                                      OFFICES

     The principal office of the Corporation in the State of Illinois shall 
be located at the intersection of State Routes 43 and 137 in the County of 
Lake. The Corporation may have such other offices either within or without 
the State of Illinois as the business of the Corporation may require from 
time to time.

     The registered office of the Corporation may be, but need not be, 
identical with the principal office in the State of Illinois.  The address of 
the registered office may be changed from time to time by the Board of 
Directors.

                                     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




BY-LAWS                                                              Page 6

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 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

     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 reason of an increase in the number of 
Directors, may be filled by




BY-LAWS                                                              Page 8


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
                                          
                                     COMMITTEES

     SECTION 1.  APPOINTMENT.  A majority of the Board of Directors may 
create 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 serve at the pleasure of the Board.  The Board shall designate 
one member of 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


members.  The time and place of committee meetings shall be designated in the 
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.

     SECTION 3.  EXECUTIVE COMMITTEE.  The Board shall appoint an Executive 
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.

     SECTION 4.  DUTIES OF THE EXECUTIVE COMMITTEE.  The Executive Committee 
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
               Corporation Act of 1983 requires to be approved by shareholders.

          (3)  fill vacancies on the Board or on any of its committees;

          (4)  elect or remove Officers or fix the compensation of any member of
               the Committee;
