Part I.

ITEM 1.     BUSINESS

(Dollars in thousands except per share data)

GENERAL

MainSource Financial Group, Inc. (“the Company”) is a financial holding company based in Greensburg, Indiana. As of December 31, 2005, the Company owned two banking subsidiaries: MainSource Bank and MainSource Bank of Illinois (together “the Banks”). Through its non-bank affiliates, the Company provides services incidental to the business of banking. Since its formation in 1982, the Company has acquired and established various institutions and financial services companies and may acquire additional financial institutions and financial services companies in the future. For further discussion of the business of the Company see Management’s Discussion and Analysis in Part II, Item 7.

As of December 31, 2005, the Company operated 60 branch banking offices in Indiana and Illinois as well as eight insurance offices in Indiana. As of December 31, 2005, the Company had consolidated assets of $1,645,605, consolidated deposits of $1,352,697 and shareholders’ equity of $161,069.

Through its Banks, the Company offers a broad range of financial services, including: accepting time and transaction deposits; making consumer, commercial, agribusiness and real estate mortgage loans; renting safe deposit facilities; providing general agency personal and business insurance services; providing personal and corporate trust services; and providing other corporate services such as letters of credit and repurchase agreements.

The lending activities of the Banks are separated into primarily the categories of commercial/agricultural, real estate and consumer. Loans are originated by the lending officers of the Banks subject to limitations set forth in lending policies. The Boards of Directors of each Bank reviews loans up to the Bank’s legal lending limits, monitors concentrations of credit, problem and past due loans and charge-offs of uncollectible loans and formulates loan policy. The Banks maintain conservative loan policies and underwriting practices in order to address and manage loan risks. These policies and practices include granting loans on a sound and collectible basis, serving the legitimate needs of the community and the general market area while obtaining a balance between maximum yield and minimum risk, ensuring that primary and secondary sources of repayment are adequate in relation to the amount of the loan, developing and maintaining adequate diversification of the loan portfolio as a whole and of the loans within each category and developing and applying adequate collection policies.

Commercial loans include secured and unsecured loans, including real estate loans, to individuals and companies and to governmental units within the market area of the Banks for a myriad of business purposes.

Agricultural loans are generated in the Banks’ markets. Most of the loans are real estate loans on farm properties. Loans are also made for agricultural production and such loans are generally reviewed annually.

Residential real estate lending has been the largest component of the loan portfolio for many years. All affiliate banks generate residential mortgages for their own portfolios. However, the Company elects to sell the majority of its fixed rate mortgages into the secondary market while maintaining the servicing of such loans.  At December 31, 2005, the Company was servicing a $509 million loan portfolio.  By originating loans for sale in the secondary market, the Company can more fully satisfy customer demand for fixed rate residential mortgages and increase fee income, while reducing the risk of loss caused by rising interest rates.

3

The principal source of revenues for the Company is interest and fees on loans, which accounted for 63.7% of total revenues in 2005, 61.9% in 2004 and 61.8% in 2003.

The Company’s investment securities portfolio is primarily comprised of U. S. Treasuries, federal agencies, state and municipal bonds, mortgage-backed securities and corporate securities. The Company has classified its entire investment portfolio as available for sale, with market value changes reported separately in shareholders’ equity. Funds invested in the investment portfolio generally represent funds not immediately required to meet loan demand. Income related to the Company’s investment portfolio accounted for 18.3% of total revenues in 2005, 16.6% in 2004 and 15.7% in 2003. As of December 31, 2005, the Company had not identified any securities as being “high risk” as defined by the FFIEC Supervisory Policy Statement on Securities Activities.

The primary sources of funds for the Banks are deposits generated in local market areas. To attract and retain stable depositors, the Banks market various programs for demand, savings and time deposit accounts. These programs include interest and non-interest bearing demand and individual retirement accounts.

Currently, national retailing and manufacturing subsidiaries, brokerage and insurance firms and credit unions are fierce competitors within the financial services industry. Mergers between financial institutions within Indiana and neighboring states, which became permissible under the Interstate Banking and Branching Efficiency Act of 1994, have also added competitive pressure.

The Company’s Banks are located in predominantly non-metropolitan areas and their business is centered in loans and deposits generated within markets considered largely rural in nature. In addition to competing vigorously with other banks, thrift institutions, credit unions and finance companies located within their service areas, they also compete, directly and indirectly, with all providers of financial services.

EMPLOYEES

As of December 31, 2005, the Company and its subsidiaries had 617 full-time equivalent employees to whom it provides a variety of benefits and with whom it enjoys excellent relations.

REGULATION AND SUPERVISION OF THE COMPANY

The Company is a financial holding company (“FHC”) within the meaning of the Bank Holding Company Act of 1956, as amended (“Act”). This Act subjects FHC’s to regulations of the Federal Reserve Board (“FRB”) and restricts the business of FHC’s to financial and related activities.

The Gramm-Leach-Bliley Financial Modernization Act of 1999 was enacted on November 12, 1999. The Modernization Act, which amended the Bank Holding Company Act, provides the following:

•it allows bank holding companies that qualify as “financial holding companies” to engage in a broad range of financial and related activities;

•it allows insurers and other financial services companies to acquire banks;

•it removes various restrictions that applied to bank holding company ownership of securities firms and mutual fund advisory companies; and

•it establishes the overall regulatory structure applicable to bank holding companies that also engage in insurance and securities operations.

4

The Company initially qualified as a financial holding company in December, 2004. Thus the Company is authorized to operate as a financial holding company and therefore is eligible to engage in, or acquire companies engaged in, the broader range of activities that are permitted by the Modernization Act. These activities include those that are determined to be “financial in nature,” including insurance underwriting, securities underwriting and dealing, and making merchant banking investments in commercial and financial companies. If any of our banking subsidiaries ceases to be “well capitalized” or “well managed” under applicable regulatory standards, the Federal Reserve Board may, among other things, place limitations on our ability to conduct these broader financial activities or, if the deficiencies persist, require us to divest the banking subsidiary. In addition, if any of our banking subsidiaries receives a rating of less than satisfactory under the Community Reinvestment Act of 1977 (“CRA”), we would be prohibited from engaging in any additional activities other than those permissible for bank holding companies that are not financial holding companies. Our banking subsidiaries currently meet these capital, management and CRA requirements.

Acquisitions by the Company of banks and savings associations are subject to federal and state regulation. Any acquisition by the Company of more than five percent of the voting stock of any bank requires prior approval of the FRB, the FHC and, if applicable, state regulators. Acquisition of savings associations is also subject to the approval of the OTS.

Indiana law permits FHCs to acquire bank holding companies and banks out of state on a reciprocal basis, subject to certain limitations. Under current law, the Company may acquire banks, and may be acquired by bank holding companies, located in any state in the United States that permits reciprocal entry by Indiana FHCs. Under the Act, FHCs may acquire savings associations without geographic restrictions.

A FHC and its subsidiaries are prohibited from engaging in certain tying arrangements in connection with the extension of credit, lease or sale of property, or the provision of any property or service.

The Company is under the jurisdiction of the Securities and Exchange Commission (“SEC”) and state securities commission for matters relating to the offering and sale of its securities. The Company is subject to the SEC’s rules and regulations relating to periodic reporting, reporting to shareholders, proxy solicitation and insider trading.

The Company’s liquidity is principally derived from dividends paid on the common stock of its subsidiaries. The payment of these dividends is subject to certain regulatory restrictions.

Under bank holding company policy, the Company is expected to act as a source of financial strength to, and commit resources to support, its affiliates. As a result of such policy, the Company may be required to commit resources to its affiliate banks in circumstances where it might not otherwise do so.

Certain regulations define relevant capital measures for five capital categories. A “well capitalized” institution is one that has a total risk-based capital ratio of at least 10%, a Tier 1 risk-based capital ratio of at least 8%, a leverage ratio of at least 5% and is not subject to regulatory direction to maintain a specific level for any capital measure. An “adequately capitalized” institution is one that has ratios greater than 8%, 4% and 4%. An institution is “undercapitalized” if its respective ratios are less than 8%, 4% and 4%.  “Significantly undercapitalized” institutions have ratios of less than 6%, 3% and 3%. An institution is deemed to be “critically undercapitalized” if it has a ratio of tangible equity to total assets that is 2% or less. Institutions with capital ratios at levels of “undercapitalized” or lower are subject to various limitations that, in most situations, will reduce the competitiveness of the institution.

5

REGULATION AND SUPERVISION OF THE SUBSIDIARY BANKS

The Company’s affiliate banks are supervised, regulated and examined by their respective state regulatory banking agencies and the Federal Deposit Insurance Corporation (“FDIC”). A cease-and-desist order may be issued against the banks, if the respective agency finds that the activities of the bank represent an unsafe and unsound banking practice or violation of law. The deposits of the two banking subsidiaries are insured to the maximum extent permitted by law by the Bank Insurance Fund (“BIF”) of the FDIC.

Branching by banks in Indiana is subject to the jurisdiction, and requires the prior approval, of the bank’s primary federal regulatory authority and, if the branching bank is a state bank, of the Indiana Department of Financial Institutions (“DFI”). Under Indiana law, banks may branch anywhere in the state.

The Company is a legal entity separate and distinct from its subsidiary Banks.

There are various legal limitations on the extent to which the Banks can supply funds to the Company. The principal source of the Company’s funds consists of dividends from its subsidiary Banks. State and Federal law restricts the amount of dividends that may be paid by banks. In addition, the Banks are subject to certain restrictions on extensions of credit to the Company, on investments in the stock or other securities of the Company and in taking such stock or securities as collateral for loans.

CAPITAL REQUIREMENTS

The Company and its subsidiary Banks must meet certain minimum capital requirements mandated by the FRB, FDIC and DFI. These regulatory agencies require BHCs and banks to maintain certain minimum ratios of primary capital to total assets and total capital to total assets. The FRB requires BHCs to maintain a minimum Tier 1 leverage ratio of 3 percent capital to total assets; however, for all but the most highly rated institutions which do not anticipate significant growth, the minimum Tier 1 leverage ratio is 3 percent plus an additional cushion of 100 to 200 basis points. As of December 31, 2005, the Company’s leverage ratio of capital to total assets was 8.4%. The FRB and FDIC each have approved the imposition of “risk-adjusted” capital ratios on BHCs and financial institutions. The Company’s Tier 1 Capital to Risk-Weighted Assets Ratio was 12.6% and its Total Capital to Risk-Weighted Assets Ratio was 13.5% at December 31, 2005. The Company’s Banks had capital to asset ratios and risk- adjusted capital ratios at December 31, 2005, in excess of the applicable regulatory minimum requirements.

ITEM 1A.               RISK FACTORS

In addition to the other information contained in this report, the following risks may affect us.  If any of these risks  actually occur, our business, financial condition or results of operations may suffer. As a result, the price of our common shares could decline.

Our historical growth and financial performance trends may not continue if our acquisition strategy is not successful.

Growth in asset size and earnings through acquisitions is an important and continuing part of our business strategy.  As consolidation of the banking industry continues, the competition for suitable acquisition candidates may increase.  We compete with other banking companies for acquisition opportunities, and many of these competitors have greater financial resources and acquisition experience than we do and may be able to pay more for an acquisition than we are able or willing to pay.  We also may need additional debt or equity financing in the future to fund acquisitions.  We may not be able to obtain additional financing or, if available, it may not be in amounts and on terms acceptable to us.  We may use our common stock as the consideration for an acquisition or we may issue additional common stock and use the proceeds for the acquisition.  Our issuance of additional securities will dilute your equity interest in us and may have a dilutive effect on our earnings per share.  If we are unable to locate suitable acquisition candidates willing to sell on terms acceptable to us, or we are otherwise unable to obtain additional debt or equity financing necessary for us to continue our acquisition strategy, we would be required to find other methods to grow our business and we may not grow at the same rate we have in the past, or at all.

Acquisitions entail risks which could negatively affect our operations.

Acquisitions involve numerous risks, including:

•      exposure to asset quality problems of the acquired institution;

•      maintaining adequate regulatory capital;

•      diversion of management’s attention from other business concerns;

•      risks and expenses of entering new geographic markets;

•      potential significant loss of depositors or loan customers from the acquired institution; and

•      exposure to undisclosed or unknown liabilities of an acquired institution.

Any of these acquisition risks could result in unexpected losses or expenses and thereby reduce the expected benefits of the acquisition.

Unanticipated costs related to our acquisition strategy could reduce MainSource’s future earnings per share.

