<PAGE>   3
         SUBPART 2. Amendments to Section 2.1. Subsection (a) of Section 2.1 of
the Existing Credit Agreement is hereby amended in its entirety to read as
follows:

                  (a)    Revolving Commitment. Subject to the terms and 
         conditions hereof and in reliance upon the representations and
         warranties set forth herein, each Lender severally agrees to make
         available to the Borrower such Lender's Revolving Commitment Percentage
         of revolving credit loans in Dollars ("Revolving Loans") from time to
         time from the Effective Date until the Termination Date, or such
         earlier date as the Revolving Commitments shall have been terminated as
         provided herein for the purposes hereinafter set forth; provided,
         however, that the sum of the aggregate principal amount of outstanding
         Revolving Loans shall not exceed the lesser of (a) FORTY MILLION
         DOLLARS ($40,000,000.00) (as such aggregate maximum amount may be
         reduced from time to time as provided in Section 3.4(a), the "Revolving
         Committed Amount") and (b) the Borrowing Base; provided, further, (i)
         with regard to each Lender individually, such Lender's outstanding
         Revolving Loans shall not exceed such Lender's Revolving Commitment
         Percentage of the Revolving Committed Amount, and (ii) with regard to
         the Lenders collectively, the aggregate principal amount of outstanding
         Revolving Loans plus the Dollar Amount (as determined as of the most
         recent Determination Date) of the aggregate principal amount of
         outstanding Foreign Currency Loans plus the aggregate principal amount
         of outstanding Swingline Loans plus LOC Obligations outstanding shall
         not exceed the lesser of (A) the Revolving Committed Amount and (B) the
         Borrowing Base. Revolving Loans may consist of Base Rate Loans or
         Eurodollar Loans, or a combination thereof, as the Borrower may
         request, and may be repaid and reborrowed in accordance with the
         provisions hereof; provided, however, that (x) during the Initial
         Interest Rate Period, all Eurodollar Loans shall have an Interest
         Period of one (1) month and (y) no more than 10 Eurodollar Loans shall
         be outstanding hereunder at any time. For purposes hereof, Eurodollar
         Loans with different Interest Periods and/or in different currencies
         shall be considered as separate Eurodollar Loans, even if they begin on
         the same date, although borrowings, extensions and conversions may, in
         accordance with the provisions hereof, be combined at the end of
         existing Interest Periods to constitute a new Eurodollar Loan with a
         single Interest Period and in the same currency. Revolving Loans
         hereunder may be repaid and reborrowed in accordance with the
         provisions hereof.

         SUBPART 2.2 Replacement of Schedule 2.1(a). Schedule 2.1(a) to the
Existing Credit Agreement is hereby deleted in its entirety and a new schedule
in the form of Schedule 2.1(a) attached hereto is substituted therefor.
