Securities Act of 1933, as amended (the “Act”), is a “seasoned” foreign government issuer within the meaning of Commission Release No. 33-6424 and has filed with the Securities and Exchange Commission (the
“Commission”) a registration statement on Schedule B (File No. 333-[•]) relating to debt securities and warrants, including the Securities; such registration statement and any post-effective amendment thereto, each in
the form heretofore delivered to you or your counsel (excluding exhibits to such registration statements), have been declared effective by the Commission in such form; no other document with respect to such registration statement has heretofore been
filed with the Commission (other than the documents incorporated therein by reference and prospectuses filed pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, each in form heretofore delivered to you or your
counsel); and no stop order suspending the effectiveness of such registration statement has been issued and no 

 
proceeding for that purpose has been initiated or threatened by the Commission. Such registration statement, as amended as of the time each part thereof
became effective, including all exhibits thereto and any documents incorporated by reference therein, and any prospectus supplement deemed to be a part thereof that has not been superseded or modified, are hereinafter collectively called the
“Registration Statement”; “Registration Statement” without reference to a time means the Registration Statement as of the time of the first contract of sale for any Securities; the basic prospectus contained in the
Registration Statement, in the form in which it has most recently been filed with the Commission on or prior to the date of this Agreement, is hereinafter called the “Basic Prospectus”. The final prospectus supplement dated [•]
relating to the offering of the Securities to be filed with the Commission pursuant to Rule 424 under the Act is hereinafter called the “Prospectus Supplement”. Any preliminary prospectus (including any preliminary prospectus
supplement) relating to the Securities which has heretofore been filed with the Commission pursuant to Rule 424(b) under the Act is hereinafter called the “Preliminary Prospectus”. The Basic Prospectus, as amended and supplemented
immediately prior to the Applicable Time (as defined in Section 1(c) hereof) by the Preliminary Prospectus, is hereinafter called the “Pricing Prospectus”; the form of the final prospectus relating to the Securities filed with
the Commission pursuant to Rule 424(b) under the Act in accordance with Section 5(a) hereof is hereinafter called the “Prospectus”; any reference herein to the Basic Prospectus, the Pricing Prospectus, any Preliminary
Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein, as of the date of such prospectus; any reference to any amendment or supplement to the Basic Prospectus, any Preliminary Prospectus
or the Prospectus shall be deemed to refer to and include any post-effective amendment to the Registration Statement, any prospectus supplement relating to the Securities filed with the Commission pursuant to Rule 424(b) under the Act and any
annual reports on Form 18-K and any amendments to such Form 18-K on Form 18-K/A (including all exhibits thereto) (collectively, a “Form 18-K”) filed after the date of the Prospectus or the Basic Prospectus, as the case may be, under the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), and incorporated therein, in each case after the date of the Basic Prospectus, such Preliminary Prospectus or the Prospectus, as the case may be; and any reference to any
amendment to the Registration Statement shall be deemed to refer to and include any Form 18-K of the Republic filed under the Exchange Act after the effective date of the Registration Statement that is incorporated by reference in the Registration

 (i) This Agreement has been duly authorized, executed and delivered by Brazil and constitutes the valid and legally binding agreement of Brazil; 
 (ii) The Securities have been duly authorized, executed, issued and delivered by Brazil, and assuming due authentication by the Fiscal
Agent, constitute valid and legal obligations of Brazil enforceable in accordance with their terms and entitled to the benefits provided by the Fiscal Agency Agreement, subject, as to enforcement, to bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles; 
 (iii) The Fiscal Agency Agreement has been duly authorized, executed and delivered by Brazil and, assuming due authorization, execution and delivery thereof by the Fiscal Agent, constitutes the valid and legally
binding agreement of Brazil enforceable in accordance with its terms, subject, as to enforcement, to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting
creditors’ rights and to general equity principles; 
 (iv) Neither the execution and delivery of this Agreement, the
Fiscal Agency Agreement or the Securities, nor the consummation of the transactions herein or therein contemplated, nor compliance with the terms and provisions hereof or thereof, including performance of each of the obligations contained in the
Securities, (A) to such counsel’s best knowledge after due inquiry, will conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, loan agreement or other agreement
or instrument for borrowed money known to such counsel to which Brazil is a party, (B) will conflict with, violate or result in a breach of the Constitution of Brazil as amended to the date hereof or as currently proposed to be amended by any
currently pending resolution of the Brazilian National Congress (i.e., a resolution that initially has been voted upon and approved by both houses of Congress), or any statutes, laws, decrees or regulations of Brazil, (C) to such
counsel’s best knowledge after due inquiry, will conflict with or result in a breach of any of the terms, conditions or provisions of any treaty, convention or agreement to which Brazil is a party or constitute a default thereunder or
(D) will result in the creation or imposition of any mortgage, lien, charge or encumbrance of any nature whatsoever upon any of the revenues or assets of Brazil under any such treaty, convention or agreement which, in the case of
Clause (A), (B), (C), or (D), could have a material adverse effect on the financial, economic or fiscal condition of Brazil or affect the validity or enforceability of the Securities; 
 (v) The Registration Statement and the Prospectus and their filing with the Commission have been duly authorized by and on behalf of
Brazil, and the Registration 

