Crimson Exploration Announces Planned Reverse Stock Split.

HOUSTON -- Crimson Exploration Inc. (OTCBB:CXPI) today announced that its board of directors has approved a one for ten reverse stock split; and the Company has obtained the necessary consent of its majority shareholder to proceed with consummation of the exchange of one new share of common stock for each ten shares of old common stock. The Company filed a preliminary Schedule 14C Information Statement with the Securities and Exchange Commission today and is awaiting review, if any, of that statement before subsequent distribution of the definitive statement to shareholders of record at the close of business on July 31, 2006. Once the Schedule 14C is distributed to shareholders, and the stock split becomes effective no sooner than twenty days thereafter when the necessary state filing is made, shareholders may tender their old shares to Fidelity Transfer Company, our transfer agent, for new shares as provided for in the Information Statement. Also, once the Information Statement is distributed, the OTC Bulletin Board will issue the Company, before the stock split takes effect, a new ticker symbol under which the new shares will trade.
