Trading Update

The Company announces that following the notification by one of its key customers of lower than expected sales of the Company's Harpin product in the current growing season resulting in an unanticipated carry-over of inventories, the Company has reduced its expectations of sales of Harpin in 2010 and, in consequence, its expected profit before tax for the year.

The Board believes this is a onetime event and the excess inventory will be moved through the customer's existing channels by year end and deliveries of our Harpin product will realign with its expectations beginning with the 2011 marketing year. Whilst it is still early in the season and therefore difficult to forecast uptake the Board considers that it would be prudent to anticipate that the level of sales into this channel in 2010 may be 50% or more below the previously expected levels. Accordingly, whilst the Board will provide further updates as soon as possible, it is likely that it will not have much visibility on sales until the latter part of the year.

The Board believes the long term prospects for this channel remain as strong as previously expected and with potentially new markets available sales will recover to previously forecasted levels. The Board also confirms that discussions with other potential licencees for Harpin continue to progress well and remains confident of achieving further agreements during the year for application on other crops.

It is expected that the interim results will be released by early September at which time a further update will be provided as to the Board's expectations for the current year.
