the Trust's delivery of the Securities to, or upon the written order of, the
Seller, the Seller hereby sells, transfers, assigns and conveys to the Trust,
upon the terms and conditions hereof, the Trust Property, without recourse.  The
sale, transfer, assignment and conveyance made hereunder shall not constitute
and is not intended to result in an assumption by any Trustee, the Trust or any
Securityholder of any obligation of the Seller to the Obligors, the Dealers, or
any other Person in connection with the Receivables and the other Trust Property
or any agreement, document or instrument related thereto.

          (b)  The Seller intends that the transfer and conveyance of the Trust
Property to the Trust hereunder constitutes a complete sale and assignment of
all of the Seller's right, title and interest in, to and under the Trust
Property to the Trust and that the beneficial interest of the Seller in, and
title to, the Trust Property will not be a part of the Seller's estate in the
event of any liquidation, reorganization or similar insolvency proceeding with
respect to the Seller.  In the event that the transfer hereunder is not
respected as a complete sale and assignment of the Trust Property to the Trust,
then, in such event, the Seller hereby grants to the Trust a security interest
in all of the Seller's right, title and interest in the Trust Property.  This
Agreement shall constitute a security agreement under applicable law.

     interest)), in each case issued by the appropriate governmental agency of
     the State in which such Financed Vehicle is registered;

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

                         (vi)   in the case of a Dealer Loan, the Dealer
     Assignment; and

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

          Section 2.6    Duties of the Servicer as Custodian. (a) Safekeeping.
                         -----------------------------------      -----------
The Servicer, in its capacity as custodian, shall hold, or cause an Affiliate to
hold, the Receivable Files on behalf of the Trust and the Indenture Trustee for
the benefit of all present and future Securityholders, and maintain such
accurate and complete accounts, records, and computer systems pertaining to each
Receivable as shall enable the Servicer and the Trust and the Trustees to comply
with the terms and

                                      -29-
<PAGE>

provisions of this Agreement applicable to it. In performing its duties as
custodian hereunder, the Servicer shall act with reasonable care, exercising the
degree of skill and care that the Servicer exercises with respect to similar
motor vehicle retail installment sale contracts owned and/or serviced by it and
that is consistent with industry standards. The Servicer shall implement written
policies and procedures, signed by a Servicing Officer, with respect to the
handling and custody of the Receivable Files, so that the integrity and physical
possession of the Receivable Files shall be maintained, and, in general, shall
attend to all details in connection with maintaining custody of the Receivable
Files as agent of the Trust and on behalf of the Indenture Trustee. The Servicer
shall also maintain a current inventory of the Receivables and conduct, or cause
to be conducted, periodic audits (to the extent required by Section 3.11) of the
Receivable Files held by it under this Agreement and the related accounts,
records, and computer systems, and shall otherwise maintain the Receivable Files
in such a manner as shall enable the Owner Trustee to verify, if the Owner
Trustee so elects, the accuracy of the record keeping of the Servicer; provided
that the Indenture Trustee shall have no obligation to perform such verification
unless directed in writing by a majority of the Noteholders. The Servicer shall
promptly report to the Trustees 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.

          (b)  Maintenance of and Access to Records. The Servicer shall
               ------------------------------------
maintain each Receivable File at the location specified in Schedule B to this
Agreement, or at such other office of the Servicer or an Affiliate within the
State of Utah or Idaho (or, in the case of any successor servicer, within the
State in which its principal place of business is located) as shall be specified
to the Trustees by 30 days' prior written notice. The Servicer shall make
available to the Trustees or their Authorized Officers (or, when requested in
writing by either Trustee, to its attorneys or auditors) and to Securityholders
(only in such cases where a Securityholder is required by applicable statutes or
regulations to review such documentation) the Receivable Files and the related
accounts, records, and computer systems maintained by the Servicer at such times
during the normal business hours of the Servicer as the Trustees shall
reasonably instruct.

          (c)  Release of Documents. Upon written instructions from the Trust,
               --------------------
the Servicer shall release any document in the Receivable Files to the Trust,
the Trust's agent, or the Trust's designee, as the case may be, at such place or
places as the Trust may designate, as soon thereafter as is practicable. Any
document so released shall be handled by the Trust with due care and returned to
the Servicer for safekeeping as soon as the Trust or its agent or designee, as
the case may be, shall have no further need therefor.

          (d)  Title to Receivables. The Servicer agrees that, in respect of any
               --------------------
Receivable held by it as custodian hereunder, the Servicer will not at any time
have or in any way attempt to assert any interest in such Receivable or the
related Receivable File, other than solely for the purpose of collecting or
enforcing the Receivable for the benefit of the Trust and that the entire
equitable interest in such Receivable and the related Receivable File shall at
all times be vested in the Trust, subject to the lien of the Indenture Trustee.

          Section 2.7    Instructions; Authority to Act. The Servicer shall be
                         ------------------------------
deemed to have received proper instructions from the Trust with respect to the
Receivable Files upon its receipt of

                                      -30-
<PAGE>

written instructions signed by an Authorized Officer of the Trust (or, as
appropriate, the Owner Trustee on behalf of the Trust). A certified copy of
excerpts of bylaws or certain resolutions of the Board of Directors of the Trust
(or, as appropriate, the Owner Trustee on behalf of the Trust) 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 Servicer of
written notice to the contrary.

          Section 2.8    Custodian's Indemnification. The Servicer, in its
                         ---------------------------
capacity as custodian, shall indemnify and hold harmless the Trust and each
Trustee, their officers, directors, employees and agents and the Securityholders
from and against any and all liabilities, obligations, losses, compensatory
damages, payments, costs or expenses (including legal fees if any) of any kind
whatsoever that may be imposed on, incurred, or asserted against the Trust or
either of the Trustees as the result of any act or omission relating to the
maintenance and custody of the Receivable Files; provided, however, that the
                                                 --------  -------
Servicer shall not be liable hereunder to the extent, but only 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 Trust or any Trustee, respectively.  The obligations of the Servicer, in
its capacity as custodian under this Section 2.8, shall survive the resignation
or removal of the Servicer as custodian under Section 2.9 hereof.

