Notwithstanding any contractual submission to the exclusive or non-exclusive jurisdiction of specific courts, a Cayman Islands court has inherent discretion to stay or allow proceedings in the Cayman Islands against the Company under the Documents and any Securities if there are other proceedings in respect of the Documents and any Securities simultaneously underway against the Company in another jurisdiction.

This opinion is issued solely for your benefit and use in connection with the matter described herein and is not to be relied upon by any other person, firm or entity or in respect of any other matter.

4. OPINION

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 the Cayman Islands and, based on the Certificate of Good Standing, is in good standing as at the Certificate Date. Pursuant to the Companies Act (“Act”), a company is deemed to be in good standing if all fees and penalties under the Act have been paid and the Registrar of Companies has no knowledge that the company is in default under the Act.

4.2. Based solely on our review of the memorandum of association of the Company, the Company has an authorised share capital of US$50,000 divided into 50,000,000,000 shares of a nominal or par value of US$0.000001 each, of which 49,934,912,000 shall be designated as Class A ordinary shares of a nominal or par value of US$0.000001 each and 68,088,000 shall be designated as Class B ordinary shares of a nominal or par value of US$0.000001 each.

4.3. Upon the due issuance of Class A Ordinary Shares and payment of the consideration therefor, the Class A Ordinary Shares will be validly issued, fully paid and non-assessable (which term means when used herein that no further sums are required to be paid by the holders thereof in connection with the issue of such shares).

4.4. Upon due issuance of Securities (other than the Class A Ordinary Shares), such Securities will be validly issued and constitute the valid and binding obligations of the Company in accordance with the terms thereof.

4.5. The Selling Securities are validly issued, fully paid on non-assessable (which term when used herein means that no further sums are required to be paid by the holders thereof in connection with the issue of such shares).
