(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);

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.

(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.

(b) Maintenance of Corporate Existence.

(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.

(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.

(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.

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.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than the Remaining Life and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable.

If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places. The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

“Stated Maturity” has the meaning set forth in Section 2.01(d) herein.

Ladies and Gentlemen:

I am the General Counsel of Petróleo Brasileiro S.A. — Petrobras (“Petrobras”), a sociedade de economia mista (partially state-owned enterprise) organized and existing under the laws of the Federative Republic of Brazil (“Brazil”). This opinion is being furnished to you in connection with the guaranty (the “Guaranty”) dated as of September 13, 2024 for the U.S.$1,000,000,000 aggregate principal amount of 6.000% Global Notes due 2035 (the “Notes”) by and between Petrobras, as the guarantor, and The Bank of New York Mellon, a New York banking corporation, as trustee (the “Trustee”) under the indenture dated as of August 28, 2018, by and between Petrobras’s wholly-owned subsidiary, Petrobras Global Finance B.V.

(viii)

such other documents, records and matters of law as I have deemed necessary;

We have acted as special United States counsel to Petróleo Brasileiro S.A. – Petrobras, a sociedade de economia mista (partially state-owned enterprise) organized and existing under the laws of the Federative Republic of Brazil (“Petrobras”), and Petrobras Global Finance B.V., a Dutch private company (“PGF” and, together with Petrobras, the “Companies”), in connection with PGF’s offering pursuant to a registration statement on Form F-3 (Nos. 333-261817 and 333-261817-01) of U.S.$1,000,000,000, aggregate principal amount of PGF’s 6.000% Global Notes due 2035 (the “Notes”). The Notes are to be issued under an indenture dated as of August 28, 2018 between PGF and The Bank of New York Mellon, a New York banking corporation, as trustee (the “Trustee”) (the “2018 Base Indenture”), as supplemented by the sixth supplemental indenture thereto dated as of September 13, 2024 (the “Sixth Supplemental Indenture” and, together with the 2018 Base Indenture, the “Indenture”) among PGF, Petrobras and the Trustee.

The Notes will have the benefit of a guaranty dated as of September 13, 2024 (the “Guaranty” and, together with the Notes, the “Securities”), in each case between Petrobras and the Trustee. Such registration statement, as amended as of its most recent effective date (September 3, 2024), insofar as it relates to the Securities (as determined for purposes of Rule 430B(f)(2) under the Securities Act of 1933, as amended (the “Securities Act”)), but excluding the documents incorporated by reference therein, is herein called the “Registration Statement.”

In arriving at the opinions expressed below, we have reviewed the following documents:

(a) an executed copy of the 2018 Base Indenture;

(b) a form of the Sixth Supplemental Indenture, including forms of global certificates representing the Notes; and

(e) a form of the Guaranty.

Petróleo Brasileiro S.A. – Petrobras

Petrobras Global Finance B.V., p. 2

In addition, we have reviewed originals or copies certified or otherwise identified to our satisfaction of such other documents, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinions expressed below.

In rendering the opinions expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that, when the Sixth Supplemental Indenture and the Guaranty have been duly executed and delivered by PGF and Petrobras, as applicable, in the forms thereof that we have examined, and the Notes have been duly delivered to and paid for by the purchasers thereof in the manner described in the Registration Statement and executed and authenticated, in the form thereof that we have examined, in accordance with the terms of the Indenture, the Notes will be valid, binding and enforceable obligations of PGF, entitled to the benefits of the Indenture, and the Guaranty will be valid, binding and enforceable obligations of Petrobras.

Insofar as the foregoing opinion relates to the validity, binding effect or enforceability of any agreement or obligation of PGF or Petrobras, (a) we have assumed that each of Petrobras and PGF and each other party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except that no such assumption is made as to Petrobras and PGF regarding matters of the federal law of the United States of America or the law of the State of New York that in our experience normally would be applicable to general business entities in relation to transactions of the type contemplated in the Indenture and the Notes), (b) such opinions are subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity, and (c) such opinions are subject to the effect of judicial application of foreign laws or foreign governmental actions affecting creditors’ rights.

