('ReNeuron', the 'Group' or the 'Company')

Proposed Placing, Subscription and Open Offer

ReNeuron Group plc (AIM: RENE.L), a UK-based global leader in the development of cell-based therapeutics, announces its intention to raise gross proceeds of up to £13.9 million by means of a placing to institutional and other investors (the 'Placing') and a direct subscription with the Company to raise gross proceeds of up to £1.1 million (the 'Subscription'), in each case at a price of 70 pence per share ('Issue Price'). The net proceeds of the Placing and Subscription will allow the Group, inter alia, to deliver extended clinical data from its ongoing retinitis pigmentosa (RP) Phase 2a study and to deliver proof-of-concept pre-clinical data from ongoing exosome collaborations which could enable potential out-licensing deals, as detailed below more fully.

In addition, in order to provide all Qualifying Shareholders who do not take part in the Placing with an opportunity to participate in the proposed issue of new ordinary shares of one pence each in the capital of the Company, the Company also announces an Open Offer to raise up to a further £2.5 million (the Placing, Subscription and Open Offer together being the 'Transaction', and the new ordinary shares proposed to be issued pursuant to the Transaction being the 'New Shares').

The Placing will be conducted through an accelerated bookbuilding process (the 'Bookbuild') which will be launched immediately following this Announcement. The Placing is subject to the terms and conditions set out in Appendix II to this Announcement.

Subject to successful closing of the Bookbuild, the Open Offer will be made of up to 3.5 million Open Offer Shares on the basis of 1 Open Offer Share for every 9 Existing Ordinary Shares held by Qualifying Shareholders at the Record Date.

· The directors of the Company (the 'Directors' or the 'Board') intend to subscribe for, in aggregate, a total of £1.1 million for 1,507,142 New Shares in the Subscription at the Issue Price.

· The Company has received regulatory approval in both the US and UK to expand its ongoing Phase 2a study in further patients at a higher dose level in those territories, with further readouts from the expanded study expected over the next 12 months

· Three collaboration agreements signed with major pharmaceutical/biotechnology companies to explore the potential of the Company's exosomes to deliver therapeutic agents to the brain, with proof-of-concept pre-clinical data results expected in H1 2021

· The net proceeds of the Placing and Subscription,together with the Company's existing cash resourcesare expected, in the opinion of the Directors,to extend its cash runway for at least the period of 18 months following the date of Admission

The Placing, Subscription and the issue of the Open Offer Shares are conditional, inter alia, on the passing by Shareholders of certain resolutions at the General Meeting, which is being convened, due to the current COVID-19 'stay at home measures', as a closed meeting with the minimum number of Shareholders legally required to be present, for 10.00 a.m. on 11 December 2020.

A circular which will provide further details of the Transaction and include a notice convening the General Meeting (the 'Circular'), is expected to be sent to Shareholders and be available on the Company's website (http://www.reneuron.com/) on or around 24 November 2020.

The Placing Shares and the Subscription Shares are not being made available to the public and the Open Offer Shares will only be available to Qualifying Shareholders. The Placing and Open Offer are not being underwritten.

The New Shares, assuming full take-up of the Open Offer, will represent approximately 43.9per cent. of the Enlarged Share Capital following Second Admission.

The Issue Price is at a discount of approximately 27.8 per cent to the mid-market closing price of an existing ordinary share on 20 November 2020.

Stifel is acting as broker and sole bookrunner in relation to the Placing and as nominated adviser.

Set out below in Appendix I is an adapted extract from the draft Circular that is proposed to be sent to Shareholders after the closure of the Bookbuild.

APPENDIX I - EXTRACTS FROM THE CIRCULAR

The Placing, Subscription and Open Offer

1. Introduction

Today, 23 November 2020, the Company announces its intention to raise up to £15.0 million (before fees and expenses) by way of the Placing and Subscription and up to £2.5 million (before fees and expenses) by way of the Open Offer.

