     THIS POOLING AND SERVICING AGREEMENT is made as of November 1, 2001 by and
among Navistar Financial Corporation, a Delaware corporation ("NFC" and, in its
capacity as Servicer hereunder, the "Servicer"), Navistar Financial Retail
Receivables Corporation, a Delaware corporation ("NFRRC" and, in its capacity as
the Seller hereunder, the "Seller"), and Chase Manhattan Bank USA, National
Association, a national banking association, not in its individual capacity, but
solely as Owner Trustee under the Trust Agreement (the "Owner Trustee").

     WHEREAS, NFC has sold the Initial Receivables, and has agreed to sell
Subsequent Receivables, to the Seller pursuant to the Purchase Agreement.

     WHEREAS, the Seller desires to sell the Initial Receivables and Subsequent
Receivables (collectively, the "Receivables"), to the Owner Trustee in exchange
for the Securities and the payment of funds withdrawn from the Pre-Funding
Account pursuant to the terms of this Agreement, and the Servicer desires to
perform the servicing obligations set forth herein for and in consideration of
the fees and other benefits set forth in this Agreement.

     WHEREAS, the Seller and the Owner Trustee wish to set forth the terms
pursuant to which the Receivables are to be sold by the Seller to the Owner
Trustee on behalf of the Trust and serviced by the Servicer.

     NOW, THEREFORE, in consideration of the foregoing, the other good and
valuable consideration and the mutual terms and covenants contained herein, the
parties hereto agree as follows:

                                    ARTICLE I
                                   DEFINITIONS

<PAGE>

     SECTION 2.1. Conveyance of Initial Receivables. In consideration of the
                   ---------------------------------
Owner Trustee's delivery of the Securities to, or upon the order of, the Seller,
the Seller does hereby enter into this Agreement and agree to fulfill all of its
obligations hereunder and to sell, transfer, assign, set over and otherwise
convey to Chase Manhattan Bank USA, National Association, not in its individual
capacity, but solely as Owner Trustee, under the Trust Agreement, without
                                                                  -------
recourse, pursuant to an assignment in the form attached hereto as Exhibit B
--------                                                           ---------
(the "Initial PSA Assignment"), all right, title and interest of the Seller in,
to and under:

     (a) the Initial Receivables and all monies paid thereon (including
Liquidation Proceeds) and due thereunder on and after the Initial Cutoff Date;

     (b) the security interests in the Financed Vehicles granted by Obligors
pursuant to the Initial Receivables and, to the extent permitted by law, any
accessions thereto which are financed by NFC;

     (c) the benefits of any lease assignments with respect to the related
Financed Vehicles;

     (d) any proceeds from any Insurance Policies with respect to the Initial
Receivables;

     (e) any proceeds from Dealer Liability with respect to the Initial
Receivables, proceeds from any International Purchase Obligations with respect
to the Initial Receivables (subject to the limitations set forth in Section
2.04) and proceeds from any Guaranties of Initial Receivables;

     (f) the Purchase Agreement, the Initial PA Assignment pursuant to Section
2.01 of the Purchase Agreement with respect to the Initial Receivables, and the
Custodian Agreement, including the right of the Seller to cause NFC to perform
its obligations thereunder (including the obligation to repurchase Initial
Receivables under certain circumstances); and

     (g) any proceeds of the property described in clauses (a), (b), (c) and (f)
above.

It is the intention of the Seller that the transfer and assignment contemplated
by this Section 2.01 shall constitute a sale of the Initial Receivables from the
Seller to the Owner Trustee, on behalf of the Trust, and the beneficial interest
in and title to the assets conveyed pursuant to this Section 2.01 shall not be
part of the Seller's estate in the event of the filing of a bankruptcy petition
by or against the Seller under any bankruptcy law. Within two Business Days
after the Closing Date, the Seller shall cause to be deposited into the
Collection Account all collections (from whatever source) on or with respect to
the assets conveyed pursuant to this Section 2.01 received by the Seller
pursuant to Section 5.07 of the Purchase Agreement. The Seller and the Servicer
intend to treat such transfer and assignment as a sale for accounting and tax
purposes. Notwithstanding the foregoing, in the event a court of competent
jurisdiction determines that such transfer and assignment did not constitute
such a sale or that such beneficial interest is a part of the Seller's estate,
then (i) the Seller shall be deemed to have granted to the Owner Trustee, on
behalf of the Trust, a first priority perfected security interest in all of the
Seller's right title and interest in, to and under the assets conveyed pursuant
to this Section 2.01, and the Seller hereby grants such security interest and
(ii) the

                                       2

assets conveyed pursuant to this Section 2.01 shall be deemed to include all
rights, powers and options (but none of the obligations, if any) of the Seller
under any agreement or instrument included in the assets conveyed pursuant to
this Section 2.01, including the immediate and continuing right to claim for,
collect, receive and give receipt for principal and interest payments in respect
of the Initial Receivables included in the assets conveyed pursuant to this
Section 2.01 and all other monies payable under the Initial Receivables conveyed
pursuant to this Section 2.01, to give and receive notices and other
communications, to make waivers or other agreements, to exercise all rights,
powers and options, to bring Proceedings in the name of the Seller or otherwise
and generally to do and receive anything that the Seller is or may be entitled
to do or receive under or with respect to the assets conveyed pursuant to this
Section 2.01. For purposes of such grant, this Agreement shall constitute a
security agreement under the UCC.

     SECTION 2.2. Conveyance of Subsequent Receivables. (a) Subject to
                   ------------------------------------
satisfaction of the conditions set forth in Section 2.02(b) below, in
consideration of the Owner Trustee's delivery on the related Subsequent Transfer
Date to or upon the order of the Seller of the amount described in Section
5.02(a) to be delivered to the Seller, the Seller does hereby agree to sell,
transfer, assign, set over and otherwise convey to the Owner Trustee, without
                                                                      -------
recourse, pursuant to an assignment in substantially the form of Exhibit C (a
--------                                                         ---------
"Subsequent Transfer PSA Assignment"), all right, title and interest of the
Seller in, to and under:

          (i)   the Subsequent Receivables described in such Subsequent Transfer
     PSA Assignment and identified on the Schedule of Receivables and all monies
     paid thereon (including Liquidation Proceeds) and due thereunder on and
     after the applicable Subsequent Cutoff Date;

          (ii)  the security interests in the Financed Vehicles granted by
     Obligors pursuant to such Subsequent Receivables and, to the extent
     permitted by law, any accessions thereto which are financed by NFC;

          (iii) the benefits of any lease assignments with respect to the
     related Financed Vehicles;

          (iv)  any proceeds from any Insurance Policies with respect to such
     Subsequent Receivables;

          (v)   any proceeds from Dealer Liability with respect to such
     Subsequent Receivables, proceeds from any International Purchase
     Obligations with respect to such Subsequent Receivables (subject to the
     limitations set forth in Section 2.04) and proceeds from any Guaranties of
     Subsequent Receivables;

          (vi)  the Purchase Agreement, the Subsequent Transfer PA Assignments
     pursuant to Section 2.01 of the Purchase Agreement with respect to such
     Subsequent Receivables and the Custodian Agreement, including the right of
     the Seller to cause NFC to perform its

                                       3

<PAGE>

     obligations thereunder (including the obligation to repurchase Subsequent
     Receivables under certain circumstances); and

          (vii)  any proceeds of the property described in clauses (i),
     (ii), (iii) and (vi) above.

