In addition, Borrowers have informed Agent they will not (i) achieve minimum EBITDA for the Covenant Computation Dates ending December 31, 2004, March 31, 2005, June 30, 2005 and September 30, 2005 of at least $8,500,000 or less; (ii) maintain the Interest Coverage Ratio for the Covenant Computation Dates ending December 31, 2004, March 31, 2005, June 30, 2005 and September 30, 2005 of not less than 3.75 to 1.00; (iii) maintain the Fixed Charge Coverage Ratio for the Covenant Computation Date ending December 31, 2004, March 31, 2005, June 30, 2005 and September 30, 2005 of not less than 1.15 to 1.00 and (iv) maintain the Leverage Ratio for the Covenant Computation Dates ending December 31, 2004, March 31, 2005, June 30, 2005 and September 30, 2005 of not more than 2.75 to 1.00; and these failures will constitute Events of Default under the Credit Agreement (the “Additional Defaults”).

In consideration of the waivers requested by Borrowers herein, Borrowers agree to pay a waiver fee equal to $                     and upon receipt of such funds, Agent and the Lenders, by their signatures below hereby waive the Designated Defaults and the Additional Defaults.

Agent shall not, by execution of this letter, be deemed to have waived its rights under any circumstances in connection with any Default or Event of Default now or hereafter existing to the extent the same arises out of the cross default provisions set forth in Sections 8.1(e) or (o) of the Credit Agreement.
