Information to Distributors

Solely for the purposes of the product governance requirements of Chapter 3 of the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK Product Governance Requirements) may otherwise have with respect thereto, the Offer Shares and the Offer Warrants subject of the Offering have been subject to a product approval process, which has determined that: (a) the target market is eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook, and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of UK law by virtue of the European Union (Withdrawal) Act 2018, as amended and supplemented; and (b) all channels for distribution to eligible counterparties and professional clients are appropriate (the "UK Target Market Assessment").

Any person subsequently offering, selling or recommending the Offer Shares and Offer Warrants (a "Distributor") should take into consideration the manufacturers' relevant UK Target Market Assessment; however, a Distributor subject to the UK Product Governance Requirements is responsible for undertaking its own target market assessment in respect of the Offer Shares and the Offer Warrants (by either adopting or refining the manufacturers' UK Target Market Assessment) and determining appropriate distribution channels.

Notwithstanding the UK Target Market Assessment, Distributors should note that: the price of the Offer Shares and Offer Warrants may decline and investors could lose all or part of their investment; the Offer Shares and Offer Warrants offer no guaranteed income and no capital protection; and an investment in the Offer Shares and Offer Warrants is compatible only with investors who do not need a 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 be able to bear any losses that may result therefrom. The UK Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Offering.

For the avoidance of doubt, the UK Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of Chapters 9A or 10A of COBS; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Offer Shares and Offer Warrants.

Each Distributor is responsible for undertaking its own target market assessment in respect of the Offer Shares and Offer Warrants and determining appropriate distribution channels.

Prohibition of sales to UK, EEA and Swiss Retail Investors

The Offer Warrants and Offer Shares are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom, EEA or in Switzerland, in or as part of the Offering. For these purposes, (A) in the United Kingdom a "retail investor" means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of UK law by virtue of the European Union (Withdrawal) Act 2018 (as amended, the "EUWA"); or (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, the "FSMA") and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97 (as amended, the "Insurance Distribution Directive"), where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of UK law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 (as amended, the "Prospectus Regulation") as it forms part of UK law by virtue of the EUWA; (B) in the EEA, a "retail investor" means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, "MiFID II"); or (ii) a customer within the meaning of the Insurance Distribution Directive, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation; and (C) in Switzerland, a "retail investor" means a person who is not a professional client as defined in Article 4 Paragraph 3 of the Swiss Federal Act on Financial Services (the "FinSA"). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the "PRIIPs Regulation"), including the PRIIPs Regulation as it forms part of UK domestic law by virtue of the EUWA (the "UK PRIIPs Regulation") for offering or selling the Offer Warrants and Offer Shares or otherwise making them available to retail investors in the UK, EEA or in Switzerland has been prepared and, therefore, offering or selling the Offer Warrants and Offer Shares or otherwise making them available to any retail investor in the UK, EEA or in Switzerland may be unlawful under the UK PRIIPs Regulation, the PRIIPs Regulation or the FinSA, as applicable.
