The preferences, qualifications, limitations, restrictions and the special or
relative rights in respect of the shares of each class are:

SECTION A

The Preferred Shares

1.   The Preferred Shares may be issued in one or more series and with such
designation for each such series sufficient to distinguish the shares thereof
from the shares of all other series and classes, as shall be stated and
expressed in the resolution or resolutions providing for the issue of each such
series adopted by the Board of Directors.  The Board of Directors in any such
resolution or resolutions is hereby expressly authorized to divide the Preferred
Shares into series and to fix and determine the relative rights and preferences
of the shares of any series so established as to:

     (i)       The rate per annum at which the holders of shares shall be
               entitled to receive dividends.

     (ii)      The price at and the terms and conditions on which shares may be
               redeemed.

     (iii)     The amount payable upon shares in event of involuntary
               liquidation.

     (iv)      The amount payable upon shares in event of voluntary liquidation.

     (v)       The sinking fund provisions, if any, for the redemption or
               purchase of shares.

     (vi)      The terms and conditions on which shares may be converted, if the
               shares are issued with the privilege of conversion.

The Board of Directors may increase the number of shares designated for any
existing series by a resolution adding to such



                                        4



series authorized and unissued Preferred Shares not designated for any other
series.

2.   All preferred Shares of any one series shall be identical with each other
in all respects, except that shares of any one series issued at different times
as provided in paragraph 3 of this Section A, may differ as to the dates from
which dividends thereon shall be cumulative.

3.   Before any dividends on the Common Shares or on any other class or classes
of shares of the Corporation, ranking junior to the Preferred Shares with
respect to payment of dividends, shall be paid or declared or set apart for
payment, the holders of Preferred Shares shall be entitled to receive when and
as declared by the Board of Directors, cumulative cash dividends, out of any
funds legally available for the declaration of dividends and in the case of each
series at the rate per annum, and no more, for the particular series fixed in
the resolution or resolutions providing for the issue of such series of
Preferred Shares, adopted by the Board of Directors, payable quarterly on such
dates, in each year, as may be fixed in such resolution or resolutions.  With
respect to each series of the Preferred Shares, such dividends shall be
cumulative from the respective dates of issue thereof. No dividends shall be
paid on any series of the Preferred Shares in respect of any dividend period
unless all cumulative dividends accrued prior to said dividend period with
respect to all Preferred Shares of each other series shall have been paid or
declared and set aside for payment.

4.   The holders of Preferred Shares shall be entitled to vote as a class and
otherwise as provided by law.

5.   Preferred shares which have been redeemed or shall have been purchased,
converted or otherwise acquired by the Corporation may thereafter be reissued
under such terms and conditions, not inconsistent with the provisions of this
Section A, as the Board of Directors may thereafter determine.

6.   In the event of any voluntary or involuntary liquidation, dissolution or
winding up of the Corporation, and before any distribution of the assets of the
Corporation shall be made to or set apart for the holders of the Common Shares
or of any other class of shares of the Corporation ranking junior to the
Preferred Shares with respect to payment of dividends or upon dissolution,
liquidation or winding up of the Corporation, the holders of the shares of each
series of the Preferred Shares then outstanding shall be entitled to receive
payment of such amount, as shall be stated and expressed in the resolution or
resolutions adopted by the Board of Directors providing for the issue of such
series; but such holders upon receipt of such payment shall be entitled to no
further payment.



                                        5



7.   In case of any liquidation, dissolution or winding up of the Corporation,
if the amounts payable with respect to all series of Preferred Shares then
outstanding are not paid in full, the shares of all series of the Preferred
Shares shall share proportionately in accordance with the respective amounts
which would be payable on said shares if all amounts payable were paid in full.

8.   A consolidation or merger of the Corporation with or into one or more
corporations shall not be deemed to be a liquidation, dissolution or winding up
within the meaning of this Section A.

SECTION B

The Common Shares

1.   Subject to the limitations set forth in Section A of this Restated Article
R-V, the holders of Common Shares shall be entitled to dividends if, when and as
the same shall be declared by the Board of Directors out of funds of the
Corporation legally available thereof.

2.   The holders of Common Shares shall be entitled to vote as provided by law.

SECTION C

The Preferred and Common Shares

No holder of shares of any class of the Corporation shall be entitled as of
right to subscribe to or purchase any additional or increased shares of any
class (whether now or hereafter authorized), or obligations convertible into any
class or classes of shares (whether now or hereafter authorized), or shares of
any class convertible into shares of any other class or classes (whether now or
hereafter authorized), or obligations, shares or other securities carrying
warrants or rights to subscribe to shares of the Corporation of any class or
classes (whether now or hereafter authorized), but any and all shares, bonds,
debentures or other securities or obligations, whether or not convertible into
shares or carrying warrants entitling the holders thereof to subscribe to
shares, may be issued, sold or disposed of from time to time by the board of
Directors to such persons, firms or corporations and for such consideration (so
far as may be permitted by law, by the Articles of Incorporation of the
Corporation, and by the terms of any resolution creating any series of Preferred
Shares) as the Board of Directors shall from time to time in its absolute
discretion determine. Among other things the Board of Directors shall have the
right at any time and from time to time to offer, sell and issue shares of any
class of the Corporation, or obligations, shares or other securities



                                        6



carrying warrants or rights to subscribe to shares of the Corporation of any
class or classes, to employees of the Corporation and to employees of
subsidiaries of the Corporation without first offering the same to its share
holders, for such prices or considerations, and upon such terms and conditions
as the Board of Directors shall from time to time determine, and upon any such
issuance and sale, or plan or proposal to issue and sell, the Board of Directors
may classify employees as in its discretion it may deem advisable, and may
differentiate between classes, and exclude any class from participation.  The
fact that an employee may be a director or an officer of the Corporation, or any
of its subsidiaries, shall not disqualify him from participation as an employee
in any such issuance or sale to employees.



RESTATED ARTICLE R-VI

1.   A director of the corporation shall not be personally liable to the
     corporation or its shareholders for monetary damages for breach of
     fiduciary duty as a director, except for liability (i) for any breach
     of the director's duty of loyalty to the corporation or its
     shareholders, (ii) for acts or omissions not in good faith or that
     involve intentional misconduct or a knowing violation of law, (iii)
     under Section 8.65 of the Illinois Business Corporation Act, or (iv)
     for any transaction from which the director derived an improper
     personal benefit; provided that the foregoing provision shall not
     eliminate or limit the liability of a director for any act or omission
     occurring before the date this provision became effective.

2.   Any person who was or is a party, or is threatened to be made a party
     to any threatened, pending or completed action, suit or proceeding,
     whether civil, criminal, administrative or investigative, by reason of
     the fact that he or she is or was a director, officer, employee or
     agent of the corporation, or who is or was serving at the request of
     the corporation as a director, officer, employee or agent of another
     corporation, partnership, joint venture, trust or other enterprise,
     shall, in the case of persons who are or were directors or officers of
     the corporation, and may, as to such other persons, be indemnified
     (and the corporation shall, in the case of persons who are or were
     directors or officers of the corporation, and may, as to such other
     persons, advance expenses incurred in defending such actions, suits or
     proceedings) to the fullest extent now or hereafter permitted by law.



                                        7



3.   The foregoing right of indemnification and advancement of expenses
     shall not be deemed exclusive of any other rights to which those
     seeking indemnification or advancement of expenses may be entitled
     under any bylaw, agreement, vote of shareholders or disinterested
     directors or otherwise.
