this Section 2.4 or Section 3.02(g) of the Receivables Purchase Agreement.
Neither the Owner Trustee nor the Indenture Trustee shall have any duty to
conduct an affirmative investigation as to the occurrence of any condition
requiring the repurchase of any Receivable pursuant to this Section 2.4 or the
eligibility of any Receivable for purposes of this Agreement.

               (iii)  the original certificate of title for the related Financed

<PAGE>

Trustee, the Indenture Trustee and the Insurer 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.
Nothing herein shall be deemed to require an initial review or any periodic
review by the Trust, the Owner Trustee or the Indenture Trustee of the
Receivable Files, and none of the Trust, the Owner Trustee or the Indenture
Trustee shall be liable or responsible for any action or failure to act by the
Servicer in its capacity as custodian hereunder.

the related accounts, records, and computer systems maintained by the Servicer,
at such times as the Trust or the Indenture Trustee shall instruct.

          (c) Release of Documents.  As soon as practicable after receiving
              --------------------
written instructions from the Indenture Trustee, the Servicer shall release any

              --------------------
in any way attempt to assert any interest in any Receivable held by it as
custodian hereunder or in the related Receivable File other than for collecting
or enforcing such Receivable for the benefit of the Trust.  The entire equitable
interest in such Receivable and the related Receivable File shall at all times
be vested in the Trust.

          SECTION 2.7  Instructions; Authority to Act.  The Servicer 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. A
certified copy of excerpts of authorizing resolutions of the Board of Directors
of the Indenture Trustee 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 the

                                       28
<PAGE>

Servicer of written notice to the contrary given by the Indenture Trustee.

          SECTION 2.8  Indemnification of the Custodian.  The Servicer, in its

capacity as custodian, shall indemnify and hold harmless the Trust, the Owner

                                     --------  -------
not be liable hereunder to the Owner 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 the
Owner Trustee and shall not be liable hereunder to the 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 the Indenture Trustee.

              SECTION 2.9  Effective Period and Termination.  The 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 Section 2.9.
If the Servicer shall resign as Servicer under Section 7.5, or if all of the
rights and obligations of the Servicer shall have been terminated under Section
8.1, the appointment of the Servicer as custodian hereunder may be terminated
(i) by the Trust, with the consent of the Indenture Trustee and the Insurer,

                                  ARTICLE III
                ADMINISTRATION AND SERVICING OF RECEIVABLES AND
                              OTHER TRUST PROPERTY

          SECTION 3.1  Duties of Servicer.  The Servicer shall administer the
                       ------------------
Receivables with reasonable care. The Servicer's duties shall include, but not
be limited to, 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, reporting tax information
to Obligors, furnishing monthly and annual statements to the Owner Trustee and
the Indenture Trustee with respect to distributions and providing collection and
repossession services in the event of Obligor default. In performing its duties
as Servicer hereunder, the Servicer shall use reasonable care and exercise that
degree of skill and attention that the Servicer exercises with respect to all
comparable motor vehicle retail installment sale contracts that it services for
itself or others. Subject to the foregoing and to Section 3.2, the Servicer
shall follow its customary standards, policies, practices and procedures in
performing its duties hereunder as Servicer. Without limiting the generality of
the foregoing, the Servicer is hereby authorized and empowered to execute and
deliver, on behalf of itself, the Depositor, the Trust, the Owner Trustee, the
Indenture Trustee, the Certificateholders, the Noteholders or any one or more of
them, 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 the Financed Vehicles, all in accordance with this Agreement;
provided, however, that, notwithstanding the foregoing, the Servicer shall not,
--------  -------
except pursuant to an order from a court of competent jurisdiction, release an
Obligor from payment of any unpaid amount under any Receivable or waive the
right to collect the unpaid balance (including accrued interest) of any
Receivable from the related Obligor, except in connection with a de minimis
deficiency which the Servicer would not attempt to collect in accordance with
its customary procedures, in which event the Servicer shall indemnify the Trust
for such deficiency. If the Servicer shall commence a legal proceeding to
enforce a Receivable, the Owner Trustee shall thereupon be deemed to have
automatically assigned such Receivable to the

                                       30
<PAGE>

Servicer, which assignment shall be solely for purposes of collection. If in any
enforcement suit or legal proceeding it shall be held that the Servicer may not
enforce a Receivable on the ground that it shall not be a real party in interest
or a holder entitled to enforce such Receivable, the Owner Trustee shall, at the
Servicer's expense and written direction, take steps to enforce such Receivable,
including bringing suit in its name or the names of the Indenture Trustee, the
Certificateholders, the Noteholders or any of them. The Owner Trustee shall
execute and deliver to the Servicer any powers of attorney and other documents
as shall be prepared by the Servicer and reasonably necessary or appropriate to
enable the Servicer to carry out its servicing and administrative duties
hereunder. The Servicer, at its expense, shall obtain on behalf of the Trust or
the Owner Trustee all licenses, if any, required by the laws of any jurisdiction
to be held by the Trust or the Owner Trustee in connection with ownership of the
Receivables and shall make all filings and pay all fees as may be required in
connection therewith during the term hereof.

