        connection  with  the  Disposition by the  Corporation  of  all  of  its
        properties  and  assets  in one transaction) to any  person,  entity  or
        group  (other  than (A) the holders of all outstanding shares  of  Steel
        Stock  on  a pro rata basis or (B) any person, entity or group in  which
        the   Corporation,  directly  or  indirectly,  owns  a  majority  equity
        interest), the Corporation shall, on or prior to the first Business  Day

           available  therefor, redeem the number of whole shares of outstanding
           Steel  Stock that has an aggregate average Market Value,  during  the
           ten-Business   Day  period  beginning  on  the  first  Business   Day
           following  such  consummation,  closest  to  the  value  of  the  Net
           Proceeds  of  such Disposition, for cash and/or securities  or  other
           property received as proceeds of such Disposition in an amount  equal
           to such Net Proceeds; or

             (C) exchange each outstanding share of Steel Stock for a number  of
           fully  paid and nonassessable shares of Marathon Stock or,  if  there
           are  no shares of Marathon Stock outstanding on the Exchange Date and
           shares  of Delhi Stock are then outstanding, of Delhi Stock equal  to
           110%  of  the  average daily ratio (calculated to  the  nearest  five
           decimal  places) of the Market Value of one share of Steel  Stock  to
           the  Market  Value of one share of Marathon Stock  or  one  share  of
           Delhi  Stock,  as  the  case  may be, during  such  ten-Business  Day
           period.

        For purposes of this Section 2(b)(i):

           (x)  as of any date, ''substantially all of the properties and assets
        of  the  U.S. Steel Group'' shall mean a portion of such properties  and
        assets  that  represents  at  least 80% of either  of  the  then-current
        market   value  of,  or  the  aggregate  revenues  for  the  immediately
        preceding  twelve  fiscal quarterly periods of the  Corporation  derived
        from, the properties and assets of the U.S. Steel Group as of such  date
        (excluding the properties and assets of any person, entity or  group  in
        which  the  Corporation,  directly  or  indirectly,  owns  less  than  a
        majority equity interest);

           (y)  if  immediately  after any event, the Corporation,  directly  or
        indirectly,  owns less than a majority equity interest  in  any  person,
        entity or group in which the Corporation, directly or indirectly,  owned
        a  majority equity interest immediately prior to the occurrence of  such
        event,  a  Disposition of all of the properties and assets of  the  U.S.
        Steel  Group  owned by such person, entity or group shall be  deemed  to
        have occurred; and

           (z) in the case of a Disposition of properties and assets in a series
        of  related transactions, such Disposition shall not be deemed  to  have
        been   consummated  until  the  consummation  of  the   last   of   such
        transactions.

           (ii)  The Board of Directors may, by a majority vote of the directors
        then  in office, at any time after a dividend or redemption pursuant  to
        clause  (A) or (B), respectively, of Section 2(b)(i), declare that  each
        of  the  remaining outstanding shares of Steel Stock shall be exchanged,

        pursuant   to  Section  2(d)(i),  for  a  number  of  fully   paid   and
        nonassessable  shares of Marathon Stock or, if there are  no  shares  of
        Marathon  Stock  outstanding on such Exchange Date and shares  of  Delhi
        Stock  are then outstanding, of Delhi Stock, equal to 110% of the Market
        Value  Ratio as of the fifth Business Day prior to the date such  notice
        is  mailed  to  such  holders. For purposes of the  preceding  sentence,

        following  (calculated  to  the nearest five decimal  places):  (A)  the
        average  ratio  of S/X for the five-Business Day period ending  on  such
        date,  (B)  the  quotient of (1) the sum of (w) four times  the  average
        ratio  of S/X for the five-Business Day period ending on such date,  (x)
        three  times  the  average  ratio of S/X for the  next  preceding  five-
        Business  Day  period, (y) two times the average ratio of  S/X  for  the
        next  preceding  five-Business Day period and (z) the average  ratio  of
        S/X  for the next preceding five-Business Day period, divided by (2) ten
        and  (C)  if the dividend pursuant to clause (A) of Section 2(b)(i)  was
        declared  and paid or the redemption pursuant to (B) of Section  2(b)(i)
        was  made  prior  to  the  commencement of the most  recently  completed
        fiscal  quarter of the Corporation, the average ratio of  S/X  for  such
        fiscal quarter, where S is the Market Value of one share of Steel  Stock
        and  X  is the Market Value of one share of Marathon Stock or one  share
        of Delhi Stock, as the case may be.

           (iii)  At any time on or after the date on which the Corporation  has
        transferred  all of the assets and liabilities of the U.S.  Steel  Group
        (and  no  other  assets or liabilities) to a wholly owned subsidiary  of
        the  Corporation  (the ''U.S. Steel Group Subsidiary''),  the  Board  of
        Directors  may,  in its sole discretion and by a majority  vote  of  the
        directors  then  in  office,  provided  that  there  are  funds  of  the
        Corporation  legally  available  therefor,  declare  that  all  of   the
        outstanding  shares  of Steel Stock shall be exchanged  on  an  Exchange
        Date  set  forth  in  a  notice to holders of Steel  Stock  pursuant  to
        Section  2(d)(i), for all of the outstanding shares of common  stock  of
        the  U.S.  Steel Group Subsidiary, on a pro rata basis,  each  of  which
        shall, upon such issuance, be fully paid and nonassessable.

           (iv)  After  any  Exchange  Date or  Redemption  Date  on  which  all
        outstanding  Steel Stock was exchanged or redeemed, any share  of  Steel
        Stock  that  is  issued  on conversion or exercise  of  any  Convertible
        Securities  shall, immediately upon issuance pursuant to such conversion
        or  exercise and without any notice or any other action on the  part  of
        the  Corporation or its Board of Directors or the holder of  such  share
        of Steel Stock:

             (A) in the event the then-outstanding Steel Stock was exchanged for
           Marathon  Stock  or  Delhi Stock on such Exchange  Date  pursuant  to
           Section 2(b)(i) or 2(b)(ii), be exchanged for the kind and amount  of
           shares  of  capital stock and other securities and  property  that  a
           holder  of  such  Convertible Security would have  been  entitled  to
           receive  pursuant to the terms of such Convertible Security had  such
           terms  provided  that the conversion privilege in effect  immediately
           prior  to any exchange by the Corporation of any of its capital stock
           for  shares  of any other capital stock of the Corporation  would  be
           adjusted  so  that  the  holder  of  any  such  Convertible  Security
           thereafter  surrendered for conversion would be entitled  to  receive
           the  number of shares of capital stock of the Corporation  and  other
           securities  and  property he would have owned  immediately  following
           such  action had such Convertible Security been converted immediately
           prior thereto; or

             (B)  in the event the then-outstanding Steel Stock was redeemed  in
           whole  pursuant  to clause (B) of Section 2(b)(i)  or  exchanged  for
           common  stock of the U.S. Steel Group Subsidiary pursuant to  Section
           2(b)(iii),  be  redeemed, to the extent of funds of  the  Corporation
           legally available therefor, for $.01 in cash.

             The  provisions  of clause (A) of this Section 2(b)(iv)  shall  not
           apply  to  the extent that equivalent adjustments are otherwise  made
           pursuant to the provisions of such Convertible Securities.

       (c) Exchange and Redemption of Delhi Stock.

           (i)  In the event of the Disposition, in one transaction or a  series
        of  related transactions, by the Corporation of all or substantially all

        connection  with  the  Disposition by the  Corporation  of  all  of  its
        properties  and  assets  in one transaction) to any  person,  entity  or
        group  (other  than (A) the holders of all outstanding shares  of  Delhi
        Stock  on  a pro rata basis or (B) any person, entity or group in  which
        the   Corporation,  directly  or  indirectly,  owns  a  majority  equity
        interest), the Corporation shall, on or prior to the first Business  Day

           cash  and/or in securities or other property received as proceeds  of
           such Disposition to the holders of Delhi Stock in an amount equal  to
           the  product  of  the  Delhi Fraction and the Net  Proceeds  of  such
           Disposition; or

             (B)  to  the extent that there are funds of the Corporation legally
           available  therefor, redeem the number of whole shares of outstanding
           Delhi  Stock that has an aggregate average Market Value,  during  the
           ten-Business   Day  period  beginning  on  the  first  Business   Day

           such Disposition in an amount equal to such product; or

             (C) exchange each outstanding share of Delhi Stock for a number  of
           fully  paid and nonassessable shares of Marathon Stock or,  if  there
           are  no  shares  of Marathon Stock outstanding on such Exchange  Date

           Steel  Stock,  as  the  case  may be, during  such  ten-Business  Day

        properties and assets of the Delhi Group as of such date (excluding  the
        properties  and  assets  of any person, entity or  group  in  which  the
        Corporation,  directly or indirectly, owns less than a  majority  equity
        interest);

        transactions.

           (ii)  The Board of Directors may, by a majority vote of the directors
        then  in office, at any time after a dividend or redemption pursuant  to

           (iv)  For purposes of Section 2(c)(ii) and (iii), the ''Market  Value
        Ratio'',  as  of  any  date,  shall mean the highest  of  the  following
        (calculated  to the nearest five decimal places): (A) the average  ratio

        no  other  assets  or liabilities) to a wholly owned subsidiary  of  the
        Corporation  (the  ''Delhi Group Subsidiary''), the Board  of  Directors
        may,  in  its  sole discretion and by a majority vote of  the  directors

        legally  available therefor, declare that all of the outstanding  shares
        of  Delhi  Stock shall be exchanged on an Exchange Date set forth  in  a
        notice  to  holders of Delhi Stock pursuant to Section  2(d)(i),  for  a
        number  of  outstanding  shares  of common  stock  of  the  Delhi  Group
        Subsidiary equal to the product of the Delhi Fraction and the number  of
        all  outstanding  shares of common stock of the Delhi Group  Subsidiary,
        on  a  pro rata basis, each of which shall, upon such issuance, be fully
        paid and nonassessable.

           (vi)  After  any  Exchange  Date or  Redemption  Date  on  which  all
        outstanding  Delhi Stock was exchanged or redeemed, any share  of  Delhi
        Stock  that  is  issued  on conversion or exercise  of  any  Convertible
        Securities  shall, immediately upon issuance pursuant to such conversion
        or  exercise and without any notice or any other action on the  part  of
        the  Corporation or its Board of Directors or the holder of  such  share
        of Delhi Stock:

             (A) in the event the then-outstanding Delhi Stock was exchanged for
           Marathon  Stock  or  Steel Stock on such Exchange  Date  pursuant  to
           Section  2(c)(i), 2(c)(ii) or 2(c)(iii), be exchanged  for  the  kind
           and  amount  of  shares  of capital stock and  other  securities  and
           property  that a holder of such Convertible Security would have  been
           entitled  to  receive  pursuant  to the  terms  of  such  Convertible
           Security  had  such terms provided that the conversion  privilege  in
           effect  immediately prior to any exchange by the Corporation  of  any
           of  its  capital stock for shares of any other capital stock  of  the
           Corporation  would  be  adjusted so  that  the  holder  of  any  such
           Convertible Security thereafter surrendered for conversion  would  be
           entitled  to  receive the number of shares of capital  stock  of  the
           Corporation  and  other securities and property he would  have  owned
           immediately following such action had such Convertible Security  been
           converted immediately prior thereto; or

             (B)  in the event the then-outstanding Delhi Stock was redeemed  in
           whole  pursuant  to clause (B) of Section 2(c)(i)  or  exchanged  for
           common  stock  of  the  Delhi Group Subsidiary  pursuant  to  Section
           2(c)(v),  be  redeemed,  to the extent of funds  of  the  Corporation
           legally available therefor, for $.01 in cash.

           The provisions of clause (A) of this Section 2(c)(vi) shall not apply
        to  the  extent that equivalent adjustments are otherwise made  pursuant
        to the provisions of such Convertible Securities.

        (d) General Exchange and Redemption Provisions.

           (i)  In  the  event of any exchange or redemption  pursuant  to  this
        Section  2  (other  than Section 2(a)(ii), 2(b)(iv), or  2(c)(vi)),  the
        Corporation  shall  cause to be given to each holder  of  the  class  of
        Common  Stock to be so exchanged or redeemed a notice stating  (A)  that
        shares of such class of Common Stock shall be exchanged or redeemed,  as
        the  case may be, (B) the Exchange Date or the Redemption Date,  (C)  in
        the  event of a partial redemption of Steel Stock or Delhi Stock, as the
        case may be, pursuant to clause (B) of Section 2(b)(i) or clause (B)  of
        Section  2(c)(i), respectively, the number of shares of Steel  Stock  or
        Delhi  Stock,  as  the case may be, to be redeemed,  (D)  the  kind  and
        amount  of  shares of capital stock or cash and/or securities  or  other
        property  to  be received by such holder with respect to each  share  of
        such class of Common Stock held by such holder, including details as  to
        the  calculation thereof, (E) the place or places where certificates for
        shares of such class of Common Stock, properly endorsed or assigned  for
        transfer (unless the Corporation shall waive such requirement),  are  to
        be  surrendered for delivery of certificates for shares of such  capital
        stock  or cash and/or securities or other property and (F) that, subject
        to  Section  2(d)(iv) hereof, dividends on such shares of  Common  Stock
        will  cease to be paid as of such Exchange Date or Redemption Date. Such
        notice  shall  be  sent by first-class mail, postage prepaid,  not  less
        than  30  nor more than 60 days prior to the Exchange Date or Redemption
        Date,  as  the case may be, and in any case to each holder of the  class
        of  Common  Stock to be exchanged or redeemed, at such holder's  address
        as  the  same  appears on the stock transfer books of  the  Corporation.
        Neither  the  failure  to mail such notice to any particular  holder  of
        such  class  of  Common Stock nor any defect therein  shall  affect  the
        sufficiency  thereof with respect to any other holder of such  class  of
        Common Stock.

           (ii)  If  less than all of the outstanding shares of Steel  Stock  or
        Delhi  Stock, as the case may be, are to be redeemed pursuant to  clause
        (B)  of  Section 2(b)(i) or clause (B) of Section 2(c)(i), respectively,
        such  shares  shall be redeemed by the Corporation pro  rata  among  the
        holders of such class of Common Stock or by such other method as may  be
        determined by the Board of Directors to be equitable.

           (iii)  The  Corporation shall not be required  to  issue  or  deliver
        fractional  shares  of  any class of capital  stock  or  any  fractional
        securities  to  any  holder  of  any class  of  Common  Stock  upon  any
        exchange,  redemption, dividend or other distribution pursuant  to  this
        Section 2. If more than one share of any class of Common Stock shall  be
        held  at the same time by the same holder, the Corporation may aggregate
        the  number  of  shares  of any class of capital  stock  that  shall  be
        issuable or the amount of securities that shall be deliverable  to  such
        holder  upon  any  exchange, redemption, dividend or other  distribution
        (including  any  fractions of shares or securities). If  the  number  of
        shares  of  any  class  of  capital stock or the  amount  of  securities
        remaining  to  be  issued or delivered to any holder  of  any  class  of
        Common  Stock is a fraction, the Corporation shall, if such fraction  is
        not  issued  or  delivered  to such holder, pay  a  cash  adjustment  in
        respect of such fraction in an amount equal to the fair market value  of
        such  fraction on the fifth Business Day prior to the date such  payment
        is  to  be  made. For purposes of the preceding sentence, ''fair  market
        value''  of any fraction shall be (i) in the case of any fraction  of  a
        share  of capital stock of the Corporation, the product of such fraction
        and  the Market Value of one share of such capital stock and (ii) in the
        case  of  any other fractional security, such value as is determined  by
        the Board of Directors.

           (iv)  No  adjustments in respect of dividends shall be made upon  the
        exchange  or  redemption  of any shares of any class  of  Common  Stock;
        provided,  however,  that if the Exchange Date or Redemption  Date  with
        respect  to any class of Common Stock shall be subsequent to the  record
        date  for  the  payment of a dividend or other distribution  thereon  or
        with  respect  thereto, the holders of shares of such  class  of  Common
        Stock at the close of business on such record date shall be entitled  to
        receive  the  dividend or other distribution payable on or with  respect
        to  such  shares on the date set for payment of such dividend  or  other
        distribution, notwithstanding the exchange or redemption of such  shares
        or  the Corporation's default in payment of the dividend or distribution
        due on such date.

