such Purchaser from the first day through the last day of that Fixed Period
factoring in actual returns earned during the Fixed Period and assuming
redeployment of such funds in highly rated short-term money market instruments
from the date of principal distribution through the end of the Fixed Period,
then, upon written notice (including a detailed calculation of such Breakage
Payment) from the Administrative Agent to the Servicer, such Purchaser shall be
entitled to receive additional amounts in the amount of such excess (each, a

     SECTION 6.02  Authority, etc.  The Conduit Purchaser has all requisite
                   ---------------
power and authority to enter into and perform its obligations under this
Certificate Purchase Agreement and to consummate the transactions contemplated
hereby and thereby.  The execution and delivery by the Conduit Purchaser of this
Certificate Purchase Agreement and the consummation by the Conduit Purchaser of
the transactions contemplated hereby have been duly and validly authorized by
all necessary corporate action on the part of the Conduit Purchaser.  This
Certificate Purchase Agreement has been duly and validly executed and delivered
by the Conduit Purchaser and constitutes a legal, valid and binding obligation
of the Conduit Purchaser, enforceable against the Conduit Purchaser in
accordance with its terms, subject as to enforcement to bankruptcy,
reorganization, insolvency, moratorium and other similar laws of general
applicability relating to or affecting creditors' rights and to general
principles of equity.  Neither the execution and delivery by the Conduit
Purchaser of this Certificate Purchase Agreement nor the consummation by the
Conduit Purchaser of any of the transactions contemplated hereby, nor

                                       21
<PAGE>

the fulfillment by the Conduit Purchaser of the terms hereof, will conflict

                    --------------
by the Administrative Agent on behalf of the Purchasers pursuant to this
Certificate Purchase Agreement will be acquired for investment only and not with
a view to any public distribution thereof, and no Conduit Purchaser will offer
to sell or otherwise dispose of its interest in the Series 2000-VFC Certificates
so acquired by it (or any interest therein) in violation of any of the
registration requirements of the Act or any applicable state or other securities
laws.  The Administrative Agent and each Purchaser acknowledges that it has no
right to require the Seller to register under the Act or any other securities
law any Series 2000-VFC Certificate to be acquired by the Administrative Agent
on behalf of such Purchaser pursuant to this Certificate Purchase Agreement.

  The Conduit Purchaser, the Committed Purchaser and Administrative Agent have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of an investment in the Series 2000-VFC
Certificates and the Conduit Purchaser and Committed Purchaser are able to bear
the economic risk of such investment. The Conduit Purchaser, Committed Purchaser
and Administrative Agent have reviewed the Pooling and Servicing Agreement and
the Series Supplement (including the schedule and exhibits thereto) and have had
the opportunity to perform due diligence with respect thereto and to ask
questions of and receive answers from the Seller and its representatives
concerning the Seller, the Master Trust and the Series 2000-VFC Certificates.
Each of the Conduit Purchaser, the Committed Purchaser and Administrative Agent
is an "accredited investor" as defined in Rule 501, promulgated by the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended.


     SECTION 6.04   Investment Company Act.  Neither the Conduit Purchaser nor
                    ----------------------
the Administrative Agent is required to register as an "investment company" nor
is the Conduit Purchaser or the Administrative Agent controlled by an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

     SECTION 9.01   Indemnification.  (a) The Seller hereby agrees to indemnify

fees) (collectively, "Seller Losses"), as incurred (payable promptly upon

as incurred (payable promptly upon written request), for or on account of or
arising from or in connection with any breach of any representation, warranty or
covenant of NFC in this Certificate Purchase Agreement or in any certificate or
other written material delivered pursuant hereto.

     (c)  Notwithstanding Sections 9.01(a) and (b), in no event shall any
Indemnified Party be indemnified for Seller Losses or NFC Losses to the extent
(i) resulting from the performance of the Dealer Notes, market fluctuations or
other similar market or investment risks associated with ownership of the Series
2000-VFC Certificates, (ii) which would otherwise be covered in Sections 9.04
and 9.05 hereof, (iii) arising from such Person's gross negligence or willful
misconduct, (iv) arising from a breach of any representation or warranty set
forth in the Pooling and Servicing Agreement, a remedy for the breach of which
is provided in Section 2.06 of the Pooling and Servicing Agreement or (v)
arising from a breach of any representation or warranty set forth in the
Purchase Agreement, a remedy for the breach of which is provided in Section
4.06(d) of the Purchase Agreement.

