Agent and the
Backup Servicer) to verify the Servicer's Certificate delivered by the Servicer,
and the Backup Servicer shall certify to the Controlling Party that it has
verified the Servicer's Certificate in accordance with this Section and shall
notify the Servicer and the Controlling Party of any discrepancies, in each
case, on or before the second Business Day following the Insured Distribution
Date. In the event that the Backup Servicer reports any discrepancies, the
Servicer and the Backup Servicer shall attempt to reconcile such discrepancies
prior to the next succeeding Distribution Date, but in the absence of a
reconciliation, the Servicer's Certificate shall control for the purpose of
calculations and distributions with respect to the next succeeding Distribution
Date. In the event that the Backup Servicer and the Servicer are unable to
reconcile discrepancies with respect to a Servicer's Certificate by the next
succeeding Distribution Date, the Servicer shall cause the Independent
Accountants, at the Servicer's expense, to audit the Servicer's Certificate and,
prior to the last day of the month after the month in which such Servicer's
Certificate was delivered, reconcile the discrepancies. The effect, if any, of
such reconciliation shall be reflected in the Preliminary Servicer's Certificate
for the next succeeding Distribution Date, and/or the Servicer's Certificate for
such next succeeding Determination Date. In addition, upon the occurrence of a
Servicer Termination Event the Servicer shall, if so requested by the
Controlling Party deliver to the Backup Servicer its Collection Records and its
Monthly Records within 15 days after demand therefor and a computer tape
containing as of the close of business on the date of demand all of the data
maintained by the Servicer in computer format in connection with servicing the
Receivables. Other than the duties specifically set forth in this Agreement, the
Backup Servicer shall have no obligations hereunder, including, without
limitation, to supervise, verify, monitor or administer the performance of the
Servicer. The Backup Servicer shall have no liability for any actions taken or
omitted by the Servicer.

        SECTION 4.13. Retention and Termination of Servicer. The Servicer
hereby covenants and agrees to act as such under this Agreement for an initial
term, commencing on the Closing Date and ending on June 30, 1998, which term
shall be extendible by the Controlling Party for successive quarterly terms
ending on each successive September 30, December 31 and March 31 (or, pursuant
to revocable written standing instructions from time to time to the Servicer and
the Trust Collateral Agent for any specified number of terms greater than one),
until the Notes and the Securities are paid in full. Each such notice (including
each notice pursuant to standing instructions, which shall be deemed delivered
at the end of successive quarterly terms for so long as such instructions are in
effect) (a "Servicer Extension Notice") shall be delivered by the Insurer to the
Trust Collateral Agent and the Servicer. The Servicer hereby agrees that, as of
the date hereof and upon its receipt of any such Servicer Extension Notice, the
Servicer shall become bound, for the initial term beginning on the Closing Date
and for the duration of the term covered by such Servicer Extension Notice, to
continue as the Servicer subject to and in accordance with the other provisions
of this Agreement. Until such time as an Insurer Default 

                                       40
<PAGE>
 
shall have occurred and be continuing the Trust Collateral Agent agrees that if
as of the fifteenth day prior to the last day of any term of the Servicer the
Trust Collateral Agent shall not have received any Servicer Extension Notice
from the Insurer, the Trust Collateral Agent will, within five days thereafter,
give written notice of such non-receipt to the Insurer and the Servicer.

        SECTION 4.14. Fidelity Bond and Errors and Omissions Policy. The
Servicer has obtained, and shall continue to maintain in full force and effect,
a Fidelity Bond and Errors and Omissions Policy of a type and in such amount as
is customary for servicers engaged in the business of servicing automobile
receivables.

                         Trust Accounts; Distributions;
                            Statements to Noteholders

        SECTION 5.1. Establishment of Trust Accounts.

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

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

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

        (b) Funds on deposit in the Collection Account, the Pre-Funding Account,
the Note Distribution Account and the Capitalized Interest Account
(collectively, the "Trust Accounts") and the Lockbox Accounts shall be invested
by the Trust Collateral Agent (or any custodian with respect to funds on deposit
in any such account) in Eligible Investments selected in writing by the Servicer
(pursuant to standing instructions or otherwise). All such Eligible Investments
shall be held by or on behalf of the Trust Collateral Agent for the benefit of
the Noteholders and the Insurer, as applicable. Other than as permitted by the
Rating Agencies and the Insurer, funds on deposit in any Account shall be
invested in Eligible Investments that will mature so that such funds will be
available at the close of business on the Business Day immediately preceding the
following Distribution Date or, if earlier, on the following Insured
Distribution Date. Funds deposited in a Trust Account on the day immediately
preceding a Distribution Date or an Insured 

                                       41
<PAGE>
 
Distribution Date upon the maturity of any Eligible Investments are not required
to be invested overnight. All Eligible Investments will be held to maturity.

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

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

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

        (f) (i)The Trust Collateral Agent shall possess all right, title and
interest in all funds on deposit from time to time in the Trust Accounts and in
all proceeds thereof (excluding all Investment Earnings on the Collection
Account) and all such funds, investments, proceeds and income shall be part of
the Owner Trust Estate. Except as otherwise provided herein, the Trust Accounts
shall be under the sole dominion and control of the Trust Collateral Agent for
the benefit of the Noteholders, as the case may be, and the Insurer. If, at any
time, any of the Trust Accounts ceases to be an Eligible Deposit Account, the
Trust Collateral Agent (or the Servicer on its behalf) shall within five
Business Days (or such longer period as to which each Rating Agency and the
Insurer may consent) establish a new Trust Account as an Eligible Deposit
Account and shall transfer any cash and/or any investments to such new Trust
Account. In connection with the foregoing, the Servicer agrees that, in the
event that any of the Trust Accounts are not accounts with the Trust Collateral
Agent, the Servicer shall notify the Trust Collateral Agent in writing promptly
upon any of such Trust Accounts ceasing to be an Eligible Deposit Account. 

                                       42
<PAGE>
 
        (ii) With respect to the Trust Account Property, the Trust Collateral
Agent agrees that:

                (A) any Trust Account Property that is held in deposit accounts
        shall be held solely in the Eligible Deposit Accounts; and, except as
        otherwise provided herein, each such Eligible Deposit Account shall be
        subject to the exclusive custody and control of the Trust Collateral
        Agent, and the Trust Collateral Agent shall have sole signature
        authority with respect thereto;

                (B) any Trust Account Property that constitutes Physical
        Property shall be delivered to the Trust Collateral Agent in accordance
        with paragraph (a) of the definition of "Delivery" and shall be held,
        pending maturity or disposition, solely by the Trust Collateral Agent or
        a financial intermediary (as such term is defined in Section 8-313(4) of
        the UCC) acting solely for the Trust Collateral Agent; 

                (C) any Trust Account Property that is a book-entry security
        held through the Federal Reserve System pursuant to Federal book-entry
        regulations shall be delivered in accordance with paragraph (b) of the
        definition of "Delivery" and shall be maintained by the Trust Collateral
        Agent, pending maturity or disposition, through continued book-entry
        registration of such Trust Account Property as described in such
        paragraph; and 

                (D) any Trust Account Property that is an "uncertificated
        security" under Article 8 of the UCC and that is not governed by clause
        (C) above shall be delivered to the Trust Collateral Agent in accordance
        with paragraph (c) of the definition of "Delivery" and shall be
        maintained by the Trust Collateral Agent, pending maturity or
        disposition, through continued registration of the Trust Collateral
        Agent's (or its nominee's) ownership of such security. 

        (g) The Servicer shall have the power, revocable by the Insurer or, with
the consent of the Insurer by the Trustee or by the Owner Trustee with the
consent of the Trustee, to instruct the Trust Collateral Agent to make
withdrawals and payments from the Trust Accounts for the purpose of permitting
the Servicer and the Trust Collateral Agent to carry out its respective duties
hereunder.

        SECTION 5.2. Capitalized Interest Account.

        (a) The Servicer shall cause the Trust Collateral Agent to establish and
maintain an Eligible Deposit Account (the "Capitalized Interest Account") with
the Trust Collateral Agent, bearing a designation clearly indicating that the
funds deposited therein are held in trust for the benefit of the Noteholders and
the Insurer.

        On or prior to the Closing Date, the Seller shall deposit an amount
equal to the Capitalized Interest Account Initial Deposit into the Capitalized
Interest Account.

        (b) (i)On the Distribution Dates occurring in June, July and August of
1998 the Trust Collateral Agent shall withdraw at the written direction of the
Servicer from the Capitalized 

                                       43
<PAGE>
 
Interest Account the Monthly Capitalized Interest Amount for such Distribution
Date and deposit such amount in the Collection Account as further provided in
Section 5.7.

                (ii) On the Distribution Dates occurring in June, July and
        August of 1998 the Servicer shall instruct the Trust Collateral Agent in
        writing to withdraw from the Capitalized Interest Account and pay to the
        Seller on such Distribution Date an amount equal to the Overfunded
        Capitalized Interest Amount for such Distribution Date. Any amounts
        remaining in the Capitalized Interest Account on the Distribution Date
        which immediately follows the end of the Funding Period after taking
        into account the transfer pursuant to Section 5.7(a)(i) shall be
        remitted by the Trust Collateral Agent to the Seller. Upon any such
        distributions to the Seller, the Noteholders, the Certificateholders and
        the Insurer will have no further rights in, or claims to, such amounts.

        SECTION 5.3. Certain Reimbursements to the Servicer. The Servicer will
be entitled to be reimbursed from amounts on deposit in the Collection Account
with respect to a Collection Period for amounts previously deposited in the
Collection Account but later determined by the Servicer to have resulted from
mistaken deposits or postings or checks returned for insufficient funds. The
amount to be reimbursed hereunder shall be paid to the Servicer on the related
Distribution Date pursuant to Section 5.7(b)(i) upon certification by the
Servicer of such amounts and the provision of such information to the Trust
Collateral Agent and the Insurer as may be necessary in the opinion of the
Insurer to verify the accuracy of such certification. In the event that the
Insurer has not received evidence satisfactory to it of the Servicer's
entitlement to reimbursement pursuant to this Section, the Insurer shall (unless

        SECTION 5.6. Additional Deposits.

        (a) The Servicer and the Seller, as applicable, shall deposit or cause

        SECTION 5.8. Note Distribution Account.

        (a) On each Distribution Date (based solely on the information contained
in the Preliminary Servicer's Certificate) and each Insured Distribution Date
(based solely on the information in the Servicer's Certificate), as applicable,
the Trust Collateral Agent shall distribute all amounts on deposit in the Note
Distribution Account to Noteholders in respect of the Notes to the extent of
amounts due and unpaid on the Notes for principal and interest in the following
amounts and in the following order of priority:

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

                (ii) any amounts deposited in the Note Distribution Account with
        respect to the Note Prepayment Amount, shall be distributed to the
        Holders of the Class A-1 Notes, the Class A-2 Notes, the Class A-3
        Notes, the Class A-4 Notes and the Class A-5 Notes, respectively, based
        upon the pro rata share as represented by the relative Outstanding
        Amount of each Class of Notes; provided, that if the aggregate remaining
        amount in the Pre-Funding Account is $100,000 or less, such amount will
        be applied exclusively to 

                                       47
<PAGE>
 
        reduce the outstanding principal balance of the Class of Notes then
        entitled to receive distributions of principal;
 
                (iii) to the Holders of the Class A-1 Notes, the Noteholders'
        Principal Distributable Amount and the Accelerated Principal Amount
        until the outstanding principal balance of the Class A-1 Notes is
        reduced to zero; 

                (iv) to the Holders of the Class A-2 Notes, the Noteholders'
        Principal Distributable Amount and the Accelerated Principal Amount
        until the outstanding principal balance of the Class A-2 Notes is
        reduced to zero; 

                (v) to the Holders of the Class A-3 Notes, the Noteholders'
        Principal Distributable Amount and the Accelerated Principal Amount
        until the outstanding principal balance of the Class A-3 Notes is
        reduced to zero; 

                (vi) to the Holders of the Class A-4 Notes, the Noteholders'
        Principal Distributable Amount and the Accelerated Principal Amount
        until the outstanding principal balance of the Class A-4 Notes is
        reduced to zero; and 

                (vii) to the Holders of the Class A-5 Notes, the Noteholders'
        Principal Distributable Amount and the Accelerated Principal Amount
        until the outstanding principal balance of the Class A-5 Notes is
        reduced to zero. 

