                                    RECITALS

     A. Each of the Originators now owns, and from time to time hereafter will
own, Receivables.

     B. Buyer has been formed for the sole purpose of purchasing, or otherwise
acquiring by capital contribution, and reselling to the Agent for the benefit of
the Purchasers, all Receivables originated by each Originator.

     C. Each of the Originators intends to sell, and Buyer intends to purchase,
such Receivables, from time to time, as described herein.

     D. In addition, each of the Originators may, from time to time, contribute
capital to Buyer in the form of Contributed Receivables or cash.

     E. Performance Guarantor owns, directly or indirectly, one hundred percent
(100%) of the equity interests of each of the Originators and as such will

described in Recital C.

                                    AGREEMENT

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
hereinafter contained, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

                                   ARTICLE I
                         DEFINITIONS AND INTERPRETATION

     Section 1.01. Definitions. Capitalized terms used and not otherwise defined
herein shall have the meanings ascribed to them in Annex X.

     Section 1.02. Rules of Construction. For purposes of this Agreement, the
rules of construction set forth in Annex X shall govern. All Appendices hereto,
or expressly identified to this Agreement, are incorporated herein by reference

                                      Wabash National Corporation, NOAMTC, Inc.,

                                     Receivables Sale and Contribution Agreement
<PAGE>


                                   ARTICLE II
                               SALE OF RECEIVABLES

     Section 2.01. Agreement to Sell.

     (a) Sale of Receivables. Subject to the terms and conditions hereof, each
of the Originators agrees to sell or contribute, without recourse except to the
extent specifically provided herein, to Buyer on the Closing Date and on each
Business Day thereafter including the Facility Termination Date (the Closing
Date and each such Business Day, a "Transfer Date") all Receivables owned by it
on each such Transfer Date, and Buyer agrees to purchase or acquire as a capital
contribution all such Receivables on each such Transfer Date. All such Transfers
by either Originator shall be evidenced by a single certificate of assignment
substantially in the form of Exhibit 2.01(a) (the "Receivables Assignment"), and
each of the Originators and Buyer shall execute and deliver the Receivables
Assignment on or before the Closing Date.

     (b) Determination of Sold Receivables. It is understood and agreed that
each Transfer of a Receivable on a Transfer Date subsequent to the Closing Date
shall occur immediately upon creation of such Receivable. On and as of each
Transfer Date, all Receivables owned by each of the Originators and not
previously acquired by Buyer shall be identified for sale to Buyer such that the
Sale Price to be paid by Buyer therefor does not exceed the amount of cash
available to Buyer for the payment thereof (each such Receivable identified for
sale, individually, a "Sold Receivable" and, collectively, the "Sold
Receivables"). The Sold Receivables will be identified by reference to the
General Trial Balance of each of the Originators.

     (c) Payment of Sale Price. In consideration for each Sale of Sold
Receivables hereunder by an Originator, Buyer shall pay to the applicable
Originator on the Transfer Date therefor the Sale Price therefor in Dollars in
immediately available funds. All such payments by Buyer under this Section
2.01(c) shall be effected by means of a wire transfer on the day when due to
such account or accounts as the applicable Originator may designate.

     (d) Determination of Contributed Receivables. To the extent that, on and as
of any Transfer Date, Receivables owned by each of the Originators which do not
constitute Sold Receivables pursuant to Section 2.01(b), then each of the
Originators shall, unless it has delivered an Election Notice (as defined below)
to Buyer, contribute such Receivables to Buyer as a capital contribution (each
such contributed Receivable, individually, a "Contributed Receivable," and
collectively, the "Contributed Receivables"). If any Originator elects not to
contribute Receivables to Buyer on any Transfer Date, or if any Receivables
eligible for sale and owned by such Originator are not sold on any Transfer
Date, such Originator shall deliver to Buyer not later than 5:00 p.m. (New York
City time) on such Transfer Date a notice of election thereof (each such notice,
an "Election Notice").

                                     Receivables Sale and Contribution Agreement
<PAGE>


     (e) Ownership of Transferred Receivables. On and after each Transfer Date
and after giving effect to the Sales to be made on each such date, Buyer shall
own the Transferred Receivables and no Originator shall take any action
inconsistent with such ownership.

     (f) Reconstruction of General Trial Balance. If at any time any Originator
fails to generate its General Trial Balance, Buyer shall have the right to
reconstruct such General Trial Balance so that a determination of the Sold
Receivables and Contributed Receivables can be made pursuant to Section 2.01(b).
Each of the Originators agrees to cooperate with such reconstruction, including
by delivery to Buyer, upon Buyer's request, of copies of all applicable
Contracts and Records.

     (g) Servicing of Receivables. So long as no Event of Servicer Termination
shall have occurred and be continuing and no Successor Servicer has assumed the
responsibilities and obligations of the Servicer pursuant to Section 9.02 of the
Purchase Agreement, the Servicer shall (i) conduct the servicing, administration
and collection of the Transferred Receivables and shall take, or cause to be
taken, all such actions as may be necessary or advisable to service, administer
and collect the Transferred Receivables, all in accordance with (A) the terms of
the Purchase Agreement, (B) customary and prudent servicing procedures for trade
receivables of a similar type and (C) all applicable laws, rules and
regulations, and (ii) hold all Contracts and other documents and incidents
relating to the Transferred Receivables in trust for the benefit of Buyer, as
the owner thereof, and for the sole purpose of facilitating the servicing of the
Transferred Receivables in accordance with the terms of the Purchase Agreement.

