               SELECTED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
               ---------------------------------------------------
                                   (Unaudited)

                                        
 1.  The information furnished in these financial statements is unaudited but,
    in the opinion of management, reflects all adjustments necessary for a fair
    presentation of the results for the periods covered.  All such adjustments
    are of a normal recurring nature unless disclosed otherwise.  These
    financial statements, including selected notes, have been prepared in
    accordance with the applicable rules of the Securities and Exchange
    Commission and do not include all of the information and disclosures
    required by generally accepted accounting principles for complete financial
    statements.  Additional information is contained in the USX Annual Report
    on Form 10-K for the year ended December 31, 1993.  Financial data for the
    first nine months of 1993 has been restated to reflect the adoption of
    Statement of Financial Accounting Standards No. 112, "Employers' Accounting
    for Postemployment Benefits" (SFAS No. 112), and Emerging Issues Task Force
    Consensus No. 93-14, "Accounting for Multiple-Year Retrospectively Rated
    Insurance Contracts" (EITF No. 93-14) (see Note 11).

 2.  The method of calculating net income (loss) per share for the Marathon
     Stock, Steel Stock and Delhi Stock reflects the USX Board of Directors'
     intent that the separately reported earnings and surplus of the Marathon
     Group, the U. S. Steel Group and the Delhi Group, as determined consistent
     with the USX Certificate of Incorporation, are available for payment of
     dividends to the respective classes of stock, although legally available
     funds and liquidation preferences of these classes of stock do not
     necessarily correspond with these amounts.  The financial statements of the
     Marathon Group, the U. S. Steel Group and the Delhi Group, taken together,
     include all accounts which comprise the corresponding consolidated
     financial statements of USX.

     Primary net income (loss) per share is calculated by adjusting net income
     (loss) for dividend requirements of preferred stock and, in the case of
     Delhi Stock, for the income (loss) applicable to the Retained Interest; and
     is based on the weighted average number of common shares outstanding plus
     common stock equivalents, provided they are not antidilutive.  Common stock
     equivalents result from assumed exercise of stock options and surrender of
     stock appreciation rights associated with stock options, where applicable.

     Fully diluted net income (loss) per share assumes conversion of convertible
     securities for the applicable periods outstanding and assumes exercise of
     stock options and surrender of stock appreciation rights provided, in each
     case, the effect is not antidilutive.

 3.  The items below were included in both sales and operating costs, resulting
     in no effect on income:

     The inventory market valuation reserve reflects the extent that the
     recorded costs of crude oil and refined products inventories exceed net
     realizable value.  The reserve is decreased to reflect increases in market
     prices and inventory turnover and increased to reflect decreases in market
     prices.  Changes in the inventory market valuation reserve resulted in a
     $158 million credit to operating income in the first nine months of 1994
     ($63 million charge in the third quarter) and a $54 million charge against
     operating income in the first nine months of 1993 ($30 million charge in
     the third quarter).

 5.  In the first nine months of 1994, payments of $124 million were made to
     settle various state tax issues.  As a result of these settlements, net
     income in the second quarter of 1994 included a net credit of $37 million,
     consisting of a credit of $12 million in operating costs, a credit of $35
     million in interest and other financial costs and a net income tax
     provision effect of $10 million.

 6.  In the first nine months of 1994, restructuring charges totaling $40
     million were recorded for the write-down of assets to estimated net
     realizable value related to the planned disposition of certain nonstrategic
     gas gathering and processing assets and other investments.  Charges of $37
     million were included in operating costs and $3 million included in other
     income in the second quarter of 1994.

 7.  Pretax income (loss) in the first nine months of 1993 included a $633
     million charge for the Lower Lake Erie Iron Ore Antitrust Litigation
     against a former USX subsidiary, the Bessemer & Lake Erie Railroad (B&LE).
     Charges of $438 million were included in operating costs and $195 million
     ($14 million in the third quarter) included in interest and other financial
     costs. The effect on net income (loss) was $406 million unfavorable ($6.50
     per share of Steel Stock).

 8.  Operating income (loss) included net periodic pension credits of $92
    million and $160 million in the first nine months of 1994 and 1993,
    respectively, ($31 million and $54 million in the third quarter of 1994 and
    1993, respectively). These pension credits are primarily noncash and for
    the most part are included in selling, general and administrative expenses.
    The expected long-term rate of return on plan assets, which is reflected in
    the calculation of net periodic pension credits, was reduced to 9% in 1994
    from 10% in 1993.

 9.  Other income in the first nine months of 1994 included a pretax gain of
    $183 million from disposal of assets ($150 million in the third quarter,
    including the sale of the assets of a retail propane marketing subsidiary).
    Other income in the first nine months of 1993 included a pretax gain of
    $151 million from disposal of assets ($8 million in the third quarter),
    primarily related to the second quarter sale of the Cumberland coal mine.

10.  The provision for estimated income taxes for the periods reported is based
    on tax rates and amounts which recognize management's best estimate of
    current and deferred tax assets and liabilities.

     The provision for the third quarter and first nine months of 1994 included
    a one-time $32 million deferred tax benefit related to the excess of tax
    over financial basis in shares of RMI Titanium Company (RMI), concurrent
    with the adoption of equity accounting for RMI.  The third quarter 1993
    income tax provision included a credit of $64 million related to
    recognition of additional future U.S. income tax benefits for deferred
    foreign income taxes.  This favorable adjustment resulted from USX's
    ability to elect to credit, rather than deduct, foreign income taxes for
    U.S. federal income tax purposes in future periods.  The income tax
    provision for the third quarter of 1993 also included a $24 million charge
    associated with an increase in the federal income tax rate from 34% to 35%.
    This charge reflected a $29 million unfavorable remeasurement of deferred
    federal income tax liabilities as of January 1, 1993, and a $5 million
    favorable effect related to 1993 pretax losses.

11.  In 1993, USX adopted SFAS No. 112 and EITF No. 93-14.  The cumulative
    effect of these changes in accounting principles decreased first quarter
    1993 net income by $86 million, net of $50 million income tax effect, for
    SFAS No. 112; and $6 million, net of $3 million income tax effect, for EITF
    No. 93-14.

12.  In the first quarter of 1994, USX issued $300 million in aggregate
    principal amount of 7.20% Notes Due 2004 and $150 million in aggregate
    principal amount of LIBOR-based Floating Rate Notes Due 1996.  In the first
    quarter of 1994, an aggregate principal amount of $57 million of Marathon's
    7% Monthly Interest Guaranteed Notes Due 2002 was issued in exchange for an
    equivalent principal amount of its 9-1/2% Guaranteed Notes Due 1994.  The
    $642 million balance of Marathon's 9-1/2% Guaranteed Notes Due 1994 was
    paid in the first quarter of 1994.  In the second quarter of 1994, USX
    issued $55 million of 6.70% Environmental Improvement Revenue Refunding
    Bonds due 2020 and 2024 to refinance Environmental Improvement Bonds.

     In the third quarter of 1994, USX entered into a $2.325 billion revolving
     credit agreement which terminates in August 1999.  Interest is based on
     defined short-term market rates.  This agreement replaced $2.0 billion in
     revolving credit agreements.

12.  (Continued)

     At September 30, 1994, USX had no borrowings against the long-term
     revolving credit agreement, but had outstanding borrowings of $33 million
     against short-term lines of credit totaling $165 million, which require
     maintenance of compensating balances of 3%.  At September 30, 1994, $292
     million of commercial paper and certain long-term debt due within one year
     of $401 million was included in long-term debt, since the unused long-term
     credit agreement was available for refinancing, if needed.

     In the event of a change in control of USX, debt obligations totaling
     $3,825 million at September 30, 1994, may be declared immediately due and
     payable.

13.  In the first quarter of 1994, USX sold 5,000,000 shares of Steel Stock to
     the public for net proceeds of $201 million.  In addition, USX Capital LLC,
     a wholly owned subsidiary of USX, sold $250 million of 8-3/4% Cumulative
     Monthly Income Preferred Shares (MIPS).  The financial costs of the MIPS
     are included in interest and other financial costs.

14.  USX has entered into agreements to sell certain accounts receivable subject
     to limited recourse.  Payments are collected from the sold accounts
     receivable; the collections are reinvested in new accounts receivable for
     the buyers; and a yield based on defined short-term market rates is
     transferred to the buyers.  At September 30, 1994, the balance of sold
     accounts receivable that had not been collected was $750 million.  Buyers
     have collection rights to recover payments from an amount of outstanding
     receivables equal to 120% of the outstanding receivables purchased on a
     nonrecourse basis; such overcollateralization cannot exceed $150 million.
     In the event of a change in control of USX, as defined in the agreements,
     USX may be required to forward all payments collected on sold accounts
     receivable to the buyers.

     Prior to 1993, USX Credit, a division of USX, sold certain of its loans
     receivable subject to limited recourse.  USX Credit continues to collect
     payments from the loans and transfer to the buyers principal collected plus
     yield based on defined short-term market rates.  At September 30, 1994, the
     balance of sold loans receivable subject to recourse was $150 million.  As
     of September 30, 1994, USX Credit had outstanding loan commitments of $29
     million.  USX Credit is not actively making new loan commitments.  In the
     event of a change in control of USX, as defined in the agreement, USX may
     be required to provide cash collateral in the amount of the uncollected
     loans receivable to assure compliance with the limited recourse provisions.

15.  USX is the subject of, or a party to, a number of pending or threatened
     legal actions, contingencies and commitments involving a variety of
     matters, including laws and regulations relating to the environment.
     Certain of these matters are discussed below.  The ultimate resolution of
     these contingencies could, individually or in the aggregate, be material to
     the consolidated financial statements.  However, management believes that
     USX will remain a viable and competitive enterprise even though it is
     possible that these contingencies could be resolved unfavorably.  See
     discussion of Liquidity and Capital Resources in USX Consolidation
     Management's Discussion and Analysis of Financial Condition and Results of
     Operations.

15.  (Continued)

     In the first nine months of 1994, USX paid $367 million to settle
     substantially all of the remaining judgments against the B&LE in the Lower
     Lake Erie Iron Ore Antitrust Litigation.  Two remaining plaintiffs in this
     case have had their damage claims remanded for retrial.  A new trial may
     result in awards more or less than the original asserted claims of $8
     million and would be subject to trebling.

     On November 3, 1992, the United States District Court for the District of
    Utah Central Division issued a Memorandum Opinion and Order in Pickering v.
    USX relating to pension and compensation claims by approximately 1,900
    employees of USX's former Geneva (Utah) Works.  Although the court
    dismissed a number of the claims by the plaintiffs, it found that USX had
    violated the Employee Retirement Income Security Act by interfering with
    the accrual of pension benefits of certain employees and amending a benefit
    plan to reduce the accrual of future benefits without proper notice to plan
    participants.  Further proceedings were held to determine damages and,
    pending the court's determinations, USX may appeal.  Plaintiffs' counsel
    has been reported as estimating plaintiffs' anticipated recovery to be in
    excess of $100 million.  USX believes actual damages will be substantially
    less than plaintiffs' estimates.  In the first quarter of 1994, USX entered
    into settlement agreements with 208 plaintiffs providing for releases of
    liability against USX and the aggregate payment of approximately $1 million
    by USX.  An order dismissing these plaintiffs from the case with prejudice
    was entered on May 31, 1994.

     USX is subject to federal, state, local and foreign laws and regulations
    relating to the environment.  These laws generally provide for control of
    pollutants released into the environment and require responsible parties to
    undertake remediation of hazardous waste disposal sites.  Penalties may be
    imposed for noncompliance.  USX provides for remediation costs and
    penalties when the responsibility to remediate is probable and the amount
    of associated costs is reasonably determinable.  Generally, the timing of
    these accruals coincides with completion of a feasibility study or the
    commitment to a formal plan of action.  Estimated abandonment and
    dismantlement costs of offshore production platforms are accrued based upon
    estimated proved oil and gas reserves on a units-of-production method;
    estimated mine reclamation costs are accrued based on actual clean tons of
    coal produced.  At September 30, 1994, accrued liabilities for remediation,
    platform abandonment and mine reclamation totaled $319 million.  It is not
    presently possible to estimate the ultimate amount of all remediation costs
    that might be incurred or the penalties that may be imposed.

     For a number of years, USX has made substantial capital expenditures to
    bring existing facilities into compliance with various laws relating to the
    environment.  In 1993 and 1992, such capital expenditures totaled
    $181 million and $294 million, respectively.  USX anticipates making
    additional such expenditures in the future; however, the exact amounts and
    timing of such expenditures are uncertain because of the continuing
    evolution of specific regulatory requirements.

