Rights Agreement	9. RIGHTS AGREEMENT On May 18, 2016, the Board of Directors (the “Board”) of the Company entered into a rights agreement (the “Rights Agreement”) with Computershare Trust Company, N.A. and declared a dividend of one preferred share purchase right (a “Right”) for each outstanding share of common stock, $0.01 par value per share, of the Company. The dividend was payable upon the close of business on May 31, 2016 to the stockholders of record upon the close of business on that date. The Board adopted the Rights Agreement to protect stockholder value by attempting to reduce the risk that the Company’s ability to use its net operating losses to reduce potential future federal income tax obligations may become substantially limited. Each Right entitles the registered holder to purchase from the Company one one-hundredth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share (“Preferred Shares”), of the Company at a price of $13.86 per one one-hundredth of a Preferred Share, subject to adjustment. As a result of the Rights Agreement, any person or group that acquires beneficial ownership of 4.99% or more of the Company’s common stock without the approval of the Board would be subject to significant dilution in the ownership interest of that person or group. In connection with the entry into the Rights Agreement, on May 18, 2016, the Company filed with the Secretary of State of the State of Delaware an Amended and Restated Certificate of Designation of Series A Junior Participating Preferred Stock to create the Preferred Shares.
