Background to the Company

Sintana holds a diversified portfolio of direct and indirect interests in high-impact assets with significant hydrocarbon resource potential in emerging "frontier" geographies. Sintana offers investors a unique, capital-efficient vehicle to gain exposure to high-potential blocks in Namibia, Uruguay, and Angola. The Company's business model is built on securing interests in major-operated assets where drilling and development costs are predominantly carried by industry-leading partners, with current partners including TotalEnergies, Chevron, and Galp Energia.

With a multi-well catalyst work programme throughout 2026-2027 and with significant carried exposure providing material upside with minimised cost exposure, Sintana is positioned for a potential step-change in valuation driven by exploration successes across three distinct regions.

The portfolio is anchored by an interest in the world-class Mopane complex on PEL 83 in Namibia's Orange Basin, an asset on track for final investment decision in 2028, with the value of Sintana's Mopane interest alone supporting the Company's current market capitalisation.

The Board believes that the Sintana portfolio provides diversified exposure to high-impact exploration, appraisal and development with asymmetric upside exposure:

1. Diversified portfolio with multiple upside opportunities, underpinned by Mopane

Sintana's portfolio comprises diversified exposure across ten direct, indirect and potential acquisition assets. This provides a large number of options for potential value creation, offering a highly diversified portfolio of exploration and appraisal assets in some of the most prospective basins globally. Importantly, Sintana's portfolio is underpinned by its 4.9% indirect interest in the Mopane complex discoveries on PEL 83, with the Company fully carried until first oil, three wells expected to be drilled between 2026 and 2027, and a final investment decision target indicated by TotalEnergies for 2028.

2. Exposure to near-term high value activity

Sintana's core portfolio in Namibia, Uruguay and Angola is located in key global exploration "hot spots", offering exposure to some of the most prospective acreage for new oil and gas discoveries globally. With a diversified portfolio across multiple assets and opportunities, the Sintana portfolio will see multiple catalysts in the coming 24 months including multi-well drilling programmes, seismic studies, potential farm-outs and acquisition opportunities.

3. Established partnerships with Tier-1 operators

Sintana has a proven track-record of partnering with leading industry participants on its licences. Today, Sintana partners with Chevron, TotalEnergies, Galp Energia, Qatar Energy, Pancontinental and NAMCOR in Namibia, Chevron on the AREA OFF-1 block in Uruguay and Corcel in Angola (subject to completion of the transaction to acquire an interest in the KON-16 block). These partnerships provide Tier-1 operating teams with significant resources and industry-leading capabilities, de-risking project execution.

4. Reduced capital exposure through carries

Sintana's strategy is to create and maintain a portfolio of interests with minimised capital exposure, protected downside, and asymmetric upside exposure. The Company's assets benefit from significant carried interest arrangements with full or partial carried interest positions in relation to four of its five offshore licence interests in Namibia and in AREA OFF-1 in Uruguay. In particular, Sintana's indirect exposure to the world-class Mopane complex via its interest in PEL 83 benefits from a full carry through to first oil, underpinning the Company's base value whilst offering significant upside potential on both PEL 83 and across the wider portfolio.

5. Potential realisation opportunities

Sintana's portfolio provides exposure to highly prospective exploration prospects and, in the case of Mopane, discoveries of significant scale. The resulting ability to potentially realise multiple value uplifts from prospect to discovery via monetisation (including sale or divestment of key assets) significantly enhances the opportunities for shareholder returns.

Sintana's portfolio comprises the following interests:

1. TotalEnergies is operator elect, subject to completion of Galp Energia's announced farm-out of a 40% interest and operatorship to TotalEnergies - transaction subject to regulatory approvals in Namibia.

2. Letter of intent has been entered into for exclusivity on the potential indirect investment in PEL 37, with the transaction pending due diligence, and formal documentation, formal entry into the transaction is expected in H1 2026 with completion expected to follow thereafter in H22026.

