               (a)       The Servicer, for the benefit of the Agent and the
Purchasers, shall establish and maintain in the name of the Agent, an account
titled "Royal Bank of Canada, as Agent- Navistar Financial 2000-C Collection
Account" (the "Collection Account") and an account titled "Royal Bank of Canada,

Investments shall be retained in the Reserve Account, to the extent the amount
on deposit is less than the Specified Reserve Account Balance. Any Investment
Earnings on funds in the Reserve Account not required to be retained in the

such payment, such Collections shall be held in trust by the Seller for the
exclusive benefit of the Purchasers and the Agent.

     respect to the related Settlement Period, and the Principal Distributable
     Amount for the related Settlement Date, exceeds (II) the Available Amount
     for such Settlement Date; and

                         (iii)   the Servicer shall deposit, out of its own
     funds, the Net Swap Adjustment Amount into the Collection Account and
     Reserve Account as follows: (A) into the Collection Account, the excess, if
     any, of the amount specified in clause (B) of Section 2.1(b)(ii) over the

     amount specified in clause (A) of Section 2.1(b)(ii) and (B) the remainder,
                                       ------------------
     if any, into the Reserve Account.

               (c)       On each Settlement Date, the Agent at the request of
the Servicer shall apply amounts on deposit in the Collection Account, to the
extent of the Total Available Amount, as follows:

                         (i)     first, if the Servicer is not the Seller or an

     Settlement Period and (B) the Facility Fee for such Settlement Period,

                         (iv)    fourth, if the Servicer is the Seller or an
                                 ------
     Affiliate of the Seller, to pay the Total Servicing Fee to the Servicer
     with respect to the related Monthly Period,

                         (v)     fifth, to pay to the Agent for distribution to

     such Settlement Date to be applied to reduce the Capital of the Purchaser
     Interest,

                         (vi)    sixth, to pay to the Reserve Account, an amount
                                 -----

     the amount of funds then on deposit in the Reserve Account,

     continuing, the remaining balance, if any, to the Seller, unless there is a
     Servicer Default, at which time the remaining balance shall be used to
     reduce the Capital and any other Aggregate Unpaids.

               (d)       All payments by or on behalf of an Obligor with respect
to a Receivable (excluding Supplemental Servicing Fees) shall be applied (i)
first, to reduce Outstanding Monthly Advances, if any, with respect to such
-----
Receivable, as described in Section 6.7, (ii) second, to the Scheduled Payment
                            -----------       ------

Scheduled Payment and will thereafter, to the extent the Rebate exceeds the
final Scheduled Payment, reduce Scheduled Payments in reverse chronological

the Securities Intermediary of the amount of, and the Securities Intermediary
shall make, the withdrawals from the Reserve Account required pursuant to
Sections 1.4(b) and 2.1(b)(ii). On each Settlement Date, to the extent that the
------------------------------

long as no Servicer Default shall have occurred and be continuing, the Servicer
may notify (with a copy to the Agent) the Securities Intermediary of the amount
of, and the Securities Intermediary shall withdraw the amount of, such excess
from the Reserve Account and distribute the same to the Seller. Upon the
occurrence of a Servicer Default, the Servicer shall notify (with a copy to the
Agent) the Securities Intermediary of the amount of, and the Securities
Intermediary shall withdraw, all amounts on deposit in the Reserve Account for
application in accordance with Section 2.1(c). To the extent that any funds
                               --------------
remain in the Reserve Account after the Aggregate Unpaids have been indefeasibly
reduced to zero, such funds shall be withdrawn and distributed to, or as
directed by, the Seller. Each Monthly Report shall specify the amount, if any,
which is scheduled to be withdrawn from the Reserve Account and distributed to
the Seller on the next succeeding Settlement Date.

               (b)       If the Servicer, pursuant to Section 6.7, determines on
                                                      -----------
any Settlement Date that it is required to make a Monthly Advance and does not
do so from its own funds, the Servicer shall notify (with a copy to the Agent)
the Securities Intermediary of the amount of such shortfall, and the Securities
Intermediary shall withdraw, funds from the Reserve Account up to the amount of
such shortfall and deposit them in the pursuant to Section 2.1 for
                                                   -----------

purposes of making distributions pursuant to this Agreement, but shall not
otherwise satisfy the Servicer's obligation to deliver the amount of the Monthly
Advances to the Collection Account, and the Servicer shall within two Business
Days replace any funds in the Reserve Account so used. The Servicer shall not be
entitled to reimbursement for any such deemed Monthly Advances unless and until
the Servicer shall have replaced such funds in the Reserve Account.

          Section 2.3    Payment Rescission. No payment of any of the Aggregate
                         ------------------
Unpaids shall be considered paid or applied hereunder to the extent that, at any
time, all or any portion of such payment or application is rescinded by
application of law or judicial authority, or must otherwise be returned or
refunded for any reason. Seller shall remain obligated for the amount of any
payment or application so rescinded, returned or refunded, and shall promptly
pay to the Agent (for application to the Person or Persons who suffered such
rescission, return or refund) the full amount thereof, plus the Default Fee from
the date of any such rescission, return or refunding.

          Section 2.4    Clean Up Call. As of the last day of any Monthly Period
                         -------------
as of which the Capital is 10% or less of the Initial Aggregate Receivables
Balance, the Servicer shall have the option to purchase all (but not less than
all) of the Purchaser Interest (the "Clean-up Call"); provided, however, that
                                     -------------
the Servicer may not exercise the Clean-up Call if the Optional Purchase
Proceeds are insufficient to repay all Aggregate Unpaids. To exercise such
option, the Servicer shall provide the Agent with not less than 10 Business
Days' prior written notice of its intention to do so (the "Clean-up Call
                                                           -------------
Notice"). On or before the day preceding the related Settlement Date, the
------
Servicer shall deposit in the Collection Account an amount equal to the
aggregate Administrative Purchase Payments for the Receivables (including
Liquidating Receivables), included in the Purchaser Interest (less the
Liquidation Expenses to be incurred in connection with the recovery thereof).
The foregoing amounts (the "Optional Purchase Proceeds") shall be paid by the

Servicer into the Collection Account for distribution to the Agent and the
Purchasers in accordance with Section 2.1.

