regulation purporting to prohibit the payment by the Guarantor of any amount payable by it under this Guaranty;

Obligations or any other obligations of any other person or entity under or in respect of the Transaction Documents, or any other amendment or waiver of or any consent to departure from any Transaction Document, including, without limitation, any
increase in the obligations of the Issuer under the Indenture and the Notes as a result of further issuances, any rescheduling of the Issuer’s obligations under the Notes of the Indenture or otherwise;

any claim of set-off or other right which the Guarantor may have at any time against the Issuer or the Trustee, whether in connection with this transaction or with any unrelated transaction.

Guaranteed Obligations is rescinded or must otherwise be returned by any Noteholder or any other person or entity upon the insolvency, bankruptcy or reorganization of the Issuer or the Guarantor or otherwise, all as though such payment had not been
made. 
 SECTION 4. Independent Obligation The obligations of the Guarantor hereunder are independent of the
Issuer’s obligations under the Notes and the Indenture. The Trustee, on behalf of the Noteholders, may neglect or forbear to enforce payment under the Indenture and the Notes, without in any way affecting or impairing the liability of the
Guarantor hereunder. The Trustee shall not be obligated to exhaust recourse or remedies against the Issuer to recover payments required to be made under the Indenture nor take any other action against the Issuer before being entitled to payment from
the Guarantor of all amounts contemplated in Section 2 hereof owed hereunder or proceed against or have resort to any balance of any deposit account or credit on the books of the Trustee in favor of the Issuer or in favor of the Guarantor.
Without limiting the generality of the foregoing, the Trustee shall have the right to bring a suit directly against the Guarantor, either prior or subsequent to or concurrently with any lawsuit against, or without bringing suit against, the Issuer.

this Section 5 are knowingly made in contemplation of such benefits.

extent permitted under Brazilian law, any benefit it may be entitled to under Articles 827, 834, 835, 838 and 839 of the Brazilian Civil Code, and under Article 595, caput, of the Brazilian Civil Procedure Code.

irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Issuer or any other guarantor that arise from the existence, payment, performance or enforcement of the Guarantor’s obligations under or in
respect of this Guaranty or any other Transaction Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification, or to participate in any claim or remedy of the Trustee, on behalf of
the Noteholders, against the Issuer or any other person, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuer or any other
person, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations and all other amounts payable under
this Guaranty shall have been paid in full in cash. If any amount shall be paid to the Guarantor in violation of the immediately preceding sentence at any time prior to the later of (a) the payment in full in cash of the Guaranteed Obligations
and all other amounts payable under this Guaranty and (b) the date on which all of the obligations of the Issuer under the Indenture and the Notes have been discharged in full (the later of such dates being the “Termination
Date”), such amount shall be paid over to and received and held by the Trustee in trust for the benefit of the Noteholders, shall be segregated from other property and funds of the Guarantor and shall forthwith be paid or delivered to the
Trustee in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Guaranty, whether matured or unmatured, in accordance with the
terms of the Indenture. If (i) the Guarantor shall make payment to any Noteholder or the Trustee, on behalf of the Noteholders, of all or any part of the Guaranteed Obligations, (ii) all of the Guaranteed Obligations and all other amounts
payable under this Guaranty shall have been paid in full in cash and (iii) the Termination Date shall have occurred, then the Trustee, on behalf of the Noteholders, will, at the Guarantor’s written request and expense, execute and deliver
to the Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to the Guarantor of an interest in the Guaranteed Obligations resulting from such payment made by the
Guarantor pursuant to this Guaranty. 

  
 11

Guaranty; 
 (B) the Successor Company (jointly and severally with the Guarantor unless the Guarantor shall have

transfer, lease or otherwise dispose of all or substantially all of its properties, assets or revenues to a direct or indirect Subsidiary of the Guarantor in cases when the Guarantor is the surviving entity in such transaction and such transaction

Subsidiaries taken as a whole; or 

  
 13 









 (C) any direct or indirect Subsidiary of the Guarantor may merge or
consolidate with or into, or convey, transfer, lease or otherwise dispose of assets to, any direct or indirect Subsidiary of the Guarantor; or 
 (D) any direct or indirect Subsidiary of the Guarantor may liquidate or dissolve if the Guarantor determines in good faith that such liquidation or dissolution is in the best interests of the Guarantor,
and would not result in a Material Adverse Effect on the Guarantor and its Subsidiaries taken as a whole and if such liquidation or dissolution is part of a corporate reorganization of the Guarantor. 

(g) Negative Pledge. So long as any Note remains outstanding, the Guarantor will not create or permit any Lien, other than a
Permitted Lien, on any of the Guarantor’s assets to secure (i) any of the Guarantor’s Indebtedness or (ii) the Indebtedness of any other person, unless the Guarantor contemporaneously creates or permits such Lien to secure
equally and ratably the Guarantor’s obligations under this Guaranty or the Guarantor provides such other security for the Notes as is duly approved by the Trustee, at the direction of the Noteholders, in accordance with the Indenture. In
addition, the Guarantor will not allow any of the Guarantor’s Material Subsidiaries to create or permit any Lien, other than a Permitted Lien, on any of the Guarantor’s assets to secure (i) any of the Guarantor’s Indebtedness,
(ii) any of the Indebtedness of the Guarantor’s Material Subsidiaries or (iii) the Indebtedness of any other person, unless it contemporaneously creates or permits the Lien to secure equally and ratably the Guarantor’s
obligations under this Guaranty or the Guarantor or such Material Subsidiary provides such other security for the Notes as is duly approved by the Trustee, at the direction of the Noteholders, in accordance with the Indenture. 

