      SECTION 2.1. Annual Meeting. The annual meeting of the shareholders shall
be held on the last Thursday of the month of March in each year, if not a legal
holiday, or, if a legal holiday, then on the next preceding business day, for

thereof, the Board of Directors shall cause such election to be held at a
special meeting of the shareholders as soon thereafter as convenient.

      SECTION 2.2. Special Meetings. Except as otherwise prescribed by statute,
special meetings of the shareholders for any purpose or purposes, may be called

<PAGE>

not less than 20% of the total voting power. Such request shall state the
purpose or purposes of the proposed meeting.

      SECTION 2.3. Place of Meetings. Each meeting of the shareholders for the
election of directors shall be held at the principal office of the Company in
the City of Chicago, Illinois, unless the Board of Directors shall by resolution
designate another place as the place of such meeting. Meetings of shareholders
for any other purpose may be held at such place, and at such time as shall be
determined by the Chairman of the Board, the Vice Chairman, or the President, or
in their absence, by the Secretary, and stated in the notice of the meeting or
in a duly executed waiver of notice thereof.

      SECTION 2.4. Notice of Meetings. Written or printed notice stating the
place, date and hour of each annual or special meeting of the shareholders, and,
in the case of a special meeting, the purpose or purposes for which the meeting

otherwise provided by statute or these by-laws. If a quorum shall not be present
or represented at any meeting of the shareholders, the shareholders entitled to
vote thereat, present in person or represented by proxy, shall have power to

which might have been transacted at the meeting as originally noticed.

      SECTION 2.6. Proxies. At every meeting of the shareholders, each
shareholder having the right to vote thereat shall be entitled to vote in person
or by proxy. Such proxy shall be appointed by an instrument in writing

meeting.

      SECTION 2.7. Voting. At each meeting of the shareholders, each shareholder
shall be entitled to one vote for each share of stock entitled to vote thereat
which is registered in the name of such shareholder on the books of the Company.
At all elections of directors of the Company, the holders of shares of stock of
the Company shall be entitled to cumulative voting. When a quorum is present at
any meeting of the shareholders, the vote of the holders of a majority of the

presence of not less than a majority of the total number of directors specified

present at any meeting at which there is a quorum shall be the act of the Board
of Directors, except as may be otherwise specifically provided by statute. If a

announcement at the meeting, until a quorum shall be present. In determining the
presence of a quorum at a meeting of the directors or a committee thereof for
the purpose of authorizing a contract or transaction between the Company and one
or more of its directors, or between the Company and any other corporation,
partnership, association, or other organization in which one or more of the

interest in such other organization, such interested directors may be counted in
determining a quorum.

the Board of Directors shall be the Chairman of the Board or, in his or her
absence, the Vice Chairman or, in his or her absence, the President or, in his

majority of the directors present at the meeting.

      SECTION 3.7. Action Without Meeting. Any action required or permitted to
be taken at any meeting of the Board of Directors, or any committee thereof, may

the case may be, consent thereto in writing and such writing or writings are
filed with the minutes of the proceedings of the Board or such committee.

      SECTION 3.8. Fees and Compensation of Directors. Directors shall not
receive any stated salary for their services as such; but, by resolution of the
Board of Directors, reasonable fees, with or without expenses of attendance, may
be allowed. Members of the Board shall be allowed their reasonable traveling
expenses when actually engaged in the business of the Company, to be audited and
allowed as in other cases of demands against the Company. Members of standing or
special committees may be allowed fees and expenses for attending committee
meetings. Nothing herein contained shall be construed to preclude any director
from serving the Company in any other capacity and receiving compensation
therefor.

      SECTION 6.1. Certificates of Stock. The certificates of stock of the
Company shall be in such form as may be determined by the Board of Directors,

be numbered and shall be entered in the books of the Company as they are issued.
They shall exhibit the holder's name and number of shares and shall be signed by
the Chairman of the Board, the Vice Chairman, the President or a Vice President
and also by the Treasurer or an Assistant Treasurer or the Secretary or an
Assistant Secretary and shall bear the corporate seal or a facsimile thereof. If

officer or employee of the transfer agent or registrar, who has signed or whose
facsimile signature has been placed upon such certificate ceases to be an
officer of the Company, or an officer or employee of the transfer agent or
registrar, before such certificate is issued, said certificate may be issued

employee of the transfer agent or registrar, had not ceased to be such at the
date of issue.

      SECTION 6.2. Transfer of Stock. Upon surrender to the Company of a
certificate for shares duly endorsed or accompanied by proper evidence of
succession, assignment or authority to transfer, and upon payment of applicable
taxes with respect to such transfer, it shall be the duty of the Company,
subject to such rules and regulations as the Board of Directors may from time to

entitled thereto, cancel the old certificate and record the transaction upon its
books.

      SECTION 6.3. Shareholders of Record. The Company shall be entitled to
treat the holder of record of any share or shares of stock as the holder in fact
thereof

                                       13

and, accordingly, shall not be bound to recognize any equitable or other claim
to or interest in such share or shares on the part of any other person, whether
or not it shall have express or other notice thereof, except as otherwise
provided by statute.

      SECTION 6.4. Lost, Destroyed or Stolen Certificates. The Board of
Directors, in individual cases or by general resolution, may direct a new
certificate or certificates to be issued by the Company as a replacement for a
certificate or certificates for a like number of shares alleged to have been
lost, destroyed or stolen, upon the making of an affidavit of that fact by the
person claiming the certificate or certificates of stock to be lost, destroyed
or stolen. When authorizing such issue of a new certificate or certificates, the
Board of Directors may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, destroyed or stolen
certificate or certificates, or his or her legal representative, to give the
Company a bond in such form and amount as it may direct as indemnity against any
claim that may be made against the Company with respect to the certificate or
certificates alleged to have been lost, destroyed or stolen.

signed by two officers of the Company. When prescribed by the Board, bonds,
promissory notes, and other obligations of the Company may bear the facsimile
signature of the officer who is authorized to sign such instruments and,

the holding of such meeting without notice.

      These by-laws may be added to, amended or repealed at any regular or
special meeting of the Board by a vote of a majority of the membership of the
Board.
