In giving this opinion we have relied upon the assumptions set forth in this paragraph 2 without having carried out any independent investigation or verification in respect of those assumptions:

(a) all original documents examined by us are authentic and complete;

(b) all copies of documents examined by us (whether in facsimile, electronic or other form) conform to the originals and those originals are authentic and complete;

(f) the Board Resolutions were duly passed in accordance with the then memorandum and articles of association of the Company and remain in full force and effect and each of the directors of the Company has acted in good faith with a view to the best interests of the Company and has exercised the standard of care, diligence and skill that is required of him or her in approving the Offering and no director has a financial interest in or other relationship to a party of the transactions contemplated by the Documents which has not been properly disclosed in the Board Resolutions;

(g) neither the directors nor the shareholders of the Company have taken any steps to appoint a liquidator of the Company, restructuring officer and no receiver has been appointed over any of the Company’s property or assets;

(k) no invitation has been or will be made by or on behalf of the Company to the public in the Cayman Islands to subscribe for any Ordinary Shares and none of the Ordinary Shares have been offered or issued to residents of the Cayman Islands; and

(l) the Register of Writs constitutes a complete and accurate record of the proceedings affecting the Company before the Grand Court as at the time we conducted our investigation of such Register.

3 Opinions

On the basis of the examinations and assumptions referred to above and subject to the limitations and qualifications set forth in paragraph 4 below, we are of the opinion that:

Corporate status

(a) The Company has been duly incorporated as an exempted company with limited liability and is validly existing and in good standing with the Registrar under the laws of the Cayman Islands.

Authorised share capital

(b) The authorised share capital of the Company is US$50,000 divided into 1,000,000,000 shares of par value US$0.00005 each.

Valid issuance of shares

(c) The Ordinary Shares, when issued and sold in accordance with the Registration Statement, the Memorandum and Articles and the duly passed Board Resolutions and once consideration set forth in the Registration Statement is paid in full, will be validly issued, fully paid and non-assessable. Once the register of members of the Company has been updated to reflect the issuance as fully paid, the shareholders recorded in the register of members will be deemed to have legal title to the Ordinary Shares set against their respective names.

Registration statement

(d) The statements contained in the Registration Statement in the section headed “Description of Share Capital”, “Enforceability of Civil Liabilities” and “Cayman Islands Taxation”, insofar as they purport to summarise the laws or regulations of the Cayman Islands, are accurate in all material respects and that such statements constitute our opinion.

4 Limitations and Qualifications

4.1 We offer no opinion:

(a) as to any laws other than the laws of the Cayman Islands, and we have not, for the purposes of this opinion, made any investigation of the laws of any other jurisdiction, and we express no opinion as to the meaning, validity, or effect of references in the Documents to statutes, rules, regulations, codes or judicial authority of any jurisdiction other than the Cayman Islands; or

Page 4 of 5

(b) except to the extent that this opinion expressly provides otherwise, as to the commercial terms of, or the validity, enforceability or effect of the Registration Statement, the accuracy of representations, the fulfilment of warranties or conditions, the occurrence of events of default or terminating events or the existence of any conflicts or inconsistencies among the Registration Statement and any other agreements into which the Company may have entered or any other documents.

4.2 Under the Companies Act (Revised) (Companies Act) of the Cayman Islands, annual returns in respect of the Company must be filed with the Registrar, together with payment of annual filing fees. A failure to file annual returns and pay annual filing fees may result in the Company being struck off the Register of Companies, following which its assets will vest in the Financial Secretary of the Cayman Islands and will be subject to disposition or retention for the benefit of the public of the Cayman Islands.

4.3 In good standing means only that as of the date of the Certificate of Good Standing the Company is up-to-date with the filing of its annual returns and payment of annual fees with the Registrar. We have made no enquiries into the Company’s good standing with respect to any filings or payment of fees, or both, that it may be required to make under the laws of the Cayman Islands other than the Companies Act.

4.4 We are not aware of any Cayman Islands authority as to when the courts would set aside the limited liability of a shareholder in a Cayman Islands company. Our opinion on the subject is based on the Companies Act and English common law authorities, the latter of which are persuasive but not binding in the courts of the Cayman Islands. Under English authorities, circumstances in which a court would attribute personal liability to a shareholder are very limited, and include: (a) such shareholder expressly assuming direct liability (such as a guarantee); (b) the company acting as the agent of such shareholder; (c) the company being incorporated by or at the behest of such shareholder for the purpose of committing or furthering such shareholder’s fraud, or for a sham transaction otherwise carried out by such shareholder. In the absence of these circumstances, we are of the opinion that a Cayman Islands’ court would have no grounds to set aside the limited liability of a shareholder.

4.5 In this opinion, the phrase “non-assessable” means, with respect to the Ordinary Shares of the Company, that a shareholder shall not, solely by virtue of its status as a shareholder, be liable for additional assessments or calls on the Ordinary Shares by the Company or its creditors (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstance in which a court may be prepared to pierce or lift the corporate veil).

5 Governing law of this opinion

5.1 This opinion is:

(a) governed by, and shall be construed in accordance with, the laws of the Cayman Islands;

(b) limited to the matters expressly stated in it; and

(c) confined to, and given on the basis of, the laws and practice in the Cayman Islands at the date of this opinion.

5.2 Unless otherwise indicated, a reference to any specific Cayman Islands legislation is a reference to that legislation as amended to, and as in force at, the date of this opinion.

6 Reliance

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the headings “Risk Factors”, “Enforceability of Civil Liabilities”, “Legal Matters” and “Taxation – Cayman Islands Taxation” of the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the U.S. Securities Act of 1933, as amended, or the Rules and Regulations of the Commission thereunder.

This opinion may be used only in connection with the offer and sale of the Ordinary Shares while the Registration Statement is effective.

Yours faithfully
