Exchange Date or Redemption Date. Such notice shall be sent by first-class mail,
postage prepaid, not less than 30 nor more than 60 days prior to the Exchange
Date or Redemption Date, as the case may be, and in any case to each holder of
the class of Common Stock to be exchanged or redeemed, at such holder's address
as the same appears on the stock transfer books of the Corporation. Neither the
failure to mail such notice to any particular holder of such class of Common
Stock nor any defect therein shall affect the sufficiency thereof with respect
to any other holder of such class of Common Stock.

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

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

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

     (v) Before any holder of shares of any class of Common Stock shall be
entitled to receive certificates representing shares of any capital stock or
cash and/or securities or other property to be received by such holder with
respect to such shares of such class of Common Stock pursuant to this Section 2,
such holder shall surrender at such office as the Corporation shall specify
certificates for such shares of such class of Common Stock, properly endorsed or
assigned for transfer (unless the Corporation shall waive such requirement). The
Corporation will as soon as practicable after such surrender of certificates
representing such shares of such class of Common Stock deliver to the person for
whose account such shares of such class of Common Stock

                                        6


were so surrendered, or to his nominee or nominees, certificates representing
the number of whole shares of the kind of capital stock or cash and/or
securities or other property to which he shall be entitled as aforesaid,
together with any fractional payment contemplated by Section 2(d)(iii). If
less than all of the shares of any class of Common Stock, represented by any
one certificate are to be redeemed, the Corporation shall issue and deliver a
new certificate for the shares of such class of Common Stock not redeemed.

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

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

merger or consolidation would adversely affect the powers or special rights of
such class of Common Stock either directly by amendment of this Restated

outstanding) by the affirmative vote of the holders of shares of Common Stock
having a majority of the votes entitled to be cast by the holders of all classes
of Common Stock, voting together as provided for in Section 3(a) and without a

operation of a retirement or sinking fund to be applied to the purchase or
redemption of such shares and, if such retirement or sinking fund be
established, the annual amount thereof and the terms and provisions relative to
the operation thereof;

     (v) Whether or not the shares of the series shall be convertible into or
exchangeable for shares of any other class or classes, with or without par
value, or of any other series of the same class, and, if provision is made for
conversion or exchange, the times, prices, rates, adjustments, and other terms
and conditions of such conversion or exchange;


                                       12


     (vi) Whether or not the shares of the series shall have voting rights, in
addition to the voting rights provided by law, and, if so, subject to the
limitation hereinafter set forth, the terms of such voting rights;

     (vii) The rights of the shares of the series in the event of voluntary or

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 Stock shall not be entitled to share therein.

     4. The holders of shares of the Preferred Stock of each series shall be
entitled upon liquidation or dissolution or upon the distribution of the assets
of the Corporation to such preferences as provided in the resolution or
resolutions creating such series of Preferred Stock, and no more, before any
distribution of the assets of the Corporation shall be made to the 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 have and possess the exclusive right to notice of
stockholders' meetings and the exclusive power to vote. The holders of shares of
the Preferred Stock issued and outstanding shall, in no event, be entitled to
more than one vote for each share of Preferred Stock held by them unless
otherwise required by law.

                  Terms of the Preferred Stocks are as follows:

     SERIES A JUNIOR PREFERRED STOCK

Section 1. Designation and Amount. This resolution shall provide for a single
series of preferred stock, the designation of 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 December in each year (each such date being referred to herein as
a "Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend
Payment Date after the first issuance of a share or fraction of a share of
Series A Junior Preferred Stock, in an amount per share (rounded to the nearest
cent) equal to the greater of (a) $5.00 or (b) subject to the provision for
adjustment hereinafter set forth, 100 times the aggregate per share amount of
all cash dividends, and 100 times the aggregate per share amount (payable in
kind) of all non-cash dividends or other distributions other than a dividend
payable in shares of Common Stock or a subdivision of the outstanding shares of
Common Stock (by

                                       13


reclassification or otherwise), to be or being declared on the Common Stock, par
value $1.00 per share, of the Corporation (the "Common Stock") with respect to
the same dividend period. If the Quarterly Dividend Payment Date is a Saturday,
Sunday or legal holiday then such Quarterly Dividend Payment Date shall be the
first immediately preceding calendar day which is not a Saturday, Sunday or
legal holiday. In the event the Corporation shall at any time after October 10,
1989 (the "Rights Declaration Date") (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock,
or (iii) combine the outstanding Common Stock into a smaller number of shares,
then in each such case the amount to which holders of shares of Series A Junior
Preferred Stock were entitled immediately prior to such event under clause (b)
of the preceding sentence shall be adjusted by multiplying such amount by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

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

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

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

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

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

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

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

                                       14


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

Section 4. Certain Restrictions.