              SECTION 3.2  Collection and Allocation of Receivable Payments.
                           ------------------------------------------------
The Servicer shall make reasonable efforts to collect all payments called for
under the terms and provisions of the Receivables as and when the same shall
become due and otherwise act with respect to the Receivables and the other Trust
Property in such manner as will, in the reasonable judgment of the Servicer,
maximize the amount to be received by the Trust with respect thereto and in
accordance with the standard of care required by Section 3.1.  The Servicer
shall allocate collections on or in respect of the Receivables between principal
and interest in accordance with the customary servicing practices and procedures
it follows with respect to all comparable motor vehicle retail installment sale
contracts that it services for itself or others.  The Servicer shall not
increase or decrease the number or amount of any Scheduled Payment, the Amount
Financed under any Receivable or the APR of any Receivable, or extend, rewrite
or otherwise modify the payment terms of any Receivable; provided, however, that
                                                         --------  -------
the Servicer may extend the due date for one or more payments due on any
Receivable for credit-related reasons that would be acceptable to the Servicer
with respect to comparable motor vehicle retail installment sale contracts that
it services for itself or others and in accordance with its customary standards,
policies, practices and procedures if the cumulative extensions with respect to
any Receivable shall not cause the term of such Receivable to extend beyond the
Final Scheduled Maturity Date.  If the Servicer fails to comply with the
provisions of the

                                       31
<PAGE>

preceding sentence, the Servicer shall be required to purchase each Receivable
affected thereby for the related Purchase Amount, in the manner specified in
Section 3.7, as of the close of the Collection Period during which such failure
occurs. The Servicer may, in its discretion (but only in accordance with its
customary standards, policies, practices and procedures), waive any late payment
charge or any other fee that may be collected in the ordinary course of
servicing a Receivable.

              SECTION 3.3  Realization upon Receivables. The Servicer shall use
                           ----------------------------
reasonable efforts on behalf of the Trust, in accordance with the standard of
care required under Section 3.1, to repossess or otherwise convert the ownership
of each Financed Vehicle securing a Defaulted Receivable. In taking such action,
the Servicer shall follow such customary practices and procedures as it shall
deem necessary or advisable in its servicing of comparable motor vehicle retail
installment sale contracts and as are otherwise consistent with the standard of
care required under Section 3.1. The Servicer shall be entitled to recover all
reasonable expenses incurred by it in the course of repossessing and liquidating
a Financed Vehicle into cash proceeds, but only out of the cash proceeds of such
Financed Vehicle and any deficiency obtained from the related Obligor. If a
Financed Vehicle shall have suffered damage, the 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 received with respect to the related
Receivable.

              SECTION 3.4  Physical Damage Insurance.  The Servicer shall follow
                           -------------------------
its customary practices and procedures to determine whether or not each Obligor
shall have maintained physical damage insurance covering the related Financed
Vehicle.

              SECTION 3.5  Maintenance of Security Interests in Financed
                           ---------------------------------------------
Vehicles.  The Servicer shall take such steps, in accordance with the standard
--------
of care required under Section 3.1, as are necessary to maintain perfection of
the security interest created by each Receivable in the related Financed
Vehicle. The Trust hereby authorizes the Servicer, and the Servicer hereby
agrees, to take such steps as are necessary to re-perfect such security interest
on behalf of the Trust and the Indenture Trustee in the event the Servicer
receives notice of, or otherwise has actual knowledge of, the fact that such
security interest is not perfected as a result of the relocation of a Financed
Vehicle or for any other reason. The Servicer shall not release, in whole or in
part, any security interest in a

                                       32
<PAGE>

Financed Vehicle created by the related Receivable except as permitted herein or
in accordance with its customary standards, policies, practices and procedures.

              SECTION 3.6  Amendment of Receivable Terms. The Servicer shall
                           -----------------------------
not impair in any material respect the rights of the Depositor, the Trust, the
Owner Trustee, the Indenture Trustee, the Certificateholders, the Noteholders or
the Insurer in the Receivables or, except as permitted under Section 3.2,
otherwise amend or alter the terms of the Receivables if, as a result of such
amendment or alteration, the interests of the Depositor, the Trust, the Owner
Trustee, the Indenture Trustee, the Certificateholders, the Noteholders or the
Insurer hereunder would be materially adversely affected.

              SECTION 3.7  Purchase by Servicer upon Breach.  The Depositor, the
                           --------------------------------
Seller, the Servicer or the Owner Trustee, as the case may be, shall inform the
other parties to this Agreement, the Indenture Trustee and the Insurer promptly,
in writing, upon the discovery of any breach of Section 3.2, 3.5 or 3.6. If such
breach shall not have been cured by the close of business on the last day of the
Collection Period which includes the thirtieth (30th) day after the date on
which the Servicer becomes aware of, or receives written notice from the
Depositor, the Seller, the Owner Trustee or the Insurer of, such breach, and
such breach materially and adversely affects the interest of the Trust in a
Receivable, the Servicer shall purchase such Receivable from the Trust on the
Distribution Date following such Collection Period; provided, however, that,
                                                    --------  -------
with respect to a breach of Section 3.2, the Servicer shall purchase the
affected Receivable from the Trust at the end of the Collection Period in which
such breach occurs. In consideration of the purchase of a Receivable hereunder,
the Servicer shall remit the Purchase Amount of such Receivable in the manner
specified in Section 4.5. The sole remedy of the Trust, the Owner Trustee, the
Indenture Trustee, the Noteholders and the Certificateholders with respect to a
breach of Section 3.2, 3.5 or 3.6 shall be to require the Servicer to purchase
Receivables pursuant to this Section 3.7. Neither the Owner Trustee nor the
Indenture Trustee shall have any duty to conduct an affirmative investigation as
to the occurrence of any condition requiring the purchase of any Receivable
pursuant to this Section 3.7.

              SECTION 3.8  Servicing Compensation.  The Servicer shall receive
                           ----------------------
the Monthly Servicing Fee for servicing the Receivables. The Monthly Servicing
Fee for any Collection Period shall equal the product of one-twelfth (1/12) of
the Servicing Rate and the Pool Balance as of the first day of such

                                       33
<PAGE>

Collection Period (or, in the case of the initial Collection Period, as of the
Closing Date). The Servicer shall pay all expenses incurred by it in connection
with its activities hereunder (including the fees and expenses of the Owner
Trustee and the Indenture Trustee, including the reasonable fees and expenses of
their attorneys, and any custodian appointed by the Owner Trustee and the
Indenture Trustee, the fees and expenses of independent accountants, taxes
imposed on the Servicer and expenses incurred in connection with distributions
and reports to the Certificateholders and the Noteholders), except expenses
incurred in connection with realizing upon Receivables under Section 3.3.

