IMDEX LIMITED — Investor Presentation 2008

Dear Sir/Madam

Conference Presentation

Attached is a copy of the presentation being made at the Commsec Mining Services Conference and the Patersons Go West Conference this week.

Shareholders will recall that in January 2008, Imdex acquired System Entwicklungs GmbH (SEG). SEG has world class down hole instrumentation technology, in particular, the "Target INS system", which is being used in the oil and gas industry. Initial financial modelling for FY08 undertaken by Imdex at the time was based on existing orders for the sale of Target INS systems. However, as with other down hole technology owned by Imdex, Imdex favours the rental model rather than the sale model and that marketing model has since been largely accepted by customers of Imdex.

In changing the marketing model for the SEG product, revenue and profit in the current year will be less than the published forecast by the Company.

The strategy of pursuing rentals rather than sales builds a more profitable and sustainable business in the medium to long term. This transition has had the effect of reducing forecast revenue and profit in the current year. Consequently, your attention is drawn to Slides 11 and 13 where FY08 revenue and EBITA forecasts are revised downwards by 3% and 7.5% respectively.

Robust trading conditions prevail and global demand remains strong in both drilling fluids and down hole instrumentation.

Yours sincerely Imdex Limited
