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. This Form 4/A is being filed to correct the transaction codes reported in column 4 of Table II of the original Form 4 filed on January 20, 2016 which were inadvertently reported as "J". The correct transaction codes for the covered transactions are reflected in column 4 of Table II of this Form 4/A. ( 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.

Remarks: Except for the change to the transaction codes described in note 1, above, there are no other changes to the original Form 4; however, the number of shares of common stock and the conversion and exercise prices of the derivative securities reported on this Form 4/A have been adjusted to reflect the one-for-nine reverse stock split implemented by the issuer on January 22, 2016.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
