                                 Trading Update
                                        
Radstone Technology, the world's leading independent supplier of
high-performance, embedded computer products for defence and aerospace
applications, announces today a trading update.

In our interim statement we announced that the order book for delivery in the
second half was £25.2m and that we expected that the additional sales from
orders to be both booked and shipped in the second half would exceed last year's
figure of £7.2m.

Orders booked in November and December were high at more than £16m compared to
£7m for the same period last year, but the proportion scheduled for delivery in
the second-half is less than expected. We therefore expect our second-half
bookings for delivery by year-end to be similar to last year.

Our outlook for 2007 and beyond is unchanged, supported by a growing order book
and recent design-wins on major US and European programmes.
