News Release First Midwest Bancorp [FIRST MIDWEST BANCORP, INC. LOGO GOES HERE] 300 Park Blvd., Suite 405 P.O. Box 459 Itasca, Illinois 60143-9768 (630) 875-7450 FOR IMMEDIATE RELEASE CONTACT: James M. Roolf 630/875-7452 TRADED: NASDAQ/NMS SYMBOLS: FMBI HERS FIRST MIDWEST BANCORP TO ACQUIRE HERITAGE FINANCIAL SERVICES ITASCA, IL., JANUARY 15, 1998 -- First Midwest Bancorp, Inc. (NASDAQ:FMBI) and Heritage Financial Services, Inc. (NASDAQ:HERS) today jointly announced that they have entered into a definitive agreement whereby First Midwest will acquire Heritage, a $1.3 billion holding company headquartered in southwest suburban Chicago's Tinley Park, Illinois. The combined company will have assets of approximately $5.0 billion, deposits of nearly $4.0 billion, shareholders' equity of $450 million and a market capitalization exceeding $1.3 billion. The agreement provides that Heritage's shareholders will receive .7695 shares of First Midwest common stock for each share of Heritage common stock resulting in the issuance of approximately 9.7 million First Midwest shares. Based on First Midwest's January 14 closing price of $42.38 per share, the transaction is valued at approximately $411 million. The transaction will be structured as a tax-free share exchange and accounted for as a pooling of interests. In connection with the agreement, Heritage has granted First Midwest an option to purchase 19.9% of its common stock under certain circumstances. The agreement has been approved by the Board of Directors of both First Midwest and Heritage. Following receipt of shareholder and customary regulatory approvals, the acquisition is expected to close in the second quarter. After closing, three Directors of Heritage will join the current 11 member Board of Directors of First Midwest. Based upon projected savings only, the transaction is expected to be approximately 3.5% dilutive to 1998 earnings and accretive to 1999 earnings. Cost savings approximating 30% of Heritage's noninterest expense are projected with 40% being realized in 1998 and full realization in 1999. A one-time, pre- tax acquisition charge of approximately $15.5 million will be taken in the quarter the transaction is closed. Commenting on the acquisition, First Midwest Bancorp President and CEO, Robert P. O'Meara, said, "in addition to being the largest, this is clearly the most important acquisition we have made and we couldn't be more excited. This acquisition represents a significant strategic market fill-in that increases our suburban Chicago deposit base by a dramatic 48% while increasing deposits overall by 40%. In Heritage we are talking about southwest Cook County's preeminent bank, a bank that is a historically solid performer and that enjoys longstanding relationships with a variety of commercial and retail customers. With this acquisition we are creating the premier independent suburban Chicago banking franchise." Richard T. Wojcik, Heritage Chairman and CEO, commented, "in First Midwest we found local suburban bankers of a like business philosophy who are both intensely focused on satisfying customers' financial needs and maintaining strong commitments to communities served. We have built a strong franchise and are pleased to be a part of this important new Company." As a result of the combination, First Midwest will enjoy the #1 or #2 deposit market share rank in 3 of the 5 suburban counties contiguous to Cook County, #1 in Will and #2 in each of Lake and McHenry Counties. (Away from suburban Chicago, the Company also holds the #2 deposit share rank in the Illinois-Iowa Quad Cities MSA, the largest banking market in Illinois outside of Chicago.) Heritage's 17 branches will bring First Midwest's suburban Chicago office network to 56 and its total network to 72. This important acquisition magnifies First Midwest's focus on the suburban Chicago market where approximately 85% of the Company's franchise will now be located. With the acquisition, First Midwest's assets increase to approximately $5.0 billion, continuing it as the third largest banking company headquartered in Illinois. It provides commercial banking, trust, investment management, mortgage and related financial services to a variety of consumer, business and governmental customers in 47 communities, primarily in northern Illinois.
