Proposed Placing to raise a minimum of £10 million

Net proceeds of the placing will support the expansion of the Company's business and accelerate the Company's growth strategy

Maryland, US - 7.00 a.m., 5 February 2019: MaxCyte (LSE: MXCT), the global cell-based medicines and life sciences company, announces today a proposed conditional placing to raise a minimum of £10.0 million before expenses (the "Placing") at a price of 170 pence per share, via a placing of a minimum of approximately 5,882,352 million new shares of Common Stock of the Company (the "New Common Stock"), representing approximately 11.46 per cent. of the Company's existing Common Stock, to current and new institutional and other investors. Panmure Gordon (UK) Limited ("Panmure Gordon") is acting as Financial Adviser, Nominated Adviser and sole Broker to the Company.

The Directors intend to use the net proceeds of the Placing receivable by the Company from the issue of the New Common Stock to accelerate the Company's growth strategy and execute on the significant commercial opportunities available, including:

I. Expansion of the cell therapy pipeline and acceleration of high-value clinical and commercial deals in a diverse range of fields, including immuno-oncology, gene editing and regenerative medicine;

II. Investments in the expansion of the core customer base and instrument business, including new product development and applications in large-scale biopharmaceutical transient protein manufacturing; and

III. Advancement of the CARMA pipeline for the treatment of solid tumors including an intravenous ("IV") administration programme.

The Company remains focused on advancing the potentially high value CARMA programme where the Board believes there is a significant opportunity for MaxCyte. MaxCyte is expanding its next-generation CAR therapy programme for potential use in additional solid and hematological cancer indications, in particular including an IV administration CARMA programme ("IV Programme") which is currently in pre-clinical development. As summarised above, the net proceeds of the Placing will be used to, amongst other things, advance the IV Programme with the intention of filing an IND for the study and commencing a Phase I trial in 2019 targeting a range of additional solid tumours including potentially, non-small cell lung cancer and bile duct cancer. Completion of the Phase I CARMA programme for ovarian cancer and peritoneal mesothelioma using intraperitoneal injection which is currently underway, is expected in H1 2020.

MaxCyte is also continuing to expand its operations across the fast-growing bioprocessing and cell therapy markets and MaxCyte's Board anticipates continued strong growth for the current 2019 financial year in particular driving top-line growth through further investment in sales and marketing. The Company will continue to invest in product development to be at the forefront of the cell therapy revolution and to enable its parties to commercialise novel cell based medicines.

Subject to investor demand for the Placing and in order to increase the liquidity of the Common Stock, for the benefit of all Stockholders and to provide an orderly partial exit for certain long-standing Stockholders, the Company has also sought to enable any excess market demand by a sale of up to 320,223 shares of Sale Stock by certain unconnected, non-PDMR Stockholders, concurrent with the Placing and also at the Placing Price (the "Vendor Placing").

Subject to investor demand for the Placing the Company may also issue up to 50,417 shares of Common Stock pursuant to the cashless exercise of options by certain unconnected stockholders and non-PDMR option holders, concurrent with the Placing and also at the Placing Price (the "Option Issue").

The net proceeds of Option Issue will be paid to the option holders and the net proceeds of the Vendor Placing will be paid to the selling Stockholders.

Doug Doerfler, President & Chief Executive Officer, said: "Since listing on AIM in 2016, we have continued to make significant progress across all areas of the business, supporting our biopharmaceutical partners in developing new classes of medicines for patients with inherited genetic diseases, infectious diseases and cancer. We've also made important progress with our high-value CARMA immuno-oncology platform, advancing MCY-M11, our wholly owned lead therapeutic candidate, into the clinic in 2018 in our US-based Phase I clinical trial and validating our innovative one-day manufacturing process. We look forward to the future with great confidence."

