2.3. <u>Compensation of Directors and Committee Members</u>. The Shareholders also irrevocably and irreversibly agree to amend Clause 6.6 of the Agreement so that the compensation due to regular members of the Board of Directors who also serve on Braskem's Committees (or even on the Executive Board) becomes cumulative. Consequently, Clause 6.6 of the Agreement shall now read as follows:

*"6.6 <u>Compensation of Directors and Committee Members</u>. The compensation due to the full members of the Board of Directors by reason of the exercise of their functions on such body and, as applicable, on any of its Committees (or even on the Executive Board), shall be cumulative.*"

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.2.1 Consensus between the Parties shall not be
required for the nomination of their members to the Board of Directors. If the total number of Board members that the Parties may elect

undertake to use their votes in an organized and joint manner to comply with the provisions of this Agreement regarding the election of
members of the Board of Directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.2.5 The Parties undertake not to nominate as

a given election and/or reelect the Chairman and Vice-Chairman of the Board of Directors, it being understood that the Party that nominates
the Chairman of the Board of Directors may not, during the same period, nominate the CEO.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.2.10 The Parties may replace the directors nominated by them at any time, at their sole discretion, without
the need for justification. Should any of the Parties wish to replace an elected director, the other Party undertakes, on its own behalf
and through its nominated Directors, to take all necessary steps to ensure that the removal and/or replacement is implemented as soon
as possible following a request from the other Party to that effect, including guiding and instructing its representatives on the Board

between the Parties for each nomination. Subject to the provisions of <u>Clause 6.1.1</u>, the Board of Directors of Braskem shall be
responsible for allocating nominees to each of the Committees, taking into account, for such purpose, the experience and specific competencies
of each member, *vis-à-vis* the responsibilities of each Committee, without preventing the same nominee from serving on more
than one Committee. For the sake of clarity, the Committees may also include persons who are not members of the Board of Directors or
even employees of the Company. The coordination of the Committees indicated in items (i) through (iv) of <u>Clause 6.3</u> above shall
alternate between representatives of the Parties, with 2 (two) coordinators from Petrobras and 2 (two) from the Fund, with subsequent
nominations for each Committee made on a rotating basis. The coordination of the Committee indicated in item (v) of <u>Clause 6.3</u> above shall be held by an external member who is not a representative of the Parties.

levels and powers of the Officers, as well as the list of matters within the authority of the Board of Directors that must be reviewed
and resolved by the Executive Board, as a collegiate body, before being submitted for review by the Board. In reinforcement of the parity
principle adopted herein at the other levels of governance of the Company, it is agreed that, for purposes of applying the authority and
representation rules of Braskem by the Officers before third parties (as set forth in the bylaws and/or internal rules), the binding of
the Company shall require the joint approval and signature of an Officer nominated by Petrobras and an Officer nominated by the Fund.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.4.2 The Executive Board shall act as a Collegiate
body in the situations set forth in the bylaws or internal regiments of Braskem approved by consensus among the members of the Board of
Directors nominated by the Parties, <u>it being understood</u>, <u>further</u>, that the Officers of Braskem may not submit matters for
resolution by the Board of Directors without such matters being previously submitted to: (i) the review, knowledge and collegiate opinion
of the Executive Board, subject to the authority levels defined in the Bylaws and in the Executive Board regiment approved by the Board
of Directors; and (ii) the opinion of the relevant advisory committees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.4.3 The Executive Board of Braskem shall be composed
of Officers nominated by the Parties, it being understood that Petrobras and the Fund shall have the right to nominate the same number
of Officers, without the need of consensus between the Parties for each nomination, but subject to the requirements set forth and detailed
in the internal regiment of the People Committee, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The nominations for each of the positions of CEO and Corporate Affairs Officer of Braskem shall be made on a rotating basis alternating between the Parties, subject to the transitional provisions of <u>Clause 6.7</u> below. The Parties may, however, by mutual agreement at a Preliminary Meeting, waive the rotation for a given election.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Without alternating rotation between the Parties:

(b.1) Petrobras shall have the right to nominate the following Officers: (i) Engineering, Technology and Innovation Officer; (ii) Consumer Market and Logistics Officer; and (iii) Chief Operating Officer; and