              SECTION 3.9  Servicer's Certificate.  On or before the
                           ----------------------
Determination Date immediately preceding each Distribution Date, the Servicer
shall deliver to the Depositor, the Seller, the Owner Trustee, the Indenture
Trustee, the Insurer and each Paying Agent, with a copy to the Rating Agencies,
a certificate of a Servicing Officer substantially in the form of Exhibit B to
this Agreement (a "Servicer's Certificate") and attached to a Servicer's report
                   ----------------------
containing all information necessary to make the transfers and distributions
pursuant to Sections 4.5, 4.6 and 4.7, together with the written statements to
be furnished by the Owner Trustee to the Certificateholders pursuant to Section
4.9 and by the Indenture Trustee to the Noteholders pursuant to Section 4.9 and
pursuant to Section 6.6 of the Indenture. The Servicer shall separately identify
(by account number) in a written notice to the Depositor, the Owner Trustee, the
Indenture Trustee and the Insurer the Receivables to be repurchased by the
Seller or to be purchased by the Servicer, as the case may be, on the Business
Day preceding such Distribution Date, and, upon request of one of the foregoing
parties, each Receivable which became a Defaulted Receivable during the related
Collection Period. The Servicer shall deliver to the Rating Agencies any
information, to the extent it is available to the Servicer, that the Rating
Agencies reasonably request in order to monitor the Trust.

     Agreement has been made under such officer's supervision; and

               (ii)  to the best of such officer's knowledge, based on such
     review, the Servicer has fulfilled all its obligations under this Agreement
     throughout such Fiscal Year (or, in the case of the Officer's Certificate
     to be delivered in the year 2001, such period) or, if there has been a
     default in the fulfillment of any such obligation, specifying each such
     default known to such officer and the nature and status thereof.

          A copy of such certificate may be obtained by any Certificateholder by
a request in writing to the Owner Trustee, or by any Noteholder or Person
certifying that it is a Note Owner by a request in writing to the Indenture
Trustee, in either case addressed to the applicable Corporate Trust Office.
Upon the written request of the Owner Trustee, the Indenture Trustee shall

also render other services to the Servicer or its Affiliates) to deliver to the
Depositor, the Owner Trustee, the Indenture Trustee and the Insurer a report
addressed to the Board of Directors of the Servicer with respect to the
preceding Fiscal Year (or, in the case of the report to be delivered in the year

statements of the Servicer and issued its report thereon, (ii) such firm has
audited the reports delivered by the Servicer pursuant to Section 3.9 and the
records relating

                                       35

liability in respect of, the sufficiency, validity or correctness of such
procedures.

              SECTION 3.12  Access to Certain Documentation and Information

Regarding Receivables. The Servicer shall provide the Depositor, the Owner

Trustee, the Indenture Trustee, the Certificateholders, the Noteholders and the
Insurer with access to the Receivable Files in the cases where the Depositor,

Noteholders or the Insurer shall be required by applicable statutes or
regulations to have access to such documentation. Such access shall be afforded
without charge, but only upon reasonable request and during normal business

the obligation of the Servicer to observe any applicable law prohibiting
disclosure of information regarding the Obligors, and the failure of the

not constitute a breach of this Section 3.12. Each Certificateholder or
Noteholder, by its acceptance of a Certificate or Note, as the case may be, and
the Insurer shall be deemed to have agreed to keep any information obtained by
it pursuant to this Section 3.12 confidential, except as may be required by
applicable law.

              (a)   The Servicer shall establish, on or before the Closing Date,
and maintain in the name of the Indenture Trustee at an Eligible Institution

Account shall be held in trust for the benefit of the Insurer, the Noteholders
and the Certificateholders. The Collection Account shall be under the sole
dominion and control of the Indenture Trustee; provided, however, that the

Servicer may make deposits to and direct the Indenture Trustee in writing to

Trustee as part of the Trust Property and shall be applied as provided in this
Agreement. All deposits to and withdrawals from the Collection Account shall be
made only upon the terms and conditions of the Transaction Documents.

          If the Servicer is required to remit collections on a daily basis
pursuant to the first sentence of Section 4.2, all amounts held in the
Collection Account shall, to the extent permitted by applicable law, rules and
regulations, be invested, as directed in writing by the Servicer, by the bank or
trust company then maintaining the Collection Account in Permitted Investments

maintained at the Indenture Trustee, the Servicer shall, with the Indenture
Trustee's assistance as necessary, promptly (and in any case within ten (10)
calendar days or such longer period not to exceed thirty (30) calendar days as
to which each Rating Agency may consent) cause the Collection Account to be
moved to an Eligible Institution. The Servicer shall promptly notify the
Indenture Trustee and the Owner Trustee of any change in the account number or
location of the Collection Account.

          (b) The Servicer shall establish, on or before the Closing Date, and
maintain in the name of the Indenture Trustee at an Eligible Institution (which

                                  --------------------
Account shall be held in trust for the benefit of the Noteholders.  The Note
Payment Account shall be under the sole dominion and control of the Indenture
Trustee; provided, however, that the Servicer may make deposits to and direct
         --------  -------
the Indenture Trustee in writing to make withdrawals from the Note Payment
Account in accordance with this Agreement and the Indenture.  All monies
deposited from time to time in the Note Payment Account pursuant to this
Agreement and the Indenture shall be held by the Indenture Trustee as part of
the Trust Property and shall be applied as provided in this Agreement and the
Indenture.  The amounts on deposit in the Note Payment Account shall not be
invested.  If the Note Payment Account is no longer to be maintained at the
Indenture Trustee, the Servicer shall, with the Indenture Trustee's assistance
as necessary, promptly (and in any case within ten (10) calendar days or such
longer period not to exceed thirty (30) calendar days as to which each Rating
Agency may consent) cause the Note Payment Account to be moved to an Eligible
Institution.  The Servicer shall promptly notify the Indenture Trustee and the
Owner Trustee of any change in the account number or location of the Note
Payment Account.

