                           SECTION 1. CREDIT FACILITY

                  Subject to the terms and conditions of, and in reliance upon
the representations and warranties made in, this Agreement and the other Loan

available to Borrowers upon a Borrower's request therefor, as follows:

                  1.1.     Loans.

                  1.1.1.   Revolving Credit Loans. Each Lender agrees, severally
         and not jointly, for so long as no Default or Event of Default exists,
         to make Revolving Credit Loans to Borrowers from time to time during
         the period from the date hereof to but not including the last day of
         the Term, as requested by Borrowers in the manner set forth in Section
         1.4 and subsection 3.1.1 hereof, up to a maximum principal amount at
         any time outstanding equal to the lesser of (i) such Lender's Revolving
         Loan Commitment minus the product of such Lender's Revolving Loan
         Percentage and the sum of the Dollar Equivalent of the LC Amount and LC
         Obligations minus the product of such Lender's Revolving Loan
         Percentage and reserves, if any and (ii) the product of (a) such
         Lender's Revolving Loan Percentage and (b) an amount equal to the sum
         of the Borrowing Base at such time minus the sum of the Dollar
         Equivalent of the LC Amount and LC Obligations minus reserves, if any.
         Agent shall have the right to establish reserves in such amounts, and
         with respect to such matters as Agent shall deem necessary or
         appropriate in its reasonable credit judgment, against the

                                       -1-

<PAGE>

         amount of Revolving Credit Loans which Borrowers may otherwise request
         under this subsection 1.1.1 including without limitation with respect
         to (i) price adjustments, damages, unearned discounts, returned
         products or other matters for which credit memoranda are issued in the
         ordinary course of a Borrower's business; (ii) potential dilution
         related to Accounts; (iii) shrinkage, spoilage and obsolescence of
         Inventory; (iv) slow moving Inventory; (v) other sums chargeable
         against a Borrower's Loan Account as Revolving Credit Loans under any
         section of this Agreement; (vi) amounts owing by a Borrower to any
         Person to the extent secured by a Lien on, or trust over, any Property
         of such Borrower, including without limitation Prior Claims; (vii)
         amounts owing by a Borrower in connection with Product Obligations and
         relating to currency exchange rate risk; (viii) the Rebuild Reserve and
         (ix) such other specific events, conditions or contingencies as to
         which Agent, in its reasonable credit judgment as is customary for
         asset based facilities of this type, determines reserves should be
         established from time to time hereunder. The reserves in place as of
         the Closing Date shall be equal to $92,500 in the aggregate.
         Notwithstanding the foregoing, Agent shall not establish any reserves
         in respect of any matters relating to any items of Collateral that have
         been taken into account in determining Eligible Inventory, Eligible
         Trailer Inventory, Eligible Bill and Hold Inventory or Eligible
         Accounts, as applicable. The Revolving Credit Loans shall be repayable
         in accordance with the terms of the Revolving Notes and as set forth in
         subsection 3.2.1, and shall be secured by, among other things, all of
         the Collateral.

                  1.1.2.   Overadvances. Insofar as a Borrower may request and
         Agent or Majority Lenders (as provided below) may be willing in their
         sole and absolute discretion to make Revolving Credit Loans to such
         Borrower at a time when the unpaid balance of Revolving Credit Loans
         plus the sum of the Dollar Equivalent of the LC Amount plus the Dollar
         Equivalent of the amount of LC Obligations that have not been
         reimbursed by Borrowers or funded with a Revolving Credit Loan, plus
         reserves, exceeds, or would exceed with the making of any such
         Revolving Credit Loan, the Borrowing Base (such Loan or Loans being
         herein referred to individually as an "Overadvance" and collectively,
         as "Overadvances"), Agent shall enter such Overadvances as debits in
         the Loan Account. All Overadvances shall be repaid on demand, shall be
         secured by the Collateral and shall bear interest as provided in this
         Agreement for Revolving Credit Loans generally. Any Overadvance made
         pursuant to the terms hereof shall be made by all Lenders ratably in
         accordance with their respective Revolving Loan Percentages.
         Overadvances in the aggregate amount of $5,000,000 or less may, unless
         a Default or Event of Default has occurred and is continuing (other
         than a Default or an Event of Default caused by the existence or making
         of such Overadvance), be made in the sole and absolute discretion of
         Agent. Overadvances in an aggregate amount of more than $5,000,000 but
         less than $7,500,000 may, unless a Default or an Event of Default has
         occurred and is continuing (other than a Default or Event of Default
         caused by the existence or making of such Overadvance), be made in the
         sole and absolute discretion of the Majority Lenders. Overadvances in
         an aggregate amount of $7,500,000 or more and Overadvances to be made
         after the occurrence and during the continuation of a

                                      -2-

<PAGE>

         Default or an Event of Default (other than a Default or Event of
         Default caused by the existence or making of such Overadvance) shall
         require the consent of all Lenders. The foregoing notwithstanding, in
         no event, unless otherwise consented to by all Lenders, (w) shall any
         Overadvances be outstanding for more than thirty (30) consecutive days,
         (x) after all outstanding Overadvances have been repaid, shall Agent or
         Lenders make any additional Overadvances unless sixty (60) days or more
         have expired since the last date on which any Overadvances were
         outstanding, (y) shall Overadvances be outstanding for more than sixty
         (60) days within any one hundred eighty day (180) period or (z) shall
         Agent make Revolving Credit Loans on behalf of Lenders under this
         subsection 1.1.2 to the extent such Revolving Credit Loans would cause
         a Lender's share of the Revolving Credit Loans to exceed such Lender's
         Revolving Loan Commitment minus such Lender's Revolving Loan Percentage
         of the sum of the Dollar Equivalent of the LC Amount and the LC
         Obligations.

                  1.1.3.   Use of Proceeds. The Revolving Credit Loans shall be
         used solely for (i) the satisfaction of existing Indebtedness of
         Borrowers, (ii) the payment of fees and expenses associated with the
         transactions contemplated hereby, (iii) Borrowers' general operating
         capital needs (including Capital Expenditures permitted hereunder) in a
         manner consistent with the provisions of this Agreement and all
         applicable laws, (iv) the funding of Permitted Acquisitions and (v)
         other purposes permitted under this Agreement.

                  1.1.4.   Swingline Loans. In order to reduce the frequency of
         transfers of funds from Lenders to Agent for making Revolving Credit
         Loans and for so long as no Default or Event of Default exists, Agent
         shall be permitted (but not required) to make Revolving Credit Loans to
         Borrowers upon request by Borrowers (such Revolving Credit Loans to be
         designated as "Swingline Loans") provided that the aggregate amount of
         Swingline Loans outstanding at any time will not (i) exceed
         $10,000,000; (ii) when added to the principal amount of Agent's other
         Revolving Credit Loans then outstanding plus Agent's Revolving Loan
         Percentage of the sum of the Dollar Equivalent of the LC Amount and the
         LC Obligations, exceed Agent's Revolving Credit Commitment; or (iii)
         when added to the principal amount of all other Revolving Credit Loans
         then outstanding plus the sum of the Dollar Equivalent of the LC Amount
         and the LC Obligations plus reserves, exceed the Borrowing Base. Within
         the foregoing limits, each Borrower may borrow, repay and reborrow
         Swingline Loans. All Swingline Loans shall be treated as Revolving
         Credit Loans for purposes of this Agreement, except that (a) all
         Swingline Loans shall be Base Rate Revolving Portions and (b)
         notwithstanding anything herein to the contrary (other than as set
         forth in the next succeeding sentence), all principal and interest paid
         with respect to Swingline Loans shall be for the sole account of Agent
         in its capacity as the lender of Swingline Loans. Notwithstanding the
         foregoing, not more than 2 Business Days after (1) Lenders receive
         notice from Agent that a Swingline Loan has been advanced in respect of
         a drawing under a Letter of Credit or LC Guaranty or (2) in any other
         circumstance, demand is made by Agent during the continuance of an
         Event

                                      -3-

<PAGE>

         of Default, each Lender shall irrevocably and unconditionally purchase
         and receive from Agent, without recourse or warranty from Agent, an
         undivided interest and participation in each Swingline Loan to the
         extent of such Lender's Revolving Loan Percentage thereof, by paying to
         Agent, in same day funds, an amount equal to such Lender's Revolving
         Loan Percentage of such Swingline Loan. Swingline Loans will be settled
         between the Agent and the Lenders in the manner set forth in subsection
         3.1.3.

                  1.1.5.   Agent Loans. Upon the occurrence and during the
         continuance of an Event of Default, Agent, in its sole discretion, may
         make Revolving Credit Loans on behalf of Lenders, in an aggregate
         amount not to exceed $5,000,000, if Agent, in its reasonable business
         judgment, deems that such Revolving Credit Loans are necessary or
         desirable (i) to protect all or any portion of the Collateral, (ii) to
         enhance the likelihood, or maximize the amount of, repayment of the
         Loans and the other Obligations, or (iii) to pay any other amount
         chargeable to any Borrower pursuant to this Agreement, including
         without limitation costs, fees and expenses as described in Sections
         2.8 and 2.9 (hereinafter, "Agent Loans"); provided, that in no event
         shall (a) the maximum principal amount of the Revolving Credit Loans
         exceed the aggregate Revolving Loan Commitments and (b) Majority
         Lenders may at any time revoke Agent's authorization to make Agent
         Loans. Any such revocation must be in writing and shall become
         effective prospectively upon Agent's receipt thereof. Each Lender shall
         be obligated to advance its Revolving Loan Percentage of each Agent
         Loan. If Agent Loans are made pursuant to the preceding sentence, then
         (a) the Borrowing Base shall be deemed increased by the amount of such
         permitted Agent Loans, but only for so long as Agent allows such Agent
         Loans to be outstanding, and (b) all Lenders that have committed to
         make Revolving Credit Loans shall be bound to make, or permit to remain
         outstanding, such Agent Loans based upon their Revolving Loan
         Percentages in accordance with the terms of this Agreement.

                  1.2.     Letters of Credit; LC Guaranties.

                  1.2.1.   Issuance of Letters of Credit and LC Guarantees.
         Agent agrees, for so long as no Default or Event of Default exists and
         if requested by a Borrower, to (i) issue its, or cause to be issued by
         Bank or another Affiliate of Agent, on the date requested by such
         Borrower, Letters of Credit (sight drafts only) for the account of a
         Borrower or (ii) execute LC Guaranties by which Agent, Bank, or another
         Affiliate of Agent, on the date requested by a Borrower, shall guaranty
         the payment or performance by a Borrower of its reimbursement
         obligations with respect to letters of credit issued for a Borrower's
         account by other Persons; provided that (a) the Dollar Equivalent of
         the LC Amount shall not exceed $15,000,000 at any time and (b) at no
         time will a Letter of Credit or LC Guaranty be issued if doing so could
         cause a violation of subsection 1.1.1. No Letter of Credit or LC
         Guaranty may have an expiration date (a) after the last day of the
         Term, (b) in the case of standby Letters of Credit or LC Guaranties
         supporting standby letters of credit, more than 1 year after the
         issuance date thereof or (c) in the case of documentary Letters of
         Credit or LC

                                      -4-

<PAGE>

         Guaranties supporting documentary letters of credit, more than 180 days
         after the issuance date hereof.

                  1.2.2.   Lender Participation. Immediately upon the issuance
         of a Letter of Credit or an LC Guaranty under this Agreement, each
         Lender shall be deemed to have irrevocably and unconditionally
         purchased and received from Agent, without recourse or warranty, an
         undivided interest and participation therein equal to the sum of the
         Dollar Equivalent of the applicable LC Amount and the applicable LC
         Obligations multiplied by such Lender's Revolving Loan Percentage.
         Agent will notify each Lender on a weekly basis, or if determined by
         Agent, a more frequent basis, upon presentation to it of a draw under a
         Letter of Credit or a demand for payment under a LC Guaranty. On a
         weekly basis, or more frequently if requested by Agent, each Lender
         shall make payment to Agent in immediately available funds in Dollars,
         of an amount equal to such Lender's pro rata share (based on such
         Lender's Revolving Loan Percentage) of the amount of any payment made
         by Agent in respect to any Letter of Credit or LC Guaranty. The
         obligation of each Lender to reimburse Agent under this subsection
         1.2.2 shall be unconditional, continuing, irrevocable and absolute,
         except in respect of indemnity claims arising out of Agent's willful
         misconduct or gross negligence. In the event that any Lender fails to
         make payment to Agent of any amount due under this subsection 1.2.2,
         Agent shall be entitled to receive, retain and apply against such
         obligation the principal and interest otherwise payable to such Lender
         hereunder until Agent receives such payment from such Lender or such
         obligation is otherwise fully satisfied; provided, however, that
         nothing contained in this sentence shall relieve such Lender of its
         obligation to reimburse the Agent for such amount in accordance with
         this subsection 1.2.2.

                  1.2.3.   Reimbursement. Notwithstanding anything to the
         contrary contained herein, Borrowers, Agent and Lenders hereby agree
         that all LC Obligations and all obligations of each Borrower relating
         thereto shall be satisfied by the prompt issuance of one or more
         Revolving Credit Loans in Dollars that are Base Rate Revolving
         Portions, which Borrowers hereby acknowledge are requested and Lenders
         hereby agree to fund. In the event that Revolving Credit Loans are not,
         for any reason, promptly made to satisfy all then existing LC
         Obligations, each Lender hereby agrees to pay to Agent, on demand, an
         amount equal to the Dollar Equivalent of such LC Obligations multiplied
         by such Lender's Revolving Loan Percentage, and until so paid, such
         amount shall be secured by the Collateral and shall bear interest and
         be payable at the same rate and in the same manner as Base Rate
         Revolving Portions. In no event shall Agent or any Lender make any
         Revolving Credit Loan in respect of any Obligation that has already
         been satisfied by any Borrower.

                  1.3.     Term Loan.

                  Each Lender, severally and not jointly, agrees to make a term
loan (collectively, the "Term Loan") to Borrowers on the Closing Date, in the
aggregate principal amount of such Lender's Term Loan Commitment, which shall be
repayable in accordance with the terms of the Term Notes and as set forth in
subsection 3.2.1, and shall be secured by, among other things, all

                                      -5-

<PAGE>

of the Collateral. The proceeds of the Term Loan shall be used solely for the
purposes for which the proceeds of the Revolving Credit Loans are authorized to
be used. The aggregate amount of the Term Loan Commitments on the Closing Date
shall be equal to $47,100,000.

                  1.4.     Borrowing Agent.

                  For ease of administration of this Agreement, each Borrower
other than Wabash hereby appoints Wabash as its borrowing agent hereunder. In
such capacity, Wabash will request all Revolving Credit Loans to be made
pursuant to Section 1.1, will request all Letters of Credit and LC Guaranties to
be issued pursuant to Section 1.2 and will submit all LIBOR Requests with
respect to obtaining any LIBOR Portion pursuant to subsection 3.1.7, converting
any Base Rate Portion into a LIBOR Portion pursuant to subsection 3.1.8 or
continuing any LIBOR Portion into a subsequent Interest Period pursuant to
subsection 3.1.9, in each case pursuant to the procedures set forth in Section
3.1. Notwithstanding anything to the contrary contained in this Agreement, no
Borrower other than Wabash shall be entitled to directly request any Revolving
Credit Loans, Letters of Credit or LC Guaranties or to submit any LIBOR Requests
hereunder and such requests shall be directed through Wabash, as borrowing agent
hereunder, for any requesting Borrower. The proceeds of all Revolving Credit
Loans made hereunder shall be advanced to or at the direction of Wabash and used
solely for the purposes described in subsection 1.1.3.

                  1.5.     Alternate Currencies.

                  After the Closing Date, Borrowers may request that Letters of
Credit and/or LC Guaranties be issued in any lawful currency other than Dollars
that is at such time freely traded in the offshore interbank foreign exchange
and foreign deposit market in which Bank customarily funds loans in currencies
other than Dollars, by means of a written request received by Agent at least 7
Business Days prior to the issuance date for the Letter of Credit or LC
Guaranty. Agent may accept or reject such request in the exercise of its sole
discretion and shall promptly inform Borrowers thereof. If Agent accepts any
such request, the currency designated shall be referred to as an "Agreed
Alternate Currency". Notwithstanding the foregoing, any otherwise Agreed
Alternate Currency shall automatically cease being an Agreed Alternate Currency
at such time that, in Agent's determination, such currency could not reasonably
be converted by Agent into Dollars within 3 Business Days. Upon any draw upon a
Letter of Credit or LC Guaranty, the amount of such draw shall be immediately
converted into Dollars in the manner provided in Section 1.6. All reserves
against Availability relating to the LC Amount or LC Obligations shall be
adjusted at a frequency determined by Agent (but no less frequently than
monthly) on the basis of a mark-to-market conversion completed in the manner set
forth in Section 1.6.

                  1.6.     Dollars; Conversion to Dollars.

                  Unless otherwise specifically set forth in this Agreement, all
monetary amounts shall be in Dollars. All valuations or computations of monetary
amounts set forth in this Agreement shall include the Dollar Equivalent of
amounts designated in Canadian Dollars or any Agreed Alternate Currency. In
connection with all Dollar amounts set forth in this

                                      -6-

<PAGE>

Agreement, all Canadian Dollars or amounts in any Agreed Alternate Currency
shall be converted to Dollars in accordance with prevailing exchange rates, as
determined by Agent in its sole discretion, on the applicable date.

                  1.7.     Judgment Currency; Contractual Currency.

                           (i)      If, for the purpose of obtaining or
                  enforcing judgment against any Borrower or Guarantor or any
                  other party to this Agreement in any court in any
                  jurisdiction, it becomes necessary to convert into any other
                  currency (such other currency being hereinafter in this
                  Section 1.7 referred to as the "Judgment Currency") an amount
                  due under any Loan Document in any currency (the "Obligation
                  Currency") other than the Judgment Currency, the conversion
                  shall be made at the rate of exchange prevailing on the
                  Business Day immediately preceding (a) the date of actual
                  payment of the amount due, in the case of any proceeding in
                  the courts of any jurisdiction that will give effect to such
                  conversion being made on such date, or (b) the date on which
                  the judgment is given, in the case of any proceeding in the
                  courts of any other jurisdiction (the applicable date as of
                  which such conversion is made pursuant to this Section 1.7
                  being hereinafter in this Section 1.7 referred to as the
                  "Judgment Conversion Date").

