How to change the association's articles of incorporation

(a) An association may amend its articles of incorporation by the affirmative vote of two-thirds of the members voting thereon at any regular meeting, or at a special meeting called for the purpose, or if the association permits its members to vote on the basis of patronage, by the affirmative vote of a majority of the members and of two-thirds of the patronage, voting thereon. A written or printed notice of the proposed amendment, and of the time and place of holding the meetings shall be delivered to each member, or mailed to the member's last known address as shown by the books of the association, at least thirty days prior to any such meetings. No amendment affecting the preferential rights of any outstanding stock shall be adopted until the written consent of the holders of two-thirds of the outstanding preference shares has been obtained. (b) After an amendment has been adopted, articles of amendment shall be certified and executed by the president or vice president and by the treasurer or secretary or assistant secretary, and filed as in the case of articles of incorporation, including the payment of fees.
