              ---------------                                                   
     limitations prescribed by law and the limitation on authorized Preferred
     Stock stated above in this Article FOURTH, to provide for the issuance of
     shares of Preferred Stock in one or more series, and, by filing a
     certificate pursuant to the applicable law of the State of Delaware, to

     series, and to fix the designation, powers, preferences and rights of the
     shares of each such series and the qualifications, limitations or
     restrictions thereof.

 
          The authority of the Board of Directors with respect to each series of
     Preferred Stock shall include, but not be limited to, determination of the
     following:

               (a) The number of shares constituting that series and the
          distinctive designation of that series;

               (b) The dividend rate on the shares of that series, whether
          dividends shall be cumulative, and, if so, from which date or dates
          and the relative rights of priority, if any, of payment of dividends
          on shares of that series;

               (c) Whether that series shall have voting rights, in addition to
          the class voting rights provided by law, and, if so, the terms of such
          voting rights;

               (d) Whether that series shall have conversion privileges, and, if

               (e) Whether or not the shares of that 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;

               (f) Whether that series shall have a sinking fund for the
          redemption or purchase of shares of that series, and, if so, the terms
          and amount of such sinking fund;

               (g) The rights of the shares of that 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 that series; and

               (h) Any other absolute or relative rights, preferences or
          limitations of that series.

          Dividends on outstanding shares of Preferred Stock shall be paid or
     declared and set apart for payment before any dividends shall be paid or
     declared and set apart for payment on shares of Common Stock with respect
     to the same dividend period.

          The Preferred Stock shall be preferred over the Common Stock as to
     assets, and in the event of any liquidation or dissolution or winding up of
     the Corporation (whether voluntary or involuntary), the holders of the
     Preferred Stock shall be entitled to receive out of the assets of the
     Corporation available for distribution to its shareholders, whether from
     capital, surplus or earnings, the amount specified for each particular
     series, together with any dividends accrued or in arrears, for every share
     of their holdings of Preferred Stock before any distribution of the assets
     shall be made to the holders of Common Stock, and shall be entitled to no
     other or further distribution.  If upon any voluntary or 

                                      -2-

 
     involuntary liquidation, dissolution or winding up of the Corporation, the
     assets available for distribution to holders of shares of Preferred Stock
     of all series shall be insufficient to pay such holders the full
     preferential amount to which they are entitled, then such assets shall be
     distributed ratably among the shares of all series of Preferred Stock in
     accordance with the respective preferential amounts (including unpaid
     cumulative dividends, if any, as provided by the Board of Directors)
     payable with respect thereto.

          Neither the consolidation nor merger of the Corporation with or into
     any other corporation, nor any sale, lease, exchange or conveyance of all
     or any part of the property, assets or business of the Corporation shall be
     deemed to be a liquidation, dissolution or winding up of the Corporation
     within the meaning of this Article FOURTH.

          2.  Class A Common Stock and Class B Common Stock.  The powers,
              ---------------------------------------------              
     preferences, and rights of the Class A Common Stock and Class B Common
     Stock, and the qualifications, limitations and restrictions thereof, are
     fixed as follows:

               A.  Issuance; Payment and Assessability.  The shares of Class A
                   -----------------------------------                        
          Common Stock and Class B Common Stock may be issued by the Corporation
          from time to time for such consideration, having a value not less than
          par value, as may be fixed from time to time by the Board of Directors
          of the Corporation.  Any and all shares of Class A Common Stock and
          Class B Common Stock so issued for which the consideration so fixed
          has been paid or delivered to the Corporation shall be deemed fully
          paid stock and shall not be liable to any further call or assessment
          thereon, and the holders of said shares shall not be liable for any
          further payments in respect of such shares.

               B.  Dividends; Distributions; Stock Splits.  Holders of Class A
                   --------------------------------------

          distributions (including liquidating distributions) per share, whether
          in cash, in kind, in stock (including a stock split) or by any other
          means, when and as may be declared by the Board of Directors of the
          Corporation out of assets or funds of the Corporation legally
          available therefor.  Holders of Class B Common Stock shall be entitled
          to dividends or other distributions (including liquidating
          distributions) per share, whether in cash, in kind, in stock
          (including a stock split), or by any other means, equal to one-
          thirtieth (1/30th) of the amount per share declared by the Board of
          Directors of the Corporation for each share of Class A Common Stock,
          and such dividends or distributions with respect to the Class B Common
          Stock shall be paid in the same form and at the same time as dividends
          or distributions with respect to the Class A Common Stock; provided,
                                                                     ---------
          however, that, in the event of a stock split or stock dividend,
          -------                                                        
          holders of Class A Common Stock shall receive shares of Class A Common
          Stock and holders of Class B Common Stock shall receive shares of
          Class B Common Stock, unless otherwise specifically designated by
          resolution of the Board of Directors.

               C.  Voting.  Each holder of Class A Common Stock shall be
                   ------                                               
          entitled to one (1) vote for each share of Class A Common Stock
          standing in his name on the 

                                      -3-

 
          books of the Corporation. Each holder of Class B Common Stock shall be
          entitled to one-two-hundredth (1/200th) of one vote for eachshare of
          Class B Common Stock standing in his name on the books of the
          Corporation. Unless otherwise required by the Delaware General
          Corporation Law, the Class A Common Stock and the Class B Common Stock
          shall vote as a single class with respect to all matters submitted to
          a vote of shareholders of the Corporation.