                           (ii)     If, in the case of any proceeding in the
                  court of any jurisdiction referred to in subsection 1.7(i),
                  there is a change in the rate of exchange prevailing between
                  the Judgment Conversion Date and the date of actual receipt
                  for value of the amount due, the applicable Borrower or
                  Guarantor shall pay such additional amount (if any, but in any
                  event not a lesser amount) as may be necessary to ensure that
                  the amount actually received in the Judgment Currency, when
                  converted at the rate of exchange prevailing on the date of
                  payment, will produce the amount of the Obligation Currency
                  which could have been purchased with the amount of the
                  Judgment Currency stipulated in the judgment or judicial order
                  at the rate of exchange prevailing on the Judgment Conversion
                  Date. Any amount due from a Borrower or Guarantor under this
                  subsection 1.7(ii) shall be due as a separate debt and shall
                  not be affected by judgment being obtained for any other
                  amounts due under or in respect of any of the Documents.

                           (iii)    The term "rate of exchange" in this Section
                  1.7 means the rate of exchange at which Agent would, on the
                  relevant date at or about 12:00 noon (Chicago time), be
                  prepared to sell the Obligation Currency against the Judgment
                  Currency.

                           (iv)     Any amount received or recovered by Agent in
                  respect of any sum expressed to be due to it (whether for
                  itself or as trustee for any other person) from any Borrower
                  or Guarantor of any other party under this Agreement or under
                  any of the other Loan Documents in a currency other than the
                  currency (the "contractual currency") in which such sum is so
                  expressed to

                                      -7-

<PAGE>

                  be due (whether as a result of or from the enforcement of, any
                  judgment or order of a court or tribunal of any jurisdiction,
                  the winding-up of a Borrower or Guarantor or otherwise) shall
                  only constitute a discharge of such Borrower or Guarantor to
                  the extent of the amount of the contractual currency that
                  Agent is able, in accordance with its usual practice, to
                  purchase with the amount of the currency so received or
                  recovered on the date of receipt or recovery (or, if later,
                  the first date on which such purchase is practicable). If the
                  amount of the contractual currency so purchased is less than
                  the amount of the contractual currency so expressed to be due,
                  such Borrower or Guarantor shall indemnify Agent against any
                  loss sustained by it as a result, including the cost of making
                  any such purchase.

                  1.8.     Common Enterprise.

                  Wabash is the direct or indirect and beneficial owner and
holder of all of the issued and outstanding shares of stock or other equity
interests in each other Borrower and Subsidiary Guarantor. Borrowers and
Subsidiary Guarantors make up a related organization of various entities
constituting a single economic and business enterprise so that Borrowers and
Subsidiary Guarantors share a substantial identity of interests such that any
benefit received by any one of them benefits the others. Borrowers and certain
of the Subsidiary Guarantors render services to or for the benefit of Borrowers
and/or the other Subsidiary Guarantors, as the case may be, purchase or sell and
supply goods to or from or for the benefit of the others, make loans, advances
and provide other financial accommodations to or for the benefit of Borrowers
and Subsidiary Guarantors (including inter alia, the payment by Borrowers and
Subsidiary Guarantors of creditors of the Borrowers or Subsidiary Guarantors and
guarantees by Borrowers and Subsidiary Guarantors of indebtedness of Borrowers
and Subsidiary Guarantors and provide administrative, marketing, payroll and
management services to or for the benefit of Borrowers and Subsidiary
Guarantors). Borrowers and Subsidiary Guarantors have centralized accounting,
common officers and directors and are in certain circumstances, identified to
creditors as a single economic and business enterprise.

                      SECTION 2. INTEREST, FEES AND CHARGES

                  2.1.     Interest.

                  2.1.1.   Rates of Interest. Interest shall accrue on the
         principal amount of the Base Rate Revolving Portions and the Base Rate
         Term Portions outstanding at the end of each day at a fluctuating rate
         per annum equal to the Applicable Margin then in effect plus the Base
         Rate. Said rate of interest shall increase or decrease by an amount
         equal to any increase or decrease in the Base Rate, effective as of the
         opening of business on the day that any such change in the Base Rate
         occurs. If a Borrower exercises its LIBOR Option as provided in Section
         3.1, interest shall accrue on the principal amount of the LIBOR
         Revolving Portions and the LIBOR Term Portions outstanding at the end
         of each day at a rate per annum equal to the Applicable Margin then in
         effect plus the LIBOR applicable to each LIBOR Portion for the
         corresponding Interest Period.

                                      -8-

<PAGE>

                  2.1.2.   Default Rate of Interest. At the option of Agent or
         the Majority Lenders, upon and after the occurrence of an Event of
         Default and during the continuation thereof, the principal amount of
         all Loans shall bear interest at a rate per annum equal to 2.0% plus
         the interest rate otherwise applicable thereto (the "Default Rate").

                  2.1.3.   Maximum Interest. In no event whatsoever shall the
         aggregate of all amounts deemed interest hereunder or under the Notes
         and charged or collected pursuant to the terms of this Agreement or
         pursuant to the Notes exceed the highest rate permissible under any law
         which a court of competent jurisdiction shall, in a final
         determination, deem applicable hereto. If any provisions of this
         Agreement or the Notes are in contravention of any such law, such
         provisions shall be deemed amended to conform thereto (the "Maximum
         Rate"). If at any time, the amount of interest paid hereunder is
         limited by the Maximum Rate, and the amount at which interest accrues
         hereunder is subsequently below the Maximum Rate, the rate at which
         interest accrues hereunder shall remain at the Maximum Rate, until such
         time as the aggregate interest paid hereunder equals the amount of
         interest that would have been paid had the Maximum Rate not applied.

                  2.2.     Computation of Interest and Fees.

                  Interest, Letter of Credit and LC Guaranty fees and Unused
Line Fees hereunder shall be calculated daily and shall be computed on the
actual number of days elapsed over a year of 360 days.

                  2.3.     Fee Letter.

                  Borrowers shall jointly and severally pay to Agent certain
fees and other amounts in accordance with the terms of the fee letter among
Borrowers and Agent (the "Fee Letter").

                  2.4.     Letter of Credit and LC Guaranty Fees.

                  Borrowers shall jointly and severally pay to Agent:

                           (i)      for standby Letters of Credit and LC

                  aggregate undrawn available amount of such Letters of Credit
                  and LC Guaranties outstanding from time to time during the

                  associated with the issuance, processing and administration

                  Letter of Credit or LC Guaranty, shall be due and payable in

                  for any reason; provided, that at any time that the Default
                  Rate is in effect, the fee applicable under this subsection
                  shall be equal to the otherwise applicable fee plus 2.00%;

                  charges shall be fully earned upon issuance, renewal or
                  extension (as the case may be) of each such Letter of Credit
                  or LC Guaranty (or as advised by Agent or Bank), shall be due
                  and payable in arrears on the first Business Day of each month
                  (or as advised by Agent or Bank), and shall not be subject to
                  rebate or proration upon the termination of this Agreement for
                  any reason); provided, that at any time that the Default Rate
                  is in effect, the fee applicable under this subsection shall
                  be equal to the otherwise applicable fee plus 2.00%; and

                           (iii)    with respect to all Letters of Credit and LC
                  Guaranties, for the account of Agent only, a per annum
                  fronting fee equal to 0.25% of the aggregate undrawn available
                  amount of such Letters of Credit and LC Guaranties outstanding
                  from time to time during the term of this Agreement, which
                  fronting fees shall be due and payable monthly in arrears on
                  the first Business Day of each month and shall not be subject
                  to rebate or proration upon the termination of this Agreement
                  for any reason.

                  2.5.     Unused Line Fee.

                  Borrowers shall jointly and severally pay to Agent, for the
ratable benefit of Lenders and Agent (as lender of the Swingline Loans), a fee
(the "Unused Line Fee") equal to the Applicable Margin per annum for the Unused
Line Fee multiplied by the average daily amount by which the Revolving Credit
Maximum Amount exceeds the sum of (i) the outstanding principal balance of the
Revolving Credit Loans and the Swingline Loans plus (ii) the sum of the Dollar
Equivalent of the LC Amount and the LC Obligations; provided, that for purposes
of allocating the Unused Line Fee among Lenders (other than Agent), outstanding
Swingline Loans shall not be included as part of the outstanding balance of the
Loans for purposes of calculating such fees owed to Lenders other than Agent.
The Unused Line Fee shall be payable monthly in arrears on the first day of each
month hereafter.

                  2.6.     Intentionally omitted.

                  2.7.     Audit Fees.

                  Borrowers shall jointly and severally pay to Agent
commercially reasonable audit fees in accordance with Agent's current schedule
of fees in effect from time to time in connection with audits of the books and
records and Properties of each Borrower and its Subsidiaries and such other
matters as Agent shall deem appropriate in its reasonable credit judgment, plus
all reasonable out-of-pocket expenses incurred by Agent in connection with such
audits, whether such audits are conducted by employees of Agent or by third
parties hired by Agent. Such audit fees and out-of-pocket expenses shall be
payable on the first day of the month following the date of issuance by Agent of
a request for payment thereof to Wabash. Agent may, in its discretion, provide
for the payment of such amounts by making appropriate Revolving Credit Loans to
one or more Borrowers and charging the appropriate Loan Account or Loan Accounts
therefor. So long as no Event of Default is in existence, such audit fees shall
not exceed $75,000 in the aggregate in any calendar year.

                  2.8.     Reimbursement of Expenses.

                  If, at any time or times regardless of whether or not an Event
of Default then exists, (i) Agent or Arranger incurs reasonable legal or
accounting expenses or any other costs or out-of-pocket expenses in connection
with (1) the negotiation and preparation of this Agreement or any of the other
Loan Documents, any amendment of or modification of this Agreement or any of the
other Loan Documents, or any syndication or attempted syndication of the
Obligations (including, without limitation, printing and distribution of
materials to prospective Lenders and all costs associated with bank meetings,
but excluding any closing fees paid to Lenders in connection therewith) or (2)
the administration of this Agreement or any of the other Loan Documents and the
transactions contemplated hereby and thereby; or (ii) Agent or any Lender incurs
reasonable legal or accounting expenses or any other costs or out-of-pocket
expenses in connection with (1) any litigation, contest, dispute, suit,
proceeding or action (whether instituted by Agent, any Lender, any Borrower or
any other Person) relating to the Collateral, this Agreement or any of the other
Loan Documents or any Borrower's, any Subsidiary's or any Guarantor's affairs;
(2) any amendment, modification, waiver or consent with respect to the Loan
Documents requested of any Lender at a time when an Event of Default is in
existence; (3) any attempt to enforce any rights of Agent or any Lender against
any Borrower or any other Person which may be obligated to Agent or any Lender
by virtue of this Agreement or any of the other Loan Documents, including,
without limitation, the Account Debtors; or (4) any attempt to inspect, verify,
protect, preserve, restore, collect, sell, liquidate or otherwise dispose of or
realize upon the Collateral; then all such reasonable legal and accounting
expenses, other costs and out of pocket expenses of Agent or any Lender, as
applicable, shall be charged to Borrowers on a joint and several basis;
provided, that Borrowers shall not be responsible for such expenses, costs and
out-of-pocket expenses to the extent incurred because of the gross negligence or
willful misconduct of Agent or any Lender. All amounts chargeable to Borrowers
under this Section 2.8 shall be Obligations secured by all of the Collateral,
shall be payable on demand to Agent or such Lender, as the case may be, and
shall bear interest from the date such demand is made until paid in full at the
rate applicable to Base Rate Revolving Portions from time to time. Borrowers
shall also jointly and severally

                                      -11-

<PAGE>

reimburse Agent and Lenders for expenses incurred by Agent in its administration
of the Collateral to the extent and in the manner provided in Sections 2.9 and
2.10 hereof.

                  2.9.     Bank Charges.

                  Borrowers shall jointly and severally pay to Agent and each
applicable Lender, on demand, any and all fees, costs or expenses which Agent or
such Lender pays to a bank or other similar institution arising out of or in
connection with (i) the forwarding to any Borrower or any other Person on behalf
of any Borrower, by Agent or any Lender, of proceeds of Loans made to any
Borrower pursuant to this Agreement and (ii) the depositing for collection by
Agent or any Lender of any check or item of payment received or delivered to
Agent or any Lender on account of the Obligations.

                  2.10.    Collateral Protection Expenses; Appraisals.

                  All commercially reasonable out-of-pocket expenses incurred in
protecting, storing, warehousing, insuring, handling, maintaining and shipping
the Collateral, and any and all excise, property, sales, and use taxes imposed
by any state, federal, or local authority on any of the Collateral or in respect
of the sale thereof shall be jointly and severally borne and paid by Borrowers.
If Borrowers fail to promptly pay any portion thereof when due, Agent may, at
its option, but shall not be required to, pay the same and charge one or more
Borrowers therefor. On an annual basis, at Borrowers' joint and several expense,
Agent shall (i) obtain a desk top appraisal of the Inventory, the Bill and Hold
Inventory and the Trailer Inventory of the Companies conducted by an employee of
Agent or a third party appraiser reasonably acceptable to Agent and (ii) obtain
an appraisal of the Inventory, the Bill and Hold Inventory and the Trailer
Inventory of the Companies from a third party appraiser reasonably acceptable to
Agent, each of which appraisals shall include an assessment of the net orderly
liquidation percentage of each category or type of Inventory, Bill and Hold
Inventory and Trailer Inventory. Additionally, from time to time, if Agent or
any Lender determines that obtaining appraisals is necessary in order for it to
comply with applicable laws or regulations, and at any time if a Default or an
Event of Default shall have occurred and be continuing, Agent may, and at the
direction of the applicable Lender, Agent shall, at Borrowers' joint and several
expense, obtain appraisals from appraisers (who may be personnel of Agent),
stating the then current fair market value of all or any portion of the real
Property or personal Property of any Company, including without limitation the
Inventory of any Company.

                  2.11.    Payment of Charges.

                  All amounts chargeable to any Borrower under this Agreement
shall be Obligations secured by all of the Collateral, shall be, unless
specifically otherwise provided, payable on demand and shall bear interest from
the date demand was made or such amount is due, as applicable, until paid in
full at the rate applicable to Base Rate Revolving Portions from time to time.

                                      -12-

<PAGE>

                  2.12.    No Deductions.

                  Any and all payments or reimbursements made hereunder shall be
made free and clear of and without deduction for any and all taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto; excluding, however, the following: taxes imposed on the income of Agent
or any Lender or franchise taxes by the jurisdiction under the laws of which
Agent or any Lender is organized or doing business or any political subdivision
thereof and taxes imposed on its income by the jurisdiction of Agent's or such
Lender's applicable lending office or any political subdivision thereof or
franchise taxes (all such taxes, levies, imposts, deductions, charges or
withholdings and all liabilities with respect thereto excluding such taxes
imposed on net income, herein "Tax Liabilities"). If any Borrower shall be
required by law to deduct any such Tax Liabilities from or in respect of any sum
payable hereunder to Agent or any Lender, then the sum payable hereunder by
Borrowers shall be increased as may be necessary so that, after all required
deductions are made, Agent or such Lender receives an amount equal to the sum it
would have received had no such deductions been made.

                  2.13.    Joint and Several Obligations.

                  Each Borrower acknowledges that it is jointly and severally
liable for all of the Obligations and as a result hereby unconditionally
guaranties the full and prompt payment when due, whether at maturity or earlier,
by reason of acceleration or otherwise, and at all times thereafter, of all
indebtedness, liabilities and obligations of every kind and nature of each other
Borrower to Agent and Lenders and, howsoever created, arising or evidenced,
whether direct or indirect, absolute or contingent, joint or several, now or
hereafter existing, or due or to become due, and howsoever owned, held or
acquired by Agent or any Lender. Each Borrower agrees that if this guaranty, or
any Liens securing this guaranty, would, but for the application of this
sentence, be unenforceable under applicable law, this guaranty and each such
Lien shall be valid and enforceable to the maximum extent that would not cause
this guaranty or such Lien to be unenforceable under applicable law, and this
guaranty shall automatically be deemed to have been amended accordingly at all
relevant times.

                  Each Borrower hereby agrees that its obligations under this
guaranty shall be unconditional, irrespective of (a) the validity or
enforceability of the Obligations or any part thereof, or of any promissory note
or other document evidencing all or any part of the Obligations, (b) the absence
of any attempt to collect the Obligations from any other Borrower or any
Guarantor or other action to enforce the same, (c) the waiver or consent by
Agent or any Lender with respect to any provision of any agreement, instrument
or document evidencing or securing all or any part of the Obligations, or any
other agreement, instrument or document now or hereafter executed by any other
Borrower and delivered to Agent or any Lender (other than a waiver, forgiveness
or consent by Agent and Lenders that reduces the amount of any of the
Obligations), (d) the failure by Agent or any Lender to take any steps to
perfect and maintain its security interest in, or to preserve its rights to, any
security or Collateral for the Obligations, for its benefit, (e) Agent's or any
Lender's election, in any proceeding instituted under the United States
Bankruptcy Code or any other similar bankruptcy or insolvency legislation, of
the application of Section 1111(b)(2) of the United States Bankruptcy Code or
any other similar

                                      -13-

<PAGE>

bankruptcy or insolvency legislation, (f) any borrowing or grant of a security
interest by any Borrower as debtor-in-possession, under Section 364 of the
United States Bankruptcy Code or any other similar bankruptcy or insolvency
legislation, (g) the disallowance, under Section 502 of the United States
Bankruptcy Code or any other similar bankruptcy or insolvency legislation, of
all or any portion of Agent's or any Lender's claim(s) for repayment of the
Obligations or (h) any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a borrower or a guarantor.

