Proposed use of proceeds

In order to maintain the progress that has been achieved in 2023, the Company is raising a minimum of £6 million with the key focus of the work programme being on the following:

· Laguna Verde Drilling Programme, £2.5m: Drill and test 5 new wells, 4 of which are resource wells and 1 being a re-injection well. The objective being to increase the JORC resource base, move resource from inferred to the measured & indicated categories and provide data from the re-injection well which will help inform the PFS. Continue the EIA, Hydrogeological and Metallurgical Studies to support the PFS and other technical requirements.

· Complete the Laguna Verde PFS, £1.0m: Intent is to complete in Q1 2024 the consideration of the project options and then take the preferred option into the DFS for completion by end 2024.

· DLE Pilot Plant, £1.1m: Commission and then operate the new plant to test and optimise the DLE process to help inform the PFS and produce lithium carbonate which can be sent to potential strategic partners for testing and product qualification.

· ASX Listing: Seek to complete the listing in late Q1 / early Q2 2024

· G&A and general working capital and fundraising costs, £1.4m

Aldo Boitano, Chief Executive Officer of CleanTech Lithium Plc, commented:

Background to the Fundraising

CleanTech Lithium is an exploration and development company, advancing the next generation of sustainable lithium projects in Chile. The target is to start producing battery grade lithium from 2026, with near zero carbon emissions and low environmental impact, offering the EV market a green lithium supply solution.

The Company was admitted to trading on AIM in March 2022, raised £5.6m through its IPO and raised a further £12.3m (before expenses) in a secondary placing in October 2022 to fund its planned work programme through 2023. The Company has previously confirmed that it plans to dual-list on the Australian Stock Exchange ("ASX") and due to delays in the regulatory application process in 2H 2023, it is now envisaged that this will take place in Q1 / early Q2 2024.

As the Company nears the end of 2023, it requires new funding to maintain progress on its main work programme activities in Chile and to meet its ongoing business costs. The Company has made significant progress in 2023 with the funds raised in late 2022, as highlighted below. Completion of the Laguna Verde PFS and ongoing production of lithium carbonate from the DLE pilot plant will allow the Company to begin to engage in strategic discussions with potential long term partners.

The Company's Assets

The Company's two main assets, the Laguna Verde and Francisco Basin projects, are in the lithium triangle, the world's centre for battery grade lithium production (the lithium triangle comprises Chile, Bolivia and Argentina). They are situated within basins entirely controlled by Cleantech Lithium, which affords significant potential development and operational advantages. The projects have direct access to excellent infrastructure and renewable power.

The Company also has two early exploration projects in Chile which offer additional upside potential. It holds 206 licences, totalling 605 km² located in the Pampa del Tamarugal basin, which constitute the Llamara project, and in Q2 2023 applied for 140 licences, totalling 337 km² located in the Salar de Atacama, which constitute the Salar de Atacama project. Being greenfield lithium projects, both the Llamara and Salar de Atacama licences provide the Company with additional exploration potential and if a lithium resource is ultimately generated, the potential to further utilise the DLE based processing method. CTL plans to undertake a programme of geophysical and exploration activities on these licences in due course, when funds allow for this.

Business Strategy

The Company's business strategy is focused on delivering long-term sustainable growth and returns for all stakeholders, built on three pillars:

· Develop the Company's prospective lithium projects (Laguna Verde, Francisco Basin, Llamara and Salar de Atacama) in Chile, prioritising Laguna Verde which is the most advanced project and can be brought into production first;

· Utilise clean technologies, including DLE and renewable energy, to produce sustainable battery grade lithium products; and

· Supply directly into the EV and battery market through strategic partnerships and/or offtake agreements.

