Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On May 12, 2016, the Company held its 2016 Annual Meeting of Stockholders (“Annual Meeting”) at which the stockholders elected each of James K. Bass, Thomas T. Edman, Tang Chung Yen, Tom and Dov S. Zakheim to serve as Class I directors for a term expiring in 2019.

The stockholders also considered and approved amendments (the “Plan Amendments”) to the Company’s 2014 Incentive Compensation Plan (the “2014 Plan”).

The Plan Amendments became effective upon such stockholder approval. The Plan Amendments, among other things, increase the number of shares of the Company’s common stock available for issuance thereunder from 4,000,000 to 9,000,000. The Plan Amendments also limit the “fair market value” of any grants made to non-employee directors to $500,000, provide for a minimum vesting period of no less than one year and eliminate the ability for the Company to provide a loan to an award participant to purchase awards.

A summary of the amended 2014 Plan is set forth in the Company’s definitive proxy statement for the Annual Meeting filed with the Securities and Exchange Commission on March 31, 2016. That summary and the foregoing description of the Plan Amendments are qualified in their entirety by reference to the text of the amended 2014 Plan, which is filed as Exhibit 10.1 hereto and incorporated by reference herein.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

The stockholders also considered and approved at the Annual Meeting an amendment to the Company’s Second Amended and Restated Articles of Incorporation (the “Amendment”). The Amendment increases the number of authorized shares of Common Stock of the Company from 200 million shares to 300 million shares. On May 13, 2016, the Company filed the Amendment with the Secretary of State of Delaware

The foregoing description of the Amendment is only a summary and does not purport to be complete and is qualified in its entirety by the actual Amendment, a copy of which is filed as Exhibit 3.1 hereto and is incorporated by reference herein.

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

At the Annual Meeting, of the 100,162,825 shares of common stock outstanding on the record date, 88,746,787 shares were present at the meeting in person or by proxy, representing approximately 88.6% of the total outstanding shares eligible to vote.
