Information to distributors

In order to comply with the product governance requirements contained in: (a) Directive 2014/65/EU of the European Parliament and of the Council on markets in financial instruments, as amended (“MiFID II”); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) national implementing measures (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 securities offered have been subject to a product approval process, which has determined that such securities 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; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the “Target Market Assessment”). Notwithstanding the Target Market Assessment, distributors should note that: the price of the Company’s shares or warrants may decline and investors could lose all or part of their investment; the Company’s shares and warrants offer no guaranteed income and no capital protection; and an investment in the Company’s shares or warrants is compatible only with investors who do not need a guaranteed income or capital protection and 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 Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Rights Issue. For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness 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 action whatsoever with respect to the Company’s shares or warrants. Each distributor is responsible for undertaking its own Target Market Assessment in respect of the Company’s shares and warrants and determining appropriate distribution channels.
