1.2	We have conducted the following searches (together theSearches):

(b)

an enquiry made on 30 April 2012 at the office of the Viscount (the executive officer of the Jersey courts) in relation to the Parent Guarantor (theBankruptcy Search).

1.3	We have relied on a certificate of a director of the Parent Guarantor dated 30 April 2012 (theOpinion Certificate), a copy of which is attached to this opinion.

1.4

We have not examined for these purposes any other agreements or other documents (theOther Documents) to be entered into by the Parent Guarantor (including, without limitation, any supplemental indenture or any documents incorporated by reference in or otherwise referred to in the Indenture or the Registration Statement) and we offer no opinion on any such Other Document.

1.5	In this opinion a reference to a document having beenexecuted refers to it having been signed (or, as the case may be, sealed) by or on behalf of each party to it, dated and unconditionally delivered by or on behalf of each party to it.

2. Assumptions

We have assumed that:

2.1	each document examined by us (and any signature, initial, stamp or seal on it) is genuine and, where it is a copy, it conforms to the original document;

2.2	where an incomplete or uncompleted document or signature pages only have been supplied to us, the original document has been duly completed and is in substantially the same form as the last draft of that document examined by us;

2.3	the Opinion Certificate remains accurate;

2.4

each director of the Parent Guarantor (and each alternate) has disclosed to the Parent Guarantor any interests that, directly or indirectly, conflict or may conflict to a material extent with the interests of the Parent Guarantor and any of its subsidiaries with regard to the transactions and other matters recorded in the Board Extract and such disclosures are recorded in the minutes of the Directors’ Meeting, or previous board minutes, of the Parent Guarantor;

(a)

the capacity and power;

(b)

taken all the necessary action; and

(c)

obtained all the necessary agreements, approvals, authorisations, consents, licences, registrations or qualifications (whether as a matter of any law or regulation applicable to it or as a matter of any contract binding upon it),

to execute and perform its obligations under the Indenture;

2.8	the Indenture is legal, valid, binding and enforceable in accordance with its terms as a matter of all applicable laws other than Jersey law;

2.9

in causing the Parent Guarantor to enter into the Indenture, each of the directors of the Parent Guarantor was acting in good faith with a view to the best interests of the Parent Guarantor and was exercising the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances;

2.10	the Parent Guarantor is able to pay its debts as they fall due and will not become unable to do so by virtue of the execution of the Indenture or the performance of the transactions contemplated thereby and no steps have been taken or resolutions passed to wind up the Parent Guarantor;

2.11	the Parent Guarantor’s entry into, and the performance of its obligations under, the Indenture (including its obligations under the Guarantee) will not cause the Parent Guarantor to breach the limitation on borrowing contained in Article 83 (Power to borrow money) of its articles of association;

2.12	the Parent Guarantor, in entering into the Indenture, is acting as principal on its own behalf and not as an agent or trustee or in any other capacity;

2.15	the information disclosed by the Bankruptcy Search was at the time of the search (and remains) accurate and complete.

3. Opinion

Subject to the assumptions, observations, qualifications and limitations set out in this opinion and to matters not disclosed to us, we are of the opinion that, once the Registration Statement becomes effective under the Securities Act, and the Notes have been duly executed by the Issuer, duly authenticated in accordance with the terms of the Indenture and exchanged as contemplated in the Registration Statement, the obligations assumed by the Parent Guarantor under the Guarantee will constitute valid, legal, binding and enforceable obligations of the Parent Guarantor.

4. Qualifications and observations

Our opinion is subject to the following qualifications and observations:

4.1	This opinion is subject to all laws relating to bankruptcy, dissolution, insolvency, re-organisation, liquidation, moratorium or other laws of general application affecting the rights of creditors generally.

4.2

The termenforceable, when used in our opinion at paragraph 3 above, means that the obligations are of a type which the Jersey courts will enforce. It does not mean that those obligations will necessarily be enforced in all circumstances or in accordance with their terms. In particular, but without limitation:

(a)

enforcement may be prevented by statutory provisions relating to the setting aside of transactions at an undervalue, preferences and extortionate credit transactions and the disclaiming of onerous property;

(b)

enforcement may be limited by general principles of equity, for example equitable remedies such as specific performance and injunction are discretionary and may not be available where damages are considered to be an adequate remedy;

(c)

enforcement of obligations may be invalidated by reason of fraud, duress, misrepresentation, mistake or undue influence;

(d)

contractual obligations that are regarded as penalties may not be enforceable or may be liable to be reduced if found to exceed the maximum damages which the claimant could have suffered as a result of a breach of contract;

(e)

the Jersey courts will not enforce all or any obligations if they are illegal or contrary to public policy in Jersey or, where obligations are to be performed in a jurisdiction other than Jersey, if such performance would be illegal under the laws of that jurisdiction;

(f)

the Jersey courts may not enforce the terms of an agreement:

(i)

to the extent that the transactions contemplated by such terms conflict with or breach economic or other sanctions imposed by any treaty, law, order or regulation applicable to Jersey;

(ii)

for the payment or reimbursement of, or indemnity against, the costs of enforcement (actual or contemplated) or of litigation brought before the Jersey courts or where the Jersey courts have themselves made an order for costs;