The Placing, Subscription and the issue of the Open Offer Shares are conditional, inter alia, on the passing by Shareholders of Resolutions 1 and 3 at the General Meeting, which is being convened for 10.00 a.m. on 11 December 2020.

As part of the Placing, the Company is seeking to raise funds by the issue of the EIS Placing Shares to investors seeking the benefit of tax relief under the EISand the VCT Placing Shares to investors seeking the benefit of tax relief through VCT.

Shareholders should note that although the Directors believe that the EIS Placing Shares should qualify for EIS Relief and that the issue of Ordinary Shares to a VCT should be regarded as a qualifying holding, no Advance Assurance has been received from HMRC, and consequently the availability of EIS Relief in relation to the EIS Placing Shares and whether OrdinaryShares issued to a VCT are a qualifying holdingcannot be guaranteed.

Application will be made to the London Stock Exchange for the EIS/VCT Placing Shares to be admitted to trading on AIM.It is expected that First Admission will become effective and that dealings in EIS/VCT Placing Shares will commence at 8.00 a.m. on 14 December 2020 (being the business day following the General Meeting). Application will be made to the London Stock Exchange for the General Placing Shares, the Subscription Shares and the Open Offer Shares to be admitted to trading on AIM.It is expected that Second Admission will become effective and that dealings in the General Placing Shares, the Subscription Shares and the Open Offer Shares will commence at 8.00 a.m. on 15 December 2020 (being the business day following First Admission).

If the conditions relating to the issue of the Placing Shares are not satisfied, or the Placing Agreement is terminated in accordance with its terms, the Placing Shares, the Subscription Shares andtheOpen Offer Shares will not be issued and the Company will not receive the related funds.

Shareholders should note that it is possible that First Admission occurs but that Second Admission does not. If Second Admission does not occur then the Company will not receive the relevant net proceeds in respect of such Second Admission and the Company may not be able to finance the activities referred to in this document.

Importance of the vote

Shareholders should be aware that if Resolutions 1 and 3 are not approved at the General Meeting, the Transaction will not complete and the Net Proceeds will not be received by the Company. If this were to happen, the Group would only have sufficient working capital to trade through to the end of April 2021 without taking any mitigating measures and the Directors may not be in a position to pursue further the commercial activities of the Group and in such circumstances would need to take steps to manage the Group's cash resources and protect the position of its creditors.

2. Background to and Reasons for the Transaction

Background to the Company

ReNeuron is a global leader in cell-based therapeutics, harnessing its unique stem cell technologies to develop 'off the shelf' stem cell treatments, without the need for immunosuppressive drugs. The Company's clinical-stage candidates are in development for the blindness-causing disease, retinitis pigmentosa, and, via regional partnerships, for disability as a result of stroke.

ReNeuron is also advancing its proprietary exosome technology platform as a potential delivery system for drugs that treat diseases of the brain. The Company also has the ability through its conditionally immortalised induced pluripotent stem cell (iPSC) platform to make any tissue cells of choice; in-house programmes are focused on treatments for blood cancers and diabetes.

Use of Proceeds

Pursuant to the Transaction, the Company proposes to raise a minimum of £15.0 million (before expenses) primarily to fund the extension of its Phase 2a clinical study of hRPC in retinitis pigmentosa, to continue to progress its exosome and iPSC programmes, and for general working capital purposes. The Company forecasts that the Net Proceeds raised from the Transaction, together with its existing resources, will extend its cash runway for at least the period of 18 months following the date of Admission.

The Directors intend to use the Net Proceeds as follows:

RP Phase 2a extended clinical trial, including clinical & regulatory support

£3.4 million

RP IVTpre-clinical programme

£1.6 million

Exosome & iPSC programmes - drug delivery collaborations

£2.3 million

Manufacturing & QA/QC, including process development and technology transfer in support of RP clinical study

£4.4 million

Facilities

£1.6 million

General and administrative costs

£2.8 million

R&D tax credit, revenue from assumed crystallisation of licence milestone & working capital movements(1)

£(2.0) million

Total

£14.1 million

(1) Total net proceeds of £14.1 million include assumed operational net cash inflows of £2.0 million in the period from May 2021 to the end of March 2022, based on the Company's current expectations, incorporating a R&D tax credit in respect of the 2020/21 tax year of £1.7 million, the crystallisation of a milestone from Fosun Pharma of net £0.9 million less an assumed £0.6 million working capital reduction.