     SECTION 9.02   Procedure.  In order for an Indemnified Party to be entitled
                    ---------
to any indemnification provided for under this Certificate Purchase Agreement in
respect of, arising out of, or involving a claim made by any Person against the
Indemnified Party (a "Third Party Claim"), such Indemnified Party must notify
                      -----------------
NFC or the Seller, as applicable (the "Applicable Indemnifying Party") in
                                       -----------------------------
writing of the Third Party Claim within a reasonable time after receipt by such
Indemnified Party of written notice of the Third Party Claim unless the
"Applicable Indemnifying Party shall have previously obtained actual knowledge
 -----------------------------
thereof. Thereafter, the Indemnified Party shall deliver to the Applicable
Indemnifying Party, within a reasonable time after the Indemnified Party's
receipt thereof, copies of all notices and documents (including court papers)
received by the Indemnified Party relating to the Third Party Claim.

     SECTION 9.03   Defense of Claims. If a Third Party Claim is made against an
                    -----------------
Indemnified Party, (a) the Applicable Indemnifying Party will be entitled to
participate in the

                                       26
<PAGE>

defense thereof and, (b) if it so chooses, to assume the defense thereof with
counsel selected by the Applicable Indemnifying Party, provided that in
connection with such assumption (i) such counsel is not reasonably objected to
by the Indemnified Party and (ii) the Applicable Indemnifying Party first admits
in writing their joint and several liability to indemnify the Indemnified Party
with respect to all elements of such claim in full.  Should the Applicable
Indemnifying Party so elect to assume the defense of a Third Party Claim, the
Applicable Indemnifying Party will not be liable to the Indemnified Party for
any legal expenses subsequently incurred by the Indemnified Party in connection
with the defense thereof.  If the Applicable Indemnifying Party elects to assume
the defense of a Third Party Claim, the Indemnified Party will (i) cooperate in
all reasonable respects with the Applicable Indemnifying Party in connection
with such defense and (ii) not admit any liability with respect to, or settle,
compromise or discharge, such Third Party Claim without the Applicable
Indemnifying Party's prior written consent, as the case may be.  If the
Applicable Indemnifying Party shall assume the defense of any Third Party Claim,
the Indemnified Party shall be entitled to participate in (but not control) such
defense with its own counsel at its own expense.  If the Applicable Indemnifying
Party does not assume the defense of any such Third Party Claim, the Indemnified
Party may defend the same in such manner as it may deem appropriate, including
settling such claim or litigation after giving notice to the Applicable
Indemnifying Party of such terms and the Applicable Indemnifying Party will
promptly reimburse the Indemnified Party upon written request.  Anything
contained in this Certificate Purchase Agreement to the contrary
notwithstanding, neither the Applicable Indemnifying Party shall be entitled to
assume the defense of any part of a Third Party Claim that seeks an order,
injunction or other equitable relief or relief for other than money damages
against the Indemnified Party.

     SECTION 9.04  Indemnity for Taxes, Reserves and Expenses. (a) If after the
                   ------------------------------------------
date hereof, the adoption of any Governmental Rule or bank regulatory guideline
or any amendment or change in the interpretation of any existing or future
Governmental Rule or bank regulatory guideline by any Governmental Authority
charged with the administration, interpretation or application thereof, or the
compliance with any directive of any Governmental Authority (in the case of any
bank regulatory guideline, whether or not having the force of Governmental
Rule):

     (i)  shall subject any Indemnified Party to any tax, duty, deduction or
other charge with respect to the Dealer Notes, the Pooling and Servicing
Agreement, the Series Supplement, the Series 2000-VFC Certificates, this
Certificate Purchase Agreement or payments of amounts due thereunder, or shall
change the basis of taxation of payments to any Indemnified Party of amounts
payable in respect thereof (except for changes in the rate of general corporate,
franchise, net income or other income tax (including by means of withholding)
imposed on such Indemnified Party by the United States of America, the
jurisdiction in which such Indemnified Party's principal executive office is
located or any other jurisdiction in which the Indemnified Party would be
subject to such tax even if the transactions contemplated by this Agreement had
not occurred); or

