Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	The reported transactions relate to an amendment of the exercise price of an outstanding warrant from $0.75 per share to $0.35 per share of Common Stock, contingent upon the Reporting Person immediately exercising the Warrant. As a result of this amendment, the outstanding warrant was deemed canceled and a replacement warrant was issued for the same number of shares of Common Stock, but with the reduced exercise price. The outstanding warrant was originally issued on August 2014.
