Positive outlook for 2008 steel demand:

• Expected increases in maritime freight charges and the price of the main raw materials should motivate international steel producers to adjust upwards their own prices in order to preserve their operating margins;

• Growth in global demand for iron ore and steel products:

Intensive use of steel

Urbanization

Globalization

Opening of new markets

Demand growth driven by China, India, Eastern Europe, the Middle East and the other Asian countries;

Favorable outlook for CSN, given its self-sufficiency regarding practically all its inputs

BRIEF BACKGROUND		►	CSN was founded on April 9, 1941 and privatized in 1993
		►	As the first integrated flat steel producer in Brazil, CSN played a historical role in the country’s industrialization process
		►	Since its privatization up to now, CSN has invested more than US$ 4 billion raising total production capacity to 5.6 millions tons of crude steel per annum, improved quality and productivity levels and enhanced environmental protection

Self-sufficiency in practically all relevant raw materials for steel production - in special, “Casa de Pedra” captive iron ore mine and three power plants - along with equity participation or operating concessions of outstanding infra-structure assets, positions CSN not only as a truly low-cost producer but also one of the most independent, reliable and profitable steel producing systems, worldwide
