Rights Agreement	16. 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 paid at close of business on May 31, 2016 to the stockholders of record on that date. The Board adopted the Rights Agreement to protect stockholder value by protecting the Company’s ability to capture the value of its net operating losses used to reduce potential future federal income tax obligations. The Rights Agreement was approved by the Company’s stockholders at the 2017 annual meeting of stockholders. On May 6, 2019 the Board approved and we entered into a First Amendment to Rights Agreement between the Company and ComputerShare Trust Company, N.A., as rights agent. The Amendment, among other things, (i) extends the final expiration date (as defined in the Rights Agreement) from May 18, 2019 to May 18, 2022; (ii) changes the initial purchase price (as defined in the Rights Agreement) from $13.86 to $13.39; and (iii) increases the period pursuant to which the Board has to consider an exemption request (as defined in the Rights Agreement) from ten business days to 20 business days. The Rights Agreement will expire on the earliest of (i) May 18, 2022, (ii) the time at which the Rights are redeemed or exchanged, as provided for in the Rights Agreement, (iii) the repeal of Section 382 of the Internal Revenue Code of 1986, as amended, if the Board determines that the Rights Agreement is no longer necessary for the preservation of the Company’s NOLs, and (iv) the beginning of a taxable year of the Company to which the Board determines that no NOLs may be carried forward. We adopted the Rights Agreement to protect stockholder value by attempting to diminish the risk that our ability to use our NOLs 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 $13.39 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 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.
