     (c) Article II of the Credit Agreement shall be amended in its entirety and

     2.1 COMMITMENT. From and including the date of this Agreement and prior to
the Facility Termination Date, each Lender severally agrees, on the terms and
conditions set forth in


<PAGE>


this Agreement, to make Loans to the Borrower from time to time in amounts not
to exceed in the aggregate at any one time outstanding its Pro Rata Share of the
Available Aggregate Commitment, PROVIDED that at no time shall the Aggregate
Outstanding Credit Exposure hereunder exceed the Borrowing Base as then
determined and computed. Subject to the terms of this Agreement, the Borrower
may borrow, repay and reborrow at any time prior to the Facility Termination
Date. The Commitments to lend hereunder shall expire on the Facility Termination
Date.

     2.2 REQUIRED PAYMENTS; TERMINATION. Any outstanding Advances and all other
unpaid Obligations shall be paid in full by the Borrower on the Facility
Termination Date. Additionally, if on any day the Aggregate Outstanding Credit
Exposure exceeds the lesser of (a) the Borrowing Base or (b) the Aggregate
Commitment, the Borrower shall immediately make a prepayment of the Loans in an
amount sufficient to eliminate such excess. Additionally, the Borrower shall,
from time to time, immediately prepay the Loans and the Aggregate Commitment
shall automatically reduce (subject to re-instatement upon request of the
Borrower and consent to do so by all the Lenders) in an amount equal to all
income tax refunds received by the Borrower. Additionally, the Borrower shall,
from time to time, immediately prepay the Loans in an amount equal to the net
proceeds received on account of the sale of any of its assets, including,
without limitation, any sale of Collateral.

     2.3 RATABLE LOANS. Each Advance hereunder (other than any Swing Line Loan)
shall consist of Revolving Loans made from the several Lenders ratably in
proportion to the ratio that their respective Commitments bear to the Aggregate
Commitment.

     2.4 TYPES OF ADVANCES. The Advances may be Floating Rate Advances, selected
by the Borrower in accordance with Section 2.9, or, in the discretion of the
Swing Lender, Swing Line Loans selected by the Borrower in accordance with
Section 2.5.

     2.5 SWING LINE LOANS.

          2.5.1. AMOUNT OF SWING LINE LOANS. Upon the satisfaction of the
     conditions precedent set forth in Section 4.2, from time to time prior to
     the Facility Termination Date, the Swing Line Lender may in its discretion
     but only with the prior approval of all Lenders, on the terms and
     conditions set forth in this Agreement, make Swing Line Loans to the
     Borrower from time to time in an aggregate principal amount not to exceed
     the Swing Line Commitment, PROVIDED that the Aggregate Outstanding Credit
     Exposure shall not at any time exceed the lesser of (a) Aggregate
     Commitment or (b) the Borrowing Base, and PROVIDED FURTHER that at no time
     shall the sum of (i) the Swing Line Lender's Pro Rata Share of the Swing
     Line Loans, PLUS (ii) the outstanding Revolving Loans made by the Swing
     Line Lender pursuant to Section 2.1, exceed the Swing Line Lender's
     Commitment at such time. Subject to the terms of this Agreement, the
     Borrower may borrow, repay and reborrow Swing Line Loans at any time prior
     to the Facility Termination Date.

<PAGE>

          2.5.2. BORROWING NOTICE. The Borrower shall deliver to the Agent and
     the Swing Line Lender irrevocable notice (a "Swing Line Borrowing Notice")
     not later than noon (Chicago time) on the Borrowing Date of each Swing Line
     Loan, specifying the applicable Borrowing Date (which date shall be a
     Business Day), and the aggregate amount of the requested Swing Line Loan.
     The Swing Line Loans shall bear interest at the Floating Rate.