3. Heads of terms entered into for the acquisition of the interest in KON-16 in Angola, with the transaction pending formal documentation and completion, which is expected in H2 2026.

Note: the core portfolio set out above does not include legacy assets in Colombia (currently in the process of being monetized) and The Bahamas (both of which offer potential for value / monetisation)

1. PEL 83 (Mopane Discoveries)

   Sintana holds a 4.9% indirect interest in PEL 83, which is operated by TotalEnergies (operator-elect). This flagship asset sits in the heart of the Orange Basin and is home to the world-class Mopane discoveries, where five successful wells have already confirmed a 1.4 billion boe (3C) resource. The asset provides a robust valuation floor for the Company, with the first phase of Mopane alone carrying an indicative value of US$195¹ - US$242 million², effectively underpinning Sintana's entire market capitalisation. Sintana benefits from a full financial carry through the Final Investment Decision ("FID") and until first production, shielding the Company from development capital expenditures. Near-term catalysts include three well appraisal program in 2026/27 to define the full scale of the complex ahead of a targeted FID in 2028.

2. PEL 90

   In PEL 90, to the west of PEL 83, Sintana maintains a 4.9% indirect interest. PEL 90 is operated by Chevron. This high-impact exploration block offers exposure to basin-floor fans which are believed to be analogous to the multi-billion-barrel Venus discovery to the south. Chevron is currently maturing targets for the Nabba-1 deepwater exploration well, planned for late 2026 or early 2027. This well represents a significant valuation catalyst, with an indicative success-case value to Sintana of approximately US$161 million³. The Company's current financial exposure is limited to an estimated investment of US$6 - US$9 million, offering investors highly asymmetric upside potential.

3. PEL 82

   Sintana holds a 4.9% indirect interest in PEL 82, which is located in the Walvis Basin and operated by Chevron. Recognised as one of the most technically advanced opportunities in Namibia outside of the Orange Basin, PEL 82 features an active petroleum system confirmed by previous drilling. Chevron is evaluating drilling a potentially basin-opening exploration well - Gemsbok-1 - in 2027, which is expected would target resources with Mopane-scale potential. Sintana is fully carried on the drilling of this well, offering an indicative success-case value of US$149 million⁴ net to the Company for nil investment.

4. PEL 87

   Sintana retains a 7.35% indirect interest in PEL 87, which is operated by Pancontinental. PEL 87 contains the Saturn turbidite complex that spans approximately2,400 square km and has significant oil potential. Sintana's interest is carried through final investment decision, providing Sintana with significant upside potential but limited near-term capital need. The operator is currently conducting a farm-out process seeking to bring in an additional partner, minimise cost exposure and accelerate the drilling of this high-potential asset.

5. PEL 79

   Sintana holds a 16.17% indirect interest in PEL 79, where the national oil company NAMCOR is the operator. This asset further diversifies Sintana's exposure within the Orange Basin, providing additional scale in a region that has become the global focal point for offshore exploration.

6. PEL 103

   Sintana holds a 13.23% indirect interest in PEL 103, located onshore North-East Namibia in the Waterberg Basin. Thick Permian Karoo Supergroup sediments are present in the Waterberg Basin, which provide a favourable setting for hydrocarbon exploration. Only a small portion of the basin has been drilled to date and more untested sub-basins are likely to exist.

7. PEL 37 (Potential Asset Interest)

   Sintana announced on 21 January 2026, that it had entered into a Letter of Intent providing for a period of exclusivity in relation to a potential investment to secure an indirect 30% interest in PEL 37 in the Walvis Basin, offshore Namibia. PEL 37 is adjacent to the Chevron-operated PEL 82 licence, which is expected to see a basin-opening well drilled in 2027. Any success on PEL 82 would significantly increase the potential value of PEL 37 and is expected to positively position future farm-out discussions on PEL 37. The Letter of Intent contemplates an acquisition of a 30% interest from current operator Paragon Oil & Gas for total consideration of US$6 million, to be paid in a combination of cash and shares. The transaction is pending finalisation of due diligence and formal documentation; formal entry into the transaction is expected in H1 2026 with completion expected to follow thereafter in H2 2026.

