                                     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 the first business day of January
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





BY-LAWS                                                               Page 2



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 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 the first business day of January 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 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






BY-LAWS                                                               Page 3



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 Chief Executive Officer, 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 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 cases 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
Chief Executive Officer, 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







BY-LAWS                                                               Page 4



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 entitled 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 delivering a valid appointment to the
person so appointed or such person's agent; 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.  Without limiting the
manner in which a shareholder may appoint such a proxy pursuant to these
By-Laws, the following shall constitute valid means by which a shareholder may
make such an appointment:

     (a)  A shareholder may sign a proxy appointment form.  The shareholder's
          signature may be affixed by any reasonable means, including, but not
          limited to, by facsimile signature.

     (b)  A shareholder may transmit or authorize the transmission of a
          telegram, cablegram, or  other means of electronic transmission;
          provided that any such transmission must either set forth or be
          submitted with information from which it can be determined that the
          telegram, cablegram, or other electronic transmission was authorized
          by the shareholder.  If it is determined that the telegram, cablegram,
          or other electronic transmission is valid, the inspectors or, if there
          are no inspectors, such other persons making that determination shall
          specify the information upon which they relied.

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 appointing the proxy prior to
the vote 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 delivery of
a valid proxy by, or










BY-LAWS                                                               Page 5



by the attendance at the meeting and voting in person by the person
appointing the proxy.  The dates of the proxy shall presumptively determine
the order of appointment.

     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






BY-LAWS                                                               Page 6



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 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

     SECTION 1.  GENERAL POWERS.  The business and affairs of the Corporation
shall be managed under the direction of the Board of Directors.

     SECTION 2.  NUMBER, TENURE AND QUALIFICATIONS.  The number of Directors of
the Corporation shall be thirteen.  The terms of all Directors shall expire at
the next annual meeting of shareholders following their election.  Despite the
expiration of a Director's term, he or she shall continue to serve until the
next meeting of shareholders at which Directors are elected.  Directors need not
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 Chief Executive Officer, 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.







BY-LAWS                                                               Page 7



     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 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 to 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





BY-LAWS                                                               Page 8



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

one or more committees and appoint members of the Board to serve on the
committee or committees.  Each committee shall have three or more members, who

each committee to be chairman of the committee.  The Board shall designate a
secretary of each committee who may be, but need not be, a member of the
committee or the Board.

     SECTION 2.  COMMITTEE MEETINGS.  A majority of any committee shall
constitute a quorum and a majority of the committee is necessary for
committee action.  A committee may act by unanimous consent in writing
without a meeting. Committee meetings may be called by the Chairman of the
Board, the chairman of the committee, or any two of the committee's





BY-LAWS                                                               Page 9

notice of such meeting.  Notice of each committee meeting shall be given to
each committee member.  Each Committee shall keep minutes of its proceedings
and such minutes shall be distributed to the Board of Directors.

Committee.  A majority of the members of the Committee shall be selected from
those Directors who are not then serving as full-time employees of the
Corporation or any of its subsidiaries.

may, when the Board of Directors is not in session, exercise the authority of
the Board in the management of the business and affairs of the Corporation;
provided, however, the Committee may not:

          (1)  authorize distributions;

          (2)  approve or recommend to shareholders any act the Business

               a general formula or method prescribed by the Board;

          (8)  authorize or approve the issuance or sale, or contract for sale,
               of shares or determine the designation and relative rights,
               preferences, and limitations of a series of shares, except that
               the Board may direct the Committee to fix the specific terms of
               the issuance or sale or contract for sale or the number of shares
               to be allocated to particular employees under an employee benefit
               plan; or

          (9)  amend, alter, repeal, or take action inconsistent with any
               resolution or action of the Board of Directors when the
               resolution or action of the Board of Directors provides by its
               terms that it shall not be amended, altered or repealed by action
               of the Committee.
