                                By-Law Amendments

     The By-Laws of the Corporation may be amended by the Board of Directors.

                                  ARTICLE VII
                                Indemnification

     The Corporation shall indemnify every person who is or was a Director of
the Corporation against all liability to the fullest extent permitted by Chapter
37 of the Act, provided


                                      -2-


that such person is determined in the manner specified by Chapter 37 of the Act
to have met the standard of conduct specified in Chapter 37 of the Act. The
Corporation shall, to the fullest extent permitted by Chapter 37 of the Act, pay
for or reimburse the reasonable expenses incurred by every person who is or was
a Director who is a party to a proceeding in advance of final disposition of the
proceeding, in the manner specified by Chapter 37 of the Act. The Corporation
shall indemnify and advance expenses to every person who is or was an Officer of
the Corporation to the same extent as if such person were a Director of the
Corporation (All such persons who are or were directors or officers of the
Corporation are referred to as "Indemnitee"). The indemnification and advance of
expenses for Indemnitees shall apply to service in the Indemnitee's official
capacity with the Corporation, and to service at the Corporation's request,
while also acting in an official capacity with the Corporation, as a director,
officer, partner, trustee, employee, or agent of another foreign or domestic
corporation, partnership, joint venture, trust, employee benefit plan, or other
enterprise, whether for profit or not. All references in this paragraph to
Chapter 37 of the Act shall be deemed to include any amendment or successor to
the Act. When a word or phrase used in this paragraph is defined in Chapter 37
of the Act, such word or phrase shall have the same meaning in this paragraph
that it has in Chapter 37 of the Act. Nothing contained in this paragraph shall
limit or preclude the exercise of any right relating to indemnification or
advance of expenses to any Indemnitee or the ability of the Corporation to
otherwise indemnify or advance expenses to any Indemnitee. These provisions
shall be binding upon any successor to the Corporation so that each Indemnitee
shall be in the same position with respect to any resulting, surviving, or
succeeding entity as he or she would have been had the separate legal existence
of the Corporation continued; provided, that unless expressly provided or agreed
otherwise, this sentence shall be applicable only to Indemnitees acting in an
official capacity or in another capacity set forth above prior to termination of
the separate legal existence of the Corporation. These provisions shall be
deemed to create a contract right for the benefit of every Indemnitee if (i) any
act or omission complained of in a proceeding against the Indemnitee, (ii) any
portion of a proceeding, or (iii) any determination or assessment of liability,
occurs while the provisions are in effect. If any word, clause, or sentence of
the provisions regarding indemnification or advancement of expenses shall be
held invalid as contrary to law or public policy, it shall be severable and the
provisions remaining shall not be otherwise affected. If any Court holds any
word, clause, or sentence of this paragraph invalid, the Court is authorized and
empowered to rewrite these provisions to achieve their purpose to the extent
possible. All references in this paragraph to any Indemnitee shall include the
heirs, estate, executors, administrators and personal representatives of such
person.