1. AREA OFF-1

   Sintana holds a 40% direct interest in AREA OFF-1, operated by Chevron. This block is offshore Uruguay and contains two primary prospects, Teru Teru and Anapero, with a combined Pmean prospective resource of approximately 1.3 billion barrels and upside potential of 2.8 billion barrels (P10 case). Sintana is fully carried through the current 3D seismic acquisition campaign being acquired by Chevron and benefits from a 50% carry on the first exploration well. The indicative success-case value for Sintana's interest in AREA OFF-1 is estimated at US$271 million⁵, assuming a future farm-down to a 10% interest in exchange for a full carry to first oil.

2. AREA OFF-3

   Sintana maintains a 100% direct interest and acts as the operator for AREA OFF-3. This block features two primary prospects, Benteveo and Amalia, with a Pmean prospective resource of 418 million barrels and significant upside potential (955 MMbbls upside (P10) case). The Company is currently running an active farm-out process with a view to securing a major partner to progress exploration and appraisal activities on the licence. Value is expected to be unlocked in the near term through partner selection and read-across from drilling activities on the OFF-6 licence by APA, which is expected for 2027. It is noted that Qatar Energy and Chevron recently farmed into adjacent acreage on both sides of AREA OFF-3.

1. KON-16

   Sintana is in the process of completing the acquisition of a 5% indirect interest in the KON-16 block, which is operated by Corcel. Located in the onshore Kwanza Basin, this asset offers offshore-scale upside potential in pre and post-salt reservoirs - estimated at up to 400 million barrels - but with the significantly lower cost structure typical of an onshore development. Corcel has recently completed a 2D seismic acquisition campaign and is expected will undertake a farm in process in late 2026, with a view to securing a partner for an initial exploration well in 2027. Sintana's interest in KON-16 provides a low-cost catalyst with an indicative success-case value of US$76 million (net to Sintana). Completion of this transaction is expected in the second half of 2026, further diversifying the Company's high-impact African portfolio.

Unless otherwise stated, defined terms used in this Appendix I are set out in Appendix II.

1. Details of the Placing Agreement and the Placing Shares

   Stifel are acting as sole bookrunner, and Zeus are acting as joint broker and co-lead manager, in connection with the Placing. Cavendish Capital Markets Limited ("Cavendish") is acting as joint broker and co-lead manager in connection with the Placing pursuant to the terms of a separate engagement between the Company and Cavendish. Cavendish is not a party to the Placing Agreement and has no obligations or liabilities thereunder.

   The Banks have entered into the Placing Agreement with the Company under which, on the terms and subject to the conditions set out in the Placing Agreement, the Banks, as agents for and on behalf of the Company, have agreed to use their respective reasonable endeavours to procure placees for the Placing Shares. The Placing is not being underwritten by the Banks or any other person.

   The price per Placing Share at which the Placing Shares are to be placed is CA$0.41 (the "Issue Price") (approximately 22.5 pence per share). The timing of the closing of the book and allocations are at the discretion of the Company and the Banks. Details of the total number of Placing Shares will be announced by the Company in the announcement of the results of the Placing (the "Placing Results Announcement"). While the Company has set out an expected amount to be raised pursuant to the Fundraising, in the event that the demand exceeds this such that the Company could raise an amount in excess of the stated amount, the Company shall have the discretion, with the prior agreement of the Banks, to increase the number of Placing Shares to be issued pursuant to the Fundraising, subject to the receipt of all applicable regulatory approvals.

   The Placing Shares will be allotted and issued utilising the Company's existing share issuance authorities.

