NOW THEREFORE, in consideration of the mutual covenants, provisions and covenants contained herein, the parties agree as follows:

1.                                       Terms used herein and not otherwise defined shall have the meaning as those ascribed thereto in the Credit Agreement.

2.                                       Section 6.02 is amended by the addition of subsection 6.02(i) as follows:

“(i) in the event the Parent Guarantor notifies the Administrative Agent, in accordance with section 7.11(c) that the calculation in section 7.11(c)(B) shall apply to a fiscal quarter, a Certificate of Minimum Liquidity Amount for each month in the applicable fiscal quarter, to be delivered within 10  Business Days of each month end in such fiscal quarter.”

3.                                       Section 7.11(c) is deleted and replaced with the following:

“(c)  Consolidated Interest Coverage Ratio and Minimum Liquidity Amount.

(A) Permit the Consolidated Interest Coverage Ratio as at the end of any fiscal quarter of the Parent Guarantor to be less than 4.00 to 1.00; or, (B) fail to maintain the Minimum Liquidity Amount calculated as at the end of each month.

At least ten Business Days prior to the commencement of each fiscal quarter, the Parent Guarantor shall notify the Administrative Agent whether the calculation in section 7.11(c)(A) or section 7.11(c)(B) shall apply to such quarter.  In the event the Parent Guarantor indicates that section 7.11(c)(B) shall apply to such quarter, the Parent Guarantor shall provide the Administrative Agent with a Certificate of Minimum Liquidity Amount within 10 Business Days of each month end in such quarter.  In the event the Parent Guarantor fails to notify the Administrative Agent of which calculation in section 7.11(c) is to apply to a fiscal quarter, the calculation in section 7.11(c)(B) will be deemed to apply.”
