3. Two Multi-Billion $ Investment Spaces Agriculture Livestock Clean Water Agriculture consumes 70% of the water used in the US

4. Bion Overview • Excess nutrients recentlyacknowledged by US EPA as the greatest water quality problem in the U.S. today • Largest source in most watersheds is livestock/agriculture • Bion’s technology largely eliminates the environmental impacts of large-scale livestock production, focused on nutrients • ONLY technology that provides proven comprehensive treatment for ‘wet waste’ stream (dairy, beef cattle and swine) • Reclaims renewable energy and nutrients from the waste stream • Proven; scalable; commercially-tested; 7 US, 6 international patents ____________________________________________________________________ • New Integrated Projects • Increased scale – reduced acreage; strategic locations – reduced transportation costs; resource and operational efficiencies • Existing operations • On-site treatment with scale/central processing facilities • Substantially lower-cost alternative to publicly-funded downstream wastewater treatment

5. US Clean Water Spending • Largest cost driver: nutrient removal • Current strategy: Sector Allocation to regulated point sources and storm water – regardless of costs or efficiencies • NO LONGER SUSTAINABLE

6. Livestock: Largest Source of Excess Nutrients Traditional Manure Management Practice Nitrogen released as ammonia gas (NH4) [50%] Manure slurry Lagoon 75% N lost to the environment Manure slurry Field N Run-off [25%] Crop Uptake [25%] Aquifers Surface Waters Downstream Estuaries • Chesapeake Bay, GOM, Great Lakes, etc, etc, etc. • Hypoxia from algae/phytoplankton blooms from excess nitrogen • Pathogens, toxic blooms • Very expensive to treat water downstream now that nitrogen is diluted with millions of gallons of water

7. How Big is the Problem? • 9 million dairy cows (12 million w/ support) • 66 million swine • 100 million cattle/calves • 2 billion chickens and turkeys Nutrient load 30X to 100X human waste - UPSTREAM

8. How Bad is the Problem? US EPA now acknowledges that excess nutrients are the greatest water quality problem in the US today Increasing scrutiny of ammonia and greenhouse gas emissions, pathogens, antibiotics and hormones

9. Chesapeake Bay TMDL • Executive Order 13508 (May 12, 2009) • US EPA TMDL: first watershed-wide TMDL • Reduce 63M lbs of Nitrogen by 2025 • Six states, DC • Estimated cost (Bay-wide): • 2009: $15B to $28B • 2012: $30B to $50B • Substantial penalties for non-compliance

10. Unsustainable Cleanup Costs • $30 to $50 billion • Sector allocation strategy is obsolete/unsustainable • Non-point sources (agriculture) are low hanging fruit • Chesapeake Bay Commission/RTI Report • 50% to 90% savings through nutrient trading • Verifiednon-point source reductions fulfill mandated reduction targets • Mechanism to fund non-point source treatment • Public-Private-Partnerships (PPP) – private sector competes for public funding through an RFP that funds lowest cost solutions • Highly successful precedent: Colorado River Basin Salinity Control Project

11. PA Legislative Initiative • 2013 PA Legislative Budget and Finance Committee Report • Upstream non-point source strategy (large agriculture projects) can cut costs up to 80% of previous estimates = $1.5 billion annually • “Pennsylvania’s compliance with the CB TMDL standard is at risk as there is insufficient funding available to comply under today’s existing cost structure.” • PA Senate Bill 994 (Major Watershed Improvement Act) • Introduced June 5, 2013 • Competitive procurement program for nutrient reductions • Equal access to public funding – all solutions based on cost • 15 to 20 year off-take agreements with PA • Passed Senate Agriculture and Rural Affairs Committee June 11 • Anticipate passage of 994 or similar action in 2014

13. Annual Cost of Upstream Alternatives Source: PA LBFC Report; CB Commission Report • Bion can begin delivery of up to 2 million pounds based on full operation of Kreider 1 and 2 systems (target 2015)

14. Kreider Farms EconomicsPending PA SB 994 • Kreider 1: 2,000 dairy cows (system operating) • Kreider 1 financed by PENNVEST (PA Infrastructure Investment Authority) - $7.8 million, non-recourse, low interest, 10 yr • Anticipate Kreider 1 long-term rev agreements for 2015 • Kreider 2: 7 million chickens (target development 2014/15) • Kreider 1 & 2: ~2 million pounds annually at $8+ per pound per year when in full operation (anticipate 2015) • Anticipate $7M to $10M annual EBITDA when Kreider 1 & 2 in full operation at 2M pounds • Future Kreider expansion (Phase 3) should increase to 3 million pounds (target 2015/16)

