such places, within or without the State of Delaware, as may from time 
to time be designated by the board of directors.

     (b)  Annual Meeting.

          (i)  The annual meeting of stockholders shall be held on the 
second Wednesday in April in each year at a time designated by the 
board of directors, or at such a time and date as may be designated 
by the board.


          (ii)  At an annual meeting of the stockholders, only such 
business shall be conducted as shall have been properly brought before 
the meeting.  To be properly brought before an annual meeting, 
business must be (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 stockholder.  For business to be 
properly brought before an annual meeting by a stockholder, the 
stockholder must have given timely notice thereof in writing to the 
secretary of the corporation.  To be timely, a stockholder's notice 
must be delivered to or mailed and received at the principal executive 
offices of the corporation, not less than 45 days nor more than 90 
days prior to the meeting; provided, however, that in the event that 
less than 60 days' notice of the date of the meeting is given or made 
to stockholders, notice by the stockholder to be timely must be so 
received not later than the close of business on the fifteenth (15th) 
day following the date on which such notice of the date of the annual 
meeting was mailed.  A stockholder's notice to the secretary shall 
set forth as to each matter the stockholder proposes to bring before 
the annual meeting (a) a brief description of the business desired 
to be brought before the annual meeting, (b) the name and address, 
as they appear on the corporation's books, of the stockholder proposing 
such business, (c) the class and number of shares of the corporation 
which are beneficially owned by the stockholder and (d) any material 
interest of the stockholder in such business.  Notwithstanding anything 
in the bylaws to the contrary, no business shall be conducted at an 
annual meeting except in accordance with the procedures set forth in 
this Section 1(b)(ii).  The presiding officer of an annual meeting 
shall, if the facts warrant, determine and declare to the meeting 
that business was not properly brought before the meeting and in 
accordance with the provisions of this Section 1, and if he should 
so determine, he shall so declare to the meeting and any such business 
not properly brought before the meeting shall not be transacted.

     (c)  Special Meetings.  Special meetings of the stockholders of 
this corporation for any purpose or purposes may be called at any time 
by the chairman of the board or the vice chairman, or by the board of 
directors pursuant to a resolution approved by a majority of the 
entire board of directors, but such special meetings may not be 
called by any other person or persons.

     (d)  Notice of Meetings.  Notice of every meeting of the 
stockholders shall be given in the manner prescribed by law.

     (e)  Quorum.  Except as otherwise required by law, the certificate 
of incorporation and these bylaws, the holders of not less than 
one-third of the shares entitled to vote at any meeting of the 
stockholders, present in person or by proxy, shall constitute a quorum 
and the act of the majority of such quorum shall be deemed the act 
of the stockholders.  If a quorum shall fail to attend any meeting, 
the chairman of the meeting may adjourn the meeting to another place, 
date or time.  If a notice of any adjourned special meeting of 
stockholders is sent to all stockholders entitled to vote thereat, 
stating that it will be held with those present constituting a 
quorum, then, except as otherwise required by law, those present 
at such adjourned meeting shall constitute a quorum and all matters 
shall be determined by a majority of votes cast at such meeting.


Section 2.  Determination of Stockholders Entitled to Vote.

     To determine the stockholders entitled to notice of any meeting 
or to vote, the board of directors may fix in advance a record date 
as provided in Article VI, Section 1 hereof, or if no record date is 
fixed by the board a record date shall be determined as provided by law.

Section 3.  Voting.

     (a)  Subject to the provisions of applicable law, and except 
as otherwise provided in the certificate of incorporation, each 
stockholder present in person or by proxy shall be entitled to one 
vote for each full share of stock registered in the name of such 
stockholder at the time fixed by the board of directors or by law 
as the record date of the determination of stockholders entitled to 
vote at a meeting.

     (b)  Every stockholder entitled to vote may do so either in person 
or by one or more agents authorized by a written proxy executed by 
the person or his duly authorized agent whether by manual signature, 
typewriting, telegraphic transmission or otherwise.

     (c)  Voting may be by voice or by ballot as the chairman of the 
meeting shall determine.

