Econmics Assumptions based on 5 tonne/hr machine processing 36, 000 tonnes per annum. Feed Material is Meal with 18% Oil, 5% water Operating Cost to extract Oil: 21 €/Te (feed) Income from recovered Oil: 36 €/Te (feed) Profit 15 €/Te (feed) Profit per annum 540, 000 €/p. a. Capital Cost 1, 500, 000 € Confidential 9

Summary Process Advantages Employs highly efficient electromagnetic heating methods – minimising energy usage Treating meal with non-contact microwaves and rupturing cells to maximum oil yield Microwave allows high internal temperatures but LOW bulk temperatures Providing a very flexible and controllable continuous thermal process – electromagnetic energy is instantly responsive to the control system – no thermal degradation of oil Occupies a very small foot print – the central processor is smaller than a 40 foot container Low operating cost with less than 3 year capital payback Confidential 10
