      PITTSBURGH, January 24, 2001 -- USX-U. S. Steel Group (NYSE: X) reported a

fourth quarter 2000 adjusted net loss of $57 million, or 67 cents per diluted

share, compared with net income of $39 million, or 42 cents per diluted share in

fourth quarter 1999.  Revenues were $1.4 billion in fourth quarter 2000,

compared with $1.5 billion in the same period of 1999.

      U. S. Steel Group recorded a fourth quarter 2000 net loss of $139 million,

or $1.59 per diluted share, which included an after-tax total of $82 million for

unfavorable special items.  These items included $46 million for asset

impairments at two coal mines, $22 million to establish a reserve against notes

and receivables from financially distressed steel companies, and $14 million for

environmental accruals.  The fourth quarter 2000 net loss reflects an unusually

high state tax provision because it was determined that certain previously

recorded state tax

                                      -2-

benefits can no longer be utilized.

      Fourth quarter 1999 net income of $34 million, or 35 cents per diluted

share, included special items which had a net unfavorable after-tax effect of $5

million.

      In the fourth quarter 2000, U. S. Steel Group's Domestic Steel segment

recorded a loss from operations of $122 million, including pre-tax charges of

$55 million for reserves against notes and receivables, and environmental

accruals, resulting in an adjusted loss of $29 per ton. U. S. Steel

Kosice s.r.o. (USSK), the Slovak Republic steel operation, reported fourth

quarter 2000 segment income of $2 million, or $6 per ton, following its

acquisition by USX on November 24, 2000.

      Fourth quarter 1999 segment income for Domestic Steel was $48 million, or

$17 per ton, which included unfavorable special items totaling $7 million pre-

tax.

      Fourth quarter 2000 results were negatively impacted by significantly

reduced shipment levels and prices, inefficient operating rates due to lower

volumes, higher energy costs and severely limited coal mining operations due to

adverse geological conditions at two mines.  Tubular shipments and prices

continued to benefit from strong energy markets.

      Total shipments for Domestic Steel in fourth quarter 2000 were 2.3 million

net tons, down 19 percent from fourth quarter 1999 shipments of 2.9 million net

tons and the lowest level since the first quarter 1993.  Total shipments for

USSK in the 38 days of operation under USX ownership in the fourth quarter 2000

were 317 thousand net tons.

      Domestic raw steel capability utilization in the fourth quarter of 2000

was 75 percent, down from 97 percent in fourth quarter 1999.  USSK raw steel

capability utilization in the period following the November 24,

                                    -3-

2000 acquisition was 80 percent.

      For the year 2000, U. S. Steel Group net income adjusted for special items

was $77 million, or 78 cents per diluted share, compared with $83 million, or 84

cents per diluted share in 1999.  Revenues in 2000 were $6.1 billion, compared

with $5.5 billion in 1999.

      For the year 2000, the U. S. Steel Group recorded a net loss of $21

million, or 33 cents per diluted share, which included special items with a net

unfavorable after-tax effect of $98 million or $1.11 per diluted share.  In

addition to those items mentioned for the fourth quarter 2000, special items

also included other environmental and legal accruals and USX's share of

restructuring and impairment charges at Republic Technologies International, LLC

(Republic).

      For the year 1999, U. S. Steel Group recorded net income of $44 million,

or 40 cents per diluted share, which included special items having a net

unfavorable after-tax effect of $39 million, or 44 cents per share.

      Segment income in 2000 for Domestic Steel was $23 million, or $2 per ton,

on shipments of 10.8 million net tons, which included unfavorable pre-tax

special items totaling $151 million, or $14 per ton.  Segment income in 1999 for

Domestic Steel was $91 million, or $9 per ton, on shipments of 10.6 million net

tons.  These 1999 results included $24 million, or $2 per ton, of unfavorable

pre-tax special items.  Domestic raw steel capability utilization in 2000 was 89

percent, down from 94 percent in 1999.

      The decrease in the Domestic Steel segment income was the result of lower

sheet product shipment volumes, higher costs due to lower throughput, higher

energy prices and problems in coal operations.

      Commenting on these results, Thomas J. Usher, USX Corporation

                                   -4-

Board Chairman, said, "The U. S. Steel Group's results for the fourth quarter

were disappointing.  The devastating combination of continued high steel import

levels and a slowing domestic economy resulted in significantly reduced order

levels, operating rates and shipments and sheet prices that were among the

lowest in the past twenty years.  The increasing list of steel bankruptcy

filings and reports of tight liquidity among other steel competitors demonstrate

the severity of the steel crisis in this country."

      Usher added, "Import levels in 2000 approached the record levels of 1998.

Due to the latest surge in imports, fourth quarter 2000 domestic raw steel

production declined 23 percent from the prior year's fourth quarter,

necessitating layoffs and idling of production facilities at a number of

locations."

