CREDIT FACILITY On March 24, 2011, the Company entered into an amendment to its credit facility, effective March 30, 2011, with a U.S. bank which extends its term until March 29, 2012. The credit facility continues to provide for a $1.5 million revolving line of credit ("revolver") with an advance rate of up to 80% of eligible accounts receivable. At June 30, 2011, available borrowings were approximately $1.5 million based on this formula, and no borrowings were outstanding. The revolver will bear interest at Prime +1.75%. The credit facility is collateralized by the Company's assets, except for its intellectual property rights which are subject to a negative pledge arrangement with the bank. The Company is required to maintain financial covenants based on an adjusted quick ratio of at least 1.5 to 1.0, measured at month end, and minimum tangible net worth of $22 million, increased by 60% of the sum of the gross proceeds received by the Company from any sale of its equity or incurrence of subordinated debt and any positive quarterly net income earned, measured at quarter end (both as defined as per the credit facility). As is usual and customary in such lending agreements, the agreements also contain certain nonfinancial requirements, such as required periodic reporting to the bank and various representations and warranties. The lending agreement also restricts our ability to pay dividends without the bank's consent. The Company has been in compliance with all debt covenants since inception of the credit facility. In 2009, the Company borrowed to finance capital equipment under the then existing credit facility which resulted in a term loan of $977 thousand payable over 36 months in equal monthly installments of principal plus accrued interest. The balance outstanding at June 30, 2011 is $299 thousand. Interest expense related to the term loan was $11 thousand and $21 thousand for the six months ended June 30, 2011 and 2010, respectively.