Report with respect to the immediately preceding Monthly Period, executed by any
Authorized Officer of the Servicer, containing all information necessary for
making the calculations, withdrawals, deposits, transfers and distributions
required by this Article II.

          Section 2.6    Deposits Net of Total Servicing Fee. Any provision
                         -----------------------------------
herein to the contrary notwithstanding, for so long as (i) NFC is the Servicer
hereunder and (ii) no Servicer Default has occurred and is continuing, the
deposits into the Collection Account pursuant to Section 2.1(a) may be made net
                                                 --------------
of the Total Servicing Fee to be distributed to the Servicer pursuant to
Sections 2.1(c)(iv) (so long as Collected Interest not yet distributed is
-------------------
sufficient therefor). Nonetheless, the Servicer shall account for the Total
Servicing Fee in the Monthly Report as if such amount had been deposited into
the Collection Account and/or transferred separately.

Eligible Investments shall be made in the name of the Securities Intermediary,
and such investments shall not be sold or disposed of prior to their maturity.
The Servicer shall from time to time appoint a person, which shall initially be
The Chase Manhattan Bank, to act as "Securities Intermediary" , who shall
                                     -----------------------
qualify as a "securities intermediary" within the meaning of Section 8-102 of
the UCC in effect in the State of New York. The Servicer shall provide notice of
such appointment to the Agent and shall use reasonable efforts to obtain the
express agreement of such Person to the obligations of the Securities
Intermediary set forth in Sections 1.4, 2.1, 2.2, 2.7 and 6.12, a copy of which
                          ------------------------------------
agreement shall be delivered to the Agent.

               (a)       With respect to the Designated Account Property, the
Securities Intermediary agrees, by its acceptance hereof, that:

                         (i)    The Designated Accounts are accounts to which
     Financial Assets will be credited and are "securities accounts" within the
     meaning of Section 8-501 of the UCC.

                         (ii)   All securities or other property underlying any
     Financial Assets credited to the Designated Accounts shall be registered in
     the name of the Securities Intermediary, indorsed to the Securities
     Intermediary or in blank or credited to another securities account
     maintained in the name of the Securities Intermediary and in no case will
     any Financial Asset credited to any of the Designated Accounts be
     registered in the name of the Agent, the Company, the Servicer or the
     Seller, payable to the order of the Agent, the Company, the Servicer or the
     Seller or specially indorsed to the Agent, the Company, the Servicer or the
     Seller except to the extent the foregoing have been specially indorsed to
     the Securities Intermediary or in blank.

                         (iii)  All property delivered to the Securities
     Intermediary pursuant to this Agreement will be promptly credited to the
     appropriate Designated Account as directed by the Servicer or as otherwise
     provided herein.

                         (iv)   Each item of property (whether investment
     property, Financial Asset, security, instrument or cash) credited to a
     Designated Account shall be treated as a "financial asset" within the
     meaning of Section 8-102(a)(9) of the New York UCC.

                         (v)    If at any time the Securities Intermediary shall
     receive any order from the Agent directing transfer or redemption of any
     Financial Asset relating to the Securities Accounts, the Securities
     Intermediary shall comply with such entitlement order without further
     consent by the Financial Institutions, the Company, the Servicer, the
     Seller or any other Person.

<PAGE>

                         (vi)    The Designated Accounts shall be governed by
     the laws of the State of New York, regardless of any provision in any other
     agreement. For purposes of the UCC, New York shall be deemed to be the
     Securities Intermediary's jurisdiction and the Designated Accounts (as well
     as the Securities Entitlements related thereto) shall be governed by the
     laws of the State of New York.

                         (vii)   The Securities Intermediary has not entered
     into, and until the termination of this Agreement will not enter into, any
     agreement with any other Person relating to the Designated Accounts and/or
     any Financial Assets credited thereto pursuant to which it has agreed to
     comply with entitlement orders (as defined in Section 8-102(a)(8) of the
     New York UCC) of such other Person and the Securities Intermediary has not
     entered into, and until the termination of this Agreement will not enter
     into, any agreement with the Financial Institutions, any Company, the
     Seller, the Servicer or the Agent purporting to limit or condition the
     obligation of the Securities Intermediary to comply with entitlement orders
     as set forth in Section 2.7(a)(v) above.

                         (viii)  Except for the claims and interest of the
     Agent, and the Company in the Designated Accounts, the Securities
     Intermediary knows of no claim to, or interest in, the Designated Accounts
     or in any Financial Asset credited thereto. If any other person asserts any
     lien, encumbrance or adverse claim (including any writ, garnishment,
     judgment, warrant of attachment, execution or similar process) against the
     Designated Accounts or in any Financial Asset carried therein, the
     Securities Intermediary will promptly notify the Agent, the Company, and
     the Servicer thereof.

                         (ix)    The Securities Intermediary will promptly send
     copies of all statements, confirmations and other correspondence concerning
     the Designated Accounts and/or any Designated Account Property
     simultaneously to each of the Servicer and the Agent at the addresses set
     forth in the signature pages hereof.

               (b)       The Servicer shall have the right, revocable by the
Agent to notify the Securities Intermediary (with a copy to the Agent) of the
amounts to be withdrawn and paid, and the Securities Intermediary shall make
such withdrawals and payments, from the Designated Accounts for the purpose of
permitting the Servicer to carry out its duties hereunder or permitting the
Agent to carry out its duties hereunder.

               (c)       The Agent shall possess all right, title and interest
in and to all funds on deposit from time to time in the Designated Accounts and
in all proceeds thereof. The Designated Accounts shall be under the sole
dominion and control of the Agent for the benefit of the Agent and the
Purchasers.

