Committees of board of directors: Designation; powers; membership

1. Unless it is otherwise provided in the articles of incorporation, the board of directors may designate one or more committees which, to the extent provided in the resolution or resolutions or in the bylaws of the corporation, have and may exercise the powers of the board of directors in the management of the business and affairs of the corporation. 2. Each committee must include at least one director. Unless the articles of incorporation or the bylaws provide otherwise, the board of directors may appoint natural persons who are not directors to serve on committees. 3. The board of directors may designate one or more directors as alternate members of a committee to replace any member who is disqualified or absent from a meeting of the committee. The bylaws of the corporation may provide that, unless the board of directors appoints alternate members pursuant to this subsection, the member or members of a committee present at a meeting and not disqualified from voting, whether or not the member or members constitute a quorum, may unanimously appoint another member of the board of directors to act at the meeting in the place of an absent or disqualified member of the committee.
