                                POOLING AGREEMENT

     THIS POOLING AGREEMENT is made as of November 19, 2002 by and between
Navistar Financial Retail Receivables Corporation, a Delaware corporation
("NFRRC" and, in its capacity as the Seller hereunder, the "Seller") and
Navistar Financial 2002-B Owner Trust, a Delaware statutory trust (the
"Issuer").

     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 Issuer in exchange for the
Securities and the payment of funds withdrawn from the Pre-Funding Account
pursuant to the terms of this Agreement.

     WHEREAS, the Seller and the Issuer wish to set forth the terms pursuant to
which the Receivables are to be sold by the Seller to the Issuer.

     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

     SECTION 1.01 Definitions. Certain capitalized terms used in the above
recitals and in this Agreement are defined in and shall have the respective
meanings assigned them in Part I of Appendix A to this Agreement. All references
herein to "the Agreement" or "this Agreement" are to this Pooling Agreement as
it may be amended, supplemented (whether by Subsequent Transfer PSA Assignment
or otherwise) or modified from time to time, the exhibits hereto and the
capitalized terms used herein which are defined in such Appendix A, and all
references herein to Articles, Sections and subsections are to Articles,
Sections or subsections of this Agreement unless otherwise specified. The rules
of construction set forth in Part II of such Appendix A shall be applicable to
this Agreement.

                                   ARTICLE II
          CONVEYANCE OF RECEIVABLES; ORIGINAL ISSUANCE OF CERTIFICATES

     SECTION 2.01 Conveyance of Initial Receivables. In consideration of the
Issuer'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 the Issuer, without recourse (except as provided in Section 2.06),
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:

<PAGE>


          (a) the Retail Notes identified on the Schedule of Retail Notes to the
Initial PSA Assignment delivered to the Issuer and the Related Retail Note
Assets with respect to those Retail Notes;

          (b) the Series 2002-B Portfolio Interest, the Series 2002-B Portfolio
Certificate and the beneficial interest in the Series 2002-B Portfolio Assets,
including the Retail Leases identified on the Schedule of Retail Leases to the
Initial PSA Assignment delivered to the Issuer and the Related Titling Trust
Assets with respect to those Retail Leases;

          (c) the rights, but not the obligations, of NFC under the Lease
Purchase Agreement and the Initial LPA Assignment with respect to the Retail
Leases included in the Initial Receivables; and

          (d) the rights, but not the obligations, of the Seller under the
Purchase Agreement and the Initial PA Assignment pursuant to Section 2.01 of the
Purchase Agreement with respect to the Initial Receivables.

In addition, on the Closing Date the Seller shall deposit the Reserve Account
Initial Deposit into the Reserve Account, the Pre-Funding Account Initial
Deposit into the Pre-Funding Account and the Negative Carry Account Initial
Deposit into the Negative Carry Account. 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, the Series 2002-B Portfolio Interest and the
Series 2002-B Portfolio Certificate from the Seller to the Issuer 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 intends 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 Issuer 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 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 lease payments and 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 2.02 Conveyance of Subsequent Receivables. (a) Subject to
satisfaction of the conditions set forth in Section 2.02(b) below, in
consideration of the Issuer's delivery on the related Subsequent Transfer Date
to or upon the order of the Seller of the amount described in Section 8.11(a) of
the Indenture to be delivered to the Seller, the Seller does hereby agree to
sell, transfer, assign, set over and otherwise convey to the Issuer, without
recourse (except as provided in Section 2.06, 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 Retail Notes identified on the Schedule of Retail Notes
     to such Subsequent Transfer PSA Assignment delivered to the Issuer and the
     Related Retail Note Assets with respect to those Retail Notes;

               (ii) the beneficial interest in the Series 2002-B Portfolio
     Assets, including the Retail Leases identified on the Schedule of Retail
     Leases to such Subsequent Transfer PSA Assignment delivered to the Issuer
     and the Related Titling Trust Assets with respect to those Retail Leases;

               (iii) the rights, but not the obligations, of NFC under the Lease
     Purchase Agreement and the Subsequent LPA Assignment with respect to the
     Retail Leases included in those Subsequent Receivables; and

               (iv) the rights, but not the obligations, of the Seller under the
     Purchase Agreement and the Subsequent Transfer PA Assignment pursuant to
     Section 2.01 of the Purchase Agreement with respect to those Subsequent
     Receivables.

