                                                                   Exhibit 99.1.

USX ANNOUNCES PLAN OF REORGANIZATION

          COLUMBUS, Ohio, April 24 - USX Corporation today announced that its
board of directors authorized management to proceed with the necessary steps to
implement a plan of reorganization of the corporation in order to separate the
energy and steel businesses: USX-Marathon Group (NYSE: MRO) and USX-U. S. Steel
Group  (NYSE: X).
          Thomas J. Usher, chairman and chief executive officer, will inform
shareholders at the firm's 100th annual meeting here that the plan, which is
expected to be implemented at year-end, will create two strong, independent
companies prepared to grow and prosper in each of their rapidly changing
industries.
          The plan envisions a tax-free spin-off of the steel and steel-related
businesses of USX Corporation into a freestanding, publicly traded company to be
known as United States Steel Corporation.  Holders of current USX-U. S. Steel
Group common stock would become holders of United States Steel Corporation
common stock.  Holders of current USX-Marathon Group common stock would become
holders of Marathon Oil Company common stock.  The plan does not contemplate a
cash distribution to shareholders.
          In November 2000, the USX board of directors authorized management to
retain financial, tax and legal advisors to undertake a comprehensive review of
the corporation's capital structure.  In commenting on the plan Usher stated,
"In this regard, Credit Suisse First Boston and Salomon Smith Barney reviewed
many options that would be available to the board in an effort to make Marathon
and U. S. Steel more competitive in their industries and to enhance shareholder
value for holders of both classes of our common stock.  Based in part upon the
advice of the advisors, the board believes that a tax-free spin-off of our steel
business is in the best interest of all of our shareholders."
          Usher explained that separating Marathon and U. S. Steel would give
each company more flexibility in expanding its business through stock-based
acquisitions, which would be highly beneficial in view of the global
consolidation taking place in both the energy and steel industries.  Usher said
that the separation would allow each "new company" to focus its attention and
financial resources on its core business.  It would allow Marathon and
U. S. Steel to each make needed acquisitions based solely on its own business
considerations rather than on business issues related to a combined energy and
steel company.  The separation would give each company independent access to
financial markets and align the liability risks with each business. The USX
board believes that shareholder value for the holders of each of Marathon and
U. S. Steel would be enhanced as a result.
          Usher noted that each new company would carry with it approximately
the same assets and liabilities now associated with its existing business,
except for a value transfer of approximately $900 million from Marathon to U. S.
Steel, intended to maintain U. S. Steel as a strong, independent company.  The
form of the $900 million value transfer would be a reallocation of USX corporate
debt between the current Marathon Group and U. S. Steel Group.  It is planned
that all public debt that remains outstanding will remain with Marathon.  It is
anticipated that both companies would have adequate access to financial markets
with Marathon expected to have an investment grade rating at the current USX
level or higher and U. S. Steel expected to have a slightly below investment
grade rating.  As part of the transaction, transition expenses as well as other
separation costs will be allocated between the two new companies.
          Employees of both U. S. Steel and Marathon and the communities in
which they are located should not be adversely affected by the reorganization
plan.  In addition, retirees from all units will continue to receive pension
benefits from the existing fully funded plans and no changes in any retiree
benefit will result from this reorganization, according to Usher.  Marathon will
continue to be headquartered in Houston, Marathon Ashland Petroleum in Findlay,
Ohio and U. S. Steel in Pittsburgh.
          Under the reorganization plan, Usher will become chairman and chief
executive officer of U. S. Steel. He will become chairman of Marathon Oil
Company and remain chairman of the Marathon Ashland Petroleum LLC board of
managers.  Clarence P. Cazalot, Jr. will become president and chief executive
officer of Marathon Oil Company.  The balance of the management team of each
entity is expected to remain substantially the same as it is today.
          Usher said that the plan of reorganization is subject to the approval
of a majority of the outstanding shares of each class of the current USX common
stock at a special meeting of shareholders, which is expected to be held early
in the fourth quarter of this year.
          He added that the reorganization is subject to several other
conditions, including receipt of a favorable tax ruling from the Internal
Revenue Service (IRS) on the tax-free nature of the transaction, completion of
necessary financing arrangements and receipt of necessary regulatory and third
party consents, and board approval of definitive documentation for the
transaction.  The transaction is expected to occur at year-end, subject to the
absence of any materially adverse change in business conditions for the energy
and/or steel business, delay in obtaining the IRS ruling or other unfavorable
circumstances.
          "We are extremely enthusiastic about this plan and we believe that as
a result, both the energy and steel operations of USX will be well-positioned to
succeed and prosper," Usher said.

USX CORPORATION DECLARES FIRST QUARTER MARATHON DIVIDEND AND REDUCED

U. S. STEEL GROUP DIVIDEND

        PITTSBURGH, April 24, 2001 - USX Corporation announced that the Board

of Directors declared dividends of 23 cents per share on USX-Marathon Group

(NYSE:MRO) Common Stock and 10 cents per share on USX-U. S. Steel Group

(NYSE:X) Common Stock, a decrease of 15 cents per share.  The dividends are in

each case payable June 9, 2001, to stockholders of record at the close of

business May 16, 2001.  The directors also declared a dividend of $0.8125 per

share on USX Corporation's 6.50% Cumulative Convertible Preferred Stock.  This

dividend is payable June 29, 2001 to stockholders of record at the close of

business May 31, 2001.

        Commenting on the U. S. Steel Group dividend reduction, USX

Corporation Board Chairman Thomas J. Usher said, "The Board makes dividend

decisions after considering, among other things, the long-term earnings and

cash flow capabilities of the U. S. Steel Group as well as the dividend

policies of similar publicly traded steel companies."

        Usher continued, "It is clear from a cash flow perspective that we

have not earned the prior dividend for the past two years.  The combination of

the steel import crisis, depressed industry conditions and the uncertain

domestic economy makes a dividend reduction prudent at this time."
