Glycerin Biodiesel Vegetable Oil Catalyst Batch Production – Traditional Batch Model (1) : 40 Hr cycle (Most Biodiesel Produced This Way) Alcohol Recovery Neutralization Distillation Settler Evaporation Alcohol Water Wash Reactor Purification Evaporation Settler Mineral acid Fatty Acids In the US, soybean oil (approximately 0.1% FFA) is typical feedstock – Batch trans-esterification may handle max 0.5% FFA without acid esterification pretreatment – Conventional processes may handle max 8% FFA with acid esterification pretreatment Issues with conventional processes – Yield loss – Waste water: high volumes to clean, treat and dispose – Biodiesel quality inconsistent – Glycerin quality poor (1) National Bi odiesel Board. Conventional Biodiesel Process 8

Advantages of Nova’s Refineries Patented and proprietary refining process Continuous process yields consistent quality – Nova process 10 hours vs. conventional process of 40 hours – Does not use water wash process History of production that exceeds ASTM 6751 – Clinton: 10 MGY commercial scale facility in production since October 2006 – Sanimax: 20 MGY commercial scale facility in production since April 2007 – Scott: 20 MGY commercial scale facility in production since October 2007 (currently undergoing repairs) – Seneca: 60 MGY commercial scale facility; first 20MGY train in production since March 2008 High quality output – Very low unconverted glycerides – Low sulfur – better than ULSD – Low er carbon mass – reduces particulate emissions – Lower phosphorous, metals and sediment concentrations 97% tech-grade glycerin (clear as water) Output Process 9

Nova is a Low Cost Provider Profitable without subsidies Utilizes low cost feedstock, including high FFA animal fat: $0.35-$0.45 vs. $0.50-$0.65 per lb for soybean oil Process is insensitive to FFA levels – Accepts off spec vegetable oil and animal fats – Accepts over 25 different types of feedstock – High yield Indifferent to feedstock type, driven by pricing (1) Source: Jacobsen Commentary and Market News Bulletin May 1, 2008.
