1 Making Sugar from CO 2 BIO World Congress on Industrial Biotechnology Philadelphia Kef Kasdin, CEO May 15, 2014

We Make Sugar Proterro makes low cost sucrose that unlocks economical production of biofuels and chemicals Not Crop-Based / Not Cellulosic Avoids pricing

further processing required for fermentation to biofuels/biochemicals Easily scalable Benefits to Partners Complements 1 st and 2 nd generation ethanol

2 We Make Sugar Proterro makes low cost sucrose that unlocks economical production of biofuels and chemicals Not Crop-Based / Not Cellulosic Avoids pricing volatility Predictable, reliable source of production Much less land vs crops 1/10 water of algae systems Fermentation-Ready Drop-in sugar feedstock No further processing required for fermentation to biofuels/biochemicals Easily scalable Benefits to Partners Complements 1 st and 2 nd generation ethanol Clean sucrose (no other sugars or inhibitors for biochem) Monetizes CO 2 To supplement sugars extracted from crops or deconstructed from cellulosic materials 2

3 The Feedstock Challenge Access to a reliable, low-cost feedstock remains a critical barrier to scale for the production of bio-based fuels and chemicals. Feedstock Challenges Corn and Sugar Price Volatility: Seasonally- and market-driven price volatility Food v. Fuel: Land competition Cellulosics Biomass Availability: Access to amount of biomass required to obtain economies of scale is limited Biomass Recalcitrance and Non-Homogeneity: Fractionation and deconstruction of biomass into usable intermediates require complicated and expensive multistep processes Proterro addresses these challenges by making affordable, fermentation-ready sucrose 3