     (d)  In advance of any meeting of stockholders the board of 
directors may appoint one or more persons (who shall not be candidates 
for office) as inspectors of election to act at the meeting.  If 
inspectors are not so appointed, or if an appointed inspector fails 
to appear or fails or refuses to act at a meeting, the chairman of 
any meeting of stockholders may, and on the request of any stockholder 
or his proxy shall, appoint inspectors of election at the meeting.

     (e)  Any action required or permitted to be taken by the 
stockholders of the corporation must be effected at a duly called 
annual or special meeting of such holders and may not be effected 
by any consent in writing by such holders.


Article III

Board of Directors

Section 1.  Election of Directors.

     (a)  Number.  The authorized number of directors of the corporation 
shall be fixed from time to time by the board of directors but shall 
not be less than three (3).  The exact number of directors shall be 
determined from time to time either by a resolution or bylaw duly 
adopted by the board of directors.

     (b)  Classes of Directors.  The board of directors shall be and 
is divided into three classes:  Class I, Class II and Class III, which 
shall be as nearly equal in number as possible. Each director shall 
serve for a term ending on the date of the third annual meeting of 
stockholders following the annual meeting at which the director was 
elected; provided, however, that each initial director in Class I 
shall hold office until the annual meeting of stockholders in 1987; 
each initial director in Class II shall hold office until the annual 
meeting of stockholders in 1988; and each initial director in Class III 
shall hold office until the annual meeting of stockholders in 1989.  
Notwithstanding the foregoing provisions of this subsection (b), each 
director shall serve until his successor is duly elected and qualified 
or until his death, resignation or removal.

     (c)  Newly Created Directorships and Vacancies.  In the event of 
any increase or decrease in the authorized number of directors, the 
newly created or eliminated directorships resulting from such increase 
or decrease shall be apportioned by the board of directors among the 
three classes of directors so as to maintain such classes as nearly 
equal in number as possible.  No decrease in the number of directors 
constituting the board of directors shall shorten the term of any 
incumbent director.  Newly created directorships resulting from any 
increase in the number of directors and any vacancies on the board of 
directors resulting from death, resignation, disqualification, removal 
or other cause shall be filled by the affirmative vote of a majority 
of the remaining directors then in office (and not by stockholders), 
even though less than a quorum of the board of directors.  Any director 
elected in accordance with the preceding sentence shall hold office for 
the remainder of the full term of the class of directors in which the 
new directorship was created or the vacancy occurred and until such 
director's successor shall have been elected and qualified.

     (d)  Nomination of Directors.  Candidates for director shall be 
nominated either

          (i)  by the board of directors or a committee appointed by 
the board of directors or

          (ii)  by nomination at any such stockholders' meeting by or 
on behalf of any stockholder entitled to vote at such meeting provided 
that written notice of such stockholder's intent to make such 
nomination or nominations has been given, either by personal delivery 
or by United States mail, postage prepaid, to the secretary of the 
corporation not later than (1) with respect to an election to be 
held at an annual meeting of stockholders, ninety (90) days in advance 
of such meeting, and (2) with respect to an election to be held at a 
special meeting of stockholders for the election of directors, the 
close of business on the tenth (10th) day following the date on which 
notice of such meeting is first given to stockholders.  Each such 
notice shall set forth: (a) the name and address of the stockholder 
who intends to make the nomination and of the person or persons to be 
nominated; (b) a representation that the stockholder is a holder of 
record of stock of the corporation entitled to vote at such meeting 
and intends to appear in person or by proxy at the meeting to nominate 
the person or persons specified in the notice; (c) a description of 
all arrangements or understandings between the stockholder and each 
nominee and any other person or persons (naming such person or 
persons) pursuant to which the nomination or nominations are to be 
made by the stockholder; (d) such other information regarding each 
nominee proposed by such stockholder as would be required to be 
included in a proxy statement filed pursuant to the proxy rules of 
the Securities and Exchange Commission, had the nominee been nominated, 
or intended to be nominated, by the board of directors; and (e) the 
consent of each nominee to serve as a director of the corporation 
if so elected.  The presiding officer of the meeting may refuse to 
acknowledge the nomination of any person not made in compliance 
with the foregoing procedure.

