Solvonis Therapeutics plc

("Solvonis" or the "Company")

Proposed equity fundraising to raise a minimum of approximately £2 million

Further to the Company's announcement on 24 February 2025, Solvonis Therapeutics plc (LSE: SVNS), an innovative biotechnology company co-developing therapeutics for mental health disorders, announces its intention to carry out an equity fundraising to raise a minimum of approximately £2 million through an issue of new Ordinary Shares (the "Fundraise Shares") to new and existing institutional and other investors (the "Fundraise") at a fixed issue price of 0.13 pence per Fundraise Share (the "Issue Price").

Following the Company's entry into an arrangement agreement (the "Arrangement Agreement") with Awakn Life Sciences Corp. ("Awakn") on 22 February 2025 and having now satisfied the key conditions for the proposed acquisition of Awakn (the "Proposed Acquisition"), the proceeds of the Fundraise, net of expenses relating to both the Fundraise and the Proposed Acquisition, as well as taking into account the Company's existing cash resources, will provide the Company with sufficient working capital for the requirements of the enlarged group, thereby satisfying one of the remaining conditions under the Arrangement Agreement.

The Fundraise is being conducted via an accelerated bookbuild process (the "Bookbuild") to be undertaken by Allenby Capital Limited ("Allenby") and Singer Capital Markets Securities Limited ("Singer"), the Company's joint brokers (together, the "Joint Bookrunners" or "Joint Brokers"). The Bookbuild will be launched immediately following the publication of this announcement. The final number of Fundraise Shares to be issued will be determined at the close of the Bookbuild and the result will be announced as soon as practicable thereafter. The Fundraise is subject to the terms and conditions set out in Appendix I to this announcement (the "Announcement").

The Fundraise is conditional upon, inter alia: (i) a placing agreement dated 15 May 2025 between the Company, Allenby and Singer (the "Placing Agreement") not having been terminated and becoming unconditional; (ii) the publication by the Company of a prospectus (the "Prospectus") approved by the Financial Conduct Authority (the "FCA"); and (iii) admission of the Fundraise Shares and the new Ordinary Shares to be issued pursuant to the Arrangement Agreement (the "Consideration Shares") to trading on the Main Market of the London Stock Exchange and to the Official List Equity Shares (transition) category of the FCA ("Admission").

The Fundraise is being undertaken on a reasonable endeavours basis but is not being underwritten by Allenby, Singer or any other person.

Certain directors of the Company and another person discharging managerial responsibilities on its behalf intend to participate in the Fundraise but it is not available to the public generally.

Further details of the Bookbuild and the Proposed Acquisition are provided below and in the Appendices to this Announcement.

Proposed Acquisition terms

Solvonis is issuing 2,074,378,528 Consideration Shares as consideration for the Proposed Acquisition. The Proposed Acquisition values Awakn at approximately £4.98 million (based upon a closing price of 0.24 pence per Solvonis ordinary share on 13 December 2024, being the business day before the Company announced that it had entered into a binding letter of agreement with Awakn regarding the Proposed Acquisition). Solvonis will issue to Awakn shareholders 46.67 Consideration Shares for every one common share held by or due to them (the "Exchange Ratio"). Based on the same Exchange Ratio, the holders of Awakn's common shares, restricted share units (the "RSUs") and deferred share units (the "DSUs") will receive 46.67 Consideration Shares for each one common share, DSU and RSU held by them.

It is proposed that all issued and outstanding common share purchase warrants in Awakn (the "Awakn Warrants") will be exchanged for 703,465,432 warrants over new Ordinary Shares based upon the Exchange Ratio.

Strategic and commercial significance

The Proposed Acquisition represents a major step for Solvonis and underscores the Company's strategy to address significant unmet needs in the treatment of mental health and addiction. The assets being acquired include Awakn's AWKN-001, AWKN-002 and AWKN-SDN-14 research and development programmes targeting severe alcohol use disorder ("AUD") and Post-Traumatic Stress Disorder ("PTSD") respectively.

