     SALE AND SERVICING AGREEMENT, dated as of November 1, 2005 (as from time
to time amended, supplemented or otherwise modified and in effect, this
"Agreement"), among USAA AUTO OWNER TRUST 2005-4 (the "Issuer"), a Delaware
statutory trust, USAA ACCEPTANCE, LLC, a Delaware limited liability company
(the "Depositor") and USAA FEDERAL SAVINGS BANK, a federally chartered savings
association, as seller of the Receivables to the Depositor (in such capacity,
the "Seller") and servicer (in such capacity, the "Servicer").

     WHEREAS, the Issuer desires to purchase a portfolio of receivables and
related property consisting of motor vehicle installment loan contracts
originated by the Seller in the ordinary course of its business;

     WHEREAS, the Seller is concurrently selling such portfolio of receivables
and related property to the Depositor pursuant to the Receivables Purchase
Agreement, and the Depositor is willing to sell such portfolio of receivables
and related property to the Issuer; and

     WHEREAS, the Servicer is willing to service such receivables on behalf of
the Issuer.

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained, and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto, intending to
be legally bound, agree as follows:

                                   ARTICLE I

                             DEFINITIONS AND USAGE

     Except as otherwise specified herein or as the context may otherwise
require, capitalized terms used but not otherwise defined herein are defined

applicable herein.

                                  ARTICLE II

                                TRUST PROPERTY

     SECTION 2.1 Conveyance of Trust Property; Intent of the Parties. In
consideration of the Issuer's delivery to, or upon the order of, the Depositor

Property, (ii) funds in the amount of the Yield Supplement Account Initial
Deposit and (iii) funds in the amount of the Reserve Initial Deposit. The

instrument related thereto. The Depositor and the Issuer intend that the sale,
transfer, assignment and conveyance of the Trust Property pursuant to this

purposes.


<PAGE>


     SECTION 2.2 Representations and Warranties of the Depositor regarding the
Receivables. The Depositor makes the following representations and warranties
with respect to the Receivables, on which the Issuer relies in purchasing the
Receivables and pledging the same to the Indenture Trustee. Such
representations and warranties speak as of the execution and delivery of this
Agreement and as of the Transfer Date, but shall survive the sale, transfer
and assignment of the Receivables by the Depositor to the Issuer and the
pledge of the Receivables by the Issuer to the Indenture Trustee pursuant to
the Indenture.

     (i)  Schedule of Receivables. The information set forth in Schedule A to
          this Agreement with respect to each Receivable is true and correct
          in all material respects, and no selection procedures adverse to the
          Securityholders have been used in selecting the Receivables from all
          receivables owned by the Seller which meet the selection criteria
          specified herein.

     (ii) No Sale or Transfer. No Receivable has been sold, transferred,
          assigned or pledged by the Depositor to any Person other than the
          Issuer.

    (iii) Good Title. Immediately prior to the transfer and assignment of the
          Receivables to the Issuer herein contemplated, the Depositor had
          good and marketable title to each Receivable free and clear of all
          Liens and rights of others; and, immediately upon the transfer
          thereof, the Issuer, has either (i) good and marketable title to
          each Receivable, free and clear of all of all Liens and rights of
          others, and the transfer has been perfected under applicable law or
          (ii) a first priority perfected security interest in each
          Receivable.

     (iv) Receivable Files. The Receivable Files shall be kept at one or more
          of the locations specified in Schedule B hereto.

     (v)  Characteristics of Receivables. Each Receivable (a) has been
          originated for the retail financing of a Financed Vehicle by an
          Obligor located in one of the States of the United States or the
          District of Columbia; (b) contains customary and enforceable
          provisions such that the rights and remedies of the holder thereof
          are adequate for realization against the collateral of the benefits
          of the security; and (c) provides for fully amortizing level
          scheduled monthly payments (provided that the payment in the last
          month in the life of the Receivable may be different from the level
          scheduled payment) and for accrual of interest at a fixed rate
          according to the simple interest method.

     (vi) Compliance with Law. Each Receivable and each sale of the related
          Financed Vehicle complied at the time it was originated or made, and
          complies on and after the Cut-off Date, in all material respects
          with all requirements of applicable federal, state, and local laws,
          and regulations thereunder, including usury laws, the Federal
          Truth-in-Lending Act, the Equal Credit Opportunity Act, the Fair
          Credit Reporting Act, the Federal Trade Commission Act, the
          Magnuson-Moss Warranty Act, Federal Reserve Board Regulations B and
          Z, state adaptations of the National Consumer Act and of the Uniform

<PAGE>


          other consumer credit, equal opportunity, and disclosure laws
          applicable to such Receivable and sale.

    (vii) Binding Obligation. Each Receivable constitutes the legal, valid,
          and binding payment obligation in writing of the Obligor,
          enforceable by the holder thereof in all material respects in
          accordance with its terms, subject, as to enforcement, to applicable
          bankruptcy, insolvency, reorganization, liquidation and other
          similar laws and equitable principles relating to or affecting the
          enforcement of creditors' rights.

   (viii) No Government Obligor. No Receivable is due from the United States
          of America or any state or from any agency, department,
          instrumentality or political subdivision of the United States of
          America or any state or local municipality and no Receivable is due
          from a business except to the extent that such receivable has a
          personal guaranty.

     (ix) Security Interest in Financed Vehicle. Immediately prior to the sale
          and assignment thereof to the Issuer as herein contemplated, each
          Receivable was secured by a validly perfected first priority
          security interest in the Financed Vehicle in favor of the Seller as
          secured party or all necessary and appropriate action with respect
          to such Receivable had been taken to perfect a first priority
          security interest in the related Financed Vehicle in favor of the
          Seller as secured party, which security interest is assignable and
          has been so assigned by the Seller to the Depositor and by the
          Depositor to the Issuer.

     (x)  Receivables in Force. No Receivable has been satisfied,
          subordinated, or rescinded, nor has any Financed Vehicle been
          released from the Lien granted by the related Receivable in whole or
          in part.

     (xi) No Waiver. No provision of a Receivable has been waived in such a
          manner that such Receivable fails either to meet all of the
          representations and warranties made by the Depositor herein with
          respect thereto pursuant to this Section 2.2.

    (xii) No Amendments. No Receivable has been amended except pursuant to
          instruments included in the Receivable Files and no such amendment
          has caused such Receivable either to fail to meet all of the
          representations and warranties made by the Depositor herein with
          respect thereto pursuant to this Section 2.2.

   (xiii) No Defenses. As of the Cut-off Date, there are no rights of
          rescission, setoff, counterclaim, or defense, and the Depositor has
          no knowledge of the same being asserted or threatened, with respect
          to any Receivable.

    (xiv) No Liens. As of the Cut-off Date, the Depositor has no knowledge of
          any Liens, claims that have been filed, including Liens for work,
          labor, materials or unpaid taxes relating to a Financed Vehicle,
          that would be Liens prior to, or equal or coordinate with, the Lien
          granted by the Receivable.

     (xv) No Default. Except for payment defaults continuing for a period of
          not more than thirty (30) days as of the Cut-off Date, the Depositor
          has no knowledge that a default, breach, violation, or event
          permitting acceleration under the terms of any Receivable exists;
          the Depositor has no knowledge that a continuing condition that with
          notice or lapse of time would constitute a default, breach,
          violation, or event permitting acceleration under the terms of any
          Receivable exists; and the Depositor has not waived any of the
          foregoing.

    (xvi) Insurance. Each Receivable requires that the Obligor thereunder
          obtain comprehensive and collision insurance covering the Financed
          Vehicle.

   (xvii) Lawful Assignment. No Receivable has been originated in, or is
          subject to the laws of, any jurisdiction under which the sale,
          transfer, and assignment of such Receivable under the Agreement is
          unlawful, void or voidable.