        (b) On each Insured Distribution Date, the Trust Collateral Agent shall
send to each Noteholder the statement provided to the Trust Collateral Agent by
the Servicer pursuant to Section 5.10 hereof on such Insured Distribution Date.

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

        (d) Distributions required to be made to Noteholders on any Distribution
Date or any Insured Distribution Date shall be made to each Noteholder of record
on the preceding Record Date either by (i) wire transfer, in immediately
available funds, to the account of such Holder at a bank or other entity having
appropriate facilities therefor, if such Noteholder shall have 

                                       48
<PAGE>
 
provided to the Note Registrar appropriate written instructions at least five
Business Days prior to such Distribution Date and such Holder's Notes in the
aggregate evidence a denomination of not less than $1,000,000 or (ii) by check
mailed to such Noteholder at the address of such holder appearing in the Note
Register. Notwithstanding the foregoing, the final distribution in respect of
any Note (whether on the Final Scheduled Distribution Date or otherwise) will be
payable only upon presentation and surrender of such Note at the office or
agency maintained for that purpose by the Note Registrar pursuant to Section 2.4
of the Indenture.

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

        SECTION 5.9. Pre-Funding Account.

        (a) On the Closing Date, the Trust Collateral Agent will deposit, on
behalf of and at the written direction of the Seller, in the Pre-Funding Account
$100,001,572.67 from the proceeds of the sale of the Notes. On each Subsequent
Transfer Date, the Servicer shall instruct the Trust Collateral Agent in writing
to withdraw from the Pre-Funding Account (i) an amount equal to 97.5% of the
Principal Balance of the Subsequent Receivables transferred to the Issuer on
such Subsequent Transfer Date and to distribute such amount to or upon the order
of the Seller upon satisfaction of the conditions set forth in this Agreement
with respect to such transfer and (ii) an amount equal to the Subsequent Spread
Account Deposit on such Subsequent Transfer Date upon satisfaction of the
conditions set forth in this Agreement with respect to such transfer.

        (b) If the Pre-Funded Amount has not been reduced to zero on the date on
which the Funding Period ends after giving effect to any reductions in the
Pre-Funded Amount on such date, the Servicer shall instruct the Trust Collateral
Agent in writing to withdraw from the Pre-Funding Account on the Mandatory
Redemption Date the Pre-Funded Amount (exclusive of any Pre-Funding Earnings)
and deposit an amount equal to the Note Prepayment Amount in the Note
Distribution Account. 

        SECTION 5.10. Statements to Noteholders. On or prior to each
Distribution Date, the Trust Collateral Agent shall provide each Noteholder of
record (with a copy to the Insurer and the Rating Agencies) a statement setting
forth at least the following information as to the Notes to the extent
applicable:

                (i) the amount of such distribution allocable to principal of
        each Class of Notes;

                (ii) the amount of such distribution allocable to interest on or
        with respect to each Class of Notes; 

                (iii) the amount of such distribution payable out of amounts
        withdrawn from the Spread Account or pursuant to a claim on the Note
        Policy;

                (v) the aggregate outstanding principal amount of each Class of
        the Notes and the Note Pool Factor for each such Class after giving
        effect to payments allocated to principal reported under (i) above; 

                (vi) the amount of the Servicing Fee paid to the Servicer with
        respect to the related Collection Period and/or due but unpaid with
        respect to such Collection Period or prior Collection Periods, as the
        case may be; 

                (vii) the Noteholders' Interest Carryover Amount and the
        Noteholders' Principal Carryover Amount; 

                (viii) the amount of the aggregate Realized Losses, if any, for
        the second preceding Collection Period; 

                (ix) the aggregate Purchase Amounts for Receivables, if any,
        that were repurchased in such period; 

                (x) for Distribution Dates during the Funding Period (if any),
        the remaining Pre-Funded Amount; and 

                (xi) for the final Subsequent Transfer Date, the amount of any
        remaining Pre-Funded Amount that has not been used to fund the purchase
        of Subsequent Receivables and is passed through as principal to
        Noteholders. 

Each amount set forth pursuant to paragraph (i), (ii), (iii), (vi) and (vii)
above shall be expressed as a dollar amount per $1,000 of the initial principal
balance of the Notes (or Class thereof).

        SECTION 5.11. Optional Deposits by the Insurer. The Insurer shall at
any time, and from time to time, with respect to an Insured Distribution Date,
have the option (but shall not be required, except in accordance with the terms
of the Note Policy) to deliver amounts to the Trust Collateral Agent for deposit
into the Collection Account for any of the following purposes: (i) to provide
funds in respect of the payment of fees or expenses of any provider of services
to the Trust with respect to such Insured Distribution Date, or (ii) to include
such amount to the extent that without such amount a draw would be required to
be made on the Note Policy.

        SECTION 5.12. Determination of LIBOR.

        The Trust Collateral Agent will determine LIBOR for purposes of
calculating the Interest Rate for the Class A-2 Notes and the Class A-3 Notes
for each given Interest Period on the second business day prior to the
commencement of each Interest Periods (each, a "LIBOR Determination Date"). For
purposes of calculating LIBOR, a business day means a Business Day and a day on
which banking institutions in the City of London, England are not required or
authorized by law to be closed.

        "LIBOR" means, with respect to any Interest Period, the London interbank
offered rate for deposits in the U.S. dollars having a maturity of one month
commencing on the related LIBOR Determination Date (the "Index Maturity") which
appears on Telerate Page 3750 as of 11:00 a.m., London time, on such LIBOR
Determination Date. If such rate does not appear on 

                                       50
<PAGE>
 
the Telerate page 3750, the rate for that day will be determined on the basis of
the rate at which deposits in U.S. dollars, having the Index Maturity and in a
principal amount of not less than U.S. $1,000,000 are offered at approximately
11:00 a.m., London Time, on such LIBOR Determination Date to prime banks in the
London interbank market by the Reference Banks. The Trust Collateral Agent will
request the principal London office of each of such Reference Banks to provide a
quotation of its rate. If at least two such quotations are provided, the rate
for that day will be the arithmetic mean, rounded upward, if necessary, to the
nearest 1/100,000 of 1% (0.0000001), with five one-millionths of a percentage
point rounded upward, of all such quotations. If fewer than two such quotations
are provided, the rate for that day will be the arithmetic mean, rounded upward
of necessary to the nearest 1/100,000 of 1% (0.0000001), with five one-
millionths of a percentage point rounded upward, of the offered per annum rates
that one or more leading banks in New York City, selected by the Trust
Collateral Agent, are quoting as of approximately 11:00, Eastern time, on such
LIBOR Determination Date to leading European banks for United States dollar
deposits for the Index Maturity; provided that if the banks selected as
aforesaid are not quoting as mentioned in this sentence, LIBOR in effect for the
applicable Interest Period will be LIBOR in effect for the previous Interest
Period.

        "Telerate Page 3750" means the display page so designative on the Dow
Jones Telerate Services (or such other page as may replace that page on that
service for the purpose of displaying comparable name or rates).

        "Reference Banks" means four major banks in the London interbank market
selected by the Trust Collateral Agent.

                                   ARTICLE VI

                                 The Note Policy

        SECTION 6.1. Claims Under Note Policy.

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

        (b) Any notice delivered by the Trust Collateral Agent to the Insurer
pursuant to subsection 6.1(a) shall specify the Note Policy Claim Amount claimed
under the Note Policy and shall constitute a "Notice of Claim" under the Note
Policy. In accordance with the provisions of the Note Policy, the Insurer is
required to pay to the Trust Collateral Agent the Note Policy Claim Amount
properly claimed thereunder by 10:00 a.m., Eastern time, on the later of (i) the
third Business Day following receipt on a Business Day of the Notice of Claim,
and (ii) the 

                                       51
<PAGE>
 
applicable Insured Distribution Date. Any payment made by the Insurer under the
Note Policy shall be applied solely to the payment of the Notes, and for no
other purpose.

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

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

        (e) The Trust Collateral Agent shall be entitled to enforce on behalf of
the Noteholders the obligations of the Insurer under the Note Policy.
Notwithstanding any other provision of this Agreement or any Basic Document, the
Noteholders are not entitled to institute proceedings directly against the
Insurer. 

        SECTION 6.2. Preference Claims.

        (a) In the event that the Trust Collateral Agent has received a
certified copy of an order of the appropriate court that any Noteholders'
Interest Distributable Amount or Noteholders' Principal Distributable Amount
paid on a Note has been avoided in whole or in part as a preference payment
under applicable bankruptcy law, the Trust Collateral Agent shall so notify the
Insurer, shall comply with the provisions of the Note Policy to obtain payment
by the Insurer of such avoided payment, and shall, at the time it provides
notice to the Insurer, notify Holders of the Notes by mail that, in the event
that any Noteholder's payment is so recoverable, such Noteholder will be
entitled to payment pursuant to the terms of the Note Policy. The Trust
Collateral Agent shall furnish to the Insurer its records evidencing the
payments of principal of and interest on Notes, if any, which have been made by
the Trust Collateral Agent and subsequently recovered from Noteholders, and the
dates on which such payments were made. Pursuant to the terms of the Note
Policy, the Insurer will make such payment on behalf of the 

                                       52
<PAGE>
 
Noteholder to the receiver, conservator, debtor-in-possession or trustee in
bankruptcy named in the Order (as defined in the Note Policy) and not to the
Trust Collateral Agent or any Noteholder directly (unless a Noteholder has
previously paid such payment to the receiver, conservator, debtor-in-possession

Backup Servicer under this Agreement and, whether or not such assumption
agreement is executed, shall be the successor to the Backup Servicer under this
Agreement without the execution or filing of any paper or any further act on the
part of any of the parties to this Agreement, anything in this 

                                       61
<PAGE>
 
Agreement to the contrary notwithstanding; provided, however, that nothing
contained herein shall be deemed to release the Backup Servicer from any
obligation.

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

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

        (b) The Backup Servicer shall not be liable for any obligation of the
Servicer contained in this Agreement or for any errors of the Servicer contained
in any computer tape, certificate or other data or document delivered to the
Backup Servicer hereunder or on which the Backup Servicer must rely in order to
perform its obligations hereunder, and the Owner Trustee, the Trustee, the Trust
Collateral Agent, the Collateral Agent, the Backup Servicer, the Seller and the
Insurer and the Noteholders shall look only to the Servicer to perform such
obligations. The Backup Servicer, Trust Collateral Agent, the Trustee, the
Collateral Agent, the Owner Trustee and the Custodian shall have no
responsibility and shall not be in default hereunder or incur any liability for
any failure, error, malfunction or any delay in carrying out any of their
respective duties under this Agreement if such failure or delay results from the
Backup Servicer acting in accordance with information prepared or supplied by a
Person other than the Backup Servicer (or contractual agents) or the failure of
any such other Person to prepare or provide such information. The Backup
Servicer shall have no responsibility, shall not be in default and shall incur
no liability for (i) any act or failure to act of any third party (other than
its contractual agents), including the Servicer or the Controlling Party, (ii)
any inaccuracy or omission in a notice or communication received by the Backup
Servicer from any third party (other than its contractual agents), (iii) the
invalidity or unenforceability of any Receivable under applicable law, (iv) the
breach or inaccuracy of any representation or warranty made with respect to any
Receivable, or (v) the acts or omissions of any successor Backup Servicer. 

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

                                       62
<PAGE>
 
other parties hereto and the Noteholders except in the case of gross negligence
and willful misconduct by Bank One, NA.

