MATERIAL FACT ------------- COMPANHIA SIDERURGICA NACIONAL Publicly Held Corporation Rua Sao Jose n. 20, Grupo 1602, parte Rio de Janeiro/RJ CNPJ n. 33.042.730/0001-04 COMPANHIA SIDERURGICA NACIONAL ("CSN") hereby informs its shareholders and the public that on October 24, 2006, CSN executed the Agreement and Plan of Merger with Wheeling-Pittsburgh Corporation ("WPC"), by which CSN will contribute certain assets, represented by its subsidiary Companhia Siderurgica Nacional, LLC, located in the United States in Terre Haute, Indiana ("LLC"), in exchange for 49.5% of the shares of the new company resulting from the merger of the operations of WPC and LLC. The new company will have its shares listed on a U.S. stock exchange. This transaction also involves a loan by CSN, in the amount of US$ 225 million, which is convertible into an additional 14.5% of the equity of the new company subject to the approval of the United Steelworkers union. Subject to this approval, the total participation of CSN in the total capital of the new company may be increased to up to 64%. The implementation of the Agreement and Plan of Merger depends on certain conditions, among them the approval by the local competition authorities and by the stockholders of WPC at a meeting of the stockholders to be held at the beginning of 2007. This transaction reinforces the commitment of CSN with its internationalization strategy, expanding its operations abroad.
