[1] The common stock shares and additional paid-in capital for all periods presented reflect the one-for-twelve reverse stock split which took effect on January 27, 2014.
[2] This Warrant was issued in connection with the issuance of warrants to purchase shares of our Series A Preferred Stock to the Third Security Investors in December 2010. The number of underlying shares shown reflects the number of shares of common stock issuable upon conversion of the shares of Series A Preferred Stock for which this Warrant is currently exercisable.
[3] These Warrants were issued in connection with the Private Placement completed in February 2012 and are classified as a liability in our financial statements. See Footnote 12 - Fair Value. These warrants also contain certain anti-dilution provisions that provide for an adjustment to the exercise price and number of shares issuable upon exercise of the warrant in the event that we engage in certain issuances of shares of our common stock at a price lower than the exercise price of the warrant.