  

 -12- 

 
Statement has been duly executed by and on behalf of Brazil; Roberto Abdenur has been duly appointed as the Authorized Representative of Brazil in connection
with the Registration Statement; the information in the Registration Statement and the Prospectus stated on the authority of public officials of Brazil has been stated in their official capacities thereunto duly authorized by Brazil; statements with
respect to matters of Brazilian law set forth in the Registration Statement, in the Basic Prospectus under the caption “Arbitration and Enforceability” and in the Prospectus Supplement under the caption “Description of the Global
Bonds – Arbitration and Enforceability” are correct in all material respects; 
 (vi) All Brazilian Government
Authorizations (which shall be specified in such opinion) of or with any Brazilian Government Agency required by Brazil for the execution and delivery of this Agreement and the Fiscal Agency Agreement and for the execution, the issuance, sale and
delivery of the Securities, and the consummation by Brazil of the transactions contemplated by this Agreement, the Fiscal Agency Agreement or the Securities have been obtained and are in full force and effect; 
 (vii) Under the laws of Brazil, neither Brazil nor any of its property has any immunity from the jurisdiction of any Brazilian court or
from the execution of any judgment in Brazil (except for the limitation on alienation of public property under Article 100 of the Civil Code of Brazil) or from enforcement therein of any arbitral award on the grounds of sovereignty or otherwise; the
execution of an arbitral award, as well as the execution of any judgment, against Brazil in Brazil are only available in accordance with the procedures set forth in Article 730 et seq. of the Brazilian Civil Procedure Code; 
 (viii) (A) The agreement of the parties to this Agreement, the Fiscal Agency Agreement and the Securities that these agreements shall
be governed by, and construed in accordance with, the laws of the State of New York would be recognized and effective in the courts of Brazil in any action or proceeding involving Brazil arising out of or relating to this Agreement, the Fiscal
Agency Agreement or the Securities, if giving effect to such law would not be against the principles of Brazilian public policy as set forth in Article 17 of Decree Law 4,657. In light of, among other things, the contents of Articles 9 and
17 of Decree Law No. 4,657, such counsel has no reason to believe that giving effect to the laws of the State of New York governing the obligations of Brazil under this Agreement, the Fiscal Agency Agreement and the Securities would be against
Brazilian public policy. (B) (i) The submission of Brazil pursuant to Section 15 hereof, Section 14 of the Fiscal Agency Agreement and the Securities to arbitral proceedings in New York, New York, (ii) the agreement by
Brazil under Section 15 hereof, Section 14 of the Fiscal Agency Agreement and in the Securities that any judicial proceedings for the recognition of an award rendered in an arbitration, including any proceeding required for the purposes of
converting an arbitral award obtained in New York into a judgment, be heard in the United States District Court for the Southern District of New York and Brazil’s submission to the exclusive jurisdiction of such court for the sole and limited
purpose of such a proceeding and (iii) the appointment of the Authorized Agent (as defined herein, in the Fiscal Agency Agreement and in the Securities) as its authorized agent for the purposes described in Section 15 hereof, in
Section 14 of the Fiscal Agency Agreement and in the Securities are each valid and legally binding on Brazil. (C) Any award (including, without limitation, any decision, an “Award”) of an arbitral tribunal under or pursuant to
the provisions of Section 15 hereof, Section 14 of the Fiscal Agency Agreement and the Securities which conforms with Brazilian public policy and law will 

  

