Our role in respect of the entering into of the Documents (as defined below) by the Company has been limited to the issue of this opinion. We have not been involved in drafting or negotiating any documents or agreements cross-referred to in any the Documents. Accordingly, we assume no responsibility for the adequacy of any Document.

For the purposes of this opinion, we have examined, and relied solely upon, originals or electronic copies of the documents as listed below, but not any documents or agreements cross-referred to in any such document (the “Documents”):

2

The documents under d) through (including) i) are hereinafter collectively referred to as the “Corporate Documents”. The documents under d) and e) are hereinafter collectively referred to as the “Resolutions”.

Words importing the plural include the singular and vice versa. Where reference is made to the laws of The Netherlands, reference is made to the laws as in effect in the part of the Kingdom of The Netherlands that is located in Continental Europe (Europese deel van Nederland).

Except as stated herein, we have not examined any documents entered into by or affecting the Company or any corporate records of the Company and have not made any other enquiries concerning the Company.

In examining and describing the Documents and in giving the opinions stated below, we have, to the extent necessary to form the opinions given below, with your permission, assumed the following:

5

We have not investigated or verified and we do not express an opinion on the accuracy of the facts, representations and warranties as to facts set out in the Documents, and in any other document on which we have relied in giving this opinion and for the purpose of this opinion, we have assumed that such facts are correct.

We do not express an opinion on matters of fact, matters of law of any jurisdiction other than The Netherlands, nor on tax, anti-trust law, insider dealing, data protection, unfair trade practices, market abuse laws, sanctions or international law, including, without limitation, the laws of the European Union, except to the extent the laws of the European Union (other than anti-trust and tax law) have direct force and effect in The Netherlands. No opinion is given on commercial, accounting, tax or non-legal matters or on the ability of the parties to meet their financial or other obligations under the Documents.

6

Based on and subject to the foregoing (including the assumptions made above) and subject to any matters, documents or events not disclosed to us by the parties concerned and having regard to such legal considerations as we deem relevant, and subject to the qualifications listed below, we are of the opinion that:

Corporate Status

Capacity

Authorisation

Execution

According to the Company Excerpt, the board of managing directors of the Company consists of Adriaan Cornelis Konijnendijk (managing director A), Dennis Beets (managing director A), Paulus Cornelis Gerhardus van Duuren

7

(managing director A), Norman Joseph Buchanan (managing director B), Rosemary Hazel Hammond-West (managing director B) and Zie Ar Sing (managing director A) (jointly referred to as the “Board Members”)

Since the Board Resolution, which contains the Power of Attorney, is expressed to have been executed by the Board Members (excluding Zie Ar Sing as he was not appointed as managing director at the date of the Board Resolution), the Power of Attorney has been validly issued on behalf of the Company.

Thus, the execution of the Supplemental Indenture on behalf of the Company by means of the signature of an Attorney constitutes a due execution of the Supplemental Indenture on behalf of the Company.

The opinions expressed above are subject to the following qualifications:

Notwithstanding the generality of the previous paragraph, an Appointed Attorney maintains his powers in certain urgent cases during one year after the death of, or the commencement of legal guardianship over the Principal or a notice of termination by the Appointed Attorney.

8

Powers of attorney, which are expressed to be irrevocable, are not capable of being revoked and (unless the power of attorney provides otherwise) will not terminate upon the death of or the commencement of legal guardianship of the Principal insofar as they extend to the performance of legal acts (rechtshandelingen) which are in the interest of the Appointed Attorney or a third party. However, at the request of the Principal, an heir or a trustee of such person, the court may amend or cancel an irrevocable power of attorney for significant reasons.

In the event the Principal is granted a moratorium of payments (surseance van betaling), a power of attorney can only be exercised with the cooperation of the court-appointed administrator (bewindvoerder).

The Supreme Court of The Netherlands (Hoge Raad der Nederlanden) has ruled that in determining whether the objects of a company have been exceeded, the description of the object clause in the articles of association of the company alone is not decisive, but that all circumstances have to be taken into account. In particular, it should be taken into account whether the interests of the company were served by the transaction.

Most authoritative legal writers agree that acts of a company which are (a) within the objects clause as contained in the articles of association of the company and (b) in the actual interest of the company in the sense that such acts are conducive to the realisation of the objects of the company as laid down in its articles of association, do not exceed the objects of the company and therefore are not subject to nullification pursuant to Article 2:7 of the Dutch Civil Code, which view is supported by the Dutch Supreme Court.

9

In practice, the concept of ultra vires has rarely been applied in court decisions in The Netherlands. Only under exceptional circumstances have transactions been considered to be ultra vires and consequently have been annulled. Nullification of a transaction can result in (internal) liability of the managing directors toward the legal entity.

The issuing of the guarantees, is reflected in paragraph d. of article 3 of the objects clause (doelomschrijving) of the Articles of Association. However, the management of the Company must consider whether the issuing of the guarantees actually fulfils the material interests of the Company.

In issuing this opinion we do not assume any obligation to notify or to inform you of any developments subsequent to its date that might render its contents untrue or inaccurate in whole or in part at such time. This opinion letter:

The foregoing opinions are limited in all respects to and are to be construed and interpreted in accordance with the laws of The Netherlands as they stand at today’s date and as they are presently interpreted under published authoritative case law as at present in effect.

10

This letter may not be supplied, and its contents or existence may not be disclosed, to any person other than as an exhibit to (and therefore together with) the Registration Statement and may not be relied upon for any purpose other than the registration and the transactions to which the Indenture relates.

We consent to the incorporation by reference of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the caption “Legal Opinions” in the Prospectus. 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 U.S. Securities Act of 1933 or the rules and regulations of the SEC thereunder.

In this opinion the expressions “we”, “us”, “our” and like expressions should be construed accordingly.
