(kk) None of the Company and any of its Subsidiaries or, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any of its Subsidiaries is currently subject to any U.S. sanctions administered by the OFAC; and the Company will not directly or indirectly use the proceeds of the offering of the Securities hereunder, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

(ll) The Securities will constitute direct, unconditional, senior and unsecured obligations, without any preference among themselves, of the Company and will rank pari passu with all other existing and future senior and unsecured obligations of the Company, subject to Enforceability Exceptions, except that certain claims against the Company, such as claims for salaries, wages, social security, taxes and other statutorily preferred claims, will have preference over any other claims; and the Securities constitute “senior indebtedness” as such term is defined in any indenture or agreement governing any outstanding subordinated indebtedness of the Company.

(mm) Except for AEL Sistemas S.A., no subsidiary of the Company is currently prohibited, directly or indirectly, under any agreement or other instrument to which it is a party or is subject, from paying any dividends to the Company, from making any other distribution on such subsidiary’s capital stock, from repaying to the Company any loans or advances to such subsidiary from the Company or from transferring any of such subsidiary’s properties or assets to the Company or any other subsidiary of the Company.

(nn) None of the Company and any of its Subsidiaries is a party to any contract, agreement or understanding with any person (other than this Agreement) that would give rise to a valid claim against any of them or any Underwriter for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Securities.

(oo) The Company has not taken, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities or any debt security of the Company; and the Company has not taken any action which, to its knowledge, may result in the loss by any of the Underwriters of the ability to engage in permitted stabilization activities; and the Company has been informed of the guidance relating to stabilization provided by the U.K. Financial Services Authority (including, without limitation, Section MAR 2 Annex 2G of the Financial Services Handbook).

(pp) No forward-looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act) contained in the Registration Statement, the Disclosure Package and the Final Prospectus has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith.

(qq) Nothing has come to the attention of the Company that has caused the Company to believe that the statistical and market-related data included or incorporated by reference in the Registration Statement, the Disclosure Package and the Final Prospectus is not based on or derived from sources that are reliable and accurate in all material respects.

(rr) Except as described in the Registration Statement, the Disclosure Package and the Final Prospectus, under the current laws and regulations of Brazil and any applicable political subdivision thereof, all principal, interest (including additional interest, if any), additional amounts, if any, and other payments due or made on the Securities may be paid by the Company to the holder of the Securities in U.S. dollars; and except as described in the Registration Statement, the Disclosure Package and the Final Prospectus, all such payments made to holders of Securities who are non-residents of Brazil will not be subject to income, withholding or other taxes under laws and regulations of Brazil or any political subdivision or taxing authority thereof or therein and will otherwise be free and clear of any other tax, duty, withholding or deduction in Brazil or any political subdivision or taxing authority thereof or therein and without the necessity of obtaining any governmental authorization in Brazil or any political subdivision or taxing authority thereof or therein.

(ss) It is not necessary under the laws of Brazil that any holder of Securities, the Underwriters or the Trustee should be licensed, qualified or entitled to carry on business in Brazil, (i) to enable any of them to enforce their respective rights under this Agreement or the issuance or sale by the Company of the Securities or any other document to be delivered in connection herewith or therewith or (ii) solely by reason of the execution, delivery or performance of any such document.

(tt) (i) The choice of the law of the State of New York as the governing law of this Agreement, the Indenture and the Securities is a valid choice of law under the laws of Brazil and the Company has no reason to believe that it will not be honored by the courts of Brazil; provided, however, that these laws as interpreted are not found to contravene Brazilian national sovereignty, good morals or public policies (as to which the Company has no reason to believe that such choice of law would contravene Brazilian national sovereignty, good morals or public policies); (ii) the submission by the Company to the non-exclusive jurisdiction of the U.S. federal or state courts sitting in The City of New York and County of New York set forth in this Agreement and the Indenture constitute valid and legally binding obligations of the Company; and (iii) service of process effected in the manner set forth in this Agreement and the Indenture, assuming validity under the laws of the State of New York, will be effective, insofar as Brazilian law is concerned, to confer valid personal jurisdiction over the Company.