                                       27
<PAGE>

     (ii)   shall impose, modify or deem applicable any reserve, capital,
special deposit or similar requirement (including, without limitation, any such
requirement imposed by the Board of Governors of the Federal Reserve System)
against assets of, deposits with or for the account of, or credit extended by,
any Indemnified Party or shall impose on any Indemnified Party or on the United
States market for certificates of deposit or the London interbank market any
other condition affecting the Dealer Notes, the Pooling and Servicing Agreement,
the Series Supplement, the Series 2000-VFC Certificates, this Certificate
Purchase Agreement or payments of amounts due thereunder (including with respect
to Eurocurrency liability reserves); or

     (iii)  imposes upon any Indemnified Party any other cost or expense
(including, without limitation, reasonable attorneys' fees and expenses, and
expenses of litigation or preparation therefor in contesting any of the
foregoing if such a contest is requested by the Applicable Indemnifying Party)
with respect to the Dealer Notes, the Series 2000-VFC Certificates, any Series
Document or payments of amounts due hereunder or thereunder; and the result of
any of the foregoing is to increase the cost or reduce the payments to such
Indemnified Party with respect to the Dealer Notes, the Pooling and Servicing
Agreement, the Series Supplement, the Series 2000-VFC Certificates, this
Certificate Purchase Agreement or payments of amounts due thereunder or the
obligations thereunder or the funding of any purchases (including Incremental
Fundings) with respect thereto by any Purchaser, by an amount deemed by such
Indemnified Party to be material, then such amount or amounts as will compensate
such Indemnified Party for such increased cost or reduced payments shall be
payable to such Indemnified Party in accordance with Section 9.05(c).
                                                     ---------------

     (b)    If any Indemnified Party shall have determined that, after the date
hereof, the adoption of any applicable Law or bank regulatory guideline
regarding capital adequacy, or any change therein, or any change in the
interpretation thereof by any Governmental Authority, or any directive regarding
capital adequacy (in the case of any bank regulatory guideline, whether or not
having the force of law) of any such Governmental Authority, has or would have
the effect of reducing the rate of return on capital of such Indemnified Party
(or its parent) as a consequence of such Indemnified Party's obligations
hereunder or with respect hereto to a level below that which such Indemnified
Party (or its parent) could have achieved but for such adoption, change, request
or directive (taking into consideration its policies with respect to capital
adequacy) by an amount deemed by such Indemnified Party to be material, then
from time to time, such additional amount or amounts as will compensate such
Indemnified Party (or its parent) for such reduction shall be payable to such
Indemnified Party in accordance with Section 9.05(c).
                                     ---------------

     (c)    Any Indemnified Party who makes a demand for payment of increased
costs or capital pursuant to Section 9.04(a) or (b) shall promptly deliver to
the Seller a certificate setting forth in reasonable detail the computation of
such increased costs or capital and specifying the basis therefor.  In the
absence of manifest error, such certificate shall be conclusive and binding for
all purposes.  Each Indemnified Party shall use reasonable efforts to mitigate
the effect upon of any such increased costs or capital requirements; provided,
                                                                     --------
it shall not

                                       28

be obligated to take any action that it determines would be disadvantageous to

connection with the execution, delivery, filing and recording of this
Certificate Purchase Agreement, the Series 2000-VFC Certificates or the other
documents and agreements to be delivered hereunder, and agrees to hold each
Purchaser and its Administrative Agent harmless from and against any liabilities
with respect to or resulting from any delay in paying or omission to pay such

required to make such payments within 10 days after demand therefor by the
Administrative Agent or the applicable payee.

institution under its commercial paper program as a result of any events or
circumstances similar to those described in Sections 9.04 or 9.05(c), the
Conduit Purchaser shall promptly deliver to the Seller a certificate setting
forth in reasonable detail the computation of such amounts.  In the absence of
manifest error, such certificate shall be conclusive and binding for all
purposes.  The Seller shall be obligated to pay to the Conduit Purchaser,
promptly after receipt of such certificate, such additional amounts as may be
necessary to reimburse the Conduit Purchaser for any amounts so paid by the

appointment of and authorizes the Administrative Agent to take such action as
agent on its behalf and to exercise such powers as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto. The Administrative Agent reserves the right, in
its sole discretion, to take any actions and exercise any rights or remedies
under this Certificate Purchase Agreement and any related agreements and
documents.  Except for actions which the Administrative Agent is expressly
required to take pursuant to this Certificate Purchase Agreement or the Asset

action which exposes the Administrative Agent to personal liability or which is
contrary to applicable law unless the Administrative Agent shall receive further
assurances to its satisfaction from the Purchasers, of the indemnification
obligations under Section 10.04 hereof against any and all liability and expense
which may be incurred in taking or continuing to take such action.  The
Administrative Agent agrees to give to the Purchasers prompt notice of each