15.  (Continued)

     By reason of Executive Orders and related regulations under which the U.S.
    Government is continuing economic sanctions against Libya, USX was required
    to discontinue performing its Libyan petroleum contracts on June 30, 1986.
    In June 1989, the Department of the Treasury authorized USX to resume
    performing under those contracts.  Pursuant to that authorization, USX has
    engaged the Libyan National Oil Company and the Secretary of Petroleum in
    continuing negotiations to determine when and on what basis they are
    willing to allow USX to resume realizing revenue from USX's investment of
    $108 million in Libya.  USX is uncertain when these negotiations can be
    completed or how the negotiations will be affected by the United Nations'
    sanctions against Libya.

     Guarantees by USX of the liabilities of affiliated and other entities
     totaled $185 million at September 30, 1994.  In the event that any defaults
     of guaranteed liabilities occur, USX has access to its interest in the
     assets of most of the affiliates to reduce losses resulting from these
     guarantees.  As of September 30, 1994, the largest guarantee for a single
     affiliate was $94 million.

     At September 30, 1994, USX's pro rata share of obligations of LOOP INC. and
     various pipeline affiliates secured by throughput and deficiency agreements
     totaled $196 million.  Under the agreements, USX is required to advance
     funds if the affiliates are unable to service debt.  Any such advances are
     prepayments of future transportation charges.

     At September 30, 1994, contract commitments for capital expenditures for
     property, plant and equipment totaled $309 million compared with $389
     million at December 31, 1993.

                    USX CORPORATION AND SUBSIDIARY COMPANIES
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     The following discussion should be read in conjunction with the third
quarter 1994 USX consolidated financial statements and selected notes.

Results of Operations
- ---------------------
     USX had net income of $191 million in the third quarter of 1994, compared
with restated net income of $63 million in the third quarter of 1993.  For the
first nine months of 1994, USX reported net income of $373 million.  For the
first nine months of 1993, USX reported a net loss of $296 million, as restated
to reflect the unfavorable $92 million cumulative effect of changes in
accounting principles.

     See the Consolidated Statement of Operations - Income per Common Share for
comparative amounts applicable to the three classes of common stock.

     Sales in the third quarter of 1994 totaled $5.1 billion, compared with $4.5
billion in the third quarter of 1993.  The improvement primarily reflected a 17%
increase in sales for the Marathon Group.  Sales in the first nine months of
1994 totaled $14.2 billion, compared with $13.5 billion in the same period in
1993.  The improvement reflected increases of 3%, 9% and 8%, respectively, in
sales for the Marathon Group, the U. S. Steel Group and the Delhi Group.
Matching buy/sell transactions and excise taxes are included in both sales and
operating costs of the Marathon Group, resulting in no effect on operating
income.  Excise taxes increased from $511 million and $1,407 million in the
third quarter and first nine months of 1993, respectively, to $733 million and
$1,878 million in the same periods in 1994.  Higher excise taxes were the
predominant factor in the increase in taxes other than income taxes in both
periods in 1994.

     USX had operating income of $225 million in the third quarter of 1994,
compared with restated operating income of $158 million in the same quarter of
1993.  Third quarter operating income included unfavorable noncash effects of
$63 million in 1994 and $30 million in 1993 resulting from increases in the
inventory market valuation reserve.  Excluding the effects of the changes in the
inventory market valuation reserve, third quarter 1994 operating income improved
$100 million from the third quarter of 1993 due primarily to increases of $66
million and $40 million in operating results for the Marathon Group and the
U. S. Steel Group, respectively.

     USX had operating income of $627 million in the first nine months of 1994,
compared with restated operating income of $28 million in the same period in
1993.    Operating income in the first nine months of 1994 included a $158
million favorable noncash effect resulting from a decrease in the inventory
market valuation reserve, partially offset by restructuring charges of $37
million related to the planned disposition of certain nonstrategic gas gathering
and processing assets.  Operating income in the first nine months of 1993
included a $438 million charge for the Lower Lake Erie Iron Ore Antitrust
Litigation against the Bessemer & Lake Erie Railroad ("B&LE"), a former USX
subsidiary, and a $54 million unfavorable noncash effect resulting from an
increase in the inventory market valuation reserve.  Excluding the effects of
these items, operating income in the first nine months of 1994 decreased $14
million from the same period in 1993 mainly due to lower results for the Delhi
Group, partially offset by higher results for the U. S. Steel Group.

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     Other income in the first nine months of 1994 included a pretax gain of
$183 million from the disposal of assets ($150 million in the third quarter),
primarily reflecting the third quarter sale of the assets of a retail propane
marketing subsidiary and the sale of certain domestic oil and gas production
properties.  Other income in the first nine months of 1993 included a pretax
gain of $151 million from the disposal of assets ($8 million in the third
quarter), including the sales of the Cumberland coal mine and an investment in
an insurance company.  Income from equity affiliates in the third quarter and
first nine months of 1994 improved by $7 million and $36 million, respectively,
from the same periods in 1993.

     Net interest and other financial costs in the first nine months of 1994
included a $35 million favorable effect resulting from settlement of various
state tax issues.  Net interest and other financial costs in the third quarter
and first nine months of 1993 included $14 million and $195 million,
respectively, of interest expense related to the B&LE litigation.

     The provision for estimated income taxes for the periods reported is based
on tax rates and amounts which recognize management's best estimate of current
and deferred tax assets and liabilities.  The income tax provision for the third
quarter and first nine months of 1994 included a one-time $32 million deferred
tax benefit (see Note 10 to the consolidated financial statements).  The third
quarter 1993 income tax provision included a credit of $64 million related to
recognition of additional future U.S. income tax benefits for deferred foreign
income taxes.  This favorable adjustment resulted from USX's ability to elect to
credit, rather than deduct, foreign income taxes for U.S. federal income tax
purposes in future periods.  The anticipated use of the U.S. foreign tax credit
reflects Marathon's improving international production profile.  The income tax
provision for the third quarter of 1993 also included a $24 million charge
associated with an increase in the federal income tax rate from 34% to 35%.
This charge reflected a $29 million unfavorable remeasurement of deferred
federal income tax liabilities as of January 1, 1993, and a $5 million favorable
effect related to 1993 pretax losses.

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     The Board also declared a dividend of $0.8125 per share on USX
Corporation's 6.50% Cumulative Convertible Preferred Stock and $1.01875 per
share on USX Corporation's Adjustable Rate Cumulative Preferred Stock, in each
case payable December 30, 1994, to stockholders of record at the close of
business on December 1, 1994.

FINANCIAL CONDITION
- -------------------

Liquidity and Capital Resources
- --------------------------------
     At September 30, 1994, cash and cash equivalents totaled $87 million
compared with $268 million at December 31, 1993.

     Net cash provided from operating activities totaled $244 million in the
first nine months of 1994, compared with $645 million in the first nine months
of 1993.  The unfavorable change primarily reflected 1994 payments of $367
million to settle substantially all of the remaining judgments from the B&LE
litigation and 1994 payments of $124 million to settle various state tax issues.
In addition, net cash provided from operating activities in the first nine
months of 1993 benefited from a $103 million favorable effect from the use of
available funds from previously established insurance reserves to pay for
certain active and retired employee insurance benefits.  Excluding the 1994
payments and the 1993 favorable effect, net cash provided from operating
activities in the first nine months of 1994 increased $193 million from the same
period in 1993.

     Cash from the disposal of assets totaled $253 million in the first nine
months of 1994, compared with $269 million in the same period in 1993.  The 1994
proceeds mainly resulted from the sales of the assets of a retail propane
marketing subsidiary and certain domestic oil and gas production properties.
The 1993 proceeds primarily reflected the sale/leaseback of interests in two LNG
tankers and the sales of the Cumberland coal mine, various domestic oil and gas
production properties and an investment in an insurance company.

     USX's total long-term debt and notes payable at September 30, 1994, was
$5.7 billion, down $242 million from December 31, 1993.  In August 1994, USX
entered into a $2.325 billion revolving credit agreement which terminates in
August 1999.  Interest is based on defined short-term market rates.  This
agreement replaced the $2.0 billion in existing revolving credit agreements
entered into in October 1992.  At September 30, 1994, USX had no borrowings
against the long-term revolving credit agreement, but had outstanding borrowings
of $33 million against short-term lines of credit totaling $165 million, which
require maintenance of compensating balances of 3%.  At September 30, 1994, 
long-term debt included zero coupon convertible debentures which, at the option
of the holder, USX is obligated to purchase at the carrying value of 
$430 million on August 9, 1995.  USX may elect to pay the purchase price in
cash, shares of Marathon Stock and Steel Stock, notes or a combination thereof.

     In February 1994, USX issued $300 million in aggregate principal amount of
7.20% Notes Due 2004 and $150 million in aggregate principal amount of LIBOR-
based Floating Rate Notes Due 1996.  In March 1994, an aggregate principal
amount of

                  ---------------------------------------------

$57 million of Marathon's 7% Monthly Interest Guaranteed Notes Due 2002 was
issued in exchange for an equivalent principal amount of its 9-1/2% Guaranteed
Notes Due 1994 ("Marathon 9-1/2% Notes").  The $642 million balance of Marathon
9-1/2% Notes was paid in March 1994.  In June 1994, USX issued $55 million of
6.70% Environmental Improvement Revenue Refunding Bonds due 2020 and 2024 to 
refinance Environmental Improvement Bonds.

     In February 1994, USX sold 5,000,000 shares of Steel Stock to the public
for net proceeds of $201 million.

     In March 1994, USX Capital LLC, a wholly owned subsidiary of USX, sold $250
million of 8-3/4% Cumulative Monthly Income Preferred Shares.

     In March 1994, USX filed with the Securities and Exchange Commission
("SEC") a shelf registration statement which became effective April 8, 1994 and
allows USX to offer and issue unsecured debt securities in an aggregate
principal amount of up to $750 million in one or more separate series on terms
to be determined at the time of sale.  In August 1994, USX filed with the SEC a
shelf registration statement which became effective September 21, 1994 and
allows USX to offer and issue up to $137 million of debt and equity securities.
USX also has $345 million remaining on a shelf registration statement which
became effective January 6, 1994 and allows USX to offer and issue debt and
equity securities.

     USX engages in hedging activities in the normal course of its businesses.
Futures contracts, commodity swaps and options are used to hedge exposure to
price fluctuations relevant to the purchase or sale of crude oil, natural gas,
and refined products.  Forward contracts are used to hedge currency risks
related to firm commitments for capital expenditures and liabilities denominated
in a foreign currency.  While hedging activities are generally used to reduce
risks from unfavorable commodity price and currency rate movements, they also
may limit the opportunity to benefit from favorable movements.  USX's hedging
activities have not been significant in relation to its overall business
activity. Management believes that its use of hedging instruments will not have
a material effect on the financial position, liquidity or results of operations
of USX.

     USX believes that its short-term and long-term liquidity is adequate to
satisfy its obligations as of September 30, 1994, and to complete currently
authorized capital spending programs.  Future requirements for USX's business
needs, including the funding of capital expenditures, debt maturities for the
balance of 1994 and years 1995 and 1996 and amounts which may ultimately be paid
in connection with contingencies are expected to be financed by a combination of
internally generated funds, proceeds from the sale of stock, future borrowings
and other external financing sources.

Capital Expenditures
- --------------------
     Capital expenditures for property, plant, and equipment in the third
quarter and first nine months of 1994 were $258 million and $657 million,
respectively, compared with $279 million and $803 million in the same periods in
1993.  The declines in 1994 in both periods primarily reflected lower spending
for the Marathon Group mainly due to decreased expenditures resulting from the
substantial completion of the East Brae Field and SAGE system in the United
Kingdom and the distillate hydrotreater complex at the Robinson, Illinois
refinery.  For further details, see the Financial Statistics table.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     In addition to the capital expenditures discussed above, USX's noncash
activities in the first nine months of 1994 included the issuance of a $42
million purchase money note related to the acquisition of 36 gasoline
outlets/convenience stores from a petroleum retailer.

     For the year 1994, capital expenditures are expected to total approximately
$1.1 billion.  The decrease from 1993 of approximately $80 million is expected
to result mainly from lower spending for the Marathon Group, partially offset by
higher spending for the U. S. Steel Group.  For details, see discussion of
Capital Expenditures for the Marathon Group, the U. S. Steel Group and the Delhi
Group.

     Contract commitments for capital expenditures at September 30, 1994, were
$309 million, compared with $389 million at year-end 1993.

Environmental Matters, Contingencies and Commitments
- ----------------------------------------------------
     USX has incurred and will continue to incur substantial capital, operating
and maintenance, and remediation expenditures as a result of environmental laws
and regulations.  In recent years, these expenditures have increased primarily
due to required product reformulation and process changes in order to meet Clean
Air Act obligations, although ongoing compliance costs have also been
significant.  To the extent these expenditures, as with all costs, are not
ultimately reflected in the prices of USX's products and services, operating
results will be adversely affected.  USX believes that domestic competitors of
the U. S. Steel Group and substantially all the competitors of the Marathon
Group and the Delhi Group are subject to similar environmental laws and
regulations.  However, the specific impact on each competitor may vary depending
on a number of factors, including the age and location of their operating
facilities, their production processes and the specific products and services
they provide.