We note that the enforceability of the waiver in Section 15 of the Guaranty and Section 1.15 of the 2018 Base Indenture by each of Petrobras and PGF, as applicable, of any immunities from court jurisdiction and from legal process is subject to the limitations imposed by the U.S. Foreign Sovereign Immunities Act of 1976.

We note that the designation in Section 15 of the Guaranty and Section 1.15 of the 2018 Base Indenture of any federal court in the Borough of Manhattan, the City of New York, State of New York, as the venue for actions or proceedings relating to the Guaranty, the Indenture and the Notes, are (notwithstanding the waiver in Section 15 of the Guaranty and Section 1.15 of the 2018 Base Indenture) subject to the power of such courts to transfer actions pursuant to 28 U.S.C. §1404(a) or to dismiss such actions or proceedings on the grounds that such a federal court is an inconvenient forum for such actions or proceedings.

We express no opinion as to the subject matter jurisdiction of any U.S. federal court to adjudicate any action relating to the Guaranty, the Indenture or the Notes where jurisdiction based on diversity of citizenship under 28 U.S.C. § 1332 does not exist.

Petróleo Brasileiro S.A. – Petrobras

Petrobras Global Finance B.V., p. 3

We express no opinion as to the enforceability of Section 14 of the Guaranty and Section 10.12 of the 2018 Base Indenture relating to currency indemnity.

We note that the waiver of defenses in Sections 3 and 5 of the Guaranty may be ineffective to the extent that any such defense involves a matter of public policy in the State of New York.

The foregoing opinions are limited to the federal law of the United States of America and the law of the state of New York.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to this firm in the prospectus constituting a part of the Registration Statement under the heading “Validity of Securities” and in the prospectus supplement related thereto under the heading “Legal Matters” as counsel for Petrobras and PGF who have passed on the validity of the Securities being registered by the Registration Statement. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder. The opinions expressed herein are rendered on and as of the date hereof, and we assume no obligation to advise you or any other person, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinions expressed herein.

	Very truly yours,

- 3 -

3.	ASSUMPTIONS

For the purpose of rendering this opinion we have, except as expressly stated herein, without independent investigation or verification made the following assumptions:

3.1	Documents

3.1.1

All documents or instruments submitted to us as originals are authentic.

3.1.2

All documents submitted to us as scanned or photo static copies are complete and conform to original documents, and the originals of such copies are authentic.

The signatures (including endorsements), including any electronic signature (elektronische handtekening), any advanced electronic signature (geavanceerde elektronische handtekening) and any qualified electronic signature (gekwalificeerde elektronische handtekening) as meant in article 3 of Council Regulation (EU) No. 910/2014 of 23 July 2014 (eIDAS Regulation) and Section 3:15a of the Dutch Civil Code, of the natural persons purported to have signed the documents and instruments submitted to us (including all seals on the documents and instruments submitted to us) are genuine.

3.1.4

If an electronic signature (elektronische handtekening) is not a qualified electronic signature (gekwalificeerde elektronische handtekening), the signing method used is sufficiently reliable (voldoende betrouwbaar) taking into account the purpose for which that electronic signature was used and all other circumstances.

3.1.5

Under any applicable laws, the Base Indenture has not been terminated, rescinded, cancelled or nullified and is in full force and effect.

3.2

Incorporation, existence and corporate power

3.2.1

The Deed of Incorporation is a valid notarial deed (notariële authentieke akte), the contents thereof are correct and complete and there were no defects in the incorporation process of the Issuer (not appearing on the face of the Deed of Incorporation) on the basis of which a court might dissolve the Issuer or deem it never to have existed.