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

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

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

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

                                       15


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

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

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

Section 6. Liquidation, Dissolution or Winding Up.

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

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

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

Section 8. Optional Redemption.

     (A) The Corporation shall have the option to redeem the whole or any part
of the Series A Junior Preferred Stock at any time on at least 30 days notice in
accordance with the provisions of paragraph

                                       16


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

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

                                       17


for his shares within one year after the date of redemption, the transfer agent
for the Series A Junior Preferred Stock shall, upon demand, pay over to the
Corporation such amount remaining on deposit and the transfer agent for the
Series A Junior Preferred Stock shall thereupon be relieved of all
responsibility to the holders of such shares and such holder of the shares of
the Series A Junior Preferred Stock so called for redemption shall look only to
the Corporation for the payment thereof.

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

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

Section 9. Ranking.

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

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

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

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

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

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

                                       18


     (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 Restated Certificate of Incorporation or
of any certificate amendatory thereof or supplemental thereto (including any
Certificate of Designation, Preferences and Rights or any similar document
relating to any series of Preferred Stock) so as to affect adversely the powers,
preferences, or rights, of this Series A Junior Preferred Stock. The increase of
the authorized amount of the Preferred Stock, or the creation, authorization or
issuance of any shares of any other class of stock of the Corporation ranking
prior to or on a parity with the shares of the Series A Junior Preferred Stock
as to dividends or upon liquidation, or the reclassification of any authorized
or outstanding stock of the Corporation into any such prior or parity shares, or
the creation, authorization or issuance of any obligation or security
convertible into or evidencing the right to purchase any such prior or parity
shares shall not be deemed to affect adversely the powers, preferences or rights
of the Series A Junior Preferred Stock.

Section 11. Fractional Shares. Series A Junior Preferred Stock may be issued in
fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series A Junior Preferred Stock.
                                        
        6.50% CUMULATIVE CONVERTIBLE PREFERRED STOCK (WITHOUT PAR VALUE)
     1. Designation. This resolution shall provide for a single series of
Preferred Stock, the designation of which shall be "6.50% Cumulative Convertible
Preferred Stock", without par value (hereinafter called this "Series"), and the
number of authorized shares constituting this Series is 6,900,000. Shares of
this Series shall have a stated value of $1.00 per share (which shall also be
the stated capital of each share). The number of authorized shares of this
Series may be reduced by further resolution adopted by the Board of Directors
and by the filing of a certificate pursuant to the provisions of the General
Corporation Law of the State of Delaware stating that such reduction has been so
authorized, but the number of authorized shares of this Series shall not be so
increased.
     2. Dividends.
     (a) The holders of shares of this Series shall be entitled to receive
dividends payable in cash at a rate of 6.50% per annum per share on the initial
liquidation preference of $50.00 per share. Such dividends shall be cumulative
from the date of original issue of such shares, and shall be payable, when, as
and if declared by the Board of Directors, out of funds legally available for
such purpose, on the last calendar day of March, June, September and December of
each year, commencing June 30, 1993, except that if such date is a Saturday,
Sunday or legal holiday, then such dividend shall be payable on the first
immediately preceding calendar day which is not a Saturday, Sunday or legal
holiday.

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

     (c) Except as hereinafter provided, no dividends shall be declared or paid
or set apart for payment on the Preferred Stock of any series ranking, as to
dividends, on a parity with or junior to this Series for any period unless full
cumulative dividends have been or contemporaneously are declared and paid on
this Series for all past dividend periods. When dividends are not paid in full,
as aforesaid, upon the shares of this Series and any other Preferred Stock
ranking on a parity as to dividends with this Series, all dividends declared
upon shares of this Series and any other Preferred Stock ranking on a parity as
to dividends with this Series shall be declared pro rata so that the amount of
dividends declared per share on this Series and such other Preferred Stock shall
in all cases bear to each other the same ratio that accrued dividends per share
on the shares of this Series and such

                                       19


other Preferred Stock bear to each other. Holders of shares of this Series shall
not be entitled to any dividends, whether payable in cash, property or stock, in
excess of full cumulative dividends, as herein provided, on this Series. No
interest, or sum of money in lieu of interest, shall be payable in respect of
any dividend payment or payments on this Series which may be in arrears.

