Item 3.     Source and Amount of Funds or Other Consideration

On July 11, 2013, Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”) with GO Merger Sub LLC, a wholly-owned subsidiary of Issuer (“Merger Sub”), Walker Digital and Walker Digital Holdings, LLC, a wholly-owned subsidiary of Walker Digital (“Walker Digital Sub”), pursuant to which, on September 18, 2013 (the “Closing Date”), Merger Sub merged with and into Walker Digital Sub (the “Merger”), with Walker Digital Sub surviving the Merger and becoming a wholly-owned subsidiary of Issuer. At the effective time of the Merger, all of the issued and outstanding membership interests in Walker Digital Sub were converted into 14,999,000 shares of Issuer’s newly-designated Series B Convertible Preferred Stock, par value $0.001 per share (the “Series B Preferred Stock”), and 7,667,667 shares of Common Stock (collectively, the “Merger Consideration”). As a result of the Merger, Walker Digital acquired 37.1% of Issuer’s issued and outstanding Common Stock and 100% of Issuer’s issued and outstanding Series B Preferred Stock (and, assuming conversion of all such shares of Series B Preferred Stock, 63.5%, of Issuer’s issued and outstanding Common Stock).

Item 4.     Purpose of Transaction

Walker Digital entered into the Merger for the purpose of acquiring a controlling interest in Issuer. In connection with the Merger and pursuant to the terms of a Lock-Up Agreement dated as of July 11, 2013 between Issuer and Walker Digital, as amended, Walker Digital agreed that for a period of 12 months following the closing of the Merger, it will not sell or transfer any of the shares of Common Stock or Series B Preferred Stock received in the Merger to any person, other than (i) to affiliates and to current and former officers or members of Walker Digital and its affiliates (and on the condition such transferees enter into a similar lock-up agreement), (ii) upon a pledge of such securities (and on the condition such pledgee will enter into a similar lock-up agreement) or (iii) a transfer of shares of Common Stock in a secondary offering as part of a registered public offering that includes primary shares or in a privately negotiated sale of unregistered securities to third parties (not affiliated with Walker Digital) who agree to certain time limitations on the registration with respect to such securities, in either case at a purchase price of no less than $3.00 per share of Common Stock and for aggregate consideration of no more than $15,000,000.

Further, pursuant to the terms of a Subscription, Purchase and Investment Agreement, dated as of September 18, 2013, by and among Walker Digital, Issuer and the investors party thereto (the “Investors”), Walker Digital covenanted to each of the Investors that it will not, from the Closing Date through the first anniversary of the Closing Date, sell any shares of Common Stock to any third party for a purchase price of less than $3.00 per share; provided that Walker Digital may transfer up to 400,000 shares of Common Stock to one of its affiliates for the sole purpose of such affiliate transferring such shares of Common Stock to certain of such affiliate’s former officers. Walker Digital anticipates that it will cause Issuer to be re-named Patent Properties, Inc. in the fourth quarter of 2013.