(uu) To ensure the legality, validity or enforceability of this Agreement, the Indenture and the Securities, it is not necessary that any such document be filed or recorded with any court or other authority in Brazil, except that (i) (w) the signature of

any party executing such documents outside of Brazil must be notarized by a notary public licensed as such under the law of the place of signing, (x) the signature of such notary public shall have been authenticated by a Brazilian consular office having jurisdiction over the place of execution and (y) this Agreement, the Indenture and the Securities, must be translated into the Portuguese language by a sworn translator, which signature must be notarized by a notary public, (z) this Agreement, the Indenture and the Securities, together with their respective sworn translations referred to in item “y” above, must be registered with the appropriate registry of deeds and documents in Brazil, which registration may be made at any time for judicial enforcement of this Agreement, the Indenture or the Securities in Brazil and (ii) in case of court proceedings filed against the Company in Brazil, certain court costs and deposits to guarantee judgment might become due and any Brazilian or foreign plaintiff not resident in Brazil or who is abroad during the course of a legal proceeding will be required to make cash deposits as security for process costs and for third party attorney’s fees, should such plaintiff not have any real property in Brazil to assure payment thereof, in accordance with Article 835 of the Brazilian Civil Procedure Code, except in case of execution writs or counterclaims as established under Article 836 of the Brazilian Civil Procedure Code.

(vv) The Company and its obligations under this Agreement, the Indenture and the Securities are subject to suit, and none of the Company, any of its Subsidiaries or any of its or their properties or assets has any right of immunity, on any grounds, from any action, suit or proceeding, from the giving of any relief in any action, suit or proceeding, from set-off or counter claim, from the jurisdiction of any Brazilian or U.S. federal or New York state court, as the case may be from service of process, attachment upon or prior to judgment, or attachment in aid of execution of judgment, or from execution of a judgment, or from other legal process or proceeding for the giving of any relief or for the enforcement of a judgment, in any such court, with respect to its obligations, liabilities or any other matter arising out of or relating to this Agreement, the Indenture or the Securities, as the case may be.

For purposes of this Section 1 as well as for Section 5 hereof, references to “the Registration Statement, the Disclosure Package and the Final Prospectus” are to each of them as a separate or stand-alone document (and not the three of them taken together), so that representations, warranties, agreements, conditions and legal opinions will be made, given or measured independently in respect of each of the Registration Statement, the Disclosure Package and the Final Prospectus.

Any certificate signed by one or more directors, officers or representatives of the Company as provided in its Bylaws (estatuto social) and delivered to the Representatives or U.S. or Brazilian counsel to the Underwriters in connection with the offering of the Securities shall be deemed a representation and warranty by the Company as to matters covered thereby, to each Underwriter.

SECTION 2. Representations, Warranties and Agreements of the Underwriters. Each Underwriter hereby severally represents, warrants and agrees that:

(a) It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any Free Writing Prospectus other than (i) a Free Writing Prospectus that is not required under the Securities Act to be filed, (ii) any Issuer Free Writing Prospectus listed on Schedule II to the Terms Agreement or prepared pursuant to Section 4(d) hereto or (iii) any Free Writing Prospectus prepared by such Underwriter and approved by the Company in advance in writing.

(b) Unless otherwise specified in the Terms Agreement, it has not and will not, without the prior written consent of the Company, use any Free Writing Prospectus that contains the final terms of the Securities unless such terms have previously been included in a Free Writing Prospectus filed with the Commission; provided, however, that it may use a term sheet substantially in the form of the Final Term Sheet without the consent of the Company.

(c) It is not subject to any pending proceeding under Section 8A of the Securities Act with respect to the offering (and will promptly notify the Company if any such proceeding against it is initiated during the period in which a prospectus relating to the Securities is required to be delivered under the Securities Act).

(d) Unless otherwise specified in the Terms Agreement, it has not offered or sold and will not offer or sell the Securities publicly (as defined for purposes of the securities laws of Brazil) in Brazil.

