2. Overview The Vision Pipeline & Platform Brazil: Proof of Concept Going Global What’s Next 2

3. NexSteppe Vision Be a leading provider of scalable, reliable and sustainable feedstock solutions for the biofuels, biopower and biobased product industries 3

4. The Big Picture Biobased Products & Advanced Biofuels Sweet Sorghum Fermentable Sugars Biomass Sorghum Biomass Biopower & Cellulosic Biofuels

5. Why a Dedicated Crop? Reliable, scalable supply Production cost, not volatile market price Reduced acreage requirement Better biomass quality 5 Collection Radius for 500K tons 4 tons/hectare 25 tons/ hectare 38 km15 km

6. Why Sorghum? For the grower… – High-yielding – Harvest in 3-4 months – Can be rotated with other crops – Established agronomic systems For the processor/project developer… – Drop-in – Broad geographic adaptation – Heat and drought tolerant For the seed company… – Huge genetic diversity – Rapid breeding and product development cycle – Fast scale-up – Established hybrid systems – Seed propagated 6

7. The Pipeline 7 >15,000 lines screened; hundreds of breeding populations created >4000 lines selected from breeding populations and in development >2,500 hybrids in screening trials >100 hybrids in registration 18 hybrids commercialized

8. Our Technology Platform Germplasm & Breeding Chemistry & Composition Unique knowledge of impact of composition on downstream processing and resulting ability to develop process-optimized products Industry leading diversity and quality of germplasm collection Proprietary data management system linking information and providing insight to breeding program World-class marker- assisted breeding program to enhance product improvement efficiency Agronomy NexSys Focus on developing optimized crop management practices Genetic Markers 8

9. Energy Demand Is Increasing And Hydro Is Not Keeping Up 9 Biomass and fossil fuels are making up the difference Bkwh

10. Biomass Power in Brazil 12GW installed biomass power capacity, projected to double by 2021 170 of 389 mills now connected to the grid; plus >300 additional biomass plants At grid-connected mills, electricity is providing a large share of profits Biomass prices rising with increasing demand 10

11. Palo Alto Biomass Sorghum 11  Annual biomass crop  Reaches maturity in ~120 days  High yield  Low moisture at harvest  High lignocellulosic content
