               (ii)  the Depositor is duly qualified to do business as a foreign
     limited liability company in good standing and has obtained all necessary
     licenses and approvals in each jurisdiction in which the failure to so
     qualify or to obtain such licenses and approvals would materially and
     adversely affect the performance by the Depositor of its obligations under,
     or the validity or enforceability of, this Agreement, any of the other
     Transaction Documents to which the Depositor is a party, the Receivables,
     the Notes or the Certificates;

               (iii) the Depositor has the power and authority to execute,
     deliver and perform its obligations under this Agreement and the other
     Transaction Documents to which it is a party, and the Depositor has the
     power and authority to sell, assign, transfer and convey the property to be
     sold and transferred to and deposited with the Trust and has duly
     authorized such transfer and deposit by all necessary limited liability

     Agreement and the other Transaction Documents to which the Depositor is a
     party have been duly authorized by the Depositor by all necessary limited
     liability company action;

               (iv)  the execution, delivery and performance by the Depositor of
     this Agreement and the other Transaction Documents to which the Depositor
     is a party, the consummation of the transactions contemplated hereby and
     thereby and the fulfillment of the terms hereof and thereof will not
     conflict with, result in a breach of any of the terms and provisions of or
     constitute (with or without notice or lapse of time or both) a default
     under the articles of formation or limited liability company agreement of
     the Depositor or any material indenture, agreement, mortgage, deed of trust
     or other instrument to which the Depositor is a party or by which the
     Depositor is bound or to which any of its properties are subject, or result
     in the creation or imposition of any lien upon any of its properties
     pursuant to the terms of any such indenture, agreement, mortgage, deed of
     trust or other instrument (other than pursuant to this Agreement), or
     violate any law, order, rule or regulation applicable to the Depositor or

<PAGE>

               (v)   there are no proceedings or investigations pending or, to
     the knowledge of the Depositor, threatened against the Depositor before any
     court, regulatory body, administrative agency or other governmental
     instrumentality having jurisdiction over the Depositor or its properties

               (vi)  the representations and warranties of the Depositor in
     Section 3.01 of the Receivables Purchase Agreement are true and correct.

          SECTION 2.11  Federal Income Tax Matters. The Certificateholders
acknowledge that it is their intent and that they understand it is the intent of
the Depositor and the Servicer that, for purposes of federal income, state and
local income and franchise tax and any other income taxes, the Trust will be
treated either as a disregarded entity under Treasury Regulation Section
301.7701-3 or as a partnership, and that the Certificateholders will be treated
as partners in that partnership. The Certificateholders by acceptance of a
Certificate agree to such treatment and agree to take no action inconsistent
with such treatment. For each calendar quarter, other than periods in which
there is only one Certificateholder:

               (i)   net income of the Trust for any calendar quarter as
     determined for federal income tax purposes (and each item of income, gain,
     credit, loss or deduction entering into the computation thereof) shall be
     allocated among the Certificateholders as of the first day following the
     end of such quarter in proportion to their Certificate Percentage Interest
     on such date; and

               (ii)  net losses of the Trust, if any, for any calendar quarter
     as determined for federal income tax purposes (and each item of income,
     gain, credit, loss or deduction entering into the computation thereof)
     shall be allocated among the Certificateholders as of the first day
     following the end of such quarter in proportion to their Certificate
     Percentage Interest on such date.

          The Certificateholders are authorized to modify the allocations in
this Section 2.11 if necessary or appropriate, in their sole discretion, for the
allocations to reflect fairly the economic income, gain, credit, loss or
deduction to the Certificateholders or as otherwise required by the Code.

                                   ARTICLE III
                     CERTIFICATES AND TRANSFER OF INTERESTS

          SECTION 3.1   Initial Ownership. Upon the formation of the Trust by
the contribution by the Depositor pursuant to Section 2.5 and until the issuance
of the Certificates, the Depositor shall be the sole beneficiary of the Trust.

          SECTION 3.2   The Certificates. The Certificates shall be issued in
one or more registered, definitive, physical certificates, in the form set forth
in Exhibit A. The Certificates may be in printed or typewritten form and shall
be executed on behalf of the Trust by manual or facsimile signature of an
authorized officer of the Owner Trustee. Certificates bearing the manual or
facsimile signatures of individuals who were, at the time when such signatures
shall have been affixed, authorized to sign on behalf of the Trust, shall be
validly issued and entitled to the benefits of this Agreement, notwithstanding
that such individuals or any of them shall have ceased to be so authorized prior
to the authentication and delivery of such Certificates or did not hold such
offices at the date of authentication and delivery of such Certificates.

          If Transfer of the Certificates is permitted pursuant to this Section
3.2 and Section 3.4, a transferee of a Certificate shall become a
Certificateholder, and shall be entitled to the rights and subject to the
obligations of a Certificateholder hereunder upon such transferee's acceptance
of a Certificate duly registered in such transferee's name pursuant to Section
3.4.

          SECTION 3.3   Authentication of Certificates. Concurrently with the
initial sale of the Receivables to the Trust pursuant to the Sale and Servicing
Agreement, the Owner Trustee shall cause the Certificates to be executed on
behalf of the Trust, authenticated and delivered to or upon the written order of
the Depositor, signed by its president, any vice president, any assistant vice
president, its treasurer, any assistant treasurer, its secretary or any
assistant secretary, without further limited liability company action by the
Depositor. No Certificate shall entitle its Holder to any benefit under this
Agreement, or shall be valid for any purpose, unless there shall appear on such
Certificate a certificate of authentication substantially in the form set forth
in Exhibit A executed by the Owner Trustee by manual signature, which
authentication shall constitute conclusive evidence that such Certificate shall
have been duly authenticated and delivered hereunder. All Certificates shall be
dated the date of their authentication. Upon issuance, authentication and
delivery pursuant to the terms hereof, the Certificates will be entitled to the
benefits of this Agreement.

          SECTION 3.4   Registration of Certificates; Transfer and Exchange of
Certificates.

          (a)  The Owner Trustee initially shall be the registrar (the
"Certificate Registrar") for the purpose of registering Certificates and
Transfers of Certificates as herein provided. The Certificate Registrar shall
cause to be kept, at the office or agency maintained pursuant to Section 3.8, a
register (the "Certificate Register") in which, subject to such reasonable
regulations as it may prescribe, the Certificate Registrar shall provide for the
registration of Certificates and the registration of Transfers of Certificates.
Upon any resignation of any Certificate Registrar, the Owner Trustee shall, upon
receipt of written instructions from the Depositor, promptly appoint a
successor.

                                       9

<PAGE>

          (b)  The Certificates may not be acquired by or for the account of (i)
an employee benefit plan (as defined in Section 3(3) of ERISA) that is subject
to the provisions of Title 1 of ERISA, (ii) a plan described in Section
4975(e)(1) of the Code or (iii) any entity whose underlying assets include plan
assets by reason of a plan's investment in the entity (each, a "Plan"). Each
Certificateholder, by its acceptance of a Certificate, shall be deemed to have
represented and warranted that such Certificateholder (A) is not a Plan and is
not a Person acting on behalf of a Plan or a Person using the assets of a Plan
to effect the transfer of such Certificate, and (B) is not an insurance company
purchasing a Certificate with funds contained in an "insurance company general
account" (as defined in Section V(e) of Prohibited Transaction Class Exemption
95-60 ("PTCE 95-60")) that includes the assets of a Plan for purposes of the
Plan Asset Regulation.

