8. COMMON STOCK AND WARRANTS

In March 2015, we received $2.3 million from the exercise of warrants we issued in connection with earlier financing transactions to purchase 1.1 million shares of our common stock.

During the three months ended March 31, 2015, we received gross proceeds of $1.0 million as part of an At-the-Market (ATM) agreement we entered into with Meyers Associates, L.P. in June 2014. We have completed sales under this agreement, having received total proceeds of $4.5 million before issuance costs of approximately $206,000 from the sale of 2.0 million shares of our common stock.

In March 2014, we raised $13.9 million before issuance costs of approximately $1.0 million through an underwritten offering of 7.2 million shares of our common stock and warrants to purchase 2.1 million shares of our common stock.

In February 2014, we issued 3.7 million shares of our common stock under the warrant exchange provisions of our May and September 2013 registered direct offerings. We recognized a loss of $5.0 million on the exchange as the fair market value of the common stock issued was greater than the obligation recorded due to an increase in our stock price since December 31, 2013 to the date the warrants were exchanged.
