Oregon Revised Statutes Corporations and Partnerships § 62.285

(1) Regular or special meetings of the board may be held either within or without this state.

(2) Regular meetings of the board may be held with or without notice as prescribed in the bylaws. Special meetings of the board shall be held upon such notice as is prescribed in the bylaws. Attendance of a director at a meeting shall constitute a waiver of notice of the meeting except where a director attends a meeting for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened.

(3) Unless the bylaws provide otherwise, the purposes of any meeting of the board need not be specified in the notice or waiver of notice of the meeting.

(4) Unless a greater number is required in the bylaws, a majority of the number of directors fixed by or determined pursuant to the bylaws, or in the absence of a bylaw fixing the number of directors, then of the number stated in the articles, shall constitute a quorum for the transaction of business. Unless a greater number is required in the bylaws, an act of the majority of the directors present at a meeting at which a quorum is present is the act of the board.
