Product Governance Disclaimer

UK Product Governance Requirements

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 New Ordinary Shares have been subject to a product approval process, which has determined that such New Ordinary Shares are: (a) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in Chapter 3 of the FCA Handbook Conduct of Business Sourcebook ("COBS"); and (b) eligible for distribution through all permitted distribution channels (the "UK target market assessment"). Notwithstanding the UK target market assessment, distributors should note that: the price of the New Ordinary Shares may decline and investors could lose all or part of their investment; the New Ordinary Shares offer no guaranteed income and no capital protection; and an investment in the New Ordinary Shares 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. The UK target market assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Placing. Furthermore, it is noted that, notwithstanding the UK target market assessment, the Joint Bookrunners will only procure investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the UK target market assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of COBS 9A and COBS 10A, respectively; 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 New Ordinary Shares. Each distributor is responsible for undertaking its own UK target market assessment in respect of the New Ordinary Shares and determining appropriate distribution channels.

EU Product Governance Requirements

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" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the New Ordinary Shares have been subject to a product approval process, which has determined that the New Ordinary Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "Target Market Assessment").

Notwithstanding the Target Market Assessment, distributors should note that: the price of the New Ordinary Shares may decline and investors could lose all or part of their investment; the New Ordinary Shares offer no guaranteed income and no capital protection; and an investment in the New Ordinary Shares 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. The Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the New Ordinary Shares. Furthermore, it is noted that, notwithstanding the Target Market Assessment, the Joint Bookrunners have only procured investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; 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 New Ordinary Shares.

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

Bookbuild

The Joint Bookrunners will today commence an accelerated bookbuilding process to determine demand for participation in the Placing by potential Placees. The Joint Bookrunners and the Company shall be entitled to effect the Placing by such alternative method to the Bookbuild as they may, in their sole discretion determine.

Details of the Placing

The Joint Bookrunners have entered into the Placing Agreement with the Company under which the Joint Bookrunners have severally (and not jointly or jointly and severally) agreed, on the terms and subject to the conditions set out therein, undertaken to use their reasonable endeavours to procure, as the Company's placing agent and joint bookrunner for the purpose of the Placing, subscribers for the Placing Shares at the Issue Price.

The final number of Placing Shares will be decided at the close of the Bookbuild following the execution of the terms of the Placing by the Company and the Joint Bookrunners (the "Term Sheet").

The Placing Agreement contains customary undertakings and warranties given by the Company to the Joint Bookrunners including as to the accuracy of information contained in this Announcement and to be contained in the Circular, to matters relating to the Company and its business and a customary indemnity given by the Company to the Joint Bookrunners in respect of liabilities arising out of or in connection with the Placing and/or Admissions.

The Company is also separately making an Open Offer of such number of New Ordinary Shares as will be set out in the Circular.

The Capital Raise is conditional upon, inter alia:

a) the Circular being sent to Qualifying Shareholders and (for information only) to Excluded Overseas Shareholders who have notified an address in the United Kingdom for the service of documents in accordance with the Articles. A copy of the Circular will be available from the Company's website at www.scancell.co.uk;

b) First Admission becoming effective; and

c) the obligations of the Joint Bookrunners under the Placing Agreement not having been terminated in accordance with its terms.

The number of Placing Shares will be determined following completion of the Bookbuild as set out in this Announcement.

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

Lock up

As part of the Placing, the Company has agreed that it will not issue or sell any Ordinary Shares for a period of 120 days after the Second Admission (or First Admission in the event Second Admission does not occur) without the prior written consent of the Joint Bookrunners (such consent not to be unreasonably withheld or delayed). That agreement is subject to (i) the customary exception of granting options under, and allotting and issuing Ordinary Shares in the ordinary course pursuant to, the Company's existing share schemes and (ii) an exception relating to any allotment or issue of Ordinary Shares pursuant to the conversion of the Convertible Loan Notes.

Application for admission to trading

Application will be made to the London Stock Exchange for First Admission. It is expected that settlement of the Placing Shares will take place and First Admission will become effective on or around 5 December 2023 and that dealings in the Placing Shares will commence at that time.

Participation in, and principal terms of, the Placing

1. Each Joint Bookrunner is arranging the Placing as placing agent and joint bookrunner of the Company for the purpose of using its reasonable endeavours to procure Placees at the Issue Price for the Placing Shares.

2. Participation in the Placing will only be available to persons who may lawfully be, and are, invited to participate by the Joint Bookrunners. The Joint Bookrunners and their respective affiliates may participate in the Placing as principal.

3. 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.

