Obligations and would be owed by the Issuer to the Trustee or any Noteholder under the Indenture and the Notes but for the fact

that the Guarantor’s obligations hereunder shall terminate following payment by the Issuer and/or the Guarantor of the entire
principal, all accrued interest and all other amounts due and owing in respect of the Notes and the Indenture. All amounts payable
by the Guarantor hereunder shall be payable in U.S. dollars and in immediately available funds to the Trustee.

to have been received by the Trustee on the next succeeding Business Day.

 

SECTION
3.      Guaranty Absolute.

or any other obligations of the Issuer, the Issuer’s Subsidiaries or the Guarantor’s Subsidiaries under or in respect
of the Indenture and the Notes or any other document or agreement, and a separate action or actions may be brought and prosecuted
against the Guarantor to enforce this Guaranty, irrespective of whether any action is brought against the Issuer or whether the
Issuer is joined in any such action or actions. The liability of the Guarantor under this Guaranty shall be irrevocable, absolute
and unconditional irrespective of, and the Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire
in any way relating to, any or all of the following:

(iv) any change in the time, manner
or place of payment of, or in any other term of, all or any of the Guaranteed 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;

 

    8

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);

 

(ix) the failure of any other
person or entity to execute or deliver any other guaranty or agreement or the release or reduction of liability of any other guarantor
or surety with respect to the Indenture;

 

(x) any other circumstance (including,
without limitation, any statute of limitations) or any existence of or reliance on any representation by the Trustee or any Noteholder
that might otherwise constitute a defense available to, or a discharge of, the Issuer or the Guarantor or any other party; or

 

(xi) 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.

 

(b) This Guaranty shall continue to be effective
or be reinstated, as the case may be, if at any time any payment of any of the 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.

 

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

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.

 

(d) The Guarantor hereby unconditionally
and irrevocably waives any duty on the part of the Trustee or any Noteholder to disclose to the Guarantor any matter, fact or thing
relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of the Issuer now
or hereafter known by the Trustee or any Noteholder, as applicable.

 

(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.

 

    10

     

    

 

(g) The Guarantor unconditionally and irrevocably
waives, to the fullest 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 794, caput, of the Brazilian Civil Procedure Code.

 

SECTION
6.      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):

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.

long as any of the Notes are outstanding, the Guarantor will maintain in the United States, 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 or agency in the United States.

 

(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.

 

    12

     

    

 

(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 its 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 the lien to secure equally and ratably its obligations under the guaranties or the Guarantor provides other
security for its obligations under this Guaranty and the Indenture as is duly approved by a resolution of the Noteholders in accordance
with the Indenture. In addition, the Guarantor will not allow any of its Material Subsidiaries, if any, to create or permit any

(ii) any of the Material Subsidiary’s Indebtedness or (iii) the Indebtedness of any other Person, unless the Guarantor contemporaneously
creates or permits the Lien to secure equally and ratably the Guarantor’s obligations under this Guaranty and the Indenture
or the Guarantor provides such other security for its obligations under this Guaranty and the Indenture as is duly approved by
the Trustee, at the discretion of the Noteholders in accordance with the Indenture.

sheet and statement of income calculated in accordance with IFRS 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 IFRS. 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(g)(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).

8.       Amendments,
Etc. No amendment or waiver of any provision of this Guaranty and no consent to any departure by the Guarantor therefrom shall

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.

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.

 

(a) 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.

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.

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 state or Federal court in the Borough of Manhattan, The City of New York, State of New
York. 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.

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.

(n)         
Early Redemption for Tax Reasons. The Notes may be redeemed at the option of the Company, in whole but not
in part, at any time at a Redemption Price equal to the principal amount thereof plus accrued and unpaid interest to the Redemption
Date if and when, as a result of any change in, execution of, or amendment to, any laws or regulations or ruling promulgated thereunder
of the jurisdiction in which the Company is incorporated (or, in the case of a successor Person to the Company, of the jurisdiction
in which such successor Person is organized or any political subdivision or taxing authority thereof or therein) or the official
entry or any change in the official application or interpretation of such laws, regulations or rulings, or any change in the official
application of or interpretation of, or any execution of or amendment to, any treaty or treaties affecting taxation to which such
jurisdiction or such political subdivision or taxing authority (or such other jurisdiction or political subdivision or taxing authority)
is a party, which change, execution or amendment becomes effective on or after the date hereof (or in the case of a successor Person
to the Company, the date on which such successor Person became such pursuant to Section 8.01 and 8.02 of the Original Indenture),

