such Certificate a certificate of authentication substantially in the form set
forth in Exhibit A, executed by the Owner Trustee or The Chase Manhattan Bank,
         ---------
as the Owner Trustee's authenticating agent, by manual signature. Such

have been duly authenticated and delivered hereunder.  All Certificates shall be
dated the date of their authentication.

Reserve Account), provided that: (i) such action will not result in a reduction
or withdrawal of the rating of any class of Notes, (ii) the Certificateholders
provide to the Owner Trustee and the Indenture Trustee an opinion of independent
counsel that such action will not cause the Trust to be treated as an
association (or publicly traded partnership) taxable as a corporation for
Federal income tax purposes, (iii) such transferee or assignee agrees to take
positions for tax purposes consistent with the tax positions agreed to be taken
by the Certificateholders and (iv) the conditions set forth in Section 9.11 have
been satisfied.  In addition, no transfer of a Certificate shall be registered
unless the transferee shall have provided to the Owner Trustee and the
Certificate Registrar an opinion of counsel that in connection with such
transfer no registration of the Certificates is required under the Securities
Act or applicable state law or that such transfer is otherwise being made in
accordance with all applicable federal and state securities laws.

          (c) Subject to Section 3.4(b), upon surrender for registration of
transfer of any Certificate at the office or agency maintained pursuant to
Section 3.8, the Owner Trustee shall execute, authenticate and deliver (or shall
cause The Chase Manhattan Bank as its authenticating agent to authenticate and
deliver), in the name of the designated transferee or transferees, one or more
new Certificates in authorized denominations of a like aggregate amount dated
the date of authentication by the Owner Trustee or any authenticating agent.

          (d) At the option of a Holder, Certificates may be exchanged for other
Certificates of a like aggregate percentage interest upon surrender of the
Certificates to be exchanged at the Corporate Trust Office maintained pursuant
to Section 3.8.  Whenever any Certificates are so surrendered for exchange, the
Owner Trustee shall execute, authenticate and deliver (or shall cause The Chase
Manhattan Bank as its authenticating agent to authenticate and deliver) one or
more Certificates dated the date of authentication by the Owner Trustee or any
authenticating agent.  Such Certificates shall be delivered to the Holder making
the exchange.

          (e) Every Certificate presented or surrendered for registration of
transfer or exchange shall be accompanied by a written instrument of transfer in
form satisfactory to the Owner Trustee and the Certificate Registrar duly
executed by the Holder or his attorney duly authorized in writing.  Each
Certificate surrendered for registration of transfer or exchange shall be
canceled and subsequently destroyed or otherwise disposed of by the Owner
Trustee or Certificate Registrar in accordance with its customary practice.

          (f) 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.

                        -------------------------------------------------

          (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, the Owner Trustee such security or indemnity as
may be required by it to hold it harmless, then, in the absence of notice to the
Certificate Registrar or the Owner Trustee that such Certificate has been
acquired by a protected purchaser, the Owner Trustee shall execute and the Owner
Trustee shall authenticate and deliver (or shall cause The Chase Manhattan Bank
as its authenticating agent to authenticate and deliver), in exchange for or in
lieu of any such mutilated, destroyed, lost or stolen Certificate, a replacement
Certificate in authorized denominations of a like amount; provided, however,
                                                          --------  -------
that if any such destroyed, lost or stolen Certificate, but not a mutilated
Certificate, shall have become or within seven days shall be due and payable,
then instead of issuing a replacement Certificate the Owner Trustee may pay such
destroyed, lost or stolen Certificate when so due or payable.

          (b) If, after the delivery of a replacement Certificate or
distribution in respect of a destroyed, lost or stolen Certificate pursuant to
subsection 3.5(a), a bona fide purchaser of the original Certificate in lieu of
which such replacement Certificate was issued presents for payment such original
Certificate, the Owner Trustee shall be entitled to recover such replacement
Certificate (or such distribution) from the Person to whom it 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
bona fide purchaser, 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 Owner Trustee in connection therewith.