  (xviii) All Filings Made. No filings (other than UCC filings which have
          been made) or other actions are necessary in any jurisdiction to
          give the Issuer a first priority perfected security interest in the
          Receivables and to give the Indenture Trustee a first priority

     SECTION 2.3 Repurchase upon Breach. Each of the Depositor, the Servicer,
the Issuer and the Owner Trustee shall inform the other parties to this
Agreement promptly, in writing, upon the discovery by it of any breach of the
Depositor's representations and warranties pursuant to Section 2.2. Unless the
breach shall have been cured by the last day of the second Collection Period

Receivable pursuant to Section 3.3), in the manner specified in Section 4.5.
The sole remedy of the Issuer, the Owner Trustee, the Indenture Trustee, the
Noteholders or the Certificateholders with respect to a breach of the
Depositor's representations and warranties pursuant to Section 2.2 shall be to
require the Depositor to repurchase such Receivables pursuant to this Section
2.3. The obligation of the Depositor to repurchase under this Section 2.3
shall not be solely dependent upon the actual knowledge of the Depositor of
any breached representation or warranty. 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 2.3 or the eligibility of any Receivable
for purposes of this Agreement. Notwithstanding anything herein to the
contrary, the Depositor shall only be obligated to pay such Purchase Amount
and repurchase the related Receivable to the extent it receives the Purchase
Amount from the Seller pursuant to Section 7.02 of the Receivables Purchase
Agreement.

     SECTION 2.4 Custody of Receivable Files. To assure uniform quality in
servicing the Receivables and to reduce administrative costs, the Issuer, upon

Servicer, and the Servicer hereby accepts such appointment, to act as the
agent of the Issuer and the Indenture Trustee as custodian of the


                                      5
<PAGE>


following documents or instruments, which are hereby constructively delivered
to the Indenture Trustee, as pledgee of the Issuer pursuant to the Indenture,
with respect to each Receivable:

          (i) The original executed Receivable or, if no such original exists,
     a copy thereof.

          (ii) The original credit application fully executed by the Obligor
     or a photocopy thereof or a record thereof on a computer file, diskette
     or on microfiche.

          (iii) The notice of recorded Lien or such documents that the
     Servicer or the Depositor shall keep on file, in accordance with its
     customary procedures, evidencing the first priority perfected security
     interest of the Seller in the Financed Vehicle.

          (iv) Any and all other documents (including any computer file,
     diskette or microfiche) that the Servicer or the Seller shall keep on
     file, in accordance with its customary procedures, relating to a
     Receivable, an Obligor (to the extent relating to a Receivable), or a
     Financed Vehicle.

     The Servicer acknowledges that it holds the documents and instruments
relating to the Receivables for the benefit of the Issuer and the Indenture
Trustee. The Issuer and the Indenture Trustee shall have no responsibility to
monitor the Servicer's performance as custodian and shall have no liability in
connection with the Servicer's performance of such duties hereunder.

benefit of the Issuer and the Indenture Trustee and shall maintain such
accurate and complete accounts, records and computer systems pertaining to
each Receivable File as shall enable the Servicer and the Issuer to comply
with the terms and conditions of this Agreement, and the Indenture Trustee to
comply with the terms and conditions of the Indenture. In performing its
duties as custodian, the Servicer shall act with reasonable care, using that
degree of skill and attention that the Servicer exercises with respect to the
receivable files relating to all comparable automotive receivables that the
Servicer services for itself or others. The Servicer shall conduct, or cause
to be conducted, periodic audits of the Receivable Files held by it under this
Agreement and of the related accounts, records and computer systems, in such a
manner as shall enable the Issuer or the Indenture Trustee to identify all
Receivables Files and such related accounts, records and computer systems and
verify the accuracy of the Servicer's record keeping. The Servicer shall
promptly report to the Issuer and the Indenture Trustee any failure on its
part to hold the Receivable Files and maintain its accounts, records, and
computer systems as herein provided and shall 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 Issuer, the Owner Trustee or the
Indenture Trustee of the Receivable Files.

     (b) Maintenance of and Access to Records. The Servicer shall maintain
each Receivable File at its offices specified in Schedule B to this Agreement,
or at such other office as shall be specified to the Issuer and the Indenture
Trustee by 30 days' prior written notice. The Servicer shall make available to
the Issuer and the Indenture Trustee or their duly authorized representatives,
attorneys, or auditors, the Receivable Files and the related accounts, records
and


                                      6
<PAGE>


computer systems maintained by the Servicer during normal business hours as
the Issuer or the Indenture Trustee shall reasonably request, which does not
unreasonably interfere with the Servicer's normal operations.

     (c) Release of Documents. Upon written instructions from the Indenture
Trustee, the Servicer shall release or cause to be released any document in
the Receivable Files to the Indenture Trustee, the Indenture Trustee's agent
or the Indenture Trustee's designee, as the case may be, at such place or
places as the Indenture Trustee may reasonably designate, as soon as is
reasonably practicable, to the extent it does not unreasonably interfere with
the Servicer's normal operations. The Servicer shall not be responsible for
any loss occasioned by the failure of the Indenture Trustee or its agent or
designee to return any document or any delay in doing so.

     SECTION 2.6 Instructions; Authority to Act. All instructions from the
Indenture Trustee shall be in writing and signed by an Authorized Officer of
the Indenture Trustee, and the Servicer shall be deemed to have received
proper instructions with respect to the Receivable Files upon its receipt of
such written instructions.

     SECTION 2.7 Custodian's Indemnification. The Servicer, as custodian,
shall indemnify the Issuer, the Owner Trustee and the Indenture Trustee for
any and all liabilities, obligations, losses, compensatory damages, payments,
costs, or expenses of any kind whatsoever that may be imposed on, incurred, or
asserted against the Issuer, the Owner Trustee or the Indenture Trustee as the
result of any improper act or omission in any way relating to the maintenance
and custody by the Servicer as custodian of the Receivable Files; provided,
however, that the Servicer shall not be liable (i) to the Issuer for any
portion of any such amount resulting from the willful misfeasance, bad faith,
or negligence of the Indenture Trustee, the Owner Trustee or the Issuer, (ii)
to the Owner Trustee for any portion of any such amount resulting from the
willful misfeasance, bad faith, or negligence of the Indenture Trustee, the
Owner Trustee or the Issuer and (iii) to the Indenture Trustee for any portion
of any such amount resulting from the willful misfeasance, bad faith, or
negligence of the Indenture Trustee, the Owner Trustee or the Issuer.

     SECTION 2.8 Effective Period and Termination. The Servicer's appointment
as custodian shall become effective as of the Cut-off Date and shall continue
in full force and effect until terminated pursuant to this Section 2.8. If the
Bank shall resign as Servicer in accordance with the provisions of this
Agreement or if all of the rights and obligations of the Servicer shall have
been terminated under Section 7.1, the appointment of the Servicer as
custodian hereunder may be terminated by the Indenture Trustee, or by the
holders of Notes evidencing not less than a majority of the principal amount
of the Notes Outstanding (or if no Notes are Outstanding, by holders of
Certificates evidencing not less than a majority of the Certificate Balance),
in the same manner as the Indenture Trustee or such Securityholders may
terminate the rights and obligations of the Servicer under Section 7.1. As
soon as practicable after any termination of such appointment, the Servicer
shall deliver to the Indenture Trustee or the Indenture Trustee's agent the
Receivable Files and the related accounts and records maintained by the
Servicer at such place or places as the Indenture Trustee may reasonably
designate.

                                  ARTICLE III

        ADMINISTRATION AND SERVICING OF RECEIVABLES AND TRUST PROPERTY

     SECTION 3.1 Duties of Servicer. The Servicer shall manage, service,
administer and make collections on the Receivables with reasonable care, using
that degree of skill and attention that the Servicer exercises with respect to
all comparable new or used automobile and light-duty truck receivables that it
services for itself. The Servicer's duties shall include collection and
posting of all payments, responding to inquiries of Obligors on such
Receivables, investigating delinquencies, sending payment coupons to Obligors,
reporting tax information to Obligors, accounting for collections, furnishing
monthly and annual statements to the Owner Trustee and the Indenture Trustee
with respect to distributions, making Advances pursuant to Section 4.4,
preparing (or causing to be prepared) the tax returns of the Trust in
accordance with Section 5.6 of the Trust Agreement and, if requested to do so,
providing the certifications required, pursuant to Section 5.1(b) hereof. The
Servicer shall follow its customary standards, policies and procedures in
performing its duties 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 Issuer, the Owner Trustee, the Indenture
Trustee, the Noteholders, the Certificateholders, or any of them, any and all
instruments of satisfaction or cancellation, or partial or full release or
discharge, and all other comparable instruments, with respect to such
Receivables or to the Financed Vehicles securing such Receivables. If the
Servicer shall commence a legal proceeding to enforce a Receivable, the Issuer
(in the case of a Receivable other than a Purchased Receivable) shall
thereupon be deemed to have automatically assigned, solely for the purpose of
collection, such Receivable to the Servicer. 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 the Receivable, the Issuer shall, at the Servicer's
expense and direction, take steps to enforce the Receivable, including
bringing suit in its name or the names of the Indenture Trustee, the
Noteholders, the Certificateholders, or any of them. The Issuer shall furnish
the Servicer with any powers of attorney and other documents reasonably
necessary or appropriate to enable the Servicer to carry out its servicing and
administrative duties hereunder.