     Section 2.02. Grant of Security Interest. The parties hereto intend that
each Transfer of Receivables pursuant to this Agreement shall constitute an
absolute sale, transfer and assignment of all of the applicable Originator's
rights, title and interest in and to the Transferred Receivables to Buyer, and
not a loan from Buyer to the Originators secured by the Transferred Receivables.
Notwithstanding the foregoing, in addition to and not in derogation of any
rights now or hereafter acquired by Buyer under Section 2.01 hereof, the parties
agree that if for any reason the Transfer of a Receivable is treated as a loan,
each of the Originators does hereby grant, to the Buyer a continuing security
interest in all of such Originator's right, title and interest in, to and under
the Originator Collateral whether now owned or hereafter acquired by such
Originator to secure the obligations of such Originator to the Buyer hereunder
(including, if and to the extent that any Transfer is recharacterized as a
transfer for security, the repayment of a loan deemed to have been made by the
Buyer in the amount of the Sale Price with respect thereto and which secures the
Buyer's right to receive all Collections of the Transferred Receivables as
otherwise contemplated under this Agreement), which security interest shall be
prior to all Adverse Claims thereto.

conditions were in fact so satisfied.

                                     Receivables Sale and Contribution Agreement

     including the timely filing of all reports required under the Code or
     ERISA, (y) neither Performance Guarantor, any Originator nor any ERISA
     Affiliate has failed to make any contribution or pay any amount due as
     required by either Section 412 of the Code or Section 302 of ERISA or the

     claims for benefits in the normal course), sanctions, actions or lawsuits,

     sponsor of any Plan; (D) neither Performance Guarantor, any Originator nor
     any ERISA Affiliate has incurred or reasonably expects to incur any
     liability as a result of a complete or partial withdrawal from a
     Multiemployer Plan; (E) within the last five years no Title IV Plan with
     Unfunded Liabilities has been transferred outside of the "controlled group"
     (within the meaning of Section 4001(a)(14) of ERISA) of Performance
     Guarantor, any Originator or any ERISA Affiliate; (F) Equity Interests of
     Performance Guarantor, the Originators and their ERISA Affiliates make up,
     in the aggregate, no more than 10% of the assets of any Plan, measured on
     the basis of fair market value as of the last valuation date of any Plan.

     (p) Brokers. No broker or finder acting on behalf of Performance Guarantor
or any Originator was employed or utilized in connection with this Agreement or
the other Related Documents or the transactions contemplated hereby or thereby
and neither Performance Guarantor nor any Originator has any obligation to any
Person in respect of any finder's or brokerage fees in connection therewith.

     (q) Margin Regulations. Neither Originator nor the Performance Guarantor is

in the business of extending credit for the purpose of "purchasing" or
"carrying" any "margin security" as such terms are defined in Regulation U of

securities being referred to herein as "Margin Stock"). Neither Originator nor
Performance Guarantor owns any Margin Stock, and no portion of the Sale Price

purchasing or carrying any Margin Stock, for the purpose of reducing or retiring
any Indebtedness that was originally incurred to purchase or carry any Margin
Stock or for any other purpose that might

<PAGE>

cause any portion of such proceeds to be considered a "purpose credit" within
the meaning of Regulations T, U or X of the Federal Reserve Board. Neither
Originator nor Performance Guarantor will take or permit to be taken any action
that might cause any Related Document to violate any regulation of the Federal
Reserve Board.

     (r) Nonapplicability of Bulk Sales Laws. No transaction contemplated by
this Agreement or any of the other Related Documents requires compliance with
any bulk sales act or similar law.

     (s) Warranty Policy. Attached hereto as Schedule 4.01(s) is a true and

subject to regulation under the Public Utility Holding Company Act of 1935, the
Federal Power Act, or any other federal or state statute that restricts or
limits its ability to incur Indebtedness or to perform its obligations hereunder
or under the other Related Documents. The purchase or acquisition of Transferred
Receivables by Buyer hereunder, the application of the Sale Price for the
foregoing and the consummation of the transactions contemplated by this
Agreement and the other Related Documents will not violate any provision of any
such statute or any rule, regulation or order issued by the Securities and
Exchange Commission.

the complete account number therefor, in each case as of the Closing Date.

     (w) Representations and Warranties in Other Related Documents. Each of the
representations and warranties of Performance Guarantor and the Originators
contained in the Related Documents (other than this Agreement) is true and
correct in all material respects and Performance Guarantor and each Originator
hereby makes each such representation and warranty to, and for the benefit of,
the Purchasers and the Agent as if the same were set forth in full herein, and

rights to the Agent for the benefit of the Purchasers and their respective
successors and assigns as contemplated in Section 4.02(f).

     (x) Receivables. With respect to each Receivable designated as an Eligible

     prior to its Transfer to Buyer;

          (ii) prior to its Transfer to Buyer, such Receivable was owned by the
     applicable Originator free and clear of any Adverse Claim (other than
     Permitted Originator Encumbrances set forth in clauses (a), (h) and (j) of
     the definition of such term), and such Originator had the full right, power
     and authority to sell, contribute, assign, transfer and pledge its interest
     therein as contemplated under this Agreement and the other Related
     Documents and, upon such Transfer, Buyer will acquire valid and properly
     perfected title to and the sole record and beneficial ownership interest in
     such Receivable, free and clear of any Adverse Claim and, following such
     Transfer, such Receivable will not be subject to any Adverse Claim as a
     result of any action or inaction on the part of such Originator;

          (iii) the Transfer of each such Receivable pursuant to this Agreement
     and the Receivables Assignment constitutes, as applicable, a valid sale,
     contribution, transfer, assignment, setover and conveyance to Buyer of all
     right, title and interest of such Originator in and to such Receivable; and

          (iv) none of the Performance Guarantor nor the Originators has any
     knowledge of any fact (including any defaults by the Obligor thereunder on
     any other Receivable) that would cause it or should have caused it to
     expect that any payments on such Receivable will not be paid in full when
     due or to expect any other Material Adverse Effect.

     The representations and warranties described in this Section 4.01 shall
survive the Transfer of the Transferred Receivables to Buyer, any subsequent
assignment of the Transferred Receivables by Buyer, and the termination of this
Agreement and the other Related Documents and shall continue until the
indefeasible payment in full of all Transferred Receivables.

