                        UNITED STATES STEEL CORPORATION

     We are the largest integrated steel producer in North America. We have a
broad and diverse mix of products and customers. We make, sell and transport a
wide range of value-added sheet to customers with demanding technical
applications in the automotive, appliance, distribution, industrial machinery,
and construction industries. We are one of the leading steel sheet suppliers to
the North American automotive and appliance industries, the largest integrated
flat-rolled producer in Central Europe, the largest domestic producer of
seamless oil country tubular goods and one of the two largest producers of tin
mill products in North America. We currently have annual steel-making capability
of 17.8 million tons through our four integrated steel mills. In 2001, we
shipped 13.5 million tons of steel globally and generated revenues of $6,286
million.

     We operate three integrated steel mills in North America and produce, sell
and transport a variety of sheet, tin, plate and tubular products, as well as
coke, iron ore and coal. We have annual steel-making capability in the U.S. of
12.8 million tons through Gary Works in Indiana, Mon Valley Works in
Pennsylvania and Fairfield Works in Alabama. We operate finishing facilities at
six locations in those three states and in Ohio. We produce most of the iron ore
and coke and a portion of the coal we use as raw materials in our steel-making
process. We also participate in the real estate, resource management, and
engineering and consulting services businesses. We have a significant market
presence in each of our major product areas and have long-term relationships
with many of our major customers.

     In November 2000, we acquired U. S. Steel Kosice, s.r.o. ("USSK"),
headquartered in Kosice in the Slovak Republic, the largest integrated
flat-rolled producer in Central Europe. USSK has annual steel-making capability
of 5.0 million tons and produces and sells sheet, tin, tubular, plates and
specialty products, as well as coke. The acquisition of USSK has enabled us to
establish a low-cost manufacturing base in Europe and positioned us to serve our
global customers.

     On December 31, 2001, we completed our separation from the former USX
Corporation, now known as Marathon Oil Corporation.

                   STEEL INDUSTRY CONDITIONS AND OUR POSITION

     - Steel prices are rising.  U.S. Steel has announced domestic price
       increases of $50 per ton for hot-rolled products and $70 per ton for
       cold-rolled and coated products for spot market sales on or after May 1,
       2002. Several of our domestic competitors have also announced increases
       for spot market sales. In general, domestic spot market hot-rolled prices
       quoted for the third quarter of this year have increased by over $100 per
       ton over those realized in the fourth quarter of 2001. USSK announced two
       price increases of 20 euro per mt each on hot-rolled, cold-rolled and
       galvanized products, effective for new orders for shipment after April 1,
       2002 and June 1, 2002.

                                       S-1


     - Significant positive leverage to rising steel prices.  Our earnings are
       highly correlated to steel prices and price increases positively impact
       our net income. Approximately 60% of our domestic sheet products are sold
       under terms quoted for less than 12 months. We estimate that a $10 per
       ton annualized increase in spot domestic sheet prices would increase our
       operating income by approximately $40 million based on projected
       shipments for 2002.

     - Domestic steel capacity has been reduced.  Domestic hot strip mill
       capacity declined by approximately 20% in 2001. This decline has resulted
       primarily from the recent shutdowns of several steel producers. Some of
       these assets have been acquired and plans have been announced to restart
       a substantial portion of this capacity. It typically takes several months
       to restart integrated steelmaking capacity. In addition, there has been
       no significant new investment in domestic sheet capacity over the last
       few years.

     - Our utilization rates have improved significantly.  During January, we
       restarted two domestic blast furnaces that were idled in 2001 due to
       business conditions and are now operating all seven of our domestic blast
       furnaces. Raw steel capability utilization for our domestic facilities
       increased to 92% in the first quarter of 2002, up from 83% in the same
       quarter a year ago, and up from 67% in the fourth quarter of 2001. With
       all three blast furnaces operational beginning in late January, USSK's
       first quarter raw steel capability utilization was 74%, compared with 77%
       and 66%, respectively, in 2001's first and fourth quarters.

     - Government trade initiatives should further strengthen our industry and
       our business.  On March 5, 2002, President Bush announced his decision in
       response to the prior finding of the International Trade Commission under
       Section 201 of the Trade Act of 1974 that imports were a substantial
       cause of serious injury to the domestic steel industry. Slab imports are
       subject to a quota of 5.4 million tons in the first year on product
       shipped from countries other than Canada and Mexico, with excess imports
       subject to a tariff of 30%. The annual quota increases to 5.9 million
       tons in the second year and 6.4 million tons in the third year. Imports
       of finished carbon and alloy steel products (hot-rolled, cold-rolled and
       coated sheet, as well as plate and tin mill products) from developed
       countries other than Canada and Mexico are subject to a 30% tariff in the
       first year, decreasing to 24% and 18% in the second and third years,
       respectively.

                             COMPETITIVE STRENGTHS

     We believe we have a strong competitive position for the following reasons:

     - Strong market position.  We are the largest integrated steel producer in
       North America. We produce a diverse array of high value-added products.
       We are a major supplier to each of the "Big 3" automotive companies and a
       growing supplier to foreign automotive companies with manufacturing
       facilities in the United States. We are one of the two largest suppliers
       of carbon sheet product to the North American automotive and appliance
       industries. In addition, we are the largest domestic producer of seamless
       oil country tubular goods, one of the two largest tin mill product
       producers in North America and the largest integrated flat-rolled
       producer in Central Europe. Our size, geographic and product diversity
       and global market position enable us to serve the needs of our global
       customers.

     - Modern, competitive facilities.  Over the past five years, we have
       invested over $1.4 billion in modernizing and upgrading our facilities,
       which we believe are well maintained and globally competitive.

     - Sound financial position with sufficient liquidity to meet demands of the
       business.  As of March 31, 2002, we had $496 million of available
       liquidity in the form of credit facilities, a receivables sales program
       and cash. Our market capitalization as of May 14, 2002 was $1.7 billion.

     - Funded pension obligations.  Unlike many of our domestic integrated
       competitors, we do not expect to have any significant near-term funding
       requirements with respect to retiree pension obligations because of our
       fully-funded pension plans. The fair value of the assets of our pension
       plans exceeded

                                       S-2


       benefit obligations by $1.2 billion at December 31, 2001. In addition, we
       have over $700 million in trusts for retirees that can be used to reduce
       near-term retiree health care and life insurance benefit payments.

                                    STRATEGY

     We believe we can increase shareholder value through the following
initiatives:

     - Focus on growing our higher value-added domestic activities.  We are
       actively pursuing a value-added strategic growth agenda by attempting to
       acquire selected value-added facilities that may become available with
       the potential consolidation and restructuring of the domestic integrated
       steel industry. Concurrently, we expect to reduce our investment and
       exposure to domestic raw materials and raw steelmaking. The margins on
       higher value-added products, where superior quality and service are of
       critical importance, exceed those of the commodity grades, and the number
       of producers that make them is more limited.

     - Continue to expand our globally competitive operations.  Through the
       acquisition of USSK in the Slovak Republic, we have established a
       low-cost manufacturing base in Central Europe. With this action, we
       initiated a major offshore expansion and a strategy to follow many of our
       customers into the European market. Our objective is to advance USSK to
       become a leader among European steel producers and the prime supplier of
       flat-rolled steel products to the growing Central European market. USSK's
       success in 2001 should enable us to compete effectively in steel industry
       consolidations, restructurings, privatizations and strategic partnerships
       in Central Europe as suitable opportunities become available. On March 8,
       2002, USSK announced that it had entered into a conversion and tolling
       agreement and a facility management agreement with Sartid a.d.
       ("Sartid"), an integrated steel company with facilities located in
       Smederevo and Sabac in the Republic of Serbia. The tolling agreement
       provides for the conversion of slabs into hot-rolled bands and
       cold-rolled full hard into tin-coated products. USSK will retain
       ownership of these materials and will market the hot-rolled bands and
       finished tin products in its own distribution system. The facility
       management agreement permits USSK, or an affiliated company, to have
       management oversight of Sartid's tin processing facilities at Sabac. In
       addition, USSK, the Government of the Republic of Serbia and Sartid have
       signed a letter of intent that provides USSK with the opportunity to
       explore possibilities for involvement in the restructuring of Sartid.

     - Continuously reduce costs.  We have a strong focus on continuous cost
       improvement at all of our locations. In our North American operations, we
       have targeted savings of $10 per ton per year over the next three years,
       which should result in annual operating savings of over $300 million by
       2004. At USSK, the program we initiated last year successfully reduced
       costs by $20 per mt in 2001, and we have initiated a new program to
       further reduce costs by an additional $10 per mt in 2002. We are
       currently on target to achieve our 2002 savings.

     - Strengthen our financial position.  We are committed to improving our
       balance sheet and further increasing our financial flexibility. The
       successful execution of our business strategy and cost reduction
       initiatives, coupled with the recovery of the markets we serve, should
       generate increased cash flows and improve our financial results. This
       should enable us to improve our capital structure and, over time, raise
       our credit ratings.

                               RECENT DEVELOPMENT

     On April 10, 2002, we announced that we had signed a letter of intent to
sell all of the coal and related assets associated with U. S. Steel Mining
Company's West Virginia and Alabama mines. The sale, which involves cash
consideration and is subject to several contingencies, is expected to result in
a pre-tax gain, excluding the potential recognition of the present value of
obligations related to a multiemployer health care benefit plan created by the
Coal Industry Retiree Health Benefit Act of 1992, which were broadly estimated
to be $76 million at March 31, 2002.

                   SUMMARY CONSOLIDATED FINANCIAL INFORMATION

     Prior to December 31, 2001, the businesses of United States Steel comprised
an operating unit of Marathon. Marathon had two outstanding classes of common
stock: USX-Marathon Group common stock, which was intended to reflect the
performance of Marathon's energy business, and USX-U. S. Steel Group common
stock ("Steel Stock"), which was intended to reflect the performance of
Marathon's steel business. On December 31, 2001, United States Steel was
capitalized through the issuance of 89.2 million shares of common stock to
holders of Steel Stock in exchange for all outstanding shares of Steel Stock on
a one-for-one basis (the "Separation").

     The following table sets forth summary financial data for United States
Steel. Consolidated balance sheet data as of December 31, 2001 and March 31,
2002 and statement of operations data for the first quarter ended March 31, 2002
reflect United States Steel as a separate, stand-alone entity. All other balance
sheet and statement of operations data in the table below represent a carve-out
presentation of the businesses comprising United States Steel, and are not
intended to be a complete presentation of the financial position or results of

(1) Consists of revenues, dividend and investee income (loss), net gains on
    disposal of assets, gain on investee stock offering and other income (loss).

(2) Earnings per share for the first quarter ended March 31, 2002 is based on
    the weighted average outstanding common shares during the quarter. Earnings
    per share for all other periods presented is based on the outstanding common
    shares at December 31, 2001 as a result of the Separation and the initial
    capitalization of United States Steel on that date.

(3) Dividends paid per share for all periods presented, except for the first
    quarter ended March 31, 2002, represents amounts paid on USX-U. S. Steel
    Group common stock.

(4) The increase in equity and the decrease in long-term debt, preferred stock
    of subsidiary and trust preferred securities from December 31, 2000 to 2001
    and from March 31, 2001 to 2002 were primarily due to transactions related
    to the Separation, including the $900 million value transfer. The increase
    in long-term debt from December 31, 1999 to 2000 was primarily due to cash
    used in operating activities of $627 million (including $500 million in
    elective funding to a voluntary employee benefit trust) and the $325 million
    of debt included in the acquisition of USSK.

                                USE OF PROCEEDS

     We estimate the net proceeds from this offering at the public offering
price of $18.50 per share, and after deducting underwriting discounts and
commissions and other estimated offering expenses payable by us, will be
approximately $167.2 million, or approximately $192.3 million if the
underwriters exercise their over-allotment option in full. The net proceeds will
be used for general corporate purposes, including funding working capital and
financing potential acquisitions.

STOCK PRICE RANGE AND DIVIDENDS

     Our common stock is listed on the New York Stock Exchange (the "NYSE"), the
Chicago Stock Exchange and the Pacific Exchange under the symbol "X." The NYSE
is the principal market for our common stock. Before December 31, 2001, our
businesses comprised an operating unit of USX Corporation, now named Marathon
Oil Corporation, and Marathon had a class of common stock, the USX-U. S. Steel
Group common stock, that was intended to reflect the performance of those
businesses. On December 31, 2001, each share of USX-U. S. Steel Group common
stock was converted into one share of our common stock. The following table sets
forth the range of high and low sales prices of the USX-U. S. Steel Group common
stock through December 31, 2001, and the high and low prices of our common stock

                                    BUSINESS

     United States Steel Corporation owns and operates the former steel
businesses of USX Corporation, now named Marathon Oil Corporation ("Marathon").
Prior to December 31, 2001, Marathon had two outstanding classes of common
stock: USX-Marathon Group common stock, which was intended to reflect the
performance of Marathon's energy business, and USX-U. S. Steel Group common
stock ("Steel Stock"), which was intended to reflect the performance of
Marathon's steel business. On December 31, 2001, Marathon converted each share
of Steel Stock into the right to receive one share of United States Steel
Corporation common stock (the "Separation"). United States Steel Corporation was
subsequently capitalized through the issuance of 89.2 million shares of common
stock to the holders of Steel Stock. The net assets of United States Steel
Corporation on December 31, 2001 were approximately the same as the net assets
attributed to Steel Stock at the time of the Separation, except for a $900
million value transfer in the form of additional net debt and other obligations
retained by Marathon. The terms "United States Steel" and "Corporation" when
used herein refer to United States Steel Corporation or United States Steel
Corporation and its subsidiaries, as required by the context.

     United States Steel, through its Domestic Steel segment, is engaged in the
production, sale and transportation of steel mill products, coke, taconite
pellets and coal; the management of mineral resources; the management and
development of real estate; and engineering and consulting services. Its U. S.
Steel Kosice ("USSK") segment, primarily located in the Slovak Republic,
produces and sells steel mill products and coke primarily for the Central
European market. Certain business activities are conducted through joint
ventures and partially-owned companies, such as USS-POSCO Industries
("USS-POSCO"), PRO-TEC Coating Company ("PRO-TEC"), Clairton 1314B Partnership
and Rannila Kosice, s.r.o.

     The following table sets forth the total revenues of United States Steel
for each of the last three years.

STEEL INDUSTRY BACKGROUND AND COMPETITION

     The steel industry is cyclical and highly competitive and is affected by
excess world capacity, which has restricted price increases during periods of
economic growth and led to price decreases during economic contraction. In
addition, the domestic and international steel industries face competition from
producers of materials such as aluminum, cement, composites, glass, plastics and
wood in many markets.

     United States Steel is the largest integrated steel producer in North
America and, through its subsidiary USSK, the largest integrated flat-rolled
producer in Central Europe. United States Steel competes with many domestic and
foreign steel producers. Competitors include integrated producers which, like
United States Steel, use iron ore and coke as primary raw materials for steel
production, and mini-mills, which primarily use steel scrap and, increasingly,
iron bearing feedstocks as raw materials. Mini-mills generally produce a

                                       S-8


narrower range of steel products than integrated producers, but typically enjoy
certain competitive advantages in the markets in which they compete through
lower capital expenditures for construction of facilities and non-unionized work
forces with lower employment costs and more flexible work rules. An increasing
number of mini-mills utilize thin slab casting technology to produce flat-rolled
products. Through the use of thin slab casting, mini-mill competitors are
increasingly able to compete directly with integrated producers of flat-rolled
products. Depending on market conditions, the additional production generated by
flat-rolled mini-mills could have an adverse effect on United States Steel's
selling prices and shipment levels.

     Steel imports to the United States accounted for an estimated 24%, 27% and
26% of the domestic steel market demand for 2001, 2000 and 1999, respectively.
In 2001, imports of steel pipe increased 9% and imports of hot rolled sheets
decreased 59%, compared to 2000.

     The combination of high import levels, increased domestic mini-mill
capability and reduced domestic economic activity over the last few years has
resulted in dramatically reduced domestic prices for most products and extreme
financial distress in the domestic steel industry. Since January 1998, a total
of 32 steel companies have filed for protection under Chapter 11 of the U.S.
Bankruptcy Code.

     On November 13, 2000, United States Steel joined with eight other producers
and the Independent Steelworkers Union to file trade cases against hot-rolled
carbon steel flat products from 11 countries (Argentina, India, Indonesia,
Kazakhstan, the Netherlands, the People's Republic of China, Romania, South
Africa, Taiwan, Thailand and Ukraine). Three days later, the United Steelworkers
of America ("USWA") also entered the cases as a petitioner. Antidumping ("AD")
cases were filed against all the countries and countervailing duty ("CVD") cases
were filed against Argentina, India, Indonesia, South Africa and Thailand. The
U.S. Department of Commerce ("Commerce") has found margins in all of the cases.
The International Trade Commission ("ITC") had previously found material injury
to the domestic industry in the cases against Argentina and South Africa, and,
on November 2, 2001, the ITC found material injury to the domestic industry in
the cases against the remaining countries.

     On September 28, 2001, United States Steel joined with seven other
producers to file trade cases against cold-rolled carbon steel flat products
from 20 countries (Argentina, Australia, Belgium, Brazil, China, France,
Germany, India, Japan, Korea, the Netherlands, New Zealand, Russia, South
Africa, Spain, Sweden, Taiwan, Thailand, Turkey, and Venezuela). AD cases were
filed against all the countries and CVD cases were filed against Argentina,
Brazil, France, and Korea. On November 13, 2001, the ITC determined that there
is a reasonable indication that the U.S. industry is materially injured or
threatened with material injury by reason of the imports in question. On April
29, 2002, Commerce announced preliminary determinations in the anti-dumping
cases concerning cold-rolled carbon steel flat products from the 20 countries
that are subject to those proceedings. Commerce had previously issued its
preliminary duty determinations against cold-rolled products from the four
countries that are subject to CVD proceedings. Commerce and the ITC will
continue their investigations in all of the cases.

     On March 29, 2002, we joined the other major domestic producers of oil
country tubular goods ("OCTG") in filing AD cases against imports of OCTG from
Austria, Brazil, China, Colombia, France, Germany, India, Indonesia, Romania,
South Africa, Spain, Turkey, Ukraine and Venezuela and a CVD case against
Austria. Imports of OCTG have increased more than 390% during the past two
years. Thirteen countries remained subject to the proceedings following the
withdrawal of the anti-dumping petition against Colombia. On May 10, 2002, the
ITC made a negative preliminary injury determination. This action caused the
investigations at both the ITC and Commerce to be terminated.

     United States Steel believes that the remedies provided by AD and CVD cases
are insufficient to correct the widespread dumping and subsidy abuses that
currently characterize steel imports into our country and has, therefore, urged
the U.S. government to take actions such as those in President Bush's three-part
program to address the excessive imports of steel that have been depressing
markets in the United States. The program involves: (1) negotiations with
foreign governments to eliminate inefficient excess capacity; (2) negotiations
with foreign governments to establish rules that will govern steel trade in the
future and eliminate subsidies; and (3) an investigation by the ITC under
Section 201 of the Trade Act of 1974 to determine whether steel is being
imported into the U.S. in such quantities as to be a substantial cause of
serious injury to the U.S. steel
                                       S-9


industry. United States Steel, nevertheless, intends to file additional AD and
CVD petitions against unfairly traded imports that adversely impact, or threaten
to adversely impact, the results of United States Steel.

     On March 5, 2002, President Bush announced his decision in response to the
prior finding of the ITC under Section 201 that imports were a substantial cause
of injury to the domestic steel industry. Slab imports will be subject to a
quota of 5.4 million tons in the first year on product shipped from countries
other than Canada and Mexico, with excess imports subject to a tariff of 30%.
The annual quota increases to 5.9 million tons in the second year and 6.4
million tons in the third year. Imports of finished carbon and alloy steel
products (hot-rolled, cold-rolled and coated sheet, as well as plate and tin
mill products) from developed countries will be subject to a 30% tariff in the
first year, decreasing to 24% and 18% in the second and third years,
respectively. Imports of these finished products from developing countries will
be subject to an anti-surge mechanism to ensure they do not substantially
increase their shipments from historic levels. Imports of finished flat-rolled
products from Canada and Mexico are not subject to the import remedies announced
by the President. The tariffs and quotas were effective as of March 20, 2002. An
import licensing program applicable to imports covered by the above remedies is
being implemented. The application of the remedies is subject to various
specific product exclusions. The People's Republic of China has filed a
challenge to President Bush's action with the World Trade Organization and other
nations have indicated that they also intend to do so or to take other actions
responding to the Section 201 remedies. The U.S. Trade Representative will
continue to process requests for exemption from the remedy through July 3, 2002.

     United States Steel's domestic businesses are subject to numerous federal,
state and local laws and regulations relating to the storage, handling, emission
and discharge of environmentally sensitive materials. United States Steel
believes that its major domestic integrated steel competitors are confronted by
substantially similar conditions and thus does not believe that its relative
position with regard to such other competitors is materially affected by the
impact of environmental laws and regulations. However, the costs and operating
restrictions necessary for compliance with environmental laws and regulations
may have an adverse effect on United States Steel's competitive position with
regard to domestic mini-mills and some foreign steel producers and producers of
materials which compete with steel, which may not be required to undertake
equivalent costs in their operations.

