Explanation of Responses:

1. The reported transactions involve an amendment of the warrants to amend the expiration date, resulting in the deemed cancellation of the old warrants and the simultaneous issuance of new warrants for purposes of Section 16. The amendment to the warrants was in consideration of the Reporting Person entering into a lockup agreement with the issuer.

2. On January 15, 2016, the registrant amended a preexisting secured note in the aggregate principal amount of $320,000 that was issued to the reporting person on August 7, 2015 so as to make such secured note convertible into shares of common stock of the issuer. As amended, the note has a maturity date of April 15, 2016, provided, however, the reporting person has the right to extend the maturity date for an additional 90 day period.

3. Represents the number of shares of common stock issuable upon conversion of the principal amount of the convertible note at the initial conversion price of the convertible note.
