Proposed Placing, Subscription and Open Offer

Scancell Holdings plc (AIM: SCLP), the developer of novel immunotherapies for the treatment of cancer, is pleased to announce a proposed issue of new Ordinary Shares in the Company by way of the Placing and Subscription to raise a minimum of GBP6.0 million, before expenses, at an issue price of 12 pence per share.

In addition, in order to provide Qualifying Shareholders with an opportunity to participate in the fundraise at the Issue Price, subject to the successful closing of the Placing and Subscription, the Company proposes to make an Open Offer to all Qualifying Shareholders to raise additional gross proceeds of up to GBP2.0 million for the Company. The proposed Placing, Subscription and Open Offer is within the Company's existing allotment authorities granted at its prior annual general meeting.

The net proceeds from the Capital Raise, in addition to the Company's existing cash resources and anticipated tax credits, will be used to:

-- Commence the SCIB1-checkpoint inhibitor Phase 2 US combination study in late stage melanoma, planned to start in Q4 2018 (subject to FDA approval) utilising the Ichor TriGrid v2.0 electroporation device;

-- Support the Cancer Research UK ("CRUK") development of SCIB2 for non-small-cell lung cancer ("NSCLC");

-- Commence the First-In-Human study with Modi-1 in patients with triple-negative breast cancer ("TNBC"), ovarian cancer and sarcoma planned to start in H1 2019;

   --     Identify Modi-specific T cell receptors in collaboration with BioNTech; and 

-- Initiate pre-clinical Modi-2 development programme for oesophageal, gastric, pancreatic and colorectal cancers.

Dr Cliff Holloway, Chief Executive Officer of Scancell, commented:

"With this proposed funding we can build on the strong Phase 1/2 data for our lead ImmunoBody(R) product, SCIB1, and commence the next phase of clinical development in combination with a checkpoint inhibitor in melanoma. This funding will also enable the first candidate from our Moditope(R) platform, Modi-1, to enter the clinic in several cancer indications with high unmet need, including triple-negative breast cancer, ovarian cancer and sarcoma."

The proposed Placing and Subscription of new Ordinary Shares in the Company will be with existing and new investors, and the Executive Chairman of the Company, Dr John Chiplin, intends to invest approximately GBP100,000 in the Placing.

The Placing will be conducted by way of a Bookbuild which will be launched immediately following this Announcement in accordance with the Terms and Conditions set out in Appendix II. The Placing Shares are not being made available to the public. It is envisaged that the Bookbuild will be closed no later than 4.30 p.m. (London time) today, 18 April 2018. Details of the number of Placing Shares, Subscription Shares and the approximate gross proceeds of the Placing and Subscription will be announced as soon as practicable after the closing of the Bookbuild. The Placing and Subscription are not underwritten.

Panmure Gordon is acting as Financial Adviser, Nominated Adviser and sole Bookrunner to the Company and no one else in relation to the Placing. Accordingly, it will not be responsible to any person other than the Company for providing the regulatory and legal protections afforded to its clients nor for providing advice in relation to the contents of this Announcement or any matter, transaction or arrangement referred to in it.

APPIX I

PROPOSED CAPITAL RAISE

Background to the Capital Raise

Scancell is developing novel immunotherapies for the treatment of cancer based on its technology platforms, ImmunoBody(R) and Moditope(R), with four products in multiple cancer indications.

ImmunoBody(R) platform

Scancell's ImmunoBody(R) vaccines target dendritic cells and stimulate both parts of the cellular immune system: the helper cell system where inflammation is stimulated at the tumour site and the cytotoxic T-lymphocyte (CTL) response where immune system cells are primed to recognise and kill specific cells. Each ImmunoBody(R) vaccine can be designed to target a particular cancer in a highly specific manner.

Scancell's first ImmunoBody(R) and lead programme, SCIB1, is being developed for the treatment of melanoma. Data from the Phase 1/2 clinical trial demonstrate that SCIB1, when used as monotherapy, has a marked effect on tumour load, produces a melanoma-specific immune response and highly encouraging survival trend without serious side effects. In patients with resected disease there is increasing evidence to suggest that SCIB1 may delay or prevent disease recurrence.