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

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

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

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


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

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

                                       20


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

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

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

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

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

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

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

                                       21


exchange offer, as the case may be; provided, further, that, at the time of the
payment of such dividend on, or the consummation of such tender or exchange
offer for, Marathon Stock, there is another class of common stock, other than
Marathon Stock, of the Corporation then outstanding.

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

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

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

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

                                       22


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

(iv) The Corporation's obligation to provide an adequate amount of money for the
payment of the Redemption Price necessary to effect any redemption in accordance
with this Section 3 shall be deemed fulfilled if, on or before the applicable
Redemption Date, the Corporation shall deposit with a bank or trust company that
has an office in the Borough of Manhattan, City of New York, and that has, or is
an affiliate of a bank or trust company that has, a capital and surplus of at
least $50,000,000, an amount of money adequate for the payment of the aggregate
Redemption Price necessary for such redemption in accordance with the terms
hereof, in trust, with irrevocable instructions that such money be applied to
the redemption of the shares of this Series so called for redemption. If such
redemption is conditioned upon the payment of the Steel Group Disposition
Dividend or payment of the amount due as a result of the Steel Group Disposition
Redemption, the Corporation shall deposit such moneys and give such irrevocable
instructions in respect of such redemption, subject to the payment of such Steel
Group Disposition Dividend or payment of the amount due as a result of such
Steel Group Disposition Redemption, not later than the 30th day prior to the
date selected by the Board for the payment of such dividend on, or the
redemption of, Steel Stock, but in any event prior to the date the Corporation
declares such dividend or gives notice of such redemption, each in accordance
with Section 2 of Division I of the Certificate of Incorporation. No interest
shall accrue for the benefit of the holders of shares of this Series to be
redeemed on any money so payable by the Corporation in respect of any
redemption. Subject to applicable escheat laws, any money unclaimed at the end
of two years from the related Redemption Date shall revert to the general funds
of the Corporation, after which reversion the holders of such shares so called
for redemption shall look only to the general funds of the Corporation for the
payment of such money. In case fewer than all the shares of this Series
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares without cost to the holder thereof.
(v) Any shares of this Series which shall at any time have been redeemed shall,
upon the taking of any action required by law, have the status of authorized but
unissued shares of Preferred Stock, without designation as to series until such
shares are once more designated as part of a particular series by the Board of
Directors.
(vi) Notwithstanding the foregoing provisions of this Section 3, unless the full
cumulative dividends on all outstanding shares of this Series shall have been
paid or contemporaneously are declared and paid for all past dividend periods,
no shares of this Series shall be redeemed unless all outstanding shares of this
Series are simultaneously redeemed, and the Corporation shall not purchase or
otherwise acquire any shares of this Series; provided, however, that the
foregoing shall not prevent the purchase or acquisition of shares of this Series
pursuant to a purchase or exchange offer made on the same terms to holders of
all outstanding shares of this Series.

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

(a) Subject to and upon compliance with the provisions of this Section 4, a
holder of shares of this Series shall have the right, at such holder's option,
at any time, to convert such shares into the number of fully paid and
nonassessable shares of Steel Stock equal to the quotient of (i) the product of
the initial liquidation preference for shares of this Series of $50.00 per share
for such shares times the number of shares of this Series to be converted,
divided by (ii) the Conversion Price (as in effect on the date provided for in
the last paragraph of Section 4(b)) by surrendering the certificates
representing such shares to be converted, such surrender to be made in the
manner provided in accordance with this Section 4; provided that the right to
convert shares of this Series called for

                                       23


redemption pursuant to Section 3 shall terminate at the close of business on the
related Redemption Date, unless the Corporation shall default in making payment
of any moneys payable upon such redemption under Section 3 or, if the redemption
of shares of this Series is the result of a Steel Group Special Event or a
Marathon Group Special Event, the conditions to such redemption shall not have
been satisfied; and, provided, further, that if the Corporation has given notice
of a redemption pursuant to Section 3(c) which is conditioned on the occurrence
of the Steel Group Disposition Dividend or the Steel Group Disposition
Redemption, the right to convert shares of this Series shall terminate on the
31st day prior to the date selected by the Board of Directors for such
redemption. Any holder of any share or shares of this Series may only convert
whole shares of this Series and the Corporation shall not be obligated to issue
any fractional shares of this Series.

