MB Financial Bank Acquires Deposits and Loans of InBank

Mitchell Feiger, president and CEO of MB Financial, Inc. (NASDAQ: MBFI) announced that MBFI’s subsidiary, Chicago-based MB Financial Bank, N.A., acquired the deposits and loans of Oak Forest-based InBank at the close of business today in a transaction facilitated by the Federal Deposit Insurance Corporation (FDIC).

"Our top priority is to assure customers that their deposits are safe and remain readily available to them,” says Feiger. "MB Financial Bank has a healthy balance sheet and a strong capital and liquidity position. We’ve been part of Chicago-area banking for nearly 100 years earning a reputation for quality customer service and sophisticated banking products and services. This agreement with the FDIC provides a safe and secure home at MB for InBank customers.”

The three branches of InBank will reopen as MB Financial Bank on their next normally scheduled business day; Oak Forest and Tinley Park will reopen on Saturday morning, Sept. 5, 2009 and the Chicago branch on September 8, 2009. Customers of InBank should continue to bank as usual.

"Once we consolidate InBank and MB computer operating networks, all customers will have access to over 70 locations; our Telephone Banking Center, which is open seven days a week; our Internet Banking systems and our ATM network,” adds Feiger. "MB looks forward to serving the banking needs of InBank customers.”

As of August 3, 2009, InBank had total assets of approximately $212 million and total deposits of approximately $200 million. MB will assume all the deposits of InBank, except approximately $50.0 million of brokered accounts. The FDIC will pay the brokers directly for these accounts. In addition, MB agreed to purchase essentially all of the assets of InBank.