 -13- 

 
be enforceable against Brazil in the Federal courts of Brazil without reexamination of the merits if such Award is ratified by the Superior Court of Justice
of Brazil. Such ratification can be obtained if such Award (i) fulfills all formalities required for the enforceability thereof under the laws of the country where the same was granted; (ii) was issued by a competent arbitral tribunal
after service of process upon the parties to the action as required by applicable laws; (iii) is not subject to appeal; (iv) was authenticated by a Brazilian consulate in the country where the same was issued; and (v) is not against
the principles of Brazilian public policy as set forth in Article 17 of Decree Law 4,657. Furthermore, counsel will have assumed that the language of Section 15 of this Agreement, Section 14 of the Fiscal Agency Agreement and in the
Securities does not constitute, under the law of the State of New York or the Federal law of the United States, a contractual consent by Brazil to the jurisdiction of any court outside Brazil except to the extent necessary to obtain judicial
recognition of the arbitral award, including any proceeding required for the purposes of converting an arbitral award into a judgment. (D) Service of process effected in the manner set forth in Section 15 hereof, in Section 14 of the
Fiscal Agency Agreement and in the Securities will be effective, insofar as Brazilian law is concerned, to confer valid personal jurisdiction over Brazil to the extent of any action referred to therein. Any judgment obtained in the United States
District Court for the Southern District of New York issued in a proceeding for the recognition of an award rendered in an arbitration pursuant to Section 15 hereof, Section 14 of the Fiscal Agency Agreement and the Securities, including
any proceeding for the conversion of an arbitral award obtained in New York into a judgment, would be enforceable against Brazil in the courts of Brazil, subject to the limitation described in clause (vii) above; 
 (ix) To ensure the legality, validity, enforceability or admissibility in evidence of this Agreement, the Fiscal Agency Agreement or the
Securities, it is not necessary that this Agreement, the Fiscal Agency Agreement, the Securities or any other document be filed, registered or recorded with, or executed before, any court or other authority in Brazil (other than the translation and
publication thereof in accordance with Section 5(h) hereof and the registration of the payment schedule for the Securities with the Central Bank of Brazil in accordance with Section 5(d) hereof), or that any registration charge or stamp or
similar tax be paid on or in respect of this Agreement, the Fiscal Agency Agreement, the Securities or any other document, provided that the electronic registration through the ROF must be completed in accordance with Section 5(d) hereof;

 (x) There is no tax, levy, deduction, charge or withholding imposed by Brazil or any political subdivision thereof either
(A) on or by virtue of the execution, delivery or recognition of this Agreement or the Fiscal Agency Agreement or (B) on any payment to be made by Brazil hereunder or any payment of principal or interest under any Security; provided that
such Security is held by an individual who is not a resident of Brazil or by a non-Brazilian corporation directly and not through a permanent establishment thereof in Brazil; 
 (xi) The statements in the Prospectus Supplement under the caption “Taxation—Brazilian Taxation” and in the Basic
Prospectus under the caption “Debt Securities—Tax Withholding; Payment of Additional Amounts” fairly summarize the provisions of Brazilian tax law described therein; 
  

 -14- 

 (xii) Other than as set forth in the Prospectus, to the best of such counsel’s
knowledge after due inquiry, there are no legal or governmental proceedings or arbitrations pending to which Brazil is a party which, if determined adversely to Brazil, would individually or in the aggregate have a material adverse effect on
Brazil’s financial, economic or fiscal condition or its ability to perform its obligations under this Agreement, the Fiscal Agency Agreement or the Securities; and, to the best of such counsel’s knowledge after due inquiry, no such
proceedings are threatened; 
 (xiii) This Agreement, the Fiscal Agency Agreement and the Securities are in proper legal form
under the laws of Brazil for the enforcement thereof against Brazil under the laws of Brazil; 
 (xiv) No stamp or other
issuance or transfer taxes or duties and no capital gains, income, withholding, or other taxes are payable by or on behalf of the Underwriters to Brazil or to any political subdivision or taxing authority thereof or therein in connection with
(A) the issuance, sale and delivery by Brazil of the Securities to or for the respective accounts of the Underwriters or (B) the sale and delivery outside Brazil by the Underwriters of the Securities to the initial purchasers thereof in
the manner contemplated herein; and 
 (xv) Under the laws of Brazil, pursuant to Senate Resolutions No. 96 of 1989 and
No. 82 of 1990, as amended, any agreement related to the incurrence of external indebtedness to which Brazil is a party must provide that arbitration be the sole and exclusive remedy for the parties to such agreement for any dispute,
controversy or claim brought outside of Brazil for the enforcement of such agreement against Brazil; Brazil is prohibited from submitting to the jurisdiction of a foreign court for the purpose of an adjudication on the merits; and each of the
Underwriting Agreement, the Fiscal Agency Agreement and the Securities would not be a valid and legally binding agreement of Brazil if it were not to provide that all parties to the Underwriting Agreement, the Fiscal Agency Agreement or the
Securities, as the case may be, shall submit any dispute, controversy or claim brought outside of Brazil to arbitration. 
 In
giving such opinion, such counsel may state that his opinion is limited to matters of Brazilian law and may rely upon the opinion referred to in Section 8(e) as to all matters of United States and New York law. 
 In addition to the foregoing, such counsel will confirm that the Registration Statement, the Basic Prospectus, the Pricing Disclosure
Package and the Prospectus have been prepared by appropriate representatives of Brazil and its instrumentalities, including representatives of the Ministry of Finance, and representatives of the Procuradoria-Geral da Fazenda Nacional (Office
of the Attorney General of the National Treasury) (“PGFN”) have participated in discussions regarding the Registration Statement, the Basic Prospectus, the Pricing Disclosure Package and the Prospectus with such representatives, U.S.
counsel for Brazil, the representatives of the Underwriters and their Brazilian and U.S. counsel. Under the direction of the Procurador-Geral da Fazenda, PGFN has been apprised of and has reviewed the disclosure requirements under applicable
United States securities laws and regulations and has reviewed the Registration Statement, the Basic Prospectus, the Pricing Disclosure Package and the Prospectus. Based on such discussions and review, and without independent investigation or
verification of the correctness or completeness of the information 

