Caledonia Investments plc ('Caledonia') is pleased to announce that it has
acquired a 22% stake in Satellite Information Services (Holdings) Limited

coverage of UK and international horseracing, greyhound and other betting events
which it packages in a suite of dedicated services and distributes to over 9,000
licensed betting offices in the UK and Ireland.  In other areas SIS provides
media distribution and production services to a number of domestic and
international clients that include three of the UK's largest news broadcasters.

Other investors in the company include William Hill, Hilton Group, United
Business Media, the Racecourse Association and the Tote.

John May, a director of Caledonia, will be joining the SIS board.

Commenting on the acquisition of the stake, Tim Ingram, Chief Executive of
Caledonia, said:

'SIS is a well established and successful business. It has a pivotal role to
play in the provision of content and data to the betting industry as well as
developing other distribution and production services to media and broadcasting
clients.  We have been very impressed with the achievements of the management
team and feel Caledonia's long-term investment approach is well suited to
supporting them in their future development.'
