U. S. Steel to Participate in Consortium With LNM Group to Make Tender for Kryvorizhstal

United States Steel Corporation (NYSE: X) confirmed today that it has agreed to make a modest investment for a minority interest in a consortium headed by LNM Group, the world's second largest steel producer, to take part in the tender for the privatisation of Kryviy Rih Mining and Smelting Plant "Kryvorizhstal" ("Kryvorizhstal") in the Republic of Ukraine. Kryvorizhstal owns and operates integrated steelmaking operations, including iron ore mines and coke making operations.

This release contains forward-looking statements with regards to the potential acquisition of Kryvorizhstal by the consortium. Whether such acquisition will be implemented and the timing of such implementation will depend upon a number of factors, many of which are beyond the control of United States Steel Corporation. 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 United States Steel Corporation for the year ended December 31, 2003, and in subsequent filings by United States Steel Corporation.
