Any shareholder desiring to nominate any person for election as a director of the corporation shall deliver with such notice a statement in writing setting forth the name of the person to be nominated, the number and class of all shares of each class of stock of the Corporation beneficially owned by such person, the information regarding such person required by paragraphs (a), (e) and (f) of Item 401 of Regulation S-K adopted by the Securities and Exchange Commission (or the corresponding provisions of any regulation subsequently adopted by the Securities and Exchange Commission applicable to the Corporation), such person's signed consent to serve as a director of the corporation if elected, such shareholder's name and address and the number and class of all shares of each class of stock of the corporation beneficially owned by such shareholder. As used herein, shares "beneficially owned" shall mean all shares as to which such person, together with such person's affiliates and associates (as defined in Rule 12b-2 under the Securities Exchange Act of 1934), may be deemed to beneficially own pursuant to Rules 13d-3 and 13d-5 under the Securities Exchange Act of 1934, as well as all shares as to which such person, together with such person's affiliates and associates, has the right to become the beneficial owner pursuant to any agreement or understanding, or upon the exercise of warrants, options or rights to convert or exchange (whether such rights are exercisable immediately or only after the passage of time or the occurrence of conditions). The person presiding at the meeting, in addition to making any other determinations that may be appropriate to the conduct of the meeting, shall determine whether such notice has been duly given and shall direct that proposals and nominees not be considered if such notice has not been given. /s/ Dale M.
