         The Borrowers and Lender are parties to that certain Third Amended and
Restated Revolving Credit and Security Agreement dated January 24, 2003 (as
amended, restated, supplemented or otherwise modified from time to time, the
"Loan Agreement") pursuant to which Lender provides the Borrowers with certain
financial accommodations.

         The Borrowers have violated certain covenants and have requested Lender
waive the resulting Events of Default and Lender is willing to do so.

         NOW, THEREFORE, in consideration of any loan or advance or grant of
credit heretofore or hereafter made to or for the account of Borrowers by
Lender, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

1. Definitions. All capitalized terms not otherwise defined or amended herein
shall have the meanings given to them in the Loan Agreement.

2. Waiver. Subject to the satisfaction of Section 3 below, Lender hereby waives
the Event of Default which has occurred as a result Borrowers' non-compliance
with Section 12(r) due to Borrowers' failure to achieve EBITDA for October, 2004
and December, 2004 at the requisite level for each such month. Notwithstanding
the foregoing, the waiver of the Events of Default set forth above does not
establish a course of conduct between Borrowers and Lender and Borrowers hereby
agree that Lender is not obligated to waive any future Events of Default under
the Loan Agreement.

3. Conditions of Effectiveness. This Waiver shall become effective as of the
date hereof, provided that Lender shall have received four (4) copies of this
Waiver executed by the Borrowers and the limited guarantors (each a "Limited
Guarantor") and the guarantor ("Guarantor") listed on the signature page hereto.

         (b) Upon the effectiveness of this Waiver, each of the Borrowers hereby
reaffirms all covenants, representations and warranties made in the Loan
Agreement to the extent the same are not amended hereby and agrees that all such

connection therewith, shall remain in full force and effect, and are hereby
ratified and confirmed.

         (b) Except as set forth in Section 2 hereof, the execution, delivery
and effectiveness of this Waiver shall not operate as a waiver of any right,
power or remedy of Lender, nor constitute a waiver of any provision of the Loan
Agreement, or any other documents, instruments or agreements executed and/or
delivered under or in connection therewith.

6. Governing Law. This Waiver shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns and shall be
