Pursuant to CVM/SEP Circular Letter No. 2/2020 and considering the Annual General Meeting to be held on May 29, 2020 (“Meeting”), Braskem S.A. ("Braskem" or "Company") (Ticker B3: BRKM3, BRKM5 e BRKM6) notify its shareholders and the market that its shareholders GERAÇÃO FUTURO L. PAR FUNDO DE INVESTIMENTO EM AÇÕES, ALASKA BLACK MASTER FIA - BDR NÍVEL I, ALASKA RANGE FIM and ALASKA BLACK INSTITUCIONAL FIA ("Shareholders"), by correspondence dated as of April 30, 2020, appointed:

For the Board of Directors:

(i)Mr. Walter Luis Bernandes Albertoni, as candidate for effective member, to compose the chart of candidates for eventual separate election of the Company's Board of Directors at the Meeting, by shareholders with common shares, pursuant to article 141, paragraph 4, item "I", of Law No. 6,404, dated as of December 15, 1976, ("Brazilian Corporate Law"), if the necessary quorum required for using such prerogative is verified; and

(ii)Mr. Lírio Albino Parisotto, as candidate for effective member, to compose the chart of candidates for eventual separate election of the Company's Board of Directors at the Meeting, by shareholders with preferred shares, pursuant to article 141, paragraph 4, item "ii", of the Brazilian Corporate Law, if the necessary quorum required for using such prerogative is verified.

For the Fiscal Council:

(iii)         Mrs. Heloísa Belotti Bedicks and Mr. Reginaldo Ferreira Alexandre, as candidates for effective and alternate members, respectively, to compose the chart of candidates for eventual separate election of the Company's Fiscal Council at the AGM, by shareholders with preferred shares, pursuant to article 161, §4º, item "a", of the Brazilian Corporate Law, if requested under the terms of the law.

The résumés and further information of the candidates appointed by the Shareholders, as required in article 10 of the Brazilian Securities and Exchange Commission (“CVM”) Instruction No. 481, dated as of December 17, 2009 (“CVM Instruction 481/09”), are attached to this notice to shareholders as per Exhibit I.

In addition to the information provided in Exhibit I, provided by the Shareholders, the Company clarifies that, in accordance with article 18, paragraph 1, of the Company's Bylaws, and item 2 (viii), of the Internal Rules of the Board of Directors, the Board, with the support of the People and Organization Committee, evaluated the information regarding the candidates to the Board of Directors¹ and concluded that: (i) Mr. Walter Luis Bernardes Albertoni fulfill the independence requirements established in the Company's Global Compliance System Policy² and will be considered an independent board member, if elected ; and (ii) Mr. Lírio Albino Parisotto does not fulfill the independence requirements established in the Company's Global Compliance System Policy, as he is the Chief Executive Officer and Chairman of the Board of Directors of Videolar-Innova S.A., since this company has a commercial relationship with the Company in a magnitude that compromises the candidate's independence and will be considered a non-independent board member, if elected.

Also, under the terms of the applicable legislation, the name, the résumé and further information required by CVM Instruction 481/09 of the candidates appointed by the Company's controlling shareholder and by Petróleo Brasileiro S.A. - Petrobras to compose the Company's Board of Directors and Fiscal Council are included at the Management Proposal for the AGM, made available to the shareholders on April, 28^th at the Company's office located at Rua Lemos Monteiro, No. 120, 24^th floor, Butantã, in the City of São Paulo, State of São Paulo, ZIP Code 05501-050, and in the Company’s website (www.braskem-ri.com.br) and CVM’s website (www.cvm.gov.br).

Lastly, it is important to note that: (a)  the effective separate election of members of the Board of Directors, under the terms of article 141, paragraph 4 or paragraph 5, of the Brazilian Corporate Law, will depend on proof of uninterrupted ownership of the required shareholding, during the 3 (three) months period, at least, immediately prior to the date of the Meeting; and (b) the effective separate election of members of the Fiscal Council, under the terms of article 161, paragraph 4, of the Brazilian Corporate Law, will occur if the applicable legal requirements are fulfilled.
