                                      ARTICLE II

                                     SHAREHOLDERS

    SECTION 1.  ANNUAL MEETING; TRANSACTION OF BUSINESS, NOMINATION OF
DIRECTORS.  The annual meeting of the shareholders shall be held in the month of
April in each year on such date and at such time as the Board of Directors shall
provide.  The meeting shall be held for the purpose of electing Directors and
for the transaction of such other business as is properly brought before the
meeting in accordance with these By-Laws.  If the election of Directors shall
not be held on the day designated for any annual meeting, or at any adjournment
thereof, the Board of Directors shall cause the election to be held at a meeting
of the shareholders as soon thereafter as conveniently may be.

    To be properly brought before the meeting, business must be either (a)
specified in the notice of meeting (or any supplement thereto) given by or at
the direction of the Board of Directors, (b) otherwise properly brought before
the meeting by or at the direction of the Board of Directors or (c) otherwise
properly brought before the meeting by a shareholder.  In addition to any other
applicable requirements, for business to be properly brought before an annual
meeting by a shareholder, the shareholder must have given timely notice thereof
in writing to the Secretary.  To be timely, a shareholder's notice must be
delivered to or mailed and received at the principal office of the Corporation,
not earlier than October 1 nor later than February 15 immediately prior to the
date of the meeting; PROVIDED, HOWEVER, that in the event that the date of such
meeting is not in the month of April and less than sixty-five days' notice or
prior public disclosure of the date of the meeting is given or made to
shareholders, notice by the shareholder to be timely must be so received not
later than the close of business on the fifteenth day following the day on which
such notice of the date of the annual meeting was mailed or such public
disclosure was made, whichever first occurs.  A shareholder's notice to the
Secretary shall set forth as to each matter the shareholder proposes to bring
before the annual meeting (i) a brief description of the business desired to be
brought before the annual meeting and the reasons for conducting such business
at the annual meeting, (ii) the name and record address of the shareholder
proposing such business, (iii) the class and number of shares of the Corporation
which are beneficially owned by the shareholder and (iv) any material interest
of the shareholder in such business.

    Notwithstanding anything in these By-Laws to the contrary, no business
shall be conducted at the annual meeting except in accordance with the
procedures set forth in this Section



BY-LAWS                                                                 Page 2

1, PROVIDED, HOWEVER, that nothing in this Section 1 shall be deemed to 
preclude discussion by any shareholder of any business properly brought 
before the annual meeting.

    The Chairman of an annual meeting shall, if the facts warrant, determine
and declare to the meeting that business was not properly brought before the
meeting in accordance with the provisions of this Section 1, and if he should so
determine, he shall so declare to the meeting and such business not properly
brought before the meeting shall not be transacted.

    Only persons who are nominated in accordance with the following procedures
shall be eligible for election as directors.  Nominations of persons for
election to the Board of Directors of the Corporation at the annual meeting may
be made at such annual meeting of shareholders by or at the direction of the
Board of Directors, by any nominating committee or person appointed by the Board
of Directors, or by any shareholder of the Corporation entitled to vote for the
election of directors at such meeting who complies with the notice procedures
set forth in this Section 1.  Such nominations, other than those made by or at
the direction of the Board of Directors or by a committee or person appointed by
the Board of Directors, shall be made pursuant to timely notice in writing to
the Secretary.  To be timely, a shareholder's notice shall be delivered to or
mailed and received at the principal office of the Corporation not earlier than
October 1 nor later than February 15 immediately prior to that date of the
meeting; PROVIDED, HOWEVER, that in the event that the date of such meeting is
not in the month of April and less than sixty-five days' notice or prior public
disclosure of the date of the meeting is given or made to shareholders, notice
by the shareholder to be timely must be so received not later than the close of
business on the fifteenth day following the day on which such notice of the date
of the meeting was mailed or such public disclosure was made, whichever first
occurs.  Such shareholder's notice to the Secretary shall set forth:  (a) as to
each person whom the shareholder proposes to nominate for election or
re-election as a director, (i) the name, age, business address and residence
address of the person, (ii) the principal occupation or employment of the
person, (iii) the class and number of shares of capital stock of the Corporation
which are beneficially owned by the person and (iv) any other information
relating to the person that is required to be disclosed in solicitations for
proxies for election of directors pursuant to Regulation 14A under the
Securities Exchange Act of 1934, as amended; and (b) as to the shareholder
giving the notice, (i) the name and record address of such shareholder and (ii)
the class and number of shares of the Corporation which are beneficially owned
by such shareholder.  The Corporation may require any proposed nominee to
furnish such other information as may reasonably be required by the Corporation
to determine the eligibility of such proposed nominee to serve as director of
the Corporation.  No person shall be eligible for election as a director of the
Corporation unless nominated in accordance with the procedures set forth herein.


