Seller hereby makes the following representations and warranties as to each
Receivable conveyed by it to Issuer hereunder on which Issuer shall rely in

properly executed by the parties thereto and (i) is a Direct Loan made by an

favor of a Seller Affiliate in the Financed Vehicle (subject to administrative
delays and clerical errors on the part of the applicable government agency and

originated in the United States, (ix) constitutes "chattel paper" as defined in
the UCC and (x) has not been identified on the computer files of Wells Fargo's

the Financed Vehicle has no participation in, or other right to receive, any
proceeds of the Receivable; [and (x) no Receivable has Payaheads with respect to
payments due more than ____ months after the Cut-Off Date]. The Receivables were
selected using selection procedures that were not intended by Wells Fargo or
Seller to be adverse to the Holders.

         (c) Schedule of Receivables. The information with respect to each
Receivable set forth in the Schedule of Receivables, including (without
limitation) the account number of the Obligor, the Initial Principal Balance,
and the Contract Rate, was true and correct in all material respects as of the
close of business on the Cutoff Date.

         (d) Compliance with Law. The Receivable complied at the time it was
originated or made, and will comply as of the Closing Date, in all material
respects with all requirements of applicable federal, state and local laws, and
regulations thereunder, including, to the extent applicable, usury laws, the
Federal Truth in Lending Act, the Equal Credit Opportunity Act, the Fair Credit
Billing Act, the Fair Credit Reporting Act, the Federal Trade Commission Act,
the Magnuson-Moss Warranty Act, the Fair Debt Collection Practices Act, Federal
Reserve Board Regulations B and Z and any other consumer credit, consumer
protection, equal opportunity and disclosure laws.

         (e) Binding Obligation. The Receivable constitutes the genuine, legal,
valid and binding payment obligation in writing of the Obligor, enforceable in
all material respects by the holder thereof in accordance with its terms,
subject to the effect of bankruptcy, insolvency, reorganization, or other
similar laws affecting the enforcement of creditors' rights generally, and the
Receivable is not subject to any right of rescission, setoff, counterclaim or
defense, including the defense of usury.

         (f) Lien in Force. Neither Seller nor any Seller Affiliate has taken
any action which would have the effect of releasing the related Financed Vehicle
from the Lien granted by the Receivable in whole or in part.

         (g) No Amendment or Waiver. No material provision of the Receivable has
been amended, waived, altered or modified in any respect, except such waivers as
would be permitted under this Agreement, and no amendment, waiver, alteration or
modification causes such Receivable not to conform to the other representations
or warranties contained in this Section.

         (h) No Liens. Neither Seller nor any Seller Affiliate has received
notice of any Liens or claims, including Liens for work, labor, materials or
unpaid state or federal taxes, relating to the Financed Vehicle securing the
Receivable, that are or may be prior to or equal to the Lien granted by the
Receivable.

         (i) No Default. Except for payment delinquencies continuing for a
period of not more than 30 days as of the Cutoff Date, to the knowledge of
Seller, no default, breach, violation or event permitting acceleration under the
terms of the Receivable exists and no continuing condition that with notice or
lapse of time, or both, would constitute a default, breach, violation or event
permitting acceleration under the terms of the Receivable has arisen.



                                       4

         (j) Insurance. The Receivable requires the Obligor to insure the
Financed Vehicle under a Physical Damage Insurance Policy, pay the premiums for
such insurance and keep such insurance in full force and effect.

         (k) Good Title. It is the intention of Seller that the transfer and
assignment herein contemplated constitute a sale of the Receivables from Seller
to Issuer and that the beneficial interest in and title to the Receivables not
be part of Seller's estate in the event of the filing of a bankruptcy petition
by or against Seller under any bankruptcy law. No Receivable has been sold,
transferred, assigned, or pledged by Seller to any Person other than Issuer.
Immediately prior to the transfer and assignment herein contemplated, Seller had
good and marketable title to the Receivable free and clear of any Lien and had
full right and power to transfer and assign the Receivable to Issuer and
immediately upon the transfer and assignment of the Receivable to Issuer, Issuer
shall have good and marketable title to the Receivable, free and clear of any
Lien; and Issuer's interest in the Receivable resulting from the transfer has
been perfected under the UCC.

         (l) Obligations. Each Seller Affiliate has duly fulfilled all material
obligations on its part to be fulfilled under, or in connection with, the
Receivable.

         (m) Possession. There is only one original executed Receivable, and
immediately prior to the Closing Date, Wells Fargo will have possession of such
original executed Receivable.

         (n) No Government Obligor. The Obligor on the Receivable is not the
United States of America or any state thereof or any local government, or any
agency, department, political subdivision or instrumentality of the United
States of America or any state thereof or any local government.

         (o) Marking Records. By the Closing Date, Seller shall have caused the
portions of Seller's and each Seller Affiliate's electronic master record of
Motor Vehicle Loans relating to the Receivables to be clearly and unambiguously
marked to show that the Receivable is owned by Issuer in accordance with the
terms of this Agreement.

         (p) No Assignment. As of the Closing Date, Seller shall not have taken
any action to convey any right to any Person that would result in such Person
having a right to payments received under the Insurance Policies or Dealer
Agreements, or payments due under the Receivable, that is senior to, or equal
with, that of Issuer.

         (q) Lawful Assignment. The Receivable has not been originated in, and
is not subject to the laws of, any jurisdiction under which the sale, transfer
or assignment of such Receivable hereunder or pursuant to transfers of the Notes
or Certificates are unlawful, void or voidable. Neither Seller nor any Seller
Affiliate has entered into any agreement with any Obligor that prohibits,
restricts or conditions the assignment of any portion of the Receivables.

         (r) Dealer Agreements. A Dealer Agreement for each Receivable is in
effect whereby the Dealer warrants title to the Motor Vehicle and indemnifies
the Seller Affiliate that is a party to said Dealer Agreement against the
unenforceability of each Receivable sold thereunder, and the rights of such
Seller Affiliate thereunder, with regard to the Receivable sold



                                       5
<PAGE>   10

hereunder, have been validly assigned to and are enforceable against the Dealer
by the Seller and then to and by the Issuer, along with any Dealer Recourse.

         (s) Composition of Receivable. No Receivable has a Principal Balance
which includes capitalized interest or late charges.

         (t) Database File. The information included with respect to each
Receivable in the database file delivered pursuant to Section 4.9(b) is accurate
and complete in all material respects.

         SECTION 3.2. Representations and Warranties as to the Receivables in
the Aggregate. Seller hereby makes the following representations and warranties
as to the Receivables conveyed by it to Issuer hereunder on which Issuer shall
rely in acquiring the Receivables. Unless otherwise indicated, such
representations and warranties shall speak as of the Closing Date, but shall
survive the sale, transfer and assignment of the Receivables to Issuer and the
pledge thereof to Indenture Trustee pursuant to the Indenture.

         (a) Amounts. The Original Pool Balance was $_______________.

         (b) Aggregate Characteristics. The Receivables had the following
characteristics in the aggregate as of the Cutoff Date: (i) approximately ____%
of the Original Pool Balance was attributable to loans for purchases of new
Financed Vehicles, and approximately ____% of the Original Pool Balance was
attributable to loans for purchases of used Financed Vehicles; (ii)
approximately ____% of the Original Pool Balance was attributable to Receivables
the mailing addresses of the Obligors with respect to which are located in the
State of ________ and ____% of the Original Pool Balance was attributable to
Receivables the mailing addresses of the Obligors with respect to which are
located in the State of _____, ____% in the State of _______, ____% in the State
of ______, and ____% in the State of ______, and no other state accounts for
more than ____% of the Original Pool Balance; (iii) the weighted average
Contract Rate of the Receivables was _____%; (iv) there are _____ Receivables
being conveyed by Seller to Issuer; (v) the average Cutoff Date Principal
Balance of the Receivables was $______; and (vi) the weighted average original
term and weighted average remaining term of the Receivables were _____ months
and _____ months, respectively.

         SECTION 3.3. Repurchase upon Breach. Seller, Servicer, Indenture
Trustee or Owner Trustee, as the case may be, shall inform the other parties to
this Agreement promptly, in writing, upon the discovery (or, with respect to the
Indenture Trustee or Owner Trustee, upon actual knowledge of a Responsible
Officer) of any breach or failure to be true of the representations or
warranties made by Seller in Section 3.1, provided that the failure to give such
notice shall not affect any obligation of Seller. If the breach or failure shall
not have been cured by the last day of the Collection Period which includes the
60th day (or if Seller elects, the 30th day) after the date on which Seller
becomes aware of, or receives written notice from Owner Trustee, Indenture
Trustee or Servicer of, such breach or failure, and such breach or failure
materially and adversely affects the interests of Issuer and the Holders in any
Receivable, Seller shall repurchase each such affected Receivable from Issuer as
of such last day of such Collection Period at a purchase price equal to the
Purchase Amount for such Receivable as of such last day of such Collection
Period. Notwithstanding the foregoing, any such breach or failure with



                                       6
<PAGE>   11

respect to the representations and warranties contained in Section 3.1 will not
be deemed to have such a material and adverse effect with respect to a
Receivable if the facts resulting in such breach or failure do not affect the
ability of Issuer to receive and retain payment in full on such Receivable. In
consideration of the repurchase of a Receivable hereunder, Seller shall remit
the Purchase Amount of such Receivable, no later than the close of business on
the next Deposit Date, in the manner specified in Section 5.4. The sole remedy
of Issuer, the Owner Trustee, the Indenture Trustee or the Holders with respect
to a breach or failure to be true of the representations or warranties made by
Seller pursuant to Section 3.1 shall be to require Seller to repurchase
Receivables pursuant to this Section.

         SECTION 3.4. Custodian of Receivable Files.