   The Placing Shares have been, or will be duly authorised and will, when issued by the Company, subject to receipt by the Company in full of the consideration for such Placing Shares, be credited as fully paid and non-assessable and will be issued subject to the articles and by-laws of the Company and rank pari passu in all respects with the Existing Common Shares, including the right to receive all dividends and other distributions declared, made or paid on or in respect of the 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 other than applicable restrictions on transfer or resale imposed by applicable securities laws, including the TSXV Rules and the AIM Rules.

2. Application for listing and admission to trading

   Applications will be made to the TSX-V and the London Stock Exchange for admission of the New Common Shares to trading on the TSX-V and AIM. It is expected that AIM Admission will occur at 8.00 a.m. (BST) on 27 May 2026 (or such later time or date as the Banks may agree with the Company, being no later than 8.00 a.m. (BST) on the Long Stop Date) and that dealings in the Enlarged Share Capital will commence at that time.

3. Participation in, and principal terms of, the Placing

   The Banks are arranging the Placing as agents of the Company.

   Participation in the Placing will only be available to persons who may lawfully be, and are, invited to participate by any of the Banks without requiring the filing of a prospectus or registration statement or delivering an offering memorandum or similar disclosure document under all applicable securities laws. Each of the Banks may itself agree to be a Placee in respect of all or some of the Placing Shares or may nominate any member of its group to do so.

   The Bookbuild will establish the aggregate amount payable to the Banks, as settlement agents for the Company, by all Placees whose orders are accepted. The number of Placing Shares will be agreed by the Banks (in consultation with the Company) following completion of the Bookbuild. The number of Placing Shares to be issued (in aggregate) will be announced on a Regulatory Information Service following the completion of the Bookbuild in the Placing Results Announcement. While the Company has set out an expected amount to be raised pursuant to the Fundraising, in the event that the demand exceeds this such that the Company could raise an amount in excess of the stated amount, the Company shall have the discretion, with the prior agreement of the Banks, to increase the number of Placing Shares to be issued pursuant to the Fundraising, subject to the receipt of all applicable regulatory approvals.

   Prospective Placees are required to communicate their order orally by telephone or in writing to the relevant Banks. Each order should state the number of Placing Shares up to which the prospective Placee wishes to subscribe for at the Issue Price. A request to participate in the Bookbuild is made on the terms and subject to the conditions in this Appendix I and shall constitute a legally binding offer from the Placee on behalf of which it is made. Such offer will not be capable of variation or revocation after the time at which it is submitted, except with the relevant Bank's consent. The Banks reserve the right not to accept orders or to accept orders in part rather than in whole without further consultation with the prospective Placees. The acceptance of the orders shall be at the Banks' absolute discretion, subject to agreement with the Company.

   The Bookbuild is expected to close no later than 6.00 a.m. (BST) on 18 May 2026 but may be closed earlier or later at the discretion of the Banks (after consultation with the Company). The Banks may, in agreement with the Company, accept orders that are received after the Bookbuild has closed. The Company reserves the right (upon the prior agreement of the Banks) to reduce or increase the number of Shares to be issued pursuant to the Placing, in its absolute discretion, subject to the receipt of all applicable regulatory approvals.

   Allocations of the Placing Shares will be determined by the Banks after consultation with the Company (and in accordance with the relevant Bank's allocation policy as has been supplied by each Bank to the Company in advance of such consultation). Allocations will be confirmed orally by the relevant Banks to the Placee, and a Form of Confirmation will be despatched as soon as possible thereafter. The Bank's oral confirmation to such Placee shall trigger the immediate, separate, irrevocable and binding obligation for such person (who will at that point become a Placee) to subscribe for the number of Placing Shares allocated to it and to pay or procure payment in cleared funds an amount equal to the Issue Price in respect of each Placing Share that such Placee has agreed to acquire on the terms and conditions set out in this Appendix I and in accordance with the Company's articles and by-laws.

