Nothing contained in this Act is intended to alter or codify the business judgment rule as developed by the courts of this State or to limit its further development.  

2.  Exceptions.  This Act does not apply to:  

3.  Validity of articles or bylaws.  The validity of any provision of the articles of incorporation or the bylaws of a corporation existing on July 1, 2003 must be determined with reference to the law that was in effect at the time when the provision was adopted or with reference to this Act, whichever supports the validity of such provision. A provision of a corporation's articles of incorporation or bylaws that was valid under the law in existence at the time the same was adopted remains in effect, notwithstanding a contrary provision of this Act, until repealed or amended by voluntary act of the corporation, but any amendment to such a provision must be adopted by the procedures set out in this Act and must, as amended, conform to the requirements of this Act.
