(i) the minutes of a meeting of the managing board of BATNF held on 31 July 2017 reflecting resolutions approving, inter alia, the execution by BATNF of the Agreements and the performance of its obligations thereunder.

(3) BATHTN and BATNF are hereinafter collectively also referred to as the “Dutch Guarantors” and each a “Dutch Guarantor”. The Registration Statement, the Registration

Rights Agreement, the Indenture and the Supplemental Indenture are hereinafter collectively also referred to as the “Agreements”. The resolutions listed in paragraphs (2)(h) and (i) are hereinafter collectively also referred to as the “Resolutions”.

References to the Civil Code, the Bankruptcy Act, the Code of Civil Procedure, the Financial Supervision Act and any other Codes or Acts are references to the Burgerlijk Wetboek, the Faillissementswet, the Wetboek van Burgerlijke Rechtsvordering, the Wet op het financieel toezicht and such other Codes or Acts of the Netherlands, as amended. In this opinion, “the Netherlands” refers to the European part of the Kingdom of the Netherlands and “EU” refers to the European Union.

(4) In rendering this opinion we have assumed:

(a) the genuineness of all signatures on, and the authenticity and completeness of, all documents submitted to us as copies of drafts, originals or execution copies and the exact conformity to the originals of all documents submitted to us as photocopies or copies transmitted by facsimile or by electronic means;

(b) (i) the power, capacity and authority of all parties thereto other than the Dutch Guarantors to enter into and execute the Agreements; (ii) that the Agreements have been duly authorised by all parties thereto other than the Dutch Guarantors; and (iii) that the Agreements have been validly executed and delivered (where such concept is legally relevant) by each of the parties thereto (including but not limited to the Dutch Guarantors) under all applicable laws, including the laws by which the Agreements are expressed to be governed, other than the laws of the Netherlands;

(c) that any and all authorisations and consents of, or other filings with or notifications to, any public authority or other relevant body or person in or of any jurisdiction which may be required (other than under the laws of the Netherlands) in respect of the execution or performance of the Agreements have been or will be duly obtained or made, as the case may be;

(d) that the information set forth in the Extracts is complete and accurate on the date hereof and consistent with the information contained in the files kept by the Trade Register with respect to the Dutch Guarantors;

(e) that the Resolutions have not been annulled, revoked or rescinded and are in full force and effect as at the date hereof;

(f) that none of the Dutch Guarantors has been been declared bankrupt (failliet verklaard), granted suspension of payments (surseance van betaling verleend) or dissolved (ontbonden), nor has ceased to exist due to merger (fusie) or demerger (splitsing); although not constituting conclusive evidence, this assumption is supported by the contents of the Extracts and by our online search of the Central Insolvency Register of the courts in the Netherlands (Centraal Insolventieregister) on the date hereof, which did not reveal any information which would render this assumption to be untrue;

(g) that none of the insolvency proceedings listed in Annex A, as amended, to Regulation (EU) 2015/848 of the European Parliament and of the Council of 20 May 2015 on insolvency proceedings has been declared applicable to any of the Dutch Guarantors by a court in one of the member states of the EU (with the exception of Denmark), other than the Netherlands; although not constituting conclusive evidence, this assumption is supported by our online search of the section on EU Registrations of the Central Insolvency Register (Centraal Insolventieregister) on the date hereof, which did not reveal any information which would render this assumption to be untrue; and

(h) that none of the members of the managing board of any of the Dutch Guarantors has a conflict of interests within the meaning of section 2:239 of the Civil Code with the relevant Dutch Guarantor with respect to the Agreements or the transactions contemplated thereby.

(5) We have not investigated the laws of any jurisdiction other than the Netherlands. This opinion is limited to matters of the laws of the Netherlands as they presently stand. We do not express any opinion with respect to (i) any public international law or the rules of or promulgated under any treaty or by any treaty organisation, other than any provisions of EU law having direct effect, (ii) matters of competition law, and (iii) matters of taxation.

(6) Based upon and subject to the foregoing and to the further qualifications, limitations and exceptions set forth herein, and subject to any factual matters not disclosed to us and inconsistent with the information revealed by the documents reviewed by us in the course of our examination referred to above, we are as at the date hereof of the following opinion:

(a) each of the Dutch Guarantors has been duly incorporated and is validly existing under the laws of the Netherlands as a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) and has the necessary corporate capacity and power to enter into the Agreements and to exercise its rights and perform its obligations thereunder and under the Exchange Notes;

(b) all corporate action required to be taken by each of the Dutch Guarantors to authorise the execution of the Agreements by it or on its behalf and the performance of its obligations thereunder and under the Exchange Notes has been duly taken; and

(c) the Agreements have been duly executed on behalf of each Dutch Guarantor.

(7) This opinion is subject to the following qualifications:

(a) we express no opinion as to the accuracy of any representations given by the Dutch Guarantors or any other party (express or implied) under or by virtue of the Agreements;

(b) the opinions expressed above are limited by any applicable bankruptcy (faillissement), suspension of payments (surseance van betaling), insolvency, moratorium, reorganisation, liquidation, fraudulent conveyance, or similar laws affecting the enforceability of rights of creditors generally (including rights of set-off) in any relevant jurisdiction including but not limited to section 3:45 of the Civil Code and section 42 of the Bankruptcy Act concerning fraudulent conveyance, as well as by any sanctions or measures under the Sanctions Act 1977 (Sanctiewet 1977) or by EU or other international sanctions;

(c) no opinion is given as to whether any legal act (rechtshandeling) performed by any of the Dutch Guarantors in entering into the Agreements or exercising its rights or performing its obligations thereunder is not contrary to the corporate interest of the relevant Dutch Guarantor for purposes of section 2:7 of the Civil Code in which case the relevant legal act of the Dutch Guarantor might be held invalid and/or the obligations of the Dutch Guarantor thereunder might be held unenforceable in whole or in part; and

(d) the concepts of “trust” and of “delivery of documents” as known in common law jurisdictions are not known as such under the laws of the Netherlands.

(8) In this opinion, Netherlands legal concepts are expressed in English terms and not in their original Dutch terms. 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. This opinion is given by Stibbe N.V. and may only be relied upon under the express condition that (i) any issues of interpretation or liability arising hereunder will be governed by the laws of the Netherlands and will be brought exclusively before a court of the Netherlands, and (ii) such liability, if any, shall be limited to Stibbe N.V. only, to the exclusion of any of its directors, partners, employees, shareholders and advisors or its or their affiliates and to the aggregate of the amount paid under Stibbe N.V.‘s professional insurance in the particular instance and any applicable deductible payable by Stibbe N.V.

(9) We assume no obligation to update this opinion or to inform any person of any changes of law or other matters coming to our knowledge occurring after the date hereof which may affect this opinion in any respect. This opinion is addressed to you and given for your sole benefit for the purposes of the Agreements only and may not be disclosed or quoted to any person other than to your legal advisers or relied upon by any person or be used for any other purpose, without our prior written consent in each instance.

(10) We hereby consent to the filing of this opinion as exhibit to the Registration Statement and to the reference to our firm under the caption “Legal Matters” in the prospectus constituting a part of the Registration Statement. In giving such consent, we do not thereby admit or imply that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the United States Securities and Exchange Commission.

Yours faithfully,

Stibbe N.V.