It is the intention of the Seller that each transfer and assignment contemplated
by this Section 2.02 shall constitute a sale of the related Subsequent
Receivables from the Seller to the Owner Trustee and the beneficial interest in
and title to the assets conveyed pursuant to the Subsequent Transfer PSA
Assignment shall not be part of the Seller's estate in the event of the filing
of a bankruptcy petition by or against the Seller under any bankruptcy law.
Within two Business Days after each Subsequent Transfer Date, the Seller shall
cause to be deposited into the Collection Account all collections (from whatever
source) on or with respect to the assets conveyed pursuant to the related
Subsequent Transfer PSA Assignment received by the Seller pursuant to Section
5.07 of the Purchase Agreement. The Seller and the Servicer intend to treat each
such transfer and assignment as a sale for accounting and tax purposes.
Notwithstanding the foregoing, in the event a court of competent jurisdiction
determines that any such transfer and assignment did not constitute such a sale
or that such beneficial interest is a part of the Seller's estate, then (i) the
Seller shall be deemed to have granted to the Owner Trustee a first priority
perfected security interest in all of the Seller's right, title and interest in,
to and under the assets conveyed pursuant to the related Subsequent Transfer PSA
Assignment, and the Seller hereby grants such security interest and (ii) the
assets conveyed pursuant to such Subsequent Transfer PSA Assignment shall be
deemed to include all rights, powers and options (but none of the obligations,
if any) of the Seller under any agreement or instrument included in the assets
conveyed pursuant to such Subsequent Transfer PSA Assignment, including the
immediate and continuing right to claim for, collect, receive and give receipt
for principal and interest payments in respect of the Subsequent Receivables
included in the assets conveyed pursuant to such Subsequent Transfer PSA
Assignment and all other monies payable under the Subsequent Receivables
conveyed pursuant to such Subsequent Transfer PSA Assignment, to give and
receive notices and other communications, to make waivers or other agreements,
to exercise all rights, powers and options, to bring Proceedings in the name of
the Seller or otherwise and generally to do and receive anything that the Seller
is or may be entitled to do or receive under or with respect to the assets
conveyed pursuant to such Subsequent Transfer PSA Assignment. For purposes of
such grant, each such Subsequent Transfer PSA Assignment, together with this
Agreement, shall constitute a security agreement under the UCC.

          (b)    The Seller shall transfer to the Owner Trustee Subsequent
Receivables and the other property and rights related thereto described in
Section 2.02(a) above only upon the satisfaction of each of the following
conditions precedent on or prior to the related Subsequent Transfer Date:

          (i)    the Funding Period shall not have terminated;

          (ii)   each of the representations and warranties made by the Seller
     pursuant to Section 2.05 with respect to such Subsequent Receivables shall
     be true and correct as of the related Subsequent Transfer Date with the
     same effect as if then made, and the Seller shall

                                       4

<PAGE>

          have performed all obligations to be performed by it hereunder on or
          prior to such Subsequent Transfer Date;

               (iii)  the Seller shall have delivered to the Owner Trustee, the
          Indenture Trustee and the Rating Agencies a duly executed Subsequent
          Transfer PSA Assignment, including a schedule of such Subsequent
          Receivables (which schedule shall be deemed to supplement the Schedule
                                                                        --------
          of Receivables in effect at such time);
          --------------
               (iv)   the applicable Reserve Account Subsequent Transfer Deposit
          for such Subsequent Transfer Date shall have been deposited in the
          Reserve Account pursuant to Section 5.02(a)(ii);

               (v)    the Seller shall, at its own expense, on or prior to each
          Subsequent Transfer Date indicate in its computer files that the
          Subsequent Receivables conveyed on such date have been sold to the
          Owner Trustee pursuant to this Agreement and the related Subsequent
          Transfer PSA Assignment;

               (vi)   the Seller shall have taken any action required to
          maintain the first priority perfected ownership interest of the Owner
          Trustee in the Owner Trust Estate and the first priority perfected
          security interest of the Indenture Trustee in the Collateral;

               (vii)  The Receivables in the Trust (after giving effect to the
          conveyance of the Subsequent Receivables to the Trust on such
          Subsequent Transfer Date) shall meet the following criteria: (A) the
          weighted average Annual Percentage Rate of the Receivables in the
          Trust shall not be less than 8.12%, (B) the weighted average remaining
          maturity of the Receivables in the Trust shall not be greater than 55
          months and (C) the aggregate Receivables Balance of all Receivables
          owing from a single Obligor shall not be more than 2.00% of the
          aggregate Receivables Balance of all Receivables in the Trust;

               (viii) the Seller shall have delivered to the Indenture Trustee
          and the Owner Trustee an Officers' Certificate confirming the
          satisfaction of the conditions specified in this Section 2.02(b);

               (ix)   the Seller shall have delivered to the Rating Agencies an
          Opinion of Counsel with respect to the transfer of such Subsequent
          Receivables substantially in the form of the Opinion of Counsel
          delivered to the Rating Agencies on the Closing Date;

               (x)    The Seller shall have delivered to the Owner Trustee and
          the Indenture Trustee written confirmation from an independent public
          accounting firm that, as of the applicable Subsequent Cutoff Date,
          such Subsequent Receivables satisfied the eligibility criteria
          described in Sections 3.01(a)(v), (r), (s), (t), (w) and (x) of the
          Purchase Agreement; and

                                       5

<PAGE>

                (xi)  S&P shall have notified the Seller in writing that,
         following the addition of all such Subsequent Receivables to the Trust,
         the Notes will be rated by S&P in the same rating category as they were
         rated by S&P prior to such addition.

                (c)   The Seller covenants to transfer to the Owner Trustee
pursuant to Section 2.02(a) before the termination of the Funding Period,
Subsequent Receivables with an aggregate Starting Receivable Balance equal to
$207,670,906.02. If on the Distribution Date on which the Funding Period ends
(or, if the Funding Period does not end on a Distribution Date, the first
Distribution Date following the end of the Funding Period) the Pre-Funded Amount
is equal to or greater than $100,000, the Seller shall be obligated to pay to
the Owner Trustee on the Transfer Date immediately preceding such Distribution
Date an amount equal to the Noteholders' Prepayment Premium with respect to each
class of Notes or such lesser amount that the Seller actually receives from NFC
under Section 2.04 of the Purchase Agreement in respect of NFC's breach thereof;
provided, however, that the foregoing shall be the sole remedy of the Owner
--------  -------
Trustee, the Indenture Trustee and the Noteholders with respect to a failure of
the Seller to comply with this covenant.

         SECTION 2.3. Custody of Receivable Files. In connection with the sale,
                      ---------------------------
transfer and assignment of Receivables to the Seller from NFC pursuant to the
Purchase Agreement, the Seller, simultaneously with the execution and delivery
of this Agreement, shall enter into the Custodian Agreement with the Custodian,
pursuant to which the Seller shall revocably appoint the Custodian, and the
Custodian shall accept such appointment, to act as the agent of the Seller as
Custodian of the following documents or instruments which shall be
constructively delivered to the Owner Trustee, as of the Closing Date with
respect to each Initial Receivable, and as of the related Subsequent Transfer
Date with respect to each Subsequent Receivable:

         (a)    the fully executed original of the Retail Note for such
Receivable;

         (b)    documents evidencing or related to any Insurance Policy;

         (c)    the original credit application of each Obligor, fully executed
by each such Obligor on NFC's customary form, or on a form approved by NFC, for
such application;

         (d)    where permitted by law, the original certificate of title (when
received) and otherwise such documents, if any, that NFC keeps on file in
accordance with its customary procedures indicating that the Financed Vehicle is
owned by the Obligor and subject to the interest of NFC as first lienholder or
secured party; and

         (e)    any and all other documents that NFC keeps on file in accordance
with its customary procedures relating to the individual Receivable, Obligor or
Financed Vehicle.