     Section 4.02. Affirmative Covenants of Performance Guarantor and each

                                     Receivables Sale and Contribution Agreement
<PAGE>

     (a) Offices and Records. Performance Guarantor and each Originator shall
maintain its principal place of business and chief executive office and the
office at which it keeps its Records at the respective locations specified in
Schedule 4.01(b) or, upon 30 days' prior written notice to Buyer and the Agent,
at such other location in a jurisdiction where all action requested by Buyer,
the Purchasers or the Agent pursuant to Section 9.13 shall have been taken with
respect to the Transferred Receivables. Each Originator shall at its own cost
and expense, for not less than three years from the date on which each
Transferred Receivable was originated, or for such longer period as may be
required by law, maintain adequate Records with respect to such Transferred
Receivable, including records of all payments received, credits granted and
merchandise returned with respect thereto. Each Originator will, (A) at all
times from and after the date hereof, clearly and conspicuously mark its
computer and master data processing books and records with a legend describing
the Buyer's interest in the Receivables, and (B) segregate (from all other
receivables then owned by the Originators) all contracts relating to each

employees and agents access to its properties (including properties utilized in
connection with the collection, processing or servicing of the Transferred
Receivables), facilities, advisors and employees (including officers) and to the
Originator Collateral, (ii) permit Buyer, the Servicer or the Agent and any of
their respective officers, employees and agents, to inspect, audit and make
extracts from its books and records, including all Records, (iii) permit Buyer,
the Servicer or the Agent and their respective officers, employees and agents,
to inspect, review and evaluate the Transferred Receivables and other Originator
Collateral, as applicable, and (iv) permit Buyer, the Servicer or the Agent and
their respective officers, employees and agents to discuss matters relating to
the Transferred Receivables or Performance Guarantor's or any Originator's
performance under this Agreement or the affairs, finances and accounts of
Performance Guarantor and the Originators with any of their officers, directors,
employees, representatives or agents (in each case, with those Persons having
knowledge of such matters) and with their independent certified public
accountants. If an Incipient Termination Event or a Termination Event shall have
occurred and be continuing, or the Agent, in good faith, believes that an
Incipient Termination Event or a Termination Event is imminent or deems the
Agent's rights or interests (on behalf of the Purchasers) in the Transferred
Receivables or the Originator Collateral insecure, Performance Guarantor and
each Originator shall provide such access at all times and without advance
notice and shall provide Buyer, the Servicer or the Agent with access to its
suppliers and customers. Performance Guarantor and each Originator shall make
available to Buyer, the Servicer or the Agent and their respective counsel, as
quickly as is possible under the circumstances, originals or copies of all books
and records, including Records, that Buyer, the Servicer or the Agent may

indemnify and hold harmless each Buyer Indemnified Person from and against any
and all Indemnified Amounts that may be claimed or asserted against or incurred
by any such Buyer Indemnified Person in connection with or arising out of the
transactions contemplated under this Agreement or under any other Related
Document, any actions or failures to act in connection therewith, including any
and all legal costs and expenses arising out of or incurred in connection with
disputes between or among any parties to any of the Related Documents, or in
respect of any Transferred Receivable or any Contract therefor or the use by
Originator of the Sale Price therefor; provided, that neither Performance
Guarantor nor the Originators shall be liable for any indemnification to a Buyer
Indemnified Person to the extent that any such Indemnified Amounts result solely
from (a) such Buyer Indemnified Person's gross negligence or willful misconduct,
as finally determined by a court of competent jurisdiction, (b) recourse for
uncollectible or uncollected Transferred Receivables due to the lack of
creditworthiness of the Obligor or the occurrence of any event of bankruptcy
with respect to such Obligor, or (c) any income tax or franchise tax incurred by

such tax results from a breach of or default under this Agreement or any other
Related Document. Subject to the exceptions set forth in clauses (a), (b) and
(c) of the immediately preceding sentence but otherwise without limiting the
generality of the foregoing, each Originator and Performance Guarantor shall pay
on demand to each Buyer Indemnified Person any and all Indemnified Amounts

     other information delivered by Performance Guarantor or an Originator
     pursuant hereto or thereto that shall have been incorrect in any material
     respect when made or deemed made or delivered;

          (ii) the failure by Performance Guarantor or any Originator to comply
     with any term, provision or covenant contained in this Agreement, any other

     Transferred Receivable or Contract therefor, or the nonconformity of any
     Transferred Receivable or the Contract therefor with any such applicable

          (iv) any dispute, claim, offset or defense of any Obligor (other than
     its discharge in bankruptcy) to the payment of any Receivable that is the
     subject of a Transfer hereunder (including a defense based on such
     Receivable or the Contract therefor not being a legal, valid and binding
     obligation of such Obligor enforceable against it in accordance with its
     terms), or any other claim resulting from the sale of the merchandise or
     services giving rise to such Receivable or the furnishing or failure to
     furnish such merchandise or services or relating to collection activities
     with respect to such Receivable (if such collection activities were
     performed by Performance Guarantor or any Originator or any Affiliate
     acting as the Servicer or a Sub-Servicer), except to the extent that such
     dispute, claim, offset or defense results solely from any action or
     inaction on the part of Buyer;

     connection with merchandise, insurance or services that is the subject of
     any Contract;

     Buyer Indemnified Person for which neither Performance Guarantor nor any
     Originator or any of its Affiliates is at fault, as finally determined by a
     court of competent jurisdiction; or

                               COLLATERAL SECURITY

     Section 7.01. Security Interest. To secure the prompt and complete payment,
performance and observance of any and all recourse and indemnity obligations of
each of the Originators to Buyer, including those set forth in Sections 4.02(p),
4.05, 5.01 and 9.14, and to induce Buyer to enter into this Agreement in
accordance with the terms and conditions hereof, each Originator hereby grants,
assigns, conveys, pledges, hypothecates and transfers to Buyer a Lien upon all
of such Originator's right, title and interest in, to and under the following
property, whether now owned by or owing to, or hereafter acquired by or arising
in favor of, such Originator (including under any trade names, styles or
derivations of such Originator), and whether owned by or consigned by or to, or
leased from or to, such Originator, and regardless of where located (all of
which being hereinafter collectively referred to as the "Originator

<PAGE>

     (b) all monies, securities and other property now or hereafter in the
possession or custody of, or in transit to, Buyer, for any purpose (including
safekeeping, collection or pledge), from or for either of the Originators, or as
to which either of the Originators may have any right or power, and all of
Buyer's credits and balances with either of the Originators existing at any

     (c) to the extent not otherwise included, customer lists, credit files and

Originator shall remain liable under any and all of the Receivables originated

or obligated in any manner to perform or fulfill any of the obligations of
either of the Originators under or pursuant to any such Receivable, Contract or

nature or the sufficiency of any payment received by it or the sufficiency of
any performance by any party under any such Receivable, Contract or Originator
Collateral, or to present or file any claims, or to take any action to collect
or enforce any performance or the payment of any amounts that may have been
assigned to it or to which it may be entitled at any time or times.

