Item 5.02.    Compensatory Arrangements of Certain Officers.

On May 14, 2014, the Board of Directors of Entropic Communications, Inc., or Entropic, approved an amendment to the Change of Control Agreements, or the Amendment, between Entropic and the following named executive officers of Entropic: David Lyle, Entropic’s Chief Financial Officer, Michael Farese, Ph.D., Entropic’s Chief Technical Officer, F. Matthew Rhodes, Entropic’s Senior Vice President, Global Marketing, and Charlie Lesko, Entropic’s Senior Vice President, Worldwide Sales. The Amendment will provide for full acceleration of vesting of restricted stock units, stock options and other outstanding equity awards in the event the applicable executive officer is terminated without cause or resigns for good reason within one year following a change of control transaction. Prior to the Amendment, vesting only accelerated as to that portion of restricted stock units, stock options and other outstanding equity awards held by the applicable executive officer which were scheduled to vest during the 24 months following a qualifying termination of employment or resignation of the applicable executive officer. In addition, the Amendment will extend the period of time each applicable executive officer may receive COBRA benefits paid for by Entropic, from six months to twelve months following a qualifying termination of employment or resignation. The Amendment was approved on the recommendation of the Compensation Committee of the Board of Directors as part of its periodic review of the competitiveness of Entropic’s compensation plans, and the changes are designed to bring Entropic’s change of control provisions into alignment with industry practices for Entropic’s peer group.

A copy of the form of Amendment will be filed as an exhibit to Entropic’s Quarterly Report on Form 10-Q for the quarter ending June 30, 2014.

Item 5.07.    Submission of Matters to a Vote of Security Holders.

Item 8.01.    Other Events.

        On May 14, 2014, the Compensation Committee of the Board of Directors of Entropic granted performance-based restricted stock unit awards, or PSUs, to executive officers of Entropic. Entropic suspended its annual cash bonus program for calendar year 2014 for its executive officers, and replaced it with a three-year relative total shareholder return program, or RTSR Program, that requires certain performance hurdles to be achieved in order for the applicable executive officers to earn any portion of the PSUs. Entropic’s Compensation Committee believes that the RTSR Program will provide a performance-based incentive compensation plan that directly aligns management’s objectives with those of Entropic’s stockholders. Earning of any equity issued under the RTSR Program will be based on Entropic’s stock price performance relative to the stock price performance of the S&P Semiconductor Select Index over a three-year period, with one-and two-year interim measurements.