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

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

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

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

(c) No fractional shares or scrip representing fractions of shares of Steel
Stock or any other common stock of the Corporation shall be issued upon
conversion of any share of this Series. Instead of any fractional interest in a
share of Steel Stock or such other common stock that would otherwise be
deliverable upon the conversion of a share of this Series, the Corporation shall
pay to the holder

                                       24


of such share an amount in cash based upon the Closing Price of Steel Stock or
such other common stock on the Trading Day immediately preceding the date of
conversion. If more than one share shall be surrendered for conversion at one
time by the same holder, the number of full shares of Steel Stock or such other
common stock issuable upon conversion thereof shall be computed on the basis of
the aggregate number of shares of this Series so surrendered.

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

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

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

(iii) If the Corporation shall distribute to all holders of the Steel Stock any
shares of capital stock (other than common stock of the Corporation), evidences
of indebtedness, cash or other assets of the Corporation (including securities,
but excluding (w) any dividend or distribution referred to in Section 4(d)(i),
(x) any rights or warrants referred to in Section 4(d)(ii) or in the second or
third paragraph of this Section 4(d)(iii), (y) any dividend or distribution paid
exclusively in cash or (z) any stocks, securities or other property received as
a result of a transaction referred to in Section 4(f)) (any of the foregoing
being hereinafter referred to in this Section 4(d)(iii) as the "Securities"),
then in each such case the Conversion Price shall be adjusted so that it shall
equal the price determined by multiplying (I) the Conversion Price in effect
immediately prior to the close of business on the date fixed for the
determination of stockholders entitled to receive such
                                       25


distribution by (II) a fraction, the numerator of which shall be the Current
Market Price per share of the Steel Stock on the record date mentioned below
less the then fair market value (as determined by the Board of Directors) of the
portion of the Securities so distributed to one share of Steel Stock, and the
denominator of which shall be the Current Market Price per share of the Steel
Stock on the record date mentioned below. Such adjustment shall become effective
immediately at the opening of business on the day next following the record date
for the determination of stockholders entitled to receive such distribution
(except as provided in Section 4(m)).

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

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

(iv) If the Corporation shall, by dividend or otherwise, at any time distribute
to all holders of the Steel Stock cash (excluding any regular quarterly dividend
payable solely in cash, any cash that is distributed as part of a distribution
requiring a Conversion Price adjustment pursuant to Section 4(d)(iii) and cash
that is distributed in a merger or consolidation to which Section 4(f) applies)
in an aggregate amount that, together with (A) the aggregate amount of any other
distributions to all holders of the Steel Stock made exclusively in cash (to
which this Section 4(d)(iv) would otherwise apply) within the 12 months
preceding the date of payment of such distribution and in respect of which no
Conversion Price adjustment has been made and (B) all Excess Purchase Payments
in respect of each tender offer or exchange offer or other negotiated purchase
for Steel Stock concluded by the Corporation or any of its Subsidiaries within
the 12 months preceding the date of payment of such distribution and in respect
of which no Conversion Price adjustment has been made, exceeds an amount equal
to 12 1/2% of the product of the

                                       26


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 purchased shares) on such Purchase Date,
then the Conversion Price shall be adjusted so that it shall equal the price
determined by multiplying (I) such Conversion Price in effect immediately prior
to such Purchase Date by (II) a fraction, the numerator of which shall be the
Current Market Price per share of the Steel Stock on such Purchase Date less the
combined amount of Excess Purchase Payments and such cash so distributed
applicable to one share of Steel Stock and the denominator of which shall be
such Current Market Price per share on such Purchase Date. Such adjustment shall
become effective immediately prior to the opening of business on the day next
following such Purchase Date.

