CONSOL Energy Inc. (“CONSOL Energy”) and certain of its subsidiaries, including Consolidation Coal Company (“CCC”), Island Creek Coal Company (“ICCC”) and CNX Gas Company LLC (“CNX Gas”) (collectively, “CONSOL Energy”), have entered into a Settlement Agreement dated May 31, 2010 with Yukon Pocahontas Coal Company, Buchanan Coal Company and Sayers-Pocahontas Coal Company (the “Yukon Parties”) to resolve litigation pending in the Circuit Court of Buchanan County, Virginia, and all related legal and environmental proceedings, including several arbitration proceedings. The lawsuit related to CCC’s deposit of untreated water from its Buchanan Mine into the void spaces of nearby mines of ICCC. The Yukon Parties were seeking to stop CCC from depositing any additional water in these areas, to require CCC to remove the water that is stored there along with any remaining impurities, to recover over $3.25 billion for alleged damages to the coal and gas estates and punitive damages in the amount of $350,000. The Yukon Parties also asserted damage claims of $150 million against CONSOL Energy, CNX Gas and ICCC.

Under the Settlement Agreement, CONSOL Energy will pay the Yukon Parties (i) $25 million in damages associated with the litigation; (ii) $30 million to purchase certain of the Yukon Parties’ coal interests in the Pocahontas No. 3 coal seam, and rights appurtenant thereto, near the Buchanan Mine, believed to include approximately 21.6 million net tons; and (iii) $20 million in advance royalties on the remaining Pocahontas No. 3 coal owned by the Yukon Parties and leased to ICCC and which CCC intends to mine as part of the Buchanan Mine in the future, provided, that this payment will be recoupable against future royalties only after $20 million in future production royalties has been paid to the Yukon Parties on the production of such coal.

The Settlement Agreement includes a release by the Yukon Parties of all claims against CONSOL Energy arising out of the deposit of water in the mine voids at issue in the litigation and other customary terms. The Settlement Agreement also requires the Yukon Parties to withdraw their pending objection’s to CCC’s permit to discharge water from the Buchanan Mine into the Levisa River.

The settlement is expected to close by June 10, 2010.

CONSOL Energy must perform an evaluation of the coal interests being acquired and the advance royalty being paid before it can determine definitively the income statement impact of the settlement.