The Company's second ImmunoBody(R) vaccine, SCIB2, has been designed to induce high avidity T cell responses in the majority of patients that over-express the cancer antigen NY-ESO-1, including those with lung and other epithelial cancers.

Pre-clinical data on a combination of SCIB1 or SCIB2 and checkpoint inhibition (blockade of the PD-1 or CTLA-4 immune checkpoint pathways) have shown enhanced tumour destruction and significantly longer survival times than when either treatment was used alone. Experimental data suggests that the high avidity T cells induced by ImmunoBody(R) vaccines increase expression of PDL-1 on the tumour cell surface, thereby making the tumours more sensitive to checkpoint inhibitor drugs.

These data suggest that SCIB1 has the potential to become both a stand-alone adjuvant treatment for early stage metastatic melanoma and an attractive partner with checkpoint inhibitors for later stage disease. Survival data from the Phase 1/2 trial in patients with Stage III/IV malignant melanoma continues to deliver increasingly impressive results, with 14 of 16 resected patients receiving 2-4 mg doses of SCIB1 having survived for more than five years. Data from the Phase 1/2 trial, combined with the animal data showing the potential value of a SCIB1/checkpoint inhibitor combination, has given the Directors confidence to proceed with a US FDA IND submission for a SCIB1 plus checkpoint inhibitor Phase 2 trial, which is expected to be filed in Q2 2018.

The US clinical study will assess the impact of adding SCIB1 to the checkpoint inhibitor Keytruda in patients with late stage melanoma. The aim will be to improve the objective response rates of anti-PD-1 monotherapy without adding additional toxicity. The trial will include up to 25 patients in total and is targeting a response rate of 55% compared to a response rate to Keytruda alone of approximately 30% and objective tumour responses in 12 or more patients. The Company intends to commence enrolment of Stage III/IV metastatic melanoma patients to the study in Q4 2018, led by principal investigator Dr Keith Flaherty. Following which, the Phase 2 trial will be completed in two parts. The Directors believe that the first part of the Phase 2 trial will be completed in H1 2019 and the second part will be completed in H1 2020.

The Directors believe that the data generated by the Company to date with the SCIB2 ImmunoBody(R) suggest that it should be well tolerated and be an ideal complement to existing and emerging portfolios of checkpoint inhibitor therapies in the treatment of NSCLC. Currently, checkpoint inhibitors are proving less effective in lung cancer, with 80% of patients still requiring a better standard of care. In December 2017, the Company announced a collaboration with CRUK whereby CRUK have agreed to fund and sponsor a UK-based Phase 1/2 clinical trial of SCIB2 in combination with a checkpoint inhibitor in patients with solid tumours, focusing on NSCLC in the first instance. CRUK's Centre for Drug Development (CDD) will be responsible for manufacturing the clinical trial supplies of SCIB2, conducting pre-clinical testing, sponsoring and managing the clinical trial, including the clinical trial timelines. The manufacturing development for SCIB2 is expected to start in Q2 2018 ahead of expected commencement of a toxicology study in Q4 2018 and completion of the study in H1 2019. Scancell will have the option to licence the rights to the data on completion of the study, subject to paying a licence fee. If Scancell elects not to exercise the option, CRUK will retain the right to take the SCIB2 programme forward in all indications and there will be a revenue share agreement between the parties. In addition, the Company has partnered with the Addario Foundation, one of the largest and most highly regarded US patient advocacy groups, to accelerate the development of SCIB2.

Moditope(R) platform

Scancell's Moditope(R) immunotherapy platform is based on exploiting the normal immune response to stressed cells, which is largely mediated by CD4 T cells, and harnessing this mechanism to eradicate tumours. Moditope(R) is a peptide-based vaccine platform that stimulates the production of killer CD4 T cells that induce anti-tumour activity without toxicity. Although CD8 T cell responses to tumour--associated antigens have been reported, it is difficult to induce tumour-specific CD4 T cell responses due to self--tolerance against normal CD4 T cell epitopes. The ability of Moditope(R) citrullinated peptides to induce CD4 cytotoxic T cells against tumour-associated epitopes has therefore, in the Directors' opinion, added a new dimension to the potential of anti--tumour vaccines, and the Directors believe that the Moditope(R) platform offers a new approach to immuno-oncology that could play a major role in the development of safe and effective cancer immunotherapies in the future.

