4. OpinionS

Based upon, and subject to, the assumptions made above and the qualifications set out below and subject to any matters not disclosed to us, we are of the opinion that, under the laws of Luxembourg in effect, as construed and applied by the Luxembourg courts in published Luxembourg court decisions, on the date hereof:

4.1 Status

The Company is a private limited liability company (société à responsabilité limitée) formed for an unlimited duration and legally existing under the laws of Luxembourg.

4.2 Power and authority

The Company has the corporate power and authority to enter into and perform the obligations under the Opinion Documents.

4.3 Execution

The Opinion Documents have been duly authorised, executed and delivered on behalf of the Company.

5. Qualifications

The above opinions are subject to the following qualifications:

5.1 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.

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

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

5.4 We express no opinion whatsoever on the legal validity and enforceability of the Opinion Documents.

5.5 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, decision 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.

5.6 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 Official Gazette unless the company proves that the relevant third parties had prior knowledge thereof.

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

6. 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 Opinion Documents (or any document in connection therewith).

7. 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.

8. Any Addressee 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).

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 legal opinion is given to you in connection with the registration of the Notes with the SEC. We hereby consent to the inclusion of this legal opinion as an exhibit to the Registration Statement and the reference to our firm under the caption “Legal Matters” in the Prospectus which is filed as part of the Registration Statement. In giving this consent, we do not thereby admit that we are in a category of person whose consent is required under Section 7 of the Securities Act.

Yours faithfully,