     USSK does business primarily in Central Europe and is subject to market
conditions in that area which are similar to domestic factors and also can be
influenced by matters peculiar to international marketing such as tariffs. USSK
is affected by the worldwide overcapacity in the steel industry and the cyclical
nature of demand for steel products and the sensitivity of that demand to
worldwide general economic conditions. In particular, USSK is subject to
economic conditions and political factors in Europe, which if changed could
negatively affect its results of operations and cash flow. Political factors
include, but are not limited to, taxation, nationalization, inflation, currency
fluctuations, increased regulation, and quotas, tariffs and other protectionist
measures. USSK is also subject to foreign currency exchange risks because its
revenues are primarily in euros and its costs are primarily in Slovak crowns and
U.S. dollars. On December 20, 2001, the European Commission commenced an
anti-dumping investigation concerning the import of hot-rolled coils and
hot-rolled pickled and oiled coils from Slovakia and five other countries. In
mid-February, USSK submitted a response to the anti-dumping questionnaire and an
injury submission. European Union legislation provides that the investigation
should be concluded within one year from the date of initiation, but provisional
measures may be imposed earlier.

BUSINESS STRATEGY

     United States Steel produces raw steel at Gary Works in Indiana, Mon Valley
Works in Pennsylvania, Fairfield Works in Alabama, and, through USSK, in Kosice,
Slovak Republic.

     United States Steel has responded to domestic competition resulting from
excess steel industry capability by eliminating less efficient facilities,
modernizing those that remain and entering into joint ventures, all with the
objective of focusing production on higher value-added products, where superior
quality and special characteristics are of critical importance. These products
include bake hardenable steels and coated sheets for the automobile and
appliance industries, laminated sheets for the manufacture of motors and
electrical

                                       S-10


equipment, higher strength plate products, improved tin mill products for the
container industry and oil country tubular goods. Several recent modernization
projects support United States Steel's objectives of providing value-added
products and services to customers. These projects include, for the automotive
industry -- the degasser facilities at Mon Valley Works and USSK, the second
hot-dip galvanized line at PRO-TEC, the Fairless Works galvanizing line upgrade
and the cold reduction mill upgrades at Gary Works and Mon Valley Works; for the
construction industry -- the dual coating lines at Fairfield Works and Mon
Valley Works; for the tubular market -- the Fairfield Works pipemill upgrade and
acquiring full ownership of Lorain Tubular; and for the plate market -- the heat
treat facility at the Gary Works plate mill. Also, a new pickle line was built
at the Mon Valley Works which replaced three older and less efficient
facilities. Our business strategy is to maximize our investment in high-end
finishing assets and to minimize or redeploy our investment in domestic raw
materials and hot-ends.

     Through our November 2000 purchase of USSK, which owns the steel producing
operations and related assets formerly held by VSZ, a.s. ("VSZ") in the Slovak
Republic, United States Steel initiated a major offshore expansion and followed
many of its customers into the European market. Our objective is to advance USSK
to become a leader among European steel producers and the prime supplier of
flat-rolled steel to the growing Central European market. On March 8, 2002, USSK
announced that it had entered into a conversion and tolling agreement and a
facility management agreement with Sartid a.d. ("Sartid"), an integrated steel
company with facilities located in Smederevo and Sabac in the Republic of
Serbia. The tolling agreement provides for the conversion of slabs into
hot-rolled bands and cold-rolled full hard into tin-coated products. USSK will
retain ownership of these materials and will market the hot-rolled bands and
finished tin products in its own distribution system. The facility management
agreement permits USSK, or an affiliated company, to have management oversight
of Sartid's tin processing facilities at Sabac. In addition, USSK, the
Government of the Republic of Serbia and Sartid have signed a letter of intent
that provides USSK with the opportunity to explore possibilities for involvement
in the restructuring of Sartid. We are also pursuing our globalization strategy
through our Acero Prime joint venture in Mexico. This joint venture's facility
locations allow for easy servicing and just-in-time delivery to customers
throughout Mexico.

     Effective March 1, 2001, United States Steel acquired the tin mill products
business from LTV Corporation ("LTV") for the assumption of $66 million of
employee-related liabilities. United States Steel is leasing the land and
acquired title to the buildings, facilities and inventory at LTV's former tin
mill operation in Indiana which we are operating as East Chicago Tin. United
States Steel is operating these facilities as an ongoing business and East
Chicago Tin mill employees have become United States Steel employees.

     In 2001, we permanently closed the cold rolling and tin mill operations at
Fairless Works, with a combined annual finishing capability of 1.5 million tons.
Subject to market conditions, we intend to continue operating the hot dip
galvanizing line at Fairless Works. A pretax charge of $38 million was recorded
in 2001 related to this shutdown.

     On October 30, 2001, United States Steel announced the launch of
Straightline Source ("Straightline"), the first steel distribution business
created to serve customers of all sizes who do not typically buy directly from
steel producers. Straightline's fully integrated order input system, advanced
inventory management and progressive logistics technology are networked to
create a direct buying option for processed steel products. While managing the
customer relationship, Straightline makes use of the processing capacity of a
network of qualified strategic business alliances. Straightline currently offers
processed steel products in seventeen states. Additional regional launches will
continue throughout 2002.

     On January 17, 2002, United States Steel announced that it had entered into
an Option Agreement with NKK Corporation ("NKK") of Japan. The agreement grants
United States Steel an option to purchase, either directly or through a
subsidiary, all of NKK's National Steel Corporation common stock and to
restructure a $100 million loan previously made to National Steel by an NKK
subsidiary. NKK's ownership of National Steel's common stock represents
approximately 53% of National Steel's outstanding shares. The option expires on
June 15, 2002.

     Although United States Steel has the ability to exercise the option at any
time during its term, it is United States Steel's current intent not to exercise
the option or to consummate a merger with National Steel
                                       S-11


unless a number of significant conditions are satisfied, including a substantial
restructuring of National Steel's debt and other obligations. Other significant
conditions include the resolution of key contingencies related to the
consolidation of the domestic steel industry, the financial viability of
National Steel and satisfactory general market conditions. On March 6, 2002,
National Steel filed voluntary petitions for reorganization under Chapter 11 of
the Bankruptcy Code. Any agreement with National Steel will be subject to the
approval of the bankruptcy court.

     We are actively pursuing opportunities to acquire assets that will
contribute to our value-added strategic growth agenda, while reducing our
investment and exposure to domestic raw materials and steelmaking. This strategy
builds on our announcement on December 4, 2001 regarding our support for
significant consolidation in the domestic integrated steel industry.

     In addition to the modernization of its production facilities, United
States Steel has entered into a number of joint ventures with domestic and
foreign partners to take advantage of market or manufacturing opportunities in
the sheet, tin mill, tubular, bar and plate consuming industries.

DOMESTIC STEEL

     Our domestic operations include plants that produce steel products in a
variety of forms and grades. Raw steel production was 10.1 million tons in 2001,
compared with 11.4 million tons in 2000 and 12.0 million tons in 1999. Raw steel
production averaged 79% of capability in 2001, compared with 89% of capability
in 2000 and 94% of capability in 1999. United States Steel's stated annual raw
steel production capability for Domestic Steel was 12.8 millions tons for 2001
(7.5 million at Gary Works, 2.9 million at Mon Valley Works, and 2.4 million at
Fairfield Works).

                                       S-12


     Steel shipments were 9.8 million tons in 2001, 10.8 million tons in 2000
and 10.6 million tons in 1999. United States Steel's shipments comprised
approximately 9.9% of domestic steel shipments in 2001. Exports accounted for
approximately 5% of United States Steel's domestic shipments in 2001 and 2000,
and 3% in 1999.

     Our sheet business produces hot-rolled, cold-rolled and galvanized
products. Value-added cold-rolled and galvanized products comprised 71% of our
domestic sheet shipments in 2001, including finishing performed by joint
ventures. Our sheet customer base includes automotive, appliance, service
center, industrial and construction customers. We have long standing
relationships with many of them, as do our USS-POSCO, PRO-TEC and Acero Prime
joint ventures.

     In recent years, United States Steel has made a number of key investments
directed toward the automotive industry, including upgrades to our steel making
facilities to increase our capacity for both high strength and highly formable
steels, upgrades to our Fairless galvanizing line to produce automotive quality
product and construction of an automotive technical center in Michigan. In
addition, a number of our joint ventures expanded their automotive supply
capability, most notably PRO-TEC, which, in November 1998, added 400,000 tons of
annual hot-dipped galvanized capability to bring its total to 1.0 million tons
per year.

     The tubular, tin mill products and plate businesses complement the larger
steel sheet business by producing specialized products for specific markets.

     Our tubular production facilities are located at Fairfield, Alabama;
Lorain, Ohio; and McKeesport, Pennsylvania and produce both seamless and
electric resistance weld ("ERW") tubular products. We enjoy over a 50% share of
the domestic market for seamless standard and line pipe and a 25% share of the
domestic market for oil country tubular goods ("OCTG"). With the successful
conversion in 1999 of the Fairfield piercing mill to process rounds plus the
acquisition of the remaining 50% interest in Lorain Tubular, we have the
capability to produce 1.6 million tons of tubular products in the 5 million ton
tubular markets we serve.

     With the 2001 acquisition of East Chicago Tin, we are one of the two
largest tin mill products producers in North America. We supply a full line of
tin plate and tin-free steel ("TFS") products, primarily used in the container
industry. We believe our reputation in the marketplace is enhanced through our
attention to quality and customer service reliability. We expect our acquisition
of East Chicago Tin will provide operating synergies while giving us the
opportunity to better serve our customers. We currently supply approximately 25%
of the domestic market, and, coupled with USSK's tin capability, we anticipate
being in a prime position to service customers who have a global presence. In
the fourth quarter of 2001, United States Steel recorded an intangible asset
impairment of $20 million, related to the five-year agreement for LTV to supply
United States Steel with pickled hot bands entered into in conjunction with the
acquisition of LTV's tin mill products business. This impairment was recorded
because LTV ceased operations at their plants during the quarter pursuant to a
bankruptcy court order.

     Our plate business is located within the Gary Works complex and is a major
supplier to the transportation market, and to the industrial, agricultural, and
construction markets. Our modern plate heat-treating facilities provide
customers with specialized plates for critical applications.

     United States Steel and its wholly owned subsidiary, U. S. Steel Mining
Company, LLC ("U. S. Steel Mining"), have domestic coal properties with proven
and probable bituminous coal reserves of approximately 775 million tons at
year-end 2001. The reserves are of metallurgical and steam quality in
approximately equal proportions. They are located in Alabama, Illinois, Indiana,
Pennsylvania, Tennessee and West Virginia. Approximately 94% of the reserves are
owned, and the balance are leased. The leased properties are covered by leases
which expire in 2005 and 2012. During 2000, United States Steel recorded $71
million of impairments relating to coal assets located in West Virginia and
Alabama. The impairment was recorded as a result of a reassessment of long-term
prospects after adverse geological conditions were encountered. U. S. Steel
Mining's coal production was 5.0 million tons in 2001, compared with 5.5 million
tons in 2000 and 6.2 million tons in 1999. On April 10, 2002, United States
Steel announced that it had signed a letter of intent to sell all of the coal
and related assets associated with U. S. Steel Mining's West Virginia and
Alabama mines. The sale, which involves cash consideration and is subject to
several contingencies, is expected to result in a pre-tax gain, excluding the
potential recognition of the present value of obligations related to a
multiemployer health care benefit plan created by the Coal Industry Retiree
Health Benefit Act of 1992, which were broadly estimated to be $76 million at
March 31, 2002. Upon closing of this sale, we will continue to have
approximately 640 million tons of coal reserves, but we will not operate any
coal mines.

     United States Steel controls domestic iron ore properties having proven and
probable iron ore reserves in grades subject to beneficiation processes in
commercial use by United States Steel domestic operations of approximately 695
million tons at year-end 2001, substantially all of which are iron ore
concentrate equivalents available from low-grade iron-bearing materials. All
reserves are located in Minnesota. Approximately 31% of these reserves are owned
and the remaining 69% are leased. Most of the leased reserves are covered by a
lease expiring in 2058 and the remaining leases have expiration dates ranging
from 2021 to 2026. United States Steel's iron ore operations at Mt. Iron,
Minnesota ("Minntac") produced 14.5 million tons of taconite pellets in 2001,
16.3 million tons in 2000 and 14.3 million tons in 1999. Taconite pellet
shipments were 14.9 million tons in 2001, compared with 15.0 million tons in
2000 and 15.0 million tons in 1999.

     On March 23, 2001, Transtar, Inc. ("Transtar") completed a reorganization
with its two voting shareholders, United States Steel and Transtar Holdings,
L.P. ("Holdings"), an affiliate of Blackstone Capital Partners L.P. As a result
of this transaction, United States Steel became sole owner of Transtar and
certain of its subsidiaries, including several rail and barge operations.
Holdings became owner of the other operating subsidiaries of Transtar. Transtar
provides rail and barge transportation services to a number of United States
Steel's facilities as well as other customers in the steel, chemicals, and
forest products industries.

     A subsidiary of United States Steel sells technical services worldwide to
the steel, mining, chemical and related industries. Together with its subsidiary
companies, it provides engineering and consulting services for facility
expansions and modernizations, operating improvement projects, integrated
computer systems, coal and lubrication testing and environmental projects.

     United States Steel develops real estate for sale or lease and manages
retail and office space, business and industrial parks and residential and
recreational properties. United States Steel also administers the remaining
mineral lands and timber lands of United States Steel's domestic operations and
is responsible for the lease or sale of these lands and their associated
resources, which encompass approximately 270,000 acres of surface rights and
1,500,000 acres of mineral rights in 13 states. Prior to 2002, two separate
United States Steel divisions existed for these operations. They have been
combined into one division, named USS Real Estate.

     United States Steel participates directly and through subsidiaries in a
number of joint ventures and other investments included in the Domestic Steel
segment. All of the joint ventures are accounted for under the equity method,
except for Double Eagle Steel Coating Company ("DESCO"), which is a cost-sharing
joint venture. Certain of the joint ventures and other investments are described
below, all of which are 50% owned
                                       S-15


except Republic Technologies International, LLC ("Republic"), Acero Prime and
the Clairton 1314B Partnership.

     United States Steel and Pohang Iron & Steel Co., Ltd. ("POSCO") of South
Korea participate in a joint venture, USS-POSCO, which owns and operates the
former United States Steel plant in Pittsburg, California. The joint venture
markets high quality sheet and tin products, principally in the western United
States. USS-POSCO produces cold-rolled sheets, galvanized sheets, tin plate and
tin-free steel, with hot bands principally provided by United States Steel and
POSCO. Total shipments by USS-POSCO were 836,000 tons in 2001. On May 31, 2001,
a fire damaged USS-POSCO's facilities. Damage was predominantly limited to the
cold-rolling mill. USS-POSCO maintains insurance coverage against such losses,
including coverage for business interruption. The mill resumed production in the
first quarter of 2002. Until that time, the plant used cold-rolled coils from
United States Steel and POSCO as substitute feedstock to support customer
shipments.

     United States Steel is the sole general partner of and owns a 10% equity
interest in Clairton 1314B Partnership, L.P. As general partner, United States
Steel is responsible for operating and selling coke and by-products from the
partnership's three coke batteries located at United States Steel's Clairton
Works. United States Steel's share of profits and losses is currently 1.75%,
except for United States Steel's share of depreciation and amortization, which
is 45.75%. Beginning in 2003, United States Steel's share of all profits and
losses will increase to 45.75%. The partnership at times had operating cash
shortfalls after payment of distributions to the partners in 2001 that were
funded with loans from United States Steel. As of March 31, 2002, the
partnership owed United States Steel $6 million, which was repaid in April 2002.
United States Steel may dissolve the partnership under certain circumstances
including if it is required to make equity investments or loans in excess of
$150 million to fund such shortfalls.

     United States Steel owns a 16% investment in Republic, through United
States Steel's ownership in Republic Technologies International Holdings, LLC,
which is the sole owner of Republic. Republic is a major purchaser of raw
materials from United States Steel and the primary supplier of rounds for our
tubular facility in Lorain, Ohio. During the first quarter of 2001, United
States Steel discontinued applying the equity method of accounting since
investments in and advances to Republic had been reduced to zero. United States
Steel now accounts for this investment under the cost method. On April 2, 2001,
Republic filed to reorganize under Chapter 11 of the U.S. Bankruptcy Code.
Republic has continued to supply the Lorain mill since filing for bankruptcy.
During the first quarter of 2001, as a result of Republic's action, United
States Steel recorded a pretax charge of $74 million for potentially
uncollectible receivables from Republic and certain debt obligations of $14
million previously assumed by Republic. Due to further financial deterioration
of Republic during the balance of 2001, United States Steel recorded a pretax
charge of $68 million in the fourth quarter of 2001 related to a portion of the
remaining Republic trade receivables and retiree medical cost reimbursements
owed by Republic. At December 31, 2001, United States Steel's remaining
financial exposure to Republic was approximately $19 million. On April 25, 2002,
Republic announced that it had signed a non-binding letter of intent with two
investors to sell substantially all of its assets for approximately $450 million
in cash and assumption of liabilities. Republic further stated that this
transaction is subject to a number of conditions including bankruptcy court
approval. On May 7, 2002, Republic informed the bankruptcy court that one of the
other parties has withdrawn from the letter of intent. The court did not rule on
the sale and set a tentative hearing date for June 17, 2002.

     United States Steel and Kobe Steel, Ltd. ("Kobe") participate in a joint
venture, PRO-TEC, which owns and operates two hot-dip galvanizing lines in
Leipsic, Ohio. The first galvanizing line commenced operations in early 1993. In
November 1998, operations commenced on a second hot-dip galvanized sheet line
which expanded PRO-TEC's capability nearly 400,000 tons a year to 1.0 million
tons annually. Total shipments by PRO-TEC were 909,000 tons in 2001.

     United States Steel and Worthington Industries, Inc. participate in a 50-50
joint venture known as Worthington Specialty Processing which operates a steel
processing facility in Jackson, Michigan. The plant is operated by Worthington
Industries, Inc. The facility contains state-of-the-art technology capable of
processing master steel coils into both slit coils and sheared first operation
blanks including rectangles,

                                       S-16


trapezoids, parallelograms and chevrons. It is designed to meet specifications
for the automotive, appliance, furniture and metal door industries. In 2001,
Worthington Specialty Processing shipments were 241,000 tons.

     United States Steel and Rouge Steel Company ("Rouge") participate in DESCO,
a 50%-owned cost-sharing joint venture which operates an electrogalvanizing
facility located in Dearborn, Michigan. This facility enables United States
Steel to supply the automotive demand for steel with corrosion resistant
properties. The facility can coat both sides of sheet steel with zinc or alloy
coatings and has the capability to coat one side with zinc and the other side
with alloy. Availability of the facility is shared equally by the partners. In
2001, DESCO produced 636,000 tons of electrogalvanized steel. On December 15,
2001, production was halted due to a fire at DESCO. The fire started in the
facility's strip cleaning operation. United States Steel reallocated
substantially all of its portion of DESCO's normal production to other United
States Steel facilities. United States Steel and Rouge plan to return DESCO to
full production by the fourth quarter of 2002.

     United States Steel and Olympic Steel, Inc. participate in a 50-50 joint
venture to process laser-welded sheet steel blanks at a facility in Van Buren,
Michigan. The joint venture conducts business as Olympic Laser Processing.
Laser-welded blanks are used in the automotive industry for an increasing number
of body fabrication applications. United States Steel is the venture's primary
customer and is responsible for marketing the laser-welded blanks. In 2001,
Olympic Laser Processing shipped 1.25 million parts.

     United States Steel, through its wholly owned subsidiary, United States
Steel Export Company de Mexico (44%), along with Feralloy Mexico, S.R.L. de C.V.
(44%), and Intacero de Mexico, S.A. de C.V. (12%), participate in a joint
venture, Acero Prime, which operates a slitting and warehousing facility in San
Luis Potosi, Mexico. In 2001, an expansion project was completed which involved
the construction of a 60,000 square-foot addition that doubled the facility's
size and total warehousing capacity. A second slitting line and an automatic
packaging system were installed as part of the project. Also, a new 70,000
square-foot, in-bond warehouse facility was built in Coahuilla state in Ramos
Arizpe. The warehouse stores and manages coil inventories.

     United States Steel's purchases of transportation services from Transtar
and its subsidiaries, prior to the March 23, 2001 reorganization, and
semi-finished steel from equity investees, primarily Republic, totaled $261
million, $566 million and $361 million in 2001, 2000 and 1999, respectively. At
December 31, 2001 and 2000, United States Steel's payables to these investees
totaled $31 million and $66 million, respectively. United States Steel's
revenues for steel and raw material sales to equity investees, primarily PRO-TEC
and USS-POSCO, totaled $852 million, $958 million and $831 million in 2001, 2000
and 1999, respectively. At December 31, 2001 and 2000, United States Steel's
receivables from these investees were $228 million and $177 million,
respectively. Generally, these transactions were conducted under long-term,
market-based contractual arrangements.

U. S. STEEL KOSICE

     In November 2000, we acquired USSK, headquartered in Kosice in the Slovak
Republic, which owns the steel-making operations and related assets formerly
held by VSZ, a.s., making us the largest flat-rolled producer in Central Europe.
Currently, USSK has annual steel-making capability of 5.0 million net tons and
produces and sells sheet, tin, plate, precision tube and specialty products, as
well as coke. Our strategy is to serve existing United States Steel customers in
Central Europe, grow our customer base in this region, and advance USSK to be a
leading European steel producer and the prime supplier of flat-rolled steel to
the growing Central European market.

