                           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

                           amount of any dividends or other distribu tions
                           (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

                           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 ex changed, notwithstanding the
                           failure to surrender such certificates.

                                    (vii) The Corporation will pay any and

                           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
                           Corpora tion the amount of any such tax, or has
                           established to the satisfaction of the
                           Corporation that such tax has been paid.

                  the fifth Business Day prior to the applicable record
                  date or as of any other applicable date, of (A) the sum

                  share of the Delhi Stock shall have a number of votes

                           the provisions of this Certificate of
                           Incorporation.

                  2. The holders of shares of the Preferred Stock of each
         series shall be entitled to receive, when and as declared by the
         Board of Directors, out of funds legally available for the payment
         of dividends, dividends at the rates fixed by the Board of
         Directors for such series, and no more, before any dividends,
         other than dividends payable in Common Stock, shall be declared
         and paid, or set apart for payment, on the Common Stock with
         respect to the same dividend period.

                  3. Whenever, at any time, dividends on the then
         outstanding Preferred Stock as may be required with respect to any
         series outstanding shall have been paid or declared and set apart
         for payment on the then outstanding Preferred Stock, and after
         complying with respect to any retirement or sinking fund or funds
         for any series of Preferred Stock, the Board of Directors may,
         subject to the provisions of the resolution or resolutions
         creating any series of Preferred Stock, declare and pay dividends
         on the Common Stock, and the holders of shares of the Preferred

         series shall be entitled upon liquidation or dissolution or upon
         the distribution of the assets of the Corporation to such

         holders of shares of the Common Stock.

                  5. Except as otherwise provided by a resolution or
         resolutions of the Board of Directors creating any series of
         Preferred Stock or by the General Corporation Law of Delaware, the
         holders of shares of the Common Stock issued and outstanding shall

                  Section 1. Designation and Amount. This resolution shall

         which shall be "Series A Junior Preferred Stock", without par
         value, and the number of shares constituting such series shall be
         Eight Million (8,000,000).

                  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 Decem ber 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 divi dend
                  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
                  Pay ment 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, notwithstand
                  ing 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

                           other than as provided in subparagraph (ii) of
                           this section), or redeem or purchase or
                           otherwise acquire for consideration (except by
                           conversion into or ex change 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 Pre ferred
                           Stock;

                                    (ii) declare or pay dividends on or
  !                        make any other distributions on any shares of

                           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
                  Corpo ration 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 resolu
         tions 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 divi dends 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 Corpo ration 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 outstand ing
         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 case 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
                  transac tion 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 re deemed, 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 Corpora tion 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 responsi bility 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 Corpora
                  tion 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
                           disso lution, 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 volun tary 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 66 2/3% 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 Certificate of Incorporation or of
                  any certificate amendatory thereof or supple mental
                  thereto (including any Certificate of Designation,
                  Preferences and Rights of 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 or
         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 calender
                  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 immedi ately 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 Corpora tion 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 Corpo ration 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

                  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
                  redemp tion prices per share if redeemed during the
                  twelve-month period beginning April 1 of the year

                           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

                           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 re
                           deemed 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
                           Disposi tion 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
                           shared 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 liquida tion
                  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 conver sion 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 accom panied
                  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 Corpora tion
                  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 conver sion
                  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 out
                           standing Steel Stock into a greater number of
                           shares or (C) combine the outstanding Steel
                           Stock into a smaller number of shares, then the
                           Conver sion 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 ac count 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 Corpo ration), 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 deter mined 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 mean ings 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 12 1/2% 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 12 1/2% 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 pur chased 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 Conver sion 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 Corpo ration 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, post age 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 Conver sion 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 hereun der
                  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 calcula tions
                  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 (includ ing 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 Trans action
                  (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 provi sions 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 succes sive 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 determi nation 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
                  practica ble 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 convert ible 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 pursu
                  ant to Sections 4(d) through 4(h) which, prior to such

                  prepare a notice of such adjustment of the Conversion
                  Price setting forth the adjusted Conversion Price and the

                           (m) In any case in which Section 4(d) or 4(h)
                  provides that an adjust ment 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

                  Stock or any other com mon 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

                  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

                  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 adjust ment 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

                  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

                  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

         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 registra tion of such securities with, or 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

                  however, that the Corporation shall not be required to

                  unless and until the person requesting such issue or

                           (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
                  consolida tion).