           (v) Before any holder of shares of any class of Common Stock shall be
        entitled  to  receive certificates representing shares  of  any  capital
        stock  or  cash  and/or securities or other property to be  received  by
        such  holder  with respect to such shares of such class of Common  Stock
        pursuant  to this Section 2, such holder shall surrender at such  office
        as  the  Corporation shall specify certificates for such shares of  such
        class  of  Common  Stock,  properly endorsed or  assigned  for  transfer
        (unless  the  Corporation shall waive such requirement). The Corporation
        will  as  soon  as  practicable  after such  surrender  of  certificates
        representing  such shares of such class of Common Stock deliver  to  the
        person for whose account such shares of such class of Common Stock  were
        so   surrendered,   or   to   his  nominee  or  nominees,   certificates
        representing the number of whole shares of the kind of capital stock  or
        cash  and/or securities or other property to which he shall be  entitled
        as  aforesaid,  together  with any fractional  payment  contemplated  by
        Section  2(d)(iii).  If  less than all of the shares  of  any  class  of
        Common  Stock,  represented by any one certificate are to  be  redeemed,
        the  Corporation  shall  issue and deliver a  new  certificate  for  the
        shares of such class of Common Stock not redeemed.

           (vi)  From and after any applicable Exchange Date or Redemption Date,
        all  rights of a holder of shares of any class of Common Stock that were
        exchanged  or redeemed shall cease except for the right, upon  surrender
        of  the  certificates  representing such  shares  of  Common  Stock,  to
        receive  certificates  representing shares of the  kind  and  amount  of
        capital  stock  or  cash and/or securities or other property  for  which
        such  shares  were exchanged or redeemed, together with  any  fractional
        payment  contemplated by Section 2(d)(iii) and rights  to  dividends  as
        provided  in  Section  2(d)(iv).  No  holder  of  a  certificate,   that
        immediately  prior  to the applicable Exchange Date  for  any  class  of
        Common Stock represented shares of such class of Common Stock, shall  be
        entitled  to receive any dividend or other distribution with respect  to
        shares  of  any  kind of capital stock into which such class  of  Common
        Stock  was exchanged until surrender of such holder's certificate for  a
        certificate or certificates representing shares of such kind of  capital
        stock.  Upon  such  surrender, there shall be paid  to  the  holder  the
        amount of any dividends or other distributions (without interest)  which
        theretofore  became  payable with respect to a  record  date  after  the
        Exchange  Date, but that were not paid by reason of the foregoing,  with
        respect  to  the  number of whole shares of the kind  of  capital  stock
        represented  by  the  certificate  or  certificates  issued  upon   such
        surrender.  From  and  after an Exchange Date for any  class  of  Common
        Stock,  the  Corporation  shall,  however,  be  entitled  to  treat  the
        certificates  for  such class of Common Stock that  have  not  yet  been
        surrendered  for exchange as evidencing the ownership of the  number  of
        whole  shares of the kind or kinds of capital stock for which the shares
        of  such  class  of Common Stock represented by such certificates  shall
        have  been  exchanged,  notwithstanding the failure  to  surrender  such
        certificates.

           (vii)  The  Corporation will pay any and all  documentary,  stamp  or
        similar  issue or transfer taxes that may be payable in respect  of  the
        issue  or delivery of any shares of capital stock on exchange of  shares
        of  any  class  of  Common Stock pursuant hereto. The Corporation  shall
        not,  however, be required to pay any tax that may be payable in respect
        of  any  transfer involved in the issue and delivery of  any  shares  of
        capital  stock  in  a name other than that in which the  shares  of  the
        class  of  Common Stock so exchanged were registered, and no such  issue
        or  delivery  shall be made unless and until the person requesting  such
        issue  has  paid to the Corporation the amount of any such tax,  or  has
        established  to the satisfaction of the Corporation that  such  tax  has
        been paid.

     3. Voting Rights.

        (a) Except as provided in clauses (c), (d) or (e) below, the holders  of
     all  classes of Common Stock shall vote together as a single class  on  all
     matters  as to which holders of Common Stock are entitled to vote.  On  all
     matters  to  be  voted  on by the holders of all classes  of  Common  Stock
     together  as  a single class, (i) each outstanding share of Marathon  Stock
     shall  have  one  vote, (ii) each outstanding share of any other  class  of
     Common   Stock  shall  have  a  number  of  votes  equal  to  the  quotient
     (calculated to the nearest three decimal places), as of the fifth  Business
     Day  prior  to  the  applicable record date or as of any  other  applicable
     date,  of  (A) the sum of (1) four times the average ratio of X/Y  for  the
     five-Business  Day  period ending on such fifth  Business  Day,  (2)  three
     times  the  average  ratio of X/Y for the next preceding five-Business  Day
     period, (3) two times the average ratio of X/Y for the next preceding five-
     Business  Day  period  and  (4) the average  ratio  of  X/Y  for  the  next
     preceding  five-Business Day period, divided by (B) ten,  where  X  is  the
     Market  Value  of such class of Common Stock and Y is the Market  Value  of
     the  Marathon Stock or if there are no shares of Marathon Stock outstanding
     on  such  record  or  other applicable date or on any  of  the  twenty-five
     Business  Days  prior thereto, the sum of the Market Values  of  the  Steel
     Stock and of the Delhi Stock; provided that until the Delhi Stock has  been
     traded  regular way on the New York Stock Exchange for at least twenty-five
     Business  Days,  each outstanding share of the Delhi  Stock  shall  have  a
     number of votes equal to the ratio of A/B (calculated to the nearest  three
     decimal places), where A is the average of the high and low reported  sales
     prices of a share of the Delhi Stock on the New York Stock Exchange, and  B
     is  the  average of the high and low reported sales prices of  a  share  of
     Marathon  Stock  or, if there are no shares of Marathon Stock  outstanding,
     the  sum  of  the average of the high and low reported sales  prices  of  a
     share  of  the Steel Stock and a share of the Delhi Stock on such Exchange,
     in  each  case  on  the  Effective Date,  or  on  the  first  Business  Day
     thereafter on which shares of the Delhi Stock are traded on such  Exchange.
     If  shares of only one class of Common Stock are outstanding, each share of
     that class shall have one vote.

        (b)  Unless the vote or consent of a greater number of shares shall then
     be  required  by law, the vote or consent of the holders of a  majority  of
     all of the shares of any class of Common Stock then outstanding, voting  as
     a  separate  class,  shall  be  necessary  for  authorizing,  effecting  or
     validating the merger or consolidation of the Corporation into or with  any
     other  corporation if such merger or consolidation would  adversely  affect
     the  powers or special rights of such class of Common Stock either directly
     by  amendment  of this Restated Certificate of Incorporation or  indirectly
     by  requiring the holders of such class to accept or retain, in such merger
     or  consolidation,  anything other than (i) shares of such  class  or  (ii)
     shares  of  the surviving or resulting corporation having, in either  case,
     powers  and special rights identical to those of such class prior  to  such
     merger or consolidation.

        (c)  Unless the vote or consent of a greater number of shares shall then
     be  required by law, the vote or consent of the holders of at least  662/3%
     of  all of the shares of Steel Stock then outstanding, voting as a separate
     class, shall be necessary for:

           (i)  the declaration or payment of any dividend on, or the making  of
        any  other  payment or distribution with respect to any  shares  of  any
        other  class  of Common Stock, if such dividend, payment or distribution
        is  to  be  made with (A) proceeds from the Disposition of  any  of  the
        properties and assets of the U.S. Steel Group or (B) any portion  of  an
        equity  interest  in  a person, entity or group that  owns  any  of  the
        properties or assets of the U.S. Steel Group; or

           (ii)  the  use,  or  reservation for use, of any  proceeds  from  the
        Disposition  of  any  of the properties and assets  of  the  U.S.  Steel
        Group,  or any of the properties and assets acquired with such proceeds,
        in  any  business of the Corporation other than a business of  the  U.S.
        Steel Group;

     provided such vote shall not be required if such proceeds are loaned  at  a
     rate   or   rates  representative  of  actual  borrowings  and   short-term
     investments by the Corporation.

        (d)  Unless the vote or consent of a greater number of shares shall then
     be  required by law, the vote or consent of the holders of at least  662/3%
     of  all the shares of Marathon Stock then outstanding, voting as a separate
     class, shall be necessary for:

           (i)  the declaration or payment of any dividend on, or the making  of
        any  other  payment or distribution with respect to, any shares  of  any
        other  class  of Common Stock, if such dividend, payment or distribution
        is  to  be  made with (A) proceeds from the Disposition of  any  of  the
        properties  and assets of the Marathon Group or (B) any  portion  of  an
        equity  interest  in  a person, entity or group that  owns  any  of  the
        properties and assets of the Marathon Group; or

           (ii)  the  use,  or  reservation for use, of any  proceeds  from  the
        Disposition  of any of the properties and assets of the Marathon  Group,
        or  any of the properties and assets acquired with such proceeds, in any
        business  of  the  Corporation other than a  business  of  the  Marathon
        Group;

     provided  such vote shall not be required to the extent such  proceeds  are
     loaned  at  a rate or rates representative of actual borrowings and  short-
     term investments by the Corporation.

        (e)  Unless the vote or consent of a greater number of shares shall then
     be  required by law, the vote or consent of the holders of at least  662/3%
     of  all of the shares of Delhi Stock then outstanding, voting as a separate
     class, shall be necessary for:

           (i)  the declaration or payment of any dividend on, or the making  of
        any  other  payment or distribution with respect to any  shares  of  any
        other  class  of Common Stock, if such dividend, payment or distribution
        is  to  be  made with (A) proceeds from the Disposition of  any  of  the
        properties  and  assets  of the Delhi Group or (B)  any  portion  of  an
        equity  interest  in  a person, entity or group that  owns  any  of  the
        properties or assets of the Delhi Group; or

           (ii)  the  use,  or  reservation for use, of any  proceeds  from  the
        Disposition of any of the properties and assets of the Delhi  Group,  or
        any  of  the properties and assets acquired with such proceeds,  in  any
        business of the Corporation other than a business of the Delhi Group;

     provided such vote shall not be required if such proceeds are loaned  at  a
     rate   or   rates  representative  of  actual  borrowings  and   short-term
     investments by the Corporation.

        (f) The number of authorized shares of any class of Common Stock may  be
     increased  or  decreased (but not below the number of shares  thereof  then
     outstanding)  by  the affirmative vote of the holders of shares  of  Common
     Stock having a majority of the votes entitled to be cast by the holders  of
     all  classes  of Common Stock, voting together as provided for  in  Section
     3(a) and without a separate vote of the holders of any class.

  4.  Liquidation  Rights.  In  the  event of the  dissolution,  liquidation  or
  winding-up  of the Corporation, whether voluntary or involuntary, after  there
  shall have been paid or set apart for the holders of Preferred Stock the  full
  preferential  amounts  to  which  they  are  entitled,  the  holders  of   the
  outstanding shares of each class of Common Stock shall be entitled to  receive
  a  fraction of the funds of the Corporation remaining for distribution to  its
  stockholders, where such fraction is equal to the quotient of (A) the  sum  of
  (1)  four  times  the  average ratio of x/y for the five-Business  Day  period
  ending  on  the  Business Day prior to the date of the public announcement  of
  (I)  a voluntary dissolution, liquidation or winding-up by the Corporation  or
  (II)  the  institution  of  the  proceeding for the  involuntary  dissolution,
  liquidation  or  winding-up of the Corporation, (2) three  times  the  average
  ratio  of  x/y for the next preceding five-Business Day period, (3) two  times
  the  average ratio of x/y for the next preceding five-Business Day period  and
  (4)  the average ratio of x/y for the next preceding five-Business Day period,
  divided  by  (B) ten, where x is the Market Capitalization of  such  class  of
  Common  Stock, and y is the aggregate Market Capitalization of all classes  of
  Common   Stock.   For   purposes   of   the   preceding   sentence,   ''Market
  Capitalization''  of  any class of Common Stock on  any  day  shall  mean  the
  product of (i) the Market Value of such class of Common Stock on such day  and
  (ii)  the number of shares of such class of Common Stock outstanding  on  such
  day.

     5.  Definitions. As used in this Division I, the following terms shall have
  the  following meanings (with terms defined in the singular having  comparable

  provided or the context otherwise requires:

        ''Available Delhi Dividend Amount'', on any date, shall mean the product
     of  the Delhi Fraction and either (a) the greater of (i) an amount equal to

     the  Delhi Group that are no longer included as part of the Delhi Group  as
     a  result of any such dividend, distribution or repurchase pursuant to  the
     proviso  to the definition of ''Delhi Group'' and (E) any other adjustments
     to  stockholders'  equity  of  the Delhi  Group  made  in  accordance  with
     generally  accepted  accounting  principles,  less  (y)  the  sum  of   the
     aggregate  stated capital of all outstanding Preferred Stock attributed  to
     the  Delhi  Group  and  the  quotient of the aggregate  par  value  of  all
     outstanding Delhi Stock divided by the Delhi Fraction and (ii)  the  excess
     of  the fair market value of the net assets of the Delhi Group over the sum
     of  the  aggregate  stated  capital  of  all  outstanding  Preferred  Stock
     attributed to the Delhi Group, and the quotient of the aggregate par  value

    Section 2. Dividends and Distributions.

        (A)  Subject  to  the prior and superior rights of the  holders  of  any
     shares  of any series of Preferred Stock ranking prior and superior to  the
     shares  of  Series A Junior Preferred Stock with respect to dividends,  the
     holders  of shares of Series A Junior Preferred Stock shall be entitled  to
     receive,  when, as and if declared by the Board of Directors out  of  funds
     legally  available for the purpose, quarterly dividends payable in cash  on
     the  first  day of March, June, September and December in each  year  (each
     such  date  being  referred  to  herein as a ''Quarterly  Dividend  Payment
     Date''), commencing on the first Quarterly Dividend Payment Date after  the
     first  issuance  of  a  share or fraction of a share  of  Series  A  Junior
     Preferred  Stock,  in  an amount per share (rounded to  the  nearest  cent)
     equal  to  the  greater of (a) $5.00 or (b) subject to  the  provision  for
     adjustment hereinafter set forth, 100 times the aggregate per share  amount
     of  all  cash  dividends,  and  100 times the aggregate  per  share  amount
     (payable  in  kind) of all non-cash dividends or other distributions  other
     than  a dividend payable in shares of Common Stock or a subdivision of  the
     outstanding  shares of Common Stock (by reclassification or otherwise),  to
     be  or  being declared on the Common Stock, par value $1.00 per  share,  of
     the  Corporation (the ''Common Stock'') with respect to the  same  dividend
     period.  If  the Quarterly Dividend Payment Date is a Saturday,  Sunday  or
     legal  holiday then such Quarterly Dividend Payment Date shall be the first
     immediately  preceding  calendar day which is not  a  Saturday,  Sunday  or
     legal  holiday.  In  the  event the Corporation shall  at  any  time  after
     October  10,  1989  (the  ''Rights  Declaration  Date'')  (i)  declare  any
     dividend  on Common Stock payable in shares of Common Stock, (ii) subdivide
     the  outstanding  Common  Stock, or (iii) combine  the  outstanding  Common
     Stock  into  a smaller number of shares, then in each such case the  amount
     to  which  holders  of  shares  of Series A  Junior  Preferred  Stock  were
     entitled  immediately prior to such event under clause (b) of the preceding
     sentence  shall  be adjusted by multiplying such amount by a  fraction  the
     numerator  of  which  is the number of shares of Common  Stock  outstanding
     immediately after such event and the denominator of which is the number  of
     shares  of  Common Stock that were outstanding immediately  prior  to  such
     event.

        (B)  The  Corporation shall declare a dividend or  distribution  on  the
     Series  A  Junior  Preferred  Stock  as provided  in  paragraph  (A)  above
     immediately  prior  to the time it declares a dividend or  distribution  on
     the  Common  Stock  (other  than a dividend payable  in  shares  of  Common
     Stock);  provided that, in the event no dividend or distribution  shall  be
     declared on the Common Stock with respect to a particular dividend  period,
     a  dividend of $5.00 per share on the Series A Junior Preferred Stock shall
     nevertheless  be  payable  on  such Quarterly Dividend  Payment  Date  with
     respect to such quarterly period.