MainSource believes it has reasonably estimated the likely costs of integrating the operations of the banks it acquires into MainSource and the incremental costs of operating such banks as a part of the MainSource family.  However, it is possible that unexpected transaction costs such as taxes, fees or professional expenses or unexpected future operating expenses, such as increased personnel costs or increased taxes, as well as other types of unanticipated adverse developments, could have a material adverse effect on the results of operations and financial condition of MainSource.  If unexpected costs are incurred, acquisitions could have a dilutive effect on MainSource’s earnings per share.  In other words, if MainSource incurs such unexpected costs and expenses as a result of its acquisitions, MainSource believes that the earnings per share of MainSource common stock could be less than they would have been if those acquisitions had not been completed.

MainSource may be unable to successfully integrate the operations of the banks it is acquiring and retain employees of such banks.

7

MainSource’s acquisition strategy involves the integration of the banks MainSource is acquiring as MainSource subsidiary banks.  The difficulties of integrating the operations of such banks with MainSource and its other subsidiary banks include:

•     coordinating geographically separated organizations;

•     integrating personnel with diverse business backgrounds;

•     combining different corporate cultures; and

•      retaining key employees.

The process of integrating operations could cause an interruption of, or loss of momentum in, the activities of one or more of MainSource, its subsidiary banks and the banks MainSource is acquiring and the loss of key personnel.  The integration of such banks as MainSource subsidiary banks will require the experience and expertise of certain key employees of such banks who are expected to be retained by MainSource.  We cannot be sure, however, that MainSource will be successful in retaining these employees for the time period necessary to successfully integrate such banks’ operations as subsidiary banks of MainSource.  The diversion of management’s attention and any delays or difficulties encountered in connection with the mergers, along with the integration of the banks as MainSource subsidiary banks, could have an adverse effect on the business and results of operation of MainSource.

Like most banking organizations, our business is highly susceptible to credit risk.

As a lender, we are exposed to the risk that our customers will be unable to repay their loans according to their terms and that the collateral securing the payment of their loans (if any) may not be sufficient to assure repayment. Credit losses could have a material adverse effect on our operating results.

As of December 31, 2005, our total loan portfolio was approximately $958 million or 58% of our total assets. Three major components of the loan portfolio are loans principally secured by real estate, approximately $662 million or 68% of total loans, other commercial loans, approximately $149 million or 16% of total loans, and consumer loans, approximately $123 million or 13% of total loans.  Our credit risk with respect to our consumer installment loan portfolio and commercial loan portfolio relates principally to the general creditworthiness of individuals and businesses within our local market area.  Our credit risk with respect to our residential and commercial real estate mortgage and construction loan portfolio relates principally to the general creditworthiness of individuals and businesses and the value of real estate serving as security for the repayment of the loans.  A related risk in connection with loans secured by commercial real estate is the effect of unknown or unexpected environmental contamination, which could make the real estate effectively unmarketable or otherwise significantly reduce its value as security.

Our allowance for loan losses may not be sufficient to cover actual loan losses, which could adversely affect our earnings.

We maintain an allowance for loan losses in an attempt to cover loan losses inherent in our loan portfolio.  Additional loan losses will likely occur in the future and may occur at a rate greater than we have experienced to date.  In determining the size of the allowance, our management makes various assumptions and judgments about the collectibility of our loan portfolio, including the diversification by industry of our commercial loan portfolio, the effect of changes in the local real estate market on collateral values, the results of recent regulatory examinations, the effects on the loan portfolio of current economic indicators and their probable impact on borrowers, the amount of charge-offs for the period, the amount of nonperforming loans and related collateral security, and the evaluation of our loan portfolio by an external loan review.  If our assumptions and judgments prove to be incorrect, our current allowance may not be sufficient and adjustments may be necessary to allow for different economic conditions or adverse developments in our loan portfolio.  Federal and state regulators also periodically review our allowance for loan losses and may require us to increase our provision for loan losses or recognize further loan charge-offs, based on judgments different than those of our management.  Any increase in our allowance for loan losses or loan charge-offs could have an adverse effect on our operating results and financial condition.

8

We rely heavily on our management and other key personnel, and the loss of any of them may adversely affect our operations.

We are and will continue to be dependent upon the services of our management team, including James L. Saner, Sr., our President and Chief Executive Officer, James M. Anderson, our Senior Vice President and Chief Financial Officer, the presidents of our subsidiary banks and our other senior managers.  The loss of either Mr. Saner or Mr. Anderson, or any of our other senior managers, could have an adverse effect on our growth and performance because of their skills, knowledge of the markets in which we operate and years of industry experience and the difficulty of promptly finding qualified replacement personnel.  The loss of key personnel in a particular market could have an adverse effect on our performance in that market because it may be difficult to find qualified replacement personnel who are already located in or would be willing to relocate to a non-metropolitan market.

Significant interest rate volatility could reduce our profitability.

Our results of operations are affected principally by net interest income, which is the difference between interest earned on loans and investments and interest expense paid on deposits and other borrowings. We cannot predict or control changes in interest rates. National, regional and local economic conditions and the policies of regulatory authorities, including monetary policies of the Board of Governors of the Federal Reserve System, affect market interest rates.  While we have instituted policies and procedures designed to manage the risks from changes in market interest rates, at any given time our assets and liabilities will likely be affected differently by a given change in interest rates, principally because we do not match the maturities of our loans and investments precisely with our deposits and other funding sources.  Changes in interest rates may also affect the level of voluntary prepayments on our loans and the level of financing or refinancing by customers.   As of December 31, 2005, we had a negative interest rate gap of 23% of interest earning assets in the one-year time frame. Although this is within our internal policy limits, our earnings will be adversely affected in periods of rising interest rates because, during such periods, the interest expense paid on deposits and borrowings will generally increase more rapidly than the interest income earned on loans and investments.  If such an interest rate increase occurred gradually, we would use our established procedures to attempt to mitigate the effects over time.  However, if such an interest rate increase occurred rapidly, or interest rates exhibited volatile increases and decreases, we might be unable to mitigate the effects, and our net interest income could suffer significant adverse effects.  While management intends to continue to take measures to mitigate interest rate risk, we cannot assure you that such measures will be entirely effective in minimizing our exposure to the risk of rapid changes in interest rates.

Changes in governmental regulation and legislation could limit our future performance and growth.

We are subject to extensive state and federal regulation, supervision and legislation that govern almost all aspects of our operations, as well as any acquisitions we may propose to make. Any change in applicable federal or state laws or regulations could have a substantial impact on us, our subsidiary banks and our operations. While we cannot predict what effect any presently contemplated or future changes in the laws or regulations or their interpretations would have on us, these changes could reduce the value of your investment.

Our strategy to minimize Indiana state taxes on our investment portfolio may be unsuccessful.

Since 2002, our Indiana state financial institutions taxes have been reduced by our use of subsidiaries we formed in the State of Nevada to hold the investment portfolios of two of our bank subsidiaries.  Nevada has no state or local income tax, and we take the position that none of this income is subject to the Indiana financial institutions tax.  For the year ended December 31, 2005, our net savings in Indiana tax from this arrangement (after federal tax) was approximately $600,000.   Although management believes that this arrangement is permitted under Indiana law, and Indiana tax authorities have not challenged our tax returns in this regard, we understand that Indiana tax authorities have recently challenged a similar arrangement implemented by at least one other Indiana-based bank holding company.   If we were not permitted to realize state tax savings from this arrangement, it would cause our net income after taxes to be lower in the future, and if Indiana tax authorities challenged our arrangement and were successful in assessing additional taxes, interest and penalties for prior years, we might be forced to take a special charge to our earnings in the amount of the assessment.

9

The geographic concentration of our markets makes our business highly susceptible to local economic conditions.

Unlike larger banking organizations that are more geographically diversified, our operations are currently concentrated in 22 counties in Indiana and three counties in Illinois. As a result of this geographic concentration in two fairly contiguous markets, our financial results depend largely upon economic conditions in these market areas. A deterioration in economic conditions in one or both of these markets could result in one or more of the following:

•      an increase in loan delinquencies;

•      an increase in problem assets and foreclosures;

•      a decrease in the demand for our products and services; and

•      a decrease in the value of collateral for loans, especially real estate, in turn reducing customers’ borrowing power, the value of assets associated with problem loans and collateral coverage.

If we do not adjust to rapid changes in the financial services industry, our financial performance may suffer.

We face substantial competition for deposit, credit and trust relationships, as well as other sources of funding in the communities we serve. Competing providers include other banks, thrifts and trust companies, insurance companies, mortgage banking operations, credit unions, finance companies, money market funds and other financial and nonfinancial companies which may offer products functionally equivalent to those offered by our banks. Competing providers may have greater financial resources than we do and offer services within and outside the market areas we serve.  In addition to this challenge of attracting and retaining customers for traditional banking services, our competitors now include securities dealers, brokers, mortgage bankers, investment advisors and finance and insurance companies who seek to offer one-stop financial services to their customers that may include services that banks have not been able or allowed to offer to their customers in the past. The increasingly competitive environment is primarily a result of changes in regulation, changes in technology and product delivery systems and the accelerating pace of consolidation among financial service providers.  If we are unable to adjust both to increased competition for traditional banking services and changing customer needs and preferences, it could adversely affect our financial performance and your investment in our common stock.

ITEM 2.      PROPERTIES

In September 2005, MainSource Financial Group purchased a property in Greensburg, Indiana that will eventually serve as its corporate headquarters.  The Company’s total current investment in this property is $1.2 million and expects to occupy the property by the end of 2006.  As of December 31, 2005, the Company leased space from one of its subsidiaries for use as its corporate headquaters.   The Company's subsidiaries own, or lease, all of the facilities from which they conduct business. All leases are comparable to other leases in the respective market areas and do not contain provisions materially detrimental to the Company or its subsidiaries. As of December 31, 2005 the Company had 60 banking locations of which MainSource Bank had 53 and MainSource Bank of Illinois had 7. In addition, the Company operates eight insurance offices in Indiana. At December 31, 2005, the Company had approximately $28 million invested in premises and equipment.

(Dollar amounts in thousands except per share data)

Forward-Looking Statements

Except for historical information contained herein, the discussion in this Annual Report includes certain forward-looking statements based upon management expectations. Factors which could cause future results to differ from these expectations include the following: general economic conditions; legislative and regulatory initiatives; monetary and fiscal policies of the federal government; deposit flows; the cost of funds; general market rates of interest; interest rates on competing investments; demand for loan products; demand for financial services; changes in accounting policies or guidelines; and changes in the quality or composition of the Company’s loan and investment portfolios.

The forward-looking statements included in the Management’s Discussion and Analysis (“MD&A”) relating to certain matters involve risks and uncertainties, including anticipated financial performance, business prospects, and other similar matters, and reflect management’s best judgment based on factors currently known. Actual results and experience could differ materially from the anticipated results or other expectations expressed in the Company’s forward-looking statements as a result of a number of factors, including but not limited to those discussed in the MD&A.

Overview

MainSource Financial Group, Inc. (“MainSource or Company”) is a financial holding company whose principal activity is the ownership and management of its two wholly owned subsidiary banks (“Banks”): MainSource Bank of Indiana headquartered in Greensburg, Indiana and MainSource Bank of Illinois headquartered in Kankakee, Illinois.  The banks operate under state charters and are subject to regulation by their respective state regulatory agencies and the Federal Deposit Insurance Corporation. MainSource Insurance is a wholly owned subsidiary of the Company operating eight insurance agency offices in Indiana and is subject to regulation by the Indiana Department of Insurance. The Company also has wholly owned subsidiaries to hold investment securities. These investment subsidiaries are incorporated in Nevada. During 2005, the Company also formed MainSource Title, LLC, a title insurance agency, and MainSource Mortgage, LLC, a mortgage origination company.

Business Strategy

The Company operates under the broad tenets of a long-term strategic plan (“Plan”) designed to improve the Company’s financial performance, expand its competitive position and enhance long-term shareholder value. The Plan is premised on the belief of the Company’s board of directors that it can best promote long-term shareholder interests by pursuing strategies which will continue to preserve its community-focused philosophy. The dynamics of the Plan assure continually evolving goals, with the enhancement of shareholder value being the constant, overriding objective. The extent of the Company’s success will depend upon how well it anticipates and responds to competitive changes within its markets, the interest rate environment and other external forces.

The Company continued its history of external growth through acquisitions during 2005. In August 2005, the Company completed its acquisition of The Madison Bank & Trust Company (“Madison) in a cash transaction.  The total consideration paid was $30,267. As of the date of acquisition, Madison had total assets of approximately $200 million.  In addition to the acquisition of Madison, the Company announced three other acquisitions during the second half of 2005.