Pooling and Servicing Agreement or the Series Supplement.  Subject to Section

then the retiring Administrative Agent may, on behalf of the Purchasers, appoint
a successor Administrative Agent.  If such successor Administrative Agent is not
an Affiliate of the resigning Administrative Agent, such successor
Administrative Agent shall be subject to the Seller's prior written approval
(which approval will not be unreasonably withheld or delayed).  Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all of the rights, powers, privileges and
duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations under this Certificate
Purchase Agreement.  After any retiring Administrative Agent's resignation
hereunder as Administrative Agent, the provisions of this Article X shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was
an Administrative Agent under this Certificate Purchase Agreement.

accordance with applicable law, at any time sell to one or more Persons (each, a

 -----------
obligations under this Certificate Purchase Agreement.  Notwithstanding any such
sale by a Purchaser of participating interests to a Participant, such
Purchaser's rights and obligations under this Certificate Purchase Agreement
shall remain unchanged, such Purchaser shall remain solely responsible for the
performance thereof, and the Seller and the Administrative Agent shall continue
to deal solely and directly with such Purchaser in connection with such
Purchaser's rights and obligations under this Certificate Purchase Agreement.
The Seller also agrees that each Participant shall be entitled to the benefits
of Article IX hereof; provided, however, that all amounts payable by the Seller
                      --------  -------
to any such Participant shall be limited to the amounts which would have been
payable to the Purchaser selling such participating interest had such interest
not been sold.

     (d)  This Certificate Purchase Agreement shall create and constitute the
continuing obligation of the parties hereto in accordance with its terms, and

with respect to the Series 2000-VFC Certificates shall have been paid in full.

                       TO POOLING AND SERVICING AGREEMENT
                       ----------------------------------

          SERIES 2000-VFC SUPPLEMENT dated as of January 28, 2000 (the "Series
Supplement"), by and among NAVISTAR FINANCIAL SECURITIES CORPORATION, a Delaware
corporation, as Seller (the "Seller"), NAVISTAR FINANCIAL CORPORATION, a
Delaware corporation, as Servicer (the "Servicer"), and THE BANK OF NEW YORK, a
New York banking corporation, as trustee (together with its successors in trust
thereunder as provided in the Agreement referred to below, the "Master Trust
Trustee") under the Pooling and Servicing Agreement, dated as of June 8, 1995
(as amended and supplemented, the "Agreement") among the Seller, the Servicer,
the Master Trust Trustee and The Chase Manhattan Bank (formerly know as Chemical
Bank), as trustee under the 1990 Trust Agreement.

          Section 6.09 of the Agreement provides that the Seller may from time
to time direct the Master Trust Trustee to issue, on behalf of the Master Trust,
one or more new Series of Investor Certificates representing fractional
undivided interests in the Master Trust.  The Principal Terms of any new Series
are to be set forth in a Supplement to the Agreement.

          Pursuant to this Series Supplement, the Seller and the Master Trust
Trustee shall create a new Series of Investor Certificates and specify the
Principal Terms thereof.

                        THE SERIES 2000-VFC CERTIFICATES

     SECTION   1.01 Designation.
                    -----------

          (a)  There is hereby created a new Series pursuant to the Agreement
and this Series Supplement to be known as the "Floating Rate Dealer Note Asset
Backed Certificates Series 2000-VFC." The interest of the Investor
Certificateholders in Series 2000-VFC shall be represented by the Series 2000-
VFC Certificates. The Series 2000-VFC Certificates are a series of variable
funding certificates, meaning that their Funded Amount may be increased from
time to time during the Revolving Period as Incremental Fundings are made under
the Certificate Purchase Agreement and may be decreased from time to time, as
Investor Principal Collections or certain other funds are distributed to the
Series 2000-VFC Certificateholders for that purpose. The Funded Amount of the
Series 2000-VFC may not at any time exceed the Maximum Funded Amount.
<PAGE>

          (b)  If any term or provision contained herein shall conflict with or
be inconsistent with any term or provision contained in the Agreement, the terms
and provisions of this Series Supplement shall govern with respect to Series
2000-VFC.

