These transactions relate to (i) transactions notified in accordance with DR 3.1.4R(1)(a) and (ii) in the case of the directors only, a disclosure made in accordance with section 324 (as extended by section 328) of the Companies Act 1985.

The share options granted are exercisable from 25^th August 2008 to 24^th August 2012, subject to the achievement of performance conditions based upon Total Shareholder Return ("TSR").

Full vesting occurs only if the TSR performance of the Company meets or exceeds the upper quartile measured against the constituents of the FTSE Global Telecoms Sector Index during the performance period starting on 1^st July 2005 and ending on 30 June 2008. Where TSR performance meets the median, one third of the initial award vests. A sliding scale operates between median and upper quartile and nothing vests for performance below the median. If performance conditions have not been met by the end of the performance period, the options lapse. Vesting must also be warranted by reference to the underlying financial performance of the Company during the performance period which will be determined by the Remuneration Committee within 12 months of the end of the performance period.

The performance shares granted will vest from 30^th June 2008 subject to the achievement of performance conditions based upon TSR. The consideration for the performance share awards is £nil.

Full vesting occurs only if the TSR performance of the Company meets or exceeds the upper quartile measured against the constituents of the FTSE Global Telecoms Sector Index during the performance period starting on 1 July 2005 and ending on 30^th June 2008. Where TSR meets the median, one third of the initial award vests. Where TSR is between median and the upper quartile the percentage of maximum number of award shares to vest will be determined on a straight line basis between 33.33% and 100%. Vesting must also be warranted by reference to the underlying financial performance of the Company over the performance period which will be determined by the Remuneration Committee within 12 months of the end of the performance period.

Until the performance share awards vest, if at all, the shares remain held by Towers Perrin Share Plan Services (GSY) Limited as Trustee of the Cable & Wireless Employee Share Ownership Trust.
