holders of a majority  of the stock  having  voting  power  present in person or
represented  by proxy shall decide any  question  brought  before such  meeting,
unless the question is one upon which by express provision of the statutes or of
the  certificate  of  incorporation,  a different vote is required in which case
such express provision shall govern and control the decision of such question.

                  (c) The conduct of all meetings of the stockholders  generally

presidents  in that  order  and in order of their  election,  shall  preside  as

stockholders,  each  holder of common  stock  shall be  entitled  to one vote in
person or by proxy for each share of common  stock held by the  stockholder.  No
proxy shall be voted after three years from its date unless  otherwise  provided
in the proxy,  and, except where the transfer books of the corporation have been
closed or a date has been fixed as a record  date for the  determination  of its
stockholders  entitled to vote, no share of stock shall be voted at any election
for directors which has been transferred on the books of the corporation  within
twenty (20) days next preceding such election of directors. In all elections for
directors each stockholder  shall have the right to vote, in person or by proxy,

         Section 8. (a) Each share standing in the name of another  corporation,
domestic or foreign, may be voted by such officer, agent or proxy as the by-laws
of such corporation may prescribe or, in the absence of such by-law  provisions,
as the board of directors of such corporation may determine.

                  (b) Shares  standing  in the name of a deceased  person may be
voted by his  administrator  or executor  either in person or by proxy.  Persons
holding  stock in a fiduciary  capacity may vote the shares so held in person or
by  proxy.  Shares  standing  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 name if authority so to do
be contained  in an  appropriate  order of the court by which such  receiver was
appointed. A stockholder whose shares are pledged shall be entitled to vote such
shares in person or by proxy, unless in the transfer by the pledgor on the books
of the  corporation he has expressly  empowered the pledgee to vote thereon,  in
which  case  only the  pledgee  or his proxy  may  represent  the stock and vote
thereon.

                  (c)  Shares  of stock  of this  corporation  belonging  to the
corporation shall not be voted, directly or indirectly, at any meeting and shall
not be counted in  determining  the total  number of  outstanding  shares at any
given time, but such shares held by the corporation in a fiduciary  capacity may
be voted and shall be counted in  determining  the total  number of  outstanding
shares at any given time.

                                  Voting Lists

         Section 9. The officer or agent  having  charge of the stock ledger for
the shares of the  corporation  shall  prepare and make,  at least ten (10) days
before each meeting of the stockholders at which directors are to be elected,  a
complete list of the stockholders entitled to vote at such meeting,  arranged in
alphabetical  order with the address of and the number of shares  registered  in
the name of each stockholder.  Such list shall be open to the examination of any
stockholder  during  ordinary  business  hours for a period of at least ten (10)
days prior to such  meeting at the place  where the  meeting is to be held or at
the office of the corporation in Chicago,  Illinois. Such list shall be produced
and kept at the time and place of the meeting  during the whole time thereof and
shall be subject to the inspection of any  stockholder  who may be present.  The
original  stock  ledger  shall  be  prima  facie  evidence  as to  who  are  the
stockholders entitled to examine such stock ledger and to vote at any meeting of
the stockholders.


                            Closing of Transfer Books

         Section 10. The board of directors may close the stock  transfer  books
of the corporation for a period not exceeding sixty (60) days preceding the date
of any meeting of  stockholders  or the date of payment of any dividend,  or the
date for the  allotment of rights or the date when any change or  conversion  or
exchange of capital  stock shall go into effect,  or for a period not  exceeding
sixty (60) days in connection with obtaining the consent of stockholders for any
purpose. In lieu of closing the stock transfer books as aforesaid,  the board of
directors may fix in advance a date, not exceeding sixty (60) days preceding the
date of any meeting of stockholders, or the date of the payment of any dividend,
or the  date for the  allotment  of  rights,  or the date  when  any  change  or
conversion  or exchange  of capital  stock  shall go into  effect,  or a date in
connection with obtaining such consent,  as a record date for the  determination
of the stockholders entitled to notice of, and to vote at, any such meeting, and
any adjournment thereof, or entitled to receive payment of any such dividend, or
to any such  allotment  of rights,  or to exercise  the rights in respect of any
such change,  conversion or exchange of capital stock,  or to give such consent,
and in such  case  such  stockholders  and only  such  stockholders  as shall be
stockholders of record on the date so fixed shall be entitled to such notice of,
and to vote at, such meeting and any adjournment  thereof, or to receive payment
of such dividend,  or to receive such  allotment of rights,  or to exercise such
rights,  or to give  such  consent,  as the  case  may be,  notwithstanding  any
transfer of any stock on the books of the corporation after any such record date
fixed as aforesaid.


