Stockholders Rights Plan	12. STOCKHOLDER RIGHTS PLAN On January 28, 2016, the Company announced that the Board of Directors had adopted a stockholders rights plan (the “Rights Plan”). To implement the Rights Plan, the Board of Directors declared a dividend distribution of one right for each outstanding share of Company common stock, par value $.01 per share, to holders of record of the shares of common stock at the close of business on January 29, 2016. Each right entitled the registered holder to purchase from the Company one one-thousandth of a share of preferred stock, par value $.01 per share. The rights were distributed as a non-taxable dividend and were set to expire on January 29, 2026. The rights were evidenced by the underlying Company common stock, and no separate preferred stock purchase rights certificates had been distributed. The rights to acquire preferred stock were not immediately exercisable and would have become exercisable only if a person or group, other than Exempt Persons (as defined in the Rights Plan agreement), acquired or commenced a tender offer for 9.8% or more of the Company’s common stock. If a person or group, other than an Exempt Person, acquires or commences a tender offer for 9.8% or more of the Company’s common stock, each holder of a right, except the acquirer, would have been entitled, subject to the Company’s right to redeem or exchange the right, to exercise, at an exercise price of $12, the right to purchase one one-thousandth of a share of the Company’s newly created Series A Participating Preferred Stock, or the number of shares of Company common stock equal to the holder’s number of rights multiplied by the exercise price and divided by 50% of the market price of the Company’s common stock on the date of the occurrence of such an event. The Company’s Board of Directors could terminate the Rights Plan at any time or redeem the rights, for $0.01 per right, at any time before a person acquired 9.8% or more of the Company’s common stock. This Rights Plan replaced the Company’s stockholders rights plan dated November 25, 2015, which expired on its own terms on March 24, 2016. On October 20, 2017, the Company and American Stock Transfer & Trust Company, LLC, as rights agent (the “Rights Agent”), entered into an amendment (the “Rights Plan Amendment”) to the Company’s stockholders rights plan, dated as of January 29, 2016, between the Company and the Rights Agent (“Rights Plan”). The Rights Plan Amendment accelerated the expiration of the Company’s preferred share purchase rights under the Rights Plan from the Close of Business (as such term is defined in the Rights Plan) on January 29, 2026 to the Close of Business on October 20, 2017, and the Rights Plan was terminated at such time. At the time of the termination of the Rights Plan, all of the rights distributed to holders of the Company’s common stock pursuant to the Rights Plan expired.

To implement the Rights Plan, the Board of Directors declared a dividend distribution of one right for each outstanding share of Company common stock, par value $.01 per share, to holders of record of the shares of common stock at the close of business on January 29, 2016. Each right entitled the registered holder to purchase from the Company one one-thousandth of a share of preferred stock, par value $.01 per share. The rights were distributed as a non-taxable dividend and were set to expire on January 29, 2026. The rights were evidenced by the underlying Company common stock, and no separate preferred stock purchase rights certificates had been distributed. The rights to acquire preferred stock were not immediately exercisable and would have become exercisable only if a person or group, other than Exempt Persons (as defined in the Rights Plan agreement), acquired or commenced a tender offer for 9.8% or more of the Company’s common stock. If a person or group, other than an Exempt Person, acquires or commences a tender offer for 9.8% or more of the Company’s common stock, each holder of a right, except the acquirer, would have been entitled, subject to the Company’s right to redeem or exchange the right, to exercise, at an exercise price of $12, the right to purchase one one-thousandth of a share of the Company’s newly created Series A Participating Preferred Stock, or the number of shares of Company common stock equal to the holder’s number of rights multiplied by the exercise price and divided by 50% of the market price of the Company’s common stock on the date of the occurrence of such an event. The Company’s Board of Directors could terminate the Rights Plan at any time or redeem the rights, for $0.01 per right, at any time before a person acquired 9.8% or more of the Company’s common stock.
