Non-conflict

No consents

Application of governing law

Submission to jurisdiction

Enforcement of judgments

A final and conclusive judgment in respect of the Agreements, the Indenture and the Notes obtained against the Company in a New York court would be recognised and enforced by the Luxembourg courts subject to the applicable enforcement procedure (as set out in the relevant provisions of the Luxembourg New Civil Procedure Code).

the foreign judgment must be enforceable in the country of origin,

the court of origin must have had jurisdiction both according to its own laws and to the Luxembourg conflict of jurisdictions rules,

the foreign proceedings must have been regular in light of the laws of the country of origin,

the rights of defence must not have been violated,

the foreign court must have applied the law which is designated by the Luxembourg conflict of laws rules, or, at least, the judgment must not contravene the principles underlying these rules,

the considerations of the foreign judgment as well as the judgment as such must not contravene Luxembourg international public policy,

the foreign judgment must not have been rendered as a result of or in connection with an evasion of Luxembourg law (“fraude à la loi”).

Any judgment awarded in the courts of Luxembourg may be expressed in a currency other than the euro. However, any obligation to pay a sum of money would be enforceable in Luxembourg in terms of the euro only.

QUALIFICATIONS

The opinions expressed herein are subject to, and may be affected or limited by, the provisions of any applicable bankruptcy (faillite), insolvency, liquidation, reprieve from payment (sursis de paiement), controlled management (gestion contrôlée), composition with creditors (concordat préventif de la faillite), reorganisation proceedings or similar Luxembourg or foreign law proceedings or regimes affecting the rights of creditors generally.

Notwithstanding a foreign jurisdiction clause, the Luxembourg courts would, in principle, have jurisdiction to order provisional measures in connection with assets or persons located in Luxembourg and such measures would most likely be governed by Luxembourg law.

International public policy means the fundamental concepts of Luxembourg law that the Luxembourg courts may deem to be of such significance so as to exclude the application of an (otherwise applicable) foreign law (deemed to be contrary in its results to such concepts). International public policy is a matter which is constantly evolving on the basis of the position of Luxembourg courts with respect to cases they hear. Accordingly, there are uncertainties as to what is considered as international public policy under Luxembourg law.

Claims may become barred under statutory limitation period rules and may be subject to defences of set-off or counter-claims. We express no opinion as to whether rights of set-off, including rights on close-out netting, are effective in a Luxembourg insolvency situation.

With respect to the opinions expressed in paragraph 4.6 above, the Luxembourg courts might not apply a chosen foreign law if that choice was not made bona fide and/or:

if it were not pleaded and proved; or

if such foreign law would be contrary to the mandatory provisions (lois impératives) or overriding mandatory provisions (lois de police) of Luxembourg law or manifestly incompatible with Luxembourg public policy; or

to the extent that relevant contractual obligations or matters fall outside of the scope of Regulation (EC) No 593/2008 of the European Parliament and the Council of 17 June 2008 on the law applicable to contractual obligations; or

if all other elements relevant to the situation are located in a country other than the jurisdiction of the chosen governing law, in which case the Luxembourg courts may apply the applicable mandatory provisions of such country; or

where the chosen governing law is not the law of an EU Member State, if all other elements relevant to the situation are located in one or several EU Member States, in which case the Luxembourg courts may apply applicable mandatory EU law provisions (as implemented in Luxembourg); or

where contractual obligations are to be or have been performed in another country where such performance is prohibited by overriding mandatory provisions; or

if a party is subject to insolvency proceedings, in which case the Luxembourg courts would apply the law of the jurisdiction where such insolvency proceedings have been duly opened (lex concursus) to the effects of such insolvency proceedings without prejudice to the exceptions provided for in the European Insolvency Regulation.

The corporate documents of, and relevant court orders affecting, a Luxembourg company (including, but not limited to, the notice of a winding-up order or resolution, notice of the appointment of a receiver or similar officer) may not be held at the Register immediately and there is generally a delay in the relevant document appearing on the files regarding the company concerned. Furthermore, it cannot be ruled out that the required filing of documents has not occurred or that documents filed with the Register may have been mislaid or lost. In accordance with Luxembourg company law, changes or amendments to corporate documents to be filed at the Register will be effective (opposable) vis-à-vis third parties only as of the day of their publication in the Luxembourg official gazette (Mémorial C, Recueil des Sociétés et Associations or RESA, Recueil électronique des sociétés et associations, as applicable) unless the company proves that the relevant third parties had prior knowledge thereof.

We do not express or imply any opinion in respect of a withholding tax that may become due or payable pursuant to the Luxembourg law of 23 December 2005 as amended introducing a withholding tax of 20% on payments of interest or similar income made or ascribed by a paying agent established in Luxembourg to or for the benefit of an individual beneficial owner who is resident of Luxembourg.