          2.5.3. MAKING OF SWING LINE LOANS. Not later than 2:00 p.m. (Chicago
     time) on the applicable Borrowing Date, the Swing Line Lender shall advise
     the Borrower if it has received the approval of the Lenders to make the
     requested Swing Line Loan and if it is willing to make such Swing Line Loan
     and if so, the Swing Line Lender shall make available the Swing Line Loan,
     in funds immediately available in Chicago, to the Agent at its address
     specified pursuant to Article XIII. In the event the Swing Line Lender
     shall fail to respond to any request by the Borrower for a Swing Line Loan,
     such request shall be deemed denied. The Agent will promptly make the funds
     so received from the Swing Line Lender available to the Borrower on the
     Borrowing Date at the Agent's aforesaid address.

          2.5.4. REPAYMENT OF SWING LINE LOANS. Each Swing Line Loan shall be
     paid in full by the Borrower on demand by the Swing Line Lender to do so
     but in no event later than the Facility Termination Date. In addition, the
     Swing Line Lender may at any time in its sole discretion with respect to
     any outstanding Swing Line Loan, require each Lender (including the Swing
     Line Lender) to make a Revolving Loan in the amount of such Lender's Pro
     Rata Share of such Swing Line Loan, for the purpose of repaying such Swing
     Line Loan. Not later than noon (Chicago time) on the date of any notice
     received pursuant to this Section 2.5.4, each Lender shall make available
     its required Revolving Loan, in funds immediately available in Chicago to
     the Agent at its address specified pursuant to Article XIII. Revolving
     Loans made pursuant to this Section 2.5.4 shall be Floating Rate Loans.
     Unless a Lender shall have notified the Swing Line Lender, prior to its
     making any Swing Line Loan, that any applicable condition precedent set
     forth in Section 4.1 had not then been satisfied, such Lender's obligation
     to make Revolving Loans pursuant to this Section 2.5.4 to repay Swing Line
     Loans shall be unconditional, continuing, irrevocable and absolute and
     shall not be affected by any circumstances, including, without limitation,
     (a) any set-off, counterclaim, recoupment, defense or other right which
     such Lender may have against the Agent, the Swing Line Lender or any other
     Person, (b) the occurrence or continuance of a Default or Unmatured
     Default, (c) any adverse change in the condition (financial or otherwise)
     of the Borrower, or (d) any other circumstances, happening or event
     whatsoever. In the event that any Lender fails to make payment to the Agent
     of any amount due under this Section 2.5.4, the Agent shall be entitled to
     receive, retain and apply against such obligation the principal and
     interest otherwise payable to such Lender hereunder until the Agent
     receives such payment from such Lender or such obligation is otherwise
     fully satisfied. In addition to the foregoing, if for any reason any Lender
     fails to make payment to the Agent of any amount due under this Section
     2.5.4, such Lender shall be deemed, at the option of the Agent, to have

<PAGE>


     unconditionally and irrevocably purchased from the Swing Line Lender,
     without recourse or warranty, an undivided interest and participation in
     the applicable Swing Line Loan in the amount of such Revolving Loan, and
     such interest and participation may be recovered from such Lender together
     with interest thereon at the Federal Funds Effective Rate for each day
     during the period commencing on the date of demand and ending on the date
     such amount is received. On the Facility Termination Date, the Borrower
     shall repay in full the outstanding principal balance of the Swing Line
     Loans.

     2.6 COMMITMENT FEE; REDUCTIONS IN AGGREGATE COMMITMENT; AMENDMENT FEE. The
Borrower agrees to pay to the Agent for the account of each Lender a commitment
fee at a per annum rate equal to one-half of one percent (1/2%) on the daily
unused portion of such Lender's Commitment from the date hereof to and including
the Termination Date, payable on each Payment Date hereafter and on the Facility
Termination Date. Swing Line Loans shall not count as usage of any Lender's
Commitment for the purpose of calculating the commitment fee due hereunder. The
Borrower may permanently reduce the Aggregate Commitment in whole, or in part
ratably among the Lenders in integral multiples of $1,000,000, upon at least one
(1) Business Day's written notice to the Agent, which notice shall specify the
amount of any such reduction, PROVIDED, HOWEVER, that the amount of the
Aggregate Commitment may not be reduced below the aggregate principal amount of
the outstanding Advances. All accrued commitment fees shall be payable on the
effective date of any termination of the obligations of the Lenders to make
Loans hereunder.

