Under the terms of the proposal, public shareholders of Crimson will receive 0.08288 shares of Contango for each share of Crimson they own. Based upon Contango’s closing stock price of $38.50 on April 29, 2013, Crimson shareholders would have received consideration valued at approximately $3.19 per share.
