For purposes of determining the Applicable Margin and the Applicable Letter of Credit Fee Rate:

(b)    The Applicable Margin, the Applicable Commitment Fee Rate and the Applicable Letter of Credit Fee Rate shall be recomputed as of the end of each fiscal quarter ending after the Closing Date based on the Net Debt/EBITDA Ratio as of such quarter end.

The Borrower's obligations under this paragraph shall survive the termination of the Commitments and the repayment of all other Obligations hereunder.
