Quorum and voting requirements for voting groups.

Shares entitled to vote as a separate voting group may take action on a matter at a meeting only if a quorum of those shares exists with respect to that matter. Unless the articles of incorporation provides otherwise, a majority of the votes entitled to be cast on the matter by the voting group constitutes a quorum of that voting group for action on that matter. Once a share is represented for any purpose at a meeting, it shall be 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. If a quorum exists, action on a matter, other than the election of directors, by a voting group shall be approved if the votes cast within the voting group favoring the action exceed the votes cast opposing the action, unless the articles of incorporation require a greater number of affirmative votes. An amendment of articles of incorporation adding, changing, or deleting a quorum or voting requirement for a voting group greater than specified in subsection (a) or (c) of this section shall be governed by § 29-305.27. The election of directors shall be governed by § 29-305.28.
