(1) In its bylaws, each cooperative shall provide for one or more regular member meetings annually. Either the board or such officers as are designated in the bylaws shall have the right to call a special meeting of the members at any time, and the president, or other officer designated in the bylaws, shall call a special meeting to be held within sixty days upon petition by ten percent of the total number of members stating the specific business to be brought before the meeting. The board or the person calling the special meeting shall determine the date, time, and place of the meeting.

(2) Written notice of all member meetings shall be mailed to each member at that member's last-known address or transmitted to each member in such other manner as may be provided in the bylaws at least ten days prior to the meeting. Notice of any special meeting shall include a statement of the purpose for the meeting. At all regular meetings of members of the cooperative, any and all lawful business may be brought before the meeting regardless of whether stated in the notice of the meeting; except that amendments to the articles or the bylaws of the cooperative or other action required to be stated in the notice of the meeting by this article shall not be subject to action unless notice thereof is stated in the notice of the meeting. At all special meetings of the members of the cooperative, business brought before the meeting shall be limited to the purpose stated in the notice.

(3) Actions taken or agreed to be taken during a member meeting shall not be invalidated on account of any member's failure to receive notice of a meeting if reasonable effort has been made to give notice in accordance with this section.

(4) Lawful actions or other membership votes may be taken by the cooperative in lieu of or without a member meeting if all members entitled to act or vote with respect to the action agree to that action by unanimous written consent.