3.2.2

The Issuer has not been dissolved (ontbonden), merged (gefuseerd) involving the Issuer as disappearing entity, demerged (gesplitst), converted (omgezet) into another legal form either Dutch or foreign, subjected to an intervention, recovery or resolution measure, started or been subjected to a composition proceeding (onderhands akkoord), granted a moratorium of payments (surséance van betaling), declared bankrupt (failliet verklaard), subjected to any other insolvency proceedings listed in Annex A to the EC Council Regulation No. 2015/848 of 20 May 2015 on insolvency proceedings (recast) (as amended by Council Regulation from time to time), listed on the list referred to in article 2 (3) of Council Regulation (EC) No 2580/2001 of 27 December 2001, listed in Annex I to Council Regulation (EC) No 881/2002 of 27 May 2002 or listed and marked with an asterisk in the Annex to Council Common Position 2001/931 of 27 December 2001 relating to measures to combat terrorism, as amended from time to time, in any EU member state other than the Netherlands and has not passed a voluntary winding-up resolution and no petition has been presented or order made by a court for the bankruptcy (faillissement), dissolution (ontbinding) or moratorium of payments (surséance van betaling) of the Issuer and no statement concerning the Issuer has been submitted with the court registry regarding the preparation of a restructuring plan in accordance with section 370 paragraph 3 of the Dutch Bankruptcy Act (Faillissementswet) nor has a filing been made concerning the Issuer regarding a request with the court for the appointment of a restructuring expert in accordance with section 371 paragraph 1 of the Dutch Bankruptcy Act (Faillissementswet) (although not constituting conclusive evidence thereof, this assumption is supported by the contents of the Excerpt and the Checks (except for any proceedings for the restructuring of debts that have not been made public (besloten akkoordprocedure) or not yet been made public (openbare akkoordprocedure)).

- 4 -

3.2.3

The Articles are the articles of association of the Issuer in force on the date of the Resolutions, the date of the Supplemental Indenture, the date of the Prospectus Supplement, the date of the Notes and the date of this opinion letter (the “Relevant Date”) (although not constituting conclusive evidence thereof, this assumption is supported by the contents of the Excerpt).

The information in the Excerpt is true, accurate and complete on the Relevant Date (although not constituting conclusive evidence thereof, this assumption is supported by the Checks).

3.3

Corporate authorisations

3.3.1

The Resolutions have not been amended, revoked or declared void and remain in full force and effect and the statements made and confirmations given in the Resolutions are true, complete and correct on the Relevant Date.

3.3.2

It is in the corporate interest of the Issuer to enter into the Supplemental Indenture, to publish the Prospectus Supplement and to issue the Notes (although not constituting conclusive evidence thereof, this assumption is supported by (i) the text of the corporate objects clause in the Articles and (ii) the confirmation by the Management Board of the Issuer contained in the Board Resolution).

3.3.3

None of the managing directors (bestuurders) of the Issuer has any conflict of interest with the Issuer as meant in section 2:239 par. 6 of the Dutch Civil Code in respect of the Supplemental Indenture, its execution, the publication of the Prospectus Supplement, the issuance of the Notes, or the transactions contemplated thereby (although not constituting conclusive evidence thereof, this assumption is supported by the confirmation by the Management Board of the Issuer contained in the Board Resolution).

- 5 -

3.4

Execution

3.4.1

The Supplemental Indenture has been validly signed and duly authorised by the parties thereto (other than the Issuer).

3.4.2

The Power of Attorney remains in full force and effect on the date of the Shareholders Resolution and under any applicable law (other than Dutch law) validly authorises the attorney-in-fact to represent and bind the relevant grantor of the Power of Attorney for the purposes stated therein including the execution of the Shareholders Resolution.

3.5

Validity

3.5.1

Under any applicable laws (other than Dutch law), (i) the Supplemental Indenture constitutes the legal, valid and binding obligations of the parties thereto, and is enforceable against those parties in accordance with its terms and (ii) the choice of law and submission to jurisdiction made in the Supplemental Indenture is legal, valid and binding.

3.5.2

The performance by the Issuer of its obligations under the Supplemental Indenture is not illegal or ineffective under any jurisdiction (other than the Netherlands) that these obligations are to be performed under.

