CUSIP NO. 67107W100

Item 3.

Source and Amount of Funds or Other Consideration.

The Shares purchased by Lone Star Value Investors were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market purchases, except as otherwise noted, as set forth in Schedule A, which is incorporated by reference herein. The aggregate purchase price of the 77,585,000 Shares beneficially owned by Lone Star Value Investors is approximately $4,025,322, excluding brokerage commissions.

Item 4.

Purpose of Transaction.

The Reporting Persons purchased the Shares based on the belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to Lone Star Value, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, Lone Star Value may endeavor to increase or decrease its position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as Lone Star Value may deem advisable.

Lone Star Value believes the Issuer’s Shares are meaningfully undervalued versus the Issuer’s peers and its net asset value per Share. Lone Star Value notes that the Issuer’s stock price has significantly underperformed its peers and the NASDAQ Composite Index over the short-, medium- and long-term and has recently reached levels past seen only during the 2008 financial crisis. In addition, the Issuer’s stock price remains below the price of every equity issuance by the Issuer over the last fifteen years.

Lone Star Value sees significant value in the Issuer’s patent portfolio and believes that its current trading levels – in which a negative enterprise value is being ascribed based on the current share price – reflect a lack of confidence in the current management and Board’s direction for the Company. Lone Star Value believes the Issuer can be a profitable enterprise and wishes to engage with management and the Board in raising the value of Issuer’s shares through discussions on improving the Issuer’s operational focus as well as realizing the value of its intellectual property and long term investments, all of which Lone Star Value believes can meaningfully enhance shareholder value.

In Lone Star Value’s view, the Issuer could unlock shareholder value by streamlining its operations, using its cash to repurchase shares or issuing a dividend, potentially liquidating certain or all of its equity stakes currently listed as long term investments, and licensing its intellectual property.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. Lone Star Value intends to review its investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, Lone Star Value may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, continuing to engage in communications with management and the Board of the Issuer, engaging in discussions with stockholders of the Issuer and others about the Issuer and Lone Star Value’s investment, making proposals to the Issuer concerning strategic alternatives available to the Issuer, changes to the capitalization, ownership structure, board structure (including board composition) or operations of the Issuer, purchasing additional Shares, selling some or all of their Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, or changing their intention with respect to any and all matters referred to in Item 4.