          Any person who is not an affiliate of the Seller and acquires more
than 49.9% of the Certificates will be deemed to represent that it is not a
party in interest (within the meaning of ERISA) or a disqualified person (within
the meaning of Section 4975(e)(2) of the Code) with respect to any Plan, other
than a Plan that it sponsors for the benefit of its employees, and that no Plan
with respect to which it is a party in interest has or will acquire any interest
in the Notes.

          To the extent permitted under applicable law (including, but not
limited to, ERISA), neither the Owner Trustee nor the Certificate Registrar
shall be under any liability to any Person for any registration of transfer of
any Certificate that is in fact not permitted or for taking any other action
with respect to such Certificate under the provisions of this Agreement so long
as such transfer was registered by the Owner Trustee or the Certificate
Registrar in accordance with this Agreement.

          (c)  Upon surrender for registration of Transfer of any Certificate at
the office or agency of the Certificate Registrar to be maintained as provided
in Section 3.8, and upon compliance with any provisions of this Agreement
relating to such Transfer, the Owner Trustee shall execute on behalf of the
Trust and the Owner Trustee shall authenticate and deliver to the
Certificateholder making such surrender, in the name of the designated
transferee or transferees, one or more new Certificates in any authorized
denomination evidencing the same aggregate interest in the Trust. Each
Certificate presented or surrendered for registration of Transfer or exchange
shall be accompanied by a written instrument of transfer and accompanied by IRS
Form W-8 BEN, W-8 ECI or W-9, as applicable, in form satisfactory to the Owner
Trustee and the Certificate Registrar, duly executed by the Certificateholder or
his attorney duly authorized in writing. Each Certificate presented or
surrendered for registration of Transfer or exchange shall be canceled and
subsequently disposed of by the Certificate Registrar in accordance with its
customary practice. No service charge shall be made for any registration of
Transfer or exchange of Certificates, but the Owner Trustee or the Certificate
Registrar may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any Transfer or
exchange of Certificates.

          SECTION 3.5   Mutilated, Destroyed, Lost or Stolen Certificates.

          (a)  If (i) any mutilated Certificate is surrendered to the
Certificate  Registrar,  or the Certificate  Registrar  receives evidence to its
satisfaction  of the  destruction,  loss or theft of any  Certificate,  and (ii)
there is delivered to the Certificate Registrar and the Owner Trustee such

                                       10

<PAGE>

security or indemnity as may be required by them to hold each of the Trust, the
Certificate Registrar and the Owner Trustee harmless, then, in the absence of
notice to the Trust, the Certificate Registrar or the Owner Trustee that such
Certificate has been acquired by a "protected purchaser" (as defined in the
Relevant UCC), the Owner Trustee shall execute on behalf of the Trust and the
Owner Trustee shall authenticate and deliver, in exchange for, or in lieu of,
any such mutilated, destroyed, lost or stolen Certificate, as the case may be, a
replacement Certificate, as the case may be, of like tenor and Certificate
Percentage Interest. If, after the delivery of such replacement Certificate or
payment of a destroyed, lost or stolen Certificate pursuant to the proviso to
the preceding sentence, a "protected purchaser" (as defined in the Relevant UCC)
of the original Certificate in lieu of which such replacement Certificate was
issued presents for payment such original Certificate, the Trust and the Owner
Trustee shall be entitled to recover such replacement Certificate (or such
payment) from the Person to whom such replacement Certificate was delivered or
any Person taking such replacement Certificate from such Person to whom such
replacement Certificate was delivered or any assignee of such Person, except a
"protected purchaser" (as defined in the Relevant UCC), and shall be entitled to
recover upon the security or indemnity provided therefor to the extent of any
loss, damage, cost or expense incurred by the Trust or the Owner Trustee in
connection therewith.

          (b)  Upon the issuance of any replacement Certificate under this
Section 3.5, the Trust may require the payment by the Holder of such Certificate
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with such issuance and any other reasonable expenses
(including the fees and expenses of the Owner Trustee) related thereto.

          (c)  Every replacement Certificate issued pursuant to this Section 3.5
in replacement of any mutilated, destroyed, lost or stolen Certificate shall
constitute an original additional contractual obligation of the Trust, whether
or not the mutilated, destroyed, lost or stolen Certificate shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Agreement equally and proportionately with any and all other Certificates duly
issued hereunder.

          (d)  The provisions of this Section 3.5 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Certificates.

          SECTION 3.6   Persons Deemed Owners. Prior to due presentation of a
Certificate for registration of transfer, the Owner Trustee, the Certificate
Registrar and any Paying Agent may treat the Person in whose name such
Certificate is registered in the Certificate Register (as of the day of
determination) as the owner of such Certificate for the purpose of receiving
distributions pursuant to Section 5.2 and for all other purposes whatsoever, and
none of the Owner Trustee, the Certificate Registrar or any Paying Agent shall
be bound by any notice to the contrary.

          SECTION 3.7   Access to List of Certificateholders' Names and
Addresses. The Certificate Registrar shall furnish or cause to be furnished to
the Servicer and the Depositor, or to the Indenture Trustee or the Owner
Trustee, within fifteen (15) days after receipt by the Certificate Registrar of
a written request therefor from the Servicer, the Depositor or the

                                       11

<PAGE>

Indenture Trustee or the Owner Trustee, as the case may be, a list, in such form
as the requesting party may reasonably require, of the names and addresses of
the Certificateholders as of the most recent Record Date. If three or more
Certificateholders or one or more Holders of Certificates evidencing not less
than 25% of the aggregate Certificate Percentage Interest apply in writing to
the Certificate Registrar, and such application states that the applicants
desire to communicate with other Certificateholders with respect to their rights
under this Agreement or under the Certificates and such application is
accompanied by a copy of the communication that such applicants propose to
transmit, then the Certificate Registrar shall, within five (5) Business Days
after the receipt of such application, afford such applicants access during
normal business hours to the current list of Certificateholders. Each
Certificateholder, by receiving and holding a Certificate, shall be deemed to
have agreed not to hold any of the Depositor, the Certificate Registrar or the
Owner Trustee accountable by reason of the disclosure of its name and address,
regardless of the source from which such information was derived.

          SECTION 3.8   Maintenance of Office or Agency. The Certificate
Registrar shall maintain in the Borough of Manhattan, The City of New York, an
office or offices or agency or agencies where Certificates may be surrendered
for registration of Transfer or exchange and where notices and demands to or
upon the Certificate Registrar in respect of the Certificates and the
Transaction Documents may be served. The Certificate Registrar shall give prompt
written notice to the Depositor, the Owner Trustee and the Certificateholders of
any change in the location of the Certificate Registrar or any such office or
agency.