                             PERFORMANCE UNDERTAKING

     Section 8.01. Guaranty of Performance of Guaranteed Obligations.
Performance Guarantor hereby guarantees to Buyer, the full and punctual payment
and performance by each


                                       26

<PAGE>

Originator and each Servicer that is a Subsidiary or an Affiliate of Performance
Guarantor (each, an "Affiliated Servicer") of its respective Guaranteed
Obligations. The undertaking embodied in this Article VIII (this "Undertaking")
is an absolute, unconditional and continuing guaranty of the full and punctual
performance of all Guaranteed Obligations under this Agreement or the Purchase
Agreement, as applicable, and each other document executed and delivered by
either of the Originators or Affiliated Servicer pursuant to such agreements, as
applicable, and is in no way conditioned upon any requirement that Buyer first
attempt to collect any amounts owing by the Originators or Affiliated Servicer
to Buyer, the Agent or the Purchasers from any other Person or resort to any
collateral security, any balance of any deposit account or credit on the books
of Buyer, the Agent or the Purchasers in favor of either of the Originators or
Affiliated Servicer or any other Person or other means of obtaining payment.
Should either of the Originators or Affiliated Servicer default in the payment
or performance of any of its Guaranteed Obligations, Buyer (or its assigns) may
cause the immediate performance by Performance Guarantor of such Guaranteed
Obligations and cause any payment of Guaranteed Obligations to become forthwith
due and payable to Buyer (or its assigns) by Performance Guarantor, without
demand or notice of any nature (other than as expressly provided herein), all of
which are hereby expressly waived by Performance Guarantor. Notwithstanding the
foregoing, this Undertaking is not a guarantee of the collection of any of the
Receivables and Performance Guarantor shall not be responsible for any
Guaranteed Obligations to the extent the failure to perform such Guaranteed
Obligations by either of the Originators or Affiliated Servicer results from
Receivables being uncollectible on account of the insolvency, bankruptcy or lack
of creditworthiness of the related Obligor; provided that nothing herein shall
relieve either of the Originators or Affiliated Servicer from performing in full
its Guaranteed Obligations under the Related Documents to which it is a party or
Performance Guarantor of its Undertaking hereunder with respect to the full
performance of such duties.

     Section 8.02. Performance Guarantor's Further Agreements to Pay.
Performance Guarantor further agrees, as the principal obligor and not as a
guarantor only, to pay to Buyer (and its assigns), forthwith upon demand in
funds immediately available to Buyer, all reasonable costs and expenses
(including court costs and reasonable legal expenses) incurred or expended by
Buyer in connection with the Guaranteed Obligations, this Undertaking and the
enforcement thereof, together with interest on amounts recoverable under this
Undertaking from the time when such amounts become due until payment, at a rate
of interest (computed for the actual number of days elapsed based on a 360-day
year) equal to the sum of the Index Rate plus the Daily Margin plus the Daily
Default Margin per annum, such rate of interest changing when and as the Index
Rate changes.

     Section 8.03. Waivers by Performance Guarantor. Performance Guarantor
waives notice of acceptance of this Undertaking, notice of any action taken or
omitted by Buyer (or its assigns) in reliance on this undertaking, and any
requirement that Buyer (or its assigns) be diligent or prompt in making demands
under this undertaking, giving notice of any Termination Event, Event of
Servicer Termination, other default or omission by either of the Originators or


                                       27

Affiliated Servicer or asserting any other rights of Buyer under this
Undertaking. Performance Guarantor warrants that it has adequate means to obtain
from the Originators and Affiliated Servicer, on a continuing basis, information
concerning their financial condition, and that it is not relying on Buyer to
provide such information, now or in the future. Performance Guarantor also
irrevocably waives all defenses (i) that at any time may be available in respect
of the Guaranteed Obligations by virtue of any statute of limitations,
valuation, stay, moratorium law or other similar law now or hereafter in effect
or (ii) that arise under the law of suretyship, including impairment of
collateral. Buyer (and its assigns) shall be at liberty, without giving notice
to or obtaining the assent of Performance Guarantor and without relieving
Performance Guarantor of any liability under this Undertaking, to deal with each
of the Originators and Affiliated Servicer and with each other party who now is
or after the date hereof becomes liable in any manner for any of the Guaranteed
Obligations, in such manner as Buyer in its sole discretion deems fit, and to
this end Performance Guarantor agrees that the validity and enforceability of
this Undertaking, shall not be impaired or affected by any of the following: (a)
any extension, modification or renewal of, or indulgence with respect to, or
substitutions for, the Guaranteed Obligations or any part thereof or any
agreement relating thereto at any time; (b) any failure or omission to enforce
any right, power or remedy with respect to the Guaranteed Obligations or any
part thereof or any agreement relating thereto, or any collateral securing the
Guaranteed Obligations or any part thereof; (c) any waiver of any right, power
or remedy or of any Termination Event, Event of Servicer Termination, or default
with respect to the Guaranteed Obligations or any part thereof or any agreement
relating thereto; (d) any release, surrender, compromise, settlement, waiver,
subordination or modification, with or without consideration, of any other
obligation of any Person or entity with respect to the Guaranteed Obligations or
any part thereof; (e) the enforceability or validity of the Guaranteed
Obligations or any part thereof or the genuineness, enforceability or validity
of any agreement relating thereto or with respect to the Guaranteed Obligations
or any part thereof; (f) the application of payments received from any source to
the payment of any payment obligations of either Originator or Affiliated
Servicer or any part thereof or amounts which are not covered by this
Undertaking even though Buyer (or its assigns) might lawfully have elected to
apply such payments to any part or all of the payment obligations of Originators
or Affiliated Servicer or to amounts which are not covered by this Undertaking;
(g) the existence of any claim, setoff or other rights which Performance
Guarantor may have at any time against Originators or Affiliated Servicer in
connection herewith or any unrelated transaction; (h) any assignment or transfer
of the Guaranteed Obligations or any part thereof; or (i) any failure on the
part of Originators or Affiliated Servicer to perform or comply with any term of
the Agreements or any other document executed in connection therewith or
delivered thereunder, all whether or not Performance Guarantor shall have had
notice or knowledge of any act or omission referred to in the foregoing clauses
(a) through (i) of this Section 8.03.