        (C)  Dividends  shall begin to accrue and be cumulative  on  outstanding
     shares  of  Series  A  Junior Preferred Stock from the  Quarterly  Dividend
     Payment  Date next preceding the date of issue of such shares of  Series  A
     Junior  Preferred Stock, unless the date of issue of such shares  is  prior
     to  the record date for the first Quarterly Dividend Payment Date, in which
     case  dividends on such shares shall begin to accrue from the date of issue
     of  such  shares,  or  unless the date of issue  is  a  Quarterly  Dividend
     Payment  Date  or is a date after the record date for the determination  of
     holders of shares of Series A Junior Preferred Stock entitled to receive  a
     quarterly  dividend  and before such Quarterly Dividend  Payment  Date,  in
     either  of  which  events  such dividends shall  begin  to  accrue  and  be
     cumulative  from such Quarterly Dividend Payment Date. Accrued  but  unpaid
     dividends  shall not bear interest. Dividends paid on the shares of  Series
     A  Junior Preferred Stock in an amount less than the total amount  of  such
     dividends  at  the  time  accrued  and payable  on  such  shares  shall  be
     allocated pro rata on a share-by-share basis among all such shares  at  the
     time  outstanding.  The Board of Directors may fix a record  date  for  the
     determination  of  holders  of shares of Series A  Junior  Preferred  Stock
     entitled  to  receive  payment  of  a  dividend  or  distribution  declared
     thereon, which record date shall be no more than 30 days prior to the  date
     fixed  for  the payment thereof. Dividends in arrears may be  declared  and
     paid  at  any  time,  without reference to any Quarterly  Dividend  Payment
     Date,  to  holders of record on such date, not exceeding 45 days  preceding
     the payment date thereof, as may be fixed by the Board of Directors.

        (D)  Except  as hereinafter provided, no dividends shall be declared  or
     paid  or  set apart for payment on the shares of Series A Junior  Preferred
     Stock  for any period if the Corporation shall be in default in the payment
     of  any  dividends (including cumulative dividends, if applicable)  on  any
     shares  of Preferred Stock ranking, as to dividends, prior to the Series  A
     Junior   Preferred  Stock,  unless  the  same  shall  be  contemporaneously
     declared and paid.

        (E)  Dividends payable on the Series A Junior Preferred  Stock  for  the
     initial  dividend  period and for any period less  than  a  full  quarterly
     period, shall be computed on the basis of a 360-day year of 30-day months.

     Section  3.  Voting  Rights.  The holders of  shares  of  Series  A  Junior
  Preferred Stock shall have the following voting rights:

        (A)  Each  share  of Series A Junior Preferred Stock shall  entitle  the
     holder  thereof  to one vote on all matters submitted  to  a  vote  of  the
     stockholders  of the Corporation. The holders of Series A Junior  Preferred
     Stock  shall  be entitled to notice of all meetings of the stockholders  of
     the Corporation.

        (B) Except as otherwise provided herein or by law, the holders of shares
     of  Series  A  Junior Preferred Stock and the holders of shares  of  Common
     Stock  shall vote together as one class on all matters submitted to a  vote
     of stockholders of the Corporation.

        (C)  If,  on the date used to determine stockholders of record  for  any
     meeting  of  stockholders  for the election  of  directors,  a  default  in
     preference  dividends  on the Preferred Stock shall exist,  the  number  of
     directors constituting the Board of Directors of the Corporation  shall  be
     increased  by  two, and the holders of the Preferred Stock  of  all  series
     (whether  or  not the holders of such series of Preferred  Stock  would  be
     entitled  to  vote  for  the  election of  directors  if  such  default  in
     preference dividends did not exist), shall have the right at such  meeting,
     voting  together  as  a  single class without  regard  to  series,  to  the
     exclusion  of  the holders of Common Stock, to elect two directors  of  the
     Corporation  to  fill  such  newly  created  directorships.  Each  director
     elected  by  the  holders  of shares of Preferred Stock  (herein  called  a
     ''Preferred Director''), shall continue to serve as such director  for  the
     full  term for which he shall have been elected, notwithstanding that prior
     to  the  end of such term a default in preference dividends shall cease  to
     exist.  Any Preferred Director may be removed by, and shall not be  removed
     except  by, the vote of the holders of record of the outstanding shares  of
     Preferred  Stock,  voting  together as a single  class  without  regard  to
     series,  at a meeting of the stockholders, or of the holders of  shares  of
     Preferred  Stock,  called for the purpose. So long  as  a  default  in  any
     preference dividends on the Preferred Stock shall exist (i) any vacancy  in
     the  office  of a Preferred Director may be filled (except as  provided  in
     the  following  clause  (ii)) by an instrument in  writing  signed  by  the
     remaining  Preferred Director and filed with the Corporation  and  (ii)  in
     the  case  of  the removal of any Preferred Director, the  vacancy  may  be
     filled  by  the vote of the holders of the outstanding shares of  Preferred
     Stock,  voting together as a single class without regard to series, at  the
     same  meeting at which such removal shall be voted. Each director appointed
     as  aforesaid by the remaining Preferred Director shall be deemed, for  all
     purposes  hereof, to be a Preferred Director. Whenever the term  of  office
     of  the  Preferred  Directors  shall  end  and  no  default  in  preference
     dividends  shall exist, the number of directors constituting the  Board  of
     Directors  of the Corporation shall be reduced by two. For the purposes  of
     this  paragraph (C), a ''default in preference dividends'' on the Preferred
     Stock  shall be deemed to have occurred whenever the amount of accrued  and
     unpaid  dividends  upon  any  series  of  the  Preferred  Stock  shall   be
     equivalent  to  six  full  quarterly dividends  or  more,  and,  having  so
     occurred, such default shall be deemed to exist thereafter until, but  only
     until,  all accrued dividends on all shares of Preferred Stock of each  and
     every  series  then  outstanding shall have  been  paid  through  the  last
     Quarterly Dividend Payment Date.

     Section 4. Certain Restrictions.

        (A)  Whenever  quarterly dividends or other dividends  or  distributions
     payable  on  the Series A Junior Preferred Stock as provided in  Section  2
     are  in arrears, thereafter and until all accrued and unpaid dividends  and
     distributions,  whether  or  not declared, on shares  of  Series  A  Junior
     Preferred  Stock outstanding shall have been paid in full, the  Corporation
     shall not:

           (i)  declare  or  pay dividends on, make any other  distributions  on
        (other  than  a dividend in Common Stock or in any other  stock  of  the
        Corporation ranking junior to the Series A Junior Preferred Stock as  to
        dividends  and  upon liquidation, dissolution or winding  up  and  other
        than  as  provided in subparagraph (ii) of this section), or  redeem  or
        purchase  or  otherwise acquire for consideration (except by  conversion
        into  or  exchange for stock of the Corporation ranking  junior  to  the
        Series  A  Junior Preferred Stock as to dividends and upon  dissolution,
        liquidation  or winding up), any shares of stock ranking junior  (either
        as  to dividends or upon liquidation, dissolution or winding up) to  the
        Series A Junior Preferred Stock;

           (ii)  declare or pay dividends on or make any other distributions  on
        any  shares of stock ranking on a parity (either as to dividends or upon
        liquidation,  dissolution  or  winding up)  with  the  Series  A  Junior
        Preferred  Stock, except dividends paid ratably on the Series  A  Junior
        Preferred  Stock  and all stock ranking on a parity with  the  Series  A
        Junior  Preferred Stock as to dividends on which dividends  are  payable
        or  in  arrears in proportion to the total amounts to which the  holders
        of all such shares are then entitled;

           (iii)  redeem  or  purchase  or otherwise acquire  for  consideration
        shares of any stock ranking on a parity (either as to dividends or  upon
        liquidation,  dissolution  or  winding up)  with  the  Series  A  Junior
        Preferred  Stock, provided that the Corporation may at any time  redeem,
        purchase  or  otherwise  acquire shares of  any  such  parity  stock  in
        exchange  for shares of any stock of the Corporation ranking junior  (as
        to  dividends and upon dissolution, liquidation or winding  up)  to  the
        Series A Junior Preferred Stock;

           (iv)  purchase or otherwise acquire for consideration any  shares  of
        Series  A  Junior Preferred Stock, except in accordance with a  purchase
        offer  made in writing or by publication (as determined by the Board  of
        Directors)  to all holders of such shares upon such terms as  the  Board
        of  Directors,  after  consideration of the respective  annual  dividend
        rates  and  other  relative  rights and preferences  of  the  respective
        series  and classes, shall determine in good faith will result  in  fair
        and equitable treatment among the respective series or classes.

        (B)  The  Corporation shall not permit any subsidiary of the Corporation
     to  purchase or otherwise acquire for consideration any shares of stock  of
     the  Corporation unless the Corporation could, under paragraph (A) of  this
     Section  4, purchase or otherwise acquire such shares at such time  and  in
     such manner.

     Section 5. Reacquired Shares. Any shares of Series A Junior Preferred Stock
  purchased  or  otherwise acquired by the Corporation in any manner  whatsoever
  shall  be  retired and cancelled promptly after the acquisition  thereof.  All
  such  shares  shall  upon  their cancellation become authorized  but  unissued
  shares  of  Preferred Stock and may be reissued as part of  a  new  series  of
  Preferred  Stock to be created by resolution or resolutions of  the  Board  of
  Directors,  subject to the conditions and restrictions on issuance  set  forth
  herein.

     Section 6. Liquidation, Dissolution or Winding Up.

         (A)   In  the  event  of  any  voluntary  or  involuntary  liquidation,
     dissolution or winding up of the Corporation, the holders of the  Series  A
     Junior  Preferred  Stock shall be entitled to receive the  greater  of  (a)
     $100  per  share,  plus  accrued dividends to  the  date  of  distribution,
     whether  or not earned or declared, or (b) an amount per share, subject  to
     the  provision for adjustment hereinafter set forth, equal to 100 times the
     aggregate  amount to be distributed per share to holders  of  Common  Stock
     (the  ''Series  A  Liquidation Preference''). In the event the  Corporation
     shall  at  any  time  after the Rights Declaration  Date  (i)  declare  any
     dividend  on Common Stock payable in shares of Common Stock, (ii) subdivide
     the  outstanding Common Stock or (iii) combine the outstanding Common Stock
     into  a  smaller  number of shares, then in each such case  the  amount  to
     which  holders  of shares of Series A Junior Preferred Stock were  entitled
     immediately  prior to such event pursuant to clause (b)  of  the  preceding
     sentence  shall  be adjusted by multiplying such amount by a  fraction  the
     numerator  of  which  is the number of shares of Common  Stock  outstanding
     immediately after such event and the denominator of which is the number  of
     shares  of  Common Stock that were outstanding immediately  prior  to  such
     event.

        (B)  In  the  event,  however,  that there  are  not  sufficient  assets
     available  to permit payment in full of the Series A Liquidation Preference
     and the liquidation preferences of all other series of preferred stock,  if
     any,  which rank on a parity with the Series A Junior Preferred Stock, then
     such  remaining assets shall be distributed ratably to the holders of  such
     parity shares in proportion to their respective liquidation preferences.

     Section 7. Consolidation, Merger, etc. In case the Corporation shall  enter
  into any consolidation, merger, combination or other transaction in which  the
  shares  of  Common  Stock are exchanged for or changed  into  other  stock  or
  securities, cash and/or any other property, then in any such case  the  shares
  of  Series  A  Junior  Preferred Stock shall at the  same  time  be  similarly
  exchanged  or  changed in an amount per share (subject to  the  provision  for
  adjustment hereinafter set forth) equal to 100 times the aggregate  amount  of
  stock,  securities, cash and/or any other property (payable in kind),  as  the
  case may be, into which or for which each share of Common Stock is changed  or
  exchanged.  In  the event the Corporation shall at any time after  the  Rights
  Declaration  Date (i) declare any dividend on Common Stock payable  in  shares
  of  Common  Stock,  (ii)  subdivide the outstanding  Common  Stock,  or  (iii)
  combine the outstanding Common Stock into a smaller number of shares, then  in
  each such case the amount set forth in the preceding sentence with respect  to
  the  exchange or change of shares of Series A Junior Preferred Stock shall  be
  adjusted  by multiplying such amount by a fraction the numerator of  which  is
  the  number of shares of Common Stock outstanding immediately after such event
  and  the  denominator of which is the number of shares of  Common  Stock  that
  were outstanding immediately prior to such event.

     Section 8. Optional Redemption.

        (A)  The  Corporation shall have the option to redeem the whole  or  any
     part  of  the  Series A Junior Preferred Stock at any time on at  least  30
     days  notice  in accordance with the provisions of paragraph  (B)  of  this
     Section  8  at  a redemption price equal to, subject to the  provision  for
     adjustment hereinafter set forth, 100 times the ''current per share  market
     price''  of  the Common Stock on the date of the mailing of the  notice  of
     redemption, together with unpaid accumulated dividends to the date of  such
     redemption.  In the event the Corporation shall at any time  after  October
     10,  1989  (i)  declare any dividend on Common Stock payable in  shares  of
     Common  Stock, (ii) subdivide the outstanding Common Stock or (iii) combine
     the  outstanding Common Stock into a smaller number of shares, then in each
     such  case  the  amount  to  which holders of shares  of  Series  A  Junior
     Preferred  Stock were otherwise entitled immediately prior  to  such  event
     under  the preceding sentence shall be adjusted by multiplying such  amount
     by  a  fraction  the numerator of which is the number of shares  of  Common
     Stock  outstanding  immediately after such event  and  the  denominator  of
     which  is  the  number  of  shares of Common Stock  that  were  outstanding
     immediately prior to such event. The ''current per share market price''  on
     any  date shall be deemed to be the average of the closing price per  share
     of  such Common Stock for the 10 consecutive Trading Days (as such term  is
     hereinafter defined) immediately prior to such date. The closing price  for
     each  day  shall be the last sale price, regular way, or, in case  no  such
     sale  takes  place on such day, the average of the closing  bid  and  asked
     prices   regular  way,  in  either  cases  as  reported  in  the  principal
     consolidated  transaction  reporting  system  with  respect  to  securities
     listed  or  admitted to trading on the New York Stock Exchange or,  if  the
     Common  Stock  is not listed or admitted to trading on the New  York  Stock
     Exchange,  as reported in the principal consolidated transaction  reporting
     system  with  respect to securities listed or admitted to  trading  on  the
     principal national securities exchange on which the Common Stock is  listed
     or  admitted  to trading or, if the Common Stock is not listed or  admitted
     to  trading on any national securities exchange, the last quoted price  or,
     if  not  so quoted the average of the high bid and low asked prices in  the
     over-the-counter  market,  as  reported  by  the  National  Association  of
     Securities Dealers, Inc. Automated Quotations System (''NASDAQ'')  or  such
     other  system then in use or, if on any such date the Common Stock  is  not
     quoted  by any such organization, the average of the closing bid and  asked
     prices  as furnished by a professional market maker making a market in  the
     Common  Stock selected by the Corporation. If on such date no  such  market
     maker  is making a market in the Common Stock, the fair value of the Common
     Stock  on  such date as determined in good faith by the Board of  Directors
     of  the  Corporation shall be used. The term ''Trading Day'' shall  mean  a
     day  on  which  the  principal national securities exchange  on  which  the
     Common  Stock is listed or admitted to trading is open for the  transaction
     of  business or, if the Common Stock is not listed or admitted  to  trading
     on   any  national  securities  exchange,  a  Monday,  Tuesday,  Wednesday,
     Thursday  or Friday on which banking institutions in the State of New  York
     are not authorized or obligated by law or executive order to close.

