If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of that series on such record date, or their duly appointed agent, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders, or their duly appointed agent, of the requisite principal amount of Outstanding Securities of that series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no further action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders, or their duly appointed agent, of the requisite principal amount of Outstanding Securities of that series on the date such action is taken.

Nothing in this paragraph

shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with further no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders, or their duly appointed agent, of the requisite principal amount of Outstanding Securities of that series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the expense of the Company, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of that series in the manner set forth in Section 1.06.

With respect to any record date set pursuant to this Section 1.04, the party hereto which sets such record date may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party or parties hereto in writing, and to each Holder of Securities of the applicable series in the manner set forth in Section 1.06, on or prior to the existing Expiration Date. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date and, if an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party or parties hereto that set such record date shall be deemed to have designated the 180th day after such record date as the Expiration Date with respect thereto.

(a) the Trustee by any Holder of Securities or by the Company shall, except as otherwise expressly provided herein, be deemed to have been received only upon actual receipt thereof by prepaid first class mail, courier or facsimile transmission, addressed to the Trustee at its Corporate Trust Office, Attention: Corporate Trust Services, or

(b) the Company or Braskem by the Trustee or by any Holder of Securities shall, except as otherwise expressly provided herein, be deemed to have been received

Section 1.06 Notice to Holders of Securities; Waiver. Unless otherwise herein expressly provided, where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given to Holders of Securities if in writing and mailed, first-class mail, postage prepaid, or delivered by hand or overnight courier to each Holder of a Security affected by such event, at its address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice; provided that notices to be given to Holders of Global Securities will be given to the Depositary, in accordance with its Applicable Procedures as in effect from time to time.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to Holders of Securities by mail, then such notification as shall be given with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In any case where notice to Holders of Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Security shall affect the sufficiency of such notice with respect to other Holders of Securities.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

The Trustee may rely upon and comply with instructions or directions sent via unsecured facsimile or email transmission and the Trustee shall not have any liability for any losses, liabilities, costs or expenses incurred or sustained by the Company, Braskem or the Holders due to the Trustee’s reliance upon and compliance with instructions or directions given by unsecured facsimile or email transmission; provided, however, that such losses have not arisen from the negligence or willful misconduct of the Trustee, it being understood that the failure of the Trustee to verify or confirm that the person delivering the unsecured facsimile or email transmission in which the instructions or direction, are contained is, in fact, authorized to deliver such unsecured facsimile or email transmission does not constitute negligence or willful misconduct.

Section 1.07 Language of Notices, Etc.. Any request, demand, authorization, direction, notice, consent, waiver or other action required or permitted under this Indenture shall be in the English language.

Section 1.08 Conflict with Trust Indenture Act.

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under the Trust

Indenture Act to be a part of and govern this Indenture, the provision of the Trust Indenture Act shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the provision of the Trust Indenture Act shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

Section 1.09 Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

Section 1.15 Appointment of Agent for Service; Submission to Jurisdiction; Waiver of Immunity. Each of the parties hereto hereby irrevocably submits to the non-exclusive jurisdiction of any New York state or U.S. federal court sitting in the Borough of Manhattan in The City of New York, with respect to actions brought against it as a defendant in respect of any suit, action or proceeding or arbitral award arising out of or relating to this Indenture, the Securities or any transaction contemplated hereby or thereby (a “Proceeding”), and irrevocably accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of the aforesaid courts. Each of the parties hereto irrevocably waives, to the fullest extent it may do so under applicable law, any objection which it may now or hereafter have to the laying of the venue of any such Proceeding brought in any such court and any claim that any such Proceeding

brought in any such court has been brought in an inconvenient forum. By the execution and delivery of this Indenture, each of the Company and Braskem irrevocably appoints National Corporate Research, Ltd. (the “Process Agent”), with an office at ▇▇ ▇▇▇▇ ▇▇^▇▇ ▇▇▇▇▇▇, ▇▇^▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, as its authorized agent to receive, on behalf of itself and its property, service of copies of the summons and complaint and any other process which may be served in any Proceeding brought in such New York state or U.S. federal court sitting in the Borough of Manhattan in The City of New York.

Failure of the Process Agent to give notice to the Company or Braskem, as the case may be, or failure of the Company or Braskem, as the case may be, to receive notice of such service of process shall not affect in any way the validity of such service on the Process Agent or the Company or Braskem. As an alternative method of service, each of the Company and Braskem also irrevocably consents to the service of any and all process in any such Proceeding by the delivery by hand of copies of such process to the Company or Braskem, as the case may be, at its address specified in the first paragraph of this Indenture or at any other address previously furnished in writing by the Company or Braskem to the Trustee. Each of the Company and Braskem covenants and agrees that it shall take any and all reasonable action, including the execution and filing of any and all documents, that may be necessary to continue the designation of the Process Agent above in full force and effect during the term of the Securities, and to cause the Process Agent to continue to act as such. If for any reason such Person shall cease to be such agent for service of process, the Company or Braskem, as the case may be, shall forthwith appoint a new agent of recognized standing for service of process in the State of New York and deliver to the Trustee a copy of the new agent’s acceptance of that appointment within 30 days. Nothing herein shall affect the right of the Trustee, any Paying Agent or any Holder to serve legal process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against the Company or Braskem, as the case may be, in any other court of competent jurisdiction. Each of the Company and Braskem irrevocably agrees that, in any proceedings anywhere (whether for an injunction, specific performance or otherwise), no immunity (to the extent that it may at any time exist, whether on the grounds of sovereignty or otherwise) from such proceedings, from attachment (whether in aid of execution, before judgment or otherwise) of its assets or from execution of judgment shall be claimed by it or on its behalf or with respect to its assets, except to the extent required by applicable law, any such immunity being irrevocably waived, to the fullest extent permitted by applicable law. Each of the Company and Braskem irrevocably agrees that, where permitted by applicable law, it and its assets are, and shall be, subject to such proceedings, attachment or execution in respect of its obligations under this Indenture and the Securities.

Section 1.16 Waiver of Jury Trial. EACH OF THE PARTIES HERETO AND EACH OTHER HOLDER OF A SECURITY BY ITS ACCEPTANCE THEREOF, HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING AMONG THE PARTIES HERETO ARISING OUT OF OR RELATING TO THIS INDENTURE, THE SECURITIES OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

Section 1.17 No Recourse Against Others.

By accepting a Security, each Holder shall waive and release all such liability. The waiver and release shall be part of the consideration for the issue of the Securities.

[Form of Reverse of Security]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more tranches of one or more series under an Indenture, dated as of December 16, 2013 (herein called the “Indenture”, which term shall have the meaning assigned to it in such instrument), among the Company, Braskem S.A., as Guarantor (herein called the “Guarantor”) and The Bank of New York Mellon, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Guarantor, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. The full and punctual payment of the principal of (and premium, if any, on) and interest on, and all other amounts payable under, this Security is guaranteed by the Guarantor. This Security is one of the series designated on the face hereof [if applicable, insert — , limited in aggregate principal amount to U.S.$[ ]].

[If applicable, insert — The Securities of this series are subject to redemption upon not less than [ ] days’ nor more than [ ] days’ notice, at any time [if applicable, insert — on or after [ ], 20[ ]], as a whole or in part, at the election of the Company, at the following Redemption Prices (expressed as percentages of the principal amount): If redeemed [if applicable, insert — on or before [ ], [ ]%, and if redeemed] during the 12-month period beginning [ ] of the years indicated,

and thereafter at a Redemption Price equal to [ ]% of the principal amount, together in the case of any such redemption with accrued interest to the Redemption Date, but interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture.]

[If the Security is subject to redemption of any kind, insert — In the event of redemption of this Security in part only, a new Security or Securities of this series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.]

[If the Security is not subject to redemption, insert — This Security is not redeemable prior to Stated Maturity.]

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security ,in each case upon compliance with certain conditions set forth in the Indenture.

[If the Security is not an Original Issue Discount Security, insert — If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.]

[If the Security is an Original Issue Discount Security, insert — If an Event of Default with respect to Securities of this series shall occur and be continuing, an amount of principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. Such amount shall be equal to — insert formula for determining the amount. Upon payment (i) of the amount of principal so declared due and payable and (ii) of interest on any overdue principal (and premium, if any) and interest (in each case to the extent that the payment of such interest shall be legally enforceable), all of the Company’s obligations in respect of the payment of the principal of (and premium, if any, on) and interest on the Securities of this series shall terminate.]

All payments by the Company and Braskem in respect of the Securities or the Guarantee, as the case may be, shall be made without withholding or deduction for or on account of, Brazilian Taxes or Austrian Taxes, unless such withholding or deduction is required by law. In that event, the Company or Braskem, as the case may be, shall pay to each Holder such Additional Amounts as may be necessary in order that every net payment made by the Company or Braskem, as the case may be, on each Security or the Guarantee after deduction or withholding for or on account of any Brazilian Taxes or Austrian Taxes shall not be less than the amount then due and payable on such Security.

The foregoing obligation to pay Additional Amounts shall not apply to or in respect of:

(i) any tax, assessment or other governmental charge which would not have been imposed but for the existence of any present or former connection between a Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of such Holder, if such Holder is an estate, a trust, a partnership or a corporation), on the one hand, and Brazil or Austria, on the other hand (including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member or shareholder) being or having been a citizen or resident thereof or having been engaged in a trade or business or present therein or having, or having had, a permanent establishment therein), other than the mere receipt of such payment or the ownership or holding of a Security or the Guarantee;

(ii) any tax, assessment or other governmental charge which would not have been so imposed but for the presentation by a Holder for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

(iii) any tax, duty, assessment or other governmental charge to the extent that such tax, duty, assessment or other governmental charge would not have been imposed but for the failure of a Holder or beneficial owner to comply with any certification, identification or other reporting requirements concerning the nationality, residence, identity or connection with Brazil or Austria of such Holder if (A) such compliance is required or imposed by law as a precondition to exemption from all or a part of such tax, duty, assessment or other governmental charge and (B) at least 30 days prior to the date on which the Company or Braskem, as the case may be, shall apply this Clause (iii), the Company or Braskem, as the case may be, shall have notified all Holders of Securities that some or all of the Holders of Securities shall be required to comply with such requirement;

(iv) any estate, inheritance, gift, sales, transfer, excise or personal property or similar tax, assessment or governmental charge;

(v) any withholding or deduction imposed on a payment to an individual and that is required to be made pursuant to any law implementing or complying with, or introduced in order to conform to, any European Union Directive on the taxation of savings;

(vi) any tax, assessment or other governmental charge which would have been avoided by such Holder presenting the relevant Security (if presentation is required) or requesting that such payment be made to another Paying Agent in a member state of the European Union;

(vii) any tax, assessment or other governmental charge which is payable other than by deduction or withholding from payments of principal of (and premium, if any, on) and interest on a Security; or

(viii) any combination of the above.

Notwithstanding anything to the contrary in the preceding paragraph, the Company, Braskem and any Paying Agent, the Trustee or any other Person shall be entitled to make any deduction or withholding, and shall not be required to pay any additional amounts with respect to any such deduction or withholding without any liability, imposed on or in respect of any Security pursuant to Section 1471 through Section 1474 of the Code (“FATCA”), any treaty, law, regulation or other official guidance enacted by any jurisdiction in which the Company or Braskem is organized, or in which payments on the Securities are made (each such jurisdiction, a “Taxing Jurisdiction”), implementing FATCA, or any agreement between the Company, Braskem, the Trustee or a Paying Agent and the United States, a Taxing Jurisdiction or any authority of any of the foregoing implementing FATCA.

