6.	Line of Credit

We have a revolving line of credit agreement with a financial institution with a current expiration date of November 16, 2012. The credit agreement permits borrowings up to the lesser of $15 million or our borrowing base which is calculated based upon the collateral value of our accounts receivable, inventory, and certain property and equipment. Borrowings under this agreement bear interest at the prime rate, provided, however, that at no time will the rate be less than 4.25% per annum. Borrowings are secured by a pledge of certain of our assets, and the agreement contains various financial covenants, including covenants requiring compliance with certain financial ratios. At March 31, 2012, we had $14.0 million of outstanding borrowings under this agreement and another $0.5 million was reserved for outstanding letters of credit. We believe we are in compliance with all of the financial covenants under this credit agreement.