          (c) The Servicer shall establish, on or before the Closing Date, and
maintain in the name of the Owner Trustee at an Eligible Institution (which
shall initially be the Owner Trustee) a segregated trust account designated as
the Certificate Payment Account (the "Certificate Payment Account").  The
                                      ---------------------------
Certificate Payment Account shall be held in trust for the benefit of the
Certificateholders.  The Certificate Payment Account shall be under the sole
dominion and control of the Owner Trustee; provided, however, that the Servicer
                                           --------  -------
may direct

                                       38
<PAGE>

the Indenture Trustee in writing to make deposits to the Certificate Payment
Account in accordance with this Agreement and the Indenture and may direct the
Owner Trustee to make withdrawals from the Certificate Payment Account in
accordance with this Agreement and the Trust Agreement. All monies deposited
from time to time in the Certificate Payment Account pursuant to this Agreement
and the Indenture shall be held by the Owner Trustee as part of the Trust
Property and shall be applied as provided in this Agreement and the Trust
Agreement. The amounts on deposit in the Certificate Payment Account shall not
be invested. If the Certificate Payment Account is no longer to be maintained at
the Owner Trustee, the Servicer shall, with the Owner Trustee's assistance as
necessary, promptly (and in any case within ten (10) calendar days or such
longer period not to exceed thirty (30) calendar days as to which each Rating
Agency may consent) cause the Certificate Payment Account to be moved to an
Eligible Institution. The Servicer shall promptly notify the Indenture Trustee
and the Owner Trustee in writing of any change in the account number or location
of the Certificate Payment Account.

          On each Distribution Date, the Servicer shall instruct the Indenture
Trustee to transfer the Reserve Account Draw Amount, if any, for such
Distribution Date from the Reserve Account to the Collection Account; provided,
                                                                      --------

Indenture. On the Closing Date, the Depositor shall deposit the Initial Reserve
Account Deposit into the Reserve Account from the net proceeds of the sale of

financial assets and other property deposited in or credited to the Reserve
Account (the "Reserve Account Property") has been conveyed by the Depositor to
              ------------------------
the Trust pursuant to Section 2.1(a). Pursuant to the Indenture, the Trust will
pledge all of its right, title and interest in, to and under the Reserve Account
and the Reserve Account Property to the Insurer and to the Indenture Trustee on
behalf of the Noteholders and the Certificateholders to secure its obligations
under the Notes and the Indenture.

          (b)  The Reserve Account Property shall, to the extent permitted by
applicable law, rules and regulations, be invested, as directed in writing by
the Servicer, by the bank or trust company then maintaining the Reserve Account

on funds on deposit in the Reserve Account shall, at the written direction of
the Servicer, be paid to the Seller, as holder of the Residual Interest, on any
Distribution Date to the extent that funds on deposit therein, as certified by
the Servicer, exceed the Required Reserve Account Amount. If the Reserve Account
is no longer to be maintained at the Indenture Trustee, the Servicer shall, with
the Indenture Trustee's assistance as necessary, promptly (and in any case
within ten (10) calendar days or such longer period not to exceed thirty (30)
calendar days as to which each Rating Agency may consent) cause the Reserve
Account to be moved to an Eligible Institution. The Servicer shall promptly
notify the Insurer, the Indenture Trustee and the Owner Trustee in writing of
any change in the account number or location of the Reserve Account.

          (c)  With respect to any Reserve Account Property:

               (i)  any Reserve Account Property that is a "financial asset" as
     defined in Section 8-102(a)(9) of the UCC shall be physically delivered to,
     or credited to an account in the name of, the Eligible Institution
     maintaining the Reserve Account, in accordance with such institution's
     customary procedures such that such institution establishes a "securities
     entitlement" in favor of the Indenture Trustee with respect thereto;

                                       45
<PAGE>

               (ii)  any Reserve Account Property that is held in deposit
     accounts shall be held solely in the name of the Indenture Trustee at one
     or more depository institutions having the Required Rating and each such
     deposit account shall be subject to the exclusive custody and control of
     the Indenture Trustee and the Indenture Trustee shall have sole signature
     authority with respect thereto; and

               (iii) except for any deposit accounts specified in clause (ii)
     above, the Reserve Account shall only be invested in securities or in other
     assets which the Eligible Institution maintaining the Reserve Account
     agrees to treat as "financial assets" as defined in Section 8-102(a)(9) of
     the UCC.

          (d)  If the Reserve Account Amount for any Distribution Date (after
giving effect to the withdrawal of the Reserve Account Draw Amount for such
Distribution Date) exceeds the Required Reserve Account Amount for such
Distribution Date, the Servicer shall instruct the Indenture Trustee in writing
to distribute the amount of such excess to the Seller, as holder of the Residual
Interest. The Indenture Trustee and the Owner Trustee hereby release, on each
Distribution Date, their security interest in, to and under Reserve Account

employees or agents of the Servicer shall be under any liability to the Trust,
the Noteholders or the Certificateholders for any action taken or for refraining
from the taking of any action pursuant to this Agreement or for errors in
judgment; provided, however, that this provision shall not protect the Servicer

prosecute or defend any legal action that shall not 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, however, that the
                                                    --------  -------

however, that no such delegation shall relieve the Servicer of its
-------
responsibilities with respect to such duties and the Servicer shall be solely
responsible for the fees of any such third party; and, provided further, that
                                                       -------- -------

no longer permissible under applicable law. Any such determination permitting
the resignation of the Servicer shall be evidenced by an Opinion of Counsel to
such effect delivered to the Depositor, the Owner Trustee and the Indenture
Trustee. No such resignation shall become effective until the Indenture Trustee
or a successor Servicer shall have (i) assumed the obligations and duties of the
Servicer in accordance with Section 8.2 and (ii) become the Administrator under
the Administration Agreement pursuant to Section 8 thereof.

