respect to the fiscal quarter ended March 31, 2005 due to Borrowers' failure to
maintain its required Net Worth at the end of such fiscal quarter and (ii)
Section 12(p) and Section 12(r) of the Credit Agreement with respect to the
fiscal quarter ending March 31, 2005 due to Borrowers' failure to maintain the
requisite Fixed Charge Coverage Ratio and EBITDA level for the four fiscal
quarters then ended. Borrowers have requested that such Events of Default be
waived. By its signature below, Lender hereby waives such Event of Default
solely for the fiscal quarter ending March 31, 2005.