     (e)  Removal.  Any director may be removed from office without 
cause but only by the affirmative vote of the holders of not less 
than seventy-five percent (75%) of the outstanding stock of the 
corporation entitled to vote generally in the election of directors, 
voting together as a single class.

     (f)  Preferred Stock Provisions.  Notwithstanding the foregoing, 
whenever the holders of any one or more classes or series of stock 
issued by this corporation having a preference over the common stock 
as to dividends or upon liquidation, shall have the right, voting 
separately by class or series, to elect directors at an annual or 
special meeting of stockholders, the election, term of office, filling 
of vacancies, nominations, terms of removal and other features of 
such directorships shall be governed by the terms of Article FOURTH 
of the certificate of incorporation and the resolution or resolutions 
establishing such class or series adopted pursuant thereto and such 
directors so elected shall not be divided into classes pursuant to 
Article SIXTH of the certificate of incorporation unless expressly 
provided by such terms.

Section 2.  Meetings of the Board of Directors.

     (a)  Regular Meetings.  Regular meetings of the board of directors

secretary, or by any other officer authorized by the board.  Such 
notice shall be given to each director personally or by mail, 
messenger, telephone or telegraph at his business or residence 
address.  Notice by mail shall be deposited in the United States

     (c)  Adjourned Meetings.  A majority of directors present at 
any regular or special meeting of the board of directors, whether or 
not constituting a quorum, may adjourn from time to time until the 
time fixed for the next regular meeting.  Notice of the time and 
place of holding an adjourned meeting shall not be required if the 
time and place are fixed at the meeting adjourned.

     (d)  Place of Meetings.  Unless a resolution of the board of 
directors, or the written consent of all directors given either before 
or after the meeting and filed with the secretary, designates a 
different place within or without the State of Delaware, meetings of 
the board of directors, both regular and special, shall be held at the 
corporation's offices at 100 N.E. Adams Street, Peoria, Illinois.

     (e)  Participation by Telephone.  Members of the board may 
participate in a meeting through use of conference telephone or similar 
communications equipment, so long as all members participating in such 
meeting can hear one another, and such participation shall constitute 
presence in person at such meeting.

     (f)  Quorum.  At all meetings of the board one-third of the 
total number of directors shall constitute a quorum for the transaction 
of business and the act of a majority of the directors 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 
or by the certificate of incorporation. A meeting at which a quorum is 
initially present may continue to transact business notwithstanding the 
withdrawal of directors, if any action is approved by at least a 
majority of the required quorum for such meeting.  Less than a quorum 
may adjourn any meeting of the board from time to time without notice.

Section 3.  Action Without Meeting.

the minutes of the proceedings of the board.

Section 4.  Compensation of Directors.

additional compensation for their services as directors.

Section 5.  Committees of the Board.

     There shall be such committees of the board of directors each 
consisting of two or more directors with such authority, subject to 
applicable law, as a majority of the board shall by resolution 
determine.  Committees of the board shall meet subject to the call 
of the chairman of each committee and shall prepare and file with the 
secretary minutes of their meetings.  Unless a committee shall by 
resolution establish a different procedure, notice of the time and 
place of committee meetings shall be given by the chairman of the 
committee, or at his request by the chairman of the board or by the 
secretary or an assistant secretary.  Such notice shall be given to 
each committee member personally or by mail, messenger, telephone or 
telegraph at his business or residence address at the times provided

entitled to notice of or to vote at any meeting of stockholders or any 
adjournment thereof, or entitled to receive payment of any dividend or 
other distribution or allotment of any rights or entitled to exercise 
any rights in respect of any change, conversion or exchange of stock 
or for the purpose of any other lawful action, the board may fix, in 
advance, a record date, which shall not be more than sixty (60) nor

date for the adjourned meeting.

     (c)  Stockholders on the record date are entitled to notice and 
to vote or to receive the dividend, distribution or allotment of