(e) Unless otherwise specified in the Terms Agreement, in relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), each Underwriter represents and agrees that with effect from and including the date on which the Prospectus Directive (as defined below) is implemented in that Relevant Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of the Securities to the public in that Relevant Member State prior to the publication of a prospectus in relation to the Securities which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the Relevant Implementation Date, make an offer of the Securities to the public in that Relevant Member State at any time:

(i) to legal entities which are authorized or regulated to operate in the financial markets or, if not so authorized or regulated, whose corporate purpose is solely to invest in securities;

(ii) to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000; and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts; or

(iii) in any other circumstances which do not require the publication by the issuer of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this Section 2(e), the expression an “offer of Securities to the public” in relation to any Securities in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Securities to be offered so as to enable an investor to decide to purchase or subscribe the Securities, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, and references to the “Prospectus Directive” means Directive 2003/71/EC of the European Parliament and of the Council of the European Union of November 4, 2003, and includes any relevant implementing measure in each Relevant Member State.

SECTION 3. Purchase and Sale. Subject to the terms and conditions and in reliance upon the representations and warranties set forth in the Agreement, the Company agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company, at the purchase price set forth in the Terms Agreement the principal amount of the Securities set forth opposite such Underwriter’s name in the Terms Agreement.

Delivery of and payment for the Securities shall be made on the date and at the time specified in the Terms Agreement or at such time on such later date not more than five Business Days after the foregoing date as you shall designate, which date and time may be postponed by agreement among the Representatives and the Company or as provided in Section 8 hereof (such date and time of delivery and payment for the Securities being herein called the “Closing Date”). Delivery of the Securities shall be made to you for the respective accounts of the several Underwriters against payment by the several Underwriters through you of the purchase price thereof to or upon the order of the Company by wire transfer payable in same-day funds to an account specified by the Company. Delivery of the Securities shall be made through the facilities of The Depository Trust Company (“DTC”) unless you shall otherwise instruct.

SECTION 4. Agreements of the Company. The Company agrees with each Underwriter as follows:

(a) Immediately following the execution of the Terms Agreement, the Company will prepare a Final Prospectus setting forth the principal amount of Securities covered thereby and any terms thereof not otherwise specified in the Base Prospectus or any Preliminary Prospectus, the names of the Underwriters participating in the offering and the principal amount of Securities that each Underwriter severally has agreed to purchase, the names of the Underwriters acting as bookrunners, managers or co-managers in connection with the offering, if any, the price at which the Securities are to be purchased by the Underwriters from the Company, the initial public offering price, the selling concession and reallowance, if any, and such other information as the Company and the Underwriters deem appropriate in connection with the offering of the Securities. The Company will within the time periods specified by Rule 424(b) transmit copies of the Final Prospectus to the Commission for filing pursuant to Rule 424(b) of the Securities Act and will furnish to the Underwriters as many copies of the Final Prospectus as you shall reasonably request.

(b) Prior to the termination of the offering of the Securities, the Company will not file any amendment to the Registration Statement or supplement (including the Final Prospectus or any Preliminary Prospectus) to the Base Prospectus unless you have been furnished a copy for review prior to filing and the Company will not file any such proposed amendment or supplement to which you reasonably object. The Company will promptly advise you (1) when the Final Prospectus, and any supplement thereto, has been filed (if required) with the Commission pursuant to Rule 424(b), (2) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (3) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (4) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act, (5) of the receipt by the Company of any notice of objection to the use of the Registration Statement, any amendment or supplement thereto pursuant to Rule 401(g)(2) under the Securities Act, any Preliminary Prospectus, or the Final Prospectus, and (6) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its reasonable best efforts to prevent the issuance of any such stop order or notice of objection or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(c) The Company shall pay the required Commission filing fees relating to the Securities within the time required by Rule 456(b)(1) under the Securities Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Securities Act.

(d) Unless otherwise specified in the Terms Agreement, the Company will prepare a final term sheet (the “Final Term Sheet”), containing solely a description of final terms of the Securities and the offering thereof, substantially in the form set forth in Exhibit B hereto and in the form approved by you and attached as Schedule III to the Terms Agreement and will file the Final Term Sheet pursuant to Rule 433(d) under the Securities Act within the time required by such Rule.

