         Section 7. Redemption of Control Shares. Consistent with the provisions
of Section 799 of the Michigan Business Corporation Act, MCL 450.1799, control
shares of the Company acquired in a control share acquisition, with respect to

time during the period ending 60 days after the last acquisition of control
shares or the power to direct the exercise of voting power of control shares by
the acquiring person, subject to redemption by the Company at the fair value of
the shares pursuant to procedures adopted by the Board of Directors.

         After an acquiring person statement has been filed and after the
meeting at which the voting rights of the control shares acquired in a control
share acquisition are submitted to the shareholders, the shares are subject to
redemption by the Company at the fair value of the shares pursuant to procedures
adopted by the Board of Directors unless the shares are accorded full voting
rights by the shareholders as provided in Section 798 of the Michigan Business
Corporation Act.

                                   ARTICLE II

                             SHAREHOLDERS' MEETINGS

         Section 1. Time, Place and Purpose. Meetings of the shareholders of the
Corporation shall be held annually on such date at such time and place as shall
be determined by the Board of Directors for the purpose of electing Directors
and for the transaction of such other business as may properly be brought before
the meeting.

         Section 2. Special Meetings. Special meetings of the shareholders may
be called by the President and Secretary, and shall be called by either of them
by vote of a majority of the Board of Directors or at the request in writing of
shareholders of record owning a majority of the entire shares of the Corporation
issued and outstanding and entitled to vote at such meetings.

         Section 3. Notice. Written notice of any shareholders' meeting shall be
mailed to each shareholder of record entitled to vote at the meeting at his last
known address, as the same appears on the stock book of the Corporation, or
otherwise, or delivered in person, not less than ten (10) nor more than sixty
(60) days before any meeting, and such notice of meeting shall indicate the
object or objects thereof. Nevertheless, if all the shareholders entitled to
vote at the meeting shall waive notice of the meeting, no notice of the same
shall be required and, whenever all the shareholders entitled to vote at the
meeting shall meet in person or by proxy, such meeting shall be valid for all
purposes, without call or notice, and at such meeting any corporate action shall
not be invalid for want of notice.

         Section 4. Quorum. At any meeting of the shareholders, the holders of
the issued and outstanding shares of the Corporation entitled to cast a majority
of the votes at the meeting, whether present in person or represented by proxy,
shall constitute a quorum. The shareholders present in person or by proxy at
such meeting may continue to do business until adjournment, notwithstanding the
withdrawal of enough shareholders to leave less than a quorum. Whether or

                                      -2-


not a quorum is present, meetings may be adjourned from time to time to a
further date without further notice other than the announcement at such meeting
and, when a quorum shall be present upon such adjourned date, any business may
be transacted which might have been transacted at the meeting as originally
called.

         Section 5. Voting. Each shareholder entitled to vote at any meeting
shall have one vote in person or by proxy for each share held by him which has
voting power upon the matter in question at the time, but no proxy shall be
voted after three years from its date unless said proxy provides for a longer
period. In all elections for Directors, each shareholder entitled to vote shall
have the right to vote, in person or by proxy, the number of voting shares owned
by him, for as many persons as there are Directors to be elected, or to cumulate
said shares and give one candidate as many votes as the number of Directors
multiplied by the number of his voting shares shall equal, or to distribute them
on the same principle among as many candidates as he shall see fit.

         Section 6. Organization. Meetings of the shareholders shall be presided
over by the Chairman of the Board, or the President, or if neither is present,
by any Vice President or, if no Vice President is present, by a chairman to be
chosen at the meeting. The Secretary of the Corporation or, if he is not
present, an Assistant Secretary of the Corporation, if present, shall act as
Secretary of the meeting, but if no such officer is present, the presiding
officer shall appoint any person to act as Secretary of the meeting.

         Section 7. Inspectors. The Board of Directors, in advance of a
shareholders' meeting, may appoint one or more inspectors to act at the meeting
or any adjournment thereof. The inspectors shall perform such duties and shall
make such determinations as are prescribed by law.

         Section 8. Giving Notice. Any notice required by statute or by these
Bylaws to be given to the shareholders, or to Directors, or to any officer of
the Corporation, shall be deemed to be sufficient to be given by depositing the
same in a post office box in a sealed, postpaid wrapper, addressed to such
shareholder, Director, or officer at his last known address with proper postage
and such notice shall be deemed to have been given at the time of such mailing.

