During the nine-month periods ended September 30, 2013 and 2012, we paid interest aggregating $1.2 million and $476,000, respectively. During the nine-month periods ended September 30, 2013 and 2012, we issued 22,126 and 17,390 shares of our common stock, respectively, as matching contributions to our 401(k) plan.

In conjunction with the GECC/MidCap Loan Agreement and the Crede Securities Purchase Agreement, we issued warrants with estimated fair values of $631,000 and $7.7 million, respectively. Additionally, $1.0 million of the debt discount fees related to the GECC/MidCap Loan Agreement have been deferred through the maturity date of the loan.
