9.	LINE OF CREDIT

On July 11, 2006, the Company entered into a loan agreement providing for an available line of credit of $30.0 million, which was most recently amended on June 18, 2009. Loans under the Amended and Restated Loan Agreement, as amended, bear interest at the rate of LIBOR plus a fixed percentage between 2.25% and 2.50% and require the Company to maintain a minimum cash balance and tangible net worth measured at the end of each of the Company's fiscal quarters. As of December 31, 2011, the Company was in compliance with all of the covenants under the Amended and Restated Loan Agreement, as amended. The term of the Amended and Restated Loan Agreement, as amended, extends to March 31, 2012. The Company has not drawn on this line of credit. The Company believes it will be able to renew its line of credit upon the expiration of the current Amended Loan Agreement, although the terms and conditions may change.