               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 of the
Servicer, except as otherwise expressly provided herein (including in the
definitions of "Note Balance" and "Certificate Balance") or in the other
Transaction Documents. Except as otherwise expressly

                                       62
<PAGE>

provided herein (including in the definitions of "Note Balance" and "Certificate
Balance") or in the other Transaction Documents, Notes and Certificates so owned

          If an Event of Servicing Termination or a Trigger Event (as defined in
the Insurance Agreement) shall have occurred and be continuing and no Insurer
Default shall have occurred and be continuing, the Indenture Trustee or, if the
Notes have been paid in full, the Owner Trustee, in each case if directed in
writing to do so by the Insurer, by notice then given in writing to the
Depositor and the Servicer, shall terminate all of the rights and obligations of
the Servicer under this Agreement.  If an Event of Servicing Termination shall
have occurred and be continuing and an Insurer Default shall have occurred and
be continuing, the Indenture Trustee or the Holders of Notes evidencing not less
than 51% of the Note Balance or, if the Notes have been paid in full, the Owner
Trustee or the Holders of Certificates evidencing not less than 51% of the
Certificate Balance, in each case by notice then given in writing to the
Depositor, the Servicer and the Insurer (with a copy to the Indenture Trustee
and the Owner Trustee if given by the Noteholders or the Certificateholders),
may terminate all of the rights and obligations of the Servicer under this
Agreement; provided, however, that the indemnification obligations of the
           --------  -------
Servicer under Section 7.2 shall survive such termination.  On or after the
receipt by the Servicer of such written notice, all authority and power of the
Servicer under this Agreement, whether with respect to the Notes, the
Certificates, the Trust Property or otherwise, shall pass to and be vested in
the Indenture Trustee or a successor Servicer appointed under Section 8.2 and,
without limitation, the Indenture Trustee and the Owner Trustee shall be
authorized and empowered to execute and deliver, on behalf of the 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 Receivable Files, the certificates of title to the Financed
Vehicles or otherwise.  The Servicer shall cooperate with the Indenture Trustee,
the Owner Trustee and such successor Servicer in effecting the termination of
its responsibilities and rights as Servicer under this Agreement, including the
transfer to the Indenture Trustee or such successor Servicer for administration
of all cash amounts that are at the time held by the Servicer for deposit or
thereafter shall be received with respect to a Receivable, all Receivable Files
and all information or documents that the Indenture Trustee or such successor
Servicer may require.  In addition, the Servicer shall transfer its electronic
records relating to the Receivables to the successor Servicer in such electronic
form as the successor Servicer may reasonably request.  All

                                       65
<PAGE>

reasonable costs and expenses incurred by the successor Servicer, including
allowable compensation of employees and overhead costs, in connection with the
transfer of servicing shall be paid by the outgoing Servicer (or by the initial
Servicer if the outgoing Servicer is the Indenture Trustee acting on an interim
basis) upon presentation of reasonable documentation of such costs and expenses.

          (b)  The Indenture Trustee and the Owner Trustee shall have no
obligation to notify the Noteholders, the Certificateholders or any other Person
of the occurrence of any event specified in Section 8.1(a) prior to the
continuance of such event through the end of any cure period specified in
Section 8.1(a).

          SECTION 8.2    Indenture Trustee to Act; Appointment of Successor
                         --------------------------------------------------
Servicer.  Upon the resignation of the Servicer pursuant to Section 7.5 or the
--------
termination of the Servicer pursuant to Section 8.1, the Indenture Trustee shall
be the successor in all respects to the Servicer in its capacity as Servicer
under this Agreement and shall be subject to all the obligations and duties
placed on the Servicer by the terms and provisions of this Agreement.  As
compensation therefor, the Indenture Trustee shall be entitled to such
compensation (whether payable out of the Collection Account or otherwise) as the
Servicer would have been entitled to under this Agreement if no such resignation
or termination had occurred, except that all collections on or in respect of the
Receivables shall be deposited in the Collection Account within two (2) Business
Days of receipt and shall not be retained by the Servicer.  Notwithstanding the
foregoing, the Indenture Trustee may, if it shall be unwilling so to act, or
shall, if it is legally unable so to act, appoint, or petition a court of
competent jurisdiction to appoint, an Eligible Servicer as the successor to the
terminated Servicer under this Agreement, subject to the approval of the
Insurer, unless an Insurer Default shall have occurred and be continuing.  In
connection with such appointment, the Indenture Trustee may make such
arrangements for the compensation of such successor Servicer out of collections
on or in respect of the Receivables as it and such successor shall agree, which,
in no event, shall be greater than that payable to CarMax as Servicer hereunder.
The Indenture Trustee and such successor shall take such action, consistent with
this Agreement, as shall be necessary to effectuate any such succession.  The
Indenture Trustee shall not be relieved of its duties as successor Servicer
under this Section 8.2 until a newly appointed Servicer shall have assumed the
obligations and

                                       66
<PAGE>

duties of the terminated Servicer under this Agreement. Notwithstanding anything
to the contrary contained herein, in no event shall the Indenture Trustee be
liable for any servicing fee or for any differential in the amount of the
servicing fee paid hereunder and the amount necessary to induce any successor
Servicer to act as successor Servicer hereunder.

          SECTION 8.3    Effect of Servicing Transfer.
                         ----------------------------

          (a)  After a transfer of servicing hereunder, the Indenture Trustee or
successor Servicer shall notify the Obligors to make directly to the successor
Servicer payments that are due under the Receivables after the effective date of
such transfer.