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

        SECTION 8.6. Servicer and Backup Servicer Not to Resign. Subject to the
provisions of Section 8.3, neither the Servicer nor the Backup Servicer shall
resign from the obligations and duties imposed on it by this Agreement as
Servicer or Backup Servicer except upon a determination that by reason of a
change in legal requirements the performance of its duties under this Agreement
would cause it to be in violation of such legal requirements in a manner which
would have a material adverse effect on the Servicer or the Backup Servicer, as
the case may be, and the Insurer (so long as an Insurer Default shall not have
occurred and be continuing) or a Note Majority (if an Insurer Default shall have
occurred and be continuing) does not elect to waive the obligations of the
Servicer or the Backup Servicer, as the case may be, to perform the duties which
render it legally unable to act or to delegate those duties to another Person.
Any such determination permitting the resignation of the Servicer or Backup
Servicer shall be evidenced by an Opinion of Counsel to such effect delivered
and acceptable to the Trust Collateral Agent, the Owner Trustee and the Insurer
(unless an Insurer Default shall have occurred and be continuing). No
resignation of the Servicer shall become effective until, so long as no Insurer
Default shall have occurred and be continuing the Backup Servicer or an entity
acceptable to the Insurer shall have assumed the responsibilities and
obligations of the Servicer or, if an Insurer Default shall have occurred and be
continuing, the Backup Servicer or a successor Servicer that is an Eligible
Servicer shall have assumed the responsibilities and obligations of the
Servicer. No resignation of the Backup Servicer shall become effective until, so
long as no Insurer Default shall have occurred and be continuing, an entity
acceptable to the Insurer shall have assumed the responsibilities and
obligations of the Backup Servicer or, if an Insurer Default shall have occurred
and be continuing a Person that is an Eligible Servicer shall have assumed the
responsibilities and obligations of the Backup Servicer; provided, however, that
(i) in the event a successor Backup Servicer is not appointed within 60 days
after the Backup Servicer has given notice of its resignation and has provided
the Opinion of Counsel required by this Section, the Backup Servicer may
petition a court for its removal, (ii) the Backup Servicer may resign with the
written consent of the Insurer and (iii) if Bank One, NA resigns as the Trustee
under the Indenture it will no longer be the Backup Servicer.

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

        (c) Failure on the part of the Servicer duly to observe or perform any

or of the Insurer (unless an Insurer Default shall have occurred and be
continuing), and (ii) continues unremedied for a period of 30 days after
knowledge thereof by the Servicer or after the date on which written notice of
such failure, requiring the same to be remedied, shall have been given to the
Servicer by the Trust Collateral Agent or the Insurer (or, if an Insurer Default
shall have occurred and be continuing by any Noteholder); 

        (d) The entry of a decree or order for relief by a court or regulatory
authority having jurisdiction in respect of the Servicer in an involuntary case
under the federal bankruptcy laws, as now or hereafter in effect, or another
present or future, federal bankruptcy, insolvency or similar law, or appointing
a receiver, liquidator, assignee, trustee, custodian, sequestrator or other
similar official of the Servicer or of any substantial part of its property or

continuance of any such decree or order unstayed and in effect for a period of

federal or state bankruptcy, insolvency or similar law and such case is not
dismissed within 60 days; or 

        (e) The commencement by the Servicer of a voluntary case under the
federal bankruptcy laws, as now or hereafter in effect, or any other present or
future, federal or state, bankruptcy, insolvency or similar law, or the consent

liquidator, assignee, trustee, custodian, sequestrator or other similar official
of the Servicer or of any substantial part of its property or the making by the

corporate action by the Servicer in furtherance of any of the foregoing; or 

                                       64
<PAGE>
 
        (f) Any representation, warranty or statement of the Servicer made in
this Agreement or any certificate, report or other writing delivered pursuant
hereto shall prove to be incorrect in any material respect as of the time when
the same shall have been made, and the incorrectness of such representation,
warranty or statement has a material adverse effect on the Trust or the
Noteholders and, within 30 days after knowledge thereof by the Servicer or after
written notice thereof shall have been given to the Servicer by the Trust
Collateral Agent or the Insurer (or, if an Insurer Default shall have occurred
and be continuing, a Noteholder), the circumstances or condition in respect of
which such representation, warranty or statement was incorrect shall not have
been eliminated or otherwise cured; or 

        (g) So long as an Insurer Default shall not have occurred and be
continuing, the Insurer shall not have delivered a Servicer Extension Notice

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

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

        SECTION 9.2. Consequences of a Servicer Termination Event. If a
Servicer Termination Event shall occur and be continuing, the Insurer (or, if an
Insurer Default shall have occurred and be continuing either the Trust
Collateral Agent, (to the extent it has knowledge thereof) a Note Majority), by
notice given in writing to the Servicer (and to the Trust Collateral Agent if
given by the Insurer or the Noteholders) or by non-extension of the term of the
Servicer as referred to in Section 4.14 may terminate all of the rights and
obligations of the Servicer under this Agreement. On or after the receipt by the
Servicer of such written notice or upon termination of the term of the Servicer,
all authority, power, obligations and responsibilities of the Servicer under
this Agreement, whether with respect to the Notes, the Certificates or the Other
Conveyed Property or otherwise, automatically shall pass to, be vested in and
become obligations and responsibilities of the Backup Servicer (or such other
successor Servicer appointed by the Controlling Party); provided, however, that
the successor Servicer shall have no liability with respect to any obligation
which was required to be performed by the terminated Servicer prior to the date
that the successor Servicer becomes the Servicer or any claim of a third party
based on any alleged action or inaction of the terminated Servicer. The
successor Servicer is authorized and empowered by this Agreement to execute and
deliver, on behalf of the terminated Servicer, as attorney-in-fact or otherwise,
any and all documents and other instruments and to do or accomplish all other
acts or things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement of the Receivables
and the Other Conveyed Property and related documents to show the Trust as
lienholder or secured party on the related Lien Certificates, or otherwise. The
terminated Servicer agrees to cooperate with the successor Servicer in effecting
the termination of the responsibilities and rights of the terminated Servicer
under this Agreement, including, without limitation, the transfer to the
successor Servicer for administration by it of all cash amounts that shall at
the time be held by the terminated Servicer for deposit, or have been deposited
by the terminated Servicer, in the Collection Account or thereafter received
with respect to the Receivables and the delivery to the successor Servicer of
all Receivable Files, Monthly Records and Collection Records and a computer tape
in readable form as of the most recent Business Day 

                                       65
<PAGE>
 
containing all information necessary to enable the successor Servicer or a
successor Servicer to service the Receivables and the Other Conveyed Property.
If requested by the Controlling Party, the successor Servicer shall terminate
the Lockbox Agreement and direct the Obligors to make all payments under the
Receivables directly to the successor Servicer (in which event the successor
Servicer shall process such payments in accordance with Section 4.2(e)), or to a
lockbox established by the successor Servicer at the direction of the
Controlling Party, at the successor Servicer's expense. The terminated Servicer
shall grant the Trust Collateral Agent, the successor Servicer and the
Controlling Party reasonable access to the terminated Servicer's premises at the
terminated Servicer's expense.

        SECTION 9.3. Appointment of Successor.

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

        (b) The Controlling Party may exercise at any time its right to appoint
as Backup Servicer or as successor to the Servicer a Person other than the
Person serving as Backup Servicer at the time, and (without limiting its
obligations under the Note Policy) shall have no liability to the Trust
Collateral Agent, AmeriCredit, CP Funding, the Seller, the Person then serving
as Backup Servicer, any Noteholders or any other Person if it does so.
Notwithstanding the above, if the Backup Servicer shall be legally unable or
unwilling to act as Servicer, and an Insurer Default shall have occurred and be
continuing, the Backup Servicer, the Trust Collateral Agent or a Note Majority
may petition a court of competent jurisdiction to appoint any Eligible Servicer
as the successor to the Servicer. Pending appointment pursuant to the preceding
sentence, the Backup Servicer shall act as successor Servicer unless it is
legally unable to do so, in which event the outgoing Servicer shall continue to
act as Servicer until a successor has been appointed and accepted such
appointment. Subject to Section 8.6, no provision of this Agreement shall be
construed as relieving the Backup Servicer of its obligation to succeed as
successor Servicer upon the termination of the Servicer pursuant to Section 9.2,
the resignation of the Servicer pursuant to Section 8.6 or the non-extension of
the servicing term of the Servicer, as referred to in Section 4.14. If upon the
termination of the Servicer pursuant to Section 9.2 or the resignation of the
Servicer pursuant to Section 8.6, the Controlling Party appoints a successor
Servicer other than the Backup Servicer, the Backup Servicer shall not be
relieved of its duties as Backup Servicer hereunder. 

                                       66
<PAGE>
 
        (c) Any successor Servicer shall be entitled to such compensation
(whether payable out of the Collection Account or otherwise) as the Servicer
would have been entitled to under this Agreement if the Servicer had not
resigned or been terminated hereunder. If any successor Servicer is appointed as
a result of the Backup Servicer's refusal (in breach of the terms of this
Agreement) to act as Servicer although it is legally able to do so, the Insurer
and such successor Servicer may agree on reasonable additional compensation to
be paid to such successor Servicer by the Backup Servicer, which additional
compensation shall be paid by such breaching Backup Servicer in its individual
capacity and solely out of its own funds provided, however, it being understood
and agreed that the Insurer shall give prior notice to the Backup Servicer with
respect to the appointment of such successor and the payment of additional
compensation, if any. If any successor Servicer is appointed for any reason
other than the Backup Servicer's refusal to act as Servicer although legally
able to do so, the Insurer and such successor Servicer may agree on additional
compensation to be paid to such successor Servicer, which additional
compensation shall be payable as provided in the Spread Account Agreement and
shall in no event exceed $150,000. In addition, any successor Servicer shall be
entitled, as provided in the Spread Account Agreement, to reasonable transition
expenses incurred in acting as successor Servicer.

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

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

                                   Termination

        SECTION 10.1. Optional Purchase of All Receivables.

        (a) On the last day of any Collection Period as of which the Pool
Balance shall be less than or equal to 10% of the Original Pool Balance, the
Servicer and the Seller each shall have the option to purchase the Owner Trust
Estate, other than the Trust Accounts (with the consent of the Insurer if such
purchase would result in a claim on the Note Policy or would result in any
amount owing to the Insurer under the Insurance Agreement remaining unpaid);
provided, however, that the amount to be paid for such purchase (as set forth in
the following sentence) shall be sufficient to pay the full amount of principal,
premium, if any, and interest then due and payable on the Notes and the
Certificates. To exercise such option, the Servicer or the Seller, as the case
may be, shall deposit pursuant to Section 5.6 in the Collection Account an
amount equal to the aggregate Purchase Amount for the Receivables (including
Liquidated Receivables), plus the 

                                       67
<PAGE>
 
appraised value of any other property held by the Trust, such value to be
determined by an appraiser mutually agreed upon by the Servicer, the Insurer and
the Trust Collateral Agent, and shall succeed to all interests in and to the
Trust.

        (b) Upon any sale of the assets of the Trust pursuant to Section 8.1 of
the Trust Agreement, the Servicer shall instruct the Trust Collateral Agent to
deposit the proceeds from such sale after all payments and reserves therefrom
(including the expenses of such sale) have been made (the "Insolvency Proceeds")
in the Collection Account. 

        (c) Notice of any termination of the Trust shall be given by the
Servicer to the Owner Trustee, the Trustee, the Collateral Agent, the Backup
Servicer, the Trust Collateral Agent, the Insurer and the Rating Agencies as
soon as practicable after the Servicer has received notice thereof. 

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

        SECTION 11.1. Administrative Duties.

        (a) Duties with Respect to the Indenture. The Servicer shall perform all
its duties and the duties of the Issuer under the Indenture. In addition, the
Servicer shall consult with the Owner Trustee as the Servicer deems appropriate
regarding the duties of the Issuer under the Indenture. The Servicer shall
monitor the performance of the Issuer and shall advise the Owner Trustee when
action is necessary to comply with the Issuer's duties under the Indenture. The
Servicer shall prepare for execution by the Issuer or shall cause the
preparation by other appropriate Persons of all such documents, reports,
filings, instruments, certificates and opinions as it shall be the duty of the
Issuer to prepare, file or deliver pursuant to the Indenture. In furtherance of
the foregoing, the Servicer shall take all necessary action that is the duty of
the Issuer to take pursuant to the Indenture, including, without limitation,
pursuant to Sections 2.7, 3.5, 3.6, 3.7, 3.9, 3.10, 3.17, 5.1, 5.4, 7.3, 8.3,

        (b) Duties with Respect to the Issuer.