(e) If, at any time prior to the filing of the Final Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Company promptly will (i) notify you so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

(f) If, at any time when a prospectus relating to the Securities is required to be delivered under the Securities Act, any event or development occurs as a result of which

the Final Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Final Prospectus to comply with the Securities Act or the Exchange Act, the Company promptly will (i) notify you thereof (provided, however, that any press release notifying the public thereof shall satisfy the requirements of this clause (i)); (ii) prepare and file with the Commission an amendment or supplement which will correct such statement or omission or effect such compliance; and (iii) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request.

(g) As soon as practicable, the Company will make generally available to its security holders and to the Representatives an earnings statement or statements of the Company and its Subsidiaries which will satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 under the Securities Act.

(h) Upon request, the Company will furnish to the Representatives and to counsel for the Underwriters, without charge, signed or conformed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Securities Act, as many copies of each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Representatives may reasonably request.

(i) The Company agrees that, unless it has or shall have obtained the prior written consent of the Representatives, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a Free Writing Prospectus required to be filed by the Company with the Commission or retained by the Company under Rule 433 under the Securities Act, other than a Free Writing Prospectus containing the information contained in the Final Term Sheet prepared and filed pursuant to Section 4(d) hereto; provided that the prior written consent of Representatives shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule II to the Terms Agreement. Any such Free Writing Prospectus consented to by the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 under the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(j) The Company will furnish, upon request of an Underwriter, for a period of two years from the date of the Agreement (unless otherwise publicly available on the Commission’s ▇▇▇▇▇ website or the Company’s website) (i) copies of any reports or other communications which the Company shall send to its shareholders or which the Company shall from time to time publish or publicly disseminate; (ii) copies of all annual and other reports filed with the Commission on Forms 20-F and 6-K, or such other

similar form as may be designated by the Commission; and (iii) copies of documents or reports filed with any securities exchange on which any class of securities of the Company is listed, in each case, as soon as such reports, communications or documents become available.

(k) The Company will apply the net proceeds from the sale of the Securities in the manner set forth under the caption “Use of Proceeds” in the Final Prospectus.

(l) The Company will endeavor to qualify the Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request and will continue such qualifications in effect so long as required for the distribution and resale of the Securities; provided, however, that the Company shall not be required to (i) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject; and provided, further, that the Company shall not be obligated to maintain any such qualification for more than one year from the date of this Agreement.

(m) Other than the Securities, during the period from the date hereof through and including the date that is 30 days after the date hereof, the Company will not, without the prior written consent of the Representatives, issue, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by the Company and having a tenor of more than one year, provided that nothing in this clause (m) is intended to prevent (i) the prepayment of any existing indebtedness of the Company; (ii) the Company from entering into a five-year Revolving Credit Facility with lenders of its choosing; (iii) the Company from entering into any export financing transaction with multilateral agencies or (iv) the Company from entering into any financing from Financiadora de Estudos e Projetos – FINEP or the Banco Nacional de Desenvolvimento Econômico e Social – BNDES.

(q) The Company will use its reasonable best efforts to list the Securities on the New York Stock Exchange.

(r) All payments to be made by the Company to the Underwriters under this Agreement shall be paid without set-off or counterclaim, and free and clear of and without deduction or withholding for or on account of, any present or future taxes, levies,

imposts by Brazil or by any department, agency or other political subdivision or taxing authority thereof or therein, and all interest, penalties or similar liabilities with respect thereto (collectively, “Taxes”). If any Taxes are required by law to be deducted or withheld in connection with such payments, the Company will pay an additional amount (“Additional Amount”) so that the full amount of such payment is received by the Underwriters; provided , however , that such Additional Amount will not be paid on account of any Taxes imposed or withheld by reason of the failure by the Underwriters to comply with a request of the payer addressed to the Underwriters to provide certification, information, documents or other evidence concerning the nationality, residence or identity of the Underwriters, which is required by a statute, treaty, regulation or administrative practice of the jurisdiction imposing such Taxes as a precondition to exemption from all or part of such Taxes.

