The Senior Secured Credit Facility includes various customary restrictive covenants, including restrictions related to the ratio of secured debt to earnings before interest expense, taxes, depreciation and amortization (secured leverage ratio) and the ratio of earnings before interest expense, taxes, depreciation and amortization to interest expense (coverage ratio).