The value of the Moditope(R) platform received a significant boost following notification from the European Patent Office that the examiner had indicated that most of the patent claims for the use of citrullinated peptides for the treatment of cancer will be allowable. In February 2018, the European Patent Office announced its intention to grant a European patent for the Moditope(R) immunotherapy platform.

Continued progress has been made with the Moditope(R) platform, and the Company has identified and validated multiple targets, including enolase, which, together with vimentin, will form the basis for Modi-1, Scancell's first product derived from the Moditope(R) platform. Pre-clinical data suggests that Modi-1 should be effective in up to 90% of patients with TNBC, up to 95% of patients with ovarian cancer and up to 100% of patients with sarcoma.

Modi-1 is now being progressed to a Phase 1/2 clinical trial for the treatment of sarcomas, TNBC and ovarian cancer, with the Company having selected an optimised adjuvant (AMPLIVANT(R)) to combine with Modi-1 which reduces the dose required to induce responses in animals by up to 100-fold. The Company will shortly be commencing the manufacture of the AMPLIVANT(R) -Modi-1 conjugate therapy vaccine having recently entered into a GMP manufacturing agreement with The PolyPeptide Group. The Company will file the Clinical Trial Authorisation and commence the clinical trial for Modi-1 in H1 2019, with the first efficacy and safety data expected in H2 2019.

Modi-2 targets multiple solid tumours (including oesophageal, gastric, colorectal, breast (non-TNBC), cervical, prostate, liver, renal, endometrial, bladder and thyroid tumours) and pre-clinical development of selected epitopes is planned during 2018. The Company expects to characterise its Modi-2 development candidate and begin GMP manufacturing in H2 2019. Both Modi-1 and Modi-2 will target tumours that are generally unresponsive to checkpoint inhibitor therapy. In addition, an international, multi-disciplinary team of leading cancer immunotherapy scientists in Europe and the US, led by Professor Lindy Durrant, Chief Scientific Officer of Scancell, and in partnership with Genentech, BioNTech and ISA Pharmaceuticals, has been shortlisted to the final stages of CRUK's Grand Challenge. Modi-3 forms a central element of the team's proposal with a focus on head and neck cancer, glioblastoma, lung, and pancreatic cancer, all of which currently have a poor prognosis.

The Company recently entered into a research collaboration with BioNTech for the potential development of innovative, T cell receptor based therapeutics for the treatment of cancer. This research collaboration combines the Moditope(R) immunotherapy platform and BioNTech's platform technology for high-throughput cloning and characterisation of naturally selected T cell receptors.

The Company is continuing discussions on potential commercial partnership discussions for the Moditope(R) platform alongside its clinical development plans, with multiple partnering discussions in progress.

Additional Technology Agreement

Today, the Company announced that it had entered into an agreement with the University of Nottingham to acquire a number of novel monoclonal antibodies to tumour-associated glycans alongside the acquisition of a proprietary technology to enable the modification of the constant region (FC) of a human antibody to allow direct tumour killing. The Directors believe that these acquisitions complement Scancell's existing cancer immunotherapy platforms, ImmunoBody(R) and Moditope(R) and will broaden the strength and potential of Scancell's immunotherapy pipeline.

Reasons for the Capital Raise and use of proceeds

The net proceeds of the Capital Raise will be used by the Company to commence Moditope(R) clinical development and to continue to support the ImmunoBody(R) pipeline. The Board believes this interim funding could add significant incremental value and support the Company's on-going commercial discussions with potential partners, in addition to generating short term news flow.

The net proceeds of the Capital Raise, in addition to the Company's existing cash resources and anticipated tax credits, will be used to:

-- Commence the SCIB1-checkpoint inhibitor Phase 2 US combination study in late stage melanoma, planned to start in Q4 2018 (subject to FDA approval) utilising the Ichor TriGrid v2.0 electroporation device;

   --     Support the CRUK development of SCIB2 for NSCLC; 

-- Commence the First-In-Human study with Modi-1 in patients with TNBC, ovarian cancer and sarcoma planned to start in H1 2019;

   --     Identify Modi-specific T cell receptors in collaboration with BioNTech; and 

-- Initiate pre-clinical Modi-2 development programme for oesophageal, gastric, pancreatic and colorectal cancers.