          SECTION 3.9   Appointment of Paying Agent. The Paying Agent shall
make distributions to Certificateholders from the Certificate Payment Account
pursuant to Section 5.2 and shall report the amounts of such distributions to
the Owner Trustee. Any Paying Agent shall have the revocable power to withdraw
funds from the Certificate Payment Account for the purpose of making the
distributions referred to above. The Owner Trustee may revoke such power and
remove the Paying Agent if the Owner Trustee determines in its sole discretion
that the Paying Agent shall have failed to perform its obligations under this
Agreement in any material respect. The Paying Agent shall initially be the Owner
Trustee and any co-paying agent chosen by the Owner Trustee. The Owner Trustee
shall be permitted to resign as Paying Agent upon thirty (30) days' written
notice to the Depositor. In the event that the Owner Trustee shall no longer be
the Paying Agent, the Owner Trustee, upon receipt of written instructions from
the Depositor, shall appoint a successor to act as Paying Agent (which shall be
a bank or trust company). The Owner Trustee shall direct such successor Paying
Agent or any additional Paying Agent appointed by the Owner Trustee to execute
and deliver to the Owner Trustee an instrument in which such successor Paying
Agent or additional Paying Agent shall agree with the Owner Trustee that as
Paying Agent, such successor Paying Agent or additional Paying Agent will hold
all sums, if any, held by it for payment to the Certificateholders in trust for
the benefit of the Certificateholders entitled thereto until such sums shall be
paid to such Certificateholders. The Paying Agent shall return all unclaimed
funds to the Owner Trustee and upon removal of a Paying Agent such Paying Agent
shall also return all funds in its possession to the Owner Trustee. The
provisions of Sections 7.1, 7.3 and 8.1 shall apply to the Owner Trustee also in
its role as Paying Agent, for so long as the Owner Trustee shall act as Paying
Agent and, to the extent applicable, to any other paying agent appointed
hereunder. Any reference in this Agreement to the Paying Agent shall include any
co-paying agent unless the context requires otherwise.

                            ACTIONS BY OWNER TRUSTEE

          SECTION 4.1   Prior Notice to Certificateholders with Respect to
Certain Matters. With respect to the following matters, the Owner Trustee shall
not take action unless (i) at least thirty (30) days before the taking of such
action, the Owner Trustee shall have notified the Certificateholders and the
Rating Agencies in writing of the proposed action and (ii) the Holders of
Certificates evidencing not less than 51% of the aggregate Certificate
Percentage Interest shall not have notified the Owner Trustee in writing prior
to the 30th day after such notice is given that the Holders have withheld
consent or provided alternative direction:

               (i)   the initiation of any claim or lawsuit by the Trust (except
     claims or lawsuits brought by the Servicer in connection with the
     collection of the Receivables) and the settlement of any action,
     proceeding, investigation, claim or lawsuit brought by or against the Trust
     (except with respect to the aforementioned claims or lawsuits for
     collection by the Servicer of the Receivables);

               (ii)  the election by the Trust to file an amendment to the
     Certificate of Trust (unless such amendment is required to be filed under
     the Statutory Trust Statute);

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

               (iv)  the amendment of the Indenture by a supplemental indenture
     in circumstances where the consent of any Noteholder is not required and
     such amendment materially adversely affects the interests of the
     Certificateholders;

               (v)   the amendment, change or modification of the Sale and
     Servicing Agreement or the Administration Agreement, except to cure any
     ambiguity or to amend or supplement any provision in a manner or add any
     provision that would not materially adversely affect the interests of the
     Certificateholders; or

               (vi)  the appointment pursuant to the Indenture of a successor
     Note Registrar, Paying Agent for the Notes or Indenture Trustee or pursuant
     to this Agreement of a successor Certificate Registrar, or the consent to
     the assignment by the Note Registrar, Paying Agent for the Notes or
     Indenture Trustee or Certificate Registrar of its obligations under the
     Indenture or this Agreement, as applicable.

          SECTION 4.2   Action by Certificateholders with Respect to Certain
Matters. The Owner Trustee may not, except upon the occurrence of an Event of
Servicing Termination subsequent to the payment in full of the Notes and in
accordance with the written direction of the Holders of Certificates evidencing
not less than 51% of the aggregate Certificate Percentage Interest, (i) remove
the Servicer pursuant to Article VIII of the Sale and Servicing Agreement, (ii)
appoint a successor Servicer pursuant to Article VIII of the Sale and Servicing
Agreement, (iii) remove the Administrator pursuant to Section 9 of the
Administration Agreement, (iv) appoint a successor Administrator pursuant to

termination of the Indenture, except as expressly provided in the Transaction
Documents.

<PAGE>

          SECTION 4.3   Action by Certificateholders with Respect to Bankruptcy.
The Owner Trustee shall not have the power to commence a voluntary proceeding in
bankruptcy relating to the Trust unless (i) the Notes have been paid in full and
(ii) each Certificateholder approves of such commencement in writing in advance
and delivers to the Owner Trustee a certificate certifying that such Person
reasonably believes that the Trust is insolvent.

          SECTION 4.4   Restrictions on Certificateholders' Power. The
Certificateholders shall not direct the Owner Trustee to take or refrain from
taking any action if such action or inaction would be contrary to any obligation
of the Trust or the Owner Trustee under this Agreement or any of the other
Transaction Documents or would be contrary to Section 2.3, nor shall the Owner
Trustee be obligated to follow any such direction, if given.

          SECTION 4.5   Majority Control. Except as expressly provided herein,
any action that may be taken by the Certificateholders under this Agreement may
be taken by the Holders of Certificates evidencing not less than 51% of the
aggregate Certificate Percentage Interest. Except as expressly provided herein,
any written notice of the Certificateholders delivered pursuant to this
Agreement shall be effective if signed by the Holders of Certificates evidencing

          SECTION 4.6   Certain Litigation Matters. The Owner Trustee shall
provide prompt written notice to the Depositor, the Seller and the Servicer of
any action, proceeding or investigation known to the Owner Trustee that could
reasonably be expected to adversely affect the Trust or the Owner Trust Estate.

                                    ARTICLE V
                   APPLICATION OF TRUST FUNDS; CERTAIN DUTIES

          SECTION 5.1   Establishment of Certificate Payment Account. Pursuant
to Section 4.1(c) of the Sale and Servicing Agreement, the Servicer has agreed
to establish, on or before the Closing Date, and maintain in the name of the
Owner Trustee at an Eligible Institution (which shall initially be the Owner
Trustee) a segregated trust account designated as the "CarMax Auto Owner Trust
20[__]-[__] Trust Account" (the "Certificate Payment Account"). The Certificate
Payment Account shall be held in trust for the benefit of the
Certificateholders. Except as expressly provided in Section 3.9, the Certificate
Payment Account shall be under the sole dominion and control of the Owner
Trustee. All monies deposited from time to time in the Certificate Payment
Account pursuant to the Sale and Servicing Agreement or the Indenture shall be
applied as provided in this Agreement, the Sale and Servicing Agreement and the
Indenture.

          SECTION 5.2   Application of Trust Funds.

          (a)  On each Distribution Date, upon receipt of written instructions
from the Servicer pursuant to Section 4.9 of the Sale and Servicing Agreement,
the Owner Trustee shall, or, if the Owner Trustee is not the Paying Agent, shall
direct the Paying Agent to, distribute to the Certificateholders, in proportion
to each Certificateholder's Certificate Percentage Interest, amounts deposited
in the Certificate Payment Account on such Distribution Date pursuant to

                                       14

<PAGE>

Section 4.7 of the Sale and Servicing Agreement and Section 2.8 of the Indenture
with respect to such Distribution Date.