         (a) Custody. To assure uniform quality in servicing the Receivables and
to reduce administrative costs, Issuer, upon the execution and delivery of this
Agreement, revocably appoints Custodian, as agent, and Custodian accepts such
appointment, to act as agent on behalf of Issuer to maintain custody of the
following documents or instruments, which are hereby constructively delivered to
Issuer with respect to each Receivable (collectively, a "Receivable File"):

                  (i) the fully executed original of the Receivable;

                  (ii) any documents customarily delivered to or held by Seller
         or Servicer evidencing the existence of any Physical Damage Insurance
         Policies;

                  (iii) the original credit application, fully executed by the
         Obligor;

                  (iv) the original certificate of title, or such other
         documents as Wells Fargo keeps on file, in accordance with its
         customary procedures, evidencing the security interest of the
         applicable Seller Affiliate in the Financed Vehicle;

                  (v) originals or true copies of all documents, instruments or
         writings relating to extensions, amendments or waivers of the
         Receivable; and

                  (vi) any and all other documents or electronic records that
         Seller, any Seller Affiliate or Servicer, as the case may be, keeps on
         file, in accordance with its customary procedures, relating to the
         Receivable, any Insurance Policies, the Obligor or the Financed
         Vehicle.

         (b) Safekeeping. Servicer, in its capacity as Custodian, shall hold the
Receivable Files as agent on behalf of Issuer and maintain such accurate and
complete accounts, records and computer systems pertaining to each Receivable as
shall enable Servicer and Issuer to comply with the terms and provisions of this
Agreement applicable to them. In performing its duties as Custodian hereunder,
Custodian shall act with reasonable care, exercising the degree of skill,
attention and care that Custodian exercises with respect to receivable files
relating to other similar motor vehicle loans owned and/or serviced by Custodian
and that is consistent with industry standards. In accordance with its customary
practice with respect to its retail installment sale contracts, Custodian shall
conduct, or cause to be conducted, periodic audits of the Receivable Files held
by it under this Agreement, and of the related accounts, records, and



                                       7
<PAGE>   12

computer systems, and shall maintain the Receivable Files in such a manner as
shall enable Owner Trustee to verify, if Owner Trustee so elects, the accuracy
of the record keeping of Custodian. Custodian shall promptly report to Owner
Trustee any failure on its part to hold the Receivable Files and maintain its
accounts, records and computer systems as herein provided, and promptly take
appropriate action to remedy any such failure. Custodian hereby acknowledges
receipt of the Receivable File for each Receivable listed on the Schedule of
Receivables. Nothing herein shall be deemed to require Issuer, Owner Trustee or
Indenture Trustee to verify the accuracy of the record keeping of the Custodian.

         (c) Maintenance of and Access to Records. Custodian shall maintain each
Receivable File at the location specified in Schedule B to this Agreement, or at
such other office of Custodian within the United States (or, in the case of any
successor Custodian, within the State in which its principal place of business
is located) as shall be specified to Issuer by 30 days' prior written notice. At
the reasonable direction of the Owner Trustee or Indenture Trustee, Custodian
shall make available to Owner Trustee, Indenture Trustee and their respective
agents (or, when requested in writing by Owner Trustee or Indenture Trustee,
their respective attorneys or auditors) the Receivable Files and the related
accounts, records and computer systems maintained by Custodian at such times
during the normal business hours of Custodian for purposes of inspecting,
auditing or making copies of abstracts of the same.

         (d) Release of Documents. Upon written instructions from Indenture
Trustee (or, if no Notes are then Outstanding, Owner Trustee), Custodian shall
release any document in the Receivable Files to Indenture Trustee or Owner
Trustee or its respective agent or designee, as the case may be, at such place
or places as Indenture Trustee or Owner Trustee may designate, as soon
thereafter as is practicable. Any document so released shall be handled by
Indenture Trustee or Owner Trustee with due care and returned to Custodian for
safekeeping as soon as Indenture Trustee or Owner Trustee or its respective
agent or designee, as the case may be, shall have no further need therefor.

         (e) Title to Receivables. Custodian agrees that, in respect of any
Receivable File held by Custodian hereunder, Custodian will not at any time have
or in any way attempt to assert any interest in such Receivable File or the
related Receivable, other than solely for the purpose of collecting or enforcing
the Receivable for the benefit of Issuer and that the entire equitable interest
in such Receivable and the related Receivable File shall at all times be vested
in Issuer.

         (f) Instructions; Authority to Act. Custodian shall be deemed to have
received proper instructions with respect to the Receivable Files upon its
receipt of written instructions signed by an Authorized Officer of Indenture
Trustee or Owner Trustee, as applicable. A certified copy of excerpts of certain
resolutions of the Board of Directors of Indenture Trustee or Owner Trustee, as
applicable, shall constitute conclusive evidence of the authority of any such
Authorized Officer to act and shall be considered in full force and effect until
receipt by Custodian of written notice to the contrary given by Indenture
Trustee or Owner Trustee, as applicable.

         (g) Custodian's Indemnification. Custodian shall indemnify and hold
harmless Issuer, Owner Trustee and Indenture Trustee, and each of their
respective officers, directors, employees and agents and the Holders from and
against any and all liabilities, obligations, losses,



                                       8
<PAGE>   13

compensatory damages, payments, costs or expenses (including legal fees if any)
of any kind whatsoever that may be imposed on, incurred or asserted against
Issuer, Owner Trustee, Indenture Trustee or the Holders as the result of any
failure of Custodian to perform its obligations hereunder or any negligent act
or omission of Custodian relating to the maintenance and custody of the
Receivable Files; provided that Custodian shall not be liable hereunder to the
Owner Trustee or Indenture Trustee to the extent that such liabilities,
obligations, losses, compensatory damages, payments, costs or expenses result
from the willful misfeasance, bad faith or negligence of Owner Trustee or
Indenture Trustee, as the case may be. Indemnification under this subsection (g)
shall survive termination of this Agreement and the resignation or removal of
Owner Trustee or Indenture Trustee, as the case may be. If Custodian shall have
made any indemnity payments to Owner Trustee or Indenture Trustee pursuant to
this Section and Owner Trustee or Indenture Trustee thereafter shall collect any
of such amounts from Persons other than Custodian, Owner Trustee or Indenture
Trustee, as the case may be, shall, as soon as practicable following such
receipt thereof, repay such amounts to Custodian, without interest.

         (h) Effective Period and Termination. Servicer's appointment as
Custodian shall become effective as of the Cutoff Date and shall continue in
full force and effect until terminated pursuant to this subsection (h). If
Servicer shall resign as Servicer in accordance with Section 7.5 or if all of
the rights and obligations of Servicer shall have been terminated under Section
8.1, the appointment of Servicer as Custodian hereunder may be terminated by the
Owner Trustee or Indenture Trustee or by the Holders of Notes evidencing not
less than 50% of the aggregate Outstanding Amount of the Notes (or, if no Notes
are then Outstanding, the Holders of Certificates representing not less than 50%
of the Certificate Balance), in each case in the same manner as Owner Trustee or
Indenture Trustee or such Holders may terminate the rights and obligations of
Servicer under Section 8.1. The Indenture Trustee, at the direction of Holders
of Notes evidencing not less than 50% of the aggregate Outstanding Amount of the
Notes, or, if no Notes are then Outstanding, the Owner Trustee at the direction
of Holders of Certificates evidencing not less than 50% of the Certificate
Balance, may terminate Servicer's appointment as Custodian hereunder at any time
with cause. As soon as practicable after any termination of such appointment
Servicer shall deliver, or cause to be delivered, the Receivable Files to
Indenture Trustee or Owner Trustee, as applicable, or its respective agent or
designee at such place or places as Indenture Trustee or Owner Trustee, as
applicable, may reasonably designate. Notwithstanding any termination of
Servicer as Custodian hereunder (other than in connection with a termination
resulting from the termination of Servicer, as such, pursuant to Section 8.1),
from and after the date of such termination, and for so long as Servicer is
acting as such pursuant to this Agreement, Indenture Trustee shall provide, or
cause the successor Custodian to provide, access to the Receivable Files to
Servicer, at such times as Servicer shall reasonably request, for the purpose of
carrying out its duties and responsibilities with respect to the servicing of
the Receivables hereunder.

         (i) Delegation. Custodian may, at any time without notice or consent,
delegate any or all of its duties under the Basic Documents to any Seller
Affiliate; provided that no such delegation shall relieve Custodian of its
responsibility with respect to such duties and Custodian shall remain obligated
and liable to Issuer and the Holders for its duties hereunder as if Custodian
alone were performing such duties.

                                  ARTICLE IV.

                   ADMINISTRATION AND SERVICING OF RECEIVABLES

         SECTION 4.1. Duties of Servicer.

         (a) (i) Servicer is hereby authorized to act as agent for Issuer and in
such capacity shall manage, service, administer and make collections on the
Receivables (other than Purchased Receivables), and perform the other actions
required by Servicer under this Agreement, with reasonable care. Without
limiting the standard set forth in the preceding sentence, Servicer shall use a
degree of skill, attention and care that is not less than Servicer exercises
with respect to comparable Motor Vehicle Loans that it services for itself or
others and that is consistent with prudent industry standards. Servicer's duties
shall include the collection and posting of all payments, responding to
inquiries by Obligors on the Receivables, or by federal, state or local
governmental authorities, investigating delinquencies, sending payment coupons
or monthly invoices to Obligors, reporting required tax information to Obligors,
accounting for Collections, monitoring the status of Physical Damage Insurance
Policies with respect to the Financed Vehicles as provided in Section 4.4(a),
furnishing monthly and annual statements to Owner Trustee and Indenture Trustee
with respect to distributions, providing collection and repossession services in
the event of Obligor default and performing the other duties specified herein.