(h) Provision of Financial Statements and Reports. (i) The Guarantor will provide to the Trustee, in English or accompanied
by a certified English translation thereof, (A) within 90 calendar days after the end of each fiscal quarter (other than the fourth quarter), its unaudited and consolidated balance sheet and statement of income calculated in accordance with
Reporting GAAP and (B) within 120 calendar days after the end of each fiscal year, its audited and consolidated balance sheet and statement of income calculated in accordance with Reporting GAAP. 

(ii) The Guarantor will provide, together with each of the financial statements delivered pursuant to Sections 7(h)(i)(A) and (B), an
Officer’s Certificate stating that a review of the activities of the Guarantor and the Issuer has been made during the period covered by such financial statements with a view to determining whether the Guarantor and the Issuer have kept,
observed, performed and fulfilled their covenants and agreements under this Guaranty and that no Default or Event of Default has occurred during such period or, if one or more have actually occurred, specifying all such events and what actions have
been taken and will be taken with respect to such Default or Event of Default.

 (iii) The Guarantor shall, whether or not it is required to file reports
with the SEC, file with the SEC and deliver to the Trustee (for redelivery to all Noteholders) all reports and other information as it would be required to file with the SEC under the Exchange Act if it were subject to those regulations;
provided, however, that if the SEC does not permit the filing described in the first sentence of this Section 7(h)(iii), the Guarantor will provide annual and interim reports and other information to the Trustee within the same time
periods that would be applicable if the Guarantor were required and permitted to file these reports with the SEC. 
 (iv) Delivery of the above reports to the Trustee is for informational purposes only and the Trustee’s receipt of such reports shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the Guarantor’s compliance with any of its covenants in the Indenture (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate). 

SECTION 8. Amendments, Etc. No amendment or waiver of any provision of this Guaranty and no consent to any departure by the
Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by the Trustee and the Guarantor, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for
which given. For the avoidance of doubt, Article IX of the Indenture shall apply to an amendment to this Guaranty to determine whether the consent of Holders is required for an amendment and if so, the required percentage of Holders of the Notes
required to approve the amendment. 
 SECTION 9. Indemnity The Guarantor agrees to fully indemnify the Trustee and any
predecessor Trustee and their agents for, and to hold it harmless against, any and all loss, liability, damages, claims or expense arising out of or in connection with the performance of its duties under this Guaranty, including the costs and
expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder except to the extent that any such loss, liability or expense may be attributable to its negligence
or bad faith.

Section 9 and Section 14 shall survive the payment in full of the Guaranteed Obligations and all of the other amounts payable under this Guaranty, the termination of this Guaranty and/or the resignation or removal of the Trustee.

 SECTION 12. No Waiver; Remedies. No failure on the part of the Trustee to exercise, and no delay in exercising, any

 16 









 SECTION 13. Continuing Agreement; Assignment of Rights Under the Indenture and the
Notes. This Guaranty is a continuing guaranty and shall (a) remain in full force and effect until the later of (i) the repayment in full by the Issuer of all amounts due and owing under the Indenture with respect to the Notes and
(ii) the repayment in full of all Guaranteed Obligations and all other amounts payable under this Guaranty, (b) be binding upon the Guarantor, its successors and assigns and (c) inure to the benefit of and be enforceable by the
Trustee, on behalf of Noteholders, and their successors, transferees and assigns. Without limiting the generality of clause (c) of the immediately preceding sentence, any Noteholder may assign or otherwise transfer its rights and obligations
under the Indenture (including, without limitation, the Note held by it) to any other person or entity, and such other person or entity shall thereupon become vested with all the benefits in respect thereof granted to such Noteholder herein or
otherwise, in each case as and to the extent provided in the Indenture. The Guarantor shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of all of the Noteholders. 

SECTION 14. Currency Rate Indemnity (a) The Guarantor shall (to the extent lawful) indemnify the Trustee and the Noteholders and
keep them indemnified against: 
 (i) in the case of nonpayment by the Guarantor of any amount due to the
Trustee, on behalf of the Noteholders, under this Guaranty any loss or damage incurred by any of them arising by reason of any variation between the rates of exchange used for the purposes of calculating the amount due under a judgment or order in
respect thereof and those prevailing at the date of actual payment by the Guarantor; and 
 (ii) any deficiency
arising or resulting from any variation in rates of exchange between (a) the date as of which the local currency equivalent of the amounts due or contingently due under this Guaranty or in respect of the Notes is calculated for the purposes of
any bankruptcy, insolvency or liquidation of the Guarantor, and (b) the final date for ascertaining the amount of claims in such bankruptcy, insolvency or liquidation. The amount of such deficiency shall be deemed not to be increased or reduced
by any variation in rates of exchange occurring between the said final date and the date of any bankruptcy, insolvency or liquidation or any distribution of assets in connection therewith. 

