CHICAGO -- MB Financial, Inc. (NASDAQ Global Select: MBFI), today announced that MB Financial Capital Trust I (NASDAQ Global Select: MBFIP, CUSIP 57887Q 20 9) will redeem all $59.8 million aggregate liquidation amount of its outstanding 8.60% Cumulative Trust Preferred Securities on October 2, 2007, at a redemption price per security equal to the $25.00 liquidation amount per security plus accrued and unpaid distributions to the redemption date. Distributions will cease to accrue on the trust preferred securities effective on the redemption date.

The additional trust preferred securities include $30 million in trust preferred securities issued on September 20, 2007 in a private transaction placed by FTN Financial Capital Markets and Keefe, Bruyette &Woods, Inc. exempt from registration under the Securities Act of 1933, as amended. These newly issued securities bear interest at the rate of three-month Libor plus 1.30%.
