2.4 No conflict

The entry into, delivery and performance of its obligations under the Indenture by each of the English Guarantors does not violate its memorandum and articles of association, or (ii) any existing laws of England and Wales applicable to companies generally.

The English Guarantors have duly executed and delivered the Indenture.

3. EXTENT OF OPINIONS

SCHEDULE 1

Assumptions

The opinions in this letter have been made on the basis of the following assumptions:

1. Genuine, authentic and complete documents/searches

(a) The genuineness of all signatures, stamps and seals on all documents, the authenticity and completeness of all documents submitted to us as originals, and the conformity to authentic original documents of all documents submitted to us as copies;

(b) that all documents, forms and notices which should have been delivered to the Companies Registration Office on behalf of, or relating to, each of the English Guarantors have been so delivered and the files of records maintained at the Companies Registration Office concerning each of the English Guarantors, as reproduced for us by our search agents, were complete, accurate and up to date at the time of the Searches, and have not since the time of the Searches been altered;

(c) that the contents of the Certificates are correct in all respects and the attachments to the Certificates are complete, accurate and up to date; and

(d) that none of English Guarantors has passed any new resolutions affecting, terminating, revoking or superseding the resolutions contained in the Certificates as reviewed by us.

2. Parties

(a) To the extent that the obligations of each of the English Guarantors under the Indenture may be dependent upon such matters, that with respect to any party (other than, to the extent expressly set out in the opinions in this letter in relation to the English Guarantors), such party:

(i) is duly organised, validly existing and in good standing (where such concept is legally relevant) under the laws of its jurisdiction of incorporation;

6

(ii) is in compliance, generally, with all applicable laws, rules and regulations to which it is subject, its constitutional documents and any judicial or administrative judgments, awards, injunctions or orders binding upon it or its property;

(iii) has the requisite organisational and legal power and authority to perform its obligations under all relevant documents;

(iv) is duly qualified to engage in the activities contemplated by all relevant documents and will not be in breach of any of its respective obligations under any document, contract, instrument or agreement as a result of its entry into and performance of its obligations under such documents;

(v) is authorised under all applicable laws of its jurisdiction and domicile (where not England and Wales) to submit to the jurisdiction of the English courts and, where not incorporated or domiciled in England and Wales, has validly submitted to such jurisdiction; and

(vi) has (or in the case of the Notes will have) validly authorised, executed and delivered all relevant documents;

(b) that, where a document is required to be delivered, each party to it has (or in the case of the Notes will have) delivered the same without it being subject to any escrow or other similar arrangement; and

(c) that, where any obligations entered into by the English Guarantor under the Indenture involve the giving of a guarantee or security in support of the obligations of a parent company, such obligations do not require the making of a provision (as contemplated by s.831(3) of the Companies Act 2006) which would result in any reduction in the English Guarantor’s net assets (or, to the extent they will result in a reduction, that reduction can be met out of the English Guarantor’s distributable reserves) or increase in the English Guarantor’s net liabilities.

3. Other documents or arrangements

(a) That the Indenture remains accurate and complete and has not been amended, terminated or otherwise discharged as at the date of this letter;

(b) the absence of fraud or mutual mistake of fact or law or any other arrangements, agreements, understandings or course of conduct or prior or subsequent dealings, amending, rescinding or modifying or suspending any of the terms of the Indenture or which would result in the inclusion of additional terms therein, and that the parties have acted in accordance with the terms of such agreements and documents; and

7

(c) that the Indenture has been entered into in good faith and on bona fide commercial terms and on arms’ length terms and for the purpose of carrying on each of the English Guarantors’ business and that there are reasonable grounds for believing that the giving of the guarantees in the Indenture by each of the English Guarantor will promote such English Guarantor’s success for the benefit of the members as a whole.

4. Representations and warranties

That all statements of fact and representations and warranties contained in or made in connection with any of the documents examined by us were true and correct as at the date given and are true and correct at today’s date and no fact was omitted therefrom which would have made any of such facts, representations or warranties incorrect or misleading.

5. Foreign laws

That there are no provisions of the laws, and there is no public policy, of any jurisdiction outside England which would be contravened by the execution and delivery of, or the performance of the obligations under, the Indenture and that, insofar as any obligation under, or action to be taken under, the Indenture is required to be performed or taken in any jurisdiction outside England, the performance of such obligation or taking of such action will not be illegal or unenforceable by virtue of the laws, or contravene any public policy, of that jurisdiction.

6. Filings, approvals, consents etc.

That no consents, approvals, authorisations, orders, licences, registrations, filings or similar formalities are required from any governmental or regulatory authority in connection with the execution, delivery and performance of the Indenture by any of the parties thereto or if such consents, approvals, authorisations, orders, licences, registrations, filings or similar formalities are required, these have been made or will be made within the prescribed time limits.

7. Insolvency

That none of the parties to the Indenture has taken any corporate or other action nor have any steps been taken or legal proceedings been started against any such party for the liquidation, winding up, dissolution, reorganisation or bankruptcy of, or for the appointment of a liquidator, receiver, trustee, administrator, administrative receiver or similar officer of, any such party or all or any of its or their assets (or any analogous proceedings in any jurisdiction) and none of the parties to the Indenture is unable to pay its debts as they fall due, is insolvent or has been dissolved or declared bankrupt.

SCHEDULE 2

Reservations

The opinions in this letter are subject to the following reservations:

1. Limitations of Searches

The Searches and the Enquiries are not conclusively capable of revealing whether or not insolvency proceedings have been commenced. We have not made any enquiry of any County Court as to whether a petition for the appointment of an administrator has been presented to, or an administration order made by, such County Court against the English Guarantor.

2. Insolvency

The opinions set out in this letter are subject to:

(a) any limitations arising from applicable laws relating to insolvency, bankruptcy, administration, reorganisation, liquidation or analogous circumstances; and

(b) an English court exercising its discretion under section 426 of the Insolvency Act 1986 (co-operation between courts exercising jurisdiction in relation to insolvency) to assist the courts having the corresponding jurisdiction in any part of the United Kingdom or any relevant country or territory.

3. Monetary obligations payable other than in Sterling

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

4. Matters of fact

We express no opinion as to matters of fact.
