Press Release

CSN announces that it has today approached the Board of Corus regarding a proposal to acquire the Company at a price of 475 pence per ordinary share in cash. Any potential offer is subject to certain pre-conditions, all of which CSN reserves the right to waive, including completion of confirmatory due diligence satisfactory to CSN, finalisation of financing arrangements and a recommendation from the Board of Corus.

—	Enable Corus to secure supply of high quality, low cost iron ore from CSN’s Casa de Pedra mine, one of the largest captive mines in the world.
—	In time, provide Corus with access to increasing quantities of low cost semi-finished steel for further processing across its downstream facilities in Europe.
—	Allow Corus greater access to fast growing markets as well as providing opportunities for cross-selling the enlarged portfolio of products.
—	Create the potential to capture significant synergy benefits through global procurement savings and allow for the sharing of best practices.
—	Give CSN the ability to leverage Corus’exceptional research and development and engineering expertise across the combined group.

The combination of CSN and Corus would create a top five global steel group with 24 million tons of annual steel production and, by 2010, approximately 50 million tons of annual iron ore production.

CSN intends to finance the acquisition of Corus through a combination of existing financial resources and the proceeds of new debt facilities to be underwritten by a bank syndicate comprised of Barclays Bank PLC, Goldman Sachs Credit Partners L.P. and BNP Paribas and/or their designated affiliates.

“A combination of CSN and Corus would create a global powerhouse with market leading positions and exceptional distribution networks across both developed and emerging markets. With its vertically integrated structure and industry leading margins, the enlarged group would become a leader in the global steel industry, fully self-sufficient in iron ore and ideally positioned to take advantage of ongoing consolidation.

We have great respect for the accomplishments of the Corus Board and management, including their achievements in the Restoring Success programme. With their support, we believe we can swiftly deliver the most attractive proposal to Corus and its shareholders.”

“We are pleased with the strong backing we have received for our proposal from a group of leading international banks to add to our own balance sheet strength and cash generation capabilities. A major proportion of the new funding would be non-recourse to CSN.”

This announcement does not constitute an announcement of a firm intention to make an offer for Corus, as defined under Rule 2.5 of the Takeover Code (the “Code”) and, as such, there can be no certainty that any offer will be made even if the pre-conditions are satisfied or waived.

Under the provisions of Rule 8.3 of the Code, if any person is, or becomes, “interested” (directly or indirectly) in 1% or more of any class of “relevant securities” of Corus, all “dealings” in any “relevant securities” of that company (including by means of an option in respect of, or a derivative referenced to, any such “relevant securities”) must be publicly disclosed by no later than 3.30 pm (London time) on the London business day following the date of the relevant transaction. This requirement will continue until the date on which the offer becomes, or is declared, unconditional as to acceptances, lapses or is otherwise withdrawn or on which the “offer period” otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an “interest” in “relevant securities” of Corus, they will be deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the Code, all “dealings” in “relevant securities” of Corus by CSN or any of its “associates”, must be disclosed by no later than 12.00 noon (London time) on the London business day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose “relevant securities” “dealings” should be disclosed, and the number of such securities in issue, can be found on the Takeover Panel’s website at www.thetakeoverpanel.org.uk (http://www.thetakeoverpanel.org.uk).

“Interests in securities” arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an “interest” by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the Code, which can also be found on the Panel’s website. If you are in any doubt as to whether or not you are required to disclose a “dealing” under Rule 8, you should consult the Panel.
