2011 Credit Facility—In July 2011, the Company entered into a Loan and Security Agreement with an institutional lender (the "2011 Credit Facility"), under which the Company borrowed $3.0 million in term loans for general working capital purposes and to refinance the Company's preexisting line of credit. These term loans had an interest rate of 7.25%, and were due in monthly payments of principal and accrued interest over thirty-six months.

On March 30, 2012, the Company entered into a forbearance agreement with the lender, and on April 30, 2012, the Company entered into an amended forbearance agreement to extend the forbearance period and to establish a new loan maturity date of May 7, 2012. On May 7, 2012, the Company repaid in full the 2011 Credit Facility with the proceeds from an approximate $2.3 million term loan made pursuant to the Secured Demand Promissory Note dated as of May 7, 2012. The 2012 Interim Loan bore interest at the rate of 7% per annum. In July 2012, the 2012 Interim Loan was paid in full with the proceeds of the 2012 Term Loan. See Note 5—Note Payable—Related Parties for additional information.

In connection with the repayment of the 2011 Credit Facility, the Company wrote off the remaining balance of the loan acquisition costs and debt discount, resulting in the recognition of a loss on extinguishment of approximately $60,000 in the second quarter of 2012.

Convertible Promissory Notes ("2010/2011 Convertible Debt Offering")—The Company issued convertible promissory notes to new investors during November 2010 totaling $2.1 million and in January 2011 totaling $1.8 million. In addition, holders of other Company debt exchanged their convertible debentures plus accrued interest, totaling $1.8 million for 2010/2011 Convertible Debt Offering notes. The notes bore interest at 8% and converted into common stock on December 30, 2011 at the closing of the Company's IPO. Three holders totaling $0.6 million in principal waived their registration rights under the agreement and, in January 2012, were paid an amount equal to the value of the common stock that would have been issued to them had their principal and accrued interest converted into common stock according to the terms of the agreement.

Promissory Notes—As of June 30, 2012 and December 31, 2011, the Company had $0.5 million and $0.6 million, respectively, outstanding under two promissory notes that do not accrue interest, with maturity dates in 2012 and 2014. At June 30, 2012, $0.3 million of these liabilities were classified as current.