  

 -15- 

 
included in the Registration Statement, the Basic Prospectus, the Pricing Disclosure Package and the Prospectus, such counsel will advise the Underwriters,
on behalf of PGFN, that, subject to the limitations described below, nothing has come to PGFN’s attention which has caused it to believe that any part of the Registration Statement, when such part became effective, contained an untrue statement
of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading or that the Basic Prospectus, the Prospectus or any further amendment or supplement thereto, as of the
date of the Prospectus or any further amendment or supplement thereto, contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they
were made, not misleading or that, as of the date of the opinion, any of the Registration Statement, the Basic Prospectus or the Prospectus or any further amendment or supplement thereto made by Brazil prior to the date of the opinion contains an
untrue statement of material fact or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and that no information has come to such counsel’s
attention that causes such counsel to believe that the documents specified in a schedule to such counsel’s letter, consisting of those included in the Pricing Disclosure Package, as of the Applicable Time and as of the date of the
opinion, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Such counsel may
state that the PGFN is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Basic Prospectus, the Pricing Disclosure Package and the Prospectus (except to the extent
expressly set forth in clauses (v) and (xi) above), that such counsel makes no representation that PGFN has independently verified the accuracy, completeness or fairness of such statements (except as aforesaid) and that such counsel does
not express any opinion or belief as to the financial or statistical data contained in the Registration Statement, the Basic Prospectus, the Pricing Disclosure Package or the Prospectus. 
 (e) Arnold & Porter LLP, United States counsel for Brazil, shall have furnished to you their written opinion, dated the Time of
Delivery, in form and substance satisfactory to you, to the effect that: 
 (i) Assuming that the Fiscal Agency Agreement has
been duly authorized, executed and delivered by Brazil and by the Fiscal Agent, the Fiscal Agency Agreement constitutes a valid and legally binding agreement of Brazil, enforceable in accordance with its terms, subject, as to enforcement, to
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability affecting creditors’ rights and to general equity principles; 
 (ii) Assuming that the Securities have been duly authorized, executed, issued and delivered under Brazilian law and authenticated by the
Fiscal Agent, such Securities constitute valid and legally binding obligations of Brazil entitled to the benefits provided by the Fiscal Agency Agreement and enforceable in accordance with their terms, subject, as to enforcement, to bankruptcy,
insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability affecting creditors’ rights and to general equity principles; 
  

 -16- 

 (iii) No consent, approval, authorization or order of, or qualification with, any United
States Federal or New York State governmental agency or body is required for the issue and sale of the Securities or the performance by Brazil of the transactions contemplated by this Agreement or the Fiscal Agency Agreement, except such as have
been obtained under the Act and such consents, approvals, authorizations or qualifications as may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Securities; 
 (iv) Under the laws of the State of New York, assuming Brazil has duly authorized, executed and delivered this Agreement under Brazilian
law, (A) the submission of Brazil pursuant to Section 15 hereof, Section 14 of the Fiscal Agency Agreement and the Securities to arbitral proceedings in New York, New York, (B) the agreement by Brazil pursuant to Section 15
hereof, Section 14 of the Fiscal Agency Agreement and the Securities to submit to the personal jurisdiction of the United States District Court for the Southern District of New York in judicial proceedings for the recognition of an award
rendered in an arbitral proceeding, including any action to convert an arbitral Award into a judgment and (C) the appointment of the Authorized Agent (as defined herein) as its authorized agent for the purposes described in Section 15
hereof, Section 14 of the Fiscal Agency Agreement and the Securities are each valid and legally binding on Brazil; any service of process effected on such agent in the manner set forth in Section 15 hereof, Section 14 of the Fiscal
Agency Agreement and the Securities will be effective to confer valid personal jurisdiction over Brazil to the extent of any action referred to therein, subject to the limitations of the Foreign Sovereign Immunities Act of 1976, as amended;