          (b)  Except as provided in Section 8.2, after a transfer of servicing
hereunder, the outgoing Servicer shall have no further obligations with respect
to the administration, servicing, custody or collection of the Receivables and
the successor Servicer shall have all of such obligations, except that the
outgoing Servicer will transmit or cause to be transmitted directly to the
successor Servicer for its own account, promptly on receipt and in the same form
in which received, any amounts or items held by the outgoing Servicer (properly
endorsed where required for the successor Servicer to collect any such items)
received as payments upon or otherwise in connection with the Receivables.

          (c)  Any successor Servicer shall provide the Depositor and the
Insurer with access to the Receivable Files and to the successor Servicer's
records (whether written or automated) with respect to the Receivable Files.
Such access shall be afforded without charge, but only upon reasonable request
and during normal business hours at the offices of the successor Servicer.

archives) that refer to a Receivable shall indicate clearly and unambiguously
the interest of the Trust and the Indenture Trustee in such Receivable and that
such Receivable is owned by the Trust and has been pledged to the Indenture
Trustee pursuant to the Indenture. Indication of the Trust's and the Indenture

refer in any manner whatsoever to any Receivable, shall indicate clearly and
unambiguously that such Receivable has been sold and is owned by the Trust and
has been pledged to the Indenture Trustee (unless such Receivable has been paid
in full or repurchased by the Seller or purchased by the Servicer).

          Capitalized terms used herein but not otherwise defined shall have the
meanings assigned thereto in the Prospectus Supplement.

is hereby acknowledged, the parties hereto agree as follows:

          1.   MBIA Agreements and Representations. MBIA agrees and represents
               -----------------------------------
as follows:

               (a)  MBIA is a duly incorporated and validly existing New York
     domiciled stock insurance company which is licensed, under the laws of the
     State of New York, to write financial guarantee insurance and is in good
     standing, qualified or licensed to do business in all other jurisdictions
     in which such good standing, qualification or licensing is necessary,
     except for any state where failure to be so qualified, licensed or in good
     standing would not materially and adversely affect MBIA's ability to
     perform its obligations under the Policy.

               (b)  MBIA has the corporate power and authority to issue the
     Policy and execute and deliver this Agreement and the Insurance Agreement
     and to perform all its obligations hereunder and thereunder.

               (c)  The issuance of the Policy and the execution, delivery and
     performance of this Agreement and the Insurance Agreement have been duly
     authorized by all necessary action (corporate and other). No further
     approvals or filings of any kind (other than filing of the Policy with the
     Superintendent of Insurance of the New York State Insurance Department
     within 30 days following the issuance of the Policy), including, without
     limitation, any further approvals of or further filing with any
     governmental agency or other governmental authority, or any approval of
     MBIA's board of directors or stockholders, are necessary for the Policy to
     constitute the legal, valid and binding obligation of MBIA.

               (d)  The Policy, when issued and, assuming due authorization,
     execution and delivery of this Agreement by the parties hereto (other than
     MBIA), this Agreement and the Insurance Agreement, will constitute the
     legal, valid and binding obligations of MBIA, enforceable in accordance
     with their respective terms, subject, as to the enforcement of remedies, to
     (a) applicable bankruptcy, insolvency, reorganization, moratorium and other
     similar laws affecting the enforceability of creditors' rights generally
     and to general principles of equity, in the event of such an occurrence
     with respect to MBIA; (b) the qualification that the remedy of specific
     performance may be subject to equitable defenses and to the discretion of
     the court before which any proceedings with respect thereto may be brought;
     and (c) the enforceability of rights to indemnification under this
     Agreement which may be subject to limitations of public policy under
     applicable securities laws.

               (e)  The MBIA Information in the Prospectus Supplement on the
     date thereof did not, and on January 25, 2001 (the "Closing Date"), will
                                                         ------------
     not, contain any untrue statement of a material fact or omit to state a
     material fact necessary in order to

                                      -2-
<PAGE>

     make the statements therein, in the light of the circumstances under which
     they were made, not misleading.

               (f)  The Policy and any amendments thereto shall be filed with
     the Superintendent of the New York State Insurance Department within 30
     days of their use, if not previously so filed.

               (g)  There are no actions, suits, proceedings or investigations
     pending or, to the best of MBIA's knowledge, threatened against it at law
     or in equity or before or by any court, governmental agency, board or
     commission or any arbitrator which, if decided adversely, would materially
     and adversely affect its condition (financial or otherwise) or operations
     of it or would materially and adversely affect its ability to perform its
     obligations under this Agreement, the Policy or the Insurance Agreement.

               (h)  The consolidated financial statements of MBIA, a wholly
     owned subsidiary of MBIA Inc., and its subsidiaries as of December 31, 1999
     and December 31, 1998 and for each of the three years in the period ended
     December 31, 1999 incorporated by reference in the Prospectus Supplement
     (the "MBIA Audited Financial Statements"), present fairly in all material
           ---------------------------------

     date and for the period covered by such statements in accordance with
     generally accepted accounting principals consistently applied. The
     consolidated financial statements of MBIA and its subsidiaries as of
     September 30, 2000 and for the nine month periods ending September 30, 2000
     and September 30, 1999 incorporated by reference in the Prospectus
     Supplement (the "MBIA Unaudited Financial Statements" and, collectively
                      -----------------------------------
     with the MBIA Audited Financial Statements, the "MBIA Financial
                                                      --------------
     Statements") present fairly in all material respects the financial
     ----------
     condition of MBIA and its subsidiaries as of such date and for the period
     covered by such statements in accordance with generally accepted accounting
     principles applied in a manner consistent with the accounting principles
     used in preparing the MBIA Audited Financial Statements, and, since
     September 30, 2000, there has been no material change in such financial
     condition of MBIA which would materially and adversely affect the ability
     of MBIA to perform its obligations under the Policy.

     reasonably required under the Act and the rules and regulations promulgated
     by the Commission thereunder, which information has been furnished by MBIA
     for inclusion therein and has been approved by MBIA in writing, such
     approval not to be unreasonably withheld.