of doubt, the Company shall have the option to so redeem the Notes in the event that it is required to pay Dutch Withholding Tax
Act 2021 Additional Amounts; provided, however, that the Company shall take reasonable measures to avoid any withholding
tax on interest payments under the Notes as per the Dutch Withholding Tax Act 2021 directly resulting from the purchase by the
Company or its affiliates of any Notes; provided, further, that prior to giving the notice of redemption of the Notes (A)
the Company or its successor shall deliver to the Trustee a Director’s Certificate to the effect that the obligations of
the Company or its successor to pay Dutch Withholding Tax Act 2021 Additional Amounts cannot be avoided by the Company or its successor
taking reasonable measures available to it, and (B) the Company or its successor shall deliver to the Trustee an Opinion of Counsel
stating that the Company or its successor would be obligated to pay Dutch Withholding Tax 2021 Additional Amounts. The Trustee
shall accept such Director’s Certificate and Opinion of Counsel as sufficient evidence of the satisfaction of the conditions
precedent set forth above, and shall be conclusive and binding on the Holders. For purposes of Section 11.08 of the Original Indenture,
the reincorporation of the Company shall be treated as the adoption of a successor entity, provided, however, that redemption under
Section 11.08 of the Original Indenture shall not be available if the reincorporation was performed in anticipation of a change
in, execution of or amendment to any laws or treaties or the official application or interpretation of any laws or treaties of
such new jurisdiction of incorporation that would result in an obligation to pay Additional Amounts.

 

(o)         
Conversion: The Notes will not be convertible into, or exchangeable for, any other securities.

This Note is one of a
duly authorized issue of notes of PETROBRAS GLOBAL FINANCE B.V., a private company incorporated with limited liability under the
laws of The Netherlands (the “Issuer”), designated as its 5.600% Global Notes due 2031 (the “Notes”),
issued in an initial aggregate principal amount of U.S.$1,000,000,000 under the Amended and Restated Second Supplemental Indenture
(the “Second Supplemental Indenture”), effective as of October 21, 2020, by and among the Issuer, Petróleo
Brasileiro S.A. – Petrobras, a mixed capital company (sociedade de economia mista) organized under the laws of Brazil
(“Petrobras”), and The Bank of New York Mellon, a New York banking corporation, as Trustee (the “Trustee”),
to the Indenture, dated as of August 28, 2018 (the “Original Indenture”, and as supplemented by the Amended
and Restated Second Supplemental Indenture and any further supplements thereto with respect to the Notes, the “Indenture”),
by and among the Issuer and the Trustee. The aggregate principal amount of Notes issued for the series is U.S.$2,500,000,000. Reference
is hereby made to the Indenture for a statement of the respective rights, limitations of interests, benefits, obligations and duties
thereunder of the Issuer, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated
and delivered. All capitalized terms used in this Note which are defined in the Indenture and not otherwise defined herein shall
have the meanings assigned to them in the Indenture.

 

The Issuer, for value
received, hereby promises to pay to Cede & Co., or its registered assigns, as nominee of The Depository Trust Company (“DTC”),
and as the Holder of record of this Note, the principal amount specified above in U.S. dollars on January 3, 2031 (or earlier as
provided for in the Indenture) upon presentation and surrender hereof, at the office or agency of the Trustee referred to below.

 

As provided for in the
Indenture, the Issuer promises to pay interest on the outstanding principal amount hereof, from June 3, 2020, semi-annually in
arrears on January 3 and July 3 of each year, (each such date, an “Interest Payment Date”), commencing January
3, 2021 at a rate equal to 5.600% per annum, and will initially accrue from the date of issuance and thereafter from the last Interest
Payment Date to which interest has been paid. Interest payable, and punctually paid or duly provided for, on this Note on any Interest
Payment Date will, as provided in the Indenture, be paid in U.S. dollars to the Person in whose name this Note (or one or more
predecessor Notes) is registered at the close of business on the Business Day preceding such interest payment.

 

    

     

    

 

Payment of the principal
of and interest on this Note will be payable by wire transfer to a U.S. dollar account maintained by the Holder of this Note as
reflected in the Note Register of the Trustee. In the event the date for any payment of the principal of or interest on any Note

made on the next succeeding Business Day. Interest shall accrue on the Notes at the rate of 5.600% per annum until all required
amounts due in respect of the Notes have been paid. Interest accrued with respect to this Note shall be calculated based on a 360-day
year of twelve 30-day months.

 

The Notes are subject
to redemption by the Issuer on the terms and conditions specified in the Indenture.