   Each Placee's allocation and commitment will be evidenced by a Form of Confirmation issued to such Placee. The terms of this Appendix I will be deemed incorporated in that Form of Confirmation.

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

   All obligations under the Bookbuild and the Placing will be subject to fulfilment or (where applicable) waiver 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 "Right to terminate under the Placing Agreement" prior to Admission.

   By participating in the Placing, each Placee agrees 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.

   To the fullest extent permissible by law, none of the Banks, the Company nor any of their respective affiliates, agents, directors, officers, representatives or employees 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 the Banks, the Company, nor any of their respective affiliates, agents, directors, officer's representatives or employees shall have any responsibility or liability (including to the extent permissible by law, any fiduciary duties) in respect of each Bank's conduct of the Placing.

   The Placing Shares will be issued subject to the terms and conditions of this Announcement 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 or the Bank's conduct of the Placing.

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

   Each potential Placee: (i) who is located or resident in Canada, is an eligible purchaser satisfying the requirements of an available exemption under either NI 45-106 or OSC Rule 72-503; (iii) who is located or resident in Australia, must be a "sophisticated investor" within the meaning of section 708(8) of the Corporations Act, or a "professional investor" within the meaning of section 708(11) of the Corporations Act, or a person to whom an offer of securities under Chapter 6D of the Corporations Act does not apply; or (iv) who is located in the United States must qualify as a QIB and allocation of Placing Shares to it shall be conditional on its delivery of a US investor representation letter in the form provided to it.

4. Conditions of the Placing

   The Placing and Admission is conditional upon the Placing Agreement becoming unconditional and not having been terminated in accordance with its terms. The obligations of the Banks under the Placing Agreement in respect of the Placing Shares are conditional on customary conditions, including (amongst others):

   1. the Company having complied with its obligations which fall to be performed on or prior to Admission under the Placing Agreement;

   2. the Subscription Agreements having been duly executed by the parties thereto and having become unconditional in all respects, save for any conditions relating to Admission having occurred, and not having lapsed or been breached, varied or terminated;

   3. the Company allotting the Placing Shares and the Subscription Shares, subject only to Admission;

   4. receipt of TSXV Conditional Approval in respect of the Placing Shares and the Subscription Shares prior to Admission;

   5. none of the Banks having terminated the Placing Agreement; and

   6. Admission occurring no later than 8.00 a.m. (BST) on 27 May 2026 (or such later time or date as the Banks may otherwise agree with the Company, being no later than 8.00 a.m. (BST) on the Long Stop Date),

   
   (the "Conditions").

   The Banks may, jointly, at their discretion and upon such terms as they think fit, waive compliance by the Company with the whole or any part of any of their obligations in relation to the Conditions or extend the time or date provided for fulfilment of any such Conditions in respect of all or any part of the performance thereof, save in respect of any condition relating to the allotment of the Placing Shares and the Subscription Shares, Admission, or TSXV Conditional Approval. Any such extension or waiver will not affect Placees' commitments as set out in this Appendix I.

   If: (i) any of the Conditions are not fulfilled or (where permitted) waived by the Banks by the relevant time or date specified (or such later time or date as the Banks may agree with the Company, being no later than the Long Stop Date); or (ii) the Placing Agreement is terminated in the circumstances specified below under "Right to terminate under the Placing Agreement" prior to Admission, the Placing will not proceed and the Placees' rights and obligations hereunder in relation to the Placing Shares shall cease and terminate at such time and each Placee agrees that no claim can be made by it or on its behalf (or any person on whose behalf the Placee is acting) in respect thereof.

