3 Opinion

Based upon, and subject to, the foregoing and subject to the qualifications set out in this letter and any matter not disclosed to us, we are of the opinion that so far as the laws of Ireland are concerned:

(a) the Company is a public limited company, duly incorporated and existing under the laws of Ireland; and

(b) the guarantee of the New Notes provided for in the Indenture has been duly authorised by the Company and constitutes a legal, valid and binding obligation of the Company.

4 Qualifications

The opinions set forth in this Opinion letter are given subject to the following qualifications:

(a) A search at the CRO is not capable of revealing whether, or not, a winding-up petition or a petition for the appointment of an examiner has been presented in respect of the company concerned. While notice of a winding-up order or resolution, notice of an order for the appointment of an examiner and notice of the appointment of a receiver may be revealed by a search at the CRO, any such notice may not be filed at the CRO immediately or at all, and, if filed there may be a delay in the relevant notice appearing on the file of the company concerned; therefore, our searches at the CRO may not have revealed such matters.

(b) A search at the Index of Petitions and Winding-up Notices maintained at the Central Office of the High Court of Ireland is not capable of revealing whether, or not, a receiver has been appointed in respect of the company concerned. While notice of the presentation of a winding-up petition or a petition for the appointment of an

examiner may be revealed by a search at the Index of Petitions and Winding-up Notices maintained at the Central Office of the High Court of Ireland, any such notice may not be filed immediately or at all, and, if filed there may be a delay in the relevant notice appearing on the Index of Petitions and Winding-up Notices; therefore, our searches at the Index of Petitions and Winding-up Notices maintained at the Central Office of the High Court of Ireland may not have revealed such matters

(c) The terms “legal, valid and binding” as used in paragraph 3(b) above, means that the obligations assumed by the Company under the Indenture are of a type which the courts of Ireland will treat as legal, valid and binding and enforceable. It does not mean that these obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular, enforcement of the Company’s obligations under the Indenture may be:

(i) limited by general principles of equity, in particular, equitable remedies (such as an order for specific performance or an injunction) which are discretionary and are not available where damages are considered to be an adequate remedy;

(ii) subject to any limitations arising from examinership, administration, bankruptcy, insolvency, moratoria, receivership, liquidation, reorganisation, court scheme of arrangement, arrangement and similar laws affecting the rights of creditors;

(iii) limited by the provisions of the law of Ireland applicable to contracts held to have been frustrated by events happening after their execution;

(iv) invalidated if and to the extent that performance or observance arising in a jurisdiction outside Ireland would be unlawful, unenforceable, or contrary to public policy or to the exchange control regulations under the law of such jurisdiction;

(v) invalidated by reason of fraud; and

(vi) barred under the Statute of Limitation Acts 1957 of Ireland (as amended) or may be or become subject to the defence of set-off or counterclaim

(d) As regards jurisdiction, the courts of Ireland may stay proceedings if concurrent proceedings are being brought elsewhere.

(e) The Companies Act prohibits certain steps being taken except with the leave of the court against a company after the presentation of a petition for the appointment of an examiner. This prohibition continues if an examiner is appointed for so long as the examiner remains appointed (maximum period of one hundred days or such period as the court in question may determine). Prohibited steps include steps taken to enforce any security over the company’s property, the commencement or continuation of proceedings or execution or other legal process or the levying of distress against the company or its property and the appointment of a receiver.

(f) Under the provisions of the Companies Act, an examiner can be appointed on a petition to the Circuit Court, if certain criteria are met. It is not possible for anyone other than a party to the relevant proceedings or the solicitors on record for such

parties to inspect the Circuit Court files to ascertain whether a petition for the appointment of an examiner has been made in the Circuit Court, and we have made no searches or enquiries in this regard in respect of the Company.

(g) A contractual provision conferring or imposing a remedy or an obligation consequent upon default may not be enforceable if it were construed by an Irish court as being a penalty, particularly if it involved enforcing an additional pecuniary remedy (such as a default or overdue interest) referable to such default and which does not constitute a genuine and reasonable pre-estimate of the damage likely to be suffered as a result of the default in payment of the amount in question or the termination in question; further, recovery may be limited by laws requiring mitigation of loss suffered.

(h) An Irish court may not give effect to an indemnity given by any party in the Indenture to the extent it is in respect of legal costs incurred by an unsuccessful litigant.

(i) In the event of any proceedings being brought in an Irish court in respect of a monetary obligation expressed to be payable in a currency other than euro, an Irish court would have the power to give a judgment to pay a currency other than euro, it may decline to do so in its discretion and an Irish court might not enforce the benefit of currency conversion or indemnity clauses and, with respect to a bankruptcy, liquidation, insolvency, reorganisation or similar proceeding, the law of Ireland may require that all claims or debts are converted into euro at an exchange rate determined by the court as at a date related thereto, such as the date of commencement of a winding up

(j) A determination or calculation of any party to the Indenture stated in the Indenture to be conclusive may be held by the courts of Ireland not to be final, conclusive or binding.

(k) The effect of terms, if any, in the Indenture excusing a party from a liability or duty otherwise owed are limited by law.

(l) Where a party is vested with a discretion or may determine a matter in his or its opinion, the law of Ireland may require that such discretion is exercised reasonably or that such opinion is based upon reasonable grounds.

(m) The enforceability of any provision as to severability may be determined by the courts of Ireland at its discretion.

(n) No opinion is expressed on the irrevocability of any power of attorney.

(o) An Irish court may not give effect to any provision of the Indenture which provides for a matter to be determined by future agreement or negotiation.

(p) A right of set-off provided for in a contract or another document may not be enforceable in all circumstances.

Yours faithfully
