Braskem Announces Participation in Tax Debit Repayment Program

SAO PAULO, November 30 - BRASKEM S.A. (NYSE: BAK; BOVESPA: BRKM3, BRKM5 and BRKM6; LATIBEX: XBRK),
the leading company in the thermoplastic resins industry in Latin America and
third-largest resin producer in the Americas, in accordance with CVM
Instruction 358/02, announces to shareholders and the market that its
management has decided to include under the Tax Debit Repayment Program
offered by the Office of the General Counsel to the National Treasury and the
Internal Revenue Service (SRF) the pending administrative procedures and
lawsuits in which it claims (i) the right to IPI (federal VAT) tax credits on
purchases of raw materials subject to a zero tax rate ("Zero IPI"), (ii) the
benefits from the IPI Premium tax credits on export transactions ("IPI
Premium"), and (iii) the res judicata effect that exempts Braskem from paying
Social Contribution on Profit ("CSSL").

The total amount of the debits included in the repayment program is
approximately R$1.9 billion, given that the Company chose to pay in 12
monthly installments the Zero IPI and the IPI Premium, in the amount of R$1.1
billion, and the CSSL within 180 months, in the amount of R$795 million.

Management's decision was based on the very attractive benefits
introduced by Executive Order 470 and Federal Law 11,941/2009, which include
up to 90% reduction in interest payments and 100% reduction in penalties, as
well as the possibility of using accrued tax losses as currency for payment,
which in Braskem's case represents an average discount of 70% on the total
amount disputed.

Management's decision also took into account the complexity of the
matters that are the object of the administrative processes and lawsuits
described above.

With this decision, Braskem concludes its most relevant lawsuits without
compromising its financial strength.
