Your Board considers that each of the resolutions detailed in the notice of AGM will promote the success of the Company and is in the best interests of the Company and its shareholders as a whole. The Directors intend to vote in favour of all resolutions in respect of their own beneficial shareholdings of ordinary shares in the Company and unanimously recommend that you do the same.

I would like to remind shareholders that, as announced on 21 March 2019, I will be stepping down as Chairman following the conclusion of this year's AGM. I would like to thank the current and past Board members for their partnership during my tenure as Chairman and take this opportunity to welcome our next Chairman, Neil Johnson. I would also like to thank you, our shareholders, for your support over the period I have served as Chairman.

Thank you for your continued support of the Company.

Yours sincerely