        (B)  Whenever  shares  of  Series A Junior Preferred  Stock  are  to  be
     redeemed,  the  Corporation shall mail a notice (''Notice of  Redemption'')
     by  first-class mail, postage prepaid, to each holder of record  of  shares
     of  Series  A  Junior Preferred Stock to be redeemed and  to  the  transfer
     agent  for  the  Series A Junior Preferred Stock. The Notice of  Redemption
     shall be addressed to the holder at the address of the holder appearing  on
     the  stock  transfer books of the Corporation maintained  by  the  transfer
     agent  for  the  Series A Junior Preferred Stock. The Notice of  Redemption
     shall  include a statement of (i) the redemption date, (ii) the  redemption
     price, (iii) the number of shares of Series A Junior Preferred Stock to  be
     redeemed,  (iv)  the place or places where shares of the  Series  A  Junior
     Preferred Stock are to be surrendered for payment of the redemption  price,
     (v)  that  the dividends on the shares to be redeemed will cease to  accrue
     on  such redemption date, and (vi) the provision under which redemption  is
     made.  No  defect  in  the Notice of Redemption or in the  mailing  thereof
     shall  affect  the  validity  of  the  redemption  proceedings,  except  as
     required  by law. From the date on which a Notice of Redemption shall  have
     been  given as aforesaid and the Corporation shall have deposited with  the
     transfer agent for the Series A Junior Preferred Stock a sum sufficient  to
     redeem the shares of Series A Junior Preferred Stock as to which Notice  of
     Redemption  has been given, with irrevocable instructions and authority  to
     pay  the redemption price to the holders thereof, or if no such deposit  is
     made,  then  upon  such date fixed for redemption (unless  the  Corporation
     shall  default  in making payment of the redemption price), all  rights  of
     the  holders  thereof as stockholders of the Corporation by reason  of  the
     ownership  of  such  shares (except their right to receive  the  redemption
     price  thereof, but without interest), shall terminate including,  but  not
     limited  to,  their right to receive dividends, and such  shares  shall  no
     longer  be  deemed  outstanding.  The  Corporation  shall  be  entitled  to
     receive,  from  time to time, from the transfer agent for Series  A  Junior
     Preferred Stock the interest, if any, on such monies deposited with it  and
     the  holders  of  any shares so redeemed shall have no claim  to  any  such
     interest.  In case the holder of any shares so called for redemption  shall
     not  claim  the redemption price for his shares within one year  after  the
     date  of  redemption, the transfer agent for the Series A Junior  Preferred
     Stock  shall,  upon  demand,  pay  over  to  the  Corporation  such  amount
     remaining  on  deposit  and the transfer agent  for  the  Series  A  Junior
     Preferred  Stock shall thereupon be relieved of all responsibility  to  the
     holders  of  such  shares and such holder of the shares  of  the  Series  A
     Junior  Preferred  Stock so called for redemption shall look  only  to  the
     Corporation for the payment thereof.

        (C)  In  the  event that fewer than all the outstanding  shares  of  the
     Series  A  Junior Preferred Stock are to be redeemed, the number of  shares
     to  be  redeemed  shall  be determined by the Board of  Directors  and  the
     shares  to  be redeemed shall be determined by lot or pro rata  as  may  be
     determined  by  the Board of Directors or by any other  method  as  may  be
     determined  by  the  Board  of  Directors in  its  sole  discretion  to  be
     equitable.

        (D)  If  the  Corporation shall be in default  in  the  payment  of  any
     dividends (including cumulative dividends, if applicable) on any shares  of
     Preferred  Stock  ranking, as to dividends, prior to the  Series  A  Junior
     Preferred  Stock,  then  no shares of the Series A Junior  Preferred  Stock
     shall  be  redeemed  and  the Corporation shall not purchase  or  otherwise
     acquire any shares of the Series A Junior Preferred Stock.

     Section 9. Ranking.

        (A)  The Series A Junior Preferred Stock shall rank junior to all  other
     series  of the Corporation's Preferred Stock as to the payment of dividends
     and  the  distribution of assets upon liquidation, dissolution  or  winding
     up, unless the terms of any such series shall provide otherwise.

        (B)  For purposes of this resolution, any stock of any class or  classes
     of the Corporation shall be deemed to rank:

           (i)  prior  to  the  shares of the Series A Junior  Preferred  Stock,
        either  as to dividends or upon liquidation, dissolution or winding  up,
        if  the  holders  of  such class or classes shall  be  entitled  to  the
        receipt  of  dividends  or  of amounts distributable  upon  dissolution,
        liquidation  or  winding  up of the Corporation,  whether  voluntary  or
        involuntary,  as  the  case may be, in preference  or  priority  to  the
        holders  of  shares of the Series A Junior Preferred Stock. Each  holder
        of  any  share of the Series A Junior Preferred Stock, by his acceptance
        thereof,  expressly covenants and agrees that the rights of the  holders
        of  any shares of any other series of Preferred Stock of the Corporation
        to   receive   dividends  or  amounts  distributable  upon  dissolution,
        liquidation  or  winding  up of the Corporation,  whether  voluntary  or
        involuntary,  shall  be and hereby are expressly  prior  to  his  rights
        unless  in  the  case  of any particular series of Preferred  Stock  the
        certificate  or  other  instrument  creating  or  evidencing  the   same
        expressly  provides that the rights of the holders of such series  shall
        not be prior to the shares of the Series A Junior Preferred Stock; and

           (ii)  on a parity with shares of the Series A Junior Preferred Stock,
        either  as to dividends or upon liquidation, whether or not the dividend
        rates,  dividend payment dates or redemption or liquidation  prices  per
        share  or  sinking fund provisions, if any, be different from  those  of
        the  Series A Junior Preferred Stock, if the holders of such stock shall
        be  entitled  to  the  receipt of dividends or of amounts  distributable
        upon  dissolution, liquidation or winding up of the Corporation, whether
        voluntary  or  involuntary, as the case may be, in proportion  to  their
        respective  dividend rates or liquidation prices, without preference  or
        priority,  one over the other, as between the holders of such stock  and
        the holders of shares of the Series A Junior Preferred Stock; and

           (iii) junior to shares of the Series A Junior Preferred Stock, either
        as  to dividends or upon liquidation, if such class or classes shall  be
        Common  Stock  or  if  the  holders of shares of  the  Series  A  Junior
        Preferred Stock shall be entitled to receipt of dividends or of  amounts
        distributable  upon  dissolution,  liquidation  or  winding  up  of  the
        Corporation, whether voluntary or involuntary, as the case  may  be,  in
        preference  or  priority  to the holders of  shares  of  such  class  or
        classes.

     Section 10. Amendment. Except as otherwise set forth in this Certificate of
  Designation,  Preferences  and Rights with respect  to  the  Series  A  Junior
  Preferred  Stock, holders of Series A Junior Preferred Stock  shall  not  have
  any  special  powers and their consent shall not be required  for  taking  any
  corporate action, provided, however, that:

        (A)  Unless  the vote or consent of the holders of a greater  number  of
     shares  shall  then be required by law, the consent of the  holders  of  at
     least  662/3%  of all of the shares of the Series A Junior Preferred  Stock
     at  the time outstanding, given in person or by proxy, either in writing or
     by  a  vote  at  a meeting called for the purpose at which the  holders  of
     shares  of  the  Series A Junior Preferred Stock shall vote together  as  a
     separate   class,  shall  be  necessary  for  authorizing,   effecting   or
     validating the amendment, alteration or repeal of any of the provisions  of
     the  Restated Certificate of Incorporation or of any certificate amendatory
     thereof  or supplemental thereto (including any Certificate of Designation,
     Preferences  and Rights or any similar document relating to any  series  of
     Preferred  Stock)  so  as to affect adversely the powers,  preferences,  or
     rights,  of  this  Series A Junior Preferred Stock.  The  increase  of  the
     authorized  amount  of the Preferred Stock, or the creation,  authorization
     or  issuance  of any shares of any other class of stock of the  Corporation
     ranking  prior  to or on a parity with the shares of the  Series  A  Junior
     Preferred   Stock   as   to   dividends  or  upon   liquidation,   or   the
     reclassification of any authorized or outstanding stock of the  Corporation
     into  any  such  prior or parity shares, or the creation, authorization  or
     issuance  of any obligation or security convertible into or evidencing  the
     right  to  purchase any such prior or parity shares shall not be deemed  to
     affect  adversely the powers, preferences or rights of the Series A  Junior
     Preferred Stock.

     Section  11.  Fractional Shares. Series A Junior  Preferred  Stock  may  be
  issued  in  fractions of a share which shall entitle the holder, in proportion
  to  such  holder's  fractional  shares, to  exercise  voting  rights,  receive
  dividends, participate in distributions and to have the benefit of  all  other
  rights of holders of Series A Junior Preferred Stock.


    6.50% Cumulative Convertible Preferred Stock
         (Without Par Value)

     1.  Designation.  This  resolution shall provide for  a  single  series  of
  Preferred  Stock,  the  designation  of  which  shall  be  ''6.50%  Cumulative
  Convertible  Preferred  Stock'', without par value  (hereinafter  called  this
  ''Series''), and the number of authorized shares constituting this  Series  is
  3,000,000. Shares of this Series shall have a stated value of $1.00 per  share
  (which  shall  also  be  the  stated capital of each  share).  The  number  of
  authorized shares of this Series may be reduced by further resolution  adopted
  by  the Board of Directors and by the filing of a certificate pursuant to  the
  provisions  of  the General Corporation Law of the State of  Delaware  stating
  that  such  reduction  has been so authorized, but the  number  of  authorized
  shares of this Series shall not be so increased.

     2. Dividends.

        (a)  The  holders of shares of this Series shall be entitled to  receive
     dividends  payable in cash at a rate of 6.50% per annum per  share  on  the
     initial  liquidation preference of $50.00 per share. Such  dividends  shall
     be  cumulative from the date of original issue of such shares, and shall be
     payable,  when, as and if declared by the Board of Directors, out of  funds
     legally  available  for such purpose, on the last calendar  day  of  March,
     June,  September  and  December of each year,  commencing  June  30,  1993,
     except that if such date is a Saturday, Sunday or legal holiday, then  such
     dividend  shall be payable on the first immediately preceding calendar  day
     which is not a Saturday, Sunday or legal holiday.

        (b)  Each dividend on shares of this Series shall be paid to the holders
     of  record of such shares as they appear on the stock transfer books of the
     Corporation  on  such  record date, not exceeding  30  days  preceding  the
     payment  date  thereof,  as  shall be fixed  by  the  Board  of  Directors.
     Dividends  in arrears for any past dividend period or any part thereof  may
     be  declared  and  paid  at  any time, without  reference  to  any  regular
     dividend payment date, to holders of record on such date, not exceeding  45
     days  preceding the payment date thereof, as may be fixed by the  Board  of
     Directors.

        (c)  Except  as hereinafter provided, no dividends shall be declared  or
     paid  or  set  apart  for  payment on the Preferred  Stock  of  any  series
     ranking,  as  to dividends, on a parity with or junior to this  Series  for
     any  period unless full cumulative dividends have been or contemporaneously
     are  declared  and paid on this Series for all past dividend periods.  When
     dividends  are  not  paid in full, as aforesaid, upon the  shares  of  this
     Series  and  any other Preferred Stock ranking on a parity as to  dividends
     with  this  Series, all dividends declared upon shares of this  Series  and
     any  other  Preferred Stock ranking on a parity as to dividends  with  this
     Series  shall be declared pro rata so that the amount of dividends declared
     per  share on this Series and such other Preferred Stock shall in all cases
     bear  to each other the same ratio that accrued dividends per share on  the
     shares  of  this Series and such other Preferred Stock bear to each  other.
     Holders  of  shares of this Series shall not be entitled to any  dividends,
     whether  payable  in cash, property or stock, in excess of full  cumulative
     dividends,  as  herein provided, on this Series. No  interest,  or  sum  of
     money  in  lieu  of interest, shall be payable in respect of  any  dividend
     payment or payments on this Series which may be in arrears.

        (d)  So  long as any shares of this Series are outstanding, no  dividend
     (other  than  a  dividend  in Common Stock or in any  other  stock  of  the
     Corporation  ranking  junior  to  this Series  as  to  dividends  and  upon
     liquidation  and other than as provided in Section 2(c)) shall be  declared
     or  paid  or set aside for payment or other distribution declared  or  made
     upon  the Common Stock or any other stock of the Corporation ranking junior
     to  or  on  a  parity with this Series as to dividends or upon liquidation,
     nor  shall any Common Stock nor any other stock of the Corporation  ranking
     junior  to  or  on  a  parity with this Series  as  to  dividends  or  upon
     liquidation   be  redeemed,  purchased  or  otherwise  acquired   for   any
     consideration  (or any moneys be paid to or made available  for  a  sinking
     fund  for  the  redemption  of  any  shares  of  any  such  stock)  by  the
     Corporation  (except  by  conversion into or  exchange  for  stock  of  the
     Corporation  ranking  junior  to  this Series  as  to  dividends  and  upon
     liquidation)  unless, in each case, the full cumulative  dividends  on  all
     outstanding   shares   of   this   Series   shall   have   been   paid   or
     contemporaneously are declared and paid for all past dividend periods.

        (e)  Dividends  payable on this Series for each full quarterly  dividend
     period  shall be computed by dividing the annual dividend rate by four  and
     multiplying  by  the initial liquidation preference of  $50.00  per  share.
     Dividends  payable on this Series for any period shorter or longer  than  a
     full  quarterly dividend period, including for the initial dividend period,
     shall be computed on the basis of a 360-day year of twelve 30-day months.

     3.  Optional  Redemption; Provision for U.S. Steel  Group  Special  Events;
     Related Provisions.

        (a)  Except as provided in Section 3(b), the shares of this Series shall
     not  be redeemable by the Corporation prior to April 1, 1996. On and  after
     April  1,  1996, shares of this Series may, subject to the satisfaction  of
     the  condition  set  forth in the last sentence of this  Section  3(a),  be
     redeemed, in whole at any time or in part from time to time, at the  option
     of  the  Corporation, out of funds legally available for such purpose,  for
     cash  in  an amount equal to the following redemption prices per  share  if
     redeemed  during  the twelve-month period beginning April  1  of  the  year
     indicated below, upon giving notice as provided below:



             Year           Redemption    Dollar
                              Price    Equivalent
                              (As a
                          percentage of Per Share
                             initial
                           liquidation
                           preference)
                                    
             1996             104.55%     $52.275
             1997             103.90       51.950
             1998             103.25       51.625
             1999             102.60       51.300
             2000             101.95       50.975
             2001             101.30       50.650
             2002             100.65       50.325
             2003 and
              thereafter      100.00       50.000



     and  thereafter at the initial liquidation preference of $50.00 per  share,
     plus,  in  each  case, an amount equal to all accrued and unpaid  dividends
     thereon to the date fixed for redemption. No shares of this Series  may  be
     redeemed  in accordance with this Section 3(a) if the Corporation shall  be
     advised  on  or  prior  to the related Redemption Date  by  either  Moody's
     Investors  Service,  Inc.  (''Moody's'') (provided  that  Moody's  is  then
     rating  the senior unsecured debt of the Corporation) or Standard &  Poor's
     Corporation  (''S&P'')  (provided  that  S&P  is  then  rating  the  senior
     unsecured debt of the Corporation) that such redemption would result in  an
     immediate  lowering by Moody's or S&P, as the case may be,  of  the  credit
     rating  on  the Corporation's senior unsecured debt from its then  existing
     level,  unless  the Corporation shall have received from  the  issuance  of
     common  stock of the Corporation, since the date which is two  years  prior
     to  the  related  Redemption Date, net proceeds in an aggregate  amount  at
     least  equal to the product of the initial liquidation preference of $50.00
     per share times the number of shares of this Series to be redeemed.

