Each stakeholder should contact his, her or its own legal adviser, independent financial adviser or tax adviser for legal, financial or tax advice. To the extent available, the data contained in this Presentation has come from official or third party sources. Third party industry publications, studies and surveys generally state that the data contained therein have been obtained from sources believed to be reliable, but that there is no guarantee of the accuracy or completeness of such data. While Odyssey and the Company believe that each of these publications, studies and surveys has been prepared by a reputable source, the Company has not independently verified the data contained therein. In addition, certain of the data contained in this Presentation come from the Company's own internal research and estimates based on the knowledge and experience of the Company's management in the market in which the Company operates. While the Company believes that such research and estimates are reasonable and reliable, they, and their underlying methodology and assumptions, have not been verified by any independent source for accuracy or completeness and are subject to change without notice. Accordingly, undue reliance should not be placed on any of the estimates or research contained in this Presentation. Forward-looking statements. Certain information contained in this Presentation, including any information as to the Company's strategy, plans or future financial or operating performance constitutes "forward-looking statements". All statements contained in this Presentation that do not relate to matters of historical fact should be considered forward-looking statements, and these forward-looking statements can be identified by the use of terminology such as, "aims", "anticipates", "assumes", "believes", "budgets", "could", "contemplates", "continues", "estimates", "expects", "intends", "may", "plans", "predicts", "projects", "schedules", "seeks", "shall", "should", "targets", "would", "will" or, in each case, their negative or other variations or comparable terminology. Forward-looking statements appear in a number of places throughout this Presentation and include, but are not limited to, express or implied statements relating to: the Company's business strategy and outlook; the Company's future results of operations; the Company's future financial and market positions; the Company's margins, profitability,cash, borrowings and prospects; expectations as to the Company's future growth; the Company's plans with respect to capital expenditure; general economic trends and other trends in the industry in which the Company operates; the impact of laws and regulations on the Company and its operations; and the competitive environment in which the Company operates. By their nature, forward-looking statements are based upon a number of estimates and assumptions that, whilst considered reasonable by the Company are inherently subject to significant business, economic and competitive uncertainties and contingencies. Known and unknown factors could cause actual results to differ materially from those indicated, expressed or implied in such forward-looking statements. Forward-looking statements are not guarantees of future performance. Any forward-looking statements in this Presentation reflect the Company's current view with respect to future events and are subject to certain risks relating to future events and other risks, uncertainties and assumptions. The forward-looking statements contained in this Presentation reflect knowledge and information available as of the date of preparation of this Presentation. The Company and its directors expressly disclaim any obligations or undertaking to update or revise publicly any forward-looking statements, whether because of new information, future events or otherwise, unless required to do so by applicable law or regulation. Nothing in this Presentation should be construed as a profit forecast. The information contained in this Presentation is not an offer to sell or a solicitation of an offer to purchase interests in any company or a related entity, nor is it intended to provide, and should not be relied on for, investment, tax, legal or financial advice. Certain financial data included in the Presentation may consist of "non-IFRS financial measures", which may not be comparable to similarly-titled measures as presented by other companies, nor should they be considered as an alternative to the historical financial results or other indicators of the Company's cash flow based on IFRS. Even though the non-IFRS financial measures are used by management to assess the Company's financial position, financial results and liquidity and these types of measures are commonly used by investors, they have important limitations as analytical tools, and the recipients should not consider them in isolation or as a substitute for analysis of the Company's financial position or results of operations as reported under IFRS. AstraZeneca's intention to make an equity investment is an indication and not a binding agreement or commitment to purchase and therefore AstraZeneca could determine to purchase more, less or no shares, or we could determine to sell more, less or no shares to AstraZeneca. Neither this offering nor AstraZeneca's equity investment arecontingent upon one another.#3Risk Factors Any investment in Odyssey or the Company involves numerous risks and uncertainties related to the Company's business and the Proposed Transactions that may result for investors in a partial or total loss of their investment. The following is a non-exclusive selection of key risks that, alone or in combination with other events or circumstances, could have a material adverse effect on the Company's business, financial condition, results of operations and prospects as well as the Proposed Transactions. Investors should read, understand and carefully consider the risks and uncertainties described below. This summary is not comprehensive and the below key risks are subject to change. An additional discussion of the risks and uncertainties of the Company and the Proposed Transaction will be included in under the heading "Risk Factors" contained in the circular and prospectus in connection with the proposed business combination. Risks Related to the Company's Business and Industry 12 1. 2. 3. 4. 5. 6. 3456 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 2222 21. 22. 