The Placing, Vendor Placing and the Option Issue will be conducted by way of an accelerated bookbuilding process (the "Bookbuild") which will be launched immediately following this announcement in accordance with the terms and conditions set out in Appendix II. The Placing Common Stock are not being made available to the public. It is envisaged that the Bookbuild will be closed no later than 6.30 p.m. today, 5 February 2019. Details of the number of Placing Common Stock, the approximate gross proceeds of the Placing and the outcome of the Vendor Placing and Option Issue will be announced as soon as practicable after the closing of the Bookbuild. The Placing, Vendor Placing and the Option Issue will not be underwritten.

The Placing is conditional upon, inter alia, the approval of the relevant Resolutions by Stockholders at the Special Meeting to be held at 11.00 a.m. (EDT) / 4.00 p.m. (GMT) on 26 February 2019 at 21 Firstfield Road, Suite 202, Gaithersburg, Maryland 20878, United States. Certain of the New Common Stock (the "Eligible New Common Stock") will be offered to VCTs and to those investors seeking to claim EIS relief in relation to their investment. The remaining New Common Stockand the Option Stock issued pursuant to the Option Issue (the "General New Common Stock") will be offered to those investors who are neither seeking EIS relief nor are VCTs. EIS and VCT investors should note that it is intended that admission of the Eligible New Common Stock to trading on AIM (expected to be on 28 February 2019 ("First Admission")) will occur on the business day immediately before admission of the General New Common Stock to trading on AIM (expected to be on 1 March 2019 ("Second Admission")). EIS and VCT investors should also note that the Company has the right, following consultation with Panmure Gordon, to reduce the number of Eligible New Common Stock to be issued by such amount as has an aggregate value at the Placing Price of no more than £700,000 if the exchange rate for British Pounds to US Dollars immediately prior to First Admission has an adverse impact on the availability of EIS and VCT relief. A circular to Stockholders convening the requisite Special Meeting is expected to be posted shortly. The Vendor Placing is conditional on the Placing.

Upon Admission, the New Common Stock will trade in the Company's new restricted line of Common Stock under the symbol MXCS, and the New Common Stock, as represented by Depository Interests, will be held in the CREST system and will be segregated into a separate trading system within CREST identified with the marker "REG S" and ISIN USU575801175. The Company also maintains an unrestricted line of Common Stock trading under the existing symbol MXCT. The Sale Stock will trade under the existing symbol MXCT and ISIN US57777K1060.

Proposed Placing and Notice of Special Meeting

Company information and background

Company overview

MaxCyte is a global cell-based medicines and life sciences company applying its patented cell engineering technology to help patients with high unmet medical needs in a broad range of conditions. MaxCyte is developing novel CARMA™ therapies. CARMA is MaxCyte's mRNA-based proprietary platform for autologous cell therapy. MaxCyte is advancing the clinical development of CARMA via a non-randomized, open label, dose-escalation Phase 1 clinical trial currently at two clinical sites participating in the study (the National Cancer Institute at the National Institutes of Health ("NIH") and Washington University at St. Louis).

In addition, through its core business, the Company leverages its Flow Electroporation™® Technology platform to enable its biopharmaceutical industry partners to advance the development of innovative, cutting-edge medicines, particularly in cell therapy, including the use of gene editing tools in the treatment of inherited genetic diseases and immuno-oncology/allogeneic approaches to treating cancer. The Company has placed its cutting-edge flow electroporation instruments worldwide, including with ten of the top ten global biopharmaceutical companies, and has more than 70 partnered program licenses in cell therapy including more than 35 licensed for clinical use. With its robust delivery technology, MaxCyte helps its partners to unlock the full potential of their products.

Leading the Future of Cell-Based Medicines Through Investments in MaxCyte's Discovery Platform & Infrastructure

The use of MaxCyte's technology across a broad variety of next-generation therapies such as various immunotherapy and gene editing approaches, demonstrates the significant potential addressable market of the technology. The Company's technology is licensed to partners to enable the development of new generation cell therapies, providing the Company with significant recurring annual license fees, which are complemented by an attractive recurring revenue stream from the sale of its proprietary single-use disposable processing assemblies (disposables). As cell-based therapeutic products progress through clinical development towards therapeutic product approval and commercialisation, the Company has the opportunity to enter into significantly higher value deals to provide commercial use rights to the developer.

