Item 4.

Ownership:

(a)

Amount Beneficially Owned: 4,020,058* shares of Common Stock as of December 10, 2015

(b)

Percent of Class: 9.99%*

The Reporting Persons’ beneficial ownership of 4,020,058* shares of Common Stock constitutes 9.99%* of all the outstanding shares of Common Stock, based upon 36,220,761 shares of Common Stock outstanding as of November 13, 2015, as reported by the Issuer in its most recent Form 10-Q, plus shares of Common Stock issuable upon conversion of the Note (as defined below) and the issuance and delivery of 2,563,724 shares of Common Stock due following the exercise of the Warrant (as defined below).

(c)

Number of shares as to which such person has:

(i)

sole power to vote or to direct the vote: 0

(ii)

shared power to vote or to direct the vote: 4,020,058*

(iii)

sole power to dispose or to direct the disposition of: 0

(iv)

*Subject to the Ownership Limitation (defined below), the Reporting Persons may be deemed to beneficially own a total of 4,831,765 shares of Common Stock, consisting of (i) 2,268,041 shares of Common Stock issuable upon conversion of a 10% OID Convertible Note Due January 1, 2016 (“Note”) issued to Gemini Master Fund, Ltd. (“Gemini”) in the principal amount of $220,000 (which Note has accrued interest thereon of $22,000 and a current conversion price of $0.1067), and (ii) 2,563,724 shares of Common Stock currently issuable to Gemini following its exercise in full, on a cashless exercise basis (“Warrant Exercise”), of a Warrant issued to Gemini in connection with the Note (the “Warrant”).

In accordance with Rule 13d-4 under the Securities Exchange Act of 1934, as amended, because the number of shares of Common Stock into which the Note is convertible is limited, pursuant to the terms of such instrument, to that number of shares of Common Stock which would result in the Reporting Persons having beneficial ownership of 9.99% of the total issued and outstanding shares of Common Stock (the "Ownership Limitation"), the Reporting Persons disclaim beneficial ownership of any and all shares of Common Stock that would cause any Reporting Person's beneficial ownership to exceed the Ownership Limitation. Therefore, in accordance with the Ownership Limitation, based upon 36,220,761 shares of Common Stock outstanding, each of the Reporting Persons beneficially owns 4,020,058 shares of Common Stock and disclaims beneficial ownership of 811,708 shares of Common Stock issuable conversion of the Note.

Gemini delivered notice of the Warrant Exercise on or about November 25, 2015 in accordance with the terms of the Warrant, exercising the Warrant on a cashless basis for a net deliverable amount of shares of Common Stock equal to 2,563,724 shares (“Shares”). Under the terms of the Warrant the Issuer was required to issue and deliver the Shares to Gemini within three trading days, but the Issuer has failed to deliver the Shares to date. The Issuer has disputed the number of Shares issuable upon exercise of the Warrant and has refused to issue any Shares. Gemini has commenced an enforcement action against the Issuer in the United States District Court for the Southern District of New York to compel the Issuer to honor its obligations under the Warrant. The Reporting Persons will update this Schedule 13G following any resolution from the Court which affects the disclosures contained herein.

In addition, as permitted by Rule 13d-4, the filing of this statement shall not be construed as an admission that Gemini Strategies LLC, Inc., in its capacity as investment manager for Gemini, is the beneficial owner of the Shares, the Note or Warrant, or that Steven Winters, in his capacity as president or principal of Gemini Strategies LLC, Inc., is the beneficial owner of the Shares, the Note or Warrant. Each of Gemini Strategies LLC, Inc. and Steven Winters expressly disclaims any equitable or beneficial ownership of the Shares, the Note and Warrant.

Item 5.