     SECTION 3.2 Collection 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 shall
follow such collection procedures as it follows with respect to all comparable
new or used automobile and light-duty truck receivables that it services for
itself. The Servicer shall not change the amount of or reschedule the due date
of any scheduled payment of a Receivable to a date more than 30 days from the
original due date of such scheduled payment, change the annual percentage rate
of or extend any Receivable or change any material term of a Receivable,
except as provided by the terms of the Receivable or of this Agreement or as
required by law or court order; provided, however, that the Servicer may
extend any Receivable that is in default or with respect to which default is
reasonably foreseeable and that would be acceptable to the Servicer with
respect to comparable new or used automobile and light-duty truck receivables
that it services for itself if (a) the amount on deposit in the Reserve
Account is greater than zero at the time of the extension, (b) the total
credit-related extensions granted on the Receivable will not exceed four
months in the aggregate,


                                      8
<PAGE>


(c) the total number of credit-related extensions granted on the Receivable
will not exceed two, and (d) the maturity of such Receivable will not be
extended beyond January 8, 2012. If, as a result of inadvertently rescheduling
or extending payments, such rescheduling or extension breaches any of the
terms of the proviso to the preceding sentence, then the Servicer shall be
obligated to purchase such Receivable pursuant to Section 3.7. For the purpose
of such purchases pursuant to Section 3.7, notice shall be deemed to have been
received by the Servicer at such time as shall make purchase mandatory as of
the last day of the Collection Period during which the discovery of such
breach occurred.

     Notwithstanding anything to the contrary herein, the Servicer may
implement programs that grant payment extensions in respect of receivables
that are not delinquent. Any such program shall be implemented with the
approval of the senior officer's credit committee of the Servicer in
accordance with the Servicer's general lending and policy guidelines. Any such
payment extension may extend the maturity of the applicable receivable beyond
its original term to maturity. Notwithstanding anything to the contrary
herein, the Servicer may also reduce the interest rate on Receivables affected
by the application of the Servicemembers Civil Relief Act to a rate that is
lower than the maximum rate prescribed by the Servicemembers Civil Relief Act
and may readjust the payment schedule for any Receivable that is affected by
the application of the Servicemembers Civil Relief Act until the maturity of
the receivable.

     SECTION 3.3 Realization Upon Receivables. On behalf of the Issuer, the
Servicer shall use reasonable efforts, consistent with its customary
standards, policies and procedures, to repossess or otherwise convert the
ownership of the Financed Vehicle securing any Receivable as to which the
Servicer shall have determined to be a Defaulted Receivable or otherwise (and
shall specify any such Defaulted Receivable to the Indenture Trustee no later
than the Determination Date following the Collection Period in which the
Servicer shall have made such determination). The Servicer shall follow such
customary standards, policies and procedures as it shall deem necessary or
advisable in its servicing of comparable receivables, which may include
selling the Financed Vehicle at public or private sale. The Servicer shall be
entitled to recover from proceeds all reasonable expenses incurred by it in
the course of converting the Financed Vehicle into cash proceeds. The
Liquidation Proceeds (net of such expenses) realized in connection with any
such action with respect to a Receivable shall be deposited by the Servicer in
the Collection Account in the manner specified in Section 4.2 and shall be
applied to reduce (or to satisfy, as the case may be) the Purchase Amount of
the Receivable, if such Receivable is to be repurchased by the Depositor
pursuant to Section 2.3, or is to be purchased by the Servicer pursuant to
Section 3.7. The foregoing shall be subject to the provision that, in any case
in which the Financed Vehicle shall have suffered damage, the Servicer shall
not be required 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 by an amount greater than the amount of such expenses.

     SECTION 3.4 Allocations of Collections. If an Obligor is obligated under
one or more Receivables and also under one or more other assets owned by the
Bank or assigned by the Bank to third parties, then any payment on any such
asset received from or on behalf of such Obligor shall, if identified as being
made with respect to a particular item or asset, be applied to such


                                      9
<PAGE>


item, and otherwise shall be allocated by the Bank in accordance with its
customary standards, policies and procedures.

     SECTION 3.5 Maintenance of Security Interests in Financed Vehicles. The
Servicer shall, in accordance with its customary procedures, take such steps
as are necessary to maintain perfection of the security interest created by
each Receivable in the related Financed Vehicle. The Issuer hereby authorizes
the Servicer to take such steps as are necessary to re-perfect such security
interest on behalf of the Issuer and the Indenture Trustee in the event of the
relocation of a Financed Vehicle or for any other reason, in either case, when
the Servicer has knowledge of the need for such re-perfection. In the event
that the assignment of a Receivable to the Issuer is insufficient, without a
notation on the related Financed Vehicle's certificate of title, or without
fulfilling any additional administrative requirements under the laws of the
state in which the Financed Vehicle is located, to transfer to the Issuer a
perfected security interest in the related Financed Vehicle, the Servicer
hereby agrees that the Servicer's listing as the secured party on the
certificate of title is deemed to be in its capacity as agent of the Issuer
and the Indenture Trustee and further agrees to hold such certificate of title
as the agent and custodian of the Issuer and the Indenture Trustee; provided
that the Servicer shall not, nor shall the Issuer or the Indenture Trustee
have the right to require that the Servicer, make any such notation on the
related Financed Vehicles' certificate of title or fulfill any such additional
administrative requirement of the laws of the state in which a Financed
Vehicle is located.

     SECTION 3.6 Covenants of Servicer. The Servicer shall not (i) release the
Financed Vehicle securing each such Receivable from the security interest
granted by such Receivable in whole or in part except in the event of payment
in full by or on behalf of the Obligor thereunder, (ii) impair the rights of
the Trust or the Indenture Trustee in the Receivables, or (iii) increase the
number of payments under a Receivable, increase the Amount Financed under a
Receivable or extend or forgive payments on a Receivable, except as provided
in Section 3.2. In the event that at the end of the scheduled term of any
Receivable, the outstanding principal amount thereof is such that the final
payment to be made by the related Obligor is larger than the regularly
scheduled payment of principal and interest made by such Obligor, the Servicer
may permit such Obligor to pay such remaining principal amount in more than
one payment of principal and interest; provided that the last such payment
shall be due on or prior to the Collection Period immediately preceding the
Class B Final Scheduled Payment Date.

     SECTION 3.7 Purchase of Receivables Upon Breach. (a) The Servicer, the
Depositor or the Owner Trustee, as the case may be, promptly shall inform the
other parties to this Agreement, in writing, upon the discovery of any breach
pursuant to Section 3.2, 3.5 or 3.6. Unless the breach shall have been cured
by the last day of the second Collection Period following such discovery (or,
at the Servicer's election, the last day of the first following Collection
Period), the Servicer shall purchase any Receivable materially and adversely
affected by such breach as determined by the Indenture Trustee (which shall
include any Receivable as to which a breach of Section 3.6 has occurred) at
the Purchase Amount (less any Liquidation Proceeds deposited, or to be
deposited, in the Collection Account with respect to such Receivable pursuant
to Section 3.3). In consideration of the purchase of such Receivable, the
Servicer shall remit the Purchase Amount in the manner specified in Section
4.5. For purposes of this Section 3.7, the Purchase Amount shall consist in
part of a release by the Servicer of all


                                      10
<PAGE>


rights of reimbursement with respect to Outstanding Advances on the
Receivable. The sole remedy of the Issuer, the Owner Trustee, the Indenture
Trustee, the Noteholders or the Certificateholders with respect to a breach
pursuant to Section 3.2, 3.5 or 3.6 shall be to require the Servicer to
purchase Receivables pursuant to this Section 3.7.

     (b) With respect to all Receivables purchased pursuant to this Section
3.7, the Issuer shall assign to the Servicer or the Depositor, as applicable,
without recourse, representation or warranty, all of the Issuer's right, title
and interest in and to such Receivables and all security and documents
relating thereto.

     SECTION 3.8 Servicer Fees. The Servicer shall be entitled to any interest
earned on the amounts deposited in the Collection Account during each
Collection Period plus all late fees, prepayment charges and other
administrative fees and expenses or similar charges, if any, allowed by
applicable law and the terms of the Receivables during each Collection Period
(the "Supplemental Servicing Fee"). The Servicer also shall be entitled to the
Servicing Fee, as provided herein.