                (i) In addition to the duties of the Servicer set forth in this
        Agreement or any of the Basic Documents, the Servicer shall perform such
        calculations and shall prepare for execution by the Issuer or the Owner
        Trustee or shall cause the preparation by other appropriate Persons of
        all such documents, reports, filings, instruments, certificates and
        opinions as it shall be the duty of the Issuer or the Owner Trustee to
        prepare, file or deliver pursuant to this Agreement or any of the Basic
        Documents or under state and federal tax and securities laws, and at the
        request of the Owner Trustee shall take all appropriate action that it
        is the duty of the Issuer to take pursuant to this Agreement or any of
        the Basic Documents, including, without limitation, pursuant to Sections
        2.6 and 

                                       68
<PAGE>
 
        2.11 of the Trust Agreement. In accordance with the directions of the
        Issuer or the Owner Trustee, the Servicer shall administer, perform or
        supervise the performance of such other activities in connection with
        the Collateral (including the Basic Documents) as are not covered by any
        of the foregoing provisions and as are expressly requested by the Issuer
        or the Owner Trustee and are reasonably within the capability of the
        Servicer.

                (ii) Notwithstanding anything in this Agreement or any of the
        Basic Documents to the contrary, the Servicer shall be responsible for
        promptly notifying the Owner Trustee and the Trust Collateral Agent in
        the event that any withholding tax is imposed on the Issuer's payments
        (or allocations of income) to an Owner (as defined in the Trust
        Agreement) as contemplated this Agreement. Any such notice shall be in
        writing and specify the amount of any withholding tax required to be
        withheld by the Owner Trustee or the Trust Collateral Agent pursuant to
        such provision. 

                (iii) Notwithstanding anything in this Agreement or the Basic
        Documents to the contrary, the Servicer shall be responsible for
        performance of the duties of the Issuer set forth in Section 5.1(a),
        (b), (c) and (d) of the Trust Agreement with respect to, among other
        things, accounting and reports to Owners (as defined in the Trust
        Agreement); provided, however, that once prepared by the Servicer the
        Owner Trustee shall retain responsibility for the distribution of the
        Schedule K-1s necessary to enable the Certificateholder to prepare its
        federal and state income tax returns. 

                (iv) The Servicer shall perform the duties of the Servicer
        specified in Section 9.2 of the Trust Agreement required to be performed
        in connection with the resignation or removal of the Owner Trustee, and
        any other duties expressly required to be performed by the Servicer
        under this Agreement or any of the Basic Documents. 

                (v) In carrying out the foregoing duties or any of its other
        obligations under this Agreement, the Servicer may enter into
        transactions with or otherwise deal with any of its Affiliates;
        provided, however, that the terms of any such transactions or dealings
        shall be in accordance with any directions received from the Issuer and
        shall be, in the Servicer's opinion, no less favorable to the Issuer in
        any material respect. 

        (c) Tax Matters. The Servicer shall prepare and file, on behalf of the
Seller, all tax returns, tax elections, financial statements and such annual or
other reports attributable to the activities engaged in by the Issuer as are
necessary for preparation of tax reports, including without limitation forms
1099. All tax returns will be signed by the Seller.

        (d) Non-Ministerial Matters. With respect to matters that in the
reasonable judgment of the Servicer are non-ministerial, the Servicer shall not
take any action pursuant to this Article unless within a reasonable time before
the taking of such action, the Servicer shall have notified the Owner Trustee
and the Trustee of the proposed action and the Owner Trustee and, with respect
to items (A), (B), (C) and (D) below, the Trustee shall not have withheld
consent or provided an alternative direction. For the purpose of the preceding
sentence, "non-ministerial matters" shall include: 

                (A) the amendment of or any supplement to the Indenture;

                                       69
<PAGE>
 
                (B) the initiation of any claim or lawsuit by the Issuer and the
        compromise of any action, claim or lawsuit brought by or against the
        Issuer (other than in connection with the collection of the
        Receivables);

                            Miscellaneous Provisions

        SECTION 12.1. Amendment.

        (a) This Agreement may be amended from time to time by the parties
hereto, with the consent of the Trustee (which consent may not be unreasonably
withheld), with the prior written consent of the Insurer (so long as no Insurer
Default has occurred and is continuing) but without the consent of any of the
Noteholders, to cure any ambiguity, to correct or supplement any provisions in
this Agreement, to comply with any changes in the Code, or to make any other
provisions with respect to matters or questions arising under this Agreement
which shall not be inconsistent with the provisions of this Agreement or the
Insurance Agreement; provided, however, that such action shall not, as evidenced
by an Opinion of Counsel delivered to Owner 

                                       70
<PAGE>
 
Trustee and the Trustee, adversely affect in any material respect the interests
of any Noteholder; provided further that if an Insurer Default has occurred and
is continuing, such action shall not materially adversely affect the interests
of the Insurer.

        This Agreement may also be amended from time to time by the parties
hereto, with the consent of the Insurer, the consent of the Trustee, the consent
of the Holders of Notes evidencing not less than a majority of the outstanding
principal amount of the Notes for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement or
of modifying in any manner the rights of the Noteholders; provided, however,
that no such amendment shall (a) increase or reduce in any manner the amount of,
or accelerate or delay the timing of, collections of payments on Receivables or
distributions that shall be required to be made for the benefit of the
Noteholders or (b) reduce the aforesaid percentage of the outstanding principal
amount of the Notes, the Holders of which are required to consent to any such
amendment, without the consent of the Holders of all the outstanding Notes of
each class affected thereby; provided further, that if an Insurer Default has
not occurred and is continuing, such action shall not materially adversely
affect the interest of the Insurer.

        Promptly after the execution of any such amendment or consent, the Trust
Collateral Agent shall furnish written notification of the substance of such
amendment or consent to each Noteholder and the Rating Agencies.

        It shall not be necessary for the consent of Noteholders pursuant to
this Section to approve the particular form of any proposed amendment or
consent, but it shall be sufficient if such consent shall approve the substance
thereof. The manner of obtaining such consents (and any other consents of
Noteholders provided for in this Agreement) and of evidencing the authorization
of any action by Noteholders shall be subject to such reasonable requirements as
the Trustee or the Owner Trustee, as applicable, may prescribe.

        Prior to the execution of any amendment to this Agreement, the Owner
Trustee and the Trustee, Trust Collateral Agent, Collateral Agent and Backup
Servicer shall be entitled to receive and conclusively rely upon an Opinion of
Counsel stating that the execution of such amendment is authorized or permitted
by this Agreement and the Opinion of Counsel referred to in Section 12.2(h)(1)
has been delivered. The Owner Trustee, the Trust Collateral Agent, the Backup
Servicer and the Trustee may, but shall not be obligated to, enter into any such
amendment which affects the Issuer's, the Owner Trustee's, the Trust Collateral
Agent's, the Backup Servicer's or the Trustee's, as applicable, own rights,
duties or immunities under this Agreement or otherwise.

uses of funds on deposit in the Spread Account may be amended in any respect by
the Seller, the Servicer, the Insurer and the Collateral Agent (the consent of
which shall not be withheld or delayed with respect to any amendment that does
not adversely affect the Collateral Agent) without the consent of, or notice to,
the Noteholders.

        (a) The Seller shall execute and file such financing statements and
cause to be executed and filed such continuation statements, all in such manner
and in such places as may be required by law fully to preserve, maintain and
protect the interest of the Issuer and the interests of the Trust Collateral
Agent in the Receivables and in the proceeds thereof. The Seller shall deliver
(or cause to be delivered) to the Insurer, the Owner Trustee and the Trust
Collateral Agent file-stamped copies of, or filing receipts for, any document
filed as provided above, as soon as available following such filing.

        (b) Neither the Seller nor the Servicer shall change its name, identity
or corporate structure in any manner that would, could or might make any
financing statement or continuation statement filed in accordance with paragraph

it shall have given the Insurer, the Owner Trustee, the Trust Collateral Agent
and the Trustee at least five days' prior written notice thereof and shall have
promptly filed appropriate amendments to all previously filed financing
statements or continuation statements. Promptly upon such filing, the Seller or
the Servicer, as the case may be, shall deliver an Opinion of Counsel in form
and substance reasonably satisfactory to the Insurer, stating either (A) all
financing statements and continuation statements have been executed and filed
that are necessary fully to preserve and protect the interest of the Trust and
the Trust Collateral Agent in the Receivables, and reciting the details of such
filings or referring to prior Opinions of Counsel in which such details are
given, or (B) no such action shall be necessary to preserve and protect such
interest. 

        (c) Each of the Seller and the Servicer shall have an obligation to give
the Insurer, the Owner Trustee, the Trust Collateral Agent and the Trustee at
least 60 days' prior written notice of any relocation of its principal executive
office if, as a result of such relocation, the applicable provisions of the UCC
would require the filing of any amendment of any previously filed financing or
continuation statement or of any new financing statement and shall promptly file
any such amendment. The Servicer shall at all times maintain each office from
which it shall service Receivables, and its principal executive office, within
the United States of America. 

        (d) The Servicer shall maintain accounts and records as to each
Receivable accurately and in sufficient detail to permit (i) the reader thereof
to know at any time the status of such Receivable, including payments and
recoveries made and payments owing (and the nature of each) and (ii)
reconciliation between payments or recoveries on (or with respect to) each
Receivable and the amounts from time to time deposited in the Collection Account
in respect of such Receivable. 

        (e) The Servicer shall maintain its computer systems so that, from and
after the time of sale under this Agreement of the Receivables to the Issuer,
the Servicer's master computer records (including any backup archives) that
refer to a Receivable shall indicate clearly the interest of the Trust in such
Receivable and that such Receivable is owned by the Trust. Indication of the
Trust's interest in a Receivable shall be deleted from or modified on the
Servicer's computer systems when, and only when, the related Receivable shall
have been paid in full or repurchased. 

                                       72

        (f) If at any time the Seller or the Servicer shall propose to sell,
grant a security interest in or otherwise transfer any interest in automotive
receivables to any prospective purchaser, lender or other transferee, the
Servicer shall give to such prospective purchaser, lender or other transferee
computer tapes, records or printouts (including any restored from backup
archives) that, if they shall refer in any manner whatsoever to any Receivable,
shall indicate clearly that such Receivable has been sold and is owned by the
Trust. 

        (g) Upon request, the Servicer shall furnish to the Insurer, the Owner
Trustee or to the Trustee, within five Business Days, a list of all Receivables
(by contract number and name of Obligor) then held as part of the Trust,
together with a reconciliation of such list to the Schedule of Receivables and
to each of the Servicer's Certificates furnished before such request indicating
removal of Receivables from the Trust. 

        (h) The Servicer shall deliver to the Insurer, the Owner Trustee and the
Trustee:

                      (1) promptly after the execution and delivery of the
        Agreement and, if required pursuant to Section 12.1, of each amendment,
        an Opinion of Counsel stating that, in the opinion of such Counsel, in
        form and substance reasonably satisfactory to the Insurer, either (A)
        all financing statements and continuation statements have been executed
        and filed that are necessary fully to preserve and protect the interest
        of the Trust and the Trustee in the Receivables, and reciting the
        details of such filings or referring to prior Opinions of Counsel in
        which such details are given, or (B) no such action shall be necessary
        to preserve and protect such interest; and

                      (2) within 90 days after the beginning of each calendar
        year beginning with the first calendar year beginning more than three
        months after the Cutoff Date, an Opinion of Counsel, dated as of a date

        the interest of the Trust and the Trustee in the Receivables, and
        reciting the details of such filings or referring to prior Opinions of
        Counsel in which such details are given, or (B) no such action shall be
        necessary to preserve and protect such interest.

        Each Opinion of Counsel referred to in clause (1) or (2) above shall
specify any action necessary (as of the date of such opinion) to be taken in the
following year to preserve and protect such interest.

Consumer Credit Code and other consumer credit laws and equal credit opportunity
and disclosure laws) in respect of the Receivables and the Financed Vehicles,
have been complied with in all material respects, and each Receivable and the
sale of the Financed Vehicle evidenced by each Receivable complied at the time
it was originated or made and now complies in all material respects with all
applicable legal requirements.