Pursuant to Sections 2.01(f) and 2.02(a)(vi), the rights of the Seller under the
Custodian Agreement are being assigned to the Owner Trustee.

     SECTION 2.4. Acceptance by Owner Trustee; Limitation on Transfer of
                  ------------------------------------------------------
International Purchase Obligations. The Owner Trustee does hereby accept all
----------------------------------
consideration conveyed by the Seller pursuant to Sections 2.01 and 2.02, and
declares that the Owner Trustee shall hold such consideration upon the trust set
forth in the Trust Agreement for the benefit of Certificateholders, subject to
the terms and conditions of the Trust Agreement, the Indenture and this
Agreement; provided, however, that the Owner Trustee acknowledges and agrees
           --------  -------
that (a) the rights pursuant to the International Purchase Obligations are
personal to NFC, and only the proceeds of such rights are being assigned to the
Owner Trustee pursuant to the terms hereof, (b) the Owner Trustee is not or is
not intended to be a third-party beneficiary of such rights, and (c) accordingly
such rights are not exercisable by, enforceable by or for the benefit of, or
preserved for the benefit of, the Owner Trustee. The Owner Trustee hereby agrees
and accepts the appointment and authorization of NFC as Servicer under Section
3.01. The parties agree that this Agreement (including any Subsequent Transfer
PSA Assignments), the Indenture and the Trust Agreement constitute the Further
Transfer and Servicing Agreements for purposes of the Purchase Agreement.

     SECTION 2.5. Representations and Warranties as to the Receivables.
                  ----------------------------------------------------
Pursuant to Sections 2.01(f) and 2.02(a)(vi), the Seller assigns to the Owner
Trustee all of its right, title and interest in, to and under the Purchase
Agreement. Such assigned right, title and interest includes the representations
and warranties of NFC made to the Seller pursuant to Section 3.01 of the
Purchase Agreement. The Seller hereby represents and warrants to the Owner
Trustee that the Seller has taken no action which would cause such
representations and warranties to be false in any material respect as of the
Closing Date, in the case of the Initial Receivables, and as of the related
Subsequent Transfer Date, in the case of Subsequent Receivables. The Seller
further acknowledges that the Owner Trustee is relying on the representations
and warranties of the Seller under this Agreement and of NFC under the Purchase
Agreement in accepting the Receivables in trust and executing and delivering the
Securities. The foregoing representation and warranty speaks as of the Closing
Date, in the case of the Initial Receivables, and as of the related Subsequent
Transfer Date, in the case of Subsequent Receivables, but shall survive the
sale, transfer and assignment of such Receivables to the Owner Trustee and the
pledge thereof to the Indenture Trustee pursuant to the Indenture.

     SECTION 2.6. Repurchase of Receivables Upon Breach of Warranty. Upon
                  -------------------------------------------------
discovery by the Seller, the Servicer or either Trustee of a breach of any of
the representations and warranties in Section 3.01 of the Purchase Agreement
(and, with respect to subsection 3.01(j) of the Purchase Agreement, irrespective
of any limitation regarding knowledge of NFC) or in Section 2.05 or Section 6.01
of this Agreement that materially and adversely affects the interests of the
Financial Parties in any Receivable, the party discovering such breach shall
give prompt written notice thereof to the others. As of the second Accounting
Date following its discovery or its receipt of notice of breach (or, at the
Seller's election, the first Accounting Date following such discovery), unless
such breach shall have been cured in all material respects, in the event of a
breach of the representations and warranties made by the Seller in Section 2.05
or Section 6.01, the Seller shall repurchase such Receivable from the Owner
Trustee on the related Distribution Date. The Owner Trustee 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 2.06.

                                       7

<PAGE>

     The repurchase price to be paid by any Warranty Purchaser shall be an
amount equal to the Warranty Payment. It is understood and agreed that the
obligation of the Warranty Purchaser to repurchase any Receivable as to which a
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 Interested Party. The Servicer acknowledges its
obligations to repurchase Administrative Receivables from the Owner Trustee
pursuant to Section 3.08 hereof and to repurchase Warranty Receivables pursuant
to Section 5.04 of the Purchase Agreement.

                                   ARTICLE III
                   ADMINISTRATION AND SERVICING OF RECEIVABLES

     SECTION 3.1. Duties of the Servicer. The Servicer is hereby appointed and
                  ----------------------
authorized to act as agent for the Owner of the Receivables 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 Owner of any Receivables with respect to distributions,
generating federal income tax information and performing the other duties
specified herein. Subject to the provisions of Section 3.02, 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 Owner of the Receivables, pursuant to this
Section 3.01, to execute and deliver, on behalf of all Interested Parties, or
any of them, 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 Owner of such Receivable or, to the
extent necessary, in its own name, a legal proceeding to enforce a Liquidating
Receivable as contemplated by Section 3.04, to enforce all obligations of NFC
and NFRRC, in its capacity as the Seller or otherwise, under each of the
Purchase Agreement and the Further Transfer and Servicing Agreements 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 Owner of such Receivable 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 Owner of a Receivable 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. Any Owner of Receivables, upon the written
request of the Servicer, shall furnish

                                       8

<PAGE>

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 other Further Transfer and Servicing Agreements. Except to the
extent required by the preceding two sentences, the authority and rights granted
to the Servicer in this Section 3.01 shall be nonexclusive and shall not be
construed to be in derogation of the retention by the Owner of a Receivable of
equivalent authority and rights.

     SECTION 3.2. 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 subsection 3.07(c),
the Servicer is hereby authorized to grant extensions, rebates or adjustments on
a Receivable without the prior consent of the Owner of such Receivable and to
rewrite, in its ordinary course of business, a Receivable to reflect the Full
Prepayment of a Receivable with respect to any Financed Vehicle without the
prior consent of the Owner of such Receivable. 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 such Receivable.

     SECTION 3.3. [Reserved.]


     SECTION 3.4. 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 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
shall 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 with respect to each Liquidating Receivable at
such time as the Receivable becomes a Liquidating Receivable in accordance with
subsection 4.06(b)(i).

     SECTION 3.5. 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,

                                       9

<PAGE>

unless the Servicer has in accordance with its customary 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 3.6. 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 Owner of each Receivable hereby authorizes the
Servicer to re-perfect such security interest as necessary because of the
relocation of a Financed Vehicle or for any other reason.

     SECTION 3.7. Covenants of the Servicer. The Servicer hereby makes the
                    -------------------------
following covenants on which the Owner Trustee, on behalf of the Trust, is
relying in acquiring the Receivables hereunder and issuing the Securities under
the other Further Transfer and Servicing Agreements. The Servicer covenants that
from and after the Closing Date:

     (a) Liens in Force. Except as contemplated in this Agreement, the Servicer
         --------------
shall not release in whole or in part any Financed Vehicle from the security
interest securing such related Receivable;

     (b) No Impairment. The Servicer shall do nothing to impair the rights of
         -------------
NFRRC or any Interested Party in and to such Receivables; and

     (c) No Modifications. The Servicer shall not amend or otherwise modify any
         ----------------
such Receivable such that the Starting Receivable Balance, the Annual Percentage
Rate or the total number of Scheduled Payments is altered or such that the final
scheduled payment on such Receivable will be due later than October 31, 2008.

     SECTION 3.8. Purchase of Receivables Upon Breach of Covenant. Upon
                    -----------------------------------------------
discovery by any of the Seller, the Servicer or any party under the Further
Transfer and Servicing Agreements of a breach of any of the covenants set forth
in Sections 3.06 and 3.07, the party discovering such breach shall give prompt
written notice thereof to the others. 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 Owner
thereof any Receivable materially and adversely affected by such breach as
determined by such Owner and, on the related Distribution 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 the Seller or any Interested Party. Neither the Owner Trustee nor
the Indenture Trustee shall have any affirmative duty to conduct any
investigation as to the occurrence of any event requiring the repurchase of any
Receivable pursuant to this Section 3.08.

