12 Exploration Play-Niobrara Shale DJ Basin

13 Exploration Play--Main Fork Unit (formerly known as Christmas Meadows/Table Top Unit) A Company-estimated 2-3 TCF target project comprised of 44,000 acres and a well previously drilled but not completed in 2007 Working with a major integrated oil and gas company that has option farm-in rights where they fund forward costs through first well, including: Reprocessing prior seismic Identified preliminary development wells, pipelines and roads and initiated full field development environment impact study in 2011 Surveys and studies are being conducted in preparation for a potential 2D seismic acquisition program in 2012 or 2013 Assuming the farm-in right is exercised, Double Eagle will have a 12%-16% carried working interest after payout for a Company estimated 2-3 TCF target project