4. The Bookbuild, if successful, will establish the number of Placing Shares to be issued at the Issue Price. The number of Placing Shares to be issued will be agreed between Stifel, WG Partners and the Company following completion of the Bookbuild. The number of Placing Shares will be announced on a Regulatory Information Service following the completion of the Bookbuild.

5. To bid in the Bookbuild, prospective Placees should communicate their bid by telephone or email to their usual sales contact at one of the Joint Bookrunners. Each bid should state the number of Placing Shares which the prospective Placee wishes to subscribe for at the Issue Price which is ultimately established by the Company and the Joint Bookrunners. Bids may be scaled down by the Joint Bookrunners on the basis referred to in paragraph 9 below.

6. The timing of the closing of the Bookbuild will be at the discretion of the Joint Bookrunners. The Company reserves the right (upon agreement with the Joint Bookrunners) to reduce or seek to increase the amount to be raised pursuant to the Placing, in its absolute discretion.

7. Each Placee's allocation will be confirmed to Placees orally or by email by the relevant Joint Bookrunner, and evidenced by a trade confirmation or contract note which will be dispatched as soon as practicable thereafter. The terms of this Appendix will be deemed incorporated by reference therein. The oral or email confirmation to such Placee will constitute an irrevocable legally binding commitment upon such person (who will at that point become a Placee) in favour of the Joint Bookrunners and the Company, under which it agrees to acquire the number of Placing Shares allocated to it at the Issue Price on the terms and conditions set out in this Appendix and in accordance with the Company's articles of association. Except as required by law or regulation, no press release or other announcement will be made by Stifel, WG Partners or the Company using the name of any Placee (or its agent), in its capacity as Placee (or agent), other than with such Placee's prior written consent.

8. The Company will make a further announcement following the close of the Bookbuild detailing the number of Placing Shares to be issued at the Issue Price.

9. Subject to paragraphs 5 and 6 above, the Joint Bookrunners may choose to accept bids, either in whole or in part, on the basis of allocations determined at their discretion (in agreement with the Company) and may scale down any bids for this purpose on such basis as they may determine. The Joint Bookrunners may also, notwithstanding paragraphs 5 and 6 above, subject to the prior consent of the Company: (a) allocate Placing Shares after the time of any initial allocation to any person submitting a bid after that time; and (b) allocate Placing Shares after the Bookbuild has closed to any person submitting a bid after that time.

10. The allocation of Placing Shares to Placees located in the United States (each, a "US Placee") shall be conditional on the execution by each US Placee of a US Investor Representation Letter in the form provided to it by one of the Joint Bookrunners or their respective affiliates.

11. Each Placee will have an immediate, separate, irrevocable and binding obligation, owed to the Joint Bookrunners, to pay in cleared funds immediately on the settlement date (or as separately agreed with the Joint Bookrunners in the case of certificated settlement), in accordance with the registration and settlement requirements set out below, an amount equal to the product of the Issue Price and the number of Placing Shares such Placee has agreed to take up and the Company has agreed to allot.

12. Irrespective of the time at which a Placee's allocation pursuant to the Placing is confirmed, settlement for all Placing Shares to be acquired pursuant to the Placing will be required to be made at the times and on the basis explained below under "Registration and Settlement".

13. All obligations under the Placing will be subject to fulfilment or (where applicable) waiver of, inter alia, the conditions referred to below under "Conditions of the Placing" and to the Placing not being terminated on the basis referred to below under "Right to terminate under the Placing Agreement".

14. By participating in the Placing, each Placee will agree that its rights and obligations in respect of the Placing will terminate only in the circumstances described below and will not be capable of rescission or termination by the Placee.

15. To the fullest extent permissible by law, none of the Company, the Joint Bookrunners or any of their respective affiliates shall have any responsibility or liability (whether in contract, tort or otherwise) to any Placee (or to any other person whether acting on behalf of a Placee or otherwise) under these terms and conditions. In particular, none of the Company, the Joint Bookrunners or any of their respective affiliates shall have any liability (whether in contract, tort or otherwise and including, to the fullest extent permissible by law, any fiduciary duties) in respect of the Joint Bookrunners' conduct of the Bookbuild or Placing. Each Placee acknowledges and agrees that the Company is responsible for the allotment of the Placing Shares to the Placees and the Joint Bookrunners shall have no liability to the Placees for the failure of the Company to fulfil those obligations.

Conditions of the Placing

The Joint Bookrunners' obligations under the Placing Agreement in respect of the Placing Shares are conditional on, inter alia:

a) the Company allotting, subject only to First Admission, the Placing Shares in accordance with the Placing Agreement; and

b) First Admission taking place not later than 8:00 a.m. (London time) on 5 December 2023 or such later time and/or date as may be agreed between the Company and the Joint Bookrunners, not being later than 8:00 a.m. on the Placing Final Date.

