In December 2008, the Company entered into a credit facility with a financial institution. The amount of borrowings available under the credit facility was based on the Company's monthly accounts receivable balance and amounts borrowed were collateralized by the Company's personal property. As of January 31, 2011 the interest rate was 4.5%. In February 2011, the credit facility was extended to June 2011. As of January 31, 2011, the Company's outstanding balance under the credit facility was $6.0 million. The collateral for the amended credit facility consisted of all Company personal and intellectual property other than property securing the equipment financing line described below. On May 13, 2011, the credit facility was paid in full and terminated.

In September 2009, the Company entered into a $2.0 million equipment financing line with a financial institution. Each draw on the equipment financing line bore interest at the rate of 9.0% per annum and matured in 36 months. For the first six months after each advance, the Company was required to pay interest only, after which the Company was required to make 30 equal monthly payments of interest and principal. As of January 31, 2011 the Company had drawn $1.6 million on the equipment financing line, with the latest draw maturing in September 2013. The collateral for the equipment financing line consisted of all equipment purchased under the agreement by the Company. On May 13, 2011, the equipment financing line was paid in full and terminated.

On May 13, 2011, the Company entered into a $30 million credit facility with a syndicate of financial institutions. The amount of borrowings available under the credit facility at any time is based on the Company's monthly accounts receivable balance at such time, and the amounts borrowed are collateralized by the Company's personal property (including such accounts receivable but excluding intellectual property). At the option of the Company, drawn amounts under the credit facility will bear an interest rate of either (i) an adjusted London Interbank offered, or LIBO, rate plus (A) 3.00% (if the debt outstanding is greater than or equal to $15 million) or (B) 2.75% (if the debt outstanding is less than $15 million) or (ii) an alternate base rate plus (x) 2.00% (if the debt outstanding is greater than or equal to $15 million) or (y) 1.75% (if the debt outstanding is less than $15 million). The adjusted LIBO rate is the LIBO rate for a particular interest period multiplied by the statutory reserve rate. The alternate base rate is the greatest of the prime rate, the federal funds effect rate plus 0.5% and the adjusted LIBO rate plus 1%. In addition, the Company pays a non-usage charge on the available balance. The non-usage charge is 0.5% if the debt outstanding is greater than or equal to $15 million and .625% if the debt outstanding is less than $15 million. As of October 31, 2011, the Company had drawn $0 and had $30 million of available borrowing capacity under the credit facility. The credit facility contains customary events of default, conditions to borrowing and covenants, including restrictions on the Company's ability to dispose of assets, make acquisitions, incur debt, incur liens and make distribution to stockholders. The credit facility also includes a financial covenant requiring the maintenance of minimum liquidity of at least $5 million. During the continuance of an event of a default, the lenders may accelerate amounts outstanding, terminate the credit facility and foreclose on all collateral.