     Section 8.04. Unenforceability of Guaranteed Obligations Against
Originators or Affiliated Servicer. Notwithstanding (a) any change of ownership
of Originators or Affiliated Servicer or the insolvency, bankruptcy or any other
change in the legal status of Originators or Affiliated Servicer; (b) any change
in or the imposition of any law, decree, regulation or other


                                       28

governmental act which does or might impair, delay or in any way affect the
validity, enforceability or the payment when due of the Guaranteed Obligations;
(c) the failure of either of the Originators, Affiliated Servicer or Performance
Guarantor to maintain in full force, validity or effect or to obtain or renew
when required all governmental and other approvals, licenses or consents
required in connection with the Guaranteed Obligations or this Undertaking, or
to take any other action required in connection with the performance of all
obligations pursuant to the Guaranteed Obligations or this Undertaking; or (d)
if any of the moneys included in the Guaranteed Obligations have become
irrecoverable from either of the Originators or Affiliated Servicer for any
other reason other than final payment in full of the payment Guaranteed
Obligations in accordance with their terms, this Undertaking shall nevertheless
be binding on Performance Guarantor. This Undertaking shall be in addition to
any other guaranty or other security for the Guaranteed Obligations, and it
shall not be rendered unenforceable by the invalidity of any such other guaranty
or security. In the event that acceleration of the time for payment of any of
the Guaranteed Obligations is stayed upon the insolvency, bankruptcy or
reorganization of either of the Originators or Affiliated Servicer or for any
other reason with respect to either of the Originators or Affiliated Servicer,
all such amounts then due and owing with respect to the Guaranteed Obligations
under the terms of the Agreements, or any other agreement evidencing, securing
or otherwise executed in connection with the Guaranteed Obligations, shall be
immediately due and payable by Performance Guarantor.

     Section 8.05. Subrogation; Subordination. Notwithstanding anything to the
contrary contained herein, until the Guaranteed Obligations are paid in full,
Performance Guarantor: (a) will not enforce or otherwise exercise any right of
subrogation to any of the rights of Buyer, the Agent or the Purchasers against
either of the Originators or Affiliated Servicer, (b) hereby waives all rights
of subrogation (whether contractual, under Section 509 of the United States
Bankruptcy Code, at law or in equity or otherwise) to the claims of Buyer, the
Agent and the Purchasers against either of the Originators or Affiliated
Servicer and all contractual, statutory or legal or equitable rights of
contribution, reimbursement, indemnification and similar rights and "claims" (as
such term is defined in the United States Bankruptcy Code) which Performance
Guarantor might now have or hereafter acquire against either of the Originators
or Affiliated Servicer that arise from the existence or performance of
Performance Guarantor's obligations hereunder, (c) will not claim any setoff,
recoupment or counterclaim against either of the Originators or Affiliated
Servicer in respect of any liability of Performance Guarantor to either of the
Originators or Affiliated Servicer and (d) waives any benefit of and any right
to participate in any collateral security which may be held by the Agent or any
Purchaser. The payment of any amounts due with respect to any Indebtedness of
either of the Originators or Affiliated Servicer now or hereafter owed to
Performance Guarantor is hereby subordinated to the prior payment in full of all
of the Guaranteed Obligations. Performance Guarantor agrees that, after the
occurrence of any default in the payment or performance of any of the Guaranteed
Obligations, Performance Guarantor will not demand, sue for or otherwise attempt
to collect any such Indebtedness of either of the Originators or Affiliated
Servicer to Performance Guarantor until all of the Guaranteed Obligations shall
have been paid and performed in full. If, notwithstanding the foregoing
sentence, Performance Guarantor shall collect, enforce or receive any amounts in


                                       29

                                     Receivables Sale and Contribution Agreement
<PAGE>

respect of such Indebtedness while any Guaranteed Obligations are still
unperformed or outstanding, such amounts shall be collected, enforced and
received by Performance Guarantor as trustee for Buyer (and its assigns) and be
paid over to Buyer (or its assigns) on account of the Guaranteed Obligations
without affecting in any manner the liability of Performance Guarantor under the
other provisions of this Undertaking. The provisions of this Section shall be
supplemental to and not in derogation of any rights and remedies of Buyer under
any separate subordination agreement which Buyer may at any time and from time
to time enter into with Performance Guarantor.

     Section 8.06. Termination of Performance Undertaking. Performance
Guarantor's obligations hereunder shall continue in full force and effect until
all Seller Secured Obligations are finally paid and satisfied in full and the
Purchase Agreement is terminated, provided that this Undertaking shall continue
to be effective or shall be reinstated, as the case may be, if at any time
payment or other satisfaction of any of the Guaranteed Obligations is rescinded
or must otherwise be restored or returned upon the bankruptcy, insolvency, or
reorganization of either of the Originators or Affiliated Servicer or otherwise,
as though such payment had not been made or other satisfaction occurred, whether
or not Buyer (or its assigns) is in possession of this Undertaking. No
invalidity, irregularity or unenforceability by reason of the federal bankruptcy
code or any insolvency or other similar law, or any law or order of any
government or agency thereof purporting to reduce, amend or otherwise affect the
Guaranteed Obligations shall impair, affect, be a defense to or claim against
the obligations of Performance Guarantor under this Undertaking.