               (b)  Each of the Underwriters agrees and represents that the
     statements in the Prospectus and Prospectus Supplement were made in
     reliance upon and in conformity with the Underwriting Information (as
     defined in Section 5(c) below), it being

                                      -3-

     Prospectus Supplement did not, and on the Closing Date, will not, contain
     any untrue statement of a material fact or omit to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading.

          3.   Depositor's Representations and Warranties. The Depositor
               ------------------------------------------
represents and warrants the following:

               (a)  The Registration Statement has been filed with, and has been
     declared effective by, the Commission and the Prospectus and the Prospectus
     Supplement have been filed with the Commission.

     Information (as defined in Section 5(c) below) and the Seller Information

     make the statements therein not misleading, and (ii) neither the Prospectus
     nor the Prospectus Supplement on the date thereof did, and on the Closing

     circumstances under which they were made, not misleading.

               (c)  As of the Closing Date, the Depositor's representations and
     warranties contained in the Trust Agreement and the Sale and Servicing
     Agreement are true and correct in all material respects.

               ---------------------------------------
and warrants the following:

               (a)  With respect to the Seller Information, as defined in
     Section 5(b) below, neither the Prospectus nor the Prospectus Supplement on
     the date thereof did, and on the Closing Date neither the Prospectus nor
     the Prospectus Supplement will, contain any untrue statement of a material

     Seller, the Depositor, First Union Corp. and each Underwriter against any
     and all losses, claims, damages or liabilities, joint or several, to which
     they or any of them may become subject under the Act, the Securities
     Exchange Act of 1934, as amended (the "Exchange Act"), any other Federal or
                                            ------------

     insofar as such losses, claims, damages or liabilities (or actions in
     respect

                                      -4-
<PAGE>

     untrue statement of a material fact contained in the MBIA Information

     to the extent approved by MBIA in writing, in any amendment or supplement
     to the Prospectus or the Prospectus Supplement, or arise out of or are
     based upon the omission or alleged omission to state therein a material
     fact necessary in order to make the statements therein, in light of the
     circumstances under which they were made, not misleading, and agrees to
     reimburse each such indemnified party, as incurred, for any legal or other
     expenses reasonably incurred by it in connection with investigating or
     defending any such loss, claim, damage, liability or action. This indemnity
     agreement will be in addition to any liability which MBIA may otherwise
     have.

               (b)  The Seller agrees to indemnify and hold harmless MBIA
     against any and all losses, claims, damages or liabilities, joint or
     several, to which it may become subject under the Act, the Exchange Act,
     any other Federal or state statutory law or regulation, at common law or
     otherwise, as incurred, insofar as such losses, claims, damages or
     liabilities (or actions in respect thereof) arise out of or are based upon

     set forth in the Prospectus under the heading "Material Legal Issues
     Relating to the Receivables" (collectively, the "Seller Information"),
                                                      ------------------
     included in the Prospectus, or in any amendment thereof or supplement
     thereto or in the Prospectus Supplement, or in any amendment thereof or
     supplement thereto, or arise out of or are based upon the omission or
     alleged omission to state in the Seller Information a material fact
     necessary in order to make the statements therein, in light of the
     circumstances under which they were made, not misleading, and agrees to

     statement of a material fact contained in the second, fourth, fifth and
     eleventh paragraphs under the heading "Underwriting" (the "Underwriting
                                                                ------------

     misleading, and agrees to reimburse each such indemnified party, as
     incurred, for any legal or other expenses reasonably incurred by it in

<PAGE>

     liability or action. This indemnity agreement will be in addition to any
     liability which any Underwriter may otherwise have.

               (d)  As an inducement to MBIA to issue the Policy and to enter
     into and facilitate the transactions contemplated hereby, First Union Corp.
     agrees to indemnify and hold harmless MBIA against any and all losses,
     claims, damages or liabilities, joint or several, to which it may become
     subject under the Act, the Exchange Act, any other Federal or state
     statutory law or regulation, at common law or otherwise, as incurred,
     insofar as such losses, claims, damages or liabilities (or actions in
     respect thereof) arise out of or are based upon any untrue statement or
     alleged untrue statement of a material fact contained in the Registration
     Statement, or in any amendment thereof or supplement thereto, or in the
     Prospectus, or in any amendment thereof or supplement thereto or in the
     Prospectus Supplement, or in any amendment thereof or supplement thereto,
     or arise out of or are based upon, in the case of the Registration
     Statement, the omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading, and in the case of the Prospectus or the Prospectus
     Supplement, the omission or alleged omission to state therein a material
     fact necessary in order to make the statements therein, in light of the
     circumstances under which they were made, not misleading, and agrees to
     reimburse each such indemnified party, as incurred, for any legal or other
     expenses reasonably incurred by it in connection with investigating or
     defending any such loss, claim, damage, liability or action; provided,
     however, that First Union Corp. will not be liable in any such case to the
     extent that any such loss, claim, damage or liability arises out of or is
     based upon an untrue statement or alleged untrue statement in or omission
     or alleged omission from any of such documents in reliance upon and in
     conformity with the MBIA Information, the Underwriting Information or the
     Seller Information. This indemnity agreement will be in addition to any
     liability which First Union Corp. may otherwise have.