12

On August 23, 2005, the Company entered into a definitive agreement to acquire Union Community Bancorp (“Union Community”) of Crawfordsville, Indiana. Union Community’s subsidiary financial institution, Union Federal Savings and Loan Association, will be merged into a newly formed subsidiary of the Company.  The agreement provides that shareholders of Union Community will have the right to elect to receive cash, stock, or a combination thereof, in the approximate amount of $27.33 per share for each share of Union Community common stock owned by them. The transaction value is estimated at $56 million. Consideration for 55% of the outstanding Union Community common stock must be paid in shares of MainSource common stock.   MainSource expects to issue approximately 1.6 million shares of its common stock in the transaction.  The transaction is expected to close in the first quarter of 2006 and is subject to various regulatory approvals and the approval of Union Community’s shareholders.

On September 28, 2005, MainSource entered into a definitive agreement to acquire Peoples Ohio Financial Corporation (“Peoples Ohio”) of Troy, Ohio.  Peoples Ohio’s subsidiary bank, Peoples Savings Bank of Troy, will be merged into a newly formed subsidiary of the Company.  The agreement provides that shareholders of Peoples Ohio will have the right to elect to receive cash, stock, or a combination thereof, in the approximate amount of $5.60 per share for each share of Peoples Ohio common stock owned by them.  The transaction value is estimated at $42 million.  Consideration for 75% of the outstanding Peoples Ohio common stock must be paid in shares of MainSource common stock.  MainSource expects to issue approximately 1.7 million shares of its common stock in the transaction.  The transaction, which is expected to close in the second quarter of 2006, is subject to various regulatory approvals and the approval of Peoples Ohio’s shareholders.

On October 26, 2005, MainSource entered into a definitive agreement to acquire HFS Bank, F.S.B. (“HFS”), a federal savings bank located in Hobart, Indiana.  The agreement provides that shareholders of HFS will have the right to elect to receive cash, stock, or a combination thereof, in the approximate amount of $19.35 per share for each share of HFS common stock owned by them. The transaction value is estimated at $36 million.  Consideration for 52% of the outstanding HFS common stock must be paid in shares of MainSource common stock.  MainSource expects to issue approximately 1.0 million shares of its common stock in the transaction.  The transaction, which is expected to close in the second quarter of 2006, is subject to various regulatory approvals and the approval of HFS’ shareholders.

The Company is continuously reviewing other acquisition targets including branches, whole banks, and other financial service related entities focusing on the four-state Midwest region of Indiana, Illinois, Kentucky, and Ohio.

Results of Operations

Net income was $16,192 in 2005, $16,793 in 2004, and $15,305 in 2003.  Earnings per common share on a fully diluted basis were $1.29 in 2005, $1.48 in 2004, and $1.37 in 2003. In the fourth quarter of 2005, the Company elected to restructure a portion of its investment security portfolio.  Approximately $85 million of under-performing securities were sold.  As a result of this action, a pre-tax loss of $2,421 was incurred, which reduced earnings per share for the year by $0.12.  In addition to the aforementioned loss recorded in the fourth quarter, the Company incurred certain costs related to the acquisition of Madison and the consolidation of the Company’s other Indiana banking affiliates. In total, these costs amounted to $700 on a pre-tax basis, or $0.04 per share on an after-tax basis. The Company’s earnings per share for 2005 also include the addition of two million shares of common stock issued in its public offering in June and July of 2005. The offering negatively impacted earnings per share by $0.04 in 2005 as the Company was not able to fully utilize the new capital generated from the offering until the close of its acquisition of Madison, which occurred on August 26, 2005. Therefore, on an operating basis, the Company’s earnings per share would have been $1.49 for the full year 2005 or basically flat when compared to the same period a year ago.

Net Interest Income

Net interest income and net interest margin are influenced by the volume and yield or cost of earning assets and interest-bearing liabilities. Tax equivalent net interest income of $56,205 in 2005 increased from $52,042 in 2004. As rates rose throughout 2005, the Company’s yield on earning assets increased to 5.89% in 2005 from 5.50% in 2004.  Offsetting the decrease in yield, the Company’s deposits and borrowings also repriced throughout the year, although to a lesser extent.  The Company’s total cost of funds was 2.12% in 2005 compared to 1.77% in 2004. The overall effect was an increase in the Company’s net interest margin in 2005 of 12 basis points going from 3.87% in 2004 to 3.99% in 2005.

The following table summarizes net interest income (on a tax-equivalent basis) for each of the past three years.

Non-interest Income

Total non-interest income was $17,332 for 2005 compared to $19,544 for 2004.  Excluding the aforementioned $2,421 loss on the sale of securities incurred in the fourth quarter of 2005, non-interest income would have been $19,753 for 2005 or relatively flat compared to 2004.  Increases in service charges on deposit accounts and other income were offset by decreases in mortgage banking and insurance commissions.  Service charges increased primarily due to the increase in overall account levels from acquisitions.  Other income increased due to death benefits on bank-owned life insurance, the establishment of the title insurance agency, an increase in annuity sales, the acquisition of Madison, and the full-year effect of the Peoples Trust acquisition in June 2004.  Insurance commissions decreased as the Company disposed of the Kentucky division of its insurance subsidiary in the first quarter of 2005.

Non-interest income was relatively flat in 2004 compared to 2003. The acquisition of Peoples Trust and increased service charge income related to the Company’s overdraft program were offset by decreases in mortgage banking activity and lower gains on sales of investment securities. Mortgage banking income was $3,198 in 2004 versus $5,671 in 2003, a decrease of 43.6%. As the level of refinancings declined throughout the year, the Company anticipated this decrease in income.

Non-interest Expense

Total non-interest expense increased 5.9% in 2005 to $48,576 compared to $45,880 in 2004, an increase of $2,696. The largest component of non-interest expense in both years was salaries and employee benefits. These expenses were $27,121 in 2005 compared to $25,411 in 2004. The increase of $1,710 was primarily related to the full-year effect of the acquisition of Peoples Trust, the acquisition of Madison in August 2005, and normal staff salary increases.  Occupancy and intangible amortization expenses increased in 2005 due to the acquisition activity in 2004 and 2005.

15

Total non-interest expense increased 13.4% in 2004 to $45,880 compared to $40,448 in 2003, or an increase of $5,432. The largest component of non-interest expense in both years was salaries and benefits. These expenses were $25,411 in 2004 compared to $22,421 in 2003. The increase of $2,990 was primarily related to the full-year effect of the acquisition of First Community, the acquisition of Peoples Trust in June 2004, and normal staff salary increases. The Company also incurred certain costs in 2004 related to the restructuring of its banking affiliates that were not incurred in 2003.  These costs included system conversion costs, costs associated with the name change of the Company’s Illinois affiliate, and contract termination penalties.  The total restructuring costs incurred in 2004 were $650.

Income Taxes

The effective tax rate was 24.2% in 2005, 27.2% in 2004, and 30.1% in 2003.  The decrease in the Company’s effective tax rate in 2005 was primarily related to an increase in tax-free income from state and municipal securities and an increase in tax-free income related to bank-owned life insurance policies.

Balance Sheet

At December 31, 2005, total assets were $1,645,605 compared to $1,549,379 at December 31, 2004, an increase of $96,226. The increase was primarily attributable to the acquisition of Madison, which accounted for approximately $200 million in assets.  The Company used a portion of the cash received in this acquisition to reduce the overall level of its borrowings.

Loans, Credit Risk and the Allowance and Provision for Loan Losses

Loans remain the Company’s largest concentration of assets and continue to represent the greatest potential risk. The loan underwriting standards observed by the Company’s subsidiaries are viewed by management as a means of controlling problem loans and the resulting charge-offs.

The Company’s conservative loan underwriting standards have historically resulted in higher loan quality and generally lower levels of net charge-offs than peer group averages. The Company also believes credit risks may be elevated if undue concentrations of loans in specific industry segments and to out-of- area borrowers are incurred. Accordingly, the Company’s Board of Directors regularly monitors such concentrations to determine compliance with its loan concentration policy. The Company believes it has no undue concentrations of loans.

Total loans (excluding those held for sale) increased by $28,990 from year-end 2004. The increase was primarily related to the acquisition of Madison, which added $54,835 in net loans. Excluding the acquisition of Madison, the Company’s total loan portfolio decreased by $25,845. This decrease was due primarily to pay offs of approximately $35,000 in the Company’s hotel loan portfolio.  Residential real estate loans continue to represent the largest portion of the total loan portfolio.  Such loans represented 38.5% and 38.1% of total loans at December 31, 2005 and 2004, respectively.

The following table details the Company’s loan portfolio by type of loan.

The Company regards its ability to identify and correct loan quality problems as one of its greatest strengths. Loans are placed on “non-accrual” status when, in management’s judgment, the collateral value and/or the borrower’s financial condition does not justify accruing interest.

16

As a general rule, commercial and real estate loans are reclassified to nonaccrual status at or before becoming 90 days past due. Interest previously recorded is reversed and charged against current income. Subsequent interest payments collected on nonaccrual loans are thereafter applied as a reduction of the loan’s principal balance.

Non-performing loans were $10,217 as of December 31, 2005 compared to $14,042 as of December 31, 2004 and represented 1.07% of total loans at December 31, 2005 versus 1.51% one year ago.

The following table details the Company’s non-performing loans as of December 31 for the years indicated.

The provision for loan losses was $1,040 in 2005, $600 in 2004, and $1,325 in 2003.  The increase in the Company’s provision in 2005 was primarily due to the increase in net charge-offs during 2005. Net charge-offs were $3,299 in 2005 compared to $2,186 in 2004 and $1,411 in 2003. As a percentage of average loans, net charge-offs equaled .35%, .24%, and .18% in 2005, 2004 and 2003, respectively.

Management maintains a list of loans warranting either the assignment of a specific reserve amount or other special administrative attention. This watch list, together with a listing of all classified loans, nonaccrual loans and delinquent loans, is reviewed monthly by the board of directors of each subsidiary. Additionally, the Company evaluates its consumer and residential real estate loan pools for probable losses incurred based on historical trends, adjusted by current delinquency and non-performing loan levels.

The ability to absorb loan losses promptly when problems are identified is invaluable to a banking organization. Most often, losses incurred as a result of prompt, aggressive collection actions are much lower than losses incurred after prolonged legal proceedings. Accordingly, the Company observes the practice of quickly initiating stringent collection efforts in the early stages of loan delinquency.

17

The adequacy of the allowance for loan losses in each subsidiary is reviewed at least quarterly. The determination of the provision amount in any period is based upon management’s continuing review and evaluation of loan loss experience, changes in the composition of the loan portfolio, classified loans including non-accrual and impaired loans, current economic conditions, the amount of loans presently outstanding, and the amount and composition of loan growth. The Company’s allowance for loan losses was $10,441, or 1.09% of total loans, at December 31, 2005 compared to $11,698, or 1.26% of total loans, at the end of 2004. The reduction in non-performing loans supports the decrease in the overall level of the allowance for loan losses.

The acquisition of Madison resulted in an addition to the allowance for loan losses of $1,002.  As of December 31, 2005 management was evaluating the appropriate level of allowance consistent with the probable incurred loss of the portfolio acquired. This acquired allowance is subject to adjustments in the future as part of the finalization of purchase accounting.

Securities

Securities offer flexibility in the Company’s management of interest rate risk, and are the primary means by which the Company provides liquidity and responds to changing maturity characteristics of assets and liabilities. The Company’s investment policy prohibits trading activities and does not allow investment in high-risk derivative products or junk bonds.

As of December 31, 2005, all of the securities are classified as “available for sale” (“AFS”) and are carried at fair value with unrealized gains and losses, net of taxes, excluded from earnings and reported as a separate component of shareholders’ equity. A net unrealized loss of $5,272 was recorded to adjust the AFS portfolio to current market value at December 31, 2005 compared to a net unrealized gain of $175 at December 31, 2004.

Amounts in the table above are based on scheduled maturity dates.  Variable interest rates are subject to change not less than annually based upon certain interest rate indices.  Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

As of December 31, 2005, there were no corporate bonds and other securities which represent more than 10% of shareholders’ equity.

