2.1	Corporate Existence

2.5	Conflict with Laws and Articles of Association
	Neither the execution by the Guarantor of the Indenture nor the performance by the Indenture of its obligations thereunder conflicts with (i) the Articles of Association or (ii) any law of The Netherlands to which the Guarantor is subject which would make the Indenture null and void or subject the Indenture to nullification or avoidance.
3.	LIMITS OF OPINION
	This opinion is given only with respect to Dutch law in force as at the date hereof (excluding unpublished case law), excluding tax law, competition law and the law of the European Union to the extent not directly applicable in The Netherlands, except to the extent expressly opined on herein.

SCHEDULE 2
ASSUMPTIONS

The opinions in this Opinion Letter have been made on the following assumptions:

1. ORIGINAL AND GENUINE DOCUMENTATION

(a)	All signatures are genuine, all original documents are authentic and all copy documents are complete and conform to the originals.
(b)	The Indenture and Corporate Documents have been executed on the date specified in those documents by all parties to it in the form examined by us.

2. PARTIES OTHER THAN THE DUTCH OBLIGORS

(a)	Each party to the Indenture (other than the Guarantor) is duly incorporated and validly existing and has the capacity to enter into and to exercise its rights and to perform its obligations under the Indenture and there is nothing under applicable laws that would prevent this.
(b)	Each party to the Indenture (other than the Guarantor) has duly executed the Indenture.
(c)	Each of the Finance Parties is authorised to perform the transactions and services listed in Annex I to the EU Banking Co-ordination Directive (2006/48/EU) of 14 June 2006.

3. CORPORATE AUTHORITY OF THE DUTCH OBLIGORS

(a)

The sole managing director of the Guarantor does not have a conflict of interests with the Guarantor in respect of the Indenture that would preclude him from validly representing the Guarantor. Although not providing conclusive evidence this assumption is supported by the confirmation in the Board Resolution that the managing director does not have a conflict of interest.

(b)

The Indenture has been executed on behalf of the Guarantor by: (i) Mr A.G. de Vries (acting individually as authorised representative of Stichting TopCo, the sole managing director of the Guarantor) or (ii) by Messrs C. Kent Potter and Gerald A. O’Brien acting as attorney of the Guarantor pursuant to the Power of Attorney and the execution, delivery and performance of the Indenture is in the Guarantor’s corporate interest (vennootschappelijk belang) and conducive to the realisation of and useful in connection with the Guarantor’s corporate objects (doel).

CLIFFORD CHANCE LLP
ADVOCATEN SOLICITORS NOTARIS
BELASTINGADVISEURS

(c)	Under the laws governing the existence and extent of the Power of Attorney towards third parties (as determined pursuant to the rules of The Hague Convention on the Laws Applicable to Agency 1978), if other than Dutch law, such Power of Attorney authorised the Attorney to create binding obligations for the Guarantor towards the parties with whom such Attorney will act or has acted.
(d)	All parties entered into the Indenture for bona fide commercial reasons and on arms’ length terms.

4. INDENTURE

(a)	The Indenture constitutes the legal, valid and binding obligations of all parties thereto (other than the Guarantor) enforceable in accordance with its terms under the laws by which it is expressed to be governed and any other relevant laws.
(b)	The choice of law contained in the Indenture is a valid and binding selection and the submission by the Guarantor in the Indenture to the courts named therein is valid and binding under the laws by which the Indenture is expressed to be governed and any other relevant laws (except for Dutch law).
(c)	Insofar as any obligation of the Guarantor under the Indenture falls to be performed in any jurisdiction outside The Netherlands, such performance will not be illegal or ineffective under the laws of that jurisdiction.

5.	OTHER DOCUMENTS
	Save for those documents listed inSchedule 1(Documents and Enquiries), there is no other agreement, instrument or other arrangement between any of the parties to the Indenture which modifies or supersedes the Indenture.

SCHEDULE 3
RESERVATIONS

The opinions in this Opinion Letter are subject to the following qualifications.

1.	LIMITATIONS ARISING FROM INSOLVENCY LAW
	The opinions set out in this Opinion Letter are subject to any limitations arising from bankruptcy (faillissement), suspension of payments (voorlopige)surseance van betaling), voidable preference (Pauliana) and similar laws affecting the rights of creditors or secured creditors generally.
2.	ENFORCEABILITY

(a) The terms “enforceable”, “enforceability”, “valid”, “legal”, “binding” and “effective” (or any combination thereof) where used above, mean that the obligations assumed by the relevant party under the relevant document are of a type which Dutch law generally recognises and enforces; they do not mean that these obligations will necessarily be enforced in all circumstances in accordance with their terms; in particular, enforcement before the courts of The Netherlands will in any event be subject to:

(i)	the degree to which the relevant obligations are enforceable under their governing law (if other than Dutch law);
(ii)	the nature of the remedies available in the Dutch courts (and nothing in this opinion must be taken as indicating that specific performance or injunctive relief would be available as remedies for the enforcement of such obligations);
(iii)	the acceptance of such courts of jurisdiction and the power of such courts to stay proceedings if concurrent proceedings are being brought elsewhere;
(iv)	prescription or limitation periods (within which suits, actions or proceedings must be brought); and
(v)	the availability of defences such as, without limitation, set-off (unless validly waived), fraud, duress, error,force majeure, unforeseen circumstances, misrepresentation, undue influence, abatement and counter-claim.

