The securities were sold in units, consisting of one share of common stock and a Warrant to purchase 0.5 of a share of common stock, at a price of $0.50 per unit, for gross proceeds of $3,207,500 (Offering). The Offering closed on February 7, 2012. The Warrants are exercisable at any time on or after August 7, 2012, six months following their issuance. The Warrants are exercisable for cash, or solely in the absence of an effective registration statement, by cashless exercise. After deducting the placement agent fee and our offering expenses (and excluding any potential future proceeds from the exercise of the Warrants) the net proceeds from the Offering were approximately $2.8 million. (See Note 2.) As of September 30, 2012, none of the Warrants had been exercised and all remain outstanding. There are no assurances that any of the Warrants will be exercised or that we will receive any cash proceeds from any such exercise.
