-------------------------------------------------------------------------------
            EACH OF THE EXCHANGE OFFERS AND WITHDRAWAL RIGHTS WILL
            EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON DECEMBER 7,
             2001, UNLESS EARLIER TERMINATED OR EXTENDED BY UNITED
                                 STATES STEEL.
-------------------------------------------------------------------------------

         United States Steel LLC, a Delaware limited liability company
("United States Steel"), which is currently a wholly owned subsidiary of USX
Corporation, a Delaware corporation ("USX") is offering, upon the terms and
subject to the conditions set forth in the Prospectus dated November 5, 2001
(the "Prospectus") and the related Letters of Transmittal, to exchange $50
principal amount of SQUIDS for each validly tendered and accepted share of
6.50% Preferred Stock; $50 principal amount of SQUIDS for each validly
tendered and accepted 6.75% QUIPS, plus a cash payment for accrued plus unpaid
distributions; and $25 principal amount of SQUIDS for each validly tendered
and accepted 8.75% MIPS, plus a cash payment for accrued plus unpaid
dividends.

         Holders of shares of 6.50% Preferred Stock tendered and accepted in
the exchange offers will not be paid accrued dividends upon completion of the
exchange offers. Rather, all holders of 6.50% Preferred Stock as of December
3, 2001 will receive payment on December 31, 2001 in the amount of the full
quarterly dividend payable on the 6.50% Preferred Stock for the fourth quarter
of 2001.

         The exchange offers are subject to the conditions described in the
Prospectus, including the minimum condition that at least $150 million
principal amount of SQUIDS, in the aggregate, are issued in the exchange
offers. United States Steel will accept up to a maximum face amount of (i) $77
million of 6.50% Preferred Stock, (ii) $127 million of 6.75% QUIPS and (iii)
$161 million of 8.75% MIPS in the exchange offers. If United States Steel
receives tenders for more than the face amount of any series of Outstanding
Securities than are set forth above, it will prorate the number of validly
tendered Outstanding Securities in such series that it will exchange from each
tendering holder.

         United States Steel is making the exchange offers in connection with
a reorganization of USX, pursuant to which USX will distribute all of the
equity securities of United States Steel Corporation to the holders of USX's
U. S. Steel Group common stock (the "Separation"). Following the Separation,
United States Steel will be an independent, publicly owned company and will no
longer be a subsidiary of USX. As part of the Separation, which is expected to
be completed on or about December 31, 2001, United States Steel LLC will
convert into United States Steel Corporation, a Delaware corporation, and USX
will change its name to Marathon Oil Corporation. The Separation is subject to
the satisfaction or waiver of a number of conditions. The issuance of the
SQUIDS is not subject to completion of the Separation.

         All outstanding 8.75% MIPS will be redeemed on December 31, 2001 for
a cash payment of $25 plus accrued but unpaid dividends. If the Separation
occurs, the then outstanding 6.50% Preferred Stock will be converted into the
right to receive, in cash, $50 per share plus accrued but unpaid dividends and
the then outstanding 6.75% QUIPS will be redeemed for a cash payment of $50
plus accrued but unpaid distributions.

         Until the completion of the Separation, USX will fully and
unconditionally guarantee the SQUIDS. Following the Separation, USX will no
longer guarantee the SQUIDS and the sole obligor of the SQUIDS will be United
States Steel Corporation which, after the Separation, will have a substantial
amount of indebtedness and other obligations and will have a credit rating
below "investment grade," which will be lower than the current credit ratings
of USX.

         The SQUIDS -- The SQUIDS will mature on December 31, 2031. Interest
on the SQUIDS will begin to accrue on the Exchange Date (as defined in the
Prospectus) and will be payable quarterly on each March 31, June 30, September
30 and December 31, commencing March 31, 2002. The SQUIDS will be redeemable
at the option of United States Steel, in whole or in part, on or after
December 31, 2006 at 100% of the principal amount redeemed together with
accrued but unpaid interest to the redemption date. If the USX board of
directors determines not to proceed with the Separation, United States Steel
will have the option to redeem the SQUIDS, in whole or in part, on or prior to
December 31, 2002, at 100% of the principal amount redeemed, together with
accrued but unpaid interest through the redemption date. Ownership of the
SQUIDS will be recorded in book-entry form on the Exchange Date, and will not
be represented by physical certificates.

         Expiration, Extension, Termination and Amendment of the Exchange
Offers -- The exchange offers expire at 5:00 p.m., New York City time, on
December 7, 2001. However, United States Steel may at any time prior to the
expiration date extend the expiration of the exchange offers, terminate the
exchange offers for failure to satisfy any of the conditions to the exchange
offers, or amend the exchange offers by giving oral notice to the Exchange
Agent. Any such extension, termination or amendment will be followed as
promptly as practicable by a public announcement, which, in the case of an
extension, will be made no later than 9:00 a.m., New York City time, on the
next business day after the previously scheduled expiration date.

         Procedures for Tendering Outstanding Securities; ATOP; Withdrawal of
Tenders -- If you wish to tender Outstanding Securities in the exchange
offers, you must tender all Outstanding Securities that you own. Partial
tenders are not permitted. Beneficial owners of Outstanding Securities may
tender by instructing their custodian bank, depositary, broker, trust company
or other nominee to deliver an agent's message or a letter of transmittal to
the Exchange Agent, and to effect a book-entry transfer of the Outstanding
Securities into the account of the Exchange Agent through the Automated Tender
Offer Program of the Depositary Trust Company. Holders of 6.50% Preferred
Stock in certificated form may tender by properly completing and signing the
yellow letter of transmittal, and delivering it, along with the stock
certificate or notice of guaranteed delivery, to the Exchange Agent, or by
delivering the stock certificate to a broker for tendering by book-entry
transfer as set forth above. In all cases, all deliveries necessary to tender
Outstanding Securities must be received by the Exchange Agent prior to the
expiration of the exchange offers, as set forth above. Tenders may be
withdrawn by completing the withdrawal procedures set forth in the Prospectus
prior to the expiration of the exchange offers. Partial withdrawals are not
permitted.

         Exchange Date -- Ownership of SQUIDS issued in the exchange offers
will be recorded in book-entry form on the exchange date, which will be the
third business day following the expiration date of the exchange offers,
unless proration is necessary, in which case the exchange date will be on or
before the seventh business day following the expiration date.

         No Recommendation -- None of United States Steel LLC, USX, the
Exchange Agent, the Information Agent, or the Dealer Managers makes any
recommendation as to whether or not holders of Outstanding Securities should
exchange their securities in the exchange offers.

         Stock Exchange Listing -- The SQUIDS have been approved for listing
on the New York Stock Exchange, subject to official notice of issuance.

         Delivery of Prospectus -- The Prospectus and related documents,
including the Letters of Transmittal, are being delivered to record holders of
Outstanding Securities and, for delivery to beneficial owners, to brokers,
dealers, commercial banks, trust companies and other nominees who are known to
