Shareholder Rights Plan	22. Shareholder Rights Plan The Company has a shareholder rights plan, under which each share of common stock carries with it an associated right (a “Right”). Each Right entitles the holder to purchase 1/100 of a share of Series A No Par Preferred Stock at a purchase price of $60, subject to adjustment. The Rights do not have voting or dividend rights and, until they become exercisable, have no dilutive effect on the Company’s earnings. The Rights expire on May 18, 2019 and may be redeemed by the Company for $0.001 per Right. The Rights are not presently exercisable and will only become exercisable following the occurrence of certain specified events, including the following: (a) a person or group acquires or commences a tender offer that would result in beneficial ownership of 15 percent or more of outstanding common stock; (b) any person becomes a beneficial owner of 10 percent or more of outstanding common stock and is determined by the Board of Directors to be an “Adverse Person”; or (c) a person or group acquires, or obtains the right to acquire, 15 percent of the outstanding Common Stock. If either of the events described in clause (b) or (c) above occurs, each Right will thereafter entitle its holder to receive, upon exercise and in lieu of Series A No Par Preferred Stock, Common Stock (or in certain circumstances, cash, property or other securities of the Company) having a value equal to twice the exercise price of the Right. If, after the Rights become exercisable as described above, the Company is acquired in a merger or other business combination, each Right will thereafter entitle its holder to receive, upon exercise and in lieu of capital stock of the Company, common stock of the acquiring company having a value equal to twice the exercise price of the Right.
