This notification is made in accordance with DTR 3.1.4(1)(a).

Notice of election by executive directors to fully defer the vesting of 2012 PSP awards for two further years and the grant of conditional multiplier awards under the PSP

On 1 June 2012, Louise Makin (the CEO) and Rolf Soderstrom (the CFO) were granted Share awards under the PSP over 124,042 and 91,974 Shares respectively (the 2012 Awards). These awards were due to vest in full on 1 June 2015 based on the Company's satisfaction of the applicable 3 year stretch performance targets.

On 29 May 2015, both the CEO and CFO elected to defer the vesting and receipt of 100% of the 2012 Awards, as allowed under the amended PSP approved by shareholders at the Company's last Annual General Meeting, in order to be granted an additional multiplier award representing up to 150% of the value of the 2012 Awards which were rolled over.

In accordance with the above elections, the 2012 Awards did not vest and on 1 June 2015 the Company granted the CEO and the CFO the multiplier awards comprising 186,063 and 137,961 Shares respectively. For both the 2012 Awards and the multiplier awards to vest in full the Company's 5 year total shareholder return (TSR) to 31 March 2017 would be required to outperform the median of the TSR of the FTSE250 Index over that period by 100 percentage points. To the extent BTG underperforms the Index over that period, multiplier awards will not vest and the number of Shares the subject of the 2012 Awards which were rolled over would be reduced (potentially to zero).

The rolled over 2012 Awards and the linked multiplier awards will normally vest on 1 June 2017, subject to the CEO and CFO continuing to remain in office or employment within the group and the satisfaction of the 5 year TSR condition to 31 March 2017. Each of the 2012 Awards and the multiplier awards are structured as free share awards and the consideration for the grant of the multiplier awards was the election to rollover the 2012 Awards.
