NOTICE TO THE MARKET

São Paulo, May 8, 2019 - BRASKEM S.A. (B3: BRKM3, BRKM5 and BRKM6; NYSE: BAK; LATIBEX: XBRK),  complementing the Notices to the Market and the Material Fact dated April 2, 5 and 15, hereby informs its shareholders and the market that it became aware, on the date hereof, of the Report no. 1 presented by the Brazilian Geological Service (CPRM) on the geological phenomenon that occurred in the city of Maceió, whose full version is available on the website www.cprm.gov.br .

This report indicates the occurrence (i) of destabilization of cavities resulting from sodium chloride extraction, which created a dynamic situation with reactivation of preexisting geological structures, subsidence and deformations in regions of the Pinheiro, Mutange and Bebedouro districts; and (ii) of instability in the Pinheiro district aggravated by the erosive effects caused by an increase in the infiltration of stormwater runoff in prexisting fractures in extremely erodible soil, accelerated due to lack of an effective stormwater runoff drainage network and of adequate basic sanitation, among other factors.

Braskem has been collaborating with the authorities to identify the causes, with the support of independent experts, and remains committed to implementing solutions. The Company will analyze the results of the report, as well as the appropriate measures to take regarding the matter.