          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 resigns as a 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 by the
Trust or by any Persons to whom the Trust has assigned its rights hereunder, in
the same manner as the Trust or such Persons may terminate the rights and
obligations of the Servicer under Section 7.1.  The Trust may terminate the
Servicer's appointment as a custodian hereunder at any time with cause, or with
30 days' prior notice without cause, upon written notification to the Servicer.
As soon as practicable after any termination of such appointment the Servicer,
at its own expense, shall deliver, or cause to be delivered, the Receivable
Files to the Trust, the Trust's agent or the Trust's designee at such place or
places as the Trust may reasonably designate.  Notwithstanding any termination
of the Servicer as custodian hereunder (other than in connection with a
termination resulting from the termination of the Servicer, as such, pursuant to
Section 7.1), the Trust agrees that, from and after the date of such
termination, and for so long as the Servicer is acting as such pursuant to this
Agreement, the Trust or the Trust's Agent shall provide, or cause the successor
custodian to provide, access to the Receivable Files to the Servicer, at the
times as the Servicer shall request, for the purpose of carrying out its duties
and responsibilities with respect to the servicing of the Receivables hereunder.


                                  ARTICLE III

              ADMINISTRATION AND SERVICING OF THE TRUST PROPERTY

          Section 3.1    Duties of the Servicer. (a) The Servicer, acting alone
                         ----------------------
and/or through subservicers as provided in this Section 3.1, shall administer
the Receivables with reasonable care.

                                      -31-
<PAGE>

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 Trustees with respect to distributions, monitoring the
status of the Insurance Policies with respect to Financed Vehicles and providing
collection and repossession services in the event of Obligor default. The
Servicer shall also administer and enforce all rights and responsibilities of
the holder of the Receivables provided for in the Dealer Agreements, the Dealer
Assignments and the Insurance Policies, to the extent that such Dealer
Agreements, Dealer Assignments and Insurance Policies relate to the Receivables,
the Financed Vehicles or the Obligors. In performing its duties as Servicer
hereunder, the Servicer will exercise that degree of skill and care that the
Servicer exercises with respect to similar motor vehicle retail installment sale
contracts or motor vehicle retail installment loans owned and/or serviced by the
Servicer and that is consistent with prudent industry standards. Without
limiting the generality of the foregoing, the Servicer is hereby authorized and
empowered by the Trust to execute and deliver, on behalf of all Interested
Parties, 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, 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 Obligor, except in connection with a de minimis
                                                             -- -------
deficiency which the servicer would not attempt to collect in accordance with
its customary procedures. If the Servicer shall commence a legal proceeding to
enforce a Receivable, the Trust shall thereupon be deemed to have automatically
assigned such Recievable to the Servicer, which assignment shall be solely for
purposes of collection. The Trust shall furnish the servicer with any powers of
attorney and other documents or instruments necessary or appropriate to enable
the Servicer to carry out its servicing and administrative duties hereunder.

          From time to time during the term of this Agreement, the Servicer may
enter into agreements with (i) one or more Affiliates for the servicing and
administration of certain of the Receivables; provided, however, that any such
                                              --------  -------
subservicer shall be and shall remain, for so long as it is acting as
subservicer, an Eligible Servicer, and any fees paid to such subservicer shall
be paid by the Servicer and not out of the proceeds of the Trust, and any such
subservicer shall agree to service the Receivables in a manner consistent with
the terms of this Agreement or (ii) subcontractors who are in the business of
performing specific duties delegated to it.

          (b)  References in this Agreement to actions taken, to be taken,
permitted to be taken, or restrictions on actions permitted to be taken by the
Servicer in servicing the Receivables and other actions taken, to be taken,
permitted to be taken, or restrictions on actions to be taken with respect to
the Trust Property shall include actions taken, to be taken, permitted to be
taken, or restrictions on actions permitted to be taken by a subservicer or
subcontractor on behalf of the Servicer and references herein to payments,
Recoveries  or Liquidation Proceeds received by the Servicer shall include
payments, Recoveries or Liquidation Proceeds received by a subservicer or
subcontractor, irrespective of whether such payments, Recoveries or Liquidation
Proceeds are actually deposited in the Collection Account by such subservicer or
subcontractor.  Any subservicing agreement will contain terms and provisions
substantially identical to the terms and provisions of

                                      -32-
<PAGE>

this Agreement and such other terms and provisions as are not inconsistent with
this Agreement and as the Servicer and the subservicer have agreed.

          (c)  The Servicer shall be entitled to terminate any subservicing or
subcontracting agreement in accordance with the terms and conditions of such
subservicing or subcontracting agreement and without any limitation by virtue of
this Agreement; provided, however, that, in the event of termination of any
                --------  -------
subservicing or subcontracting agreement by the Servicer, the Servicer shall
either act directly as servicer of the related Receivable or enter into a
subservicing or subcontracting agreement with a successor subservicer or
subcontractor which will be bound by the terms of the related subservicing or
subcontracting agreement.

          (d)  As a condition to the appointment of any subservicer other than
an Affiliate of the Seller, the Servicer shall notify each Trustee in writing
and the Rating Agencies before such assignment becomes effective and such
subservicer shall be required to execute and deliver an instrument in which it
agrees that, for so long as it acts as subservicer of the Receivables and the
other Trust Property being serviced by it, the covenants, conditions,
indemnities, duties, obligations and other terms and provisions of this
Agreement applicable to the Servicer hereunder shall be applicable to it as
subservicer, that it shall be required to perform its obligations as subservicer
for the benefit of the Trust as if it were the Servicer hereunder (subject,
however, to the right of the Servicer to direct the performance of such
obligations in accordance with this Agreement) and that, notwithstanding any
provision of a subservicing agreement to the contrary, such subservicer shall be
directly liable to the Trust (notwithstanding any failure by the Servicer to
perform its duties and obligations hereunder) for the failure by such
subservicer to perform its obligations hereunder or under any subservicing
agreement, and that (notwithstanding any failure by the Servicer to perform its
respective duties and obligations hereunder) the Trust may enforce the
provisions of this Agreement and any subservicing agreement against the
subservicer, without diminution of such obligations or liabilities by virtue of
any subservicing agreement, by virtue of any indemnification provided thereunder
or by virtue of the fact that the Servicer is primarily responsible hereunder
for the performance of such duties and obligations, as if a subservicer alone
were servicing and administering, under this Agreement, the Receivables and the
other Trust Property being serviced by it under the subservicing agreement.

