Helium One Global Ltd

("Helium One" or "the Company")

Proposed Placing and Subscription of a minimum of £5.8 million (approximately US$7.4 million) to Fund a Second Exploration Well in the Rukwa Basin

Helium One Global (AIM: HE1), the primary helium explorer in Tanzania, is pleased to announce a proposed fundraise of £5.8 million (approximately US$7.4 million), before expenses, by way of a placing (the "Placing") and a direct subscription (the "Subscription") at a price of 0.25 pence per new ordinary share (the "Issue Price") (together, the "Fundraise").

The Placing is being conducted through an accelerated bookbuild process (the "Bookbuild") to be undertaken by Liberum Capital Limited ("Liberum"), and Peterhouse Capital Limited ("Peterhouse") acting as Joint Bookrunners (together the "Joint Bookrunners"). The Bookbuild will commence immediately following the release of this announcement.

The final number of shares to be issued pursuant to the Fundraise (the "Fundraise Shares") will be announced as soon as reasonably practicable after the close of the Bookbuild.

The Fundraise will be effected by way of a cashbox placing of new Ordinary Shares in the Company for non-cash consideration, further details of which are set out below. The cashbox placing structure is being used so as to enable the Fundraise to complete as quickly as possible and in any event before the Company commences drilling of the Itumbula West-A well which is currently scheduled for January 2024.

Summary

· Proposed Placing and Subscription to raise gross proceeds of a minimum £5.8 million (approximately US$7.4 million) (before expenses) at the Issue Price.

· The Placing will be made to certain existing shareholders and other institutional and high net worth investors.

· All of the directors of the Company and a member of management have indicated an intention to participate in the Subscription up to an aggregate amount of approximately £18k (approximately US$23k).

· Issue Price of 0.25 pence per new ordinary share represents a discount of 72 per cent. to the closing mid-market price of the Company's existing ordinary shares on 19 December 2023, the last practicable date prior to this announcement.

· The net proceeds of the Fundraise will be used for drilling an exploration well (Itumbula West-A) on the Itumbula prospect, in addition to general working capital purposes.

· The timing for the close of the Bookbuild and allocation of the Fundraise Shares shall be at the discretion of the Joint Bookrunners, in consultation with the Company. For the avoidance of doubt, the Fundraise is not underwritten.

The Placing is conditional upon, amongst other things, Admission becoming effective and the placing agreement between the Company and the Joint Bookrunners becoming unconditional and not being terminated in accordance with its terms.

Further details of the terms and conditions of the Placing are set out in the Appendix to this announcement (which forms part of this announcement, such announcement and its Appendices together being the "Announcement").

The Appendix to this announcement (which forms part of this announcement) contains the detailed terms and conditions of the Placing. Members of the public are not eligible to take part in the Placing.

Lorna Blaisse, Chief Executive Officer, commented:

"The Itumbula prospect has always ranked highly in our portfolio. We are confident that the rig will be fully operational again shortly. We're currently rigging up and due to remobilise a full crew and then we will spud the Itumbula West-A well. With the dataset we have, as well as the information that we have gained from Tai-3, we remain optimistic that this well will yield a very positive outcome."

Notes to Editors

Helium One Global, the AIM-listed Tanzanian explorer, holds prospecting licences totalling 2,965km2 across three distinct project areas, with the potential to become a strategic player in resolving a supply-constrained helium market.

The Rukwa, Balangida, and Eyasi projects are located within rift basins on the margin of the Tanzanian Craton in the north and southwest of the country. The assets lie near surface seeps with helium concentrations ranging up to 10.6% He by volume. All Helium One's licences are held on a 100% equity basis and are in close proximity to the required infrastructure.

The Company's flagship Rukwa Project is located within the Rukwa Rift Basin covering 1,898km2 in south-west Tanzania. The project is considered to be an advanced exploration project with leads and prospects defined by a subsurface database including multispectral satellite spectroscopy, airborne gravity gradiometry, 2D seismic data, and QEMSCAN analysis. The Rukwa Project has been de-risked by the 2021 drilling campaign, which identified reservoir and seal with multiple prospective intervals from basin to near surface within a working helium system.

