     Certificate of Incorporation, are as follows:
      A.   PREFERRED STOCK

          (1)  Shares of Preferred Stock may be issued from time to time 
     in one or more series, each such series to have such distinctive 
     designation as shall be stated and expressed in the resolution or 
     resolutions adopted by the Board of Directors providing for the 
     initial issuance of shares of such series, and authority is

          by actions of the Board of Directors;

               (b)  To fix (i) the dividend rate of such series, (ii) 
          any limitation, restrictions or conditions on the payment of 
          dividends, including whether dividends shall be cumulative 
          and, if so, from which date or dates, (iii) the relative 
          rights of priority, if any, of payment of dividends on shares 
          of that series and (iv) the form of dividends, which shall be 
          payable either (A) in cash only, or (B) in stock only, or (C) 
          partly in cash and partly in stock, or (D) in stock or, at the 
          option of the holder, in cash (and in such case to prescribe 
          the terms and conditions of exercising such option), and to 
          make provision in case of dividends payable in stock for 
          adjustments of the dividend rate in such events as the Board 
          of Directors shall determine;

               (c)  To fix the price or prices at which, and the terms 
          and conditions on which, the shares of such series may be 
          redeemed by the Company;

               (d)  To fix the amount or amounts payable upon the shares 
          of such series in the event of any liquidation, dissolution or

          if any, of payment upon shares of such series;

               (e)  To determine whether or not the shares of such 
          series shall be entitled to the benefit of a sinking fund to

          so entitled, the amount of such fund and the manner of its 
          application;

               (f)  To determine whether or not the shares of such 
          series shall be made convertible into, or exchangeable for, 
          shares of any other class or classes of stock of the 
          Corporation or shares of any other series of Preferred Stock, 
          and, if made so convertible or exchangeable, the conversion 
          price or prices, or the rate or rates of exchange, and the 
          adjustments thereof, if any, at which such conversion or 
          exchange may be made, and any other terms and conditions of 
          such conversion or exchange;

               (g)  To determine whether or not the shares of such 
          series shall have any voting powers and, if voting powers are 
          so granted, the extent of such voting powers, provided that

          increased or decreased by the affirmative vote of the holders 
          of a majority of the Common Stock, voting as a class, and such 
          increase or decrease shall not require any actions by holders 
          of shares of Preferred Stock.  Except as otherwise provided by 
          statute or by a determination by the Board of Directors, the 
          holders  of shares of Preferred Stock, as such holders, shall 
          not have any right to vote in the election of directors or for 
          any other purpose; and such holders shall not be entitled to 
          notice of any meeting of stockholders at which they are not 
          entitled to vote;

               (h)  To determine whether or not the issue of any 
          additional shares of such series or of any other series in 
          addition to such series shall be subject to restrictions in 
          addition to the restrictions, if any, on the issue of 
          additional shares imposed in the resolution or resolutions 
          fixing the terms of any outstanding series of Preferred Stock 

          theretofore issued pursuant to this Section A and, if subject 
          to additional restrictions, the extent of such additional 
          restrictions; and

               (i)  Generally to fix the other rights, and any 
          qualifications, limitations or restrictions of such rights, of 
          such series; provided, however, that no such rights, 
          qualifications, limitations or restrictions shall be in 
          conflict with this Certificate of Incorporation or any 
          amendment hereof.

          (2)  Before any dividends shall be declared or paid or any 
     distribution ordered or made upon the Common Stock (other than a 
     dividend payable in Common Stock), the Corporation shall comply 
     with the dividend and sinking fund provisions, if any, of any 
     resolution or resolutions providing for the issue of any series of 
     Preferred Stock any shares of which shall at the time be 
     outstanding.  Subject to the foregoing sentence, the holders of 
     Common Stock shall be entitled, to the exclusion of the holders of 
     Preferred Stock of any and all series, to receive such dividends as 
     from time to time may be declared by the Board of Directors.

          (3)  Upon any liquidation, dissolution or winding up of the 
     Corporation, the holders of Preferred Stock of each series shall be 
     entitled to receive the amount to which such holders are entitled 
     as fixed with respect to such series, including all dividends 
     accumulated to the date of final distribution, before any payment 
     or distribution of assets of the Corporation shall be made to or 
     set apart for the holders of Common Stock; and after such payments 
     shall have been made to or set apart for the holders of Common 
     Stock; and after such payments shall have been made in full to the 
     holders of Preferred Stock, the holders of Common Stock shall be 
     entitled to receive any and all assets remaining to be paid or 
     distributed to stockholders and the holders of Preferred Stock 
     shall not be entitled to share therein.  For the purposes of this 
     paragraph, the voluntary sales, conveyance, lease, exchange or 
     transfer of all or substantially all the property or assets of the 
     Corporation or a consolidation or merger of the Corporation with 
     one or more other corporation (whether or not the Corporation is 
     the Corporation surviving such consolidation or merger) shall not 
     be deemed to be a liquidation, dissolution or winding up, voluntary 
     or involuntary.

