(a) Unless otherwise provided in the articles or bylaws of the corporation and except for a vacancy created by the removal of a director, vacancies on the board may be filled by a majority of the directors then in office, whether or not less than a quorum, or by a sole remaining director. Unless the articles or a bylaw adopted with approval of the outstanding shares provide that the board may fill vacancies occurring in the board by reason of removal of directors, the vacancies may be filled only by approval of the shareholders.

(b) The shareholders may elect a director to fill a vacancy not filled by the directors. An election by written consent to fill a vacancy requires the consent of a majority of the outstanding shares entitled to vote.

(c) If, after the filling of a vacancy by the directors, the directors who have been elected by the shareholders constitute less than a majority of the directors, a holder or holders of an aggregate of 10 percent or more of the shares outstanding at the time may call a special meeting of shareholders under AS 10.06.405 to elect the entire board. The term of office of a director terminates upon the election and qualification of a successor.

(d) Notwithstanding AS 10.06.453(e), a director may resign effective upon giving written notice to the chairman of the board, the president, the secretary, or the board of directors of the corporation, unless the notice specifies a later time for the effectiveness of the resignation. If the resignation is effective at a future time, a successor may be elected to take office when the resignation becomes effective.