  
 17 









 (b) The Guarantor agrees that, if a judgment or order given or made by any court for the
payment of any amount in respect of its obligations hereunder is expressed in a currency (the “Judgment Currency”) other than pounds sterling (the “Denomination Currency”), it will indemnify the relevant Holder and
the Trustee against any deficiency arising or resulting from any variation in rates of exchange between the date at which the amount in the Denomination Currency is notionally converted into the amount in the Judgment Currency for the purposes of
such judgment or order and the date of actual payment thereof. 
 (c) The above indemnities shall constitute separate and
independent obligations of the Guarantor from its obligations hereunder, will give rise to separate and independent causes of action, will apply irrespective of any indulgence granted from time to time and will continue in full force and effect
notwithstanding any judgment or the filing of any proof or proofs in any bankruptcy, insolvency or liquidation of the Guarantor for a liquidated sum or sums in respect of amounts due under this Guaranty, or under the Indenture or the Notes or under
any judgment or order. 
 SECTION 15. Governing Law; Jurisdiction; Waiver of Immunity, Etc. 

(a) This Guaranty shall be governed by, and construed in accordance with, the laws of the State of New York. 

(b) The Guarantor hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any
New York State court or federal court of the United States of sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Guaranty or any of the other Transaction Documents to
which it is or is to be a party, or for recognition or enforcement of any judgment, and the Guarantor hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such
New York State court or, to the extent permitted by law, in such federal court. The Guarantor agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in
any other manner provided by law. Nothing in this Guaranty or any other Transaction Document shall affect any right that any party may otherwise have to bring any action or proceeding against the Issuer or the Guarantor, as the case may be, relating
to this Guaranty or any other Transaction Document in the courts of any jurisdiction. 

  
 18 









 (c) The Guarantor hereby irrevocably appoints and empowers the New York office of
Petróleo Brasileiro S.A., located at 570 Lexington Avenue, 43rd Floor, New York, New York 10022 as its authorized agent (the “Process Agent”) to accept and acknowledge for and on its behalf and on behalf of its property
service of any and all legal process, summons, notices and documents which may be served in any such suit, action or proceedings in any New York State court or United States federal court sitting in the State of New York in the Borough of Manhattan
and any appellate court from any thereof, which service may be made on such designee, appointee and agent in accordance with legal procedures prescribed for such courts. The Guarantor will take any and all action necessary to continue such
designation in full force and effect and to advise the Trustee of any change of address of such Process Agent and; should such Process Agent become unavailable for this purpose for any reason, the Guarantor will promptly and irrevocably designate a
new Process Agent within New York, New York, which will agree to act as such, with the powers and for the purposes specified in this subsection (c). The Guarantor irrevocably consents and agrees to the service of any and all legal process, summons,
notices and documents out of any of the aforesaid courts in any such action, suit or proceeding by hand delivery, to it at its address set forth in Section 10 or to any other address of which it shall have given notice pursuant to
Section 10 or to its Process Agent. Service upon the Guarantor or the Process Agent as provided for herein will, to the fullest extent permitted by law, constitute valid and effective personal service upon it and the failure of the Process
Agent to give any notice of such service to the Guarantor shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon. 

(d) The Guarantor irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that
it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Guaranty or any of the other Transaction Documents to which it is or is to be a party in any New York State or federal court.
The Guarantor hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such suit, action or proceeding in any such court. 

(e) THE GUARANTOR HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON
CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS GUARANTY, ANY OF THE TRANSACTION DOCUMENTS, THE ADVANCES OR THE ACTIONS OF ANY NOTEHOLDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF. 

  
 19 









 (f) This Guaranty and any other documents delivered pursuant hereto, and any actions taken
hereunder, constitute commercial acts by the Guarantor. The Guarantor irrevocably and unconditionally and to the fullest extent permitted by law, waives, and agrees not to plead or claim, any immunity from jurisdiction of any court or from any legal
process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) for itself, the Issuer or any of their property, assets or revenues wherever located with respect to its obligations,
liabilities or any other matter under or arising out of or in connection with this Guaranty, any of the Transaction Documents or any document delivered pursuant hereto, in each case for the benefit of each assigns, it being intended that the
foregoing waiver and agreement will be effective, irrevocable and not subject to withdrawal in any and all jurisdictions, and, without limiting the generality of the foregoing, agrees that the waivers set forth in this subsection (f) shall have
the fullest scope permitted under the United States Foreign Sovereign Immunities Act of 1976 and are intended to be irrevocable for the purposes of such act. 
 SECTION 16. Execution in Counterparts This Guaranty and each amendment, waiver and consent with respect hereto may be executed in any number of counterparts and by different parties thereto in
separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Guaranty by
telecopier shall be effective as delivery of an original executed counterpart of this Guaranty. 
 SECTION 17. Entire
Agreement This Guaranty, together with the Indenture and the Notes, sets forth the entire agreement of the parties hereto with respect to the subject matter hereof.