     Section 8.07. Effect of Bankruptcy. This Performance Undertaking shall
survive the insolvency of either of the Originators or Affiliated Servicer and
the commencement of any case or proceeding by or against either of the
Originators or Affiliated Servicer under the federal bankruptcy code or other
federal, state or other applicable bankruptcy, insolvency or reorganization
statutes. No automatic stay under the federal bankruptcy code with respect to
either of the Originators or Affiliated Servicer or other federal, state or
other applicable bankruptcy, insolvency or reorganization statutes to which
either of the Originators or Affiliated Servicer is subject shall postpone the
obligations of Performance Guarantor under this Undertaking.

     Section 8.08. Setoff. Regardless of the other means of obtaining payment of
any of the Guaranteed Obligations, Buyer (and its assigns) is hereby authorized
at any time and from time to time, without notice to Performance Guarantor (any
such notice being expressly waived by Performance Guarantor) and to the fullest
extent permitted by law, to set off and apply any deposits and other sums
against the obligations of Performance Guarantor under this Undertaking, whether
or not Buyer (or any such assign) shall have made any demand under this
Undertaking and although such obligations may be contingent or unmatured.

provided that each such declaration or other communication shall be deemed to
have been validly delivered to the Agent under this Agreement upon delivery to
the Agent in accordance with the terms of the Purchase Agreement. The giving of
any notice required hereunder may be waived in writing by the party entitled to
receive such notice. Failure or delay in delivering copies of any notice,
demand, request, consent, approval, declaration or other communication to any
Person (other than Buyer) designated in any written communication provided
hereunder to receive copies shall in no way adversely affect the effectiveness
of such notice, demand, request,

consent, approval, declaration or other communication. Notwithstanding the
foregoing, whenever it is provided herein that a notice is to be given to any
other party hereto by a specific time, such notice shall only be effective if
actually received by such party prior to such time, and if such notice is
received after such time or on a day other than a Business Day, such notice
shall only be effective on the immediately succeeding Business Day.

     Section 9.02. No Waiver; Remedies. Buyer's failure, at any time or times,
to require strict performance by any Originators or Performance Guarantor of any
provision of this Agreement or the Receivables Assignment shall not waive,
affect or diminish any right of Buyer thereafter to demand strict compliance and
performance herewith or therewith. Any suspension or waiver of any breach or
default hereunder shall not suspend, waive or affect any other breach or default
whether the same is prior or subsequent thereto and whether the same or of a
different type. None of the undertakings, agreements, warranties, covenants and
representations of the Originators or Performance Guarantor contained in this
Agreement or the Receivables Assignment, and no breach or default by any
Originator or Performance Guarantor hereunder or thereunder, shall be deemed to
have been suspended or waived by Buyer unless such waiver or suspension is by an
instrument in writing signed by an officer of or other duly authorized signatory
of Buyer and directed to Performance Guarantor or such Originator, as
applicable, specifying such suspension or waiver. Buyer's rights and remedies
under this Agreement shall be cumulative and nonexclusive of any other rights
and remedies that Buyer may have under any other agreement, including the other
Related Documents, by operation of law or otherwise. Recourse to the Originator
Collateral shall not be required.

     Section 9.03. Successors and Assigns. This Agreement shall be binding upon
and shall inure to the benefit of Originators, Performance Guarantor and Buyer
and their respective successors and permitted assigns, except as otherwise
provided herein. Neither Performance Guarantor nor any Originator may assign,
transfer, hypothecate or otherwise convey its rights, benefits, obligations or
duties hereunder without the prior express written consent of Buyer, the
Purchasers and the Agent. Any such purported assignment, transfer, hypothecation
or other conveyance by any Originator or Performance Guarantor without the prior
express written consent of Buyer, the Purchasers and the Agent shall be void.
Each Originator and Performance Guarantor acknowledges that, to the extent
permitted under the Purchase Agreement, Buyer may assign its rights granted
hereunder, including the benefit of any indemnities under Article V and any of
its rights in the Originator Collateral granted under Article VII, and upon such
assignment, such assignee shall have, to the extent of such assignment, all
rights of Buyer hereunder and, to the extent permitted under the Purchase
Agreement, may in turn assign such rights. Each Originator and Performance
Guarantor agrees that, upon any such assignment, such assignee may enforce
directly, without joinder of Buyer, the rights set forth in this Agreement. All
such assignees, including parties to the Purchase Agreement in the case of any
assignment to such parties, shall be third party beneficiaries of, and shall be
entitled to enforce Buyer's rights and remedies under, this Agreement to the
same extent as if they were parties hereto. Without limiting the generality of
the foregoing, all notices to be provided to the Buyer hereunder shall be
delivered to both the Buyer and the Agent under the Purchase Agreement, and
shall be effective

only upon such delivery to the Agent. The terms and provisions of this Agreement
are for the purpose of defining the relative rights and obligations of each
Originator, Performance Guarantor and Buyer with respect to the transactions
contemplated hereby and, except for the Purchasers and the Agent, no Person
shall be a third party beneficiary of any of the terms and provisions of this
Agreement.

     Section 9.04. Termination; Survival of Obligations.

     (a) This Agreement shall create and constitute the continuing obligations
of the parties hereto in accordance with its terms, and shall remain in full
force and effect until the Termination Date.

     (b) Except as otherwise expressly provided herein or in any other Related
Document, no termination or cancellation (regardless of cause or procedure) of
any commitment made by Buyer under this Agreement shall in any way affect or
impair the obligations, duties and liabilities of any Originator, Performance
Guarantor or the rights of Buyer relating to any unpaid portion of any and all
recourse and indemnity obligations of Originator and Performance Guarantor to
Buyer, including those set forth in Sections 4.02(p), 4.05, 5.01 and 9.14, due
or not due, liquidated, contingent or unliquidated or any transaction or event
occurring prior to such termination, or any transaction or event, the
performance of which is required after the Facility Termination Date. Except as
otherwise expressly provided herein or in any other Related Document, all
undertakings, agreements, covenants, warranties and representations of or
binding upon Originators and Performance Guarantor, and all rights of Buyer
hereunder, all as contained in the Related Documents, shall not terminate or
expire, but rather shall survive any such termination or cancellation and shall
continue in full force and effect until the Termination Date; provided, that the
rights and remedies pursuant to Sections 4.02(p), 4.05, the indemnification and
payment provisions of Article V, and the provisions of Sections 4.04(j), 9.03,
9.12 and 9.14 shall be continuing and shall survive any termination of this
Agreement.