        (b)  (i) The shares of this Series shall be redeemed by the Corporation,
     in  whole, out of funds legally available for such purpose, for cash in  an
     amount  equal to the Redemption Price if any of the following  events  with
     respect  to  the  U.S.  Steel Group occur (such events,  collectively,  the
     ''U.S. Steel Group Special Events''):

           (A)  (1)  The Corporation exchanges all of the outstanding shares  of
        Steel  Stock  for all of the outstanding shares of common stock  of  the
        U.S.  Steel  Group  Subsidiary  (as provided  in  Section  2(b)(iii)  of
        Division  I  of  the  Certificate of Incorporation) (the  ''Steel  Group
        Subsidiary Exchange'') or (2) in the event of a Disposition  of  all  or
        substantially all of the properties and assets of the U.S. Steel  Group,
        the  Corporation  either  pays a dividend on  the  Steel  Stock  in,  or
        redeems  a number of shares of Steel Stock for, an amount equal  to  the
        Net  Proceeds of such Disposition (as provided in Section 2(b)(i)(A)  or
        Section  2(b)(i)(B), respectively, of Division I of the  Certificate  of
        Incorporation) (the ''Steel Group Disposition Dividend'' or the  ''Steel
        Group Disposition Redemption'', respectively); or

           (B) The Corporation pays a dividend on, or the Corporation or any  of
        its  Subsidiaries  consummates a tender offer  or  exchange  offer  for,
        shares  of Steel Stock and the aggregate amount of such dividend or  the
        consideration paid in such tender offer or exchange offer is  an  amount
        equal  to all or substantially all of the properties and assets  of  the
        U.S.  Steel  Group (the ''Steel Group Special Dividend'' or the  ''Steel
        Group  Tender  or  Exchange Offer'', respectively);  provided  that  the
        calculation of all or substantially all of the properties and assets  of
        the  U.S.  Steel Group shall be made without giving effect to any  money
        borrowed  by  the Corporation or any of its Subsidiaries  in  connection
        with  such dividend or tender offer or exchange offer, as the  case  may
        be.

     The  Redemption  Date  of shares of this Series pursuant  to  this  Section
     3(b)(i) shall be, if the applicable U.S. Steel Group Special Event  is  (I)
     the  Steel Group Subsidiary Exchange, the date of such exchange,  (II)  the
     Steel  Group Disposition Dividend or the Steel Group Special Dividend,  the
     date  such  dividend is paid, (III) the Steel Group Disposition Redemption,
     the  date  of  such redemption or (IV) the Steel Group Tender  or  Exchange
     Offer,  the  date  such  tender  offer or exchange  offer  is  consummated.
     Notwithstanding  anything  to  the  contrary  contained  in  this   Section
     3(b)(i),  any  redemption  pursuant  to  this  Section  3(b)(i)  shall   be
     conditioned  upon the actual exchange of Steel Stock for shares  of  common
     stock  of  the  U.S.  Steel Group Subsidiary, payment of  the  Steel  Group
     Disposition  Dividend  or the amount due as a result  of  the  Steel  Group
     Disposition  Redemption  (in  each case in the  required  kind  of  capital
     stock, cash, securities and/or other property), payment of the Steel  Group
     Special  Dividend or the consummation of the Steel Group Tender or Exchange
     Offer, as the case may be.

        (ii) The shares of this Series shall be redeemed by the Corporation,  in
      whole,  out  of funds legally available for such purpose, for cash  in  an
      amount  equal to the Redemption Price if following the Disposition of  all
      or  substantially  all  of the properties and assets  of  the  U.S.  Steel
      Group,  the Corporation exchanges all of the outstanding shares  of  Steel
      Stock for Marathon Stock (as provided in Section 2(b)(i)(C) of Division  I
      of  the Certificate of Incorporation) and, at any time subsequent to  such
      exchange,  any of the following events with respect to the Marathon  Group
      occur (such events, collectively, the ''Marathon Group Special Events''):

           (A)  The  Corporation  exchanges all of  the  outstanding  shares  of
        Marathon Stock for all of the outstanding shares of common stock of  the
        Marathon Group Subsidiary (as provided in Section 2(a)(i) of Division  I
        of  the  Certificate of Incorporation) (the ''Marathon Group  Subsidiary
        Exchange''); or

           (B) The Corporation pays a dividend on, or the Corporation or any  of
        its  Subsidiaries  consummates a tender offer  or  exchange  offer  for,
        shares  of  Marathon Stock and the aggregate amount of such dividend  or
        the  consideration  paid in such tender offer or exchange  offer  is  an
        amount  equal to all or substantially all of the properties  and  assets
        of  the  Marathon Group (the ''Marathon Group Special Dividend'' or  the
        ''Marathon  Group  Tender  or Exchange Offer'', respectively);  provided
        that  the calculation of all or substantially all of the properties  and
        assets of the Marathon Group shall be made without giving effect to  any
        money  borrowed  by  the  Corporation or  any  of  its  Subsidiaries  in
        connection with such dividend or tender offer or exchange offer, as  the
        case  may  be;  provided, further, that, at the time of the  payment  of
        such  dividend on, or the consummation of such tender or exchange  offer
        for,  Marathon Stock, there is another class of common stock, other than
        Marathon Stock, of the Corporation then outstanding.

     The  Redemption  Date  of shares of this Series pursuant  to  this  Section
     3(b)(ii)  shall be, if the applicable Marathon Group Special Event  is  (I)
     the  Marathon  Group Subsidiary Exchange, the date of such  exchange,  (II)
     the  Marathon  Group Special Dividend, the date such dividend  is  paid  or
     (III)  the  Marathon Group Tender or Exchange Offer, the date  such  tender
     offer  or  exchange offer is consummated. Notwithstanding anything  to  the
     contrary  contained  in this Section 3(b)(ii), any redemption  pursuant  to
     this  Section  3(b)(ii) shall be conditioned upon the  actual  exchange  of
     Marathon   Stock  for  shares  of  common  stock  of  the  Marathon   Group
     Subsidiary,  payment  of  the  Marathon  Group  Special  Dividend  or   the
     consummation of the Marathon Group Tender or Exchange Offer,  as  the  case
     may be.

        (c)  The  following general redemption provisions shall  apply,  as  the
     context  requires, to any redemption of any shares of this Series  pursuant
     to this Section 3:

           (i)  In the event that fewer than all the outstanding shares of  this
        Series are to be redeemed, the number of shares to be redeemed shall  be
        determined  by  the  Board of Directors and the shares  to  be  redeemed
        shall  be  determined  by lot or pro rata as may be  determined  by  the
        Board  of Directors or by any other method as may be determined  by  the
        Board  of  Directors  in its sole discretion to be  equitable,  provided
        that  the  Corporation may redeem any number of shares  of  this  Series
        owned  by holders whose aggregate holdings of such shares do not  exceed
        100 as may be specified by the Corporation.

           (ii)  In the event the Corporation shall redeem shares of this Series
        pursuant  to this Section 3, notice of such redemption shall  be  given,
        (x)  if  such  redemption  is  a result of the  Steel  Group  Tender  or
        Exchange  Offer or the Marathon Group Tender or Exchange Offer,  on  the
        date  of the public announcement of such tender offer or exchange  offer
        by  the  Corporation or any of its Subsidiaries, but in  any  event  not
        less  than  30  days prior to such redemption, and on the  date  of  the
        public announcement of any extension thereof, (y) if such redemption  is
        a  result  of  the Steel Group Disposition Dividend or the  Steel  Group
        Disposition  Redemption, on a date not less than 45 days  prior  to  the
        date  selected  by  the  Board of Directors  for  the  payment  of  such
        dividend  or  such redemption and (z) otherwise, on a date at  least  30
        days  but  not  more  than  60 days prior to the  date  fixed  for  such
        redemption  by  the Board of Directors, in each case to each  holder  of
        record  of  the shares of this Series to be redeemed. Such notice  shall
        be  given by first class mail, postage prepaid, at such holder's address
        as  the  same  appears on the stock transfer books of  the  Corporation.
        Neither  the  failure  to  mail, to any particular  holder,  any  notice
        required  by  this  Section 3(c)(ii) nor any defect therein  or  in  the
        mailing  thereof,  shall affect the sufficiency of  the  notice  or  the
        validity  of  the proceedings for redemption with respect to  any  other
        holder. Any notice which was mailed in the manner herein provided  shall
        be  conclusively  presumed to have been duly given on  the  date  mailed
        whether  or  not the holder receives the notice. Each such notice  shall
        state,  as  appropriate:  (A) the Redemption Date;  (B)  the  number  of
        shares  of this Series to be redeemed and, if fewer than all the  shares
        held by such holder are to be redeemed, the number of such shares to  be
        redeemed  from  such  holder; (C) the Redemption Price  to  be  paid  in
        respect  of  the redemption; (D) the place or places where  certificates
        for  such shares are to be surrendered for the payment of the Redemption
        Price;  (E)  the  then current Conversion Price and, if any  event  then
        known  to the Corporation will result in an adjustment to the Conversion
        Price  on  or  prior  to the Redemption Date, such  adjusted  Conversion
        Price  and the date of such adjustment; (F) if such redemption of shares
        of  this Series is the result of a U.S. Steel Group Special Event  or  a
        Marathon  Group Special Event, that such redemption is conditioned  upon
        the  occurrence  of  the applicable U.S. Steel Group  Special  Event  or
        Marathon Group Special Event and if that U.S. Steel Group Special  Event
        is  the  Steel Group Disposition Dividend or the Steel Group Disposition
        Redemption,  the  last date on which the shares of this  Series  may  be
        converted  into  shares  of  Steel Stock, determined  as  set  forth  in
        Section 4(a); and (G) that dividends on the shares of this Series to  be
        redeemed shall cease to accrue on the Redemption Date, provided that  if
        such  redemption of shares of this Series is the result of a U.S.  Steel
        Group  Special  Event or a Marathon Group Special Event, the  conditions
        to such redemption shall have been satisfied.

           (iii) Notice having been given as provided in Section 3(c)(ii),  from
        and  after  the  Redemption Date (unless default shall be  made  by  the
        Corporation in providing an adequate amount of money for the payment  of
        the  Redemption Price necessary to effect such redemption in  accordance
        with  the terms hereof) (A) except if the redemption is the result of  a
        U.S.  Steel  Group Special Event or a Marathon Group Special  Event  and
        the  conditions  to  such  redemption shall  not  have  been  satisfied,
        dividends  on  the shares of this Series so called for redemption  shall
        cease  to  accrue,  (B)  such shares shall no longer  be  deemed  to  be
        outstanding  and  (C) all rights of the holders thereof  as  holders  of
        shares of this Series shall cease (except the right to receive from  the
        Corporation  the  Redemption  Price,  without  interest  thereon,   upon
        surrender  and  endorsement of their certificates).  Upon  surrender  in
        accordance  with  said  notice of the certificates  for  any  shares  so
        redeemed  (properly  endorsed  or  assigned  for  transfer,  unless  the
        Corporation  shall  waive such requirement), such  shares  shall  be  so
        redeemed by the Corporation.

           (iv)  The  Corporation's obligation to provide an adequate amount  of
        money  for  the payment of the Redemption Price necessary to effect  any
        redemption  in accordance with this Section 3 shall be deemed  fulfilled
        if,  on or before the applicable Redemption Date, the Corporation  shall
        deposit  with a bank or trust company that has an office in the  Borough
        of  Manhattan, City of New York, and that has, or is an affiliate  of  a
        bank  or  trust  company that has, a capital and  surplus  of  at  least
        $50,000,000,  an  amount  of  money adequate  for  the  payment  of  the
        aggregate  Redemption Price necessary for such redemption in  accordance
        with  the  terms  hereof, in trust, with irrevocable  instructions  that
        such money be applied to the redemption of the shares of this Series  so
        called  for  redemption.  If such redemption  is  conditioned  upon  the
        payment  of  the  Steel Group Disposition Dividend  or  payment  of  the
        amount  due  as a result of the Steel Group Disposition Redemption,  the
        Corporation   shall  deposit  such  moneys  and  give  such  irrevocable
        instructions  in respect of such redemption, subject to the  payment  of
        such Steel Group Disposition Dividend or payment of the amount due as  a
        result  of such Steel Group Disposition Redemption, not later  than  the
        30th  day  prior  to the date selected by the Board for the  payment  of
        such  dividend on, or the redemption of, Steel Stock, but in  any  event
        prior  to  the  date  the Corporation declares such  dividend  or  gives
        notice  of  such  redemption,  each in  accordance  with  Section  2  of
        Division  I  of  the  Certificate of Incorporation.  No  interest  shall
        accrue  for  the benefit of the holders of shares of this Series  to  be
        redeemed  on any money so payable by the Corporation in respect  of  any
        redemption.  Subject to applicable escheat laws, any money unclaimed  at
        the  end  of two years from the related Redemption Date shall revert  to
        the  general funds of the Corporation, after which reversion the holders
        of  such  shares so called for redemption shall look only to the general
        funds  of  the Corporation for the payment of such money. In case  fewer
        than  all  the shares of this Series represented by any such certificate
        are  redeemed,  a  new  certificate shall  be  issued  representing  the
        unredeemed shares without cost to the holder thereof.

           (v)  Any  shares  of this Series which shall at any  time  have  been
        redeemed shall, upon the taking of any action required by law, have  the
        status  of  authorized but unissued shares of Preferred  Stock,  without
        designation  as to series until such shares are once more designated  as
        part of a particular series by the Board of Directors.

           (vi)  Notwithstanding the foregoing provisions  of  this  Section  3,
        unless  the full cumulative dividends on all outstanding shares of  this
        Series  shall have been paid or contemporaneously are declared and  paid
        for  all  past  dividend  periods, no shares of  this  Series  shall  be
        redeemed   unless   all   outstanding  shares   of   this   Series   are
        simultaneously  redeemed,  and the Corporation  shall  not  purchase  or
        otherwise  acquire  any shares of this Series; provided,  however,  that
        the  foregoing shall not prevent the purchase or acquisition  of  shares
        of  this  Series pursuant to a purchase or exchange offer  made  on  the
        same terms to holders of all outstanding shares of this Series.

     4.  Conversion or Exchange. Holders of shares of this Series shall have the
  right  to convert all or a portion of such shares into shares of Steel  Stock,
  as follows:

        (a)  Subject to and upon compliance with the provisions of this  Section
     4,  a  holder  of  shares  of this Series shall have  the  right,  at  such
     holder's  option, at any time, to convert such shares into  the  number  of
     fully  paid  and nonassessable shares of Steel Stock equal to the  quotient
     of  (i)  the  product of the initial liquidation preference for  shares  of
     this  Series of $50.00 per share for such shares times the number of shares
     of  this  Series to be converted, divided by (ii) the Conversion Price  (as
     in  effect on the date provided for in the last paragraph of Section  4(b))
     by  surrendering the certificates representing such shares to be converted,
     such  surrender to be made in the manner provided in accordance  with  this
     Section 4; provided that the right to convert shares of this Series  called
     for  redemption  pursuant  to Section 3 shall terminate  at  the  close  of
     business  on  the  related Redemption Date, unless  the  Corporation  shall
     default in making payment of any moneys payable upon such redemption  under
     Section  3 or, if the redemption of shares of this Series is the result  of
     a  Steel  Group  Special  Event  or a Marathon  Group  Special  Event,  the
     conditions  to  such  redemption  shall  not  have  been  satisfied;   and,
     provided,  further,  that  if  the  Corporation  has  given  notice  of   a
     redemption  pursuant to Section 3(c) which is conditioned on the occurrence
     of  the  Steel  Group Disposition Dividend or the Steel  Group  Disposition
     Redemption,  the right to convert shares of this Series shall terminate  on
     the  31st day prior to the date selected by the Board of Directors for such
     redemption.  Any  holder of any share or shares of  this  Series  may  only
     convert  whole  shares  of  this Series and the Corporation  shall  not  be
     obligated to issue any fractional shares of this Series.

        (b)  In order to exercise the conversion right, the holder of any shares
     of   this   Series   to  be  converted  shall  surrender  the   certificate
     representing  such shares, duly endorsed or assigned to the Corporation  or
     in  blank,  at  the  office of the Transfer Agent, accompanied  by  written
     notice  to  the Corporation that the holder thereof elects to convert  such
     shares  or  a  specified  portion thereof. Unless the  shares  issuable  on
     conversion  are  to be issued in the same name as the name  in  which  such
     shares   of  this  Series  are  registered,  any  shares  surrendered   for
     conversion  shall  be  accompanied  by instruments  of  transfer,  in  form
     satisfactory  to  the  Corporation, duly executed by  the  holder  or  such
     holder's  duly  authorized attorney and an amount  sufficient  to  pay  any
     transfer  or  similar  tax  (or  evidence reasonably  satisfactory  to  the
     Corporation demonstrating that such taxes have been paid).