3.5.3

All requirements, formalities and other matters relating to the Supplemental Indenture under any applicable law (other than Dutch law) and in any jurisdiction (other than the Netherlands) in which any obligation under the Supplemental Indenture is to be performed have been complied with.

3.6

Regulatory

3.6.1

None of the parties to the Supplemental Indenture are subject to, controlled by or otherwise connected with a person, organization or country which is subject to United Nations, European Union, United States, United Kingdom, Dutch or any other sanctions implemented or effective under or pursuant to the Sanction Act 1977 (Sanctiewet 1977), the Economic Offences Act (Wet op de economische delicten), the General Customs Act (Algemene Douanewet), the Dutch Financial Supervision Act (Wet of het financieel toezicht), Regulations of the European Union or any other legislation.

3.6.2

The issuance and the offer of the Notes and the distribution of the Prospectus Supplement are made in accordance with the Prospectus Supplement in particular with the selling restrictions and legal requirements set out therein (including offering Notes in the European Economic Area only to qualified investors as defined in Regulation (EU) 2017/1129 of the European Parliament and of the Council of June 14, 2017 on the prospectus to be published when securities are offered to the public or admitted to trading on a regulated market, and repealing Directive 2003/71/EC).

- 6 -

3.6.3

Each Note will be duly executed, authenticated and delivered in accordance with the Supplemental Indenture and the Base Indenture.

OPINIONS

Based upon the foregoing and subject to the assumptions, qualifications, limitations and exceptions as set forth herein, and subject to any factual matters not disclosed to us in the course of our examination referred to above, we are at the date hereof, of the opinion that:

4.1

Corporate status

The Issuer was duly incorporated and is validly existing under the laws of the Netherlands as a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid).

4.2

Corporate power and authority

The Issuer has taken all necessary corporate action and has all corporate powers and authority to enter into the Supplemental Indenture, to publish the Prospectus Supplement and to issue the Notes and to perform its obligations thereunder.

4.3

No conflict with Articles and law

The entering into of the Supplemental Indenture, the publication of the Prospectus Supplement and the issuance of the Notes by the Issuer and the performance of its obligations thereunder do not (a) violate any Dutch law, or (b) violate, conflict with, or constitute a default under the Articles which would affect the enforceability of the Supplemental Indenture, the Prospectus Supplement and the Notes against the Issuer.

4.4

No consent

No authorisation, consent or approval of, notice to or filing or recording with any governmental or other public authority of or in the Netherlands is required for the entering into by the Issuer of the Supplemental Indenture or the performance by the Issuer of its obligations thereunder, the publication of the Prospectus Supplement, or the issuance of the Notes or the performance of its obligations thereunder, the absence of which would affect the enforceability of the Issuer’s obligations thereunder.

4.5

Choice of law

The choice of the laws of the State of New York to govern the contractual rights and obligations contained in the Supplemental Indenture is recognized under Dutch law and the courts of the Netherlands will observe and give effect to the choice of laws of the State of New York as the governing laws of the contractual rights and obligations contained in the Supplemental Indenture.

- 7 -

4.6

Submission to jurisdiction

The submission by the Issuer in the Supplemental Indenture to the non-exclusive jurisdiction of the courts of any federal court in the Borough of Manhattan, the City of New York, State of New York for any legal action, suit or proceedings arising out of or related to the Supplemental Indenture is recognized under Dutch law and will be given effect to by the Dutch courts.

4.7

No immunity

In proceedings taken in the Netherlands neither the Issuer nor any of its assets is immune from legal action or proceeding (including, without limitation, suit, attachment prior to judgment, execution or other legal process), except for assets located in the Netherlands which are destined for public services (goederen bestemd voor de openbare dienst) and the books and records of the Issuer.

QUALIFICATIONS

The opinions expressed above are subject to the following qualifications:

5.1

Dutch law

As Dutch lawyers we are not qualified or able to assess the true meaning and purport of the terms of the Supplemental Indenture, the Prospectus Supplement or the Notes under the applicable law and the obligations of the parties to the Supplemental Indenture, the Prospectus Supplement or the Notes and we have made no investigation of that meaning and purport. Our review of the Supplemental Indenture, the Prospectus Supplement or the Notes and of any other documents subject or expressed to be subject to any law other than Dutch law has therefore been limited to the terms of these documents as they appear to us on their face.