     SECTION 3.9 Servicer's Certificate. On or prior to the Determination Date
for each Payment Date, the Servicer shall deliver to the Depositor, the Owner
Trustee, each Note Paying Agent and Certificate Paying Agent, the Indenture
Trustee and the Seller, with a copy to the Rating Agencies, a Servicer's
Certificate containing all information (including all specific dollar amounts)
necessary to make the transfers and distributions pursuant to Sections 4.3,
4.4, 4.5, 4.6, 4.7 and 4.8 hereof, and Section 8.2 of the Indenture for the
Collection Period preceding the date of such Servicer's Certificate, together
with the written statements to be furnished by the Owner Trustee to
Certificateholders pursuant to Section 4.10 hereof and by the Indenture
Trustee to the Noteholders pursuant to Section 4.10 hereof and Section 6.6 of
the Indenture. Receivables purchased or to be purchased by the Servicer or the
Depositor shall be identified by the Servicer by the Seller's account number
with respect to such Receivable (as specified in the Schedule of Receivables).

     SECTION 3.10 Annual Statement as to Compliance; Notice of Event of
Servicing Termination. (a) The Servicer shall deliver to the Owner Trustee,
the Indenture Trustee and each Rating Agency on or before March 31 of each
year beginning March 31, 2006, an Officer's Certificate, with respect to the
preceding 12-month period (or such shorter period in the case of the first
such certificate), stating that (i) a review of the activities of the Servicer
during the preceding 12-month period (or such shorter period in the case of
the first such certificate) and of its performance under this Agreement has
been made under such officer's supervision and (ii) to the best of such
officer's knowledge, based on such review, the Servicer has fulfilled all its
obligations under this Agreement throughout 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 Officer's Certificate and the report referred to in Section 3.11 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 telephone request of the Owner
Trustee, the Indenture Trustee shall promptly furnish the Owner Trustee a list
of Noteholders as of the date specified by the Owner Trustee.


                                      11
<PAGE>


Notwithstanding the foregoing in this Section 3.10(a), the Servicer, in its
sole discretion, may deliver, in addition to or in lieu of the Officer's
Certificate referred to above in this Section 3.10(a), the report on
compliance with servicing criteria that would be required to be filed in
respect of the Trust under the Exchange Act if periodic reports under Section
15(d) of the Exchange Act, or any successor provision thereto, were required
to be filed in respect of the Trust.

     (b) The Servicer shall deliver to the Owner Trustee, the Indenture
Trustee and each Rating Agency promptly after having obtained knowledge
thereof, but in no event later than five (5) Business Days thereafter, written
notice in an Officer's Certificate of any event which with the giving of
notice or lapse of time, or both, would become an Event of Servicing
Termination under Section 7.1. The Seller shall deliver to the Owner Trustee,
the Indenture Trustee and each Rating Agency promptly after having obtained
knowledge thereof, but in no event later than five (5) Business Days
thereafter, written notice in an Officer's Certificate of any event which with
the giving of notice or lapse of time, or both, would become an Event of
Servicing Termination under clause (a)(ii) of Section 7.1.

     SECTION 3.11 Annual Independent Certified Public Accountant's Report. The
Servicer shall cause a firm of independent certified public accountants, who
may also render other services to the Servicer, the Seller or the Depositor,
to deliver to the Owner Trustee and the Indenture Trustee on or before March
31 of each year beginning March 31, 2006 with respect to the prior calendar
year (or such shorter period in the case of the first such report) a report
addressed to the board of directors of the Servicer and to the Owner Trustee
and the Indenture Trustee, to the effect that such firm has examined the
automobile and light-duty truck receivable servicing functions of the Servicer
for such period, including the Servicer's procedures and records relating to
servicing of the Receivables under this Agreement and that, on the basis of
such examination, such firm is of the opinion that such servicing has been
conducted during such period in compliance with this Agreement except for (a)
such exceptions as such firm believes to be immaterial and (b) such other
exceptions as shall be set forth in such firm's report. In addition, such
report shall state that such firm has compared the mathematical calculations
of each amount set forth in the Servicer's Certificates forwarded by the
Servicer pursuant to Section 3.9 during the period covered by such report
(which shall be the preceding calendar year or such shorter period in the case
of the first such report) with the Servicer's computer reports which were the
source of such amounts and that on the basis of such comparison, such firm is
of the opinion that such amounts are in agreement, except for such exceptions
as such firm believes to be immaterial and such other exceptions as shall be
set forth in such statement. In addition, such report shall set forth the
procedures performed in conjunction with the examination and shall contain a
statement of such firm as to the accuracy of the amounts set forth in the
Servicer's Certificates delivered pursuant to Section 3.9 in such period.
Notwithstanding the foregoing in this Section 3.11, the Servicer, in its sole
discretion, may cause to be delivered, in lieu of the report referred to above
in this Section 3.11, the attestation report of a registered public accounting
firm that would be required to be filed in respect of the Trust under the
Exchange Act if periodic reports under Section 15(d) of the Exchange Act, or
any successor provision thereto, were required to be filed in respect of the
Trust.


                                      12
<PAGE>


     The report or attestation report, as applicable, will also indicate that
the firm is independent of the Servicer within the meaning of the Code of
Professional Ethics of the American Institute of Certified Public Accountants.

     SECTION 3.12 Access to Certain Documentation and Information Regarding
Receivables. The Servicer shall provide to the Certificateholders, the
Indenture Trustee and the Noteholders access to the Receivable Files in such
cases where the Certificateholders, the Indenture Trustee or the Noteholders
shall be required by applicable statutes or regulations to review such
documentation. Access shall be afforded without charge, but only upon
reasonable request and during the normal business hours at the respective
offices 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 3.12.

     SECTION 3.13 Servicer Expenses. The Servicer shall be required to pay all
expenses incurred by it in connection with its activities hereunder, including
fees, expenses (including counsel fees and expenses) and disbursements of the

imposed on the Servicer and expenses incurred in connection with distributions
and reports to Noteholders and Certificateholders.

     SECTION 3.14 Insurance. The Servicer, in accordance with its customary
servicing procedures and underwriting standards, shall require that each
Obligor shall have obtained and shall maintain comprehensive and collision
insurance covering the related Financed Vehicle as of the execution of the

to comparable new or used automobile and light-duty truck receivables that it
services for itself or others.

         DISTRIBUTIONS; RESERVE ACCOUNT; STATEMENTS TO NOTEHOLDERS AND
                              CERTIFICATEHOLDERS

     SECTION 4.1 Accounts. (a) The Servicer shall, prior to the Closing Date,
cause to be established and maintained an Eligible Deposit Account in the name
"JPMorgan Chase Bank, National Association, as Indenture Trustee, as secured
party from USAA Auto Owner Trust 2005-4", initially at the corporate trust
department of the Indenture Trustee, which shall be designated as the
"Collection Account". The Collection Account shall be under the sole dominion
and control of the Indenture Trustee; provided, that the Servicer may make
deposits to and direct the Indenture Trustee in writing to make withdrawals
from the Collection Account in accordance with the terms of the Basic
Documents. The Collection Account will be established and maintained pursuant
to an account agreement which specifies New York law as the governing law. In
addition, the Collection Account shall be established and maintained at an
institution which agrees in writing that for so long as the Notes are
outstanding it will comply with entitlement orders (as defined in Article 8 of
the UCC) originated by the Indenture Trustee


                                      13
<PAGE>


without further consent of the Issuer. All monies deposited from time to time
in the Collection Account shall be held by the Indenture Trustee as secured
party for the benefit of the Noteholders and, after payment in full of the
Notes, as agent of the Issuer and as part of the Trust Property. All deposits
to and withdrawals from the Collection Account shall be made only upon the
terms and conditions of the Basic Documents.

     If the Servicer is required to remit collections 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 specified Permitted Investments that
mature not later than the Business Day immediately prior to the Payment Date
for the Collection Period to which such amounts relate and such Permitted
Investments shall be held to maturity. All interest and other income (net of
losses and investment expenses) on funds on deposit in the Collection Account
shall be withdrawn from the Collection Account at the written direction of the
Servicer and shall be paid to the Servicer. The Indenture Trustee shall not be
liable for investment losses in Permitted Investments made in accordance with
directions from the Servicer. In the event that the Collection Account is no
longer to be maintained at the corporate trust department of the Indenture
Trustee, the Servicer shall, with the Indenture Trustee's or Issuer's
assistance as necessary, cause an Eligible Deposit Account to be established
as the Collection Account within ten (10) Business Days (or such longer period
not to exceed thirty (30) calendar days as to which each Rating Agency may
consent) and give written notice of the location and account number of such
account to the Indenture Trustee.

