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

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

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.

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

          (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 protected purchaser (as defined in Article 8 of the Uniform
Commercial Code) 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 protected 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.

the Certificate Registrar may treat the Person in whose name any Certificate
shall be registered in the Certificate Register as the Certificateholder of such

for all other purposes whatsoever, and neither the Owner Trustee nor the
Certificate Registrar shall be bound by any notice to the contrary.

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, 450 West 33rd Street, New York, New York 10001, 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,

                                       -8-

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 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.

Agreement, except to cure any ambiguity or to amend or supplement any provision
in a manner that would not materially adversely affect the interests of the

Bankruptcy. The Owner Trustee shall not have the power to commence a voluntary

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

Documents or would be contrary to Section 2.3, nor shall the Owner Trustee be
obligated to follow any such direction, if given.

         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-B 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.

                                       -10-

<PAGE>

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 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.

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
possible, by intra-bank book entry credit, if such Certificateholder shall have

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.

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

shall not be liable for any interest thereon.

          (f)  The Owner Trustee shall not take any action that (i) is

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

direction of any of the Certificateholders, unless such Certificateholders have
offered to the Owner Trustee security or indemnity satisfactory to it against

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

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

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
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 instructions
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-

financial statements and any other instruments furnished to the 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

          (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.
                       ---------------------------

                                      -16-

          (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,

of them, and the Owner Trustee shall not be liable for the conduct or misconduct
of such agents, attorneys, custodians or nominees if such agents, attorneys,
custodians or nominees shall have been selected by the Owner Trustee with
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 pledgee

                        --------------------------
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.
                        ----------------------------

          (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.

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

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),
the Interest Rate Swaps 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.

supplement any credit enhancement for the benefit of the Securityholders
(provided that if any such addition shall affect any class of Securityholders
 --------
differently than any other class of Securityholders, then such addition shall
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

of (i) the Holders of the Notes evidencing not less than a majority of the
Outstanding Amount of the Voting Notes, and (ii) Certificateholders whose

Certificate Registrar duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing and (ii) certain opinions required by
Section 3.4(b) of the Trust Agreement, and thereupon one or more new