     Section 9.05. Complete Agreement; Modification of Agreement. This Agreement
and the other Related Documents constitute the complete agreement between the
parties with respect to the subject matter hereof and thereof, supersede all
prior agreements and understandings relating to the subject matter hereof and
thereof, and may not be modified, altered or amended except as set forth in
Section 9.06.

     Section 9.06. Amendments and Waivers. No amendment, modification,
termination or waiver of any provision of this Agreement or any of the other
Related Documents, or any consent to any departure by any Originator or
Performance Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by each of the parties hereto and the Purchasers
and the Agent. No consent or demand in any case shall, in itself, entitle any
party to any other consent or further notice or demand in similar or other
circumstances.

     Section 9.07. GOVERNING LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL.

     (a) THIS AGREEMENT AND EACH RELATED DOCUMENT (EXCEPT TO THE EXTENT THAT ANY
RELATED DOCUMENT EXPRESSLY PROVIDES TO THE CONTRARY) AND THE OBLIGATIONS ARISING
HEREUNDER AND THEREUNDER SHALL IN ALL RESPECTS, INCLUDING ALL MATTERS OF
CONSTRUCTION, VALIDITY AND PERFORMANCE, BE GOVERNED BY, AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF ILLINOIS (WITHOUT REGARD
TO CONFLICTS OF LAW PRINCIPLES), EXCEPT TO THE EXTENT THAT THE PERFECTION,
EFFECT OF PERFECTION OR PRIORITY OF THE INTERESTS OF THE BUYER IN THE
RECEIVABLES OR REMEDIES HEREUNDER OR THEREUNDER, IN RESPECT THEREOF, ARE
GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF ILLINOIS, AND ANY
APPLICABLE LAWS OF THE UNITED STATES OF AMERICA.

     (b) EACH PARTY HERETO HEREBY CONSENTS AND AGREES THAT THE STATE OR FEDERAL
COURTS LOCATED IN COOK COUNTY SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND
DETERMINE ANY CLAIMS OR DISPUTES BETWEEN THEM PERTAINING TO THIS AGREEMENT OR TO
ANY MATTER ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY RELATED DOCUMENT;
PROVIDED, THAT EACH PARTY HERETO ACKNOWLEDGES THAT ANY APPEALS FROM THOSE COURTS
MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF COOK COUNTY; PROVIDED
FURTHER, THAT NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE
BUYER FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION
TO REALIZE ON THE ORIGINATOR COLLATERAL OR ANY OTHER SECURITY FOR THE
OBLIGATIONS OF ORIGINATORS OR PERFORMANCE GUARANTOR ARISING HEREUNDER, OR TO
ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF BUYER. EACH PARTY HERETO
SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR SUIT
COMMENCED IN ANY SUCH COURT, AND EACH PARTY HERETO HEREBY WAIVES ANY OBJECTION
THAT SUCH PARTY MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER
VENUE OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE GRANTING OF SUCH LEGAL
OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT. EACH PARTY HERETO
HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS
ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS,
COMPLAINT AND OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED MAIL
ADDRESSED TO SUCH PARTY AT THE ADDRESS SET FORTH BENEATH ITS NAME ON THE
SIGNATURE PAGES HEREOF AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON

THE EARLIER OF SUCH PARTY'S ACTUAL RECEIPT THEREOF OR THREE DAYS AFTER DEPOSIT
IN THE UNITED STATES MAIL, PROPER POSTAGE PREPAID. NOTHING IN THIS SECTION SHALL
AFFECT THE RIGHT OF ANY PARTY HERETO TO SERVE LEGAL PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW.

     (c) BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX FINANCIAL
TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN EXPERIENCED AND
EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL LAWS TO APPLY
(RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT THEIR DISPUTES BE
RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE
BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, THE
PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT, OR
PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT OR
OTHERWISE, ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED AMONG THEM IN CONNECTION WITH THIS AGREEMENT OR ANY
RELATED DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

     Section 9.08. Counterparts. This Agreement may be executed in any number of
separate counterparts, each of which shall collectively and separately
constitute one agreement.

     Section 9.09. Severability. Wherever possible, each provision of this
Agreement shall be interpreted in such a manner as to be effective and valid
under applicable law, but if any provision of this Agreement shall be prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity without invalidating the remainder
of such provision or the remaining provisions of this Agreement.

     Section 9.10. Section Titles. The section titles and table of contents
contained in this Agreement are provided for ease of reference only and shall be
without substantive meaning or content of any kind whatsoever and are not a part
of the agreement between the parties hereto.

     Section 9.11. No Setoff. Neither Performance Guarantor's nor any
Originator's obligations under this Agreement shall be affected by any right of
setoff, counterclaim, recoupment, defense or other right any Originator or
Performance Guarantor might have against Buyer, the Purchasers or the Agent, all
of which rights are hereby expressly waived by the Originators and Performance
Guarantor.

Originators agrees that it shall not (and shall not permit any of its
Subsidiaries to) issue any news release or make any public announcement
pertaining to the transactions contemplated by this Agreement and the Related
Documents without the prior written consent of Buyer and the Agent (which
consent shall not be unreasonably withheld) unless such news release or public
announcement is required by law, in which case the Performance Guarantor or such
Originator, as the case may be, shall consult with Buyer and each of the
Committed Purchaser and the Conduit Purchaser prior to the issuance of such news
release or public announcement. Each of the Performance Guarantor and the
Originators may, however, disclose the general terms of the transactions
contemplated by this Agreement and the Related Documents to trade creditors,
suppliers and other similarly-situated Persons so long as such disclosure is not
in the form of a news release or public announcement.