          (e)  Notwithstanding any subservicing or subcontracting agreement, any
of the provisions of this Agreement relating to agreements or arrangements
between the Servicer or a subservicer or subcontractor or reference to actions
taken through such Persons or otherwise, the Servicer shall remain obligated and
liable to the Trust, each Trustee and the Securityholders for the servicing and
administering of the Receivables and the other Trust Property in accordance with
the provisions of this Agreement (including for the deposit of payments,
Recoveries and Liquidation Proceeds received by a subservicer or subcontractor,
irrespective of whether such payments, Recoveries or Liquidation Proceeds are
actually remitted to the Servicer or deposited in the Collection Account by such
subservicer or subcontractor; provided that if such amounts are so deposited,
                              --------
the Servicer shall have no further obligation to do so) without diminution of
such obligation or liability by virtue of such subservicing or subcontracting
agreements or arrangements or by virtue of indemnification from a subservicer or
subcontractor, to the same extent and under the same terms and conditions as if
the Servicer alone were servicing and administering the Receivables

                                      -33-
<PAGE>

and the other Trust Property. The Servicer shall be entitled to enter into any
agreement with a subservicer or subcontractor for indemnification of the
Servicer, and nothing contained in this Agreement shall be deemed to limit or
modify such indemnification.

          (f)  In the event the Servicer shall for any reason no longer be
acting as such (including by reason of the occurrence of an Event of Servicing
Termination), the successor servicer may, in its discretion, thereupon assume
all of the rights and obligations of the outgoing Servicer under a subservicing
agreement. In such event, the successor servicer shall be deemed to have assumed
all of the outgoing Servicer's interest therein and to have replaced the
outgoing Servicer as a party to such subservicing agreement to the same extent
as if such subservicing agreement had been assigned to the successor servicer,
except that the outgoing Servicer shall not thereby be relieved of any liability
or obligation on the part of the outgoing Servicer to the subservicer under such
subservicing agreement. The outgoing Servicer shall, upon request of the Trust,
but at the expense of the outgoing Servicer, deliver to the successor servicer
all documents and records relating to each such subservicing agreement and the
Receivables and the other Trust Property then being serviced thereunder and an
accounting of amounts collected and held by it and otherwise use its best
efforts to effect the orderly and efficient transfer of the subservicing
agreement to the successor servicer. In the event that the successor servicer
elects not to assume a subservicing agreement, the outgoing Servicer, at its
expense, shall cause the subservicer to deliver to the successor servicer all
documents and records relating to the Receivables and the other Trust Property
being serviced thereunder and all amounts held (or thereafter received) by such
subservicer (together with an accounting of such amounts) and shall otherwise
use its best efforts to effect the orderly and efficient transfer of servicing
of the Receivables and the other Trust Property being serviced by such
subservicer to the successor servicer. The relationship of the Servicer (and of
any successor to the Servicer as servicers under this Agreement) to the Trust
under this Agreement is intended by the parties to be that of independent
contractors and not that of joint venturers, partners or agents.

          Section 3.2    Collection of Receivable Payments; Credit Deferrals;
                         ----------------------------------------------------
Optional Payment Deferrals.  (a) 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, the Dealer Agreements, the Dealer Assignments, the
Insurance Policies 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, in accordance with the standard of care required by
Section 3.1.  The Servicer shall be entitled to amend or modify any Receivable
in accordance with its customary procedures if the Servicer believes in good
faith that such amendment or modification is in the best interests of the Trust;
provided, however, that the Servicer may not (i) extend a Receivable beyond the
--------  -------
last day of the Collection Period immediately preceding the Final Scheduled
Distribution Date for the Class B Notes; or (ii) amend or modify the Principal
Balance or Contract Rate of any Receivable, except as required by court order or
applicable law.

          (b)  The Servicer may grant to an Obligor one or more payment
deferrals (each, a "Credit Deferral") if (i) the Servicer determines that,
                    ---------------
absent such deferral, a payment default by the Obligor is reasonably
foreseeable; (ii) the Servicer would grant such Credit Deferral if the
Receivable were serviced by it for its own account and in accordance with its
customary standards;

                                      -34-
<PAGE>

(iii) the cumulative extensions with respect to any Receivable shall not cause
the term of such Receivable to extend beyond the last day of the Collection
Period immediately preceding the Final Scheduled Distribution Date for the Class
B Notes; (iv) such extensions in the aggregate do not exceed two months during
any twelve-month period; and (v) interest continues to accrue on the outstanding
Receivable Balance of the Receivable during the term of such Credit Deferral.
The Servicer may charge a fee in connection with the grant of Credit Deferrals
in accordance with its customary practices and procedures, which fee shall be
added to the Receivable Balance of the related Receivable. In the event that the
Servicer fails to comply with the provisions of the first sentence of this
Section 3.2(b), the Servicer shall be required to purchase the Receivable or
Receivables affected thereby in accordance with Section 3.7 hereof.

          (c)  On or after the Closing Date, the Servicer shall notify each
Obligor meeting the requirements set forth below, in writing, at least three
weeks prior to the first month with respect to which such Obligor would be
entitled to an optional extension pursuant to this Section 3.2(c), that such
qualifying Obligor, at such Obligor's option during the remaining term of the
Receivable, shall be entitled to a non-credit related extension of any regularly
scheduled payment due under a Receivable (each, an "Optional Payment Deferral")
                                                    -------------------------
if such qualifying Obligor satisfies the following conditions:

               (i)       at the time of such extension, such Receivable shall
     not have been the subject of two such Optional Payment Deferrals in the
     related fiscal year of the Trust;

               (ii)      such Receivable shall (x) not have been the subject of
     any Credit Deferral within 90 days of the related Optional Payment
     Deferral, or (y) not have been the subject of more than two Credit
     Deferrals since its date of origination;

               (iii)     at the time of such Optional Payment Deferral, the
     Receivable shall not have been more than 30 days past due three times or
     more;

               (iv)      at the time of such Optional Payment Deferral, the
     Receivable shall not be more than 15 days or more delinquent;

               (v)       at the time of such Optional Payment Deferral, (i) at
     least 6 months of the Receivable's original term shall have elapsed, or
     (ii) at least [20%] of the Receivable's original term shall have elapsed,
     whichever is less; and

               (vi)      in the reasonable judgment of the Servicer, the
     Receivable is not likely to become a Liquidating Receivable following such
     Optional Payment Deferral.

