F6The Reporting Persons are jointly filing this Form 4 pursuant to Rule 16(a)-3(j) under the Exchange Act. The Form 4 for certain additional Reporting Persons is being filed separately and simultaneously with this Form 4 due to the limitation of ten Reporting Persons per filing.
F7On March 8, 2018, the Reporting Person received the Series D Warrants to purchase shares of Common Stock in connection with a mandatory conversion of the Series B Preferred Stock. As a result of the mandatory conversion, the Issuer converted all of Reporting Person's outstanding shares of the Series B Preferred Stock into Series D Warrants.
F8Each Series D Warrant is immediately exercisable at the option of the holder for one share of Common Stock at a price equal to $0.0001. The Series D Warrants are also exercisable at the option of the Issuer in connection with a full redemption of the Series A Preferred Stock or upon a change of control of the Issuer. At all times a holder of Series D Warrants, who is not a beneficial owner of 10% or more of the outstanding Common Stock, may exercise only up to that number of Series D Warrants so that, upon exercise, the aggregate beneficial ownership of Common Stock of such holder and all persons affiliated with such holder, is not more than 9.99% of Common Stock then outstanding (other than in connection with a change of control of the Issuer). As of the filing date, Reporting Persons may be deemed to beneficially own more than 10% of the outstanding Common Stock.