(b.2) the Fund shall have the right to nominate the following Officers: (i) Chief Financial and Investor Relations Officer; (ii) Transformation Officer; and (iii) General Counsel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Out of an abundance of caution and in the interest of better governance, in the event that the Company's bylaws, internal regiment of the Executive Board or a Board of Directors resolution assigns the CEO (or another Officer nominated by Petrobras) the primary responsibility for raw material procurement, such responsibility shall also alternate between the CEO and the Corporate Affairs Officer (or another officer nominated by the Fund), so as to remove such responsibility, at all times, from an Officer nominated by Petrobras.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.4.4 The CEO may at any time submit to the Board
of Directors a proposal for the removal of any Officer of the Company. The resolution on the removal shall be preceded by the analysis
and opinion of the People and Organization Committee. The removal proposal shall be approved by consensus between the Parties through
their representatives on the Board of Directors, subject to the rules and procedures established for nomination under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.4.5 <u>Transformation Officer</u>. The Transformation
Officer shall be responsible for coordinating and leading the implementation of all activities of the Company's financial transformation
process, observing the recommendations made by the Transformation Committee. For the sake of clarity, the internal rules of the Executive
Board shall establish the specific authority levels and powers of the Transformation Officer, in addition to those indicated in <u>Clause 6.4.6</u> below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.4.6 <u>Transformation Committee – Executive Board</u>. In addition to the advisory Committees to the Board of Directors indicated above, the Parties undertake, on their own behalf
and through their nominated officers, to create a Transformation Committee, a non-statutory body linked to the Executive Board, composed
of 4 (four) Officers, of which 2 (two) nominated by Petrobras and 2 (two) nominated by the Fund (of which (1) one necessarily being the
Transformation Officer), without the need of consensus between the Parties for each nomination (which may be replaced from time to time).
The Transformation Officer shall serve as coordinator of the Transformation Committee, being responsible for calling, setting the agenda
and chairing the meetings of such Committee – without prejudice to the possibility of meetings being called by the other members,
pursuant to rules to be set forth in the internal regiment of the Transformation Committee – subject also to the other

specific powers set forth in <u>Clause 6.4.5</u> and in the internal regiment of the Executive Board and/or the Transformation Committee. The Transformation Committee, intended to last for the Lock-Up Period (unless otherwise agreed at a Preliminary Meeting in the future), shall be responsible for monitoring and overseeing the implementation and execution of Braskem's turnaround plans led by the Transformation Officer, pursuant to terms to be detailed in its internal regiment or those of the Committee, as applicable, which may be amended from time to time by the Board of Directors. The Transformation Committee may also appoint a PMO (project management officer), either as an adjunct officer position or equivalent reporting position, or through the engagement of a specialized consulting firm, to respond to and support the Transformation Committee directly in the execution and coordination of work across all areas of the Company (as well as the Subsidiaries and Investees).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.4.7 <u>Compliance and Conformity Officer</u>.
The Company shall also have a Compliance and Conformity Officer, of a non-statutory nature, appointed by mutual agreement between the
Fund and Petrobras, who shall report hierarchically and functionally (solid line) to the Board of Directors and the Compliance and Statutory
Audit Committee (CAE), and, administratively (dotted line), to the Chief Executive Officer (CEO). For clarity, the Executive Board's
internal regulations shall establish the specific authority and responsibilities of the Compliance and Conformity Officer.

6.5 <u>Fiscal Council</u>. Braskem shall have a permanent Fiscal Council, composed of 5 (five) full members and their respective alternates. The Parties shall exercise their voting power to elect the largest possible number of members of the Fiscal Council. If the Parties elect an odd number of members to the Fiscal Council, there shall be a rotation in the election of the additional member. Persons who hold management positions (whether as director, officer or who hold any other function) in petrochemical companies that may be considered competitors shall not be elected to the Fiscal Council of Braskem.

6.6 <u>Compensation of Directors and Committee Members</u>. The compensation due to the full members of the Board of Directors by reason of the exercise of their functions on such body and, as applicable, on any of its Committees (or even on the Executive Board), shall be cumulative.

6.7 <u>Transitional Provisions on Management</u>. In order to give effect to the preceding provisions, as well as to ensure an adequate transition of management in the context of the entry into force of this Agreement, the current terms of office and the corresponding bylaw amendments, the Parties agree on the following transitional provisions:

7.2 <u>Right of First Refusal on the Disposal of Shares</u>. The Parties mutually grant each other a right of first refusal for the acquisition of the Bound Shares or subscription rights for new Shares owned by them, in the event that any of the Parties intends, in

any manner or under any title, to directly Transfer the entirety of its interest in Braskem, whether through a single transaction or a series of transactions. If a Shareholder ("<u>Offering Shareholder</u>") receives a proposal from a Third Party interested in acquiring all of the Bound Shares owned by it ("<u>Proposal</u>"), the Offering Shareholder shall send a written notice ("<u>Offer Notice</u>") to the other Shareholder ("<u>Offered Shareholder</u>"), who shall have the right of first refusal to acquire such Bound Shares ("<u>Offered Shares</u>") or to subscribe for the new Shares, on the same terms and conditions of the Proposal ("<u>Right of First Refusal</u>"). The exercise of the Right of First Refusal shall be subject to the procedures described below and shall only be valid if exercised with respect to all Bound Shares subject to the Proposal.