Therapeutic drug development is a long process and the Directors believe that the Company will require additional funding in order to complete the aforementioned SCIB1 clinical study and Modi-1 study. The timing of the aforementioned studies are also subject to, inter alia, timely regulatory approval.

Additional funding could be provided either by a commercial agreement with a development partner, such as a large pharmaceutical company, or by further equity issuance to existing and/or new Shareholders. The Directors believe that delivering the milestones outlined above will enhance the value of the Company and prepare it for further later stage fundraising. The Directors also believe that these milestones will ensure wider recognition of the Company both in the US and Europe for the quality and value of both the ImmunoBody(R) and Moditope(R) platforms.

Details of the Placing and Subscription

The Company proposes to raise a minimum of GBP6.0 million, before expenses, by the placing of at least 45,000,000 Placing Shares at the Issue Price to the Placees and through the subscription of 5,000,000 Subscription Shares at the Issue Price pursuant to the Subscription. The Placing Shares will, pursuant to the Placing and Open Offer Agreement which the Company has entered into with Panmure Gordon, be placed by Panmure Gordon, as agent for the Company, with existing and new institutional investors. The Company has conditionally agreed to issue 5,000,000 Subscription Shares at the Issue Price to certain professional investors pursuant to the Subscription.

The Placing and Open Offer Agreement contains warranties from the Company in favour of Panmure Gordon in relation to, inter alia, the Company and its business. In addition, the Company has agreed to indemnify Panmure Gordon in relation to certain liabilities it may incur in undertaking the Placing and Subscription. Panmure Gordon has the right to terminate the Placing and Open Offer Agreement in certain circumstances prior to the First Admission, in particular, it may terminate in the event that there has been a breach of any of the warranties or for force majeure. The Placing and Subscription will not be underwritten.

The Placing is conditional, inter alia, upon:

(i) the Placing and Open Offer Agreement becoming or being declared unconditional in all respects and not having been terminated in accordance with its terms prior to First Admission;

(ii) the Subscription Letters becoming unconditional in accordance with their terms (save for any condition relating to First Admission) and the subscription funds being received by the Company prior to First Admission; and

(iii) First Admission becoming effective by no later than 8.00.a.m. (London time) on 20 April 2018 or such later time and/or date (being no later than the Final Date) as Panmure Gordon and the Company may agree.

If any of the conditions are not satisfied, the Placing Shares will not be issued and all monies received from the Placees will be returned to them (at the Placees' risk and without interest).

The Subscription is conditional, inter alia, upon, First Admission and the Placing and Open Offer Agreement becoming wholly unconditional (save for any condition relating to First Admission) and not being terminated.

The Placing Shares and Subscription Shares are not subject to clawback and are not part of or subject to any condition related to the Open Offer.

The Placing Shares and the Subscription Shares (and the Open Offer Shares) will be issued free of all liens, charges and encumbrances and will, when issued and fully paid, 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 after the date of their issue.

Application has been made to the London Stock Exchange for the admission of the Placing Shares and Subscription Shares to trading on AIM. It is expected that First Admission will occur and that dealings will commence at 8.00 a.m. (London time) on 20 April 2018 at which time it is also expected that the Placing Shares will be enabled for settlement in CREST.

The Placing will be effected by way of the Bookbuild to be managed by Panmure Gordon and will be conducted in accordance with the terms and conditions set out in Appendix II. The Bookbuild will commence with immediate effect and the book is expected to close no later than 4.30 p.m. (London time) today, 18 April 2018, but Panmure Gordon reserves the right to close the book earlier or later, without further notice. The Company has received non-binding indications of interest from potential investors for the Placing during a pre-marketing process and certain investors have entered into the Subscription Letters. The number of Placing Shares will be agreed between the Company and Panmure Gordon at the close of the Bookbuild. Details of the number of Placing Shares and Subscription Shares and the approximate gross proceeds of the Placing and Subscription will be announced as soon as practicable after the closing of the Bookbuild.

