Stockholder Nominations and Proposals of Business for a Meeting

Section 2.15 and Section 9.01 have been revised and Section 2.16 has been added to (i) clarify that the procedures set forth in the By-Laws are the exclusive means for a stockholder to submit stockholder nominations and proposals of business, other than proposals governed by Rule 14a-8 of the federal proxy rules (which provides its own procedural requirements), (ii) increase the notice period governing the submission of stockholder nominations and proposals of business to not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year's annual meeting, (iii) expand the required disclosure regarding the stockholders making such proposals or nominations to include, among other things, all ownership interests, hedges, economic incentives (including synthetic or temporary stock ownership) and voting rights, and (iv) require a stockholder nominating an individual for election as a director to include in the notice certain biographical information about each director nominee as well as a questionnaire and representation signed and completed by each director nominee that requires the nominee to disclose any voting commitments the nominee may have with a third person and commit to comply with the Company's corporate governance standards, if elected.

Stockholder Action by Written Consent

Section 6.05(B) has been combined with and into Section 2.17, which has been added to explicitly require that (i) stockholders, to act by written consent, must request the Board of Directors of the Company to set a record date for stockholders entitled to consent, and (ii) such request must contain all information that such stockholder would be required to provide if such stockholder had been making a nomination or proposing business to be considered at a meeting of stockholders. The record date must be set within ten days of a request and must be no later than ten days after the Board of Directors acts.