     (b) The Borrower agrees to pay to the Agent for the account of the Lenders
a sixth amendment fee in an amount equal to 1% of the aggregate Commitments in
effect as of August 31, 2000, such fee to be fully earned upon execution of the
Sixth Amendment to Credit Agreement by the Borrower and Lenders and delivery of
the same to the Agent and to be payable upon the earlier of (a) payment of the
Obligations in full and termination of the Commitments, (b) December 31, 2000 or
(c) acceleration of the Obligations pursuant to Section 8.1 hereof.

     2.7 INTEREST OPTIONS. No Advance may be made as, converted into or
continued as a Eurodollar Advance.

     2.8 OPTIONAL PRINCIPAL PAYMENTS. The Borrower may from time to time pay,
without penalty or premium, all outstanding Floating Rate Advances or any
portion of the outstanding Floating Rate Advances upon notice to Agent, or the
Swing Line Lender as the case may be, by 11:00 a.m. (Chicago time) on the date
of repayment.

     2.9 METHOD OF SELECTING TYPES AND INTEREST PERIODS FOR NEW ADVANCES. The
Borrower shall select the Type of Advance from time to time. The Borrower shall
give the Agent irrevocable notice (a "Borrowing Notice") not later than 10:00
a.m. (Chicago time) on the Borrowing Date of each Floating Rate Advance (other
than a Swing Line Loan) specifying:

     (i) the Borrowing Date, which shall be a Business Day, of such Advance, and

<PAGE>

     (ii) the aggregate amount of such Advance.

Not later than noon (Chicago time) on each Borrowing Date, each Lender shall
make available its Revolving Loan or Revolving Loans in funds immediately
available in Chicago to the Agent at its address specified pursuant to Article
XIII. The Agent will make the funds so received from the Lenders available to
the Borrower at the Agent's aforesaid address.

     2.10 CONTINUATION OF OUTSTANDING ADVANCES. Floating Rate Advances shall
continue as Floating Rate Advances unless and until such Floating Rate Advances
are repaid in accordance with Section 2.8.

     2.11 CHANGES IN INTEREST RATE, ETC. Each Floating Rate Advance (including
each Swing Line Loan) shall bear interest on the outstanding principal amount
thereof, for each day from and including the date such Advance is made, to but
excluding the date it is paid, at a rate per annum equal to the Floating Rate
for such day. Changes in the rate of interest on that portion of any Advance
maintained as a Floating Rate Advance will take effect simultaneously with each
change in the Alternate Base Rate.

     2.12 RATES APPLICABLE AFTER DEFAULT AND UNDER OTHER CIRCUMSTANCES.
Notwithstanding anything to the contrary contained in Section 2.9 or 2.10,
during the continuance of a Default or Unmatured Default the Required Lenders
may, at their option, by notice to the Borrower (which notice may be revoked at
the option of the Required Lenders notwithstanding any provision of Section 8.2
requiring unanimous consent of the Lenders to changes in interest rates),
declare that each Floating Rate Advance shall bear interest at a rate per annum
equal to the Floating Rate in effect from time to time plus 2% per annum,
PROVIDED that, during the continuance of a Default under Section 7.6 or 7.7,
such interest rate shall be applicable to all Advances without any election or
action on the part of the Agent or any Lender.

     2.13 METHOD OF PAYMENT. All payments of the Obligations hereunder shall be
made, without setoff, deduction, or counterclaim, in immediately available funds
to the Agent at the Agent's address specified pursuant to Article XIII, or at
any other Lending Installation of the Agent specified in writing by the Agent to
the Borrower, by noon (local time) on the date when due and shall (except with
respect to repayments of Swing Line Loans) be applied ratably by the Agent among
the Lenders. Each payment delivered to the Agent for the account of any Lender
shall be delivered promptly by the Agent to such Lender in the same type of
funds that the Agent received at its address specified pursuant to Article XIII
or at any Lending Installation specified in a notice received by the Agent from
such Lender. The Agent is hereby authorized to charge the account of the
Borrower maintained with ANB for each payment of principal, interest and fees as
it becomes due hereunder.

