  U. S. STEEL REACHES TENTATIVE AGREEMENT WITH UNITED STEELWORKERS ON NEW LABOR
  CONTRACT FOR U.S. FLAT-ROLLED, IRON ORE MINING AND SELECT TUBULAR OPERATIONS

     PITTSBURGH, Aug. 12, 2008 - United States Steel Corporation (NYSE: X)
today announced a tentative agreement with the United Steelworkers (USW) on a
new four-year labor contract that will cover approximately 16,000 USW-
represented employees at U. S. Steel's domestic flat-rolled and iron ore mining
facilities as well as tubular operations in Lorain, Ohio, and Fairfield, Ala.
The tentative agreement will replace the contract expiring Sept. 1, 2008, and
remains subject to ratification by the United Steelworkers.
     Commenting on the announcement, U. S. Steel Chairman and Chief Executive
Officer John P. Surma said, "We are pleased to have reached a tentative
agreement with the United Steelworkers on a competitive four-year contract well
in advance of the expiration of our current contract.  We value our ongoing
relationship with the USW and appreciate the contributions that our employees
make to the success of our business.  We believe that this agreement is in the
best interests of our company and all of our stakeholders."
     Details about the tentative agreement will be made available after the

This release contains forward-looking statements with regard to a new labor
agreement.  The new labor agreement is subject to ratification by USW members.
Future profitability and competitiveness are subject to numerous factors, many
of which are beyond the control of U. S. Steel.  In accordance with "safe
harbor" provisions of the Private Securities Litigation Reform Act of 1995,
cautionary statements identifying important factors, but not necessarily all
factors, that could cause actual results to differ materially from those set
forth in the forward-looking statements have been included in the Form 10-K of
U. S. Steel for the year ended December 31, 2007, and in subsequent filings for