     USSK produces steel products in a variety of forms and grades. In 2001,
USSK raw steel production was 4.1 million tons. USSK has three blast furnaces,
two steel shops with two vessels each, a dual strand caster attached to each
steel shop, a hot strip mill, a cold rolling mill, two pickling lines, two
galvanizing lines, a tin coating line, two dynamo lines, a color coating line
and two coke batteries. USSK has recently completed construction and is
beginning the startup of a vacuum degassing facility to increase its capability
to produce steel grades required for high-value applications, and is currently
constructing a continuous annealing line and a second tin coating line to expand
its supply of tin mill products. USSK shipped 3.7 million tons in 2001.
                                       S-17


     In addition, USSK owns 100% of Walzwerk Finow GmbH, located in eastern
Germany, which produces and ships about 90,000 tons per year of welded precision
steel tubes and cold-rolled specialty shaped sections from both cold-rolled and
hot-rolled product supplied primarily by USSK. USSK also has facilities for
manufacturing heating radiators and spiral weld pipe.

     A majority of product sales by USSK are denominated in euros while only a
small percentage of expenditures are in euros. In addition, most interest and
debt payments are in U.S. dollars and the majority of other spending is in U.S.
dollars and Slovak crowns. This results in exposure to currency fluctuations. We
are currently evaluating the evolving currency mix of USSK's cash flows which
may result in a change in the functional currency from U.S. dollars to euros or
Slovak crowns in the future.

     Rannila Kosice, s.r.o., which is 49% owned by USSK and 51% owned by
Rautaruukki Oyj, processes coated sheets, both galvanized and painted, into
various forms which are primarily used in the construction industry. USSK
supplies most of Rannila Kosice's raw materials; however, Rannila Kosice markets
its own finished products.

     United States Steel acquired a 25% interest in VSZ during 2000. VSZ does
not provide its shareholders with financial statements prepared in accordance
with accounting principles generally accepted in the United States ("US GAAP").
Although shares of VSZ are traded on the Bratislava Stock Exchange, those
securities do not have a readily determinable fair value as defined under US
GAAP. Accordingly, United States Steel accounts for its investment in VSZ under
the cost method of accounting.

     On March 8, 2002, USSK announced that it had entered into a conversion and
tolling agreement and a facility management agreement with Sartid, an integrated
steel company with facilities located in Smederevo and Sabac in the Republic of
Serbia. The tolling agreement provides for the conversion of slabs into hot-
rolled bands and cold-rolled full hard into tin-coated products. USSK will
retain ownership of these materials and will market the hot-rolled bands and
finished tin products in its own distribution system. The facility management
agreement permits USSK, or an affiliated company, to have management oversight
of Sartid's tin processing facilities at Sabac. In addition, USSK, the
Government of the Republic of Serbia and Sartid have signed a letter of intent
that provides USSK with the opportunity to explore possibilities for involvement
in the restructuring of Sartid.

EMPLOYEES

     The average number of active United States Steel domestic employees during
2001 was 21,078. The average number of active USSK employees during 2001 was
16,083. Currently, substantially all domestic hourly employees of our steel,
coke and taconite pellet facilities are covered by a collective bargaining
agreement with the USWA which expires in August 2004 and includes a no-strike
provision. Other domestic hourly employees (for example, those engaged in coal
mining and transportation activities) are represented by the United Mine Workers
of America, USWA and other unions. In addition, most employees of USSK are
represented by the union OZ Metalurg under a collective bargaining agreement
expiring March 2004, which is subject to annual wage negotiations.

ENVIRONMENTAL MATTERS

     United States Steel maintains a comprehensive environmental policy overseen
by the Corporate Governance and Public Policy Committee of the United States
Steel Board of Directors. The Environmental Affairs organization has the
responsibility to ensure that United States Steel's operating organizations
maintain environmental compliance systems that are in accordance with applicable
laws and regulations. The Executive Environmental Committee, which is comprised
of officers of United States Steel, is charged with reviewing its overall
performance with various environmental compliance programs. Also, United States
Steel, largely through the American Iron and Steel Institute, continues its
involvement in the development of various air, water, and waste regulations with
federal, state and local governments concerning the implementation of cost
effective pollution reduction strategies.

                                       S-21


     The domestic businesses of United States Steel are subject to numerous
federal, state and local laws and regulations relating to the protection of the
environment. These environmental laws and regulations include the Clean Air Act
("CAA") with respect to air emissions; the Clean Water Act ("CWA") with respect
to water discharges; the Resource Conservation and Recovery Act ("RCRA") with
respect to solid and hazardous waste treatment, storage and disposal; and the
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA")
with respect to releases and remediation of hazardous substances. In addition,
all states where United States Steel operates have similar laws dealing with the
same matters. These laws are constantly evolving and becoming increasingly
stringent. The ultimate impact of complying with existing laws and regulations
is not always clearly known or determinable due in part to the fact that certain
implementing regulations for laws such as RCRA and the CAA have not yet been
promulgated or in certain instances are undergoing revision. These environmental
laws and regulations, particularly the CAA, could result in substantially
increased capital, operating and compliance costs.

     For a discussion of environmental capital expenditures and the cost of
compliance for air, water, solid waste and remediation, see "Management's
Discussion and Analysis of Environmental Matters, Litigation and Contingencies."

     United States Steel 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
been mainly for process changes in order to meet CAA 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
United States Steel's products and services, operating results will be adversely
affected. United States Steel believes that its major domestic integrated steel
competitors are confronted by substantially similar conditions and thus does not
believe that its relative position with regard to such competitors is materially
affected by the impact of environmental laws and regulations. However, the costs
and operating restrictions necessary for compliance with environmental laws and
regulations may have an adverse effect on United States Steel's competitive
position with regard to domestic mini-mills and some foreign steel producers and
producers of materials which compete with steel, which may not be required to
undertake equivalent costs in their operations. In addition, the specific impact
on each competitor may vary depending on a number of factors, including the age
and location of its operating facilities and its production methods. For further
information, see "Management's Discussion and Analysis of Environmental Matters,
Litigation and Contingencies."

     Slovak standards relative to air, water and solid waste pollution are set
by statute and these standards are similar to those in the United States and the
European Union. USSK is in material compliance with these standards. USSK
environmental expenses in 2001 included usage fees, permit fees and/or penalties
totaling approximately $6 million. There are no legal proceedings pending
against USSK involving environmental matters. USSK's capital spending commitment
to the Slovak government includes expenditures sufficient to bring USSK into
compliance with all European Union environmental standards by 2005.

     The 1997 Kyoto Global Climate Change Agreement ("Kyoto Protocol") produced
by the United Nations Convention on Climate Change, if ratified by the U.S.
Senate, would require restrictions on greenhouse gas emissions in the United
States. Options that could be considered by federal regulators to force the
reductions necessary to meet these restrictions could escalate energy costs and
thereby increase steel production costs. Until action is taken by the U.S.
Senate to ratify the Kyoto Protocol or to implement some other program to
address greenhouse gas emissions, it is not possible to estimate the effect this
may have on United States Steel.

Air

     The CAA imposes stringent limits on air emissions through a federally
mandated operating permit program that allows for enhanced civil and criminal
enforcement sanctions. The principal impact of the CAA on United States Steel is
on the coke-making and primary steel-making operations of United States Steel,
as described in this section. The coal mining operations and sales of U. S.
Steel Mining may also be affected.

                                       S-22


     The CAA requires the regulation of hazardous air pollutants and development
and promulgation of Maximum Achievable Control Technology ("MACT") Standards.
The amendment to the Chrome Electroplating MACT to include the chrome process at
Gary is expected sometime in the next couple years. The U.S. Environmental
Protection Agency ("EPA") is also promulgating MACT standards for integrated
iron and steel plants and taconite iron ore processing which are expected to be
finalized in 2002. The impact of these new standards could be significant to
United States Steel, but the cost cannot be reasonably estimated until the rules
are finalized.

     The CAA specifically addressed the regulation and control of coke oven
batteries. The National Emission Standard for Hazardous Air Pollutants for coke
oven batteries was finalized in October 1993, setting forth the MACT standard
and, as an alternative, a Lowest Achievable Emission Rate ("LAER") standard.
Effective January 1998, United States Steel elected to comply with the LAER
standards. United States Steel believes it will be able to meet the current LAER
standards. The LAER standards will be further revised in 2010 and additional
health risk-based standards are expected to be adopted in 2020. EPA is in the
process of developing the Phase II Coke MACT for pushing, quenching and battery
stacks which is scheduled to be finalized in 2002. This MACT will impact United
States Steel, but the cost cannot be reasonably estimated at this time.

     The CAA also mandates the nationwide reduction of emissions of acid rain
precursors (sulfur dioxide and nitrogen oxides) from fossil fuel-fired
electrical utility plants. United States Steel, like all other electricity
consumers, will be impacted by increased electrical energy costs that are
expected as electric utilities seek rate increases to comply with the acid rain
requirements.

     In September 1997, the EPA adopted revisions to the National Ambient Air
Quality Standards for ozone and particulate matter which are significantly more
stringent than prior standards. EPA has issued a Nitrogen Oxide ("NOx") State
Implementation Plan ("SIP") call to require certain states to develop plans to
reduce NOx emissions focusing on large utility and industrial boilers. The
impact of these revised standards could be significant to United States Steel,
but the cost cannot be reasonably estimated until the final revised standards
and the NOx SIP call are issued and, more importantly, the states implement
their SIPs covering their standards.

     In 2001, all of the coal production of U. S. Steel Mining was metallurgical
coal, which is primarily used in coke production. While United States Steel
believes that the new environmental requirements for coke ovens will not have an
immediate effect on U. S. Steel Mining, the requirements may encourage
development of steelmaking processes that reduce the usage of coke. The new
ozone and particulate matter standards could be significant to U. S. Steel
Mining, but the cost is not capable of being reasonably estimated until rules
are proposed or finalized.

Water

     United States Steel maintains the necessary discharge permits as required
under the National Pollutant Discharge Elimination System ("NPDES") program of
the CWA, and it is in compliance with such permits. In 1998, United States Steel
entered into a consent decree with the EPA which resolved alleged violations of
the Clean Water Act NPDES permit at Gary Works and provides for a sediment
remediation project for a section of the Grand Calumet River that runs through
Gary Works. Contemporaneously, United States Steel entered into a consent decree
with the public trustees which resolves potential liability for natural resource
damages on the same section of the Grand Calumet River. In 1999, United States
Steel paid civil penalties of $2.9 million for the alleged water act violations
and $0.5 million in natural resource damages assessment costs. In addition,
United States Steel will pay the public trustees $1 million at the end of the
remediation project for future monitoring costs and United States Steel is
obligated to purchase and restore several parcels of property that have been or
will be conveyed to the trustees. During the negotiations leading up to the
settlement with EPA, capital improvements were made to upgrade plant systems to
comply with the NPDES requirements. The sediment remediation project is an
approved final interim measure under the corrective action program for Gary
Works. As of March 31, 2002, project costs have amounted to $6 million with
another $32.4 million presently projected to complete the project over the next
two years. Estimated

                                       S-23


remediation and monitoring costs for this project have been accrued. In
addition, United States Steel was notified by Indiana Department of
Environmental Protection, acting as lead trustee for state and federal agencies,
that United States Steel is a potentially responsible party ("PRP") along with
15 other companies owning property along the Grand Calumet River and Indiana
Harbor Canal in an assessment of Natural Resources Damages downstream of Gary
Works and at the headwaters lagoon. United States Steel and eight other PRPs
formed a joint defense group which proposed terms for the settlement of this
claim, that have been endorsed by representatives for the trustees and the EPA,
to be included in a consent decree presently being negotiated, which United
States Steel expects will resolve this claim.

Solid Waste

     United States Steel continues to seek methods to minimize the generation of
hazardous wastes in its operations. RCRA establishes standards for the
management of solid and hazardous wastes. Besides affecting current waste
disposal practices, RCRA also addresses the environmental effects of certain
past waste disposal operations, the recycling of wastes and the regulation of
storage tanks. Corrective action under RCRA related to past waste disposal
activities is discussed below under "Remediation."

Remediation

     A significant portion of United States Steel's currently identified
environmental remediation projects relate to the remediation of former and
present operating locations. These projects include the remediation of the Grand
Calumet River (discussed above), and the closure and remediation of permitted
hazardous and non-hazardous waste landfills.

     United States Steel is also involved in a number of remedial actions under
CERCLA, RCRA and other federal and state statutes, and it is possible that
additional matters may come to its attention which may require remediation. For
a discussion of remedial actions related to United States Steel, see
"Management's Discussion and Analysis of Environmental Matters, Litigation and
Contingencies."

PROPERTIES

     United States Steel or its predecessors have owned the vast majority of the
domestic properties at least 30 years with no material adverse claim asserted.
In the case of the real property and buildings of USSK, certified copies of the
property registrations were obtained and examined by local counsel prior to the
acquisition.

     Several steel production facilities are leased. The caster facility at
Fairfield, Alabama is subject to a lease expiring in 2012 with an option to
purchase or to extend the lease. A coke battery at Clairton, Pennsylvania, which
is subleased to the Clairton 1314B Partnership, is subject to a lease through
2004 with an option to purchase. The office space in Pittsburgh, Pennsylvania
used by United States Steel is leased through 2017.

     For property, plant and equipment additions, including capital leases, see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

LEGAL PROCEEDINGS

     United States Steel 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 included below in this discussion. The ultimate resolution
of these contingencies could, individually or in the aggregate, be material to
the financial statements. However, management believes that United States Steel
will remain a viable and competitive enterprise even though it is possible that
these contingencies could be resolved unfavorably.

Asbestos Litigation

     United States Steel is a defendant in a large number of cases in which
approximately 18,000 claimants allege injury resulting from exposure to
asbestos. Nearly all of these cases involve multiple defendants. These
                                       S-24


claims fall into three major groups: (1) claims made under certain federal and
general maritime laws by employees of the Great Lakes Fleet or Intercoastal
Fleet, former operations of United States Steel; (2) claims made by persons who
performed work at United States Steel facilities; and (3) claims made by
industrial workers allegedly exposed to an electrical cable product formerly
manufactured by United States Steel. To date all actions resolved have been
either dismissed or resolved for immaterial amounts. In 2001, United States
Steel disposed of claims from approximately 11,300 claimants with aggregate
total payments of less than $200,000 and approximately 10,000 new claims were
filed. It is not possible to predict with certainty the outcome of these
matters; however, based upon present knowledge, management believes that it is
unlikely that the resolution of the remaining actions will have a material
adverse effect on our financial condition. Among the factors that management
considered in reaching this conclusion are: (1) that United States Steel has
been subject to a total of approximately 32,000 asbestos claims over the last
twelve years that have been administratively dismissed due to the failure of the
claimants to present any medical evidence supporting their claims, (2) that over
the last several years the total number of pending claims has remained steady,
(3) that it has been many years since United States Steel employed maritime
workers or manufactured electrical cable and (4) United States Steel's history
of trial outcomes, settlements and dismissals. This statement of belief is a
forward-looking statement. Predictions as to the outcome of pending litigation
are subject to substantial uncertainties with respect to (among other things)
factual and judicial determinations, and actual results could differ materially
from those expressed in this forward-looking statement.

Inland Steel Patent Litigation

     In July 1991, Inland Steel Company ("Inland") filed an action against
United States Steel and another domestic steel producer alleging defendants had
infringed two of Inland's steel-related patents. Inland sought monetary damages
and an injunction against future infringement. In response to this action,
United States Steel and the other producer challenged the validity of the
patents under United States Patent Office procedures. In this proceeding, the
Patent Office rejected all of Inland's patent claims. Inland appealed the
decision and on September 19, 2001, the Court of Appeals for the Federal Circuit
affirmed the decision of the Patent Office. This decision resolves the matter in
United States Steel's favor.

Environmental Proceedings

     The following is a summary of the proceedings of United States Steel that
were pending or contemplated as of December 31, 2001, under federal and state
environmental laws. Except as described herein, it is not possible to accurately
predict the ultimate outcome of these matters. Claims under CERCLA and related
state acts have been raised with respect to the cleanup of various waste
disposal and other sites. CERCLA is intended to expedite the cleanup of
hazardous substances without regard to fault. PRPs for each site include present
and former owners and operators of, transporters to and generators of the
substances at the site. Liability is strict and can be joint and several.
Because of various factors including the ambiguity of the regulations, the
difficulty of identifying the responsible parties for any particular site, the
complexity of determining the relative liability among them, the uncertainty as
to the most desirable remediation techniques and the amount of damages and
cleanup costs and the time period during which such costs may be incurred, it is
impossible to reasonably estimate United States Steel's ultimate cost of
compliance with CERCLA.

     Projections, provided in the following paragraphs, of spending for and/or
timing of completion of specific projects are forward-looking statements. These
forward-looking statements are based on certain assumptions including, but not
limited to, the factors provided in the preceding paragraph. To the extent that
these assumptions prove to be inaccurate, future spending for, or timing of
completion of environmental projects may differ materially from those stated in
forward-looking statements.

     At December 31, 2001, United States Steel had been identified as a PRP at a
total of nineteen CERCLA sites. Based on currently available information, which
is in many cases preliminary and incomplete, management believes that United
States Steel liability for cleanup and remediation costs in connection with
seven of these sites will be between $100,000 and $1 million per site and eight
will be under $100,000.

                                       S-25


     At the remaining four sites, management expects that United States Steel's
share in the remaining cleanup costs at any single site will not exceed $5
million, although it is not possible to accurately predict the amount of sharing
in any final allocation of such costs. The following is a summary of the status
of these sites:

          1. At the former Duluth Works in Minnesota, United States Steel spent
     a total of approximately $11.4 million for cleanup through 2001. The Duluth
     Works was listed by the Minnesota Pollution Control Agency under the
     Minnesota Environmental Response and Liability Act on its Permanent List of
     Priorities. The EPA has consolidated and included the Duluth Works site
     with the St. Louis River and Interlake sites on the EPA's National
     Priorities List. The Duluth Works cleanup has proceeded since 1989. United
     States Steel is conducting an engineering study of the estuary sediments.
     Depending upon the method and extent of remediation at this site, future
     costs are presently unknown and indeterminable.

          2. The two D'Imperio/Ewan sites in New Jersey are waste disposal sites
     where a former subsidiary allegedly disposed of used paint and solvent
     wastes. United States Steel has entered into a settlement agreement with
     the major PRPs at the sites which fixes United States Steel's share of
     liability at approximately $1.2 million, $624,000 of which has been paid.
     The balance, which is expected to be paid over the next several years, has
     been accrued.

          3. In 1988, United States Steel and three other PRPs agreed to the
     issuance of an administrative order by the EPA to undertake emergency
     removal work at the Municipal & Industrial Disposal Co. site in Elizabeth,
     Pa. The cost of such removal, which has been completed, was approximately
     $4.2 million, of which United States Steel paid $3.4 million. The EPA has
     indicated that further remediation of this site may be required in the
     future, but it has not conducted any assessment or investigation to support
     what remediation would be required. In October 1991, the Pennsylvania
     Department of Environmental Resources ("PaDER") placed the site on the
     Pennsylvania State Superfund list and began a Remedial Investigation ("RI")
     which was issued in 1997. It is not possible to estimate accurately the
     cost of any remediation or the shares in any final allocation formula;
     however, based on presently available information, United States Steel may
     have been responsible for as much as 70% of the waste material deposited at
     the site. On October 10, 1995, the U.S. Department of Justice ("DOJ") filed
     a complaint in the U.S. District Court for Western Pennsylvania against
     United States Steel and other Municipal & Industrial Disposal Co.
     defendants to recover alleged costs incurred at the site. In June 1996,
     United States Steel agreed to pay $245,000 to settle the government's
     claims for costs against it, American Recovery, and Carnegie Natural Gas.
     In 1996, United States Steel filed a cost recovery action against parties
     who did not contribute to the cost of the removal activity at the site.
     United States Steel reached a settlement in principle with all of the
     parties except the site owner. PaDER issued its Final Feasibility Study
     Report for the entire site in August 2001. The report identifies and
     evaluates feasible remedial alternatives and selects three preferred
     alternatives. These alternatives are estimated to cost from $17 million to
     $20 million. Consultants for United States Steel have concluded that a less
     costly alternative should be employed at the site, which is estimated to
     cost $5.5 million. Based on the allocation of the liability that has been
     recognized for the past site cleanup activities, the United States Steel
     share of costs for this remedy would be approximately $3.7 million. United
     States Steel is in the process of negotiating a consent decree with the
     Pennsylvania Department of Environmental Protection ("PADEP", formerly
     PaDER). United States Steel has submitted a conceptual remediation plan,
     which PADEP has approved. United States Steel will be submitting a remedial
     design plan based on the remediation plan. PADEP is also seeking
     reimbursement for approximately $2 million in costs. United States Steel
     could potentially be held responsible for an undetermined share of those
     costs.

     In addition, there are thirteen sites related to United States Steel where
information requests have been received or there are other indications that
United States Steel 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 34 additional sites related to United States Steel where
remediation is being sought under other environmental statutes, both federal and
state, or where private parties are seeking remediation through

                                       S-26


discussions or litigation. Based on currently available information, which is in
many cases preliminary and incomplete, management believes that liability for
cleanup and remediation costs in connection with five of these sites will be
under $100,000 per site, another two sites have potential costs between $100,000
and $1 million per site, and eight sites may involve remediation costs between
$1 million and $5 million. Another three sites, including the Grand Calumet
River remediation at Gary Works, the Peters Creek Lagoon remediation at
Clairton, and the potential claim for investigation, restoration and
compensation of injuries to sediments in the East Branch of the Grand Calumet
River near Gary Works, have or are expected to have costs for remediation,
investigation, restoration or compensation in excess of $5 million. Potential
costs associated with remediation at the remaining sixteen sites are not
presently determinable.