          (b)  On each Distribution Date, the Owner Trustee shall, or, if the
Owner Trustee is not the Paying Agent, the Owner Trustee shall direct the Paying
Agent to, send to each Certificateholder the statement provided to the Owner
Trustee by the Servicer pursuant to Section 4.9 of the Sale and Servicing
Agreement with respect to such Distribution Date.

          (c)  In the event that any withholding tax is imposed on any Trust
payment (or any allocation of income) to a Certificateholder, such tax shall
reduce the amount otherwise distributable to the Certificateholder in accordance
with this Section 5.2. The Owner Trustee and each Paying Agent are hereby
authorized and directed to retain from amounts otherwise distributable to the
Certificateholders sufficient funds for the payment of any such withholding tax
that is legally owed by the Trust (but such authorization shall not prevent the
Owner Trustee from contesting any such tax in appropriate proceedings, and
withholding payment of such tax, if permitted by law, pending the outcome of
such proceedings). The amount of any withholding tax imposed with respect to a
Certificateholder shall be treated as cash distributed to such Certificateholder
at the time it is withheld by the Trust and remitted to the appropriate taxing
authority. If there is a possibility that withholding tax is payable with
respect to a distribution (such as a distribution to a non-U.S.
Certificateholder), the Owner Trustee may withhold such amounts in accordance
with this Section 5.2. If a Certificateholder wishes to apply for a refund of
any such withholding tax, the Owner Trustee shall reasonably cooperate with such
Certificateholder in making such claim so long as such Certificateholder agrees
to reimburse the Owner Trustee for any out-of-pocket expenses incurred.

          SECTION 5.3   Method of Payment. Subject to Section 9.1(c),
distributions required to be made to Certificateholders on any Distribution Date
shall be made to each Certificateholder of record on the preceding Record Date
either by wire transfer, in immediately available funds, to the account of such
Holder at a bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided to the Certificate Registrar and the
Paying Agent appropriate written instructions at least five (5) Business Days
prior to such Distribution Date and such Certificateholder is the Seller or, if
not, by check mailed to such Certificateholder at the address of such Holder
appearing in the Certificate Register. Notwithstanding the foregoing, the final
distribution in respect of any Certificate (whether on the Final Distribution
Date or otherwise) will be payable only upon presentation and surrender of such
Certificate at the office or agency maintained for that purpose by the
Certificate Registrar pursuant to Section 3.8.

          SECTION 5.4   No Segregation of Monies; No Interest. Subject to
Sections 5.1 and 5.2, monies received by the Owner Trustee hereunder need not be
segregated in any manner except to the extent required by law, the Indenture or
the Sale and Servicing Agreement and may be deposited under such general
conditions as may be prescribed by law, and the Owner Trustee shall not be
liable for any interest thereon.

          SECTION 5.5   Accounting and Reports to the Noteholders,
Certificateholders, the Internal Revenue Service and Others. The Owner Trustee
shall, based on information provided by the Seller, (i) maintain (or cause to be
maintained) the books of the Trust on the basis of a fiscal year ending December
31, and based on the accrual method of accounting, (ii) deliver to each
Certificateholder, as may be required by the Code and applicable Treasury
Regulations, such information as may be required (including Schedule K-1) to
enable such Certificateholder to prepare its federal and state income tax
returns, (iii) file such tax returns relating to the Trust (including a
partnership information return, IRS Form 1065) and make such elections as may
from time to time be required or appropriate under any applicable state or
federal statute or rule or regulation thereunder so as to maintain the Trust's
characterization as a partnership for federal income tax purposes, (iv) cause
such tax returns to be signed in the manner required by law and (v) collect or
cause to be collected any withholding tax as described in and in accordance with
Section 5.2(c) with respect to income or distributions to Certificateholders.
The Owner Trustee, on behalf of the Trust, shall elect under Section 1278 of the
Code to include in income currently any market discount that accrues with
respect to the Receivables. The Owner Trustee, on behalf of the Trust, shall not
make the election provided under Section 754 of the Code.

          The Owner Trustee may satisfy its obligations with respect to this
Section 5.5 by retaining, at the expense of the Seller, a firm of independent
public accountants (the "Accountants") selected by the Seller. The Owner Trustee
may require the Accountants to provide to the Owner Trustee, on or before March
15, 20[__], a letter in form and substance satisfactory to the Owner Trustee as
to whether any federal tax withholding on Certificates is then required and, if
required, the procedures to be followed with respect thereto to comply with the
requirements of the Code. The Accountants shall be required to update such
letter in each instance that any additional tax withholding is subsequently
required or any previously required tax withholding shall no longer be required.
The Owner Trustee shall be deemed to have discharged its obligations pursuant to
this Section 5.5 upon its retention of the Accountants, and the Owner Trustee
shall not have any liability with respect to the default or misconduct of the
Accountants.

          SECTION 5.6   Signature on Returns; Tax Matters Partner.

returns of the Trust.

          (b)  The Seller, as a Certificateholder, shall be designated the "tax
matters partner" of the Trust pursuant to Section 6231(a)(7)(A) of the Code and
applicable Treasury Regulations.

                      AUTHORITY AND DUTIES OF OWNER TRUSTEE

          SECTION 6.1   General Authority. The Owner Trustee is authorized and
directed to execute and deliver the Transaction Documents to which the Trust is
to be a party and each certificate or other document attached as an exhibit to
or contemplated by the Transaction Documents to which the Trust is to be a
party, in each case in such form as the Depositor shall

                                       16

<PAGE>

approve, as evidenced conclusively by the Owner Trustee's execution thereof and
the Depositor's execution of this Agreement, and to direct the Indenture Trustee

amount of Class A-1 Notes, $[_______________] in aggregate principal amount of
Class A-2 Notes, $[_______________] in aggregate principal amount of Class A-3
Notes, $[_______________] in aggregate principal amount of Class A-4 Notes,
$[_______________] in aggregate principal amount of Class B Notes and
$[_______________] in aggregate principal amount of Class C Notes). In addition
to the foregoing, the Owner Trustee is authorized to take all actions required
of the Trust pursuant to the Transaction Documents. The Owner Trustee is further
authorized from time to time to take such action on behalf of the Trust as is
permitted by the Transaction Documents and which the Certificateholders, the
Servicer or the Administrator recommends in writing with respect to the
Transaction Documents, except to the extent that this Agreement expressly
requires the consent of Certificateholders for such action.

          SECTION 6.2   General Duties. It shall be the duty of the Owner
Trustee to discharge (or cause to be discharged) all of its responsibilities
pursuant to the terms of this Agreement and to administer the Trust for the
benefit of the Certificateholders, subject to the lien of the Indenture and in
accordance with the provisions of this Agreement. Notwithstanding the foregoing,
the Owner Trustee shall be deemed to have discharged (or caused to be
discharged) its duties and responsibilities hereunder to the extent the
Administrator is required in the Administration Agreement to perform any act or
to discharge such duty of the Owner Trustee or the Trust hereunder or under any
other Transaction Document, and the Owner Trustee shall not be held liable for
the default or failure of the Administrator to carry out its obligations under
the Administration Agreement.

          SECTION 6.3   Action upon Instruction.

          (a)  Subject to Article IV, and in accordance with the terms of the
Transaction Documents, the Certificateholders may, by written instruction,
direct the Owner Trustee in the management of the Trust.