     2.14 NOTELESS AGREEMENT; EVIDENCE OF INDEBTEDNESS. (i) Each Lender shall
maintain in accordance with its usual practice an account or accounts evidencing
the indebtedness of the Borrower to such Lender resulting from each Loan made by
such Lender from time to time, including the amounts of principal and interest
payable and paid to such Lender from time to


<PAGE>


time hereunder.

     (ii) The Agent shall also maintain accounts in which it will record (a) the
amount of each Loan made hereunder and the Type thereof, (b) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (c) the amount of any sum received by the
Agent hereunder from the Borrower and each Lender's share thereof.

     (iii) The entries maintained in the accounts maintained pursuant to
paragraphs (i) and (ii) above shall be PRIMA FACIE evidence of the existence and
amounts of the Obligations therein recorded absent demonstrable or manifest
error; PROVIDED, HOWEVER, that the failure of the Agent or any Lender to
maintain such accounts or any error therein shall not in any manner affect the
obligation of the Borrower to repay the Obligations in accordance with their
terms.

     (iv) Any Lender may request that its Loans be evidenced by a promissory
note or, in the case of the Swing Line Lender, promissory notes representing its
Revolving Loans and Swing Line Loans, respectively, substantially in the form of
Exhibit E, with appropriate changes for notes evidencing Swing Line Loans (each
a "Note"). In such event, the Borrower shall prepare, execute and deliver to
such Lender such Note or Notes payable to the order of such Lender. Thereafter,
the Loans evidenced by each such Note and interest thereon shall at all times
(including after any assignment pursuant to Section 12.3) be represented by one
or more Notes payable to the order of the payee named therein or any assignee
pursuant to Section 12.3, except to the extent that any such Lender or assignee
subsequently returns any such Note for cancellation and requests that such Loans
once again be evidenced as described in paragraphs (i) and (ii) above.

     2.15. TELEPHONIC NOTICES. The Borrower hereby authorizes the Lenders and
the Agent to extend or continue Advances, effect selections of Types of Advances
and to transfer funds based on telephonic notices made by any person or persons
the Agent or any Lender in good faith believes to be acting on behalf of the
Borrower, it being understood that the foregoing authorization is specifically
intended to allow Borrowing Notices to be given telephonically. The Borrower
agrees to deliver promptly to the Agent a written confirmation, if such
confirmation is requested by the Agent or any Lender, of each telephonic notice
signed by an Authorized Officer. If the written confirmation differs in any
material respect from the action taken by the Agent and the Lenders, the records
of the Agent and the Lenders shall govern absent manifest or demonstrable error.

     2.16. INTEREST PAYMENT DATES; INTEREST AND FEE BASIS. Interest accrued on
each Floating Rate Advance shall be payable on each Payment Date, commencing
with the first such date to occur after the date hereof and at maturity.
Interest and commitment fees shall be calculated for actual days elapsed on the
basis of a 360-day year. Interest shall be payable for the day an Advance is
made but not for the day of any payment on the amount paid if payment is
received prior to 1:00 p.m. (local time) at the place of payment. If any payment
of principal of or interest on an Advance shall become due on a day which is not
a Business Day, such payment shall be

<PAGE>


made on the next succeeding Business Day and, in the case of a principal
payment, such extension of time shall be included in computing interest in
connection with such payment.

     2.17. NOTIFICATION OF ADVANCES, INTEREST RATES, PREPAYMENTS AND COMMITMENT
REDUCTIONS. Promptly after receipt thereof, the Agent will notify each Lender of
the contents of each Aggregate Commitment reduction notice, Borrowing Notice,
Swing Line Borrowing Notice, and repayment notice received by it hereunder. The
Agent will give each Lender prompt notice of each change in the Alternate Base
Rate.

     2.18 LENDING INSTALLATIONS. Each Lender may book its Loans at any Lending
Installation selected by such Lender and may change its Lending Installation
from time to time. All terms of this Agreement shall apply to any such Lending
Installation and the Loans and any Notes issued hereunder shall be deemed held
by each Lender for the benefit of any such Lending Installation. Each Lender
may, by written notice to the Agent and the Borrower in accordance with Article
XIII, designate replacement or additional Lending Installations through which
Loans will be made by it and for whose account Loan payments are to be made.

