3 Presentation Overview Lignol Introduction Technology description Commercialization plans Scale up considerations Challenges & Opportunities

4 Lignol Introduction Emerging cellulosic ethanol company BC, Canada based, public company LEC:TSX-V 36 employees Offices in Burnaby, BC and Berwyn, PA $20 million in equity raised Government funding to date >$13 million $30 million of DOE funding pending for Colorado plant Promising corporate relationships, including Suncor, Weyerhaueser, Huntsman, HA International

5 Lignol’s Technology Position Lignol’s solvent-based pre-treatment technology originally developed by General Electric (GE),subsequently commercialized by Repap for pulp mill applications (Alcell) – Approximately $100 million spent commercializing technology Lignol acquired and modified the pre-treatment process for biorefinery production of cellulosic ethanol & biochemicals – Integrated proprietary process capabilities to convert the cellulose to ethanol and capture co-products e.g. Lignin ADVANTAGES: Rapidly converts cellulosic biomass into fermentable sugars with substantially lower enzyme costs Improved plant economics through valuable biochemical co-products 5

6 Lignol’s Technology High-yield ethanol production and high-value biochemicals (High Purity HP-L™ Lignin) Lignol Extraction Process Separation Enzymes & Yeast Distillation Saccharification & Fermentation ETHANOL HP-L TM LIGNIN 6 Extractives & biochemicals

7 Process Features and Benefits Process is a true biorefinery with multiple products such as CE, HP-L TM lignin and furfural +++ – Process economics enhanced by multiple revenue streams – process can be economic at smaller scale Well-proven organosolv pre-treatment process provides very clean cellulose substrate and natural, high purity lignin (HP-L TM ) – Enzymatic saccharification enhanced by clean substrate – 50% less enzyme loading, faster bioconversion – High value HP-L TM, compared with other “lignins” 7

8 Only ~60% Fermentable Components Lignol’s Pretreated Wood Substrate Dilute-Acid-Pretreated Corn Stover Steam-Exploded Wood ~95% Fermentable Components Hydrolysis is many times more effective with same enzyme dose Lignol’s “Clean” Pretreated Biomass Other leading pretreatment technologies: 8

9 Process Features and Benefits Pretreatment proven on wood-based feeds and agricultural materials – Versatile process with few feed-related limitations Co-products displace petrochemicals – Major GHG emissions reductions beyond just transportation fuel benefits Extensive demonstration and piloting facilities provide design data – Technology is “demo-ready” 9

10 Lignol’s Integrated Pilot Plant Capacity: 1 tonne per day (dry basis) – Fully integrated mini-biorefinery – 100,000 l/yr ethanol Feedstocks: Hardwood & softwood chips, agricultural residues Products: Ethanol, HP-L TM lignin, furfural, other chemicals Operation: 24/7 in campaigns Controls: Full Distributed Control Systems, 80 loops, data-logging, full lab support on-site

11 Lignol’s Integrated Pilot Plant

12 Lignol’s Demonstration Biorefinery Capacity: Nominally 100 tonnes per day (dry basis) – Fully integrated biorefinery to be built in Colorado – 10 million l/yr of ethanol Feedstocks: Local aspen and beetle-killed lodgepole pine (agricultural residues in future) Products: Ethanol, HP-L TM lignin, furfural Operation: 24/7, 300-350 days per year, start-up 2010/11 Total project cost: ~$80 million

13 Lignol’s Commercial Biorefinery Capacity: Nominally 1000 tonnes per day (dry basis) – 100 million l/yr of ethanol Feedstocks: Locally available wood and/or ag. residues Products: Ethanol, HP-L TM lignin, furfural, biochemicals Operation: 24/7, 350 days per year Total project cost: ~$300 million Location: TBA