               D.  Conversion.  Each share of Class A Common Stock may, at the
                   ----------                                                  
          option of the holder of record thereof and without payment of any
          consideration, be converted into thirty (30) fully paid and
          nonassessable shares of Class B Common Stock.  Any such conversion may
          be effected by any holder of Class A Common Stock surrendering such
          holder's certificate or certificates for the Class A Common Stock to
          be converted, duly endorsed, at the office of the Corporation or any
          transfer agent for the Class A Common Stock, together with a written
          notice to the Corporation that such holder elects to convert all or a
          specified whole number of shares of Class A Common Stock and stating
          the name or names in which such holder desires the certificate or
          certificates for the Class B Common Stock to be issued.  If so
          required by the Corporation, any certificate for shares surrendered
          for conversion shall be accompanied by instruments of transfer, in
          form satisfactory to the Corporation, duly executed by the holder of
          such shares or the duly authorized representative of such holder.
          Promptly thereafter, the Corporation shall issue and deliver or cause
          to be issued and delivered to such holder or such holder's nominee or
          nominees, a certificate or certificates for the number of shares of
          Class B Common Stock to which such holder shall be entitled as herein
          provided.  Such conversion shall be deemed to have been made at the
          close of business on the date of receipt by the Corporation or any
          such transfer agent of such certificate or certificates for Class A
          Common Stock and such notice, and the person or persons entitled to
          receive the Class B Common Stock issuable on such conversion shall be
          treated for all purposes as the record holder or holders of such Class
          B Common Stock on that date.

          The issuance of certificates for shares of Class B Common Stock
     issuable upon the conversion of shares of Class A Common Stock shall be
     made without charge to the converting holder; provided, however, that if
                                                   -----------------         
     any certificate is to be issued in a name other than that of the record
     holder of the shares being converted, the Corporation shall not be required
     to issue or deliver any such certificate unless and until the person
     requesting the issuance thereof shall have paid to the Corporation the
     amount of any tax that may be payable with respect to any transfer involved
     in the issuance and delivery of such certificate or has established to the
     satisfaction of the Corporation that such tax has been paid.

          The Corporation covenants that it will at all times reserve and keep
     available, solely for the purpose of issuance upon conversion of the
     outstanding shares of Class A 

                                      -4-

 
     Common Stock, a number of shares of Class B Common Stock equal to thirty
     (30) times the number of shares of Class A Common Stock then outstanding,
     in addition to the number of shares of Class B Common Stock then
     outstanding; provided, however, that nothing herein shall be construed to
                  -----------------                     
     preclude the Corporation from satisfying its obligation to issue shares of
     Class B Common Stock upon conversion of Class A Common Stock by delivery of
     purchased or redeemed shares of Class B Common Stock which are held in the
     treasury of the Corporation.

     FIFTH:    The following additional provisions are in furtherance and not
limitation of any power, privilege or purpose conferred or permitted by law,
this certificate or the by-laws:

     1. Except as may be otherwise expressly required by law, or the provisions
        of this Certificate or the by-laws, the Board of Directors of the
        Corporation shall have and may exercise, transact, manage, promote and
        carry on all of the powers, authorities, businesses, objectives and
        purposes of the Corporation.

     2. The election of directors need not be by ballot unless the by-laws so
        require.

     3. The Board of Directors of the Corporation is authorized and empowered to
        make, alter, amend and repeal the by-laws of the Corporation in any
        manner not inconsistent with the laws of the State of Delaware.

     4. The Board of Directors may fix from time to time the compensation of its
        members.

     5. The Corporation may indemnify or insure or both indemnify and insure any
        person who is or was a director, officer, employee or agent of the
        Corporation or, at its request, of another corporation, partnership,
        joint venture, trust or other enterprise, to the full extent provided or
        permitted by its by-laws, as from time to time amended, and to the full
        extent to which those indemnified may now or hereafter be entitled under
        any law, agreement, vote of stockholders or disinterested directors or
        otherwise.

     SIXTH:    No contract or other transaction between the Corporation and any
other corporation, and no act of the Corporation shall in any way be affected or
invalidated by the fact that any of the directors of the Corporation are
pecuniarily or otherwise interested in or are directors or officers of such
other corporation.  Any director individually, or any firm of which such
director may be a member, may be a party to or may be pecuniarily or otherwise
interested in any contract or transaction of the Corporation, provided that the
fact that he or such firm is so interested shall be disclosed or shall have been
known to the Board of Directors, or a majority thereof; and any director of the
Corporation, who is also a director or officer of such other corporation, or is
so interested, may be counted in determining the existence of a quorum at any
meeting of the Board of Directors of the Corporation which shall authorize such
contract or transaction, and may vote thereat to authorize any such contract or
transaction, with like force and effect, as if he were not such director or
officer of such other corporation or not so interested,

                                      -5-

 
     SEVENTH:  Any action which would otherwise be required or permitted to be
taken by the vote of stockholders at a meeting thereof may instead be taken by
the written consent of stockholders who would be entitled to vote upon such
action if such a meeting were held having not less than the percentage of the
total number of votes which would have been required to take such action at such
a meeting.

     EIGHTH:   No director of this Corporation shall have personal liability to
the Corporation or any of its stockholders for monetary damages for breach of
fiduciary duty as a director.  The foregoing provision shall not eliminate or
limit the liability of a director (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the General Corporation Law of the State of
Delaware or (iv) for any transaction from which the director derived an improper
personal benefit.  In the event that the General Corporation Law of the State of
Delaware is amended after approval of this Article by the stockholders so as to
authorize corporate action further eliminating or limiting the liability of
directors, the liability of a director of this Corporation shall thereupon be
eliminated or limited to the fullest extent permitted by the General Corporation
Law of the State of Delaware, as so amended from time to time.  The provisions
of this Article shall not be deemed to limit or preclude indemnification of a
director by the Corporation for any liability of a director which has not been
eliminated by the provisions of this Article.

     IN WITNESS WHEREOF, this Restated Certificate of Incorporation has been
executed by the Corporation this 10th day of August, 1998.