Progress achieved since the last equity fundrasing

The Company has been extremely active since the last equity fundraising in October 2022, focused on continuing to de-risk its main assets and the application of its DLE technology in partnership with Sunresin and other specialist parties. Across its projects, the following has been undertaken and achieved since October 2022:

DLE Pilot Plant

The Company intends to use DLE technology to produce battery grade lithium, a technology that enables lower grade lithium brine deposits to be economically developed in a sustainable way greatly reducing the water consumption and land disturbance associated with the use of evaporation ponds. Using renewable energy will also greatly reduce carbon footprint compared to conventional hard rock mining. Since August 2022 the Company has been working under a memorandum of understanding with Sunresin New Materials Co. Ltd ("Sunresin") on the DLE extraction method having bought a small scale DLE laboratory scale unit from Sunresin and over the past six months using it to test various resins.

In early 2023, the Company ordered a US$2m pilot plant from a wholly owned subsidiary of Sunresin, Puritech, who are based in Belgium, and intend to produce 1 tonne per month of LCE in concentrated eluate from the plant. This will then be processed to battery grade lithium carbonate in an existing third party facility. The final components of the pilot plant have recently arrived in Chile and will be assembled and commissioned in the coming weeks with the assistance of technicians from Sunresin. It is planned that the plant will be operational before the end of 2023 with the targeted first production during Q1 2024.

Laguna Verde

· A further two exploration wells were drilled in 1H 2023, making a total of six wells to date. Capital spend on the 1H 2023 Laguna Verde drilling and testing campaign totalled approximately £2.25m and was within 3% of the approved budget.

· JORC-Compliant resource upgraded from 1.5 million tonnes to 1.8 million tonnes of lithium carbonate equivalent ("LCE") announced in July 2023, with a 39% increase in the Measured and Indicated category which will be used in the PFS to determine reserves and lithium production capacity.

· The results of the Laguna Verde Scoping Study were announced in January 2023, indicating robust economics based on a 30-year operational life of 20,000 tonnes lithium carbonate per annum, NPV8 of US$1.83bn at a long-term lithium price of US$22,500/tonne, IRR 45.1% and project payback 1 year 8 months.

· The PFS for Laguna Verde commenced in March 2023, with international consultant Worley and is targeted for completion end Q1 2024. This study will assess project alternatives and define a recommended project design to take into DFS. Project capital and operating costs will be determined. Completion of the PFS will allow CleanTech Lithium to engage in substantive discussions with potential strategic and offtake partners.

· Hydrogeological studies including well pump tests commenced to provide necessary data for the PFS.

· Environmental baseline studies commenced in April 2022 to provide four seasons of data to inform the Environmental Impact Assessment ("EIA") that will commence on completion of the PFS.

Francisco Basin

· In 1H 2023, the Company completed the three wells originally planned for the 2022 resource drill programme, while a further two wells were added to the programme. Capital spend on the 1H 2023 Francisco Basin drilling and testing campaign totalled approximately £3.1m and was 13% over the approved budget due to the addition of two wells.

· The drilling campaign resulted in the JORC-Compliant resource being upgraded from 0.53 million tonnes to 0.92 million tonnes of LCE, announced in August 2023, with around 42% of the resource being in the Indicated category. Further drilling was recommended in another campaign to increase the resource and move further resource into the measured & indicated categories.

· The Francisco Basin Scoping Study was announced in September 2023, indicating robust economics based on a 12-year operational life of 20,000 tonnes lithium carbonate per annum with NPV8 of US$1.1bn at a long-term lithium price of US$22,500/tonne, IRR 43.5% and project payback 2 year 7 months.

· Hydrogeological studies including well pump tests commenced to provide necessary data for the Scoping Study.

· Environmental baseline studies commenced in April 2022.

Llamara

· An initial scouting exploration programme was undertaken to test the lithium prospectivity of two targets, firstly a subsurface brine aquifer and secondly a surface evaporite mineral. First results were not positive but there were indications that lithium concentrations in the brine aquifer could increase with depth and the Company is evaluating the next stage of the exploration programme.

Salar de Atacama

· Applications lodged and now registered for new licences covering a total area of 337 km² in the Salar de Atacama basin, the leading lithium production base in the world.

