3 Opinions

Based upon, and subject to, the foregoing assumptions and the qualifications set out below, and having regard to such legal considerations as we deem relevant, we are of the opinion that:

3.1 The Company was incorporated in the British Virgin Islands under the BVI Business Companies Act on 4 July 2017, with company number 1949664, is a company limited by shares, is in good standing at the Registry of Corporate Affairs and is validly existing under the laws of the British Virgin Islands.

3.2 The Company is authorised to issue an unlimited number of shares of one class with no par value each.

3.3 When issued and paid for in the manner described in the the Registration Statement and in accordance with the Resolutions, the ordinary shares and the ordinary shares issuable pursuant to the debt securities, warrants, units and rights will be validly issued, fully paid and non-assessable. As a matter of British Virgin Islands law, a share is only issued when it has been entered in the register of members (or shareholders).

4 Qualifications

Except as explicitly stated herein, we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in any of the documents or instruments cited in this opinion or otherwise with respect to the commercial terms of the transactions the subject of this opinion.

In this opinion, the phrase “non-assessable” means, with respect to the Shares, that a shareholder shall not, solely by virtue of its status as a shareholder, be liable for additional assessments or calls on the 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).

To maintain the Company in good standing under the laws of the British Virgin Islands, annual filing fees must be paid to, and a copy of the Company’s register of directors filed with, the Registry of Corporate Affairs.

This opinion is provided solely for your benefit and use and may not be quoted in whole or in part or otherwise referred to or filed with any government agency or any other person without our prior express written consent, and no person other than the Company is entitled to rely on this opinion. Notwithstanding the foregoing, we hereby consent to filing of this opinion as an exhibit to the Registration Statement and to the reference to our name in the Registration Statement. In giving our consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.