The Company hereby covenants with the Trustee that it will promptly inform the Trustee if it determines in its reasonable discretion that any payment made by it is a payment which could be subject to FATCA withholding if a recipient of such payment had not complied with obligations imposed pursuant to Sections 1471 through 1474 of the Code and any regulations, or agreements thereunder or official interpretations thereof or any intergovernmental

agreement between the United States and another jurisdiction facilitating the implementation thereof or any law implementing such an intergovernmental agreement (including obligations to deliver proper documentation establishing the recipient’s status) at the time such payment was made.

The Company or Braskem, as the case may be, shall pay any present or future stamp, court or documentary taxes or any other excise or property taxes, charges or similar levies which arise in any jurisdiction from the execution, delivery, registration or the making of payments in respect of the Securities and the Guarantee, excluding any such taxes, charges or similar levies imposed by any jurisdiction outside of Brazil or Austria other than those resulting from, or required to be paid in connection with, the enforcement of the Securities and the Guarantee following the occurrence of any Default or Event of Default.

No Additional Amounts shall be paid with respect to a payment on any Security or the Guarantee to a Holder that is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent a beneficiary or settlor with respect to such fiduciary or a member of such partnership or beneficial owner would not have been entitled to receive payment of the Additional Amounts had the beneficiary, settlor, member or beneficial owner been the Holder of the Security or the Guarantee.

The Company or Braskem, as applicable, shall provide the Trustee with the official acknowledgment of the relevant taxing authority (or, if such acknowledgment is not available, other reasonable documentation) evidencing any payment of Brazilian Taxes or Austrian Taxes in respect of which the Company or Braskem has paid any Additional Amounts. Copies of such documentation shall be made available to the Holders of the Securities or the Paying Agents, as applicable, upon request therefor.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions (i) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of any series to be affected under the Indenture, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and (ii) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of any series to be affected under the Indenture, on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As set forth in, and subject to, the provisions of the Indenture, no Holder of any Security of this series will have any right to institute any proceeding with respect to the Indenture, this Security or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to the Securities

of this series, the Holders of not less than 25% in principal amount of the Outstanding Securities of this series shall have made written request, and offered indemnity or security satisfactory to the Trustee to institute such proceeding as trustee, and the Trustee shall not have received from the Holders of a majority in principal of the Outstanding Securities of this series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal (and premium, if any) or interest on this Security on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any, on) and interest on this Security at the times, Place of Payment and rate, and in the coin or currency, herein prescribed or to convert or exchange this Security as provided in the Indenture.

The Securities of this series are issuable only in registered form without coupons in denominations of U.S.$2,000 and any integral multiples of U.S.$1,000 thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company at any Place of Payment, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his or her attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Guarantor, the Trustee and any agent of the Company, the Guarantor or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Guarantor or the Trustee nor any such agent shall be affected by notice to the contrary.

The Indenture and the Securities shall be governed by and construed in accordance with the laws of the State of New York.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

more currencies or currency units other than that or those in which the Securities of that series are stated to be payable, the currency, currencies or currency units in which the principal of (and premium, if any, on) and interest on Securities of the applicable series as to which such election is made shall be payable, and the periods within which and the terms and conditions upon which such election is to be made and the amount so payable (or the manner in which such amount shall be determined);

(n) if other than the principal amount thereof, the portion of the principal amount of Securities of that series that shall be payable upon declaration of acceleration of the Maturity thereof pursuant to Section 5.02;

(o) if the principal amount payable at the Stated Maturity of any Securities of that series is not determinable as of one or more dates prior to the Stated Maturity, the amount that shall be deemed to be the principal amount of such Securities as of any such date for any other purpose hereunder, including the principal amount thereof that shall be due and payable upon any Maturity other than the Stated Maturity or that shall be deemed to be Outstanding as of any date (or, in any such case, the manner in which such principal amount shall be determined);

(p) that the Securities of that series shall be issuable in whole or in part in the form of one or more Global Securities, the respective Depositaries for such Global Securities, the form of any legend or legends that shall be borne by any such Global Securities in addition to or in lieu of that set forth in Section 2.03 and, if different from those set forth in Clause (iv) of the last paragraph of Section 3.04, any circumstances in which Securities issued upon any exchange may be registered in the name or names of Persons other than the Depositary for such Global Security or a nominee thereof;

(q) any addition to or change in the Events of Default that apply to any Securities of that series and any change in the right of the Trustee or the requisite Holders of such Securities to declare the principal amount thereof due and payable pursuant to Section 5.02;

(r) any addition to or change in the covenants set forth in Article X that applies to Securities of that series;

(s) whether and under what conditions additional Securities of that series may be created and issued;

(t) whether the Company or Braskem, as the case may be, shall pay to each Holder Additional Amounts (as defined in Section 10.08); and

(u) any other terms of the Securities of that series (which terms shall not be inconsistent with the provisions of this Indenture, except as permitted by Section 9.01(e)).

If any of the terms of the Securities of a series are established by action taken pursuant to an Authorization of the Company, a copy of an appropriate record of such action shall be certified by any Authorized Representative, and delivered to the Trustee at or prior to the delivery of the Officer’s Certificate setting forth the terms of that series.

Section 3.02 Denominations. Unless otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, any Securities of that series shall be issuable in minimum denominations of U.S.$2,000 and any integral multiple of U.S.$1,000 in excess thereof.

Section 3.03 Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by any two Authorized Representatives. The signature of any such Authorized Representative may be manual, facsimile or electronic (including “PDF” or similar files). Securities bearing the manual, facsimile or electronic signatures of individuals who were at any time a proper Authorized Representative shall bind the Company notwithstanding that such individuals or any of them have ceased to hold such positions prior to the authentication and delivery of such Securities or did not hold such positions on the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series, executed by the Company, to the Trustee for authentication, together with an Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Order shall authenticate and deliver such Securities.

If the forms or terms of the Securities of the applicable series have been established in or pursuant to one or more Authorizations as permitted by Sections 2.01 and 3.01, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be fully protected in relying upon, an Opinion of Counsel and Officers’ Certificate stating:

(a) that such forms or terms have been established in conformity with the provisions of this Indenture; and

(b) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute a valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to applicable bankruptcy, reorganization, insolvency, fraudulent transfer, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles (whether applied by a court of law or equity).

Notwithstanding the provisions of Section 3.01 and of the preceding paragraph, if all Securities of any series are not to be originally issued at one time, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 3.01 or the Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the time of authentication of each Security of that series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of that series to be issued.

Each Security shall be dated the date of its authentication.

The Trustee shall have the right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised in writing by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability based upon the written advice of counsel.

The Trustee shall not be required to authenticate the Securities of any series if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee.

The Company shall enter into any appropriate agency agreements with any Security Registrar, Transfer Agent or Paying Agent not a party to this Indenture, which shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Security Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 6.07. The Company initially appoints the Trustee as Security Registrar, Transfer Agent and Paying Agent.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.08, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

Section 3.04 Registration, Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers and exchanges of Securities as herein provided.

Except as otherwise provided in this Section 3.04(a), upon surrender for registration of transfer or exchange of a Security of any series at the office or agency in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like aggregate principal amount.

At the option of the Holder or in connection with partial redemptions undertaken pursuant to Article XI, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of a like aggregate principal amount upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to receive.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company evidencing the same debt and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his or her attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company and the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Sections 3.03, 9.06 or 11.07 not involving any transfer.

The Company shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before any selection of Securities of that series to be redeemed and ending at the close of business on the day of the mailing of the relevant notice of redemption or (ii) to register the transfer of or exchange any Security so selected for redemption, in whole or in part, except the unredeemed portion of any Security being redeemed in part.

The provisions of Clauses (i) through (v) below shall apply only to Global Securities:

(i) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary or Common Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture.

(ii) Subject to Clause (iv) below, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.

(iii) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Sections 3.04, 3.05, 9.06 or 11.07 or otherwise, shall be

authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.

(iv) Except as provided below, owners of beneficial interests in Global Securities will not be entitled to receive Securities registered in their names (“Certificated Securities”). Certificated Securities shall be issued to all owners of beneficial interests in a Global Security in exchange for such interests if:

A. The Depositary notifies the Company that it is unwilling or unable to continue as depositary for such Global Security or the Depositary ceases to be a clearing agency registered under the Exchange Act, at a time when such Depositary is required to be so registered in order to act as depositary, and in each case, and a successor depositary is not appointed by the Company within 90 days of such notice; or

B. An Event of Default has occurred and is continuing that results in any of the Securities of the applicable series becoming immediately due and payable.

In connection with the exchange of an entire Global Security for Certificated Securities pursuant to this Clause (iv), such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and upon receipt of an Order the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Certificated Securities of authorized denominations.

(v) Members of, or participants in, DTC or Euroclear and Clearstream, Luxembourg, as the case may be (“Agent Members”), shall have no rights under this Indenture with respect to any Global Security held on their behalf by DTC or by the Common Depositary under such Global Security, and DTC or the Common Depositary, as the case may be, may be treated by the Company, the Trustee, the Paying Agent and the Security Registrar and any of their agents as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, the Paying Agent or the Security Registrar or any of their agents from giving effect to any written certification, proxy or other authorization furnished by DTC or the Common Depositary or impair, as between DTC or Euroclear and Clearstream, Luxembourg and their respective Agent Members, the operation of customary practices governing the exercise of the rights of an owner of a beneficial interest in any Global Security. The registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Securities.

Section 3.05 Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like principal amount bearing a number not contemporaneously outstanding, appertaining to the surrendered Security.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to hold each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like principal amount bearing a number not contemporaneously outstanding.

Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and any such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 3.06 Payment of Interest; Interest Rights Preserved. Except as otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, interest on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid, in the case of Certificated Securities, to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest and, at the option of the Company, may be paid by check mailed to the address of the Person as it appears in the Security Register or, in the case of Global Securities, by wire transfer of same-day funds to the Holder.

Any interest on any Security of any series that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of that series (or their respective Predecessor

Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of that series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted interest as provided in this Clause (a). Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest, which shall be not more than 15 days and not less than ten days prior to the date of the proposed payment and not less than ten days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of that series in the manner set forth in Section 1.06, not less than ten days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of that series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (b).

(b) The Company may make payment of any Defaulted interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause (b), such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section 3.06 and Section 3.05, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such Predecessor Security.

Section 3.07 Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any, on) and (subject to Sections 3.04 and 3.06) interest on such Security, and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 3.08 Cancellation. All Securities surrendered for payment, redemption, or registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered

hereunder that the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section 3.08, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures unless otherwise directed by an Order.

Section 3.09 Computation of Interest. Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 3.10 CUSIP or ISIN Numbers. The Company in issuing the Securities may use “CUSIP” or “ISIN” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” or “ISIN” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP or ISIN numbers.

Section 3.11 Open Market Purchases. The Company, Braskem or any of their Affiliates may at any time purchase Securities in the open market or otherwise at any price. All Securities so purchased may not be resold, except in compliance with applicable requirements or exemptions under any relevant securities and other laws.

ARTICLE IV

Section 4.01 Satisfaction and Discharge of Indenture. This Indenture shall upon Order of the Company cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for, and any right to receive Additional Amounts as provided in Section 10.08), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when:

(a) either:

(i) all Securities theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.05 and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 10.06) have been delivered to the Trustee for cancellation; or

(B) will become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company,

and the Company in the case of Subclause (A), (B) or (C) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose money in an amount sufficient to pay and discharge the entire indebtedness on such Securities for principal (and premium, if any) and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 6.07, the obligations of the Company to any Authenticating Agent under Section 6.14 and, if money shall have been deposited with the Trustee pursuant to Subclause (B) of Clause (a)(i) of this Section 4.01, the obligations of the Trustee under Section 4.02 and the last paragraph of Section 10.07 shall survive.