· A geophysics programme has commenced with the first completed section identifying a subsurface brine aquifer target.

· The Salar de Atacama is designated as a strategic salar by the Chilean government - any commercial development will require a joint venture with a state entity holding a majority (51%) stake, which the Company views as suitable for such a strategically important basin.

Further work programme activities on the Francisco Basin, Llamara and Salar de Atacama will be subject to funding availability.

Special Contract for Lithium Operations (CEOLs)

The directors and senior management in Chile continue to maintain a highly active and positive dialogue with representatives of the Chile Government and relevant regulatory and government bodies and intend to obtain the required special contracts for lithium operations (CEOLs), as planned, to enable lithium production to commence at the Company's two advanced projects from 2026 onwards.

In Q3 2023, the Company's relevant subsidiaries submitted detailed special lithium CEOL applications for both Laguna Verde and Francisco Basin projects to the relevant authorities in Chile. CTL is the first company to have applied for CEOLs since the National Lithium Strategy was announced and, the Company understands, the applications have been positively received by the relevant authorities and other stakeholders. Whist there is no pre-defined timetable for approval by the authorities of the CEOLs, the Company hopes this could be achieved within six months of the applications.

Constitutional Changes

The proposed new constitution for Chile has been published and goes to national referendum on 17 December 2023. The proposed constitution does not alter the status of lithium which is currently non-concessionable and requires a CEOL to produce and sell lithium. Whether the proposed constitution is approved or rejected there will be no change to the requirement and the application process for a CEOL.

Community Relations

In line with the Company's ESG-focused strategy, collaborating with local communities is hugely important to the Company to ensure the Company is developing in a way that respects their concerns. The Directors believe their knowledge will continue to be of material importance to the Company as it moves forward with its projects. The Company has developed constructive relationships with the local communities across the Atacama region, engaging in open dialogue, transparency and recognising community knowledge to ensure the longevity of the Company's success and social licence to operate. The Company has also hosted visits from indigenous communities, most of which live in settlements approximately 100km away from the Company's two advanced projects.

ASX Listing and additional funding requirements

The Company announced its intention to dual-list on ASX in Q1 2023 and since then has engaged all the professional advisers required to undertake that in an efficient and effective manner. There are currently delays outside of the Company's control with this process but the CTL Board is still working to achieve the dual-listing as soon as possible, and it is now likely this will be delayed until Q1 / early Q2 2024.

The Company will need to raise additional funds to maintain its work programmes in Chile beyond March 2024, including the commencement of the DFS and EIA on Laguna Verde and continuance of the DLE pilot plant activities, etc. The Board plans to raise such funds in conjunction with the ASX listing or through other financing options that will be available at the time. The Board still believes listing on ASX will see a significant value uplift for CTL and also provide access to one of the deepest and most active pools of capital for mining companies.

In parallel to the ASX listing, the Company will also be looking to engage with potential strategic and offtake partners following completion of the PFS and commence substantive discussions on project participation and funding structures for the construction of the Laguna Verde project.

IMPORTANT INFORMATION FOR PLACEES ONLY REGARDING THE PLACING

Bookbuild

Following the release of this Announcement, the Joint Bookrunners will commence an accelerated bookbuilding process in respect of the Placing (the "Bookbuild") to determine demand for participation in the Placing by Placees. The books will open with immediate effect following release of this Announcement. Members of the public are not entitled to participate in the Placing. This Appendix gives details of the terms and conditions of, and the mechanics of participation in, the Placing.

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 absolute discretion, determine.

Information to Distributors

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 measures implementing retained EU law (as defined in section 6(7) of the European Union (Withdrawal) Act 2018) in the United Kingdom) ("Retained MiFID Provisions" (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 Placing Shares and Warrants have been subject to a product approval process, which has determined that such securities 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 the Retained MiFID Provisions; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II and the Retained MiFID Provisions (the "Target Market Assessment").

