(1) Unless otherwise provided in the articles of incorporation, a majority of the shares entitled to vote, represented in person or by proxy, shall constitute a quorum at a meeting of shareholders. If a quorum is present, the affirmative vote of the majority of the shares represented at the meeting at the time the vote is taken and entitled to vote on the subject matter shall be the act of the shareholders, unless the vote of a greater number or voting by classes is required by the Bank Act or the articles of incorporation.

(2) Once a share is represented at a meeting, it is deemed present for quorum purposes for the remainder of the meeting and for any adjournment of that meeting unless a new record date is or must be set for that adjourned meeting.
