Proposed Share Consolidation

As further explained in the Notice of the AGM, one of the resolutions being proposed at the AGM will seek approval to implement a 50:1 share consolidation. Prior to the share consolidation, the Company's issued share capital totals over 9.7 billion shares, which has an impact on the trading price per share. Accordingly, it is the Directors' view that the share consolidation, on the proposed terms as set out in the Notice of AGM and below (the "Share Consolidation"), will have a positive impact on the liquidity of the shares in issue following the Share Consolidation, by reducing the number of shares in issue and raising the resultant trading price per share.

The effect of the Share Consolidation would be that shareholders holding ordinary shares of 0.001 pence each in the capital of the Company ("Existing Ordinary Shares") on the Company's register of members at 5:30 p.m. on 26 November 2021 (the "Share Consolidation Effective Date") will, on the implementation of the Share Consolidation, hold:

1 New Ordinary Share of 0.05 pence each

for every 50 Existing Ordinary Shares of 0.001 pence each

and in that proportion for any other number of Existing Ordinary Shares then held.

As further explained in the Notice of AGM, where the Share Consolidation would result in a shareholder being entitled to a fraction of a share, any such fraction shall be aggregated and the Directors will make arrangements for the resulting aggregated fractions to either be (i) sold in the market or (ii) donated to a charity at the Directors' election.

Requests will be made to the Financial Conduct Authority for the new ordinary shares to be admitted to the Premium segment of the Official List and to the London Stock Exchange and for the New Ordinary Shares to be admitted to trading on the London Stock Exchange’s Main Market for listed securities. It is expected that the current ISIN in relation to the Existing Ordinary Shares will be disabled and marked for expiry in CREST after market close on 26 November 2021 and that a new ISIN (BMG702782084) in relation to the new ordinary shares will come into effect at 8:00 a.m. GMT on 29 November 2021.