Notwithstanding the Target Market Assessment, distributors should note that: the price of the Placing Shares (and the Ordinary Shares that are subject to the Warrants) may decline and investors could lose all or part of their investment; the Placing Shares and Warrants offer no guaranteed income and no capital protection; and an investment in the Placing Shares and Warrants 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 Placing. Furthermore, it is noted that, notwithstanding the 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 Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II or the Retained MiFID Provisions; 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 Warrants and determining appropriate distribution channels.

Details of the Placing Agreement, the Placing Shares and the Warrants

The Joint Bookrunners are each acting as the Company's agent in connection with the Placing. The Joint Bookrunners have entered into an agreement with the Company (the "Placing Agreement") under which, subject to the conditions set out therein, including in respect of the Conditional Placing the passing by the shareholders of the Company of the Resolutions to approve the Conditional Placing, the Joint Bookrunners have agreed, as agents for the Company, severally to use their respective reasonable endeavours to procure Placees for the Placing Shares at a price of 22 pence per Placing Share (the "Issue Price") and as set out in the Placing Agreement. For every two Placing Shares subscribed for, the subscriber will also be granted one Warrant. Each Warrant will entitle the subscriber to subscribe for one Ordinary Share at a price of 33 pence per Ordinary Share at any time from the date Second Admission until 14 December 2026. The Warrants will be unlisted and no application will be made for the Warrants to be admitted to trading on AIM or any other stock exchange.

The Placing Shares and Warrants will be allotted and issued in two tranches:

· the Firm Placing, being a maximum of 14.12 million Placing Shares and 7.05 million Warrants (together, "Tranche 1") will be allotted and issued within the Company's existing authorities to allot equity securities; and

· the Conditional Placing, being the balance of the Placing Shares and Warrants subject to the Placing (together, "Tranche 2", and each of Tranche 1 and Tranche 2 being a "Tranche"), will be allotted and issued conditional upon (inter alia) approval of the Resolutions at a General Meeting of the Company's shareholders that it is intended will be convened to be held on or around 14 December 2024.

The number of Placing Shares and Warrants in the Placing will be determined following completion of the Bookbuild and set out in the placing supplement agreement to be entered into between Joint Bookrunners and the Company (the "Placing Supplement Agreement"). The final number of Placing Shares and Warrants and their allocations will be decided at the close of the Bookbuild. The timing of the closing of the Bookbuild will be at the discretion of the Company and the Joint Bookrunners. Details of the number of Placing Shares and Warrants will be announced as soon as practicable after the close of the Bookbuild.

Each Placee who agrees to subscribe for Placing Shares and Warrants in the Placing, and whose participation is confirmed by the Joint Bookrunners, will have their allocation of Placing Shares and Warrants split between Tranche 1 and/or Tranche 2 in such proportions as the Bookrunners may determine, in their absolute discretion.

The Company is also separately making the Open Offer of up to 2.37 million new Ordinary Shares. Qualified Shareholders who participate in the Open Offer will also be granted one Warrant for every two new Open Offer Shares subscribed for in the Open Offer. The Warrants to be granted under the Open Offer are being granted on the same terms as those granted under the Placing. Completion of the Placing is not conditional upon any minimum amount being raised under the Open Offer. The Open Offer is subject to shareholder approval at the General Meeting. The Open Offer is expected to close on or around 13 December 2023. The Open Offer Shares and associated Warrants will be allotted and issued as soon as practicable after the close of the General Meeting.

In accordance with the terms and subject to the conditions in the Placing Agreement, neither the Placing nor the Open Offer nor any potential subscription by certain of the Directors is being underwritten by the Joint Bookrunners or anyone else, and in the event that subscribers are not obtained for all or any of the Placing Shares, Open Offer Shares and Warrants or in the event of a default to make payment by any subscribers procured by the Joint Bookrunners, there will be no obligation on either Joint Bookrunner to subscribe for any Placing Shares, Open Offer Shares or Warrants.