         (ii) In accordance with its customary servicing procedures, Servicer
shall also administer and enforce all rights and responsibilities of the holder
of the Receivables provided for in the Physical Damage Insurance Policies as
provided in Section 4.4 and the Dealer Agreements. Without limiting the
generality of the foregoing, Servicer is hereby authorized and empowered by
Issuer to execute and deliver, on behalf of itself, Indenture Trustee, Issuer,
Owner Trustee and the Holders, 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 or to the Financed
Vehicles, all in accordance with this Agreement; provided that notwithstanding
the foregoing, 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, except in connection with a de minimis deficiency
which Servicer would not attempt to collect in accordance with its customary
procedures. If Servicer shall commence a legal proceeding to enforce a
Receivable, Issuer shall thereupon be deemed to have automatically assigned such
Receivable to Servicer, which assignment shall be solely for purposes of
collection.

         (b) Servicer may, at any time without notice (except that Servicer
shall give written notice to each Rating Agency of any delegation outside the
ordinary course of business of the substantial portion of its servicing
business) or consent, delegate (i) any or all duties under this Agreement to any
Person more than 50% of the voting securities of which are owned, directly or
indirectly, by Wells Fargo & Company, so long as Wells Fargo acts as Servicer,
or (ii) specific duties to sub-contractors who are in the business of performing
such duties; provided that no such delegation shall relieve Servicer of its
responsibility with respect to such duties and Servicer shall remain obligated
and liable to Issuer and the Holders for servicing and administering the
Receivables in accordance with this Agreement as if Servicer alone were
performing such duties.



                                       10
<PAGE>   15

         SECTION 4.2. Collection of Receivable Payments.

         (a) 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 otherwise act with respect to the Receivables, the
Physical Damage Insurance Policies, the Dealer Agreements and related property
in such manner as will, in the reasonable judgment of Servicer, maximize the
amount to be received by Issuer with respect thereto, in accordance with the
standard of care required by Section 4.1. Servicer shall be entitled to amend or
modify any Receivable in accordance with its customary procedures if Servicer
believes in good faith that such amendment or modification is in Issuer's best
interests; provided that Servicer may not, unless ordered by a court of
competent jurisdiction or otherwise required by applicable law, (i) extend a
Receivable beyond the Final Scheduled Maturity Date or (ii) reduce the Principal
Balance or Contract Rate of any Receivable. If Servicer fails to comply with the
provisions of the preceding sentence, Servicer shall be required to purchase the
Receivable or Receivables affected thereby, for the Purchase Amount, in the
manner specified in Section 4.7 as of the last day of the Collection Period in
which such failure occurs. Servicer may, in its discretion (in accordance with
its customary standards, policies and procedures), waive any prepayment charge,
late payment charge, extension fee or any other fee that may be collected in the
ordinary course of servicing a Receivable.

         (b) If in the course of collecting payments under the Receivables,
Servicer determines to set off any obligation of Servicer to an Obligor against
an amount payable by the Obligor with respect to such Receivable, Servicer shall
deposit the amount so set off in the Collection Account, no later than the close
of business on the Deposit Date for the Collection Period in which the set-off
occurs. All references herein to payments or Liquidation Proceeds collected by
Servicer shall include amounts set-off by Servicer.

         SECTION 4.3. Realization upon Receivables. On behalf of Issuer,
Servicer shall charge off a Receivable in accordance with its customary
standards (and, in no event later than 120 days after a Receivable shall have
become delinquent) and shall use reasonable efforts to repossess and liquidate
the Financed Vehicle securing any Defaulted Receivable as soon as feasible after
such Receivable becomes a Defaulted Receivable, in accordance with the standard
of care required by Section 4.1. In taking such action, Servicer shall follow
such customary and usual practices and procedures as it shall deem necessary or
advisable in its servicing of Motor Vehicle Loans, and as are otherwise
consistent with the standard of care required under Section 4.1, which shall
include exercising any rights under the Dealer Agreements and selling the
Financed Vehicle at public or private sale. 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 or pursuing any deficiency
claim against the related Obligor, but only out of the cash proceeds of such
Financed Vehicle or any deficiency obtained from the Obligor. The foregoing
shall be subject to the provision that, in any case in which a Financed Vehicle
shall have suffered damage, Servicer shall not expend funds in connection with
the repair or the repossession of such Financed Vehicle unless it shall
determine in its discretion that such repair and/or repossession will increase
the Liquidation Proceeds of the related Receivable by an amount equal to or
greater than the amount of such expenses.



                                       11
<PAGE>   16

         If Servicer elects to commence a legal proceeding to enforce a Dealer
Agreement, the act of commencement shall be deemed to be an automatic assignment
from Issuer to Servicer of the rights under such Dealer Agreement. Such
assignment shall be solely for purposes of collection. If, however, in any
enforcement suit or legal proceeding, it is held that Servicer may not enforce a
Dealer Agreement on the grounds that it is not a real party in interest or a
Person entitled to enforce the Dealer Agreement, Owner Trustee, on behalf of
Issuer, at Servicer's expense, or Seller, at Servicer's expense, shall take such
steps as Servicer deems necessary to enforce the Dealer Agreement, including
bringing suit in Issuer's name or the name of Owner Trustee or Indenture
Trustee.

         SECTION 4.4. Physical Damage Insurance.

         (a) The Receivables require that each Financed Vehicle be insured under
a Physical Damage Insurance Policy. Servicer shall monitor or cause to be
monitored, the status of such physical damage insurance coverage to the extent
consistent with its customary servicing procedures. If Servicer shall determine
that an Obligor has failed to obtain or maintain a Physical Damage Insurance
Policy covering the related Financed Vehicle, Servicer shall use reasonable
efforts in accordance with its customary servicing procedures to enforce the
rights of the holder of the Receivable under the Receivable to require the
Obligor to obtain such physical damage insurance, provided that Servicer shall
not be required to take such actions if there is in place a lender's single
interest policy with respect to the related Financed Vehicle that complies with
Servicer's customary requirements. [It is understood that Servicer will not
"force-place" any Physical Damage Insurance Policy on any Financed Vehicle] [TO
BE CONFIRMED].

         (b) Servicer may sue to enforce or collect upon the Physical Damage
Insurance Policies, in its own name, if possible, or as agent for Issuer. If
Servicer elects to commence a legal proceeding to enforce a Physical Damage
Insurance Policy, the act of commencement shall be deemed to be an automatic
assignment of the rights of Issuer under such Physical Damage Insurance Policy
to Servicer for purposes of collection only. If, however, in any enforcement
suit or legal proceeding it is held that Servicer may not enforce a Physical
Damage Insurance Policy on the grounds that it is not a real party in interest
or a holder entitled to enforce the Physical Damage Insurance Policy, Owner
Trustee, on behalf of Issuer, at Servicer's expense, or Seller, at Servicer's
expense, shall take such steps as Servicer deems necessary to enforce such
Physical Damage Insurance Policy, including bringing suit in Issuer's name or
the name of Owner Trustee or Indenture Trustee. Servicer shall make all claims
and enforce its rights under any lender's single interest insurance policy (to
the extent such claims or rights relate to Receivables) for the benefit of the
Issuer and shall treat as Collections all related proceeds of such policies.

         SECTION 4.5. Maintenance of Security Interests in Financed Vehicles.
Servicer, in accordance with the standard of care required under Section 4.1,
shall take such reasonable steps as are necessary to maintain perfection of the
security interest created by each Receivable in the related Financed Vehicle for
the benefit of Issuer and the Indenture Trustee. Issuer hereby authorizes
Servicer, and Servicer hereby agrees, to take such reasonable steps as are
necessary to re-perfect such security interest on behalf of Issuer in the event
Servicer receives notice of the relocation of a Financed Vehicle. If there has
been a Servicer Termination Event, Seller and Servicer, at their expense, shall
promptly and duly execute and deliver such documents and



                                       12
<PAGE>   17

instruments, and take such other reasonable actions as may be necessary, as
evidenced by an Opinion of Counsel delivered to Issuer, Owner Trustee and
Indenture Trustee to perfect Issuer's and Indenture Trustee's interest in the
Trust Property against all other Persons, including the delivery of the
Receivables and the Receivable Files to Indenture Trustee (or Owner Trustee if
no Notes are then Outstanding) its agent or designee, the endorsement and
delivery of the Physical Damage Insurance Policies or the notification of the
insurers thereunder, the execution of transfer instruments, and the endorsement
to Indenture Trustee (or Owner Trustee if no Notes are then Outstanding) and the
delivery of the certificates of title to the Financed Vehicles to the
appropriate department or departments of motor vehicles (or other appropriate
governmental agency).

         SECTION 4.6. Covenants of Servicer. Servicer makes the following
covenants on which Issuer relies in acquiring the Receivables:

         (a) Security Interest to Remain in Force. Servicer shall not release
any Financed Vehicle from the security interest granted by the related
Receivable in whole or in part, except upon payment in full of the Receivable or
as otherwise contemplated herein.

         (b) No Impairment. Servicer shall not impair in any material respect
the rights of the Issuer or the Holders in the Receivables, the Dealer
Agreements or the Physical Damage Insurance Policies or, subject to clause (c),
otherwise amend or alter the terms thereof if, as a result of such amendment or
alteration, the interests of Issuer and the Holders hereunder would be
materially adversely affected.

         (c) Amendments. Servicer shall not amend or otherwise modify any
Receivable (including the grant of any extension thereunder), except in
accordance with Section 4.2.

         SECTION 4.7. Purchase by Servicer upon Breach. Seller, Servicer,
Indenture Trustee or Owner Trustee, as the case may be, shall inform the other
parties promptly, in writing, upon the discovery (or, in the case of the
Indenture Trustee or Owner Trustee, upon actual knowledge of a Responsible
Officer) of any breach by Servicer of its covenants under Section 4.5 or 4.6;
provided that the failure to give such notice shall not affect any obligation of
Servicer. Unless the breach shall have been cured by the last day of the
Collection Period which includes the 60th day (or the 30th day, if Servicer so
elects) after the date on which Servicer becomes aware of, or receives written
notice of, such breach, and such breach materially and adversely affects the
interests of Issuer and the Holders in any Receivable, Servicer shall purchase
such Receivable from Issuer as of the last day of the Collection Period at a
purchase price equal to the Purchase Amount for such Receivable as of the last
day of such Collection Period; provided that in the case of a breach of the
covenant contained in Section 4.6(c), Servicer shall be obligated to purchase
the affected Receivable or Receivables on the Deposit Date immediately
succeeding the Collection Period during which Servicer becomes aware of, or
receives written notice of, such breach. In consideration of the purchase of a
Receivable hereunder, Servicer shall remit the Purchase Amount of such
Receivable in the manner specified in Section 5.4. The sole remedy of Issuer,
Owner Trustee, Indenture Trustee or the Holders against Servicer with respect to
a breach pursuant to Section 4.5 or 4.6 shall be to require Servicer to
repurchase Receivables pursuant to this Section.