         Section 9. New Shareholders. Every person becoming a shareholder in
this Corporation shall be deemed to assent to these Bylaws, and shall designate
to the Secretary the address to which he desires that the notice herein required
to be given may be sent, and all notices mailed to such addresses, with postage
prepaid, shall be considered as duly given at the date of mailing, and any
person failing to so designate his address shall be deemed to have waived notice
of such meeting.

Directors may, from time to time, determine.

         Section 3. Meetings. Meetings of the Board of Directors may be called
at any time by the Chairman, President or Secretary, or by a majority of the
Board of Directors. Directors shall be notified in writing of the time, place
and purpose of all meetings of the Board at least three days prior thereto. Any
Director shall, however, be deemed to have waived such notice by his attendance
at any meeting. The Chairman of the Board, or in his absence the President,
shall preside at meetings of the Board.

         Section 4. Quorum. A majority of the Board of Directors shall
constitute a quorum for the transaction of business and, if at any meeting of
the Board of Directors there be less than a quorum present, a majority of those
present may adjourn the meeting from time to time.

compensation for his services as Director, unless otherwise especially ordered
by the Board of Directors or by the Bylaws.

         Section 7. Age of Retirement. Notwithstanding anything above to the
contrary, no individual shall serve as a director past the Retirement Age. Any
individual reaching the Retirement Age while serving as director shall be
considered to have resigned as of that date. No individual who has reached the
Retirement Age shall qualify to run for election, or serve, as a director. The
Retirement Age for individuals serving as directors on January 1, 1987 shall be

Board of Directors, however, may waive the provisions of this Section as to any
director in its discretion by majority vote of the remaining directors in

above to the contrary, any individual who is an employee of the Corporation or

considered to have resigned as a director as of that date. The Board

                                      -4-


of Directors, however, may waive the provisions of this Section as to any
director in its discretion by majority vote of the remaining directors in
office.

         Section 9. Qualifications. In addition to any other qualifications for
a director imposed by law, these Bylaws, or the Articles of Incorporation, a
person shall not qualify to serve as a director if that person has previously
served concurrently as a director of the Corporation and an employee of the
Corporation or any majority-owned subsidiary, but is no longer an employee. The
Board of Directors, however, may waive the provisions of this Section as to any
director in its discretion by majority vote of the remaining directors in
office.

         Section 10. Chairman of the Board. A Chairman of the Board of Directors
shall be elected annually. The Chairman of the Board shall preside at all
meetings of the shareholders and of the Board of Directors; and the Chairman
shall have such other powers and duties as designated in these bylaws and as
from time to time may be assigned to him by the Board of Directors.

         Section 11. Lead Director. So long as the position of the Chairman of
the Board is not deemed Independent by the Board, there may be a Lead Director
who shall be an Independent Director of the Company selected by the Independent
Directors to serve a three-year term commencing the day following the annual
meeting. "Independence of a Director" requires the Board's affirmative
determination consistent with the tests prescribed by Section 303A.02 of the
NYSE Listed Company Manual. No Lead Director shall serve consecutive terms. The
duties of the Lead Director shall be to convene and chair meetings of the
Independent Directors and to assume other responsibilities which the Independent
Directors might designate from time to time.

Board of Directors at their regular annual meeting or at any other meeting. The
term of office shall be for one year and until their successors are chosen. Any
two or more of the offices, except those of President and Vice President, may be
held by the same person, but no officer shall execute, acknowledge, or verify
any instrument in more than one capacity. The Board of Directors shall fix the
salaries of the officers of the Corporation. The Board of Directors may also
fill any vacancy in the foregoing offices at any regular or special meeting duly
called and held.

         Section 2. Appointments and Removal of Officers. The Board of Directors
may also appoint such other officers and agents as they may deem necessary for
the transaction of the business of the Corporation. All officers and agents

perform such duties in the management of the property and affairs of the
Corporation as may be designated by the Board of Directors. Without limitation
of any right of an officer or agent to recover damages for breach of contract,

judgment, the business interests of the Corporation will be served thereby.

         Section 3. Bonding of Officers. The Board of Directors may secure the
fidelity of any or all of such officers by bond or otherwise.
