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 is a company duly incorporated with limited liability under the BCA on 29 December 2023 and is validly existing and in good standing under the laws of the British Virgin Islands.

Maximum Number of Shares Authorised to Issue

(b)

Based solely on the Memorandum and Articles, the Company is authorised to issue (i) unlimited Class A Ordinary Shares with no par value each; and (ii) unlimited Class B Ordinary Shares with no par value each.

Corporate authorisation

(c)

The Company has taken all requisite corporate action to authorise the issuance and sale of the Shares under the Registration Statement and the Prospectus.

Class A Ordinary Shares

(d)

With respect to the Class A Ordinary Shares, when

(i)

the board of directors of the Company (the Board) has taken all necessary corporate actions to approve the issuance and allotment of the Class A Ordinary Shares, the terms of the offering of the Class A Ordinary Shares and any other related matters;

(ii)

the provisions of the memorandum and articles of association of the Company then in effect, the Registration Statement and any relevant prospectus supplement, and the applicable definitive purchase, underwriting or similar agreement approved by the Board have been satisfied and payment of the consideration specified therein has been made; and

(iii)

valid entry has been made in the register of members of the Company reflecting such issuance of Class A Ordinary Shares as fully paid shares and the subscription price of such Class A Ordinary Shares has been fully paid in cash or other consideration approved by the Board,

the Class A Ordinary Shares will be recognised as having been duly authorized and validly issued, fully paid and non-assessable.

Page 5 of 8

Taxation

(e)

No taxes, stamp duties, other duties, fees or charges are payable (by assessment, withholding, deduction or otherwise) to the government of the British Virgin Islands in respect of the Offering.

(f)

There is no withholding tax, capital gains tax, capital transfer tax, estate duty, inheritance tax, succession tax or gift tax in the British Virgin Islands and any dividends, interest, rents, royalties, compensations and other amounts paid by the Company are exempt from any taxation in the British Virgin Islands imposed under the British Virgin Islands Income Tax Ordinance (Cap 206). In particular, section 242 of the BCA provides the Company with a statutory exemption from all forms of taxation in the British Virgin Islands.

4	Limitations and Qualifications

4.1	We offer no opinion:

(a)

as to any laws other than the laws of the British Virgin 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 British Virgin 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 Registration Statement, 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 Registration Statement and any other agreements into which the Company may have entered or any other documents.

4.2

Under the BCA an annual fee must be paid in respect of the Company to the Registry of Corporate Affairs. Failure to pay the annual fees by the relevant due date will render the Company liable to a penalty fee in addition to the amount of the outstanding fees. If the license fee and/or any penalty fee remains unpaid from the due date, the Company will be liable to be struck off and dissolved from the Register of Companies in the British Virgin Islands.

Under the BCA, a copy of the Company’s register of directors which is complete must be filed by the Company at the Registry of Corporate Affairs. Failure to make this filing will render the Company liable to a penalty fee and if the filing is not made within the requisite time period or any penalty fee remains unpaid from the due date, the Company will be liable to be struck off and dissolved from the Register of Companies.

Under the BCA, an annual financial return, in the prescribed form, must be filed by the Company with its registered agent in respect of each year for which one is due within the timeframe prescribed by the BCA for that year (unless the Company is within one of the statutory exceptions to the obligation to file). Failure to make this filing when due will render the Company liable to a penalty fee and where the Company is liable to the maximum penalty and has not filed its annual return, the Company will be liable to be struck off and dissolved from the Register of Companies.

Page 6 of 8

Under the BCA, unless the Company is within one of the statutory exceptions to the obligation to file and is compliant with any conditions for the relevant exception(s) to apply, a copy of the Company’s register of members which is complete and certain prescribed beneficial ownership information for the Company must be filed by the Company at the Registry of Corporate Affairs. Failure to make these filings will render the Company liable to penalty fees and if the filings are not made within the requisite time period or any penalty fee remains unpaid from the due date, the Company will be liable to be struck off and dissolved from the Register of Companies.

For the purposes of this opinion “in good standing” means only that as of the date of this opinion it appears from our searches of the Public Records and on the basis of certain of the assumptions made in paragraph 2 being correct the Company is in good standing. We have made no enquiries into the Company’s good standing with respect to any other filings or payment of fees, or both, that it may be required to make under the laws of the British Virgin Islands other than the BCA. We have made no enquiries into whether the copy of the register of directors, the copy of the register of members or the Company’s beneficial ownership information filed at the Registry of Corporate Affairs matches the details set out on the Certificate of Incumbency or whether the annual return filed by the Company with its registered agent is in the prescribed form as required pursuant to the BCA.

4.3	The Public Records and our searches thereof may not reveal the following:

(a)

in the case of the Company Registry Records, details of matters which have not been lodged for registration or have been lodged for registration but not actually registered at the time of our search or notifications made to the Registrar of Corporate Affairs by its registered agent of any failure by any Company to file its register of directors, register of members, beneficial ownership information and/or annual return as required and within the time frame prescribed by the BCA;

(b)

in the case of the Court Records, details of proceedings which have been filed but not actually entered in the High Court Database at the time of our search;

(c)

whether an application for the appointment of a liquidator or a receiver has been presented to the High Court of the British Virgin Islands or whether a liquidator or a receiver has been appointed out of court, or whether any out of court dissolution, reconstruction or reorganisation of the Company has been commenced; or

(d)

any originating process (including an application to appoint a liquidator) in respect of the Company in circumstances where the High Court of the British Virgin Islands has prior to the issuance of such process ordered that such process upon issuance be anonymised (whether on a temporary basis or otherwise),

and the following points should also be noted:

(e)

the Court Records reflect the information accessible remotely on the High Court Database, we have not conducted a separate search of the underlying Civil Cause Book (the Civil Cause Book) or the Commercial Cause Book (the Commercial Cause Book) at the Registry of the High Court of the British Virgin Islands. Although the High Court Database should reflect the content of the Civil Cause Book and the Commercial Cause Book, neither the High Court Database nor the Civil Cause Book or Commercial Cause Book is updated every day, and for that reason neither facility can be relied upon to reveal whether or not a particular entity is a party to litigation in the British Virgin Islands;

Page 7 of 8

(f)

the High Court Database is not updated if third parties or noticed parties are added to or removed from the proceedings after their commencement; and

(g)

while it is a requirement under Section 118 of the Insolvency Act that notice of the appointment of a receiver be registered with the Registry of Corporate Affairs, however, it should be noted that failure to file a notice of appointment of a receiver does not invalidate the receivership but gives rise to penalties on the part of the receiver.

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 British Virgin 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 British Virgin Islands at the date of this opinion.

5.2	Unless otherwise indicated, a reference to any specific British Virgin Islands legislation is a reference to that legislation as amended to, and as in force at, the date of this opinion.

Reliance

We hereby consent to the filing of this opinion as an exhibit to the Form 6-K and to the reference to our firm under the headings “Enforceability of Liabilities” and “Legal Matters” of the Registration Statement and the Prospectus Supplement.

This opinion may be used only in connection with the Offering and while the Registration Statement is effective.