In July 2023, Helium One acquired their own exploration drill rig, an Epiroc Predator 220 oil and gas type rig, capable of drilling to depths of 2,400m. The rig was shipped to Tanzania in order to commence Phase II drilling operations.

Helium One is listed on the AIM market of the London Stock Exchange with the ticker of HE1 and on the OTCQB in the United States with the ticker HLOGF.

Background to and reasons for the Fundraise and Use of Proceeds

Itumbula West-A well: New prospect and revised well location

Following the positive drilling results from the Tai-3 well, and the increase in concentration and frequency of helium shows encountered with increased depth as well as the proximity to faults and fractures in Basement, the Company has subsequently reviewed the geology of the Itumbula prospect. It is bounded by a large, deep seated western fault which extends into the Basement source rock. It is this fault that is interpreted to be associated with the active surface helium seep, located approximately 3km from the proposed well location.

With the results from Tai-1/-1A and Tai-3 indicating that it could be the migration of fluids that play a crucial role in liberating the helium out of the Basement source rock and along fractures and faults. The Company has now elected to target the western bounding fault at Itumbula in addition to the conventional targets in the Lake Beds, Karoo and Basement. Therefore, the Itumbula well has been designed to directly target this new, additional fault play where the Company anticipates helium concentrations will be significantly elevated.

Operational readiness

As previously announced by the Company, the civils work on the new Itumbula West-A well pad is now complete and the rig and camp have also been moved to Itumbula from the Tai-3 location. The rig and all associated equipment (including the substructure, pipe skate, wireline equipment, cementing and fluids) are now on the Itumbula West-A well site and the rigging-up process has commenced. The iron rough neck, which arrived on location on 14th December, will be installed as part of the rig-up process. Following this, the rig will undergo a full function test and, once this process is complete, and all personnel have been remobilised, the Company will commence drilling.

Rationale for the Fundraise

The proposed Fundraise will provide the Company with the opportunity to drill a second exploration well and meet the outstanding costs from Tai-3 as a result of rig repairs, drilling a deeper well than originally planned as well as new civils work for a revised well location on Itumbula. The Itumbula West-A well provides an opportunity to drill a highly ranked prospect into a new fault play, as well as targeting the Lake Beds, Karoo and Basement play. The new well is located, ~3km from the active Itumbula surface helium seep, with helium concentrations measured up to 10.2%, as well as the presence of multiple surface helium anomalies which have been identified across the prospect from multispectral satellite spectroscopy studies.

Use of proceeds

The net proceeds of the Fundraise provide the Company funds for drilling the Itumbula West-A well, commencing in early January 2024, with the breakdown of the use of proceeds for the full drilling programme including:

· Drilling of Itumbula West-A ($6.1m)*

· Tai-3 outstanding costs ($2.7m)

· Licence fees ($0.3m)

· Estimated cost of fundraise ($0.7m)

· 3 months G&A ($0.8m)

*Cost of drilling Itumbula West-A assumes an uninterrupted c.30 day drilling programme with no operational cost overruns

The Company also currently has a cash balance of $3.2m.

Drilling Programme and related timetable

Following the completion of the proposed Fundraise, the Company will be fully funded to complete an uninterrupted 30 day drilling programme of the Itumbula West-A well.

Outlook and Working Capital Position

Following the completion of the Tai-3 well drilling programme, the Company retains sufficient funds to remain a going concern, with a current cash balance of $3.2m. The proceeds of the Fundraise will provide up to an additional 3 months working capital including the drilling of the Itumbula West-A well.

Details of the Placing and Subscription

The Fundraise Shares will, when issued, be credited as fully paid and will rank pari passu in all respects with Helium One's existing issued ordinary shares of no par value each (the "Ordinary Shares").