         SECTION 4.8. Servicing Fee. The servicing fee for (a) the _____________
[ ], 200_ Payment Date shall equal _______ and (b) for each Payment Date
thereafter shall equal the product of (i) one-twelfth, (ii) the Servicing Fee
Rate and (iii) the Pool Balance as of the opening of business on the first day
of the related Collection Period (the "Servicing Fee"). Servicer shall also be
entitled to retain any late fees, extension fees, prepayment charges (including,
in the case of any Rule of 78's Receivable or Sum of Periodic Balances
Receivable that is prepaid in full, amounts received in excess of the
outstanding Principal Balance of such Receivable and accrued interest thereon
calculated as if such Receivable were an Actuarial Receivable) and certain non-
sufficient funds charges and other administrative fees or similar charges
allowed by applicable law with respect to Receivables collected (from whatever
source) on the Receivables (the "Supplemental Servicing Fee"). It is understood
and agreed that Available Interest or Available Principal shall not include any
amounts retained by Servicer which constitute Supplemental Servicing Fees. The
Servicing Fee in respect of a Collection Period (together with any portion of
the Servicing Fee that remains unpaid from prior Payment Dates), if the Rating
Agency Condition is satisfied, may be paid at the beginning of such Collection
Period out of Collections for such Collection Period. As provided in Section
5.5(c), as additional compensation, Servicer shall be entitled to receive on
each Payment Date, any Additional Servicing for such Payment Date.

         SECTION 4.9. Servicer's Report.

         (a) On each Determination Date, Servicer shall deliver to Owner
Trustee, Indenture Trustee, each Paying Agent and Seller, with a copy to the
Rating Agencies, a Servicer's Report for the immediately preceding Collection
Period, substantially in the form of Exhibit A, containing all information
necessary to make the transfers and distributions pursuant to Sections 5.4, 5.5
and 5.8 on the next Payment Date, together with all information necessary for
the Owner Trustee to send statements to Certificateholders pursuant to Section
5.6 and Indenture Trustee to send copies of statements received by the Indenture
Trustee to Noteholders pursuant to the Indenture and Section 5.6 of this
Agreement. Receivables to be purchased by Servicer or to be repurchased by
Seller shall be identified by Servicer by account number with respect to such
Receivable (as specified in the Schedule of Receivables).

         (b) Servicer shall provide Indenture Trustee with a database file for
the Receivables at or prior to the Closing Date (but with information as of the
close of business on the Cutoff Date).

         SECTION 4.10. Annual Statement as to Compliance; Notice of Default.

         (a) Servicer shall deliver to Owner Trustee, Indenture Trustee and each
Rating Agency, on or before _________ of each year beginning on ________ [ ],
200_, an Officer's Certificate, dated as of ___________ [ ] of the preceding
year, stating that (i) a review of the activities of Servicer during the
preceding 12- month period (or, in the case of the first such report, during the
period from the Closing Date to ____________ [ ], 200_) and of its performance
under this Agreement has been made under such officer's supervision and (ii) to
the best of such officer's knowledge, based on such review, Servicer has
fulfilled all its obligations in all material respects under this Agreement
throughout such year or, if there exists any uncured default in the fulfillment
of any such obligation, specifying each such default known to such



                                       14
<PAGE>   19

officer and the nature and status thereof. A copy of such certificate and the
report referred to in Section 4.11 may be obtained by any Certificateholder by a
request in writing to Owner Trustee addressed to the Corporate Trust Office or
by any Noteholder by a request in writing to Indenture Trustee addressed to the
Corporate Trust Office. Upon the written request of Owner Trustee, Indenture
Trustee will promptly furnish Owner Trustee a list of Noteholders as of the date
specified by Owner Trustee.

         (b) Servicer shall deliver to Owner Trustee, Indenture Trustee and the
Rating Agencies, promptly after having obtained knowledge thereof, but in no
event later than five (5) Business Days thereafter, written notice in an
Officer's Certificate of any event which constitutes, or with the giving of
notice or lapse of time, or both, would become a Servicer Termination Event
under Section 8.1.

         SECTION 4.11. Annual Independent Certified Public Accountants' Report.
(a) The Servicer shall cause a firm of independent certified public accountants
(who may also render other services to the Servicer or Seller) to deliver to the
Seller, Owner Trustee, Indenture Trustee and each Rating Agency on or before
April 30 of each year beginning on ___________________, a report to the effect
that such firm has examined the Servicer's assertion that it has complied with
the [minimum servicing standards set forth in the Mortgage Banker's Association
of America's Uniform Single Attestation Program for Mortgage Bankers ("USAP")]
for the twelve months ended December 31 of the preceding year (or, in the case
of the first such certificate, from the Closing Date until December 31, 200_),
and that such examination (1) included tests relating to the servicing or
administration of the Receivables in accordance with the requirements of the
[USAP], to the extent the procedures in such program apply to the servicing or
administration of the Receivables and (2) except as described in the report,
disclosed no exceptions or errors in the records relating to the servicing or
administration of the Receivables that, in the firm's opinion, paragraph six of
such program requires such firm to report. (b) In the event such firm requires
the Indenture Trustee or Owner Trustee to agree to the procedures performed by
such firm, Servicer shall direct the Indenture Trustee or Owner Trustee, as the
case may be, in writing to so agree; it being understood and agreed that the
Indenture Trustee or Owner Trustee, as the case may be, will deliver such letter
of agreement in conclusive reliance upon the direction of Servicer, and the
Indenture Trustee or Owner Trustee, as the case may be, need not make any
independent inquiry or investigation as to, and shall have no obligation or
liability in respect of, the sufficiency, validity or correctness of such
procedures.

         (c) Such report will also indicate that the firm is independent of
Servicer within the meaning of the Code of Professional Ethics of the American
Institute of Certified Public Accountants.

         SECTION 4.12. Access to Certain Documentation and Information Regarding
Receivables. Servicer shall provide to the Certificateholders, Noteholders, Bank
Regulatory Authorities, and the supervisory agents and examiners of Bank
Regulatory Authorities access to the Receivable Files in such cases where the
Certificateholders, Noteholders or Bank Regulatory Authorities shall be required
by applicable statutes or regulations to review such documentation as
demonstrated by evidence satisfactory to Servicer in its reasonable judgment.
Access shall be



                                       15
<PAGE>   20

afforded without charge, but only upon reasonable request and during the normal
business hours at the respective offices of Servicer. Nothing in this Section
shall affect the obligation of Servicer to observe any applicable law
prohibiting disclosure of information regarding the Obligors and the failure of
Servicer to provide access to information as a result of such obligation shall
not constitute a breach of this Section. Any Holder, by its acceptance of a
Certificate or Note, as applicable, shall be deemed to have agreed to keep any
information obtained by it pursuant to this Section confidential and not to use
such information for any other purpose, except as required by applicable law.

         SECTION 4.13. Reports to the Commission. Servicer shall, on behalf of
the Issuer, cause to be filed with the Commission any periodic reports required
to be filed under the provisions of the Exchange Act, and the rules and
regulations of the Commission thereunder. Seller shall, at its expense,
cooperate in any reasonable request made by Servicer in connection with such
filings.

         SECTION 4.14. Reports to the Rating Agencies. Servicer shall deliver to
each Rating Agency a copy of all reports or notices furnished or delivered
pursuant to this Article and a copy of any amendments, supplements or
modifications to this Agreement and any other information reasonably requested
by such Rating Agency to monitor this transaction.

         SECTION 4.15. Servicer Expenses. Servicer shall be required to pay all
expenses incurred by it in connection with its activities hereunder, including
fees and disbursements of the Owner Trustee, Indenture Trustee, independent
accountants, taxes imposed on Servicer and expenses incurred in connection with
distributions and reports to Certificateholders and Noteholders.

                                   ARTICLE V.

                   DISTRIBUTIONS; RESERVE ACCOUNT; STATEMENTS
                      TO CERTIFICATEHOLDERS AND NOTEHOLDERS

         SECTION 5.1. Establishment of Trust Accounts.

         (a) Servicer shall cause to be established:

                  (i) For the benefit of the Noteholders and the
         Certificateholders, in the name of Indenture Trustee, an Eligible
         Deposit Account (the "Collection Account"), bearing a designation
         clearly indicating that the funds deposited therein are held for the
         benefit of the Noteholders and the Certificateholders.

                  (ii) For the benefit of the Noteholders, in the name of
         Indenture Trustee, 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 Noteholders.

                  (iii) For the benefit of the Noteholders and the
         Certificateholders, in the name of Indenture Trustee, an Eligible
         Deposit Account (the "Payahead Account"), bearing a



                                       16
<PAGE>   21

         designation clearly indicating that the funds therein are held for the
         benefit of the Noteholders and the Certificateholders.