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 Issuer 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 intends 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 Issuer 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 lease
payments and principal and interest payments in respect of the Subsequent

                                      -3-

<PAGE>

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 Issuer 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 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 the Schedule of Retail Notes and the
     Schedule of Retail Leases included in such Subsequent Receivables (which
     schedules shall be deemed to supplement the existing Composite 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 8.10(a) of the Indenture;

               (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 Issuer 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 Issuer 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 7.25%, (B) the weighted average remaining maturity of the Receivables
     in the Trust shall not be greater than 53

                                      -4-

<PAGE>

     months, (C) the aggregate Receivable Balance of all Receivables owing from
     a single Obligor shall not be more than 2.00% of the aggregate Receivable
     Balance of all Receivables in the Trust, and (D) the Aggregate Starting
     Receivable Balance of all Retail Leases in the Trust shall not exceed
     10.00% of the Aggregate Starting Receivable Balance;

               (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)(iv), (a)(v), (s), (t), (w), and (x) of the Purchase
     Agreement;

               (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; and

               (xii) Each Retail Lease has been allocated to the Series 2002-B
     Portfolio Interest in accordance with the terms of the Titling Trust
     Documents.

          (c) The Seller covenants to transfer to the Issuer pursuant to Section
2.02(a) before the termination of the Funding Period, Subsequent Receivables
with an aggregate Starting Receivable Balance equal to the amount of the
Pre-Funding Account Initial Deposit. 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 Issuer 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 Issuer, the Owner Trustee, the Indenture Trustee and Financial
Parties with respect to a failure of the Seller to comply with this covenant.

     SECTION 2.03 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 Servicing Agreement with NFC, pursuant
to which the Seller shall revocably appoint NFC as the

                                      -5-

<PAGE>

Custodian, and NFC 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 Trust, 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 or Retail Lease 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) if such Receivable is a Retail Note, 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;

          (e) if such Receivable is a Retail Lease, the Certificate of Title and
such other documents that NFC is required to maintain pursuant to Section 3.6 of
the Titling Trust Servicing Agreement; and

          (f) 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.

     SECTION 2.04 Acceptance by Issuer; Limitation on Transfer of International
Purchase Obligations. The Issuer does hereby accept all consideration conveyed
by the Seller pursuant to Sections 2.01 and 2.02, and declares that the Issuer
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 Issuer acknowledges and agrees that (a) the rights pursuant to the
International Purchase Obligations are personal to NFC and only the proceeds of
such rights have been assigned to the Issuer hereunder and, with respect to the
Retail Notes and Related Retail Note Assets, by NFC to NFRRC under the Purchase
Agreement and from NFRRC to the Issuer hereunder and with respect to Retail
Leases and Related Titling Trust Assets, by Harco Leasing to NFC under the Lease
Purchase Agreement, from NFC to NFRRC under the Purchase Agreement and from
NFRRC to the Issuer hereunder, (b) neither the Issuer nor the Indenture Trustee
is or is 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 Issuer or the Indenture
Trustee. The Issuer hereby agrees and accepts the appointment and authorization
of NFC as Servicer pursuant to the Servicing Agreement. The parties agree that
this Agreement (including each PSA Assignment), the Servicing Agreement, the
Indenture and the Trust Agreement constitute the Further Transfer and Servicing
Agreements.