     The following is a discussion of remediation activities at the major
domestic United States Steel facilities:

Gary Works

     In 1998, United States Steel entered into a consent decree with the EPA
which resolved alleged violations of the CWA NPDES permit at Gary Works and
provides for a sediment remediation project for a section of the Grand Calumet
River that runs through Gary Works. Contemporaneously, United States Steel
entered into a consent decree with the public trustees which resolves potential
liability for natural resource damages on the same section of the Grand Calumet
River. United States Steel will pay the public trustees $1 million at the end of
the remediation project for future monitoring costs, and United States Steel is
obligated to purchase and restore several parcels of property that have been or
will be conveyed to the trustees. During the negotiations leading up to the
settlement with the EPA, capital improvements were made to upgrade plant systems
to comply with the NPDES requirements. In 1999, United States Steel paid civil
penalties of $2.9 million for the alleged water act violations and $0.5 million
in natural resource damages assessment costs. In addition, United States Steel
purchased properties which were conveyed to the trustees. The sediment
remediation project is an approved final interim measure under the corrective
action program for Gary Works and is expected to cost approximately $35.2
million over the next five years. Estimated remediation and monitoring costs for
this project have been accrued.

     In October 1996, United States Steel was notified by the Indiana Department
of Environmental Management ("IDEM") acting as lead trustee, that IDEM and the
U.S. Department of the Interior had concluded a preliminary investigation of
potential injuries to natural resources related to releases of hazardous
substances from various municipal and industrial sources along the east branch
of the Grand Calumet River and Indiana Harbor Canal. The public trustees
completed a preassessment screen pursuant to federal regulations and have
determined to perform a Natural Resources Damages Assessment. United States
Steel was identified as a PRP along with fifteen other companies owning property
along the river and harbor canal. United States Steel and eight other PRPs have
formed a joint defense group. In 2000, the trustees concluded their assessment
of sediment injuries, which includes a technical review of environmental
conditions. The PRP joint defense group has proposed terms for the settlement of
this claim which have been endorsed by representatives of the trustees and the
EPA to be included in a consent decree that United States Steel expects to
resolve this claim.

     On October 23, 1998, a final Administrative Order on Consent was issued by
the EPA addressing Corrective Action for Solid Waste Management Units throughout
Gary Works. This order requires United States Steel to perform a RCRA Facility
Investigation ("RFI") and a Corrective Measure Study ("CMS") at Gary Works. The
Current Conditions Report, United States Steel's first deliverable, was
submitted to the EPA in January 1997 and was approved by the EPA in 1998. The
First Phase 1 RFI Work Plan, for facility wide groundwater issues, was approved
and sampling began in 2001. Phase I Sampling and Analysis Plans for the Process
Sewers, Sheet and Tin, East Lake/East End, the West End and the Coke Plant areas
have been submitted to the EPA and are expected to be approved by the EPA in
2002.

     IDEM issued notices of violation ("NOVs") relating to Gary Works in 1994
alleging various violations of air pollution requirements. In early 1996, United
States Steel paid a $6 million penalty and agreed to install additional
pollution control equipment and to implement environmental protection programs
over a

                                       S-27


period of several years. A substantial portion of these programs has been
implemented, with expenditures through 2001 of approximately $101 million. The
cost to complete these programs is presently indeterminable. In 1999, United
States Steel entered into an agreed order with IDEM to resolve outstanding air
issues. United States Steel paid a penalty of $207,400 and installed equipment
at the No. 8 Blast Furnace and the No. 1 BOP to reduce air emissions. In
November 1999, IDEM issued an NOV alleging various air violations at Gary Works.
An agreed order is being negotiated.

Clairton

     In 1987, United States Steel and the PaDER entered into a Consent Order to
resolve an incident in January 1985 involving the alleged unauthorized discharge
of benzene and other organic pollutants from Clairton Works in Clairton, Pa.
That Consent Order required United States Steel to pay a penalty of $50,000 and
a monthly payment of $2,500 for five years. In 1990, United States Steel and the
PaDER reached agreement to amend the Consent Order. Under the amended Order,
United States Steel agreed to remediate the Peters Creek Lagoon (a former coke
plant waste disposal site); to pay a penalty of $300,000; and to pay a monthly
penalty of up to $1,500 each month until the former disposal site is closed.
Remediation costs have amounted to $10.0 million with another $1.1 million
presently estimated to complete the project.

Fairless Works

     In January 1992, United States Steel commenced negotiations with the EPA
regarding the terms of an Administrative Order on consent, pursuant to the RCRA,
under which United States Steel would perform a RFI and a CMS at Fairless Works.
A Phase I RFI report was submitted during the third quarter of 1997. A Phase
II/III RFI will be submitted following EPA approval of the Phase I report. The
RFI/CMS will determine whether there is a need for, and the scope of, any
remedial activities at Fairless Works.

Fairfield Works

     In December 1995, United States Steel reached an agreement in principle
with the EPA and the DOJ with respect to alleged RCRA violations at Fairfield
Works. A consent decree was signed by United States Steel, the EPA and the DOJ
and filed with the court on December 11, 1997, under which United States Steel
will pay a civil penalty of $1 million, implement two SEPs costing a total of
$1.75 million and implement a RCRA corrective action at the facility. One SEP
was completed during 1998 at a cost of $250,000. The second SEP is under way. As
of February 22, 2000, the Alabama Department of Environmental Management assumed
primary responsibility for regulation and oversight of the RCRA corrective
action program at Fairfield Works, with the approval of the EPA. The first RFI
work plan for the site was submitted for agency approval in the first quarter of
2001.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  FOR THE THREE YEARS ENDED DECEMBER 31, 2001

     On December 31, 2001, in a tax-free transaction, Marathon Oil Corporation
("Marathon"), formerly USX Corporation, converted each share of its USX-U. S.
Steel Group class of common stock ("Steel Stock") into the right to receive one
share of United States Steel Corporation common stock ("Separation"). The net
assets of United States Steel on December 31, 2001 were approximately the same
as the net assets attributable to Steel Stock at the time of the Separation,
except for a value transfer of $900 million in the form of additional net debt
and other financings retained by Marathon. During the last six months of 2001,
United States Steel completed a number of financings so that, upon the
Separation, the net debt and other financings of United States Steel on a
stand-alone basis were approximately equal to the net debt and other financings
attributable to the Steel Stock less the value transfer and the tax settlement
with Marathon. For a description of the Separation, see "Business."

     United States Steel's Domestic Steel segment is engaged in the production,
sale and transportation of steel mill products, coke, taconite pellets and coal;
the management of mineral resources; real estate development; and engineering
and consulting services. The U. S. Steel Kosice ("USSK") segment, primarily
located in the Slovak Republic, produces and sells steel mill products and coke
mainly for the Central European market. Certain business activities are
conducted through joint ventures and partially owned companies, such as
USS-POSCO Industries LLC ("USS-POSCO"), PRO-TEC Coating Company ("PRO-TEC"),
Clairton 1314B Partnership L.P. and Rannila Kosice, s.r.o. Management's
Discussion and Analysis should be read in conjunction with United States Steel's
Financial Statements and Notes to Financial Statements.

     On March 1, 2001, United States Steel completed the purchase of the tin
mill products business of LTV Corporation ("LTV"), which is now operated as East
Chicago Tin. In this noncash transaction, United States Steel assumed
approximately $66 million of employee related obligations from LTV. The
acquisition was accounted for using the purchase method of accounting. Results
of operations for the year 2001 include the operations of East Chicago Tin from
the date of acquisition. In the fourth quarter of 2001, United States Steel
recorded an intangible asset impairment of $20 million, related to the five-year
agreement for LTV to supply United States Steel with pickled hot bands entered
into in conjunction with the acquisition of LTV's tin mill products business.
This impairment was recorded because LTV permanently ceased operations at their
plants during the quarter pursuant to a bankruptcy court order.

     On March 23, 2001, Transtar, Inc. ("Transtar") completed a reorganization
with its two voting shareholders, United States Steel and Transtar Holdings,
L.P. ("Holdings"), an affiliate of Blackstone Capital Partners L.P. As a result
of this transaction, United States Steel became sole owner of Transtar and
certain of its subsidiaries, including several rail and barge operations.
Holdings became owner of the other subsidiaries of Transtar. Because the
reorganization involved the sale of certain subsidiaries to Holdings, a
noncontrolling shareholder, Transtar recorded a gain by comparing the carrying
value of the businesses sold to their fair value. United States Steel's share of
the gain recognized by Transtar was $68 million, which is included in income
(loss) from investees. Concurrently, United States Steel accounted for the
change in ownership of Transtar using the step-acquisition purchase method of
accounting. Also, in connection with this transaction, United States Steel
recognized a favorable deferred tax adjustment of $33 million related to its
investment in the stock of Transtar that was no longer required when United
States Steel acquired 100% of Transtar. United States Steel previously accounted
for its investment in Transtar under the equity method of accounting. Transtar
provides rail and barge transportation services to a number of United States
Steel's facilities as well as other customers in the steel, chemicals and forest
products industries.

     Certain sections of Management's Discussion and Analysis include
forward-looking statements concerning trends or events potentially affecting the
businesses of United States Steel. These statements typically contain words such
as "anticipates," "believes," "estimates," "expects" or similar words indicating
that future outcomes are not known with certainty and are subject to risk
factors that could cause these outcomes to differ significantly from those
projected. In accordance with "safe harbor" provisions of the

                                       S-29


Private Securities Litigation Reform Act of 1995, these statements are
accompanied by cautionary language identifying important factors, though not
necessarily all such factors, that could cause future outcomes to differ
materially from those set forth in forward-looking statements. For additional
risk factors affecting the businesses of United States Steel, see "Risk Factors"
beginning on page 2 of the Prospectus.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

     Management's discussion and analysis of its financial condition and results
of operations are based upon United States Steel's financial statements, which
have been prepared in accordance with accounting standards generally accepted in
the United States of America. The preparation of these financial statements
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at year-end, and the reported amount of revenues and expenses during
the year. Management regularly evaluates these estimates, including those
related to the carrying value of property, plant and equipment, valuation
allowances for receivables, inventories and deferred income tax assets;
liabilities for deferred income taxes, potential tax deficiencies, environmental
obligations, potential litigation claims and settlements; and assets and
obligations related to employee benefits. Management estimates are based on
historical experience and various other assumptions that are believed to be
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Accordingly, actual results may differ
materially from current expectations under different assumptions or conditions.

     Management believes that the following critical accounting policies affect
the more significant judgments and estimates used in the preparation of the
financial statements.

     Depreciation -- United States Steel records depreciation primarily using a
modified straight-line method based upon estimated lives of assets and
production levels. The modification factors for domestic steel producing assets
range from a minimum of 85% at a production level below 81% of capability, to a
maximum of 105% for a 100% production level. No modification is made at the 95%
production level, considered the normal long-range level. Depreciation charges
for 2001, 2000 and 1999 were 85%, 94% and 99%, respectively, of straight-line
depreciation based on production levels for each of the years. For certain
equipment related to railroad operations, depreciation is recorded on the
straight-line method, utilizing a composite or grouped approach, based on
estimated lives of assets.

     Asset Impairments -- United States Steel evaluates the impairment of its
property, plant and equipment on an individual asset basis or by logical
groupings of assets. Asset impairments are recognized when the carrying value of
those productive assets exceed their aggregate projected undiscounted cash
flows. If future demand and market conditions are less favorable than those
projected by management, additional asset write-downs may be required.

     Allowances for Doubtful Accounts -- United States Steel maintains
allowances for doubtful accounts for estimated losses resulting from the
inability of customers to make required payments. If the financial condition of
our customers were to deteriorate, resulting in an impairment of their ability
to make payments, additional allowances may be required.

     Inventories -- United States Steel determines the cost of inventories
primarily under the last-in, first-out ("LIFO") method. Consequently, the
overall carrying value of inventories is significantly less than the replacement
cost. United States Steel writes down inventories for the difference between the
carrying value of the inventories and the estimated market value on a worldwide
basis. If actual market conditions are less favorable than those projected by
management, additional write-downs may be required.

     Deferred Taxes -- United States Steel records a valuation allowance to
reduce deferred tax assets to the amount that is more likely than not to be
realized. While United States Steel has considered future taxable income and
ongoing prudent and feasible tax planning strategies in assessing the need for
the valuation allowance, in the event that United States Steel were to determine
that it would be able to realize deferred tax assets in the future in excess of
the net recorded amount, an adjustment to the deferred tax assets would increase
income in the period such determination was made. Likewise, should United States
Steel determine

                                       S-30


that it would not be able to realize all or part of its deferred tax assets in
the future, an adjustment to the valuation allowance for deferred tax assets
would be charged to income in the period such determination was made.

     United States Steel makes no provision for deferred U.S. income taxes on
the undistributed earnings of USSK and other consolidated foreign subsidiaries
because management intends to permanently reinvest such earnings in foreign
operations. If circumstances change and it is determined that earnings will be
remitted in the foreseeable future, a charge would be required to record the
U.S. deferred tax liability for the amounts planned to be remitted.

     Liabilities for Potential Tax Deficiencies -- United States Steel records
liabilities for potential tax deficiencies. These liabilities are based on
management's judgment of the risk of loss should those items be challenged by
taxing authorities. In the event that United States Steel were to determine that
tax-related items would not be considered deficiencies or that items previously
not considered to be potential deficiencies could be considered as potential tax
deficiencies (as a result of an audit, tax ruling or other positions or
authority) an adjustment to the liability would be recorded through income in
the period such determination was made.

     Environmental Remediation -- United States Steel provides for remediation
costs and penalties when the responsibility to remediate is probable and the
amount of associated costs is reasonably determinable. Remediation liabilities
are accrued based on estimates of known environmental exposures and are
discounted in certain instances. United States Steel regularly monitors the
progress of environmental remediation. Should studies indicate that the cost of
remediation is to be more than previously estimated, an additional accrual would
be recorded in the period in which such determination was made.

     Accruals for Potential Litigation Claims and Settlements -- United States
Steel records accruals for potential litigation claims and settlements when
legal counsel advises that an obligation is probable and reasonably estimable.
Changes in findings and negotiations as the cases progress cause changes in the
recorded accruals.

     Pensions and Other Postretirement Benefits ("OPEB") -- Net pension and OPEB
expense recorded for pension and other postretirement benefits are based on,
among other things, assumptions of the discount rate, estimated return on plan
assets, salary increases, the mortality of participants and the current level
and escalation of health care costs in the future. Changes in these and other
factors and differences between actual and assumed changes in the present value
of liabilities or assets of United States Steel's plans above certain thresholds
could cause net annual expense to increase or decrease materially from year to
year.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF INCOME

     Due to the capital intensive nature of integrated steel production, the
principal drivers of United States Steel's financial results are price, volume
and mix. To the extent that these factors are affected by industry conditions
and the overall economic climate, revenues and income will reflect such
conditions.

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

(a) Includes revenue from the sale of steel production by-products, real estate
    development, resource management, and engineering and consulting services
    and, beginning in 2001, transportation services.

     Total revenues and other income increased by $243 million in 2001 from 2000
primarily due to the inclusion of USSK revenues for the full year, the inclusion
of Transtar revenues following the reorganization and higher income from
investees relating to the gain on the Transtar reorganization, partially offset
by lower domestic shipment volumes (domestic steel shipments decreased 955,000
tons) and lower average domestic steel product prices (average prices decreased
$23 per ton). Total revenues and other income in 2000 increased by $662 million
from 1999 primarily due to the consolidation of Lorain Tubular effective January
1, 2000, higher average realized prices, particularly tubular product prices,
and lower losses from investees, which, in 1999, included a $47 million charge
for the impairment of United States Steel's investment in USS/Kobe Steel Company
("USS/Kobe").

(a) Certain amounts have been removed from segment income and appear in items
    not allocated to segments for consistency with the 2001 presentation method.

    principally attributable to former business units of United States Steel.

(c) In excess of facility repair costs.

SEGMENT INCOME (LOSS) FOR DOMESTIC STEEL

     Domestic Steel operations recorded a segment loss of $461 million in 2001
versus segment income of $98 million in 2000, a decrease of $559 million. The
decrease in segment income was primarily due to lower prices, primarily for
sheet products, lower domestic shipment volumes which resulted in less efficient
operating rates and higher unit costs, lower income from coke and taconite
pellet operations, lower results from tin operations during the phase out of
operations at Fairless and higher than anticipated start-up and operating
expenses associated with the March acquisition of East Chicago Tin, and business
interruption effects at USS-POSCO following the cold mill fire in May, some of
which were offset by insurance recoveries already received in the second half of
2001. Offsetting these decreases were improved results from coal operations due
to improved operating and geological conditions as well as higher tubular prices
during the first half of 2001.

     Segment income for Domestic Steel operations in 2000 decreased $17 million
from 1999. The decrease in segment income for Domestic Steel was primarily due
to lower throughput, lower income from raw materials operations, particularly
coal operations, and lower sheet shipments resulting from high levels of
imports.

                                       S-33


SEGMENT INCOME FOR U. S. STEEL KOSICE

     USSK segment income for the full-year 2001 was $123 million compared to $2
million in 2000 for the period following United States Steel's acquisition of
USSK on November 24, 2000. The increase is primarily due to United States
Steel's full year of ownership, changes in commercial strategy, strong customer
focused marketing and a favorable cost structure.

ITEMS NOT ALLOCATED TO SEGMENTS:

     NET PERIODIC PENSION CREDITS, which are primarily noncash, totaled $120
million in 2001, $273 million in 2000 and $234 million in 1999. The decrease of
$153 million in the net periodic pension credit from 2000 to 2001 was primarily
due to the $69 million effect of the transition asset being fully amortized in
2000 and an unfavorable change in the amortization of actuarial (gains)/losses.
The increase of $39 million from 1999 to 2000 was primarily due to a favorable
change in the amortization of actuarial (gains)/losses. Net periodic pension
credits in 2001 and 1999 include settlement and termination effects.

     GAIN ON TRANSTAR REORGANIZATION represents United States Steel's share of
the gain in 2001. Because this was a transaction with a noncontrolling
shareholder, Transtar, Inc. recognized a gain by comparing the carrying value of
the businesses sold to their fair value.

     INSURANCE RECOVERIES RELATED TO USS-POSCO FIRE represent United States
Steel's share of insurance recoveries in excess of facility repair costs for the
cold-rolling mill fire at USS-POSCO in 2001.

     ASSET IMPAIRMENTS -- TRADE RECEIVABLES were for charges related to
receivables exposure from financially distressed steel companies, primarily
Republic Technologies International, LLC ("Republic"), in 2000 and 2001.

     ASSET IMPAIRMENTS -- OTHER RECEIVABLES were for charges related to retiree
medical cost reimbursements owed by Republic in 2001.

     In 2000, IMPAIRMENT AND OTHER COSTS RELATED TO INVESTMENTS IN EQUITY
INVESTEES totaled $36 million to establish reserves against notes from Republic
and to represent United States Steel's share of Republic special charges which
resulted from the completion of a financial restructuring of Republic. In 1999,
impairment and other costs related to investments in equity investees totaled
$54 million related to the impairment of United States Steel's investment in
USS/Kobe, costs related to the formation of Republic and other non-recurring
equity investee charges.

     Income from operations in 1999 also included a LOSS ON INVESTMENT USED TO
SATISFY INDEXED DEBT OBLIGATIONS of $22 million from the termination of
ownership in RTI International Metals, Inc. ("RTI").

     COSTS RELATED TO FAIRLESS SHUTDOWN resulted from the permanent shutdown of
the cold rolling and tin mill facilities at Fairless Works in 2001.

     COSTS RELATED TO THE SEPARATION were for United States Steel's share of
professional fees and expenses and certain other costs directly attributable to
the Separation in 2001.

     ASSET IMPAIRMENTS -- INTANGIBLE ASSET was for the impairment of an
intangible asset in 2001 related to the five-year agreement for LTV to supply
United States Steel with pickled hot bands entered into in conjunction with the
acquisition of LTV's tin mill products business.

     ASSET IMPAIRMENTS -- COAL was for asset impairments at coal mines in
Alabama and West Virginia in 2000 following a reassessment of long-term
prospects after adverse geological conditions were encountered.

     ENVIRONMENTAL AND LEGAL CONTINGENCIES relate to certain environmental and
legal accruals in 2000 and 1999.

     The VOLUNTARY EARLY RETIREMENT PROGRAM PENSION SETTLEMENT in 1999 relates
to a favorable pension settlement primarily related to salaried employees.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES increased by $315 million in
2001 as compared to 2000. The increase was due to several factors, including the
$153 million decrease in the net periodic pension credit previously discussed.
Other contributing factors were the increase in costs in 2001 as a result of the
USSK acquisition and the reorganization of Transtar, Separation costs and the
impairment of retiree medical cost reimbursements owed by Republic. The increase
in selling, general and administrative expenses of $60 million from 1999 to 2000
was primarily due to a $42 million decrease in the portion of the net periodic
pension credit recorded in selling, general and administrative expenses, as well
as increased costs following the acquisition of USSK.

     NET INTEREST AND OTHER FINANCIAL COSTS for each of the last three years are

(a) In December 1996, USX issued $117 million of 6 3/4% Exchangeable Notes Due
    February 1, 2000 ("Indexed Debt") indexed to the price of RTI common stock.
    The carrying value of Indexed Debt was adjusted quarterly to settlement
    value, based on changes in the value of RTI common stock. Any resulting
    adjustment was credited to income and included in interest and other
    financial costs.

