                           Directors' shareholdings                            

The Company announces that on 26 April 2006, Mr Peter Waller, Mr Jarlath McGee
and Mr Ian Selby were granted 75,276, 602,212 and 376,382 options respectively,
over ordinary shares of 10p each ("Ordinary Shares"). For Mr McGee and Mr Selby
these replace all previously issued options, which have now been cancelled. The
options have an exercise price of 18.5p being the closing mid market price on
26 April 2006. Mr Waller, Mr McGee and Mr Selby now hold a total of 75,276,
602,212 and 376,382 options respectively.

The options have been granted under the rules of the Company's Enterprise
Management Incentive scheme, under which 25 per cent. will vest after 12 months
from the date of grant with the remainder vesting over the following three
years. Mr Waller's options will not qualify for the associated tax benefits as
he is not a full time employee.

On 26 April 2006, Ian Selby transferred 34,782 Ordinary Shares from his
personal shareholding to his Self Invested Pension Fund at 18.75p per share. Mr
Selby also purchased 10,000 Ordinary Shares on the same date at 19.28p.
Following these transactions Mr Selby is beneficially interested in 191,553
Ordinary Shares, representing 0.53 per cent. of the issued share capital of the
Company.