     SECTION 2.05 Representations and Warranties as to the Receivables. Pursuant
to Sections 2.01(d) and 2.02(a)(iv), the Seller assigns to the Issuer all of its
right, title and interest in, to and under the Purchase Agreement. Such assigned
right, title and interest includes the

                                      -6-

<PAGE>

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
Issuer 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 Issuer is relying on the representations and
warranties of the Seller under this Agreement and of NFC under the Purchase
Agreement in accepting the Receivables, the Series 2002-B Portfolio Interest and
the Series 2002-B Portfolio Certificate 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 the Receivables, the Series 2002-B
Portfolio Interest and the Series 2002-B Portfolio Certificate to the Issuer and
the pledge thereof to the Indenture Trustee pursuant to the Indenture.

     SECTION 2.06 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 Section 3.01(j) of the Purchase Agreement, irrespective of
any limitation regarding knowledge of NFC) or in Section 2.05 or Section 3.01 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 or
notice), 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 3.01, the Seller shall repurchase such Receivable
from the Issuer on the related Distribution Date. Neither the Owner Trustee nor
the Issuer 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 2.06.

          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.

                                  ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE SELLER

     SECTION 3.01 Representations and Warranties of the Seller. The Seller makes
the following representations and warranties as to itself on which the Issuer is
relying in acquiring the Receivables, the Series 2002-B Portfolio Interest and
the Series 2002-B Portfolio Certificate hereunder and issuing the Securities
under the other Further Transfer and Servicing Agreements. The following
representations and warranties speak as of the Closing Date in the case of the
Initial Receivables and as of the applicable Subsequent Transfer Date in the
case of the Subsequent Receivables, but in each case shall survive the sale,
transfer and assignment of

                                      -7-

<PAGE>

such Receivables to the Issuer and the pledge thereof to the Indenture Trustee
pursuant to the Indenture.

          (c) Power and Authority. The Seller has the power and authority to

                                   ARTICLE IV

of the Aggregate Starting Receivables Balance and (ii) the Class A-1 Notes, the
Class A-2 Notes, the Class A-3a Notes, and the Class A-3b Notes have been paid

Trust Estate other than the Designated Accounts and the Certificate Distribution

<PAGE>

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
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).

and any other assets remaining in the Owner Trust Estate shall be distributed to
the Certificate Distribution Account for distribution to the Certificateholders.

provision in this Agreement that may be defective or inconsistent with any other
provision in this Agreement or any other Basic Document, (iii) to add or
supplement any credit enhancement for the benefit of the Noteholders of any
class or the Certificateholders provided that if any such addition shall affect
any class of Noteholders or the Certificateholders differently than any other
class of Noteholders or the Certificateholders, respectively, then such addition
shall not, as evidenced by an Opinion of Counsel, adversely affect in any
material respect the interests of any class of Noteholders or the

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
or in exchange thereof or in lieu thereof whether or not notation of such
consent is made upon the Notes or Certificates) for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Agreement, or of modifying in any manner the rights of the Financial
Parties; provided, however, that no such amendment shall (i)(a) increase or
reduce in any manner the amount of, or accelerate or delay the timing of,
collections of payments on Receivables or distributions that shall be required
to be made on any 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 5.06) 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 Controlling Class as of the preceding Distribution
Date or of the Holders of Certificates evidencing greater than a majority of the
ownership interest in the Trust as of the preceding Distribution Date, in each
case without the consent of the Indenture Trustee and the numbers of Financial
Parties described in such Section.

          (c) Prior to the execution of any such amendment or consent, the
Indenture Trustee shall furnish written notification to the Rating Agencies of
the substance of such amendment or consent as provided to the Indenture Trustee.

          (d) Promptly after the execution of any such amendment or consent, the
Owner Trustee shall furnish written notification of the substance of such
amendment or consent to each Certificateholder, and the Indenture Trustee shall

          (e) It shall not be necessary for the consent of Financial Parties
pursuant to Section 5.01(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.

referred to in Section 5.02(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.

          (g) Notwithstanding any other provision of this Agreement, if the

null and void ab initio unless the Swap Counterparty consents in writing to such
amendment.