The Placing, which is subject to the terms and conditions set out in the Appendix to this Announcement, is conditional upon, inter alia, Admission becoming effective and the Placing Agreement (defined below) becoming unconditional in all respects by no later than 8.00 a.m. on 28 December 2023 or such later time and/or date (being not later than 31 January 2024) as the Company, Liberum and Peterhouse may agree. Application will be made to the London Stock Exchange for the Fundraise Shares to be admitted to trading on AIM. It is expected that Admission will occur and that dealings will commence at 8.00 a.m. on 28 December 2023.

The Fundraise will be effected by way of a cashbox placing of new Ordinary Shares in the Company for non-cash consideration. Liberum, Peterhouse, the direct subscribers under the Subscription will subscribe for redeemable preference shares in a new Jersey incorporated wholly owned subsidiary of the Company ("JerseyCo") for an amount equal to the net proceeds of the Fundraise respectively. The Company will allot and issue the Fundraise Shares on a non-pre-emptive basis to Placees, subscribers pursuant to the Subscription in consideration for the transfer of the redeemable preference shares in JerseyCo that will be issued to Liberum, Peterhouse, the direct subscribers under the Subscription. No shareholder approval is required to effect the Fundraise.

Liberum and Peterhouse are acting as Joint Bookrunners to the Placing.

Liberum and Peterhouse have entered into an agreement with Helium One (the "Placing Agreement") under which, subject to the conditions set out therein, Liberum and Peterhouse have agreed to use their respective reasonable endeavours to procure subscribers for the Placing shares in the UK. The Placing for placees of Liberum and Peterhouse are subject to the terms and conditions set out in the Appendix to this announcement.

Admission and Settlement

Application will be made for the Fundraise Shares to be admitted to trading ("Admission") on the AIM market of the London Stock Exchange ("AIM"). It is expected that Admission will take place at 8.00 a.m. (London time) on or around 28 December 2023 (or such later date as may be agreed between the Company and the Joint Bookrunners). The Placing is conditional upon, inter alia, Admission becoming effective and the Placing Agreement not being terminated in accordance with its terms. The Subscription is also conditional, inter alia, upon the Placing becoming unconditional.

Bookbuild process

Following the release of this Announcement, the Joint Bookrunners will commence a bookbuild process in respect of the Placing (the "Bookbuild") to determine demand for participation in the Placing by Placees. The book will open with immediate effect following release of this Announcement.

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.

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.

Principal terms of the Bookbuild and Placing

1 Liberum and Peterhouse are acting as joint bookrunners in connection with the Placing, severally, and not jointly, nor jointly and severally, as agents of the Company.

2 Participation in the Placing will only be available to persons who may lawfully be, and are, invited by the Joint Bookrunners to participate. The Joint Bookrunners and any of their respective Affiliates are entitled to enter bids in the Bookbuild.

3 The number of the Placing Shares will be established in the Bookbuild and announced by the Company through a Regulatory Information Service (the "Placing Results Announcement") following the completion of the Bookbuild and the entry into the Placing Term Sheet by the Company and the Joint Bookrunners. The Joint Bookrunners and the Company reserve the right to increase the amount to be raised and the number of Placing Shares to be issued pursuant to the Placing in their absolute discretion.

4 The number of Placing Shares and the aggregate proceeds to be raised through the Placing will be agreed between the Joint Bookrunners and the Company following completion of the Bookbuild.

5 To bid in the Bookbuild, Placees should communicate their bid by telephone to their usual sales contact at the relevant Joint Bookrunner. Each bid should state the number of Placing Shares which a prospective Placee wishes to subscribe for at the Placing Price. Bids may be scaled down by the Joint Bookrunners on the basis referred to in paragraph 10 below.

6 The Bookbuild is expected to close no later than 8.00 a.m. on 21 December 2023 but may be closed earlier or later at the absolute discretion of the Joint Bookrunners. The Joint Bookrunners may, in agreement with the Company, accept bids that are received after the Bookbuild has closed. The Company reserves the right (in consultation with the Joint Bookrunners) to reduce or seek to increase the amount to be raised pursuant to the Placing, in its discretion.