        Holders  of shares of this Series at the close of business on  a  record
     date  for determining stockholders entitled to receive a dividend shall  be
     entitled   to  receive  the  dividend  payable  on  such  shares   on   the
     corresponding  dividend payment date (except that holders of shares  called
     for  redemption  on  a  Redemption Date between such record  date  and  the
     dividend  payment  date shall not be entitled to receive such  dividend  on
     such   dividend  payment  date)  notwithstanding  the  conversion   thereof
     following  such  dividend record date and prior to  such  dividend  payment
     date. However, shares of this Series surrendered for conversion during  the
     period  between the close of business on any dividend record date  and  the
     opening  of  business  on the corresponding dividend payment  date  (except
     shares called for redemption on a Redemption Date during such period)  must
     be  accompanied  by payment of an amount equal to the dividend  payable  on
     such  shares  on  such dividend payment date. A holder of  shares  of  this
     Series  on  a  dividend record date who (or whose transferee)  tenders  any
     such  shares  for  conversion into shares of  Steel  Stock  on  a  dividend
     payment  date will receive the dividend payable by the Corporation on  such
     shares  of  this  Series on such date, and the converting holder  need  not
     include  payment  of  the amount of such dividend upon  surrender  of  such
     shares  for  conversion. Except as provided above,  the  Corporation  shall
     make  no  payment  or allowance for unpaid dividends,  whether  or  not  in
     arrears, on converted shares or for dividends on the shares of Steel  Stock
     issued upon such conversion.

        As  promptly  as  practicable after the surrender  of  certificates  for
     shares  of this Series as aforesaid, the Corporation shall issue and  shall
     deliver  at such office to such holder, or on such holder's written  order,
     a  certificate or certificates for the number of full shares of Steel Stock
     issuable  upon  the  conversion  of such  shares  in  accordance  with  the
     provisions of this Section 4, and any fractional interest in respect  of  a
     share  of  Steel  Stock arising upon such conversion shall  be  settled  as
     provided in Section 4(c).

        Each  conversion shall be deemed to have been effected immediately prior
     to  the  close of business on the date on which the certificates for shares
     of  this Series shall have been surrendered and the notice referred  to  in
     the  third  preceding paragraph (and, if applicable, payment of  an  amount
     equal  to  the dividend payable on such shares as described in  the  second
     preceding  paragraph)  received by the Corporation as  aforesaid,  and  the
     person  or  persons in whose name or names any certificate or  certificates
     for  shares of Steel Stock shall be issuable upon such conversion shall  be
     deemed  to  have  become  the holder or holders of  record  of  the  shares
     represented thereby at such time on such date and such conversion shall  be
     at the Conversion Price in effect at such time on such date.

        (c)  No  fractional shares or scrip representing fractions of shares  of
     Steel  Stock or any other common stock of the Corporation shall  be  issued
     upon  conversion  of any share of this Series. Instead  of  any  fractional
     interest  in a share of Steel Stock or such other common stock  that  would
     otherwise  be  deliverable upon the conversion of a share of  this  Series,
     the  Corporation shall pay to the holder of such share an  amount  in  cash
     based  upon the Closing Price of Steel Stock or such other common stock  on
     the  Trading Day immediately preceding the date of conversion. If more than
     one  share  shall  be surrendered for conversion at one time  by  the  same
     holder,  the  number  of full shares of Steel Stock or  such  other  common
     stock  issuable upon conversion thereof shall be computed on the  basis  of
     the aggregate number of shares of this Series so surrendered.

        (d) The Conversion Price per share of Steel Stock shall be adjusted from
     time to time as follows:

           (i)  If the Corporation shall after the date on which shares of  this
        Series  are  initially issued (A) pay a dividend or make a  distribution
        on  any  class  of  its  capital stock in shares  of  Steel  Stock,  (B)
        subdivide  the outstanding Steel Stock into a greater number  of  shares
        or  (C)  combine  the outstanding Steel Stock into a smaller  number  of
        shares,  then the Conversion Price in effect at the opening of  business
        on  the  day  next  following the date fixed for  the  determination  of
        stockholders  entitled to receive such dividend or  distribution  or  at
        the  opening of business on the day next following the day on which such
        subdivision or combination becomes effective, as the case may be,  shall
        be  adjusted  so that the holder of any share of this Series  thereafter
        surrendered  for conversion shall be entitled to receive the  number  of
        shares  of  Steel Stock that such holder would have owned or  have  been
        entitled  to receive after the happening of any of the events  described
        above  had  such share been converted immediately prior  to  the  record
        date in the case of a dividend or distribution or the effective date  in
        the  case  of a subdivision or combination. An adjustment made  pursuant
        to  this  Section 4(d)(i) shall become effective immediately  after  the
        opening  of  business on the day next following the record date  (except
        as  provided  in Section 4(m)) in the case of a dividend or distribution
        and shall become effective immediately after the opening of business  on
        the  day  next following the effective date in the case of a subdivision
        or combination.

           (ii) If the Corporation shall issue after the date on which shares of
        this  Series  are  initially issued rights or warrants (other  than  any
        rights  or  warrants  (including  the Rights)  referred  to  in  Section
        4(d)(iii)  below) to all holders of Steel Stock entitling  them  (for  a
        period  expiring  within 45 days after the record date mentioned  below)
        to  subscribe for or purchase Steel Stock at a price per share less than
        the  Current  Market Price per share of Steel Stock on the  record  date
        for  the  determination of stockholders entitled to receive such  rights
        or  warrants,  then  the Conversion Price in effect at  the  opening  of
        business  on  the day next following such record date shall be  adjusted
        to  equal  the price determined by multiplying (I) the Conversion  Price
        in  effect immediately prior to the opening of business on the day  next
        following the date fixed for such determination by (II) a fraction,  the
        numerator  of  which  shall be the sum of (A) the number  of  shares  of
        Steel  Stock outstanding on the close of business on the date fixed  for
        such  determination  and  (B) the number of shares  that  the  aggregate
        proceeds  to  the  Corporation  from the  exercise  of  such  rights  or
        warrants  for  Steel Stock would purchase at such Current Market  Price,
        and  the  denominator of which shall be the sum of  (A)  the  number  of
        shares  of Steel Stock outstanding on the close of business on the  date
        fixed for such determination and (B) the number of additional shares  of
        Steel  Stock  offered  for  subscription or purchase  pursuant  to  such
        rights  or  warrants. Such adjustment shall become effective immediately
        after  the  opening  of business on the day next following  such  record
        date  (except as provided in Section 4(m)). In determining  whether  any
        rights  or warrants entitle the holders of Steel Stock to subscribe  for
        or  purchase shares of Steel Stock at less than the Current Market Price
        thereof,  there  shall be taken into account any consideration  received
        by  the  Corporation upon issuance and upon exercise of such  rights  or
        warrants,  the value of such consideration, if other than  cash,  to  be
        determined by the Board of Directors.

           (iii) If the Corporation shall distribute to all holders of the Steel
        Stock  any  shares  of  capital stock (other than common  stock  of  the
        Corporation),  evidences of indebtedness, cash or other  assets  of  the
        Corporation  (including securities, but excluding (w)  any  dividend  or
        distribution referred to in Section 4(d)(i), (x) any rights or  warrants
        referred  to in Section 4(d)(ii) or in the second or third paragraph  of
        this   Section   4(d)(iii),  (y)  any  dividend  or  distribution   paid
        exclusively  in  cash or (z) any stocks, securities  or  other  property
        received as a result of a transaction referred to in Section 4(f))  (any
        of   the  foregoing  being  hereinafter  referred  to  in  this  Section
        4(d)(iii)  as the ''Securities''), then in each such case the Conversion
        Price  shall be adjusted so that it shall equal the price determined  by
        multiplying (I) the Conversion Price in effect immediately prior to  the
        close   of  business  on  the  date  fixed  for  the  determination   of
        stockholders entitled to receive such distribution by (II)  a  fraction,
        the  numerator of which shall be the Current Market Price per  share  of
        the  Steel  Stock on the record date mentioned below less the then  fair
        market  value (as determined by the Board of Directors) of  the  portion
        of  the  Securities so distributed to one share of Steel Stock, and  the
        denominator of which shall be the Current Market Price per share of  the
        Steel  Stock  on the record date mentioned below. Such adjustment  shall
        become effective immediately at the opening of business on the day  next
        following   the  record  date  for  the  determination  of  stockholders
        entitled  to  receive such distribution (except as provided  in  Section
        4(m)).

        With  respect to the Amended and Restated Rights Agreement, dated as  of
     October  1, 1992 (as amended or otherwise modified from time to  time,  the
     ''Restated  Rights Agreement''), between the Corporation and  Mellon  Bank,
     N.A.  (terms used in this paragraph and not otherwise defined herein having
     the  meanings  set forth in the Restated Rights Agreement), the  Conversion
     Price  will  be  adjusted  only when the Rights issuable  pursuant  thereto
     become  exercisable after the Corporation's right of redemption  thereunder
     has  expired.  Subject to the foregoing, upon the later  to  occur  of  the
     Distribution Date and a Section 11(a)(ii) Event (the ''Adjustment  Date''),
     the  Conversion  Price  in  effect  at  the  opening  of  business  on  the
     Adjustment  Date  shall  be  adjusted to  equal  the  price  determined  by
     multiplying  such  Conversion Price by a fraction the  numerator  of  which
     shall be equal to the Current Market Price per share of the Steel Stock  on
     the  Trading  Day immediately prior to the Adjustment Date less  an  amount
     equal  to  the  quotient  of (x) the aggregate fair  market  value  on  the
     Adjustment  Date (as determined by the Board of Directors)  of  the  Rights
     distributed under the Restated Rights Agreement divided by (y)  the  number
     of  shares  of Steel Stock outstanding on such day prior to the  Adjustment
     Date  and  the  denominator of which shall be equal to such Current  Market
     Price  per share of the Steel Stock. Such adjustment shall become effective
     immediately  after the opening of business on the day next  following  such
     Adjustment Date.

        In  case  the  Corporation shall (other than pursuant  to  the  Restated
     Rights  Agreement)  distribute rights or warrants to purchase  Steel  Stock
     pro rata to all holders of Steel Stock which rights or warrants are not  at
     such  time  immediately exercisable but, upon the occurrence of a specified
     event  or  events  (''Exercise Trigger Date'') will become exercisable  and
     once  they  become exercisable will entitle, or upon the occurrence  of  an
     additional  specified  event  or  events  (''Price  Trigger  Date'')   will
     entitle,  the holder thereof to purchase Steel Stock at a price  per  share
     of  Steel  Stock less than the Current Market Price of the Steel  Stock  on
     the  Trading Day next succeeding the later of the Exercise Trigger Date  or
     the  Price Trigger Date (''Adjustment Trigger Date'') and there shall  have
     occurred such Adjustment Trigger Date, thus permitting the holders of  such
     rights  or  warrants irrevocably to exercise any exchange, subscription  or
     purchase  rights conferred by such rights or warrants at a price per  share
     of  Steel  Stock  less than such Current Market Price, then the  Conversion
     Price  in effect at the opening of business on the Adjustment Trigger  Date
     shall  be  adjusted  by multiplying (I) such Conversion  Price  by  (II)  a
     fraction,  the  numerator of which shall be equal  to  the  Current  Market
     Price per share of the Steel Stock on the Trading Day immediately prior  to
     the  Adjustment  Trigger Date less an amount equal to the quotient  of  (x)
     the  aggregate  fair  market value on the Adjustment Trigger  Date  of  the
     rights  or  warrants  so  distributed  (as  determined  by  the  Board   of
     Directors)  divided by (y) the number of shares of Steel Stock  outstanding
     on  such  day  prior to the Adjustment Trigger Date and the denominator  of
     which  shall be equal to such Current Market Price per share of  the  Steel
     Stock.  Such  adjustment  shall  become  effective  immediately  after  the
     opening  of  business  on  the day next following such  Adjustment  Trigger
     Date.

           (iv) If the Corporation shall, by dividend or otherwise, at any  time
        distribute  to  all  holders  of the Steel  Stock  cash  (excluding  any
        regular  quarterly dividend payable solely in cash,  any  cash  that  is
        distributed  as  part  of a distribution requiring  a  Conversion  Price
        adjustment  pursuant to Section 4(d)(iii) and cash that  is  distributed
        in  a  merger  or  consolidation to which Section 4(f)  applies)  in  an
        aggregate  amount that, together with (A) the aggregate  amount  of  any
        other  distributions to all holders of the Steel Stock made  exclusively
        in  cash  (to which this Section 4(d)(iv) would otherwise apply)  within
        the 12 months preceding the date of payment of such distribution and  in
        respect  of which no Conversion Price adjustment has been made  and  (B)
        all  Excess  Purchase  Payments  in respect  of  each  tender  offer  or
        exchange  offer  or other negotiated purchase for Steel Stock  concluded
        by  the  Corporation  or any of its Subsidiaries within  the  12  months
        preceding  the  date of payment of such distribution and in  respect  of
        which  no  Conversion Price adjustment has been made, exceeds an  amount
        equal to 121/2% of the product of the Current Market Price per share  of
        Steel  Stock  on  the date fixed for determination of holders  of  Steel
        Stock  entitled to receive such distribution times the number of  shares
        of  Steel  Stock  outstanding on such date, then  the  Conversion  Price
        shall  be  adjusted  so  that it shall equal  the  price  determined  by
        multiplying  (I)  such Conversion Price in effect immediately  prior  to
        the  Conversion  Price adjustment contemplated by this Section  4(d)(iv)
        by  (II)  a fraction the numerator of which shall be the Current  Market
        Price  per  share of the Steel Stock on the date fixed for determination
        of  holders  of  Steel Stock entitled to receive such distribution  less
        the  combined amount of such cash and such Excess Purchase  Payments  so
        distributed  applicable to one share of Steel Stock and the  denominator
        of  which  shall  be such Current Market Price per share  of  the  Steel
        Stock  on  such  date  of  determination. Such adjustment  shall  become
        effective immediately prior to the opening of business on the  day  next
        following the date fixed for such determination.

           (v)  In  case  a  tender offer or exchange offer or other  negotiated
        purchase made by the Corporation or any of its Subsidiaries for  all  or
        any  portion  of the Steel Stock shall be consummated, if the  aggregate
        amount  of  any Excess Purchase Payment, together with (A) the aggregate
        amount  of  any  distributions made to all holders of Steel  Stock  made
        exclusively  in  cash (excluding any regular quarterly dividend  payable
        solely  in  cash, any cash that is distributed as part of a distribution
        requiring  a  Conversion Price adjustment pursuant to Section  4(d)(iii)
        and  cash  that  is  distributed in a merger or consolidation  to  which
        Section  4(f)  applies) within the 12 months preceding the  consummation
        of  such  tender or exchange offer or other negotiated purchase  and  in
        respect  of which no Conversion Price adjustment has been made, and  (B)
        all  other  Excess  Purchase  Payments in  respect  of  each  tender  or
        exchange  offer  or other negotiated purchase for Steel Stock  concluded
        by  the  Corporation  or any of its Subsidiaries within  the  12  months
        preceding  the  consummation of such tender or exchange offer  or  other
        negotiated  purchase  and  in  respect  of  which  no  Conversion  Price
        adjustment  has  been made, exceeds an amount equal  to  121/2%  of  the
        product  of  the Current Market Price per share of Steel  Stock  on  the
        consummation  date of such tender or exchange offer or other  negotiated
        purchase  (any  such date, the ''Purchase Date'') times  the  number  of
        shares of Steel Stock outstanding (including any tendered, exchanged  or
        purchased  shares)  on  such Purchase Date, then  the  Conversion  Price
        shall  be  adjusted  so  that it shall equal  the  price  determined  by
        multiplying  (I)  such Conversion Price in effect immediately  prior  to
        such  Purchase Date by (II) a fraction, the numerator of which shall  be
        the  Current Market Price per share of the Steel Stock on such  Purchase
        Date  less the combined amount of Excess Purchase Payments and such cash
        so   distributed  applicable  to  one  share  of  Steel  Stock  and  the
        denominator  of which shall be such Current Market Price  per  share  on
        such  Purchase Date. Such adjustment shall become effective  immediately
        prior  to  the  opening  of  business on the  day  next  following  such
        Purchase Date.

