These warrants have a certain type of cash settlement feature or their exercise prices or the number of shares for which the warrants may be exercised are subject to adjustment for “down-rounds” and the warrants have been accounted for as derivative instruments as described in Note 2, with the exception of 96,988 warrants issued to the underwriter in August 2014, which did not include the cash settlement feature.