AWKN-001 and AWKN-002 are two clinical-stage assets targeting AUD, a condition that the Company estimates affects approximately 40 million individuals across the U.S. and key European markets, and for which existing treatment options are deemed inadequate.

AWKN-001 is a Phase 3 novel investigational combination therapy for severe AUD with targeted regulatory pathways in the UK and EU that may confer up to 10 years of regulatory data and market protection. AWKN-002 is a proprietary Phase 2b planning sublingual/buccal esketamine formulation under development for moderate to severe AUD.

Further details of the Proposed Acquisition were announced by Solvonis on 24 February 2025.

The Fundraise and the Bookbuild are subject to the Terms and Conditions set out in Appendix I to this Announcement.

The Joint Brokers will commence the Bookbuild and the Bookbuild will open immediately following the release of this Announcement. The timing of the closing of the Bookbuild and allocations are at the absolute discretion of the Company and the Joint Brokers. The number of Fundraise Shares to be placed in the Bookbuild at the Issue Price will be determined following closing of the Bookbuild. Details of the result of the Bookbuild and the number of Fundraise Shares to be issued will be announced as soon as practicable after the close of the Bookbuild.

The Fundraise is conditional upon, among other things, completion of the Proposed Acquisition, Admission becoming effective, the Prospectus being published by the Company and the Placing Agreement not being terminated in accordance with its terms.

The Fundraise Shares will, when issued, be credited as fully paid and will rank pari passu in all respects with the Company's then existing ordinary shares and the Consideration Shares, including the right to receive all dividends and other distributions declared, made or paid on or in respect of all such shares after the date of issue.

Application will be made for admission of the Fundraise Shares and the Consideration Shares to trading on the Main Market of the London Stock Exchange and to listing on the Official List Equity Shares (transition) category of the FCA. It is expected that Admission will become effective on or around 27 May 2025.

Persons who choose to participate in the Fundraise, by making an oral, electronic or written offer to subscribe for Fundraise Shares, will be deemed to have read and understood this Announcement (including the Appendices) in its entirety and to be making such offer on the terms and subject to the conditions herein, and to be providing the representations, warranties, agreements, acknowledgements and undertakings contained in Appendix I.

The Placing Shares will, when issued, be credited as fully paid up and will be issued subject to the Company's articles of association and rank pari passu in all respects with the Existing Ordinary Shares, including the right to receive all dividends and other distributions declared, made or paid on or in respect of the Ordinary Shares after the date of issue of the Placing Shares, and will on issue be free of all pre-emption rights, claims, liens, charges, encumbrances and equities.

Bookbuild Process

Commencing immediately today, Allenby and Singer will be conducting the Bookbuild in order to determine demand for participation in the Placing by Placees. This Announcement gives details of the terms and conditions of, and the mechanics for participation in, the Placing. However, Allenby, Singer 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.

Participation in, and principal terms of, the Bookbuild

• Allenby and Singer are acting as joint brokers and joint bookrunners to the Placing, as agents for and on behalf of the Company, on the terms and subject to the conditions of the Placing Agreement.
• Participation in the Placing is by invitation only and will only be available to persons who may lawfully be, and are, invited to participate by Allenby or Singer. Allenby and Singer as well as any Allenby Affiliates and Singer Affiliates are also entitled to participate as Placees in the Bookbuild.
• The Bookbuild will establish the number of Placing Shares to be issued pursuant to the Placing.

• A Placee who wishes to participate in the Bookbuild should communicate its bid orally by telephone or in writing to their usual sales contact at Allenby or Singer (as the case may be).

