                    ----------------

               The voting rights of the respective classes of shareholders of
          this corporation otherwise entitled to vote hereunder and, the manner
          in which such voting rights may be exercised shall not be governed by
          Wisconsin

 
          Business Corporation Law Section 180.1131 notwithstanding that the
          subject matter to be voted upon might otherwise be subject thereto.

          (5)  Right of First Refusal -- Class C Common Shares
               -----------------------------------------------

               No holder of the Class C Common Shares may sell, encumber or
          transfer for value, any Class C Common Shares without first depositing
          the certificate(s) evidencing such shares with the Corporation, duly
          endorsed for transfer, and simultaneously notifying the Corporation,
          in writing, of the proposed transaction including the identity of the
          transferee and the price or other consideration to be paid. Within
          thirty (30) days following such deposit and notification, the
          Corporation may purchase such Class C Common Shares by paying to the
          holder of such shares the lower of the price offered by the proposed
          transferee, or one (1c) cent per share by delivery of the purchase
          price to the holder of such shares, failing which the shares evidenced
          by the certificate(s) so deposited may be sold in accordance with the
          proposed transaction. The Corporation shall not be obliged to accept,
          transfer or to re-register certificates evidencing any Class C Common
          Shares without an affidavit of the transferor and transferee or other
          evidence to the effect that such transfer is without value. A transfer
          for value, for purposes of this paragraph, shall include a transfer by
          any person which is part of a series of transfers or transactions in
          which the transferee, or a party or entity related to, or affiliated
          with, the transferee provides value, directly or indirectly, to the
          transferor or a person or entity related to, or affiliated with, the
          transferor.

     (b)  Preferred Shares
          ----------------

          (1)  The Preferred Shares may be issued from time to time in one or
     more series. The Board of Directors is hereby authorized, by filing an
     Articles of Amendment to the Corporation's Articles of Incorporation,
     without vote of shareholders and in accordance with Section 180.0602 of the
     Wisconsin Business Corporation Law (a "Preferred Shares Amendment"), to fix
     or alter from time to time, the designation, powers, preferences and rights
     of the shares of each such series, and the qualifications, limitations or
     restrictions thereof so far as not inconsistent with the provisions of this
     Article 5 and to the full extent now or hereafter permitted by the laws of
     the State of Wisconsin, including the following:

               (A) The distinctive designation of such series and the number of
          shares which shall constitute such series,

 
          which number may be increased (except where otherwise provided by the
          Board of Directors in creating such series) or decreased (but not
          below the number of shares thereof then outstanding) from time to time
          by like action of the Board of Directors;

               (B)  The annual rate or rates of dividends payable on shares of
          such series, whether dividends shall be cumulative and, if so, the
          date or dates from which dividends shall be cumulative on the shares
          of such series, the preferences, restrictions, limitations and
          conditions upon the payment of dividends, and the dates on which
          dividends, if declared, shall be payable;

               (C)  Whether shares of such series shall be redeemable and, if
          so, the terms and conditions of such redemption, including the date or
          dates upon or after which they shall be redeemable, and the amount per
          share payable in case of redemption, which amount may vary under
          different conditions and at different redemption dates;

               (D)  The rights of the shares of such series in the event of
          voluntary or involuntary liquidation, dissolution or winding up of the
          corporation, and the relative rights of priority, if any, of payment
          of shares of such series;

               (E)  Whether shares of such series shall have a purchase,
          retirement or sinking fund for the purchase, retirement, or redemption
          of shares of such series and, if so, the terms and provisions thereof;

               (F)  Whether shares of such series shall have conversion
          privileges and, if so, the terms and provisions thereof, including
          provision for adjustment of the conversion rate in such events as the
          Board of Directors shall determine;

               (G)  Whether shares of such series shall have voting rights, in
          addition to voting rights provided by law, and, if so, the terms and
          provisions thereof; and

               (H)  Any other preferences and relative, participating, optional
          or other special rights, and qualifications, limitations or
          restrictions thereof.

          (2) The holders of the Preferred Shares of each series shall be
     entitled to receive dividends, when and as declared by the Board of
     Directors from the funds legally therefor, as they may be entitled to in
     accordance with the Preferred Share Amendment adopted by the Board of
     Directors providing for the

 
     issuance of such series, payable on such dates as may be fixed in such
     Amendment. So long as there shall be outstanding any shares of Preferred
     Shares of any series entitled to cumulative dividends pursuant to any such
     Preferred Share Amendment providing for the issue of such series, no
     dividend, whether in cash or property, shall be paid or declared, nor shall
     any distribution be made on the Common Shares (Class A or Class C), nor
     shall any Common Shares be purchased, redeemed or otherwise acquired for
     value by the Corporation (except as provided in Section 5) if at the time
     of making such payment, declaration, distribution, purchase, redemption or
     acquisition, the Corporation shall be in default with respect to any
     dividend payable on or obligation to maintain a purchase, retirement or
     sinking fund with respect to or to redeem shares of Preferred Shares of any
     series. The foregoing provisions of this Subsection (b)(2) shall not,
     however, apply to a dividend payable in Common Shares or to the acquisition
     of Common Shares in exchange for or through the application of the proceeds
     of the sale of shares of Common Shares. Subject to the foregoing and to any
     further limitations prescribed in accordance with the provisions of this
     Section (b) of this Article 5, the Board of Directors may declare, out of
     any funds legally available therefor, dividends upon the then outstanding
     Common Shares and the Preferred Shares of any series shall not be entitled
     to participate therein.

