Special members’ meetings of the members may be called by any of the following:

 The cooperative shall give notice of a special members’ meeting by mailing the special members’ meeting notice to each member personally at the person‘s last known post office address, or by another process determined by the board if the member is to vote by an alternative voting method as approved by the board and agreed to by the member individually or the members generally. For a member that is an entity, the notice mailed, or delivered by another process for vote by an alternative voting method, shall be to an officer of the entity. The special members’ meeting notice shall state the time, place, and purpose of the special members’ meeting. The special members’ meeting notice shall be issued within ten days from and after the date of the presentation of a members’ petition, and the special members’ meeting shall be held within thirty days after the date of the presentation of the members’ petition.

 A member may waive notice of a meeting of members. A waiver of notice by a member entitled to notice is effective whether given before, at, or after the meeting, and whether given in writing, orally, or by attendance. Attendance by a member at a meeting is a waiver of notice of that meeting, except where the member objects at the beginning of the meeting to the transaction of business because the meeting is not lawfully called or convened, or objects before a vote on an item of business because the item cannot lawfully be considered at that meeting and does not participate in the consideration of the item at that meeting.
