RELEVANT FACT

Transfer of control of Petroflex Indústria e Comércio S.A.

In furtherance to the information provided in the Relevant Fact disclosed on December 13^th, 2007, and in compliance with the provisions set forth in Section 157, Paragraph 4^th, of the Brazilian Federal Law No. 6,404/76 (“Law No. 6,404/76 “) and the Brazilian Securities Commission (Comissão de Valores Mobiliários - “CVM”) Instruction No. 358/02 (“Instruction No. 358/02”), Petroflex Indústria e Comércio S.A. (“Petroflex”), Braskem S.A. (“Braskem”), Unipar – União de Indústrias Petroquímicas S.A. (“Unipar”) and the other Petroflex’s shareholders parties to the Share Purchase Agreement executed on December 13^th, 2007 (the “Agreement”) (Braskem, Unipar and such other shareholders, the “Selling Shareholders”), and Lanxess Participações Ltda., as assignee of the rights and obligations undertaken by Lanxess Deutschland GmbH under the Agreement (“Lanxess”), announce to its shareholders and to the market in general that:

1. Lanxess and Petroflex’s Selling Shareholders concluded on this date the transference, to Lanxess, of 17,102,002 common shares and 7,416,602 preferred shares “class A” that represent 72.38% of Petroflex’s total common shares and 64.16% of Petroflex’s total preferred shares “class A”, respectively, and 69,68% of Petroflex’s total capital stock, in accordance with the terms of the Agreement. As a result of such transfers, the Shareholders’ Agreement relating to Petroflex dated April 10, 1992, as amended, was terminated on the date hereof.

2. The total acquisition price paid in cash by Lanxess to the Selling Shareholders on the date hereof was R$526,680,000.00 (five hundred and twenty-six million, six hundred and eighty thousand Reais) (“Acquisition Price”), corresponding to R$22.86 (twenty-two Reais and eighty-six cents) per common share and R$18.29 (eighteen Reais and twenty-nine cents) per preferred shares “class A”. As usual for transactions of this nature, the Acquisition Price is subject to an adjustment considering the variation of the working capital and net indebtedness of Petroflex, which may cause a reduction on the Acquisition Price, as provided for in the Agreement.
