These warrants have a certain type of cash settlement feature or the exercise price for which the warrant may be exercised is 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 9,704 warrants issued in August 2014.
 
(2)
Due to the issuance of common stock at $1.50 per share as part of the November 2016 Underwritten Offering, the remaining outstanding warrants issued as part of the February 2013 Public Offering were adjusted to reflect the revised exercise price of $1.50 each.