         (b) Funds on deposit in the Collection Account, the Note Distribution
Account, the Payahead Account and the Reserve Account (collectively the "Trust
Accounts") and the Certificate Distribution Account shall be invested by
Indenture Trustee with respect to the Trust Accounts (or any custodian with
respect to funds on deposit in any such account) in Eligible Investments
selected in writing by Servicer (pursuant to standing instructions or
otherwise); provided that it is understood and agreed that neither Servicer,
Indenture Trustee nor Owner Trustee shall be liable for any loss arising from
such investment in Eligible Investments. All such Eligible Investments shall be
held by or on behalf of Indenture Trustee for the benefit of the Noteholders and
the Certificateholders; provided that on each Payment Date all interest and
other investment income (net of losses and investment expenses) on funds on
deposit in the Trust Accounts shall be distributed to Seller and shall not be
available to pay the distributions provided for in Section 5.5 and shall not
otherwise be subject to any claims or rights of Holders. Other than as permitted
by the Rating Agencies, funds on deposit in the Trust Accounts shall be invested
in Eligible Investments that will mature so that such funds will be available at
the close of business on the Deposit Date preceding the next Payment Date. No
Eligible Investment shall be sold or otherwise disposed of prior to its
scheduled maturity unless a default occurs with respect to such Eligible
Investment and Servicer directs Indenture Trustee in writing to dispose of such
Eligible Investment. Funds deposited in a Trust Account on a Deposit Date which
immediately precedes a Payment Date upon the maturity of any Eligible
Investments are not required to be (but are permitted to be) invested overnight.

         (c) Indenture Trustee 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 investment income thereon as provided in Section 5.1(e)) and
all such funds, investments and proceeds 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 Indenture Trustee for the benefit of the
Noteholders and the Certificateholders; provided, however, the Indenture Trustee
shall not be charged with any obligation for the benefit of the
Certificateholders except as provided by the terms of this Agreement. If, at any
time, any of the Trust Accounts or the Certificate Distribution Account ceases
to be an Eligible Deposit Account, Indenture Trustee (or Servicer on its behalf)
or Owner Trustee, as applicable, shall within 10 Business Days (or such longer
period as to which each Rating Agency may consent) establish a new Trust Account
or Certificate Distribution Account, as applicable, as an Eligible Deposit
Account and shall transfer any cash and/or any investments to such new Trust
Account or new Certificate Distribution Account, as applicable. In connection
with the foregoing, Servicer agrees that, in the event that any of the Trust
Accounts are not accounts with Indenture Trustee, Servicer shall notify
Indenture Trustee in writing promptly upon any of such Trust Accounts ceasing to
be an Eligible Deposit Account.

         (d) With respect to the Trust Account Property, the Indenture Trustee
agrees, by its respective acceptance hereof, that:

                  (i) any Trust Account Property that is held in deposit
         accounts shall be held solely in Eligible Deposit Accounts and, except
         as otherwise provided herein, each such Eligible Deposit Account shall
         be subject to the exclusive custody and control of



                                       17
<PAGE>   22

         Indenture Trustee with respect to the Trust Accounts, and, except as
         otherwise provided in the Basic Documents, Indenture Trustee shall have
         sole signature authority with respect thereto;

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

                  (iii) 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 Indenture Trustee
         pending maturity or disposition, through continued book-entry
         registration of such Trust Account Property as described in such
         paragraph; and

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

         (e) Investment earnings attributable to the Trust Account shall be held
by Indenture Trustee for the benefit of Seller. Investment earnings attributable
to the Trust Account shall not be available to pay the distributions provided
for in Section 5.5 and shall not otherwise be subject to any claims or rights of
the Holders or Servicer. Indenture Trustee shall cause all investment earnings
attributable to the Reserve Account to be distributed on each Payment Date to
Seller.

Effective upon Delivery of any Trust Account Property, Indenture Trustee shall
be deemed to have represented that it has purchased such Trust Account Property
for value, in good faith and without notice of any adverse claim thereto.

         SECTION 5.2. Collections.

         (a) Servicer shall remit within two Business Days of receipt thereof to
the Collection Account all payments by or on behalf of the Obligors with respect
to the Receivables (other than any amounts constituting Supplemental Servicing
Fees) and all Liquidation Proceeds, both as collected during the Collection
Period. Notwithstanding the foregoing, if Wells Fargo is the Servicer and (i)
shall have the Required Rating or (ii) Indenture Trustee otherwise shall have
received written notice from each of the Rating Agencies that the then
outstanding rating on the Notes or the Certificates would not be lowered or
withdrawn as a result, Servicer may deposit all amounts referred to above for
any Collection Period into the Collection Account not later than the close of
business on the Deposit Date with respect to such Collection Period; provided
that (i) if a Servicer Termination Event has occurred and is continuing, (ii)
Servicer has been terminated as such pursuant to Section 8.1 or (iii) Servicer
ceases to have the Required Rating, Servicer



                                       18
<PAGE>   23

shall deposit such amounts (including any amounts then being held by Servicer)
into the Collection Account as provided in the preceding sentence. For purposes
of this Article V the phrase "payments by or on behalf of Obligors" shall mean
payments made with respect to the Receivables by Persons other than Servicer,
Seller or any Seller Affiliate.

         (b) With respect to each Receivable (other than a Purchased Receivable
or a Precomputed Receivable), collections and payments by or on behalf of the
Obligor (other than any amounts constituting Supplemental Servicing Fees) for
each Collection Period shall be applied to interest and principal in accordance
with the Simple Interest Method, as applied by Servicer. Any excess shall be
applied to prepay the Receivable. All Liquidation Proceeds shall be treated as
Interest Collections.

         (c) With respect to each Precomputed Receivable, collections and
payments by or on behalf of an Obligor (other than any amounts constituting
Supplemental Servicing Fees) for each Collection Period shall be applied to the
scheduled payments due on such Precomputed Receivable for such Collection
Period. To the extent such collections and payments on a Precomputed Receivable
during a Collection Period exceed the scheduled payment on such Precomputed
Receivable and are insufficient to prepay the Precomputed Receivable in full,
collections shall be treated as Payaheads until such later Collection Period as
such Payaheads may be transferred to the Collection Account and applied either
to the scheduled payments due or to prepay the Precomputed Receivable in full in
accordance with Section 5.5.

         SECTION 5.3. [Reserved].

         SECTION 5.4. Additional Deposits. Servicer and Seller shall deposit or
cause to be deposited in the Collection Account the aggregate Purchase Amounts
with respect to Purchased Receivables and Seller or Servicer shall deposit
therein all amounts, if any, to be paid under Section 9.1. All such deposits
shall be made not later than the Deposit Date following the end of the related
Collection Period.

         SECTION 5.5. Distributions.

         (a) On each Determination Date, Servicer shall calculate all amounts
required to determine the amounts to be deposited on the related Payment Date
from the Reserve Account and the Payahead Account into the Collection Account
and from the Collection Account into the Note Distribution Account, the
Certificate Distribution Account and the Payahead Account.

         (b) On or before each Payment Date, Servicer shall instruct Indenture
Trustee in writing (based on the information contained in the Servicer's Report
delivered on the related Determination Date pursuant to Section 4.9) to, and the
Indenture Trustee shall:

                  (i) withdraw from the Payahead Account and deposit in the
         Collection Account, in immediately available funds, (x) with respect to
         each Precomputed Receivable for which the payments made by or on behalf
         of the Obligor for the related Collection Period are less than the
         scheduled payment for the related Collection Period, the amount of
         Payaheads, if any, made with respect to such Receivable which, when
         added to the amount of such payments, is equal to the amount of such
         scheduled payment, (y) with respect to each Precomputed Receivable for
         which prepayments



                                       19
<PAGE>   24

         insufficient to prepay the Receivable in full have been made by or on
         behalf of the Obligor for the related Collection Period, the amount of
         Payaheads, if any, made with respect to such Receivable which, when
         added to the amount of such prepayments, is equal to an amount
         sufficient to prepay such Receivable in full, and (z) the amount of all
         Payaheads, if any, made with respect to any Purchased Receivable;

                  (ii) withdraw from the Collection Account and deposit in the
         Payahead Account (or receive from the Servicer, which will remit to the
         Indenture Trustee for deposit in the Payahead Account, as the case may
         be), in immediately available funds, the aggregate amount of
         Collections on Precomputed Receivables treated as Payaheads pursuant to
         Section 5.2 for the Collection Period related to such Payment Date; and

                  (iii) withdraw from the Reserve Account and deposit in the
         Collection Account the Reserve Account Transfer Amount, if any, for
         such Payment Date.

         (c) Subject to the last paragraph of this Section 5.5(c), on each
Payment Date, Servicer shall instruct Indenture Trustee in writing (based on the
information contained in the Servicer's Report delivered on the related
Determination Date pursuant to Section 4.9) to make, and Indenture Trustee shall
make, the following deposits and distributions from the Collection Account for
deposit in the applicable account by 11:00 a.m. (New York time), to the extent
of the Total Distribution Amount, in the following order of priority:

                  (i) to Servicer, from the Total Distribution Amount, the
         Servicing Fee for the related Collection Period and all accrued and
         unpaid Servicing Fees for prior Collection Periods;

                  (ii) to the Note Distribution Account, from the Total
         Distribution Amount remaining after the application of clause (i), the
         Noteholders' Interest Distributable Amount;

                  (iii) to the Certificate Distribution Account, from the Total
         Distribution Amount remaining after the application of clause (i) and
         clause (ii), the Certificateholders' Interest Distributable Amount;

                  (iv) to the Note Distribution Account, from the Total
         Distribution Amount remaining after the application of clause (i)
         through clause (iii), the Noteholders' Principal Distributable Amount;

                  (v) to the Note Distribution Account (or, if the Outstanding
         Amount of the Notes has been reduced to zero, to the Certificate
         Distribution Account) for distribution in respect of principal, from
         the Total Distribution Amount remaining after the application of clause
         (i) through clause (iv), the lesser of (A) such remaining Total
         Distribution Amount and (B) the Regular Principal Distributable Amount
         for such Payment Date;

                  (vi) to the Certificate Distribution Account, from the Total
         Distribution Amount remaining after the application of clauses (i)
         through (v), the Certificateholders' Principal Distributable Amount;



                                       20
<PAGE>   25

                  (vii) to the Reserve Account, from the Total Distribution
         Amount remaining after the application of clauses (i) through (vi), the
         lesser of (A) such remaining Total Distribution Amount and (B) the
         amount necessary to cause the amount on deposit in the Reserve Account
         to equal the Specified Reserve Account Balance;

                  (viii) to the Servicer, Additional Servicing for such Payment
         Date; and

                  (ix) to Seller, any amounts remaining.