First Refusal with respect to the entirety of the Offered Shares subject to the Proposal, at the same price and subject to the same terms
and conditions of the Proposal, or (b) whether it will designate a Third Party to exercise the Right of First Refusal with respect to
the entirety of the Offered Shares subject to the Proposal, in its own name, accompanied by the Third Party's agreement with the
terms and conditions of the Proposal; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) whether it will waive the Right of First
Refusal, it being understood that the absence of the Decision Notice by the deadline shall be construed as a waiver of the Right of First
Refusal and, further, whether or not it will exercise the Tag-Along Right as set forth in <u>Clause 7.3</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.2.3 If the Offered Shareholder exercises the
Right of First Refusal to acquire the Offered Shares subject to the Offer Notice, the Offered Shareholder and the Offering Shareholder
shall execute, within a maximum period of 30 (thirty) calendar days from the sending of the Decision Notice, the documents necessary to
formalize the Transfer of the Offered Shares and submit it, if applicable, within the same period, for the approvals of the Administrative

The Transfer of the Offered Shares shall be completed after the fulfillment of the conditions precedent, including the Regulatory Approval,
as applicable, limited to the period provided for in the instrument executed between the Offered Shareholder and the Third Party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.2.4 In the event of waiver of the exercise of
the respective Right of First Refusal, the Offered Shares may be freely transferred to the interested Third Party. To this end, the interested
Third Party and the Offering Shareholder shall execute, within a maximum period of 30 (thirty) calendar days from the sending of the Decision
Notice, the documents necessary to formalize the Transfer of the Offered Shares and submit it, if applicable, within the same period,
for Regulatory Approval. The Transfer shall be completed after the fulfillment of the conditions precedent, including the Regulatory Approval,
as applicable, limited to the period provided for in the instrument executed between the Offering Shareholder and the interested Third
Party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.2.5 If the Offering Shareholder and the interested
Third Party do not execute the documents mentioned in <u>Clause 7.2.4</u> above within the period set forth therein, the procedure set
forth in this Clause shall be repeated, with the Right of First Refusal being granted again to the other Parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.2.6 The acquirer of the Offered Shares subject

non-compliance with this provision shall automatically render the disposal ineffective.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.2.7 The Company and/or the Share Registrar, as
applicable, shall refuse and deny the registration, annotation or any notation in the book-entry systems and/or corporate books, as well
as refrain from recognizing any effect of acts performed in violation of the provisions of this Agreement, including with respect to the
Transfer, encumbrance or exercise of rights inherent to the Bound Shares, until the conditions and restrictions set forth herein are fully
observed.

7.3 <u>Tag-Along Right</u>. As an alternative to the exercise of the Right of First Refusal, the Party receiving the Offer Notice (the Offered Shareholder defined in <u>Clause 7.2</u>)