                  Each Borrower hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of receivership or
bankruptcy of any Borrower, protest or notice with respect to the Obligations
and all demands whatsoever, and covenants that this guaranty will not be
discharged, except by complete and irrevocable payment and performance of the
Obligations. No notice to any Borrower or any other party shall be required for
Agent or any Lender to make demand hereunder. Such demand shall constitute a
mature and liquidated claim against the applicable Borrower. Upon the occurrence
of any Event of Default, Agent or any Lender may, in its sole election, proceed
directly and at once, without notice, against all or any Borrower to collect and
recover the full amount or any portion of the Obligations, without first
proceeding against any other Borrower or any other Person, or any security or
collateral for the Obligations. During the existence of an Event of Default,
Agent and each Lender shall have the exclusive right to determine the
application of payments and credits, if any from any Borrower, any other Person
or any security or collateral for the Obligations, on account of the Obligations
or of any other liability of any Borrower to Agent or any Lender.

                  At any time after and during the continuance of an Event of
Default, Agent and each Lender may, in its sole discretion, without notice to
any Borrower and regardless of the acceptance of any collateral for the payment
hereof, appropriate and apply toward payment of the Obligations (i) any
indebtedness due or to become due from Agent or any Lender to such Borrower and
(ii) any moneys, credits or other property belonging to such Borrower at any
time held by or coming into the possession of Agent or any Lender or any
Affiliates thereof, whether for deposit or otherwise.

                  Notwithstanding anything to the contrary set forth in this
Section 2.13, it is the intent of the parties hereto that the liability incurred
by each Borrower in respect of the Obligations of the other Borrowers (and any
Lien granted by each Borrower to secure such Obligations), not constitute a
fraudulent conveyance under Section 548 of the United States Bankruptcy Code or
a fraudulent conveyance or fraudulent transfer under the provisions of any
applicable law of any state or other governmental unit ("Fraudulent
Conveyance"). Consequently, each Borrower, Agent and each Lender hereby agree
that if a court of competent jurisdiction determines that the incurrence of
liability by any Borrower in respect of the Obligations of any other Borrower
(or any Liens granted by such Borrower to secure such Obligations) would, but
for the application of this sentence, constitute a Fraudulent Conveyance, such
liability (and such Liens) shall be valid and enforceable only to the maximum
extent that would not cause the same to constitute a Fraudulent Conveyance, and
this Agreement and the other Loan Documents shall automatically be deemed to
have been amended accordingly.

                                      -14-

<PAGE>

                  Each Borrower expressly waives all rights it may have now or
in the future under any statute, or at common law, or at law or in equity, or
otherwise, to compel Agent or Lenders to marshall assets or to proceed in
respect of the Obligations guaranteed hereunder against any other Borrower or
any Guarantor, any other party or against any security for the payment and
performance of the Obligations before proceeding against, or as a condition to
proceeding against, such Borrower. It is agreed among each Borrower, Agent and
Lenders that the foregoing waivers are of the essence of the transaction
contemplated by this Agreement and the other Loan Documents and that, but for
the provisions of this Section 2.13 and such waivers, Agent and Lenders would
decline to enter into this Agreement.

                  Each Borrower agrees that the provisions of this Section 2.13
are for the benefit of Agent and Lenders and their respective successors,
transferees, endorsees and assigns, and nothing herein contained shall impair,
as between any other Borrower and Agent or Lenders, the obligations of such
other Borrower under the Loan Documents.

                  Notwithstanding anything to the contrary in this Agreement or
in any other Loan Document, and except as set forth in Section 2.13, each
Borrower hereby expressly and irrevocably subordinates to payment of the
Obligations any and all rights at law or in equity to subrogation,
reimbursement, exoneration, contribution, indemnification or set off (including
those set forth in Section 2.14) and any and all defenses available to a surety,
guarantor or accommodation co-obligor until the Obligations are indefeasibly
paid in full in cash. Each Borrower acknowledges and agrees that this
subordination is intended to benefit Agent and Lenders and shall not limit or
otherwise affect such Borrower's liability hereunder or the enforceability of
this Section 2.13, and that Agent, Lenders and their respective successors and
assigns are intended third party beneficiaries of the waivers and agreements set
forth in this Section 2.13.

                  If Agent or any Lender may, under applicable law, proceed to
realize its benefits under any of the Loan Documents giving Agent or such Lender
a Lien upon any Collateral, whether owned by any Borrower or by any other
Person, either by judicial foreclosure or by non-judicial sale or enforcement,
Agent or any Lender may, at its sole option, determine which of its remedies or
rights it may pursue without affecting any of its rights and remedies under this
Section 2.13. If, in the exercise of any of its rights and remedies, Agent or
any Lender shall forfeit any of its rights or remedies, including its right to
enter a deficiency judgment against any Borrower or any other Person, whether
because of any applicable laws pertaining to "election of remedies" or the like,
each Borrower hereby consents to such action by Agent or such Lender and waives
any claim based upon such action, even if such action by Agent or such Lender
shall result in a full or partial loss of any rights of subrogation that each
Borrower might otherwise have had but for such action by Agent or such Lender.
Any election of remedies that results in the denial or impairment of the right
of Agent or any Lender to seek a deficiency judgment against any Borrower shall
not impair any other Borrower's obligation to pay the full amount of the
Obligations. In the event Agent or any Lender shall bid at any foreclosure or
trustee's sale or at any private sale permitted by law or the Loan Documents,
Agent or such Lender may bid all or less than the amount of the Obligations and
the amount of such bid need not be paid by Agent or such Lender but shall be
credited against the Obligations. The amount of the successful bid at any such
sale, whether Agent, Lender or any other party is the

                                      -15-

<PAGE>

successful bidder, shall be conclusively deemed to be the fair market value of
the Collateral and the difference between such bid amount and the remaining
balance of the Obligations shall be conclusively deemed to be the amount of the
Obligations guaranteed under this Section 2.13, notwithstanding that any present
or future law or court decision or ruling may have the effect of reducing the
amount of any deficiency claim to which Agent or any Lender might otherwise be
entitled but for such bidding at any such sale.

                  The liability of Borrowers under this Section 2.13 is in
addition to and shall be cumulative with all liabilities of each Borrower to
Agent and Lenders under this Agreement and the other Loan Documents to which
such Borrower is a party or in respect of any Obligations or obligation of the
other Borrower, without any limitation as to amount, unless the instrument or
agreement evidencing or creating such other liability specifically provides to
the contrary.

                  2.14.    Subrogation and Contribution.

                  Each Borrower agrees that if any other Borrower or any
Guarantor makes a payment in respect of the Obligations, subject to Section
2.13, it shall be subrogated to the rights of the payees thereof against the
other Borrowers and Guarantors with respect to such payment and shall have the
rights of contribution set forth below against the other Borrowers and
Guarantors. Subject to Section 2.13, each Borrower or Guarantor shall make
payments in respect of the Obligations or contribution payments to the other
Borrowers and Guarantors such that, taking into account all payments received on
account of subrogation or contribution rights: (a) each Borrower or Guarantor
shall have repaid at some time after the date hereof all Obligations the benefit
of which have been received by it or, if the aggregate of all such repayments
would exceed the outstanding Obligations, its pro rata share of the outstanding
Obligations, in accordance with the benefit received by it and (b) if there
remain Obligations unpaid after application of the payments referred to above,
the deficiency shall be shared by Borrowers and Guarantors pro rata in
preparation to their respective net worths on the Closing Date.

                         SECTION 3. LOAN ADMINISTRATION.

                  3.1.     Manner of Borrowing Revolving Credit Loans/LIBOR
                           Option.

                  Borrowings under the credit facility established pursuant to
Section 1 hereof shall be as follows:

                  3.1.1.   Loan Requests. A request for a Revolving Credit Loan
         shall be made, or shall be deemed to be made, in the following manner:
         (a) subject to the terms of Section 1.4, Wabash (on behalf of
         Borrowers) may give Agent notice of its intention to borrow, in which
         notice Wabash shall specify the amount of the proposed borrowing of a
         Revolving Credit Loan (which shall be no less than $500,000 or an
         integral multiple of $100,000) and the proposed borrowing date, which
         shall be a Business Day, no later than 11:00 a.m. (Chicago, Illinois
         time) on the proposed borrowing date (or in accordance with subsection
         3.1.7, 3.1.8 or 3.1.9, as applicable, in the case of a request for a
         LIBOR Revolving Portion), provided, however, that no

                                      -16-

<PAGE>

         such request may be made at a time when there exists a Default or an
         Event of Default; and (b) the becoming due of any amount required to be
         paid under this Agreement, or the Notes, whether as interest or for any
         other Obligation, shall be deemed irrevocably to be a request by a
         Borrower for a Revolving Credit Loan on the due date in the amount
         required to pay such interest or other Obligation.

                  3.1.2.   Disbursement. Each Borrower hereby irrevocably
         authorizes Agent to disburse the proceeds of each Loan requested, or
         deemed to be requested, pursuant to subsection 3.1.1 as follows: (i)
         the proceeds of each Revolving Credit Loan requested under subsection
         3.1.1(a) shall be disbursed by Agent in lawful money of the United
         States of America in immediately available funds, in the case of the
         initial borrowing, in accordance with the terms of the written
         disbursement letter from Borrowers, and in the case of each subsequent
         borrowing, by wire transfer to such bank account as may be agreed upon
         by Borrowers and Agent from time to time or elsewhere if pursuant to a
         written direction from a Borrower and (ii) the proceeds of each
         Revolving Credit Loan deemed requested under subsection 3.1.1(b) shall
         be disbursed by Agent by way of direct payment of the relevant interest
         or other Obligation. If at any time any Loan is funded by Agent or
         Lenders in excess of the amount requested or deemed requested by a
         Borrower, such Borrower agrees to repay the excess to Agent immediately
         upon the earlier to occur of (a) such Borrower's discovery of the error
         and (b) notice thereof to such Borrower from Agent or any Lender.

                  3.1.3.   Payment by Lenders. Agent shall give to each Lender
         prompt written notice by facsimile, telex or cable of the receipt by
         Agent from Wabash of any request for a Revolving Credit Loan. Each such
         notice shall specify the requested date and amount of such Revolving
         Credit Loan, whether such Revolving Credit Loan shall be subject to the
         LIBOR Option, and the amount of each Lender's advance thereunder (in
         accordance with its applicable Revolving Loan Percentage). Each Lender
         shall, not later than 12:00 p.m. (Chicago time) on such requested date,
         wire to a bank designated by Agent the amount of that Lender's
         Revolving Loan Percentage of the requested Revolving Credit Loan. The
         failure of any Lender to make the Revolving Credit Loans to be made by
         it shall not release any other Lender of its obligations hereunder to
         make its Revolving Credit Loan. Neither Agent nor any other Lender
         shall be responsible for the failure of any other Lender to make the
         Revolving Credit Loan to be made by such other Lender. The foregoing
         notwithstanding, Agent, in its sole discretion, may from its own funds
         make a Revolving Credit Loan on behalf of any Lender. In such event,
         the Lender on behalf of whom Agent made the Revolving Credit Loan shall
         reimburse Agent for the amount of such Revolving Credit Loan made on
         its behalf, on a weekly (or more frequent, as determined by Agent in
         its sole discretion) basis. In addition, Agent shall notify Lenders on
         a weekly (or more frequent, as determined by Agent in its sole
         discretion) basis regarding settlement of the Swingline Loans, and
         promptly following such notice, each Lender shall reimburse Agent (in
         accordance with its applicable Revolving Loan Percentage) for the
         amount of the Swingline Loans outstanding. On each such settlement
         date, Agent will pay to each Lender the net amount owing to such Lender
         in connection with such

                                      -17-

<PAGE>

         settlement, including without limitation amounts relating to Loans,
         fees, interest and other amounts payable hereunder. The entire amount
         of interest attributable to such Revolving Credit Loan or Swingline
         Loan for the period from the date on which such Revolving Credit Loan
         or Swingline Loan was made by Agent on such Lender's behalf until Agent
         is reimbursed by such Lender, shall be paid to Agent for its own
         account.

                  3.1.4.   Authorization. Each Borrower hereby irrevocably
         authorizes Agent, in Agent's sole discretion, to advance to Wabash or
         another Borrower, and to charge to the appropriate Borrower's Loan
         Account hereunder as a Revolving Credit Loan (which shall be a Base
         Rate Revolving Portion), a sum sufficient to pay all interest accrued
         on the Obligations during the immediately preceding month, to pay all
         principal due and payable at any time and to pay all fees, costs and
         expenses and other Obligations at any time owed by each Borrower to
         Agent or any Lender hereunder.

                  3.1.5.   Letter of Credit and LC Guaranty Requests. A request
         for a Letter of Credit or LC Guaranty shall be made in the following
         manner: Wabash (on behalf of Borrowers) shall give Agent and Bank a
         written notice of its request for the issuance of a Letter of Credit or
         LC Guaranty, not later than 11:00 a.m. (Chicago, Illinois time), at
         least one Business Day before the proposed issuance date thereof, in
         which notice such Borrower shall specify the proposed issuer, issuance
         date and format and wording for the Letter of Credit or LC Guaranty
         being requested (which shall be satisfactory to Agent and the Person
         being asked to issue such Letter of Credit or LC Guaranty); provided,
         that no such request may be made at a time when there exists a Default
         or Event of Default. Such request shall be accompanied by an executed
         application and reimbursement agreement in form and substance
         satisfactory to Agent and the Person being asked to issue the Letter of
         Credit or LC Guaranty, as well as any required corporate resolutions or
         other documents reasonably requested by Agent or Bank.

                  3.1.6.   Method of Making Requests. As an accommodation to
         Borrowers, unless a Default or an Event of Default is then in
         existence, (i) Agent shall permit telephonic or electronic requests for
         Revolving Credit Loans to Agent, (ii) Agent and Bank may, in their
         discretion, permit electronic transmittal of requests for Letters of
         Credit and LC Guaranties to them, and (iii) Agent may, in Agent's
         discretion, permit electronic transmittal of instructions,
         authorizations, agreements or reports to Agent. Unless a Borrower
         specifically directs Agent or Bank, as applicable in writing not to
         accept or act upon telephonic or electronic communications from such
         Borrower (which direction shall only be applicable to the Persons who
         have received the same in writing), neither Agent, Bank nor any Lender
         shall have any liability to any Borrower for any loss or damage
         suffered by any Borrower as a result of Agent's or Bank's honoring of
         any requests, execution of any instructions, authorizations or
         agreements or reliance on any reports communicated to it telephonically
         or electronically and purporting to have been sent to Agent or Bank by
         any Borrower, and neither Agent or Bank shall have any duty to verify
         the origin of any such

                                      -18-

<PAGE>

         communication or the authority of the Person sending it. Each
         telephonic request for a Letter of Credit or LC Guaranty accepted by
         Agent or Bank hereunder shall be promptly followed by a written
         confirmation of such request from the applicable Borrower to Agent and
         Bank.

                  3.1.7.   LIBOR Portions. Provided that as of both the date of
         the LIBOR Request and the first day of the Interest Period, no Default
         or Event of Default exists, in the event a Borrower desires to obtain a
         LIBOR Portion, Wabash (on behalf of such Borrower) shall give Agent a
         LIBOR Request no later than 11:00 a.m. (Chicago, Illinois time) on the
         third Business Day prior to the requested borrowing date. Each LIBOR
         Request shall be irrevocable and binding on Borrowers. In no event
         shall Borrowers be permitted to have outstanding at any one time LIBOR
         Portions with more than six (6) different Interest Periods.

                  3.1.8.   Conversion of Base Rate Portions. Provided that as of
         both the date of the LIBOR Request and the first day of the Interest
         Period, no Default or Event of Default exists, a Borrower may, on any
         Business Day, convert any Base Rate Portion of such Borrower into a
         LIBOR Portion. If a Borrower desires to convert a Base Rate Portion,
         Wabash (on behalf of such Borrower) shall give Agent a LIBOR Request no
         later then 11:00 a.m. (Chicago, Illinois time) on the third Business
         Day prior to the requested conversion date. After giving effect to any
         conversion of Base Rate Portions to LIBOR Portions, Borrowers shall not
         be permitted to have outstanding at any one time LIBOR Portions with
         more than six (6) different Interest Periods.

                  3.1.9.   Continuation of LIBOR Portions. Provided that as of
         both the date of the LIBOR Request and the first day of the Interest
         Period, no Default or Event of Default exists, a Borrower may, on any
         Business Day, continue any LIBOR Portions of such Borrower into a
         subsequent Interest Period of the same or a different permitted
         duration. If a Borrower desires to continue a LIBOR Portion, Wabash (on
         behalf of such Borrower) shall give Agent a LIBOR Request no later than
         11:00 a.m. (Chicago, Illinois time) on the second Business Day prior to
         the requested continuation date. After giving effect to any
         continuation of LIBOR Portions, Borrowers shall not be permitted to
         have outstanding at any one time LIBOR Portions with more than six (6)
         different Interest Periods. If a Borrower shall fail to give timely
         notice of its election to continue any LIBOR Portion or portion thereof
         as provided above, or if such continuation shall not be permitted, such
         LIBOR Portion or portion thereof, unless such LIBOR Portion shall be
         repaid, shall automatically be converted into a Base Rate Portion at
         the end of the Interest Period then in effect with respect to such
         LIBOR Portion.

                  3.1.10.  Inability to Make LIBOR Portions. Notwithstanding any
         other provision hereof, if any applicable law, treaty, regulation or
         directive, or any change therein or in the interpretation or
         application thereof, shall make it unlawful for any Lender (for
         purposes of this subsection 3.1.10, the term "Lender" shall include the
         office or branch where such Lender or any corporation or bank then
         controlling such Lender makes or maintains any LIBOR Portions) to make
         or maintain its LIBOR

                                      -19-

<PAGE>

         Portions, or if with respect to any Interest Period, Agent is unable to
         determine the LIBOR relating thereto, or adverse or unusual conditions
         in, or changes in applicable law relating to, the London interbank
         market make it, in the reasonable judgment of Agent, impracticable to
         fund therein any of the LIBOR Portions, or make the projected LIBOR
         unreflective of the actual costs of funds therefor to any Lender, the
         obligation of Agent and Lenders to make or continue LIBOR Portions or
         convert Base Rate Portions to LIBOR Portions hereunder shall forthwith
         be suspended during the pendency of such circumstances and the
         applicable Borrower shall, if any affected LIBOR Portions are then
         outstanding, promptly upon request from Agent, convert such affected
         LIBOR Portions into Base Rate Portions.

