(v) any taking, release or amendment or waiver of, or consent to departure from, any other guaranty or agreement similar in function to this Guaranty, for all or any of the obligations of the Issuer under the Indenture or the Notes;

(vi) any manner of sale or other disposition of any assets of any Noteholder;

(vii) any change, restructuring or termination of the corporate structure or existence of the Issuer or the Guarantor or any Subsidiary thereof or any change in the name, purposes, business, capital stock (including ownership thereof) or constitutive documents of the Issuer or the Guarantor;

(viii) any failure of the Trustee to disclose to the Guarantor any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of the Issuer or any of its Subsidiaries (the Guarantor hereby waiving any duty on the part of the Trustee or any Noteholders to disclose such information);

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.

SECTION 5. Waivers and Acknowledgments (a) The Guarantor hereby unconditionally and irrevocably waives promptness, diligence, notice of acceptance, presentment, demand for performance, notice of nonperformance, default, acceleration, protest or dishonor and any other notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that the Trustee, on behalf of the Noteholders, protect, secure, perfect or insure any Lien or any property subject thereto or exhaust any right or take any action against the Issuer or any other Person.

(b) The Guarantor hereby unconditionally and irrevocably waives any right to revoke this Guaranty and acknowledges that this Guaranty is continuing in nature and applies to the Guaranteed Obligations, whether the same are existing now or in the future.

(c) The Guarantor hereby unconditionally and irrevocably waives (i) any defense arising by reason of any claim or defense based upon an election of remedies by any Noteholder or the Trustee on behalf of the Noteholders that in any manner impairs, reduces, releases or otherwise adversely affects the subrogation, reimbursement, exoneration, contribution or indemnification rights of the Guarantor or other rights of the Guarantor to proceed against the Issuer or any other person or entity and (ii) any defense based on any right of set-off or counterclaim against or in respect of the Guaranteed Obligations of the Guarantor hereunder.

(e) The Guarantor acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements contemplated by the Transaction Documents and that the waivers set forth in this Section 5 are knowingly made in contemplation of such benefits.

(f) The recitals contained in this Guaranty shall be taken as the statements of the Issuer and the Guarantor, as applicable, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representation as to the validity or sufficiency of this Guaranty, of any offering materials, the Indenture or of the Notes.

Claims Against the Issuer The Guarantor hereby unconditionally and 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.

SECTION 7. Covenants For so long as the Notes remain outstanding or any amount remains unpaid on the Notes and the Indenture, the Guarantor will, and will cause each of its Subsidiaries, as applicable, to comply with the terms and covenants set forth below (except as otherwise provided in a duly authorized amendment to this Guaranty as provided herein):

(a) Performance of Obligations. The Guarantor shall pay all amounts owed by it and comply with all its other obligations under the terms of this Guaranty and the Indenture in accordance with the terms thereof.

(b) Maintenance of Corporate Existence. The Guarantor will (i) maintain in effect its corporate existence and all registrations necessary therefor except as otherwise permitted by Section 7(e) and (ii) take all actions to maintain all rights, privileges, titles to property, franchises, concessions and the like necessary or desirable in the normal conduct of its business, activities or operations; provided, however, that this Section 7(b) shall not require the Guarantor to maintain any such right, privilege, title to property or franchise if the failure to do so does not, and will not, have a Material Adverse Effect.

(c) Maintenance of Office or Agency. So long as any of the Notes are outstanding, the Guarantor will maintain in the Borough of Manhattan, The City of New York, an office or agency where notices to and demands upon the Guarantor in respect of this Guaranty may be served, and the Guarantor will not change the designation of such office without prior written notice to the Trustee and designation of a replacement office in the same general location.

(d) Ranking. The Guarantor will ensure at all times that its obligations under this Guaranty will constitute the general, senior, unsecured and unsubordinated obligations of the Guarantor and will rank pari passu, without any preferences among themselves, with all other present and future senior unsecured and unsubordinated obligations of the Guarantor (other than obligations preferred by statute or by operation of law) that are not, by their terms, expressly subordinated in right of payment to the obligations of the Guarantor under this Guaranty.

(e) Limitation on Consolidation, Merger, Sale or Conveyance. (i) The Guarantor will not, in one or a series of transactions, consolidate or amalgamate with or merge into any corporation or convey, lease, spin-off or transfer substantially all of its properties, assets or revenues to any person or entity (other than a direct or indirect Subsidiary of the Guarantor) or permit any person or entity (other than a direct or indirect Subsidiary of the Guarantor) to merge with or into it, unless:

(A) either the Guarantor is the continuing entity or the person (the “Successor Company”) formed by such consolidation or into which the Guarantor is merged or that acquired or leased such property or assets of the Guarantor will assume (jointly and severally with the Guarantor unless the Guarantor shall have ceased to exist as a result of such merger, consolidation or amalgamation), by an amendment to this Guaranty (the form and substance of which shall be previously approved by the Trustee), all of the Guarantor’s obligations under this Guaranty;

(B) the Successor Company (jointly and severally with the Guarantor unless the Guarantor shall have ceased to exist as part of such merger, consolidation or amalgamation) agrees to indemnify each Noteholder against any tax, assessment or governmental charge thereafter imposed on such Noteholder solely as a consequence of such consolidation, merger, conveyance, transfer or lease with respect to the payment of principal of, or interest on, the Notes pursuant to this Guaranty;

(C) immediately after giving effect to such transaction, no Event of Default, and no Default has occurred and is continuing; and

(D) the Guarantor has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such merger consolidation, sale, transfer or other conveyance or disposition and the amendment to this Guaranty comply with the terms of this Guaranty and that all conditions precedent provided for herein and relating to such transaction have been complied with.

(ii) Notwithstanding anything to the contrary in the foregoing, so long as no Default or Event of Default shall have occurred and be continuing at the time of such proposed transaction or would result therefrom and the Guarantor has delivered written notice of any such transaction to the Trustee (which notice shall contain a description of such merger, consolidation or conveyance):

(A) the Guarantor may merge, amalgamate or consolidate with or into, or convey, transfer, lease, spin-off 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 would not have a Material Adverse Effect on the Guarantor and its Subsidiaries taken as a whole, it being understood that if the Guarantor is not the surviving entity, the Guarantor shall be required to comply with the requirements set forth in the previous paragraph; or

(B) any direct or indirect Subsidiary of the Guarantor may merge or consolidate with or into, or convey, transfer, lease, spin-off or otherwise dispose of assets to, any person (other than the Guarantor or any of its Subsidiaries or Affiliates) in cases when such transaction would not have a Material Adverse Effect on the Guarantor and its Subsidiaries taken as a whole; or

(C) any direct or indirect Subsidiary of the Guarantor may merge or consolidate with or into, or convey, transfer, lease, spin-off 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.

(f) 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.

(g) 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. For purposes of this Section 7(g), as long as the financial statements or reports are publicly available and accessible electronically by the Trustee, the filing or electronic publication of such financial statements or reports shall comply with the Guarantor’s obligation to deliver such statements and reports to the Trustee hereunder. The Guarantor shall provide the Trustee with prompt written notification at such time that the Guarantor ceases to be a reporting company. The Trustee shall have no obligation to determine if and when the Guarantor’s financial statements or reports are publicly available and accessible electronically.

(ii) The Guarantor will provide, together with each of the financial statements delivered pursuant to Sections 7(g)(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 12. No Waiver; Remedies. No failure on the part of the Trustee to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

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.

(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 U.S. dollars (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.

(c) The Guarantor hereby irrevocably appoints and empowers the New York office of Petróleo Brasileiro S.A., located at ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ 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.

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.