     2.19 NON-RECEIPT OF FUNDS BY THE AGENT. Unless the Borrower or a Lender, as
the case may be, notifies the Agent prior to the date on which it is scheduled
to make payment to the Agent of (i) in the case of a Lender, the proceeds of a
Loan or (ii) in the case of the Borrower, a payment of principal, interest or
fees to the Agent for the account of the Lenders, that it does not intend to
make such payment, the Agent may assume that such payment has been made. The
Agent may, but shall not be obligated to, make the amount of such payment
available to the intended recipient in reliance upon such assumption. If such
Lender or the Borrower, as the case may be, has not in fact made such payment to
the Agent, the recipient of such payment shall, on demand by the Agent, repay to
the Agent the amount so made available together with interest thereon in respect
of each day during the period commencing on the date such amount was so made
available by the Agent until the date the Agent recovers such amount at a rate
per annum equal to (x) in the case of payment by a Lender, the Federal Funds
Effective Rate for such day for the first three days and, thereafter, the
interest rate applicable to the relevant Loan or (y) in the case of payment by
the Borrower, the interest rate applicable to the relevant Loan.

     2.20 DISBURSEMENTS OF ADVANCES; SETTLEMENTS AMONG AGENT AND LENDERS;
PAYMENTS OF INTEREST AND FEES; DISGORGEMENT OBLIGATIONS . (a) The outstanding
balance of Advances may fluctuate from day to day through the Agent's
disbursement of funds to, and receipt of funds from, the Borrower. In order to
minimize the frequency of transfers of funds between the Agent and each Lender,
Advances and payments will be settled according to the procedures described in
this Section 2.20. Notwithstanding these procedures, each Lender's obligation to
fund its portion of any Advances made by the Agent to the Borrower will commence
on the date such Advances are made by the Agent. Such payments will be made by
each Lender without setoff, counterclaim or reduction of any kind.

         (b) On Friday of each week, or more frequently (including daily) if the
Agent so elects (each such day being a "Settlement Date"), the Agent will advise
each Lender by


<PAGE>

telephone or telecopy of the amount of each such Lender's ratable share of the
outstanding balance of Advance as of the close of business of the Business Day
immediately preceding the Settlement Date. In the event that payments are
necessary to adjust the amount of such Lender's share of the outstanding balance
of Advances to equal such Lender's Commitment percentage of the Obligations as
of any Settlement Date, such Lender will pay to the Agent, or the Agent will pay
to such Lender (as applicable) the amount necessary in same day funds by wire
transfer to the other's account not later than 4:00 p.m. Chicago time on the
Business Day following the Settlement Date.

     (c) Notwithstanding the foregoing, the Agent, at its option, may elect to
require that each Lender provide funds in connection with any requested
borrowing hereunder on the scheduled borrowing date, and in such event the Agent
shall advise each Lender by telephone or telecopy of the amount to be funded by
such Lender no later than the borrowing date applicable thereto, and each such
Lender shall pay to the Agent such Lender's Commitment percentage of the
borrowing in same day funds by wire transfer to the Agent's account not later
than 4:00 p.m. Chicago time on such Borrowing date.

     (d) On the first Business Day of each month (each, an "Interest Settlement
Date"), the Agent will advise each Lender by telephone or telecopy of the amount
of such Lender's commitment percentage of interest and fees on each Loan as of
the end of the last day of the immediately preceding month. Provided that such
Lender has made all payments required to be made by it under this Agreement, the
Agent will pay to such Lender, by wire transfer to such Lender's account (as
specified by such Lender on the signature page of this Agreement or the
applicable Assignment and Acceptance) not later than 2:00 p.m. Chicago time on
the next Business Day following the Interest Settlement Date, such Lender's
commitment percentage of interest and commitment fees, in each instance,
received by Agent in the immediately preceding month.

