Paul Ryan, Acacia’s current Chief Executive Officer and a director, has announced his intent to retire and will accordingly resign as Chief Executive Officer and as a director of Acacia, effective July 31, 2013. Mr. Ryan commented, "In anticipation of my retirement I want to thank all of the very talented employees who have built Acacia into a premier patent licensing company. Acacia has a very deep and experienced management team and I along with our Executive Chairman, Chip Harris, and all of our board of directors are very confident that with Matthew Vella as CEO, the company will continue to build its leadership role in the industry." Mr. Vella joined Acacia in November 2006 as Vice President. He was appointed Senior Vice President in October 2007, Executive Vice President in October 2011 and President in September 2012. Prior to joining Acacia, Mr. Vella was Senior Intellectual Property Counsel for ATI Research, Inc., Lead Patent License Counsel for Nortel Networks, Inc. and Counsel for Nortel Networks Corporation. Executive Chairman, Chip Harris, commented, "Paul and I have worked together for the last 13 years and we have added many highly talented individuals with expertise in the patent licensing business to the Acacia team. We started working on this succession plan over 18 months ago. Following Paul's 68th birthday, this new management structure is the culmination of that process. Paul was instrumental in Acacia's success and he will be sorely missed by our shareholders, employees and patent partners. I look forward to having the same type of relationship with Matt Vella as I did with Paul. Paul and I and all of the members of the board of directors have every confidence that Matt has the leadership skills and expertise to assume this new role."