        4. Origination. Each Receivable was originated in the United States.

        5. Binding Obligation. Each Receivable represents the genuine, legal,
valid and binding payment obligation of the Obligor thereon, enforceable by the
holder thereof in accordance with its terms, except (A) as enforceability may be
limited by bankruptcy, insolvency, reorganization or similar laws affecting the
enforcement of creditors' rights generally and by equitable limitations on the
availability of specific remedies, regardless of whether such enforceability is
considered in a proceeding in equity or at law and (B) as such Receivable may be
modified by the application after the Cutoff Date of the Soldiers' and Sailors'
Civil Relief Act of 1940, as amended; and all parties to each Receivable had
full legal capacity to execute and deliver such 

                                       1
<PAGE>
 
Receivable and all other documents related thereto and to grant the security
interest purported to be granted thereby.

        6. No Government Obligor. No Obligor is the United States of America or
any State or any agency, department, subdivision or instrumentality thereof.

        7. Obligor Bankruptcy. At the related Cutoff Date no Obligor had been
identified on the records of AmeriCredit as being the subject of a current
bankruptcy proceeding.

        8. Schedule of Receivables. The information set forth in the Schedule of
Receivables has been produced from the Electronic Ledger and was true and
correct in all material respects as of the close of business on the related
Cutoff Date.

        9. Marking Records. By the Closing Date or Subsequent Transfer Date, as
applicable, the Seller will have caused the portions of the Electronic Ledger
relating to the Receivables to be clearly and unambiguously marked to show that
the Receivables have been sold to the Seller by the Servicer and resold by the
Seller to the Trust in accordance with the terms of the Sale and Servicing
Agreement.

        10. Computer Tape. The Computer Tape made available by the Seller to the
Trust on the Closing Date or Subsequent Transfer Date, as applicable, was
complete and accurate as of the related Cutoff Date and includes a description
of the same Receivables that are described in the Schedule of Receivables.

        11. Adverse Selection. No selection procedures adverse to the
Noteholders or the Insurer were utilized in selecting the Receivables from those
receivables owned by the Seller which met the selection criteria contained in
the Sale and Servicing Agreement.

        12. Chattel Paper. The Receivables constitute chattel paper within the
meaning of the UCC as in effect in the States of Texas and New York.

        13. One Original. There is only one original executed copy of each
Receivable.

        14. Receivable Files Complete. There exists a Receivable File pertaining
to each Receivable and such Receivable File contains (a) a fully executed
original of the Receivable, (b) the original executed credit application, or a
copy thereof and (c) the original Lien Certificate or application therefor. Each
of such documents which is required to be signed by the Obligor has been signed
by the Obligor in the appropriate spaces. All blanks on any form have been
properly filled in and each form has otherwise been correctly prepared. The
complete Receivable File for each Receivable currently is in the possession of
the Custodian.

        15. Receivables in Force. No Receivable has been satisfied, subordinated
or rescinded, and the Financed Vehicle securing each such Receivable has not
been released from the lien of the related Receivable in whole or in part. No
terms of any Receivable have been waived, altered or modified in any respect
since its origination, except by instruments or documents identified in the
Receivable File. No Receivable has been modified as a result of application of
the Soldiers' and Sailors' Civil Relief Act of 1940, as amended.

        16. Lawful Assignment. No Receivable was originated in, or is subject to
the laws of, any jurisdiction the laws of which would make unlawful, void or
voidable the sale, transfer and assignment of such Receivable under this
Agreement or pursuant to transfers of the Securities.

        17. Good Title. Immediately prior to the conveyance of the Receivables
to the Trust pursuant to this Agreement or Subsequent Transfer Agreement, as
applicable, the Seller was the sole owner thereof and had good and indefeasible
title thereto, free of any Lien and, upon execution and delivery of this
Agreement by the Seller, the Trust shall have good and indefeasible title to and
will be the sole owner of such Receivables, free of any Lien. No Dealer has a
participation in, or other right to receive, proceeds of any Receivable. The
Seller has not taken any action to convey any right to any Person that would
result in such Person having a right to payments received under the related
Insurance Policies or the related Dealer Agreements or Dealer Assignments or to
payments due under such Receivables.

        18. Security Interest in Financed Vehicle. Each Receivable created or
shall create a valid, binding and enforceable first priority security interest
in favor of the Seller in the Financed Vehicle. The Lien Certificate and
original certificate of title for each Financed Vehicle show, or if a new or
replacement Lien Certificate is being applied for with respect to such Financed
Vehicle the Lien Certificate will be received within 180 days of the Closing
Date or Subsequent Transfer Date, as applicable, and will show the Seller named
as the original secured party under each Receivable as the holder of a first
priority security interest in such Financed Vehicle. With respect to each
Receivable for which the Lien Certificate has not yet been returned from the
Registrar of Titles, the Seller has received written evidence from the related
Dealer that such Lien Certificate showing the Seller as first lienholder has
been applied for and the Seller's security interest has been validly assigned by
the Seller to the Trust pursuant to this Agreement. Immediately after the sale,
transfer and assignment thereof by the Seller to the Trust, each Receivable will
be secured by an enforceable and perfected first priority security interest in
the Financed Vehicle in favor of the Trustee as secured party, which security
interest is prior to all other Liens upon and security interests in such
Financed Vehicle which now exist or may hereafter arise or be created (except,
as to priority, for any lien for taxes, labor or materials affecting a Financed
Vehicle). As of the related Cutoff Date there were no Liens or claims for taxes,
work, labor or materials affecting a Financed Vehicle which are or may be Liens
prior or equal to the Liens of the related Receivable.

        19. All Filings Made. All filings (including, without limitation, UCC
filings) required to be made by any Person and actions required to be taken or
performed by any Person in any jurisdiction to give the Trust a first priority
perfected lien on, or ownership interest in, the Receivables and the proceeds
thereof and the Other Conveyed Property have been made, taken or performed.

        20. No Impairment. The Seller has not done anything to convey any right
to any Person that would result in such Person having a right to payments due
under the Receivable or otherwise to impair the rights of the Trust, the
Insurer, the Trustee, the Trust Collateral Agent and the Noteholders in any
Receivable or the proceeds thereof.

                                       3
<PAGE>
 
        21. Receivable Not Assumable. No Receivable is assumable by another
Person in a manner which would release the Obligor thereof from such Obligor's
obligations to AmeriCredit with respect to such Receivable.

        22. No Defenses. No Receivable is subject to any right of rescission,
setoff, counterclaim or defense and no such right has been asserted or
threatened with respect to any Receivable.

        23. No Default. There has been no default, breach, violation or event
permitting acceleration under the terms of any Receivable (other than payment
delinquencies of not more than 30 days), and no condition exists or event has
occurred and is continuing that with notice, the lapse of time or both would
constitute a default, breach, violation or event permitting acceleration under
the terms of any Receivable, and there has been no waiver of any of the
foregoing. As of the related Cutoff Date no Financed Vehicle had been
repossessed.

        24. Insurance. At the time of a purchase of a Receivable by AmeriCredit
from a Dealer, each Financed Vehicle is required to be covered by a
comprehensive and collision insurance policy (i) in an amount at least equal to
the lesser of (a) its maximum insurable value or (b) the principal amount due
from the Obligor under the related Receivable, (ii) naming AmeriCredit as loss
payee and (iii) insuring against loss and damage due to fire, theft,
transportation, collision and other risks generally covered by comprehensive and
collision coverage. Each Receivable requires the Obligor to maintain physical
loss and damage insurance, naming AmeriCredit and its successors and assigns as
additional insured parties, and each Receivable permits the holder thereof to
obtain physical loss and damage insurance at the expense of the Obligor if the
Obligor fails to do so. No Financed Vehicle is insured under a policy of
Force-Placed Insurance on the related Cutoff Date.

        25. Past Due. At the related Cutoff Date no Receivable was more than 30
days past due.

        26. Remaining Principal Balance. At the related Cutoff Date the
Principal Balance of each Receivable set forth in the Schedule of Receivables is
true and accurate in all material respects.

        27. Certain Characteristics of Initial Receivables. (A) Each Initial
Receivable had a remaining maturity, as of the Initial Cutoff Date, of not more
than 72 months; (B) each Receivable had an original maturity of not more than 72
months; (C) each Initial Receivable had a remaining Principal Balance as of the
Initial Cutoff Date of at least $250 and not more than $30,000; (D) each Initial
Receivable has an Annual Percentage Rate of at least 12.50% and not more than
33.00%; (E) no Initial Receivable was more than 30 days past due as of the
Initial Cutoff Date and (F) no funds have been advanced by AmeriCredit, any
Dealer, or anyone acting on behalf of any of them in order to cause any Initial
Receivable to qualify under clause (E) above.

                        SERVICING POLICIES AND PROCEDURES

                       Note: Applicable Time Periods Will Vary by State

COMPLIANCE WITH STATE COLLECTION LAWS IS REQUIRED OF ALL AMERICREDIT COLLECTION
PERSONNEL. ADDITIONALLY, AMERICREDIT HAS CHOSEN TO FOLLOW THE GUIDELINES OF THE
FEDERAL FAIR DEBT COLLECTION PRACTICES ACT (FDCPA).

The Collection Process

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

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

B.      Accounts are then segregated into two groups, those less than 30 days
        delinquent and those over 30 days delinquent.

C.      Accounts less than 30 days delinquent are further segregated into
        accounts that have good residential and business phone numbers and those
        that do not.

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

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

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

G.      At the time the account reaches 31 days delinquent, it is assigned to a
        mid-range collector. At this time the collector identifies the necessity
        of any default notification required by state law.

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

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

Repossessions

                                       1
<PAGE>
 
If repossession of the collateral occurs, whether voluntary or involuntary, the
following steps are taken:

A.       Notification of repossession to proper authorities when necessary.

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

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

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

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

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

Use of Due Date Changes

Due dates may be changed subject to the following conditions:

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

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

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

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

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

Use of Payment Deferments

A payment deferral is offered to customers who have encountered temporary
financial difficulties.

A.       Minimum of six payments have been made on the account.

B.      The account will be brought current with the deferment, but not paid
        ahead.

C.      A deferment fee is collected on all transactions.

D.      Only one deferment transaction can be performed in a twelve month
        period.

                                       2
<PAGE>
 
E.      No more than two payments may be deferred in a twelve month period, and
        no more than eight total payments may be deferred over the life of the
        loan.

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

Charge-Offs

A.      When a Post Repossession Notice is generated on an account, the account
        may be partially charged-off on the date that the notice legally
        expires. The partial charge-off calculation is based on the expected
        residual value of the vehicle at time of sale. Adjustments to the
        account are made once final liquidation of the vehicle occurs.

B.      It is AmeriCredit's policy that any account that is not successfully
        recovered by 180 days delinquent is submitted to an Officer for approval
        and charge-off.

C.      It is AmeriCredit's policy to carry all Chapter 13 bankruptcy accounts
        until confirmation of the plan. Once the plan is approved, a partial
        charge-off is taken for the unsecured portion of the account. On fully
        reaffirmed Chapter 7 bankruptcy accounts, the accounts are deferred
        current at the time of discharge.

Deficiency Collections

A.      Contact is made with the customer in an attempt to establish acceptable
        payment arrangements or settlements on the account.

B.      If the customer is unwilling to do so, AmeriCredit may invoke any legal
        collection remedy that the state allows, i.e., judgements, garnishments,
        etc.

        FINANCIAL SECURITY ASSURANCE INC. ("Financial Security"), for
consideration received, hereby UNCONDITIONALLY AND IRREVOCABLY GUARANTEES to
each Holder, subject only to the terms of this Policy (which includes each
endorsement hereto), the full and complete payment by the Obligor of Scheduled
Payments of principal of, and interest on, the Obligations.

        For the further protection of each Holder, Financial Security
irrevocably and unconditionally guarantees:
        (a) payment of the amount of any distribution of principal of, or
   interest on, the Obligations made during the Term Of This Policy to such
   Holder that is subsequently avoided in whole or in part as a preference
   payment under applicable law (such payment to be made by Financial Security
   in accordance with Endorsement No. 1 hereto).

