| Interest rate terms | (Under the terms of the Facility, the Company has multiple borrowing options, including borrowing at a rate tied to adjusted LIBOR plus a spread of 225 to 300 basis points, which is adjusted based on a leverage ratio. The borrowing spread was 250 basis points as of July 2, 2011. The Company may also borrow at the highest of the following, plus a spread of 125 to 200 basis points, which is adjusted based on a leverage ratio 150 basis points as of July 2, 2011: the Federal Funds rate plus 0.50 percent, the Prime Rate established by JPMorgan Chase Bank, N.A. or the one month adjusted LIBOR rate plus 1.00 percent.

| Covenant requirements | (The Company's borrowing capacity may also be affected by the fixed charge covenant included in the Facility. The covenant requires that the Company maintain a fixed charge coverage ratio, as defined in the agreement, of greater than 1.0 times, whenever unused borrowing capacity, plus certain cash balances together representing Availability falls below 37.5 million. At the end of the second quarter of 2011, the Company had a fixed charge coverage ratio in excess of 1.0 times, and therefore had full access to borrowing capacity available under the facility. When the fixed charge covenant ratio is below 1.0 times, the Company is required to maintain at least 37.5 million of Availability in order to be in compliance with the covenant. Consequently, the borrowing capacity is effectively reduced by 37.5 million whenever the fixed charge covenant ratio falls below 1.0 times.) | |||||||||||||||||||||||||||||||||