Section 4.02 Application of Trust Money. Subject to the provisions of the last paragraph of Section 10.07, all money deposited with the Trustee pursuant to Section 4.01 shall be held in trust (without liability to the Holders for interest or investment) and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with or received by the Trustee.

ARTICLE V

Remedies

Section 5.01 Events of Default. “Event of Default,” wherever used herein with respect to the Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to, or as a result of any failure to obtain, any authorization, order, rule, regulation, judgment or decree of any governmental or administrative body or court):

(a) The Company or Braskem defaults in any payment of interest on any Securities of that series when the same becomes due and payable, and such Default continues for a period of 30 days;

(b) The Company or Braskem defaults in the payment of the principal (including premium, if any) of any Securities of that series when the same becomes due and payable upon its Stated Maturity, redemption or otherwise;

(c) The Company or Braskem fails to comply with any of its covenants or agreements in the Securities of that series or this Indenture (other than those referred to in Sections 5.01(a) and 5.01(b)) and such failure continues for 60 days after the Company or Braskem, as the case may be, receives a notice of Default from the Trustee or the Holders of at least 25% in principal amount of the Outstanding Securities of that series;

(d) Braskem or any Significant Subsidiary defaults under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Debt for money borrowed by Braskem or any such Significant Subsidiary (or the payment of which is guaranteed by Braskem or any such Significant Subsidiary) whether such Debt or guarantee now exists, or is created after the date of this Indenture, which default (1) is caused by failure to pay principal of (and premium, if any, on) or interest on such Debt after giving effect to any grace period provided in such Debt on the date of such default (“Payment Default”) or (2) results in the acceleration of such Debt prior to its express maturity and, in each case, the principal amount of any such Debt or guarantee, as applicable, together with the principal amount of any other such Debt or guarantee under which there has been a Payment Default or the maturity of which has been so accelerated, totals U.S.$150,000,000 (or the equivalent thereof at the time of determination) or more in the aggregate; provided that such Event of Default will be automatically rescinded or annulled if the Payment Default and/or the acceleration of Indebtedness is remedied or cured by Braskem or such Significant Subsidiary or waived by the Holders of such Debt within 60 days after the Payment Default and/or acceleration in respect of such Debt;

(e) One or more final judgments or decrees for the payment of money of U.S.$150,000,000 (or the equivalent in another currency at the time of determination, if applicable) or more in the aggregate are rendered against Braskem or any Significant Subsidiary and are not paid (whether in full or in installments in accordance with the terms of the judgment) or otherwise discharged (and otherwise not covered by an insurance policy or policies issued by reputable and creditworthy insurance companies) and, in the case of each such judgment or decree, either (a) an enforcement proceeding has been commenced by any creditor upon such judgment or decree and is not dismissed within 90 days following commencement of such enforcement proceedings or (b) there is a period of 90 days following such judgment during which such judgment or decree is not discharged, waived or the execution thereof stayed;

(f) Braskem pursuant to or within the meaning of any Bankruptcy Law:

(i) commences a voluntary case or files a request or petition for a writ of execution to initiate bankruptcy proceedings or have itself adjudicated as bankrupt;

(iii) applies for or consents to the appointment of a Custodian of it or for any substantial part of its property;

(iv) makes a general assignment for the benefit of its creditors;

(vi) grants a judicial or extrajudicial recovery to Braskem;

and, in the case of any of Subsection (g)(i) through (g)(vi), the order or decree remains unstayed and in effect for 45 days.

Section 5.02 Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in Sections 5.01(f) and 5.01(g)) occurs and is continuing, the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of any series may declare all unpaid principal of (and premium, if any, on) and accrued and unpaid interest on all Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee, if the notice is given by the Holders), stating that such notice is an “acceleration notice,” and upon any such declaration such amounts shall become due and payable immediately. If an Event of Default specified in Sections 5.01(f) and 5.01(g) occurs and is continuing, then the principal of (and premium, if any, on) and accrued and unpaid interest on all Securities of that series shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

At any time after a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article V, the Holders of a majority in principal amount of the Outstanding Securities of that series by written notice to the Company and the Trustee may rescind or annul such declaration if:

(i) the Company or Braskem has paid or deposited or caused to be paid or deposited with the Trustee a sum sufficient to pay (a) all overdue interest on Outstanding Securities of that series, (b) all unpaid principal of (and premium, if any, on) the Securities of that series that has become due other than by such declaration of acceleration, (c) to the extent that payment of such interest on the Securities of that series is lawful, interest on such overdue interest as provided herein and in the Securities of that series, and (d) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

(ii) all Events of Default have been cured or waived as provided in Section 5.13, other than the nonpayment of principal that has become due solely because of acceleration.

In the event of any Event of Default referred to in Sections 5.01(d)(1) and/or 5.01(d)(2), such Event of Default will be automatically rescinded or annulled if the Payment Default and/or the acceleration of the Debt referred to therein is remedied or cured by the Company, Braskem or such Significant Subsidiary or waived by the holders of such Debt within 60 days after the Payment Default and/or acceleration in respect of such Debt.

No such rescission or annulment referred to in either of the two preceding paragraphs of this Section 5.02 shall affect any subsequent Default or Event of Default or impair any right consequent thereto.

Section 5.03 Collection of Indebtedness and Suits for Enforcement by Trustee. If an Event of Default specified in Sections 5.01(a) or 5.01(b) occurs with respect to the Securities of any series, the Trustee, in its own name as trustee of an express trust, (i) may institute a judicial proceeding for the collection of the whole amount then due and payable on Securities of that series for principal (and premium, if any) and interest, and interest on any overdue principal (and premium, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installment of interest, at the rate borne by the Securities of that series, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, (ii) may prosecute such proceeding to judgment or final decree, and (iii) may enforce the same against the Company or any other obligor upon the Securities of that series and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Securities of that series, wherever situated.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of that series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

Section 5.04 Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Company or any other obligor upon the Securities of any series or the property of the Company or of such other obligor or their creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders of Securities of that series and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of Securities of that series to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of Securities of that series, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 6.07.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder of a Security in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders of Securities, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

Section 5.05 Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 6.07, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

Section 5.06 Application of Money Collected. Any money collected by the Trustee pursuant to this Article V shall be applied in the following order, on the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (and premium, if any) or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under Section 6.07;

SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any, on) and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest, respectively; and

THIRD: To the payment of the balance, if any, to the Company.

The Trustee may fix a record date for any payment to Holders of each applicable series of Securities pursuant to this Section 5.06. At least 10 days before such record date, the Trustee shall mail to each Holder of the applicable series of Securities and the Company a notice that states the record date, the payment date and amount to be paid.

Section 5.07 Limitation on Suits. No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, the Securities of the applicable series or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;

(b) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(c) such Holder or Holders have offered to the Trustee indemnity or security reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request;

(d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(e) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing itself of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders.

Section 5.08 Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any, on) and (subject to Section 3.06) interest on that Security on the respective Stated Maturity or Maturities expressed in that Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

Section 5.09 Restoration of Rights and Remedies. If the Trustee or any Holder of any Security has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, Braskem, the Trustee and the Holders of Securities shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 5.10 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.05, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 5.11 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article V or by law to the Trustee or to the Holders of Securities may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Securities, as the case may be.

Section 5.12 Control by Holders of Securities. The Holders of a majority in aggregate principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of that series, provided that:

(a) such direction shall not be in conflict with any rule of law or with this Indenture;

(b) the Trustee may take any other action deemed necessary by the Trustee that is not inconsistent with such direction; and

(c) the Trustee need not follow any such direction if doing so would in its reasonable discretion either involve it in personal liability or be unduly prejudicial to Holders of Securities of that series not joining in such direction.

Section 5.13 Waiver of Past Defaults. Subject to Section 5.02, the Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of that series waive in writing any past default hereunder with respect to Securities of that series and its consequences, except a default:

(a) in the payment of the principal of (and premium, if any, on) and interest on any Security of such series, or

(b) in respect of a covenant or provision hereof that under Article IX cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

The Holders of all Outstanding Securities of a series by written notice to the Trustee may waive any default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected. Upon any waiver described in this Section 5.13, such default shall cease to exist, and any Event of Default with respect to Securities of that series arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 5.14 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess reasonable costs, including reasonable attorney’s fees and expenses, against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section 5.14 nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or Braskem, in any suit instituted by the Trustee, in any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any series, or in any suit instituted by any Holder of any Security for the enforcement of the payment of the principal of (and premium, if any, on) or interest on any Security on or after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date).

Section 5.15 Waiver of Stay, Extension or Usury Laws. Each of the Company and Braskem covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture. Each of the Company and Braskem hereby expressly waives (to the extent that it may lawfully do so) all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE VI

The Trustee

Section 6.01 Certain Duties and Responsibilities. The duties, responsibilities, rights, benefits and protections of the Trustee shall be as specifically set forth in this Indenture and the Trust Indenture Act and no implied covenants or obligations shall be read into this Indenture against the Trustee, except as otherwise required by the Trust Indenture Act.

If an Event of Default has occurred and is continuing and a Responsible Officer has received written notification thereof, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate security or indemnity against such risk or liability is not assured to it. Whether or not herein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 6.01.

The Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it from the requisite amount of Holders or exercising any trust or power conferred upon the Trustee under this Indenture.

Section 6.02 Notice of Defaults. If the Trustee has actual written notice of an Event of Default with respect to Securities of any series, the Trustee shall give the Holders of Securities of that series notice of such Event of Default as and to the extent provided by the Trust Indenture Act; provided, however, that in the case of any default of the character specified in Section 5.01(c) with respect to Securities of that series, no such notice to such Holders shall be given until at least 60 days after the occurrence thereof.

Except in the case of a Default or Event of Defaults in payment of principal of our premium, if any, or interest on any Note, the Trustee may withhold the notice and shall be protected from withholding the notice if and so long as a committee of Responsible Officers of the Trustee in good faith determines that withholding the notice is in the interests of Holders.

Section 6.03 Certain Rights of Trustee. Subject to the provisions of Section 6.01:

(a) the Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon, other evidence of indebtedness or other paper or document (whether in its original or facsimile form) reasonably believed by it to be genuine and to have been signed or presented by the proper party or parties;

(b) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely and be fully protected for such reliance upon an Officer’s Certificate or an Opinion of Counsel;

(c) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for the willful misconduct or gross negligence on the part of any agent or attorney appointed with due care by it hereunder; provided that the Trustee shall be required to terminate any such agent if it has actual knowledge of any failure by such agent to perform its delegated duties as result of the negligence or willful misconduct of such agent as determined by a court of competent jurisdiction;

(d) any request or direction of the Company mentioned herein shall be sufficiently evidenced by an Order and any resolution of the Board of Directors of the Company or Braskem may be sufficiently evidenced by a Board Resolution;

(e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders of Securities of any series pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction;

(f) the Trustee shall not be liable for any action taken or omitted by it in good faith (including for errors in judgment) and believed by it to be within the discretion, rights or powers conferred upon it by this Indenture unless it was grossly negligent in ascertaining the pertinent facts or its conduct otherwise constitutes gross negligence;

(g) the Trustee may consult with counsel of its selection and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(h) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney (and the Company shall reimburse the Trustee for reasonable expenses in connection with such inquiry or investigation); provided that the Trustee shall not be entitled to such information which the Company is prevented from disclosing as a matter of law or contract;

(i) the Trustee shall not be required to invest, or shall be under any liability for interest, on any moneys at any time received by its pursuant to any of the provisions of this Indenture or the Securities except as the Trustee may otherwise agree with the Company. Such moneys need not be segregated from other funds except to the extent required by mandatory provisions of law;

(j) in no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever including but not limited to loss of profit irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action;

(k) the permissive rights of the Trustee enumerated herein shall not be construed as duties;

(l) the Trustee may request that the Company or Braskem deliver an Officer’s Certificate setting forth the names and/or titles of Officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any Officer authorized to sign an Officer’s Certificate, including any Officer specified as so authorized in any such certificate previously delivered and not superseded.

