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) This Warrant was previously reported as relating to 30,000 shares with an exercise price of $3.00 per share. As a result of the Warrant's adjustment provisions, the Warrant was adjusted to relate to 96,774 shares and an exercise price of $0.93 per share. This Warrant has been exercised in exchange for a cash payment by the reporting owner. This Warrant was acquired in 2011 in connection with the purchase of Issuer Common Stock, and it is being exercised prior to its expiration date of May 31, 2016. The Reporting Person intends to hold the shares of common stock.
(2) Warrant became exercisable upon issuance.
(3) As previously reported on February 12, 2015, the Reporting Person held a total of 96,774 exercisable Warrant shares. The total beneficially owned derivative securities reported at the time inadvertently included securities of a separate class, and, accordingly, such previously reported shares are now properly excluded.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
