Note 6 — Shareholder Rights Plan

During fiscal year 1997, the Company’s Board of Directors approved the adoption of a shareholder rights plan (the “Shareholder Rights Plan”). The Shareholder Rights Plan provides for a dividend distribution to the Company’s shareholders of one preferred stock purchase right for each outstanding share of the Company’s common stock held by such shareholder (as used in this Note, the “right” or the “rights”), only in the event of certain takeover-related events. In November 2008, the Company’s Board of Directors approved an amendment to the Shareholder Rights Plan to extend the expiration date of the rights to February 10, 2022.

The rights are designed to assure that all shareholders receive fair and equal treatment in the event of a proposed takeover of the Company, and to encourage a potential acquirer to negotiate with the Company’s Board of Directors prior to attempting a takeover. The rights are not exercisable until the occurrence of certain takeover-related events, at which time they can be exercised at an exercise price of $118 per share of common stock which carries the right, subject to subsequent adjustments. The rights trade with the Company’s common stock.

Generally, the Shareholder Rights Plan provides that if a person or group acquires 15% or more of the Company’s common stock without the approval of the Company’s Board of Directors, subject to certain exceptions, the holders of the rights, other than the acquiring person or group, would, under certain circumstances, have the right to purchase additional shares of the Company’s common stock having a market value equal to two times the then-current exercise price of the right.

The Company’s Board of Directors may exchange or redeem the rights under certain conditions.
