jurisdictions. In the event of a conflict or inconsistency, the relevant expression shall be deemed to refer only to the Netherlands legal concepts described by the English terms.

For the purposes of this opinion letter, we have assumed that at the Signing Date and as of today’s date:

a. all documents reviewed by us as originals are complete and authentic and the signatures thereon are the genuine signatures of the persons purporting to have signed the same, all documents reviewed by us as drafts of documents or as fax, photo or electronic copies of originals are in conformity with the executed originals thereof and such originals are complete and authentic and the signatures thereon are the genuine signatures of the persons purporting to have signed the same;

b. no defects such as vitiated consent, such as duress (bedreiging), fraud (bedrog), abuse of circumstances (misbruik van omstandigheden), set-off (verrekening) and error (dwaling), on the basis of which the Company might be dissolved by a court, attach to the incorporation of the Company (aan zijn totstandkoming kleven geen gebreken), and the Deed of Incorporation and the Articles of Association had respectively have been executed on the basis of a valid declaration of no objection (verklaring van geen bezwaar) by a civil law notary (notaris), who had the power and authority to execute such deeds and such deeds complied respectively comply with Netherlands Law (voldoen aan de eisen der wet);

c. the Indenture purporting to be signed by or on behalf of any party thereto has been duly authorised by all requisite corporate action of such party and has been validly signed on behalf of each party other than the Netherlands Company;

d. the Indenture constitutes, under any applicable law other than Netherlands Law, the legal, valid and binding obligations of the parties to the Indenture, enforceable against such parties in accordance with their terms and the choice of law clause and the jurisdiction clauses contained in the Indenture constitute under any applicable law, other than Netherlands Law, a legal, valid and binding choice of law for the law of the state of New York and submission to the jurisdiction of the courts of the state of New York; and

e. the Managing Director Certificate is in full force and effect and the factual statements made therein are true, complete and correct.

Based upon and subject to the foregoing and subject to the qualifications set forth herein and to any matters, documents or events not disclosed to us, we express the following opinions:

Due Execution

1. The Indenture has been validly entered into by the Netherlands Company.

Enforceability

2. The obligations of the Netherlands Company under Section 11 of the Indenture are enforceable against the Netherlands Company in the Netherlands in accordance with its terms.

The opinions expressed above are subject to the following qualifications:

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

B. The information contained in the Extract does not constitute conclusive evidence of the facts reflected in them.

C. Pursuant to Article 2:7 NCC, any transaction entered into by a legal entity may be nullified by the legal entity itself or its receiver in bankruptcy (curator) if the objects of such entity were transgressed by the transaction and the other party to the transaction knew or should have known this without independent investigation (wist of zonder eigen onderzoek moest weten). The Netherlands Supreme Court (Hoge Raad der Nederlanden) has ruled that in determining whether the objects of a legal entity are transgressed, not only the description of such objects in the articles of association (statuten) is decisive, but all (relevant) circumstances must be taken into account, in particular whether the interests of the legal entity were served by the transaction.

D. Pursuant to Article 2:207c NCC, a private company with limited liability may not grant loans (leningen verstrekken), provide security (zekerheid stellen), give a price guarantee (koersgarantie geven) or otherwise bind itself, whether jointly and severally or otherwise with or for third parties

(zich op andere wijze sterk maken of zich hoofdelijk of anderszins naast of voor anderen verbinden) with a view to (met het oog op) the subscription or acquisition by third parties of shares in its share capital or depository receipts. This prohibition also applies to its subsidiaries (dochtervennootschappen).

E. Without regard to any choice of law clause contained in the Indenture, the Netherlands courts:

a. in relation to the manner of performance and the steps to be taken in the event of defective performance, may have regard to the law of the country where performance of the agreement takes place;

b. may apply rules of Netherlands Law in a situation where they are mandatory irrespective of the law otherwise applicable to the agreement;

c. where they deem appropriate, may apply the mandatory rules of the law of another country with which the situation has a close connection, if and in so far as, under the law of the latter country, those rules must be applied whatever the law applicable to the agreement; and

d. may refuse to apply a rule of law otherwise applicable to the agreement, if such application is manifestly incompatible with the public policy (ordre public) of the Netherlands.

F. The phrase “enforceable in accordance with their terms” as used in opinion 2 above means that if any party to the Indenture brings an action (een rechtsvordering instellen) before a competent Netherlands Court seeking enforcement of the Indenture, such court should provide some remedy subject to the terms of the Indenture, the law of the state of New York or Netherlands Law, as the case may be, and other applicable law and with due observance of the provisions of the NCCP.

G. The enforceability of the obligations of the parties under the Indenture in the Netherlands may be limited or affected by:

a. any applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws or procedures now or hereinafter in effect, relating to or affecting the enforcement or protection of creditor’s rights generally; and

b. the provisions of fraudulent preference and fraudulent conveyance (Actio Pauliana) and similar rights available to receivers in bankruptcy or creditors in other jurisdictions. More

specifically, under the NCC and the Netherlands Bankruptcy Act, acts of fraudulent preference or fraudulent conveyance can be invalidated by a creditor of the debtor or by a trustee in bankruptcy of the debtor if the debtor carried out voluntary acts (i.e., acts without a legal obligation to do so), the results of which are detrimental to creditors of the debtor and if both the debtor and the opposite party knew, or should have known, that such acts would be detrimental to the creditors of the debtor. In case of voluntary acts by the debtor without consideration, or without at arm’s length consideration, knowledge of the fact that the acts are detrimental to the creditors by the opposite party is presumed. “Detrimental to creditors” means that the rights of the creditors of the debtor in fact are adversely affected, i.e. that the creditors actually receive less from the debtor as a direct result of the fraudulent preference or fraudulent conveyance. Whether a transaction is detrimental to creditors remains a factual matter. Under Netherlands law, the phrase “detrimental to creditors” is very broadly interpreted. For example, granting of collateral, increasing debt, reducing assets or transfer of assets from the debtor without (or without sufficient) consideration could be considered “detrimental to creditors”; and

c. claims based on tort (onrechtmatige daad);

d. sanctions implemented or effective in the Netherlands under the Sanctions Act 1977 (Sanctiewet 1977), the Economic Offences Act (Wet Economische Delicten) or European Community Regulations.

We hereby consent of the filing of this opinion as an exhibit to the Registration Statement and to the reference to us under the caption “Legal Matters” in the prospectus that is included in the Registration Statement.

Yours faithfully,

NautaDutilh N.V.