For 2005 the tax equivalent yield of the investment securities portfolio was 4.32%, compared to 3.87% and 3.65% for 2004 and 2003, respectively. The average life of the Company’s investment security portfolio was 5.45 years at December 31, 2005. During 2005 the investment portfolio shifted from a shorter than average duration to a slightly longer than average duration when compared to the Company’s average targeted duration.  This move was in direct response to the aggressive move up in short term interest rates as the Federal Reserve increased rates throughout 2005.  The duration extension allowed the portfolio to improve its yield performance throughout the year.  At the end of 2005 management determined that a selective divestiture of underperforming securities would better position the portfolio for the future.  The transaction resulted in a one time pre-tax loss on sale of $2,421 that is expected to be recovered in the next 18 months.  Entering 2006 the portfolio is now positioned to provide consistent yield performance and stable cash flows for reinvestment.  Management anticipates that the portfolio will likely maintain its current duration and expects limited changes to its overall yield performance.

Sources of Funds

The Company relies primarily on customer deposits and securities sold under agreement to repurchase (“repurchase agreements”), along with shareholders’ equity to fund earning assets. Federal Home Loan Bank (“FHLB”) advances are used to provide additional funding. The Company also attempts to obtain deposits through branch acquisitions.

Deposits generated within local markets provide the major source of funding for earning assets. Average total deposits were 88.5% and 89.6% of total average earning assets in 2005 and 2004, respectively. Total interest-bearing deposits averaged 88.4% and 89.1% of average total deposits during 2005 and 2004. Management is continuing efforts to increase the percentage of transaction-related deposits to total deposits due to the positive effect on earnings.

Repurchase agreements are high denomination investments utilized by public entities and commercial customers as an element of their cash management responsibilities. During 2005, repurchase agreements averaged $21,661.

Another source of funding is the Federal Home Loan Bank (FHLB). The Company had FHLB advances of $41,547 outstanding at December 31, 2005. These advances have interest rates ranging from 2.4% to 6.3% (see note 10 to the consolidated financial statements for the maturity schedule of these advances). The Company averaged $89,674 in FHLB advances during 2005 compared to $69,861 during 2004.

Capital Resources

The Federal Reserve Board and other regulatory agencies have adopted risk-based capital guidelines that assign risk weightings to assets and off-balance sheet items. The Company’s core capital (“Tier 1”) consists of common shareholders’ equity adjusted for unrealized gains or losses on available for sale (AFS) securities plus limited amounts of Trust Preferred Securities less goodwill and intangible assets. Total capital consists of core capital, certain debt instruments and a portion of the allowance for loan losses. At December 31, 2005, Tier 1 capital to average assets was 8.4%. Total capital to risk-weighted assets was 13.5%. Both ratios exceed all required ratios established for bank holding companies. Risk-adjusted capital levels of each of the Company’s subsidiary banks exceed regulatory definitions of well-capitalized institutions.

19

The Trust Preferred Securities (which are classified as subordinated debentures) qualify as Tier 1 capital or core capital with respect to the Company under the risk-based capital guidelines established by the Federal Reserve. Under such guidelines, capital received from the proceeds of the sale of these securities cannot constitute more than 25% of the total Tier 1 capital of the Company. Consequently, the amount of Trust Preferred Securities in excess of the 25% limitation constitutes Tier 2 capital, or supplementary capital, of the Company.  As of December 31, 2005, all of the Company’s Trust Preferred Securities qualify as Tier 1 capital.

Common shareholders’ equity is impacted by the Company’s decision to categorize its securities portfolio as available for sale (AFS). Securities in this category are carried at fair value, and common shareholders’ equity is adjusted to reflect unrealized gains and losses, net of taxes.

The Company declared and paid common dividends of $.520 per share in 2005 compared to $.476 and $.435 in 2004 and 2003 respectively. Book value per common share increased to $11.96 at December 31, 2005 compared to $10.68 at the end of 2004. The net adjustment for AFS securities decreased book value per share by $.23 at December 31, 2005 and increased book value per share by $.01 at December 31, 2004. Depending on market conditions, the adjustment for AFS securities can cause significant fluctuations in equity.

Liquidity

Liquidity management involves maintaining sufficient cash levels to fund operations and to meet the requirements of borrowers, depositors and creditors. Higher levels of liquidity bear higher corresponding costs, measured in terms of lower yields on short-term, more liquid earning assets and higher interest expense involved in extending liability maturities. Liquid assets include cash and cash equivalents, loans and securities maturing within one year and money market instruments. In addition, the Company holds approximately $425 million of AFS securities maturing after one year, which can be sold to meet liquidity needs.

Maintaining a relatively stable funding base, which is achieved by diversifying funding sources, supports liquidity, extends the contractual maturity of liabilities, and limits reliance on volatile short-term purchased funds. Short-term funding needs may arise from declines in deposits or other funding sources, funding of loan commitments and requests for new loans. The Company’s strategy is to fund assets to the maximum extent possible with core deposits, which provide a sizable source of relatively stable low-cost funds. The Company defines core deposits as all deposits except certificates of deposits greater than $100. Average core deposits funded approximately 78.8% of total earning assets during 2005 and approximately 79.3% in 2004.

Management believes the Company has sufficient liquidity to meet all reasonable borrower, depositor and creditor needs in the present economic environment. The Company has not received any directives from regulatory authorities that would materially affect liquidity, capital resources or operations.

Interest Rate Sensitivity

At year-end 2005, the Company held approximately $666 million in assets comprised of securities, loans, short-term investments, and federal funds sold, which were interest rate sensitive in one year or less time horizons. The Company’s interest rate sensitivity analysis for the year ended December 31, 2005 appears in the table below. A significant assumption that creates the large negative gap in the 0 to 3 month category is that all interest-bearing demand and savings accounts are subject to immediate repricing. While it is true that, contractually, those accounts are subject to immediate repricing, the rates paid on those accounts are generally not tied to specific indices and are influenced by market conditions and other factors. Accordingly, a general movement in interest rates, either up or down, may not have any immediate effect on the rates paid on these deposit accounts. The following table illustrates only one source of information about sensitivity to interest rate movements. Our asset and liability management process also uses simulations that take into account the time that various assets and liabilities may reprice and the degree to which various categories of such assets and liabilities will respond to general interest rate movements. Interest rate risk can only be represented by a measurement of the effects of changing interest rates given the capacity for and magnitude of change on specific assets and liabilities.

Management believes that the Company has taken steps to position itself to react to changes in the current interest rate environment.  Short term interest rates rose significantly in 2005 as the Federal Reserve increased rates in response to a maturing economic expansion.  The Company was able to increase its margin in this environment but increased deposit pricing competition will likely pressure this trend in 2006.  The Company continues to monitor the repricing characteristics of its balance sheet so as to maintain an acceptable net interest margin during interest rate fluctuations. Assuming a stable to moderately higher interest rate environment, the Company does not foresee its earnings materially impacted for 2006.

Asset/liability management strategies are developed by the Company to manage market risk. Market risk is the risk of loss in financial instruments including investments, loans, deposits and borrowings arising from adverse changes in prices/rates. Interest rate risk is the Company’s primary market risk exposure and represents the sensitivity of earnings to changes in market interest rates.

The following table provides information about the Company’s significant financial instruments at December 31, 2005 that are sensitive to changes in interest rates. The table presents principal cash flows and related weighted average interest rates by maturity dates. The table presents only a static measurement of asset and liability volumes based on maturity, cash flow estimates and interest rates. It does not reflect the differences in the timing and degree of repricing of assets and liabilities due to interest rate changes.

In analyzing interest rate sensitivity, management considers these differences and incorporates other assumptions and factors, such as balance sheet growth and prepayments, to better measure interest rate risk. The Company cannot make any assurances as to the outcome of these assumptions, nor can it assess the impact of customer product preference changes and competitive factors as well as other internal and external variables. In addition, this analysis cannot reflect actions taken by the asset/liability management committees; therefore, this analysis should not be relied upon as indicative of expected operating results.

Effects of Changing Prices

The Company’s asset and liability structure is substantially different from that of an industrial company in that most of its assets and liabilities are monetary in nature. Management believes the impact of inflation on financial results depends upon the Company’s ability to react to changes in interest rates and, by such reaction, reduce the inflationary impact on performance. Interest rates do not necessarily move in the same direction at the same time, or at the same magnitude, as the prices of other goods and services. As discussed previously, management relies on its ability to manage the relationship between interest-sensitive assets and liabilities to protect against wide interest rate fluctuations, including those resulting from inflation.

22

Critical Accounting Policies

The accounting and reporting policies of the Company comply with accounting principles generally accepted in the United States and conform to general practices within the banking industry. These policies require estimates and assumptions. Changes in underlying factors, assumptions, or estimates in any of these areas could have a material impact on the Company’s future financial condition and results of operations. In management’s opinion, some of these areas have a more significant impact than others on the Company’s financial reporting. These areas currently include accounting for the allowance for loan losses and goodwill.

Allowance for Loan Losses — The level of the allowance for loan losses is based upon management’s evaluation of the loan and lease portfolios, past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay (including the timing of future payments), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, and other pertinent factors. This evaluation is inherently subjective as it requires material estimates including the amounts and timing of future cash flows expected to be received on impaired loans that may be susceptible to significant change. The level of allowance maintained is believed by management to be adequate to cover losses inherent in the portfolio. The allowance is increased by provisions charged to expense and decreased by charge-offs, net of recoveries of amounts previously charged-off.

Goodwill — Statement of Financial Accounting Standards No. 141 “Business Combinations” and No. 142 “Goodwill and Other Intangible Assets” were issued in June of 2001 and were effective for fiscal years beginning after December 15, 2001. Under these rules, goodwill and intangible assets deemed to have indefinite lives, if any, will no longer be amortized, but will be subject to annual impairment tests in accordance with the Statements. The Company has selected June 30 as its date for annual impairment testing.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(Dollar amounts in thousands except per share data)

NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations and Principles of Consolidation:  The consolidated financial statements include MainSource Financial Group, Inc. and its wholly owned subsidiaries, together referred to as “the Company”.  Intercompany transactions and balances are eliminated in consolidation.

The Company’s wholly owned subsidiaries include MainSource Bank, MainSource Bank of Illinois (formerly known as Capstone Bank), MainSource Insurance, LLC, MainSource Title, LLC, MainSource Mortgage, LLC, and IUB Reinsurance Company, Ltd.  In February 2005, the Company disposed of the Kentucky division of its insurance subsidiary.  The disposition did not result in a significant gain or loss to the Company as it was sold at its approximate book value.  In February 2005, the Company merged its wholly-owned subsidiary of Regional Bank into MainSource Bank and in October 2005, the Company merged its wholly-owned subsidiary of Peoples Trust Company into MainSource Bank.

The Company provides financial services through its offices in Indiana and Illinois.  Its primary deposit products are checking, savings, and term certificate accounts, and its primary lending products are residential mortgage, commercial, and installment loans.  Substantially all loans are secured by specific items of collateral including business assets, consumer assets and real estate.  Commercial loans are expected to be repaid from cash flow from operations of businesses.  Real estate loans are secured by both residential and commercial real estate.  Other financial instruments which potentially represent concentrations of credit risk include deposit accounts in other financial institutions and federal funds sold.

Use of Estimates:  To prepare financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions based on available information.  These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided and actual results could differ.  The allowance for loan losses, loan servicing rights, and fair values of financial instruments are particularly subject to change.

Cash Flows:  Cash and cash equivalents include cash and due from banks, interest bearing deposits with other financial institutions with maturities under 90 days, money market funds and federal funds sold.  Net cash flows are reported for loan and deposit transactions, federal funds purchased and repurchase agreements.

Securities:  Securities are classified as held to maturity and carried at amortized cost when management has the positive intent and ability to hold them to maturity.  Securities are classified as available for sale when they might be sold before maturity.  Securities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income.

Interest income includes amortization of purchase premium or discount.  Premiums and discounts on securities are amortized on the level-yield method, which considers prepayments on mortgage-backed securities.  Gains and losses on sales are based on the amortized cost of the security sold.  Declines in the fair value of securities below their cost that are other than temporary are reflected as realized losses.  In estimating other-than-temporary losses, management considers (1) the length of time and extent that fair value has been less than cost, (2) the financial condition and near term prospects of the issuer, and (3) the Company’s ability and intent to hold the security for a period sufficient to allow for any anticipated recovery in fair value.

Loans Held for Sale:  Loans originated and intended for sale in the secondary market are carried at the lower of cost or market in the aggregate.  Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings.

Mortgage loans held for sale are generally sold with servicing rights retained.  The carrying value of mortgage loans sold is reduced by the cost allocated to the servicing right.  Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.

30

Loans:  Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of unearned interest, deferred loan fees and costs, and an allowance for loan losses.  Interest income is accrued on the unpaid principal balance.  Loan originations fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments.

