Pursuant to the Registration Statement, the Company is registering under the Act an indeterminate amount of the Company's ordinary shares, $0.001 nominal value per share, issued or to be issued to the Selling Shareholder (as defined below) by the Company (the "Shares").

        The Shares are to be sold from time to time as set forth in the Registration Statement, the prospectus contained therein (the "Prospectus"), and the supplements to the Prospectus (the "Prospectus Supplements"). The Registration Statement also relates to the proposed sale of Shares by the selling shareholder identified in the Registration Statement (the "Selling Shareholder"), pursuant to Rule 415 under the Act, as set forth in the Registration Statement, the Prospectus and any Prospectus Supplement.

3.     Scope

        3.1   This opinion is limited to the laws of England and Wales as applied by the English courts as at the date of this letter. We have not investigated, and do not express or imply any opinion in relation to, the laws of any other jurisdiction and we do not express any opinion on European Community law as it affects any jurisdiction other than England and Wales.

        3.2   We expressly disclaim any responsibility to advise you of any development or circumstance of any kind, including any change of law or fact that may occur after the date of this letter that may affect the opinion expressed herein.

We express no opinion as to whether a foreign court (applying its own conflict law) will act in accordance with any agreement by the Company in connection with the issuance of the Shares as to jurisdiction and/or law. We express no opinion as to matters of fact.

        3.4   By giving this opinion we do not assume any obligation to notify you of changes in law following the date of this opinion which may affect the opinions expressed herein or to otherwise update this opinion in any respect.

        In giving this opinion we have assumed:

        4.1   the genuineness of all signatures, stamps and seals on all documents submitted to or examined by us (whether as originals or copies and whether in electronic form or otherwise);
