Debt	Note 5. Debt The Company entered into its Second Amended and Restated Business Loan and Security Agreement ("Credit Facility") on February 20, 2008, with a syndication of nine commercial banks to allow for borrowings of up to $350.0 million for a period of five years (maturing February 20, 2013) under a revolving line of credit. The Credit Facility provides for borrowings of up to $275.0 million without a borrowing base requirement and also provides for an "accordion feature," which permits additional revolving credit commitments of up to $75.0 million, subject to lenders' approval. The Credit Facility provides for pre-approval by the lenders for acquisitions with individual purchase prices of up to $75.0 million, if certain conditions are met. The Credit Facility is collateralized by substantially all of the assets of the Company, and requires that the Company remain in compliance with certain financial and non-financial covenants. The financial covenants, as defined by the Credit Facility, require that the Company maintain, on a consolidated basis for each quarter, a fixed charge coverage ratio of not less than 1.25 to 1.00 and a leverage ratio of not more than 3.50 to 1.00.

The Company has the ability to borrow funds under its Credit Facility at interest rates based on both LIBOR and prime rates, at its discretion, plus their applicable margins.