The Company entered into its first non-exclusive commercial licence agreement in March 2017 with CRISPR Therapeutics and Casebia Therapeutics to develop CRISPR/Cas9-based therapies for haemoglobin-related and immunodeficiency diseases. In November 2018, the company entered into a second agreement with CRISPR Therapeutics providing CRISPR with non-exclusive development and commercial-use rights to develop immuno-oncology cell therapies. The Company entered into a further commercial licence agreement in Q4 2018 with Precision BioSciences ("Precision") to use MaxCyte's Flow Electroporation technologies to deliver Precision's proprietary ARCUS genome-editing technology for use in next-generation gene edited allogeneic T-cell immunotherapies designed to treat a broad range of cancers.

Pursuant to each of the commercial licence agreements, MaxCyte will supply its technology as part of the enabling technology license agreement for clinical and commercial use and will receive milestone and sales-based payments in addition to other licensing fees. The three commercial licences announced by the Company to date have potential aggregate milestone payments in excess of US$250 million. The Directors believe there is significant potential for further licencing and commercial agreements with its Cell Therapy customers.

In June 2017, the Company entered into a Cooperative Research and Development Agreement ("CRADA") with the NIH's National Institute of Allergy and Infectious Diseases to develop treatments for X-linked chronic granulomatous disease ("CGD") using next-generation gene correction leveraging CRISPR/Cas9 and MaxCyte's Flow Electroporation™® Platform. In addition, the Company announced a second CRADA with NIH in June 2018. Under this agreement, MaxCyte and the National Heart, Lung, and Blood Institute ("NHLBI"), part of the NIH, will aim to develop treatments for individuals with sickle cell disease ("SCD") using next-generation CRISPR/Cas9-based single-nucleotide correction enabled by MaxCyte's cell engineering platform. In the search for alternative therapies for SCD, NHLBI will conduct pre-clinical research evaluating the effectiveness and safety of CRISPR-Cas9 gene editing on models of SCD. MaxCyte will supply mRNA molecules and focus on leveraging its Flow Electroporation Technology to develop reliable and effective processes to produce clinically meaningful correction of mutated gene sequences. These collaborations between the Company and two institutes within the US NIH to advance new treatments for CGD and SCD reflect the MaxCyte platform's ability to provide unique enablement in the rapidly expanding field of gene editing.

The Company continues to make key advances in developing CARMA, its innovative, proprietary platform in immuno-oncology. CARMA allows less complex and rapid manufacture of advanced CAR-based cancer treatments that utilise a patient's own immune system and is differentiated from traditional CAR therapy due to its use of mRNA to engineer fresh (unmodified) patient immune cells. By utilising transient expression via mRNA delivery, CARMA has the potential to control over severe adverse side-effects seen in first-generation, viral-based CAR therapies, opening the high potency of CAR immunotherapies to a broader range of solid cancers than traditional CAR approaches, and to deliver precise therapies for patients significantly faster and without the cost, complexity and significant investment of virus-based CAR therapies that involve longer manufacturing time and require centralized manufacturing. Utilising the combination of MaxCyte's proprietary Flow Electroporation Technology, mRNA and fresh peripheral blood mononuclear cells, the Directors believe that the CARMA programme has the potential to impact diseases with high unmet medical need while addressing some of the most significant issues with current CAR-T therapies including challenging side effects as well as the complex, expensive and time-consuming manufacturing processes found in viral-based CAR therapies.

