On July 24, 2013, Spherix Incorporated (the “Company”) closed on the acquisition of a group of patents in the mobile communication sector (the “Purchased Patents”) from Rockstar Consortium US LP, a Delaware limited partnership (“Rockstar”).  In consideration for the Purchased Patents, the Company paid certain consideration to Rockstar, including 176,991 shares of the Company’s Common Stock (the “Shares”).  The Shares are subject to a lock-up agreement, subject to certain leak-out provisions, which shall expire on the earlier of (i) six months from the issuance of the Shares and (ii) the date that the Company’s Common Stock achieves a trading volume of at least 50,000 shares per day and a closing price of at least $13 per share for a period of five consecutive days.  The Company has agreed to file a registration statement covering the resale of the Shares with the Securities and Exchange Commission (the “SEC”) within sixty (60) days of the closing of the acquisition and to use its best efforts to cause such registration statement to be declared effective by the SEC within one hundred and twenty (120) days from closing.  Rockstar will also be entitled to receive a percentage of future profits after recovery of patent monetization costs and an initial priority return on investment to the Company.
