Voting to Elect Directors. When voting to elect directors, you have three options:
If a quorum is present at the Annual Meeting, the nine persons receiving the greatest number of votes will be elected to serve as directors. Therefore, any shares that are not voted or whose votes are withheld will not influence the outcome of the election of directors. You may not cumulate your votes for any one of the nominees.