          (c) The Seller shall give each Trustee at least 60 days prior written
notice of any change in its jurisdiction of formation and shall file such

and (ii) reconciliation between payments or recoveries on (or with respect to)
each Receivable and the amounts from time to time deposited in the Collection

Receivable is owned by the Issuer and has been pledged by the Issuer to the
Indenture Trustee. Indication of the Issuer's ownership of a Receivable shall be
deleted from or modified on the Servicer's computer systems when, and only when,
the Receivable shall have been paid in full, repurchased by the Seller,
purchased by the Servicer or become a Liquidating Receivable.

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 Issuer
and has been pledged by the Issuer to the Indenture Trustee unless such
Receivable has been paid in full, repurchased by the Seller or purchased by the
Servicer.

          (g) The Seller will cause the Servicer to permit each Trustee and
their respective agents at any time to inspect, audit and make copies of and

previously included in the Owner Trust Estate.

          (h) The Seller will cause the Servicer to furnish to each Trustee at
any time upon request a list of all Receivables then held as part of the Owner
Trust Estate, together with a reconciliation of such list to the Composite
Schedule of Receivables and to each of the Servicer's Certificates furnished
before such request indicating removal of Receivables from the Owner Trust
Estate. Upon request, the Servicer shall furnish a copy of any such list to the
Seller. Each Trustee and the Seller shall hold any such list and the Composite
Schedule of Receivables for examination by interested parties during normal
business hours at their respective offices located at the addresses set forth in
Section 5.03.

          (i) The Seller will deliver to each Trustee promptly after the

financing statements and continuation statements have been executed and filed
that are necessary fully to preserve and protect the interest of the Issuer and
the Indenture Trustee in the Receivables, the Series 2002-B Portfolio Interest
and the Series 2002-B Portfolio Certificate and reciting the details of such

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) Use of "related" as used in this Appendix and the Basic Documents,
with respect to any Distribution Date, the "related Determination Date," the
"related Monthly Period," and the "related Record Date" will mean the
Determination Date, the Monthly Period, and the Record Date, respectively,
immediately preceding such Distribution Date. With respect to any Purchase Date,
the "related Cutoff Date" will mean the Cutoff Date established for the closing
of the purchase of receivables on that Purchase Date.

          (D) Use of "outstanding" etc. Whenever the term "outstanding Notes,"
"outstanding principal amount" and words of similar import are used in this
Appendix or any Basic Document for purposes of determining whether the
Noteholders of the requisite outstanding principal amount of the Notes have
given any request, demand, authorization, direction, notice, consent or waiver
hereunder or under any Basic Document, Notes owned by the Issuer, any other
obligor upon the Notes, the Seller or any Affiliate of any of the foregoing
Persons (it being understood that the Owner Trustee in its individual capacity
shall not be considered an Affiliate of any of the foregoing) shall be
disregarded and deemed not to be outstanding, except that, in determining
whether the Indenture Trustee shall be protected in relying upon any such
request, demand, authorization, direction, notice, consent or waiver, only Notes
that the Indenture Trustee knows to be so owned shall be so disregarded. Notes
so owned that have been pledged in good faith may be regarded as "outstanding"
if the pledgee establishes to the satisfaction of the Indenture Trustee the
pledgor's right so to act with respect to such Notes and that the pledgee is not
the Issuer, any other obligor upon the Notes, the Seller or any Affiliate of any
of the foregoing Persons.

          (E) 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

                                   App. A-38

<PAGE>

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.

          (F) 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.

          (G) UCC References. References to sections or provisions of Article 9
of the UCC in any of the Basic Documents shall be deemed to be automatically
updated to reflect the successor, replacement or functionally equivalent
sections or provisions of Revised Article 9, Secured Transactions (2000) at any
time in any jurisdiction which has made such revised article effective.

          (H) References to a Class of Notes. Unless otherwise specified,
references to a class of Notes, includes all the tranches included in such class
of Notes.