                                       10

<PAGE>

     SECTION 3.9.  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 in respect of the
Receivables as provided herein. Subject to any limitations 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 Owner Trustee, any trustees and independent accountants,
taxes imposed on the Servicer, expenses incurred in connection with
distributions and reports to Financial Parties and all other fees and expenses
not expressly stated under this Agreement to be for the account of the Financial
Parties, but excluding federal, state and local income and franchise taxes, if
any, of the Owner Trustee or any Securityholder).

     SECTION 3.10. Servicer's Certificate. Not later than 10:00 a.m. (Chicago,
                   ----------------------
Illinois time) on each Determination Date, the Servicer shall deliver to each
Trustee and the Rating Agencies a Servicer's Certificate with respect to the
immediately preceding Monthly Period executed by the President or any Vice
President of the Servicer containing all information necessary to each such
party for making the calculations, withdrawals, deposits, transfers and
distributions required by Section 4.06, and all information required to be
provided to the Financial Parties under subsection 4.09(a). Receivables to be
purchased by the Servicer under Section 3.08 hereof or Section 5.04 of the
Purchase Agreement as of the last day of any Monthly Period shall be identified
by Receivable number (as set forth in the Schedule of Receivables). With respect
                                          -----------------------
to any Receivables for which the Seller is the Owner, the Servicer shall deliver
to the Seller such accountings relating to such Receivables and the actions of
the Servicer with respect thereto as the Seller may reasonably request.

     SECTION 3.11. Application of Collections. For the purposes of this
                   --------------------------
Agreement, as of each Accounting Date, all collections for the related Monthly
Period with respect to each Receivable shall be applied by the Servicer as
follows:

     (a) All payments by or on behalf of the Obligor (excluding Supplemental
Servicing Fees and Investment Earnings) shall be applied (i) first to reduce
                                                             -----
Outstanding Monthly Advances, if any, with respect to such Receivable, as
described in Section 5.06, (ii) second, to the Scheduled Payment for such
                                ------
Monthly Period with respect to such Receivable, and (iii) third, the remainder
                                                          -----
shall constitute, with respect to such Receivable, a Full Prepayment or Partial
Prepayment; and

     (b) A Partial Prepayment made on a Receivable is applied to reduce the
final Scheduled Payment and will thereafter, to the extent the Partial
Prepayment exceeds the final Scheduled Payment, reduce Scheduled Payments in
reverse chronological order beginning with the penultimate Scheduled Payment.
The Rebate related to such Partial Prepayment will reduce the final Scheduled
Payment and will thereafter, to the extent the Rebate exceeds the final

reasonable access to the documentation regarding the Receivables to a
Securityholder in cases where such Securityholder is required by applicable
statutes or regulations to review such documentation. In each case, such access
shall be afforded without charge but only upon reasonable request and during
normal business hours at offices of the Servicer designated by the Servicer.
Nothing in this Section 4.03 shall derogate from the obligation of the Servicer
to observe any applicable law prohibiting disclosure of information regarding
Obligors, and the failure of the Servicer to provide access as provided in this
Section 4.03 as a result of such obligation shall not constitute a breach of
this Section 4.03.

     SECTION 4.4. Amendments to Schedule of Receivables. On or before each
                  -------------------------------------
Subsequent Transfer Date occurring during the Funding Period, the Seller will
deliver to each Trustee a schedule of the Subsequent Receivables being
transferred to the Owner Trustee (and such schedule shall be deemed to
supplement the Schedule of Receivables). If the Servicer, during a Monthly
Period, assigns to a Receivable an account number that differs from the account
number previously identifying such Receivable on the Schedule of Receivables,
                                                     -----------------------
the Servicer shall deliver to the Seller and each Trustee on or before the

                  -----------------------------------------------------
Receivables. Upon receipt of the Administrative Purchase Payment or the Warranty
-----------
Payment with respect to an Administrative Receivable or a Warranty Receivable,
respectively, each Trustee shall assign, without recourse, representation or
warranty, to the Servicer or the Warranty Purchaser, as applicable, all of such
Trustee's right, title and interest in, to and under (a) such Administrative
Receivable or Warranty Receivable and all monies due thereon, (b) the security

relating thereto and (g) the rights of such Trustee 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 either Trustee or the Financial
Parties with respect thereto. If in any Proceeding it is held that the Servicer
may not enforce a Receivable on the ground that it is not a real party in
interest or a holder entitled to enforce the Receivable, the applicable Trustee
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 Financial Parties.

Account") to include the money and other property deposited and held therein
pursuant to this Section 4.07(a), Section 4.07(c), Section 4.06(c) and Section

Initial Deposit into the Reserve Account. The Reserve Account shall be the
property of the Owner Trustee, on behalf of the Trust, subject to the rights of
the Indenture Trustee in the Reserve Account Property.

     (b) If the amount on deposit in the Reserve Account on any Distribution
Date (after giving effect to all deposits therein or withdrawals therefrom on
such Distribution Date) exceeds the Specified Reserve Account Balance for such
Distribution Date, the Servicer shall instruct the Indenture Trustee to deposit
into the Certificate Distribution Account an amount equal to any such excess for
distribution to the Certificateholders or upon the order of the
Certificateholders in an account designated in writing by the Certificateholders
to the Servicer.

     (c) If the Servicer, pursuant to Section 5.06, determines on any
Determination Date that it is required to make a Monthly Advance and does not do
so from its own funds, the Servicer shall instruct the Indenture Trustee to
withdraw funds from the Reserve Account and deposit them in the Collection
Account to cover any shortfall. Such payment shall be deemed to have been made
by the Servicer pursuant to Section 5.06 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.

a basis other than a daily basis, the Servicer, the Seller, and each Trustee may
make any remittances pursuant to this Article IV net of amounts to be
distributed by the applicable recipient to such remitting party. Nonetheless,
each such party shall account for all of the above described remittances and
distributions as if the amounts were deposited and/or transferred separately.

     SECTION 4.9. Statements to Financial Parties.
                  -------------------------------

         (a)  (i)   The Servicer, for the benefit of the Financial Parties,
shall establish and maintain in the name of the Indenture Trustee an Eligible
Deposit Account known as the Navistar Financial 2001-B Owner Trust Collection
Account (the "Collection Account"), bearing an additional designation clearly
indicating that the funds deposited therein are held for the benefit of the
Financial Parties.