Including the disclosed net operational cash inflows disclosed directly above, the Company's cash forecasts in the full period from the date of this document to the end of March 2022 include an additional net £1.0 million cash inflow, comprising a potential crystallisation of a regulatory milestone, totalling a net £0.9 million cash inflow in relation to the exclusive licence agreement signed with Shanghai Fosun Pharmaceutical Industrial Development Co., Ltd. ('Fosun Pharma') (the 'Fosun Licence'), two R&D tax credits totalling £4.6 million and net negative working capital movements of £(4.5) million primarily in relation to ongoing run-off costs from legacy studies, which represent accrued expenses which will have to be paid out of the Group's existing cash balance.

3. Current Trading and Outlook

The Company expects to announce its interim results for the six months ended 30 September 2020 on 24 November 2020. Cash, cash equivalents and bank deposits at 30 September 2020 were £9.8 million (31 March 2020: £12.6 million) and ongoing operating costs have been reduced due to the Company's decision to focus its in-house activities on its retinal disease and exosome-based programmes.

During the past 20 months, the Company has continued to announce and present encouraging positive efficacy data from the ongoing US Phase 2a clinical trial of its hRPC cell therapy candidate in retinitis pigmentosa.

As previously reported, the degree of efficacy observed varies between patients. Since the last data set was announced on 29 June 2020, a further three patient data points have been observed, including two further patients at 12 months post treatment, and one further patient at 18 months post treatment. The latest mean results are set out in the table below.

Two patients have so far been assessed at 18 months:

Patient One: + 17 letters in treated eye, +1 letter in untreated eye

Patient Two: +6 letters in treated eye, + 22 letters in untreated eye

In addition, the Company received regulatory approvals in both the US and the UK to pursue this study in further patients at a higher dose level in those territories and expects to present further data from this extended study over the next 12 months, including six month data from the additional nine patients planned to be treated at the higher dose level. On 10 September 2020, the Company announced that patient dosing had now commenced in the US in this expanded Phase 2a clinical trial.

Additionally, the Company's exosome and iPSC cell technologies research continues to progress and the Company is targeting further collaboration agreements in the near term to complement the agreements it has already signed with major pharmaceutical/biotechnology companies regarding its exosome programme. It expects to announce initial proof of concept pre-clinical data from its exosome platform current research collaborations in H1 2021.

Action to be taken

In respect of the General Meeting

Shareholders will not be allowed to attend the General Meeting in light of the Covid-19 situation and the Stay at Home measures that have been implemented by the UK Government.

Recommendation

Your Directors consider that the Transaction and the authorities granted by the Resolutions are in the best interests of the Company and its Shareholders as a whole. Accordingly, your Directors unanimously recommend that you vote in favour of the Resolutions as they intend to do in respect of their own shareholdings of 903,577 Ordinary Shares, representing approximately 2.83 per cent. of the Company's existing issued ordinary share capital.

In particular, none of the Company, Stifel or any of their respective affiliates, agents, directors, officers or employees shall have any liability (including to the fullest extent permissible by law, any fiduciary duties) in respect of Stifel's conduct of the Bookbuild and the Placing. Each Placee acknowledges and agrees that the Company is responsible for the allotment of the Placing Shares to the Placees and neither Stifel nor any of its affiliates, agents, directors, officers or employees shall have any liability to the Placees for the failure of the Company to fulfil those obligations.

Conditions of the Placing

Stifel's obligations under the Placing Agreement in relation to the EIS/VCT Placing are conditional on, inter alia:

(a) the Company allotting, subject only to First Admission, the EIS/VCT Placing Shares in accordance with the Placing Agreement;

(b) the passing (without amendment) of the Resolutions at the General Meeting; and

(c) First Admission occurring on or before 8.00 a.m. on 14 December 2020, and the Placing Agreement not having been terminated prior First Admission or such later time and/or date, being no later than 8.00 a.m. on 31 December 2020, as the Company may agree with Stifel.

