As previously disclosed, on March 6, 2002 National Steel Corporation (the
"Company") and forty-one of its domestic subsidiaries (collectively "the
Debtors") filed voluntary petitions for relief under Chapter 11 of Title 11 of
the United States Code in the United States Bankruptcy Court for the Northern
District of Illinois, Eastern Division (the "Court"). The case was assigned to
the Hon. John H. Squires and is being jointly administered under case number
02-08699. The Debtors remain in possession of their assets and properties, and
continue to operate their businesses and manage their properties as
debtors-in-possession pursuant to sections 1107(a) and 1108 of the Bankruptcy
Code.

On July 25, 2002, the Debtors filed with the Court their required combined
monthly operating report for the month ended June 30, 2002 (the "Operating
Report") in a form prescribed by the office of the United States Trustee of the
Department of Justice for the Northern District of Illinois, Eastern Division.
Exhibit 99.1 to this Current Report on Form 8-K contains the text of the
Operating Report.

The Company cautions readers not to place undue reliance upon the information
contained in the Operating Report. The information in the Operating Report was
not audited, however, in the opinion of the Company's management, the
information reflects all adjustments necessary for a fair presentation of the
results for the periods presented in accordance with generally accepted
accounting principles. There can be no assurance that the Operating Report is
complete. The Operating Report also contains information for periods which are
shorter or otherwise different from those required in the Company's reports
pursuant to the Exchange Act of 1934, as amended (the "Exchange Act"). Such
information may not be indicative of the Company's financial statements in its
reports pursuant to the Exchange Act and readers are cautioned to refer to the
Exchange Act filings.