14 Scaling up the Science Pilot plant critical to data generation Success of pilot plant critical to establishing magnitude of scale up to demonstration or commercial plant Process risk versus equipment scale up risk Step-wise process is slow and requires multiple rounds of financing Management of technology risk – Proceeding cautiously vs. urgency to get to the finish Scale up factoring 10X risk? Or 100X risk? Financial risk - $10MM, $80MM, $300MM

15 Get the basics right Ooops!

16 Scaling up the science Knowledge creation has to shift from science to engineering through appropriate stages of scale-up – Feed handling – Substantial volumes of material need to be handled – Batch versus Continuous Process – Connections between process stages, buffer storage, transportation of solids, fluids and slurries, recycle of streams, control of the process – In situ enzyme production – Separate or simultaneous hydrolysis & fermentation – VOC (Volatile Organic Compound) assessment – Proof of plant economics

17 Design considerations Feed characteristics Process optimization considerations Lignin recovery and quality Co-products

18 Process Optimization Ethanol & Biochemical yields, functionality & value Feedstock Process/equipment design Enzymology

19 Plant Location/ Variable Feed characteristics – = plant design needs to be robust and flexible Plant locations are feedstock unique: multiple species with regional variations Management of feedstock availability, seasonality, logistics Age of trees impacts relative amounts of heartwood and sapwood; sawmill chips vs. whole tree chips Biochemical output is feedstock dependent – lignin functionality is species and process condition dependent = application and value differences

20 Biochemicals – need to be accepted as value added specialty chemicals and not waste products Represent significant revenue opportunity Can substantially increase GHG reductions – to the extent that outputs can replace petroleum derivatives Quality and quantity dependent on feedstock and process conditions Additional process steps need to be developed for each bioproduct Market acceptance hurdles

21 Lignin Macro-molecule: Native lignin is a matrix polymer which the Lignol process cleaves into smaller fragments with minimal condensation preserving functionality 21 Representation of a theoretical lignin macro-molecule

22 Value proposition for HP-L TM : A unique green, renewable, sustainable GHG positive family of specialty chemicals tailored to meet specific chemical/functional application requirements Proven functional benefits in a number of polymeric systems incl PF resins Material is within generally accepted tolerances of composition and purity for industrial products = reproducibility

23 Lignol HP-L TM - color variations:

24 HP-L TM Lignin vs. other commercial lignins: PropertiesHP-L TM Kraft ligninSulphite lignin Ash<0.5%3%~2.5% Carbohydrates<1%LowUp to 50% Sulphur<0.5 ppm~ 1.6%>6% H 2 O SolubilityHydrophobicLow~ 100% Polar Solvent SolubilityVery highMedium 24

25 Applications identified for Alcell Lignin provided basis for initial application screening PF resin partial & total substitute: Oriented Strand Board (OSB) binder Molding compound Friction material green strength binder Rubber tackifiers Foundry mold binders Plywood adhesive Saturating resins - decorative laminates Other: Raw material for production of industrial grade carbon fiber Activated carbon source Feed and fuel pellet binder Soil enhancer Slow release matrix Raw material for production of aromatics Antioxidants: Rubber compounding Lubricants additives Metal working fluids, wire and tube drawing Sulphonated (water soluble) lignins: Concrete admixtures, set retardants, super- plasticizers Emulsifying agents in asphalt coating materials Dye dispersants Agricultural dispersants, surfactants Resins, Plastics & Coatings: Epoxy packaging resins -integrated circuit boards Isocyanate resin binders Photo-degradable polyethylene sheeting (agricultural mulch) Recyclable moisture-barrier paper sacks Recyclable roll wrap in printing papers Research into physiologically-active and functional additives: Poultry feed Swine feed Calf feed

26 Challenges & Opportunities Continuity of financing from lab to pilot to demonstration to commercial plants – particularly in current economic climate Opportunity to be an expert in new sustainable, renewable biochemicals – Availability of financing for development and commercialization of biochemicals – Identification of biochemical application development partners and research centers of excellence Alternatives for C5 sugar utilization