     (b) The Servicer shall, prior to the Closing Date, establish and maintain
an administrative subaccount within the Collection Account at the bank or
trust company then maintaining the Collection Account, which subaccount shall
be designated as the "Principal Distribution Account". The Principal
Distribution Account is established and maintained solely for administrative
purposes.

     (c) The Servicer shall, prior to the Closing Date, cause an Eligible
Deposit Account to be established and maintained, in the name "USAA Auto Owner
Trust 2005-4 Certificate Distribution Account", initially at the corporate
trust department of the Owner Trustee, which shall be designated as the
"Certificate Distribution Account". The Certificate Distribution Account shall
be under the sole dominion and control of the Owner Trustee. All monies
deposited from time to time in the Certificate Distribution 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 the Basic Documents.
In the event that the Certificate Distribution Account is no longer to be
maintained at the corporate trust department of the Owner Trustee, the
Servicer shall cause an Eligible Deposit Account to be established as the
Certificate Distribution Account within ten (10) Business Days (or such longer
period not to exceed thirty (30) calendar days as to which each Rating Agency
may consent) and give written notice of the location and account number of
such account to the Owner Trustee. The Certificate Distribution Account will
be established and maintained pursuant to an account agreement which specifies
New York law as the governing law.

     SECTION 4.2 Collections. The Servicer shall remit to the Collection
Account within two (2) Business Days of the receipt thereof (i) all payments
by or on behalf of the Obligors (but excluding Purchased Receivables) and (ii)
all Liquidation Proceeds, both as collected during the Collection Period;
provided that the Bank, so long as it is acting as the Servicer and no Event
of Servicing Termination has occurred and is continuing, may make remittances
of collections on a less frequent basis than that specified in the immediately
preceding sentence. It is understood that such less frequent remittances may
be made only on the specific terms and conditions set forth below in this
Section 4.2 and only for so long as such terms and conditions are fulfilled.
Accordingly, notwithstanding the provisions of the first sentence of this
Section 4.2, the Servicer shall remit collections received during a Collection
Period to the Collection Account in immediately available funds on the
Business Day preceding the related Payment Date but only for so long as the
Monthly Remittance Condition is satisfied. The Owner Trustee or the Indenture
Trustee shall not be deemed to have knowledge of any event or circumstance in
the definition of Monthly Remittance Condition that would require remittance
by the Servicer to the Collection Account within two (2) Business Days of
receipt as aforesaid unless the Owner Trustee or the Indenture Trustee has
received written notice of such event or circumstance from the Seller or the
Servicer in an Officer's Certificate or from the holders of Notes evidencing
not less than 25% of the principal amount of the Notes Outstanding or from the
Certificateholders of Certificates evidencing not less than 25% of the

circumstance. For purposes of this Article IV the phrase "payments by or on
behalf of Obligors" shall mean payments made by Persons other than the

     SECTION 4.3 Application of Collections. For the purposes of this
Agreement, as of the close of business on the last day of each Collection
Period, all collections for the Collection Period with respect to each
Receivable (other than a Purchased Receivable) shall be applied by the
Servicer first to the amount of interest accrued on such Receivable to the
date of receipt, then to reduce the scheduled principal amount outstanding on
the Receivable to the extent of the remaining scheduled payment and then to
any outstanding fees under the terms of the Receivable. Amounts paid by the
Depositor, the Seller or the Servicer in respect of Purchased Receivables
shall be allocated first to any interest accrued on the related Receivable and
then to the Principal Balance of the related Receivable.

     SECTION 4.4 Advances. (a) As of each Determination Date, the Servicer
shall make a payment with respect to each Receivable (other than a Defaulted
Receivable) equal to the excess, if any, of (x) the product of the Principal
Balance of such Receivable as of the first day of the related Collection
Period and one-twelfth of the Annual Percentage Rate (as adjusted downward, as
the case may be, in accordance with the Servicemembers Civil Relief Act or
pursuant to Section 3.2) on such Receivable (calculated on the basis of a
360-day year of twelve 30-day months), over (y) the interest actually received
by the Servicer with respect to such Receivable from the Obligor or from
payment of the Purchase Amount during or with respect to such Collection
Period. The Servicer shall deposit all such Advances into the Collection
Account in immediately available funds no later than, 11:00 a.m. New York City
time, on the Determination Date. Notwithstanding the foregoing, the Servicer
may elect not to make any Advance with respect to a Receivable to the extent
that the Servicer, in its sole discretion, shall determine that such Advance
is not recoverable from subsequent payments on such Receivable or from


                                      15

withdrawals from the Reserve Account. To the extent that the amount set forth
in clause (y) above with respect to a Receivable is greater than the amount
set forth in clause (x) above with respect thereto, such excess amount shall
be distributed to the Servicer pursuant to Section 4.6(b). In addition, in the
event that a Receivable becomes a Defaulted Receivable, Outstanding Advances
in respect of that Receivable shall be reimbursed to the extent of interest
Collections with respect to such Receivable and, if such amounts are
insufficient, from amounts on deposit in the Reserve Account, and if such
amounts are not sufficient, from amounts on deposit in the Collection Account.
The Servicer shall not make any advance with respect to principal of
Receivables.

     (b) The Servicer shall deposit in the Collection Account the aggregate
Advances on the Receivables pursuant to Section 4.4(a). To the extent that the
Servicer fails to make an Advance pursuant to Section 4.4(a) on the date
required, the Servicer shall so notify the Issuer and the Indenture Trustee in
writing specifying the amount of the Advance and the Receivable to which such
Advance related, and the Indenture Trustee shall withdraw such amount (or, if
determinable by the Servicer, 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.

     SECTION 4.5 Additional Deposits. (a) The Depositor and the Servicer shall
deposit in the Collection Account the aggregate Purchase Amounts with respect
to Purchased Receivables pursuant to Sections 2.3 and 3.7, respectively, and

made, in immediately available funds, on the Business Day preceding the
Payment Date related to such Collection Period.

     (b) The Indenture Trustee, in accordance with the written instructions of
the Servicer, shall, on each Payment Date make a withdrawal from the Reserve
Account (i) first, in an amount equal to the Reserve Account Excess Amount for
such Payment Date and (ii) second, in an amount equal to the amount (if
positive) calculated by the Servicer pursuant to the second sentence of
Section 4.6(b).

     (c) The Indenture Trustee, in accordance with the written instructions of
the Servicer, shall, on each Payment Date make a withdrawal from the Yield

Amount. In addition, the Servicer shall calculate on or before each
Determination Date the difference, if any, between the Total Required Payment
and the Available Funds and, pursuant to Section 4.5(b), the Indenture Trustee
shall withdraw funds from the Reserve Account in an amount equal to the lesser
of such difference (if positive) or the balance of such Reserve Account.

     (c) On each Payment Date, the Servicer shall instruct the Indenture
Trustee (based on the information contained in the Servicer's Certificate
delivered on or before the related Determination Date pursuant to Section
3.9), to make the following withdrawals from the Collection Account and make
deposits, distributions and payments, to the extent of Available Funds for
such Payment Date (plus funds, if any, deposited in the Collection Account

     the Class A Notes on a pro rata basis;

          (iii) third, to the Noteholders, the Priority Note Principal
     Payment, if any, for such Payment Date to be distributed in the same

     (iii) above) for such Payment Date;

          (vi) sixth, if such Payment Date is a Final Scheduled Payment Date
     for any Class, to the Principal Distribution Account, the amount
     necessary to reduce the remaining principal amount of such Class to zero
     after giving effect to the amount, if any, to be applied on such Payment
     Date to such Class from funds deposited pursuant to clauses (iii) and (v)
     above;

Account in the name "JPMorgan Chase Bank, National Association, as Indenture
Trustee, as secured party from USAA Auto Owner Trust 2005-4", initially at the
corporate trust department of the Indenture Trustee, which shall be designated
as the "Reserve Account" (the Reserve Account, together with the Collection
Account (including the Principal Distribution Account) and the Yield
Supplement Account, the "Trust Accounts"). The Reserve Account shall be under
the sole dominion and control of the Indenture Trustee; provided, that the
Servicer may make deposits to the Reserve Account in accordance with the Basic
Documents. The Reserve Account will be established and maintained pursuant to
an account agreement which specifies New York law as the governing law. In
addition, the Reserve Account shall be established and maintained at an
institution which agrees in writing that for so long as the Notes are
Outstanding it will comply with entitlement orders (as defined in Article 8 of
the UCC) originated by the Indenture Trustee without further consent of the
Issuer. On the Closing Date, the Depositor shall deposit the Reserve Initial
Deposit into the Reserve Account. The Reserve Account and all amounts,
securities, investments, financial assets and other property deposited in or
credited to the Reserve Account (such amounts, the "Reserve Account Property")
shall be held by the Indenture Trustee as secured party for the benefit of the
Noteholders and, after payment in full of the Notes, as agent of the Owner
Trustee and as part of the Trust Property, and all deposits to and withdrawals
from there from shall be made only upon the terms and conditions of the Basic
Documents.