                  3.2.     Payments.

                  Except where evidenced by Notes issued by one or more
Borrowers to any Lender and accepted by such Lender specifically containing
payment instructions that are in conflict with this Section 3.2 (in which case
the conflicting provisions of said notes or other instruments shall govern and
control), the Obligations shall be payable as follows:

                  3.2.1.   Principal.

                           (i)      Revolving Credit Loans. Principal on account

                  receipt by Agent, any Company or any Guarantor of any proceeds
                  of any of the Collateral (except as otherwise provided
                  herein), including without limitation pursuant to subsections
                  3.3.1 and 6.2.4, to the extent of said proceeds, subject to
                  Borrowers' rights to reborrow such amounts in compliance with
                  subsection 1.1.1 hereof; (ii) the occurrence of an Event of
                  Default in consequence of which Agent or Majority Lenders
                  elect to accelerate the maturity and payment of the
                  Obligations, (iii) subject to the provisions of subsection
                  1.1.2, at all times that the calculations set forth in
                  subsection 1.1.1 reflect a negative amount, to the extent of
                  such amount, or (iv) termination of this Agreement pursuant to
                  Section 4 hereof; provided, however, that, if an Overadvance
                  shall exist at any time, Borrowers shall, on demand, jointly
                  and severally repay the Overadvance. Each payment (including
                  principal prepayment) on account of principal of the Revolving
                  Credit Loans shall be applied first to Base Rate Revolving
                  Portions and then to LIBOR Revolving Portions.

                           (ii)     Term Loan. Principal on account of the Term
                  Loan shall be payable jointly and severally by Borrowers as

                  Notwithstanding the foregoing, the entire unpaid

                  in consequence of which Agent or Majority Lenders elect to
                  accelerate the maturity and payment of the Obligations or (3)
                  termination of this Agreement pursuant to Section 4 hereof.

                  LIBOR Portion shall be due and payable on each LIBOR Interest
                  Payment Date and on the earlier of (1) the occurrence of an
                  Event of Default in consequence of which Agent or Majority
                  Lenders elect to accelerate the maturity and payment of the
                  Obligations or (2) termination of this Agreement pursuant to
                  Section 4 hereof.

                  3.2.5.   Prepayment of/Failure to Borrow LIBOR Portions.
         Borrowers may prepay a LIBOR Portion only upon at least three (3)

         the conversion of any LIBOR Portion other than on the last day of the
         Interest Period applicable thereto, or (iii) the failure to borrow,

         loss, cost and expense attributable to such event, as determined by
         such Lender in a manner consistent with its customs and practices.

         in accordance with this Agreement of assets that are subject to a Lien
         permitted by subsection 8.2.5(iv) (in each case, the proceeds of which
         shall be applied to reduce the outstanding principal balance of the
         Revolving Credit Loans, but shall not permanently reduce the Revolving
         Loan Commitments), (b) as otherwise provided in subsection 8.2.9(vi)
         and (c) proceeds of Collateral received during the existence of a Event
         of Default (which shall be applied as set forth in subsection 3.4.2),
         if any Company or any Guarantor sells any of the Collateral or if any
         of the Collateral is lost, damaged or destroyed or taken by
         condemnation, the applicable Company or Guarantor shall, unless
         otherwise agreed by Majority Lenders, pay to Agent for the ratable
         benefit of Lenders as and when received by such Company or Guarantor
         and as a mandatory prepayment of the Loans, as herein provided, a sum
         equal to the proceeds (including insurance payments but net of costs
         and taxes incurred in connection with such sale or event) received by
         such Company or Guarantor from such sale, loss, damage, destruction or
         condemnation.

                  To the extent that the Collateral sold, lost, damaged,
         destroyed or condemned consists of Equipment, real Property, or other
         Property other than Accounts or Inventory, the applicable prepayment
         shall be applied first, to Agent's costs and expenses relating to the
         relevant transaction, second, to the installments of principal due
         under the Term Notes ratably, to be applied to future installment
         payments in the inverse order of maturity until paid in full and third,
         to repay outstanding principal of Revolving Credit Loans, but not as a
         permanent reduction of the Revolving Loan Commitments; provided, that

         WNTC located at 2727 South East Avenue, Fresno, California 93725; or
         the real Property of WNTC located at 9426 8th Avenue, Seattle,
         Washington, such proceeds shall be applied first, to Agent's costs and
         expenses relating to the relevant transaction, second, 50% of the
         remaining amount to the installments of principal due under the Term
         Notes ratably, to be applied to future installment payments in the
         inverse order of maturity until paid in full, and third, to repay
         outstanding principal of Revolving Credit Loans, but not as a permanent
         reduction of the Revolving Loan Commitments and (ii) any Subject
         Equipment, such proceeds shall be applied first, to repayment of the
         Other Indebtedness secured by such Subject Equipment and second, in the
         manner set forth in the first clause of this sentence.

                  To the extent that the Collateral sold, lost, damaged,
         destroyed or condemned consists of Accounts or Inventory, the
         applicable prepayment shall be applied to reduce the outstanding
         principal balance of the Revolving Credit Loans, but shall not
         permanently reduce the Revolving Loan Commitments. In addition, if the
         Collateral subject to such sale, loss, damage, destruction or
         condemnation consists of Eligible Accounts, Eligible Inventory,
         Eligible Bill and Hold Inventory or Eligible Trailer Inventory, such
         prepayment shall be specifically applied against any limits or
         sublimits contained in the Borrowing Base that are predicated on such
         Collateral.

                  Notwithstanding the foregoing, if the proceeds of insurance
         (net of costs and taxes incurred) with respect to any loss or
         destruction of Equipment or real Property,

         the then current fiscal year of Borrowers, (i) are less than
         $2,500,000, unless an Event of Default is then in existence, Agent
         shall remit such proceeds to the applicable Company or Guarantor for
         use in replacing or repairing the applicable Property, so long as the
         applicable Company or Guarantor has committed to acquire replacement
         Property within 180 days of such loss, damage or destruction and has
         actually acquired replacement Property within such 360 days of such
         loss, damage or destruction (free and clear of Liens other than
         Permitted Liens that are not Purchase Money Liens) (and if the
         applicable Company or Guarantor fails to commit to replace or rebuild
         the damaged Property within such 180 day period or fails to actually
         replace or rebuild such damaged Property within such 360 day period,
         Borrowers shall prepay the Obligations in the manner specified in the
         second sentence of this subsection 3.3.1), (ii) are greater than or
         equal to $2,500,000 and less than $5,000,000, unless an Event of
         Default is then in existence, such amounts shall be provisionally
         applied to reduce the outstanding principal balance of the Revolving
         Credit Loans (and a Rebuild Reserve shall be created in the amount of
         such proceeds), until the earliest of (1) Borrowers' decision not to
         repair or replace the damaged Property, (2) the expiration of one
         hundred eighty days (180) days from the receipt of such amount, if the
         applicable Company or Guarantor has not yet committed to acquire

         (360) days from the receipt of such amount (with such amount being
         applied to the Obligations in the manner specified in the second
         sentence of this subsection 3.3.1 until payment thereof in full in the
         event that the foregoing period ends pursuant to clause (1) or clause
         (2)), or (iii) are equal to or greater than $5,000,000, and Borrowers
         have requested that Agent and all Lenders agree to permit the
         applicable Company or Guarantor to repair or replace the damaged
         Property, such amounts shall be provisionally applied to reduce the
         outstanding principal balance of the Revolving Credit Loans (and a
         Rebuild Reserve shall be created in the amount of such proceeds), until
         the earliest of (1) Agent's and all Lenders' decision with respect
         thereto, (2) the expiration of one hundred eighty (180) days from the
         date of such request, unless the applicable Company or Guarantor has

         Borrowers decide and commit to repair or replace the applicable
         Property as provided in clause (ii) above or if Agent and all Lenders
         agree, in their reasonable judgment, to permit any such repair or
         replacement under clause (iii) above, the applicable amount shall,
         unless an Event of Default is in existence, be released from the
         Rebuild Reserve to the applicable Company or Guarantor as needed for
         use in replacing or repairing the damaged Property during such three
         hundred sixty (360) day period, with any remaining amount at the end of
         such three hundred sixty (360) day period applied to the Obligations in
         the manner specified in the second sentence of this subsection 3.3.1
         until payment thereof in full; and in the case of clause (iii) above,
         if either Agent or any Lender declines to permit any such repair or
         replacement or fails to respond to Borrowers within such three hundred
         sixty (360) day period, or if the applicable Company or Guarantor has
         failed to commit to replace or rebuild the damaged Property within such
         one hundred eighty (180) day period, such amount shall be

         prepayment shall be applied to the Loans in the manner specified in the
         second sentence of subsection 3.3.1 until payment thereof in full.

                  3.3.3.   Proceeds from Issuance of Additional Indebtedness. If
         any Borrower or any Guarantor issues any additional Indebtedness,
         Borrowers shall jointly and severally pay to Agent for the ratable
         benefit of Lenders, when and as received by any Borrower or any
         Guarantor and as a mandatory prepayment of the Obligations, a sum equal
         to 100% of the net proceeds to such Borrower or such Guarantor of the
         issuance of such Indebtedness; provided, that at any time that both (i)
         the outstanding principal balance of the Term Loan is less than or
         equal to $25,000,000 and (ii) the Senior Leverage Ratio is 2.00:1.0 or
         less, such percentage shall be equal to 50%. Any such prepayment shall
         be applied to the Loans in the manner specified in the second sentence
         of subsection 3.3.1 until payment thereof in full.

                  3.3.4.   Proceeds from Issuance of Additional Equity. If any
         Borrower or any Guarantor issues any additional equity (excluding (i)
         equity issued upon conversion of the Convertible Notes to equity
         Securities and (ii) equity issued upon exercise of employee options),
         Borrowers shall jointly and severally pay to Agent for the ratable
         benefit of Lenders, when and as received by any Borrower or any
         Guarantor, and as a mandatory prepayment of the Obligations, a sum
         equal to 50% of the net proceeds to such Borrower or such Guarantor of
         the issuance of such equity. Any such prepayment shall be applied to
         the Loans in the manner specified in the second sentence of subsection
         3.3.1 until payment thereof in full.

                  3.3.5.   Other Mandatory Prepayments. If any Borrower or any
         Guarantor receives any proceeds from any tax refunds, indemnity
         payments or pension plan reversions, Borrowers shall jointly and
         severally pay to Agent for the benefit of Lenders, when and as received
         by such Borrower or such Guarantor, and as a mandatory prepayment of
         the Obligations, a sum equal to 100% of such proceeds of such tax
         refund, indemnity payment or pension plan reversions; provided,
         however, that at any time that both (i) the outstanding principal
         balance of the Term Loan is less than or equal to $25,000,000 and (ii)
         the Senior Leverage Ratio is 2.00 to 1.0 or less, such percentage shall
         be 50%. Any such prepayment shall be applied to the Obligations in the
         manner specified in the third sentence of subsection 3.3.1 until
         payment thereof in full.

                  3.3.6.   LIBOR Portions. If the application of any payment
         made in accordance with the provisions of this Section 3.3 at a time
         when no Event of Default has occurred and is continuing would result in
         termination of a LIBOR Portion prior to the last day of the Interest
         Period for such LIBOR Portion, the amount of such prepayment shall not
         be applied to such LIBOR Portion, but will, at Borrowers' option, be
         held by Agent in a non-interest bearing account at a Lender or another
         bank satisfactory to Agent in its discretion, which account is in the
         name of Agent and from which account only Agent can make any
         withdrawal, in each case to be applied as such amount would otherwise
         have been applied under this Section 3.3 at the earlier to occur of (i)
         the last day of the relevant Interest Period or (ii) the occurrence of
         a Default or an Event of Default.

                  3.3.7.   Optional Prepayments. Borrowers may, at their option
         from time to time upon not less than 1 day's prior written notice to
         Agent, prepay installments of the Term Notes, provided that the amount
         of any such prepayment is at least $500,000 and in integral multiples
         of $100,000 above $500,000, and that such prepayments are made ratably
         with respect to all Term Notes. Each such prepayment shall be applied
         to the installments of principal due under the Term Notes on a ratable
         basis. Except for charges applicable to prepayments of LIBOR Term
         Portions, such prepayments shall be without premium or penalty.

                  3.3.8.   Optional Reductions of Revolving Loan Commitments.
         Borrowers may, at their option from time to time but not more than once
         in any 12 month period upon not less than 30 Business Days' prior
         written notice to Agent, terminate in whole or permanently reduce
         ratably in part, the unused portion of the Revolving Loan Commitments,
         provided, however, that (i) each such partial reduction shall be in an
         amount of $1,000,000 or integral multiples of $1,000,000 in excess
         thereof and (ii) the aggregate of all optional reductions to the
         Revolving Credit Commitments may not exceed $20,000,000 during any 12
         month period or $50,000,000 during the Term. Except for charges under
         subsection 3.2.5 applicable to prepayments of LIBOR Revolving Portions,
         such prepayments shall be without premium or penalty.

                  3.3.9.   Special Mandatory Prepayment of Term Loan. Borrowers
         will make an additional mandatory prepayment of the Term Loan on
         January 1, 2004 in the amount of $5,000,000. Such prepayment shall be
         applied to the Term Notes ratably, and to installments due thereunder
         in the inverse order of maturity until paid in full.

                  3.4.     Application of Payments and Collections.

                  3.4.1.   Collections. All items of payment received by Agent
         in immediately available funds by 12:00 noon, Chicago, Illinois, time,
         on any Business Day shall be deemed received on that Business Day. All
         items of payment received after 12:00 noon, Chicago, Illinois, time, on
         any Business Day shall be deemed received on the following Business
         Day. If as the result of collections of Accounts as authorized by
         subsection 6.2.4 hereof or otherwise, a credit balance exists in the
         Loan Account, such credit balance shall not accrue interest in favor of
         Borrowers, but shall be

                                      -25-

<PAGE>

         disbursed to a Borrower or otherwise at a Borrower's direction in the
         manner set forth in subsection 3.1.2, upon a Borrower's request at any
         time, so long as no Default or Event of Default then exists. Agent may
         at its option, offset such credit balance against any of the
         Obligations upon and during the continuance of an Event of Default.

                  3.4.2.   Apportionment, Application and Reversal of Payments.
         Principal and interest payments shall be apportioned ratably among
         Lenders (according to the unpaid principal balance of the Loans to
         which such payments relate held by each Lender). All payments shall be
         remitted to Agent and all such payments not relating to principal or
         interest of specific Loans, or not constituting payment of specific
         fees, and all proceeds of Accounts, or, except as provided in
         subsection 3.3.1, other Collateral received by Agent, shall be applied,
         ratably, subject to the provisions of this Agreement, first, to pay any
         fees, indemnities, or expense reimbursements (other than amounts
         related to Product Obligations) then due to Agent or Lenders from any
         Borrower; second, to pay interest due from Borrowers in respect of all
         Loans, including Swingline Loans and Agent Loans; third, to pay or
         prepay principal of Swingline Loans and Agent Loans; fourth, to pay or
         prepay principal of the Revolving Credit Loans (other than Swingline
         Loans and Agent Loans) and unpaid reimbursement obligations in respect
         of Letters of Credit; fifth, to pay an amount to Agent equal to all
         outstanding Letter of Credit Obligations to be held as cash Collateral
         for such Obligations (in an amount of 105% of the aggregate amount
         thereof); sixth, to pay or prepay principal of the Term Loan; seventh,
         to the payment of any other Obligation (other than amounts related to
         Product Obligations) due to the Agent or any Lender by any Borrower;
         and eighth, to pay any amounts owing in respect of Product Obligations.
         As between Agent and Borrowers, after the occurrence and during the
         continuance of an Event of Default, Agent shall have the continuing
         exclusive right to apply and reapply any and all such payments and
         collections received at any time or times hereafter by Agent or its
         agent against the Obligations, in such manner as Agent may deem
         advisable, notwithstanding any entry by Agent or any Lender upon any of
         its books and records.

                  3.5.     All Loans to Constitute One Obligation.

                  The Loans, Letters of Credit and LC Guarantees shall
constitute one general joint and several Obligation of Borrowers, and shall be
secured by Agent's Lien upon all of the Collateral.

                  3.6.     Loan Account.

                  Agent shall enter all Loans as debits to one or more loan
accounts (each, a "Loan Account") and shall also record in the Loan Account all
payments made by or on behalf of each Borrower on any Obligations and all
proceeds of Collateral which are finally paid to Agent, and may record therein,
in accordance with customary accounting practice, other debits and credits,
including interest and all charges and expenses properly chargeable to each
Borrower.

<PAGE>

                  3.7.     Statements of Account.

                  Agent will account to Borrowers monthly with a statement of
Loans, charges and payments made pursuant to this Agreement during the
immediately preceding month, and such account rendered by Agent shall be deemed
final, binding and conclusive upon Borrowers absent demonstrable error unless
Agent is notified by Borrowers in writing to the contrary within 30 days of the
date each accounting is received by Borrowers. Such notice shall only be deemed
an objection to those items specifically objected to therein.

