CVRD Signs Iron Ore Supply Contract with COSIPA

Rio de Janeiro, July 22, 2004 – Companhia Vale do Rio Doce (CVRD), the largest iron ore producer in the world, informs that It has signed an iron ore supply contract for sinter feed and lump with Companhia Siderúrgica Paulista (COSIPA), a subsidiary of Usiminas, which produces uncoated flat steel (slabs, plates, hot and cold rolled coil).

The contract is for an annual supply of 1.1 million ton of iron ore to COSIPA during three years. The Feijão and Fábrica mines, located in the west region of the Iron Ore Quadrangle, will supply the products to COSIPA.

This contract, signed in a moment of extraordinary global iron ore demand expansion, reflects CVRD ’s long-term commitment to the development of the Brazilian steel industry.

This press release may contain statements that express management’s expectations about future events or results rather than historical facts. These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those projected in forward-looking statements, and CVRD cannot give assurance that such statements will prove correct. These risks and uncertainties include factors: relating to the Brazilian economy and securities markets, which exhibit volatility and can be adversely affected by developments in other countries; relating to the iron ore business and its dependence on the global steel industry, which is cyclical in nature; and relating to the highly competitive industries in which CVRD operates. For additional information on factors that could cause CVRD’s actual results to differ from expectations reflected in forward-looking statements, please see CVRD’s reports filed with the Brazilian Comissão de Valores Mobiliários and the U.S. Securities and Exchange Commission.
