The following contingent option awards were granted in the UK on 20 December
2011 to the undernoted persons discharging managerial responsibility pursuant
to the rules of the United Utilities Group 2008 Performance Share Plan as
approved by the shareholders at the General Meeting on 1 July 2008. The figures
reflect the maximum number of shares over which the option might be exercised.
The actual number will depend upon the extent to which the established
performance conditions are satisfied over the performance period. Under the
rules, the awards are subject to uplift for notional dividends made or paid
during the performance period. Accordingly, the original award is uplifted by
notional dividend shares in respect of the dividend of 20 pence per share paid
on 1st August 2011, to Messrs Dixon and Gardiner by 442 and 579 shares
respectively.