          (3)  In the event of any voluntary or involuntary liquidation,
     dissolution or winding up of the Corporation, the holders of the Preferred
     Shares of each series shall be entitled to receive, out of the assets of
     the Corporation available for distribution to its stockholders before any
     distribution of assets shall be made to the holders of the Common Shares,
     the amount per share, if any, fixed by the Board of Directors in the
     Preferred Shares Amendment, plus in each such case an amount equal to any
     cumulative dividends thereon to the date of final distribution to the
     holders of the Preferred Shares, and the holders of the Common Shares shall
     be entitled, to the exclusion of the holders of the Preferred Shares of any
     and all series to participate ratably in all the assets of the Corporation
     then remaining in accordance with their respective rights and preferences.
     If upon any liquidation, dissolution or winding up of the Corporation the
     assets available for distribution shall be insufficient to pay the holders
     of all outstanding shares of Preferred Shares the full amounts to which
     they shall be entitled, the holders of Preferred Shares of all series shall
     participate ratably in any distribution of assets according to the
     respective amounts which would be payable in respect of the Preferred
     Shares held by them upon such distribution if all amounts payable in
     respect of the Preferred Shares of all series were paid in full. Neither
     the statutory merger nor consolidation of the Corporation into or with any
     other

 
     corporation, nor the statutory merger or consolidation of any other
     corporation into or with the Corporation, nor a sale, transfer or lease of
     all or any part of the assets of the Corporation, shall be deemed to be a
     liquidation, dissolution or winding up of the corporation within the
     meaning of this Subsection (3).

          (4)  The Corporation, at the option of the Board of Directors, may
     redeem the whole or any part of the Preferred Shares of any series at the
     price or prices and on the terms and conditions provided in the Preferred
     Shares Amendment adopted by the Board of Directors providing for the issue
     of such series.

          (5)  Anything herein or in any Preferred Shares Amendment adopted by
     the Board of Directors providing for the issue of any series of Preferred
     Shares contained to the contrary notwithstanding, the rights of the holders
     of all classes of stock of the Corporation in respect of dividends and
     purchase, retirement or sinking funds, if any, shall at all times be
     subject to the power of the Board of Directors from time to time to set
     aside such reserves and to make such other provisions, if any, as the Board
     of Directors shall deem to be necessary or advisable for working capital,
     for expansion of the Corporation's business (including the acquisition of
     real and personal property for the purpose) and for any other purpose of
     the Corporation.

          (6)  Except as otherwise provided by the statutes of the State of
     Wisconsin or by the Preferred Shares Amendment adopted by the Board of
     Directors providing for the issue of any series of Preferred Shares, the
     holders of the Preferred Shares shall have no right to vote. The holders of
     the Preferred Shares shall not be entitled to receive notice of any meeting
     of shareholders at which they are not entitled to vote or consent.

          (7)  Except as otherwise provided by the statutes of the State of
     Wisconsin or by the Preferred Shares Amendment adopted by the Board of
     Directors providing for the issue of any series of Preferred Shares, the
     vote of the holders of all or any portion of the Preferred Shares, as a
     class, shall not be required for any action whatsoever to be taken or
     authorized by the shareholders of the Corporation, including any amendment
     of the Articles of Incorporation.

     (c)  Waiver of Preemptive Rights
          ---------------------------

          No holder of any of the shares of this Corporation shall be entitled,
     as of right, to purchase or subscribe for any unissued stock of any class,
     or any additional shares of any class to be issued by reason of any
     increase of the authorized

 
     shares of the Corporation of any class, or bonds, certificates of
     indebtedness, debentures or other securities convertible into shares of the
     Corporation, or carrying any right to purchase any stock of any class and
     any unissued shares, or such additional authorized issue of any shares or
     other securities convertible into shares or carrying any rights to purchase
     such shares may be issued and disposed of, pursuant to resolutions of the
     Board of Directors, to such persons, firms, corporations or associations
     and upon such other terms as may be deemed advisable by the Board of
     Directors in the exercise of its discretion.

     III. Each of the amendments was adopted on the 15th day of August, 1996, in
accordance with Section 180.1003 of the Wisconsin Business Corporation Law.

     Executed in duplicate this 15th day of August, 1996.