         Notwithstanding the foregoing, following the occurrence and during the
continuation of an Event of Default which has resulted in an acceleration of the
Notes, the Total Distribution Amount remaining after the application of clause
(i) and (ii) above will be deposited in the Note Distribution Account to the
extent necessary to reduce the principal amount of the Notes to zero in
accordance with and in the priority set forth in Section 5.4 of the Indenture,
and the Certificateholders will not receive any distributions until the
principal amount and accrued interest on the Notes have been paid in full. In
the event that the Collection Account is maintained with an institution other
than Indenture Trustee, Indenture Trustee shall instruct and cause such
institution to make all deposits and distributions pursuant to this Section
5.5(c) on the related Deposit Date.

         (d) Indenture Trustee shall continue to perform its duties under this
Agreement after the Outstanding Amount of the Notes has been reduced to zero and
the Indenture has been discharged in accordance with its terms. The protections,
immunities and standard of care afforded the Indenture Trustee under the
Indenture shall apply to the performance of its duties hereunder.

         SECTION 5.6. Statements to Certificateholders and Noteholders. On each
Determination Date, Servicer shall provide to Indenture Trustee (with a copy to
each Rating Agency) written instructions for Indenture Trustee to forward to
each Noteholder of record, to each Paying Agent, if any, and to Owner Trustee
for Owner Trustee to forward to each Certificateholder of record, a statement
substantially in the form of Exhibit A setting forth at least the following
information as to the Notes and the Certificates to the extent applicable:

         (a) the amount of such distribution allocable to principal of each
class of Notes and to the Certificate Balance of the Certificates;

         (b) the amount of such distribution allocable to interest on or with
respect to each class of Notes and to the Certificates;

         (c) the Pool Balance as of the close of business on the last day of the
preceding Collection Period;

         (d) the aggregate outstanding principal balance of each class of the
Notes, the Note Pool Factor for each such class, the Certificate Balance and the

Servicer, however, will account to Owner Trustee, Indenture Trustee, the
Noteholders and the Certificateholders as if all deposits, distributions and

         SECTION 5.8. Reserve Account.

         (a) Seller shall establish and maintain in the name of the Indenture
Trustee, as agent for the Issuer, the Noteholders and Certificateholders, an
Eligible Deposit Account (the "Reserve Account"). The Reserve Account shall be
initially established and maintained with the Indenture Trustee (the "Securities
Intermediary"). On the Closing Date, Seller shall deposit or cause to be
deposited in the Reserve Account an amount equal to the Reserve Account Deposit.

         (b) Indenture Trustee shall, at the written direction of Servicer,
direct the Securities Intermediary to invest funds on deposit in the Reserve
Account in Eligible Investments selected by Servicer and confirmed in writing by
Servicer to Indenture Trustee; provided that it is understood and agreed that
none of Indenture Trustee, Securities Intermediary, Servicer or Issuer shall be
liable for any loss arising from such investment in Eligible Investments. Funds
on deposit in the Reserve Account shall be invested in Eligible Investments that
will mature so that all such funds will be available at the close of business on
each Deposit Date; provided that to the extent permitted by the Rating Agencies
following written request by Servicer, funds on deposit in the Reserve Account
may be invested in Eligible Investments that mature later than



                                       22
<PAGE>   27

the next Deposit Date. Funds deposited in the Reserve Account on a Deposit Date
upon the maturity of any Eligible Investments are not required to be (but may
be) invested overnight.

         (c) The Securities Intermediary hereby expressly agrees with the
Indenture Trustee that: (i) all matters relating to the Reserve Account shall be
governed by the laws of the State of ___________; (ii) all Eligible Investments
held by the Securities Intermediary on behalf of the Indenture Trustee in the
Reserve Account shall be treated as "financial assets" (as defined in Article 8
of the _________________ Uniform Commercial Code; (iii) the Securities
Intermediary will treat the Indenture Trustee as entitled to exercise the rights
comprising the investments or financial assets credited to the Reserve Account;
(iv) the financial assets credited to the Reserve Account shall not be
registered in the name of, payable to the order of, or specially indorsed to the
Indenture Trustee; and (v) the Securities Intermediary will not agree to comply
with entitlement orders originated by any Person with respect to the investments
or financial assets held in the Reserve Account other than the Indenture
Trustee.

         (d) The Reserve Account shall be under the sole custody and control of
Indenture Trustee. If, at any time, the Reserve Account ceases to be an Eligible
Deposit Account, Indenture Trustee shall within 10 Business Days (or such longer
period, not to exceed 30 calendar days, as to which each Rating Agency may
consent) establish a new Reserve Account as an Eligible Deposit Account and
shall transfer or cause to be transferred any cash and/or any investments that
are in the existing account which is no longer an Eligible Deposit Account to
such new Reserve Account.

         (e) Amounts on deposit in the Reserve Account will be released to
Seller on each Payment Date to the extent that the amount credited to the
Reserve Account would exceed the Specified Reserve Account Balance. Upon any
distribution to Seller of amounts from the Reserve Account, the Holders will not
have any rights in, or claims to, such amounts. Amounts distributed to Seller
from the Reserve Account in accordance with this Section shall not be available
under any circumstances to Issuer, Owner Trustee, Indenture Trustee or the
Holders and Seller shall in no event thereafter be required to refund any such
distributed amounts.

         (f) With respect to the Reserve Account Property, Seller, Issuer and
the Indenture Trustee agree that the Reserve Account Deposit and all other funds
and Reserve Account Property shall be delivered to Indenture Trustee for credit
to the Reserve Account. In addition:

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

                  (ii) any Reserve 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
         Indenture Trustee pending maturity or disposition, through continued
         book entry registration of such Reserve Account Property as described
         in such paragraph; and



                                       23
<PAGE>   28

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

Effective upon the crediting of any Reserve Account Property to the Reserve
Account, Indenture Trustee shall be deemed to have represented that it has
purchased such Reserve Account Property for value, in good faith and without
notice of any adverse claim thereto.

         (g) Issuer and Servicer agree to take or cause to be taken such further
actions, to execute, deliver and file or cause to be executed, delivered and
filed such further documents and instruments (including any UCC financing
statements or this Agreement) as may be determined to be necessary, in an
Opinion of Counsel to Issuer delivered to Owner Trustee and Indenture Trustee in
order to perfect the interests created by this Section 5.8 and otherwise fully
to effectuate the purposes, terms and conditions of this Section 5.8. Issuer and
Servicer shall:

                  (1) promptly execute, deliver and file any financing
         statements, amendments, continuation statements, assignments,
         certificates and other documents with respect to such interests and
         perform all such other acts as may be necessary in order to perfect or
         to maintain the perfection of Indenture Trustee's security interest;
         and

                  (2) make the necessary filings of financing statements or
         amendments thereto within ten days after the occurrence of any of the
         following: (1) any change in their respective names or any trade names,
         (2) any change in the location of their respective chief executive
         offices or principal places of business or jurisdiction of organization
         and (3) any merger or consolidation or other change in their respective
         identities or corporate structures; and shall promptly notify Owner
         Trustee and Indenture Trustee of any such filings.

         (h) Seller may at any time, without consent of Holders, sell, transfer,
convey or assign in any manner its rights to and interests in distributions from
the Reserve Account provided that (i) the Rating Agencies confirm in writing
that such action will not result in a reduction or withdrawal of the rating of
any class of Notes or Certificates, (ii) Seller provides to Owner Trustee and
Indenture Trustee an Opinion of Counsel from independent counsel that such
action will not cause Issuer to be classified as an association (or publicly
traded partnership) taxable as a corporation for federal income tax purposes and
(iii) such transferee or assignee agrees in writing to take positions for
federal income tax purposes consistent with the federal income tax positions
agreed to be taken by Seller.

result of any compensation payable to any subcustodian or subservicer (including
any fees payable in connection with the release of any Receivable File from the
custody of such subservicer or in connection with the termination of the
servicing activities of such subservicer with respect to any Receivable) whether
pursuant to the terms of any subservicing agreement or otherwise.

         (e) Servicer shall indemnify, defend and hold harmless Issuer, Owner
Trustee, Indenture Trustee, Seller, the Certificateholders and the Noteholders
or any of the respective directors, officers, employees and agents of Issuer,
Owner Trustee, Indenture Trustee and Seller from and against any and all costs,

         (f) Servicer shall indemnify, defend and hold harmless Indenture
Trustee and Owner Trustee or any of their respective officers, directors,
employees and agents from any and all costs, expenses, losses, claims, damages
and liabilities (including reasonable attorneys' fees and expenses) to the
extent arising out of the transactions contemplated by the Indenture, the Sale
and Servicing Agreement and the Administration Agreement unless such costs,
expenses, losses, claims, damages and liabilities are due to the negligence,
willful misfeasance or bad faith of the Indenture Trustee or Owner Trustee,
respectively.

Indemnification under this Section shall survive the resignation or removal of
Owner Trustee or Indenture Trustee and the termination of this Agreement or the
Indenture or the Trust Agreement, as applicable, and shall include reasonable
fees and expenses of counsel and other expenses of litigation. If Servicer shall
have made any indemnity payments pursuant to this Section and the Person to or
on behalf of whom such payments are made thereafter shall collect any of such
amounts from others, such Person shall promptly repay such amounts to Servicer,
without interest.