 (v) The statements set forth in the Prospectus Supplement under the caption “Taxation — United States Federal
Income and Estate Taxation” insofar as such statements purport to describe the principal federal tax consequences of a purchase of the Securities, constitute fair summaries of such consequences; 
 (vi) The Registration Statement is effective under the Act and, to the best of such counsel’s knowledge, no stop order with respect
thereto has been issued, or proceeding for that purpose instituted or threatened by the Commission; and 
 (vii) The
statements set forth in the Prospectus Supplement under the caption “Description of the Global Bonds” and in the Basic Prospectus under the captions “Debt Securities” and “Collective Action Securities,” insofar as they
purport to constitute a summary of certain provisions of the Securities and the Fiscal Agency Agreement, provide a fair summary of such provisions. 
 In giving such opinion, such counsel may state that their opinion is limited to the Federal laws of the United States and the laws of the State of New York and may rely on the opinion referred to in Section 8(d)
as to all matters of Brazilian law. 
 In addition, Arnold & Porter LLP shall have furnished to the Underwriters a
letter, dated the Time of Delivery, confirming that as United States counsel to Brazil, such counsel reviewed the Registration Statement, the Basic Prospectus, the Pricing Disclosure Package and the Prospectus, as then amended or supplemented,
participated in discussions with representatives of Brazil and the Underwriters, and their Brazilian and U.S. counsel, and advised Brazil as to the requirements of the Act and the applicable 

  

 -17- 

 
rules and regulations thereunder; confirming that on the basis of the information that such counsel gained in the course of the performance of such services,
considered in the light of their understanding of the applicable law and the experience they have gained through their practice under the Act, in their opinion, each part of the Registration Statement, when such part became effective, and the Basic
Prospectus, the Prospectus and any further amendment or supplement thereto, as of the date of the Prospectus or any further amendment or supplement thereto, appeared on their face to be appropriately responsive in all material respects to the
requirements of the Act and the applicable rules and regulations of the Commission thereunder; nothing that came to such counsel’s attention in the course of such review has caused such counsel to believe that any part of the Registration
Statement, when such part became effective, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading or that the Basic
Prospectus, the Prospectus or any amendment or supplement thereto, as of the date of the Prospectus or any further amendment or supplement thereto, contained any untrue statement of a material fact or omitted to state any material fact necessary in
order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and nothing that has come to such counsel’s attention in the course of the limited procedures described in such letter has
caused them to believe that the Basic Prospectus or the Prospectus, as then amended or supplemented, as of the date and time of delivery of such letter, contained any untrue statement of a material fact or omitted to state any material fact
necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and that no information has come to such counsel’s attention that causes such counsel to believe that the documents
specified in a schedule to such counsel’s letter, consisting of those included in the Pricing Disclosure Package, as of the Applicable Time, contained any untrue statement of a material fact or omitted to state any material fact
necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Such counsel may state that they do not assume any responsibility for the accuracy, completeness or fairness of the
statements contained in the Registration Statement, the Basic Prospectus, the Pricing Disclosure Package or the Prospectus Supplement except to the extent of the opinion separately rendered by such counsel with respect to statements made under the
captions “Description of the Global Bonds” in the Prospectus Supplement and “Debt Securities” and “Collective Action Securities” in the Basic Prospectus, in each case as then amended or supplemented, insofar as they
purport to summarize provisions of documents therein described; that such counsel do not express any opinion or belief as to the financial statements and related schedules or other financial or statistical data or information; that such counsel do

the Minister of Finance or the Procurador-Geral da Fazenda Nacional (Attorney General of the National Treasury) of the Ministry of Finance or another duly authorized attorney of the Office of the Attorney General of the National Treasury of
the Ministry of Finance, in which such official shall state that, to the best of his knowledge after reasonable investigation: (A) the representations and warranties of Brazil in this Agreement are true and correct in all material respects with
the same effect as though such representations and warranties had been made at and as of the Time of Delivery (other than such representations and warranties 

  

 -18- 

 
which are made as of a specified date), (B) Brazil has complied with all agreements and satisfied all conditions on its part to be performed or
satisfied at or prior to the Time of Delivery, (C) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been initiated or, to the best of his knowledge, threatened by

revoked or rescinded in whole or in part, and (E) since the respective dates as of which information is given in the Prospectus, there has been no material adverse change, or any prospective material adverse change, in or affecting the
financial, economic or fiscal condition of Brazil, except as set forth in or contemplated by the Prospectus;

political condition of Brazil, in Brazilian currency exchange rates or exchange controls, or in Brazilian taxation affecting the Securities, otherwise than as set forth in or contemplated in the Prospectus, the effect of which, in any such case, is
in your judgment such as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated by the Prospectus; (B) subsequent to the execution and delivery

arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in
conformity with written information furnished to Brazil by such Underwriter in connection with the preparation thereof. 
 (b)
Each Underwriter severally and not jointly will indemnify and hold harmless Brazil against any losses, claims, damages or liabilities to which Brazil may become subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in any
Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment thereof or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under
the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made therein in reliance upon and in conformity with written information furnished to Brazil by such Underwriter through you expressly for use in
connection with the preparation thereof; and will reimburse Brazil for any legal or other reasonable and documented expenses reasonably incurred by Brazil in connection with investigating or defending any such action or claim as such expenses are
incurred and an itemized statement thereof, in reasonable detail, has been submitted to that Underwriter. 
 (c) Promptly
after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such
subsection, notify the indemnifying party in writing of the commencement thereof; but the omission to so notify the indemnifying party shall not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise
than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the
extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable costs of investigation, provided, however, that an indemnifying party shall not, in connection with any one such action or separate but substantially similar actions
arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all indemnified parties, except to the extent that local counsel, in addition to its regular counsel, is
required in order to effectively defend against such action. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate
counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) in the indemnified party’s reasonable judgment, the use of counsel chosen by the indemnifying
party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party; or (iii) the 