7 The Joint Bookrunners shall, in consultation with the Company, agree all allocation matters in respect of the Placing in accordance with the terms of the Placing Agreement and will be confirmed orally or in writing by the relevant Joint Bookrunner, acting as agent of the Company, to the Placees. The relevant Joint Bookrunner's oral or written confirmation of an allocation to such Placee will give rise to a legally binding commitment by such person (who will at that point become a Placee), in favour of the relevant Joint Bookrunner and the Company, under which such Placee agrees to subscribe for the number of Placing Shares allocated to it and to pay the Placing Price for each such Placing Share on the terms and subject to the conditions set out in this Appendix and in accordance with the Company's memorandum and articles of association.

8 The Company will release the Placing Results Announcement following the close of the Bookbuild, detailing the aggregate number of the Placing Shares to be issued.

9 Each Placee's allocation and commitment will be evidenced by a contract note or electronic confirmation issued to such Placee by the relevant Joint Bookrunner. A bid in the Bookbuild will be made on the terms, and subject to, the conditions in this Appendix and the terms of this Appendix will be deemed incorporated into the contract note, the form of which will be dispatched to each Placee as soon as possible after its allocation of Placing Shares has been confirmed orally or in writing to it by the relevant Joint Bookrunner.

10 Subject to paragraphs 6, 7 and 8 above, each of 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 Joint Bookrunners may also, notwithstanding paragraphs 6, 7 and 8 above, after consultation with the Company, allocate Placing Shares after the:

(a) time of any initial allocation to any person submitting a bid after that time; and

(b) Bookbuild has closed to any person submitting a bid after that time,

and 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.

11 A bid in the Bookbuild will be made on the terms, and subject to, the conditions in this Appendix and will be legally binding on the Placee on behalf of which it is made and except with the relevant Joint Bookrunner's consent will not be capable of variation or revocation after the time at which it is submitted. Each Placee will also have an immediate, separate, irrevocable and binding obligation, owed to the relevant Joint Bookrunner and the Company, to pay to it (or as it may direct) in cleared funds an amount equal to the product of the Placing Price and the number of Placing Shares such Placee has agreed to acquire and the Company has agreed to allot and issue to that Placee. The Company shall allot such Placing Shares to each Placee following each Placee's payment to the relevant Joint Bookrunner of such amount.

12 The Placing Shares are not being offered and sold by the Company except in accordance with Regulation S or pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. The Placee and the prospective beneficial owner of the Placing Shares is, and at the time the Placing Shares are subscribed for will be: (a) outside the United States and subscribing for the Placing Shares in an "offshore transaction" as defined in, and pursuant to, Regulation S; or (b) (i) subscribing for the Placing Shares pursuant to an exemption from the registration requirements under the US Securities Act.

13 Except as required by law or regulation, no press release or other announcement will be made by 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.

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

15 All obligations under the Bookbuild and Placing will be subject to fulfilment of the Conditions referred to below under "Conditions of the Placing" and to the Placing not being terminated on the basis referred to below under "Termination of the Placing".

16 By participating in the Bookbuild, 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.

17 To the fullest extent permissible by law, none of:

(a) the Joint Bookrunners;

(b) any of their respective Affiliates; nor

(c) to the extent not contained within (a) or (b) above, any person connected with the Joint Bookrunners as defined in the FSMA ((b) and (c) being together Affiliates and individually an Affiliate of the Joint Bookrunners),

shall have any responsibility or liability (including to the extent permissible by law, any fiduciary duties) to Placees or to any other person whether acting on behalf of a Placee or otherwise. In particular, none of the Joint Bookrunners, nor the Company, nor any of their respective Affiliates nor any of its or their agents, directors, officers or employees shall have any 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 and the Company may agree or determine.

Registration and settlement of the Placing Shares

If Placees are allocated any Placing Shares in the Placing they will be sent a contract note or electronic trade confirmation which will confirm the number of Placing Shares allocated to them at the Placing Price and the aggregate amount owed by them to the relevant Joint Bookrunner.

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

Settlement of transactions in the Placing Shares (ISIN: VGG4392T1075) placed by the Joint Bookrunners following Admission will take place within CREST, subject to certain exceptions. Settlement of the Placing Shares through CREST will be on a T+3 basis unless otherwise notified by any Joint Bookrunner and is expected to occur on 28 December 2023 in accordance with the contract note or electronic trade confirmation.

