Secured credit facility description       The Company is required to maintain minimum adjusted EBITDA levels (calculated on a twelve-month rolling basis as defined in the agreement) if the Company’s availability under its senior secured revolving credit facility is below $8.0 million for any five consecutive business days. Failure to meet the minimum adjusted EBITDA covenant in the event that availability falls below $8.0 million as described above is considered an event of default, that could result in the outstanding balances borrowed under the Company’s senior secured term loan and senior secured revolving credit facility becoming due immediately, and will result in cross defaults on the Company’s other borrowings.