     Adjusted net interest and other financial costs increased by $103 million
in 2001 as compared with 2000. This increase was largely due to higher average
debt levels, which resulted from negative cash flow and the elective funding for
employee benefits and the acquisition of USSK, both of which occurred in the
fourth quarter of 2000. Adjusted net interest and other financial costs
increased $18 million in 2000 as compared with 1999, primarily due to higher
average debt levels.

     The CREDIT FOR INCOME TAXES in 2001 was $328 million primarily as a result
of higher losses from operations. The credit included a $33 million deferred tax
benefit associated with the Transtar reorganization. In addition, as a result of
Slovak Republic laws regarding tax credits and certain tax planning strategies
to permanently reinvest earnings in foreign operations, virtually no income tax
provision is recorded for USSK income. If circumstances change and it is
determined that earnings will be remitted in the foreseeable future, a charge
would be required to record the U.S. deferred tax liability for the amounts
planned to be remitted. The provision for income taxes in 2000 decreased $5
million compared to 1999 primarily due to a decline in income from operations,
partially offset by higher state income taxes as certain previously recorded
state tax benefits will not be utilized.

     The EXTRAORDINARY LOSS on extinguishment of debt of $7 million, net of
income tax benefit, in 1999 included a $5 million loss resulting from the
satisfaction of the indexed debt and a $2 million loss for United States Steel's
share of Republic's extraordinary loss related to the early extinguishment of
debt.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF OPERATIONS

     The year 2001 turned out to be an extremely difficult one for the domestic
steel industry. Steel imports to the United States accounted for an estimated
24%, 27% and 26% of the domestic steel market for 2001, 2000 and 1999,
respectively. In 2001, imports of steel pipe increased 9% and imports of hot
rolled sheets decreased 59%, compared to 2000.

     Injurious levels of imports continued to disrupt an already weakened market
in which domestic steel consumption plummeted from an annualized rate of 119
million tons in the first half to 98 million tons in the fourth quarter. The 3%
average growth in the domestic economy predicted by economists never

                                       S-35


materialized -- largely due to a worldwide economic recession in the second half
and the impact of the September 11 tragedies. Contributing to the decline in net
income was a decrease in average realized domestic prices of 5% compared to the
2000 average and higher unit costs due to depressed production levels at all of
our domestic plants.

     Total shipments from the Domestic Steel segment were 9.8 million tons in
2001, 10.8 million tons in 2000 and 10.6 million tons in 1999, and comprised
approximately 9.9% of the domestic steel market in 2001. Domestic Steel
shipments in 2001 were affected by a weak domestic economy, which reduced demand
for sheet, plate and tubular products. Shipments in 1999 were reduced because of
weak tubular markets. High import levels impacted all three years. Exports
accounted for approximately 5% of our shipments from Domestic Steel in 2001, 5%
in 2000 and 3% in 1999.

     USSK shipments were 3.7 million net tons in 2001 and 0.3 million net tons
in 2000 in the short period following the acquisition.

     Domestic raw steel production was 10.1 million tons in 2001, compared with
11.4 million tons in 2000 and 12.0 million tons in 1999. Domestic raw steel
production averaged 79% of capability in 2001, compared with 89% of capability
in 2000 and 94% of capability in 1999. In 2001, domestic raw steel production
was negatively impacted by poor economic conditions and the high level of
imports. In 2000, domestic raw steel production was negatively impacted by a
planned reline at the Gary Works No. 4 blast furnace in July 2000. Because of
market conditions, United States Steel limited its domestic production by
keeping the Gary Works No. 4 blast furnace out of service until February 2001.
Because of market conditions, United States Steel curtailed its domestic
production by keeping the Gary Works No. 6 blast furnace out of service until
February 1999, after a scheduled reline was completed in mid-August 1998. United
States Steel's stated annual domestic raw steel production capability was 12.8
million tons in 2001, 2000 and 1999.

     USSK raw steel production was 4.1 million tons in 2001, or 81% of USSK's
stated annual raw steel production capability of 5.0 million net tons.

     On November 13, 2000, United States Steel joined with eight other producers
and the Independent Steelworkers Union to file trade cases against hot-rolled
carbon steel flat products from 11 countries (Argentina, India, Indonesia,
Kazakhstan, the Netherlands, the People's Republic of China, Romania, South
Africa, Taiwan, Thailand and Ukraine). Three days later, the USWA also entered
the cases as a petitioner. Antidumping ("AD") cases were filed against all the
countries and countervailing duty ("CVD") cases were filed against Argentina,
India, Indonesia, South Africa, and Thailand. The U.S. Department of Commerce
("Commerce") has found margins in all of the cases. The International Trade
Commission ("ITC") had previously found material injury to the domestic industry
in the cases against Argentina and South Africa, and, on November 2, 2001, the
ITC found material injury to the domestic industry in the cases against the
remaining countries.

     On September 28, 2001, United States Steel joined with seven other
producers to file trade cases against cold-rolled carbon steel flat products
from 20 countries (Argentina, Australia, Belgium, Brazil, China, France,
Germany, India, Japan, Korea, Netherlands, New Zealand, Russia, South Africa,
Spain, Sweden, Taiwan, Thailand, Turkey, and Venezuela). AD cases were filed
against all the countries and CVD cases were filed against Argentina, Brazil,
France, and Korea. On November 13, 2001, the ITC determined that there is a
reasonable indication that the U.S. industry is materially injured or threatened
with material injury by reason of the imports in question. These cases will be
the subject of continuing investigations at both Commerce and the ITC.

     United States Steel believes that the remedies provided by AD and CVD cases
are insufficient to correct the widespread dumping and subsidy abuses that
currently characterize steel imports into our country and has, therefore, urged
the U.S. government to take actions such as those in President Bush's three-part
program to address the excessive imports of steel that have been depressing
markets in the United States. United States Steel, nevertheless, intends to file
additional AD and CVD petitions against unfairly traded imports that adversely
impact, or threaten to adversely impact, the results of United States Steel.

                                       S-36


     On March 5, 2002, President Bush announced his decision in response to the
prior finding of the ITC under Section 201 that imports were a substantial cause
of serious injury to the domestic steel industry. Slab imports will be subject
to a quota of 5.4 million tons in the first year on product shipped from
countries other than Canada and Mexico, with excess imports subject to a tariff
of 30%. The annual quota increases to 5.9 million tons in the second year and
6.4 million tons in the third year. Imports of finished carbon and alloy steel
products (hot-rolled, cold-rolled and coated sheet, as well as plate and tin
mill products) from developed countries will be subject to a 30% tariff in the
first year, decreasing to 24% and 18% in the second and third years,
respectively. Imports of these finished products from developing countries will
be subject to an anti-surge mechanism to ensure they do not substantially
increase their shipments from historic levels. Imports of finished flat-rolled
products from Canada and Mexico are not subject to the import remedies announced
by the President. The tariffs and quotas were effective as of March 20, 2002. An
import licensing program applicable to imports covered by the above remedies is
being implemented. The application of the remedies is subject to various
specific product exclusions. The People's Republic of China has filed a
challenge to President Bush's action with the World Trade Organization and other
nations have indicated that they also intend to do so or to take other actions
responding to the Section 201 remedies.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION, CASH FLOWS AND
LIQUIDITY

     CURRENT ASSETS at year-end 2001 decreased $644 million from year-end 2000
primarily due to the settlement in 2001 of the $364 million income tax
receivable from Marathon established in 2000, decreased trade receivables
including receivables subject to a security interest, and a decrease in cash and
cash equivalents. The proceeds from the settlement of the income tax receivable
from Marathon were used to reduce debt attributed to United States Steel.

     INVESTMENTS AND LONG-TERM RECEIVABLES decreased $93 million from year-end
2000 primarily due to the reorganization of Transtar in March of 2001, which
converted an equity method investee into a consolidated subsidiary.

     NET PROPERTY, PLANT AND EQUIPMENT at year-end 2001 increased $345 million
from year-end 2000 primarily due to the Transtar reorganization and the
acquisition of East Chicago Tin, which were noncash transactions.

     CURRENT LIABILITIES at year-end 2001 decreased $132 million from year-end
2000 primarily due to a decrease in accounts payable and long-term debt due
within one year, partially offset by an increase in accrued taxes and amounts
payable to Marathon in connection with the Separation.

     TOTAL LONG-TERM DEBT AND NOTES PAYABLE at December 31, 2001 was $1,434
million, $802 million lower than year-end 2000. The decrease in debt was
primarily due to the $900 million value transfer from Marathon and the receipt
of $819 million of favorable tax settlements with Marathon; partially offset by
negative operating cash flow of $150 million absent the Marathon tax
settlements, net cash used in investing activities of $239 million, debt
repayments of $370 million and dividends paid of $57 million.

     EMPLOYEE BENEFIT LIABILITIES at December 31, 2001 increased $241 million
from year-end 2000 of which $152 million reflected mergers of liabilities
associated with the Transtar reorganization, the acquisition of LTV tin mill
properties and medical expenses of former Lorain Works retirees paid by United
States Steel which are pending collection under Republic bankruptcy proceedings.
The remainder of the increase was primarily due to ongoing accruals in excess of
cash payments from company assets. Following the elective $500 million Voluntary
Employee Benefit Association ("VEBA") funding in the fourth quarter of 2000,
which decreased the employee benefits liability, most union retiree medical
claims are being paid from the VEBA instead of company assets.

     PREFERRED STOCK OF SUBSIDIARY AND MANDATORILY REDEEMABLE CONVERTIBLE
PREFERRED SECURITIES OF A SUBSIDIARY TRUST HOLDING SOLELY JUNIOR SUBORDINATED
CONVERTIBLE DEBENTURES decreased $66 million and $183 million, respectively,
from year-end 2000 in connection with the Separation. These amounts were
previously attributed to United States Steel under the Marathon capital
structure.

                                       S-37


     NET CASH PROVIDED FROM OPERATING ACTIVITIES of $669 million increased in
2001 compared to 2000. The increase was primarily due to the receipt of
favorable intergroup tax settlements from Marathon totaling $819 million in the
2001 period compared to a favorable intergroup settlement of $91 million in the
2000 period and the absence of a $530 million elective contribution to a VEBA
and non-union retiree life insurance trust. The $819 million tax settlement is
reflected in net cash provided by operating activities primarily as favorable
working capital changes of $364 million related to the settlement of the income
tax receivable established in 2000 arising from tax attributes primarily
generated in the year 2000; increases in net income of $426 million for tax
benefits generated by United States Steel in 2001; and net increases in all
other items net of $15 million for state tax benefits generated in 2000. The
last two items were included in the $441 million settlement with Marathon, which
occurred in 2001 as a result of the Separation. Absent these intergroup tax
settlements in 2001 and 2000 and the $530 million of elective contributions in
2000 to a VEBA and non-union retiree life insurance trust, net cash used in
operating activities decreased by $38 million. Cash payments of employee benefit
liabilities were lower because $152 million was paid from assets held in trust
for the plan in 2001 compared to $41 million in 2000 primarily as a result of
approximately $112 million of funds from the VEBA being used to pay retiree
medical and life insurance benefits for union retirees in 2001. In addition,
working capital improved. These improvements were partially offset by decreased
net income.

     Net cash used in operating activities in 2000 was $627 million and
reflected the $500 million elective contribution to a VEBA, a $30 million
elective contribution to a non-union retiree life insurance trust and an income
tax receivable from Marathon of $364 million. These unfavorable effects were
partially offset by a $91 million income tax settlement with Marathon received
in 2000 primarily for the year 1999 in accordance with the group tax allocation
policy. The $500 million VEBA contribution has provided United States Steel with
the flexibility to pay ongoing costs of providing USWA retiree health care and
life insurance benefits from the VEBA instead of from corporate cash flow.

     Net cash used in operating activities was $80 million in 1999 including a
net payment of $320 million under a terminated accounts receivable program.
Excluding the non-recurring VEBA contributions and the accounts receivable
facility termination as well as the tax settlements with Marathon in both years,
net cash provided from operating activities decreased $430 million in 2000 due
mainly to decreased profitability and an increase in working capital.

     CAPITAL EXPENDITURES of $287 million in 2001 included exercising a buyout
option of a lease for half of the Gary Works No. 2 Slab Caster; repairs to the
No. 3 blast furnace at the Mon Valley Works; work on the No. 2 stove at the No.
6 blast furnace at Gary Works; the completion of the replacement coke battery
thruwalls at Gary Works; the completion of an upgrade to the Mon Valley Works
cold reduction mill; systems development projects; and projects at USSK,
including the tin mill expansion and the vacuum degasser project.

     Capital expenditures of $244 million in 2000 included exercising an early
buyout option of a lease for half of the Gary Works No. 2 Slab Caster; the
continued replacement of coke battery thruwalls at Gary Works; installation of
the remaining two coilers at the Gary Works hot strip mill; a blast furnace
stove replacement at Gary Works; and the continuation of an upgrade to the Mon
Valley Works cold reduction mill.

     Capital expenditures of $287 million in 1999 included the completion of the
64" pickle line at Mon Valley Works; the replacement of one coiler at the Gary
Works hot strip mill; an upgrade to the Mon Valley Works cold reduction mill;
replacement of coke battery thruwalls at Gary Works; several projects at Gary
Works allowing for production of specialized high-strength steels, primarily for
the automotive market; and completion of the conversion of the Fairfield Works
pipemill to use rounds instead of square blooms.

     Contract commitments for capital expenditures at year-end 2001 were $84
million, compared with $206 million at year-end 2000. USSK has a commitment to
the Slovak government to spend $700 million for a capital improvements program
at USSK, subject to certain conditions, over a period commencing with the
acquisition date and ending on December 31, 2010. As of December 31, 2001, USSK
had spent $66 million on this capital improvement program.

                                       S-38


     The ACQUISITION OF U. S. STEEL KOSICE S.R.O., consisted of cash payments of
$14 million in 2001 and net cash payments of $10 million in 2000, which
reflected $69 million of cash payments in 2000 less $59 million of cash acquired
in the transaction. Two additional payments of $37.5 million each are to be made
to VSZ in 2002 and 2003 related to the purchase. The first quarter 2001
acquisition of East Chicago Tin and reorganization of Transtar were noncash
transactions.

     INVESTEES -- RETURN OF CAPITAL in 2001 of $13 million reflected a return of
capital on an investment in stock of VSZ in which United States Steel holds a
25% interest.

     NET CHANGE IN ATTRIBUTED PORTION OF MARATHON CONSOLIDATED DEBT AND OTHER
FINANCINGS was a decrease of $74 million in 2001 compared to an increase of
$1,208 million and $147 million in 2000 and 1999, respectively. The decrease in
2001 primarily reflected the net effects of cash provided from operating
activities less cash used for investing activities and dividend payments. The
increase in 2000 primarily reflected the net effects of cash used in operating
activities, including a VEBA contribution, cash used in investing activities,
dividend payments and preferred stock repurchases. The increase in 1999
primarily reflected the net effects of cash used in operating and investing
activities and dividend payments.

     DIVIDENDS PAID decreased $40 million from year 2000 due to a decrease in
the quarterly dividend rate from $0.25 to $0.10 per share paid to USX-U. S.
Steel Group common stockholders, effective with the June 2001 payment. After the
Separation, United States Steel established an initial quarterly dividend rate
of $0.05 per share effective with the March 2002 payment.

Debt Ratings

     As of December 31, 2001, Moody's Investors Service, Inc. assigned a
corporate credit rating of Ba3 to United States Steel with negative
implications. On January 17, 2002, Standard & Poor's Rating Services Corp.
placed the BB corporate credit rating for United States Steel on credit watch
with negative implications. Additionally, Moody's and Standard & Poor's have
assigned Ba3 and BB, respectively, to United States Steel's senior unsecured
debt.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF ENVIRONMENTAL MATTERS, LITIGATION AND
CONTINGENCIES

     United States Steel 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
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 United States Steel's products and services, operating results will be
adversely affected. United States Steel 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 its operating facilities, production
processes and the specific products and services it provides. To the extent that
competitors are not required to undertake equivalent costs in their operations,
the competitive position of United States Steel could be adversely affected.

     USSK is subject to the laws of the Slovak Republic. The environmental laws
of the Slovak Republic generally follow the requirements of the European Union,
which are comparable to domestic standards. USSK has also entered into an
agreement with the Slovak government to bring, over time, its facilities into
European Union environmental compliance.

     In addition, United States Steel expects to incur capital and operating
expenditures to meet environmental standards under the Slovak Republic's
environmental laws for its USSK operation.

(a) Based on previously established U.S. Department of Commerce survey
    guidelines.

(b) These amounts include spending charged against remediation reserves, net of
    recoveries where permissible, but do not include noncash provisions recorded
    for environmental remediation.

     United States Steel's environmental capital expenditures accounted for 5%,
7% and 11% of total capital expenditures in 2001, 2000 and 1999, respectively.

     Compliance expenditures represented 3% of United States Steel's total costs
and expenses in 2001 and 4% of United States Steel's total costs and expenses in
2000 and 1999. Remediation spending during 1999 to 2001 was mainly related to
remediation activities at former and present operating locations. These projects
include remediation of contaminated sediments in a river that receives
discharges from the Gary Works and the closure of permitted hazardous and
non-hazardous waste landfills.

     The Resource Conservation and Recovery Act ("RCRA") establishes standards
for the management of solid and hazardous wastes. Besides affecting current
waste disposal practices, RCRA also addresses the environmental effects of
certain past waste disposal operations, the recycling of wastes and the
regulation of storage tanks.

     United States Steel is in the study phase of RCRA corrective action
programs at its Fairless Works and its former Geneva Works. A RCRA corrective
action program has been initiated at its Gary Works and its Fairfield Works.
Until the studies are completed at these facilities, United States Steel is
unable to estimate the total cost of remediation activities that will be
required.

     United States Steel has been notified that it is a potentially responsible
party ("PRP") at nineteen waste sites under the Comprehensive Environmental
Response, Compensation and Liability Act ("CERCLA") as of December 31, 2001. In
addition, there are thirteen sites related to United States Steel where it has
received information requests or other indications that it 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 34 additional sites related to United States Steel 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, United States Steel is one of a number of parties
involved and the total cost of remediation, as well as United States Steel's
share thereof, is frequently dependent upon the outcome of investigations and
remedial studies. United States Steel accrues for environmental remediation
activities when the responsibility to remediate is probable and the amount of

                                       S-42


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.

     In October 1996, United States Steel was notified by the Indiana Department
of Environmental Management ("IDEM"), acting as lead trustee, that IDEM and the
U.S. Department of the Interior had concluded a preliminary investigation of
potential injuries to natural resources related to releases of hazardous
substances from various municipal and industrial sources along the east branch
of the Grand Calumet River and Indiana Harbor Canal. The public trustees
completed a pre-assessment screen pursuant to federal regulations and have
determined to perform a Natural Resource Damages Assessment. United States Steel
was identified as a PRP along with fifteen other companies owning property along
the river and harbor canal. United States Steel and eight other PRPs have formed
a joint defense group. The trustees notified the public of their plan for
assessment and later adopted the plan. In 2000, the trustees concluded their
assessment of sediment injuries, which includes a technical review of
environmental conditions. The PRP joint defense group has proposed terms for the
settlement of this claim, which have been endorsed by representatives of the
trustees and the U.S. Environmental Protection Agency ("EPA") to be included in
a consent decree that United States Steel expects will resolve this claim.

     In 1998, United States Steel entered into a consent decree with the EPA
which resolved alleged violations of the Clean Water Act National Pollution
Discharge Elimination System ("NPDES") permit at Gary Works and provides for a
sediment remediation project for a section of the Grand Calumet River that runs
through Gary Works. Contemporaneously, United States Steel entered into a
consent decree with the public trustees, which resolves potential liability for
natural resource damages on the same section of the Grand Calumet River. In
1999, United States Steel paid civil penalties of $2.9 million for the alleged
water act violations and $0.5 million in natural resource damages assessment
costs. In addition, United States Steel will pay the public trustees $1 million
at the end of the remediation project for future monitoring costs and United
States Steel is obligated to purchase and restore several parcels of property
that have been or will be conveyed to the trustees. During the negotiations
leading up to the settlement with EPA, capital improvements were made to upgrade
plant systems to comply with the NPDES requirements. As of December 31, 2001,
the sediment remediation project is an approved final interim measure under the
corrective action program for Gary Works and is expected to cost approximately
$35.2 million over the next five years. Estimated remediation and monitoring
costs for this project have been accrued.

     At the former Duluth Works in Minnesota, United States Steel spent a total
of approximately $11.4 million through 2001. The Duluth Works was listed by the
Minnesota Pollution Control Agency under the Minnesota Environmental Response
and Liability Act on its Permanent List of Priorities. The EPA has consolidated
and included the Duluth Works site with the other sites on the EPA's National
Priorities List. The Duluth Works cleanup has proceeded since 1989. United
States Steel is conducting an engineering study of the estuary sediments.
Depending upon the method and extent of remediation at this site, future costs
are presently unknown and indeterminable.

     In 1997, USS/Kobe, a joint venture between United States Steel and Kobe
Steel, Ltd. ("Kobe"), was the subject of a multi-media audit by the EPA that
included an air, water and hazardous waste compliance review. USS/Kobe and the
EPA entered into a tolling agreement pending issuance of the final audit and
commenced settlement negotiations in July 1999. In August 1999, the steelmaking
and bar producing operations of USS/Kobe were combined with companies controlled
by Blackstone Capital Partners II to form Republic. The tubular operations of
USS/Kobe were transferred to a newly formed entity, Lorain Tubular Company, LLC
("Lorain Tubular"), which operated as a joint venture between United States
Steel and Kobe until December 31, 1999, when United States Steel purchased all
of Kobe's interest in Lorain Tubular. Republic and United States Steel are
continuing negotiations with the EPA. Most of the matters raised by the EPA
relate to Republic's facilities; however, air discharges from United States
Steel's #3 seamless pipe mill have also been cited. United States Steel will be
responsible for matters relating to its facilities. The final report and
citations from the EPA have not been issued.

