Subsequent Events [Abstract] |
Subsequent Events | Note 19. Subsequent Events As of March 2, 2012, a total of 750,000 Series B warrants issued as part of our December 2011 financing were exercised to purchase an aggregate of 750,000 units at a price of $1.25 per unit. Each unit consists of (i) one share of our common stock and (ii) one Series A warrant to purchase one share of common stock. The Series A warrants are immediately exercisable on issuance at an initial exercise price of $1.40 per share and expire on the fifth anniversary of the closing date of the initial financing transaction in December 2011. As a result of these exercises, we issued 750,000 shares of our common stock and 750,000 Series A warrants and received gross proceeds of $938,000. ***** QUARTERLY FINANCIAL DATA (unaudited)
