      PITTSBURGH, January 22, 1999 -- USX-U. S. Steel Group

(NYSE: X) reported fourth quarter 1998 adjusted net income of

$59 million, or 63 cents per diluted share, compared to $141

million, or $1.52 per diluted share in the fourth quarter

1997.  Revenues were $1.4 billion in fourth quarter 1998

compared to $1.8 billion in the same period of 1997.

      U. S. Steel Group recorded fourth quarter 1998 net

income of $76 million, or 81 cents per diluted share.

Results included a $23 million aftertax reduction to interest

expense as a result of adjusting the carrying value of

indexed debt (see note 2 to the attached U. S. Steel Group

statement of operations), partially offset by a $6 million

aftertax charge related to a voluntary early retirement

program.  Fourth quarter 1997 net income of $152 million, or

$1.64 per diluted share, included a gain on the sale of a

plate mill and a reduction to interest expense related to

indexed debt.  The favorable aftertax effect of these special

items was $11 million.

      Fourth quarter 1998 segment income for U. S. Steel

operations was $29 million, or $ 12 per ton, which included a

$10 million pretax charge related to a voluntary early

retirement program.  Fourth quarter 1997 income for U. S.

Steel operations was $208 million, or $70 per ton, which

included a $15 million gain on the sale of a plate mill.

Fourth quarter 1998 results were negatively impacted by the

combined effects of a dramatic increase in imported steel and

the decline in demand for tubular products, resulting in

lower average realized prices and a 21 percent decline in U.

S. Steel's fourth quarter shipments.  Shipments in fourth

quarter 1998 were 2.3 million net tons, compared to 3.0

million net tons in fourth quarter 1997. In response to

market conditions, operating levels were reduced to a less

efficient 76 percent of raw steel capability in fourth

quarter 1998, versus 99 percent in the comparable 1997

quarter.

      For the year 1998, U. S. Steel Group net income

adjusted for special items was $315 million, or $3.40 per

diluted share, compared to $417 million, or $4.51 per diluted

share in 1997.  Revenues in 1998 were $6.3 billion compared

with $6.9 billion in 1997.

      For the year 1998, the U. S. Steel Group recorded net

income of $364 million, or $3.92 per diluted share, which

included the following special items:  favorable effects of

indexed debt adjustments; blast furnace insurance litigation

recoveries; a favorable foreign tax adjustment; and a charge

for the voluntary early retirement program.  The net

favorable aftertax effect of these special items was $49

million.  For the year 1997, the U. S. Steel Group recorded

net income of $452 million, or $4.88 per diluted share, which

included the following special items: blast furnace insurance

recoveries; a gain on the plate mill sale; favorable effects

of indexed debt adjustments; and unfavorable environmental

accrual adjustments.  The net favorable aftertax effect of

these special items was $35 million.

      Segment income for l998 for U. S. Steel operations was

$330 million, or $31 per ton, on shipments of 10.7 million

net tons.  These results included approximately $30 million

for the blast furnace insurance litigation recoveries and a

$10 million charge for the voluntary early retirement

program.  This compares with 1997 income for U. S. Steel

operations of $618 million, or $53 per ton, on shipments of

11.6 million net tons.  These 1997 results included $40

million in blast furnace insurance recoveries, a $15 million

gain on the plate mill sale, and a net charge of $9 million

for environmental accrual adjustments.

      Commenting on the l998 results, USX Board Chairman

Thomas J. Usher said, "During the first half of l998, the U.

S. Steel Group achieved solid financial results comparable to

the record 1997 pace.  However, in mid-l998 imported steel,

including unprecedented volumes at predatory prices, began

flooding U. S. markets.  As a result, the Group's shipments,

average steel prices and operating levels suffered

dramatically throughout the remainder of the year."

      In an attempt to stem the tide of imports, U. S. Steel

joined an industry-labor coalition and filed trade cases for

hot rolled products against Japan, Russia and Brazil in

September.  "As a result of this action," added Usher, "the

U. S. International Trade Commission (ITC), in its

preliminary determination, found the domestic steel industry

was being threatened with material injury as a result of

imports of hot-rolled carbon sheet products from these three

countries.  This preliminary determination of injury is

subject to further investigation by the ITC and U.S.

Department of Commerce.  In addition, the Department of

Commerce is expected to announce its preliminary

determination on anti-dumping duties on February 12, l999."