(m) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder;

(n) the Trustee shall not be deemed to have notice of any default (as defined in Section 6.02) or Event of Default unless a Responsible Officer of the Trustee has received written notice of any event which is in fact such a default at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; and

(o) the Trustee shall not be responsible for delays or failures in performance resulting from acts beyond its control. Such acts shall include but not be limited to acts of God, strikes, lockouts, riots, acts of war, epidemics, governmental regulations superimposed after the fact, fire, communication line failures, computer viruses, power failures, earthquakes, terrorist attacks or other disasters.

Section 6.04 Not Responsible for Recitals or Issuance of Securities. The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of the Securities or the proceeds thereof.

Section 6.05 May Hold Securities. The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company appointed hereunder, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 6.08 and 6.13, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

Section 6.06 Money Held in Trust. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on or investment of any money received by it hereunder except as otherwise agreed in writing with the Company.

Section 6.07 Compensation and Indemnity. Braskem and the Company, jointly and severally, agree to pay to the Trustee from time to time such compensation as shall be agreed upon in writing for its services. The Trustee’s compensation shall not be limited by any law regarding compensation of a trustee of an express trust. Braskem and the Company, jointly and severally, agree to reimburse promptly the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. Payments of any such expenses by Braskem or the Company to the Trustee shall be made free and clear of and without withholding or deduction for or on account of any Brazilian Taxes or Austrian Taxes, unless such withholding or deduction is required by law. In that event, Braskem or the Company shall pay to the Trustee such additional amounts as may be necessary in order that every net payment made by Braskem or the Company to the Trustee after deducting or withholding for or on account of any Brazilian Taxes or Austrian Taxes shall not be less than the amount then due and payable to the Trustee; provided, however, that the foregoing obligation to pay additional amounts shall not apply to or in respect of (i) any tax, assessment or other governmental charge which would not have been imposed but for the existence of any present or former connection between the Trustee, on the one hand, and Brazil or Austria, on the other hand, other than the mere receipt of payments of such expenses; (ii) any tax, duty, assessment or other governmental charge to the extent that such tax, duty, assessment or other governmental charge would not have been imposed but for the failure of the Trustee to comply with any certification, identification or other reporting requirements concerning the nationality, residence, identity or connection with Brazil or Austria of the Trustee if such compliance is required or imposed by law as a precondition to exemption from all or a part of such tax, duty, assessment or other governmental charge; (iii) any tax, assessment or other governmental charge which is payable other than by deduction or withholding from payments of any such expenses; or (iv) any combination of the above. The Company and Braskem, jointly and severally, shall indemnify each of the Trustee against any and all loss, liability or expense (including reasonable attorneys’ fees and expenses) incurred by it without gross negligence, bad faith or willful misconduct on its part arising out of and in connection with the administration of this Indenture and the performance of its respective duties hereunder, including the costs and expenses of defending itself against any claim or liability and of complying with any process served upon it or any of its officers in connection with the exercise or performance of any of its powers or duties under this Indenture. For the avoidance of doubt, the obligation in the preceding sentence to indemnify the Trustee shall not apply to or in respect of taxes incurred as a result of the receipt by the Trustee of compensation for their services. The Trustee shall notify the Company or Braskem, as the case may be, promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company or Braskem shall not relieve the Company or Braskem of its obligations hereunder. The Company or Braskem, as the case may be, shall defend the claim and the Trustee may have separate counsel and the Company or Braskem, as the case may be, shall pay the reasonable fees and expenses of such counsel.

To secure the payment obligations of the Company and Braskem in this Section 6.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of (and premium, if any, on) and interest on particular Securities.

The obligations of the Company and Braskem pursuant to this Section 6.07 shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default or Event of Default specified in Sections 5.01(f) and 5.01(g), the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

The Company and Braskem acknowledge that the Trustee make no representations as to the interpretation or characterization of the transactions herein undertaken for tax or any other purpose, in any jurisdiction. The Company and Braskem represent that they have fully satisfied themselves as to any tax impact of this Indenture before agreeing to the terms herein, and are responsible for any and all federal, state, local, income, franchise, withholding, value added, sales, use, transfer, stamp or other taxes imposed by any jurisdiction in respect of this Indenture.

Section 6.08 Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

For this purpose, the Trustee shall not be deemed to have a conflicting interest by reason of being Trustee for the Securities of any series and Trustee for the Securities of any other series.

Section 6.09 Corporate Trustee Required; Eligibility. There shall at all times be one and only one Trustee hereunder with respect to the Securities of each series, which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least U.S.$50,000,000 and its Corporate Trust Office in the Borough of Manhattan in The City of New York. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of the applicable supervising or examining authority, then for the purposes of this Section 6.09 and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section 6.09, it shall resign immediately in the manner and with the effect hereinafter specified in this Article VI.

Section 6.10 Resignation and Removal; Appointment of Successor. (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article VI shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.11.

(b) The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within

30 days after the giving of such notice of resignation, the resigning Trustee may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of that or those series.

(c) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of that series, delivered to the Trustee and to the Company. The Trustee so removed may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor Trustee if no successor Trustee has been appointed within 30 days of such removal.

(d) If at any time:

(i) the Trustee shall fail to comply with Section 6.08 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months; or

(ii) the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after written request therefor by the Company or by any such Holder; or

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (A) the Company may remove by Board Resolution the Trustee with respect to all Securities, or (B) subject to Section 5.14, any Holder of a Security who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company shall by Board Resolution promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 6.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of that series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.11, become the successor Trustee with respect to the Securities of that series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders of Securities of that series and accepted appointment in the manner required by Section 6.11, any Holder of a Security who has been a bona fide Holder of a Security of that

series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of that series.

(f) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of that series in the manner provided in Section 1.06. Each notice shall include the name of the successor Trustee with respect to the Securities of that series and the address of its Corporate Trust Office.

Section 6.11 Acceptance of Appointment by Successor. (a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to each of the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

(b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series of the Company, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series of the Company shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (i) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (ii) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (iii) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture, the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

(c) Upon request of any such successor Trustee, the Company shall execute any and all instruments necessary or desirable for more fully and certainly vesting in and confirming to such successor Trustee all rights, powers and trusts referred to in paragraph (a) and (b) of this Section 6.11, as the case may be.

(d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article VI.

Section 6.12 Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation shall be otherwise qualified and eligible under this Article VI, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

Section 6.13 Preferential Collection of Claims Against Company. The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship listed in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent indicated.

Section 6.14 Appointment of Authenticating Agent. The Trustee may appoint an Authenticating Agent or Agents with respect to Securities of one or more series which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon registration of transfer, exchange or partial redemption thereof or pursuant to Section 3.04, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee and a copy of which shall be promptly furnished to the Company. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than U.S.$50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of the applicable supervising or examining authority, then for the purposes of this Section 6.14, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 6.14, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section 6.14.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section 6.14, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 6.14, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 1.06 to all Holders of Securities of that series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section 6.14.

If an appointment with respect to Securities of one or more series is made pursuant to this Section 6.14, the Securities of that series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.


The Bank of New York Mellon, as Trustee

By:
		Authenticating Agent

By:
		Authorized Signatory

If all of the Securities of any series may not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of that series authenticated upon original issuance, the Trustee, if so requested by the Company in writing

(which writing need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel), shall appoint in accordance with this Section 6.14 an Authenticating Agent having an office in the Place of Payment designated by the Company with respect of Securities of that series.

Consolidation, Merger, Conveyance, Transfer or Lease

Section 8.01 Limitation on Consolidation, Merger, Sale or Conveyance. Braskem shall not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of its assets to, any Person, unless:

(a) the resulting, surviving or transferee Person (if not Braskem or any of its Subsidiaries) (the “Successor Guarantor”) shall expressly assume, by an indenture supplemental to this Indenture, executed and delivered to the Trustee, all the obligations of Braskem under this Indenture and the Securities, as applicable;

(b) the Successor Guarantor, if not organized and existing under the laws of Brazil, undertakes, in such supplemental indenture, to pay such Additional Amounts in respect of principal (and premium, if any) and interest as may be necessary in order that every net payment made in respect of the Guarantee after deduction or withholding for or on account of any present or future tax, penalty, fine, duty, assessment or other governmental charge imposed by such other country or any political subdivision or taxing authority thereof or therein shall not be less than the amount of principal (and premium, if any) and interest then due and payable on the Guarantee, subject to the same exceptions set forth under Sections 10.8(a) through (f), but replacing existing references in such clauses to Brazil and Austria with references to such other country; provided, however, that notwithstanding anything to the contrary in this paragraph, the Successor Guarantor shall be entitled to make any deduction or withholding, and shall not be required to pay any additional amounts with respect to any such deduction or withholding, imposed on or

in respect of any Security pursuant to Section 1471 through Section 1474 of the Code (“FATCA”), any treaty, law, regulation or other official guidance enacted by Austria, any jurisdiction in which the Successor Guarantor is organized or in which payments on the Securities are made (each such jurisdiction, a “Successor Guarantor Taxing Jurisdiction”), implementing FATCA, or any agreement between the Successor Guarantor, the Company or a paying agent and the United States, a Successor Guarantor Taxing Jurisdiction or any authority of any of the foregoing implementing FATCA.

Section 8.02 Successor Substituted. Upon any consolidation or merger, or any sale, assignment, conveyance, transfer, lease or disposition of all or substantially all of the properties and assets of Braskem in accordance with Section 8.01 in which Braskem is not the continuing obligor under this Indenture, the surviving or transferor Person shall succeed to, and be substituted for, and may exercise every right and power of, Braskem under this Indenture with the same effect as if such successor had been named as Braskem therein. When a successor assumes all the obligations of its predecessor under this Indenture and the Securities, the predecessor shall be released from those obligations; provided that in the case of a transfer by lease, the predecessor shall not be released from the payment of principal of (and premium, if any, on) and interest on the Securities.

Section 8.03 Securities to Be Secured in Certain Events. If, upon any such consolidation of Braskem with or merger of Braskem into any other corporation, or upon any conveyance, lease or transfer of the property of Braskem substantially as an entirety to any other Person, any property or assets of Braskem would thereupon become subject to any Lien, then unless such Lien could be created pursuant to Section 10.09 without equally and ratably securing the Securities, Braskem, prior to or simultaneously with such consolidation, merger, conveyance, lease or transfer, shall as to such property or assets, secure the Outstanding Securities (together with, if Braskem so determines, any other Debt of Braskem now existing or hereinafter created which is not subordinate in right of payment to the Securities) equally and ratably with or prior to the Debt which upon such consolidation, merger, conveyance, lease or transfer is to become secured as to such property or assets by such Lien, or shall cause such Securities to be so secured.

ARTICLE IX

(j) to make any other change that does not materially and adversely affect the rights of any Holder or Securities.

