2 Company Radiant Energy Vacuum ( REV ) Dehydration Technology Vancouver-based industrial technology company, University of British Columbia spin-off REV is a proprietary method of drying a diverse range of sensitive materials such as foods and pharmaceuticals

3 Market Position REV Advantages* Replace freeze drying (FD) as a preferred method for drying sensitive materials: Lower Cost; typically ¼ FD costs or less. Fast typical drying process about ¼ hour to 8 hours Small rapid throughput means smaller footprint in plant Continuous Flexible controllable moisture levels Improved nutrients, flavour, colour, texture and/or biological activity. Other product-specific benefits: Excellent retention of texture, nutrition, colour and flavour Puffing for piece size similar to fresh *Subject to individual product applications

4 REV Technology Technology Overview REV technology applies microwave energy under vacuum to achieve high-speed dehydration at low temperatures Designed for dehydrating sensitive materials rapidly and retaining flavor, appearance, biological activity, nutrients rehydration potential, etc. Key discoveries: 1. Methods of distributing microwave field to avoid plasma discharge in vacuum, and 2. Means of achieving reliable, homogeneous dehydration across a large load.

5 Removing moisture to preserve products Better Product Faster Process Cheaper Cost EnWave s REV Technology Superior Color, Stronger Flavor, High Nutritional Retention Minutes or Hours (1.5 hours for Blueberries) Up to 80% lower processing costs (Combination of lower capital costs, lower labor costs and lower energy costs) Freeze Drying High Nutritional Retention Hours or Days (24 36 hours for Blueberries) High capital costs, High energy costs Hot Air & Spray Drying Heat & Oxygen Damages Color, Flavor, Nutrients & Texture Hours (6 hours for Blueberries) Low capital costs, Competitive energy costs 5

6 Commercial Licenses Signed for 4 of 5 Platforms We expect REV to replace freeze drying as the industry standard for drying sensitive, high-value biological materials: Faster Smaller footprint Lower capital & operating costs Continuous Process Technology developed over 15 years and protected by 16 patents issued or pending Platforms Expanded nutrarev MIVAP powderrev quantarev (In Development) freezerev (In Development) Functionality Dehydrates pieces of solid food; continuous tumble drying High-speed, low temperature drying of purees in trays Converts bulk frozen material to dry powder; accelerated, continuous freeze drying Dries pastes, gels, liquids, or particulates; continuous highvolume belt drying above freezing High-speed continuous dehydration of biomaterials in vials 6
