Warrants issued in connection with the bridge notes, exercise terms       The Warrants are exercisable for five years after the closing date of the Purchase Agreement. For each $1,000 of principal amount of Bridge Notes, the holder received 1,200 Warrants to purchase the Company’s common stock. Each holder is entitled to exercise one-third of all warrants received at an exercise price of $3.00, one-third of all warrants received at an exercise price of $3.50, and one-third of all warrants received at an exercise price that is equal to the closing price on the closing date of the Purchase Agreement, $2.94. Pursuant to the terms of the Purchase Agreement, the Company has agreed to register the shares underlying the Bridge Notes and the Warrants.          
Bridge notes, conversion terms The Company closed the sale of its Series A Preferred Stock which resulted in the reduction of the conversion price of the Bridge Notes held by the institutional investors to $2.00 from $2.50 to equal the conversion price of the Series A Preferred Stock. In addition, two additional 90 extensions were provided to the institutional investors, which could extend the final maturity date to July 15, 2015. In the event the bridge notes are converted to equity, the incremental fair value of modified bridge notes will be recognized in the consolidated statement of operations.
