Market Abuse Regulation

Market soundings, as defined in the UK version ("UK MAR") of the Market Abuse Regulation No. 596/2014 ("EU MAR"), which is part of English law by virtue of the European Union (Withdrawal) Act 2018 (as amended) were taken in respect of the Placing, with the result that certain persons became aware of inside information, as permitted by UK MAR. That inside information is set out in this announcement and has been disclosed as soon as possible in accordance with paragraph 7 of article 17 of UK MAR. Therefore, those persons that received inside information in a market sounding are no longer in possession of inside information relating to the Company and its securities.

Information to Distributors

Solely for the purposes of the product governance requirements contained within the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK Product Governance Rules"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK Product Governance Rules) may otherwise have with respect thereto, the Placing Shares have been subject to a product approval process, which has determined that the Placing Shares are: (i) compatible with an end target market of investors who meet the criteria of professional clients and eligible counterparties, each defined in the FCA Handbook Conduct of Business Sourcebook ("COBS"); and (ii) eligible for distribution through all distribution channels as are permitted by the UK Product Governance Rules (the "UK Target Market Assessment").

Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the "MiFID II Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" and/or "distributor" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the Placing Shares have been subject to a product approval process, which has determined that the Placing Shares are: (i) compatible with an end target market of: (a) investors who meet the criteria of professional clients and (b) eligible counterparties (each as defined in MiFID II); and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "EU Target Market Assessment").

Notwithstanding the UK Target Market Assessment and the EU Target Market Assessment, distributors should note that: the price of the Ordinary Shares may decline and investors could lose all or part of their investment; such securities offer no guaranteed income and no capital protection; and an investment in such securities is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom.

Each of the UK Target Market Assessment and the EU Target Market Assessment is without prejudice to any contractual, legal or regulatory selling restrictions in relation to the Placing. Furthermore, it is noted that, notwithstanding the UK Target Market Assessment and the EU Target Market Assessment, WHI will only procure investors who meet the criteria of professional clients and eligible counterparties each as defined under COBS or MiFID II, as applicable.

For the avoidance of doubt, each of the UK Target Market Assessment and the EU Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of Chapters 9A or 10A respectively of COBS or MiFID II, as applicable; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Placing Shares.

Each distributor is responsible for undertaking its own target market assessment in respect of the Placing Shares and determining appropriate distribution channels.

Persons (including, without limitation, nominees and trustees) who have a contractual or other legal obligation to forward a copy of this Appendix or the Announcement of which it forms part should seek appropriate advice before taking any action.

These terms and conditions apply to persons making an offer to acquire Placing Shares and should be read in their entirety. Each Placee hereby agrees with WHI and the Company to be bound by these terms and conditions. A Placee shall, without limitation, become so bound if WHI confirms to such Placee its allocation of First Placing Shares and/or Second Placing Shares.

Upon being notified of its allocation of Placing Shares, a Placee shall be contractually committed to acquire the number of Placing Shares allocated to it at the Placing Price and otherwise on the terms and conditions set out in this Announcement and, to the fullest extent permitted by law, will be deemed to have agreed not to exercise any rights to rescind or terminate or otherwise withdraw from such commitment.

In this Appendix, unless the context otherwise requires, "Placee" means a Relevant Person (including individuals, funds or others) on whose behalf a commitment to subscribe for or acquire Placing Shares has been given.

Details of the Placing Agreement and the Placing Shares

WHI and the Company have entered into a Placing Agreement, under which WHI has, on the terms and subject to the conditions set out therein, undertaken to use its reasonable endeavours to procure subscribers for the Placing Shares at the Placing Price. The Placing is not being underwritten by WHI or any other person.

The number of the Placing Shares will be determined following completion of the Placing. The timing of the closing of the Placing and the number and allocation of Placing Shares to Placees and as between the tranches of the Placing, are at the discretion of WHI, following consultation with the Company. Allocations will be confirmed orally or by email by WHI following the close of the Placing. A further announcement confirming these details will then be made as soon as practicable following completion of the Placing.

The Placing Shares will, when issued, be subject to the Articles, will be credited as fully paid and rank pari passu in all respects with the existing Ordinary Shares, including the right to receive all dividends and other distributions (if any) declared, made or paid on or in respect of Ordinary Shares after the date of issue of the First Placing Shares or (as the case may be) the Second Placing Shares.

Application for admission to trading on AIM

Application will be made to the London Stock Exchange for admission to trading on AIM of the First Placing Shares. It is expected that settlement of the First Placing Shares and First Admission will become effective at 8.00 a.m. on 30 January 2024 and that dealings in the First Placing Shares will commence at that time.

