("MainSource") jointly announced the signing of a definitive agreement (the "Agreement") pursuant to which the Registrant will be merged with and into MainSource (the "Merger") and the Registrant's savings and loan association subsidiary, Peoples Savings Bank of Troy (the "Bank"), will be merged with and into a new Ohio interim commercial bank subsidiary to be formed by MainSource and named MainSource Bank- Ohio (the "Surviving Bank"). The Agreement provides that upon the effective date of the Merger (the "Effective Time"), pursuant to election procedures described in the Agreement, each share of common stock of the Registrant will be converted into either an amount of cash equal to the Purchase Price (as such number may be adjusted at closing) divided by the number of shares of the Registrant's common stock outstanding at the closing of the Merger (the "Cash Consideration"), or such number of shares of common stock, without par value, of MainSource (the "Exchange Ratio") (as such number may be adjusted at closing) equal to the quotient arrived at by dividing the Cash Consideration by the average of the per share closing prices of a share of MainSource common stock as quoted on the Nasdaq Stock Market during the ten trading days preceding the fifth calendar day preceding the closing of the Merger (the "MainSource Average Stock Price"). If the MainSource Average Stock Price is less than $16.50 per share, the Exchange Ratio will be equal to the Cash Consideration divided by $16.50. However, if the MainSource Average Stock Price is greater than $21.50 per share, the Exchange Ratio will be equal to the Cash Consideration divided by $21.50. Notwithstanding the foregoing, 75% of the total number of outstanding shares of common stock of the Registrant must be converted into MainSource common stock. There may be allocations of cash or stock made to the Registrant's shareholders to ensure that this requirement is satisfied. As of the date hereof, the Purchase Price is $41,057,122, the Cash Consideration is approximately $5.60, and the Exchange Ratio would be 0.3068 shares of MainSource common stock based on MainSource's September 27, 2005 closing. If as of the end of the last business day preceding the closing of the Merger (the "Computation Date"), the Registrant's consolidated shareholders' equity, determined after making adjustments, tax effected (where appropriate), for the items listed below, is less than $23,250,000, the Purchase Price shall be reduced on a dollar-for-dollar basis by an amount equal to the difference between $23,250,000 and the actual consolidated shareholders' equity, as so adjusted, as of the Computation Date. If at the Computation Date such consolidated shareholders' equity is greater than $23,750,000, the Purchase Price shall be increased on a dollar-for-dollar basis by an amount equal to the difference between $23,750,000 and the actual consolidated shareholders' equity, as so adjusted, as of the Computation Date. The adjustments to be made in computing consolidated shareholders' equity are the following: (1) accrual of any dividends scheduled to be declared by the Registrant after the Computation Date; (2) accrued fees payable to the Registrant's investment advisors with respect to the Merger; (3) change-in-control payments payable under employment agreements as a result of the consummation of the Merger; (4) an amount payable by the Registrant as a result of terminating its defined benefit plan; (5) the accrual of all compensable vacation and sick days for employees of the Registrant; (6) the write off of the net book value of POHF's imaging hardware and software; (7) the accrual of an additional $750,000 in loan loss reserves by the Bank above reserves equal to the greater of either $725,090 or 0.42% of total gross loans outstanding on the Computation Date; and -1- (8) any change arising from the purchase or anticipated purchase of the Registrant's common stock from the portion of the Registrant's 401(k) Plan that consists of the assets and liabilities of the Registrant's Employee Stock Ownership Plan will be disregarded or reversed. In connection with the consummation of the Merger, Ronald B. Scott, Richard J. Dutton and John Wannemacher, executive officers of the Registrant and the Bank, will each terminate their existing employment agreements with the Registrant and/or the Bank in exchange for change of control payments under the terms of those agreements. Mr. Scott will enter into a one-year employment agreement with the Surviving Bank at closing. Mr. Scott will serve as its President and Chief Executive Officer, and Mr. Wannemacher will serve as an executive officer of the Surviving Bank. The Merger will be accounted for as a purchase and is expected to close in the first quarter of 2006. The Agreement has been approved by the boards of directors of the Registrant, the Bank and MainSource. However, it is subject to certain other conditions, including the approval of the shareholders of the Registrant and the approval of regulatory authorities.
