Any vacancy occurring in the Board of Directors and any directorship to be filled by reason of an increase in the number of directors may be filled by the affirmative vote of a majority of the members of the Board of Directors, though less than a quorum of the board, unless otherwise provided in Section 6-701, in the case of public purpose corporations, or the articles of incorporation or the bylaws provide that a vacancy or directorship so created shall be filled in some other manner, in which case, such provision shall control. A director elected or appointed, as the case may be, to fill a vacancy shall be elected or appointed for the unexpired term of his predecessor in office. ONCA 21-27, eff. Apr. 6, 2021.