          The Servicer may charge a fee in connection with the grant of Optional
Payment Deferrals in accordance with its customary practices and procedures,
which fee shall be added to the Receivable Balance of the related Receivable.
If, as an inadvertent result of any extension granted pursuant to this Section
3.2(c), such extension breached any of the terms of the preceding criteria (i)
through (vi) or caused the term of such Receivable to extend beyond the last day
of the Collection

                                      -35-
<PAGE>

Period immediately preceding the Final Scheduled Distribution Date for the Class
B Notes, then the Servicer shall be obligated to purchase such Receivable
typically pursuant to Section 3.7.

          Section 3.3    Realization upon Receivables.  (a) On behalf of the
                         ----------------------------
Trust, the Servicer shall charge off a Receivable as a Liquidating Receivable in
accordance with its customary servicing procedures, generally no later than the
120th day of delinquency and, in no event, later than the 149th day of
delinquency, and shall use its best efforts to repossess and liquidate the
Financed Vehicle securing any Liquidating Receivable as soon as feasible after
default, in accordance with the standard of care required by Section 3.1,
typically after the Receivable is 90 days delinquent and, in no event, after the
Receivable is 100 days delinquent. In taking such action, the Servicer shall
follow such customary and usual practices and procedures as it shall deem
necessary or advisable in its servicing of motor vehicle retail installment sale
contracts, and as are otherwise consistent with the standard of care required
under Section 3.1, which shall include the exercise of any rights of recourse to
Dealers under the Dealer Agreements and Dealer Assignments (or rights to compel
repurchase against third Persons) and selling the Financed Vehicle at public or
private sale. The foregoing shall be subject to the provision that, in any case
in which a Financed Vehicle shall have suffered damage, the Servicer shall not
be obligated to 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
(which, in any event, shall not be unreasonable).

          (b)  In the event that the Servicer determines that, after it has
exhausted all customary and usual collection practices and procedures, including
efforts to repossess and liquidate a Financed Vehicle or recover a deficiency
balance related to a Liquidating Receivable, further collection efforts by it as
to such Receivable will not result in the realization of additional proceeds to
the Trust, and the Servicer believes in good faith that a sale is in the best
interests of the Trust, the Servicer may, on behalf of the Trust, sell the
Receivable to any Person not affiliated with the Servicer free and clear of the
rights of the Trust.  All proceeds of the sale of such Receivables hereunder
shall be deposited directly in or credited to the Collection Account.

          (c)  If the Servicer elects to commence a legal proceeding to enforce
a Dealer Agreement or Dealer Assignment, the act of commencement shall be deemed
to be an automatic assignment from the Trust to the Servicer of the rights of
recourse under such Dealer Agreement and Dealer Assignment. If, however, in any
enforcement suit or legal proceeding, it is held that the Servicer may not
enforce a Dealer Agreement or Dealer Assignment on the grounds that it is not a
real party in interest or a Person entitled to enforce the Dealer Agreement or
Dealer Assignment, the Trust, at the Servicer's expense, or the Seller, at the
Seller's expense, shall take such steps as the Servicer deems necessary to
enforce the Dealer Agreement or Dealer Assignment, including bringing suit in
its name or the names of the Securityholders.

          Section 3.4    Physical Damage Insurance.  (a) The Servicer shall
                         -------------------------
require that each Financed Vehicle be insured under an Insurance Policy naming
the Seller as loss payee. In the event that an Insurance Policy shall lapse or
shall be otherwise terminated, the Servicer, at its expense (and not at the
expense of the Trust), may procure a substitute policy of insurance, issued by
an insurer

                                      -36-
<PAGE>

selected by the Servicer, consistent with the standard of care required by
Section 3.1, and naming the Servicer or the Seller as loss payee. Any substitute
Insurance Policy procured hereunder shall provide coverage against physical
damage to the Financed Vehicle and such other risks as determined by the
Servicer and shall contain such other provisions (including deductibles and loss
payable clauses) as determined by the Servicer, in each case, consistent with
the standard of care required by Section 3.1. The cost of such Insurance Policy
may, to the extent consistent with applicable law and the terms of the
applicable Receivable, be added to the amount owing by an Obligor, but shall be
treated as a separate receivable not owned by the Trust for all purposes
hereunder and, in furtherance of the foregoing, shall not be included in the
definition of Receivable Balance or Aggregate Receivables Balance and
collections with respect thereto shall not be part of Available Interest or
Available Principal. In the event that any payment by an Obligor is insufficient
to pay the payment currently due on the Receivable and the amount due on the
receivable arising from the cost of such Insurance Policy, the payment shall be
divided pro rata based on the amount currently due on each.
        --- ----

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

          Section 3.5    Maintenance of Security Interests in Financed Vehicles.
                         ------------------------------------------------------
The Servicer, in accordance with the standard of care required under Section
3.1, shall take such steps as are necessary to maintain perfection of the
security interest created by each Receivable in the related Financed Vehicle for
the benefit of the Trust. 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 in the event the Servicer receives
notice of the relocation of a Financed Vehicle. If there has been an Event of
Servicing Termination (or the occurrence of an event specified in clause (iii)
or (iv) of Section 7.1(a) with respect to the Seller), upon the request of the
Trust, the Servicer, at its expense, shall promptly and duly execute and deliver
such documents and instruments, and take such other actions as may be necessary,
as evidenced by an Opinion of Counsel delivered to the Trust, to perfect the
Trust's interest in the Trust Property against all other Persons, including the
delivery of the Receivables and the Receivable Files to the Trustee, its agent,
or its designee, the endorsement and delivery of the Insurance Policies or the
notification of the insurers thereunder, the execution of transfer instruments,
and the endorsement to the Trustee 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 3.6    Covenants of the Servicer.  The Servicer makes the
                         -------------------------
following covenants upon which the Trust relies in accepting the Trust Property
in trust and in executing and delivering the Securities:

                                      -37-
<PAGE>

                         (i)       Security Interest to Remain in Force.  The
                                   ------------------------------------
     Financed Vehicle securing each Receivable will not be released from the
     security interest granted by the Receivable in whole or in part, except in
     the event of payment in full by the Obligor thereunder or disposition of a
     repossessed Financed Vehicle or except as may be required by an insurer in
     order to receive proceeds from insurance covering such Financed Vehicle or
     as otherwise contemplated herein.