     USX has been notified that it is a potentially responsible party ("PRP") at
44 waste sites under the Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA") as of September 30, 1994.  In addition, there are 47
sites where USX has received information requests or other indications that USX
may be a PRP under CERCLA but where sufficient information is not presently
available to confirm the existence of liability or make any judgment as to the
amount thereof.  There are also 76 additional sites, excluding retail gasoline
stations, where remediation is being sought under other environmental statutes,
both federal and state, or where private parties are seeking remediation through
discussions or litigation.  At many of these sites, USX is one of a number of
parties involved and the total cost of remediation, as well as USX's share
thereof, is frequently dependent upon the outcome of investigations and remedial
studies.  The number of waste sites in and of itself does not necessarily
represent a relevant measure of liability because the nature and extent of
environmental concerns vary from site to site, and USX's share of responsibility
varies significantly.

     USX accrues for environmental remediation activities when the
responsibility to remediate is probable and the amount of associated costs is
reasonably determinable.  As environmental remediation matters proceed toward
ultimate resolution or as additional remediation obligations arise, charges in
excess of those previously accrued may be required.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     USX is the subject of, or a party to, a number of pending or threatened
legal actions, contingencies and commitments involving a variety of matters,
including laws and regulations relating to the environment (see Note 15 to the
consolidated financial statements for a discussion of certain of these matters).
The ultimate resolution of these contingencies could, individually or in the
aggregate, be material to the consolidated financial statements.  However,
management believes that USX will remain a viable and competitive enterprise
even though it is possible that these contingencies could be resolved
unfavorably.  See discussion of Liquidity and Capital Resources herein.

                        MARATHON GROUP OF USX CORPORATION
                     SELECTED NOTES TO FINANCIAL STATEMENTS
                     --------------------------------------
                                   (Unaudited)


 1.  The information furnished in these financial statements is unaudited but,
     in the opinion of management, reflects all adjustments necessary for a fair
     presentation of the results for the periods covered.  All such adjustments
     are of a normal recurring nature unless disclosed otherwise.  These
     financial statements, including selected notes, have been prepared in
     accordance with the applicable rules of the Securities and Exchange
     Commission and do not include all of the information and disclosures
     required by generally accepted accounting principles for complete financial
     statements.  Additional information is contained in the USX Annual Report
     on Form 10-K for the year ended December 31, 1993.  Financial data for the
     first nine months of 1993 has been restated to reflect the adoption of
     Statement of Financial Accounting Standards No. 112, "Employers' Accounting
     for Postemployment Benefits" (SFAS No. 112), and Emerging Issues Task Force
     Consensus No. 93-14, "Accounting for Multiple-Year Retrospectively Rated
     Insurance Contracts" (EITF No. 93-14) (see Note 8).

     The financial statements of the Marathon Group include the financial
     position, results of operations and cash flows for the businesses of
     Marathon Oil Company and certain other subsidiaries of USX, and a portion
     of the corporate assets and liabilities and related transactions which are
     not separately identified with ongoing operating units of USX.  These
     financial statements are prepared using the amounts included in the USX
     consolidated financial statements.  Corporate amounts reflected in these
     financial statements are determined based upon methods which management
     believes to be reasonable.  The accounting policies applicable to the
     preparation of the financial statements of the Marathon Group may be
     modified or rescinded in the sole discretion of the Board of Directors of
     USX (Board), although the Board has no present intention to do so.  The
     Board may also adopt additional policies depending on the circumstances.

     Although the financial statements of the Marathon Group, the U. S. Steel
     Group and the Delhi Group separately report the assets, liabilities
     (including contingent liabilities) and stockholders' equity of USX
     attributed to each such group, such attribution of assets, liabilities
     (including contingent liabilities) and stockholders' equity among the
     Marathon Group, U. S. Steel Group and the Delhi Group for the purpose of
     preparing their respective financial statements does not affect legal title
     to such assets and [or] responsibility for such liabilities.  Holders of
     USX-Marathon Group Common Stock (Marathon Stock), USX-U. S. Steel Group
     Common Stock (Steel Stock) and USX-Delhi Group Common Stock (Delhi Stock)
     are holders of common stock of USX, and continue to be subject to all the
     risks associated with an investment in USX and all of its businesses and
     liabilities.  Financial impacts arising from one Group that affect the
     overall cost of USX's capital could affect the results of operations and
     financial condition of other groups.  In addition, net losses of any Group,
     as well as dividends and distributions on any class of USX Common Stock or
     series of preferred stock and repurchases of any class of USX Common Stock
     or series of preferred stock at prices in excess of par or stated value,
     will reduce the funds of USX legally available for payment of dividends on
     all classes of Common Stock.  Accordingly, the USX consolidated financial
     information should be read in connection with the Marathon Group financial
     information.

                        MARATHON GROUP OF USX CORPORATION
               SELECTED NOTES TO FINANCIAL STATEMENTS (Continued)
               --------------------------------------------------
                                   (Unaudited)
                                        
                                        
 2.  The method of calculating net income per share for the Marathon Stock,
     Steel Stock and Delhi Stock reflects the Board's intent that the separately
     reported earnings and surplus of the Marathon Group, the U. S. Steel Group
     and the Delhi Group, as determined consistent with the USX Certificate of
     Incorporation, are available for payment of dividends to the respective
     classes of stock, although legally available funds and liquidation
     preferences of these classes of stock do not necessarily correspond with
     these amounts.

     Primary net income per share is calculated by adjusting net income for
     dividend requirements of preferred stock and is based on the weighted
     average number of common shares outstanding plus common stock equivalents,
     provided they are not antidilutive.  Common stock equivalents result from
     assumed exercise of stock options and surrender of stock appreciation
     rights associated with stock options, where applicable.

     Fully diluted net income per share assumes conversion of convertible
     securities for the applicable periods outstanding and assumes exercise of
     stock options and surrender of stock appreciation rights, provided, in each
     case, the effect is not antidilutive.

 3.  The items below were included in both sales and operating costs, resulting
     in no effect on income:

 4.  (Continued)

     The inventory market valuation reserve reflects the extent that the
     recorded costs of crude oil and refined products inventories exceed net
     realizable value.  The reserve is decreased to reflect increases in market
     prices and inventory turnover and increased to reflect decreases in market
     prices.  Changes in the inventory market valuation reserve resulted in a
     $158 million credit to operating income in the first nine months of 1994
     ($63 million charge in the third quarter) and a $54 million charge against
     operating income in the first nine months of 1993 ($30 million charge in
     the third quarter).

 5.  In the first nine months of 1994, payments of $123 million were made to
     settle various state tax issues.  As a result of these settlements, net
     income in the second quarter of 1994 included a net credit of $36 million,
     consisting of a credit of $12 million in operating costs, a credit of $34
     million in interest and other financial costs and a net income tax
     provision effect of $10 million.

 6.  Other income (loss) in the first nine months of 1994 included a pretax gain
     of $173 million from disposal of assets ($148 million in the third quarter,
     including the sale of the assets of a retail propane marketing subsidiary).

 7.  The financial statement provision for estimated income taxes and related
     tax payments or refunds have been reflected in the Marathon Group, the U.
     S. Steel Group and the Delhi Group financial statements in accordance with
     USX's tax allocation policy for such groups.  In general, such policy
     provides that the consolidated tax provision and related tax payments or
     refunds are allocated among the Marathon Group, the U. S. Steel Group and
     the Delhi Group for group financial statement purposes, based principally
     upon the financial income, taxable amount, credits, preferences and other
     amounts directly related to the respective groups.

     The provision for estimated income taxes for the Marathon Group is based on
     tax rates and amounts which recognize management's best estimate of current
     and deferred tax assets and liabilities.  Differences between the combined
     interim tax provisions of the Marathon, U. S. Steel and Delhi Groups and
     USX consolidated are allocated to each group based on the relationship of
     the individual group provisions to the combined interim provisions.

     The third quarter 1993 income tax provision included a credit of $64
    million related to recognition of future U.S. income tax benefits for
    deferred foreign income taxes.  This favorable adjustment resulted from
    USX's ability to elect to credit, rather than deduct, foreign income taxes
    for U.S. federal income tax purposes in future periods.  The third quarter
    1993 income tax provision also included a $40 million charge associated
    with an increase in the federal income tax rate from 34% to 35%, reflecting
    remeasurement of  deferred federal income tax liabilities as of January 1,
    1993.

 8.  In 1993, USX adopted SFAS No. 112 and EITF No. 93-14. The cumulative effect
     of these changes in accounting principles decreased first quarter 1993 net
     income by $17 million, net of $10 million income tax effect, for SFAS No.
     112; and $6 million, net of $3 million income tax effect, for EITF No. 93-
     14.

 9.  In the first quarter of 1994, USX Capital LLC, a wholly owned subsidiary of
     USX, sold $250 million of 8-3/4% Cumulative Monthly Income Preferred Shares
     (MIPS).  In accordance with the USX policy of managing most financial
     activities on a centralized, consolidated basis, the proceeds from issuance
     of the MIPS and the related financial costs (which are included in interest
     and other financial costs) were attributed to all three groups in
     proportion to their respective participation in USX centrally managed
     financing activities.

10.  The Marathon Group has entered into an agreement, subject to limited
     recourse, to sell certain accounts receivable including accounts receivable
     purchased from the Delhi Group.  Payments are collected from the sold
     accounts receivable; the collections are reinvested in new accounts
     receivable for the buyers; and a yield based on defined short-term market
     rates is transferred to the buyers.  At September 30, 1994, the balance of
     sold accounts receivable that had not been collected was $400 million.
     Buyers have collection rights to recover payments from an amount of
     outstanding receivables equal to 120% of the outstanding receivables
     purchased on a nonrecourse basis; such overcollateralization cannot exceed
     $80 million.  In the event of a change in control of USX, as defined in the
     agreement, the Marathon Group may be required to forward payments collected
     on sold accounts receivable to the buyers.

11.  USX is the subject of, or a party to, a number of pending or threatened
     legal actions, contingencies and commitments relating to the Marathon Group
     involving a variety of matters, including laws and regulations relating to
     the environment.  Certain of these matters are discussed below.  The
     ultimate resolution of these contingencies could, individually or in the
     aggregate, be material to the Marathon Group financial statements.
     However, management believes that USX will remain a viable and competitive
     enterprise even though it is possible that these contingencies could be
     resolved unfavorably to the Marathon Group.  See discussion of Liquidity
     and Capital Resources in USX Consolidated Management's Discussion and
     Analysis of Financial Condition and Results of Operations.

     The Marathon Group is subject to federal, state, local and foreign laws and
     regulations relating to the environment.  These laws generally provide for
     control of pollutants released into the environment and require responsible
     parties to undertake remediation of hazardous waste disposal sites.
     Penalties may be imposed for noncompliance.  The Marathon Group provides
     for remediation costs and penalties when the responsibility to remediate is
     probable and the amount of associated costs is reasonably determinable.
     Generally, the timing of these accruals coincides with completion of a
     feasibility study or the commitment to a formal plan of action.  Estimated
     abandonment and dismantlement costs of offshore production platforms are
     accrued based upon estimated proved oil and gas reserves on a units-of-
     production method.  At September 30, 1994, accrued liabilities for
     remediation and platform abandonment totaled $169 million.  It is not
     presently possible to estimate the ultimate amount of all remediation costs
     that might be incurred or the penalties that may be imposed.

11.  (Continued)

     For a number of years, the Marathon Group has made substantial capital
     expenditures to bring existing facilities into compliance with various laws
     relating to the environment.  In 1993 and 1992, such capital expenditures
     totaled $123 million and $240 million, respectively.  The Marathon Group
     anticipates making additional such expenditures in the future; however, the
     exact amounts and timing of such expenditures are uncertain because of the
     continuing evolution of specific regulatory requirements.

     By reason of Executive Orders and related regulations under which the U.S.
     Government is continuing economic sanctions against Libya, the Marathon
     Group was required to discontinue performing its Libyan petroleum contracts
     on June 30, 1986.  In June 1989, the Department of the Treasury authorized
     the Marathon Group to resume performing under those contracts.  Pursuant to
     that authorization, the Marathon Group has engaged the Libyan National Oil
     Company and the Secretary of Petroleum in continuing negotiations to
     determine when and on what basis they are willing to allow the Marathon
     Group to resume realizing revenue from the Marathon Group's investment of
     $108 million in Libya.  The Marathon Group is uncertain when these
     negotiations can be completed or how the negotiations will be affected by
     the United Nations' sanctions against Libya.