         SECTION 7.3. Merger or Consolidation of, or Assumption of the
Obligations of, Servicer. Any Person (a) into which Servicer may be merged or
consolidated, (b) which may result from any merger or consolidation to which
Servicer shall be a party, (c) which may succeed to the properties and assets of
Servicer, substantially as a whole, or (d) 50% of the voting stock of which is
owned directly or indirectly by Wells Fargo & Company, may become the successor
to Servicer; provided that, unless Wells Fargo is the surviving party to such
transaction, Servicer hereby covenants that it will not consummate any of the
foregoing transactions except upon satisfaction of the following: (i) the
surviving Servicer, if other than Wells Fargo, executes an agreement of
assumption to perform every obligation of Servicer under this Agreement, (ii)
immediately after giving effect to such transaction, no representation or
warranty made pursuant to Section 7.1 shall have been breached and no Servicer
Termination Event, and no event that, after notice or lapse of time, or both,
would become a Servicer Termination Event shall have occurred and be continuing,
(iii) Servicer shall have delivered to Owner Trustee and Indenture Trustee an
Officer's Certificate and an Opinion of Counsel each stating that such
consolidation, merger or succession and such agreement of assumption comply with
this Section and that all conditions precedent, if any, provided for in this
Agreement relating to such transaction have been complied with, and that the
Rating Agency Condition shall have been satisfied with respect to such
transaction, (iv) the surviving Servicer shall have a consolidated net worth at
least equal to that of the predecessor Servicer, and (v) such transaction will
not result in a material adverse Federal or state tax consequence to Issuer, the
Noteholders or the Certificateholders.

         SECTION 7.4. Limitation on Liability of Servicer and Others. Neither
Servicer nor any of its directors, officers, employees or agents shall be under
any liability to Issuer, the Noteholders or the Certificateholders, except as
provided under this Agreement, for any action taken or for refraining from the
taking of any action by Servicer or any subservicer pursuant to this Agreement
or for errors in judgment; provided that this provision shall not protect
Servicer or any such person against any liability that would otherwise be
imposed by reason of willful misfeasance, bad faith or gross negligence in the
performance of duties (except for errors in judgment) or by reason of reckless
disregard of obligations and duties under this Agreement. Servicer or any
subservicer and any of their respective directors, officers, employees or agents



                                       31
<PAGE>   36

may rely in good faith on any document of any kind prima facie properly executed
and submitted by any Person respecting any matters arising under this Agreement.

         Except as provided in this Agreement, Servicer shall not be under any
obligation to appear in, prosecute or defend any legal action that shall be
incidental to its duties to service the Receivables in accordance with this
Agreement, and that in its opinion may involve it in any expense or liability;
provided that Servicer may (but shall not be required to) undertake any
reasonable action that it may deem necessary or desirable in respect of the
Basic Documents to protect the interests of the Certificateholders under this
Agreement and the Noteholders under the Indenture. In such event, the legal
expense and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Servicer.

         SECTION 7.5. Wells Fargo Not To Resign as Servicer. Subject to the
provisions of Section 7.3, Wells Fargo hereby agrees not to resign from the
obligations and duties hereby imposed on it as Servicer under this Agreement
except upon determination that the performance of its duties hereunder shall no
longer be permissible under applicable law or if such resignation is required by
regulatory authorities. Notice of any such determination permitting the
resignation of Wells Fargo as Servicer shall be communicated to Owner Trustee
and Indenture Trustee at the earliest practicable time (and, if such
communication is not in writing, shall be confirmed in writing at the earliest
practicable time) and any such determination shall be evidenced by an Opinion of
Counsel to such effect delivered to Owner Trustee and Indenture Trustee
concurrently with or promptly after such notice. No such resignation shall
become effective until the earlier of Indenture Trustee or a Successor Servicer
having assumed the responsibilities and obligations of the resigning Servicer in
accordance with Section 8.2 or the date upon which any regulatory authority
requires such resignation.

         SECTION 7.6. Existence. Subject to the provisions of Section 7.3,
during the term of this Agreement, Wells Fargo will keep in full force and
effect its existence, rights and franchises as a national banking association.

         SECTION 7.7. Servicer May Own Notes or Certificates. The Servicer, and
any Affiliate of the Servicer, may, in its individual or any other capacity,
become the owner or pledgee of Notes or Certificates with the same rights as it
would have if it were not the Servicer or an Affiliate thereof, except as
expressly provided herein or in any Basic Document. Except as set forth herein
or in the other Basic Documents, Notes and Certificates so owned by or pledged
to Servicer or any such Affiliate shall have an equal and proportionate benefit
under the provisions of this Agreement and the other Basic Documents, without
preference, priority, or distinction as among all of the Notes and Certificates.

                                 ARTICLE VIII.

                           SERVICER TERMINATION EVENTS

         SECTION 8.1. Servicer Termination Event. If any one of the following
events (a "Servicer Termination Event") shall occur and be continuing:



                                       32
<PAGE>   37

         (a) any failure by Servicer to deliver to Indenture Trustee and Owner
Trustee the Servicer's Report in accordance with Section 4.9, or any failure by
Servicer or Seller to deliver to Indenture Trustee or Owner Trustee for deposit
in any of the Trust Accounts or the Certificate Distribution Account any
required payment or to direct Indenture Trustee or Owner Trustee to make any
required distributions therefrom that shall continue unremedied for a period of
five Business Days after written notice of such failure is received by Servicer
from Owner Trustee or Indenture Trustee or after discovery of such failure by an
Authorized Officer of Servicer; or

         (b) failure on the part of Servicer or Seller duly to observe or to
perform in any material respect any other covenants or agreements of Servicer or
Seller, as applicable, set forth in this Agreement or any other Basic Document
to which it is a party, which failure shall (i) materially and adversely affect
the rights of either the Certificateholders or Noteholders and (ii) continue
unremedied for a period of 60 days after the date on which written notice of
such failure, requiring the same to be remedied, shall have been given (A) to
Servicer by Owner Trustee or Indenture Trustee or (B) to Servicer and to Owner
Trustee and Indenture Trustee by the Holders of Notes evidencing not less than
25% of the Outstanding Amount of the Notes or Holders of Certificates evidencing
not less than 25% of the outstanding Certificate Balance, as applicable (or for
such longer period, not in excess of 120 days, as may be reasonably necessary to
remedy such default; provided that such default is capable of remedy within 120
days and Servicer delivers an Officer's Certificate to Owner Trustee and
Indenture Trustee to such effect and to the effect that Servicer or Seller, as
applicable, has commenced or will promptly commence, and will diligently pursue,
all reasonable efforts to remedy such default); or

         (c) an Insolvency Event occurs with respect to Servicer, Seller, any
Seller Affiliate or any of their respective successors;

then, and in each and every case, so long as any Servicer Termination Event
shall not have been remedied, either Indenture Trustee, or the Holders of Notes
evidencing greater than 50% of the Outstanding Amount of the Notes (or, if no
Notes are then Outstanding, either the Owner Trustee or the Holders of
Certificates evidencing greater than 50% of the Certificate Balance), by notice
then given in writing to Servicer (and to Owner Trustee or Indenture Trustee, as
applicable, if given by the Holders) may terminate all the rights and
obligations (other than the obligations set forth in Section 7.2) of Servicer
under this Agreement. On or after the receipt by Servicer of such written
notice, all authority and power of Servicer under this Agreement, whether with
respect to the Notes, the Certificates or the Receivables or otherwise, shall,
without further action, pass to and be vested in Indenture Trustee or such
Successor Servicer as may be appointed under Section 8.2; and, without
limitation, Indenture Trustee and Owner Trustee are hereby authorized and
empowered to execute and deliver, on behalf of the predecessor 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 related documents, or otherwise. The
predecessor Servicer shall cooperate with the Successor Servicer, Indenture
Trustee and Owner Trustee in effecting the termination of the responsibilities
and rights of the predecessor Servicer under this Agreement, including the
transfer to the Successor Servicer for administration by it of all cash amounts
that shall at the time be held by the predecessor Servicer for deposit, or shall
thereafter be received by it with respect to a Receivable. Servicer shall
promptly transfer its electronic records relating to the Receivables to



                                       33
<PAGE>   38

the Successor Servicer in such electronic form as the Successor Servicer may
reasonably request and shall promptly transfer to the Successor Servicer all
other records, correspondence and documents necessary for the continued
servicing of the Receivables in the manner and at such times as the Successor
Servicer shall reasonably request. All reasonable costs and expenses (including
attorneys' fees) incurred in connection with transferring the Receivable Files
to the Successor Servicer and amending this Agreement to reflect such succession
as Servicer pursuant to this Section shall be paid by the predecessor Servicer
upon presentation of reasonable documentation of such costs and expenses. Upon
receipt of notice of the occurrence of a Servicer Termination Event, Indenture
Trustee shall give notice thereof to the Rating Agencies.

         SECTION 8.2. Appointment of Successor.

         (a) Upon Servicer's receipt of notice of termination, pursuant to
Section 8.1 or Servicer's resignation (if and to the extent permitted in
accordance with the terms of this Agreement), the predecessor Servicer shall
continue to perform its functions as Servicer under this Agreement, in the case
of termination, only until the date specified in such termination notice or, if
no such date is specified in a notice of termination, until receipt of such
notice and, in the case of resignation, until the earlier of (i) the date 45
days from the delivery to Owner Trustee and Indenture Trustee of written notice
of such resignation (or written confirmation of such notice) in accordance with
the terms of this Agreement and (ii) the date upon which the predecessor
Servicer shall become unable to act as Servicer, as specified in the notice of
resignation and accompanying Opinion of Counsel. In the event of Servicer's
termination or resignation hereunder, Indenture Trustee shall appoint a
Successor Servicer, and the Successor Servicer shall accept its appointment by a
written assumption in form acceptable to Owner Trustee and Indenture Trustee. In
the event that a Successor Servicer has not been appointed at the time when the
predecessor Servicer has ceased to act as Servicer in accordance with this
Section, Indenture Trustee without further action shall automatically be
appointed the Successor Servicer and Indenture Trustee shall be entitled to the
Servicing Fee. Notwithstanding the above, Indenture Trustee shall, if it shall
be unwilling or unable so to act, appoint or petition a court of competent
jurisdiction to appoint, any established institution, having a net worth of not
less than $50,000,000 and whose regular business shall include the servicing of
motor vehicle receivables, as the successor to Servicer under this Agreement;
provided, that the appointment of any such Successor Servicer will not result in
the withdrawal or reduction of the outstanding rating assigned to the
Certificates or Notes by any Rating Agency.