          (b)  The Owner Trustee shall not be required to take any action under
this Agreement or any other Transaction Document if the Owner Trustee shall have
reasonably determined, or shall have been advised by counsel, that such action
is likely to result in liability on the part of the Owner Trustee or is contrary
to the terms of this Agreement or any other Transaction Document or is otherwise
contrary to law.

          (c)  Subject to Article IV, whenever the Owner Trustee is unable to
decide between alternative courses of action permitted or required by the terms
of this Agreement or any other Transaction Document, the Owner Trustee shall
promptly give notice (in such form as shall be appropriate under the
circumstances) to the Certificateholders requesting instruction as to the course
of action to be adopted, and to the extent the Owner Trustee acts in good faith
in accordance with any written instruction of the Certificateholders received,
the Owner Trustee shall not be liable on account of such action to any Person.
If the Owner Trustee shall not have received appropriate written instruction
within ten (10) days of such notice (or within such shorter period of time as
reasonably may be specified in such notice or may be necessary under

                                       17

<PAGE>

the circumstances) it may, but shall be under no duty to, take or refrain from
taking such action, not inconsistent with this Agreement or the other
Transaction Documents, as it shall deem to be in the best interests of the
Certificateholders, and shall have no liability to any Person for such action or
inaction.

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

          SECTION 6.4   No Duties Except as Specified in this Agreement or in
Instructions. The Owner Trustee shall not have any duty or obligation to manage,
make any payment with respect to, register, record, sell, dispose of or
otherwise deal with the Owner Trust Estate, or to otherwise take or refrain from
taking any action under, or in connection with, any document contemplated hereby
to which the Owner Trustee or the Trust is a party, except as expressly provided
by the terms of this Agreement or in any document or written instruction
received by the Owner Trustee pursuant to Section 6.3, and no implied duties or
obligations shall be read into this Agreement or any other Transaction Document
against the Owner Trustee. The Owner Trustee shall have no responsibility for
filing any financing or continuation statement in any public office at any time
or otherwise to perfect or maintain the perfection of any security interest or
lien granted to it hereunder or to prepare or file any Commission filing for the
Trust or to record this Agreement or any other Transaction Document. The Owner
Trustee shall, however, at its own cost and expense, promptly take all action as
may be necessary to discharge any lien (other than the lien of the Indenture) on
any part of the Owner Trust Estate that results from actions by, or claims
against, the Owner Trustee in its individual capacity that are not related to
the ownership or the administration of the Owner Trust Estate.

          SECTION 6.5   No Action Except Under Specified Documents or
Instructions. The Owner Trustee shall not manage, control, use, sell, dispose of
or otherwise deal with any part of the Owner Trust Estate except (i) in
accordance with the powers granted to and the authority conferred upon the Owner
Trustee pursuant to this Agreement, (ii) in accordance with the other
Transaction Documents to which the Trust is a party and (iii) in accordance with
any document or written instruction delivered to the Owner Trustee pursuant to
Section 6.3.

          SECTION 6.6   Restrictions. The Owner Trustee shall not take any
action (i) that is inconsistent with the purposes of the Trust set forth in
Section 2.3 or (ii) that, to the actual

                                       18

<PAGE>

knowledge of the Owner Trustee, would (A) affect the treatment of the Notes as
indebtedness for federal income or Virginia income or franchise tax purposes,
(B) be deemed to cause a taxable exchange of the Notes for federal income or
Virginia income or franchise tax purposes or (C) cause the Trust or any portion
thereof to be taxable as an association or publicly traded partnership taxable
as a corporation for federal income or Virginia income or franchise tax
purposes. The Certificateholders, the Administrator and the Servicer shall not
direct the Owner Trustee to take action that would violate the provisions of
this Section 6.6.

     or the Servicer;

     otherwise incur financial liability in the performance of any of its duties
     hereunder or in the exercise of any of its rights or powers hereunder or
     under any other Transaction Document if the Owner Trustee shall have
     reasonable grounds to believe that repayment of such funds or adequate
     indemnity against such risk or liability is not reasonably assured or

     discretionary act enumerated in this Agreement or any other Transaction
     Document shall not be construed as a duty, and the Owner Trustee shall not
     be answerable other than for its willful misconduct, bad faith or

to the Certificateholders promptly upon receipt of a written request therefor,

any other instruments furnished to the Owner Trustee under the Transaction
Documents.

          SECTION 7.3   Representations and Warranties.

          (a)  [RESERVED].

          (b)  The Owner Trustee, in its individual capacity, hereby represents

               (i)    it is a [____________________] duly organized and validly
     existing in good standing under the laws of [____________________] and has
     all requisite power and authority to execute, deliver and perform its
     obligations under this Agreement;

               (ii)   it has taken all action necessary to authorize the
     execution and delivery by it of this Agreement, and this Agreement will be
     executed and delivered by one of its officers who is duly authorized to

               (iii)  neither the execution nor the delivery by it of this
     Agreement, nor the consummation by it of the transactions contemplated
     hereby nor compliance by it with any of the terms or provisions hereof will
     contravene any federal or [____________________] law, governmental rule or
     regulation governing the banking or trust powers of the Owner Trustee or
     any judgment or order binding on it, or constitute any default under its
     charter documents or by-laws or any indenture, mortgage, contract,

not specifically prescribed herein, the Owner Trustee may for all purposes
hereof rely on a certificate, signed by the president or any vice president or
by the treasurer or other authorized officers of the relevant party, as to such
fact or matter and such certificate shall constitute full protection to the

                                       21

accountants and other skilled Persons to be selected with reasonable care and
employed by it. The Owner Trustee shall not be liable for anything done,
suffered or omitted in good faith by it in accordance with the written opinion
or advice of any such counsel, accountants or other such Persons and not
contrary to this Agreement or any other Transaction Document.

          SECTION 7.5   Not Acting in Individual Capacity. Except as provided in
Section 7.3, in accepting the trusts hereby created, [____________________] acts
solely as Owner Trustee hereunder and not in its individual capacity, and all

no responsibility for the correctness thereof. The Owner Trustee makes no
representations as to the validity or sufficiency of this Agreement, any other
Transaction Document, the Certificates (other than the signature and
countersignature of the Owner Trustee on the Certificates) or the Notes, or of
any Receivable or related documents. The Owner Trustee shall at no time have any
responsibility or liability for or with respect to the legality, validity and
enforceability of any Receivable, or the perfection and priority of any security
interest created by any Receivable in any Financed Vehicle or the maintenance of
any such perfection and priority, or for or with respect to the sufficiency of
the Owner Trust Estate or its ability to generate the payments to be distributed
to the Certificateholders under this Agreement or to the Noteholders under the
Indenture, including, without limitation, the existence, condition and ownership
of any Financed Vehicle, the existence and enforceability of any insurance
thereon, the existence and contents of any Receivable on any computer or other
record thereof, the validity of the assignment of any Receivable to the Trust or
any intervening assignment, the completeness of any Receivable, the performance
or enforcement of any Receivable, the compliance by the Depositor or the
Servicer with any warranty or representation made under any Transaction Document
or in any related document, or the accuracy of any such warranty or
representation or any action of the Indenture Trustee, the Administrator or the
Servicer taken in the name of the Owner Trustee.

