RECENT DEVELOPMENTS

The following discussion of developments since December 31, 2012 affecting Braskem should be read in conjunction with the description of the Brazilian petrochemical industry, the history of our company and the description of our business and strategy set forth in “Item 4: Information on the Company” and “Item 8: Financial Information—Legal Proceedings” included in our annual report on Form 20-F for the year ended December 31, 2012, filed with the SEC on April 8, 2013, which we refer to herein as the Braskem Annual Report.

The following is a summary of major transactions entered into, and other developments affecting us, since December 31, 2012.

Developments Relating to Pending and Proposed Capital Expenditure Projects and Acquisitions and Dispositions of Investments

Joint Venture with Styrolution

In October 2013, we signed a memorandum of understanding with Styrolution Group GmbH, or Styrolution, a global leader in the production of styrene, to assess the economic feasibility of forming a joint venture in Brazil. If approved, this joint venture would build and operate a plant with an expected annual production capacity of 100,000 tons of the copolymers acrylonitrile butadiene styrene and styrene acrylonitrile. We expect that the joint venture would market these copolymers to customers in Brazil and throughout South America. The memorandum of understanding contemplates that Styrolution would hold a 70% interest in the joint venture and be entitled to elect three board members, including the chairman of the board. Styrolution would contribute to the joint venture its expertise in developing and producing styrene, the necessary technology licenses and its existing acrylonitrile butadiene styrene and styrene acrylonitrile businesses in the region. The memorandum of understanding contemplates that Braskem would hold a 30% interest in the joint venture and be entitled to elect the remaining two board members. Braskem would contribute to the joint venture supply chain infrastructure and the site of the plant. The implementation of this joint venture is subject to, among other things, the negotiation of definitive agreements among the parties with respect to the joint venture and regulatory and antitrust approval. If this joint venture is implemented, we expect that construction will commence in early 2015 and that this plant would commence operations in 2017.

Acquisition of Interest in Odebrecht Comercializadora de Energia S.A.

In July 2012, we acquired 2,000 shares, or 20%, of the capital of Odebrecht Comercializadora de Energia. Odebrecht Comercializadora de Energia is also owned by Odebrecht Energia S.A., Odebrecht Agroindustrial S.A., Odebrecht Ambiental S.A. (currently Foz do Brasil S.A.) and Odebrecht Transport S.A, each with an equal interest of 20%. In July 2013, the shareholders of Odebrecht Comercializadora de Energia entered into a shareholders’ agreement governing the rights and obligations of all parties.

Material Raw Material Purchase and Product Sales Contracts

In July 2013, we entered into supply agreements with Innova S.A. under which we will supply to Innova S.A. (1) up to 205,000 tons of benzene and 73,800 tons of ethylene annually, and (2) up to 228,000 tons of high pressure vapor and 552,000 tons of low pressure vapor annually. These agreements expire in April 2023.

Investment in Metallocene-based LLDPE

In October 2013, we announced that we intend to invest approximately R$50 million in one of our polyethylene production lines in the Northeastern Complex to (1) expand the annual production capacity of this line by 30,000 tons and (2) convert 100,000 tons of the annual production capacity of this line to the production of metallocene-based LLDPE, which we intend to sell under the brand “Braskem Flexus.” We expect to sell this resin, which takes advantage of the development of more modern technology, primarily to manufacturers of plastic films. We expect this production line to begin operations in the first half of 2015.

LIBOR plus 2.73% to LIBOR plus 4.65%. To reduce the interest rate risk, the second tranche is hedged through several swap agreements. Interest on both tranches is payable quarterly in arrears and principal is amortized quarterly. The final maturity date of these loans is February 15, 2029 with amortizations beginning in April 2016. Braskem Idesa S.A.P.I. used the proceeds from the first disbursement to repay indebtedness incurred to fund the Ethylene XXI project before this disbursement, including the repayment of bridge loans with Braskem in the amount of US$648.8 million (R$1,449.8 million) and Idesa Group in the amount of US$216.3 million (R$483.3 million).

Legislative and Regulatory Changes Affecting Our Operations and Results

Legislative Change Affecting Accumulated ICMS

In May 2013, the State of São Paulo approved new legislation reducing ICMS on certain sales of naphtha, ethylene and propylene within the state. This reduction is conditioned upon certain requirements, including (1) the parties to the transactions must use a specified governmental data processing system to issue and account for tax documents, and they must regularly comply with related obligations and (2) the seller must be accredited by the applicable governmental authority. We believe that we comply with this legislation and, as a result, we expect our accumulated ICMS in the State of São Paulo to be reduced by approximately R$300 million between July 2013 and December 2014.
