Preferred stock rights, description	The Board of Directors of the Company declared a dividend of one preferred share purchase right (a “Right”) for each share of Common Stock, par value $0.01 per share (“Common Stock”), of the Company outstanding on August 29, 2018 (the “Record Date”) to the stockholders of record on that date. In connection with the distribution of the Rights, the Company entered into a Rights Agreement (the “Rights Agreement”), dated as of August 29, 2018, between the Company and Continental Stock Transfer & Trust Company, as Rights Agent. Each Right entitles the registered holder to purchase from the Company one one-hundredth of a share of Class A Preferred Stock, Series One, par value $0.01 per share (“Preferred Stock”), of the Company at a price of $24.78 per one one-hundredth of a share of Preferred Stock represented by a Right (the “Purchase Price”), subject to adjustment.					Each share of Preferred Stock will be entitled to receive, when, as and if declared by the Board of Directors, (a) cash dividends in an amount per share (rounded to the nearest cent) equal to 100 times the aggregate per share amount of all cash dividends declared or paid on the Common Stock and (b) a preferential quarterly cash dividend (the “Preferential Dividends”) in an amount equal to $50.00 per share of Preferred Stock less the per share amount of all cash dividends declared on the Preferred Stock pursuant to clause (a) of this sentence. Each share of Preferred Stock will entitle the holder thereof to 100 votes per share, voting together with the holders of the Common Stock as a single class, except as otherwise provided in the Certificate of Designations of Class A Preferred Stock Series One filed by the Company with the Delaware Secretary of State or the Company’s Amended and Restated Certificate of Incorporation, as amended, or Amended and Restated By-laws. In the event of any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case each outstanding share of Preferred Stock shall at the same time be similarly exchanged for or changed into the aggregate amount of stock, securities, cash and/or other property (payable in like kind), as the case may be, for which or into which each share of Common Stock is changed or exchanged, multiplied by 100. Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, (a) no distribution shall be made to the holders of shares of stock ranking junior to the Preferred Stock unless the holders of the Preferred Stock shall have received the greater of (i) $100 per share of Preferred Stock plus an amount equal to accrued and unpaid dividends and distributions thereon or (ii) an amount equal to 100 times the aggregate amount to be distributed per share to holders of the Common Stock, and (b) no distribution shall be made to the holders of stock ranking on a parity upon liquidation, dissolution or winding up with the Preferred Stock unless simultaneously therewith distributions are made ratably on the holders of the Preferred Stock and all other shares of such parity stock in proportion to the total amounts to which the holders of shares of Preferred Stock are entitled under clause (a)(i) of this sentence and to which the holders of such parity shares are entitled, in each case upon such liquidation, dissolution or winding up.