The Placing Shares have been or will be duly authorised and will, when issued, be credited as fully paid and will 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 in respect of the Ordinary Shares after the date of issue of the Placing Shares. The Placing Shares and Warrants will be issued free of any encumbrances, liens or other security interests.

3. To bid in the Bookbuild, Placees should communicate their bid by telephone or in writing 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 acquire at the Issue Price. The Placing Shares carry a Warrant entitlement of one Warrant for every two Placing Shares.

5. Each Placee's allocation will be confirmed to Placees either orally or by email by the relevant Joint Bookrunner following the close of the Bookbuild. Subject to paragraph 8 below, the relevant Joint Bookrunner's oral 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 such Joint Bookrunner (as an agent of the Company) and the Company, under which such Placee agrees to subscribe for the number of Placing Shares and Warrants allocated to it in the respective Tranches and to pay the Issue Price for each such Placing Share on the terms and conditions set out in this Appendix and in accordance with the Company's articles of association.

6. Subject to paragraphs 2 and 3 above, the Joint Bookrunners may choose to accept bids, either in whole or in part, on the basis of allocations determined at their discretion and may scale down any bids for this purpose on such basis as they may determine or be directed.

The acceptance of offers shall be at the absolute discretion of the Joint Bookrunners. If within a reasonable time after a request for verification of identity, the Joint Bookrunners have not received such satisfactory evidence, the Joint Bookrunners may, in their absolute discretion, terminate the Placee's Placing participation in which event all funds delivered by the Placee to the Joint Bookrunners will be returned without interest to the account of the drawee bank or CREST account from which they were originally debited.

Each Placee will also have an immediate, separate, irrevocable and binding obligation, owed to the relevant Joint Bookrunner, to pay it (or its assignee or as it may direct) in cleared funds an amount equal to the product of the Issue Price and the number of Placing Shares that such Placee has agreed to acquire. Such Placees' obligations will be owed to the relevant Joint Bookrunner.

9. Except as required by law or regulation, no press release or other announcement will be made by any of the Joint Bookrunners 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.

In particular, neither of the Joint Bookrunners, nor the Company, nor any of their respective Affiliates shall have any responsibility or liability (including to the extent permissible by law, any fiduciary duties) in respect of the Joint Bookrunners' conduct of the Bookbuild or of such alternative method of effecting the Placing as the Joint Bookrunners, their respective Affiliates and the Company may agree or determine.

By participating in the Bookbuild, each Placee agrees that its rights and obligations hereunder terminate only in the circumstances described above and under "Termination of the Placing Agreement" below and will not be capable of rescission or termination by the Placee.

Termination of the Placing Agreement

By participating in the Placing, each Placee acknowledges and agrees that it has relied on its own investigation of the business, financial or other position of the Company in making an offer to participate in the Placing.

Post-Admission Undertakings

The Company has, inter alia, undertaken to the Joint Bookrunners that, except for the Placing Shares, the Open Offer Shares, Ordinary Shares subscribed by Directors in conjunction with the Placing, the Warrants and the Broker Warrants, the exercise of existing options and warrants, and certain issues of Ordinary Shares to Directors in lieu of fees, for six months following Admission of the Firm Placing Shares it will not issue any shares or other securities other than with the consent of the Nominated Adviser and the Joint Bookrunners (acting in good faith), and save for a further placing expected to be completed in the first half of 2024 as referred to in the Announcement or an investment by a strategic partner, provided that the Company notifies the Nominated Adviser and the Joint Bookrunners in advance of its intention to conduct such further placing.

By participating in the Placing, Placees agree that the exercise by the Nominated Adviser or the Joint Bookrunners of any power to grant consent to waive such undertaking by the Company shall be within the absolute discretion of the Nominated Adviser and the Joint Bookrunners and that they need not make any reference to, or consult with, Placees and that they shall have no liability to Placees whatsoever in connection with any such exercise of the power to grant consent.

