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 September 23, 2019, the Issuer and the Master Fund entered into a warrant exercise agreement (the “Warrant Exercise Agreement”) pursuant to which the Master Fund exercised all 315,000,000 of its Series B Warrants of the Issuer (collectively, the “Series B Warrants”) in exchange for: (i) 6,700,000 Shares; and (ii) 308,300,000 Series F Prefunded Warrants of the Issuer (collectively, the “Series F Prefunded Warrants”).

The Series F Prefunded Warrants have a perpetual term and are currently exercisable; provided, however, that until the effectuation date of a reverse stock split by the Issuer (the “Reverse Stock Split”), the Issuer is not required to issue upon exercise of the Series F Prefunded Warrants a number of Shares that, when aggregated with any other Shares issued: (i) pursuant to the Warrant Exercise Agreement and the securities purchase agreement entered into the between the Issuer and the Master Fund on June 13, 2019 (the “Securities Purchase Agreement”); (ii) upon prior exercise of the warrants issued pursuant to the Warrant Exercise Agreement or 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 or the Warrant Exercise Agreement, would exceed 231,430,682, 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 Warrant Exercise Agreement. After the effectuation of the Reverse Stock Split, the Series F Prefunded Warrants will not be subject to any beneficial ownership limitation and therefore may be exercised, in whole or in part, at any time. The exercise price of each Series F Prefunded Warrant is $0.001 per Share, subject to adjustment pursuant to the terms of the Series F Prefunded Warrants.

Pursuant to the Warrant Exercise Agreement, the Issuer also issued to the Master Fund 315,000,000 Series E Warrants of the Issuer (collectively, the “Series E Warrants”) as consideration for the Master Fund’s agreement to exercise all of its Series B Warrants. The Series E Warrants are currently exercisable; provided, however, that the Series E Warrants are subject to blocker provision that prevents the Master Fund from exercising the Series E Warrants if it would be more than a 9.99% beneficial owner of the Shares following any such exercise. The exercise price of each Series E Warrant is $0.05, subject to adjustment pursuant to the terms of the Series E Warrants. The term of the Series E Warrants is one year following the effectuation of the Reverse Stock Split.

In connection with the Warrant Exercise Agreement, the Issuer and the Master Fund also entered into an amended and restated 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 Warrant Exercise Agreement in order to register: (i) the Shares acquired by the Master Fund pursuant to the Securities Purchase Agreement, as well as the Shares issuable upon exercise of the warrants issued thereunder; and (ii) the Shares acquired by the Master Fund pursuant to the Warrant Exercise Agreement, as well as the Shares issuable upon exercise of the Series F Prefunded Warrants and Series E 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 Warrant Exercise Agreement, or, in the event of a “full review” by the SEC, within 120 days after the date of the Warrant Exercise Agreement.

Pursuant to the Securities Purchase Agreement, the Master Fund has agreed to vote all of its Shares, by written consent or at a meeting, as of the applicable record date in favor of the Reverse Stock Split.

The foregoing was a summary of certain material terms of the: (i) Warrant Exercise Agreement; (ii) Series F Prefunded Warrants; (iii) Series E Warrants; (iv) Registration Rights Agreement; and (v) Securities Purchase Agreement.

As of the date hereof, each of the Reporting Persons may be deemed to be the beneficial owner of 252,630,682 Shares, constituting 92.2% of the Shares, based upon 273,885,915 Shares outstanding as of the date hereof, as adjusted for warrants of the Issuer beneficially owned by the Reporting Persons.