In October 2018, MaxCyte announced that the first patient had been dosed in its Phase I dose-escalation clinical trial in the United States with the Company's lead wholly-owned CAR therapeutic candidate, MCY-M11. The study is designed to evaluate MCY-M11, a mesothelin-targeting, first-in-class cell therapy for the treatment of solid cancers, in individuals with relapsed/refractory ovarian cancer and peritoneal mesothelioma. The results of this initial study have the potential to provide evidence for the safety and effectiveness of MCY-M11, the first CAR drug candidate developed from the CARMA platform. The trial is also designed to establish CARMA as a new autologous cell therapy platform for next generation targeted cell-based immune therapies. There have been no adverse events observed to date and completion of this Phase I trial is expected in H1 2020. The initiation of the dosing of patients with the first CARMA therapeutic also validates the Company's one day clinical manufacturing process.

In addition to commencement of the first CARMA clinical trial, additional significant accomplishments achieved by the Company in 2018 have included:

· Entered into a second non-exclusive clinical and commercial licence agreement with CRISPR Therapeutics to allow CRISPR Therapeutics to use MaxCyte's Flow Electroporation Technology to develop CRISPR/Cas9-based therapies in immuno-oncology;

· Entered into a non-exclusive, clinical and commercial license agreement with Precision BioSciences that will allow Precision to use MaxCyte's Flow Electroporation Technology to robustly deliver Precision's proprietary ARCUS genome-editing technology for use in next-generation gene edited allogeneic T-cell immunotherapies designed to treat a broad range of cancers;

· Entered into a research agreement with Kite, a Gilead Company. Under the terms of the agreement, Kite will use MaxCyte's Flow Electroporation Technology platform to enable non-viral cell engineering;

· Expanded the Company's cell therapy agreements to cover more than 70 cell therapy partnered programmes in cutting-edge fields and including more than 35 licensed for clinical use.

· Maintained ongoing collaborations with world leaders in the CAR field in both solid cancers and haematological malignancies, with nine academic clinical trials supported by MaxCyte's technology;

· Continued strong investment in sales and marketing capabilities to grow the Company's customer base, which now includes all of the top 10 (and 20 out of the top 25) global pharmaceutical companies;

· Presented at industry and scientific/medical conferences on MaxCyte's next-generation autologous CAR therapies, highlighting the Company's innvoative CARMA platform's ability to engineer transient persistence to mitigate off-tumor toxicity and significantly reduce the turnaround time of autologous cell therapy to patients;

· Entered into a CRADA with NIH's NHLBI to develop treatments for individuals with sickle cell disease using next-generation CRISPR/Cas9-based single-nucleotide correction enabled by MaxCyte's cell engineering platform; and

· Appointed new Claudio Dansky Ullmann, MD (in April 2018) as Chief Medical Officer to oversee the clinical development of CARMA. Dr. Dansky has over 25 years' of experience in clinical oncology and pharmaceutical research including at Takeda Pharmaceuticals and the National Cancer Institute at NIH.

Growth strategy

MaxCyte leverages its proprietary, high performance cell engineering platform to create high value relationships across the pharma and biotech industry. The consistency, scalability, ease of use and broad applicability of its technology enables users to solve significant technical and clinical challenges, accelerate timelines and achieve reliable and consistent results. The Company has successfully executed a growth strategy via direct marketing in the US and Europe and via distributors in Asia and Europe, which is characterized by long-term rapid growth in revenues, high margins and broad adoption of its technology globally including by all of the top 10 global pharmaceutical companies.

MaxCyte licenses its platform to developers of cell based therapeutics for research, clinical and commercial use, generating through those relationships more than 70 programmes licensed for research, clinical and/or commercial development. The Directors believe that i) cell therapy is a rapidly growing opportunity for the Company with over 800 companies developing cell and gene based therapies; ii) the Company will have significant revenue and value opportunities in the future from its current and future cell therapy customers; and iii) cell therapy customers provide growing recurring revenues from instruments license fees and repeat purchase of single-use consumables and, as their programs advance, the opportunity for significant milestone and sales based payments. The commercial licences announced to date by the Company have the potential, subject to the customers' successful progress, to deliver to MaxCyte milestone payments in excess of US$250 million in aggregate.