  

 -21- 

 
indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. No indemnifying party shall,
without the prior written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of the indemnified party
from all liability arising out of such action or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party. 
 (d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party
under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by Brazil on the one hand and the Underwriters on the other from the
offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each
indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of Brazil on the one hand and the Underwriters
on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by
Brazil on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by Brazil bear to the total underwriting discounts and commissions
received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault 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 Brazil on the one hand or such Underwriter on the other and the parties’ relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. Brazil and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) 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 which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of
the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to make any contribution payments in excess of the amount by which the total public offering price of
the Securities such Underwriter underwrote and distributed to the public exceeds the amount of any damages which 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 
 (e) The obligations of Brazil under this Section 9 shall be in addition to any liability which Brazil may otherwise have and shall
extend, upon the same terms and conditions, to each 

  

 -22- 

 
person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 9 shall be in
addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each person who signs the Registration Statement on behalf of Brazil. 
 10. Default by an Underwriter. 
 (a) If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase
such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Securities, then Brazil shall be entitled to a further period of thirty-six hours within
which to procure another party or other parties reasonably satisfactory to you to purchase such Securities on such terms. In the event that, within the respective prescribed periods, you notify Brazil that you have so arranged for the purchase of
such Securities, or Brazil notifies you that it has so arranged for the purchase of such Securities, you or Brazil shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes
may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and Brazil agrees to file promptly any amendments to the Registration Statement or the Prospectus which in your opinion may
thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such
Securities. 
 (b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter
or Underwriters by you and Brazil as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then Brazil
shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities which such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the principal amount of Securities which such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve
a defaulting Underwriter from liability for its default. 
 (c) If, after giving effect to any arrangements for the purchase
of the Securities of a defaulting Underwriter or Underwriters by you and Brazil as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount
of all the Securities, or if Brazil shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon
terminate, without liability on the part of any non-defaulting Underwriter or Brazil, except for the expenses to be borne by Brazil and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in
Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default. 
 11. Survival. The
respective indemnities, agreements, representations, warranties and other statements of Brazil and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in
full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter, or any controlling person of any Underwriter or Brazil, or any government official of Brazil, and shall
survive delivery of and payment for the Securities. 
  

 -23- 

 12. Effects of Termination. If this Agreement shall be terminated pursuant to Section 10 hereof,
Brazil shall not then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason, the Securities are not delivered by or on behalf of Brazil as provided herein, Brazil will reimburse the
Underwriters through you for all out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities, but Brazil shall then be
under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof. 
 13. Notices. All statements, requests,
notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to you in care of [name and address of the Underwriter], Attention: [•] (Facsimile: +[•]); and in
the case of [name and address of the Underwriter], Attention: [•] (Facsimile: +[•]); and if to Brazil shall be delivered or sent by mail or facsimile transmission to the address of Brazil, Attention: Procuradoria-Geral da Fazenda Nacional,
Ministério da Fazenda, Esplanada dos Ministérios, Bloco P., 8°Andar, 70048-900, Brasília-DF, Brasil (Facsimile: +55 (61) 3412-1740), Attention: Procurador-Geral da Fazenda Nacional, with a copy to: Secretaria do Tesouro
Nacional, Ministério da Fazenda, Esplanada dos Ministérios, Bloco P-Anexo A-Sala 105, 70048-900 Brasília-DF, Brasil, Attention: Coordenador-Geral da Coordenadoria de Operações da Dívida Pública -
CODIP (Facsimile: +55 (61) 3412-1534); provided, however, that any notice to an Underwriter pursuant to Section 9(c) hereof shall be delivered or sent by mail or facsimile transmission to such Underwriter at its address set forth in its
Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to Brazil. Any such statements, requests, notices or agreements shall take effect upon receipt thereof. 
 14. Binding Effect. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, Brazil and, to the extent provided
in Sections 9 and 11 hereof, the appropriate officials of Brazil, the officers and directors and each person who controls any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall
acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase. 
 15. Arbitration. 
 (a)
(i) If any dispute, controversy or claim arising out of or relating to this Agreement or the transactions contemplated hereby, including the existence, performance, interpretation, construction, breach, termination or invalidity thereof (a
“Dispute”) (other than a Dispute which is made the subject of a suit, action or proceeding brought against Brazil in a competent court in Brazil) shall arise between the Underwriters, on the one hand, and Brazil, on the other, the
Underwriters, or Brazil, as the case may be (the “Referring Party”), shall by written notice (the “Referral Notice”) to Brazil or the Underwriters, as the case may be (the “Other Party”), refer such Dispute to
arbitration and the Other Party shall upon receipt of the Referral Notice be obligated to refer such Dispute to arbitral proceedings as set forth herein. The Referral Notice shall describe the nature of such dispute, difference or question and
request the formation of an arbitral tribunal. Any Dispute shall be finally settled by arbitration in accordance with the Arbitration Rules of the United Nations Commission on International Trade Law (excluding Article 26 thereof) in effect on the
date of this Agreement (the “UNCITRAL Arbitration Rules”). The number of arbitrators shall be three, to be appointed in accordance with Section II of the UNCITRAL Arbitration Rules, which, among other things, provides that (A) the
Referring Party 
  