        (b) payment of any amount required to be paid under this Policy by
   Financial Security following Financial Security's receipt of notice as
   described in Endorsement No. 1 hereto.

        Financial Security shall be subrogated to the rights of each Holder to
receive payments under the Obligations to the extent of any payment by Financial
Security hereunder.

        Except to the extent expressly modified by an endorsement hereto, the
following terms shall have the meanings specified for all purposes of this
Policy.  "Holder" means the registered owner of any Obligation as indicated on
the registration books maintained by or on behalf of the Obligor for such
purpose or, if the Obligation is in bearer form, the holder of the Obligation.
"Scheduled Payments" means payments which are scheduled to be made during the
Term Of This Policy in accordance with the original terms of the Obligations

Obligations thereafter; payments which become due on an accelerated basis as a
result of (a) a default by the Obligor, (b) an election by the Obligor to pay
principal on an accelerated basis or (c) any other cause, shall not constitute
"Scheduled Payments" unless Financial Security shall elect, in its sole
discretion, to pay such principal due upon such acceleration together with any
accrued interest to the date of acceleration.  "Term Of This Policy" shall have
the meaning set forth in Endorsement No. 1 hereto.

        This Policy sets forth in full the undertaking of Financial Security,
and shall not be modified, altered or affected by any other agreement or
instrument, including any modification or amendment thereto, or by the merger,
consolidation or dissolution of the Obligor.  Except to the extent expressly
modified by an endorsement hereto, the premiums paid in respect of this Policy
are nonrefundable for any reason whatsoever, including payment, or provision
being made for payment, of the Obligations prior to maturity.  This Policy may
not be canceled or revoked during the Term Of This Policy.  THIS POLICY IS NOT
COVERED BY THE PROPERTY/CASUALTY INSURANCE SECURITY FUND SPECIFIED IN ARTICLE 76

Security may at any time during the continuation of any proceeding by or against

Proceeding, including without limitation, (A) all matters relating to any claim
in connection with an Insolvency Proceeding seeking the avoidance as a
preferential transfer of any payment made with respect to the Obligations (a

any Preference Claim at the expense of Financial Security but subject to
reimbursement as provided in the Insurance Agreement and (C) the posting of any
surety, supersedeas or performance bond pending any such appeal.  In addition,
the Trust Collateral Agent hereby agrees that Financial Security shall be
subrogated to, and the Trust Collateral Agent on its behalf and on behalf of
each Holder, hereby delegates and assigns, to the fullest extent permitted by
law, the rights of the Trust Collateral Agent and each Holder in the conduct of
any Insolvency Proceeding, including, without limitation, all rights of any
party to an adversary proceeding or action with respect to any court order
issued in connection with any such Insolvency Proceeding.

          (vii)  Payment should be made by wire transfer directed to [SPECIFY
ACCOUNT].

     Unless the context otherwise requires, capitalized terms used in this
Notice of Claim and Certificate and not defined herein shall have the meanings

of the Subsequent Receivables and the Subsequent Other Conveyed Property from
Sellers to Purchaser, conveying good title thereto free and clear of any liens,
and the beneficial interest in and title to the Subsequent Receivables and the

bankruptcy or similar law.

     pay or cause to be paid to or upon the order of Sellers an amount equal to
     the book value of the Subsequent Receivables on the books and records of
     the Sellers, by wire transfer of immediately available funds.

                                  ARTICLE III.

                                  REPURCHASES

        SECTION 5.1 Repurchase of Receivables Upon Breach of Warranty. Upon the
                    -------------------------------------------------
occurrence of a Repurchase Event, AFS shall, unless the breach which is the
subject of such Repurchase Event shall have been cured in all material respects,
repurchase the Receivable relating thereto from the Issuer and, simultaneously
with the repurchase of the Receivable, AFS shall deposit the Purchase Amount in
full, without deduction or offset, to the Collection Account, pursuant to
Section 3.2 of the Sale and Servicing Agreement. It is understood and agreed
that, except as set forth in Section 6.1 hereof, the obligation of AFS to
repurchase any Receivable, as to which a breach occurred and is continuing,
shall, if such obligation is fulfilled, constitute the sole remedy against AFS
for such breach available to Purchaser, the Issuer, the Insurer, the Backup
Servicer, the Noteholders, the Certificateholder, the Trust Collateral Agent on
behalf of the Noteholders or the Owner Trustee on behalf of the
Certificateholder. The provisions of this 

                                       13
<PAGE>
 
Section 5.1 are intended to grant the Issuer and the Trust Collateral Agent a
direct right against AFS to demand performance hereunder, and in connection
therewith, AFS waives any requirement of prior demand against Purchaser with
respect to such repurchase obligation. Any such repurchase shall take place in
the manner specified in Section 3.2 of the Sale and Servicing Agreement.
Notwithstanding any other provision of this Agreement or the Sale and Servicing
Agreement to the contrary, the obligation of AFS under this Section shall not
terminate upon a termination of AFS as Servicer under the Sale and Servicing
Agreement and shall be performed in accordance with the terms hereof
notwithstanding the failure of the Servicer or Purchaser to perform any of their
respective obligations with respect to such Receivable under the Sale and
Servicing Agreement.

          In addition to the foregoing and notwithstanding whether the related
Receivable shall have been purchased by AFS, AFS shall indemnify the Issuer, the
Trust Collateral Agent, the Trustee, the Backup Servicer, the Owner Trustee, the
Insurer, the Noteholders and the Certificateholder against all costs, expenses,
losses, damages, claims and liabilities, including reasonable fees and expenses
of counsel, which may be asserted against or incurred by any of them as a result
of third party claims arising out of the events or facts giving rise to such
Repurchase Events.

        SECTION 5.2 Reassignment of Purchased Receivables. Upon deposit in the
                    -------------------------------------
Collection Account of the Purchase Amount of any Receivable repurchased by AFS
under Section 5.1 hereof, Purchaser and the Issuer shall take such steps as may
be reasonably requested by AFS in order to assign to AFS all of Purchaser's and
the Issuer's right, title and interest in and to such Receivable and all
security and documents and all Other Conveyed Property conveyed to Purchaser and
the Issuer directly relating thereto, without recourse, representation or
warranty, except as to the absence of liens, charges or encumbrances created by
or arising as a result of actions of Purchaser or the Issuer. Such assignment
shall be a sale and assignment outright, and not for security. If, following the
reassignment of a Purchased Receivable, in any enforcement suit or legal
proceeding, it is held that AFS may not enforce any such Receivable on the
ground that it shall not be a real party in interest or a holder entitled to
enforce the Receivable, Purchaser and the Issuer shall, at the expense of AFS,
take such steps as AFS deems reasonably necessary to enforce the Receivable,
including bringing suit in Purchaser's or in the Issuer's name.

        SECTION 5.3 Waivers. No failure or delay on the part of Purchaser, or
                    -------
the Issuer as assignee of Purchaser, 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 or future
exercise thereof or the exercise of any other power, right or remedy.

                                  ARTICLE VI.


                                 MISCELLANEOUS

        SECTION 6.1 Liability of Sellers. Sellers shall be liable in accordance
                    --------------------
herewith only to the extent of the obligations in this Agreement specifically
undertaken by Sellers and the representations and warranties of Sellers.

        SECTION 6.2 Merger or Consolidation of Sellers or Purchaser. Any
                    -----------------------------------------------
corporation or other entity (i) into which Sellers or Purchaser may be merged or
consolidated, (ii) resulting from any merger or consolidation to which Sellers
or Purchaser is a party or (iii) succeeding to the business of Sellers or
Purchaser, in the case of Purchaser, which corporation has a certificate of
incorporation containing provisions relating to limitations on business and
other matters substantively identical to those contained in Purchaser's
certificate of incorporation, provided that in any of the foregoing cases such
corporation shall execute an agreement of assumption to perform every obligation
of Sellers or Purchaser, as the case may be, under this Agreement and, whether
or not such assumption agreement is executed, shall be the successor to Sellers
or Purchaser, as the case may be, hereunder (without relieving Sellers or
Purchaser of their responsibilities hereunder, if it survives such merger or
consolidation) without the execution or filing of any document or any further
action by any of the parties to this Agreement.  Notwithstanding the foregoing,
so long as an Insurer Default shall not have occurred and be continuing,
Purchaser shall not merge or consolidate with any other Person or permit any
other Person to become the successor to Purchaser's business without the prior
written consent of the Insurer.  Sellers or Purchaser shall promptly inform the
other party, the Issuer, the Trust Collateral Agent, the Owner Trustee and, so
long as an Insurer Default shall not have occurred and be continuing, the
Insurer of such merger, consolidation or purchase and assumption.
Notwithstanding the foregoing, as a condition to the consummation of the
transactions referred to 

                                       15
<PAGE>
 
in clauses (i), (ii) and (iii) above, (x) immediately after giving effect to
such transaction, no representation or warranty made pursuant to Sections 3.1,
3.2 and 3.3 of this Agreement shall have been breached (for purposes hereof,
such representations and warranties shall speak as of the date of the
consummation of such transaction) and no event that, after notice or lapse of
time, or both, would become an event of default under the Insurance Agreement,
shall have occurred and be continuing, (y) Sellers or Purchaser, as applicable,
shall have delivered written notice of such consolidation, merger or purchase
and assumption to the Rating Agencies prior to the consummation of such
transaction and shall have delivered to the Issuer and the Trust Collateral
Agent 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 6.2 and that all conditions precedent, if any, provided for in this
Agreement relating to such transaction have been complied with, and (z) Sellers
or Purchaser, as applicable, shall have delivered to the Issuer and the Trust
Collateral Agent 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 Issuer and the Trust Collateral Agent in the Receivables and
reciting the details of the filings or (B) no such action shall be necessary to
preserve and protect such interest.

        SECTION 6.3 Limitation on Liability of Sellers and Others. Sellers and
                    ---------------------------------------------
any director, officer, employee or agent may rely in good faith on the advice of
counsel or on any document of any kind prima facie properly executed and
submitted by any Person respecting any matters arising under this Agreement.
Sellers shall not be under any obligation to appear in, prosecute or defend any
legal action that is not incidental to its obligations under this Agreement or
its Related Documents and that in its opinion may involve it in any expense or
liability.

        SECTION 6.4 Sellers May Own Notes or the Certificate. Subject to the
                    ----------------------------------------
provisions of the Sale and Servicing Agreement, Sellers and any Affiliate of
Sellers may in their individual or any other capacity become the owner or
pledgee of Notes or the Certificate with the same rights as they would have if
they were not Sellers or an Affiliate thereof.

        SECTION 5.5  Amendment.
                     --------- 

          (a) This Agreement may be amended by Sellers and Purchaser with the
     prior written consent of the Insurer (so long as an Insurer Default shall
     not have occurred and be continuing) but without the consent of the Trust
     Collateral Agent, the Owner Trustee, the Certificateholder or any of the
     Noteholders (i) to cure any ambiguity or (ii) to correct any provisions in
     this Agreement; provided, however, that such action shall not, as evidenced
     by an Opinion of Counsel delivered to the Issuer, the Owner Trustee and the
     Trust Collateral Agent, adversely affect in any material respect the
     interests of any Certificateholder or Noteholder.

          (b) This Agreement may also be amended from time to time by Sellers
     and Purchaser, with the prior written consent of the Insurer (so long as an
     Insurer Default shall not have occurred and be continuing) and with the
     consent of the Trust Collateral Agent and, if required, the
     Certificateholder and the Noteholders, in accordance with the Sale and
     Servicing Agreement, for the purpose of adding any provisions to or
     changing in any manner or eliminating any of the provisions of this
     Agreement, or of modifying in 

                                       16
<PAGE>
 
     any manner the rights of the Certificateholder or Noteholders; provided,
                                                                    --------
     however, the Sellers provide the Trust Collateral Agent with an Opinion of
     -------  
     Counsel, (which may be provided by the Sellers' Internal Counsel) that no
     such amendment shall increase or reduce in any manner the amount of, or
     accelerate or delay the timing of, collections of payments on Receivables
     or distributions that shall be required to be made on any Note or
     Certificate.