     The Reserve Account Property shall, to the extent permitted by applicable
law, rules and regulations, be invested, as directed in writing by the
Depositor, by the bank or trust company then maintaining the Reserve Account
in Permitted Investments that mature not later than the next Payment Date or
such later date that satisfies the Rating Agency Condition, and such Permitted
Investments shall be held to maturity. If JPMorgan Chase Bank, National
Association is the Indenture Trustee, in the absence of written direction, all
funds shall be retained uninvested. All interest and other income (net of
losses and investment expenses) on funds on deposit in the Reserve Account
shall be deposited therein. The Indenture Trustee shall not be


                                      20
<PAGE>


liable for investment losses in Permitted Investments made in accordance with
directions from the Depositor. In the event the Reserve Account is no longer
to be maintained at the corporate trust department of the Indenture Trustee,
the Servicer shall, with the Indenture Trustee's or Owner Trustee's assistance
as necessary, cause an Eligible Deposit Account to be established as the
Reserve Account within ten (10) Business Days (or such longer period not to
exceed thirty (30) calendar days as to which each Rating Agency may consent)
and give written notice of the location and account number of such account to
the Indenture Trustee.

          (ii) With respect to Reserve Account Property:

               (A) 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
          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; and

               (B) 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.

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

     (b) If the Servicer pursuant to Section 4.4 determines on or before any
Determination Date that it is required to make an Advance and does not do so
from its own funds, the Servicer shall promptly instruct the Indenture Trustee
in writing to draw funds, in an amount specified by the Servicer, from the
Reserve Account and deposit them in the Collection Account to cover any
shortfall. Such payment shall be deemed to have been made by the Servicer
pursuant to Section 4.4 for purposes of making distributions pursuant to this
Agreement, but shall not otherwise satisfy the Servicer's obligation to
deliver the amount of the Advances to the Indenture Trustee, and the Servicer
shall within two (2) Business Days replace any funds in the Reserve Account so
used.

     (c) Following the payment in full of the aggregate principal amount of
the Notes and the Certificate Balance and of all other amounts owing or to be
distributed hereunder or under the Indenture or the Trust Agreement to
Noteholders and Certificateholders, the Indenture Trustee and the Owner
Trustee and the termination of the Trust, any remaining Reserve Account
Property shall be distributed to the Depositor.

     (d) The Depositor shall be permitted to sell, transfer, convey or assign
in any manner its rights in the Reserve Account under Section 4.7(c), together
with its rights to receive amounts under Sections 4.6(c) and 4.6(d) of this
Agreement and Sections 5.4(b)(v), 8.2(c) and 8.2(d) of


                                      21
<PAGE>


the Indenture in accordance with the priority of payments, provided that each
of the following conditions shall be satisfied:

          (i) the Rating Agency Condition is satisfied with respect to such
     action;

          (ii) such action shall not, as evidenced by an Opinion of Counsel,
     cause the Issuer to be characterized as an association (or a publicly
     traded partnership) taxable as a corporation for federal income tax
     purposes; and

          (iii) the transferee or assignee agrees in writing to take positions
     for federal income tax purposes consistent with the federal income tax
     positions taken previously by the Depositor.

     SECTION 4.8 Yield Supplement Account. (a) (i) The Servicer shall, prior
to the Closing Date, cause to be established and maintained an Eligible
Deposit Account in the name "JPMorgan Chase Bank, National Association, as
Indenture Trustee, as secured party from USAA Auto Owner Trust 2005-4",
initially at the corporate trust department of the Indenture Trustee, which
shall be designated as the "Yield Supplement Account." The Yield Supplement
Account shall be under the sole dominion and control of the Indenture Trustee.
The Yield Supplement Account will be established and maintained pursuant to an
account agreement which specifies New York law as the governing law. In
addition, the Yield Supplement Account shall be established and maintained at
an institution which agrees in writing that for so long as the Notes are
Outstanding it will comply with entitlement orders (as defined in Article 8 of
the UCC) originated by the Indenture Trustee without further consent of the
Issuer. On the Closing Date, the Depositor shall deposit the Yield Supplement
Account Initial Deposit into the Yield Supplement Account. No additional
deposits to the Yield Supplement Account shall be made. The Yield Supplement
Account and all amounts, securities, investments, financial assets and other
property deposited in or credited to the Yield Supplement Account (such
amounts, the "Yield Supplement Account Property") shall be held by the
Indenture Trustee as secured party for the benefit of the Noteholders and,
after payment in full of the Notes, as agent of the Owner Trustee and as part
of the Trust Property, and all withdrawals from there from shall be made only
upon the terms and conditions of the Basic Documents.

     The Yield Supplement Account Property shall, to the extent permitted by
applicable law, rules and regulations, be invested, as directed in writing by
the Depositor, by the bank or trust company then maintaining the Yield
Supplement Account in Permitted Investments that mature not later than the
next Payment Date or such later date that satisfies the Rating Agency
Condition, and such Permitted Investments shall be held to maturity. If
JPMorgan Chase Bank, National Association is the Indenture Trustee, in the
absence of written direction, all funds shall be retained uninvested. All
interest and other income (net of losses and investment expenses) on funds on
deposit in the Yield Supplement Account shall be deposited therein. The
Indenture Trustee shall not be liable for investment losses in Permitted
Investments made in accordance with directions from the Depositor. In the
event the Yield Supplement Account is no longer to be maintained at the
corporate trust department of the Indenture Trustee, the Servicer shall, with
the Indenture Trustee's or Owner Trustee's assistance as necessary, cause an
Eligible Deposit Account to be established as the Yield Supplement Account
within ten (10) Business Days (or


                                      22
<PAGE>


such longer period not to exceed thirty (30) calendar days as to which each
Rating Agency may consent) and give written notice of the location and account
number of such account to the Indenture Trustee.

          (ii) With respect to Yield Supplement Account Property:

          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 institution maintaining the Yield Supplement Account in

     SECTION 7.1 Events of Servicing Termination. (a) If any one of the
following events ("Events of Servicing Termination") shall occur and be
continuing:

          (i) Any failure by the Servicer (or, so long as the Seller is the
     Servicer, the Seller) to deliver to the Owner Trustee or the Indenture
     Trustee any proceeds or payment required to be so delivered under the
     terms of the Notes and the Certificates and this Agreement that shall
     continue unremedied for a period of five (5) Business Days after written
     notice of such failure is received by the Servicer or the Seller, as the
     case may be, from the Owner Trustee or the Indenture Trustee or after
     discovery of such failure by an officer of the Servicer or the Seller, as
     the case may be; or

          (ii) Failure on the part of the Servicer (or, so long as the Seller
     is the Servicer, the Seller) duly to observe or to perform in any
     material respect any other covenants or agreements, as the case may be,
     set forth in the Notes, the Certificates or in this Agreement, which
     failure shall (A) materially and adversely affect the rights of
     Noteholders or Certificateholders and (B) continue unremedied for a
     period of ninety (90) days after the date on which written notice of such
     failure, requiring the same to be remedied, shall have been given (1) to
     the Servicer or the Seller, as the case may be, by the Owner Trustee or
     the Indenture Trustee, or (2) to the Owner Trustee, the Indenture
     Trustee, the Seller and the Servicer by the Noteholders of Notes
     evidencing not less than 25% of the principal amount of the Notes or, if
     no Notes are outstanding, by Certificateholders of Certificates
     evidencing not less than 25% of the Certificate Balance; or