MaxCyte sells its Flow Electroporation® instruments and consumables for the drug discovery and development market in applications that include cell based assays for drug screening, rapid scalable protein production, bio-manufacturing and stable cell line development. The sale of consumables provides the Company with a recurring revenue stream which consistently accounts for a significant and growing proportion of the Group's total revenue. The Directors believe that instrument and related processing/consumable sales represent a significant growing revenue stream for MaxCyte.

MaxCyte's growth strategy has also focused on developing data to validate its CARMA platform in solid tumours and haematological malignancies and plans to generate human proof-of-concept data which will enable a significant number of high-value licensing deals for CARMA, its proprietary mRNA CAR therapeutic platform. The Company is developing CARMA through a pipeline of next-generation CAR therapies including via its strategic research collaborations with the NCI at the NIH and with the Washington University in St. Louis for its first product, MCY-M11. Recent commercial partnering deals which the Directors believe are reflective of those possible for CARMA include:

· Amgen and Kite: Ph I/II-ready oncology license, $525m milestones per product with $60m upfront payment;

· Pfizer and Cellectis: research oncology allogeneic license, 10% equity, milestones of $185m per target and $80m upfront payment; and

· Baxalta and Precision Biosciences: research haematological oncology allogeneic license, deal total of $1.6bn with $105m upfront payment.

MaxCyte is an established business with consistent growth and high gross margins underpinned by recurring revenues from instrumentation licenses and consumable sales and with significant upside from potential commercial licences that incorporate milestone and sales based payments as well as high value licence opportunities derived from the Company's CARMA platform.

Use of proceeds and reasons for the Placing

The Directors intend to use the net proceeds of the Placing receivable by the Company from the issue of the New Common Stock, to accelerate the Company's growth strategy across the business and to capitalise on the significant commercial opportunities available, including:

I. Expansion of the cell therapy pipeline and acceleration of high-value clinical and commercial deals in a diverse range of fields, including immuno-oncology, gene editing and regenerative medicine;

III. Advancement of the CARMA pipeline for the treatment of solid tumors including an intravenous administration programme;

The Company remains focused on advancing the potentially high value CARMA programme where the Board believes there is a significant opportunity for MaxCyte. MaxCyte is expanding its next-generation CAR therapy programme for potential use in additional solid and hematological cancer indications, in particular including an intravenous administration CARMA programme which is currently in pre-clinical development. As summarised above, the net proceeds of the Placing will be used to, amongst other things, advance the intravenous administration CARMA programme with the intention of filing an IND for the study and commencing a Phase I trial in 2019 targeting a range of additional solid tumours including potentially, non-small cell lung cancer and bile duct cancer. Completion of the Phase I CARMA programme for ovarian cancer and peritoneal mesothelioma using intraperitoneal injection which is currently underway, is expected in H1 2020.

EIS VCT

The Company received advance assurance on 21 November 2018 from HM Revenue & Customs ("HMRC) stating that it believes HMRC would be able to authorise the Company to issue compliance certificates under Section 204(1) Income Tax Act 2007 based on the information provided by the Company to HMRC. HMRC also confirmed that as a result of the consultation document on advance assurance HMRC's policy has changed and as of 2 January 2018, HMRC can no longer consider VCT advance assurance applications where the details of the potential qualifying holding are not given. The assurance does not guarantee the availability of any form of relief under the Enterprise Investment Scheme to any particular subscriber and there can be no certainty that the EIS Advance Assurance will be reconfirmed.

Investors considering taking advantage of EIS relief or making a qualifying VCT investment are recommended to seek their own professional advice in order that they may fully understand how the relief legislation may apply in their individual circumstances. Any Shareholder who is in any doubt as to his taxation position under the EIS and VCT legislation, or who is subject to tax in a jurisdiction other than the UK, should consult an appropriate professional adviser.

The Company intends to manage its working capital and balance sheet in order to optimise amounts available under the Placing for EIS/VCT investors.

The Placing

In order to broaden the Company's institutional Stockholder base and to minimise the time and transaction costs of the Placing, the New Common Stock are being placed by Panmure Gordon with only a limited number of existing and new institutional Stockholders. The New Common Stock are not being made available to the public.