          (c) In connection with the issuance of any replacement Certificate
under this Section 3.5, the Owner Trustee 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 relation thereto and any other reasonable expenses
(including the fees and expenses of the Owner Trustee and the Certificate
Registrar) connected therewith.

          (d) Any duplicate 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 under this Agreement ,
whether or not the mutilated, destroyed, lost or stolen Certificate shall be
found at any time or be enforced 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.

          (e) 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 Certificateholders.  Prior to due
                        ---------------------------------
presentation of a Certificate for registration of transfer, the Owner Trustee or
the Certificate Registrar may treat the Person in whose name any Certificate
shall be registered in the Certificate Register as the

                                      -7-
<PAGE>

Certificateholder of such Certificate for the purpose of receiving distributions
pursuant to Article V and for all other purposes whatsoever, and neither the
Owner Trustee nor the Certificate Registrar shall be bound by any notice to the
contrary.

          SECTION 3.7   Access to List of Certificateholders' Names and
                        -----------------------------------------------
Addresses.  The Owner Trustee shall furnish or cause to be furnished to the
---------
Servicer and the Seller, within 15 days after receipt by the Owner Trustee of a
request therefor from the Servicer or the Seller in writing, a list, in such
form as the Servicer or the Seller may reasonably require, of the names and
addresses of the Certificateholders as of the most recent Record Date.  Each
Holder, by receiving and holding a Certificate, shall be deemed to have agreed
not to hold any of the Servicer, the Seller 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 Corporate Trust Office.  The Owner
                        -------------------------------------
Trustee 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 Owner Trustee in respect of the Certificates and the Basic Documents
may be served.  The Owner Trustee initially designates the offices of The Chase
Manhattan Bank, 55 Water Street, New York, New York, as its principal office for
such purposes. The Owner Trustee shall give prompt written notice to the Seller
and to the Certificateholders of any change in the location of the Certificate
Register or any such office or agency.

          SECTION 3.9   Appointment of Paying Agent.  The Paying Agent shall
                        ---------------------------
make distributions to Certificateholders from the Certificate Distribution
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 Distribution 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 Chase Manhattan Bank, and any co-paying agent chosen by
The Chase Manhattan Bank, and acceptable to the Owner Trustee.  The Chase
Manhattan Bank shall be permitted to resign as Paying Agent upon 30 days'
written notice to the Owner Trustee.  If The Chase Manhattan Bank shall no
longer be the Paying Agent, the Owner Trustee shall appoint a successor to act
as Paying Agent (which shall be a bank or trust company).  The Owner Trustee
shall cause 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 shall hold all sums, if any, held by it for distribution
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 6.3, 6.6, 6.7, 6.8
and 6.9 shall apply, mutatis mutandis, 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

                                      -8-

appointed hereunder. Any reference in this Agreement to the Paying Agent shall
include any co-paying agent unless the context requires otherwise.

                        ---------------------------
individual or any other capacity may become the owner or pledgee of Certificates
and may otherwise deal with the Owner Trustee or its Affiliates as if it were
not the Seller.

                        -----------------------------------------

                  APPLICATION OF TRUST FUNDS; CERTAIN DUTIES

          SECTION 5.1   Establishment of Certificate Distribution Account.
                        -------------------------------------------------

          (a)  The Servicer, for the benefit of the Certificateholders, shall
establish and maintain at The Chase Manhattan Bank in the name of the Owner
Trustee an Eligible Deposit Account known as the Navistar Financial 2001-A Owner
Trust Certificate Distribution Account (the "Certificate Distribution Account"),
bearing an additional designation clearly indicating that the funds deposited
therein are held for the benefit of the Certificateholders.

          (b)  The Owner Trustee shall possess all right, title and interest in
and to all funds on deposit from time to time in the Certificate Distribution
Account and in all proceeds thereof. Except as otherwise provided herein or in
the Pooling and Servicing Agreement, the Certificate Distribution Account shall
be under the sole dominion and control of the Owner Trustee for the benefit of
the Certificateholders.  If, at any time, the Certificate Distribution Account
ceases to be

                                      -10-
<PAGE>

an Eligible Deposit Account, the Servicer shall within 10 Business Days (or such
longer period, not to exceed 30 calendar days, as to which each Rating Agency
may consent) establish a new Certificate Distribution Account as an Eligible
Deposit Account and shall cause the Owner Trustee to transfer any cash and/or
any investments in the old Certificate Distribution Account to such new
Certificate Distribution Account.