      Responding to the latest import crisis, U. S. Steel participated in

November with an industry group in filing trade cases against dumped and

subsidized imports of hot-rolled carbon steel from ll countries.  In late

December, the U.S. International Trade Commission (ITC) issued a unanimous

preliminary determination that there is a reasonable indication that these

imports were materially injuring the domestic industry.  This preliminary

determination is subject to further investigation and review by the ITC and the

U.S. Department of Commerce.

      Regarding the coal mining problems, adverse geological conditions were

encountered during the fourth quarter at U. S. Steel Mining's coal mines in

Alabama and West Virginia.  As a result, "force majeure" provisions in coal

supply contracts were exercised and, following a reassessment of long-term

prospects, asset impairments for both mines were recorded.

      U. S. Steel's purchase of LTV Corporation's tin mill products

                                   -5-

business has been delayed as a result of LTV's filing for Chapter ll

bankruptcy protection in late December.  Assuming the bankruptcy court

approves this non-cash transaction, an orderly transition in ownership is

expected.

      Looking ahead, Usher noted, "The USSK acquisition is a major step in our

globalization strategy.  Many of our American customers are moving abroad, and a

number of them have already located facilities in Central Europe where demand

for consumer goods is increasing.  Through USSK, we are now strategically

positioned to service the growing needs of these and other customers in this

region."

      In addition, Usher said, "Entering 2001, the outlook is far from

promising, especially for the first quarter.  Although we anticipate that first

quarter domestic shipments will be somewhat better than fourth quarter levels,

we expect that sheet and plate pricing, which declined markedly in the fourth

quarter, will continue to be depressed.  Steel imports are continuing at high

levels across all product lines.  Domestically, our order book continues to be

weak, the economy continues to soften and natural gas prices remain

extraordinarily high.  We are optimistic, however, that USSK should have a

favorable impact on our 2001 results.  Our tubular business is strong and, as

excess inventory levels for other products are drawn down, we expect to see

improvements in both shipments and prices as the year progresses."

      For the full year 2001, domestic shipments are expected to be

approximately 11 million net tons, excluding any shipments from the potential

acquisition of LTV Tin.  USSK shipments for the full year 2001 are expected to

be approximately 3.3 million to 3.6 million net tons.

                                      *****

      This release contains forward-looking statements with respect to

                                      -6-

shipments, prices, the impact of USSK and the acquisition of LTV Corporation's

tin operations.  Some factors, among others, that could affect first quarter and

full year 2001 shipments and prices include import levels, customer inventory

levels and U.S. economic performance.  Some factors, among others, that could

affect full year 2001 shipments and the overall impact from USSK may be

unfavorable European economic conditions and currency exchange rate

fluctuations.  One factor which could affect the acquisition of LTV

Corporation's tin operations is bankruptcy court approval.  In accordance with

"safe harbor" provisions of the Private Securities Litigation Reform Act of

1995, USX has included in Form 10-K for the year ended December 31, 1999, and

subsequent Form 10-Q's and Form 8-K's, cautionary statements identifying

important factors, but not necessarily all factors, that could cause actual

results to differ materially from those set forth in the forward-looking

statements.

      A Statement of Operations and Preliminary Supplemental Statistics for the

U. S. Steel Group and a Consolidated Statement of Operations for USX Corporation

are attached.

                 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 1999, USX irrevocably deposited with a trustee the entire 5.5
   million common shares it owned in RTI International Metals (RTI).  The
   deposit of the shares resulted in the satisfaction of USX's obligation
   under its 6-3/4% Exchangeable Notes (indexed debt) due February 1,
   2000.  Under the terms of the indenture, the trustee exchanged one RTI
   share for each note at maturity; therefore, none reverted back to USX.

   As a result of the above transaction, USX recorded in the first
   quarter of 1999 an extraordinary loss of $5 million, net of a $3
   million income tax benefit, representing prepaid interest expense
   and the write-off of unamortized debt issue costs, and a pretax
   charge of $22 million, representing the difference between the
   carrying value of the investment in RTI and the carrying value of
   the indexed debt, which is included in net gains on disposal of
   assets.

   Additionally, a $13 million credit to adjust the indexed debt to
   settlement value at March 31, 1999, is included in net interest
   and other financial costs.

   In December 1996, USX had issued the $117 million of notes indexed
   to the common share price of RTI.  At maturity, USX would have
   been required to exchange the notes for shares of RTI common
   stock, or redeem the notes for the equivalent amount of cash.
   Since USX's investment in RTI was attributed to the U. S. Steel
   Group, the indexed debt was also attributed to the U. S. Steel
   Group.  USX had a 26% investment in RTI and accounted for its
   investment using the equity method of accounting.

