PITTSBURGH (April 28, 2010) - CONSOL Energy Inc. (NYSE:CNX) (“CONSOL”) today commenced its tender offer to purchase all of the outstanding shares of the common stock of CNX Gas Corporation (“CNX Gas”) not currently owned by CONSOL for $38.25 per share in cash. CONSOL currently owns approximately 83.3% of the outstanding shares of CNX Gas common stock. The tender offer commenced today and will expire on May 26, 2010, unless the offer is extended in accordance with its terms.

As previously announced, T.

There can be no assurance that the tender offer will be completed. The tender offer is conditioned on at least a majority of the outstanding shares of CNX Gas common stock not owned by CONSOL or its affiliates (without regard to shares held by directors or officers of CONSOL or CNX Gas) being validly tendered, and not withdrawn. This condition may not be waived by CONSOL. The tender offer is also subject to other customary conditions, as specified in the offer documents. The tender offer is not subject to a financing condition. CONSOL expects to pay the offer consideration in the tender offer from its available cash.