Stifel's obligations under the Placing Agreement in relation to the General Placing are conditional on, inter alia:

(a) First Admission having occurred;

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

(c) Second Admission occurring on or before 8.00 a.m. on 15 December 2020, and the Placing Agreement not having been terminated prior Second Admission or such later time and/or date, being no later than 8.00 a.m. on 31 December 2020, as the Company may agree with Stifel.

Stifel's obligations under the Placing Agreement are also conditional on, inter alia, in the sole judgement of Stifel, there not having occurred since the date of the Placing Agreement any material adverse change in the condition (financial, operational, legal or otherwise), earnings, business, trading position, management, properties, assets, rights, results of operations, shareholders' funds or prospects of the Group as a whole ('Material Adverse Effect').

If (i) any of the conditions contained in the Placing Agreement are not fulfilled or waived by Stifel in writing by the time or date where specified (or such later time or date as the Company and Stifel may agree, not being later than 8.00 a.m. on 31 December 2020), or (ii) the Placing 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. For the avoidance of doubt the Placing shall not be conditional on the Open Offer being subscribed for by Qualifying Shareholders. In the event that any of the conditions in respect of Second Admission are not satisfied (or waived) or have become incapable of being satisfied on or before 31 December 2020, to the extent the EIS/VCT Placing Shares have been allotted and issued to Placees, and the Placing Agreement is terminated after First Admission but prior to Second Admission, then the rights and obligations of the relevant Placees in respect of First Admission will survive termination of the Placing Agreement, but the relevant Placees' rights and obligations in respect of Second Admission shall cease and determine at such time.

Stifel may, in its absolute discretion, waive the whole or any part of any of the Company's obligations in relation to the conditions in the Placing Agreement, save that certain conditions, including the condition relating to the passing of the Resolutions at the General Meeting, Admission taking place and the Company allotting the Placing Shares subject only to Admission taking place, and the time by which these must occur, may not be waived and the period for compliance with such conditions may not be extended. Any such waiver will not affect Placees' commitments as set out in this Announcement.

None of Stifelor the Company, nor any of their respective affiliates, agents, directors, officers or employees, shall have any liability to any Placee (whether in respect of First Admission or Second Admission) (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 Stifeland the Company.

Right to terminate under the Placing Agreement

Stifelis entitled in its absolute discretion, at any time before First Admission or Second Admission, to terminate the Placing Agreement by giving notice to the Company in certain circumstances, including, inter alia:

(a) in the sole judgement of Stifel (acting in good faith), if any warranty in the Placing Agreement would if repeated at any time up to First Admission or Second Admission (by reference to the facts and circumstances then existing) be untrue or inaccurate or misleading;

(b) in the sole judgement of Stifel(acting in good faith), there has occurred a breach by the Company of any of its obligations under the Placing Agreement;

(c) in the sole judgement of Stifel(acting in good faith), there has occurred any Material Adverse Effect since the date of the Placing Agreement or there is a fact, circumstance or development reasonably likely to result in a Material Adverse Effect; or

(d) there has been an outbreak of hostilities; an incident of terrorism; a material deterioration in, or material escalation in the response to, the Covid-19 pandemic; a declaration of a state of emergency or martial law or other calamity or crisis, national or international emergency or war; any change in national or international monetary, political, financial or economic conditions or currency exchange rates or foreign exchange controls; a suspension or material limitation in trading of securities generally on the London Stock Exchange, the New York Stock Exchange or NASDAQ; a material disruption of commercial banking or settlement or clearance services in the United States, Asia or in Europe; or any other adverse change (or prospective adverse change) in the United Kingdom regarding taxation affecting the Shares, in each case as would be likely in the sole judgement of Stifel(acting in good faith) to prejudice the success of the Placing, dealings in the Shares in the secondary market or which makes it, in the sole judgement of Stifel(acting in good faith), impractical to proceed with the Placing.