          SECTION 5.2   Application of Trust Funds.
                        --------------------------

          (a)  On each Distribution Date, the Owner Trustee shall (based on the
information contained in the Servicer's Certificate delivered on the related
Determination Date) distribute to the Certificateholders, on a pro rata basis,
amounts deposited in the Certificate Distribution Account pursuant to Sections
4.07(b), 5.01(b)(i), 5.03(b), 5.05, 9.02(a) and 9.02(d) of the Pooling and
Servicing Agreement.

          (b)  On each Distribution Date, the Owner Trustee shall send (or shall
cause to be sent) to each Certificateholder the statement described in Section
4.09(a) of the Pooling and Servicing Agreement.

          (c)  If any withholding tax is imposed on distributions of the Owner
Trust Estate (or allocations 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 is hereby authorized and directed to
retain from amounts otherwise distributable to the Certificateholders sufficient
funds for the payment of any tax that is legally required to be paid by the
Owner Trustee, on behalf of 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 Owner Trustee 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 in its sole discretion withhold such
amounts in accordance with this subsection 5.2(c). 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.

          (d)  If the Indenture Trustee holds escheated funds for payment to the
Trust pursuant to Section 3.3(e) of the Indenture, the Owner Trustee shall, upon
notice from the Indenture Trustee that such funds exist, submit an Issuer Order
to the Indenture Trustee pursuant to Section 3.3(e) of the Indenture instructing
the Indenture Trustee to pay such funds to or at the order of the Seller.

          SECTION 5.3   Method of Payment.  Subject to Section 7.1(c),
                        -----------------
distributions required to be made to Certificateholders on any Distribution Date
shall be made to each Certificateholder of record on the related Record Date (i)
by wire transfer, in immediately available funds, to the account of such Holder
at a bank or other entity having appropriate facilities therefor or, where

                                      -11-
<PAGE>

possible, by intra-bank book entry credit, if such Certificateholder shall have
provided to the Certificate Registrar appropriate written instructions at least
five Business Days prior to such Record Date and the distribution required to be
made to such Certificateholders exceeds $100,000 or (ii) by check mailed to such
Certificateholder at the address of such Holder appearing in the Certificate
Register.

          SECTION 5.4   Accounting and Reports to the Certificateholders, the
                        -----------------------------------------------------

cause to be maintained) the books of the Trust on the basis of a fiscal year
ending October 31 on the accrual method of accounting, (b) deliver to each
Certificateholder, as may be required by the Code and applicable Treasury
Regulations or otherwise, such information as may be required to enable each
Certificateholder to prepare its federal income tax returns, (c) file such tax
returns relating to the Trust 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
division or branch of the Seller for federal income tax purposes, (d) cause such
tax returns to be signed in the manner required by law and (e) collect or cause
to be collected any withholding tax as described in and in accordance with
subsection 5.2(c) with respect to income or distributions to Certificateholders.

          SECTION 5.5   Signature on Returns.  The Owner Trustee shall sign on
                        --------------------
behalf of the Trust any and all tax returns of the Trust, unless applicable law
requires a Certificateholder to sign such documents, in which case such
documents shall be signed by the Seller.

hereunder or under any Basic Document, and the Owner Trustee shall not be liable
for the default or failure of the Administrator to carry out its obligations
under the Administration Agreement.

                                      -12-
<PAGE>

          (c)  In the absence of bad faith on its part, the Owner Trustee may
conclusively rely upon certificates or opinions furnished to the Owner Trustee
and conforming to the requirements of this Agreement in determining the truth of
the statements and the correctness of the opinions contained therein; provided,
                                                                      --------
however, that the Owner Trustee  shall have examined such certificates or
-------
opinions so as to determine compliance of the same with the requirements of this
Agreement.

          (d)  The Owner Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful

under such general conditions as may be prescribed by law, and the Owner Trustee
shall not be liable for any interest thereon.