We express no tax opinion whatsoever in respect of the Company or the tax consequences of the transactions contemplated by the Agreements.

We express no opinion whatsoever on regulatory matters or on matters of fact or on matters other than those expressly set forth in this legal opinion, and no opinion is, or may be, implied or inferred herefrom.

We express no opinion as to whether the performance of the Agreements would cause any borrowing limits, debt/equity or other ratios possibly agreed with the tax authorities to be exceeded nor as to the consequences thereof.

We have not made any enquiry regarding, and no opinion is expressed or implied in relation to, the accuracy of any representation or warranty given by, or concerning, any of the parties to the Agreements or whether such parties or any of them have complied with or will comply with any covenant or undertaking given by them or the terms and conditions of any obligations binding upon them, save as expressly provided herein.

The rights and obligations of the parties under the Agreements may be limited by the effects of (i) criminal law measures, including without limitation criminal freezing orders, or (ii) public law sanctions or restraining measures taken from time to time under applicable laws, treaties or other instruments.

A search at the Register is not capable of conclusively revealing whether a (and the Certificates do not constitute conclusive evidence that no) winding-up resolution or petition, or an order adjudicating or declaring a, or a petition or filing for, bankruptcy or reprieve from payment (sursis de paiement), controlled management (gestion contrôlée), composition with creditors (concordat préventif de la faillite) or judicial liquidation (liquidation judiciaire) or similar action has been adopted or made.

As used in this legal opinion, the term enforceable means that the relevant rights and obligations are of a type which the Luxembourg courts do normally enforce. It does not mean that these obligations will necessarily be enforced in all circumstances in accordance with their respective terms, enforcement being subject to, inter alia, the nature of the remedies available in the Luxembourg courts, the acceptance by such court of jurisdiction, the discretion of the courts (within the limits of Luxembourg law), the power of such courts to stay proceedings, to grant grace periods, the provisions of Luxembourg procedure rules regarding remedies, enforcement measures available under Luxembourg law, mandatory provisions of Luxembourg law or principles of Luxembourg international public policy from time to time in force and the general principles of Luxembourg law in particular, the general principle of good faith performance.

Actions in Luxembourg courts must, in principle, be brought in the name of the principal not in the name of an agent of the principal.

Saved for the opinions expressed in paragraphs 4.6 and 4.7 above, we express no opinion whatsoever on the legal validity and the enforceability of the Agreements.

In the case of legal proceedings being brought before a Luxembourg court or production of the Agreements before an official Luxembourg authority, such Luxembourg court or official authority may require that the Agreements and/or any judgment obtained in a foreign court must be translated into French or German.

Punitive, treble or similar damages may not be enforceable in the Luxembourg courts.

This legal opinion is as of this date and we undertake no obligation to update it or advise of changes hereafter occurring. We express no opinion as to any matters other than those expressly set forth herein, and no opinion is, or may be, implied or inferred herefrom. We express no opinion on any economic, financial or statistical information (including formulas determining payments to be made) contained in the Agreements (or any document in connection therewith).

This legal opinion is given on the express basis, accepted by each person who is entitled to rely on it, that this legal opinion and all rights, obligations or liability in relation to it are governed by, and shall be construed in accordance with, Luxembourg law and that any action or claim in relation to it can be brought exclusively before the courts of Luxembourg.

The Addressee who is entitled to, and does, rely on this legal opinion agrees, by so relying, that, to the fullest extent permitted by law and regulation (and except in the case of wilful misconduct or fraud) there is no assumption of personal duty of care by, and such person will not bring any claim against, any individual who is a partner of, member of, employee of or consultant to Allen & Overy, société en commandite simple, Allen & Overy LLP or any other member of the group of Allen & Overy undertakings and that such person will instead confine any claim to Allen & Overy, société en commandite simple, Allen & Overy LLP or any other member of the group of Allen & Overy undertakings (and for this purpose “claim” means (save only where law and regulation applies otherwise) any claim, whether in contract, tort (including negligence), for breach of statutory duty, or otherwise).

Luxembourg legal concepts are expressed in English terms and not in their original French or German terms. The concepts concerned may not be identical to the concepts described by the same English terms as they exist under the laws of other jurisdictions. It should be noted that there are always irreconcilable differences between languages making it impossible to guarantee a totally accurate translation or interpretation. In particular, there are always some legal concepts which exist in one jurisdiction and not in another, and in those cases it is bound to be difficult to provide a completely satisfactory translation or interpretation because the vocabulary is missing from the language. We accept no responsibility for omissions or inaccuracies to the extent that they are attributable to such factors.

This document is signed on behalf of Allen & Overy, a société en commandite simple, registered on list V of the Luxembourg bar. The individual signing this document is a qualified lawyer representing this entity.
