(c) The provisions of this section shall not apply to a control share acquisition to which the provisions of this article otherwise apply if, at the time the issuing public corporation receives an acquiring person statement with respect to the control share acquisition, the articles of incorporation or bylaws of the issuing public corporation contain a provision expressly electing not to be governed by this section.