          (f)  The Owner Trustee shall not take any action that (i) is
inconsistent with the purposes of the Trust set forth in Section 2.3 or (ii)
would, to the actual knowledge of a Responsible Officer of the Owner Trustee,
result in the Trust's becoming taxable as a corporation for federal income tax
purposes.

          (g)  The Certificateholders shall not direct the Owner Trustee to take
action that would violate the provisions of this Section 6.1.

          SECTION 6.2   Rights of Owner Trustee.  The Owner Trustee is
                        -----------------------
authorized and directed to execute and deliver the Basic Documents and each
certificate or other document attached as an exhibit to or contemplated by the
Basic Documents to which it is to be a party, on behalf of the Trust, in such
form as the Seller shall approve as evidenced conclusively by the Owner
Trustee's execution thereof.  In addition to the foregoing, the Owner Trustee is
authorized, but shall not be obligated, to take all actions required of it, on
behalf of the Trust, pursuant to the Basic Documents. The Owner Trustee is
further authorized from time to time to take such action as the Administrator

own willful misconduct or (ii) in the case of the inaccuracy of any
representation or warranty contained in Section 6.6 and expressly made by the
Owner Trustee. In particular, but not by way of limitation (and subject to the
exceptions set forth in the preceding sentence):

indebtedness evidenced by or arising under any of the Basic Documents, including

conduct or defend any litigation under this Agreement or otherwise or in
relation to this Agreement or any Basic Document, at the request, order or
direction of any of the Certificateholders, unless such Certificateholders have

          SECTION 6.4   Action upon Instruction by Certificateholders.
                        ---------------------------------------------

          (a)  Subject to Section 4.4 and Section 6.1(g), the Certificateholders

the Certificateholders pursuant to Section 4.5.

          (b)  Notwithstanding the foregoing, the Owner Trustee shall not be
required to take any action hereunder or under any Basic 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 hereof or of any Basic Document or is
otherwise contrary to law.

          (c)  Whenever the Owner Trustee is unable to decide between
alternative courses of action permitted or required by the terms of this
Agreement or any Basic Document, or is unsure as to the application, intent,
interpretation or meaning of any provision of this Agreement or the Basic
Documents, 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 such instruction

within ten 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 which is consistent, in its view, with this Agreement or the
Basic Documents, and as it

                                      -15-

Owner Trustee under the Basic Documents.

          SECTION 6.6 Representations and Warranties of Owner Trustee. The
                      -----------------------------------------------
Owner Trustee hereby represents and warrants to the Seller, for the benefit of
the Certificateholders, that:

          (a)  It is a national bank duly organized, validly existing and in

(i) shall not violate any provision of any law or regulation governing the
banking and trust powers of the Owner Trustee or any order, writ, judgment or
decree of any court, arbitrator or governmental authority applicable to the
Owner Trustee or any of its assets, (ii) shall not violate any provision of the
charter or by-laws of the Owner Trustee, or (iii) shall not violate any
provision of, or constitute, with or without notice or lapse of time, a default
under, or result in the creation or imposition of any lien on any properties
included in the Owner Trust Estate pursuant to the provisions of any mortgage,
indenture, contract, agreement or other undertaking to which it is a party,
which violation, default or lien could reasonably be expected to have a
materially adverse effect on the Owner Trustee's performance or ability to
perform its duties as Owner Trustee under this Agreement or on the transactions
contemplated in this Agreement.

          (d)  The execution, delivery and performance by the Owner Trustee of
this Agreement shall not require the authorization, consent or approval of, the
giving of notice to, the filing or registration with, or the taking of any other
action in respect of, any governmental authority or agency regulating the
corporate trust activities of Chase Manhattan Bank USA, National Association.

          (e)  This Agreement has been duly executed and delivered by the Owner
Trustee and constitutes the legal, valid and binding agreement of the Owner
Trustee, enforceable in accordance with its terms, except as enforceability may
be limited by bankruptcy, insolvency, reorganization, or other similar laws
affecting the enforcement of creditors' rights in general and by general
principles of equity, regardless of whether such enforceability is considered in
a proceeding in equity or at law.

