(“Citizens”) pursuant to a Credit and Security Agreement by and among the Company, certain affiliates thereof as borrowers or guarantors, and Citizens (the “Credit Agreement”).

The Credit Agreement contains customary affirmative and negative covenants, including, among others, financial covenants based on the Company’s leverage and fixed charge coverage ratios, as well as an obligation to maintain a minimum availability requirement of at least $5.0 million in the aggregate of cash and availability under the line of credit. The Credit Facility will provide funds for general corporate purposes and repurchases of issued and outstanding capital stock of the Company.