(d) The Company shall have furnished to you a certificate, signed by two executive officers of the Company with specific knowledge of the financial matters of the Company, reasonably satisfactory to you, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Disclosure Package, the Final Prospectus and any supplements or amendments thereto, and the Terms Agreement and that:

SECTION 6. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors, officers, employees, agents and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, documented fees and other expenses of counsel incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, any Preliminary Prospectus, the Disclosure Package, the Final Prospectus, or any Issuer Free Writing Prospectus (or any amendment or supplement thereto) or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any Underwriter Information.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, officers, employees, agents and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any Underwriter Information (it being understood and agreed that the only such information consists of the information specified under “Underwriter Information” in the Terms Agreement).

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either Section 6(a) or Section 6(b), such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 6 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 6. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 6 that the Indemnifying Person may designate in such proceeding and shall pay the documented fees and expenses of such proceeding and shall pay the documented fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any

Indemnified Person shall have the right to retain its own counsel (including local counsel), but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm of counsel (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors, officers, employees, agents and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, its affiliates, directors, officers, employees, agents and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) If the indemnification provided for in Section 6(a) and Section 6(b) is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or

omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Underwriters in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 6(d). The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in Section 6(d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 6 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

SECTION 7. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange, the American Stock Exchange, the São Paulo Stock Exchange, the Nasdaq Stock Market, the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any securities exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by U.S. federal, New York State or Brazilian authorities or a material disruption in commercial banking or securities settlement or clearance services shall have occurred; or (iv) there shall have occurred any outbreak or escalation of hostilities or acts of terrorism or declaration of national emergency or any change in financial markets or any calamity or crisis, either within or outside Brazil and/or the United States, that, in

the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery, of the Securities on the terms and in the manner contemplated by this Agreement, the Registration Statement, the Disclosure Package and the Final Prospectus.

SECTION 8. Default by an Underwriter. If one or more of the Underwriters shall fail at the Closing Date to purchase the Securities which it or they are obligated to purchase under the Agreement (the “Defaulted Securities”), then you shall have the right, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, by the end of such 36 hours you shall not have completed such arrangements for the purchase of all the Defaulted Securities then:

(a) if the aggregate amount of Defaulted Securities does not exceed 10% of the aggregate amount of the Securities to be purchased pursuant to the Terms Agreement, the non-defaulting Underwriters shall be obligated to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all such non-defaulting Underwriters, or

(b) if the aggregate amount of Defaulted Securities exceeds 10% of the aggregate amount of the Securities to be purchased pursuant to the Terms Agreement, this agreement shall terminate, without any liability on the part of any non-defaulting Underwriter or the Company.

In the event of a default by any Underwriter or Underwriters as set forth in this Section 8, either you or the Company shall have the right to postpone the Closing Date for a period not exceeding seven days in order that any required changes in the Registration Statement or Prospectus or in any other documents or arrangements may be effected. Any action taken under this Section 8 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under the Agreement.

SECTION 9. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all costs and expenses incident to the performance of its respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any stamp or other taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Registration Statement, the Disclosure Package and the Final Prospectus (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the documented fees and expenses of the Company’s counsel and independent registered public accounting firms; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate (including the related documented fees and expense of U.S. counsel for the Underwriters) and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of U.S. counsel for the Underwriters); (vi) any fees charged by rating agencies for rating

the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with the approval of the Securities for book-entry transfer by DTC; (ix) all expenses incurred by the Company and the Underwriters in connection with any “road show” presentation (including any electronic “road show” presentation) to potential investors; (x) all expenses and application fees related to the listing of the Securities on the New York Stock Exchange; (xi) the travel and related expenses incurred by the Company and the Underwriters in connection with attending or hosting “road show” meetings with, or presentations to, prospective purchasers of the Securities; and (xii) the documented fees and expenses of the U.S. and Brazilian counsel to the Underwriters.