              (ii)  The Servicer, for the benefit of the Noteholders, shall

Account (the "Note Distribution Account"), bearing an additional designation
clearly indicating that the funds deposited therein are held for the benefit of

              (iii) Pursuant to the Trust Agreement, the Servicer, for the

         (b)  (i)   Each of the Designated Accounts shall be initially

Indenture Trustee so long as (A) the short-term unsecured debt obligations of
the Indenture Trustee have the Required Deposit Rating or (B) each of the
Designated Accounts are maintained in the corporate trust department of the
Indenture Trustee. All amounts held in such accounts (including amounts, if any,

invested in investments which have a rating from S&P of "A-1" rather than
"A-1+," if such investments otherwise constitute Eligible Investments. Such
written direction shall constitute certification by the Servicer that any such
investment is authorized by this Section 5.01. Funds deposited in the Reserve
Account, the Negative Carry Account and the Pre-Funding Account shall be
invested in Eligible Investments which mature prior to the next Distribution

Agency Condition is satisfied with respect thereto. Investments in Eligible
Investments shall be made in the name of the Indenture Trustee or its nominee,
and such investments shall not be sold or disposed of prior to their maturity.
Should the short-term unsecured debt obligations of the Indenture Trustee (or
any other bank or trust company with which the Designated Accounts are
maintained) no longer have the Required Deposit Rating, then the Servicer shall
within 10 Business Days (or such longer period, not to exceed 30 calendar days,
upon satisfaction of the Rating Agency Condition with respect thereto), with the
Indenture Trustee's assistance as necessary, cause the Designated Accounts (A)
to be moved to a bank or trust company, the short-term unsecured debt
obligations of which shall have the Required Deposit Rating, or (B) to be moved
to the corporate trust department of the Indenture Trustee. Except with respect
to Investment Earnings on amounts on deposit in the Pre-Funding Account,
Investment Earnings on funds deposited in the Designated Accounts shall be
deposited into the Certificate Distribution Account for distribution to the
Certificateholders, except when the Indenture Trustee is acting as successor
Servicer in which case such Investment Earnings shall be payable to the
Indenture Trustee as successor Servicer. The Indenture Trustee or the other
Person holding the Designated Accounts as provided in this Section 5.01(b)(i)
shall be the "Securities Intermediary." If the Securities Intermediary shall be
a Person other than the Indenture Trustee, the Servicer shall obtain the express
agreement of such Person to the obligations of the Securities Intermediary set
forth in this Section 5.01.

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

                      (A)   The Designated Accounts are accounts to which
              Financial Assets will be credited.

                      (B)   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
              Owner Trustee, the Servicer or the Seller, payable to the order of
              the Owner Trustee, the Servicer or the Seller or specially
              indorsed to the Owner Trustee, the Servicer or the Seller except
              to the extent the foregoing have been specially indorsed to the
              Securities Intermediary or in blank.

                      (C)   All property delivered to the Securities
              Intermediary pursuant to this Agreement will be promptly credited
              to the appropriate Designated Account.

                      (D)   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.

                      (E)   If at any time the Securities Intermediary shall
              receive any order from the Indenture Trustee 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 Owner Trustee,
              the Servicer, the Seller or any other Person.

                      (F)   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.

                      (G)   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 Owner Trustee, the Seller, the Servicer, the
              Indenture Trustee or the Swap Counterparty purporting to limit or
              condition the obligation of the Securities Intermediary to comply
              with entitlement orders as set forth in Section 5.01(b)(ii)(E)
              hereof.

                      (H)   Except for the claims and interest of the Indenture
              Trustee and of the Owner Trustee 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 Indenture Trustee, the
              Servicer, the Swap Counterparty and the Owner Trustee thereof.

                      (I)   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 Indenture
              Trustee at the addresses set forth in Appendix B to this
              Agreement.

              (iii)    The Servicer shall have the power, revocable by the
Indenture Trustee (or by the Owner Trustee with the consent of the Indenture
Trustee) to instruct the Indenture Trustee to

                                       21

<PAGE>

make withdrawals and payments from the Designated Accounts for the purpose of
permitting the Servicer or the Owner Trustee to carry out its respective duties
hereunder or permitting the Indenture Trustee to carry out its duties under the
Indenture.

              (iv)  The Indenture Trustee 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 (except Investment Earnings). Except as
otherwise provided herein or in the Indenture, the Designated Accounts shall be
under the sole dominion and control of the Indenture Trustee for the benefit of
the Financial Parties.

              (v)   The Servicer shall not direct the Indenture Trustee 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 Indenture Trustee to make any such
investment or sale, if requested by the Indenture Trustee, the Servicer shall
deliver to the Indenture Trustee an Opinion of Counsel, acceptable to the
Indenture Trustee, to such effect.

         (c)  Pursuant to the Trust Agreement, the Owner Trustee shall possess
all right, title and interest in and to all funds on deposit from time to time
in the Certificate Distribution Account and in all proceeds thereof. Except as
otherwise provided herein or in the Trust 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.

         (d)  The Indenture Trustee, the Owner Trustee, the Securities
Intermediary and each other Eligible Deposit Institution with whom a Designated
Account or the Certificate Distribution Account is maintained waives any right
of set-off, counterclaim, security interest or bankers' lien to which it might
otherwise be entitled.

         SECTION 5.2.   Pre-Funding Account. (a) On the Closing Date, the Seller
                        -------------------
shall deposit in the Pre-Funding Account $207,670,906.02 from the net proceeds
of the sale of the Notes. On each Subsequent Transfer Date, the Servicer shall
instruct the Indenture Trustee to withdraw from the Pre-Funding Account an
amount equal to (i) the aggregate Starting Receivable Balance of the Subsequent
Receivables transferred to the Owner Trustee on such Subsequent Transfer Date
less the Reserve Account Subsequent Transfer Deposit with respect to such
Subsequent Transfer Date and distribute such amount to or upon the order of the
Seller upon satisfaction of the conditions set forth in Section 2.02(b) with
respect to such transfer, and (ii) the Reserve Account Subsequent Transfer
Deposit with respect to such Subsequent Transfer Date and, on behalf of the
Seller, deposit such amount in the Reserve Account.

                                       22

<PAGE>

         (b)   If the Pre-Funded Amount has not been reduced to zero on or prior
to the Distribution Date on which the Funding Period ends (or, if the Funding
Period does not end on a Distribution Date, on the first Distribution Date
following the end of the Funding Period), the Servicer shall instruct the
Indenture Trustee to transfer from the Pre-Funding Account on such Distribution
Date any amount then remaining in the Pre-Funding Account to the Note
Distribution Account and, if such amount is greater than $100,000, the Seller,
on behalf of the Owner Trustee, will deposit into the Note Distribution Account
an amount equal to the aggregate of Noteholders' Prepayment Premiums for all
classes of Notes; provided, however, that the Owner Trustee's obligation to pay
                  -----------------
the Noteholders' Prepayment Premiums shall be limited to funds which are
received by the Owner Trustee from the Seller pursuant to Section 2.02(c) hereof
as liquidated damages for the failure to deliver the Subsequent Receivables, and
no other assets of the Owner Trustee will be available for making such payments.
If the amount of funds available for payment of the Noteholders' Prepayment
Premiums is less than the sum of the Noteholders' Prepayment Premium for each
class of Notes, then the available funds will be allocated among each class of
Notes in accordance with the Pre-Funded Percentage for such class of Notes.

         SECTION 5.3.   Negative Carry Account. (a) On the Closing Date, the
                        ----------------------
Seller shall deposit in the Negative Carry Account $1,523,000.41 (the "Negative
Carry Account Initial Deposit") from the net proceeds of the sale of the Notes.
On or before the Transfer Date preceding each Distribution Date occurring on or
prior to the first Distribution Date that occurs on or after the end of the
Funding Period, the Servicer will instruct the Indenture Trustee to withdraw
from the Negative Carry Account and deposit into the Collection Account an
amount equal to the Negative Carry Amount for such Distribution Date.

         (b)   On each Distribution Date during the Funding Period, the Servicer
will instruct the Indenture Trustee to withdraw from the Negative Carry Account
an amount equal to the excess, if any, of the amount on deposit in the Negative
Carry Account over the Required Negative Carry Account Balance and deposit it
(i) in the Certificate Distribution Account for distribution to the
Certificateholders or (ii) upon the order of the Certificateholders in an
account designated in writing by the Certificateholders to the Servicer, and on
the Distribution Date on or immediately following the last day of the Funding
Period, the Servicer will instruct the Indenture Trustee to withdraw from the
Negative Carry Account the amount remaining on deposit in the Negative Carry
Account and deposit it in the Certificate Distribution Account for distribution
to the Certificateholders or upon the order of the Certificateholders in an
account designated in writing by the Certificateholders to the Servicer.

