**GUIDE TO USING THE WEBEX PLATFORM FOR ACCESS AND PARTICIPATION**

The Company clarifies that the Digital Webex Platform was chosen to carry out the Shareholders Meeting because it fulfills the requirements provided for in art. 28 Paragraph 1 of CVM Resolution 81, as it allows Shareholders the opportunity to express themselves and have simultaneous access to documents that have not been previously presented and that are presented during the Meeting. In addition, the Digital Platform allows full recording of the Meeting, as well as communication between participants, through the option "Chat" on the platform (see how to use this function in item 2.3 below).

Therefore, the Company makes the instructions below available to its Shareholders to serve as a guide / manual for using the Digital Platform on the day of the Meeting, in order to facilitate the participation of all those involved in the event.

Introductory Information

In order to have access to the Meeting, Shareholders must request an access link to the Meeting via email to <u>braskem-ri@braskem.com</u>, by April 24, 2023. The request must be accompanied by the necessary documents to participate in the meeting. Meeting, which were duly indicated in the Call Notice, in the Management Proposal and in this Manual for Participation in the Meeting.

The access to the Meeting via the Digital Platform will be restricted to shareholders or their representatives / attorneys-in-fact ("<u>Participants</u>"), members of the Company, and other persons whose presence is mandatory under the law or applicable regulation. The links to access the Digital Platform, containing the individual invitations, will be sent to the e-mail addresses that made the access request. Only one individual invitation will be sent per Participant.

The Company hereby informs that it will not authorize the participation in the Meeting of any Participant who has not requested the access link within the period indicated above, as well as for the Participants who request the link, but did so without presenting the necessary participation documents within the period above.

Participants who are accredited within the period indicated above undertake, as of now, to: (i) make use of individual invitations only and only for participation in the Meeting; (ii) not to transfer or disclose, in whole or in part, the individual invitations to a third party, whether a shareholder or not, the invitation being very personal and non-transferable; and (iii) do not record or reproduce, in whole or in part, nor transfer, to a third party, whether he is a shareholder or not, the content or any information obtained on the Digital Platform during the Meeting.

If a certain Participant, duly qualified, does not receive the link to access the Meeting up to 24 (twenty four) hours in advance of the opening hours of the Meeting (that is, until 3 p.m. on April 25, 2023), he / she must enter contact the Investor Relations department of the Company, by phone +55 (11) 3576-9531, no later than 12:00 noon on April 26, 2023, so that they can be sent back (or provided by phone) respective access instructions.

The Digital Platform is available for use via computer (desktop or laptops and the like) and via cell phone, through the Webex app, for Apple and Android phones. The Participant who chooses to participate in the Meeting via cell phone must download the Webex application on his mobile phone.

**Recommendations**

We suggest that Participants access the Digital Platform at least 15 (fifteen) minutes before the beginning of the Meeting, in order to avoid possible operational problems with the tool.

The Company recommends that Participants **test and familiarize themselves previously with the Digital Platform**, in order to avoid any surprises regarding the incompatibility of their electronic equipment with the tool, in addition to possible problems with its use on the day of the Meeting.

All Participants will start the Assembly with their microphones and videos disabled, and the event organizer must release them. Thus, after the presentation on each matter included in the Agenda of the Meeting, the Participant who wants to speak up must use the option "**Questions and Answers**" on the Digital Platform to register such request, so that the Participants will be given the floor in the order where requests are received by the Bureau. The manifestation will be exercised when the organizer of the event releases the audio of the requesting Participant.

As detailed in item 2 below, it should be noted that the platform's "Questions and Answers" function is not to be confused with the "Chat" function. Only through the "Questions and Answers" function will Participants be able to address the Bureau, including for the purposes of voting.

The "Chat" function can be used for communication between Participants.