    The Chairman of the meeting shall, if the facts warrant, determine and
declare to the meeting that a nomination was not made in accordance with the
foregoing procedure, and if he should so determine, he shall so declare to the
meeting and the defective nomination shall be disregarded.

    SECTION 2.  SPECIAL MEETINGS.  Special meetings of the shareholders may be
called by the Chairman of the Board, the President, the Board of Directors or by
the holders of not less than one-fifth of all the outstanding shares entitled to
vote on the matter for which the meeting is called.

    SECTION 3.  PLACE OF MEETING.  The Board of Directors may designate any
place, either within or without the State of Illinois, as the place of meeting
for any annual meeting or for any special meeting called by the Board of
Directors.  If no designation is made, or if a special



BY-LAWS                                                                 Page 3

meeting be otherwise called, the place of meeting shall be the principal 
office of the Corporation in the State of Illinois.

    SECTION 4.  NOTICE OF MEETINGS.  Written notice stating the place, day and
hour of the meeting and, in the case of a special meeting, the purpose or
purposes for which the meeting is called, shall be delivered not less than ten
nor more than sixty days before the date of the meeting, or in the case of a
merger, consolidation, share exchange, dissolution or sale, lease or exchange of
assets not less than twenty nor more than sixty days before the meeting, either
personally or by mail, by or at the direction of the Chairman of the Board, the
President, or the Secretary or the persons calling the meeting, to each
shareholder of record entitled to vote at such meeting.  If mailed, such notice
shall be deemed to be delivered when deposited in the United States mail,
addressed to the shareholder at his or her address as it appears on the records
of the Corporation, with postage thereon prepaid.

    SECTION 5.  FIXING RECORD DATE.  For the purpose of determining
shareholders entitled to notice of or to vote at any meeting of shareholders, or
shareholders entitled to receive payment of any dividend, or in order to make a
determination of shareholders for any other proper purpose, the Board of
Directors of the Corporation may fix in advance a date as the record date for
any such determination of shareholders, such date in any case to be not more
than sixty days and, for a meeting of shareholders, not less than ten days, or
in the case of a merger, consolidation, share exchange, dissolution or sale,
lease or exchange of assets not less than twenty days, immediately preceding
such meeting.

     SECTION 6.  VOTING LISTS.  The Secretary shall make, or cause to have
made, within twenty days after the record date for a meeting of shareholders or
ten days before such meeting, whichever is earlier, a complete list of the
shareholders entitled to vote at such meeting, arranged in alphabetical order,
with the address of and the number of shares held by each, which list, for a
period of ten days prior to such meeting, shall be kept on file at the
registered office of the Corporation and shall be subject to inspection by any
shareholder and to copying at the shareholder's expense, at any time during
usual business hours.  Such list shall also be produced and kept open at the
time and place of the meeting and shall be subject to the inspection of any
shareholder during the whole time of the meeting.  The original share ledger or
transfer book, or a duplicate thereof kept in this State, shall be prima facie
evidence as to who are the shareholders entitled to examine such list or share
ledger or transfer book or to vote at any meeting of shareholders.

    SECTION 7.  QUORUM.  A majority of the outstanding shares of the
Corporation entitled to vote on a matter, represented in person or by proxy,
shall constitute a quorum for consideration of such matter at a meeting of
shareholders.  If a quorum is present, the affirmative vote of the majority of
the shares represented at the meeting and entited to vote on a matter shall be
the act of the shareholders, unless the vote of a greater number or voting by
classes is required by The Business Corporation Act of 1983 or the Articles of
Incorporation, as in effect on the date of such determination.  If a quorum is
not present, a majority of the shares of the Corporation entitled to vote on a
matter and represented in person or by proxy at such meeting may adjourn the
meeting from time to time without further notice.

    SECTION 8.  PROXIES.  A shareholder may appoint a proxy to vote or
otherwise act for the shareholder by signing an appropriate form and delivering
it to the person so appointed; provided, however, no shareholder may name more
than three persons as proxies to attend and to vote the shareholder's shares at
any meeting of shareholders.  No proxy shall be valid after the expiration of
eleven months from the date thereof unless otherwise provided in the proxy. 
Each proxy continues in full force and effect until revoked by the person
executing it prior to the vote



BY-LAWS                                                                 Page 4

pursuant thereto, except as otherwise provided by law.  Such revocation may 
be effected by a writing delivered to the Secretary of the Corporation 
stating that the proxy is revoked or by a subsequent proxy executed by, or by 
attendance at the meeting and voting in person by, the person executing the 
proxy.  The dates contained on the forms of proxy presumptively determine the 
order of execution, regardless of the postmark dates on the envelopes in 
which they were mailed.