(b) The validity and enforceability of the obligations of the Guarantor under the Indenture may be successfully contested by the Guarantor (or its receiver in

- 10 -

CLIFFORD CHANCE LLP
ADVOCATEN SOLICITORS NOTARIS
BELASTINGADVISEURS

	bankruptcy) on the basis of Article 2:7 Dutch Civil Code, if both (i) the execution of the Indenture is not within the scope of the objects of the Guarantor (doeloverschrijding), and (ii) the counterparty of the Guarantor under the Indenture knew or ought to have known (without enquiry) of this fact.
(c)	A public company with limited liability may not, with a view to the subscription or acquisition by third parties of shares in its share capital or depositary receipts thereof provide security (zekerheid stellen), grant loans (leningen verstrekken) provide guarantees (koersgarantie geven) or otherwise bind itself, whether jointly and severally or otherwise with or for third parties. This prohibition also applies to its subsidiaries.
(d)	The validity and enforceability of the obligations of the Guarantor under the Indenture may be successfully contested by its creditors if such obligation is prejudicial to the interests of such creditors (and the other requirements for voidable preference are met).
(e)	To the extent that any assets owned by the Guarantor have a public utility function, seizure of these assets is prohibited by virtue of Articles 436 and 703 Dutch Code of Civil Procedure. No attachments may be made on books with records required for the Guarantor’s business.

3.	POWER OF ATTORNEY
	Under Dutch law, each power of attorney or mandate, whether or not irrevocable, granted by the Guarantor in the Indenture and Corporate Documents, will terminate by operation of law and without notice upon its bankruptcy (faillissement) of the Guarantor and can only be effectively exercised with the co-operation of the court-appointed administrator (bewindvoerder) in the event of the Guarantor being granted a (preliminary) suspension of payments ((voorlopige)surseance van betaling). This qualification would also apply to the extent that the appointment by the Guarantor of a process agent were to constitute a power of attorney or a mandate.
4.	REGULATORY

(a) If a party to the Indenture is controlled by or otherwise connected with a person, organisation or (is itself resident in a country, which is the subject of United Nations, European Community or Netherlands sanctions, implemented, effective or sanctioned in The Netherlands under the Sanction Act 1977 (Sanctiewet 1977), the Economic Offences Act (Wet op de economische delicten), the Import and Export Act (In- en uitvoerwet) or the AFS, or is otherwise the target of any such sanctions, then the obligations of the

ADVOCATEN SOLICITORS NOTARIS

Guarantor to that party, or if that party is the Guarantor, the obligations of the Guarantor, under the Indenture may be unenforceable, void or otherwise affected.

(b)

The Guarantor may be appointed by, and in such case obliged to comply with all notification and registration requirements of, the Dutch Central Bank (De Nederlandsche Bank N.V.) in connection with all payments to be made by the Guarantor under the Indenture to or from non-residents of The Netherlands in accordance with the General Reporting Instructions 2003 (Rapportagevoorschriften betalingsbalansrapportages 2003) pursuant to the External Financial Relations Act 1994 (Wet financiële betrekkingen buitenland 1994), although a failure to perform any of these formalities will not adversely affect the validity, effectiveness, enforceability or admissibility in evidence of the Indenture or any payment made or to be made thereunder.

5. DUTCH COURT PROCEEDINGS

(a)	Notwithstanding a contractual provision to the contrary, a competent court in The Netherlands may assume jurisdiction (i) pursuant to Article 254 Dutch Code of Civil Procedure (Wetboek van Burgerlijke Rechtsvordering) in urgent matters, when, in view of the interests of the parties, provisional measures are required, (ii) in the context of an attachment against the Guarantor or any of its assets, and (iii) if the defendant enters appearance and does not contest the jurisdiction prior to defences relating to the merits and, if Section 1 (eerste afdeling) Title 1 Book 1 of the Dutch Code of Civil Procedure applies, there is a reasonable ground for jurisdiction of such Dutch court.
(b)	Pursuant to the Rome Convention, the relevant court in The Netherlands may give effect to (i) mandatory provisions of Dutch law irrespective of the choice of law made and no effect would be given to the choice of law in the Indenture to the extent that application of that law would be incompatible with the public policy in The Netherlands and (ii) mandatory rules of law of another jurisdiction with which the situation has a close connection, if and insofar as, under the law of the latter jurisdiction, those rules must be applied whatever the chosen law applicable to the Indenture.
(c)	The enforcement of the Indenture and of any foreign judgments in The Netherlands will be subject to the rules of civil procedure as applied by the courts in The Netherlands.