   Republic Technologies International, LLC, an equity method
   affiliate of USX, recorded in the third quarter of 1999 an
   extraordinary loss related to the early extinguishment of debt.
   As a result, the U. S. Steel Group recorded an extraordinary loss
   of $2 million, net of a $1 million income tax benefit,
   representing its share of the extraordinary loss.

3. In August 1999, USX and Kobe Steel, Ltd. (Kobe Steel) completed a
   transaction that combined the steelmaking and bar producing assets
   of USS/Kobe Steel Company (USS/Kobe) with companies controlled by
   Blackstone Capital Partners II.  The combined entity was named
   Republic Technologies International, LLC (Republic).  As a result
   of this transaction, the U. S. Steel Group recorded $47 million in
   charges related to the impairment of the carrying value of its
   investment in USS/Kobe and costs related to the formation of
   Republic.  These charges were included in loss from investees in
   1999.  In addition, USX made a $15 million equity investment in
   Republic.  USX owned 50% of USS/Kobe and now owns 16% of Republic.
   USX accounts for its investment in Republic under the equity
   method of accounting. The seamless pipe business of USS/Kobe was
   excluded from this transaction.  That business, now known as
   Lorain Tubular Company LLC, is a wholly owned subsidiary of USX.

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


4. In the fourth quarter 2000, the U. S. Steel Group adopted the
   following accounting pronouncements primarily related to the
   classification of items in the statement of operations.  In
   December 1999, the Securities and Exchange Commission (SEC) issued
   Staff Accounting Bulletin No. 101 (SAB 101) "Revenue Recognition
   in Financial Statements," which summarizes the SEC staff's
   interpretations of generally accepted accounting principles
   related to revenue recognition and classification.  During the
   third quarter 2000, the Emerging Issues Task Force of the
   Financial Accounting Standards Board (EITF) issued EITF Consensus
   No. 99-19 "Reporting Revenue Gross as a Principal versus Net as an
   Agent", which addresses whether certain cost items should be
   reported as a reduction of revenue or as a component of cost of
   sales, and EITF Consensus No. 00-10 "Accounting for Shipping and
   Handling Fees and Costs," which addresses the classification of
   costs incurred for shipping goods to customers.  The adoption of
   these new pronouncements had no net effect on the financial
   position or results of operations of the U. S. Steel Group,
   although they required reclassifications of certain amounts in the
   statement of operations.

5. In November 2000, USX acquired U. S. Steel Kosice s.r.o. (USSK),
   which is located in the Slovak Republic.  USSK was formed to hold
   the steel operations and related assets of VSZ a.s (VSZ), a
   diversified Slovak corporation.  The cash purchase price was $69
   million.  Additional payments to VSZ of not less than $25 million
   and up to $75 million are contingent upon the future performance
   of USSK.  Additionally, $325 million of debt was included with the
   acquisition.  The acquisition was accounted for under the purchase
   method of accounting.  The 2000 results of operations include the
   operations of USSK commencing November 24, 2000.

   Prior to this transaction, USX and VSZ were equal partners in VSZ
   U. S. Steel s.r.o. (VSZUSS), a tin mill products manufacturer.
   The assets of USSK included VSZ's interest in VSZUSS.  The
   acquisition of the remaining interest in VSZUSS was accounted for
   under the purchase method of accounting.  Previously, USX had
   accounted for its investment in VSZUSS under the equity method of
   accounting.

The following notes are an integral part of this financial statement.
               USX CORPORATION AND SUBSIDIARY COMPANIES
                 SELECTED NOTES TO FINANCIAL STATEMENT
               ----------------------------------------


1. 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.

2. In 1999, USX irrevocably deposited with a trustee the entire 5.5
   million common shares it owned in RTI International Metals (RTI).
   The deposit of the shares resulted in the satisfaction of USX's
   obligation under its 6-3/4% Exchangeable Notes (indexed debt) due
   February 1, 2000.  Under the terms of the indenture, the trustee
   exchanged one RTI share for each note at maturity; therefore, none
   reverted back to USX.

   As a result of the above transaction, USX recorded in the first
   quarter of 1999 an extraordinary loss of $5 million, net of a $3
   million income tax benefit, representing prepaid interest expense
   and the write-off of unamortized debt issue costs, and a pretax
   charge of $22 million, representing the difference between the
   carrying value of the investment in RTI and the carrying value of
   the indexed debt, which is included in net gains (losses) on
   disposal of assets.

   Additionally, a $13 million credit to adjust the indexed debt to
   settlement value at March 31, 1999, is included in net interest
   and other financial costs.