      In early January 1999, the Clinton Administration sent

a congressionally mandated report to Congress outlining its

plan for responding to the increase in steel imports.  "Unfortunately,

the Administration's Plan was extremely disappointing and fell

far short of what will be required to rectify the import

crisis and the extreme hardship it is imposing on the

domestic steel industry, its workers and their communities,"

said Usher.  "Through the coalition, we will continue to work

with the Administration and Congress in seeking immediate

actions to restore fair trade."

      Added Usher, "The flood of imports caused U. S. Steel

to curtail production to less efficient levels at all

locations in the fourth quarter.  One blast furnace remained

idle at Gary Works.  Raw steel production at the Mon Valley

and Fairfield Works continued at levels well below

capability.  In addition, sections of the plant were idled at

Fairless Works and one of five taconite pellet production

lines in Minnesota was idled."

      To reduce costs, a voluntary early retirement program

was offered to certain nonunion employees in November.  Based

on the acceptance by approximately 400 employees, a $10

million pretax charge was recorded in fourth quarter 1998

results.  Most of the retirements will occur by March 31,

1999.

      Looking ahead, Usher said, "It is uncertain at this

time how soon the import crisis will be resolved.  Steel

consumption in the U.S. remains strong entering 1999.  With

current world conditions, the import problem is far broader

than hot-rolled products from three countries and we continue

to evaluate new trade cases against these and other nations

covering a number of products."

The following notes are an integral part of this financial statement.

                 U. S. STEEL GROUP OF USX CORPORATION
                 SELECTED NOTES TO FINANCIAL STATEMENT
                --------------------------------------


1.The statement of operations of the U. S. Steel Group includes the
  results of operations for the businesses of USX other than
  businesses included in the Marathon Group and a portion of USX's
  net financial costs, general and administrative costs and income
  taxes attributed to the groups in accordance with USX's accounting
  and tax allocation policies.  This statement should be read in
  connection with the consolidated statement of operations of USX.

2.In December 1996, USX issued $117 million of debt (notes) indexed
  to the common stock price of RTI International Metals, Inc. (RTI)
  (formerly RMI Titanium Company).  At maturity in February 2000, USX
  must exchange these notes for shares of RTI common stock, or redeem
  the notes for the equivalent amount of cash.  Since USX's
  investment in RTI is attributed to the U. S. Steel Group, the
  indexed debt is also attributed to the U. S. Steel Group.

  Generally accepted accounting principles require that indexed debt
  be reported at the settlement value.  Quarterly adjustments to the
  carrying value of this indexed debt result in noncash charges or
  credits to interest and other financial costs.

  Net interest and other financial costs included credits of $37
  million and $4 million in the fourth quarter of 1998 and 1997,
  respectively, as a result of the quarterly adjustments in the
  carrying value of indexed debt.  For the years 1998 and 1997, such
  adjustments were credits of $44 million and $10 million,
  respectively.

  USX holds a 26% interest in RTI and accounts for this investment
  under the equity method of accounting.  Changes in the market value
  of USX's investment in RTI generally offset changes in the
  settlement value of the indexed debt.  However, under the equity
  method of accounting, USX cannot recognize in income these
  corresponding changes in the market value of its investment in RTI.
  Such changes will be realized upon disposition of this investment.

  The charges or credits to income resulting from indexed debt
  adjustments affect the comparability of financial results from
  period to period.  Therefore, USX discusses separately the effects
  of indexed debt adjustments on financial results.  In management's
  opinion, the effects of such adjustments should be considered
  separately when evaluating financial performance.

The following notes are an integral part of this financial statement.

                    USX CORPORATION AND SUBSIDIARY COMPANIES
                      SELECTED NOTES TO FINANCIAL STATEMENT
                    ----------------------------------------
1. In August 1998, Marathon Oil Company (Marathon) acquired Tarragon Oil and
   Gas Limited (Tarragon), a Canadian oil and gas exploration and production
   company, for $1.1 billion.  Securityholders of Tarragon received, at their
   election, Cdn$14.25 for each Tarragon share, or the economic equivalent in
   Exchangeable Shares of an indirect Canadian subsidiary of Marathon, which
   are exchangeable solely on a one-for-one basis into USX-Marathon Group
   Common Stock.  The purchase price included cash payments of $686 million,
   issuance of approximately 878,000 Exchangeable Shares valued at $29 million
   and the assumption of $345 million in debt.  USX accounted for the
   acquisition using the purchase method of accounting.  Results of operations
   include the operations of Marathon Canada Limited, formerly known as
   Tarragon, commencing August 12, 1998.