         (b) Upon appointment, the Successor Servicer (including Indenture
Trustee acting as Successor Servicer) shall be the successor in all respects to
the predecessor Servicer and shall be subject to all the responsibilities,
duties and liabilities arising thereafter relating thereto placed on the
predecessor Servicer and shall be entitled to the Servicing Fee and all the
rights granted to the predecessor Servicer by the terms and provisions of this
Agreement. No Successor Servicer shall be liable for any acts or omissions of
any predecessor Servicer.

         (c) A transfer of servicing hereunder shall not affect the rights and
duties of the parties hereunder (including the obligations and indemnities of
Seller pursuant to Section 3.3 and 6.3 or, with respect to obligations and
indemnities arising prior to, or concurrently with, a transfer of servicing
hereunder, the predecessor Servicer pursuant to Section 4.7 or 7.2) other than
those relating to the management, administration, servicing, custody or
collection of the



                                       34
<PAGE>   39

Receivables and the other rights and properties included in the Owner Trust
Estate. The Successor Servicer shall, upon its appointment pursuant to this
Section 8.2 and as part of its duties and responsibilities under this Agreement,
promptly take all action it deems necessary or appropriate so that the
predecessor Servicer (in whatever capacity) is paid or reimbursed all amounts it
is entitled to receive under this Agreement on each Payment Date subsequent to
the date on which it is terminated as Servicer hereunder. Without limiting the
generality of the foregoing, the predecessor Servicer will be entitled to
receive all accrued and unpaid Servicing Fees through and including the
effective date of the termination of the predecessor Servicer.

         SECTION 8.3. Payment of Servicing Fee. If Servicer shall be replaced,
the predecessor Servicer shall be entitled to receive any accrued and unpaid
Servicing Fees through the date of the Successor Servicer's acceptance hereunder
and any Supplemental Servicing Fees accrued and unpaid or received prior to such
date, in each case, in accordance with Section 4.8.

         SECTION 8.4. Notification to Noteholders and Certificateholders. Upon
any termination of, or appointment of a successor to, Servicer pursuant to this
Article VIII, Owner Trustee shall give prompt written notice thereof to
Certificateholders and Indenture Trustee shall give prompt written notice
thereof to Noteholders subject to the Rating Agency Condition.

         SECTION 8.5. Waiver of Past Defaults. The Holders of Notes evidencing
not less than a majority of the Outstanding Amount of the Notes (or the Holders
of Certificates evidencing not less than a majority of the outstanding
Certificate Balance, as applicable, in the case of any default which does not
adversely affect Indenture Trustee or the Noteholders) may, on behalf of all
Noteholders and Certificateholders, waive in writing any default by Servicer in
the performance of its obligations hereunder and its consequences, except a
default in making any required deposits to any of the Trust Accounts in
accordance with this Agreement. 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.

                                   ARTICLE IX.

                                   TERMINATION

         SECTION 9.1. Optional Purchase of All Receivables; Termination Notice.

         (a) On the last day of any Collection Period immediately preceding a
Determination Date as of which the then outstanding Pool Balance is [10]% or
less of the Original Pool Balance, Seller shall have the option to purchase the
Owner Trust Estate, other than the Trust Accounts, and the Certificate
Distribution Account and any funds or investments therein. To exercise such
option, Seller shall deposit pursuant to Section 5.4 in the Collection Account
an amount which, when added to the amounts on deposit in the Collection Account
for such Payment Date, equals the sum of (a) the unpaid principal amount of the
then outstanding Class B Notes, plus accrued and unpaid interest thereon, plus
(b) the Certificate Balance plus accrued and unpaid interest thereon. The Class
B Notes and the Certificates will be redeemed concurrently therewith.



                                       35
<PAGE>   40

         (b) 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.

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

                                   ARTICLE X.

                            MISCELLANEOUS PROVISIONS

         SECTION 10.1. Amendment.

         (a) This Agreement may be amended by Seller, Servicer, Owner Trustee
and Indenture Trustee (which consent may not be unreasonably withheld), but
without the consent of any of the Noteholders or the Certificateholders:

                  (i) to cure any ambiguity or defect, to correct or supplement
         any provisions in this Agreement or for the purpose of adding any
         provisions to or changing in any manner or eliminating any of the
         provisions in this Agreement or of modifying in any manner the rights
         of the Noteholders or the Certificateholders; provided that such action
         shall not, as evidenced by an Opinion of Counsel delivered to Owner
         Trustee and Indenture Trustee, adversely affect in any material respect
         the interests of any Noteholder or Certificateholder;

                  (ii) (A) to add, modify or eliminate such provisions as may be
         necessary or advisable in order to enable all or a portion of Issuer to
         qualify as, and to permit an election to be made to cause all or a
         portion of Issuer to be treated as, a "financial asset securitization
         investment trust" as described in the provisions of the "Small Business
         Job Protection Act of 1996," or to enable all or a portion of the
         Issuer to qualify and an election to be made for similar treatment
         under such comparable subsequent federal income tax provisions as may
         ultimately be enacted into law, and (B) in connection with any such
         election, to modify or eliminate existing provisions set forth in this
         Agreement relating to the intended federal income tax treatment of the
         Notes or Certificates and Issuer in the absence of the election; it
         being a condition to any such amendment that each Rating Agency will
         have notified the Seller, the Servicer, the Indenture Trustee and the
         Owner Trustee in writing that the amendment will not result in a
         reduction or withdrawal of the rating of any outstanding Notes or
         Certificates with respect to which it is a Rating Agency; and

                  (iii) to add, modify or eliminate such provisions as may be
         necessary or advisable in order to enable (a) the transfer to Issuer of
         all or any portion of the Receivables to be derecognized under
         generally accepted accounting principles ("GAAP") by Seller to Issuer,
         (b) Issuer to avoid becoming a member of Seller's consolidated group
         under GAAP or (c) the Seller, any Seller Affiliate or any of their
         Affiliates to otherwise comply with or obtain more favorable treatment
         under any law or



                                       36
<PAGE>   41

         regulation or any accounting rule or principle; it being a condition to
         any such amendment that each Rating Agency will have notified the
         Seller, the Servicer, the Indenture Trustee and the Owner Trustee in
         writing that the amendment will not result in a reduction or withdrawal
         of the rating of any outstanding Notes or Certificates with respect to
         which it is a Rating Agency.

         (b) This Agreement may also be amended from time to time by Seller,
Servicer, Owner Trustee and Indenture Trustee, with the consent of the Holders
of Notes evidencing not less than a majority of the Outstanding Amount of the
Notes and the consent of the Holders of Certificates evidencing not less than a
majority of the Certificate Balance 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
Certificateholders; provided that no such amendment shall (i) 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 Certificateholders or (ii) reduce the
aforesaid percentage of the Outstanding Amount of the Notes and the Certificate
Balance, the Holders of which are required to consent to any such amendment,
without the consent of the Holders of all the outstanding Notes and the Holders
of all the outstanding Certificates of each class affected thereby.

         (c) Prior to the execution of any such amendment or consent, Servicer
shall furnish written notification of the substance of such amendment or consent
to each Rating Agency. Promptly after the execution of any such amendment or
consent, Servicer shall furnish written notification of the substance of such
amendment or consent to each Noteholder and Certificateholder.

         (d) It shall not be necessary for the consent of Certificateholders 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.

         (e) Prior to the execution of any amendment to this Agreement, Owner
Trustee and Indenture Trustee 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 that all conditions precedent to
the execution and delivery of such amendment have been satisfied and the Opinion
of Counsel referred to in Section 10.2(i)(1) has been delivered. Owner Trustee

amendment which affects Owner Trustee's or Indenture Trustee's, as applicable,
own rights, duties or immunities under this Agreement or otherwise.

         SECTION 10.2. Protection of Title to Trust Property.

         (a) 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

<PAGE>   42

         (b) Neither Seller nor 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 (a) above
seriously misleading within the meaning of (S) 9-402(7) of the UCC, or any
successor provision, unless it shall have given Owner Trustee and Indenture
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.

         (c) Each of Seller and Servicer shall have an obligation to give Owner
Trustee and Indenture Trustee at least 60 days' prior written notice of any
relocation of its principal executive office or jurisdiction of organization,
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 or new financing statement. 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) 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) Servicer shall maintain its computer systems so that, from and
after the time of sale under this Agreement of the Receivables, Servicer's
master computer records (including any backup archives) that refer to a
Receivable shall indicate clearly the interest of Issuer and Indenture Trustee
in such Receivable and that such Receivable is owned by Issuer and has been
pledged to Indenture Trustee pursuant to the Indenture. Indication of Issuer's
and Indenture Trustee's interest in a Receivable shall be deleted from or
modified on Servicer's computer systems when, and only when, the related
Receivable shall have been paid in full or repurchased by Seller or purchased by
Servicer.

         (f) If at any time Seller or 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, 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 Issuer and has been
pledged to Indenture Trustee.

         (g) Servicer shall permit Indenture Trustee, Owner Trustee and their
respective agents at any time during normal business hours to inspect, audit and
make copies of and abstracts from Servicer's records regarding any Receivable.

         (h) Upon request at any time Owner Trustee or Indenture Trustee shall
have reasonable grounds to believe that such request is necessary in connection
with the performance of its duties under this Agreement or any of the Basic
Documents, Servicer shall furnish to Owner Trustee or to Indenture Trustee,

         Agreement and of each amendment thereto, an Opinion of Counsel either
         (A) stating that, in the opinion of such counsel, all financing
         statements and continuation statements have been executed and filed
         that are necessary fully to preserve and protect the interest of Issuer
         and Indenture Trustee in the Receivables, and reciting the details of
