3. [ e x e c u t i v e s u m m a r y What is Proposed Jatrodiesel has prepared ABC Bioenergy this quotation for a 5 million gallons per year biodiesel processing facility using Jatrodiesel’s Super™ Biodiesel Processing System. The plant is designed to be co-located with ABC’s ethanol plant to process its corn oil by-product into biodiesel. However, to supplement production, the proposed system is able to simultaneously process other types of oils, even those with 100% free fatty acids (FFAs) and high sulfur content (60 ppm). Jatrodiesel knows of no other manufacturing process in commercial use that produces biodiesel at a lower production cost or with a higher quality (given the same cost of feedstock and quality). Finally, we believe we’ve provided enough detail to allow you to make a rational decision on your own; however, if you have any questions please contact us for a quick response. About Jatrodiesel’s Technology Founded in 2004, Jatrodiesel has engineered, managed construction, commissioned and supported 17 biodiesel facilities worldwide. Currently two plants are being built at existing ethanol facilities in Illinois and Nebraska. In 2011, Jatrodieselimplemented a new process into its core biodiesel system design. Called the Super™ Biodiesel Process, it overcomes the issue of processing oils with up to 100% FFA. A huge breakthrough as traditional systems can only reduce the FFAs with a maximum of 20% FFA. This opens doors for processing many more types of oils and procured usually at significantly lower costs. And regardless of oil type, they can be processed together. Also, and integral to the Super™ process, no chemical catalyst is used. By eliminating this, the one by-product of biodiesel, glycerin, does not become contaminated and yields significantly more value. Another important aspect of the Super™ System is product homogenity: that whatever feedstock is used will always look the same with a clear, water-like finish. This offers a strong marketable advantage and provided by having the final biodiesel distilled. Implementation Methodology This is not a “turn-key” project and will be managed and performed by the customer. However, Jatrodieselwill provide close support on every aspect of the plan. We believe this is the most cost-effective path for our customers to follow on such projects. Specifically, Jatrodiesel will provide all the relevant drawings (PFDs, Simulations, 3D drawings, P&IDs, etc.) including training for the implementation of the project through commissioning.

4. [ e x e c u t i v e s u m m a r y Jatrodiesel will also supply at least one vendor of various project equipment with quotes while customer is free to use these vendors or further negotiate or get additional quotes from other equipment vendors per the specifications provided by Jatrodiesel. Other Included Project Support • Once the biodiesel plant is up and running, Jatrodiesel will provide assistance training system operators. In the supply chain we will advise in the procurement for additional feedstock; identify markets; biodiesel and glycerin customers; and key vendors for chemicals and support. • Also, we will advise on all relevant information for on-going permitting including with state and local authorities; EPA reviews; and under the RFS Program, RIN reporting and compliance.

12. [ s u m m a r y Summary The project estimate provided on Page 4 of $7,536,000 includes the total all-in project cost for the process equipment, including storage tanks and labor and as further described on Page 11. However, we have estimated other additional cost, but dependent on the customer’s facilities and these estimates are on Page 4 for $2,100,450 include the costs for the land, building, building modifications/improvements, insulation, grounding, pump pads, storage containment walls, and any outside additions such as laying of a road or a rail spur. Also, Jatrodieselsuggests using a local engineer or a permitting consultant to work with the local environmental or regulatory agency (as these vary greatly by state and locality). With our prior experience in implementing similar projects in various states (MI, OH, NE, IL, NY, PA, MD, WI, and CA), we can provide guidance on the engineering, and permitting issues on the Federal level from EPA and other regulatory bodies on both process equipment and electrical/automation instrumentation requirements. Please feel free to call with any of your questions or comments. We look forward in joining you to complete this worthwhile biodiesel processing system.

13. [ a p p e n d i x A Advantages and disadvantages of Biodiesel Distillation • Advantages of Clear Solution (distillation): • Product homogeneity - whatever the feedstock, the product will always look the same • Biodiesel will look colorless (color of water -with a very faint tinge) • Excellent marketability • Superior quality for Biodiesel for both virgin and animal feedstock • Exceeds most critical ASTM standards by a significant margin • Effective against high sulfur feedstocks such as tallow, YG, poultry fat, animal fat renderings. Will reduce 60 ppm Sulfur to less than 10 ppm • Stand out in the market for providing superior product compared to others • Margins will be higher as you no additives required • All distilled product meets Biodiesel’s ASTM 6751-12 Cold Soak Filtration test. • Disadvantages of Clear Solution (distillation): • Slightly higher cost of energy • 1 to 1.5% loss of the product as a column bottom. (This product can be used as heating oil or as a boiler fuel). [ ] 13 www.jatrodiesel.com www.jatrodiesel.com