Certain of the New Common Stock (the "Eligible New Common Stock") will be offered to VCTs and to those investors seeking to claim EIS relief in relation to their investment.

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 and/or Vendor Placing and/or Option Issue. Nothing in this paragraph shall exclude the liability of any person for fraudulent misrepresentation.

Registration and Settlement

Settlement of transactions in the Placing Common Stock following Admission will take place within the system administered by Euroclear UK & Ireland Limited ("CREST"), subject to certain exceptions. The Company reserves the right to require settlement for and delivery of the Placing Common Stock (or a portion thereof) to Placees in certificated form if, in Panmure Gordon's opinion, 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. Placing Common Stock acquired or held by Affiliates of the Company shall be held in certificated form and accordingly settlement shall not be permitted via CREST until such time as the relevant restrictions are no longer applicable. Affiliates of the Company at the time of the Placing, or investors that become Affiliates at any time after the Placing, should seek independent US legal counsel prior to selling or transferring any Common Stock.

Each Placee allocated Placing Common Stock in the Placing will be sent a letter enclosing a Form of Confirmation (the "Confirmation Letter") (if affirmation is not sent electronically) stating the number of Placing Common Stock to be allocated to it at the Placing Price and settlement instructions. Settlement should be through Panmure Gordon against CREST ID: 83801

For the avoidance of doubt, it is expected that Placing, Vendor Placing and Option Issue allocations will be booked with a trade date of 21 February 2019 and settlement dates of 28 Feburary 2019 and 1 March 2019, the dates of Admission.

The Company will deliver the New Common Stock and Option Stock to the CREST accounts operated by Panmure Gordon as agent for the Company and Panmure Gordon will enter its delivery (DEL) instruction into the CREST system. Stifel will deliver the Sale Stock to the CREST accounts 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 Common Stock to that Placee against payment.

It is expected that settlement will take place on 28 February 2019 in respect of the Eligible New Common Stock and 1 March 2019 in respect of the General New Common Stock and Sale Stock, on a delivery versus payment basis.

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, the Company may sell any or all of the Placing Common Stock allocated to that Placee on such Placee's behalf and retain from the proceeds, for the Company's, or Stifel's (if applicable), 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 may be required to bear any stamp duty or stamp duty reserve tax (together with any interest or penalties) which may arise upon the sale of such Placing Common Stock on such Placee's behalf.

If Placing Common Stock are to be delivered to a custodian or settlement agent, Placees should ensure that the trade confirmation is copied and delivered immediately to the relevant person within that organisation. Insofar as Placing Common Stock 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 Common Stock should, subject as provided below, be so registered free from any liability to UK stamp duty or stamp duty reserve tax. Placees will not be entitled to receive any fee or commission in connection with the Placing and/or Vendor Placing.

Notwithstanding the above, the right is reserved to deliver all of the New Common Stock and Option Stock to which the Placee is entitled in certificated form should Panmure Gordon consider this necessary or desirable.

CREST: Regulation S Category 3 Settlement Service

The Placing Common Stock has not been, and will not be, registered under the Securities Act or under any securities laws of any state or other jurisdiction of the United States. The New Common Stock and Option Stock are being offered only outside the United States in "offshore transactions" to non-US Persons as defined in and pursuant to Regulation S. The New Common Stock and Option Stock will be subject to the conditions listed under Section 903(b)(3), or Category 3, of Regulation S. The New Common Stock and Option Stock are "restricted securities" as defined in Rule 144 under the Securities Act. Purchasers of the New Common Stock or Option Stock may not offer, sell, pledge or otherwise transfer New Common Stock or Option Stock, directly or indirectly, in or into the United States or to, or for the account or benefit of, any US Person, except pursuant to a transaction meeting the requirements of Rules 901 to 905 (including the Preliminary Notes) of Regulation S, pursuant to an effective registration statement under the Securities Act or pursuant to an exemption from the registration requirements of the Securities Act.