 -24- 

 
and the Other Party shall each appoint one arbitrator (such appointment to be made within 30 calendar days of receipt of the Referral Notice), (B) the
two arbitrators thus appointed shall choose the third arbitrator who will act as the presiding arbitrator of the tribunal and (C) if within 30 calendar days after the appointment of the second arbitrator the two arbitrators have not agreed
on the choice of a presiding arbitrator, the presiding arbitrator shall be appointed under Article 6 of the UNCITRAL Arbitration Rules. The appointing authority shall be the Chairman of the International Court of Arbitration of the
International Chamber of Commerce. The third arbitrator may be (but need not be) of the same nationality as any of the parties to the arbitration. Such arbitral proceedings shall take place in New York, New York and the language of such proceedings
shall be English. The arbitrators shall appoint a secretary with offices and facilities in New York, New York to provide administrative support for the proceedings. Any arbitral tribunal established hereunder shall state its reasons for its
decisions in writing and shall make such decisions entirely on the basis of the substantive law governing this Agreement and not on the basis of the principle of ex aequo et bono or otherwise. The decision of any such arbitral tribunal shall be
final to the fullest extent permitted by law, and Brazil hereby agrees that a court judgment may be entered thereon by the United States District Court of the Southern District of New York. Brazil agrees that in any such arbitration and in any legal
proceedings for the recognition of an award rendered in an arbitration conducted pursuant to this Section, including any proceeding required for the purposes of converting an arbitral award into a judgment, it will not raise any defense which it
could not raise but for the fact that it is a sovereign state. Brazil hereby irrevocably consents to the jurisdiction of the United States District Court for the Southern District of New York (the “New York Court”) for the limited
purpose of judicial recognition of such an arbitral award rendered against Brazil in New York, New York. 
 (b) For the sole
purpose of receiving service of process or other legal summons in connection with obtaining any judicial acceptance of any arbitral award in the New York Court, Brazil hereby represents and warrants that any such process or summons may be served
upon it, pursuant to Article 35, section I of Supplementary Law No. 73 of February 10, 1993, by delivery to the Attorney General of Brazil (Advogado-Geral da União), Palácio do Planalto, Esplanada dos
Ministérios, Anexo 1, Brasília-DF, Brazil, as its authorized agent (the “Authorized Agent”) upon whom any such process or summons may be served, of letters rogatory or by any other means permissible under the laws of the
State of New York and Brazil. Brazil hereby irrevocably waives any immunity to service of process or other legal summons effected in accordance with this subsection in respect of any action to obtain such judicial acceptance. 
 (c) Brazil hereby represents and warrants that it has no right to immunity, on the grounds of sovereignty or otherwise, from the service
of process or jurisdiction or any judicial proceedings of any competent court located in Brazil or from execution of any judgment in Brazil (except for the limitation on alienation of public property referred to in Article 100 of the Civil Code of
Brazil) or from the execution or enforcement therein of any arbitral decision in respect of any suit, action, proceeding or any other matter arising out of or relating to its obligations under this Agreement or the transactions contemplated hereby,
and to the extent that Brazil is or becomes entitled to any such immunity with respect to the service of process or jurisdiction or any judicial proceedings of any competent court located in Brazil, it does hereby and will irrevocably and
unconditionally agree not to plead or claim any such immunity with respect to its obligations or any other matter under or arising out of or in connection with this Agreement or the transactions contemplated hereby. 
 (d) Any action arising out of or based on this Agreement may be instituted by the Underwriters in any competent court in Brazil. Brazil
hereby agrees that the Underwriters shall 

  