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

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

(e) No adjustment in the Conversion Price shall be required unless such
adjustment would require a cumulative increase or decrease of at least 1% in
such price; provided, however, that any adjustments that by reason of this
Section 4(e) are not required to be made shall be carried forward

                                       27


and taken into account in any subsequent adjustment until made; and provided,
further, that any adjustment shall be required and made in accordance with the
provisions of this Section 4 (other than this Section 4(e)) not later than such
time as may be required in order to preserve the tax-free nature of a
distribution to the holders of shares of Steel Stock or any other common stock
into which shares of this Series are convertible. Notwithstanding any other
provisions of this Section 4, the Corporation shall not be required to make any
adjustment of any Conversion Price established hereunder for the issuance of any
shares of common stock of the Corporation (including Steel Stock) pursuant to
any plan providing for the reinvestment of dividends or interest payable on
securities of the Corporation and the investment of additional optional amounts
in shares of such common stock under such plan. All calculations under this
Section 4 shall be made to the nearest 1/100 of a cent (with $.00005 being
rounded upward) or to the nearest 1/10,000 of a share (with .00005 of a share
being rounded upward), as the case may be.
(f) If the Corporation shall be a party to any transaction (including without
limitation a merger or consolidation of the Corporation and excluding any
transaction as to which Sections 4(d)(i) through (vi) apply), in each case as a
result of which shares of Steel Stock shall be converted into the right to
receive stock, securities or other property (including cash or any combination
thereof), (each of the foregoing being referred to herein as a "Transaction"),
each share of this Series which is not converted into the right to receive
stock, securities or other property in connection with such Transaction shall
thereafter be convertible into the kind and amount of shares of stock,
securities and other property (including cash or any combination thereof)
receivable upon the consummation of such Transaction by a holder of that number
of shares or fraction thereof of Steel Stock into which one share of this Series
was convertible immediately prior to such Transaction, assuming such holder of
Steel Stock (i) is not a person with which the Corporation consolidated or into
which the Corporation merged or which merged into the Corporation or to which
such sale or transfer was made, as the case may be (a "Constituent Person"), or
an affiliate of a Constituent Person and (ii) failed to exercise his rights of
election, if any, as to the kind or amount of stock, securities and other
property (including cash) receivable upon such Transaction (provided that if the
kind or amount of stock, securities and other property (including cash)
receivable upon such Transaction is not the same for each share of Steel Stock
of the Corporation held immediately prior to such Transaction by other than a
Constituent Person or an affiliate thereof and in respect of which such rights
of election shall not have been exercised ("non- electing share"), then for the
purpose of this Section 4(f) the kind and amount of stock, securities and other
property (including cash) receivable upon such Transaction by each non-electing
share shall be deemed to be the kind and amount so receivable per share by a
plurality of the non-electing shares). The Corporation shall not be a party to
any Transaction unless the terms of such Transaction are consistent with the
provisions of this Section 4(f) and it shall not consent or agree to the
occurrence of any Transaction until the Corporation has entered into an
agreement with the other party or parties to such transaction for the benefit of
the holders of shares of this Series that will contain provisions enabling the
holders of such shares that remain outstanding after such Transaction to convert
into the consideration received by holders of Steel Stock at the Conversion
Price in effect immediately prior to such Transaction. The provisions of this
Section 4(f) shall similarly apply to successive Transactions.
(g) The reclassification of common stock into which shares of this Series are
then convertible into securities which include securities other than such common
stock (other than any reclassification upon a consolidation or merger to which
Section 4(f) applies), shall be deemed to involve (i) a distribution of such
securities other than such common stock to all holders of such common stock (and
the effective date of such reclassification shall be deemed to be "the date
fixed for the determination of stockholders entitled to receive such
distribution") and (ii) a subdivision or combination, as the case may be, of the
number of shares of such common stock outstanding immediately prior to such
reclassification into the number of shares of such common stock outstanding
immediately thereafter (and the effective date of such reclassification shall be
deemed to be the effective date of such subdivision or combination).
(h) If the Corporation shall, by dividend or otherwise, distribute to all
holders of Steel Stock or other class of common stock into which shares of this
Series are then convertible shares of common stock other than Steel Stock or any
class of common stock into which shares of this Series are then convertible,
each share of this Series shall be convertible, in addition to the number of
shares of Steel Stock and/or such other common stock into which such share is
then convertible, into the number of shares of such other common stock
receivable upon payment of such distribution to a holder of that number of
shares or fraction thereof of Steel Stock or such other common stock into which
one share