           (vi)  The  Corporation  from time to time may reduce  the  Conversion
        Price  by  any  amount for any period of at least 20 business  days  (or
        such  other period as may then be required by applicable law),  provided
        that  the  Board of Directors shall have determined that such  reduction
        is  in  the  best  interests of the Corporation.  No  reduction  in  the
        Conversion  Price  pursuant  to  this  Section  4(d)(vi)  shall   become
        effective  unless the Corporation shall have mailed a notice,  at  least
        15  days  prior  to  the date on which such reduction  is  scheduled  to
        become  effective, to each holder of shares of this Series. Such  notice
        shall  be  given by first class mail, postage prepaid, at such  holder's
        address  as  the  same  appears  on the  stock  transfer  books  of  the
        Corporation. Such notice shall state the amount per share by  which  the
        Conversion  Price  will  be  reduced  and  the  period  for  which  such
        reduction will be in effect.

           (vii)  The  Corporation may make such reductions  in  the  Conversion
        Price,  in  addition to those required by Sections 4(d)(i) through  (v),
        as  the Board determines to be necessary in order that any event treated
        for  Federal income tax purposes as a dividend of stock or stock  rights
        will  not be taxable to the recipients; provided that any such reduction
        shall  not  be  effective until written evidence of the  action  of  the
        Board  authorizing such reduction shall be filed with the  Secretary  of
        the  Corporation and notice thereof shall have been given by first class
        mail,  postage prepaid, to each holder of shares of this Series at  such
        holder's address as the same appears on the stock transfer books of  the
        Corporation.

        (e)  No adjustment in the Conversion Price shall be required unless such
     adjustment would require a cumulative increase or decrease of at  least  1%
     in  such  price; provided, however, that any adjustments that by reason  of
     this Section 4(e) are not required to be made shall be carried forward  and
     taken  into account in any subsequent adjustment until made; and  provided,
     further, that any adjustment shall be required and made in accordance  with
     the  provisions of this Section 4 (other than this Section 4(e)) not  later
     than  such time as may be required in order to preserve the tax-free nature
     of  a  distribution to the holders of shares of Steel Stock  or  any  other
     common   stock   into  which  shares  of  this  Series   are   convertible.
     Notwithstanding  any other provisions of this Section  4,  the  Corporation
     shall  not  be  required  to make any adjustment of  any  Conversion  Price
     established  hereunder for the issuance of any shares of  common  stock  of
     the  Corporation (including Steel Stock) pursuant to any plan providing for
     the  reinvestment  of dividends or interest payable on  securities  of  the
     Corporation and the investment of additional optional amounts in shares  of
     such  common stock under such plan. All calculations under this  Section  4
     shall  be  made to the nearest 1/100 of a cent (with $.00005 being  rounded
     upward)  or  to  the nearest 1/10,000 of a share (with .00005  of  a  share
     being rounded upward), as the case may be.

        (f)  If  the Corporation shall be a party to any transaction  (including
     without  limitation  a  merger  or consolidation  of  the  Corporation  and
     excluding  any  transaction  as  to which  Sections  4(d)(i)  through  (vi)
     apply),  in each case as a result of which shares of Steel Stock  shall  be
     converted  into  the right to receive stock, securities or  other  property
     (including  cash or any combination thereof), (each of the foregoing  being
     referred  to herein as a ''Transaction''), each share of this Series  which
     is  not  converted  into the right to receive stock,  securities  or  other
     property   in   connection  with  such  Transaction  shall  thereafter   be
     convertible  into  the kind and amount of shares of stock,  securities  and
     other property (including cash or any combination thereof) receivable  upon
     the  consummation of such Transaction by a holder of that number of  shares
     or  fraction thereof of Steel Stock into which one share of this Series was
     convertible immediately prior to such Transaction, assuming such holder  of
     Steel Stock (i) is not a person with which the Corporation consolidated  or
     into  which the Corporation merged or which merged into the Corporation  or
     to  which  such  sale  or  transfer  was  made,  as  the  case  may  be  (a
     ''Constituent Person''), or an affiliate of a Constituent Person  and  (ii)
     failed  to  exercise his rights of election, if any,  as  to  the  kind  or
     amount  of stock, securities and other property (including cash) receivable
     upon  such  Transaction  (provided that if the kind  or  amount  of  stock,
     securities  and  other  property  (including  cash)  receivable  upon  such
     Transaction  is  not  the  same  for each  share  of  Steel  Stock  of  the
     Corporation  held immediately prior to such Transaction  by  other  than  a
     Constituent  Person or an affiliate thereof and in respect  of  which  such
     rights  of election shall not have been exercised (''non-electing share''),
     then  for  the purpose of this Section 4(f) the kind and amount  of  stock,
     securities  and  other  property  (including  cash)  receivable  upon  such
     Transaction by each non-electing share shall be deemed to be the  kind  and
     amount  so receivable per share by a plurality of the non-electing shares).
     The  Corporation shall not be a party to any Transaction unless  the  terms
     of  such  Transaction are consistent with the provisions  of  this  Section
     4(f)  and  it  shall  not  consent  or  agree  to  the  occurrence  of  any
     Transaction  until the Corporation has entered into an agreement  with  the
     other  party or parties to such transaction for the benefit of the  holders
     of  shares of this Series that will contain provisions enabling the holders
     of  such  shares that remain outstanding after such Transaction to  convert
     into  the  consideration  received  by  holders  of  Steel  Stock  at   the
     Conversion  Price  in  effect immediately prior to  such  Transaction.  The
     provisions  of  this  Section  4(f) shall  similarly  apply  to  successive
     Transactions.

        (g)  The  reclassification of common stock into  which  shares  of  this
     Series are then convertible into securities which include securities  other
     than   such   common  stock  (other  than  any  reclassification   upon   a
     consolidation or merger to which Section 4(f) applies), shall be deemed  to
     involve (i) a distribution of such securities other than such common  stock
     to  all  holders  of  such  common stock (and the effective  date  of  such
     reclassification  shall  be  deemed  to  be  ''the  date  fixed   for   the
     determination of stockholders entitled to receive such distribution'')  and
     (ii)  a  subdivision or combination, as the case may be, of the  number  of
     shares  of  such  common  stock  outstanding  immediately  prior  to   such
     reclassification   into  the  number  of  shares  of  such   common   stock
     outstanding  immediately  thereafter  (and  the  effective  date  of   such
     reclassification  shall  be  deemed  to  be  the  effective  date  of  such
     subdivision or combination).

        (h)  If  the Corporation shall, by dividend or otherwise, distribute  to
     all  holders  of  Steel  Stock or other class of common  stock  into  which
     shares  of  this Series are then convertible shares of common  stock  other
     than  Steel  Stock or any class of common stock into which shares  of  this
     Series   are  then  convertible,  each  share  of  this  Series  shall   be
     convertible,  in  addition to the number of shares of  Steel  Stock  and/or
     such  other  common  stock into which such share is then convertible,  into
     the number of shares of such other common stock receivable upon payment  of
     such  distribution to a holder of that number of shares or fraction thereof
     of  Steel  Stock or such other common stock into which one  share  of  this
     Series  was convertible immediately prior to the record date fixed for  the
     determination  of  stockholders  entitled  to  receive  such  distribution.
     Shares  of  this Series shall become so convertible immediately  after  the
     opening  of business on the day next following such record date (except  as
     provided  in  Section  4(m)).  In addition, a  Conversion  Price  shall  be
     established  with respect to such common stock in an amount  equal  to  the
     quotient  of (i) the initial liquidation preference of $50.00 per share  of
     this  Series  divided by (ii) the number of shares or fraction  thereof  of
     such  common stock that a holder of one share of Steel Stock or such  other
     common  stock  into which shares of this Series are then convertible  would
     be  entitled to receive on the payment date for such distribution from  and
     after  any  such date of determination of stockholders entitled to  receive
     such  distribution and, thereafter, Conversion Price adjustments as  nearly
     as  equivalent in type as may be practicable to the adjustments pursuant to
     Sections  4(d) through (f) which are to be made in respect of  Steel  Stock
     shall  be  made  in respect of shares of such common stock. Notwithstanding
     the  foregoing and the provisions of Section 4(d)(iii), if the  Corporation
     shall make such a distribution in common stock and, thereafter, all of  the
     shares  of  such  common stock cease to be outstanding, on  the  date  such
     shares  of  common  stock cease to be outstanding (x) the  shares  of  this
     Series shall cease to be convertible into shares of such common stock,  (y)
     a  distribution  of  shares of such common stock shall be  deemed  to  have
     occurred on such date and (z) the Conversion Price for the class of  common
     stock  upon which such distribution was made, or if no shares of such class
     are  then  outstanding  because shares of such  class  were  exchanged  for
     shares  of  another class of common stock, of such other  class  of  common
     stock,  shall  be adjusted in the manner set forth in Section 4(d)(iii)  to
     the   same  extent  as  if  shares  of  the  common  stock  in  which  such
     distribution  was  made were within the meaning of the term  ''Securities''
     in Section 4(d)(iii).

        (i)  After  the date, if any, on which all outstanding shares  of  Steel
     Stock  or  of any other common stock into which shares of this  Series  are
     then  convertible are exchanged for shares of another class of common stock
     (as  provided  in  the Certificate of Incorporation), each  share  of  this
     Series  shall thereafter be convertible into the number of shares  of  such
     other  class of common stock receivable upon such exchange by a  holder  of
     that  number of shares or fraction thereof of Steel Stock and/or such other
     common  stock  into which shares of this Series are then  convertible  into
     which  one share of this Series was convertible immediately prior  to  such
     exchange.  From  and after any such exchange, Conversion Price  adjustments
     as  nearly equivalent as may be practicable to the adjustments pursuant  to
     Sections  4(d)  through 4(h) which, prior to such exchange,  were  made  in
     respect of Steel Stock and/or such other common stock into which shares  of
     this  Series  are then convertible shall instead be made pursuant  to  such
     Sections  4(d)  through 4(h) in respect of shares of such  other  class  of
     common stock.

       (j) Subject to the provisions of Section 4(k), if:

           (i) the Corporation takes any action that would require an adjustment
        of the Conversion Price pursuant to Sections 4(d) through (i); or

           (ii)  there  shall  be  any consolidation  or  merger  to  which  the
        Corporation  is  a party and for which approval of any  stockholders  of
        the  Corporation  is  required,  or the  sale  or  transfer  of  all  or
        substantially  all of the assets of the Corporation or  the  U.S.  Steel
        Group; or

           (iii)  there  shall  occur the voluntary or involuntary  liquidation,
        dissolution or winding up of the Corporation; or

           (iv)  the  Corporation or any of its Subsidiaries  shall  commence  a
        tender  offer or exchange offer for all or a portion of the  outstanding
        shares  of  Steel  Stock  (or shall amend any such  tender  or  exchange
        offer),

        then  the  Corporation shall cause to be filed with the  Transfer  Agent
        and shall cause to be mailed to the holders of shares of this Series  at
        their   addresses  as  shown  on  the  stock  transfer  books   of   the
        Corporation, as promptly as possible, but at least 15 days prior to  the
        earliest  applicable date hereinafter specified, a  notice  stating,  as
        applicable,  (A) the proposed record date for a dividend or distribution
        or  the  proposed  effective  date  of a  consolidation,  merger,  sale,
        transfer,  liquidation, dissolution or winding up, (B) the  date  as  of
        which  it  is  expected that holders of Steel Stock of record  shall  be
        entitled  to  exchange  their shares of Steel Stock  for  securities  or
        other  property,  if  any, deliverable upon such consolidation,  merger,
        sale,  transfer, liquidation, dissolution or winding up or (C) the  date
        on  which  such  tender or exchange offer commenced, the date  on  which
        such  tender  or exchange offer is scheduled to expire unless  extended,
        the  consideration offered and the other material terms thereof (or  the
        material  terms  of any amendment thereto). Failure to give  or  receive
        such  notice  or  any defect therein shall not affect  the  legality  or
        validity of the related transaction.

       (k) If the Corporation intends:

           (i)  to  effect a U.S. Steel Group Special Event or a Marathon  Group
        Special Event; or

           (ii) exchange shares of Steel Stock for Marathon Stock or Delhi Stock
        following  a  Disposition of all or substantially all of the  properties
        and assets of the U.S. Steel Group,

        then  the  Corporation shall cause to be filed with the  Transfer  Agent
        and shall cause to be mailed to the holders of shares of this Series  at
        their   addresses  as  shown  on  the  stock  transfer  books   of   the
        Corporation, not less than 45 days prior to the Steel Group  Disposition
        Dividend or the Steel Group Disposition Redemption and not less than  30
        days  prior  to any other U.S. Steel Group Special Event,  any  Marathon
        Group  Special Event or any such exchange of Steel Stock for  shares  of
        Marathon Stock or Delhi Stock, a notice stating, as applicable, (A)  the
        record  date  for any dividend that is a U.S. Steel Group Special  Event
        or  a Marathon Group Special Event, (B) the date on which any redemption
        or  exchange that is a U.S. Steel Group Special Event, a Marathon  Group
        Special  Event  or  an exchange of Steel Stock for  shares  of  Marathon
        Stock  or Delhi Stock is expected to become effective, and the  date  as
        of  which  it  is  expected that holders of record  of  Steel  Stock  or
        Marathon  Stock  shall  be entitled to exchange their  shares  of  Steel
        Stock  or Marathon Stock, respectively, for securities or other property
        deliverable  upon such redemption or exchange or (C) the date  on  which
        the  Steel  Group Tender or Exchange Offer or the Marathon Group  Tender
        or  Exchange  Offer commenced, the consideration offered and  the  other
        material   terms  thereof  (or  the  material  terms  of  any  amendment
        thereto).  In addition, from and after any exchange of Steel  Stock  for
        Delhi  Stock, effected in accordance with Section 2(b)(i) of Division  I
        of  the Certificate of Incorporation, the Corporation shall give similar
        notice of its intention to exchange Delhi Stock for shares of the  Delhi
        Group Subsidiary, if Steel Stock has been exchanged therefor, or to  pay
        a   dividend  on,  or  redeem  shares  of,  Delhi  Stock  following  the
        Disposition of all or substantially all of the properties and assets  of
        the  Delhi  Group.  Failure to give or receive any such  notice  or  any
        defect  therein shall not affect the legality or validity of the related
        transaction. In the event of any conflict between the notice  provisions
        of  this paragraph (k) and paragraph (j) above, the notice provisions of
        this paragraph (k) shall govern.

        (l)  Whenever  the Conversion Price is adjusted as herein provided,  the
     Corporation  shall  promptly  file with the  Transfer  Agent  an  officer's
     certificate  setting forth the Conversion Price after such  adjustment  and
     setting  forth  a  brief statement of the facts requiring such  adjustment,
     which certificate shall be prima facie evidence of the correctness of  such
     adjustment.  Promptly after delivery of such certificate,  the  Corporation
     shall  prepare a notice of such adjustment of the Conversion Price  setting
     forth  the  adjusted  Conversion  Price and  the  effective  date  of  such
     adjustment  and shall send such notice of such adjustment of the Conversion
     Price by first class mail, postage prepaid, to the holder of each share  of
     this  Series  at  such holder's address as the same appears  on  the  stock
     transfer books of the Corporation.

        (m)  In  any  case  in  which Section 4(d)  or  4(h)  provides  that  an
     adjustment  shall become effective on the day next following a record  date
     for  an event, the Corporation may defer until the occurrence of such event
     (A)  issuing to the holder of any share of this Series converted after such
     record  date and before the occurrence of such event the additional  shares
     of  Steel Stock or any other common stock of the Corporation issuable  upon
     such  conversion  by reason of the adjustment required by such  event  over
     and  above  the number of shares of Steel Stock or such other common  stock
     issuable  upon such conversion before giving effect to such adjustment  and
     (B)  paying  to  such  holder any amount in cash in lieu  of  any  fraction
     thereof pursuant to Section 4(c).