                         (ii)      No Impairment.  The Servicer will not (nor
                                   -------------
     will it permit any subservicer to) impair in any material respect the
     rights of any Interested Party in the Receivables, the Dealer Agreements,
     the Dealer Assignments or the Insurance Policies or, subject to clause
     (iii) below, otherwise amend or alter the terms thereof if, as a result of
     such amendment or alteration, the interests of the Trust or any Interested
     Party hereunder would be materially adversely affected.

                         (iii)     Amendments.  The Servicer will not amend or
                                   ----------
     otherwise modify any Receivable (including, the grant of any extension
     thereunder), except in accordance with Section 3.2.

          Section 3.7    Purchases by the Servicer.  The Seller, the Servicer,
                         -------------------------
the Indenture Trustee or the Owner Trustee, as the case may be, shall inform the
other parties promptly, in writing, upon the discovery (which, in the case of
either Trustee, shall occur only upon the actual knowledge of an Authorized
Officer of such Trustee) of any breach by the Servicer of its covenants under
Section 3.6. Unless the breach shall have been cured by the last day of the
Collection Period which includes the 30th day after the date on which the
Servicer becomes aware of, or receives written notice of, such breach, the
Servicer shall purchase from the Trust the Receivable or Receivables, without
recourse, representation or warranty, other than that the Owner Trustee, on
behalf of the Trust materially and adversely affected thereby on the last day of
such Collection Period has not imposed any liens on the Receivable or
Receivables to be repurchased from the Trust; provided, however, that in the
                                              --------  -------
case of a breach of the covenant contained in Section 3.6(iii), the Servicer
shall be obligated to purchase the affected Receivable or Receivables on the
last day of the Collection Period during which the Servicer becomes aware of, or
receives written notice of, such breach (which in all cases shall be deemed to
have a material adverse effect on the Securityholders).  If the Servicer amends
or modifies a Receivable pursuant to Section 3.2(a), grants an Optional Payment
Deferral pursuant to Section 3.2(c) or a Credit Deferral pursuant to Section
3.2(b) and such amendment, modification or deferral causes the term of the
applicable Receivable to extend beyond the last day of the Collection Period
immediately preceding the Final Scheduled Distribution Date for the Class B
Notes, the Servicer shall be obligated to purchase the applicable Receivable on
the last day of the Collection Period during which the Servicer amends or
modifies such Receivable or grants such Optional Payment Deferral or Credit
Deferral.  In consideration of the purchase of a Receivable hereunder, the
Servicer shall remit the Repurchase Amount of such Receivable in the manner
specified in Section 4.3 on the related Deposit Date.  Except as provided in
Section 6.2, the sole remedy of the Trust, any Trustee, or the Securityholders
against the Servicer with respect to a breach pursuant to Section 3.6 shall be
to require the Servicer to purchase Receivables pursuant to this Section 3.7.

          Section 3.8    Servicing Compensation.  On each Distribution Date, the
                         ----------------------
Servicer shall be paid the Total Servicing Fee for such Distribution Date.  In
addition, the Servicer shall retain any late fees, prepayment charges or other
fees and charges (other than Deferral Fees)  collected during the Collection
Period (collectively, the "Supplemental Servicing Fee").  The Servicer shall be
                           --------------------------
required to pay all expenses incurred by it in connection with its activities
hereunder (including fees and expenses of either Trustee (and any custodian
appointed by such Trustee) and independent accountants, any subservicer, taxes
imposed on the Servicer or any subservicer, and expenses incurred in connection
with distributions and reports to the Trustees, the Rating Agencies and the
Securityholders) except expenses incurred in connection with realizing upon
Receivables under Section 3.3.   No transfer, sale, pledge or other disposition
of the Servicer's right to receive all or any portion of the Total Servicing Fee
shall be made, and any such attempted transfer, sale, pledge or other
disposition shall be void, unless such transfer is made to one or more successor
servicers in connection with the assumption by any such successor servicer of
the duties hereunder pursuant to Section 7.2 and all (and not a portion) of the
Total Servicing Fee is transferred to any such successor servicer.

          Section 3.9    Servicer's Certificate.  On or before the Determination
                         ----------------------
Date immediately preceding each Distribution Date, the Servicer shall deliver to
each Trustee a report of a Servicing Officer substantially in the form of

Certificate") containing all information necessary to make the distributions
-----------
pursuant to Section 4.5 and all information required to be provided to
Certificateholders and Noteholders pursuant to Section 4.7.  The Servicer also
shall separately identify (by account number of the Receivable as it appears in
the related Schedule of Receivables) in a written notice to the Trustees the
Receivables to be repurchased by the Seller or to be purchased by the Servicer,
as the case may be, on the related Deposit Date, and each Receivable which

Certificate, stating that (i) a review of the activities of the Servicer during
the preceding calendar year (or shorter period, in the case of the first such

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 year (or shorter period, in
the case of the first such certificate), 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.

          (b)  The Servicer shall deliver to the Trust, the Owner Trustee and
the Indenture Trustee, promptly upon having knowledge thereof, but in no event
later than five 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, an Event of Servicing Termination under
Section 7.1.

(or shorter period, in the case of the first such report) and that such
examination (i) included tests relating to automobile and light-duty truck loans
serviced for others and such other auditing procedures as such firm considered
necessary under the circumstances and (ii) except as described in such report,
disclosed no exceptions or errors in the records relating to automobile and
light-duty truck loans serviced for others that in such firm's opinion, requires
such firm to report. In the event such firm requires the Trust, the Owner
Trustee and the Indenture Trustee to agree to the procedures performed by such
firm, the Servicer shall direct the Trust, the Owner Trustee and the Indenture
Trustee in writing to so agree; it being understood and agreed that the Trust,
the Owner Trustee and the Indenture Trustee will deliver such letter of
agreement in conclusive reliance upon the written direction of the Servicer, and
the Trust, the Owner Trustee and the Indenture Trustee make no independent
inquiry or investigation as to, and shall have no obligation or liability in
respect of, the sufficiency, validity or correctness of such procedures.