Settlement will be on a delivery versus payment basis. However, in the event of any difficulties or delays in the admission of the Placing Shares to CREST or the use of CREST in relation to the Placing, the Company and the Joint Bookrunners may agree that the Placing Shares should be issued in certificated form. Each of the Joint Bookrunners reserves the right to require settlement for the Placing Shares, and to deliver the Placing Shares to Placees, by such other means as they deem necessary if delivery or settlement to Placees is not practicable within the CREST system or would not be consistent with regulatory requirements in a Placee's jurisdiction.

General

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 prevailing base rate of Barclays Bank plc as determined by the Joint Bookrunners.

Each Placee is deemed to agree that if it does not comply with these obligations, the relevant Joint Bookrunner may sell any or all of the Placing Shares allocated to that Placee on their behalf and retain from the proceeds, for the Company's own 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 Placing Price and for any stamp duty or stamp duty reserve tax (together with any interest or penalties) which may arise upon the sale of its Placing Shares on its behalf.

By communicating a bid for Placing Shares, such Placee confers on the Joint Bookrunners all such authorities and powers necessary to carry out such sale and agrees to ratify and confirm all actions which the Joint Bookrunners lawfully take in pursuance of such sale.

If Placing Shares are to be delivered to a custodian or settlement agent, Placees must ensure that, upon receipt, the conditional contract note is copied and delivered immediately to the relevant person within that organisation. Insofar as Placing Shares are registered in a Placee's name or that of its nominee or in the name of any person for whom a Placee is contracting as agent or that of a nominee for such person, such Placing Shares should, subject as provided below, be so registered free from any liability to United Kingdom stamp duty or stamp duty reserve tax. Placees will not be entitled to receive any fee or commission in connection with the Placing.

Conditions of the Placing

The obligations of the Joint Bookrunners under the Placing Agreement are, and the Placing is, conditional upon, inter alia:

18 Admission of the Placing Shares becoming effective by no later than 8.00 a.m. on 28 December 2023 (or such later time and / or date as the Company and the Joint Bookrunners shall agree, not being later than 8.00 a.m. on the Long Stop Date);

19 the delivery by the Company to the Joint Bookrunners of certain documents required under the Placing Agreement;

20 the Company having fully performed its obligations under the Placing Agreement to the extent that such obligations fall to be performed prior to Admission of the Placing Shares;

21 the warranties on the part of the Company contained in the Placing Agreement being true and accurate and not misleading on and as of the date of the Placing Agreement, the date of the Placing Term Sheet and at all times during the period up to and including Admission;

22 the publication by the Company of the Placing Results Announcement through a Regulatory Information Service by not later than 8:00 am on the Business Day following the date of Placing Agreement or such other time and/or date as may be agreed between the Company and the Joint Bookrunners;

23 there having been since the date of Placing Agreement no Material Adverse Change (whether or not foreseeable at the date of Placing Agreement);

24 the Company issuing, conditional only on Admission, the Placing Shares; and

25 Admission occurring not later than 8:00 am on 28 December 2023 or such other time and/or date as may be agreed between the Company and the Joint Bookrunners, not being later than 8:00 am on the Long Stop Date,

(together, the "Conditions").

If: (a) any of the Conditions are not fulfilled or waived by the Joint Bookrunners (acting jointly) by the respective time or date where specified (or such later time or date as the Company and the Joint Bookrunners may agree, save that such time shall not be extended beyond 8.00 a.m. on the Long Stop Date); (b) any of such Conditions becomes incapable of being fulfilled; or (c) the Placing Agreement is terminated in the circumstances specified below, the Placing in relation to the Placing Shares will lapse and the Placee's 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 against either the Company or any of the Joint Bookrunners in respect thereof.

