Vale on iron ore pricing

Rio de Janeiro, April 1, 2010 – Vale S.A. (Vale) announces that it has reached agreements on a new iron ore pricing regime with the majority of its clients, based on short-term market references and price changes on a quarterly basis. The agreements, permanent or provisional, reached 97% of our client base, which corresponds to 90% of the sales volumes under contracts.

The structural change in iron ore pricing is consistent with our previous announcements about the implementation of a new marketing policy, involving, among other issues, a more flexible approach towards pricing.
