3.1                               The Company is a public limited liability company (société anonyme) duly incorporated and validly existing under the laws of Luxembourg for an unlimited duration, with corporate power and authority under the laws of Luxembourg to own and operate its properties and to enter into and perform its obligations under each Opinion Document.

4.                                      QUALIFICATIONS

The foregoing opinion is subject to the following qualifications.

4.1                               Insolvency

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

4.2                               Bankruptcy, winding-up and similar actions

(1)                                 A search at the Register is not capable of conclusively revealing whether a (and the Certificate does 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) order or similar action has been adopted or made.

(2)                                 The corporate documents of, and the 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 may be a delay in the relevant notice appearing on the files regarding the relevant party. Further, 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.

4.3                               Luxembourg legal concepts and language differences

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 any are attributable to such factors.

5.                                      This opinion is as of this date and we undertake no obligation to update this opinion 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 Opinion Documents (or any document in connection therewith).

6.                                      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 only be brought before the courts of Luxembourg.

7.                                      Any person who is entitled to, and does, rely on this 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).

This opinion is given for your benefit only. It may not be relied upon by or disclosed to any other person, quoted, referred to or otherwise used (save as required by law) without our prior written consent, save that it may be included as exhibit 5.2 to the Registration Statement.

Yours faithfully
