NOTICE

Pursuant to the provisions of article 12 of CVM Ruling No. 358/02, as amended by CVM Ruling 449/07, Odebrecht Investimentos em Infra-Estrutura Ltda., with its principal place of business at Praia de Botafogo, 300, 11th floor – part, CEP 22250-040, Rio de Janeiro – RJ, enrolled with the National Register of Legal Entities (CNPJ/MF) under No. 07.668.258/0001-00 (“OII”), and Belgrávia Empreendimentos Imobiliários S.A., with its principal place of business at Praia de Botafogo, 300, 11th floor – part, CEP 22250-040, Rio de Janeiro – RJ, enrolled with CNPJ/MF under No. 71.884.431/0001-06 (“Belgrávia”), notifies that the twenty million six hundred and eighty-five thousand eight hundred and seventy-two (20,685,872) class “A” preferred shares issued by Braskem S.A. (“Company”), representing 6.5% of the shares of such class, and 4.1% of the total capital of the Company previously held by OII, will be held as of this date by Belgrávia. Consequently, Belgrávia has become the holder of seventy-eight million five hundred and twelve thousand six hundred and seventy-three (78,512,673) class “A” preferred shares issued by the Company, whereas OII has zeroed its participation in the Company. It is important to inform that, besides such acquisition, there are no Company shares intended by Belgrávia. No affiliate or subsidiary of Belgrávia holds securities issued by the Company. No debentures convertible into shares are directly or indirectly held by Belgrávia or a person related to it, and except for the Shareholders’ Agreements filed at the Company’s headquarters, there is no other agreement or contract regulating the exercise of voting right or the purchase and sale of securities issued by the company in which Belgrávia or the person related to it is a party. Finally, it should be noted that such transaction does not alter the control composition or administrative structure of the Company, considering that both OII and Belgrávia belong to the control group of the Company, since they are directly or indirectly controlled by Odebrecht S.A.
