           United States Steel Announces Filing for Exchange Offer

PITTSBURGH, Oct. 12 /PRNewswire/ -- United States Steel LLC announced today
that it has filed with the Securities and Exchange Commission a Registration
Statement relating to the issuance of up to $365 million of Senior Quarterly
Income Debt Securities due 2031 ("SQUIDS") to be offered in exchange for
outstanding 6.5% Cumulative Convertible Preferred Stock of USX Corporation,
6.75% Convertible Cumulative Quarterly Income Preferred Securities of USX
Capital Trust I and 8.75% Cumulative Monthly Income Preferred Shares, Series A
of USX Capital LLC. The total face amount outstanding of the three securities
is approximately $568 million and if more than $365 million face amount is
tendered, there will be a proration.

         Pending the separation of U.S. Steel and Marathon, the SQUIDS will be
unconditionally guaranteed by USX Corporation. Upon the separation, the USX
guarantee will no longer be applicable and United States Steel will be the
sole obligor of the SQUIDS.

         The Dealer Manager for the exchange offers is Goldman, Sachs & Co.

         The Prospectus that is part of the Registration Statement contains
the following updated Outlook for United States Steel:

         While over the last few months domestic orders for steel had
strengthened and prices had stabilized, our order rate for the fourth quarter
is currently running lower than our third quarter rate. In the third quarter,
Domestic Steel shipments totaled 2.6 million net tons and average realized
prices were lower than the second quarter primarily due to changes in mix,
including decreased sales of tubular and plate products. In the fourth
quarter, we expect Domestic Steel shipments to be approximately 2.3 million
net tons and average realized prices to be about flat compared to the third
quarter. In light of expected slow market conditions in the fourth quarter, we
plan to advance the schedule for a maintenance outage on the Gary Works No. 6
blast furnace.

         On May 31, 2001, a major fire damaged the cold-rolling mill at
USS-POSCO, which is fifty percent owned by United States Steel. Damage was
predominantly limited to the cold-rolling mill area of the plant. USS-POSCO
maintains insurance coverage against such losses, including coverage for
business interruption. The mill is expected to resume production in the first
quarter of 2002, although full production may not be achieved until mid-2002.
Until such time, the plant will continue customer shipments using cold-rolled
coils from United States Steel and POSCO as substitute feedstock.

         For USSK, third quarter shipments totaled approximately 1.0 million
net tons, down slightly from shipments of 1.1 million net tons in the second
quarter, and average realized prices were higher than in the second quarter.
In the fourth quarter, we expect shipments to be slightly lower than in the
third quarter and average realized prices to be comparable to the third
quarter. Based on continued improvement in production performance since
acquisition, USSK raw steel production capability for the second half of 2001
has been increased to 2.5 million net tons, for an annualized rate of 5.0
million net tons.

         For the full year 2001, total shipments are expected to be
approximately 13.5 to 13.8 million net tons with Domestic Steel shipments of
approximately 10 million net tons and USSK shipments of approximately 3.5 to
3.8 million net tons.

         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 and
production capability changes by domestic competitors. Many factors, including
developments flowing from the events of September 11, will determine the
strength and timing of such recovery and the other factors. For USSK, economic
and political developments in Europe and elsewhere will impact USSK's results
of operations in 2002 and thereafter.

         United States Steel owns a 16% equity method investment in Republic
Technologies International, LLC ("Republic") through USX'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 Lorain Tubular. 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
and no supply interruptions are anticipated. United States Steel's carrying
value of this investment in Republic has been reduced to zero. Upon Republic's
filing for bankruptcy, United States Steel accrued a charge for a substantial
portion of the receivables due from Republic. At June 30, 2001, United States
Steel's remaining pre-petition financial exposure to Republic, after recording
various losses and reserves, totaled approximately $30 million.

         The above discussion includes forward-looking statements concerning
shipments, pricing, and equity investee performance. These statements are
based on assumptions as to future product demand, prices and mix, and
production. Steel shipments and prices can be affected by imports and actions
of the U.S. Government and its agencies pertaining to trade, domestic and
international economies, domestic production capacity, and customer demand.
Factors which may affect USSK results are similar to domestic factors,
including excess world supply and foreign currency fluctuations, and also can
be influenced by matters peculiar to international marketing such as tariffs.
In the event these assumptions prove to be inaccurate, actual results may
differ significantly from those presently anticipated.
