SET FORTH BELOW IS A MEMORANDUM TO EMPLOYEES OF MANUFACTURERS BANK AND OTHER MATERIAL REGARDING THE PLANNED MERGER OF MB FINANCIAL, THE PARENT COMPANY OF MANUFACTURERS BANK, AND MIDCITY FINANCIAL. THE MEMORANDUM AND THE OTHER MATERIAL HAVE BEEN POSTED ON MB FINANCIAL'S INTRANET FOR EMPLOYEES. TO: All Manufacturers Bank Employees FROM: Mitchell Feiger DATE: April 20, 2001 I am very pleased to announce that MB Financial, Inc., the parent company of Manufacturers Bank, plans to merge with MidCity Financial Corporation. The combination of our two quality organizations will create a new, even more powerful banking and financial services company with assets exceeding $3 billion. As a result, we will become the third largest independent commercial banking company based in Chicago and the largest independent bank in the area focused on serving middle market businesses. Together, we will have 39 branches, 32 of them located in the Chicago area. The merger marries two organizations with similar philosophies and customer bases. We both share a commitment to our neighborhoods and the entrepreneurial business community. The combination of our two organizations, in fact, brings us even closer to realizing our goal of becoming the area's premier middle market bank. By combining a company with strong asset generation (Manufacturers), and a company with strong internal funding sources (MidCity), we will position ourselves for exceptional growth in the future. This will enhance your opportunities for career development and create increased shareholder value. All of our customers will benefit from a greater breadth and depth of services as well as the convenience of an expanded branch network. Upon completion of the transaction, MB Financial will remain our holding company name. We plan to combine MidCity's three Chicago area banks (Mid-City National Bank of Chicago, First National Bank of Morton Grove and First National Bank of Elmhurst) with Manufacturers Bank to create a single $3 billion bank with 32 offices. MidCity's Texas and Oklahoma banks, Abrams Centre National Bank and Union Bank and Trust Company, will retain their names and status as independent banks. The name of the Chicago area bank will be determined prior to the completion of the merger. We expect the merger to be completed before the end of the year. The combination of our organizations will result in significant change. I recognize that with change comes some uncertainty. As you know, one of our core values is open communications and we fully expect to live up to that value throughout this process. We will continue to share information with you on a regular basis and we will establish a communications vehicle to answer your individual questions. In the meantime, I encourage you to review the Frequently Asked Questions (FAQ) document, which has been posted on the Intranet along with the Press Release and Investor Presentation announcing the merger. This merger presents a terrific opportunity for employees, customers and shareholders. I am confident that with your help, we'll have a smooth transition. Together, we'll get it done.
