Westco Bancorp, Inc. 55th Street & Holmes Avenue 2121 South Mannheim Road Clarendon Hills, Il 60514 Westchester, IL 60154 CONTACT: Allen H. Koranda, Chairman David C.

(NASDAQ:MAFB), announced today that its Board of Directors has approved a stock repurchase plan under which the Company is authorized to repurchase up to 1,250,000 shares of its common stock. The shares to be repurchased represent approximately 5.5% of the Company's current outstanding shares. Westco Bancorp, Inc. (NASDAQ:WCBI) also announced today that its Board of Directors has approved a stock repurchase program covering 150,000 shares which represents approximately 6% of the current outstanding shares of Westco. On August 17, 1998, MAF Bancorp announced it had agreed to acquire Westco in a fixed exchange ratio transaction in which each share of Westco common stock will be exchanged for 1.395 shares of MAF common stock. As a result of the repurchase programs, the acquisition of Westco will be accounted for as a purchase transaction for financial accounting purposes, rather than as a pooling of interests as previously announced. The definitive acquisition agreement has been amended to reflect this change in accounting treatment. Using purchase accounting treatment for the acquisition, MAF will not be required to record merger-related costs and restructuring charges in the quarter in which the transaction closes as previously announced. Instead, such charges will increase the goodwill amortization expense in future periods. MAF had previously estimated that after-tax merger-related charges in the pooling of interests transaction would have been approximately $5.0 million. As amended, the transaction will be accretive to stated book value per share and modestly dilutive to tangible book value per share, assuming completion of the stock repurchase programs. MAF expects that the transaction will 3 be immediately accretive to cash earnings per share, with only nominal dilution to 1999 reported earnings per share, and that it will be accretive to reported earnings per share thereafter, in each case assuming completion of the stock repurchase programs. As of June 30, 1998, Westco Bancorp, Inc., including its wholly owned subsidiary, First Federal Savings and Loan Association of Westchester, had approximately $320 million in assets, $260 million in deposits and $50 million in stockholders' equity.