                                       S-43


     In 1987, United States Steel and the Pennsylvania Department of
Environmental Resources ("PADER") entered into a Consent Order to resolve an
incident in January 1985 involving the alleged unauthorized discharge of benzene
and other organic pollutants from Clairton Works in Clairton, Pa. That Consent
Order required United States Steel to pay a penalty of $50,000 and a monthly
payment of $2,500 for five years. In 1990, United States Steel and the PADER
reached agreement to amend the Consent Order. Under the amended Order, United
States Steel agreed to remediate the Peters Creek Lagoon (a former coke plant
waste disposal site); to pay a penalty of $300,000; and to pay a monthly penalty
of up to $1,500 each month until the former disposal site is closed. Remediation
costs have amounted to $9.9 million with another $1.1 million presently
projected to complete the project.

     In 1988, United States Steel and three other PRPs agreed to the issuance of
an administrative order by the EPA to undertake emergency removal work at the
Municipal & Industrial Disposal Co. site in Elizabeth Township, Pa. The cost of
such removal, which has been completed, was approximately $4.2 million, of which
United States Steel paid $3.4 million. The EPA indicated that further
remediation of this site would be required. In October 1991, the PADER placed
the site on the Pennsylvania State Superfund list and began a Remedial
Investigation ("RI"), which was issued in 1997. United States Steel's share of
any final allocation formula for cleanup of the entire site was never
determined; however, based on presently available information, United States
Steel may have been responsible for as much as 70% of the waste material
deposited at the site. The Pennsylvania Department of Environmental Protection
("PADEP"), formerly PADER, issued its Final Feasibility Study Report for the
entire site in August 2001. The report identifies and evaluates feasible
remedial alternatives and selects three preferred alternatives. These
alternatives are estimated to cost from $17 million to $20 million. Consultants
for United States Steel have concluded that a less costly alternative should be
employed at the site, which is estimated to cost $5.5 million. Based on the
allocation of liability that has been recognized for past site cleanup
activities, the United States Steel share of costs for this remedy would be
approximately $3.7 million. United States Steel is in the process of negotiating
a consent decree with PADEP. United States Steel has submitted a conceptual
remediation plan, which PADEP has approved. United States Steel will be
submitting a remedial design plan based on the remediation plan. PADEP is also
seeking reimbursement for approximately $2 million in costs. United States Steel
could potentially be held responsible for an undetermined share of those costs.

     In September 2001, United States Steel agreed to an Administrative Order on
Consent with the State of North Carolina for the assessment and cleanup of a
Greensboro, N.C. fertilizer manufacturing site. The site was owned by Armour
Agriculture Chemical Company (now named Viad) from 1912 to 1968. United States
Steel owned the site from 1968 to 1986 and sold the site to LaRoche Industries
in 1986. The agreed order allocated responsibility for assessment and cleanup
costs as follows: Viad -- 48%, United States Steel -- 26% and LaRoche -- 26%;
and LaRoche was appointed to be the lead party responsible for conducting the
cleanup. In March 2001, United States Steel was notified that LaRoche had filed
for protection under the bankruptcy law. On August 23, 2001, the allocation of
responsibility for this site assessment and cleanup and the cost allocation was
approved by the bankruptcy court in the LaRoche bankruptcy. The estimated
remediation costs are $4.4 million to $5.7 million. United States Steel's
estimated share of these costs is $1.6 million.

     New or expanded environmental requirements, which could increase United
States Steel's environmental costs, may arise in the future. United States Steel
intends to comply with all legal requirements regarding the environment, but
since many of them are not fixed or presently determinable (even under existing
legislation) and may be affected by future legislation, it is not possible to
predict accurately the ultimate cost of compliance, including remediation costs
which may be incurred and penalties which may be imposed. However, based on
presently available information, and existing laws and regulations as currently
implemented, United States Steel does not anticipate that environmental
compliance expenditures (including operating and maintenance and remediation)
will materially increase in 2002. United States Steel's environmental capital
expenditures are expected to be approximately $28 million in 2002 primarily
related to projects at Gary Works and at USSK (approximately $8 million).
Predictions beyond 2002 can only be broad-based estimates, which have varied,
and will continue to vary, due to the ongoing evolution of specific regulatory
requirements, the possible imposition of more stringent requirements and the
availability of new

                                       S-44


technologies to remediate sites, among other matters. Based upon currently
identified projects, United States Steel anticipates that environmental capital
expenditures will be approximately $49 million in 2003 including $17 million for
USSK; however, actual expenditures may vary as the number and scope of
environmental projects are revised as a result of improved technology or changes
in regulatory requirements and could increase if additional projects are
identified or additional requirements are imposed.

     United States Steel is a defendant in a large number of cases in which
approximately 18,000 claimants allege injury resulting from exposure to
asbestos. Nearly all of these cases involve multiple defendants. These claims
fall into three major groups: (1) claims made under certain federal and general
maritime laws by employees of the Great Lakes Fleet or Intercoastal Fleet,
former operations of United States Steel; (2) claims made by persons who
performed work at United States Steel facilities; and (3) claims made by
industrial workers allegedly exposed to an electrical cable product formerly
manufactured by United States Steel. To date all actions resolved have been
either dismissed or resolved for immaterial amounts. In 2001, United States
Steel disposed of claims from approximately 11,300 claimants with aggregate
total payments of less than $200,000 and approximately 10,000 new claims were
filed. It is not possible to predict with certainty the outcome of these
matters; however, based upon present knowledge, management believes that it is
unlikely that the resolution of the remaining actions will have a material
adverse effect on our financial condition. Among the factors that management
considered in reaching this conclusion are: (1) that United States Steel has
been subject to a total of approximately 32,000 asbestos claims over the last
twelve years that have been administratively dismissed due to the failure of the
claimants to present any medical evidence supporting their claims, (2) that over
the last several years the total number of pending claims has remained steady,
(3) that it has been many years since United States Steel employed maritime
workers or manufactured electrical cable and (4) United States Steel's history
of trial outcomes, settlements and dismissals. This statement of belief is a
forward-looking statement. Predictions as to the outcome of pending litigation
are subject to substantial uncertainties with respect to (among other things)
factual and judicial determinations, and actual results could differ materially
from those expressed in this forward-looking statement.

     United States Steel 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. The
ultimate resolution of these contingencies could, individually or in the
aggregate, be material to the United States Steel Financial Statements. However,
management believes that United States Steel will remain a viable and
competitive enterprise even though it is possible that these contingencies could
be resolved unfavorably to United States Steel.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Management Opinion Concerning Derivative Instruments

     United States Steel uses commodity-based and foreign currency derivative
instruments to manage its price risk. Management has authorized the use of
futures, forwards, swaps and options to manage exposure to price fluctuations
related to the purchase of natural gas, heating oil and nonferrous metals and
also certain business transactions denominated in foreign currencies. Derivative
instruments used for trading and other activities are marked-to-market and the
resulting gains or losses are recognized in the current period in income from
operations. While United States Steel's risk management activities generally
reduce market risk exposure due to unfavorable commodity price changes for raw
material purchases and products sold, such activities can also encompass
strategies that assume price risk.

     Management believes that the use of derivative instruments, along with risk
assessment procedures and internal controls, does not expose United States Steel
to material risk. The use of derivative instruments could materially affect
United States Steel's results of operations in particular quarterly or annual
periods. However, management believes that use of these instruments will not
have a material adverse effect on financial position or liquidity.

                                       S-45


Commodity Price Risk and Related Risks

     In the normal course of its business, United States Steel is exposed to
market risk or price fluctuations related to the purchase, production or sale of
steel products. To a lesser extent, United States Steel is exposed to price risk
related to the purchase, production or sale of coal and coke and the purchase of
natural gas, steel scrap, iron ore and pellets, and certain nonferrous metals
used as raw materials.

     United States Steel's market risk strategy has generally been to obtain
competitive prices for its products and services and allow operating results to
reflect market price movements dictated by supply and demand. However, United
States Steel uses derivative commodity instruments (primarily over-the-counter
commodity swaps) to manage exposure to fluctuations in the purchase price of
natural gas, heating oil and certain nonferrous metals. The use of these
instruments has not been significant in relation to United States Steel's
overall business activity.

     Sensitivity analyses of the incremental effects on pretax income of
hypothetical 10% and 25% decreases in commodity prices for open derivative
commodity instruments as of December 31, 2001, and December 31, 2000, are

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

(a) With the adoption of SFAS No. 133, the definition of a derivative instrument
    has been expanded to include certain fixed price physical commodity
    contracts. Such instruments are included in the above table. Amounts reflect
    the estimated incremental effect on pretax income of hypothetical 10% and
    25% decreases in closing commodity prices for each open contract position at
    December 31, 2001, and December 31, 2000. Management evaluates the portfolio
    of derivative commodity instruments on an ongoing basis and adjusts
    strategies to reflect anticipated market conditions, changes in risk
    profiles and overall business objectives. Changes to the portfolio
    subsequent to December 31, 2001, may cause future pretax income effects to
    differ from those presented in the table.

     United States Steel uses OTC commodity swaps to manage exposure to market
risk related to the purchase of natural gas, heating oil and certain nonferrous
metals. United States Steel recorded net pretax other than trading activity
losses of $13 million in 2001, gains of $2 million in 2000 and losses of $3
million in 1999. These gains and losses were offset by changes in the realized
prices of the underlying hedged commodities.

Interest Rate Risk

     United States Steel is subject to the effects of interest rate fluctuations
on certain of its non-derivative financial instruments. A sensitivity analysis

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

(a) Fair values of cash and cash equivalents, receivables, notes payable,
    accounts payable and accrued interest approximate carrying value and are
    relatively insensitive to changes in interest rates due to the short-term
    maturity of the instruments. Accordingly, these instruments are excluded
    from the table.

(b) Reflects, by class of financial instrument, the estimated incremental effect
    of a hypothetical 10% decrease in interest rates at December 31, 2001, and
    December 31, 2000, on the fair value of United States Steel's non-derivative
    financial instruments. For financial liabilities, this assumes a 10%
    decrease in the weighted average yield to maturity of United States Steel's
    long-term debt at December 31, 2001, and December 31, 2000.

(c) Includes amounts due within one year.

(d) Fair value was based on market prices where available, or current borrowing
    rates for financings with similar terms and maturities.

     At December 31, 2001, United States Steel's portfolio of long-term debt was
comprised primarily of fixed-rate instruments. Therefore, the fair value of the
portfolio is relatively sensitive to effects of interest rate fluctuations. This
sensitivity is illustrated by the $79 million increase in the fair value of
long-term debt assuming a hypothetical 10% decrease in interest rates. However,
United States Steel's sensitivity to interest rate declines and corresponding
increases in the fair value of its debt portfolio would unfavorably affect
United States Steel's results and cash flows only to the extent that United
States Steel elected to repurchase or otherwise retire all or a portion of its
fixed-rate debt portfolio at prices above carrying value.

Foreign Currency Exchange Rate Risk

     United States Steel is subject to the risk of price fluctuations related to
anticipated revenues and operating costs, firm commitments for capital
expenditures and existing assets or liabilities denominated in currencies other
than U.S. dollars, in particular the euro and Slovak koruna. United States Steel
has not generally used derivative instruments to manage this risk. However,
United States Steel has made limited use of forward currency contracts to manage
exposure to certain currency price fluctuations. At December 31, 2001, United
States Steel had no open forward currency contracts. In November 2001, the month
in which United States Steel had the most foreign currency exchange maturities,
total notional maturities were $19.4 million.

                                       S-47


Equity Price Risk

     United States Steel is subject to equity price risk and market liquidity
risk related to its investment in VSZ, a.s., the former parent of U. S. Steel
Kosice, s.r.o. These risks are not readily quantifiable for several reasons,
including the absence of a readily determinable fair value as determined under
U.S. generally accepted accounting principles.

Safe Harbor

     United States Steel's quantitative and qualitative disclosures about market
risk include forward-looking statements with respect to management's opinion
about risks associated with United States Steel's use of derivative instruments.
These statements are based on certain assumptions with respect to market prices
and industry supply of and demand for steel products and certain raw materials.
To the extent that these assumptions prove to be inaccurate, future outcomes
with respect to United States Steel's hedging programs may differ materially
from those discussed in the forward-looking statements.

OUTLOOK FOR 2002

     For a discussion of our outlook see "Management's Discussion and Analysis
of Financial Condition and Results of Operations for the Three Months Ended
March 31, 2002 -- Outlook."

ACCOUNTING STANDARDS

     Effective January 1, 2001, United States Steel adopted Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS No. 133"), as amended by SFAS Nos. 137 and 138.
This Statement, as amended, requires recognition of all derivatives at fair
value as either assets or liabilities. Changes in fair value will be reflected
in current period net income or other comprehensive income depending on the
designation of the derivative instrument. A cumulative effect adjustment
relating to the adoption of SFAS No. 133 was recognized in other comprehensive
income. The cumulative effect adjustment relates only to deferred gains or
losses for hedge transactions as of December 31, 2000. The effect of adoption of
SFAS No. 133 was less than $1 million, net of tax.

     In June 2001, the Financial Accounting Standards Board ("FASB") issued
Statements of Financial Accounting Standards No. 141, "Business Combinations"
("SFAS No. 141"), No. 142, "Goodwill and Other Intangible Assets" ("SFAS No.
142") and No. 143, "Accounting for Asset Retirement Obligations" ("SFAS No.
143"). The adoption of SFAS No. 141 and SFAS No. 142 on January 1, 2002 did not
have a material impact on the results of operations or financial position of
United States Steel.

     SFAS No. 143 establishes a new accounting model for the recognition and
measurement of retirement obligations associated with tangible long-lived
assets. SFAS No. 143 requires that an asset retirement obligation should be
capitalized as part of the cost of the related long-lived asset and subsequently
allocated to expense using a systematic and rational method. United States Steel
will adopt the Statement effective January 1, 2003. The transition adjustment
resulting from the adoption of SFAS No. 143 will be reported as a cumulative
effect of a change in accounting principle. At this time, United States Steel
has not completed its assessment of the effect of the adoption of this Statement
on either its financial position or results of operations.

     In August 2001, the FASB approved SFAS No. 144, "Accounting for Impairment
or Disposal of Long-Lived Assets" ("SFAS No. 144"). This Statement establishes a
single accounting model for long-lived assets to be disposed of by sale and
provides additional implementation guidance for assets to be held and used and
assets to be disposed of other than by sale. United States Steel adopted SFAS
No. 144 effective January 1, 2002. There was no financial statement implication
related to the adoption of SFAS No. 144, and the guidance will be applied on a
prospective basis.

                                       S-48


                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                   FOR THE THREE MONTHS ENDED MARCH 31, 2002

     Effective with the first quarter of 2002, following the separation from
Marathon Oil Corporation ("Marathon"), formerly USX Corporation (the
"Separation"), United States Steel established a new internal financial
reporting structure, which resulted in a change in reportable segments. In
addition, United States Steel revised the presentation of several items of
income and expense within income (loss) from reportable segments. Net pension
credits, costs related to former businesses and administrative expenses
previously not reported at the segment level are now directly charged or
allocated to the reportable segments and other businesses. Reported results for
the first quarter of 2001 have been conformed to the current year presentation.

     United States Steel now has three reportable operating segments:
Flat-rolled Products ("Flat-rolled"), Tubular Products ("Tubular"), and U. S.
Steel Kosice ("USSK").

     The Flat-rolled segment includes the operating results of United States
Steel's domestic integrated steel mills and equity investees involved in the
production of sheet, plate and tin mill products. These operations are
principally located in the United States and primarily serve customers in the
transportation (including automotive), appliance, service center, converter,
container, industrial, and construction markets.

     The Tubular segment includes the operating results of United States Steel's
domestic tubular production facilities and an equity investee involved in the
production of tubular goods. These operations produce and sell both seamless and
electric resistance weld tubular products and primarily serve customers in the
oil, gas and petrochemicals markets.

     The composition of the USSK segment is unchanged from prior periods and
includes the operating results of United States Steel's integrated steel mill
located in the Slovak Republic, a production facility in Germany, and equity
investees, primarily located in Central Europe. These operations produce and
sell sheet, plate, tin, tubular, precision tube and specialty steel products, as
well as coke. USSK primarily serves customers in the Central European
construction, appliance, transportation (including automotive), service center,
container, and oil, gas and petrochemicals markets.

     All other United States Steel businesses not included in reportable
segments are reflected in Other Businesses. These businesses are involved in the
production and sale of coal, coke and taconite pellets; transportation services;
steel mill products distribution ("Straightline"); the management of mineral
resources; the management and development of real estate; and engineering and
consulting services.

     Certain sections of Management's Discussion and Analysis include
forward-looking statements concerning trends or events potentially affecting the
businesses of United States Steel. These statements typically contain words such
as "anticipates," "believes," "estimates," "expects," "intends" or similar words
indicating that future outcomes are uncertain. In accordance with "safe harbor"
provisions of the Private Securities Litigation Reform Act of 1995, these
statements are accompanied by cautionary language identifying important factors,
though not necessarily all such factors that could cause future outcomes to
differ materially from those set forth in forward-looking statements. For
additional risk factors affecting the businesses of United States Steel, see
Supplementary Data -- Disclosures About Forward-Looking Statements in the United
States Steel Annual Report on Form 10-K for the year ended December 31, 2001.

RESULTS OF OPERATIONS

     REVENUES AND OTHER INCOME decreased by $130 million in the first quarter of
2002 compared with the same period in 2001. The decrease primarily reflected
lower average realized prices for domestic sheet and tubular products; lower
average realized prices for USSK; reduced domestic tubular, plate and coke
shipments; and lower income from investees which, in the first quarter of 2001,
included the gain on the Transtar reorganization. These declines were partially
offset by increased domestic sheet shipments and the absence of the receivables
impairment, which was included in the first quarter of 2001.

SEGMENT LOSS FOR FLAT-ROLLED

     Segment loss for Flat-rolled was $71 million in the first quarter of 2002,
compared with a loss of $136 million in the first quarter of 2001. The decreased
loss is primarily due to lower energy costs, lower costs per ton from improved
operating efficiencies and higher flat-rolled shipments, partially offset by
lower average realized flat-rolled steel prices.

SEGMENT INCOME FOR TUBULAR

     Segment income for Tubular was $2 million in the first quarter of 2002, a
decline of $23 million compared with the first quarter of 2001, primarily due to
lower average tubular shipments and realized prices, and a continuing surge of
imports of these products which are not covered by the recent Section 201
action.

SEGMENT INCOME (LOSS) FOR USSK

     Segment loss for USSK was $1 million in the first quarter of 2002, compared
with income of $41 million in the first quarter of 2001. The change is primarily
due to lower average realized steel prices and delays in restarting operations
following a blast furnace outage in January 2002.

INCOME (LOSS) FOR OTHER BUSINESSES

     Loss for Other Businesses in the first quarter of 2002 was $11 million,
compared with a loss of $27 million in the first quarter of 2001. The
improvement is primarily due to higher income from iron ore operations as a
result of higher shipment levels and lower energy costs.

SPECIAL ITEMS:

     COSTS RELATED TO FAIRLESS SHUTDOWN resulted from the permanent shutdown of
the cold-rolling and tin mill facilities at Fairless Works in the fourth quarter
of 2001.

                                       S-50


     INSURANCE RECOVERIES RELATED TO USS-POSCO FIRE represent United States
Steel's share of insurance recoveries in excess of facility repair costs for the
cold-rolling mill fire at USS-POSCO in 2001.

     REVERSAL OF LITIGATION ACCRUAL represents the reversal in the first quarter
of 2002 of a prior litigation accrual as a result of a final court ruling in
United States Steel's favor.

     GAIN ON TRANSTAR REORGANIZATION represents United States Steel's share of
the gain recognized in the first quarter of 2001.

     ASSET IMPAIRMENTS - RECEIVABLES were for charges in the first quarter of
2001 related to receivables exposure from financially distressed steel
companies, primarily Republic.

     NET INTEREST AND OTHER FINANCIAL COSTS increased $46 million in the first
quarter of 2002 compared with the same period in 2001. Last year's first quarter
included a favorable adjustment to interest of $67 million that was related to
prior years' taxes. Excluding this favorable adjustment, net interest and other
financial costs in the first quarter of 2002 decreased $21 million from the
first quarter of 2001 primarily due to a lower average debt level following the
December 31, 2001 value transfer of $900 million from Marathon.

     The CREDIT FOR INCOME TAXES in the first quarter 2002 was $12 million
compared with $98 million in the first quarter of 2001. The credit for income
taxes in the first quarter of 2002 reflected a tax benefit for pretax losses at
the estimated annual effective tax rate of approximately 13%. As a result of
Slovak Republic laws regarding tax credits and management's intention to
permanently reinvest earnings in foreign operations, virtually no income tax
provision is recorded for USSK income. In the first quarter of 2001, effective
tax rates were applied to United States Steel's domestic and foreign operations
separately. As a result, the credit for income taxes reflected an estimated
annual effective tax rate of approximately 30% for United States Steel's
domestic operations, and virtually no tax provision for USSK income. The tax
credit in the first quarter of 2001 also included a $33 million deferred tax
benefit associated with the Transtar reorganization and an unfavorable
adjustment of $15 million primarily related to the settlement of prior years'
taxes.

     NET INCOME decreased $92 million in the first quarter of 2002, compared to
the same period in 2001, primarily reflecting the factors discussed above.

