The following constitutes Amendment No. 10 to the Schedule 13D filed by the undersigned (the “Amendment No. 10”). This Amendment No. 10 amends the Schedule 13D as specifically set forth herein.

Item 4 is hereby amended to add the following:

On September 5, 2017, the Issuer entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) with RhythmOne plc, a public limited company incorporated under the laws of England and Wales (“RhythmOne”), Redwood Merger Sub I, Inc., a Delaware corporation and a wholly owned subsidiary of RhythmOne, and Redwood Merger Sub II, Inc., a Delaware corporation and a wholly owned subsidiary of RhythmOne.

On February 2, 2018, pursuant to the terms and conditions of the Merger Agreement, RhythmOne completed its acquisition of the Issuer. As a result of the acquisition, the Shares were converted, at the effective time, into the right to receive (i) $1.70 in cash and (ii) 0.7325 ordinary shares of RhythmOne, plus cash in lieu of any fractional shares in each case, without interest and less any applicable withholding taxes (the “Transaction Consideration”). Accordingly, at the effective time, the Reporting Persons ceased to have any rights as stockholders of the Issuer, other than the right to receive the Transaction Consideration.

In accordance with the Merger Agreement, as of the effective time, Mr. Singer ceased to serve as a member of the Board and, in connection therewith, Mr. Singer also ceased serving on any committees of which he was a member.

Item 5 is hereby amended and restated to read as follows:

(a)-(b) Effective February 2, 2018, as a result of the acquisition described in Item 4, each Share owned by the Reporting Persons was converted into the right to receive the Transaction Consideration. Accordingly, the Reporting Persons no longer beneficially own any securities of the Issuer.

(c) The Reporting Persons have not entered into any transactions in the Shares during the past sixty (60) days.

(d) Not applicable.

(e) As of the close of business on February 2, 2018, the Reporting Persons ceased to be the beneficial owners of more than 5% of the Shares of the Issuer.
