2011 ORS § 62.555¹
Right to amend articles of incorporation

(1) A cooperative may amend its articles from time to time in any and as many respects as may be desired, so long as its articles as amended contain only such provisions as might be lawfully contained in original articles at the time of making the amendment, and, if a change in shares or the rights of shareholders or members, or an exchange, reclassification or cancellation of shares or rights of shareholders or members is to be made, such provisions as may be necessary to effect the change, exchange, reclassification or cancellation.

(2) Amendments to the articles shall be made in the following manner:

(a) The board shall adopt a resolution setting forth the proposed amendment and directing that it be submitted to a vote at a meeting of the members of the cooperative, which may be either an annual or a special meeting.

(b) Written or printed notice setting forth the proposed amendment or a summary of the changes to be effected thereby shall be given to each member of record within the time and in the manner provided in ORS 62.255 (Meetings of members) for the giving of notice of meetings of members. If the meeting is an annual meeting, the proposed amendment or the summary may be included in the notice of the annual meeting.

(c) At the meeting a vote of the members shall be taken on the proposed amendment. The proposed amendment is adopted upon receiving the affirmative vote of a majority of the member votes cast thereon, unless shareholders are entitled by ORS 62.560 (Shareholder voting on amendments to articles) to vote on the proposed amendment, in which event the proposed amendment is adopted upon receiving the approval of shareholders as specified in ORS 62.560 (Shareholder voting on amendments to articles), as well as the affirmative vote of a majority of member votes cast thereon. Any number of amendments may be submitted to the members and voted upon by them at one meeting. [1957 c.716 §38]