ARTICLE X

Covenants

Section 10.01 Payment of Principal, Premium and Interest. The Company covenants and agrees for the benefit of Holders of each series of Securities that it will duly and punctually pay the principal of (and premium, if any) and interest on the Securities of that series in accordance with the terms of the Securities of that series and this Indenture.

Section 10.02 Maintenance of Office or Agency. So long as the Securities of any series are Outstanding, the Company will maintain in the Borough of Manhattan in The City of New York, an office or agency where Securities may be presented or surrendered for payment where notices to and demands upon the Company in respect of this Indenture and the Securities of that series may be served, and the Company will not change the designation of such office without using commercially reasonably efforts to provide prior notice to the Trustee and designation of a replacement office in the same general location. The Corporate Trust Office of the Trustee shall be such office or agency of the Company, unless the Company shall designate and maintain some other office or agency for one or more of such purposes. If at any time the Company shall fail to maintain any required office or agency or shall fail to furnish the Trustee with the address thereof, all presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

Section 10.03 Maintenance of Corporate Existence. Braskem shall: (i) maintain in effect its corporate existence and all registrations necessary therefor; provided that these registrations shall not prohibit any transactions permitted by Article VIII or the merger of any Significant Subsidiary with or into Braskem or with or into any other Wholly-Owned Subsidiary of Braskem; (ii) take all reasonable actions to maintain all rights, privileges, titles to property, franchises and the like necessary or desirable in the normal conduct of their respective businesses, activities or operations; and (iii) maintain or cause to be maintained in good repair, working order and condition (normal wear and tear excepted) all properties used or useful in their business.

Section 10.04 Statement by Officers as to Default. Braskem will deliver to the Trustee, within 120 days after the end of each fiscal year of Braskem ending after the date hereof

(which, unless the Trustee is notified otherwise, shall be December 31), an Officer’s Certificate stating whether or not, to the knowledge of the Officer or Officers executing such Officer’s Certificate, an Event of Default in connection with the performance and observance of any of the terms, provisions and conditions of this Indenture exists and, if an Event of Default exists, setting forth the details thereof and the action which the Company or Braskem, as the case may be, is taking or proposes to take with respect thereto. Within five Business Days after any director or executive officer of the Company or Braskem, as the case may be, becomes aware of the existence of a Default or Event of Default, Braskem shall provide the Trustee with an Officer’s Certificate setting forth the details thereof and the action which the Company or Braskem, as the case may be, is taking or proposes to take with respect thereto.

Section 10.05 Provision of Financial Statements and Reports. The Company (unless at the time no Outstanding Securities have been registered with the Commission pursuant to the Securities Act) and Braskem shall file with the Trustee and the Commission, and transmit to Holders, such information, documents and other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant to the Trust Indenture Act. In the event that the Company or Braskem, as the case may be, files any financial statements or reports with the Commission or publishes or otherwise makes such statements or reports publicly available in Brazil, the United States or elsewhere, the Company or Braskem, as the case may be, will furnish a copy of the statements or reports to the Trustee within 15 calendar days of the date of filing or the date the information is published or otherwise made publicly available. For purposes of this Section 10.05, as long as the financial statements or reports are publicly available and accessible electronically by the Trustee, the filing or electronic publication of such financial statements or reports shall comply with the Company’s and Braskem’s respective obligations to deliver such statements and reports to the Trustee hereunder. The Company or Braskem, as the case may be, shall provide the Trustee with prompt written notification at such time that the Company or Braskem, as the case may be, becomes or ceases to be required to file information, documents or reports with the Commission pursuant to Section 13 or 15(d) of the Exchange Act. The Trustee shall have no obligation to determine if and when the Company’s or Braskem’s financial statements or reports are publicity available and accessible electronically. The above reports may be delivered by the Company to the Trustee in physical or electronic form, as determined by the Company.

Delivery of these reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of any of those will not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s and Braskem’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

Section 10.06 Payments and Paying Agents. The Company will, prior to 10:00 a.m., New York City time, on the Business Day preceding any date of payment of the principal of (or premium, if any) or interest on Securities of any series, deposit with the Trustee a sum sufficient to pay such principal (or premium, if any) or interest so due on that date of payment.

Whenever the Company shall appoint a Paying Agent other than the Trustee with respect to Securities of any series, it will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 10.06:

(a) that it will hold all sums received by it for the payment of the principal of (or premium, if any) or interest on any Securities (whether such sums have been paid to it by or on behalf of the Company or by any other obligor on the Securities) in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein;

(b) that it will give the Trustee notice of any failure by the Company (or by any other obligor on the Securities) to make any payment of the principal of (or premium, if any) or interest on, Securities of any series when the same shall be due and payable; and

(c) that it will pay any such sums so held in trust by it to the Trustee upon the Trustee’s written request at any time during the continuance of the failure referred to in Clause (b) above.

The Trustee shall arrange with all such Paying Agents for the payment, from funds furnished by the Company to the Trustee pursuant to this Indenture, of the principal of (and premium, if any, on) and interest due on, the Securities.

Whenever the Company shall have one or more Paying Agents (other than the Trustee) for the Securities of any series, it shall, on or before each due date of the principal of (or premium, if any) or interest on, the Securities of that series, deposit with such Paying Agents a sum sufficient to pay such principal (or premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal (or premium, if any) or interest, and the Company shall promptly notify the Trustee in writing of such action or any failure so to act.

If the Company shall at any time act as its own Paying Agent with respect to Securities of any series, it will, on or before each due date of the principal of (or premium, if any) or interest on, the Securities of that or those series, set aside, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay such principal (or premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided. The Company will promptly notify the Trustee of any failure so to act.

Anything in this Section 10.06 to the contrary notwithstanding, the Company may at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture with respect to Securities of any series, or for any other reason, pay or cause to be paid to the Trustee by any Paying Agent all sums held in trust with respect to Securities of that series by the Company or that Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or that Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

Anything in this Section 10.06, to the contrary notwithstanding, the agreements to hold sums in trust as provided in this Section are subject to the provisions of Section 4.02.

In the event that Braskem becomes obligated to make payments under Article XII, then Braskem shall make such payments in accordance with the foregoing provisions of this Section 10.06 to the fullest extent applicable.

Subject to applicable law, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (or premium, if any) or interest on, any Security and remaining unclaimed for two years after such principal (or premium, if any) or interest has become due and payable shall be paid to the Company or Braskem, as the case may be, at the written request of the Company or Braskem and subject to any relevant unclaimed property laws and regulations, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company or Braskem, as the case may be, for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall, upon written request and at the expense of the Company, cause to be published once, in a newspaper published in the English language, customarily published at least five days a week and of general circulation in the Borough of Manhattan in The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining shall be repaid to the Company.

Section 10.07 Waiver of Certain Covenants. Except as otherwise specified as contemplated by Section 3.01 for Securities of such series, the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 3.01(p), 9.01(a) or 9.01(e) for the benefit of the Holders of Securities of such series or any term, provision or condition set forth in an indenture supplemental hereto, if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. The Company shall provide the Trustee with written notification upon the waiver of any covenant.

Section 10.08 Additional Amounts. Unless otherwise specified in any Board Resolution of the Company or Braskem or indenture supplemental hereto establishing the terms of Securities of a series in accordance with Section 3.01, all payments by the Company and Braskem in respect of the Securities of each series or the Guarantee, as the case may be, shall be made without withholding or deduction for or on account of, Brazilian Taxes or Austrian Taxes, unless such withholding or deduction is required by law. In that event, the Company or Braskem, as the case may be, shall pay to each Holder such additional amounts (“Additional Amounts”) as may be necessary in order that every net payment made by the Company or Braskem, as the case

may be, on each Security of that series or the Guarantee after deduction or withholding for or on account of any Brazilian Taxes or Austrian Taxes shall not be less than the amount then due and payable on such Security. The foregoing obligation to pay Additional Amounts shall not apply to or in respect of:

(a) any tax, assessment or other governmental charge which would not have been imposed but for the existence of any present or former connection between a Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of such Holder, if such Holder is an estate, a trust, a partnership or a corporation), on the one hand, and Brazil or Austria, on the other hand (including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member or shareholder) being or having been a citizen or resident thereof or having been engaged in a trade or business or present therein or having, or having had, a permanent establishment therein), other than the mere receipt of such payment or the ownership or holding of a Security of that series or the Guarantee;

(b) any tax, assessment or other governmental charge that would not have been so imposed but for the presentation by a Holder for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

(c) any tax, duty, assessment or other governmental charge to the extent that such tax, duty, assessment or other governmental charge would not have been imposed but for the failure of a Holder or beneficial owner to comply with any certification, identification or other reporting requirements concerning the nationality, residence, identity or connection with Brazil or Austria of such Holder if (A) such compliance is required or imposed by law as a precondition to exemption from all or a part of such tax, duty, assessment or other governmental charge and (B) at least 30 days prior to the date on which the Company or Braskem, as the case may be, shall apply this Clause (c), the Company or Braskem, as the case may be, shall have notified all Holders of Securities of that series that some or all Holders of Securities of that series shall be required to comply with such requirement;

(d) any estate, inheritance, gift, sales, transfer, excise or personal property or similar tax, assessment or governmental charge;

(e) any withholding or deduction imposed on a payment to an individual and that is required to be made pursuant to any law implementing or complying with, or introduced in order to conform to, any European Union Directive on the taxation of savings;

(f) any tax, assessment or other governmental charge that would have been avoided by such Holder presenting the relevant Security (if presentation is required) or requesting that such payment be made to another Paying Agent in a member state of the European Union;

(g) any tax, assessment or other governmental charge that is payable other than by deduction or withholding from payments of principal of (or premium, if any) or interest on a Security of that series; or

(h) any combination of Clauses (a) through (g) above.

Notwithstanding anything to the contrary in the preceding paragraph, the Company, Braskem, the Trustee and any Paying Agent or any other Person shall be entitled to make any deduction or withholding, and shall not be required to pay any additional amounts with respect to any such deduction or withholding without any liability, imposed on or in respect of any Security pursuant to FATCA, any treaty, law, regulation or other official guidance enacted by any jurisdiction in which the Company or Braskem is organized, or in which payments on the Securities are made (each such jurisdiction, a “Taxing Jurisdiction”), implementing FATCA, or any agreement between the Company, Braskem, the Trustee or a Paying Agent and the United States, a Taxing Jurisdiction or any authority of any of the foregoing implementing FATCA.

The Company or Braskem, as the case may be, shall pay any present or future stamp, court or documentary taxes or any other excise or property taxes, charges or similar levies that arise in any jurisdiction from the execution, delivery, registration or the making of payments in respect of the Securities and the Guarantee, excluding any such taxes, charges or similar levies imposed by any jurisdiction outside of Brazil or Austria other than those resulting from, or required to be paid in connection with, the enforcement of the Securities and the Guarantee following the occurrence of any Default or Event of Default.

The Company or Braskem, as applicable, shall provide the Trustee with the official acknowledgment of the relevant taxing authority (or, if such acknowledgment is not available, other reasonable documentation) evidencing any payment of Brazilian Taxes or Austrian Taxes in respect of which the Company or Braskem has paid any Additional Amounts. Copies of such documentation shall be made available to the Holders of the Securities of the applicable series or the Paying Agents, as applicable, upon request therefor.

