         A. Borrowers, Agent and Lenders entered into that certain Revolving
Credit and Term Loan Agreement dated as of October 29, 1998, as amended as of
December 31, 1998, November 22, 1999 and June 28, 2001 ("Agreement").

         B. Borrowers have requested that Banks amend the Agreement as set forth

         C. The parties desire to amend the Agreement as set forth below.

         NOW, THEREFORE, the parties agree as follows:

         1. The definitions of "Borrowing Base", "CapEx Limit", "Excess Cash
Flow" and "Rollover Amount" set forth in Section 1 of the Agreement are amended
to read as follows:

         "'Borrowing Base' shall mean, as of any date of determination, an
         amount equal to the sum of (x) eighty percent (80%) of Eligible

         Inventory and (2) sixty percent (60%) of Eligible Accounts and (z) the

         "'CapEx Limit' shall mean (i) for fiscal year 2001, $750,000 (ii) for
         fiscal year 2002, $3,000,000 and (iii) for each subsequent fiscal year,
         $1,000,000."

         "'Excess Cash Flow' shall mean, as of the end of any fiscal year of
         Holdings, Consolidated Net Income for such fiscal year, plus, to the
         extent deducted in determining Consolidated Net Income, (i)
         depreciation, amortization and non-cash interest expense for such
         fiscal year and (ii) write-offs of good will and other non-cash events
         for such fiscal year, minus the sum of (i) reductions in the purchase
         accounting reserve from cash payments during such fiscal year, (ii)
         Capital Expenditures made by Holdings and its Consolidated Subsidiaries
         during such fiscal year (to the extent permitted under Section 9.7 of
         this Agreement) and any Rollover Amount for such period to be carried
         forward to the next period less the Rollover Amount, if any, for the
         preceding period carried forward to the current period that was not
         spent during such current period, provided however, for purposes of
         this clause (ii) only and notwithstanding the definition of "CapEx
         Limit" set forth in this Agreement, the CapEx Limit for fiscal year
         2002 shall be deemed to be $1,000,000, (iii) the amount of all payments
         of principal made on Senior Debt during such fiscal year (excluding any
         payments on Revolving Credit Advances and payments by Holdings and its
         Consolidated Subsidiaries under any other revolving credit facility to
         the extent the Revolving Credit Aggregate Commitment or availability
         under such other facility, as the case may be, is not permanently
         reduced in connection therewith), (iv) any non-cash credits included in
         determining Consolidated Net Income for such period, (v) non-cash gains
         from sales of assets included in Consolidated Net Income for such
         period, (vi) non-cash charges added back in a previous period to the
         extent any such charge has become a cash item in the current period,
         (vii) any cash disbursement to Sellers required pursuant to the Stock
         Purchase Agreement for purchase price adjustments or tax obligations,
         (viii) any cash disbursements made during such period against
         non-current liabilities to the extent not deducted in determining
         Consolidated Net Income, and (ix) any cash restructuring expenditures
         incurred during such period to the extent not deducted in determining
         Consolidated Net Income for such period and to the extent not exceeding
         $5,000,000."

         "'Rollover Amount' shall mean the aggregate amount of unutilized
         Capital Expenditures carried forward from one fiscal year to the next
         fiscal year to the extent permitted pursuant to the provisions of
         Section 9.7."

         2. Section 9.7 of the Agreement is amended to read as follows:

         "9.7 Limitation on Capital Expenditures. Make or commit to make (by way
         of the acquisition of securities of a Person or otherwise) any
         expenditure in respect of the purchase or other acquisition of fixed or
         capital assets (excluding any such asset acquired in connection with
         replacement and maintenance programs) except expenditures in the
         ordinary course of business not exceeding, in the aggregate for the
         Borrowers during any


                                       2
<PAGE>


         fiscal year, an amount equal to the CapEx Limit, determined on a
         non-cumulative basis in accordance with GAAP; except that the unused
         amount of the CapEx Limit in any fiscal year may be carried over and
         used in the next succeeding fiscal year, provided that there shall be
         no carry over of such unused amount in any subsequent year and provided
         further that for purposes of calculating the amount which may be
         carried over, all Capital Expenditures for a fiscal year shall be first
         applied to the CapEx Limit for such year."

         3. Except as expressly modified hereby, all the terms of and conditions
of the Agreement shall remain in full force and effect.

         4. Borrowers hereby represent and warrant that, AFTER GIVING EFFECT TO
THE AMENDMENTS CONTAINED HEREIN, (a) execution, delivery and performance of this
Amendment and any other documents and instruments required under this Amendment
or the Agreement are within each of the Borrowers' powers, have been duly
authorized, are not in contravention of law or the terms of each of the
Borrowers' Articles of Incorporation or Bylaws or Articles of Organization or
Operating Agreement, as applicable, and do not require the consent or approval
of any governmental body, agency, or authority; and this Amendment and any other
documents and instruments required under this Amendment or the Agreement, will
be valid and binding in accordance with their terms; (b) the representations and
warranties of Borrowers set forth in Sections 7.1 through 7.17 and 7.19 through
7.23 of the Agreement are true and correct in all material respects on and as of

no Event of Default, or condition or event which, with the giving of notice or
the running of time, or both, would constitute an Event of Default under the
Agreement, has occurred and is continuing as of the date hereof.

         4. This Amendment may be signed in any number of counterparts, each of
which when so executed and delivered shall be deemed an original, but all such
counterparts together shall constitute but one and the same instrument.