Following Second Admission, the Placing Agreement is not capable of termination.

The rights and obligations of the Placees shall terminate only in the circumstances described in these terms and conditions and in the Placing 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 Stifel of any right of termination or other discretion under the Placing Agreement shall be within the absolute discretion of Stifel, 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 Stifel, the Company or any of their respective directors or employees under the Placing 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 this Appendix) 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), representation, warranty, or statement made by or on behalf of the Company, Stifel, any of their respective affiliates, agents, directors, officers or employees, or any other person and neither Stifel, the Company, any of their respective affiliates, agents, directors, officers or employees 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 Stifel, 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 Stifel are 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: GB00BF5G6K95) following First Admission and Second Admission will take place within CREST provided that, subject to certain exceptions, Stifel reserves the right to require settlement for, and delivery of, the Placing Shares (or a portion thereof) to Placees by such other means that they deem 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 for the Placing, each Placee allocated Placing Shares in the Placing will be sent a Contract Note stating the number of Placing Shares allocated to it at the Issue Price, the aggregate amount owed by such Placee to Stifel (as agent for the Company) or its sub-agent 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 Stifel or its sub-agent.

It is expected that settlement in respect of the (i) the EIS/VCT Placing Shares will be on 14 December 2020 on a T+20 basis; and (ii) the General Placing Shares will be on 15 December 2020 on a T+21 basis, in each case in accordance with the instructions set out in the Contract Note.

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 Stifel.

Each Placee is deemed to agree that, if it does not comply with these obligations, Stifel may sell any or all of the Placing Shares allocated to that Placee on such Placee's behalf and retain from the proceeds, for Stifel's account and benefit (as agents 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 Stifel (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, each Placee confers on Stifel all such authorities and powers necessary to carry out any such sale and agrees to ratify and confirm all actions which Stifel 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 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.

Representations, warranties and further terms

By submitting a bid and/or participating in the Placing each Placee (and any person acting on such Placee's behalf) makes the following representations, warranties, acknowledgements, agreements and undertakings (as the case may be) to the Company and Stifel (including its sub-agent), namely that, each Placee (and any person acting on such Placee's behalf):

36. agrees to indemnify on an after-tax basis and hold the Company, Stifel and their respective affiliates 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 in this Appendix and further agrees that the provisions of this Appendix shall survive after completion of the Placing;

It has relied upon its own examination and due diligence of the Company and its associates taken as a whole, and the terms of the Placing, including the merits and risks involved;

40. acknowledges that its commitment to subscribe for Placing Shares on the terms set out herein and in the Contract Note will continue notwithstanding any amendment that may in future be made to the terms of the Placing and that Placees will have no right to be consulted or require that their consent be obtained with respect to the Company's conduct of the Placing;

41. acknowledges that Stifel, or any of its affiliates acting as an investor for their own account may take up shares in the Company and in that capacity may retain, purchase or sell for their own account such shares and may offer or sell such shares other than in connection with the Placing;

42. represents and warrants that, if it is a pension fund or investment company, its purchase of Placing Shares is in full compliance with all applicable laws and regulation; and

43. to the fullest extent permitted by law, it acknowledges and agrees to the disclaimers contained in the Announcement including this Appendix.

The representations, warranties, acknowledgments and undertakings contained in this Appendix are given to Stifel 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 none of the Company or Stifel 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 Stifel in the event that any of the Company or Stifel 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 Stifel 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 Stifel does not owe any fiduciary or other duties to any Placee in respect of any representations, warranties, undertakings or indemnities in the Placing Agreement.

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

When a Placee or person acting on behalf of the Placee is dealing with Stifel, any money held in an account with Stifel 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 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 Stifel money in accordance with the client money rules and will be used by Stifel in the course of its own business and the Placee will rank only as a general creditor of Stifel.

All times and dates in this Announcement may be subject to amendment. Stifel 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.