If the terms of the Securities of a series established as contemplated by Section 3.01 do not specify that Additional Amounts pursuant to the Section will not be payable by the Company or Braskem, the Company shall:

(a) at least 10 Business Days prior to the first Payment Date with respect to Securities of that series (and at least 10 Business Days prior to each succeeding Payment Date or any Redemption Date or Maturity Date with respect to Securities of that series if there has been any change with respect to the matters set forth in the below-mentioned Officer’s Certificate), deliver to the Trustee and each Paying Agent an Officer’s Certificate (A) specifying the amount,

if any, of taxes described in this Section 10.08 (the “Relevant Withholding Taxes”) required to be deducted or withheld on the payment of principal of (or premium, if any) or interest on, the Securities of that series to Holders and the Additional Amounts, if any, due to Holders in connection with such payment, and (B) certifying that the Company shall pay such deduction or withholding;

(b) prior to the due date for the payment thereof, pay any such Relevant Withholding Taxes, together with any penalties or interest applicable thereto;

(c) within 15 days after paying such Relevant Withholding Taxes, deliver to the Trustee and each Paying Agent evidence of such payment and of the remittance thereof to the relevant taxing or other authority as described in this Section 10.08; and

(d) pay any Additional Amounts due to Holders on any Interest Payment Date, Redemption Date or Maturity date to the Trustee in accordance with the provisions of this Section 10.08.

The Company and Braskem shall indemnify the Trustee and each Paying Agent for, and hold each harmless against, any loss, liability or expense reasonably incurred without gross negligence or willful misconduct on such Person’s part, arising out of or in connection with actions taken or omitted by any of them in reliance on any Officer’s Certificate furnished pursuant to this Section 10.08 or the failure of the Trustee or any Paying Agent for any reason (other than its own gross negligence or willful misconduct) to receive on a timely basis any such Officer’s Certificate or any information or documentation requested by it or otherwise required by applicable law or regulations to be obtained, furnished or filed in respect of such Relevant Withholding Taxes. The Company or Braskem, as the case may be, shall make available to any Holder requesting the same, evidence that the applicable Relevant Withholding Taxes have been paid.

Any Officer’s Certificate required by this Section 10.08 to be provided to the Trustee and each Paying Agent shall be deemed to be duly provided if sent by facsimile transmission to the Trustee and each Paying Agent.

Section 10.09 Limitation on Liens. Braskem shall not, and shall not permit any Significant Subsidiary to, create or suffer to exist any Lien upon any of its property or assets now owned or hereafter acquired by it or on any Capital Stock of any Significant Subsidiary securing any Debt of Braskem or any Significant Subsidiary unless contemporaneously therewith effective provision is made to secure the Securities equally and ratably with such obligation for so long as such obligation is so secured. The preceding sentence shall not require Braskem or any Subsidiary to equally and ratably secure the Securities if the Lien consists of a Permitted Lien.

Solely for purposes of this Section 10.09 (but not the definition of “Consolidated Total Assets”), and notwithstanding the definition of “Subsidiary,” a corporation, association, partnership or other business entity that constitutes a joint venture or similar entity between Braskem and/or one or more of its Subsidiaries, on the one hand, and one or more persons, on the other, and that would otherwise be a Subsidiary will not be deemed to be a Subsidiary (and,

therefore, not subject to this covenant); provided that such joint venture or similar entity is not fully consolidated in the financial statements of Braskem (and instead is proportionately consolidated under Brazilian Securities Commission Instruction No. 247, as amended, or any successor provision because it is jointly controlled by Braskem and/or its Subsidiaries, on the one hand, and such other persons, on the other); and provided further that the Debt secured or to be secured by Liens is incurred to finance the business of such joint venture or similar entity or property or assets owned or hereafter acquired, directly or indirectly, by it.

ARTICLE XI

Redemption of Securities

Section 11.01 Applicability of Article. Securities of any series that are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 3.01 for Securities of any series) in accordance with this Article XI.

Section 11.02 Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities of any series shall be evidenced by a Board Resolution. In case of any redemption of Securities at the election of the Company of Securities of any series, the Company shall notify the Trustee in writing of such Redemption Date and the aggregate principal amount of Securities of that or those series to be redeemed at least 20 days prior to the Redemption Date fixed by the Company (unless a shorter notice period shall be satisfactory to the Trustee), which notice shall be revocable at any time prior to the date on which the notice to the Holders referred to in Section 11.04 or Section 11.08 has been given. In the case of any redemption of Securities (i) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or (ii) pursuant to an election of the Company which is subject to a condition specified in the terms of the Securities, the Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance with such restriction.

Section 11.03 Selection by Trustee of Securities to Be Redeemed. If less than all Securities of any series are to be redeemed at any time, the selection of Securities of that series to be redeemed will be made by the Trustee in compliance with the requirements governing redemptions of the principal securities exchange, if any, on which Securities of that series are listed or if such securities exchange has no requirement governing redemption or the Securities of that series are not then listed on a securities exchange, on a pro rata basis or by lot (or, in the event that the Securities of that series are represented by Global Securities as of the Redemption Date, subject to the then-current rules and procedures of the applicable Depositary). If Securities of any series are redeemed in part, the remaining outstanding amount of any Security of that series must be at least equal to U.S.$2,000 and be an integral multiple of U.S.$1,000. The Trustee shall make the selection from the Outstanding Securities not previously called for redemption. The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount of the Securities to be redeemed. In the event of a partial redemption by lot, the Trustee shall select the particular Securities to be redeemed not less than five Business Days nor more than 60 days prior to the relevant Redemption Date from the Outstanding Securities of the applicable series not previously called for redemption.

The provisions of the preceding paragraph shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be at least equal to U.S.$2,000 and be an integral multiple of U.S.$1,000.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of those such Securities that has been or is to be redeemed.

Section 11.04 Notice of Redemption. Notice of redemption shall be given in the manner provided in Section 1.06 to each Holder of any Security to be redeemed (with a copy to the Trustee) not less than five Business Days nor more than 60 days prior to the Redemption Date. If the Securities to be redeemed are listed on any securities exchange, such notice shall also be made in compliance with the then current rules and procedures of such securities exchange.

All notices of redemption shall state:

(a) the Redemption Date;

(b) the Redemption Price, plus accrued interest and Additional Amounts, if any;

(c) the provision of this Indenture, any supplemental indenture or any applicable Security pursuant to which the Securities called for redemption are being redeemed;

(d) if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any Securities, the principal amounts) of the particular Securities to be redeemed and if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed;

(e) that on the Redemption Date the Redemption Price, plus accrued interest, if any, will become due and payable upon each such Security to be redeemed and, that, unless the Company defaults in making such redemption payment or any Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on the Securities called for redemption will cease to accrue on and after the Redemption Date;

(f) that Securities called for redemption must be surrendered to a Paying Agent to collect the Redemption Price, plus accrued interest and Additional Amounts, if any, and the place or places where each such Security is to be surrendered for payment of the Redemption Price, plus accrued interest and Additional Amounts, if any; and

(g) the CUSIP or ISIN number or numbers, if any, with respect to such Securities, and that no representation is made as to the correctness or accuracy of the CUSIP or ISIN number, if any, listed in such notice or printed on those Securities.

A notice of redemption published as contemplated by Section 1.06 need not identify particular Global Securities to be redeemed.

At the Company’s election and at its request, made in writing to the Trustee at least five Business Days before notice is to be mailed to the Holders, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided that the Company shall deliver to the Trustee, at least five Business Days prior to the date in which notice is to be mailed to the Holders, an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph; provided further that if the Company revokes the notice to the Trustee required by Section 11.02 in accordance with Section 11.02 prior to the Trustee’s delivering of notice to the Holders, the Trustee will not deliver such notice of redemption.

Section 11.05 Deposit of Redemption Price. Prior to 10:00 a.m., New York City time, on the Business Day preceding any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.06) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest and unpaid on, all the Securities which are to be redeemed on that date, other than Securities that have been delivered by the Company to the Trustee at least five Business Days prior to the Redemption Date for cancellation.

Section 11.06 Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified (together with accrued and unpaid interest, if any, to the Redemption Date), and from and after such date (except in the event of a default in the payment of the Redemption Price and accrued and unpaid interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with such notice, such Security shall be paid by the Company at the Redemption Price, together with accrued and unpaid interest to the Redemption Date; provided, however, that unless otherwise specified as contemplated by Section 3.01, installments of interest on Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.07.

If any Security called for redemption shall not be so paid upon surrender thereof in accordance with the Company’s instructions for redemption, the principal shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in that Security.

Section 11.07 Securities Redeemed in Part. Any Security that is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, in the case of Certificated Securities, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transference satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his or her attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

Section 11.08 Optional Redemption Due to Changes in Tax Treatment. (a) Securities of each series may be redeemed at the option of the Company, Braskem or any successor, in whole but not in part, at any time upon giving not less than five Business Days’ nor more than 60 days’ notice to the Holders (which notice shall be irrevocable) (except in the case of Securities that have a variable rate of interest, which may be redeemed on any Interest Payment Date) at a Redemption Price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon, to, but excluding, the Redemption Date, only if (i) the Company, Braskem or any successor has or will become obligated to pay Additional Amounts with respect to the Securities or the Guarantee (x) in excess of the Additional Amounts that the Company, Braskem or any successor would pay if payments in respect of the Securities or the Guarantee were subject to deduction or withholding for Brazilian Taxes at a rate of (A) 15% generally in case of any taxes imposed by Brazil or (B) 25% in case of taxes imposed by Brazil on amounts paid to residents of countries that do not impose any income tax or which impose it at a maximum rate lower than 20% or where the laws of that country or location impose restrictions on the disclosure of (1) shareholding composition; (2) the ownership of the investment; or (3) the beneficial ownership of income paid to non-resident persons, pursuant to Law No. 9,779, dated January 19, 1999, or (y) in respect of deduction or withholding for Austrian Taxes, in either case, as a result of any change in, or amendment to, the laws or regulations of Brazil or Austria (or the jurisdiction of any successor) or any political subdivision or governmental authority thereof or therein having power to tax, or any change in the application or official interpretation of such laws or regulations, which change or amendment occurs after the date of this Indenture (or date of succession) and (ii) such obligation cannot be avoided by the Company, Braskem or any successor taking reasonable measures available to it; provided, however, that for this purpose reasonable measures shall not include any change in the Company’s, Braskem’s or any successor’s jurisdiction of incorporation or organization or location of its principal executive office or registered office. No such notice of redemption shall be given earlier than 60 days prior to the earliest date on which the Company, Braskem or any successor, as the case may be, would be obligated to pay such Additional Amounts if a payment in respect of such Securities or the Guarantee were then due.

Prior to the publication or mailing of any notice of redemption pursuant to the preceding paragraph, the Company, Braskem or any successor shall deliver to the Trustee an Officer’s Certificate to the effect that the obligation of the Company, Braskem or any successor, as the case may be, to pay Additional Amounts cannot be avoided by the Company, Braskem or any successor taking reasonable measures available to it. The Company, Braskem or any successor, as the case may be, shall also deliver to the Trustee an Opinion of Counsel stating that the Company, Braskem or any successor, as the case may be, would be obligated to pay

Additional Amounts due to the changes in tax laws or regulations. The Trustee shall accept such Officer’s Certificate and Opinion of Counsel as sufficient evidence of the satisfaction of the conditions precedent set forth in Clauses (i) and (ii) of the preceding paragraph of this Section 11.08, in which event it shall be conclusive and binding on the Holders.

The Company or Braskem may enter into an arrangement under which Braskem or a subsidiary of Braskem may, in lieu of redemption by the Company or Braskem, purchase for a purchase price equal to the full Redemption Price any Security to be redeemed pursuant to this Section 11.08.