                  3.8.     Increased Costs.

                  If any law or any governmental or quasi-governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) adopted or implemented after the date of this Agreement and having general
applicability to all banks or finance companies within the jurisdiction in which
any Lender operates (excluding, for the avoidance of doubt, the effect of and
phasing in of capital requirements or other regulations or guidelines passed
prior to the date of this Agreement), or any interpretation or application
thereof by any governmental authority charged with the interpretation or
application thereof, or the compliance of such Lender therewith, shall:

                           (i)      (1) subject such Lender to any tax with
                  respect to this Agreement (other than (a) any tax based on or
                  measured by net income or otherwise in the nature of a net
                  income tax, including, without limitation, any franchise tax
                  or any similar tax based on capital, net worth or comparable
                  basis for measurement and (b) any tax collected by a
                  withholding on payments and which neither is computed by
                  reference to the net income of the payee nor is in the nature
                  of an advance collection of a tax based on or measured by the
                  net income of the payee) or (2) change the basis of taxation
                  of payments to such Lender of principal, fees, interest or any
                  other amount payable hereunder or under any Loan Documents
                  (other than in respect of (a) any tax based on or measured by
                  net income or otherwise in the nature of a net income tax,
                  including, without limitation, any franchise tax or any
                  similar tax based on capital, net worth or comparable basis
                  for measurement and (b) any tax collected by a withholding on
                  payments and which neither is computed by reference to the net
                  income of the payee nor is in the nature of an advance
                  collection of a tax based on or measured by the net income of
                  the payee);

                           (ii)     impose, modify or hold applicable any
                  reserve (except any reserve taken into account in the
                  determination of the applicable LIBOR), special deposit,
                  assessment or similar requirement against assets held by, or
                  deposits in or for the account of, advances or loans by, or
                  other credit extended by, any office of such Lender, including
                  (without limitation) pursuant to Regulation D; or

                           (iii)    impose on such Lender or the London
                  interbank market any other condition with respect to any Loan
                  Document;

                                      -27-

and the result of any of the foregoing is to increase the cost to such Lender of
making, renewing or maintaining Loans hereunder or the result of any of the
foregoing is to reduce the rate of return on such Lender's capital as a
consequence of its obligations hereunder, or the result of any of the foregoing
is to reduce the amount of any payment (whether of principal, interest or
otherwise) in respect of any of the Loans, then, in any such case, Borrowers
shall jointly and severally pay such Lender, upon demand and certification not
later than sixty (60) days following its receipt of notice of the imposition of
such increased costs, such additional amount as will compensate such Lender for
such additional cost or such reduction, as the case may be, to the extent such
Lender has not otherwise been compensated, with respect to a particular Loan,
for such increased cost as a result of an increase in the Base Rate or the
LIBOR. An officer of the applicable Lender shall determine the amount of such
additional cost or reduced amount using reasonable averaging and attribution
methods and shall certify the amount of such additional cost or reduced amount
to Borrowers, which certification shall include a written explanation of such
additional cost or reduction to Borrowers. Such certification shall be
conclusive absent manifest error. If a Lender claims any additional cost or
reduced amount pursuant to this Section 3.8, then such Lender shall use
reasonable efforts (consistent with legal and regulatory restrictions) to
designate a different lending office or to file any certificate or document
reasonably requested by Borrowers if the making of such designation or filing
would avoid the need for, or reduce the amount of, any such additional cost or
reduced amount and would not, in the sole discretion of such Lender, be
otherwise disadvantageous to such Lender.

                  3.9.     Basis for Determining Interest Rate Inadequate.

                  In the event that Agent or any Lender shall have determined
that:

                           (i)      reasonable means do not exist for
                  ascertaining the LIBOR for any Interest Period; or

                           (ii)     Dollar deposits in the relevant amount and
                  for the relevant maturity are not available in the London
                  interbank market with respect to a proposed LIBOR Portion, or
                  a proposed conversion of a Base Rate Portion into a LIBOR
                  Portion; then

Agent or such Lender shall give Borrowers prompt written, telephonic or
electronic notice of the determination of such effect. If such notice is given,
(i) any such requested LIBOR Portion shall be made as a Base Rate Portion,
unless Borrowers shall notify Agent no later than 11:00 a.m. (Chicago, Illinois
time) three (3) Business Days prior to the date of such proposed borrowing that
the request for such borrowing shall be canceled or made as an unaffected type
of LIBOR Portion, and (ii) any Base Rate Portion which was to have been
converted to an affected type of LIBOR Portion shall be continued as or
converted into a Base Rate Portion, or, if Borrowers shall notify Agent, no
later than 11:00 a.m. (Chicago, Illinois time) three (3) Business Days prior to
the proposed conversion, shall be maintained as an unaffected type of LIBOR
Portion.

                  3.10.    Sharing of Payments, Etc.

                  If any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of any right of set-off, or otherwise) on
account of any Loan made by it in excess of its ratable share of payments on
account of Loans made by all Lenders, such Lender shall forthwith purchase from
each other Lender such participation in such Loan as shall be necessary to cause
such purchasing Lender to share the excess payment ratably with each other
Lender; provided, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each Lender
shall be rescinded and such Lender shall repay to the purchasing Lenders the
purchase price to the extent of such recovery, together with an amount equal to
such Lender's ratable share (according to the proportion of (i) the amount of
such Lender's required repayment to (ii) the total amount so recovered from the
purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered. Borrowers agree
that any Lender so purchasing a participation from another Lender pursuant to
this Section 3.10 may, to the fullest extent permitted by law, exercise all its
rights of payment (including the right of set-off) with respect to such
participation as fully as if such Lender were the direct creditor of each
Borrower in the amount of such participation. Notwithstanding anything to the
contrary contained herein, all purchases and repayments to be made under this
Section 3.10 shall be made through Agent.

                         SECTION 4. TERM AND TERMINATION

                  4.1.     Term of Agreement.

                  Subject to the right of Lenders to cease making Loans to
Borrowers during the continuance of any Default or Event of Default, this
Agreement shall be in effect from the date hereof through and including
September 30, 2006 (the "Term"), unless terminated as provided in Section 4.2
hereof.

                  4.2.     Termination.

                  4.2.1.   Termination by Lenders. Agent may, and at the
         direction of Majority Lenders shall, terminate this Agreement upon
         notice during the continuance of an Event of Default.

                  4.2.2.   Termination by Borrowers. Upon at least 30 days'
         prior written notice to Agent and Lenders, Borrowers may, at their
         option, terminate this Agreement; provided, however, no such
         termination shall be effective until Borrowers have paid or
         collateralized to Agent's reasonable satisfaction all of the
         Obligations in immediately available funds, all Letters of Credit and
         LC Guaranties have expired, terminated or have been cash collateralized
         (in an amount equal to 105% of the Dollar Equivalent of the LC Amount)
         to Agent's reasonable satisfaction and Borrowers have complied with
         subsection 3.2.5. Any notice of termination given by Borrowers shall be
         irrevocable unless all Lenders otherwise agree in writing and no Lender
         shall have any obligation to make any Loans or issue or procure any
         Letters of Credit or LC Guaranties on or after the termination date
         stated in such notice. Without limiting

                                      -29-

<PAGE>

         Borrowers' right to reduce the amount of the Revolving Loan Commitments
         pursuant to subsection 3.3.8, Borrowers may elect to terminate this
         Agreement in its entirety only. No section of this Agreement or type of
         Loan available hereunder may be terminated singly.

                  4.2.3.   Effect of Termination. All of the Obligations shall
         be immediately due and payable upon the termination date stated in any
         notice of termination of this Agreement. All undertakings, agreements,
         covenants, warranties and representations of Borrowers contained in the
         Loan Documents shall survive any such termination and Agent shall
         retain its Liens in the Collateral and Agent and each Lender shall
         retain all of its rights and remedies under the Loan Documents
         notwithstanding such termination until all Obligations have been
         discharged or paid, in full, in immediately available funds, including,
         without limitation, all Obligations under subsection 3.2.5 resulting
         from such termination. Notwithstanding the foregoing or the payment in
         full of the Obligations, Agent shall not be required to terminate its
         Liens in the Collateral unless, with respect to any loss or damage
         Agent may incur as a result of dishonored checks or other items of
         payment received by Agent from any Borrower or any Account Debtor and
         applied to the Obligations, Agent shall, at its option, (i) have
         received a written agreement satisfactory to Agent, executed by
         Borrowers and by any Person whose loans or other advances to any
         Borrower are used in whole or in part to satisfy the Obligations,
         indemnifying Agent and each Lender from any such loss or damage or (ii)
         have retained cash Collateral or other Collateral for such period of
         time as Agent, in its reasonable discretion, may deem necessary to
         protect Agent and each Lender from any such loss or damage.

                          SECTION 5. SECURITY INTERESTS

                  5.1.     Security Interest in Collateral.

                  To secure the prompt payment and performance to Agent, each
Lender and each Affiliate of Agent and each Lender of the Obligations, each
Borrower hereby grants to Agent for the benefit of itself, each Lender and each
Affiliate of Agent and each Lender a continuing Lien upon all of such Borrower's
assets, including all of the following Property and interests in Property of
such Borrower, whether now owned or existing or hereafter created, acquired or
arising and wheresoever located:

                           (i)      Accounts;

                           (ii)     Certificated Securities;

                           (iii)    Chattel Paper;

                           (iv)     Computer Hardware and Software and all
                  rights with respect thereto, including, any and all licenses,
                  options, warranties, service contracts, program services, test
                  rights, maintenance rights, support rights, improvement

                  substitutions, replacements, additions or model conversions of
                  any of the foregoing;

                           (v)      Contract Rights;

                           (xi)     General Intangibles, including Payment

together with all books, records, writings, data bases, information and other
property relating to, used or useful in connection with, or evidencing,
embodying, incorporating or referring to any of the foregoing, and all Proceeds,
products, offspring, rents, issues, profits and returns of and from any of the
foregoing; provided, that to the extent that the provisions of any lease or
license of Computer Hardware and Software or Intellectual Property expressly
prohibit (which prohibition is enforceable under applicable law) any assignment
thereof, and the grant of a security interest therein, Agent will not enforce
its security interest in the applicable Borrower's rights under such lease or
license (other than in respect of the Proceeds thereof) for so long as such
prohibition continues, it being understood that upon request of Agent, such
Borrower will in good faith use reasonable efforts to obtain consent for the
creation of a security interest in favor of Agent (and to Agent's enforcement of
such security interest) in Agent's rights under such lease or license, excluding
licenses to use JD Edwards World and One World software, for which no Lien or
consent shall be requested or obtained.

                  5.2.     Other Collateral.

                  5.2.1.   Commercial Tort Claims. The applicable Borrower shall
         promptly notify Agent in writing upon incurring or otherwise obtaining
         a Commercial Tort Claim after the Closing Date against any third party
         and, upon request of Agent, promptly enter into an amendment to this
         Agreement and do such other acts or things deemed appropriate by Agent
         to give Agent a security interest in any such Commercial Tort Claim.
         Each Borrower represents and warrants that as of the date of this
         Agreement, to its knowledge, it does not possess any Commercial Tort
         Claims other than as described on Exhibit 5.2.1 hereto.

                  5.2.2.   Other Collateral. The applicable Borrower shall
         promptly notify Agent in writing upon acquiring or otherwise obtaining
         any Collateral after the date hereof consisting of Deposit Accounts,
         Investment Property, Letter-of-Credit Rights or Electronic Chattel
         Paper and, upon the request of Agent, promptly execute such other
         documents, and do such other acts or things deemed appropriate by Agent
         to deliver to Agent control with respect to such Collateral; promptly
         notify Agent in writing upon acquiring or otherwise obtaining any
         Collateral after the date hereof consisting of Documents or Instruments
         and, upon the request of Agent, will promptly execute such other
         documents, and do such other acts or things deemed appropriate by Agent
         to deliver to Agent possession of such Documents which are negotiable
         and Instruments, and, with respect to nonnegotiable Documents, to have
         such nonnegotiable Documents issued in the name of Agent; and with
         respect to Collateral in the possession of a third party, other than
         Certificated Securities and Goods covered by a Document, obtain an
         acknowledgement from the third party that it is holding the Collateral
         for the benefit of Agent.

                  5.2.3.   Apex Trailer Leases. Upon request by Agent, the
         applicable Borrower shall promptly take such action as is reasonably
         required by Agent to perfect Agent's Lien on the Apex Trailer Leases,
         which shall include without limitation, delivery to Agent of all
         original Apex Trailer Leases and the addition to each Apex Trailer
         Lease of a stamped legend indicating that such Apex Trailer Lease

                                      -32-

<PAGE>

         is subject to a Lien in favor of Agent. The applicable Borrower shall
         promptly deliver to Agent such information as Agent may reasonably
         request from time to time with respect to each Apex Trailer Lease.

                  5.3.     Lien Perfection; Further Assurances.

                  Each Borrower shall execute such instruments, assignments or
documents as are necessary to perfect Agent's Lien upon any of the Collateral
and shall take such other action as may be required to perfect or to continue
the perfection of Agent's Lien upon the Collateral. Unless prohibited by
applicable law, each Borrower hereby authorizes Agent to execute and file any
UCC, PPSA or similar financing statement, including, without limitation,
financing statements that indicate the Collateral (i) as all assets of such
Borrower or words of similar effect, or (ii) as being of an equal or lesser
scope, or with greater or lesser detail, than as set forth in Section 5.1, on
such Borrower's behalf. Each Borrower also hereby ratifies its authorization for
Agent to have filed in any jurisdiction any like financing statements or
amendments thereto if filed prior to the date hereof. The parties agree that a
carbon, photographic or other reproduction of this Agreement shall be sufficient
as a financing statement and may be filed in any appropriate office in lieu
thereof. At Agent's request, each Borrower shall also promptly execute or cause
to be executed and shall deliver to Agent any and all documents, instruments and
agreements deemed necessary by Agent, to give effect to or carry out the terms
or intent of the Loan Documents.

                  5.4.     Lien on Realty.

                  In addition to the Property described in Sections 5.1 and 5.2
and the Property of each Guarantor described in the applicable Collateral
Documents, the due and punctual payment and performance of the Obligations shall
also be secured by the Lien created by Mortgages upon all real Property of each
Borrower or Guarantor now or hereafter owned. Each Mortgage shall be executed by
the applicable Borrower or Guarantor in favor of Agent. Each Mortgage shall be
duly recorded, at Borrowers' joint and several expense, in each office where
such recording is required to constitute a fully perfected first Lien on the
real Property covered thereby. If so requested by Agent, the applicable Borrower
or Guarantor shall deliver to Agent, at Borrowers' joint and several expense,
(i) with respect to each individual parcel of real Property with an appraised
value of $1,000,000 or less, title tract searches performed by a title insurance
company reasonably satisfactory to Agent and (ii) with respect to each
individual parcel of real Property with an appraised value in excess of
$1,000,000, mortgagee title insurance policies issued by a title insurance
company reasonably satisfactory to Agent, which policies shall be in form and
substance reasonably satisfactory to Agent and shall insure a valid first Lien
in favor of Agent, for the benefit of itself and the Lenders, on the Property
covered by each Mortgage, subject only to those exceptions reasonably acceptable
to Agent and its counsel. If so requested by Agent, with respect to each
individual parcel of real Property with an appraised value in excess of
$1,000,000, the applicable Borrower or Guarantor shall deliver to Agent an ALTA
as-built plat of survey prepared by a surveyor licensed in the state in which
such real Property is located (which surveys may be delivered within 30 days
after the Closing Date). The applicable Borrower or Guarantor shall deliver to
Agent such other documents as Agent and its counsel may reasonably request
relating to the real Property subject to the

                                      -33-

<PAGE>

Mortgages. Notwithstanding the foregoing, Borrowers shall not be required to
deliver a Mortgage, title policy or survey with respect to the real Property of
WNTC located at 9426 8th Avenue, Seattle, Washington until September 30, 2003
and then, only to the extent that such real Property has not been sold prior to
such date.

                      SECTION 6. COLLATERAL ADMINISTRATION

                  6.1.     General.

                  6.1.1.   Location of Collateral. All Collateral, other than
         (i) Inventory in transit, (ii) motor vehicles not included in Trailer
         Inventory or Apex Trailer Inventory, (iii) the Apex Trailer Inventory
         or (iv) Collateral in the possession of Agent, will at all times be
         kept by a Borrower or one of its Subsidiaries at one or more of the
         business locations set forth in Exhibit 6.1.1 hereto, as updated by
         Borrowers providing prior written notice to Agent of any new location.
         Apex Trailer Inventory shall be located either (a) at one or more of
         the business locations set forth in Exhibit 6.1.1 hereto, as updated by
         Borrowers providing prior written notice to Agent of any new location,
         or (b) at a location of a customer of the applicable Borrower, pursuant
         to a Apex Trailer Lease, as set forth in Exhibit 6.3.2 hereto, as
         updated by Borrowers providing prior written notice to Agent of any new
         location.

                  6.1.2.   Insurance of Collateral. Borrowers shall maintain and
         pay for insurance upon all Collateral wherever located and with respect
         to the business of each Borrower and each of its Subsidiaries, covering
         casualty, hazard, public liability, workers' compensation, business
         interruption and such other risks in such amounts and with such
         insurance companies as are reasonably satisfactory to Agent. Borrowers
         shall deliver certified copies of such policies to Agent as promptly as
         practicable, with satisfactory lender's loss payable endorsements,
         naming Agent as a loss payee, assignee or additional insured, as
         appropriate, as its interest may appear, showing only such other loss
         payees, assignees and additional insureds (i) as required under
         contractual arrangements customary to Borrowers' operations (but not
         involving Indebtedness for Money Borrowed) or (ii) as otherwise are
         satisfactory to Agent and with respect to business interruption
         insurance, an executed collateral assignment thereof. Each policy of
         insurance or endorsement shall contain a clause requiring the insurer
         to give not less than 10 days' prior written notice to Agent in the
         event of cancellation of the policy for nonpayment of premium and not
         less than 30 days' prior written notice to Agent in the event of
         cancellation of the policy for any other reason whatsoever and a clause
         specifying that the interest of Agent shall not be impaired or
         invalidated by any act or neglect of any Borrower, any of its
         Subsidiaries or the owner of the Property or by the occupation of the
         premises for purposes more hazardous than are permitted by said policy.
         All proceeds of business interruption insurance (if any) of each
         Borrower and its Subsidiaries shall be remitted to Agent for
         application to the outstanding balance of the Revolving Credit Loans,
         but shall not permanently reduce the Revolving Loan Commitments.

                                      -34-

<PAGE>

                  Unless Borrowers provide Agent with evidence of the insurance
         coverage required by this Agreement, Agent may, but need not, purchase
         insurance at Borrowers' joint and several expense to protect Agent's
         interests in the Properties of each Borrower and its Subsidiaries. This
         insurance may, but need not, protect the interests of each Borrower and
         its Subsidiaries. The coverage that Agent purchases may not pay any
         claim that a Borrower or any Subsidiary of such Borrower makes or any
         claim that is made against a Borrower or any such Subsidiary in
         connection with said Property. Borrowers may later cancel any insurance
         purchased by Agent, but only after providing Agent with evidence that
         Borrowers and their Subsidiaries have obtained insurance as required by
         this Agreement. If Agent purchases insurance, Borrowers will be jointly
         and severally responsible for the costs of that insurance, including
         interest and any other charges Agent may impose in connection with the
         placement of insurance, until the effective date of the cancellation or
         expiration of the insurance. The costs of the insurance may be added to
         the Obligations. The costs of the insurance may be more than the cost
         of insurance that Borrowers and the Subsidiaries may be able to obtain
         on their own.