                         -----------------------------------------------
Regarding Receivables. The Servicer shall provide the Trustees and the
---------------------
Securityholders with access to the Receivable Files (in the case of the
Securityholders, where the Securityholder 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 hours at the office of the Servicer. Nothing in this Section 3.12 shall
affect the obligation of the Servicer to observe any applicable law prohibiting
disclosure of information regarding the Obligors, and the failure of the
Servicer to provide access to information as a result of such obligation shall
not constitute a breach of this Section. The Servicer shall deliver a copy of
all reports or notices furnished and delivered pursuant to Sections 3.9, 3.10
and 3.11 to a Securityholder upon written request of such Securityholder. Any
Securityholder, by its acceptance of a Security, shall be deemed to have agreed
to keep any information obtained by it pursuant to this Section confidential,
except as may be required by applicable law.

          Section 3.13   Reports to the Commission.  The Servicer shall, on
                         -------------------------
behalf of the Trust, cause to be filed with the Commission any periodic reports

requested by such Rating Agency to monitor this transaction.

     Certificateholders, shall establish and maintain in the name of the Trust

     understood and agreed that Indenture Trustee shall not be liable for any

     with the Indenture Trustee. The Indenture Trustee shall possess all right,
     title and interest in all funds on deposit from time to time in the
     Accounts and in all proceeds thereof (other than income

                                      -41-

     benefit of all Securityholders. If, at any time, any of the Accounts ceases
     to be an Eligible Deposit Account, the Indenture Trustee (or the Servicer
     on its behalf) shall within 10 Business Days (or such longer period, not to
     exceed 30 calendar days, as to which each Rating Agency shall consent)
     establish a new Account as an Eligible Deposit Account and shall transfer

          thereto;

                         (B)       the Indenture Trustee shall maintain Control
          over each Account in which any Account Property that constitutes a
          Security Entitlement, an Uncertificated Security or a Federal Book-
          Entry Security is held; and

                         (C)       any Account Property that constitutes either
          a Security Certificate or any other Account Property that constitutes
          Physical Property and that is not a Security Entitlement shall be
          transferred to the Indenture Trustee or its nominee or custodian by

     Securityholders, shall establish and maintain in the name of the Indenture
     Trustee an Eligible Deposit Account (the "Reserve Account") to include
                                               ---------------
     money and other property deposited and held therein pursuant to this
     Section 4.1(c)(i), Section 4.5(b)(v) and Section 4.6.  On the Closing Date,
     the Seller shall deposit the Reserve Account Initial Deposit with respect
     to the Closing Date into the Reserve Account.  The Reserve Account shall be
     the property of the Trust subject to the rights of the Indenture Trustee in
     the Reserve Account Property.

                         (ii)      Funds on deposit in the Reserve Account
     shall be invested by the Indenture Trustee in Eligible Investments selected
     by the Servicer (as provided in writing signed by it); provided, however,
                                                            --------  -------
     it is understood and agreed that the Indenture Trustee shall

     Trustee be liable for the selection of Eligible Investments. The Indenture
     Trustee shall have no obligation to invest or reinvest any amounts held
     hereunder in the absence of written investment direction. All such Eligible
     Investments shall be held by the Indenture Trustee for the benefit of the
     Securityholders; provided that on each Distribution Date all interest and
                      --------
     other investment income (net of losses and investment expenses) on funds on
     deposit therein shall be withdrawn from the Reserve Account at the
     direction of the Servicer and shall be paid to the Seller. Funds on deposit
     in the Reserve Account shall be invested in Eligible Investments that will
     mature so that such funds will be available at the opening of business on
     the next following Deposit Date; provided, however, that to the extent
                                      --------  -------
     permitted by the Rating Agencies, funds on deposit in the Reserve Account
     may be invested in Eligible Investments that mature later than the next
     Deposit Date.

                         (iii)     The Reserve Account shall initially be
     established with the Indenture Trustee and shall be under the sole dominion
     and control of the Indenture Trustee. If, at any time, the Reserve Account
     ceases to be an Eligible Deposit Account, the Servicer 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

     respect of the Reserve Account:

                         (A)       any Account Property that is held in deposit
          accounts shall be held solely in an Eligible Deposit Account; and each

          custody and control of the Indenture Trustee and the Indenture Trustee
          shall have sole signature authority with respect thereto;

                         (B)       the Indenture Trustee shall maintain Control

          physical delivery to the Indenture Trustee or its nominee or custodian

Servicer shall have the Required Rating or (ii) (a) the Servicer shall have
obtained a letter of credit or surety bond (or similar form of performance
guaranty) from an entity with the Required Rating or otherwise acceptable to the
Rating Agencies in favor of the Trust for the benefit of the Securityholders,
providing that the Trust may demand payment (up to the amount then available
thereunder) in the event that the Servicer fails to make any payment or deposit
required hereunder (other than with respect to Advances) and (b) the Trust shall
have received written notice from each of the Rating Agencies (provided that
Moody's shall not be obligated to give any such notice) that the then
outstanding rating on the Notes would not be lowered or withdrawn as a result,
the Servicer may deposit the amounts referred to in subsection (a) above for any
Collection Period into the Collection Account not later than the close of
business on the related Deposit Date, for so long as the Servicer shall have the
Required Rating or such letter of credit, surety bond or similar form of
performance guaranty is in full force and effect, as the case may be; provided,
                                                                      --------
however, that (i) if an Event of Servicing Termination has occurred and is
-------
continuing, (ii) the Servicer has been terminated as such pursuant to Section
7.1 or (iii) the Servicer ceases to have the Required Rating (and the Servicer
has not obtained a letter of credit (or similar form of performance guaranty)
satisfying the conditions specified above), the Servicer shall deposit such
amounts (including any amounts then being held by the Servicer) into the
Collection Account as provided in Section 4.2(a).  Notwithstanding the
foregoing, the provisions of the proviso to the preceding sentence shall not be
applicable to a successor servicer solely by reason of the occurrence of an
event specified in clauses (i), (ii) and (iii) of such proviso with respect to
the outgoing Servicer. Prior to the occurrence of an event specified in clauses
(i), (ii) or (iii) in the preceding proviso, on a monthly basis, all Collections
shall be segregated by book-entry or similar form of identification on the
Servicer's books and records and identified as the property of the Trust.  The
Servicer shall promptly notify the Trust and the Indenture Trustee in writing if
it shall obtain or lose the Required Rating or the benefit of such letter of
credit, surety bond, or similar form of performance guaranty.

