Cavendish Capital Markets Limited ("Cavendish") acted as nominated adviser, broker and bookrunner in respect of the Placing.

The Placing Shares and Subscription Shares represent, in aggregate, 39.5 per cent. of the Company's Existing Ordinary Shares.

The Placing and the issue of the New Shares are conditional upon, amongst other things:

• the passing of the Resolutions without amendment to be proposed at the General Meeting; and
• the Placing Agreement having become unconditional (save for Admission) and not having been terminated in accordance with its terms prior to First Admission and/or Second Admission, as appropriate).
