            Subject to the terms and conditions of this Agreement and the
            other Loan Documents, and in reliance upon the representations
            and warranties of Borrower set forth herein and in the other
            Loan Documents, the Bank agrees to make such Revolving Loans at
            such times as Borrower may from time to time request until, but
            not including, the Maturity Date, and in such amounts as
            Borrower may from time to time request; provided, however, that
            the aggregate principal balance of all Revolving Loans and all
            Letter of Credit Obligations (the "Outstandings") outstanding
            at any time shall not exceed (i) the Revolving Loan Commitment

as follows:

            (i)   MANDATORY PREPAYMENTS.  All Revolving Loans hereunder
            shall be repaid by Borrower on the Maturity Date, unless
            payable sooner pursuant to the provisions of this Agreement.
            In the event the aggregate outstanding principal balance of all
            Revolving Loans and Letter of Credit Obligations hereunder
            exceeds (i) the Revolving Loan Commitment (in the event the
            aggregate amount of outstanding Revolving Loans and the stated
            amount of all Letters of Credit are less than or equal to
            $20,000,000) or (ii) Revolving Loan Availability (in the event
            the aggregate amount of outstanding Revolving Loans and the
            stated amount of all Letters of Credit are greater than

            kind, immediately make such repayments of the Revolving Loans

            Revolving Loan which is a LIBOR Loan to a Prime Loan as
            provided in Section 2.2(b) and Section 2.2(c), then such
            Revolving Loan shall be immediately due and payable on the last
            New York Banking Day of the then-existing Loan Period or on
            such earlier date as required by law, all without further
            demand, presentment, protest or notice of any kind, all of
            which are hereby waived by Borrower (each a "Mandatory
            Prepayment").

            (f)   SECTION 5.1(a) is hereby amended and restated to read as
follows:

            (a)   Each Loan shall be made available to Borrower upon
            Borrower's request from any Person whose authority to so act
            has not been revoked by Borrower in writing previously received
            by the Bank.  Each Revolving Loan may be advanced either as a
            Prime Loan (to the extent available in accordance with the
            terms herein) or a LIBOR Loan.  A request for a Prime Loan must
            be received by no later than 11:00 a.m. Chicago, Illinois time,
            on the day it is to be funded.  A request for a LIBOR Loan must
            be received by no later than 11:00 a.m. Chicago, Illinois time
            on the day it is to be funded.  In the event Borrower does not
            select an interest rate option, such Loan shall bear interest
            at the LIBOR Rate.  The proceeds of each Prime Loan or LIBOR
            Loan shall be made available at the office of the Bank by
            credit to the account of Borrower or by other means requested
            by Borrower and acceptable to the Bank.  All Loans must be paid
            in full on the Maturity Date.  Bank's internal records of
            applicable interest rates shall be determinative in the absence
            of manifest error.

            (g)   SECTION 5.2 of the Agreement is hereby amended by
removing the words "one percent (1.00%)" appearing in the middle of such

(1.90%)" in their place.

            in excess of $10,000,000 and the aggregate amount of all
            Outstandings is greater than or equal to $20,000,000 after
            giving effect to all requests for Revolving Loans, the Borrower
            shall provide the Bank with a Borrowing Base Certificate
            immediately prior to such Acquisition evidencing that the
            Outstandings (including the requested advance) do not exceed

            otherwise available), the terms and conditions, including
            economic terms, of the proposed Acquisition, and Borrower's