23. We have a history of significant operating losses, and we expect to incur losses over the next several years. Our operating history and business model may make it difficult for you to evaluate the success of our business to date and to assess our future viability, which may depend on us obtaining additional capital, which might not be available on economically acceptable terms, or at all. Our interim and annual results may fluctuate significantly, which could adversely impact the value of our shares. We have no products approved for commercial sale, our revenues to date have been derived from a single source and it may take several years before we generate revenue from product sales, if at all. If we and our present and future collaborators are unable to successfully develop and commercialise drug products, our revenues may be insufficient for us to achieve or maintain profitability. All of our drug candidates are in early-stage preclinical development or in clinical development. If we are unable to advance our drug candidates through clinical development, to obtain regulatory approval and ultimately to commercialise our drug candidates, or if we experience significant additional costs or significant delays in doing so, our business, financial condition, results of operations and prospects will be materially harmed. We are substantially dependent on our technology platform to identify promising drug targets to accelerate drug discovery and development. Our platform technology may fail to discover and design molecules with therapeutic potential or may not result in the discovery and development of commercially viable products for us or our collaborators. If we cannot maintain existing partnerships, including data partnerships, and/or enter into new partnerships or similar business arrangements, our business could be adversely affected. We face substantial competition, which may result in others discovering, developing or commercialising products before or more successfully than we do, requiring us to rapidly adapt our approach to significant technological change and respond to the introduction of new products and technologies to remain competitive. We contract with third parties, including, but not limited to, a number of contract research organisations ("CROS"), site providers, laboratory testing service providers, and universities for assay and experimental work for all of our drug programmes, including where applicable the manufacture of our drug candidates for preclinical development and clinical testing, and expect to continue to do so for commercialisation. This reliance on third parties increases the risk of non-performance or delay to some or all of our drug programmes, or that we will not have sufficient quantities of our drug candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialisation efforts. Because we have multiple programmes and drug candidates in our development pipeline, we may expend our limited resources to pursue a particular drug candidate and fail to capitalise on development opportunities or drug candidates that may be more profitable or for which there is a greater likelihood of success. Clinical development involves a lengthy and expensive process with uncertain outcomes. If our preclinical studies and clinical trials are not sufficient to support regulatory approval of any of our drug candidates, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development of such drug candidate. If we are unable to obtain, maintain, enforce and protect patent or other intellectual property right protection for our technology and drug candidates or if the scope of such protection obtained is not sufficiently broad, our competitors could develop and commercialise technology and products similar or identical to ours, and our ability to successfully develop and commercialise our technology and drug candidates, as well as the value of our brand and our business, may be adversely affected. Our internal information technology systems, or those of our third-party vendors (including providers of cloud-based infrastructure), contractors or consultants, may fail or suffer security breaches, loss or leakage of data and other disruptions, which could result in a material disruption of our services, compromise sensitive information related to our business, or prevent us from accessing critical information, potentially exposing us to liability or otherwise adversely affecting our business. If we fail to comply with our obligations under any our existing intellectual property licence agreements and data licensing agreements or under any future such agreements, or otherwise experience disruptions to our business relationships with our current or any future licensors, we could lose intellectual property rights (including access to data) that are important to our business. We make use of the UK's small and medium sized enterprises research and development tax relief regime, through which we have obtained cash tax credits from Her Majesty's Revenue & Customs ("HMRC"). HMRC could seek to challenge the historical cash tax credits paid, or a change of law or our circumstances could restrict our ability to claim additional such cash tax credits. Current and future healthcare and artificial intelligence legislative reform measures may have a material adverse effect on our business and results of operations. Regulatory authorities may implement additional regulations or restrictions on the development and commercialisation of our product candidates. Such changes can be difficult to predict, may require significant systems changes, divert the attention of our personnel, subject us to additional liabilities and may adversely adversely affect our business. Compliance with stringent and evolving global privacy and data security requirements could result in additional costs and liabilities to us or inhibit our ability to collect and process data globally, and the failure to comply with such requirements could subject us to significant fines and penalties, which may have a material adverse effect on our business, financial condition or results of operations. The effects of health epidemics, including the ongoing COVID-19 pandemic, in regions where we, or the third parties on which we rely, have business operations could adversely affect our business, including our preclinical studies and clinical trials, as well as the business or operations of our CROS or other third parties with whom we conduct business. Our current and future clinical trials or those of our current or future collaborators may reveal significant adverse events not seen in our preclinical or nonclinical studies and may result in a safety profile that could inhibit regulatory approval or market acceptance of any of our future drug candidates. Interim, "topline" and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data becomes available and are subject to audit or verification procedures that could result in material variations in our final data. If we experience delays or difficulties in the enrolment of patients and/or provision of medical data in clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented.