          SECTION 6.7  Reliance; Advice of Counsel.
                       ---------------------------

          (a)  The Owner Trustee shall incur no liability to anyone in acting
upon any signature, instrument, notice, resolution, request, consent, order,
certificate, report, opinion, bond or other document or paper believed by it to
be genuine and believed by it to be signed by the proper party or parties and
need not investigate any fact or matter in any such document. The Owner Trustee
may accept a certified copy of a resolution of the board of directors or other
governing body of any corporate party as conclusive evidence that such
resolution has been duly adopted by such body and that the same is in full force
and effect. As to any fact or matter the method of the determination of which is
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
Owner Trustee for any action taken or omitted to be taken by it in good faith in
reliance thereon.

          (b)  In the exercise or administration of the trusts hereunder and in
the performance of its duties and obligations under this Agreement or the Basic
Documents, the Owner Trustee: (i) may act directly or through its agents,

reasonable care; and (ii may consult with counsel, accountants and other skilled
professionals 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 opinion or advice of any such counsel, accountants
or other such Persons and not contrary to this Agreement or any Basic Document.

          SECTION 6.8  Owner Trustee May Own Certificates and Notes.  The
                       --------------------------------------------
Owner Trustee in its individual or any other capacity may become the owner or

                       --------------------------
receive as compensation from the Seller for its services hereunder such fees as
have been separately agreed upon before the date hereof between the Seller and
the Owner Trustee, and the Owner Trustee shall be entitled to be reimbursed by
the Servicer for its other reasonable expenses hereunder, including the
reasonable compensation, expenses and disbursements of such agents, custodians,
nominees, representatives, experts and counsel as it may employ in connection
with the exercise and performance of its rights and its duties hereunder. The
Servicer shall indemnify the Owner Trustee and its successors, assigns, agents
and servants in accordance with the provisions of Section 7.01 of the Pooling
and Servicing Agreement. The compensation and indemnities described in this
Section 6.9 shall survive the resignation or termination of the Owner Trustee or
the termination of this Agreement. Any amounts paid to the Owner Trustee
pursuant to this Article VI shall not be deemed to be a part of the Owner Trust
Estate immediately after such payment.

          SECTION 6.10 Replacement of Owner Trustee.
                       ----------------------------

                                      -17-
<PAGE>

          (a)    The Owner Trustee may give notice of its intent to resign and
be discharged from the trusts hereby created by written notice thereof to the
Administrator; provided that no such resignation shall become effective, and the
Owner Trustee shall not resign, prior to the time set forth in Section 6.10(c).
The Administrator may appoint a successor Owner Trustee by delivering a written
instrument, in duplicate, to the resigning Owner Trustee and the successor Owner
Trustee. If no successor Owner Trustee shall have been appointed and have
accepted appointment within 30 days after the giving of such notice, the
resigning Owner Trustee giving such notice may petition any court of competent
jurisdiction for the appointment of a successor Owner Trustee. The Administrator
shall remove the Owner Trustee if:

          (i)    the Owner Trustee shall cease to be eligible in accordance with
     the provisions of Section 6.13 and shall fail to resign after written
     request therefor by the Administrator;

          (ii)   the Owner Trustee shall be adjudged bankrupt or insolvent;

          (iii)  a receiver or other public officer shall be appointed or take
     charge or control of the Owner Trustee or of its property or affairs for
     the purpose of rehabilitation, conservation or liquidation; or

          (iv)   the Owner Trustee shall otherwise be incapable of acting.

          (b)    If the Owner Trustee gives notice of its intent to resign or is
removed or if a vacancy exists in the office of Owner Trustee for any reason,
the Administrator shall promptly appoint a successor Owner Trustee by written
instrument, in duplicate (one copy of which instrument shall be delivered to the
outgoing Owner Trustee so removed and one copy to the successor Owner Trustee)
and shall pay all fees owed to the outgoing Owner Trustee.