(iii)

that provide for matters to be determined by future agreement;

(iv)

that would involve the enforcement of any foreign revenue, penal or other public laws;

(v)

that are in breach of any applicable exchange control regulations;

(vi)

that purport to exclude the jurisdiction of the Jersey courts;

(vii)

that provide that if terms are found to be illegal, invalid or unenforceable, the other terms of the agreement will remain enforceable; or

(viii)

to the extent that they have been frustrated by events happening after the execution of the agreement;

(g)

the Jersey courts may refuse to allow unjust enrichment;

(h)

provisions in an agreement (including in articles of association) that purport to fetter any statutory power in relation to a Jersey company may not be enforceable;

(i)

claims may become time barred or may be (or become) subject to rights and defences of counter-claim, estoppel, laches, set-off, waiver and similar defences;

(j)

the effectiveness of terms that release or exculpate any party from, or limit or exclude, a liability or duty otherwise owed or indemnify a person in respect of a loss caused by the act or omission of that person, may be limited by law;

(k)

where any party to an agreement is party to it in more than one capacity that party may not be able to enforce obligations purportedly owed by it to itself; and

(l)

a trust is invalid to the extent that it purports to apply directly to Jersey situate immovable property.

4.3	Security purported to be created by or pursuant to the Indenture over any property situate in Jersey may not be enforceable in Jersey.

4.4	Where a director fails, in accordance with the Companies (Jersey) Law 1991, to disclose an interest in a transaction entered into by a Jersey company or its subsidiary which conflicts or may conflict to a material extent with the interests of the company, the transaction is voidable.

4.5	The enforceability of a person’s obligations may be limited to the extent that such person successfully pleads either:

(a)

thedroit de discussion (whereby a guarantor may require the beneficiary of the guarantee to exhaust the assets of the principal debtor before making a claim against the guarantor); or

(b)

thedroit de division (whereby a co-obligor may require the person owed a joint obligation to make simultaneous claims in appropriate proportions upon all the co-obligors, thereby limiting its own liability),

unless the person has expressly waived such rights.

4.6

Despite any term of an agreement to the contrary, the Jersey courts may hold that:

(a)

any certificate, calculation, determination or designation of any party to the agreement is not conclusive, final and/or binding;

(b)

any person exercising any discretion, judgment or opinion under the agreement must act in a reasonable manner; and

(c)

any power conferred by the agreement on one party to require another party to execute such documents or do such things as the first party requires must be exercised reasonably.

4.7

The Jersey courts may stay or set aside proceedings where:

(a)

there is a more appropriate forum than Jersey where the action should be heard;

(b)

earlier or concurrent proceedings have been commenced elsewhere; or

(c)

there has already been a final determination of the matter by a court of competent jurisdiction.

4.8

The Company Search is not conclusively capable of revealing whether or not a shareholder resolution has been passed (or an order made) for:

(a)

the winding up or dissolution of the Parent Guarantor; or

(b)

the appointment of a liquidator in respect of the Parent Guarantor or any of its assets,

as notice of these matters is not required to be filed immediately or may not be filed within the time periods prescribed by law or, when filed, may not be entered on the public record of the Parent Guarantor immediately.

4.9

The Bankruptcy Search relates only to the making of a declaration that the property of the Parent Guarantor isen désastre. There is no formal procedure for determining whether the Parent Guarantor has otherwise become bankrupt (as defined in the Interpretation (Jersey) Law 1954).

5. Limitations

5.1

We have examined only the documents listed in paragraph 1.1 and have undertaken only the Searches for the purposes of issuing this opinion. We have not examined any term or document incorporated by reference in or otherwise referred to, whether in whole or part, in the Indenture and we offer no opinion on any such term or document.

5.2	We offer no opinion:

(a)

on the commercial terms of the Indenture or whether those terms reflect the intentions of the parties;

(b)

on any representation or warranty made or given in the Indenture;

(c)

as to whether the parties will be able to perform their obligations under the Indenture;

(d)

as to the title or interest of the Parent Guarantor to or in, or the existence of, any property or collateral the subject of the Indenture;

(e)

on any provision in the Indenture requiring written amendments and waivers of any of the provisions of the Indenture insofar as it suggests that oral amendments or waivers could not be agreed upon or granted by or between the parties or implied by the course of conduct of the parties; or

(f)

as to whether the acceptance, execution or performance of the Parent Guarantor’s obligations under the Indenture will result in the breach of or infringe any other agreement, deed or arrangement entered into by or binding on the Parent Guarantor other than the Parent Guarantor’s articles of association.

6. Jersey law

We have made no investigation and express no opinion with respect to the laws of any other jurisdiction. We assume no obligation to update the Addressee in relation to changes of fact or law which may have a bearing on the continuing accuracy of this opinion.

7. Benefit of opinion

This opinion is only addressed to, and for the benefit of, the Issuer. This opinion may not, without our prior written consent, be transmitted or disclosed to, or used or relied upon by, any other person (including, without limitation, any holder of, or holder of beneficial interests in, any Notes) or be relied upon for any other purpose whatsoever.
