Braskem SA (BRD) Risk Analysis

As permitted by the Brazilian Corporate Law, our by-laws specify that 25% of our adjusted net profit for each fiscal year must be distributed to shareholders as mandatory dividends, or the Mandatory Distribution of Dividends. Under our by-laws, our class A and class B preferred shareholders are entitled to an annual non-cumulative preferential dividend, or the Minimum Preferred Dividend, equal to 6% of their pro rata share of our capital before dividends may be paid to our common shareholders. The Brazilian Corporate Law allows a publicly traded company like ours to suspend the Mandatory Distribution of Dividends in any particular year if our board of directors informs our shareholders that such distributions would be inadvisable in view of our financial condition or cash availability, provided that such suspension does not affect the Minimum Preferred Dividend, which is still payable to the holders of preferred shares. However, the shareholders, including the holders of our class A preferred shares or the ADSs, may not receive any dividends or interest on shareholders' equity in any given year if we do not record a profit.

Under the Brazilian Corporate Law and our by-laws, holders of our class A preferred shares and, consequently, the ADSs underlying these shares are not entitled to vote at meetings of our shareholders, except in very limited circumstances. These limited circumstances directly relate to key rights of the holders of class A preferred shares, such as modifying basic terms of our class A preferred shares or creating a new class of preferred shares with superior rights. Holders of preferred shares without voting rights are entitled to elect one member and his or her respective alternate to our board of directors and our fiscal council, depending on specific requirements provided in the Brazilian Corporate Law. Holders of our class A preferred shares and the ADSs are not entitled to vote to approve corporate transactions, including mergers or consolidations of our Company with other companies, or the declaration of dividends. However, if we do not pay dividends for three consecutive years, holders of our class A preferred shares and the ADSs will be granted voting rights. See "Item 10. Additional Information-Description of Our By-laws-Voting Rights."

Under Brazilian law, only shareholders registered as such in our corporate books may attend our shareholders' meetings. All class A preferred shares underlying the ADSs are registered in the name of the depositary. ADS holders may exercise the limited voting rights with respect to our class A preferred shares represented by the ADSs only in accordance with the deposit agreement relating to the ADSs, which provides that voting rights are only available to ADS holders at our discretion. There are practical limitations upon the ability of ADS holders to exercise their voting rights due to the additional steps involved in communicating with ADS holders. For example, we are required to publish a notice of our shareholders' meetings in certain newspapers in Brazil. To the extent that holders of our class A preferred shares are entitled to vote at a shareholders' meeting, they will be able to exercise their voting rights by attending the meeting in person, voting by proxy or by remote voting, if applicable. By contrast, holders of the ADSs will receive notice of a shareholders' meeting by mail from the depositary following our notice to the ADS depository requesting the ADS depository to do so. To exercise their voting rights, ADS holders must instruct the depositary on a timely basis. This noticed voting process will take longer for ADS holders than for holders of class A preferred shares. If it fails to receive timely voting instructions for all or part of the ADSs, the depositary will assume that the holders of those ADSs are instructing it to give a discretionary proxy to a person designated by us to vote their ADSs, except in limited circumstances. In the limited circumstances in which holders of the ADSs have voting rights, they may not receive the voting materials in time to instruct the depositary to vote the class A preferred shares underlying their ADSs. In addition, the depositary and its agents are not responsible for failing to carry out the voting instructions of the holders of the ADSs or for the manner of carrying out those voting instructions. Accordingly, holders of the ADSs may not be able to exercise their voting rights, and they will have no recourse if the class A preferred shares underlying their ADSs are not voted as requested.

The Brazilian custodian for the preferred shares underlying the ADSs must obtain an electronic registration number with the Central Bank to allow the depositary to remit U.S. dollars abroad. ADS holders benefit from the electronic certificate of foreign capital registration from the Central Bank obtained by the custodian for the depositary, which permits it to convert dividends and other distributions with respect to the class A preferred shares into U.S. dollars and remit the proceeds of such conversion abroad. If holders of the ADSs decide to exchange them for the underlying preferred shares, they will only be entitled to rely on the custodian's certificate of registration with the Central Bank for five business days after the date of the exchange. Thereafter, they will be unable to remit U.S. dollars abroad unless they obtain a new electronic certificate of foreign capital registration in connection with the preferred shares, which may result in expenses and may cause delays in receiving distributions. See "Item 10. Additional Information-Exchange Controls." Also, if holders of the ADSs that exchange the ADSs for our Class A preferred shares do not qualify under the foreign investment regulations, they will generally be subject to less favorable tax treatment of dividends and distribution on, and the proceeds from any sale of, our preferred shares. See "Item 10. Additional information-Exchange Controls" and "Item 10. Additional Information-Taxation-Brazilian Tax Considerations."

