         subsection (c) shall read as follows:

                           "(c) On the terms and conditions set forth herein,

                  Obligations, any Canadian L/C shall be recorded in the

                  the Valuation Date for the purpose of determining L/C
                  Obligations. Any draw on a Canadian L/C shall be repaid in
                  Canadian Dollars in an amount equal to the amount of the draw
                  in Canadian Dollars. If at any time there is a drawing under a
                  Canadian L/C and the Company shall not promptly reimburse such
                  drawing as provided in SECTION 3.3, the Company shall be
                  obligated to immediately repay to the Administrative Agent for
                  the benefit of the Lenders an amount in Dollars equal to the
                  Dollar Equivalent Amount of the Canadian Dollars paid by BofA
                  to the beneficiary of such Canadian L/C on the date of such
                  drawing."

                  at the request or with the consent of the Required Lenders)

                  computed on a quarterly basis and on the Termination Date (or
                  such later date on which such Letter of Credit shall expire or
                  be fully drawn)."

                  (f) SECTION 8.6 is hereby amended in its entirety so that as
         amended it shall read as follows:
