performed by the officer given the authority to act for such absent or
non-acting officer under these by-laws or by some person appointed by the
meeting.

appointed, the chairman of the meeting may, appoint one or more inspectors. Each
inspector, before entering upon the discharge of his duties, shall take and sign
an oath faithfully to execute the duties of inspector at such meeting with
strict impartiality and according to the best of his ability. The inspectors

and questions arising in connection with the right to vote, count and tabulate
all votes, ballots, or consents, determine the results, and do such acts as are

the office of director shall act as an inspector of an election of directors.

                            ARTICLE THREE: DIRECTORS

     3.1. Management. The business and property of the Corporation shall be
managed by the board of directors. Subject to the restrictions imposed by law,
the certificate of incorporation of the Corporation, or these by-laws, the board
of directors may exercise all the powers of the Corporation.

     3.2 Number; Qualification; Election; Term. The number of directors which
shall constitute the entire board of directors shall be not less than one. The
first board of directors shall consist of the number of directors named in the
certificate of incorporation of the Corporation or, if no directors are so
named, shall consist of the number of directors elected by the incorporators at
an organizational meeting or by unanimous written consent in lieu thereof.
Thereafter, within the limits above specified, the number of directors which
shall constitute the entire board of directors shall be determined by resolution
of the board of directors or by resolution of the stockholders at the annual
meeting thereof or at a special meeting thereof called for that purpose. Except
as otherwise required by law, the certificate of incorporation of the
Corporation, or these bylaws, the directors shall be elected at an annual
meeting of stockholders at which a quorum is present. Directors shall be elected
by a plurality of the votes of the shares present in person or represented by
proxy and entitled to vote on the election of directors. Each director so chosen
shall hold office until the first annual meeting of stockholders held after his
election and until his successor is elected and qualified or, if earlier, until
his death, resignation, or removal from office. None of the directors need be a
stockholder of the Corporation or a resident of the State of Michigan. Each
director must have attained the age of majority.

     3.3 Change in Number. No decrease in the number of directors constituting
the entire board of directors shall have the effect of shortening the term of
any incumbent director.

     3.4. Removal. Except as otherwise provided in the certificate of
incorporation of the Corporation or these by-laws, at any meeting of
stockholders called expressly for that purpose, any director or the entire board
of directors may be removed, with or without cause, by a vote of the holders of
a majority of


                                       7
<PAGE>

the shares then entitled to vote on the election of directors; provided,
however, that so long as stockholders have the right to cumulate votes in the
election of directors pursuant to the certificate of incorporation of the
Corporation, if less than the entire board of directors is to be removed, no one
of the directors may be removed if the votes cast against his removal would be
sufficient to elect him if then cumulatively voted at an election of the entire
board of directors.

     3.5. Vacancies. Vacancies and newly-created directorships resulting from
any increase in the authorized number of directors may be filled by a majority
of the directors then in office, though less than a quorum, or by the sole
remaining director, and each director so chosen shall hold office until the
first annual meeting of stockholders held after his election and until his
successor is elected and qualified or, if earlier, until his death, resignation,
or removal from office. If there are no directors in office, an election of
directors may be held in the manner provided by statute. If, at the time of
filling any vacancy or any newly-created directorship, the directors then in
office shall constitute less than a majority of the whole board of directors (as
constituted immediately prior to any such increase), the Court of Chancery may,
upon application of any stockholder or stockholders holding at least 10% of the
total number of the shares at the time outstanding having the right to vote for
such directors, summarily order an election to be held to fill any such
vacancies or newly-created directorships or to replace the directors chosen by
the directors then in office. Except as otherwise provided in these by-laws,
when one or more directors shall resign from the board of directors, effective
at a future date, a majority of the directors then in office, including those
who have so resigned, shall have the power to fill such vacancy or vacancies,
the vote thereon to take effect when such resignation or resignations shall
become effective, and each director so chosen shall hold office as provided in
these by-laws with respect to the filling of other vacancies.

     3.6. Meetings of Directors. The directors may hold their meetings and may
have an off ice and keep the books of the corporation, except as otherwise
provided by statute, in such place or places within or without the State of
Michigan as the board of directors may from time to time determine or as shall
be specified in the notice of such meeting or duly executed waiver


                                       8
<PAGE>

of notice of such meeting.

     3.7. First Meeting. Each newly elected board of directors may hold its
first meeting for the purpose of organization and the transaction of business,
if a quorum is present, immediately after and at the same place as the annual
meeting of stockholders, and no notice of such meeting shall be necessary.

     3.8. Election of officers. At the first meeting of the board of directors
after each annual meeting of stockholders at which a quorum shall be present,
the board of directors shall elect the officers of the Corporation.

     3.9. Regular Meetings. Regular meetings of the board of directors shall be
held at such times and places as shall be designated from time to time by

held whenever called by the Chairman of the Board, the President, or any
director.

     3.11 Notice. The Secretary shall give notice of each special meeting to
each director at least 24 hours before the meeting. Notice of any such meeting
need not be given to any director who shall, either before or after the meeting,
submit a signed waiver of notice or who shall attend such meeting without
protesting, prior to or at its commencement, the lack of notice to him. Neither
the business to be transacted at, nor the purpose of, any regular or special
meeting of the board of directors need be specified in the notice or waiver of
notice of such meeting.

     3.12. Quorum; Majority Vote. At all meetings of the board of directors, a
majority of the directors fixed in the manner provided in these by-laws shall
constitute a quorum for the transaction of business. If at any meeting of the
board of directors there be less than a quorum present, a majority of those
present or any director solely present may adjourn the meeting from time to time
without further notice. Unless the act of a greater number is required by law,
the certificate of incorporation of the Corporation, or these by-laws, the act
of a


                                       9
<PAGE>

majority of the directors present at a meeting at which a quorum is in
attendance shall be the act of the board of directors. At any time that the
certificate of incorporation of the Corporation provides that directors elected
by the holders of a class or series of stock shall have more or less than one
vote per director on any matter, every reference in these by-laws to a majority
or other proportion of directors shall refer to a majority or other proportion
of the votes of such directors.

     3.13. Procedure. At meetings of the board of directors, business shall be
transacted in such order as from time to time the board of directors may
determine. The Chairman of the Board, if such office has been filled, and, if
not or if the Chairman of the Board is absent or otherwise unable to act, the
President shall preside at all meetings of the board of directors. In the
absence or inability to act of either such officer, a chairman shall be chosen
by the board of directors from among the directors present. The Secretary of the
Corporation shall act as the secretary of each meeting of the board of directors
unless the board of directors appoints another person to act as secretary of the
meeting. The board of directors shall keep regular minutes of its proceedings
which shall be placed in the minute book of the Corporation.

     3.14. Presumption of Assent. A director of the Corporation who is present
at the meeting of the board of directors at which action on any corporate matter
is taken shall be presumed to have assented to the action unless his dissent
shall be entered in the minutes of the meeting or unless he shall file his
written dissent to such action with the person acting as secretary of the
meeting before the adjournment thereof or shall forward any dissent by certified
or registered mail to the Secretary of the Corporation immediately after the
adjournment of the meeting. Such right to dissent shall not apply to a director
who voted in favor of such action.

     3.15 Compensation. The board of directors shall have the authority to fix
the compensation, including fees and reimbursement of expenses, paid to
directors for attendance at regular or special meetings of the board of
directors or any committee thereof; provided, that nothing contained herein
shall be construed to preclude any director from serving the Corporation in any
other capacity or receiving compensation


                                       10

time to fill vacancies in, to change the membership of, and to discharge any

greater number is required by law, the certificate of incorporation of the
Corporation, or these by-laws.

directors may be removed by the board of directors whenever in its judgment the
