A corporation must have at least one director, and may provide in its articles of incorporation or in its bylaws for a fixed number of directors or a variable number of directors, and for the manner in which the number of directors may be increased or decreased. Unless otherwise provided in the articles of incorporation, directors need not be stockholders.