If successful, Allenby and/or Singer will re-contact and confirm orally or in writing to Placees following the close of the Bookbuild the size of their respective allocations and a trade confirmation will be despatched as soon as possible thereafter. The oral or written confirmation of the size of allocations by Allenby or Singer (as the case may be) will constitute an irrevocable legally binding agreement in favour of the Company and Allenby and Singer pursuant to which each such Placee will be required to accept the number of Placing Shares allocated to the Placee at the Issue Price on the terms and subject to the conditions set out herein and in accordance with the Company's articles of association. Each Placee's allocation and commitment will be evidenced by a trade confirmation issued to such Placee by Allenby or Singer (as the case may be). The terms of this Appendix I will be deemed incorporated in that trade confirmation.
• Allenby and/or Singer reserves the right to scale back the number of Placing Shares to be subscribed by any Placee in the event that the Placing is oversubscribed. Allenby and Singer also reserve the right not to accept offers to subscribe for Placing Shares or to accept such offers in part rather than in whole. The acceptance and, if applicable, scaling back of offers shall be at the absolute discretion of Allenby, Singer and the Company.
• Each Placee's obligations will be owed to the Company and to Allenby and Singer. Following the oral confirmation referred to above, each Placee will also have an immediate, separate, irrevocable and binding obligation, owed to the Company, Allenby and Singer, as agents of the Company, to pay to Allenby and/or Singer (or as each of them may respectively direct), in cleared funds, an amount equal to the product of the Issue Price and the number of Placing Shares allocated to such Placee.
• To the fullest extent permissible by law, none of Allenby, any holding company of Allenby, any subsidiary of Allenby, any subsidiary of any such holding company, any branch, affiliate or associated undertaking of any such company nor any of their respective directors, agents, officers and employees (each an "Allenby Affiliate") nor any person acting on their behalf shall have any responsibility or liability to Placees (or to any other person whether acting on behalf of a Placee or otherwise). In particular, none of Allenby, any Allenby Affiliate nor any person acting on their behalf shall have any liability (including, to the extent legally permissible, any fiduciary duties) in respect of its conduct of the Bookbuild or of such alternative method of effecting the Placing as Allenby may determine.
• To the fullest extent permissible by law, none of Singer, any holding company of Singer, any subsidiary of Singer, any subsidiary of any such holding company, any branch, affiliate or associated undertaking of any such company nor any of their respective directors, agents, officers and employees (each a "Singer Affiliate") nor any person acting on their behalf shall have any responsibility or liability to Placees (or to any other person whether acting on behalf of a Placee or otherwise). In particular, none of Singer, any Singer Affiliate nor any person acting on their behalf shall have any liability (including, to the extent legally permissible, any fiduciary duties), in respect of its conduct of the Bookbuild or of such alternative method of effecting the Placing as Singer may determine.
• The Placing Shares will be issued subject to the terms and conditions of this Appendix I and each Placee's commitment to subscribe for Placing Shares on the terms set out herein will continue notwithstanding any amendment that may in future be made to the terms and conditions of the Placing and Placees will have no right to be consulted or require that their consent be obtained with respect to the Company's, Allenby's and/or Singer's conduct of the Placing.

All times and dates in this Announcement may be subject to amendment. Allenby or Singer shall notify Placees and any person acting on behalf of a Placee of any changes.

Persons who are invited to and who choose to participate in the Placing, by making an oral and legally binding offer to acquire Placing Shares, will be deemed to have read and understood this Announcement in its entirety and to be making such offer to acquire Placing Shares on the terms and conditions, and to be providing the representations, warranties, acknowledgements and undertakings, contained in this Appendix I.

In this Appendix I, unless the context otherwise requires, "Placee" means a Relevant Person (including individuals, funds or others) by whom or on whose behalf a commitment to take up Placing Shares has been given and who has been invited to participate in the Placing by Allenby or Singer.

Conditions of the Placing

The obligations of Allenby and Singer under the Placing Agreement are conditional, amongst other things, on:

• the Placing Shares and the Consideration Shares having been allotted, conditional only on Admission, by no later than 1.00 p.m. on 27 May 2025, or such later time and/or date as may be agreed between the Company, Allenby and Singer (each acting reasonably);
• the performance by the Company of its obligations under the Placing Agreement to the extent they fall to be performed on or prior to Admission;
• there not occurring, in the opinion of Allenby and Singer (acting in good faith), any material adverse change in, or any development reasonably likely to involve a prospective material adverse change in, the condition (financial, operational, legal or otherwise) or the earnings, business affairs or business prospects of the Group, taken as a whole, whether or not arising in the ordinary course of business and whether or not foreseeable at the date of the Placing Agreement; and
• Admission occurring not later than 8.00 a.m. on 27 May 2025 or such later time and/or date as Allenby and Singer may agree in writing with the Company (but in any event no later than 8.00 a.m. on 13 June 2025).

