(NASDAQ: FDEF) and ComBanc, Inc. (OTCBB:COBI.OB) today announced the execution of a definitive agreement for First Defiance to acquire ComBanc, Inc. and its wholly owned subsidiary, The Commercial Bank, both headquartered in Delphos, Ohio. With $209 million in assets, The Commercial Bank has four banking offices in Allen County, Ohio: one in Delphos, two in Lima and one in Elida. Combined, the banking offices had $175 million in deposits and $120 million in loans as of June 30, 2004. First Defiance Financial Corp. and ComBanc anticipate that the transaction will be completed early in the first quarter of 2005, pending regulatory approvals, the approval of shareholders of ComBanc and completion of other customary closing conditions. The transaction is valued at $38.0 million, or $17.20 per share, with shareholders of ComBanc having the right to select payment of the purchase price in either cash or shares of First Defiance common stock, subject to an aggregate consideration mix of 50% cash and 50% common stock. . The exchange ratio for the stock portion of the transaction will be based on the market price of First Defiance stock during a pricing period immediately prior to closing, subject to certain adjustments. First Defiance Chairman, CEO and President William J. Small said the acquisition expands First Federal Bank's presence into adjacent markets and supports its growth strategy. "We have a strong presence in northwest Ohio; this acquisition allows us to expand farther south into the west central Ohio market and it adds the type of communities that have been very receptive to our approach to banking," Small said. "The Commercial Bank has a solid base of commercial and retail customers that will be a good complement to our existing franchise. In addition, we believe that First Federal's reputation of customer service combined with a local decision-making strategy will benefit individual and business customers at these new additions to our branch network. We look forward to working with the staff, customers and shareholders of Commercial Bank for a successful transition." "We believe that First Defiance, with its commitment to community banking, is an ideal partner for The Commercial Bank," commented Paul Wreede, Chairman, President and CEO of ComBanc. "We are excited about the opportunities this gives us to expand the product offerings to our existing customers, to attract larger relationships that we couldn't handle with our lower capital base, and to potentially extend our reach to other communities in West Central Ohio. We believe this transaction will produce significant benefits for our shareholders, customers and communities." With the addition of the four ComBanc banking offices, First Defiance will operate 23 First Federal Bank branches and 29 ATM locations in northwest and west central Ohio. "We believe we will be able to quickly integrate these branches into our network based on our success in re-branding three acquired banking offices over one weekend last year," said Mr. Small. "Our strength in community banking is based on the relationships we build in our markets and we have a long-standing tradition of being good corporate citizens," added Mr. Small. "We will be able to provide a true community bank choice for the customers in the Allen County area." First Defiance expects the transaction to be accretive to earnings by $.03 to $.05 per share in 2005 with no repurchase assumptions or revenue synergies assumed. Annual pre-tax expense reductions are estimated to be approximately $1.4 million with approximately 75% to be realized in 2005 and 100% thereafter. Those savings equal approximately 22% of ComBanc, Inc.'s annualized expense base. The companies expect one-time costs, including acquisition-related and restructuring charges, will not exceed $1.75 million on a pre-tax basis over the integration period. Upon completion of the acquisition, on a pro forma basis using June 30, 2004 data, First Defiance Financial Corp. will have $1.278 billion in total assets and $928.5 million in total deposits, with 23 community banking offices in 11 counties.