    SECTION 9.  VOTING OF SHARES.  Each outstanding share, regardless of class,
shall be entitled to one vote in each matter submitted to a vote at a meeting of
shareholders and, in all elections for Directors, every shareholder shall have
the right to vote the number of shares owned by such shareholder for as many
persons as there are Directors to be elected, or to cumulate such votes and give
one candidate as many votes as shall equal the number of Directors multiplied by
the number of such shares or to distribute such cumulative votes in any
proportion among any number of candidates; provided that, vacancies on the Board
of Directors may be filled as provided in Section 9, Article III of these
By-Laws.  A shareholder may vote either in person or by proxy.

    SECTION 10.  VOTING OF SHARES BY CERTAIN HOLDERS.  Shares of this
Corporation held by the Corporation in a fiduciary capacity may be voted and
shall be counted in determining the total number of outstanding shares entitled
to vote at any given time.

    Shares registered in the name of another corporation, domestic or foreign,
may be voted by any officer, agent, proxy or other legal representative
authorized to vote such shares under the law of incorporation of such
corporation.

    Shares registered in the name of a deceased person, a minor ward or a
person under legal disability may be voted by his or her administrator,
executor, or court appointed guardian, either in person or by proxy without a
transfer of such shares into the name of such administrator, executor, or court
appointed guardian.  Shares registered in the name of a trustee may be voted by
him or her, either in person or by proxy.

    Shares registered in the name of a receiver may be voted by such receiver,
and shares held by or under the control of a receiver may be voted by such
receiver without the transfer thereof into his or her name if authority so to do
is contained in an appropriate order of the court by which such receiver was
appointed.

    A shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledgee, and
thereafter the pledgee shall be entitled to vote the shares so transferred.

    SECTION 11.  VOTING BY BALLOT.  Voting on any question or in any election
may be viva voce unless the presiding officer shall order that voting be by
ballot.

    SECTION 12.  INSPECTORS OF ELECTION.  The Board of Directors in advance of
any meeting of shareholders may appoint inspectors to act at such meeting or any
adjournment thereof.  If inspectors of election are not so appointed, the
officer or person acting as chairman at any such meeting may, and on the request
of any shareholder or his proxy, shall make such appointment.  In case any
person appointed as inspector shall fail to appear or to act, the vacancy may be
filled by appointment made by the Board of Directors in advance of the meeting
or at the meeting by the officer or person acting as chairman.

    Such inspectors shall ascertain and report the number of shares represented
at the meeting, based upon their determination of the validity and effect of
proxies; count all votes and



BY-LAWS                                                                 Page 5

report the results; and do such other acts as are proper to conduct the 
election and voting with impartiality and fairness to all the shareholders.

    Each report of an inspector shall be in writing and signed by him or her or
by a majority of them if there be more than one inspector acting at such
meeting.  If there is more than one inspector, the report of a majority shall be
the report of the inspectors.  The report of the inspector or inspectors on the
number of shares represented at the meeting and the results of the voting shall
be prima facie evidence thereof.


                                     ARTICLE III

                                      DIRECTORS

be residents of Illinois or shareholders of the Corporation.

    SECTION 3.  REGULAR MEETINGS.  A regular annual meeting of the Board of
Directors shall be held without other notice than this By-Law, immediately
after, and at the same place as, the annual meeting of shareholders.  Other
regular meetings of the Board of Directors shall be held at the principal office
of the Corporation on the second Friday of every month at 9:00 a.m. without
other notice than this By-Law.  The Board of Directors may provide, by
resolution, for the holding of the regular monthly meetings at a different time
and place, either within or without the State of Illinois, or for the omission
of the regular monthly meeting altogether.  Where the Board of Directors has, by
resolution, changed or omitted regular meetings, no other notice than such
resolution shall be given.

    SECTION 4.  SPECIAL MEETINGS.  Special meetings of the Board of Directors
may be called by or at the request of the Chairman of the Board, the Chairman of
the Executive Committee, the President, or of any four Directors.  The persons
authorized to call special meetings of the Board of Directors may fix any place,
either within or without the State of Illinois, as the place for holding any
special meeting of the Board of Directors.

