Proposal 2 would amend the Amended and Restated Certificate of Incorporation to initiate the declassification of the Board and eliminate the provisions requiring the election of directors by plurality vote so that the voting standard for elections may be modified in the bylaws. If the amendment is approved, then commencing with the class of directors standing for election at the 2011 annual meeting of stockholders our directors will stand for election for one-year terms; directors elected or appointed prior to the 2011 annual meeting will continue to serve their full three-year terms. The amendment also provides that directors serving one-year terms may be removed from office with or without cause by 75% of the voting power of the stock entitled to vote thereon and provides that directors serving the remainder of three-year terms may be removed only for cause by 75% of the voting power of the stock entitled to vote thereon. This summary is qualified by reference to Proposal 2 set forth in the proxy statement for the 2010 annual stockholders meeting and Annex A thereto, which sets forth the full text of the proposed amendment. You are urged to read Annex A in its entirety by accessing a copy of such proxy materials by following the instructions on this notice.