               (d)       The Servicer shall not direct the Securities
Intermediary to make any investment of any funds or to sell any investment held
in any of the Designated Accounts unless the security interest granted and
perfected in such account shall continue to be perfected in such investment or
the proceeds of such sale, in either case without any further action by any
Person, and, in connection with any direction to the Agent to make any such
investment or sale, if requested by the Securities Intermediary, the Servicer
shall deliver to the Securities Intermediary an opinion of counsel, acceptable
to the Securities Intermediary, to such effect.

               (e)       The Seller shall pay all fees and expenses of the
Securities Intermediary. The Securities Intermediary shall have no right of
offset against amounts in the Designated Accounts.

          Section 2.8    Default Fees. If any Person fails to pay any of the
                         ------------
Obligations when due, such Person agrees to pay, on demand, the Default Fee in
respect thereof until paid. Notwithstanding the foregoing, no provision of this
Agreement or the Fee Letter shall require the payment or permit the collection
of any amounts hereunder in excess of the maximum permitted by applicable law.

under any clause of Section 2.1(c) or any other provision of this Agreement in
respect of amounts owing to the Agent and the Purchasers shall be allocated and
paid by the Agent to the Purchasers as the Agent and the Purchasers shall agree.

warranties of NFC made to the Seller pursuant to Sections 3.01 and 3.02 of the
                                                 ----------------------
Sale Agreement. The Seller hereby represents and warrants to the Purchasers that

under the Sale Agreement in accepting the Receivables.

                                       15

The foregoing representation and warranty speaks as of the date of this
Agreement, but shall survive the sale, transfer and assignment of the
Receivables to the Purchasers.

                    -------------------------------------------------
discovery by the Seller or the Servicer of a breach of any of the
representations and warranties in Section 3.01 of the Sale Agreement (and, with
                                  ------------

discovery or its receipt of notice of such a breach (or, if a Servicer Default
has occurred and is continuing, or, at the applicable Seller Party's election,
the first Accounting Date following such discovery), unless such breach shall
have been cured in all material respects, the applicable Seller Party shall
repurchase the interests of the Purchasers in such Receivable from the
Purchasers on the related Settlement Date. A Purchaser shall have no affirmative
duty to conduct any investigation as to the occurrence of any event requiring
the repurchase of any Receivable pursuant to this Section 5.1(i).

breach has occurred and is continuing, shall, if such repurchase obligations are
fulfilled, constitute the sole remedy against the Seller, the Servicer or NFC
for such breach available to any Person. The Servicer acknowledges its
obligations to repurchase Administrative Receivables from the Purchaser pursuant
to Section 5.2(b) hereof and to repurchase Warranty Receivables pursuant to
   --------------
Section 5.04 of the Sale Agreement.

               (j)  Corporate Separateness.  Seller will maintain its
                    ----------------------

     acquisition by such dealer or other person of a truck, bus, trailer or
     related equipment that is leased to a third person or persons) from NFC and
     (ii) conducting any ancillary business or activity as it deems necessary or
     appropriate to accomplish its primary purpose. Seller will not amend its

     affiliate of NFC other than Seller. Any financial statements of NFC which
     are presented on a consolidated basis to include Seller shall contain notes
     clearly stating that the Receivables have been sold to a third party and
     are not assets of the consolidated group.

                    (iii)  Seller shall conduct its business solely in its
     individual corporate name and otherwise so as not to mislead others with
     whom it deals regarding its independent identity and existence.

     address, telephone number and stationery.

                    (v)    Seller will cause to be elected and compensate its

     expenses for items shared between Seller on the one hand and NFC on the

     of actual use or value of services rendered and otherwise on a basis
     reasonably related to actual use or the value of services rendered.

                    (vii)  Seller has paid and will pay its own operating
     expenses and liabilities from its own funds, except NFC shall pay a portion
     of the expenses of Seller incurred in connection with the transactions
     contemplated by the Transaction Documents. Such payment by NFC shall be
     treated by NFC as Advances under the Amended and Restated Intercompany
     Advance Agreement (the "Intercompany Advance Agreement") dated as of May 3,
                             ------------------------------
     1994, between NFC and Seller.

                    (viii) Seller shall not commingle or pool its funds or other
     assets with those of NFC or any other subsidiary or affiliate of NFC except
     as specifically provided in transaction documents executed in connection
     with past pools of receivables and in the Amended and Restated Operating
     Agreement dated as of May 3, 1994 (the "Operating Agreement") between NFC
                                             -------------------
     and Seller. Except as provided in the Operating Agreement, Seller shall not
     maintain joint bank accounts or other depository accounts to which NFC or
     any other Affiliate of NFC, other than NFC in its capacity as Servicer, has
     independent access.

                    (ix)   Seller is not named, and has not entered any
     agreement to be named, directly or indirectly, as a direct or contingent
     beneficiary or loss payee on any insurance policy covering the property of
     NFC or of any other subsidiary or Affiliate of NFC.

delinquent or are being diligently contested in good faith by appropriate
proceedings and for which adequate reserves in accordance with generally
accepted accounting principles shall have been set aside on its books.

               (l)  Transfers, Liens, Etc.  Except for the Lien in favor of a
                    ---------------------

               (m)  Liens in Force.  Except as contemplated in Sections 6.1,

otherwise modify any Receivable such that the Initial Receivable Balance, the

such that the final scheduled payment on such Receivable will be due later than
January 31, 2008. Any such extension of the final scheduled payment will be made
by the Servicer in accordance with its customary servicing procedures.

          Section 5.2  Covenants of the Servicer. At all times from the date
                       -------------------------
hereof to the date on which the Aggregate Unpaids shall be equal to zero, unless
the Agent shall otherwise consent in writing:

                  (a)  Conduct of Business.  The Servicer will do all things
                       -------------------
necessary to remain duly incorporated, validly existing and in good standing as
a domestic corporation in its jurisdiction of incorporation and will maintain
all requisite authority to conduct its business in each jurisdiction in which
its business requires such authority except where the failure to so preserve and
maintain or qualify would not result in a Material Adverse Change.

