This opinion is furnished to you in connection with the Registration Statement on Form F-3 (the “Registration Statement”) filed with the United States Securities and Exchange Commission (the “Commission”) on 28 July 2026. We have acted as your English legal advisers in connection with the registration of the Securities under the United States Securities Act of 1933 (the “Securities Act”).

This opinion is limited to English law as applied by the English courts and, in effect on the date of this opinion. Such laws and practice are subject to change, possibly with retrospective effect.

In particular, we have not been asked to, and we do not express (i) any opinion as to any duties or taxes that will or may arise as a result of any other transaction effected in connection with the Securities or (ii) any opinion as to any other taxation matter which will or may arise as a result of any transaction effected in connection with the Securities.

For the purpose of this opinion we have examined the documents listed and, where appropriate, defined in the Schedule to this opinion. This opinion is given on the basis that, since the date of this opinion, or as the case may be, the date of certification of the documents listed in the Schedule to this opinion, there has been no amendment to, or termination or replacement of, such documents.

We have assumed that:

6.1

all copy documents conform to the originals and all originals are genuine and complete;

6.2

each signature is the genuine signature of the individual concerned;

6.3

(except in the case of the Issuer) all relevant documents are within the capacity and powers of, and have been validly authorised by, each party;

6.4

(in the case of each party) those documents have been or (in the case of the Securities) will be validly executed and delivered by the relevant party;

6.5

each issue of Securities will be duly authorised by the Issuer and in respect of each issue of Ordinary Shares, Equity Warrants or Preference Shares, the Issuer will have sufficient authorised but unissued share capital and the directors of the Issuer will have been granted the necessary authority to allot the relevant Securities;

6.6

the meeting of the Board of Directors of the Issuer held on 27 July 2026 (in respect of which a certified extract of the Minutes has been supplied to us) was duly convened, constituted and quorate and the resolutions referred to in the Minutes were validly passed and remain in full force and effect without modification;

6.7

the Minutes and other corporate documents are a true and complete record of the proceedings and/or resolutions described therein;

6.8

each of the documents which are the subject of this opinion is valid and binding on each party under the law to which it is expressed to be subject where that is not English law and that words and phrases used in those documents have the same meaning and effect as they would if those documents were governed by English law; and

6.9

the terms of any series of Debt Securities will not be inconsistent with the provisions of the Indenture and there will be no provision in any supplement to the prospectus dated 28 July 2026 (the “Prospectus”) or the Registration Statement or any other document which would affect the content of this opinion.

Based on the documents referred to, and assumptions made, in paragraphs 5 and 6 above, and subject to the qualifications in paragraphs 9 below and to any matters not disclosed to us, we are of the following opinion:

7.1

The Issuer has been incorporated and is existing as a company with limited liability under the laws of England.

7.2

The Issuer has corporate power to enter into and to perform its obligations under the Indenture and the Securities Depositary Agreement and has taken all necessary corporate action to authorise its execution, delivery and performance of the Indenture and the Securities Depositary Agreement.

7.3

The subordination provisions of the Securities which are expressed to be governed by English law, constitute legal, valid, binding and enforceable terms.

Page 2 of 5

7.4

When the Ordinary Shares and the Preference Shares are issued and delivered against payment therefor as contemplated in the Registration Statement and in conformity with the Articles of Association of the Issuer and so as not to violate any applicable law, such Ordinary Shares and Preference Shares will be validly issued and fully paid up and no further contributions in respect of such Ordinary Shares and Preference Shares when issued as contemplated in the Registration Statement will be required to be made to the Issuer by the holders thereof, by reason solely of their being such holders.

The term “enforceable” as used above means that the obligations assumed by the relevant party under the relevant document are of a type which the English courts enforce. It does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular:

8.1

Enforcement may be limited by (a) bankruptcy, insolvency, liquidation and moratorium laws, (b) laws relating to reorganisation and (c) laws of general application relating to or affecting the rights of creditors.

8.2

Enforcement may be limited by general principles of equity – for example, equitable remedies may not be available where damages are considered to be an adequate remedy.

8.3

Claims may become barred under the Limitation Act 1980 or may be or become subject to set-off or counterclaim.

This opinion is subject to the following:

9.1

It should be understood that we have not been responsible for investigating or verifying the accuracy of the facts, including statements of foreign law, or the reasonableness of any statements of opinion, contained in the Prospectus as amended, superseded or supplemented by the Prospectus Supplement, or that no material facts have been omitted from them.

9.2

We express no opinion as to compliance or otherwise with (i) any financial limitations on borrowings or covenants by the Issuer contained in the Articles of Association of the Issuer or (ii) any limitations on the maximum aggregate principal amount of Securities which may be issued by the Issuer as contemplated by the Registration Statement.

9.3

To the extent it relates to United Kingdom stamp duties any undertaking or indemnity may be void under Section 117 of the Stamp Act 1891.

9.4

A certificate, determination, notification, minute or opinion might be held by the English courts not to be conclusive if it could be shown to have an unreasonable or arbitrary basis or in the event of manifest error despite any provision in any document to the contrary.

9.5

An English court may refuse to give effect to any contractual provision concerning payment of the costs of enforcement or litigation brought before an English court.

9.6

Any contractual provision that purports to maintain the validity of the remainder of such contract despite the invalidity, illegality or unenforceability of one or more of its provisions may not be effective - it depends on the nature of the illegality, invalidity or unenforceability in question.

Page 3 of 5

9.7

Any contractual provision that requires a variation to be made in writing or to comply with any other formality may not be enforceable.

9.8

Any amount referred to in provisions of the Securities or any Principal Agreement which provide for the payment by a person of additional interest or amounts upon a breach, default or similar occurrence by that person may not be recoverable if it amounts to a penalty under English law.

9.9

An English court may, or may be required to, stay proceedings or decline jurisdiction in certain circumstances - for example, if proceedings are brought elsewhere.

9.10

We express no opinion as to the effect of any sanctions or other similar restrictive measures in relation to any party to the Principal Agreements or the Securities or any transaction contemplated thereby.

9.11

Our opinion that the Issuer is existing is based on the Search and the Winding-up Search. It should be noted that the Search and the Winding-up Search are not capable of revealing conclusively whether or not a winding-up or administration petition or order has been presented or made, a receiver has been appointed, a company voluntary arrangement has been proposed or approved, a moratorium has been applied for or has come into force or any other insolvency proceeding has commenced.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to us made under the heading “Validity of Securities” in the Registration Statement. In giving this consent we do not admit that we are within the category of persons whose consent is required within Section 7 of the Securities Act or the rules and regulations of the Commission thereunder.

Yours faithfully