OPERATING STATISTICS

     Flat-rolled shipments of 2.3 million tons for the first quarter of 2002
increased about 9% from the first quarter 2001 and 15% from the fourth quarter
of 2001. Tubular shipments of 188,000 tons for the first quarter of 2002
decreased about 36% from the same period in 2001 and improved approximately 5%
from the fourth quarter of 2001. At USSK, first quarter 2002 shipments of
756,000 tons were about the same as in the first quarter of 2001 and down
approximately 13% from the fourth quarter of 2001.

     Raw steel capability utilization for domestic facilities and USSK in the
first quarter of 2002 averaged 92.1% and 74.4%, respectively, compared with
83.1% and 77.2% in the first quarter of 2001 and 67.0% and 66.4% in the fourth
quarter of 2001.

BALANCE SHEET

     CASH AND CASH EQUIVALENTS at March 31, 2002 decreased $90 million from
year-end 2001 primarily due to capital expenditures and payment of a $54 million
cash settlement in accordance with the terms of the Separation, partially offset
by cash generated from common stock issued and from operating activities, which
included $200 million from the sale of accounts receivable under the Receivables
Purchase Agreement.

CASH FLOW

     NET CASH PROVIDED FROM OPERATING ACTIVITIES decreased $231 million in the
first quarter of 2002, compared with the first quarter of 2001. The decrease was
due primarily to less favorable working capital changes and a net loss of $83
million in the first quarter of 2002 versus net income of $9 million in the
first quarter of 2001. Working capital changes in the first quarter of 2002 were
an unfavorable $104 million excluding the receipt of $200 million in cash for
the sale of accounts receivable under the Receivables
                                       S-51


Purchase Agreement. This was primarily caused by increased production and sales
levels, particularly in the latter half of the first quarter of 2002, which
resulted in increases in receivables, inventory, and payables. Working capital
changes in the 2001 period included the effects of a favorable income tax
settlement of $364 million with Marathon arising from tax benefits generated by
United States Steel in 2000, partially offset by the unfavorable impact of
accruals in the first quarter of 2001 for income tax benefits relating to 2001.
Working capital changes in 2001 also reflect the impacts of an increase in the
allowance for doubtful accounts due to the impairment of receivables from
Republic.

     CAPITAL EXPENDITURES in the first quarter of 2002 were $56 million,
compared with $37 million in the same period in 2001. The increase was primarily
due to the new quench and temper line project at Lorain Tubular and various
projects at USSK, including the upgrade of the No. 1 Pushing Furnace, the Vacuum
Degassing Facility, and the Sinter Plant Dedusting project.

     Contract commitments for capital expenditures at March 31, 2002, totaled
$90 million, compared with $84 million at December 31, 2001.

     NET CHANGE IN ATTRIBUTED PORTION OF MARATHON CONSOLIDATED DEBT AND OTHER
FINANCIAL OBLIGATIONS reflects a decrease of $226 million in the first quarter
of 2001 in the amount of debt and other financial obligations attributed to
United States Steel by Marathon. Prior to the Separation, debt and certain other
financial obligations that were centrally managed by Marathon were attributed to
United States Steel based on United States Steel's cash flows and capital
structure. The decrease of $226 million was primarily due to United States
Steel's positive cash provided from operations, which included the $364 million
year 2000 tax settlement with Marathon, partially offset by cash used for
capital expenditures and dividend payments.

     SETTLEMENT WITH MARATHON in the first quarter of 2002 reflected a $54
million cash payment made in accordance with the Separation.

     COMMON STOCK ISSUED in the first quarter of 2002 reflects proceeds from
stock purchases made by the United States Steel Corporation Savings Fund Plan
for Salaried Employees and purchases through the Dividend Reinvestment and
Direct Stock Purchase Plan.

     DIVIDENDS PAID in the first quarter of 2002 were $4 million, reflecting the
initial quarterly dividend rate of five cents per share established by United
States Steel after the Separation. Dividends paid in the first quarter of 2001
resulted from a quarterly dividend rate of $0.25 per share paid to USX-U. S.
Steel Group common shareholders and quarterly dividends on the 6.50% Cumulative
Convertible Preferred Stock outstanding in 2001 that was retired by Marathon as
part of the Separation.

LIQUIDITY

     In November 2001, United States Steel entered into a five-year Receivables
Purchase Agreement with financial institutions. United States Steel established
a wholly owned subsidiary, United States Steel Receivables LLC, which is a
special-purpose, bankruptcy-remote entity that acquires, on a daily basis,
eligible trade receivables generated by United States Steel and certain of its
subsidiaries. Fundings under the facility are limited to the lesser of eligible
receivables or $400 million. As of April 30, 2002, United States Steel had $344
million of eligible receivables, of which $240 million were sold, primarily to
fund working capital needs based on increased operating rates.

     In addition, United States Steel entered into a three-year revolving credit
facility expiring December 31, 2004, that provides for borrowings of up to $400
million secured by all domestic inventory and related assets ("Inventory
Facility"), including receivables other than those sold under the Receivables
Purchase Agreement. As of April 30, 2002, $262 million was available to United
States Steel under the Inventory Facility.

     USSK has bank credit facilities aggregating $50 million. At April 30, 2002,
$49 million was available under these facilities.

     United States Steel currently has Senior Notes outstanding in the aggregate
principal amount of $535 million. The Senior Notes impose significant
restrictions on United States Steel such as the following: restrictions on
payments of dividends; limits on additional borrowings, including limiting the
amount of
                                       S-52


borrowings secured by inventories or accounts receivable; limits on
sale/leasebacks; limits on the use of funds from asset sales and sale of the
stock of subsidiaries; and restrictions on our ability to invest in joint
ventures or make certain acquisitions. The Inventory Facility imposes additional
restrictions on United States Steel including the following: effective September
30, 2002, United States Steel must meet an interest expense coverage ratio of at
least 2 to 1 through March 30, 2003 and 2.5 to 1 thereafter and a debt to EBITDA
leverage ratio of no more than 6 to 1 through December 30, 2002, 5.5 to 1
through March 30, 2003, 5 to 1 through June 29, 2003, 4.5 to 1 through September
29, 2003, 4 to 1 through March 30, 2004 and 3.75 to 1 thereafter; limitations on
capital expenditures; and restrictions on investments. If these covenants are
breached or if we fail to make payments under our material debt obligations or
the Receivables Purchase Agreement, creditors would be able to terminate their
commitments to make further loans, declare their outstanding obligations
immediately due and payable and foreclose on any collateral, and it may also
cause termination events to occur under the Receivables Purchase Agreement and a
default under the Senior Notes. Additional indebtedness that United States Steel
may incur in the future may also contain similar covenants, as well as other
restrictive provisions. Cross-default and cross-acceleration clauses in the
Receivables Purchase Agreement, the Inventory Facility, the Senior Notes and any
future additional indebtedness could have an adverse effect upon our financial
position and liquidity.

     United States Steel has utilized surety bonds to provide financial
assurance for certain transactions and business activities. The total amount of
active surety bonds currently being used for financial assurance purposes is
approximately $255 million. Recent events have caused major changes in the
surety bond market including significant increases in surety bond premiums.
These factors, together with our non-investment grade credit rating, have caused
United States Steel to replace some surety bonds with other forms of financial
assurance, and may require it to provide some form of collateral to the surety
bond providers in order to keep bonds in place. The other forms of financial
assurance or collateral could include financial instruments that are supported
by either the Receivables Purchase Agreement or Inventory Facility. The use of
these types of financial instruments for financial assurance and collateral will
have a negative impact on liquidity. During the second quarter of 2002, United
States Steel management expects approximately $100 million of liquidity sources
to be used to provide financial assurance.

     United States Steel is contingently liable for debt and other obligations
of Marathon in the amount of $344 million as of March 31, 2002. Marathon is not
limited by agreement with United States Steel as to the amount of indebtedness
that it may incur. In the event of the bankruptcy of Marathon, these obligations
for which United States Steel is contingently liable, as well as obligations
relating to Industrial Development and Environmental Improvement Bonds and Notes
that were assumed by United States Steel from Marathon, may be declared
immediately due and payable. If that occurs, United States Steel may not be able
to satisfy such obligations. In addition, if Marathon loses its investment grade
ratings, certain of these obligations will be considered indebtedness under the
Senior Notes indenture and for covenant calculations under the Inventory
Facility. This occurrence could prevent United States Steel from incurring
additional indebtedness under the Senior Notes or may cause a default under the
Inventory Facility.

     United States Steel is the sole general partner of and owns a 10% equity
interest in Clairton 1314B Partnership, L.P. As general partner, United States
Steel is responsible for operating and selling coke and by-products from the
partnership's three coke batteries located at United States Steel's Clairton
Works. United States Steel's share of profits and losses is currently 1.75%,
except for United States Steel's share of depreciation and amortization, which
is 45.75%. Beginning in 2003, United States Steel's share of all profits and
losses will increase to 45.75%. The partnership at times has operating cash
shortfalls after payments of distributions to the partners that are funded with
loans from United States Steel. As of March 31, 2002, the partnership owed
United States Steel $6 million, which was repaid in April 2002. United States
Steel may dissolve the partnership under certain circumstances including if it
is required to make equity investments or loans in excess of $150 million to
fund such shortfalls.

     United States Steel management believes that our liquidity will be adequate
to satisfy our obligations for the foreseeable future, including obligations to
complete currently authorized capital spending programs. Future requirements for
United States Steel's business needs, including the funding of capital
expenditures, debt service for outstanding financings, and any amounts that 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,
borrowings and other external financing sources. However, there is no assurance
that our business will generate sufficient operating cash flow or that external
financing sources will be available in an amount sufficient to enable us to
service or refinance our indebtedness or to fund other liquidity needs. If there
is a prolonged delay in the recovery of the manufacturing sector of the U.S.
economy, United States Steel believes that it can maintain adequate liquidity
through a combination of deferral of nonessential capital spending, sales of
non-strategic assets and other cash conservation measures.

     United States Steel management's opinion concerning liquidity and United
States Steel's ability to avail itself in the future of the financing options
mentioned in the above forward-looking statements are based on currently
available information. To the extent that this information proves to be
inaccurate, future availability of financing may be adversely affected. Factors
that could affect the availability of financing include the performance of
United States Steel (as measured by various factors including cash provided from
operating activities), levels of inventories and accounts receivable, the state
of worldwide debt and equity markets, investor perceptions and expectations of
past and future performance, the overall U.S. financial climate, and, in
particular, with respect to borrowings, the levels of United States Steel's
outstanding debt and credit ratings by rating agencies.

ENVIRONMENTAL MATTERS, LITIGATION AND CONTINGENCIES

     United States Steel 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
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 United States Steel's products and services, operating results will be
adversely affected. United States Steel 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 its operating facilities, production
processes and the specific products and services it provides. To the extent that
competitors are not required to undertake equivalent costs in their operations,
the competitive position of United States Steel could be adversely affected.

     USSK is subject to the laws of the Slovak Republic. The environmental laws
of the Slovak Republic generally follow the requirements of the European Union,
which are comparable to domestic standards. USSK has also entered into an
agreement with the Slovak government to bring, over time, its facilities into
European Union environmental compliance.

     In addition, United States Steel expects to incur capital and operating
expenditures to meet environmental standards under the Slovak Republic's
environmental laws for its USSK operation.

     United States Steel has been notified that it is a potentially responsible
party ("PRP") at twenty waste sites under the Comprehensive Environmental
Response, Compensation and Liability Act ("CERCLA") as of

                                       S-54


March 31, 2002. In addition, there are thirteen sites related to United States
Steel where it has received information requests or other indications that it
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 35 additional sites related to United States
Steel 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, United States Steel is one of
a number of parties involved and the total cost of remediation, as well as
United States Steel's share thereof, is frequently dependent upon the outcome of
investigations and remedial studies. United States Steel 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.

     In 1998, United States Steel entered into a consent decree with the EPA
which resolved alleged violations of the Clean Water Act National Pollution
Discharge Elimination System ("NPDES") permit at Gary Works and provides for a
sediment remediation project for a section of the Grand Calumet River that runs
through Gary Works. Contemporaneously, United States Steel entered into a
consent decree with the public trustees, which resolves potential liability for
natural resource damages on the same section of the Grand Calumet River. In
1999, United States Steel paid civil penalties of $2.9 million for the alleged
water act violations and $0.5 million in natural resource damages assessment
costs. In addition, United States Steel will pay the public trustees $1 million
at the end of the remediation project for future monitoring costs and United
States Steel is obligated to purchase and restore several parcels of property
that have been or will be conveyed to the trustees. During the negotiations
leading up to the settlement with EPA, capital improvements were made to upgrade
plant systems to comply with the NPDES requirements. The sediment remediation
project is an approved final interim measure under the corrective action program
for Gary Works. As of March 31, 2002, project costs have amounted to $6 million
with another $32.4 million presently projected to complete the project, over the
next two years. Estimated remediation and monitoring costs for this project have
been accrued. Construction began in January on a Corrective Action Management
Unit ("CAMU") to contain the dredged material on company property north of the
river between Bridge Street and the former American Juice factory. Removal of
PCB-contaminated sediment will start in October at the river's headwaters.

     At Gary Works, United States Steel has agreed to close three hazardous
waste disposal sites located on plant property. The D2 disposal site and a
nearby refuse area will be closed collectively. A CAMU for the West End
Maintenance Area of Gary Works will include wastes from the D5 and T2 disposal
sites. Total costs to close D2, D5, T2 and the refuse area are estimated to be
$18.8 million.

     In 1987, United States Steel and the Pennsylvania Department of
Environmental Resources ("PADER") entered into a Consent Order to resolve an
incident in January 1985 involving the alleged unauthorized discharge of benzene
and other organic pollutants from Clairton Works in Clairton, Pa. That Consent
Order required United States Steel to pay a penalty of $50,000 and a monthly
payment of $2,500 for five years. In 1990, United States Steel and the PADER
reached agreement to amend the Consent Order. Under the amended Order, United
States Steel agreed to remediate the Peters Creek Lagoon (a former coke plant
waste disposal site); to pay a penalty of $300,000; and to pay a monthly penalty
of up to $1,500 each month until the former disposal site is closed. Remediation
costs have amounted to $10.0 million with another $1.1 million presently
estimated to complete the project.

     United States Steel 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. The
ultimate resolution of these contingencies could, individually or in the
aggregate, be material to the United States Steel Financial Statements. However,
management believes that United States Steel will remain a viable and
competitive enterprise even though it is possible that these contingencies could
be resolved unfavorably to United States Steel.

OUTLOOK

     Our domestic order rate began to increase late last year. Sheet facilities
are now fully loaded and spot market price increases are being implemented.
Plate and tubular markets continue to reflect weak demand. In the second quarter
of 2002, domestic shipments are expected to improve and average realized prices
are expected to be higher. For full-year 2002, domestic shipments are expected
to be approximately 10.7 million net tons, including flat-rolled and tubular
shipments of 9.8 million net tons and 0.9 million net tons, respectively.

     USSK's average realized prices in the second quarter 2002 are expected to
improve slightly, with shipments increasing significantly from the first quarter
of 2002. Full year shipments are projected to be approximately 3.8 million net
tons.

     Management is encouraged by improving economic conditions and currently
anticipates that United States Steel will be profitable for 2002.

     For the longer term, domestic shipment levels and realized prices will be
influenced by the strength and timing of a recovery in the manufacturing sector
of the domestic economy, levels of imported steel following the outcome of the
President's Section 201 decision and production capability changes at domestic
facilities. Many factors will determine the strength and timing of such
recovery, and shipment levels and prices are also subject to many of the same
factors. For USSK, economic and political developments in Europe, including many
factors similar to those impacting domestic operations, will impact USSK's
results of operations.

     United States Steel's income from operations includes net pension credits,
which are primarily noncash, associated with all of United States Steel's
pension plans. Net pension credits were $120 million in 2001. At the end of
2000, United States Steel's main pension plan's transition asset was fully
amortized, decreasing the pension credit by $69 million in 2001 and in future
years for this component. In addition, for the year 2002, lower than expected
market returns in the year 2001 and the mergers of Transtar and LTV tin mill
liabilities will further reduce net pension credits to approximately $110
million, excluding settlements and any potential effects of consolidation or
rationalization activities. An unfavorable $8 million settlement charge is
expected in the second quarter of 2002 under the nonqualified pension plan
relative to salaried employees accepting retirement under last year's Voluntary
Early Retirement Program ("VERP"). A settlement effect is not currently expected
under the qualified salaried pension plan in 2002 relative to the VERP program.
The above includes forward-looking statements concerning net pension credits
which can vary depending upon the market performance of plan assets, changes in
actuarial assumptions regarding discount rate and rate of return on plan assets,
plan amendments affecting benefit payout levels and profile changes in the
beneficiary populations being valued. Changes in any of these factors could
cause net pension credits to change. To the extent net pension credits decline
in the future, income from operations would also decline.

     In its retiree medical estimates of escalation, United States Steel
projects an aggregate 8.0% initial trend rate in 2002 that gradually reduces
each year to an ultimate trend rate of 5% in the year 2008. This was increased
from a 7.5% initial trend rate assumed for 2001. The 8.0% rate reflects a
weighting of various escalation rates on different components of the plan, with
some rates as high as 15%, after taking into consideration the demographics of
the affected populations and the different utilization patterns of medicare
versus pre-medicare retirees.

     Capital expenditures for 2002 are expected to be approximately $260
million, including $105 million for USSK. This estimate anticipates entering
into operating leases for certain mobile and systems equipment, valued at
approximately $30 million, the acquisition of which would be included in capital
spending if the leases are not completed. Major expenditures include the
installation of a new quench and temper line at Lorain Tubular; continued
information systems development at Straightline; and projects at USSK, including
continued work on the new tin and continuous annealing lines and the completion
of the vacuum degasser. Over and above this capital spending, $37.5 million will
be paid to VSZ by USSK in both 2002 and 2003 to complete payment for the USSK
acquisition.

     The preceding statement concerning expected 2002 capital expenditures is a
forward-looking statement. This forward-looking statement is based on
assumptions, which can be affected by (among other things)
                                       S-56


levels of cash flow from operations, general economic conditions, business
conditions, availability of capital, whether or not assets are purchased or
financed by operating leases, and unforeseen hazards such as weather conditions,
explosions or fires, which could delay the timing of completion of particular
capital projects. Accordingly, actual results may differ materially from current
expectations in the forward-looking statement.

     United States Steel has publicly stated that it is willing to participate
in consolidation of the domestic steel industry if it would be beneficial to our
shareholders, creditors, customers and employees. A number of important
conditions must occur to facilitate such consolidation including implementation
of President Bush's three-part program to address worldwide overcapacity, relief
from the burden of costs related to retiree obligations of other domestic steel
companies and a new progressive labor agreement. On March 5, 2002, President
Bush announced a Section 201 trade remedy. In addition, United States Steel may
make additional investments in Central Europe to grow our business and to better
serve our customers who are seeking worldwide supply arrangements.

     United States Steel has responded to domestic competition resulting from
excess steel industry capability by eliminating less efficient facilities,
modernizing those that remain and entering into joint ventures, all with the
objective of focusing production on higher value-added products, where superior
quality and special characteristics are of critical importance. Our business
strategy is to maximize our investment in high-end finishing assets and to
minimize or redeploy our investment in domestic raw materials and hot-ends.

     On March 8, 2002, USSK announced that it had entered into a conversion and
tolling agreement and a facility management agreement with Sartid, a.d.
("Sartid"), an integrated steel company with facilities located in Smederevo and
Sabac in the Republic of Serbia. The tolling agreement provides for the
conversion of slabs into hot-rolled bands and cold-rolled full hard into
tin-coated products. USSK will retain ownership of these materials and will
market the hot-rolled bands and finished tin products in its own distribution
system. The facility management agreement permits USSK, or an affiliated
company, to have management oversight of Sartid's tin processing facilities at
Sabac. In addition, USSK, the Government of the Republic of Serbia and Sartid
have signed a letter of intent that provides USSK with the opportunity to
explore possibilities for involvement in the restructuring of Sartid.

     On April 10, 2002, United States Steel announced that it had signed a
letter of intent to sell all of the coal and related assets associated with U.
S. Steel Mining Company's West Virginia and Alabama mines. The sale, which
involves cash consideration and is subject to several contingencies, is expected
to result in a pre-tax gain, excluding the potential recognition of the present
value of obligations related to a multiemployer health care benefit plan created
by the Coal Industry Retiree Health Benefit Act of 1992, which were broadly
estimated to be $76 million at March 31, 2002.

     Republic, an equity investee and major purchaser of raw materials from
United States Steel, as well as a major supplier of rounds for United States
Steel's Lorain Tubular facility, remains in Chapter 11 bankruptcy proceedings.
At March 31, 2002, United States Steel's remaining financial exposure to
Republic was approximately $20 million. On April 25, 2002, Republic announced
that it had signed a non-binding letter of intent with two investors to sell
substantially all of its assets for approximately $450 million in cash and
assumption of liabilities. Republic further stated that this transaction is
subject to a number of conditions including bankruptcy court approval. On May 7,
2002, Republic informed the bankruptcy court that one of the other parties has
withdrawn from the letter of intent. The court did not rule on the sale and set
a tentative hearing date for June 17, 2002.

