      PITTSBURGH, October 22, 1998 -- Impacted by an

unprecedented surge in imports, weak tubular markets and

effects of the General Motors strike, USX-U. S. Steel Group

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

$58 million, or 63 cents per diluted share, on revenues of

$1.5 billion.  Third quarter 1997 adjusted net income was

$100 million, or $1.08 per diluted share on revenues of $1.7

billion.

      U. S. Steel Group recorded third quarter 1998 net

income of $65 million, or 71 cents per diluted share,

including a $7 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).  Third quarter 1997 net income was $116 million,

or $1.25 per diluted share, which included $16 million

(aftertax) in insurance proceeds related to the 1996 hearth

breakout at the Gary (Ind.) Works No. 13 blast furnace.

      Income from operations in the third quarter was $105

million, or $41 per ton, on shipments of 2.6 million net

tons.  Income from operations in the third quarter 1997 was

$197 million, or $69 per ton, which included $25 million in

insurance proceeds related to the Gary Works No. 13 blast

furnace.  Shipments were 2.9 million net tons in third

quarter 1997.

      Commenting on the latest quarter's results, USX Board

Chairman Thomas J. Usher said, "After achieving our best year

ever in 1997 and a solid first half this year, the positive

momentum we had built has been interrupted by record volumes

of foreign steel imports at predatory prices, in clear

violation of our trade laws.  This has resulted in lower

shipment levels, lower average steel product prices and less

efficient operating levels."  The surge in imports

contributed to third quarter 1998 raw steel capability

utilization falling to 84.6 percent from 90.4 percent in

third quarter 1997.

      In response to the difficult market conditions,

U. S. Steel Group has curtailed its production operations by

about 15 percent.  "Actions taken to date have included

keeping Gary Works No. 6 blast furnace out of service even

though a scheduled reline was completed in mid-August," added

Usher.  "We also have cut back raw steel production at our

Mon Valley Works and Fairfield Works, suspended one of

Minntac's five taconite pellet production lines in Minnesota,

and taken the Fairfield pipe mill down for several multiple-

week periods."

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

joined with 11 other producers and the United Steelworkers of

America on September 30, 1998 to file trade cases against

Japan, Russia and Brazil.  These filings document that

millions of tons of unfairly traded hot-rolled carbon sheet

products have caused serious injury to the domestic steel

industry through rapidly falling prices and lost business.

Information is continuing to be evaluated and the filing of

additional trade cases is anticipated.

      During the quarter, U. S. Steel Clairton Works became

the first plant in the domestic steel or coking industries to

achieve ISO 14001 certification -- the global benchmark for

environmental management systems.  "The hard work and

dedication of our people to sound environmental performance,

coupled with substantial capital investments by the company,

have made Clairton the industry leader in productivity,

efficiency and environmental excellence," said Usher.

                 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 a credit of $11
  million and $7 million in the third quarter and nine months of
  1998, respectively, and a credit of $6 million in the 1997 nine
  months, as a result of the quarterly adjustments in the carrying
  value of indexed debt.  There was no adjustment in the third
  quarter of 1997.

  USX holds a 27% 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.

                    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 of $1.1 billion included cash payments to
   Tarragon securityholders of $670 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.  Tarragon operations have been included in USX's results of
   operations 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 the first nine months of 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 a credit of $11 million and
   $7 million in the third quarter and nine months of 1998, respectively, and a
   credit of $6 million in the 1997 nine months, as a result of the quarterly
   adjustments in the carrying value of indexed debt.  There was no adjustment
   in the third quarter of 1997.

   USX holds a 27% 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.