                  (b)  Purchase of Receivables Upon Breach of Covenant.  Upon
                       -----------------------------------------------
discovery by any of the Seller or the Servicer, the Agent and the Purchasers of
a breach of any of the covenants set forth in Section 6.5 and Sections 5.1 (m),
                                              -----------     ----------------
(n) or (o), the party discovering such breach shall give prompt written notice
---    ---
thereof to the Agent and the Purchasers. As of the second Accounting Date
following its discovery or receipt of notice of such breach (or, at the
Servicer's election, the first Accounting Date so following), the Servicer
shall, unless it shall have cured such breach in all material respects, purchase
from the Purchasers their interests in any Receivable materially and adversely
affected by such breach and, on the related Settlement Date, the Servicer shall
pay the Administrative Purchase Payment. It is understood and agreed that the
obligation of the Servicer to purchase any Receivable with respect to which such
a breach has occurred and is continuing shall, if such obligation is fulfilled,
constitute the sole remedy against the Servicer for such breach available to any
Person.

                  (c)  Servicing Procedures.  The Servicer shall not change or
                       --------------------
amend its customary servicing procedures in any manner that would reasonably be
expected to materially and adversely affect the collectibility of the
Receivables generally.

          Section 5.3  Covenant of the Agent.  Until this Agreement has
                       ---------------------

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

"Discount Rate," the Agent, Seller and Servicer will cooperate to have such
Financial Institution replaced with a Financial Institution that would be able
to fund using the LIBO Rate.

<PAGE>

          Section 6.1  General Duties of the Servicer. The Servicer is hereby
                       ------------------------------
appointed and authorized by the Agent and the Purchasers to act as agent for the
Agent and the Purchasers and in such capacity shall manage, service, administer
and make collections on the Receivables with reasonable care using that degree
of skill and attention that the Servicer exercises with respect to comparable
medium and heavy duty truck, bus and trailer receivables that it services for
itself or others. The Servicer hereby accepts such appointment and authorization
and agrees to perform the duties of Servicer with respect to the Receivables set
forth herein. The Servicer's duties shall include collection and posting of all
payments, responding to inquiries of Obligors on the Receivables, investigating
delinquencies, sending payment coupons to Obligors, reporting tax information to
Obligors, policing the collateral, accounting for collections and furnishing
monthly and annual statements to the Purchasers with respect to distributions,
generating federal income tax information and performing the other duties
specified herein. Subject to the provisions of Section 6.2, the Servicer shall
follow its customary standards, policies and procedures and shall have full
power and authority, acting alone, to do any and all things in connection with
such managing, servicing, administration and collection that it may deem
necessary or desirable.

          Without limiting the generality of the foregoing, the Servicer is
hereby authorized and empowered by the Agent and the Purchasers, pursuant to
this Section 6.1, to execute and deliver, on behalf of the Agent and the
     -----------
Purchasers, any and all instruments of satisfaction or cancellation, or of
partial or full release or discharge, and all other comparable instruments, with
respect to the Receivables and the Financed Vehicles. The Servicer is hereby
authorized to commence in the name of the Agent and the Purchasers or, to the
extent necessary, in its own name, a legal proceeding to enforce a Liquidating
Receivable as contemplated by Section 6.3, to enforce all obligations of NFC and
                              -----------
Seller in its capacity as the Seller or otherwise, under each of the Sale
Agreement and this Agreement or to commence or participate in a legal proceeding
(including a bankruptcy proceeding) relating to or involving a Receivable or a
Liquidating Receivable. If the Servicer commences or participates in such a
legal proceeding in its own name, the Agent and the Purchasers shall thereupon
be deemed to have automatically assigned such Receivable to the Servicer for
purposes of commencing or participating in any such proceeding as a party or
claimant. The Servicer is hereby authorized and empowered by the Agent and the
Purchasers to execute and deliver in the Servicer's name any notices, demands,
claims, complaints, responses, affidavits or other documents or instruments in
connection with any such proceeding. The Agent and each Purchaser, upon the
written request of the Servicer, shall furnish the Servicer with any powers of
attorney and other documents and take any other steps which the Servicer may
deem necessary or appropriate to enable the Servicer to carry out its servicing
and administrative duties under this Agreement and the Purchase Agreement.
Except to the extent required by the preceding two sentences, the authority and
rights granted to the Servicer in this Section 6.1 shall be nonexclusive and
                                       -----------
shall not be construed to be in derogation of the retention by the Agent or the
Purchasers of equivalent authority and rights.

          Section 6.2  Collection of Receivables Payments. The Servicer shall
                       ----------------------------------
make reasonable efforts to collect all payments called for under the terms and
provisions of the Receivables as and when the same shall become due, and shall
follow such collection practices, policies and procedures as it follows with
respect to comparable medium and heavy duty truck, bus and trailer receivables
that it services for itself or others. Except as provided in Section 5.1(o), the
                                                             --------------
Servicer is hereby authorized to grant extensions, rebates or adjustments on a
Receivable without the prior consent of the Agent or the Purchasers and to
rewrite, in its ordinary course of business, a Receivable with respect to any
remaining Financed Vehicle or Vehicles to reflect the Full Prepayment of the
portion of such Receivable relating to one or more of the Financed Vehicles
securing such Receivable without the prior consent of the Agent or the
Purchasers. The Servicer is authorized in its discretion to waive any prepayment
charge, late payment charge or any other fees that may be collected in the
ordinary course of servicing the Receivables.