Each subscriber for New Common Stock and the Option Stock, by subscribing for such New Common Stock or the Option Stock, agrees to reoffer or resell the Common Stock or Option Stock only pursuant to registration under the Securities Act or in accordance with the provisions of Regulation S or pursuant to another available exemption from registration, and agrees not to engage in hedging transactions with regard to such securities unless in compliance with the Securities Act. The above restrictions severely restrict purchasers of New Common Stock and the Option Stock from reselling the New Common Stock and the Option Stock in the United States or to a US Person. These restrictions may remain in place or be reintroduced following the expiry of the one-year Distribution Compliance Period in relation to the New Common Stock and the Option Stock, at the discretion of the Company, for example in the event the Company subsequently issues additional Common Stock under the same ISIN as the New Common Stock and the Option Stock. Upon the expiration of the Distribution Compliance Period, the Company may choose to merge the New Common Stock and the Option Stock into its existing unrestricted line of Common Stock.

Once the New Common Stock and the Option Stock are admitted to trading on AIM, the New Common Stock and the Option Stock will trade in the Company's new restricted line of Common Stock under the symbol MXCS, and the New Common Stock and the Option Stock (represented by the Depository Interests) subscribed for and held by non-Affiliates of the Company will be held in the CREST system and will be segregated into a separate trading system within CREST identified with the marker "REGS". The "REGS" marker indicates that the Common Stock held in the CREST system will also bear a legend setting out certain transfer restrictions and other information, including that: (i) transfers of the Common Stock are prohibited except in accordance with the provisions of Regulation S, pursuant to registration under the Securities Act or in a transaction not subject to the registration requirements of the Securities Act; and (ii) hedging transactions involving the Common Stock may not be conducted unless in compliance with the Securities Act.

Representations, warranties and certifications must be made through the CREST system by those selling or acquiring the Common Stock with the "REGS" marker. If such representations, warranties and certifications cannot be made or are not made, settlement through CREST will be rejected. Furthermore, New Common Stock and the Option Stock held by US Persons and Affiliates of the Company shall be held in certificated form and accordingly settlement shall not be permitted via CREST until such time as the relevant restrictions are no longer applicable. Affiliates of the Company at the time of the Placing, or investors that become Affiliates at any time after the Placing, should seek independent US legal counsel prior to selling or transferring any Common Stock.

Placees acquiring Sale Stock may not offer, sell, pledge or otherwise transfer Sale Stock, directly or indirectly, in or into the United States or to, or for the account or benefit of, any US Person, except pursuant to a transaction meeting the requirements of Rules 901 to 905 (including the Preliminary Notes) of Regulation S, pursuant to an effective registration statement under the Securities Act or pursuant to an exemption from the registration requirements of the Securities Act. In addition to the restricted line of Common Stock trading in the segregated trading system within CREST and identified with the marker "REGS", the Company also maintains an unrestricted line of Common Stock trading under the existing symbol MXCT. The Sale Stock will trade under the existing symbol MXCT.

Certificated Settlement

If you are not a CREST member, or if you are electing for delivery of your New Common Stock outside of the CREST system, delivery of your New Common Stock will take place in certificated form.

For non-Crest settlement on the New Common Stock, payment should be made by telegraphic transfer CHAPS or Swift so as to arrive no later than 1.00 p.m. on 22 February 2019 to the bank account provided to you in accordance with the Confirmation Letter.

Rule 144 Restrictions

The New Common Stock and Option Stock are deemed to be restricted securities under the Securities Act. Non-Affiliates of the Company purchasing New Common Stock and Option Stock will need to comply with Rule 144 promulgated under the Securities Act with respect to any resales of New Common Stock and Option Stock within the United States or to, or for the account or benefit of, US Persons on the market or otherwise until the later of (i) the first anniversary of the initial purchase of such New Common Stock and Option Stock and (ii) the expiration of the Distribution Compliance Period.

