Answer: The management of Braskem S.A. (“Braskem” or “Company”) hired PricewaterhouseCoopers Auditores Independentes (PwC), established in the City of São Paulo, State of São Paulo, at Av. Francisco Matarazzo, 1400, enrolled in the National Register of Legal Entities (CNPJ/MF) under no. 61.562.112/0002-01, originally registered with the Regional Accounting Council of the State of São Paulo under no. 2SP000160/O-5 and secondarily with the Regional Accounting Council of the State of Rio de Janeiro under no. 2SP000160/O-5 "F" RJ, to prepare the appraisal of shares issued by Quattor Participações S.A. (“Quattor”), at its equity book value, in order to determine Braskem’s capital increase resulting from the merger of shares of Quattor into Braskem.

Furthermore, Braskem’s management hired Banco Bradesco BBI S.A., a financial institution enrolled in CNPJ/MF under no. 06.271.464/0073-93, with its principal place of business at Av. Paulista nº 1.450, 8º andar, City and State of São Paulo (“Bradesco BBI”) to prepare, on an independent basis, an appraisal of the economic value of Braskem’s and Quattor’s shares, the result of which served as a basis to determine the replacement ratio applicable to the merger of shares.

2.         Describe the qualification of the recommended appraisers

Answer: PwC was nominated by Braskem’s management to issue the appraisal report of shares issued by Quattor at its equity book value, first because it is the company which audits Quattor, which makes it the most qualified company to confirm Quattor’s net worth, as well as to guarantee synergies among evaluations carried out recently and such equity appraisal. Additionally, PwC has great experience in doing this type of work, with several similar reports filed in the Securities Commission.

Braskem’s management has chosen Bradesco BBI to issue the economic and financial appraisal report of shares issued by Quattor and Braskem, taking into consideration Bradesco BBI’s great experience in developing Mergers and Acquisitions (“M&A”), Variable and Fixed Income transactions, Structured Transactions and Funding of Projects.

It is the lead company in its business, ranking first in terms of announced M&A transactions values and number of completed M&A transactions in Brazil in the last twelve months, according to the rank published by the Brazilian Financial and Capital Markets Association [Associação Brasileira das Entidades dos Mercados Financeiro e de Capitais](“ANBIMA”) on March 31 2010.