          SECTION 7.7   Owner Trustee May Own Certificates and Notes. The Owner
Trustee, in its individual or any other capacity, may become the owner or
pledgee of Certificates or Notes and may deal with the Depositor, the Servicer,
the Administrator and the Indenture Trustee in banking transactions with the

                                  ARTICLE VIII
                COMPENSATION AND INDEMNIFICATION OF OWNER TRUSTEE

          SECTION 8.1   Owner Trustee's Fees and Expenses. The Owner Trustee
shall receive as compensation for its services hereunder such fees as have been
separately agreed upon before the date hereof between the Servicer and the Owner
Trustee, and the Owner Trustee shall be reimbursed by the Servicer for its other
reasonable expenses hereunder, including the

                                       22

<PAGE>

reasonable compensation, expenses and disbursements of such agents,
representatives, experts and counsel as the Owner Trustee may employ in
connection with the exercise and performance of its rights and its duties
hereunder.

          SECTION 8.2   Indemnification. To the fullest extent permitted by
applicable law, the initial Servicer shall be liable as prime obligor for, and
shall indemnify the Owner Trustee and its successors, assigns, agents and
servants (collectively, the "Indemnified Parties") from and against, any and all
liabilities, obligations, losses, damages, taxes, claims, actions and suits, and
any and all reasonable costs, expenses and disbursements (including reasonable
legal fees and expenses) of any kind and nature whatsoever (collectively,
"Expenses") which may at any time be imposed on, incurred by, or asserted
against the Owner Trustee or any other Indemnified Party in any way relating to
or arising out of this Agreement, the other Transaction Documents, the Owner
Trust Estate, the administration of the Owner Trust Estate or the action or
inaction of the Owner Trustee hereunder; provided, however, that the initial
Servicer shall not be liable for or required to indemnify an Indemnified Party
from and against Expenses arising or resulting from any of the matters described
in the third sentence of Section 7.1. In no event will the initial Servicer or
the Owner Trustee be entitled to make any claim upon the Owner Trust Estate for
the payment or reimbursement of any Expenses. The indemnities contained in this
Section 8.2 shall survive the resignation or termination of the Owner Trustee or
the termination of this Agreement. In the event of any claim, action or
proceeding for which indemnity will be sought pursuant to this Section 8.2, the
Owner Trustee's choice of legal counsel shall be subject to the approval of the
initial Servicer, which approval shall not be unreasonably withheld.

          SECTION 8.3   Payments to the Owner Trustee. Any amounts paid to the
Owner Trustee pursuant to this Article VIII shall be deemed not to be a part of
the Owner Trust Estate immediately after such payment.

                                   ARTICLE IX
                                   TERMINATION

          SECTION 9.1   Termination of Trust Agreement.

          (a)  This Agreement (other than the provisions of Article VIII) shall
terminate and be of no further force or effect and the Trust shall dissolve upon
the earlier of (i) the payment to the Servicer, the Noteholders and the
Certificateholders of all amounts required to be paid to them pursuant to the
terms of the Indenture, the Sale and Servicing Agreement and Article V and (ii)
the Distribution Date next succeeding the month which is one year after the
maturity or other liquidation of the last Receivable and the disposition of any
amounts received upon liquidation of any property remaining in the Trust. The
bankruptcy, liquidation, dissolution, death or incapacity of any
Certificateholder shall not operate to terminate this Agreement or the Trust,
entitle such Certificateholder's legal representatives or heirs to claim an
accounting or to take any action or proceeding in any court for a partition or
winding up of all or any part of the Trust or Owner Trust Estate or otherwise
affect the rights, obligations and liabilities of the parties hereto.

          (b)  No Certificateholder shall be entitled to revoke or terminate the
Trust.

                                       23

<PAGE>

          (c)  Notice of any termination of the Trust, specifying the
Distribution Date upon which the Certificateholders shall surrender their
Certificates to the Paying Agent for payment of the final distribution and
cancellation, shall be given by the Owner Trustee by letter to
Certificateholders mailed within five (5) Business Days of receipt of notice of
such termination from the Servicer, stating (i) the Distribution Date upon or
with respect to which final payment of the Certificates shall be made upon
presentation and surrender of the Certificates at the office of the Paying Agent
therein specified, (ii) the amount of any such final payment and (iii) that the
Record Date otherwise applicable to such Distribution Date is not applicable,
payments being made only upon presentation and surrender of the Certificates at
the office of the Paying Agent therein specified. The Owner Trustee shall give
such notice to the Certificate Registrar (if other than the Owner Trustee) and
the Paying Agent at the time such notice is given to Certificateholders. Upon
presentation and surrender of the Certificates, the Paying Agent shall cause to
be distributed to the Certificateholders, subject to Section 3808 of the
Statutory Trust Statute, amounts distributable on such Distribution Date
pursuant to Section 5.2. In the event that all of the Certificateholders shall
not surrender their Certificates for cancellation within six (6) months after
the date specified in the above mentioned written notice, the Owner Trustee
shall give a second written notice to the remaining Certificateholders to
surrender their Certificates for cancellation and receive the final distribution
with respect thereto. If within one year after the second notice all the
Certificates shall not have been surrendered for cancellation, the Owner Trustee
may take appropriate steps, or may appoint an agent to take appropriate steps,
to contact the remaining Certificateholders concerning surrender of their
Certificates and the cost thereof shall be paid out of the funds and other
assets that shall remain subject to this Agreement. Subject to applicable
escheat laws, any funds remaining in the Trust after exhaustion of such remedies
shall be distributed by the Owner Trustee to the Certificateholders in
proportion to each Certificateholder's Certificate Percentage Interest.

          (d)  Upon the winding up of the Trust, in accordance with Section 3808
of the Statutory Trust Statute, and its termination, the Owner Trustee shall
cause the Certificate of Trust to be canceled by filing a certificate of
cancellation with the Secretary of State in accordance with the provisions of
Section 3810 of the Statutory Trust Statute.

such corporation or banking association shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Owner Trustee shall cease to be eligible in
accordance with the provisions of

                                       24

<PAGE>

this Section 10.1, the Owner Trustee shall resign immediately in the manner and
with the effect specified in Section 10.2.

          SECTION 10.2  Resignation or Removal of Owner Trustee. The Owner
Trustee may at any time resign and be discharged from the trusts hereby created
by giving written notice thereof to the Administrator and the Depositor. Upon
receiving such notice of resignation, the Administrator shall promptly appoint a
successor Owner Trustee (acceptable to the Depositor) by written instrument, in
duplicate, one copy of which instrument shall be delivered to the resigning
Owner Trustee and one copy to the successor Owner Trustee. If no successor Owner
Trustee shall have been so appointed and have accepted appointment within thirty
(30) days after the giving of such notice of resignation, the resigning Owner
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Owner Trustee.

          If at any time the Owner Trustee shall cease to be eligible in
accordance with the provisions of Section 10.1 and shall fail to resign after
written request therefor by the Administrator, or if at any time the Owner
Trustee shall be legally unable to act, or shall be adjudged bankrupt or
insolvent, or a receiver of the Owner Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Owner
Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, or the Owner Trustee shall otherwise become
incapable of acting, then the Administrator may remove the Owner Trustee. If the
Administrator shall remove the Owner Trustee under the authority of the
immediately preceding sentence, the Administrator shall promptly appoint a
successor Owner Trustee (acceptable to the Depositor) by written instrument, in
duplicate, one copy of which instrument shall be delivered to the removed Owner
Trustee and one copy to the successor Owner Trustee.