Details of the Open Offer

The Company is proposing to raise up to a further GBP2.0 million before expenses by the issue of up to 16,666,667 Open Offer Shares under the Open Offer at the Issue Price, payable in full on acceptance. Any entitlements to Open Offer Shares not subscribed for by Qualifying Shareholders will be available to Qualifying Shareholders under the Excess Application Facility. The balance of any Open Offer Shares not subscribed for under the Excess Application Facility will not be available to the Placees under the Placing or the subscribers pursuant to the Subscription.

The terms and condition of the Open Offer will be set out in the Circular to Shareholders. The Open Offer is not underwritten. It is expected that the Circular will be despatched on or around 19 April 2018 and will also be available at this time on the Company's website at www.scancell.co.uk.

Effect of the Placing, Subscription and Open Offer

At least 50,000,000 Placing Shares and Subscription Shares are expected to be issued on or around 20 April 2018, conditional on First Admission respectively. Assuming completion of the Placing and Subscription and full take up of all Open Offer Shares offered under the Open Offer, upon Second Admission, the Enlarged Share Capital is expected to be 378,724,765 Ordinary Shares.

Details of the Placing

Panmure Gordon has entered into the Placing and Open Offer Agreement with the Company under which Panmure Gordon has, on the terms and subject to the conditions set out therein, undertaken to use its reasonable endeavours to procure, as the Company's agent, broker and bookrunner for the purpose of the Placing, subscribers for the Placing Shares at the Issue Price.

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

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

The Placing is conditional upon, inter alia:

   (a)              First Admission becoming effective; 

(b) the Subscription Letters becoming unconditional in accordance with their terms (save for any condition relating to First Admission) and the subscription funds being received by the Company prior to First Admission; and

(c) the obligations of Panmure Gordon under the Placing and Open Offer Agreement not having been terminated in accordance with its terms.

The Open Offer is conditional upon, inter alia:

(d) the Circular being sent to Qualifying Shareholders. A copy of the Circular will be available from the Company's website at http://www.scancell.co.uk;

   (e)              Second Admission becoming effective; and 

(f) the obligations of Panmure Gordon under the Placing and Open Offer Agreement not having been terminated in accordance with its terms.

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

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

Lock up

As part of the Placing, the Company has agreed that it will not issue or sell any Ordinary Shares for a period of 120 days after the latest Admission without the prior written consent of Panmure Gordon. That agreement is subject to the customary exception of granting options under, and allotting and issuing Ordinary Shares in the ordinary course pursuant to, the Company's existing share schemes.

Applications for admission to trading

Applications will be made to the London Stock Exchange for First Admission and Second Admission. It is expected that settlement of the Placing Shares and First Admission will become effective on or around 20 April 2018 and that dealings in the Placing Shares will commence at that time, and that settlement of the Open Offer Shares and Second Admission will become effective on or around 9 May 2018 and that dealings in the Open Offer Shares will commence at that time.

Bookbuild

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

Participation in, and principal terms of, the Placing

1. Panmure Gordon is arranging the Placing as placing agent, broker and bookrunner of the Company for the purpose of using its reasonable endeavours to procure Placees at the Issue Price for the Placing Shares.

2. Participation in the Placing will only be available to persons who may lawfully be, and are, invited to participate by Panmure Gordon. Panmure Gordon and its affiliates may participate in the Placing as principal.

3. This Appendix gives details of the terms and conditions of, and the mechanics of participation in, the Placing. No commissions will be paid to Placees or by Placees in respect of any Placing Shares.

4. The Bookbuild will establish the number of Placing Shares to be issued, which will both be agreed between Panmure Gordon 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 Panmure Gordon. Each bid should state the number of Placing Shares which the prospective Placee wishes to subscribe for. Bids may be scaled down by Panmure Gordon on the basis referred to in paragraph 9 below.

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

7. Each Placee's allocation will be confirmed to Placees orally by Panmure Gordon, and evidenced by a trade confirmation or contract note which will be dispatched as soon as practicable thereafter. The terms of this Appendix will be deemed incorporated by reference therein. The oral 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 Panmure Gordon and the Company, under which it agrees to acquire the number of Placing Shares allocated to it at the Issue Price on the terms and conditions set out in this Appendix and in accordance with the Company's articles of association. Except as required by law or regulation, no press release or other announcement will be made by Panmure Gordon or the Company using the name of any Placee (or its agent), in its capacity as Placee (or agent), other than with such Placee's prior written consent.

