trading on the London Stock Exchange on 7 July 2011, to the undernoted
directors and persons discharging managerial responsibility in exchange for
full market value. These shares will constitute `investment shares' as defined
in the rules of the United Utilities Group PLC 2008 Matching Share Award Plan
(the `Plan') which was approved by the shareholders at the general meeting on 1
