Exhibit 99.1 NEWS RELEASE Date: August 23, 2005 4:30 p.m. E.S.T. Contacts: James L. Saner, Sr., President and CEO MainSource Financial Group 812-663-0157 [MainSource logo] Alan L. Grimble, CEO Union Community Bancorp 765-362-2400 MainSource Financial Group and Union Community Bancorp Announce Definitive Agreement MainSource Financial Group, Inc., Greensburg, Indiana (Nasdaq: MSFG) ("MainSource"), and Union Community Bancorp, Crawfordsville, Indiana (Nasdaq: UCBC) ("Union Community"), today jointly announced that they have executed a definitive agreement to merge Union Community into MainSource. Union Community's subsidiary bank, Union Federal Savings and Loan Association ("Union Federal"), will be merged simultaneously into a newly-formed subsidiary of MainSource. The Agreement provides that shareholders of Union Community will have the right to elect to receive cash in the approximate amount of $27.33 per share, or approximately 1.495 shares of MainSource common stock (valued at $27.33, based on MainSource's August 22, 2005 closing price of $18.28 per share) for each share of Union Community common stock owned by them. Based on MainSource's August 22, 2005 closing price and including the anticipated cash out of Union Community stock options, the transaction value is estimated at $56.0 million. The amount of cash or stock payable to Union Community's shareholders may be adjusted at the time of closing based on the amount of Union Community's consolidated shareholders' equity as of the end of the month prior to closing, after certain adjustments prescribed by the agreement have been made, and the closing price of MainSource's common stock prior to closing. However, 55% of the aggregate consideration must be paid in shares of MainSource common stock, and there may be allocations of cash or stock made to shareholders (on the basis of the smallest to the largest shareholders) to ensure that this requirement is satisfied. The transaction, which is expected to close in the first quarter of 2006, is subject to various regulatory approvals and the approval of Union Community's shareholders. The transaction is expected to be accretive to MainSource's earnings per share during the first full year following the transaction. The transaction will allow MainSource to establish a presence in several additional markets and four additional Indiana counties: Crawfordsville, which is in Montgomery County, Covington, which is in Fountain County, Williamsport, which is in Warren County and Lafayette, which is in Tippecanoe County. MainSource currently plans to continue to operate all of Union Community's current offices under the new name "MainSource Bank - Crawfordsville." James L. Saner, Sr., President and Chief Executive Officer of MainSource Financial Group stated, "Union Federal Savings and Loan Association has a long tradition of providing banking services to the people of Montgomery and surrounding counties. We, at MainSource, believe this will be a great partnership because we will be able to offer more products and more services to the residents of these areas. As we transition the bank from a historic savings and loan to a commercial bank a whole array of business products will be added so the bank will be able to meet the needs of not only consumers but also small business, farm, and commercial customers. Alan Grimble and Lee Walden are great additions to our executive team. Alan will become Chairman, President and CEO of the newly formed MainSource Bank in Crawfordsville." He added, "We are committed to local decision-making and we stand firm on our commitment to our community banking philosophy. Our current structure emphasizes regionalized management by local employees, which serves as a cornerstone for MainSource." Under the Agreement, Alan L. Grimble and J. Lee Walden will remain executive officers of the surviving bank, and will maintain Union Federal's current offices in order to continue to serve its customers. Alan Grimble, CEO of Union Community and Union Federal stated, "We are excited to become part of the MainSource family. We believe that the MainSource community banking philosophy will be well received by our Union customers and employees. As part of the MainSource bank network we will eventually be able to offer our customers and local community additional products and services. Given the challenges of being a small public company in today's environment, we believe that this transaction is an excellent opportunity for our shareholders."