ARTICLE XII

Guarantee

Section 12.01 Unconditional Guarantee. Braskem hereby unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee, and to the Trustee on behalf of such Holder, the full and punctual payment of the principal of (and premium, if any, on) and interest on such Security when and as the same shall become due and payable, whether at Stated Maturity, upon declaration of acceleration, redemption or otherwise, in accordance with the terms of such Security and of this Indenture and all amounts payable by the Company under the Indenture (the “Guarantee”). In case of the failure of the Company punctually to make any such payment, Braskem hereby agrees to pay or cause such payment to be made punctually when and as the same shall become due and payable, whether at Stated Maturity, upon declaration of acceleration or redemption or otherwise, and as if such payment were made by the Company.

Braskem agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any exchange, or any release or amendment or waiver of any term of the Guarantee of all or any of the Securities, or any consent to departure from any requirement of the Guarantee of all or any of the Securities, the election by the Trustee or any of the Holders in any proceeding under any applicable Bankruptcy Law, the disallowance, under any applicable Bankruptcy Law, of all or any portion of the claims of the Trustee or any of the Holders for payment of any of the Securities (including any interest or Additional Amounts), any waiver or consent by the Holder of any Security or by the Trustee with respect to any provisions thereof or of this Indenture or with respect to the provisions of this Article XII as they apply to Braskem, the obtaining of any judgment against the Company or any action to enforce the same or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of Braskem. Braskem hereby waives the benefits of diligence, presentment, demand of payment, any requirement that the Trustee or any of the Holders protect, secure, perfect or insure any security interest in or other Lien on any property subject thereto or exhaust any right or take any action against the Company or any other Person, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to any Security or the Debt evidenced thereby and all demands whatsoever, and covenants that the Guarantee shall not be discharged in respect of any Security except by complete performance of the obligations contained in that Security and in the Guarantee. Braskem hereby agrees that, in the event of a Default in payment of principal (or

premium, if any) or interest on any Security, whether at Stated Maturity, upon declaration of acceleration, redemption or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of that Security, subject to the terms and conditions set forth in this Indenture, directly against Braskem to enforce the Guarantee without first proceeding against the Company. Braskem agrees if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the Stated Maturity of the Securities, to collect interest on the Securities, or to enforce or exercise any other right or remedy with respect to the Securities, to pay to the Trustee for the account of the Holders, upon demand thereof, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

Braskem hereby waives any benefits to which it is entitled under Articles 333, 827, 828, 834, 835, 838 and 839 of the Brazilian Civil Code, and Article 595 of the Brazilian Code of Civil Procedure.

The Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Securities is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by an obligee on the Securities whether as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance has not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Securities shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, restored or returned.

Rights of Holders to payment in full under the Securities pursuant to the Guarantee shall be equal in right of payment with all other existing and future senior unsecured obligations of Braskem, subject to certain statutory preferences under applicable law, and senior in right of payment to Braskem’s subordinated debt.

Section 12.02 Release of Braskem.

(a) Concurrently with any consolidation or merger of Braskem or conveyance, transfer or lease of all or substantially all of the assets of Braskem as permitted by Section 8.01, and upon delivery to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that such consolidation, merger, sale, conveyance or lease was made in accordance with Section 8.01, the Trustee shall execute any documents reasonably required in order to evidence the release of Braskem from its obligations under the Guarantee and under this Article XII.

(b) Concurrently with the legal defeasance or the covenant defeasance of the Securities under Section 14.01, Braskem shall be released from all of its obligations under the Guarantee and under this Article XII.

Section 12.03 Subrogation and Contribution

Upon making any payment with respect to any obligation of the Company under this Article XII, Braskem making such payment will be subrogated to the rights of the payee against the Company with respect to such obligation; provided, however, that Braskem shall not be entitled to enforce, or to receive any payments arising out of or based upon, such right of subrogation until the principal of (and premium, if any, on) and interest on all Securities of the applicable series shall have been paid in full.

ARTICLE XIII

Meetings of Holders of Securities

Section 13.01 Purposes for Which Meetings May Be Called. A meeting of Holders of Securities of any series may be called at any time and from time to time pursuant to this Article XIII to make, give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be made, given or taken by Holders of Securities of such series.

Section 13.02 Call, Notice and Place of Meetings. (a) The Trustee may at any time call a meeting of Holders of Securities of any series for any purpose specified in Section 13.01, to be held at such time and at such place in the Borough of Manhattan in The City of New York or elsewhere as the Trustee shall determine. Notice of every meeting of Holders, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such meeting, shall be given to the Company, Braskem and the Holders, in the manner provided in Section 1.06, not less than 10 nor more than 60 days prior to the date fixed for the meeting.

(c) Any meeting of Holders of Securities of any series shall be valid without notice if the Holders of all Outstanding Securities of that series are present in Person or by proxy, or if notice is waived before or after the meeting by the Holders of all Outstanding Securities of that series, and if the Company, Braskem and the Trustee are either present by duly authorized representatives or have, before or after the meeting, waived notice.

Section 13.03 Persons Entitled to Vote at Meetings. To be entitled to vote at any meeting of Holders of Securities of any series, a Person shall be (i) a Holder on a record date established pursuant to Section 1.04(c) of one or more Outstanding Securities of that series, or (ii) a Person appointed by an instrument in writing by a Holder or Holders of one or more Outstanding Securities of such series as proxy for such Holder or Holders. The only Persons who shall be entitled to be present or to speak at any meeting of Holders of Securities of any series shall be the Persons entitled to vote at such meeting and their counsel, any representatives of the Trustee and its counsel and any representatives of the Company or Braskem and their respective counsel.

Section 13.04 Quorum; Action. (a) The Persons entitled to vote a majority in principal amount of the Outstanding Securities of a series shall constitute a quorum for a meeting of Holders of Securities of that series.

(b) In the absence of a quorum within 15 minutes (and, at the discretion of the chairman of the meeting, a subsequent period of 15 minutes) of the time appointed for any meeting of Holders of Securities, the meeting shall, (1) if convened upon the request of Holders, be dissolved, or (2) if convened under any other circumstances, stand adjourned to the same day in the next week (or if such day is not a Business Day, the next succeeding Business Day) at the same time and place, subject and without prejudice to the transaction of the business (if any) for which a quorum is present.

(c) In the absence of a quorum at any meeting adjourned pursuant to Subsection (b) above and subsequently reconvened, the chairman of the meeting may either (with the approval of the Trustee) dissolve such meeting or adjourn the same for a period of not less than ten calendar days (but without any maximum number of calendar days) at such place as may be appointed by the chairman of the meeting either at or subsequent to such meeting.

(d) Notice of the reconvening of any adjourned meeting shall be given as provided in Section 13.02(a), except that such notice need be given only once not less than five days prior to the date on which the meeting is scheduled to be reconvened. Notice of a reconvening of an adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the Outstanding Securities of such series that shall constitute a quorum.

(e) Any resolution passed or decision taken at any meeting of Holders of Securities of any series duly held in accordance with this Section 13.04 shall be binding on all the Holders of Securities of that series, whether or not presented or represented at the meeting. However, for the avoidance of doubt, no actions taken at such meeting shall be binding on all Holders of Securities of that series unless such actions were approved by the minimum percentage in principal amount of the Outstanding Securities of that series as required elsewhere in this Indenture or under the Trust Indenture Act with respect to such actions.

Section 13.05 Determination of Voting Rights; Conduct and Adjournment of Meetings. (a) Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any action by or any meeting of Holders of Securities of any series in regard to proof of the holding of Securities of that series and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Such regulations may fix a record date and time for determining the Holders of record of Securities of that series entitled to vote at such meeting, in which case those and only those Persons who are Holders of Securities of that series at the record date and time so fixed, or their proxies, shall be entitled to vote at such meeting whether or not they shall be such Holders at the time of the meeting. Except as otherwise permitted or required by any such regulations, the holding of Securities shall be proved in the manner specified in Section 1.04 and the appointment of any proxy shall be proved in the manner specified in Section 1.04. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 1.04 or other proof.

(b) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company, Braskem or the Holders of Securities as provided in Section 13.02(b), in which case the Company, Braskem or the Holders of Securities of the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting and entitled to vote.

(c) At any meeting of Holders, each Holder of a Security of that series or proxy shall, subject to the provisions of Section 13.03, be entitled to one vote for each U.S.$1,000 principal amount of the Outstanding Securities of that series held or represented by him or her; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman may adjourn any such meeting if he or she is unable to determine whether any Holder or proxy shall be entitled to vote at such meeting. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or proxy.

(d) Any meeting of Holders of Securities of any series duly called pursuant to Section 13.02 at which a quorum is present may be adjourned from time to time by vote of the Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of that series represented at the meeting and entitled to vote, and the meeting may be held as so adjourned without further notice.

Section 13.06 Counting Votes and Recording Action of Meetings. The vote upon any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities of that series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of that series voted by the ballot. The permanent chairman of the meeting shall appoint two inspectors of votes, who shall count all votes cast at the meeting for or against any resolution and shall make and file with the secretary of the meeting their verified written

reports in duplicate of all votes cast at the meeting. A record, at least in duplicate, of the proceedings of each meeting of Holders of Securities of any series shall be prepared by the secretary of the meeting and there shall be attached to such record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts, setting forth a copy of the notice of the meeting and showing that such notice was given as provided in Section 13.02 and, if applicable, Section 13.04. Each copy of the record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company (with a copy to Braskem), and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

Defeasance and Covenant Defeasance

Section 14.01 Company’s Option to Effect Defeasance or Covenant Defeasance.

(a) Subject to Sections 4.01, 14.02 and 14.06, the Company and Braskem at any time may terminate (i) all their respective obligations under this Indenture and the Guarantee with respect to Securities of any series and the Securities of that series (“legal defeasance option”) or (ii) their respective obligations under Sections 8.01(c), 8.03, 10.03, 10.04, 10.05 and 10.09 and the operation of Sections 5.01(a) through (e) and Sections 5.01(f) and (g) with respect to any Significant Subsidiary, with respect to Securities of any series, and any covenants or Events of Default included in the supplemental indenture relating to the Securities of that series that are permitted to be terminated under the supplemental indenture relating to the Securities of that series (“covenant defeasance option”). The legal defeasance option with respect to Securities of any series may be exercised notwithstanding any prior exercise of the covenant defeasance option with respect to Securities of that series.

If the legal defeasance option is exercised with respect to Securities of any series, payment of the Securities of that series may not be accelerated because of an Event of Default with respect thereto. If the covenant defeasance option is exercised with respect to Securities of any series, payment of the Securities of that series may not be accelerated because of an Event of Default specified in Sections 5.01(a) through (e), Sections 5.01(f) and (g) with respect to any Significant Subsidiary, or any Events of Default included in the supplemental indenture relating to the Securities of that series that are permitted to be terminated under the supplemental indenture relating to the Securities of that series.

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of the obligations of the Company and Braskem hereunder with respect to the Securities of that series, except those specified in Section 14.01(b).

(b) Notwithstanding Section 14.01(a), the Company’s or Braskem’s obligations, as the case may be, with respect to Securities of any series pursuant to Sections 3.04, 3.05, 3.06, 6.07, 6.10, 7.01, 10.03, 10.06, 10.08, 14.04, 14.05 and 14.06 shall survive until the

Securities of that series have been paid in full. Thereafter, the obligations of the Company or Braskem, as the case may be, with respect to the Securities of that series pursuant to Sections 6.07, 6.10, 14.04 and 14.05 shall survive.

