January 2017,
Dr. Michael Goldberg, the Company’s President and CEO, exercised
5,411,850
of his Series LL warrants in exchange for
5,411,850
shares of our common stock, resulting in proceeds to the Company of

In
March 2017,
in connection with the Asset Sale, the Company granted to each of Cardinal Health
414

five
-year Series NN warrant to purchase up to
10
million shares and
1
million shares, respectively, of the Company’s common stock at an exercise price of
$1.50
per share, each of which warrant is subject to anti-dilution and other customary terms and conditions. The fair value of the Series NN warrants was calculated using the Black-Scholes model using our