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

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

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

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

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

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

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

Conditions of the Placing

Panmure Gordon's obligations under the Placing and Open Offer Agreement in respect of the Placing Shares are conditional on, inter alia:

(c) First Admission taking place not later than 8.00 a.m. (London time) on 20 April 2018.

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

(a) the Company allotting, subject only to Second Admission, the Open Offer Shares in accordance with the Placing and Open Offer Agreement; and

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

Neither Panmure Gordon 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 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 Panmure Gordon.

Right to terminate under the Placing and Open Offer Agreement

Panmure Gordon is entitled in its absolute discretion, at any time before First Admission, to terminate the Placing and Open Offer Agreement by giving notice to the Company in the following circumstances:

(a) in the opinion of Panmure Gordon (acting in good faith), the warranties given by the Company to Panmure Gordon are not true and accurate or have become misleading (or would not be true and accurate or would be misleading if they were repeated at any time before First Admission) by reference to the facts subsisting at the time when the notice referred to above is given, in each case in a way that is material in the context of the Capital Raise and/or Admission; or

(b) in the opinion of Panmure Gordon (acting in good faith), the Company fails to comply with any of its obligations under the Placing and Open Offer Agreement and that failure is material in the context of the Capital Raise and/or Admission; or

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

(d) there has been a change in national or international financial, political, economic or stock market conditions (primary or secondary); an incident of terrorism, outbreak or escalation of hostilities, war, declaration of martial law or any other calamity or crisis; a suspension or material limitation in trading of securities generally on any stock exchange; any change in currency exchange rates or exchange controls or a disruption of settlement systems or a material disruption in commercial banking, in each case as would be likely in the opinion of Panmure Gordon (acting in good faith) to materially prejudice the success of the Capital Raise.

Following First Admission, the Placing and Open Offer Agreement is not capable of termination to the extent that it relates to the Placing. Following Second Admission, the Placing and Open Offer Agreement is not capable of termination to the extent that it relates to the Placing, Subscription or the Open Offer.

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

No admission document or prospectus

The Placing Shares are being offered to a limited number of specifically invited persons only and will not be offered in such a way as to require an admission document or prospectus in the United Kingdom or in any other jurisdiction. No offering document, admission document or prospectus has been or will be submitted to be approved by the FCA or submitted to the London Stock Exchange in relation to the Placing, and Placees' commitments will be made solely on the basis of the information contained in the Announcement (including the Appendices) and the Exchange Information (as defined further below). Each Placee, by accepting a participation in the Placing, agrees that the content of this Announcement is exclusively the responsibility of the Company and confirms that it has neither received nor relied on any other information (other than the Exchange Information (defined below)), representation, warranty, or statement made by or on behalf of the Company, Panmure Gordon, or any other person and neither Panmure Gordon, the Company nor any other person will be liable for any Placee's decision to participate in the Placing based on any other information, representation, warranty or statement which the Placees may have obtained or received and, if given or made, such information, representation, warranty or statement must not be relied upon as having been authorised by Panmure Gordon, the Company, or their respective officers, directors, employees or agents. Each Placee acknowledges and agrees that it has relied on its own investigation of the business, financial or other position of the Company in accepting a participation in the Placing. Neither the Company nor Panmure Gordon is making any undertaking or warranty to any

Placee regarding the legality of an investment in the Placing Shares by such Placee under any legal, investment or similar laws or regulations. Each Placee should not consider any information in this Announcement to be legal, tax or business advice. Each Placee should consult its own solicitor, tax adviser and financial adviser for independent legal, tax and financial advice regarding an investment in the Placing Shares. Nothing in this paragraph shall exclude the liability of any person for fraudulent misrepresentation.

