Pursuant to the Rights Agreement, the Board declared a dividend distribution of one Right (a “Right”) for each outstanding share of Company Common Stock, par value $0.01 per share (the “Common Stock”) to shareholders of record at the close of business on May 6, 2013, which date will be the record date, and for each share of Common Stock issued (including shares distributed from treasury) by the Company thereafter and prior to the Distribution Date (as described below and defined in the Rights Agreement). Each Right entitles the registered holder, subject to the terms of the Rights Agreement, to purchase from the Company one one-thousandth of a share of Series A Participating Preferred Stock, $0.01 par value per share (the “Series A Preferred Stock”), at an exercise price of $4.00 per one one-thousandth of a share of Series A Preferred Stock, subject to adjustment.