          (c)  Notwithstanding the provisions of subsections (a) and (b) hereof,
the Servicer may retain, or will be entitled to be reimbursed, from amounts
otherwise payable into, or on deposit in, the Collection Account with respect to
a Collection Period and the Receivables originated by it any amounts previously
deposited in the Collection Account but later determined to have resulted from
mistaken deposits or postings or checks returned for insufficient funds, in each
case, with respect to which the Servicer has not been previously reimbursed
hereunder.  The amount to be retained or reimbursed hereunder shall not be
included in Collections with respect to the related Distribution Date.

          (d)  In those cases where a subservicer is servicing a Receivable, the
Servicer shall cause the subservicer to remit to the Collection Account as soon
as practicable, but in no event later than the close of business (New York time)
on the second Business Day after receipt thereof by the subservicer (but subject
to the provisions of Section 4.2 (b) and the limitations contained in Section
4.2(c) of this Agreement) the amounts referred to in Section 4.2(a) in respect
of a Receivable being serviced by the subservicer.

          Section 4.3    Advances.  (a) On each Deposit Date, the Servicer may
                         --------
make a payment with respect to each Receivable serviced by it (other than a
Liquidating Receivable) equal to the excess, if any, of (i) the product of the
Receivable Balance of such Receivable as of the first day of the related
Collection Period and one twelfth of its Contract Rate (calculated on the basis
of a 360-day year comprised of twelve 30-day months) over (ii) Interest
Collections actually received by the Servicer as of the last day of such
Collection Period with respect to such Receivable (each such payment, an
"Advance").  With respect to each Receivable, the Advance shall increase
 -------
Outstanding Advances.  If such calculation results in a negative number, (i)
Outstanding Advances shall be reduced by such amount or (ii) if Outstanding
Advances is equal to zero, such amount shall be paid to the Servicer.  The
Servicer may elect not to make any Advance of due and unpaid interest with
respect to a Receivable to the extent that the Servicer, in its sole discretion,
determines that such Advance is not recoverable from subsequent payments on such
Receivable or from funds in the Reserve Account.  The Servicer shall not make
any advance with respect to principal of Receivables.

          (b)  The Servicer shall remit to Indenture Trustee for deposit to the
Collection Account the aggregate Advances on Receivables serviced by the
Servicer pursuant to Section 4.3(a). To the extent that the Servicer does not
make an Advance pursuant to Section 4.3(a) on the date required, the Servicer
shall so notify the Indenture Trustee in writing, and the Indenture Trustee
shall withdraw such amount (or, if determinable, such portion of such amount as
does not represent advances for delinquent interest) from the Reserve Account
and deposit such amount in the Collection Account.  The Servicer and the Seller
shall deposit or cause to be deposited in the Collection Account the aggregate
Repurchase Amount with respect to Purchased Receivables.  All such deposits
shall be made in immediately available funds on the Deposit Date.

          (c)  On each Deposit Date, prior to making any of the distributions
set forth in Section 4.5, the Servicer shall be reimbursed for all Outstanding
Advances with respect to prior Distribution Dates and, to the extent such funds
are insufficient, to the extent of the funds in the Reserve Account. If it is
acceptable to each Rating Agency without reduction in the rating of the Notes,
the Outstanding Advances at the option of the Servicer may be paid at or as soon
as possible after the beginning of the related Collection Period out of the
first collections of interest received on the Receivables for such Collection
Period.

          Section 4.4    Additional Deposits; Net Deposits.  The Servicer may
                         ---------------------------------
make the remittances to be made by it pursuant to Section 4.2 net of amounts to
be distributed to it pursuant to Section 4.5 (but subject to the priorities set
forth therein), for so long as (i) no Event of Servicing Termination has
occurred and is continuing and (ii) the Servicer has not been terminated as such
pursuant to Section 7.1 hereof; provided, however, that the Servicer shall
                                --------  -------
account for all of such amounts in the related Servicer's Certificate as if such
amounts were deposited and distributed

                                      -45-

separately; and provided further that, if an error is made by the Servicer in
                -------- -------
calculating the amount to be deposited or retained by it and a shortfall in the
amount deposited into the Collection Account results, the Servicer shall make a
payment of the deficiency to the Collection Account, immediately upon becoming
aware, or receiving notice from the Trust, of such shortfall.

damages, and liabilities, to the extent that such cost, expense, loss, claim,
damage, or liability arose out of, or was imposed upon, or incurred by, the
Trust, the Trustees or the Securityholders as a result of the willful
misfeasance, negligence, or bad faith of the Servicer in the performance of its
duties under the Basic Documents.

          (e)  The Servicer (other than the Indenture Trustee in its capacity as
successor Servicer pursuant to Section 7.2 hereof) shall indemnify, defend and

fees and expenses of counsel and expenses of litigation.  The indemnity
obligations of the Servicer hereunder

                                      -54-

with respect to obligations arising prior thereto, and any payment of the amount
owing under, or the Repurchase Amount with respect to, any Receivable and shall
survive the termination of the Trust or the earlier removal or resignation of
the Owner Trustee or the Indenture Trustee. If the Servicer shall have made any
indemnity payments pursuant to this Section 6.2 and the recipient thereafter
collects any of such amounts from others, the recipient shall, as soon as
practicable upon receipt thereof, repay such amounts to the Servicer, without
interest.

          Section 6.3    Merger or Consolidation of the Servicer.  Any
                         ---------------------------------------

assumption to all or substantially all of the business of the Servicer, where
the Servicer is not the surviving entity, which corporation or other entity
shall be an Eligible Servicer and shall execute an agreement of assumption to
perform every obligation of the Servicer under this Agreement, shall be the
successor to the Servicer under this Agreement (without relieving the outgoing
Servicer of its responsibilities hereunder, if it survives such merger,
conversion or consolidation) without any further act on the part of any of the
parties to this Agreement.  The Servicer shall promptly inform the Owner Trustee
and the Indenture Trustee and the Rating Agencies of any such merger,
conversion, consolidation or purchase and assumption where the Servicer is not
the surviving entity.

obligation to appear in, prosecute or defend any legal action that shall not be

liability; provided, however, that the Servicer may undertake, at its expense,
           --------  -------

Agreement and the rights and duties of the parties to this Agreement and the
interests of the Securityholders under this Agreement.

matters arising hereunder.

