If the articles of incorporation authorize dividing the shares into classes, the articles may also authorize the election of all or a specified number of directors by the holders of one or more authorized classes of shares. A class or classes of shares entitled to elect one or more directors shall be a separate voting group for the purposes of the election of directors.