shall have the right to require that such disposal of Bound Shares by the Offering Shareholder include the Bound Shares then held by the Offered Shareholder in the same proportion of the Shares of the Offered Shareholder that are the subject of the Offer Notice, at the same price and on the same conditions set forth in the Offer Notice ("<u>Tag-Along Right</u>"). The exercise of the Tag-Along Right shall be subject to the procedures described below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.3.1 If it wishes to exercise its Tag-Along Right,
the Offered Shareholder shall do so by notice to be sent to the Offering Shareholder within the Right of First Refusal exercise period
(" <u>Notice of Exercise of Tag-Along Right</u> "). The exercise of the Tag-Along Right shall preclude the exercise of the Right
of First Refusal and vice versa.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.3.2 Once the Tag-Along Right is exercised, as
provided in <u>Clause 7.3.1</u> above, the disposal to a bona fide Third Party shall have as its object not only all the Offered Shares
owned by the Offering Shareholder, but also the Bound Shares owned by the Offered Shareholder, which shall likewise be acquired by the
interested Third Party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.3.3 In the event of exercise of the Tag-Along
Right, the parties shall execute, within a maximum period of 30 (thirty) calendar days from the sending of the Notice of Exercise of Tag-Along
Right, the documents necessary to formalize the Transfer of the Bound Shares and submit it, if applicable, within the same period, for
Regulatory Approval. The Transfer of the Bound Shares shall be completed after the fulfillment of the conditions precedent, including
the Regulatory Approval, as applicable, limited to the period provided for in the instrument executed between the respective parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.3.4 The exercise of the Tag-Along Right and,
if applicable, the definitive documents to be executed with respect to the transfer of the Bound Shares owned by the Offering Shareholder,
shall not bind the Offered Shareholder to be jointly and severally liable for any obligations of the Offering Shareholder, such as, without
limitation, representations or warranties, indemnification, non-compete or non-solicitation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.3.5 It is hereby established that the failure
to respond or an untimely response regarding the exercise of the Tag-Along Right by the Offered Shareholder shall be deemed a waiver of
the exercise of the Tag-Along Right. In this case, the Offered Shares owned by the Offering Shareholder may be freely transferred to the
interested Third Party, provided that: (a) the Offered Shareholder has not exercised its Right of First Refusal, and (b) such transfer
is completed within the periods provided in this Agreement. To this end, the Offering Shareholder and the interested Third Party shall
execute, within a maximum period of 30

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(thirty) calendar days from the non-exercise by the Offered Shareholder of its Right of First Refusal, the documents necessary to formalize the Transfer of the Offered Shares and submit it, if applicable, within the same period, for Regulatory Approval. The Transfer of the Offered Shares shall be completed after the fulfillment of the conditions precedent, including the Regulatory Approval, as applicable, limited to the period provided for in the instrument executed between the respective parties.

Target has not been achieved, the Fund may, without triggering the application of <u>Clause 10.2(b)</u>, Transfer any quantity of Bound
Shares to one or more Third Parties provided that :

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) it observes the Right of First Refusal and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the acquirer of the Bound Shares adheres
to the terms of this Shareholders' Agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) in the case of a Third Party acquirer that

a justified manner, in writing within 60 (sixty) days from a notice to that effect by the Fund, it being understood that the absence of
a response within such period shall mean tacit and irreversible acceptance by Petrobras.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.4.3 After the Lock-Up Period *,* the Bound
Shares subject to any Transfers through stock exchange sales shall not be classified as Bound Shares after the Transfer, ceasing to be

purposes of this Agreement, as a single shareholder together with the assignor; and (3) the assignees shall not be party to this Agreement.

Bound Shares made by the Fund, in any quantity, in a stock exchange or organized over-the-counter market environment, whether in ordinary
stock exchange transactions, through block trades or in a secondary public offering of shares of the Company (follow-on), shall be permitted
without observance of the Right of First Refusal or the Tag-Along Right and, in this case, the need for resolution pursuant to <u>Clauses 4.4</u> and <u>4.5(xxv)</u> above shall be observed, without Petrobras being obligated to vote favorably for such follow-on.

The Parties agree that the Right of First Refusal and the Tag-Along Right shall not apply in the event of a Transfer by any Shareholder, at any time (including during the Lock-Up Period), of any quantity of Shares, to a subsidiary 100% (one hundred percent) owned by the assigning Party (in both political and economic terms), provided that: (a) assignor and assignee agree to be jointly and severally bound and responsible for all obligations established in this Agreement and/or in other contracts or documents relating to the Company that have been executed in connection with the covenants entered into by the Shareholders in this Agreement; (b) the assignee adheres to this Agreement in writing (it being understood that, in the event of more than one assignee, the group of assignees shall be considered as a single block for purposes of exercising the rights and obligations provided for herein); and (c) all Governmental Authorizations and Third Party authorizations that may be necessary to implement the Transfer of the interest are

obtained. This scenario, as well as the others permitted in the subclauses below, the "<u>Permitted Transfers</u>".

