all signatures, seals, dates, stamps and markings (whether on original or copy documents) are genuine;

each of the Good Standing Certificate, the Statutory Books and the Director’s Certificate is accurate and complete as at the date of this opinion;

all copies of the Registration Statement are true and correct copies and the Registration Statement conform in every material respect to the latest drafts of the same produced to us and, where the Registration Statement has been provided to us in successive drafts marked-up to indicate changes to such documents, all such changes have been so indicated;

the Board Resolutions 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 (as defined in the Board Resolutions) 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;

neither the directors of the Company or the shareholders of the Company have taken any steps to appoint a liquidator of the Company and no receiver has been appointed over any of the Company’s property or assets; and

there is no provision of the law of any jurisdiction, other than the Cayman Islands, which would have any implication in relation to the opinions expressed herein.

Opinions

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

The authorised share capital of the Company is US$50,000 divided 500,000,000 ordinary shares of par value US$0.0001 each.

The Resale Shares issued by the Company to Selling Securityholders and being proposed for resale by Selling Securityholders as contemplated by the Registration Statement have been duly authorised for issue and were validly issued, fully paid and non-assessable.

Selling Securityholders, upon due record of their respective names as the registered holders of the relevant Resale Shares as issued by the Company reflecting the issuance of the Resale Shares in the listed share register or register of members of the Company, are deemed to have the legal title to such Resale Shares under the Cayman Islands laws.

The statements contained in the Registration Statement in the section headed “Cayman Islands Taxation Considerations”, in so far 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.

Matters not covered

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;

except to the extent that this opinion expressly provides otherwise, as to the commercial terms of, or the validity, enforceability or effect of the documents reviewed (or as to how the commercial terms of such documents reflect the intentions of the parties), 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 documents and any other agreements into which the Company may have entered or any other documents; or

as to whether the acceptance, execution or performance of the Company’s obligations under the documents reviewed by us will result in the breach of or infringe any other agreement, deed or document (other than the Memorandum and Articles of Association) entered into by or binding on the Company.

Governing law of this opinion

This opinion is:

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

limited to the matters expressly stated in it; and

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

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.

Who can rely on this opinion

This opinion may be used only in connection with the resale of the Resale Shares by Selling Securityholders while the Registration Statement is effective. With the exception of your professional advisers (acting only in that capacity) and purchasers of the Resale Shares pursuant to the Registration Statement, it may not be relied upon by any person, other than persons entitled to rely upon it pursuant to the provisions of the Act, without our prior written consent.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. We also consent to the reference to this firm in the Registration Statement under the headings “Legal Matters” and “Enforceability of Civil Liability”.

Under the Companies Act, annual returns in respect of the Company must be filed with the Registrar of Companies, 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.

In good standing means only that as of the date of the Good Standing Certificate the Company is up-to-date with the filing of its annual returns and payment of annual fees with the Registrar of Companies. 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.

Our examination of the Register of Writs cannot conclusively reveal whether or not there is:

any current or pending litigation in the Cayman Islands against the Company; or

any application for the winding up or dissolution of the Company or the appointment of any liquidator or trustee in bankruptcy in respect of the Company or any of its assets,