     Guarantees by USX of the liabilities of affiliated and other entities of
     the Marathon Group totaled $18 million at September 30, 1994.

     At September 30, 1994, the Marathon Group's pro rata share of obligations
     of LOOP INC. and various pipeline affiliates secured by throughput and
     deficiency agreements totaled $196 million.  Under the agreements, the
     Marathon Group is required to advance funds if the affiliates are unable to
     service debt.  Any such advances are prepayments of future transportation
     charges.

     At September 30, 1994, contract commitments for the Marathon Group's
     capital expenditures for property, plant and equipment totaled $215 million
     compared with $284 million at December 31, 1993.

                        MARATHON GROUP OF USX CORPORATION
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     The Marathon Group includes Marathon Oil Company (Marathon) and certain
other subsidiaries of USX which are engaged in worldwide exploration,
production, transportation and marketing of crude oil and natural gas; and
domestic refining, marketing and transportation of petroleum products.  The
following discussion should be read in conjunction with the third quarter 1994
USX consolidated financial information and the Marathon Group financial
statements and selected notes.

Results of Operations
- ---------------------
     The Marathon Group reported net income of $102 million, or $.35 per share,
in the third quarter of 1994, compared to net income of $30 million, or $.10 per
share, in the same quarter of 1993.  The Marathon Group had net income of $284
million, or $.98 per share, in the first nine months of 1994.  Net income in the
first nine months of 1993 was $59 million, or $.19 per share, as restated to
reflect the unfavorable $23 million ($.08 per share) cumulative effect of
changes in accounting principles.

     Sales in the third quarter of 1994 were $3,497 million, compared with
$2,983 million in the third quarter of 1993.  The 17% improvement primarily
reflected increased excise taxes, which totaled $733 million in the third
quarter of 1994 compared with $511 million in the third quarter of 1993; as well
as higher worldwide liquid hydrocarbon volumes and higher refined product
prices.  Sales in the first nine months of 1994 were $9,349 million, compared
with $9,040 million in the first nine months of 1993.  The improvement primarily
reflected increased excise taxes, which totaled $1,878 million in the first nine
months of 1994 compared with $1,407 million in the first nine months of 1993; as
well as higher worldwide liquid hydrocarbon volumes, partially offset by lower
worldwide liquid hydrocarbon prices, including prices of matching buy/sell
transactions.  Matching buy/sell transactions and excise taxes are included in
both sales and operating costs, resulting in no effect on operating income.
Higher excise taxes were the predominant factor in the increase in taxes other
than income taxes in both periods in 1994.

     Operating income was $117 million in the third quarter of 1994, compared
with operating income of $84 million in the third quarter of 1993.  Third
quarter operating income for 1994 and 1993 included unfavorable noncash effects
of $63 million and $30 million, respectively, resulting from increases in the
inventory market valuation reserve.  The inventory market valuation reserve
reflects the extent to which the recorded costs of crude oil and refined product
inventories exceed net realizable value.  Subsequent changes to the inventory
market valuation reserve are dependent on changes in future crude oil and
refined product price levels and inventory turnover.  The following discussion
of third quarter results excludes the effects of changes in the inventory market
valuation reserve.

     Operating income in the third quarter of 1994 increased $66 million from
the third quarter of 1993.  The 58% increase was primarily due to increased
operating income from worldwide exploration and production, partially offset by
reduced operating income from refining, marketing and transportation operations.

     Operating income from worldwide exploration and production was $73 million
in the third quarter of 1994, compared with a loss of $9 million in the third
quarter

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

of 1993.  Domestic exploration and production operating income was $53 million
in the third quarter of 1994, compared with $10 million in the third quarter of
1993.  The significant increase in domestic exploration and production operating
income was primarily due to reduced operating expenses, higher liquid
hydrocarbon prices, higher natural gas volumes and prices, and reduced dry well
expense.

     International exploration and production operating income was $20 million
in the third quarter of 1994, compared with a loss of $19 million in the third
quarter of 1993.  The $39 million increase was primarily due to increased liquid
hydrocarbon liftings and the absence of a 1993 charge of $17 million for
relinquishment of the Marathon Group's interest in the Arzanah Oil Field, Abu
Dhabi.  The increase in liftings mainly reflected production from the East Brae
Field in the United Kingdom ("U.K.") which began in late December 1993.
Marathon's contractual Brae area gas sales commenced on October 1 and are 
expected to average approximately 130 million cubic feet per day during the
coming year.

     Operating income from refining, marketing and transportation operations was
$123 million in the third quarter of 1994, compared with $146 million in the
third quarter of 1993.   The 16% decrease was primarily due to lower margins
from refined products and convenience store merchandise, as well as increased
operating expenses, partially offset by a favorable effect relating to a legal
settlement.  In the fourth quarter of 1994, the Marathon Group completed the
acquisition of 53 gasoline outlets/convenience stores in Tennessee and Michigan
from petroleum retailers.

     In the first nine months of 1994, operating income was $499 million,
compared to operating income of $284 million in the first nine months of 1993.
The first nine months included a $158 million favorable noncash effect in 1994
and a $54 million unfavorable noncash effect in 1993 resulting from changes in
the inventory market valuation reserve.  Excluding the effects of these changes
in the inventory market valuation reserve, operating income in the first nine
months of 1994 increased $3 million from the first nine months of 1993.  The
slight increase was mainly due to reduced worldwide production operating
expenses, partially offset by lower worldwide liquid hydrocarbon prices.  In
addition, the first nine months of 1994 included $36 million for employee
reorganization charges.  The reorganization charges included $22 million for
worldwide exploration and production; $13 million for refining, marketing and
transportation; and $1 million for administrative.  These charges relate to
employee severance and relocation costs associated with work force reduction
programs.  Employee reorganization charges in the fourth quarter are not
expected to be material.  Annual pretax reductions in employment costs and
associated overhead costs of approximately $80 million are expected to be
realized after full implementation of the work force reduction programs in place
during 1994.

     Other income of $166 million was recorded in the first nine months of 1994,
compared with other income of $21 million in the first nine months of 1993.  The
increase in 1994 was primarily due to the third quarter sale of the assets of a
retail propane marketing subsidiary and the first quarter sale of certain
domestic oil and gas production properties.

     Net interest and other financial costs in the first nine months of 1994
included a $34 million favorable effect resulting from settlement of various
state tax issues.

                        MARATHON GROUP OF USX CORPORATION

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------
                                        
     The provision for estimated income taxes for the periods reported is based
on tax rates and amounts which recognize management's best estimate of current
and deferred tax assets and liabilities.  The third quarter 1993 income tax
provision included a credit of $64 million related to recognition of additional
future U.S. income tax benefits for deferred foreign income taxes.  This
favorable adjustment resulted from USX's ability to elect to credit, rather than
deduct, foreign income taxes for U.S. federal income tax purposes in future
periods.  The anticipated use of the U.S. foreign tax credit reflects Marathon's
improving international production profile.  The income tax provision for the
third quarter of 1993 also included a $40 million charge associated with an
increase in the federal income tax rate from 34% to 35% reflecting remeasurement
of deferred federal income tax liabilities as of January 1, 1993.

     The Marathon Group's posted price for West Texas Intermediate, a benchmark
crude oil, averaged $16.15 per barrel in October 1994, compared to a third
quarter average of $16.98 per barrel.  The outlook regarding prices and costs
for the Marathon Group's principal products is largely dependent upon world
market developments for crude oil and refined products.  Market conditions in
the petroleum industry are cyclical and subject to global economics and
political events.

     The Marathon Group closed its Lubricants and Tires, Batteries and
Accessories supply facility in Robinson, Illinois on October 31, 1994.  Marathon
brand and company-operated retail outlets are being supplied by third-party
vendors.  The costs related to the closure are not expected to have a material
effect on the Marathon Group's operating results.

     Employees at the Detroit refinery are represented by the International
Brotherhood of Teamsters ("Teamsters") under a labor agreement which expires on
November 15, 1994.  During October, management and the Teamsters began
discussions regarding a new labor agreement.

     The Marathon Group and Union Oil Company of California (Unocal) entered
into an agreement, intended to become effective December 1, 1994, to complete a
major property trade and realignment of operations in the Cook Inlet Region of
Alaska.  The Marathon Group is to acquire Unocal's working interest in the
Cannery Loop, Beaver Creek and Kenai fields.  In exchange, Unocal is to acquire
the Marathon Group's working interest in the Swanson River Field and operator
interest in the Trading Bay Unit, which includes two platforms and an onshore
processing facility.

     Effective December 1, 1994, the Marathon Group will be required to sell
reformulated gasoline at wholesale distribution terminals serving ozone
nonattainment areas that require reformulated gasoline.  Beginning January 1,
1995, the Marathon Group's retail outlets located in those areas will be
required to sell reformulated gasoline.  The areas in the Marathon Group's
marketing territory requiring reformulated gasoline are limited to the Chicago,
Illinois; Milwaukee, Wisconsin and Louisville, Kentucky metropolitan areas.  The
Marathon Group is well positioned to supply the reformulated gasoline in its
marketing area, and it has already begun the production of reformulated
gasoline.  In addition, the Marathon Group will make reformulated gasoline to be
sold for use in the East Coast market.

Cash Flows
- ----------
     Net cash provided from operating activities was $285 million in the first
nine months of 1994, compared with $457 million in the first nine months of
1993.  The first nine months of 1994 included second quarter payments of $123
million related to settlement of various state tax issues.  Excluding these
payments, net cash flows from operating activities in the first nine months of
1994 decreased $49 million from the first nine months of 1993.

     Cash provided from the disposal of assets was $233 million in the first
nine months of 1994, compared with $112 million in the first nine months of
1993.  Proceeds in the first nine months of 1994 mainly reflected the sales of
the assets of a retail propane marketing subsidiary and certain domestic oil and
gas production properties.  Proceeds in the first nine months of 1993 primarily
reflected the sale/leaseback of interests in two LNG tankers and the sales of
various domestic oil and gas production properties.

     Financial obligations decreased $40 million in the first nine months of
1994, reflecting net cash provided from operating activities and a reduction in
attributed cash and cash equivalents, partially offset by net cash flows used in
investing activities and dividends paid during the period.  Financial
obligations consist of the Marathon Group's portion of USX debt and preferred
stock of a subsidiary attributed to all three groups.

     The Marathon Group engages in hedging activities in the normal course of
its business.  Futures contracts, commodity swaps and options are used to hedge
exposure to price fluctuations relevant to the purchase or sale of crude oil,
natural gas and refined products.  Forward contracts are used to hedge currency
risks related to firm commitments for capital expenditures and liabilities
denominated in a foreign currency.  While hedging activities are generally used
to reduce risks from unfavorable commodity price and currency rate movements,
they also may limit the opportunity to benefit from favorable movements.  The
Marathon Group's hedging activities have not been significant in relation to its
overall business activity.  Management believes that its use of hedging
instruments will not have a material effect on the financial position, liquidity
or results of operations of the Marathon Group.

     For discussion of USX's liquidity and capital resources, see USX
Consolidated Management's Discussion and Analysis of Financial Condition and
Results of Operations.

Capital Expenditures
- --------------------
     Marathon Group capital expenditures for property, plant and equipment in
the third quarter and first nine months of 1994 were $187 million and $464
million, respectively, compared with $215 million and $646 million in the same
periods in 1993.  The declines in both periods were primarily due to decreased
expenditures resulting from the substantial completion of the East Brae Field
and SAGE system in the United Kingdom and the distillate hydrotreater complex at
the Robinson, Illinois refinery.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     In addition to the capital expenditures discussed above, the Marathon
Group's noncash activities in the first nine months of 1994 included the
issuance of a $42 million purchase money note related to the acquisition of 36
gasoline outlets/convenience stores from a petroleum retailer.

     For the year 1994, capital expenditures are expected to decrease from $910
million in 1993 by approximately $130 million.  The decline mainly reflects
decreased expenditures for development of the East Brae Field and SAGE system in
the United Kingdom.

     Contract commitments for capital expenditures at September 30, 1994 were
$215 million, compared with $284 million at year-end 1993.

Environmental Matters, Contingencies and Commitments
- ----------------------------------------------------
     The Marathon Group has incurred and will continue to incur substantial
capital, operating and maintenance, and remediation expenditures as a result of
environmental laws and regulations.  In recent years, these expenditures have
increased primarily due to required product reformulation and process changes in
order to meet Clean Air Act obligations, although ongoing compliance costs have
also been significant.  To the extent these expenditures, as with all costs, are
not ultimately reflected in the prices of the Marathon Group's products and
services, operating results will be adversely affected.  The Marathon Group
believes that substantially all of its competitors are subject to similar
environmental laws and regulations.  However, the specific impact on each
competitor may vary depending on a number of factors, including the age and
location of their operating facilities, their production processes and whether
or not they are engaged in the petrochemical business or the marine
transportation of crude oil.

