Columbus Acquisition Corp. Announces Cancellation of Its Special Meeting of Stockholders & Termination of Integrated Drilling...

Columbus Acquisition Corp. ("Columbus") (NYSE Amex: BUS, BUS-U, BUS-WT) announced today that it has cancelled the special meeting of its stockholders to vote on the proposed amendments to Columbus's certificate of incorporation to extend the date by which Columbus must complete a business combination before it is required to liquidate (the "Extension Amendment"), which had been scheduled for 12:00 p.m., Eastern time, on Friday, May 15, 2009. Based on the proxies received from its stockholders, Columbus has determined that the Extension Amendment will not receive the votes required for approval.

Columbus is required by its certificate of incorporation to liquidate if it is unable to consummate a business combination by May 18, 2009. Because Columbus will not be able to consummate its previously announced merger with Integrated Drilling Equipment Company ("IDE") by May 18, 2009, Columbus and IDE have agreed to terminate their previously announced merger agreement.

Columbus will begin the process of liquidating and dissolving itself in accordance with its certificate of incorporation and applicable Delaware law. Columbus cannot make any assurance as to when such liquidation will be completed.