         SECTION 5.4.   Collections. The Servicer shall remit to the Collection
                        -----------
Account all payments by or on behalf of the Obligors on the Receivables, all
Insurance Proceeds, all Liquidation Proceeds, proceeds from any Dealer
Liability, proceeds from any International Purchase Obligations and proceeds
from any Guaranties within two Business Days after receipt thereof.
Notwithstanding the foregoing, the Servicer shall not be required to remit such
collections within such two Business Days but may remit collections received
during a Monthly Period to the Collection Account in immediately available funds
on the Business Day immediately preceding the related Distribution

                                       23

<PAGE>

Date but only for so long as (i) NFC is the Servicer, (ii) (x) the Servicer
satisfies the requirements for monthly remittances established by the Rating
Agencies initially rating the Securities, and upon the satisfaction of such
requirements, the Rating Agencies which initially rated the Securities reaffirm
the rating of the Securities at the level at which they would be rated if
collections were remitted within two Business Days or (y) the short-term
unsecured debt obligations of NFC are rated at least A-1+ by S&P and P-1 by
Moody's Investors Service, Inc., and (iii) a Servicer Default shall not have
occurred and be continuing. The Indenture Trustee shall not be deemed to have
knowledge of any event or circumstance under clause (iii) of the immediately
preceding sentence that would require remittance within two Business Days by the
Servicer to the Collection Account unless the Indenture Trustee has received
notice of such event or circumstance from the Seller or the Servicer in an
Officer's Certificate or from Noteholders whose Notes evidence not less than 25%
of the Outstanding Amount of the Voting Notes as of the close of the preceding
Distribution Date or unless a Responsible Officer in the Corporate Trust Office
with knowledge hereof and familiarity herewith has actual knowledge of such
event or circumstance. For purposes of this Article V the phrase "payments by or
on behalf of Obligors" shall mean payments made by Persons other than the
Servicer.

         SECTION 5.5.   Investment Earnings and Supplemental Servicing Fees. The
                        ---------------------------------------------------
Servicer shall be entitled to receive all Supplemental Servicing Fees, and,
except as otherwise provided in Section 5.01(b)(i) hereof, the
Certificateholders (via the Certificate Distribution Account or such other
account as shall be designated in writing by the Certificateholders to the
Servicer) shall be entitled to receive all Investment Earnings (other than
Investment Earnings from amounts on deposit in the Pre-Funding Account), when
and as paid without any obligation to (a) either Trustee, (b) with respect to
the Supplemental Servicing Fees, the Certificateholders or (c) with respect to
the Investment Earnings, the Servicer, in respect thereof. The Servicer will not
have any obligation to deposit any such amount in any account established
hereunder. To the extent that any such amount shall be held in any account
(other than, with respect to amounts to be distributed to the
Certificateholders, the Certificate Distribution Account) held by either
Trustee, or otherwise established hereunder, such amount will be withdrawn
therefrom and paid to the Servicer or deposited in the Certificate Distribution
Account for distribution to the Certificateholders, as applicable, upon
presentation of a certificate signed by a Responsible Officer of such Person
setting forth, in reasonable detail, the amount of such Supplemental Servicing
Fees or such Investment Earnings, respectively.

         SECTION 5.6.   Monthly Advances. Subject to the following sentence, as
                        ----------------
of each Accounting 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 subsection 3.11(a)(i) 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 4.07(c), 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 payments with respect to such
Receivable, the Servicer shall be reimbursed from any collections made on other
Receivables.

         SECTION 5.7.   Additional Deposits. The Servicer shall deposit in the
                        -------------------
Collection Account the aggregate Monthly Advances pursuant to Section 5.06. The
Servicer and the Seller 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 Business Day before the Distribution Date related to such Monthly
Period.

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

         (a)    The Servicer shall be liable in accordance with this Agreement
only to the extent of the obligations in this Agreement specifically undertaken
by the Servicer. Such obligations shall include the following:

                (i)   The Servicer shall defend, indemnify and hold harmless the
         Indenture Trustee, the Owner Trustee, the Owner Trust Estate and the

         transactions contemplated in this Agreement, including any sales, gross
         receipts, general corporation, Illinois corporate income, tangible
         personal property, privilege or license taxes (but not including any

         or liability arose out of, or was imposed upon such Trustee or the
         Financial Parties through the negligence, willful misfeasance or bad
         faith of the Servicer in the performance of its duties under this
         Agreement and any other Transfer and Servicing Agreements or by reason
         of reckless disregard of its obligations and duties under any of the

         Estate, and the Trust Agreement (in the case of the Owner Trustee),
         including the administration of the Owner Trust Estate, except in each
         case to the extent that such cost, expense, loss, claim, damage or
         liability: (A) is due to the willful misfeasance, bad faith or
         negligence (except for errors in judgment) of the Person seeking to be
         indemnified, (B) to the extent otherwise payable to the Indenture
         Trustee, arises from the Indenture Trustee's breach of any of its
         representations or warranties in Section 6.13 of the Indenture or (C)
         to the extent otherwise payable to the Owner Trustee, arises from the

termination of this Agreement and shall include reasonable fees and expenses of
counsel and expenses of litigation. If the Servicer has made any indemnity
payments pursuant to this Section 7.01 and the recipient thereafter collects any
of such amounts from others, the recipient shall promptly repay such amounts
collected to the Servicer, without interest.

         SECTION 7.2.    Merger or Consolidation of, or Assumption of the
                         ------------------------------------------------

owned directly or indirectly by NIC and which is otherwise servicing the
Seller's receivables, which corporation in any of the foregoing cases executes
an agreement of assumption to perform every obligation of the Servicer under
this Agreement shall be the successor to the Servicer under this Agreement
without the execution or filing of any paper or any further act on the part of
any of the parties to this Agreement, notwithstanding anything in this Agreement
to the contrary. The Servicer shall provide notice of any merger, consolidation
or succession pursuant to this Section 7.02 to the Rating Agencies.

         SECTION 7.3.    Limitation on Liability of Servicer and Others.
                         ----------------------------------------------

         (a)   Neither the Servicer nor any of the directors or officers or
employees or agents of the Servicer shall be under any liability to the Owner
Trustee or the Financial Parties, except as specifically provided in this
Agreement, for any action taken or for refraining from the taking of any action
pursuant to the Further Transfer and Servicing Agreements or for errors in
judgment; provided, however, that this provision shall not protect the Servicer
          --------  -------
or any such Person against any liability that would otherwise be imposed by
reason of willful misfeasance, bad faith or negligence (except errors in
judgment) in the performance of duties or by reason of reckless disregard of
obligations and duties under the Further Transfer and Servicing Agreements. The
Servicer and any director, officer or employee or agent of the Servicer may rely
in good faith on the advice of counsel or on any document of any kind prima
facie properly executed and submitted by any Person respecting any matters
arising under this Agreement.

         (c)   Except as provided in this Agreement, the Servicer shall not be
under any obligation to appear in, prosecute or defend any legal action that is
not incidental to its duties to service the Receivables in accordance with this
Agreement and that in its opinion may involve it in any expense or liability;
provided, however, that the Servicer may undertake any reasonable action that it
--------  -------
may deem necessary or desirable in respect of this Agreement and the rights and
duties of the parties to this Agreement and the interests of the Financial
Parties under this Agreement and the Noteholders and (to the extent expressly
provided therein) the Certificateholders under the Indenture and the interests
of the Certificateholders under the Trust Agreement. In such event, the legal
expenses and costs for such action and any liability resulting therefrom shall
be expenses, costs and liabilities of the Owner Trustee payable from the Owner
Trust Estate and the Servicer shall be entitled to be reimbursed therefor.