If (a) the Conditions of the Placing are not fulfilled (or, to the extent permitted under the Placing Agreement, waived by Allenby and Singer), or (b) the Placing Agreement is terminated in the circumstances specified below, the Placing will lapse and each Placee's rights and obligations hereunder shall cease and determine at such time and no claim may be made by a Placee in respect thereof. None of Allenby, Singer, the Company, any Allenby Affiliate, any Singer Affiliate nor any holding company of the Company, any subsidiary of the Company, any subsidiary of any such holding company, any branch, affiliate or associated undertaking of any such company nor any of their respective directors, officers and employees (each a "Solvonis Affiliate") 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 it may make as to whether or not to waive or to extend the time and/or date for the satisfaction of any condition in the Placing Agreement or in respect of the Placing generally.

By participating in the Placing, each Placee agrees that Allenby's and Singer's rights and obligations in respect of the Placing terminate, inter alia, in the circumstances described below under "Right to terminate under the Placing Agreement".

Right to terminate under the Placing Agreement

Allenby and/or Singer may, at any time before Admission and in its (or their) absolute discretion, terminate the Placing Agreement with immediate effect if, amongst other things:

• the Company has failed to comply with any of its obligations under the Placing Agreement which Allenby and Singer consider, in their absolute discretion (acting in good faith), to be material;
• any of the warranties given by the Company in the Placing Agreement is untrue and inaccurate in any respect or a matter arises which might reasonably be expected to give rise to a claim thereunder;
• any statement contained in the Placing Agreement or in this Announcement is, or has become, untrue, incorrect or misleading in any material respect;
• any of the conditions to the Placing Agreement has become incapable of fulfilment before, or has not been satisfied by, the latest date/time provided therein and has not been waived by Allenby and Singer; or
• there occurs a material adverse change, or certain force majeure events, the effect of which are such as to make it, in Allenby's and Singer's judgment (acting reasonably and in good faith), impracticable or inadvisable to market the Placing Shares and/or to proceed with the Placing in the manner contemplated or which may materially and adversely affect the success of the Placing.

By participating in the Placing, each Placee agrees with Allenby and Singer that the exercise by Allenby or Singer of any right of termination or other discretion under the Placing Agreement shall be within their absolute discretion and that neither Allenby nor Singer need make any reference to Placees in this regard and that, to the fullest extent permitted by law, neither the Company, Allenby, any Allenby Affiliate, Singer, any Singer Affiliate nor any Solvonis Affiliate shall have any liability whatsoever to any Placee in connection with any such exercise or failure to so exercise.

Registration and settlement

Settlement of transactions in the Placing Shares following Admission will take place within the CREST system, using the delivery versus payment ("DVP") mechanism, subject to certain exceptions. Allenby and Singer each reserves the right to require settlement for and delivery of the Placing Shares to Placees by such other means as they may deem necessary, including, without limitation, if delivery or settlement is not possible or practicable within the CREST system within the timetable set out in this Announcement or would not be consistent with the regulatory requirements in the Placee's jurisdiction.

The expected timetable and other details for settlement will be as follows:

Each Placee allocated Placing Shares in the Placing will be sent a trade confirmation stating the number of Placing Shares allocated to it, the Issue Price, the aggregate amount owed by such Placee to Allenby or Singer (as the case may be) and settlement instructions.

Placees should settle against the CREST ID shown in the trade confirmation. It is expected that such trade confirmation will be despatched on the expected trade date shown above. Each Placee agrees that it will do all such things as are necessary to ensure that delivery and payment is completed in accordance with either the standing CREST or certificated settlement instructions which it has in place with the applicable joint broker.