Registration and settlement

Settlement of transactions in the Placing Shares (ISIN: GB00B63D3314) following First Admission will take place within CREST, provided that, subject to certain exceptions, Panmure Gordon reserves the right to require settlement for, and delivery of, the Placing Shares (or a portion thereof) to Placees by such other means that it deems necessary if delivery or settlement is not possible or practicable within CREST within the timetable set out in this Announcement or would not be consistent with the regulatory requirements in any Placee's jurisdiction.

Following the close of the Bookbuild, each Placee allocated Placing Shares in the Placing will be sent a trade confirmation or contract note stating the number of Placing Shares allocated to it at the Issue Price, the aggregate amount owed by such Placee to Panmure Gordon (as agent for the Company) and settlement instructions. Each Placee agrees that it will do all things necessary to ensure that delivery and payment is completed in accordance with either the CREST or certificated settlement instructions that it has in place with Panmure Gordon. Settlement will be through Panmure Gordon against CREST participant account: 83801. For the avoidance of doubt, Placing allocations are expect to be booked with a trade date of 18 April 2018 and settlement date of 20 April 2018 on a T+2 basis in accordance with the instructions set out in the trade confirmation.

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

If a Placee wishes to receive its Placing Shares in certificated form, it should contact Panmure Gordon (020 7886 2902) as soon as possible after receipt of its trade confirmation or contract note.

Placees who wish to receive their Placing Shares in certificated form are expected to receive their certificates for their Placing Shares by no later than 4 May 2018, provided payment in full has been made.

Interest is chargeable daily on payments not received from Placees on the due date in accordance with the arrangements set out above at the rate of two percentage points above LIBOR as determined by Panmure Gordon.

Each Placee is deemed to agree that, if it does not comply with these obligations, Panmure Gordon may sell any or all of the Placing Shares allocated to that Placee on such Placee's behalf and retain from the proceeds, for Panmure Gordon's account and benefit (as agent for the Company), an amount equal to the aggregate amount owed by the Placee plus any interest due. The relevant Placee will, however, remain liable and shall indemnify Panmure Gordon (as agent for the Company) on demand for any shortfall below the aggregate amount owed by it and may be required to bear any stamp duty or stamp duty reserve tax or securities transfer tax (together with any interest or penalties) which may arise upon the sale of such Placing Shares on such Placee's behalf. By communicating a bid for Placing Shares to Panmure Gordon, each Placee confers on Panmure Gordon all such authorities and powers necessary to carry out any such sale and agrees to ratify and confirm all actions which Panmure Gordon lawfully takes in pursuance of such sale.

If Placing Shares are to be delivered to a custodian or settlement agent, Placees should ensure that the trade confirmation or 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 UK stamp duty or stamp duty reserve tax or securities transfer tax. Placees will not be entitled to receive any fee or commission in connection with the Placing.

36. to the fullest extent permitted by law, it acknowledges and agrees to the disclaimers contained in the Announcement including the Appendices.

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

The agreement to settle a Placee's subscription (and/or the subscription of a person for whom such Placee is contracting as agent) free of stamp duty and stamp duty reserve tax depends on the settlement relating only to a subscription by it and/or such person direct from the Company for the Placing Shares in question. Such agreement assumes that the Placing Shares are not being subscribed for in connection with arrangements to issue depositary receipts or to transfer the Placing Shares into a clearance service. If there are any such arrangements, or the settlement relates to any other subsequent dealing in the Placing Shares, stamp duty or stamp duty reserve tax may be payable, for which neither the Company nor Panmure Gordon will be responsible, and the Placee to whom (or on behalf of whom, or in respect of the person for whom it is participating in the Placing as an agent or nominee) the allocation, allotment, issue or delivery of Placing Shares has given rise to such UK stamp duty or stamp duty reserve tax undertakes to pay such UK stamp duty or stamp duty reserve tax forthwith and to indemnify on an after-tax basis and to hold harmless the Company and Panmure Gordon in the event that any of the Company or Panmure Gordon has incurred any such liability to UK stamp duty or stamp duty reserve tax. If this is the case, each Placee should seek its own advice and notify Panmure Gordon accordingly.

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

Each Placee, and any person acting on behalf of the Placee, acknowledges that Panmure Gordon does not owe any fiduciary or other duties to any Placee in respect of any representations, warranties, undertakings or indemnities in the Placing and Open Offer Agreement.

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

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

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