               (b)  Change, by amendment of the Certificate of
          Incorporation of the Company, as then in effect, or
          otherwise, the terms and provisions of the New Preferred

          of the holders thereof; provided, however, that if any such
          amendment is adverse to the rights and preferences of the
          holders of one or more, but less than all, of the series of

          New Preferred Stock or shares of any stock ranking pari
          passu with the New Preferred Stock as to dividends or
          liquidation rights, at the time outstanding, unless the
          Common Stock equity as defined in subdivision 2 of Division

          ranking prior to or pari passu with the New Preferred Stock
          as to dividends or liquidation rights, which will be
          outstanding after the issue of the shares or convertible
          securities proposed to be issued.

     4.  That subdivision 6-II of Division A of Article Fourth of the

               (b)  Sell, lease or exchange all or substantially all
          of the property and assets of the Company.
     
     No vote or consent of the holders of the New Preferred Stock
     shall be required under the provisions of this subdivision 6, if
     at or prior to the taking of any action described in this
     subdivision 6, provision is made for the retirement, by
     redemption or otherwise, of all shares of New Preferred Stock
     then outstanding.

     5.  That Division B of Article Fourth of the Restated Certificate of

     Preference Stock the full preferential amounts to which they are
     entitled, the holders of the Common Stock shall be entitled to receive
     pro rata all of the remaining assets of the Company available for
     distribution to its stockholders.

     6.  That thereafter pursuant to the aforesaid resolution of its Board