          (4)  Subject to such limitations (if any) as may be fixed by 
     the Board of Directors with respect to such series of Preferred 
     Stock in accordance with paragraph (1) of this Section A, Preferred 
     Stock of each series may be redeemed at any time in whole or from 
     time to time in part, at the option of the Corporation, by vote of 
     the Board of Directors, at the redemption price thereof fixed in 
     accordance with said paragraph (1).  If less than all the 
     outstanding shares of Preferred Stock of such series are to be 
     redeemed, the shares to be redeemed shall be determined in such 
     manner as the Board of Directors shall prescribe.  At such time or 
     times prior to the date fixed for redemption as the Board of 
     Directors shall determine, written notice shall be mailed to each 
     holder of record of shares to be redeemed,  in a postage prepaid 
     envelope addressed to such holder at his address as shown by the 
     records of the Corporation, notifying such holders of the election 
     of the Corporation to redeem such shares and stating the date fixed 
     for the redemption thereof and calling upon such holder to 

     surrender to the Corporation on or after said date, at a place 
     designated in such notice, his certificate or certificates 
     representing the number of shares specified in such notice of 
     redemption.  On and after the date fixed in such notice of 
     redemption, each holder of shares of preferred Stock to be redeemed  
     shall present and surrender his certificate or certificates for 
     such shares to the Corporation at the place designated in such 
     notice and thereupon the redemption price of such shares shall be 
     paid to or on the order of the person whose name appears on the 
     records of the Corporation as the holder of the shares designated 
     for redemption.  In case less than all the shares represented by 
     any such certificate are redeemed a new certificate shall be issued 
     representing the unredeemed shares.  From and after the date fixed 
     in any such notice as the date of redemption (unless default shall 
     be made by the Corporation in payment of the redemption price) all 
     dividends on the shares of Preferred Stock designated for 
     redemption in such notice shall cease to accrue and all rights of 
     the holders thereof as stockholders of the Corporation, other than 
     to receive the redemption price, shall terminate and such shares 
     shall not thereafter be transferred (except with the consent of the 
     Corporation) on the books of the Corporation and such shares shall 
     not be deemed to be outstanding for any purpose whatsoever.  At any 
     time after the mailing of any such notice of redemption the 
     Corporation may deposit the redemption price of the shares 
     designated therein for redemption with a bank or trust company in 
     the United States of America, having capital and surplus of at 
     least $25,000,000 in trust for the benefit of the respective 
     holders of the shares designated for redemption but not yet 
     redeemed.  From and after the making of such deposit the sole right 
     of the holders of such shares shall be the right either to receive 
     the redemption price of such shares on and after such redemption 
     date, or, in the case of shares having conversion rights, the right 
     to convert the same at any time at or before the earlier of the 
     close of business on such redemption date or such prior date and 
     time at which the right to convert shall have expired; and except 
     for these rights, the shares of Preferred Stock so designated for 
     redemption shall not be deemed to be outstanding for any purpose 
     whatsoever.

          (5)  Shares of any series of Preferred Stock which have been 
     redeemed (whether through the operation of a sinking fund or 
     otherwise) or purchased by the Corporation, or which, if 
     convertible, have been converted into shares of stock of the 
     corporation of any other class or classes, may, upon appropriate 
     filing and recording to the extent required by law, have the status 
     of authorized and unissued shares of Preferred Stock and may be 
     reissued as part of such series or of any other series of Preferred 
     Stock, subject to such limitations (if  any) as may be fixed by the 
     Board of Directors with respect to such series of Preferred Stock 
     in accordance with paragraph (1) of this Section A.

    B.  COMMON STOCK

          (1)  Except as otherwise provided by (a) the Board of 
     Directors in fixing the voting rights of any series of the 
     Preferred Stock in accordance with Section A of this Article FOURTH 
     or (b) statute, voting power in the election of directors and for 
     all other purposes shall be vested exclusively in the holders of 
     the Common Stock.

          (2)  In the event of any liquidation, dissolution or winding 
     up of the Corporation, either voluntary or involuntary after 
     payment shall have been made to the holders of the Preferred Stock 
     of the full amount to which they shall be entitled pursuant to 
     paragraph (3) of Section A of this Article FOURTH, the holders of 
     Common Stock shall be entitled, to the exclusion of the holders of 
     the Preferred Stock of any and all series, to share, ratably 
     according to the number of shares of Common Stock held by them, in 
     all remaining assets of the Corporation available for distribution 
     to its stockholders.
          All persons who shall acquire stock in this Corporation shall 
     acquire the same subject to the provisions of this Certificate of 
     Incorporation, as amended.

     SECOND:  That at the Annual Meeting of Stockholders of the Company,  
which was duly called and held September 30, 1994 upon notice in 
accordance with Section 222 of the General Corporation Law of the State 
of Delaware, at which a quorum was present and acting throughout, said 
Amendment was approved by the affirmative vote of the number of shares 
required by law.
     THIRD:  That said Amendment was duly adopted in accordance with the 
provisions of Section 242 of the General Corporation Law of the State of 
Delaware.
     FOURTH:  That the capital of the Company will not be reduced under 
or by reason of said Amendment.
     IN WITNESS WHEREOF, the Company has caused its corporate seal to be 
affixed hereto and this Certificate to be signed by GILBERT F. AMELIO, 
President and Chief Executive Officer of the Company, and attested to be 
JOHN M. CLARK III, Secretary of the Company this 30th day of September,
