Renishaw plc is pleased to announce that it has conditionally agreed to invest
£6,096,208 in Delcam plc by subscribing for 1,524,052 new Ordinary Shares at
£4.00 per share.

Delcam is one of the world's leading suppliers of advanced CADCAM software
product development solutions for the manufacturing industry and is listed on
the London Stock Exchange's AIM market.

Delcam's sales for the year ending 31 December 2005 were £23.5m and its profit

It has been agreed with Delcam that Renishaw is entitled to nominate a director
for appointment to the board of Delcam for so long as Renishaw maintains a
shareholding of at least 15%.

Renishaw and Delcam have worked together for many years and share common
metrology interests and customers. Renishaw believes that closer cooperation
with Delcam will enhance the sales of both companies and will provide
opportunities for developing software to support Renishaw's products.

The Directors of Renishaw are very pleased to further their long-standing
relationship with Delcam in this manner and are confident that the new
relationship will be extremely fruitful for the progress and continuing
development of both companies.