Application will be made to the London Stock Exchange for admission to trading on AIM of the Second Placing Shares. Subject (amongst other things) to the passing of the Resolutions, it is expected that settlement of the Second Placing Shares and Second Admission will become effective at 8.00 a.m. on or around 6 February 2024 and that dealings in the Second Placing Shares will commence at that time.

Placing

WHI will today commence an accelerated bookbuilding process to determine demand for participation in the Placing by potential Placees at the Placing Price. This Appendix gives details of the terms and conditions of, and the mechanics of participation in, the Placing. No commissions will be paid to Placees or by Placees in respect of any Placing Shares.

WHI and the Company shall be entitled to effect the Placing by such alternative method to the Placing as they may, in their discretion, determine.

4. To bid in the Placing, prospective Placees should communicate their bid by telephone to their usual contact at WHI. Each bid should state the number of Placing Shares which the prospective Placee wishes to subscribe. Bids may be scaled down by WHI on the basis referred to in paragraph 8 below.

Each Placee's allocation will be confirmed to Placees orally, or by email, by WHI following the close of the Placing and a trade confirmation or contract note will be dispatched as soon as possible thereafter. Oral or emailed confirmation from WHI will give rise to an irrevocable, legally binding commitment by that person (who at that point becomes a Placee), in favour of WHI and the Company, under which it agrees to acquire by subscription the number of First Placing Shares and/or Second Placing Shares allocated to it at the Placing Price and otherwise on the terms and subject to the conditions set out in this Appendix and in accordance with the Articles. Except with WHI's consent, such commitment will not be capable of variation or revocation.

7. The Company will make a further announcement following the close of the Placing detailing the results of the Placing and the number of Placing Shares to be issued at the Placing Price.

In particular, neither WHI, nor the Company, nor any of their respective affiliates, agents, directors, officers or employees shall have any liability (including to the extent permissible by law, any fiduciary duties) in respect of WHI's conduct of the Placing or of such alternative method of effecting the Placing as WHI and the Company may determine.

Right to terminate the Placing Agreement

WHI is entitled, at any time before Second Admission, to terminate the Placing Agreement by giving notice to the Company in certain circumstances, including, inter alia:

1. if any of the warranties given in the Placing Agreement are not true and accurate or are misleading in any material respect when given;

2. the Company has failed to comply with its material obligations under the Placing Agreement in the period prior to First Admission or Second Admission (as the case may be);

No Admission Document or Prospectus

The Placing Shares are being offered to a limited number of specifically invited persons only and have not been nor will they be offered in such a way as to require the publication of a prospectus in the United Kingdom or in any other jurisdiction. No offering document, admission document or prospectus has been or will be submitted to be approved by the FCA or the London Stock Exchange in relation to the Placing or the Placing Shares, and

Placees' commitments will be made solely on the basis of the information contained in the Announcement (including this Appendix) and the Publicly Available Information. Each Placee, by accepting a participation in the Placing, agrees that the content of this Announcement is exclusively the responsibility of the Company and confirms that it has not relied on any other information (other than the Publicly Available Information), representation, warranty, or statement made by or on behalf of the Company or WHI or any other person and neither WHI, the Company nor any other person will be liable for any Placee's decision to participate in the Placing based on any other information, representation, warranty or statement which the Placees may have obtained or received and, if given or made, such information, representation, warranty or statement must not be relied upon as having been authorised by WHI, the Company or their respective officers, directors, employees or agents. Each Placee acknowledges and agrees that it has relied on its own investigation of the business, financial or other position of the Company in accepting a participation in the Placing. Neither the Company nor WHI are making any undertaking or warranty to any Placee regarding the legality of an investment in the Placing Shares by such Placee under any legal, investment or similar laws or regulations. Each Placee should not consider any information in this Announcement to be legal, tax or business advice. Each Placee should consult its own solicitor, tax adviser and financial adviser for independent legal, tax and financial advice regarding an investment in the Placing Shares. Nothing in this paragraph shall exclude the liability of any person for fraudulent misrepresentation.

Registration and Settlement

Following closure of the Placing, each Placee allocated Placing Shares in the Placing will be sent a trade confirmation or contract note in accordance with the standing arrangements in place with WHI, stating the number of First Placing Shares and/or Second Placing Shares allocated to it at the Placing Price, the aggregate amount owed by such Placee (in pounds sterling) and a form of confirmation in relation to settlement instructions.