     USX has been notified that it is a potentially responsible party ("PRP") at
nine waste sites related to the Marathon Group under the Comprehensive
Environmental Response, Compensation and Liability Act ("CERCLA") as of
September 30, 1994.  In addition, there are 22 sites related to the Marathon
Group where USX has received information requests or other indications that USX
may be a PRP under CERCLA but where sufficient information is not presently
available to confirm the existence of liability or make any judgment as to the
amount thereof.  There are also 40 additional sites, excluding retail gasoline
stations, related to the Marathon Group where remediation is being sought under
other environmental statutes, both federal and state, or where private parties
are seeking remediation through discussions or litigation.  At many of these
sites, USX is one of a number of parties involved and the total cost of
remediation, as well as USX's share thereof, is frequently dependent upon the
outcome of investigations and remedial studies.  The number of waste sites in
and of itself does not necessarily represent a relevant measure of liability
because the nature and extent of environmental concerns vary from site to site,
and USX's share of responsibility varies significantly.

     The Marathon Group accrues for environmental remediation activities when
the responsibility to remediate is probable and the amount of associated costs
is reasonably determinable.  As environmental remediation matters proceed toward
ultimate resolution or as additional remediation obligations arise, charges in
excess of those previously accrued may be required.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     USX is the subject of, or a party to, a number of pending or threatened
legal actions, contingencies and commitments relating to the Marathon Group
involving a variety of matters, including laws and regulations relating to the
environment (see Note 11 to the Marathon Group financial statements for a
discussion of certain of these matters).  The ultimate resolution of these
contingencies could, individually or in the aggregate, be material to the
Marathon Group financial statements.  However, management believes that USX will
remain a viable and competitive enterprise even though it is possible that these
contingencies could be resolved unfavorably to the Marathon Group.  See
discussion of Liquidity and Capital Resources in USX Consolidated Management's
Discussion and Analysis of Financial Condition and Results of Operations.

                      U. S. STEEL GROUP OF USX CORPORATION
                     SELECTED NOTES TO FINANCIAL STATEMENTS
                     --------------------------------------
                                   (Unaudited)
                                        
                                        
 1.  The information furnished in these financial statements is unaudited but,
     in the opinion of management, reflects all adjustments necessary for a fair
     presentation of the results for the periods covered.  All such adjustments
     are of a normal recurring nature unless disclosed otherwise.  These
     financial statements, including selected notes, have been prepared in
     accordance with the applicable rules of the Securities and Exchange
     Commission and do not include all of the information and disclosures
     required by generally accepted accounting principles for complete financial
     statements.  Additional information is contained in the USX Annual Report
     on Form 10-K for the year ended December 31, 1993.  Financial data for the
     first nine months of 1993 has been restated to reflect the adoption of
     Statement of Financial Accounting Standards No. 112, "Employers' Accounting
     for Postemployment Benefits" (SFAS No. 112) (see Note 8).

     The financial statements of the U. S. Steel Group include the financial
     position, results of operations and cash flows for all businesses of USX
     other than the businesses, assets and liabilities included in the Marathon
     Group or the Delhi Group, and a portion of the corporate assets and
     liabilities and related transactions which are not separately identified
     with ongoing operating units of USX.  These financial statements are
     prepared using the amounts included in the USX consolidated financial
     statements.  Corporate amounts reflected in these financial statements are
     determined based upon methods which management believes to be reasonable.
     The accounting policies applicable to the preparation of the financial
     statements of the U.S. Steel Group may be modified or rescinded in the sole
     discretion of the Board of Directors of USX (Board), although the Board has
     no present intention to do so.  The Board may also adopt additional
     policies depending on the circumstances.

     Although the financial statements of the U. S. Steel Group, the Marathon
     Group and the Delhi Group separately report the assets, liabilities
     (including contingent liabilities) and stockholders' equity of USX
     attributed to each such group, such attribution of assets, liabilities
     (including contingent liabilities) and stockholders' equity among the U. S.
     Steel Group, the Marathon Group and the Delhi Group for the purpose of
     preparing their respective financial statements does not affect legal title
     to such assets and responsibility for such liabilities.  Holders of USX-
     U. S. Steel Group Common Stock (Steel Stock), USX-Marathon Group Common
     Stock (Marathon Stock) and USX-Delhi Group Common Stock (Delhi Stock) are
     holders of common stock of USX, and continue to be subject to all the risks
     associated with an investment in USX and all of its businesses and
     liabilities.  Financial impacts arising from one Group that affect the
     overall cost of USX's capital could affect the results of operations and
     financial condition of other groups.  In addition, net losses of any Group,
     as well as dividends and distributions on any class of USX Common Stock or
     series of preferred stock and repurchases of any class of USX Common Stock
     or series of preferred stock at prices in excess of par or stated value,
     will reduce the funds of USX legally available for payment of dividends on
     all classes of Common Stock.  Accordingly, the USX consolidated financial
     information should be read in connection with the U. S. Steel Group
     financial information.

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

 2.  The method of calculating net income (loss) per share for the Steel Stock,
     Marathon Stock and Delhi Stock reflects the Board's intent that the
     separately reported earnings and surplus of the U. S. Steel Group, the
     Marathon Group and the Delhi Group, as determined consistent with the USX
     Certificate of Incorporation, are available for payment of dividends to the
     respective classes of stock, although legally available funds and
     liquidation preferences of these classes of stock do not necessarily
     correspond with these amounts.

     Primary net income (loss) per share is calculated by adjusting net income
     (loss) for dividend requirements of preferred stock and is based on the
     weighted average number of common shares outstanding plus common stock
     equivalents, provided they are not antidilutive.  Common stock equivalents
     result from assumed exercise of stock options and surrender of stock
     appreciation rights associated with stock options, where applicable.

     Fully diluted net income (loss) per share assumes conversion of convertible
     securities for the applicable periods outstanding and assumes exercise of
     stock options and surrender of stock appreciation rights provided, in each
     case, the effect is not antidilutive.

 3.  Inventories are carried at the lower of cost or market.  Cost of
     inventories is determined primarily under the last-in, first-out (LIFO)
     method.

     Cost of sales was reduced by $12 million in the first nine months of 1993
     ($2 million decrease in the third quarter of 1993) as a result of
     liquidations of LIFO inventories (immaterial in the 1994 periods).

 4.  Pretax income (loss) in the first nine months of 1993 included a $633
     million charge for the Lower Lake Erie Iron Ore Antitrust Litigation
     against a former USX subsidiary, the Bessemer & Lake Erie Railroad (B&LE).
     Charges of $438 million were included in operating costs and $195 million
     ($14 million in the third quarter) included in interest and other financial
     costs.  The effect on net income (loss) was $406 million unfavorable ($6.50
     per share).

 5.  Operating income (loss) included net periodic pension credits of $93
     million and $155 million in the first nine months of 1994 and 1993,
     respectively, ($32 million and $52 million in the third quarter of 1994 and
     1993, respectively).  These pension credits are primarily noncash and for
     the most part are included in selling, general and administrative expenses.

 5.  (Continued)

     expected long-term rate of return on plan assets, which is reflected in the
     calculation of net periodic pension credits, was reduced to 9% in 1994 from
     10% in 1993.

 6.  Other income in the first nine months of 1993 included a pretax gain of
     $139 million from disposal of assets, primarily related to the second
     quarter sale of the Cumberland coal mine.

 7.  The financial statement provision for estimated income taxes and related
     tax payments or refunds have been reflected in the U. S. Steel Group, the
     Marathon Group and the Delhi Group financial statements in accordance with
     USX's tax allocation policy for such groups.  In general, such policy
     provides that the consolidated tax provision and related tax payments or
     refunds are allocated among the U. S. Steel Group, the Marathon Group and
     the Delhi Group for group financial statement purposes, based principally
     upon the financial income, taxable amount, credits, preferences and other
     amounts directly related to the respective groups.

     The credit for estimated income taxes for the U. S. Steel Group is based on
     tax rates and amounts which recognize management's best estimate of current
     and deferred tax assets and liabilities.  Differences between the combined
     interim tax provisions of the U. S. Steel, Marathon and Delhi Groups and
     USX consolidated are allocated to each group based on the relationship of
     the individual group provisions to the combined interim provisions.

     The provision for the third quarter and first nine months of 1994 included
     a one-time $32 million deferred tax benefit related to the excess of tax
     over financial basis in shares of RMI Titanium Company (RMI), concurrent
     with the adoption of equity accounting for RMI.  The third quarter 1993
     income tax provision included a $20 million favorable effect associated
     with an increase in the federal income tax rate from 34% to 35%.  This
     credit reflected a $15 million remeasurement of deferred federal income tax
     assets as of January 1, 1993, and a $5 million tax credit related to 1993
     pretax losses.

 8.  In 1993, USX adopted SFAS No. 112. The cumulative effect of this change in
     accounting principle decreased first quarter 1993 net income of the U. S.
     Steel Group by $69 million, net of $40 million income tax effect.

 9.  In the first quarter of 1994, USX sold 5,000,000 shares of USX-U. S. Steel
     Group Common Stock to the public for net proceeds of $201 million, which
     have been reflected in their entirety in the financial statements of the U.
     S. Steel Group.

     In the first quarter of 1994, USX Capital LLC, a wholly owned subsidiary of
     USX, sold $250 million of 8-3/4% Cumulative Monthly Income Preferred Shares
     (MIPS).  In accordance with the USX policy of managing most financial
     activities on a centralized, consolidated basis, the proceeds from issuance
     of the MIPS and the related financial costs (which are included in interest
     and other financial costs) were attributed to all three groups in
     proportion to their respective participation in USX centrally managed
     financing activities.

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


11.  The U. S. Steel Group has entered into an agreement to sell certain
    accounts receivable subject to limited recourse.  Payments are collected
    from the sold accounts receivable; the collections are reinvested in new
    accounts receivable for the buyers; and a yield based on defined short-term
    market rates is transferred to the buyers.  At September 30, 1994, the
    balance of sold accounts receivable that had not been collected was $350
    million.  Buyers have collection rights to recover payments from an amount
    of outstanding receivables equal to 120% of the outstanding receivables
    purchased on a nonrecourse basis; such overcollateralization cannot exceed
    $70 million.  In the event of a change in control of USX, as defined in the
    agreement, the U. S. Steel Group may be required to forward payments
    collected on sold accounts receivable to the buyers.

     Prior to 1993, USX Credit, a division of USX, sold certain of its loans
    receivable subject to limited recourse.  USX Credit continues to collect
    payments from the loans and transfer to the buyers principal collected plus
    yield based on defined short-term market rates.  At September 30, 1994, the
    balance of sold loans receivable subject to recourse was $150 million.  As
    of September 30, 1994, USX Credit had outstanding loan commitments of
    $29 million.  USX Credit is not actively making new loan commitments.  In
    the event of a change in control of USX, as defined in the agreement, the
    U. S. Steel Group may be required to provide cash collateral in the amount
    of the uncollected loans receivable to assure compliance with the limited
    recourse provisions.

12.  USX is the subject of, or a party to, a number of pending or threatened
    legal actions, contingencies and commitments involving a variety of matters
    including laws and regulations relating to the environment.  Certain of
    these matters are discussed below.  The ultimate resolution of these
    contingencies could, individually or in the aggregate, be material to the
    U. S. Steel Group financial statements.  However, management believes that
    USX will remain a viable and competitive enterprise even though it is
    possible that these contingencies could be resolved unfavorably to the U.
    S. Steel Group.  See discussion of Liquidity and Capital Resources in USX
    Consolidated Management's Discussion and Analysis of Financial Condition
    and Results of Operations.

     In the first nine months of 1994, USX paid $367 million to settle
    substantially all of the remaining judgments against the B&LE in the Lower
    Lake Erie Iron Ore Antitrust Litigation.  Two remaining plaintiffs in this
    case have had their damage claims remanded for retrial.  A new trial may
    result in awards more or less than the original asserted claims of $8
    million and would be subject to trebling.

     On November 3, 1992, the United States District Court for the District of
     Utah Central Division issued a Memorandum Opinion and Order in Pickering v.
     USX relating to pension and compensation claims by approximately 1,900
     employees of USX's former Geneva (Utah) Works.  Although the court
     dismissed a number of the claims by the plaintiffs, it found that USX had
     violated the Employee Retirement Income Security Act by interfering with
     the accrual of pension benefits of certain employees and amending a benefit
     plan to reduce the accrual of future benefits without proper notice to plan
     participants.  Further proceedings were held to determine damages and,
     pending the court's determinations, USX may appeal.  Plaintiffs' counsel
     has been reported as estimating plaintiffs' anticipated recovery to be in
     excess of $100 million.