               (e)  Promptly after receipt by an indemnified party under this
     Section 5 of notice of the commencement of any action, such indemnified
     party will, if a claim in respect thereof is to be made against an
     indemnifying party under this Section 5, notify the indemnifying party in
     writing of the commencement thereof; but the omission so to notify the
     indemnifying party will not relieve it from any liability which it may have
     to any indemnified party except to the extent the indemnifying party is
     prejudiced thereby. In case any such action is brought against any
     indemnified party, and it notifies the indemnifying party of the
     commencement thereof, the indemnifying party will be entitled, at its own
     expense, to participate therein and, to the extent that it may wish,
     jointly with any other indemnifying party similarly notified, to assume the
     defense thereof, with counsel reasonably satisfactory to such indemnified
     party, and, after notice from the indemnifying party to such indemnified
     party to assume the defense of any such action, the indemnifying party will
     not be liable to such indemnified party under this Section 5 for any legal
     or other expenses subsequently reasonably incurred by such indemnified
     party in connection with the defense of any such action other than
     reasonable costs of investigation unless, (i) the defendants in any such
     action include both the indemnified party and the indemnifying party, and
     the indemnified party shall have reasonably concluded that there may be
     legal defenses available to it that are different from or additional to
     those available to the indemnifying party, or one or more

                                      -6-
<PAGE>

     indemnified parties, in which event the indemnified party shall have the
     right to select separate counsel (in addition to any local counsel) to
     assert such legal defenses and to otherwise participate in the defense of
     such action on behalf and under the control of the indemnified party, (ii)
     the indemnifying party shall not have employed counsel reasonably
     satisfactory to the indemnified party to represent the indemnified party
     within a reasonable time after notice of commencement of the action, or
     (iii) the indemnifying party has authorized the employment of counsel for
     the indemnified party at the expense of the indemnifying party; then, in
     any such event, the indemnifying party shall be liable to such indemnified
     party under this Section 5 for any legal and other expenses subsequently
     incurred by such indemnified party in connection with the defense of any
     such action including the reasonable costs of investigation. No
     indemnifying party shall, without the prior written consent of the
     indemnified party, effect any settlement of any pending or threatened
     proceeding in respect of which any indemnified party is or could have been
     a party and indemnity could have been sought hereunder by such indemnified
     party, unless such settlement includes an unconditional release of such
     indemnified party from all liability on claims that are the subject matter
     of such proceeding or threatened proceeding.

               (f)  If the indemnification provided for in this Section 5 is
     unavailable or insufficient to hold harmless an indemnified party under
     subsections (a), (b), (c) or (d) above, then each indemnifying party shall
     contribute to the amount paid or payable by such indemnified party as a
     result of the losses, claims, damages or liabilities referred to in
     subsection (a), (b), (c) or (d) above (i) in such proportion as is
     appropriate to reflect the relative benefits received by the Seller, the
     Depositor (in the case of First Union Corp. as indemnifying party), the
     Underwriters and MBIA from the offering and sale of the Securities or (ii)
     if the allocation provided in clause (i) above is not permitted by
     applicable law, in such proportion as is appropriate to reflect not only
     the relative benefits referred to in clause (i) above but also the relative
     fault of the Seller, the Depositor (in the case of First Union Corp. as
     indemnifying party), the Underwriters and MBIA in connection with the
     statements or omissions that resulted in such losses, claims, damages or
     liabilities, or actions in respect thereof, as well as any other relevant
     equitable considerations. The relative benefits received by the Seller, the
     Depositor (in the case of First Union Corp. as indemnifying party), the
     Underwriters and MBIA shall be deemed to be in the same proportion as (i)
     an amount equal to (x) the aggregate proceeds to the Depositor from the
     sale of the Securities, plus accrued interest and before deducting
     expenses, minus (y) the sum of the purchase price paid by the Depositor to
     the Seller pursuant to Section 2.02 of the Receivables Purchase Agreement
     (the "Purchase Price") (in the case of First Union Corp. as indemnifying
           --------------
     party) bears to (ii) the total premiums received by MBIA, (iii) the
     Purchase Price received by the Seller and (iv) the total underwriting
     discounts to such Underwriter as specified on the cover of the Prospectus
     Supplement in connection with the offering and sale of the Securities, as
     the case may be. Relative fault shall be determined by reference to, among
     other things, whether the untrue or alleged untrue statement of a material
     fact or the omission or alleged omission to state a material fact relates
     to information supplied by the Seller, the Depositor (in the case of First
     Union Corp. as indemnifying party), MBIA, or each of the Underwriters and
     the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such untrue statement or omission. The
     amount paid by an indemnified party as

                                      -7-
<PAGE>

     a result of the losses, claims, damages, or liabilities referred to in the
     first sentence of this subsection (f) shall be deemed to include any legal
     or other expenses reasonably incurred by such indemnified party in
     connection with investigating or defending any action or claim which is the
     subject of this subsection (f). Notwithstanding the provisions of this
     subsection (f), no Underwriter shall be required to contribute to MBIA
     hereunder any amount in excess of the amount of the underwriting discount
     received by it under the Underwriting Agreement. No person guilty of
     fraudulent misrepresentation (within the meaning of Section 11(f) of the
     Act) shall be entitled to contribution from any person who was not guilty
     of such fraudulent misrepresentation.

               (g)  The obligations of First Union Corp. under this Section 5
     shall extend, upon the same terms and conditions, to each person, if any,
     who controls MBIA within the meaning of the Act; and the obligations of the
     Underwriters under this Section shall extend, upon the same terms and
     conditions, to each person, if any, who controls MBIA within the meaning of
     the Act; and the obligations of MBIA under this Section shall extend, upon
     the same terms and conditions, to each director of the Underwriters, the
     Seller and of the Depositor, to each officer of the Underwriters, the
     Seller and the Depositor who has signed the Registration Statement and to
     each person, if any, who controls the Seller, the Depositor or any
     Underwriter within the meaning of the Act.

          6.   Representations and Indemnities to Survive.  The agreements,
               ------------------------------------------
representations, warranties, indemnities and other statements of the parties
hereto in or made pursuant to this Agreement will remain in full force and