It is expected that settlement will take place on the Settlement Date shown above on a DVP basis in accordance with the instructions set out in the trade confirmation, unless otherwise notified by Allenby or Singer.

Interest is chargeable daily on payments not received from Placees on the due date in accordance with the arrangements set out above, in respect of either CREST or certificated deliveries, at the rate of two percentage points above the base rate of Barclays Bank plc as determined by Allenby and/or Singer.

Each Placee is deemed to agree that, if it does not comply with these obligations, Allenby and/or Singer (as the case may be) may sell any or all of the Placing Shares allocated to that Placee on such Placee's behalf and retain from the proceeds, for Allenby's or Singer's own account and profit, an amount equal to the aggregate amount owed by the Placee plus any interest due. The Placee will, however, remain liable for any shortfall below the aggregate amount owed by such Placee and it may be required to bear any stamp duty or stamp duty reserve tax (together with any interest or penalties) which may arise upon the sale of such Placing Shares on that Placee's behalf.

Insofar as Placing Shares are registered in the Placee's name or that of its nominee or in the name of any person for whom the 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 any levy, stamp duty or stamp duty reserve tax. If there are any circumstances in which any other stamp duty, stamp duty reserve tax or other similar taxes or duties (including any interest and penalties relating thereto) is payable in respect of the issue, allocation, transfer or delivery of the Placing Shares (or, for the avoidance of doubt, if any stamp duty or stamp duty reserve tax is payable in connection with any subsequent transfer of or agreement to transfer Placing Shares), neither Allenby, Singer nor the Company shall be responsible for the payment thereof. Allenby and Singer are each receiving corporate finance fees and certain commissions in respect of the Placing. Placees will not be entitled to receive any fee or commission in connection with the Placing.

• if it is a financial intermediary, as that term is used in Article 5(1) of the UK Prospectus Regulation: (a) any Placing Shares acquired by it in the Placing have not been acquired on behalf of, nor have they been acquired with a view to their offer or resale to, persons in the United Kingdom or to which the UK Prospectus Regulation otherwise applies other than UK Qualified Investors or in circumstances in which the prior consent of Allenby and Singer has been given to the offer or resale; or (ii) where Placing Shares have been acquired by it on behalf of persons in the United Kingdom other than UK Qualified Investors, the offer of those Placing Shares to it is not treated under the UK Prospectus Regulation as having been made to such persons;

• it (and any person acting on its behalf) has the funds to pay for the Placing Shares for which it has agreed to subscribe and it will pay for the Placing Shares acquired by it in accordance with this Announcement and with any trade confirmation sent to it by Allenby or Singer (or on their behalf) in respect of its allocation of Placing Shares and its participation in the Placing on the due time and date set out herein against delivery of such Placing Shares to it, failing which the relevant Placing Shares may be placed with other Placees or sold as Allenby or Singer may, in their absolute discretion, determine and it will remain liable for any shortfall below the net proceeds of such sale and the placing proceeds of such Placing Shares and may be required to bear any stamp duty or stamp duty reserve tax (together with any interest or penalties due pursuant to the terms set out or referred to in this Announcement) which may arise upon the sale of such Placee's Placing Shares on its behalf;
• none of Allenby, nor any Allenby Affiliate, Singer, nor any Singer Affiliate nor any person acting on their behalf is making any recommendations to it or advising it regarding the suitability or merits of any transaction it may enter into in connection with the Placing, and acknowledges that none of Allenby, nor any Allenby Affiliate, Singer, nor any Singer Affiliate nor any person acting on their behalf has any duties or responsibilities to it for providing advice in relation to the Placing or in respect of any representations, warranties, undertakings or indemnities contained in the Placing Agreement or for the exercise or performance of any of Allenby's or Singer's rights and obligations thereunder, including any right to waive or vary any condition or exercise any termination right contained therein;
• (i) the person whom it specifies for registration as holder of the Placing Shares will be (a) the Placee or (b) the Placee's nominee, as the case may be, (ii) none of Allenby, Singer nor the Company will be responsible for any liability to stamp duty or stamp duty reserve tax or other similar taxes or duties imposed in any jurisdiction (including interest and penalties relating thereto) resulting from a failure to observe this requirement and (iii) the Placee and any person acting on its behalf agrees to acquire the Placing Shares on the basis that the Placing Shares will be allotted to the CREST stock account of (as applicable) Allenby or Singer which will hold them as settlement agent and as nominee for the Placee until settlement in accordance with its standing settlement instructions with payment for the Placing Shares being made simultaneously upon receipt of the Placing Shares in the Placee's stock account on a delivery versus payment basis;

