The fair value of the Company's common stock was derived implicitly from the Private Placement during April through June 2011 at $1.25 per Unit, wherein one Unit was comprised of one share of common stock and one warrant to purchase one share of common stock at an exercise price of $1.60 per share.

(C)

The fair value of the Company's common stock was derived implicitly from the public offering filed in February 2012 at $6.00 per share.
