<B>COMPANHIA SIDER&#218;RGICA NACIONAL</B> (&#147;CSN&#148;), pursuant to Article 157 of Law 6,404/76 and CVM Instruction 358/02, hereby informs its shareholders and the general public that on July 20, 2007, its wholly-owned subsidiary NACIONAL MIN&#201;RIOS S.A.
(&#147;NAMISA&#148;) entered into a purchase agreement with the shareholders of Cia. de Fomento Mineral e Participaes  CFM (&#147;CFM&#148;) for the acquisition of 100% of the shares issued and outstanding by CFM.</P>
<P>
CFM explores various iron ore mines and owns ore processing facilities in the state of Minas Gerais. CFM sold approximately 3.6 million tonnes of iron ore in 2006 and in the first half of 2007 sold approximately 2.7 million tonnes. The company is
enlarging the production capacity of its facilities and in 2008, CFM&#146;s sales are expected to reach 8 million tonnes of iron ore.</P>
<P>
The acquisition price may amount up to US$440 million, of which US$100 million was paid upon the execution of the purchase agreement, and US$250 million will be paid on August 1<SUP>st</SUP>, 2007. The remaining US$90 million may be
paid in four installments within two years upon the fulfillment of certain conditions of the purchase agreement. The financial resources for the acquisition of CFM shall be obtained with funds raised in the financial markets.</P>
<P>
The acquisition of CFM by NAMISA represents another step in CSN&#146;s strategy of conquering a larger share of the mining sector, thus, increasing its potential of creating value for its shareholders</P>