                  6.1.3.   Protection of Collateral. Neither Agent nor any
         Lender shall be liable or responsible in any way for the safekeeping of
         any of the Collateral or for any loss or damage thereto (except for
         reasonable care in the custody thereof while any Collateral is in
         Agent's or any Lender's actual possession) or for any diminution in the
         value thereof, or for any act or default of any warehouseman, carrier,
         forwarding agency, or other person whomsoever, but the same shall be at
         Borrowers' sole risk.

                  6.2.     Administration of Accounts.

                  6.2.1.   Records, Schedules and Assignments of Accounts. Each
         Company shall keep accurate and complete records of its Accounts and
         all payments and collections thereon and shall submit to Agent on such
         periodic basis as Agent shall request a sales and collections report
         for the preceding period, in form consistent with the reports currently
         prepared by such Company with respect to such information. Concurrently
         with the delivery of each Borrowing Base Certificate described in
         subsection 8.1.4, or more frequently as reasonably requested by Agent,
         from and after the date hereof, each Company shall deliver to Agent a
         detailed aged trial balance of all of its Accounts, specifying the
         names, face values, dates of invoices and due dates for each Account
         Debtor obligated on an Account so listed ("Schedule of Accounts"), and
         upon Agent's request therefor, copies of proof of delivery and the
         original copy of all documents, including, without limitation,
         repayment histories and present status reports relating to the Accounts
         so scheduled and such other matters and information relating to the
         status of then existing Accounts as Agent shall reasonably request.
         Concurrently with the delivery of the financial statements to be
         delivered pursuant to subsection 8.1.3(i), or more frequently if so
         requested by Agent, a listing of Account Debtors, showing all names and
         addresses. If requested by Agent, each Company shall execute and
         deliver to Agent formal written assignments of all of its Accounts
         weekly or daily, which shall include all Accounts that have been
         created since the

                                      -35-

<PAGE>

         date of the last assignment, together with copies of invoices or
         invoice registers related thereto.

                  6.2.2.   Discounts, Allowances, Disputes. If a Company grants
         any discounts, allowances or credits that are not shown on the face of
         the invoice for the Account involved, such Company shall report such
         discounts, allowances or credits, as the case may be, to Agent as part
         of the next required Schedule of Accounts.

                  6.2.3.   Account Verification. Any of Agent's officers,
         employees or agents shall have the right, at any time or times
         hereafter, in the name of Agent, any designee of Agent or a Company, to
         verify the validity, amount or any other matter relating to any
         Accounts by mail, telephone, electronic communication or otherwise.
         Each Company shall cooperate fully with Agent in an effort to
         facilitate and promptly conclude any such verification process.

                  6.2.4.   Maintenance of Dominion Account. Each Company shall
         maintain a Dominion Account or Accounts pursuant to lockbox and blocked
         account arrangements acceptable to Agent with Bank and such other banks
         as may be selected by such Company. Each Company shall obtain the
         agreement by the applicable banks in favor of Agent to waive any
         recoupment, setoff rights, and any security interest in, or against,
         the funds so deposited. Each Company shall issue to any such banks an
         irrevocable letter of instruction directing such banks to deposit all
         payments or other remittances received in the lockbox and blocked
         accounts to the Dominion Account. All funds deposited in the Dominion
         Account shall be available to Borrowers at their discretion unless a
         Dominion Period is in effect. Upon the occurrence of a Dominion Event,
         Agent may, and at the direction of Majority Lenders Agent shall, send
         the appropriate notice to Borrowers to commence a Dominion Period. If a
         Dominion Period is in effect, all funds in the Dominion Account shall
         (i) immediately become the property of Agent, for the ratable benefit
         of Lenders and (ii) be applied on account of the Obligations as
         provided in subsection 3.2.1. Agent shall have the right to invoke
         three separate Dominion Periods hereunder; once a third Dominion Period
         has been commenced, it shall remain in effect until the repayment in
         full of the Obligations. Agent assumes no responsibility for such
         lockbox and blocked account arrangements, including, without
         limitation, any claim of accord and satisfaction or release with
         respect to deposits accepted by any bank thereunder. Notwithstanding
         anything to the contrary contained herein, all such lockbox and blocked
         account arrangements will be in place and operational on or before
         October 23, 2003.

                  6.2.5.   Collection of Accounts, Proceeds of Collateral. To
         expedite collection, each Company shall endeavor in the first instance
         to make collection of its Accounts for Agent. If no Default or Event of
         Default is in existence, (i) each Company shall directly collect
         remittances on account of its Accounts owing from retail customers at
         its branch locations and (ii) each Company agrees that all invoices
         rendered and other requests made by such Company for payment in respect
         of Accounts other than retail Accounts shall contain a written
         statement directing payment in respect of such Accounts to be paid to a
         lockbox established pursuant to

                                      -36-

<PAGE>

         subsection 6.2.4. All remittances received by each Company on account
         of Accounts, together with the proceeds of any other Collateral, shall
         be held as Agent's property, for its benefit and the benefit of
         Lenders, by such Company as trustee of an express trust for Agent's
         benefit and such Company shall immediately deposit same in kind in a
         blocked account or in the Dominion Account. Upon the occurrence of a
         Default or an Event of Default, each Company agrees that all Accounts
         (including retail Accounts) shall be collected by payment to a lockbox
         in the manner described in clause (ii) above. Agent retains the right
         at all times after the occurrence and during the continuance of a
         Default or an Event of Default to notify Account Debtors that each
         Company's Accounts have been assigned to Agent and to collect each
         Company's Accounts directly in its own name, or in the name of Agent's
         agent, and to charge the collection costs and expenses, including
         attorneys' fees, jointly and severally to Borrowers.

                  6.2.6.   Taxes. If an Account includes a charge for any tax
         payable to any governmental taxing authority, Agent is authorized, in
         its sole discretion, to pay the amount thereof to the proper taxing
         authority for the account of any Borrower and to charge any Borrower
         therefor, except for taxes that (i) are being actively contested in
         good faith and by appropriate proceedings and with respect to which the
         applicable Company maintains reasonable reserves on its books therefor
         and (ii) would not reasonably be expected to result in any Lien other
         than a Permitted Lien. In no event shall Agent or any Lender be liable
         for any taxes to any governmental taxing authority that may be due by
         any Company.

                  6.3.     Administration of Inventory.

                  6.3.1.   Recordkeeping; Physicals. Each Company shall keep
         separate records of its Inventory, Trailer Inventory, Bill and Hold
         Inventory and Apex Trailer Inventory, which records shall be complete
         and accurate and complete in all material respects. Borrowers shall
         furnish to Agent separate Inventory, Trailer Inventory and Bill and
         Hold Inventory reports for each Company concurrently with the delivery
         of each Borrowing Base Certificate described in subsection 8.1.4 or
         more frequently as reasonably requested by Agent, which reports will be
         in such other format and detail as Agent shall reasonably request and
         shall include a current list separately sharing all locations of such
         Company's Inventory, Trailer Inventory and Bill and Hold Inventory.
         Each Company shall conduct a physical inventory no less frequently than
         annually (or, if an Event of Default is in existence, quarterly if so
         requested by Agent), and, in each case, shall provide to Agent a report
         based on each such physical inventory promptly thereafter, together
         with such supporting information as Agent shall reasonably request.

                  6.3.2.   Apex Trailer Leases. Each Apex Trailer Lease in
         existence as of the Closing Date is listed on Exhibit 6.3.2. Exhibit
         6.3.2 also shows the name of each lessee. All lease payments will be
         directed to the lockbox and blocked account system in the manner set
         forth in subsection 6.2.5. As of the Closing Date, all of the Apex
         Trailer Leases are in full force and effect without default by any
         party thereto.

                                      -37-

<PAGE>

         Apex has unencumbered title to each item of Apex Trailer Inventory
         subject to an Apex Trailer Lease and the unencumbered right to subject
         such item of Apex Trailer Inventory to such Apex Trailer Lease.

                  6.3.3.   Vehicle Titles. Each Borrower that maintains Trailer
         Inventory or Apex Trailer Inventory shall at all times maintain in
         place its current system for processing and safekeeping of certificates
         of title for used trailers constituting part of the Trailer Inventory
         or the Apex Trailer Inventory.

                  6.4.     Administration of Equipment.

         outstanding agreements or instruments binding upon any of any
         Borrower's or any of its Subsidiaries' partners, members or

         hereof, no Inventory is stored with a bailee, distributor, warehouseman

         and each of its Subsidiaries has good, indefeasible and marketable

                  purports to be, and it is not evidenced by a judgment;

                                      -40-

<PAGE>

                           (ii)     it arises out of a completed, bona fide sale
                  and delivery of goods or rendition of services by such
                  Company, in the ordinary course of its business and in
                  accordance with the terms and conditions of all purchase
                  orders, contracts or other documents relating thereto and
                  forming a part of the contract between such Company and the
                  Account Debtor;

                           (iii)    it is for a liquidated amount maturing as
                  stated in the duplicate invoice covering such sale or
                  rendition of services, a copy of which has been furnished or
                  is available to Agent;

                           (iv)     there are no facts, events or occurrences
                  which in any way impair the validity or enforceability of any
                  Accounts or tend to reduce the amount payable thereunder from
                  the face amount of the invoice and statements delivered or
                  made available to Agent with respect thereto;

                           (v)      to the best of such Company's knowledge, the
                  Account Debtor thereunder (1) had the capacity to contract at
                  the time any contract or other document giving rise to the
                  Account was executed and (2) such Account Debtor is Solvent;
                  and

                           (vi)     to the best of such Company's knowledge,
                  there are no proceedings or actions which are threatened or
                  pending against the Account Debtor thereunder which might
                  result in any material adverse change in such Account Debtor's
                  financial condition or the collectibility of such Account.

                  7.1.9.   Equipment. The Equipment of each Borrower and each of
         its Subsidiaries is maintained pursuant to customary industry standards
         established by Borrowers prior to the Closing Date, and all necessary
         replacements of and repairs thereto shall be made so that the operating
         efficiency thereof shall be maintained and preserved, reasonable wear
         and tear excepted. Neither any Borrower nor any of its Subsidiaries
         will permit any Equipment to become affixed to any real Property leased
         to any Borrower or any of its Subsidiaries so that an interest arises
         therein under the real estate laws of the applicable jurisdiction
         unless the landlord of such real Property has executed a landlord
         waiver or leasehold mortgage in favor of and in form reasonably
         acceptable to Agent, and no Borrower will permit any of the Equipment
         of any Borrower or any of its Subsidiaries to become an accession to
         any personal Property other than Equipment that is subject to first
         priority (except for Permitted Liens) Liens in favor of Agent.

                  7.1.10.  Financial Statements; Fiscal Year. The Consolidated
         balance sheets of Wabash and its Subsidiaries (including the accounts
         of all Subsidiaries of Wabash and their respective Subsidiaries for the
         respective periods during which a Subsidiary relationship existed) as
         of December 31, 2002, and the related statements of income, changes in
         shareholder's equity, and changes in financial position for the period
         ended on such date delivered to Agent and Lenders, have been prepared
         in accordance with GAAP, and present fairly in all material respects
         the financial positions of Wabash

                                      -41-

<PAGE>

         and such Persons, taken as a whole, at such date and the results of
         Wabash's and such Persons' operations, taken as a whole, for such
         period. As of the date hereof, since June 30, 2003, there has been no
         material adverse change in the financial position of Wabash and such
         other Persons, taken as a whole, as reflected in the balance sheets as
         of such date delivered to Agent and Lenders. For purposes of such
         representation, the charges described on Exhibit 7.1.10 hereto shall
         not constitute material adverse changes. As of the date hereof, the
         fiscal year of Wabash and each of its Subsidiaries ends on December 31
         of each year.

                  7.1.11.  Full Disclosure. The financial statements referred to
         in subsection 7.1.10 hereof do not, nor does this Agreement or any
         other written statement of any Borrower to Agent or any Lender contain
         any untrue statement of a material fact or omit a material fact
         necessary to make the statements contained therein or herein not
         misleading. There is no fact which any Borrower has failed to disclose
         to Agent or any Lender in writing which could reasonably be expected to
         have a Material Adverse Effect.

                  7.1.12.  Solvent Financial Condition. After giving effect to
         the initial Loans to be made and the initial Letters of Credit and LC
         Guaranties to be issued hereunder, and the consummation of the other
         transactions contemplated hereby, each of Wabash, each other Borrower
         and each of their respective Subsidiaries will be Solvent.

                  7.1.13.  Surety Obligations. Except as set forth on Exhibit
         7.1.13, as of the date hereof, neither any Borrower nor any of its
         Subsidiaries is obligated as surety or indemnitor under any surety or
         similar bond or other contract or has issued or entered into any
         agreement to assure payment, performance or completion of performance
         of any undertaking or obligation of any Person.

                  7.1.14.  Taxes. The federal tax identification number of each
         Borrower and each of its Subsidiaries is shown on Exhibit 7.1.14
         hereto, as updated from time to time by notice to Agent. Each Borrower
         and each of its Subsidiaries has filed all applicable federal, state
         and local tax returns and other reports relating to taxes it is
         required by law to file, and has paid, or made provision for the
         payment of, all taxes, assessments, fees, levies and other governmental
         charges upon it, its income and Properties as and when such taxes,
         assessments, fees, levies and charges are due and payable, unless and
         to the extent any thereof are being actively contested in good faith
         and by appropriate proceedings, each Borrower and each of its
         Subsidiaries maintains reasonable reserves on its books therefor, no
         Lien has arisen to secure such amounts and no Collateral has become
         subject to forfeiture or loss as a result of such contest. The
         provision for taxes on the books of each Borrower and its Subsidiaries
         is adequate for all years not closed by applicable statutes, and for
         the current fiscal year.

                  7.1.15.  Brokers. Except as shown on Exhibit 7.1.15 hereto,
         there are no claims for brokerage commissions, finder's fees or
         investment banking fees payable

         by any Borrower or any of its Subsidiaries in connection with the
         transactions contemplated by this Agreement.

                  7.1.16.  Patents, Trademarks, Copyrights and Licenses. Each
         Borrower and each of its Subsidiaries owns, possesses or licenses or
         has the right to use all the patents, trademarks, service marks, trade
         names, copyrights, licenses and other Intellectual Property necessary
         for the present and planned future conduct of its business without any
         known conflict with the rights of others, except for such conflicts as
         could not reasonably be expected to have a Material Adverse Effect. All
         such patents, trademarks, service marks, tradenames, copyrights,
         licenses, and other similar rights as of the date hereof are listed on
         Exhibit 7.1.16 hereto, as updated from time to time by notice to Agent.
         As of the date hereof, no claim has been asserted to any Borrower or
         any of its Subsidiaries which is currently pending that their use of
         their Intellectual Property or the conduct of their business does or
         may infringe upon the Intellectual Property rights of any third party.
         To the knowledge of each Borrower and except as set forth on Exhibit
         7.1.16 hereto, as of the date hereof, no Person is engaging in any
         activity that infringes in any material respect upon any Borrower's or
         any of its Subsidiaries material Intellectual Property. Except as set
         forth on Exhibit 7.1.16, each Borrower's and each of its Subsidiaries
         (i) material trademarks, service marks, and copyrights are registered
         with the U.S. Patent and Trademark Office or in the U.S. Copyright
         Office, as applicable, or similarly registered in Canada and (ii)
         material license agreements and similar arrangements relating to its
         Inventory (1) permits, and does not restrict, the assignment by any
         Borrower or any of its Subsidiaries to Agent, or any other Person
         designated by Agent, of all of such Borrower's or such Subsidiary's, as
         applicable, rights, title and interest pertaining to such license
         agreement or such similar arrangement and (2) would permit the
         continued use by such Borrower or such Subsidiary, or Agent or its
         assignee, of such license agreement or such similar arrangement and the
         right to sell Inventory subject to such license agreement for a period
         of no less than 6 months after a default or breach of such agreement or
         arrangement. The consummation and performance of the transactions and
         actions contemplated by this Agreement and the other Loan Documents,
         including without limitation, the exercise by Agent of any of its
         rights or remedies under Section 10, will not result in the termination
         or impairment of any of any Borrower's or any of its Subsidiaries
         ownership or rights relating to its Intellectual Property, except for
         such Intellectual Property rights the loss or impairment of which could
         not reasonably be expected to have a Material Adverse Effect. Except as
         listed on Exhibit 7.1.16 and except as could not reasonably be expected
         to have a Material Adverse Effect, (i) neither any Borrower nor any of
         its Subsidiaries is in breach of, or default under, any term of any
         license or sublicense with respect to any of its Intellectual Property
         and (ii) to the knowledge of each Borrower, no other party to such
         license or sublicense is in breach thereof or default thereunder, and
         such license is valid and enforceable.

                  7.1.17.  Governmental Consents. Each Borrower and each of its
         Subsidiaries has, and is in good standing with respect to, all
         governmental consents, approvals,

         franchises necessary to continue to conduct its business as heretofore
         or proposed to be conducted by it and to own or lease and operate its
         Properties as now owned or leased by it, except where the failure to
         obtain, possess or so maintain such rights could not reasonably be
         expected to have a Material Adverse Effect.

                  7.1.18.  Compliance with Laws. Each Borrower and each of its
         Subsidiaries has duly complied, and its Properties, business operations
         and leaseholds are in compliance with, the provisions of all federal,
         state and local laws, rules and regulations applicable to such Borrower
         or such Subsidiary (including without limitation Environmental Laws),
         as applicable, its Properties or the conduct of its business, except
         for such non-compliance as could not reasonably be expected to have a
         Material Adverse Effect, and there have been no citations, notices or
         orders of noncompliance issued to any Borrower or any of its
         Subsidiaries under any such law, rule or regulation, except where such
         noncompliance could not reasonably be expected to have a Material
         Adverse Effect. Each Borrower and each of its Subsidiaries has
         established and maintains an adequate monitoring system to insure that
         it remains in compliance in all material respects with all federal,
         state and local rules, laws and regulations applicable to it. No
         Inventory has been produced in violation of the Fair Labor Standards
         Act (29 U.S.C. Section 201 et seq.), as amended.