          Any resignation or removal of the Owner Trustee and appointment of a
successor Owner Trustee pursuant to this Section 10.2 shall not become effective
until acceptance of appointment by the successor Owner Trustee pursuant to
Section 10.3 and payment of all fees and expenses owed to the outgoing Owner
Trustee. The Administrator shall provide notice of such resignation or removal
of the Owner Trustee to the Depositor, the Certificateholders, the Indenture
Trustee, the Noteholders and the Rating Agencies.

          SECTION 10.3  Successor Owner Trustee. Any successor Owner Trustee
appointed pursuant to Section 10.2 shall execute, acknowledge and deliver to the
Administrator and to its predecessor Owner Trustee an instrument accepting such
appointment under this Agreement, and thereupon, subject to the payment of all
fees and expenses owed to the predecessor Owner Trustee, the resignation or
removal of the predecessor Owner Trustee shall become effective and such
successor Owner Trustee, without any further act, deed or conveyance, shall
become fully vested with all the rights, powers, duties and obligations of its
predecessor under this Agreement, with like effect as if originally named as
Owner Trustee. The predecessor Owner Trustee shall, upon payment of its fees and
expenses, deliver to the successor Owner Trustee all documents, statements and
monies held by it under this Agreement, and the Administrator and the
predecessor Owner Trustee shall execute and deliver such instruments and do such
other things as may reasonably be required for fully and certainly vesting and
confirming in the successor Owner Trustee all such rights, powers, duties and
obligations.

                                       25

<PAGE>

          No successor Owner Trustee shall accept appointment as provided in
this Section 10.3 unless, at the time of such acceptance, such successor Owner
Trustee shall be eligible pursuant to Section 10.1.

          Any successor Owner Trustee appointed pursuant to this Section 10.3
shall file an amendment to the Certificate of Trust with the Secretary of State
reflecting the name and principal place of business of such successor in the
State of Delaware.

          Upon acceptance of appointment by a successor Owner Trustee pursuant
to this Section 10.3, the Administrator shall mail notice of such appointment to
all Certificateholders, the Indenture Trustee, the Noteholders and the Rating
Agencies. If the Administrator shall fail to mail such notice within ten (10)
days after acceptance of appointment by the successor Owner Trustee, the
successor Owner Trustee shall cause such notice to be mailed at the expense of
the Administrator.

          SECTION 10.4  Merger or Consolidation of Owner Trustee.

          (a)  If the Owner Trustee consolidates with, merges or converts into,
or transfers all or substantially all its corporate trust business or assets to,
another corporation or banking association, the resulting, surviving or
transferee corporation or banking association without any further act, except
the filing of an amendment to the Certificate of Trust, if required under the
Statutory Trust Statute, shall be the successor Owner Trustee; provided,
however, that such corporation or banking association must be otherwise
qualified and eligible under Section 10.1. The Owner Trustee shall provide the
Rating Agencies with prior written notice of any such transaction.

          (b)  If at the time such successor or successors by consolidation,
merger or conversion to the Owner Trustee shall succeed to the trusts created by
this Agreement any of the Certificates shall have been authenticated but not
delivered, any such successor to the Owner Trustee may adopt the certificate of
authentication of any predecessor trustee and deliver such Certificates so
authenticated, and in case at that time any of the Certificates shall not have
been authenticated, any such successor to the Owner Trustee may authenticate
such Certificates either in the name of any predecessor trustee or in the name
of the successor to the Owner Trustee. In all such cases such certificates shall
have the full force which the Certificates or this Agreement provide that the
certificate of the Owner Trustee shall have.

          SECTION 10.5  Appointment of Co-Trustee or Separate Trustee.

          (a)  Notwithstanding any other provisions of this Agreement to the
contrary, at any time, for the purpose of meeting any legal requirement of any
jurisdiction in which any part of the Owner Trust Estate or any Financed Vehicle
may at the time be located, the Administrator and the Owner Trustee acting
jointly shall have the power and may execute and deliver an instrument to
appoint one or more Persons approved by the Owner Trustee to act as co-trustee
or co-trustees, jointly with the Owner Trustee, or separate trustee or separate
trustees, of all or any part of the Owner Trust Estate, and to vest in such
Person or Persons, in such capacity and for the benefit of the
Certificateholders, such title to the Owner Trust Estate, or any part thereof,
and, subject to the other provisions of this Section 10.5, such powers, duties,
obligations, rights and

                                       26

<PAGE>

trusts as the Administrator and the Owner Trustee may consider necessary or
desirable. If the Administrator shall not have joined in such appointment within
fifteen (15) days after the receipt by it of a request so to do, the Owner
Trustee alone shall have the power to make such appointment. No co-trustee or
separate trustee under this Agreement shall be required to meet the terms of
eligibility as a successor trustee under Section 10.1 and no notice of the
appointment of any co-trustee or separate trustee shall be required under
Section 10.3.

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

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

               (ii)  no trustee under this Agreement shall be personally liable
     by reason of any act or omission of any other trustee under this Agreement;
     and

               (iii) the Administrator and the Owner Trustee acting jointly may
     at any time accept the resignation of or remove any separate trustee or
     co-trustee.

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

          (d)  Any separate trustee or co-trustee may at any time constitute the
Owner Trustee its agent or attorney-in-fact with full power and authority, to
the extent permitted by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. If any separate trustee or co-trustee
shall die, become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Owner Trustee, to the extent permitted by law, without the appointment of a new
or successor trustee.

          SECTION 11.1  Supplements and Amendments.

          (a)  This Agreement may be amended from time to time by the Depositor
and the Owner Trustee with prior written notice to the Rating Agencies, without
the consent of any of the Noteholders or the Certificateholders to cure any
ambiguity, to correct or supplement any provision herein that may be
inconsistent with any other provision herein or in any offering document used in
connection with the initial offer and sale of the Notes or the Certificates or
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Agreement which will not be
inconsistent with other provisions of this Agreement; provided, however, that
(i) no such amendment may materially adversely affect the interests of any
Noteholder or Certificateholder and (ii) no such amendment will be permitted
unless an Opinion of Counsel is delivered to the Owner Trustee to the effect
that such amendment will not cause the Trust to be characterized for federal
income tax purposes as an association taxable as a corporation or otherwise have
any material adverse impact on the federal income taxation of any Notes
Outstanding or outstanding Certificates or any Noteholder or Certificateholder.

          (b)  This Agreement may be amended from time to time by the Depositor
and the Owner Trustee with prior written notice to the Rating Agencies, with the
consent of the Holders (as defined in the Indenture) of Notes evidencing not
less than 51% of the Note Balance or, if the Notes have been paid in full, the
Holders of Certificates evidencing not less than 51% of the aggregate
Certificate Percentage Interest, for the purpose of adding any provisions to, or
changing in any manner or eliminating any of the provisions of, this Agreement
or modifying in any manner the rights of the Noteholders or the
Certificateholders; provided, however, that (x) no such amendment will be
permitted unless an Opinion of Counsel is delivered to the Owner Trustee to the
effect that such amendment will not cause the Trust to be characterized for
federal income tax purposes as an association taxable as a corporation or
otherwise have any material adverse impact on the federal income taxation of any
Notes Outstanding or outstanding Certificates or any Noteholder or
Certificateholder and (y) no such amendment may:

               (i)   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 or in respect of the Receivables or
     distributions that are required to be made for the benefit of the
     Noteholders or the Certificateholders, or change any Note Rate, without the
     consent of all Noteholders and Certificateholders adversely affected by
     such amendment;

               (ii)  reduce the percentage of the Note Balance or the
     percentage of the aggregate Certificate Percentage Interest the consent of
     the Holders of which is required for any amendment to this Agreement
     without the consent of all the Noteholders and Certificateholders adversely
     affected by the amendment; or

               (iii) adversely affect the rating assigned by any Rating Agency
     to any Class of Notes without the consent of the Holders (as defined in the
     Indenture) of Notes

                                       28

<PAGE>

     evidencing not less than 66 2/3% of the aggregate principal amount of the
     then outstanding Notes of such Class.