          (c) Prior to the execution of any such amendment or consent, Sellers
     shall have furnished written notification of the substance of such
     amendment or consent to each Rating Agency.

          (d) It shall not be necessary for the consent of Certificateholder or
     Noteholders pursuant to this Section to approve the particular form of any
     proposed amendment or consent, but it shall be sufficient if such consent
     shall approve the substance thereof.  The manner of obtaining such consents
     and of evidencing the authorization of the execution thereof by
     Certificateholder or Noteholders shall be subject to such reasonable
     requirements as the Trust Collateral Agent may prescribe, including the
     establishment of record dates.  The consent of a Holder of a Certificate or
     a Note given pursuant to this Section or pursuant to any other provision of
     this Agreement shall be conclusive and binding on such Holder and on all
     future Holders of such Certificate or Note and of any Certificate or Note
     issued upon the transfer thereof or in exchange thereof or in lieu thereof
     whether or not notation of such consent is made upon the Certificate or
     Note.

interest in all of Sellers' right, title and interest in and to the Receivables

shall constitute but one and the same instrument.

Property to the Issuer. Sellers acknowledge that Purchaser intends, pursuant to
- ----------------------
the Sale and Servicing Agreement, to convey the Receivables and the Other

Trustee, the Trust Collateral Agent, the Noteholders and the Certificateholder.

        11.     Adverse Selection. No selection procedures adverse to the
                -----------------
Noteholders or the Insurer were utilized in selecting the Receivables from those
receivables owned by either AmeriCredit or CP Funding which met the selection
criteria contained in the Sale and Servicing Agreement.

        12.     Chattel Paper. The Receivables constitute chattel paper within
                -------------
the meaning of the UCC as in effect in the States of Texas and New York.

        13.     One Original. There is only one original executed copy of each
                ------------

        14.     Receivable Files Complete. There exists a Receivable File

application therefor. Each of such documents which is required to be signed by
the Obligor has been signed by the Obligor in the appropriate spaces. All blanks
on any form have been properly filled in and each form has otherwise been
correctly prepared. The complete Receivable File for each Receivable currently

        15.     Receivables in Force. No Receivable has been satisfied,
                --------------------
subordinated or rescinded, and the Financed Vehicle securing each such
Receivable has not been released from the lien of the related Receivable in
whole or in part. No terms of any Receivable have been waived, altered or
modified in any respect since its origination, except by instruments or
documents identified in the Receivable File. No Receivable has been modified as
a result of application of

                                       24
<PAGE>
 
the Soldiers' and Sailors' Civil Relief Act of 1940, as amended.

        16.     Lawful Assignment. No Receivable was originated in, or is
                -----------------
subject to the laws of, any jurisdiction the laws of which would make unlawful,
void or voidable the sale, transfer and assignment of such Receivable under this
Agreement or pursuant to transfers of the Notes.

        17.     Good Title. Immediately prior to the conveyance of the
                ----------
Receivables to AFS Funding pursuant to this Agreement or Subsequent Purchase
Agreement, as applicable, either AmeriCredit or CP Funding was the sole owner
thereof and had good and indefeasible title thereto, free of any Lien and, upon
execution and delivery of this Agreement by both AmeriCredit and CP Funding, AFS
Funding shall have good and indefeasible title to and will be the sole owner of
such Receivables, free of any Lien. No Dealer has a participation in, or other
right to receive, proceeds of any Receivable. Neither AmeriCredit nor CP Funding
has taken any action to convey any right to any Person that would result in such
Person having a right to payments received under the related Insurance Policies
or the related Dealer Agreements or Dealer Assignments or to payments due under
such Receivables.

        18.     Security Interest in Financed Vehicle. Each Receivable created
                ------------------------------------- 
or shall create a valid, binding and enforceable first priority security
interest in favor of either AmeriCredit or CP Funding in the Financed Vehicle.
The Lien Certificate and original certificate of title for each Financed Vehicle
show, or if a new or replacement Lien Certificate is being applied for with
respect to such Financed Vehicle the Lien Certificate will be received within
180 days of the Closing Date or Subsequent Transfer Date, as applicable, and
will show AmeriCredit named as the original secured party under each Receivable
as the holder of a first priority security interest in such Financed Vehicle.
With respect to each Receivable for which the Lien Certificate has not yet been
returned from the Registrar of Titles, AmeriCredit has received written evidence
from the related Dealer that such Lien Certificate showing AmeriCredit as first
lienholder has been applied for and AmeriCredit's security interest has been
validly assigned by AmeriCredit either (A) to AFS Funding or (B) to CP Funding
and by CP Funding to AFS Funding pursuant to this Agreement. Immediately after
the sale, transfer and assignment thereof by either AmeriCredit or CP Funding to
AFS Funding, each Receivable will be secured by an enforceable and perfected
first priority security interest in the Financed Vehicle in favor of AFS Funding
as secured party, which security interest is prior to all other Liens upon and
security interests in such Financed Vehicle which now exist or may hereafter
arise or be created (except, as to priority, for any lien for taxes, labor or
materials affecting a Financed Vehicle). As of the related Cutoff Date there
were no Liens or claims for taxes, work, labor or materials affecting a Financed
Vehicle which are or may be Liens prior or equal to the Liens of the related
Receivable.

        19.     All Filings Made. All filings (including, without limitation,
                ----------------
UCC filings) required to be made by any Person and actions required to be taken

proceeds thereof and the Other Conveyed Property have been made, taken or
performed.

        20.     No Impairment. Neither AmeriCredit nor CP Funding have done
                -------------
anything to convey any right to any Person that would result in such Person
having a right to payments due under the 

                                       25
<PAGE>
 
Receivable or otherwise to impair the rights of the Trust, the Insurer, the
Trustee, the Trust Collateral Agent and the Noteholders in any Receivable or the
proceeds thereof.

        21.     Receivable Not Assumable. No Receivable is assumable by another
                ------------------------
Person in a manner which would release the Obligor thereof from such Obligor's
obligations to AmeriCredit with respect to such Receivable.

        22.     No Defenses. No Receivable is subject to any right of
                -----------
rescission, setoff, counterclaim or defense and no such right has been asserted
or threatened with respect to any Receivable.

        23.     No Default. There has been no default, breach, violation or
                ----------
event permitting acceleration under the terms of any Receivable (other than
payment delinquencies of not more than 30 days), and no condition exists or
event has occurred and is continuing that with notice, the lapse of time or both
would constitute a default, breach, violation or event permitting acceleration
under the terms of any Receivable, and there has been no waiver of any of the
foregoing. As of the related Cutoff Date no Financed Vehicle had been
repossessed.

        24.     Insurance. At the time of a purchase of a Receivable by
                ---------   
AmeriCredit from a Dealer, each Financed Vehicle is required to be covered by a
comprehensive and collision insurance policy (i) in an amount at least equal to
the lesser of (a) its maximum insurable value or (b) the principal amount due
from the Obligor under the related Receivable, (ii) naming AmeriCredit as loss
payee and (iii) insuring against loss and damage due to fire, theft,
transportation, collision and other risks generally covered by comprehensive and
collision coverage. Each Receivable requires the Obligor to maintain physical
loss and damage insurance, naming AmeriCredit and its successors and assigns as
additional insured parties, and each Receivable permits the holder thereof to
obtain physical loss and damage insurance at the expense of the Obligor if the
Obligor fails to do so. No Financed Vehicle is insured under a policy of Force-
Placed Insurance on the related Cutoff Date.

        25.     Past Due. At the related Cutoff Date no Receivable was more than
                --------

          (a)  Organization, Etc.  Financial Security is a stock insurance
               -----------------                                          
     company duly organized, validly existing and authorized to transact
     financial guaranty insurance business under the laws of the State of New
     York.

          (b)  Authorization, Etc.  The Policy and the Financial Security
               ------------------                                        
     Agreements have been duly authorized, executed and delivered by Financial
     Security.

          (c)  Validity, Etc.  The Policy and the Financial Security Agreements
               -------------

     the enforcement of remedies, to bankruptcy, insolvency, reorganization,

          (e)  No Conflicts.  Neither the execution or delivery by Financial
               ------------                                                 
     Security of the Policy or the Financial Security Agreements, nor the
     performance by Financial Security of its obligations thereunder, will
     conflict with any provision of the certificate of incorporation or the
     bylaws of Financial Security nor result in a breach of, or constitute a
     default under, any material agreement or other instrument to which
     Financial Security is a party or by which any of its property is bound nor
     violate any judgment, order or decree applicable to Financial Security of
     any governmental or regulatory body, administrative agency, court or
     arbitrator having jurisdiction over Financial Security (except that, in the
     published opinion of the Securities and Exchange Commission, the
     indemnification provisions of this Agreement, insofar as they relate to
     indemnification for liabilities arising under the Securities Act, are
     against public policy as expressed in the Securities Act and are therefore
     unenforceable).

          (f)  Financial Information.  The consolidated balance sheets of
               ---------------------

     consolidated balance sheet of Financial Security as of March 31, 1998, and
     the related statements of income, changes in shareholder equity and cash
     flows for the interim period then ended, which are incorporated by
     reference in the Prospectus, fairly present in all material respects the
     financial condition of Financial Security as of such dates and for such
     periods in accordance with generally accepted accounting principles
     consistently applied (subject as to interim statements to normal year-end
     adjustments) and since the date of the most current interim consolidated
     balance sheet referred to above there has been no change in the financial
     condition of Financial Security which would materially and adversely affect
     its ability to perform its obligations under the Policy.

          (g)  Financial Security Information.  The information in the
               ------------------------------                         
     Prospectus Supplement set forth under the caption "The Insurer" (as revised
     from time to time in accordance with the provisions hereof, the "Financial
                                                                      ---------
     Security Information") is limited and does not purport to provide the scope
     --------------------                                                       
     of disclosure required to be included in a prospectus with respect to a
     registrant in connection with the offer and sale of securities of such
     registrant registered under the Securities Act.  Within such limited scope
     of disclosure, however, as of the date of the Prospectus Supplement and as
     of the date hereof, the Financial Security Information does not contain any
     untrue statement of a material fact, or omit to state a material fact
     necessary to make the statements contained therein, in the light of the
     circumstances under which they were made, not misleading.

          (h)  Additional Information.  Financial Security will furnish to the
               ----------------------                                         
     Underwriters or the Seller, upon request of the Underwriters or the Seller,
     as the case may be, copies of Financial Security's most recent financial
     statements (annual or interim, as the case may be) which fairly present in
     all material respects the financial condition of Financial Security as of
     the dates and for the periods indicated, in accordance with generally
     accepted accounting principles consistently applied except as noted therein
     (subject, as to interim statements, to 

                                       4
<PAGE>
 
     normal year-end adjustments). In addition, if the delivery of an Prospectus
     relating to the Securities is required at any time prior to the expiration
     of nine months after the time of issue of the Prospectus in connection with
     the offering or sale of the Securities, the Seller or the Underwriters will
     notify Financial Security of such requirement to deliver an Prospectus and
     Financial Security will promptly provide the Underwriters and the Seller
     with any revisions to the Financial Security Information that are in the
     judgment of Financial Security necessary to prepare an amended Prospectus
     or a supplement to the Prospectus.

          (i)  Opinion of Counsel.  Financial Security will furnish to the
               ------------------                                         
     Underwriters and the Seller on the closing date for the sale of the
     Securities an opinion of its Assistant General Counsel, to the effect set
     forth in Exhibit A attached hereto, dated such closing date and addressed
     to the Seller and the Underwriters.

          (j)  Consents and Reports of Independent Accountants.  Financial
               -----------------------------------------------            
     Security will furnish to the Underwriters and the Seller, upon request, as
     comfort from its independent accountants in respect of its financial
     condition, (i) at the expense of the Person specified in the Insurance
     Agreement, a copy of the Prospectus, including either a manually signed
     consent or a manually signed report of Financial Security's independent
     accountants and (ii) the quarterly review letter by Financial Security's
     independent accountants in respect of the most recent interim financial
     statements of Financial Security.

