Stockholder rights plan				Under the Rights Plan, the Rights would be distributed upon the earlier to occur of (i) the tenth business day following a public announcement indicating that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired beneficial ownership of 10.0% or more of the Company’s outstanding common stock or such earlier date as a majority of the Board of Directors becomes aware of such acquisition or (ii) the tenth business day (or such later date as the Board of Directors may determine prior to such time as any person or group becomes an Acquiring Person) following the commencement of, or first public announcement of an intention to commence, a tender or exchange offer the consummation of which would result in a person or group becoming the beneficial owner of 10.0% or more of the then outstanding common stock (the “Distribution Date”). The Rights are not exercisable until the Distribution Date. After the Distribution Date, each Right will entitle the holder to purchase from the Company one share of common stock at a purchase price of $24.00 per common share (the “Purchase Price”), subject to adjustment. Following the existence of an Acquiring Person, all Rights that are or were beneficially owned by any Acquiring Person will be null and void. If a person or group becomes an Acquiring Person (with certain limited exceptions), each holder of a Right will thereafter have the right to receive, upon exercise, common stock (or, in certain circumstances, other securities of the Company, cash or assets of the Company) having a value equal to two times the Purchase Price. Also, in the event at any time after a person becomes an Acquiring Person, if the Company consolidates or merges with any other person or engages in other specified transactions, proper provision will be made so that each holder of a Right will thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the Purchase Price. At any time after any person or group becomes an Acquiring Person and prior to the acquisition by such person or group of 50.0% or more of the outstanding common stock, the Board of Directors may exchange the Rights (other than Rights owned by such person or group which have become void), in whole or in part, at an exchange ratio of one share of common stock per Right (subject to adjustment).
