(a) will be subject to the laws from time to time in effect relating to bankruptcy, insolvency, liquidation, possessory liens, rights of set off, reorganisation, amalgamation, merger, moratorium, bribery, corruption, money laundering, terrorist financing, proliferation financing or any other laws or legal procedures, whether of a similar nature or otherwise, generally affecting the rights of creditors as well as applicable international sanctions;

(b) will be subject to statutory limitation of the time within which proceedings may be brought;

(c) will be subject to general principles of equity and, as such, specific performance and injunctive relief, being equitable remedies, may not be available;

(d) may not be given effect to by a Bermuda court if and to the extent they constitute the payment of an amount which is in the nature of a penalty; and

(e) may not be given effect by a Bermuda court to the extent that they are to be performed in a jurisdiction outside Bermuda and such performance would be illegal under the laws of that jurisdiction. Notwithstanding any contractual submission to the jurisdiction of specific courts, a Bermuda court has inherent discretion to stay or allow proceedings in the Bermuda courts.

3.2. “Non-assessability” is not a legal concept under Bermuda law, but when we describe the Common Shares and/or Preference Shares herein as being “non-assessable” we mean, subject to any contrary provision in any agreement between the Company and any one of its members holding any of the Common Shares and Preference Shares (but only with respect to such member), that no further sums are payable with respect to the issue of such shares and no member shall be bound by an alteration in the Constitutional Documents after the date upon which it became a member if and so far as the alteration requires such member to take or subscribe for additional Common Shares or Preference Shares or in any way increases its liability to contribute to the share capital of, or otherwise pay money to, the Company.

3.3. We have made no investigation of and express no opinion in relation to the laws of any jurisdiction other than Bermuda. This opinion is to be governed by and construed in accordance with the laws of Bermuda and is limited to and is given on the basis of the current law and practice in Bermuda. This opinion is issued solely for the purposes of the filing of the Registration Statement and the issuance of the Securities by the Company as described in the Registration Statement and is not to be relied upon in respect of any other matter.

4. OPINIONS

On the basis of and subject to the foregoing we are of the opinion that:

4.1. The Company is duly incorporated and existing under the laws of Bermuda in good standing (meaning solely that it has not failed to make any filing with any Bermuda governmental authority under the Companies Act 1981, or to pay any Bermuda government fee or tax, which would make it liable to be struck off the Register of Companies and thereby cease to exist under the laws of Bermuda).

4.2. Upon the due issuance of Common Shares and/or Preference Shares and payment of the consideration therefor, such Common Shares and/or Preference Shares will be validly issued, fully paid and non-assessable.

4.3. Upon the due issuance of (a) Debt Securities of any series; (b) Warrants; (c) Rights; (d) Depository Shares; (e) Purchase Contracts; and/or (f) Units, and payment of the consideration therefor (as may be required) , such Securities will be validly issued and (except in the case of any Equity Securities forming part of a Unit) will constitute valid and binding obligations of the Company in accordance with the terms thereof.

4.4. The Issued Shares are validly issued, fully paid and non-assessable.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to our firm under the caption “Legal Matters” in the prospectus forming a part of the Registration Statement. In giving such consent, we do not hereby admit that we are experts within the meaning of Section 11 of the Securities Act or that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the Rules and Regulations of the Commission promulgated thereunder.

Yours faithfully,
