Demand/Pricing Drivers Ethanol  Federal EPA ethanol purchasing mandates continue to rise, requiring refiners to purchase more ethanol each year: YearTarget BGY BGY BGY BGY 2015 & beyond15.0 BGY  $0.45 per gallon VEETC (blender’s credit) expires Dec. 31, 2011 Distillers Grain  Rising corn prices have driven DDG pricing increases, helping offset impact on crush spreads 7

Crush Spread & DDG Pricing  Crush Spread = price of 1 gallon of ethanol - cost of corn to produce it  One bushel of corn makes ~2.8 gallons of ethanol  Crush spread = Ethanol price – (Corn bushel price / 2.8)  Crush spread excludes other production, transportation costs, etc.  Dried distillers grain (DDG) pricing has offset weaker crush spreads  REX’s average realized DDG prices per quarter are reflected on green line below.