Registration and settlement

Settlement of transactions in the Placing Shares (ISIN: JE00BPCP3Z37) and the Warrants (ISIN: JE00BLFDJM55) following Admission will take place within the relevant system administered by Euroclear ("CREST"), using the delivery versus payment mechanism, subject to certain exceptions. Subject to certain exceptions, the Joint Bookrunners and the Company reserve the right to require settlement for, and delivery of, the Placing Shares and Warrants to Placees by such other means that they deem necessary if delivery or settlement is not practicable in CREST within the timetable set out in this Announcement or would not be consistent with the regulatory requirements in the Placee's jurisdiction.

Each Placee agrees that it will do all things necessary to ensure that delivery and payment for any Placing Shares and Warrants is completed either (a) in accordance with either the standing CREST or certificated settlement instructions that it has in place with the relevant Joint Bookrunner; or (b) if there are no standing CREST of certificated settlement instructions in place with the relevant Joint Bookrunner, in accordance with such CREST or (if agreed with the Joint Bookrunners) certificated settlement instructions provided in writing by the Placee to the relevant Joint Bookrunner.

Subject to the paragraph below, the Company will deliver the relevant Placing Shares and Warrants in accordance with the Placing Agreement, to a CREST account operated by the relevant Joint Bookrunner as agent for the Company and each Joint Bookrunner will enter its delivery (DEL) instruction into the CREST system. The Joint Bookrunners will hold any Placing Shares and Warrants delivered to this account as nominee for the relevant Placees procured by it. 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 agreed in advance between a Placee ("Certificated Placee") and the relevant Joint Bookrunner, and notified in advance by the relevant Joint Bookrunner to the Company, the Company will (subject to the remainder of this paragraph) arrange for delivery of a share certificate and/or warrant certificate in the name of the Certificated Placee for the relevant Placing Shares and/or Warrants. Funds must be received by the relevant Joint Bookrunner from the Certificated Placees at least three days prior to the date of Admission of the relevant Tranche of Placing Shares. Subject to receipt of the relevant funds by the relevant Joint Bookrunner and subject and conditional upon Admission of the relevant Tranche of Placing Shares and grant of the relevant Tranche of Warrants, the Company shall arrange for delivery of the relevant share certificate and/or warrant certificate to the relevant Certificated Placee. In the event that Admission of the relevant Tranche of the Placing Shares and/or grant of the relevant Tranche of Warrants does not become effective by the Long Stop Date, any funds received by the Joint Bookrunners from any Certificated Placee shall be returned, without interest, to the relevant drawee bank account.

It is expected that settlement of:

· the Firm Placing Shares and Tranche 1 of the Warrants will be on 27 November 2023; and

· the Conditional Placing Shares and Tranche 2 of the Warrants will be on 15 December 2023,

in each case on a T+3 basis in accordance with the instructions given by the Joint Bookrunners.

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 Barclays Bank PLC as determined by the Joint Bookrunners, with interest compounded on a daily basis.

Each Placee agrees that, if it does not comply with these obligations, the Joint Bookrunners may sell any or all of the Placing Shares and Warrants allocated to that Placee on such Placee's behalf and retain from the proceeds, for the Company's account and benefit, an amount equal to the aggregate amount owed by the Placee plus any interest due. The relevant Placee will, however, remain liable for any shortfall below the aggregate amount owed by it and shall be required to bear any stamp duty, stamp duty reserve tax or other stamp, securities, transfer, registration, execution, documentary or other similar impost, duty or tax (together with any interest or penalties) which may arise upon the sale of such Placing Shares and Warrants on such Placee's behalf. The foregoing is without prejudice to any cause of action the Joint Bookrunners may have against a defaulting Placee.