    SECTION 5.  NOTICE.  Notice of any special meeting shall be given: (i) at
least one day prior thereto if the notice is given personally or by an
electronic transmission, (ii) at least two business days prior thereto if the
notice is given by having it delivered by a third party entity that provides
delivery services in the ordinary course of business and guarantees delivery of
the notice to the Director no later than the following business day, and (iii)
at least seven days prior thereto if the notice is given by mail.  For this
purpose, the term "electronic transmission" may include, but shall not be
limited to, a telex, facsimile, or other electronic means.  Notice shall be
delivered to the Director's business address and/or telephone number and shall
be deemed given upon electronic transmission, upon delivery to the third party
delivery service, or upon being deposited in the United States mail with postage
thereon prepaid.  Any Director may waive notice of any meeting by signing a
written waiver of notice either before or after the meeting.  Attendance of a
Director at any meeting shall constitute a waiver of notice of such meeting,
except where a Director attends a meeting for the



BY-LAWS                                                                 Page 6

express purpose of objecting to the transaction of any business because the 
meeting is not lawfully called or convened.  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.

    SECTION 6.  QUORUM.  A majority of the number of Directors fixed by these
By-Laws shall constitute a quorum for transaction of business at any meeting of
the Board of Directors; provided, that if less than a majority of such number of
Directors are present at said meeting, a majority of the Directors present may
adjourn the meeting from time to time without further notice.

    SECTION 7.  MANNER OF VOTING.  The act of the majority of the Directors
present at a meeting at which a quorum is present shall be the act of the Board
of Directors.

    SECTION 8.  INFORMAL ACTION BY DIRECTORS.  Any action required to be taken
at a meeting of the Board of Directors, or any other action which may be taken
at a meeting of the Board of Directors or a committee thereof, may be taken
without a meeting if a consent in writing, setting forth the action so taken,
shall be signed by all of the Directors entitled to vote with respect to the
subject matter thereof, or by all the members of such committee, as the case may
be.

    The consent shall be evidenced by one or more written approvals, each of
which sets forth the action taken and bears the signature of one or more
Directors.  All the approvals evidencing the consent shall be delivered to the
Secretary of the Corporation to be filed in the corporate records.  The action
taken shall be effective when all the Directors have approved the consent unless
the consent specifies a different effective date.

    Any such consent signed by all the Directors or all the members of a
committee shall have the same effect as a unanimous vote.

    SECTION 9.  VACANCIES.  Any vacancy occurring in the Board of Directors and
any directorship to be filled by reason of an increase in the number of
Directors, may be filled by election at an annual meeting or at a special
meeting of shareholders called for that purpose.  A Director elected to fill a
vacancy shall serve until the next annual meeting of shareholders.  A majority
of Directors then in office may also fill one or more vacancies arising between
meetings of shareholders by reason of an increase in the number of Directors or
otherwise, and any Director so selected shall serve until the next annual
meeting of shareholders, provided that at no time may the number of Directors
selected to fill vacancies in this manner during any interim period between
meetings of shareholders exceed 33-1/3 per cent of the total membership of the
Board of Directors.

    SECTION 10.  PRESUMPTION OF ASSENT.  A Director of the Corporation who is
present at a meeting of the Board of Directors or any committee thereof at which
action on any corporate matter is taken is conclusively presumed to have
assented to the action taken unless his or her dissent is entered in the minutes
of the meeting or unless he or she files his or her written dissent to such
action with the person acting as the secretary of the meeting before the
adjournment thereof or forwards such dissent by registered or certified 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.

    SECTION 11.  APPOINTMENT OF AUDITORS.  Upon the recommendation of the Audit
Committee, the Board of Directors shall appoint annually a firm of independent
public accountants as auditors of the Corporation.  Such appointment shall be
submitted to the shareholders

for ratification at the Annual Meeting next following such appointment.  
Should the holders of a majority of the shares represented at the meeting 
fail to ratify the appointment of any firm as auditors of the Corporation, or 
should the Board of Directors for any reason determine that such appointment 
be terminated, the Board of Directors shall appoint another firm of 
independent public accountants to act as auditors of the Corporation and such 
appointment shall be submitted to the shareholders for ratification at the 
Annual or Special Shareholders Meeting next following such appointment.

                                      ARTICLE IV

Corporation is organized under the laws of the State of Illinois; the name of
the person to whom issued; the number and class of shares; and the designation
of the series, if any, which such certificate represents.  Each certificate
shall be consecutively numbered or otherwise identified.  The name of the person
to whom the shares represented thereby are issued, with the number of shares and
date of issue, shall be entered on the books of the Corporation.  All
certificates surrendered to the Corporation for transfer shall be canceled, and

for a like number of shares shall have been surrendered and canceled, except in
the case of lost, destroyed or mutilated certificates.

time to time appoint such Transfer Agents and Registrars in such locations as it

    loss, destruction or mutilation so far as known to him or her and further

              certificate or certificates,


    upon receipt of a bond, with one or more sureties, in the amount to be
    determined by the party giving such approval; or

    (b)  that issuance of the said duplicate certificate or certificates is
    approved by the Board of Directors upon such terms and conditions as it
