INTRODUCTION

SCOPE OF WORK

This opinion is limited to Dutch law. It (including all terms used in it) is to be construed in accordance with Dutch law.

As required by Dutch law, in preparing and issuing this opinion, we have observed the care which is to be expected from a reasonably proficient and reasonably acting Dutch opinion giver in similar circumstances (including our reputation) and accordingly:

we have performed the factual research set out in paragraph 3 and not any additional fact-finding actions (including not in respect of the correctness of the assumptions in paragraph 4 or the applicability of the qualifications in paragraph 6 except as expressly set out in it);

we have examined the text of the documents listed in paragraph 3 and not researched their meaning and effect beyond their semantic meaning to a Dutch opinion giver (including not their meaning and effect under any law other than Dutch law);

we have performed legal research into Dutch law reasonably likely to be relevant to this opinion and not any additional legal research (including into Dutch law not in effect on or prior to the date of this opinion); and

we do not express any opinion or view other than as expressly set out in paragraphs 5 and 6 (including not in respect of any document, or on any reference to a document, not listed in paragraph 3).

ASSUMPTIONS

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

Each Agreement has been signed by all parties in the form referred to in this opinion.

The Board Regulations remain in force without modification.

There is no works council (ondernemingsraad) the advice of which must be sought on the Company’s decision to guarantee the Notes.

Each party other than the Company has validly entered into each Agreement.

Each Power of Attorney remains in force without modification and no rule of law (other than Dutch law) which under the 1978 Hague Convention on the Law applicable to Agency applies or may be applied to the existence and extent of the authority of any person authorised to sign any Agreement on behalf of the Company under a Power of Attorney, adversely affects the existence and extent of that authority as expressed in that Power of Attorney (including, whether or not expressed, to sign by electronic signature).

OPINION

The Company has been incorporated and exists as a public limited liability company (naamloze vennootschap).

The Company has the corporate power to enter into and perform each Agreement.

The Company has taken all necessary corporate action to authorise its entry into and performance of each Agreement.

The Company has validly signed each Agreement.

The Company does not require any governmental licence, dispensation, recognition or other consent for its entry into and performance of any Agreement.

There are no governmental registration, filing or similar formalities required to ensure the validity and binding effect on and enforceability against the Company of any Agreement.

The Company’s entry into and performance of each Agreement do not violate Dutch law or its Articles of Association.

The choice of New York law as the governing law of the Guarantees and the Base Indenture is recognised.

Dutch law does not restrict the validity and binding effect on and enforceability against the Company of each Agreement.

The validity and binding effect on and enforceability against the Company of the submission to the jurisdiction of the New York Courts in the Base Indenture:

under Dutch private international law are likely governed by New York law; and

are not restricted by Dutch law.

The validity and binding effect on and enforceability against the Company of the appointment by it in the Base Indenture of an agent for service of process:

is governed by the law designated by New York private international law; and

is not restricted by Dutch law.

A judgment in a civil or commercial matter rendered by a New York Court cannot be enforced in the Netherlands. However, if a person has obtained a final judgment without appeal in such a matter rendered by a New York Court which is enforceable in New York and files his claim with a Dutch court with jurisdiction, the Dutch court will generally recognise and give effect to the judgment insofar as it finds that (A) the jurisdiction of the court has been based on an internationally generally accepted ground, (B) proper legal procedures have been observed, (C) the judgment does not contravene Dutch public policy, and (D) the judgment is not irreconcilable with a judgment of a Dutch court or an earlier judgment of a foreign court that is capable of being recognised in the Netherlands.

The Company is not entitled to immunity from legal proceedings nor are its assets immune from execution.

In a Dutch court, the creditor of a claim expressed in a foreign currency may seek an order for payment at his option in that foreign currency or in the Dutch currency.

QUALIFICATIONS

This opinion is subject to any limitations arising from (i) rules relating to Dutch Insolvencies, (ii) rules relating to foreign insolvency or composition or restructuring proceedings (including foreign Insolvency Proceedings), (iii) other rules regulating conflicts between rights of creditors, or (iv) resolution, intervention and other measures in relation to financial enterprises or their affiliated entities.

The recognition of New York law as the governing law of the Guarantees and the Base Indenture:

will not prejudice the provisions of the law of the European Union (where appropriate as implemented in the Netherlands) which cannot be derogated from by agreement if all elements relevant to the situation at the time when each of the Guarantees and the Base Indenture was entered into (other than the choice of New York law as the governing law of such Agreement) are located in one or more Member States of the European Union;

will not restrict the application of the overriding provisions of Dutch law; and

will not prevent effect being given to the overriding provisions of the law of a jurisdiction with which the situation has a close connection;

will not prevent the application of New York law being refused if it is manifestly incompatible with Dutch public policy (ordre public); and

will not prevent regard being had to the law of the jurisdiction in which performance takes place in relation to the manner of performance and the steps to be taken in the event of defective performance.

The binding effect and enforceability of the submission to the jurisdiction of the New York Courts in the Base Indenture are subject to limited exceptions, including any exceptions applicable under the Brussels I-bis Regulation or the Lugano Convention.

Under the Brussels I-bis Regulation, a choice of court agreement that (i) provides for a choice of court in the European Union, and (ii) permits a party to bring proceedings before another court, is valid insofar as (A) the other court is a court in the European Union or a state party to the Lugano Convention, and (B) the agreement identifies objective factors which are sufficiently precise to enable the

Enforcement in the Netherlands of each Agreement and of foreign judgments is subject to Dutch rules of civil procedure.

The Sanction Act 1977 (Sanctiewet 1977) or international sanctions may affect whether (i) the Company’s entry into and performance of each Agreement violates Dutch law, and (ii) each Agreement is valid, binding and enforceable.

In respect of proceedings in a Dutch court for the enforcement of each Agreement, the appointment of a process agent pursuant to Section 1.14(1) of the Base Indenture may be without effect.

In proceedings in a Dutch court for the enforcement of any Agreement, the court may mitigate amounts due in respect of litigation and collection costs.

Any trust to which the 1985 Convention on the Law applicable to Trusts and their Recognition (the “Trust Convention”) applies, will be recognised subject to the Trust Convention. Any trust to which the Trust Convention does not apply may not be recognised.

If a legal act (rechtshandeling) performed by a Dutch legal entity (including (without limitation) an agreement pursuant to which it guarantees the performance of any of another person’s obligations and any other legal act having a similar effect) is not in the entity’s interest, the act may (i) exceed the entity’s corporate or other power, (ii) violate its articles of association, and (iii) be nullified by it if the other party or parties to the act knew or should have known without investigation that the act is not in the entity’s interest.

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.

An extract from the Trade Register does not provide conclusive evidence that the facts set out in it are correct. However, under

A confirmation from the Central Insolvency Register does not provide conclusive evidence that an entity is not subject to a Dutch Insolvency or foreign Insolvency Proceedings (also because they are not all registered).

We do not express any opinion on:

competition (including state aid) matters;

the validity of any assignment or transfer pursuant to each of the Agreements or any other in rem matters; and

tax matters.
