The Second Amendment also amended the definition of “Applicable Margin” increasing the margin determined by reference to the Company’s consolidated net leverage ratio (as defined in the Existing Credit Facility) for purposes of calculating the interest rate for base rate loans, Eurodollar loans and the fee applicable to letters of credit as specified therein.

The foregoing description of the Second Amendment does not purport to be complete and is qualified in its entirety by reference to the Second Amendment, which is filed as Exhibit 10.1 hereto and incorporated herein by reference.