Rule 144 may be available for US resales of New Common Stock and Option Stock by Affiliates of the Company, subject to various conditions being met including, among others, the availability of current information regarding the Company, applicable holding periods and volume and manner of sale restrictions. New Common Stock and Option Stock held by Affiliates of the Company shall be held in certificated form and accordingly settlement shall not be permitted via CREST until such time as the relevant restrictions are no longer applicable. Affiliates of the Company at the time of the Placing, or investors that become Affiliates at any time after the Placing, should seek independent US legal counsel prior to selling or transferring any Common Stock. A liquid trading market for the Common Stock does not currently exist in the United States, and the Company does not expect such a market to develop soon.

Such agreement assumes, and is based on a warranty from each Placee, that neither it, nor the person specified by it for registration as holder, of Placing Common Stock is, or is acting as nominee or agent for, and that the Placing Common Stock will not be acquired by, a person who is or may be liable to stamp duty or stamp duty reserve tax under any of sections 67, 70, 93 and 96 of the Finance Act 1986 (depositary receipts and clearance services). If there are any such arrangements, or the settlement relates to any other dealing in the Placing Common Stock, additional stamp duty or stamp duty reserve tax may be payable. In that event the Placee agrees that it shall be responsible for such additional stamp duty or stamp duty reserve tax, and neither the Company nor Panmure Gordon shall be responsible for such additional stamp duty or stamp duty reserve tax. If this is the case, each Placee should seek its own advice and notify Panmure Gordon accordingly;

It further confirms that it relied on its own examination and due diligence of the Company and its associates taken as a whole, and the terms of the Placing and/or Vendor Placing and/or Option Issue, including the merits and risks involved;

45) represents and warrants that it has (a) made its own assessment and satisfied itself concerning legal, regulatory, tax, business and financial considerations in connection herewith to the extent it deems necessary; (b) had access to review publicly available information concerning the Group that it considers necessary or appropriate and sufficient in making an investment decision; (c) reviewed such information as it believes is necessary or appropriate in connection with its subscription or purchase of the Placing Common Stock; and (d) made its investment decision based upon its own judgement, due diligence and analysis and not upon any view expressed or information provided by or on behalf of Panmure Gordon or any of its affiliates;

46) understands that it may not rely on any investigation that Panmure Gordon or any person acting on its behalf may or may not have conducted with respect to the Company or the Placing and/or Vendor Placing and/or Option Issue and Panmure Gordon has not made any representation to it, express or implied, with respect to the merits of the Placing and/or Vendor Placing and/or Option Issue, the subscription for or purchase of the Placing Common Stock, or as to the condition, financial or otherwise, of the Company or as to any other matter relating thereto, and nothing herein shall be construed as a recommendation to it to subscribe for or purchase the Placing Common Stock. It acknowledges and agrees that no information has been prepared by Panmure Gordon or the Company for the purposes of this Placing and/or Vendor Placing and/or Option Issue;

47) acknowledges that all representations, warranties, acknowledgements, undertakings and agreements which have been made in this Announcement shall survive the transaction and the delivery of the Placing Common Stock; and

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 United Kingdom by them or any other person on the subscription by them of any Placing Common Stock or the agreement by them to subscribe for or purchase of any Placing Common Stock.

Each Placee and any person acting on behalf of each Placee acknowledges and agrees that either Panmure Gordon or any of the Panmure affiliates may, at their absolute discretion, agree to become a Placee in respect of some or all of the Placing Common Stock.

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 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.

References to time in this Announcement are to London time, unless otherwise stated. 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.

Panmure Gordon is authorised and regulated by the FCA in the United Kingdom and is acting exclusively for the Company and no one else in connection with the Placing and the Option Issue and Stifel in relation to the Vendor Placing, and Panmure Gordon will not be responsible to anyone (including any Placees) other than the Company or Stifel (as applicable) for providing the protections afforded to its clients or for providing advice in relation to the Placing and the Option Issue or Vendor Placing (as applicable) or any other matters referred to in this Announcement.