(b) If (i) this Agreement is terminated pursuant to Section 7, (ii) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement except for termination pursuant to Section 8, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the documented fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

SECTION 10. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and any officers, directors, affiliates and controlling persons referred to in Section 6 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

SECTION 11. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters.

SECTION 12. Miscellaneous. (a) All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication. Notices to the Underwriters shall be directed to you at the address indicated in the Terms Agreement. Notices to the Company shall be given to them at ▇▇▇▇▇▇▇ ▇.▇., ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇, 12227-901 São ▇▇▇▇ dos ▇▇▇▇▇▇, São Paulo, Brazil, (fax: (▇▇-▇▇) ▇▇▇▇-▇▇▇▇); Attention: Financial Director and (fax: (▇▇-▇▇) ▇▇▇▇-▇▇▇▇); Attention: Legal Department.

(b) This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York. The transactions contemplated by this Agreement have been proposed by the Underwriters to the Company for the purposes of paragraph 2 of Article 9 of Brazilian Decree-Law No. 4,657 dated September 4, 1942 and for no other purpose or reason whatsoever.

(c) The Company agrees that any suit, action or proceeding against the Company brought by any Underwriter, the directors, officers, employees, Affiliates and agents of any Underwriter, or by any person who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any U.S. federal or state court in the Borough of Manhattan, The City of New York, and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding. The Company hereby appoints National Registered Agents, Inc., with offices at ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇ as its authorized agent (the “Authorized Agent”) upon whom process may be served in any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated herein that may be instituted in any U.S. federal or state court in New York City, by any Underwriter, the directors, officers, employees, Affiliates and agents of any Underwriter, or by any person who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and expressly accepts the non-exclusive jurisdiction of any such court in respect of any such suit, action or proceeding. Such appointment shall be irrevocable by the Company. The Company hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process until June 15, 2022, and the Company agrees to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by any Underwriter, the directors, officers, employees, affiliates and agents of any Underwriter, or by any person who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, in any court of competent jurisdiction in Brazil. The parties hereto each hereby waive any right to trial by jury in any action, proceeding or counterclaim arising out of or relating to this Agreement.

(d) Each reference in this Agreement to U.S. dollars (the “relevant currency”), including by use of the symbol “US$”, is of the essence. To the fullest extent permitted by law, the obligation of the Company in respect of any amount due under this Agreement will, notwithstanding any payment in any other currency (whether pursuant to a judgment or otherwise), be discharged only to the extent of the amount in the relevant currency that the party entitled to receive such payment may, in accordance with its normal procedures, purchase with the sum paid in such other currency (after any premium and costs of exchange) on the business day immediately following the day on which such party receives such payment. If the amount in the relevant currency that may be so purchased for any reason falls short of the amount originally due, the Company will pay such additional amounts, in the relevant currency, as may be necessary to compensate for the shortfall. Any obligation of the Company not discharged by such payment will, to the fullest extent permitted by applicable law, be due as a separate and independent obligation and, until discharged as provided herein, will continue in full force and effect.

(e) To the extent that the Company has or hereafter may acquire any immunity (sovereign or otherwise) from any legal action, suit or proceeding, from jurisdiction of any court or from set-off or any legal process (whether service or notice, attachment in aid or otherwise)

with respect to itself or any of its property, the Company hereby irrevocably waives and agrees not to plead or claim such immunity in respect of its obligations under this Agreement to the fullest extent permitted by applicable law.

(f) No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

(g) The Company acknowledges and agrees that: (i) nothing herein shall create a fiduciary or agency relationship between the Company, on the one hand, and the Underwriters, on the other; (ii) the Underwriters are not acting as advisors, expert or otherwise, to the Company in connection with this offering, sale of the Securities or any other services the Underwriters may be deemed to be providing hereunder, including, without limitation, with respect to the public offering price of the Securities and the Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby and the Underwriter shall have no responsibility or liability to the Company with respect to such investigation or appraisal, (iii) the relationship between the Company, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iv) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (v) the Underwriters and their respective affiliates may have interests that differ from those of the Company.

(h) This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

(i) The headings herein are included for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.
