These warrants have a certain type of cash settlement feature or their exercise prices or the number of shares for which the warrant may be exercised are subject to adjustment for “down-rounds” and the warrants have been accounted for as derivative instruments as described in Note 3, with the exception of 9,699 warrants issued in August 2014.
 
(2)
Due to the issuance of common stock at $22.00 per share as part of the October 2015 Registered Offering, the remaining outstanding warrants issued as part of the February 2013 Public Offering were adjusted to reflect the revised exercise price of $22.00 each.