                           (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 divi dends 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 filled with the
                  Corporation and (B) in the case of the removal of any
                  Preferred Director, the vacancy may be filed 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.

                  6.    Liquidation Rights.

                           (a) Upon the dissolution, liquidation or winding
                  up of the Corporation, whether voluntary or involuntary,
                  the holders of the shares of this Series shall be
                  entitled to receive out of the assets of the Corporation
                  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.

                           (b) Neither the sale, lease of exchange (for
                  cash, shares of stock, securi ties 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 purpose 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.

                           (d) In the event the assets of the Corporation
                  available for distribution to the holders of shares of
                  this Series upon any dissolution, liquidation or winding
                  up of the Corporation, whether voluntary or 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 propor
                  tion 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;

                           (b) on a parity with the shares of this Series,
                  either as to dividends or upon liquidation, whether or
                  not he dividend rates, dividend payment dates or
                  redemption or liquidation prices per share or sinking
                  fund 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 liquida tion, 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
                  voluntary or involuntary, as the case may be, in
                  preference or priority to the holders of shares of such
                  class or classes.

                  8. Determinations by the Board of Directors. Any
         determinations made by the Board of Directors of the Corporation
         under any provision of this Resolution shall be final and binding
         on all stockholders (including holders of shares of this Series)
         of the Corporation.

                  9. Definitions. Unless otherwise defined herein, terms

         on the New York Stock Exchange Composite Tape or, if such common
         stock is not listed or admitted to trading on the NYSE, on the
         principal national securities exchange on which such common stock

         common stock on such day shall not have been reported through

         "ex" date for such other event shall be adjusted by multiplying
         such Closing Price by the same fraction by which the Conversion
         Price is so required to be adjusted as a result of such other

         Day on and after the "ex" date for such other event shall be
         adjusted by multiplying such Closing Price by the reciprocal of
         the fraction by which the Conversion Price is so required to be

         date for the issuance or distribution requiring such computation

         any adjustment required pursuant to clause (ii) of this proviso,
         the Closing Price for each Trading Day on or after such "ex" date
         shall be adjusted by adding thereto the amount of any cash and the
         fair market value on the day in question (as determined by the

         of such value for purposes of Section 4(d)(iii) or (iv)) of the
         evidences of indebtedness, shares of capital stock or assets being
         distributed applicable to one share of the applicable class of
         common stock of the Corporation as of the close of business on the
         day before such "ex" date. For purposes of this definition, the

         subdivision or combination of shares of such common stock, means
         the first date on which such common stock trades regular way on

third annual meeting of the stockholders thereafter, and in the case of

the stockholders the directors elected to succeed those whose terms expire
shall be identified as being of the same class as the directors they
succeed and shall be elected to hold office for a term to expire at the
third annual meeting of the stockholders after their election, and until
their respective successors are duly elected and qualified. If the number
of directors is changed, any increase or decrease in directors shall be
apportioned among the classes so as the maintain all classes as equal in
number as possible, and any additional director 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.

         In the case of any increase in the number of directors of the
Corporation, the additional director or directors shall be elected by the
Board of Directors.

         In the case of any vacancy in the Board of Directors from death,
resignation, disqualifica tion or other cause, a successor to hold office
for the unexpired portion of the term of the director whose place shall be
vacant, and until the election of his successor, shall be elected by a

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.

conditions and regulation, the accounts and books of the Corporation, or
any of them, shall be open to the inspection of the stockholders, and no

of the Corpora tion, 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 knowing violation of law, (iii) pursuant to Section 174 of the Delaware
General Corporation Law, or (iv) for any transac tion from which the
director derived an improper personal benefit. No amendment to or repeal of
this Article Twelfth 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.

the Board of Directors are in furtherance and not in limitation of those
conferred by the laws of the State of Delaware.

from time to time to amend, alter, change or repeal any provisions
contained in this Certificate of Incorporation in the manner now or
hereafter prescribed by law, and all rights preferences and privileges of
whatso ever 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

of Incorporation, having been duly adopted by 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 2nd day of July, 2001.