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

The Joint Bookrunners may (in consultation with the Company), in their absolute discretion (acting jointly) and upon such terms as each of them thinks fit, waive fulfilment of all or any of the Conditions in the Placing Agreement in whole or in part, or extend the time provided for fulfilment of one or more Conditions, save that certain Conditions (including the condition relating to Admission) may not be waived. Any such extension or waiver will not affect Placees' commitments as set out in this Appendix. The Joint Bookrunners may each terminate the Placing Agreement in certain circumstances, details of which are set out below.

None of the Joint Bookrunners nor any of their respective Affiliates nor the Company 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 any of them 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 any of them may make as to the satisfaction of any Condition, the number of Placing Shares to be placed 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 each Joint Bookrunner.

The issue of the Placing Shares is to be effected by way of a cash box placing. In accordance with the Placing Agreement, a subscription and transfer agreement entered into between the Company, Helium One Jersey Finance Limited (a Jersey incorporated subsidiary of the Company) ("JerseyCo"), Liberum and Peterhouse, the Company will allot and issue the Placing Shares on a non pre-emptive basis to Liberum and/or Peterhouse, as bare nominees for the Placees (pending transfer of legal title to the Placees through CREST), in consideration for the transfer to the Company by Liberum and/or Peterhouse of certain shares which it holds in JerseyCo. Accordingly, instead of receiving cash as consideration for the issue of the Placing Shares, the Company will, conditional on Admission and following the conclusion of the Placing, own all of the issued share capital of JerseyCo, whose only assets will be (i) cash, representing an amount approximately equal to proceeds of the Placing and Subscription (net of commissions, fees and expenses paid by JerseyCo on behalf of the Company to the Joint Bookrunners) and (ii) an intercompany receivable due from the Company in respect of the commissions, fees and expenses paid by JerseyCo on behalf of the Company. By taking up or purchasing Placing Shares under the Placing and submitting a valid payment in respect thereof, a Placee instructs Liberum and/or Peterhouse (as applicable) to hold such payment and: (i) to the extent of a successful application under the Placing, to apply such payment on behalf of Liberum and/or Peterhouse for Liberum and/or Peterhouse to subscribe for redeemable preference shares in JerseyCo; and (ii) to the extent of an unsuccessful application under the Placing, Liberum and/or Peterhouse to return the relevant payment without interest to the applicant.

Termination of the Placing

Each Joint Bookrunner is entitled to terminate the Placing Agreement in accordance with its terms in certain circumstances, including, inter alia, if at any time before Admission a Joint Bookrunner becomes aware that:

1 Any material statement contained in this document and any other documents to be issued by the Company in connection with the Placing is incorrect or has become or been discovered to be untrue, inaccurate or misleading or that there has been an omission therefrom; or

2 in the opinion of either of the Joint Bookrunners (acting in good faith), any of the warranties of the Company contained in the Placing Agreement was, when given, untrue, inaccurate or misleading or are not true and accurate or have become misleading by reference to the facts subsisting at the time in any material respect; or

3 in the opinion of either of the Joint Bookrunners (acting in good faith), the Company has failed to comply with any of its material obligations contained in the Placing Agreement; or

5 in the opinion of either of the Joint Bookrunners (acting in good faith), there has occurred, in a Joint Bookrunner's opinion, a Material Adverse Change;

7 there has occurred a suspension (or cancellation by the London Stock Exchange of trading in the Company's securities.

On the occurrence of any one or more of the above-mentioned circumstances, the Joint Bookrunners may, in their absolute discretion, by notice to the Company, terminate the Placing Agreement with immediate effect.

If the Placing Agreement is terminated in accordance with its terms, the rights and obligations of each Placee in respect of the Placing as described in this Announcement shall cease and terminate at such time and no claim can be made by any Placee in respect thereof.

Any termination by one Joint Bookrunner of its rights under the Placing Agreement shall be without prejudice to the obligations and rights of the other Joint Bookrunners and the Placing Agreement shall continue in full force and effect. No consents or approvals in respect of the Placing shall be required of any Joint Bookrunner who has terminated its rights under the Placing Agreement.