     SECTION   1.02 Incremental Fundings.  Incremental Fundings may occur on any
                    --------------------
Distribution Date to the extent provided in the Certificate Purchase Agreement.
Upon any Incremental Funding, the Funded Amount, the Series Allocation
Percentage, the Floating Allocation Percentage and other terms will be reset to
the extent provided herein and in the Certificate Purchase Agreement.

     SECTION   1.03 Optional Early Pay Out.
                    ----------------------

          (a)  On any Funding Change Date falling in the Revolving Period, the
Seller may cause the principal portion of the Certificates to be prepaid in full
or in part, (x) if the aggregate principal amount of such prepayment is greater
than $150,000,000, on not less than five Business days prior written notice by
the Servicer or (y) otherwise, on not less than three Business Days prior
written notice by the Servicer to the Master Trust Trustee and the
Administrative Agent, with Shared Principal Collections as provided in Section
4.03(e) of the Agreement; provided, however that such prepayment shall not be
permitted unless all due (or if the Certificates are paid in full, all accrued)
and unpaid Monthly Interest, Additional Amounts and Non-Use Fees have been paid
in full.

          (b)  In addition, on any Business Day, the Seller may cause the
principal portion of the Certificates to be prepaid in full or in part, (x) if
the aggregate principal amount of such prepayment is greater than $150,000,000,
on not less than five Business Days prior written notice by the Servicer or (y)
otherwise, on not less than three Business Days prior written notice by the
Servicer to the Master Trust Trustee and the Administrative Agent, with the
proceeds from issuance of a new Series issued substantially contemporaneously
with such prepayment; provided, however that such prepayment shall not be
permitted unless all due (or, if the Certificates are paid in full, all accrued)
and unpaid Monthly Interest, Additional Amounts and Non-Use Fees have been paid
in full.

          (c)  Servicer shall not give notice of any prepayment pursuant to
Section 1.03(a) unless the Master Trust has funds sufficient to make such
prepayment on the day notice is given and shall not give notice of any
prepayment pursuant to Section 1.03(b) unless the Seller has obtained binding
commitments which may be subject to customary conditions from one or more
persons to purchase the new series in such amounts as will yield the net
proceeds necessary to make the prepayment.

                                 SERVICING FEE

"Monthly Servicing Fee") shall be payable to the Servicer, in arrears, on each
Distribution Date in respect of a Due Period (or portion thereof) occurring

extent amounts are available therefor pursuant to Section 4.04(a)(vi); and

so paid, the related portion of the Monthly Servicing Fee to be paid by the

          (a)  On each Transfer Date, the Servicer shall determine the amount
(the "Deficiency Amount"), if any, by which the amount of the entire allocations
required on such Transfer Date by Sections 4.04(a)(i) through (iv) exceeds the

and Excess Interest Collections allocated to Series 2000-VFC on such Transfer
Date, if any, for the related Due Period.

          (b)  If the Deficiency Amount for any Transfer Date is greater than
zero, the Master Trust Trustee, acting in accordance with instructions from the

following order of priority in the same manner as Available Certificateholder
Interest Collections, each of which applications shall reduce such Deficiency
Amount (all such available funds being the "Available Draw Funds" for such
Transfer Date):

               (ii)  funds on deposit in the Spread Account;

Section 4.05(b).

          (c)  If all of the amounts applied pursuant to Section 4.05(a) and (b)
are insufficient to make the entire application described in Section
4.04(a)(iii), the Available Subordinated Amount shall be reduced (but not below
zero) by the amount of such deficiency and any remaining Investor Dealer Note
Losses shall be deemed to be reimbursed to the extent of such reduction.

     SECTION 4.06  Investor Charge-Offs.  If, for any Transfer Date on which the
                   --------------------
Available Subordinated Amount equals or is reduced to zero (after giving effect
to the allocations, distributions, withdrawals and deposits to be made on such
Transfer Date) and the Deficiency Amount for such Transfer Date (as reduced by
the applications required by Section 4.05 of this Series Supplement) is greater
than zero, the Invested Amount shall be reduced by the lesser of (i) such
remaining Deficiency Amount for such Transfer Date and (ii) the amount of
Investor Dealer Note Losses for the related Due Period remaining unreimbursed
after all applications of funds or reductions of the Available Subordinated
Amount pursuant to Section 4.04 and 4.05 (such lesser amount being an "Investor
Charge-Off").

such shortfall.

