Midwest Receives Second Request Under HSR Act

MILWAUKEE, Oct. 4 /PRNewswire-FirstCall/ — Midwest Air Group, Inc. (AMEX:MEH) , parent company of Midwest Airlines, announced today that it has received a request for additional information, commonly referred to as a Second Request, from the U.S. Department of Justice (DOJ) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (HSR Act) with respect to the previously announced merger agreement that provides for the acquisition of Midwest by an affiliate of TPG Capital, L.P. The effect of the Second Request is to extend the waiting period imposed by the HSR Act up to 30 days after Midwest has substantially complied with the Second Request, unless that period is extended voluntarily by Midwest or terminated sooner by the DOJ.

Midwest intends to respond expeditiously to the Second Request and to work toward a prompt closing of the transaction. In addition to the expiration of the waiting period under the HSR Act, completion of the transaction remains subject to approval by Midwest’s shareholders and satisfaction of other customary closing conditions.

Midwest has previously announced that a special meeting of shareholders will be held at 10 a.m. Central time on Tuesday, October 30, 2007, at the Wyndham Milwaukee Airport Hotel (formerly the Four Points by Sheraton), 4747 S. Howell Ave., Milwaukee, Wis. At the meeting, shareholders will vote on the proposal to approve the Agreement and Plan of Merger, dated as of August 16, 2007, by and among Midwest, Midwest Air Partners, LLC, and Midwest Acquisition Company, Inc. Midwest anticipates no change to the timing of this meeting as a result of the Second Request and encourages shareholders to vote as soon as possible, if they have not already done so.