Interest income is not reported when full loan repayment is in doubt, typically when the loan is impaired or payments are past due over 90 days.  Loans are placed on non-accrual or charged-off at an earlier date if collection of principal or interest is considered doubtful.

All interest accrued but not received for loans placed on nonaccrual is reversed against interest income.  Payments received on such loans subsequent to being placed on non-accrual are applied to the principal balance of the loans.  Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Allowance for Loan Losses:  The allowance for loan losses is a valuation allowance for probable incurred credit losses.  Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed.  Subsequent recoveries, if any, are credited to the allowance.  Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors.  Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off.

The allowance consists of specific and general components.  The specific component relates to loans that are individually classified as impaired or loans otherwise classified as substandard or doubtful.  The general component covers pools of other loans and is based on historical loss experience adjusted for current factors.

A loan is impaired when full payment under the loan terms is not expected.  Impairment is evaluated in total for smaller-balance loans of similar nature such as residential real estate and consumer loans, and is not separately identified for impairment disclosure.  Other loans are evaluated individually for impairment.  If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral.

Federal Home Loan Bank (FHLB) Stock:  The Bank is a member of the FHLB system.  Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts.  FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment.  Because this stock is viewed as long term investment, impairment is based on ultimate recovery of par value.  Both cash and stock dividends are reported as income.

Foreclosed Assets:  Assets acquired through or instead of loan foreclosure are initially recorded at fair value when acquired net of estimated selling costs, establishing a new cost basis.  If fair value declines after acquisition, a valuation allowance is recorded through expense.  Costs after acquisition are expensed.

Premises and Equipment:  Land is carried at cost.  Premises and equipment are stated at cost less accumulated depreciation.  Buildings and related components are depreciated using the straight-line method with useful lives ranging from 30 to 39 years for buildings and 5 to 15 years for components.  Furniture, fixtures and equipment are depreciated using the straight-line method with useful lives ranging from 3 to 10 years.

31

Company Owned Life Insurance:  The Company has purchased life insurance policies on certain employees.  Company owned life insurance is recorded at its cash surrender value, or the amount that can be realized.

Servicing Assets:  Servicing assets represent the allocated value of retained servicing rights on loans sold.  Servicing assets are expensed in proportion to, and over the period of, estimated net servicing revenues.  Impairment is evaluated based on the fair value of the assets, using groupings of the underlying loans as to product type and interest rates.  Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market-based assumptions.  Any impairment of a grouping is reported as a valuation allowance, to the extent that fair value is less than the capitalized amount for a grouping.

Transfers of Financial Assets:  Transfers of financial assets are accounted for as sales when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement or option to repurchase them before their maturity.

Goodwill and Other Intangible Assets:  Goodwill results from business acquisitions and represents the excess of the purchase price over the fair value of acquired tangible assets and liabilities and identifiable intangible assets. Goodwill is assessed at least annually for impairment and any such impairment will be recognized in the period identified.

Other intangible assets consist of core deposit intangibles arising from whole bank and branch acquisitions.  They are initially measured at fair value and then are amortized on an accelerated method over their estimated useful lives, generally ten years.

Long-term Assets:Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows.  If impaired, the assets are recorded at fair value.

Repurchase Agreements:  Substantially all repurchase agreement liabilities represent amounts advanced by various customers.  Securities are pledged to cover these liabilities, which are not covered by federal deposit insurance.  Repurchase agreements are included in short-term borrowings on the consolidated balance sheets.

Income Taxes:  Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities.  Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates.  A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized.

Loan Commitments and Related Financial Instruments:  Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs.  The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay.  Such financial instruments are recorded when they are funded.

Derivatives:  All derivative instruments are recorded at their fair values.  If derivative instruments are designated as hedges of fair values, both the change in the fair value of the hedge and the hedged item are included in current earnings.  Fair value adjustments related to cash flow hedges are recorded in other comprehensive income and reclassified to earnings when the hedged transaction is reflected in earnings.  Ineffective portions of hedges are reflected in earnings as they occur.

32

Mortgage Banking Income:  Mortgage banking income consists of gains on loan sales, mortgage servicing rights, and loan servicing fee income, net of amortization of mortgage servicing rights.

Stock Compensation:  Compensation expense for stock options is reported using the intrinsic value method.  No stock-based compensation cost is reflected in net income, as all options granted had an exercise price equal to or greater than the market price of the underlying common stock at date of grant.  The following table illustrates the effect on net income and earnings per share if expense was measured using the fair value recognition provisions of FASB Statement No. 123, “Accounting for Stock-Based Compensation”.  During 2005, the Company accelerated vesting on selected pools of stock options granted in order to reduce expense that would have been recognized upon adoption of FAS 123R.

	2005		2004		2003
Net income as reported	$	16,192	$	16,793	$	15,305
Deduct: Stock-based compensation expense, net, determined under fair value based method	517		92		29
Pro forma net income	$	15,675	$	16,701	$	15,276
Basic earnings per share as reported	$	1.29	$	1.48	$	1.37
Pro forma basic earnings per share	$	1.25	$	1.47	$	1.37
Diluted earnings per share as reported	$	1.29	$	1.48	$	1.37
Pro forma diluted earnings per share	$	1.25	$	1.47	$	1.37

The pro forma effects are computed using option pricing models, with the following weighted-average assumptions for 2005 as of grant date: risk-free interest rate 4.08%, expected option life 6.83 years, expected stock price volatility 21.64% and dividend yield 2.50%.  For 2004, the following weighted-average assumptions were used as of the grant date: risk-free interest rate 3.48%, expected option life 6.69 years, expected stock price volatility 20.34% and dividend yield 2.75%.  For 2003, the following weighted-average assumptions were used as of the grant date: risk-free interest rate 2.80%, expected option life 6.54 years, expected stock price volatility 18.60% and dividend yield 2.90%.

Earnings Per Common Share:  Basic earnings per common share is net income divided by the weighted average number of common shares outstanding during the period.  Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options.  Earnings and dividends per share are restated for all stock splits and dividends through the date of issue of the financial statements.

Comprehensive Income:  Comprehensive income consists of net income and other comprehensive income.  Other comprehensive income includes unrealized gains and losses on securities available for sale and unrealized gains and losses on cash flow hedges, which are also recognized as a separate component of equity. 

Loss Contingencies:  Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated.  Management does not believe there are now any such matters that will have a material effect on the financial statements.

Dividend Restriction:  Banking regulations require maintaining certain capital levels and may limit the dividends paid by the banks to the holding company or by the holding company to shareholders.  These

33

restrictions pose no practical limit on the ability of the banks or holding company to pay dividends at historical levels.

Fair Value of Financial Instruments:  Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note.  Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items.  Changes in assumptions or in market conditions could significantly affect the estimates.

Operating Segments:  While the Company’s chief decision-makers monitor the revenue streams of the various Company products and services, the identifiable segments are not material and operations are managed and financial performance is evaluated on a Company-wide basis.  Accordingly, all of the Company’s financial service operations are considered by management to be aggregated in one reportable operating segment.

Reclassifications:  Some items in the prior year financial statements were reclassified to conform to the current presentation.

Recently Issued Accounting Standards: During 2005, the Company adopted the following accounting standards and guidance: SOP 03-3 and FASB Staff Position 115-1.  Additionally, the Company will adopt FAS 123R on January 1, 2006.  The impact of these issues is discussed below.

SOP 03-3 requires that acquired loans to be recorded at the amount of the purchaser’s initial investment and prohibits carrying over valuation allowances from the seller for those individually evaluated loans that have evidence of deterioration in credit quality since origination, and it is probable all contractual cash flows on the loan will be unable to be collected.  SOP 03-3 also requires the excess of all undiscounted cash flows expected to be collected at acquisition over the purchaser’s initial investment to be recognized as interest income on a level-yield basis over the life of the loan.  Subsequent increases in cash flows expected to be collected are recognized prospectively through an adjustment of the loan’s yield over its remaining life, while subsequent decreases are recognized as impairment.  Management adopted the provision of SOP 03-03 effective January 1, 2005.  The adoption of this standard did not have a material impact on financial condition, results of operation, or liquidity as no material amount of loans acquired in the current year fell within the scope of this standard.

In November 2005, the Financial Accounting Standards Board (FASB) issued FASB Staff Position 115-1, “The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments.”  This FSP provides additional guidance on when an investment in a debt or equity security should be considered impaired and when that impairment should be considered other-than-temporary and recognized as a loss in earnings.  Specifically, the guidance clarifies that an investor should recognize an impairment loss no later than when the impairment is deemed other-than-temporary, even if a decision to sell has not been made.  The FSP also requires certain disclosures about unrealized losses that have not been recognized as other-than-temporary impairments.  Management applied this guidance in this FSP in 2005.

FAS 123, Revised, requires all public companies to record compensation cost for stock options provided to employees in return for employee service.  The cost is measured at the fair value of the options when granted, and this cost is expensed over the employee service period, which is normally the vesting period of the options.  This will apply to awards granted or modified in fiscal years beginning in 2006.  Compensation cost will also be recorded for prior option grants that vest after the date of adoption.  The effect on results of operations will depend on the level of future option grants and the calculation of the fair value of the options granted at such future date, as well as the vesting periods provided, and so cannot currently be predicted.  Existing options that will vest after adoption date are expected to result in additional compensation expense of approximately $28 during 2006, $13 in 2007, $3 in 2008, and $2 in 2009.

NOTE 2 – BUSINESS COMBINATIONS

In August 2005, the Company acquired 100% of the outstanding shares of The Madison Bank & Trust Company.  Operating results of this acquisition are included in the consolidated financial statements since the date of the acquisition.  As a result of this acquisition, the Company expects to further solidify its market share in the southern Indiana market, expand its customer base to enhance deposit fee income, provide an opportunity to market additional products and services to new customers, and reduce operating costs through economies of scale.

The aggregate purchase price was $30.3 million in cash.  The purchase price resulted in approximately $12.0 million in goodwill, and $4.2 million in core deposit intangible.  The core deposit intangible asset is being amortized over 10 years, using an accelerated method.  Goodwill will not be amortized but will instead be evaluated periodically for impairment.  Goodwill and intangible assets will be deducted for tax purposes over 15 years using a straight line method.  As of the date of this report, the Company was in the process of obtaining third party valuations and completing fair value estimates for certain assets acquired and liabilities assumed, and the allocation of the purchase price is subject to refinement.

The following table summarizes the estimated fair value of assets acquired and liabilities assumed at the date of acquisition.

Cash	$	142,046
Loans, net	54,835
Goodwill	11,990
Core deposit intangible	4,151
Other assets	2,372
Total assets acquired	215,394
Deposits	(184,704		)
Other liabilities	(423		)
Total liabilities assumed	(185,127		)
Net assets acquired	$	30,267

Pending Acquisitions:

In August 2005, the Company executed a definitive agreement to acquire Union Community Bancorp (“Union”).  Union, which has approximately $255 million in assets, operates a total of six offices in Montgomery, Fountain, Warren, and Tippecanoe Counties in Indiana through its wholly-owned subsidiary, Union Federal Bank and Trust Association.  The transaction is expected to close in the first quarter of 2006.

In September 2005, the Company executed a definitive agreement to acquire Peoples Ohio Financial Corporation (“Peoples”).  Peoples, which has approximately $201 million in assets, operates a total of six offices in Montgomery and Miami Counties in Ohio through its wholly-owned subsidiary, Peoples Savings Bank of Troy.  The transaction is expected to close in the second quarter of 2006.

In October 2005, the Company executed a definitive agreement to acquire HFS Bank, F.S.B. (“HFS”).  HFS, which has approximately $236 million in assets, operates a total of six offices in Hobart, Portage, Griffith and Crown Point, Indiana.  The transaction is expected to close in the second quarter of 2006.

Unrealized losses on state and municipal securities have not been recognized into income because  management has the intent and ability to hold for a period of time sufficient to allow for any anticipated recovery in fair value.   The fair value of debt securities is expected to recover as the securities approach their maturity date.

Unrealized losses on mortgage-backed securities and agencies have not been recognized into income as the decline in fair value  is largely due to increases in market interest rates.  The fair value is expected to recover as the bonds approach their maturity date  and/or market rates decline.