If (i) any of the conditions contained in the Placing Agreement in respect of the Placing Shares are not fulfilled or waived by the Joint Bookrunners by the time or date where specified (or such later time or date as the Company and the Joint Bookrunners may agree, not being later than the Placing Final Date), or (ii) the Placing Agreement is terminated as described below, the Placing will lapse and the Placees' rights and obligations hereunder in relation to the Placing Shares shall cease and terminate at such time and each Placee agrees that no claim can be made by the Placee in respect thereof. For the avoidance of doubt the Placing shall not be conditional on the Open Offer being subscribed for by Qualifying Shareholders.

Each Joint Bookrunner may, in its absolute discretion, waive, or extend the period (up to the Placing Final Date) for, compliance by the Company with the whole or any part of any of the Company's obligations in relation to the conditions in the Placing Agreement, save that certain conditions, including but not limited to First Admission taking place and the Company allotting the Placing Shares subject only to First Admission may not be waived and the period for compliance with such conditions may not be extended. Any such extension or waiver will not affect Placees' commitments as set out in this Announcement.

None of the Joint Bookrunners or the Company, nor any of their respective affiliates, agents, directors, officers, consultants or employees, shall have any liability to any Placee (or to any other person whether acting on behalf of a Placee or otherwise) in respect of any decision they may make as to whether or not to waive or to extend the time and/or date for the satisfaction of any condition to the Placing nor for any decision they may make as to the satisfaction of any condition or in respect of the Placing generally and by participating in the Placing each Placee agrees that any such decision is within the absolute discretion of Stifel and WG Partners.

Right to terminate under the Placing Agreement

Stifel and WG Partners are severally entitled in their absolute discretion, at any time before First Admission, to terminate the Placing Agreement by giving notice to the Company in the following circumstances:

(a) in the opinion of that Relevant Bookrunner (acting in good faith), the warranties given by the Company to the Joint Bookrunners are not true and accurate or have become misleading (or would not be true and accurate or would be misleading if they were repeated at any time before First Admission) by reference to the facts subsisting at the time when the notice referred to above is given; or

(b) in the opinion of that Relevant Bookrunner (acting in good faith), the Company fails to comply with any of its obligations under the Placing Agreement and that failure is material in the context of the Placing, the Subscription, the Open Offer and/or the Admissions;

(c) a matter having arisen in respect of which indemnification may be sought from the Company under the indemnity included in the Placing Agreement;

(d) the application for First Admission having been withdrawn or rejected;

(e) in the opinion of that Relevant Bookrunner (acting in good faith), there has been a development or event (or any development or event involving a prospective change of which the Company is or might reasonably be expected to be, aware) which will or is likely to have a material adverse effect on or affecting the operations, the condition (financial, operational, legal or otherwise), prospects, management, results of operations, financial position, business or general affairs of the Company or the Group respectively whether or not foreseeable and whether or not arising in the ordinary course of business; or

(f) there has been a change in national or international financial, political, economic or stock market conditions (primary or secondary); an incident of terrorism, outbreak or escalation of hostilities, war, declaration of martial law; a material deterioration in, or material escalation in the response to the COVID-19 pandemic; a suspension or material limitation in trading of securities generally on any stock exchange; any change in currency exchange rates or exchange controls or a disruption of settlement systems or a material disruption in commercial banking, in each case as would be likely in the opinion of that Relevant Bookrunner (acting in good faith) to materially prejudice the success of the Placing, the Subscription, the Open Offer and/or the Admissions.

The rights and obligations of the Placees shall terminate only in the circumstances described in these terms and conditions and in the Placing Agreement and will not be subject to termination by the Placee or any prospective Placee at any time or in any circumstances. By participating in the Placing, Placees agree that the exercise by either Joint Bookrunner of any right of termination or other discretion under the Placing Agreement shall be within the absolute discretion of that Joint Bookrunner, and that it need not make any reference to Placees and that it shall have no liability to Placees whatsoever in connection with any such exercise or decision not to exercise. Placees will have no rights against Stifel, WG Partners, the Company or any of their respective directors or employees under the Placing Agreement pursuant to the Contracts (Rights of Third Parties) Act 1999 (as amended).

