(the "Company") in the United States or any other jurisdiction in which such offer or solicitation is not authorised or to any person to whom it is unlawful to make such offer or solicitation. The Securities may not be offered or sold in the United States absent registration or an exemption from registration under the U.S. Securities Act of 1933, as amended (the "Securities Act"). The Securities have not been, and will not be, registered in the United States under the Securities Act. There will be no public offer of securities in the United States.

In the United Kingdom, this document is being distributed to and is directed only at qualified investors, within the meaning under Article 2(e) of Regulation (EU) 2017/1129 as it forms part of English law by virtue of the European Union (Withdrawal) Act 2018 as amended, who are also (i) persons who are investment professionals within the meaning of Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (the "Order") or (ii) high net worth companies, unincorporated associations, or other persons to whom it may lawfully be communicated, falling within Article 49(2)(a) to (d) of the Order,

(all such persons together being referred to as "relevant persons"). The Securities are only available in the United Kingdom to, and any invitation, offer or agreement to purchase or otherwise acquire the Securities will be engaged in only with, the relevant persons. Any person in the United Kingdom that is not a relevant person should not act or rely on this document or any of its contents.

In any member state of the European Economic Area and in the United Kingdom (each, a "Relevant State") that has implemented the Prospectus Regulation, this document is only addressed to qualified investors in that Relevant State within the meaning of the Prospectus Regulation (also in the United Kingdom, as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018).

Solely for the purposes of the product governance requirements contained within: (a) Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; (c) local implementing measures; and (d) in respect of firms which are subject to the requirements of the U.K. Financial Conduct Authority (the "FCA") Handbook and Product Intervention and Product Governance Sourcebook, the relevant provisions of MiFID II as they form part of U.K. domestic law by virtue of the European Union (Withdrawal) Act 2018 ("EUWA") ("U.K. MiFID II"), (letters (a)-(d) together, the "MiFID II Product Governance Requirements"),and disclaiming all and any liability, whether arising in tort, contract, or otherwise, which any "manufacturer" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the pre-emptive subscription rights (the "Rights") and the new ordinary shares (the "New Shares") have been subject to a product approval process, which has determined that the New Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II. In respect of firms which are subject to U.K. MiFID II, references in this section to MiFID II shall mean the relevant provisions thereof as they form part of U.K. MiFID II; and (ii) eligible for distribution through all distribution channels as permitted by the Product Governance Rules (the "Target Market Assessment"). Any person subsequently offering, selling, or recommending the Rights and the New Shares (a "distributor") should take into consideration the manufacturer's Target Market Assessments; however, a distributor subject to the MiFID II Product Governance Requirements is responsible for undertaking its own Target Market Assessment in respect of the Rights and the New Shares (by either adopting or refining the manufacturer's Target Market Assessment) and determining appropriate distribution channels.

Notwithstanding the Target Market Assessment, distributors should note that: the price of the Rights and the New Shares (as defined in the offering materials)may decline and investors could lose all or part of their investment; the Rights and the New Shares offer no guaranteed income and are not capital protected; and an investment in the Rights and the New Shares is compatible only with investors who do not need guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to bear any losses that may result therefrom.

The Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Offer. Furthermore, it is noted that, notwithstanding the Target Market Assessment, the Sole Global Coordinator will only procure investors who meet the criteria of professional clients and eligible counterparties. For the avoidance of doubt, the Target Market Assessment does not constitute: (a) a suitability or appropriateness assessment for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other with respect to the Rights and New Shares. Each distributor is responsible for undertaking its own target market assessment in respect of the Rights and the New Shares and determining appropriate distribution channels.
