reason of the death, resignation or removal of a director) may be filled by
a majority vote of the directors then in office although less than a

in good faith or that involve intentional misconduct or a knowing violation of
law, (iii) for a violation of Section 551(l) of the Michigan Business
Corporation Act, and (iv) for any transaction from which the director derived
an improper personal benefit.  If the Michigan Business Corporation Act is
amended after approval by the shareholders of this Article VII to authorize
corporate action further eliminating or limiting the personal liability of
directors, then the liability of a director shall be eliminated or limited to
the fullest extent permitted by the Michigan Business Corporation Act, as so
amended.  No amendment to or repeal of this Article VII, and no modification to
its provisions by law, shall apply to, of have any effect upon, the liability
or alleged liability of any director of the Corporation for or with respect to
any acts or omissions of such director occurring prior to such amendment,

attorneys' fees), judgements, penalties, fines and amounts paid in settlement
actually and reasonably incurred by him or her in connection with the defense
of any proceeding in which he or she was or is a party or is threatened to be
made a party by reason of being or having been a director of an officer of the
Corporation or by reason of the fact that he or she is or was serving at the
request of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise.  Such right
of indemnification is not exclusive of any other rights to which such director
or officer may be entitled under any now of thereafter existing statute, any
other provision of these Articles, bylaws, agreement, vote of shareholders or
otherwise.  Any repeal or modification of this Article VIII by the shareholders
of the Corporation shall not adversely affect any right or protection of a
director or officer of the Corporation existing at the time of such repeal or
modification.