Holders of the ADSs are not our direct shareholders and are unable to enforce the rights of shareholders under our by-laws and the Brazilian Corporate Law. Our corporate affairs are governed by our by-laws and the Brazilian Corporate Law, which differ from the legal principles that would apply if we were incorporated in a jurisdiction in the United States, such as the State of Delaware or New York, or elsewhere outside Brazil. Even if a holder of ADSs surrenders its ADSs and becomes a direct shareholder, its rights as a holder of the class A preferred shares underlying the ADSs under the Brazilian Corporate Law to protect its interests relative to actions by our board of directors may be fewer and less well-defined than under the laws of those other jurisdictions. Although insider trading and price manipulation are crimes under Brazilian law and are the subject of continuously evolving regulations promulgated by the Brazilian Securities Commission, or the CVM, the Brazilian securities markets are not as highly regulated and supervised as the U.S. securities markets or the markets in some other jurisdictions. In addition, rules and policies against self-dealing or for preserving shareholder interests may be less well-defined and enforced in Brazil than in the United States and certain other countries, which may put holders of our class A preferred shares and the ADSs at a potential disadvantage when compared to holders of shares of companies incorporated in other jurisdictions. Corporate disclosures also may be less complete or informative than for a public company in the United States or in certain other countries.

We are a corporation (sociedade por ações) organized under the laws of Brazil, and all of our directors and executive officers and our independent public accountants reside or are based in Brazil. Most of our assets and those of these other persons are located in Brazil. As a result, it may not be possible for holders of the ADSs to effect service of process upon us or these other persons within the United States or other jurisdictions outside Brazil or to enforce against us or these other persons judgments obtained in the United States or other jurisdictions outside Brazil. In addition, because a substantial portion of our assets and all of our directors and officers reside outside the United States, any judgment obtained in the United States against us or any of our directors or officers may not be collectible within the United States. Because judgments of U.S. courts for civil liabilities based upon the U.S. federal securities laws may only be enforced in Brazil if certain conditions are met, holders may face greater difficulties in protecting their interests in the case of actions by us or our directors or executive officers than would shareholders of a U.S. corporation.

Sales of a substantial number of our class A preferred shares could negatively affect the market prices of our class A preferred shares and the ADSs. If substantial sales of shares are made through the securities markets by our controlling shareholders or other class A preferred shares, the market price of our class A preferred shares and, by extension, the ADSs may decrease significantly. As a result, holders of the ADSs may not be able to sell the ADSs at or above the price they paid for them.

Under Brazilian law, if we issue new shares in exchange for cash or assets as part of a capital increase, subject to certain exceptions, we must grant our shareholders preemptive rights at the time of the subscription of shares, corresponding to their respective interest in our share capital, allowing them to maintain their existing shareholding percentage. We may not legally be permitted to allow holders of ADSs or class A preferred shares in the United States to exercise any preemptive rights in any future capital increase unless (1) we file a registration statement for an offering of shares resulting from the capital increase with the U.S. Securities and Exchange Commission, or the SEC, or (2) the offering of shares resulting from the capital increase qualifies for an exemption from the registration requirements of the Securities Act. At the time of any future capital increase, we will evaluate the costs and potential liabilities associated with filing a registration statement for an offering of shares with the SEC and any other factors that we consider important in determining whether to file such a registration statement. We cannot assure the holders of the ADSs or class A preferred shares in the United States that we will file a registration statement with the SEC to allow them to participate in any of our capital increases. As a result, the equity interest of such holders into us may be diluted.

The Brazilian securities markets are substantially smaller, less liquid and more volatile than major securities markets in the United States and other jurisdictions, and may be regulated differently from the manner in which U.S. investors are accustomed. Factors that may specifically affect the Brazilian equity markets may limit the ability of holders of the ADSs to sell class A preferred shares underlying ADSs at a price and at a time when they wish to do so and, as a result, could negatively impact the market price of the ADSs themselves.

Novonor, directly or through its wholly-owned subsidiary OSP Investimentos S.A., or OSP Inv., owns 38.32 % of our total share capital, including 50.11% of our voting share capital, and Petrobras holds 36.14% of our total share capital, including 47.03% of our voting share capital. Nominees of Novonor constitute a majority of the members of our board of directors. Under a shareholders' agreement to which Novonor and Petrobras are parties, which we refer to as the Braskem S.A. Shareholders' Agreement, we may only undertake certain actions after Novonor and Petrobras have reached a consensus with respect to those actions. However, Novonor will have the sole power to approve our business plan, through the board of directors, as described under "Item 7. Major Shareholders and Related Party Transactions-Major Shareholders-Shareholders' Agreements." As a result, Novonor has the ability to determine the outcome of most corporate actions or decisions requiring the approval of our shareholders or our board of directors-in certain instances, with the consent of Petrobras-which could affect the holders of our class A preferred shares and of our American Depositary Shares, or ADSs. Furthermore, on June 17, 2019, Novonor, together with certain of its controlling and controlled entities, filed a petition for judicial restructuring before the First Judicial Bankruptcy Court of the State of São Paulo, Brazil, seeking a voluntary judicial restructuring and emergency relief staying certain foreclosure actions by their creditors (the "Novonor Judicial Restructuring Proceedings"). The Novonor Judicial Restructuring Proceedings does not include us. Although we are not currently a party to any pending bankruptcy or other judicial restructuring proceedings in Brazil or elsewhere, we are exposed to certain risks related to the Novonor Judicial Restructuring Proceedings, such as risks related to the change of our corporate control resulting from decisions taken and/or agreed under such proceedings and the consequences derived thereto, including but not limited to significant changes in our management and our strategy that may be undertaken by any new controlling shareholders that may arise from the conclusion of these proceedings. We have no control over the Novonor Judicial Restructuring Proceedings, and no assurance can be given on the outcome of the Novonor Judicial Restructuring Proceedings or their effect on us.