          (c)    Any resignation or removal of the Owner Trustee and appointment
of a successor Owner Trustee pursuant to any of the provisions of this Section
6.10 shall not become effective and no such resignation shall be deemed to have
occurred until a written acceptance of appointment is delivered by the successor
Owner Trustee to the outgoing Owner Trustee and the Administrator and all fees
and expenses due to the outgoing Owner Trustee are paid. Any successor Owner
Trustee appointed pursuant to this Section 6.10 shall be eligible to act in such
capacity in accordance with Section 6.13 and, following compliance with the
preceding sentence, 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 Administrator shall provide
notice of such resignation or removal of the Owner Trustee to each of the Rating
Agencies.

          (d)    The predecessor Owner Trustee shall upon payment of its fees
and expenses deliver to the successor Owner Trustee all documents and statements
and monies held by it under this Agreement. 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.

                                      -18-
<PAGE>

          (e)  Upon acceptance of appointment by a successor Owner Trustee
pursuant to this Section 6.10, the Administrator shall mail notice of the
successor of such Owner Trustee to all Certificateholders, the Indenture
Trustee, the Noteholders and the Rating Agencies.

          SECTION 6.11 Merger or Consolidation of Owner Trustee.  Any Person
                       ----------------------------------------
into which the Owner Trustee may be merged or converted or with which it may be
consolidated, or any Person resulting from any merger, conversion or
consolidation to which the Owner Trustee shall be a party, or any Person
succeeding to all or substantially all of the corporate trust business of the
Owner Trustee, shall be the successor of the Owner Trustee hereunder, provided
such Person shall be eligible pursuant to Section 6.13, and without the
execution or filing of any instrument or any further act on the part of any of
the parties hereto; provided, however, that the Owner Trustee shall mail notice
                    --------  -------
of such merger or consolidation to the Rating Agencies.

          SECTION 6.12 Appointment of Co-Trustee or Separate Trustee.
                       ---------------------------------------------

          (a)  Notwithstanding any other provisions of this Agreement, 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 shall execute and deliver all instruments to appoint one or more
Persons approved by the Owner Trustee to act as co-trustee, jointly with the
Owner Trustee, or as separate trustee or trustees, of all or any part of the
Owner Trust Estate, and to vest in such Person, in such capacity, such title to
the Owner Trust Estate, or any part thereof, and, subject to the other
provisions of this Section 6.12, such powers, duties, obligations, rights and
trusts as the Administrator and the Owner Trustee may consider necessary or
desirable. If the Administrator shall not have joined in such appointment within
15 days after the receipt by it of a request to do so, 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 pursuant to Section 6.13 and no notice of the appointment of
any co-trustee or separate trustee shall be required pursuant to Section 6.10.

          (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 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 is not 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;

                                      -19-
<PAGE>

          (ii)   no trustee under this Agreement shall be personally liable by
     reason of any act or omission of any other trustee under this Agreement
     (unless such other trustee acts or fails to act at the direction of such
     first trustee); 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. 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 appoint the
Owner Trustee as its agent or attorney-in-fact with full power and authority, to
the extent not prohibited 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 6.13  Eligibility Requirements for Owner Trustee. The Owner
                        ------------------------------------------
Trustee shall at all times: (a) be a corporation, a national banking association
or a bank; (b) be authorized to exercise corporate trust powers; (c) have a
combined capital and surplus of at least $50,000,000 and be subject to

or be otherwise satisfactory to Moody's Investors Service, Inc. If such Person
or bank shall publish reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then
for the purpose of this Section 6.13, the combined capital and surplus of such
Person or bank 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
this Section 6.13, the Owner Trustee shall resign immediately in the manner and
with the effect specified in Section 6.10.

                        TERMINATION OF TRUST AGREEMENT

          SECTION 7.1 Termination of Trust Agreement.
                      ------------------------------

          (a)  This Agreement (other than Section 6.9) and the Trust shall
terminate and be of no further force or effect on the final distribution by the
Owner Trustee of all monies or other property or proceeds of the Owner Trust
Estate in accordance with the terms of the Indenture, the Pooling and Servicing
Agreement (including the exercise by the Servicer of its option to purchase the
Receivables pursuant to Section 9.01 of the Pooling and Servicing Agreement) and
Article V; provided, however, that in no event shall the Trust created by this
Agreement continue beyond the expiration of 21 years from the date hereof. The
bankruptcy, liquidation, dissolution, death or incapacity of any
Certificateholder shall not (x) operate to terminate this Agreement or the
Trust, nor (y) 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 the Owner Trust
Estate nor (z) otherwise affect the rights, obligations and liabilities of the
parties hereto.