          (iii) So long as the Bank or another depository institution is not
     the Servicer, the entry of a decree or order by a court or agency or
     supervisory authority having jurisdiction in the premises for the
     appointment of a conservator, receiver, or liquidator for the Servicer in
     any insolvency, readjustment of debt, marshalling of assets and
     liabilities, or similar proceedings, or for the winding up or liquidation
     of its respective


                                      32
<PAGE>


     affairs, and the continuance of any such decree or order unstayed and in
     effect for a period of sixty (60) consecutive days; or

          (iv) So long as the Bank or another depository institution is not
     the Servicer, the consent by the Servicer to the appointment of a
     conservator or receiver or liquidator in any insolvency, readjustment of
     debt, marshalling of assets and liabilities, or similar proceedings of or
     relating to the Servicer of or relating to substantially all of its
     property; or the Servicer shall admit in writing its inability to pay its
     debts generally as they become due, file a petition to take advantage of
     any applicable insolvency or reorganization statute, make an assignment
     for the benefit of its creditors, or voluntary suspend payment of its
     obligations or become insolvent;

then the Indenture Trustee shall promptly notify each Rating Agency, and in
each and every case, so long as an Event of Servicing Termination shall not
have been remedied, either the Indenture Trustee or the holders of Notes
evidencing not less than a majority of the principal amount of the Notes
Outstanding (or, if no Notes are Outstanding, Certificates evidencing not less
than a majority of the Certificate Balance), by notice then given in writing
to the Servicer (and to the Indenture Trustee and the Owner Trustee if given
by the Noteholders and to the Owner Trustee if given by the
Certificateholders) (with a copy to the Rating Agencies) 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 Notes, the
Certificates or the Trust Property or otherwise, shall pass to and be vested
in the Indenture Trustee or such Successor Servicer as may be appointed under
Section 7.2; and, without limitation, the Indenture Trustee and the Owner
Trustee are hereby authorized and empowered to execute and deliver, on behalf
of the predecessor Servicer, as attorney-in-fact or otherwise, any and all
documents and other instruments, and to do or accomplish all other acts or
things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement of the
Receivables and related documents, or otherwise.

     (b) Upon termination of the Servicer under Section 7.1(a), the
predecessor Servicer shall cooperate with the Indenture Trustee, the Owner
Trustee and such Successor Servicer in effecting the termination of the
responsibilities and rights of the predecessor Servicer under this Agreement,
including the transfer to the Indenture Trustee or such Successor Servicer for
administration of all cash amounts that shall at the time be held by the
predecessor Servicer for deposit, or shall thereafter be received with respect
to a Receivable and the delivery of the Receivable Files and the related
accounts and records maintained by the Servicer. All reasonable costs and
expenses (including attorneys' fees) incurred in connection with transferring
the Receivable Files to the Successor Servicer and amending this Agreement to
reflect such succession as Servicer pursuant to this Section 7.1 shall be paid
by the predecessor Servicer upon presentation of reasonable documentation of
such costs and expenses.

     SECTION 7.2 Appointment of Successor Servicer. (a) Upon the Servicer's
receipt of notice of termination pursuant to Section 7.1 or the Servicer's
resignation in accordance with the terms of this Agreement, the predecessor
Servicer shall continue to perform its functions as Servicer under this
Agreement, in the case of termination, only until the date specified in such


                                      33
<PAGE>


termination notice or, if no such date is specified in a notice of
termination, until receipt of such notice and, in the case of resignation,
until the later of (x) the date 90 days from the delivery to the Indenture
Trustee and the Owner Trustee of written notice of such resignation (or
written confirmation of such notice) in accordance with the terms of this
Agreement and (y) the date upon which the predecessor Servicer shall become
unable to act as Servicer, as specified in the notice of resignation and
accompanying Opinion of Counsel. In the event of the Servicer's resignation or
termination hereunder, the Issuer shall appoint a Successor Servicer, and the
Successor Servicer shall accept its appointment by a written assumption in
form acceptable to the Owner Trustee and the Indenture Trustee (with a copy to
each Rating Agency). In the event that a Successor Servicer has not been
appointed at the time when the predecessor Servicer has ceased to act as
Servicer in accordance with this Section 7.2, the Indenture Trustee without
further action shall automatically be appointed the Successor Servicer and the
Indenture Trustee shall be entitled to the Servicing Fee. The Indenture
Trustee may resign as the Servicer by giving written notice of such
resignation to the Issuer and in such event shall be released from such duties
and obligations, such release not to be effective until the date a Successor
Servicer enters into a written assumption as provided in this Section. Upon
delivery of any such notice to the Issuer, the Issuer shall obtain a new
servicer as the Successor Servicer in accordance with this Section.
Notwithstanding the above, if the Indenture Trustee shall be legally unable so
to act or if, within 30 days after the delivery of its notice of resignation,
the Issuer shall not have obtained a Successor Servicer, the Indenture Trustee
shall appoint, or petition a court of competent jurisdiction to appoint, any
established institution, having a net worth of not less than $100,000,000 and
whose regular business shall include the servicing of automotive receivables,
as the successor to the Servicer under this Agreement; provided that the
Rating Agency Condition shall be satisfied in connection with such
appointment.

     (b) Upon appointment, the Successor Servicer shall be the successor in
all respects to the predecessor Servicer and shall be subject to all the
responsibilities, duties, and liabilities arising thereafter relating thereto
placed on the predecessor Servicer, by the terms and provisions of this
Agreement.

     (c) In connection with such appointment, subject to Section 3.7(e) of the
Indenture, the Indenture Trustee may make such arrangements for the
compensation of such Successor Servicer out of payments on Receivables as it
and such Successor Servicer shall agree; provided, however, that no such
compensation shall be in excess of that permitted the predecessor Servicer
under this Agreement. The Indenture Trustee and such Successor Servicer shall
take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession.

     SECTION 7.3 Repayment of Advances. If the identity of the Servicer shall
change, the predecessor Servicer shall be entitled to receive to the extent of
available funds reimbursement for Outstanding Advances pursuant to Section 4.3
and 4.4, in the manner specified in Section 4.6, with respect to all Advances
made by the predecessor Servicer.

     SECTION 7.4 Notification to Noteholders and Certificateholders. Upon any
termination of, or appointment of a successor to, the Servicer pursuant to
this Article VII, the Indenture Trustee shall give prompt written notice
thereof to Noteholders, and the Owner Trustee shall


                                      34
<PAGE>


give prompt written notice thereof to Certificateholders at their respective
addresses of record and to each Rating Agency.

     SECTION 7.5 Waiver of Past Events of Servicing Termination. The holders
of Notes evidencing not less than a majority of the principal amount of the
Notes (or, if no Notes are Outstanding, holders of Certificates evidencing not
less than a majority of the Certificate Balance) may, on behalf of all
Noteholders and Certificateholders, waive any Event of Servicing Termination
hereunder and its consequences, except an event resulting from the failure to
make any required deposits to or payments from any of the Trust Accounts or
the Certificate Distribution Account in accordance with this Agreement, which
shall require the unanimous vote of all Holders of Outstanding Securities.
Upon any such waiver of a past Event of Servicing Termination, such Event of
Servicing Termination shall cease to exist, and shall be deemed to have been
remedied for every purpose of this Agreement. No such waiver shall extend to
any subsequent or other event or impair any right consequent thereon. The
Issuer shall provide written notice of any such waiver to the Rating Agencies.

                                 ARTICLE VIII

                                  TERMINATION

     SECTION 8.1 Optional Purchase of All Receivables. As of the last day of
any Collection Period as of which the Pool Factor shall be equal to or less
than the Optional Purchase Percentage, the Servicer shall have the option to
purchase the Trust Property from the Trust. To exercise such option, the
Servicer shall deposit pursuant to Section 4.5 in the Collection Account an
amount equal to the lesser of (i) the aggregate Purchase Amount for the
Receivables and (ii) the fair market value of the Receivables, and shall
succeed to all interests in and to the Trust. Notwithstanding the foregoing,
the Servicer shall not be permitted to exercise such option unless the amount
to be deposited in the Collection Account pursuant to the preceding sentence
is greater than or equal to the sum of the outstanding principal amount of the
Notes and the Certificate Balance and all accrued but unpaid interest
(including any over due interest) thereon. The amount deposited in the
Collection Account pursuant to this Section 8.1 shall be used on the next
Payment Date to make payments in full to Noteholders and Certificateholders in
the manner set forth in Article IV. The purchase of the Trust Property
pursuant to this Section shall not be permitted unless either (i) the
Servicer's long-term unsecured debt is rated at the time of such purchase at
least Baa3 by Moody's or (ii) the Servicer provides to the Indenture Trustee
and the Owner Trustee an Opinion of Counsel in form reasonably satisfactory to
the Indenture Trustee and the Owner Trustee and in form and substance
satisfactory to Moody's to the effect that such purchase will not constitute a
fraudulent transfer of assets of the Servicer under applicable state and
federal law; provided that this sentence may be deleted or modified with the
consent of Moody's and without the consent of any Securityholder, the
Indenture Trustee or the Owner Trustee.

