During the six months ended June 30, 2013, the Series E warrants, along with related warrants with similar terms, were exchanged for 1,023,264 shares of common stock and these warrants were extinguished, thereby removing the “overhang” created by the full-ratchet provisions of these warrants that would have increased the number of warrants outstanding and reduced the exercise price of these warrants to the price of any subsequent financing done at a lower price. This exchange of common stock for the Series E warrants resulted in a fair value charge of $3,069,792 during the six months ended June 30, 2013. These 1,023,264 shares of common stock were valued at $3.00 per share, which was the price at which the Company sold 139,167 shares during the three months ended June 30, 2013, resulting in the fair value charge of $3,069,792.
