Vote Required and Method of Counting Votes
The presence at the Annual Meeting – in person or by duly authorized proxy – of a majority of all the stock issued and outstanding and having voting power shall constitute a quorum for the transaction of business. Abstentions are counted as shares present at the meeting.
Item 1: Election of Directors
In an uncontested director election, each director nominee shall be elected by the affirmative vote of the majority of the votes cast with respect to that director’s election at any meeting for the election of directors at which a quorum is present. A majority of votes cast means that the number of shares voted “for” a director’s election exceeds 50 percent of the number of votes cast with respect to that director’s election. Votes cast include votes “against,” but exclude “abstentions” and “broker nonvotes” with respect to that director’s election. Pursuant to the Company’s Bylaws, an incumbent director that is not elected by a majority vote will tender his or her resignation subject to acceptance by the Board. The Company’s Certificate of Incorporation does not provide for cumulative voting. Proxies signed, dated and returned unmarked will be voted FOR all of the nominees.