                         ----------------------
from its obligations and duties under this Agreement except upon a determination
that the performance of its duties is no longer permissible under applicable
law.  Any such determination permitting the resignation of the Servicer shall be
evidenced by an Opinion of Counsel (which counsel shall be outside counsel to
the Servicer) to such effect delivered to each Trustee.  No such resignation
shall become effective until the Indenture Trustee or a successor servicer shall
have assumed the responsibilities and obligations of the outgoing Servicer in
accordance with Section 7.2.

          Section 6.6    Servicer May Own Certificates.  The Servicer, and any
                         -----------------------------

such Notes then outstanding, by notice then given in writing to the Servicer
(and to the Indenture Trustee if given by the Noteholders), may terminate all of
the rights and obligations of the Servicer under this Agreement.  On or after
the receipt by the Servicer of such written notice, all authority and power of
the Servicer under this Agreement, whether with respect to the Securities or the
Trust Property or otherwise, shall pass to and be vested in the Indenture
Trustee or successor servicer appointed by the Indenture Trustee pursuant to

accomplish all other acts or things necessary or appropriate to effect the
purposes of such notice of termination, whether to complete the transfer and

connection with the transfer of servicing shall be paid by the outgoing Servicer
upon presentation of reasonable documentation of such costs and expenses.

          If no Notes are outstanding and the Indenture has been discharged in
accordance with its terms, and in each and every case and so long as an Event of
Servicing Termination shall not have been cured or waived, the Owner Trustee or
the holders of Certificates evidencing not less than a majority of the
Certificate Balance of such Certificates then outstanding, by notice then given
to the Servicer (and to the Owner Trustee if given by the Certificateholders),
may terminate all of the rights and obligations of the Servicer under this
Agreement.  On or after the receipt by the Servicer of such written notice, all
authority and power of the Servicer under this Agreement, whether with respect
to the Securities or the Trust Property or otherwise, shall pass to and be
vested in a successor servicer appointed by the Owner Trustee pursuant to

responsibilities and rights as Servicer under this Agreement, including the
transfer to such successor servicer for administration of all cash amounts that
are at the time held by the Servicer for deposit, shall have been deposited by
the Servicer in the Collection Account, or thereafter shall be received with
respect to a Receivable, all Receivable Files and all information or documents
that 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 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 upon
presentation of reasonable documentation of such costs and expenses.

          (b)  If any of the foregoing Events of Servicing Termination occur,
the Indenture Trustee shall have no obligation to notify Noteholders or any
other person and the Owner Trustee shall have no obligation to notify the
Certificateholders or any other Person of such occurrence prior to the
continuance of such event through the end of any cure period specified in
Section 7.1(a).

          Section 7.2    Trustee to Act; Appointment of Successor Servicer.
                         -------------------------------------------------
Upon the Servicer's resignation pursuant to Section 6.5, or upon the Servicer's
receipt of notice of termination as Servicer pursuant to Section 7.1, the
Indenture Trustee (or if no Notes are outstanding, a successor servicer
appointed by the Owner 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 responsibilities, duties and liabilities relating thereto placed on
the Servicer by the terms and provisions of this Agreement, except that such
Trustee, when acting as a successor servicer, shall not be obligated to make any
Advances hereunder or purchase Receivables pursuant to Section 3.7 unless the
obligation to purchase arose after the date of the notice of termination given
to the Servicer pursuant to Section 7.1 and relating to actions taken solely by
such Trustee as successor servicer, and such Trustee shall not be liable for any
acts or omissions of such terminated Servicer or for any breach by the
terminated Servicer of any of its representations or warranties contained herein
or in any related documents or agreements.  As compensation therefor, the
Indenture Trustee (or if no Notes are outstanding, a successor servicer
appointed by the Owner 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 notice of termination or
resignation had been given.  Notwithstanding the above, the Indenture Trustee
may, if it shall be unwilling or 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.  In connection with
such appointment, the Indenture Trustee may make such arrangements for the
compensation of such successor servicer out of payments on Receivables as it and
such successor shall agree, which, in no event, shall be greater than that
payable to First Security Bank, N.A. in its capacity as the Servicer hereunder.
Such Indenture Trustee (or if no Notes are outstanding, a successor servicer
appointed by the Owner Trustee) or such successor servicer shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession.  No Servicer shall resign or be relieved of its duties under
this Agreement until a newly appointed servicer shall have assumed the
responsibilities and obligations of the terminated Servicer under this
Agreement.  Notwithstanding anything herein or in the Indenture to the contrary,
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

                                      -58-
<PAGE>

the amount necessary to induce any successor Servicer to act as successor
Servicer under this Agreement and the transactions set forth or provided for
herein.

          Section 7.3    Effect of Servicing Transfer. (a) After the transfer of
                         ----------------------------
servicing hereunder, the Indenture Trustee (or, if no Notes are outstanding, a
successor servicer appointed by the Owner Trustee) or the successor servicer
shall notify 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 Sections 6.2 and 8.6 after the transfer of
servicing hereunder, the outgoing Servicer shall have no further obligations
with respect to the management, 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 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 and the outgoing Servicer shall continue to cooperate with the
successor servicer by providing information and in the enforcement of the Dealer
Agreements, the Dealer Assignments and the Insurance Policies.

          (c)  A transfer of servicing hereunder shall not affect the rights and
duties of the parties hereunder (including the obligations and indemnities of
the Seller pursuant to Sections 2.4, 5.1 and 5.2 or, with respect to obligations
and indemnities arising prior to, or concurrently with, a transfer of servicing
hereunder, the outgoing Servicer pursuant to Section 3.7, 6.1 and 6.2) other

terminated as Servicer hereunder.

          (d)  Any successor servicer shall provide the Seller 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. Nothing in this Section 7.3
shall affect the obligation of the successor servicer to observe any applicable
law prohibiting disclosure of information regarding the Obligors, and the
failure of the successor servicer to provide access to information as a result
of such obligation shall not constitute a breach of this Section 7.3.

its consequences, except an event resulting from the failure to make any
required deposits to, or payments from, any of the Accounts or the Reserve

covenants, restrictions or obligations of the Seller, the Servicer, the Owner
Trustee or the Indenture Trustee, or (v) to add, change or eliminate any other

exceptions stated therein, and (ii) the interest of the Trust in the
Receivables, the Dealer Agreements or the Dealer Assignments and in each case
the proceeds thereof against third parties, subject to certain exceptions stated
therein, and reciting the details of such filings or referring to prior Opinions

third party by reason of any action taken pursuant to any provision of this
Agreement.