          Section 6.3  Realization Upon Liquidating Receivables. The Servicer
                       ----------------------------------------
shall use reasonable efforts, consistent with its customary servicing
procedures, to repossess or otherwise comparably convert the ownership of each
Financed Vehicle that it has reasonably determined should be repossessed or
otherwise converted following a default under the Receivable secured by each
such Financed Vehicle. The Servicer is authorized to follow such practices,
policies and procedures as it shall deem necessary or advisable and as shall be
customary and usual in its servicing of medium and heavy duty truck, bus and
trailer receivables that it services for itself or others, which practices,
policies and procedures may include reasonable efforts to realize upon or obtain
benefits of any lease assignments, proceeds from any Dealer Liability, proceeds
from any International Purchase Obligations, proceeds from any Insurance
Policies and proceeds from any Guaranties, in each case with respect to the
Receivables, selling the related Financed Vehicle or Financed Vehicles at public
or private sale or sales and other actions by the Servicer in order to realize
upon such a Receivable. The foregoing is subject to the provision that, in any
case in which the Financed Vehicle shall have suffered damage, the Servicer
shall not be required to expend funds in connection with any repair or towards
the repossession of such Financed Vehicle unless it shall determine in its
discretion that such repair and/or repossession is reasonably likely to increase
the proceeds of liquidation of the related Receivable by an amount greater than
the amount of such expenses. The Servicer shall be entitled to receive
Liquidation Expenses from Collections with respect to each Liquidating
Receivable at such time as the Receivable becomes a Liquidating Receivable in
accordance with Section 2.1(b). Following the occurrence and continuation of a
                --------------
Servicer Default, the Agent may, but shall have no obligation to take any action
or commence any proceeding to realize upon any Liquidating Receivable, any such
action or commencement of proceeding to be at the sole expense of the Servicer.
At such time as the Servicer or the Seller, as the case may be, has any
obligation to pursue the collection of Receivables and the Agent or a Purchaser
possesses any documents necessary therefor, the Agent or such Purchaser, as the
case may be, agrees to furnish such documents to the Servicer or the Seller, as
the case may be, to the extent and for the period necessary for the Servicer or
the Seller, as the case may be, to comply with its obligations hereunder.

          Section 6.4  Maintenance of Insurance Policies. The Servicer shall, in
                       ---------------------------------
accordance with its customary servicing procedures, require that each Obligor
shall have obtained physical damage insurance covering each Financed Vehicle as
of the execution of the related Receivable, unless the Servicer has in
accordance with its customary servicing procedures permitted an Obligor to self-
insure the Financed Vehicle or Financed Vehicles securing such Receivable. The
Servicer shall, in accordance with its customary servicing procedures, monitor
such physical damage insurance with respect to each Financed Vehicle that
secures each Receivable.

          Section 6.5  Maintenance of Security Interests in Vehicles. The
                       ---------------------------------------------
Servicer shall, in accordance with its customary servicing procedures and at its
own expense, take such steps as are necessary to maintain perfection of the
first priority security interest created by each Receivable in the related
Financed Vehicle or Financed Vehicles. The Purchasers hereby authorize the
Servicer to re- perfect such security interest as necessary because of the
relocation of a Financed Vehicle or for any other reason.

          Section 6.6  Total and Supplemental Servicing Fees; Payment of Certain
                       ---------------------------------------------------------
Expenses by Servicer. The Servicer is entitled to receive the Total Servicing
--------------------
Fee and Supplemental Servicing Fees out of Collections as provided herein.
Subject to any limitation on the Servicer's liability hereunder, the Servicer
shall be required to pay all expenses incurred by it in connection with its
activities under this Agreement (including fees and disbursements of the
Purchaser, the Financial Institution, the Agent, and any independent
accountants, taxes imposed on the Servicer, expenses incurred in connection with
distributions and reports to the Agent and the Purchasers and all other fees and
expenses not expressly stated under this Agreement to be for the account of the
Purchasers, but excluding federal, state and local income and franchise taxes,
if any, of any Purchaser). The Servicer will not have any obligation to deposit
Supplemental Servicing Fees in the Collection Account. To the extent that any
such amount shall be held in the Collection Account, such amount may be
withdrawn therefrom by the Servicer.

          Section 6.7  Monthly Advances. Subject to the following sentence, as
                       ----------------
of each Settlement Date, if the payments during the related Monthly Period by or
on behalf of the Obligor on a Receivable (other than an Administrative
Receivable, a Warranty Receivable or a Liquidating Receivable) after application
under Section 2.1 shall be less than the Scheduled Payment, whether as a result
      -----------
of any extension granted to the Obligor or otherwise, then the Servicer shall,
subject to the following sentence, advance any such shortfall (such amount, a
"Monthly Advance"). The Servicer shall be obligated to make a Monthly Advance in
 ---------------
respect of a Receivable only to the extent that the Servicer, in its sole
discretion, shall determine that such advance shall be recoverable (in
accordance with the two immediately following sentences) from subsequent
Collections or recoveries on such Receivable. Subject to Section 2.1, the
                                                         -----------
Servicer shall be reimbursed for Outstanding Monthly Advances with respect to a
Receivable from the following sources with respect to such Receivable, in each
case as set forth in this Agreement: (i) subsequent payments by or on behalf of
the Obligor, (ii) collections of Liquidation Proceeds, (iii) the Administrative
Purchase Payment and (iv) the Warranty Payment. At such time as the Servicer
shall determine that any Outstanding Monthly Advances with respect to any
Receivable shall not be recoverable from

                                       22
<PAGE>

payments with respect to such Receivable, the Servicer shall be reimbursed from
any collections made on other Receivables.

          Section 6.8   Additional Deposits. The Servicer shall deposit in the
                        -------------------
Collection Account the aggregate Monthly Advances pursuant to this Section 6.7.
                                                                   -----------
The Servicer and the Warranty Purchaser shall deposit in the Collection Account
the aggregate Administrative Purchase Payments and Warranty Payments with
respect to Administrative Receivables and Warranty Receivables, respectively.
All such deposits with respect to a Monthly Period shall be made in immediately
available funds on the day before the Settlement Date related to such Monthly
Period.

