The Swing Line Lender shall have the right in its sole discretion to suspend or terminate the making and/or prepayment of Swing Loans pursuant to such Sweep to Loan Arrangement with notice to the Sweep Depositary and the Borrower Representative (which may be provided on a same-day basis), whether or not any Default or Event of Default exists. The Swing Line Lender shall not be liable to the Borrowers or any other Person for any losses directly or indirectly resulting from events beyond the Swing Line Lender’s reasonable control, including without limitation any interruption of communications or data processing services or legal restriction or for any special, indirect, consequential or punitive damages in connection with any Sweep to Loan Arrangement.”

(b) Section 1.18 (Incremental Commitment Increases). Section 1.18(a) of the Credit Agreement is hereby amended and restated in its entirety as follows:

“Section 1.18. Incremental Commitment Increases.

The Applicable Margin shall be established based on the Total Funded Debt/EBITDA Ratio for the most recently completed fiscal quarter and the Applicable Margin established on a Pricing Date shall remain in effect until the next Pricing Date.

(e) if a new Subsidiary is formed or acquired as a result of or in connection with the Acquisition, the Borrowers shall have complied with the requirements of Section 4 hereof in connection therewith to the extent required by such Section;

(j) after giving effect to the Acquisition and any Credit Event in connection therewith, there shall not be less than $25,000,000 of Excess Availability; and

(k) Borrower Representative shall certify the satisfaction of the foregoing conditions on or prior to the date such Acquisition is consummated.

“Revolving Credit Commitment” means, as to any Lender, the obligation of such Lender to make Revolving Loans and to participate in Swing Loans and Letters of Credit issued for the account of the Borrowers hereunder in an aggregate principal or face amount at any one time outstanding not to exceed the amount set forth opposite such Lender’s name on Schedule 1 attached hereto and made a part hereof, as the same may be reduced or modified at any time or from time to time pursuant to the terms hereof.