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.6.1 At any time, including during the Lock-Up
Period, the following shall be permitted: (a) any direct or indirect Transfer of any quantity of quotas issued by the Fund by the Quotaholder,
and/or by its ultimate quotaholders; (b) Transfer of subscription rights, or issuance, of quotas issued by the Fund to holders of
claims against the Fund, so as to allow the conversion of such claims into quotas issued by the Fund; (c) Transfer for consolidation of
ownership of the Bound Shares in the process of enforcement of a Permitted Guarantee when it constitutes a fiduciary assignment; (d) Transfer
of Bound Shares privately or on the stock exchange (including through block trade or follow-on) of any quantities of Bound Shares, in
one or more transactions, to any Financial Investor, provided that such Transferred Bound Shares are immediately used for the purpose
of payment in kind of quotas of the Fund by such Financial Investor, which shall once again be immediately bound to this Agreement; and
(e) Transfer of Bound Shares to the Quotaholder and the other quotaholders of the Fund, in the event of liquidation, at any time, of the
Fund.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.6.2 The Permitted Transfers provided for in <u>Clauses 7.6.1(a)</u>, <u>(b)</u>, <u>(c)</u> and <u>(d)</u> above: (a) are not subject to the Right of First Refusal or the Tag-Along Right, except
as provided in <u>Clause 7.6.4</u>; (b) do not waive the continued compliance with <u>Clause 7.5</u>; and (c) do not trigger <u>Clause 7.8</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.6.3 In the event that the Permitted Transfer
provided for in <u>Clause 7.6.1(e)</u> occurs, the Fund shall, prior to the effective Transfer of Bound Shares to the Quotaholder or the
other quotaholders of the Fund, inform Petrobras of the identity of its quotaholders, the number of Bound Shares that will be allocated
to each in the liquidation and the date of acquisition of their quotas in the Fund. If any of the quotaholders has acquired 10% (ten percent)
or more of the quotas of the Fund in the 12 (twelve) months immediately preceding the liquidation of the Fund, then for such Transfer
to occur with respect to such quotaholders, the Right of First Refusal (<u>Clause 7.2</u>) and the Tag-Along Right (<u>Clause 7.3</u>)
shall apply. For the sake of clarity, the Transfer provided for herein shall not trigger the application of <u>Clause 10.2 (b)</u> provided
that the requirement of <u>Clause 7.6.5</u> below is met.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.6.4 The Transfer to any Third Party *after* the consolidation of ownership as part of the enforcement process of the Permitted Guarantee under <u>Clause 7.6.1(c)</u> shall be subject
to the Right of First Refusal (<u>Clause 7.2</u>) and the Tag-Along Right (<u>Clause 7.3</u>).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.6.5 In the case of <u>Clauses 7.6.1(c)</u> and <u>(e)</u>, the respective assignee(s) shall adhere to this Agreement in writing, it being understood that in each Transfer, the group

of the respective assignee(s) and, in the case of a partial Transfer, the assignor, shall be considered as a single block for purposes of exercising the rights and obligations provided for herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.6.6 For the avoidance of doubt, subject to the
other terms and conditions set forth in <u>Clauses 7.6</u> through <u>7.6.5</u>, the Permitted Transfers under <u>Clauses 7.6</u> (*caput*), <u>7.6.1(a)</u>, <u>(b)</u>, <u>(c)</u>, <u>(d)</u> and <u>(e)</u> and <u>7.6.3</u> shall not trigger the application of <u>Clause 10.2 (b)</u> as they do not result in a reduction of the total Bound Shares held (individually or collectively) by the Fund and/or its assignees
and successors in the Permitted Transfers.

7.7 <u>Non-Compliance with Fund Obligations During the Agreement Term</u>. The Fund shall maintain during the entire term of this Agreement full compliance with the obligations provided in <u>Clauses 7.5 (i)</u> through <u>(ix)</u>. Any non-compliance with any of <u>Clauses 7.5(i)</u> through <u>(ix)</u> (including as a result of any enforcement of guarantees by third parties) shall require the prior consent of Petrobras. In the event of non-compliance with <u>Clauses 7.5 (x)</u> or <u>(xi)</u>, Petrobras may require the quotaholders of the Fund to convene a deliberative meeting for the replacement of IG4 Sol. as specialized consultant of the Fund and of its appointed members to the Investments Committee of the Fund, with the appointment of a new consultant and members of the Investments Committee, chosen by mutual agreement with Petrobras. Non-compliance with the obligation set forth in this <u>Clause 7.7</u> shall be subject to the specific enforcement provided for in <u>Clause 14.9</u> below, without prejudice to adequate indemnification for losses and damages.