Nothing in this Agreement shall be construed as a representation or warranty by
Financial Security concerning the rating of its claims-paying ability by Moody's
Investors Service, Inc. or Standard & Poor's Ratings Services or any other
rating agency (collectively, the "Rating Agencies").  The Rating Agencies, in
                                  ---------------                            
assigning such ratings, take into account facts and assumptions not described in
the Prospectus and the facts and assumptions which are considered by the Rating
Agencies, and the ratings issued thereby, are subject to change over time.

     Section 3.  Representations, Warranties and Agreements of the Underwriters.
                 ---------------------------------------------------------------
Each of the Underwriters represents, warrants and agrees as follows:

          (a)  Compliance With Laws.  Such Underwriter will comply in all
               --------------------                                      
     material respects with all legal requirements in connection with offers and
     sales of the Securities and make such offers and sales in the manner
     provided in the Prospectus.

          (b)  Offering Document.  Such Underwriter will not use, or distribute
               -----------------                                               
     to other broker-dealers for use, any Offering Document in connection with
     the offer and sale of the Securities unless such Offering Document includes
     such information as has been furnished by Financial Security for inclusion
     therein and the information therein concerning Financial Security has been
     approved by Financial Security in writing. Financial Security hereby
     consents to the information in respect of Financial Security included in
     the Prospectus. Each Offering Document will include the following
     statement:

                                       5
<PAGE>
 
          "The Policy is not covered by the property/casualty insurance security
          fund specified in Article 76 of the New York Insurance Law".

     Each Offering Document including financial information with respect to
     Financial Security prepared in accordance with generally accepted
     accounting principles will include the following statement immediately
     preceding such financial information:

          "The New York State Insurance Department recognizes only statutory
          accounting practices for determining and reporting the financial
          condition and results of operations of an insurance company, for
          determining its solvency under the New York Insurance Law, and for
          determining whether its financial condition warrants the payment of a
          dividend to its stockholders.  No consideration is given by the New
          York State Insurance Department to financial statements prepared in
          accordance with generally accepted accounting principles in making
          such determinations."

          (c)  Underwriter Information.  All material provided by the
               -----------------------                               
     Underwriters for inclusion in the Prospectus (as revised from time to time,
     the "Underwriter Information"), insofar as such information relates to the
          -----------------------                                              
     Underwriters, is true and correct in all material respects.  In respect of
     the Prospectus Supplement, the Underwriter Information is limited to the
     information set forth (i) in the sixth and seventh paragraphs of the cover
     page, (ii) the first full paragraph of page S-3, and (iii) under the

     Section 4.  Indemnification.
                 --------------- 

          (a)  Financial Security agrees, upon the terms and subject to the
     conditions provided herein, to indemnify, defend and hold harmless each
     Seller Party and each Underwriter Party against (i) any and all Losses
     incurred by them with respect to the offer and sale of the Securities and
     resulting from Financial Security's breach of any of its representations,
     warranties or agreements set forth in Section 2 hereof and (ii) any and all
     Losses to which any Seller Party or Underwriter Party may become subject,
     under the Securities Act or otherwise, insofar as such Losses arise out of
     or result from an untrue statement of a material fact contained in any
     Offering Document or the omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading, in each case to the extent, but only to the extent, that such
     untrue statement or omission was made in the Financial Security Information
     included therein in accordance with the provisions hereof.

          (b)  Each of the Underwriters, agrees, upon the terms and subject to
     the conditions provided herein, to indemnify, defend and hold harmless each
     Financial Security Party and 

                                       6
<PAGE>
 
     each Seller Party against (i) any and all Losses incurred by them with
     respect to the offer and sale of the Securities and resulting from the
     Underwriters' breach of any of its representations, warranties or
     agreements set forth in Section 3 hereof and (ii) any and all Losses to
     which any Financial Security Party or Seller Party may become subject,
     under the Securities Act or otherwise, insofar as such Losses arise out of
     or result from an untrue statement of a material fact contained in any
     Offering Document or the omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading, in each case to the extent, but only to the extent, that such
     untrue statement or omission was made in the Underwriter Information
     included therein.

          (c)  Upon the incurrence of any Losses for which a party is entitled
     to indemnification hereunder, the Indemnifying Party shall reimburse the
     Indemnified Party promptly upon establishment by the Indemnified Party to
     the Indemnifying Party of the Losses incurred.

     Section 5.  Indemnification Procedures.  Except as provided below in
                 --------------------------                              
Section 6 with respect to contribution, the indemnification provided herein by
an Indemnifying Party shall be the exclusive remedy of any and all Indemnified
Parties for the breach of a representation, warranty or agreement hereunder by
an Indemnifying Party; provided, however, that each Indemnified Party shall be
                       --------  -------                                      
entitled to pursue any other remedy at law or in equity for any such breach so
long as the damages sought to be recovered shall not exceed the Losses incurred
thereby resulting from such breach.  In the event that any action or regulatory
proceeding shall be commenced or claim asserted which may entitle an Indemnified
Party to be indemnified under this Agreement, such party shall give the
Indemnifying Party written or telegraphic notice of such action or claim
reasonably promptly after receipt of written notice thereof.  The Indemnifying
Party shall be entitled to participate in and, upon notice to the Indemnified
Party, assume the defense of any such action or claim in reasonable cooperation
with, and with the reasonable cooperation of, the Indemnified Party.  The
Indemnified Party will have the right to employ its own counsel in any such
action in addition to the counsel of the Indemnifying Party, but the fees and
expenses of such counsel will be at the expense of such Indemnified Party,
unless (a) the employment of counsel by the Indemnified Party at its expense has
been authorized in writing by the Indemnifying Party, (b) the Indemnifying Party
has not in fact employed counsel satisfactory to Financial Security to assume
the defense of such action within a reasonable time after receiving notice of
the commencement of the action, or (c) the named parties to any such action or
proceeding (including any impleaded parties) include both the Indemnifying Party
and one or more Indemnified Parties, and the Indemnified Parties shall have been
advised by counsel that (A) there may be one or more legal defenses available to
them which are different from or additional to those available to the
Indemnifying Party and (B) the representation of the Indemnifying Party and such
Indemnified Parties by the same counsel would be inappropriate or contrary to
prudent practice (in which case, if such Indemnified Parties notify the
Indemnifying Party in writing that they elect to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense of such action or proceeding on behalf of such
Indemnified Parties, it being understood, however, that the Indemnifying Party
shall

                                       7
<PAGE>
 
not, in connection with any one such action or proceeding or separate but
substantially similar or related actions or proceedings in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys at any
time for all Seller Parties, one such firm for all Underwriter Parties and one
such firm for all Financial Security Parties, as the case may be, which firm
shall be designated in writing by the Seller in respect of the Seller Parties,
by the Underwriters in respect of the Underwriter Parties and by Financial
Security in respect of the Financial Security Parties), in each of which cases
the fees and expenses of counsel will be at the expense of the Indemnifying
Party and all such fees and expenses will be reimbursed promptly as they are
incurred. The Indemnifying Party shall not be liable for any settlement of any
such claim or action unless the Indemnifying Party shall have consented thereto
or be in default in its obligations hereunder. Any failure by an Indemnified
Party to comply with the provisions of this Section shall relieve the
Indemnifying Party of liability only if such failure is prejudicial to the
position of the Indemnifying Party and then only to the extent of such
prejudice.

     Section 6.  Contribution.
                 ------------ 

          (a)  To provide for just and equitable contribution if the
     indemnification provided by any Indemnifying Party is determined to be
     unavailable for any Indemnified Party (other than due to application of
     this Section), each Indemnifying Party shall contribute to the Losses
     arising from any breach of any of its representations, warranties or
     agreements contained in this Agreement on the basis of the relative fault
     of each of the parties as set forth in Section 6(b) below; provided,
                                                                -------- 
     however, that an Indemnifying Party shall in no event be required to
     -------                                                             
     contribute to all Indemnified Parties an aggregate amount in excess of the
     Losses incurred by such Indemnified Parties resulting from the breach of
     representations, warranties or agreements contained in this Agreement.

          (b)  The relative fault of each Indemnifying Party, on the one hand,
     and of each Indemnified Party, on the other, shall be determined by
     reference to, among other things, whether the breach of, or alleged breach
     of, any representations, warranties or agreements contained in this
     Agreement relates to information supplied by, or action within the control
     of, the Indemnifying Party or the Indemnified Party and the parties'
     relative intent, knowledge, access to information and opportunity to
     correct or prevent such breach.

          (c)  The parties agree that Financial Security shall be solely
     responsible for the Financial Security Information and the Underwriters
     shall be solely responsible for the Underwriter Information and that the
     balance of each Offering Document shall be the responsibility of the
     Seller.

          (d)  Notwithstanding anything in this Section 6 to the contrary, the
     Underwriters shall not be required to contribute an amount in excess of the
     amount by which the total price of the Securities underwritten by the
     Underwriters exceeds the amount of any damages that the 

                                       8
<PAGE>
 
     Underwriters have otherwise been required to pay in respect of such untrue
     statement or omission.

          (e)  No person guilty of fraudulent misrepresentation (within the
     meaning of Section 11(f) of the Securities Act) shall be entitled to
     contribution from any person who was not guilty of such fraudulent
     misrepresentation.

          (f)  Upon the incurrence of any Losses entitled to contribution
     hereunder, the contributor shall reimburse the party entitled to
     contribution promptly upon establishment by the party entitled to
     contribution to the contributor of the Losses incurred.

     Section 7.  Miscellaneous.
                 ------------- 

          (a)  Notices.  All notices and other communications provided for under
               -------

                                   EXHIBIT A


                     OPINION OF ASSISTANT GENERAL COUNSEL


     Based upon the foregoing, I am of the opinion that:

     1.  Financial Security is a stock insurance company duly organized, validly
existing and authorized to transact financial guaranty insurance business under
the laws of the State of New York.

     2.  The Policy and the Financial Security Agreements have been duly
authorized, executed and delivered by Financial Security.

     3.  The Policy and the Financial Security Agreements constitute valid and
binding obligations of Financial Security, enforceable against Financial
Security in accordance with their terms, subject, as to the enforcement of
remedies, to bankruptcy, insolvency, reorganization, rehabilitation, moratorium
and other similar laws affecting the enforceability of creditors' rights
generally applicable in the event of the bankruptcy or insolvency of Financial
Security and to the application of general principles of equity and subject, in
the case of the Indemnification Agreement, to principles of public policy
limiting the right to enforce the indemnification provisions contained therein
insofar as they relate to indemnification for liabilities arising under
applicable securities laws.

     4.  The Policy is exempt from registration under the Securities Act of
1933, as amended (the "Act").
                       ---   

     5.  Neither the execution or delivery by Financial Security of the Policy
or the Financial Security Agreements, nor the performance by Financial Security
of its obligations thereunder, will conflict with any provision of the
certificate of incorporation or the bylaws of Financial Security or violate any
law or regulation, which violation would impair the binding effect or
enforceability of the Policy or any of the Agreements or, to the best of my
knowledge, result in a breach of, or constitute a default under, any agreement
or other instrument to which Financial Security is a party or by which it or any
of its property is bound or, to the best of my knowledge, violate any judgment,
order or decree applicable to Financial Security of any governmental or
regulatory body, administrative agency, court or arbitrator having jurisdiction
over Financial Security (except that in the published opinion of the Securities
and Exchange Commission the indemnification provisions of the Indemnification
Agreement, insofar as they relate to indemnification for liabilities arising
under the Act, are against public policy as expressed in the Act and are
therefore unenforceable).

     In addition, please be advised that I have reviewed the description of
Financial Security under the caption "The Insurer" in the Prospectus (the
                                                                         
"Offering Document") of the Seller with

                                       12

respect to the Securities. The information provided in the Offering Document
with respect to Financial Security is limited and does not purport to provide
the scope of disclosure required to be included in a prospectus with respect to
a registrant under the Act in connection with the public offer and sale of
securities of such registrant. Within such limited scope of disclosure, however,
there has not come to my attention any information which would cause me to
believe that the description of Financial Security referred to above, as of the
date of the Offering Document or as of the date of this opinion, contained or
contains any untrue statement of a material fact or omitted or omits to state a
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading (except that I express
no opinion with respect to any financial statements or other financial
information contained or referred to therein).