          Section 6.9   Annual Statement as to Compliance. The Servicer shall
                        ---------------------------------
deliver to the Agent on or before February 1 of each year, beginning February 1,
2002, an officer's certificate signed by the President or any Vice President of
the Servicer, dated as of the immediately preceding October 31, stating that (i)
a review of the activities of the Servicer during the preceding 12-month period
(or, with respect to the first such certificate, such period as shall have
elapsed from the date of this Agreement to the date of such certificate) and of
its performance under this Agreement has been made under such officer's
supervision and (ii) to such officer's knowledge, based on such review, the
Servicer has fulfilled its obligations under this Agreement in all material
respects throughout such period, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to such
officer and the nature and status thereof.

          Section 6.10  Annual Independent Accountants' Report.
                        --------------------------------------

               (a)      The Servicer shall cause a firm of independent
accountants, who may also render other services to the Servicer or the Seller,
to deliver to the Agent, on or before February 1 of each year, beginning
February 1, 2002 with respect to the twelve months ended on the immediately
preceding October 31 (or, with respect to the first such report, such period as
shall have elapsed from the date of this Agreement to the date of such
certificate), a report (the "Accountants' Report") addressed to the board of
                             -------------------
directors of the Servicer and to the Agent, to the effect that such firm has
audited the financial statements of the Servicer and issued its report thereon
and that such audit (i) was made in accordance with generally accepted auditing
standards, (ii) included tests relating to retail notes serviced for others in
accordance with the requirements of the Uniform Single Audit Program for
Mortgage Bankers (the "Program,") to the extent the procedures in the Program
                       -------
are applicable to the servicing obligations set forth in this Agreement and
(iii) except as described in the report, disclosed no exceptions or errors in
the records relating to retail notes serviced for others that, in the firm's
opinion, paragraph four of the Program requires such firm to report.

               (b)      The Accountants' Report shall also indicate that the
firm is independent of the Seller and the Servicer within the meaning of the
Code of Professional Ethics of the American Institute of Certified Public
Accountants.

          Section 6.11  Assignment of Administrative Receivables and Warranty
                        -----------------------------------------------------
Receivables. Upon receipt of the Administrative Purchase Payment or the Warranty
Payment with respect to an Administrative Receivable or a Warranty Receivable,
respectively, the Agent, on behalf of the Purchasers, shall assign, without
recourse, representation or warranty, to the Servicer or the Warranty Purchaser,
as applicable, all of such Person's right, title and interest in, to and under
(a) such Administrative Receivable or Warranty Receivable and all monies due
thereon, (b) the security interests in the related Financed Vehicle and, to the
extent permitted by law, any accessions thereto which are financed by NFC, (c)
benefits of any lease assignments with respect to the Financed Vehicles, (d)
proceeds from any Insurance Policies with respect to such Receivable, (e)
proceeds from Dealer Liability with respect to such Receivable, proceeds from
any International Purchase Obligations with respect to such Receivable and
proceeds from any Guaranties of such Receivable, (f) the interests of such
Person in certain rebates of premiums and other amounts relating to the
Insurance Policies and any document relating thereto and (g) the rights of such
Person under the Purchase Agreement and the Custodian Agreement with respect to
such Receivable, such assignment being an assignment outright and not for
security. Upon the assignment of such Receivable described in the preceding
sentence, the Servicer or the Warranty Purchaser, as applicable, shall own such
Receivable, and all such security and documents, free of any further obligations
to the Agent or any Purchaser with respect thereto. If in any Proceeding it is
held that the Servicer may not enforce a Receivable on the grounds that it is
not a real party in interest or a holder entitled to enforce the Receivable, the
Agent shall, at the Servicer's expense, take such steps as the Servicer deems
necessary to enforce the Receivable, including bringing suit in the name of such
Person or the names of the Purchasers.

          Section 6.12  Collection Account. The Servicer shall maintain, for the
                        ------------------
benefit of the Agent and the Purchasers, the Collection Account for the purpose
of receiving and disbursing all Collections, and all other payments to be made
into the Collection Account. The Collection Account will be an Eligible Account
maintained in the name of the Agent, for the benefit of the Agent and the
Purchasers, and shall be used only for the collection of the amounts and for
application of such amounts as described in Section 1.4(c) of this Agreement. In
the event there shall have been deposited in the Collection Account any amount
not required to be deposited therein and so identified to the Agent, such amount
shall be withdrawn from the Collection Account by the Securities Intermediary
after notice thereof by the Servicer to the Securities Intermediary (with a copy
to the Agent) and the Securities Intermediary shall pay such amount to or in
accordance with the instructions of the Servicer, and any such amounts shall not
be deemed to be a part of the Collection Account. If the Collection Account
ceases to be an Eligible Account, the Agent shall, within ten days of receipt of
notice of such change in eligibility, transfer the Collection Account to an
account meeting the requirements of an Eligible Account.

          The Servicer and the Seller agree to take all actions reasonably
necessary, including the filing of appropriate financing statements and the
giving of proper registration instructions relating to any investments, to
protect the Agent's and the Purchasers' interest in the Collection Account and
any Eligible Investments acquired with moneys therein.

          Section 6.13  Delegation of Duties. So long as NFC acts as Servicer,
                        --------------------
the Servicer may, at any time without notice or consent, delegate any duties
under this Agreement to any corporation more than 50% of the voting stock of
which is owned, directly or indirectly, by NFC. The Servicer may at any time
perform specific duties as Servicer through sub-contractors who are in the
business of servicing medium and heavy duty truck, bus and trailer receivables;
provided, however, that no such delegation shall relieve the Servicer of its
--------  -------
responsibility with respect to such duties.