Total short-term borrowings	$	26,516	$	57,175

Securities sold under repurchase agreements (“agreements”) consist of obligations secured by Federal agency securities, and a safekeeping agent holds such collateral.  The maximum amount of outstanding repurchase agreements at any month-end during 2005, 2004, and 2003 totaled $28,581, $28,782, and $20,048.  The daily average of such agreements during 2005, 2004, and 2003 totaled $21,661, $22,166, and $16,680.   The weighted average rate was 2.36%, 1.34%, and 0.71% at December 31, 2005, 2004, and 2003 while the weighted  average rate during 2005, 2004, and 2003 was approximately 1.98%, 0.96%, and 0.88% respectively.  The majority  of the agreements at December 31, 2005 mature within 30 days.

The Company has a revolving credit facility for $30,000 as a standby for funding needs which matures July 1, 2007.   The interest rate is 120 basis points above the 3-month LIBOR rate which resulted in a rate of 5.72% at year-end 2005.   There was no outstanding balance as of December 31, 2005.  The line is secured by the stock of MainSource Bank.

NOTE 12 – SUBORDINATED DEBENTURES

The Company formed three separate trusts in 2002 and 2003 that issued floating rate trust preferred securities as part of pooled offerings.  The Company issued subordinated debentures to the trusts in exchange for the proceeds of the offerings, which debentures represent the sole asset of the trusts.  Under FAS Interpretation No. 46, the trusts are no longer consolidated with the Company.  Other than the items detailed below, the terms of the subordinated debentures are generally the same.  Interest payments are payable quarterly in arrears and the Company has the option to defer interest payments from time to time for a period not to exceed 20 consecutive quarters.  The subordinated debentures mature in 30 years from issuance and can be called anytime after five years at par.   The following table summarizes the other terms of each issuance.

	Issuance	Amount		Variable Rate		Rate as of 12/31/05		Maturity
Trust 1	2002	$	8,248	LIBOR +3.25	%	7.77	%	2032

During 2003, the Company entered into an interest rate swap and cap to mitigate overall risk to changes in interest rates.  Both the interest rate swap and the cap have a 60 month term and a notional principal amount of $14,000.  The notional amount of the interest rate swaps do not represent amounts exchanged by the parties.  The amount exchanged is determined by reference to the notional amounts and other terms of the contract.  The interest rate swap and cap were designated as cash flow hedges against a portion of the subordinated debentures.  As such, the aggregate fair value of the swaps are recorded as other assets or other liabilities with changes in the fair value recorded in other comprehensive income and no amount of ineffectiveness was included in net income.  Under the interest rate swap agreement, the Company made fixed rate payments at 6.65%, and received variable payments based on LIBOR.  Net settlement expense or benefit is included in interest expense.  A payment of $23 was due to the Company at December 31, 2005.  The interest rate cap requires the counter-party to pay the Company the excess of 3 month LIBOR over 12%.  The fair value for the interest rate swap and cap was $426 at December 31, 2005 and was included in other assets.  The fair value was $52 at December 31, 2004 and was included in other assets.  Both the interest rate swap and cap expire in April 2008.

NOTE 13 - - LOAN SERVICING

Loans serviced for others are not included in the accompanying consolidated balance sheets. The unpaid principal balances of loans serviced for others totaled $509,211 and $500,797 at December 31, 2005 and 2004. Mortgage servicing rights are included in other assets on the consolidated balance sheets.  The fair value of capitalized mortgage servicing assets is based on comparable market values and expected cash flows, with impairment assessed based on portfolio characteristics including product type and interest rates.  No valuation allowance was necessary during 2005 or 2004. The fair market value of capitalized mortgage servicing rights was $4,861 and $4,789 at year end 2005 and 2004.

The Company has a state operating loss carryforward of $5,200, which begins to expire in 2019.

Retained earnings of MainSource Bank include approximately $2,162 for which no deferred income tax liability has been recognized.  This amount represents an allocation of income to bad debt deductions as of  December 31, 1987 for tax purposes only.  Reduction of amounts so allocated for purposes other than tax bad debt losses including redemption of MainSource Bank stock or excess dividends, or loss of “bank” status for MainSource Bank would create income for tax purposes only, which  would be subject to the then-current corporate income tax rate.  The unrecorded deferred income tax liability on the above amount for MainSource at December 31, 2005 was approximately $757.

NOTE 16 - COMMITMENTS

Some financial instruments, such as loan commitments, credit lines, letters of credit,  and overdraft protection, are issued to meet customer financing needs.  These are  agreements to provide credit or to support the credit of others, as long as conditions  established in the contract are met, and usually have expiration dates.  Commitments  may expire without being used.  Off-balance-sheet risk to credit loss exists up to the  face amount of these instruments, although material losses are not anticipated.  The  same credit policies are used to make such commitments as are used for loans,  including obtaining collateral at exercise of the commitment.

Financial instruments whose contract amount represents credit risk as of December 31 were as follows:

	2005		2004
Commitments to extend credit	$	222,373	$	155,280
Commercial letters of credit	14,404		17,925

Commitments are predominantly short-term or variable in rate.

On November 29, 2004, the Company announced a 5% stock dividend to be paid on January 15, 2005 to shareholders of record as of December 31, 2004.  The stock dividend was recorded in 2004, and all share and per share amounts have been retroactively adjusted for all prior years to reflect this stock dividend.

On March 16, 2004, the Company announced a 3-for-2 stock split to be distributed on April 16, 2004 to shareholders of record as of March 31, 2004.  The stock split was recorded in 2004, and all share and per share amounts have been retroactively adjusted for all prior years to reflect this stock split.

On November 26, 2003, the Company announced a 5% stock dividend to be paid on January 9, 2004 to shareholders of record as of December 22, 2003.  The stock dividend was recorded in 2003, and all share and per share amounts have been retroactively adjusted for all prior years to reflect this stock dividend.

51

NOTE 18 - DIVIDENDS

Without prior approval, the Banks are restricted by state and federal regulations as to the maximum amount of dividends they can pay to the holding company in any calendar year.  The Banks may dividend their retained net profits (as defined) for that year and the two preceding years.  From time to time, the holding company may seek the approval of the appropriate regulatory authorities to allow the banks to pay additional dividends to the holding company in excess of the aforementioned amount.  At December 31, 2005, total shareholders’ equity of the Banks was $171,516 of which $170,238 was restricted or limited from dividend distribution to the holding company.

NOTE 19 – DIVIDEND REINVESTMENT PLAN

The Company maintains an Automatic Dividend Reinvestment Plan.  The plan enables shareholders to elect to have their cash dividends on all or a portion of shares held automatically reinvested in additional shares of the Company’s common stock. The stock is purchased by the Company’s transfer agent on the open market and credited to participant accounts at fair market value.  Dividends are reinvested on a quarterly basis.

52

NOTE 20 - REGULATORY CAPITAL

Banks and bank holding companies are subject to various regulatory capital requirements administered by the federal banking agencies and are assigned to a capital category. The assigned capital category is largely determined by three ratios that are calculated according to the regulations. The ratios are intended to measure capital relative to assets and credit risk associated with those assets and off-balance sheet exposures. The capital category assigned to an entity can also be affected by qualitative judgments made by regulatory agencies about the risk inherent in the entity’s activities that are not part of the calculated ratios.

There are five capital categories defined in the regulations, ranging from well capitalized to critically undercapitalized. Classification in any of the undercapitalized categories can result in actions by regulators that could have a material effect on operations. At December 31, 2005 and 2004, the most recent regulatory notifications categorized the banks as well capitalized under the regulatory framework for prompt corrective actions.  There are no conditions or events since that notification that management believes have changed the institutions’ category.

Actual and required capital amounts and ratios are presented below.

NOTE 23 - STOCK OPTION PLANS

Options to buy stock were granted to directors and employees of the Company under the Company’s Stock Option Plan, which was adopted in 2003 and provides for the issuance of up to 578,813 options, of  which 390,333 are still available for granting at year-end 2005.

Exercise price is the market price at date of grant, so there is no compensation expense  recognized in the consolidated statements of income.  The maximum option term is ten years, and options vest immediately for the directors’ grant and over four years for the employees’ grants.  The weighted average remaining contractual life is 8.3 years at December 31, 2005.  A summary of the activity in the plan is as follows:

	2005				2004				2003

Subordinated debentures	(29,898		)	(31,090		)	(29,898		)	(29,898		)

The methods and assumptions used to estimate fair value are described as follows.

Carrying amount is the estimated fair value of cash and cash equivalents, interest-bearing time deposits, restricted stock, accrued interest receivable and payable, demand and all other transactional deposits, short-term borrowings, variable rate notes payable and subordinated debentures, and variable rate loans or deposits that reprice frequently and fully.   Security fair values are based on market prices or dealer quotes, and if no such information is available, on the rate and term of the security and information about the issuer.  For fixed rate loans or deposits and for variable rate loans or deposits with infrequent repricing or repricing limits, fair value is based on discounted  cash flows using current market rates applied to the estimated life and credit risk.  Fair values for impaired loans are estimated using discounted cash flow analysis or underlying collateral values.  Fair value of loans held for sale is based on market quotes.  Fair value of FHLB advances is based on current rates for similar financing. The fair value of off-balance-sheet items is based on the current fees or cost that would be charged to  enter into or terminate such arrangements, and are not considered significant.  The fair value of interest rate swaps is based on market prices or dealer quotes.

ITEM 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

In connection with its audits for the three most recent fiscal years ended December 31, 2005, there have been no disagreements with the Company’s independent registered public accounting firm on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

ITEM 9A.CONTROLS & PROCEDURES

Disclosure Controls and Procedures

As of the end of the period covered by this report, an evaluation was carried out under the supervision and with the participation of the Company’s management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Based on their evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are, to the best of their knowledge, effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms as of such date.

Our management has evaluated our internal control over financial reporting and there were no changes in our internal control over financial reporting that occurred during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

We, as management of the Company, are responsible for establishing and maintaining effective internal control over financial reporting that is designed to produce reliable financial statements in conformity with Untied States generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the Company’s system of internal control over financial reporting as of December 31, 2005, in relation to criteria for effective internal control over financial reporting as described in “Internal Control – Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission.  Based on this assessment, management concludes that as of December 31, 2005, its system of internal controls over financial reporting is effective and meets the criteria of the “Internal Control – Integrated Framework”.  Crowe Chizek and Company LLC, independent registered public accounting firm, has issued an attestation report dated February 10, 2006 on management’s assessment of the Company’s internal control over financial reporting.

Report Of Independent Registered Public Accounting Firm On Internal Controls

	Crowe Chizek and Company LLC Member Horwath International

Shareholders and Board of Directors

MainSource Financial Group, Inc.

Greensburg, Indiana

We have audited management’s assessment, included in the accompanying Report on Management’s Report on Internal Control Over Financial Reporting, that  MainSource Financial Group, Inc. maintained effective internal control overfinancial reporting as of December 31, 2005, based on criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).   MainSource Financial Group, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting.  Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.  Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances.  We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles.  A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U. S. generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

64

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, management’s assessment that MainSource Financial Group, Inc. maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Also in our opinion, MainSource Financial Group, Inc.  maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets as of December 31, 2005 and 2004, and the related consolidated statements of income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2005 of MainSource Financial Group, Inc. and our report dated February 10, 2006 expressed an unqualified opinion.

Exhibit 10.6

EXECUTIVE SEVERANCE AGREEMENT

                THIS EXECUTIVE SEVERANCE AGREEMENT ("Agreement") is entered into as of the 16th day of January, 2001 by and between INDIANA UNITED BANCORP (the "Company"), an Indiana corporation, and JAMES M. ANDERSON ("Executive").

RECITALS:

                A.            The Company considers the establishment and maintenance of a sound and vital management to be essential to protecting and enhancing the best interests of the Company and its shareholders;

                B.            The Company recognizes that, as is the case with many publicly held corporations, the possibility of a change in control may arise and that such possibility may result in the departure or distraction of management personnel to the detriment of the Company and its shareholders;

                C.            The Board of Directors of the Company (the "Board") has determined that it is in the best interests of the Company and its shareholders to secure Executive's continued services and to ensure Executive's continued and undivided dedication to his duties in the event of any threat or occurrence of a Change in Control (as defined in Section 1) of the Company; and

                D.            The Board has authorized the Company to enter into this Agreement.

NOW, THEREFORE, for and in consideration of the premises and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, the Company and Executive hereby agree as follows:

AGREEMENT:

For purpose of this paragraph (b), no act or failure to act by Executive shall be considered "willful" unless done or omitted to be done by Executive in bad faith and without reasonable belief that Executive's action or omission was legal, regulatory compliant, and in the best interests of the Company. Any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the Board, based upon the advice of counsel for the Company or upon the instructions of the Company's chief executive officer or another senior officer of the Company, shall be conclusively presumed to be done, or omitted to be done, by Executive in good faith and the best interests of the Company. Cause shall not exist unless and until the Company has delivered to Executive a copy of a resolution duly adopted by three-fourths (3/4) of the entire Board (excluding Executive if Executive is a Board member) at a meeting of the Board called and held for such purpose (after reasonable notice to Executive and an opportunity for Executive, together with counsel, to be heard before the Board), finding that in the good faith opinion of the Board an event set forth in clauses (i) or (ii) has occurred and specifying the particulars thereof in detail. The Company must notify Executive of any event constituting Cause within ninety (90) days following the Company's knowledge of its existence or such event shall not constitute Cause under this Agreement.