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

5. Right to terminate under the Placing Agreement

   Any of the Banks is entitled, at any time before Admission, to terminate the Placing Agreement in accordance with its terms in certain circumstances, including (amongst other things):

   1. if any of the Conditions which has not been waived (if capable of waiver), is not satisfied or becomes incapable, for any reason, of being satisfied or in the good faith opinion of the Banks is unlikely to be satisfied before Admission;

   2. where the Company has, in the opinion of the Banks in their absolute discretion, failed to comply in any material respect with any of its obligations under the Placing Agreement or a breach of the Placing Agreement shall have occurred;

   3. where, in the opinion of the Banks in their absolute discretion, any of the Warranties are not, or has ceased to be, true and accurate in any material respect;

   4. where, it has come to the notice of any of the Banks that any statement contained in the Placing Documents has become untrue, incorrect or misleading in any respect or that statements have been omitted from the Placing Documents which, in any such case, in the opinion of the Banks in their absolute discretion, is material;

   5. where London Stock Exchange or TSX-V announces that any securities of the Company will be delisted or suspended from quotation by AIM, TSX-V or any other order, action or proceeding which ceases trades or otherwise operates to prevent or restrict the trading of the Shares or any other securities of the Company is made or threatened by a securities regulatory authority (other than a temporary halt of stock in connection with the bookbuild);

   6. where a matter has arisen which has or might reasonably be expected to give rise to a claim under any of the indemnities set out in the Placing Agreement;

   7. where there shall have occurred or come into effect any event or omission which in the opinion of the Banks in their absolute discretion is materially adverse in the context of Admission;

   8. where a Subscription Agreement has been terminated or is otherwise no longer in full force and effect; and/or

   9. where there has occurred or is reasonably likely to occur any adverse change which, in the opinion of the Banks, would be materially adverse to the success of Admission or would render proceeding with Admission impracticable or inadvisable.

   
   Upon termination, the parties to the Placing Agreement shall be released and discharged (except for any liability arising before or in relation to such termination) from their respective obligations under or pursuant to the Placing Agreement, subject to certain exceptions.
   
   By participating in the Placing, each Placee agrees with the Company and the Banks that: (i) the exercise by the Banks of any right of termination or of any other discretion under the Placing Agreement shall be within the absolute discretion of the Banks and that they need not make any reference to, or consult with, Placees and that they (nor any of them) shall have no liability to Placees whatsoever in connection with any such exercise or failure to so exercise; and (ii) its rights and obligations terminate only in the circumstances described above under "Right to terminate under the Placing Agreement" and "Conditions of the Placing", and its participation will not be capable of rescission or termination by it after oral confirmation by the Banks of the allocation and commitments following the close of the Bookbuild.

6. Registration and Settlement
   
   Settlement of transactions in the Placing Shares (ISIN: CA82938H1073) following Admission will take place within the system administered by Euroclear UK & International Limited ("CREST"), using the delivery versus payment mechanism, subject to certain exceptions. The Banks reserve the right to require settlement for, and delivery of, the Placing Shares (or any part thereof) to Placees by such other means that they may deem necessary if delivery or settlement is not possible or practicable within the CREST system or would not be consistent with the regulatory requirements in the Placee's jurisdiction.
   
   In order to enable Placees in the United Kingdom to settle their securities through CREST, the Company has appointed Computershare Investor Services plc to act as a depositary (the "Depositary") to hold the Shares and issue dematerialised depositary interests representing the underlying Shares ("Depositary Interests"). The Depositary will hold the Shares on trust for the relevant shareholders.
   
   The Depositary Interests are independent English securities and held on a register maintained by the Depositary. The Depositary Interests have the same security code and ISIN number as the underlying Shares which they represent and do not require a separate admission to AIM. Any references to Placing Shares in this Announcement shall include any Depositary Interests issued in relation to the same.
   
   The Banks are acting as settlement banks. Following the close of the Bookbuild, each Placee to be allocated Placing Shares in the Placing will be sent a Form of Confirmation stating the number of Placing Shares allocated to them at the Issue Price, the aggregate amount owed by such Placee to a Bank and settlement instructions. Each Placee agrees that it will do all things necessary to ensure that delivery and payment is completed in accordance with the standing CREST or certificated settlement instructions in respect of the Placing Shares that it has in place with a Bank.
   