     SECTION 8.2 Succession Upon Satisfaction and Discharge of Indenture.
Following the satisfaction and discharge of the Indenture and the payment in
full of the principal of and interest on the Notes, to the extent permitted by
applicable law and until the payment of all amounts owing or to be distributed
hereunder to the Certificateholders or the Depositor, the Indenture


                                      35
<PAGE>


Trustee will continue to carry out its obligations hereunder as agent for the
Owner Trustee, including without limitation making distributions from the
Collection Account in accordance with Section 4.6, making withdrawals from the
Reserve Account in accordance with Section 4.5(b) and Section 4.7 and making
withdrawals from the Yield Supplement Account in accordance with Section
4.5(c) and Section 4.8.

     SECTION 9.1 Amendment. (a) This Agreement may be amended by the
Depositor, the Servicer and the Issuer, with the consent of the Indenture
Trustee and the Owner Trustee to the extent that their respective rights or
obligations may be affected thereby (which consent may not be unreasonably
withheld), but without the consent of any of the Noteholders or the
Certificateholders, to cure any ambiguity, to correct or supplement any
provisions in this Agreement, or to add any provisions to or change or
eliminate any provisions or to modify the rights of the Noteholders or
Certificateholders; provided, however, that (i) such action shall not, as
evidenced by either an Opinion of Counsel or an Officer's Certificate
delivered to the Owner Trustee and the Indenture Trustee, materially and
adversely affect the interests of any Noteholder or Certificateholder and (ii)
the Rating Agency Condition shall be satisfied.

     (b) This Agreement may also be amended from time to time by the
Depositor, the Servicer and the Issuer, with the consent of the Indenture
Trustee and the Owner Trustee to the extent that their respective rights or
obligations may be affected thereby (which consent may not be unreasonably
withheld) and with the consent of (i) the Noteholders of Notes evidencing not
less than a majority of the principal amount of each Class of Notes and (ii)
the Certificateholders of Certificates evidencing not less than a majority of
the Certificate Balance (which consent of any holder of a Note or holder of a
Certificate given pursuant to this Section 9.1 or pursuant to any other
provision of this Agreement shall be conclusive and binding on such Note or
Certificate, as the case may be, and on all future holders of such Note or
holders of such Certificate, as the case may be, and of any Note or
Certificate, as applicable, issued upon the transfer thereof or in exchange
thereof or in lieu thereof whether or not notation of such consent is made
upon such Note or the Certificate), for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this
Agreement, or of modifying in any manner the rights of the Noteholders or the
Certificateholders; provided, however, that no such amendment shall (A)
increase or reduce in any manner the amount of, or accelerate or delay the
timing of, or change the allocation or priority of, collections of payments on
Receivables or distributions that shall be required to be made on any Note or
Certificate or change any Note Interest Rate or any Certificate Rate or the
amount required to be on deposit in the Reserve Account, without the consent
of all Noteholders or Certificateholders or (B) reduce the aforesaid
percentage required to consent to any such amendment, without the consent of
the holders of all Notes and holders of all Certificates. Notwithstanding the
foregoing, the Depositor may decrease the Specified Reserve Balance upon
satisfaction of the Rating Agency Condition without the consent of any other
party hereto or any Noteholder or Certificateholder.

shall furnish written notification of the substance of such amendment to each
Certificateholder, the Indenture Trustee and each Rating Agency and the
Indenture Trustee will provide notification of the substance of such amendment
to each Noteholder. It shall not be necessary for the consent of Noteholders
or the Certificateholders pursuant to this Section 9.1 to approve the
particular form of any proposed amendment or consent, but it shall be
sufficient if such consent shall approve the substance thereof. The manner of
obtaining such consents (and any other consents of Noteholders and
Certificateholders provided for in this Agreement) and of evidencing the
authorization of the execution thereof by Noteholders and Certificateholders
shall be subject to such reasonable requirements as the Owner Trustee and the
Indenture Trustee may prescribe, including the establishment of record dates
pursuant to the Note Depository Agreement.

     (e) Prior to the execution of any amendment to this Agreement, the Owner
Trustee and the Indenture Trustee shall be entitled to receive and rely upon
an Opinion of Counsel stating that the execution of such amendment is
authorized or permitted by this Agreement and the Opinion of Counsel referred
to in Section 9.2(i)(1). The Owner Trustee or the Indenture Trustee may, but
shall not be obligated to, enter into any such amendment which affects such
Owner Trustee's or Indenture Trustee's own rights, duties or immunities under
this Agreement or otherwise.

     SECTION 9.2 Protection of Title to Trust Property. (a) The Depositor and

continuation statements, all in such manner and in such places as may be
required by law fully to preserve, maintain, and protect the interest of the
Issuer and the Indenture Trustee for the benefit of the Noteholders in the
Receivables and in the proceeds thereof. The Depositor or the Seller, as
applicable, shall deliver (or cause to be delivered) to the Owner Trustee and
the Indenture Trustee file-stamped copies of, or filing receipts for, any
document filed as provided above, as soon as available following such filing.

     (b) None of the Depositor, the Seller or the Servicer shall change its
name, identity, or corporate structure in any manner that would, could, or
might make any financing statement or continuation statement filed by the
Seller or the Depositor in accordance with paragraph (a) above seriously
misleading within the meaning of ss. 9-506 of the UCC, unless it shall have
given the Owner Trustee and the Indenture Trustee at least 10 days' prior
written notice thereof, with a copy to the Rating Agencies, and shall have
promptly filed appropriate amendments to all previously filed financing
statements or continuation statements.

     (c) The Depositor, the Seller and the Servicer shall give the Owner
Trustee and the Indenture Trustee at least ten (10) days' prior written notice
of any relocation of its principal executive office or change in the

any amendment of any previously filed financing or continuation statement or
of any new financing statement and shall promptly file any such amendment or
new financing statement. The Servicer


                                      37

Receivable and the amounts from time to time deposited in the Collection
Account and the Reserve Account in respect of such Receivable.

     (e) The Servicer shall maintain its computer systems so that, from and
after the time of conveyance under this Agreement of the Receivables to the
Issuer, the Servicer's master computer records (including any back-up
archives) that refer to a Receivable shall indicate clearly, by numerical code
or otherwise, that such Receivable is owned by the Issuer and has been pledged
to the Indenture Trustee pursuant to the Indenture. Indication of the Issuer's
and the Indenture Trustee's interest in a Receivable shall not be deleted from
or modified on the Servicer's computer systems until, and only until, the
Receivable shall have been paid in full or repurchased.

     (f) If at any time the Seller or the Servicer shall propose to sell,
grant a security interest in, or otherwise transfer any interest in automotive
receivables to any prospective purchaser, lender, or other transferee, the
Servicer shall give to such prospective purchaser, lender, or other transferee
computer tapes, records, or print-outs (including any restored from back-up
archives) that, if they shall refer in any manner whatsoever to any
Receivable, shall indicate clearly that such Receivable has been conveyed to
and is owned by the Issuer and has been pledged to the Indenture Trustee.

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

Trustee:

          (1) promptly after the execution and delivery of this Agreement and
     of each amendment thereto, an Opinion of Counsel either (A) stating that,

     interest of the Issuer and the Indenture Trustee in the Receivables, and
     reciting the details of such filings or referring to prior Opinions of

     opinion of such Counsel, no such action shall be necessary to preserve
     and protect such interest; and

taken in the following year to preserve and protect such interest.

     (j) For the purpose of facilitating the execution of this Agreement and

     The following rules of construction and usage shall be applicable to any

followed by "without limitation."

     The definitions contained in this Appendix are equally applicable to both
the singular and plural forms of such terms and to the masculine as well as to

     Any agreement, instrument or statute defined or referred to below or in
any agreement or instrument that is governed by this Appendix means such

supplemented, including (in the case of agreements or instruments) by waiver
or consent and (in the case of statutes) by succession of comparable successor
statutes and includes (in the case of agreements or instruments) references to