                                       28


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

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

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

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

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

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

(iv) the Corporation or any of its Subsidiaries shall commence a tender offer or
exchange offer for all or a portion of the outstanding shares of Steel Stock (or
shall amend any such tender or exchange offer),   then the Corporation shall
cause to be filed with the Transfer Agent and shall cause to be mailed to the
holders of shares of this Series at their addresses as shown on the stock
transfer books of the Corporation, as promptly as possible, but at least 15 days
prior to the earliest applicable date hereinafter specified, a notice stating,
as applicable, (A) the proposed record date for a dividend or distribution or
the proposed effective date of a consolidation, merger, sale, transfer,
liquidation, dissolution or winding up, (B) the date as of which it is expected
that holders of Steel Stock of record shall be entitled to exchange their shares
of Steel Stock for securities or other property, if any, deliverable upon such
consolidation, merger, sale, transfer, liquidation, dissolution or winding up or
(C) the date on which such tender or exchange offer commenced, the date on

                                       29


which such tender or exchange offer is scheduled to expire unless extended, the
consideration offered and the other material terms thereof (or the material
terms of any amendment thereto). Failure to give or receive such notice or any
defect therein shall not affect the legality or validity of the related
transaction.

(k) If the Corporation intends:

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

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

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

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

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

                                       30


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

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

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

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

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

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

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

(a) Unless the vote or consent of the holders of a greater number of shares
shall then be required by law, the consent of the holders of at least 66 2/3% of
all of the shares of this Series at the time outstanding, given in person or by
proxy, either in writing or by a vote at a meeting called for the purpose at
which the holders of shares of this Series shall vote together as a separate
class, shall be necessary for authorizing, effecting or validating the
amendment, alteration or repeal of any of the provisions of the Certificate of
Incorporation or of any certificate amendatory thereof or supplemental thereto
(including any Certificate of Designation and Terms or any similar document
relating to any series of Preferred Stock) so as to affect adversely the powers,
preferences, or rights, of this Series. The increase of the authorized amount of
the Preferred Stock, or the creation or authorization of any shares of any other
class of stock of the Corporation ranking prior to or on a parity with the
shares of this Series as to dividends or upon liquidation, or the
reclassification of any authorized stock of the Corporation into any such parity
shares, or the creation or authorization of any obligation or security
convertible into or evidencing the right to purchase any such prior or parity
shares shall not be deemed to affect adversely the powers, preferences or rights
of this Series.   (b) Unless the vote or consent of the holders of a greater
number of shares shall then be required by law, the consent of the holders of at
least 66 2/3% of all of the shares of this Series and all other series of
Preferred Stock ranking on a parity with shares of this Series, either as to
dividends or upon

                                       31


liquidation, at the time outstanding, given in person or by proxy, either in
writing or by a vote at a meeting called for the purpose at which the holders of
shares of this Series and such other series of Preferred Stock shall vote
together as a single class without regard to series, shall be necessary for
authorizing, effecting or validating the issuance of any shares of any class of
stock of the Corporation ranking prior to the shares of this Series as to
dividends or upon liquidation, or the reclassification of any outstanding stock
of the Corporation into any such prior shares, or the issuance of any obligation
or security convertible into or evidencing the right to purchase any such prior
shares.

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

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

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

                                       32


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

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

(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 proportion to the full distributable amounts for which holders of
all such parity shares are respectively entitled upon such dissolution,
liquidation or winding up.

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

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

(b) on a parity with the shares of this Series, 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 this Series, if the holders of such stock shall be
entitled to the receipt of dividends or of amounts distributable upon

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

Directors then in office, though less than a quorum.   Directors of the
Corporation may be removed only for cause.

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

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

Any action required to be taken at any annual or special meeting of the
stockholders of the Corporation, or any action which may be taken at any annual
or special meeting of the stockholders or otherwise, may not be taken without a
meeting, prior notice and a vote, and stockholders may not act by written
consent.

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

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

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

Eleventh: No director shall be personally liable to the Corporation or its
stockholders for monetary damages for any breach of fiduciary duty by such
director as a director, except (i) for breach of the director's duty of loyalty
to the Corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) pursuant to Section 174 of the Delaware General Corporation Law, or (iv)
for any transaction from which the director derived an improper personal
benefit. No amendment to or repeal of this Article Eleventh shall apply to or
have any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment or repeal.

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

                                       36


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

In Witness Whereof, this Restated Certificate of Incorporation, which restates
and integrates and does not further amend the provisions of the Corporation's
Certificate of Incorporation, as heretofore amended and supplemented, there
being no discrepancies between those provisions and the provisions of this
Restated Certificate of Incorporation, and having been duly adopted by the Board
of Directors of the Corporation in accordance with the provisions of Section 245
of the General Corporation Law of the State of Delaware, has been executed on
the 1st day of September, 1996.