   In December 1996, USX had issued the $117 million of notes indexed
   to the common share price of RTI.  At maturity, USX would have
   been required to exchange the notes for shares of RTI common
   stock, or redeem the notes for the equivalent amount of cash.
   Since USX's investment in RTI was attributed to the U. S. Steel
   Group, the indexed debt was also attributed to the U. S. Steel
   Group.  USX had a 26% investment in RTI and accounted for its
   investment using the equity method of accounting.

   Republic Technologies International, LLC, an equity method
   affiliate of USX, recorded in the third quarter of 1999 an
   extraordinary loss related to the early extinguishment of debt.
   As a result, USX recorded an extraordinary loss of $2 million, net
   of a $1 million income tax benefit, representing its share of the
   extraordinary loss.

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


3. In August 1999, USX and Kobe Steel, Ltd. (Kobe Steel) completed a
   transaction that combined the steelmaking and bar producing assets
   of USS/Kobe Steel Company (USS/Kobe) with companies controlled by
   Blackstone Capital Partners II.  The combined entity was named
   Republic Technologies International, LLC (Republic).  As a result
   of this transaction, USX recorded $47 million in charges related
   to the impairment of the carrying value of its investment in
   USS/Kobe and costs related to the formation of Republic.  These
   charges were included in dividend and investee income (loss) in
   1999.  In addition, USX made a $15 million equity investment in
   Republic.  USX owned 50% of USS/Kobe and now owns 16% of Republic.
   USX accounts for its investment in Republic under the equity
   method of accounting. The seamless pipe business of USS/Kobe was
   excluded from this transaction.  That business, now known as
   Lorain Tubular Company LLC, is a wholly owned subsidiary of USX.

4. In the fourth quarter 2000, Marathon exchanged its 37.5 percent
   interest in Sakhalin Energy Investment Company Ltd. (Sakhalin
   Energy) for certain interests in the UK Atlantic Margin area and
   the U.S. Gulf of Mexico as well as reimbursement for all Sakhalin
   project capital expenditures made in 2000.  As a result of the
   absence of future foreign source income from Sakhalin Energy, an
   additional valuation allowance of $235 million to reduce deferred
   federal tax benefits was recognized in the third quarter 2000.

5. In the fourth quarter 2000, USX adopted the following accounting
   pronouncements primarily related to the classification of items in
   the statement of operations.  In December 1999, the Securities and
   Exchange Commission (SEC) issued Staff Accounting Bulletin No. 101
   (SAB 101) "Revenue Recognition in Financial Statements," which
   summarizes the SEC staff's interpretations of generally accepted
   accounting principles related to revenue recognition and
   classification.  During the third quarter 2000, the Emerging
   Issues Task Force of the Financial Accounting Standards Board
   (EITF) issued EITF Consensus No. 99-19 "Reporting Revenue Gross as
   a Principal versus Net as an Agent", which addresses whether
   certain cost items should be reported as a reduction of revenue or
   as a component of cost of sales, and EITF Consensus No. 00-10
   "Accounting for Shipping and Handling Fees and Costs," which
   addresses the classification of costs incurred for shipping goods
   to customers.  The adoption of these new pronouncements had no net
   effect on the financial position or results of operations of USX,
   although they required reclassifications of certain amounts in the
   statement of operations.

6. In November 2000, USX acquired U. S. Steel Kosice s.r.o. (USSK),
   which is located in the Slovak Republic.  USSK was formed to hold
   the steel operations and related assets of VSZ a.s (VSZ), a
   diversified Slovak corporation.  The cash purchase price was $69
   million.  Additional payments to VSZ of not less than $25 million
   and up to $75 million are contingent upon the future performance
   of USSK.  Additionally, $325 million of debt was included with the
   acquisition.  The acquisition was accounted for under the purchase
   method of accounting.  The 2000 results of operations include the
   operations of USSK commencing November 24, 2000.

   Prior to this transaction, USX and VSZ were equal partners in VSZ
   U. S. Steel s.r.o. (VSZUSS), a tin mill products manufacturer.
   The assets of USSK included VSZ's interest in VSZUSS.  The
   acquisition of the remaining interest in VSZUSS was accounted for
   under the purchase method of accounting.  Previously, USX had
   accounted for its investment in VSZUSS under the equity method of
   accounting.

7. In December 2000, Marathon and Kinder Morgan Energy Partners, L.P.
   signed a definitive agreement to form a joint venture combining
   certain of their oil and gas producing activities in the U.S.
   Permian Basin, including Marathon's interest in the Yates Field.
   This transaction will allow Marathon to expand its interests in
   the Permian Basin and will improve access to materials for use in
   enhanced recovery techniques in the Yates Field.  The joint
   venture named MKM Partners L.P., commenced operations in January
   2001 and will be accounted for under the equity method of
   accounting.  Marathon recognized a pretax charge of $931 million
   in the fourth quarter 2000, related to the joint venture
   formation.
