Credit Facility	5. Credit Facility In October 2008, we entered into a $19.5 million credit facility with California Bank & Trust (“CB&T”). This credit facility provided for a two-year revolving line of credit with borrowings of up to $12.0 million and a $7.5 million 48-month term note. In September 2010, we entered into a modification agreement with CB&T to extend the expiration date of our revolving line of credit to October 1, 2012. We repaid in full all principal and interest payments under the term note in June 2012; the term note contained no early termination fees. In September 2012, we entered into a second modification agreement with CB&T to extend the expiration date of our revolving line of credit to October 1, 2014. Interest on borrowed amounts under the revolving line of credit is payable monthly at a rate equal to the current stated prime rate (3.25% at June 30, 2013) up to the current stated prime rate plus 0.25%, depending on aggregate deposit balances maintained at the bank in relation to the total loan commitment under the credit facility. We are obligated to pay an unused line fee of 0.25% per annum applied to the average unused portion of the revolving line of credit during the preceding month. The revolving line of credit does not contain early termination fees and is secured by substantially all of our assets. As of June 30, 2013 and June 30, 2012, no amounts were outstanding under the revolving line of credit portion of the credit facility. Availability under this line of credit may be reduced or otherwise limited as a result of our obligations to comply with certain financial covenants.