     USX believes actual damages will be substantially less than plaintiffs'
    estimates.  In the first quarter of 1994, USX entered into settlement
    agreements with 208 plaintiffs providing for releases of liability against
    USX and the aggregate payment of approximately $1 million by USX.  An order
    dismissing these plaintiffs from the case with prejudice was entered on
    May 31, 1994.

     The U. S. Steel Group is subject to federal, state, local and foreign laws
    and regulations relating to the environment.  These laws generally provide
    for control of pollutants released into the environment and require
    responsible parties to undertake remediation of hazardous waste disposal
    sites.  Penalties may be imposed for noncompliance.  The U. S. Steel Group
    provides for remediation costs and penalties when the responsibility to
    remediate is probable and the amount of associated costs is reasonably
    determinable.  Generally, the timing of these accruals coincide with
    completion of a feasibility study or the commitment to a formal plan of
    action.  Estimated mine reclamation costs are accrued based on actual clean
    tons of coal produced.  At September 30, 1994, accrued liabilities for
    remediation and mine reclamation totaled $150 million.  It is not presently
    possible to estimate the ultimate amount of all remediation costs that
    might be incurred or the penalties that may be imposed.

     For a number of years, the U. S. Steel Group has made substantial capital
    expenditures to bring existing facilities into compliance with various laws
    relating to the environment.  In 1993 and 1992, such capital expenditures
    totaled $53 million and $52 million, respectively.  The U. S. Steel Group
    anticipates making additional such expenditures in the future; however, the
    exact amounts and timing of such expenditures are uncertain because of the
    continuing evolution of specific regulatory requirements.

     Guarantees by USX of the liabilities of affiliated entities of the U. S.
    Steel Group totaled $185 million at September 30, 1994.  In the event that
    any defaults of guaranteed liabilities occur, USX has access to its
    interest in the assets of the affiliates to reduce U. S. Steel Group losses
    resulting from these guarantees.  As of September 30, 1994, the largest
    guarantee for a single affiliate was $94 million.

     At September 30, 1994, contract commitments for the U. S. Steel Group's
    capital expenditures for property, plant and equipment totaled $94 million
    compared with $105 million at December 31, 1993.

                      U. S. STEEL GROUP OF USX CORPORATION
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     The U. S. Steel Group includes U. S. Steel, which is primarily engaged in
the production and sale of a wide range of steel mill products, coke and
taconite pellets.  The U. S. Steel Group also includes the management of mineral
resources, domestic coal mining, engineering and consulting services and
technology licensing (together with U. S. Steel, the "Steel and Related
Businesses").  Other businesses that are part of the U. S. Steel Group include
real estate development and management, fencing products, and leasing and
financing activities.  The following discussion should be read in conjunction
with the third quarter 1994 USX consolidated financial information and the U. S.
Steel Group financial statements and selected notes.

Results of Operations
- ---------------------
     The U. S. Steel Group had net income of $90 million, or $1.11 per share, in
the third quarter of 1994, compared with restated net income of $33 million, or
$.41 per share, in the same quarter of 1993.  The U. S. Steel Group had net
income of $111 million, or $1.23 per share, in the first nine months of 1994.
The net loss in the first nine months of 1993 was $362 million, or $6.05 per
share, as restated to reflect the unfavorable $69 million ($1.11 per share)
cumulative effect of a change in accounting principle.

     Third quarter 1994 sales totaled $1.5 billion, compared with $1.4 billion
in the same quarter last year.  The $76 million increase mainly reflected higher
steel prices and shipment volumes, revenue related to the sale of coal seam
methane gas royalty interests and increased commercial shipments of coke,
partially offset by lower project revenues from engineering and consulting
services and lower revenues following the adoption of equity accounting for RMI
Titanium Company during the third quarter of 1994.  Sales in the first nine
months of 1994 totaled $4.4 billion, compared with $4.1 billion in the first
nine months of 1993.  The $359 million improvement mainly resulted from higher
steel shipment volumes and prices and increased commercial shipments of coke,
partially offset by lower commercial shipments of coal.

     The U. S. Steel Group reported operating income of $106 million in the
third quarter of 1994, compared with restated operating income of $66 million in
the same quarter of 1993.  The $40 million improvement was primarily due to
improved results from Steel and Related Businesses.

     Steel and Related Businesses reported operating income of $83 million in
the third quarter of 1994, compared with operating income of $45 million in the
same quarter last year.  The increase was predominantly due to higher average
prices for steel products, as well as income of $13 million related to the sale
of coal seam methane gas royalty interests, improved results from coal
operations and higher steel shipment volumes.  These favorable items were
partially offset by higher pension and labor costs and unfavorable effects
resulting from planned blast furnace outages at Gary (IN) Works and Fairfield
(AL) Works.

     Other Businesses had an operating loss of $5 million in the third quarter
of 1994, compared with an operating loss of $8 million in the same quarter of
1993.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     Operating income from Administrative, which includes pension credits, other
postretirement benefit costs and certain other expenses principally attributable
to former business units of the U. S. Steel Group, as well as the portion of USX
corporate general and administrative costs allocated to the U. S. Steel Group,
totaled $28 million in the third quarter of 1994, compared with $29 million in
the third quarter of 1993.

     The U. S. Steel Group reported operating income of $170 million in the
first nine months of 1994, compared with a restated operating loss of $286
million in the same period of 1993.  The operating loss in the first nine months
of 1993 included a $438 million charge for the Lower Lake Erie Iron Ore
Antitrust Litigation against the Bessemer & Lake Erie Railroad ("B&LE"), a
former USX subsidiary, and benefited from a $39 million favorable effect from
the utilization of funds from previously established insurance reserves to pay
for certain employee insurance benefits.  Excluding these items, operating
income in the first nine months of 1994 improved by $57 million from the first
nine months of 1993.  The increase primarily reflected higher steel prices and
shipment volumes, partially offset by higher pension, labor and scrap metal
costs and the adverse effects of outages at Mon Valley (PA) Works and Gary
Works.

     Other income in the first nine months of 1993 included a pretax gain of
$139 million from the disposal of assets, including the sales of the Cumberland
coal mine and an investment in an insurance company.  Income from affiliated
operations in the third quarter and first nine months of 1994 improved by $11
million and $41 million, respectively, from the same periods in 1993.

     Net interest and other financial costs in the third quarter and first nine
months of 1993 included $14 million and $195 million, respectively, of interest
expense related to the B&LE litigation.

     The provision (credit) for estimated income taxes for the U. S. Steel Group
is based on tax rates and amounts which recognize management's best estimate of
current and deferred tax assets and liabilities.  The income tax provision for
the third quarter and first nine months of 1994 included a one-time $32 million
deferred tax benefit (see Note 7 to the U. S. Steel Group financial statements).
The third quarter 1993 income tax provision included a $20 million favorable
effect associated with an increase in the federal income tax rate from 34% to
35%.  This credit reflected a $15 million remeasurement of deferred federal
income tax assets as of January 1, 1993, and a $5 million tax credit related to
1993 pretax losses.

     Third quarter 1994 steel shipments of 2.6 million tons and raw steel
production of 2.9 million tons increased 3% and 2%, respectively, from the same
quarter of 1993.  Steel shipments and raw steel production in the first nine
months of 1994 totaled 7.7 million tons and 8.5 million tons, respectively.
These represented increases of 5% and 2%, respectively, from the same period in
1993.  Raw steel capability utilization averaged approximately 95% in the third
quarter and first nine months of 1993 and 1994.

     Favorable steel market conditions are presently expected to continue into
1995.  U. S. Steel's order book remains healthy and further price increases on
most

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

steel products have been announced effective January 1, 1995.  Shipments in the
fourth quarter of 1994 are expected to be higher than third quarter shipments as
some customers may increase purchases prior to these price increases.  During
the first quarter of 1995, operating rates are expected to be reduced by planned
blast furnace outages at Gary Works and Fairfield Works.

     The domestic steel industry has been adversely affected by unfairly traded
imports.  Steel imports to the United States accounted for an estimated 19%, 17%
and 18% of the domestic steel market in 1993, 1992 and 1991, respectively.
Following the decision by the International Trade Commission ("ITC") in July
1993, levels of imported steel increased with imports accounting for an
estimated 22% of the domestic steel market in the fourth quarter of 1993 and 24%
in the first eight months of 1994.  However, market prices for steel products
have generally remained firm because of strong demand, and USX has successfully
obtained some price increases.  While USX is unable to predict the effect the
ITC decision may have on the business or results of operations of the U. S.
Steel Group, the higher levels of imported steel may ultimately have an adverse
effect on product prices and shipment levels.

     On June 30, 1994, in conjunction with six other domestic producers, USX
filed antidumping and countervailing duty cases with the U.S. Department of
Commerce and the ITC asserting that seven foreign nations have engaged in unfair
trade practices with respect to the export of oil country tubular goods
("OCTG").  On August 15, 1994, the ITC unanimously issued a preliminary ruling
that there is a reasonable indication that U. S. Steel and six other domestic
OCTG producers have been injured by illegal subsidies and dumping.  Under the
applicable statute, the U. S. Department of Commerce must now issue its
preliminary determination with respect to the unfair trade practices alleged by
the petitioners.  The statute provides for the determination to be made in
December 1994 subject to a possible extension to January 1995.  USX will file
additional antidumping and countervailing duty petitions if unfairly traded
imports adversely impact, or threaten to adversely impact, the results of the U.
S. Steel Group.

     In October 1994, the U. S. Steel Group entered into a letter of intent with
Nucor Corporation and Praxair, Inc. for establishment of a joint venture to
develop a new technology to produce steel directly from iron carbide.  The
parties would initially conduct a feasibility study of the iron carbide to steel
process.  If the feasibility study proves successful, the joint venture company
would construct a demonstration plant to develop and evaluate the commercial
feasibility of the steelmaking process.

Cash Flows
- ----------
     Net cash used in operating activities was $70 million in the first nine
months of 1994, compared with net cash provided from operating activities of
$171 million in the same period of 1993.  The decrease primarily reflected
payments of $367 million in 1994 to settle substantially all of the remaining
judgments from the B&LE litigation.  In addition, net cash provided from
operating activities in the first nine months of 1993 benefited from a $103
million favorable effect from the use of available funds from previously
established insurance reserves to pay for certain active and retired employee
insurance benefits.  Excluding the 1994 payments and the

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

1993 favorable effect, net cash flows from operating activities in the first
nine months of 1994 improved $229 million from the same period in 1993.

     Cash from the disposal of assets totaled $16 million in the first nine
months of 1994, compared with $154 million in the first nine months of 1993.
The 1993 proceeds mainly reflected the sales of the Cumberland coal mine and
investments in an insurance company and a foreign manganese mining affiliate.

     Financial obligations increased by $23 million in the first nine months of
1994, primarily reflecting the U. S. Steel Group's net cash flows from operating
and investing activities, partially offset by proceeds from the issuance of
Steel Stock.  These financial obligations consist of the U. S. Steel Group's
portion of USX debt and preferred stock of a subsidiary attributed to all three
groups, as well as debt and financing agreements specifically attributed to the
U. S. Steel Group.

     In February 1994, USX sold 5,000,000 shares of Steel Stock to the public
for net proceeds of $201 million which were reflected in their entirety in the
U. S. Steel Group financial statements.

     The U. S. Steel Group engages in hedging activities in the normal course of
its business.  Commodity swaps are used to hedge exposure to price fluctuations
relevant to the purchase of natural gas.  While hedging activities are generally
used to reduce risks from unfavorable price movements, they also may limit the
opportunity to benefit from favorable movements.  The U. S. Steel Group's
hedging activities have not been significant in relation to its overall business
activity.  Management believes that its use of hedging instruments will not have
a material effect on the financial position, liquidity or results of operations
of the U. S. Steel Group.

     For discussion of USX's liquidity and capital resources, see USX
Consolidated Management's Discussion and Analysis of Financial Condition and
Results of Operations.

Capital Expenditures
- --------------------
     U. S. Steel Group capital expenditures for property, plant and equipment in
the third quarter and first nine months of 1994 were $63 million and $171
million, respectively, compared with $54 million and $136 million, respectively,
in the same periods in 1993.

     For the year 1994, capital expenditures are expected to total approximately
$250 million, compared with $198 million in 1993.

     Contract commitments for capital expenditures at September 30, 1994, were
$94 million, compared with $105 million at year-end 1993.