5.2

Insolvency

The enforcement of the rights and remedies set forth in the Supplemental Indenture may be affected or limited by any applicable bankruptcy (faillissement), moratorium of payments (surséance van betaling), composition proceeding (onderhands akkoord), any intervention, recovery or resolution measure by any regulatory or other authority or governmental body, other insolvency proceedings, fraudulent transfer (actio pauliana), claims based on tort (onrechtmatige daad), the Council Regulation (EC) No 2271/96 of 22 November 1996 on protecting against the effects of the extra-territorial application of legislation adopted by a third country, and actions based thereon or resulting therefrom, the European anti-money laundering directives, as implemented in the Netherlands in the Money Laundering and Terrorist Financing Prevention Act (Wet ter voorkoming van witwassen en financieren van terrorisme) and the Dutch Criminal Code (Wetboek van Strafrecht) and related legislation or other (Dutch or foreign) laws affecting the enforcement of creditor’s rights generally. The courts in the Netherlands may not always grant specific performance, whereas direct enforceability (reële executie) is normally only available in respect of obligations regarding the making of payments.

- 8 -

5.3

Corporate benefit / ultra vires

Any legal act entered into by a Dutch legal entity such as the Issuer may be nullified by such legal entity or the receiver in bankruptcy if it is ultra vires, i.e. falls outside the scope of such legal entity’s objects. A legal act may be ultra vires if (i) such legal act is not expressly allowed by the objects clause in such legal entity’s articles of association and could not be conducive to the realization of such objects and (ii) the other party was aware thereof or should be aware thereof without an independent investigation. All relevant circumstances of the case should be considered.

5.4

Powers of attorney

All powers of attorney, including powers of attorney expressed to be irrevocable, terminate by operation of law without notice upon the bankruptcy of the person issuing the power of attorney (the “Principal”), and will cease to be effective in case of a moratorium of payments of the Principal. Powers of attorney that are expressed to be irrevocable are not capable of being revoked insofar they extend to the performance of legal acts (rechtshandelingen) that are in the interest of either the attorney appointed by such power of attorney or a third party. However, such powers of attorney terminate by operation of law upon the bankruptcy of the Principal or, unless provided otherwise in such power of attorney, upon the death of, the commencement of legal guardianship over (onder curatelestelling) or the bankruptcy of the attorney or by notice of termination given by the attorney. A power of attorney does not affect the authority of the principal to perform actions within the scope of the power of attorney itself.

5.5

Dutch court proceedings

5.5.1

The submission by the Issuer to foreign courts is subject to the provisions of Council Regulation No. 1215/2012 of 12 December 2012 on jurisdiction and the recognition and enforcement of judgments in civil and commercial matters, amended by Council Regulation No. 542/2014 of 15 May 2014 and the rules and regulations promulgated pursuant thereto. The submission does not preclude that claims for provisional measures in summary proceedings and requests to levy pre-trial attachments (conservatoire beslagen) are brought before the competent courts of the Netherlands. The courts of the Netherlands may stay or refer proceedings if concurrent proceedings are brought elsewhere.

5.5.2

The choice of a foreign law as the law governing an agreement will generally be recognized and applied by the courts of the Netherlands, provided, however, that the Dutch courts may give effect to the mandatory rules of the laws of any country, including the Netherlands, with which the case in question has a close connection if and to the extent that pursuant to the laws of the latter country such mandatory rules must be applied, regardless of the law governing the agreement. When determining whether such mandatory rules must be applied the nature and intent of such rules are taken into account as well as the consequences that might ensue from the application or non-application of such rules. The law that otherwise would govern the Supplemental Indenture need not be applied by the Dutch courts, if it is obvious that the application thereof could not be reconciled with the public policy of the Netherlands or the European Union.

