Note 2. Revolving Credit Agreement

The Company entered into a secured revolving credit agreement with The Private Bank and Trust Company dated as of March 5, 2009 (the “Credit Agreement”) and subsequently entered into amendments to its Credit Agreement to extend the maturity date to March 31, 2013 and amend certain other provisions. The Credit Agreement is an asset-based revolving credit facility in an amount up to $12.0 million based on 80% of eligible accounts receivable plus the lesser of 30% of eligible inventory or $3.0 million. The obligations of the Company under the Credit Agreement are secured by a guaranty from certain subsidiaries of the Company, and by substantially all of the assets of the Company.

The revolving loans under the Credit Agreement bear interest at the greater of the London Interbank Offered Rate (“LIBOR”) plus a spread of 2.25%, or an alternative base rate. The alternative base rate is the greater of prime rate or the Federal Funds rate (the “Base Rate”) less 0.25%. The Company is also required to pay a non-use fee of 0.2% per annum on the unused portion of the revolving loans. The fee is waived if the Company maintains with the lender an average monthly non-interest bearing account balance of $5.0 million and an average monthly balance of $15.0 million consisting of other investments. The Company has maintained such balances since entering the Credit Agreement.

The Credit Agreement contains financial covenants that include a minimum tangible net worth and a limitation on capital expenditures for any fiscal year. The Company was in compliance with these covenants on September 30, 2012. As of September 30, 2012, the Company had no debt and approximately $7.2 million available under the Credit Agreement.

In addition, although the Company has never declared or paid any cash dividends on its common stock and does not anticipate paying any cash dividends in the foreseeable future, the Company’s credit facility restricts the Company’s ability to pay dividends without bank approval.
