1 INTRODUCTION

I act as Dutch legal adviser (advocaat) to the Companies in connection with the Notes and the Registration.

Certain terms used in this opinion are defined in the Annex (Definitions).

2 DUTCH LAW

This opinion is limited to Dutch law in effect on the date of this opinion. It (including all terms used in it) is to be construed in accordance with Dutch law.

(ii) the form of the Notes, including the Guarantee, as included in the Supplemental Indenture;

(iii) the Registration Statement, including the Base Prospectus, and the Prospectus Supplement; and

In addition, I have obtained the following confirmations on the date of this opinion:

(g) In relation to each Company:

(i) confirmation through https://insolventies.rechtspraak.nl; and

(ii) confirmation through www.rechtspraak.nl, derived from the segment for EU registrations of the Central Insolvency Register;

in each case that the Company is not registered as being subject to Insolvency Proceedings.

I have not examined any document, and do not express an opinion on, or on any reference to, any document other than the documents referred to in this paragraph 3. My examination has been limited to the text of the documents and I have not investigated the meaning and effect of any document (or part of it) governed by a law other than Dutch law under that other law.

4 ASSUMPTIONS

I have made the following assumptions:

(a)

(i) Each copy document conforms to the original and each original is genuine and complete.

(b)

(i) All Board Regulations remain in force without modification.

(ii) Each Corporate Resolution has been duly adopted and remains in force without modification.

(ii) Its Agreements have been signed on behalf of each Company by one of its managing directors or by a person named as authorised representative in the Power of Attorney granted by it.

(d) All Notes have been or will have been signed on behalf of the Issuer, manually or, with the approval of the managing director concerned, in facsimile by the number of managing directors required by its articles of association.

(f) The Issuer is a wholly owned subsidiary of the Guarantor.

(g) The Issuer does not qualify as a bank (bank) within the meaning of the Wft.

5 OPINION

Based on the documents and confirmations referred to and assumptions made in paragraphs 3 and 4 and subject to the qualifications in paragraph 6 and any matters not disclosed to me, I am of the following opinion:

(a) Each Company has been incorporated and exists as a private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) (in the case of the Issuer) or a public limited liability company (naamloze vennootschap) (in the case of the Guarantor).

(ii) Each Company has taken all necessary corporate action to authorise its entry into and performance of its Agreements and, in the case of the Issuer, its issue and performance of the Notes.

(iii) Each Company has validly signed its Agreements and, in the case of the Issuer, the Notes.

(c) Each Company's entry into and performance of its Agreements and, in the case of the Issuer, its issue and performance of the Notes, do not violate Dutch law or its articles of association.

6 QUALIFICATIONS

This opinion is subject to the following qualifications:

(a) This opinion is subject to any limitations arising from (a) rules relating to bankruptcy, suspension of payments or emergency measures, (b) rules relating to foreign insolvency proceedings (including foreign Insolvency Proceedings), (c) other rules regulating conflicts between rights of creditors, or (d) intervention and other measures in relation to financial enterprises or their affiliated entities.

(b) Performance of an Agreement in violation of the Sanction Act 1977 (Sanctiewet 1977) will, and otherwise in violation of international sanctions may, violate Dutch law.

(c) To the extent that Dutch law applies, a legal act (rechtshandeling) performed by a person (including (without limitation) an agreement pursuant to which it guarantees the performance of the obligations of another person and any other legal act having a similar effect) may be nullified by any of its creditors, if (a) it performed the act without an obligation to do so (onverplicht), (b) the creditor concerned was prejudiced as a consequence of the act, and (c) at the time the act was performed both it and (unless the act was for no consideration (om niet)) the party with or towards which it acted, knew or should have known that one or more of its creditors (existing or future) would be prejudiced.

(d) To the extent that Dutch law applies, a power of attorney (or other authorisation to the same effect) can be made irrevocable only (i) insofar as it has been granted for the purpose of performing a legal act in the interest of the authorised person or a third party, and (ii) subject to any amendments made or limitations imposed by the courts on serious grounds (gewichtige redenen).

(e)

(i) An extract from the Trade Register does not provide conclusive evidence that the facts set out in it are correct. However, under the 2007 Trade Register Act (Handelsregisterwet 2007), subject to limited exceptions, a legal entity or partnership cannot invoke the incorrectness or incompleteness of its Trade Register registration against third parties who were unaware of the incorrectness or incompleteness.

(ii) A confirmation from an Insolvency Register does not provide conclusive evidence that an entity is not subject to Insolvency Proceedings.

(f) I do not express any opinion on:

(i) the validity, binding effect or enforceability of any Agreement, the Notes, the Current Report or the Registration Statement;