          (c)  An amendment to this Agreement shall be deemed not to materially
adversely affect the interests of any Noteholder or Certificateholder if (i) the
Person requesting such amendment obtains and delivers to the Owner Trustee an
Opinion of Counsel to that effect or (ii) the Rating Agency Condition is
satisfied.

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

          (e)  It shall not be necessary for the consent of the
Certificateholders, the Noteholders or the Indenture Trustee pursuant to this
Section 11.1 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
Certificateholders provided for in this Agreement or in any other Transaction
Document) and of evidencing the authorization of the execution thereof by
Certificateholders shall be subject to such reasonable requirements as the Owner
Trustee may prescribe.

          (f)  Promptly after the execution of any amendment to the Certificate
of Trust, the Owner Trustee shall file such amendment or cause such amendment to
be filed with the Secretary of State.

          (g)  The Owner Trustee may, but shall not be obligated to, enter into
any such amendment that affects the Owner Trustee's own rights, duties,
liabilities or immunities under this Agreement or otherwise.

          (h)  Prior to the execution of any amendment to this Agreement or any
amendment to any other agreement to which the Trust is a party, the Owner
Trustee shall be entitled to receive and shall be fully protected in relying
upon an Opinion of Counsel stating that the execution of such amendment is
authorized or permitted by this Agreement and that all conditions precedent in
this Agreement to the execution and delivery of such amendment have been
satisfied.

          SECTION 11.2  No Legal Title to Owner Trust Estate in
Certificateholders. The Certificateholders shall not have legal title to any
part of the Owner Trust Estate. The Certificateholders shall be entitled to
receive distributions with respect to their undivided beneficial interest
therein only in accordance with Articles V and IX. No transfer, by operation of
law or otherwise, of any right, title or interest of the Certificateholders in
and to their beneficial interest in the Owner Trust Estate shall operate to
terminate this Agreement or the trusts hereunder or entitle any transferee to an
accounting or to the transfer to it of legal title to any part of the Owner
Trust Estate.

presumed to have been duly given, whether or not the Certificateholder shall

action by a Certificateholder shall bind the successors and assigns of such
Certificateholder.

                            [REVERSE OF CERTIFICATE]

          This Certificate does not represent an obligation of, or an interest
in, the Depositor, the Seller, the Servicer, the Administrator, the Owner
Trustee or any Affiliates of any of them, and no recourse may be had against
such parties or their assets, except as may be expressly set forth or
contemplated herein, in the Trust Agreement or in the other Transaction
Documents. In addition, this Certificate is not guaranteed by any governmental
agency or instrumentality and is limited in right of payment to certain
collections with respect to the Receivables (and certain other amounts), all as
more specifically set forth herein and in the Sale and Servicing Agreement.

          The Trust Agreement permits the Depositor and the Owner Trustee, on
behalf of the Trust, with certain exceptions therein provided, to amend or waive
from time to time certain terms and conditions set forth in the Trust Agreement
without the consent of the Holders of the Certificates. The Trust Agreement also
permits the Depositor and the Owner Trustee, on behalf of the Trust, with
certain exceptions as therein provided, to amend or waive certain terms and
conditions set forth in the Trust Agreement with the consent of the Holders of
the Notes evidencing not less than 51% of the Note Balance and the Holders of
Certificates evidencing not less than 51% of the aggregate Certificate
Percentage Interest. Any such consent or waiver by the Holder of this
Certificate shall be conclusive and binding on such Holder and on all future
Holders of this Certificate and of any Certificate issued upon the registration
of transfer hereof or in exchange hereof or in lieu hereof whether or not
notation of such consent or waiver is made upon this Certificate.

          As provided in the Trust Agreement and subject to certain limitations
therein set forth, the Transfer of this Certificate may be registered in the
Certificate Register upon surrender of this Certificate for registration of
Transfer at the office or agency of the Certificate Registrar maintained for
that purpose in the Borough of Manhattan, The City of New York and a written
instrument of transfer in form satisfactory to the Certificate Registrar duly
executed by the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates in any authorized
denomination and in the same aggregate principal amount will be issued to the
designated transferee or transferees. No service charge shall be made for any
registration of Transfer or exchange of Certificates, but the Owner Trustee or
the Certificate Registrar may require payment of a sum sufficient to cover any
tax or governmental charge that may be imposed in connection therewith. The
initial Certificate Registrar appointed under the Trust Agreement is the
Indenture Trustee.

          Each Certificateholder, by its acceptance of a Certificate, shall be
deemed to have represented and warranted that such Certificateholder (A) is not
an employee benefit plan or arrangement subject to Section 406 of ERISA or a
plan subject to Section 4975 of the Code (a "Plan"), nor a person acting on
behalf of a Plan nor using the assets of a Plan to effect the transfer of such
Certificate, and (B) is not an insurance company purchasing a Certificate with
funds contained in an "insurance company general account" (as defined in Section
V(e) of Prohibited Transaction Class Exemption 95-60) that includes the assets
of a Plan for purposes of the Plan Asset Regulation.

                                      A-5

<PAGE>

          Any person who is not an affiliate of the Seller and acquires more
than 49.9% of the Certificates will be deemed to represent that it is not a
party in interest (within the meaning of ERISA) or a disqualified person (within
the meaning of Section 4975(e)(2) of the Code) with respect to any Plan, other
than a Plan that it sponsors for the benefit of its employees, and that no Plan
with respect to which it is a party in interest has or will acquire any interest
in the Notes.

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

          The Owner Trustee, the Certificate Registrar and any Paying Agent may
treat the Person in whose name this Certificate is registered in the Certificate
Register (as of the day of determination) as the owner of this Certificate for
the purpose of receiving distributions pursuant to the Trust Agreement and for
all other purposes whatsoever, and none of the Owner Trustee, the Certificate
Registrar or any Paying Agent shall be bound by any notice to the contrary.

          The Trust Agreement, with certain exceptions therein provided, and the
Trust shall terminate and be of no further force or effect upon the earlier of
(i) the payment to the Servicer, the Noteholders and the Certificateholders of
all amounts required to be paid to them pursuant to the terms of the Indenture,
the Sale and Servicing Agreement and the Trust Agreement and (ii) the
Distribution Date next succeeding the month which is one year after the maturity
or other liquidation of the last Receivable and the disposition of any amounts
received upon liquidation of any property remaining in the Trust.

          This Certificate shall be governed by, and construed in accordance
with, the laws of the State of Delaware, and the obligations, rights and
remedies of the parties hereunder shall be determined in accordance with such
laws.
