Sarvary, dated as of June 30, 2008 (the “Employment Agreement”), the Company and Mr. Sarvary mutually agreed to amend the Employment Agreement (the “Amendment”) to add two subsections to the Employment Agreement to address technical issues on the timing of various severance and separation payments to be paid to Mr. Sarvary if and when he separates from the Company.

On May 27, 2015, the Company sent a letter to Mr. Sarvary confirming that the Company was terminating Mr. Sarvary’s employment under the Employment Agreement not for Cause (as defined in the Employment Agreement), effective May 31, 2015. Mr. Sarvary’s departure will be governed by the terms of the Employment Agreement and the Amendment and other related compensation and benefit plans. In addition to the foregoing, on May 27, 2015 the Company entered into a letter agreement with Mr. Sarvary. The letter agreement confirmed Mr. Sarvary’s termination; Mr. Sarvary provided a general release and waiver of claims; and the Company agreed to provide Mr. Sarvary with outplacement services and reimburse legal expenses, a mutual non-disparagement provision and certain other provisions relating to his departure.

Adoption of Retention Program

Additionally, in connection with recent changes in Board composition and the announced search for a new CEO, the Board approved on May 30, 2015 a retention program for certain members of senior management (the “Retention Program”) in order to help ensure stability in the senior management team over the next year and create additional incentives to meet performance targets for 2015. The Retention Program provides that the Company will make retention bonus payments to certain members of senior management ( the “Senior Executives”) if two requirements are met: (i) the Company meets an adjusted EBITDA threshold (as defined in the documents creating the Retention Program) for 2015 of $444 million (representing the consensus analysts’ estimate for 2015 adjusted EBITDA as of May 27, 2015) and (ii) the particular Senior Executive is still employed at May 31, 2016 or was terminated by the Company on or prior to that date, other than for “Cause”, or the Senior Executive terminated his or her employment on or before May 31, 2016 for “Good Reason” (with “Cause” and “Good Reason” having definitions based on the terms of the Senior Executive’s employment agreement or the Company’s Severance and Retention Plan dated as of March 18, 2013 which was filed as Exhibit 10.2 to Form 8-K filed with the SEC on October 23, 2013).