2

nominee for director, without written objection by such Incumbent Directors to such nomination) shall be deemed to be an Incumbent Director; provided, however, that no individual elected or nominated as a director of the Company initially as a result of an actual or threatened election contest with respect to directors or any other actual or threatened solicitation of proxies by or on behalf of any person other than the Board shall be deemed to be an Incumbent Director;

                                                (ii)  any "person" (as such term defined in Section 3 (a) (9) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and as used in Sections 13 (d) (3) and 14 (d) (2) of the Exchange Act) is or becomes a "beneficial owner" (as defined in Rule 1 3d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 25% or more of the combined voting power of the Company's then outstanding securities eligible to vote for the election of the Board (the "Company Voting Securities"); provided, however, that the event described in this paragraph (ii) shall not be deemed to be a Change in Control by virtue of any of the following acquisitions: (A) by the Company or any Subsidiary, (B) by any employee benefit plan sponsored or maintained by the Company or any Subsidiary, or by any employee stock benefit trust created by the Company or any Subsidiary, (C) by any underwriter temporarily holding securities pursuant to an offering of such securities, (D) pursuant to a Non-Qualifying Transaction (as defined in paragraph (iii)), (E) pursuant to any acquisition by Executive or any group of persons including Executive (or any entity controlled by Executive or any group of persons including Executive); or (F) a transaction (other than one described in (iii) below) in which Company Voting Securities are acquired from the Company, if a majority of the Incumbent Directors approves a resolution providing expressly that the acquisition pursuant to this clause (F) does not constitute a Change in Control under this paragraph (ii);

                                                (iii)  the consummation of a merger, consolidation, share exchange or similar form of corporate transaction involving the Company or any of its Subsidiaries that requires the approval of the Company's shareholders, whether for such transaction or the issuance of securities in the transaction (a "Business Combination"), unless immediately following such Business Combination: (A) more than 40% of the total voting power of (x) the corporation resulting from the consummation of such Business Combination (the "Surviving Corporation") or (y) if applicable, the ultimate parent corporation that directly or indirectly has beneficial ownership of 100% of the voting securities eligible to elect directors of the Surviving Corporation (the "Parent Corporation"), is represented by Company Voting Securities that were outstanding immediately prior to such Business Combination (or, if applicable, represented by share into which

3

such Company Voting Securities were converted pursuant to such Business Combination), and such voting power among the holders thereof is in substantially the same proportion as the voting power of such Company Voting Securities among the holders thereof immediately prior to the Business Combination,  (B) no person (other than any employee benefit plan sponsored or maintained by the Surviving Corporation or the Parent Corporation or any employee stock benefit trust created by the Surviving Corporation or the Parent Corporation) is or becomes the beneficial owner, directly or indirectly, of 25% or more of the total voting power of the outstanding voting securities eligible to elect directors of the Parent Corporation  (or, if there is no Parent Corporation, the Surviving Corporation) and (C) at least one-half of the members of the board of directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) were Incumbent Directors at the time of the Board's approval of the execution of the initial agreement providing for such Business Combination (any Business Combination which satisfies all of the criteria specified in (A), (B) and (C) above shall be deemed to be a "Non-Qualifying Transaction"); or

                                                (iv)  the shareholders of the Company approve a plan of complete liquidation or dissolution of the Company or a sale of all or substantially all of the Company's assets.

Notwithstanding the foregoing, a Change in Control of the Company shall not be deemed to occur solely because any person acquires beneficial ownership of more than 25% of the Company Voting Securities as a result of the acquisition of Company Voting Securities by the Company that reduces the number of Company Voting Securities outstanding; provided, that if after such acquisition by the Company such person becomes the beneficial owner of additional Company Voting Securities that increases the percentage of outstanding Company Voting Securities beneficially owned by such person, a Change in Control of the Company shall then occur.

                                (d)           "Date of Termination" means (1) the effective date on which Executive's employment be the Company terminates as specified in a prior written notice by the Company or Executive; as the case may be, to the other, delivered pursuant to Section 10, or (2) if Executive's employment by the Company terminates by reason of death, the date of death of Executive.

                                (e)           "Disability" means termination of Executive's employment by the Company due to Executive's absence from Executive's duties with the company on a full-time basis for at least one hundred eighty (180) consecutive days as a result of Executive's incapacity due to physical or mental illness.

4

                                (f)            "Good Reason" means, without Executive's express written consent, the occurrence of any of the following events after a Change in Control:

                                                (i)  (A) any change in the duties or responsibilities (including reporting responsibilities) of Executive that is inconsistent in any material and adverse respect with Executive's positions, duties, responsibilities or status with the Company immediately prior to such Change in Control (including any material and adverse diminution of such duties or responsibilities);

                                                (ii)  (A) a reduction by the Company in Executive's rate of annual base salary as in effect immediately prior to such Change in Control, or as the same may be increased from time to time thereafter, or (B) the failure by the Company to pay Executive an annual bonus in respect of the year in which such Change in Control occurs or any subsequent year in an amount greater than or equal to the annual bonus earned for the year prior to the year in which such Change in Control occurs, provided that Executive has met any requisite performance criteria threshold necessary to the payment of such annual bonus in respect of the year in which such Change in Control occurs or such subsequent year.

                                                (iii)  any requirement of the Company that Executive (A) be based anywhere more than thirty (30) miles from the office where Executive is located at the time of the Change in Control or (B) endure overnight travel on Company business to an extent substantially greater than the travel obligations of Executive immediately prior to such Changes in Control;

                                                (iv)  the failure of the Company to (A) continue in effect any employee benefit plan, compensation plan, welfare benefit plan or material fringe benefit plan in which Executive is participating immediately prior to such Change in Control or the taking of any action by the Company that would adversely affect Executive's participation in or reduce Executive's benefits under any such plan, unless Executive is permitted to participate in other plans providing Executive with the same benefits that the party effecting the Change in Control (or, if applicable, its Parent Corporation) provides to its most senior executive officers (or, in the case of a Parent Corporation, the most senior executive officers of its principal banking or financial services subsidiary) or (B) provide Executive with paid time-off in accordance with the most favorable time-off policies of the Company and its affiliated companies as in effect for Executive immediately prior to such Change in Control, including the crediting of all service for which Executive had

Notwithstanding anything herein to the contrary, termination of employment by Executive for any reason during the 30-day period commencing one (1) year after the date of a Change in Control shall constitute Good Reason.

                An isolated, insubstantial and inadvertent action taken in good faith and which is remedied by the Company within ten (10) days after receipt of notice thereof given by Executive shall not constitute Good Reason.  Executive's right to terminate employment for Good Reason shall not be affected by Executive' incapacities due to mental or physical illness and Executive's continued employment shall not constitute consent to, or a waiver of rights with respect to, any event or condition constituting Good Reason; provided, however, that Executive must provide notice of termination of employment within one-hundred twenty (120) days following Executive's knowledge of an event constituting Good Reason or such event shall not constitute Good Reason under this Agreement.

                                (g)           "Qualifying Termination" means a termination of Executive's employment (i) by the Company other than for Cause or (ii) by Executive for Good Reason.

                                (j)            "Termination Period" means the period of time beginning with a

6

Change in Control and ending eighteen (18) months following the end of the month in which such Change in Control occurs. Notwithstanding anything in this Agreement to the contrary, if (i) Executive's employment is terminated prior to a Change in Control for reasons that would have constituted a Qualifying Termination if they had occurred following a Change in Control; (ii) Executive reasonably demonstrates that such termination (or Good Reason event) was at the request of a third party who had indicated an intention or taken steps reasonably calculated to effect a Change in Control; and (iii) a Change in Control involving such third party (or a party competing with such third party to effectuate a Change in Control) does occur, then for purposes of this Agreement, the date immediately prior to the date of such termination of employment or event constituting Good Reason shall be treated as a Change in Control. For purposes of determining the timing of payments and benefits to Executive under Section 4, the date of the actual Change in Control shall be treated as Executives Date of Termination under Section 1(d).

2. Obligation of Executive. In the event of a tender or exchange offer, proxy contest, or the execution of any agreement that, if consummated, would constitute a Change in Control, Executive agrees not to voluntarily leave the employ of the Company that may employ Executive, other than as a result of Disability, Retirement or an event that would constitute Good Reason if a Change in Control had occurred, until the Change in Control occurs or, if earlier, such tender or exchange offer, proxy contest, or agreement is terminated or abandoned.

3. Term of Agreement. This Agreement shall be effective on the date hereof and shall continue in effect until the Company shall have given eighteen (18) months' written notice of cancellation; provided, that, notwithstanding the delivery of any such notice, this Agreement shall continue in effect for a period of eighteen (18) months following the end of the month in which a Change in Control occurs, if such Change in Control shall have occurred during the term of this Agreement. Notwithstanding anything in this Section to the contrary, this Agreement shall terminate if Executive or the Company terminates Executive's employment prior to a Change in Control except as provided in Section 1(j).

4. Payments Upon Termination of Employment.

(a)           Qualifying Termination — Cash Payment. If during the Termination Period the employment of Executive shall terminate pursuant to a Qualifying Termination, then the Company shall provide to Executive, subject to the provisions of Section 11 hereunder:

7

                (i)  within twenty (20) days following the Date of Termination a lump-sum cash amount equal to the sum of (A) Executive's base salary through the Date of Termination and any bonus amounts that have become payable, to the extent not theretofore paid or deferred, (B) a pro rata portion of Executive's annual bonus for the fiscal year in which Executive's Date of Termination occurs in an amount at least equal to (x) Executive's Bonus Amount, multiplied by (y) a fraction, the numerator of which is the number of days in the fiscal year in which the Date of Termination occurs through the Date of Termination and the denominator of which is three hundred sixty-five (365), and reduced by (z) any amounts paid from the Company's annual incentive plan for the fiscal year in which Executive's Date of Termination occurs and (C) any accrued vacation pay, to the extent not theretofore paid; plus

                (ii)  within twenty (20) days following the Date of Termination, a lump-sum cash amount equal to the sum of (i) Executive's highest annual rate of base salary during the 12-month period immediately prior to Executive's Date of Termination, plus (ii) Executive's Bonus Amount; provided, however, that if Executive's Date of Termination is within twelve (12) months of the earliest date on which termination by the Executive could otherwise be considered a Retirement ("Retirement Date"), such sum shall be multiplied by a fraction ("Adjustment Fraction"), the numerator of which is equal to the number of full months from the Date of Termination to the Retirement Date, and the denominator of which is equal to 12.

                (b)           Qualifying Termination — Continued Coverage. If during the Termination period the employment of Executive shall terminate pursuant to a Qualifying Termination, the Company shall continue to provide, for a period of one (1) year following Executive's Date of Termination, Executive (and Executive's dependents, if applicable) with the same level of medical, dental, accident, disability and life insurance benefits upon substantially the same terms and conditions (including contributions required by Executive for such benefits) as existed immediately prior to Executive's Date of Termination (or, if more favorable to Executive, as such benefits and terms and conditions existed immediately prior to the Change in Control); provided, however, that if Executive's Date of Termination is within one (1) year of Executive's Retirement Date, the number of years of continued benefits coverage (as described in this Section 4(b)) shall be equal to the product of (x) one, and (y) the Adjustment Fraction; provided, further, if Executive cannot continue to participate in the Company plans providing such benefits, the Company shall otherwise provide such benefits on the same after-tax basis as if continued participation had been permitted. Notwithstanding the foregoing,

8

in the event Executive becomes reemployed with another employer and becomes eligible to receive welfare benefits from such employer, the welfare benefits described herein shall be secondary to such benefits during the period of Executive's eligibility, but only to the extent that the Company reimburses Executive for any increased cost and provides any additional benefits necessary to give Executive the benefits provided hereunder. The Executive's accrued benefits as of the Date of Termination under the company's employee benefit plans shall be paid to Executive in accordance with the terms of such plans.

