    • Deployment of Third- Generation Cellulosic Biorefineries Tim Eggeman, Ph.D., P.E. TAPPI International Bioenergy & Bioproducts Conference Memphis, TN October 16th, 2009
    • Company History • Incorporated in 2002 • Series A ($6MM) in 2006 – Led by Mohr Davidow Ventures (MDV) and Firelake Capital Management – Proved out technology at lab scale • Series B ($34MM) in 2008 – Co-led by Globespan Capital Partners and PrairieGold Venture Partners, follow on from Series A VCs – Valero Energy Corporation – Money raised for Demo plant • Current Status = Execution on Demo Plant 2
    • CONFIDENTIAL ZeaChem Technology • “Third-generation” ― Best of bio & thermo chemical processes ― Hybrid cellulosic technology – “Prius” BioChemical ― Highest theoretical yield 160 gal/BDT • Proven components & processes ― Natural organism; no enzymes ― Ultra-low CO2 net impact • Product platform flexibility ThermoChemical ― Biofuels (ethanol, butanol) ― Biochemicals (ethyl acetate, propylene) 3
    • ZeaChem Technology ZeaChem’s Core Technology Sales Sugar Acetic Solution Acid Ethyl Biomass: Acetate • Hardwood • Softwood • Switch Grass Ethanol • Corn Stover Sales Hydrogen Residue to Gasifier 4
    • Theoretical Yields Biochemical Only Thermochemical Only Syngas Fermentation ZeaChem Hybrid Yield: 78-112 gal(neat)/BDT Yield: 112 gal(neat)/BDT Yield: 112 gal(neat)/BDT Yield: 156 gal(neat)/BDT 39-56 56 56 78 Balance 4 Balance Mixed Alcohol Balance Biochemical Hydrogenolysis 14 Synthesis 14 Processing Balance 18 Biochemical Balance Syngas Syngas H2 Ester Processing 61-44 70 70 52 30 Balance Residue Balance Thermochemical 30 Thermochemical Biochemical 8 Thermochemical 30 Processing Processing Processing Processing 100 100 100 60 40 Other, 10 Cellulose, 40 100 Lignin, 30 Hemicellulose Values in Italics Indicate Chemical Energy Acetate, 2 Hemicellulose Flow Normalized to Biomass = 100 Sugars, 18 Yield assumes 200 gal(neat)/BDT for 100% Chemical Efficiency

    • ZeaChem Pilot Plant 7
    • Fermentation Data 70 Exceeds Target 60 Titer in 60 Hours 50 Target Titer = 50 g/l Acetic Acid, g/l 40 Fermentation Works Well With Hydrolyzates. 30 Mixed Sugars, Wood Breakdown Products, etc. Issues Are Solved. 20 Corn Syrup 10 Poplar Hydrolyzate 0 0 50 100 150 Time, Hr
    • A Resource That Lasts Forever™ About GreenWood Resources 9
    • Feedstock Strategy • ZeaChem process is feedstock agnostic – Hardwood, softwood, grasses, corn stover, etc. • Dedicated sustainable energy crops – Geographic diversity, “Grow where we go” • Contract with GreenWood Resources – Supply high yield hybrid poplar feedstock • Benefits – Efficient harvesting, cost effective – “Store on the stump” – Integrate energy crop + biorefinery = minimal footprint, low CO2 10
    • Efficient Harvesting 11
    • Maximizing Land Productivity ⎛ Land ⎞ ⎛ Farm ⎞ ⎛ Factory ⎞ ⎛ Auto ⎞ ⎜ ⎟ ⎜ ⎟ ⎜ ⎟ ⎜ ⎟ ⎜ Productivity, ⎟ = ⎜ Yield, ⎟ x ⎜ Yield, ⎟ x ⎜ Efficiency, ⎟ ⎜ miles/ac/yr ⎟ ⎜ BDT/ac/yr ⎟ ⎜ gal/BDT ⎟ ⎜ miles/gal ⎟ ⎝ ⎠ ⎝ ⎠ ⎝ ⎠ ⎝ ⎠

    • ZeaChem Carbon Advantage Fuel Technology GHG % Reduction from Gasoline Gasoline 0% Corn Ethanol 21-24% Cellulosic Ethanol w/Stover 86-89% ZeaChem w/Energy Farm 94-98% 14
    • Advancing Biofuels and Biochemicals Markets C2 Chain C3 Chain Ethanol Ethylenes Propylene & Propylene Glycol Acrylics (consumer product additive) • Start with C2 chain: ethanol, ethyl acetate • Expand to C3 chain – and beyond – Dramatically increases market scope – Hedge against market volatility 15
    • Deployment of Demo Plant • Construction begins in 2009, Operation begins in 2010 • Hybrid poplar + others feedstocks • 75 Construction jobs, 25 Operating jobs • Next Steps: – Scale to 1st Commercial Plant – Retrofits to pulp mills and corn ethanol plants 16
    • Partnerships • Strategic Partners • Feedstock • VC Investors • Research 17
    • • Multi-stakeholder organization to develop comprehensive voluntary sustainability standards for the production of biomass and its conversion to bioenergy – Feedstock developers and producers, Environmental NGOs, Biorefinery developers, Petroleum industry • Sustainability categories include: – Biological diversity, Climate change, Integrated Resource Management planning, Socio-economic well-being, Soil quality, Water quality and quantity • Will recognize existing sustainability standards including Forest Stewardship Council (FSC), Sustainable Forestry Initiative (SFI), and Program for the Endorsement of Forest Certification (PEFC) • Draft standard open for public review and comments through November 9th www.csbp.org 18
    • ZeaChem Summary • Highest yield, best of biochemical and thermochemical • Proven technology, naturally occurring organism • Dedicated sustainable energy crops • Product flexibility: biofuels and biochemicals • Deploying at demo plant scale 19