                          Advance Notice of Nominations

         Section  11.  Subject  to such  rights of the  holders  of any class or
series of preferred stock as shall be prescribed in the Restated  Certificate of
Incorporation or in the resolutions of the Board of Directors  providing for the
issuance  of any  such  class or  series,  only  persons  who are  nominated  in
accordance  with the  procedures  set forth in this Section 11 shall be eligible
for election as, and to serve as, directors. Nominations of persons for election
to the Board of Directors may be made at a meeting of the  stockholders at which
directors are to be elected (a) by or at the direction of the Board of Directors
or (b) by any stockholder of the Corporation entitled to vote at such meeting in

Such  nominations,  other than those made by or at the direction of the Board of
Directors,  shall be  preceded  by  timely  advance  notice  in  writing  to the
Secretary of the  Corporation.  To be timely,  a  stockholder's  notice shall be
delivered to the Secretary at the principal executive offices of the Corporation
not later than the close of business on the 60th day nor earlier  than the close
of  business  on the 90th day prior to the first  anniversary  of the  preceding
year's annual meeting; provided, however, that in the event that the date of the
annual  meeting  is more than 30 days  before or more  than 60 days  after  such
anniversary  date,  notice by the  stockholder to be timely must be so delivered
not  earlier  than the close of  business  on the 90th day prior to such  annual
meeting  and not later than the close of  business  on the later of the 60th day
prior to such annual  meeting or the 10th day  following the day on which public
announcement of the date of such meeting is first made by the Corporation. In no
event  shall the public  announcement  of an  adjournment  of an annual  meeting
commence a new time period for the giving of a stockholder's notice as described
above. A  stockholder's  notice to the Secretary  shall set forth (x) as to each
person whom the stockholder  proposes to nominate for election or re-election as
a director,  (I) the name, age,  business address and residence  address of such
person,  (ii) the principal  occupation or employment of such person,  (iii) the
number of shares of each class of capital stock of the Corporation  beneficially
owned by such person, and (iv) the written consent of such person to having such
person's  name placed in nomination at the meeting and to serve as a director if
elected,  and (y) as to the  stockholder  giving  the  notice,  (I) the name and
address,  as they appear on the Corporation's  books, of such  stockholder,  and

are then  beneficially  owned by the stockholder.  The presiding  officer of the
meeting of stockholders shall determine whether the requirements of this Section
11 have been met with respect to any nomination or intended  nomination.  If the
presiding officer determines that any nomination was not made in accordance with
the  requirements  of this Section 11, he or she shall so declare at the meeting
and the defective nomination shall be disregarded.


                     Advance Notice of Stockholder Proposals

         Section 12. At an annual  meeting of  stockholders,  only such business
shall be conducted,  and only such proposals  shall be acted upon, as shall have
been brought  before the annual  meeting (a) by or at the direction of the Board
of Directors or (b) by any  stockholder of the Corporation who complies with the
requirements  of this Section 12 and as shall  otherwise be proper  subjects for
stockholder  action  and shall be  properly  introduced  at the  meeting.  For a
proposal to be properly  brought before an annual meeting by a stockholder,  the
stockholder  must have given  timely  advance  notice  thereof in writing to the
Secretary of the  Corporation.  To be timely,  a  stockholder's  notice shall be
delivered to the Secretary at the principal executive offices of the Corporation
not later than the close of business on the 60th day nor earlier  than the close
of  business  on the 90th day prior to the first  anniversary  of the  preceding
year's annual meeting; provided, however, that in the event that the date of the
annual  meeting  is more than 30 days  before or more  than 60 days  after  such
anniversary  date,  notice by the  stockholder to be timely must be so delivered
not  earlier  than the close of  business  on the 90th day prior to such  annual
meeting  and not later than the close of  business  on the later of the 60th day
prior to such annual  meeting or the 10th day  following the day on which public
announcement of the date of such meeting is first made by the Corporation. In no
event  shall the public  announcement  of an  adjournment  of an annual  meeting
commence a new time period for the giving of a stockholder's notice as described
above. A stockholder's notice to the Secretary shall set forth as to each matter
the stockholder proposes to bring before the annual meeting (w) a description of
the proposal desired to be brought before the annual meeting and the reasons for
conducting  such business at the annual  meeting,  (x) the name and address,  as
they  appear on the  Corporation's  books,  of the  stockholder  proposing  such
business and any other  stockholders  known by such stockholder to be supporting
such  proposal,  (y) the class and number of shares of the  Corporation's  stock
which are  beneficially  owned by the stockholder on the date of such notice and
(z) any financial  interest of the  stockholder in such proposal.  The presiding
officer of the annual meeting shall determine  whether the  requirements of this
Section  12 have  been met with  respect  to any  stockholder  proposal.  If the
presiding  officer  determines  that a  stockholder  proposal  was  not  made in
accordance  with the terms of this Section 12, he or she shall so declare at the
meeting and any such proposal shall not be acted upon at the meeting.

         At a special meeting of stockholders, only such business shall be acted
upon as shall have been set forth in the notice  relating  to the  meeting or as
shall constitute matters incident to the conduct of the meeting as the presiding
officer of the meeting shall determine to be appropriate.

resolution  or as may be fixed in a notice of the  meeting or as may be fixed in
any waiver of notice signed by all of the directors.

         Section 7. No notice of the holding of any regular meeting of the board
of directors is required.  Written notice of any special  meeting shall be given
