Harris Announces Expansion into Wisconsin
Two acquisitions add 40 full-service locations and move Harris closer to goal of 350-400 U.S. branches

CHICAGO, July 10, 2007 – Harris and its parent company, BMO Financial Group (TSX, NYSE: BMO), today announced they are expanding the U.S. Personal and Commercial Banking business with the definitive agreements to acquire two Wisconsin banks in a move that will increase the Harris branch network by nearly 20 percent.

In two separate transactions, BMO and Harris announced the acquisitions of Ozaukee Bank and Merchants and Manufacturers Bancorporation, Inc. Combined, the two banks have approximately 40 full service locations – more than 20 in the Milwaukee area - and 13 limited service locations, as well as over US$2 billion in assets and US$1.7 billion in deposits.

"Today's announcements will move us further toward our goal of becoming the leading Personal and Commercial bank in the U.S. Midwest," said Bill Downe, Chief Executive Officer, BMO Financial Group. "These acquisitions will allow us to enhance the experience the customers of these banks already have by adding the full breadth of personal, business and wealth management services that Harris has delivered in the Chicago market for 125 years."

Harris and BMO announced a definitive agreement for BMO to purchase Ozaukee Bank in a stock transaction valued at US$190 million. Under the agreement, Ozaukee Bank holders will receive approximately 3 million shares of BMO Financial Group (Bank of Montreal). The exact number of shares will be determined based on a formula prior to closing. Ozaukee Bank is a community bank with six full-service and two limited-service locations in the northern part of the greater Milwaukee area. With US$694 million in assets and US$561 million in deposits, Ozaukee Bank is the deposit share leader in its market.

Additionally, Harris and BMO announced a definitive agreement to purchase Merchants and Manufacturers (OTC: MMBI), also headquartered in the Milwaukee area, for US$137.2 million in cash, or US$37.30 per share of Merchants and Manufacturers common stock. Merchants and Manufacturers is a multi-bank holding company with six bank subsidiaries operating 34 full-service and 11 limited-service locations in an area concentrated in Milwaukee, and extending into Green Bay to the north and LaCrosse to the west. Me rchants and Manufacturers’ banks have a combined US$1.5 billion in assets and US$1.2 billion in deposits, holding more than half of their deposits in the Milwaukee area.

"Milwaukee is an attractive market for Harris for two important reasons. First, its size and proximity to Chicago - less than 100 miles separate the two cities - make it a natural fit for us. Second, Milwaukee is a relatively affluent market with median household income and projected household income growth higher than the national average," said Ellen Costello, Chief Executive Officer, Harris Bankcorp, Inc. "When you add to that the commitment to customer service and community involvement Harris shares with these banks, we believe we have significant potential to grow our market share even further."

The combined transactions represent a price-to-book multiple of 2.2 times book, consistent with purchase multiples in the U.S. Midwest. Excluding one-time costs, the transactions are mildly dilutive to cash earnings per share in year one and mildly accretive to cash earnings per share in year two.

Both acquisitions are expected to close later this year pending approval by U.S. and Canadian regulators, as well as shareholders of the respective companies.

Following the acquisition of First National Bank & Trust in central Indiana, which was completed this year, Harris N.A. has more than 230 locations and over 580 Harris-branded ATMs in Illinois and Indiana. The Wisconsin acquisitions move Harris closer to its goal of 350 to 400 locations across the Midwest. With $42 billion in assets and $29 billion in deposits, Harris is the second-largest bank based on branches in the Chicago market. Additionally, Harris has affiliated wealth management offices in Arizona, California, Florida, Georgia, Virginia and Washington.

"Our central Indiana transaction showed just how effective we are in bringing acquired companies on board in an efficient and cost-effective way, because we place su ch high value on the customers, the market presence and the expertise of the people we gain," Costello said. "Our determined approach and the strong partnership we forge with leaders in the acquired companies are critical to our success."
