       United States Steel Extends and Decreases Minimum Condition to Exchange
                                     Offers

     PITTSBURGH - December 10, 2001.  USX Corporation announced today that its
wholly-owned subsidiary, United States Steel LLC, has decreased the minimum
condition to its exchange offers for certain outstanding equity securities of
USX Corporation and its wholly-owned subsidiaries.  The new minimum condition
requires that at least $25 million aggregate principal amount of United States
Steel LLC's 10% Senior Quarterly Income Debt Securities due 2031 (SQUIDSSM) are
issued in the exchange offers.  In the original minimum condition, the dollar
amount was $150 million.

     Additionally, United States Steel LLC has extended, to 5:00 p.m., New York
City time, on December 14, 2001, the expiration of the exchange offers.  The
exchange offers were originally scheduled to expire at 5:00 p.m., New York City
time, on December 7, 2001.

     In the exchange offers, United States Steel is offering to exchange up to
$365 million aggregate principal amount of SQUIDS for an equal aggregate face
amount of the 6.50% Cumulative Convertible Preferred Stock of USX Corporation
(Preferred Stock), the 6.75% Convertible Quarterly Income Preferred Security of
USX Capital Trust I (QUIPSSM), and the 8.75% Cumulative Monthly Income Series A
Preferred Shares of USX Capital LLC (MIPSr).

     United States Steel LLC has been advised by The Bank of New York, the
exchange agent for the exchange offers, that based on a preliminary count on
December 7th, holders have tendered, including through notices of guaranteed
delivery, $10 million face amount of Preferred Stock, $12 million face amount of
QUIPS, and $26 million face amount of MIPS, representing an aggregate principal
amount of $48 million of SQUIDS issuable pursuant to the exchange offers.

     The exchange offers are being made only through a prospectus dated November
5, 2001, and are being made upon the terms and are subject to the conditions
described in that prospectus.  Beneficial owners of Preferred Stock, QUIPS, or
MIPS who wish to tender in the exchange offers should contact Goldman, Sachs &
Co., the Dealer Manager for the exchange offers, or their own broker, dealer,
trust company, or other financial advisor.

     On December 31, 2001, the then outstanding MIPS will be redeemed, each for
a cash payment of $25 plus accrued but unpaid dividends.  If the separation of
USX Corporation, as described in the prospectus, occurs, the then outstanding
Preferred Stock will be converted, each into the right to receive, in cash, $50
plus accrued but unpaid dividends, and the then outstanding QUIPS will be
redeemed, each for a cash payment of $50 plus accrued but unpaid distributions.