7.8 <u>Indirect Disposal by Change of Control</u>. The direct or indirect modification of the Control of a Shareholder, whether arising from the direct disposal of shares of such Shareholder, or from other corporate transactions such as merger, spin-off or amalgamation, except in the case of a Transfer arising from hereditary succession, shall entail the indirect disposal of Bound Shares of Braskem ("<u>Indirect Disposal by Change of Control</u>"). For the avoidance of doubt, Permitted Transfers shall not constitute, under any circumstances, an Indirect Disposal by Change of Control. The Party whose interest is indirectly disposed of shall be obligated to: (a) notify the other Party of the disposal ("<u>Notice of Indirect Disposal by Change of Control</u>"); and (b) individualize the value attributed solely to Braskem in the context of such transaction or, alternatively, when the Bound Shares are the only assets subject to the Indirect Disposal by Change of Control, indicate the price offered by the Third Party for the acquisition of indirect Control, which shall, in this case, be the exercise price of the Indirect Tag or the Indirect Acquisition Right.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.1 The Notice of Indirect Disposal by Change
of Control shall be sent within 30 (thirty) Business Days from the completion of the Change of Control and shall contain, at a minimum:
(i) the date on which the indirect disposal occurred; (ii)

the complete identification of the new Controller of the Shareholder (including complete information on its economic group); (iii) detailed information on the quantity of Bound Shares that were disposed of and the terms and conditions of the transaction; and (iv) the individualized price attributed to the Bound Shares ("<u>Proposed Value</u>"). If the Bound Shares are not the only assets subject to the Indirect Disposal by Change of Control, the price to be paid for the Bound Shares shall be determined based on the Fair Value of the Company, as set forth in <u>Clauses 7.8.7</u> through <u>7.8.14</u> below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.2 Within 120 (one hundred and twenty) days
from the sending of the Notice of Indirect Disposal by Change of Control, the notified Party shall have the right (and not the obligation):
a) to sell all (but not less than all) of its Shares to (i) the Third Party that has indirectly acquired the interest or (ii) the Party
that sent the Notice of Indirect Disposal, which shall be obligated to acquire them (" <u>Indirect Tag</u> ") or b) (i) to acquire
the Bound Shares held by the Party that sent the Notice of Indirect Disposal by Change of Control; or (ii) to designate a Third Party
to acquire the entirety of the Bound Shares on the same terms and conditions (" <u>Indirect Acquisition Right</u> ").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.3 The interest of the Party in exercising the
Indirect Tag or the Indirect Acquisition Right shall be formalized through the sending of a notice within the period set forth in <u>Clause 7.8.2</u> above (" <u>Indirect Tag Notice</u> " or " <u>Notice of Indirect Acquisition Right</u> "), which shall contain
a firm, irretractable and irrevocable statement to dispose of or acquire the Bound Shares of Braskem, as the case may be. The failure
to send the Indirect Tag Notice or the Notice of Indirect Acquisition Right within the period set forth in <u>Clause 7.8.2</u> shall be
deemed a waiver by the Party of the exercise of the respective rights. The same procedures applicable, *mutatis mutandis*, to the
Tag-Along Right, the Right of First Refusal, the Notice of Exercise of Tag-Along Right and the Decision Notice shall apply to the Indirect
Tag, the Indirect Acquisition Right, the Indirect Tag Notice and the Notice of Indirect Acquisition Right, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.4 If a Shareholder becomes aware of alleged
circumstances that, if true, constitute an Indirect Disposal by Change of Control with respect to the other Shareholder, and that such
change of Control has already occurred after 120 (one hundred and twenty) days without any Notice of Indirect Disposal by Change of Control
having been sent by the Shareholder subject to the indirect change of Control, the first Shareholder shall have the right to send a notice
to such other Shareholder, informing it of the facts demonstrating its knowledge of the Indirect Disposal by Change of Control (" <u>Notice of Knowledge of Indirect Disposal</u> "). The Shareholder notified pursuant to this <u>Clause 7.8.4</u> shall respond to such Notice
of Knowledge of Indirect Disposal within 15 (fifteen) Business Days after receipt, providing evidence with reasonable detail that no Indirect