   During 1997, Marathon and Ashland Inc. (Ashland) agreed to combine the major
   elements of their refining, marketing and transportation (RM&T) operations.
   On January 1, 1998, Marathon transferred certain RM&T net assets to Marathon
   Ashland Petroleum LLC (MAP), a new consolidated subsidiary.  Also on January
   1, 1998, Marathon acquired certain RM&T net assets from Ashland in exchange
   for a 38% interest in MAP.  The acquisition was accounted for under the
   purchase method of accounting.  The purchase price was determined to be
   $1.9 billion, based upon an external valuation.  The change in Marathon's
   ownership interest in MAP resulted in a gain of $245 million, which is
   included in 1998 revenues.

2. Effective October 31, 1997, USX sold its stock in Delhi Gas Pipeline
   Corporation and other subsidiaries of USX that comprised all of the Delhi
   Group.  The 1997 financial results of the Delhi Group have been reclassified
   as discontinued operations in the Consolidated Statement of Operations.

3. When USX acquired Marathon in March 1982, crude oil and refined product
   prices were at historically high levels.  USX established a new LIFO cost
   basis for Marathon's inventories by reference to these prices.

   Generally accepted accounting principles require that inventories be
   reported at the lower of recorded cost or current market value.  Marathon
   has established an inventory market valuation (IMV) reserve to reduce the
   cost basis of its inventories to current market value.  Quarterly
   adjustments to the IMV reserve result in noncash charges or credits to
   income from operations.  Decreases in market prices below the cost basis
   result in charges to income from operations.  Once a reserve has been
   established, subsequent increases in prices (up to the cost basis) result in
   credits to income from operations.

   The charges or credits to income resulting from IMV reserve adjustments
   affect the comparability of financial results from period to period.  They
   also affect comparisons with other energy companies, many of which do not
   have such adjustments.  Therefore, USX reports separately the effects of IMV
   reserve adjustments on financial results.  In management's opinion, the
   effects of such adjustments should be considered separately when evaluating
   operating performance.

   When USX acquired the crude oil and refined product inventories associated
   with Ashland's RM&T operations in January 1998, a new cost basis was
   established for those inventories.  The acquisition cost of these
   inventories lowered the overall average cost of the combined RM&T
   inventories; as a result, the price threshold at which an IMV reserve will
   be recorded has also been lowered.  This acquisition resulted in a one-time
   reduction in the IMV reserve, yielding a net favorable IMV reserve
   adjustment in the first quarter of 1998.

                SELECTED NOTES TO FINANCIAL STATEMENT (Continued)
                -------------------------------------------------


4. In December 1996, USX issued $117 million of debt (notes) indexed to the
   common stock price of RTI International Metals, Inc. (RTI) (formerly RMI
   Titanium Company).  At maturity in February 2000, USX must exchange these
   notes for shares of RTI common stock, or redeem the notes for the equivalent
   amount of cash.  Since USX's investment in RTI is attributed to the U. S.
   Steel Group, the indexed debt is also attributed to the U. S. Steel Group.

   Generally accepted accounting principles require that indexed debt be
   reported at the settlement value.  Quarterly adjustments to the carrying
   value of this indexed debt result in noncash charges or credits to interest
   and other financial costs.

   Net interest and other financial costs included credits of $37 million and
   $4 million in the fourth quarter of 1998 and 1997, respectively, as a result
   of the quarterly adjustments in the carrying value of indexed debt.  For the
   years 1998 and 1997, such adjustments were credits of $44 million and $10
   million, respectively.

   USX holds a 26% interest in RTI and accounts for this investment under the
   equity method of accounting.  Changes in the market value of USX's
   investment in RTI generally offset changes in the settlement value of the
   indexed debt.  However, under the equity method of accounting, USX cannot
   recognize in income these corresponding changes in the market value of its
   investment in RTI.  Such changes will be realized upon disposition of this
   investment.

   The charges or credits to income resulting from indexed debt adjustments
   affect the comparability of financial results from period to period.
   Therefore, USX discusses separately the effects of indexed debt adjustments
   on financial results.  In management's opinion, the effects of such
   adjustments should be considered separately when evaluating financial
   performance.