If Placing Shares and/or Warrants are to be delivered to a custodian or settlement agent, Placees should ensure that the custodian or settlement agent is notified immediately to the relevant person within that organisation. Insofar as Placing Shares and/or Warrants 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 and/or Warrants should, subject to as provided below, be so registered free from any liability to United Kingdom stamp duty or United Kingdom stamp duty reserve tax. If there are any circumstances in which any other stamp duty or stamp duty reserve tax (and/or any interest, fines or penalties relating thereto) is payable in respect of the allocation, allotment, issue or delivery of the Placing Shares and/or Warrants (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 or Warrants), neither of the Joint Bookrunners nor the Company shall be responsible for the payment thereof. Placees will not be entitled to receive any fee or commission in connection with the Placing.

The foregoing acknowledgements, agreements, undertakings, representations, warranties and confirmations are given for the benefit of the Company as well as each of the Joint Bookrunners (for their own benefit and, where relevant, the benefit of their respective Affiliates and any person acting on their behalf) and are irrevocable. Each Placee, and any person acting on behalf of a Placee, acknowledges that neither of the Joint Bookrunners or the Company owe any fiduciary or other duties to any Placee in respect of any representations, warranties, undertakings or indemnities in the Placing Agreement.

Please also note that the agreement to allot and issue Placing Shares and grant Warrants to Placees (or the persons for whom Placees are contracting as nominee or agent) free of UK stamp duty and UK stamp duty reserve tax relates only to their allotment and issue to Placees, or such persons as they nominate as their agents or nominees, direct from the Company for the Placing Shares and Warrants in question. None of the Company or the Joint Bookrunners will be responsible for any UK stamp duty or UK stamp duty reserve tax or any other transfer taxes (including any interest, fines and penalties relating thereto) arising in relation to the Placing Shares and Warrants in any other circumstances.

Such agreement is subject to the representations, warranties and further terms above and also assumes, and is based on a warranty from each Placee, that the Placing Shares and Warrants are not being acquired in connection with arrangements to issue depositary receipts or to issue or transfer the Placing Shares and Warrants into a clearance service. Neither of the Joint Bookrunners nor the Company are liable to bear any stamp duty or stamp duty reserve tax or any other similar duties or taxes ("transfer taxes") or related interest, fines or penalties that arise (i) if there are any such arrangements (or if any such arrangements arise subsequent to the acquisition by Placees of Placing Shares and Warrants) or (ii) on a sale of Placing Shares and Warrants, or (iii) otherwise than under the laws of the United Kingdom. Each 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 and Warrants has given rise to such transfer taxes undertakes to pay such transfer taxes forthwith, and agrees to indemnify on an after-tax basis and hold the Joint Bookrunners, the Company, their respective Affiliates and any person acting on any of their respective behalf harmless from any such transfer taxes, and all interest, fines or penalties in relation to such transfer taxes. Each Placee should, therefore, take its own advice as to whether any such transfer tax liability arises.

Each Placee and any person acting on behalf of each Placee acknowledges and agrees that either Joint Bookrunners or any of their respective Affiliates may, at their absolute discretion, agree to become a Placee in respect of some or all of the Placing Shares and Warrants. Each Placee acknowledges and is aware that the Joint Bookrunners are receiving a fee in connection with their role in respect of the Placing as detailed 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 any of the Joint Bookrunners on behalf of the Placee and/or any person acting on behalf of the Placee may 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 may not be segregated from the Joint Bookrunners' money in accordance with the client money rules and may be used by the Joint Bookrunners in the course of its own business, and the Placee may rank only as a general creditor of the Joint Bookrunners.

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

No statement in the Placing Documents is intended to be a profit forecast or estimate, and no statement in the Placing Documents should be interpreted to mean that earnings per share of the Company for the current or future financial years would necessarily match or exceed the historical published earnings per share of the Company. Past performance is no guide to future performance and persons needing advice should consult an independent financial adviser.

The rights and remedies of the Nominated Adviser, Joint Bookrunners 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 the Joint Bookrunners:

a) if he or she is an individual, his or her nationality; or

b) if he or she is a discretionary fund manager, the jurisdiction in which the funds are managed or owned.
