Majority Voting for Uncontested Elections of Directors

Our Bylaws provide for majority voting in an uncontested election; a nominee for our Board will be elected if a majority of the votes cast are in favor of such nominee’s election (meaning that the number of votes cast “for” a nominee exceeds the number of votes cast “against” a nominee). In a contested election, directors will be elected by a plurality of the votes of the Shares represented in person or by proxy at any meeting of shareholders held to elect directors and entitled to vote on such election of directors. In the event that a director nominee fails to receive an affirmative majority of the votes cast in an uncontested election, the nominee will not be elected and our Board, within its powers, may take any appropriate action, including decreasing the number of directors or filling a vacancy.

Under Delaware law and our Bylaws, if a quorum exists at the meeting, the affirmative vote of a majority of the votes properly cast at the meeting is required for the election of Class I directors, as described in this Proxy Statement under the heading “Majority Voting for Uncontested Elections of Directors.”