          Section 6.14  Servicer Not to Resign. Subject to the provisions of
                        ----------------------
Section 7.2, the Servicer shall not resign from the obligations and duties
-----------
imposed on it by this Agreement as Servicer except upon determination that the
performance of its duties under this Agreement is no longer permissible under
applicable law. Any such determination permitting the resignation of the
Servicer shall be evidenced by an opinion of counsel to such effect delivered to
the Agent. No such resignation shall become effective until the Agent, its
designee or a successor Servicer shall have assumed the responsibilities and
obligations of the Servicer in accordance with Section 6.15.
                                               ------------

          Section 6.15  Appointment of Successor. On and after the time the
                        ------------------------
Servicer receives a notice of termination and the appointment of a successor
Servicer pursuant to Section 7.2, such successor Servicer shall be the successor
                     -----------
in all respects to the Servicer in its capacity as servicer under this Agreement
and the transactions set forth or provided for in this Agreement; provided
                                                                  --------
however, that the predecessor Servicer shall remain liable for, and the
-------
successor Servicer shall have no liability for, any indemnification obligations
of the Servicer arising as a result of acts, omissions or occurrences during the
period in which the predecessor Servicer was the Servicer; and provided further,
                                                               -------- -------
that NFC shall remain liable for all such indemnification obligations of the
Servicer without regard to whether it is still Servicer hereunder. As
compensation therefor, the successor Servicer shall be entitled to such
compensation (whether payable out of the Collection Account or otherwise) as the
predecessor Servicer would have been entitled to under this Agreement if no such
notice of termination had been given including, but not limited to, the Total
Servicing Fee and Supplemental Servicing Fees; provided, however, in the event
the Agent shall be unable to appoint a successor Servicer reasonably acceptable
to the Agent for the compensation specified herein, the Agent may make such
arrangements for compensation of such successor Servicer out of payments on the
Receivables as it and such successor Servicer shall agree provided that such
compensation shall not exceed 110% of such successor Servicer's reasonable costs
and expenses in performing its obligations hereunder as successor Servicer.

merged or consolidated, (b) resulting from any merger, conversion or
consolidation to which the Servicer shall be a party, (c) succeeding to the
business of the Servicer, or (d) more than 50% of the voting stock of which is

          Section 7.1  Servicer Defaults. The occurrence of any one or more of

representation, warranty, certification or statement not misleading);

               (e)     the entry of a decree or order by a court or agency or

          Section 7.2  Remedies.
                       --------

               (a)     If a Servicer Default shall occur and be continuing, the
Agent by notice then given in writing to the Servicer may, in addition to other
rights and remedies available in a court of law or equity to damages, injunctive
relief and specific performance, terminate all of the rights and obligations of
the Servicer under this Agreement ("Servicing Transfer"). On or after the
                                    ------------------
receipt by the Servicer of such written notice, all authority and power of the
Servicer under this Agreement, whether with respect to the Receivables or
otherwise, shall pass to and be vested in a successor Servicer appointed by the
Agent pursuant to and under this Section 7.2. The successor Servicer is hereby
                                 -----------
authorized and empowered to execute and deliver, on behalf of the predecessor
Servicer, as attorney-in- fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement of the Receivables and related documents,
or otherwise. The predecessor Servicer agrees to cooperate with the successor
Servicer and the Agent in effecting the termination of the responsibilities and
rights of the predecessor Servicer under this Agreement, including the transfer
to the successor Servicer for administration by it of all cash amounts that
shall at the time be held by the predecessor Servicer for deposit, or that shall
have been deposited by the predecessor Servicer in the Collection Account or the
Reserve Account or thereafter received with respect to the Receivables that
shall at that time be held by the predecessor Servicer. In addition to any other
amounts that are then payable to the predecessor Servicer under this Agreement,
the predecessor Servicer shall be entitled to receive from the successor
Servicer reimbursements for any Outstanding Monthly Advances made during the
period prior to the termination of the predecessor Servicer as Servicer pursuant
to this Section 7.2.
        -----------

               (b)     The predecessor Servicer shall, within two (2) Business
Days after receiving a notice pursuant to Section 7.2(a) hereof, at the
                                          --------------
Servicer's sole expense, permit the successor Servicer and the Agent access to
NFC's files and other records in order to effect an orderly transfer of
servicing.

<PAGE>

               (c)     If at any time there shall be a Servicing Transfer, NFC
will cause to be transmitted and delivered directly to the successor Servicer,
forthwith upon receipt and in the exact form received, all Collections (properly
endorsed, where required, so that such items may be collected by the successor
Servicer) on account of the Purchaser Interest. All such Collections consisting
of cash shall not be commingled with other items or monies of NFC for a period
longer than two Business Days. If the Agent or successor Servicer receives items
or monies that are not payments on account of the Purchasers' interest in any
Receivables, such items or monies shall be held in trust by the Agent or
successor Servicer, as applicable, for the Seller's benefit and delivered
promptly to NFC after being so identified by the Agent or the successor
Servicer.

               (d)     At any time, and from time to time following a Servicing
Transfer, the successor Servicer shall be entitled to notify the Obligors to
make payments directly to the successor Servicer of amounts due under the
Receivables at any time and from time to time.

                                INDEMNIFICATION

          Section 8.1  Indemnities by the Seller Parties. Without limiting any
                       ---------------------------------
other rights that the Agent or any Purchaser may have hereunder or under
applicable law, (A) the Seller hereby agrees to indemnify (and pay upon demand
to) the Agent and each Purchaser and their respective assigns, officers,
directors, agents and employees (each an "Indemnified Party") from and against
                                          -----------------
any and all damages, losses, claims, taxes, liabilities, costs, expenses and for
all other amounts payable, including reasonable attorneys' fees (which attorneys
may be employees of the Agent or such Purchaser) and disbursements (all of the
foregoing being collectively referred to as "Indemnified Amounts") awarded
                                             -------------------
against or incurred by any of them arising out of or as a result of this
Agreement or the acquisition, either directly or indirectly, by a Purchaser of
an interest in the Receivables, and (B) the Servicer hereby agrees to indemnify
(and pay upon demand to) each Indemnified Party for Indemnified Amounts awarded
against or incurred by any of them arising out of the Servicer's activities as
Servicer hereunder excluding, however, in all of the foregoing instances under
the preceding clauses (A) and (B):
              -------------------