Environmental Matters, Contingencies and Commitments
- ----------------------------------------------------
     The U. S. Steel Group has incurred and will continue to incur substantial
capital, operating and maintenance, and remediation expenditures as a result of

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

environmental laws and regulations.  In recent years, these expenditures have
been mainly for process changes in order to meet Clean Air Act obligations,
although ongoing compliance costs have also been significant.  To the extent
these expenditures, as with all costs, are not ultimately reflected in the
prices of the U. S. Steel Group's products and services, operating results will
be adversely affected.  The U. S. Steel Group believes that all of its domestic
competitors are subject to similar environmental laws and regulations.  However,
the specific impact on each competitor may vary depending on a number of
factors, including the age and location of their operating facilities and their
production methods.

     USX has been notified that it is a potentially responsible party ("PRP") at
35 waste sites related to the U. S. Steel Group under the Comprehensive
Environmental Response, Compensation and Liability Act ("CERCLA") as of
September 30, 1994.  In addition, there are 25 sites related to the U. S. Steel
Group where USX has received information requests or other indications that USX
may be a PRP under CERCLA but where sufficient information is not presently
available to confirm the existence of liability or make any judgment as to the
amount thereof.  There are also 36 additional sites related to the U. S. Steel
Group where remediation is being sought under other environmental statutes, both
federal and state, or where private parties are seeking remediation through
discussions or litigation.  At many of these sites, USX is one of a number of
parties involved and the total cost of remediation, as well as USX's share
thereof, is frequently dependent upon the outcome of investigations and remedial
studies.  The number of waste sites in and of itself does not necessarily
represent a relevant measure of liability because the nature and extent of
environmental concerns vary from site to site, and USX's share of responsibility
varies significantly.

     The U. S. Steel Group accrues for environmental remediation activities when
the responsibility to remediate is probable and the amount of associated costs
is reasonably determinable.  As environmental remediation matters proceed toward
ultimate resolution or as additional remediation obligations arise, charges in
excess of those previously accrued may be required.

     USX is the subject of, or a party to, a number of pending or threatened
legal actions, contingencies and commitments relating to the U. S. Steel Group
involving a variety of matters, including laws and regulations relating to the
environment (see Note 12 to the U. S. Steel Group financial statements for a
discussion of certain of these matters).  The ultimate resolution of these
contingencies could, individually or in the aggregate, be material to the U. S.
Steel Group financial statements.  However, management believes that USX will
remain a viable and competitive enterprise even though it is possible that these
contingencies could be resolved unfavorably to the U. S. Steel Group.  See
discussion of Liquidity and Capital Resources in USX Consolidated Management's
Discussion and Analysis of Financial Condition and Results of Operations.

                         DELHI GROUP OF USX CORPORATION
                     SELECTED NOTES TO FINANCIAL STATEMENTS
                     --------------------------------------
                                   (Unaudited)
                                        

 1.  The information furnished in these financial statements is unaudited but,
    in the opinion of management, reflects all adjustments necessary for a fair
    presentation of the results for the periods covered.  All such adjustments
    are of a normal recurring nature unless disclosed otherwise.  These
    financial statements, including selected notes, have been prepared in
    accordance with the applicable rules of the Securities and Exchange
    Commission and do not include all of the information and disclosures
    required by generally accepted accounting principles for complete financial
    statements.  Additional information is contained in the USX Annual Report
    on Form 10-K for the year ended December 31, 1993.

 2.  The financial statements of the Delhi Group include the financial position,
     results of operations and cash flows for the business of Delhi Gas Pipeline
     Corporation (DGP) and certain other subsidiaries of USX, and a portion of
     the corporate assets and liabilities and related transactions which are not
     separately identified with ongoing operating units of USX.  These financial
     statements are prepared using amounts included in the USX consolidated
     financial statements.  Corporate amounts reflected in these financial
     statements are determined based upon methods which management believes to
     be reasonable.  The accounting policies applicable to the preparation of
     the financial statements of the Delhi Group may be modified or rescinded in
     the sole discretion of the Board of Directors of USX (Board), although the
     Board has no present intention to do so.  The Board may also adopt
     additional policies depending on the circumstances.

     The Board has designated 14,003,205 shares of USX-Delhi Group Common Stock
     (Delhi Stock) to represent 100% of the common stockholders' equity value of
     USX attributable to the Delhi Group as of September 30, 1994.  The Delhi
     Fraction is the percentage interest in the Delhi Group represented by the
     shares of Delhi Stock that are outstanding at any particular time and,
     based on 9,437,891 outstanding shares at September 30, 1994, is
     approximately 67%.  The Marathon Group financial statements reflect a
     Retained Interest in the Delhi Group of approximately 33%.

     Although the financial statements of the Delhi Group, the Marathon Group
     and the U. S. Steel Group separately report the assets, liabilities
     (including contingent liabilities) and stockholders' equity of USX
     attributed to each such group, such attribution of assets, liabilities
     (including contingent liabilities) and stockholders' equity among the Delhi
     Group, the Marathon Group and the U. S. Steel Group for the purpose of
     preparing their respective financial statements does not affect legal title
     to such assets and responsibility for such liabilities.  Holders of Delhi
     Stock, USX-Marathon Group Common Stock (Marathon Stock) and USX-U. S. Steel
     Group Common Stock (Steel Stock) are holders of common stock of USX, and
     continue to be subject to all the risks associated with an investment in
     USX and all of its businesses and liabilities.  Financial impacts arising
     from one Group that affect the overall cost of USX's capital could affect
     the results of operations and financial condition of other groups.  In
     addition, net losses of any Group, as well as dividends and distributions
     on any class of USX Common Stock or series of preferred stock and
     repurchases of any class of USX Common Stock or series of preferred stock
     at prices in excess of par or stated value, will reduce the funds of USX
     legally available for payment of dividends on all classes of common stock.
     Accordingly, the USX consolidated financial information should be read in
     connection with the Delhi Group financial information.

                         DELHI GROUP OF USX CORPORATION
               SELECTED NOTES TO FINANCIAL STATEMENTS (Continued)
               --------------------------------------------------
                                   (Unaudited)
                                        

 3.  The method of calculating net income (loss) per share for the Delhi Stock,
    Marathon Stock, and Steel Stock reflects the Board's intent that the
    separately reported earnings and surplus of the Delhi Group, the Marathon
    Group and the U. S. Steel Group, as determined consistent with the USX
    Certificate of Incorporation, are available for payment of dividends to the
    respective classes of stock, although legally available funds and
    liquidation preferences of these classes of stock do not necessarily
    correspond with these amounts.

     Net income (loss) per share is calculated by adjusting net income (loss)
     for dividend requirements of preferred stock and income applicable to the
     Retained Interest and is based on the weighted average number of common
     shares outstanding plus common stock equivalents, provided they are not
     antidilutive.  Common stock equivalents result from assumed exercise of
     stock options and surrender of stock appreciation rights associated with
     stock options, where applicable.

     Fully diluted net income (loss) per share assumes exercise of stock options
     and surrender of stock appreciation rights, provided, in each case, the
     effect is not antidilutive.

 4.  Inventories are carried at lower of average cost or market.

 5.  In the first nine months of 1994, restructuring charges totaling $39.9
     million were recorded for the write-down of assets to estimated net
     realizable value related to the planned disposition of certain nonstrategic
     gas gathering and processing assets and other investments.  Charges of
     $37.4 million were included in operating costs and $2.5 million included in
     other income in the second quarter of 1994.

 6.  Other income in the first nine months of 1993 included a pretax gain of
     $2.9 million from disposal of assets ($.8 million in the third quarter).
     The disposal of assets included a pretax gain of $1.6 million from the
     first quarter 1993 sale of a 25% interest in a natural gas transmission
     partnership in the first quarter. The tax provision for estimated U.S.
     income taxes in the first nine months of 1993 included an unfavorable tax
     effect associated with the sale of the partnership interest, which resulted
     in a $1.2 million net loss on the transaction.

                                   (Unaudited)
                                        

 7.  The financial statement provision for estimated income taxes and related
     tax payments or refunds have been reflected in the Delhi Group, the
     Marathon Group and the U. S. Steel Group financial statements in accordance
     with USX's tax allocation policy for such groups.  In general, such policy
     provides that the consolidated tax provision and related tax payments or
     refunds are allocated among the Delhi Group, the Marathon Group and the U.
     S. Steel Group for group financial statement purposes, based principally
     upon the financial income, taxable income, credits, preferences and other
     amounts directly related to the respective groups.

     The provision (credit) for estimated income taxes for the Delhi Group is
     based on tax rates and amounts which recognize management's best estimate
     of current and deferred tax assets and liabilities.  Differences between
     the combined interim tax provisions of the Delhi, the Marathon and the U.
     S. Steel Groups and USX consolidated are allocated to each group based on
     the relationship of the individual group provisions to the combined interim
     provisions.

     The third quarter 1993 income tax provision included a $4.4 million charge
     associated with an increase in the federal income tax rate from 34% to 35%.
     This charge reflected a $4.1 million remeasurement of deferred federal
     income tax liabilities as of January 1, 1993, and $.3 million effect
     related to taxes on 1993 pretax income.

 8.  In the first quarter of 1994, USX Capital LLC, a wholly owned subsidiary of
     USX, sold $250 million of 8-3/4% Cumulative Monthly Income Preferred Shares
     (MIPS).  In accordance with the USX policy of managing most financial
     activities on a centralized, consolidated basis, the proceeds from issuance
     of the MIPS and the related financial costs (which are included in interest
     and other financial costs) were attributed to all three groups in
     proportion to their respective participation in USX centrally managed
     financing activities.

 9.  Certain of the Delhi Group accounts receivable are sold in combination with
     the Marathon Group accounts receivable under a limited recourse agreement.
     Payments are collected from the sold accounts receivable; the collections
     are reinvested in new accounts receivable for the buyers; and a yield,
     based on short-term market rates, is transferred to the buyers.  At
     September 30, 1994, the balance of the Delhi Group's sold accounts
     receivable that had not been collected was $66.8 million.  In the event of
     a change in control of USX, as defined in the agreement, the Delhi Group
     may be required to forward payments collected on sold Delhi Group accounts
     receivable to the buyers.

10.  USX is the subject of, or a party to, a number of pending or threatened
     legal actions, contingencies and commitments relating to the Delhi Group
     involving a variety of matters, including laws and regulations relating to
     the environment.  Certain of these matters are discussed below.  The
     ultimate resolution of these contingencies could, individually or in the
     aggregate, be material to the Delhi Group financial statements.  However,
     management believes that USX will remain a viable and competitive
     enterprise even though it is possible that these contingencies could be
     resolved unfavorably to the Delhi Group.  See discussion of Liquidity and
     Capital Resources in USX Consolidated Management's Discussion and Analysis
     of Financial Condition and Results of Operations.

10.  (Continued)

     The Delhi Group is subject to federal, state and local laws and regulations
     relating to the environment.  These laws generally provide for control of
     pollutants released into the environment and require responsible parties to
     undertake remediation of hazardous waste disposal sites.  Penalties may be
     imposed for noncompliance.  Expenditures for remediation and penalties have
     not been material.

     For a number of years, the Delhi Group has made capital expenditures to
     bring existing facilities into compliance with various laws relating to the
     environment.  In 1993 and 1992, such capital expenditures totaled
     approximately $4.5 million and $3.0 million, respectively.  The Delhi Group
     anticipates making additional such expenditures in the future; however, the
     exact amounts and timing of such expenditures are uncertain because of the
     continuing evolution of specific regulatory requirements.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

     The Delhi Group includes Delhi Gas Pipeline Corporation and certain other
subsidiaries of USX which are engaged in the purchasing, gathering, processing,
transporting and marketing of natural gas.  The following discussion should be
read in conjunction with the third quarter 1994 USX consolidated financial
information and the Delhi Group financial statements and selected notes.

Results of Operations
- ---------------------
     The Delhi Group had a net loss of $1.0 million, or $.07 per share, in the
third quarter of 1994, compared with a net loss of $0.7 million, or $.05 per
share, in the third quarter of 1993.  The Delhi Group had a net loss of $32.2
million, or $2.32 per share, in the first nine months of 1994, compared with net
income of   $10.1 million, or $.71 per share, in the first nine months of 1993.

     Sales totaled $133.7 million in the third quarter of 1994, compared with
$131.3 million in the third quarter of 1993. The improvement primarily reflected
increased volumes from the Delhi Group's trading business and from spot market
sales, partially offset by lower average prices for natural gas.  Sales totaled
$424.3 million in the first nine months of 1994, compared with $391.3 million in
the first nine months of 1993.  The improvement primarily reflected increased
volumes from the Delhi Group's trading business and from spot market sales,
partially offset by lower average prices for natural gas and a decline in
average prices for natural gas liquids ("NGLs").