                  7.1.19.  Restrictions. Neither any Borrower nor any of its
         Subsidiaries is a party or subject to any contract or agreement which
         restricts its right or ability to incur Indebtedness, other than as set
         forth on Exhibit 7.1.19 hereto, none of which prohibit the execution of
         or compliance with this Agreement or the other Loan Documents by any
         Borrower or any of its Subsidiaries, as applicable.

                  7.1.20.  Litigation. Except as set forth on Exhibit 7.1.20
         hereto, there are no actions, suits, proceedings or investigations
         pending, or to the knowledge of any Borrower, threatened, against or
         affecting any Borrower or any of its Subsidiaries, or the business,
         operations, Properties, prospects, profits or condition of any Borrower
         or any of its Subsidiaries which, singly or in the aggregate, could
         reasonably be expected to have a Material Adverse Effect. Neither any
         Borrower nor any of its Subsidiaries is in default with respect to any
         order, writ, injunction, judgment, decree or rule of any court,
         governmental authority or arbitration board or tribunal, which, singly
         or in the aggregate, could reasonably be expected to have a Material
         Adverse Effect.

                  7.1.21.  No Defaults. No event has occurred and no condition
         exists which would, upon or after the execution and delivery of this
         Agreement or any Borrower's performance hereunder, constitute a Default
         or an Event of Default. Neither any Borrower nor any of its
         Subsidiaries is in default in (and no event has occurred and no
         condition exists which constitutes, or which the passage of time or the
         giving of notice or both would constitute, a default in) the payment of
         any Indebtedness to any Person for Money Borrowed in excess of
         $1,000,000.

                  7.1.22.  Leases. Exhibit 7.1.22 hereto is a complete listing
         as of the date hereof of all capitalized and operating personal
         Property leases with aggregate payments in excess of $500,000 per lease
         in any calendar year of each Borrower and its Subsidiaries and all real
         Property leases of each Borrower and its Subsidiaries. Each Borrower
         and each of its Subsidiaries is in full compliance with all of the
         terms of each of its respective capitalized and operating leases,
         except where the failure to so comply could not reasonably be expected
         to have a Material Adverse Effect.

                  7.1.23.  Pension Plans. As of the date hereof, except as
         disclosed on Exhibit 7.1.23 hereto (as updated from time to time by
         notice to Agent), neither any Borrower nor any of its Subsidiaries has
         any Plan, or any other employee benefit plan established under the laws
         of any jurisdiction, including without limitation the laws of Canada.
         Each Borrower and each of its Subsidiaries is in compliance with the
         requirements of ERISA and the regulations promulgated thereunder with
         respect to each Plan, except where the failure to so comply could not
         reasonably be expected to have a Material Adverse Effect. No fact or
         situation that could reasonably be expected to result in a material
         adverse change in the financial condition of each Borrower and its
         Subsidiaries exists in connection with any Plan. Neither any Borrower
         nor any of its Subsidiaries has any withdrawal liability in connection
         with a Multiemployer Plan.

                  7.1.24.  Trade Relations. There exists no actual or, to each
         Borrower's knowledge, threatened termination, cancellation or
         limitation of, or any modification or change in, the business
         relationship between any Borrower or any of its Subsidiaries and any
         customer or any group of customers whose purchases individually or in
         the aggregate are material to the business of such Borrower and its
         Subsidiaries, or with any material supplier, except in each case, where
         the same could not reasonably be expected to have a Material Adverse
         Effect, and there exists no present condition or state of facts or
         circumstances which would prevent any Borrower or any of its
         Subsidiaries from conducting such business after the consummation of
         the transactions contemplated by this Agreement in substantially the
         same manner in which it has heretofore been conducted.

                  7.1.25.  Labor Relations. Except as described on Exhibit
         7.1.25 hereto, as of the date hereof, neither any Borrower nor any of
         its Subsidiaries is a party to any collective bargaining agreement.
         There are no material grievances, disputes or controversies with any
         union or any other organization of any Borrower's or any of its
         Subsidiaries employees, or threats of strikes, work stoppages or any
         asserted pending demands for collective bargaining by any union or
         organization, except those that could not reasonably be expected to
         have a Material Adverse Effect.

                  7.1.26.  Business Activity. No Inactive Subsidiary engages in
         any business activity or has any material assets, or has or incurs any
         Indebtedness, other than the performance of its obligations under
         intercompany agreements and agreements with its shareholders that have
         been disclosed to Agent in writing.

                  7.1.27.  Apex Sale. The Apex Sale has been consummated
         pursuant to the terms of the Apex Sale Documents and in compliance with
         all applicable laws, with gross cash proceeds to Borrowers of not less
         than $55,000,000, prior to making any purchase price adjustment
         calculations based on changes to working capital, as provided in the
         Apex Sale Documents, all of which were used to repay existing
         Indebtedness for Money Borrowed and transaction fees and expenses.

                  7.1.28.  Environmental Protection. No event or condition has
         occurred or is occurring with respect to any Borrower or any of its
         Subsidiaries relating to any Environmental Law, any Hazardous
         Materials, or any investigation, notice, notice of violation, claim,
         action, suit, proceeding, demand, abatement order or other order or
         directive by any governmental authority or any other person relating to
         any Environmental Law or Hazardous Materials, which individually or in
         the aggregate has had or could reasonably be expected to have a
         Material Adverse Effect. Compliance with all requirements under current
         Environmental Laws or pending federal and/or state environmental laws
         and regulations, will not, individually or in the aggregate, have a
         reasonable possibility of giving rise to a Material Adverse Effect.

                  7.1.29.  Government Regulation. Neither any Borrower nor any
         of its Subsidiaries is an "investment company" or an "affiliated
         person" of, or "promoter" or "principal underwriter" for, an
         "investment company," as such terms are defined in the Investment
         Company Act of 1940. Neither any Borrower nor any of its Subsidiaries
         is 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. The making of the Loans by Lenders
         to Borrowers, the incurrence of the LC Obligations on behalf of
         Borrowers, the application of the proceeds thereof and payment thereof
         will not violate any provision of any such statute or any rule,
         regulation or order issued by the Securities and Exchange Commission.

                  7.1.30.  Margin Regulations. Neither any Borrower nor any of
         its Subsidiaries is engaged, principally or as one of its important
         activities, in the business of extending credit for the purpose of
         "purchasing" or "carrying" and "margin stock" as such terms are defined
         in Regulation U of the Federal Reserve Board as now and from time to
         time hereafter in effect (such securities being referred to herein as
         "Margin Stock"). Neither any Borrower nor any of its Subsidiaries owns
         any Margin Stock, and none of the proceeds of the Loans or other
         extensions of credit under this Agreement will be used, directly or
         indirectly, for the purpose of 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 cause any of the Loans or other extensions of
         credit under this Agreement to be considered a "purpose credit" within
         the meaning of Regulations T, U or X of the Federal Reserve Board.
         Neither any Borrower nor any of its Subsidiaries will take or permit to
         be taken any action that might cause any Loan Document to violate any
         regulation of the Federal Reserve Board.

                  7.1.31.  Wind Down Subsidiaries. As of the Closing Date,
         Borrowers are in the process of winding down the business and
         operations of each of the Wind Down Subsidiaries.

                  7.1.32.  Vehicles. Each Borrower or Guarantor that at any time
         holds title to any used vehicles returned to it on a trade-in basis or
         otherwise is primarily in the business of selling new and used
         vehicles.

                  7.1.33.  Joint Venture Investments. Each of the joint venture
         investments of each Borrower and its Subsidiaries on the Closing Date
         are listed on Exhibit 7.1.33 hereto. All of such joint ventures are
         being wound down. None of such joint ventures has any material assets,
         operations or liabilities, contingent or otherwise. Neither any
         Borrower nor any Subsidiary has any ongoing funding obligations
         (contingent or otherwise) in respect of any such joint venture.

                  7.2.     Continuous Nature of Representations and Warranties.

                  Each representation and warranty contained in this Agreement
and the other Loan Documents shall be deemed to have been remade at the time of
each request for a Loan, Letter of Credit or LC Guaranty hereunder and at the
time that any Loan is deemed to have been made under subsection 3.1.1. Each such
request for a Loan, Letter of Credit or LC Guaranty (and the making of any Loan
deemed to have been made under subsection 3.1.1) shall constitute a
representation by Borrowers that such representations and warranties remain
accurate, complete and not misleading at such time, except to the extent that
such representations and warranties relate solely to an earlier date and except
for changes in the nature of a Borrower's or one of such Borrower's Subsidiary's
business or operations that would render the information in any exhibit attached
hereto or to any other Loan Document either inaccurate, incomplete or
misleading, so long as Majority Lenders have consented to such changes or such
changes are expressly permitted by this Agreement.

                  7.3.     Survival of Representations and Warranties.

                  All representations and warranties of each Borrower contained
in this Agreement or any of the other Loan Documents shall survive the
execution, delivery and acceptance thereof by Agent and each Lender and the
parties thereto and the closing of the transactions described therein or related
thereto.

                 SECTION 8. COVENANTS AND CONTINUING AGREEMENTS

                  8.1.     Affirmative Covenants.

                  During the Term, and thereafter for so long as there are any
Obligations outstanding, Borrowers jointly and severally covenant that they
shall:

                  8.1.1.   Visits and Inspections; Lender Meeting. Permit (i)
         representatives of Agent (who may be accompanied by representatives of
         each Lender), and during the continuation of any Default or Event of
         Default any Lender, from time to time, as

                                      -47-

<PAGE>

         often as may be reasonably requested, but only during normal business
         hours, to visit and inspect the Properties of each Borrower and each of
         its Subsidiaries, inspect, audit and make extracts from its books and
         records, and discuss with its officers, its employees and its
         independent accountants, each Borrower's and each of its Subsidiaries'
         business, assets, liabilities, financial condition, business prospects
         and results of operations and (ii) appraisers engaged pursuant to
         Section 2.10 (whether or not personnel of Agent), from time to time, as
         often as may be reasonably requested, but only during normal business
         hours, to visit and inspect the Properties of each Borrower and each of
         its Subsidiaries, for the purpose of completing appraisals pursuant to
         Section 2.10. Agent, if no Default or Event of Default then exists,
         shall give the applicable Borrower reasonable prior notice of any such
         inspection or audit. Without limiting the foregoing, Borrowers will
         participate and will cause their key management personnel to
         participate in a meeting with Agent and Lenders once during each year
         (except that during the continuation of an Event of Default such
         meetings may be held more frequently as requested by Agent or Majority
         Lenders), which meeting(s) shall be held at such times and such places
         as may be reasonably requested by Agent.

                  8.1.2.   Notices. Promptly notify Agent in writing of the
         occurrence of any event or the existence of any fact which renders any
         representation or warranty in this Agreement or any of the other Loan
         Documents inaccurate, incomplete or misleading in any material respect
         as of the date made or remade. In addition, each Borrower agrees to
         provide Agent with prompt written notice of any change in the
         information disclosed in any Exhibit hereto, in each case after giving
         effect to the materiality limits and Material Adverse Effect
         qualifications contained therein.

                  8.1.3.   Financial Statements. Keep, and cause each of its
         Subsidiaries, to keep, adequate records and books of account with
         respect to its business activities in which proper entries are made in
         accordance with customary accounting practices reflecting all its
         financial transactions; and cause to be prepared and furnished to Agent
         and each Lender, the following, all to be prepared in accordance with
         GAAP applied on a consistent basis, unless Wabash's certified public
         accountants concur in any change therein and such change is disclosed
         to Agent and is consistent with GAAP:

                           (i)      not later than 90 days after the close of
                  each fiscal year of Wabash, audited financial statements of
                  Wabash and its Subsidiaries as of the end of such year, on a
                  Consolidated basis, certified by a firm of independent
                  certified public accountants of recognized standing selected
                  by Wabash but acceptable to Agent, prepared in accordance with
                  GAAP, fairly presenting in all material respects the financial
                  position and results of operations of Wabash and its
                  Subsidiaries for such fiscal year and presented without
                  qualification (except for a qualification for a change in
                  accounting principles with which the accountant concurs) and
                  without any going concern qualification, exception or
                  assumption or any qualification, exception or assumption
                  relating to the scope

                  that such statements need not contain notes;

                  reasons for any significant variations. The information above
                  shall be presented in reasonable detail and shall be certified
                  by the Treasurer of Wabash to the effect that such information
                  fairly presents in all material respects the results of
                  operation and financial condition of Wabash and its
                  Subsidiaries as at the dates and for the periods indicated;

                           (iv)     upon request by Agent, promptly after the

                  Wabash, any other Borrower or any of any Borrower's
                  Subsidiaries has made available to its Securities holders and
                  copies of any regular, periodic and special reports or
                  registration statements which Wabash, any other Borrower or
                  any Subsidiary of any Borrower files with the Securities and

         other Borrower; or (d) a Borrower or a Subsidiary of a Borrower shall

         Borrower, such Subsidiary or such Guarantor.

                  10.1.16. Judgments. Any money judgments, writ of attachment or
         similar processes (collectively, "Judgments") in excess of amounts
         covered by insurance (not including self-insurance or other retentions)

         such Judgment or Judgments (in the aggregate) could

                                      -65-

<PAGE>

         reasonably be expected to have a Material Adverse Effect, in each case

continuance of an Event of Default, (i) Agent may, and upon the direction of

and/or (ii) Agent may, and upon the direction of Majority Lenders, Agent shall,
declare all or any portion of the Obligations at once due and payable without
presentment, demand protest or further notice by Agent or any Lender, and
Borrowers shall forthwith pay to Agent, the full amount of such Obligations,
provided, that upon the occurrence of an Event of Default specified in
subsection 10.1.8 hereof, the Revolving Loan Commitments shall automatically be
terminated and all of the Obligations shall become automatically due and
payable, in each case without declaration, notice or demand by Agent or any
Lender.

                  10.3.    Other Remedies.

                  Upon the occurrence and during the continuance of an Event of
Default, Agent shall have and may exercise from time to time the following other
rights and remedies:

                  10.3.1.  All of the rights and remedies of a secured party
         under the UCC or under other applicable law, and all other legal and
         equitable rights to which Agent or Lenders may be entitled, all of
         which rights and remedies shall be cumulative and shall be in addition
         to any other rights or remedies contained in this Agreement or any of
         the other Loan Documents, and none of which shall be exclusive.

                  10.3.2.  The right to take immediate possession of the
         Collateral, and to (i) require each Borrower and each of its
         Subsidiaries to assemble the Collateral, at Borrower's joint and
         several expense, and make it available to Agent at a place designated
         by Agent which is reasonably convenient to both parties, and (ii) enter
         any premises where any of the Collateral shall be located and to keep
         and store the Collateral on said premises until sold (and if said
         premises be the Property of any Borrower or any of its Subsidiaries,
         such Borrower agrees not to charge, or permit such Subsidiary to
         charge, Agent for storage thereof).

                  10.3.3.  The right to sell or otherwise dispose of all or any
         Collateral in its then condition, or after any further manufacturing or
         processing thereof, at public or private sale or sales, with such
         notice as may be required by law, in lots or in bulk, for cash or on
         credit, all as Agent, in its sole discretion, may deem advisable. Agent
         may, at Agent's option, disclaim any and all warranties regarding the
         Collateral in connection with any such sale. Each Borrower agrees that
         10 days' written notice to such Borrower or any of its Subsidiaries of
         any public or private sale or other

                                      -66-

<PAGE>

         disposition of Collateral shall be reasonable notice thereof, and such
         sale shall be at such locations as Agent may designate in said notice.
         Agent shall have the right to conduct such sales on any Borrower's or
         any of its Subsidiaries' premises, without charge therefor, and such
         sales may be adjourned from time to time in accordance with applicable
         law. Agent shall have the right to sell, lease or otherwise dispose of
         the Collateral, or any part thereof, for cash, credit or any
         combination thereof, and Agent, on behalf of Lenders, may purchase all
         or any part of the Collateral at public or, if permitted by law,
         private sale and, in lieu of actual payment of such purchase price, may
         set off the amount of such price against the Obligations. The proceeds
         realized from the sale of any Collateral shall be applied, after
         allowing 2 Business Days for collection, in the manner provided in
         subsection 3.4.2. If any deficiency shall arise, each Borrower and each
         Guarantor shall remain jointly and severally liable to Agent and
         Lenders therefor.

                  10.3.4.  Agent is hereby granted a license or other right to
         use, without charge, each Borrower's and each of its Subsidiaries'
         labels, patents, copyrights, licenses, rights of use of any name, trade
         secrets, tradenames, trademarks and advertising matter, or any Property
         of a similar nature, as it pertains to the Collateral, in completing,
         advertising for sale and selling any Collateral and each Borrower's and
         each of its Subsidiaries' rights under all licenses and all franchise
         agreements shall inure to Agent's benefit.

                  10.3.5.  Agent may, at its option, require Borrowers to
         deposit with Agent funds equal to 105% of the Dollar Equivalent of the
         LC Amount and, if Borrowers fail to promptly make such deposit, Agent
         may advance such amount as a Revolving Credit Loan (whether or not an
         Overadvance is created thereby). Each such Revolving Credit Loan shall
         be secured by all of the Collateral and shall constitute a Base Rate
         Portion. Any such deposit or advance shall be held by Agent as a
         reserve to fund future payments on such LC Guaranties and future
         drawings against such Letters of Credit. At such time as all LC
         Guaranties have been paid or terminated and all Letters of Credit have
         been drawn upon or expired, any amounts remaining in such reserve shall
         be applied against any outstanding Obligations, or, if all Obligations
         have been indefeasibly paid in full, returned to Borrowers.

                  10.3.6.  Notwithstanding any provision of this Agreement or
         any other Loan Document to the contrary, Agent shall not take any
         action to foreclose upon, acquire or take possession of or occupy, or
         exercise any remedies by which it will take title or otherwise come
         into ownership in respect of Collateral consisting of real Property
         listed on Exhibit 10.3.6 (the "Affected Collateral") or purchase or
         otherwise acquire (including in lieu of actual payment of a purchase
         price) any stock or other equity interest in any Company or other
         Person that owns the Affected Collateral unless and until (i) Lenders
         have obtained, at Borrowers' joint and several expense, a Phase II
         environmental site assessment with respect to the Affected Collateral,
         prepared by an environmental consultant reasonably acceptable to
         Lenders and (ii) each Lender has confirmed that no remediation is
         required by such Lender or that any remediation has

                                      -67-

<PAGE>

         been completed to the satisfaction of such Lender with respect to the
         Affected Collateral.