               (iv)  "Series 2000-VFC Shared Seller Principal Collections" means

Reserve Account then funds shall be withdrawn in an amount equal to the Early

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

same manner as Investor Principal Collections pursuant to Section 4.08(b) and
otherwise will be deposited in the Excess Funding Account to the extent
necessary to maintain the Master Trust Seller's Interest at an amount equal to
(or, in the discretion of the Seller, greater than) the Minimum Master Trust

transfer to the Distribution Account the funds on deposit in the Series
Principal Account and shall make, without duplication, the following
distributions from the Distribution Account:

               ----------------------
Expected Payment Date), Monthly Interest, Non-Use Fees and Additional Amounts
will be distributed as such to the Series 2000-VFC Certificateholders to the
extent of the amount on deposit in the Distribution Account for such purpose.

          (c)  Revolving Period.  On each Distribution Date relating to a Due
               ----------------

     SECTION 4.11  [Reserved]

     SECTION 4.12  Partial Month Due Period.  The allocation and distribution
                   ------------------------
provisions in this Series Supplement are based upon the assumptions that each
Due Period will be a calendar month and that each Due Period will have a unique
related Transfer Date and Distribution Date. However, under certain
circumstances (such as the occurrence of an Early Amortization Event, the
Revolving Period could end on a date other than the last day of a calendar month
(the period from the first day of such month (the "Subject Month") to and
including the date of such occurrence being referred to herein as the "Revolving
Due Period"), and an Early Amortization

                                       26
<PAGE>

Period could commence on a date other than the first day of a calendar month
(the period from such other date until the last day of the Subject Month being
the "Amortizing Due Period"). If such a circumstance occurs, then the Servicer,
the Seller and the Master Trust Trustee shall observe the following rules:

               (i)   the Transfer Date for both the Revolving Due Period and the
     Amortizing Due Period shall be the date on which the Transfer Date would
     have occurred if the Subject Month had been an ordinary Due Period;

               (ii)  the allocations and distributions of Finance Charge
     Collections (and all items derived from Finance Charge Collections, such as
     Available Certificateholder Interest Collections and Available Seller's
     Finance Charge Collections) and Dealer Note Losses occurring during the
     Subject Month shall be made as if the Subject Month were one Due Period,
     without any distinction between the Revolving Due Period and the Amortizing
     Due Period; and

               (iii) two separate sets of allocations and distributions of
     Principal Collections (and all items derived from Principal Collections,
     such as Investor Principal Collections and Seller's Principal Collections)
     shall be made on such Transfer Date, according to whether such Principal
     Collections were received during the Revolving Due Period (in which case
     allocations and distributions shall be made as provided in Sections 4.08(a)
     and (c)) or the Amortizing Due Period (in which case allocations and
     distributions shall be made as provided in Sections 4.08(b) and (d)).

     SECTION 4.13  Additional Rights upon the Occurrence of Certain Events.
                   -------------------------------------------------------
Notwithstanding the provisions of Section 9.02(a) of the Agreement, if any
insolvency event occurs with respect to the Seller, Navistar International
Corporation, Navistar International Transportation Corp. or Navistar Financial
Corporation on the day of such insolvency event, the Seller will (subject to the
actions of the Certificateholders) immediately cease to transfer Dealer Notes to
the Master Trust, and promptly give notice to the Master Trust Trustee of such
insolvency event. Under the terms of the Pooling and Servicing Agreement, if an
insolvency event occurs with respect to the Seller prior to the date on which
the Series 2000-VFC Certificates issued by the Master Trust have been paid in
full, then within 15 days the Master Trust Trustee will publish a notice of such
insolvency event stating that the Master Trust Trustee intends to sell,
liquidate or otherwise dispose of the Dealer Notes in a commercially reasonable
manner and on commercially reasonable terms, unless within a specified period of
time Certificate holders representing more than 50% of the aggregate series
invested amount of the certificates of each such Series and each person holding
a Supplemental Certificate, instruct the Master Trust Trustee not to sell,
dispose of or otherwise liquidate the Dealer Notes and to continue transferring
Dealer Notes as before such insolvency event.