15. Utility Revenue Model (Kreider Only) • Customer: Pennsylvania • 15 to 20 year guaranteed off-take agreements (per PA study recommendations) • Comparables P/E • York Water (YORW) 25.5 • Aqua America (WTR) 22.7 • American Water Works (AWK) 20.5 • Implied valuation of Kreider Project (20 P/E) • Phase 1 & 2 (2M pounds) $140M to $200M

16. 40 States with Livestock Waste Problem Bion has commenced discussions that may lead to installation of Bion systems on existing and/or new dairies, beef facilities and swine farms in the Midwest and/or North Central states. The most advanced discussions currently involve an initiative by Bion in Wisconsin…The Company is actively involved in discussions with various stakeholders in Wisconsin including state and local government officials and agencies, wastewater authorities and agricultural industry entities. Bion 10Q March 31, 2014 • Mississippi River Basin Healthy Watersheds Initiative • Existing unmet local phosphorus TMDLs • US EPA designates LA coastline “impaired” • First step in MRB-wide nitrogen TMDL? • Great Lakes Water Quality Agreement • Great Lakes Restoration Initiative – US • Great Lakes Nutrient Initiative – Canada • Driving phosphorus TMDLs

17. Wisconsin • Excess phosphorus impacting Lake Michigan • New phosphorus limits established in 2010 now taking effect • WI Manufacturing & Commerce estimates $4.9B to comply • Green Bay and Madison Municipal Sewer Districts facing unaffordable costs to upgrade plants and install storm water projects • WI SB 547 – Clean Waters & Healthy Economy Act adopted 4/24/14 • First state program to direct significant financial resources to long term non-point source agriculture projects, like Bion’s • Bion in discussions with WI stakeholders – regulatory, county and municipal, and point- and non-point sources – about potential large-scale projects • Wisconsin has second largest dairy herd in the US • 1,265,000 head • Large potential market for Bion

18. Market Analysis – Potential U.S. Retrofit • Thousands of farms that meet Bion’s minimum scale thresholds* • No competitors to date • Dairy • 44% of US dairy cows on farms over 1,000 head • 5,280,000 head (including support herd) • Swine • 61% of US swine on farms over 5,000 head • 40,260,000 head • Future increased regulation (or incentives) for Concentrated Animal Feeding Operations (CAFOs)? • Ammonia? • Greenhouse gases? • Pathogens? • Antibiotics? • Hormones? *Not all farms in nutrient-impaired watersheds, overwhelming majority are; illustration only

19. International Initiatives • The Company has been pursuing these opportunities [project development] within the United States during the later stages of technology redevelopment and has recently begun activities to pursue such opportunities internationally. • Bion 10Q March 31, 2013 • 540 dead zones worldwide • Nutrients focus of international concern • Livestock waste now a national security issue in China • Ed Schafer, Bion’s Exec Vice Chairman, is former US Secretary of Agriculture and former two-term Governor of North Dakota

20. Little or No Value for Technology Bion’s technology is proven and accepted but… the SECTOR – clean water spending on non-point sources – has not yet been validated • Evolving opportunity • No comparables – no research

21. Bion Technology: Highest and Best Use • New state-of-the-art, large scale, highly-efficient livestock production facilities in strategic locations, with a minimal environmental and physical footprint, that can be integrated with dedicated food processing (and in some locations biofuels production)

22. Integrated Projects Bion is presently involved in the very early development and pre-development activities related to its initial Integrated Project(s) in Pennsylvania. The Company is also involved in pre-development evaluations and discussions regarding opportunities for Integrated Projects in the Northeast, Midwest, and the North Central United States (dairy and/or beef). While all such discussions are still in preliminary stages, multiple meetings and discussions are ongoing with local and state level Pennsylvania officials related to the development of a Bion Integrated Project involving a major international livestock entity with existing operations in Pennsylvania. Additionally, the Company is involved in early stage discussions regarding development of Integrated Projects to meet specific needs of certain international markets (and regarding licensing our technology for use in overseas locations). Bion 10Q March 31, 2014 If an Integrated Project with a major ag player moves forward it will validate Bion’s technology as an economic solution, not dependent on regulatory mandate