Each Placee will be deemed to agree that it will do all things necessary to ensure that delivery and payment is completed as directed by WHI in accordance with the standing CREST settlement instructions which they have in place with WHI.

Settlement of transactions in the Placing Shares (ISIN: GB00BFD3VF20) following Admission will take place within CREST provided that, subject to certain exceptions, WHI reserves the right to require settlement for, and delivery of, the Placing Shares (or a portion thereof) to Placees by such other means that it deems necessary if delivery or settlement is not possible or practicable within CREST within the timetable set out in this Announcement or would not be consistent with the regulatory requirements in any Placee's jurisdiction.

It is expected that settlement will take place in accordance with the instructions set out in the contract note.

Interest is chargeable daily on payments not received from Placees on the due date(s) in accordance with the arrangements set out above at the rate of 4 percentage points above the prevailing Bank of England base rate as determined by WHI.

Each Placee is deemed to agree that, if it does not comply with these obligations, WHI may sell any or all of the Placing Shares allocated to that Placee on such Placee's behalf and retain from the proceeds, for WHI's account and benefit (as agent for the Company), an amount equal to the aggregate amount owed by the Placee plus any interest due. The relevant Placee will, however, remain liable and shall indemnify WHI on demand for any shortfall below the aggregate amount owed by it and may be required to bear any stamp duty or stamp duty reserve tax or securities transfer tax (together with any interest or penalties) which may arise upon the sale of such Placing Shares on such Placee's behalf. By communicating a bid for Placing Shares, each Placee confers on WHI such authorities and powers necessary to carry out any such sale and agrees to ratify and confirm all actions which WHI lawfully takes in pursuance of such sale. Legal and/or beneficial title in and to any Placing Shares shall not pass to the relevant Placee until it has fully complied with its obligations hereunder.

If Placing Shares are to be delivered to a custodian or settlement agent, Placees should ensure that the form of confirmation is copied and delivered immediately to the relevant person within that organisation.

Insofar as Placing Shares are registered in a Placee's name or that of its nominee or in the name of any person for whom a Placee is contracting as agent or that of a nominee for such person, such Placing Shares should, subject as provided below, be so registered free from any liability to UK stamp duty or stamp duty reserve tax or securities transfer tax. Neither WHI nor the Company will be liable in any circumstances for the payment of stamp duty, stamp duty reserve tax or securities transfer tax in connection with any of the Placing Shares. Placees will not be entitled to receive any fee or commission in connection with the Placing.

The provisions of this Appendix may be waived, varied or modified as regards specific Placees or on a general basis by WHI.

The agreement to settle a Placee's subscription and/or purchase (and/or the subscription of a person for whom such Placee is contracting as agent) free of stamp duty and stamp duty reserve tax depends on the settlement relating only to a subscription by it and/or such person direct from the Company for the Placing Shares in question. Such agreement assumes that the Placing Shares are not being subscribed for in connection with arrangements to issue depositary receipts or to transfer the Placing Shares into a clearance service. If there are any such arrangements, or the settlement relates to any other subsequent dealing in the Placing Shares, stamp duty or stamp duty reserve tax may be payable, for which neither the Company or WHI will be responsible, and the Placee to whom (or on behalf of whom, or in respect of the person for whom it is participating in the Placing as an agent or nominee) the allocation, allotment, issue or delivery of Placing Shares has given rise to such UK stamp duty or stamp duty reserve tax undertakes to pay such UK stamp duty or stamp duty reserve tax forthwith and to indemnify on an after-tax basis and to hold harmless the Company and WHI in the event that any of the Company and/or WHI have incurred any such liability to UK stamp duty or stamp duty reserve tax. If this is the case, each Placee should seek its own advice and notify WHI accordingly.

In addition, Placees should note that they will be liable for any stamp duty and all other stamp, issue, securities, transfer, registration, documentary or other duties or taxes (including any interest, fines or penalties relating thereto) payable outside the UK by them or any other person on the subscription or purchase by them of any Placing Shares or the agreement by them to subscribe for or purchase any Placing Shares.

All times and dates in this Announcement (including the Appendices) may be subject to amendment. WHI shall notify the Placees and any person acting on behalf of the Placees of any changes.

This Announcement has been issued by, and is the sole responsibility, of the Company. No representation or warranty express or implied, is or will be made as to, or in relation to, and no responsibility or liability is or will be accepted by WHI or by any of its respective affiliates or agents as to or in relation to, the accuracy or completeness of this Announcement or any other written or oral information made available to or publicly available to any interested party or its advisers, and any liability therefore is expressly disclaimed.
