'Dear Officer,
1. We refer you to the news article published on January 17, 2018, in the column of Ancelmo Gois of the newspaper O Globo, entitled: 'Kramer vs Kramer,' which contains the following statements:
'Braskem has sued Petrobras, accusing the state-owned oil company of unilaterally altering the conditions of the propylene supply contract. The oil company, as you know, is Odebrecht's minority partner in Braskem, although the stake is up for sale.'
2. In this regard, we request that the company confirm the veracity of the news report and, if affirmative, explain the reasons why it was not the subject-matter of a material fact notice and provide any other information deemed relevant on the topic.
3. We remind you that CVM Instruction 358/02, Article 4, Sole Paragraph establishes the requirement to question the managers and controlling shareholders of the Company, as well as any other persons with access to material acts or facts, to determine if such persons are aware of information that should be disclosed to the market.
4. Said response must be made via the Sistema Empresa.NET system, in the category: Notice to the Market, type: Clarifications of CVM/B3 Consultations, subject matter: News Report Published in Media, which should include a transcription of this official letter.
5. Please be advised that, as determined by the Company Relations Superintendent, in the exercise of their legal powers and, based on item II, Article 9 of Federal Law 6,385/76 and on CVM Instruction 452/07, a fine of one thousand reais (R$1,000.00) will be levied, without prejudice to other administrative sanctions, for non-compliance with the requirements of this letter, sent exclusively via e-mail, by January 19, 2018, notwithstanding the provisions in the Sole Paragraph of Article 6 of CVM Instruction 358/02.'

With regard to the above, Braskem clarifies to the market and its shareholders that it only has filed motions to suspend the period of limitation, seeking to preserve the Company's rights in the discussion of contractual disputes arising from the normal course of commercial relations between the two companies.
