3.1 For the purposes of giving this opinion, we have with your permission assumed (and relied upon these assumptions):

3.1.1 the conformity to the originals of all documents supplied to us as drafts, certified, photocopied, conformed or facsimile copies and the authenticity and completeness of the originals of such documents, and the authenticity and completeness of all documents supplied to us as originals;

3.1.2 the genuineness of all signatures and seals on the documents and instruments submitted to us for the purposes of this opinion and where we have been provided with only signature pages of documents, that the original signed versions of such documents will not differ from the last version of the full documents provided to us;

3.1.3 that there are no provisions of the laws of any jurisdiction outside Guernsey which would have any implication for the opinions we express and that, insofar as the laws of any jurisdiction outside Guernsey may be relevant, such laws have been or will be complied with (including without limitation, the obtaining of all necessary consents, licences, registrations, approvals and filings);

Page 2 / 15 March 2024

3.1.4 that the information and documents disclosed by our searches of the Public Records in Guernsey referred to in paragraph 2.4 above are accurate as at the date hereof and there is no information or document which had been delivered for registration, or which is required by the laws of Guernsey to be delivered for registration, which was not included in the Public Records;

3.1.5 that all factual representations, warranties and statements made or agreed to by the parties to the Registration Statement are true and accurate as of the date hereof;

3.1.6 that the Company is not insolvent or unable to pay its debts as they fall due and will not become insolvent or unable to pay its debts as they fall due as a result of it entering into the transactions contemplated in the Plan;

3.1.7 that there has not been, nor does there continue to be a reason for the Company to be struck off the register of companies at the Registry;

3.1.8 that all consents, exemptions, licences, registrations, approvals or authorisations of any person required in relation to the transactions contemplated or entered into under or pursuant to the Plan, the execution and delivery of the documents referred to therein and the performance and observance of the terms thereof by the parties thereto (other than such consents, exemptions, licences, registrations, approvals or authorisations required of the Company under the laws and regulations of Guernsey) have been obtained and are in full force and effect at the date of this opinion; and

3.1.9 that there are no documents or information which we have not been provided with which could affect the accuracy of this opinion.

3.2 We have not independently verified the above assumptions.

4. OPINION

On the basis of and subject to the foregoing and the observations and qualifications that follow and to matters not disclosed to us, we are of the opinion that the Shares are duly authorised and are or, when issued (as applicable), will be validly issued, fully paid and non-assessable.

5. QUALIFICATIONS

The observations and qualifications referred to above are as follows:

5.1 the term “non-assessable” has no equivalent legal term under Guernsey law and for the purpose of this opinion, “non-assessable” means that a holder of a Share will not by reason of merely being such a holder, be subject to assessment or calls by the Company or its creditors for further payment on such Share;

Page 3 / 15 March 2024

5.2 information available in public registries in Guernsey is limited and in particular there is no publicly available record of charges or other security interests over the shares or assets of Guernsey companies (other than in respect of real property situated in Guernsey and Guernsey registered ships);

5.3 we offer no opinion as to whether the issue and/or transfer of the Shares pursuant to the terms set out in the Plan or the performance by the Company of its obligations in respect thereof will result in any breach of or otherwise infringe any other agreement, deed or document (other than the Articles) entered into by or binding on the Company;

5.4 we express no opinion as to any other law other than the laws of the Island of Guernsey in force at and as interpreted at the date of this opinion;

5.5 we do not give any opinion on the commerciality of any transaction contemplated or entered into by the Company in respect of the issue and/or transfer of the Shares. If in resolving to enter into the transactions the directors of the Company were not acting with a view to the best interests of the Company, they would be acting in breach of their duties as directors under the laws of Guernsey;

5.6 the search of the Public Records referred to in paragraph 2.4 above is not conclusively capable of revealing whether or not:

5.6.1 a winding up order has been made or a resolution passed for the winding up of the Company; or

5.6.2 an order has been made or a resolution passed appointing a liquidator in respect of the Company,

as notice of these matters might not be filed with the Registrar of Companies immediately and, when filed, might not be entered on the public record of the Company immediately;

5.7 there is no formal procedure for determining whether any proceedings have been commenced against the Company including as to whether proceedings have commenced to declare the property of the Company “en désastre”.

6. GENERAL

6.1 We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. We also consent to the reference to our firm under the heading “Legal Matters” in the Registration Statement. In giving this 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.

Yours faithfully