     The preceding statements concerning anticipated steel demand, steel
pricing, and shipment levels are forward-looking and are based upon assumptions
as to future product prices and mix, and levels of steel production capability,
production and shipments. These forward-looking statements can be affected by
levels of imports following government action on Section 201 activities,
domestic and international economies, domestic production capacity and customer
demand. In the event these assumptions prove to be inaccurate, actual results
may differ significantly from those presently anticipated. The negotiation and
possible consummation of any merger or acquisition agreement and the potential
completion of any industry consolidation or acquisitions, whether domestic or
international, are all subject to numerous conditions, some of which are
described above. Many of these conditions depend upon actions of other parties,
such as the
                                       S-57


federal government, the USWA and foreign governments. There is no assurance that
any merger agreement will be negotiated and/or consummated, or that any industry
domestic or international consolidation in general will occur, nor any
specificity concerning the terms upon which any of these might occur.

     Steel imports to the United States accounted for an estimated 30%, 24% and
27% of the domestic steel market in the first two months of 2002, and for the
years 2001 and 2000, respectively.

     On March 29, 2002, United States Steel joined other major producers of oil
country tubular goods in filing unfair international trade cases against
fourteen countries. Imports of these products have increased more than 390%
during the past two years. Thirteen countries remained subject to the
proceedings following the withdrawal of the anti-dumping petition against
Colombia. On May 10, 2002, the International Trade Commission made a negative
preliminary injury determination. This action causes the investigations at both
the International Trade Commission and the Department of Commerce to be
terminated.

     On April 29, 2002, the U.S. Department of Commerce announced preliminary
determinations in the anti-dumping cases concerning cold-rolled carbon steel
flat products from twenty countries. The Department had previously issued its
preliminary countervailing duty determinations against cold-rolled products from
the four countries that are subject to those proceedings. The U.S. Department of
Commerce and the U.S. International Trade Commission will continue their
investigations in all of the cases.

     The relief in the Section 201 action that was announced by President Bush
on March 5, 2002 became effective for imports entering the U.S. on and after
March 20, 2002. The U.S. Trade Representative will continue to process requests
for exemption from the remedy through July 3, 2002.

ACCOUNTING STANDARDS

     On January 1, 2002, United States Steel adopted Statements of Financial
Accounting Standards ("SFAS") No. 141 "Business Combinations" and No. 142
"Goodwill and Other Intangible Assets." The adoption of these Statements did not
have a material impact on the results of operations or financial position of
United States Steel. SFAS No. 144 "Accounting for Impairment or Disposal of
Long-Lived Assets" was also adopted on January 1, 2002. There was no financial
statement implication related to the adoption of this Statement and the guidance
will be applied on a prospective basis.

     The adoption of these Statements has not affected United States Steel's
critical accounting policies and estimates. For a discussion of critical
accounting policies and estimates, please refer to the Annual Report on Form
10-K for the year ended December 31, 2001.

     In June 2001, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 143 "Accounting for Asset Retirement Obligations." SFAS No. 143 establishes
a new accounting model for the recognition and measurement of retirement
obligations associated with tangible long-lived assets. SFAS No. 143 requires
that an asset retirement obligation should be capitalized as part of the cost of
the related long-lived asset and subsequently allocated to expense using a
systematic and rational method. United States Steel will adopt the Statement
effective January 1, 2003. The transition adjustment resulting from the adoption
of SFAS No. 143 will be reported as a cumulative effect of a change in
accounting principle. At this time, United States Steel has not completed its
assessment of the effect of the adoption of this Statement on either its
financial position or results of operations.

     On April 30, 2002, the FASB issued SFAS No. 145, "Rescission of FASB
Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical
Corrections." Generally, SFAS No. 145 is effective for transactions occurring
after May 15, 2002. There was no financial statement implication related to the
adoption of this Statement. For more information see Note 16 of the Selected
Notes to Financial Statements.

(a) With the adoption of SFAS No. 133, the definition of a derivative instrument
    has been expanded to include certain fixed price physical commodity
    contracts. Such instruments are included in the above table. Amounts reflect
    the estimated incremental effects on pretax income of hypothetical 10% and
    25% decreases in closing commodity prices for each open contract position at
    March 31, 2002. Management evaluates the portfolio of derivative commodity
    instruments on an ongoing basis and adjusts strategies to reflect
    anticipated market conditions, changes in risk profiles and overall business
    objectives. Changes to the portfolio subsequent to March 31, 2002, may cause
    future pretax income effects to differ from those presented in the table.

Interest Rate Risk

     United States Steel is subject to the effects of interest rate fluctuations
on certain of its non-derivative financial instruments. A sensitivity analysis
of the projected incremental effect of a hypothetical 10% decrease in March 31,
2002, interest rates on the fair value of the United States Steel's
non-derivative financial instruments is provided in the following table:



                                                                        INCREMENTAL
                                                                        INCREASE IN
NON-DERIVATIVE                                                 FAIR         FAIR
FINANCIAL INSTRUMENTS(A)                                       VALUE      VALUE(B)
------------------------                                      -------   ------------
                                                              (DOLLARS IN MILLIONS)
                                                                  
Financial assets:
  Investments and long-term receivables.....................  $   43        $--
Financial liabilities:
  Long-term debt (c)(d).....................................  $1,267        $75


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

(a) Fair values of cash and cash equivalents, receivables, notes payable,
    accounts payable and accrued interest approximate carrying value and are
    relatively insensitive to changes in interest rates due to the short-term
    maturity of the instruments. Accordingly, these instruments are excluded
    from the table.

(b) Reflects, by class of financial instrument, the estimated incremental effect
    of a hypothetical 10% decrease in interest rates at March 31, 2002, on the
    fair value of United States Steel's non-derivative financial instruments.
    For financial liabilities, this assumes a 10% decrease in the weighted
    average yield to maturity of United States Steel's long-term debt at March
    31, 2002.

(c) Includes amounts due within one year.

(d) Fair value was based on market prices where available, or current borrowing
    rates for financings with similar terms and maturities.

     At March 31, 2002, United States Steel's portfolio of long-term debt was
comprised primarily of fixed-rate instruments. Therefore, the fair value of the
portfolio is relatively sensitive to effects of interest rate fluctuations. This
sensitivity is illustrated by the $75 million increase in the fair value of
long-term debt assuming a hypothetical 10% decrease in interest rates. However,
United States Steel's sensitivity to interest

                                       S-59


rate declines and corresponding increases in the fair value of its debt
portfolio would unfavorably affect United States Steel's results and cash flows
only to the extent that United States Steel elected to repurchase or otherwise
retire all or a portion of its fixed-rate debt portfolio at prices above
carrying value.

Foreign Currency Exchange Rate Risk

     United States Steel is subject to the risk of price fluctuations related to
anticipated revenues and operating costs, firm commitments for capital
expenditures and existing assets or liabilities denominated in currencies other
than U.S. dollars, in particular the euro and Slovak koruna. United States Steel
has not generally used derivative instruments to manage this risk. However,
United States Steel has made limited use of forward currency contracts to manage
exposure to certain currency price fluctuations. At March 31, 2002, United
States Steel had open euro forward sale contracts for both U.S. dollars (total
carrying value of approximately $27.9 million) and Slovak koruna (total carrying
value of approximately $15.8 million). A 10% increase in the March 31, 2002 euro
forward rates would result in a $4.5 million charge to income.

Equity Price Risk

     As of March 31, 2002, United States Steel was subject to equity price risk
and market liquidity risk related to its investment in VSZ a.s., the former
parent of U. S. Steel Kosice, s.r.o. These risks are not readily quantifiable
for several reasons including the absence of a readily determinable fair value
as determined under U.S. generally accepted accounting principles.

Safe Harbor

     United States Steel's Quantitative and Qualitative Disclosures About Market
Risk include forward-looking statements with respect to management's opinion
about risks associated with United States Steel's use of derivative instruments.
These statements are based on certain assumptions with respect to market prices,
industry supply and demand for steel products and certain raw materials, and
foreign exchange rates. To the extent that these assumptions prove to be
inaccurate, future outcomes with respect to United States Steel's hedging
programs may differ materially from those discussed in the forward-looking
statements.

           CERTAIN UNITED STATES TAX CONSEQUENCES TO NON-U.S. HOLDERS

     The following summary describes the material U.S. federal income and estate
tax consequences of the ownership of common stock by a non-U.S. holder (as
defined below) as of the date hereof.

     This discussion does not address all aspects of U.S. federal income and
estate taxes and does not deal with foreign, state and local consequences that
may be relevant to such non-U.S. holders in light of their personal
circumstances. Special rules may apply to certain non-U.S. holders, such as
certain U.S. expatriates, "controlled foreign corporations," "passive foreign
investment companies," "foreign personal holding companies" and corporations
that accumulate earnings to avoid U.S. federal income tax, that are subject to
special treatment under the Internal Revenue Code of 1986, as amended (the
"Code"). Such entities should consult their own tax advisors to determine the
U.S. federal, state, local and other tax consequences that may be relevant to
them. Furthermore, the discussion below is based upon the provisions of the
Code, and regulations, rulings and judicial decisions thereunder as of the date
hereof, and such authorities may be repealed, revoked or modified so as to
result in U.S. federal income tax consequences different from those discussed
below. PERSONS CONSIDERING THE PURCHASE, OWNERSHIP OR DISPOSITION OF COMMON
STOCK SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE U.S. FEDERAL INCOME
AND ESTATE TAX CONSEQUENCES IN LIGHT OF THEIR PARTICULAR SITUATIONS AS WELL AS
ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY OTHER TAXING JURISDICTION.

     If a partnership holds common stock, the tax treatment of a partner will
generally depend on the status of the partner and the activities of the
partnership. Persons who are partners of partnerships holding common stock
should consult their tax advisors.

     As used herein, a non-U.S. holder of common stock means a holder that is
not:

     - a citizen or resident of the U.S.,

     - a corporation or partnership created or organized in or under the laws of
       the U.S. or any political subdivision thereof,

     - an estate the income of which is subject to U.S. federal income taxation
       regardless of its source, or

     - a trust that (i) is subject to the supervision of a court within the U.S.
       and for which one or more U.S. persons have the ability to control all
       substantial decisions or (ii) has a valid election in effect under
       applicable U.S. Treasury regulations to be treated as a U.S. person.

DIVIDENDS

     Dividends paid to a non-U.S. holder of common stock generally will be
subject to withholding of U.S. federal income tax at a 30% rate or such lower
rate as may be specified by an applicable income tax treaty. However, dividends
that are effectively connected with the conduct of a trade or business by the
non-U.S. holder within the U.S. and, where a tax treaty applies, are
attributable to a U.S. permanent establishment of the non-U.S. holder, are not
subject to the withholding tax, but instead are subject to U.S. federal income
tax on a net income basis at applicable graduated individual or corporate rates.
Certain certification and disclosure requirements must be complied with in order
for effectively connected income to be exempt from withholding. Any such
effectively connected dividends received by a foreign corporation may, under
certain circumstances, be subject to an additional "branch profits tax" at a 30%
rate or such lower rate as may be specified by an applicable income tax treaty.

     A non-U.S. holder of common stock who wishes to claim the benefit of an
applicable treaty rate (and avoid back-up withholding as discussed below) for
dividends, will be required to (a) complete Internal Revenue Service ("IRS")
Form W-8BEN (or successor form) and certify under penalty of perjury that such
holder is not a U.S. person or (b) if common stock is held through certain
foreign intermediaries, satisfy the relevant certification requirements of
applicable Treasury regulations. Special certification and other requirements
apply to certain non-U.S. holders that are entities rather than individuals.

                                       S-61


     A non-U.S. holder of common stock eligible for a reduced rate of U.S.
withholding tax pursuant to an income tax treaty may obtain a refund of any
excess amounts withheld by timely filing an appropriate claim for refund with
the IRS.

GAIN ON DISPOSITION OF COMMON STOCK

     A non-U.S. holder generally will not be subject to U.S. federal income tax
with respect to a gain recognized on a sale or other disposition of common stock
unless

     - the gain is effectively connected with a trade or business of the
       non-U.S. holder in the U.S. and, where a tax treaty applies, is
       attributable to a U.S. permanent establishment of the non-U.S. holder,

     - in the case of a non-U.S. holder who is an individual and holds the
       common stock as a capital asset, such holder is present in the U.S. for
       183 or more days in the taxable year of the sale or other disposition and
       certain other conditions are met, or

     - we are or have been a "U.S. real property holding corporation" for U.S.
       federal income tax purposes.

     An individual non-U.S. holder described in the first bullet point above
will be subject to tax on the net gain derived from the sale under regular
graduated U.S. federal income tax rates. An individual non-U.S. holder described
in the second bullet point above will be subject to a flat 30% tax on the gain
derived from the sale, which may be offset by U.S. source capital losses (even
though the individual is not considered a resident of the U.S.). If a non-U.S.
holder that is a foreign corporation falls under the first bullet point above,
it will be subject to tax on its gain under regular graduated U.S. federal
income tax rates and, in addition, may be subject to the branch profits tax
equal to 30% of its effectively connected earnings and profits or at such lower
rate as may be specified by an applicable income tax treaty. We believe we are
not and do not anticipate becoming a "U.S. real property holding corporation"
for U.S. federal income tax purposes.

FEDERAL ESTATE TAX

     Common stock held by an individual non-U.S. holder at the time of death
will be included in such holder's gross estate for U.S. federal estate tax
purposes, unless an applicable estate tax treaty provides otherwise and,
therefore, may be subject to U.S. federal estate tax.

INFORMATION REPORTING AND BACKUP WITHHOLDING

     We must report annually to the IRS and to each non-U.S. holder the amount
of dividends paid to such holder and the tax withheld with respect to such
dividends, regardless of whether withholding was required. Copies of the
information returns reporting such dividends and withholding may also be made
available to the tax authorities in the country in which the non-U.S. holder
resides under the provisions of an applicable income tax treaty.

     A non-U.S. holder will be subject to backup withholding unless applicable
certification requirements are met.

     Payment of the proceeds of a sale of common stock within the U.S. or
conducted through certain U.S. related financial intermediaries is subject to
both backup withholding and information reporting unless the beneficial owner
certifies under penalties of perjury that it is a non-U.S. holder (and the payor
does not have actual knowledge that the beneficial owner is a U.S. person) or
the holder otherwise establishes an exemption.

     Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules may be allowed as a refund or a credit against such
holder's U.S. federal income tax liability provided the required information is
furnished to the IRS in a timely manner.

     The underwriting agreement provides that the underwriters are obligated to
purchase all the shares of common stock in the offering if any are purchased,
other than those shares covered by the over-allotment option described below.
The underwriting agreement also provides that if an underwriter defaults, the
purchase commitments of non-defaulting underwriters may be increased or the
offering may be terminated.

     We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to 1,425,000 additional shares at the initial public offering
price less the underwriting discounts and commissions. The option may be
exercised only to cover any over-allotments of common stock.

     The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus supplement and to
selling group members at that price less a selling concession of $0.53 per
share. The underwriters and selling group members may allow a discount of $0.10
per share on sales to other broker/dealers. After the initial public offering,
the representatives may change the public offering price and concession and
discount to broker/dealers.

     The following table summarizes the compensation and estimated expenses we
will pay:

     The maximum aggregate discounts and commissions paid to underwriters and
broker/dealers will not exceed 8% of the gross proceeds of the offering.

     We have agreed that we will not offer, sell, contract to sell, pledge or
otherwise dispose of, directly or indirectly, or file with the Securities and
Exchange Commission a registration statement under the Securities Act of 1933,
as amended (the "Securities Act"), relating to, any shares of our common stock
or securities convertible into or exchangeable or exercisable for any shares of
our common stock, or publicly disclose the intention to make any offer, sale,
pledge, disposition or filing, without the prior written consent of the
representatives for a period of 90 days after the date of this prospectus
supplement, except grants of employee stock options pursuant to the terms of a
plan in effect on the date of this prospectus supplement,

                                       S-63


issuances of shares of common stock pursuant to the exercise of options
outstanding on the date of this prospectus supplement or issuances of shares of
common stock pursuant to our dividend reinvestment plan.

     Our executive officers and directors have agreed that they will not offer,
sell, contract to sell, pledge or otherwise dispose of, directly or indirectly,
any shares of our common stock or securities convertible into or exchangeable or
exercisable for any shares of our common stock, enter into a transaction that
would have the same effect, or enter into any swap, hedge or other arrangement
that transfers, in whole or in part, any of the economic consequences of
ownership of our common stock, whether any of these transactions is to be
settled by delivery of our common stock or other securities, in cash or
otherwise, or publicly disclose the intention to make any offer, sale, pledge or
disposition, or to enter into any such transaction, swap, hedge or other
arrangement, without, in each case, the prior written consent of the
representatives for a period of 90 days after the date of this prospectus
supplement.

     We have agreed to indemnify the underwriters against liabilities under the
Securities Act, or contribute to payments that the underwriters may be required
to make in that respect.

     Certain of the underwriters and their respective affiliates have from time
to time performed and may in the future perform various financial advisory,
commercial banking and investment banking services for us and our affiliates,
for which they received or will receive customary fees.

     In connection with the offering, the underwriters may engage in stabilizing
transactions, over-allotment transactions, syndicate covering transactions and
penalty bids in accordance with Regulation M under the Securities Exchange Act
of 1934, as amended (the "Exchange Act").

     - Stabilizing transactions permit bids to purchase the underlying security
       so long as the stabilizing bids do not exceed a specified maximum.

     - Over-allotment involves sales by the underwriters of shares in excess of
       the number of shares the underwriters are obligated to purchase, which
       creates a syndicate short position. The short position may be either a
       covered short position or a naked short position. In a covered short
       position, the number of shares over-allotted by the underwriters is not
       greater than the number of shares that they may purchase in the
       over-allotment option. In a naked short position, the number of shares
       involved is greater than the number of shares in the over-allotment
       option. The underwriters may close out any covered short position by
       either exercising their over-allotment option and/or purchasing shares in
       the open market.

     - Syndicate covering transactions involve purchases of the common stock in
       the open market after the distribution has been completed in order to
       cover syndicate short positions. In determining the source of shares to
       close out the short position, the underwriters will consider, among other
       things, the price of shares available for purchase in the open market as
       compared to the price at which they may purchase shares through the
       over-allotment option. If the underwriters sell more shares than could be
       covered by the over-allotment option, a naked short position, the
       position can only be closed out by buying shares in the open market. A
       naked short position is more likely to be created if the underwriters are
       concerned that there could be downward pressure on the price of the
       shares in the open market after pricing that could adversely affect
       investors who purchase in the offering.

     - Penalty bids permit the representatives to reclaim a selling concession
       from a syndicate member when the common stock originally sold by the
       syndicate member is purchased in a stabilizing or syndicate covering
       transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids
may have the effect of raising or maintaining the market price of our common
stock or preventing or retarding a decline in the market price of the common
stock. As a result, the price of our common stock may be higher than the price
that might otherwise exist in the open market. These transactions may be
effected on the New York Stock Exchange or otherwise and, if commenced, may be
discontinued at any time.

     A prospectus supplement in electronic format may be made available on the
web sites maintained by one or more of the underwriters, or selling group
members, if any, participating in this offering. The
                                       S-64


representatives may agree to allocate a number of shares to underwriters and
selling group members for sale to their online brokerage account holders.
Internet distributions will be allocated by the underwriters and selling group
members that will make internet distributions on the same basis as other
allocations.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

     The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of common stock are made. Any resale of the common stock in Canada must
be made under applicable securities laws which will vary depending on the
relevant jurisdiction, and which may require resales to be made under available
statutory exemptions or under a discretionary exemption granted by the
applicable Canadian securities regulatory authority. Purchasers are advised to
seek legal advice prior to any resale of the common stock.

REPRESENTATIONS OF PURCHASERS

     By purchasing common stock in Canada and accepting a purchase confirmation
a purchaser is representing to us and the dealer from whom the purchase
confirmation is received that

     - the purchaser is entitled under applicable provincial securities laws to
       purchase the common stock without the benefit of a prospectus qualified
       under those securities laws,

     - where required by law, that the purchaser is purchasing as principal and
       not as agent, and

     - the purchaser has reviewed the text above under Resale Restrictions.

RIGHTS OF ACTION -- ONTARIO PURCHASERS ONLY

     Under Ontario securities legislation, a purchaser who purchases a security
offered by this prospectus during the period of distribution will have a
statutory right of action for damages, or while still the owner of the shares,
for rescission against us in the event that this prospectus contains a
misrepresentation. A purchaser will be deemed to have relied on the
misrepresentation. The right of action for damages is exercisable not later than
the earlier of 180 days from the date the purchaser first had knowledge of the
facts giving rise to the cause of action and three years from the date on which
payment is made for the shares. The right of action for rescission is
exercisable not later than 180 days from the date on which payment is made for
the shares. If a purchaser elects to exercise the right of action for
rescission, the purchaser will have no right of action for damages against us.
In no case will the amount recoverable in any action exceed the price at which
the shares were offered to the purchaser and if the purchaser is shown to have
purchased the securities with knowledge of the misrepresentation, we will have
no liability. In the case of an action for damages, we will not be liable for
all or any portion of the damages that are proven to not represent the
depreciation in value of the shares as a result of the misrepresentation relied
upon. These rights are in addition to, and without derogation from, any other
rights or remedies available at law to an Ontario purchaser. The foregoing is a
summary of the rights available to an Ontario purchaser. Ontario purchasers
should refer to the complete text of the relevant statutory provisions.

ENFORCEMENT OF LEGAL RIGHTS

be located outside of Canada and, as a result, it may not be possible for
Canadian purchasers to effect service of process within Canada upon us or those
persons. All or a substantial portion of our assets and the assets of those
persons may be located outside of Canada and, as a result, it may not be
possible to satisfy a judgment against us or those persons in Canada or to
enforce a judgment obtained in Canadian courts against us or those persons
outside of Canada.