By participating in the Bookbuild, each Placee agrees with the Company and the Joint Bookrunners that the exercise by the Company or the Joint Bookrunners of any right of termination or any other right or other discretion under the Placing Agreement shall be within the absolute discretion of the Company or the Joint Bookrunners or for agreement between the Company and the Joint Bookrunners (as the case may be) and that neither the Company nor the Joint Bookrunners need make any reference to such Placee and that none of the Company, the Joint Bookrunners, nor any of their respective Affiliates shall have any liability to such Placee (or to any other person whether acting on behalf of a Placee or otherwise) whatsoever in connection with any such exercise.

By participating in the Placing, each Placee agrees that its rights and obligations terminate only in the circumstances described above and under the "Conditions of the Placing" section above and will not be capable of rescission or termination by it after oral or written confirmation by the Joint Bookrunners following the close of the Bookbuild.

By participating in the Placing, each Placee (and any person acting on such Placee's behalf) agrees to indemnify and hold the Company, the Joint Bookrunners and each of their respective Affiliates, agents, directors, officers and employees harmless from any and all costs, claims, liabilities and expenses (including legal fees and expenses) arising out of or in connection with any breach of the representations, warranties, acknowledgements, agreements and undertakings given by the Placee (and any person acting on such Placee's behalf) in this Appendix or incurred by the Joint Bookrunners, the Company or each of their respective Affiliates, agents, directors, officers or employees arising from the performance of the Placee's obligations as set out in this Announcement, and further agrees that the provisions of this Appendix shall survive after the completion of the Placing.

The agreement to allot and issue Placing Shares to Placees (or the persons for whom Placees are contracting as agent) free of stamp duty and stamp duty reserve tax in the United Kingdom relates only to their allotment and issue to Placees, or such persons as they nominate as their agents, direct by the Company. Such agreement assumes that the Placing Shares are not being acquired 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 related to any other dealings in the Placing Shares, stamp duty or stamp duty reserve tax may be payable. In that event, the Placee agrees that it shall be responsible for such stamp duty or stamp duty reserve tax and neither the Company nor the Joint Bookrunners shall be responsible for such stamp duty or stamp duty reserve tax. If this is the case, each Placee should seek its own advice and they should notify the Joint Bookrunners accordingly. In addition, Placees should note that they will be liable for any capital duty, 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 United Kingdom by them or any other person on the acquisition by them of any Placing Shares or the agreement by them to acquire any Placing Shares and each Placee, or the Placee's nominee, in respect 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 non-United Kingdom stamp, registration, documentary, transfer or similar taxes or duties undertakes to pay such taxes and duties, including any interest and penalties (if applicable), 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 and/or the Joint Bookrunners have incurred any such liability to such taxes or duties.

The Joint Bookrunners and the Company will not be responsible for any liability to stamp duty or stamp duty reserve tax resulting from a failure to observe this requirement. Each Placee and any person acting on behalf of such Placee agrees to acquire Placing Shares pursuant to the Placing and agrees to indemnify the Company and the Joint Bookrunners in respect of the same on the basis that the Placing Shares will be allotted to a CREST stock account of a Joint Bookrunner or transferred to a CREST stock account of a Joint Bookrunner who will hold them as nominee on behalf of the Placee until settlement in accordance with its standing settlement instructions with it.

The representations, warranties, acknowledgements, agreements, confirmations and undertakings contained in this Appendix are given to each Joint Bookrunner for itself and on behalf of the Company and are irrevocable.

Each Placee and any person acting on behalf of the Placee acknowledges that the Joint Bookrunners do not owe any fiduciary or other duties to any Placee in respect of any representations, warranties, undertakings, acknowledgements, agreements or indemnities in the Placing Agreement.

Each Placee and any person acting on behalf of the Placee acknowledges and agrees that each Joint Bookrunner may (at its absolute discretion) satisfy its obligations to procure Placees by itself agreeing to become a Placee in respect of some or all of the Placing Shares or by nominating any connected or associated person to do so.

When a Placee or any person acting on behalf of the Placee is dealing with the Joint Bookrunners, any money held in an account with the relevant 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 relevant rules and regulations of the FCA made under the FSMA. Each 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 Joint Bookrunner's money in accordance with the client money rules and will be held by it under a banking relationship and not as trustee.