        (n)  For purposes of this Section 4, the number of shares of Steel Stock
     or  any other common stock of the Corporation at any time outstanding shall
     not  include  any  shares of Steel Stock or such other  common  stock  then
     owned  or held by or for the account of Corporation. The Corporation  shall
     not  pay  a dividend or make any distribution on shares of Steel  Stock  or
     such other common stock held in the treasury of the Corporation.

        (o) There shall be no adjustment of the Conversion Price in case of  the
     issuance  of  any stock of the Corporation in a reorganization, acquisition
     or  other  similar  transaction except as specifically set  forth  in  this
     Section  4.  If any action or transaction would require adjustment  of  any
     Conversion Price established hereunder pursuant to more than one  paragraph
     of  this  Section 4, only the adjustment which would result in the  largest
     reduction of such Conversion Price shall be made.

        (p) The Corporation covenants that it will at all times reserve and keep
     available,  free  from  preemptive rights, out  of  the  aggregate  of  its
     authorized  but  unissued shares of Steel Stock and/or, if  the  shares  of
     this   Series  are  then  convertible  into  other  common  stock  of   the
     Corporation, such other common stock, or its issued shares of  Steel  Stock
     or  such  other common stock, as the case may be, held in its treasury,  or
     both,  for  the purpose of effecting conversion of shares of  this  series,
     the  full  number  of  shares of Steel Stock or  such  other  common  stock
     deliverable  upon the conversion of all outstanding shares of  this  Series
     not  theretofore converted. For purposes of this Section 4(p),  the  number
     of  shares  of  Steel  Stock  or such other  common  stock  that  shall  be
     deliverable  upon the conversion of all outstanding shares of  this  Series
     shall  be  computed as if at the time of computation all  such  outstanding
     shares were held by a single holder.

     The  Corporation covenants that any shares of Steel Stock or  other  common
  stock  of  the  Corporation issued upon conversion of shares  of  this  Series
  shall be validly issued, fully paid and nonassessable.

     The  Corporation shall endeavor to list the shares of Steel Stock or  other
  common  stock  of the Corporation required to be delivered upon conversion  of
  shares  of  this Series, prior to such delivery, upon each national securities
  exchange, if any, upon which the outstanding Steel Stock or such other  common
  stock is listed at the time of such delivery.

     Prior  to  the  delivery of any securities that the  Corporation  shall  be
  obligated   to  deliver  upon  conversion  of  shares  of  this  Series,   the
  Corporation  shall  endeavor to comply with all federal  and  state  laws  and
  regulations thereunder requiring the registration of such securities with,  or
  any  approval  of  or  consent to the delivery thereof  by,  any  governmental
  authority.

        (q)  The Corporation will pay any and all documentary, stamp or  similar
     issue  or  transfer taxes payable in respect of the issue  or  delivery  of
     shares  of  Steel  Stock or other securities or property on  conversion  of
     shares  of  this  Series  pursuant  hereto;  provided,  however,  that  the
     Corporation  shall not be required to pay any tax that may  be  payable  in
     respect  of  any transfer involved in the issue or delivery  of  shares  of
     Steel  Stock or other securities or property in a name other than  that  of
     the  holder  of such shares to be converted and no such issue  or  delivery
     shall  be  made  unless  and  until the person  requesting  such  issue  or
     delivery  has  paid  to  the Corporation the amount  of  any  such  tax  or
     established, to the reasonable satisfaction of the Corporation,  that  such
     tax has been paid.

     5.  Voting.  The  shares of this Series shall not have any  voting  powers,
  either general or special, except that:

        (a)  Unless  the vote or consent of the holders of a greater  number  of
     shares  shall  then be required by law, the consent of the  holders  of  at
     least  662/3%  of all of the shares of this Series at the time outstanding,
     given  in  person or by proxy, either in writing or by a vote at a  meeting
     called for the purpose at which the holders of shares of this Series  shall
     vote  together  as  a separate class, shall be necessary  for  authorizing,
     effecting or validating the amendment, alteration or repeal of any  of  the
     provisions  of  the  Certificate of Incorporation  or  of  any  certificate
     amendatory  thereof or supplemental thereto (including any  Certificate  of
     Designation  and Terms or any similar document relating to  any  series  of
     Preferred  Stock)  so  as to affect adversely the powers,  preferences,  or
     rights,  of  this  Series.  The increase of the authorized  amount  of  the
     Preferred  Stock,  or the creation or authorization of any  shares  of  any
     other  class  of stock of the Corporation ranking prior to or on  a  parity
     with the shares of this Series as to dividends or upon liquidation, or  the
     reclassification of any authorized stock of the Corporation into  any  such
     parity  shares,  or  the creation or authorization  of  any  obligation  or
     security  convertible  into or evidencing the right to  purchase  any  such
     prior  or parity shares shall not be deemed to affect adversely the powers,
     preferences or rights of this Series.

        (b)  Unless  the vote or consent of the holders of a greater  number  of
     shares  shall  then be required by law, the consent of the  holders  of  at
     least  662/3% of all of the shares of this Series and all other  series  of
     Preferred  Stock ranking on a parity with shares of this Series, either  as
     to  dividends or upon liquidation, at the time outstanding, given in person
     or  by  proxy, either in writing or by a vote at a meeting called  for  the
     purpose  at  which  the  holders of shares of this Series  and  such  other
     series  of  Preferred Stock shall vote together as a single  class  without
     regard  to  series,  shall  be  necessary  for  authorizing,  effecting  or
     validating  the  issuance  of any shares of  any  class  of  stock  of  the
     Corporation  ranking prior to the shares of this Series as to dividends  or
     upon  liquidation, or the reclassification of any outstanding stock of  the
     Corporation  into any such prior shares, or the issuance of any  obligation
     or  security convertible into or evidencing the right to purchase any  such
     prior shares.

        (c)  Unless  the vote or consent of the holders of a greater  number  of
     shares  shall  then be required by law, the consent of the  holders  of  at
     least  a majority of all of the shares of this Series and all other  series
     of  Preferred  Stock  ranking on a parity with this Series,  either  as  to
     dividends or upon liquidation, at the time outstanding, given in person  or
     by  proxy,  either  in  writing or by a vote at a meeting  called  for  the
     purpose  at  which  the  holders of shares of this Series  and  such  other
     series  of  Preferred Stock shall vote together as a single  class  without
     regard  to  series,  shall  be  necessary  for  authorizing,  effecting  or
     validating the merger or consolidation of the Corporation into or with  any
     other  corporation if such merger or consolidation would  adversely  affect
     the  powers, preferences or rights of this Series or such other  series  of
     Preferred Stock or if, after such merger or consolidation, there  shall  be
     outstanding  any shares of any class of stock ranking prior to  the  shares
     of  this  Series as to dividends or upon liquidation or any  obligation  or
     security  convertible  into or evidencing the right to  purchase  any  such
     prior  shares  (except  such  stock,  securities  or  obligations  of   the
     Corporation as may have been outstanding immediately preceding such  merger
     or consolidation).

        (d)  If,  on the date used to determine stockholders of record  for  any
     meeting  of  stockholders  for the election  of  directors,  a  default  in
     preference  dividends  on the Preferred Stock shall exist,  the  number  of
     directors  constituting the Board of Directors shall be increased  by  two,
     and  the  holders of the Preferred Stock of all series (whether or not  the
     holders  of  such series of Preferred Stock would be entitled to  vote  for
     the  election of directors if such default in preference dividends did  not
     exist),  shall have the right at such meeting, voting together as a  single
     class  without regard to series, to the exclusion of the holders of  Common
     Stock  of  the  Corporation, to elect two directors of the  Corporation  to
     fill  such  newly  created  directorships. Each  director  elected  by  the
     holders   of  shares  of  Preferred  Stock  (herein  called  a  ''Preferred
     Director''),  shall continue to serve as such director for  the  full  term
     for  which  such  director  shall have been elected,  notwithstanding  that
     prior  to  the  end  of such term a default in preference  dividends  shall
     cease  to  exist. Any Preferred Director may be removed without  cause  by,
     and  shall not be removed without cause except by, the vote of the  holders
     of  record of the outstanding shares of Preferred Stock, voting together as
     a  single class without regard to series, at a meeting of the stockholders,
     or  of the holders of shares of Preferred Stock, called for the purpose. So
     long  as a default in any preference dividends on the Preferred Stock shall
     exist  (A) any vacancy in the office of a Preferred Director may be  filled
     (except  as  provided  in the following clause (B))  by  an  instrument  in
     writing  signed  by  the remaining Preferred Director and  filed  with  the
     Corporation and
       (B) in the case of the removal of any Preferred Director, the vacancy may
     be  filled  by  the  vote  of  the holders of  the  outstanding  shares  of
     Preferred  Stock,  voting  together as a single  class  without  regard  to
     series,  at  the  same meeting at which such removal shall be  voted.  Each
     director  appointed as aforesaid by the remaining Preferred Director  shall
     be  deemed,  for all purposes hereof, to be a Preferred Director.  Whenever
     the  term of office of the Preferred Directors shall end and no default  in
     preference dividends shall exist, the number of directors constituting  the
     Board  of  Directors  shall be reduced by two. For the purposes  hereof,  a
     ''default in preference dividends'' on the Preferred Stock shall be  deemed
     to  have occurred whenever the amount of accrued and unpaid dividends  upon
     any  series  of  the  Preferred  Stock shall  be  equivalent  to  six  full
     quarterly  dividends or more (whether or not consecutive), and,  having  so
     occurred, such default shall be deemed to exist thereafter until, but  only
     until,  all accrued dividends on all shares of Preferred Stock of each  and
     every  series  then outstanding shall have been paid for all past  dividend
     periods.

     available   for  distribution  to  stockholders,  before  any  payment   or
     distribution  shall  be  made  on any class of  the  common  stock  of  the
     Corporation or on any other class of stock ranking junior to the  Preferred
     Stock  upon liquidation, the amount of $50 per share, plus a sum  equal  to
     all  dividends  (whether or not earned or declared) on such shares  accrued
     and unpaid thereon to the date of final distribution.

     securities  or  other  consideration)  of  all  or  substantially  all  the
     property  and assets of the Corporation nor the merger or consolidation  of
     the  Corporation  into  or  with any other corporation  or  the  merger  or
     consolidation of any other corporation into or with the Corporation,  shall
     be  deemed  to  be a dissolution, liquidation or winding up,  voluntary  or
     involuntary, for the purposes of this Section 6.

        (c) After the payment to the holders of the shares of this Series of the
     full  preferential amounts provided for in this Section 6, the  holders  of
     shares  of this Series as such shall have no right or claim to any  of  the
     remaining assets of the Corporation.

     involuntary,  shall  be insufficient to pay in full all  amounts  to  which
     such  holders  are entitled pursuant to Section 6(a), no such  distribution
     shall  be  made on account of any shares of any other class  or  series  of
     Preferred  Stock  ranking on a parity with the shares of this  Series  upon
     such   dissolution,   liquidation  or  winding  up   unless   proportionate
     distributive  amounts  shall  be paid on account  of  the  shares  of  this
     Series, ratably, in proportion to the full distributable amounts for  which
     holders  of  all  such parity shares are respectively  entitled  upon  such
     dissolution, liquidation or winding up.

     7.  Ranking.  For purposes of this resolution, any stock of  any  class  or
  classes of the Corporation shall be deemed to rank:

        (a)  prior to the shares of this Series, either as to dividends or  upon
     liquidation, if the holders of such class or classes shall be  entitled  to
     the  receipt  of  dividends or of amounts distributable  upon  dissolution,
     liquidation  or  winding  up  of  the  Corporation,  whether  voluntary  or
     involuntary, as the case may be, in preference or priority to  the  holders
     of shares of this Series;

     or  upon  liquidation, whether or not the dividend rates, dividend  payment

     provisions, if any, be different from those of this Series, if the  holders
     of  such  stock shall be entitled to the receipt of dividends or of amounts
     distributable  upon  dissolution,  liquidation  or  winding   up   of   the
     Corporation,  whether voluntary or involuntary, as  the  case  may  be,  in
     proportion  to  their  respective dividend  rates  or  liquidation  prices,
     without  preference or priority, one over the other, as between the holders
     of such stock and the holders of shares of this Series; and

        (c)  junior  to  shares of this Series, either as to dividends  or  upon
     liquidation,  if  such  class  or classes shall  be  the  Series  A  Junior
     Preferred  Stock issued by the Corporation pursuant to the Restated  Rights
     Agreement  or  if such class or classes shall be any class of common  stock
     of  the  Corporation or if the holders of shares of this  Series  shall  be
     entitled  to  receipt  of  dividends  or  of  amounts  distributable   upon
     dissolution,  liquidation  or  winding  up  of  the  Corporation,   whether

     the holders of shares of such class or classes.

stockholders  after  their election, and until their respective  successors  are
duly  elected and qualified. If the number of directors is changed, any increase

elected to any class shall hold office for a term which shall coincide with  the
terms  of  the  other directors in such class and until his  successor  is  duly
elected and qualified.

disqualification  or other cause, a successor to hold office for  the  unexpired

by-laws  at  any regular or special meeting of the Board of Directors,  provided
that  notice of intention to adopt, amend or repeal the by-laws in whole  or  in
part  shall  have been included in the notice of meeting; or, without  any  such
notice, by a vote of two-thirds of the directors then in office.

  Stockholders may adopt, amend and repeal the by-laws at any regular or special
meeting  of the stockholders by an affirmative vote of two-thirds of the  shares
outstanding  and entitled to vote thereon, provided that notice of intention  to
adopt,  amend or repeal the by-laws in whole or in part shall have been included
in the notice of the meeting.

consent.

what  extent,  and  at  what  times and places, and under  what  conditions  and
regulations, the accounts and books of the Corporation, or any of them, shall be
open  to  the inspection of the stockholders, and no stockholder shall have  any
right  to inspect any account or book or document of the Corporation, except  as
conferred  by  law  or  authorized  by  the  Board  of  Directors,  or  by   the
stockholders.

   Tenth:  The  directors may from time to time declare such dividends  as  they
shall deem advisable and proper, subject to the provisions of Article Fourth and
to  such  restrictions  as  may be imposed by law,  and  pay  the  same  to  the
stockholders at such times as they shall fix.

   The  Board of Directors shall have power to issue bonds, debentures, or other
obligations, either non-convertible or convertible into the Corporation's stock,
subject to the provisions of Article Fourth and upon such terms, in such  manner
and  under such conditions in conformity with law, as may be fixed by the  Board
of Directors prior to the issue of such bonds, debentures or other obligations.

   Eleventh:  No director shall be personally liable to the Corporation  or  its
stockholders  for  monetary damages for any breach of  fiduciary  duty  by  such
director as a director, except (i) for 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)  pursuant to Section 174 of the Delaware General Corporation Law, or  (iv)
for  any  transaction  from  which the director  derived  an  improper  personal
benefit.  No amendment to or repeal of this Article Eleventh shall apply  to  or
have  any  effect on the liability or alleged liability of any director  of  the
Corporation  for  or  with  respect to any acts or omissions  of  such  director
occurring prior to such amendment or repeal.

   Twelfth: The powers and authorities hereinbefore conferred upon the Board  of
Directors  are  in furtherance and not in limitation of those conferred  by  the
laws of the State of Delaware.

   Thirteenth: The Corporation reserves the right at any time and from  time  to
time  to  amend,  alter,  change  or  repeal any  provision  contained  in  this
Certificate of Incorporation in the manner now or hereafter prescribed  by  law;
and  all  rights preferences and privileges of whatsoever nature conferred  upon
stockholders, directors or any other persons whomsoever by and pursuant to  this
Certificate  of  Incorporation in its present form or as hereafter  amended  are
granted subject to the rights reserved in this Article.

  In Witness Whereof, this Restated Certificate of Incorporation, which restates
and  integrates  and does not further amend the provisions of the  Corporation's
Certificate  of  Incorporation, as heretofore amended  and  supplemented,  there
being  no  discrepancies  between those provisions and the  provisions  of  this
Restated Certificate of Incorporation, and having been duly adopted by the Board
of Directors of the Corporation in accordance with the provisions of Section 245
of  the  General Corporation Law of the State of Delaware, has been executed  on
the 1st day of May, 1999.