 -25- 

 
have the right, exercisable at their sole discretion, to institute legal proceedings against Brazil through the proceedings contemplated in Articles 730
et seq. of the Brazilian Code of Civil Procedure. Brazil hereby waives irrevocably any immunity from jurisdiction or execution to which it might otherwise be entitled (except for the limitation on alienation of public property under Article 100 of
the Civil Code of Brazil) in any action arising out of or based on this Agreement which may be instituted by the Underwriters in any competent court in Brazil. 
 (e) No arbitral proceedings hereunder shall be binding upon or in any way affect the right or interest of any person other than the
claimant or respondent with respect to such arbitration. 
 16. Judgment Currency. In respect of any judgment or order given or made
for any amount due hereunder that is expressed and paid in a currency (the “Judgment Currency”) other than United States dollars, Brazil will indemnify each Underwriter against any loss incurred by such Underwriter as a result of any
variation as between (a) the rate of exchange at which the United States dollar amount is converted into the Judgment Currency for the purpose of such judgment or order and (b) the rate of exchange at which an Underwriter is able to purchase United
States dollars with the amount of Judgment Currency actually received by such Underwriter on the business day following the receipt of payment on such judgment or order. The foregoing indemnity shall constitute a separate and independent obligation
of Brazil and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of or
conversion into United States dollars. 
 17. Time of Essence. Time shall be of the essence of this Agreement. As used herein, the
term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business. 
 18.
Arm’s Length Contract. Brazil hereby acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to Brazil with respect to the offering of the Securities contemplated
hereby (including in connection with determining the terms of the offering of the Securities) and not as a financial advisor or a fiduciary to, or an agent of, Brazil or any other person. Additionally, neither Underwriter is advising Brazil or any
other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. Brazil 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 Underwriters shall have no responsibility or liability to Brazil with respect thereto, except as otherwise set forth herein. Any review by the Underwriters of Brazil, the transactions
contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of Brazil or any other person. 
 19. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without regard to the
principles of conflicts of laws thereof that would require the application of the laws of a jurisdiction other than the State of New York, except that authorization and execution of this Agreement by Brazil will be governed by the laws of
Brazil. 
 20. Representation of Underwriters. The Representatives will act for the several Underwriters in connection with this
offering of Securities, and any action under this Agreement taken by the Representatives jointly will be binding upon all the Underwriters. 
  

 -26- 

 21. Counterparts. This Agreement may be executed by any one or more of the parties hereto in any
number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument. 
 [Signature page follows] 
  

 -27- 

 If the foregoing is in accordance with your understanding, please sign and return to us counterparts
hereof, and upon the acceptance hereof by you on behalf of each of the Underwriters this letter and such acceptance hereof shall constitute a binding agreement between each of the Underwriters and Brazil. It is understood that your acceptance of
this letter on behalf of each of the Underwriters is pursuant to the authority set forth in a form of Agreement among Underwriters, the form of which shall be submitted to Brazil for examination upon request, but without warranty on your part as to
the authority of the signers thereof.

	 	Re:	Federative Republic of Brazil 

	 	 	Registration Statement on Schedule B 

 Ladies and Gentlemen:

 I, a duly authorized Acting Deputy Attorney General of the National Treasury of the Ministry of Finance of the Federative Republic of
Brazil (“Brazil”), have reviewed the above-referenced Registration Statement (the “Registration Statement”) filed on the date hereof with the Securities and Exchange Commission (the “Commission”), including the
Prospectus constituting a part thereof, the form of the Fiscal Agency Agreement including the forms of Note attached thereto, each as amended by Amendment No. 1 dated as of April 28, 2003, Amendment No. 2 dated as of March 30,
2004 and Amendment No. 3 dated as of June 28, 2004 (the “Fiscal Agency Agreement”) previously filed as part of Brazil’s Registration Statement on Schedule B (Registration No. 333-6682) and made a part of the
Registration Statement and the form of the Underwriting Agreement (the “Underwriting Agreement”) previously filed as part of Brazil’s Registration Statement on Schedule B (Registration No. 333-6682) and made a part of the
Registration Statement, pursuant to which Brazil is registering certain debt securities and warrants to purchase such debt securities (collectively, the “Securities”). 
 The issuance of the Securities has been authorized pursuant to Resolution No. 20 dated November 16, 2004 of the Federal Senate of Brazil,
enacted pursuant to Article 52 of the Constitution of the Federative Republic of Brazil. 
 It is my opinion that the Securities have been
duly authorized, and when executed and delivered by Brazil and authenticated pursuant to the Fiscal Agency Agreement and delivered to and paid for by the underwriters pursuant to the Underwriting Agreement, the Prospectus (including, without
limitation, the applicable Prospectus Supplement and Pricing Supplement) and any amendment or supplement thereto, the Securities will constitute valid and legally binding direct and unconditional obligations of Brazil under the present laws of
Brazil. 
 I hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of my name under the
heading “Validity of the Securities” in the Registration Statement. In giving the foregoing consent, I do not thereby admit that I am in the category of persons whose consent is required under Section 7 of the Act or the rules and
regulations of the Commission thereunder. 
  

	
	Very truly yours,