 

This Note does not purport
to summarize the Indenture, and reference is made to the Indenture for information with respect to the respective rights, limitations
of interests, benefits, obligations and duties thereunder of the Issuer, the Trustee and the Holders.

 

If an Event of Default
shall occur and be continuing, the outstanding principal amount of all the Notes may become or may be declared due and payable

principal, all accrued interest and all other amounts due and owing in respect of the Notes and the Indenture. All amounts payable
by the Guarantor hereunder shall be payable in U.S. dollars and in immediately available funds to the Trustee.

to have been received by the Trustee on the next succeeding Business Day.

 

SECTION
3.      Guaranty Absolute.

now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Noteholder under its Notes or the
Indenture. The obligations of the Guarantor under or in respect of this Guaranty are independent of the Guaranteed Obligations
or any other obligations of the Issuer, the Issuer’s Subsidiaries or the Guarantor’s Subsidiaries under or in respect
of the Indenture and the Notes or any other document or agreement, and a separate action or actions may be brought and prosecuted
against the Guarantor to enforce this Guaranty, irrespective of whether any action is brought against the Issuer or whether the
Issuer is joined in any such action or actions. The liability of the Guarantor under this Guaranty shall be irrevocable, absolute
and unconditional irrespective of, and the Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire
in any way relating to, any or all of the following:

 

(i) any lack of validity or enforceability
of any of the Transaction Documents;

 

(ii) any provision of applicable
Law or regulation purporting to prohibit the payment by the Issuer of any amount payable by it under the Indenture and the Notes;

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

 

(iv) any change in the time, manner
or place of payment of, or in any other term of, all or any of the Guaranteed 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;

 

    8

     

     

(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

(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);

 

(ix) the failure of any other
person or entity to execute or deliver any other guaranty or agreement or the release or reduction of liability of any other guarantor
or surety with respect to the Indenture;

 

(x) any other circumstance (including,
without limitation, any statute of limitations) or any existence of or reliance on any representation by the Trustee or any Noteholder
that might otherwise constitute a defense available to, or a discharge of, the Issuer or the Guarantor or any other party; or

 

(xi) 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.

 

(b) This Guaranty shall continue to be effective
or be reinstated, as the case may be, if at any time any payment of any of the 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.

 

    9

     

     

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.

 

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.

 

(d) The Guarantor hereby unconditionally
and irrevocably waives any duty on the part of the Trustee or any Noteholder to disclose to the Guarantor any matter, fact or thing
relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of the Issuer now
or hereafter known by the Trustee or any Noteholder, as applicable.

 

(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.

 

    10

     

     

(g) The Guarantor unconditionally and irrevocably
waives, to the fullest 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 794, caput, of the Brazilian Civil Procedure Code.

 

SECTION
6.      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.

 

    11

     

     

(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 United States, 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 or agency in the United States.

 

(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.

 

    12

     

     

(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 its 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 the lien to secure equally and ratably its obligations under the guaranties or the Guarantor provides other
security for its obligations under this Guaranty and the Indenture as is duly approved by a resolution of the Noteholders in accordance
with the Indenture. In addition, the Guarantor will not allow any of its Material Subsidiaries, if any, 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 Material Subsidiary’s Indebtedness or (iii) the Indebtedness of any other Person, unless the Guarantor contemporaneously
creates or permits the Lien to secure equally and ratably the Guarantor’s obligations under this Guaranty and the Indenture
or the Guarantor provides such other security for its obligations under this Guaranty and the Indenture as is duly approved by
the Trustee, at the discretion of the Noteholders in accordance with the Indenture.

 

    13

     

     

(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 IFRS 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 IFRS. 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(g)(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.

 

    14

     

     

SECTION
9.      Indemnity. The

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
11.    Survival. Without prejudice

the agreements and obligations of the Guarantor contained in Section 2 (with respect to the payment of all other amounts owed under

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 right hereunder shall operate as a waiver thereof;

of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

 

    15

     

     

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.

 

(a) 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.

 

(b) 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.

 

    16

     

     

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 state or Federal court in the Borough
of Manhattan, The City of New York, State of New York, 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 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.

 

(c) The Guarantor hereby irrevocably appoints
and empowers Petrobras America Inc., with offices located at 10350 Richmond Ave., Suite 1400, Houston, TX 77042 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 state
or Federal court in the Borough of Manhattan, The City of New York, State of New York, 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 the United States, 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 state or Federal court in the Borough of Manhattan, The City of New York, State of New
York. 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.

 

    17

     

     

(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.

 

(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. Counterparts may be delivered via facsimile, electronic mail (including any
electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures
and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered
shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.
