5. Opinions

 

We are of the opinion that:

 

5.1 Due incorporation, existence and status

5.2 Issuance of Securities

 

The issuance of the Advisory Warrants by the Company has been duly authorised. The 5,663,010 Class A Ordinary Shares currently issued and outstanding and held by the selling shareholders named in the Registration Statement have been duly authorised and are validly issued, fully paid and non-assessable. The 189,000 Class A Ordinary Shares to be issued by the Company to certain service providers upon the effectiveness of the Registration Statement and up to 260,317 Class A Ordinary Shares issuable upon exercise of the Advisory Warrants, in each case as contemplated by the Registration Statement, will be duly authorised for issue. When such Class A Ordinary Shares are issued by the Company upon effectiveness of the Registration Statement or upon exercise of the Advisory Warrants in accordance with their terms, as applicable, , such Class A Ordinary Shares will be validly issued, fully paid and non-assessable. As a matter of Cayman Islands law, a share is only issued when it has been entered in the register of members (shareholders).

There is currently no form of income, inheritance, gift, withholding, corporate or capital gains tax applicable to the Company in the Cayman Islands.

QUALIFICATIONS

 

1.In order to maintain the Company in good standing with the Registrar, annual fees must be paid and annual filings must be made with the Registrar within the prescribed periods.

 

2.Any issue of Securities or alteration to the status of the members of the Company will be void if made:

 

(a)without the consent of the court and after the date of the commencement of a winding up of the Company by the court; or

 

(b)without the consent of the liquidator and after the commencement of a voluntary winding up of the Company.

 

3.Under Cayman Islands law, the register of members (shareholders) is prima facie evidence of title to shares and this register would not record a third party interest in such shares. However, there are certain limited circumstances where an application may be made to a Cayman Islands court for a determination on whether the register of members reflects the correct legal position. Further, the Cayman Islands court has the power to order that the register of members maintained by a company should be rectified where it considers that the register of members does not reflect the correct legal position. As far as we are aware, such applications are rarely made in the Cayman Islands and for the purposes of the opinion given in paragraph ‎5.2, there are no circumstances or matters of fact known to us on the date of this opinion letter which would properly form the basis for an application for an order for rectification of the register of members of the Company, but if such an application were made in respect of the Securities, then the validity of such shares may be subject to re-examination by a Cayman Islands court.

 

4.In this Opinion, the phrase “non-assessable” means, with respect to the issuance of Securities, that a shareholder shall not, in respect of the relevant Securities and in the absence of a contractual arrangement or an obligation pursuant to the memorandum and articles of association to the contrary, have any obligation to make further contributions to the Company’s assets (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).
