2.                                      Waiver.  Effective as of the date hereof, the Administrative Agent and the Required Lenders party hereto hereby agree to waive any Events of Default occurring as a result of the Borrower’s failure to comply with (i) the minimum Interest Coverage Ratio required by

In reliance on the representations and warranties set forth in Section 4 below and subject to the satisfaction of the conditions set forth in Section 5 below, the parties hereby agree to the following amendments.

5

Equity Contribution); provided that neither the Administrative Agent nor the Lenders shall exercise any rights or remedies (other than instituting Default Interest) with respect to any Event of Default that exists pursuant to Section 6.2 during the ten (10) Business Day period following notice by the Borrower that it intends to make such Specified Equity Contribution and affect such recalculation.  If, after giving effect to such recalculation, the Loan Parties are in compliance with the financial covenants, the Loan Parties shall be deemed to have satisfied the requirements of the financial covenants as of the relevant date of determination with the same effect as though there had been no failure to comply therewith at such date.”