         (d)   The Applicable Trustee shall distribute out of the Collection
Account on a Distribution Date any amounts permitted for reimbursement pursuant
to subsection 7.03(c) which have not been previously reimbursed after any
deposit to the Reserve Account pursuant to Section 4.06(c)(v) and before any
distribution to the Certificate Distribution Account pursuant to Section
4.07(b); provided, however, that the Applicable Trustee shall not distribute
         --------  -------
such amounts if the amount on deposit in the Reserve Account (after giving
effect to all deposits and withdrawals pursuant to Sections 4.06(b) and (c) and
Section 4.07(c), on such Distribution Date) is greater than zero but less than
the Specified Reserve Account Balance for such Distribution Date.

         SECTION 7.4.    Delegation of Duties. So long as NFC acts as Servicer,
                        --------------------
the Servicer may, at any time without notice or consent, delegate any duties

perform specific duties as Servicer through sub-contractors who are in the

provided, however, that no such delegation shall relieve the Servicer of its
-------- ------- responsibility with respect to such duties.

         SECTION 7.5.    Servicer Not to Resign. Subject to the provisions of
                         ----------------------
Section 8.02, 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

each Trustee. No such resignation shall become effective until the Indenture
Trustee or a successor Servicer shall have assumed the responsibilities and
obligations of the Servicer in accordance with Section 8.02.

deposit in the Certificate Distribution Account any required payment or to
direct the Indenture Trustee to make any required distributions therefrom, which
failure continues unremedied for a period of five Business Days after written
notice is received by the Servicer from the Applicable Trustee or after
discovery of such failure by an officer of the Servicer;

         (b)    failure on the part of the Seller or the Servicer to duly
observe or perform in any material respect any other covenants or agreements of
the Seller or the Servicer set forth in the Purchase Agreement, this Agreement
or any of the other Further Transfer and Servicing Agreements which failure (i)
materially and adversely affects the rights of Financial Parties, and (ii)

to the Seller or the Servicer, as applicable, by either Trustee, or to the
Seller or the Servicer, as applicable, and to either Trustee by Noteholders
whose Notes evidence not less than 25% of the Outstanding Amount of the Voting
Notes as of the close of the preceding Distribution Date (or, if the Notes have
been paid in full and the Indenture has been discharged in accordance with its
terms, by Certificateholders whose Certificates evidence not less than 25% of
the ownership interest in the Trust as of the close of the preceding
Distribution Date);

         (c)    the entry of a decree or order by a court or agency or
supervisory authority having jurisdiction in the premises for the appointment of
a conservator, receiver or liquidator for the Seller or the Servicer, in any
insolvency, readjustment of debt, marshaling of assets and liabilities or
similar proceedings, or for the winding up or liquidation of their respective
affairs, and the continuance of any such decree or order unstayed and in effect

respective property; or the Seller or the Servicer shall admit in writing its
inability to pay its debts generally as they become due, file a petition to take
advantage of any applicable insolvency or reorganization statute, make an
assignment for the benefit of its creditors or voluntarily suspend payment of
its obligations.

         SECTION 8.2.    Consequences of a Servicer Default. If a Servicer
                         ----------------------------------
Default shall occur and be continuing, either the Indenture Trustee or the
Noteholders whose Notes evidence not less than a majority of the Outstanding
Amount of the Voting Notes as of the close of the preceding Distribution Date
(or, if the Notes have been paid in full and the Indenture has been discharged
in accordance with its terms, by the Owner Trustee or the Holders of
Certificates evidencing not less than a majority of the ownership interest in
the Trust as of the close of the preceding Distribution Date) by notice then
given in writing to the Servicer and the Owner Trustee (and to the Indenture
Trustee if given by the Financial Parties) 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, including the termination of all sub-

                                       32

servicing agreements, without cost. 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 Securities or the Receivables or
otherwise, shall pass to and be vested in the Indenture Trustee pursuant to and
under this Section 8.02. The Indenture Trustee is hereby authorized and
empowered to execute and deliver, on behalf of the 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 Servicer
agrees to cooperate with either Trustee in effecting the termination of the
responsibilities and rights of the Servicer under this Agreement, including the
transfer to either Trustee for administration by it of all cash amounts that
shall at the time be held by the Servicer for deposit, or that shall have been
deposited by the Servicer in the Collection Account, the Negative Carry Account,
the Pre-Funding Account, the Reserve Account, the Note Distribution Account or
the Certificate Distribution Account or thereafter received with respect to the
Receivables that shall at that time be held by the Servicer. In addition to any
other amounts that are then payable to the Servicer under this Agreement, the
Servicer shall be entitled to receive from the successor Servicer reimbursements
for any Outstanding Monthly Advances made during the period prior to the notice
pursuant to this Section 8.02 which terminates the obligation and rights of the
Servicer under this Agreement.

         SECTION 8.3.    Indenture Trustee to Act; Appointment of Successor.
                         --------------------------------------------------
On and after the time the Servicer receives a notice of termination pursuant to
Section 8.02, the Indenture Trustee 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, and shall be subject
to all the responsibilities, restrictions, duties and liabilities relating
thereto placed on the Servicer by the terms and provisions of 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 Indenture Trustee shall
be entitled to such compensation (whether payable out of the Collection Account
or otherwise) as the 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 and shall be entitled to
Investment Earnings as set forth in Section 5.01(b)(i) hereof. Notwithstanding
the above, the Indenture Trustee may, if it shall be unwilling so to act, or
shall, if it is legally unable so to act, appoint, or petition a court of
competent jurisdiction to appoint, a successor (i) having a net worth of not
less than $100,000,000 and (ii) whose regular business includes the servicing of
medium and heavy duty truck, bus and trailer receivables, as the successor to
the Servicer under this Agreement in the assumption of all or any part of the
responsibilities, duties or liabilities of the Servicer under this Agreement. In
connection with such appointment and assumption, the Indenture Trustee may make
such arrangements for the compensation of such successor out of payments on
Receivables as it and such successor shall agree; provided, however, that no
                                                  --------  -------
such compensation shall be in excess of that permitted the Servicer under this
Agreement. The Indenture Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession.

         SECTION 8.4.    Notification to Financial Parties. Upon any
                         ---------------------------------
termination of, or appointment of a successor to, the Servicer pursuant to this
Article VIII, the Indenture Trustee shall give prompt written notice thereof to
the Noteholders and the Rating Agencies and the Owner Trustee shall give prompt
written notice thereof to the Certificateholders.