Disposal has occurred, failing which the Indirect Disposal by Change of Control shall be deemed consummated and the sending, by it, of the Notice of Indirect Disposal by Change of Control referred to in <u>Clause 7.8</u> shall be presumed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.5 If the presumption of consummation of the
Indirect Disposal by Change of Control set forth in <u>Clause 7.8.4</u> applies with respect to one of the Parties, the other Party shall
have 15 (fifteen) Business Days, counted from the end of the period set forth in <u>Clause 7.8.4</u>, to send the Indirect Tag Notices
or the Notice of Indirect Acquisition Right, as the case may be, which shall meet the requirements set forth in <u>Clause 7.8.1</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.6 In the event of <u>Clause 7.8.5</u> above,
if the Indirect Tag or the Indirect Acquisition Right is exercised by one of the Parties, and the Bound Shares are not the only assets
subject to the Indirect Disposal by Change of Control, the price of the Bound Shares shall be the fair value of the Company, which shall
be determined as set forth in <u>Clauses 7.8.7</u> through <u>7.8.14</u> (" <u>Fair Value</u> "), in any case, considering the
interest that was indirectly disposed of.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.7 In the event that the Bound Shares are not
the only assets subject to the Indirect Disposal by Change of Control, the calculation of the Fair Value shall be obtained through a valuation
process to be conducted in accordance with the discounted cash flow method (" <u>DCF Method</u> "), for which, among other elements
customary in this type of exercise, the balance sheet of the Company to be prepared on the last day of the month preceding the date on
which the procedure begins, in accordance with Brazilian accounting rules and consistently with the practices adopted by the Company (" <u>Balance Sheet</u> "), shall be taken into account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.8 The DCF Method shall be based on projections
of the Company's cash flows and shall consider discount rates, assumptions, operating costs, investments, revenues and growth rates
that are reasonable and consistent with the Company's history, market participants, the sector and the industry, taking into consideration
the applicable risks, seasonal and economic cycles. To the extent that it deems it a relevant element for the DCF Method, any of the Parties
may request that the Balance Sheet be audited by the Company's external auditors, by notice to the Company within 5 (five) Business
Days of receipt of the Balance Sheet.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.9 The Fair Value shall be established by 2
(two) appraiser institutions, which shall be selected from among the 10 (ten) top-ranked in the "Oil & Gas" segment, with
global scope, according to historical information without time limitation (no date filter), extracted from the financial advisor M&A
ranking (league table), published by BLOOMBERG (" <u>Appraisers</u> "), one designated by Petrobras and

the other by the Fund, within 30 (thirty) days from the date on which the determination of the Fair Value is required or, if applicable, from the date of delivery of the audited Balance Sheet, should it be requested by one of the Shareholders. The Party that fails to designate the Appraiser within the period stipulated herein shall not have the right to make such selection *a posteriori* and shall be bound by the procedure established herein, with the Fair Value being that determined by the Appraiser selected by the other Shareholder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.10 The Parties shall cause the Fair Value to be determined by the Appraisers within 60 (sixty) days from
the end of the 30 (thirty)-day period mentioned above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.11 If the lower Fair Value determined by one of the Appraisers represents 90% (ninety percent) or more of
the Fair Value determined by the other Appraiser, the average of the two valuations shall constitute the final and binding Fair Value
between the Parties. If the lower Fair Value determined by one of the Appraisers represents less than 90% (ninety percent) of the Fair
Value determined by the other Appraiser and, if the Shareholders do not agree to adopt the average of the two valuations, a third Appraiser
shall be selected within 15 (fifteen) days. The third Appraiser shall be selected by drawing from among the 5 (five) top-ranked companies
in the "Energy" segment, with global scope, according to historical information without time limitation (no date filter),
extracted from the financial advisor M&A ranking (league table), published by BLOOMBERG, excluding the two Appraisers already selected.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.12 Once selected, the third Appraiser shall determine the fair market value within 60 (sixty) days from the
date on which it was selected. If the determination by the third Appraiser is carried out, the final and binding Fair Value shall be the
average of the 2 (two) Fair Value appraisals that are closest to each other in absolute terms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.13 The Parties agree that the determination of the Fair Value made in accordance with the provisions above
shall be final, binding and not subject to appeal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.8.14 The costs and fees of the Appraisers for the determination of the Fair Value and any audit of the Balance
Sheet shall be borne by the Party that requested them. If a third Appraiser is required, the costs and fees of such Appraiser shall be
divided between the Parties.

7.9 <u>Braskem's Cooperation</u>. The Shareholders agree that Braskem shall cooperate, where applicable, with the sale efforts of the Party interested in disposing of its interest to any Third Party, including in applicable cases of Permitted Transfers, and the managers (*administradores*) of Braskem shall participate in meetings or presentations directed at Third Parties interested in acquiring such shares, it being understood that

the expenses of such events or procedures shall be borne by the Shareholder that intends to dispose of its interest. In the event of an Indirect Disposal, the Parties agree that Braskem shall be obligated to provide and make available all documents and information necessary for the Company valuations established in <u>Clause 7.8</u>.