                (c)           Qualifying Termination — SERP Accrual. If during the Termination Period the employment of Executive shall terminate pursuant to a Qualifying Termination, the Company shall provide Executive with one (1) additional year of service credit under all non-qualified retirement plans and excess benefit plans in which the Executive participated as of his Date of Termination; provided, however, that if Executive's Date of Termination is within one (1) year of Executive's Retirement Date, the number of months of additional service credit (as described in this Section 4(c)) shall be equal to the product of (x) one, and (y) the Adjustment Fraction.

                (d)           Qualifying Termination — Voluntary Reduction of Payments. If during the Termination Period the employment of Executive shall terminate pursuant to a Qualifying Termination, Executive shall have the right to direct that the Company reduce the amounts which it is otherwise required to pay to Executive under Section 4 of this Agreement to the Safe Harbor Cap (as defined in Section 5(a) of this Agreement).

                (e)           Other than Qualifying Termination. If during the Termination Period the employment of Executive shall terminate other than by reason of a Qualifying Termination, then the Company shall pay to Executive within thirty (30) days following the Date of Termination, a lump-sum cash amount equal to the sum of (1) Executive's base salary through the Date of Termination and any bonus amounts that have become payable, to the extent not theretofore paid or deferred, and (2) any accrued vacation pay, to the extent not theretofore paid. The Company may make such additional payments, and provide such additional benefits, to Executive as the Company and Executive may agree in writing. The Executive's accrued benefits as of the Date of Termination under the Company's employee benefit plans shall be paid to Executive in accordance with the terms of such plans.

5. Certain Additional Payments by the Company. (a) Anything in this Agreement to the contrary notwithstanding, in the event it shall be

9

determined that any payment, award, benefit or distribution (or any acceleration of any payment, award, benefit or distribution) by the Company (or any affiliated entity) or any entity that effectuates a Change in Control (or any of its affiliated entities) to or for the benefit of Executive (whether pursuant to the terms of this Agreement or otherwise, but determined without regard to any additional payments required under this Section 5) (the "Payments") would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), or any interest or penalties are incurred by Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the "Excise Tax"), then the Company shall pay to Executive an additional payment (a "Gross-Up Payment") in an amount such that after payment by Executive of all taxes (including any Excise Tax) imposed upon the Gross-Up Payment, Executive retains an amount of the Gross-Up Payment equal to the sum of (x) the Excise Tax imposed upon the Payments and (y) the product of any deductions disallowed because of the inclusion of the Gross-Up Payment in Executive's adjusted gross income and the highest applicable marginal rate of federal income taxation for the calendar year in which the Gross-up Payment is to be made. For purposes of determining the amount of the Gross-up Payment, the Executive shall be deemed to (i) pay federal income taxes at the highest marginal rates of federal income taxation for the calendar year in which the Gross-up Payment is to be made, (ii) pay applicable state and local income taxes at the highest marginal rate of taxation for the calendar year in which the Gross-up Payment is to be made, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes and (iii) have otherwise allowable deductions for federal income tax purposes at least equal to the Gross-up Payment.

Notwithstanding the foregoing provisions of this Section 5(a), if it shall be determined that Executive is entitled to a Gross-Up Payment, but that the Payments would not be subject to the Excise Tax if the Payments were reduced by an amount that is less than 5% of the portion of the Payments that would be treated as "parachute payments" under Section 280G of the Code, then the amounts payable to Executive under this Agreement shall be reduced (but not below zero) to the maximum amount that could be paid to Executive without giving rise to the Excise Tax (the "Safe Harbor Cap"), and no Gross-Up Payment shall be made to Executive. The reduction of the amounts payable hereunder, if applicable, shall be made by reducing first the payments under Section 4(a) (ii), unless an alternative method of reduction is elected by Executive. For purposes of reducing the Payments to the Safe Harbor Cap, only amounts payable under this Agreement (and no other Payments) shall be reduced. If the reduction of the amounts payable

10

hereunder would not result in a reduction of the Payments to the Safe Harbor Cap, no amounts payable under this Agreement shall be reduced pursuant to this provision.

                                (b)           Subject to the provisions of Section 5(a), all determinations required to be made under this Section 5, including whether and when a Gross-Up Payment is required, the amount of such Gross-Up Payment, the reduction of the Payments to the Safe Harbor Cap and the assumptions to be utilized in arriving at such determinations, shall be made by the public accounting firm that is retained by the Company as of the date immediately prior to the Change in Control (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Company and Executive within fifteen (15) business days of the receipt of notice from the Company or the Executive that there has been a Payment, or such earlier time as is requested by the Company (collectively, the "Determination").  In the event that the Accounting Firm is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, Executive may appoint another regionally or nationally recognized public accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm hereunder).  All fees and expenses of the Accounting Firm shall be borne solely by the Company and the Company shall enter into any agreement requested by the Accounting Firm in connection with the performance of the services hereunder.  The Gross-up Payment under this Section 5 with respect to any Payments shall be made no later than thirty (30) days following such Payment.  If the Accounting Firm determines that no Excise Tax is payable by Executive, it shall furnish Executive with a written opinion to such effect, and to the effect that failure to report the Excise Tax, if any, on Executive's applicable federal income tax return will not result in the imposition of a negligence or similar penalty.  In the event the Accounting Firm determines that the Payments shall be reduced to the Safe Harbor Cap, it shall furnish Executive with a written opinion to such effect.  The Determination by the Accounting Firm shall be binding upon the Company and Executive.  As a result of the uncertainty in the application of Section 4999 of the Code at the time of the Determination, it is possible that Gross-Up Payments which will not have been made by the Company should have been made ("Underpayment") or Gross-up Payments are made by the Company which should not have been made ("Overpayment"), consistent with the calculations required to be made hereunder.  In the event that the Executive thereafter is required to make payment of any Excise Tax or additional Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code) shall be promptly paid by the Company to or for the benefit of

11

Executive.  In the event the amount of the Gross-up Payment exceeds the amount necessary to reimburse the Executive for his Excise Tax, the Accounting Firm shall determine the amount of the Overpayment that has been made and any such Overpayment (together with interest at the rate provided in Section 1274(b)(2) of the Code) shall be promptly paid by Executive (to the extent he has received a refund if the applicable Excise Tax has been paid to the Internal Revenue Service) to or for the benefit of the Company.  Executive shall cooperate, to the extent his expenses are reimbursed by the Company, with any reasonable requests by the Company in connection with any contests or disputes with the Internal Revenue Service in connection with the Excise Tax.

                6. Withholding Taxes.  The Company may withhold from all payments due to Executive (or his beneficiary or estate) hereunder all taxes that, by applicable federal, state, local or other law, the Company is required to withhold therefrom.

                7. Reimbursement of Expenses.  If any contest or dispute shall arise under this Agreement involving termination of Executive's employment with the Company or involving the failure or refusal of the Company to perform fully in accordance with the terms hereof, the Company shall reimburse Executive, on a current basis, for all reasonable legal fees and expenses, if any, incurred by Executive in connection with such contest or dispute (regardless of the result thereof), together with interest in an amount equal to the prime rate as published in the The Wall Street Journal from time to time in effect, but in no event higher than the maximum legal rate permissible under applicable law, such interest to accrue from the date the Company receives Executive's statement for such fees and expenses through the date of payment thereof, regardless of whether or not Executive's claim is upheld by an arbitration panel.

                8. Scope of Agreement.  Nothing in this Agreement shall be deemed to entitle Executive to continued employment with the Company or its Subsidiaries, and if Executive's employment with the Company shall terminate prior to a Change in Control, Executive shall have no further rights under this Agreement (except as otherwise provided hereunder); provided, however, that any termination of Executive's employment during the Termination Period shall be subject to all of the provisions of this Agreement.

                9. Successors; Binding Agreement.

(a)           This Agreement shall not be terminated by any Business Combination.  In the event of any Business Combination, the provisions of

12

this Agreement shall be binding upon the Surviving Corporation, and such Surviving Corporation shall be treated as the Company hereunder.

                                (b)           The Company agrees that in connection with any Business Combination, it will cause any successor entity to the Company unconditionally to assume (and for any Parent Corporation in such Business Combination to guarantee), by written instrument delivered to Executive (or his beneficiary or estate), all of the obligations of the Company hereunder.  Failure of the Company to obtain such assumption and guarantee prior to the effectiveness of any such Business Combination that constitute a Change in Control shall be a breach of this Agreement and shall constitute Good Reason hereunder and shall entitle Executive to compensation and other benefits from the Company in the same amount and on the same terms as Executive would be entitled hereunder if Executive's employment were terminated following a Change in Control by reason of a Qualifying Termination.  For purposes of implementing the foregoing, the date on which any such Business Combination becomes effective shall be deemed the date Good Reason occurs, and shall be the Date of Termination if requested by Executive.

                                (c)           This Agreement shall inure to the benefit of and be enforceable by Executive's personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.  If Executive shall die while any amounts would be payable to Executive hereunder had Executive continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to such person or persons appointed in writing by Executive to receive such amounts or, if no person is so appointed, to Executive's estate.

                10. Notice.

                                (a)           For purposes of this Agreement, all notices and other communications required or permitted hereunder shall be in writing and shall be deemed to have been dully given when delivered or five (5) days after deposit in the United States mail, certified and return receipt requested, postage prepaid, addressed as follows:

If to Executive:	At the address set forth below the signatory
If to the Company:	Indiana United Bancorp
	201 North Broadway

13

Greensburg, Indiana 47240

Attn: Chairman of the Board

or the such other address as wither party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

                                (b)           A written notice of Executive’s date of termination by the Company or Executive, as the case may be, to the other, shall (i) indicate the specific termination provision in this Agreement relied upon, (ii) to the extent applicable, set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive’s employment under the provision so indicated and (iii) specify the Date of Termination (which date shall not be less than fifteen (15) (thirty (30), if termination is by the Company for Disability) nor more than sixty (60) days after the giving of such notice). The failure by Executive or the Company to set forth in such notice any fact or circumstance that contributes to a showing of Good Reason or Cause shall not waive any right of Executive or the Company hereunder or preclude Executive or the Company from asserting such fact or circumstance in enforcing Executive’s or the Company’s rights hereunder.

                11.          Full Settlement; Resolution of Disputes. The Company’s obligation to make any payments provided for in this Agreement and otherwise to perform its obligations hereunder shall be in lieu of and in full settlement of all other severance payments to Executive under any other severance or employment agreement between Executive and the Company, and any severance plan of the Company. The Company’s obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action that the Company may have against Executive or others. In no event shall Executive be obligated to seek other employment or take other action by way of mitigation of the amounts payable to Executive under any of the provisions of this Agreement and, except as provided in Section 4(b), such amounts shall not be reduced whether or not Executive obtains other employment. Any dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration in Indianapolis, Indiana by three arbitrators in accordance with the rules of the American Arbitration Association then in effect. Judgment may be entered on the arbitrators’ award in any court having jurisdiction. The Company shall bear all costs and expenses arising in connection with any arbitration proceeding pursuant to this Section.

14

                12.          Employment with Subsidiaries. Employment with the Company for purposes of this Agreement shall include employment with any Subsidiary.

                13.          Survival. The respective obligations and benefits afforded to the Company and Executive as provided in Sections 4 (to the extent that payments or benefits are owed as a result of a termination of employment that occurs during the term of this Agreement), 5 (to the extent that Payments are made to Executive as a result of a Change in Control that occurs during the term of this Agreement), 6, 7, 9(c) and 11 shall survive the termination of this Agreement.

                14.          Governing Law; Validity. The interpretation, construction and performance of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of Indiana without regard to the principle of conflicts of laws. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which other provisions shall remain in full force and effect.

                15.          Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original and all of which together shall constitute one and the same instrument.

                16.          Miscellaneous. No provision of this Agreement may be modified or waived unless such modification or waiver is agreed to in writing and signed by Executive and by a duly authorized officer of the Company. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. Except as set forth in Sections 1(b) and 1(f), the failure by Executive or the Company to insist upon strict compliance with any provision of this Agreement or to assert any right Executive or the Company may have hereunder shall not be deemed to be a waiver of such provision or right or any other provision or right of this Agreement. Except as otherwise specifically provided herein, the rights of, and benefits payable to, Executive, his estate or his beneficiaries pursuant to this Agreement are in addition to any rights of, or benefits payable to, Executive, his estate or his beneficiaries under any other employee benefit plan or compensation program of the Company.

IN WITNESS WHEREOF, the Company has caused this Agreement to be executed by a duly authorized officer of the Company and Executive has

15

executed this Agreement, in each case as of the day and year first set forth above.
