RELEVANT FACT

In compliance with the terms of paragraph 4, article 157 of Law no 6,404/76 and CVM Resolution nº 358/2002, ARACRUZ CELULOSE S.A. ("ARACRUZ") announces that preliminary studies have been completed regarding the feasibility of the future construction of a new pulp production plant in the region of Governador Valadares (MG). The plant is expected to start operating until 2015 with a production capacity of 1.4 million tons/year, representing a potential investment of US$ 2.4 billion including land acquisition, silviculture and industrial investment. The studies indicate that the region's conditions are favorable to accomodate two additional pulp plants, each with a production capacity equivalent to the first plant.

In view of the results of these studies, covering the economic, social and environmental aspects of the project, ARACRUZ is taking steps to expand its forest base in the region and obtain the appropriate environmental licenses. Nevertheless, the effective implementation of the various steps of the project and the corresponding investments will depend on the future deliberations of the company’s Board of Directors, which will announce its decision at the opportune moment, taking into consideration, among other things, the prevailing economic situation and market, infrastructure and licensing conditions at the time.