- 9 -

5.5.3

Regulation (EC) No 593/2008 of the European Parliament and of the Council of June 17, 2008 on the law applicable to contractual obligations (Rome I) does not apply to obligations arising under the Notes to the extent that (i) these obligations arise out of the negotiable character of the Notes or, (ii) the Notes constitute a "promissory note", "bill of exchange" or "cheque" within the meaning of the 1930 Convention on the Settlement of Certain Conflicts of Laws in Connection with Bills of Exchange and Promissory Notes or the 1931 Convention on the Settlement of Certain Conflicts of Laws in Connection with Cheques. Consequently we do not express an opinion regarding the choice of law with respect to obligations arising under the Notes to the extent that (i) these obligations arise out of the negotiable character of the Notes and/or, (ii) the Notes qualify as a promissory note, bill of exchange or cheque within the meaning of the respective conventions.

5.6

Regulatory

A person residing in the Netherlands may be designated by the Dutch Central Bank pursuant to the Act on financial foreign regulations 1994 (Wet financiële betrekkingen buitenland 1994), and if so designated, it has to file reports with the Dutch Central Bank for the benefit of the composition of the balance of payments for the Netherlands by the Dutch Central Bank. Failure to observe these requirements does however not affect the enforceability of the obligations of such person.

5.7

Trust

With respect to any trust to be created under the Supplemental Indenture pursuant to which the Issuer shall hold monies or other assets on trust, it is noted that any assets held by the Issuer pursuant to any such provision may form part of the Issuer's estate and therefore be subject to recourse by any creditor of the Issuer. However, pursuant to the Convention on the law applicable to trusts and their recognition of 1 July 1985, a trust created in accordance with the chosen law, will be recognised by the courts in the Netherlands, provided that the chosen law provides for trusts and the trust has been created voluntarily and is evidenced in writing. The courts in the Netherlands will, however, not be bound to recognise a trust of which the significant elements are more closely connected with states which do not provide for the institution of the trust.

5.8

Miscellaneous

5.8.1

Save as set out herein, nothing is to be taken to express an opinion in respect of any statement, representation or warranty made or given by or in respect of the Issuer in the Supplemental Indenture, the Prospectus Supplement and/or the Notes or any other document reviewed in connection with this letter of opinion.

- 10 -

5.8.2

The concept of a seal to be affixed to a document in order to make such document binding on the Issuer is not known or required under Dutch law.

5.8.3

The concept of delivery of a document in order to render a document valid, legally binding and enforceable is not known or required under Dutch law.

We express no opinion as to any law or regulation other than Dutch law as they are currently in force, and as generally interpreted and applied by the Dutch courts as at the date of this opinion, as appearing from published case law. We do not express any opinion with respect to any international law, including but not limited to the rules promulgated under or by any bi- or multilateral treaty or treaty organization, unless duly implemented in Dutch law, or to any Dutch tax law, regulatory law, Dutch or European competition law, data protection law or securitization law. For purposes of the opinions expressed in paragraph 4.3 (No conflict with Articles and law) and paragraph 4.4 (No consent) we have given regard only to those laws that we, having exercised customary professional diligence, would reasonably be expected to recognise as being applicable to an entity, transaction or agreement to which this letter of opinion relates. This opinion is related to Dutch law as it stands now and we do not assume any obligation to notify or inform you of any development subsequent to the date hereof that might render its contents untrue or inaccurate in whole or in part at such time. Furthermore, this opinion is strictly limited to the matters stated herein and may not be read as extending by implication to any matters not specifically referred to in it and we express no opinion on any matters of fact.

This opinion is construed, shall be governed by and have effect only in accordance with Dutch law. Further, the courts of Amsterdam, the Netherlands, shall have exclusive authority to rule upon any dispute relating to this opinion as far as this dispute may involve Heussen B.V.

In this opinion legal concepts are described in English terms and not by their original terms as described in the relevant national language. The concepts concerned may not be identical to the concepts described by the same English terms as they exist under the laws of other jurisdictions.