7.10 <u>Creation of Encumbrances</u>. With the exception of the Permitted Guarantees, the Parties are prohibited, with respect to their Bound Shares, from creating security interests, including, but not limited to, fiduciary assignment or pledge, as well as creating a usufruct over such Shares in favor of a Third Party, except as provided in this <u>Clause 7.10</u>. For the avoidance of doubt, (i) the restriction of <u>Clause 7.10</u> is applicable only and solely to the Shares, and does not extend to the securities issued by each Party and/or its Controllers or investors; (ii) in the event of enforcement of guarantees given by any of the Parties or their Controllers over their own securities, the provisions regarding the Right of First Refusal and/or Tag-Along Right of the Party shall be observed, including the consequences of Indirect Disposal by Change of Control, if applicable by their own terms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.10.1 The Parties (a " <u>Guarantor Party</u> ") may pledge as collateral, including through fiduciary
assignment, the proceeds from dividends and/or interest on equity, present and future, received from Braskem (" <u>Proceeds</u> "),
always proportionally to the Guarantor Party's direct participation, provided that such guarantee solely over the Proceeds does
not have any negative impact on the distribution of Proceeds to the Party that did not request the creation of such guarantee (" <u>Non-Guarantor Party</u> ").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.10.2 The Non-Guarantor Party shall be held harmless with respect to any and all Losses and Encumbrances of
any nature (including, but not limited to, taxes on any capital gains) or Third Party claims resulting from the enforcement of the guarantee
given by the Guarantor Party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.10.3 If, for any reason, an involuntary Encumbrance is created over all or part of the Bound Shares of a Party,
such Party agrees and hereby undertakes to use its best efforts to release such Shares from such Encumbrance within 15 (fifteen) days
from the date of awareness of the creation of such Encumbrance by the respective Party, notwithstanding the obligation to hold the other
Party harmless with respect to any and all Losses and Encumbrances as stipulated above.

7.11 <u>Right of First Refusal on the Disposal of Assets</u>. Subject to the applicable governance rules for the approval of asset disposals, if the Company decides to dispose of non-current assets or assets of its Subsidiaries that qualify as production units or business establishments, or shares and equity interests of Subsidiaries that carry out production activities, the Fund undertakes to exercise its voting rights within the Company so as to grant Petrobras a right of first refusal for the acquisition of such

assets, always respecting the rules and procedures of competitive processes and related party transactions to be established by the Board of Directors of the Company (and other applicable corporate bodies), pursuant to applicable Laws, including CVM regulations, as well as observing the principles and guidelines of <u>Clauses 2.2</u> and <u>Eight</u>.

7.12 <u>Unbinding</u>. For purposes of carrying out a Transfer as provided in <u>Clauses 7.4.3, 7.4.4</u> and <u>7.6.1(d)</u>, any of the Shareholders may unbind the Bound Shares owned by it from this Shareholders' Agreement ("<u>Unbinding</u>"). To this end, the Unbinding shall be effected by simple notice to the Share Registrar, such communication being sufficient for the Share Registrar to proceed with the Unbinding of such shares, without any need for additional consent from the other Parties or the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.12.1 Whenever necessary for the effectiveness of the Unbinding, the Company shall (and the Shareholders shall
cause the Company to): (a) adopt all measures reasonably requested to enable such Permitted Transfer, including making available to potential
investors, financial institution coordinators or any other Third Parties, after the execution of customary market-standard confidentiality
undertakings, the information and documents necessary for the structuring and execution of offerings conducted in a stock exchange or
organized over-the-counter market environment, whether through ordinary simple stock exchange transactions, through block trade or secondary
public offering of shares of the Company (follow-on); (b) ensure the participation of members of the management and key executives of
the Company in in-person or virtual meetings, conference calls, roadshows, due diligence sessions and other events typical of audit processes
conducted in transactions of this nature, provided that such activities follow customary market procedures and do not cause material harm
to the ordinary conduct of corporate business; and (c) carry out all actions mentioned in items (a) and (b) above in strict compliance
with applicable legislation and regulations, including rules issued by CVM, B3 and any other competent authorities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.12.2 The Bound Shares that are Unbound from this Agreement pursuant to this Clause shall be definitively Transferred
within 10 (ten) Business Days from the date of their Unbinding. During the period between the Unbinding of the Bound Shares for purposes
of Transfer and the effective consummation of the Transfer, the respective Shareholder shall fully comply with the provisions of this
Agreement, including with respect to the Bound Shares that are Unbound prior to the effective Transfer, with the Unbinding being permitted
exclusively for the purposes provided herein.
