Attractive Industry Dynamics

Ethanol Price Tracks Gasoline Price Ethanol averages more than $0.50 over unleaded (1998 Present) Page 5

Ethanol Improves Refinery Economics Ethanol valued as clean, high-octane additive Refiners able to produce suboctane blend stock (about 84 octane) Improves refinery output (2) Adding ethanol Increases octane Expands fuel Reduces emissions Ethanol viewed as a strategic blend component (1) Source: EIA, 2006, total refinery capacity has increased from 16.1 million barrels per day in 1984 to 16.9 million barrels per day in 2004 (2) Results vary by refinery, gasoline specification and market Page 6

Nationwide Blend Component 40% of US gasoline contains ethanol Ethanol expansion driven by voluntary usage MTBE has been removed in most markets RFG markets have surpassed the Midwest in ethanol use Infrastructure being built to support RFG markets Large & growing conventional blending opportunity nearby Page 7

Significant Growth Opportunity Ethanol currently represents less than 4% of the gasoline market (1) Source: RFA, September 2006 (2) Includes 2.9 billion gallons of ethanol capacity under construction (Source: RFA, September 2006) (3) Calculated as 10% of the projected 2015 gasoline market of 163.0 billion gallons (Source: EIA, 2006) (4) Calculated assuming 600 gallons of ethanol used each year per FFV and 20% mileage loss compared to conventional gasoline Page 8

Adequate Corn Supplies Expected USDA projects crop at 11.2 billion bushels this year Ethanol production accounts for 15% National Corn Growers projects 14.6 billion bushels in 2015 (1) Supports 15.9 BGY of ethanol production (1) Source: National Corn Growers and Pro Exporter, 2006; http://www.ncga.com/ethanol/pdfs/2006/howmuchethanolcan%20comefromcorn.v.2.pdf Page 9

Strong Growth Trajectory Proven operating track record 2003 2004 2005 2006 2007 2008 (1) Scheduled completion in July/August 2007 (2) Expected completion in Q1 2008 Page 12

Plants located in Low Cost Corn areas + 80 + $1.10 + 65 + 68 + 65 (1) Source for corn prices: FCStone, LLC, 2006; determined using the basis differential to the Chicago Board of Trade over a five-year period (2001 2006): Midwest $(0.15); Pacific Northwest $0.65; California $1.10; Panhandle $0.50; Gulf $0.50; Southeast $0.53. (2) Top ten corn producing states (five-year average): IA, IL, NE, MN, IN, SD, KS, WI, OH, MS; source: NASS (USDA), 2006. Page 13