• any person who confirms to Allenby or Singer on behalf of a Placee an agreement to subscribe for Placing Shares and/or who authorises Allenby or Singer to notify the Placee's name to the Company's registrars, has authority to do so on behalf of the Placee;
• the agreement to settle each Placee's subscription for Placing Shares (and/or the subscription of a person for whom it is contracting as agent) free of stamp duty and stamp duty reserve tax depends on the settlement relating only to an acquisition by it and/or such person direct from the Company of the Placing Shares in question. Such agreement assumes that the Placing Shares are not being acquired in connection with arrangements to issue depositary receipts or to issue or transfer the Placing Shares into a clearance service. If there were any such arrangements, or the settlement related to other dealings in the Placing Shares, stamp duty or stamp duty reserve tax may be payable, for which none of the Company, Allenby nor Singer will be responsible. If this is the case, the Placee should take its own advice and notify Allenby and Singer accordingly;

The Placee acknowledges that the money will not be subject to the protections conferred by the FCA's client money rules; as a consequence, this money will not be segregated in accordance with those client money rules and will be used by Allenby or Singer (as the case may be) in the course of its business; and the Placee will rank only as a general creditor of Allenby or Singer (as the case may be);
• in order to ensure compliance with the Criminal Justice Act 1988, the Terrorism Act 2000, the Anti-Terrorism, Crime and Security Act 2001, the Proceeds of Crime Act 2002 (as amended) the Terrorism Act 2006, the Counter-Terrorism Act 2008 and the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 and, to the extent applicable, any related or similar rules or regulations of any body having jurisdiction in respect thereof and the Money Laundering Sourcebook of the FCA, Allenby, Singer (in each case solely for itself and as agent on behalf of the Company) or the Company's registrars may, in their absolute discretion, require verification of its identity. Pending the provision to Allenby, Singer or the Company's registrars, as applicable, of evidence of identity, definitive certificates in respect of the Placing Shares may be retained at Allenby's or Singer's absolute discretion (as the case may be) or, where appropriate, delivery of the Placing Shares to it in uncertificated form may be delayed at Allenby's, Singer's or the Company's registrars', as the case may be, absolute discretion. If within a reasonable time after a request for verification of identity, Allenby or Singer (in each case, for itself and as agent on behalf of the Company) or the Company's registrars have not received evidence satisfactory to them, Allenby, Singer and/or the Company may, at its absolute discretion, terminate its commitment in respect of the Placing, in which event the monies payable on acceptance of allotment will, if already paid, be returned without interest to the account of the drawee's bank from which they were originally debited;
• the Company, Allenby, Singer and others will rely upon the truth and accuracy of the foregoing representations, warranties, agreements, undertakings and acknowledgements;

• any document that is to be sent to it in connection with the Placing will be sent at its risk and may be sent to it at any address provided by it to Allenby or Singer (as the case may be);
• it will be bound by the terms of the Company's articles of association;
• these terms and conditions in this Appendix I and all documents into which this Appendix I is incorporated by reference or otherwise validly forms a part and/or any agreements entered into pursuant to these terms and conditions and all agreements to acquire shares pursuant to the Placing and/or any non-contractual obligations arising out of or in connection with any such agreements will be governed by and construed in accordance with the laws of England and Wales and it submits (on behalf of itself and on behalf of any person on whose behalf it is acting) to the exclusive jurisdiction of the courts of England and Wales in relation to any claim, dispute or matter arising out of any such agreement or obligation, except that enforcement proceedings in respect of the obligation to make payment for the Placing Shares (together with any interest chargeable thereon) may be taken by the Company, Allenby or Singer in any jurisdiction in which the relevant Placee is incorporated or in which any of its securities have a quotation on a recognised stock exchange;
• it is acting as principal only in respect of the Placing or, if it is acquiring the Placing Shares as a fiduciary or agent for one or more investor accounts, is duly authorised to do so and it has full power and authority to make, and does make, the foregoing representations, warranties, acknowledgements, agreements and undertakings on behalf of each such account; and

