7. Ethanol Industry Considerations 7  The ethanol industry produced approximately 14.3 billion gallons of ethanol in 2014, thereby reducing U.S. reliance on foreign oil  Helps U.S. balance of trade  Helps U.S. move towards energy independence  Over 512 million barrels of imported oil displaced  Approximately 1/3 of corn used in ethanol production is returned to feed market in the form of distiller grains, corn gluten meal and corn oil*  National benefits  Government payments to corn growers have fallen from nearly $9 billion in 2006 to less than $2 billion in 2013*  Ethanol production generates higher tax revenues  Ethanol production added over $53 billion to GDP*  Ethanol production increased household income by ~$27 billion*  $10 billion paid in federal, state and local taxes*  Industry receives no tax subsidies  Farm states are less impacted by challenged economic environment  Ethanol estimated to have supported over 379,000 jobs, including across ancillary industries, from agriculture to manufacturing to the service sector*  On a life cycle basis, corn-based ethanol reduces greenhouse gas emissions (GHGs) by ~34% compared to gasoline – 14.3 billion gallons of ethanol reduced GHG emissions by 39.6 million metric tons, the equivalent of taking 8.4 million cars off the road* Sources: Renewable Fuels Associations

14.  Much of the world’s oil reserves are in the form of heavy oil in deposits at depths below 2,000 feet  Heavy oil is too viscous to flow to the well at a reasonable rate under ordinary conditions, so technology is needed to help extract it  The most practical method developed so far is to inject steam into the reservoir, to raise the temperature thereby reducing the oil's viscosity  Current methods are limited by the heat losses on the surface and in the well bore as the steam is sent down the injection well. For any particular heavy oil reservoir and price of oil, there is a maximum depth of the reservoir that can be economically exploited 14 Deep Heavy Oil Technology Investment  REX invested in patented technology with potential to steam oil at depths currently unattainable  Current technology allows for injecting steam below grade to ~2,000 feet to extract heavy oil  New downhole steam generator technology seeks to create steam at depths below 2,000 feet to produce deep heavy oil  Modest investment / high potential returns  REX has invested ~$1.5M (through 4/30/15) for 60% equity stake in technology developer, to secure patents, and to pursue commercialization of the downhole steam generation technology  Presently seeking sites/opportunities to test and prove technology
