             National Steel Completes Sale of Assets to U.S. Steel


Mishawaka, IN - May 20, 2003 - National Steel Corporation today announced that
it completed the sale of substantially all of its principal steelmaking and
finishing assets and iron ore pellet operations to United States Steel
Corporation for an aggregate purchase price of approximately $1.05 billion,
consisting of approximately $850 million in cash and the assumption of certain
liabilities of approximately $200 million.

         The National Steel assets sold to U.S. Steel in the transaction
include: facilities at National's two integrated steel plants, Great Lakes
Steel, in Ecorse and River Rouge, Michigan, and Granite City Division in
Granite City, Illinois; the Midwest finishing facility in Portage, Indiana;
ProCoil, a steel-processing facility in Canton, Michigan; National Steel
Pellet Company, which produces iron ore pellets; and various other
subsidiaries and joint- venture interests, including National's interest in
Double G Coatings, a hot- dip galvanizing and Galvalume(R) steel facility near
Jackson, Mississippi.

         Mineo Shimura, chairman and chief executive officer of National
Steel, said, "We are very pleased to be able to complete this transaction with
U.S. Steel, which we believe is in the best interests of all National Steel
stakeholders and will assure the delivery of the highest level of service to
our customers, while creating opportunities for our employees and plant
communities. We are actively at work with U.S. Steel to ensure a seamless
transition."

         As previously announced, U.S. Steel reached a new labor agreement
with the United Steelworkers of America covering the USWA-represented plants
of U.S. Steel, including the facilities of National Steel sold to U.S. Steel.

         The transaction is expected to provide National Steel sufficient cash
to satisfy all allowed administrative, priority and secured claims. National
Steel intends to file a Chapter 11 plan of liquidation with the U.S.
Bankruptcy Court for the Northern District of Illinois within 30 days of
closing.
