(2) The parties hereto desire to modify certain terms and provisions of the Credit Agreement, all as more fully set forth below. NOW, THEREFORE, the parties hereby agree as follows: Section 1. Amendments and Consents. 1.1. Amended Definition. Section 1.1 of the Credit Agreement is hereby amended to delete the definition of "CONSOLIDATED EBITDA" therefrom and to insert in place thereof the following: "CONSOLIDATED EBITDA" shall mean, for any period, Consolidated EBIT for such period; PLUS the sum (without duplication) of the amounts for such period included in determining such Consolidated EBIT of (i) Consolidated Depreciation Expense, (ii) Consolidated Amortization Expense, (iii) not more than $8,000,000 of Consolidated Obsolescence Expense, (iv) if such period includes any portion of the last fiscal quarter of 1997 or any fiscal quarter of 1998, the restructuring charges (including restructuring reserves) taken during the fourth quarter of 1997 and the second quarter of 1998, as well as other restructuring charges and reserves (including MARTA) incurred during the third and fourth quarters of 1998 up to an aggregate of not more than $13,000,000, and (v) restructuring charges related to the acquisition of the Person identified by the Borrower in the materials distributed to the Lenders on November 7, 2001 taken during the fourth 1 quarter of 2001 or during the 2002 fiscal year, so long as the aggregate amount of all such charges shall not exceed $2,000,000, all as determined for the Borrower and its Subsidiaries on a consolidated basis in accordance with GAAP; PROVIDED that, notwithstanding anything to the contrary contained herein, the Borrower's Consolidated EBITDA for any Testing Period shall (x) include the appropriate financial items for any person or business unit which has been acquired by the Borrower and its Subsidiaries for any portion of such Testing Period prior to the date of acquisition, and (y) exclude the appropriate financial items for any person or business unit which has been disposed of by the Borrower and its Subsidiaries, for the portion of such Testing Period prior to the date of disposition. 1.2. CONSENT TO PAYMENT OF INDEBTEDNESS IN CONNECTION WITH ACQUISITION. The Borrower has notified the Administrative Agent and the Lenders that the Borrower intends to purchase substantially all of the assets of the Person (the "SELLER") identified by the Borrower in the materials distributed to the Lenders on November 7, 2001 (the "PROPOSED ACQUISITION"), on a non-cash basis with the purchase price to be paid with stock of the Borrower and without the raising of the additional equity originally contemplated in the materials distributed to the Lenders on September 19, 2001. The Proposed Acquisition on a non-cash basis is permitted by Section 9.2(c) of the Credit Agreement, except that, in connection with the Proposed Acquisition, the Borrower is proposing to assume or repay a limited amount of Indebtedness of the Seller and pay off a line of credit owing by the Seller in order to release the lien of the lender under such line of credit on the inventory, accounts receivable and other assets being sold in the Proposed Acquisition (collectively, the "ACQUISITION DEBT"). The Borrower has requested that the Administrative Agent and the Lenders consent to the Borrower assuming or repaying the Acquisition Debt. The Administrative Agent and the Lenders hereby consent to the Borrower's assumption or repayment of the Acquisition Debt, and this Amendment shall serve as evidence of such consent, on the conditions that (a) the aggregate amount of Acquisition Debt assumed or repaid shall not exceed $5,000,000, (b) the Borrower shall provide the Administrative Agent with evidence, in form and substance satisfactory to the Administrative Agent, that all liens on the assets being sold in the Proposed Acquisition have been released concurrently with the Proposed Acquisition, and (c) no Default or Event of Default shall exist or immediately after the Proposed Acquisition shall begin to exist. In addition, the Borrower, the Administrative Agent and the Lenders hereby acknowledge that, since the Borrower is effecting the Proposed Acquisition without the raising of equity as contemplated in the materials distributed to the Lenders on September 19, 2001, the Borrower did not effect the Target Acquisition, and, as a result thereof, the Adjusted Covenant Date did not and will not occur.

This Amendment has been duly authorized by all necessary corporate action on the part of the Borrower, has been duly executed and delivered by a duly authorized officer of the Borrower, and constitutes the valid and binding agreement of the Borrower, enforceable against the Borrower in accordance with its terms. 2 2.2.