   The Company will deliver (or will procure the delivery of) the Placing Shares to CREST accounts operated by the Banks as agents for the Company and the Banks will each enter its respective delivery instruction into the CREST system. The input to CREST by a Placee of a matching or acceptance instruction will then allow delivery of the relevant Placing Shares to that Placee against payment. It is expected that settlement in respect of the Placing Shares will take place at 8.00 a.m. (BST) on or about 27 May 2026.
   
   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 Sterling Overnight Index Average (SONIA) as determined by the Banks.
   
   Each Placee is deemed to agree that, if it does not comply with these obligations, the Banks may sell any or all of the Placing Shares allocated to that Placee on such Placee's behalf and retain from the proceeds, from the Bank'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 will be required to bear any stamp duty or stamp duty reserve tax or other taxes or duties (together with any interest or penalties) imposed in any jurisdiction which may arise upon the sale of such Placing Shares on such Placee's behalf.
   
   If Placing Shares are to be delivered to a custodian or settlement agent, Placees should ensure that the Form of Confirmation is copied and delivered immediately to the relevant person within that organisation. Insofar as Placing Shares are issued in a Placee's name or that of its nominee or in the name of any person for whom a Placee is contracting as agent or that of a nominee for such person, such Placing Shares should, subject as provided below, be so registered free from any liability to UK stamp duty or stamp duty reserve tax. If there are any circumstances in which any stamp duty or stamp duty reserve tax or other similar taxes or duties (including any interest and penalties relating thereto) is payable in respect of the allocation, allotment, issue, sale, 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 the Banks or the Company shall be responsible for payment thereof.

7. No Prospectus

9. Taxation

   The agreement to allot and issue certain of the Placing Shares by the Company to Placees (and/or to persons for whom such Placee is contracting as agent) free of stamp duty and stamp duty reserve tax relates only to their allotment and issue to Placees, or such persons as they nominate as their agents, direct from the Company for the Placing Shares in question.

   There should be no liability to UK stamp duty or SDRT arising on the allotment of the Placing Shares by the Company. The registration of and the issue of definitive share certificates to Shareholders should not give rise to any liability to stamp duty or SDRT.

   In addition, neither UK stamp duty nor SDRT should arise on the transfers/sale of Shares on AIM (including instruments transferring Shares and agreements to transfer Shares).

   Such agreement also 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 are any such arrangements, or the settlement relates to any other dealing in the Placing Shares, stamp duty or stamp duty reserve tax or other similar taxes or duties may be payable, for which neither the Company nor the Banks will be responsible and the Placees shall indemnify the Company and the Banks on an after-tax basis for any stamp duty or stamp duty reserve tax or other similar taxes or duties (together with interest, fines and penalties) in any jurisdiction paid by the Company or the Banks in respect of any such arrangements or dealings. If this is the case, each Placee should seek its own advice and notify the Banks s accordingly. Placees are advised to consult with their own advisers regarding the tax aspects of the subscription for Placing Shares.

   The Company and the Banks are not liable to bear any taxes that arise on a sale of Placing Shares subsequent to their acquisition by Placees, including any taxes arising otherwise than under the laws of any country in the EEA. Each prospective Placee should, therefore, take its own advice as to whether any such tax liability arises and notify their Bank and the Company accordingly. Furthermore, each Placee agrees to indemnify on an after-tax basis and hold the Bank and/or the Company and their respective affiliates harmless from any and all interest, fines or penalties in relation to stamp duty, stamp duty reserve tax and all other similar duties or taxes in any jurisdiction to the extent that such interest, fines or penalties arise from the unreasonable default or delay of that Placee or its agent.

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

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

   The Placing Shares to be issued pursuant to the Placing will not be admitted to trading on any stock exchange other than AIM, and the TSX-V.
