Warrant or Right, Reason for Issuance, Description |  |  | Rights PlanOn May 21, 2020, the Board declared a dividend of one right (“Right”) for each outstanding share of common stock to common stockholders of record at the close of business on June 1, 2020 (the “Rights Plan”). Each Right entitles the registered holder to purchase from us a unit consisting of one one-hundredth of a share (a “Fractional Share”) of Series A Junior Participating Preferred Stock, par value $0.01 per share, at a purchase price of $255.00 per Fractional Share, subject to adjustment. Initially, the Rights are attached to all outstanding shares of our common stock. The Rights will be separate from our common stock and a “Distribution Date” will occur, with certain exceptions, upon the earlier of (i) ten days following a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired, or obtained the right to acquire, beneficial ownership of 10% (or 20% in the case of a “13G Investor,” as defined in the Rights Plan) or more of the outstanding shares of our common stock, or (ii) ten business days following the commencement of a tender offer or exchange offer that would result in a person’s becoming an Acquiring Person. The Rights are not exercisable until the Distribution Date and will expire at the close of business on May 20, 2021, unless earlier redeemed or exchanged by us. If the rights become exercisable, each holder other than the Acquiring Person (and certain related parties) will be entitled to acquire shares of our common stock at a 50% discount or we may exchange each right held by such holders for one share of common stock. |