     (a) Performance Guarantor shall, and shall cause each Originator to, and
each Originator shall, at its sole cost and expense, upon request of Buyer, the
Purchasers or the Agent, promptly and duly execute and deliver any and all
further instruments and documents and take such further actions that may be
necessary or desirable or that Buyer, the Purchasers or the Agent may request to
carry out more effectively the provisions and purposes of this Agreement or any
other Related Document or to obtain the full benefits of this Agreement and of
the rights and powers herein granted, including (i) using its best efforts to
secure all consents and approvals necessary or appropriate for the assignment to
or for the benefit of Buyer of any Transferred Receivable or Originator
Collateral held by an Originator or in which any Originator has any rights not
heretofore assigned, (ii) filing any financing or continuation statements under
the UCC with respect to the ownership interests or Liens granted hereunder or
under any other Related Document, (iii) transferring Originator Collateral to
Buyer's possession if such collateral consists of chattel paper or instruments
or if a Lien upon such collateral can be perfected only by possession, or if
otherwise requested by Buyer; and (iv) entering into "control agreements" (as
defined in the UCC with respect to any Originator Collateral to the extent that
a first priority Lien upon such Originator Collateral can be perfected only by
control. Each of the Originators hereby authorizes Buyer, the Purchasers and the
Agent to file any such financing or continuation statements without the
signature of each of the Originators to the extent permitted by applicable law.
A carbon, photographic or other reproduction of this Agreement or of any notice
or financing statement covering the Transferred Receivables, the Originator
Collateral or any part thereof shall be sufficient as a notice or financing
statement where permitted by law. If any amount payable under or in connection
with any of the Originator Collateral is or shall become evidenced by any
instrument, such instrument, other than checks and notes received in the
ordinary course of business, shall be duly endorsed in a manner satisfactory to
Buyer immediately upon the applicable Originator's receipt thereof and promptly
delivered to Buyer.

     THIS RECEIVABLES ASSIGNMENT (the "Receivables Assignment") is entered into

WABASH NATIONAL, L.P., a Delaware limited partnership (each an "Originator" and

     1. We refer to that certain Receivables Sale and Contribution Agreement (as

hereby made a part of this Receivables Assignment and are deemed incorporated
herein in full. Unless otherwise defined herein, capitalized terms or matters of
construction defined or established in the Sale Agreement shall be applied

     2. For good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, each Originator hereby sells, or sells and
contributes, to Buyer, without recourse, except as provided in Sections 4.02(p),
4.05, and 5.01 of the Sale Agreement, all of each Originator's right, title and
interest in, to and under all of its Receivables (including all Collections,
Records and proceeds with respect thereto) existing as of the Closing Date and
thereafter created or arising at any time until the Facility Termination Date.

     3. Subject to the terms and conditions of the Sale Agreement, each
Originator hereby covenants and agrees to sign, sell or contribute, as

executed and delivered, and to do or make, or cause to be done or made, upon
request of Buyer and at each Originator's expense, any and all agreements,
instruments, papers, deeds, acts or things, supplemental, confirmatory or
otherwise, as may be reasonably required by Buyer for the purpose of or in
connection with acquiring or more effectively vesting in Buyer or evidencing the
vesting in Buyer of the property, rights, title and interests of each Originator
sold or contributed hereunder or intended to be sold or contributed hereunder.

     4. Wherever possible, each provision of this Receivables Assignment shall
be interpreted in such a manner as to be effective and valid under applicable
law, but if any provision of this Receivables Assignment shall be prohibited by

extent of such prohibition or invalidity without

                                 WARRANTY POLICY

WARRANTY INFORMATION

Products Warranted. Wabash National, L. P. (Wabash) provides the following
WARRANTY on its Trailers and RoadRailer MarkV Trailers, which are operated in
the U.S.A. and Canada (the Product), to the first retail customer. Other
products are covered by a separate warranty previously furnished.

     Warranty. Wabash warrants to the first retail customer that any new
     trailer, including a RoadRailer trailer, will be free of defects in
     material and workmanship when properly maintained and used in normal
     service free from accident, derailment or collision. Unless specified
     otherwise, the warranty shall be for the following period.

          Container chassis and special trailers - one year Dry freight,
          refrigerated and flat trailers - five years

     Normal service means the loading, unloading, and carriage of uniformly
     distributed legal loads of non-corrosive and properly secured cargo on well
     maintained railways and public roads, with gross vehicle weights not
     exceeding the labeled gross vehicle weight rating. RoadRailer trailers
     shall not be subjected to rail buff and draft forces which exceed the
     trailer's rated capacity, nor shall the trailer be operated at a speed on
     rail exceeding the rail bogie's rated speed limit.

     Wabash does not warrant parts or accessories supplied by others. Wabash
     assigns to the customer any warranties in favor of Wabash with respect to
     any such parts or accessories which may legally be assigned by Wabash.

     This warranty does not cover:

          1.   Parts which are not defective but which may wear out and have to
               be replaced.

          2.   Alignments or adjustments which are normal maintenance items not
               caused by a defect in the trailer.

          3.   Parts which after delivery have been repaired or altered by
               anyone other than Wabash's service representatives unless, in
               Wabash's opinion, such repairs or alterations did not in any way
               contribute to the defective conditions.

          4.   Any item covered by a separate Wabash warranty.

     THIS NON-ASSIGNABLE WARRANTY IS MADE BY WABASH SOLELY TO THE FIRST RETAIL
     CUSTOMER AND SHALL BE IN

     above. All warranty remedies are subject to the following limitations.
     Customer and Wabash agree that Wabash's exclusive liability under this
     warranty or otherwise shall be the repair or replacement, at Wabash's
     option, of any defective Product. Customer must give notice of the defect
     immediately after such defect is or ought to have been discovered, and
     return the Product to Wabash or other mutually agreeable location, within
     twenty (20) days after Wabash request the return. Wabash shall have no
     liability for cargo loss, loss of use or any other incidental or
     consequential damages.