                       (i)    Indemnified Amounts to the extent such Indemnified
     Amounts resulted from gross negligence or willful misconduct on the part of
     the Indemnified Party seeking indemnification;

                       (ii)   Indemnified Amounts to the extent arising from the
     acts or omissions of a successor Servicer;

     includes losses in respect of Receivables that are uncollectible; or

                                       28
<PAGE>

                       (iv)   taxes imposed by any jurisdiction in which such
     Indemnified Party is or would be subject to tax (unless such tax arises
     solely as a result of the transactions contemplated by this Agreement) on
     or measured by the overall net income of such Indemnified Party to the
     extent that the computation of such taxes is consistent with the
     characterization for income tax purposes of the acquisition by the
     Purchasers of interests in the Purchaser Interest as a loan or loans by the
     Purchasers to Seller secured by the Receivables, the Related Security, and
     the Designated Accounts;

provided, however, that nothing contained in this sentence shall limit the
--------  -------
liability of any Seller Party or limit the recourse of the Purchasers to any
Seller Party for amounts otherwise specifically provided to be paid by such
Seller Party under the terms of this Agreement.

Without limiting the generality of the foregoing indemnification, Seller shall
indemnify the Agent and the Purchasers for Indemnified Amounts (including,
without limitation, losses in respect of uncollectible receivables, regardless
of whether reimbursement therefor would constitute recourse to Seller or the
Servicer) relating to or resulting from:

               (a)     any representation or warranty made by any Seller Party
or the Originator (or any officers of any such Person) under or in connection
with this Agreement, any other Transaction Document or any other information or
report delivered by any such Person pursuant hereto or thereto, which shall have
been false or incorrect when made or deemed made;

               (b)     the failure by Seller, the Servicer or the Originator to
comply with any applicable law, rule or regulation with respect to any
Receivable or Contract related thereto, or the nonconformity of any Receivable
or Contract included therein with any such applicable law, rule or regulation or
any failure of the Originator to keep or perform any of its obligations, express
or implied, with respect to any Contract;

               (c)     any failure of Seller, the Servicer or the Originator to
perform its duties, covenants or other obligations in accordance with the
provisions of this Agreement or any other Transaction Document;

               (d)     any products liability, personal injury or damage suit,
or other similar claim arising out of or in connection with merchandise,
insurance or services that are the subject of any Contract or any Receivable;

               (e)     any dispute, claim, counterclaim, offset or defense
(other than discharge in bankruptcy of the Obligor) of the Obligor to the
payment of any Receivable (including, without limitation, a defense based on
such Receivable or the related Contract not being a legal, valid and binding
obligation of such Obligor enforceable against it in accordance with its terms),
or any other claim resulting from the sale of the merchandise or service related
to such Receivable or the furnishing or failure to furnish such merchandise or
services;

with other funds;

               (g)     any investigation, litigation or proceeding related to or
arising from this Agreement or any other Transaction Document, the transactions
contemplated hereby, the use of the proceeds of a purchase, the ownership of the
Purchaser Interest or any other investigation, litigation or proceeding relating
to Seller, the Servicer or the Originator in which any Indemnified Party becomes
involved as a result of any of the transactions contemplated hereby;

               (h)     any inability to litigate any claim against any Obligor
in respect of any Receivable as a result of such Obligor being immune from civil
and commercial law and suit on the grounds of sovereignty or otherwise from any
legal action, suit or proceeding;

               (i)     any failure of Seller to acquire and maintain legal and
equitable title to, and ownership of any Receivable and the Related Security and
Collections with respect thereto from the Originator, free and clear of any
Adverse Claim (other than as created hereunder); or any failure of Seller to
give reasonably equivalent value to the Originator under the Receivables Sale
Agreement in consideration of the transfer by the Originator of any Receivable,
or any attempt by any Person to void such transfer under statutory provisions or
common law or equitable action;

               (j)     any failure to vest and maintain vested in the Agent for
the benefit of the Purchasers, or to transfer to the Agent for the benefit of
the Purchasers, legal and equitable title to, and ownership of, a first priority
perfected undivided ownership interest (to the extent of the Purchaser Interest
contemplated hereunder) or security interest in the Receivables and the Related
Security free and clear of any Adverse Claim (except as created by the
Transaction Documents);

               (k)     the failure to have filed, or any delay in filing,
financing statements or other similar instruments or documents under the UCC of
any applicable jurisdiction or other applicable laws with respect to any
Receivable and the Related Security;

               (l)     any action or omission by any Seller Party which reduces
or impairs the rights of the Agent or the Purchasers with respect to any
Receivable or the value of any such Receivable;

               (m)     any attempt by any Person to void the purchase of the
Purchaser Interest hereunder under statutory provisions or common law or
equitable action; and

               (n)     any claim by any party arising from the activities of the
Seller or Servicer in administering, servicing or collecting any Receivable.

of its obligations under a Funding Agreement, or to reduce the amount of any sum
received or receivable by a Financial Institution under a Funding Agreement or

shall pay to the Agent, for the benefit of the relevant Financial Institution,
such amounts charged to such Financial Institution or such amounts to otherwise
compensate such Financial Institution for such increased cost or such reduction.

however, that (i) Seller shall be liable to each Purchaser and the Agent for all
representations, warranties, covenants and indemnities made by Seller pursuant

person arising in connection with the Receivables, the Related Security, or the
related Contracts, or any other obligations of Seller or the Originator.
However, notwithstanding the foregoing, the parties will treat the transactions

time as funds are available therefor thereunder from the Receivables, the
Related Security, the Collections, the Designated Accounts and the other rights
transferred to the Seller pursuant to the Sale Agreement or specified in this
Agreement, and, to the extent funds are not so available to pay such
