RELEVANT FACT

Braskem S.A. (“Braskem”), Suzano Petroquímica S.A. (“Suzano Petroquímica”) and Politeno Indústria e Comércio S.A. (“Politeno”), pursuant to CVM Instruction No. 358/02, hereby inform its shareholders and the market that, Braskem, as purchaser and Suzano Petroquímica, through its subsidiary SPQ Investimentos e Participações Ltda. (“SPQ”), together with Sumitomo Chemical Company, Limited and Itochu Corporation (“Japanese Group”), as sellers, and having Politeno as intervening party, entered on this date, into an agreement for purchase by Braskem, of all the shares owned by SPQ and Japanese Group in the total share capital of Politeno.

Upon the closing of this transaction, Braskem, which already owned 35.0% of the total voting share capital and 33.4% of the total share capital of Politeno, will now own 100% of the voting share capital and 96.2% of the total share capital of Politeno, a company with a production capacity of 360,000 tons of polyethylene per year, located at the Petrochemical Pole of Camaçari, State of Bahia, and owner of equities interest at other companies.

The initial amount to be paid by Braskem to SPQ and to Japanese Group was calculated based on a down payment in Reais equivalent to US$ 111,275,800.00, of which US$ 60,629,210.00 is to be paid to SPQ and US$ 50,646,590.00 to Japanese Group. The final value of the sale will be calculated pursuant to a formula that will measure the performance of Politeno during the 18-month period after the sale. The use of such price formula will ensure that the interest of all parties is aligned and that the final price for the shares is fair.

The conclusion of this transaction represents another step into the straightness of the Brazilian petrochemical sector, creating conditions that will allow the growth and the increase in competitiveness of the sector in the country, including through expansions and new investments. At the same time, it confirms Braskem’s and Suzano Petroquímica’s beliefs in the positive performance of the petrochemical sector and their willingness to actively participate of the sector’s consolidation.
