Highest price paid per share (GBp):	2015.0000

Subject to settlement of the above purchases and cancellation of the purchased ordinary shares, the Company’s total number of ordinary shares in issue shall be 56,905,056. The Company holds no shares in treasury and therefore the total number of voting rights in the Company will be 56,905,056.