     The Delhi Group had operating income of $1.8 million in the third quarter
of 1994, compared with $7.8 million in the third quarter of 1993.  Operating
income in the third quarter of 1994 included a $0.8 million favorable effect of
the reversal of prior-period accruals related to the settlement of certain
contractual matters.   Operating income in the third quarter of 1993 included a
$0.8 million refund of prior years' sales taxes.  Excluding the effects of these
items, third quarter 1994 operating income declined by $6.0 million from the
third quarter of 1993.  This decrease was due primarily to lower gas sales
margin, reflecting a decline in premiums (principally from one customer,
Southwestern Electric Power Company ("SWEPCO") and lower spreads on spot market
sales.  This was partially offset by lower depreciation expense as a result of
restructuring activity, higher natural gas throughput volumes and lower average
gas processing plant feedstock (natural gas) costs.

     The Delhi Group had an operating loss of $41.7 million in the first nine
months of 1994, compared with operating income of $29.7 million in the first
nine months of 1993.  The operating loss in the first nine months of 1994
included restructuring charges of $37.4 million, expenses of $1.7 million
related to a work force reduction program, other employment-related costs of
$2.0 million, charges related to certain contractual matters of $0.3 million and
a $1.6 million favorable pretax effect of the settlement of litigation related
to a prior-year take-or-pay claim.  Operating income in the first nine months of
1993 included favorable effects of $1.8 million for the reversal of a prior-
period accrual related to a natural gas contract settlement, $0.8 million for a
refund of prior-years' sales taxes and   $0.8 million related to gas imbalance
settlements.  Excluding the effects of these items, the operating loss in the
first nine months of 1994 was $1.9 million, down $28.2 million from operating
income of $26.3 million in the first nine months of

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

1993.  This decrease was due primarily to lower gas sales margin and lower
average NGLs prices, partially offset by higher natural gas throughput volumes
and lower depreciation expense.

     In June, following a management review of the group's overall cost
structure and asset base, the USX Board of Directors authorized a plan for the
disposition of certain non-strategic assets in Arkansas, Kansas, Louisiana,
Oklahoma and Texas, including pipeline systems comprised of approximately 1,500
miles of gas pipeline and four gas processing plants.  The Delhi Group recorded
noncash pretax restructuring charges totaling $39.9 million in the second
quarter of 1994 for the write-down of these assets to estimated net realizable
value.  Charges of $37.4 million were included in operating costs and a charge
of $2.5 million was included in other income (loss).  Depreciation expense
reductions related to the restructuring totaled $3.1 million in the third
quarter of 1994; reductions are expected to total approximately $3.1 million in
the fourth quarter of 1994 and approximately $7.4 million in the year 1995.  As
of November 1, 1994, the Delhi Group had disposed of approximately one-third of
the assets authorized under the restructuring plan.  

     In addition to the restructuring charges, the Delhi Group recorded pretax
employee reorganization expenses of $1.7 million in the second quarter of 1994,
primarily reflecting employee severance and relocation costs associated with a
work force reduction program designed to realign the organization with current
business conditions.  The program affected regional and headquarters employees
in various job functions, and is expected to result in an annual reduction in
employment costs of approximately $5 million, following full implementation.

     The Delhi Group attempts to sell all of the natural gas available on its
systems each month.  Natural gas volumes not sold to its premium markets are
typically sold in the spot market, generally at lower average unit margins than
those realized from premium sales.  Gas sales margin in the first nine months of
1994 declined from the first nine months of 1993 due primarily to lower premiums
from SWEPCO and other customers and a decline in margins from spot market sales.
Gas sales margins from SWEPCO declined by $12.0 million from the first nine
months of 1993 (of which $4.9 million occurred in the third quarter), reflecting
the terms of a new natural gas purchase agreement providing for market sensitive
prices beginning in February 1994.  The decline in margins from spot market
sales mainly reflected declines in natural gas prices.

     Transportation throughput in the third quarter and first nine months of
1994 declined by 16% and 17%, respectively, from the comparable 1993 periods,
primarily due to increased competition and natural production declines on third-
party wells.

     Natural gas volumes from trading sales totaled 117.4 million cubic feet per
day in the third quarter of 1994.  The Delhi Group anticipates continued
expansion of its trading business in the future.  The trading business involves
the purchase of natural gas from sources other than wells directly connected to
the Delhi Group's systems, and the subsequent sale of like volumes.  Unit
margins earned in the trading business are usually significantly less than those
earned on system sales.

     The Delhi Group monitors the economics of removing NGLs from the gas stream
for processing on an ongoing basis to determine the appropriate level of each
gas

plant's operation.  Unit margins from gas processing are a function of the sales
prices for NGLs, which tend to fluctuate with changes in the price of crude oil,
and the cost of natural gas feedstocks from which NGLs are extracted.  Due to
unfavorable economics in late 1993 and early 1994, the Delhi Group chose not to
fully process some gas, resulting in a 22% decline in first quarter 1994 NGLs
sales volumes as compared with the first quarter of 1993.  Second and third
quarter 1994 average NGLs sales volumes and gas processing gross margins
improved significantly from the depressed first quarter 1994 levels.  Despite
this improvement, average NGLs sales volumes and gas processing gross margin in
the first nine months of 1994 were lower than in the comparable 1993 period by
8% and 49%, respectively.

     Third quarter 1994 other income declined by $1.0 million from the third
quarter of 1993.  Other income in the third quarter of 1993 included a $0.8
million pretax gain on the sale of nonstrategic Colorado gas gathering systems.
Other loss of $1.3 million in the first nine months of 1994 included a $2.5
million restructuring charge.  Other income of $4.9 million in the first nine
months of 1993 included a $1.6 million pretax gain on the sale of the Delhi
Group's 25% interest in a natural gas transmission partnership and a $0.9
million favorable pretax effect of a prior asset acquisition, in addition to the
previously mentioned $0.8 million gain on the sale of Colorado gas gathering
systems.

     The provision for estimated U.S. income taxes is based on tax rates and
amounts which recognize management's best estimate of current and deferred tax
assets and liabilities.  The third quarter 1993 income tax provision included a
$4.4 million unfavorable effect of remeasuring income tax liabilities associated
with an increase in the federal income tax rate from 34% to 35%.  This charge
reflected a $4.1 million remeasurement of deferred federal income tax
liabilities as of January 1, 1993, and a $0.3 million effect related to taxes on
1993 pretax income.  The income tax provision for the first nine months of 1993
included a $2.8 million unfavorable effect associated with the sale of the Delhi
Group's interest in a natural gas transmission partnership, in addition to the
previously mentioned $4.4 million remeasurement effect.

     The Delhi Group's operating results are affected by fluctuations in natural
gas prices and demand levels in the markets that it serves.  The level of gas
sales margin is greatly influenced by the demand for premium services and the
volatility of natural gas prices.  Because the strongest demand for gas and the
highest gas sales unit margins generally occur during the winter heating season,
the Delhi Group has historically recognized the greatest portion of income from
its gas sales business during the first and fourth quarters of the year.
Quarterly levels of gas sales margin are difficult to accurately project.
However, fourth quarter 1994 gas sales margin from two contracts will be lower
than the prior-year fourth quarter by a total of approximately $5.5 million as a
result of the terms of the new natural gas purchase agreement with SWEPCO and
the expiration in August 1994 of one of the Delhi Group's contracts with Central
Power and Light Company ("CP&L"), a utility electric generator serving south
Texas.  On the basis of sales revenues, SWEPCO and CP&L, who are owned by a
common parent, were each among the Delhi Group's four largest customers for the
year 1993.

Cash Flows
- ----------
     Net cash provided from operating activities was $29.4 million in the first
nine months of 1994, up $10.9 million from the first nine months of 1993.  The

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ---------------------------------------------

effect of lower income was more than offset by a decline in income tax payments
(including settlements with other groups), favorable working capital changes
(including the collection of receivables in the first quarter relating to a
natural gas contract dispute with SWEPCO which was settled in 1994) and the
receipt of a $3.8 million advance payment under the terms of a gas purchase
contract.

     Cash provided from the disposal of assets was $4.1 million in the first
nine months of 1994, compared with $4.2 million in the first nine months of
1993.  The 1994 amount included proceeds of $3.0 million from the sale of the
North Louisiana System.  The 1993 amount included proceeds of $1.9 million from
the sale of the Delhi Group's interest in a natural gas transmission partnership
and $1.6 million from the sale of nonstrategic gas gathering systems in
Colorado.

     Financial obligations decreased by $13.3 million in the first nine months
of 1994, primarily reflecting the Delhi Group's net cash provided from operating
activities, partially offset by net cash used in investing activities.
Financial obligations consist of the Delhi Group's portion of USX debt and
preferred stock of a subsidiary attributed to all three groups.

     The Delhi Group engages in hedging activities in the normal course of its
business.  Futures contracts are used to hedge exposure to price fluctuations
relevant to the purchase or sale of natural gas.  While hedging activities are
generally used to reduce risks from unfavorable movements, they may also limit
the opportunity to benefit from favorable movements.  The Delhi Group's hedging
activities have not been significant in relation to the Group's overall business
activity.  Management believes that its use of hedging instruments will not have
a material effect on the financial position, liquidity or results of operations
of the Delhi Group.

     For discussion of USX's liquidity and capital resources, see USX
Consolidated Management's Discussion and Analysis of Financial Condition and
Results of Operations.

Capital Expenditures
- --------------------
     Delhi Group capital expenditures for property, plant and equipment totaled
$7.8 million in the third quarter of 1994, down $1.9 million from the third
quarter of 1993.  Capital expenditures in the first nine months of 1994 totaled
$21.7 million, an increase of $0.7 million from the first nine months of 1993.

     Capital expenditures in 1994 will reflect continued expenditures to connect
dedicated gas reserves by the expansion or acquisition of gas gathering,
processing and transmission assets, including those made available as a result
of current industry conditions and regulatory initiatives.  In September, the
Delhi Group announced that negotiations for the purchase of the west Texas
gathering and treating facilities of a Texas intrastate pipeline company had
been terminated.  The parties had previously announced that they had signed an
agreement in principle for the purchase of these assets by the Delhi Group
subject to execution of a definitive purchase agreement and receipt of necessary
regulatory approvals.  The level of the Delhi Group's capital spending in the
fourth quarter of 1994 will be dependent on

                  ---------------------------------------------

the timing and availability of opportunities to enhance its presence in key
operating areas.  Capital expenditures for the year 1994 are expected to be in
the range of $35 million to $40 million, compared with capital expenditures for
the year 1993 of $42.6 million.

Environmental Matters, Contingencies and Commitments
- ----------------------------------------------------
     The Delhi Group has incurred and will continue to incur capital and
operating and maintenance expenditures as a result of environmental laws and
regulations.  To the extent these expenditures, as with all costs, are not
ultimately reflected in the prices of the Delhi Group's products and services,
operating results will be adversely affected.  The Delhi Group believes that
substantially all of its competitors are subject to similar environmental laws
and regulations.  However, the specific impact on each competitor may vary
depending on a number of factors, including the age and location of their
operating facilities and their production processes.

     USX is the subject of, or a party to, a number of pending or threatened
legal actions, contingencies and commitments relating to the Delhi Group
involving a variety of matters, including laws and regulations relating to the
environment.  The ultimate resolution of these contingencies could, individually
or in the aggregate, be material to the Delhi Group financial statements.
However, management believes that USX will remain a viable and competitive
enterprise even though it is possible that these contingencies could be resolved
unfavorably to the Delhi Group.  See discussion of Liquidity and Capital
Resources in USX Consolidated Management's Discussion and Analysis of Financial
Condition and Results of Operations.

Item 1.  LEGAL PROCEEDINGS

The following developments occurred during the the three months ended
September 30, 1994, with respect to certain matters discussed in USX's Form 10-K
for the year ended December 31, 1993:

   U. S. Steel Group

          (a)  Inland Steel Patent Litigation

               On July 5, 1994, the Patent Office issued a decision rejecting
               all claims of the Inland patents.  Inland is expected to file a
               response to this decision in November 1994 and has the right to
               appeal the Patent Office decision to the Patent Office Board of
               Appeals.

          (b)  Securities Litigation

               On August 8, 1994, the U.S. District Court denied the Company's
               motion to dismiss, and discovery is proceeding.

          (c)  Environmental Proceedings - Gary Works

               In September 1994, the U.S. Environmental Protection Agency (the
               "EPA") informed USX of its intent to demand civil penalties for
               alleged violations of the Clean Water Act at USX's Gary Works in
               Gary, Indiana.  USX and the EPA have been engaged in ongoing
               discussions concerning water-related matters involving Gary
               Works, including the dredging of the Grand Calumet River.  The
               penalty discussions are a part of those ongoing discussions.  The
               initial penalty amount presented by the EPA was approximately $12
               million.   USX is continuing its discussion with the EPA
               concerning the penalty amount.