     (e) Unless the Agent shall have received notice from the Borrower prior to
the date on which any payment is due to the Lenders hereunder that the Borrower
will not make such payment in full as and when required hereunder, the Agent may
assume that the Borrower has made such payment in full to the Agent on such date
in immediately available funds and the Agent may (but shall not be so required),
in reliance upon such assumption, cause to be distributed to each Lender on such
due date an amount equal to the amount then due such Lender. If the Agent pays
an amount to a Lender under this Agreement in the belief or expectation that a
related payment has been or will be received by the Agent from the Borrower and
such related payment is not received by the Agent, the Agent shall be entitled
to recover such amount from such Lender, and each Lender shall repay to Agent on
demand such amount, together with interest thereon for each day from the date
such amount is distributed to such Lender until the date such Lender repays such
amount to the Agent, at the Agent's cost of funds, without setoff, counterclaim
or deduction of any kind. If the Agent determines at any time that any amount
received by the Agent under this Agreement must be returned to the Borrower or
paid to any other Person pursuant to any solvency, fraudulent conveyance or
similar law or otherwise, then, notwithstanding any other term or condition of
this Agreement, the Agent will


<PAGE>


not be required to distribute any portion of such payment to any Lender. In
addition, each Lender will repay to the Agent on demand any portion of such
amount that the Agent has distributed to such Lender, together with interest
thereon at such rate, if any, as the Agent is required to pay to the Borrower or
such other Person, without setoff, counterclaim or deduction of any kind.

(d)  Section 4.2 shall be amended in its entirety and as so amended shall read
     as follows:

     "4.2. EACH ADVANCE. The Lenders shall (except as otherwise set forth in
Section 2.5.4 with respect to Revolving Loans for the purpose of repaying Swing
Line Loans) not be required to make any Advance (other than an Advance that,
after giving effect thereto and to the application of the proceeds thereof, does
not increase the aggregate amount of outstanding Advances), unless on the
applicable Borrowing Date:

(i)   There exists no Default or Unmatured Default.

(ii)  The representations and warranties contained in Article V are true and
      correct as of such Borrowing Date except to the extent any such
      representation or warranty is stated to relate solely to an earlier date,
      in which case such representation or warranty shall have been true and
      correct on and as of such earlier date.

(iii) All legal matters incident to the making of such Advance shall be
      reasonably satisfactory to the Lenders and their counsel.

     Each Borrowing Notice or Swing Line Borrowing Notice, as the case may be,
with respect to each such Advance shall constitute a representation and warranty
by the Borrower that the conditions contained in Sections 4.2(i) and (ii) have
been satisfied."

     (e) Section 6.1 of the Credit Agreement shall be amended in its entirety
and as so amended shall read as follows:

     "6.1 FINANCIAL REPORTING. The Borrower will maintain, for itself and each
Subsidiary, a system of accounting established and administered in accordance
with generally accepted accounting principles, and furnish to the Lenders:

(i)  Within 120 days after the close of each of its fiscal years, an unqualified
     audit report certified by independent certified public accountants
     acceptable to the Lenders, prepared in accordance with Agreement Accounting
     Principles on a consolidated basis for itself and its Subsidiaries,
     including balance sheets as of the end of such period, related profit and
     loss and reconciliation of surplus statements, and a statement of cash
     flows, accompanied by any management letter prepared by said accountants.

         such Guarantor on account of Accounts Receivable in the identical form
         in which such payments were received, whether by cash or check or

         Subsidiary, any shareholder, officer, director, employee or agent of
         Borrower, any Guarantor or any Affiliate or Subsidiary, or any other
         Person acting for or in concert with Borrower or any Guarantor shall

         Borrower or applicable Guarantor to Agent, and, if that endorsement of
         any such item shall not be made for any reason, Agent is hereby

         Guarantor's behalf. For the purpose of this paragraph, Borrower
         irrevocably hereby makes, constitutes and appoints Agent (and all
         Persons designated by Agent for that purpose) as Borrower's true and
         lawful attorney and agent-in-fact (i) to endorse Borrower's name upon

         Chicago, Illinois of checks and (ii) on the Business Day of receipt by

               previously been reimbursed for such costs and expenses by the
               Lenders, in which event such amounts shall be remitted to the
               Lenders to reimburse them for payments theretofore made to the
               Agent);

                    (ii) second, to the payment of any outstanding interest or
