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 on 1 February 2023 and is validly existing and in good standing under the laws of the Cayman Islands.

Authorised Share capital

(b) The authorised share capital of the Company is US$50,000 divided into 500,000,000 ordinary shares of a par value of US$0.0001 each (the Ordinary Shares).

Corporate Authorisation

(c) The Company has taken all requisite corporate action to authorise the issuance and sale of the Resale Shares under the Prospectus.

Valid Issuance of the Resale Shares

(d) The Resale Shares being proposed for resale by the Selling Shareholders have been validly issued, fully paid and non-assessable.

The Prospectus

(e) The statements contained in the Prospectus which pertain to Cayman Islands law, including without limitation, in the sections headed “Taxation - Cayman Islands Taxation”, “Description of Share Capital” and “Enforceability of Civil Liabilities”, 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.

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

(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 Prospectus, 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 Prospectus 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 of Companies in the Cayman Islands, 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 this opinion 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.

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 Prospectus and to the reference to our firm under the headings “Risk Factors”, “Enforceability of Civil Liabilities” and “Legal Matters” of the Prospectus. In giving such consent, we do not believe that we are “experts” within the meaning of such term used in the Securities Act or the rules and regulations of the Commission issued thereunder with respect to any part of the Prospectus, including this opinion as an exhibit or otherwise.

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

Yours faithfully

/s/ Ogier
