Applicable Margin. For each period commencing on an Adjustment Date through the date immediately preceding the next Adjustment Date (each a “Rate Adjustment Period”), the Applicable Margin for purposes of calculating interest payable with respect to Revolving Credit Loans (in each case, for Base Rate Loans and Eurodollar Rate Loans), for purposes of calculating fees payable in respect of the Letters of Credit and for purposes of calculating the Commitment Fee, as applicable, shall be the applicable percentage set forth below with respect to each such Revolving Credit Loan, Letter of Credit or the Commitment Fee, as the case may be, corresponding to the Adjusted Leverage Ratio, as determined for the most recent Reference Period ending immediately prior to the applicable Rate Adjustment Period:

The Commitment Fee shall be payable quarterly in arrears on the first day of each calendar quarter for the immediately preceding calendar quarter commencing on the first such date following the Closing Date, with a final payment on the Maturity Date or any earlier date on which the Revolving Credit Commitments shall terminate. The commitment fee shall be calculated quarterly in arrears, and if there is any change in the Applicable Margin during any calendar quarter, the Commitment Fee shall be computed separately for each portion of such calendar quarter during which a particular Applicable Margin was in effect using such Applicable Margin.

(d) Section 11.3 of the Credit Agreement is hereby amended by deleting such section in its entirety and substituting in lieu thereof the following new Section 11.3:

For purposes of testing quarterly compliance with this §11.3, the Borrowers shall aggregate Growth Capital Expenditures incurred year-to-date for the then current fiscal year and the Growth Capital Expenditures projected in good faith and based on reasonable assumptions to be made during the balance of such fiscal year after taking into account the Borrowers’ outstanding commitments and projections relating to the opening of new Restaurants.