                  10.4.    Set Off and Sharing of Payments.

                  In addition to any rights now or hereafter granted under
applicable law and not by way of limitation of any such rights, during the
continuance of any Event of Default, each Lender is hereby authorized by each
Borrower at any time or from time to time, with prior written consent of Agent
and with reasonably prompt subsequent notice to such Borrower (any prior or
contemporaneous notice to such Borrower being hereby expressly waived) to set
off and to appropriate and to apply any and all (i) balances held by such Lender
at any of its offices for the account of such Borrower or any of its
Subsidiaries (regardless of whether such balances are then due to such Borrower
or its Subsidiaries), and (ii) other property at any time held or owing by such
Lender to or for the credit or for the account of such Borrower or any of its
Subsidiaries, against and on account of any of the Obligations. Any Lender
exercising a right to set off shall, to the extent the amount of any such set
off exceeds its Revolving Loan Percentage of the amount set off, purchase for
cash (and the other Lenders shall sell) interests in each such other Lender's
pro rata share of the Obligations as would be necessary to cause such Lender to
share such excess with each other Lender in accordance with their respective
Revolving Loan Percentages. Each Borrower agrees, to the fullest extent
permitted by law, that any Lender may exercise its right to set off with respect
to amounts in excess of its pro rata share of the Obligations and upon doing so
shall deliver such excess to Agent for the benefit of all Lenders in accordance
with the Revolving Loan Percentages.

                  10.5.    Remedies Cumulative; No Waiver.

                  All covenants, conditions, provisions, warranties, guaranties,
indemnities, and other undertakings of each Borrower contained in this Agreement
and the other Loan Documents, or in any document referred to herein or contained
in any agreement supplementary hereto or in any schedule or in any Guaranty
Agreement given to Agent or any Lender or contained in any other agreement
between any Lender and such Borrower or between Agent and such Borrower,
heretofore, concurrently, or hereafter entered into, shall be deemed cumulative
to and not in derogation or substitution of any of the terms, covenants,
conditions, or agreements of such Borrower herein contained. The failure or
delay of Agent or any Lender to require strict performance by any Borrower of
any provision of this Agreement or to exercise or enforce any rights, Liens,
powers, or remedies hereunder or under any of the aforesaid agreements or other
documents or security or Collateral shall not operate as a waiver of such
performance, Liens, rights, powers and remedies, but all such requirements,
Liens, rights, powers, and remedies shall continue in full force and effect
until all Loans and other Obligations owing or to become owing from such
Borrower to Agent and each Lender have been fully satisfied. None of the
undertakings, agreements, warranties, covenants and representations of any
Borrower contained in this Agreement or any of the other Loan Documents and no
Default or Event of Default by any Borrower under this Agreement or any other
Loan Documents shall be deemed to have been suspended or waived by Lenders,
unless such suspension or waiver is by an instrument in writing specifying such
suspension or waiver and is signed by a duly authorized representative of Agent
and directed to Borrowers.

                  Each Lender hereby appoints and authorizes Agent to take such
action on its behalf and to exercise such powers under this Agreement and the
other Loan Documents as are delegated to Agent by the terms hereof and thereof,
together with such powers as are reasonably incidental thereto. Each Lender
hereby acknowledges that Agent shall not have by reason of this Agreement
assumed a fiduciary relationship in respect of any Lender. In performing its
functions and duties under this Agreement, Agent shall act solely as agent of
Lenders and shall not assume, or be deemed to have assumed, any obligation
toward, or relationship of agency or trust with or for, any Borrower. As to any
matters not expressly provided for by this Agreement and the other Loan
Documents (including without limitation enforcement and collection of the
Notes), Agent may, but shall not be required to, exercise any discretion or take
any action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the Majority Lenders, whenever such instruction shall be requested by Agent or
required hereunder, or a greater or lesser number of Lenders if so required
hereunder, and such instructions shall be binding upon all Lenders; provided,
that Agent shall be fully justified in failing or refusing to take any action
which exposes Agent to any liability or which is contrary to this Agreement, the
other Loan Documents or applicable law, unless Agent is indemnified to its
satisfaction by the other Lenders against any and all liability and expense
which it may incur by reason of taking or continuing to take any such action. If
Agent seeks the consent or approval of the Majority Lenders (or a greater or
lesser number of Lenders as required in this Agreement), with respect to any
action hereunder, Agent shall send notice thereof to each Lender and shall
notify each Lender at any time that the Majority Lenders (or such greater or
lesser number of Lenders) have instructed Agent to act or refrain from acting
pursuant hereto.

                  11.2.    Agent's Reliance, Etc.

                  Neither Agent, any Affiliate of Agent, nor any of their
respective directors, officers, agents or employees shall be liable for any
action taken or omitted to be taken by it or them under or in connection with
this Agreement or the other Loan Documents, except for its or their own gross
negligence or willful misconduct. Without limitation of the generality of the
foregoing, Agent: (i) may treat each Lender party hereto as the holder of
Obligations until Agent receives written notice of the assignment or transfer of
such Lender's portion of the Obligations signed by such Lender and in form
reasonably satisfactory to Agent; (ii) may consult with legal counsel,
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts, (iii) makes
no warranties or representations to any Lender and shall not be responsible to
any Lender for any recitals, statements, warranties or representations made in
or in connection with this Agreement or any other Loan Documents; (iv) shall not
have any duty beyond Agent's customary practices in respect of loans in which
Agent is the only lender to ascertain or to inquire as to the performance or
observance of any of the terms, covenants or conditions of this Agreement or

                                      -69-

<PAGE>

the other Loan Documents on the part of any Borrower, to inspect the property
(including the books and records) of any Borrower, to monitor the financial
condition of any Borrower or to ascertain the existence or possible existence or
continuation of any Default or Event of Default; (v) shall not be responsible to
any Lender for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement or the other Loan Documents
or any other instrument or document furnished pursuant hereto or thereto; (vi)
shall not be liable to any Lender for any action taken, or inaction, by Agent
upon the instructions of Majority Lenders pursuant to Section 11.1 hereof or
refraining to take any action pending such instructions; (vii) shall not be
liable for any apportionment or distributions of payments made by it in good
faith pursuant to Section 3 hereof; (viii) shall incur no liability under or in
respect of this Agreement or the other Loan Documents by acting upon any notice,
consent, certificate, message or other instrument or writing (which may be by
telephone, facsimile, telegram, cable or telex) believed in good faith by it to
be genuine and signed or sent by the proper party or parties; and (ix) may
assume that no Event of Default has occurred and is continuing, unless Agent has
actual knowledge of the Event of Default, has received notice from a Borrower or
a Borrower's independent certified public accountants stating the nature of the
Event of Default, or has received notice from a Lender stating the nature of the
Event of Default and that such Lender considers the Event of Default to have
occurred and to be continuing. In the event any apportionment or distribution
described in clause (vii) above is determined to have been made in error, the
sole recourse of any Person to whom payment was due but not made shall be to
recover from the recipients of such payments any payment in excess of the amount
to which they are determined to have been entitled.

                  11.3.    Fleet and Affiliates.

                  With respect to its commitment hereunder to make Loans, Fleet
shall have the same rights and powers under this Agreement and the other Loan
Documents as any other Lender and may exercise the same as though it were not
Agent; and the terms "Lender," "Lenders" or "Majority Lenders" shall, unless
otherwise expressly indicated, include Fleet in its individual capacity as a
Lender. Fleet and its Affiliates may lend money to, and generally engage in any
kind of business with, each Borrower, and any Person who may do business with or
own Securities of each Borrower all as if Fleet were not Agent and without any
duty to account therefor to any other Lender.

                  11.4.    Lender Credit Decision.

                  Each Lender acknowledges that it has, independently and
without reliance upon Agent or any other Lender and based on the financial
statements referred to herein and such other documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Lender also acknowledges that it will, independently and without
reliance upon Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement. Agent
shall not have any duty or responsibility, either initially or on an ongoing
basis, to provide any Lender with any credit or other similar information
regarding any Borrower.

                                      -70-

<PAGE>

                  11.5.    Indemnification.

                  Lenders agree to indemnify Agent and Arranger (to the extent
not reimbursed by Borrowers or Guarantors), in accordance with their respective
Aggregate Percentages, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or asserted against Agent or Arranger in any way relating to or arising out
of this Agreement or any other Loan Document or any action taken or omitted by
Agent or Arranger under this Agreement; provided that no Lender shall be liable
for any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting from
Agent's or Arranger's gross negligence or willful misconduct. Without limitation
of the foregoing, each Lender agrees to reimburse Agent and Arranger promptly
upon demand for its ratable share, as set forth above, of any out-of-pocket
expenses (including reasonable attorneys' fees) incurred by Agent or Arranger in
connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiation, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement and each other Loan Document, to the
extent that Agent or Arranger, as applicable, is not reimbursed for such
expenses by Borrowers. The obligations of Lenders under this Section 11.5 shall
survive the payment in full of all Obligations and the termination of this
Agreement. If after payment and distribution of any amount by Agent to Lenders,
any Lender or any other Person, including any Borrower, any creditor of any
Borrower, a liquidator, administrator or trustee in bankruptcy, recovers from
Agent or Arranger any amount found to have been wrongfully paid to Agent or
Arranger or disbursed by Agent or Arranger to Lenders, then Lenders, in
accordance with their respective Aggregate Percentages, shall reimburse Agent or
Arranger, as applicable, for all such amounts.

                  11.6.    Rights and Remedies to be Exercised by Agent Only.

                  Each Lender agrees that, except as set forth in Section 10.4,
no Lender shall have any right individually (i) to realize upon the security
created by this Agreement or any other Loan Document, (ii) to enforce any
provision of this Agreement or any other Loan Document, or (iii) to make demand
for payment by any Borrower under this Agreement or any other Loan Document.

                  11.7.    Agency Provisions Relating to Collateral.

                  Each Lender authorizes and ratifies Agent's entry into this
Agreement and the Security Documents for the benefit of Lenders. Each Lender
agrees that any action taken by Agent with respect to the Collateral in
accordance with the provisions of this Agreement or the Security Documents, and
the exercise by Agent of the powers set forth herein or therein, together with
such other powers as are reasonably incidental thereto, shall be authorized and
binding upon all Lenders. Agent is hereby authorized on behalf of all Lenders,
without the necessity of any notice to or further consent from any Lender to
take any action with respect to any Collateral or the Loan Documents which may
be necessary to perfect and maintain perfected Agent's Liens upon the
Collateral, for its benefit and the ratable benefit of Lenders.

                                      -71-

to release any Lien granted to or held by Agent upon any Collateral (i) upon
termination of the Agreement and payment and satisfaction of all Obligations; or
(ii) constituting property being sold or disposed of in compliance with
subsection 8.2.9 hereof and if Borrowers certify to Agent that the sale or
disposition is made in compliance with subsection 8.2.9 hereof, as it may be
amended from time to time in accordance with the provisions of Section 11.10
(and Agent may rely conclusively on any such certificate, without further
inquiry); or (iii) constituting property in which no Borrower owned any interest
at the time the Lien was granted or at any time thereafter; or (iv) in
connection with any foreclosure sale or other disposition of Collateral after
the occurrence and during the continuation of an Event of Default or (v) if
approved, authorized or ratified in writing by Agent at the direction of all
Lenders. Upon request by Agent at any time, Lenders will confirm in writing
Agent's authority to release particular types or items of Collateral pursuant
hereto. Agent shall have no obligation whatsoever to any Lender or to any other
Person to assure that the Collateral exists or is owned by any Borrower or is
cared for, protected or insured or has been encumbered or that the Liens granted
to Agent herein or pursuant to the Security Documents have been properly or
sufficiently or lawfully created, perfected, protected or enforced or are
entitled to any particular priority, or to exercise at all or in any particular
manner or under any duty of care, disclosure or fidelity, or to continue
exercising, any of its rights, authorities and powers granted or available to
Agent in this Section 11.7 or in any of the Loan Documents, it being understood
and agreed that in respect of the Collateral, or any act, omission or event
related thereto, Agent may act in any manner it may deem appropriate, in its
sole discretion, but consistent with the provisions of this Agreement, including
given Agent's own interest in the Collateral as a Lender and that Agent shall
have no duty or liability whatsoever to any Lender.

                  11.8.    Agent's Right to Purchase Commitments.

time upon written notice to any Lender and with the consent of such Lender,
which may be granted or withheld in such Lender's sole discretion, to purchase
for Agent's own account all of such Lender's interests in this Agreement, the
other Loan Documents and the Obligations, for the face amount of the outstanding
Obligations owed to such Lender, including without limitation all accrued and
unpaid interest and fees.

                  11.9.    Right of Sale, Assignment, Participations.

                  Each Borrower hereby consents to any Lender's participation,
sale, assignment, transfer or other disposition, at any time or times hereafter,

or thereof, including, without limitation, such Lender's rights, title,
interests, remedies, powers, and duties hereunder or thereunder subject to the

         "Lender" for all purposes of this Agreement and (y) the assigning
         Lender shall have no further liability for funding the portion of
         Revolving Loan Commitments assumed by such other Lender.

                  11.9.2.  Participations. Any Lender may grant participations
         in its extensions of credit hereunder to any other Lender or other
         lending institution (a "Participant"), provided that (i) no such
         participation shall be for an amount of less than $5,000,000 or any
         integral multiple of $1,000,000 in excess thereof, other than

         Default or Event of Default, (iv) no sale of a participation in
         extensions of credit shall in any manner relieve the originating Lender
         of its obligations hereunder, (v) the originating Lender shall remain

         Lender, Agent and Borrowers) to provide the transferor Lender, Agent

any other Loan Document (including without limitation any Note), nor consent to

(but shall not be required to), provide that only Lenders executing such
agreement by a specified date may share in such fee (and in such case, such fee
shall be divided among the applicable Lenders on a pro rata basis without

agreement).

                  11.11.   Resignation of Agent; Appointment of Successor.

         Agent by giving not less than thirty (30) days' prior written notice to
         Lenders and Borrowers. If Agent shall resign under this Agreement,
         then, (i) subject to the consent of Borrowers (which consent shall not
         be unreasonably withheld and which consent shall not be required during
         any period in which a Default or an Event of Default exists), Majority
         Lenders shall appoint from among Lenders and their Affiliates a
         successor agent for Lenders or (ii) if a successor agent shall not be
         so appointed and approved within the thirty (30) day period following
         Agent's notice to Lenders and Borrowers of its resignation, then Agent
         shall appoint a successor agent who shall serve as Agent until such
         time as Majority Lenders appoint a successor agent, subject to

         and the term "Agent" shall mean such successor effective upon its
         appointment, and the former Agent's rights, powers and duties as Agent
         shall be terminated without any other or further act or deed on the

                                      -75-

<PAGE>

         any Agent hereunder, the provisions of this Section 11 shall inure to
         the benefit of such former Agent and such former Agent shall not by
         reason of such resignation be deemed to be released from liability for
         any actions taken or not taken by it while it was an Agent under this
         Agreement.

                  11.11.2. Borrowers' Request. At any time after the second
         anniversary of the Closing Date, Borrowers may request that Fleet
         resign as Agent hereunder and that (i) Fleet transfer all of its
         interests in the Agreement and the Loan Documents to Bank and (ii)
         Majority Lenders appoint Bank as successor Agent hereunder. If Bank and
         Majority Lenders consent to the foregoing, in their reasonable
         judgment, such resignation, transfer and appointment will take place in
         the manner set forth in subsections 11.9.1 and 11.11.1 hereof.

                  11.12.   Audit and Examination Reports; Disclaimer by Lenders.

                  By signing this Agreement, each Lender:

         prepared by or on behalf of Agent;

                  (b)      expressly agrees and acknowledges that Agent (i) does
         not make any representation or warranty as to the accuracy of any
         Report, and (ii) shall not be liable for any information contained in
         any Report;

                  (c)      expressly agrees and acknowledges that the Reports
         are not comprehensive audits or examinations, that Agent or other party
         performing any audit or examination will inspect only specific
         information regarding each Borrower and will rely significantly upon
         each Borrower's books and records, as well as on representations of
         each Borrower's personnel;

                  (d) agrees to keep all Reports confidential and strictly for
         its internal use, and not to distribute except to its assignees or

an irrevocable power of attorney (fonde de pouvoir within the meaning of Article

         any amounts which Agent or any Lender may have paid for the account of
         any Borrower pursuant to any of the Loan Documents and which have not

         3750 as of 11:00 a.m. (London time) on the day that is two (2) London
         Banking Days preceding the first day of such Interest Period; provided,

         be the rate (rounded upwards as described above, if necessary) for
         deposits in U.S. dollars for a period substantially equal to the

         London Banking Days prior to the first day of such Interest Period. If
         both the Telerate and Reuters systems are unavailable, then the rate
         for that date will be determined on the basis of the offered rates for
         deposits in U.S. dollars for a period of time comparable to such
         Interest Period which are offered by four (4) major banks in the London
         interbank market at approximately 11:00 a.m. (London time), on the day

         each of the major London banks so selected will be requested to provide
         a quotation of its U.S. dollar deposit offered rate. If at least two
         (2) such quotations are provided, the rate for that date will be the
         arithmetic mean of the quotations. If fewer than two quotations are
         provided as requested, the rate for that date will be determined on the
         basis of the rates quoted for loans in U.S. dollars to leading European
         banks for a period of time comparable to such Interest Period offered
         by major banks in New York City at approximately 11:00 a.m. (New York
         City time), on the day that is two (2) London Banking Days preceding
         the first day of such Interest Period. In the event that Agent is
         unable to obtain any such quotation as provided above, it will be
         determined that LIBOR pursuant to a Interest Period cannot be
         determined. In the event that the Board of Governors of the Federal
         Reserve System shall impose a Reserve Percentage with respect to LIBOR
         deposits of Bank then for any period during which such Reserve
         Percentage shall apply, LIBOR shall be equal to the amount determined
         above divided by an amount equal to 1 minus the Reserve Percentage.