No admission document or prospectus

The Placing Shares are being offered to a limited number of specifically invited persons only and will not be offered in such a way as to require an admission document or 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 submitted to the London Stock Exchange in relation to the Placing, and Placees' commitments will be made solely on the basis of the information contained in the Announcement (including the Appendices) and the Exchange 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 neither received nor relied on any other information (other than the Exchange Information), representation, warranty, or statement made by or on behalf of the Company, the Joint Bookrunners, or any other person and neither the Joint Bookrunners, 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 the Joint Bookrunners, the Company, or their respective officers, directors, consultants, 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 the Joint Bookrunners is 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

Settlement of transactions in the Placing Shares (ISIN: GB00B63D3314) following First Admission will take place within CREST, provided that, subject to certain exceptions, the Joint Bookrunners reserve 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.

Following the close of the Bookbuild, each Placee allocated Placing Shares in the Placing will be sent a trade confirmation or contract note stating the number of Placing Shares allocated to it at the Issue Price, the aggregate amount owed by such Placee to Stifel (as agent for the Company) and settlement instructions. Each Placee agrees that it will do all things necessary to ensure that delivery and payment is completed in accordance with either the CREST or certificated settlement instructions that it has in place with Stifel. Settlement will be through Stifel against CREST participant account: 2304200 (CREST ID: 2OQAN). For the avoidance of doubt, Placing allocations are expected to be booked with a trade date of 30 November 2023 and settlement date of 5 December 2023 on a T+2 basis in accordance with the instructions set out in the trade confirmation.

The Company will instruct its registrar to deliver the Placing Shares to the CREST account operated by Stifel as agent for the Company and the Relevant Bookrunner will enter its delivery (DEL) instruction into the CREST system. The input to CREST by a Placee of a matching or acceptance instruction will then allow delivery of the relevant Placing Shares to that Placee against payment.

If a Placee wishes to receive its Placing Shares in certificated form, it should contact Stifel (+44(0)20 7710 7675) or WG Partners (+44(0)20 3705 9321) as soon as possible after receipt of the allocation confirmation.

Placees who wish to receive their Placing Shares in certificated form are expected to receive their certificates for their Placing Shares within 14 days of allotment, provided payment in full has been made.

Interest is chargeable daily on payments not received from Placees on the due date in accordance with the arrangements set out above at the rate of two percentage points above the Sterling Overnight Index Average (SONIA) as determined by the Joint Bookrunners.

Each Placee is deemed to agree that, if it does not comply with these obligations, the Joint Bookrunners may sell any or all of the Placing Shares allocated to that Placee on such Placee's behalf and retain from the proceeds, for the Joint Bookrunners' account and benefit (as agent for the Company), an amount equal to the aggregate amount owed by the Placee plus any interest due.

35. agrees that the Company, the Joint Bookrunners and their respective affiliates and others will rely upon the truth and accuracy of the foregoing representations, warranties, acknowledgements and undertakings which are given to the Joint Bookrunners on their own behalf and on behalf of the Company and are irrevocable and are irrevocably authorised to produce this Announcement or a copy thereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby;

39. acknowledges that its commitment to subscribe for Placing Shares on the terms set out herein and in the trade confirmation or contract note will continue notwithstanding any amendment that may in future be made to the terms of the Placing and that Placees will have no right to be consulted or require that their consent be obtained with respect to the Company's conduct of the Placing;

42. to the fullest extent permitted by law, it acknowledges and agrees to the disclaimers contained in the Announcement including this Appendix.

The representations, warranties, acknowledgments and undertakings contained in this Appendix are given to the Joint Bookrunners and the Company and are irrevocable and shall not be capable of termination in any circumstances.

The agreement to settle a Placee's subscription (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 none of the Company or the Joint Bookrunners 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 the Joint Bookrunners in the event that any of the Company or the Joint Bookrunners has 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 the Joint Bookrunners 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 by them of any Placing Shares or the agreement by them to subscribe for any Placing Shares.

Each Placee, and any person acting on behalf of the Placee, acknowledges that neither Joint Bookrunner owes any fiduciary or other duties to any Placee in respect of any representations, warranties, undertakings or indemnities in the Placing Agreement.

When a Placee or person acting on behalf of the Placee is dealing with the Joint Bookrunners, any money held in an account with either Joint Bookrunner on behalf of the Placee and/or any person acting on behalf of the Placee will not be treated as client money within the meaning of the rules and regulations of the FCA made under the FSMA. The Placee acknowledges that the money will not be subject to the protections conferred by the client money rules; as a consequence, this money will not be segregated from the Relevant Bookrunner's money in accordance with the client money rules and will be used by the Relevant Bookrunner in the course of its own business and the Placee will rank only as a general creditor of the Relevant Bookrunner.

All times and dates in this Announcement may be subject to amendment. The Joint Bookrunners shall notify the Placees and any person acting on behalf of the Placees of any changes.

Past performance is no guide to future performance and persons needing advice should consult an independent financial adviser.