         SECTION 8.5.    Waiver of Past Defaults. Noteholders whose Notes
                         -----------------------
evidence not less than a majority of the Outstanding Amount of the Voting Notes
as of the close of the preceding Distribution Date (or, if all of the Notes have
been paid in full and the Indenture has been discharged in accordance with its
terms, Holders of Certificates evidencing not less than a majority of the
ownership interest in the Trust as of the close of the preceding Distribution
Date) may, on behalf of all Financial Parties, waive any default by the Servicer
in the performance of its obligations hereunder and its consequences, except a
default in making any required deposits to or payments from any of the accounts
in accordance with this Agreement. Upon any such waiver of a past default, such
default shall cease to exist, and any Servicer Default arising therefrom shall
be deemed to have been remedied for every purpose of this Agreement. No such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

         SECTION 8.6.    Repayment of Advances. If the identity of the
                         ---------------------
Servicer shall change, the predecessor Servicer shall be entitled to receive, to
the extent of available funds, reimbursement for Outstanding Monthly Advances
pursuant to Section 5.06 in the manner specified in Section 4.06, with respect
to all Monthly Advances made by such predecessor Servicer.

of any Monthly Period as of which (i) the Aggregate Receivables Balance is 10%
or less of the Aggregate Starting Receivables Balance and (ii) the Class A-1
Notes, the Class A-2 Notes and the Class A-3 Notes have been paid in full, the
Servicer shall have the option to purchase the assets of the Owner Trust Estate
other than the Designated Accounts and the Certificate Distribution Account. If
the Servicer's long term unsecured debt rating from Moody's Investors Service,
Inc. is equal to or higher than Baa3 at the time that it seeks to exercise such
option, then to exercise such option, the Servicer shall deposit in the
Collection Account an amount equal to the aggregate Administrative Purchase
Payments for the Receivables (including Liquidating Receivables), plus the
appraised value of any such other property contained in the Owner Trust Estate
(less the Liquidation Expenses to be incurred in connection with the recovery
thereof), such value to be determined by an appraiser mutually agreed upon by
the Servicer and each Trustee. If the Servicer's long term unsecured debt rating
from Moody's Investors Service, Inc. is less than Baa3 at the time that it seeks
to exercise such option, then to exercise such option, the Servicer shall
deposit in the Collection Account an amount equal to the appraised value of the
Receivables (including Liquidating Receivables), plus the appraised value of any
such other property contained in the Owner Trust Estate (less the Liquidation
Expenses to be incurred in connection with the recovery thereof), such values to
be determined by an appraiser mutually agreed upon by the Servicer and each
Trustee; provided, that such amount (when added to any funds then on deposit in
the Designated Accounts) must be at least equal to the aggregate Redemption
Price of the outstanding Notes to be redeemed with such proceeds for the
Distribution Date related to the Monthly Period in which such option is
exercised. Thereupon, the Servicer shall succeed to all interests in and to the
Owner Trust Estate (other than the Designated Accounts and the Certificate
Distribution Account).

proceeds from such disposition after all payments and reserves therefrom have
been made or the amount specified in clause SECOND of Section 5.4(b) of the
Indenture (the "Event of Default Proceeds") in the Collection Account. On the
day preceding the Distribution Date on which the Event of Default Proceeds are
deposited in the Collection Account (or, if such proceeds are not so deposited
on the day preceding a Distribution Date, on the day preceding the Distribution
Date immediately following such deposit), the Servicer shall instruct the
Applicable Trustee to make the following deposits (after the application on the
day preceding such Distribution Date of the Available Amount and funds on
deposit in the Reserve Account pursuant to Sections 4.06 and 4.07) from the
Event of Default Proceeds and any funds remaining on deposit in the Reserve
Account (including the proceeds of any sale of investments therein as described
in the following sentence) in the following priority:

         payments due to the Swap Counterparty in respect of an Early
         Termination Date under the Interest Rate Swap);

         of the Aggregate Class A Noteholders' Interest Distributable Amount and

         Counterparty in connection with any Early Termination Date of the
         Interest Rate Swap, allocated between the Note Distribution Account and
         the Swap Counterparty in proportion to the amounts owing to the Swap
         Counterparty in connection with such Early Termination Date and in
         respect of the Aggregate Class A Noteholders' Interest Distributable
         Amount;

conclusive and binding on such Person and on all future holders of such Notes or
Certificates and of any Notes or Certificates issued upon the transfer thereof

collections of payments on Receivables or distributions that shall be required
to be made on any Security, the Interest Rate for any class of Notes or the
Specified Reserve Account Balance or (b) reduce the aforesaid percentage
required to consent to any such amendment, without the consent of the holders of
all Securities then outstanding or (ii) amend any provision of this Agreement
(including Section 10.06) which requires actions taken under such provision to
have the consent of Noteholders whose Notes evidence greater than a majority of
the Outstanding Amount of the Voting Notes as of the preceding Distribution Date
or of the Holders of Certificates evidencing greater than a majority of the

         (e)    It shall not be necessary for the consent of Financial Parties
pursuant to subsection 10.01(b) to approve the particular form of any proposed
amendment or consent, but it shall be sufficient if such consent shall approve
the substance thereof. The manner of obtaining such consents (and any other
consents of Financial Parties provided for in this Agreement) and of evidencing
the authorization of the execution thereof by Financial Parties shall be subject
to such reasonable requirements as either Trustee may prescribe, including the
establishment of record dates pursuant to paragraph number 3 of the Note
Depository Agreement.

         (f)    Prior to the execution of any amendment to this Agreement, each
Trustee shall be entitled to receive and rely upon the Opinion of Counsel
referred to in subsection 10.02(i) and an Opinion of Counsel stating that the
execution of such amendment is authorized or permitted by this Agreement and
that all conditions precedent to the execution and delivery of such amendment
have been satisfied. Each Trustee may, but shall not be obligated to, enter into
any such amendment which affects such Trustee's own rights, duties or immunities
under this Agreement or otherwise.

lender or other transferee, the Servicer shall give to such prospective
purchaser, lender or other transferee computer tapes, records or print-outs
(including any restored from back-up archives) that, if they refer in any manner
whatsoever to any Receivable, indicate clearly that such Receivable has been
sold and is owned by the Owner Trustee unless such Receivable has been paid in
full or repurchased by the Seller or purchased by the Servicer.

         (g)    The Servicer shall permit each Trustee and their respective
agents at any time to inspect, audit and make copies of and abstracts from the
Servicer's records regarding any Receivables then or previously included in the
Owner Trust Estate.

the Receivables, and reciting the details of such filings or referring to prior
Opinions of Counsel in which such details are given, or (b) stating that, in the
opinion of such counsel, no such action is necessary to preserve and protect
such interest.

                         PART II - RULES OF CONSTRUCTION

     (a) Accounting Terms. As used in this Appendix or the Basic Documents,
         ----------------
accounting terms which are not defined, and accounting terms partly defined,
herein or therein shall have the respective meanings given to them under
generally accepted accounting principles. To the extent that the definitions of
accounting terms in this Appendix or the Basic Documents are inconsistent with
the meanings of such terms under generally accepted accounting principles, the
definitions contained in this Appendix or the Basic Documents will control.

     (b) "Hereof," etc. The words "hereof," "herein" and "hereunder" and words
          ------------
of similar import when used in this Appendix or any Basic Document will refer to
this Appendix or such Basic Document as a whole and not to any particular
provision of this Appendix or such Basic Document; and Section, Schedule and
Exhibit references contained in this Appendix or any Basic Document are
references to Sections, Schedules and Exhibits in or to this Appendix or such
Basic Document unless otherwise specified. The word "or" is not exclusive.

     (c) Reference to Distribution Dates. With respect to any Distribution Date,
         -------------------------------
the "related Monthly Period," and the "related Record Date," will mean the
Monthly Period and Record Date, respectively, immediately preceding such
Distribution Date, and the relationships among Monthly Periods and Record Dates
will be correlative to the foregoing relationships.

     (d) Number and Gender. Each defined term used in this Appendix or the Basic
         -----------------
Documents has a comparable meaning when used in its plural or singular form.
Each gender-specific term used in this Appendix or the Basic Documents has a
comparable meaning whether used in a masculine, feminine or gender-neutral form.

     (e) Including. Whenever the term "including" (whether or not that term is
         ---------
followed by the phrase "but not limited to" or "without limitation" or words of
similar effect) is used in this Appendix or the Basic Documents in connection
with a listing of items within a particular classification, that listing will be
interpreted to be illustrative only and will not be interpreted as a limitation
on, or exclusive listing of, the items within that classification.