          (b)  This Agreement shall be irrevocable. Except as provided in
Section 7.1(a) and in this Section 7.1(b), neither the Seller nor any
Certificateholder shall be entitled to revoke or terminate the Trust or this
Agreement. Each of the Seller and the Owner Trustee acknowledges that the
Indenture Trustee, on behalf of the Noteholders, is a third-party beneficiary of
this Agreement. For so long as the Notes are outstanding, neither the Trust nor
this Agreement shall be revoked without the consent of the Indenture Trustee.
Each of the Seller and the Owner Trustee acknowledges that the Indenture
Trustee, as an agent of the Noteholders, maintains a legitimate interest in
ensuring that the Trust is not revoked prior to the fulfillment of the Trust
objectives. In no event may this Agreement be amended without the consent of the
Indenture Trustee if the effect of such amendment is the revocation or
termination of this Trust other than in accordance with this Section 7.1.

          (c)  Notice of any termination of the Trust specifying the
Distribution Date upon which the Certificateholders shall surrender their
Certificates to the Owner Trustee for payment of the final distribution and
cancellation, shall be given by the Owner Trustee by letter to
Certificateholders mailed within five Business Days of receipt of notice of such
termination from the Servicer given pursuant to subsection 9.02(b) of the
Pooling and Servicing Agreement, stating: (i) the Distribution Date upon or with
respect to which the final distribution on the Certificates shall be made upon
presentation and surrender of the Certificates at the office of the Owner
Trustee; (ii) the amount of any such final distribution; and (iii) that the
Record Date otherwise applicable to such Distribution Date is not applicable,
distributions being made only upon presentation and surrender of the
Certificates at the office of the Owner Trustee therein specified. The Owner
Trustee shall give such notice to the Certificate Registrar (if other than the
Owner Trustee) and the Owner Trustee at the time such notice is given to
Certificateholders. Upon presentation and surrender of the Certificates, the
Owner Trustee shall cause to be distributed to Certificateholders amounts
distributable on such Distribution Date pursuant to Section 5.2.

                                      -21-
<PAGE>

          (d)  If all of the Certificateholders shall not surrender their
Certificates for cancellation within six months after the date specified in the
written notice specified in Section 7.1(c), 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 laws with respect to
escheat of funds, any funds remaining in the Owner Trust Estate after exhaustion
of such remedies in the preceding sentence shall be deemed property of the
Seller and distributed by the Owner Trustee to the Seller.

          (e)  Within sixty days of the later of (i) the cancellation of all of
the Certificates pursuant to Section 7.1(c) or Section 7.1(d), or (ii) payment
to the Seller of funds remaining in the Owner Trust Estate pursuant to Section
7.1(d), the Owner Trustee shall provide each of the Rating Agencies with written
notice stating that all Certificates have been so canceled or such funds have
been so paid to the Seller.

other provision in this Agreement or any other Basic Document, (iii) add or
supplement any credit enhancement for the benefit of the Securityholders

not, as evidenced by an Opinion of Counsel, adversely affect in any material
respect the interests of any class of the Securityholders), (iv) add to the
covenants, restrictions or obligations of the Seller or the Owner Trustee for
the benefit of the Securityholders, (v) evidence and provide for the acceptance

                       -------------------------------------------------
Noteholders. This Agreement may be amended from time to time by the Seller
and the Owner Trustee with the consent of Noteholders whose Notes evidence not

close of business on the preceding Distribution Date and the consent of the
Holders of Certificates evidencing not less than a majority of the ownership
interests in the Owner Trust Estate as of the close of business on the preceding

the Notes or Certificates) 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,
collections of payments on Receivables or distributions that shall be required
to be made on any Note or the Specified Reserve Account Balance, (b) reduce the
aforesaid percentage required to consent to any such amendment or (c) amend
