Armistice Capital is an investment adviser registered with the Securities and Exchange Commission (the “SEC”) that is principally engaged in the business of providing investment management services to private investment vehicles, including the Master Fund. The principal business address of Armistice Capital is 510 Madison Avenue, 7^th Floor, New York, New York 10022.

The Master Fund is principally engaged in the business of investing in securities. The principal business address of the Master Fund is c/o dms Corporate Services Ltd., 20 Genesis Close, P.O. Box 314, Grand Cayman KY1-1104, Cayman Islands. The board of directors of the Master Fund consists of Steven Boyd, Kevin A. Phillip and Gregory S. Bennett.

Steven Boyd is the managing member of Armistice Capital and a director of the Master Fund. Mr. Boyd’s business address is 510 Madison Avenue, 7^th Floor, New York, New York 10022.

On June 13, 2019, the Issuer and the Master Fund entered into a securities purchase agreement (the “Securities Purchase Agreement”) pursuant to which the Master Fund acquired from the Issuer in a private placement (the “Private Placement”): (i) 13,000,000 Shares; (ii) 315,000,000 Series A Warrants of the Issuer (the “Series A Warrants”); (iii) 315,000,000 Series B Warrants of the Issuer (the “Series B Warrants”); and (iv) 302,000,000 Series C Prefunded Warrants of the Issuer (the “Series C Prefunded Warrants”, and collectively with the Series A Warrants and Series B Warrants, the “Warrants”). The Master Fund also agreed to vote all of its Shares, by written consent or at a meeting, as of the applicable record date in favor of the Issuer’s plan to effectuate a reverse stock split (the “Reverse Stock Split”).

The Warrants are currently exercisable; provided, however, that until the effectuation date of the Reverse Stock Split, the Issuer is not required to issue upon exercise of the Warrants a number of Shares that, when aggregated with any other Shares issued: (i) pursuant to the Securities Purchase Agreement; (ii) upon prior exercise of the Warrants issued pursuant to the Securities Purchase Agreement; and (iii) pursuant to any warrants issued to any registered broker-dealer as a fee in connection with the issuance of Shares pursuant to the Securities Purchase Agreement, would exceed 247,161,824, subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Shares that occur after the date of the Securities Purchase Agreement.

The exercise prices for the Warrants are as follows: (i) $0.022 per share in respect of each Series A Warrant; (ii) $0.02 in respect of each Series B Warrant; and (iii) $0.001 in respect of each Series C Prefunded Warrants, in each case, subject to adjustment pursuant to the terms of the relevant Warrant. The terms of the Warrants are as follows: (i) the Series A Warrants have a term of five years following the effectuation of the Reverse Stock Split; (ii) the Series B Warrants have a term of one year following the effectuation of the Reverse Stock Split; and (iii) the Series C Prefunded Warrants have a perpetual term. None of the Warrants are subject to beneficial ownership blocker provisions; therefore, the Warrants may be exercised, in whole or in part, at any time after effectuation of the Reverse Stock Split.

In connection with the Private Placement, the Issuer and the Master Fund also entered into a registration rights agreement (the “Registration Rights Agreement”), pursuant to which the Issuer agreed to file a registration statement (“Registration Statement”) with the SEC within 60 days after the date of the Private Placement in order to register the Shares acquired by the Master Fund pursuant to the Securities Purchase Agreement, as well as the Shares issuable upon exercise of the Warrants. The Issuer also agreed to use its best efforts to cause the Registration Statement to be declared effective within 90 days after the date of the Private Placement, or, in the event of a “full review” by the SEC, within 120 days after the date of the Private Placement.

The foregoing was a summary of certain material terms of the: (i) Securities Purchase Agreement; (ii) Series A Warrant; (iii) Series B Warrant; (iv) Series C Prefunded Warrant; and (v) Form of Registration Rights Agreement. The foregoing descriptions are not, and do not purport to be, complete and, except as otherwise described above, are qualified in their entirety by reference to the full text of the forms of those documents, which have been filed as Exhibits B, C, D, E and F, respectively, and are incorporated herein by reference.

As of the date hereof, each of the Reporting Persons may be deemed to be the beneficial owner of 244,561,824 Shares, constituting 94.9% of the Shares, based upon 257,617,057 Shares outstanding as of the date hereof, as adjusted for the Warrants beneficially owned by the Reporting Persons.
