(805 ILCS 105/108.10) (from Ch. 32, par. 108.10)
    Sec. 108.10. Number, election and resignation of directors.
    (a) The board of directors of a corporation shall consist of three or more directors. The number of directors shall be fixed by the bylaws, except the number of initial directors shall be fixed by the incorporators in the articles of incorporation. In the absence of a bylaw fixing the number of directors, the number shall be the same as that fixed in the articles of incorporation. The number of directors may be increased or decreased from time to time by amendment to the bylaws.
    (b) The bylaws may establish a variable range for the size of the board by prescribing a minimum and maximum (which may not be less than 3 or exceed the minimum by more than 5) number of directors. If a variable range is established, unless the bylaws otherwise provide, the number of directors may be fixed or changed from time to time, within the minimum and maximum, by the directors without further amendment to the bylaws.
    (c) The terms of all directors expire at the next meeting for the election of directors following their election unless their terms are staggered under subsection (e). The term of a director elected to fill a vacancy expires at the next annual meeting of the members entitled to vote at which his or her predecessor's term would have expired or in accordance with Section 108.30 of this Act. The term of a director elected as a result of an increase in the number of directors expires at the next annual meeting of members entitled to vote unless the term is staggered under subsection (e).
    (d) Despite the expiration of a director's term, he or she continues to serve until the next meeting of members or directors entitled to vote on directors at which directors are elected. An amendment to the bylaws decreasing the number of directors or eliminating the position of a director elected or appointed by persons or entities other than the members may shorten the terms of incumbent directors; provided, however, such amendment has been approved by the party with the authority to elect or appoint such directors.
    (e) The articles of incorporation or the bylaws may provide that directors may be divided into classes and the terms of office of several classes need not be uniform. Each director shall hold office for the term for which he is elected and until his successor shall have been elected and qualified.
    (f) If the articles of incorporation or bylaws authorize dividing the members into classes, the articles or bylaws may also authorize the election of all or a specified number or percentage of directors by one or more authorized classes of members.
    (g) A director may resign at any time by written notice delivered to the board of directors, its chairman, or to the president or secretary of the corporation. A resignation is effective when the notice is delivered unless the notice specifies a future date. The pending vacancy may be filled before the effective date, but the successor shall not take office until the effective date.
