Item 4. Purpose of Transaction

On July 21, 2017, Strome Mezzanine, HEP and the Issuer entered into the Participation Agreement attached as Exhibit 2 and incorporated by this reference, which was subsequently amended by the Amendment to Participation Agreement, Guaranty, Warrants and Amended and Restated Registration Rights Agreement dated November 15, 2017 attached as Exhibit 3 and incorporated by this reference (the “Amendment,” and the Participation Agreement as so amended, the “Participation Agreement”). The Amendment added Strome Alpha as a party to the Participation Agreement. Under the terms of the Participation Agreement, Strome Mezzanine purchased a participation right for the amount of $1.0 million in the Note, and Strome Alpha purchased a participation right for the amount of $500,000 in the Note. The payments pursuant to the Participation Agreement were paid in three equal tranches; the first two tranches of $500,000 were paid by Strome Mezzanine and the third tranche of $500,000 was paid by Strome Alpha. Upon each payment, Strome Mezzanine or Strome Alpha, as applicable, received the right to convert its payment to 62,500 shares of Common Stock (after giving effect to the Reverse Stock Split), and received immediately exercisable warrants. As of the date of this Amendment, such warrants have expired and are no longer exercisable by the applicable Reporting Person.