The acknowledgements, agreements, undertakings, representations and warranties referred to above are given to each of the Company, Allenby and Singer (for their own benefit and, where relevant, for the benefit of any Allenby Affiliate, Singer Affiliate and/or Solvonis Affiliate and any person acting on their behalf) and are irrevocable.

No claim shall be made against the Company, Allenby, any Allenby Affiliate, Singer, any Singer Affiliate, any Solvonis Affiliate or any other person acting on behalf of any such persons by a Placee (or any other person whether acting on behalf of a Placee or otherwise) to recover any damage, cost, loss, charge or expense which it may suffer or incur by reason of or arising from or in connection with the performance of its obligations hereunder or otherwise howsoever in connection with the Placing or Admission.

Any arrangements to issue or transfer the Placing Shares into a depositary receipts system or a clearance service or to hold the Placing Shares as agent or nominee of a person to whom a depositary receipt may be issued or who will hold the Placing Shares in a clearance service, or any arrangements subsequently to transfer the Placing Shares, may give rise to stamp duty and/or stamp duty reserve tax, for which none of the Company, Allenby nor Singer 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 stamp duty or stamp duty reserve tax undertakes to pay such stamp duty or stamp duty reserve tax forthwith and to indemnify on an after-tax basis and to hold harmless the Company, Allenby and Singer in the event that any of the Company or any Solvonis Affiliate or Allenby or any Allenby Affiliate or Singer or any Singer Affiliate has incurred any such liability to stamp duty or stamp duty reserve tax.

All times and dates in this Announcement may be subject to amendment. Allenby and/or Singer shall notify Placees and any person acting on behalf of a Placee of any such changes.

This Announcement has been issued by, and is the sole responsibility of, the Company.

Each Placee, and any person acting on behalf of a Placee, acknowledges that neither Allenby nor Singer owes any fiduciary or other duties to any Placee in respect of any representations, warranties, undertakings or indemnities in the Placing Agreement.

Allenby, which is authorised and regulated in the United Kingdom by the FCA, is acting for the Company and for no one else in connection with the Placing and will not regard any other person (whether or not a recipient of this Announcement) as a client in relation to the Placing or Admission and will not be responsible to anyone other than the Company for providing the protections afforded to clients of Allenby or for affording advice in relation to the Placing or Admission, or any other matters referred to herein.

Singer, which is authorised and regulated in the United Kingdom by the FCA, is acting for the Company and for no one else in connection with the Placing and will not regard any other person (whether or not a recipient of this Announcement) as a client in relation to the Placing or Admission and will not be responsible to anyone other than the Company for providing the protections afforded to clients of Singer or for affording advice in relation to the Placing or Admission, or any other matters referred to herein.

Each Placee and any person acting on behalf of a Placee acknowledges and agrees that Allenby or any Allenby Affiliate and Singer or any Singer Affiliate may, at their absolute discretion, agree to become a Placee in respect of some or all of the Placing Shares.

The rights and remedies of Allenby, Singer and the Company under these terms and conditions are in addition to any rights and remedies which would otherwise be available to each of them and the exercise or partial exercise of one will not prevent the exercise of others.

Each Placee may be asked to disclose in writing or orally to Allenby and/or Singer and, if so, undertakes to provide:

• if he is an individual, his nationality;
• such other "know your client" information as Allenby and/or Singer may reasonably request.

The price of shares and any income expected from them may go down as well as up and investors may not get back the full amount invested upon disposal of their shares. Past performance is not a guide to future performance, and persons needing advice should consult an independent financial adviser.