Odyssey and the Company will be subject to business uncertainties and contractual restrictions while the proposed business combination is pending. Odyssey and the Company will incur significant transaction and transition costs in connection with the proposed business combination. Odyssey's sponsor and certain of its directors and officers have interests in the proposed business combination that are different from or are in addition to other shareholders in recommending that shareholders vote in favor of approval of the proposed business combination. Odyssey's sponsor holds a significant number of shares of Odyssey's securities, and their entire investment will be lost if the proposed business combination is not completed. Odyssey's sponsor and its directors or officers or their affiliates may elect to purchase shares from public shareholders, which may influence a vote on the proposed business combination and reduce Odyssey's public float. Odyssey does not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible for Odyssey and the Company to complete the proposed business combination with which a substantial majority of Odyssey's shareholders do not agree. Warrants will become exercisable for Odyssey's ordinary shares, which would increase the number of shares eligible for future resale in the public market and result in dilution to Odyssey's shareholders. The ability of Odyssey's ordinary shareholders to exercise redemption rights with respect to a large number of shares could deplete Odyssey's trust account prior to the proposed business combination and thereby diminish the amount of working capital of the combined entity. Goldman Sachs International and J.P. Morgan AG and its or their affiliates (the "Placement Agents") are engaged in a wide range of financial services and businesses (including investment management, financing, securities trading, corporate and investment banking and research) and there may be situations where the Placement Agents and/or its or their clients either now have or may in the future have interests, or take actions, that may conflict with Odyssey's or the Company's interests. For example, the Placement Agents have in the past and may, in the ordinary course of business, engage in trading in financial products or undertake other investments for their own account or on behalf of other clients, including, but not limited to, trading in or holding long, short or derivative positions in securities, loans or other financial products of Odyssey, or other entities connected with the Proposed Transactions. Goldman Sachs International is both acting as a Placement Agent in this proposed private placement of securities and as financial advisor to the Company in connection with the proposed business combination, and a potential conflicts of interest, or a perception thereof, may arise as a result of such relationships. Odyssey has not obtained a third-party valuation or fairness opinion in determining whether or not to proceed with the proposed business combination. As Odyssey may migrate its tax residence to the UK prior to closing the proposed business combination, Odyssey may be subject to both the Luxembourg and UK corporate and tax regimes over the coming accounting periods, which could create a conflict in approach to cross-border and domestic compliance. Odyssey may be adversely affected by amendments to the corporate laws, tax laws or accounting policies of either or both of these jurisdictions, which may also have retrospective effect and be implemented unexpectedly. Future tax audits and other investigations conducted by the competent tax authorities in Luxembourg or the UK in respect of Odyssey's residence could result in the assessment of additional taxes, including corporate income taxes and withholding taxes. Odyssey's entitlement to treaty benefits under the 1967 Luxembourg-UK Double Taxation Convention (as modified by the Multilateral Instrument) (the "Treaty") may be withdrawn or the Treaty may be amended. The materialization of any of these risks could have a material adverse effect on our business, net assets, financial condition, cash flows or results of operations.