Section 14.02 Conditions to Defeasance. The Company or Braskem may exercise the legal defeasance option or the covenant defeasance option with respect to Securities of a series only if:

(a) The Company or Braskem irrevocably deposits or causes to be deposited with the Trustee as trust funds in trust, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of Securities of that series (the “defeasance trust”) pursuant to an irrevocable trust and security agreement in form and substance satisfactory to the Trustee, money or non-callable U.S. Government Obligations, or a combination thereof, sufficient for the payment of principal of (and premium, if any, on) and interest on all the Securities of that series to Maturity;

(b) The Company or Braskem delivers to the Trustee a certificate from an internationally recognized firm of independent accountants or investment bank expressing their opinion that the payments of principal of (and premium, if any, on) and interest on the Securities of that series when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment and after payment of all federal, state and local taxes or other charges or assessments in respect thereof payable by the Trustee shall provide cash at such times and in such amounts as shall be sufficient to pay principal of (and premium, if any, on) and interest on all the Securities of that series when due at Maturity;

(c) In the case of the legal defeasance option, 123 days pass after the deposit is made in accordance with the terms of Clause (a) and during such 123-day period no Default or Event of Default specified in Section 5.01(f) or (g) with respect to Braskem occurs that is continuing at the end of the period;

(d) No Default or Event of Default with respect to the Securities of that series has occurred and is continuing on the date of such deposit and after giving effect thereto;

(e) The deposit does not constitute a default or event of default under any other agreement binding on the Company or Braskem, as the case may be;

(f) The trust resulting from the deposit does not constitute, or is not qualified as, a regulated investment company under the Investment Company Act;

(g) Such legal defeasance or covenant defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of the Trust Indenture Act);

(h) In the case of the legal defeasance option, the Company or Braskem delivers to the Trustee an Opinion of Counsel stating that (i) the Company or Braskem, as the case may be, has received from, or there has been published by, the U.S. Internal Revenue Service a ruling, or (ii) since the date of this Indenture there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of

Counsel shall confirm that, the Holders of the Securities of that series shall not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and shall be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred;

(i) In the case of the covenant defeasance option, the Company or Braskem delivers to the Trustee an Opinion of Counsel to the effect that the Holders of the Securities of that series shall not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and shall be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and

(j) The Company or Braskem delivers to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities of that series as contemplated by this Article XIV have been complied with.

Before or after a deposit, the Company or Braskem may make arrangements satisfactory to the Trustee for the redemption of Securities of that series at a future date in accordance with Article XI and the supplemental indenture relating to the Securities of that series.

Section 14.03 Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to Section 14.02 and shall apply the deposited money and the money from U.S. Government Obligations through any Paying Agent in accordance with this Indenture and the provisions of the Securities of the series defeased to the payment of principal of (and premium, if any, on) and interest on the Securities of that series.

Section 14.04 Repayment to Company. Upon termination of the trust established pursuant to Section 14.02, the Trustee and each Paying Agent shall promptly pay to the Company or Braskem, as the case may be, upon request, any excess cash or U.S. Government Obligations held by them.

Subject to any applicable abandoned property law, the Trustee and each Paying Agent shall pay to the Company, upon request, any money held by them for the payment of principal of (or premium, if any) or interest on the Securities of the series defeased that remains unclaimed for two years after the due date for such payment of principal (or premium, if any) or interest, and, thereafter, the Trustee and each Paying Agent, as the case may be, shall not be liable for payment of such amounts hereunder and the Holders shall be entitled to such recovery of such amounts only from the Company.

Section 14.05 Indemnity for U.S. Governmental Obligations. The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations.

Section 14.06 Reinstatement. If the Trustee or any Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article XIV by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company or Braskem, as the case may be, under this Indenture and the Securities of the series defeased shall be revived and reinstated as though no deposit had occurred pursuant to this Article XIV until such time as the Trustee or such Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article XIV; provided, however, that, if the Company or Braskem, as the case may be, has made any payment of principal of (or premium, if any) or interest on any Securities of that series because of the reinstatement of its obligations, the Company or Braskem, as the case may be, shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or such Paying Agent.

ARTICLE XV

Substitution of the Company as Issuer

Section 15.01 Substitution of the Company as Issuer.

(a) Notwithstanding any other provision contained in this Indenture, the Company may, without the consent of any Holder (and by purchasing any Securities, each Holder expressly consents to the provisions of this Article XV), be substituted by (i) Braskem or (ii) any Wholly-Owned Subsidiary of Braskem as principal debtor (in such capacity, the “Substituted Issuer”) in respect of the Securities; provided that the following conditions are satisfied:

(i) such documents shall be executed by the Substituted Issuer, the Company, Braskem and the Trustee as may be necessary to give full effect to such substitution, including a supplemental indenture to this Indenture pursuant to which the Substituted Issuer assumes all of the Company’s obligations under this Indenture and the Securities (such documents collectively, the “Issuer Substitution Documents”) and (without limiting the generality of the foregoing) pursuant to which the Substituted Issuer shall undertake in favor of each Holder to be bound by the terms and conditions of the Securities and the provisions of this Indenture as fully as if the Substituted Issuer had been named in the Securities and this Indenture as the principal debtor in respect of the Securities in place of the Company and, unless Braskem is the Substituted Issuer or Braskem’s then-existing Guarantee remains in full force and effect following such substitution, Braskem shall unconditionally and irrevocably guarantee (the “Substitute Guarantee”) in favor of each Holder the payment of all sums payable by the Substituted Issuer as such principal debtor on the same terms mutatis mutandis as the Securities;

(ii) without limiting the generality of Section 15.01(a)(i), if the Substituted Issuer is organized in a jurisdiction other than the Austria, the Issuer Substitution Documents shall contain a covenant by the Substituted Issuer and/or such other provisions as may be necessary (1) to ensure that each Holder has the benefit of a covenant in terms corresponding to the obligations of the Company in respect of the

payment of Additional Amounts set forth in Section 10.08, with the substitution for the references to Austria of references to the jurisdiction in which the Substituted Issuer is organized (and with the substitution for the references to Austrian Taxes for references to taxes, duties, assessments, fees or other governmental charges imposed or levied by or on behalf of such jurisdiction or any political subdivision or authority thereof) and (2) to indemnify and hold harmless each Holder and beneficial owner of the Securities against all taxes or duties (i) that arise by reason of a law or regulation in effect or contemplated on the effective date of such substitution, which may be incurred or levied against such Holder or beneficial owner of the Securities as a result of any substitution pursuant to the conditions set forth in this Article XV and which would not have been so incurred or levied had such substitution not been made and (ii) that are imposed on such Holder or beneficial owner of the Securities by any political subdivision or taxing authority of any country in which such Holder or beneficial owner of the Securities resides or is subject to any such tax or duty and that would not have been so imposed had such substitution not been made, in each case subject to similar exceptions set forth under Section 10.08(a) through 10.08(h) mutatis mutandis; provided that any Holder making a claim with respect to such tax indemnity shall provide the Company with notice of such claim, along with supporting documentation, within four weeks of the announcement of the substitution of the Company as issuer; provided further, that notwithstanding anything to the contrary in this paragraph, the Substituted Issuer shall be entitled to make any deduction or withholding, and shall not be required to pay any additional amounts with respect to any such deduction or withholding, imposed on or in respect of any Security pursuant to FATCA, any treaty, law, regulation or other official guidance enacted by Brazil, any jurisdiction in which the Substituted Issuer is organized or in which payments on the Securities are made (each such jurisdiction, a “Substituted Issuer Taxing Jurisdiction”), implementing FATCA, or any agreement between the Substituted Issuer, Braskem or a paying agent and the United States, a Substituted Issuer Taxing Jurisdiction or any authority of any of the foregoing implementing FATCA.

(iii) the Company shall have delivered, or caused the delivery, to the Trustee an Opinion of Counsel addressed to the Company, the Substituted Issuer and the Trustee from an internationally recognized firm of counsel in the jurisdiction of organization of the Substituted Issuer, to the effect that the Issuer Substitution Documents and the Securities constitute valid and binding obligations of the Substituted Issuer, enforceable against the Substituted Issuer in accordance with their terms, subject to applicable bankruptcy, reorganization, insolvency, fraudulent transfer, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles (whether applied by a court of law or equity), such Opinion of Counsel to be dated not more than five days prior to the date of substitution of the Substituted Issuer for the Company;

(iv) the Company shall have delivered, or caused the delivery, to the Trustee of an Opinion of Counsel addressed to the Company, the Substituted Issuer and the Trustee from an internationally recognized firm of U.S. counsel, to the effect that (A) the Issuer Substitution Documents (including the Substitute Guarantee or the Guarantee of Braskem, as applicable) constitute valid and binding obligations of the parties thereto under the law of the State of New York, enforceable against such parties in accordance

with their terms, subject to applicable bankruptcy, reorganization, insolvency, fraudulent transfer, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles (whether applied by a court of law or equity), and (B) no consent, approval, authorization or order of any U.S. federal or New York State court or governmental agency or regulatory body is required for the consummation of the transactions contemplated by the Issuer Substitution Documents (including the Substitute Guarantee or the Guarantee of Braskem, as applicable) and compliance with the terms thereof by each of the Substituted Issuer, the Company and Braskem, except as may be required by U.S. state securities laws, such Opinion of Counsel to be dated not more than five days prior to the date of substitution of the Substituted Issuer for the Company;

(v) the Substituted Issuer shall have appointed a process agent in the Borough of Manhattan in The City of New York to receive service of process on its behalf in relation to any legal action or proceedings arising out of or in connection with the Securities, the Indenture and the Issuer Substitution Documents, which appointment shall be consistent with the appointment by the Company of the Process Agent set forth in Section 1.15;

(vi) no Event of Default shall have occurred or be continuing; and

(vii) such substitution shall comply with all applicable requirements under the laws of the jurisdiction of organization of the Substitute Issuer, Austria and Brazil.

(b) Upon compliance with the provisions of this Article XV and effectiveness of such substitution, the Substituted Issuer and the Company shall deliver to the Trustee an Officer’s Certificate certifying that the terms of this Article XV have been complied with and attaching copies of all documents referenced in or contemplated by this Article XV.

(c) Upon the execution of the Issuer Substitution Documents and the Substitute Guarantee, if applicable, and compliance with the other conditions set forth in Section 15.01(a), the Substituted Issuer shall be deemed to be named in the Securities as the principal debtor in place of the Company and the Securities shall thereupon be deemed to be amended to give effect to such substitution, the Company will be released from all of its obligations in respect of the Securities and this Indenture, including, without limitation, compliance with the covenants contained in Section 10.08, and, in the event that Braskem is the Substituted Issuer, Section 10.08 shall not apply to the Substituted Issuer.

(d) The Issuer Substitution Documents shall be delivered to and held by the Trustee for so long as any Security remains outstanding and for so long as any claim may be made against the Substituted Issuer or the Company by any Holder in respect of the Securities or the Issuer Substitution Documents shall not have been finally adjudicated, settled or discharged. The Substituted Issuer and the Company shall acknowledge in the Issuer Substitution Documents the right of every Holder to the production of the Issuer Substitution Documents for the enforcement of any of the Securities, the Indenture or the Issuer Substitution Documents.

(e) Not later than 10 Business Days after the execution of the Issuer Substitution Documents, the Substituted Issuer shall give notice thereof to the Holders in accordance with Section 1.06.

Notwithstanding any other provision of this Indenture, Braskem shall (unless it is the Substituted Issuer) do or cause to be done all acts and things and promptly execute and deliver any documents or instruments, including a Substitute Guarantee and a legal opinion of internationally recognized Brazilian counsel, that may be required, or that the Trustee may reasonably request, to ensure that the Guarantee or the Substitute Guarantee, as applicable, shall continue in full force and effect for the benefit of the Holders and beneficial owners of the Securities following the substitution pursuant to this Article XV.
