3 Assumptions

We have assumed the following:

3.1 the genuineness of all signatures, stamps and seals of the persons purported to have signed the relevant documents and the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies;

3.2 all factual matters and statements relied upon or assumed in this Opinion are and were true and complete on the date of execution of the Registration Statement (and any documents in connection therewith);

3.3 the Articles, the Board Resolutions and the Secretary Certificate are in full force and effect, have not been amended, rescinded, revoked or declared null and void;

3.4 the information contained in the Secretary Certificate, the Excerpt and the RCS Certificate is true and accurate at the date of this Opinion;

3.5 the due compliance with all requirements (including, without limitation, the obtaining of the necessary consents, licences, approvals and authorisations, the making of the necessary filings, registrations and notifications and the payment of stamp duties and other taxes) under any laws (other than Luxembourg law) in connection with the valid issuance of the Debt Securities and the Guarantees (and any documents in connection therewith); and

3.6 there are no provisions in the laws of any jurisdiction outside Luxembourg, which would adversely affect, or otherwise have any negative impact on this Opinion.

4 Opinion

Based upon the assumptions made above and subject to the qualifications set out below and any factual matter not disclosed to us, we are of the following opinion:

4.1 the Company is a private limited liability company (société à responsabilité limitée), incorporated and validly existing under Luxembourg law for an unlimited duration.

2/4

4.2 The Company has the corporate power to issue the Debt Securities and the Guarantees and to perform the obligations expressed to be assumed by it thereunder as set out in the Registration Statement and, when the Debt Securities and/or the Guarantees are issued pursuant to duly adopted resolutions of the board of managers of the Company, and in accordance with duly authorised and executed and legally valid, binding and enforceable documentation, the Debt Securities and/or the Guarantees, as applicable, shall be validly issued.

5 Qualifications

This Opinion is subject to the following qualifications:

5.1 Our Opinion is subject to all limitations resulting from the application of Luxembourg public policy rules, overriding statutes and mandatory laws as well as to all limitations by reasons of bankruptcy (faillite), composition with creditors (concordat), suspension of payments (sursis de paiement), controlled management (gestion contrôlée), or the appointment of a temporary administrator (administrateur provisoire) and any similar Luxembourg or foreign proceedings affecting the rights of creditors generally (Insolvency Proceedings).

5.2 Our opinion that the Company validly exists is based on the Articles, the Excerpt and the RCS Certificate (which confirms in particular that no judicial decisions in respect of bankruptcy (faillite), composition with creditors (concordat), suspension of payments (sursis de paiement), controlled management (gestion contrôlée), or the appointment of a temporary administrator (administrateur provisoire) pertaining to the Company has been registered with the RCS). The Articles, the Excerpt and the RCS Certificate are, however, not capable of revealing conclusively whether or not the Company is subject to any Insolvency Proceedings.

We undertake no obligation to update it or to advise of any changes in such laws or their construction or application.
