Trading update

Consistent with the momentum highlighted at the time of our final results for the year to 30th June 2010, trading in the first two months of the new financial year has been very positive. We have seen strong demand for our metrology products across all our main geographies, particularly in Japan and the rest of Asia, where sales have been running at approximately double last year's levels for the same period. Group revenue in July and August has been approximately £20 million per month and the order book currently stands at approximately £25 million. Order visibility remains at around 4 to 5 weeks' sales.

A further update on trading in the first quarter will be provided in our Interim Management Statement timed to coincide with our AGM on 14th October 2010.
