<B>COMPANHIA SIDER&Uacute;RGICA NACIONAL</B> (&#147;<B>CSN</B>&#148;) hereby informs its shareholders and the public that, on this date, it signed two new long-term supply contracts with Gulf Industrial Investment Co. (E.C.) (GIIC), a company
headquartered in Bahrain, to supply pellet feed produced by the Casa de Pedra Mine and the mines operated by NACIONAL MIN&Eacute;RIOS S.A., CSN&#146;s wholly-owned subsidiary. The contracts envisage the supply of at least 183,300,000 (one hundred
eighty-three million, three hundred thousand) tonnes of pellet feed over 25 (twenty-five) years, starting from 2009.  The contractual terms, including those relating to price and price adjustment criteria, are in line with the market practices in
the international iron ore industry. </P>

CSN believes that these two new contracts reaffirm its objective of expanding its mining operations and underline its capacity, and reliability, to supply high quality iron ore. </P>
